Male health linked to testosterone exposure in womb, study finds

Male health linked to testosterone exposure in womb, study finds

Men’s susceptibility to serious health conditions may be influenced by low exposure to testosterone in the womb, new research suggests. A study has revealed how men’s testosterone levels may be determined before they are born. Understanding why some men have less of the hormone than others is important because testosterone is crucial for life-long health Continue reading

Proposal: Managing most troubling symptoms of dementia, lessen use of drugs

Proposal: Managing most troubling symptoms of dementia, lessen use of drugs

A new approach to handling agitation, aggression and other unwanted behaviors by people with dementia may help reduce the use of antipsychotics and other psychiatric drugs in this population, and make life easier for them and their caregivers, a team of experts says. Publishing their recommendations under the easy-to-remember acronym of “DICE”, the panel of specialists in senior mental health hope to spark better teamwork among those who care for dementia patients at home, in residential facilities and in hospitals and clinics Continue reading

Proteins conspire to make breast cancer cells resistant to drug treatment

Proteins conspire to make breast cancer cells resistant to drug treatment

Scientists at Sanford-Burnham Medical Research Institute (Sanford-Burnham) provide compelling and conclusive evidence that antiestrogen resistance in breast cancer cells requires the interaction between proteins called BCAR1 and BCAR3. In the study, published in the Journal of Biological Chemistry , the researchers also identified a signaling pathway that is crucial for drug resistance mediated by this protein complex Continue reading

HIV-positive women respond well to HPV vaccine, study shows

HIV-positive women respond well to a vaccine against the human papillomavirus (HPV), even when their immune system is struggling, according to newly published results of an international clinical trial. Continue reading

Antibiotics improve growth in children in developing countries

Antibiotics improve growth in children in developing countries

Antibiotics improve growth in children at risk of undernourishment in low and middle income countries, according to researchers at McGill University who have just conducted a research literature review on the subject. Their results, published in the British Medical Journal , suggest that the youngest children from the most vulnerable populations benefit most and show significant improvements toward expected growth for their age and sex, particularly for weight. Malnutrition in early childhood, reflected in poor growth, is the cause of nearly half of all mortality worldwide in children less than five years old. Continue reading

New standards proposed for gauging muscle decline in older adults

New standards proposed for gauging muscle decline in older adults

Sarcopenia — the age-related loss of muscle mass and strength — may put up to 50 percent of seniors at greater risk for disability, yet there is no consensus within the medical community for how this condition should be measured. However, a new collection of articles appearing in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences (volume 69, number 5) lays out an empirically derived set of criteria for diagnosing sarcopenia. These recommendations are a result of the Foundation for the National Institutes of Health Biomarkers Consortium Sarcopenia Project, which includes scientists and grantees from the National Institutes of Health, along with other partners in government, academia, and the private sector.

Fiber-optic microscope will help physicians detect cancer, diseases at early stages

Fiber-optic microscope will help physicians detect cancer, diseases at early stages

An engineering researcher at the University of Arkansas has developed an inexpensive, endoscopic microscope capable of producing high-resolution, sub-cellular images of tissue in real time. The fiber-optic device, which is portable, re-usable and easily packaged with conventional endoscopes, will help clinicians detect and diagnose early-stage disease, primarily cancer. Continue reading
