The salivary metatranscriptome as an accurate diagnostic indicator of oral cancer.

Despite advances in cancer treatment, the 5-year mortality rate for oral cancers (OC) is 40%, mainly due to the lack of early diagnostics. To advance early diagnostics for high-risk and average-risk populations, we developed and evaluated machine-learning (ML) classifiers using metatranscriptomic data from saliva samples (n = 433) collected from oral premalignant disorders (OPMD), OC patients (n = 71) and normal controls (n = 171). Our diagnostic classifiers yielded a receiver operating characteristics (ROC) area under the curve (AUC) up to 0.

Gut Microbiome Activity Contributes to Prediction of Individual Variation in Glycemic Response in Adults.

Limiting postprandial glycemic response (PPGR) is an important intervention in reducing the risk of chronic metabolic diseases and has been shown to impart significant health benefits in people with elevated levels of blood sugar. In this study, we collected gut microbiome activity data by assessing the metatranscriptome, and we measured the glycemic responses of 550 adults who consumed more than 30,000 meals, collectively, from omnivore or vegetarian/gluten-free diets. We demonstrate that gut microbiome activity, anthropometric factors, and food macronutrients modulate individual variation in glycemic response.

[Kidney transplantation from Covid-19 positive deceased donor: what are the consequences for recipients?].

Introduction: In recent months, with the spread of COVID 19, the number of kidney transplants from deceased donors has declined significantly in most countries. One of the reasons is the possibility of infection of the recipient with SARS-CoV-2. Determining the risk of transmission of COVID 19 with a donor organ is very important for developing a kidney transplantation policy during a pandemic.

Kidney transplantation from COVID-19 deceased donor.

We present first known case of kidney transplantation from deceased donor who was retrospectively diagnosed with COVID-19. The recipient hadn't febrile and no other symptoms of acute respiratory disease during all hospital stay. No serum anti-SARS-CoV-2 IgM, IgG were detected before and during 6 weeks after surgery.

Is Kidney Transplantation From a COVID-19-Positive Deceased Donor Safe for the Recipient?

Introduction: In recent months, the number of kidney transplants from deceased donors has declined significantly. One of the reasons is the possibility of infection of the recipient with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Determining the risk of transmission of coronavirus disease 2019 (COVID-19) with a donor organ is very important for developing a kidney transplantation policy during a pandemic.
