Vaginal Dysbiosis in Infertility: A Comparative Analysis Between Women with Primary and Secondary Infertility.

Unlabelled: Infertility, both primary and secondary, is strongly influenced by microbiological factors, with the vaginal microbiota playing a key role in reproductive health.

Objective: The aim of this study was to characterize the vaginal microbiota of 136 Mexican women diagnosed with infertility-primary (n = 58) and secondary (n = 78)-by evaluating the presence of pathogenic bacterial species and their associations with infertility conditions.

Methods: Samples were obtained through cervical swabs, and microorganism identification was performed using qPCR techniques.

Epidemiology of reinfections by SARS-CoV-2 variants during the third and fourth waves of the COVID-19 pandemic.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic is a global health concern and has persisted through the emergence of variants that have caused subsequent waves of COVID-19 due to the high dispersion and contagiousness of the virus. The aim of this work was to analyze the epidemiology of the cases of reinfection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants during the third and fourth wave of the COVID-19 pandemic at the Hospital Juárez de México (HJM).

Methodology: A prospective study of the cases of SARS-CoV-2 reinfection, variants detected, symptoms, and associated comorbidities was carried out on 1,347 patients who attended the HJM from September 2021 to July 2022.

Is Associated with Cervicovaginal Infections and Human Papilloma Virus in Cervical Disease of Mexican Female Patients.

, traditionally considered an environmental bacterium, has recently garnered attention for its potential involvement in human health. While prior research hinted at its pathogenic role in humans, our study aims to determine its prevalence and associations in diverse clinical contexts. We examined vaginal swabs from three distinct patient groups: patients with low-grade squamous intraepithelial lesions (LSIL), patients with cervicovaginal infections, and patients with a history of precancerous lesions undergoing follow-up.

Ozone as an alternative decontamination process for N95 facemask and biosafety gowns.

COVID-19 pandemic created a global shortage of medical protective equipment. Here, we considered ozone (O) a disinfectant alternative due to its potent oxidative activity against biological macromolecules. The O decontamination assays were done using SARS-CoV-2 obtained from patients to produce artificial contamination of N95 masks and biosecurity gowns.
