Public release date: 27-Jan-2008 High-fat, low-carb diet may be an option when other treatments fail A modified version of a popular high-protein, low-carbohydrate diet can significantly cut the number of seizures in adults with epilepsy, a study led by Johns Hopkins researchers suggests. The Atkins-like diet, which has shown promise for seizure control in children, may offer a new lifeline for patients when drugs and other treatments fail or cause complications. For almost a century, doctors have prescribed an eating plan called the ketogenic diet to treat children with epilepsy. This diet often consists of a short period of fasting, […]
Public release date: 28-Jan-2008 Individuals who are physically active during their leisure time appear to be biologically younger than those with sedentary lifestyles, according to a report in the January 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Regular exercisers have lower rates of cardiovascular disease, type 2 diabetes, cancer, high blood pressure, obesity and osteoporosis, according to background information in the article. “A sedentary lifestyle increases the propensity to aging-related disease and premature death,” the authors write. “Inactivity may diminish life expectancy not only by predisposing to aging-related diseases but also because it may influence […]
Public release date: 28-Jan-2008 The annual number of Americans older than 65 newly diagnosed with diabetes increased by 23 percent between 1994 to 1995 and 2003 to 2004, according to a report in the January 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. “The prevalence of diabetes mellitus is increasing, in part because of population aging, but also in younger persons,” according to background information in the article. The high rate of existing diabetes also contributes to a high rate of diabetes-related complications and premature death. “Awareness of the importance of active monitoring and management […]
Public release date: 28-Jan-2008 Defense department funds study of nanotube-based drug made at Rice The Department of Defense has commissioned a nine-month study from Rice University chemists and scientists in the Texas Medical Center to determine whether a new drug based on carbon nanotubes can help prevent people from dying of acute radiation injury following radiation exposure. The new study was commissioned after preliminary tests found the drug was greater than 5,000 times more effective at reducing the effects of acute radiation injury than the most effective drugs currently available. “More than half of those who suffer acute radiation […]
Public release date: 28-Jan-2008 The Montreal Children’s Hospital of the MUHC recommends these products be used with extreme caution MONTREAL, Jan 28, 2008 — A new study, led by researchers at The Montreal Children’s Hospital (MCH) of the MUHC, has revealed that certain over-the-counter earwax softeners can cause severe inflammation and damage to the eardrum and inner ear. The results of the study, recently published in The Laryngoscope, suggest that use of these medications should be discouraged. “Because some of these products are readily available to the public without a consultation with or prescription from a […]
Public Release: 28-Jan-2008 Bethesda, MD (Jan. 28, 2008) – Patients with chronic hepatitis C (HCV) infection should not use marijuana (cannabis) daily, according to a study published in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute. Researchers found that HCV patients who used cannabis daily were at significantly higher risk of moderate to severe liver fibrosis, or tissue scarring. Additionally, patients with moderate to heavy alcohol use combined with regular cannabis use experienced an even greater risk of liver fibrosis. The recommendation to avoid cannabis is especially important in patients who are coinfected […]
Public release date: 29-Jan-2008 DALLAS, TX (Jan. 31, 2008) – New research suggests that women who take folic acid supplements for at least one year before they become pregnant can cut their risk of having a premature baby by half. Researchers at the 28th Annual Society for Maternal-Fetal Medicine (SMFM) meeting—The Pregnancy Meeting™—today unveiled a study linking pre-conceptional folate supplementation of at least one year to reduced early premature delivery rates of 50 to 70 percent, regardless of age, race or other factors. Of particular note is the drop in very early premature births, those babies who are […]
Public release date: 29-Jan-2008 Sex hormones circulating in the blood do not appear to be associated with prostate cancer risk, according to data from 18 prior studies. The analysis will be published online January 29 in the Journal of the National Cancer Institute. Having high levels of male sex hormones, known as androgens, has long been hypothesized as a risk factor for prostate cancer. Nearly two dozen prospective studies have examined the relationship between circulating sex hormones and prostate cancer risk, but the results have been inconsistent. Andrew Roddam, D.Phil., of the University of Oxford in England […]
Public release date: 29-Jan-2008 Microbiology Today: February 2008 issue Sequences of DNA in the human genome that originated from ancient viral infections have some surprising effects on our bodies and are even essential for a healthy pregnancy, according to an article in the February issue of Microbiology Today. Retrovirus infections represent the most intimate host-pathogen relationship. The virus inserts a copy of its genome into the DNA of the host cell, resulting in an irreversible, stable and sometimes lifelong infection. If a sperm or egg cell is infected, the virus DNA can be passed down generations, permanently fixed in the […]
Public release date: 30-Jan-2008 CINCINNATI—When it comes to Bisphenol A (BPA) exposure from polycarbonate plastic bottles, it’s not whether the container is new or old but the liquid’s temperature that has the most impact on how much BPA is released, according to University of Cincinnati (UC) scientists. Scott Belcher, PhD, and his team found when the same new and used polycarbonate drinking bottles were exposed to boiling hot water, BPA, an environmental estrogen, was released 55 times more rapidly than before exposure to hot water. “Inspired by questions from the climbing community, we went directly […]
Public release date: 30-Jan-2008 (An Extremely Flawed Study) February’s issue of Pediatrics offers another reason to rethink blaming the spike in autism diagnoses on thimerosal, a mercury-containing preservative routinely used in several childhood vaccines until the late ‘90s. New research from the University of Rochester suggests that infants’ bodies expel the thimerosal mercury much faster than originally thought – thereby leaving little chance for a progressive building up of the toxic metal. This debunks the great myth, believed by both parents and some pediatricians, that the gauntlet of thimerosal-containing shots many infants received in the 1990s – when […]
Public release date: 30-Jan-2008 Cadmium exposure is a known risk factor for prostate cancer, and a new University of Rochester study suggests that zinc may offer protection against cadmium. In an article published in the February 2008 journal, The Prostate, epidemiologist Edwin van Wijngaarden, Ph.D., reports that PSA levels were 22 percent higher among American men who had zinc levels below the median (less than 12.67 mg/daily) and cadmium levels above the median. (PSA is a protein produced by the cells of the prostate gland. The higher a man’s PSA level, the more likely cancer is present.) In […]
Public release date: 30-Jan-2008 Geneva, N.Y. – January 30, 2008 – Apples, bananas, and oranges are the most common fruits in both Western and Asian diets, and are important sources of vitamins, minerals, and fiber. A new study in the Journal of Food Science explores the additional health benefits of these fruits and reveals they also protect against neurodegenerative diseases, including Alzheimer’s Disease. Researchers at Cornell University investigated the effects of apple, banana, and orange extracts on neuron cells and found that the phenolic phytochemicals of the fruits prevented neurotoxicity on the cells. Among the three fruits, apples contained the […]
Public release date: 31-Jan-2008 Consumption of sugar sweetened soft drinks and fructose is strongly associated with an increased risk of gout in men, finds a study published on bmj.com today. Gout is a joint disease which causes extreme pain and swelling. It is most common in men aged 40 and older. It is caused by excess uric acid in the blood (hyperuricaemia) which leads to uric acid crystals collecting around the joints. In the United States, levels of gout have doubled over the last few decades, which coincided with a substantial increase in the consumption of soft drinks […]
Public release date: 31-Jan-2008 SEATTLE – Use of vitamin and mineral supplements among cancer survivors is widespread, despite inconclusive evidence that such use is beneficial, according to a comprehensive review of scientific literature conducted by researchers at Fred Hutchinson Cancer Research Center and published Feb. 1 in the Journal of Clinical Oncology. “Can vitamin and herbal supplements reduce the adverse effects of cancer treatment, decrease the risk of cancer recurrence or improve a patient’s chances of survival? We don’t really know. Research into these matters has been minimal,” said senior author Cornelia (Neli) Ulrich, Ph.D., an associate member of the […]
Public release date: 1-Feb-2008 A common flower that helps wipe out garden insects has also shown promise in eradicating stubborn warts, according to preliminary research presented by podiatrist Tracey Vlahovic at the American Academy of Dermatology’s Annual Meeting on Feb. 1. Vlahovic is assistant professor at Temple University School of Podiatric Medicine. Marigold Therapy, a line of creams, ointments, tinctures and oils developed and patented by chiropodist M. Taufiq Khan, contain extracts of several types of the marigold plant. Marigold has been used for nearly 30 years in the United Kingdom to treat a variety of foot issues, […]
Public Release: 1-Feb-2008 Simple urine test leads to more accurate diagnoses, fewer false-positive results PHILADELPHIA – An experimental biomarker test developed by researchers at the University of Michigan more accurately detects prostate cancer than any other screening method currently in use, according to a study published in the February 1 issue of Cancer Research, a journal of the American Association for Cancer Research. The researchers say a simple urine test that screens for the presence of four different RNA molecules accurately identified 80 percent of patients in a study who were later found to have prostate cancer, […]
Public release date: 1-Feb-2008 According to researchers at the University of Minnesota, the food industry has made progress in reducing the trans fat content in its products since a 2003 labeling mandate by the Food and Drug Administration, but consumers should still read labels to be certain the products are trans fat-free. The researchers sampled products at Minneapolis-area supermarket to assess levels of trans fat and saturated fat in margarines and butters; cookies and snack cakes; and savory snacks. The researchers also examined the cost of these now trans fat-free foods, because technologies to reduce or eliminate trans […]
Public release date: 1-Feb-2008 Mood disorders could be caused by a loss of our inherent, reflexive avoidance of aversive events, according to a study published in PLoS Computational Biology. Researchers from UCL in London and Columbia University in New York used computational modeling techniques to integrate what appeared to be blatant contradictions between serotonin’s roles in different states of health. Serotonin appears to be one of the major players in mood and a variety of other disorders. But exactly how remains an open question. Imagine walking past a dark alleyway in a dangerous part of some city; although […]
Public release date: 1-Feb-2008 Amid concern that people in the United States are consuming inadequate amounts of iodine, scientists in Texas have found that 53 percent of iodized salt samples contained less than the U.S. Food and Drug Administration (FDA) recommended level of this key nutrient. Iodized table salt is the main source of iodine for most individuals, they note in a study scheduled for the Feb. 15 issue of ACS’ Environmental Science & Technology, a semi-monthly journal. Purnendu K. Dasgupta and colleagues point out that iodine intake has been decreasing in the United States for decades. The […]
