Multiple pain locations contribute to greater knee pain

A new study found that patients with osteoarthritis (OA) of the knee who also have pain in other joints were more likely to experience greater knee pain. Specifically, pain in the lower back as well as foot pain and elbow pain on the same side as the affected knee were associated with more severe knee pain. Full details appear in the December issue of Arthritis Care & Research, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology.

COPD Biomarkers Qualification Consortium launched

The COPD Foundation announces the launch of an unprecedented collaborative effort to pool information on Chronic Obstructive Pulmonary Disease (COPD): the COPD Biomarkers Qualification Consortium (CBQC). The CBQC brings together government agencies, academic institutions and pharmaceutical companies that will share research data on COPD biomarkers—indicators of disease progression/severity.

Researchers reveal mechanism of early-stage anthrax infection

Researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have determined a key mechanism by which Bacillus anthracis bacteria initiate anthrax infection despite being greatly outnumbered by immune system scavenger cells. The finding, made by studying genetically modified mice, adds new detail to the picture of early-stage anthrax infection and supports efforts to develop vaccines and drugs that would block this part of the cycle.

PTSD doubles veteran's risk of death

Post-traumatic stress disorder (PTSD) more than doubles a veteran's risk of death from any cause and is an independent risk factor for cardiovascular disease, according to research presented at the American Heart Association's Scientific Sessions 2010.

Vitamin C can prevent and reverse sepsis

Physicians caring for patients with sepsis may soon have a new safe and cost-effective treatment for this life-threatening illness. Research led by Dr. Karel Tyml and his colleagues at The University of Western Ontario and Lawson Health Research Institute have found that vitamin C can not only prevent the onset of sepsis, but can reverse the disease.

Obesity linked to heightened sense of smell for food

New research shows that obese and overweight people have a greater sense of smell for food. The study at the University of Portsmouth explains why some people struggle to stay slim. The researchers say that it is known that part of the brain that processes information about odour is also connected to the feeding centres of the brain. This study adds to the knowledge and is published in the journal Chemical Senses.

Studies explore lifestyle's influence on wellness and brain health

New research is providing a deeper understanding of how individual actions - such as exercising, sensory stimulation, or drinking - influence brain health and outcomes. This new knowledge could ultimately lead to interventions in age-related cognitive declines, drug abuse, stroke, and brain injury, separate from or in combination with traditional pharmacological approaches. These findings were presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.

New slice-tilting instrument for in-vitro research on brain tissue

The nanoelectronics research centre imec and Peira, a Belgium-based manufacturer of pharmaceutical and chemical research instruments, jointly developed an innovative slice-tilting instrument for in-vitro research on brain tissue. The new tool enables long-term studying of brain cultures through electronic stimulation and read-out, essential in getting insight into the functioning of the brain.

Study finds gender differences linked to gaming and health risks associated with problematic gaming

A new study on gaming and health in adolescents, conducted by researchers at Yale School of Medicine, found some significant gender differences linked to gaming as well as important health risks associated with problematic gaming. Published today in the journal Pediatrics, the study is among the first and largest to examine possible health links to gaming and problematic gaming in a community sample of adolescents.

Teen brain responds differently to drugs than adult

New research released today shows teenagers respond differently to drugs than adults and explores the long-lasting effects of drug use on brain development. One study shows people who start using drugs at a young age have greater cognitive shortfalls, including mental flexibility. Animal studies also suggest adolescents are more susceptible to lower doses of cocaine, are willing to work more for a cocaine "fix" than adults, and are at risk of developing compromised stress responses.
