In a prospective cohort of healthcare personnel (HCP), we measured severe acute respiratory syndrome coronavirus virus 2 (SARS-CoV-2) nucleocapsid IgG antibodies after SARS-CoV-2 infection. Among 79 HCP, 68 (86%) were seropositive 14-28 days after their positive PCR test, and 54 (77%) of 70 were seropositive at the 70-180-day follow-up. Many seropositive HCP (95%) experienced an antibody decline by the second visit.

Analysis Of Variation In Pre-Procedural Fasting Duration For Common Inpatient Gastrointestinal Procedures, Vorada Sakulsaengprapha, Michael Daniel, Jiarui Cai, Diego A. Martinez, Simon C. Mathews

2020-Current year OA Pubs

BACKGROUND: Gastrointestinal procedures generally require pre-procedural fasting to optimize sedation safety. While the American Society of Anesthesiologists (ASA) recommends no intake of clear liquids and solid food 2-4 and 6-8 hours respectively prior to endoscopic procedures, the actual nil per os (NPO) duration for these procedures in practice is unknown. Our objective was to analyze NPO duration for patients undergoing these procedures and to determine its association with clinical and administrative variables.

METHODS: Inpatient data from 2016-2018 for the three procedures was extracted from electronic medical records and administrative data at a single-center tertiary academic medical center. Various statistical tests …

This form of capital prioritizes brain skills and brain health in a brain economy, which the challenges and opportunities of the 21st-century demands. This approach incorporates investing in late-life Brain Capital, developing initiatives focused …

Semi-Quantitative Assay To Measure Urease Activity By Urinary Catheter-Associated Uropathogens, Jesus M Duran Ramirez, Jana Gomez, Chloe L P Obernuefemann, Nathaniel C Gualberto, Jennifer N Walker

2020-Current year OA Pubs

Catheter-associated urinary tract infections (CAUTIs) are one of the most common healthcare-associated infections in the US, accounting for over 1 million cases annually and totaling 450 million USD. CAUTIs have high morbidity and mortality rates and can be caused by a wide range of pathogens, making empiric treatment difficult. Furthermore, when urease-producing uropathogens cause symptomatic CAUTI or asymptomatic catheter colonization, the risk of catheter failure due to blockage increases. The enzyme urease promotes catheter blockage by hydrolyzing urea in urine into ammonia and carbon dioxide, which results in the formation of crystals that coat the catheter surface. If CAUTI is …

2020-Current year OA Pubs

Acute promyelocytic leukemia (APL) often presents with significant coagulopathy which may result in both hemorrhagic and thrombotic complications. The emergence of the COVID-19 pandemic has complicated the initial treatment and diagnosis of APL owing to the viral infection's own associated coagulopathy. Here we report two cases of APL newly diagnosed in the setting of COVID-19 infection and considerations in their management. Included is a discussion of strategies for the dosing of arsenic trioxide in patients with significant obesity and renal insufficiency. The case series submitted does not represent a study on patients and thus no specific informed consents or permissions …

Detection Of Emerging Neurodegeneration Using Bayesian Linear Mixed-Effect Modeling, Yann Cobigo, Richard J Perrin, Et Al.

2020-Current year OA Pubs

Early detection of neurodegeneration, and prediction of when neurodegenerative diseases will lead to symptoms, are critical for developing and initiating disease modifying treatments for these disorders. While each neurodegenerative disease has a typical pattern of early changes in the brain, these disorders are heterogeneous, and early manifestations can vary greatly across people. Methods for detecting emerging neurodegeneration in any part of the brain are therefore needed. Prior publications have described the use of Bayesian linear mixed-effects (BLME) modeling for characterizing the trajectory of change across the brain in healthy controls and patients with neurodegenerative disease. Here, we use an extension …

Circulating-tumor DNA (ctDNA) has emerged as an important biomarker for monitoring disease status in cancer patients. Different ctDNA testing platforms have shown promising results in the early detection of disease, monitoring response to treatment, and prognostication in metastatic melanoma. However, several challenges exist, including the reduced shedding of ctDNA into the bloodstream in the metastatic setting, differences in sensitivity among various ctDNA assays, and the inherent inability to distinguish tumor-specific mutations from other mutations that are not related to the cancer of interest. Using a ctDNA assay that is designed to detect multiple single-nucleotide variants (SNVs) that are specific to …

Islet Cilia And Glucose Homeostasis, Isabella Melena, Jing W Hughes

2020-Current year OA Pubs

Diabetes is a growing pandemic affecting over ten percent of the U.S. population. Individuals with all types of diabetes exhibit glucose dysregulation due to altered function and coordination of pancreatic islets. Within the critical intercellular space in pancreatic islets, the primary cilium emerges as an important physical structure mediating cell-cell crosstalk and signal transduction. Many events leading to hormone secretion, including GPCR and second-messenger signaling, are spatiotemporally regulated at the level of the cilium. In this review, we summarize current knowledge of cilia action in islet hormone regulation and glucose homeostasis, focusing on newly implicated ciliary pathways that regulate insulin …

Four Decades Of Mapping And Quantifying Neuroreceptors At Work In Vivo By Positron Emission Tomography, Albert Gjedde, Dean F Wong

Emerging Themes In The Molecular Pathogenesis Of Enterotoxigenic Escherichia Coli, James M Fleckenstein, Alaullah Sheikh

2020-Current year OA Pubs

Enterotoxigenic Escherichia coli (ETEC) are ubiquitous diarrheal pathogens that thrive in areas lacking basic human needs of clean water and sanitation. These genetically plastic organisms cause tremendous morbidity among disadvantaged young children, in the form of both acute diarrheal illness and sequelae of malnutrition and growth impairment. The recent discovery of additional plasmid-encoded virulence factors and elucidation of their critical role in the molecular pathogenesis of ETEC may inform new approaches to the development of broadly protective vaccines. Although the pathogens have been closely linked epidemiologically with nondiarrheal sequelae, these conditions remain very poorly understood. Similarly, while canonical effects of …

This is a review of research on "Precision Behavioral Management" of substance use disorder (SUD). America is experiencing a high prevalence of substance use disorder, primarily involving legal and illegal opioid use. A 3000% increase in treatment for substance abuse has occurred between 2000 and 2016. Unfortunately, present day treatment of opioid abuse involves providing replacement therapy with powerful opioids to, at best, induce harm reduction, not prophylaxis. These interventions do not enhance gene expression and restore the balance of the brain reward system's neurotransmitters. We are proposing a generalized approach called "Precision Behavioral Management". This approach includes 1) using …
