Background Artificial intelligence chatbots such as ChatGPT (OpenAI) have garnered excitement about their potential for delegating writing tasks ordinarily performed by humans. Many of these (eg, recommendation letters) social and professional ramifications, making the biases in ChatGPT’s underlying language model a serious concern. Objective Three preregistered studies used text analysis program Linguistic Inquiry Word Count to investigate gender bias letters written human-use sessions...
The effects of mutations in continuously emerging variants SARS-CoV-2 are a major concern for the performance rapid antigen tests. To evaluate impact on 17 antibodies used 11 commercially available tests with emergency use authorization, we measured antibody binding all possible Nucleocapsid point using mammalian surface-display platform and deep mutational scanning. results provide complete map antibodies' epitopes their susceptibility to escape. Our data predict no vulnerabilities...
Rapid antigen tests (RATs) have become an invaluable tool for combating the COVID-19 pandemic. However, concerns been raised regarding ability of existing RATs to effectively detect emerging SARS-CoV-2 variants. We compared performance 10 commercially available, emergency use authorized against Delta and Omicron variants using both individual patient serially diluted pooled clinical samples. The exhibited lower sensitivity samples when PCR cycle threshold (C

Upper respiratory samples for SARS-CoV-2 detection include the gold standard nasopharyngeal (NP) swab, and mid-turbinate (MT) nasal swabs, oropharyngeal (OP) saliva. Following emergence of omicron (B.1.1.529) variant, limited preliminary data suggest that OP swabs or saliva may be more sensitive than highlighting need to understand differences in viral load across different sites.MT, OP, were collected from symptomatic individuals presenting evaluation Atlanta, GA, January 2022. Longitudinal...
As the emergence of SARS-CoV-2 variants brings global pandemic to new levels, performance current rapid antigen tests against concern and interest (VOC/I) is significant public health concern. Here, we report assessment Abbot BinaxNOW COVID-19 Antigen Self-Test. Using genetically sequenced remnant clinical samples collected from individuals positive for SARS-CoV-2, assessed that currently pose threats. We measured limit detection various VOC/I in a blinded manner. successfully detected...
Abstract With today’s pace of rapid technological advancement, many patient issues in modern medicine are increasingly solvable by mobile app solutions, which also have the potential to transform how clinical research is conducted. However, critical challenges development process impede bringing these translational technologies patients, caused large part lack knowledge among clinicians and biomedical researchers “what it takes” design, develop, maintain a successful medical app. Indeed,...

Widespread use of over-the-counter rapid diagnostic tests for SARS-CoV-2 has led to a decrease in availability clinical samples viral genomic surveillance. As an alternative sample source, we evaluated RNA isolated from BinaxNOW swabs stored at ambient temperature rRT-PCR and full genome sequencing. 81 103 (78.6%) yielded detectable RNA, 46 57 (80.7 %) complete sequences. Our results illustrate that extracted used Binax test provides important opportunity improving surveillance, evaluating...
The motivation for this work was the need to establish a predefined cutoff based on genome copies per ml (GE/ml) rather than Ct, which can vary depending laboratory and assay used.
