Neurological Impact of Slower Rewarming during Bypass Surgery in Infants.

BACKGROUND: Hypothermia is a neuroprotective strategy during cardiopulmonary bypass. Rewarming entailing a rapid rise in cerebral metabolism might lead to secondary neurological sequelae. In this pilot study, we aimed to validate the hypothesis that a slower rewarming rate would lower the risk of cerebral hypoxia and seizures in infants. METHODS: This is a prospective, clinical, single-center study. Infants undergoing cardiac surgery in hypothermia were rewarmed either according to the standard (+1°C in < 5 minutes) or a slow (+1°C in > 5-8 minutes) rewarming strategy. We monitored electrocortical activity via amplitude-integrated electroencephalography (aEEG) and cerebral oxygenation by near-infrared spectroscopy during and after surgery. RESULTS: Fifteen children in the standard rewarming group (age: 13 days [5-251]) were cooled down to 26.6°C (17.2-29.8) and compared with 17 children in the slow-rewarming group (age: 9 days [4-365]) with a minimal temperature of 25.7°C (20.1-31.4). All neonates in both groups (n = 19) exhibited suppressed patterns compared with 28% of the infants > 28 days (p < 0.05). During rewarming, only 26% of the children in the slow-rewarming group revealed suppressed aEEG traces (vs. 41%; p = 0.28). Cerebral oxygenation increased by a median of 3.5% in the slow-rewarming group versus 1.5% in the standard group (p = 0.9). Our slow-rewarming group revealed no aEEG evidence of any postoperative seizures (0 vs. 20%). CONCLUSION: These results might indicate that a slower rewarming rate after hypothermia causes less suppression of electrocortical activity and higher cerebral oxygenation during rewarming, which may imply a reduced risk of postoperative seizures.

Impact of Suaahara, an integrated nutrition programme, on maternal and child nutrition at scale in Nepal.

Suaahara was an innovative, complex, multi-sectoral, large-scale, nutrition programme in Nepal to increase exposure to nutrition-related information and services, improve nutrition-related knowledge and practices among pregnant women and mothers of infants and young children, and improve their nutrition. This study evaluated the effectiveness of Suaahara to improve nutrition and nutrition-related practices by comparing changes over 10 years between intervention and comparison districts. The samples of households at baseline in 2012 and endline in 2022 were 2040 and 2480, respectively, from 120 old wards. The impact was estimated using intent-to-treat regression models in which survey year, arm and their interaction were fixed effects, accounting for district clustering, with the interaction estimating differences between arms in changes over time. The intervention, relative to comparison, reduced maternal underweight by 8.43 percentage points (p < 0.001), consistent with improved maternal and fetal condition that was manifested as the greater length of 0.761 z-scores (p = 0.004) of infants 0-5.9 months. Complementary feeding practices with children between 6 and 23.9 months of age improved more in the intervention than comparison districts: child dietary diversity by 0.294 food groups (p = 0.072) and minimum dietary diversity by 9.51 percentage points (p = 0.028), feeding sick child more (p = 0.002) and administering oral rehydration solution and zinc for diarrhoea (p = 0.057) by about 17 percentage points each, and minimum meal frequency (p = 0.004) and minimum acceptable diet (p = 0.022) by about 15 percentage points each. Substantial impacts were demonstrated despite political restructuring, earthquakes, and other major challenges that Nepal and Suaahara faced and limitations in statistical power because of the reduced number of districts that then could be included in the study.

Engaging men in maternal, infant and young child nutrition in rural Tanzania: Outcomes from a cluster randomized control trial and qualitative study.

There is growing recognition that engaging men in maternal, infant and young child nutrition (MIYCN) interventions can benefit child health and disrupt harmful gender norms. We conducted a cluster-randomized controlled trial in Tanzania, which engaged men and women in behaviour change via mobile messaging (short message service [SMS]) and traditional interpersonal communication (IPC), separately and in combination. Here, we evaluate intervention effects on individual-level men's MIYCN knowledge and discuss barriers to male engagement. Eligible clusters were dispensary catchment areas with >3000 residents. Forty clusters were stratified by population size and randomly allocated to the four study arms, with 10 clusters per arm. Data on knowledge and intervention exposure were collected from 1394 men through baseline and endline surveys (March-April 2018 and July-September 2019). A process evaluation conducted partway through the 15-18-month intervention period included focus group discussions and interviews. Data were analysed for key trends and themes using Stata and ATLAS.ti software. Male participants in the short message service + interpersonal communication (SMS + IPC) group reported higher exposure to IPC discussions than IPC-only men (43.8% and 21.9%, respectively). Knowledge scores increased significantly across all three intervention groups, with the greatest impact in the SMS + IPC group. Qualitative findings indicated that the main barriers to male participation were a lack of interest in health/nutrition and perceptions that these topics were a woman's responsibility. Other challenges included meeting logistics, prioritizing income-earning activities and insufficient efforts to engage men. The use of a combined approach fusing IPC with SMS is promising, yet countering gender norms and encouraging stronger male engagement may require additional strategies.

Between the city and the farm: food environments in artisanal mining communities in Upper Guinea.

OBJECTIVE: Artisanal and small-scale mining (ASM) is a widespread livelihood in low- and middle-income countries; however, many in ASM communities face high levels of poverty and malnutrition. The food environments in ASM communities have non-agricultural rural characteristics that differ from those in urban and agricultural rural areas examined in much existing food environment literature. DESIGN: We examine these complex external and personal food environments in ASM communities via a study using qualitative and quantitative methods. Market surveys and a cross-sectional household survey, plus qualitative mining site non-participant observations and in-depth structured interviews, were conducted in three waves. SETTING: Eighteen study sites in ASM communities in northern Guinea. PARTICIPANTS: Surveys covered mothers in mining households with young children (n 613); in-depth interviews engaged caregivers of young children (n 45), food vendors (n 40) and young single miners (n 15); observations focused on mothers of young children (n 25). RESULTS: The external food environment in these ASM communities combines widespread availability of commercially processed and staple-heavy foods with lower availability and higher prices for more nutritious, non-staple foods. Within the personal food environment, miners are constrained in their food choices by considerable variability in daily cash income and limited time for acquisition and preparation. CONCLUSIONS: We demonstrate that ASM communities have characteristics of both urban and rural populations and argue for greater nuance and appreciation of complexity in food environment research and resultant policy and programming.

Assessing the challenges to women's access and implementation of text messages for nutrition behaviour change in rural Tanzania.

OBJECTIVE: This process evaluation aimed to understand factors affecting the implementation of a government-sponsored short message service (SMS) programme for delivering nutrition information to rural populations, including message access, acceptability and putting messages into action. DESIGN: The study was nested within a larger randomised controlled trial. Cross-sectional data collection included structured surveys and in-depth interviews. Data were analysed for key trends and themes using Stata and ATLAS.ti software. SETTING: The study took place in Tanzania's Mtwara region. PARTICIPANTS: Surveys were conducted with 205 women and 93 men already enrolled in the randomised controlled trial. A sub-set of 30 women and 14 men participated in the in-depth interviews. RESULTS: Among women relying on a spouse's phone, sharing arrangements impeded regular SMS access; men were commonly away from home, forgot to share SMS or did not share them in women's preferred way. Phone-owning women faced challenges related to charging their phones and defective handsets. Once SMS were delivered, most participants viewed them as trustworthy and comprehensible. However, economic conditions limited the feasibility of applying certain recommendations, such as feeding meat to toddlers. A sub-set of participants concurrently enrolled in an interpersonal counselling (IPC) intervention indicated that the SMS provided reminders of lessons learned during the IPC; yet, the SMS did not help participants contextualise information and overcome the challenges of putting that information into practice. CONCLUSIONS: The challenges to accessing and implementing SMS services highlighted here suggest that such platforms may work well as one component of a comprehensive nutrition intervention, yet not as an isolated effort.

Letter to the Editor of the Journal of Artificial Organs: The flaws in the detail of describing methods, comparing patient cohorts and interpreting results.

We read with great interest the article written by Murphy et al. (J Artif Organs 22:286-293, 2019). We acknowledge the authors contribution. However, the results presented may be difficult to interpret due to several missing information and therefore may not support the conclusions. Therefore, the results of this publication should be viewed very critically.

Impact Evaluation of a Comprehensive Nutrition Program for Reducing Stunting in Children Aged 6-23 Months in Rural Malawi.

BACKGROUND: The prevalence of stunting in central rural Malawi is ∼50%, which prompted a multipronged nutrition program in 1 district from 2014 to 2016. The program distributed a daily, fortified, small-quantity lipid-based nutritional supplement, providing 110 kcal and 2.6 g of protein to children aged 6-23 mo, and behavior change messages around optimal infant and young child feeding (IYCF) and water, sanitation, and hygiene. OBJECTIVES: Our objective was to perform an impact evaluation of the program using a neighboring district as comparison. METHODS: Using a quasi-experimental study design, with cross-sectional baseline (January-March, 2014; n = 2404) and endline (January-March, 2017; n = 2453) surveys, we evaluated the program's impact using a neighboring district as comparison. Impact on stunting was estimated using propensity score weighted difference-in-differences regression analyses to account for baseline differences between districts. RESULTS: No differences in mean length-for-age z-score or prevalence of stunting were found at endline. However, mean weight, weight-for-length z-score, and mid-upper arm circumference were higher at endline by 150 g, 0.22, and 0.19 cm, respectively, in the program compared with the comparison district (all P < 0.05). Weekly reports of high fever and malaria were also lower by 6.4 and 4.7 percentage points, respectively, in the program compared with the comparison district (both P < 0.05). There was no impact on anemia. Children's dietary diversity score improved by 0.17, and caregivers' infant and young child feeding and hand-washing practices improved by 8-11% in the program compared with the comparison district (all P < 0.05). CONCLUSIONS: An impact evaluation of a comprehensive nutrition program in rural Malawi demonstrated benefit for child ponderal growth and health, improved maternal IYCF and hand-washing practices, but a reduction in stunting prevalence was not observed.

Maternal nutritional status mediates the linkage between household food insecurity and mid-infancy size in rural Bangladesh.

Household food insecurity (HFI) is a major concern in South Asia. The pathways by which HFI may reduce child growth remain inadequately understood. In a cohort study of 12 693 maternal-infant dyads in rural Bangladesh, we examined association and likely explanatory pathways linking HFI, assessed using a validated nine-item perception-based index, to infant size at 6 months. Mothers were assessed early in pregnancy for anthropometric status, dietary diversity and socio-economic status. Infants were assessed for weight, length, and arm, chest and head circumferences and breast and complementary feeding status at birth and 6 months of age. Extent of HFI shared a negative, dose-response association with all measures of infant size at 6 months and odds of wasting and stunting; 57-89 % of variances in the unadjusted models were explained by prenatal factors (maternal nutritional status and dietary diversity), and birth size adjusted for gestational age. Postnatal infant breast and complementary feeding and morbidity exposures explained the remaining fraction of the significant association between HFI and differences in infant arm and chest circumferences and odds of underweight. Contextual (i.e. socio-economic) factors finally brought remaining non-significant fractions of the food insecurity-related mid-infancy growth deficit to practically zero. Improving food security prior to pregnancy and during gestation would likely improve infant growth the most in rural Bangladesh.

Thinness and fecundability: Time to pregnancy after adolescent marriage in rural Bangladesh.

Undernutrition may affect fecundability, but few studies have quantified this relationship. In rural Bangladesh, where newlywed couples face strong pressures to become pregnant, we assessed fecundability, estimated by time to pregnancy (TTP), and its association with preconceptional thinness among nulligravid, newlywed female adolescents. During 2001-2002, 5,516 newlywed women aged 12-19 years participated in a home-based, 5-weekly surveillance system for 5-6 years to enrol pregnant women into an antenatal vitamin A or ß-carotene supplementation trial. Thinness was defined as a left mid-upper arm circumference (MUAC) ≤21.5 versus >21.5 cm. At each visit, staff obtained a monthly history of menstruation. Report of amenorrhea prompted a human chorionic gonadotropin urine test to confirm pregnancy. We derived hazard ratios (with 95% confidence intervals [CI]) for pregnancy and Kaplan-Meier curves for TTP. Ages of women at marriage and pregnancy detection (mean ± standard deviation) were 15.3 ± 1.9 and 17.0 ± 1.9 years, respectively. A total of 82.7% of thinner and 87.3% of better nourished women became pregnant. The unadjusted and multivariable relative hazard of ever becoming pregnant was 0.84 (95% CI [0.78, 0.89]) and 0.86 (95% CI [0.81, 0.92]), respectively, and TTP was 12 weeks longer (median [95% CI]: 63 [58-68] vs. 51 [49-54]) in women whose MUAC was ≤21.5 versus >21.5 cm. In rural Bangladesh, thin adolescent newlywed girls have a lower probability of becoming pregnant and experience a longer time to pregnancy.

Antenatal Multiple Micronutrient Supplementation Compared to Iron-Folic Acid Affects Micronutrient Status but Does Not Eliminate Deficiencies in a Randomized Controlled Trial Among Pregnant Women of Rural Bangladesh.

BACKGROUND: Antenatal multiple micronutrient (MM) supplementation improves birth outcomes relative to iron-folic acid (IFA) in developing countries, but limited data exist on its impact on pregnancy micronutrient status. OBJECTIVE: We assessed the efficacy of a daily MM (15 nutrients) compared with IFA supplement, each providing approximately 1 RDA of nutrients and given beginning at pregnancy ascertainment, on late pregnancy micronutrient status of women in rural Bangladesh. Secondarily, we explored other contributors to pregnancy micronutrient status. METHODS: Within a double-masked trial (JiVitA-3) among 44,500 pregnant women, micronutrient status indicators were assessed in n = 1526 women, allocated by cluster to receive daily MM (n = 749) or IFA (n = 777), at 10 wk (baseline: before supplementation) and 32 wk (during supplementation) gestation. Efficacy of MM supplementation on micronutrient status indicators at 32 wk was assessed, controlling for baseline status and other covariates (e.g., inflammation and season), in regression models. RESULTS: Baseline status was comparable by intervention. Prevalence of deficiency among all participants was as follows: anemia, 20.6%; iron by ferritin, 4.0%; iron by transferrin receptor, 4.7%; folate, 2.5%; vitamin B-12, 35.4%; vitamin A, 6.7%; vitamin E, 57.7%; vitamin D, 64.0%; zinc, 13.4%; and iodine, 2.6%. At 32 wk gestation, vitamin B-12, A, and D and zinc status indicators were 3.7-13.7% higher, and ferritin, γ-tocopherol, and thyroglobulin indicators were 8.7-16.6% lower, for the MM group compared with the IFA group, with a 15-38% lower prevalence of deficiencies of vitamins B-12, A, and D and zinc (all P < 0.05). However, indicators typically suggested worsening status during pregnancy, even with supplementation, and baseline status or other covariates were more strongly associated with late pregnancy indicators than was MM supplementation. CONCLUSIONS: Rural Bangladeshi women commonly entered pregnancy deficient in micronutrients other than iron and folic acid. Supplementation with MM improved micronutrient status, although deficiencies persisted. Preconception supplementation or higher nutrient doses may be warranted to support nutritional demands of pregnancy in undernourished populations. This trial was registered at clinicaltrials.gov as NCT00860470.

Household food insecurity is associated with low dietary diversity among pregnant and lactating women in rural Malawi.

OBJECTIVE: To examine the association between household food insecurity and dietary diversity in the past 24h (dietary diversity score (DDS, range: 0-9); minimum dietary diversity (MDD, consumption of three or more food groups); consumption of nine separate food groups) among pregnant and lactating women in rural Malawi. DESIGN: Cross-sectional study. SETTING: Two rural districts in Central Malawi. SUBJECTS: Pregnant (n 589) and lactating (n 641) women. RESULTS: Of surveyed pregnant and lactating women, 66·7 and 68·6 %, respectively, experienced moderate or severe food insecurity and only 32·4 and 28·1 %, respectively, met MDD. Compared with food-secure pregnant women, those who reported severe food insecurity had a 0·36 lower DDS (P<0·05) and more than threefold higher risk (OR; 95 % CI) of not consuming meat/fish (3·19; CI 1·68, 6·03). The risk of not consuming eggs (3·77; 1·04, 13·7) was higher among moderately food-insecure pregnant women. Compared with food-secure lactating women, those who reported mild, moderate and severe food insecurity showed a 0·36, 0·44 and 0·62 lower DDS, respectively (all P<0·05). The risk of not achieving MDD was higher among moderately (1·95; 1·06, 3·59) and severely (2·82; 1·53, 5·22) food-insecure lactating women. The risk of not consuming meat/fish and eggs increased in a dose-response manner among lactating women experiencing mild (1·75; 1·01, 3·03 and 2·81; 1·09, 7·25), moderate (2·66; 1·47, 4·82 and 3·75; 1·40, 10·0) and severe (5·33; 2·63, 10·8 and 3·47; 1·19, 10·1) food insecurity. CONCLUSIONS: Addressing food insecurity during and after pregnancy needs to be considered when designing nutrition programmes aiming to increase dietary diversity in rural Malawi.

Unintended pregnancy is a risk factor for depressive symptoms among socio-economically disadvantaged women in rural Bangladesh.

BACKGROUND: Little is known about the relation between unwanted pregnancy and intention discordance and maternal mental health in low-income countries. The study aim was to evaluate maternal and paternal pregnancy intentions (and intention discordance) in relation to perinatal depressive symptoms among rural Bangladeshi women. METHODS: Data come from a population-based, community trial of married rural Bangladeshi women aged 13-44. We examined pregnancy intentions among couples and pregnancy-intention discordance, as reported by women at enrollment soon after pregnancy ascertainment, in relation to depressive symptoms in the third trimester of pregnancy (N = 14,629) and six months postpartum (N = 31,422). We calculated crude and adjusted risk ratios for prenatal and postnatal depressive symptoms by pregnancy intentions. RESULTS: In multivariable analyses, women with unwanted pregnancies were at higher risk of prenatal (Adj. RR = 1.60, 95% CI: 1.37-1.87) and postnatal depressive symptoms (Adj. RR = 1.32, 95% CI: 1.21-1.44) than women with wanted pregnancies. Women who perceived their husbands did not want the pregnancy also were at higher risk for prenatal (Adj. RR = 1.42, 95% CI: 1.22-1.65) and postnatal depressive symptoms (Adj. RR = 1.30, 95% CI: 1.19-1.41). Both parents not wanting the pregnancy was associated with prenatal and postnatal depressive symptoms (Adj. RR = 1.34, 95% CI: 1.19-1.52; Adj. RR = 1.13, 95% CI: 1.06-1.21, respectively), compared to when both parents wanted it. Adjusting for socio-demographic and pregnancy intention variables simultaneously, maternal intentions and pregnancy discordance were significantly related to prenatal depressive symptoms, and perception of paternal pregnancy unwantedness and couple pregnancy discordance, with postnatal depressive symptoms. CONCLUSIONS: Maternal, paternal and discordant couple pregnancy intentions, as perceived by rural Bangladeshi women, are important risk factors for perinatal maternal depressive symptoms.

Improving maternal, infant and young child nutrition in Nepal via peer mobilization.

OBJECTIVE: To evaluate the impact of a peer facilitator (PF) approach for improving mothers' knowledge and practices relating to maternal and child nutrition. DESIGN: A quasi-experimental design nested within a large-scale integrated nutrition programme, Suaahara, in Nepal. Suaahara interventions were implemented in all study sites, but peer facilitators were used in only half of the study sites. SETTING: Rural, disadvantaged villages in three districts of Nepal: Bhojpur, Bajhang and Rupandehi. SUBJECTS: Mothers of children aged 6-23·9 months (n 1890). RESULTS: Differences over time between comparison (C) and intervention (I) groups show that the PF approach had a significant positive impact on several indicators of mothers' knowledge and practices relating to maternal and child nutrition: (i) knowing that fruits and vegetables are good for children 6-23·9 months (C: -0·7, I: 10·6; P=0·03); (ii) child dietary diversity (C: 0·02, I: 0·04; P=0·02); (iii) child minimum dietary diversity (≥4 of 7 food groups; (C: 6·9, I: 16·0; P=0·02); (iv) maternal dietary diversity (C: 0·1, I: 0·4; P=0·01); and (v) maternal minimum dietary diversity (≥4 food groups; C: 3·6, I: 14·0; P=0·03). Additionally, exposure to a PF three or more times in the past 6 months was positively associated with a small improvement in maternal (ß=0·06, P=0·04) and child (ß=0·06, P=0·02) dietary diversity scores. Improvements were not observed in maternal health-seeking behaviours such as number of antenatal care visits. CONCLUSIONS: Peer mobilization is a potential approach for improving health- and nutrition-related knowledge and behaviours among women in hard-to-reach communities of Nepal.

Implementing and Assessing a Standardized Protocol for Weaning Children Successfully From Extracorporeal Life Support.

Extracorporeal life support (ECLS) weaning is a complex interdisciplinary process with no clear guidelines. To assess ventricular and pulmonary function as well as hemodynamics including end-organ recovery during ECLS weaning, we developed a standardized weaning protocol. We reviewed our experience 2 years later to assess its feasibility and efficacy. In 2015 we established an inter-professional, standardized, stepwise protocol for weaning from ECLS. If the patient did not require further surgery, weaning was conducted bedside in the intensive care unit (ICU). Most of the weaning procedures are guided via echocardiography. Data acquisition began at baseline level, followed by four-step course (each step lasting 10 min), entailing flow-reduction and ending 30 min after decannulation. Moreover, data from the preprotocol era are presented. Between May 2015 and 2017, 26 consecutive patients (18 male), median age 177 days (2 days-20 years) required ECLS with median support of 4 (2-11) days. Excluding eight not weanable patients, 21 standardized weaning procedures were protocolled in the remaining 18 children. Our generally successful protocol-guided weaning rate (with at least 24-h survival) was 89%, with a discharge home rate of 58%. Practical application of the novel standard protocol seems to facilitate ECLS weaning and to improve its success rate. The protocol can be administered as part of standard bedside ICU assessment.

Implementing small-scale poultry-for-nutrition projects: Successes and lessons learned.

This paper examines Helen Keller International's model for nutrition-sensitive poultry production using a programme implemented in four diverse African contexts-three rural and one urban. Consecutive cross-sectional surveys conducted every 5 months among ~15% of participating households show that despite project-provided training and inputs, there was only limited uptake of many "best practices." Few households constructed improved henhouses; vaccination rates varied and were highest when support was provided. Poultry mortality was high. Egg productivity remained average for village poultry systems, and egg consumption remained low (two to six eggs consumed per household per fortnight). However, children whose mothers were exposed to project messages on nutrition were more likely to eat eggs, and consumption was consistently higher among households with chickens. Women's involvement in chicken rearing was widespread, but their control over revenues from the sale of poultry products was limited. Key lessons learned from implementation were as follows: (a) strong behaviour change communication is needed to encourage egg consumption, (b) nutrition-sensitive village poultry programmes should often focus more on improved practices than improved breeds, (c) supporting women's chicken production is not a route to empowerment without complementary activities that directly support women's ownership and decision making. There is also a need for rigorous research on the role of village poultry in livelihoods, food systems, and consumption as well as the structure of poultry and egg markets in low-resource areas.

Individual, household, and community level risk factors of stunting in children younger than 5 years: Findings from a national surveillance system in Nepal.

Despite substantial reductions in recent years in Nepal, stunting prevalence in children younger than 5 years remains high and represents a leading public health concern. To identify factors contributing to the stunting burden, we report multilevel risk factors associated with stunting in 4,853 children aged 6-59 months in a nationally and agroecologically representative random sample from the first year of the Policy and Science for Health, Agriculture, and Nutrition Community Studies, a community-based observational, mixed-panel study. Mixed effects logistic regressions controlling for multilevel clustering in the study design were used to examine the association of individual-, household-, and community-level factors associated with stunting. Stunting prevalence was 38% in our sample. After adjustment for potential confounding variables, maternal factors, including maternal height and education, were generally the strongest individual-level risk factors for stunting, adjusted odds ratio (AOR) = 2.52, 95% CI [1.96, 3.25], short (<145 cm) versus not short mothers; AOR = 2.09, 95% CI [1.48, 2.96], uneducated mothers versus secondary school graduates. Among the household- and community-level factors, household expenditure and community infrastructure (presence of paved roads, markets, or hospitals) were strongly, inversely associated with increased stunting risk, AOR = 1.68, 95% CI [1.27, 2.24], lowest versus highest household expenditure quintile; AOR = 2.38, 95% CI [1.36, 4.14], less developed (lacking paved roads, markets, or hospitals) versus more developed communities. Although most factors associated with stunting are not rapidly modifiable, areas for future research and possible interventions emerged.

Determinants of successful vitamin A supplementation coverage among children aged 6-59 months in thirteen sub-Saharan African countries.

OBJECTIVE: Vitamin A supplementation (VAS) for children aged 6-59 months occurs regularly in most sub-Saharan African countries. The present study aimed to explore child, household and delivery platform factors associated with VAS coverage and identify barriers to compliance in thirteen African countries. DESIGN: We pooled data (n ~60 000) from forty-four household coverage surveys and used bivariate and multivariable regression analyses to assess the effects of supplementation strategy, rural v. urban residence, child sex, child age, caregiver education and campaign awareness on child VAS status. Setting/Subjects Primary caregivers of children aged 6-59 months in thirteen countries. RESULTS: Door-to-door distribution resulted in higher VAS coverage than fixed-site plus outreach approaches (91 v. 63 %) and was a significant predictor of supplementation in the adjusted model (OR=19·0; 95 % CI 17·2, 21·1; P<0·001). Having been informed about the campaign was the main predictor of VAS in the door-to-door (OR=6·8; 95 % CI 5·8, 7·9; P<0·001) and fixed-site plus outreach (OR=72·5; 95 % CI 66·6, 78·8; P<0·001) groups. CONCLUSIONS: Door-to-door provision of VAS may achieve higher coverage than fixed-site models in the African context. However, the phase-out of door-to-door polio immunization campaigns in most sub-Saharan African countries threatens the main distribution vehicle for VAS. Our findings suggest well-informed communities are key to attaining higher coverage using fixed-site delivery alternatives.

Risk of Depressive Symptoms Associated with Morbidity in Postpartum Women in Rural Bangladesh.

Objectives Depression following pregnancy is common, but its extent and association with maternal morbidity in the first 6 months postpartum have not been well described in low resource settings such as rural Bangladesh. Methods We used data from a population-based, community trial of approximately 39,000 married rural Bangladeshi women aged 13-44 between 2001 and 2007 to examine the relation between women's reported morbidity symptoms from childbirth to 3 months postpartum, and subsequent depressive symptoms assessed at 6 months postpartum. We calculated crude and adjusted risk ratios for depressive symptoms following women's reports of reproductive, urinary, neurologic, nutrition and other illness measures constructed based on symptomatic reporting. Results In models adjusted for sociodemographic factors and co-morbidities, all postpartum illnesses were associated with an increased relative risk [RR, with 95% confidence intervals (CI) excluding 1] of depressive symptoms by 6 months postpartum. These morbidities included uterine prolapse (RR 1.20, 95% CI 1.04-1.39), urinary tract infection (RR 1.24, 95% CI 1.11-1.38), stress related incontinence (SRI) (RR 1.49, 95% 1.33-1.67), simultaneous SRI and continuously dripping urine (RR 1.60-2.96), headache [RR 1.20 (95% CI 1.12-1.28)], convulsions (RR 1.67, 95%CI 1.36-2.06), night blindness (RR 1.33, 95% CI 1.19-1.49), anemia (RR 1.38, 95% CI 1.31-1.46), pneumonia (RR 1.24, 95% CI 1.12-1.37), gastroenteritis (RR 1.24, 95% CI 1.17-1.31) and hepatobiliary disease (RR 2.10, 96% CI 1.69-2.60). Conclusions for Practice Illnesses during the first three postpartum months were risk factors for depressive symptoms, with the strongest associations noted for convulsions and hepatobiliary disease. Symptoms of depression may be of particular concern among women suffering from physical illnesses. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT0019882.

Executive summary for the Micronutrient Powders Consultation: Lessons Learned for Operational Guidance.

Iron deficiency anaemia is estimated to be the leading cause of years lived with disability among children. Young children's diets are often inadequate in iron and other micronutrients, and provision of essential vitamin and minerals has long been recommended. With the limited programmatic success of iron drop/syrup interventions, interest in micronutrient powders (MNP) has increased. MNP are a mixture of vitamins and minerals, enclosed in single-dose sachets, which are stirred into a child's portion of food immediately before consumption. MNP are an efficacious intervention for reducing iron deficiency anaemia and filling important nutrient gaps in children 6-23 months of age. As of 2014, 50 countries have implemented MNP programmes including 9 at a national level. This paper provides an overview of a 3-paper series, based on findings from the "Micronutrient Powders Consultation: Lessons Learned for Operational Guidance" held by the USAID-funded Strengthening Partnerships, Results, and Innovations in Nutrition Globally (SPRING) Project. The objectives of the Consultation were to identify and summarize the most recent MNP programme experiences and lessons learned for operationalizing MNP for young children and prioritize an implementation research agenda. The Consultation was composed of 3 working groups that used the following methods: deliberations among 49 MNP programme implementers and experts, a review of published and grey literature, questionnaires, and key informant interviews, described in this overview. The following articles summarize findings in 3 broad programme areas: planning, implementation, and continual programme improvement. The papers also outline priorities for implementation research to inform improved operationalization of MNP.

Experiences and lessons learned for planning and supply of micronutrient powders interventions.

Realistic planning for a nutrition intervention is a critical component of implementation, yet effective approaches have been poorly documented. Under the auspices of "The Micronutrient Powders Consultation: Lessons Learned for Operational Guidance," 3 working groups were formed to summarize experiences and lessons across countries regarding micronutrient powders (MNP) interventions for young children. This paper focuses on programmatic experiences in the planning stages of an MNP intervention, encompassing assessment, enabling environment and adaptation, as well as considerations for supply. Methods included a review of published and grey literature, key informant interviews, and deliberations throughout the consultation process. We found that assessments helped justify adopting an MNP intervention, but these assessments were often limited by their narrow scope and inadequate data. Establishing coordinating bodies and integrating MNP into existing policies and programmes have helped foster an enabling environment and support programme stability. Formative research and pilots have been used to adapt MNP interventions to specific contexts, but they have been insufficient to inform scale-up. In terms of supply, most countries have opted to procure MNP through international suppliers, but this still requires understanding and navigating the local regulatory environment at the earliest stages of an intervention. Overall, these findings indicate that although some key planning and supply activities are generally undertaken, improvements are needed to plan for effective scale-up. Much still needs to be learned on MNP planning, and we propose a set of research questions that require further investigation.
