On the other hand, non-melancholic depressive symptoms are associated with an increased risk for the metabolic syndrome. Based on these new observations, melancholic and non-melancholic depression may be separate depressive subtypes with different etiologies in terms of proinflammation and diet. The study was the first to look at these depressive sub-types separately. http://medicalxpress.com/news/2012-11-lack-nutrients-metabolic-syndrome-linked.html Psychology & Psychiatry Mon, 26 Nov 2012 13:36:12 EST news273159329 We've all been warned not to "judge a book by its cover," but inevitably we do it anyway.

The notion that the field discriminates against and is skewed toward a liberal political perspective is worthy of concern; scholars, both within and outside the field, have offered various solutions to this diversity problem. http://medicalxpress.com/news/2012-09-social-psychologists-espouse-tolerance-diversitydo.html Psychology & Psychiatry Thu, 06 Sep 2012 14:59:58 EST news266162391 The number of people with Ebola, a rare haemorrhagic disease, in northeastern Democratic Republic of Congo has tripled since mid-August, the World Health Organisation said Tuesday, after 14 patients died in two weeks. http://medicalxpress.com/news/2012-09-ebola-caseload-soars-eastern-dr.html Diseases, Conditions, Syndromes Tue, 04 Sep 2012 13:50:02 EST news265983897 (HealthDay) -- For men with clinically localized prostate cancer, radical prostatectomy does not significantly reduce all-cause or prostate-cancer mortality compared with observation through 12 years of follow-up, according to a study published in the July 19 issue of the New England Journal of Medicine. http://medicalxpress.com/news/2012-07-radical-prostatectomy-doesnt-mortality.html Cancer Thu, 19 Jul 2012 07:10:01 EST news261892989 Nobody wins when patients stay in the hospital unnecessarily, so the federal government in recent years has pushed hospitals to be careful about admitting Medicare recipients as inpatients. The apparent result is that more patients are being "held for observation" instead, according to a new study by Brown University gerontologists. While the shift in how hospitals care for elderly patients in the emergency department may reduce costs to Medicare, it can also increase out-of-pocket expenditures for patients. http://medicalxpress.com/news/2012-06-pressure-medicare-hospitals-seniors.html Health Mon, 04 Jun 2012 16:00:45 EST news258037074 Herpes and other viruses that attack the nervous system may thrive by disrupting cell function in order to hijack a neuron's internal transportation network and spread to other cells. http://medicalxpress.com/news/2012-05-nervous-viruses-sabotage-cell-hijack.html Medical research Wed, 30 May 2012 13:12:53 EST news257602340 (HealthDay) -- Babies born just a few weeks early appear to face a greater risk of developing asthma when compared with children born at full term, new research reveals. http://medicalxpress.com/news/2012-03-late-preemie-birth-linked-higher.html Inflammatory disorders Mon, 05 Mar 2012 14:20:01 EST news250174097 How we move is an excellent indicator of overall health. When we feel good, we move around continually. When we're in pain, we reduce our physical activity. This observation might seem trivial, but it has led to an original approach for evaluating chronic pain. A team from EPFL's Laboratory of Movement Analysis and Measurement (LMAM) has developed a clever, easy-to-use visual tool to help doctors assess their patients' pain levels. The research appears online February 23 in the journal PLoS One. http://medicalxpress.com/news/2012-02-chronic-pain-barcode-tool-doctors.html Health Thu, 23 Feb 2012 17:00:01 EST news249227970 If a patient is not likeable, will he or she be taken less seriously when exhibiting or complaining about pain? Reporting in the October 2011 issue of Pain, researchers have found that observers of patients estimate lower pain intensity and are perceptually less sympathetic to the patients' pain when the patients are not liked. http://medicalxpress.com/news/2011-10-discount-pain-people-dont.html Psychology & Psychiatry Mon, 03 Oct 2011 11:23:58 EST news236859827 A broad panel of leaders representing health care, academic medicine, and physician education today called for sweeping reforms in the content and format of U.S. graduate medical education (GME) to ensure that physicians are trained more effectively and efficiently to meet public needs. http://medicalxpress.com/news/2011-09-macy-foundation-medical-reforms.html Other Thu, 08 Sep 2011 12:47:29 EST news234704826 Examining brain damage that occurs when fetuses in the womb are deprived of oxygen, researchers at The Scripps Research Institute have discovered that damage does not occur randomly but is linked to the specific action of a naturally occurring fatty molecule called LPA, acting through a receptor that transfers information into young brain cells. http://medicalxpress.com/news/2011-09-discovery-block-fetal-brain-oxygen.html Medical research Thu, 01 Sep 2011 14:42:09 EST news234106838 Overall, roughly half of U.S. children taken to hospital emergency departments (EDs) for a head injury receive a head CT scan, often to ease worried parents' concerns. Yet true traumatic brain injury is uncommon. A multi-center study of more than 40,000 children with minor blunt head trauma, led by Children's Hospital Boston and UC Davis, shows that allowing a period of observation can reduce the use of head CT by as much as half without compromising care – and without exposing children to ionizing radiation. Results appear in the June 2011 issue of Pediatrics (published online May 9). http://medicalxpress.com/news/2011-05-large-ct-scans-frequently-unnecessary.html Cancer Mon, 09 May 2011 03:53:11 EST news224131941
