Estrogen modestly protective against COVID-19?

Almost from the beginning, scientists have been struck by the disproportionately higher numbers of men and older adults who have developed severe COVID-19 disease compared to younger individuals and women. Prior research has shown that in 37 of the 38 countries from which sex-stratified data was available, males were at a higher risk of death. Also, post-menopausal women are at increased risk of severe COVID-19. However, the biological underpinnings of this have been less visible.

How COVID-19 lockdown affected the heart

A new study published on the preprint server medRxiv in August 2020 shows that heart rate variability assessments, used to evaluate the health of the heart and blood vessels, are useful in identifying changes in health and well being throughout lockdown related to COVID-19.

Study reveals impact of TP53 gene mutations on MDS severity

Considered the "guardian of the genome," TP53 is the most commonly mutated gene in cancer. TP53's normal function is to detect DNA damage and prevent cells from passing this damage on to daughter cells.

FDA approves CBD oral solution for treatment of seizures related to tuberous sclerosis complex

Today, the U.S. Food and Drug Administration approved Epidiolex (cannabidiol) [CBD] oral solution for the treatment of seizures associated with tuberous sclerosis complex (TSC) in patients one year of age and older.

War of sugars - estrogen provides protection in COVID-19

Now a new study published on the preprint server bioRxiv in July 2020 reports that sex hormones could affect the function of the fusion protein that is dependent upon the human ACE2 receptor, thus preventing the entry of the virus into the host cell.

Researchers report a liquid biopsy for COVID-19

A new study published on the preprint server medRxiv in July 2020 reports the potential of cell-free DNA as a marker of the severity of disease in COVID-19. This could help triage patients as well as provide a prognostic marker.

Study shows how chronic psychological stress leads to sickle cell crises

A new study shows how chronic psychological stress leads to painful vessel-clogging episodes--the most common complication of sickle-cell disease (SCD) and a frequent cause of hospitalizations.

Study finds fungal isolates with high levels of virulence in different hospitals

A group of researchers from Brazil, Denmark, Italy and Spain analyzed 884 samples of fungi of the genus Candida collected from 16 hospitals and found a significant number of clusters in more than one hospital.

Study explains the mechanisms used by human brain to recognize specific smells

However, this precision only concerns the first "door" for the odors' recognition, namely the nose. But something changes when the information collected and processed by the nose arrives in a more central structure of the brain, called the olfactory cortex.

New study shows the mechanism of brain to recognize specific smells

An Italian-American research conducted by researchers at the IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology) in Rovereto (Italy) and Harvard University in Boston (Usa) explains for the first time the mechanisms used by our brain to recognize specific smells.

Study shows chemical exposure may disrupt sleep in menopausal women

For menopausal women who have difficulty sleeping, it might be because of chemicals in the environment.A new study based on data from the Midlife Women's Health Study suggests that exposure to various chemicals, such as phthalates, found in hundreds of products used daily, is associated with sleep disruptions in midlife women

Mental health problems peak alongside COVID-19 in Australia

A new study has found that during the peak of the outbreak in Australia, the rates of psychological distress, anxiety, and depression symptoms rose among adults. The study is published in the latest issue of the journal PLOS ONE.

Study reveals molecular cause underlying rare genetic disorder

Virginia Tech scientists have revealed how a nonfunctioning version of an ordinary gene impairs brain structure and function. The findings help explain a genetic form of microcephaly -- a condition where babies' heads are small and grow more slowly than their peers.

Clinical trials of hydroxychloroquine in COVID-19 outpatients reported as safe

According to new research, the use of hydroxychloroquine among outpatients in clinical trials, without high-risk factors for cardiac arrhythmia, is safe.

Face masks do not lead to false sense of security, shows study

Existing limited evidence suggests that wearing face coverings to protect against COVID-19 does not lead to a false sense of security and is unlikely to increase the risk of infection through wearers foregoing other behaviours such as good hand hygiene, say researchers from the University of Cambridge and King's College London.

Non-invasive urine test being offered free to the NHS to help clear bladder cancer diagnoses backlog

A HIGHLY accurate urine test which can rule out bladder cancer with a negative-predictive value of 99% using a hospital laboratory’s standard ELISA testing equipment is today being offered free to the NHS to help urologists clear the backlog of people waiting for a diagnosis and monitoring as a result of COVID-19 hospital closures.
