Recent public health efforts have focused extensively on reducing the amount of formula babies are given in the hospital after birth. But in the first randomized trial of its kind, researchers at UC San Francisco have found that giving small amounts of formula in the first few days of life to infants experiencing high levels of early weight loss actually can increase the length of time their mothers end up breastfeeding. http://medicalxpress.com/news/2013-05-early-formula-mothers-breastfeed-longer.html Pediatrics Mon, 13 May 2013 00:10:06 EST news287589857 Increasing the number of hours of sleep adolescents get each night may reduce the prevalence of adolescent obesity, according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania. Results of the study show that fewer hours of sleep is associated with greater increases in adolescent body mass index (BMI) for participants between 14 and 18-years-old. The findings suggest that increasing sleep duration to 10 hours per day, especially for those in the upper half of the BMI distribution, could help to reduce the prevalence of adolescent obesity. Full results of the study are available online in the latest issue of Pediatrics. http://medicalxpress.com/news/2013-04-adolescent-obesity.html Overweight and Obesity Mon, 08 Apr 2013 12:38:25 EST news284643484 Stronger protections are needed to prevent people with HIV from also becoming infected with hepatitis, researchers argue in a new study led by Michigan State University. http://medicalxpress.com/news/2013-03-hiv-hepatitis-safeguards.html Diseases, Conditions, Syndromes Wed, 27 Mar 2013 12:16:17 EST news283605369 Peer support groups show promise for combating the debilitating stigma that surrounds epilepsy in much of the developing world, according to a new study led by a Michigan State University medical student. http://medicalxpress.com/news/2013-03-peer-epilepsy.html Neuroscience Mon, 11 Mar 2013 11:12:30 EST news282219142 Lance Waller, PhD, chair of Biostatistics and Bioinformatics at Emory's Rollins School of Public Health, will present preliminary work that explores relationships between high-levels of air pollution exposure and health effects at a press briefing hosted by the American Association for the Advancement of Science on February 17. http://medicalxpress.com/news/2013-02-explores-associations-air-pollution-health.html Health Sun, 17 Feb 2013 09:01:40 EST news280314064 Recently, large studies have identified some of the genetic basis for important common diseases such as heart disease and diabetes, but most of the genetic contribution to them remains undiscovered. Now researchers at the University of Massachusetts Amherst led by biostatistician Andrea Foulkes have applied sophisticated statistical tools to existing large databases to reveal substantial new information about genes that cause such conditions as high cholesterol linked to heart disease. http://medicalxpress.com/news/2013-02-biostatisticians-genes-linked-heart-disease.html Genetics Wed, 06 Feb 2013 17:00:01 EST news279387816 Among older women, getting a mammogram every two years was just as beneficial as getting a mammogram annually, and led to significantly fewer false positive results, according to a study led by UC San Francisco. http://medicalxpress.com/news/2013-02-mammogram-years-benefit-yearly-older.html Cancer Tue, 05 Feb 2013 10:30:39 EST news279282630 The rate of new HIV infections among men who have sex with men in England and Wales has remained unchanged over the past decade despite an almost four-fold increase in HIV testing, rising treatment coverage, and a 20 percent shortening of time-to-diagnosis, according to new research published Online First in the Lancet Infectious Diseases. http://medicalxpress.com/news/2013-01-hiv-men-sex-england-wales.html HIV & AIDS Thu, 31 Jan 2013 18:30:01 EST news278872420 A new method for detecting abnormalities in unborn children is providing physicians with more information to analyze the results than conventional, microscopic testing, according to two George Washington University researchers. http://medicalxpress.com/news/2012-12-prenatal-microarray-technology.html Genetics Thu, 06 Dec 2012 12:57:16 EST news274021003 Researchers at McMaster University have discovered new genetic evidence about why some people are happier than others. http://medicalxpress.com/news/2012-11-obese-happy-gene-common-perception.html Psychology & Psychiatry Tue, 20 Nov 2012 05:43:58 EST news272612627 (Medical Xpress)—New cases of C. difficile-associated diarrhea among hospitalized patients taking antibiotics can be reduced by two-thirds with the use of probiotics, according to new research published Monday in the Annals of Internal Medicine. http://medicalxpress.com/news/2012-11-probiotics-potential-minimize-difficile.html Diseases, Conditions, Syndromes Tue, 13 Nov 2012 06:05:25 EST news272009113 A new study shows that New Jersey's law requiring novice drivers to display a red decal on their license plates has prevented more than 1,600 crashes and helped police officers enforce regulations unique to new drivers. The first-in-the-nation decal provision went into effect in May 2010 as part of N.J.'s Graduated Driver Licensing (GDL) law. Nearly every state has a GDL law on the books, but "Kyleigh's Law," named for a teen driver killed in a 2006 N.J. crash, is the first one that requires drivers under age 21 to display their probationary status so that they are more visible to police. http://medicalxpress.com/news/2012-10-jersey-decal-young-drivers.html Health Tue, 23 Oct 2012 09:50:12 EST news270204008 Today researchers from The George Washington University published a study showing that breast cancer patients can reduce potentially dangerous delays in the identification of breast cancer with the assistance of patient navigation services. Patient navigation—a service that helps patients overcome barriers to getting health care, including setting up appointments, dealing with health insurance, and helping with fears about cancer—led to a nearly four-fold reduction in the time it took to diagnose a suspicious breast lump, the new study found. http://medicalxpress.com/news/2012-10-patient-faster-diagnosis-breast-cancer.html Cancer Mon, 08 Oct 2012 04:23:57 EST news268889028 In a recent study, investigators at Boston University Schools of Medicine (BUSM) and Public Health (BUSPH) identified a gene linking age-related cataracts and Alzheimer's disease.
