A new study led by researchers at the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health found that an enzyme involved in protein translation is essential for circulating immune cells, called monocytes, to mature into tissue-resident macrophages, a specialized population of immune cells that maintain organ health by clearing dead cells and debris.

Gaps in the U.S. stroke transfer system are drastically reducing survivors' chances of receiving critical treatment and increasing the likelihood that they will leave the hospital with a disability, according to a new study published in The Lancet Neurology.

Having an ischemic stroke during pregnancy or three months after pregnancy is associated with an increased risk of cardiovascular events like heart attack or second stroke, heart disease and depression later in life.

Amid a surprisingly severe flu season and a Covid-19 resurgence, those highly contagious respiratory illnesses are drawing the largest share of media coverage and public attention.

A new, fast and easy test could revolutionize blood transfusions-giving blood centers and hospitals a reliable way to monitor the quality of red blood cells after they sit for weeks in storage.

A multi-institutional study led by the University of California, Davis, finds that living in urban areas with a higher percentage of visible trees is associated with a 4% decrease in cardiovascular disease.

The long term use of proton pump inhibitors (PPIs), a class of drugs widely used to treat acid reflux and ulcers, may not be linked to any increased risk of developing gastric (stomach) cancer, finds a study of Nordic health data published by The BMJ today.

This systematic review evaluates preclinical and clinical evidence on glucagon-like peptide-1 receptor agonists as potential treatments for substance use disorders. Findings show consistent reductions in drug- and alcohol-seeking behaviors in animal models, while human evidence remains limited, heterogeneous, and preliminary.

Natural ovulation before frozen embryo transfer is as effective as hormone treatment for achieving a healthy baby by vitro fertilization (IVF), finds a clinical trial from China published by The BMJ today.

Offering non-monetary incentives such as free access to outpatient consultations to frequent blood donors is linked to an increase in donations without compromising blood safety, finds a study from China published by The BMJ today.

Gaps in the nation's stroke transfer system are drastically reducing survivors' chances of receiving critical treatment and increasing the likelihood that they will leave the hospital with a disability, a new study suggests.

There has been a lasting and disproportionate impact of the Covid-19 pandemic on diagnosis rates for conditions including depression, asthma and osteoporosis.

Severe vitamin D deficiency is associated with a higher rate of hospitalization for respiratory tract infections such as bronchitis and pneumonia, according to a new study led by the University of Surrey.

Long-term exposure to ambient air pollution was associated with a higher risk of developing motor neuron disease and poorer prognosis after diagnosis in a large nationwide Swedish study. Higher particulate matter and nitrogen dioxide exposure were also linked to faster functional decline and increased likelihood of invasive ventilation.

Australians undergoing open-heart surgery could soon benefit from safer, simpler care and get home earlier thanks to the results of a world-first clinical trial led by Monash University's Victorian Heart Institute.

This population-based study of U.S. adults aged 70 and older found that shingles vaccination was associated with slower epigenetic and transcriptomic aging, as well as lower systemic inflammation. No significant associations were observed for neurodegeneration or cardiovascular biomarkers, highlighting domain-specific molecular effects rather than broad clinical changes.
