Patients with new spinal cord injuries whose blood pressure is maintained within a newly defined range during surgery may stand a better chance of regaining some mobility and functionality – even in patients with the most devastating injuries – according to a new study by researchers at UC San Francisco. For one patient in particular, a father of two injured […]

Statement highlights: Kawasaki disease is the most common cause of acquired heart disease that develops in early childhood, creating inflammation in blood vessels, particularly heart arteries. It usually occurs before age 5 and is more common among children of Asian descent, although it affects children of all races and ethnicities. It can occur through adolescence (and rarely beyond), and the […]

The brain is arguably the most crucial aspect of our existence. Our brain health governs how well we function. In turn, our brain health is determined by the blood supply to our brain via “cerebral blood flow” (CBF), which regulates the supply of oxygen and nutrients and removes metabolic by-products. An imbalance in CBF can lead to brain disorders such […]

After infection with SARS-CoV-2, where does the immune system store the memory to provide long-term protection against reinfection? Though numerous studies have examined blood to track immune responses to SARS-CoV-2, a new study of COVID survivors shows that the memory of the infection is primarily stored in T and B cells within the lung and the lymph nodes surrounding the […]

The presence of special immune system defense molecules, called autoimmune antibodies, has been strongly tied to how poorly people fare when hospitalized with COVID-19, a new study shows. Led by researchers at NYU Grossman School of Medicine, the study detected the autoimmune antibodies in the blood of more than a third of men and women on admission to hospital and […]

The U.S. Food and Drug Administration today approved the MicroTransponder Vivistim Paired VNS System (Vivistim System), a first-of-its-kind, drug-free rehabilitation system intended to treat moderate to severe upper extremity motor deficits associated with chronic ischemic stroke—a stroke caused by a blockage of blood flow to the brain with long-lasting symptoms—using vagus nerve stimulation (VNS). People who have lost mobility in […]

The autoimmune disease lupus may be triggered by a defective process in the development of red blood cells (RBCs), according to a study led by researchers at Weill Cornell Medicine. The discovery could lead to new methods for classifying and treating patients with this disease. The researchers, who published their findings August 11 in Cell, found that in a number […]

Findings Emergency department physicians who saw patients with a pulmonary embolism-;a blood clot in the lung-;were about 15% likelier over the next 10 days to test subsequent patients for the same thing. Background Rules of thumb, also known as heuristics, could influence how physicians deliver care. One such rule of thumb is the "availability heuristic," under which a person assesses […]

Inflammation and blood clotting seen in very severe cases of COVID-19 may be caused by the antibodies sent to fight the disease activating unnecessary platelet activity in the lungs. A new paper published in the journal Blood reveals how antibodies produced by our bodies to protect against COVID-19 are triggering increased function of platelets, which may be causing fatal blood […]

Strokes, which occur when the blood supply to part of our brain is interrupted or reduced, are the leading cause of death and disability in the adult population. Among the patients who survive, 75% will experience difficulties carrying out daily activities independently and need long-term functional exercises and rehabilitation. But the outcomes using traditional rehabilitation equipment are poor. In addition, […]
