Placental miR-3940-3p Is Associated With Maternal Insulin Resistance in Late Pregnancy.

CONTEXT: An increase in maternal insulin resistance (IR) during pregnancy is essential for normal fetal growth. The mechanisms underlying this adaptation are poorly understood. Placental factors are believed to instigate and maintain these changes, as IR decreases shortly after delivery. Methylation of placental gene loci that are common targets for miRNAs are associated with maternal IR. OBJECTIVE: We hypothesized that placental miRNAs targeting methylated loci are associated with maternal IR during late pregnancy. METHODS: We collected placentas from 132 elective cesarean sections and fasting blood samples at delivery to estimate maternal homeostasis model assessment of insulin resistance (HOMA-IR). Placental miRNA expression was measured via whole genome small-RNA sequencing in a subset of 40 placentas selected by maternal pre-gravid body mass index (BMI) and neonatal adiposity. Five miRNAs correlated with maternal HOMA-IR and previously identified as targeting methylated genes were selected for validation in all 132 placenta samples via RT-qPCR. Multiple regression adjusted for relevant clinical variables. RESULTS: Median maternal age was 27.5 years, with median pre-pregnancy BMI of 24.7 kg/m2, and median HOMA-IR of 2.9. Among the 5 selected miRNA, maternal HOMA-IR correlated with the placental expression of miRNA-371b-3p (r = 0.25; P = 0.008) and miRNA-3940-3p (r = 0.32; P = 0.0004) across the 132 individuals. After adjustment for confounding variables, placental miRNA-3940-3p expression remained significantly associated with HOMA-IR (ß = 0.16; P = 0.03). CONCLUSION: Placental miRNA-3940-3p was associated with maternal IR at delivery. This placental miRNA may have an autocrine or paracrine effect-regulating placental genes involved in modulating maternal IR.

Engaging Young Men in the HIV Prevention and Care Continua: Experiences From Young Men of Color Who Have Sex With Men.

Sexual minority individuals experience barriers to receiving equitable health care. Research also indicates that young men who have sex with men (YMSM), particularly young men of color, have limited engagement in the HIV care continuum and there are significant disparities across the continuum. This study aims to uncover how providers can engage YMSM of color in all forms of care, including primary care and HIV prevention through an HIV prevention continuum. This qualitative study reports data from the Healthy Young Men's Cohort Study; a total of 49 YMSM participated in the eight focus groups. This study provides a description of YMSM's overall health concerns, experiences with health care, and under what circumstances YMSM seek care. We then present a model describing the salient characteristics of a HIV prevention continuum for YMSM of color and provide clear areas for education, intervention, and policy change to support better overall health for YMSM of color.

A Focus on the HIV Care Continuum Through the Healthy Young Men's Cohort Study: Protocol for a Mixed-Methods Study.

BACKGROUND: No group is at greater risk for acquiring HIV than young men who have sex with men (YMSM), particularly black or African American (AA) and Hispanic or Latino (L) YMSM living in inner cities, who account for the largest number of new HIV infections each year. Although pre-exposure prophylaxis (PrEP), postexposure prophylaxis (PEP), and treatment as prevention hold enormous promise for changing the course of the epidemic, AA/L-YMSM are the least likely population to be receiving primary health care and HIV prevention/care and are the least likely to be using PrEP and PEP. OBJECTIVE: The overarching aim of the Healthy Young Men's (HYM) cohort study is to conduct longitudinal research with a cohort of AA/L-YMSM to prevent new HIV infections, reduce transmission, and reduce HIV/AIDS-related disparities by focusing on successful engagement in care. Findings from this research will be used to inform the development of new interventions designed to engage AA/L-YMSM in the HIV prevention and care continua. METHODS: Longitudinal research (baseline and follow-up assessments every 6 months for a total of 8 waves of data collection) is ongoing with a new cohort of 450 high-risk AA/L-YMSM in Los Angeles. Participants were recruited using a venue-based and social media sampling design. In addition to self-report surveys, the study protocol includes the collection of urine to assess recent use of illicit drugs and the collection of blood and rectal/throat swabs to test for current sexually transmitted infection (STI)/HIV infection. An additional sample of blood/plasma (10 mL for 4 aliquots and 1 pellet) is also collected and stored in the HYM cohort study biorepository for future research. By design, we recruited 400 HIV-negative participants and 50 HIV-positive (HIV+) participants. This mixed-methods study design includes collection and triangulated analysis of quantitative, qualitative, and biological measures (ie, drug use, STI/HIV testing, and adherence to antiretroviral therapy among HIV+ participants) at baseline and every 6 months. The HYM cohort study will provide a platform from which new and emerging biomedical prevention strategies (eg, PrEP, rectal microbicides, and PEP) and other HIV prevention and care engagement interventions can be developed and evaluated with AA/L-YMSM. RESULTS: To date, all participants in the HYM cohort study have been recruited and baseline assessment has been conducted. CONCLUSIONS: The findings from this research will be used to inform the development of new and/or adaptation of existing evidence-based HIV prevention interventions and interventions designed to engage this population in the HIV prevention and care continua.

Preventing Filipino Mental Health Disparities: Perspectives from Adolescents, Caregivers, Providers, and Advocates.

Filipino Americans are the second largest immigrant population and second largest Asian ethnic group in the U.S. Disparities in youth behavioral health problems and the receipt of mental health services among Filipino youth have been documented previously. However, few studies have elicited perspectives from community stakeholders regarding how to prevent mental health disparities among Filipino youth. The purpose of the current study is to identify intervention strategies for implementing mental health prevention programs among Filipino youth. We conducted semi-structured interviews (n=33) with adolescents, caregivers, advocates, and providers and focus groups (n=18) with adolescents and caregivers. Interviews were audio taped and transcribed verbatim. Transcripts were analyzed using a methodology of "coding consensus, co-occurrence, and comparison" and was rooted in grounded theory. Four recommendations were identified when developing mental health prevention strategies among Filipino populations: address the intergenerational gap between Filipino parents and children, provide evidence-based parenting programs, collaborate with churches in order to overcome stigma associated with mental health, and address mental health needs of parents. Findings highlight the implementation of evidence-based preventive parenting programs in faith settings as a community-identified and culturally appropriate strategy to prevent Filipino youth behavioral health disparities.

Community-engaged research to identify house parent perspectives on support and risk within the House and Ball scene.

This article describes a community-engaged study with the Los Angeles House and Ball scene in which the perspectives of the leaders of these communities are captured to better understand how the House and Ball communities may protect or increase its members' risks for HIV infection. Data were collected through in-depth interviews with House parents (N = 26). This study identified key features of both support (e.g., family and support, acceptance, and validation and recognition) and risk (e.g., members' struggles to maintain status in the Ballroom scene, sex work, substance use, danger of becoming too involved in the Ball community, and perception and stigma of the Ballroom scene within the larger gay community) within these communities. Findings are discussed in relation to framing how to leverage the supportive aspects of the House and Ball communities to design relevant HIV-prevention interventions.

Photovoice as a tool to adapt an HIV prevention intervention for African American young men who have sex with men.

Objective. HIV rates for African American young men who have sex with men (AAYMSM) have reached as much as 14.7%, compared with 2.5% and 3.5% among Caucasian and Latino YMSM. However, there remains a lack of HIV prevention interventions for this population. This study describes the use of Photovoice in the adaptation process of an evidence-based intervention (Adult Identity Mentoring) to make it developmentally and culturally appropriate for AAYMSM. Method. A total of 36 AAYMSM (aged 18-24 years) participated in weekly working group sessions to conduct a community-, youth-, and data-driven adaptation process. Photovoice was used as a technique to facilitate guided discussions on topics that were identified for the new curriculum. Results. Through Photovoice discussions, we identified a new focus for the adapted intervention, Young Men's Adult Identity Mentoring (YM-AIM): development and maintenance of healthy intimate relationships. This new focus and the resulting curriculum are rooted in the voices and perceptions of the target population. Conclusions. Including youth was integral to the adaptation process and the use of techniques such as Photovoice helped ensure that the resulting adaptation was relevant to the target population.

In the dark: young men's stories of sexual initiation in the absence of relevant sexual health information.

A growing body of research has investigated the effectiveness of abstinence-only sexual education. There remains a dearth of research on the relevant sexual health information available to young men who have sex with men (YMSM). Drawing on a mixed-methods study with 526 YMSM, this study explores how and where YMSM receive relevant information on sexual health/behavior. Findings indicate that information related to gay men's sexuality is not readily available from family, friends, or schools. At initiation of anal intercourse, respondents generally had limited information about HIV and sexually transmitted infections (STIs). In some cases, this resulted in the perception that activities such as unprotected sex were "low risk." Many mentioned they first learned about anal sex during their sexual debut, describing painful and/or unpleasant experiences. Some relied on older/more experienced partners, the Internet, and pornography for information. Findings are discussed in relation to how providers can help YMSM build solid foundations of sexual education to protect them from STI and HIV infection.
