The world’s first HIV-positive-to-HIV-positive lung transplant was performed at NYU Langone Health. The surgery brings new hope for HIV-positive patients in need of lung transplants, as it opens a pool of potential donors who were previously ineligible.

New antibiotic candidates for drug-resistant bacteria may reside inside prions, mis-folded protein in the brain best known for rare and fatal degenerative brain diseases. Prion and prion-like proteins may hide short peptides, named “prionins,” that can kill bacteria, suggesting proteins best known for their role in neurodegeneration may contain molecular features linked to immune defense, according to new research from the Perelman School of Medicine at the University of Pennsylvania.  

The study used AI to compare health records from 10,000 veterans and found that those who had served in roles with higher risk of blast exposure were more likely to have raised concerns related to anger to their doctor.

Chewing sugar-containing gum enhances the cardiovascular benefits of nitrate-rich vegetables.

Bending forwards, and to a lesser extent, walking a lot at work in early pregnancy, may raise the risk of miscarriage, finds a large study of more than 470,000 Danish women, published online in the journal Occupational & Environmental Medicine.

Early childhood adversity is connected to poorer physical and mental health across a person’s lifespan, and the biological mechanisms that translate the lived effects of poverty and trauma into physical functions are starting to come to light. A growing body of research has shown that psychosocial stress influences mitochondrial function, and mitochondria play a pivotal role in stress-related diseases and aging. UCLA psychologists have now connected early childhood adversity to changes in how mitochondria produce energy, which may affect cellular function with adverse effects on mental and physical health.
