A phase I study of a next-generation CAR T cell therapy showed a 52 percent complete remission rate for patients with relapsed/refractory lymphoma. The findings, led by researchers in the Perelman School of Medicine at the University of Pennsylvania, were published today in the New England Journal of Medicine. 

People who eat more ultra processed foods like cold breakfast cereal, cookies and hot dogs are more likely to have early signs of Parkinson’s disease when compared to those who eat very few ultra processed foods, according to a study published in the May 7, 2025, online in Neurology^®, the medical journal of the American Academy of Neurology. The study does not prove that eating more ultra processed foods causes early signs of Parkinson’s disease; it only shows an association.

Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain’s small blood vessels, according to a study published May 7, 2025, online in Neurology^®, the medical journal of the American Academy of Neurology. The study found the brain changes were strongly associated with the severity of drops in oxygen levels during rapid eye movement (REM) sleep. The study does not prove that sleep apnea causes this degeneration; it only shows an association.

National Jewish Health researchers with the Advanced Diagnostic Laboratories have developed a groundbreaking molecular diagnostic test capable of accurately diagnosing a major genetic cause of chronic obstructive pulmonary disease (COPD) known as Alpha-1 Antitrypsin Deficiency (AATD). The novel 23-SNP alpha-1 antitrypsin (AAT) assay, as described in a recent study published in CHEST Pulmonary, significantly improves the speed and precision of AATD diagnosis by identifying multiple genetic mutations associated with the disease. The test addresses a long-standing challenge in the medical community.

Healthy hearts are adaptable, and heartbeats exhibit complex variation as they adjust to tiny changes in the body and environment. Mass General Brigham researchers have applied a new way to measure the complexity of pulse rates, using data collected through wearable pulse oximetry devices. The new method, published in Journal of the American Heart Association, provides a more detailed peek into heart health than traditional measures, uncovering a link between reduced complexity and future cognitive decline.

In a groundbreaking study led by a multinational team of experts, researchers at National Jewish Health and their collaborators in Colorado, Illinois, Taiwan and Israel have introduced a new term to the medical lexicon: silicosarcoidosis. This novel designation describes cases where patients’ lung tissue exhibits overlapping features of both silicosis and sarcoidosis, two serious pulmonary diseases linked to occupational exposure to respirable crystalline silica (RCS) commonly found in construction, mining, and engineered stone fabrication.
