Public release date: 22-Oct-2007 DALLAS, Oct. 23 – A new global study revealed that 40 percent of men and 30 percent of women are overweight, while 24 percent of men and 27 percent of women are obese, researchers reported in Circulation: Journal of the American Heart Association. In the study, 168,159 people (69,409 men, 98,750 women) from 18 to 80 years old (average age 48) in 63 countries across five continents were evaluated by their primary care physicians “This is the largest study to assess the frequency of adiposity (body fat) in the clinic, providing a snapshot of patients worldwide,” […]
Public release date: 22-Oct-2007 Americans are less willing to pay more for healthy dishes, less knowledgeable about healthy menu items, and more likely to consider healthy items bland tasting, finds a Temple University analysis Americans also reported eating out approximately five times a week in 2006. Fast-food restaurants were the most popular eating establishments for breakfast and lunch, while fast-food and casual dining were the two most popular places for dinner. Ease, convenience and cost were among the top reasons respondents ordered value/combo meals at fast-food restaurants. In 2006, about 50 percent of respondents strongly agreed that they would be […]
Public release date: 22-Oct-2007 XDR TB in South Africa traced to lack of drug susceptibility testing In South Africa, the 2001 implementation of the World Health Organization’s anti-tuberculosis program may have inadvertently helped to create a new strain of extensively drug-resistant tuberculosis (XDR TB). In a new study published in the December 1 issue of Clinical Infectious Diseases, currently available online, researchers tracked the developing drug resistance of one particular strain of Mycobacterium tuberculosis over 12 years. They found that at the time of the 2001 adoption of the DOT+ strategy for multi-drug resistant strains, the strain was already resistant […]
Public release date: 22-Oct-2007 A team of Johns Hopkins scientists reports in this week’s issue of the Proceedings of the National Academy of Sciences that humans can be protected against the damaging effects of ultraviolet (UV) radiation — the most abundant cancer-causing agent in our environment — by topical application of an extract of broccoli sprouts. The results in human volunteers, backed by parallel evidence obtained in mice, show that the degree of skin redness (erythema) caused by UV rays, which is an accurate index of the inflammation and cell damage caused by UV radiation, is markedly reduced in extract-treated […]
Public release date: 22-Oct-2007 BOSTON — When elderly nursing home residents contract pneumonia, it is a blow to their already fragile health. Simin Nikbin Meydani, DVM, PhD of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University and colleagues report that maintaining normal serum zinc concentration in the blood may help reduce the risk of pneumonia development in that population. “Based on our data, it appears that daily zinc intake can help nursing home residents who are susceptible to pneumonia, especially those with low serum zinc concentrations in their blood,” says Meydani, corresponding author and director […]
Public release date: 22-Oct-2007 Just three months of daily, vigorous physical activity in overweight children improves their thinking and reduces their diabetes risk, researchers say. “Is exercise a magic wand that turns them into lean, healthy kids? No. They are still overweight but less so, with less fat, a healthier metabolism and an improved ability to handle life,” says Dr. Catherine Davis, clinical health psychologist at the Medical College of Georgia and lead investigator. Looking at the children’s insulin resistance, a precursor of type 2 diabetes in which it takes more insulin to convert glucose into energy, researchers found levels […]
Public release date: 24-Oct-2007 New research investigates a possible link between iron deficiency in women and idiopathic cough. Italian researchers evaluated 16 healthy, non-smoking women, all of whom had normal lung function tests. All of the women suffered from chronic idiopathic cough and were iron deficient. Researchers found that these symptoms were strongly associated with extrathoracic airway hyperresponsiveness in all of the participants.

Public release date: 24-Oct-2007 Researchers from the University of Pittsburgh School of Medicine have released a new study, examining the relationship between sleep fragmentation and lipid profiles. Both normal and overweight individuals underwent three nights of testing, which included polysomnography and blood testing to determine total cholesterol and triglycerides. Results showed that moderate sleep fragmentation was associated with reduced cholesterol in the overweight participants only.

Public release date: 24-Oct-2007 A new study evaluates the roles of gender and body measurements in the severity of obstructive sleep apnea (OSA) and continuous positive airway pressure (CPAP) requirements. Researchers from Baylor College of Medicine and The Methodist Hospital, in Texas, took multiple body measurements from 144 men and women with OSA. They found that patients’ neck circumference, rather than their body mass index (BMI), was more predictive of OSA severity, especially in women. Both neck circumference and BMI correlated to CPAP requirements. Share this: Share on X (Opens in new window) X Share on WhatsApp (Opens in new […]
Public release date: 24-Oct-2007 New research shows that antioxidants—vitamins A, C, and E—may help improve lung function in people who smoke. Researchers from Bangladesh compared the lung function of 200 healthy male smokers who took one vitamin—A, C, or E— or all three in combination for 2 months. Results showed that patients taking vitamins, improved their lung function after 2 months, with those taking all three vitamins in combination experiencing the largest improvement in lung function. The study also found that when vitamin supplementation was ceased, smokers’ lung function decreased, leading researchers to conclude that the beneficial effects of vitamins […]
Public release date: 24-Oct-2007 When people living in many parts of the world move their clocks forward one hour in the spring in observance of daylight saving time (DST), their bodies’ internal, daily rhythms don’t adjust with them, reports a new study appearing online on October 25th in Current Biology, a publication of Cell Press. The finding suggests that this regular time change—practiced by a quarter of the human population—represents a significant seasonal disruption, raising the possibility that DST may have unintended effects on other aspects of human physiology, according to the researchers “When we implement small changes into a […]
Public release date: 24-Oct-2007 Inhaled depleted uranium (DU) oxide aerosols are recognised as a distinct human health hazard and DU has been suggested to be responsible in part for illness in both military and civilian populations that may have been exposed. The issue has been the subject of investigations by the Royal Society (UK), the National Academy of Science (US) and other bodies, but studies of individuals who have been clearly exposed to environmental contamination are lacking. Professor Parrish commented: “Our objective was to develop a high sensitivity method of EU detection in urine, using MC-ICP mass spectrometry that would […]
Public Release: 24-Oct-2007 – It used to be dogma that the brain was shut away from the actions of the immune system, shielded from the outside forces of nature. But that’s not how it is at all. In fact, thanks to the scientific detective work of Kevin Tracey, MD, it turns out that the brain talks directly to the immune system, sending commands that control the body’s inflammatory response to infection and autoimmune diseases. Understanding the intimate relationship is leading to a novel way to treat diseases triggered by a dangerous inflammatory response. Dr. Tracey, director and chief executive of […]
Public release date: 24-Oct-2007 “AT THIS point I’ll try anything I can to have a child,” says Emma*, a 38-year-old teacher from London. Emma faces a similar problem to many women: her ovaries produce too few ripe eggs for doctors to extract and use for in-vitro fertilisation (IVF). She is also one of a number of women undergoing IVF who is self-medicating with a supplement called dehydroepiandrosterone (DHEA) in an attempt to beat the biological clock Researchers at the Center for Human Reproduction in New York began exploring the effects of DHEA in 2004, when they learned that an older […]
Public release date: 24-Oct-2007 CLEVELAND – Scientists at Case Western Reserve University’s School of Medicine have published in the Journal of Inflammation a remarkable discovery with a natural product derived from the Amazon rainforest. The discovery’s unique actions suggest a broad set of applications in various joint, skin and gastrointestinal diseases, including osteoarthritis and irritable bowel syndrome The publication revealed that Progrado®, an extract from a rainforest tree called Croton palanostigma, was a remarkably potent antioxidant and prevented the destruction of human cartilage by molecular s scissors called matrix metalloproteinases (MMPs). According to the researchers, these enzymes cut collagen, which […]
Public Release: 25-Oct-2007 Boulder, CO, USA – French clay that kills several kinds of disease-causing bacteria is at the forefront of new research into age-old, nearly forgotten, but surprisingly potent cures. Among the malevolent bacteria that a French clay has been shown to fight is a “flesh-eating” bug (M. ulcerans) on the rise in Africa and the germ called MRSA, which was blamed for the recent deaths of two children in Virginia and Mississippi In laboratory tests at ASU’s Biodesign Institute, co-PI Haydel, an assistant professor in the School of Life Sciences, showed that one clay killed bacteria responsible for […]
Public release date: 26-Oct-2007 For the first time, a new screening method shows promise for identifying new human tumor viruses, as well as determining which cancers are caused by infection and which are not. The researchers report their findings in the October 2007 issue of the Journal of Virology. Statistics now show that infection contributes to over 20% of human cancers worldwide. Presently, the list of confirmed carcinogenic infectious agents is short, however studies suggest that new infectious agents yet to be identified contribute to a wide range of diseases, including cancers. A major obstacle in new pathogen discovery is […]
Public release date: 28-Oct-2007 Exercise may reduce, and even reverse, bone loss caused by hormone and radiation therapies used in the treatment of localized prostate cancer, thereby decreasing the potential risk of bone fractures and improving quality of life for these men, according to a study presented on October 28, 2007, at the American Society for Therapeutic Radiology and Oncology’s 49th Annual Meeting in Los Angeles. Men with localized prostate cancer frequently receive radiation therapy followed by months of hormone therapy to treat their cancer. Radiation is used to kill the cancer cells, while hormone therapy decreases testosterone and estrogen […]
Public release date: 29-Oct-2007 Life expectancy for RA patients has not improved over the past 4 decades, finds Mayo Clinic study, indicating urgent need for improved intervention strategies Researchers compared the survival rates of patients diagnosed with RA in 5 time periods: 1955-1964, 1965-1974, 1975-1984, 1985-1994, and 1995-2000 using Cox regression models, adjusting for age and sex. In the 5 time periods, there was no significant difference in survival rates for RA subjects—which also means no significant gains in longevity. “We found no evidence indicating that RA subjects experienced improvements in survival over the last 4-5 decades” states the study’s […]
Public release date: 29-Oct-2007 New York, October 29, 2007 — Another disease can be added to the list of smoking-related disorders — psoriasis. Researchers have found that smoking increases the risk of developing psoriasis, heavier smoking increases the risk further, and the risk decreases only slowly after quitting. Investigators from the Massachusetts General Hospital, Brigham and Women’s Hospital, the Harvard School of Public Health, all in Boston, USA, and Vancouver General Hospital, Vancouver, BC, Canada, have published the results in the November 2007 issue of The American Journal of Medicine. Compared with women who never smoked, the risk of psoriasis […]
