Corneas from diabetic donors perform well in vision restoring surgeries

Many eye banks won't accept corneas from donors with diabetes, concerned they might be harder to prepare for transplant surgery or are more likely to fail.

New research helps explain how the brain implements visual working memory

Imagine you are a security guard in one of those casino heist movies where your ability to recognize an emerging crime will depend on whether you notice a subtle change on one of the many security monitors arrayed on your desk.

Botulinum toxin injections could be a powerful tool for treating post-amputation pain

Botulinum toxin injections provided greater short-term relief for phantom limb pain than standard medical and surgical care among Ukrainian war amputees, reports a new study led by Northwestern Medicine and Ukrainian physicians.

Study clarifies the complex interaction between gut bacteria and common gastrointestinal disorder

Research from the University of Gothenburg, Sweden, clarifies the complex interaction between gut bacteria and IBS.

Earlier menopause and reduced cardiac function may negatively affect brain health

Women face a higher risk of developing both cardiovascular disease and Alzheimer's disease than men. Cardiovascular disease is linked to an increased likelihood of Alzheimer's disease, especially among women.

New study offers hope for patients with treatment-resistant focal epilepsy

About one-third of patients with focal epilepsy, a common form of the neurological disorder, are believed to respond poorly to available therapies.

Tailored deep brain stimulation offers new hope for hard-to-treat epilepsy

Doctors and researchers at the University of Pittsburgh and UPMC have developed a new treatment for epilepsy patients who don't respond to medication and aren't candidates for surgery. Their approach, published today in Nature Communications, uses deep brain stimulation (DBS) that is tailored to each patient's unique brain wiring.

Blood proteins reveal MS immune system attack starts years before symptoms

By the time patients start seeking care for multiple sclerosis (MS), the disease has already been damaging their brains for years. But until recently, scientists didn't understand which brain cells were being targeted or when the injury began.

AGA updates guidelines for Barrett's Esophagus to catch cancer early

The American Gastroenterological Association (AGA) released a new clinical practice guideline on the surveillance of Barrett's esophagus, the only known precursor to esophageal cancer (adenocarcinoma), a highly lethal cancer whose incidence has risen substantially over recent decades.

Researchers discover how a brain circuit allows eating despite anxiety

How do mammals manage to eat in situations that cause anxiety, step into exposed spaces, or slow down when anxiety drives them to keep moving? A new study pinpoints a leptin-sensitive circuit in the lateral hypothalamus that helps to overcome anxiety to perform essential behaviors such as exploring, feeding, and limiting maladaptive hyperactivity.

Economic growth drives disparities in global cancer research

New research reveals that the number and complexity of cancer clinical trials since 2001 have varied across low- and middle-income countries (LMICs), with economic growth contributing to disparities, but only to a certain extent. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.

Molecular evidence connects higher childhood cognitive function to longer lifespan

Researchers led by Dr. W. David Hill at the University of Edinburgh have identified a significant genetic correlation between childhood cognitive function and longevity, providing the first molecular genetic evidence that intelligence measured in youth shares genetic factors with lifespan.

Study suggests earlier start of hormone therapy optimizes long-term health outcomes

Menopause may take a toll on women physically and emotionally due to declining estrogen levels. For some, the use of hormone therapy has proven valuable in managing bothersome menopause symptoms.

Genetic and inflammatory factors amplify the link between earlier menopause and cognitive risk

Women are significantly more likely than men to develop Alzheimer's disease. Earlier age at menopause is associated with a greater risk for late-life cognitive decline and Alzheimer's disease.

Researchers link postmenopausal status to increased dry eye risk

Many symptoms, such as hot flashes and vaginal dryness, are commonly associated with the menopause transition. One of the lesser-known symptoms that worsens in midlife is dry eyes. A new study suggests that postmenopausal women exhibit a higher prevalence of dry eye disease than perimenopausal women.

Transdermal hormone therapy offers potential reduction in anxiety and depression

Hormone therapy–oral and transdermal–remains the most effective treatment for such bothersome menopause symptoms as hot flashes and is generally considered safe for most patients. A new study shows that risk profiles are different based on how the hormones are administered.

Study reveals differing prescribing patterns for menopause therapy

Not all healthcare professionals receive the same type of formal education. That may help explain the results of a new study which suggests that provider type and specialty greatly affect whether a woman receives prescription medication treatment for menopause-related care and, if so, what kind of treatment she receives.
