WASHINGTON (Reuters) – More than half of older Americans taking an antidepressant for the first time were already taking another drug that could interact with it and cause side effects
, researchers reported on Friday.
And a quarter of patients who suffered side effects stopped taking antidepressants altogether, the study by a team at Thomson Reuters, the University of Southern California, Sanofi Aventis and elsewhere found.
“We found a concerning degree of potentially harmful drug combinations being prescribed to seniors,” Dr. Tami Lee Mark of Thomson Reuters, parent company of Reuters, said in a statement.
Other studies have found that older adults are often taking dangerous combinations of prescription drugs, but doctors are not getting the message, the researchers report in the American Journal for Geriatric Psychiatry.
The research team used a Thomson Reuters database of claims for Medicare, the federal health insurance plan for people over 65.
They found more than 39,000 patients who started antidepressants between 2001 and 2006. “Twelve commonly reported antidepressant side effects were identified in the month after drug initiation,” Mark’s team writes. More…

Study finds injectable and oral birth control do not adversely affect glucose and insulin levels
GALVESTON, December 17, 2010 – Fasting glucose and insulin levels remain within normal range for women using injectable or oral contraception, with only slight increases among women using depot medroxyprogesterone acetate (DMPA), commonly known as the birth control shot, according to new research from the University of Texas Medical Branch (UTMB Health) in Galveston.
The study, published in the January 2011 issue of Obstetrics and Gynecology and conducted over three years, is the largest to measure fasting glucose and insulin levels among women using DMPA, oral (desogestrel) contraception and non-hormonal (bilateral tubal ligation, condom or abstinence) methods. Researchers found that DMPA users’ glucose levels increased steadily during the first 30 months of use, with the greatest increase occurring during the first six months. The observed increases, which were less than those reported in previous studies, were not significant enough to cause concern. More…

A virus previously thought to be associated with chronic fatigue syndrome is not the cause of the disease, a detailed study has shown. The research shows that cell samples used in previous research were contaminated with the virus identified as XMRV and that XMRV is present in the mouse genome.
XMRV was first linked to chronic fatigue syndrome – also known as myalgic encephalomyelitis (ME) – in a study published in October 2009, where blood samples from chronic fatigue syndrome patients were found to have traces of the virus. XMRV had also been identified previously in samples from certain prostate cancer patients.
The new study, published in Retrovirology, identifies the source of XMRV in chronic fatigue syndrome samples as being cells or mouse DNA rather than infection by XMRV. The research does not rule out a virus cause of chronic fatigue syndrome – it is simply not this virus. More…

Training and ergonomic advice are more effective than anti-inflammatory drugs and cortisone injections in treating tennis elbow, and give fewer side effects. This is the conclusion of a thesis presented at the University of Gothenburg, Sweden.
The thesis describes, among other topics, the selection of treatment by healthcare personnel, their experiences when treating patients with tennis elbow, and the results from
a training programme for tennis elbow. Healthcare personnel in Halland, including GPs, orthopaedic surgeons and physiotherapists, replied to a questionnaire.I”It became clear that treatment with medication has side effects in many cases. Most side effects were reported from just those treatments that are often the treatment of choice for tennis elbow by GPs, which are cortisone injections and anti-inflammatory drugs”, says Pia Nilsson, physiotherapist and scientist at the Sahlgrenska Academy.

Vanderbilt study could lead to new treatments for neuromuscular diseases Researchers at Vanderbilt University have “engineered” a mouse that can run on a treadmill twice as long as a normal mouse by increasing its supply of acetylcholine, the neurotransmitter essential for muscle contraction.
The finding, reported this month in the journal Neuroscience, could lead to new treatments for neuromuscular disorders such as myasthenia gravis, which occurs when cholinergic nerve signals fail to reach the muscles, said Randy Blakely, Ph.D., director of the Vanderbilt Center for Molecular Neuroscience.

In developing countries where iron deficiency is prevalent, prenatal iron-folic acid supplementation increased offspring intellectual and motor functioning during school age, according to researchers from the Johns Hopkins Bloomberg School of Public Health.
They examined the intellectual and motor functioning of children whose mothers received micronutrient supplementation during pregnancy and found that aspects of intellectual functioning including working memory, inhibitory control, and fine motor functioning were positively associated with prenatal iron and folic acid supplementation. The results are published in the December 22/29 issue of the Journal of the American Medical Association.
“Iron is essential for the development of the central nervous system,” said Parul Christian, DrPH, MSc, lead author of the study and an associate professor with the Bloomberg School’s Department of International Health. “Early iron deficiency can alter neuroanatomy, biochemistry, and metabolism, leading to changes in neurophysiologic processes that support cognitive and sensorimotor development.” More…

Ancient food source may offer neuroprotection
Nutritional supplementation with Spirulina, a nutrient-rich, blue-green algae, appeared to provide neuroprotective support for dying motor neurons in a mouse model of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, University of South Florida neuroscientists have found. Although more research is needed, they suggest that a spirulina-supplemented diet may provide clinical benefits for ALS patients.
A spirulina dietary supplement was shown to delay the onset of motor symptoms and disease progression, reducing inflammatory markers and motor neuron death in a G93A mouse model of ALS. Spirulina, an ancient food source used by the Aztecs, may
have a dual antioxidant and anti-inflammatory effect on motor neurons, the researchers said.
Their study is published in the current issue of The Open Tissue Engineering and Regenerative Medicine Journal (3:36-41). More…
- “Not only did we make it absolutely clear that these pills had no active ingredient and were made from inert substances, but we actually had ‘placebo’ printed on the bottle,”
- patients taking the placebo doubled their rates of improvement to a degree roughly equivalent to the effects of the most powerful IBS medications.

BOSTON, Mass. (December 22, 2010)—For most of us, the “placebo effect” is synonymous with the power of positive thinking; it works because you believe you’re taking a real drug. But a new study rattles this assumption.
Researchers at Harvard Medical School’s Osher Research Center and Beth Israel Deaconess Medical Center (BIDMC) have found that placebos work even when administered without the seemingly requisite deception.
The study is published December 22 in PLoS ONE.
Placebos—or dummy pills—are typically used in clinical trials as controls for potential new medications. Even though they contain no active ingredients, patients often respond to them. In fact, data on placebos is so compelling that many American physicians (one study estimates 50 percent) secretly give placebos to unsuspecting patients. More…

Specially designed probiotics can modulate the physiology of host fat cells say scientists writing in Microbiology. The findings could lead to specialised probiotics that have a role in the prevention or treatment of conditions such as obesity.
Scientists from the Alimentary Pharmabiotic Centre (APC), Cork, University College Cork and Teagasc, in Ireland engineered a strain of Lactobacillus to produce a version of a molecule called conjugated linoleic acid (CLA). When this engineered bacterial strain was fed to mice, the researchers found that the composition of the mice’s fat tissue was significantly altered, demonstrating that ingesting live bacteria can influence metabolism at remote sites in the body.
CLA is a fatty acid that is produced in different versions by different bacteria. One type, called t10, c12 CLA, has been shown to be associated with decreased body fat in humans and other animals. t10, c12 CLA also has the ability to inhibit the growth of colon cancer cells and induce their death. However, this type of CLA is only produced by certain types of bacteria including Propionibacterium acnes – a skin bacterium that can cause acne. More…

HRR: ( Controversial ) This is an article on possibility and probability, not the source of any particular catalyst. It warrants posting from a forensic standpoint, and of course is purely hypothetical yet rational.

Bill Nye, in his debate with Ken Ham, alleged that science does not support belief in creation. Nye is wrong.
What really is science? There are two types of science. Empirical science is the knowledge of an event or a thing witnessed through our senses. You know that the moon exists. You can see it! You know that the chair exists because you can see it or feel its support.
The other type of science is forensic science. Forensic science is not direct knowledge but indirect knowledge of something. You didn’t witness the person’s death and you didn’t see how he died, but through careful collection and analysis of evidence you are able to determine how the death occurred.
The scientific method is used every day in forensic science to determine whether an event in a crime scene was an accident or by design and intention. Mathematical probability is a scientific argument and is frequently used in determining many issues of scientific inquiry.
The scientific method cannot be used to prove events that occurred outside of human observation. No one observed the origin of the universe by either chance or design (so neither can be proved by science), but scientific evidence via mathematical probability can be used to support either a chance or design origins for the universe.
Some things don’t need experiment or scientific proof. In law there is a dictum called prima facie evidence. It means “evidence that speaks for itself.” Of course, in the complexities of human society and relationships, prima facie may not always be what it seems. More…
- Breast cancer patients with high levels of vitamin D in their blood are twice as likely to survive the disease as women with low levels of this nutrient
Breast cancer patients with high levels of vitamin D in their blood are twice as likely to survive the disease as women with low levels of this nutrient, report University of California, San Diego School of Medicine researchers in the March issue of Anticancer Research.
In previous studies, Cedric F. Garland, DrPH, professor in the Department of Family and Preventive Medicine, showed that low vitamin D levels were linked to a high risk of premenopausal breast cancer. That finding, he said, prompted him to question the relationship between 25-hydroxyvitamin D — a metabolite produced by the body from the ingestion of vitamin D — and breast cancer survival rates.
Garland and colleagues performed a statistical analysis of five studies of 25-hydroxyvitamin D obtained at the time of patient diagnosis and their follow-up for an average of nine years. Combined, the studies included 4,443 breast cancer patients. More…
