Do we Still Need Eligibility Criteria to Recommend PrEP? Impact of National Prescribing Requirements on Retention in Care and Sexually Transmitted Infections Acquisition.

Italian guidelines recommend HIV pre-exposure prophylaxis (PrEP) only upon satisfying strict eligibility criteria. The objective of this study is to evaluate if PrEP candidates attending a community-based service comply with these criteria and whether these prescribing conditions affect retention in care and sexually transmitted infections (STIs) acquisition. A retrospective analysis was performed on PrEP candidates evaluated from January 2019 to June 2022. Data were collected from self-administered questionnaires and clinical files. The population was divided in subjects with 0/1 (0/1C) and ≥ 2 (≥ 2C) criteria. Descriptive statistics and non-parametric tests were employed to describe study population. Incidence of PrEP discontinuation and of STIs was estimated per 100 persons-year of follow up (PYFU), and incidence rate ratio (IRR) was calculated. Univariate and multivariable Cox regression analyses were used to evaluate the association strength between PrEP drop out and other variables. The analyses enrolled 659 individuals: 422 individuals were included in 0/1C, 237 in ≥ 2C group, respectively. Inconsistent condom use was the most reported prescribing criteria (399 individuals, 60.6%), followed by a previous STI (186 individuals, 28.2%). 0/1C exhibited lower STIs incidence. PrEP discontinuation was 29% in 0/1C and 38% in ≥ 2C (p = 0.031). Cox model revealed that inconsistent condom use was the only prescribing criteria associated to PrEP persistence. The majority of PrEP candidate did not comply with prescribing conditions. Eligibility criteria failed to identify individuals with better retention in care. Our results suggest that Italian guidelines should be updated removing barriers to prescription.

Factors associated with Entamoeba histolytica proctocolitis in men who have sex with men: a systematic review

ObjectiveEntamoeba histolytica is parasitic infection that can cause a proctocolitis (amoebiasis) and extraintestinal sequelae (eg, liver abscess) and can be sexually transmitted in men who have sex with men (MSM)....

Development of a Machine Learning Modelling Tool for Predicting HIV Incidence Using Public Health Data from a County in the Southern United States.

Recent advancements in Machine Learning (ML) have significantly improved the accuracy of models predicting HIV incidence. These models typically utilize electronic medical records and patient registries. This study aims to broaden the application of these tools by utilizing de-identified public health datasets for notifiable sexually transmitted infections (STIs) from a southern U.S. County known for high HIV incidence rates. The goal is to assess the feasibility and accuracy of ML in predicting HIV incidence, which could potentially inform and enhance public health interventions. We analyzed two de-identified public health datasets, spanning January 2010 to December 2021, focusing on notifiable STIs. Our process involved data processing and feature extraction, including sociodemographic factors, STI cases, and social vulnerability index (SVI) metrics. Various ML algorithms were trained and evaluated for predicting HIV incidence, using metrics such as accuracy, precision, recall, and F1 score. The study included 85,224 individuals, with 2,027 (2.37%) newly diagnosed with HIV during the study period. The ML models demonstrated high performance in predicting HIV incidence among males and females. Influential predictive features for males included age at STI diagnosis, previous STI information, provider type, and SVI. For females, they included age, ethnicity, previous STIs information, overall SVI, and race. The high accuracy of our ML models in predicting HIV incidence highlights the potential of using public health datasets for public health interventions such as tailored HIV testing and prevention. While these findings are promising, further research is needed to translate these models into practical public health applications.

Anorectal Neisseria gonorrhoeae infections in women with and without reported anal sex and sex workers in sexual health centres in the Netherlands: a retrospective cohort study

Control of Neisseria gonorrhoeae infection (gonorrhoea) depends on effective testing strategies. Anorectal testing in women is often done on indication of anal sex; however, anorectal infections are seen with and without anal exposure, possibly caused by autoinoculation. This study aims to enhance understanding of anorectal infections in women, by identifying risk factors for anorectal diagnosis. In this retrospective cohort study we used national surveillance data from Dutch sexual health centres from Jan 1, 2016, to Dec 31, 2021. We included cisgender women having sex with men who were tested urogenitally and anorectally for gonorrhoea. Due to different testing policies, we identified three groups: women who had not reported recent anal sex (in the past 6 months), women who had reported recent anal sex, and sex workers. Extracted data for analyses included demographics, sexual behaviour, and diagnosis of a sexually transmitted infection (STI). Per group, multivariable models using Firth's penalised maximum likelihood logistic regression were constructed, identifying determinants of anorectal gonorrhoea among all women and among gonorrhoea-positive women only. Variables included in model construction were age, education level, migration background, number of partners, condom use, partner notification, STI symptoms, having a partner who has sex with men (MSM) or a migrant partner, previous STI test, anal sex, and chlamydia and gonorrhoea diagnoses per anatomical location. In total, 117 693 women were included: 43 757 women without reported recent anal sex, 51 728 women with reported recent anal sex, and 22 208 sex workers. In all three groups, around 2% of women were gonorrhoea positive, and 70% or more of women had an anorectal infection. The strongest determinant of anorectal gonorrhoea was a concurrent urogenital gonorrhoea diagnosis (adjusted odds ratios [aOR] 782 [95% CI 605-1018]) among women without reported recent anal sex (612 [490-768] among women with reported recent anal sex, and 464 [335-652] among sex workers). Among gonorrhoea-positive women, determinants of anorectal gonorrhoea were urogenital and anorectal chlamydia co-infection (aOR 2·03 [95% CI 1·38-3·02], for women without reported anal sex) and migration background (1·44 [1·02-2·06], for women with reported anal sex). Determinants among sex workers were condomless sex (2·43 [1·55-3·82]), anal sex (1·71 [1·10-2·66]), MSM or migrant partner (1·78 [1·13-2·79]), and urogenital and anorectal chlamydia co-infection (2·28 [1·11-5·14]). These findings support the possibility of an autoinoculation process from the urogenital to the anorectal location due to the very strong correlation between urogenital and anorectal gonorrhoea, and due to the similarity of results across all three groups. Current testing strategies could miss anorectal infections, which should be considered when developing gonorrhoea prevention and control guidelines. None.

Characteristics of Sexually Transmitted Infection (STI) Patients at the Tanggul Health Center in Jember Regency in the January-June 2023 Period

The incidence of sexually transmitted infections (STIs) can expand as the risk factors increase that increase the transmission of STIs, including having unprotected sexual contact with multiple partners, having a history of STIs, having a history of sexual violence, alcohol use, prostitution, having sexual partners who have sexual contact. additional and concomitant or have a history of previous STIs, drug use, and use of intravenous drugs. This study aimed to present the characteristics of sexually transmitted infections in Tanggul Health Center, Jember Regency, Indonesia. This study is a descriptive observational study. A total of 52 research subjects participated in this study. Analysis of variable characteristics was carried out univariately with SPSS version 25. The highest prevalence of STIs was gonorrhea, namely 20 people (38.46%), the age group with the most STIs, namely 25-49 years, as many as 36 people (69.23%), sex of STI sufferers the most were men, 37 people (71.15%) and the risk factors for experiencing STIs that were most common were customers of sex workers, 31 people (59.61%).

Unravelling Delay in Care for Sexually Transmitted Infections-Related Symptoms in a Developing Country Setting (Jamaica).

Sexually transmitted infections (STIs) and STI treatment remain a challenge in public health. There is little understanding of related factors influencing health seeking behaviour and delay of care among clinic attendees in Jamaica. To determine socio-demographic profile of clinic attendees with STI and identify factors associated with delay in seeking care for STI-related symptoms. A cross-sectional study was done. 201 adult patients presenting with STI symptoms from four health centres in Kingston and St Andrew were selected. A 24-item interviewer-assisted questionnaire was used to obtain data on socio-demographic characteristics, patients' symptoms and duration, previous STIs, knowledge of complications and seriousness of STIs, and factors influencing decision to seek medical care. Almost 75% delayed seeking care for STIs. Recurrent STIs was identified in 41% of patients. 'Could not find time' was the most commonly reported reason for delay in seeking care (36%). Females were 3.4 times more likely to delay seeking care for STI symptoms than males (OR 3.42, 95% CI: 1.73-6.73). Those with primary level education and below were 5 times more likely to delay seeking care for STI symptoms than those with at least secondary level education (OR 5.05, 95% CI: 1.09-23.46). Participants viewed staff as confidential (68%) and 65% thought health-care workers spent adequate time during consultations. Lower education level and the female gender are associated with delay in seeking care for STI-related symptoms. These factors should be considered when developing interventions to reduce delay in care for STI-related symptoms.

Previous Sexually Transmitted Infections and Partner Services Interviews as Predictors of Subsequent Interview Completion Among Cisgender MSM: Partner Services Fatigue?

Anecdotal reports suggest that partner services (PS) are less successful among people with repeat sexually transmitted infection (STI) diagnoses and/or previous PS interactions. We examine whether having repeated STI diagnoses and/or PS interactions is associated with PS outcomes among men who have sex with men (MSM). With STI surveillance and PS data for MSM diagnosed with gonorrhea, chlamydia, and/or syphilis from 2007 to 2018, in King County, WA, we used Poisson regression models to examine the relationships between PS outcomes (e.g., completing a PS interview and providing identifying information for a contact) with (1) number of previous STI case episodes and (2) number of previous PS interviews completed. Of the 18,501 MSM STI case patients initiated for interview in the analytic period (2011-2018), 13,232 (72%) completed a PS interview, and 8,030 (43%) had at least 1 prior PS interview. The proportion of initiated cases successfully interviewed declined from 71% among those with no previous PS interview to 66% among those with ≥3 prior interviews. Similarly, the proportion of interviews with ≥1 partner identified declined with greater numbers of previous PS interviews (from 46% [0 interviews] to 35% [≥3 interviews]). In multivariate models, having ≥1 prior PS interview was negatively associated with completing a subsequent interview and providing partner locating information. Having a history of STI PS interviews is associated with less PS engagement among MSM. New approaches to PS should be explored to address the growing epidemic of STIs among MSM.

Sexually Transmitted Infections Prevalence and Cascade of Care among Undocumented Sex Workers: A Twenty-Year-Long Experience

Undocumented migrant sex-workers (SW) are vulnerable to Sexually Transmitted Infections (STIs). However, data regarding prevalence and linkage-to-care are lacking. Defining epidemiology is crucial to implement preventive measures. We report data from SW attending a facility for migrants in Piacenza, Italy. We collected medical records from 1999 until 2021. Quantitative variables were summarized as mean and standard deviation (SD), and qualitative ones by absolute and relative frequencies. Logistic regression analysis was performed to assess the relationship between sociodemographic, clinical variables, positive testing, and loss to follow-up (LFU). Overall, 1035 STI episodes were collected, 917 in cisgender-females (CF), and 118 in transgender-females (TF). Overall, 474 diagnoses were made. Three-hundred-ninety-two/474 (82.7%) started therapy, and 264/474 (55.7%) complied with a follow-up. Only 51.5% of HBV and 30.8% of HIV were linked to care. Having symptoms (OR 1.70 (95% CI 1.06-2.73), p = 0.028) and previous STIs (OR 1.36 (95% CI 1.04-1.77), p = 0.022) were associated with a higher chance of STIs, while at-risk intercourse to lower risk (OR 0.19 (95% CI 0.07-0.49), p = 0.001). TF had higher odds of bloodborne infections and syphilis (OR 2.61 (95% CI 1.17-5.80), p = 0.019). Regarding follow-up, the older the patient, the higher the LFU (OR 1.05 (95% CI 1.01-1.10), p = 0.021). Our data showed a high prevalence of STIs and LFU among undocumented SW. TF are even more vulnerable. Further efforts should be put into targeted interventions.

Herpes, Syphilis, and Human Immunodeficiency Virus Coinfection Among Transgender Women in Central Brazil.

Background Human herpesvirus 2 (HSV-2) is a major cause of sexually transmitted infections (STIs) worldwide and often occurs synergistically with syphilis, and human immunodeficiency virus (HIV) infection. Transgender women (TGW) are disproportionately affected by STIs. The aim of this study was to estimate the prevalence of HSV-2 monoinfection, and HSV-2, syphilis, and HIV coinfection (triple infection) among TGW in Central Brazil. Methods A seroprevalence survey was conducted among TGW in Central Brazil from 2018 to 2019. Participants were recruited using respondent-driven sampling and interviewed about their sociodemographic characteristics and STI risk behaviors, and were tested for antibodies to HSV-2, Treponema pallidum, and HIV. Multivariable logistic regression models were used to identify variables associated with HSV-2 monoinfection and triple infection. Results Of the 431 participants, 345 (80%) were positive for HSV-2 antibodies, of whom 36 were HSV-2 immunoglobulin M–positive, and 340 were HSV-2 immunoglobulin G–positive. Human herpesvirus 2 and HIV coinfection, HIV and syphilis coinfection, and triple infection were detected in 38 participants (9.0%), 58 participants (13.8%), and 27 participants (6.4%), respectively. Report of a previous STI was associated with a decreased risk of HSV-2 monoinfection (adjusted odds ratio, 0.39), and an increased risk of triple infection (adjusted odds ratio, 4.4). Participants who reported sex not only with men had a 2.42-fold increased risk of triple infection. Conclusions The high prevalence of HSV-2, syphilis, and HIV coinfection among TGW is a cause for concern. Transgender women should be screened for HIV and other STIs. Further studies of risk factors for triple infection among TGW are warranted.

Geosocial Networking App Use Associated With Sexual Risk Behavior and Pre-exposure Prophylaxis Use Among Gay, Bisexual, and Other Men Who Have Sex With Men: Cross-sectional Web-Based Survey.

BackgroundIn the United States, geosocial networking (GSN) apps (ie, mobile dating apps) have become central to dating and sexual interactions in recent years. Among gay, bisexual, and other men who have sex with men (GBM), these apps play an important role in reducing barriers and facilitating partner seeking. However, despite these benefits, there are concerns that these apps may facilitate risky sexual behavior and transmission of sexually transmitted infections (STIs) among GBM.ObjectiveThis study aimed to examine the association between GSN app use and sexual risk in a US sample of GBM.MethodsUsing a cross-sectional design, respondents (N=223) completed a web-based survey assessing their use of GSN apps, sexual risk and protective behaviors, HIV serostatus, and previous STI diagnoses.ResultsRespondents were aged 21-78 (mean 31.90, SD 10.06) years and 69.5% (155/223) were non-Hispanic White. The sample included respondents from 40 states and the District of Columbia. Nearly half (104/223, 47%) of the participants reported using GSN apps. GSN users were more likely to report past-year condomless anal intercourse (P<.001), 3 or more sexual partners in the previous year (P<.001), and a previous STI diagnosis (P=.001) than nonusers. GSN users also reported more frequent use of recreational drugs before sex (P=.001), alcohol use before sex (P<.001), and cannabis use before sex (P=.01). Interestingly, GSN users were also more likely to report having ever taken an HIV test (P<.001) and using pre-exposure prophylaxis (P=.03). The rates of HIV seropositivity did not differ significantly between GSN users and nonusers (P=.53). Among the subset of GSN users, 38 participants reported using only GBM-specific GSN apps (eg, Grindr), whereas 27 participants reported using only sexuality nonspecific GSN apps (eg, Tinder). Exclusive users of GBM–specific apps reported more frequent recreational drug use before sex (P=.01) and were also more likely to report past-year condomless anal intercourse (P<.001), 3 or more sexual partners in the previous year (P=.004), a previous STI diagnosis (P=.002), and HIV testing (P=.003). Alcohol use before sex, cannabis use before sex, pre-exposure prophylaxis use, and HIV rates were similar between both groups (P>.11).ConclusionsThe findings suggest that GSN apps may be a useful pathway for interventions aimed at reducing STI risk in GBM. Future prospective studies should examine how risk levels change after the initiation of GSN app use.

Novel Use of Video Logs to Deliver Educational Interventions to Black Women for Disease Prevention.

IntroductionCisgender Black women comprise 67% of new human immunodeficiency virus (HIV) diagnoses among women in the South and are 11 times more likely to become HIV positive than White women in Texas. Optimal progress toward ending the HIV epidemic requires strategies that will interrupt transmission pathways in hotspot locations like Harris County, TX. Researchers are calling for public health interventions that can prevent HIV and sexually transmitted infections (STI) transmission; thus, we launched the first video log (vlog)-based, pilot HIV prevention intervention.MethodsIn a prospective. randomized controlled trial of two educational intervention strategies delivered as vlogs eligible participants were randomized to either 1) an interactive gaming, education-based strategy, or 2) a storytelling, education-based strategy. Eligible participants were cisgender Black women being seen in the emergency department (ED) for a non-emergent condition who reported recent condomless heterosexual sex, were ages 18–45, and had social media access. Enrolled women completed a screening assessment, informed consent, randomization, and 10-item pre-and-post assessments with true/false statements before and after viewing a brief vlog on a tablet device to identify changes in knowledge before and after being educated on HIV/STI transmission.ResultsTwenty-six women were randomized to the Taboo group, an interactive gaming, education-based strategy, (14 [53.8%]), or to storytelling, an education-based strategy using non-fictional and fictional case scenarios (12 [46.2%]). Taboo participants self-identified as African-American (12 [85.7%]), Black (1 [7.1%]) or “other” (1 [7.1%]), were younger (28.6% were ≥ 30 years), single (57.1%), reported a previous STI (8 [57.1%]), and were likely employed (57.2%). Storytelling participants self-identified as African-American (7 [58.3%]) or Black (5 [41.7%]), were older (49.9% were ≥ 30 years), in a relationship but not married (50%), and half were unemployed. Highest level of education and monthly income varied. The storytelling strategy increased knowledge in two areas and the Taboo strategy increased knowledge in one. No intervention effect was identified in three areas, and a significant decrease in knowledge (P < .0001) was discerned in eight areas for Taboo and six areas for storytelling.ConclusionFurther research is necessary to confirm whether delivery of HIV prevention interventions with vlogs is a useful approach for HIV-vulnerable populations. Findings suggest that vlogs are a feasible approach to brief behavioral interventions during an ED visit.

Phylogeny-based identification of Mycoplasma genitalium in a Nigerian population of apparently healthy sexually active female students.

IntroductionMycoplasma genitalium is an emerging sexually transmitted pathogen. Sexually transmitted infection (STI) is still a burden for Nigerian women because it is asymptomatic. The lack of detection of M. genitalium in apparently healthy sexually active females in Nigeria is due to non-application of high throughput molecular approach. We conducted a study to identify M. genitalium in apparently healthy Nigerian female students using a phylogenetic approach.Methodsone hundred endocervical swab specimens were collected from a student population of sexually active females aged 15 - 39 years. The 16SrRNA gene V1-V3 region of M. genitalium were amplified directly from the specimens before sequencing. Maximum Likelihood (ML) phylogenetic analysis was carried out to determine genetic relatedness.Resultsthe prevalence of M. genitalium infection was 1% among students. The majority (59%) of them were between 20 - 24 years, with a mean age of 26.2 ± 2.66 years. High number of sexual partners, previous STI and irregular condom use were significantly associated (P < 0.05) with the prevalence of M. genitalium infection. There was extensive lack of knowledge (0%) about M. genitalium infection among the students. Phylogenetic analysis revealed three clades with different relatedness. Our study highlighted that 16SrRNA gene was a detector of M. genitalium, but it shared no phylogenetic relationship with other examined species from around the world.Conclusiondespite a low prevalence of M. genitalium infection among the understudied group, its cause was not established; consequently, prevention and control measures should be based on health education in the general population in order to limit the spread of this pathogen. To our knowledge, this is the first study to identify M. genitalium among the general population of Nigeria using a phylogenetic approach.

A Survey on Knowledge, Prevention, and Occurrence of Sexually Transmitted Infections among Freshmen from Four Italian Universities.

Background. The peak of sexually transmitted infections (STI) among adolescents/young adults suggests a low level of prevention. In order to assess whether the level of sexual health education (SHE), received by several channels, was effective at improving sexual behaviors, we conducted a survey among freshmen from four Italian universities. Methods. This observational cross-sectional study was carried out with an anonymous self-reported paper questionnaire, administered during teaching lectures to university freshmen of the northern (Padua, Bergamo, and Milan campuses) and southern (Palermo campus) parts of the country. Knowledge of STI (a linear numerical score), knowledge of STI prevention (dichotomous variable: yes vs. no) and previous STI occurrence (polytomous variable: “no”; “don’t know”; “yes”) were the outcomes in the statistical analysis. Results. The final number of freshmen surveyed was 4552 (97.9% response rate). The mean age of respondents was 21.4 ± 2.2 years and most of them (70.3%) were females. A total of 60% of students were in a stable romantic relationship. Only 28% respondents knew the most effective methods to prevent STI (i.e., condom and sexual abstinence), with a slightly higher prevalence of correct answers among females (31.3%) than males (25.8%). Students with history of STIs were 5.1%; they reported referring mostly to their general practitioner (GP) (38.1%) rather than discussing the problem with their partner (13.1%). At multivariable analysis, a significantly higher level of STI knowledge was observed in older students (25+ years of age), biomedical students, and those from a non-nuclear family; lower levels were found among students of the University of Palermo, and those who completed a vocational secondary school education. Those who had less knowledge about the most effective tools to prevent STIs included males, students from the University of Palermo, students registered with educational sciences, economics/political sciences, those of foreign nationality, and those whose fathers had lower educational levels. The risk of contracting a STI was significantly lower only in students not in a stable relationship (relative risk ratio, RRR = 0.67; 95% confidence interval, 95%CI = 0.48; 0.94), whereas such risk was significantly higher in students with higher STI knowledge (RRR = 1.15; 95%CI = 1.08; 1.22). Discussion and Conclusions. University freshmen investigated in this study had poor knowledge of STIs and their prevention. Unexpectedly, those with higher levels of knowledge had an increased risk of STIs. There have been no educational interventions—with good quality and long-term follow-ups—that increased the confidence that such SHE programs could have population level effects. A new high-quality study is therefore recommended to assess the effectiveness of an intervention generating behavioral changes; increasing only STI knowledge may not be sufficient.

1356. Association Between Marital Status and Pre-pregnancy STI Counseling Among Women Who Have Recently Given Birth: RI PRAMS 2016-2018

Abstract Background As rates of sexually transmitted infections (STIs) continue to rise, all women of reproductive age can suffer from complications particularly during pregnancy which can lead to adverse neonatal outcomes. Currently, data on STI counseling among married women are limited. This study aims to assess differences in pre-pregnancy STI counseling based on marital status among women who have recently given birth. Methods We utilized the Rhode Island Pregnancy Risk Assessment Monitoring System (RI PRAMS) 2016-2018, a population-based survey of postpartum women. Mothers self-reported if they have received STI counseling for chlamydia, gonorrhea, and syphilis during any health care visit in the 12 months before becoming pregnant. Marital status was obtained from the birth certificate. Multivariable logistic regression analysis was performed adjusting for age, race, Hispanic ethnicity, education, insurance, income, and previous live birth. We accounted for weighting and complex survey design. Results Our analytic sample included 2,361 mothers. More than half of the women reported never having received pre-pregnancy STI counseling about the 3 most reported and curable STIs in the US. Among them, an estimated 78.9% (n=1,207) of married women did not receive pre-pregnancy STI counseling compared to 53.6% (n=429) of unmarried women (Table 1). Married women had 0.61 (95% CI: 0.46, 0.81) odds of receiving STI counseling before pregnancy compared to unmarried women (Figure 1). Other risk factors for not receiving STI counseling included having a college education or higher or having a previous live birth. Table 1. Characteristics of Women who have Recently Given Birth by Marital Status, RI PRAMS 2016-2018 (n=2,361) *Unknown/missing values for each category &amp;lt;10%.**Uninsured population &amp;lt;1% Figure 1: Adjusted Odds of Having Received Pre-pregnancy STI Counseling among Recent Mothers, RI PRAMS 2016-2018 (n=2,361) *P-value &amp;lt;0.05Reference Group; Marital Status: unmarried, Age: &amp;lt; 25 years old, Race: White, Hispanic: Non-Hispanic, Education: High school degree or less, Insurance: Public insurance, Income: &amp;lt; &amp;24,000, Previous live birth: No previous live birth Conclusion Selective STI counseling creates gaps and missed opportunities to address STIs early before pregnancy. All women regardless of their perceived risk for STI or assumptions based on their marital status should receive proper STI counseling as all women are vulnerable and at higher risk of developing complications. Health care providers should increase efforts to address this gap and counsel all women about STIs during every visit irrespective of their marital status.

HIV and STI prevalence and testing history among men who have sex with men in Hanoi, Vietnam.

HIV and other sexually transmitted infections (STIs) have disproportionately affected communities of men who have sex with men (MSM). We describe HIV and STI prevalence and testing patterns among urban Vietnamese MSM. We conducted a cross-sectional community-based study of MSM in Hanoi, Vietnam in 2016. Participants self-reported experiences of social stigma in healthcare settings and previous HIV and STI testing. STI testing included HIV, herpes simplex virus-2 (HSV-2), syphilis, gonorrhea, and chlamydia. 205 MSM participated in the study. STI prevalence was HIV (10%), HSV-2 (4%), syphilis (13%), gonorrhea (34%), and chlamydia (19%). More than half (55%) of participants tested positive for at least one STI. Most participants had been previously tested for HIV or another STI (72%), with 24% previously receiving a positive result. Perceived and enacted social stigma in healthcare contexts was negatively associated with previous HIV or STI testing (adjusted prevalence odds ratio (aPOR): 0.22; 95% confidence interval (CI): 0.10-0.48). High prevalence of STIs was observed among Vietnamese MSM, and perceived and enacted stigma was related to HIV and STI testing. Our findings reaffirm the importance of regular STI screening among this population as well as additional outreach to promote safe HIV and STI healthcare engagement.

Prevalence and associated predictors of HIV and syphilis among women, south of Brazil

To investigate the general prevalence of sexually transmitted infections (STIs) and the factors associated with syphilis and HIV in women treated in the Integrated Health System (SINAS). Cross-sectional database study with 6.993 patients treated at a referral center in the state of Paraná, Brazil, from January 2013 to December 2015. The overall prevalence was 2.39% for syphilis and HIV, being 0.65 and 0.22% for pregnant women and 3.07 and 0.78% for non-pregnant women, respectively. After adjusting the variables in the logistic regression model, the main predictors associated with syphilis were the age groups 41 to 59 and 60 to 83 years old (p &lt;0.001), non-pregnant women (p &lt;0.01), marital status married (p &lt;0.001), drug use (p &lt;0.01) and previous STIs (&lt;0.001). For HIV, the predictors were city of residence (&lt;0.001), reason for search (p &lt;0.01), reported previous STTs (p &lt;0.001). The population served had a higher prevalence of syphilis when compared to the international panorama, while the HIV values were lower. The predictors associated with STIs were non-pregnant, heterosexual women, aged between the second and fourth decade of life, higher education and who did not use condoms regularly. This study presents relevant information for the evaluation and development of measures that prevent, control and are related to the diagnosis and treatment of the investigated STIs.

Effect of Previous Adverse Reproductive Health Outcomes on Young Women's Engagement in a Health Coaching Intervention to Improve Contraceptive Continuation.

Nonadherence in sexual risk reduction interventions might be common among adolescents. We compared intervention completion rates among adolescent and young adult women with and without a previous pregnancy or sexually transmitted infection (STI) participating in a program to improve contraceptive continuation. Secondary data analysis from a feasibility study of a health-coaching intervention to improve contraceptive continuation. Three urban pediatric clinics in Philadelphia. Women ages 14-22 years who were English-speaking, sexually active in the past year, not desiring pregnancy in the next year, and starting a new contraceptive method. At baseline, participants completed a sociodemographic questionnaire and semistructured interview, followed by 5 monthly coaching sessions. Interviews and coaching sessions were audio-recorded, transcribed, and coded for thematic content. Intervention completion was defined as the number of completed coaching sessions. Secondary outcomes were qualitatively explored group differences in reproductive knowledge, attitudes, and risk perception. Participants with a previous adverse outcome (a previous STI and/or a previous pregnancy) completed fewer coaching sessions than those without such history (median: 2 vs 4; P = .03). Both groups had low HIV/STI knowledge, negative attitudes toward pregnancy, and low HIV/STI risk perception. Those with a previous adverse reproductive outcome held more negative attitudes toward condoms. Despite similar reproductive knowledge, attitudes, and risk perception, young women who have experienced an adverse reproductive outcome might be less likely to fully engage in sexual risk reduction interventions. Future studies should confirm these findings and consider strategies to optimize the intervention's reach for vulnerable youth.

The impact of the COVID-19 pandemic on Sexually Transmitted Infections surveillance data: incidence drop or artefact?

BackgroundBefore the COVID-19 pandemic, Sexually transmitted infections (STIs) were increasing in Europe, and Spain and Catalonia were not an exception. Catalonia has been one of the regions with the highest number of COVID-19 confirmed cases in Spain. The objective of this study was to estimate the magnitude of the decline, due to the COVID-19 pandemic, in the number of STI confirmed cases in Catalonia during the lockdown and de-escalation phases.MethodsInterrupted time series analysis was performed to estimate the magnitude of decline in the number of STI reported confirmed cases - chlamydia, gonorrhoea, syphilis, and lymphogranuloma venereum- in Catalonia since lockdown with historical data, from March 13th to August 1st 2020, comparing the observed with the expected values.ResultsWe found that since the start of COVID-19 pandemic the number of STI reported cases was 51% less than expected, reaching an average of 56% during lockdown (50% and 45% during de-escalation and new normality) with a maximum decrease of 72% for chlamydia and minimum of 22% for syphilis. Our results indicate that fewer STIs were reported in females, people living in more deprived areas, people with no previous STI episodes during the last three years, and in the HIV negative.ConclusionsThe STI notification sharp decline was maintained almost five months after lockdown started, well into the new normality. This fact can hardly be explained without significant underdiagnosis and underreporting. There is an urgent need to strengthen STI/HIV diagnostic programs and services, as well as surveillance, as the pandemic could be concealing the real size of the already described re-emergence of STIs in most of the European countries.

Sexually transmitted infections and factors associated with risky sexual practices among female sex workers: A cross sectional study in a large Andean city

There are limited published data on factors related to risky sexual practices (RSP) affecting sexually transmitted infections (STIs) among female sex workers (FSWs) in Ecuador. Cross-sectional study of FSWs presenting for a consultation in a primary health care centre during 2017. A questionnaire was administered to collect information on RSP and potential risk factors including age, membership of an FSW association, self-report of previous STI diagnosis, previous treatment for suspected STI and temporary migration for sex work. Associations between RSP and potential risk factors were estimated by logistic regression. The proportion of STI was estimated from vaginal swabs by real-time PCR for four sexually transmitted pathogens (Neisseria gonorrhoeae, Trichomonas vaginalis, Chlamydia trachomatis, and Mycoplasma genitalium). Of 249 FSWs recruited, 22.5% had reported RSPs at least once during sex work. Among FSWs reporting unprotected vaginal sex in the previous three months, 25.5% had at least one other RSP type. 17.6% (95%CI 13.3-22.8) had at least one active STI. Prevalence of co-infections was 2.4% (95%CI 1.1-5.2). In multivariable analysis, RSP was associated with age (adjusted OR 1.06; 95%CI 1.02-1.10), membership of an FSWs association (aOR 3.51; 95%CI 1.60-7.72) and self-reported previous STI (aOR 3.43; 95%CI 1.28-9.17). Among a population of female sex workers with high proportion of STIs, increasing age and belonging to an FSWs association was associated with a higher likelihood of engaging in RSP with clients. Engaging with FSWs organisations may reduce the burden of STI among sex workers.

Prevalence and Risk Factors of Chlamydia Trachomatis Infection Among Women Consulting at the Sexually Transmitted Infection Centre in la Reunion: A Cross-Sectional Study

RésuméIntroductionL'infection à Chlamydia trachomatis (CT) est l'infection sexuellement transmissible (IST) bactérienne la plus répandue dans le monde. Souvent asymptomatique, elle peut mener à des complications significatives chez les femmes. L'objectif de cette étude était de déterminer la prévalence du CT en centre de dépistage à la Réunion et d'explorer les déterminants de cette infection.MéthodeEnquête transversale comprenant un questionnaire anonyme et une PCR par auto-écouvillon génital mené chez les femmes consultant dans deux centres de dépistage à la Réunion au cours d'une année.RésultatsParmi les 620 femmes testées, la prévalence du CT était de 6,6% (IC 95% [4, 7, 8, 6]). La prévalence maximale par classe d'âge se situait entre 12 et 17 ans avec une prévalence de 14,3% contre 7,5% chez les 18-24 ans et 3,9% chez les 25-67 ans (p = 0,003). Les facteurs de risques étaient le jeune âge (p = 0,02), un premier rapport sexuel entre 11 et 14 ans (p = 0,01), une absence d'antécédent de dépistage (p = 0,02) et les motifs de consultation « infidélité du partenaire » (p = 0,01) et « partenaire infecté » (p = 0,02).ConclusionLa prévalence du CT chez les mineures réunionnaises est élevée. Un dépistage plus systématique et un renforcement de la sensibilisation aux IST chez elles semblent primordiaux.
