Trans-inclusive Sexual Health Questionnaire to Improve HIV/STI Care for Transgender Patients: Anatomic-site Specific STI Prevalence & Screening Rates.

Clin Infect Dis 2022 May 20. Epub 2022 May 20.

Public Health-Seattle & King County HIV/STD Program, Seattle, WA, USA.

Background: In 2018, the municipal Sexual Health Clinic in Seattle implemented trans-inclusive questions about sexual behavior, anatomy, gender-affirming surgeries, and STI symptoms in the clinic's computer-assisted self-interview (CASI) to improve care for transgender and non-binary (TNB) patients.

Methods: We calculated test positivity and the proportion of TNB patient visits that received testing for HIV, syphilis, pharyngeal, rectal and urogenital gonorrhea (GC) and chlamydia (CT) before (5/2016-12/2018) and after (12/2018-2/2020) implementation of new CASI questions. We then calculated the proportion of asymptomatic patients who received anatomic-site specific screening based on reported exposures. Read More

Insights into Microsporidia Evolution from Early Diverging Microsporidia.

Authors:
Daniele Corsaro

Exp Suppl 2022 ;114:71-90

CHLAREAS Chlamydia Research Association, Vandoeuvre-lès-Nancy, France.

Microsporidia have drastically modified genomes and cytology resulting from their high level of adaptation to intracytoplasmic parasitism. Their origins, which had long remained enigmatic, were placed within the line of Rozella, a primitive endoparasitic chytrid. These origins became more and more refined with the discovery of various parasites morphologically similar to the primitive lines of microsporidia (Metchnikovellids and Chytridiopsids) but which possess fungal-like genomes and functional mitochondria.

Department of Medical Microbiology, Care and Public Health Research Institute (Caphri), Maastricht University Medical Center, Maastricht, The Netherlands.

Reports of potential treatment failure have raised particular concerns regarding the efficacy of the single dose azithromycin regimen in the treatment of urogenital and anorectal Chlamydia trachomatis (CT) infections. Several factors have been suggested, including heterotypic resistance. Antimicrobial susceptibility testing in CT requires cell culture with serial dilutions of antibiotics, which is laborious and for which there is no standardized testing methodology. Read More
