Abstract
OBJECTIVE Trauma, violence, and their consequences for population health are shaped by complex, intersecting forces across the life span. We aimed to illustrate the strengths of agent-based modeling (ABM), a computational approach in which population-level patterns emerge from the behaviors and interactions of simulated individuals, for advancing trauma research; Method: We provide an overview of agent-based modeling for trauma research, including a discussion of the model development process, ABM as a complement to other causal inference and complex systems approaches in trauma research, and past ABM applications in the trauma literature; Results: We use existing ABM applications to illustrate the strengths of ABM for trauma research, including incorporating interactions between individuals, simulating processes across multiple scales, examining life-course effects, testing alternate theories, comparing intervention strategies in a virtual laboratory, and guiding decision making. We also discuss the challenges of applying ABM to trauma research and offer specific suggestions for incorporating ABM into future studies of trauma and violence; Conclusion: Agent-based modeling is a useful complement to other methodological advances in trauma research. We recommend a more widespread adoption of ABM, particularly for research into patterns and consequences of individual traumatic experiences across the life course and understanding the effects of interventions that may be influenced by social norms and social network structures.

Kroch A, O’Byrne P, Orser L, MacPherson P, O’Brien K, Light L, Kang R, Nyambi A. Increased PrEP uptake and PrEP-RN coincide with decreased HIV diagnoses in men who have sex with men in Ottawa, Canada. CANADA COMMUNICABLE DISEASE REPORT = RELEVE DES MALADIES TRANSMISSIBLES AU CANADA 2023; 49:274-281.

Abstract
Background We sought to evaluate if increased uptake of HIV pre-exposure prophylaxis (PrEP) correlated to population-level changes in human immunodeficiency virus (HIV) epidemiology, in a setting with an integrated PrEP delivery system centred on a public health nurse-led PrEP clinic and referral process. Methods This study was conducted in Ottawa, Canada, where all positive HIV test results are reported to the public health units. Risk factor information is also collected by nurses and subsequently entered into a provincial database. We extracted these data for Ottawa from 2017 to 2021 and restricted our analyses to first-time diagnoses. Results We identified 154 persons with a new HIV diagnosis. Over this period, the number of new diagnoses among men who have sex with men, the group most targeted for PrEP, decreased by 50%-60%. We did not identify changes in the number of new diagnoses based on race, intravenous drug use or among women. Conclusion Increasing PrEP uptake in Ottawa in 2017 to 2021 coincided with a significant decrease in new HIV diagnoses among men who have sex with men. PrEP uptake in Ottawa, particularly by those most at risk, is likely supported by an integrated approach via PrEP-RN, a nurse-led public health program where individuals diagnosed with syphilis or rectal gonorrhea or chlamydia receive an automatic offer of PrEP. While these findings cannot causally link PrEP-RN or PrEP with this reduction in new HIV diagnoses, these changes in HIV epidemiology in Ottawa occurred exclusively among the group targeted for PrEP. These data highlight the efficacy and importance of PrEP.

Abstract
PURPOSE Women involved in the carceral system (CS) experience several conditions that increase their risk for HIV (e.g. high rates of substance use, psychiatric disorders, histories of victimization). The purpose of this study is to explore perspectives on potential strategies to connect women in the CS to pre-exposure prophylaxis (PrEP) services. DESIGN/METHODOLOGY/APPROACH This study conducted in-depth interviews with 27 women involved in the CS eligible for PrEP. Using vignettes, interviews explored attitudes, barriers and facilitators toward PrEP screening, referral and linkage facilitated via a CS stakeholder, an mHealth application or providing PrEP service referrals during detention via a navigator. FINDINGS Most women were, on average, 41.3 years, from racial and ethnic minority groups (56% black/African American; 19% Latinx). Inductive thematic analysis revealed CS involved women expressed mostly positive attitudes toward CS-based PrEP implementation. Younger women were more accepting of and interested in mHealth interventions. Implementation facilitators included leveraging relationships with trusted allies (e.g. "peers") and existing systems collaborations. Recommended implementation strategies included providing HIV and PrEP-specific education and training for system stakeholders and addressing issues related to privacy, system mistrust and stigma. ORIGINALITY/VALUE Results provide a critical foundation for the implementation of interventions to improve PrEP access for women involved in the CS and have important implications for implementation strategies for all adults involved in the CS. Improving access to PrEP among this population may also support progress toward addressing national disparities in PrEP uptake, where women, black and Latinx populations have substantial unmet need.

Abstract
HIV remains a significant public health concern for Black adults (BA) in the United States. Pre-exposure prophylaxis (PrEP) is a highly effective prevention tool prescribed to protect the health of HIV-uninfected individuals. Yet, low rates of PrEP awareness and utilization persist among BA. Less is understood about the pathways that may promote PrEP uptake. The present study explored factors associated with PrEP awareness and use among BA. Using a cross-sectional sample of 666 BA, we employed multivariable logistic regression models to examine the relationship between PrEP and several covariates. Most participants were unaware of PrEP (71%). Reporting history of incarceration and lifetime sexually transmitted infection testing [aOR 1.76 (1.19, 2.59), p < 0.05] had greater odds of PrEP awareness. Only 6% of respondents had ever taken PrEP. Reports of incarceration history [aOR 9.96 (2.82, 35.14), p < 0.05], concurrent sexual partners [aOR 1.09 (1.00, 1.18), p < 0.05], and substance use during sex [aOR 4.23 (1.02, 17.48), p < 0.05] had greater odds of PrEP use. Interventions aiming to improve PrEP uptake among BA must consider the individual, social, and structural contexts associated with its awareness and use. Enhanced efforts by healthcare providers and institutions may better facilitate access to PrEP for HIV prevention and control transmission.

WOMEN'S HEALTH (LONDON, ENGLAND) 2022; 18:17455057221103098. [PMID: 35699104 PMCID: PMC9201306 DOI: 10.1177/17455057221103098] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 04/28/2022] [Accepted: 05/06/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND Black cisgender women in the United States experience a disproportionate burden of human immunodeficiency virus acquisition. Pre-exposure prophylaxis is an effective oral daily medication that reduces the risk of human immunodeficiency virus through sex by 99% when taken as prescribed. However, less than 2% of eligible Black cisgender women take pre-exposure prophylaxis. The purpose of this scoping review was to describe the types of research studies done in this area, gaps in knowledge, and potential areas of research needed to increase pre-exposure prophylaxis use among Black cisgender women in the United States. METHODS We conducted our search in MEDLINE (PubMed), Embase (Elsevier), CINAHL (EBSCOhost), PsycINFO (EBSCOhost), and Scopus (Elsevier) using a combination of keywords and database-specific subject headings for the following concepts: pre-exposure prophylaxis, African American/Black or minority, and women. We used the Joanna Briggs Institute's Reviewers' Manual process for Scoping Reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews to ensure comprehensive and standardized reporting of each part of the review. RESULTS Fifty-nine studies were included in the final review. Results of the study were classified according to the three phases of the Human Immunodeficiency Virus Prevention Cascade-demand side, supply side, and adherence and retention. The majority of studies (n = 24, 41%) were cross-sectional quantitative surveys and 43 (34%) focused on the demand-side phase of the Human Immunodeficiency Virus Prevention Cascade. Fifty-eight percent of studies either assessed women's pre-exposure prophylaxis knowledge, attitudes, and intentions to use, or assessed perceived barriers and facilitators. Seven studies (12%) tested pre-exposure prophylaxis uptake and adherence among Black cisgender women. CONCLUSION This review found multiple missed opportunities to increase women's demand for pre-exposure prophylaxis and health care provider screening and referral for pre-exposure prophylaxis. Additional studies are needed to effectively assess pre-exposure prophylaxis uptake and adherence among Black cisgender women.
