An Evaluation of the Performance, Patient Acceptability and Feasibility of a Point-of-Care HIV-Syphilis Assay in an Urban Emergency Department.

BACKGROUND: Point-of-care (POC) tests for sexually transmitted infections (STIs) permit delivery of results during the patient's emergency department (ED) encounter. We evaluated performance, patient acceptability, and feasibility of a new duplex POC test, Chembio DPP® HIV-Syphilis Assay in an urban ED setting. METHODS: Convenience sampling approach prioritizing those considered at increased risk for an STI and/or with a history of HIV. For the performance evaluation, participants were tested for HIV/syphilis with the Chembio POC assay, and the reference laboratory tests; sensitivity and specificity were determined. For the patient acceptability evaluation, participants completed pre- and post-user surveys. For the feasibility evaluation, ED clinical technicians completed a survey evaluating their perceptions regarding feasibility of use of this POC test. RESULTS: 327 patients were consented and enrolled. The diagnostic sensitivity and specificity of the Chembio POC assay for HIV was 96.5% (95% CI: 90.1%, 99.3%) and 99.6% (95% CI: 97.7%, 100.0%), respectively, and for syphilis was 93.9% (95% CI: 85.0%, 98.3%) and 99.6% (95% CI: 97.9%, 100.0%), respectively. Regarding patient acceptability: 87% trusted the result; and 93% reported they were more likely to seek treatment if they received a positive STI test result in the ED rather than after the ED visit. Regarding feasibility: 90% of the technicians reported they would recommend using the test in EDs. CONCLUSIONS: The Chembio DPP® HIV-Syphilis POC assay had excellent performance characteristics when evaluated in an ED population, as well as high perceived acceptability from patients, and feasibility for ED use from clinical technicians. The test may have utility for HIV-syphilis screening among high-risk ED patients.

Validation of a New Duplex Real-Time Polymerase Chain Reaction for Chlamydia trachomatis DNA Detection in Ocular Swab Samples.

Trachoma is the world-leading infectious cause of preventable blindness and is caused by the bacteria Chlamydia trachomatis. In developing countries, diagnosis is usually based on clinical evaluation. Serological-based tests are cheaper than molecular-based ones, but the latter are more sensitive and specific. The present study developed a new duplex qPCR which concomitantly detects the C. trachomatis cryptic plasmid and the human 18S rRNA gene, with an LOD95% for C. trachomatis DNA of 13.04 genome equivalents per reaction. The new qPCR was tested using 50 samples from an endemic area and 12 from a non-endemic area that were previously characterized using direct immunofluorescence assay (DFA) and clinical evaluation. Among the 50 endemic samples, 3 were found to be positive by clinical evaluation (6%), 18 were found to be positive by DFA (36%), and 48 were found to be positive by qPCR (96%). Next, the new duplex qPCR was validated using 50 samples previously characterized by qPCR. Validation was carried out on a benchtop instrument (ABI7500) or on a portable point-of-care instrument (Q3-Plus), showing 95% specificity and 100% sensitivity. The ubiquitous presence of C. trachomatis DNA in samples from the endemic region confirms that constant monitoring is of paramount importance for the effective measurement of the elimination of trachoma. The newly developed duplex qPCR presented in this study, along with its validation in a portable qPCR system, constitutes important tools toward achieving this goal.

Undermining the Translational Potential of Clinical Research with Adolescents and Young Adults: Differential Enrollment in Randomized Clinical Trials During COVID-19.

BACKGROUND: COVID-19 stay-at-home orders and research restrictions halted recruitment and follow-up of clinical research patients. While clinical research has resumed, it is an open question whether research participation has returned to levels similar to those before COVID-19. METHODS: We utilized data from the TECH-PN (NCT# NCT03828994) study, a single-center RCT enrolling 13-25-year-olds with mild-moderate pelvic inflammatory disease (PID) receiving ambulatory care. We examined enrollment patterns before COVID-19 and during/after COVID-19 among those assessed for eligibility by estimating the average rate of recruitment visits for each period. We focused on this monthly rate by pandemic status, the length of stay (LOS) by pandemic status, as well as the relationship between the LOS and patient demographics. Descriptive analyses were conducted, including Student's t-test to compare rates between time periods and a Chi-square test to compare the proportion refusing enrollment. RESULTS: The monthly enrollment rate during/post-pandemic was significantly lower than before COVID-19 (4.8 per month compared to 7.4 per month, p < 0.001). However, eligible participants' age, race, and insurance type were similar pre- and during/post-pandemic. Among eligible patients, LOS for receiving PID care was slightly increased, from a median of 5.4 hours to 6.4 hours (p = 0.650), and the rate of refusal to participate among those eligible was similar (23% versus 27%, p = 0.362). There was a similar number of ineligible patients due to inpatient admissions during both periods. CONCLUSION: COVID-19 pandemic restrictions negatively impacted recruitment into this RCT. Enrollment differences may reflect ongoing perceptions of restrictions in care access or a hesitancy to use health services. More research is needed to stabilize access to ambulatory STI/PID care and access to clinical trials.

Improving Access to Care Through Youth-Focused Virtual Sexual Health Navigation.

PURPOSE: Gender and sexually diverse adolescents and young adults in Baltimore City, Maryland, are disproportionately impacted by HIV. The Virtual and Online Integrated Sexual Health Services for Youth program is a health navigation program which combines virtual sexual health service delivery and health navigation to link youth at risk for HIV acquisition to HIV testing/prevention and sexual healthcare services. METHODS: Youth between 13 and 26 years old and residing in the Baltimore area were eligible to participate in the program. Demographic and engagement data from 238 youth (average age 21.4, SD = 2.5) who requested navigation were collected and recorded in a Health Insurance Portability and Accountability Act (HIPAA)-secure medical database and examined for associations between demographics, referral source, and the number of navigational services to which they were linked. Focused populations were defined as residents of high HIV prevalence zip codes who identify as sexual and gender diverse youth. RESULTS: Receipt of navigational services was significantly associated with self-identifying as sexually diverse. A multivariate regression revealed a significant association between the count of navigational services a youth was linked to and recording one's sexual orientation, identifying as a cisgender male, and residing in a high HIV-prevalence zip code. DISCUSSION: Virtual health navigation has the potential to engage priority populations, including sexual and gender diverse youth. By refining linkage and identification approaches to health navigation, future outreach attempts can be tailored to support vulnerable communities, with the potential to improve sexual healthcare access.

Age Differences in the Associations Between Incarceration and Subsequent Substance Use, Sexual Risk-Taking, and Incident STI Among Black Sexual Minority Men and Black Transgender Women in the HIV Prevention Trials 061 Cohort.

Incarceration can lead to different risk behaviors often due to increased distress and disruption of social networks. It is not well known, however, how these associations may differ by age. In this study, we measure age differences in longitudinal associations between incarceration and substance use, sex risk, and sexually transmitted infection (STI) among Black sexual minority men and Black transgender women (BSMM/BTW). We recruited BSMM/BTW from 2009 to 2011 that were part of the HIV Prevention Trials Network 061 study. We compared those less than 30 years old (n = 375) to those 30 years old or greater (n = 794) examining substance use, sex risk, and STI infection stratified by age. Logistic regression with inverse probability weighting was used for the statistical analysis. Approximately 59% of the sample reported incarceration history. In adjusted analysis, incarceration was more strongly associated with alcohol use and stimulant use among older individuals as was sexual risk behaviors including buying and selling sex. Concurrent partnerships were associated with the younger age groups. STI incidence was associated with younger individuals while associations with HIV infection were similar for the two age groups. Understanding differences in substance use and STI risk among age cohorts is imperative to the design and implementation of re-entry programs. Younger BSMM/BTW participating in re-entry support programs may benefit in particular from HIV/STI prevention and care efforts, while post-release substance abuse treatment and harm reduction programs should target older individuals with continued substance abuse.

Self-collected samples as an additional option for STI testing in low-resource settings: a qualitative study of acceptability among adults in Rakai, Uganda.

INTRODUCTION: Self-collected samples (SCS) for sexually transmitted infection (STI) testing have been shown to be feasible and acceptable in high-resource settings. However, few studies have assessed the acceptability of SCS for STI testing in a general population in low-resource settings. This study explored the acceptability of SCS among adults in south-central Uganda. METHODS: Nested within the Rakai Community Cohort Study, we conducted semistructured interviews with 36 adults who SCS for STI testing. We analysed the data using an adapted version of the Framework Method. RESULTS: Overall, SCS was acceptable to both male and female participants, regardless of whether they reported recent STI symptoms. Perceived advantages of SCS over provider-collection included increased privacy and confidentiality, gentleness and efficiency. Disadvantages included the lack of provider involvement, fear of self-harm and the perception that SCS was unhygienic. Most participants preferred provider-collected samples to SCS. Nevertheless, almost all said they would recommend SCS and would do it again in the future. CONCLUSION: SCS are acceptable among adults in this low-resource setting and could be offered as an additional option to expand STI diagnostic services.

Heterogeneity in practitioner-reported barriers to use, cost considerations and priorities for point of care sexually transmitted infection tests on surveys across seven years.

BACKGROUND: Point of care diagnostic tests (POCTs) for sexually transmitted infections (STIs) have the potential to improve STI care worldwide. However, barriers to adoption, cost considerations and practitioner priorities may not be uniform globally and over time. We conducted two surveys, 7 years apart, among members of the International Union Against Sexually Transmitted Infections (IUSTI), and compare results here. METHODS: Surveys were given to members attending two IUSTI conferences in 2012 (Australia) and 2019 (Estonia). Descriptive analyses were performed and chi-square or Fisher's exact tests conducted. RESULTS: Amongst N = 190 participants in 2012 and N = 166 in 2019, 61% in 2012 and 77% in 2019 were from high-income countries (HICs). In 2012, 84% of respondents from low- and middle-income countries (LMICs) and 70% from HICs thought cost of test was more important than amount of reimbursement. Trends were similar in 2019. In 2012, unreliability was considered the most important barrier to POCT use by all groups, followed by being laboratory-driven and complexity. In 2019, time frame was considered most important, followed by unreliability and being laboratory-driven. In 2012, the top priority for POCT development among LMIC respondents was early HIV seroconversion (31%), versus chlamydia (57%) for HICs. In 2019, chlamydia remained top priority for HICs (40%), followed by early HIV seroconversion (19%) and gonorrhea (17%); top priorities for LMICs were chlamydia (26%), HPV (24%), and early HIV seroconversion (21%). CONCLUSIONS: Practitioner priorities for STI POCTs may be shifting. Cost may be critical to adoption in all settings. Larger studies are needed to verify findings.

Diversity of Anal HPV and Non-HPV Sexually Transmitted Infections and Concordance with Genital Infections in HIV-Infected and HIV-Uninfected Women in the Tapajós Region, Amazon, Brazil.

The aim of this study was to classify the diversity of anal HPV and non-HPV sexually transmitted infections (STIs) and compare the concordance between anal and genital infections in HIV-infected and uninfected women living in the Tapajós region, Amazon, Brazil. A cross-sectional study was performed with 112 HIV-uninfected and 41 HIV-infected nonindigenous women. Anal and cervical scrapings were collected and analyzed for HPV, Chlamydia trachomatis (CT), Neisseria gonorrheae (NG), Trichomonas vaginalis (TV), Mycoplasma genitalium (MG), and Human alphaherpesvirus 2 (HSV-2). The Kappa test evaluated the concordance between anal and genital infections. The overall prevalence of anal HPV infection was 31.3% in HIV-uninfected and 97.6% in HIV-infected women. The most frequent anal high-risk HPV (hrHPV) types were HPV18 and HPV16 in HIV-uninfected women and HPV51, HPV59, HPV31, and HPV58 in HIV-infected women. Anal HPV75 Betapapillomavirus was also identified. Anal non-HPV STIs were identified in 13.0% of all participants. The concordance analysis was fair for CT, MG, and HSV-2, almost perfect agreement for NG, moderate for HPV, and variable for the most frequent anal hrHPV types. Thus, a high prevalence of anal HPV infection with moderate and fair concordance between anal and genital HPV and non-HPV STIs was observed in our study.

Preferences for Rectal Sexually Transmitted Infection Sample Collection and Sexual Behaviors Among Adolescent and Young Adult Women Accessing Primary Care Services.

BACKGROUND: High prevalence of asymptomatic rectal chlamydia and gonorrhea among women is increasingly recognized. Screening is controversial because of lack of natural history data. Barriers to screening may include reluctance to discuss anal sex and collect rectal samples. This study describes the prevalence of sexual contact exposing adolescent and young adult women to extragenital sexually transmitted infections and acceptability of self-collection and clinician collection of rectal samples, preference for self- versus clinician-collected rectal samples, and preference for home or doctor's office for sample collection. METHODS: Participants were recruited from a primary care office and completed structured interviews assessing types of sexual contact and attitudes about rectal sampling. Differences were tested using χ2 and 2-sided Fisher exact test. RESULTS: Of 110 cisgender women (aged 14-22 years) enrolled, the average age was 18.4 years (SD, 1.7 years), 83% reported a history of extragenital contact, 22% reported history of receptive anal intercourse. A majority of participants reported self- and clinician-collected rectal samples to be acceptable (86% and 73%, respectively), with preferences for self-collection (71%) over clinician collection (29%, P < 0.001) and collection at the doctor's office (85%) over home (15%, P < 0.001). CONCLUSIONS: Adolescent and young adult (AYA) women engage in behaviors that increase the risk of rectal sexually transmitted infection (STI). Self- and clinician-collected rectal samples were acceptable. A majority of AYA women preferred to collect rectal samples in the doctor's office rather than at home. This may reduce adolescents' access to direct-to-consumer STI services. Offering in-clinic, self-collected rectal samples may improve uptake of rectal STI screening in adolescent girls.

Nearly half of adults with symptoms of sexually transmitted infections (STIs) did not seek clinical care: A population-based study of treatment-seeking behavior among adults in Rakai, Uganda.

Understanding treatment-seeking behavior is critical to the treatment and control of sexually transmitted infections (STIs), yet current data on STI treatment seeking in low-resource settings is rare. This population-based study aimed to describe STI treatment-seeking behavior and identify factors associated with seeking treatment at a clinic among adults with STI-related symptoms in rural Uganda. The STI prevalence study (STIPS) conducted a survey and STI testing among all consenting adults aged 18-49 in two communities in rural south-central Uganda. Of 1,825 participants, 962 individuals self-reported STI symptoms in the past six months; we present descriptive data on treatment seeking and STI prevalence among these individuals. We used multivariable Poisson regressions with robust variance to determine the sociodemographic and symptom-related factors independently associated with seeking STI treatment at a clinic and assessed the association with previous clinic treatment seeking and current STI diagnosis. Forty-three percent of adults who reported STI-related symptoms in the past six months said they did not seek any treatment. Among those who did, 58% sought treatment at a private clinic, 28% at a government clinic, 9% at a pharmacy/drug store, 3% at a traditional healer, 2% at a market/shop, and 5% at another location. Among both males and females, having multiple STI related symptoms was positively associated with clinic treatment seeking (males = PRR: 1.73, 95%CI: 1.36-2.21; females = PR: 1.41, 95%CI: 1.12-1.78). Approximately one-third of males and females who reported previously seeking clinic treatment for their symptoms were diagnosed with a curable STI at the time of the survey. In this setting, nearly half of adults with STI-related symptoms are not seeking clinical care and many who report having sought treatment for recent STI symptoms have curable STIs. Future studies should explore barriers to care-seeking and strategies to improve STI services.

A National, County-Level Evaluation of the Association Between COVID-19 and Sexually Transmitted Infections Within the United States in 2020.

BACKGROUND: Shifts in public health infrastructure to respond to one emerging health threat may have unanticipated consequences for preexisting diseases. Previous research evaluating the impact of COVID-19 on sexually transmitted infections (STIs) has been conducted nationally, with little exploration of the impact on a granular geospatial level. This ecological study seeks to quantify the association between COVID-19 cases or deaths and chlamydia, gonorrhea, and syphilis cases for all US counties in 2020. METHODS: Separate, adjusted multivariable quasi-Poisson models with robust standard errors modeled the county-level association between 2020 COVID-19 cases and deaths per 100,000 and 2020 chlamydia, gonorrhea, or syphilis cases per 100,000. Models were adjusted for sociodemographic characteristics. RESULTS: Every 1000 additional COVID-19 cases per 100,000 was associated with a 1.80% increase in the average number of chlamydia cases ( P < 0.001) and a 5.00% increase in the average number of gonorrhea cases ( P < 0.001). Every 1000 additional COVID-19 deaths per 100,000 was associated with a 57.9% increase in the average number gonorrhea cases ( P < 0.001) and a 74.2% decrease in the average number of syphilis cases ( P = 0.004). CONCLUSIONS: Higher rates of COVID-19 cases and deaths were associated with increased rates of some STIs at the US county level. The underlying reasons for these associations could not be established by this study. The emergency response to an emerging threat may have unanticipated influence on preexisting diseases that varies by level of governance.

Age Patterns of HSV-2 Incidence and Prevalence in Two Ugandan Communities: A Catalytic Incidence Model Applied to Population-Based Seroprevalence Data.

BACKGROUND: Herpes simplex virus type 2 (HSV-2) is an incurable sexually transmitted infection associated with increased risk of acquiring and transmitting human immunodeficiency virus (HIV). HSV-2 is highly prevalent in sub-Saharan Africa, but population-level estimates of incidence are sparse. METHODS: We measured HSV-2 prevalence from cross-sectional serological data among adults aged 18-49 years in 2 south-central Uganda communities (fishing, inland). We identified risk factors for seropositivity, then inferred age patterns of HSV-2 with a Bayesian catalytic model. RESULTS: HSV-2 prevalence was 53.6% (n = 975/1819; 95% confidence interval, 51.3%-55.9%). Prevalence increased with age, was higher in the fishing community, and among women, reaching 93.6% (95% credible interval, 90.2%-96.6%) by age 49 years. Factors associated with HSV-2 seropositivity included more lifetime sexual partners, HIV positive status, and lower education. HSV-2 incidence peakied at age 18 years for women and 19-20 years for men. HIV prevalence was up to 10-fold higher in HSV-2-positive individuals. CONCLUSIONS: HSV-2 prevalence and incidence were extremely high, with most infections occurring in late adolescence. Interventions against HSV-2, such as future vaccines or therapeutics, must target young populations. Remarkably higher HIV prevalence among HSV-2-positive individuals underscores this population as a priority for HIV prevention.

The Future of Sexually Transmitted Infection Research: Understanding Adolescent Perspectives for Implementation of a Chlamydia Vaccine.

PURPOSE: Despite advancements in developing a vaccine for Chlamydia trachomatis (CT), vaccine hesitancy has historically limited the adoption of sexually transmitted infection immunization. This report investigates adolescent perspectives toward a potential CT vaccine and vaccine research. METHODS: As part of the Technology Enhanced Community Health Nursing (TECH-N) study, conducted from 2012-2017, we surveyed 112 adolescents and young adults aged 13-25 years who presented with pelvic inflammatory disease regarding their perspectives on a CT vaccine and willingness to participate in vaccine research. Descriptive statistical analyses were conducted. RESULTS: Most participants were African American (95%), on Medicaid (89%), and sexually experienced (100%). Most respondents would accept a vaccine (95%) and preferred a provider's recommendation (86%) over parents, partners, or friends. A majority (70%) would not be embarrassed to participate in research. DISCUSSION: Respondents showed favorable attitudes toward CT vaccination and research in this high-risk study population.

The Acceptability of Self-Collected Samples for STI Testing: A Qualitative Study Among Adults in Rakai, Uganda.

Introduction: Self-collected samples (SCS) for sexually transmitted infection (STI) testing have been shown to be feasible and acceptable in high-resource settings. However, few studies have assessed the acceptability of SCS for STI testing in a general population in low-resource settings. This study explored the acceptability of SCS among adults in south-central Uganda. Methods: Nested within the Rakai Community Cohort Study, we conducted semi-structured interviews with 36 symptomatic and asymptomatic adults who self-collected samples for STI testing. We analyzed the data using an adapted version of the Framework Method. Results: Overall, participants did not find SCS physically uncomfortable. Reported acceptability did not meaningfully differ by gender or symptom status. Perceived advantages to SCS included increased privacy and confidentiality, gentleness, and efficiency. Disadvantages included the lack of provider involvement, fear of self-harm and the perception that SCS was unhygienic. Most participants preferred provider-collected samples to SCS. Nevertheless, almost all said they would recommend SCS and would do it again in the future. Conclusion: Despite a preference for provider-collection, SCS are acceptable among adults in this setting and support expanded access to STI diagnostic services.

Preschool-Aged Household Contacts as a Risk Factor for Viral Respiratory Infections in Healthcare Personnel.

Background: Viral respiratory infections (VRIs) are common and are occupational risks for healthcare personnel (HCP). VRIs can also be acquired at home and other settings among HCPs. We sought to determine if preschool-aged household contacts are a risk factor for VRIs among HCPs working in outpatient settings. Methods: We conducted a secondary analysis of data from a cluster randomized trial at 7 medical centers in the United States over 4 influenza seasons from 2011-2012 to 2014-2015. Adult HCPs who routinely came within 6 feet of patients with respiratory infections were included. Participants were tested for respiratory viruses whenever symptomatic and at 2 random times each season when asymptomatic. The exposure of interest was the number of household contacts 0-5 years old (preschool-aged) at the beginning of each HCP-season. The primary outcome was the rate of polymerase chain reaction-detected VRIs, regardless of symptoms. The VRI incidence rate ratio (IRR) was calculated using a mixed-effects Poisson regression model that accounted for clustering at the clinic level. Results: Among the 4476 HCP-seasons, most HCPs were female (85.4%) and between 30 and 49 years of age (54.6%). The overall VRI rate was 2.04 per 100 person-weeks. In the adjusted analysis, HCPs having 1 (IRR, 1.22 [95% confidence interval {CI}, 1.05-1.43]) and ≥2 (IRR, 1.35 [95% CI, 1.09-1.67]) preschool-aged household contacts had higher VRI rates than those with zero preschool-aged household contacts. Conclusions: Preschool-aged household contacts are a risk factor for developing VRIs among HCPs working in outpatient settings.

Landscape Review of Mail-in Self-Collection, Programs for Sexually Transmitted Infections.

BACKGROUND: Mail-in self-collection of samples with centralized reference laboratory sexually transmitted infection (STI) testing has been shown to be feasible with equivalent performance. Commercial, fee-for-service mail-in testing Web sites seem to be popular. These sites are currently unregulated by the US Food and Drug Administration. METHODS: To compile a list of US organizations offering mail-in testing for STIs/HIV, the phrases "mail-in STI testing" and "home STI testing" were entered into search engines. Supplementary information was collected by organization email or "Contact Us" submission. RESULTS: Information was collected from 20 programs in the United States offering STI mail-in, self-collection testing services. Five programs (25%) were free to consumers. Six organizations (30%) only offered prefixed kits (STIs tested could not be selected). Half of the organizations provided extragenital testing, 2 (10%) did not provide extragenital testing, and the 8 others (40%) did not clarify. Three organizations (15%) used their own laboratory, 11 (55%) did not provide laboratory information. One commercial laboratory provided services to 5 organizations. CONCLUSIONS: Mail-in self-collection services are ubiquitous and exist in all states except 2; STI testing public health programs that offer testing at no cost to the consumer are only in 46% of states. Mail-in testing is likely a permanent fixture in sexual health services and will be an important component of a hybrid approach that complements that of static clinic services.

Added Value of Extragenital Sexually Transmitted Infection Testing in "IWantTheKit" Program Users.

BACKGROUND: The 2021 Centers for Disease Control and Prevention sexually transmitted infection treatment guidelines recommend extragenital testing for gonorrhea and chlamydia in men who have sex with men and for women based on reported behaviors and exposures. The "IWantTheKit (IWTK)" program is a free online platform for specimen self-collection and mail-in for combined chlamydia/gonorrhea testing. We sought to assess the additional diagnostic value of extragenital testing compared with genital testing only for chlamydia/gonorrhea and determine factors associated with a positive extragenital test result among IWTK users. METHODS: From August 2013 to January 2022, 7612 unique IWTK users returned swabs for testing; 3407 (45%) users requested both genital and extragenital tests and were included in this analysis. Descriptive statistics were summarized for demographic characteristics, reported behaviors, and genital and extragenital test results, and data were stratified by gender and age group. A logistic regression model was used to estimate associations between factors and extragenital sexually transmitted infection positivity. RESULTS: Chlamydia positivity rates were 4.7%, 2.4%, and 1.5% at genital, extragenital, and both sites, respectively; for gonorrhea, 0.4%, 1.1%, and 0.4% were positive at those sites, respectively. Among women, age 25 years and younger was significantly associated with extragenital chlamydia (odds ratio [OR], 4.0; P = 0.010). Being in high-risk quiz score group was associated with extragenital chlamydia (OR, 2.6; P = 0.005) and extragenital gonorrhea in men and women (OR, 8.5; P = 0.005). CONCLUSIONS: Extragenital testing detected additional chlamydia and gonorrhea cases in the IWTK user population that would have been missed by genital-only testing, especially for women younger than 25 years and people reported to be at high risk.

The HIV and sexually transmitted infection syndemic following mass scale-up of combination HIV interventions in two communities in southern Uganda: a population-based cross-sectional study.

BACKGROUND: Combination HIV prevention and treatment interventions (CHIs) have led to substantial declines in HIV incidence in sub-Saharan Africa; however, population-level data on non-HIV sexually transmitted infections (STIs) in the context of CHIs are rare. We aimed to assess STI burden following scale-up of CHIs in Uganda. METHODS: The Sexually Transmitted Infection Prevalence Study (STIPS) was a cross-sectional study nested within a population-based cohort among inland agrarian and Lake Victoria fishing populations in southern Uganda. STIPS enrolled consenting residents aged 18-49 years in two communities (one inland and one fishing) between May and October, 2019, and measured the prevalence of chlamydia, gonorrhoea, trichomonas, syphilis, and herpes simplex virus 2 (HSV-2). FINDINGS: Between May 27, 2019 and Oct 25, 2019, STIPS enrolled 1825 participants. HIV prevalence was 14·0% among the inland population and 39·8% among the fishing population, with about 90% HIV viral load suppression in both communities. Among inland and fishing populations, chlamydia prevalence was 9·6% (95% CI 7·9-11·7) and 9·9% (8·1-12·0), gonorrhoea prevalence 5·0% (3·8-6·7) and 8·4% (6·8-10·5), trichomonas prevalence 9·4% (7·7-11·5) and 12·2% (10·2-14·5), and HSV-2 prevalence 43·0% (39·9-46·3) and 64·4% (61·3-67·6), respectively. In the fishing population, syphilis seropositivity was 24·2% (21·5-27·2) with 9·4% (7·7-11·5) having high-titre (rapid plasma reagin ≥1:8) infection, including 16·9% (11·9-24·0%) of men living with HIV. Prevalence of at least one curable STI (chlamydia, gonorrhoea, trichomonas, or high-titre syphilis) was 51% higher among people living with HIV (vs HIV negative; adjusted prevalence risk ratio [PRR] 1·51; 95% CI 1·27-1·78), including among pregnant women (adjusted PRR 1·87, 1·11-3·17), with no differences by HIV suppression status. INTERPRETATION: Despite near universal HIV treatment, STI burden remains extremely high in southern Uganda, particularly among people living with HIV. There is an urgent need to integrate STI care with HIV services in African settings. FUNDING: National Institutes of Health.

Advancing Sexual Harassment Prevention and Elimination in the Sciences: "Every ... Health Organization Must Do Something Similar".

BACKGROUND: Sexual harassment is pervasive in science. A 2018 report found that the prevalence of sexual harassment in academia in the United States is 58%. An activity held at an international scientific congress was designed to advance sexual harassment prevention and elimination and empower binary and nonbinary persons at risk for harassment, discrimination, and violence. The objective is to describe the activity and outcomes to provide a promising model for other scientific communities. METHODS: A description of the plenary and key components as well as the data collection and analysis of selected outcomes are provided. RESULTS: Among 1338 congress participants from 61 countries, 526 (39%) attended the #MeToo plenary, and the majority engaged in some way during the plenary session. Engagement included standing for the pledge (~85%), participating in the question and answer session (n = 5), seeking counseling (n = 3), and/or providing written post-it comments (n = 96). Respondents to a postcongress survey (n = 388 [24% of all attendees]) ranked the plenary as number 1 among 14 congressional plenaries. In postanalysis, the written post-it comments were sorted into 14 themes within 6 domains, including: (1) emotional responses, (2) barriers to speaking out, (3) public health priorities, (4) reframing narratives about the issue, (5) allyship, and (6) moving the issue forward. CONCLUSIONS: Scientific organizations, agencies, and institutions have an important role to play in setting norms and changing enabling policies toward a zero-tolerance culture of sexual harassment. The activity presented offers a promising model for scientific communities with similar goals. The outcomes suggest that the plenary successfully engaged participants and had a measurable impact on the participants.

Risk of seroconversion and seroreversion of antibodies to Chlamydia trachomatis pgp3 in a longitudinal cohort of children in a low trachoma prevalence district in Tanzania.

BACKGROUND: Serologic testing for chlamydial antibodies is one potential tool for trachoma monitoring. Understanding the dynamics of seroconversion and seroreversion in low endemic districts is critical for determining the value of using serology. METHODOLOGY/PRINCIPAL FINDINGS: We surveyed a random sample of 2536 children aged 1-9 years in Kongwa, Tanzania, over three years; 1719 (67.8%) participants had all three follow-ups. Surveys assessed trachomatous inflammation-follicular (TF), Chlamydia trachomatis infection, and anti-pgp3 antibodies. Mass drug administration occurred immediately after the first and second follow-up surveys. The cohort was classified into trajectories of change in serostatus, and risk factors were evaluated for seroconversion and seroreversion. We found that 86.2% of seropositives remained seropositive throughout the study, whereas 12.1% seroreverted. Seroreverters were younger (Odds Ratio [OR] = 0.88 for every one-year increase in age, 95% CI = 0.79-0.99). 84.5% of seronegatives remained seronegative, and 13.0% seroconverted. Seroconverters were also younger (OR = 0.92, 95% CI = 0.87-0.98). Seroconversion and seroreversion were not explained by indeterminate values for the intensity of antibody response. Less than 1% of the cohort had unstable changes in serostatus, mostly explained by values in the indeterminate range. TF and infection in the cohort declined over time, while seropositivity increased from 31.5% to 36.4%. CONCLUSIONS/SIGNIFICANCE: Antibody status is relatively stable over time. Both seroconversion and seroreversion occurred over the three years in this low endemic district, especially in younger children. Modeling seroreversion is important for accurate determination of seroconversion. The use of serology as a monitoring tool should target the younger aged children as they will most likely capture recent changes in serostatus.
