Researchers Find Link Between Low Cognitive Score And Risk Of Brain Injury
Date: Mar-13-2013Men with low socioeconomic status at highest risk Young men with low cognitive function and low socioeconomic status are significantly more likely to suffer from mild traumatic brain injury than those without, a study published today on bmj.com suggests. It is estimated that there are 10 million cases of traumatic brain injury globally every year with mild traumatic brain injuries being responsible for 70-90% of these. Incidence is highest among young males...
Exposure To DDT Linked To High Blood Pressure In Women
Date: Mar-13-2013Babies in utero exposed to high levels of the pesticide DDT are three times more likely to develop hypertension in adulthood, a new study by the University of California Davis suggests. Previous research has proven that adults exposed to DDT are at an elevated risk for high blood pressure. However the current study, published in the journal Environmental Health Perspectives is the first of its kind to exhibit a link between prenatal exposure to DDT and hypertension in adulthood...
Breastfeeding Does Not Lower Risk Of Child Obesity
Date: Mar-13-2013Breastfeeding does not appear to lower a child's risk of being overweight or obese. The finding came from a new study led by researchers at the University of Bristol, England, and was published in JAMA. Even though no benefits regarding bodyweight were found, the authors emphasized that the breastfed children in their study had fewer episodes of gastrointestinal infection and atopic eczema during infancy, and better cognitive development by the age of 6.5 years...
Osteoporosis An Increased Risk If Your Grandfather Suffered A Hip Fracture
Date: Mar-13-2013Has your paternal or maternal grandfather broken their hip on any occasion? In that case there is a greater risk that your own bones are more fragile as an adult. This has been demonstrated in a thesis at the Sahlgrenska Academy, University of Gothenburg, Sweden based on a study of over 1,000 young adults in Gothenburg, which identified those factors increasing the risk of bone fragility in men. The thesis of the PhD student Robert Rudäng at the Sahlgrenska Academy, University of Gothenburg, has evaluated how different factors affect skeletal health during adult life...
Lifelong Exercise Significantly Improves Cognitive Functioning In Later Life
Date: Mar-13-2013Exercising regularly as a kid can result in improved cognitive functioning later in life, according to a study published in the journal Psychological Medicine. A group of researchers at King's College London found that intensive lifelong exercise can significantly improve people's brain function at the age of 50. It is already well known that exercise can work wonders for clearing the mind, improving blood circulation, and also has significant effects on memory and brain-specific mechanisms...
Preventing HIV Infection With Anti-HIV Drugs In People At Risk Is Cost-Effective
Date: Mar-12-2013An HIV prevention strategy in which people at risk of becoming exposed to HIV take antiretroviral drugs to reduce their chance of becoming infected (often referred to as pre-exposure prophylaxis or PrEP), may be a cost-effective method of preventing HIV in some settings, according to a study by international researchers published in this week's PLOS Medicine...
Use Of Adjunctive Antipsychotic Medications In Depression
Date: Mar-12-2013A study published this week in PLOS Medicine finds that while antipsychotic medications are associated with small-to-moderate improvements in depressive symptoms in adults, there is little evidence for improvement on measures of quality of life and these medications are linked to adverse events such as weight gain and sedation. The results of the study, conducted by Glen Spielmans of Metropolitan State University in St...
Ethical Oversight Needed For Social Network Health Research
Date: Mar-12-2013Participant-led research, such as studies conducted via social networks, are increasingly common and have several advantages over more standard research but there are some concerns about their ethical oversight, according to experts writing in this week's PLOS Medicine...
How To Reduce One's Risk Of Colon Cancer
Date: Mar-12-2013Colon cancer, which is usually a preventable and highly curable disease, is the second cancer killer in the USA, say gastroenterologist Dr. Felice Schnoll-Sussman, NewYork-Presbyterian/Weill Cornell Medical Center, and Dr. Benjamin Lebwohl, NewYork-Presbyterian/Columbia University Medical Center. Dr. Schnoll-Sussman, who is also acting director of The Jay Monahan Center for Gastrointestinal Health, said: "It's important for people to understand that with proper screening, colon cancer can not only be detected early, but often can be prevented from developing." Dr...
How Insect Wings Destroy Bacteria
Date: Mar-12-2013In a new study, researchers describe how the veined wing of the Clanger cicada is the first known example of a natural biomaterial that kills bacteria on contact, using only its physical structure, unaided by chemical or biological agents. Tiny nanopatterns on the locust-like insect's wing surface simply tear the microorganisms apart. By studying such physical properties researchers hope to spur the design of new antibacterial materials that can be used on handrails and similar frequently-touched surfaces...
