Abstract
We report the case of a 23-year-old patient with very marked hepatic cytolysis (ASAT: 18N; ALAT: 44N) associated with biological icterus and mucocutaneous jaundice. Initially, no etiology was identified due to the absence of toxic consumption, the negativity of hepatotropic virus serologies and tests for autoimmune pathologies. Following the appearance of cutaneous signs three weeks after the onset of hepatic involvement, a syphilis serology was performed, which proved positive and led to the diagnosis of secondary syphilis. To our knowledge, only one case of hepatic syphilis with such intense hepatic cytolysis has been described. Usually, the hepatic damage is moderate, with transaminases not exceeding 5 times normal values. Syphilitic hepatitis is rare and occurs in less than 10% of syphilis cases. This case makes it possible to identify syphilis as a neglected etiology of acute hepatitis which should be considered in a context suggestive of infection even in the absence of skin signs.

Abstract
In recent years, the rapid development of information and communication technology (ICT) and the influence of the novel coronavirus (COVID-19) have affected our lives and work in various fields such as medical and welfare, construction and manufacturing and education, etc. With this global background, teleconference systems have received attention and become a new trend. However, the acoustics of rooms using teleconference system often overlap the acoustic characteristics from multiple rooms on both the speaker and listener sides. Therefore, it can sometimes be difficult to listen to each other. A prior study suggested that the installation of sound-absorbing panels improves intelligibility and reduces the listening difficulty for young people. However, elderly people must be included in the target owing to the effects of aging. This study aimed to clarify improvements in the subjective assessments of elderly people in a room where a teleconference system is used. In addition, the differences in subjective assessments between young people and elderly people were also investigated. The results of an experiment indicate that, first, a room using a teleconference system demonstrated a greater improvement in subjective assessments after the acoustic improvements compared to the same room where face-to-face meetings. Second, the subjective assessments and improvements of them for elderly people differed greatly since older user had listening habits and experiences that varied from those of young people.

Abstract
BACKGROUND In open-plan office rooms, one of the main reasons for the nuisance of work is the noise from employees' conversations. In order to limit it, the permissible values of the parameters characterizing the acoustic properties in those rooms on a 2-level scale are defined. MATERIAL AND METHODS The article introduces a 3-level scale for assessing the acoustic properties (bad, fair, good) of a room based on EN ISO 3382‑3:2012 and PN-B-02151-4:2015 - criterion 1. Additionally and alternatively, a new 3-level scale assessment criterion (criterion 2), concerning acoustic separation between groups of workstations, was determined. In order to meet that criterion, it is necessary to take into account the acoustic treatment of the room. A multivariate (7) acoustic treatment studies were performed using computational simulation methods. RESULTS Requirements, according to PN-B-02151-4:2015, were met after the application of a sound-absorbing suspended ceiling and acoustic screens at workplaces. To meet the requirements of EN ISO 3382‑3:2012, it was necessary to additionally use sound-absorbing materials on the walls and acoustic screens separating the naves of the room. To meet the requirements of criterion 2, it was necessary to additionally use acoustic screens separating groups of workstations and acoustic screens in passages. CONCLUSIONS Appropriate acoustic properties can be obtained in open space offices. Appropriate acoustic properties can be obtained in open-space offices. The requirements according to PN-B-02151-4:2015 can be met with much lower acoustic treatment than the requirements according to EN ISO 3382‑3:2012. The use of a 3-level scale for assessing the acoustic properties of a room allows for the differentiation of rooms with regard to their acoustic properties. The introduction of a new assessment method, taking into account the grouping of workplaces in a room, makes it possible to assess the acoustic properties of a room in a more reliable way, by neglecting the impact on the assessment of areas where people are not present.

Abstract
Objetivos . Mycoplasma genitalium causa infecciones de transmisión sexual persistentes/recurrentes. El objetivo de este trabajo fue estimar la prevalencia y resistencia a azitromicina de M. genitalium en pacientes de Atención Primaria del Área Sanitaria de Santiago de Compostela. Material y métodos Se estudiaron pacientes atendidos en Atención Primaria del Área Sanitaria de Santiago de Compostela en 2019. El cribado de patógenos de transmisión sexual y la detección de mutaciones en el gen ARNr 23S se hicieron por PCR en tiempo real. Resultados . Se estudiaron 502 mujeres y 532 hombres. La prevalencia de M. genitalium fue 2,4% en hombres y 2,9% en mujeres. La tasa de resistencias a azitromicina fue del 20%, todas detectadas en hombres. Las mutaciones encontradas fueron A2059G, A2058G y A2058T. Conclusiones Aunque el porcentaje de infecciones por M. genitalium es bajo, la elevada tasa de resistencia frente a azitromicina hace necesario actualizar los protocolos de diagnóstico y tratamiento de las infecciones de transmisión sexual, tanto para mejorar su resolución como para evitar la aparición de resistencias en otros patógenos del tracto urogenital.

How do biases in sex ratio and disease characteri stics affect the spread of sexually transmitted infections? J Theor Biol 2021; 527:110832.

Abstract
The epidemiology of sexually transmitted infections (STIs) is inherently linked to host mating dynamics. Studies across many taxa show that adult sex ratio, a major determinant of host mating dynamics, is often skewed - sometimes strongly - toward males or females. However, few predictions exist for the effects of skewed sex ratio on STI epidemiology, and none when coupled with sex biased disease characteristics. Here we use mathematical modelling to examine how interactions between sex ratio and disease characteristics affect STI prevalence in males and females. Notably, we find that while overall disease prevalence peaks at equal sex ratios, prevalence per sex peaks at skewed sex ratios. Furthermore, disease characteristics, sex-biased or not, drive predictable differences in male and female STI prevalence as sex ratio varies, with higher transmission and lower virulence generally increasing differences between the sexes for a given sex ratio. Our work reveals new insights into how STI prevalence in males and females depends on a complex interaction between host population sex ratio and disease characteristics.

Abstract
Background Antenatal screening for HIV, syphilis and HBV has been successfully implemented in The Netherlands, but data on other STI among pregnant women or male partners are limited. Our objectives: (i) to assess the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) among pregnant women and male partners, (ii) to identify risk factors for these STI during pregnancy, and (iii) to identify adverse perinatal outcomes (APO) associated with STI. Methods Cross-sectional study. Pregnant women aged ≤ 30 years (n = 548) and male partners (n = 425) were included at 30 midwifery practices during 2012–2016. Participants provided a self-collected vaginal swab (women) or urine sample (men) and completed a questionnaire. Perinatal data were derived from pregnancy cards. APO was defined as premature rupture of membranes, preterm delivery, low birthweight, stillbirth, neonatal conjunctival and respiratory infections. Data were analysed by logistic regression. Results STI were present in 2.4% of pregnant women (CT 1.8%, NG 0.4%, TV 0.4%), and in 2.2% of male partners (CT 2.2%, NG 0.2%, TV 0%). Of young women (≤ 20 years), 12.5% had a CT infection. Prevalent STI during pregnancy was associated with female young age (≤ 20 years vs ≥ 21 years) (adjusted OR 6.52, CI 95%: 1.11–38.33), male non-Western vs Western background (aOR 9.34, CI 2.34–37.21), and female with ≥ 2 sex partners < 12 months vs 0–1 (aOR 9.88, CI 2.08–46.91). APO was not associated with STI, but was associated with female low education (aOR 3.36, CI 1.12–10.09), complications with previous newborn (aOR 10.49, CI 3.21–34.25 vs no complications) and short duration (0–4 years) of relationship (aOR 2.75, CI 1.41–5.39 vs ≥ 5 years). Small-for-gestational-age was not associated with STI, but was associated with female low education (aOR 7.81, 2.01–30.27), female non-Western background (aOR 4.41, 1.74–11.17), and both parents smoking during pregnancy (aOR 2.94, 1.01–8.84 vs both non-smoking). Conclusions Prevalence of STI was low among pregnant women and male partners in midwifery practices, except for CT among young women. The study could not confirm previously observed associations between STI and APO, which is probably due to low prevalence of STI, small study sample, and presumed treatment for STI. Supplementary Information The online version contains supplementary material available at 10.1186/s12978-021-01179-8. Antenatal screening for HIV, syphilis and HBV has been successfully implemented in The Netherlands, but data on other STI among pregnant women or male partners are limited.

Abstract
Each year Canada approves about 70,000 agricultural temporary foreign worker positions. However, few studies have examined temporary foreign workers' sexual health. In this mixed-methods study, we used surveys and focus groups to explore the knowledge of HIV and sexually transmitted infections (STI), sexual behaviours and the perspectives of sexual health of 100 Thai and Filipino temporary foreign workers in southwestern Ontario, Canada. The findings revealed that transnational migration had opened up social space that workers were not familiar with. Social isolation, stress and prolonged separation from spouses and partners resulted in the formation of new intimate relationships. Close to two-thirds of the 100 participants were sexually active in the twelve months prior to the study and over three-quarters did not use condoms. Many participants had misconceptions about HIV risks and safer sex practices. Few temporary workers accessed sexual health services due to language barriers, time constraints, stigma and lack of transport. As a result, many obtained medical advice and medicine through their families back home and relied on self-treatment in dealing with symptoms of genital infections. Effective sexual health promotion for temporary foreign workers must consider the complex interactive sociocultural and political processes that involve institutional practices in the local and transnational contexts.

Abstract
In this study, we investigated spatial diversities of sexually transmitted infections (STIs) and quantified their impacts on the STIs using population attributable risk (PAR%). The study population was 7,557 women who participated in several HIV prevention trials from KwaZulu-Natal, South Africa. Our results provide compelling evidence for substantial geographical diversities on STI incidence rates in the region. Their population-level impacts on the STIs exceeded the combined impacts of the individual risk factors considered in this study (PAR%: 41% (<25 years), 52% (25-34 years) and 34% (35+ years). When all these factors are considered together, PAR% was the highest among younger women (PAR%: 67%, 82% and 50% for <25, 25-34 and 35+ years old respectively). Results from our study will bring greater insight into the previous research by increasing our understanding of the impacts of the sub-geographical level variations of STI prevalence and incidence rates in the region.

Abstract
Pre-exposure prophylaxis (PrEP) is a new preventive treatment for individuals at high-risk for HIV infection, such as men who has sex with men (MSM). Studies have confirmed the efficacy but concerns about the potential induction of risk compensation remains. We aimed to assess the incidence of sexually transmitted infections (STIs) after PrEP initiation as a proxy for sexual risk behavior. This case-crossover study used data from medical records and from the Danish Microbiology Database from patients who initiated PrEP at the Region of Southern Denmark between 2017 and 2019. Poisson regression was used to assess STI incidence 6 months after PrEP initiation versus the 6 months before. To identify potential risk factors, we compared individuals with an increased STI incidence after PrEP initiation with those without, using logistic regression. In total, 46 MSM initiated PrEP in the study period. We found a significant increase in the number of positive samples for STI after PrEP initiation (IRR 1.83; 95% CI [1.03, 3.26]) and a tendency for higher incidence of STI episodes (1.67; 95% CI [0.91, 3.13]). The increase was concentrated to a group of users, but no significant correlation was found between increasing incidence and the baseline factors examined. We observed a degree of risk compensation after the implementation of PrEP among MSM, clustering to a group of users. Our results highlight the importance of frequent STI screening among MSM on PrEP as timely diagnosis could contribute to an overall decrease in STI incidence and incidence among MSM.

Abstract
PURPOSE Substance use and sexual risk-taking have been shown to co-occur. Programs focused on sexually transmitted infections (STIs) reduction may benefit substance-using, particularly binge substance-using, adults. This is especially true for rural Native American communities who endure sexual and substance use disparities and have few STI risk reduction programs. This study explores factors predicting retention in an STI risk reduction program among rural Native adults engaged in binge substance use. METHODS We analyzed data from 150 Native adults ages 18-55 participating in an evaluation of "EMPWR," a 2-session STI risk reduction program in a rural, reservation-based community. Multivariate logistic regression models were used to estimate associations between independent variables and program completion across demographics, sexual behaviors, substance use behaviors, mental health, recent health care utilization, and perceived enculturation and discrimination. FINDINGS The sample was 49.2% (n = 59) female with a mean age of 33.61 years (SD = 8.25). Twenty-six completed only the first EMPWR session, 94 completed both EMPWR sessions, and 30 were randomized but completed 0 sessions. Being married/cohabiting (adjusted odds ratio [AOR] = 6.40, P = .0063) and living with an older generation (AOR = 4.86, P = .0058) were significantly associated with higher odds of completing EMPWR. CONCLUSIONS Findings provide insight on factors driving retention of Natives with recent binge substance use in STI risk reduction programming. An important contribution to Native health literature is that living with an older generation positively predicted EMPWR program completion, suggesting that STI risk reduction programs should harness the strength of families to ensure program attendance and optimize impacts in rural reservation contexts.

Abstract
BACKGROUND Identifying predictors of preterm birth (PTB) in high burden regions is important as PTB is the leading cause of global child mortality. METHODS This analysis was nested in a longitudinal study of peripartum HIV incidence in Kenya. HIV-seronegative women enrolled in pregnancy were screened with nucleic acid amplification tests (chlamydia and gonorrhea), RPR (syphilis), wet mount microscopy (Trichomonas and yeast), and Gram stain (bacterial vaginosis); sexually transmitted infection (STI) treatment was provided. PTB predictors were determined using log binomial regression. FINDINGS Among 1244 mothers of liveborn infants, median age was 22 years (IQR 19 - 27), median gestational age at enrollment was 26 weeks (IQR 22 - 31) and at delivery was 39.1 weeks (IQR 37.1 - 40.9). PTB occurred in 302 women (24.3%). Chlamydia was associated with a 1.59-fold (p=0.006), gonorrhea a 1.62-fold (p=0.04) and incident HIV a 2.08-fold (p=0.02) increased prevalence of PTB. Vaginal discharge and cervical inflammation were significantly associated with PTB, as were age ≤21 (prevalence ratio [PR] =1.39, p=0.001) and any STI (PR=1.47, p=0.001). Chlamydia and incident HIV remained associated with PTB in multivariable models. INTERPRETATION STIs and incident HIV in pregnancy predicted PTB despite treatment, suggesting need for earlier treatment and interventions to decrease genital inflammation.

Abstract
Sexually transmitted infections (STIs) represent a worldwide public health problem and, although many of them are curable, they continue to be neglected, especially in areas with a low human development index, such as in the northern region of Brazil. This review describes the results of 30 years of studies at the Virus Laboratory at the Federal University of Pará, including the prevalence and molecular epidemiology of HIV-1, HTLV-1/2, HPV, HBV, Treponema pallidum and Chlamydia trachomatis among urban and non-urban populations, and also in vulnerable groups in the Brazilian Amazon. Control strategies and challenges in preventing STIs are discussed considering this immense geographic region, where essential health services are unable to reach the entire population, especially the most vulnerable, such as female sex workers, people who use illicit drugs, remnants of quilombolos and indigenous communities.

Abstract
Black men who have sex with men (BMSM) have disproportionate HIV/STI acquisition risk. Incarceration may increase exposure to violence and exacerbate psychosocial vulnerabilities, including internalized homophobia, which are associated with HIV/STI acquisition risk. Using data from HIV Prevention Trials Network 061 (N = 1553), we estimated adjusted prevalence ratios (APR) and 95% confidence intervals (CIs) for associations between lifetime burden of incarceration and HIV/STI risk outcomes. We measured associations between incarceration and HIV/STI risk outcomes with hypothesized mediators of recent violence victimization and internalized homophobia. Compared to those never incarcerated, those with 3-9 or ≥ 10 incarcerations had approximately 10% higher prevalence of multiple partnerships. Incarceration burden was associated with selling sex (1-2 incarcerations: APR: 1.52, 95% CI 1.14-2.03; 3-9: APR: 1.77, 95% CI 1.35-2.33; ≥ 10: APR: 1.85, 95% CI 1.37-2.51) and buying sex (≥ 10 incarcerations APR: 1.80, 95% CI 1.18-2.75). Compared to never incarcerated, 1-2 incarcerations appeared to be associated with current chlamydia (APR: 1.47, 95% CI 0.98-2.20) and 3-9 incarcerations appeared to be associated with current syphilis (APR: 1.46, 95% CI 0.92-2.30). Incarceration was independently associated with violence, which in turn was a correlate of transactional sex. Longitudinal research is warranted to clarify the role of incarceration in violence and HIV/STI risk in this population.

Abstract
INTRODUCTION Surveillance for recent HIV infections was implemented at Dutch sexual health centres (SHCs) for planning and evaluation of HIV prevention initiatives. The study objective is twofold: (1) to explore trends in recent HIV infections and associated socio-demographic and behavioural risk factors among men who have sex with men (MSM )attending SHCs, to gain insight into subgroups at risk for acquiring HIV and(2) to illustrate how comparison with different reference groups affect associations with these risk factors. METHODS Residual plasma or serum samples from MSM newly HIV diagnosed at SHCs in 2014-2017 were tested with an avidity assay. Multinomial regression was used to analyse risk factors for recent HIV infections among MSM with established HIV infections among MSM and with HIV-negative MSM as reference groups. RESULTS Of newly diagnosed MSM, 33% were classified as recent HIV infection with avidity testing. Combining HIV-negative test results with avidity outcomes resulted in 54% recent infections. Recent infection was associated with having an STI in the past, multiple partners and condom use for both reference groups of MSM. Additionally, relative to the HIV-negative MSM, recent infection was associated with education and having a non-Western origin. In contrast, relative to MSM with established HIV infections, recent infection was associated with Western origin. CONCLUSION Our results suggest ongoing but declining transmission of HIV and high uptake of HIV testing among MSM visiting SHCs. The identification of risk factors for recent infections can help healthcare professionals to target subgroups eligible for PrEP or condom use promotion. Differentiation by the reference group in explanatory models for recent infections is important as different risk factors were identified. Likely, associations relative to HIV-negative MSM follow those of acquiring HIV infection in general, whereas the comparison with the established HIV infection reference rather reflects the frequent testing behaviour of subgroups of MSM.

Prevalence of Chlamydia trachomatis Among Pregnant Women, Gynecology Clinic Attendees, and Subfertile Women in Guangdong, China: A Cross-sectional Survey. Open Forum Infect Dis 2021; 8:ofab206. [PMID: 34235228 PMCID: PMC8253043 DOI: 10.1093/ofid/ofab206] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Accepted: 04/21/2021] [Indexed: 11/22/2022] Open
Abstract
Background Chlamydia trachomatis (CT) is a major cause of infertility
and adverse birth outcomes, but its epidemiology among childbearing-age
women remains unclear in China. This study investigated the prevalence of CT
and associated factors among Chinese women aged 16–44 years who were either
(1) pregnant, (2) attending gynecology clinics, or (3) subfertile. Methods We conducted a cross-sectional survey and recruited participants from
obstetrics, gynecology, and infertility clinics in Guangdong between March
and December 2019. We collected information on individuals’ sociodemographic
characteristics, previous medical conditions, and sexual behaviors.
First-pass urine and cervical swabs were tested using nucleic acid
amplification testing. We calculated the prevalence in each population and
subgroup by age, education, and age at first sex. Multivariable binomial
regression models were used to identify factors associated with CT. Results We recruited 881 pregnant women, 595 gynecology clinic attendees, and 254
subfertile women. The prevalence of CT was 6.7% (95% CI, 5.2%–8.5%), 8.2%
(95% CI, 6.2%–10.7%), and 5.9% (95% CI, 3.5%–9.3%) for the above 3
populations, respectively. The subgroup-specific prevalence was highest
among those who first had sex before age 25 years and older pregnant women
(>35 years). The proportion of asymptomatic CT was 84.8%, 40.0%, and
60.0% among pregnant women, gynecology clinic attendees, and subfertile
women, respectively. Age at first sex (<25 years), multipara, and ever
having more than 1 partner increased the risk of CT. Conclusions Childbearing-age women in China have a high prevalence of CT. As most women
with CT were asymptomatic, more optimal prevention strategies are urgently
needed in China.

J Med Internet Res 2021; 23:e22477. [PMID: 33890855 PMCID: PMC8105760 DOI: 10.2196/22477] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Revised: 11/05/2020] [Accepted: 03/04/2021] [Indexed: 12/15/2022] Open
Abstract
Background Men who have sex with men (MSM) face disproportionate risks concerning HIV and other sexually transmitted infections, substance use, and mental health. These outcomes constitute an interacting syndemic among MSM; interventions addressing all 3 together could have multiplicative effects. eHealth interventions can be accessed privately, and evidence from general populations suggests these can effectively address all 3 health outcomes. However, it is unclear how useable, accessible, or acceptable eHealth interventions are for MSM and what factors affect this. Objective We undertook a systematic review of eHealth interventions addressing sexual risk, substance use, and common mental illnesses among MSM and synthesized evidence from process evaluations. Methods We searched 19 databases, 3 trials registers, OpenGrey, and Google, and supplemented this by reference checks and requests to experts. Eligible reports were those that discussed eHealth interventions offering ongoing support to MSM aiming to prevent sexual risk, substance use, anxiety or depression; and assessed how intervention delivery or receipt varied with characteristics of interventions, providers, participants, or context. Reviewers screened citations on titles, abstracts, and then full text. Reviewers assessed quality of eligible studies, and extracted data on intervention, study characteristics, and process evaluation findings. The analysis used thematic synthesis. Results A total of 12 reports, addressing 10 studies of 8 interventions, were eligible for process synthesis. Most addressed sexual risk alone or with other outcomes. Studies were assessed as medium and high reliability (reflecting the trustworthiness of overall findings) but tended to lack depth and breadth in terms of the process issues explored. Intervention acceptability was enhanced by ease of use; privacy protection; use of diverse media; opportunities for self-reflection and to gain knowledge and skills; and content that was clear, interactive, tailored, reflective of MSM’s experiences, and affirming of sexual-minority identity. Technical issues and interventions that were too long detracted from acceptability. Some evidence suggested that acceptability varied by race or ethnicity and educational level; findings on variation by socioeconomic status were mixed. No studies explored how intervention delivery or receipt varied by provider characteristics. Conclusions Findings suggest that eHealth interventions targeting sexual risk, substance use, and mental health are acceptable for MSM across sociodemographic groups. We identified the factors shaping MSM’s receipt of such interventions, highlighting the importance of tailored content reflecting MSM’s experiences and of language affirming sexual-minority identities. Intervention developers can draw on these findings to increase the usability and acceptability of integrated eHealth interventions to address the syndemic of sexual risk, substance use, and mental ill health among MSM. Evaluators of these interventions can draw on our findings to plan evaluations that explore the factors shaping usability and acceptability.

Abstract
BACKGROUND Sexually transmitted diseases (STD) are caused by a variety of pathogens transmitted by sexual activity. Untreated infections can cause major complications with a substantial high cost on health sector. With the development of molecular techniques, STD screening became easier with a high sensitivity and specificity. OBJECTIVES In Lebanon, official data regarding STD trends are scarce. This study elucidates the STD molecular profile at a tertiary care center, American University of Beirut Medical Center (AUBMC), its distribution among gender and age groups, with a comparison to international studies. METHODS A retrospective data analysis was conducted on all STD panels performed at AUBMC from January 2017 till December 2019 to determine the molecular prevalence of eight different sexually transmitted organisms. RESULTS Our samples belonged to 248 females (41.5%) and 349 males (58.5%). Only 53.5% of the samples tested positive for one or more organisms. Ureaplasma urealyticum/parvum was found to be the most common pathogen (49.3%), followed by Gardenerella vaginalis (33.5%), Chlamydia trachomatis (5.36%), Mycoplasma genitalium (5.16%), Neisseria gonorrhea (2.5%), Herpes simplex virus (2.5%), and Trichomonas vaginalis (1.39%). Age was distributed between 5 and 80 years old. Regarding the pathogen's distribution among gender, Ureaplasma urealyticum/parvum, Herpes simplex virus, and Gardenerella vaginalis were more common in females, the rest was more detected in males. CONCLUSION Data will be of great importance for clinicians, in terms of diagnosis and treatment. It will help adopting an evidence based STI control programs in Lebanon, and it is essential for future larger studies and sexual health awareness programs.

Abstract
BACKGROUND The global COVID-19 pandemic has the potential to indirectly impact transmission dynamics and prevention of HIV and other sexually transmitted infections (STI). It is unknown what combined impact reductions in sexual activity and interruptions in HIV/STI services will have on HIV/STI epidemic trajectories. METHODS We adapted a model of HIV, gonorrhea, and chlamydia for a population of approximately 103 000 men who have sex with men (MSM) in the Atlanta area. Model scenarios varied the timing, overlap, and relative extent of COVID-19-related sexual distancing and service interruption within 4 service categories (HIV screening, preexposure prophylaxis, antiretroviral therapy, and STI treatment). RESULTS A 50% relative decrease in sexual partnerships and interruption of all clinical services, both lasting 18 months, would generally offset each other for HIV (total 5-year population impact for Atlanta MSM, -227 cases), but have net protective effect for STIs (-23 800 cases). If distancing lasted only 3 months but service interruption lasted 18 months, the total 5-year population impact would be an additional 890 HIV cases and 57 500 STI cases. CONCLUSIONS Immediate action to limit the impact of service interruptions is needed to address the indirect effects of the global COVID-19 pandemic on the HIV/STI epidemic.

Abstract
This secondary data analysis of a cross-sectional survey conducted in Mombasa, Kenya characterises sexual and reproductive health (SRH) indicators among adolescent girls and young women (AGYW) engaged in casual and transactional sexual relationships as well as sex work. It describes the association between awareness of local HIV programmes and SRH services uptake for AGYW engaged in sex work. Thirty-eight percent of the participants reported a history of pregnancy. Among participants not trying to get pregnant, 27% stated that they were not currently using any form of contraception. Of the participants who had an abortion, 59% were completed under unsafe conditions. For AGYW engaged in sex work, awareness of local HIV prevention programmes was associated with increased STI testing within the last year (29%) as well as at least one HIV test (99%) compared to those who were not aware of local programming (18% and 92%, respectively); however, only 26% of participants engaged in sex work had heard of local HIV prevention programmes. There were no associations between awareness of local HIV programming and rates of dual contraception use, safe abortion, most recent birth attended by a skilled health professional or testing for HIV during pregnancy. Our study found high need for SRH services, particularly, access to contraception and safe abortion. Continued efforts are required to improve access to the full spectrum of SRH interventions, including family planning services and access to safe abortion in addition to HIV prevention to promote health equity.

Abstract
(1) Background: Condomless anal sex and substance use are associated with STI risk among gay, bisexual, and other men who have sex with men (gbMSM). Our first study objective was to describe event-level sexual risk and substance use trends among gbMSM. Our second study objective was to describe substances associated with event-level sexual risk. (2) Methods: Data come from the Momentum Health Study in Vancouver, British Columbia and participants were recruited from 2012-2015, with follow-up until 2018. Stratified by self-reported HIV status, we used generalized estimating equations to assess trends of sexual event-level substance use and assessed interactions between substance use and time period on event-level higher risk sex defined as condomless anal sex with an HIV serodifferent or unknown status partner. (3) Results: Event-level higher risk anal sex increased across the study period among HIV-negative/unknown (baseline prevalence: 13% vs. study end prevalence: 29%) and HIV-positive gbMSM (baseline prevalence: 16% vs. study end prevalence: 38%). Among HIV-negative/unknown gbMSM, event-level erectile drug use increased, while alcohol use decreased over the study period. Overall, interactions between substance use and time on higher risk anal sex were not statistically significant, regardless of serostatus. However, we found a number of time-specific significant interactions for erectile drugs, poppers, Gamma-hydroxybutyrate (GHB), crystal methamphetamine and ecstasy/MDMA use among HIV-negative/unknown gbMSM. (4) Conclusion: Significant differences in substance use trends and associated risks exist and are varied among gbMSM by serostatus. These findings provide a more comprehensive understanding of the effects of event-level substance use on sexual risk through longitudinal follow-up of nearly six years.

Abstract
Incidence of sexually transmitted infections (STIs) such as chlamydia, gonorrhea, and syphilis has increased in recent years in the US and in European countries. In order to implement effective educational programs, the interests of target populations have to be identified. Since the internet is an important source of information-gathering on health issues, this study investigates web search data in large German cities related to STIs. Google Ads Keyword Planner was used to identify STI-related terms and their search volume in eleven German cities from June 2015 to May 2019. The data obtained were analyzed descriptively with regard to total search volumes, search volumes of specific thematic areas, and search volumes per 100,000 inhabitants. Overall, 741 terms with a total search volume of 5,142,560 queries were identified, with more than 70% of all search queries including a specific disease and “chlamydia” being the overall most often searched term (n = 1,196,160). Time courses of search behavior displayed a continuous interest in STIs with synchronal and national rather than regional peaks. Volumes of search queries lacked periodic patterns. Based on the findings of this study, a more open public discussion about STIs with linkage to increased media coverage and clarification of responsibilities among all STI-treating disciplines concerning management of STIs seem advisable.

Abstract
This study focused on the relationships among social support, self-esteem, and depression in transgender and cisgender individuals suffering from an incurable or curable sexually transmitted disease. Data were collected from 210 participants with an STI using a semi-structured interview along with culturally adapted standardized instruments. Results indicated no differences between transgender and cisgender groups in depression, although there were large differences in social support and self-esteem. Preliminary regression analysis identified only STI type and duration of STI as significant predictors of depression. However, when moderating roles for both social support and self-esteem were tested, each added to the explained variance and, equally importantly, revealed the effects of both gender status and social support on depression. These findings not only demonstrate how the compound stressors of gender minority status and STI type affect depressive symptoms, but also reveal the critical role that social support can play in mitigating depressive symptoms in those with gender minority status. Findings are interpreted within the context of South/Central Asian cultures that have pre- and post-colonial traditions regarding the social role of non-binary individuals.

Abstract
Sexually transmitted infections (STIs) caused by Neisseria gonorrhoeae, Chlamydia trachomatis and Mycoplasma genitalium are a common cause of pelvic inflammatory disease (PID) which can lead to tubal factor infertility (TFI). TFI is one of the most common causes of infertility, accounting for 30% of female fertility problems. STIs can also have an impact on pregnancy, leading to adverse pregnancy outcomes. Escalating antibiotic resistance in Neisseria gonorrhoeae and Mycoplasma genitalium represents a significant problem and can be therapeutically challenging. We present a comprehensive review of the current treatment options, as well as the molecular approach to this subject. We have given special attention to molecular epidemiology, molecular diagnostics, current and new treatments, and drug resistance.

Abstract
Unique compositional and functional features of the cervicovaginal microbiota have been associated with protection against and risk for sexually transmitted infections (STI). In men, our knowledge of the interaction between the penile microbiota and STI is less developed. The current state of our understanding of these microbiota and their role in select STIs is briefly reviewed, along with strategies that leverage existing findings to manipulate genital microbiota and optimize protection against STIs. Finally, we focus on major research gaps and present a framework for future studies.

Abstract
Background Patient portal modules, including electronic personal health records, health education, and prescription refill ordering, may be leveraged to address the sexually transmitted infection (STI) burden, including HIV, among gay, bisexual, and other sexual minority men (SMM). Theoretical frameworks in the implementation sciences highlight examining constructs of innovation attributes and performance expectations as key determinants of behavioral intentions and the use of new web-based health technologies. However, behavioral intentions to use patient portals for HIV and other STI prevention and care among SMM is understudied. Objective The aim of this study is to develop a brief instrument for measuring attitudes focused on using patient portals for STI prevention and care among a nationwide sample of SMM. Methods A total of 12 items of the American Men’s Internet Survey-Patient Portal Sexual Health Instrument (AMIS-PPSHI) were adapted from a previous study. Psychometric analyses of the AMIS-PPSHI items were conducted among a randomized subset of 2018 AMIS participants reporting web-based access to their health records (N=1375). Parallel analysis and inspection of eigenvalues in a principal component analysis (PCA) informed factor retention in exploratory factor analysis (EFA). After EFA, Cronbach α was used to examine the internal consistency of the scale and its subscales. Confirmatory factor analysis (CFA) was used to assess the goodness of fit of the final factor structure. We calculated the total AMIS-PPSHI scale scores for comparisons within group categories, including age, STI diagnosis history, recency of testing, serious mental illness, and anticipated health care stigma. Results The AMIS-PPSHI scale resulting from EFA consisted of 12 items and had good internal consistency (α=.84). The EFA suggested 3 subscales: sexual health engagement and awareness (α=.87), enhancing dyadic communication (α=.87), and managing sexual health care (α=.79). CFA demonstrated good fit in the 3-factor PPSHI structure: root mean square error of approximation=0.061, comparative fit index=0.964, Tucker-Lewis index=0.953, and standardized root mean square residual=0.041. The most notable differences were lower scores on the enhanced dyadic communication subscale among people living with HIV. Conclusions PPSHI is a brief instrument with strong psychometric properties that may be adapted for use in large surveys and patient questionnaires in other settings. Scores demonstrate that patient portals are favorable web-based solutions to deliver health services focused on STI prevention and care among SMM in the United States. More attention is needed to address the privacy implications of interpersonal use of patient portals outside of traditional health settings among persons with HIV.

Abstract
Women in the period of emerging adulthood (18-25 years of age) have the greatest rates of unintended pregnancy and sexually transmitted infections. Despite this disproportionate risk, women's sexual and reproductive health needs during emerging adulthood are poorly understood. As a result, few age-specific policies or person-centered practice guidelines are available to reduce sexual risk. In this commentary we explore the unique characteristics of emerging adulthood that contribute to greater sexual and reproductive health risks for women. Current evidence on sexual and reproductive health outcomes of women during emerging adulthood and limited practice guidelines are discussed. Recommendations for health care providers, especially nurses, for guiding personalized care for women in emerging adulthood are discussed.

Abstract
OBJECTIVES Portugal has the highest HIV incidence rate in Western Europe. The proportion assigned to sexual contact between men recently increased to more than 30% of all HIV infections. Men who have sex with men (MSM) are vulnerable to the acquisition of other sexually transmitted infections (STIs), increasing the per-contact risk of HIV infection. Building on syndemic theory, the aim of this analysis was to identify patterns of current sexual behaviour in MSM, and explore their relationship with self-reported current, past STI diagnoses and HIV positive serostatus. DESIGN A cross-sectional behavioural survey was conducted in Portugal among MSM, using a community-based participatory research approach. Hierarchical cluster analysis was used to identify patterns including behavioural and demographic factors. RESULTS The analysis resulted in six clusters. Three clusters showed higher rates of current STI diagnosis (ranging from 11.7% to 17.1%), past STI diagnosis (ranging from 25.5% to 41.5%) and HIV positive serostatus (ranging from 13.0% to 16.7%). From the three clusters scoring lower on current and past STI and HIV diagnoses, one was characterised by a high number of sexual partners (62% had more than 12 partners in the last year), a high proportion (94.6%) of frequent visits to gay venues to meet sexual partners and high alcohol use (46.1%). The other two clusters scored lower on high risk sexual behaviour. CONCLUSION Factors other than sexual behaviour appear to reinforce the vulnerability to STIs and HIV of some MSM in this study, suggesting a syndemic of STIs, HIV and other adverse conditions. More research is needed to better understand the drivers of the STI/HIV epidemic in Portuguese MSM, using a concept that goes beyond risk behaviour, to develop effective combination prevention interventions.

Meiksin R, Melendez-Torres GJ, Falconer J, Witzel TC, Weatherburn P, Bonell C. Theories of change for e-health interventions targeting HIV/ STIs and sexual risk, substance use and mental ill health amongst men who have sex with men: systematic review and synthesis. Syst Rev 2021; 10:21. [PMID: 33423693 PMCID: PMC7798186 DOI: 10.1186/s13643-020-01523-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Accepted: 11/08/2020] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Sexual risk, substance use, and mental ill health constitute a syndemic of co-occurring, mutually reinforcing epidemics amongst men who have sex with men (MSM). Developed since 1995, e-health interventions offer accessible, anonymous support and can be effective in addressing these outcomes, suggesting the potential value of developing e-health interventions that address these simultaneously amongst MSM. We conducted a systematic review of e-health interventions addressing one or more of these outcomes amongst MSM and in this paper describe the theories of change underpinning relevant interventions, what these offer and how they might complement each other. METHODS We identified eligible reports via expert requests, reference-checking and database and Google searches. Results were screened for reports published in 1995 or later; focused on MSM; reporting on e-health interventions providing ongoing support to prevent HIV/STIs, sexual risk behaviour, substance use, anxiety or depression; and describing intervention theories of change. Reviewers assessed report quality, extracted intervention and theory of change data, and developed a novel method of synthesis using diagrammatic representations of theories of change. RESULTS Thirty-three reports on 22 intervention theories of change were included, largely of low/medium-quality. Inductively grouping these theories according to their core constructs, we identified three distinct groupings of theorised pathways. In the largest, the 'cognitive/skills' grouping, interventions provide information and activities which are theorised to influence behaviour via motivation/intention and self-efficacy/perceived control. In the 'self-monitoring' grouping, interventions are theorised to trigger reflection, self-reward/critique and self-regulation. In the 'cognitive therapy' grouping, the theory of change is rooted in cognitive therapy techniques, aiming to reframe negative emotions to improve mental health. CONCLUSIONS The synthesised theories of change provide a framework for developing e-health interventions that might holistically address syndemic health problems amongst MSM. Improving reporting on theories of change in primary studies of e-health interventions would enable a better understanding of how they are intended to work and the evidence supporting this. The novel diagrammatic method of theory of change synthesis used here could be used for future reviews where interventions are driven by existing well-defined behaviour and behaviour change theories.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) prevention interventions for prevention interventions for women include screening, partner notification, promoting condoms, and preexposure prophylaxis (PrEP). Women's risk of acquiring HIV can help guide recommendations. METHODS We used data from Louisiana's sexually transmitted infection (STI) and HIV registries to study 13- to 59-year-old women following first diagnosis of syphilis, gonorrhea, or chlamydia during 2000-2015. We measured HIV rates reported subsequent to STI (through 2016). Rates for women without STI were estimated by subtracting women with STI from reported cases and from Census estimates for the population. PrEP cost was estimated as $11 000 per year, and effectiveness estimated as 100%. RESULTS STIs were syphilis (6574), gonorrhea (64 995), or chlamydia (140 034). These 211 603 women had 1 865 488 person-years of follow-up and 969 HIV diagnoses. Women with no STI had 5186 HIV diagnoses over 24 359 397 person-years. HIV rates diagnosis (per 100 000 person-years) were higher for women after syphilis (177.3), gonorrhea (73.2), or chlamydia (35.4) compared to women with no STI (22.4). Providing PrEP to all women diagnosed with syphilis or gonorrhea would cost $7 371 111 000 and could have prevented 546 HIV diagnoses. Limiting PrEP to 1 year after syphilis or gonorrhea diagnosis would cost $963 847 334, but only 143 HIV diagnoses were within 2 years after a syphilis or gonorrhea diagnosis. CONCLUSIONS Rates of HIV diagnosis were high after women had STI, but not high enough to make PrEP cost-effective for them. Most women diagnosed with HIV did not have previously reported STI.

Abstract
BACKGROUND Sexually transmitted infection is an infection that is typically transmitted by sexual contact and may either end or develop into a sexually transmitted disease. Today, young people are recognized as groups with special health-related vulnerabilities like drug use, unprotected sex and sexually transmitted infections. Despitea number of strategies which focused on young people's health, there was limited evidence of sexually transmitted infection among young incarcerated persons. Thus, the aim of this study was to assess the self-reported syndromes of sexually transmitted infections and associated factors among young incarcerated persons (18-29 years) in correctional facilities of the Gamo Gofa Zone, Southern Ethiopia. METHODS A facility-based cross-sectional study was conducted from March 1 to 15, 2019. Simple random sampling was used to select a total of 414 prisoners. The data were entered into Epi.info version 7 and exported and analyzed using SPSS version 20. Bivariate and multivariate logistic regression analysis were carried out. Statistical significance was declared by using the p value of <0.05 at 95% confidence interval. THE RESULTS In this study, 403 respondents participated with the response rate of 97.3%. The overall prevalence of self-reported STIs was 35 (8.7%). STI syndromes before incarceration (AOR: 5.267 (95% CI: 1.863, 14.893)), not having family support (AOR; 6.645 (95% CI: 2.327, 18.975)), history of imprisonment (AOR; 2.871 (95% CI: 1.065, 7.42)), not always using condom (AOR; 7.417, (95% CI 2.526, 21.781)), alcohol use (AOR; 5.926, (95% CI 2.282, 15.392)), chat use (AOR; 4.736, (95% CI (1.387, 16.172)) and having sex with commercial sex workers (AOR; 2.764, (95% CI 1.034, 7.388)) were significantly and independently associated with self-reported STIs. CONCLUSION Prevalence of self-reported syndromes of STI was high. Attention is needed about sexually transmitted infections for incarcerated young people by concerned bodies, including governmental and non-governmental organizations.

Abstract
Black men who have sex with men (BMSM) with a recent STI diagnosis are at particularly high risk for HIV infection and, as such, are a population for whom we must focus our antiretroviral pre-exposure prophylaxis (PrEP) implementation efforts. Understanding the factors that are associated with awareness and use of PrEP among BMSM with a recent STI diagnosis is a critical component of meeting our HIV prevention goals. For the current study, BMSM (N = 209) diagnosed with a STI in the past year residing in the Atlanta, Georgia metropolitan and surrounding areas were assessed on PrEP awareness and use, HIV risk behaviors (e.g., condomless anal intercourse) HIV risk perceptions, HIV treatment optimism, and HIV status communication self-efficacy. BMSM aware of PrEP (n = 152, 72.7%) were younger in age (OR = 0.96, 95% CI: 0.93-0.98, p = 0.030) and had significantly higher educational attainment (OR = 1.96, 95% CI: 1.28-3.02, p = 0.027) than PrEP unaware participants. In addition, participants who were aware of PrEP had significantly higher levels of HIV risk perceptions (OR = 1.27, 95% CI: 1.04-1.56, p = 0.019) than PrEP unaware participants. Finally, participants who had ever used PrEP (n = 15, 7.1%) had significantly higher HIV treatment optimism (OR = 1.55, 95% CI: 1.05-2.96, p = 0.034) than PrEP non-users. The present study showed that, while nearly three-fourths of the sample were PrEP aware, PrEP use among BMSM with STI diagnoses was limited and that PrEP is utilized less often by individuals who have less HIV treatment optimism. These findings call attention to the need to better understand how to effectively target PrEP uptake strategies for key populations.

Abstract
PURPOSE The aim of the study was to assess the epidemiological situation of newly sexually transmitted infections in Poland in 2013-2018 in comparison to other European countries based on infectious diseases surveillance. MATERIAL AND METHODS Analysis of the epidemiological situation was based on aggregated data from MZ-56 reports on infectious diseases, infections and poisoning sent from Sanitary Inspections to NIPH NIHNRI. Case-based data for gonorrhoea were analyzed in relation to transmission route and first place of medical diagnosis between 2017-2018. RESULTS Between 2013-2018 in Poland 8,436 syphilis cases were diagnosed (mean diagnosis rate was 3.66 per 100,000), 2,395 gonorrhoeae cases, whereas number of Chlamydia trachomatis infections from 2014 to 2018 were 1,179 cases. In this time the decrease of 26.2% in newly recognized gonorrhoea cases were observed, whereas the diagnosis rate for chlamydia was stable grew up: from 0.42 per 100,000 in 2014 year to 0.80 in 2018 year. Most STI cases were recognized among men: male to female ratio for syphilis was 5:1, for gonorrhoea 11:1, whereas for chlamydia there is reverse tendency, there are more cases registered among women (0.8:1). CONCLUSION There are lower STI diagnosis rates in Poland compare to European countries and there are visible big disproportion between number of cases among men and women. Distribution of cases in all voivodeships in Poland and often huge disproportion in the number of new cases between these voivodeships indicate on underreporting problem in Poland.

Abstract
OBJECTIVES Little is known about sex workers' experiences of cervical cryotherapy. We sought to understand sex workers' perspectives of 'screen and treat' programmes and their management of the World Health Organization post-treatment guidance to abstain from sex or use condoms consistently for 4 weeks. We explored contraceptive preferences and use of menstrual regulation services. METHODS We conducted semi-structured interviews with 16 sex workers and six brothel leaders in an urban brothel complex in Bangladesh between October and November 2018. All had undergone cryotherapy. We conducted a thematic analysis using deductive coding, informed by a priori themes, and inductive data-driven coding. RESULTS Most sex workers could not abstain from sex during the healing period. Consistent condom use was challenging due to economic incentives attached to condomless sex and coercive behaviours of clients. The implications of non-adherence among high-risk groups such as sex workers are not known. Use of short-acting methods of contraception was common, and discontinuation was high due to side effects and other perceived health concerns. The majority of sex workers and brothel leaders had utilized menstrual regulation services. Barriers to accessing timely menstrual regulation and other sexual and reproductive health services included limited mobility, economic costs, and discriminatory attitudes of health care workers. CONCLUSION Service innovations are required to enable sex workers to abstain or use condoms consistently in the post-cryotherapy healing phase and to address sex workers' broader sexual and reproductive health needs. Further research is required to assess the risk of HIV and other sexually transmitted infection transmission following cryotherapy among high-risk groups.

Abstract
PURPOSE The aim of the study was to assess the epidemiological situation of syphilis cases in Poland in 2019 in comparison to previous years. MATERIAL AND METHODS Analysis of the epidemiological situation was based on case-based data from reports of newly detected syphilis cases received from doctors and laboratories. Additionally aggregated data from MZ-56 reports on infectious diseases, infections and poisoning from 2013 to 2018 sent from Sanitary Inspections to NIPH NIH - NRI was used. Also, data about treatment patients in dermatology/venerology clinics in 2019 reported on MZ-14 forms and published in statistics bulletin on Ministry of Health on e-health system website (actually: https://e-zdrowie.gov.pl; https://cez.gov.pl) and NIPH NIH - NRI website were used. RESULTS In 2019 in Poland 1,511 syphilis cases were recognized (diagnosis rate was 3.96 per 100,000), including 79 cases among non-Polish citizens. The frequency of newly detected syphilis cases increased by 5% compared to the previous year and was higher by 13% compared to the median in 2013-2017 years. The syphilis cases were most often detected in the age group between 30 and 34 (20.7%) and among men (86.9%). Most cases were recognized among men who have sex with men (42%). CONCLUSION In 2019, the number of newly detected syphilis cases increased compared to the previous year. Preventive initiatives should be taken, especially among key population as young people, men who have sexual contact with men, and who have risky sexual behaviors. Low syphilis diagnosis rate compared to European countries and a huge difference in some regions in Poland for diagnosis rates indicate on problem with recognition and reporting. To improve the functioning of national surveillance is essential to adequate assessment of epidemiological situation.

Abstract
Background Previous research suggests that Tanzanian MSM might prefer consulting pharmacies and drugstores, rather than public healthcare services, when in need of STI medicines and treatment. Yet, few studies have explored the experiences of providing services to MSM clients among those working at pharmacies and drugstores and examined what challenges they encounter in providing these services. Objective To gain increased knowledge and understanding of the perceived challenges encountered by pharmacists and drugstore workers when providing STI services to MSM clients in Dar es Salaam, Tanzania. Method In early 2016, 16 semi-structured interviews were conducted with persons working at private pharmacies and drugstores in Dar es Salaam. Data were interpreted through qualitative content analysis. Results The overarching theme that emerged was labelled ‘Fighting an uphill battle’, which reflected the challenges pharmacy workers experienced during interactions with MSM clients, and in particular service provision. Pharmacy workers tried to act upon the best of their knowledge to meet the needs of clients, given their understanding of risks and obstacles that MSM faced. Yet, the lack of educational and professional preparedness and insufficient financial and human resources, regarded as necessary to meet the needs of a stigmatised client group, formed barriers for effective service delivery. Conclusions In order to support pharmacists and drug-store workers in Tanzania to address perceived challenges for service delivery to MSM clients, systematic and continuous training on MSM’s sexual health is required. Furthermore, inter-professional cooperation that harnesses provider involvement from all tiers in the healthcare system is essential to offer complementary services to ensure proper STI care and treatment. Thus, interventions that focus on inter-professional communication and interaction between pharmacists and physicians could have a positive impact on timely referrals of suspected STI cases among marginalised populations.

Abstract
Background Not all men who have sex with men (MSM) at risk for sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) infection currently receive sexual healthcare. To increase the coverage of high-quality HIV/STI care for MSM, we developed a home-care programme, as extended STI clinic care. This programme included home sampling for testing, combined with treatment and sexual health counselling. Here, we pilot implemented the programme in a hospital setting (HIV-positive MSM) to determine the factors for the successful implementation of STI home sampling strategies. Methods Healthcare providers from the HIV hospital treatment centre (Maastricht) were invited to offer free STI sampling kits (syphilis, hepatitis B, [extra]genital chlamydia and gonorrhoea laboratory testing) to their HIV-positive MSM patients (March to May 2018). To evaluate implementation of the program, quantitative and qualitative data were collected to assess adoption (HIV care providers offered sampling kits to MSM), participation (MSM accepted the sampling kits) and sampling-kit return, STI diagnoses, and implementation experiences. Results Adoption was 85.3% (110/129), participation was 58.2% (64/110), and sampling-kit return was 43.8% (28/64). Of the tested MSM, 64.3% (18/28) did not recently (< 3 months) undergo a STI test; during the programme, 17.9% (5/28) were diagnosed with an STI. Of tested MSM, 64.3% (18/28) was vaccinated against hepatitis B. MSM reported that the sampling kits were easily and conveniently used. Care providers (hospital and STI clinic) considered the programme acceptable and feasible, with some logistical challenges. All (100%) self-taken chlamydia and gonorrhoea samples were adequate for testing, and 82.1% (23/28) of MSM provided sufficient self-taken blood samples for syphilis screening. However, full syphilis diagnostic work-up required for MSM with a history of syphilis (18/28) was not possible in 44.4% (8/18) of MSM because of insufficient blood sampled. Conclusion The home sampling programme increased STI test uptake and was acceptable and feasible for MSM and their care providers. Return of sampling kits should be further improved. The home-care programme is a promising extension of regular STI care to deliver comprehensive STI care to the home setting for MSM. Yet, in an HIV-positive population, syphilis diagnosis may be challenging when using self-taken blood samples.

Abstract
There are millions of waste pickers worldwide that are predominantly located in low- and middle-income countries. They survive on sorting and selling reusable orrecyclable materials discarded by society.While sorting, they are exposed to occupational risks and hazards, including cuts from sharp objects and medical wastes, that could be contaminated by infectious diseases. Because of these exposures, a study was conducted to determine the prevalence of syphilis and other sexually transmitted infections (STI's) among waste pickers. A cross-sectional study using a semi-structured questionnaire and blood samples for serological tests were collected. A total of 1,025 waste pickers were interviewed. Most participants were women (67.54%), without a partner (70.11%), were an average of 40 years old, and had between 3 and 4 children. There were 755 samples collected for syphilis, 791 for HIV, 866 for hepatitis B, and 859 for hepatitis C. Of these samples, 28 (3.70%) waste pickers had reagent serology for syphilis, 6 (0.75%) for HIV; 6 (0.69%) for acute hepatitis B and 1 (0.11%) for hepatitis C. Overall, this study identified the serological status of waste pickers; this information can be used to encourage waste pickers to seek health treatment for STIs and receive education to understand the risks associated with being exposed to medical waste or syringes.

Abstract
Poverty and income inequality can increase a woman's decision to engage in risky transactional sex, and may lead to unimaginable harms, such as violence, substance use, and human trafficking. This study examines the facilitators and barriers to finding community and voice among women trading sex in Tijuana, Mexico, and what factors, such as socio-structural support, violence, and substance use, may impact their potential to engage with others, including human service providers. Sixty qualitative in-depth interviews were conducted with women trading sex in Tijuana, Mexico. Researchers met with participants for in-depth-face-to-face structured interviews. Data were coded using ATLAS.ti. Participants were aged 19-73 (mean: 37), 98% were of Mexican nationality, 90% reported trading sex independent of the control of others, with 58% identified as independent and street-based. Thirty percent of women trading sex reported substance use (excluding marijuana) and 20% reported injection drug use within 30 days. The majority reported no involvement in mobilization activities, but 85% expressed interest. However, barriers included stigma, cultural gender norms, partner violence, and privacy in regards to disclosure of sex trade involvement, moral conflict (revealing one's involvement in sex trade), involvement in substance use, human trafficking, and feeling powerless. Facilitators were having a safe space to meet, peer support, self-esteem, feeling heard, knowledge of rights, economic need to support families, and staying healthy. Findings imply the potential to go beyond mobilizing limited groups of women in the sex trade and instead involve whole community mobilization; that is, to reach and include the more vulnerable women (substance use, trafficked) in supportive services (social services, exit strategies, better healthcare opportunities, and/or education for healthcare providers to help break societal stigmas regarding women in the sex trade) and to change the status of women in society in general.

Abstract
BACKGROUND HPV genotypes are the most common etiological factor for genital neoplasia. It would appear that sexually transmitted infections accompanied with HPV genotypes might have synergistic interactions in cancer progression. The genetic polymorphisms are involved in metabolizing carcinogens which may contribute to the susceptibility of developing genital cancers by less efficient or overly down metabolic pathways and cell signaling. MTHFR polymorphisms are related to several metabolic disorders and human cancers. We investigated the contribution of MTHFR 1298 and MTHFR 677 polymorphisms as potential risk factors for outcomes with HPV genotypes and STIs in Iranian population. MATERIALS AND METHODS As a case-control study, MTHFR A1298C and C677T were assessed for SNPs analysis using a PCR-RFLP assay in 50 cervical intraepithelial neoplasia (CIN) cases, 98 HPV-positive subjects and 47 non-cancerous/non-HPV patients as healthy controls. RESULTS Finding suggested a significant association between the MTHFR 1298 CC polymorphisms (OR = 3.5, 95% CI = 1.13-10.82, P ≤ 0.05) in women with CIN as compared to non-cancerous/non-HPV subjects. There was not a significant difference of MTHFR 677 between outcomes. DISCUSSION It would seem MTHFR 1298 CC is more likely to be a potential risk factor for HPV-cervical cancer progression. Consequences support further attempts to understand the clinical manifestations of neoplasia related to genital infections and gene mutations.

Sun, sea and sex: a review of the sex tourism literature. TROPICAL DISEASES TRAVEL MEDICINE AND VACCINES 2020; 6:24. [PMID: 33292661 PMCID: PMC7691961 DOI: 10.1186/s40794-020-00124-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Accepted: 11/16/2020] [Indexed: 01/24/2023]
Abstract
Background Sex tourism is defined as travel planned specifically for the purpose of sex, generally to a country where prostitution is legal. While much of the literature on sex tourism relates to the commercial sex worker industry, sex tourism also finds expression in non-transactional sexual encounters. This narrative review explores current concepts related to travel and sex, with a focus on trans-national sex tourism. Methods The PubMed database was accessed to source relevant literature, using combinations of pertinent search terms. Only articles published in the English language were selected. Reference lists of published articles were also examined for relevant articles. Results With regard to preferred destinations, South/Central America and the Caribbean were more likely to receive tourists looking for casual sex. Longer duration of travel, travelling alone or with friends, alcohol or drug use, being younger and being single were factors associated with higher levels of casual sex overseas. The majority of literature retrieved on sex workers focused on risk behaviours, sexually transmitted infections (STI), mobility of sex workers and how these factors affected their lives. Sex tourists require better access to effective methods of preventing HIV, such as pre-exposure prophylaxis, and better education on HIV prevention. Drugs and alcohol play a major role as risk factors for and cofactors in casual sexual behaviour while abroad. Conclusions Travellers need to be informed of the increased risks of STI before travel. They should be aware of the local prevalence of STIs and the risks associated with their sexual practices when they travel, including engaging with commercial sex workers, having unprotected sexual intercourse and becoming victims of sexual violence.

Abstract
Despite the near-eradication of syphilis in the United States in the late 1990s, new infections have surged over the past 20 years. Dubbed, "the great imitator," syphilis infections often can be misdiagnosed and resultantly untreated. This leads to people inadvertently infecting others. This article reviews the history of syphilis, including the unethical studies undertaken in the past; current epidemiology; treatment guidelines; and strategies to reduce new infections.

Abstract
INTRODUCTION Women sex workers (WSW) are one of key population on the HIV and other sexually transmitted infections (STIs) monitoring and evaluation. Socioeconomic, structural factors and other factors associated with the workplace influence exposure to these infections. The objectives of this study were to describe and compare the social characteristics, risk behaviours and HIV, Chlamydia and gonorrhoeae prevalence according to sex work site (street or highway, clubs and flats). METHODS Cross-sectional study on 400WSW in Catalonia. Socio-demographic, sex work and behavioral characteristics were collected through personal interview. Oral fluid and urine samples were collected to determine STI prevalence. RESULTS WSW that exercised in the street or highway presented more precarious conditions and a greater vulnerability related to socioeconomic factors: older population, with a lower education level and with less economic remuneration for their service. Other factors associated with lifestyle or behaviour was also observed: greater injecting drug use, longer sex work or vulnerabilities associated with structural or social determinants: less access to health services, higher proportion of forced relations and stay in prison. The overall HIV, Chlamydia and gonorrhoeae prevalence was 3.0%, 1.8% and 0.5%, respectively, and higher in women who exercised on the street or highway: 5.6%, 1.9% and 1.2%, respectively. CONCLUSION The information generated in this study will be useful for the design specific preventive interventions aimed at this group.

Abstract
Objective To provide a review of the literature on the presence of SARS-CoV-2 in the sexual fluids of patients with COVID-19 and to observe its possible sexual transmission in a timely, rigorous, and continuously updated manner. Data sources We will conduct searches in PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), grey literature, and a centralized repository in L·OVE (Living OVerview of Evidence). L·OVE is a platform that maps PICO questions to evidence from the Epistemonikos database. In response to the COVID-19 emergency, L·OVE was adapted to expand the range of evidence it covers and customized to group all COVID-19 evidence in one place. The search will cover the period until the day before submission to a journal. Eligibility criteria for selecting studies and methods We adapted an already published standard protocol for multiple parallel systematic reviews to the specificities of this question. We will include randomized trials evaluating the sexual transmission of the SARS-CoV-2 virus. Randomized trials evaluating the sexual transmission of other coronaviruses, such as MERS-CoV and SARS-CoV, and non-randomized studies in COVID-19 will be searched if no direct evidence from randomized trials is found or if the direct evidence provides a low to a very low level of certainty for critical outcomes. Two reviewers will independently screen each study for eligibility, extract data, and assess the risk of bias. We will perform random-effects meta-analyses and use GRADE to assess the certainty of the evidence for each outcome. A living, web-based version of this review will be openly available during the COVID-19 pandemic. We will resubmit the review if the conclusions change or if there are substantial updates.

Abstract
Background Some patients who test positive for sexually transmitted infections (STIs) fail to return for results and treatment. To target improvement actions, we need to find out who these patients are. This study aimed to explore factors associated with failure to return within 30 days (FTR30) after testing among patients with positive results in a free STI testing centre in Paris. Methods All patients with at least one positive result between October 2016 and May 2017 and who completed a self-administered questionnaire were included in this cross-sectional study (n = 214). The questionnaire included sociodemographic factors, sexual behaviour and history of testing. Factors associated with FTR30 were assessed using logistic regression models. Results More than two-thirds of patients were men (72%), and the median age of patients was 27 years. Most patients were born in metropolitan France (56%) or in sub-Saharan Africa (22%). Men who had sex with men represented 36% of the study population. The FTR30 rate was 14% (95% CI [10–19%]). In multivariate analysis, previous HIV testing in younger persons (aOR: 3.36, 95% CI [1.27–8.84]), being accompanied by another person at the pretest consultation (aOR: 3.45, 95% CI [1.36–8.91]), and lower self-perceived risk of HIV infection (aOR: 2.79, 95% CI [1.07–7.30]) were associated with a higher FTR30. Testing for chlamydia/gonorrhoea without presumptive treatment was associated with a lower FTR30 (aOR: 0.21, 95% CI [0.07–0.59]). Conclusions These factors that affect failure to return are related to the patient’s representations and involvement in the STI screening process. Increasing health literacy and patient empowerment could help to decrease failure to return after being tested positive for HIV/STI. Trial registration Not applicable.

Abstract
BACKGROUND The global COVID-19 pandemic has the potential to indirectly impact the transmission dynamics and prevention of HIV and other sexually transmitted infections (STI). Studies have already documented reductions in sexual activity ("sexual distancing") and interruptions in HIV/STI services, but it is unknown what combined impact these two forces will have on HIV/STI epidemic trajectories. METHODS We adapted a network-based model of co-circulating HIV, gonorrhea, and chlamydia for a population of approximately 103,000 men who have sex with men (MSM) in the Atlanta area. Model scenarios varied the timing, overlap, and relative extent of COVID-related sexual distancing in casual and one-time partnership networks and service interruption within four service categories (HIV screening, HIV PrEP, HIV ART, and STI treatment). RESULTS A 50% relative decrease in sexual partnerships and interruption of all clinical services, both lasting 18 months, would generally offset each other for HIV (total 5-year population impact for Atlanta MSM: -227 cases), but have net protective effect for STIs (-23,800 cases). Greater relative reductions and longer durations of service interruption would increase HIV and STI incidence, while greater relative reductions and longer durations of sexual distancing would decrease incidence of both. If distancing lasted only 3 months but service interruption lasted 18 months, the total 5-year population impact would be an additional 890 HIV cases and 57,500 STI cases. CONCLUSIONS The counterbalancing impact of sexual distancing and clinical service interruption depends on the infection and the extent and durability of these COVID-related changes. If sexual behavior rebounds while service interruption persists, we project an excess of hundreds of HIV cases and thousands of STI cases just among Atlanta MSM over the next 5 years. Immediate action to limit the impact of service interruptions is needed to address the indirect effects of the global COVID pandemic on the HIV/STI epidemic.

Abstract
Trichomonas vaginalis (TV) infection is the leading cause of non-viral sexually transmitted infection (STI) globally and is endemic in rural and remote Australia. However, current accurate prevalence data for TV in urban Australia are scarce as TV is not a notifiable infection outside of the Northern Territory (NT). This study evaluated Australian guidelines for TV testing and determined TV prevalence among patients at a large urban public hospital in Melbourne, Australia. A retrospective analysis of genitourinary samples screened for STIs by multiplex polymerase chain reaction (MPCR) between May 2017 and April 2019 was performed. A total of 7155 results (5064 females) were included in the analysis. A prevalence for TV of 1.7% (n=123) was found, which was higher than Neisseria gonorrhoeae (1.4%, n=103) but less than Chlamydia trachomatis (5%, n=358). The highest rate of TV (3%) was found in females aged 30-44 years (n = 48). Routine MPCR improved TV detection almost six-fold compared with clinician request based testing. Current targeted testing guidelines for TV were inadequate for case finding in an urban setting, and clinical request among symptomatic patients was rare. MPCR testing provides a comprehensive testing strategy for curable STI, and removes the need for clinical suspicion of TV. Implementation of MPCR for STI screening can improve TV detection in populations not normally suspected to be at risk and therefore potentially reduce disease transmission or complications associated with undiagnosed infection.

Abstract
INTRODUCTION Young men who have sex with men (MSM) and transgender women (TGW) face stigmas that hinder access to healthcare. The aim of the study was to understand age-related determinants of healthcare needs and engagement among MSM and TGW. METHODS The TRUST/RV368 cohort provides integrated prevention and treatment services for HIV and other sexually transmitted infections (STIs) tailored to the needs of sexual and gender minorities. MSM and TGW aged ≥16 years in Abuja and ≥18 years Lagos, Nigeria, completed standardized behavioural questionnaires and were tested for HIV, Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) every three months for up to 18 months. Logistic regression was used to estimate adjusted odds ratios (aORs) for associations of age and other factors with outcomes of interest upon enrolment, including HIV care continuum steps - HIV testing, ART initiation and viral suppression <1000 copies/mL. Cox proportional hazards models were used to calculate adjusted hazard ratios (aHRs) for associations with incident infections. RESULTS Between March 2013 and February 2019, 2123 participants were enrolled with median age 23 (interquartile range 21 to 27) years. Of 1745 tested, 865 (49.6%) were living with HIV. HIV incidence was 11.6/100 person-years [PY], including 23.1/100PY (95% CI 15.5 to 33.1) among participants aged 16 to 19 years and 23.8/100 PY (95% CI 13.6 to 39.1) among TGW. Compared to participants aged ≥25 years, those aged 16 to 19 years had decreased odds of prior HIV testing (aOR 0.40 [95% CI 0.11 to 0.92]), disclosing same-sex sexual practices to healthcare workers (aOR 0.53 [95% CI 0.36 to 0.77]) and receiving HIV prevention information (aOR 0.60 [95% CI 0.41 to 0.87]). They had increased odds of avoiding healthcare (aOR 1.94 [95% CI 1.3 to 2.83]) and engaging in transactional sex (aOR 2.76 [95% CI 1.92 to 3.71]). Age 16 to 19 years was independently associated with increased incidence of HIV (aHR 4.09 [95% CI 2.33 to 7.49]), NG (aHR 3.91 [95% CI 1.90 to 8.11]) and CT (aHR 2.74 [95% CI 1.48 to 5.81]). CONCLUSIONS Young MSM and TGW demonstrated decreased healthcare engagement and higher incidence of HIV and other STIs as compared to older participants in this Nigerian cohort. Interventions to address unique obstacles to healthcare engagement by adolescents and young adults are needed to curb the spread of HIV and other STIs among MSM and TGW in Nigeria.

Abstract
The incidence of Chlamydia infection, in both females and males, is increasing worldwide. Male infections have been associated clinically with urethritis, epididymitis, and orchitis, believed to be caused by ascending infection, although the impact of infection on male fertility remains controversial. Using a mouse model of male chlamydial infection, we show that all the major testicular cell populations, germ cells, Sertoli cells, Leydig cells, and testicular macrophages can be productively infected. Furthermore, sperm isolated from vas deferens of infected mice also had increased levels of DNA damage as early as 4 weeks post-infection. Bilateral vasectomy, prior to infection, did not affect the chlamydial load recovered from testes at 2, 4, and 8 weeks post-infection, and Chlamydia-infected macrophages were detectable in blood and the testes as soon as 3 days post-infection. Partial depletion of macrophages with clodronate liposomes significantly reduced the testicular chlamydial burden, consistent with a hematogenous route of infection, with Chlamydia transported to the testes in infected macrophages. These data suggest that macrophages serve as Trojan horses, transporting Chlamydia from the penile urethra to the testes within 3 days of infection, bypassing the entire male reproductive tract. In the testes, infected macrophages likely transfer infection to Leydig, Sertoli, and germ cells, causing sperm DNA damage and impaired spermatogenesis.

Abstract
STI/HOP functions as a co-chaperone of HSP90 and HSP70 whose molecular function has largely been being restricted as an adaptor protein. However, its role in thermotolerance is not well explored. In this article, we have identified six members of the TaSTI family, which were named according to their distribution on group 2 and group 6 chromosomes. Interestingly, TaSTI-2 members were found to express higher as compared to TaSTI-6 members under heat stress conditions, with TaSTI-2A being one of the most heat-responsive member. Consistent with this, the heterologous expression of TaSTI-2A in Arabidopsis resulted in enhanced basal as well as acquired thermotolerance as revealed by the higher yield of the plants under stress conditions. Similarly in the case of rice, TaSTI-2A transgenics exhibited enhanced thermal tolerance. Moreover, we demonstrate that TaSTI-2A interacts with TaHSP90 not only in the nucleus but also in the ER and Golgi bodies, which has not been shown till now. Additionally, TaHSP70 was also found to interact with TaSTI-6D specifically in the cytosol. Thus, these data together suggested that the TaSTI family members might play different roles under heat stress conditions in order to fine-tune the heat stress response in plants.
