The death toll from Democratic Republic of Congo's year-long Ebola outbreak has climbed above 2,000, government data showed on Friday, as responders battle to overcome community mistrust and widespread security problems.
The death in neighboring Uganda of a 9-year-old girl who had tested positive for the virus after entering the country from Congo underscored the challenge medical teams face containing the disease... read more
No 'gay gene' can predict sexual orientation, says study
Sexual orientation cannot be predicted by a single "gay gene," new research indicates.
Instead, a host of genetic and environmental factors play a role, according to a study published in Science Magazine. The findings provide insight into the complex genetics underlying human sexuality. But they do not explain it, wrote the international team of researchers who analyzed genetic data gathered... read more
Filter-based kits developed for TB diagnosis, drug-resistance testing
To address the TB diagnostic challenges, a multi-institutional team has developed three cost-effective kits that improve the sensitivity of smear microscopy, enable transport of sputum samples at ambient temperature without using bio-safe containers, and extract DNA for diagnosing drug-resistant TB. The three kits are — TB Detect, TB Concentration & Transport, and TB DNA Extraction... read more
DAPA HF: Dapagliflozin Offers New HF Therapy, Even Sans Diabetes
The diabetes drug dapagliflozin provides substantial benefits among patients with chronic heart failure with reduced ejection fraction (HFrEF) — even in those without diabetes, according to the DAPA HF trial.
The sodium-glucose cotransporter 2 (SGLT2) inhibitor reduced the relative risk for the primary outcome — a composite of time to first cardiovascular (CV) death or HF hospitalization or urgent HF visit requiring... read more
Blood Test Promising for Detecting Mild Concussion
Blood levels of glial fibrillary acidic protein (GFAP) identified mild traumatic brain injury (TBI) in patients even when a CT scan did not detect it, the TRACK-TBI study showed.
In people with negative CT findings, GFAP levels distinguished patients who were MRI-positive for intracranial lesions from patients who were MRI-negative, reported Geoffrey Manley, MD, of the University of California San Francisco, and co-authors,... read more
