A Single Question on Maternal HIV Status Can Improve Identification of Children Living With HIV in South Africa.

Screening tools to improve identification of children living with HIV (CLHIV) have been validated and used in various settings. The aim of our study was to optimize a screening tool for Primary Healthcare Clinics (PHCs) in South Africa (SA). A cross-sectional study was conducted at PHCs in Johannesburg and Mopani Districts, between June 2021 and June 2022. Children 5-14 years of age with HIV negative or unknown status accompanied by their mothers, or appropriate caregivers, were enrolled. Demographic data, responses to the screening tool questions, and HIV test results were captured. Logistic regression modeling was used to optimize an existing 10-item screening tool, and sensitivity, specificity, and number needed to test (NNT) used to choose the final tool. We enrolled 14,147 children in the study, with 62 children testing HIV positive (HIV positivity of 0.4%). The 10-item tool with a single positive response had a sensitivity of 91.9% and specificity of 43.3%. An optimal combination of 5-items with two positive responses had the lowest NNT of 72, 82.3% sensitivity and 74.2% specificity. Maternal HIV status alone, HIV positive or unknown, had a 95.2% sensitivity, 65.0% specificity and NNT of 84. The 1-item tool only would have missed 5% of CLHIV (N = 3) compared with the 5-item tool that missed 18% (n = 11). A 1-item screening tool asking about maternal HIV status can improve efficiency of testing of children in primary healthcare facilities in SA and improve identification of CLHIV who are not on treatment.

Assessing behavioral economic biases among young adults who have increased likelihood of acquiring HIV: a mixed methods study in Baltimore, Maryland

BackgroundBehavioral economic (BE) biases have been studied in the context of numerous health conditions, yet are understudied in the field of HIV prevention. This aim of this study was to quantify the prevalence of four common BE biases—present bias, information salience, overoptimism, and loss aversion—relating to condom use and HIV testing in economically-vulnerable young adults who had increased likelihood of acquiring HIV. We also qualitatively examined participants’ perceptions of these biases.Methods43 participants were enrolled in the study. Data were collected via interviews using a quantitative survey instrument embedded with qualitative questions to characterize responses. Interviews were transcribed and analyzed using descriptive statistics and deductive-inductive content analyses.Results56% of participants were present-biased, disproportionately discounting future rewards for smaller immediate rewards. 51% stated they were more likely to spend than save given financial need. Present-bias relating to condom use was lower with 28% reporting they would engage in condomless sex rather than wait one day to access condoms. Most participants (72%) were willing to wait for condom-supported sex given the risk. Only 35% knew someone living with HIV, but 67% knew someone who had taken an HIV test, and 74% said they often think about preventing HIV (e.g., high salience). Yet, 47% reported optimistically planning for condom use, HIV discussions with partners, or testing but failing to stick to their decision. Most (98%) were also averse (b = 9.4, SD ±.9) to losing their HIV-negative status. Qualitative reasons for sub-optimal condom or testing choices were having already waited to find a sex partner, feeling awkward, having fear, or not remembering one’s plan in the moment. Optimal decisions were attributed qualitatively to self-protective thoughts, establishing routine care, standing on one’s own, and thinking of someone adversely impacted by HIV. 44% of participants preferred delayed monetary awards (e.g., future-biased), attributed qualitatively to fears of spending immediate money unwisely or needing time to plan.ConclusionMixed methods BE assessments may be a valuable tool in understanding factors contributing to optimal and sub-optimal HIV prevention decisions. Future HIV prevention interventions may benefit from integrating savings products, loss framing, commitment contracts, cues, or incentives.

An Assessment of HIV Risk, Perceptions of Risk, and Potential Adherence to Preexposure Prophylaxis Among HIV-Negative People With Injection Drug Use Who Access Mobile Outreach Services.

The purpose of this study was to assess HIV risk, perceptions of risk, and potential adherence to preexposure prophylaxis (PrEP) for the prevention of HIV infection among people who inject drugs (PWID), who self-report HIV negative status and access mobile outreach intravenous drug use (IVDU) services. Participants (N = 93) were non-Hispanic White (59.1%) and Hispanic (36.6%), between the ages of 18 and 63 years, primarily male (58.1%), who reported a length of IVDU between 1 and >20 years and accessed mobile outreach IVDU services in a metropolitan area of the Southwestern United States; all self-reported HIV-negative status. Self-report questionnaires completed via iPad included HIV risk behavior, perceived risk of HIV, and beliefs about medicines. PWID perceived themselves at a low risk for HIV with minimal concerns about contracting HIV. High levels of comorbidities (schizophrenia, anxiety, depression, hepatitis, diabetes, and hypertension), substance use, and limited HIV protective behavior and social support existed; women reported significantly more risk behaviors and comorbidities. Positive attitudes toward and interest in use of medication for HIV prevention were present, however, with concurrent concerns regarding long-term medication use and the potential to forget medications. PrEP adherence for PWID presents challenges for clinicians. Addressing perceptions of PrEP, perceived and actual risk for contracting HIV, potential barriers to PrEP adherence, social support, and treatment of comorbidities in primary care and IVDU outreach services potentially enhances PrEP maintenance among PWID, notably women.

Intersecting Sexual Behavior and Gender Identity Stigmas Among Transgender Women in the United States: Burden and Associations with Sexual Health.

In the United States, a context of multiple marginalization shapes sexual health disparities experienced by transgender women. Using data from 396 transgender women with negative or unknown HIV status, we performed exploratory factor analysis on responses to gender identity and sexual behavior stigma items and regressed sexual health outcomes on extracted factors via modified Poisson regression with robust variance estimation. Overall, 97.2% of participants endorsed ≥ 1 gender identity stigma; 67.2% endorsed ≥ 1 sexual behavior stigma; and 66.9% endorsed ≥ 1 of each. Extracted factors included gender-identity social stigma, reflecting experiences related to family, fearfulness in public, and verbal harassment (α = 0.68); gender-identity institutional stigma/violence, reflecting experiences related to healthcare, police interactions, and interpersonal violence (α = 0.73); and global sexual behavior stigma, reflecting experiences related to family, friends, and healthcare, as well as police interactions, fearfulness in public, verbal harassment,and interpersonal violence (α = 0.83). Gender-identity social stigma was significantly, positively associated with testing for HIV and testing for sexually transmitted infections. Gender-identity institutional stigma/violence and global sexual behavior stigma were both significantly, positively associated with condomless anal sex, sex work, testing for HIV, testing for sexually transmitted infections, and use of HIV pre-exposure prophylaxis. Stigma-mitigation remains critical to improve quality of life and sexual health for transgender women in the United States.

Decision-Making for HIV AIDS Prevention: Altruism and the Moral Norm

ABSTRACT The purpose of this enquiry was to understand how gay men form and maintain their attitudes toward HIV transmission preventative behaviors. Autobiographical life histories of sixteen gay men showed that once they acquired knowledge of preventative behavior they consistently adhered to that behavior. They adhered because of fear of HIV infection and because they held a moral norm that obligated them to behave altruistically (Schwartz, 1977) to protect not only themselves, but also their sex partners, loved ones, and their positive self-evaluation. They saw their HIV negative status, and their adherence, as pre-requisite and enabler for achieving their goals in life. Dick and Basu’s (1994) Framework for Customer Loyalty, a commercial marketing communications theoretical framework, explains development and maintenance of these men’s loyalty (their consistent adherence). This understanding, within a marketing communications framework, will inform development of social marketing communications aiming to increase adherence to behaviors that prevent HIV transmission.

Specific Parameters of Detection of Fungi of the Genus <i>Aspergillus</i> in Respiratory Organs of Pulmonary Tuberculosis Patients

The objective: to study specific parameters of detection of fungi of the genus Aspergillus in respiratory organs of pulmonary tuberculosis patients.Subjects and Methods. In 2019-2021, the samples of sputum or bronchoalveolar lavage of 520 patients above 18 years old with confirmed pulmonary tuberculosis and HIV-negative status were tested for molds. Also, all patients had their sputum or BAL tested for acid fast mycobacteria (AFB), cultures of M. tuberculosis (MBT), and DNA of tuberculous mycobacteria.Results. Positive culture results for fungi were obtained in 50/520 (9.62%; 95% CI 7.37-12.45, Wilson test) pulmonary tuberculosis patients. Species identification revealed fungi of the genus Aspergillus in 46/50 (92%) of them.In 37/46 (80.43%; 95% CI 66.83-89.35) patients, a single type (one species of Aspergillus) was identified, in 9/46 (19.57%; 95% CI 10.65-33.17) two types were identified. A. fumigatus (16/37 isolates, 43.24%) and A. niger (13/37 isolates, 35.14%) prevailed among single types of cultures. A. niger + A. flavus (3/9 isolates, 33.33%) was the most frequent combination. The ratio of the effectiveness of methods for detecting fungi such as culture/direct microscopy/galactomannan antigen in serum and BAL was 100/84.78/4.35% and 67.39%, respectively. Thus, BAL is more preferable than serum for detection of galactomannan antigen in patients with tuberculosis.Only in 8/46 (17.4%) patients, bacterial excretion was detected by culture, which is typical for the active phase of the course of tuberculosis. In the remaining 38 (82.6% 95% CI 69.28-90.91) patients, no tuberculous mycobacteria were detected by culture, which was typical of stabilization and cure of tuberculosis.

HIV and Seroconversion among Pregnant Women at the University Hospital of Mother and Child in Chad

Background: HIV in pregnant women presented a risk of transmission to newborns. This study was to determine HIV prevalence among pregnant women in the birthing rooms and give antiretrovirals to women infected and their newborns. Methods: A preliminary study was conducted from 2013 to 2015 at the Mother and Child Hospital. Pregnant women were counseled and tested for HIV-antibody according to the national algorithm using Determine HIV 1 & 2 and Immunocomb II Bispot HIV1 & 2. The women screened HIV-negative during the prenatal consultation and who accepted a second test were screened in the birth room. The data collected were processed using the Access Microsoft office 16 and SPSS software version 18. Results: A total of 6080 pregnant women were tested before and in the birth room. Of these, 5943 (97.4%) were detected as HIV-negative and 159 (2.6%) were HIV-positive. Of the 5943 with HIV-negative status, 1333 accepted the second test in the birth room, 10 of which have become HIV-positive. The rate of seroconversions was 0.75%. Conclusion: This study determined the prevalence of HIV in pregnant women. The result reveals the importance and necessity of repeating the screening test in the birth room because of the possibility of seroconversion or new infection during pregnancy.

Preferences for PrEP modalities among gay, bisexual, and other men who have sex with men from Brazil, Mexico, and Peru: a cross-sectional study.

Pre-exposure prophylaxis (PrEP) scale-up is urgent to reduce new HIV cases among gay, bisexual, and other men who have sex with men (MSM) in Latin America. Different PrEP modalities may increase PrEP uptake and adherence, especially among young MSM. To assess preferences for PrEP modalities among MSM from Brazil, Mexico, and Peru. Cross-sectional web-based study (March-May 2018) targeting MSM through advertisements on Grindr, Hornet, and Facebook. We included MSM aged ⩾ 18 years and who reported HIV-negative status. We assessed preferences for PrEP modalities with the following question: 'Considering that all following PrEP modalities were available, which one would you prefer considering a scale from 1 to 3 (1 = most preferred): daily oral PrEP, event-driven PrEP (ED-PrEP), and long-acting injectable PrEP'. We assessed factors associated with each most preferred PrEP modality per country using multivariable logistic regression models. A total of 19,457 MSM completed the questionnaire (Brazil: 58%; Mexico: 31%; Peru: 11%); median age was 28 years [interquartile range (IQR): 24-34]. Overall, injectable PrEP was the most preferred modality [42%; 95% confidence interval (CI): 41-43], followed by daily PrEP (35%; 95% CI: 34-35), and ED-PrEP (23%; 95% CI: 23-24). In multivariable models, preferring injectable PrEP was associated with PrEP awareness in all three countries, while PrEP eligibility only in Brazil. Preferring daily PrEP was associated with younger age and lower income in Brazil and Mexico, and lower education only in Brazil. The odds of preferring ED-PrEP were lower among MSM aware and eligible for PrEP in Brazil and Mexico. Long-acting injectable PrEP was the preferred PrEP modality among MSM in Brazil, Mexico, and Peru, especially those aware and eligible for PrEP. Public health interventions to increase PrEP modalities literacy and availability in Latin America are urgent especially among MSM of young age, lower income, and lower education.

Sexualized Substance Use among Female Sex Workers in Iran: Findings from a Nationwide Survey

Background: Female sex workers (FSWs) are at higher risk of HIV due to high-risk sexual and drug use related behaviors. This study characterized sexualized substance use among FSWs in Iran. Methods: In 2015, 1,337 FSWs were recruited from centers for vulnerable women and through outreach efforts in 13 major cities in Iran. Data were collected via face-to-face interviews from consenting FSWs on a range of socio-demographic and behavioral characteristics. The primary outcome of interest was sexualized substance use, defined as reporting alcohol or drug use before or during sex in the past month. Bivariable and multivariable modified Poisson regression models were used to assess the correlates of sexualized substance use. Adjusted prevalence ratio (aPR) and 95% confidence interval (CI) were reported. Results: The prevalence of sexualized substance use was 31.3% (95% CI: 28.7, 34.0). Inconsistent condom use during sex with clients in the past month (aPR = 1.31; 95% CI: 1.01, 1.71), regular (i.e., at least weekly in the past month) alcohol use (aPR = 2.87; 95% CI: 2.17, 3.80), regular opioid use (aPR = 2.09; 95% CI: 1.45, 3.02), regular stimulant use (aPR = 2.68; 95% CI: 2.12, 3.39), and self-reported HIV negative status (aPR= 1.88; 95% CI: 1.14, 3.10) were significantly and positively associated with sexualized substance use. Conclusions: Sexualized substance use was associated with riskier sexual behavior and self-reported HIV sero-negativity. Harm reduction messaging to FSWs needs to go beyond focusing on sexual health promotion and further highlight the risks associated with sexualized substance use.

HIV Self-testing and Risk Behaviors Among Men Who Have Sex With Men in 23 US Cities, 2017

HIV self-testing (HIVST) is a promising strategy to expand the HIV care continuum, particularly among priority populations at high risk of HIV infection. However, little is known about HIVST uptake among men who have sex with men (MSM) outside of clinical trial settings. To evaluate HIVST use among urban MSM in the US who reported testing within the past 12 months. A cross-sectional study of adult MSM in the 2017 National HIV Behavioral Surveillance system, which used venue-based sampling methods to collect data related to HIV testing, receipt of prevention services, and risk factors for HIV, was conducted at 588 venues in 23 urban areas in the contiguous US and Puerto Rico. All participants were offered HIV testing. Adult cisgender MSM who reported HIV-negative or unknown HIV status and obtained HIV testing in the past 12 months were included. Data for this study were collected between June 4, 2017, and December 22, 2017, and analyzed between October 23, 2020, and August 20, 2021. Self-reported HIVST in the past year. Adjusted prevalence ratios (aPRs) using survey weights were calculated to assess factors associated with HIVST. A total of 6563 MSM in 23 urban areas met inclusion criteria, of whom 506 (7.7%) individuals reported HIVST in the past year. The median age of self-testers was 29 (IQR, 25-35) years, 52.8% had completed college, and 37.9% reported non-Hispanic White race. One self-tester reported seroconverting in the prior 12 months, and an additional 10 self-testers were diagnosed with HIV during the survey. HIVST was associated with sexual orientation disclosure (aPR, 10.27; 95% CI, 3.45-30.60; P < .001), perceived discrimination against people with HIV (aPR, 1.53; 95% CI, 1.09-2.03; P = .01), younger age (aPR, 0.74; 95% CI, 0.66-0.84; P < .001), higher educational level (aPR, 1.20; 95% CI, 1.04-1.37; P = .01), and higher income levels (aPR, 1.18; 95% CI, 1.04-1.32; P = .009). No association was noted with condomless anal sex (aPR, 0.96; 95% CI, 0.88-1.06, P = .88), sexually transmitted infections (aPR, 0.96; 95% CI, 0.70-1.30; P = .77), or preexposure prophylaxis use (aPR, 0.99; 95% CI, 0.75-1.30; P = .92). In this study, HIVST was relatively uncommon in this sample of urban MSM. HIVST may not be reaching those with lower socioeconomic status or who have not disclosed their sexual identity. The findings of this study suggest that efforts to increase HIVST should focus on engaging underserved and vulnerable subgroups of MSM.

The Use of HIV Pre- and Postexposure Prophylaxis Among a Web-Based Sample of HIV-Negative and Unknown Status Cisgender and Transgender Sexual Minority Men: Cross-sectional Study.

HIV disproportionately affects sexual minority men (SMM) in the United States. We sought to determine past HIV postexposure prophylaxis (PEP) use and current and prior pre-exposure prophylaxis (PrEP) use among a web-based sample of cisgender and transgender men who have sex with men. In 2019, HIV-negative and unknown status SMM (n=63,015) were recruited via geosocial networking apps, social media, and other web-based venues to participate in a brief eligibility screening survey. Individuals were asked about past PEP use and current and prior PrEP use. We examined associations of demographics, socioeconomic indicators, and recent club drug use with PEP and PrEP use, as well as the association between past PEP use and current and prior PrEP use using generalized linear models and multinomial logistic regression. Statistical significance was considered at P<.001, given the large sample size; 99.9% CIs are reported. Prior PEP use was reported by 11.28% (7108/63,015) of the participants, with current or prior PrEP use reported by 21.95% (13,832/63,015) and 8.12% (5118/63,015), respectively. Nearly half (3268/7108, 46%) of the past PEP users were current PrEP users, and another 39.9% (2836/7108) of the participants who reported past PEP use also reported prior PrEP use. In multivariable analysis, past PEP use was associated with current (relative risk ratio [RRR] 23.53, 99.9% CI 14.03-39.46) and prior PrEP use (RRR 52.14, 99.9% CI 29.39-92.50). Compared with White men, Black men had higher prevalence of past PEP use and current PrEP use, Latino men had higher prevalence of PEP use but no significant difference in PrEP use, and those identifying as another race or ethnicity reported higher prevalence of past PEP use and lower current PrEP use. Past PEP use and current PrEP use were highest in the Northeast, with participants in the Midwest and South reporting significantly lower PEP and PrEP use. A significant interaction of Black race by past PEP use with current PrEP use was found (RRR 0.57, 99.9% CI 0.37-0.87), indicating that Black men who previously used PEP were less likely to report current PrEP use. Participants who reported recent club drug use were significantly more likely to report past PEP use and current or prior PrEP use than those without recent club drug use. PrEP use continues to be the predominant HIV prevention strategy for SMM compared with PEP use. Higher rates of past PEP use and current PrEP use among Black SMM are noteworthy, given the disproportionate burden of HIV. Nonetheless, understanding why Black men who previously used PEP are less likely to report current PrEP use is an important avenue for future research.

2085. PrEP Interest and Preferences Among US Black and Hispanic Men – A National Survey

Abstract Background Use of daily oral HIV pre-exposure prophylaxis (DO PrEP) has increased steadily in the past several years, but patterns of racial disparities have emerged in PrEP uptake. Although Black and Hispanic people are disproportionately affected by HIV in the US, they constitute a minority among those accessing DO PrEP. Newly available prevention options, such as long-acting injectable (LA) PrEP may help close the gap in unmet need for PrEP; however, interest in LA PrEP has not been evaluated specifically among racial/ethnic minority groups. Awareness, willingness, and usage of PrEP as well as HIV prevention preferences were assessed among sexually active adult men in the US. Methods Participants were recruited through a geographically targeted social media campaign and completed a self-administered, cross-sectional, online survey on demographics, sexual health and behavior, healthcare access, PrEP awareness and usage, and PrEP intention and preferences. Eligible participants met the following criteria: cisgender men, self-identified Black race and/or Hispanic ethnicity, 18 years or older, reporting unknown or HIV-negative status, currently residing in the US, and reporting anal or vaginal sex in the past six months. Descriptive statistics were calculated using SAS v9.4. Results From November to December 2021, 1365 men completed the survey (median age: 29.0 years; Black non-Hispanic: 43.1%, Black Hispanic: 40.3%, White Hispanic: 10.2%, Other Hispanic: 6.4%). A majority had heard of DO PrEP (66.6%) and LA PrEP (47.5%) as a way to prevent HIV; however, a smaller proportion had spoken to a healthcare provider (HCP) about PrEP (42.1%), had ever used PrEP (24.7%), or were currently taking PrEP (16.3%) (Figure 1). A large majority (74.0%) reported interest in using LA PrEP. When asked about their preferred PrEP option, 60.2% chose LA PrEP and 7.4% chose DO PrEP, while 27.5% stated that they preferred neither PrEP option. Figure 1.PrEP Awareness, Discussion with HCP, and Usage Among US Black and Hispanic Men, Overall and by Race/Ethnicity Conclusion Most participants demonstrated high awareness of PrEP and a strong interest in LA PrEP. The availability of and interest in LA PrEP may serve as an opportunity to help increase overall PrEP uptake among Black and Hispanic men in the US.

Incidence and Risk Factors for Low Birthweight and Preterm Birth in Post-Conflict Northern Uganda: A Community-Based Cohort Study.

Background: Annually, an estimated 20 million (13%) low-birthweight (LBW) and 15 million (11.1%) preterm infants are born worldwide. A paucity of data and reliance on hospital-based studies from low-income countries make it difficult to quantify the true burden of LBW and PB, the leading cause of neonatal and under-five mortality. We aimed to determine the incidence and risk factors for LBW and preterm birth in Lira district of Northern Uganda. Methods: This was a community-based cohort study, nested within a cluster-randomized trial, designed to study the effect of a combined intervention on facility-based births. In total, 1877 pregnant women were recruited into the trial and followed from 28 weeks of gestation until birth. Infants of 1556 of these women had their birthweight recorded and 1279 infants were assessed for preterm birth using a maturity rating, the New Ballard Scoring system. Low birthweight was defined as birthweight <2.5kg and preterm birth was defined as birth before 37 completed weeks of gestation. The risk factors for low birthweight and preterm birth were analysed using a multivariable generalized estimation equation for the Poisson family. Results: The incidence of LBW was 121/1556 or 7.3% (95% Confidence interval (CI): 5.4–9.6%). The incidence of preterm births was 53/1279 or 5.0% (95% CI: 3.2–7.7%). Risk factors for LBW were maternal age ≥35 years (adjusted Risk Ratio or aRR: 1.9, 95% CI: 1.1–3.4), history of a small newborn (aRR: 2.1, 95% CI: 1.2–3.7), and maternal malaria in pregnancy (aRR: 1.7, 95% CI: 1.01–2.9). Intermittent preventive treatment (IPT) for malaria, on the other hand, was associated with a reduced risk of LBW (aRR: 0.6, 95% CI: 0.4–0.8). Risk factors for preterm birth were maternal HIV infection (aRR: 2.8, 95% CI: 1.1–7.3), while maternal education for ≥7 years was associated with a reduced risk of preterm birth (aRR: 0.2, 95% CI: 0.1–0.98) in post-conflict northern Uganda. Conclusions: About 7.3% LBW and 5.0% PB infants were born in the community of post-conflict northern Uganda. Maternal malaria in pregnancy, history of small newborn and age ≥35 years increased the likelihood of LBW while IPT reduced it. Maternal HIV infection was associated with an increased risk of PB compared to HIV negative status. Maternal formal education of ≥7 years was associated with a reduced risk of PB compared to those with 0–6 years. Interventions to prevent LBW and PBs should include girl child education, and promote antenatal screening, prevention and treatment of malaria and HIV infections.

Clinical and programmatic outcomes of HIV-exposed infants enrolled in care at geographically diverse clinics, 1997-2021: A cohort study.

BackgroundAlthough 1·3 million women with HIV give birth annually, care and outcomes for HIV-exposed infants remain incompletely understood. We analyzed programmatic and health indicators in a large, multidecade global dataset of linked mother–infant records from clinics and programs associated with the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium.Methods and findingsHIV-exposed infants were eligible for this retrospective cohort analysis if enrolled at <18 months at 198 clinics in 10 countries across 5 IeDEA regions: East Africa (EA), Central Africa (CA), West Africa (WA), Southern Africa (SA), and the Caribbean, Central, and South America network (CCASAnet). We estimated cumulative incidences of DNA PCR testing, loss to follow-up (LTFU), HIV diagnosis, and death through 24 months of age using proportional subdistribution hazard models accounting for competing risks. Competing risks were transfer, care withdrawal, and confirmation of negative HIV status, along with LTFU and death, when not the outcome of interest. In CA and EA, we quantified associations between maternal/infant characteristics and each outcome. A total of 82,067 infants (47,300 EA, 10,699 CA, 6,503 WA, 15,770 SA, 1,795 CCASAnet) born from 1997 to 2021 were included. Maternal antiretroviral therapy (ART) use during pregnancy ranged from 65·6% (CCASAnet) to 89·5% (EA), with improvements in all regions over time. Twenty-four-month cumulative incidences varied widely across regions, ranging from 12·3% (95% confidence limit [CL], 11·2%,13·5%) in WA to 94·8% (95% CL, 94·6%,95·1%) in EA for DNA PCR testing; 56·2% (95% CL, 55·2%,57·1%) in EA to 98·5% (95% CL, 98·3%,98·7%) in WA for LTFU; 1·9% (95% CL, 1·6%,2·3%) in WA to 10·3% (95% CL, 9·7%,10·9%) in EA for HIV diagnosis; and 0·5% (95% CL, 0·2%,1·0%) in CCASAnet to 4·7% (95% CL, 4·4%,5·0%) in EA for death. Although infant retention did not improve, HIV diagnosis and death decreased over time, and in EA, the cumulative incidence of HIV diagnosis decreased substantially, declining to 2·9% (95% CL, 1·5%,5·4%) in 2020. Maternal ART was associated with decreased infant mortality (subdistribution hazard ratio [sdHR], 0·65; 95% CL, 0·47,0·91 in EA, and sdHR, 0·51; 95% CL, 0·36,0·74 in CA) and HIV diagnosis (sdHR, 0·40; 95% CL, 0·31,0·50 in EA, and sdHR, 0·41; 95% CL, 0·31,0·54 in CA). Study limitations include potential misclassification of outcomes in real-world service delivery data and possible nonrepresentativeness of IeDEA sites and the population of HIV-exposed infants they serve.ConclusionsWhile there was marked regional and temporal heterogeneity in clinical and programmatic outcomes, infant LTFU was high across all regions and time periods. Further efforts are needed to keep HIV-exposed infants in care to receive essential services to reduce HIV infection and mortality.

HIV incidence among men who have sex with men (MSM) in Metro Manila, the Philippines: A prospective cohort study 2014-2018.

The human immunodeficiency virus (HIV) epidemic in the Philippines has been driven by sexual transmission among men who have sex with men (MSM) over the past 2 decades. As the incidence of HIV infection among MSM has not been extensively evaluated, this study aimed to determine the incidence of HIV infections and the associated risk factors among MSM in Metro Manila, Philippines.This prospective cohort study was conducted in 2 community centers in Metro Manila, the Philippines, between March 2014 and December 2018. MSM who had anal or oral sex in the past 12 months, aged ≥18 years, and confirmed HIV-negative status were enrolled. Participants were followed up every 3 months with repeat HIV testing and assessment of HIV-related practices.Of the 708 MSM included in this study, a total of 59 HIV seroconversions occurred during the follow-up, resulting in an incidence of 2.7 (95% confidence interval: 2.1–3.5) per 100 patient-years. Multivariate risk regression analysis indicated that age (P = .002) and anal sex with a consensual male partner in the past 3 months (P = .039) were significantly associated with HIV infection.Our study has shown high rates of incident HIV infection among Filipino MSM. This demonstrates the need for effective HIV prevention, surveillance, treatment, and intervention strategies targeting this population.

Recent HIV Infection Among Men Who Have Sex with Men, Transgender Women, and Genderqueer Individuals with Newly Diagnosed HIV Infection in Zimbabwe: Results from a Respondent-Driven Sampling Survey.

In Africa, rapid testing for recent HIV infection (RTRI) is being scaled up; however, use of the recent infection testing algorithm (RITA), which uses viral load (VL) to confirm RTRI-recent infections, is not a widespread practice. We present results of recently acquired HIV infections among men who have sex with men (MSM), transgender women, and genderqueer (TGW/GQ) individuals with newly diagnosed HIV infection in Zimbabwe as per the national approach (RTRI) and applying a RITA. In 2019, 1,538 MSM and TGW/GQ in Harare and Bulawayo, Zimbabwe were recruited to participate in a biobehavioral survey using respondent-driven sampling. Consenting participants received HIV testing and all HIV-positive specimens were tested with the RTRI Asanté HIV-1 Rapid Recency Assay, and for VL and CD4 count. RTRI-recent participants with unsuppressed VL (≥1,000 copies/mL) were classified as RITA-recent. Descriptive statistics were used to summarize results among RTRI-recent and RITA-recent participants. Among those tested for HIV (1,511/1,538), 22.5% (340/1,511) tested positive and of those, 55.0% (187/340) self-reported an HIV-negative or unknown status. Among these, 8.6% (16/187) were classified as RTRI-recent and 91.4% (171/187) were classified as RTRI-long term. After accounting for VL, RITA-recency was 1.1% (2/187). Two of 16 (12.5%) RTRI-recent infections were RITA-recent. VL among RITA-recent cases were 9,052 copies/mL and 40,694 copies/mL and both had CD4 counts <500. Data highlight misclassification of recent infections among MSM and TGW/GQ with newly diagnosed HIV infection using RTRI. With the incorporation of VL, >85% of RTRI-recent cases were reclassified as RITA-long term. True characterization of recent infections may not be possible without VL testing, which remains challenging in resource-limited settings.

Risk factors associated with the severity of pneumonia in a cohort of hospitalized children in a rural setting

Objectives: Pneumonia remains a leading cause of death in South African children under 5 years of age. Known risk factors for pneumonia have been the focus of public health strategies to mitigate disease. This study aimed to determine whether adverse household environmental factors were associated with severe compared to non-severe pneumonia in children admitted to Worcester Provincial Hospital (WPH), South Africa. Materials and Methods: We conducted a case–control study at WPH from January 1st to December 31st, 2019, including children aged 0–59 months admitted with pneumonia. Using the WHO definition, children were categorized as having severe or non-severe pneumonia. Structured interviews with consenting primary caregivers were conducted in both groups on weekdays throughout the year to collect demographic, social, maternal, infant, and household factors. We compared the odds of adverse household environmental factors including tobacco smoke exposure, indoor smoke exposure, and overcrowding in children with severe compared to non-severe pneumonia. Results: A total of 305 children were included, 134 (43.9%) cases with severe pneumonia and 171 (56.1%) controls with non-severe pneumonia. Baseline characteristics of children, including age (median 6.9 months; IQR 2.5–17.5), appropriate nutritional status (81.6%; n = 249), and HIV unexposed and uninfected status (81.3%; n = 248), were similar between groups. Caregiver characteristics, including age (median 28 years; IQR 23–33), secondary schooling (71.2%, n = 217), and HIV negative status (81%, n = 247), were also comparable between groups. There was no association in univariable or multivariable analysis between severe pneumonia and adverse household environmental factors including tobacco smoke exposure (aOR 0.73; 95% CI 0.44–1.21), overcrowding (aOR 0.65, 95% CI 0.39–1.08), and indoor smoke exposure (aOR 2.85; 95% CI 0.89–9.09). However, children with severe pneumonia had at least 5 times greater odds (aOR 5.42; 95% CI 1.10–26.65) of living in a household with a pit latrine toilet compared to any other toilet than children with non-severe pneumonia. Conclusion: Few factors were found to be associated with pneumonia severity, except for living in a household with a pit latrine toilet. This may represent socioeconomic vulnerability and the risk associated with developing severe pneumonia.

Patient sexuality disclosure experience and associations with clinical sexual health outcomes among HIV-negative men who have sex with men in Mexico

Many men who have sex with men (MSM) do not disclose their sexuality to their healthcare provider, despite potential health benefits. Data from the 2017 Encuesta de Sexo Entre Hombres online survey of 13,277 HIV-negative or unknown status MSM in Mexico were used to explore MSM patients' sexuality disclosure experience on sexual health outcomes using multivariable Poisson models with robust variance estimation to estimate adjusted prevalence ratios (aPR). Sexual health outcomes included Hepatitis B (HepB) and human papillomavirus (HPV) vaccination, and lifetime and past year HIV testing. Overall, 53.9% (n/N) disclosed their sexuality to their healthcare provider, and of those 6.4%, 62.9%, and 30.7% reported a negative, neutral, or positive disclosure experience, respectively. In comparison to no disclosure, neutral and positive disclosure experiences were associated with HepB vaccination (aPR[95% Confidence Interval (95% CI)] = 1.17[1.09, 1.25], p < 0.001; aPR[95% CI] = 1.35[1.25, 1.46], p < 0.001, respectively) and positive disclosure experiences were associated with HPV vaccination (aPR[95% CI] = 1.46[1.24, 1.71], p < 0.001). Those who disclosed their sexual behavior were more likely than those who did not disclose their sexual behavior to have received an HIV test in their lifetime (negative: aPR[95% CI] = 1.51[1.43, 1.60], p < 0.001; neutral: aPR[95% CI] = 1.61[1.56, 1.66], p < 0.001; positive: aPR[95% CI] = 1.64[1.58, 1.69], p < 0.001) and an HIV test in the past year (negative: aPR[95% CI] = 1.89[1.70, 2.10], p < 0.001; neutral: aPR[95% CI] = 2.09[1.98, 2.20], p < 0.001; positive: aPR[95% CI] = 2.24[2.12, 2.37], p < 0.001). There is a need to implement trainings for healthcare providers that focus on sexual health risk assessments and creating a space that encourages MSM patients and healthcare providers to discuss sexual health.

Pediatrics HIV-positive status disclosure and its predictors in Ethiopia: a systematic review and meta-analysis.

IntroductionHIV-positive status disclosure for children is challenging for family members, guardians, and healthcare professionals. Disclosure is very challenging, particularly for children, yet no systematic synthesis of evidence accurately measures HIV-positive status disclosure in children. This systematic review and meta-analysis study aimed to quantify the national prevalence of pediatric HIV-positive status disclosure in Ethiopia and identify factors associated with HIV-positive status disclosure.MethodWe systematically searched PubMed, EMBASE, Web of Science databases, and google scholar for relevant published studies. Studies published in the English language and conducted with cohort, case-control, and cross-sectional designs were eligible for the review. The primary and secondary outcomes of the study were HIV-positive status disclosure and factors associated with HIV-positive status disclosure, respectively. The quality of the included studies was assessed using the Joanna Briggs Institute critical appraisal tools. A random effect- model was used to estimate the pooled prevalence of HIV-positive status disclosure. Heterogeneity and publication bias of included studies was determined using I2 and Egger’s test, respectively.ResultFrom 601 records screened, nine relevant studies consisting of 2,442 HIV-positive children were included in the analysis. The overall pooled prevalence of HIV-positive status disclosure among children living with HIV/AIDS in Ethiopia was 31.2% (95% CI [23.9–38.5]). HIV-negative status of caregivers (AOR: 2.01; 95% CI [1.28–3.18]), long duration on ART (greater than 5 years) (AOR: 3.2; 95% CI [1.77–5.78]) and older age of the child (>10 years) (AOR: 7.2; 95% CI [4.37–11.88]) were significantly associated with HIV-positive status disclosure.ConclusionLow prevalence of pediatric HIV-positive status disclosure was observed in Ethiopia. The longer duration of ART, the HIV-negative status of the caregiver, and older age greater than 10 years were the predictors of pediatric HIV-positive status disclosure. Health system leaders and policymakers shall design training and counseling programs for healthcare professionals and caregivers to enhance their awareness about HIV-positive status disclosure.Trial registrationThis review was registered under PROSPERO and received a unique registration number, CRD42019119049.

Determinants of Treatment Outcomes among Drug-Susceptible Tuberculosis Patients on Directly Observed Treatment Short-Course at Federal Medical Centre, Abeokuta, South-West, Nigeria

Background: Surveillance of tuberculosis treatment outcomes is very crucial in evaluating successes of tuberculosis (TB) intervention programmes as well as assessing progress towards achieving the Sustainable Development Goals target of ending TB infection by 2030. The study assessed treatment outcomes of tuberculosis and the determinants among tuberculosis patients on Directly Observed Treatment Short-course (DOTs) at Federal Medical Centre, Abeokuta South-West, Nigeria.&#x0D; Methods: This was a retrospective review of treatment outcomes of patients managed for Tuberculosis at the facility between January 2015 and December 2019. Data were retrieved from the treatment register and analysed using IBM® SPSS software version 23. Results were presented using frequencies and percentages, while the Chi-square test was used to test for association between the treatment outcomes and the independent variables. Binary logistics regression was used to assess for determinants of treatment outcomes at a level of significance of p&lt;0.05.&#x0D; Results: A total of 726 records were reviewed. The median age of the patients was 35.0 years (IQR 25). The treatment success rate (TSR) and cure rate were 83.2% and 43.7% respectively. TB patients with negative HIV status were about two times more likely to have successful treatment outcomes (OR=1.86, 95%CI=1.20-2.88).&#x0D; Conclusion: The TSR and cure rate obtained in this study were below the national targets set by the World Health Organization, and HIV co-infection was a threat to successful treatment outcomes among TB patients. Ensuring optimized antiretroviral therapy, prompt diagnosis and treatment of TB in HIV patients will go a long way in improving treatment outcomes.
