Treatment guidelines say patients who undergo minimally invasive aortic heart valve replacements should receive two antiplatelet drugs to reduce the risk of dangerous blood clots. A Loyola Medicine study has found that a single antiplatelet drug may work just as well, with lower risks of life-threatening bleeding and other complications.
It’s a longstanding mystery why salamanders can perfectly regenerate their tails whereas lizard tails grow back all wrong. By transplanting neural stem cells between species, Pitt researchers have discovered that the lizard’s native stem cells are the primary factor hampering tail regeneration.
Medicare patients nationwide have low rates of preventive care visits – with the lowest rates found in older adults of minority race/ethnicity, reports a study in the September issue of Medical Care. The journal is published in the Lippincott portfolio by Wolters Kluwer.
In 1993, neurologist Camilo Gomez, MD, coined a phrase that became a fundamental rule of stroke care: "Time is brain!" The longer therapy is delayed, the less chance it will succeed. But the "time is brain" rule is not as simple as it once seemed, Dr. Gomez now reports in the Journal of Stroke & Cerebrovascular Diseases.

The nuclear physics result, which has implications for the dynamics of neutron stars, has been published in the journal Nature.
Although national guidelines advise doctors to discuss the benefits and harms of lung cancer screening with high-risk patients because of a high rate of false positives and other factors, those conversations aren’t happening the way they should be, according to a study by researchers from the University of North Carolina Lineberger Comprehensive Cancer Center.
The study’s findings lay the framework for applying deep learning and computer vision techniques to radiological imaging.
Adopting an Islamic concept of coping with spiritual struggles, known as “spiritual jihad,” is associated with post-traumatic growth and virtuous behaviors—and related to reductions in anxiety and depression, according to a new Case Western Reserve University study published in the journal Religions.
Fruit flies don’t appear to use their tiny, translucent wings for optimal flight, as one might expect. The speedy appendages seem to be doing double duty, helping the insect sniff out food, mates and other important scents, according to new research from The Ohio State University.
Researchers at Duke Cancer Institute have tracked the missing T-cells in glioblastoma patients. They found them in abundance in the bone marrow, locked away and unable to function because of a process the brain stimulates in response to glioblastoma, to other tumors that metastasize in the brain and even to injury.
A new approach to find unmarked gravesites could help narrow the scope and potentially speed up the search for clues during crime scene investigations. Geospatial researchers with the Department of Energy’s Oak Ridge National Laboratory and forensic scientists at University of Tennessee used LIDAR to detect telltale signs of recently buried human remains.
Pedestrian injuries and fatalities in the U.S. have steadily increased during recent years. In 2015, 5,376 pedestrians were killed and 70,000 injured. Prior research showed an association between the number of neighborhood alcohol stores and risk of pedestrian injury. However, it is unclear whether this was because alcohol stores were located in dense retail areas with already-heavy pedestrian traffic, or whether alcohol stores pose a unique neighborhood risk. This study compared the number of pedestrian injuries that occur near alcohol stores to those that occur near similar retail stores that do not sell alcohol.
Johns Hopkins Medicine researchers say a study designed to see if reducing the amount of anesthesia reduces the risk of postoperative delirium in older patients surprisingly found that lighter sedation failed to do so in severely ill people undergoing hip fracture repair.
Adolescents with a strong hand grip — an indicator of overall muscle strength — have better odds of being healthy over time, according to a two-year study of 368 elementary school children. A simple, non-invasive measure of grip strength can help identity risks of pre-diabetes and cardiovascular disease, issues of increasing concern as obesity in youths rises.

The first full characterization measurement of an accelerator beam in six dimensions will advance the understanding and performance of current and planned accelerators around the world.
Bacteria—especially Gram-negative strains—are becoming increasingly resistant to current antibiotic drugs, and the development of new classes of antibiotics has slowed. Faced with these challenges, investigators are studying the potential of combination therapy, in which two or more drugs are used together to increase or restore the efficacy of both drugs against a resistant bacterial pathogen. Now new research indicates that such synergy may work even when bacteria become resistant to colistin, which is considered a treatment agent of last resort.
Adolescents with serious conduct and substance use problems are five times more likely to die prematurely than their peers, with roughly one in 20 dying by their 30s, according to new research.
Adolescents make up more than a quarter of the population in developing countries. Only 1.6 percent of global development assistance for health from 2003-2016 went to adolescent health. Resource allocation failed to address many of the diseases that take the worst toll on adolescent health, such as depressive disorders, anemia and injuries.
