A new onset of a rapid or irregular heartbeat that develops after surgery, often within a few days, is associated with an increased risk for hospitalization for heart failure among patients undergoing both cardiac and noncardiac surgery, according to a new study by Weill Cornell Medicine and NewYork-Presbyterian investigators.

A group of immune cells that normally protect against inflammation in the gastrointestinal tract may have the opposite effect in multiple sclerosis (MS) and other brain inflammation-related conditions, according to a new study by Weill Cornell Medicine and NewYork-Presbyterian researchers.

Dr. Michael Kaplitt, a professor of neurological surgery at Weill Cornell Medicine and a longtime leader in developing cutting-edge surgical therapies for movement disorders, leads a team that has been awarded a three-year, $8.9 million grant from the Aligning Science Across Parkinson’s (ASAP) initiative. 

Stroke patients received clot-busting medication more quickly,and had better recoveries, when treated by an ambulance-basedmobile stroke unit (MSU) compared with standard emergency room (EMS) care.

Children with infantile spasms, a rare form of epileptic seizures, should be treated with one of three recommended therapies and the use of non-standard therapies should be strongly discouraged, according to a study of their effectiveness by a Weill Cornell Medicine and NewYork-Presbyterian investigator and collaborating colleagues in the Pediatric Epilepsy Research Consortium.

The degree to which the brain’s wiring aligns with its patterns of activity can vary with sex and age, and may be genetic, suggests a study published by Weill Cornell Medicine investigators.
