Background: Food-assisted maternal and child health and nutrition (FA-MCHN) programs are widely used to address undernutrition, but little is known about their effectiveness in improving child linear growth. Objective: We assessed the impact of Burundi's Tubaramure FA-MCHN program on linear growth. The program targeted women and their children during the first 1000 d and included 1) food rations, 2) strengthening of health services and promotion of their use, and 3) behavior change communication (BCC)...

The pathophysiological mechanisms underlying the origin of several ovarian pathologies remain unclear. In addition to the genetic basis, developmental insults are gaining attention as a basis for the origin of these pathologies. Such early insults include maternal over or under nutrition, stress, and exposure to environmental chemicals. This chapter reviews the development and physiological function of the ovary, the known ovarian pathologies, the developmental check points of ovarian differentiation impacted by developmental insults, the role played by steroidal and metabolic factors as mediaries, the epigenetic mechanisms via which these mediaries induce their effects, and the knowledge gaps for targeting future studies to ultimately aid in the development of improved treatments...

During the past decades, the use/misuse of opioids has increased dramatically among adolescent population. It is now well acknowledged that various morphological and physiological changes occur in the brain during adolescence. During this critical period, brain development and maturation could be affected by several factors including stress, drug abuse, nutritional status, etc. Although studies on transgenerational effects of substances such as alcohol, nicotine, and cocaine have focused on both paternal and maternal drug exposure, most reports on transgenerational effects of morphine are restricted to maternal exposure...

Maternal nutrition during critical gestation periods impacts on offspring in later life; effects of high-starch maternal diet on testicular development in lambs were addressed. Dairy ewes were fed diets providing either 27% (Starch, S) or 11% (Fiber, F) of starch from mating to lambing (∼147 days; S147, F147) or for the last 75 days of gestation (S75, F75). Testes of single male lambs were measured and then sampled for histological and gene expression analyses at selected ages. Testicular dimensions and weight were similar among groups, but the total area of seminiferous tubules increased with age and tended to be higher (P = 0...

Chronic kidney disease affects more than 10% of the population. Programming studies have examined the interrelationship between environmental factors in early life and differences in morbidity and mortality between individuals. A number of important principles has been identified, namely permanent structural modifications of organs and cells, long-lasting adjustments of endocrine regulatory circuits, as well as altered gene transcription. Risk factors include intrauterine deficiencies by disturbed placental function or maternal malnutrition, prematurity, intrauterine and postnatal stress, intrauterine and postnatal overnutrition, as well as dietary dysbalances in postnatal life...

The fetal origins of health and disease framework has identified extremes in fetal growth and birth weight as factors associated with the lifelong generation of chronic diseases such as obesity, diabetes, cardiovascular disease, and hypertension. Maternal nutrition plays a critical role in fetal and placental development, in part by providing the methyl groups required to establish the fetus's genome structure and function, notably through DNA methylation. The goal of this narrative review is to describe the role of maternal dietary methyl donor (methionine, folate, and choline) and cofactor (zinc and vitamins B2, B6, and B12) intake in one-carbon metabolism and DNA methylation in the fetus and placenta, as well as their impacts on fetal growth and lifelong health outcomes, with specific examples in animals and humans...

BACKGROUND: Maternal and child undernutrition have adverse consequences for pregnancy outcomes and child morbidity and mortality, and they are associated with low educational attainment, economic productivity as an adult, and human wellbeing. 'Nutrition-sensitive' agriculture programs could tackle the underlying causes of undernutrition. METHODS/DESIGN: This study is a four-arm cluster randomised controlled trial in Odisha, India. Interventions are as follows: (1) an agricultural extension platform of women's groups viewing and discussing videos on nutrition-sensitive agriculture (NSA) practices, and follow-up visits to women at home to encourage the adoption of new practices shown in the videos; (2) women's groups viewing and discussing videos on NSA and nutrition-specific practices, with follow-up visits; and (3) women's groups viewing and discussing videos on NSA and nutrition-specific practices combined with a cycle of Participatory Learning and Action meetings, with follow-up visits...

Improving maternal and child nutrition in resource-poor settings requires effective use of limited resources, but priority-setting is constrained by limited information about program costs and impacts, especially for interventions designed to improve diet quality. This study utilized a mixed methods approach to identify, describe and estimate the potential costs and impacts on child dietary intake of 12 nutrition-sensitive programs in Ethiopia, Nigeria and India. These potential interventions included conditional livestock and cash transfers, media and education, complementary food processing and sales, household production and food pricing programs...

The paternal transmission of environmentally induced phenotypes across generations has been reported to occur following a number of qualitatively different exposures and appear to be driven, at least in part, by epigenetic factors that are inherited via the sperm. However, previous studies of paternal germline transmission have not addressed the role of mothers in the propagation of paternal effects to offspring. We hypothesized that paternal exposure to nutritional restriction would impact male mate quality and subsequent maternal reproductive investment with consequences for the transmission of paternal germline effects...

In the 1980s, mouse nuclear transplantation experiments revealed that both male and female parental genomes are required for successful development to term ( McGrath and Solter, 1983; Surani and Barton, 1983). This non-equivalence of parental genomes is because imprinted genes are predominantly expressed from only one parental chromosome. Uniparental inheritance of these genomic regions causes paediatric growth disorders such as Beckwith-Wiedemann and Silver-Russell syndromes (reviewed in Peters, 2014). More than 100 imprinted genes have now been discovered and the functions of many of these genes have been assessed in murine models...

BACKGROUND: Breast milk is the sole nutrition source during exclusive breastfeeding, and polyunsaturated fatty acids (FAs) are critical micronutrients in infant physical and cognitive development. There has been no prior genomewide association study of breast milk, hence our objective was to test for genetic association with breast milk FA composition. METHODS: We measured the fractional composition of 26 individual FAs in breast milk samples from three cohorts totalling 1142 Bangladeshi mothers whose infants were genotyped on the Illumina MEGA chip and replicated on a custom Affymetrix 30K SNP array (n=616)...

Maternal diet may influence offspring's health, even within well-nourished populations. Amniotic fluid (AF) provides a rational compartment for studies on fetal metabolism. Evidence in animal models indicates that maternal diet affects AF metabolic profile; however, data from human studies are scarce. Therefore, we have explored whether AF content may be influenced by maternal diet, using a validated food-frequency questionnaire and implementing NMR-based metabolomics. Sixty-five AF specimens, from women undergoing second-trimester amniocentesis for prenatal diagnosis, were analysed...

Developmental programming phenotypes can be recapitulated in subsequent generations not directly exposed to the initial suboptimal intrauterine environment. A maternal low-protein diet during pregnancy and postnatal catch-up growth ('recuperated') alters insulin signaling and inflammation in rat offspring (F1-generation). We aimed to establish if this phenotype is also present in F2-generation females. Insulin-receptor-substrate-1 protein expression was decreased in para-ovarian adipose tissue at 3 months in offspring exposed to a grand-maternal low-protein diet (F2-recuperated), vs...

The development of a proper neonatal microbiota is of great importance, especially for the effects that dysbiosis has in acute and chronic diseases' onset. The microbiota, particularly the intestinal one, plays a crucial role in maintaining the health of the host, preventing colonization by pathogenic bacteria and significantly influencing the development and maturation of a normal gastrointestinal mucosal immunity. Several factors may interfere with the physiological development of microbiota, such as diseases during pregnancy, type of delivery, maternal nutrition, type of neonatal feeding, use of antibiotics, exposition to hospital environment (e...

The introduction of solid food is necessary for any infant in order to provide adequate nutrition because when they grow up milk is insufficient for their nutritional needs. Infants born preterm have increased nutritional requirements. The high nutrient demands as well as the organ immaturity of preterm infants combine to render it difficult to achieve dietary intakes that will allow preterm infants to match their in utero growth rates. Current guidelines for the introduction of solid food to term infants cannot be directly translated to preterm infants...

BACKGROUND: Necrotizing enterocolitis (NEC) is a leading cause of newborn gastrointestinal emergencies, affecting 1-3 per 1000 live births. Although NEC has been linked to a microbial etiology, associations with maternal intrapartum and resultant newborn early-onset invasive Group B streptococcus (EO-GBS) have been weakly defined. OBJECTIVE: The study aim was to determine the relationship between EO-GBS and NEC. STUDY DESIGN: Data from 2008 to 2015 were collected from pediatric records with ICD diagnosis codes consistent with all stages of NEC, with the exception of neonatal EO-GBS data (only available 2011-2015)...
