A multiplex gyrB PCR assay has been used to diagnose Acinetobacter baumannii. However, this assay has not been validated against the gold standard DNA-DNA hybridization assay, which is a laborious method. DNA-DNA hybridization assay is now replaced by whole genome sequence (WGS)-based methods. Two such methods are a k-mer-based search of sequence reads using the Kraken 2 program and average nucleotide identity (ANI). The objective was to validate the gyrB PCR assay with WGS-based methods. ⋯ The gyrB PCR assay is now validated for easy identification of A. baumannii in comparison with gold standard WGS-based assays.

We aimed to describe the clinical characteristics of SARS-CoV-2 infection and estimate viral shedding duration in respiratory specimens. ⋯ Predictors for prolonged RT-PCR positivity included increasing age, ARDS, and low white blood cell count. The findings of this study may aid in better understanding of the epidemiology of SARS-CoV-2 infection and molecular testing dynamics.

Although acetaminophen is one of the most widely used over-the-counter drugs, the mechanisms by which this classical drug exerts analgesic, hepatotoxic, and nephrotoxic effects remain unclear. We hypothesized that acetaminophen might act on cellular membranes of nerves, liver, and kidneys. In order to verify this hypothesis, we studied the interactivity of acetaminophen with biomimetic lipid bilayer membranes by comparing with structurally related phenacetin. ⋯ In comparison with phenacetin, lipid composition-dependent membrane interactivity of acetaminophen could be related to nephrotoxicity but not to analgesic activity and hepatotoxicity.

The aim of this study was to determine the bacterial profile and prevalence of antibiotic resistance patterns of uropathogens, as well as to evaluate the problem with extended-spectrum β-lactamases (ESBLs)-producing isolates, causing urinary tract infections (UTIs) in children in Al-Amiri Hospital, Kuwait, over a 5-year period. ⋯ E. coli remains the most common uropathogen. A high percentage of uropathogens causing UTI in children were highly resistant to the first- and second-line antibiotics for the therapy of UTI. ESBL-producing bacteria were highly prevalent in children in our hospital. Local antibiograms should be used to assist with empirical UTI treatment.

The aim of this study was to identify the intensity of COVID-19 symptoms during the pandemic wave during July-September 2021 and to identify factors associated with having moderate and severe symptoms of COVID-19 among affected students in the University of Belgrade. ⋯ Students who are vaccinated against COVID-19 are at lower risk of developing moderate and severe symptoms of the disease.
