Syphilis Diagnosis After a Chlamydia, Gonorrhea, or HIV Diagnosis Among Reproductive-Aged Women in Baltimore, MD.

BACKGROUND: Syphilis incidence is increasing among reproductive-aged women, and previous sexually transmitted infections (STIs) are a risk factor for subsequent STIs. This study aimed to determine syphilis incidence after a chlamydia, gonorrhea, or HIV diagnosis, and identify characteristics associated with higher syphilis incidence rates among reproductive-aged women in 1 mid-Atlantic city. METHODS: A retrospective cohort of 85,113 chlamydia, gonorrhea, and HIV diagnoses occurring between 2009 and 2021 and among women aged 13 to 50 years was constructed using public health surveillance data. Cumulative incidence curves were estimated to examine time to early syphilis (i.e., primary, secondary, or early latent) diagnosis, and multivariable analyses determined incidence rate ratios by age (<25 vs. ≥25 years) and number of prior STI diagnoses (0 vs. ≥1) during the study period, stratified by STI. RESULTS: There were 85,113 reportable STI diagnoses and 646 syphilis diagnoses in the cohort. Approximately 1 of 150 chlamydia, 1 of 100 gonorrhea, and 1 of 50 HIV diagnoses were followed by a syphilis diagnosis within 5 years. Cumulative incidence of syphilis differed significantly by STI diagnosis ( P < 0.001). In multivariable analysis, syphilis incidence rates were higher among women diagnosed with ≥1 (vs. 0) prior STI regardless of STI type ( P < 0.05) and among women ≥25 (vs. <25) years old diagnosed with gonorrhea ( P < 0.05). CONCLUSIONS: There were significant differences in syphilis incidence by prior STI type, number of STIs, and age. Our data support targeted screening for syphilis among women with a history of STIs, parwomen with ≥1 prior STI diagnosis, and older women diagnosed with gonorrhea.

Social networks of people with serious mental illness who smoke: potential role in a smoking cessation intervention.

BACKGROUND: Smoking is a major contributor to morbidity and mortality among individuals with serious mental illness (SMI) and social networks may play an important role in smoking behaviors. AIMS: Our objectives were to (1) describe the network characteristics of adults with SMI who smoke tobacco (2) explore whether network attributes were associated with nicotine dependence. METHODS: We performed a secondary analysis of baseline data from a tobacco smoking cessation intervention trial among 192 participants with SMI. A subgroup (n = 75) completed questions on the characteristics of their social network members. The network characteristics included network composition (e.g. proportion who smoke) and network structure (e.g. density of connections between members). We used multilevel models to examine associations with nicotine dependence. RESULTS: Participant characteristics included: a mean age 50 years, 49% women, 48% Black, and 41% primary diagnosis of schizophrenia/schizoaffective disorder. The median personal network proportion of active smokers was 22%, active quitters 0%, and non-smokers 53%. The density of ties between actively smoking network members was greater than between non-smoking members (55% vs 43%, p = .02). Proportion of network smokers was not associated with nicotine dependence. CONCLUSIONS: We identified potential social network challenges and assets to smoking cessation and implications for network interventions among individuals with SMI.

Enacted Sexual Minority Stigma, Psychological Distress, and Sexual and Drug Risk Behaviors Among Urban Men Who Have Sex with Men (MSM).

Urban Black men who have sex with men (MSM) bear a disproportionate burden of HIV and syphilis in the U.S. Experiences of enacted sexual minority stigma and psychological distress among these men may be associated with HIV/STI sexual and drug risk behaviors. The objective was to determine the associations between enacted sexual minority stigma, psychological distress, and sexual and drug risk behaviors. In an urban prospective cohort study, survey measures assessed past 3-month exposure to enacted sexual minority stigma, psychological distress, and sexual and drug risk behaviors. Multivariable logistic regression models were utilized for hypothesis testing. The Black MSM (N = 140) reported the following: 22.1% experiences of enacted sexual minority stigma, 39% high levels of psychological distress, 48.6% > 1 sex partner, 8.6% transactional sex, and 6% injection drug use (IDU). In models adjusted for age and education, enacted sexual minority stigma significantly increased the odds of reporting > 1 sex partner, transactional sex, and IDU. Adjusting additionally for homelessness, the association between enacted sexual minority stigma and transactional sex remained significant. Adding psychological distress to this model showed a significant association between psychological distress and transactional sex, while the association was no longer significant for transactional sex. These findings highlight some of the complex psycho-social relationships that may be associated with sexual and drug risk behaviors among Black MSM placing them at increased risk for HIV and syphilis.

RESUMEN: Hombres urbanos de raza Negra que tienen sexo con hombres (HSH) sobrellevan una carga desproporcionada de VIH y sífilis en los EE.UU. Experiencias de estigma efectivo de minoría sexual y angustia psicológica entre estos hombres pudiese ser asociado con conductas sexuales de riesgo VIH/ITS y drogas. El objetivo era determinar las asociaciones entre un estigma efectivo de minoría sexual, angustia psicológica, y comportamientos sexuales y de riesgo de drogas. En un estudio de cohortes prospectivo urbano, las medidas de la encuesta evaluada en los últimos tres meses de exposición al estigma efectivo, angustia psicológica, y sus conductas sexuales y comportamientos riesgoso de drogas. Modelos de regresión logística multivariante se utilizaron para la prueba de hipótesis. Los HSH de raza negra (N = 140) reportaron lo siguiente: 22.1% experiencias de estigma efectivo, 39% niveles altos de angustia psicológica, 48.6% y > 1 pareja sexual, 8.6% sexo transaccional, y 6% uso de drogas inyectables (UDI). En modelos ajustados a edad y educación, un estigma efectivo de minoría sexual aumentó de manera significante las probabilidades de reportar y > 1 pareja sexual, sexo transaccional, y UDI. Ajustando adicionalmente para personas sin vivienda, la asociación entre estigma efectivo de minoría sexual y sexo transaccional permaneció significante. La adición de angustia psicológica al modelo mostró una asociación significativa entre angustia psicológica y sexo transaccional, mientras que la asociación ya no era significativa para el sexo transaccional. Estos resultados destacan algunas de las complejas relaciones psicosociales que pudiesen estar asociadas con conductas sexuales y de riesgo de drogas entre HSH de raza negra, poniéndolos a mayor riesgo de contraer VIH y sífilis.

Improving Research Dissemination to Black Sexual Minority Men: Development of a Community-Led and Theory-Based Dissemination Plan.

Background. Although research dissemination to participants and community stakeholders is a fundamental component of translational research, it rarely occurs. The objective of this study was to create a community-led, theory-based dissemination plan to engage local Black sexual minority men in an active dissemination process throughout a sexual health research study. Method. Seven focus groups (N = 38) were conducted with Black, cisgender sexual minority men aged 18 to 45 years. Findings were analyzed through thematic content analysis guided by McGuire's persuasive communication theory. Findings were used to draft a dissemination plan, which was then reviewed and edited by the study's community advisory board (CAB). The plan continues to be updated in response to community needs through CAB discussions. Results. Participants preferred messages concerning syphilis and other health concerns as well as information on local resources. Preferred sources included researchers working with trusted community organizations and leaders. Preferred channels included community events and social media, implemented with consistency. CAB feedback included expanding the target audience of dissemination efforts as well as the development of ideas for channels (i.e., events) and sources (i.e., community organizations and leaders). Additional revisions occurred in response to the COVID-19 pandemic. Conclusion. Given the continued lack of research dissemination to participant and community stakeholders, the process of developing a community-led, theory-based dissemination plan may benefit and help guide researchers to adopt this practice. It is critical that participant and community stakeholder dissemination become more highly prioritized as we strive for public health improvements and the elimination of health disparities.

Sexually Transmitted Infection Transmission Dynamics During the Coronavirus Disease 2019 (COVID-19) Pandemic Among Urban Gay, Bisexual, and Other Men Who Have Sex With Men.

BACKGROUND: The impact of coronavirus disease 2019 (COVID-19) mitigation measures on sexually transmitted infection (STI) transmission and racial disparities remains unknown. Our objectives were to compare sex and drug risk behaviors, access to sexual health services, and STI positivity overall and by race during the COVID-19 pandemic compared with pre-pandemic among urban sexual minority men (MSM). METHODS: Sexually active MSM aged 18-45 years were administered a behavioral survey and STI testing every 3-months. Participants who completed at least 1 during-pandemic (April 2020-December 2020) and 1 pre-pandemic study visit (before 13 March 2020) that occurred less than 6 months apart were included. Regression models were used to compare during- and pre-pandemic visit outcomes. RESULTS: Overall, among 231 MSM, reports of more than 3 sex partners declined(pandemic-1: adjusted prevalence ratio 0.68; 95% confidence interval: .54-.86; pandemic-2: 0.65, .51-.84; pandemic-3: 0.57, .43-.75), substance use decreased (pandemic-1: 0.75, .61-.75; pandemic-2: 0.62, .50-.78; pandemic-3: 0.61, .47-.80), and human immunodeficiency virus/preexposure prophylaxis care engagement (pandemic-1: 1.20, 1.07-1.34; pandemic-2: 1.24, 1.11-1.39; pandemic-3: 1.30, 1.16-1.47) increased. STI testing decreased (pandemic-1: 0.68, .57-.81; pandemic-2: 0.78, .67-.92), then rebounded (pandemic-3: 1.01, .87-1.18). Nei-ther Chlamydia (pandemic-2: 1.62, .75-3.46; pandemic-3: 1.13, .24-1.27) nor gonorrhea (pandemic-2: 0.87, .46 1.62; pandemic-3: 0.56, .24-1.27) positivity significantly changed during vs pre-pandemic. Trends were mostly similar among Black vs. non-Black MSM. CONCLUSIONS: We observed sustained decreases in STI risk behaviors but minimal change in STI positivity during compared with pre-pandemic. Our findings underscore the need for novel STI prevention strategies that can be delivered without in-person interactions.

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.

HIV Transmission Potential and Sex Partner Concurrency: Evidence for Racial Disparities in HIV Risk Among Gay and Bisexual Men (MSM).

We determined whether racial disparities in HIV infection among gay and bisexual men (MSM) may be partially explained by racial differences in the HIV transmission potential (i.e. mixing of people living with HIV and people not living with HIV or of unknown HIV serostatus) and density (i.e. sex partner concurrency) of sexual networks. Data included a behavioral survey, testing for HIV, and an egocentric sexual network survey. Mixed effects logistic regressions were used for hypothesis testing. Black (vs. non-Black) MSM were more likely to not know their partner's HIV serostatus (21.8% vs. 9.6%). Similar proportions reported sex partner concurrency (67.1% vs. 68.0%). In adjusted analyses, among Black MSM, sex partner concurrency significantly increased the odds of an HIV transmission potential partnership (TPP), and this association was not significant among non-Black indexes. The association between an HIV TPP and sex partner concurrency may help explain persistent racial disparities in HIV prevalence.

RESUMEN: Determinamos si las disparidades raciales en infecciones del VIH entre hombres homosexuales y bisexuales (hombres que tienen sexo con hombres) puede ser parcialmente explicado por diferencias raciales en el potencial de transmisión del VIH (es decir, mezcla de personas viviendo con VIH y personas que no viven con VIH o cuyo estado serológico del VIH es desconocido) y densidad (es decir, concurrencia de pareja sexual) de redes sexuales. Los datos incluyeron una encuesta de comportamiento, pruebas para el VIH y una encuesta de redes sexuales egocéntrica. Regresiones logísticas de efectos mixtos fueron usados para la prueba de hipótesis. HSH negros (vs. HSH no-negros) eran más propensos a no saber el estado serológico del VIH de su pareja (21.8% vs. 9.6%). Proporciones similares reportaron concurrencia de pareja sexual (67.1% vs. 68.0%). En análisis ajustados, entre HSH negros, la concurrencia de pareja sexual aumentó significativamente las probabilidades de una asociación potencial de transmisión del VIH (TPP por sus siglas en inglés), y esta asociación no fue significativa entre índices de no-negros. La asociación entre una TPP VIH y concurrencia de pareja sexual puede ayudar a explicar disparidades raciales persistentes en la prevalencia del VIH.

Acceptability and Feasibility of Geographically Explicit Ecological Momentary Assessment Among Men Who Have Sex with Men.

Syphilis among men who have sex with men (MSM) has increased greatly in the past twenty years in the U.S. Geographically explicit ecological momentary assessment (GEMA), in which behaviors are geotagged and contextualized in time and space, may contribute to a greater understanding of transmission risk. The objective was to determine the acceptability and feasibility of GEMA for assessing HIV and syphilis transmission risk behaviors among a sample of MSM. Participants responded to a brief survey five times a day for two weeks. Feasibility was measured by participant recruitment, enrollment, prompts received and answered, geotagged prompts, and technical interference with data collection. Acceptability was measured by ratings of enjoyment and willingness for future participation. Summaries of five behavioral measures from the brief survey were calculated. Among the 83 participants contacted, 67.5% (56) expressed interest, 98% (55) were scheduled, and 81.8% (45) were enrolled. Participants answered 78.3% (2,277) of prompts received and 87.7% (1,998) of answered prompts were geotagged. Overall, 70.5% (31) enjoyed participating and 91.1% (41) were willing to participate in the future. Among prompts answered, missingness was low for five behavioral measures (range 0.2% (4) to 0.7% (16)). Feasibility and acceptability were high and missingness was low on behavioral measures in this MSM study population. Most participants reported that they would participate again. Future work should focus on whether GEMA improves our understanding of syphilis and HIV transmission risk.

Methamphetamine Use, Syphilis, and Specific Online Sex Partner Meeting Venues Are Associated With HIV Status Among Urban Black Gay and Bisexual Men Who Have Sex Men.

BACKGROUND: In the context of increasing syphilis rates, particularly among Black men who have sex men (MSM), the objectives were to determine the associations between methamphetamine (meth) use and syphilis and HIV positivity, and to identify sex partner meeting venues as potential intervention access points among Black MSM in a mid-Atlantic US city. METHODS: This study is an ongoing longitudinal cohort study. Participants were recruited from clinical and nonclinical settings and included sexually active MSM aged 18 to 45 years. The baseline visit included a behavioral survey and testing for syphilis, HIV, gonorrhea, and chlamydia. Logistic regression analyses were used for hypothesis testing. RESULTS: Among 359 MSM completing baseline, 74.4% (268) Black MSM were included; 31% (84) were aged 24 to 29 years, 43.7% (117) reported unprotected anal intercourse at last sex, and 15.3% (41) reported meth use in the past 3 months. Sixteen percent (43) had syphilis, 46.6% (125) were living with HIV, and 19.0% (51) had gonorrhea and/or chlamydia. Meth use was associated with sexual and drug risk behaviors and HIV, but not syphilis. In adjusted analyses, meth use increased the odds of HIV positivity by 6.43 (95% confidence interval, 2.30-17.98) and syphilis positivity by 2.57 (95% confidence interval, 1.23-5.37). Four online sex partner meeting venues were associated with meth use and HIV, whereas syphilis was associated with one. CONCLUSIONS: Among Black MSM, meth use and syphilis positivity were associated with more than 6-fold and almost 3-fold increased adjusted odds of HIV positivity, respectively. Four specific sex partner meeting venues may be important access points for HIV/sexually transmitted infection and substance use prevention.

Parent, partner and individual contexts of very early first sex experiences among young men and their links to subsequent reproductive health outcomes.

Research indicates that upwards to 30% of US urban Black male adolescents report first sex younger than age 13; however, there is limited literature on the sexual and reproductive health outcomes and contexts of these early first sex experiences. This exploratory study described sexual and reproductive health histories and explored personal, partner and parent contextual factors associated with first sex experiences occurring at 13 years or younger among a sample of US urban young men aged 15-24. Participants were assessed on their demographics and sexual health histories and a subset of young men were assessed on the contextual factors related to their first sex experience. Pearson chi-squared tests examined factors associated with early first sex and Fisher's exact tests examined associated contextual factors. First sex at 13 years or younger was reported by 29% of young men. A higher proportion of young men who had first sex at 13 or younger than those who had sex onset at 14 or older reported having got someone pregnant, having a "much older" first partner, and relationship satisfaction with their mother (16%) and father (12%). Study findings highlight the need to better understand urban young men's early first sex experiences, including the support needed to promote their healthy sexual development.

Community engagement and linkage to care efforts by peer community-health workers to increase PrEP uptake among sexual minority men.

PURPOSE: Pre-exposure prophylaxis (PrEP) prevents HIV yet uptake remains suboptimal across the United States. This paper evaluates the impact of outreach activities led by nurse supervised community healthcare workers (CHWs) on the PrEP care cascade. METHODS: This is an observational programmatic evaluation of LGBTQ + community outreach between March 1, 2016, to March 31, 2020, as part of a public health initiative. Descriptive statistics are used to characterize the data by outreach type. RESULTS: 2,465 participants were reached. Overall, a PrEP appointment was scheduled for 94 (3.8%) with 70 (2.8%) confirmed to have completed a PrEP visit. Success for each type of community outreach activity was evaluated with virtual models outperforming face-to-face. Face-to-face outreach identified nine persons among 2,188 contacts (0.41%) completing an initial PrEP visit. The website prepmaryland.org identified 4 among 24 contacts (16.7%) and the PrEP telephone/text warm-line identified 18 among 60 contacts (30%). The PrEPme smartphone application identified 39 among 168 contacts (23.2%). CONCLUSIONS: Face-to-face community outreach efforts reached a large number of participants, yet had a lower yield in follow-up and confirmed PrEP visits. All virtual platforms reached lower total numbers, but had greater success in attendance at PrEP visits, suggesting enhanced linkage to care.

Recommendations From Black Sexual Minority Men: Building Trust to Improve Engagement and Impact of HIV/STI Research.

As demonstrated by the consistently documented disproportionately high rates of HIV and STIs (sexually transmitted infections) among Black sexual minority men (BSMM), current efforts to develop responsive interventions to reduce HIV and other STIs within this population have not been sufficient. It is therefore critical that public health researchers reflect meaningfully on the ways in which they investigate HIV and STIs. Engagement with BSMM is crucial in addressing the disproportionately high rates of HIV and STIs experienced, and thus the goal of the current research was to identify community-developed strategies that may enhance community engagement in research with BSMM. Seven focus groups (N = 38) were held with cisgender BSMM ages 18 to 45 years in Baltimore, Maryland to explore how to better engage this population and improve HIV and STI research. Data analysis of the text was conducted using an iterative, thematic constant comparison process informed by grounded theory. Four distinct themes related to trust-building within the broader community emerged: (1) authentic engagement with the community, (2) increased transparency of the research process, (3) capacity building of research staff from the community, and (4) a balance of research and action. Strategies for researchers to build community trust were identified that are related to, but slightly distinct from, common discussions in the community engaged research literature that are centered more specifically on trust-building within community-academic partnerships. Engagement with BSMM is crucial in addressing HIV and STI health disparities. It is critical that community engagement also be a priority to policy makers, research institutions, and funding institutions.

Sexually Transmitted Infection Screening Among Gay, Bisexual, and Other Men Who Have Sex With Men Prescribed Pre-exposure Prophylaxis in Baltimore City, Maryland.

BACKGROUND: Human immunodeficiency virus pre-exposure prophylaxis (PrEP) clinical guidelines recommend men who have sex with men (MSM) PrEP users be screened biannually for syphilis and gonorrhea/chlamydia at all anatomic sites. We sought to determine the proportion screened and positive by STI and anatomic site at PrEP initiation and PrEP-care visits and patient-level characteristics associated with screening among MSM PrEP users in Baltimore City, Maryland. METHODS: Medical records among MSM initiating PrEP between 30 September 2015 and 31 March 2018 were abstracted. STI screening (syphilis and gonorrhea/chlamydia at all anatomic sites) and positivity at PrEP visits ≤12 months following initiation were calculated. Poisson regression with cluster robust SEs was used to assess associations with STI screening. RESULTS: Among 290 MSM initiating PrEP, 43.1% (n = 125) were screened per guidelines at PrEP initiation; 79.3% (230), 69.3% (201), 55.9% (162), and 69.3% (201) were screened for syphilis, urogenital, rectal, and oropharyngeal gonorrhea/chlamydia, respectively. Positivity among those screened was syphilis, 7.8% (n = 18/230); gonorrhea, 5.0% urogenital (10/201), 11.1% rectal (18/162), and 7.5% oropharyngeal (15/201); chlamydia, 5.0% urogenital (10/201), 11.7% rectal (19/162), and 1.5% oropharyngeal (3/201). Reported anal and oral sex (vs neither) was independently associated with STI screening (aPR, 2.11; 1.05-4.27) at PrEP initiation. At biannual PrEP-care visits, STI screening was lower and syphilis and rectal gonorrhea/chlamydia positivity was higher. CONCLUSIONS: Observed STI screening levels and disease burden suggest the effectiveness of STI screening in PrEP care for STI prevention may be limited. Our results suggest providers may be offering screening based on sexual practices; clarification of STI screening guidelines for PrEP users is needed.

Overlapping Transmission Networks of Early Syphilis and/or Newly HIV Diagnosed Gay, Bisexual and Other Men Who Have Sex with Men (MSM): Opportunities for Optimizing Public Health Interventions.

Syphilis and HIV among gay, bisexual and other men who have sex with men (MSM) are syndemic suggesting current prevention strategies are not effective. Sex partner meeting places and their networks may yield effective and optimal interventions. From 2009 to 2017, 57 unique venues were reported by > 1 MSM and 7.0% (n = 4), 21.1% (n = 12) and 71.9% (n = 41) were classified as syphilis, HIV or co-diagnosed venues, respectively. Forty-nine venues were connected in one main network component with four online, co-diagnosis venues representing 51.6% of reports and the highest degree and eigenvector centralities. In a sub-analysis during a local syphilis epidemic, the proportion of venues connected in the main component increased 38.7% (61.5% to 86.4%); suggesting increasing overlap in syphilis and HIV transmission and density of the venue network structure over time. This network analysis may identify the optimal set of venues for tailored interventions. It also suggests increasing difficulty of interrupting network transmission through fragmentation.

The Association Between Social Support, Violence, and Social Service Needs Among a Select Sample of Urban Adults in Baltimore City.

Experiencing violence has been associated with negative health outcomes. The objectives of this study were to determine whether experiencing violence is associated increased support service needs and suboptimal general health indicators. In addition, we explore the relationship between these and perceived social support among a select sample of urban predominantly male adults in Baltimore City. A cross-sectional survey was conducted among 187 adults being seen in one of seven urban partner agencies participating in a parent HIV prevention and treatment demonstration project. Associations were examined using a multivariable logistic regression model, adjusting for the clinic site at which the client was being seen as well as age and gender identity. There was a significant amount of violence experienced by this population; 131 (72%) reported having seen someone be physically assaulted, and 89 (49%) had been physically assaulted without a weapon. Direct victimization from violence was associated with a threefold increased odds of needing housing and mental health/substance use services. Exposure to violence was associated with a threefold increase in needing housing and mental health/substance use services, and with sub-optimal health status. Perceived social support was associated with 30% decreased reports of experiencing violence. In conclusion, our select sample of urban adults report having experienced high rates of violence, and this is associated with increased support service needs as well as suboptimal perceived health status. Incorporating care for the effects of experiencing violence as well as social service needs are important in optimizing the health of urban populations.

Comparison of Frequency- and Time-Domain Autoregulation and Vasoreactivity Indices in a Piglet Model of Hypoxia-Ischemia and Hypothermia.

INTRODUCTION: The optimal method to detect impairments in cerebrovascular pressure autoregulation in neonates with hypoxic-ischemic encephalopathy (HIE) is unclear. Improving autoregulation monitoring methods would significantly advance neonatal neurocritical care. METHODS: We tested several mathematical algorithms from the frequency and time domains in a piglet model of HIE, hypothermia, and hypotension. We used laser Doppler flowmetry and induced hypotension to delineate the gold standard lower limit of autoregulation (LLA). Receiver operating characteristics curve analyses were used to determine which indices could distinguish blood pressure above the LLA from that below the LLA in each piglet. RESULTS: Phase calculation in the frequency band with maximum coherence, as well as the correlation between mean arterial pressure (MAP) and near-infrared spectroscopy relative total tissue hemoglobin (HbT) or regional oxygen saturation (rSO2), accurately discriminated functional from dysfunctional autoregulation. Neither hypoxia-ischemia nor hypothermia affected the accuracy of these indices. Coherence alone and gain had low diagnostic value relative to phase and correlation. CONCLUSION: Our findings indicate that phase shift is the most accurate component of autoregulation monitoring in the developing brain, and it can be measured using correlation or by calculating phase when coherence is maximal. Phase and correlation autoregulation indices from MAP and rSO2 and vasoreactivity indices from MAP and HbT are accurate metrics that are suitable for clinical HIE studies.

Human Immunodeficiency Virus Diagnosis After a Syphilis, Gonorrhea, or Repeat Diagnosis Among Males Including non-Men Who Have Sex With Men: What Is the Incidence?

BACKGROUND: The release of the first drug for human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) in 2012 marked the beginning of a new era of HIV prevention. Although PrEP is highly efficacious, identifying and ultimately increasing uptake among the highest risk male subgroups remains a challenge. METHODS: Public health surveillance data from 2009 to 2016 was used to evaluate the risk of an HIV diagnosis after a syphilis (ie, primary, secondary, or early latent), gonorrhea, and repeat diagnoses among urban males, including men who have sex with men (MSM) and non-MSM in Baltimore City. RESULTS: Of the 1531 males with 898 syphilis diagnoses and 1243 gonorrhea diagnoses, 6.8% (n = 104) were subsequently diagnosed with HIV. Within 2 years, 1 in 10 syphilis or gonorrhea diagnoses were followed by an HIV diagnosis among MSM, and 1 in 50 syphilis or gonorrhea diagnoses were followed by an HIV diagnosis among non-MSM. Among non-MSM with gonorrhea, the rate of HIV incidence was 5.36 (95% confidence interval, 2.37-12.14) times higher in those with (vs. without) a subsequent syphilis diagnosis or gonorrhea diagnosis. CONCLUSIONS: Local health care providers should offer PrEP to MSM diagnosed with syphilis or gonorrhea and to non-MSM with a previous gonorrhea diagnosis at time of a syphilis or gonorrhea diagnosis. The high proportion and short time to an HIV diagnosis among MSM after a syphilis or gonorrhea diagnosis suggest immediate PrEP initiation.

Evaluation of an Adapted Project Connect Community-based Intervention Among Professionals Serving Young Minority Men.

BACKGROUND: To address sexual and reproductive health (SRH) needs of young minority urban males, we developed and evaluated Project Connect Baltimore (Connect), which was adapted from a program with demonstrated effectiveness among young females. The objectives were to determine (1) the feasibility of Connect as adapted for young minority men, (2) whether the program increased SRH knowledge and resource sharing of youth-serving professionals (YSPs) working with young men, and (3) whether the program improved awareness and use of resources for young minority men in Baltimore City, an urban environment with high rates of sexually transmitted diseases. METHODS: Connect developed a clinic referral guide for male youth-friendly resources for SRH. The YSPs working with partners and organizations serving young minority men were trained to use Connect materials and pretraining, immediate, and 3-month posttraining surveys were conducted to evaluate program effects. A before-after evaluation study was conducted among young men attending five urban Connect clinics where sexually transmitted disease/human immunodeficiency virus rates are high, recruiting young men in repeated cross-sectional surveys from April 2014 to September 2017. RESULTS: Two hundred thirty-five YSPs were trained to use Connect materials, including a website, an article-based pocket guide, and were given information regarding SRH for young men. These professionals demonstrated increased knowledge about SRH for young men at immediate posttest (60.6% to 86.7%, P < 0.05), and reported more sharing of websites for SRH (23% to 62%, P < 0.05) from pretraining to 3-month posttraining. 169 young minority men were surveyed and reported increased awareness of Connect over 3 and a half years (4% to 11%, P = 0.015), although few young men reported using the website to visit clinics. CONCLUSIONS: Project Connect Baltimore increased knowledge of SRH needs among youth-serving professionals and sharing of SRH resources by these professionals with young men. This program also demonstrated increases in awareness of SRH resources among young minority urban men.

Methods for Evaluating the Association Between Alcohol Outlet Density and Violent Crime.

BACKGROUND: The objective of this analysis was to compare measurement methods-counts, proximity, mean distance, and spatial access-of calculating alcohol outlet density and violent crime using data from Baltimore, Maryland. METHODS: Violent crime data (n = 11,815) were obtained from the Baltimore City Police Department and included homicides, aggravated assaults, rapes, and robberies in 2016. We calculated alcohol outlet density and violent crime at the census block (CB) level (n = 13,016). We then weighted these CB-level measures to the census tract level (n = 197) and conducted a series of regressions. Negative binomial regression was used for count outcomes and linear regression for proximity and spatial access outcomes. Choropleth maps, partial R2 , Akaike's Information Criterion, and root mean squared error guided determination of which models yielded lower error and better fit. RESULTS: The inference depended on the measurement methods used. Eight models that used a count of alcohol outlets and/or violent crimes failed to detect an association between outlets and crime, and 3 other count-based models detected an association in the opposite direction. Proximity, mean distance, and spatial access methods consistently detected an association between outlets and crime and produced comparable model fits. CONCLUSIONS: Proximity, mean distance, and spatial access methods yielded the best model fits and had the lowest levels of error in this urban setting. Spatial access methods may offer conceptual strengths over proximity and mean distance. Conflicting findings in the field may be in part due to error in the way that researchers measure alcohol outlet density.

Childbearing Motivations and Desires, Fertility Beliefs, and Contraceptive Use among Urban African-American Adolescents and Young Adults with STI Histories.

This study explored the influence of STI history on childbearing motivations, fertility beliefs, current childbearing desires, and contraception use among urban African-American adolescents and young adults (AYA). Secondary data were from the Neighborhood Influences on Adolescent and Young Adult Health (NIAAH) study, conducted from 2004 to 2007. Sample included 517 AYA ages 15-24 years (male: n = 199, female: n = 318). Linear and logistic regression models examined gender differences in childbearing motivations (CBM) and desires, fertility beliefs, condom, and contraception use. Logistic regression models were constructed to examine age, pregnancy history, and STI fertility knowledge as potential confounders. AYA men (3.29) and AYA women (3.23) had similar CBM mean scores. AYA women had more positive CBM and used condoms less. Condom use was not associated with CBM among AYA men (OR = 0.71, p = 0.069). Low beliefs about fertility (OR = 0.52, p = 0.003) and prior pregnancy (OR = 5.27, p = 0.002) were associated with current childbearing desires among AYA women. AYA men's low fertility beliefs were only associated with current childbearing desires (OR = 0.56, p = 0.044). AYA men reported more contraception use (67.46 vs. 55.04%), especially with no partner pregnancy history (OR = 0.26, p = 0.017). Younger men (15 to 18 years old) reported more contraception or condom use compared to older AYA men (19-25 years old) (OR = 0.40, p = 0.016). Young men reporting a partner's prior pregnancy used fewer condoms or contraception (OR = 0.23, p = 0.028). STI history did not influence CBM in this sample of urban youth. Prior pregnancy experiences and chronological age, however, were important milestones shaping proximal motivations and desires to bear children, beliefs about fertility, and contraception behaviors.
