"A number of epidemiological and experimental studies have shown that impaired intrauterine growth, resulting in low birth weight (less than the 10th percentile), is associated with a variety of adult-onset diseases, including type 2 diabetes, hypertension, hyperlipidemia, cardiovascular disease , stroke           and kidney disease  . "
[Show abstract][Hide abstract] ABSTRACT: Both epidemiological and experimental studies have shown that impaired growth in utero due to maternal malnutrition, resulting in low birth weight, is associated with a high incidence of glucose intolerance, insulin resistance, and type 2 diabetes in adult life. Maternal malnutrition is a worldwide problem and unavoidable; therefore, prevention of type 2 diabetes in low birth weight infants who reach adulthood is difficult to achieve. Administration of human umbilical cord blood (HUCB) mononuclear cells into type 1 and type 2 diabetic mice has been shown to improve both their blood glucose levels and survival. It has also been shown that the progenitor cells derived from HUCB improve not only glycemia but also other disease conditions, including systemic lupus erythematosis, amyotrophic lateral sclerosis, Alzheimer's disease, stroke, brain damage in animals and certain malignancies in humans. Transfusion of unrelated HUCB, although abundantly available, is underutilized as a therapeutic agent. Therefore, we propose the hypothesis that transfusion of HUCB to low birth weight infants be considered a therapeutic modality to prevent the development of type 2 diabetes in their adulthood.

[Show abstract][Hide abstract] ABSTRACT: L'exposition à la lumière des solutions de nutrition parentérale (NP) génère des peroxydes tels que l'H2O2 et l'ascorbylperoxyde (AscOOH). Cette absence de photo-protection provoque une augmentation des triglycérides (TG) plasmatique chez les enfants prématurés et chez un modèle animal, ayant un stress oxydatif et une stéatose hépatique indépendante de l’exposition au H2O2. Nous pensons que l'AscOOH est l'agent actif conduisant à l'élévation des TG. Le but est d'investiguer le rôle de l'AscOOH sur les métabolismes du glucose et des lipides à l'aide d'un modèle animal néonatal de NP. The light exposure of parenteral nutritive solutions generates peroxides such as H2O2 and ascorbylperoxide. This absence of photo-protection is associated with higher plasma triacylglycerol concentration (TG) in premature infants and, in animals, with oxidative stress and a H2O2 independent hepatic steatosis. We hypothesized that ascorbylperoxide is the active agent leading to high TG. The aim was to investigate the role of ascorbylperoxide on glucose and lipid metabolism in an animal model of neonatal parenteral nutrition.
[Show abstract][Hide abstract] ABSTRACT: An association between low birth weight, commonly a reflection of an adverse in utero environment, and the subsequent development of diseases such as type 2 diabetes and hypertension in later life is now generally accepted - as is an association between an adverse perinatal environment and a permanent reduction in insulin sensitivity. This and other metabolic abnormalities have been demonstrated from childhood through to adulthood in subjects who were born full-term but small for gestational age (SGA). Less is known about children born prematurely into an adverse neonatal environment. We present data demonstrating that premature infants also have metabolic abnormalities similar to those observed in full-term, SGA children, and that these occur irrespective of whether the premature infants are SGA or appropriate for gestational age (AGA).
