RESUMEN

BACKGROUND: Functional abdominal pain disorders (FAPD) are the most common chronic pain conditions of childhood and are made worse by co-occurring anxiety. Our research team found that the Aim to Decrease Pain and Anxiety Treatment (ADAPT), a six-session coping skills program using cognitive behavioral therapy strategies, was effective in improving pain-related symptoms and anxiety symptoms compared to standard care. In follow-up, this current randomized clinical trial (RCT) aims to test potential neural mechanisms underlying the effect of ADAPT. Specifically, this two-arm RCT will explore changes in amygdalar functional connectivity (primary outcome) following the ADAPT protocol during the water loading symptom provocation task (WL-SPT). Secondary (e.g., changes in regional cerebral blood flow via pulsed arterial spin labeling MRI) and exploratory (e.g., the association between the changes in functional connectivity and clinical symptoms) outcomes will also be investigated. METHODS: We will include patients ages 11 to 16 years presenting to outpatient pediatric gastroenterology care at a midwestern children's hospital with a diagnosis of FAPD plus evidence of clinical anxiety based on a validated screening tool (the Generalized Anxiety Disorder-7 [GAD-7] measure). Eligible participants will undergo baseline neuroimaging involving the WL-SPT, and assessment of self-reported pain, anxiety, and additional symptoms, prior to being randomized to a six-week remotely delivered ADAPT program plus standard medical care or standard medical care alone (waitlist). Thereafter, subjects will complete a post assessment neuroimaging visit similar in nature to their first visit. CONCLUSIONS: This small scale RCT aims to increase understanding of potential neural mechanisms of response to ADAPT. TRIAL REGISTRATION: ClinicalTrials.gov registration: NCT03518216.

RESUMEN

Motor neuron degeneration, the defining feature of amyotrophic lateral sclerosis (ALS), is a primary example of cell-type specificity in neurodegenerative diseases. Using isogenic pairs of induced pluripotent stem cells (iPSCs) harboring different familial ALS mutations, we assess the capacity of iPSC-derived lower motor neurons, sensory neurons, astrocytes, and superficial cortical neurons to capture disease features including transcriptional and splicing dysregulation observed in human postmortem neurons. At early time points, differentially regulated genes in iPSC-derived lower motor neurons, but not other cell types, overlap with one-third of the differentially regulated genes in laser-dissected motor neurons from ALS compared with control postmortem spinal cords. For genes altered in both the iPSC model and bona fide human lower motor neurons, expression changes correlate between the two populations. In iPSC-derived lower motor neurons, but not other derived cell types, we detect the downregulation of genes affected by TDP-43-dependent splicing. This reduction takes place exclusively within genotypes known to involve TDP-43 pathology.

RESUMEN

INTRODUCTION: Key and priority populations (with risk behaviours and health inequities) are disproportionately affected by HIV in Uganda. We evaluated the impact of an intensive case management intervention on HIV treatment outcomes in Kalangala District, predominantly inhabited by fisher folk and female sex workers. METHODS: This quasi-experimental pre-post intervention evaluation included antiretroviral therapy naïve adults aged ≥ 18 years from six health facilities in the pre-intervention (Jan 1, 2017-December 31, 2017) and intervention phase (June 13, 2018-June 30, 2019). The primary outcomes were 6-month retention and viral suppression (VS) before and after implementation of the intervention involving facility and community case managers who supported participants through at least the first three months of ART. We used descriptive statistics to compared the characteristics, overall outcomes (i.e., retention, lost to follow up, died), and VS of participants by phase, and used mixed-effects logistic regression models to determine factors associated with 6-month retention in care. Marginal (averaging over facilities) probabilities of retention were computed from the final multivariable model. RESULTS: We enrolled 606 and 405 participants in the pre-intervention and intervention phases respectively. Approximately 75% of participants were aged 25-44 years, with similar age and gender distributions among phases. Approximately 46% of participants in the intervention were fisher folk and 9% were female sex workers. The adjusted probability of 6-month retention was higher in the intervention phase, 0.83 (95% CI: 0.77-0.90) versus pre-intervention phase, 0.73 (95% CI: 0.69-0.77, p = 0.03). The retention probability increased from 0.59 (0.49-0.68) to 0.73 (0.59-0.86), p = 0.03 among participants aged 18-24 years, and from 0.75 (0.71-0.78) to 0.85 (0.78-0.91), p = 0.03 among participants aged ≥ 25 years. VS (< 1,000 copies/mL) was approximately 87% in both phases. CONCLUSIONS: After implementation of the case management intervention, we observed significant improvement in 6-month retention in all age groups of a highly mobile population of predominantly fisher folk.

RESUMEN

We used publicly available data to describe epidemiology, genomic surveillance, and public health and social measures from the first 3 COVID-19 pandemic waves in southern Africa during April 6, 2020-September 19, 2021. South Africa detected regional waves on average 7.2 weeks before other countries. Average testing volume 244 tests/million/day) increased across waves and was highest in upper-middle-income countries. Across the 3 waves, average reported regional incidence increased (17.4, 51.9, 123.3 cases/1 million population/day), as did positivity of diagnostic tests (8.8%, 12.2%, 14.5%); mortality (0.3, 1.5, 2.7 deaths/1 million populaiton/day); and case-fatality ratios (1.9%, 2.1%, 2.5%). Beta variant (B.1.351) drove the second wave and Delta (B.1.617.2) the third. Stringent implementation of safety measures declined across waves. As of September 19, 2021, completed vaccination coverage remained low (8.1% of total population). Our findings highlight opportunities for strengthening surveillance, health systems, and access to realistically available therapeutics, and scaling up risk-based vaccination.

RESUMEN

BACKGROUND: The estimated prevalence of neural tube defects (NTDs) in Africa is 11.7 per 10,000 live births; however, data on the impact of antiretroviral therapy (ART) during pregnancy and the risk for birth defects in Africa are limited. METHODS: Data from a hospital-based surveillance program at four hospitals in Kampala, Uganda were used to estimate the baseline prevalence of NTDs and assess potential associations with HIV status and ART use. All live births, stillbirths, and spontaneous abortions delivered at the participating hospitals affected with selected birth defects between August 2015 and December 2018 were included. Trained midwives collected data from hospital records, maternal interviews, photographs, and narrative descriptions of birth defects. We estimated NTD prevalence per 10,000 births (live, stillbirths, spontaneous abortions), prevalence ratios, and 95% confidence intervals (CIs). RESULTS: A total of 110,752 births from 107,133 women were included in the analysis; 9,394 (8.8%) women were HIV-infected and among those with HIV infection, 95.6% (n = 8,977) were on ART at delivery. Overall, 109 births were affected with NTDs, giving a prevalence of 9.8 (95% CI [8.2, 11.9]). Spina bifida (n = 63) was the most common type of NTD, with a prevalence of 5.7 (95% CI [4.4, 7.3]), followed by anencephaly (n = 31), with a prevalence of 2.8 (95% CI [2.0, 4.0]). CONCLUSION: The prevalence of NTDs among births in Kampala, Uganda is consistent with current estimates for Africa. With the continued introduction of new medications that may be taken during pregnancy, sustainable birth defect surveillance systems and pharmacovigilance are indicated.

RESUMEN

INTRODUCTION: Because of low pediatric HIV prevalence, more tests are needed to find 1 HIV-positive child compared with adults. In Uganda, the number needed to test (NNT) to find 1 new HIV-positive child was 64 in outpatient departments (OPDs) and 31 through index testing. We aimed to develop and validate a pediatric (1.5-14 years) screening tool to optimize testing approaches. METHODS: Phase 1 evaluated the performance of 10 screening questions in 14 OPDs using a variable selection algorithm to evaluate combinations of screening questions. Using logistic regression, we identified the number of screening questions with the best predictive accuracy using the receiver operation characteristic curve. Phase 2 validated the proposed tool in 15 OPDs and 7 orphan and vulnerable children programs. We estimated sensitivity, specificity, and NNT accounting for intercluster correlations. RESULTS: A total of 3482 children were enrolled. The optimal model included reported HIV-positive maternal status or 2/5 symptoms (sickly in the last 3 months, recurring skin problems, weight loss, not growing well, and history of tuberculosis). The proposed tool had sensitivity of 83.6% [95% confidence interval (CI): 68.1 to 92.4] and specificity of 62.5% (95% CI: 55.0 to 69.4). The tool was validated in a sample of 11,342 children; sensitivity was 87.8% (95% CI: 80.9 to 92.5) and specificity 62.6% (95% CI: 54.8 to 69.7) across OPDs and community sites. In OPDs, sensitivity was 88.1% (95% CI: 80.8 to 92.8) and specificity 69.0% (95% CI: 61.9 to 75.3). The NNT was 43 (95% CI: 28 to 67) across settings and 28 (95% CI: 20 to 38) for OPD. CONCLUSIONS: This HIV screening tool has high sensitivity and reasonable specificity, increasing testing efficiency and yield for children and adolescents.

RESUMEN

BACKGROUND: Uganda has one of the highest adolescent pregnancy rates in sub-Saharan Africa. We compared the risk of adverse birth outcomes between adolescents (age 12-19 years) and mothers (age 20-34 years) in four urban hospitals. METHODS: Maternal demographics, HIV status, and birth outcomes of all live births, stillbirths, and spontaneous abortions delivered from August 2015 to December 2018 were extracted from a hospital-based birth defects surveillance database. Differences in the distributions of maternal and infant characteristics by maternal age groups were tested with Pearson's chi-square. Adjusted odds ratios (aORs) and 95% confidence intervals (CI) were calculated using logistic regression to compare the prevalence of adverse birth outcomes among adolescents to mothers 20-34 years. RESULTS: A total of 100,189 births were analyzed, with 11.1% among adolescent mothers and 89.0% among older mothers. Adolescent mothers had an increased risk of preterm delivery (aOR: 1.14; CI 1.06-1.23), low birth weight (aOR: 1.46; CI 1.34-1.59), and early neonatal deaths (aOR: 1.58; CI 1.23-2.02). Newborns of adolescent mothers had an increased risk of major external birth defects (aOR: 1.33; CI 1.02-1.76), specifically, gastroschisis (aOR: 3.20; CI 1.12-9.13) compared to mothers 20-34 years. The difference between the prevalence of gastroschisis among adolescent mothers (7.3 per 10,000 births; 95% CI 3.7-14.3) was statistically significant when compared to mothers 20-34 years (1.6 per 10,000 births; 95% CI 0.9-2.6). CONCLUSIONS: This study found that adolescent mothers had an increased risk for several adverse birth outcomes compared to mothers 20-34 years, similar to findings in the region and globally. Interventions are needed to improve birth outcomes in this vulnerable population.


Adolescent pregnancies are a global problem occurring in high-, middle-, and low-income countries with Uganda having one of the highest adolescent pregnancy rates in sub-Saharan Africa. We compared the risk of adverse birth outcomes, including major external birth defects, between adolescents, (age 12­19 years) and mothers (age 20­34 years) in four urban hospitals.All informative births, including live births, stillbirths, and spontaneous abortions; regardless of gestational age, delivered at four selected hospitals in Kampala from August 2015 to December 2018 were examined. Demographic data were obtained by midwives through maternal interviews and review of hospital patient notes.Of the 100,189 births, 11.0% were among adolescent mothers and 89.0% among mothers (20­34 years). Adolescent mothers were more likely than mothers (20­34 years) to have an infant with preterm delivery, low birth weight, early neonatal death, and major external birth defects. Adolescent pregnancies were also associated with an increased risk of gastroschisis when compared to mothers (20­34 years).In conclusion, this study found that adolescent mothers had an increased risk for several adverse birth outcomes compared to mothers 20­34 years. Research on the potential underlying causes or mechanisms for these adverse outcomes among adolescent births is necessary to identify possible interventions.

RESUMEN

As countries strive to eliminate mother-to-child transmission of HIV, female sex workers (FSW) and their children still face barriers to accessing these essential services. Data on FSW uptake of HIV and reproductive health services before, during, and after pregnancy reveal inadequate service utilization. Stigma encountered by FSW in healthcare settings may contribute to low uptake of HIV testing, antiretroviral therapy (ART), and other prevention of mother-to-child HIV transmission (PMTCT) services. Coordination between community-based FSW and facility-based PMTCT programs can facilitate successful linkage of pregnant FSW to antenatal services to support PMTCT efforts. We offer a way forward to reach 90-90-90 targets for FSW and their families and eliminate mother-to-child transmission of HIV.

RESUMEN

BACKGROUND: Access to antiretroviral therapy (ART) has expanded in Haiti because of the adoption of Option B+ and the revision of treatment guidelines. Retention in care and treatment varies greatly and few studies have examined retention rates, particularly among women enrolled in Option B+. OBJECTIVE: To assess attrition among pregnant and non-pregnant patients initiating ART following adoption of Option B+ in Haiti. METHODS: Longitudinal data of adult patients initiated on ART from October 2012 through August 2014 at 73 health facilities across Haiti were analyzed using a survival analysis framework to determine levels of attrition. The Kaplan-Meier method and Cox proportional hazards regression were used to examine risk factors associated with attrition. RESULTS: Among 17,059 patients who initiated ART, 7627 (44.7%) were non-pregnant women, 5899 (34.6%) were men, and 3533 (20.7%) were Option B+ clients. Attrition from the ART program was 36.7% at 12 months (95% CI: 35.9-37.5%). Option B+ patients had the highest level of attrition at 50.4% at 12 months (95% CI: 48.6-52.3%). While early HIV disease stage at ART initiation was protective among non-pregnant women and men, it was a strong risk factor among Option B+ clients. In adjusted analyses, key protective factors were older age (p < 0.0001), living near the health facility (p = 0.04), having another known HIV-positive household member (p < 0.0001), having greater body mass index (BMI) (p < 0.0001), pre-ART counseling (p < 0.0001), and Cotrimoxazole prophylaxis during baseline (p < 0.01). Higher attrition was associated with rapidly starting ART after enrollment (p < 0.0001), anemia (p < 0.0001), and regimen tenofovir+lamivudine+nevirapine (TDF+3TC+NVP) (p < 0.001). CONCLUSIONS: ART attrition in Haiti is high among adults, especially among Option B+ patients. Identifying newly initiated patients most at risk for attrition and providing appropriate interventions could help reduce ART attrition.

RESUMEN

While the Interagency Task Team on the Prevention and Treatment of HIV Infection in Pregnant Women, Mothers, and Children (IATT) partnership existed before the Global Plan Towards the Elimination of New HIV Infections Among Children by 2015 and Keeping Their Mothers Alive (Global Plan), its reconfiguration was critical to coordinating provision of technical assistance that positively influenced country decision-making and program performance. This article describes how the Global Plan anchored the work of the IATT and, in turn, how the IATT's technical assistance helped to accelerate achievement of the Global Plan targets and milestones. The technical assistance that will be discussed addressed a broad range of priority actions and milestones described in the Global Plan: (1) planning for and implementing Option B+; (2) strengthening monitoring and evaluation systems; (3) translating evidence into action and advocacy; and (4) promoting community engagement. This article also reviews the ongoing challenges and opportunities of providing technical assistance in a rapidly evolving environment that calls for ever more flexible and contextualized responses. The effectiveness of technical assistance facilitated by the IATT was defined by its timeliness, evidence base, and unique global perspective that built on the competencies of its partners and promoted synergies across program areas. Reaching the final goal of eliminating vertical transmission of HIV infection and achieving an AIDS-free generation in countries with the highest HIV burden requires that the IATT partnership and technical assistance remain responsive to country-specific needs while aligning with the current programmatic reality and new global goals such as the Sustainable Development Goals and 90-90-90 targets.

RESUMEN

The Global Plan Towards the Elimination of New HIV Infections Among Children by 2015 and Keeping Their Mothers Alive (Global Plan), which was launched in 2011, set a series of ambitious targets, including a reduction of new HIV infections among children by 90% by 2015 (from a baseline year of 2009) and AIDS-related maternal mortality by 50% by 2015. To reach these targets, the Global Plan called for unprecedented investments in the prevention of mother-to-child transmission of HIV (PMTCT), innovative new approaches to service delivery, immense collective effort on the programmatic and policy fronts, and importantly, a renewed focus on data collection and use. We provide an overview of major achievements in monitoring and evaluation across Global Plan countries and highlight key challenges and innovative country-driven solutions using PMTCT program data. Specifically, we describe the following: (1) Uganda's development and use of a weekly reporting system for PMTCT using short message service technology that facilitates real-time monitoring and programmatic adjustments throughout the transition to a "treat all" approach for pregnant and breastfeeding women living with HIV (Option B+); (2) Uganda's work to eliminate parallel reporting systems while strengthening the national electronic district health information system; and (3) how routine PMTCT program data in Nigeria can be used to estimate HIV prevalence at the local level and address a critical gap in local descriptive epidemiologic data to better target limited resources. We also identify several ongoing challenges in data collection, analysis, and use, and we suggest potential solutions.

RESUMEN

OBJECTIVES: In October 2012, the Haitian Ministry of Health endorsed the "Option B+" strategy to eliminate mother-to-child transmission of HIV and achieve HIV epidemic control. The objective of this paper is to assess and identify risk factors for attrition from the national ART program among Option B+ patients in the 12 months after ART initiation. DESIGN: This retrospective cohort study included patients newly initiating ART from October 2012-August 2013 at 68 ART sites covering 45% of all newly enrolled ART patients in all regions of Haiti. METHODS: With data from electronic medical records, we carried out descriptive analysis of sociodemographic, clinical, and pregnancy-related correlates of ART attrition, and used a modified Poisson regression approach to estimate relative risks in a multivariable model. RESULTS: There were 2,166 Option B+ patients who initiated ART, of whom 1,023 were not retained by 12 months (47.2%). One quarter (25.3%) dropped out within 3 months of ART initiation. Protective factors included older age, more advanced HIV disease progression, and any adherence counseling prior to ART initiation, while risk factors included starting ART late in gestation, starting ART within 7 days of HIV testing, and using an atypical ART regimen. DISCUSSION: Our study demonstrates early ART attrition among Option B+ patients and contributes evidence on the characteristics of women who are most at risk of attrition in Haiti. Our findings highlight the importance of targeted strategies to support retention among Option B+ patients.

RESUMEN

BACKGROUND: Global guidelines recommend universal syphilis and HIV screening for pregnant women. Rapid syphilis testing (RST) may contribute toward achievement of universal screening. OBJECTIVES: To examine the impact of RST on syphilis and HIV screening among pregnant women. SEARCH STRATEGY: We searched MEDLINE for English- and non-English language articles published through November, 2014. SELECTION CRITERIA: We included studies that used a comparative design and reported on syphilis and HIV test uptake among pregnant women in low- and middle-income countries (LMICs) following introduction of RST. DATA COLLECTION AND ANALYSIS: Data were extracted from six eligible articles presenting findings from Asia, Africa, and Latin America. MAIN RESULTS: All studies reported substantial increases in antenatal syphilis testing following introduction of RST; the latter did not appear to adversely impact antenatal HIV screening levels at sites already offering rapid HIV testing and may increase HIV screening among pregnant women in some settings. Qualitative data revealed that women were highly satisfied with RST. Nevertheless, ensuring adequate training for healthcare workers and supplies of commodities were cited as key implementation barriers. CONCLUSIONS: RST may increase antenatal syphilis and HIV screening and contribute to the improvement of antenatal care in LMICs.

RESUMEN

Pediatricians in Africa requested a tool to improve caregiver dosing of liquid antiretroviral medication. We developed, evaluated and disseminated a clip to control the amount of medication drawn into an oral syringe. In a laboratory, a user tested clips of different lengths, corresponding to different volumes, by drawing water into a syringe with a clip. In Texas and Malawi, 149 adults attempted to measure Pepto-Bismol™ using a syringe with a clip, a syringe without a clip, and a dosing cup, in a randomly assigned order. In the laboratory, the volume of liquid, ranging from 1 to 4.5 mL, drawn into the syringe was always within at least 5 µL of the intended dose. In Texas, 84% of doses were accurate within ±10%, vs. 63% using the syringe alone, and 21% with the dosing cup. In Malawi, 98% of doses were accurate to within ±10%, vs. 90% using the syringe alone, and 27% with the dosing cup. For target accuracy values within ±45% (±21%), a significantly higher fraction of Houston (Kamangira) participants delivered an accurate dose using the syringe with the clip than with the syringe alone (p < 0.05). The clip enables a greater proportion of users to accurately measure liquid medication.

RESUMEN

In June 2011, the Joint United Nations Programme on HIV/AIDS, the US President's Emergency Plan for AIDS Relief (PEPFAR), and other collaborators outlined a transformative plan to virtually eliminate pediatric AIDS worldwide. The ambitious targets of this initiative included a 90% reduction in new pediatric HIV infections and a 50% reduction in HIV-related maternal mortality--all by 2015. PEPFAR has made an unprecedented commitment to the expansion and improvement of prevention of mother-to-child HIV transmission (PMTCT) services globally and is expected to play a critical role in reaching the virtual elimination target. To date, PEPFAR has been instrumental in the success of many national programs, including expanded coverage of PMTCT services, an enhanced continuum of care between PMTCT and HIV care and treatment, provision of more efficacious regimens for antiretroviral prophylaxis, design of innovative but simplified PMTCT approaches, and development of new strategies to evaluate program effectiveness. These accomplishments have been made through collaborative efforts with host governments, United Nations agencies, other donors (eg, the Global Fund for AIDS, Tuberculosis, and Malaria), nongovernmental organizations, and private sector partners. To successfully meet the ambitious global targets to prevent new infant HIV infections, PEPFAR must continue to leverage the existing PMTCT platform, while developing innovative approaches to rapidly expand quality HIV services. PEPFAR must also carefully integrate PMTCT into the broader combination prevention agenda for HIV, so that real progress can be made toward an "AIDS-free generation" worldwide.

RESUMEN

OBJECTIVE: The objective of this study was to explore the association between the Ten Steps of the Baby Friendly Hospital Initiative (BFHI) of the World Health Organization (Geneva, Switzerland) and breastfeeding at 2 days and 2 weeks. METHODS: A 65-question institutional survey assessing compliance with the Ten Steps was used to determine an overall breastfeeding Support Score for each of Oregon's 57 birthing hospitals. Hospital breastfeeding outcomes were obtained from the newborn metabolic screening forms. RESULTS: Hospitals' overall breastfeeding Support Scores ranged from 49.4 to 98.2 out of a possible total score of 100. Hospital compliance with individual Steps ranged from 5.3% for Step 2 (staff training) to 93% for Step 4 (helping with breastfeeding initiation) and Step 8 (encouraging feeding on demand). After controlling for institutional differences (by multivariate linear regression) we found that increases in overall hospital breastfeeding Support Scores were associated with increases in breastfeeding percentage at 2 days (p = 0.021) and at 2 weeks postpartum (p = 0.011). In analyzing each Step individually, however, only the presence of a written hospital policy was independently associated with breastfeeding percent (p = 0.028). CONCLUSIONS: This institutional-level evaluation corroborates previous findings demonstrating that increased implementation of the Ten Steps is associated with increased breastfeeding. Further, it suggests that hospitals with comprehensive breastfeeding policies are likely to have better breastfeeding support services and better breastfeeding outcomes. Hospitals may consider using these results to prioritize breastfeeding support services through development of hospital breastfeeding policies and to utilize institutional surveys as a component of breastfeeding quality improvement initiatives.

RESUMEN

Non-supine sleep position and parental tobacco use are known risk factors for sudden infant death syndrome (SIDS). Recent studies show that co-sleeping (bed sharing) slightly increases the overall risk of SIDS (strength of recommendation [SOR]: B) and is greatest for infants less than 11 weeks old (SOR: B). The relationship between bed sharing and SIDS is strongest for infants whose parents use tobacco (SOR: B). Infants who sleep in a room separate from their caregivers or on a couch or an armchair are at increased risk for SIDS (SOR: B). Using bedding accessories such as duvets or pillows may increase an infant's risk of SIDS (SOR: B).
