RESUMEN

BACKGROUND: One-fifth of the global population is infected with soil-transmitted helminths (STH). Mass drug administration (MDA) with deworming medication is widely implemented to control morbidity associated with STH infections. However, surveillance of human infection prevalence by collecting individual stool samples is time-consuming, costly, often stigmatized, and logistically challenging. Current methods of STH detection are poorly sensitive, particularly in low-intensity and low-prevalence populations. METHODOLOGY/PRINCIPAL FINDINGS: We aimed to develop a sensitive and specific molecular method for detecting STH DNA in large volumes of soil (20 g) by conducting laboratory and proof of concept studies across field sites in Kenya, Benin, and India. We collected human stool (n = 669) and soil (n = 478) from 322 households across the three study sites. We developed protocols for DNA extraction from 20 g of soil and qPCR to detect Ascaris lumbricoides, Trichuris trichiura, Necator americanus, and Ancylostoma duodenale. Agreement between detection of STH via qPCR, digital droplet PCR (ddPCR), and microscopy-based methods was assessed using the Cohen's Kappa statistic. Finally, we estimated associations between soil characteristics and detection of STH in soil by qPCR, as well as between STH detected in soil and STH detected in stool from matched households, adjusting for soil characteristics. The overall prevalence of STH in soil by qPCR was 31% for A. lumbricoides, 3% for T. trichiura, and 13% for any hookworm species. ddPCR and qPCR performed similarly. However, there was poor agreement between STH detected in soil by qPCR versus light microscopy. Microscopy underestimated the prevalence of A. lumbricoides and N. americanus and overestimated T. trichiura. Detection of an STH species in household soil was strongly associated with increased odds of a household member being infected with that same species. CONCLUSIONS/SIGNIFICANCE: Soil surveillance for STH has several benefits over stool-based surveillance, including lower cost and higher success rates for sample collection. Considering that delivery of MDA occurs at the community level, environmental surveillance using molecular methods could be a cost-effective alternate strategy for monitoring STH in these populations.

RESUMEN

Objectives: To describe and compare liver mitochondrial and peroxisomal histopathology by nutritional status in children who died following hospitalization for acute illness in Malawi. Methods: Liver tissue was collected using Minimally Invasive Tissue Sampling from eleven children under-five years old who died during hospitalization and were either non-wasted (n = 4), severely wasted (n = 4) or had edematous malnutrition (n = 3). Histology was assessed on hematoxylin and eosin stained slides. Mitochondrial and peroxisomal ultrastructural features were characterized using electron microscopy (EM) and immunofluorescence (IF). Results: Hepatic steatosis was present in 50 % of non-wasted and severely wasted children and all children with edematous malnutrition. Edematous malnutrition was associated with 56 % and 45 % fewer mitochondria than severe wasting (p < 0.001) and no wasting (p = 0.006), respectively, and abnormal mitochondrial morphology compared to severe wasting (p = 0.002) and no wasting (p = 0.035). Peroxisomal abundance was reduced in edematous malnutrition compared to severe wasting (p = 0.005), but did not differ from no-wasting. Conclusion: Edematous malnutrition is associated with reduced abundance and altered morphology of hepatic mitochondria and peroxisomes. Interventions targeting improvements in hepatic metabolic function may be beneficial in improving metabolism and reducing mortality in children with severe malnutrition, particularly in those with nutritional edema.

RESUMEN

Despite the large number of children in India, there is little information on the impact of children's disability on school enrolment, and how this differs by population. We estimated the prevalence of childhood disability in two sites in Tamil Nadu, southern India, and the effect of functional difficulty on school enrolment. We used a parent-reported survey containing the UNICEF-Washington Group questions to identify children aged 5 to 17 years with functional difficulty during a census conducted for an ongoing trial. We estimated pooled- and gender-specific prevalence of functional difficulty among 29,044 children. We fitted regression models to identify subgroups with higher rates of functional difficulty and the effect of functional difficulty on reported school enrolment. We estimated the modification of the effect of functional difficulty by age, gender, socioeconomic status, household education, and sub-site, on additive and multiplicative scales. We found of 29,044 children, 299 (1.0%) had any functional difficulty, equal among boys and girls. Being understood (0.5%) and walking (0.4%) were the most common difficulties. Functional difficulty was strongly associated with non-enrolment in school (Prevalence ratio [PR] 4.59, 95% CI: 3.87, 5.43) after adjusting for age, gender, and site. We show scale-dependent differences between age and socioeconomic groups in the effect of functional difficulty on enrolment. This study shows that at least one in a hundred children in this region have severe functional difficulties and nearly half of these children are not enrolled in school, highlighting the need for further efforts and evidence-based interventions to increase school enrolment among these groups.

RESUMEN

BACKGROUND: School-based approaches are an efficient mechanism for the delivery of basic health services, but may result in the exclusion of children with disabilities if they are less likely to participate in schooling. Community-based 'door to door' approaches may provide a more equitable strategy to ensure that children with disabilities are reached, but disability is rarely assessed rigorously in the evaluation of health interventions. OBJECTIVES: To describe the prevalence and factors associated with disability among children aged 5-17 years and to assess the relative effectiveness of routine school-based deworming (SBD) compared with a novel intervention of community-based deworming (CBD) in treating children with disabilities for soil-transmitted helminths. SETTING: DeWorm3 Malawi Site (DMS), Mangochi district, Malawi. PARTICIPANTS: All 44 574 children aged 5-17 years residing within the DMS. PRIMARY AND SECONDARY OUTCOME MEASURES: Disability was defined as a functional limitation in one or more domains of the Washington Group/UNICEF Child Functioning Module administered as part of a community-based census. Treatment of all children during SBD and CBD was independently observed and recorded. For both intervention types, we performed bivariate analyses (z-score) of the absolute proportion of children with and without disabilities treated (absolute differences (ADs) in receipt of treatment), and logistic regression to examine whether disability status was associated with the likelihood of treatment (relative differences in receipt of treatment). RESULTS: The overall prevalence of disability was 3.3% (n=1467), and the most common domains of disability were hearing, remembering and communication. Boys were consistently more likely to have a disability compared with girls at all age groups, and disability was strongly associated with lower school attendance and worse levels of education. There was no significant difference in the proportion of children with disabilities treated during SBD when assessed by direct observation (-1% AD, p=0.41) or likelihood of treatment (adjusted risk ratio (aRR)=1.07, 95% CI 0.89 to 1.28). Treatment of all children during CBD was substantially higher than SBD, but again showed no significant difference in the proportions treated (-0.5% AD, p=0.59) or likelihood of treatment (aRR=1.04, 95% CI 0.99 to 1.10). CONCLUSION: SBD does not appear to exclude children with disabilities, but the effect of consistently lower levels of educational participation of children with disabilities should be actively considered in the design and monitoring of school health interventions. TRIAL REGISTRATION NUMBER: NCT03014167.

RESUMEN

INTRODUCTION: Despite significant progress over past decades, neonatal and infant morbidity and mortality remain unacceptably high in Ethiopia. Simple interventions have been shown to improve the health of children and reduce mortality. These include promotion of exclusive breast feeding for the first 6 months of life, immunisation and utilisation of available newborn healthcare services, which are proven to improve newborn survival. This study aims to determine the impact of a behaviour change intervention that partners Orthodox priests with volunteer community health workers, known in Ethiopia as the Health Development Army and trains them to conduct newborn health outreach to improve care seeking, uptake of key interventions and identification of sick infants. METHODS: The study designed is a community-randomised trial conducted in the Central Gondar area. The behaviour change intervention pairs trained Orthodox priests with members of the Health Development Army to conduct community health outreach by identifying near-term pregnant women in their communities and educating them on the topics of exclusive breast feeding, immunisation, nutrition and uptake of available child healthcare services. The evaluation of the intervention will enrol up to 150 newborn-mother pairs from communities receiving the behaviour change intervention and another 150 pairs enrolled from control communities. The quantitative analysis will be done by comparing data between the intervention and control groups related to breast feeding, anthropometry, immunisation status and uptake of child health services. The primary outcomes are exclusive breastfeeding through 6 months, mid-upper arm circumference, completion of vaccinations and infant hospitalisation. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the University of Washington (STUDY00006942) and the University of Gondar (No.V/P/RCS/05/2523/2019) Institutional Review Boards. Oral consent was obtained for the formative study, whereas written consent (or witnessed thumbprint) will be obtained from all enrolled mothers. Results will be communicated to community members, relevant government agencies and other stakeholders. TRIAL REGISTRATION NUMBER: NCT05111899.

RESUMEN

INTRODUCTION: Children with moderate or severe wasting are at particularly high risk of recurrent or persistent diarrhoea, nutritional deterioration and death following a diarrhoeal episode. Lactoferrin and lysozyme are nutritional supplements that may reduce the risk of recurrent diarrhoeal episodes and accelerate nutritional recovery by treating or preventing underlying enteric infections and/or improving enteric function. METHODS AND ANALYSIS: In this factorial, blinded, placebo-controlled randomised trial, we aim to determine the efficacy of lactoferrin and lysozyme supplementation in decreasing diarrhoea incidence and improving nutritional recovery in Kenyan children convalescing from comorbid diarrhoea and wasting. Six hundred children aged 6-24 months with mid-upper arm circumference <12.5 cm who are returning home after an outpatient visit or inpatient hospital stay for diarrhoea will be enrolled. Children will be randomised to 16 weeks of lactoferrin, lysozyme, a combination of the two, or placebo and followed for 24 weeks, with biweekly home visits by community health workers and clinic visits at 4, 10, 16 and 24 weeks. The primary analysis will compare the incidence of moderate-to-severe diarrhoea and time to nutritional recovery between each intervention arm and placebo. The trial will also test whether these interventions reduce enteric pathogen carriage, decrease enteric permeability and/or increase haemoglobin concentration in enrolled children. Finally, we will evaluate the acceptability, adherence and cost-effectiveness of lactoferrin and/or lysozyme. ETHICS AND DISSEMINATION: The trial has been approved by the institutional review boards of the Kenya Medical Research Institute, the University of Washington, the Kenyan Pharmacy and Poisons Board, and the Kenyan National Commission on Science, Technology and Innovation. The results of this trial will be shared with local and international stakeholders and published in peer-reviewed journals, and the key findings will be presented at relevant conferences. TRIAL REGISTRATION NUMBER: NCT05519254, PACTR202108480098476.

RESUMEN

Children are not born equal in their likelihood of survival. The risk of mortality is highest during and shortly after birth. In the immediate postnatal period and beyond, perinatal events, nutrition, infections, family and environmental exposures, and health services largely determine the risk of death. We argue that current public health programmes do not fully acknowledge this spectrum of risk or respond accordingly. As a result, opportunities to improve the care, survival, and development of children in resource-poor settings are overlooked. Children at high risk of mortality are underidentified and commonly treated using guidelines that do not differentiate care according to the magnitude or drivers of those risks. Children at low risk of mortality are often provided with more intensive care than needed, disproportionately using limited health-care resources with minimal or no benefits. Declines in newborn, infant, and child mortality rates globally are slowing, and further reductions are likely to be incrementally more difficult to achieve once simple, high impact interventions have been universally implemented. Currently, 63 countries have rates of neonatal mortality that are off track to meet the Sustainable Development Goal 2030 target of 12 deaths per 1000 livebirths or less, and 54 countries have rates of mortality in children younger than 5 years that are off track to meet the target of 25 deaths per 1000 livebirths or less. If these targets are to be met, a change of approach is needed to address infant and child mortality and for health-care systems to more efficiently address residual mortality.

RESUMEN

Background: Antimicrobial resistance (AMR) is a global threat to infectious disease control, particularly among recently hospitalized children. We sought to determine the prevalence and mitigating factors of resistance in enteric Escherichia coli among children discharged from health facilities in western Kenya. Methods: Between June 2016 and November 2019, children aged 1 to 59 months were enrolled at the point of discharge from the hospital. E coli was isolated by microbiological culture from rectal swabs at baseline. ß-Lactamases and macrolide resistance-conferring genes were detected by polymerase chain reaction. A modified Poisson regression model was used to assess the predictors mph(A) and CTX-M-type extended-spectrum ß-lactamase (ESBL). Results: Of the 238 children whose E coli isolates were tested, 91 (38.2%) and 109 (45.8%) had detectable CTX-M-type ESBL and mph(A) genes, respectively. Antibiotic treatment during hospitalization (adjusted prevalence ratio [aPR], 2.47; 95% CI, 1.12-5.43; P = .025), length of hospitalization (aPR, 1.42; 95% CI, 1.00-2.01; P = .052), and the practice of open defecation (aPR, 2.47; 95% CI, 1.40-4.36; P = .002) were independent predictors for CTX-M-type ESBL and mph(A) genes. Pneumococcal vaccination was associated with a 43% lower likelihood of CTX-M-type ESBL (aPR, 0.57; 95% CI, .38-.85; P = .005), while measles vaccination was associated with a 32% lower likelihood of mph(A) genes (aPR, 0.68; 95% CI, .49-.93; P = .017) in E coli isolates. Conclusions: Among children discharged from the hospital, history of vaccination, shorter hospital stay, lack of in-hospital antibiotic exposure, and improved sanitation were associated with a lower likelihood of AMR genes. To mitigate the continued spread of AMR, AMR control programs should consider strategies beyond antimicrobial stewardship, including improvements in sanitation, increased vaccine coverage, and the development of novel vaccines.

RESUMEN

INTRODUCTION: Cervical cancer screening (CCS) among East African immigrants (EAI) in the USA is under explored. This study aimed to investigate adherence to CCS and its correlates among EAI. METHODS: We identified 1664 EAI women (25-65 years) with ≥ 1 primary care clinic visit(s) between 2017 and 2018, using University of Washington (UW) Medicine electronic health record data. CCS adherence was defined as Pap testing within 3 years or human papillomavirus/Pap co-testing within 5 years. We used Poisson regression with robust standard errors to cross-sectionally estimate associations with correlates of adherence. Twelve-month screening uptake was also evaluated among overdue women. RESULTS: CCS adherence was 63%. Factors associated with higher adherence included older age (adjusted prevalence ratios [APRs]:1.47:95%CI:1.14-1.90, 1.38:95%CI:1.05-1.80, respectively, for ages 30-39 and 40-49 vs 25-29 years), longer duration of care at UW Medicine (APR:1.22:95%CI:1.03-1.45, comparing > 10 vs < 5 years), higher visit frequency (APR:1.23:95%CI:1.04-1.44, 1.46:95%CI:1.24-1.72, respectively, for 3-5 and ≥ 6 vs 1-2 visits), index visit in an obstetrics-gynecology clinic (APR:1.26:95%CI:1.03-1.55, vs family practice), having an assigned primary care provider (APR:1.35: 95%CI:1.02-1.79), breast cancer screening adherence (APR:1.66: 95%CI:1.27-2.17), and colorectal cancer screening adherence (APR:1.59:95%CI:1.24-2.03). Low BMI was associated with lower adherence (APR:0.50:95%CI:0.26-0.96, comparing < 18.5 kg/m2 vs 18.5-24.9 kg/m2). Among 608 (37%) overdue women, 9% were screened in the subsequent 12 months. Having commercial health insurance vs Medicare/Medicaid was associated with higher uptake (adjusted risk ratio:2.44:95%CI:1.15-5.18). CONCLUSION: CCS adherence among EAI was lower than the national average of 80%. Interventions focused on increasing healthcare access/utilization or leveraging healthcare encounters to address barriers could increase CCS in EAIs.

RESUMEN

RATIONALE: Since the first documentation of skin changes in malnutrition in the early 18th century, various hair and skin changes have been reported in severely malnourished children globally. We aimed to describe the frequency and types of skin conditions in children admitted with acute illness to Queen Elizabeth Central Hospital, Blantyre, Malawi across a spectrum of nutritional status and validate an existing skin assessment tool. METHODS: Children between 1 week and 23 months of age with acute illness were enrolled and stratified by anthropometry. Standardised photographs were taken, and three dermatologists assessed skin changes and scored each child according to the SCORDoK tool. RESULTS: Among 103 children, median age of 12 months, 31 (30%) had severe wasting, 11 (11%) kwashiorkor (nutritional oedema), 20 (19%) had moderate wasting, 41 (40%) had no nutritional wasting and 18 (17%) a positive HIV antibody test. Six (5.8%) of the included patients died. 51 (50%) of children presented with at least one skin change. Pigmentary changes were the most common, observed in 35 (34%), with hair loss and bullae, erosions and desquamation the second most prevalent skin condition. Common diagnoses were congenital dermal melanocytosis, diaper dermatitis, eczema and postinflammatory hyperpigmentation. Severe skin changes like flaky paint dermatosis were rarely identified. Inter-rater variability calculations showed only fair agreement (overall Fleiss' kappa 0.25) while intrarater variability had a fair-moderate agreement (Cohen's kappa score of 0.47-0.58). DISCUSSION: Skin changes in hospitalised children with an acute illness and stratified according to nutritional status were not as prevalent as historically reported. Dermatological assessment by means of the SKORDoK tool using photographs is less reliable than expected.

RESUMEN

OBJECTIVE: The objective was to assess the association between nutritional and clinical characteristics and quantitative PCR (qPCR)-diagnosis of bacterial diarrhoea in a multicentre cohort of children under 2 years of age with moderate to severe diarrhoea (MSD). DESIGN: A secondary cross-sectional analysis of baseline data collected from the AntiBiotics for Children with Diarrhoea trial (NCT03130114). PATIENTS: Children with MSD (defined as >3 loose stools within 24 hours and presenting with at least one of the following: some/severe dehydration, moderate acute malnutrition (MAM) or severe stunting) enrolled in the ABCD trial and collected stool sample. STUDY PERIOD: June 2017-July 2019. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Likely bacterial aetiology of diarrhoea. Secondary outcomes included specific diarrhoea aetiology. RESULTS: A total of 6692 children with MSD had qPCR results available and 28% had likely bacterial diarrhoea aetiology. Compared with children with severe stunting, children with MAM (adjusted OR (aOR) (95% CI) 1.56 (1.18 to 2.08)), some/severe dehydration (aOR (95% CI) 1.66 (1.25 to 2.22)) or both (aOR (95% CI) 2.21 (1.61 to 3.06)), had higher odds of having likely bacterial diarrhoea aetiology. Similar trends were noted for stable toxin-enterotoxigenic Escherichia coli aetiology. Clinical correlates including fever and prolonged duration of diarrhoea were not associated with likely bacterial aetiology; children with more than six stools in the previous 24 hours had higher odds of likely bacterial diarrhoea (aOR (95% CI) 1.20 (1.05 to 1.36)) compared with those with fewer stools. CONCLUSION: The presence of MAM, dehydration or high stool frequency may be helpful in identifying children with MSD who might benefit from antibiotics.

RESUMEN

BACKGROUND: The emergence and spread of ß-lactamase-producing Klebsiella spp. has been associated with a substantial healthcare burden resulting in therapeutic failures. We sought to describe the proportion of phenotypic resistance to commonly used antibiotics, characterize ß-lactamase genes among isolates with antimicrobial resistance (AMR), and assess the correlates of phenotypic AMR in Klebsiella spp. isolated from stool or rectal swab samples collected from children being discharged from hospital. METHODS: We conducted a cross-sectional study involving 245 children aged 1-59 months who were being discharged from hospitals in western Kenya between June 2016 and November 2019. Whole stool or rectal swab samples were collected and Klebsiella spp. isolated by standard microbiological culture. ß-lactamase genes were detected by PCR whilst phenotypic antimicrobial susceptibility was determined using the disc diffusion technique following standard microbiology protocols. Descriptive analyses were used to characterize phenotypic AMR and carriage of ß-lactamase-producing genes. The modified Poisson regression models were used to assess correlates of phenotypic beta-lactam resistance. RESULTS: The prevalence of ß-lactamase carriage among Klebsiella spp. isolates at hospital discharge was 62.9% (154/245). Antibiotic use during hospitalization (adjusted prevalence ratio [aPR] = 4.51; 95%CI: 1.79-11.4, p < 0.001), longer duration of hospitalization (aPR = 1.42; 95%CI: 1.14-1.77, p < 0.002), and access to treated water (aPR = 1.38; 95%CI: 1.12-1.71, p < 0.003), were significant predictors of phenotypically determined ß-lactamase. All the 154 ß-lactamase-producing Klebsiella spp. isolates had at least one genetic marker of ß-lactam/third-generation cephalosporin resistance. The most prevalent genes were blaCTX-M 142/154 (92.2%,) and blaSHV 142/154 (92.2%,) followed by blaTEM 88/154 (57.1%,) and blaOXA 48/154 (31.2%,) respectively. CONCLUSION: Carriage of ß-lactamase producing Klebsiella spp. in stool is common among children discharged from hospital in western Kenya and is associated with longer duration of hospitalization, antibiotic use, and access to treated water. The findings emphasize the need for continued monitoring of antimicrobial susceptibility patterns to inform the development and implementation of appropriate treatment guidelines. In addition, we recommend measures beyond antimicrobial stewardship and infection control within hospitals, improved sanitation, and access to safe drinking water to mitigate the spread of ß-lactamase-producing Klebsiella pathogens in these and similar settings.

RESUMEN

Less than two-thirds of US adolescents are up-to-date with HPV vaccination. While mothers engaged in preventive care are more likely to seek preventive care for their children, current studies on associations between maternal cervical cancer screening (CCS) and adolescent HPV vaccination are needed. We assessed associations between maternal preventive service utilization and adolescent HPV vaccination using electronic health record data from a healthcare system in Washington State. We included adolescents (11-17 years) and their mothers with ≥ 1 primary care visit between 2018 and 2020. Outcomes were HPV vaccine initiation and completion. The primary exposure was maternal adherence to guideline-recommended CCS. Secondary exposures were maternal breast cancer screening adherence (for mothers ≥ 52 years) and ≥ 1 wellness visit ≤ 2 years. We used Generalized Estimating Equations to estimate prevalence ratios, and explore effect modification by adolescent sex, adolescent provider characteristics, and maternal language interpreter use. Of 4121 adolescents, 66% had a CCS-adherent mother, 82% initiated HPV vaccination, and 49% completed the series. CCS adherence was associated with higher initiation (adjusted prevalence ratio (APR):1.10, 95%CI:1.06-1.13) and completion (APR:1.16, 95%CI:1.08-1.23). Associations were stronger for male vs. female adolescents, adolescents who had a primary care provider in family practice vs. pediatrics, and adolescents who had the same primary care provider as their mother vs. not. Recent maternal wellness visit was also associated with higher initiation (APR:1.04, 95%CI:1.01-1.07) and completion (APR:1.12, 95%CI:1.05-1.20). Results suggest that delivering healthcare through a family-centered approach and engaging mothers in broad preventive care could increase adolescent HPV vaccination coverage.

RESUMEN

This study was undertaken to understand the perspective of adolescents in endemic communities of India regarding soil-transmitted helminth (STH) infections and community-wide mass drug administration (cMDA). A multicountry community-based cluster-randomized trial, the Deworm3 trial, tested the feasibility of interrupting STH transmission with cMDA, where all individuals aged 1-99 are treated empirically with albendazole. Using a guideline based on the Consolidated Framework for Implementation Research, eight focus group discussions were conducted among 57 adolescents from the trial site in India and analyzed on ATLAS.ti 8.0 software using an a priori thematic codebook. Adolescents believed that adults could be a source of STH infection because they were not routinely dewormed like the children through the national deworming program. Perceived benefits of cMDA for all were better health and increased work efficiency. Perceived barriers to adults' participation in cMDA was their mistrust about the program, fear of side effects, perceived low risk of infection, and absence during drug distribution. To encourage adult participation in cMDAs, adolescents suggested community outreach activities, engaging village influencers and health workers, and tailoring drug distribution to when adults would be available. Adolescents were confident in their ability to be change agents within their households for treatment compliance. Adolescents provided insights into potential barriers and solutions to improve adult participation in cMDA, identified best practices of cMDA delivery, and suggested that they have unique roles as change agents to increase their household participation in cMDA.

RESUMEN

Background: Growth faltering is well-recognized during acute childhood illness and growth acceleration during convalescence, with or without nutritional therapy, may occur. However, there are limited recent data on growth after hospitalization in low- and middle-income countries. Methods: We evaluated growth following hospitalization among children aged 2-23 months in sub-Saharan Africa and South Asia. Between November 2016 and January 2019, children were recruited at hospital admission and classified as: not-wasted (NW), moderately-wasted (MW), severely-wasted (SW), or having nutritional oedema (NO). We describe earlier (discharge to 45-days) and later (45- to 180-days) changes in length-for-age [LAZ], weight-for-age [WAZ], mid-upper arm circumference [MUACZ], weight-for-length [WLZ] z-scores, and clinical, nutritional, and socioeconomic correlates. Findings: We included 2472 children who survived to 180-days post-discharge: NW, 960 (39%); MW, 572 (23%); SW, 682 (28%); and NO, 258 (10%). During 180-days, LAZ decreased in NW (-0.27 [-0.36, -0.19]) and MW (-0.23 [-0.34, -0.11]). However, all groups increased WAZ (NW, 0.21 [95% CI: 0.11, 0.32]; MW, 0.57 [0.44, 0.71]; SW, 1.0 [0.88, 1.1] and NO, 1.3 [1.1, 1.5]) with greatest gains in the first 45-days. Of children underweight (<-2 WAZ) at discharge, 66% remained underweight at 180-days. Lower WAZ post-discharge was associated with age-inappropriate nutrition, adverse caregiver characteristics, small size at birth, severe or moderate anaemia, and chronic conditions, while lower LAZ was additionally associated with household-level exposures but not with chronic medical conditions. Interpretation: Underweight and poor linear growth mostly persisted after an acute illness. Beyond short-term nutritional supplementation, improving linear growth post-discharge may require broader individual and family support.

RESUMEN

OBJECTIVES: This study evaluated the prevalence and correlates of guideline non-adherence for common childhood illnesses in low-resource settings. DESIGN AND SETTING: We used secondary cross-sectional data from eight healthcare facilities in six Asian and African countries. PARTICIPANTS: A total of 2796 children aged 2-23 months hospitalised between November 2016 and January 2019 with pneumonia, diarrhoea or severe malnutrition (SM) and without HIV infection were included in this study. PRIMARY OUTCOME MEASURES: We identified children treated with full, partial or non-adherent initial inpatient care according to site-specific standard-of-care guidelines for pneumonia, diarrhoea and SM within the first 24 hours of admission. Correlates of guideline non-adherence were identified using generalised estimating equations. RESULTS: Fully adherent care was delivered to 32% of children admitted with diarrhoea, 34% of children with pneumonia and 28% of children with SM when a strict definition of adherence was applied. Non-adherence to recommendations was most common for oxygen and antibiotics for pneumonia; fluid, zinc and antibiotics for diarrhoea; and vitamin A and zinc for SM. Non-adherence varied by site. Pneumonia guideline non-adherence was more likely among patients with severe disease (OR 1.82; 95% CI 1.38, 2.34) compared with non-severe disease. Diarrhoea guideline non-adherence was more likely among lower asset quintile groups (OR 1.16; 95% CI 1.01, 1.35), older children (OR 1.10; 95% CI 1.06, 1.13) and children presenting with wasting (OR 6.44; 95% CI 4.33, 9.57) compared with those with higher assets, younger age and not wasted. CONCLUSIONS: Non-adherence to paediatric guidelines was common and associated with older age, disease severity, and comorbidities, and lower household economic status. These findings highlight opportunities to improve guidelines by adding clarity to specific recommendations.

RESUMEN

BACKGROUND: Soil-transmitted helminth infections (STH) are associated with substantial morbidity in low-and-middle-income countries, accounting for 2.7 million disability-adjusted life years annually. Current World Health Organization guidelines recommend controlling STH-associated morbidity through periodic deworming of at-risk populations, including children and women of reproductive age (15-49 years). However, there is increasing interest in community-wide mass drug administration (cMDA) which includes deworming adults who serve as infection reservoirs as a method to improve coverage and possibly to interrupt STH transmission. We investigated determinants of cMDA coverage by comparing high-coverage clusters (HCCs) and low-coverage clusters (LCCs) receiving STH cMDA in three countries. METHODS: A convergent mixed-methods design was used to analyze data from HCCs and LCCs in DeWorm3 trial sites in Benin, India, and Malawi following three rounds of cMDA. Qualitative data were collected via 48 community-level focus group discussions. Quantitative data were collected via routine activities nested within the DeWorm3 trial, including annual censuses and coverage surveys. The Consolidated Framework for Implementation Research (CFIR) guided coding, theme development and a rating process to determine the influence of each CFIR construct on cMDA coverage. RESULTS: Of 23 CFIR constructs evaluated, we identified 11 constructs that differentiated between HCCs and LCCs, indicating they are potential drivers of coverage. Determinants differentiating HCC and LCC include participant experiences with previous community-wide programs, communities' perceptions of directly observed therapy (DOT), perceptions about the treatment uptake behaviors of neighbors, and women's agency to make household-level treatment decisions. CONCLUSION: The convergent mixed-methods study identified barriers and facilitators that may be useful to NTD programs to improve cMDA implementation for STH, increase treatment coverage, and contribute to the successful control or elimination of STH. TRIAL REGISTRATION: The parent trial was registered at clinicaltrials.gov (NCT03014167).

RESUMEN

There is scarce data on energy expenditure in ill children with different degrees of malnutrition. This study aimed to determine resting energy expenditure (REE) trajectories in hospitalized malnourished children during and after hospitalization. We followed a cohort of children in Bangladesh and Malawi (2-23 months) with: no wasting (NW); moderate wasting (MW), severe wasting (SW), or edematous malnutrition (EM). REE was measured by indirect calorimetry at admission, discharge, 14-and-45-days post-discharge. 125 children (NW, n = 23; MW, n = 29; SW, n = 51; EM, n = 22), median age 9 (IQR 6, 14) months, provided 401 REE measurements. At admission, the REE of children with NW and MW was 67 (95% CI [58, 75]) and 70 (95% CI [63, 76]) kcal/kg/day, respectively, while REE in children with SW was higher, 79 kcal/kg/day (95% CI [74, 84], p = 0.018), than NW. REE in these groups was stable over time. In children with EM, REE increased from admission to discharge (65 kcal/kg/day, 95% CI [56, 73]) to 79 (95% CI [72, 86], p = 0.0014) and was stable hereafter. Predictive equations underestimated REE in 92% of participants at all time points. Recommended feeding targets during the acute phase of illness in severely malnourished children exceeded REE. Acutely ill malnourished children are at risk of being overfed when implementing current international guidelines.
