Association of Prior SARS-CoV-2 Infection With Risk Breakthrough Following mRNA Vaccination in Qatar
Previous studies of infant fecal samples have failed to clarify the role gut bacteria in pathogenesis NEC. We sought characterize bacterial communities within intestinal tissue resected from infants with and without NEC.26 were 19 infants, including 16 NEC 10 non-NEC samples. Bacterial 16S rRNA gene sequences amplified sequenced. Analysis allowed for taxonomic identification, quantitative PCR was used quantify load samples.NEC generally contained an increased total burden bacteria. sample...
Lumenal obstruction has typically been regarded as the cause of acute appendicitis (AA). Recent evidence including data from "antibiotics first" trials suggests that this disease may result invasion appendix by specific pathogens. Small studies have identified an abundance bacteria genus Fusobacterium in appendixes patients with AA. We aimed to validate these findings a larger cohort children addition profiling appendiceal microbiota population without appendicitis.Appendix swabs were...
The risk of COVID-19 infection is increased in patients with systemic lupus erythematosus (SLE) versus those without SLE. Some immunosuppressive medications increase and decrease the efficacy vaccination. Consensus documents have suggested management strategies for handling to vaccine efficacy, but benefit such has not been proven. current study was undertaken determine effect drugs on response
Abstract Arthropod-borne viruses represent a crucial public health threat. Current arboviral serology assays are either labor intensive or incapable of distinguishing closely related viruses, and many zoonotic arboviruses that may transition to humans lack any serologic assays. In this study, we present programmable phage display platform, ArboScan, evaluates antibody binding overlapping peptides the proteomes 691 human arboviruses. We confirm ArboScan provides detailed information from...

In a large healthcare worker cohort, we quantified the association between behaviors and risk of coronavirus disease 2019 (COVID-19) during different pandemic phases, adjusting for prior infection vaccination. Individual characteristics, including personal concerns, were associated with these behaviors. Public health messaging should target high-risk populations as evolves.
Abstract Background An escape room is a cooperative game that has been adapted into medical education and major academic conferences. Methods We describe the design, development, implementation of an educational ID-themed activity entitled “Out-BREAK!” at international conference, IDWeek 2023. anonymous survey was conducted to collect demographic data, assess participant satisfaction with puzzles, gauge interest in game-based learning. Results Thirty sessions were held over 3 days included...
Abstract Background HIV-positive men who have sex with (MSM) are recommended to anal Pap tests annually screen for high-grade squamous intraepithelial lesions (HSIL). In this population, removal of HSIL reduces the risk progression cancer. This study aims assess effectiveness dysplasia screening cascade in a single-center outpatient clinic. Methods We conducted retrospective cohort at Johns Hopkins. All adult MSM patients had in-person encounters Bartlett Clinic between October 1, 2019-April...
Abstract Background Zika virus (ZIKV) is a flavivirus associated with serious congenital syndrome, recent epidemic originating in Brazil 2015. Novel ZIKV vaccine candidates are development. We report results of phase I study the first live attenuated for use humans. rZIKV/D4Δ30-713 chimeric vaccine, expressing premembrane (prM) and envelope (E) genes contemporary strain within dengue DEN4Δ30 background. Methods conducted I, randomized, placebo-controlled double-blind trial, evaluating two...
Abstract Waning serum antibodies against SARS-CoV-2 have sparked discussions about long-term immunity and need for vaccine boosters. We examined spike IgG in a longitudinal cohort, comparing antibody decay individuals who received an mRNA vaccine, with without prior infection. completed cohort of healthcare workers (HWs) between June 2020 September 2021. HWs were included if they had sample collected after infection and/or ≥ 14 days second dose vaccine. Linear regression models adjusting...
<h3>Background</h3> The risk of COVID-19 infection is increased in patients with systemic lupus erythematosus (SLE), and immunosuppressive medications including corticosteroids impact the risk. Furthermore, may reduce effectiveness vaccination. Consensus documents have suggested management strategies on handling to increase vaccine efficacy, but benefit such has not been proven. <h3>Methods</h3> We collected information COVID infection, vaccination history, antibodies Hopkins Lupus Cohort, a...
