Life expectancy gap closes dramatically between those with HIV and general population

An observational cohort study finds that mortality among persons entering HIV care decreased dramatically between 1999 and 2017, with the largest decrease seen between 2011 and 2017. Those entering HIV care remained at modestly higher risk for death in the years after starting care than comparable persons in the general U.S. population. The findings are […]

Nanomaterials shape and form influences their ability to cross the blood brain barrier

Nanomaterials found in consumer and health-care products can pass from the bloodstream to the brain side of a blood-brain barrier model with varying ease depending on their shape—creating potential neurological impacts that could be both positive and negative, a new study reveals. Scientists found that metal-based nanomaterials such as silver and zinc oxide can cross […]

The same neural pathways promote maternal and paternal behaviors in voles

Like female voles, connections between oxytocin neurons in the hypothalamus and dopamine neurons in reward areas drive parental behaviors in male voles, according to new research published in JNeurosci. Motherhood receives most of the attention in the research world, yet in 5% of mammals—including humans—fathers provide care, too. The “love hormone” oxytocin plays a role […]

Detecting oesophageal cancer with AI

Experts at UCL and spinout company Odin Vision working with clinicians at UCLH have used artificial intelligence (AI) to help detect early signs of oesophageal cancer. The first procedure in the world using the AI technology was performed at University College Hospital by UCLH consultant gastroenterologist Dr. Rehan Haidry. The system, called CADU, uses AI […]

Defibrillators in GP clinics should be standard

People who suffer a cardiac arrest while in a GP clinic are twice as likely to survive if they are promptly defibrillated with an automated external defibrillator rather than waiting to be defibrillated after paramedics arrive, according to the authors of research published today by the Medical Journal of Australia. More than 25,000 out-of-hospital cardiac […]
