Effectiveness of an integrated multilevel early child development intervention on caregiver knowledge and behavior: a quasi-experimental evaluation of the Malezi program in Tanzania.

BACKGROUND: The quality of caregiving and the parent-child relationship is critical for early child development (ECD) and has been shown to be modifiable. This study evaluated an ECD project in Tanzania, assessing the effectiveness of radio messaging (RM) alone and a combined radio messaging/video job aids/ECD (RMV-ECD) intervention. METHODS: This two-arm pre-post evaluation study enrolled a cohort of caregivers of children 0-24 months in four districts of Tabora region, following them for 9 months. ECD radio messages were broadcast on popular stations at least 10 times/day reaching all study districts. In two districts, community health workers (CHW), trained in UNICEF's Care for Child Development package, used ECD videos in home- and facility-based sessions with caregivers. We used McNemar's testing (pre-post pairs) within intervention group to describe how the intervention was associated with change in five outcomes: ECD knowledge, early stimulation, father engagement, responsive care, and environment safety. Logistic regression was used to describe the relative benefits of the combined intervention package (RMV-ECD) compared to radio messaging (RM). RESULTS: In the RMV-ECD arm, all outcomes at endline except environment safety significantly improved after the intervention with the largest change seen in ECD knowledge (35.8% increase, p < .0001) and the smallest in father engagement (6.7%, p = .015). In the RM arm, ECD knowledge (5.7%, p = .031) and environment safety (18.1%, p = <.0001) improved. High measures of parenting stress were associated with lower likelihood of having good ECD knowledge (AOR 0.50, 95%CI: 0.35, 0.71), father engagement (AOR 0.72, 95%CI: 0.52, 0.99) and responsive care (AOR 0.31, 95%CI: 0.18, 0.54). CONCLUSIONS: An intervention that includes mass media, educational video content and CHWs who counsel caregivers in their homes and health facilities was associated with significant improvements in ECD parenting knowledge and behaviors but a relationship with responsive care could not be established. The less costly mass media-only intervention was associated with improved parenting knowledge and household environment safety. Parenting interventions targeting young children could be improved by incorporating more messaging and caregiver coaching in managing parental stress.

Male Pattern Baldness in Relation to Prostate Cancer-Specific Mortality: A Prospective Analysis in the NHANES I Epidemiologic Follow-up Study.

We used male pattern baldness as a proxy for long-term androgen exposure and investigated the association of dermatologist-assessed hair loss with prostate cancer-specific mortality in the first National Health and Nutrition Examination Survey Epidemiologic Follow-up Study. From the baseline survey (1971-1974), we included 4,316 men who were 25-74 years of age and had no prior cancer diagnosis. We estimated hazard ratios and used Cox proportional hazards regressions with age as the time metric and baseline hazard stratified by baseline age. A hybrid framework was used to account for stratification and clustering of the sample design, with adjustment for the variables used to calculate sample weights. During follow-up (median, 21 years), 3,284 deaths occurred; prostate cancer was the underlying cause of 107. In multivariable models, compared with no balding, any baldness was associated with a 56% higher risk of fatal prostate cancer (hazard ratio = 1.56; 95% confidence interval: 1.02, 2.37), and moderate balding specifically was associated with an 83% higher risk (hazard ratio = 1.83; 95% confidence interval: 1.15, 2.92). Conversely, patterned hair loss was not statistically significantly associated with all-cause mortality. Our analysis suggests that patterned hair loss is associated with a higher risk of fatal prostate cancer and supports the hypothesis of overlapping pathophysiological mechanisms.

Male pattern baldness in relation to prostate cancer risks: an analysis in the VITamins and lifestyle (VITAL) cohort study.

BACKGROUND: Male pattern baldness and prostate cancer may share common pathophysiological mechanisms in terms of advancing age, heritability, and endogenous hormones. Results from previous epidemiologic studies are inconsistent. Therefore, we investigated the association of prostate cancer risks with male pattern baldness at age 30 years, age 45 years, and baseline (median age = 60.5 years) in the VITamins And Lifestyle (VITAL) cohort study. METHODS: We included 32,583 men who were aged 50-76 years and without prior cancer diagnosis (excluding non-melanoma skin cancer) at the start of follow-up. First primary incident prostate cancers were ascertained via linkage to the western Washington Surveillance, Epidemiology, and End Results (SEER) program. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated using Cox proportional hazards regressions with adjustment for potential confounders. RESULTS: During follow-up (median = 9 years), 2,306 incident prostate cancers were diagnosed. Male pattern baldness at age 30 years, age 45 years, and baseline were not statistically significantly associated with overall or subtypes of prostate cancer. CONCLUSION: This study did not provide support for the hypothesis that male pattern baldness may be a marker for subsequent prostate cancer. Previous evidence indicates that a distinct class of frontal with vertex balding may be associated with increased risk of aggressive prostate cancer, but all such balding classes were captured as a single exposure category by the VITAL cohort questionnaire.

True durability: HIV virologic suppression in an urban clinic and implications for timing of intensive adherence efforts and viral load monitoring.

Although the majority of HIV-infected patients who begin potent antiretroviral therapy should expect long-term virologic suppression, the realities in practice are less certain. Durability of viral suppression was examined to define the best timing of targeted adherence strategies and intensive viral load monitoring in an urban clinic population with multiple challenges to ART adherence. We examined the risk of viral rebound for patients who achieved two consecutive viral loads lower than the lower limit of quantification (LLOQ) within 390 days. For 791 patients with two viral loads below the LLOQ, viral rebound >LLOQ from the first viral load was 36.9 % (95 % CI 32.2-41.6) in the first year, 26.9 % (95 % CI 21.7-32.1) in the year following one year of viral suppression, and 24.6 % (95 % CI 18.4-30.9) in the year following 2 years of viral suppression. However, for patients with CD4 ≥300 cells/µl who had 3-6 years of virologic suppression, the risk of viral rebound was very low. At the population level, the risk of viral rebound in a complex urban clinic population is surprisingly high even out to 3 years. Intensified monitoring and adherence efforts should target this high risk period. Thereafter, confidence in truly durable virologic suppression is improved.

Virological and care outcomes of community ART distribution: Experience with the PODI+ model in Kinshasa, Democratic Republic of the Congo.

INTRODUCTION: Differentiated service delivery models for HIV treatment can minimize unnecessary burdens on health systems and promote efficient delivery of antiretroviral therapy (ART). Under the PODI+ (poste de distribution communautaire) model, ART multi-month dispensation (MMD) was provided by lay workers (peers) in communities. We compared outcomes among clinically stable adults living with HIV receiving MMD via PODI+ or health facility (HF). METHODS: Clients receiving MMD at nine HFs and two PODI+ sites in Kinshasa were followed prospectively for one year (2018-2020). Medication possession ratio (MPR) was measured as proportion of total days with medication during the study through record abstraction at 3-month intervals. Viral load was assessed at enrollment and 12 months. We compared MPR and viral load suppression by arm and examined associations and potential confounders using unadjusted and adjusted odds ratios (AOR). Likert-style client satisfaction was collected during 12-month interviews and described by arm. RESULTS: Odds of maintaining viral load suppression at 12 months for PODI+ participants were two times that for HF participants. In adjusted models, PODI+ participants had 1.89 times the odds of being suppressed at 12 months compared to HF participants (95% CI: 1.10, 3.27). No significant differences in MPR were found between groups (OR: 0.86, 0.38-1.99). Older participants had significantly higher odds of MPR (AOR: 1.02, 95% CI: 1.01, 1.03) and viral suppression (AOR: 1.03, 95% CI: 1.00, 1.07). Satisfaction with services was ≥87% overall, but PODI+ participants rated time spent at site, provider attributes and other care aspects more favorably. CONCLUSIONS: Participants receiving MMD via peer-run community distribution points had similar MPR, but better virological outcomes and greater satisfaction with care than clinically similar participants receiving MMD through facilities. PODI+ could be a useful model for expansion to serve larger clinic populations from overburdened health facilities, particularly as policy shifts towards more inclusive MMD eligibility requirements.

Uptake, Acceptability, and Results of SARS-CoV-2 Antigen Rapid Diagnostic Testing in Community Settings in Cameroon.

Mass gathering event restrictions were part of mitigation measures during the COVID-19 pandemic that were lifted as prevalence decreased and after vaccination rollout. We explored SARS-CoV-2 antigen rapid diagnostic test acceptability and positivity in community settings in Cameroon. In August-October 2022, community workers sensitized and referred individuals for COVID-19 testing to nearby testing points in Douala and Yaoundé. Participants consented to SARS-CoV-2 antigen rapid diagnostic testing, a survey, or both components. We describe the positivity rate, COVID-19-related history, and Likert-scale testing perceptions. Factors associated with testing acceptance were analyzed using logistic regression. Overall, 20.5% (2,449/11,945) of sensitized individuals visited testing points, and 1,864 (76.1%) were enrolled; 50.6% accepted the survey and testing (46.0% accepted survey only). Seven (0.7%) of 1,006 individuals tested positive. Most (71.8%; 1,292/1,800) considered community testing more accessible than hospital-based testing. Individuals accepting versus refusing testing differed in perceived COVID-19 risk (67%, 49%; P <0.001), belief in accurate test results (79%, 47%; P <0.001), and ability to test easily (96%, 55%; P <0.001). Males (adjusted odds ratio [aOR]: 1.26 [1.04-1.53]) and those over 50 years (aOR: 1.9 [1.4-2.7]), with symptoms (aOR: 1.80 [1.30-2.50]), and at least partial vaccination (aOR: 0.76 [0.58-0.99]) were significantly associated with test acceptance. Refusal reasons included lack of perceived need for testing (33.8%) and testing discomfort (26.3%). Although community-based testing was generally perceived as important, actual testing uptake was low. In future pandemics, community testing should be optimized by addressing misinformation, offering alternative testing modalities for greater comfort, creating demand, and tailoring approaches to maximize testing uptake.

Is frequent CD4+ T-lymphocyte count monitoring necessary for persons with counts >=300 cells/µL and HIV-1 suppression?

Among patients infected with human immunodeficiency virus (HIV), those with HIV-1 RNA <200 copies/mL and CD4 counts ≥300 cells/µL had a 97.1% probability of maintaining durable CD4 ≥200 cells/µL for 4 years. When non-HIV causes of CD4 lymphopenia were excluded, the probability rose to 99.2%. Our data support less frequent CD4 monitoring during viral suppression.

Analyses of radiation and mesothelioma in the US Transuranium and Uranium Registries.

OBJECTIVES: We examined the relationship between radiation and excess deaths from mesothelioma among deceased nuclear workers who were part of the US Transuranium and Uranium Registries. METHODS: We performed univariate analysis with SAS Version 9.1 software. We conducted proportionate mortality ratio (PMR) and proportionate cancer mortality ratio (PCMR) analyses using the National Institute for Occupational Safety and Health Life Table Analysis System with the referent group being all deaths in the United States. RESULTS: We found a PMR of 62.40 (P < .05) and a PCMR of 46.92 (P < .05) for mesothelioma. PMRs for the 4 cumulative external radiation dose quartiles were 61.83, 57.43, 74.46, and 83.31. PCMRs were 36.16, 47.07, 51.35, and 67.73. The PMR and PCMR for trachea, bronchus, and lung cancer were not significantly elevated. CONCLUSIONS: The relationship between cumulative external radiation dose and the PMR and PCMR for mesothelioma suggests that external radiation at nuclear facilities is associated with an increased risk of mesothelioma. The lack of a significantly elevated PMR and PCMR for trachea, bronchus, and lung cancer suggests that asbestos did not confound this relationship.

Strengthening the Evidence: Similar Rates of Neural Tube Defects Among Deliveries Regardless of Maternal HIV Status and Dolutegravir Exposure in Hospital Birth Surveillance in Eswatini.

Birth defect surveillance in Eswatini in 2020-2021 identified 0.80% defects (197/24 599 live and stillborn infants). Neural tube defect (NTD) prevalence was 0.08%, 0.08%, and 0.15% for 4902 women on dolutegravir preconception, 17 285 HIV-negative women, and 1320 women on efavirenz preconception, respectively, more definitively refuting the dolutegravir preconception NTD safety signal.

Having health insurance does not eliminate race/ethnicity-associated delays in breast cancer diagnosis in the District of Columbia.

BACKGROUND: Delays in follow-up after breast cancer screening contribute to disparities in breast cancer outcomes. The objective of this research was to determine the impact of race/ethnicity and health insurance on diagnostic time, defined as number of days from suspicious finding to diagnostic resolution. METHODS: This retrospective cohort study of 1538 women examined for breast abnormalities between 1998-2010 at 6 hospitals/clinics in the District of Columbia measured mean diagnostic times between non-Hispanic whites (NHWs), non-Hispanic blacks (NHBs), and Hispanics with private, government, or no health insurance by using a full-factorial ANOVA model. RESULTS: Respective average--geometric mean (95% CI)--diagnostic times (in days) for NHWs, NHBs, and Hispanics were 16 (12, 21), 27 (23, 33), and 51 (35, 76) among privately insured; 12 (7, 19), 39 (32, 48), and 71 (48, 105) among government insured; 45 (17, 120), 60 (39, 92), and 67 (56, 79) among uninsured. Government insured NHWs had significantly shorter diagnostic times than government insured NHBs (P = .0003) and Hispanics (P < .0001). Privately insured NHWs had significantly shorter diagnostic times than privately insured NHBs (P = .03) and Hispanics (P < .0001). Privately insured NHBs had significantly shorter diagnostic times than uninsured NHBs (P = .03). CONCLUSIONS: Insured minorities waited >2 times longer to reach their diagnostic resolution than insured NHWs. Having private health insurance increased the speed of diagnostic resolution in NHBs; however, their diagnostic time remained significantly longer than for privately insured NHWs. These results suggest diagnostic delays in minorities are more likely caused by other barriers associated with race/ethnicity than by insurance status.

Factors Associated with Transition of HIV Care Readiness Among Adolescents and Youth from a Specialty Pediatric HIV Clinic in the United States.

Transitioning from pediatric to adult services is known to be associated with worsening of health outcomes and decreased retention in care among adolescents and youth living with HIV (AYLHIV). We aimed to identify factors associated with HIV care transition readiness among AYLHIV in care at a pediatric HIV clinic in Washington, DC. This retrospective cohort study from June 2019 through January 2021 collected demographic and clinical characteristics from the clinic database. We adapted the Transition Readiness Assessment Questionnaire (TRAQ; scored 1-4; 1 being the lowest level of preparedness) to evaluate transition readiness over time. We analyzed data using two-sided unadjusted two-sample and paired t-tests and adjusted analysis of variance (ANOVA). We included 103 AYLHIV (50.49% female; 100% non-Hispanic Black/African American; mean age = 19.54 ± 2.78 years; 81.55% virally suppressed). Mean baseline TRAQ score (2.32 ± 0.78) was associated with age (p < 0.0001), gender (p = 0.033), mode of HIV transmission (p = 0.0005), viral suppression (p = 0.0033), and duration of HIV diagnosis (p = 0.012). AYLHIV diagnosed with HIV within the prior year experienced significantly greater mean improvement in transition readiness compared with those living with HIV for >10 years (p = 0.013). Adjusted for covariates, older age (p < 0.0001), undetectable viral load (p = 0.0008), and presence of mental health condition(s) (p = 0.020) were associated with higher TRAQ scores. Lower improvement in transition readiness among youth with a longer history of HIV suggests that AYLHIV with perinatally acquired HIV might require additional support than those with horizontally acquired HIV.

Changes in cerebral tissue oxygenation and fractional oxygen extraction with gestational age and postnatal maturation in preterm infants.

OBJECTIVE: This study examined the correlation of cerebral tissue oxygen saturation (SctO2) and cerebral tissue fractional oxygen extraction (cFTOE) with gestational age (GA) and postnatal age over the first 28 days of life. STUDY DESIGN: Preterm infants with birth weight (BW) <1500 g were monitored with near-infrared spectroscopy (NIRS) during the first 28 days of life. SctO2 and cFTOE measurements were analyzed using a linear mixed model. RESULTS: A total of 70 preterm infants were included. Mean SctO2 decreased with increasing GA; SctO2 was 76.4% and 74.6% in the first 24 h for infants 24 and 28-week GA, respectively. For infants born at 24 and 28 it decreased to 52.9% and 58.4% at 28 days of life, respectively. cFTOE increased with increasing GA and postnatal age. CONCLUSIONS: There is an inverse relationship between SctO2 and gestational age and postnatal age but a direct relationship between cFTOE with GA and postnatal age.

Adverse Pregnancy Outcomes Among HIV-positive Women in the Era of Universal Antiretroviral Therapy Remain Elevated Compared With HIV-negative Women.

BACKGROUND: Without treatment, HIV infection in pregnant women is associated with adverse pregnancy outcomes. We compared adverse pregnancy outcomes among HIV-positive women on antiretroviral therapy (ART) and HIV-negative women who enrolled for antenatal care in selected health facilities in Maseru district, Lesotho. METHODS: We enrolled a cohort of HIV-positive and HIV-negative women at their first antenatal visit and followed them through delivery. Study data on miscarriage, stillbirth, preterm birth, low birth weight and birth defects were collected through participant interviews and medical record abstraction. We used the Rao-Scott χ2 test and the t test to assess differences in characteristics and outcomes between HIV-positive and HIV-negative women and generalized estimating equations for multivariable analysis. RESULTS: A total of 614 HIV-positive and 390 HIV-negative pregnant women were enrolled in the study with delivery information on 571 (93.1%) and 352 (90.3%) respectively. In the delivery cohort, the median age at enrolment was 28 years for HIV-positive women and 23 years for HIV-negative women with median gestational ages of 20 and 21 weeks, respectively. A total of 149 singleton pregnancies had documented adverse pregnancy outcomes; 33 (9.6%) HIV-negative pregnancies and 116 (20.6%) HIV-positive pregnancies. Compared with their HIV-negative counterparts, HIV-positive women were more likely to experience an adverse pregnancy outcome, adjusted odds ratio (AOR) 2.6 [95% confidence interval (CI): 1.71-3.97]; an intrauterine death (miscarriage or stillbirth), AOR 2.64 [95% CI: 1.25-5.49]; or a low birth weight delivery, AOR 1.89 [95% CI: 1.16-3.09]. CONCLUSION: Adverse pregnancy outcomes remained 2-3 times higher among HIV-positive women compared with HIV-negative women despite universal ART.

10-year follow-up of diabetes incidence and weight loss in the Diabetes Prevention Program Outcomes Study.

BACKGROUND: In the 2.8 years of the Diabetes Prevention Program (DPP) randomised clinical trial, diabetes incidence in high-risk adults was reduced by 58% with intensive lifestyle intervention and by 31% with metformin, compared with placebo. We investigated the persistence of these effects in the long term. METHODS: All active DPP participants were eligible for continued follow-up. 2766 of 3150 (88%) enrolled for a median additional follow-up of 5.7 years (IQR 5.5-5.8). 910 participants were from the lifestyle, 924 from the metformin, and 932 were from the original placebo groups. On the basis of the benefits from the intensive lifestyle intervention in the DPP, all three groups were offered group-implemented lifestyle intervention. Metformin treatment was continued in the original metformin group (850 mg twice daily as tolerated), with participants unmasked to assignment, and the original lifestyle intervention group was offered additional lifestyle support. The primary outcome was development of diabetes according to American Diabetes Association criteria. Analysis was by intention-to-treat. This study is registered with ClinicalTrials.gov, number NCT00038727. FINDINGS: During the 10.0-year (IQR 9.0-10.5) follow-up since randomisation to DPP, the original lifestyle group lost, then partly regained weight. The modest weight loss with metformin was maintained. Diabetes incidence rates during the DPP were 4.8 cases per 100 person-years (95% CI 4.1-5.7) in the intensive lifestyle intervention group, 7.8 (6.8-8.8) in the metformin group, and 11.0 (9.8-12.3) in the placebo group. Diabetes incidence rates in this follow-up study were similar between treatment groups: 5.9 per 100 person-years (5.1-6.8) for lifestyle, 4.9 (4.2-5.7) for metformin, and 5.6 (4.8-6.5) for placebo. Diabetes incidence in the 10 years since DPP randomisation was reduced by 34% (24-42) in the lifestyle group and 18% (7-28) in the metformin group compared with placebo. INTERPRETATION: During follow-up after DPP, incidences in the former placebo and metformin groups fell to equal those in the former lifestyle group, but the cumulative incidence of diabetes remained lowest in the lifestyle group. Prevention or delay of diabetes with lifestyle intervention or metformin can persist for at least 10 years. FUNDING: National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).

Active pediatric HIV case finding in Kenya and Uganda: A look at missed opportunities along the prevention of mother-to-child transmission of HIV (PMTCT) cascade.

BACKGROUND: Children living with HIV remain undiagnosed due to missed opportunities along the prevention of mother-to-child HIV transmission cascade. This study addresses programmatic gaps in the cascade by describing pregnancy and HIV-related services received by mothers of children newly identified as HIV-positive through active case finding. METHODS: This was a prospective observational cohort (2017-2018) of HIV-positive children <15 years of age newly diagnosed at study facilities and/or surrounding communities in Kenya and Uganda. At enrollment, caregivers were interviewed about maternal and child health and HIV history. Child medical and laboratory information was abstracted at two months post-diagnosis. Descriptive summary statistics were calculated; associations between selected factors and child age at HIV diagnosis were evaluated using generalized estimating equations. RESULTS: 174 HIV-positive children (median age 2.4 years) were enrolled. Among maternal caregivers, 110/132 (83.3%) attended antenatal care and 60 (45.5%) reported testing HIV-negative in antenatal care. Of 41 and 56 women known to be HIV-positive during pregnancy and breastfeeding respectively, 17 (41.5%) and 15 (26.8%) did not receive antiretroviral drugs. Despite known maternal HIV-positive status during pregnancy, 39% of these children were not diagnosed until after two years of age; children were diagnosed at younger ages in Uganda (p = 0.0074) and if mother was the caregiver (p<0.0001). The most common HIV testing points identifying children were outpatient (44.3%) and maternal/child health departments (29.9%). Nearly all children initiated antiretroviral therapy within two weeks of diagnosis. CONCLUSIONS: Multiple missed opportunities for HIV prevention and delays in HIV testing of HIV-exposed children were identified in newly diagnosed children. Findings support critical prevention messaging and retesting of HIV-negative women during pregnancy and breastfeeding, strengthening HIV treatment initiation and follow-up systems and interventions to ensure HIV-positive women receive lifelong antiretroviral therapy throughout the cascade, and broader implementation of community case finding so children not engaged in care receive testing services.

Small-area spatial-temporal changes in pre-exposure prophylaxis (PrEP) use in the general population and among men who have sex with men in the United States between 2012 and 2018.

PURPOSE: Oral emtricitabine/tenofovir disoproxil fumarate was approved for use as pre-exposure prophylaxis (PrEP) by the U.S. Food and Drug Administration in 2012. We used national pharmacy data to examine trends of PrEP use in U.S. counties from 2012 to 2018. METHODS: Using multi-level small-area spatio-temporal modeling, we calculated the estimated annual percentage change (EAPC) in prevalence of PrEP use in the general population from 2012 to 2018. We also used a proxy measure for prevalence of PrEP use among men who have sex with men (MSM) to evaluate trends of use among MSM, the PrEP use-to-MSM ratio (PmR) or number of male PrEP users per 1000 MSM population. RESULTS: The prevalence of PrEP use and PmR increased (EAPC range: (+26.9%, +71.0%) and (+28.4%, +158.7%), respectively) in all counties with varying magnitude of increase. Counties of the Midwest and the upper South and upper West had the slowest increase in prevalence of PrEP use (EAPC range: (+26.9%; +52.9%)). Counties of the northern part of the South had the lowest PmR (EAPC range: (+28.4%; +76.0%)). Counties of the most populous core-based statistical areas had a relatively faster increase in population prevalence of PrEP use but slower increase in PmR. CONCLUSIONS: All counties in the U.S. have witnessed an increase in PrEP use with important geographic variabilities. Identifying areas with slow improvement in PrEP use, as well as "model counties" with the fastest pace of progress in PrEP coverage, is critical to inform local and state-level policies and program evaluation for PrEP scale up, particularly among MSM at higher risk for HIV.

Hookworm, Ascaris lumbricoides infection and polyparasitism associated with poor cognitive performance in Brazilian schoolchildren.

OBJECTIVE: To investigate the relationship between hookworm and Ascaris lumbricoides infection and performance on three subsets of the Wechsler Intelligence Scale for Children - third edition (WISC-III) (Digit Span, Arithmetic and Coding) and Raven Colored Progressive Matrices. METHODS: Cross-sectional study of 210 children between the ages of 6 and 11 years in Americaninhas, Minas Gerais, Brazil. Separate proportional odds models were used to measure the association between the intensity of helminth infections and poor performance on each of the four cognitive tests. RESULTS: After adjusting for sex, age, socioeconomic status and other helminth infections, moderate-to-high-intensity hookworm infection was associated with poor performance on the WISC-III Coding subtest [OR = 3.20; 95% confidence interval (CI) = 1.43-7.17], low intensity of hookworm infection was associated with poor performance on the WISC-III Coding subtest [odds ratio (OR) = 3.71; 95% CI = 1.80-7.66] and moderate-to-high-intensity A. lumbricoides infection was associated with poor performance on the Raven test (OR = 2.03; 95% CI = 1.04-3.99), all in comparison with uninfected children. Children co-infected with A. lumbricoides infection and hookworm infection had greater odds of poor performance on some WISC-III subtests than children with only A. lumbricoides infection. CONCLUSIONS: These findings suggest that hookworm infection may be associated with poorer concentration and information processing skills, as measured on the WISC-III Coding subtest, and that A. lumbricoides infection may be associated with poorer general intelligence, as measured through the Raven Colored Progressive Matrices. This study also presents evidence that polyparasitized children experience worse cognitive outcomes than children with only one helminth infection.

24-month HIV-free survival among infants born to HIV-positive women enrolled in Option B+ program in Kigali, Rwanda: The Kabeho Study.

Lifelong antiretroviral therapy (ART) provision to all pregnant HIV-positive women ("Option B+") has been recommended by the World Health Organization since 2013, but there remain limited data on the effects of Option B+ on long-term HIV-free survival in breastfeeding HIV-exposed infants. The Kigali Antiretroviral and Breastfeeding Assessment for the Elimination of HIV (Kabeho) study enrolled HIV-positive women from the third trimester of pregnancy to 2 weeks postpartum in 14 heath facilities implementing Option B+ in Kigali, Rwanda. Mother-child pairs in the longitudinal observational cohort were followed until 24 months postpartum, with HIV diagnostic testing at 6 weeks, and 9, 18 and 24 months. The Kaplan-Meier method was used to estimate HIV transmission, survival, and HIV-free survival through 24 months. We enrolled 608 HIV-positive women in 2013-2014; birth outcome data were available for 600 women and 597 live-born infants. By 6 weeks, 11 infants had died and 3 infants had confirmed HIV infection (0.5% transmission; 95% confidence interval [CI] 0.2-1.6). At 9 months, there were 9 additional deaths and 2 new infections (cumulative transmission 0.9%, 95% CI 0.4-2.2). At 18 months, there were 6 additional deaths and no new infant infections. At 24 months, there were no additional child deaths and 1 new infection (cumulative 2.2%, 95% CI 0.7-7.0), for an overall 24-month HIV-free survival of 93.2% (95% CI 89.5-95.6). Low transmission rates and high HIV-free survival at 24 months were achieved in breastfeeding infants of HIV-positive mothers receiving universal ART in urban health facilities in Rwanda, though vigilance on maintaining viral suppression for ART-experienced women is needed.

Understanding Antiretroviral Treatment Adherence Among HIV-Positive Women at Four Postpartum Time Intervals: Qualitative Results from the Kabeho Study in Rwanda.

As lifelong antiretroviral therapy (ART) for pregnant women is implemented, it is important to understand the attitudes and norms affecting women's postpartum ART adherence. This is a qualitative cross-sectional study of HIV-positive postpartum women (n = 112) enrolled in a 2-year observational prospective cohort in Rwanda. Informed by the Theory of Reasoned Action (TRA), we conducted in-depth interviews with women whose children were 0-6, 7-12, 13-18, or 21-24 months of age to describe factors contributing to adherence and changes over time. Positive ART attitudes reported by women included mothers' health promotion, prevention of infant HIV infection, higher CD4 count, and improved physical appearance. Negative attitudes were few, but included side effects and the lifelong nature of treatment. Learning from people living with HIV (PLHIV) was identified as a norm facilitating adherence; ART adherence was inhibited by fear of disclosure or stigmatization in communities and clinics. Poor adherence behaviors were common immediately after HIV diagnosis, not necessarily during prevention of mother-to-child transmission (PMTCT). Women with older children, most of whom stopped breastfeeding by 13-18 months, reported more barriers and missed doses than women with younger children.
