Coronavirus disease 2019 (COVID-19) is an infectious disease with a wide range of respiratory and extrapulmonary symptoms, as well as gastrointestinal symptoms.Despite recent research linking gut microbiota to infectious diseases like influenza, minimal information is known about the gut microbiota’s function in COVID-19 pathogenesis. Studies suggest that dysbiosis of the gut microbiota and gut barrier dysfunction may play a role in COVID-19 pathogenesis by disrupting host immune homeostasis. Regardless of whether patients had taken medication or disease severity, the gut microbiota composition was significantly altered in COVID-19 patients compared to non-COVID-19 individuals. Several gut commensals with recognized immunomodulatory potential, such as Faecalibacterium prausnitzii, Eubacterium rectale, and bifidobacteria, were underrepresented in patients and remained low in samples taken several weeks after disease resolution. Furthermore, even with disease resolution, dysbiosis in the gut microbiota may contribute to chronic symptoms, underscoring the need to learn more about how gut microbes play a role in inflammation and COVID-19.

Purpose: The System for Improving and Measuring Procedure Learning (SIMPL), a smartphone-based operative assessment application, was developed to assess the intraoperative performance of surgical residents. This study aims to examine the reliability of the SIMPL assessment and determine the optimal number of procedures for a reliable assessment. Methods: In this retrospective observational study, we analyzed data collected between 2015 and 2023 from 4,616 residents across 94 General Surgery Residency programs in the United States that utilized the SIMPL smartphone application. We employed multivariate generalizability theory and initially conducted generalizability studies to estimate the variance components associated with procedures. We then performed decision studies to estimate the reliability coefficient and the minimum number of procedures required for a reproducible assessment. Results: We estimated that the reliability of the assessment of surgical trainees’ intraoperative autonomy and performance using SIMPL exceeded 0.70. Additionally, the optimal number of procedures required for a reproducible assessment was 10, 17, 15, and 17 for postgraduate year (PGY) 2, PGY 3, PGY 4, and PGY 5, respectively. Notably, the study highlighted that the assessment of residents in their senior years necessitated a larger number of procedures compared to those in their junior years. Conclusion The study demonstrated that the SIMPL assessment is reliably effective for evaluating the intraoperative performance of surgical trainees. Adjusting the number of procedures based on the trainees’ training stage enhances the assessment process’s accuracy and effectiveness.

Background: Antimicrobial resistance has emerged as a global public health challenge, leading to higher mortality rates from infections that were once treatable with antibiotics. In this study, we assessed the susceptibility of Escherichia coli strains isolated from clinical samples to carbapenems and fluoroquinolones and screened for genetic determinants mediating resistance. Materials and Methods: This retrospective study included 46 E. coli isolates retrieved from the stock culture collection at the Molecular Biology and Biotechnology Department of the Nigerian Institute of Medical Research.Antimicrobial susceptibility testing was performed using the Kirby-Bauer disc diffusion method, and molecular techniques were employed to detect genetic determinants of antimicrobial resistance. Results: The E. coli isolates exhibited high resistance to fluoroquinolones, with 72% resistant to ciprofloxacin and 52% to levofloxacin. Resistance to carbapenems was relatively low, with 4% resistant to imipenem and 11% to meropenem. The prevalence of the genetic determinants gyrA, gyrB, and parC, which mediate fluoroquinolone resistance, was 26%, 24%, and 15%, respectively. bla OXA-48 and bla NDM , which mediate carbapenem resistance, were detected in only two isolates. Some isolates harbored plasmids ranging from 5 kb to 16 kb; however, no plasmidmediated genetic determinants conferring fluoroquinolone resistance were identified. Conclusion This study revealed a high level of resistance to fluoroquinolones, emphasizing the need for judicious use of antibiotics, particularly those with low resistance rates. Continuous surveillance is essential to monitor emerging trends in resistance among bacterial pathogens.
