What Is the Antibody Response and Role in Conferring Natural Immunity After SARS-CoV-2 Infection? Rapid, Living Practice Points From the American College of Physicians (Version 1). | LitMetric
Description: The widespread availability of SARS-CoV-2 antibody tests raises important questions for clinicians, patients, and public health professionals related to the appropriate use and interpretation of these tests. The Scientific Medical Policy Committee (SMPC) of the American College of Physicians developed these rapid, living practice points to summarize the current and best available evidence on the antibody response to SARS-CoV-2 infection, antibody durability after initial infection with SARS-CoV-2, and antibody protection against reinfection with SARS-CoV-2.
Methods: The SMPC developed these rapid, living practice points based on a rapid and living systematic evidence review done by the Portland VA Research Foundation and funded by the Agency for Healthcare Research and Quality. Ongoing literature surveillance is planned through December 2021. When new studies are identified and a full update of the evidence review is published, the SMPC will assess the new evidence and any effect on the practice points.
Various commercial and industrial products widely use highly toxic eight-carbon-chain perfluorooctanesulfonate (PFOS), posing a significant threat to the health of living organisms. In this study, the electrochemical detection of PFOS was achieved by developing a carbon paste electrode (CPE) using MoTiAlC MAX phase. MoTiAlC was synthesized and directly used to construct the CPE.
Purpose: Assistive device non-use among individuals with disabilities is often attributed to issues in service provision and user satisfaction with assistive devices. However, systematic research on the service quality and satisfaction of assistive devices among disabled populations is lacking. Therefore, this study aims to analyze the service delivery and satisfaction of assistive devices among individuals with disabilities.
Accurate identification of decreasing trends is a prerequisite for successful conservation, but can be challenging when immigration compensates local declines in abundance. Here, we show that a potential declining trend driven by low vital rates was overridden and converted into a spectacular increase by massive immigration into the population of a semi-social raptor, the black kite Milvus migrans, breeding in a highly contaminated area near a major landfill. Immigration was promoted by a growing food-base of live prey, coupled with the attraction exerted by the progressive gathering of a large flock of non-breeders at the area, resulting in an "attraction spiral" that lured large numbers of breeders to settle into a contaminated population incapable of self-sustenance.
A thorough and precise comprehension understanding of the HIV epidemic is crucial for effective HIV prevention and control. This study aimed to update the estimates of the overall HIV burden in China in 2018 and to assess the trends of HIV prevalence, incidence, and mortality from 1985 to 2018. The Estimation and Projection Package (EPP)/Spectrum software was utilized for estimation, a method highly recommended by UNAIDS.
The current detection methods for glycoRNAs include metabolic labeling of living cells or animals and rPAL that directly detects native glycoRNAs by periodate oxidation and aldehyde ligation. Both of them have some limitations. Here we reported a simple and rapid detection of native glycoRNAs by using lectins.
