Even though previous studies have been shown the link between regular exercises and improved health the exact dose-response relation remains unclear. Guenther Samitz, researcher in physical activity and public health at the Centre for Sports Sciences and University Sports of the University of Vienna has investigated this relationship with a meta-study representing more than 1.3 million participants. The research project was carried out in collaboration with public health scientists and epidemiologists of the Universities of Bern, Switzerland and Bristol, UK. The results of the study have been published in International Journal of Epidemiology. http://medicalxpress.com/news/2011-10-early-mortality-percent-physical-sports.html Health Thu, 20 Oct 2011 13:13:59 EST news238335229 There are many reasons why people with chronic kidney disease (CKD) often lose fitness and have increasing difficulty performing normal daily tasks, but new research shows scientific evidence for the benefits of regular exercise for people with CKD, including those with a kidney transplant. They can improve their physical fitness, walk further, have healthier blood pressures, healthier heart rates, higher health-related quality of life scores and better nutritional characteristics compared to those who don't exercise. So concludes a systematic review published in The Cochrane Library. http://medicalxpress.com/news/2011-10-regular-health-people-long-term-kidney.html Health Wed, 05 Oct 2011 03:41:58 EST news237004910 A higher dose of radiation (74 Gy) does not improve overall survival for non-small cell lung cancer that has spread to the lymph nodes, compared to the standard radiation dose (60 Gy), according to an interim analysis of a late-breaking randomized study presented at the plenary session, October 3, 2011, at the 53rdAnnual Meeting of the American Society for Radiation Oncology (ASTRO). http://medicalxpress.com/news/2011-10-higher-dose-lung-cancer-patients.html Cancer Mon, 03 Oct 2011 12:36:17 EST news236864165 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 (Medical Xpress) -- Researchers interested in stress at work have been concerned at the increased intensity of work in the EU over the past 20 years. A more detailed breakdown has shown that this increase between 1995 and 2005 occurred in all countries with only one exception, the UK.

A multidisciplinary Bochum-based research group, led by Prof. Dr. Martin Tegenthoff (Bergmannsheil Neurology Department) and Prof. Dr. Christoph Maier (Bergmannsheil Department of Pain Therapy), has now demonstrated for the first time that with unilateral CRPS excitability increases not only in the brain area processing the sense of touch of the affected hand. In addition, the brain region representing the healthy hand is simultaneously "disinhibited". The group has been performing research on and treatment of CRPS for a number of years. The researchers are reporting the new findings in the renowned journal Neurology. http://medicalxpress.com/news/2011-09-disinhibited-brain.html Neuroscience Wed, 21 Sep 2011 11:27:18 EST news235823200 Although society's perception might be that surgeons endure greater mental challenges and stress in their work duties than a primary care doctor, new research from experts at the University of Cincinnati (UC) shows that this isn't necessarily the case. http://medicalxpress.com/news/2011-09-physicians-varying-specialties-similar-mental.html Health Thu, 08 Sep 2011 10:50:01 EST news234697080 Lymphoma is a cancer that affects organs of the immune system, including the lymph nodes. In a subtype of the disease called extranodal lymphoma, tumors arise in non-lymphoid organs, such as the tongue and tonsils. Patients with extranodal lymphoma of the head and neck often undergo radiation therapy, but this treatment frequently damages the salivary glands and causes dry mouth, which can lead to problems with eating, speaking and swallowing. http://medicalxpress.com/news/2011-08-imrt-outcomes-patients-extranodal-lymphoma.html Cancer Mon, 15 Aug 2011 04:15:22 EST news232600508 A new study by York University researchers finds that practicing yoga reduces the physical and psychological symptoms of chronic pain in women with fibromyalgia. http://medicalxpress.com/news/2011-07-yoga-boosts-stress-busting-hormone-pain.html Psychology & Psychiatry Wed, 27 Jul 2011 13:40:03 EST news230991979 Participants in a congress were asked to wear a tag for two days in order to study their movements and interactions within a population. The data, collected by a French-Italian team including researchers from CNRS, Inserm, the Universite Claude Bernard Lyon and the CHU de Lyon, makes it possible to envisage the simulation of the spread of infection risks within a population, or even the optimization of the response to the expansion of an epidemic. The results of this work are published on 11 July in BMC Medicine. http://medicalxpress.com/news/2011-07-tags-epidemics.html Diseases, Conditions, Syndromes Fri, 22 Jul 2011 10:37:13 EST news230549818 As part of the Target Safely initiative, the American Society for Radiation Oncology (ASTRO) has developed a white paper, the first of a series of such papers, on the safe use of integrating intensity modulated radiation therapy (IMRT) into the radiation oncology clinic.
