Metabolic and immune markers as tools for risk stratification and monitoring in COVID-19

In a new study posted to the medRxiv* server scientists from Weil Cornell University and Stony Brook University in New York attempted to identify the metabolic and immune markers associated with severe COVID-19 disease using high-throughput targeted nuclear magnetic resonance (NMR) spectroscopy and high-dimensional flow cytometry. This will facilitate risk stratification, monitoring, and therapeutic interventions in COVID-19 patients.

‘No-touch’ technique to remove leg veins leads to better outcomes after heart bypass surgery

When a modified surgical technique was used to gently remove sections of leg veins used in coronary artery bypass surgery, the grafts were less likely to become blocked and fewer people had a recurrence of heart-related chest pain, according to new research published today in the American Heart Association's flagship journal Circulation.

Allergic reactions provide protection against yeast-triggered asthma, research shows

We think of asthma and other allergic diseases as unnecessary aberrant immune responses that do more harm than good. However, new evidence by an international team led by researchers at Baylor College of Medicine shows that some allergic reactions provide necessary protection against highly invasive and potentially lethal infectious agents, such as yeast.

Research reveals a new role for platelets in COVID-19 blood vessel damage

Abnormal crosstalk between blood platelets and cells lining blood vessels is one cause of deadly organ damage in patients with severe COVID-19, a new study finds.

Natural killer cells mediate a trade-off between wound healing and bacterial defense

Natural killer cells do not just kill cancer cells or cells infected with viruses, they also mediate a trade-off between wound healing and bacterial defense in skin wounds.

Sepsis mortality risk linked to the degree of platelet reduction

Researchers have revealed that the degree of platelet reduction, rather than absolute platelet count, is linked to mortality risk in sepsis.

Research reveals the impact of nicotine-containing e-cigarettes on the body

Using e-cigarettes containing nicotine causes an immediate increase in the formation of blood clots and a deterioration in the ability of small blood vessels to expand and dilate, as well as raised heart rate and blood pressure, according to research presented at the European Respiratory Society International Congress.

Hypopituitarism and COVID-19 – exploring a possible bidirectional relationship?

In a recent study published in Reviews in Endocrine and Metabolic Disorders, the researchers discuss the extra-pulmonary manifestations of COVID-19.

Home blood collection device could be used for measuring antibodies against SARS-CoV-2

A device that could make it possible for patients to draw their own blood at home was successfully used to collect blood samples for measuring antibodies against SARS-CoV-2, the virus that causes COVID-19, researchers at the University of Washington School of Medicine in Seattle report.

COVID-19 associated mucormycosis cases in India

India continues to grapple with the coronavirus disease (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). To date, the country has reported over one million new cases for the past 28 days.

Research offers insights to restore blood vessel integrity during sepsis, other conditions

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.

Researchers develop new drug-free treatment to accelerate healing of chronic diabetic wounds

About one-fourth of people with diabetes develop painful foot ulcers, which are slow to heal due to low oxygen in the wound from impaired blood vessels and increased inflammation. These wounds can become chronic, leading to poor quality of life and potential amputation.

Study may pave way for new treatment strategies to limit the progression of solid tumors

Researchers at the University of British Columbia's faculty of medicine and BC Cancer Research Institute have uncovered a weakness in a key enzyme that solid tumour cancer cells rely on to adapt and survive when oxygen levels are low.

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).

Pregnant women with COVID-19 are more susceptible to pre-eclampsia

A review of the scientific literature published by Brazilian researchers shows that pregnant women infected by the novel coronavirus run a higher risk of developing pre-eclampsia, a pregnancy complication characterized by persistent high blood pressure, usually in the second half of pregnancy or shortly after delivery.

Brain organoids provide a valuable model to study autism

Variations in the 16p11.2 region of the genome are associated with autism spectrum disorder. While people with genetic deletions in this region have larger heads (macrocephaly) and people with genetic duplications have smaller heads (microcephaly), both variation types affect brain development and function.

Stiffening of heart’s blood vessels associated with lack of enzyme that fosters cell ‘chatter’

In a study in mice, Johns Hopkins Medicine researchers have found that the smooth muscle cells lining the walls of blood vessels can lose their elasticity and lead to vascular stiffening, a condition that can precede heart disease and stroke.

Brain refreshing takes place during the dream-active phase of sleep

Scientists have long wondered why almost all animals sleep, despite the disadvantages to survival of being unconscious.
