Full textFacing to increasing survival of very preterm neonates, reducing sequelae in this population became a major public issue. Nutritional support of preterm neonates has a durable impact on their future. However, it often fails to prevent the protein-energetic imbalance, nutritional deficiencies, and post-natal growth restriction, which act as aggravating factors. Our researches evaluated different axes of current nutritional strategies, limitations and possible improvements: I) parenteral, II) enteral, III) prevention of complications, IV) growth assessment. Most relevant findings of these clinical studies were: I) Significant variations of parenteral intakes in the centres, as well as inadequate use of lipids, involved in early energetic-protein deficit. Impact of lipids on growth, brain development, and even the incidence of complications were suggested. II) Advantages in using fresh raw mother's own milk in the early days to enhance breastfeeding in hospitalized neonates, as well as important changes in mother's milk composition. An increase in breastfeeding rates over the periods of studies showed a beneficial effect of the research, although "observational", on breastfeeding. III) An increased risk of hyperglycemia in case of low phosphatemia. IV) A moderate impact of being small for gestational age on neuro-development in a preterm cohort, and related auxologic limitations. This work allowed to recognize some barriers of the nutritional support, and to consider different improvement strategies. It emphasizes the close and important links between nutrition, growth and neurological development of vulnerable infants. Further efforts are needed to optimize knowledge, recommendations and practices in this area

Full textThe prevalence of low birth weight, preterm birth and IUGR in our study population were 9.1%, 10.3% and 25.3% respectively. The majority of children born with LBW (75%) had IUGR. Concerning prematurity, only the sex of the child was associated with a lower risk. Conversely, boys were more at risk of IUGR. Primiparous and those with low anthropometric status were more likely to give birth to children with LBW and this was expressed mainly by IUGR mechanism. The same analysis on birth weight as continuous variable gave similar results and showed in addition, an independent negative effect of maternal short stature (<155cm). We did not find an effect of placental malaria infection or maternal anemia. Children born with LBW, IUGR and those from mother with nutritional deficiency showed a linear growth retardation. We also demonstrated that LBW and low anthropometric status of the mother were significantly correlated with leanness. Malaria morbidity was not associated with growth. Good feeding practices objectified by a good IYCF score, were accompanied by a proper corpulence, while they were paradoxically associated with a linear growth delay. Maternal nutritional deficiency (low anthropometric status or short stature) is involved in the occurrence of LBW but also impacted negatively children’s growth through an independent effect. Our results confirm the existence of an intergenerational cycle of malnutrition

Full textNumerous studies have evaluated the effects of maternal physical activity on infant’s birth weight, an important pregnancy outcome reflecting the quality of the prenatal environment and associated with future cardiovascular and obesity risk. Given the alarming worldwide prevalence of childhood obesity, identifying effective preventive strategies becomes a major target in the fight against obesity and its complications. Maternal physical activity could be a promising avenue, considering its positive impact on gestational weight gain and maternal metabolic profile and its potential to decrease birth weight. Nevertheless, the optimal physical activity dose and its effect on infant’s body composition remain unknown. Moreover, most pregnant women do not reach recommended levels of physical activity and obese women, in whom physical activity could be most beneficial, are usually the least active pregnant women. Intriguingly, few physical activity interventions during pregnancy have focused on this population. Thus, before considering physical activity as non-pharmacological therapeutic intervention for pregnant women, a meticulous examination of its safety and effects is required, especially regarding the specificity of the effects of various physical activity stimuli (of different type, volume, intensity and timing) on fetal growth. Also, assessing the feasibility of an intervention aiming at increasing physical activity levels in obese pregnant women appears mandatory. In this context, we first performed a systematic review of observational studies focusing on the association between maternal physical activity and parameters of infant’s growth. Second, two cohort studies were conducted to complement and deepen findings from the systematic review. Finally, a physical activity randomised trial was completed with obese pregnant women to evaluate if such interventions can increase physical activity levels. The present work suggested that different maternal physical activity exposures exert a differential influence on neonatal anthropometry. The systematic review showed that moderate doses of physical activity were associated with an increased birth weight compared with lower doses, while high physical activity doses were associated with a decreased birth weight. Also, the association between maternal physical activity and birth weight was shown to differ in the presence of specific maternal characteristics. Notably, vigorous intensity physical activity in early pregnancy was associated with an important decrease in the birth weight of neonates born to women later diagnosed with preeclampsia. The importance of physical activity intensity in the maternal physical activity-fetal growth relationship was also emphasized by the results of our cohort study with neonatal body composition analysis. Unlike moderate intensity physical activity, vigorous intensity physical activity in early pregnancy seems responsible for the reduction in infant’s birth weight, mainly through a decreased neonatal adiposity. Finally, results from the randomised trial established the feasibility of a supervised physical activity intervention aiming at increasing physical activity levels in obese pregnant women and suggested that this kind of intervention can positively influence fitness and gestational weight gain in these women. Globally, these results contribute to a better understanding of the impact of maternal physical activity on fetal growth, considering specific characteristics of the physical activity stimulus and studied population. The feasibility of a physical activity intervention designed for obese pregnant women might provide new exciting possibilities for childhood obesity prevention. Ascertaining the optimal maternal physical activity dose allowing the improvement of a child’s short and long term health in various pregnant populations and identifying factors associated with a better adherence to physical activity guidelines during pregnancy are essential research avenues that can contribute to tackle the obesity epidemic.

Full textObjectives: To assess the correlation between placental volume, measured by three dimensional ultrasound in the first trimester of pregnancy and birth weight. Methodology: A prospective cohort recruiting 543 women between 11 and 13 weeks gestation was conducted. We evaluated the correlation between placental volume measured by three- dimensional ultrasound (reported as multiple of the median for gestational age), and birth weight (reported in percentile). Data were analyzed using non-parametric tests (Spearman, Mann-Whitney, Kruskal- Wallis), with a significant p value under 0,05. Results: A total of 554 women were recruited. The placental volume showed significant correlation with birth weight (Correlation coefficient (CC); 0,15; p<0.0001). The placental volume was not associated with preeclampsia. Conclusion: There is a significant correlation between placental volume and birth weight. In this study, no correlation was found between placental volume and preeclampsia.

Full textLow birth weight (LBW) is a risk factor for cardiovascular disease in adulthood. However, the mechanisms explaining cardiovascular programming are incompletely understood. In adults, a reduced level of circulating endothelial progenitor cells (EPCs) is correlated with cardiovascular disease and independently predicts atherosclerosis disease progression. Recent studies demonstrated an impairment of vascular structure (microvascular rarefaction) and function (impaired vasodilation) in LBW neonates. Thus, we hypothesized that LBW infants display an EPCs impairment.We demonstrated an alteration of clonogenic and angiogenic capacities of EPCs fropm LBW infants, both in vitro and in vivo. This could be due to a fetal antiangiogenic imbalance and a subsequent antiangiogenic gene expression profile in EPCs of LBW infants. Through an inhibition of Akt/PI3K signaling, an upregulation of thrombospondin-1 expression could partially explain such observations. Moreover, VEGF pathway, the main angiogenesis regulator, could be involved as we found reduced circulating levels of VEGF, probably due to an increase of its main inhibitor, sFlt1 (soluble receptor of VEGF 1) in LBW infants. The addition of VEGF reversed the in vitro negative effect of LBW infants' sera on EPCs angiogenic function.This investigation opens the way for more studies of EPCs function in LBW subjects. Indeed, many questions emerged about the impact of such dysfunction on the future health of LBW infants

Full textEvidence suggest that low birth weight and/or postnatal catch-up growth increase the risk for long term cardiovascular diseases (hypertension especially). Their role on the progression of chronic kidney disease is less evident. The mechanism is incompletely known. Nephron number deficit, associated with low birth weight, may play an important role. In such a condition, an adaptative single nephron glomerular hyperfiltration to meet excretory demands may lead overtime to renal damages. However this hypothesis is still questionable.In the rat, through two experimental models of intrauterine growth restriction (IUGR), we have shown that adverse long term vascular and renal functions are highly dependent on the severity of nephron number deficit. Moreover, we have demonstrated that a rapid neonatal catch-up growth plays a determinant role. Neonatal overfeeding and a high protein diet following IUGR accelerate the expression of hypertension and the progression of chronic kidney disease. Long term vascular and renal diseases may thus result from a mismatch between adverse fetal environment and postnatal beneficial environment. In human prospective epidemiological studies are needed with the aim to evaluate the effect of postnatal nutrition and to determine early markers for future preventive studies
