Patients with mitral and tricuspid valve regurgitation, a condition sometimes called "leaky heart valves," appeared to do better after two years if they had a tricuspid valve repair at the time of mitral valve surgery, according to a study supported by the National Heart, Lung, and Blood Institute (NHLBI), a…
Researchers explain why decaying SARS-CoV-2 antibodies in blood are not a problem after vaccination
One way messenger RNA (mRNA) vaccines provide robust protection against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is by creating memory B cells that can detect the spike protein. Previous work has shown that the COVID-19 vaccine induces a robust germinal center response. When there is antigenic stimulation, naive…

Simple blood test enables early detection of immunotherapy-triggered encephalitis
Immunotherapy is very effective for many cancers, but the treatment can also cause autoimmune side effects. Encephalitis is one of the most serious and difficult-to-diagnose side effects of immunotherapy. Now care staff can use a simple blood test to detect treatment-triggered encephalitis at an early stage. This finding is reported…
What makes blood vessels leaky: New insights for sepsis therapeutics
Sepsis occurs when the body works so hard to fight an infection that the over-activated immune system harms a patient’s own tissues as collateral damage. As a result, blood vessels can become leaky and major organs can’t get the oxygen and nutrients they require to sustain life. Sepsis is a…
Blood pressure rises by stealth in poorer nations
More than half a billion people worldwide live with undetected, untreated hypertension, even as the disease burden shifts from rich nations to poor countries with limited resources to detect and manage the condition. In what researchers describe as a “massive public health failure,” nearly half of the 1.28 billion people…
New method visualizes blood flow in the brain down to one blood cell
Researchers from the Skolkovo Institute of Science and Technology and Saratov State University have come up with an inexpensive method for visualizing blood flow in the brain. The new technique is so precise it discerns the motions of individual red blood cells—all without the use of toxic dyeing agents or…

Novel system may enable noninvasive and more precise measurement of cerebral blood flow
In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, cerebral blood flow is considered a vital and sensitive marker of cerebrovascular function. Optical methods offer a noninvasive approach for…
Top blood pressure monitors, as chosen by a heart doctor!
Top blood pressure monitors, as chosen by a heart doctor! Leading cardiologist gives his pick of five of the best DIY checking devices Up to one in three Britons has high blood pressure, which raises the risk of heart attacks and strokes. Normal blood pressure is less than 130 (systolic…
Post-COVID-19 neurological sequalae are not due to brain injury, study shows
In a recent study from University of Gothenburg, it has been shown that all participants achieve normalization of CNS injury biomarkers, regardless of previous disease severity or persistent neurological symptoms. Indicating that post-COVID-19 neurological sequalae are not due to active brain injury. Central nervous system involvement and signs of brain…
