Hypoxia News and Research

RSS

Hypoxia is a condition in which there is a decrease in the oxygen supply to a tissue. In cancer treatment, the level of hypoxia in a tumor may help predict the response of the tumor to the treatment.

SARS-CoV-2 can adversely affect cardiac cells and heart function

A research group from Germany demonstrated a direct toxic effect of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on cardiac cells in their paper published on the bioRxiv* preprint server. The finding warrants an in-depth analysis of cardiac tissue in certain coronavirus disease (COVID-19) patients, as well as close monitoring for any direct cardiomyocyte injury.

Sleep apnea may increase the risk of severe COVID-19, say researchers

An analysis conducted by researchers at the University of Turku and Turku University Hospital in Finland has suggested that obstructive sleep apnea (OSA) may be a risk factor for severe coronavirus disease 2019 (COVID-2019).

Placentas of pregnant women with COVID-19 showed abnormalities

A study conducted by researchers at Northwestern University, Chicago, has found that the placentas of pregnant women who were infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) showed abnormalities, compared with those of uninfected women.

HMGB1 protein may play a key role in pulmonary inflammation, tissue damage in severe COVID-19 cases

In severe cases of COVID-19, a massive release of the endogenous protein HMGB1 in the lungs may contribute to pulmonary inflammation and tissue damage, according to a review article published today in the scientific journal Molecular Medicine.

Early Heparin therapy improves hypoxia in COVID-19 patients

The systemic use of heparin for treating severe coronavirus disease (COVID-19) showed significant improvements in oxygen exchange and overall clinical presentation of patients, as reported by a study from Brazil available on a preprint server medRxiv.

Preliminary findings on obesity and COVID-19 severity

In a Nature Reviews Endocrinology "Comment" authors from the German Center for Diabetes Research, the Boston Children's Hospital and the Harvard T.H. Chan School of Public Health call for more research about the relationships of obesity, disproportionate fat distribution and impaired metabolic health with the severity of COVID-19.

COVID-19 lung injury is not like high altitude pulmonary edema

A group of researchers with experience in treating high altitude pulmonary edema have written to correct the misconception in medical social media forums and elsewhere that the lung injury seen in COVID-19 is not like typical acute respiratory distress syndrome and is instead like HAPE.

Real-time imaging reveals how infiltrating glioma cells alter brain function, blood flow

The first sign of trouble for a patient with a growing brain tumor is often a seizure. Such seizures have long been considered a side effect of the tumor.

Smokers have more ACE2 receptors making it easier for SARS-CoV-2 to infect

A new study published in the European Respiratory Journal in April 2020 reveals that people with smoking-damaged lungs and those with chronic obstructive pulmonary disease (COPD) are likely to have a higher level of the angiotensin-converting enzyme II (ACE2).

Spanish study shows infections in children occur early in COVID-19 epidemics

With the spread of COVID-19, scientists are finding out more about the disease. One major aspect that is being studied is how the virus affects children. A new report from Spain, published in the journal JAMA Pediatrics in April 2020, shows that pediatric populations are infected early in the epidemic and that about 10% of those with symptoms suggestive of infection test positive. Severe infection can also occur among children, requiring hospitalization and intensive care.

New microfluidic chip can mimic hypoxic conditions after a heart attack

Researchers led by biomedical engineers at Tufts University invented a microfluidic chip containing cardiac cells that is capable of mimicking hypoxic conditions following a heart attack - specifically when an artery is blocked in the heart and then unblocked after treatment.

Finding new treatments for muscular dystrophy with CRISPR-Cas9

A new study out of Boston's Children's Hospital has used the gene-editing tool CRISPR-Cas9 to explore the fatal genetic condition called facioscapulohumeral dystrophy (FSHD, one of the family of muscular dystrophies), and to test out the potential utility of various genes involved in this disorder. The research is published in the journal Science Translational Medicine.
