Public release date: 14-Jun-2007 In this week’s BMJ, a senior doctor advises caution over the use of the antiviral drug oseltamivir (Tamiflu). His concern follows advice by the Japanese authorities in March 2007 against prescribing oseltamivir to adolescents after the separate suicides of two 14 year olds who jumped to their deaths while taking the drug. Before 2007, there had already been more than 100 reports of neuropsychiatric events (including delirium, convulsions, and encephalitis) with oseltamivir in children, almost entirely from Japan, which has the highest usage of oseltamivir worldwide. But a Food and Drug Administration (FDA) review concluded that […]
Public release date: 15-Jun-2007 Barcelona, Spain, Friday 15 June 2007: Breast feeding for a period of thirteen months or more has been shown to reduce the mother’s the risk of developing rheumatoid arthritis (RA), according to new data presented today at EULAR 2007, the Annual European Congress of Rheumatology in Barcelona, Spain. In the study, the longer the breast feeding period, the lower the mother’s risk of developing RA in later life. Comparable use of oral contraceptives (OCs) or hormone replacement therapy (HRT) did not show a significant effect on the risk of developing RA Lead researcher Dr Mitra Keshavarz, […]
People who drink coffee are less likely to develop an involuntary eye spasm called primary late onset blepharospasm, which makes them blink uncontrollably and can leave them effectively ‘blind’, according to a study published online ahead of print in the Journal of Neurology Neurosurgery and Psychiatry. Late onset blepharospasm is a dystonia in which the eyelid muscles contract uncontrollably; this starts as involuntary blinking but in extreme cases sufferers are rendered functionally blind despite normal vision because they are unable to prevent their eyes from clamping shut. They suggest that caffeine blocks adenosine receptors as has been proposed for its […]
In mice that were engineered with a genetic defect that caused prostate cancer, a diet high in omega-3 fatty acids beginning at birth reduced tumor growth, slowed disease progression and increased survival. The research is reported online today by the Journal of Clinical Investigation and will appear in the July 2 print issue. Mice with the tumor suppressor gene remained free of tumors and had 100 percent survival, regardless of diet. In mice with the gene defect, survival was 60 percent in animals on the high omega-3 diet, 10 percent in those on the low omega-3 diet and 0 percent […]
For immediate release: Thursday, June 21, 2007 Boston, MA — In a new, large-scale, prospective study exploring the link between levels of urate in the blood and risk of Parkinson’s disease, researchers from the Harvard School of Public Health (HSPH) have found that high levels of urate are strongly associated with a reduced risk of the disease. The findings were published online on June 20, 2007 in The American Journal of Epidemiology and will appear in an upcoming print issue of the journal Urate is a normal component of blood, and although high levels can lead to gout, urate might […]
Omega-3 supplements can, in certain cases, help combat the depression and agitation symptoms associated with Alzheimer’s disease, according to a clinical study conducted at the Swedish medical university Karolinska Institutet. There was no observable difference in therapeutic effect between the patients receiving the omega-3 and the placebo group. However, when the researchers took into account which of the patients carried the susceptibility gene APOE ?4 and which did not, an appreciable difference appeared. Carriers of the gene who had received active treatment responded positively to the omega-3 as regards agitation symptoms, while non-bearers of the gene showed an improvement […]
Public release date: 21-Jun-2007 K-State researchers are examining how nonsteroidal anti-inflammatory drugs, or NSAIDs, damage the tissue that lines the gastrointestinal tract. James Lillich, associate professor of clinical sciences, is leading the research. He said NSAIDs are some of the most commonly used prescription and over-the-counter drugs for relieving ailments from headaches to arthritis. NSAIDs work by blocking a type of enzyme called cyclooxygenase, or COX, which is needed for healthy cellular function. When tissue becomes inflamed, isoforms of the enzyme produce naturally occurring compounds called prostaglandins, which are responsible for the pain associated with inflammation. Although drugs inhibiting COX-2 […]
It has long been known that eating potatoes is good for bowel health, but new research suggests that they may also have a beneficial effect on the whole immune system. Especially if eaten cold or in a potato salad, Anne Pichon reports in Chemistry & Industry, the magazine of the SCI. The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect, a generally more healthy body, according to immunology expert Lena Ohman at the Department of Internal Medicine, Göteborg University, Sweden. A reduction in leucocyte levels of about 15% was observed in the RPS pigs. […]
Public release date: 24-Jun-2007 Omega-3 polyunsaturated fatty acids protect against the development and progression of retinopathy, a deterioration of the retina, in mice. This is the major finding of a study that appears in the July 2007 issue of the journal Nature Medicine. The study was a collaborative effort by researchers at Children’s Hospital Boston, the primary pediatric teaching affiliate of Harvard Medical School, Brigham and Women’s Hospital, Massachusetts General Hospital, the University of Goteborg in Sweden, and the National Eye Institute (NEI) and National Institute on Alcohol Abuse and Alcoholism (NIAAA) of the National Institutes of Health (NIH). The […]
Public release date: 25-Jun-2007 For more than 100 years, scientists have known that humans carry a rich ecosystem within their intestines. An astonishing number and variety of microbes, including as many as 400 species of bacteria, help humans digest food, mitigate disease, regulate fat storage, and even promote the formation of blood vessels. By applying sophisticated genetic analysis to samples of a year’s worth baby poop, Howard Hughes Medical Institute researchers have now developed a detailed picture of how these bacteria come and go in the intestinal tract during a child’s first year of life. The study, published June 25, […]
Public release date: 25-Jun-2007 The class of antidepressant medications known as selective serotonin reuptake inhibitors may be associated with an increased rate of bone loss in older men and women, according to two articles in the June 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Selective serotonin reuptake inhibitors (SSRIs) treat depression by inhibiting the protein that transports serotonin, a neurotransmitter involved in sleep and depression, according to background information in the articles. This protein has recently been discovered in bone as well, raising the possibility that SSRIs may affect bone density and the risk of […]
Public Release: 26-Jun-2007 Many cancer patients, suffering from fatigue and symptomatic anemia as side effects of their disease and its treatment, are prescribed ESAs—also known as EPO (epoetin alfa, or Procrit) and DARB (darbepoetin alfa, or Aranesp). New data—mostly from studies of off-label uses—on potentially dangerous side effects such as blood clots, and on survival rates, are prompting some scientists to recommend that the US Food and Drug Administration effectively curtail the use of ESAs. Adding fuel to this debate is the fact that the drugs are costly, and some critics have accused oncologists of overprescribing them, swayed by drug […]
Public Release: 26-Jun-2007 In research published in the July edition of the Journal of Epidemiology and Community Health, the York team led by Dr Simon Gilbody, concluded that there was a link between depression and low folate levels, following a review of 11 previous studies involving 15,315 participants. Dr Gilbody said: “Our study is unique in that for the first time all the relevant evidence in this controversial area has been brought together. Although the research does not prove that low folate causes depression, we can now be sure that the two are linked. Interestingly, there is also […]
Ballay Pharmaceuticals Inc. had a choice nine years ago: seek U.S. approval to sell a prescription decongestant or slip the drug on the market and hope regulators wouldn’t order it off. Almost 2 percent of U.S. prescriptions dispensed last year, or as many as 73 million, were for unapproved medicines such as Balamine, the FDA estimates. After years of paying little attention, the FDA now says it will step up efforts to get many of the drugs approved or taken off the market Physicians prescribe unapproved drugs and pharmacies sell them often without knowing their status. Insurance plans, including […]
Public release date: 11-Jun-2007 Infants lacking dog exposure have double asthma risk (NORTHBROOK, IL, JUNE 11, 2007) – New research indicates that children who receive antibiotics before their first birthday are significantly more likely to develop asthma by age 7. The study, published in the June issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians (ACCP), reports that children receiving antibiotics in the first year of life were at greater risk for developing asthma by age 7 than those not receiving antibiotics. The risk for asthma doubled in children receiving antibiotics for nonrespiratory […]
Public release date: 16-May-2007 A study to be published in an upcoming edition of the journal of Cardiovascular Toxicology reveals Pycnogenol natural pine bark extract from the French maritime pine tree, helps prevent damage that high blood pressure causes to the heart. The study demonstrates Pycnogenol counteracts the “wearing out” of the heart, which may aid the five million Americans living with heart failure. Previous studies have shown Pycnogenol supplementation to be associated with improved cardiovascular health, such as cholesterol reduction, blood pressure control and prevention of thrombosis. “This study provides evidence that oral administration of Pycnogenol reversed cardiovascular remodeling […]
Public release date: 8-Jun-2007 The four-year clinical trial included more than one thousand women over the age of 55 in one of three supplement groups: 1) calcium (1400-1500mg) plus vitamin D (1100 IU vitamin D) 2) calcium only (1400-1500 mg) or 3) a placebo. The researchers found that the risk of developing cancer was 60 percent lower for those who took calcium and vitamin D and 47 percent lower for those taking calcium alone, compared to the placebo. Fifty women developed nonskin cancer through the course of the four-year study, including breast, colon, lung and other cancers. When […]
Public release date: 7-Jun-2007 Researchers found that over the course of the seven-year study, patients visiting chiropractors and other CAM-oriented PCPs had 60 percent fewer hospitalizations, 62 percent fewer outpatient surgical cases, and 85 percent lower pharmaceutical costs when compared with total network HMO utilization rates and costs. The chiropractors and other CAM doctors treated and managed cases ranging from upper respiratory tract infections and allergies to headaches, orthopedic and other medical conditions Share this: Share on X (Opens in new window) X Share on WhatsApp (Opens in new window) WhatsApp Share on Facebook (Opens in new window) […]
Public release date: 11-Jun-2007 Two new studies find the uninsured and people with certain types of public health insurance are more likely to be diagnosed with more advanced cancer compared to those with private insurance. The studies, published in the July 15, 2007 issue of CANCER, a peer-reviewed journal of the American Cancer Society, find availability and type of health insurance predict disease severity in patients presenting with cancer of the oral cavity and breast in the United States. In their study of breast cancer and insurance status, Dr. Halpern and co-investigators found that uninsured and Medicaid insured patients were […]
Jun 8, 7:53 PM ET 2007 Many nutrition experts believe the number of malnourished Britons is closer to 4 million, about 6 percent of the population, than the government’s estimate of 2 million. There are no statistics on how many obese people may be malnourished, but doctors say they are seeing patients who are both overweight and malnourished. According to government statistics, 75 percent of Britons are overweight; more than one-fifth are obese. Usually, people with vitamin deficiencies have skin problems, a swollen thyroid or bleeding gums. In severe cases, malnourished people might also experience hair loss, muscle wasting, a […]
