More than 1,500 pedestrians were estimated to be treated in emergency rooms in 2010 for injuries related to using a cell phone while walking, according to a new nationwide study. http://medicalxpress.com/news/2013-06-distracted-injuries-soar-pedestrians.html Health Wed, 19 Jun 2013 10:06:06 EST news290855063 Despite the fact that the incidence of cancer is many fold higher in persons over 65 years of age, we still have an inadequate understanding on how best to treat these older cancer patients. Furthermore, even though elderly patients are occasionally included in clinical trials, those elderly patients who are eventually included are mostly 'healthy' (fit) elderly patients. Thus, the broader elderly patient population is not well represented in clinical trials. The EORTC Cancer in the Elderly Task Force is now starting a new phase 2 trial in precisely this group of patients: EORTC 75111 – 10114 for non-fit elderly patients with HER-2 positive metastatic breast cancer. http://medicalxpress.com/news/2013-06-eortc-elderly-patients-her-positive.html Cancer Wed, 19 Jun 2013 10:00:15 EST news290854794 For years, Alzheimer's researchers have focused on two proteins that accumulate in the brains of people with Alzheimer's and may contribute to the disease: plaques made up of the protein amyloid-beta, and tangles of another protein, called tau. http://medicalxpress.com/news/2013-06-alzheimer-interaction-proteins-brain.html Alzheimer's disease & dementia Wed, 19 Jun 2013 09:25:13 EST news290852704 The age at which many children in the U.S. take their first sip of alcohol is surprisingly young, finds a new study in the Journal of Adolescent Health. http://medicalxpress.com/news/2013-06-alcohol-grade.html Health Wed, 19 Jun 2013 09:20:01 EST news290851533 For years, the mantra of neurologists treating stroke victims has been "time equals brain."

As unlikely as it may seem, those compounds are sparking optimism as potential treatments for ovarian and breast cancers driven by a mutation in BRCA, a gene that made headlines when actress Angelina Jolie revealed she carries the mutation. The compounds, termed PARP inhibitors, are the topic of the cover story in the current edition of Chemical & Engineering News.

Persons with pathological narcissism on the one hand suffer from feelings of inferiority, while on the other hand projecting themselves to the world as arrogant, disparaging and self-absorbed. One of the key features of a narcissistic personality disorder is the lack of empathy.

The negative effects of that abuse and the adverse impact on patient care are also well-documented. Now, a study of newly licensed registered nurses (NLRNs) finds that nurses who are verbally abused by nursing colleagues report lower job satisfaction, unfavorable perceptions of their work environment, and greater intent to leave their current job. The study, conducted by the RN Work Project, a program of the Robert Wood Johnson Foundation, was published online in the Journal of Nursing Scholarship. http://medicalxpress.com/news/2013-06-nurses-abused-colleagues-commitment-employer.html Health Wed, 19 Jun 2013 06:20:23 EST news290841616
