New approach can reduce unnecessary evaluations of swollen lymph nodes after COVID-19 vaccination

Swelling of lymph nodes in the armpit area is a normal response to COVID-19 vaccinations, but when they are seen on mammograms, they can be mistaken for nodes that are swollen because of cancer. In some cases, the nodes are biopsied to confirm they are not cancer.

Is the CDC 10-day COVID-19 quarantine guideline enough?

Researchers at the University of Florida and the Florida Department of Health evaluated test positivity rates for SARS-CoV-2 infection among student contacts. The team found that nine days are not enough to ascertain that the student did not contract the virus.

SARS-CoV-2 transmission bottleneck is of the order of one to three virions

Now, a new study, posted to the bioRxiv preprint server by the same researchers, focussing on the Austrian region, found that SARS-CoV-2 transmission bottlenecks to be much tighter than previously thought.

Lab study of South African SARS-CoV-2 variant and Moderna vaccine: reduced neutralization, but still protective

Researchers from the US recently compared antibody binding and viral neutralization against 2 SARS-CoV-2 variants that emerged in different parts of the world. The researchers used sera from spike mRNA vaccinated and naturally infected individuals against a circulating B.1 variant and the emerging B.1.351 variant. The study is published on the preprint server bioRxiv.

Full characterization of mammalian-produced SARS-CoV-2 receptor binding domains

A research paper recently uploaded to the preprint server bioRxiv by Dominguez-Vega et al. (23rd Feb, 2021) describes an in-depth structural analysis of the RBD of the spike protein expressed in mammalian Chinese hamster ovary (CHO) cells and human embryonic kidney (HEK293) cells, providing a new understanding of protein structure and function.

Mapping the dominance of the SARS-CoV-2 UK variant in Europe

A research paper recently uploaded to the preprint server medRxiv* by Vespignani et al. (February 22nd, 2021) uses mathematical models to map the spread of this lineage across Europe, establishing that a 50% increase to the transmissibility of the variant would allow it to become dominant in major metropolitan areas by the end of March 2021.

Complement system appears to be specifically implicated in severe COVID-19

Researchers in the United States have conducted a study showing that activation of the complement system is specifically implicated in the pathogenesis of severe coronavirus disease 2019 (COVID-19), rather than being a broader indicator of critical illness.

Study investigates characteristics of high utilizers for psychiatric hospital services

Dropping out of high school, having schizophrenia, or being diagnosed with a co-occurring personality disorder increases the likelihood of someone becoming a "high utilizer" of inpatient psychiatric hospital services, according to a new study by researchers at The University of Texas Health Science Center at Houston .

Travelers to the tropics are more prone to acquiring superbacteria than previously thought

Exploring exposure to superbacteria, researchers at the University of Helsinki and Helsinki University Hospital got unexpected results from an international collaborative study conducted in real time among 20 travelers to Southeast Asia.

Study shows antibody responses persisting 10 months after SARS-CoV-2 infection

Researchers in Italy have conducted a study showing that patients who had tested positive for infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) still had neutralizing antibodies against the virus 10 months later.

Study takes a closer look at the impact of COVID-19 pandemic on dental hygienists

Despite having been designated as high risk for COVID-19 by the Occupational Safety and Health Administration, a new study finds 3.1 percent of dental hygienists have had COVID-19 based on data collected in October 2020.
