Clergy can fight HIV on faith-friendly terms

In the United States, where blacks bear a disproportionate burden of the HIV/AIDS epidemic, black religious institutions could help turn the tide. In a new study in PLoS ONE based on dozens of interviews and focus groups with 38 of Philadelphia’s most influential black clergy, physicians and public health researchers find that traditional barriers to preaching about HIV prevention could give way to faith-friendly messages about getting tested and staying on treatment.

PROVIDENCE, R.I. [Brown University] — The public health community has long struggled with how best to reduce HIV infection rates among black Americans, which is seven times that of whites. In a new paper in the journal PLoS ONE, a team of physicians and public health researchers report that African-American clergy say they are ready to join the fight against the disease by focusing on HIV testing, treatment, and social justice, a strategy that is compatible with religious teaching.

Testosterone-fuelled Infantile Males Might be a Product of Mom’s Behaviour

By comparing the testosterone levels of five-month old pairs of twins, both identical and non-identical, University of Montreal researchers were able to establish that testosterone levels in infancy are not inherited genetically but rather determined by environmental factors. “Testosterone is a key hormone for the development of male reproductive organs, and it is also associated with behavioural traits, such as sexual behaviour and aggression,” said lead author Dr. Richard E. Tremblay of the university’s Research Unit on Children’s Psychosocial Maladjustment. “Our study is the largest to be undertaken with newborns, and our results contrast with the findings gained by scientists working with adolescents and adults, indicating that testosterone levels are inherited.” The findings were presented in an article published in Psychoneuroendocrinology on May 7, 2012.

COLUMBUS, Ohio – Women who are obese before they become pregnant are at higher risk of having children with lower cognitive function – as measured by math and reading tests taken between ages 5 to 7 years – than are mothers with a healthy prepregnancy weight, new research suggests. (more…)

People with Paralysis Control Robotic Arms using Brain-Computer Interface

A new study in Nature reports that two people with tetraplegia were able to reach for and grasp objects in three-dimensional space using robotic arms that they controlled directly with brain activity. They used the BrainGate neural interface system, an investigational device currently being studied under an Investigational Device Exemption. One participant used the system to serve herself coffee for the first time since becoming paralyzed nearly 15 years ago.

PROVIDENCE, R.I. [Brown University] — On April 12, 2011, nearly 15 years after she became paralyzed and unable to speak, a woman controlled a robotic arm by thinking about moving her arm and hand to lift a bottle of coffee to her mouth and take a drink. That achievement is one of the advances in brain-computer interfaces, restorative neurotechnology, and assistive robot technology described in the May 17 edition of the journal Nature by the BrainGate2 collaboration of researchers at the Department of Veterans Affairs, Brown University, Massachusetts General Hospital, Harvard Medical School, and the German Aerospace Center (DLR).

Feeding Tubes May Worsen Pressure Ulcer Risk

In the Archives of Internal Medicine, researchers report that despite the conventional wisdom that feeding tubes help dementia patients resist pressure ulcers, feeding tubes actually are associated with an increased risk of ulcers developing. The tubes also don’t promote healing.

PROVIDENCE, R.I. [Brown University] — A new study led by Brown University researchers reports that percutaneous endoscopic gastric (PEG) feeding tubes, long assumed to help bedridden dementia patients stave off or overcome pressure ulcers, may instead make the horrible sores more likely to develop or not improve.
