Researchers develop new statistical method that generates significant genetic insights

Pleiotropy analysis, which provides insight on how individual genes result in multiple characteristics, has become increasingly valuable as medicine continues to lean into mining genetics to inform disease treatments. Privacy stipulations, though, make it difficult to perform comprehensive pleiotropy analysis because individual patient data often can't be easily and regularly shared between sites.

Gut and oral microbiomes predict COVID-19 severity

One question that continues to remain unanswered during the ongoing coronavirus disease 2019 (COVID-19) pandemic has been why is there a distinctive hit-and-miss pattern when it comes to severe disease? An interesting new study that appears on the medRxiv* preprint server pinpoints one highly relevant risk factor: the state of the oral and gut microbiomes.

Potential role of chitinase 3-like-1 in severity of COVID-19

Now, an intriguing preprint research paper on the bioRxiv server reports the identification of an enzyme called chitinase 3-like-1 (CHI3L1) that mediates this age-dependent impact of the virus and could serve as a powerful therapeutic approach in mitigating the severity of COVID-19 in this high-risk group.

Mediterranean diet has the potential to effect progression of prostate cancer

In a study to examine a Mediterranean diet in relation to prostate cancer progression in men on active surveillance, researchers from The University of Texas MD Anderson Cancer Center found that men with localized prostate cancer who reported a baseline dietary pattern that more closely follows the key principles of a Mediterranean-style diet fared better over the course of their disease.

SARS-CoV-2 viral load in saliva may be linked to COVID-19 disease severity

Researchers at Yale University School of Medicine found that SARS-CoV-2 viral loads in saliva are higher for patients with associated risk factors and underlying conditions that lead to severe COVID-19 and death. Thus, saliva viral loads could be used to predict disease severity.

Illinois is first in the nation to extend health coverage to undocumented seniors

As a nurse manager for one of Chicago's busiest safety-net hospitals, Raquel Prendkowski has witnessed covid-19's devastating toll on many of the city's most vulnerable residents — including people who lack health insurance because of their immigration status. Some come in so sick they go right to intensive care. Some don't survive.

ACE2 receptor is responsible for the wide host range of SARS-CoV-2

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is thought to have a zoonotic origin, perhaps originating in a bat coronavirus with an unknown intermediate host. It is not only very infectious but has been found to infect a wide range of mammals, including dogs, cats, ferrets, hamsters, and minks, besides non-human primates. This range may be still higher, claims a recent preprint that appeared in January 2021 on the bioRxiv server.
