Filter by:The study aims to establish lysine requirements using the indicator amino acid oxidation (IAAO) method in women exclusively breastfeeding a single infant aged 3-4 months, and how maternal lysine needs change once infant transition to complimentary feeding at a later age of 9-10 months. Each 8-hour study day will have an assigned test lysine intake ranging from deficient to excess. The diets will be provided in a complete protein shake format, meeting all nutrient requirements except for the test lysine intake. Breath samples evaluate the indicator's oxidation to determine protein synthesis in response to lysine intake. Urine and one blood sample will be collected to assess metabolite concentrations.
This is an open label study to investigate PK of tenapanor and AZ13792925 in breast milk of lactating female subjects.
This is a prospective, non-randomized, phase I study design evaluating the in vivo activities and expression of OCT1 and BCRP in mammary gland of lactating women at three time points postpartum.
Iron requirements increase significantly during pregnancy. Current recommendations for iron intake in pregnant and lactating women (PLW) are mainly based on factorial estimates and extrapolated from non-PLW. High-quality quantitative data on iron requirements in PLW are lacking, particularly in Sub- Saharan Africa where anaemia and infections are common. The primary objective of this study is to use the stable iron isotope technique to determine iron requirements and assess iron absorption and losses in PLW living in Kenya. In this prospective observational study, we will enrol pregnant women in the first trimester (n = 250) from a previous study cohort (n=1000) who participated in an iron absorption study at least 12 months ago and received the stable iron (Fe) isotope 57Fe. This 57Fe has now distributed and equilibrated throughout the women's body iron. Once enrolled in the present study, following Kenyan guidelines, women will receive standard prenatal care, including routine daily iron and folate supplementation. We will collect venous blood samples in each trimester and at delivery, and during the first 6 months of lactation in the mothers and infants (heel prick samples). To directly assess dietary iron absorption, in a randomly selected subset of women (n=35), oral and intravenous stable iron isotope tracers (54Fe, 58Fe) will be administered in the 2nd and 3rd trimesters.
The objective of this study are to evaluate efficacy and safety of milk secretory supplement containing fenugreek, banana flower, and ginger extract in breast-feeding volunteers
The aim of the present study is to evaluate the effect of consumption during pregnancy and the lactation period of the probiotic L. fermentum CECT5716 on the incidence of mastitis. Bacterial load and immunological parameters in breast milk, parameters related to breastfeeding as well as health parameters of the mother and baby will also be evaluated.
Feeding human milk to preterm infants does reduce the risk of serious and costly neonatal intensive care unit acquired morbidity such as NEC and the late onset sepsis. It is often difficult to obtain sufficient quantities of human milk from mothers of preterm infants most of whom are breast pump-dependent for weeks or months. Mothers will try to use galactogogues in an attempt to increase milk production. Fenugreek (Trigonella foenum-graecum) seeds is the most commonly used herbal galactogogue and is a member of the pea family. Our experience at the NICU is that around 30% of preterm mothers desperately looking for ways to increase their breast milk supply will eventually took fenugreek (Hilbe) as food supplement. Although widely recommended, there is limited evidence to support the effectiveness of fenugreek as a galactogogue. The aims of this study are to evaluate whether maternal consumption of fenugreek seeds has any effect on macronutrients composition of breast milk and whether fenugreek is transferred to the infant via mother milk. In addition any changes in mother and infant health status will be assessed.
Background: The childbearing years are a time of increased vulnerability to the onset of mood disorders in women and a high prevalence of exposure to antidepressant drugs during pregnancy and postpartum has been reported. However, the lack of information regarding the milk transfer and the safety of these drugs in breastfed infants and the related fear of adverse events for the sucking infant are some of the factors responsible for stopping prematurely breast-feeding or avoiding drug therapy. Selective serotonin reuptake inhibitors (SSRI) and selective serotonin and noradrenaline reuptake inhibitors (SNRI) are the most frequently prescribed antidepressant drugs during pregnancy and the post-partum period. They exhibit a wide interpatient variability in their concentration profiles that has been related to numerous environmental, stereochemical, demographic and genetic influences that might alter the level of exposure of breastfed newborns. Limited information is available regarding the safety of use of these antidepressant drugs during lactation, and is generally derived from small studies. A comprehensive description of their distribution and quantification in milk in a larger cohort of patients under various influences and the resulting impact on milk concentrations is lacking. Objectives: The current proposal addresses the primary objectives of quantifying the range of concentration to citalopram, escitalopram, sertraline, fluoxetine, paroxetine, fluvoxamine, duloxetine and venlafaxine in mother plasma and breast milk in relation to genetic polymorphisms, stereochemistry, demographics and environmental factors in a large cohort of depressive mothers. This will enable to derive the exposure to the breast-fed child taking into account this variability and therefore better adjust treatment to potential influences. As secondary objectives, we will examine the neurodevelopmental outcome of a sub-set of infants subjected to SSRI/SNRI in utero and/or during breastfeeding at birth, 6, 18 and 36 months, and compared to that of a control population of infants not subjected to this treatment. Expected Results: The proposed strategy will offer new information regarding the expected level of drug exposure associated with each or with a combination of risk factors and help for optimizing the security and rationalizing the use of antidepressant treatment in lactating women. Hence, research on the safety of use of these drugs for the developing child is an area of great public health significance.
