The World Health Organization's vaccine experts recommended Tuesday that countries consider routine vaccination against HPV in girls as young as 4, provided it helps improve lagging vaccine coverage.

According to the World Health Organization (WHO), nearly 17.9 million people die from cardiovascular diseases worldwide every year, with heart attacks and strokes accounting for more than four out of five of those deaths. Coronary heart disease, which can lead to a heart attack if untreated, develops when fatty material (cholesterol) accumulates in the blood vessels supplying the heart. High blood cholesterol is therefore a key risk factor for coronary heart disease.

A new Houston Methodist Research Institute study finds that older adults with metabolic dysfunction-associated steatotic liver disease (MASLD) who received GLP-1-based treatment experienced significantly lower risks of liver disease–related complications, hospitalization and death compared with similar patients who did not receive the treatment.

Early axial spondyloarthritis (axSpA), with a duration of no more than two years of axial symptoms, is associated with lower long-term spinal structural damage, according to a study published online Sept. 18 in Arthritis & Rheumatology.

Some people are born with a defect in their genetic material that prevents their immune system from functioning properly. In people with a condition known as GATA2 deficiency, the body does not produce enough immune cells, leaving them at increased risk of infections and disease. Now, researchers at Aarhus University have demonstrated that they can repair the genetic defect directly in patients' own blood stem cells.

For patients with rheumatoid arthritis (RA) with sustained low disease activity (LDA), structured tapering of biologic or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) is noninferior to treatment continuation for maintaining disease control over 24 weeks, according to a study published online Oct. 6 in Arthritis & Rheumatology.

The everyday moments parents spend reading books, solving puzzles and playing with their toddlers may do more than create memories. New research shows these simple interactions engage young brains in ways that screen time cannot.

If you struggle with insomnia, could medical marijuana help you get a better night's sleep?

Acute interstitial nephritis (AIN) is a condition characterized by inflammation that damages the kidney's tubules and surrounding tissue. Often resulting from an immune reaction to common medications—including antibiotics, anti-inflammatory medications and drugs that treat acid reflux—the condition accounts for roughly 15% to 20% of biopsied cases of acute kidney injury (AKI), defined as a sudden decline in kidney function.

A large global study provides new evidence supporting the use of blood biomarkers in an Alzheimer's clinical trial to screen for elevated brain amyloid levels among potential participants who are cognitively unimpaired. The findings, published in JAMA Neurology, show that the relationship between blood biomarker levels and brain amyloid was largely similar across racial groups.
