Mast cell activation may underlie inflammation in severe COVID-19

A new preprint research paper posted to the medRxiv* server points to mast cells as major culprits in the etiology of severe and critical COVID-19. This could suggest suitable therapeutic and preventive interventions to reduce the morbidity and mortality of this viral illness.

Patients with obesity at greater risk of developing long-term complications of COVID-19

A Cleveland Clinic study shows that survivors of COVID-19 who have moderate or severe obesity may have a greater risk of experiencing long-term consequences of the disease, compared with patients who do not have obesity.

Study uncovers mechanisms by which microRNAs drive atherogenesis in a cell-type-specific manner

Researchers at the University of Eastern Finland have uncovered potential mechanisms by which microRNAs (miRNA) drive atherogenesis in a cell-type-specific manner.

Could semen quality indicate SARS-CoV-2 insult susceptibility in polluted areas?

In a recent review in Environmental Science and Pollution Research, Italian researchers focused on “the evidence that correlates the degree and type of pollution with the increased susceptibility of many countries to this pandemic and proposes human semen as an early marker of the environmental health and the general health of individuals.” Their observations are based on a robust body of experimental evidence.

“Cognitive clock” emerges as a new way to measure brain health

Researchers have developed a novel method to monitor the brain health of patients to improve the early diagnosis and treatment of certain diseases.

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.

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.

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.

Diabetes remission diet can provide blood pressure control, reduce the need for anti-hypertensive drugs

New research has shown that if people achieve and maintain substantial weight loss to manage their type 2 diabetes, many can also effectively control their high blood pressure and stop or cut down on their anti-hypertensive medication.

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.

Study uncovers new mechanism of Alzheimer's that disorganizes blood vessels around amyloid plaques

Researchers at the Biomedicine Institute of Seville have discovered a new mechanism of Alzheimer's disease that disorganizes the blood vessels around amyloid plaques, one of the characteristic features of the disease.

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.

Neuropathology of COVID-19 patients caused by infection of brain pericytes

Recently, researchers from the UK and Sweden used highly sensitive multiplexed immunohistochemistry to study the brain tissue of COVID-19 patients and controls to analyze ACE2 expression in brain pericytes of patients with neurological symptoms. They also used spatial immunophenotyping to assess inflammation in brain tissue of COVID-19 patients.

Researchers report key study results on duplex ultrasound for diagnosis of ICA stenosis

Online first in Vascular Medicine, researchers from the Intersocietal Accreditation Commission (IAC) Vascular Testing division report findings of their multi-centered study of duplex ultrasound for diagnosis of internal carotid artery (ICA) stenosis.

Tsimane's brains experience less brain atrophy than Westerners as they age, indicates study

A team of international researchers has found that the Tsimane indigenous people of the Bolivian Amazon experience less brain atrophy than their American and European peers.

Study finds no difference in physician-patient gender concordance

While some studies suggest female patients treated by female physicians have better outcomes, there does not appear to be a relationship between operator and patient gender and outcome in patients undergoing coronary angioplasty or stenting. T

Decreasing activity of ZMPSTE24 protease with age and comorbidities may make elderly COVID-19 patients vulnerable

Studies have shown that circulating levels of PAI-1, the coagulation cascade activator, are considerably higher in COVID-19 patients with severe respiratory illness compared to patients with bacterial-sepsis and acute respiratory distress syndrome (ARDS). Hence the increase in PAI-1 levels is recognized as an early marker of endothelial dysfunction in COVID-19 patients.

Landmark study confirms that controlled blood pressure is key to prevent stroke, heart disease

Follow-up data from the landmark SPRINT study of the effect of high blood pressure on cardiovascular disease have confirmed that aggressive blood pressure management -- lowering systolic blood pressure to less than 120 mm Hg -- dramatically reduces the risk of heart disease, stroke, and death from these diseases, as well as death from all causes, compared to lowering systolic blood pressure to less than 140 mm Hg.

Antithrombotic endothelial dysfunction is prevented by Tie2 activation in severe COVID-19

Researchers from the US recently assessed if severe COVID-19 is linked to procoagulant dysfunction of the endothelium and changes in the Tie2-angiopoietin axis. They assessed circulating endothelial markers in a study cohort of 98 patients with mild, moderate, or severe COVID-19. This study is published on the medRxiv* preprint server.
