Microbiome Analysis for Wastewater Surveillance during COVID-19.

Wastewater surveillance (WS), when coupled with advanced molecular techniques, offers near real-time monitoring of community-wide transmission of SARS-CoV-2 and allows assessing and mitigating COVID-19 outbreaks, by evaluating the total microbial assemblage in a community. Composite wastewater samples (24 h) were collected weekly from a manhole between December 2020 and November 2021 in Maryland, USA. RT-qPCR results showed concentrations of SARS-CoV-2 RNA recovered from wastewater samples reflected incidence of COVID-19 cases.

Thriving, Not Just Surviving: Recognizing Burnout and Simple Tips to Start Feeling Better.

Burnout has been prevalent since before COVID-19 and continues to affect a large portion of the health-care workforce. At JADPRO Live Virtual 2021, Margaret Leddy, PA-C, MMSc, defined burnout in the setting of the oncology/hematology advanced practice role, described symptoms you can recognize in yourself and others, and provided three tips to combat burnout.

Distributions of waterborne pathogens in raw wastewater based on a 14-month, multi-site monitoring campaign.

The California State Water Resources Control Board is the first regulatory body in the United States to develop statewide regulations for direct potable reuse (DPR). To support this effort, a pathogen monitoring campaign was undertaken to develop and implement an optimized standard operating protocol to better characterize the concentration of human pathogens in raw wastewater. Methods to detect relevant viral and protozoan pathogens in raw wastewater were optimized and implemented during a 14-month monitoring campaign.

How much time is enough? Sentinel lymph node mapping time depends on the radiotracer agent.

Background: In 2014, technetium-99m tilmanocept (TcTM) replaced technetium-99m sulfur colloid (TcSC) as the standard lymphoscintigraphy (LS) mapping agent in melanoma patients undergoing sentinel lymph node biopsy (SLNB). The aim of this study was to examine differences in mapping time, intra-operative identification of sentinel lymph node (SLN), and false negative rate (FNR) between patients who underwent SLNB with TcTM compared to TcSC.

Methods: Patients who underwent SLNB between 2010 and 2018 were retrospectively identified.

Metagenomic Sequencing and Quantitative Real-Time PCR for Fecal Pollution Assessment in an Urban Watershed.

Microbial contamination of recreation waters is a major concern globally, with pollutants originating from many sources, including human and other animal wastes often introduced during storm events. Fecal contamination is traditionally monitored by employing culture methods targeting fecal indicator bacteria (FIB), namely . and enterococci, which provides only limited information of a few microbial taxa and no information on their sources.
