Researchers decipher anti-MOG antibody construction, paving way for therapies

MOG Antibody-associated Disease (MOGAD) is a rare autoimmune disease of the central nervous system. The blood of patients contains antibodies against myelin oligodendrocyte glycoprotein (MOG), a protein in the myelin layer that surrounds the neurons in the brain. It is believed that these antibodies contribute to the destruction of this protective layer in the brain.

Study finds small sex differences in recovery after ischemic stroke

When examining recovery during the first year after an ischemic stroke, a new study has found for daily tasks such as eating, dressing and driving, female participants experienced slightly worse recovery than male participants.

High-dose rifampicin does not improve survival in tuberculosis meningitis

Each year, 11 million people worldwide develop tuberculosis, and about 1.4 million die from it. Meningitis occurs in 1–2% of patients and is the most severe complication of tuberculosis, arising when the bacteria reach the brain.

ECG-based AI model doubles early liver disease diagnoses

As rates of obesity, high blood pressure, type 2 diabetes and sleep apnea increase, cases of advanced chronic liver disease and resulting liver scarring or cirrhosis also are rising. Patients often are diagnosed based on symptoms, such as gastrointestinal bleeding, fluid retention or jaundice, which happen when liver disease has progressed to a late stage.

Heavy menstrual bleeding linked to iron deficiency in teenage girls

More than half of teenage girls experienced heavy bleeding and 40 per cent had an iron deficiency. The research, led from Lund University in Sweden, also shows that young teenage girls who experience heavy menstrual bleeding – and are therefore at greater risk of iron deficiency – can be identified using a simple questionnaire.

Research reveals how the gut microbiome supports successful pregnancy

Gut microbes may play a key role in training a mother's immune system to adapt to the developing fetus during pregnancy, according to a preclinical study by Weill Cornell Medicine investigators.

Strong heart health lowers long-term death risk in cancer survivors

Higher Life’s Simple 7 cardiovascular health scores were associated with lower long-term all-cause and cancer mortality in cancer survivors from a large Italian cohort. Inflammation, resting heart rate, and vitamin D statistically explained a substantial share of these associations, supporting shared cardiometabolic pathways across cancer and cardiovascular disease.

New tool can predict recurrence risk in patients with pancreatic neuroendocrine tumors

Cedars-Sinai investigators, leading a multi-institutional team, have developed and validated a tool to predict which patients with pancreatic neuroendocrine tumors (PanNETs) need closer monitoring because their cancer is more likely to recur.

Study examines fairness of oxygen desaturation thresholds in sleep apnea diagnosis

Obstructive sleep apnea (OSA) is a common sleep disorder in the U.S. affecting tens of millions, with estimates ranging from 25 to more than 80 million adults.

Intermittent fasting edges daily calorie cuts for blood pressure and long-term cardiovascular risk estimates

In a real-world registry study of adults with overweight or obesity, 5:2 intermittent fasting and daily calorie restriction both improved blood pressure over 12 weeks. Intermittent fasting produced modestly greater reductions in systolic and pulse pressure and a larger drop in BMI-based 30-year cardiovascular risk scores, without superior lipid or glycaemic effects.

Plant-based omega-3s work better than expected in a year-long diet study

A year-long, diet-controlled intervention shows that flaxseed oil–derived alpha-linolenic acid significantly increases erythrocyte EPA, DPA, and DHA across omnivorous, vegetarian, and vegan diets. The magnitude of improvement is driven mainly by baseline omega-3 status, while absolute EPA and DHA levels in vegans remain lower than in omnivores.

Mucus-inspired hydrogel resists stomach acid and promotes gastrointestinal healing

The Hong Kong Polytechnic University (PolyU) has developed an acid-resistant "ultra-stable mucus-inspired hydrogel" (UMIH), marking a breakthrough in the field of gastrointestinal medicine.

Lysophosphatidylcholines show gene-dependent effects in early Alzheimer’s disease

A new study presents robust evidence on the role of lysophosphatidylcholines (LPCs) in the onset of Alzheimer's disease. Researchers discovered that LPCs-compounds that transport a variety of healthy fatty acids to the brain-either promote Alzheimer's or protect against it, depending on a person's genetics.
