Abstract
BACKGROUND Standard-of-care nucleic acid amplification tests (routine NAATs) for Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) can take several days to result and therefore delay treatment. Rapid point-of-care GC/CT NAAT (rapid NAAT) could reduce the time to treatment and therefore onward transmission. This study evaluated the incremental cost per infectious day averted and overall cost of implementation associated with rapid compared with routine NAAT. METHODS Prospective sexually transmitted infection (STI) treatment data from men who have sex with men and transgender women in San Diego who received rapid NAAT between November 2018 and February 2021 were evaluated. Historical time from testing to treatment for routine NAAT was abstracted from the literature. Costs per test for rapid and routine NAAT were calculated using a micro-costing approach. The incremental cost per infectious day averted comparing rapid to routine NAAT and the costs of rapid GC/CT NAAT implementation in San Diego Public Health STI clinics were calculated. RESULTS Overall, 2333 individuals underwent rapid NAAT with a median time from sample collection to treatment of 2 days compared with 7 to 14 days for routine NAAT equating to a reduction of 5 to 12 days. The cost of rapid and routine GC/CT NAAT was $57.86 and $18.38 per test, respectively, with a cost-effectiveness of between $2.43 and $5.82 per infectious day averted. The incremental cost of rapid NAAT improved when at least 2000 tests were performed annually. CONCLUSIONS Although rapid GC/CT NAAT is more expensive than routine testing, the reduction of infectious days between testing and treatment may reduce transmission and provide improved STI treatment services to patients.

Abstract
Pre-exposure prophylaxis (PrEP) is an effective tool for human immunodeficiency virus (HIV) prevention. The purpose of this study is to identify correlates of PrEP retention using patient data from an urban, publicly funded safety-net clinic in Washington, DC. Cox proportional hazards regression, logistical regression, and survival curves were used to assess the association of age, gender, race/ethnicity, insurance, number of partners, and sexually transmitted infection (STI) diagnosis at PrEP initiation with time on PrEP. From August 2016-December 2020, 1,126 people were prescribed PrEP - patients were mostly Black (44.8%) or Latinx (30.4%) and identified as cisgender men (84.6%). Half had no insurance (49.1%), with the remaining patients reporting private (28.9%) or public (21.5%) insurance. Age at PrEP prescription ranged from 15 to 66 with 80% being 20 to 39 years. For the 87.7% (n = 987) of patients who discontinued PrEP, mean PrEP time was 158 days and median was 28 days. The highest rates of discontinuation were observed within the first month with 44.3% discontinuing by day 30, 52.3% by 3 months, and 73.2% by 1 year. Cisgender women, transgender persons, and those younger than 30 years were more likely to discontinue PrEP. Latinx and patients with less than 3 male partners in the last 90 days were less likely to discontinue PrEP. We demonstrated a high level of PrEP uptake among populations disproportionally affected by HIV. Future analyses are needed to examine ways of reducing barriers to PrEP initiation and improving PrEP adherence.

Clinical Decision Support System for Guidelines-Based Treatment of Gonococcal Infections, Screening for HIV, and Prescription of Pre-Exposure Prophylaxis: Design and Implementation Study. JMIR Form Res 2024; 8:e53000. [PMID: 38621237 PMCID: PMC11058559 DOI: 10.2196/53000] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 02/02/2024] [Accepted: 02/21/2024] [Indexed: 04/17/2024] Open
Abstract
BACKGROUND The syndemic nature of gonococcal infections and HIV provides an opportunity to develop a synergistic intervention tool that could address the need for adequate treatment for gonorrhea, screen for HIV infections, and offer pre-exposure prophylaxis (PrEP) for persons who meet the criteria. By leveraging information available on electronic health records, a clinical decision support (CDS) system tool could fulfill this need and improve adherence to Centers for Disease Control and Prevention (CDC) treatment and screening guidelines for gonorrhea, HIV, and PrEP. OBJECTIVE The goal of this study was to translate portions of CDC treatment guidelines for gonorrhea and relevant portions of HIV screening and prescribing PrEP that stem from a diagnosis of gonorrhea as an electronic health record-based CDS intervention. We also assessed whether this CDS solution worked in real-world clinic. METHODS We developed 4 tools for this CDS intervention: a form for capturing sexual history information (SmartForm), rule-based alerts (best practice advisory), an enhanced sexually transmitted infection (STI) order set (SmartSet), and a documentation template (SmartText). A mixed methods pre-post design was used to measure the feasibility, use, and usability of the CDS solution. The study period was 12 weeks with a baseline patient sample of 12 weeks immediately prior to the intervention period for comparison. While the entire clinic had access to the CDS solution, we focused on a subset of clinicians who frequently engage in the screening and treatment of STIs within the clinical site under the name "X-Clinic." We measured the use of the CDS solution within the population of patients who had either a confirmed gonococcal infection or an STI-related chief complaint. We conducted 4 midpoint surveys and 3 key informant interviews to quantify perception and impact of the CDS solution and solicit suggestions for potential future enhancements. The findings from qualitative data were determined using a combination of explorative and comparative analysis. Statistical analysis was conducted to compare the differences between patient populations in the baseline and intervention periods. RESULTS Within the X-Clinic, the CDS alerted clinicians (as a best practice advisory) in one-tenth (348/3451, 10.08%) of clinical encounters. These 348 encounters represented 300 patients; SmartForms were opened for half of these patients (157/300, 52.33%) and was completed for most for them (147/300, 89.81%). STI test orders (SmartSet) were initiated by clinical providers in half of those patients (162/300, 54%). HIV screening was performed during about half of those patient encounters (191/348, 54.89%). CONCLUSIONS We successfully built and implemented multiple CDC treatment and screening guidelines into a single cohesive CDS solution. The CDS solution was integrated into the clinical workflow and had a high rate of use.

Abstract
Sexually transmitted infections (STIs) are commonly encountered in primary care. The Centers for Disease Control and Prevention and the US Preventive Services Task Force have both issued guidelines about screening for chlamydia, gonorrhea, syphilis, and HIV. By eliciting a sexual history, understanding their patients' anatomy, and considering factors which may increase the likelihood of STIs and their sequelae, clinicians can implement a practical, evidence-based approach to STI screening.

Abstract
INTRODUCTION Men who have sex with men (MSM) account for over half of new diagnoses of human immunodeficiency virus (HIV) every year in the United States, with over one-third of this population being unaware of their HIV status. The U.S. Military requires biannual HIV testing for all service members. Although this may be an appropriate recommendation for the military at large, current health protection agencies suggest more frequent testing for those at increased risk of HIV transmission, such as those in the MSM community. However, more frequent testing for those at higher risk relies heavily on the preliminary step of patient disclosure of sexual practices to health care providers. MATERIALS AND METHODS An exploratory cross-sectional study was conducted in order to gain a better understanding of the relationship between sexual health variables and the disclosure of sexual identity to health care providers by MSM service members. A convenience sample of MSM currently serving in the U.S. military services (N = 354) was used to collect demographic data, sexual health and history, and opinions concerning medical treatment and HIV. Analyses of the data were conducted using univariate analysis and multivariate regression. RESULTS Men of color were more likely to report a higher degree of sexual identification transparency with their health care providers, which deviates from the civilian population. Pre-exposure prophylaxis (PrEP) uptake was increased among individuals who were more transparent with their health care providers. CONCLUSIONS Findings from this study indicate that feeling more comfortable sharing one's sexual identification with a health care provider results in increased engagement with HIV prevention measures. Potential implications for the Military Health System are the advancement of preventive sexual health screening procedures and the development and revision of policies that promote positive outcomes for gender and sexual minorities.

Abstract
We conducted a web-based survey targeting physicians in specialties of treating sexually transmitted infection (STI) and/or human immunodeficiency virus (HIV) patients to understand the current STI/HIV care practices and their acceptability of and barriers to the prescription of pre-exposure prophylaxis (PrEP) in Japan. A descriptive analysis was used to summarize survey responses. Univariate and multivariable logistic regression were performed to identify factors associated with willingness to prescribe PrEP. Of 316 survey respondents, 57 were specialized in HIV, 90 STI/Urology/Proctology, 55 Obstetrics/Gynecology, and 114 General Practice/Internal Medicine/Dermatology. Proportion of HIV-specialized physicians who interview the patients about risk behaviors tended to be higher than other physician groups (84.2% vs. 54.8%, 47.3%, and 50.9%, respectively), and 53 - 75% of non-HIV-specialized physicians reported that they were incapable of making decisions on HIV medications. Higher PrEP knowledge enhanced the willingness to recommend and prescribe PrEP drugs (odds ratio: 2.31, 95% confidence interval: 1.30-4.10, p = 0.0044), and 45.4% physicians with no PrEP knowledge raised the concern of incapability to respond and manage when an individual is infected with HIV. Educational opportunities on management and prevention measures for both STI and HIV may encourage non-HIV-specialized physicians to be involved in HIV care and to enhance initiation of HIV tests and adoption of PrEP.

Abstract
INTRODUCTION Of 37.7 million people living with HIV in 2020, 6.1 million still do not know their HIV status. We synthesize evidence on concurrent HIV testing among people who tested for other sexually transmitted infections (STIs). METHODS We conducted a systematic review using five databases, HIV conferences and clinical trial registries. We included publications between 2010 and May 2021 that reported primary data on concurrent HIV/STI testing. We conducted a random-effects meta-analysis and meta-regression of the pooled proportion for concurrent HIV/STI testing. RESULTS We identified 96 eligible studies. Among those, 49 studies had relevant data for a meta-analysis. The remaining studies provided data on the acceptability, feasibility, barriers, facilitators, economic evaluation and social harms of concurrent HIV/STI testing. The pooled proportion of people tested for HIV among those attending an STI service (n = 18 studies) was 71.0% (95% confidence intervals: 61.0-80.1, I2 = 99.9%), people tested for HIV among those who were tested for STIs (n = 15) was 61.3% (53.9-68.4, I2 = 99.9%), people tested for HIV among those who were diagnosed with an STI (n = 13) was 35.3% (27.1-43.9, I2 = 99.9%) and people tested for HIV among those presenting with STI symptoms (n = 3) was 27.1% (20.5-34.3, I2 = 92.0%). The meta-regression analysis found that heterogeneity was driven mainly by identity as a sexual and gender minority, the latest year of study, country-income level and region of the world. DISCUSSION This review found poor concurrent HIV/STI testing among those already diagnosed with an STI (35.3%) or who had symptoms with STIs (27.1%). Additionally, concurrent HIV/STI testing among those tested for STIs varied significantly according to the testing location, country income level and region of the world. A few potential reasons for these observations include differences in national STI-related policies, lack of standard operation procedures, clinician-level factors, poor awareness and adherence to HIV indicator condition-guided HIV testing and stigma associated with HIV compared to other curable STIs. CONCLUSIONS Not testing for HIV among people using STI services presents a significant missed opportunity, particularly among those diagnosed with an STI. Stronger integration of HIV and STI services is urgently needed to improve prevention, early diagnosis and linkage to care services.

Abstract
BACKGROUND Sexually transmitted infections (STIs) are one of the leading causes of health, and economic burdens in the developing world, leading to considerable morbidity, mortality, and stigma. The incidence and prevalence of the four curable STIs viz. syphilis, gonorrhoea, chlamydia, and trichomoniasis vary remarkably across different geographical locations. In India, the prevalence of four curable STI among general populations is in between 0 to 3.9 percent. However, it is assumed that STI prevalence is much higher among subpopulations practicing high-risk behaviour. Like men who have sex with men (MSM), transgender (TG), injecting drug users (IDU), and female sex workers (FSW). OBJECTIVES In the present circumstances, a systematic review is necessary to integrate the available data from previously published peer-reviewed articles and published reports from several competent authorities to provide the prevalence and geographical distribution of the four curable STIs among the key population of India. METHODS All available articles will be retrieved from PubMed, Google Scholar, Cochrane database, Scopus, Science Direct, and the Global Health network using the appropriate search terms. The data will be extracted through data extraction form as per PICOS (population, intervention, comparison, outcome, study design) framework. Risk of bias and quality assessment will be performed according to the situation with the help of available conventional protocol. DISCUSSION The future systematic review, generated from the present protocol, may provide evidence of the prevalence and geographical distribution of the four curable STIs among the key population of India. We hope that the findings of the future systematic review will strengthen the existing surveillance system in India, to determine the above-mention STIs prevalence among key populations in India.

Abstract
BACKGROUND HIV acquisition among Female Sex Workers (FSWs) is 30 times higher than the acquisition rate among females in the respective general population. A higher HIV burden in FSWs challenges the prevention and control of the virus in other population groups. However, there is inadequate evidence on the burden of HIV among FSWs in Ethiopia. This study was conducted to assess the extent of HIV and associated factors among FSWs in the country. METHODS This was a cross-sectional study that involved a total of 6,085 FSWs. The participants were selected using a respondent-driven sampling technique (RDS). FSWs who lived at the study sites for at least a month before the study time were considered eligible for recruitment. The study was conducted from January 01 to June 30, 2020 in 16 cities across Ethiopia. A mixed-effect logistic regression model was applied to determine factors associated with HIV positivity. FINDINGS The pooled HIV prevalence among FSWs in this study was 18·7% (95% CI: 17·8, 19·7) with considerable variation across cities. The highest HIV prevalence was observed in Bahir Dar city, 28·2% (95% CI: 23·9, 33.0) and the lowest was seen in Shashemene city, 14.0% (95% CI: 10·2, 18·9). The odds of HIV positivity in FSWs was associated with being older than 35 years of age (AOR = 8·1; 95% CI: 6·1, 10·3), reactive for Treponema Pallidum (AOR = 2·6; 95% CI: 1·0, 3·4), being widowed (OR = 2·2; 95% CI: 1·6, 2·9), not able to read and write (OR = 2·0; 95% CI: 1·5, 2·4), incidence of condom breakage (OR = 1·5; 95% CI: 1·2, 1·7) and having a history of STIs (OR = 1·3; 95% CI: 1·1, 1·6). INTERPRETATION One in five FSWs was HIV positive. HIV prevalence was higher in the older age groups and in those who were positive for Treponema Pallidum (Syphilis). The findings indicated the importance of strengthening HIV prevention and control in FSWs to achieve the national goal to eliminate HIV by 2030. FUNDING The study was supported by The Ethiopian Ministry of Health through the Federal HIV/AIDS Prevention and Control Office.

Abstract
BACKGROUND We provided sexually transmitted infection (STI) screening and facilitated partner notification and treatment among women participating in a periconception HIV prevention program in southwestern Uganda to understand follow-up STI incidence. METHODS Women at-risk for HIV exposure while planning for pregnancy completed laboratory screening for chlamydia, gonorrhea, trichomoniasis, and syphilis at enrollment and 6 months of follow-up and/or incident pregnancy; facilitated partner notification and treatment were offered for those with positive tests. We performed a logistic regression to determine correlates of follow-up STI. RESULTS Ninety-four participants completed enrollment STI screening with a median age of 29 (IQR 26-34); 23 (24%) had ≥1 STI. Of the 23 participants with enrollment STI(s), all completed treatment and 19 (83%) returned for follow-up; 18 (78%) reported delivering partner notification cards and discussing STIs with partner(s), and 14 (61%) reported all partners received STI treatment. Of the 81 (86%) who successfully completed follow-up STI screening, 17 (21%) had ≥1 STI. The STI incidence rate was 29.0 per 100 person-years. In univariable regression analysis, enrollment STI, younger age, less education, and alcohol consumption were all significantly associated with follow-up STI. CONCLUSIONS We demonstrated high enrollment and follow-up STI rates and moderate participant-reported partner treatment among women planning for pregnancy in Uganda despite partner notification and treatment. Novel STI partner notification and treatment interventions are needed to decrease the STI burden, especially among women planning for and with pregnancy.

Abstract
BACKGROUND Nonviral sexually transmitted infections (STIs) increase risk of sexually acquired human immunodeficiency virus (HIV) infection. Updated risk estimates carefully scrutinizing temporality bias of studies are needed. METHODS We conducted a systematic review (PROSPERO CRD42018084299) of peer-reviewed studies evaluating variation in risk of HIV infection among high-risk heterosexuals diagnosed with any of: Chlamydia trachomatis, Mycoplasma genitalium, Neisseria gonorrhoeae, Treponema pallidum, and/or Trichomonas vaginalis. We searched PubMed, Web of Science, and Embase databases through December 2017 and included studies where STIs and HIV were assessed using laboratory tests or medical examinations and where STI was diagnosed before HIV. After dual screening, data extraction, and risk of bias assessment, we meta-analytically pooled risk ratios (RRs). RESULTS We found 32 eligible studies reporting k = 97 effect size estimates of HIV acquisition risk due to infection with one of the abovementioned STIs. Most data were based on women engaged in sex work or other high-risk occupations in developing countries. Many studies did not measure or adjust for known confounders, including drug injection and condom use, and most were at medium or high risk of bias because of the potential for undetected HIV infection to have occurred before STI infection. Human immunodeficiency virus acquisition risk increased among women infected with any pathogen; the effect was greatest for women infected with Mycoplasma genitalium (RR, 3.10; 95% confidence interval [CI], 1.63-5.92; k = 2) and gonorrhea (RR, 2.81; 95% CI, 2.25-3.50; k = 16) but also statistically significant for women infected with syphilis (RR, 1.67; 95% CI, 1.23-2.27; k = 17), trichomonas (RR, 1.54; 95% CI, 1.31-1.82; k = 17), and chlamydia (RR, 1.49; 95% CI, 1.08-2.04; k = 14). For men, data were space except for syphilis (RR, 1.77; 95% CI, 1.22-2.58; k = 5). CONCLUSION Nonviral STI increases risk of heterosexual HIV acquisition, although uncertainty remains because of risk of bias in primary studies.

Abstract
Background In the past years, we observed a sharp increase of Syphilis, especially among male who have sex with male (MSM), either HIV-infected, or on pre-exposure prophylaxis (PrEP). Our aim was to assess syphilis prevalence and incidence among people living with HIV (PLWH) and PrEP users. Methods PLWH were included from 2010 to 2020 and PrEP users from 2016 to 2020 from the Dat’AIDS French cohort. We calculated syphilis prevalence and incidences for first infections, re-infections, and iterative infections (> 2 times). T-Tests, Wilcoxon tests and Chi2 test were used for descriptive analysis and multivariate logistic regression models were used to estimate Odds ratios (OR) and 95% confidence intervals (95% CI) for factors associated with syphilis. Results Among the 8 583 PLWH, prevalence of subject with past or present syphilis was 19.9%. These subjects were more likely MSM or transgender and aged over 35 years, but prevalence was lower in AIDS subjects. Same pattern was seen for incident infection and re-infection. Incidence was 3.8 per 100 person-years for infection and 6.5 per 100 person-years for re-infection. Among 1 680 PrEP users, syphilis prevalence was 25.8%, with an estimated 7.2% frequency of active syphilis. Risk of syphilis infection was higher in male and increased with age. Incidence was 11.2 per 100 person-years for infection and 11.1 per 100 person-years for re-infection. Conclusion Syphilis prevalence and incidence were high, especially in older MSM with controlled HIV infection and PrEP users, enhancing the need to improve syphilis screening and behavioral risk reduction counseling among high-risk subjects.

Abstract
BACKGROUND Accurate same-day sexually transmitted infection (STI) diagnostic testing is generally unavailable, leading to syndromic management with high rates of overtreatment and undertreatment. We analyzed the ease of integration of the Visby STI Panel into clinical practice, studied acceptance by patients and clinic personnel, and assessed the potential to inform accurate treatment decisions. METHODS In a cross-sectional single-visit study of 55 women aged 18 to 56 years, women self-collected vaginal swab samples that were analyzed using the Visby STI Panel for Chlamydia trachomatis, Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV). Results were compared with standard-of-care clinic results from send-out laboratory polymerase chain reaction tests. Surveys assessed patient and device operator experiences with the Visby STI Panel and clinicians' perceived need for and acceptance of the device. Time parameters were measured to evaluate the impact on clinical workflow, and syndromic treatment decisions were compared with anticipated treatment based on the Visby STI Panel results. RESULTS Patients strongly agreed that sample self-collection was easy, and operators reported the device easy to use. Clinicians valued the rapid return of results, and patients were comfortable waiting up to 30 minutes to receive them. In 13 of 15 cases, the Visby STI Panel correctly identified undertreated patients as infected and correctly identified all 33 incidences of overtreatment. CONCLUSIONS Clinical adoption of the Visby STI Panel into primary care clinics and doctors' offices could reduce overtreatment and undertreatment of STIs. If integrated efficiently into the clinical workflow, the test would have minimal impact on staff time and visit duration for patients.

Abstract
OBJECTIVES Sexually transmitted infections (STIs) cause significant morbidity among women with HIV and increase HIV transmission. We estimated the prevalence of four STIs among women with HIV in sub-Saharan Africa (SSA) and compared prevalence among women with and without HIV. DESIGN Systematic review and meta-analysis. METHODS We searched for studies published 1 January 1999 to 19 December 2019 reporting prevalence of gonorrhea, chlamydia, trichomoniasis, or Mycoplasma genitalium among women with HIV in SSA. We excluded studies conducted in high-risk groups (e.g. female sex workers). We extracted data on laboratory-confirmed STIs among women with HIV, and when included, among women without HIV. We estimated pooled prevalence for each STI among women with HIV using inverse variance heterogeneity meta-analysis, compared prevalence to women without HIV, and examined the influences of region, clinical setting, and pregnancy status in subgroup analyses. RESULTS We identified 3756 unique records; 67 studies were included in the meta-analysis. Prevalence of gonorrhea, chlamydia, trichomoniasis, and M. genitalium was 3.5, 4, 15.6, and 10.2%, respectively. Chlamydia prevalence was lower in Eastern (2.8%) than in Southern (12.5%) and West/Central (19.1%) Africa combined. Prevalence of chlamydia and trichomoniasis was higher among pregnant (8.1%, 17.6%) than nonpregnant (1.7%, 12.3%) women. All STIs were more prevalent among women with than without HIV (relative risks ranging 1.54-1.89). CONCLUSION STIs are common among women with HIV in SSA, and more common among women with than without HIV. Integrated STI and HIV care could substantially impact STI burden among women with HIV, with potential downstream impacts on HIV transmission.

Abstract
Studies have consistently shown that diagnosis of a syphilis infection increases the risk of human immunodeficiency virus (HIV) infection. This study examines patterns in HIV incidence among men following a Primary and Secondary (P&S) syphilis diagnosis. P&S syphilis cases among men reported to the Texas Department of State Health Services between January 2010 and June 2018 were linked to the Enhanced HIV/AIDS Reporting System. Risk factors for HIV diagnosis were identified using univariate and multivariate extended Cox proportional hazards models. The 9113 men with syphilis without a concurrent or prior HIV diagnosis contributed a cumulative 35,674 person-years with a mean follow-up time of 3.9 years. The multivariate model showed that among men with a P&S syphilis diagnosis, age, race/ethnicity, transmission risk, comorbid STDs, subsequent STDs, and syphilis diagnosing facility were independently associated with a new HIV diagnosis. The results highlight disparities in HIV diagnoses, despite current prevention recommendations. Reducing these disparities will require multi-level, comprehensive interventions that are appropriate for the diverse populations around the state.

Abstract
A worldwide estimate of over one million STIs are acquired daily and there is a desperate need for effective preventive as well as therapeutic measures to curtail this global health burden. Vaccines have been the most effective means for the control and potential eradication of infectious diseases; however, the development of vaccines against STIs has been a daunting task requiring extensive research for the development of safe and efficacious formulations. Nanoparticle-based vaccines represent a promising platform as they offer benefits such as targeted antigen presentation and delivery, co-localized antigen-adjuvant combinations for enhanced immunogenicity, and can be designed to be biologically inert. Here we discuss promising types of nanoparticles along with outcomes from nanoparticle-based vaccine preclinical studies against non-viral STIs including chlamydia, syphilis, gonorrhea, and recommendations for future nanoparticle-based vaccines against STIs.

Abstract
Background High-risk sexual behaviors(HRSBs) among young adults are key risk for Sexually Transmitted Infections(STIs), HIV and unplanned pregnancies. WHO has identified the 15-24years age-group as high-risk for STIs. Students at Higher Learning Institutions(HLIs) may be at higher risk because they are free of immediate parental-supervision, are a transient migratory population, probably at peak-years of sexual activity. In Tanzania, information is limited on sexual and preventive behaviours among young adults in HLIs. We describe risky sexual behaviours and preventive practices among young adults attending HLIs in Mbeya-Tanzania. Methods We conducted a cross-sectional study from March2019 to January2020 among randomly selected students aged 18-24years enrolled in HLIs within Mbeya. Probability proportional to size was used to determine total student number from each HLI. We used a self-administered questionnaire to collect information on sexual health education, activity, behaviour and STI knowledge. Results Total of 504students were enrolled with mean age of 21.5(SD 1.74)years. Total of 446(88.5%) students reported ever having had sex. Mean-age at first sex was 18.4years and 9.9% reported sexual debut <15years. A higher proportion of male students(57%) reported sexual debut with non-steady partners than females(37.9%). Lack of condom use at sexual debut was reported by 52% of the participants. Consistent condom use during past 4-weeks was reported at 33% and 16.5% among males and females, respectively. About 1 in 10 students reported forced sex by someone they were dating. Sex under the influence of alcohol was reported by 24% of the students. Nearly 8 in 10 (78.7%) students have heard of STIs, but only 16% were aware STIs can be asymptomatic. Conclusion STI prevention programs need to recognize young adults in HLIs as at-risk population; and advocate targeted messages to minimize risk to acquiring STIs, counseling and support for those experiencing sexual violence, promote condom use and safer-sex negotiation skills.

Abstract
BACKGROUND Men who have sex with men (MSM) who have bacterial sexually transmitted infections (STIs) are at increased risk for HIV infection. We enhanced and updated past summary risk estimates. METHODS We systematically reviewed (PROSPERO No. CRD42018084299) peer-reviewed studies assessing the risk of HIV infection among MSM attributable to Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), Neisseria gonorrhoeae (NG), Treponema pallidum (TP), and/or Trichomonas vaginalis (TV). We searched 3 databases through December 2017. We excluded studies with self-reported data or simultaneous STI and HIV assessment. We conducted dual screening and data extraction, meta-analytically pooled risk ratios (RRs), and assessed potential risk of bias. RESULTS We included 26 studies yielding 39 RR (k) for HIV acquisition due to one of TP, NG, or CT. We did not identify eligible data for MG or TV, or for HIV transmission. HIV acquisition risk increased among MSM infected with TP (k = 21; RR, 2.68, 95% confidence interval [CI], 2.00-3.58), NG (k = 11; RR, 2.38; 95% CI, 1.56-3.61), and CT (k = 7; RR, 1.99; 95% CI, 1.59-2.48). Subanalysis RRs for all 3 pathogens were ≥1.66 and remained statistically significant across geography and methodological characteristics. Pooled RR increased for data with the lowest risk of bias for NG (k = 3; RR, 5.49; 95% CI, 1.11-27.05) and TP (k = 4; RR, 4.32; 95% CI, 2.20-8.51). We observed mostly moderate to high heterogeneity and moderate to high risk of bias. CONCLUSIONS Men who have sex with men infected with TP, NG, or CT have twice or greater risk of HIV acquisition, although uncertainties exist because of data heterogeneity and risk of bias.

JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2021; 43:1047-1054.e2. [PMID: 33932575 DOI: 10.1016/j.jogc.2021.04.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 04/05/2021] [Accepted: 04/06/2021] [Indexed: 11/16/2022]
Abstract
OBJECTIVE Missed screening opportunities may contribute to the rising rates of sexually transmitted and blood borne infections (STBBIs) in Manitoba. This study sought to determine the proportion of women who are screened for syphilis and human immunodeficiency virus (HIV) when admitted with pelvic inflammatory disease (PID). METHODS We performed a retrospective analysis of all inpatient admissions for PID over 3 discrete years (fiscal years 2007, 2012, 2017) at a single tertiary care centre. Data extracted from medical records included STBBI screening performed, clinical signs at presentation, and history of PID or STBBI. To improve the accuracy of our estimates, we complemented the records data with population data from Manitoba. We evaluated predictive factors influencing any or concurrent STBBI screening using bivariate analysis for significance (P < 0.05). RESULTS One hundred and five admissions met inclusion criteria. Syphilis and HIV screening was ordered concurrently with chlamydia and gonorrhoea screening in 6 (6%) of encounters and was ordered at any point during admission for PID in 28 (27%). A history of substance abuse (odds ratio [OR] 4.94 [95% CI 1.62-15.05] for syphilis screening and OR 6.94 [95% CI 2.38-20.23] for HIV screening) and a positive gonorrhea result while admitted (OR 3.40 [95% CI 1.06-10.88] for syphilis screening) were strongly associated with receiving any screening. Reporting multiple sexual partners was also strongly associated with receiving any STBBI screening while admitted (OR 19.44 [95% CI 2.01-187.92] and OR 15.00 [95% CI 1.58-142.70] for syphilis and HIV screening, respectively). CONCLUSION A minority of patients were screened for syphilis and HIV while admitted for PID. This study highlights a missed opportunity to screen for STBBI among sexually active women.

Sexually Transmitted Infection Prevalence Among Women at Risk for HIV Exposure Initiating Safer Conception Care in Rural, Southwestern Uganda. Sex Transm Dis 2021; 47:e24-e28. [PMID: 32404858 DOI: 10.1097/olq.0000000000001197] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/26/2022]
Abstract
BACKGROUND Knowledge of sexually transmitted infection (STI) prevalence and risk factors is important to the development of tenofovir-based preexposure prophylaxis (PrEP) and safer conception programming. We introduced STI screening among women at risk for HIV exposure who were participating in a safer conception study in southwestern Uganda. METHODS We enrolled 131 HIV-uninfected women, planning for pregnancy with a partner living with HIV or of unknown HIV serostatus (2018-2019). Women were offered comprehensive safer conception counseling, including PrEP. Participants completed interviewer-administered questionnaires detailing sociodemographics and sexual history. We integrated laboratory screening for chlamydia, gonorrhea, trichomoniasis, and syphilis as a substudy to assess STI prevalence. Multivariable logistic regression was used to determine correlates. RESULTS Ninety-four women completed STI screening (72% of enrolled). Median age was 30 (interquartile range, 26-34) years, and 94% chose PrEP as part of safer conception care. Overall, 24% had STIs: 13% chlamydia, 2% gonorrhea, 6% trichomoniasis, 6% syphilis, and 3% ≥2 STI. Sexually transmitted infection prevalence was associated with younger age (adjusted odds ratio [AOR], 0.87; 95% confidence interval [CI], 0.77-0.99), prior stillbirth (AOR, 5.04; 95% CI, 1.12-22.54), and not feeling vulnerable to HIV (AOR, 16.33; 95% CI, 1.12-237.94). CONCLUSIONS We describe a 24% curable STI prevalence among women at risk for HIV exposure who were planning for pregnancy. These data highlight the importance of integrating laboratory-based STI screening into safer conception programs to maximize the health of HIV-affected women, children, and families.

Pillay J, Wingert A, MacGregor T, Gates M, Vandermeer B, Hartling L. Screening for chlamydia and/or gonorrhea in primary health care: systematic reviews on effectiveness and patient preferences. Syst Rev 2021; 10:118. [PMID: 33879251 PMCID: PMC8056106 DOI: 10.1186/s13643-021-01658-w] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Accepted: 03/31/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND We conducted systematic reviews on the benefits and harms of screening compared with no screening or alternative screening approaches for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) in non-pregnant sexually active individuals, and on the relative importance patients' place on the relevant outcomes. Findings will inform recommendations by the Canadian Task Force on Preventive Health Care. METHODS We searched five databases (to January 24, 2020), trial registries, conference proceedings, and reference lists for English and French literature published since 1996. Screening, study selection, and risk of bias assessments were independently undertaken by two reviewers, with consensus for final decisions. Data extraction was conducted by one reviewer and checked by another for accuracy and completeness. Meta-analysis was conducted where appropriate. We used the GRADE approach to rate the certainty of the evidence. The Task Force and content experts provided input on determining thresholds for important effect sizes and on interpretation of findings. RESULTS Of 41 included studies, 17 and 11 reported on benefits and harms of screening, respectively, and 14 reported on patient preferences. Universal screening for CT in general populations 16 to 29 years of age, using population-based or opportunistic approaches achieving low screening rates, may make little-to-no difference for a female's risk of pelvic inflammatory disease (PID) (2 RCTs, n=141,362; 0.3 more in 1000 [7.6 fewer to 11 more]) or ectopic pregnancy (1 RCT, n=15,459; 0.20 more per 1000 [2.2 fewer to 3.9 more]). It may also not make a difference for CT transmission (3 RCTs, n=41,709; 3 fewer per 1000 [11.5 fewer to 6.9 more]). However, benefits may be achieved for reducing PID if screening rates are increased (2 trials, n=30,652; 5.7 fewer per 1000 [10.8 fewer to 1.1 more]), and for reducing CT and NG transmission when intensely screening high-prevalence female populations (2 trials, n=6127; 34.3 fewer per 1000 [4 to 58 fewer]; NNS 29 [17 to 250]). Evidence on infertility in females from CT screening and on transmission of NG in males and both sexes from screening for CT and NG is very uncertain. No evidence was found for cervicitis, chronic pelvic pain, or infertility in males from CT screening, or on any clinical outcomes from NG screening. Undergoing screening, or having a diagnosis of CT, may cause a small-to-moderate number of people to experience some degree of harm, mainly due to feelings of stigmatization and anxiety about future infertility risk. The number of individuals affected in the entire screening-eligible population is likely smaller. Screening may make little-to-no difference for general anxiety, self-esteem, or relationship break-up. Evidence on transmission from studies comparing home versus clinic screening is very uncertain. Four studies on patient preferences found that although utility values for the different consequences of CT and NG infections are probably quite similar, when considering the duration of the health state experiences, infertility and chronic pelvic pain are probably valued much more than PID, ectopic pregnancy, and cervicitis. How patients weigh the potential benefits versus harms of screening is very uncertain (1 survey, 10 qualitative studies); risks to reproductive health and transmission appear to be more important than the (often transient) psychosocial harms. DISCUSSION Most of the evidence on screening for CT and/or NG offers low or very low certainty about the benefits and harms. Indirectness from use of comparison groups receiving some screening, incomplete outcome ascertainment, and use of outreach settings was a major contributor to uncertainty. Patient preferences indicate that the potential benefits from screening appear to outweigh the possible harms. Direct evidence about which screening strategies and intervals to use, which age to start and stop screening, and whether screening males in addition to females is necessary to prevent clinical outcomes is scarce, and further research in these areas would be informative. Apart from the evidence in this review, information on factors related to equity, acceptability, implementation, cost/resources, and feasibility will support recommendations made by the Task Force.

Acceptability of dual HIV/syphilis rapid test in community- and home-based testing strategy among transgender women in Buenos Aires, Argentina. Int J STD AIDS 2021; 32:501-509.

Abstract
BACKGROUND Little is known of acceptability and feasibility of dual HIV and syphilis rapid tests in community- and home-based provider-initiated strategies among transgender women (TGW), in Latin America. Objectives were (1) to assess the acceptability of this strategy and, (2) to determine the percentage of positive results of HIV and syphilis, analyze the correlates of HIV or syphilis positive results, and measure the rates of effective referral and treatment completion among TGW. METHODS A multidisciplinary team tested 89 TGW in Buenos Aires. An acceptability survey was administered after the HIV/syphilis Duo test was used. All confirmed cases were referred for treatment initiation. RESULTS We found high levels of acceptability (98.8%) of this strategy among TGW. However, only 60.7% preferred simultaneous HIV and syphilis diagnosis test. Moreover, we found 9% of positive results of HIV, 51.7% of syphilis, and 3.4% of positive results for both infections. Only not being tested before was associated with an HIV positive result, and only low level of education was associated with a positive syphilis result. Among 8 TGW who tested positive for HIV, 37.5% (n = 3) started antiretroviral therapy. Of 46 who tested positive for syphilis, only 73.9% (n = 34) were effectively referred and from 23 who started treatment, only 39.1% completed it. CONCLUSIONS Community- and home-based dual HIV and syphilis rapid test is a feasible and highly acceptable approach for this hard-to-reach population. Implementing similar strategies could improve screening uptake and accessibility. However, these results highlight the need to improve strategies for treatment uptake, in order to reduce morbidity and risk of onward transmission.

AAS Open Res 2020; 3:41. [PMID: 37168604 PMCID: PMC10080207 DOI: 10.12688/aasopenres.13123.1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/18/2020] [Indexed: 11/20/2022] Open
Abstract
Background: High-risk sexual behaviours (HRSBs) among young adults are a key risk for Sexually Transmitted Infections (STIs), HIV and unplanned pregnancies. The World Health Organization has identified the 15-24 year age-group as high-risk for STIs. Students at Higher Learning Institutions (HLIs) may be at higher risk because they are free of immediate parental supervision, a transient migratory population, and probably at peak years of sexual activity. Here, we describe risky sexual behaviours and preventive practices among young adults attending HLIs in Mbeya, Tanzania. Methods: Cross-sectional study was conducted from March 2019 to January 2020 among students aged 18-24 years enrolled in HLIs within Mbeya. A self-administered questionnaire was used to collect information on sexual health education, activity, behaviour and STI knowledge. Results: 504 students were enrolled; mean age of 21.5 (SD 1.74) years. 377 (74.8%) students were sexually active. Mean age of first sexual encounter was 18.4 years and 11.6% reported their sexual debut was <15 years. A higher proportion of male students (59.7%) reported their sexual debut with non-steady partners compared with female students (40.9%). Lack of condom use at sexual debut was reported by 43.3% of sexually active students. Consistent condom use during the past 4-weeks was reported at 23.3% and 16.9% among men and women, respectively. Almost 1 in 10 students reported being forced into having sex by someone they were dating. Sex under the influence of alcohol was reported by 25.5% of the students. Nearly 7 in 10 (77%) students had heard of STIs, but only 15% were aware STIs could be asymptomatic. Conclusion: STI prevention programs need to recognize young adults in HLIs as an at-risk population. HLIs must advocate targeted messages to minimize risks to acquiring STIs, offer counselling and support for those experiencing sexual violence, and promote condom use and safer-sex negotiation skills.

Abstract
Background: Sexually transmitted infections (STIs) are a major public health problem in developing countries, and treatment with the right medicine at the right time is necessary to reduce transmission and improve sexual and reproductive health. Laboratory diagnosis has undergone changes in the recent years. The new generation tests are not cost-effective in resource-poor settings. Papanicolaou smear (Pap smear) of the cervix is a simple, quick, and inexpensive screening procedure for cervical cancer that can also give a clue to the presence of STIs. Methods: A hospital-based cross-sectional design with fifty patients was conducted studied. The initial diagnosis based on clinical findings and routine laboratory results was compared with the final diagnosis incorporating Pap smear results. Results: The Pap smear was abnormal in 96%, and the abnormalities were koilocytosis (30%), endocervicitis (24%), Trichomonas vaginalis (16%), multinucleated giant cells (10%), low-grade squamous intraepithelial lesion (10%), and clue cells (8%). Pap smear could diagnose an infection in 64%, of which 38% were asymptomatic. Clinical and Pap smear correlation was found only in 26% of the patients. Conclusion: Along with the conventional methods, Pap smear can be a valuable tool in diagnosing STIs. This can detect asymptomatic infections, not detected by conventional methods, thus preventing complications and further spread in the community. Asymptomatic human papillomavirus (HPV) infection and trichomoniasis are the two STIs that can be easily detected by Pap smear. By detecting asymptomatic cervical HPV infection, the patients at risk for carcinoma of the cervix can be identified and referred to gynecology department for further management.

Abstract
BACKGROUND Pregnancy coercion (PC), defined as a restriction of women's reproductive autonomy, may be associated with increased HIV and sexually transmitted infection (STI) risk. However, there are few empirical studies defining the association between PC and HIV risk, particularly among vulnerable African American women. SETTING AND METHODS African American women (N = 560), ages 17-24, completed an audio computer-assisted self-interview assessing PC prevalence and its association with HIV/STI risk. Women were screened for prevalent STIs using polymerase chain reaction assays. Multivariate logistic and linear regressions evaluated the association of PC and multiple HIV/STI risk-associated outcomes. RESULTS Women who had experienced PC in the last 3 months, relative to those not experiencing PC, were 78% more likely to test positive for an STI [adjusted odds ratio = 1.78, 95% confidence interval (CI) = 1.10 to 2.90]. Among women who experienced PC, odds of noncondom use in their last sexual encounter were 3.45-fold greater relative to women not experiencing PC (95% CI = 1.55 to 7.85). Women who experienced PC had lower condom use intentions (coefficient, -1.31, P = 0.002), greater fear of condom negotiation, and perceived more barriers to condom use (coefficients, 3.89 and 5.74, respectively, both P < 0.001). Women who experienced PC had 1.98 (95% CI = 1.22 to 3.21) and 1.82 (95% CI = 1.09 to 3.04) odds of depression and HIV worry relative to women not experiencing PC. CONCLUSION Among African American women, PC was associated with a range of adverse sexual health outcomes and HIV/STI-related behaviors and attitudes. The findings underscore the need for promoting gender-equitable social norms in HIV prevention interventions.

Abstract
Renewed interest in developing vaccines against Neisseria gonorrhoeae has been sparked by the increasing threat of gonococcal antimicrobial resistance (AMR) and growing optimism that gonococcal vaccines are biologically feasible. Evidence suggests serogroup B Neisseria meningitidis vaccines might provide some cross-protection against N. gonorrhoeae, and new gonococcal vaccine candidates based on several approaches are currently in preclinical development. To further stimulate investment and accelerate development of gonococcal vaccines, greater understanding is needed regarding the overall value that gonococcal vaccines might have in addressing public health and societal goals in low-, middle-, and high-income country contexts and how future gonococcal vaccines might be accepted and used, if available. In January 2019, the World Health Organization (WHO) convened a multidisciplinary international group of experts to lay the groundwork for understanding the potential health, economic, and societal value of gonococcal vaccines and their likely acceptance and use, and for developing gonococcal vaccine preferred product characteristics (PPCs). WHO PPCs describe preferences for vaccine attributes that would help optimize vaccine value and use in meeting the global public health need. This paper describes the main discussion points and conclusions from the January 2019 meeting of experts. Participants emphasized the need for vaccines to control N. gonorrhoeae infections with the ultimate goals of preventing adverse sexual and reproductive health outcomes (e.g., infertility) and reducing the impact of gonococcal AMR. Meeting participants also discussed important PPC considerations (e.g., vaccine indications, target populations, and potential immunization strategies) and highlighted crucial research and data needs for guiding the value assessment and PPCs for gonococcal vaccines and advancing gonococcal vaccine development.

Abstract
Background Adolescent girls and young women (AGYW) aged 15–24 years have among the highest risk for HIV and other sexually transmitted infections (STI) across sub-Saharan Africa. A latent class analysis (LCA) was conducted to identify intersecting social- and structural-level determinants of HIV/STI acquisition among AGYW in Ethiopia. Methods AGYW were recruited from venues using time-location sampling, completing an interviewer-administered behavioral survey and biological testing for HIV, syphilis, and chlamydia. LCA was used to identify distinct groups, defined by social- and structural-level determinants of HIV/STI risk, among AGYW. Prevalence ratios (PR) and 95% confidence intervals (CI) compared differences in HIV/STI prevalence by group. Results A total of 1,501 AGYW were enrolled across Addis Ababa (March–May 2018) and Gambella (June–July 2019). We identified three patterns of vulnerability defined by schooling status, migration history, food insecurity, orphan status, social support, and employment. We labeled these groups as “highly vulnerable” (representing ~21% of the population), “stable, out-of-school, migrated” (~42%), and “stable, in-school, never migrated” (~37%). STI prevalence was nearly two-fold higher among AGYW in the “highly vulnerable” group compared to AGYW in the “stable, in-school, never migrated” group (PR 1.93; 95% CI 1.33, 2.80). Conclusions Characterizing patterns of vulnerability among AGYW that reflect higher-level social and structural factors can help facilitate early identification of AGYW at the highest risk of HIV/STI acquisition, thus differentiating groups of AGYW who may most benefit from targeted HIV prevention interventions during adolescence and early adulthood.

Abstract
This report (hereafter referred to as STD QCS) provides CDC recommendations to U.S. health care providers regarding quality clinical services for sexually transmitted diseases (STDs) for primary care and STD specialty care settings. These recommendations complement CDC's Sexually Transmitted Diseases Treatment Guidelines, 2015 (hereafter referred to as the STD Guidelines), a comprehensive, evidence-based reference for prevention, diagnosis, and treatment of STDs. STD QCS differs from the STD Guidelines by specifying operational determinants of quality services in different types of clinical settings, describing on-site treatment and partner services, and indicating when STD-related conditions should be managed through consultation with or referral to a specialist. These recommendations might also help in the development of clinic-level policies (e.g., standing orders, express visits, specimen panels, and reflex testing) that can facilitate implementation of the STD Guidelines. CDC organized the recommendations for STD QCS into eight sections: 1) sexual history and physical examination, 2) prevention, 3) screening, 4) partner services, 5) evaluation of STD-related conditions, 6) laboratory, 7) treatment, and 8) referral to a specialist for complex STD or STD-related conditions.CDC developed the recommendations by synthesizing relevant, evidence-based guidelines and recommendations issued by other experts; reviewing current practice in the United States; soliciting Delphi ratings by subject matter experts on STD care in primary care and STD specialty care settings; discussing the scientific evidence supporting the proposed recommendations at a consultation meeting of experts and institutional stakeholders held November 20, 2015, in Atlanta, Georgia; conducting peer reviews of draft recommendations and supporting evidence; and discussing draft recommendations and supporting evidence during meetings of the CDC/Health Resources and Services Administration Advisory Committee on HIV, Viral Hepatitis, and STD Prevention and Treatment STD Work Group. These recommendations are intended to help health care providers in primary care or STD specialty care settings offer STD services at their clinical settings and to help the persons seeking care live safer, healthier lives by preventing and treating STDs and related complications.

Abstract
BACKGROUND Southern non-Hispanic black persons are disproportionately represented in the HIV epidemic. Those previously diagnosed as having syphilis are at significant risk to become HIV infected within 36 months. Effective prevention strategies such as preexposure prophylaxis should be offered to those at highest risk to maximize prevention efforts. METHODS HIV-negative persons diagnosed as having primary or secondary (P&S) syphilis during 1998-2014 were matched with incident HIV cases diagnosed during 1998-2016 in Shelby County Tennessee. Person-year HIV incidence rate, Kaplan-Meier survival estimates, and Cox proportional regression model analyses were performed to explore predicting risk factors and quantifying risk factors associated with HIV-free survival time frames. RESULTS Among 2032 HIV-negative non-Hispanic black Shelby County residents diagnosed as having P&S syphilis, 139 (6.8%) were subsequently diagnosed as having HIV infection. Men who have sex with men (MSM) experienced the highest incidence of HIV diagnosis rate (4.98 per 100 person-years, 95% confidence interval, 4.76-5.2). Being male, MSM, younger than 30 years, or coinfected with gonorrhea increased risk of HIV acquisition 2.32, 11.80, 1.67, and 2.44 times, respectively, compared with being female, heterosexual men, 30+ years old, or not infected with other sexually transmitted infections. CONCLUSIONS Among our population diagnosed as having P&S syphilis, 1 in 6 MSM and 1 in 16 persons coinfected with gonorrhea were subsequently diagnosed as having HIV during 36 months of follow-up. These findings have implications for HIV screening and recruitment as priority preexposure prophylaxis candidates.

Abstract
Among men who have sex with men (MSM), those with a diagnosis of syphilis or other rectal sexually transmitted infections (STIs) are at a higher risk for human immunodeficiency virus acquisition, which is concerning given the large increase in recently reported syphilis cases in the United States. We have developed the first nonhuman primate model for rectally transmitted syphilis by exposing simian/human immunodeficiency virus-infected and naive rhesus macaques to Treponema pallidum in the rectum. All animals showed mucosal lesions, systemic dissemination, and seroconversion (treponemal antibodies). This model would be valuable for studying the manifestations of and interventions for T. pallidum infection, with and without human immunodeficiency virus coinfection.

Anal Ureaplasma spp. positivity among HIV positive men who have sex with men may be associated with high-risk-type HPV infections. Int J Infect Dis 2019; 84:75-79. [PMID: 31054966 DOI: 10.1016/j.ijid.2019.04.025] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2019] [Revised: 03/12/2019] [Accepted: 04/24/2019] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVE HIV positive individuals, particularly men having sex with men (MSM), are at increased risk of sexually transmitted infections (STIs) at genital and extra-genital sites. Data on anorectal Ureaplasma infections are lacking. The aim of our study was to characterize anal Ureaplasma positivity among a cohort of HIV positive MSM and evaluate possible association with papillomavirus infection at the same site. METHODS Anal swab samples, collected as part of routine screening for Chlamydia trachomatis and Neisseria gonorrhea, were additionally tested for HPV genotypes as well as for Ureaplasma and Mycoplasma using nucleic acid amplification method. RESULTS Out of a total of 222 study participants, 195 (89%, 95% CI (84.9-93.2)) were positive for HPV, approximately three quarter being high-risk genotypes. Forty three individuals (19.4%, 95% CI (14.4-24.3)) harbored Ureaplasma spp. Infection with high-risk HPV types was significantly associated with co-presence of Ureaplasma with an odds ratio (95% confidence-interval) of 2.59 (1.03-6.54), P = 0.04. CONCLUSION Besides a high predominance of HPV infection, asymptomatic HIV positive MSM had a high prevalence of anal Ureaplasma positivity. Concomitant infections with high-risk HPV genotypes were common and statistically significant. The role of this co-existence as a potential risk factor for anal carcinogenesis needs further elucidation.

Abstract
BACKGROUND Chlamydia trachomatis and Neisseria gonorrhoeae are the most commonly reported sexually transmitted infections in Canada. Existing national guidance on screening for these infections was not based on a systematic review, and recommendations as well as implementation considerations (e.g., population groups, testing and case management) should be explicit and reflect the quality of evidence. The aim of this systematic review is to synthesize research on screening for these infections in sexually active individuals within primary care. We will also review evidence on how people weigh the relative importance of the potential outcomes from screening, rated as most important by the Canadian Task Force on Preventive Health Care (CTFPHC) with input from patients and stakeholders. METHODS We have developed a peer-reviewed strategy to comprehensively search MEDLINE, Embase, Cochrane Library, CINAHL, and PsycINFO for English and French literature published 1996 onwards. We will also search trial registries and conference proceedings, and mine references lists. Screening, study selection, risk of bias assessments, and quality of findings across studies (for each outcome) will be independently undertaken by two reviewers with consensus for final decisions. Data extraction will be conducted by one reviewer and checked by another for accuracy and completeness. The CTFPHC and content experts will provide input for decisions on study design (i.e., when and whether to include uncontrolled studies for screening effectiveness) and for interpretation of the findings. DISCUSSION The results section of the review will include a description of all studies, results of all analyses, including planned subgroup and sensitivity analyses, and evidence profiles and summary of findings tables incorporating assessment based on Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods to communicate our confidence in the estimates of effect. We will compare our findings to others and discuss limitations of the review and available literature. The findings will be used by the CTFPHC-supplemented by consultations with patients and stakeholders and from other sources on issues of feasibility, acceptability, costs/resources, and equity-to inform recommendations on screening to support primary health care providers in delivering preventive care.

Gay Circuit Parties in Barcelona and Their Impact on Gonorrhea Incidence. ARCHIVES OF SEXUAL BEHAVIOR 2018; 47:2027-2034.

Abstract
This study explored the role of circuit parties on the incidence of gonorrhea among men who have sex with men (MSM) in Barcelona (Spain). Specifically, it aimed to detect cyclic peaks in the number of reported diagnoses of gonorrhea after gay circuit parties. We analyzed monthly cases of gonorrhea reported from January 2007 through December 2016 after the main annual gay circuit parties in Barcelona. We used the integer autoregressive model for time series with discrete values. The performance of the model was tested in heterosexual men and women, in whom the circuit parties could be expected to have no impact. A sensitivity analysis was conducted, changing post-event diagnosis windows to 1 week later/1 week before. In the study period, a total of 4182 of gonorrhea cases were detected, of which 74.8% (n = 2181) occurred in men who identified themselves as MSM. The average annual increase in gonorrhea cases reported among MSM was 32.57%. In an independent analysis of each gay circuit party, cases increased significantly in two of them. The results were also similar for same-sex practices among men only. On controlling for the increasing trend over the study period and the seasonal effect, an average of 1.16 gonorrhea cases in MSM (95% CI: 0.68, 1.64) were attributable to the celebration of one of the gay circuit parties considered. During the expected outbreak, an average of 13 gonorrhea cases were detected and between 5 and 13% were attributable to one of the circuit parties. In view of these findings, participants should consider seeking advice from their healthcare provider and practice safer sex using condoms to prevent sexually transmitted infections. Local public health services should be reinforced to ensure care for participants during and after gay circuit parties. More research is needed to design and implement preventive programs.

Abstract
INTRODUCTION Globally, prosecutions for non-disclosure, exposure or transmission of HIV frequently relate to sexual activity, biting, or spitting. This includes instances in which no harm was intended, HIV transmission did not occur, and HIV transmission was extremely unlikely or not possible. This suggests prosecutions are not always guided by the best available scientific and medical evidence. DISCUSSION Twenty scientists from regions across the world developed this Expert Consensus Statement to address the use of HIV science by the criminal justice system. A detailed analysis of the best available scientific and medical research data on HIV transmission, treatment effectiveness and forensic phylogenetic evidence was performed and described so it may be better understood in criminal law contexts. Description of the possibility of HIV transmission was limited to acts most often at issue in criminal cases. The possibility of HIV transmission during a single, specific act was positioned along a continuum of risk, noting that the possibility of HIV transmission varies according to a range of intersecting factors including viral load, condom use, and other risk reduction practices. Current evidence suggests the possibility of HIV transmission during a single episode of sex, biting or spitting ranges from no possibility to low possibility. Further research considered the positive health impact of modern antiretroviral therapies that have improved the life expectancy of most people living with HIV to a point similar to their HIV-negative counterparts, transforming HIV infection into a chronic, manageable health condition. Lastly, consideration of the use of scientific evidence in court found that phylogenetic analysis alone cannot prove beyond reasonable doubt that one person infected another although it can be used to exonerate a defendant. CONCLUSIONS The application of up-to-date scientific evidence in criminal cases has the potential to limit unjust prosecutions and convictions. The authors recommend that caution be exercised when considering prosecution, and encourage governments and those working in legal and judicial systems to pay close attention to the significant advances in HIV science that have occurred over the last three decades to ensure current scientific knowledge informs application of the law in cases related to HIV.

Abstract
BACKGROUND Syphilis in pregnancy is an under-recognized public health problem, especially in sub-Saharan Africa which accounts for over 60% of the global burden of syphilis. If left untreated, more than half of maternal syphilis cases will result in adverse pregnancy outcomes including stillbirth and fetal loss, neonatal death, prematurity or low birth weight, and neonatal infections. Achieving universal coverage of antenatal syphilis screening and treatment has been the focus of the global campaign for the elimination of mother-to-child transmission of syphilis. However, little is known about the availability of antenatal syphilis screening and treatment across sub-Saharan Africa. The objective of this study was to estimate the 'likelihood of appropriate care' for antenatal syphilis screening and treatment by analyzing health facility surveys and household surveys conducted from 2010 to 2015 in 12 sub-Saharan African countries. METHODS In this secondary data analysis, we linked indicators of health facility readiness to provide antenatal syphilis detection and treatment from Service Provision Assessments (SPAs) and Service Availability and Readiness Assessments (SARAs) to indicators of ANC use from the Demographic and Health Surveys (DHS) to compute estimates of the 'likelihood of appropriate care'. RESULTS Based on data from 5,593 health facilities that reported offering antenatal care (ANC) services, the availability of syphilis detection and treatment in ANC facilities ranged from 2% to 83%. The availability of syphilis detection and treatment was substantially lower in ANC facilities in West Africa compared to the other sub-regions. Levels of ANC attendance were high (median 94.9%), but only 27% of ANC attendees initiated care at less than 4 months gestation. We estimated that about one in twelve pregnant women received ANC early (<4 months) at a facility ready to provide syphilis detection and treatment (median 8%, range 7-32%). The largest implementation bottleneck identified was low health facility readiness, followed by timeliness of the first ANC visit. CONCLUSIONS While access was fairly high, the low levels of likelihood of antenatal syphilis detection and treatment identified reinforce the need to improve the availability of syphilis rapid diagnostic tests and treatment and the timeliness of antenatal care-seeking across sub-Saharan Africa.

Abstract
OBJECTIVES A new molecular test for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) (GeneXpert CT/NG) has been demonstrated to be as accurate as conventional nucleic acid amplification tests (NAAT), but performance has not been evaluated in routine primary care, performed at the point of care by clinicians. We aimed to examine its diagnostic performance when used by clinicians in remote community health services in Australia with high prevalences of CT and NG infection. The trial was registered with the Australian and New Zealand Clinical Trials Registry (#12613000808741) METHODS: At 12 health services, training was provided to 99 clinicians in the use of the GeneXpert CT/NG assay who tested specimens from all patients undergoing STI screening. Specimens were also sent in parallel for conventional laboratory-based NAATs and the concordance of results was evaluated. RESULTS Clinicians conducted 2486 tests: CT concordance was 99.4% (95% CI 99.1 to 99.7) with a positive concordance of 98.6% (95% CI 95.9 to 99.7) and negative concordance of 99.5% (95% CI 99.1 to 99.8); NG concordance was 99.9% (95% CI 99.7 to 100.0) with a positive concordance of 100.0% (95% CI 97.5 to 100.0) and negative concordance of 99.9% (95% CI 99.7 to 100.0). CONCLUSIONS In this first study reporting routine point-of-care use of GeneXpert CT/NG by primary care clinicians, we found excellent concordance with conventional NAATs. The use of the GeneXpert CT/NG at the point of care could potentially transform management and control of these infections in many endemic settings, including low/middle-income countries.

Abstract
Human immunodeficiency virus-acquired immunodeficiency syndrome (HIV/AIDS) remains a global health problem. Current therapeutics specifically target the viral pathogen at various stages of its life cycle, although complex interactions between HIV and other pathogenic organisms are evident. Targeting HIV and concomitant infectious pathogens simultaneously, both by therapeutic regimens and in prevention strategies, would help contain the AIDS pandemic. Lectins, a ubiquitous group of proteins that specifically bind glycosylated molecules, are interesting compounds that could be used for this purpose, with demonstrated anti-HIV properties. In addition, potential coinfecting pathogens, including other enveloped viruses, bacteria, yeasts and fungi, and protozoa, display sugar-coated macromolecules on their surfaces, making them potential targets of lectins. This review summarizes the currently available findings suggesting that lectins should be further developed to simultaneously fight the AIDS pandemic and concomitant infections in HIV infected individuals.

US Public Sexually Transmitted Disease Clinical Services in an Era of Declining Public Health Funding: 2013-14. Sex Transm Dis 2018; 44:505-509.

Abstract
BACKGROUND We examined the infrastructure for US public sexually transmitted disease (STD) clinical services. METHODS In 2013 to 2014, we surveyed 331 of 1225 local health departments (LHDs) who either reported providing STD testing/treatment in the 2010 National Profile of Local Health Departments survey or were the 50 local areas with the highest STD cases or rates. The sample was stratified by jurisdiction population size. We examined the primary referral clinics for STDs, the services offered and the impact of budget cuts (limited to government funding only). Data were analyzed using SAS, and analyses were weighted for nonresponse. RESULTS Twenty-two percent of LHDs cited a specialty STD clinic as their primary referral for STD services; this increased to 53.5% of LHDs when combination STD-family planning clinics were included. The majority of LHDs (62.8%) referred to clinics providing same-day services. Sexually transmitted disease clinics more frequently offered extragenital testing for chlamydia and/or gonorrhea (74.7%) and gonorrhea culture (68.5%) than other clinics (52.9%, 46.2%, respectively; P < 0.05). The majority of LHDs (61.5%) reported recent budget cuts. Of those with decreased budgets, the most common impacts were fewer clinic hours (42.8%; 95% confidence interval [CI], 24.4-61.2), reduced routine screening (40.2%; 95% CI, 21.7-58.8) and reductions in partner services (42.1%; 95% CI, 23.6-60.7). One quarter of those with reduced STD budgets increased fees or copays for clients. CONCLUSIONS Findings demonstrate gaps and reductions in US public STD services including clinical services that play an important role in reducing disease transmission. Furthermore, STD clinics tended to offer more specialized STD services than other public clinics.

Abstract
Access to effective affordable contraception is critical for individual and public health. A wide range of hormonal contraceptives (HCs), which differ in composition, concentration of the progestin component, frequency of dosage, and method of administration, is currently available globally. However, the options are rather limited in settings with restricted economic resources that frequently overlap with areas of high HIV-1 prevalence. The predominant contraceptive used in sub-Saharan Africa is the progestin-only three-monthly injectable depot medroxyprogesterone acetate. Determination of whether HCs affect HIV-1 acquisition has been hampered by behavioral differences potentially confounding clinical observational data. Meta-analysis of these studies shows a significant association between depot medroxyprogesterone acetate use and increased risk of HIV-1 acquisition, raising important concerns. No association was found for combined oral contraceptives containing levonorgestrel, nor for the two-monthly injectable contraceptive norethisterone enanthate, although data for norethisterone enanthate are limited. Susceptibility to HIV-1 and other sexually transmitted infections may, however, be dependent on the type of progestin present in the formulation. Several underlying biological mechanisms that may mediate the effect of HCs on HIV-1 and other sexually transmitted infection acquisition have been identified in clinical, animal, and ex vivo studies. A substantial gap exists in the translation of basic research into clinical practice and public health policy. To bridge this gap, we review the current knowledge of underlying mechanisms and biological effects of commonly used progestins. The review sheds light on issues critical for an informed choice of progestins for the identification of safe, effective, acceptable, and affordable contraceptive methods.

Cost-Effectiveness of Dual Antimicrobial Therapy for Gonococcal Infections Among Men Who Have Sex With Men in the Netherlands. Sex Transm Dis 2017; 43:542-8.

Abstract
BACKGROUND In response to the rising threat of resistance to first-line antibiotics for gonorrhea, international guidelines recommend dual antimicrobial therapy. However, some countries continue to recommend monotherapy. We assess the cost-effectiveness of dual therapy with ceftriaxone and azithromycin compared with monotherapy with ceftriaxone, for control of gonorrhea among men who have sex with men in the Netherlands. METHODS We developed a transmission model and calculated the numbers of new gonorrhea infections, consultations at health care specialists, tests, and antibiotic doses. With these numbers, we calculated costs and quality-adjusted life-years (QALY) with each treatment; and the incremental cost-effectiveness ratio (ICER) of dual therapy compared to monotherapy. The impact of gonorrhea on human immunodeficiency virus transmission was not included in the model. RESULTS In the absence of initial resistance, dual therapy can delay the spread of ceftriaxone resistance by at least 15 years, compared to monotherapy. In the beginning, when there is no resistance, dual therapy results in high additional costs, without any QALY gains. When resistance spreads over time, the additional costs of dual therapy decline, the gained QALYs increase, the ICER drops off and, after 50 years, falls below &OV0556;20,000 per QALY gained. If azithromycin resistance is initially prevalent, resistance to the first-line treatment rises almost equally fast with both treatment strategies and the ICER remains extremely high. CONCLUSIONS Compared with ceftriaxone monotherapy, dual therapy with ceftriaxone and azithromycin can considerably delay the spread of ceftriaxone resistance, but may only be cost-effective in the long run and in the absence of initial resistance.

Abstract
We compared the analytical and clinical performance of cobas® CT/NG for use on the Cobas® 6800/8800 Systems with the Cobas® 4800 CT/NG Test from urogenital and extragenital specimens in over 12,000 specimens from both male and female subjects in Germany and the United States. The analytical sensitivity was ≤40 EB/ml for Chlamydia trachomatis (CT) and ≤1 CFU/ml for Neisseria gonorrhoeae (NG). Using clinical specimens, the overall percent agreement with the Cobas® 4800 CT/NG Test was >98.5%. Across urogenital specimens, there were 93 discrepant specimens; 76 (93.8%) of 81 CT discrepant specimens were 6800+/4800– and 10 (83.3%) of 12 NG discrepant specimens were 6800+/4800–. Sequencing verified CT results for 45 (61.6%) of 73 samples positive by 6800 and 1 (20%) of 5 positive by 4800. Similarly, 7 (70.0%) of 10 NG samples positive by 6800 and 1 of 2 positive by 4800 were confirmed by sequencing. Among discrepant extragenital specimens (all 6800+/4800–), 7 (50%) of 14 oropharyngeal and 23 (76.7%) of 30 anorectal CT discordant samples were confirmed as CT positive by sequencing; all 8 anorectal and 20 (90.9%) of 22 oropharyngeal NG discordant results were also confirmed as NG positive. In conclusion, Cobas® CT/NG for use on the Cobas® 6800/8800 Systems provides high-throughput automated solutions for sexually transmitted infection (STI) screening programs.

Abstract
INTRODUCTION Chlamydia, gonorrhea and trichomonas are the most common curable STI. improved access to testing could reduce infection rates and prevent sequelae. nucleic acid amplification tests are the recommend class of diagnostic assay for these infections which are often asymptomatic. Areas covered: A description of the BD MAX™ System (MAX) and the BD MAX CT/GC/TV assay is provided along with data from a large US clinical trial. The capacity of the system for other tests and for lab developed assays is also described. Expert commentary: The CT/GC/TV assay on the MAX is a triplex PCR assay suitable for use with female urine and vaginal or endocervical swab samples. Male urine can be tested by ordering the CT/GC results but has not yet been evaluated for trichomonas. The assay performance characteristics are similar to those of assays run on high-throughput platforms with sensitivity ≥91.5% and specificity ≥98.6% for all analytes. Screening with the CT/GC/TV assay can be combined with testing for vaginitis which would provide a greater depth of coverage for common co-infections. The throughput is moderate (1-48 samples per 8-hour shift) but the menu includes assays beyond STI pathogens making this a suitable platform for moderate volume laboratories.

Abstract
INTRODUCTION Criminal cases involving human immunodeficiency virus transmission or exposure require that courts correctly comprehend the rapidly evolving science of HIV transmission and the impact of an HIV diagnosis. This consensus statement, written by leading HIV clinicians and scientists, provides current scientific evidence to facilitate just outcomes in Australian criminal cases involving HIV.Main recommendations: Caution should be exercised when considering charges or prosecutions regarding HIV transmission or exposure because:Scientific evidence shows that the risk of HIV transmission during sex between partners of different HIV serostatus can be low, negligible or too low to quantify, even when the HIV-positive partner is not taking effective antiretroviral therapy, depending on the nature of the sexual act, the viral load of the partner with HIV, and whether a condom or pre-exposure prophylaxis is employed to reduce risk.The use of phylogenetic analysis in cases of suspected HIV transmission requires careful consideration of its limited probative value as evidence of causation of HIV infection, although such an approach may provide valuable information, particularly in relation to excluding HIV transmission between individuals.Most people recently infected with HIV are able to commence simple treatment providing them a normal and healthy life expectancy, largely comparable with their HIV-negative peers. Among people who have been diagnosed and are receiving treatment, HIV is rarely life threatening. People with HIV can conceive children with negligible risk to their partner and low risk to their child.Changes in management as result of the consensus statement: Given the limited risk of HIV transmission per sexual act and the limited long term harms experienced by most people recently diagnosed with HIV, appropriate care should be taken before HIV prosecutions are pursued. Careful attention should be paid to the best scientific evidence on HIV risk and harms, with consideration given to alternatives to prosecution, including public health management.

Abstract
OBJECTIVES We used area-level indicators of poverty to describe economic disparities in the incidence rate of infectious syphilis in Massachusetts to (1) determine whether methods developed in earlier AIDS analyses in Massachusetts could be applied to syphilis and (2) characterize syphilis trends during a time of increased rates of syphilis incidence. METHODS Using census tract data and population counts from the US Census Bureau and Massachusetts data on syphilis, we analyzed the incidence rate of syphilis infection from 2001 to 2013 by the poverty level of the census tract in which people with syphilis resided, stratified by age, sex, and race/ethnicity. RESULTS The syphilis incidence rate increased in all census tract groups in Massachusetts from 2001 to 2013, and disparities in incidence rates by area poverty level persisted over time. The overall incidence rate of syphilis increased 6.9-fold from 2001 to 2013 in all census tract poverty-level groupings (from 1.5 to 10.3 per 100 000 population), but the rise in rate was especially high in the poorest census tracts (from 5.6 to 31.0 per 100 000 population) and among men (from 2.2 to 19.4 per 100 000 population). The highest syphilis incidence rate was among non-Hispanic black people. The largest changes in incidence rate occurred after 2010. One region had a disproportionate increase in incidence rates and a disproportionate impact on the statewide trend. CONCLUSIONS Census tract poverty analyses can inform the targeting of interventions that make progress toward reducing disparities in rates of syphilis incidence possible.

Abstract
OBJECTIVE To examine how relational qualities, including commitment to a sexual partner, are associated with condom use among young heterosexual adults at increased risk for sexually transmitted infections. Guided by the investment model of commitment processes, we hypothesized that sexual partner commitment is a function of satisfaction with, alternatives to, and investments in the relationship. Commitment to a sexual partner is, in turn, associated with reduced perceptions of vulnerability to sexually transmitted infection acquisition, which results in lowered condom use intentions and use. METHOD We tested the hypothesized model using data from the Project on Partner Dynamics (POPD), a 4-wave, 1-year longitudinal study featuring a Time 1 sample of 538 African American, Hispanic, and White young adult from East Los Angeles, California, who provided data on all their sexual relationships over the year. RESULTS Findings from hierarchical path models supported the hypotheses, with relational qualities significantly linked to condom use via commitment, perceived vulnerability to harm from partner and intentions to use. CONCLUSION These findings have implications for improving the health of high-risk individuals, including suggesting the importance of raising awareness of relational qualities that may give rise to unsafe sexual practices.

Abstract
Genital infection with Chlamydia trachomatis, a gram-negative obligate intracellular bacterium, is the most common bacterial sexually transmitted infection globally. Ascension of chlamydial infection to the female upper genital tract can cause acute pelvic inflammatory disease, tubal factor infertility, ectopic pregnancy, and chronic pelvic pain. Shortcomings of current chlamydia control strategies, especially for low- and middle-income countries, highlight the need for an effective vaccine. Evidence from animal models, human epidemiological studies, and early trachoma vaccine trials suggest that a C. trachomatis vaccine is feasible. Vaccine development for genital chlamydial infection has been in the preclinical phase of testing for many years, but the first Phase I trials of chlamydial vaccine candidates are underway, and scientific advances hold promise for additional candidates to enter clinical evaluation in the coming years. We describe the clinical and public health need for a C. trachomatis vaccine, provide an overview of Chlamydia vaccine development efforts, and summarize current vaccine candidates in the development pipeline.

Abstract
Background Late presentation of human immunodeficiency virus (HIV) is associated with heterosexual transmission, particularly among heterosexual men in Asia. Although data on HIV/sexually transmitted infection (STI) testing behaviour is increasing, information is still lacking among heterosexual men who receive far lesser attention and are generally invisible in HIV/ STI prevention, particularly in the Asian urban setting. The aim of this study was to assess the prevalence of HIV/STI testing among heterosexual men patronising entertainment establishments (EEs) who engaged in casual or paid sex in Singapore, and the factors associated with this behaviour. Methods This was a cross-sectional survey involving 604 participants using time location sampling between March and May 2015. For multivariable analysis, we used a mixed effects Poisson regression model with backward stepwise approach to account for clustering by venue and to obtain the adjusted prevalence ratio (aPR) for the association of various factors with HIV/STI testing. Results Among 604 at-risk participants, only 163 (27.0%) had gone for HIV or STI testing in the past 6 months. Of this, 83.4% of them specifically underwent HIV testing. In multivariable analysis, HIV/STI testing increased with being non-Chinese (aPR 1.50; 95% CI: 1.08–2.06), having engaged in anal sex with casual or paid partner in the past 6 months (aPR 1.80; 95% CI: 1.27–2.57), number of partners in the past 6 months (aPR 1.03; 95% CI: 1.01–1.05) and HIV knowledge score (aPR 1.11; 95% CI: 1.05–1.16). Among those who reported non-consistent condom use with casual or paid partner, almost half of them (47.9%) perceived that they were at low risk for HIV/STI. Sigmatisation and discrimination was another common barrier for non-testing. Conclusions Despite being at risk of HIV/STI, the low prevalence of testing coupled with a high prevalence of risky sexual behaviour among this group of heterosexual men in Singapore calls for a need for HIV/STI prevention interventions in the EE setting. Other than promoting testing and safer sex, the interventions should address the discordance between perceived risk and actual sexual behaviour, in addition to the stigma and discrimination associated with testing for this group.

Abstract
BACKGROUND The asymptomatic nature and suboptimal screening rates of sexually transmitted diseases (STD) call for implementation of successful interventions to improve screening in community-based clinic settings with attention to cost and resources. METHODS We used MEDLINE to systematically review comparative analyses of interventions to improve STD (chlamydia, gonorrhea, or syphilis) screening or rescreening in clinic-based settings that were published between January 2000 and January 2014. Absolute differences in the percent of the target population screened between comparison groups or relative percent increase in the number of tests or patients tested were used to score the interventions as highly effective (>20% increase) or moderately effective (5%-19% increase) in improving screening. Published cost of the interventions was described where available and, when not available, was estimated. RESULTS Of the 4566 citations reviewed, 38 articles describing 42 interventions met the inclusion criteria. Of the 42 interventions, 16 (38.1%) were categorized as highly effective and 14 (33.3%) as moderately effective. Effective low-cost interventions (<$1000) included the strategic placement of specimen collection materials or automatic collection of STD specimens as part of a routine visit (7 highly effective and 1 moderately effective) and the use of electronic health records (EHRs; 3 highly effective and 4 moderately effective). Patient reminders for screening or rescreening (via text, telephone, and postcards) were highly effective (3) or moderately effective (2) and low or moderate cost (<$1001-10,000). Interventions with dedicated clinic staff to improve STD screening were highly effective (2) or moderately effective in improving STD screening (1) but high-cost ($10,001-$100,000). CONCLUSIONS Successful interventions include changing clinic flow to routinely collect specimens for testing, using EHR screening reminders, and reminding patients to get screened or rescreened. These strategies can be tailored to different clinic settings to improve screening at a low cost.

Abstract
Despite the availability of inexpensive antimicrobial treatment, syphilis remains prevalent worldwide, affecting millions of individuals. Furthermore, syphilis infection is suspected of increasing both susceptibility to, and tendency to transmit, HIV. Development of a syphilis vaccine would be a potentially promising step towards control, but the value of dedicating resources to vaccine development should be evaluated in the context of the anticipated benefits. Here, we use a detailed mathematical model to explore the potential impact of rolling out a hypothetical syphilis vaccine on morbidity from both syphilis and HIV and compare it to the impact of expanded ‘screen and treat’ programmes using existing treatments. Our results suggest that an efficacious vaccine has the potential to sharply reduce syphilis prevalence under a wide range of scenarios, while expanded treatment interventions are likely to be substantially less effective. Our modelled interventions in our simulated study populations are expected to have little effect on HIV, and in some scenarios lead to small increases in HIV incidence, suggesting that interventions against syphilis should be accompanied with interventions against other sexually transmitted infections to prevent the possibility that lower morbidity or lower perceived risk from syphilis could lead to increases in other sexually transmitted diseases.
