Filter by:The goal of this observational study is to determine the micronutrient levels in patients in the Pediatric Palliative Care Clinic. The main question it aims to answer are: • What is the frequency of micronutrient deficiencies in pediatric palliative care patients?
The objective of this study is to determine the suitability of lactocytes derived from human breast milk for gene expression analysis, and to explore whether there are any correlations between gene expression and the micronutrient composition of breast milk.
This project will assess the effect of Huel Food replacement on the micronutrient status of healthy volunteers over a 4-week period. To achieve this, 30 (non-smoking) generally healthy volunteers will be recruited to attend the study centre on three separate occasions. Volunteers will be asked to consume their normal diet for one week whilst recording what they eat. They will then be asked to only consume Huel Powder and water for 4 weeks.
Our earlier research has highlighted a high prevalence of anaemia, micronutrient deficiencies, and impaired infant growth among lactating women and infants in Sumedang district, West Java, Indonesia that were associated with large deficits in their micronutrient intakes. In response to these disturbing findings we have developed the micronutrient- enriched crackers (MEC) based on powdered eggshells and chicken liver, a readily available and affordable, local animal-source food. We will supply these MEC or a placebo, manufactured locally, weekly to a group of women in Sumedang district from 8-14 weeks gestation to 5 months post-partum in an effort to enrich the micronutrient content of the daily diets of the treatment group so they no longer have any dietary shortfalls in micronutrients. Our overall aim is to determine if MEC consumed daily by mothers for 6 months during pregnancy improves the birth length of their infants, and if daily consumption of MEC is continued daily to 5 months post-partum enhances infant linear growth compared to the placebo. This study is funded by the UK Wellcome Trust, the grant reference number is 216447/Z/19/Z.
The aim of the research project is to investigate the uptake of omega-3 fatty acids into the blood plasma through the consumption of the microalgae Phaeodactylum tricornutum (PT) in a human study. In an open, crossover study, the volunteers will receive a drink enriched with the microalgae P. tricornutum or an omega-3 fatty acid preparation or (optionally) pollock for 14 days each. Since the microalgae P. tricornutum is rich in omega-3 fatty acids, the target parameter chosen is the uptake of omega-3 fatty acids in the blood plasma
The overall goal of this study is to examine the influence of the menstrual cycle on micronutrient concentrations and plasma volume in healthy, reproductive-age women with regular cycles. The investigators aim to quantify changes in micronutrient biomarker concentrations (zinc, copper, iron, and vitamin A) and plasma volume across the menstrual cycle in healthy women.
Large-scale zinc supplementation studies have demonstrated highly significant positive effects on growth, morbidity and mortality in infants who are born small for gestational age (SGA). This suggests these infants may have higher postnatal requirements compared to appropriate for gestational age (AGA) infants, possibly due to inadequate zinc intake from breast milk due either to lower volume or to differences in milk zinc concentrations from mothers of SGA compared to AGA infants. Alternatively, SGA infants may have lower zinc stores at birth, which may reflect a greater postnatal requirement for optimal zinc status. It is thus possible that the zinc requirements of the SGA infant exceed the zinc intake that can be achieved from exclusive breastfeeding, which is recommended for the first 6 mo of life. The exchangeable zinc pool (EZP) is defined as the estimate of the total size of the combined pools of zinc that exchange with zinc in plasma within approximately 2-3 days and may also differ between SGA and AGA infants. 1. Compare longitudinal zinc intake by measuring milk zinc concentrations and volume of intake of breast milk between SGA and AGA infants through first 12 mo. 2. Compare post-natal growth rates for SGA and AGA infants through the first 12 mo of life in relation to zinc intake. 3. Compare size of exchangeable zinc pool (EZP) at birth and at 6 mo of age between SGA and AGA infants. Hypotheses: 1. Zinc concentrations in human milk will not be significantly different at any stage of lactation between mothers of SGA infants and mothers of AGA infants. 2. The volume of breast milk intake relative to body weight will be similar between SGA and AGA infants, but the total intake will be lower in SGA infants. 3. Linear growth rates, rate of weight gain, and rate of growth in head circumference will be significantly lower in infants born SGA, and will be positively correlated with total daily zinc intake. 4. The size of the EZP at birth will be significantly smaller in absolute size and relative to body weight in infants born SGA compared to AGA
At the moment, most of efforts to prevent non-transmissible chronic diseases at population level have been centered in promoting healthful behaviors like physical activity, consumption of fruits and vegetables, and discouraging from the consumption of tobacco and alcohol in adult population, but the results have been little hopeful. In the last years, manifold studies have indicated the relation between metabolic alterations and of the fetal growth with the development of non-transmissible chronic diseases in adult age. More recently, it has been proposed that maternal factors (endothelial function, oxidative stress and alterations in adipokines) and placental ones (mitochondrial dysfunction) are the precursory mechanisms of fetal metabolic alterations and of the later development of non-transmissible chronic diseases. Also, it has been suggested that possibly supplementation with micronutrients and the physical exercise during the gestation can regulate these maternal and placental factors. For the reasons just mentioned, it is necessary to clarify if these proposed factors are related to fetal metabolic alterations and if the supplementation during the gestation with micronutrients and/or the physical exercise can regulate them, which would be an early and novel alternative to fortify the prevention of non-transmissible chronic diseases in the population. Purpose 1. To evaluate the effect of associated both the maternal and placental metabolic factors to non-transmissible chronic diseases in newborn. 2. To evaluate the effect of the physical exercise and the complementation with micronutrients during the pregnancy either in the endothelial function, the levels of adipokines, the oxidative stress of the mother and the newborn, as in the placental mitochondrial function and the anthropometry of newborn.
1. At 12 mo of age, all three intervention groups will have significantly better iron and vitamin A status than the NI group. 2. Infants who receive the Foodlet or Nutributter will have significantly greater weight and length gains from 6 to 12 mo and higher indices of vitamin B6, riboflavin and zinc status at 12 mo of age than the infants who receive the sprinkles containing iron and vitamin A only. 3. Infants who receive Nutributter will have significantly greater weight and length gains from 6 to 12 mo and higher indices of vitamin A and essential fatty acid (linoleic, alpha-linolenic and docosahexaenoic, DHA) status at 12 mo of age than the infants who receive the Foodlet or sprinkles.
