Pressure difference and vortex flow of blood in heart chambers may signal heart dysfunction

Japanese scientists at Tokyo University of Agriculture and Technology (TUAT), Teikyo University of Science, and Juntendo University have found—in animal studies—a close relationship between vortex flow and pressure differences in the ventricles, or lower chambers, of the heart. The new information could inform the development of new markers for cardiovascular dysfunction that can lead to

Hospitals may divert ambulances to avoid treating certain patients

Some hospitals may strategically divert ambulances to avoid treating low‐paying patients who are uninsured or who have Medicaid, according to a recent analysis. Charleen Hsuan, assistant professor of health policy and administration at Penn State, led a study that examined whether hospitals are more likely to temporarily close their emergency departments to ambulances—a process known

Research reveals how the Internet may be changing the brain

An international team of researchers from Western Sydney University, Harvard University, Kings College, Oxford University and University of Manchester have found the Internet can produce both acute and sustained alterations in specific areas of cognition, which may reflect changes in the brain, affecting our attentional capacities, memory processes, and social interactions. In a first of

How chronic inflammation may drive down dopamine and motivation

Growing evidence shows that the brain’s dopamine system, which drives motivation, is directly affected by chronic, low-grade inflammation. A new paper proposes that this connection between dopamine, effort and the inflammatory response is an adaptive mechanism to help the body conserve energy. Trends in Cognitive Sciences published the theoretical framework developed by scientists at Emory

Arsenic in drinking water may change heart structure

Drinking water that is contaminated with arsenic may lead to thickening of the heart’s main pumping chamber in young adults, a structural change that increases the risk for future heart problems, according to new research in Circulation: Cardiovascular Imaging, an American Heart Association journal. “People drinking water from private wells, which are not regulated, need

Have sleep apnea? Using your CPAP device consistently may slow memory loss

Mild cognitive impairment (MCI) refers to having problems with your memory and decision-making abilities. Usually, people with MCI experience few if any problems with performing their daily activities. Experts say that MCI could be a stage between normal aging and Alzheimer’s disease. A growing number of studies suggest that obstructive sleep apnea (OSA), or “sleep-disordered

Mobilizing the lymphatic system may help combat obesity-induced metabolic syndrome

The search by scientists to find ways to combat obesity continues. Recently, investigators have been exploring whether they can engage the lymphatic system to help regulate obesity-induced inflammation of fat (adipose) tissue and restore systemic metabolic fitness. In a study appearing in he American Journal of Pathology, researchers report that augmenting lymphatic vessel formation in

Wearable sensor may cut costs and improve access to biofeedback for people with incomplete paraplegia

A new electromyography biofeedback device that is wearable and connects to novel smartphone games may offer people with incomplete paraplegia a more affordable, self-controllable therapy to enhance their recovery, according to a new study presented this week at the Association of Academic Physiatrists Annual Meeting in Puerto Rico. Electromyography (recording electrical activity of muscles) biofeedback
