Objectives: To eliminate vertical transmission of HIV, global institutions recommend using a risk-guided approach for HIV prevention services in antenatal and postnatal settings. Identifying predictors of maternal HIV acquisition can inform the development of risk-guided approaches, but individual studies of predictors can have limited power and generalizability. Methods: We conducted a systematic review and narrative synthesis to identify common predictors of maternal HIV acquisition in sub-Saharan Africa (SSA). We searched four databases for full-text articles that estimated associations between at least one predictor and risk of HIV acquisition among pregnant and/or lactating women (PLW) in SSA. We restricted our synthesis to predictors assessed in at least four study populations. For these predictors, we summarized how each predictor was defined and used vote counting and descriptive statistics to characterize overall trends. Results: We identified 26 eligible publications that summarized results from 24 unique studies. Studies were implemented in 12 countries between 1988 and 2021 and enrolled a total of 164,480 PLW at risk of acquiring HIV. Of the 66 predictors evaluated, 16 met our inclusion criteria. Estimated associations tended to be imprecise and variability in how predictors were measured precluded meta-analyses. We observed trends towards a higher risk of maternal HIV acquisition among young women and women who reported early coital debut, multiple partnerships, sexually transmitted infections, being unaware of partner HIV status, or having a partner living with HIV. In most studies, PLW in stable, monogamous relationships experienced a lower risk of acquiring HIV than those who were single, separated, or in a polygynous marriage. HIV risk perception, condom use, and vaginal drying were also commonly associated with HIV acquisition risk. Conclusions: In our systematic review and narrative synthesis, we identified several easily measured characteristics that were associated with HIV acquisition among PLW in multiple study populations across SSA. Such findings can support the development and refinement of risk-guided approaches for HIV prevention in the region. [ABSTRACT FROM AUTHOR]

Introduction: Despite widespread success in reducing vertical HIV transmission, most antenatal care (ANC) programmes in eastern and southern Africa have not emphasized primary prevention of maternal HIV acquisition during pregnancy and lactation/breastfeeding. We hypothesized that combination HIV prevention interventions initiated alongside ANC could substantially reduce maternal HIV incidence. Methods: We constructed a multi‐state model describing male‐to‐female HIV transmission in steady heterosexual partnerships during pregnancy and lactation/breastfeeding, with initial conditions based on population distribution estimates for Malawi and Zambia in 2020. We modelled individual and joint increases in three HIV prevention strategies at or soon after ANC initiation: (1) HIV testing of male partners, resulting in HIV diagnosis and less condomless sex among those with previously undiagnosed HIV; (2) initiation (or re‐initiation) of suppressive antiretroviral therapy (ART) for male partners with diagnosed but unsuppressed HIV; and (3) adherent pre‐exposure prophylaxis (PrEP) for HIV‐negative female ANC patients with HIV‐diagnosed or unknown‐status male partners. We estimated the percentage of within‐couple, male‐to‐female HIV transmissions that could be averted during pregnancy and lactation/breastfeeding with these strategies, relative to base‐case conditions in which 45% of undiagnosed male partners become newly HIV diagnosed via testing, 75% of male partners with diagnosed but unsuppressed HIV initiate/re‐initiate ART and 0% of female ANC patients start PrEP. Results: Increasing uptake of any single strategy by 20 percentage points above base‐case levels averted 10%−11% of maternal HIV acquisitions during pregnancy and lactation/breastfeeding in the model. Joint uptake increases of 20 percentage points in two interventions averted an estimated 19%−23% of transmissions, and with a 20‐percentage‐point increase in uptake of all three interventions, 29% were averted. Strategies achieving 95% male testing, 90% male ART initiation/re‐initiation and 40% female PrEP use reduced incident infections by 45%. Conclusions: Combination HIV prevention strategies provided alongside ANC and sustained through the post‐partum period could substantially reduce maternal HIV incidence during pregnancy and lactation/breastfeeding in eastern and southern Africa.

Introduction: Couple HIV testing and counselling (CHTC) is associated with measurable benefits for HIV prevention and treatment. However, the uptake remains limited in much of sub‐Saharan Africa, despite an expanded range of strategies designed to promote access. Methods: Following PRIMSA guidelines, we conducted a systematic review to characterize CHTC uptake strategies. Five databases were searched. Full‐text articles were included if they were: conducted in sub‐Saharan Africa during the study period (1980–2019), targeted heterosexual couples, reported at least one strategy to promote CHTC and provided a quantifiable measure of CHTC uptake. After the initial and full‐text screening, key features of the studies were abstracted and synthesized. Results: Of the 6188 unique records found in our search, 365 underwent full‐text review with 29 distinct studies included and synthesized. Most studies recruited couples through antenatal care (n = 11) or community venues (n = 8) and used provider‐based HIV testing (n = 25). The primary demand creation strategies included home‐based CHTC (n = 7); integration of CHTC into clinical settings (n = 4); distribution of HIV self‐testing kits (n = 4); verbal or written invitations (n = 4); community recruiters (n = 3); partner tracing (n = 2); relationship counselling (n = 2); financial incentives (n = 1); group education with CHTC coupons (n = 1); and HIV testing at other community venues (n = 1). CHTC uptake ranged from negligible to nearly universal. Discussion: We thematically categorized a diverse range of strategies with varying levels of intensity and resources used across sub‐Saharan Africa to promote CHTC. Offering CHTC within couples' homes was the most common approach, followed by the integration of CHTC into clinical settings. Due to heterogeneity in study characteristics, we were unable to compare the effectiveness across studies, but several trends were observed, including the high prevalence of CHTC promotion strategies in antenatal settings and the promising effects of home‐based CHTC, distribution of HIV self‐tests and integration of CHTC into routine health services. Since 2019, an updated literature search found that combining partner notification and secondary distribution of HIV self‐test kits may be an additionally effective CHTC strategy. Conclusions: There are many effective, feasible and scalable approaches to promote CHTC that should be considered by national programmes according to local needs, cultural context and available resources.

This study explored the experiences of pregnant women who received two intervention models for increasing uptake of male partner HIV testing in antenatal settings. As part of a randomised trial, we interviewed twenty participants who received partner notification services only while 22 received the partner notification plus HIV self-testing. Thematic analysis was used to analyse the data. Partner notification services helped to initiate discussions of HIV testing with partners, influence partners to undergo testing, and encouraged disclosure of HIV status. Some women experienced difficulties engaging partners due to fear of their partner's reaction. Some partners were unable to test due to time constraints. The partner notification plus HIV self-testing intervention, stimulated discussion about HIV testing; facilitated testing for men at their convenience; addressed privacy/confidentiality, and stigma concerns; and provided the opportunity to disclose HIV status. Some women feared disclosure and retribution in case of discordance results. There were also challenges with men making follow-ups for confirmatory HIV tests. The addition of HIV self-test kits to partner notification services can expand HIV testing services to male partners, including those of HIV-negative women. Additional efforts are needed to link men to appropriate HIV prevention, care, and treatment services. [ABSTRACT FROM AUTHOR]

This study sought to explore and contextualise the man's role in antenatal services, and the barriers and strategies for engaging men in prevention of mother-to-child HIV transmission (PMTCT). We conducted 143 interviews with pregnant and breastfeeding women, male partners, health workers and policy makers in Malawi and Zambia. We employed thematic and critical discourse analysis using the hegemonic masculinity perspective. We found that men's roles in PMTCT reflected hegemonic masculinities. As breadwinners, men supported their partners with material and financial resources. As decision makers, men were involved in decision making on the health of their partners. As social protectors, men supported their partners in accessing and adhering to antenatal care, HIV treatment and care. Barriers and challenges to male involvement in antenatal care were often the result of conflict between the clinic operating hours and men's working hours, the perception of antenatal care services as female spaces, and men's fear of HIV testing. Proposed strategies to increase male engagement in PMTCT included sensitising men about HIV and pregnancy; engaging leaders and employers, providing services outside working hours, and providing incentives. We conclude that men's role and participation in PMTCT services are an extension and adaptation of hegemonic masculinities. [ABSTRACT FROM AUTHOR]

To eliminate mother-to-child transmission of HIV (EMTCT), scalable strategies to enhance antiretroviral adherence for both antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) are needed as part of integrated HIV and maternal-child health services. We developed Tonse Pamodzi ("all of us together"), an adaptable intervention integrating biomedical and behavioral components to support HIV treatment and prevention. We describe our intervention development process, which comprised formative qualitative research, a review of the literature, and technical input from stakeholders representing the community, health systems, and policymakers. The resulting intervention, described herein, integrates patient-centered counseling and engagement of a patient-selected adherence supporter for pregnant and breastfeeding women initiating ART or PrEP. Patients receiving the intervention engage in Integrated Next Step Counseling (iNSC) sessions delivered by trained counselors to build and maintain adherence skills. Each patient also has the option of selecting an adherence supporter (partner, family member, or friend) who may participate in iNSC sessions and provide adherence support outside of these sessions. This flexible intervention is adaptable not only to ART or PrEP use, but also to the needs and preferences of each woman and the clinical context. If shown to be acceptable and feasible, the Tonse Pamodzi intervention may be an important tool in continuing efforts for EMTCT. [ABSTRACT FROM AUTHOR]

The CDC recommends PrEP for MSM at substantial risk of HIV acquisition, leaving clinicians unsure whether to prescribe PrEP to MSM who do not disclose HIV risk factors. A longitudinal cohort of MSM requesting PrEP despite reporting during a clinical visit either 100% condom use or participation in oral sex only and no other risk factors was followed over 13 months at a community clinic in San Francisco to assess the accuracy of their HIV risk perception. Participants completed a sexual and substance use behavior questionnaire at baseline, outside of the clinical visit and were followed by quarterly HIV/STI testing and condom use change questionnaires. Condomless sex increased from 0% at baseline to 12% at month 1, peaked at 34% at month 7, and then decreased again to 8% at month 13. Rates of pharyngeal GC/CT varied from 7% at baseline to 12% at month 13, while rectal GC/CT decreased from 6% at baseline to 0% at month 13. The rate of syphilis was 1% both at baseline and at month 13, however, 11% and 15% of clients tested positive for syphilis at months 1 and 7 respectively. [ABSTRACT FROM AUTHOR]

High HIV incidence rates have been observed among pregnant and breastfeeding women in sub-Saharan Africa. Oral pre-exposure prophylaxis (PrEP) can effectively reduce HIV acquisition in women during these periods; however, understanding of its acceptability and feasibility in antenatal and postpartum populations remains limited. To address this gap, we conducted in-depth interviews with 90 study participants in Malawi and Zambia: 39 HIV-negative pregnant/breastfeeding women, 14 male partners, 19 healthcare workers, and 18 policymakers. Inductive and deductive approaches were used to identify themes related to PrEP. As a public health intervention, PrEP was not well-known among patients and healthcare workers; however, when it was described to participants, most expressed positive views. Concerns about safety and adherence were raised, highlighting two critical areas for community outreach. The feasibility of introducing PrEP into antenatal services was also a concern, especially if introduced within already strained health systems. Support for PrEP varied among policymakers in Malawi and Zambia, reflecting the ongoing policy discussions in their respective countries. Implementing PrEP during the pregnancy and breastfeeding periods will require addressing barriers at the individual, facility, and policy levels. Multi- level approaches should be considered in the design of new PrEP programs for antenatal and postpartum populations. [ABSTRACT FROM AUTHOR]

Aims and Objectives: To review the literature regarding PrEP and sexual behaviour change in MSM. Background: Pre‐exposure prophylaxis for HIV has been available since 2012. Even so, pre‐exposure prophylaxis has not been widely accepted among healthcare providers and men who have sex with men some of whom are convinced that pre‐exposure prophylaxis decreases condom use and increases sexually transmitted infections. Design: A systematic review of the state of the evidence regarding the association of pre‐exposure prophylaxis with condom use, sexually transmitted infection incidence and change in sexual risk behaviours in men who have sex with men. A structured search of databases resulted in 142 potential citations, but only 10 publications met inclusion criteria and underwent data abstraction and critical appraisal. Methods: An adapted Cochrane Collaboration domain‐based assessment tool was used to critically appraise the methodological components of each quantitative study, and the Mixed Methods Appraisal Tool was used to critically appraise qualitative and mixed‐methods studies. Results: Condom use in men who have sex with men using pre‐exposure prophylaxis is influenced by multiple factors. Studies indicate rates of sexually transmitted infections in treatment and placebo groups were high. Pre‐exposure prophylaxis did not significantly change sexually transmitted infection rates between baseline and follow‐up. Reporting of sexual risk improved when questionnaires were completed in private by clients. Our review found that pre‐exposure prophylaxis may provide an opportunity for men who have sex with men to access sexual health care, testing, treatment and counselling services. We did not find any conclusive evidence that pre‐exposure prophylaxis users increase sexual risk behaviours. Conclusion: The perception among healthcare providers that pre‐exposure prophylaxis leads to increased sexual risk behaviours has yet to be confirmed. In order to provide effective sexual health services, clinicians need to be knowledgeable about pre‐exposure prophylaxis as an HIV prevention tool. Relevance to clinical practice: In an era where HIV prevention methods are rapidly improving, strategies for sexually transmitted infection testing, treatment, counselling and prevention remain vital to improve health. All healthcare providers are uniquely positioned to promote sexual health through the dissemination of accurate information. [ABSTRACT FROM AUTHOR]

In a community-based clinic serving men who have sex with men in San Francisco, California, this study characterized key steps of the pre-exposure prophylaxis (PrEP) cascade and identified correlates of retention in care. In total, 344 patients were evaluated for PrEP. Three-fourths (78%) of those who sought PrEP services initiated PrEP. The overall cumulative incidence of discontinuing PrEP at 13 months was 38%. Men with a sexually transmitted infection (STI) were 44% less likely to be retained (adjusted hazard ratio [aHR] 0.56, 95% confidence interval [0.33-0.95]). Comprehensive retention efforts for men with STIs are crucial to optimize the benefits of PrEP. [ABSTRACT FROM AUTHOR]

Background: The Centers for Disease Control recommend screening for asymptomatic sexually transmitted infection (STI) among HIV-infected men when there is self-report of unprotected anal-receptive exposure. The study goals were: (1) to estimate the validity and usefulness for screening policies of self-reported unprotected anal-receptive exposure as a risk indicator for asymptomatic anorectal infection with Neisseria gonorrhoeae (GC) and/or Chlamydia trachomatis (CT). (2) to estimate the number of infections that would be missed if anal diagnostic assays were not performed among patients who denied unprotected anorectal exposure in the preceding month. Methods and Findings: Retrospective analysis in HIV primary care and high resolution anoscopy (HRA) clinics. HIV-infected adult men were screened for self-reported exposure during the previous month at all primary care and HRA appointments. Four sub-cohorts were defined based on microbiology methodology (GC culture and CT direct fluorescent antibody vs. GC/ CT nucleic acid amplification test) and clinical setting (primary care vs. HRA). Screening question operating characteristics were estimated using contingency table methods and then pooled across subcohorts. Among 803 patients, the prevalence of anorectal GC/CT varied from 3.5-20.1% in the 4 sub-cohorts. The sensitivity of the screening question for self-reported exposure to predict anorectal STI was higher in the primary care than in the HRA clinic, 86-100% vs. 12-35%, respectively. The negative predictive value of the screening question to predict asymptomatic anorectal STI was $90% in all sub-cohorts. In sensitivity analyses, the probability of being an unidentified case among those denying exposure increased from 0.4- 8.1% in the primary care setting, and from 0.9-18.8% in the HRA setting as the prevalence varied from 1-20%. Conclusion: As STI prevalence increases, denial of unprotected anal-receptive exposure leads to an increasingly unacceptable proportion of unidentified asymptomatic anorectal STI if used as a criterion not to obtain microbiologic assays.

Spinal injuries are devastating, often leaving the patient paralyzed or with a permanent deficit. Aspiring athletes may not be able to persue their dreams secondary to a spinal injury; families are often left without a major wage earner to support them; and individuals are dependent upon others for the fulfillment of their basic needs. Education is essential for the prevention of primary and secondary spinal injuries; nurses play a key role in both these areas. [ABSTRACT FROM AUTHOR]

This article focuses on the trauma nurse practitioner's role with trauma patient population. Nurse practitioners are registered nurses who possess additional preparation, advanced education, and training enabling them to provide integrated quality healthcare. Trauma nurse practitioners possess a strong background in critical and emergency medicine. They are credentialed; hold full hospital privileges; have prescribing tights, including Drug Enforcement Administration (DEA) licenses; and provide a high level of medical expertise and patient satisfaction (AANP 2000). Within the complex trauma team, the nurse practitioner is the consistent thread, ensuring quality patient care through communication, teaching, and follow-up care. [ABSTRACT FROM AUTHOR]
