In the United States, pedestrians make up 12 percent of deaths from traffic collisions. According to a newly published study, male pedestrians struck by vehicles are more than twice as likely to die as their female counterparts. http://medicalxpress.com/news/2012-12-males-vehicles-die.html Health Tue, 11 Dec 2012 08:17:18 EST news274436097 Johns Hopkins scientists have found a surprising mechanism that gives male sex hormones like testosterone control over the gender-specific absence or presence of mammary gland nerves that sense the amount of milk available in breast milk ducts. http://medicalxpress.com/news/2012-12-male-hormones-differences-mammary-gland.html Medical research Thu, 06 Dec 2012 14:00:34 EST news274021844 A new Boston University School of Medicine (BUSM) study has found that improving Human papillomavirus (HPV) vaccination rates in black women may require culturally sensitive approaches that address ethnic-specific barriers.

The first findings reveal that people diagnosed with cancer, diabetes, respiratory or cardiovascular disease report similar mental health scores to those without physical illness. The survey's findings suggest that those people who may not be able to function well physically because of an illness do not necessarily suffer problems with their mental health - for example with their concentration, confidence and feelings of strain. http://medicalxpress.com/news/2011-07-resilience-long-term-ill.html Health Mon, 11 Jul 2011 10:12:36 EST news229597942
