Understanding Attitudes of Postpartum Cisgender Women Toward Integration of HIV Prevention Services into Routine Prenatal and Postpartum Sexual Health Discussions.

Oral pre-exposure prophylaxis (PrEP) is an effective, user-controlled method for HIV prevention. However, awareness, uptake, and adherence to PrEP remain low among cisgender women (CGW). The prenatal and postpartum periods present an opportunity for delivery of comprehensive sexual health services that include HIV prevention education and services. However, little is known about postpartum CGW's attitudes toward integration of HIV prevention education and services into obstetric care in the US. We conducted semistructured interviews with 20 postpartum CGW in the Bronx, NY from July to November 2022 to explore their experiences with prenatal and postpartum sexual health care, examine their attitudes toward integration of HIV prevention services into obstetric sexual health care, and identify components of future implementation strategies. Transcripts were analyzed thematically using a framework approach. Among CGW interviewed, fewer than half reported prior knowledge of PrEP. Ten participants preferred long-acting injectable PrEP relative to six who preferred daily oral PrEP. Most participants reported no discussion of sex with their provider during pregnancy, and when discussions occurred, they focused on permission or prohibition of sexual activity. Participants described a reliance on providers to lead prenatal sexual health discussions. Even when not perceived as personally relevant, most respondents valued education on HIV prevention and PrEP services. In the postpartum period, sexual health discussions were similarly limited despite participants describing complex experiential sexual health concerns. This study supports the potential for integration of HIV prevention education and services into routine prenatal and postpartum sexual health discussions in an area of high HIV prevalence in the US.

Association of in utero HIV exposure with child brain structure and language development: a South African birth cohort study

BackgroundThere is a growing population of children with in utero HIV exposure who are at risk of poor neurodevelopmental outcomes despite avoiding HIV infection. However, the underlying neurobiological pathways are not understood and neuroimaging studies are lacking. We aimed to investigate the cortical brain structure of children who are HIV-exposed and uninfected (HEU) compared to HIV-unexposed (HU) children and to examine the relationship with neurodevelopment.MethodsThe Drakenstein Child Health birth cohort study enrolled pregnant women from a high HIV prevalence area in South Africa with longitudinal follow-up of mother–child pairs. High-resolution magnetic resonance imaging scans from 162 children (70 HEU; 92 HU) were acquired at 2–3 years of age. All HEU children were born to mothers taking antiretroviral therapy. Measures of brain structure (cortical thickness and surface area) in the prefrontal cortex regions were extracted from T1-weighted images and compared between groups using multivariate analysis of variance and linear regression. Child development, assessed using the Bayley Scales of Infant and Toddler Development-III, was correlated with cortical structure, and mediation analyses were performed.ResultsAnalyses demonstrated an association between HIV exposure and cortical thickness across the prefrontal cortex (p = 0.035). Children who were HEU had thicker cortices in prefrontal regions, with significantly greater cortical thickness in the medial orbitofrontal cortex (mOFC) bilaterally compared to HU children (3.21 mm versus 3.14 mm, p = 0.009, adjusted effect size 0.44 [95% CI 0.12 to 0.75]). Estimates held across multiple sensitivity analyses. There were no group differences in cortical surface area. Language scores, which were lower in HEU versus HU children (81.82 versus 86.25, p = 0.011, effect size − 0.44 [95% CI − 0.78 to − 0.09]), negatively correlated with prefrontal cortical thickness in both groups. Cortical thickness in the mOFC mediated the relationship between HIV exposure and poor language outcomes (Sobel test p = 0.032).ConclusionsIn this cohort study, exposure to HIV during pregnancy was associated with altered cortical structure in early life. Our findings indicate that differences in cortical thickness development in the prefrontal region in children who are HEU may be a pathway leading to language impairment. Longitudinal studies are needed to determine the lasting impact.

The salience of structural barriers and behavioral health problems to ART adherence in people receiving HIV primary care in South Africa

ABSTRACT Multilevel factors (individual and structural) influence adherence to antiretroviral therapy, particularly in high HIV prevalence areas such as South Africa. The present study examined the relative importance of structural barriers to HIV care and behavioral health factors, depression and alcohol use, in Khayelitsha, Cape Town, South Africa. People receiving HIV care in six primary care clinics in Khayelitsha (N = 194) completed the Center for Epidemiologic Studies Depression Scale, the Alcohol Use Disorders Identification Test, the Structural Barriers to Medication Taking questionnaire, and a qualitative rating of past-two-week adherence. Correlations were employed to examine associations among these variables, and hierarchical regression analysis was used to examine the unique effects of structural barriers over and above depression and alcohol use as predictors of adherence. Participants were primarily Black South African (99%) women (83%), and 41 years old on average. All four variables were significantly correlated. The hierarchical regression analysis showed that among behavioral health predictors, alcohol use alone significantly predicted ART adherence (b = -.032, p = .002). When structural barriers was added to the model, it was the only significant unique predictor of ART adherence (b = −1.58, p < .001). Findings highlight the need to consider structural vulnerabilities in HIV care in South Africa when developing behavioral health interventions.

Severe lower respiratory tract infections are associated with human adenovirus in hospitalised children in a high HIV prevalence area.

Viral causes of lower respiratory tract infections (LRTIs) are associated with increased mortality in children aged <5 years (U5). Human adenovirus (HAdV) has been associated with severe LRTI; however, its relationship with HIV and malnutrition in South Africa (SA) is not understood. To identify the prevalence of and factors associated with HAdV LRTIs in hospitalised U5 childen. Clinical and viral data on U5 children hospitalised with severe LRTI from January 2018 to June 2020 at King Edward VIII Hospital, Durban, SA, including results of a multiplex polymerase chain reaction (PCR) panel assay for respiratory viruses, were retrieved from inpatient files and laboratory databases and retrospectively analysed. Standard descriptive statistics and Pearson's χ², Fisher's exact and Mann-Whitney tests were used to determine significant associations with HAdV LRTI. Among the 206 viral assays analysed (15.6% of all LRTI admissions), HAdV was the most common virus identified. The cohort had a median (interquartile range) age of 5 (2 - 13) months, 47.3% had perinatal HIV exposure, and 34.5% had severe acute malnutrition (SAM). No seasonal pattern with HAdV could be demonstrated. SAM and prematurity were significant risk factors for readmission, and perinatal HIV exposure was a significant risk factor for presence of multiple viruses on analysis of a respiratory specimen. Detection of HAdV was not associated with an increased risk of requiring oxygen or ventilatory support. HAdV was the most common virus found on analysis of multiplex PCR panel results in children hospitalised with severe LRTI in SA, where high rates of HIV exposure may result in increased susceptibility to viral co-infections. The role of HAdV as a cause of severe LRTI in SA infants, who have high rates of HIV exposure, requires greater scrutiny. What the study adds. This study provides retrospective data identifying human adenovirus (HAdV) as the most common cause of severe lower respiratory tract infection (LRTI) in children aged <5 years (U5). The impact of respiratory syncytial virus as a common pathogen in children is well established. The study confirms anecdotal evidence that HAdV is an important disease-causing pathogen associated with LRTI. Children with perinatal HIV exposure and severe acute malnutrition (SAM) may be particularly susceptible.Implications of the findings. HAdV must be considered a major cause of severe LRTI in U5 children. Children with LRTI who had perinatal HIV exposure and those with SAM need to be tested for HAdV and to be monitored for severe disease.

Painful to Discuss: The Intersection of Chronic Pain, Mental Health, and Analgesic Use among People with HIV

Objective: This retrospective chart review study aims to identify patients in an HIV clinical setting in an area of high HIV prevalence in Atlanta, Georgia, USA who have chronic pain, analgesic prescriptions, and/or mental health diagnoses. Design: People living with HIV (PLWH) are at higher risk for experiencing trauma, mental health conditions, and chronic pain than their HIV-negative counterparts. This study was designed to evaluate the intersection of these factors within an urban HIV clinic. Methods: Retrospective chart review study. Results: Of the adult patients enrolled at an HIV clinic in Atlanta, Georgia USA between 2011-2022 (n=15,970), 93.7% were prescribed analgesics, 40.5% had documented pain diagnoses, and 23.5% had documented mental health diagnoses. Additionally, 14.3% of all enrolled patients had all three factors concurrently. Conclusions: The complexity of HIV, chronic pain, mental health challenges, and analgesic use demand a patient-centered, collaborative approach including a multidisciplinary care team. Seeing persistent pain among PLWH with a trauma-informed approach to care within the lens of co-occurring mental health diagnoses will allow us to better understand, treat, and sustain patients in life-saving HIV care.

An effectiveness-implementation trial protocol to evaluate PrEP initiation among U.S. cisgender women using eHealth tools vs. standard care.

The United States' (U.S.) initiative to End the HIV Epidemic aims to reduce new HIV infections in areas of high HIV prevalence. Despite national efforts to reduce HIV incidence, cisgender women continue to represent approximately one out of every five new HIV diagnoses in the U.S. Taking pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy; however, PrEP initiation among cisgender women is suboptimal, with only 10% of eligible women receiving PrEP prescriptions in 2019. We designed a trial to test the effectiveness of interventions to increase PrEP initiation, while evaluating the implementation strategy (hybrid type II trial) in seven obstetrics and gynecology (OB/GYN) clinics (two federally qualified health centers, three community-based, and two academic) in Baltimore, Maryland. A total of 42 OB/GYN providers will be enrolled and randomized (1:1:1) into one of three clinical trial arms (standard of care, patient-level intervention, or multi-level intervention). Eligible patients of enrolled providers will receive a sexual health questionnaire before their appointment through the electronic health record's (EHR) patient portal. The questionnaire will be scored in three tiers (low, moderate, and high) to assess HIV risk. Patients at low risk will be offered an HIV test only, while those who score medium or high risk will be included in the clinical trial and assigned to the clinical trial arm associated with their provider. Differences in PrEP initiation, our primary outcome, across the three arms will be analyzed using generalized linear mixed-effect models with logistic regression. We will adjust results for demographic differences observed between arms and examine PrEP initiation stratified by patient's and provider's race and ethnicity.Additionally, a comprehensive economic analysis for each intervention will be conducted. We hypothesize that gathering information on sensitive sexual behaviors electronically, communicating HIV risk in an understandable and relatable format to patients and OB/GYN providers, and deploying EHR alerts will increase PrEP initiation and HIV testing. The trial is registered with ClinicalTrials.gov (NCT05412433) on 09 June 2022. https://clinicaltrials.gov/ct2/show/NCT05412433?term=NCT05412433&draw=2&rank=1.

Children who are HIV-exposed and uninfected: evidence for action

Prior to widespread availability of antiretroviral therapy (ART) in sub-Saharan Africa, children who were HIV-exposed but uninfected (HEU) had increased mortality, morbidity and undernutrition compared with children who were HIV-unexposed. Scale-up of ART has led to impressive declines in vertical HIV transmission, but over 15 million children are now HEU, 90% of whom live in sub-Saharan Africa. There are ongoing health disparities among children who are HEU, with higher mortality, morbidity and stunting and modest impairments in early child development, which collectively hamper health and human capital in high prevalence countries. The underlying causes are multifactorial and include exposure to HIV, co-infections and a skewed antenatal inflammatory milieu, particularly if mothers start ART once they have advanced disease, as well as socioeconomic risk factors, which may cluster in HIV-affected households. Improving maternal health through early and sustained ART, ensuring optimal breastfeeding, and implementing evidence-based priority interventions for all children in areas of high HIV prevalence, will likely improve outcomes. A more comprehensive intervention package based on the Nurturing Care Framework may have particular benefits for children who are HEU, to close health gaps and ensure that the next generation of HIV-free children survive and thrive, and lead healthy and productive lives.

2070. Risk Factors Affecting PrEP Offering and Uptake Among At-Risk Youth in an Area of High HIV Prevalence

Abstract Background New HIV cases are steadily reported in our community among at-risk youth despite the availability of highly effective pre-exposure prophylaxis (PrEP). Although providers regularly offer PrEP during sexually transmitted disease (STD) screening visits, PrEP utilization rates remain low among those patients. The primary outcomes of this study are determining the rates of PrEP offering and uptake in high-risk individuals seeking care for STD screening at local youth clinics and whether these rates differ by demographic factors. Methods A retrospective chart review was conducted on 218 charts of patients ages 18 - 24 years with risk factors for HIV infection who sought care at a youth clinic in Tampa, FL between 2018 and 2020. PrEP offering and utilization rates were compared across demographic and risk factor variables using Chi-square tests for categorical variables and Mann-Whitney U tests for continuous variables. Results Of 218 patients, 86 (39.4%) were offered or had a documented discussion of PrEP at their visit but uptake occurred only in 22 (10.1%). Factors associated with offerings are depicted in table 1. Factors associated with uptake are depicted in table 2. Age at first visit, insurance type, level of education, and employment did not significantly impact PrEP offering or uptake. Additionally, there was no significant difference in PrEP uptake associated with race or ethnicity. PrEP Offerings Demographic characteristics associated with offering and uptake of PrEP among young people screened for STD in a high prevalence of HIV area PrEP Uptake Demographic characteristics associated with uptake of PrEP among young people screened for STD in a high prevalence of HIV area Conclusion This study highlights differences in offering and uptake of PrEP among young adults with a high risk of acquiring HIV living in a high prevalence of HIV area. Males and MSM are offered more PrEP and also use it more. Black patients are less likely to be offered PrEP. These differences emphasize the need for interventions to improve the rate of PrEP discussions among female and black patients at risk for HIV and to improve adherence to PrEP among young individuals at risk of HIV infection. Interventions targeting these demographics may lessen disparities and incidence of HIV in the community. Moving forward we will continue to investigate additional data collected on PrEP compliance at 6mo and at 12mo follow-ups among our patient population. Future studies with qualitative data identifying barriers to use PrEP will provide important information on this topic. Disclosures All Authors: No reported disclosures.

Abstract 10263: “High Blood Pressure Comes From Thinking Too Much”: Health Beliefs Among Couples With Cardiometabolic Disorders and HIV in Sub-Saharan Africa

Introduction: People living with HIV are at increased risk for cardiometabolic disorders (CMD) due to chronic inflammation, immune activation, and antiretroviral therapy. In high HIV prevalence areas of sub-Saharan Africa, little is known about how HIV patients and their partners understand CMD and how health services could leverage partner support. Objective: To explore health beliefs among HIV patients with CMD and primary partners Methods: We conducted a qualitative study with 25 couples recruited from 3 HIV care clinics in Zomba, Malawi. Patients managing HIV and CMD (hypertension and/or diabetes) were enrolled first, followed by their primary partners. Semi-structured interviews were conducted separately with partners to elicit health beliefs around causality, prevention, and management of CMD. Dyadic data were coded for patterns and themes within couples and between couples, and data matrices were created to compare and contrast the findings. Results: Most participants believed that the main causes of CMD were diet, aging, and genetics, but some believed CMD was sexually transmitted or caused by viruses such as HIV. Within couples, diet and stress were the most commonly agreed-upon cause, and over half of couples believed “thinking too much” due to stress or couple conflict was a cause of CMD. Prevention beliefs included a healthy diet, exercise, avoiding HIV, using condoms, and keeping stress levels low. Management beliefs included dietary changes, taking medication or herbs, exercising, and reducing stress. Within couples, the most agreed-upon belief was that diet, particularly salt reduction, was important for prevention and management; however, within-dyad disagreement and incorrect beliefs around other aspects of a heart-healthy diet were common. Conclusion: While lifestyle factors were correctly identified as important for prevention and management of CMD, misconceptions remained around transmission through a virus or sex. Partners often differed in their views of CMD, which could interfere with CMD management. Health education programs are critically needed and involving partners may offer an opportunity to solidify knowledge in couples and foster collaborative disease management around CMD.

Accelerating ontological security for South African adolescents living in high HIV-prevalence areas: a longitudinal study

ABSTRACT Ontological security is the personal need to build fundamental certainty about the continuity of life events. It is central to long-term human development, particularly among adolescents in highly vulnerable communities in South Africa. We examined the cumulative effects of eight hypothesised provisions (development accelerators) in reducing the risks of ontological insecurity outcomes aligned with Sustainable Development Goals (SDGs) targets. Three waves of survey data from adolescents living in high HIV prevalence areas in South Africa were analysed. We used standardised tools to measure twelve outcomes linked to two dimensions of ontological security: mental health and violence. Sustained receipt (at baseline and follow-ups) of eight hypothesised accelerators were examined: emotional and social support, parental/caregiver monitoring, food sufficiency, accessible health care, government cash transfers to households, basic economic security, positive parenting/caregiving, and participation in extramural activities. Associations of all accelerators with outcomes were evaluated using multivariable regressions controlling for age, sex, orphanhood and HIV status, rural/urban location, and informal housing. Cumulative effects were tested using marginal effects modelling. Of 1,519 adolescents interviewed at baseline, 1,353 (89%) completed the interviews at two follow-ups. Mean age was 13.8 at baseline; 56.6% were female. Four provisions were associated with reductions in twelve outcomes. Combinations of accelerators resulted in a percentage reduction risk in individual indicators up to 18.3%. Emotional and social support, parental/caregiver monitoring, food sufficiency and accessible health care by themselves and in combination showed cumulative reductions across twelve outcomes. These results deepen an essential understanding of the long-term effects of consistent exposure to accelerators on multi-dimensional human development. They could be directly implemented by existing evidence-based interventions such as peer-based psychosocial support, parenting programmes, adolescent-responsive healthcare and food support, providing safer and healthier environments for South African adolescents to thrive.

Attrition from Care Among Men Initiating ART in Male-Only Clinics Compared with Men in General Primary Healthcare Clinics in Khayelitsha, South Africa: A Matched Propensity Score Analysis

Men have higher rates of attrition from antiretroviral therapy (ART) programs than women. In Khayelitsha, a high HIV prevalence area in South Africa, two public sector primary healthcare clinics offer services, including HIV testing and treatment, exclusively to men. We compared attrition from ART care among men initiating ART at these clinics with male attrition in six general primary healthcare clinics in Khayelitsha. We described baseline characteristics of patients initiating ART at the male and general clinics from 1 January 2014 to 31 March 2018. We used exposure propensity scores (generated based on baseline health and age) to match male clinic patients 1:1 to males at other clinics. The association between attrition (death or loss to follow-up, defined as no visits for nine months) and clinic type was estimated using Cox proportional hazards regression. Follow-up time began at ART initiation and ended at attrition, clinic transfer, or dataset closure. Before matching, patients from male clinics (n = 784) were younger than males from general clinics (n = 2726), median age: 31.2 vs 35.5 years. Those initiating at male clinics had higher median CD4 counts at ART initiation [Male Clinic 1: 329 (IQR 210–431), Male Clinic 2: 364 (IQR 260–536), general clinics 258 (IQR 145–398), cells/mm3]. In the matched analysis (1451 person-years, 1568 patients) patients initiating ART at male clinics had lower attrition (HR 0.71; 95% CI 0.60–0.85). In separate analyses for each of the two male clinics, only the more established male clinic showed a protective effect. Male-only clinics reached younger, healthier men, and had lower ART attrition than general services. These findings support clinic-specific adaptations to create more male-friendly environments.

Perceptions of cervical cancer and motivation for screening among women in Rural Lilongwe, Malawi: A qualitative study.

IntroductionCervical cancer is the leading cause of cancer death among women in Malawi. Low awareness of cervical cancer and negative perceptions of screening can prevent women from participating in preventative strategies. We sought to explore perceptions and motivations for screening among women who participated in a cervical cancer screen-and-treat pilot study in rural Malawi.Materials and methodsWe conducted a qualitative sub-study of a community-based cervical cancer screen-and-treat pilot study in rural Lilongwe between July-August 2017. From October 2017-February 2018, 17 women who underwent screening using visual inspection with acetic acid (VIA) and same-day thermal ablation treatment were recruited at their 12-week follow-up visit post treatment to participate in this qualitative sub-study. Semi-structured interview guides that explored baseline knowledge of cervical cancer, perceptions, and motivation for screening were used for in-depth interviews (IDIs). IDIs were conducted in the local language, Chichewa, translated and transcribed to English. Data was analyzed using NVivo® V12.0.ResultsFindings included fatalistic views on cancer, but limited knowledge specific to cervical cancer. Misconceptions of cervical cancer screening were common; however, there was a unique understanding of screening as prevention (i.e., finding and treating early disease to prevent progression to worsening disease). This understanding appeared to stem from HIV prevention concepts known to the community. Motivations for screening included desire to know one’s health status, convenience of community-based screening, and peer encouragement.ConclusionDespite limited knowledge of cervical cancer and misconceptions of screening, the concept of screening for prevention, desire to know one’s health status, convenient access, and peers’ influence were motivators for participation in screening. Cervical cancer screen-and-treat programs in high HIV prevalence areas should consider utilizing language that parallels HIV prevention language to communicate the need for cervical cancer screening and treatment and utilize prevention concepts that may already be familiar to women living there.

Institutional Responses to Drought in a High HIV Prevalence Setting in Rural South Africa.

In 2015, South Africa experienced one of the worst (El Niño-induced) droughts in 35 years. This affected economic activities, individual and community livelihoods and wellbeing especially in rural communities in northern KwaZulu-Natal. Drought’s direct and indirect impacts on public health require urgent institutional responses, especially in South Africa’s stride to eliminate HIV as a public health threat by 2030 in line with the UNAIDS goals. This paper draws on qualitative data from interviews and policy documents to discuss how the devastating effect of the 2015 drought experience in the rural Hlabisa sub-district of uMkhanyakude, a high HIV prevalence area, imposes an imperative for more proactive institutional responses to drought and other climate-related events capable of derailing progress made in South Africa’s HIV/AIDS response. We found that drought had a negative impact on individual and community livelihoods and made it more difficult for people living with HIV to consistently engage with care due to economic losses from deaths of livestock, crop failure, food insecurity, time spent in search of appropriate water sources and forced relocations. It also affected government institutions and their interventions. Interviewed participants’ reflections on drought-related challenges, especially those related to institutional and coordination challenges, showed that although current policy frameworks are robust, their implementation has been stalled due to complex reporting systems, and inadequate interdepartmental collaboration and information sharing. We thus argue that to address the gaps in the institutional responses, there is a need for more inclusive systems of drought-relief implementation, in which government departments, especially at the provincial and district levels, work with national institutions to better share data/information about drought-risks in order to improve preparedness and implementation of effective mitigation measures.

Demographics and incidence of anal squamous cell carcinoma in people living in high HIV prevalence geographical areas

Prevention of Perinatal HIV Transmission in an Area of High HIV Prevalence in the United States

In 2014, the US Department of Health and Human Services modified the perinatal HIV management guidelines suggesting that women are considered low risk if they are living with HIV on antiretroviral therapy (ART) with HIV RNA ≤1000 copies per mL in late pregnancy and near delivery. In this population, it no longer recommended to administer maternal intrapartum intravenous zidovudine. In addition, for low-risk HIV-exposed infants (HEI), prophylaxis recommendation is 4 weeks of zidovudine after birth, whereas for high-risk HEI, it is 6 weeks of either a dual or triple therapy with zidovudine. This study was designed to help understand the use of these new perinatal HIV prevention interventions by evaluating the risk of perinatal HIV transmission in mother–infant pairs in a high HIV prevalence US area.In this study, researchers included 551 HIV-exposed infants (HEI) and 542 mothers living with HIV in the Washington, District of Columbia, area who were evaluated at Special Immunology Services in Children’s National Hospital between January 2013 and December 2017.A retrospective cohort analysis of these mother–infant pairs was completed, assessing a number of characteristics but, most notably, antiretroviral treatment during the pregnancy, HIV viral load at delivery, intrapartum zidovudine, delivery type (cesarean delivery versus vaginal), antiretroviral prophylaxis regimen for infant, antiretroviral prophylaxis duration for infant, and final HIV status of infant.The majority of mothers received antiretrovirals (95.5%), had HIV RNA ≤1000 copies per mL before delivery (81.9%), and received intrapartum zidovudine (65.5%). The majority of all HEIs were low risk (82.6); among these low-risk HEIs, slightly over one-half were delivered via cesarean delivery, and 62.9% received intrapartum zidovudine. In the study population, 9 infants acquired HIV perinatally and were all in the high-risk category, and not all of these infants were on dual or triple therapy with zidovudine.In this study, the researchers highlighted that the newer perinatal HIV recommendations have not been completely adopted because they showed 62.9% of the low-risk patients received intrapartum zidovudine, despite it no longer being recommended. Furthermore, of the 9 infants who acquired HIV perinatally, they were all considered high risk, but 6 were not on a dual or triple therapy. Certain factors can affect the decision to initiate combination antiretroviral therapy; however, in this study, it is suggested there were possible missed opportunities for use of this treatment as a prevention of perinatal HIV transmission.As the field of HIV and perinatal treatment of mother–infant pairs evolves and new recommendations emerge, it is essential the medical community strives to follow these recommendations as closely as possible to decrease perinatal HIV transmission. Adhering to the recommendations would minimize the medication exposures to those low-risk patients, while optimizing the antiretroviral regimen for high-risk HEIs, leading to the lowest perinatal HIV-transmission possible.

Accelerating Sustainable Development Goals for South African adolescents from high HIV prevalence areas: a longitudinal path analysis

BackgroundAdolescents experience a multitude of vulnerabilities which need to be addressed in order to achieve the Sustainable Development Goals (SDGs). In sub-Saharan Africa, adolescents experience high burden of HIV, violence exposure, poverty, and poor mental and physical health. This study aimed to identify interventions and circumstances associated with three or more targets (“accelerators”) within multiple SDGs relating to HIV-affected adolescents and examine cumulative effects on outcomes.MethodsProspective longitudinal data from 3401 adolescents from randomly selected census enumeration areas in two provinces with > 30% HIV prevalence carried out in 2010/11 and 2011/12 were used to examine six hypothesized accelerators (positive parenting, parental monitoring, free schooling, teacher support, food sufficiency and HIV-negative/asymptomatic caregiver) targeting twelve outcomes across four SDGs, using a multivariate (multiple outcome) path model with correlated outcomes controlling for outcome at baseline and socio-demographics. The study corrected for multiple-hypothesis testing and tested measurement invariance across sex. Percentage predicted probabilities of occurrence of the outcome in the presence of the significant accelerators were also calculated.ResultsSample mean age was 13.7 years at baseline, 56.6% were female. Positive parenting, parental monitoring, food sufficiency and AIDS-free caregiver were variously associated with reductions on ten outcomes. The model was gender invariant. AIDS-free caregiver was associated with the largest reductions. Combinations of accelerators resulted in a percentage reduction of risk of up to 40%.ConclusionPositive parenting, parental monitoring, food sufficiency and AIDS-free caregivers by themselves and in combination improve adolescent outcomes across ten SDG targets. These could translate to the corresponding real-world interventions parenting programmes, cash transfers and universal access to antiretroviral treatment, which when provided together, may help governments in sub-Saharan Africa more economically to reach their SDG targets.

A Systematic Review of Neighborhood-Level Influences on HIV Vulnerability.

A better understanding of the social-structural factors that influence HIV vulnerability is crucial to achieve the goal of ending the HIV epidemic by 2030. Given the role of neighborhoods in HIV outcomes, synthesis of findings from such research is key to inform efforts toward HIV eradication. We conducted a systematic review to examine the relationship between neighborhood-level factors (e.g., poverty) and HIV vulnerability (via sexual behaviors and substance use). We searched six electronic databases for studies published from January 1, 2007 through November 30, 2017 (PROSPERO CRD42018084384). We also mapped the studies’ geographic distribution to determine whether they aligned with high HIV prevalence areas and/or the “Ending the HIV Epidemic: A Plan for the United States”. Fifty-five articles met inclusion criteria. Neighborhood disadvantage, whether measured objectively or subjectively, is one of the most robust correlates of HIV vulnerability. Tests of associations more consistently documented a relationship between neighborhood-level factors and drug use than sexual risk behaviors. There was limited geographic distribution of the studies, with a paucity of research in several counties and states where HIV incidence/prevalence is a concern. Neighborhood influences on HIV vulnerability are the consequence of centuries-old laws, policies and practices that maintain racialized inequities (e.g., racial residential segregation, inequitable urban housing policies). We will not eradicate HIV without multi-level, neighborhood-based approaches to undo these injustices. Our findings inform future research, interventions and policies.

HIV knowledge and attitudes among minority pregnant patients and their non-pregnant partners in an urban hospital clinic

ObjectiveHIV seroconversion during pregnancy disproportionately affects urban, minority pregnant individuals. In order to prevent perinatal HIV transmission, it is essential that individuals are aware of HIV risk factors and effective transmission prevention strategies are employed. Thus, we aimed to examine knowledge about HIV transmission and attitudes about HIV among low-income, minority pregnant individuals and their partners living in a high HIV prevalence area. MethodsIn this qualitative study, pregnant participants were HIV-seronegative individuals receiving publicly-funded prenatal care in an urban academic center in the United States. Pregnant individuals and their partners were recruited to participate in a quality improvement program offering HIV testing to partners of pregnant people. Semi-structured guides were used to conduct individual interviews about participant sources of information about HIV, knowledge about transmission, and attitudes regarding those living with HIV. Transcripts were analyzed using the constant comparative method to determine themes and subthemes. ResultsOf 51 participants, 29 were pregnant individuals and 22 were non-pregnant partners. We found that inaccurate knowledge about perinatal HIV transmission was prevalent. Sources of information about HIV included reputable literary information or educational experiences, broadcast media, and word-of-mouth sources. Participants held dichotomous perceptions of people living with HIV. ConclusionsAmong low-income, minority pregnant people and their partners in a high HIV prevalence area, inaccuracies and lack of knowledge about HIV transmission were common. Efforts to educate pregnant individuals and their partners about HIV and perinatal HIV transmission should address common misconceptions and use popular sources of information.

Delivering PrEP to Young Women in a Low-Income Setting in South Africa: Lessons for Providing Both Convenience and Support

Daily oral pre-exposure prophylaxis (PrEP) is a key tool in addressing high HIV incidence among young women, and breaking the cycle of transmission. From 2017 to 2020, Médecins Sans Frontières (MSF) offered PrEP, in conjunction with contraception and risk-reduction counselling, to women aged 18–25, in a government-run clinic in Khayelitsha, a low income high HIV prevalence area in South Africa. Drawing on clinical, quantitative, and qualitative interview data, we describe participants’ experiences and engagement with the PrEP program, participant adherence (measured by TFV-DP levels in dried blood spots) over time, and the indirect benefits of the PrEP program. Of 224 screened and eligible participants, 164 (73.2%) initiated PrEP, with no large differences between those who initiated and those who did not. Overall, 47 (29%) completed 18 months follow-up, with 15 (9.1%) attending all visits. 76 (46.9%) participants were lost to follow-up, 15 (9.1%) exited when leaving the area, and 28.7% of exits happened in the first month of the study. We identified two different trajectories of PrEP adherence: 67% of participants had, on average, consistently low TFV-DP levels, with the remaining 33% having sustained high adherence. Few baseline characteristics predicted good adherence. The main reported barrier to taking PrEP was forgetting to take or travel with the pills. Encouragement from others declined as a reported facilitator from month 6 to 18 (family: 93.1% vs 77.6%, p = 0.016, friends: 77.6% vs 41.4%, p ≤ 0.001, partners: 62.1% vs 46.6%, p = 0.096, other PrEP users: 89.7% vs 74.1%, p = 0.020). Disclosure to friends and family in some cases opened dialogue around sex, and helped to educate others about PrEP. Self-reported sex with more than one partner, and sex without a condom, decreased significantly after enrolment (p < 0.001, p = 0.063). In the individual interviews, participants credited their PrEP experience with changing their behaviour. Recognising the challenges with, but overall benefits from a package of care that includes the option of PrEP, lessons drawn from this study can help maximise persistence on PrEP within resource constraints. PrEP providers need to address participants’ need for both convenience and social support.

Circumcision as an Intervening Strategy against HIV Acquisition in the Male Genital Tract

Unsafe sex with HIV-infected individuals remains a major route for HIV transmission, and protective strategies, such as the distribution of free condoms and pre-or post-prophylaxis medication, have failed to control the spread of HIV, particularly in resource-limited settings and high HIV prevalence areas. An additional key strategy for HIV prevention is voluntary male circumcision (MC). International health organizations (e.g., the World Health Organization, UNAIDS) have recommended this strategy on a larger scale, however, there is a general lack of public understanding about how MC effectively protects against HIV infection. This review aims to discuss the acquisition of HIV through the male genital tract and explain how and why circumcised men are more protected from HIV infection during sexual activity than uncircumcised men who are at higher risk of HIV acquisition.
