Update on the Transmission of Zika Virus Through Breast Milk and Breastfeeding: A Systematic Review of the Evidence.

We systematically searched regional and international databases and screened 1658 non-duplicate records describing women with suspected or confirmed ZIKV infection, intending to breastfeed or give breast milk to an infant to examine the potential of mother-to-child transmission of Zika virus (ZIKV) through breast milk or breastfeeding-related practices. Fourteen studies met our inclusion criteria and inform this analysis. These studies reported on 97 mother-children pairs who provided breast milk for ZIKV assessment.

Clinical manifestations, prevalence, risk factors, outcomes, transmission, diagnosis and treatment of COVID-19 in pregnancy and postpartum: a living systematic review protocol.

Introduction: Rapid, robust and continually updated evidence synthesis is required to inform management of COVID-19 in pregnant and postpartum women and to keep pace with the emerging evidence during the pandemic.

Methods And Analysis: We plan to undertake a living systematic review to assess the prevalence, clinical manifestations, risk factors, rates of maternal and perinatal complications, potential for mother-to-child transmission, accuracy of diagnostic tests and effectiveness of treatment for COVID-19 in pregnant and postpartum women (including after miscarriage or abortion). We will search Medline, Embase, WHO COVID-19 database, preprint servers, the China National Knowledge Infrastructure system and Wanfang databases from 1 December 2019.

Presence of Ebola virus in breast milk and risk of mother-to-child transmission: synthesis of evidence.

To help inform global guidelines on infant feeding, this systematic review synthesizes evidence related to the presence of the Ebola virus (EBOV) in breast milk and its potential risk of viral transmission to the infant when breastfeeding. We relied on a comprehensive search strategy to identify studies including women with suspected, probable, or confirmed EBOV infection, intending to breastfeed or give breast milk to an infant. Our search identified 10,454 records, and after deduplication and screening, we assessed 148 full texts.

Transmission of SARS-CoV-2 through breast milk and breastfeeding: a living systematic review.

The pandemic of coronavirus disease 2019 (COVID-19) is caused by infection with a novel coronavirus strain, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). At present, there is limited information on potential transmission of the infection from mother to child, particularly through breast milk and breastfeeding. Here, we provide a living systematic review to capture information that might necessitate changes in the guidance on breast milk and breastfeeding given the uncertainty in this area.

Effectiveness of provision of animal-source foods for supporting optimal growth and development in children 6 to 59 months of age.

Background: Adequate nutrients early in life promote cognitive development and are critical for proper growth and functioning. The effect of individual nutrients consumed through food is often not the same as consuming the same nutrients in supplementary form due to 'food synergy', the biological and chemical interrelations that occur between nutrients. Animal-source foods, such as eggs, meat, fish, and dairy, are energy dense and contain multiple micronutrients and essential fatty acids with high bioavailability.

Deworming in non-pregnant adolescent girls and adult women: a systematic review and meta-analysis.

Background: The impact of deworming on parasite load, nutritional status and other health outcomes of non-pregnant adolescent girls and adult women is uncertain.

Methods: MEDLINE, EMBASE, CINAHL, the Cochrane Central Register of Controlled Trials, the WHO International Clinical Trials Registry Platform, the Cochrane Database of Systematic Reviews and Food and Technology Abstracts databases were searched until 24 September 2018. Studies were included if they were randomised controlled trials (RCTs), controlled before and after studies or interrupted time studies comparing deworming with no intervention or placebo in non-pregnant adolescent girls and women 10 to 49 years old.

Interventions for treating children and adolescents with overweight and obesity: an overview of Cochrane reviews.

Children and adolescents with overweight and obesity are a global health concern. This is an integrative overview of six Cochrane systematic reviews, providing an up-to-date synthesis of the evidence examining interventions for the treatment of children and adolescents with overweight or obesity. The data extraction and quality assessments for each review were conducted by one author and checked by a second.

Health Facility Staff Training for Improving Breastfeeding Outcome: A Systematic Review for Step 2 of the Baby-Friendly Hospital Initiative.

The Baby-Friendly Hospital Initiative (BFHI) implemented through the "Ten Steps to Successful Breastfeeding" has been widely promoted as an intervention that improves breastfeeding rates. Step 2 requires the training of all healthcare staff in skills that are necessary to implement the policy. This systematic review provides evidence about the effect of training healthcare staff in hospitals and birth centers on breastfeeding outcomes.

Factors associated with inflammation in preschool children and women of reproductive age: Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project.

In many settings, populations experience recurrent exposure to inflammatory agents that catalyze fluctuations in the concentrations of acute-phase proteins and certain micronutrient biomarkers such as C-reactive protein (CRP), α-1-acid glycoprotein (AGP), ferritin, and retinol. Few data are available on the prevalence and predictors of inflammation in diverse settings. We aimed to assess the relation between inflammation (CRP concentration >5 mg/L or AGP concentration >1 g/L) and covariates, such as demographics, reported illness, and anthropometric status, in preschool children (PSC) (age range: 6-59 mo) and women of reproductive age (WRA) (age range: 15-49 y).

Predictors of anemia in preschool children: Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project.

A lack of information on the etiology of anemia has hampered the design and monitoring of anemia-control efforts. We aimed to evaluate predictors of anemia in preschool children (PSC) (age range: 6-59 mo) by country and infection-burden category. Cross-sectional data from 16 surveys ( = 29,293) from the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project were analyzed separately and pooled by category of infection burden.

Transmission of Zika virus through breast milk and other breastfeeding-related bodily-fluids: A systematic review.

Background: Zika virus (ZIKV) infection is an emerging mosquito-borne disease, which is associated with an increase in central nervous system malformations and newborn microcephaly cases. This review investigated evidence of breastfeeding transmission from ZIKV-infected mothers to their children and the presence of ZIKV infection in breastfeeding-related fluids.

Methodology/principal Findings: We conducted a systematic review of observational studies, case studies, and surveillance reports involving breastfeeding women with ZIKV infection in several international databases.

Effects and safety of periconceptional oral folate supplementation for preventing birth defects.

Background: It has been reported that neural tube defects (NTD) can be prevented with periconceptional folic acid supplementation. The effects of different doses, forms and schemes of folate supplementation for the prevention of other birth defects and maternal and infant outcomes are unclear.

Objectives: This review aims to examine whether periconceptional folate supplementation reduces the risk of neural tube and other congenital anomalies (including cleft palate) without causing adverse outcomes in mothers or babies.

Maternal nutrition: how is Eastern and Southern Africa faring and what needs to be done?

Background: The progress in key maternal health indicators in the Eastern and Southern Africa Region (ESAR) over the past two decades has been slow.

Objective: This paper analyzed available information on nutrition programs and nutrition-specific interventions targeting maternal nutrition in the ESAR and proposes steps to improve maternal nutrition in this region.

Methods: Search was conducted in relevant databases.

Infant and young child feeding practices in urban Philippines and their associations with stunting, anemia, and deficiencies of iron and vitamin A.

Background: The prevalence of stunting, underweight, and micronutrient deficiencies are persistently high in young children in the Philippines, and among other factors, suboptimal infant and young child feeding behavior may contribute to these forms of malnutrition.

Objective: To improve the understanding of contributors associated with the nutritional status of children 6 to 23 months of age living in urban areas of the Philippines.

Methods: A cross-sectional survey was conducted covering five urban centers in the Philippines.

Home gardening is associated with Filipino preschool children's dietary diversity.

Dietary diversification through home gardening is a sustainable strategy that can address multiple micronutrient deficiencies. This cross-sectional study aimed to determine the association between home gardening and the dietary diversity of preschool-aged children. Households with children aged 2 to 5 years (n=200) were surveyed from Baras and Angono in the province of Rizal, Philippines in January 2008.

Season of conception in rural gambia affects DNA methylation at putative human metastable epialleles.

Throughout most of the mammalian genome, genetically regulated developmental programming establishes diverse yet predictable epigenetic states across differentiated cells and tissues. At metastable epialleles (MEs), conversely, epigenotype is established stochastically in the early embryo then maintained in differentiated lineages, resulting in dramatic and systemic interindividual variation in epigenetic regulation. In the mouse, maternal nutrition affects this process, with permanent phenotypic consequences for the offspring.

Host genetic factors and vaccine-induced immunity to HBV infection: haplotype analysis.

Hepatitis B virus (HBV) infection remains a significant health burden world-wide, although vaccines help decrease this problem. We previously identified associations of single nucleotide polymorphisms in several candidate genes with vaccine-induced peak antibody level (anti-HBs), which is predictive of long-term vaccine efficacy and protection against infection and persistent carriage; here we report on a haplotype-based analysis. A total of 688 SNPs from 117 genes were examined for a two, three and four sliding window haplotype analysis in a Gambian cohort.

Efficacy of pandesal baked from wheat flour fortified with iron and vitamin a in improving the iron and anthropometric status of anemic schoolchildren in the Philippines.

Objective: To determine the efficacy of pandesal baked from wheat flour fortified with iron, with or without vitamin A (VA), in improving anemic schoolchildren's iron and anthropometric status.

Methods: Anemic 6- to 12-year-old Filipino children (n = 250) received two 60 g pandesal daily for 8 months. They were randomized into 1 of 4 groups: (1) iron-fortified (with hydrogen-reduced iron at 80 mg/kg, electrolytic iron at 80 mg/kg, or ferrous fumarate at 40 mg/kg), (2) iron and VA-fortified, (3) VA-fortified (at 490 RE/100 g), and (4) nonfortified flour.

Influence of carotene-rich vegetable meals on the prevalence of anaemia and iron deficiency in Filipino schoolchildren.

Objective: To determine the effects of eating carotene-rich green and yellow vegetables on the prevalence of anaemia, iron deficiency and iron-deficiency anaemia in schoolchildren.

Subjects And Methods: Schoolchildren (n=104), aged 9-12 years, received standardized meals containing 4.2 mg of provitamin A carotenoids/day (mainly beta-carotene) from yellow and green leafy vegetables and at least 7 g dietary fat/day.

Common polymorphic variation in the genetically diverse African insulin gene and its association with size at birth.

The insulin variable number of tandem repeats (INS VNTR) has been variably associated with size at birth in non-African populations. Small size at birth is a major determinant of neonatal mortality, so the INS VNTR may influence survival. We tested the hypothesis, therefore, that genetic variation around the INS VNTR in a rural Gambian population, who experience seasonal variation in nutrition and subsequently birth weight, may be associated with foetal and early growth.

Physical activity, energy requirements, and adequacy of dietary intakes of older persons in a rural Filipino community.

Background: Aging is a process associated with physiological changes such as in body composition, energy expenditure and physical activity. Data on energy and nutrient intake adequacy among elderly is important for disease prevention, health maintenance and program development.

Methods: This descriptive cross-sectional study was designed to determine the energy requirements and adequacy of energy and nutrient intakes of older persons living in private households in a rural Filipino community.

FTO gene variation and measures of body mass in an African population.

Background: Variation in the fat mass and obesity associated (FTO) gene has been reproducibly associated with body mass index (BMI) and obesity in populations of White European origin. Data from Asians and African-Americans is less conclusive.

Methods: We assessed the effect of 16 FTO polymorphisms on body mass in a large population of predominantly lean Gambians (N(max) 2208) participating in a long-term surveillance program providing contemporary and early-life anthropometric measurements.
