  • A New Reason Why Red Meat, and Some Energy Drinks, May Be Bad for Our Heart

    ScienceNOW ^ | 7 April 2013 | Jennifer Couzin-Frankel
    Our guts are awash in bacteria, and now a new study fingers them as culprits in heart disease. A complicated dance between the microbes and a component of red meat could help explain how the food might cause atherosclerosis. The work also has implications for certain energy drinks and energy supplements, which contain the same nutrient that these bacteria like chasing after. Red meat is considered bad news when it comes to heart health, although studies aren't consistent about how much can hurt and whether it always does. Furthermore, it's not clear which components of meat are doing harm. Various...
  • Scientists Spot How Cox-2 Painkillers Raise Heart Risks

    New research has uncovered how some cox-2 painkillers increase the risk for both heart attacks and stroke. The once popular cox-2 drugs, Vioxx and Bextra, were pulled off the market in 2004 and 2005, respectively, after research showed that both raised the chances of cardiovascular trouble. Meanwhile, Celebrex, a painkiller in the same drug class that remains on the market, carries a "black box" warning alerting patients to potential heart risks. Now, a team of scientists from the University of Pennsylvania in Philadelphia say that, although cox-2 inhibitors are very good at inhibiting the workings of the cox-2 enzyme --...

    City Journal ^ | Spring 2011 | Steven Malanga
    Last October, embarrassing e-mails leaked from New York City’s Department of Health and Mental Hygiene disclosed that officials had stretched the limits of credible science in approving a 2009 antiobesity ad, which depicted a stream of soda pop transforming into human fat as it left the bottle. “The idea of a sugary drink becoming fat is absurd,” a scientific advisor warned the department in one of the e-mails, a view echoed by other experts whom the city consulted. Nevertheless, Gotham’s health commissioner, Thomas Farley, saw the ad as an effective way to scare people into losing weight, whatever its scientific...

    How specific digestive tract microbes react to a dietary lipid increases risk of heart attack, stroke and deathA new pathway has been discovered that links a common dietary lipid and intestinal microflora with an increased risk of heart disease, according to a Cleveland Clinic study published in the latest issue of Nature. The study shows that people who eat a diet containing a common nutrient found in animal products (such as eggs, liver and other meats, cheese and other diary products, fish, shellfish) are not predisposed to cardiovascular disease solely on their genetic make-up, but rather, how the micro-organisms that...
  • Atherosclerotic plaques formed during a late and limited time period in life

    Karolinska Institutet ^ | April 8, 2011 | Katarina Sternudd
    In a new study performed in humans, researchers from Karolinska Institutet have determined the age of atherosclerotic plaques by taking advantage of Carbon-14 (14C) residues in the atmosphere, prevailing after the extensive atomic bomb tests in the 50ties and 60ties. The findings, published in the scientific online journal PLoS ONE, suggest that in most people plaque formation occurs during a relatively short and late time period in life of 3-5 years. > "We suspected that the plaque would be substantially younger than the patients, who were on average were 68 years old at surgery, but we were surprised when we...
  • The Cholesterol Myths: Exposing the Fallacy that Saturated Fat and Cholesterol Cause Heart Disease

    Health911.com ^ | Review: [Joel M. Kauffman, Research Professor Chemistry]; Book: [Uffe Ravnskov, M. D., Ph. D.]
    <p>With courage and care Dr. Ravnskov exposes the lack of experimental evidence for the diet-heart theory, which claims that eating less fat and cholesterol will prevent atheroslcerosis (hardening of the arteries) and myocardial infarctions (heart attacks). By examining original peer-reviewed literature, the author finds no support for the diet-heart theory. He gives examples of scientific fraud among efforts to support the theory, including the deliberate selective omission of data points, and the deliberate assignment of subjects in a clinical trial to treatment or to control groups by physicians with the subject's medical records in hand. He shows how the abstract or conclusions of a number of papers are at odds with the actual data in the papers. He demonstrates how the use of one statistical method in preference to another can give a false impression that there is an effect, where there is, in fact, none. He shows how the reporting of differences in fatality rates by per cent reduction (say, a 50% reduction in relative risk) is actually misleading when the actual death rates are quite small in both the treatment and control groups of subjects in diet or drug studies. For example, a treatment that changes the absolute survival rate over a multi-year period from 99.0% to 99.5% represents a 50% reduction in relative risk, from 1% to 0.5% absolute. This is often described in papers as a 50% reduction in death rate. However, when the difference is barely significant statistically, as was often the case, Ravnskov points out that there is no real reason to recommend adoption of the treatment, especially if there are serious side-effects.</p>

    Chinese chemists have made sturdy nanotube sponges that can selectively absorb oil and volatile chemicals in preference to water. The sponges float on water and can absorb up almost 180 times their own weight in oil, giving them great potential for mopping up industrial spillages. 'We are very excited about the potential of our material,' says Anyuan Cao, who led the work at Peking University, Beijing, China. 'The sponges can absorb a variety of oils - from volatile solvents to thick and sticky oil - but they are also elastic and robust. They can be wrung out like towels and re-used,...
  • BUSM researchers propose a relationship between androgen deficiency and cardiovascular disease

    Boston University Medical Center ^ | Sep 25, 2009 | Unknown
    (Boston) - Researchers from Boston University School of Medicine (BUSM) in collaboration with researchers from Lahey Clinic Northshore, Peabody, Mass., believe that androgen deficiency might be the underlying cause for a variety of common clinical conditions, including diabetes, erectile dysfunction, metabolic syndrome and cardiovascular disease (CVD). These findings appear in the September/October issue of the Journal of Andrology. Androgens are a steroid hormone, such as testosterone, that controls the development and maintenance of male characteristics. In a number of studies, androgen deficiency has been linked to an increased mortality in men. Testosterone (T) is an anabolic hormone with a wide...

    COPENHAGEN — Rheumatoid arthritis and two other rheumatic diseases are as strong as diabetes as risk factors for cardiovascular disease, prompting a European League Against Rheumatism task force to issue the group's first consensus recommendations for managing cardiovascular risk in patients with rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis. “In our view, rheumatoid arthritis [RA], ankylosing spondylitis [AS], and psoriatic arthritis [PsA] should be seen as new, independent cardiovascular risk factors,” Dr. Michael T. Nurmohamed said at the annual European Congress of Rheumatology. “Very importantly, the risk is comparable to type 2 diabetes,” added Dr. Nurmohamed, a rheumatologist at the...

    AP Medical Writer The largest study ever of multivitamin use in older women found the pills did nothing to prevent common cancers or heart disease. The eight-year study in 161,808 postmenopausal women echoes recent disappointing vitamin studies in men. Millions of Americans spend billions of dollars on vitamins to boost their health. Research has focused on cancer and heart disease in particular because of evidence that diets full of vitamin-rich foods may protect against those illnesses. But that evidence doesn't necessarily mean pills are a good substitute...

    After 21 years of unsuccessful heart treatments, including several heart procedures, 68-year-old Coenie de Jongh was desperate. So when his cardiologist suggested a last-resort experimental therapy, it represented a literal life line.  Coenie, from Bloubergstrand near Cape Town, had his first heart attack at the young age of 40. A bypass operation followed and his condition improved, but seven years later Coenie’s health started deteriorating again. More operations and more intense treatment followed, but in 2002 his health took a real turn for the worse.  His condition was so bad he struggled to find a cardiologist who was willing to...

    Participants in a Federal Drug Administration (FDA) protocol at TCA Cellular Therapy utilizing stem cells to treat lower limb ischemia are experiencing increased mobility and decreased pain in lower legs. Lower limb ischemia is a condition where plaque build-up causes decreased circulation in the lower leg. Symptoms of the condition include intense pain and swelling. Study participants may have had different factors that contributed to their condition: a family history of Peripheral Artery Disease (PAD), history of smoking and other vascular conditions. Common among them however, were that more traditional treatments (utilizing stents and grafts) were ineffectual and that the...

    Amino acids: Key to a healthier heart? Could taking a few B vitamins cut your risk of a heart attack or a stroke? That's the suggestion from a study published last week in the British Medical Journal (BMJ).  The key is an amino acid called homocysteine, a substance made when the protein we eat is digested — already there is growing evidence to link it with cardiovascular disease, and even stroke. Homocysteine — with the help of the B vitamins including B12 and folate — is rapidly turned into other useful compounds such as the amino acids cysteine and...

    2006 DEC 4 - (NewsRx.com) -- Johns Hopkins scientists have successfully grown large numbers of stem cells taken from adult pigs' healthy heart tissue and used the cells to repair some of the tissue damage done to those organs by lab-induced heart attacks. Pigs' hearts closely resemble those in humans, making them a useful model in such research. Following up on previous studies, Hopkins cardiologists used a thin tube to extract samples of heart tissue no bigger than a grain of rice within hours of the animals' heart attacks, then grew large numbers of cardiac stem cells in the lab...
