An Integrated Intervention to Reduce HIV Risk Behaviors Among Heterosexual HIV-Negative, African American Couples: Pilot Feasibility, Acceptability, and Usefulness Study.

Synergistic interactions between substance use and violence (SAVA syndemic) are strongly associated with heightened risk for HIV acquisition in the African American population. While couple-based interventions have shown efficacy among at-risk and HIV-positive serodiscordant couples, no interventions have specifically targeted SAVA syndemic risk reduction for HIV-negative, high-risk, heterosexual African American couples in the United States. This pilot study tested the feasibility, safety, and preliminary effects of an integrated sexual risk reduction intervention for African American couples.

Exploring Psychosocial and Structural Syndemic Effects as Predictors of HIV Risk Behaviors Among Black Women (HPTN 064).

Syndemic models have been used in previous studies exploring HIV-related outcomes; however, these models do not fully consider intersecting psychosocial (, substance use, depressive symptoms) and structural factors (unstable housing, concentrated housing vacancy) that influence the lived experiences of women. Therefore, there is a need to explore the syndemic effects of psychosocial and structural factors on HIV risk behaviors to better explain the multilevel factors shaping HIV disparities among black women. This analysis uses baseline data (May 2009-August 2010) from non-Hispanic black women enrolled in the HIV Prevention Trials Network 064 Women's Seroincidence Study (HPTN 064) and the American Community Survey 5-year estimates from 2007 to 2011.

These nanostructures comprise block copolymer (BCP) micelles, containing a single gold nanoparticle (AuNP) in the core and multiple photoluminescent cadmium selenide (CdSe) quantum dots (QDs) attached to the micelle's coronal chains. The asymmetric polystyrene--poly(4-vinylpyridine) (PS--P4VP) BCP was employed to develop these core-satellite nanostructures in a series of P4VP-selective alcoholic solvents.

A Meta-Analysis and Systematic Review of Community-Based Intimate Partner Violence Interventions in India.

Intimate partner violence (IPV) in India remains an entrenched and prevalent public health issue. Despite ample evidence of the widespread problem of IPV in India and associated mental and physical morbidities, far less is known about intervention models to reduce IPV in India. The aims of this meta-analysis and systematic review are to assess the effectiveness of community-based interventions to reduce IPV in India and to provide a narrative synthesis of these intervention approaches.

Examining HIV Diagnosis and Linkage to PrEP Prescription Among Members at An Integrated Health System in the Southeast United States.

Pre-Exposure Prophylaxis (PrEP) is a priority method for preventing HIV infection. This study's aims were threefold: (1) identify characteristics of members of a large health maintenance organization, Kaiser Permanente Georgia (KPGA), associated with HIV infection, (2) identify which member characteristics associated with HIV were also associated with PrEP prescription, and (3) identify which HIV-associated characteristics were associated with under- or over-prescribing of PrEP. Analysis of variables from the electronic medical record revealed that age, race, gender, mental health diagnosis, STI diagnosis, and sexual orientation were independently associated with HIV diagnosis.

Sexual Risk Behavior and Lifetime HIV Testing: The Role of Adverse Childhood Experiences.

Despite the success of HIV prevention drugs such as PrEP, HIV incident transmission rates remain a significant problem in the United States. A life-course perspective, including experiences of childhood adversity, may be useful in addressing the HIV epidemic. This paper used 2019 BRFSS data to elucidate the role that childhood adversity plays in the relationship between HIV risk and HIV testing.

Insight into morphology dependent charge carrier dynamics in ZnSe-CdS nanoheterostructures.

Semiconductor nanoheterostructures (NHSs) are being increasingly used for the photocatalytic conversion of solar energy in which photo-induced charge separation is an essential step and hence it is necessary to understand the effect of various factors such as size, shape, and composition on the charge transfer dynamics. Ultrafast transient absorption spectroscopy is used to investigate the nature and dynamics of photo-induced charge transfer processes in ZnSe-CdS NHSs of different morphologies such as nanospheres (NSs), nanorods (NRs), and nanoplates (NPs). It demonstrates the fast separation of charge carriers and localization of both charges in adjacent semiconductors, resulting in the formation of a charge-separated (CS) state.

Influence of Framing: Recruitment to a Diabetes Disease Management Program From an Emergency Department Improves Enrollment and Outcomes.

Introduction Disease management programs (DMPs) provide education, self-management skills, care coordination, and frequent clinical assessment and medication adjustment. Our health system's diabetes mellitus (DM) DMP recruited patients from an emergency department (ED) and outpatient settings (primary care physicians' [PCP] and endocrinologists' offices; cold calling patients with poorly-controlled diabetes). We investigated whether recruitment to a DMP from an ED is feasible and effective, hypothesizing such patients would have better enrollment rates, future A1c control, and ED utilization because their receptiveness to change was "framed" by their ED visit.

Safer Sex Self-Efficacy Among Women With Experiences of Intimate Partner Violence.

Women who have experienced intimate partner violence (IPV) are more likely to engage in risky sexual behaviors that increase the likelihood of adverse sexual health outcomes, including HIV acquisition. This study explored key predictors of safer sex self-efficacy in a sample of racially/ethnically diverse abused women. A total of 173 women were recruited from domestic violence agencies and completed a battery of measures that assessed risk factors associated with HIV risk.

Recent Partner Violence, Sexual Relationship Power, and STIs among Women Who Use Methamphetamine: Does Type of Sexual Partner Matter?

Methamphetamine use, sexual relationship power (SRP), and partner violence (PV) are associated with increased risk of sexually transmitted infections (STIs) among women. The objective of our study was to examine the association of recent PV and SRP on STIs by partner type among HIV-negative, heterosexual women who use methamphetamine in San Diego, CA. Using baseline survey data from 209 women enrolled in FASTLANE II, an HIV behavioral intervention trial, we conducted logistic regression analyses to examine associations between PV, SRP, and self-reported lifetime STIs (e.

Enhanced Photocurrent Owing to Shuttling of Charge Carriers across 4-Aminothiophenol-Functionalized MoSe-CsPbBr Nanohybrids.

Mixed-dimensional van der Waals nanohybrids (MvNHs) of two-dimensional transition-metal dichalcogenides (TMDs) and zero-dimensional perovskites are highly promising candidates for high-performance photonic device applications. However, the growth of perovskites over the surface of TMDs has been a challenging task due to the distinguishable surface chemistry of these two different classes of materials. Here, we demonstrate a synthetic route for the design of MoSe-CsPbBr MvNHs using a bifunctional ligand, i.

Intimate Partner Violence and Effectiveness Level of Contraceptive Selection Post-Abortion.

We examined whether experiencing more types of lifetime intimate partner violence (IPV) was independently associated with the effectiveness level of the contraceptive method women chose following an abortion. Using data on 245 women who were attending an urban hospital abortion clinic, we assessed whether women had ever experienced emotional, physical, or sexual IPV. Effectiveness of women's post-abortion contraceptive method selection was categorized into high (intrauterine device [IUD] and implant), moderate (pill, patch, ring, and shot), and low (condoms, emergency contraception, and none) effectiveness.

Fluorescence resonance energy transfer in multifunctional nanofibers designed via block copolymer self-assembly.

In the present study, we demonstrate the fabrication of multifunctional nanofibers, loaded with CdSe quantum dots (QDs) and sulforhodamine 101 (S101) dye, via the self-assembly process of a polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) block copolymer (BCP). The CdSe QDs and S101 dye were simultaneously incorporated in the cylindrical domains, constituted of P4VP blocks, of the self-assembled BCP structure. The cylindrical domains subsequently were isolated as individual nanofibers via the selective-swelling approach.

Examining Associations Between Strangulation and Depressive Symptoms in Women With Intimate Partner Violence Histories.

Intimate partner violence (IPV) is associated with poor mental health outcomes among women. Studies on IPV and mental health show that experiencing more than one type of IPV often enhances women's depression or depressive symptoms. However, most of these studies conceptualize IPV as physical, psychological, or sexual violence.
