Abstract Background Previous meta-analyses estimating the prevalence of post-COVID-19 condition (PCC) were confounded by lack negative control groups. This may result in an overestimation those experiencing PCC, as these symptoms are non-specific and common general population. In this study, we aimed to compare burden persistent among COVID-19 survivors relative COVID-19-negative controls. Methods A systematic literature search was conducted using following databases (PubMed, Web Science,...

Abstract Background This study analyzes trends in HIV-related mortality disparities between Black and White populations the USA from 1999 to 2023. Methods CDC WONDER data were utilized assess absolute disparities, measured as age-adjusted rate difference, relative ratio, Black-White HIV mortality. Trends analyzed using Joinpoint regression, with average annual percentage change (AAPC) serving a summary measure for entire period (APC) used evaluate magnitude of within specific intervals....

The exposure of bacteria to sub-inhibitory concentrations antibiotics is biological significance since it can occur in vivo under many circumstances, including low-dose treatment, poor adherence a regimen, drug penetration, drug-drug interactions, and antibiotic resistance the pathogen. In this study, we investigated effects subinhibitory four antibiotics: ampicillin, ceftriaxone, gentamicin, norfloxacin, which are commonly used clinical settings on cell morphology biofilm formation...

BACKGROUND: Circulating tumor DNA (ctDNA) is a promising non-invasive marker for detection, diagnosis, treatment selection, and prognosis of hepatocellular carcinoma (HCC). OBJECTIVE: This study aimed to examine the utility ctDNA as prognostic predictive tool in HCC patients treated with nivolumab. METHODS: We analyzed pre-treatment from 44 using comprehensive genomic testing on commercially available platform. utilized log rank test univariate Cox models correlate overall survival (OS)...

<title>Abstract</title> <bold>Objective</bold> Previous meta-analyses have demonstrated that vancomycin-resistant Enterococcus (VRE) bacteremia is associated with increased mortality compared to vancomycin-sensitive (VSE) bacteremia. However, these studies relied on unadjusted data, which could potentially lead an overestimation of the risk. Therefore, we performed this systematic review meta-analysis investigate impact vancomycin resistance adverse outcomes in enterococci blood stream...
