RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

NIH study identifies promising oral antiviral treatment for COVID-19

The experimental drug TEMPOL may be a promising oral antiviral treatment for COVID-19, suggests a study of cell cultures by researchers at the National Institutes of Health.

Hydroxychloroquine + Azithromycin therapy at a higher dose improved survival by nearly 200% in ventilated COVID patients

However, a fascinating new study posted to the medRxiv* preprint server suggests that such disappointment may have been both premature and unwarranted, based on a re-analysis of over 250 patients on invasive mechanical ventilation (IMV) during the first two months of the pandemic.

Newly identified protein could become a target for future cancer treatments

Researchers at the Francis Crick Institute have identified a protein that helps tumours evade the immune system and, in certain types of cancers, is linked to a poorer chance of survival. The protein could become a target for future cancer treatments.

Women who experience acute aortic dissection are more likely to die than men, shows study

Women who experience acute aortic dissection - a spontaneous and catastrophic tear in one of the body's main arteries - not only are older and have more advanced disease than men when they seek medical care, but they also are more likely to die, according to research published online today in The Annals of Thoracic Surgery.

Optic nerve activity may trigger the formation of vision-harming tumors in children

In a study of mice, researchers showed how the act of seeing light may trigger the formation of vision-harming tumors in young children who are born with neurofibromatosis type 1 (NF1) cancer predisposition syndrome.

New algorithm could be an important step toward adaptive deep brain stimulation

By delivering small electrical pulses directly to the brain, deep brain stimulation (DBS) can ease tremors associated with Parkinson's disease or help relieve chronic pain.

Study reveals potential mechanism for how traumatic brain injury leads to neurodegenerative diseases

Scientists have revealed a potential mechanism for how traumatic brain injury leads to neurodegenerative diseases, according to a study in fruit flies, and rat and human brain tissue, published today in eLife.

Small chip inserted under the skin may help predict the likelihood of recurrent stroke

For patients who have experienced certain common types of stroke, a small chip inserted under the skin may help physicians predict their likelihood of experiencing a second stroke, and therefore their likelihood of benefiting from preventive therapy.

Glycosylated hemoglobin can provide a useful estimate of atherosclerosis and cardiovascular events

The routine use of the glycosylated hemoglobin test to track blood sugar levels in the general population can identify individuals with more advanced atherosclerotic disease.

Implantable device more effective at detecting atrial fibrillation than standard of care

A clinical trial examining the efficacy of two devices to monitor and detect atrial fibrillation (AF), or an irregular heartbeat, in ischemic stroke patients--one an implantable device that monitors over 12 months, the other an external device that monitors over a 30-day period--found the implantable device is more than three times more effective in detecting AF, and both are a significant improvement over the current standard of care in Alberta, Canada.

New data reveals higher incidence of severe stroke in COVID-positive people

Among people who have strokes and COVID-19, there is a higher incidence of severe stroke as well as stroke in younger people, according to new data from a multinational study group on COVID-19 and stroke, led by a team of Geisinger researchers.

Researchers develop proof-of-concept treatment for blood disorders

Researchers at Children's Hospital of Philadelphia (CHOP) have developed a proof-of-concept treatment for blood disorders like sickle cell disease and beta-thalassemia that could raise hemoglobin levels by activating production of both fetal and adult hemoglobin.

Researchers discover a new and unique form of ALS

In a study of 11 medical-mystery patients, an international team of researchers led by scientists at the National Institutes of Health and the Uniformed Services University discovered a new and unique form of amyotrophic lateral sclerosis (ALS).

Inflammatory brain injury higher in men with acute COVID-19, finds study

The COVID-19 pandemic has been associated with both short- and long-term neurologic complications, including stroke, brain fog and persistent tiredness. A new study concludes that the effects of SARS-CoV-2 on the central nervous system (CNS) are due to the endothelial injury and inflammation that this produces in the brain.

Novel protein interactions with ACE2 disrupted by SARS-CoV-2, contributes to COVID-19 pathologies

A severe and often fatal immune response called a “cytokine storm” can occur following SARS-CoV-2 infection. Some patients suffer from a range of complications several months after testing negative for SARS-CoV-2, and this is called ‘Long Haul’ or ‘Long’ COVID-19. The causes behind this phenomenon are not well understood.

UC Riverside expert receives NIH grant to pursue research on moderate concussive brain injury

Viji Santhakumar, an associate professor of molecular, cell and systems biology at the University of California, Riverside, has received funding from the National Institute of Neurological Disaster and Stroke of the National Institutes of Health to further pursue research on moderate concussive brain injury, which results from car accidents or sports-related concussions.

Adults with obsessive compulsive disorder face higher risk of ischemic stroke

Adults who have obsessive-compulsive disorder (OCD) were more than three times as likely to have an ischemic stroke later in life compared to adults who do not have OCD, according to new research published today in Stroke, a journal of the American Stroke Association, a division of the American Heart Association.
