Autoimmune antibodies strongly linked to the severity of illness in COVID-19 patients

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 […]

FDA approves drug-free stroke rehabilitation system to treat upper extremity motor deficits

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 […]

Defective process in the development of RBCs may trigger lupus

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 […]

Availability heuristic plays a role in how physicians make complex testing decisions

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 […]

Blood clots in people with severe COVID-19 may be related to abnormal antibody response

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 […]

New stroke rehabilitation pattern based on brain-computer interface and robot technology

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, […]

Discovery of blood biomarker opens new perspectives for dietary prevention of AMD-related risks

Age-related macular degeneration (AMD) is the principal cause of vision loss in industrialized countries, with nearly 20 million people affected in Europe in 2020. Although identified as a risk factor, until now it was impossible to evaluate retinal omega-3 fatty acid deficits. A research team involving scientists from INRAE, INSERM, Université Jean-Monnet Saint-Etienne, Université de Bordeaux, ITERG and Dijon-Bourgogne and […]

A history of blood clots is not usually any reason to avoid the AstraZeneca vaccine

As hematologists, we look after many patients who have had blood clots in the past or take blood thinners. They often ask: “should I have the AstraZeneca vaccine?” The answer is usually a definitive “yes.” The blood clots we’ve seen following the AstraZeneca vaccine are completely different to other types of blood clots, such as deep vein thrombosis or a […]
