Guggul Weight Loss


Pills

I was looking at sites with information on diet pills. One that caught my attention was touting eight patent-pending ingredients. Of the 10 or 12 listed, at least eight were plant extracts.

Naturally, pun intended, that started me thinking: How, exactly, does one patent a plant? Since that made my head hurt, I decided to look into one of those patent-pending ingredients, instead.   [Continue Reading ...]

Guggulsterones

Briefly, guggul is an extract from the resin of the mukul myrrh tree Commiphora mukul. It has been used, medicinally, since 600 BC for obesity, atherosclerosis, and inflammatory conditions. It is believed that the plant sterols, E- and Z-guggulsterone, are the bioactive compounds, the parts of the extract that interact with the body.

The Claims

Obviously, when use of a plant extract goes back 2600 years, there's bound to be a great deal of anecdotal evidence related to its medicinal properties. The idea of completely dismissing such information, out of hand, is as foolish as blindly accepting it. However, throwing in a little common sense and science is never a bad idea.

Now for the claims from one product [emphasis mine]:

Guggulsterones have been shown in studies to maintain normal blood lipid levels 10, support a fine skin texture by decreasing the appearance of blemishes, and optimize thyroid gland function (thus supporting ideal fat loss and body weight). And the best part… [product name] won’t strip away your muscle like other weight loss products.

We'll start with the study1 that supposedly supports these claims. Luckily, for a change, I was able to access the full study on JAMA. (The documentation for the supplement references the abstract from the same study.)

Cholesterol

Recent research indicates that the guggul compounds affect two specific hormone receptors. One of those receptors is related to cholesterol metabolism, leading researchers to question whether guggulsterones might be an effective treatment for high cholesterol. Hence the purpose of the study.

While not large, only 103 people in the Philadelphia area, it was a randomized, placebo-controlled clinical trial. Participants in this 8 week study were divided into three groups: low dose, high dose, and placebo. The low dose group was given 1000 mg tablets containing 2.5% standardized extract; the high dose group, 2000 mg tablets at the same concentration.

At the end of the trial, not only had the guggulsterones not reduced cholesterol levels, LDL-C (bad cholesterol) levels actually increased 4% and 5%, respectively. Additionally, HDL-C (good cholesterol) levels were depressed in both groups. With the placebo group, however, LDL-C decreased by 5%.

(A review of scientific evidence on the use of guggul for hyperlipidemia, performed by the Natural Standard Research Collaboration and published in 20052, agreed that the effects of guggulipid on cholesterol were not clear and there was "not enough scientific evidence to support the use of guggul for any medical condition.")

Thyroid Function

It was noted in the research, as in the claim for this supplement, that guggulsterones are reputed to have a positive impact on thyroid function. Within this clinical trial, due to its relationship with cholesterol, thyroid function was monitored and tested. "There were no significant changes in thyroid function as assessed by a sensitive third-generation TSH assay."

An article3 from the American Thyroid Association on thyroid and weight offers some guidance. The more active the thyroid, the higher a person's metabolism and, consequently, weight loss. It is possible to increase activity in the thyroid with hormone therapy. However, increasing thyroid function also increases appetite, potentially negating any benefit.

Furthermore, there may be significant negative consequences from the use of thyroid hormone to help with weight loss, such as the loss of muscle protein in addition to any loss of body fat. Pushing the thyroid hormone dose to cause thyroid hormone levels to be elevated is unlikely to significantly change weight and may result in other metabolic problems.

Muscle Loss

While, undoubtedly, dietary supplements do not (or should not) contain prescription-grade hormones, clearly the American Thyroid Association believes (see above quote) that altering thyroid function can lead to changes in muscles. It has been my experience that loss of muscle protein equals loss of muscle.

Conclusions

I'm no medical professional, although I do spend a good portion of my time studying health and wellness articles.

In the case of this diet pill ingredient, I have tried to use and review the supporting documentation. It seems to me that even the research cited doesn't support these claims.

MMM: Treatment for Anxiety


George Grie: Panic Attack
George Grie: Panic Attack

For those of us who suffer from anxiety disorders and panic attacks, every day is a bit of a coin toss. We don't know (necessarily) when we get up in the morning whether it's going to be a good day - or a bad day. What, exactly, might send us back under the covers.

There are two basic therapies that, to one degree or another, help take the edge off enough to get through. And, naturally, everyone is different - their anxiety manifests differently and different situations trigger the panic. But, by and large, there are two options.

CBT and medications. Good anxiety drug treatment centers will offer both.   [Continue Reading ...]

Just so we're all on the same page here, we're not talking about a case of nerves. This isn't sweaty palms or butterflies in the stomach over a first date. Although it can begin that way.

The kind of anxiety we're talking about is crippling, all out of proportion to the situation. Most everyone gets a little jumpy over new situations. But when it devolves into heart palpitations, shortness of breath, shaking, dizziness, and fight-or-flight reactions; when the physical and mental manifestations make it impossible to function - then, it's time to get help.

Cognitive-Behavioral Therapy (CBT)

CBT is not, in and of itself, therapy. Rather it is an umbrella term for therapies "based on the idea that our thoughts cause our feelings and behaviors, not external things, like people, situations, and events.[1]"

Cognitive-behavioral therapy doesn't say thoughts are wrong or tell people how to think. It begins with the premise that people who seek this form of therapy don't like the way they feel and want to do something to change those feelings. CBT therapists teach their clients how to do that. How to unlearn damaging reactions and behaviors.

For Example:

Years ago, I was married to a man who had issues with working every day and paying his portion of the bills. This caused me great anxiety, as we couldn't survive solely on my income. A natural anxiety, all things considered, that imagined starvation and homelessness.

The problem was, in my mind the situation magnified to such a point that spending any money caused intense panic. I simply 'knew' that the minute I paid out anything, something would happen and we'd be out on the street, living in our cars. Those thoughts became so internalized, so completely ingrained, that I couldn't pay bills.

Credit counseling, in this case, wasn't the answer. I had to change my thought process; recognize that I was way over the top and doing myself serious financial damage. It took time, and counseling, but I got there. (Sadly, not before I did some serious damage to my credit rating.)

Medications

There are a number of medications that are effective for anxiety. As with any other condition, not everyone responds to all treatments. Sometimes, the side effects override the benefits.

Rather than attempt to describe all forms of medications that are prescribed for anxiety disorders, let's look at what the medications (when they work) accomplish. In a nutshell, they reduce the physical symptoms of panic attacks. By eliminating or reducing these crippling mental and emotional reactions, medications offer patients time to calmly and rationally assess the situation and manage their response to the trigger.

For Example:

In my I-can't-pay-the-bills-cuz-I'll-end-up-homeless scenario, just opening a credit card bill was enough to make my heart pound, my palms sweat. I'd get dizzy and have trouble catching my breath. Once these symptoms kicked in, there wasn't much I could do but hold on for the ride.

With medication, the extreme physical fight-or-flight didn't happen. This aborted the roller coaster ride, before it even got started. Or, more accurately, lowered the peaks and raised the valleys of the anxiety.

Because I didn't have to deal with the immediate panic, I was able to (literally) take a deep breath and do the right thing. It didn't solve the problem of a husband who was financially irresponsible. But it did keep me from giving in to damaging behavior patterns.

Bottom Line

Anxiety and panic disorders are potentially crippling conditions. They keep people from functioning and, often, lead to additional problems because of the dysfunction. Untreated, life becomes a series of ever more crippling thoughts and irrational behaviors.

Therapy or medication alone is, frequently, insufficient to combat the combination of physical and mental processes that comprise anxiety and/or panic disorders. Reducing physical symptoms and retraining thought patterns is, from my experience, the best management option.

MMM: Testing for Fragile X Syndrome


Babies in Nursery
Photo: Reuters/Romeo Ranoco

Being beyond the fertile-Myrtle childbearing years, I don't often think about medical tests for newborns. An article I ran across on Reuters, however, made me stop and think. When is testing helpful and when is it simply too much information?

The article in question asked whether babies should be screened for untreatable diseases? My heavens, what a difficult question - and decision.   [Continue Reading ...]

A parental poll, cited in the article, was specifically asking about Fragile X Syndrome. An incurable genetic condition, FXS is caused by a change in the FMR1 gene which makes a protein that is required for proper growth of the brain. The mutation makes the gene produce little, or none, of this protein.

Symptoms include delayed motor skills (crawling and/or walking), hand clapping or biting, hyperactivity, mental retardation, speech and/or language delay, and avoidance of eye contact. Only about 1 in 4,000 boys and 1 in 6,000 girls develop Fragile X Syndrome.

Yes

There are those who want to know; who want to be prepared for possibilities. All possibilities.

As rare as the syndrome is, parents feel the need to know.

No

Some parents don't believe in testing infants unnecessarily. Others believe, as one mother put it, "Knowing can cause anxiety. The chances of it happening are very small; don't know how it will unfold. Not knowing will not make you treat your child a certain way."

Me (and You?)

Personally, I don't think I'd want to know. Being a chronic worrier, I'd drive myself and my child crazy looking for signs and symptoms that probably weren't there. And, heaven forbid, my child should develop FXS - would knowing sooner have any positive effect?

What about you? Would you want your child tested? Why or why not?

MMM: The Truth About Salt


Smoked Salt
Smoked Salt

Ha, ha, and ... ha! Okay, perhaps that was a tad uncalled for but, "I told you so" is just so rude.

What brought on this mini-gloat? An article I was reading, in Grist about a new study on salt, published earlier this month in JAMA. It appears that previous information may have been, what was that word? Oh, yeah. Wrong.

For years, we have been hounded by doctors, dieticians, and the USDA to cut back on salt. Salt would give us high blood pressure, heart disease, and strokes. We were doomed to bland, tasteless food or ... death.   [Continue Reading ...]

Compelling Findings

According to this study, published May 4th, "... low-salt diets actually increase the risk of death from heart attack and stroke -- and in fact don't prevent high blood pressure." And this isn't the first research to point out the disparity between dietary dogma and cold, hard facts.

Back in 2006, a report published in the American Journal of Medicine  found that "Lower sodium {emphasis mine} has been associated with stimulation of the sympathetic nervous system, that, in turn, has been associated with adverse [cardiovascular disease] and mortality outcomes. Sodium restriction may also influence insulin resistance."

Going back further, a 1998 article in Science , The (Political) Science of Salt, discusses the controversy. It mentions a Perspective: Biomedicine article which states: "Salt has little effect on blood pressure, and the most effective diet-induced changes in blood pressure can be achieved with a menu low in fat but high in calcium, fruits, and vegetables."

Salt and Fluid Balance

The body needs sodium. As Grist author, Kristin Wartman, explains:

Sodium is important for maintaining blood volume, it works in concert with potassium ... and ... calcium. ... [It] exists in all of the fluids in our body and is essential to water balance regulation, nerve stimulation, and proper function of the adrenal glands. It is also crucial to maintaining mental acuity ... This is part of the reason sodium deficiency (sunstroke, heat exhaustion) leads to confusion and lethargy as the human brain is extremely sensitive to changing sodium levels in the body.

Truth About Table Salt

Not to say that refined salt, the form that hits our french fries, is good for you. The article in Grist points out how salt is manufactured for the table. It's a tad scary.

In a nutshell, all trace elements are removed and the salt is heated to 1200° F. This leaves 100% sodium chloride, plus industrial additives like anticaking agents, dextrose, and aluminum. The additives turn the salt purple, so it's bleached to make it pretty and white.

Wouldn't call this a good food. (Unrefined sea salt is the best option.)

Bottom Line

I find all of this incredibly interesting. Early research indicated that salt was bad for blood pressure. That research stuck and, despite years of more accurate studies, those in charge of dietary recommendations refuse to change.

The potential correlation between sodium restriction and serious health issues is worth noting. As a society, we are suffering an increase in diabetes diagnoses that is nearly epidemic. Is this societal increase in insulin resistance a direct result of the push to limit salt intake? The timing is certainly intriguing.

Also interesting timing: milk and fresh fruits and vegetables are being priced right out of the diet of most American households. Yet, we put the blame for obesity, high blood pressure, and cardiovascular disease on sodium and fast food.

But that's a fight for another day.

Supplement Review


Creatine Kinase
Creatine Kinase

Anyone who reads this blog regularly knows that I have issues with supplements. Not the standard A, B-complex, C-type vitamins (although they can be iffy, too), but the this-will-cure-cancer-and-cause-world-peace supplements. The ones that no one really needs to be sticking in their system.

Primarily, beyond being grossly unnecessary and potentially unhealthy, I get upset with the companies that manufacture them. They create 'proprietary blends' to hide what's actually in their pills, then create huge hype to get people to throw copious amounts of cash at them.   [Continue Reading ...]

Take creatine supplements. (Actually, don't.)

Recently, I ran across a review on ConsumerLab.com that added some scientific weight to my worries. The summary information[1] explained some of the quality problems they'd found with, what they call, muscle enhancers. (Note: While I love my readers, I chose to not pay out copious amounts of cash to read the full report.)

Not every brand was a problem - several actually passed the testing. A couple, however, didn't do as well. They were found to contain mostly creatinine [2] - not creatine.

And one of the two actually had more contaminant than creatine. Which is what scares the crap out of me. Supplements aren't regulated and, without testing like this, heaven only knows what's really in them.

MMM: New Hepatitis C Drugs Approved


No Medical Advice

Back in January, I did a post about Hepatitis C treatment. There were 2 new drugs entering advanced testing stages, both of which had great potential for patients. Especially those patients whose genotype is resistant to treatment.

Well, this month, both Incivek from Vertex and Victrelis from Merck were approved by the FDA.   [Continue Reading ...]

Current Treatment Options

The best options, currently, for patients with HCV are pegylated interferon and ribavirin – a shot and a pill. But the side effects are horrendous - Alopecia, Anemia, Anorexia, Cough, Depression, Erythema, Fatigue, Myalgia, Nausea, and Pruritus; bad enough that many patients are forced to stop treatment before realizing full benefits.

Why? Because treatment is not quick – minimum 24 weeks, up to 48 weeks (or more) for resistant genotypes. Can you imagine a weekly shot that you know will hurt like the devil, make you sick to your stomach and achy (at least) all over? That will exhaust you and cause a level of over-all itching that would make a saint scream?

Add in the rarer, but more serious: "angina, arrhythmias, autoimmune conditions, blindness from optic neuritis or retinal ischemia or thrombosis, bronchiolitis obliterans, bronchoconstriction, cardiomyopathy, diabetes, gout, hepatic dysfunction, injection site necrosis, myocardial infarction, pancreatitis, pericardial effusion, pneumonia or pneumonitis, psychosis, relapse of drug addiction, renal failure, sarcoidosis, suicide attempt, thyroid dysfunction, and urticaria."[1] It becomes obvious – quite quickly – that anything which shortens the treatment period would be a god-send.

New Treatment Options

The new medications – the first released in 10 years, I must mention – work by, basically, starving HCV. They block a protein, protease, that the virus needs in order to reproduce.

Neither Incivek nor Victrelis are designed to replace current treatments; they are taken in conjunction with pegylated interferon and ribavirin. The addition of these new drugs, is expected to shorten treatment periods and dramatically improve outcomes.

Unlike current treatment options, these new medications will be made available, not only to patients who have never been treated, but to patients who failed earlier treatments. This is huge as with interferon and ribavirin, once a patient fails to reach a "sustained viralogic response" - little or no measurable virus in the bloodstream - the treatment is considered a failure.

Rarely is a second course of treatment considered.

Bottom Line

There are millions of people in need of an effective treatment option.

Statistics: "About 170 million people around the world are infected with hepatitis C, some 3.2 million of them in the United States. The blood-borne disease can lead to liver cancer, cirrhosis, liver transplants and death."

Although a slow-growing, asymptomatic virus – it is possible to have HepC for decades without symptoms – eventually, HCV will begin to seriously damage the liver. And, due to this liver damage, cause all manner of related health issues. It is irreversible (without treatment) and is the leading cause of liver transplants in the United States.

Thousands of patients have been putting off treatment, waiting and hoping for the release of these new medications. Having gone through the current standard treatment regimen with Mark, I can certainly understand why.

Here's hoping that a cure just hit the market.

MMM: Genetic Links


No Medical Advice

It's an interesting day on the gene front. Three studies, published today, bring news about genes related to depression and obesity.

These conditions each affect millions of people worldwide and the numbers are increasing at almost epidemic rates. The loss of working days and increased cost of medical treatment for related health problems is a staggering financial burden. Not to mention, the reduction in quality of life for those struggling with depression or obesity.

Any step toward improved therapies will have far-reaching effects.   [Continue Reading ...]

Depression

Two studies, one British and one American, have found a link to depression in the same DNA region: chromosome 3p25-26. Genetic studies of depression, historically, have a lot of trouble repeating results. For two research groups, working separately, to reach the same conclusion is pretty amazing.

This is an incredible leap forward toward, at the very least, potentially more effective treatments. With major depression hitting up to 20 percent of the population at some point and recurring depression affecting nearly 4 percent, treatment is critical. And although there are a lot of medications on the market, they're only helpful to about half of the patients who take them.

Obesity

Another British study, published in Nature Genetics, is looking at KLF14. This gene is already linked to type 2 diabetes and cholesterol, but it wasn't clear what it did. Until now.

Researchers believe that KLF14 is a type of master switch, controlling other genes found in fat tissue. Those other genes are linked to a number of metabolic functions, including body mass index, insulin, and glucose levels. In addition, there may be a connection to changes in muscles and the liver that are related to development of conditions such as diabetes.


Lots of exciting news, the impact of which will (probably) take years to realize. There will never be a 'skinny' pill or a 'happy' pill (at least I hope not), but anything that could reduce the risk of related conditions would be incredible.

Spinning Gears


Thrust Ball Bearing
Thrust Ball Bearing

I'm not certain what I was searching for, since once I started reading about thrust bearings, I got supremely distracted. Mostly, because I thought I should know what they are. I didn't, exactly.

And in trying to find out more, I had to research more. So many of the articles I found were written for people who know about engines. In self-defense, since my brain started bleeding, I went to my in-house expert.

In a nutshell, thrust bearings are designed to reduce friction and let moving parts move.   [Continue Reading ...]

Helical Gears
Helical Gears

Gearboxes in cars have what are called helical gears . They provide a smoother, quieter ride and better accommodate the increased turning force (torque) of high-speed engines. But they generate more energy (thrust) along the gear axis and, due to their design, more friction.

This increased friction is why thrust bearings are needed. These bearings reduce the friction, increase lubrication between the gear teeth. (I think that's about the simplest way I can say it; hope it makes sense.)

There are a lot of other bearings and thrust bearings in an engine. The 'throw-out bearing' in a standard transmission comes to mind. But, my brain hurts; I think I'm going to have a lie-down until the gears stop spinning.

MMM: Stress and Making Babies


Bath: Destress

The inclination, when faced with this headline: Stress relief may improve IVF success, is to say "Well ... Duh?!" For years, doctors have been telling couples, who are having a hard time getting pregnant, to "Relax!"

Granted, it seems like a verbal pat on the head; but, really, decreasing stress is never bad. Okay, there are ways  to reduce stress that are bad. But, less stress? Always good for the mind and body.   [Continue Reading ...]

Stress

We're not talking about "Oh, crap! The store's out of Joe's favorite chip dip!" here. (Well, unless Joe starts throwing punches if he doesn't get it.) Or, maybe, in a sense, we are.

It's the kind of stress that makes someone physically and emotionally ill. And it isn't the same from person to person. I hate crowds - with a passion; the thought of December in a mall sends me into a panic. But I have friends who love it.

And - it's not (generally) a one-off deal. For example, if I were married to dip-loving-Joe, the first tantrum probably wouldn't overly stress me. But, after a couple of years, the idea of shopping and risking his wrath would send me over the edge - every time I had to go to the store.

Causes aside, the symptoms of being stressed are pretty similar, across the board.

Physical Effects

Looking at it, this is a fairly consistent list:

Headaches, neck and back pain, shaky or sweaty hands, drymouth, dizziness, frequent colds or allergy attacks - just start the list. Some people eat more, stutter and stammer, blush a lot, sleep more. Personally, I suffer stomach problems, loss of appetite, heart palpitations, insomnia, ringing in my ears, and grind my teeth more. (Wow, that's a lot of misery.)

Mental/Emotional Effects

There is an even longer list of stress-induced problems:

Forgetfulness, nightmares, depression or mood swings, confusion, anxiety, inability to make decisions, frustration, paranoia, and feeling overwhelmed are not uncommon. I tend to become more uncoordinated, irritable, withdrawn, insecure, unfocused, and jumpy. When I'm stressed, loud noises nearly do me in.

Basically, unrelieved stress makes functioning a real challenge. And increases the difficulty level of ... life, the universe, and every single day - a hundred-fold, or more.


Now, imagine trying to convince your body to let sperm meet egg; to let that chance at new life attach itself and grow into a new, wonderful person.

Frankly, if I were that life -- waiting to happen? I'd just sit back, whistle softly, and wait for the next bus. This one's way too toxic.

And if Joe's driving the bus? Fuhgeddaboudit!

The Missing Day


Anastasis Pio Christiano
Source: Wikimedia Commons

There are many things, about the life of Christ upon which most theologians agree: He was born in 6BC, ministered for just over 3 years, died on a Friday in 33AD, and rose again on Easter Sunday.

It has also been believed, for generations, that the Last Supper was held on Maundy Thursday. Well, maybe not. With the help of astronomers, a scientist has recreated an earlier calendar and offers an explanation for what many call The Missing Day.

The Gospels detail the activities of Jesus and his disciples during the week before the crucifixion. Based on calculations from a common calendar, Christ took Wednesday off. Nothing, it appears, happened on that day.   [Continue Reading ...]

Historians and theologians have, historically, assumed that all of the timelines in the Gospels were based on the same calendar. However, if (as this article explains) there are 2 calendars at play - things get a little clearer.

It also indicates, if I'm understanding the information, that (like Christmas) Easter could now have a fixed date - the first Sunday in April.

On the other hand, the crucifixion took place on the eve of Passover (Yom Shishi, that year) and the resurrection on the following Sunday (Yom Rishon) - making it logical (okay, stay with me) that Easter would be the second full day of Passover. Given the nature of the Hebrew calendar, Easter would frequently fall on a day other than Sunday.

Then, we have the Christian Church calendar, based on a formula from the Nicaean Council of 325AD. "In this system, Easter is celebrated on the first Sunday following the first full moon after the Spring equinox," which corresponds to the timing of the first Easter.

I'm beginning to get a serious headache and regret having read that first article. Just tell me when we're dying eggs and donning our bonnets. K?

Creatine Supplements


3D Model: Creatine
Source: Wikimedia Commons/
Ben Mills & Ephemeronium

This will, undoubtedly, come as no great surprise: It is incredibly difficult to find unbiased information on creatine supplements. Is it harmful? Is it effective? Is it actually in that pill you're thinking about buying?

That's the wall I keep hitting. Looking up the ingredient is one thing. Analyzing the supplement - quite a different situation.

So, in an effort to keep from frying my very last brain cell, let's look at creatine - alone.   [Continue Reading ...]

Creatine Basics

What Is It?

Simply put (we're protecting that last brain cell, after all), creatine is an organic acid found in vertebrates, made from amino acids in the kidney and liver, and located mostly in skeletal muscle. Existing in fish and meat, creatine is not found vegetables. Because the body can make it, it's considered a non-essential (not needed in the diet) nutrient.

What Does It Do?

Naturally occuring creatine is transported in the blood to tissues, like the brain and muscles, that demand lots of energy. In those muscles, creatine combines with a phosphate to become phosphocreatine (creatine phosphate) and making rapid energy production possible. In other words, it helps feed the muscles during brief, high-intensity exercise such as sprinting and resistance training.

Creatine Supplements

Creatine has become a very popular supplement with athletes, leading to many research studies into its effectiveness. Reviews are decidedly mixed.

Do They Work?

Several studies report an increase in muscle mass with creatine use. However, because creatine tends to raise fluid levels in muscle tissue, some experts question whether this is true muscle building. In addition, many of the studies have been small (40 participants or less), so the results are generally deemed insufficient to draw conclusions.

It's interesting to note that there is no evidence that creatine provides any benefit for a) aerobic exercise, b) people over 60, and c) endurance athletes. Which, given how creatine aids in rapid energy creation, makes a great deal of sense.

Are They Safe?

Heads? They might be. Tails? They might not.

Most of my sources mentioned some level of concern about kidney and liver damage. Those sources also indicate that people with underlying kidney or liver disease should probably not take creatine supplements. At the same time - often in the same paragraph - they state that no significant changes in kidney function markers or liver enzymes were noted.

Are There Side Effects?

Digestive system upsets, muscle cramps, heat intolerance and/or dehydration, changes in insulin activity, abnormal heart rhythms, and blood clots in the legs are consistently listed as possible side effects. Less serious issues include headache, dizziness, increased thirst, anxiety, and irritability. Allergic reactions, particularly asthmatic symptoms, were also mentioned.

Conclusions?

Who knows?

From what I've read, there's no definitive proof that creatine supplements are effective, beyond a very narrow group of younger athletes. And there isn't definitive proof that they aren't. {POP!}

Aw, shoot! There went that last brain cell.

MMM: Smoking and Diabetes


Diabetes Symptoms Chart

The big news story in health yesterday, or at least for me and mine, was about diabetes and nicotine.

A quick search on the subject brings up information dating back to, at least, 2005. Smoking is bad for diabetics. Studies have been done - over, and over, and over again.

Results - over and over and over again? Smoking is bad for diabetics. I'm sensing a pattern here.

But, based on the most recent study, we now know exactly what component is causing all of the trouble. Seriously? Did we really not know before?   [Continue Reading ...]

The culprit is ... wait for it ... Nicotine.

What I found interesting is the phrasing found in of some of the news stories. (Emphasis is mine.)

For one:
... their tests showed concentrations of nicotine on the order of what is generally found in smokers causes HbA1c levels to rise.
and another:
... found that nicotine, when added to human blood samples, raised levels of hemoglobin A1c (HbA1c) by as much as 34%.
and, yet, another:
Using human blood samples, the scientists showed that nicotine concentrations typical of those in smokers appeared to raise long-term blood sugar levels in diabetics.

I have to say - hmmmm? Either all of the sources I read - or there's an interesting point here.

The study, as best I can surmise, was not done on diabetic or pre-diabetic smokers. Or even on the blood of diabetic or pre-diabetic smokers. It appears that the study involved adding nicotine to blood samples - in an amount that was judged to be "typical of those in smokers." Hmmmm?

Not being a scientist, I can only question what I read. As a curious soul, with a ... questioning ... mind, I do have to wonder. Is adding nicotine - a lab-created solution, I assume - to blood samples, in whatever quantity, the same as what happens to the blood in the body of a smoker?

What do you think?

MMM: Cell Phones and Brain Activity


No Medical Advice

I ran across an interesting report about the impact of cellphone use on the brain.

For years, we've been told that cellphone use will cause brain tumors -- or they won't. Every study that 'conclusively' proved one side of the debate was countered with a report contradicting those findings. What were (are) we supposed to believe?

While I'm not certain that we, yet, have an answer, the latest study does offer some interesting information.   [Continue Reading ...]

Cellphones and Brain Cells

I know it seems backwards, but I'm presenting the results before the method. Frankly, because I find the method more interesting.

Study Results

This study showed that the brain reacts to the electromagnetic radiation from a cellphone. With less than an hour of contact, brain activity increased by 7 percent in the area nearest the antenna. Whether that change was good or bad for brain health, was not a goal of the study; so we just don't know.

Study Method

In a randomized study from 2009, forty-seven participants had their brain activity measured after holding cellphones to their left and right ears for 50 minutes. Not too exciting, you say? Just you wait.

(Yeah, I have a picture in my head of a bunch of people, with electrodes stuck to their heads, cellphones on each ear, sitting around doing nothing else for nearly an hour.)

Fearing that if the subjects of the study knew when/if the phone was active, it would stimulate brain activity, researchers created a blind: On the first day, none of the phones were on. The second day, only the right was turned on - and muted. No auditory stimulation.

I think that's pretty cool. But, perhaps, could have been a little ... cooler.

Study Modifications

First, the study could have been larger. The more bodies, the better - when it comes to scientific studies. Surely they could have found a couple hundred people, or more, with nothing better to do for a couple of hours. (Pick me! Pick me!)

Second, just to increase the randomization, why not have some of the phones on the left ear active on the second day. I know, activity is activity - but, again, this is supposed to be science. Randomize the randomization.

Lastly, were certain types of brain cells stimulated? Or all cells within a specific range? The report doesn't say, so we don't know if this was part of the research.


All in all, pretty interesting stuff. (Okay, I've officially become a science nerd.)

Apples and Bananas


Fruit

We, inadvertently, became part of an experiment in fruit ripening yesterday.

Part of our grocery shopping, we picked up some apples and bananas. The bananas were a little green - at least they were when Mark put them next to the apples on the lazy susan. By the time we were done repackaging and putting away, the 'nanners' were ... changed.   [Continue Reading ...]

I had heard that putting apples in a brown paper bag with unripe fruit would accelerate ripening. Yeah. Sure. Right. Well, ummm, perhaps I was wrong.

We noticed the bananas getting riper, so we moved the apples. 'Nanners' getting more yellow; put the apples in a brown paper bag. Still getting dark - moved the bag of apples.

It was, within recent memory, one of the oddest situations I'd ever witnessed. The closer we placed the apples to the bananas, the more the bananas ripened. While it may not work for all fruit, it certainly appears to work - in spades - with bananas.

Kinda fun, all in all.

MMM: Kidney, Liver, and Diabetes Diets


Liver Diagram
Source: pbiv.com

Given that we're dealing with active hepatitis C and high blood pressure and insulin-dependent diabetes, I was pretty certain what I'd be doing this week. However, we learned, last Thursday, that Mark has stage 3 kidney disease.

So, I'm doing a mad scramble to learn everything I can about kidneys: health risks, disease symptoms, and dietary recommendations. Do this, don't do that; eat those, never touch these; and always remember ...

My brain is beginning to melt.   [Continue Reading ...]

One of the last things that the doctor and I talked about was the priority of a renal diet, over a diabetic diet. So, given the 5,000 other options, I decided to focus on food.

Electrolytes

Just as with the liver, electrolyte imbalances seem to be indicative of renal problems. In hepatic conditions, sodium and potassium balances are critical. Apparently, with kidneys, it's a phosphorus and calcium disconnect that triggers red flags.

Kidney Diagram
Source: bettercancersolutions.com

Phosphorus and Calcium

The body needs phosphorus to build and maintain bones and teeth, as well as nerve and muscle function. However, too much phosphorus keeps the body from absorbing calcium. When that happens, the body starts stealing calcium from bones to make up for it.

This leads to weak bones, as well as itchy skin, and bone and joint pain. Eating less peanut butter, cheese, nuts, and ice cream - foods high in phosphorus - is recommended. Non-cola drinks, sherbet, zucchini, broccoli, and non-dairy substitutes for milk products are preferred.

Calcium supplements may be required, with the addition of vitamin D to help maintain proper balance. Cutting out foods that are high in phosphorus may negate the need for calcium pills - something that your doctor should decide, after careful review of lab results.

Sodium and Potassium

Sodium is required by the body to manage fluid levels, regulate blood pressure, and control muscle contractions. Potassium keeps nerves and muscles working properly, especially the heart. Excess of both electrolytes are cleared through the kidneys.

When the kidneys aren't functioning properly, sodium levels may rise; leading to fluid retention in the hands, feet, and face, and an elevation in blood pressure. Excess potassium, found in greens, tomatoes, potatoes, bananas, broccoli, and chocolate, can cause irregular heart rhythms.

It's fairly easy to control salt intake. Simply take away the shaker and carefully read food labels. Obvious items to avoid include bouillon, canned soups and vegetables, salty snacks, bacon, cold cuts, and boxed dinner or side dish mixes. Colas tend to be rather high in sodium, as well.

Proteins and Carbs

This is where diabetes and kidney disease crash - violently.

The body converts carbs, which are hiding everywhere, into sugars. Therefore, a diabetic diet counsels low carbs, more protein. Not too difficult, until you factor in kidney disease.

One of the waste products created when the liver processes proteins is urea, a substance that contains nitrogen and clears through urine. When kidneys don't function properly, excess urea and nitrogen build up in the system. This condition, called uremia, can cause itching, mental impairment, nausea, and fluid build-up in the lungs or around the heart.

(One source indicated a direct correlation between excess urea and muscle loss.)

Obviously, too much protein is detrimental for anyone with kidney disease; just as it is for those with liver disease. But the alternative - carbs - are a no-no for diabetics. As with everything else, a balance between proteins and carbs is critical.

Our Dilemma

With the exception of calcium and phosphorus, these dietary restrictions aren't all that new to us. When Mark was dying from end-stage liver disease, we doled out milligrams of sodium and grams of protein like a miser pinches pennies. It wasn't easy, but we learned and got pretty good at it.

These days, we've got to factor in diabetes. That means the foods he ate, in massive quantities, to make up for being denied proteins are now (pardon the pun) off the table.

Frankly, I'm not quite certain how we're going to put all of this information together (and it's only a small part of what we have to consider) to create a diet that will not aggravate Mark's liver and kidneys, or shoot his blood glucose through the roof.

But I'm working on it. Any and all advice is extremely welcome.

Sustainable Scents


I got an email earlier from care2.com - a Daily Deal, which I pretty much planned to ignore. Not because I don't like saving money or don't like Care2. But because I only wear one scent and wasn't looking to change.

Naturally, curiosity won out in the end. I just had to see what organic perfume was all about.

Not only are their scents made from certified-organic ingredients with no petrochemicals or synthetic components, you can plant the packaging. That's right - the boxes are embedded with flower seeds and can be planted. Now that, my friends, is recycling at its very finest.

Maybe a new perfume wouldn't be such a bad idea, after all.

Menopause Good News


Woman Wiping Sweat

For months, I   whined incessantly about  strongly expressed my dislike for   hot flashes and night sweats. They were horrible. No matter how cool we kept it, I was constantly too warm. And every night, the minute I crawled under the covers, I was miserable.

They're mostly gone now, though my system still runs warmer than it did in my long-ago youth. Gone are the days of bundling in sweats, just because the A/C was on. And I don't shiver all night, just because the window is open. Kinda nice, actually.

Now, I find out that my suffering may have been a good thing.

A study, out today, suggests that hot flashes and night sweats early in menopause may mean a lower risk of heart attack in later life. There is, however, an important distinction here: Women who develop these wonderful symptoms later in the menopause cycle may actually be more at risk.

Guess I'd better figure out if I started out with misery. Or simply ended up that way.

We Should Be Cooling


Sun in Celestia

I was reading an interesting article about global warming, megadroughts, and the Earth's rotation. It was discussing super-droughts in the American Southwest, lasting thousands of years, that coincide with an increase in the temperature of the planet. A mean average temperature at or near where we're at right now.

In the past, millenia ago, these temperature changes and massive droughts were brought on by subtle changes in the Earth's orbit. Those changes are also a contributor to ice ages. Without man's intervention, the Earth heats and cools in trackable cycles.   [Continue Reading ...]

The existence of these natural cycles might lead one to believe that the Earth is going through a normal warming period. That man is not contributing, negatively, to the climate changes that we're currently experiencing. Undoubtedly, there are those who use that rationale to attack environmental beliefs.

A logical thought process that might even work, except for one minor detail: The Earth shouldn't be getting warmer.

Scientists have taken samples from a dry lake bed, the Valles Caldera in New Mexico. They developed a technique, analyzing sediment and soil bacteria, to determine temperature changes throughout the ages. Those studies tell them that, without man's intervention, we would be heading into a cooling period right now.

Losing Belly Fat


Voluptuary
Photo: Wikimedia/James Gillray

Before you listen to anyone who tells you how to get rid of belly fat, it helps to understand how it got there in the first place.

Naturally, bad eating habits are going to be a major culprit. Put a lot of fat, sugar, and empty calories into your body and you're going to get fat - all over the place. Trust me on that one.

When you start talking about belly fat, uncontrolled stress is also a big contributor. This isn't news. A study in 2000 reported that women who were vulnerable to stress could be slender all over and still have excess belly fat.

Why? Stress releases cortisol; cortisol causes fat to be stored in the middle of the body, around the organs. Reducing stress, or improving how you respond to stress, can reduce cortisol production and decrease fat around the belly.

So, while you're substituting carrots for candy and unsweetened tea for sugary soda, a few yoga and meditation classes might be just what the doctor ordered.

MMM: Antipsychotics and Pregnancy


No Medical Advice

The FDA announced, today, new labels for an entire class of medications: antipsychotics. The changes are primarily related to use during pregnancy; most specifically, during the third trimester.

Antipsychotics are used to treat Psychotic (characterized by delusions and hallucinations) Disorders, such as Schizophrenia. Some Mood Disorders with psychotic symptoms, such as Bipolar Disorder, are also treated with these medications.

To oversimplify, antipsychotics offer a host of potential, and potentially serious, side effects. The complications from untreated psychotic disorders are just as potentially serious. Therein lies the problem.   [Continue Reading ...]

Perhaps we should begin with a few definitions. Just what drugs are antipsychotics and what are the problems?

Antipsychotics

There are, primarily, two 'generations' of antipsychotics: typical (older) and atypical (newer).

Typical or First-Generation

Typical antipsychotics, discovered in the 1950s, weren't considered or called typical until after the development and clinical use of the newer medications. They work by keeping dopamine from attaching to receptors; by keeping dopamine levels down. The problem with this first generation was the almost certainty of extrapyramidal symptoms[1].

Drugs in this group include[2]:
  • Haldol (haloperidol)
  • Loxitane (loxapine)
  • Mellaril (thioridazine)
  • Moban (molindone)
  • Navane (thiothixene)
  • Orap (pimozide)
  • Prolixin (fluphenazine)
  • Stelazine (trifluoperazine)
  • Thorazine (chlorpromazine)
  • Trilafon (perphenazine)

Part of this group, Compazine (prochlorperazine) is a potent antipsychotic, but is only used as a short-term treatment for nausea and vertigo.

Atypical or Second-Generation

These drugs were developed in the 1990s, with the hopes that they would cause fewer extrapyramidal side effects[1]. They also work by blocking dopamine, but in different ways - not only from typical antipsychotics, but from each other.

Drugs in this group include[3]:
  • Clozaril, FazaClo (clozapine)
  • Fanapt (iloperidone)
  • Geodon (ziprasidone)
  • Invega (paliperidone)
  • Risperdal (risperidone)
  • Seroquel (quetiapine)
  • Zyprexa (olanzapine)

Also atypical, but developed more recently: Abilify (aripiprazole) and Saphris (asenapine). Symbyax, a combination of Prozac and Zyprexa (fluoxetine and olanzapine), is also included in this group.

FDA Drug Label Changes

Evidence

Based on a review of adverse events reports, the FDA has concluded that when mothers were treated in the third trimester with any antipsychotic, there was a risk of extrapyramidal signs[1] and/or withdrawal in their infants.

Symptoms included tremors, agitation, feeding disorders, drowsiness, abnormal changes in muscle tension, and respiratory distress. For many newborns, these effects subsided quickly; others required longer hospitalization.

Actions

Convinced that the risks apply to all antipsychotics, the FDA has modified the Pregnancy section of the labels for every drug in this class and notified healthcare professionals.

The new label offers more detailed information for psychiatrists, OB/GYNs, and their patients. It explains specific symptoms and that onset may be immediate or delayed. It reminds patients to not stop taking medications without consulting their physician and reminds physicians to closely monitor newborns.


  1. Extrapyramidal signs/side effects include sustained muscle contractions, causing muscle twisting and repetitive movements (dystonias); inability to sit still (akathisia); muscle rigidity and tremor (pseudoparkinsonism); involuntary repetitive movements, primarily of the mouth and face (tardive dyskinesia).

MMM: Acetyl L-Carnitine


Acetylcarnitine Structure
Acetyl L-Carnitine Structure

When I started reading about acetyl L carnitine, I expected the usual this-will-cure-everything-that-ails-you spiel for a supplement that would probably kill your liver, make your hair fall out, and give you warts on your chin. At the very least, it'd be a load of bunkum, hooey, and yeah-right claims.

I'm no medical expert; I just research this stuff. But it appears that I might have been wr..., wrr..., wrrr... in need of further information. So, let's see what we can find; shall we?   [Continue Reading ...]

The site that started this didn't really have any original information. They'd copied, verbatim and without attribution, from several sources: WebMD and Amazon.com, for two. Plagarism notwithstanding, there don't seem to be many issues with acetyl L-carnitine (ALC), and some interesting potential benefits.

What It Is

ALC is an altered (acetylated) form of L-carnitine, a form of an amino acid (lysine) that helps the body make energy. It is naturally produced in the body and, although found in both plants and animals, more concentrated in meat, poultry, fish, and dairy - animal sources. In typical metabolic fashion, the body converts L-carnitine to acetyl L-carnitine, and ... wait for it ... acetyl L-carnitine to L-carnitine.

What It Does

This converted form of L-carnitine helps fatty acids enter skeletal and cardiac muscle cells to produce energy. It also helps move other compounds out of those cells to prevent accumulation. Crossing the blood-brain barrier, ALC has been shown to act as an antioxidant on brain tissue. By relaxing smooth muscle cells, acetyl L-carnitine has the ability to widen blood vessels (vasodilation) and improve blood flow.

What It Means

One study found that, because it acts on skeletal muscle cells, "the major tissue of insulin-stimulated glucose disposal[1]," ALC may improve insulin-resistance in type 2 diabetics. Increased oxidant production and reduced L-carnitine levels are believed to contribute to negative symptoms of aging, making supplementation with ALC a potential treatment[2].

Additionally, due to its vasodilation properties, acetyl L-carnitine may benefit patients with conditions or risk factors related to restricted blood flow[2], such as:

  • Angina
  • Heart Attack
  • Heart Failure
  • Peripheral Artery Disease
  • Diabetic Neuropathy

Caveats

Most of these studies and the information available are based on research with animals. Research on the effectiveness of acetyl L-carnitine supplementation in humans is limited and the results tend to be mixed. In addition, oral ALC supplements were often less effective than intra-venous injections[2].

Lastly, due to the impact on blood vessels, ALC has known interactions with clotting medications, such as Acenocoumarol (Sintrom) and Warfarin (Coumadin). This could lead to excessive delays in clotting and an increased risk of bruising and bleeding[3].

Phenibut


Sleeping Girls
Photo: Wikimedia/Adrian Michael

While looking at (click here) sleeping pill reviews, I stumbled across another supplement ingredient that was completely new to me. Apparently, it's been available for a while and has a lot of scary anecdotal information.

It's called Phenibut and, according to a 2008 report published in the official journal of the American Academy of Clinical Toxicology, it is "A Novel 'Nutritional Supplement'."

That, my friends, just can't be good.   [Continue Reading ...]

What It Is

Wikipedia says that Phenibut, commonly known as Beta-phenyl-gamma-aminobutyric acid HCl, is a neuropsychotropic derivative of GABA with nootropic properties and anxiolytic benefits. Yeah, gave me a headache, too.

GABA Derivative

Basically, gamma-aminobutyric acid (GABA) is a natural chemical that the body manufactures to help nerves communicate. It cannot, however, cross over into the brain or affect the central nervous system.

By altering GABA (I refuse to even attempt to learn how), scientists created Beta-phenyl-gamma-aminobutyric acid HCl which can cross into and affect the brain and central nervous system. It was synthesized at the I. M. Herzen Leningrad Pedagogical Institute USSR and the Institute of Experimental Medicine, Academy of Medical Sciences USSR.

Because Russian scientists determined that it relieved stress and anxiety, without adversely affecting performance, they made Phenibut part of every cosmonaut's medical kit since Apollo-Soyuz.

What It Does

It's a neuropsychotropic, with nootropic properties and anxiolytic benefits! Weren't you listening? Okay, don't yell; I'm working on it.

Neuropsychotropic

For those of us who don't have a degree in psychiatric medicine, Phenibut changes brain chemistry. It crosses into the brain and, by definition, alters how we see, feel, understand, and react to life. So do Zoloft, marijuana, and LSD.

Nootropic

Nootropics are also called 'smart drugs' because they are reputed to improve, or enhance, concentration and memory. Initially, the definition from Dr. Corneliu E. Giurgea included the very important qualification of 'very few side effects'. Unapproved drugs or supplements may not be able to make the same claims.

Anxiolytic

Okay, this is actually a word I know! Woohoo! It's a class of drugs that work on brain chemistry to relieve symptoms of anxiety. They include Valium, Xanax, and Librium.

What It Means

Phenibut (by the above definitions) 1.) crosses into the brain; 2.) changes how we perceive and react to life, the universe, and everything; and 3.) makes us really, really relaxed about it. Doesn't sound all that bad, right? That's what Timothy Leary said, too.

Clinical Toxicology

Then, we have that scientific article about Phenibut withdrawal. Remember - The "Novel 'Nutritional Supplement'"?

The patient from this report used Phenibut for months, because he liked the way it made him feel. Three days before he came to the hospital, he stopped using (I can't think of a better term). His symptoms on arrival included agitation, psychosis (loss of touch with reality), and hallucinations.

According to the report, the patient required intubation[1] and sedation with benzodiazepines[2].

After 4 days, the breathing tube was removed; the sedatives were discontinued. He had "a normal mental status and his psychosis had resolved. He never developed seizures."

Why Should Anyone Care?

Okay. This patient used Phenibut. Some would say, he abused it. People intentionally use chemicals all the time - alcohol, marijuana, cocaine; even caffeine or tobacco.

Choice

If someone decides to indulge, it's a personal choice. They choose the chemical they're putting in their system. Right or wrong, they know what they're taking and do so intentionally.

It's an informed, if potentially foolish, decision.

No Choice

What if you just want to sleep through the night? Or lose a few pounds? Those Internet supplements claim to hold the solution to your problem. But what, exactly, are you taking? You can't always tell what - or how much of it - is in those magic little pills.

You aren't making an informed decision.

Knowledge

The more you know about ingredients, the more safe your decisions. We're all different; what works for me, might make Mark sick. That's why we let our doctors prescribe.

And read - a lot - about everything we take.


  1. Intubation, inserting a plastic tube into a patient's airway, isn't only used when patients aren't breathing on their own. It is also used to protect the airway when the body is in, or might slip into, a coma.
  2. Benzodiazepines are the opposite of anti-depressants. They are, chemically, designed to tranquilize.

Grow Me a Hot Wing, Please


Meats
Photo: Wikimedia/MutHwaBC

This story made me think of an episode of Eureka, right after the knee-jerk gagging reflex kicked in.

Apparently, a scientist in South Carolina is attempting to grow meat in a lab. And, he's not alone. There are, according to the article, a handful of scientists worldwide trying to do the very same thing.

I understand the logic behind the work: As the population of the world increases, we are running out of room to raise animals for food. By engineering meat in a lab, science "could help solve future global food crises." But, still ... ick?   [Continue Reading ...]

Which brings me to Eureka. In an episode from Season 2, while in the midst of a crisis (when aren't they), members of the town of geniuses start to get ... stupid. This leaves the sheriff (when doesn't it), not the sharpest of the residents, to save everyone.

It turns out that the woman who supplies chicken to the town cares just a little too much for her bird. Yup, bird. She only has one rooster that she is very, very attached to.

Rather than raise animals and have to kill them, she clones her rooster and grows 'chicken' in a building on her property. Turns out that one of the chemicals she uses in the cloning process interacts with the human brain - making everyone into idiots.

And that, boys and girls, is why we shouldn't try to 'grow' meat.

Okay, it wasn't real. But ... it could happen.

Humulus lupus? Not So Much


Humulus lupulus: Hops
Photo: Wikimedia/A. Masclef

If it's tough to find out what's in that handy-dandy "best weight loss supplement", that's nothing compared to hunting down any benefits. But, hey, that's actually the fun part.

For example, I stumbled across a supplement today that has Humulus lupus in it. Pretty interesting, until you realize that there is no such thing. Just don't tell that to the USDA researchers or the American Academy of Anti-Aging Medicine.

The actual plant is Humulus lupulus (I checked with itis [dot] gov) or Hops. While hops, a member of the same family that gives us marijuana, is reputed to have mild sedative properties, there is no clinical evidence. Many preparations contain so much alcohol that it's anyone's guess what's doing the sedating.

What is known is that Humulus lupulus contains phytoestrogens, chemicals found in plants that can act like estrogen. These chemicals are, alternatively, blamed for increased risk of hormone-dependent cancers and touted as protection against those same conditions. Mostly it's soy-based products that take the heat.

That doesn't mean popping supplements containing hops are good - or bad. It just means that there really isn't enough information to make an educated call. Wow, where have we heard that before?!

Detox Supplements


Pill Bottle

In the world of weight loss and diet supplements, the what is the best weight loss pill question gets a lot of attention: thousands and thousands of hits, no matter which search engine you use. It's a little unnerving to see just how much time, energy, and greed is tied into weight loss.

Then, if one looks at some of the search results, it simply gets sad.

It's easy to laugh and think, "Just what the world needs: another miracle supplement." Or, "Who do they think they're fooling?" But, then you have to realize that they think they're fooling you and me.   [Continue Reading ...]

These pill pushers (and I mean that in the kindest possible way) truly believe that enough people are willing to choke down 6 pills a day. Six pills with more than 30 ingredients and no documented health benefits, just hoping that - "You, too can lose a miraculous 24 pounds in 7 days." Good grief!

Every time I look at one of these clean-your-colon-and-lose-50-pounds supplements, I discover new and, heretofore, unknown (to me) leaves and seeds populating a 'new' cure-all pill. Just what good are Buchu leaves, anyway? Heck what are Buchu leaves?

Okay, I looked it up - couldn't stand it: Buchu is one common name for Agathosma species, a genus of more than 100 fragrant shrubs native to southern Africa. Two - Agathosma betulina and Agathosma crenulata - are cultivated for their essential oils. However, if a pill bottle only lists 'Buchu leaves' as an ingredient - how do you know what you're getting?

A. betulina has a history of use for gastrointestinal and urinary ailments and adds a black currant flavor and smell to cosmetics, soaps, and foods. Agathosma crenulata , also prized for its fragrant oils, is not a popular food additive due to high levels of a compound (pulegone) that may be toxic. I repeat - how do you know what you're getting in that detox/diet pill?

There's also the question of whether you're getting enough - or too much. What is the RDA for potassium or, for that matter, chromium? What, exactly, happens to the kidneys when you take so many herbs that have diuretic properties?

Frankly, there are a lot of questions that I can't answer. And, for me, if I can't answer why and how, I can't see swallowing 6 mystery pills every day.

Pantothenic Acid and Acne


Boiled Maine Lobster
Photo: Wikimedia Commons/Claude Covo-Farchi

Have you seen the newest player in the "best acne treatments" game? Pantothenic acid (vitamin B5) is the latest amazing acne cure I've seen hit the market. And, as expected, there's some interesting information out there.

B Vitamins

The eight B vitamins help the body break down fats, carbs, and proteins; turn food into fuel into energy; maintain healthy hair, skin, and liver; and ensure proper functioning of the nervous system. Vitamin B5, in particular, plays a part in production of red blood cells and adrenal hormones. It's being studied for potential use in lowering cholesterol and triglycerides, aiding (with vitamin C) in wound healing, and reducing symptoms of rheumatoid arthritis.

The National Institutes of Health indicate that the only effective use of pantothenic acid is in treating a vitamin B5 deficiency.   [Continue Reading ...]

Pantothenic Acid Basics

As with any vitamin or mineral treatment (for any condition), the assumption is that an underlying deficiency is to blame. Correct the deficiency; correct the condition. However, vitamin B5 is found in so many foods that it's difficult to imagine deficiency is common.

For example: wheat germ, whole-grain cereals and breads, brewer's yeast; legumes, lentils, peanuts, split peas, soybeans, sunflower seeds; avocado, broccoli, cauliflower, corn, kale, sweet potatoes, tomatoes; egg yolks, milk; organ meats (such as beef liver and kidney), chicken, duck, turkey; lobster, and salmon are all good sources of this vitamin.

Take out the sweet potatoes and (ewwww! ) organ meat, and I could easily see this as my regular diet.

Pantothenic Acid and Acne

From where I sit, I can actually see a couple of reasons why vitamin B5 would/could be considered helpful with acne.

  1. Stress: I've done a couple of posts (at least) about me, stress, and acne. In my system, if you combine the first two (me & stress), you get the third (acne). As B vitamins, especially B5, are frequently touted for their (as yet, unproven) anti-stress properties, I can see the rationale for a benefit to acne sufferers.

    Doesn't mean it's true, just that I can see the logic behind the argument.
  2. Hormones: This one is even more compelling. Acne begins in puberty, as hormones (generated by the adrenal glands) increase dramatically. Sebum production explodes, hair follicles clog up, and acne blooms. (A simplified and not exactly complete description, but sufficient for this discussion.)

    It could be presumed that Pantothenic acid's impact on adrenal hormones would translate to an ability to reduce breakouts. Only one small study, from the 1990s, proposes vitamin B5 as an acne treatment/cure. (Search: Lit-Hung Leung)

Pantothenic Acid Safety

Safe doses and levels, not surprisingly, is where things get a little sticky and where opinions begin to diverge. Thankfully, recommended daily intakes (RDIs) of vitamin B5 are fairly standard from source to source: Ages 14-18, 5mg; 19 and up, 5mg; pregnant women, 6mg; and nursing mothers, 7mg. (The EU RDA is 6mg; UK has no RDA for this vitamin, that I could find.)

Some experts add that pantothenic acid is safe at these RDIs, or moderately higher (a rather vague limit), but warn extremely high doses could, among other issues, increase the risk for bleeding. (The National Institutes of Health tell hemophiliacs to not take B5, as it might increase clotting time.)

Other sources insist that no upper limit has been established and even mega doses (10g/day) may only cause minor intestinal issues or diarrhea. Physician-monitored treatments for rheumatoid arthritis (2,000mg/day) and cholesterol reduction (900mg/day), while exceeding the RDIs, do not approach mega amounts.

There does seem to be a consensus that higher doses of a single B vitamin (no matter which one) can, over time, create an imbalance in the other B vitamins. In a nutshell, the body will pull what it needs from where it can find it to attempt to create balance. If you must take a supplement, B-complex (containing all eight B vitamins) is best.

Bottom Line?

It is somewhat logical, given how pantothenic acid acts on that body, that it could (in theory) have a benefit to acne sufferers - depending on the cause of their acne. However, there is virtually no documented evidence. Not to mention, there are no active or planned studies into B5 as an acne cure, or even treatment option.

There is also no consensus as to what doses of this vitamin are safe. Common sense would say that tons of anything - good or bad - isn't healthy. And when you start ingesting amounts that are 1,000-2,000 times greater than recommended, I have to believe that the risks are going to outweight any (unproven) benefits.

All of which takes us back to the standards: healthy diet, and keeping skin and hair clean is the best defense against breakouts. And, for pete's sake, keep your hands off your face! (That last one was for me. {wink})

MMM: Health-related Observances


No Medical Advice

This, the first Monday of 2011, seems like a good time to look at the health-related observances for January.

I do have one small problem. Last year, under a proclamation from President Obama, the second week of January was designated National Influenza Vaccination Week (NIVW). However, on December 3rd, the CDC changed it to the first full week in December.

It appears that NIVW may be a floating holiday. {wink}

However, the rest of our observances seem to be a little more permanently placed. From blood donation to cervical cancer screening to birth defects prevention to glaucoma awareness, they call attention to important health issues.   [Continue Reading ...]

 

National Birth Defects Prevention Month

The theme for 2011 is "Medication Use Before, During, and After Pregnancy."

Most birth defects can't be prevented because the causes are unknown. However, it is possible for women to reduce the risk to their unborn child. Taking a supplement containing 400mcg of folic acid daily, starting before pregnancy, has been shown to prevent serious defects of the brain and spine.

Just as critical to the health of the fetus is the health of the future mother. Pre-pregnancy check-ups and a careful review of the safety of all current medications cannot be over-emphasized.


National Volunteer Blood Donor Month

This is the month when the Red Cross thanks its blood donors and urges everyone who can donate to help save lives by giving blood. From americasblood.org:

  • It only takes about an hour - including registration, blood collection, and refreshments - to donate blood; two hours to donate platelets.
  • Whole blood can be donated every 56 days, allowing time for regeneration between donations; platelets, up to 24 times a year.
  • While red blood cells can be stored for 42 days (plasma, 5 days; platelets, frozen up to 12 months), most blood centers keep only a 3-day inventory.

Cervical Health Awareness Month

Most cervical cancers, seventy percent, are caused by two human papillomaviruses (HPVs). Any man or woman who is sexually active is at risk for exposure to HPVs. As with other STDs, condoms do offer some protection.

The greatest weapon in the fight against cervical cancer is the Pap test. This is because, unlike many other cancers, when caught early, cervical cancer is almost 100% curable. It helps that cervical cancer is rather slow progressing, so it's easier to catch at an early, treatable stage.


Glaucoma Awareness Month

A group of eye diseases that gradually destroy vision, glaucoma is the second leading cause of blindness in the world. Although more common in middle-aged and older people, glaucoma can affect persons of any age. The most common forms have virtually no symptoms, until (beginning with peripheral vision) severe vision loss occurs.

Glaucoma is the leading cause of blindness in African-Americans, with older Hispanics at nearly the same risk for this disease. Others at risk include people over 60, diabetics, the severely nearsighted, and relatives of those with glaucoma. Regular eye exams are critical.

The most common forms of glaucoma increase pressure in the eye, causing damage to the optic nerve. Although there is no cure, treatments are available to reduce intra-ocular pressure and, thereby, slow progression of the disease.

Thermal Receipt Printers


While searching far and wide for a replacement printer, I stumbled across information for a receipt printer. Not something I need, but (you know me) I had to see what was available.

There are two types of receipt printers: thermal and impact. Thermals, as the name indicates, use heat to create characters. Impacts use ink or ribbons.

Okay, there are inkjets and multi-function options, too. But I was mostly fascinated by the thermal vs. impact - the ones you probably see most often. Especially since the thermal papers have evolved to where they aren't obvious, when you first get the receipt.   [Continue Reading ...]

However, it is really easy to tell the difference in the two: just leave a receipt (one you don't need for warranty or return purposes - this is important), on the front seat of your car, in the Arizona summer sun. That little gray rectangle? Your thermal receipt.

Yes, you can do the same thing (very carefully) with a cigarette lighter. But that's not nearly as random (and budget-altering) as accidentally ensuring that those really (really) expensive jeans that really (really) didn't fit, are now yours for life.

But I digress.

What I didn't know, and wouldn't have believed, is that some of these little gems actually print in two colors. I figured that the machine applied heat to special, sensitive paper and characters appeared. More heat or less heat, makes darker or lighter letters and numbers.

All true. So, where does color, any color, fit into this equation? Seriously! Because, near as I can tell, these two-color printers don't use any different paper or supplies than the other thermals.

Color me ... confused.

MMM: Dyslexia Study Uses Brain Scans


No Medical Advice

Having two kids with learning disabilities, including dyslexia, a recent article definitely caught my attention. It addresses whether brain scans predict which dyslexics will read. An interesting idea.

Another small study; only 45 students aged 11 to 14. The teens were given a series of "tests to determine their reading abilities. Based on these, they classified 25 of them as dyslexics." That's a rather large percentage, given that (statistically) only 5 to 17 percent of kids suffer from this disability.

Before getting into the methods and results of this research, we should probably look at dyslexia.   [Continue Reading ...]

Dyslexia

What It Is

LD.org has a more elaborate explanation, but the basic problem is a neurological condition that interferes with the brain's ability to process and interpret information. One of the first signs seems to be difficulty identifying letters. The most commonly confused are b and d; p and q. This leads to a cascading series of problems.

By being unable to tell letters apart, kids develop problems reading, writing, and pronouncing words. Their communication skills are hampered. As these abilities become more critical to their education, they fall further and further behind their classmates.

What It Isn't

Dyslexia is not a sign of diminished intelligence. It is not laziness on the part of students. This condition is, also, not unique to or more prevalent in any particular socio-economic group.

The Latest Study

"The team used two different imaging techniques, including functional magnetic resonance imaging, which measures oxygen used by the brain during different activities, and diffusion tensor magnetic resonance imaging or DTI, which reveals connections between brain areas." During testing, they found some identified dyslexics had more activity in a specific part of the brain, as well as stronger connections in certain fibers that connect the front and back of the brain.

These results later correlated to improved skills in the students with increased brain activity. Interesting information and researchers are hoping that it will lead to improved teaching methods for dyslexic students.

I must agree with the only comment posted on the article: What does this mean for kids whose brainscans don't have this increased activity? Are programs going to be developed for children who might not improve?

Eating in Front of the Computer


Laptop Image
Credit: acobox.com

These little studies are interesting. Not necessarily valid for grand medical pronouncements, but they do make one think.

This latest, involving 44 men and women, tested whether mealtime distractions cause us to overeat, especially dessert. An interesting hypothesis, though hardly a definitive study. And, oddly, my circumstances tend to be the opposite.

At home, and at the office, I've always been one to work while I eat. I never noticed being particularly interested in sweets later. Or eating more because I'm not paying attention to the meal.   [Continue Reading ...]

In the study, participants who played a computer game during lunch ate more cookies, when dessert was offered 30 minutes later. Those who paid attention to the meal, and only the meal, indulged in fewer sweets. Additionally, the game players were less able to recall the order and content of their lunch, and reported feeling less full.

For me, doing other things while I'm eating generally causes me to eat less. I start feeling full and quit eating sooner when I'm paying attention to more than my meal. Undistracted, I'll eat everything but the plate.

Even eating the same amount of food, I will agree that I don't end up feeling as full when I'm multitasking. Probably because I tend to eat more slowly; nibbling at the food, while typing or reading a little between bites. My possible response to sweets, offered a half-hour later, did make me stop and think.

Because I nibbled my way through the meal and don't feel over-fed or too full, it is entirely possible that I would be more likely to nibble my way through cookies afterward. But, I am just as likely to decline. I make jokes about cookies and pies and other goodies, but really am not big on desserts or sweets on a regular basis.

What about you? Have you ever noticed that you eat more (or less) if you're doing something else while you're having a meal? (Snacks, for me, don't count. I'd eat a 20lb bag of chips or 10lbs of jelly beans without even thinking, if distracted by work or games.)

Omega-3 Fatty Acids and Depression


DHA Molecule

A recent article on whether Omega-3s help alleviate depression caught my attention - as much for the presentation as the information.

So often, when I'm digging for details on a condition or treatment, the sensationalism overwhelms the facts. I understand writing a 'catchy' title - to grab readers' attention. However, when the content borders on the theatrical, it's difficult for us laymen to understand what we're supposed to be taking away from the article.

Luckily, this latest offering from HealthDay, via Yahoo!, seems (at first blush) more professional than usual. We'll see, as we work our way through. (Let's cross our fingers?!)   [Continue Reading ...]

To start, I am no health expert. When I find an article on a subject that interests me, I always need to do a lot more reading. For example, before I can even attempt to judge information on omega-3s and depression, I have to educate myself on omega-3s. And - once again - I'm taking all of you with me!

Omega-3 Fatty Acids

Definition

Omega-3s are a family of polyunsaturated fatty acids (PUFAs) that the body cannot make on its own. They have been called 'essential' fatty acids (EFAs) because of their importance in normal growth and brain function. The three most common (and most studied) omega-3s are docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and alpha-linolenic acid (ALA).

Sources

DHA and EPA are found in certain cold-water fatty fish, e.g., sardines, halibut, herring, lake trout, mackerel, salmon, striped sea bass, albacore tuna, and whitefish. ALA, on the other hand, is a plant-based Omega-3 found in soy beans, walnuts, flaxseed, and canola and olive oils. The body converts ALA to EPA, and further to DHA.

Benefits

This is where the waters get a little muddy. Depending on the source (see the Google search results below), omega-3s do everything but the dishes. Proven benefits are a little harder to find, outside cardiovascular research.

There is evidence that EPA and DHA can (especially, when taken together) reduce inflammation, improve cholesterol levels, lower triglycerides, prevent plaque build-up in arteries, and improve blood flow. ALA (the form frequently found in supplements), on the other hand, doesn't seem to offer the same benefits.

Concentrated in the brain, omega-3s are believed to play an important role in cognitive function and behavior. Studies in Great Britain, Australia, and Indonesia showed that children whose diets were higher in omega-3s performed better in school, with fewer behavior problems. Hence, the hope for benefit to people with depression and behavioral disorders.

Omega-3s and Depression

The article that inspired this post is based on an analysis (as yet, unpublished and not peer-reviewed) of previous clinical trials. Paid for by the National Institutes of Health, researchers combined the results of other studies and looked for patterns of omega-3s' impact on depression. They found a lot of information, inspiring further research; but nothing actually provided definitive conclusions.

Part of the problem is that many of the studies involved DHA alone. Few note any benefit to this solo-therapy approach. (My digging into other sources, listed below, showed similar results.) As mentioned, combining DHA and EPA seems to be more effective - regardless of the condition being treated.

Another problem? Although there is an indication that DHA-deficiencies have been linked to depression, the clinical trials failed to note whether any of the participants actually suffered from deficiencies. I quote: "However, it's unknown if the depressed people in the study were DHA-deficient and therefore the supplements were simply returning their DHA levels to normal, or if an added boost of DHA/EPA was helpful even for those with sufficient levels, Davis said."

What bothers me - rereading that last sentence - is casually comparing DHA to DHA/EPA. Over and over, I have read that adding EPA (sometimes in large amounts) to DHA is much more effective than DHA alone. Lumping them together, in the same sentence as though they were interchangeable treatments, is a serious apples-and-oranges comparison that flies in the face of valid methodology.

(Without access to the actual paper being presented this week, it's impossible to tell whether the disconnect is a flaw in the science or in the reporting. In other words, I'm not certain whether the researchers are mixing a lovely fruit salad or if the reporter failed to properly set-up the quote. Common, but frustrating.)

Conclusions

Depression is a serious condition. Improperly managed (or ignored) the implications are literally life-and-death. From where I sit, as a sufferer, any nature-based treatment is exciting. Especially one that offers other health benefits.

Chemical anti-depressants, while immensely improved since the early days, are still chemicals. Often it's a crap-shoot whether any particular drug will be effective for any particular patient. And, even then, the side effects and/or interactions can be serious.

The most, from where I sit, that can be decided by this new information is that we need more information. Hopefully, quality research will follow.


As always, arbitrarily taking supplements - of any kind - is to be avoided. If you feel that adding omega-3s to your diet is a good idea, talk to your physician. Combining these supplements with cholesterol meds or blood thinners increases the effects and carries serious risks.

In addition, know the manufacturer. Just as fish can be contaminated with mercury and other pollutants, so can fish oil supplements.

MMM: Smoking Creates Criminals


Frankly, I had an immediate and very negative reaction to this headline: Heavy smoking in pregnancy linked to crime in offspring. Yes, part of it was because I'm a smoker.

But it also screamed of militant non-smoking clap-trap designed to terrify potential parents. Nonsense propagated by the anti-smoking lobby! (See? told you I had a strong reaction!)

Then I had to go and read the rest of the article. Ruined a perfectly good 'mad.'   [Continue Reading ...]

 
 

A little background: The study involved 4,000 adults, born to mothers who were enrolled between 1959 and 1966. Researchers collected data on the mothers' smoking habits during pregnancy. In 1999, when they were 33 through 40, a review was done of the offsprings' health and criminal records.

It was determined that when the mothers smoked at least a pack (20+ cigarettes) per day during pregnancy, their kids were 30% more likely to have a criminal record. Additionally, those same children were deemed more likely to repeat offend. Did I mention anti-smoking clap-trap?!

Well, maybe and maybe not. Even the researchers admit that they are unable to definitively prove causality - that smoking mothers give birth to future criminals more frequently than non-smoking mothers. At most, they suggest that heavy maternal smoking may present a risk factor. That I can accept.

On the other hand, which is what damaged my 'mad,' maternal smoking has been linked to smaller birth weights and other health issues in kids. Studies on animals suggest that nicotine has a negative effect on the developing brain, especially neurotransmitters. In turn, neurotransmitter malfunction is considered a factor in some disorders, including ADHD, bipolar disorder, and OCD.[1]

So, if we want to extrapolate:

  1. Maternal smoking exposes the fetus' developing brain to nicotine.
  2. Nicotine exposure has been shown to negatively impact developing neurotransmitters in the brain.
  3. Neurotransmitter problems may contribute to development of certain mental health conditions.
  4. Persons with some mental health disorders are more likely to engage in criminal behaviors.
  5. Therefore, ergo, and towit - maternal smoking contributes to criminal behaviors in their offspring.

It's a reasonable conclusion, given presumed truths. And, honestly, just one more reason to not smoke.

Vinegar and Acne


Lemons
Credit: bam.gov

Over time, science has improved the quality of life. Aspirin and penicillin offer treatment of previously untreatable conditions. I can't imagine having a headache or infection in the days before modern medicine.

However, there is a lot to be said for natural methods. One of my mothers-in-law swore by vinegar for just about everything. Research has proven her wisdom, repeatedly.

Of course, vinegar is also a popular part of a typical home remedy for acne. From what I've read, there are two quite scientific reasons for that.   [Continue Reading ...]

Vinegar and Skin Care

Acidity

Vinegar's main component is acetic acid. The amount in commercial distilled white and apple cider vinegars varies slightly from manufacturer to manufacturer. But, by and large, they are slightly less acidic than lemon juice. This makes vinegar a perfect astringent; ideal for reducing surface oil, a common contributor to breakouts.

If you've ever priced 'cosmetic' astringents, you know that a bottle of vinegar is going to be much, much cheaper. Because it's a natural product, without chemicals and preservatives, it's bound to be safer for most all skin types. I know that I have trouble with astringents irritating my face.

Since most natural skin care recipes call for diluting vinegar, I have less concern with burning my skin. And even greater savings.

Bacteria Fighting

Sebum, the substance that moisturizes skin and hair, is a popular 'food' of some bacteria that lives on the skin. As more sebum is produced, primarily during adolescence, the bacteria feeds and multiplies. Increased bacteria means increased white blood cell activity in the follicles. In a nutshell ... breakouts.

The natural disinfecting/antibacterial properties of vinegar make it a perfect treatment for acne. By reducing bacteria on the skin, vinegar also reduces white blood cell activity. This stops the acne cycle. And helps clear existing pimples.

See? Grandma did know what she was talking about.

Will This Be the Last 'Year of the Tiger'?


"Who among us will look tigers in the eye and say: 'We admired everything about you, except your very existence'?" WWF on YouTube

Makari's Whiskers
Nick Jewell, [cc-by-2.0] Wikimedia Commons

With 2010 being the Year of the Tiger, this is the perfect time to take a look at what the world is doing to and for our tigers. And never forget - we are all responsible for the health and safety of the world's animals. For tigers, the news isn't good.

Due to conflicts with humans and illegal trading in tiger parts, tiger numbers are 3.2% of what they were just 100 years ago. And, in only 10 years, 40% of existing tiger habitat has disappeared. Today, an estimated 3,200 tigers are trying to survive in a range that is a mere 7% of what it once was.   [Continue Reading ...]

Tiger Facts

All in the Family

There is only one species (Panthera tigris) that we call the Tiger. Over time, as populations became more isolated and scientific testing improved, variations within that species led to the identification of nine (9) sub-species: six (6) extant (living) and three (3) known to be extinct. The common names provide a good indication of the native locations for each.

From largest to smallest, (with range and estimated numbers), they include:

  1. Amur or Siberian Tiger (P. t. altaica ) Range: Russian Far East, Northeastern China
    Hunted to near-extinction by the 1940s, creation of protected areas and a ban on hunting helped bring them back. However, the fall of the Soviet Union saw an increase in poaching that continues to threaten their tenuous recovery. Today, the population is estimated at 450.
  2. Bengal Tiger (P. t. tigris ) Range: Indian Sub-continent
    With the largest numbers of any sub-species, these cats live in the forests and grasslands of Bhutan, Bangladesh, China, Nepal, Myanmar, and, primarily, India. Establishment of tiger reserves and national parks, as well as conservation efforts begun by Indira Gandhi, have undoubtedly contributed to the relative stability of this population numbering about 1,850.
  3. Caspian or Persian Tiger (P. t. virgata ) Range: Western and Central Asia - [Extinct]
    This third largest tiger sub-species (and second to become extinct) is believed to have shared a common ancestor with the Siberian sub-species, as there is only one genetic code letter difference in their DNA. Despite anecdotal evidence to the contrary and an extensive native range in which to hide (Iran, Iraq, Afghanistan, Mongolia, Kazakhstan, Caucasus, Turkey, Tajikistan, Turkmenistan, and Uzbekistan), scientists are convinced that the Caspian tiger is extinct and has been since the 1950s or, depending on the source, the 1970s.
  4. Indochinese or Corbett's Tiger (P. t. corbetti ) Range: Indochina, north of the Malay Peninsula
    Recognized as a separate sub-species in 1968, Corbett's tiger calls seven (7) Asian countries home. Found in hilly or mountainous forests typical at the borders of Cambodia, China, Lao PDR, Malaysia, Myanmar, Thailand, and Vietnam, recent records indicate a mere 350 of these critically endangered cats exist today.
  5. Malayan Tiger (P. t. jacksoni ) Range: Southern Malay Peninsula
    Living in the southern end of Thailand and Peninsular Malaysia, this tiger was (provisionally) designated a sub-species separate from it's northern neighbor in 2004. Similar in appearance to the Indochinese tiger, it more closely resembles the smaller Sumatran in size. Due to varying methods of estimating populations, the count for this sub-species has a rather wide range. However, most sources place it at around 500 individuals.
  6. South China or Amoy Tiger (P. t. amoyensis ) Range: Southern China - [Extinct in the Wild ?]
    Believed by many to be the evolutionary ancestor of all tigers, estimates placed the South China tiger population at 4,000 in the 1950s. Following village incursions and livestock deaths, the tigers were targeted in an "anti-pest campaign" that quickly and dramatically reduced their numbers. The IUCN notes that no wild South China tiger has been documented since the 1970s, while The South China Tiger Project mentions anecdotal data for 20 remaining in the wild. The captive population is 72 worldwide, with 57 in China that are showing signs of inbreeding.
  7. Sumatran Tiger ( P. t. sumatrae ) Range: Sumatra
    For more than a million years, these smallest living tigers have populated Sumatra's tropical jungles. These days, they are usually found in isolated and/or protected areas where, nonetheless, they continue to be threatened by expanding agricultural plantations and illegal trade in tiger parts. An estimated population of 400-500 has not been updated since 1998 and does not include the 51 tiger kills per year reported from 1998 to 2002.
  8. Javan Tiger (P. t. sondaica ) Range: Java - [Extinct]
    Roaming the entire island in the 1800s, Javan Tigers were hunted down as pests and nuisances until they were feared extinct in the 1960s. A small population was confirmed in 1971 and the Gunung Betiri was declared a reserve. Due to an inability to protect the reserve, only 3 individuals were documented in 1980. The sub-species became the third to reach extinction, sometime during that decade.
  9. Bali Tiger (P. t. balica ) Range: Bali - [Extinct]
    With the dubious honor of being the first to reach extinction, the Bali tiger was the smallest of the sub-species. More people on Bali and Europeans with improved firearms after WWI, led to increased deforestation and a rise in hunting tigers for sport. The last documented tiger was an adult female killed in the western part of the island on September 27th, 1937. Like the Caspian tiger, stories of sightings persisted for decades. However, scientists believe Bali has long lacked sufficient habitat to support even one tiger.

Location, Location, Location

In the last century, Panthera tigris ranged from the "forests of eastern Turkey and the Caspian region of Western Asia, across to the Indian sub-continent, China, and Indochina, south to Indonesia, and north to the Korean Peninsula and the Russian Far East," according to the WWF Tiger Factsheet. Today, however, tigers are limited to small pockets of China and southeast Asia, as well as far-eastern Russia.

Tigers no longer roam west of India and have vanished completely from the Caspian, Bali, and Java. Additionally, they are considered regionally extinct in Afghanistan, Iran, Kazakhstan, Kyrgyzstan, Pakistan, Singapore, Tajikistan, Turkey, Turkmenistan, Uzbekistan, and several Chinese provinces. The IUCN believes that these big cats "may still persist in North Korea," although there is currently no supporting evidence.

A number of methods are used by governments and conservation organizations to determine animal populations. Some work better than others; some groups are more accurate than others. In terms of recovery and survival, biologists look at the number of breeding pairs for a species or location which may be as few as 40%, or less, of total population. Therefore, a simple 'head count,' as it were, may not accurately represent the health and viability of a group of animals.

With an estimated 3,200 tigers left in the wild - and that may be a generous estimate - it's time to support governments and organizations in their efforts to help these beautiful cats. We've seen them hunted to the point of extinction all over the world. And learned what waiting too long to act can mean for sub-species like the Javan tigers.

Protecting habitats and prey species is a good start. Increasing penalties for trade in tiger parts couldn't hurt. But, from what I've read, finding ways to improve living conditions and income opportunities for the locals - that don't involve poaching and massive deforestation - would seem to have the best potential for success.

In a real sense, it's the "Give a man a fish ... " course of action that potentially can reap the greatest rewards for everyone involved. What do you think? How can the world best help, not just tigers, but all endangered species?

Substance Abuse and Rapid Detox


The news is filled with stories of addictions and revolving-door rehab issues. So many letters to advice columns start with "I love my spouse, but the {insert drug of choice} is destroying our relationship." Yet, no one wakes up one morning and decides to become an addict.

And they don't get there alone.   [Continue Reading ...]

I don't know anyone who snuck a beer, lit up a pipe, or stuck a needle in their arm the first time without external influence. At some point, someone said, "Try this, you'll love it." Or modeled behavior that indicated a smoke or a drink (or coke or Valium or heroin) was the way to deal with stress or frustration or unhappiness.

Not everyone who has a drink or smokes a cigarette or takes pain pills develops an addiction. There are people who try drugs, but never use again (heroin and crack being frequent exceptions, due to their highly addictive properties). For those who do continue to use, it's a slippery slope.

Once it takes hold[1], substance abuse[2] or dependence[3] becomes a downward spiral of increasing physical and mental need that may never end without help. Stopping substance abuse involves acknowledging the problem, discontinuing use, dealing with underlying causes, and developing a strong support system to avoid relapse. Chemical dependence, on the other hand, may also require medically-administered detoxification, due to often dangerous withdrawal symptoms.

Not all detox programs are created equal. They run the gamut from cold turkey through drug replacement therapy and rapid detox. Even the term rapid detox has different meanings - and methods - depending on the program center.

Historically, detox programs took months. It was painful and frequently dangerous. Rapid detox has gained popularity, because it reduces the cleansing process to a matter of days (usually 3 to 7) and is far safer than cold turkey. Medically administered, it usually incorporates some type of drug therapy to minimize the effects of withdrawal.

A more extreme form, sometimes (but, not always) called ultra-rapid detox, involves placing the patient under general anesthesia. This allows the body to rid itself of chemicals while the patient 'sleeps' through withdrawal. The risks associated with long-term general anesthesia, up to 24 hours in some programs, should never be minimized or ignored. Any center that offers this form of detox should be closely monitored and strictly regulated.

Naturally, the more quickly a patient can eliminate the toxins from their system, the more quickly they can focus their energies on getting completely well. Addiction is rarely 'cured' by simply flushing the body of harmful chemicals. Over time, changes in the brain and body become almost hard-wired and require long-term therapies to correct.

Rapid detox is proving highly effective in jump-starting the addiction recovery process. As long as the body is suffering, the mind cannot begin to focus on anything else. True healing cannot start until the patient is no longer fighting withdrawal.

Mental changes and underlying emotional or behavioral problems that make some patients more susceptible to addiction need to be resolved. Therapy, support groups, and lifestyle changes all go hand-in-hand with detoxifying the body. Habits need to be addressed, unlearned, and replaced with healthy behaviors.


1.  Commonly abused drugs cross the blood-brain barrier and alter chemistry in different parts of the brain. "Drugs of abuse affect the parts of the brain that control pleasure, motivation, emotion, and memory ... " Continuing use leads to further alteration in brain function, the inability to regulate behavior, and a need to use in order to feel 'normal.'

2.  DSM-IV defines Substance Abuse as "A pattern of substance use leading to significant impairment in functioning." Four symptoms are described: 1. failure to fulfill obligations at home, work, or school due to recurrent use; 2. repeated substance use in physically hazardous situations; 3. legal problems caused by continuing use; and 4. recurrent use despite significant social and interpersonal problems caused by the substance use. It is also considered a symptom of substance dependence.

3.  DSM-IV describes the symptoms of Substance Dependence as: 1. substance abuse; 2. continuing use despite related problems; 3. increased tolerance; and 4. withdrawal symptoms. Symptoms 3. and 4. are what commonly differentiate dependence from abuse.

Getting Old is Natural


As society ages, more and more products pop up on the market focusing on reducing signs and symptoms of getting older. Of course, we would all love to have skin that looks 20 years (or more) younger than our age. And anything that reduces the aches and pains (my knees are constantly screaming at me) which develop, and increase, over time would be more than welcome. Right?   [Continue Reading ...]

Now, I'm not saying that us old-folks shouldn't try everything we can to feel and look as healthy as we possibly can. Good diet, exercise, plenty of water - all great ideas.

And in our youth, many of us could easily burn off the pizza, fries, or milk shake calories. We came to expect that we would always have that metabolic zoom. I think that companies offering products like natural male enhancement supplements and magic skin elixirs pounce on that deeply ingrained expectation.

We don't want to believe that we can't burn off that extra slice of pizza or large chocolate shake (Okay, now I'm hungry!) simply by breathing. But, most of us can't after about age 35, and there just aren't any shortcuts to being and looking healthy. It takes work.

As we age, our bodies don't work quite the same as they did when we were 25. It's natural, if regrettable. Popping supplements just isn't the answer.

If it were, every medical center and pharmaceutical company in the world would be shouting the news from the roof tops. Since they aren't, I'm guessing those magic little pills are no more effective than a placebo - in most cases. What do you think?

With the exception of a daily multiple vitamin, do you use any supplements that have actually worked? What have you tried that didn't work so well? Feel free to share your experiences and opinions.

Should ProAmatine (midodrine) Be Available?

by

I had never heard of midodrine, a treatment for orthostatic hypotension, until I read: FDA relents from midodrine withdrawal plan. Once again, one must question the value of a watch-dog that barks, but never bites.  . . . 

right arrow image   Read More  Should ProAmatine (midodrine) Be Available?

Midodrine, marketed under the brand name ProAmatine, is prescribed for patients with low blood pressure who become dizzy or faint when they stand up. It was approved in 1996, based on initial treatment results, with the caveat from the FDA that a follow-up study would be conducted to actually prove that there were long-term benefits. That study, it seems, was never done.

Now, I realize that the FDA can't be everywhere. But this oops didn't require physically visiting a manufacturer. It simply involved finding and using a viable method for follow-up. We used to call them 'tickler files' and, rather than rely on memory, would put a note or other reminder into the appropriate month/year folder.

On a monthly basis, the notes in the applicable folder would be reviewed for necessary action. It's manual - stone-knives-and-bear-skins, as we used to say - but at least things were looked at. Unlike the midodrine situation, which was able to fly under the radar for 14 years.

If that weren't bad enough, after the FDA determined that 1.) the study was not conducted as required, 2.) the medication, therefore, had not been proven effective, and 3.) the drug should be pulled from the market, pending completion of the mandatory study - they caved. Note to drug makers: "Okay, you 1.) didn't do the work, 2.) told your Mom you passed, anyway, and 3.) we really need to flunk you. But, hey, we'll go ahead and let you perform surgery. Just try to finish your training before you kill someone."

Just when I thought the FDA might be getting a clue.

Enhanced or Arrhythmic?

by

Back in July, I posted about male enhancement pills, noting that good ol' Bob seemed a little scarce these days and perhaps it was a sign that the world had (or should) move on. Apparently, I had a point. At least according to the article I just read.  . . .

ECG Trace with Grid
CV Physiology.com Image

A clinical study of Enzyte, at Loyola University, showed that the supplement "causes electrical abnormalities in the heart" that could, in men with existing heart conditions, be fatal. The exact affect on the heart is prolongation of the Q-T interval, the time that it takes the heart to depolarize and repolarize. (For a clinical explanation, please click on the image.)

If I understand correctly, the heart beats and rests (in very simple terms) through each wave. During repolarization or resting, the heart fills with blood to be pulsed out to the body during the next depolarization or muscle contraction. When the pulse is too rapid, there is not enough 'rest' to sufficiently fill the heart with blood and the heart muscle becomes stressed from increased contraction (beating).

However, as Enzyte is reputed to do, extending the Q-T interval - again, if I understand correctly - would mean the amount of time that it takes the heart to contract, rest, and contract is longer. The electrical impulses from the heart through the body become fewer. Oxygenated blood is delivered less frequently and the heart muscle stays more relaxed.

Now, in my little non-medical mind, the risk is that the heart muscle becomes 'flabby' like any muscle that isn't used regularly. Over time, it doesn't want to contract as often as it did - decreasing blood flow and, potentially, developing an unhealthy rhythm as the muscle takes longer to respond to the chemical changes that tell it to "get to work!" Or I could have missed the boat completely.

Either way, anything that alters the electrical function of the heart - up or down - unless prescribed by a physician to correct an existing problem is something that needs a big rethink before blithely sticking it in the body.

Fat Cells, the Liver, and Type-2 Diabetes

by

While I don't usually follow HealthDay articles, one caught my eye today. Any information on diabetes is important, especially a study that questions whether Changes in Fat Cells May Pave Way for Type 2 Diabetes. But that was just the beginning.  . . . 

right arrow image   Explore  Fat Cells, the Liver, and Type-2 Diabetes

This recent study found that changes in fat cells, not the immune system, may be at the root of insulin resistance and type-2 diabetes. According to the summary and highlights1, inflammation in fat cells was critical to development of insulin resistance in mice. This inflammation also contributed to hepatic steatosis, or fatty liver disease.

A 2002 study, looking at the relationship between Hepatic Steatosis, Insulin Resistance, and Adipose Tissue Disorders, found a very similar correlation. In the earlier study, researchers found that treatment of fatty liver with leptin replacement also reduced insulin resistance. Although, they were unsure whether fatty liver contributed to development of insulin resistance, or vice versa.

With diabetes and liver disease at the forefront of our daily medical concerns, it is wonderful to see old assumptions being questioned and new ideas getting attention.

Natural Acne Treatments

by

Earlier I offered information about common ingredients in acne treatments, such as benzoyl peroxide. Many of these chemicals are harsh and can irritate the skin, which is why products like Pronexin tout their all-natural ingredients. The question, of course, is whether they work.  . . . 

right arrow image   Read More  Natural Acne Treatments

First of all, the claim of 100% natural may not be 100% true. It all depends, I suppose, how one defines natural. A couple of the ingredients I checked are synthetic analogs, lab-created.

As a side note: Pronexin shares a very, very similar ingredient list with a product called Zyporex. They both offer to 'disappear' acne in 72 hours and have - word for word - the same testimonials.

Tea tree oil is an essential oil from the Melaleuca alternifolia, a native Australian plant. With reputed antiseptic, antifungal, and antimicrobial properties, it has been used topically by aboriginals to treat a variety of conditions and infections. However, full-strength, tea tree oil can cause skin irritation, redness, itching, and blistering.

A single-blind study tested a five-percent tea tree oil solution against a five-percent benzoyl peroxide preparation. Results were comparable, with tea tree oil working more slowly, but causing fewer side effects. It should never be taken internally, due to risk of impaired immune function, diarrhea, and depression of the central nervous system.

Idebenone is an interesting drug. Originally developed to treat Alzheimer's and other cognitive disorders, it has had questionable success. A Swiss pharmaceutical company has recently begun recruiting for clinical trials into its use in treatment of neuromuscular diseases.

According to one article, idebenone is being marketed / promoted commercially as a synthetic analog of coenzyme Q10 (CoQ10). Although there is no clinical evidence to support it, this claim of properties similar to those found in (CoQ10) has led to idebenone's use in topical anti-wrinkle and anti-aging products.

Hyaluronic acid (HA) is a natural substance found in high concentrations in the eyes and connective tissue. Medical forms are extracted from rooster combs or created by bacteria in a laboratory. First used to speed tissue healing after eye surgery, it is also administered via injection to treat osteoarthritis in the knee, elbow, and shoulder; although some studies have raised doubts about its effectiveness.

Restylane and Juvederm are brand names for FDA-approved injectible forms used to temporarily fill wrinkles and scars, and plump lips. High levels of HA have been implicated in certain forms of cancer and Vitamin C may reduce metabolism of HA. A documentary ("The Village of Long Life" on 20/20) found that the Japanese villagers experiencing longer lifespans had a diet rich in starchy root vegetables that stimulated production of hyaluronic acid. They did not take supplements.

A large number of ingredients in Pronexin (and Zyporex) are oils: jojoba, avocado, lavendar, bergamot, camelia, rose hip seed, and amaranth; plus glycerin. Then, there is a fat-soluble form of Vitamin C (see impact on HA above) and something called retinol palmitate (I found retinol and retinyl palmitate, but no retinol palmitate), walnut shell as an exfoliant, sulfur to fight bacteria, and several herbs. Nothing clinically proven to improve or treat acne.

And, perhaps most importantly, no idea how much of any ingredient is used.

Acne Cream

by

Finding a site or page, touting an acne cream or treatment isn't difficult. Determining whether that product lives up to the hype takes a little more work. It may be easiest to start with common, effective ingredients.  . . . 

right arrow image   Read More  Acne Cream

Benzoyl peroxide is one of the most frequently used ingredients in topical acne treatments. It works by reducing Propionibacterium acnes (P. acnes), a common bacteria on the skin that lives on sebum, a fatty, waxy substance exuded by the follicles starting in puberty. Caution should be taken, as this ingredient can cause excessively dry skin and has a bleaching effect on hair, towels, sheets, and clothes.

Resorcinol, common in over-the-counter acne products, is also used to treat other skin conditions, like eczema and psoriasis. It works by breaking down hard, rough skin, including existing whiteheads and blackheads. Rarely used alone, it is often combined with sulphur for maximum affect. Like benzoyl peroxide, it can cause irritation and shouldn't be used with other possibly irritating products.

Salicylic acid helps slow down shedding of skin cells, thereby reducing clogged pores. Its ability to help break down blackheads and whiteheads makes it useful for other skin conditions, such as dandruff, psoriasis, calluses, and warts. Because it can also irritate the skin, salicylic acid should not be combined with benzoyl peroxide or resorcinol.

Alcohol and acetone are often combined to treat acne. Alcohol is mildly effective against microbes, similar to antibiotics without the risk of developing resistance. Acetone works to remove grease from the skin, but is not effective by itself.

Sulphur has been used to treat skin conditions for decades. Although it's unclear exactly how it works on acne, it is believed to kill bacteria on the skin. Due to the strong smell and risk of skin staining, it is usually combined with benzoyl peroxide or resorcinol in topical lotions and creams.

Regardless of ingredients, dermatologists frequently remind patients that acne doesn't disappear overnight. It can take weeks to see improvement in skin condition. And some ingredients (benzoyl peroxide and salicylic acid) must be used continuously or acne can return.

Bad Breath Treatment

by

Can't say that we're regular viewers of Mythbusters, but the other night was just too much fun. After mentioning one of the hosts' breath issues, they created a bad breath treatment from vodka and cinnamon. It really looked hideous - brownish liquid, sludgy at the bottom. Not good, at all.  . . . 

right arrow image   Read More  Bad Breath Treatment

Just as I was developing sympathy for the person who would have to try this concoction, it was pointed out that someone would have to judge whether it worked. Ewwww! After smoking, eating raw garlic and extremely smelly cheese - the nasty breath was ready. An associate was chosen and the before-and-after sniffing began.

Braver than I, that's for sure. Although, you've got to wonder who this poor guy upset, because in another segment he was volunteered to judge the effectiveness of a stinky-feet remedy, also based on vodka. Frankly, the beer-goggles experiment looked like much more fun. And a lot less disgusting.

Oh - the vodka-based remedies did work. No better or worse than mouthwash and foot baths. But, according to one man's nose, they did do the job.

Forensics and Drug Overdose

by

I must admit, this article, which I was reading at about 7:00am today, made me sit up (literally) and take notice. Not that doctors who over-prescribe or patients who doctor-shop is really new, not since Dr. FeelGood in the 60s/70s. It was the information about forensics and accurate determination of cause-of-death, primarily related to drug overdose, that caught my attention.  . . . 

right arrow image   Read More  Forensics and Drug Overdose

First, people with chronic pain - constant and debilitating, not the occasional sprain or backache - develop a tolerance for pain medications, especially opioids, over time. (That's one of the 'issues' with drugs like oxycodone and morphine.) Patients end up taking doses that could/would kill someone who has never used the medication before. Therefore, high amounts of fentanyl, for example, wouldn't necessarily be indicative of death-by-overdose in someone who has been on the medication for an extended period of time.

Second, some drugs (the aforementioned fentanyl, for one, and digoxin, a heart medication) are stored in the body's tissues - until death. At that time, they release into bodily fluids. This can make what may be a 'normal' dosage or acceptable levels appear lethal in post-mortem toxicology screens - or the reverse, depending upon from what part of the body the samples were taken.

Forensics is a relatively young science. It does not have the standards, protocols, and established methodologies found in other medical specialties, such as surgery or anesthesiology. In addition, "According to a 2009 report by the National Research Council of the National Academy of Sciences: 'Rigorous and mandatory certification programs for forensic scientists are currently lacking'."

This doesn't mean that every forensic result, or scientist, should be dismissed as fraudulent, any more than they should be blindly worshipped as gospel truth. Life is not a CSI episode, where cases are resolved quickly and correctly. Real-life forensic science has a long, long way to go to reach the level of accuracy and respectability that fiction can serve up every week.

Personally, I think it's a journey worth taking.
