A new approach to peripheral nerve injury? Natural killer cells in the immune system could present a target

In animal models of a totally crushed peripheral nerve, the damaged axons are broken down, allowing healthy ones to regrow. But humans rarely suffer complete axonal damage. Instead, axons tend to be partially damaged, causing neuropathic pain—a difficult-to-treat, chronic pain associated with nerve trauma, chemotherapy and diabetes. A new study in Cell, led by Michael Costigan, Ph.D., at Boston Children’s […]

Pregnancy-related stroke more common among black women

The risk of pregnancy-related stroke is much higher among black women than among white women, according to preliminary research to be presented in Honolulu at the American Stroke Association’s International Stroke Conference 2019, a world premier meeting for researchers and clinicians dedicated to the science and treatment of cerebrovascular disease. Stroke is the fifth-leading cause of death and a major […]

Blood conservation safe, effective during heart surgery

(HealthDay)—Blood conservation via intraoperative autologous donation (IAD) is safe and effective in reducing transfusions during cardiac surgery, according to research presented at the annual meeting of The Society of Thoracic Surgeons, held from Jan. 27 to 29 in San Diego. Eric Zimmerman, M.D., from the Oregon Health & Science University in Portland, and colleagues retrospectively reviewed a cardiac surgery database […]

Intensive BP treatment does not reduce dementia risk

(HealthDay)—Treating systolic blood pressure (BP) to a goal of less than 120 mm Hg rather than 140 mm Hg does not result in a significant reduction in the risk for probable dementia, according to a study published online Jan. 28 in the Journal of the American Medical Association. Jeff D. Williamson, M.D., M.H.S., from the Wake Forest School of Medicine […]

Newborn babies have inbuilt ability to pick out words, finds study

A research study of newborn babies has revealed that humans are born with the innate skills needed to pick out words from language. The international team of researchers discovered two mechanisms in 3-day-old infants, which give them the skills to pick out words in a stream of sounds. The discovery provides a key insight into a first step to learning […]

New therapeutic targets for kidney fibrosis emerge

Chronic kidney disease is a global health concern, affecting about 10 percent of the world’s population—and increasing in prevalence. A final, common pathway in chronic kidney disease is fibrosis. Just as fibrosis—or the formation of fibrous connective tissue—can cause devastating effects in the lung, liver, heart and elsewhere, fibrosis of the kidneys can ultimately lead to end-stage kidney failure. In […]

Muscle memory discovery ends ‘use it or lose it’ dogma

The old adage “use it or lose it” tells us: if you stop using your muscles, they’ll shrink. Until recently, scientists thought this meant that nuclei—the cell control centers that build and maintain muscle fibers—are also lost to sloth. But according to a review published in Frontiers in Physiology, modern lab techniques now allow us to see that nuclei gained […]

BP >120/80 mm hg linked to lower gray matter volume

(HealthDay)—In young adults, lower gray matter volume (GMV) is seen in individuals with blood pressure (BP) >120/80 mm Hg, according to a study published online Jan. 23 in Neurology. H. Lina Schaare, from the International Max Planck Research School in Leipzig, Germany, and colleagues examined the correlation between BP and GMV from structural 3T T1-weighted magnetic resonance imaging of 423 […]

Regulatory policy changes needed to bring AI into clinical decision making, study says

A new white paper from the Duke-Margolis Center for Health Policy outlines the policy needs for incorporating artificial intelligence (AI) into diagnosis and other types of clinical decision support software with effective innovation, regulation and patient protections. “AI is now poised to disrupt health care, with the potential to improve patient outcomes, reduce costs, and enhance work-life balance for healthcare […]
