AI Article Synopsis

  • The study focused on female sex workers (FSW) in Amsterdam to understand the risk of chlamydia and gonorrhoea based on their work locations, analyzing data from 2011 to 2016.
  • Significant differences in STI positivity rates were found depending on work location, with those in window prostitution showing lower rates, while escorts and those in clubs/brothels had higher rates.
  • The results indicate a need for targeted interventions to promote condom use and STI testing, especially among higher-risk groups, while suggesting that effective risk reduction strategies can be applied universally across all work locations.

Article Abstract

Unlabelled: Background Female sex workers (FSW) are at risk for sexually transmissible infections (STI). This study aimed to investigate whether the risk for chlamydia and gonorrhoea differs by work location among FSW in Amsterdam. Additionally, trends in STI positivity rates between 2011 and 2016 were assessed.

Methods: This was a retrospective analysis of routinely collected clinical data during STI consultations of FSW by the Prostitution and Healthcare Centre (P&G292). Work location was categorised as window prostitution, escorts/homeworkers, clubs/brothels/private houses/massage salons and other.

Results: In total, 7558 STI consultations of 2529 FSW in the period 2011-16 were included. Positivity rates for chlamydia and gonorrhoea were 6.6% and 2.0%, respectively. Infectious hepatitis B virus, syphilis and HIV were diagnosed in <0.2% of consultations. Positivity rates of chlamydia and rectal gonorrhoea differed significantly by work location (P < 0.001). Genital and rectal chlamydia and rectal gonorrhoea were significantly less likely among women working in window prostitution, except for the other-group. Risk factors for STI did not vary by work location. Among women working in window prostitution, positivity rates for oropharyngeal and genital chlamydia and genital gonorrhoea were significantly decreasing between 2011 and 2016 (P trend <0.05).

Conclusions: The higher STI positivity among escorts/homeworkers and FSW in clubs/brothels/private houses/massage salons emphasises the need for extra attention to improve condom use and STI testing in this group. Factors associated with STI did not vary by work location, thus interventions, including those used by P&G292, to reduce STI risk, can be used for women at all work locations.

Flaviviruses pose a major public health concern across the globe. Among them, Zika virus (ZIKV) is an emerging and reemerging arthropod-borne flavivirus that has become a major international public health problem following multiple large outbreaks over the past two decades. The majority of infections caused by ZIKV exhibit mild symptoms.

Variations in extracellular vesicle shedding of Cystoisospora suis stages (Apicomplexa: Coccidia).

Int J Parasitol

Institute of Parasitology, Department for Biological Sciences and Pathobiology, University of Veterinary Medicine Vienna, Veterinärplatz 1 A-1210 Vienna, Austria.

Cystoisospora suis, a porcine enteral parasite of the order Coccidia, is characterized by a complex life cycle, with asexual and sexual development in the epithelium of the host gut and an environmental phase as an oocyst. All developmental stages vary greatly in their morphology and function, and therefore excrete different bioactive molecules for intercellular communication. Due to their complex development, we hypothesized that the extracellular vesicles (EVs) cargo is highly dependent on the life cycle stages from which they are released.

Background: In sub-Saharan Africa, pediatric and adult treatment programs have not met the needs of youth living with HIV (15-24 years), whose enrollment in antiretroviral treatment (ART) programs is much lower than that of adults. To inform targeted interventions, we analyzed factors associated with ART use among youth in Uganda.

Methods: Data were from 42 communities between 2011 and 2020 (5 survey rounds) from the Rakai Community Cohort Study, an open, population-based cohort.
