The neurological effects of COVID-19

What is the relationship between COVID-19 and the brain? A new review published in Tropical Biomedicine summarizes the key findings on how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes severe COVID-19 infection, disrupts brain activity and produces a range of long-term neurological disorders.

TTUHSC investigator evaluates the potential of neurolysin as a therapeutic target for stroke

Ischemic stroke, the second leading cause of death worldwide, occurs when a vessel to the brain is blocked, reducing blood flow to the brain and depriving it of critical supplies of oxygen and nutrients.

Large study of COVID vaccine side effects in Sweden

Recently, researchers from Sweden reported population-based, age- and sex-specific background incidence rates of conditions that represent potential COVID-19 vaccine adverse events of special interest (AESI) in the general Swedish population with the help of registered data. This study is published on the medRxiv* preprint server.

Thrombolytic therapy may be safe for people with ischemic stroke and unruptured aneurysms

Clot-busting drugs are the main treatment for stroke, but they have often not been recommended for people who have an aneurysm in their brains that has not ruptured. An aneurysm is a bulge in the wall of a blood vessel in the brain.

Restoring visual function after stroke with gene therapy

Most strokes happen when an artery in the brain becomes blocked. Blood flow to the neural tissue stops, and those tissues typically die. Because of the locations of the major arteries in the brain, many strokes affect motor function.

Naturally occurring protein associated with better stroke recovery in mice

A naturally occurring protein that blocks an inflammatory immune response was associated with better stroke recovery in a study conducted in mice, according to preliminary research to be presented at the American Heart Association's Vascular Discovery: From Genes to Medicine Scientific Sessions 2021.

Blood clot risks are high following SARS-CoV-2 infection, not vaccination

Researchers from the University of Oxford have today announced the results of a study into thrombocytopenia (a condition with low platelet counts) and thromboembolic events (blood clots) following vaccination for Covid-19, some of the same events which have led to restricted use of the Oxford-AstraZeneca vaccine in a number of countries.

Study reveals better outcomes for patients treated on a mobile stroke unit

Ischemic stroke patients treated on a mobile stroke unit received anti-clot medication faster and ended up with less disability at 90 days, according to a study published today in the New England Journal of Medicine led by researchers at The University of Texas Health Science Center at Houston and Memorial Hermann-Texas Medical Center.

COVID-19 presents a higher risk of blood clots than vaccination

The current study found that people were at a slightly higher than normal risk of blood clots after receiving Oxford-AstraZeneca and Pfizer vaccines.

Study: Epilepsy brain implant does not induce changes to patients' personalities or self-perceptions

A next-generation brain implant currently in clinical use for treating refractory epilepsy – to help prevent symptoms including seizures – does not induce changes to patients' personalities or self-perceptions, a new study of patient experiences shows.

Family of proteins could be effective in reducing damage from ischemic stroke

Boosting a family of naturally occurring proteins that dampens inflammation in the body has been shown to be effective in reducing damage from an ischemic stroke, according to preclinical researchers at The University of Texas Health Science Center at Houston.

Assessing the risks of thrombotic events post vaccination with ChAdOx1 and BNT162b2 vaccines in England

Researchers aim to better understand the population-level thrombotic risks post COVID-19 vaccination with both the ChAdOx1-S and BNT162b2 vaccines.

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).

New regional policy to guide EMS response could improve stroke care

Patients with a suspected acute ischemic stroke who are taken by emergency medical services (EMS) directly to comprehensive stroke centers rather than the nearest stroke center for care are more likely to receive endovascular therapy, according to research led by investigators at the University of Chicago Medicine, in collaboration with local healthcare and emergency response groups.

Mobile interventional stroke team travels to patients for providing faster access to surgical treatment

Stroke patients were almost twice as likely to be functionally independent-;mobile and able to perform daily tasks-;at 90 days post-stroke if they were treated by a specialized mobile stroke team that traveled to them to perform mechanical clot removal, compared to those who were transferred to a thrombectomy stroke center, according to research conducted within the Mount Sinai Health System and published today in Stroke, a journal of the American Stroke Association, a division of the American Heart Association.

Women who suffer emergent large vessel occlusion strokes less likely to receive timely care

Women are less likely than men to receive timely care for strokes caused by blockages in large vessels, known as emergent large vessel occlusion (ELVO), according to researchers with The University of Texas Health Science Center at Houston.

Static magnetic field from MRI scanner decreases blood-brain barrier opening volume

MRI-guided focused ultrasound combined with microbubbles can open the blood-brain barrier (BBB) and allow therapeutic drugs to reach the diseased brain location under the guidance of MRI.

Albumin supplementation improves human fertility, fights infection

A new University of California, Irvine-led study reveals albumin (Alb), among the most abundant proteins in the body, activates a proton channel (hHv1), also widespread in the body, giving sperm the ability to penetrate and fertilize an egg, and allowing white blood cells to secrete large amounts of inflammatory mediators to fight infection.

New research identifies a link between the gut microbiome and strokes

A recent study demonstrates the impact of diets that are high in choline and trimethylamine on increasing stroke severity and functional deficits.

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.
