Perioperative medicine emerges as a system wide strategy for better surgery outcomes19:41 Perioperative medicine is emerging as a transformative, comprehensive, system-wide approach to patient care before, during, and after surgery – that reduces complication rates and hospital days, provides better health outcomes, and improves health system performance, according to a special article in the Online First edition of Anesthesiology, the peer-reviewed medical journal of the American Society of Anesthesiologists (ASA). Brain immune cells found to regulate anxiety and grooming behaviors19:41 A study led by a University of Louisville School of Medicine pediatrics and child neurology researcher reveals how a specific signaling mechanism in microglia, the brain's immune cell, can regulate anxiety and grooming behaviors. These behaviors are core symptoms of autism and obsessive-compulsive spectrum disorders. Clinical trial challenges long held beliefs about treating brittle bone disease18:37 Increasing bone density in patients with a rare genetic condition that causes bones to break easily does not prevent fractures, a large clinical trial has found. Stanford scientists map the molecular diversity of different global populations18:05 Researchers at the Stanford School of Medicine have found that ethnicity and geography may influence human molecular makeup - from metabolism and immunity to gut microbiota and biological aging. Retinal stimulation via contact lenses effective as antidepressants in mice18:05 Materials scientists have designed brain-stimulating contact lenses that are as effective as Prozac at treating depression in mice. The soft, transparent contact lenses have in-built electrodes that deliver mild electrical signals to the brain via the retina to stimulate specific brain regions associated with depression. Study traces adult heart disease risk back to the womb18:05 A child's future heart health may be partially shaped before they are born, reports a new Northwestern Medicine study that found pregnancy complications are linked to poorer cardiovascular health in offspring more than 20 years later. Identifying the methodology gap that prevents treatment of infection-triggered chronic diseases17:01 Thousands of Americans develop chronic persistent symptoms-such as fatigue, cognitive difficulties ("brain fog"), and other debilitating issues-each year following acute infections from Lyme disease, COVID-19, and other pathogens. Efforts to identify causes and produce treatments have failed. However, 16 leading researchers think they know part of the problem: study design. Thyroid hormone profiles provide critical prognostic clues for patients facing liver failure16:29 Early and accurate prognostic assessment is crucial to prevent disease progression in liver failure. Thyroid hormones (THs), particularly triiodothyronine (T3), are key metabolic regulators and play an important role in liver regeneration. Liver failure is frequently complicated by non‑thyroidal illness syndrome (NTIS), characterized by low T3 with normal or slightly elevated TSH and T4. Scientists udentify methylphenidate as an effective tool for combating chronic cancer related fatigue15:56 A new meta-analysis in the May 2026 issue of JNCCN-Journal of the National Comprehensive Cancer Network provides updated evidence that methylphenidate-type psychostimulants-a class of medication that increases dopamine and norepinephrine availability in the brain-can provide meaningful relief for cancer-related fatigue. Study reveals how brain cells process vision amidst thousands of synaptic inputs15:56 Even in the primary visual cortex, a brain region named for its specialized role in processing basic features of what the eyes see, not every neuron ends up answering the call to process properties of visual input. Maybe that's because each neuron receives a wide variety of inputs via thousands of circuit connections, or "synapses," and has to opt to respond to the visual information vs. somethin… |
