Cardiovascular deaths unrelated to COVID-19 increased during the pandemic, study finds

Wed, 01/13/2021 - 10:51
As the number of COVID-19 infections continues to rise nationwide, more than 360,000 Americans have already died from the potentially deadly viral infection.

Study: Testing policies should vary based on demand to catch the most COVID-19 cases

Wed, 01/13/2021 - 10:34
With months to go in the mass rollout of COVID-19 vaccines, testing is still critical to control the surging pandemic.

Antibody-Fc-mediated innate immunity shapes COVID-19 severity

Wed, 01/13/2021 - 10:18
A short paper that appeared recently on the preprint bioRxiv server pointed to a link between specific characteristics of anti-SARS-CoV-2 antibodies associated with the severity of COVID-19.

Intranasal vaccination effectively reduces viral shedding of SARS-CoV-2 in monkeys

Wed, 01/13/2021 - 09:58
A new preprint that appeared on the bioRxiv server reports that intranasal vaccination with the D614G variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in rhesus monkeys reduces viral shedding. This is an experiment in non-human primates (NHP), and its extrapolation to humans is unclear as yet.

Structure of SARS-CoV-2 cytoplasmic tail uncovered

Wed, 01/13/2021 - 09:43
The virus's cytosolic tail also interacts with the host cell to promote its entry into the endoplasmic reticulum (ER). A new study appearing on the bioRxiv preprint server elucidates the conformation of this region of the virus, which will help understand how its form is related to its function in viral entry.

Effect of mutations in the South African SARS-CoV-2 variant on transmission and neutralization

Wed, 01/13/2021 - 09:26
One such strain is the South African 501.V2 and UK B1.1.7 strains, which have been isolated from many countries and seem to spread faster than the ancestral strain. A preprint that recently appeared on the bioRxiv server reports the computational structure of this strain and the possible effect of the mutations on infectivity and neutralization.

Bleeding disorder linked to poor clinical outcomes in COVID-19 patients

Wed, 01/13/2021 - 08:17
The novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is the pathogen responsible for the ongoing coronavirus disease 2019 (COVID-19) pandemic. Approximately 20-55% of hospitalized COVID-19 patients are reported to have deranged hemostatic laboratory parameters, which suggests coagulopathy.

Researchers discover a new approach to inhibit intrahepatic cholangiocarcinoma

Wed, 01/13/2021 - 07:49
Reprogramming the rich connective tissue microenvironment of a liver cancer known as intrahepatic cholangiocarcinoma (ICC) inhibits its progression and resistance to standard chemotherapy in animal models, researchers from Massachusetts General Hospital have found.

Mothers with multiple children report worse sleep patterns

Wed, 01/13/2021 - 07:45
Mothers with multiple children report more fragmented sleep than mothers of a single child, but the number of children in a family doesn't seem to affect the quality of sleep for fathers, according to a study from McGill University.

Antigenic "supersite" could improve design of COVID-19 vaccines

Wed, 01/13/2021 - 07:44
Researchers in the United States have defined an antigenic “supersite” within the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that could have important implications for the design of vaccines to protect against coronavirus disease 2019 (COVID-19).

Study reveals rising risk of mental health problems among COVID-19 health care professionals

Wed, 01/13/2021 - 07:41
The daily toll of COVID-19, as measured by new cases and the growing number of deaths, overlooks a shadowy set of casualties: the rising risk of mental health problems among health care professionals working on the frontlines of the pandemic.

Study investigates the metabolites involved in the growth and spread of melanoma

Wed, 01/13/2021 - 07:34
The first step in treating cancer is understanding how it starts, grows and spreads throughout the body. A relatively new cancer research approach is the study of metabolites, the products of different steps in cancer cell metabolism, and how those substances interact.

Stimulation method helps some people with spinal cord injury to regain hand and arm mobility

Wed, 01/13/2021 - 07:29
Almost 18,000 Americans experience traumatic spinal cord injuries every year. Many of these people are unable to use their hands and arms and can't do everyday tasks such as eating, grooming or drinking water without help.

Hypoxia signaling pathway could lead to COVID-19 treatments

Wed, 01/13/2021 - 07:26
Researchers in Spain have demonstrated that studying the hypoxia signaling pathway could provide opportunities for treating coronavirus disease 2019 (COVID-19).

Researchers call for stronger regulations to reduce health burden of smokeless tobacco

Wed, 01/13/2021 - 07:08
Researchers at the University of York are calling for more stringent regulatory measures to reduce the health burden of smokeless tobacco, a product often found in UK stores without the proper health warnings and as a result of illicit trading.

K-State medical director contributes to research on SARS-CoV-2 transmission and quarantine periods

Wed, 01/13/2021 - 07:02
Kyle Goerl, the medical director of Kansas State University's Lafene Health Center, is part of a collaborative team that is providing research-based guidance during the COVID-19 pandemic.

Incidence of osteoporotic hip fractures expected to escalate in some Eurasian countries

Wed, 01/13/2021 - 06:48
A detailed analysis of the burden of osteoporosis in eight Eurasian countries has found that osteoporosis is a significant and growing health problem in the region that will escalate in the future due to expected demographic changes.

Study examines the role of gut microbes in anorexia

Wed, 01/13/2021 - 06:28
You are likely familiar with the serious consequences of anorexia for those who experience it, but you might not be aware that the disorder may not be purely psychological.

Metabolites may be predictive indicators of patients at risk for recurrent major depression

Wed, 01/13/2021 - 06:14
Researchers at University of California San Diego School of Medicine, in collaboration with Dutch scientists, have found that certain metabolites -; small molecules produced by the process of metabolism -; may be predictive indicators for persons at risk for recurrent major depressive disorder.

Study: Sugar substitute doesn't lead to the development of diabetes in healthy adults

Wed, 01/13/2021 - 06:08
For those trying to live a healthy lifestyle, the choice between sugar and artificial sweeteners such as saccharin can be confusing.
