Endometrial biopsies were obtained from 32 women with suspected pelvic inflammatory disease, of whom 23 (72%) had histopathological evidence of endometritis. Chlamydia trachomatis was isolated from the endometria of nine (39%) women (chlamydia group) but not from the other 14 (non-chlamydia group). Severe plasma cell endometritis and lymphoid follicles with transformed lymphocytes were significantly more common in the chlamydia group than in the non-chlamydia group. This suggests that C trachomatis is an invasive endometrial pathogen which often causes severe inflammation. The association was independent of predisposing factors such as use of intrauterine contraceptive devices.

Unlabelled: Nucleic acid amplification tests (NAATs) are the method of choice for diagnosis, but these strategies are susceptible to target site mutations. variants escaping detection with the Aptima Combo 2 (AC2) assay on the Hologic Panther instrument from 23S rRNA mutations have been reported in Nordic countries, England, Japan, and the United States. Given the potential for false negative results, this study investigated whether strains of with AC2 target site mutations were present in Canada.

Background: Primary biliary cholangitis (PBC) is a cholestatic, autoimmune liver disease with the presence of characteristic autoantibodies. The aim of the work was to determine the level of antibodies directed against bacterial antigens: (anti-anti), (anti-), (anti- ) and () in sera of PBC patients. We also performed studies on the impact of the bacterial peptides on the specific antigen-antibody binding.

Background: To explore the effect of non-pharmacological interventions (NPIs) on respiratory pathogen profiles among hospitalized infants aged 0-3 months in Beijing during the coronavirus disease 2019 (COVID-19) pandemic.
Methods: Respiratory specimens were collected from 1,184 infants aged 0-3 months who were hospitalized for acute respiratory infection at the Children's Hospital affiliated with the Capital Institute of Pediatrics from January 2018 to December 2023. The data were divided into three groups-the pre-epidemic (January 2018 to December 2019), epidemic prevention and control (January 2020 to December 2022), and post-epidemic (January 2023 to December 2023) groups-based on the outbreak of COVID-19 and the implementation and termination of NPIs.

We aimed to understand to what extent knowledge of the prevalence of one sexually transmitted infection (STI) can predict the prevalence of another STI, with application for men who have sex with men (MSM). An individual-based simulation model was used to study the concurrent transmission of HIV, HSV-2, chlamydia, gonorrhea, and syphilis in MSM sexual networks. Using the model outputs, 15 multiple linear regression models were conducted for each STI prevalence, treating the prevalence of each as the dependent variable and the prevalences of up to four other STIs as independent variables in various combinations.

Introduction: The US state of Florida has the third highest rate of HIV as well as high rates of sexually transmitted infections (STIs) indicating critical HIV and STI prevention needs remain unmet. To address gaps in the STI care continuum in people with HIV (PWH), evidence-based interventions were implemented across three Ryan White HIV/AIDS Program (RWHAP) funded clinics in Florida between August 2020-August 2021. Interventions included comprehensive sexual health history (SHH) taking using audio computer-assisted self-interview (ACASI) software, self-collected extragenital gonorrhea and chlamydia testing, and the introduction of a lesbian, gay, bisexual, transgender, and queer (LGBTQ+) welcoming environment.
