ABSTRACT

BACKGROUND: Young Black gay and bisexual men (YBGBM) in the United States face significant disparities in HIV care outcomes. Mobile health (mHealth) interventions have shown promise with improving outcomes for YBGBM across the HIV care continuum. METHODS: We developed an mHealth application using human-centered design (HCD) from 2019-2021 in collaboration with YBGBM living with HIV and with HIV service providers. Our HCD process began with six focus groups with 50 YBGBM and interviews with 12 providers. These insights were used to inform rapid prototyping, which involved iterative testing and refining of program features and content, with 31 YBGBM and 12 providers. We then collected user feedback via an online survey with 200 YBGBM nationwide and usability testing of a functional prototype with 21 YBGBM. RESULTS: Focus groups and interviews illuminated challenges faced by YBGBM living with HIV, including coping with an HIV diagnosis, stigma, need for social support, and a dearth of suitable information sources. YBGBM desired a holistic approach that could meet the needs of those newly diagnosed as well as those who have been living with HIV for many years. Program preferences included video-based content where users could learn from peers and experts, a range of topics, a community of people living with HIV, and tools to support their health and well-being. Providers expressed enthusiasm for an mHealth program to improve HIV care outcomes and help them serve clients. Rapid prototyping resulted in a list of content topics, resources, video characteristics, community features, and mHealth tools to support adherence, retention, goal setting, and laboratory results tracking, as well as tools to help organization staff to support clients. Online survey and usability testing confirmed the feasibility, acceptability, and usability of the content, tools, and features. CONCLUSIONS: This study demonstrates the potential of a video-based mHealth program to address the unique needs of YBGBM living with HIV, offering support and comprehensive information through a user-friendly interface and videos of peers living with HIV and of experts. The HCD approach allowed for continuous improvements to the concept to maximize cultural appropriateness, utility, and potential effectiveness for both YBGBM and HIV service organizations.

ABSTRACT

Genital herpes is a chronic, lifelong sexually transmitted viral infection, which can cause recurrent, self-limited genital ulcers. It is caused by herpes simplex virus (HSV) type 1 and type 2 viruses. Genital HSV infection is a very prevalent STI, which causes self-limited, recurrent genital ulcers. Treatment decreases duration of symptoms and signs and can be provided as episodic or suppressive therapy. Genital herpes can have a substantial impact during pregnancy and on sexual health in general. Counseling on natural history, transmission, treatment, and management of sexual partners is an integral part of management of genital herpes.

ABSTRACT

BACKGROUND: As a potential indicator of equity in research partnerships, we conducted a bibliometric analysis of author affiliations and author order in publications about sub-Saharan Africa published in the journal Sexually Transmitted Diseases . METHODS: We identified articles in the journal Sexually Transmitted Diseases that were about sub-Saharan Africa and published from 2011 to 2020. Medical Subject Heading terms in PubMed were used to identity articles about sub-Saharan Africa. Authors with at least 1 affiliation in sub-Saharan Africa were characterized as sub-Saharan Africa-affiliated authors. RESULTS: Of the 1439 articles that were published in Sexually Transmitted Diseases from 2011 to 2020, 148 (10%) had a Medical Subject Heading term for a sub-Saharan African country. Of the 604 authors of these 148 articles, 53 (36%) of the first authors, 493 (53%) of the middle authors, and 58 (40%) of the last authors had a sub-Saharan African affiliation; 13 (8.8%) of the articles had no authors with a sub-Saharan African affiliation. The proportions of sub-Saharan African-affiliated authors in first and last authorship positions did not change significantly from 2011-2015 (77 articles) to 2016-2020 (71 articles). CONCLUSIONS: The underrepresentation of Africans in first and last authorship positions suggests power imbalances in global scientific partnerships. Funders, researchers, editors, publishers, and grant and manuscript reviewers each have roles in promoting equity in global health research. This study may serve as an example for journals to establish benchmarks and monitor progress toward a more equitable research environment.

ABSTRACT

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.

ABSTRACT

BACKGROUND: Women who attend sexual health clinics are at high risk for sexually transmitted infections and unintended pregnancy. Long-acting reversible contraceptives (LARC) are very effective contraceptive methods, but the provision of LARC in such clinics is not well described in the literature. METHODS: We conducted a retrospective chart review of women who presented to Denver Sexual Health Clinic for any reason and received family planning services between April 1, 2016, and October 31, 2018. We assessed demographic and clinical factors associated with contraceptive method received and conducted a subanalysis of those with intrauterine device (IUD) insertions on the same-day versus delayed insertion. Among those who received an IUD, we assessed rates of pelvic inflammatory disease (PID) 30 days after insertion. RESULTS: Of the 5064 women who received family planning services in our clinic, 1167 (23%) were using a LARC method at the time of their visit. Of the 3897 who were not using a LARC, fewer women, 12.6%, chose LARC (IUD and progestin implant), compared with 33.3% who chose new short-acting reversible contraceptives. Further analysis of the 270 IUD initiators revealed 202 (74.8%) received the IUD on the same day, whereas 68 (25.2%) had delayed IUD insertion. There were 9 incident cases of gonorrhea or chlamydia in those who received same-day IUD and 1 incident case among those who had delayed IUD insertion. There were no cases of PID at 30 days after insertion in either group. CONCLUSIONS: Study findings support IUD provision in a sexual health clinic on the day of initial visit without increased risk of PID.

ABSTRACT

BACKGROUND: The National Network of Sexually Transmitted Disease Clinical Prevention Training Centers (NNPTC) trains clinical providers to diagnose and treat sexually transmitted infections (STIs) in the United States. The purpose of this study was to examine the demographics of clinical providers and to correlate the number of training episodes with STI rates at the county level. METHODS: Registration data were collected between April 1, 2015, and March 31, 2020, in a custom Learning Management System from clinical providers taking NNPTC training. Using the 2018 STI surveillance data, counties were divided into quartiles based on reportable STI case rates and the number of county-level training events was compared per quartile. Univariate and multivariate analyses were conducted in IBM SPSS Statistics 23 (Armonk, NY) and SAS Enterprise Guide 7.1 (Cary, NC). RESULTS: From 2015 to 2020, the NNPTC trained 21,327 individuals, predominantly in the nursing professions and working in a public health environment. In multivariate analysis, the number of training events was significantly associated with higher STI rates at the county level (P < 0.0001) and the state where a prevention training center is located (P < 0001). CONCLUSIONS: The analysis suggests that NNPTC trainings are reaching the clinical providers working in geographic areas with higher STI rates.

ABSTRACT

BACKGROUND: A journal's quality is often assessed by its impact factor, a measure of the number of times a journal's published articles are cited in the scientific literature. However, the impact factor may not adequately measure a journal's influence on practice. As an alternative approach, we analyzed referenced articles of the 2015 and 2021 Centers for Disease Control and Prevention Sexually Transmitted Infections (STI) Treatment Guidelines, arguably the most influential document on STI prevention and care in the Unites States. METHODS: Referenced articles in the 2015 and 2021 guidelines were abstracted and analyzed by source and year of publication, and sources were ranked by frequency of citation. RESULTS: Of 892 citations in 2015 and 1454 citations in 2021, the most frequently cited reference sources included the journals Sexually Transmitted Diseases (14.0% and 12.8% in 2015 and 2021, respectively), Clinical Infectious Diseases (7.5% and 8.2%), and Sexually Transmitted Infections (5.6% and 6.4%). CONCLUSIONS: Sexually transmitted infection specialty journals influence STI prevention and practice beyond what would be expected from the journals' impact factor alone.

ABSTRACT

ABSTRACT: Despite decades of medical, diagnostic, and public health advances related to diagnosis and management of sexually transmitted infections (STIs), rates of reportable STIs continue to grow. A 2021 National Academies of Sciences, Engineering, and Medicine report on the current state of STI management and prevention in the United States, entitled Sexually Transmitted Infections: Adopting a Sexual Health Paradigm, offers recommendations on future public health programs, policy, and research. This new report builds upon the 1997 Institute of Medicine report, The Hidden Epidemic: Confronting Sexually Transmitted Diseases, and provides 11 recommendations organized under 4 action areas: (1) adopt a sexual health paradigm, (2) broaden ownership and accountability for responding to STIs, (3) bolster existing systems and programs for responding to STIs, and (4) embrace innovation and policy change to improve sexual health. We present our interpretive synopsis of this report, highlighting elements of particular interest to STI and sexual health practitioners, including clinicians, researchers, disease intervention specialists, community outreach workers, and public health staff. The report asserts that it is possible to create a healthier and more equitable future where fewer adolescents and adults are infected, fewer babies are born with STIs, and people entering their sexual debut and continuing throughout the life span are taught the language and skills to conceptualize and enact their own vision for what it means to be sexually healthy.

ABSTRACT

Syphilis, which is caused by the sexually transmitted bacterium Treponema pallidum subsp. pallidum, has an estimated 6.3 million cases worldwide per annum. In the past ten years, the incidence of syphilis has increased by more than 150% in some high-income countries, but the evolution and epidemiology of the epidemic are poorly understood. To characterize the global population structure of T. pallidum, we assembled a geographically and temporally diverse collection of 726 genomes from 626 clinical and 100 laboratory samples collected in 23 countries. We applied phylogenetic analyses and clustering, and found that the global syphilis population comprises just two deeply branching lineages, Nichols and SS14. Both lineages are currently circulating in 12 of the 23 countries sampled. We subdivided T. p. pallidum into 17 distinct sublineages to provide further phylodynamic resolution. Importantly, two Nichols sublineages have expanded clonally across 9 countries contemporaneously with SS14. Moreover, pairwise genome analyses revealed examples of isolates collected within the last 20 years from 14 different countries that had genetically identical core genomes, which might indicate frequent exchange through international transmission. It is striking that most samples collected before 1983 are phylogenetically distinct from more recently isolated sublineages. Using Bayesian temporal analysis, we detected a population bottleneck occurring during the late 1990s, followed by rapid population expansion in the 2000s that was driven by the dominant T. pallidum sublineages circulating today. This expansion may be linked to changing epidemiology, immune evasion or fitness under antimicrobial selection pressure, since many of the contemporary syphilis lineages we have characterized are resistant to macrolides.

ABSTRACT

Sexually transmitted infections (STIs) represent a sizable, longstanding, and growing challenge and a national public health priority. A recent National Academies report outlines new directions for STI prevention and control, including the adoption of a new sexual health paradigm and broader ownership and accountability for addressing sexual health and STIs among diverse clinical and nonclinical actors. These recommendations have important implications for infectious disease providers with STI and human immunodeficiency virus (HIV) expertise. As part of the envisioned shift toward greater prioritization of sexual health across systems for healthcare and health promotion, STI and HIV specialty providers will need to increasingly take on responsibilities as leaders in the provision of STI-related training; provision of technical assistance; and alignment of clinical training curricula, licensing criteria, and practice guidelines for healthcare generalists.

ABSTRACT

ABSTRACT: Chlamydia, gonorrhea, and primary/secondary syphilis rates in 2018 were significantly higher in counties located in states without Medicaid expansion compared with those with Medicaid expansion. For sexually transmitted infections combined, 59.9% of counties without Medicaid expansion were in the highest 2 sexually transmitted infection rate quartiles compared with 42.2% of counties with Medicaid expansion (P < 0.0001).

ABSTRACT

BACKGROUND: In prevalence studies of sexually transmitted infections (STIs), investigators often provide syndromic management for symptomatic participants but may not provide specific treatment for asymptomatic individuals with positive laboratory test results because of the delays between sample collection and availability of results as well as logistical constraints in recontacting study participants. METHODS: To characterize the extent of this issue, 80 prevalence studies from the World Health Organization's Report on Global Sexually Transmitted Infection Surveillance, 2018, were reviewed. Studies were classified as to whether clinically relevant positive results were returned or if this was not specified. RESULTS: More than half (56%) of the cited studies did not specify if participants were notified of clinically relevant positive STI test results. The percentages were similar for low- and middle-income country populations (57%) and high-income country populations (53%). CONCLUSIONS: The absence of documentation of the provision of test results raises the possibility that in some instances, results may not have been communicated, with potential negative effects for participants, their sexual partners, and newborns. From an ethical perspective, clinically relevant results should be returned to study participants and treating clinicians in a timely fashion to ensure appropriate management of identified infections. Study authors should document if they returned test results to study participants and report on numbers lost to follow-up.

ABSTRACT

BACKGROUND: Sexually transmitted disease clinical training for working professionals requires substantial time and resources. Understanding the predictors of change in worksite practices and barriers to change will allow educators, learners, and clinical leadership to aid in ensuring learned practices are implemented and barriers are addressed. METHODS: Data for this analysis come from the first standardized national evaluation of a Centers for Disease Control and Prevention-funded clinical prevention training network, including precourse registration and responses to immediate postcourse (1-3 days) and 90-day postcourse evaluations from 187 courses. Univariate statistics describe the trainees and their workplace. Bivariate statistics describe their intention to change and actual change stratified by functional role and employment setting. Logistic regression identified predictors of self-reported changes in practice. RESULTS: The strongest predictors for practice change included an intention to change and attendance at a training lasting 4 hours or more. Functional role was a weaker predictor of change in practice; employment setting did not predict change. More than half of the trainees (65.9%; n = 912) stated their intention to make a change in their practice immediately after training. At 90 days after a course, 62.4% (n = 863) reported making a practice change. Trainees that took courses lasting 4 hours or more reported making a change more often (70%) compared with trainees from shorter courses (53%). We also report on trainees' barriers to practice change. CONCLUSIONS: Results suggest that longer trainings may result in more practice change than shorter trainings, recruitment of trainees should focus on those more likely to make a change in their practice, and future trainings should focus on organizational capacity building and assessing change at the organizational level.

ABSTRACT

BACKGROUND: Cost-effective, scalable interventions are needed to address high rates of sexually transmitted diseases (STDs) in the United States. Safe in the City, a 23-minute video intervention designed for STD clinic waiting rooms, effectively reduced new infections among STD clinic clients. A cost-effectiveness analysis of this type of intervention could inform whether it should be replicated. METHODS: The cost-effectiveness of a brief video intervention was calculated under a baseline scenario in which this type of intervention was expanded to a larger patient population. Alternative scenarios included expanding the intervention over a longer period or to more clinics, including HIV prevention benefits, and operating the intervention part time. Program costs, net costs per STD case averted, and the discounted net cost of the intervention were calculated from a health sector perspective across the scenarios. Monte Carlo simulations were used to calculate 95% confidence intervals surrounding the cost-effectiveness measures. RESULTS: The net cost per case averted was $75 in the baseline scenario. The net cost of the intervention was $108,015, and most of the alternative scenarios found that the intervention was cost saving compared with usual care. CONCLUSIONS: Single session, video-based interventions can be highly cost effective when implemented at scale. Updated video-based interventions that account for the changing STD landscape in the United States could play an important role in addressing the recent increases in infections.

ABSTRACT

INTRODUCTION: Rising rates of reported sexually transmitted infections (STIs) in the US and Europe are a public health priority and require a public health response. The diagnosis and treatment of STIs have been the cornerstone of STI control and prevention for many decades and, historically, publicly funded STI clinics have played a central role in the provision of STI care. Innovations in non-invasive diagnostic techniques, especially nucleic acid amplification tests in the mid-1990s, have facilitated the expansion of STI testing and treatment outside traditional STI clinics, including primary care, family planning, school-based health, outreach, corrections, emergency departments and HIV prevention and care settings. As a result, the continued need for categorical STI clinics has been debated. In this Commentary, we discuss how practice can be improved at each level of STI care. DISCUSSION: STI practice improvement plans should be tailored to the strengths of each care setting. Thus, in primary care, the focus should be on improving STI screening rates, the provision of hepatitis B and human papillomavirus vaccines and, in jurisdictions where this is legal, expedited partner therapy for gonorrhoea and chlamydia. Extragenital (pharyngeal and rectal) testing for gonorrhoea and chlamydia should be available in settings serving populations more vulnerable to STI acquisition at these anatomical sites, including men who have sex with men. In family planning settings with a mostly female patient population, there are opportunities to serve male partners with both contraceptive and STI services. STI screening rates can also be improved in other settings serving populations at increased risk for STIs, including school-based clinics, emergency departments, correctional health facilities and providers of HIV care and prevention. These improvements are predominantly logistical in nature and not dependent on extensive STI clinical expertise. While some providers in these settings may have the clinical knowledge and skills to evaluate symptomatic patients, many do not, and STI speciality clinics must be available for consultation and referral and evolve from "safety net" providers of last resort to STI centres of excellence. CONCLUSIONS: A tailored practice improvement plan can be envisioned to achieve an optimally functioning STI care continuum.

ABSTRACT

Since 1979, the National Network of Sexually Transmitted Disease (STD) Clinical Prevention Training Centers (NNPTC) has provided state-of-the-art clinical and laboratory training for STD prevention across the United States. This article provides an overview of the history and activities of the NNPTC from its inception to present day, and emphasizes the important role the network continues to play in maintaining a high-quality STD clinical workforce. Over time, the NNPTC has responded to changing STD epidemiological patterns, technological advances, and increasing private-sector care-seeking for STDs. Its current structure of integrated regional and national training centers allows NNPTC members to provide dynamic, tailored responses to STD training needs across the country.

ABSTRACT

BACKGROUND: Dual human immunodeficiency virus (HIV)/syphilis rapid, point-of-care testing may enhance syphilis screening among high-risk populations, increase case finding, reduce time to treatment, and prevent complications. We assessed the laboratory-based performance of a rapid dual HIV/syphilis test using serum collected from patients enrolled in the Zimbabwe Sexually Transmitted Infections (STI) Etiology study. METHODS: Blood specimens were collected from patients presenting with STI syndromes in 6, predominantly urban STI clinics in different regions of Zimbabwe. All specimens were tested at a central research laboratory using the Standard Diagnostics Bioline HIV/Syphilis Duo test. The treponemal syphilis component of the dual rapid test was compared with the Treponema pallidum hemagglutination assay (TPHA) as a gold standard comparator, both alone or in combination with a nontreponemal test, the rapid plasma reagin test. The HIV component of the dual test was compared with a combination of HIV rapid tests conducted at the research laboratory following the Zimbabwe national HIV testing algorithm. RESULTS: Of 600 men and women enrolled in the study, 436 consented to serological syphilis and HIV testing and had specimens successfully tested by all assays. The treponemal component of the dual test had a sensitivity of 66.2% (95% confidence interval [CI], 55.2%-77.2%) and a specificity of 96.4% (95% CI, 94.5%-98.3%) when compared with TPHA; the sensitivity increased to 91.7% (95% CI, 82.6%-99.9%) when both TPHA and rapid plasma reagin were positive. The HIV component of the dual test had a sensitivity of 99.4% (95% CI, 98.4%-99.9%) and a specificity of 100% (95% CI, 99.9%-100%) when compared with the HIV testing algorithm. CONCLUSIONS: Laboratory performance of the SD Bioline HIV/Syphilis Duo test was high for the HIV component of the test. Sensitivity of the treponemal component was lower than reported from most laboratory-based evaluations in the literature. However, sensitivity of the test increased substantially among patients more likely to have active syphilis for which results of both standard treponemal and nontreponemal tests were positive.

ABSTRACT

BACKGROUND: Syphilis prevalence in sub-Saharan Africa appears to be stable or declining but is still the highest globally. Ongoing sentinel surveillance in high-risk populations is necessary to inform management and detect changes in syphilis trends. We assessed serological syphilis markers among persons with sexually transmitted infections in Zimbabwe. METHODS: We studied a predominantly urban, regionally diverse group of women and men presenting with genital ulcer disease (GUD), women with vaginal discharge and men with urethral discharge at clinics in Zimbabwe. Syphilis tests included rapid plasma reagin and the Treponema pallidum hemagglutination assay. RESULTS: Among 436 evaluable study participants, 36 (8.3%) tested positive for both rapid plasma reagin and Treponema pallidum hemagglutination assay: women with GUD: 19.2%, men with GUD: 12.6%, women with vaginal discharge: 5.7% and men with urethral discharge: 1.5% (P < 0.0001). CONCLUSIONS: Syphilis rates in Zimbabwe are high in sentinel populations, especially men and women with GUD.
