April 20, 2018 An experimental compound appears to improve stroke outcome by reducing the destructive inflammation that can continue months after a stroke, scientists report. Rats consuming compound 21 following a clot-based stroke – the most common type in humans – don’t have a smaller stroke size but do have better memory and movement in […]Continue Reading ...

Expectant mothers have long complained of inattention, forgetfulness and reduced cognitive functioning during pregnancy. They weren’t wrong. Credit: www.shutterstock.com So-called “baby brain” refers to increased forgetfulness, inattention, and mental “fogginess” reported by four out of five pregnant women. These changes in brain function during pregnancy have long been recognised in midwifery folklore, but our new […]Continue Reading ...
Just before 3 a.m., the distress call came in to the Coast Guard’s Small Boat Rescue Station in Seattle: A young woman and another person were on a weather-battled paddleboat in the middle of Puget Sound—and they were sinking. The Coast Guard’s Travis Curley, 31, and three other crew members raced their 45-foot response boat […]Continue Reading ...
Dermatologist Murad Alam, MD, thinks — and then he acts. As chief of cutaneous and aesthetic surgery in dermatology at Northwestern University Feinberg School of Medicine in Chicago, Alam thinks about how to improve patient outcomes, reduce intraoperative pain, and improve overall patient experience, but he also worries about the rising tide of bureaucracy that […]Continue Reading ...
Retinal blood vessels blocked by immune cells can cause vision loss. Credit: Peter Campochiaro Johns Hopkins researchers have discovered a cell signaling pathway in mice that triggers vision loss in patients with diabetic retinopathy and retinal vein occlusion – diseases characterized by the closure of blood vessels in the retina, leading to blindness. In experiments […]Continue Reading ...
Credit: CC0 Public Domain Researchers at the Duke Human Vaccine Institute have led an effort to develop a more accurate way to gauge the incidence of HIV infections in large populations, which will improve research and prevention strategies worldwide. The new method more correctly identifies new vs. long-standing infections – an important distinction for determining […]Continue Reading ...
A Binghamton University senior and her colleagues recently uncovered evidence that the current treatment for Parkinson’s disease may not be as effective as it could be. Lakshmi Hareendran was part of a research team investigating drug treatment for Parkinson’s, a neurodegenerative disorder caused by a loss of the brain chemical dopamine. The dopamine circuit involved […]Continue Reading ...
PodMed is a weekly podcast from Texas Tech. In it, Elizabeth Tracey, director of electronic media for Johns Hopkins Medicine, and Rick Lange, MD, president of the Texas Tech University Health Sciences Center in El Paso, look at the top medical stories of the week. This week’s topics include anticoagulation after knee or hip surgery, […]Continue Reading ...
SAN FRANCISCO — Three-fourths of patients with newly diagnosed advanced renal cell carcinoma (RCC) had objective responses to the combination of axitinib (Inlyta) and pembrolizumab (Keytruda), a preliminary clinical trial showed. Overall, 38 of 52 (73.1%) had tumor responses, including four complete responses. An additional eight patients had stable disease during treatment with the combination. […]Continue Reading ...
Action Points Note that this cluster-randomized trial demonstrated that an intervention focusing on having family members provide direct care to NICU patients was associated with significant increases in infant weight gain. Be aware that the intervention was quite time-intensive, requiring at least 6 hours of family presence 5 days a week. Family Integrated Care, an […]Continue Reading ...
Action Points Note that this global survey study found that, broadly speaking, cesarean section rates have risen over the past 10 years. Most countries show a wealth-related inequality, whereby wealthier individuals are more likely to have a C-section. Caesarean section rates have increased in most countries during the past decade, with substantial variations between and […]Continue Reading ...
Patients hospitalized for intracerebral hemorrhage (ICH) were more likely to die before discharge if they had prior oral anticoagulant use, a study showed. In-hospital mortality rates reached 32.6% for those who had been on warfarin (Coumadin), 26.5% for those on non-vitamin K antagonist oral anticoagulants (NOACs), and 22.5% among patients with no history of oral […]Continue Reading ...

Computers are learning to distinguish whether skin lesion images are benign or malignant and require further treatment. It appears they are on par with, if not more accurate than, many dermatologists, a study shows. Stanford University researchers compared a computer-driven deep neural network with dermatologists’ ability to visually classify possible melanoma and basal cell or […]Continue Reading ...
