Analyzing data from interviews with 262 mothers of African-American children with asthma - a population disproportionately affected by this inflammatory airway disorder - the Hopkins researchers observed that children whose mothers had more depressive symptoms had more frequent asthma symptoms during the six-months of the study. On the other hand, children whose mothers reported fewer depressive symptoms had less frequent asthma symptoms........ ]]> http://medicineworld.org/stories/lead/11-2009/a-new-weapon-against-allergies-and-asthma.html http://medicineworld.org/stories/lead/11-2009/a-new-weapon-against-allergies-and-asthma.html Fri, 20 Nov 2009 14:48:07 GMT Researchers at Johns Hopkins and their colleagues have developed sugar-coated polymer strands that selectively kill off cells involved in triggering aggressive allergy and asthma attacks. Their advance is a significant step toward crafting pharmaceuticals to fight these often life-endangering conditions in a new way........ ]]> http://medicineworld.org/stories/lead/11-2009/supplying-prescriptions-as-three-month-supply.html http://medicineworld.org/stories/lead/11-2009/supplying-prescriptions-as-three-month-supply.html Fri, 20 Nov 2009 14:48:07 GMT Purchasing prescription drugs in a three-month supply rather than a one-month supply has long been regarded as a way to reduce the cost of drugs for patients and third-party payers. New research from the University of Chicago quantifies the savings for the first time. An analysis of 26,852 prescriptions filled for 395 different drugs from 2000-2005 showed that patients who purchased their drugs in three-month supplies rather than with one-month supplies saved on average 29% in out-of-pocket costs. After factoring in third-party payers, including Medicare, Medicaid and insurance companies, total savings averaged 18%........ ]]> http://medicineworld.org/stories/lead/11-2009/transcendental-meditation-for-college-students.html http://medicineworld.org/stories/lead/11-2009/transcendental-meditation-for-college-students.html Fri, 20 Nov 2009 14:48:07 GMT The Transcendental Meditation technique appears to be an effective method to reduce blood pressure, anxiety, depression, and anger among at-risk college students, as per a newly released study to be reported in the American Journal of Hypertension, December 2009. "The Transcendental Meditation Program, a widely-used standardized program to reduce stress, showed significant decreases in blood pressure and improved mental health in young adults at risk for hypertension," said David Haaga, PhD, co-author of the study and professor of psychology at American University in Washington, D.C........ ]]> http://medicineworld.org/stories/lead/11-2009/morphine-may-stimulate-cancer-growth.html http://medicineworld.org/stories/lead/11-2009/morphine-may-stimulate-cancer-growth.html Fri, 20 Nov 2009 14:48:07 GMT Eventhough morphine has been the gold-standard therapy for postoperative and chronic cancer pain for two centuries, a growing body of evidence is showing that opiate-based painkillers can stimulate the growth and spread of cancer cells. Two new studies advance that argument and demonstrate how shielding lung cancer cells from opiates reduces cell proliferation, invasion and migration in both cell-culture and mouse models........ ]]> http://medicineworld.org/stories/lead/11-2009/vitamin-a-deficiency-in-women.html http://medicineworld.org/stories/lead/11-2009/vitamin-a-deficiency-in-women.html Fri, 20 Nov 2009 14:48:07 GMT Almost half of UK women could be suffering from a lack of vitamin A due to a previously undiscovered genetic variation, researchers at Newcastle University have found. The team, led by Dr Georg Lietz, has shown that almost 50 per cent of women have a genetic variation which reduces their ability to produce sufficient amounts of vitamin A from beta-carotene........ ]]> http://medicineworld.org/stories/lead/11-2009/smoking-and-seizure.html http://medicineworld.org/stories/lead/11-2009/smoking-and-seizure.html Fri, 20 Nov 2009 14:48:07 GMT A recent study determined there is a significant risk of seizure for individuals who currently smoke cigarettes. Boston-based scientists from Brigham and Women's Hospital and Harvard Medical School also observed that long-term, moderate intake of caffeine or alcohol does not increase the chance of having a seizure or developing epilepsy. This is the first prospective study to examine the potential risks linked to cigarette smoking, caffeine intake, and alcohol consumption as they independently relate to epilepsy. Full findings of this study are currently available online and will appear in the February 2010 issue of Epilepsia, a journal published by Wiley-Blackwell on behalf of the International League Against Epilepsy........ ]]> http://medicineworld.org/stories/lead/11-2009/liver-protective-effects-of-green-tea.html http://medicineworld.org/stories/lead/11-2009/liver-protective-effects-of-green-tea.html Fri, 20 Nov 2009 14:48:07 GMT Several studies have shown that lipid peroxidation stimulates collagen production in fibroblasts and hepatic stellate cells (HSC), and plays an important role in the development of liver fibrosis. Hepatoprotective effects of green tea against carbon tetrachloride, cholestasis and alcohol induced liver fibrosis were reported in many studies. However, the hepatoprotective effect of green tea in dimethylnitrosamine (DMN)-induced models has not been studied........ ]]> http://medicineworld.org/stories/lead/11-2009/activation-of-immune-system-in-schizophrenia.html http://medicineworld.org/stories/lead/11-2009/activation-of-immune-system-in-schizophrenia.html Fri, 20 Nov 2009 14:48:07 GMT Scientists at the Swedish medical university Karolinska Institutet have discovered that patients with recent-onset schizophrenia have higher levels of inflammatory substances in their brains. Their findings offer hope of being able to treat schizophrenia with drugs that affect the immune system. The causes of schizophrenia are largely unknown, and this hinders the development of effective therapys. One theory is that infections caught early on in life might increase the risk of developing schizophrenia, but to date any direct evidence of this has not been forthcoming........ ]]> http://medicineworld.org/stories/lead/11-2009/why-hepatitis-is-harder-on-men.html http://medicineworld.org/stories/lead/11-2009/why-hepatitis-is-harder-on-men.html Fri, 20 Nov 2009 14:48:07 GMT Researchers in China are reporting discovery of unusual liver proteins, found only in males, that may help explain the long-standing mystery of why the hepatitis B virus (HBV) sexually discriminates -- hitting men harder than women. Their study has been published online in ACS' Journal of Proteome Research, a monthly publication........ ]]> http://medicineworld.org/stories/lead/11-2009/as-women-age.html http://medicineworld.org/stories/lead/11-2009/as-women-age.html Fri, 20 Nov 2009 14:48:07 GMT In a step toward using human saliva to tell whether those stiff joints, memory lapses, and other telltale signs of aging are normal or red flags for disease, researchers are describing how the protein content of women's saliva change with advancing age. The discovery could lead to a simple, noninvasive test for better diagnosing and treating certain age-related diseases in women, they suggest in a report in ACS' Journal of Proteome Research, a monthly publication. These diseases include lupus, Sjgrens syndrome (linked to dry mouth and dry eye), and other immune-related disorders that affect millions of women worldwide, often at higher rates than in men........ ]]> http://medicineworld.org/stories/lead/11-2009/catching-circulating-cancer-cells.html http://medicineworld.org/stories/lead/11-2009/catching-circulating-cancer-cells.html Fri, 20 Nov 2009 14:48:07 GMT Just as fly paper captures insects, an innovative new device with nano-sized features developed by scientists at UCLA is able to grab cancer cells in the blood that have broken off from a tumor. These cells, known as circulating tumor cells, or CTCs, can provide critical information for examining and diagnosing cancer metastasis, determining patient prognosis, and monitoring the effectiveness of therapies........ ]]> http://medicineworld.org/stories/lead/11-2009/brains-ability-to-reorganize.html http://medicineworld.org/stories/lead/11-2009/brains-ability-to-reorganize.html Fri, 20 Nov 2009 14:48:07 GMT Visually impaired people appear to be fearless, navigating busy sidewalks and crosswalks, safely finding their way using nothing more than a cane as a guide. The reason they can do this, scientists suggest, is that in at least some circumstances, blindness can heighten other senses, helping individuals adapt........ ]]> http://medicineworld.org/stories/lead/11-2009/hazards-of-outdoor-second-hand-smoke.html http://medicineworld.org/stories/lead/11-2009/hazards-of-outdoor-second-hand-smoke.html Fri, 20 Nov 2009 14:48:07 GMT Indoor smoking bans have forced smokers at bars and restaurants onto outdoor patios, but a new University of Georgia study in collaboration with the Centers for Disease Control and Prevention suggests that these outdoor smoking areas might be creating a new health hazard. The study, believed to be the first to assess levels of a nicotine byproduct known as cotinine in nonsmokers exposed to second-hand smoke outdoors, found levels up to 162 percent greater than in the control group. The results appear in the recent issue of the Journal of Occupational and Environmental Hygiene....... ]]> http://medicineworld.org/stories/lead/11-2009/a-powerful-combination-punch-against-breast-cancer.html http://medicineworld.org/stories/lead/11-2009/a-powerful-combination-punch-against-breast-cancer.html Fri, 20 Nov 2009 14:48:07 GMT A powerful new breast cancer therapy could result from packaging one of the newer drugs that inhibits cancer's hallmark wild growth with another that blocks a primordial survival technique in which the cancer cell eats part of itself, scientists say. While they are powerful killers of some breast cancer cells, new drugs called histone deacetylase inhibitors, or HDAC inhibitors, also increase self-digestion, or autophagy, in surviving, mega-stressed cells, Medical College of Georgia Cancer Center scientists reported during the Molecular Targets and Cancer Therapeutics International Conference this week in Boston. The conference is sponsored by the American Association for Cancer Research, the National Cancer Institute and the European Organisation for Research and Treatment of Cancer........ ]]>
