The study was among the first of its type to specifically measure a wide range of blood nutrient levels instead of basing findings on less precise data such as food questionnaires, and found positive effects of high levels of vitamins B, C, D, E and the healthy oils most usually found in fish........ ]]> http://medicineworld.org/stories/lead/12-2011/new-way-to-ensure-effectiveness-of-tb-treatment.html http://medicineworld.org/stories/lead/12-2011/new-way-to-ensure-effectiveness-of-tb-treatment.html Sat, 21 Jan 2012 00:41:24 GMT A UT Southwestern Medical Center study using a sophisticated "glass mouse" research model has observed that multidrug-resistant tuberculosis (TB) is more likely caused in patients by speedy drug metabolism rather than inconsistent doses, as is widely believed. If the study published in The Journal of Infectious Diseases is borne out in future investigations, it may lead to better ways to treat one of the world's major infectious diseases. Health workers worldwide currently are mandatory to witness each administration of the combination of drugs during months of treatment........ ]]> http://medicineworld.org/stories/lead/12-2011/read-infant-acetaminophen-labels-carefully.html http://medicineworld.org/stories/lead/12-2011/read-infant-acetaminophen-labels-carefully.html Sat, 21 Jan 2012 00:41:24 GMT Acetaminophen is one of the most usually used pain and fever relievers for infants and children and is safe and effective when used as directed. However, with recent dosing changes to liquid acetaminophen products for infants, the FDA last week issued a press release urging parents to know the concentration and read the label as the new, less concentrated form of the popular pain reliever arrives on store shelves........ ]]> http://medicineworld.org/stories/lead/12-2011/turn-down-the-ipod-to-save-your-hearing.html http://medicineworld.org/stories/lead/12-2011/turn-down-the-ipod-to-save-your-hearing.html Sat, 21 Jan 2012 00:41:24 GMT Today's ubiquitous MP3 players permit users to listen to crystal-clear tunes at high volume for hours on end - a marked improvement on the days of the Walkman. But as per Tel Aviv University research, these advances have also turned personal listening devices into a serious health hazard, with teenagers as the most at-risk group........ ]]> http://medicineworld.org/stories/lead/11-2011/bridge-trial-results-presented-at-tct.html http://medicineworld.org/stories/lead/11-2011/bridge-trial-results-presented-at-tct.html Sat, 21 Jan 2012 00:41:24 GMT Late breaking clinical trial results from testing of cangrelor, an investigational intravenous antiplatelet, showed patients can be "bridged" from the time that their physicians stop their oral antiplatelet drugs until they undergo cardiac surgery. Study results demonstrated cangrelor maintained target levels of platelet inhibition known to be linked to a low risk of thrombotic events, such as stent thrombosis, vs. placebo. The BRIDGE Trial results were presented here today at the Cardiovascular Research Foundation (CRF) annual Transcatheter Cardiovascular Therapeutics (TCT) conference........ ]]> http://medicineworld.org/stories/lead/10-2011/morning-people-and-night-owls.html http://medicineworld.org/stories/lead/10-2011/morning-people-and-night-owls.html Sat, 21 Jan 2012 00:41:24 GMT It's true. The daily grind dealing with bosses, colleagues and repetitive work sours people's moods. But scientists say the cause appears to be something more than the work itself; people's biological clocks appears to be sending a message. "Though it might seem intuitive to suggest that the decrease in mood level during the midday hours is a result of workday-related stress," said Scott Golder, lead researcher for a study appearing today in the journal Science, "it turns out we see the same rhythmic shape on the weekends, when people typically are not working. This suggests to us that something more enduring is going on, such as the effect of biological processes and sleep"........ ]]> http://medicineworld.org/stories/lead/10-2011/quality-measure-for-asthma.html http://medicineworld.org/stories/lead/10-2011/quality-measure-for-asthma.html Sat, 21 Jan 2012 00:41:24 GMT Scientists studying the first national quality measure for hospitalized children have observed that no matter how strictly a health care institution followed the criteria, it had no actual impact on patient outcomes. The researchers examined 30 hospitals with 37,267 children admitted for asthma from 2008 to 2010 and discovered that the quality of discharge planning made no difference to the rate of return to the hospital for another asthma attack in 7, 30 or 90 days........ ]]> http://medicineworld.org/stories/lead/9-2011/new-half-match-bone-marrow-transplant.html http://medicineworld.org/stories/lead/9-2011/new-half-match-bone-marrow-transplant.html Sat, 21 Jan 2012 00:41:24 GMT Half-matched bone marrow or stem cell transplants for blood cancer patients have typically been linked to disappointing clinical outcomes. However, a clinical trial conducted at the Kimmel Cancer Center at Jefferson testing its unique, two-step half-match procedure has produced some promising results: the probability of overall survival was 45 percent in all patients after three years and 75 percent in patients who were in remission at the time of the transplant........ ]]> http://medicineworld.org/stories/lead/8-2011/good-prion-like-proteins-boost-immune-response.html http://medicineworld.org/stories/lead/8-2011/good-prion-like-proteins-boost-immune-response.html Sat, 21 Jan 2012 00:41:24 GMT A person's ability to battle viruses at the cellular level remarkably resembles the way deadly infectious agents called prions misfold and cluster native proteins to cause disease, UT Southwestern Medical Center scientists report. This study marks the first discovery of so-called "good" prion-like proteins in human cells and the first to find such proteins involved in innate immunity: the way the body recognizes and responds to threats from viruses or other external agents, said Dr. Zhijian "James" Chen, professor of molecular biology and senior author of the study in the Aug. 5 print edition of the journal Cell....... ]]> http://medicineworld.org/stories/lead/8-2011/why-knee-osteoarthritis-afflicts-more-women.html http://medicineworld.org/stories/lead/8-2011/why-knee-osteoarthritis-afflicts-more-women.html Sat, 21 Jan 2012 00:41:24 GMT A Mayo Clinic orthopedic surgeon suspects that the nagging pain and inflammation that women can experience in their knees appears to be different from what men encounter, and she has been chosen to lead a novel U.S.-Canadian study to explore the question. The Society for Women's Health Research (SWHR) and its Interdisciplinary Studies in Sex-Differences (ISIS) Network on Musculoskeletal Health has awarded a group of scientists a $127,000 grant to lead a pilot project to understand whether biological differences between men and women affect the incidence and severity of knee osteoarthritis. Mary I. O'Connor, M.D., chair of the Department of Orthopedic Surgery at Mayo Clinic's campus in Florida, will be the study's principal investigator........ ]]> http://medicineworld.org/stories/lead/8-2011/mold-exposure-during-infancy.html http://medicineworld.org/stories/lead/8-2011/mold-exposure-during-infancy.html Sat, 21 Jan 2012 00:41:24 GMT Infants who live in "moldy" homes are three times more likely to develop asthma by age 7�an age that children can be accurately diagnosed with the condition. Study results are reported in the recent issue of Annals of Allergy, Asthma and Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI)........ ]]> http://medicineworld.org/stories/lead/8-2011/4-times-more-on-health-insurance-costs.html http://medicineworld.org/stories/lead/8-2011/4-times-more-on-health-insurance-costs.html Sat, 21 Jan 2012 00:41:24 GMT U.S. physicians spend nearly $61,000 more than their Canadian counterparts each year on administrative expenses correlation to health insurance, as per a newly released study by scientists at Cornell University and the University of Toronto. The study, reported in the recent issue of the journal Health Affairs, observed that per-doctor costs in the U.S. averaged $82,975 annually, while Ontario-based physicians averaged $22,205 � primarily because Canada's single-payer health care system is simpler........ ]]>
