Article Abstract
Background: Chronic urticaria (CU) is a common skin disease; however, its etiology is rarely recognized. Infection due to (. ) has been shown in some studies to play a significant role in the pathogenesis of CU.
Objective: This study was conducted to determine the association between CU and . infection among patients attending the Regional Dermatology Training Center, Northern Tanzania, from October 2018 to April 2019. . A matched case-control study that included 55 cases and 55 controls matched by age and sex was conducted. Data were collected through direct interviews, and the results of laboratory investigations were recorded in the extraction sheet. An enzyme-linked immunosorbent assay test was used to detect . antigen in the stool samples. Conditional logistic regression was used to measure the association between CU and . .
Results: The total number of participants in this study was 110 patients (55 cases and 55 controls), whereby the median age was 31 (IQR 27-45) among controls versus 34 (IQR: 22-46) years among the cases. Both cases and controls had the same number of females and males. There was no significant association between CU and baseline characteristics of the participants. There was an association between CU and . infection, such that subjects with CU had a higher number of positive . test (15/55 = 27%) versus controls (6/55 = 10.1%) ( = 0.0225). The adjusted odds of CU among patients who were positive for . were sixfolds higher (OR = 6.9; CI: 1.3-36.2; = 0.021) than those of patients who were negative for
Conclusion: There was a strong and significant association between CU and . infection. We recommend investigating for . in all cases of CU and conducting further trials on . eradication.

This review explores the bidirectional relationship between the human microbiome and SARS-CoV-2 infection, elucidating its implications for COVID-19 susceptibility, severity, and therapeutic strategies. Metagenomic analyses reveal notable alterations in microbiome composition associated with SARS-CoV-2 infection, impacting disease severity and clinical outcomes. Dysbiosis within the respiratory, gastrointestinal, oral, and skin microbiomes exacerbates COVID-19 pathology through immune dysregulation and inflammatory pathways.

Background: CD4+ T cells expressing α4β7 are optimal targets for HIV infections, with higher pre-HIV α4β7hi expression linked to increased HIV acquisition and progression in South African women. However, similar associations were not observed in men who have sex with men (MSM) or people who inject drugs (PWID) in the Americas, indicating need for further research.
Methods: This retrospective case-control study enrolled heterosexual men and women from South Africa (HIV Vaccine Trials Network; HVTN 503) and East Africa (Partners Pre-Exposure Prophylaxis/Couples' Observational Study; PP/COS), quantifying α4β7 expression on CD4+ T cells as a predictor of subsequent HIV risk using flow cytometry analyses.
Effect of Time to Surgery on Surgical Site Infection in Open Distal Radius Fractures: A Review of the ACS Trauma Quality Improvement Program Database.

Introduction: Managing open distal radius fractures (DRFs) poses challenges. While preventing surgical site infection (SSI) involves prompt antibiotic administration and thorough irrigation and debridement, the impact of urgent intervention on reducing postoperative infection rates is debated. We hypothesize that timing of surgery does not significantly affect the incidence of SSI in open DRF treated within or after 24 hours from time of injury.
