Lipid-Laden Alveolar Macrophages and pH Monitoring in Gastroesophageal Reflux-Related Respiratory Symptoms.

Lipid-laden alveolar macrophages and pH monitoring have been used in the diagnosis of chronic aspiration in children with gastroesophageal reflux (GER). This study was conducted to prove a correlation between the detection of alimentary pulmonary fat phagocytosis and an increasing amount of proximal gastroesophageal reflux. It was assumed that proximal gastroesophageal reflux better correlates with aspiration than distal GER.

The low-dose ACTH test does not identify mild insufficiency of the hypothalamnic-pituitary-adrenal axis in children with inadequate stress response.

Objective: To investigate retrospectively the sensitivity of published cortisol cut-off points of the low-dose ACTH test (LDAT) in children with proven mild hypothalamic-pituitary-adrenal (HPA) axis insufficiency.

Patients And Methods: The HPA axis of 11 pediatric patients (age range: 5.5-14.

Reactive oxygen species abrogate the anticarcinogenic effect of eicosapentaenoic acid in Atm-deficient mice.

Recent studies have demonstrated that n-3 polyunsaturated fatty acids such as eicosapentaenoic acid (EPA) are able to suppress cell proliferation and inhibit tumor growth. The objective of our study was to investigate the influence of a high dose EPA on the development of the tumor phenotype in ataxia-telangiectasia mutated (Atm)-deficient mice, a genetic cancer model that is associated with increased levels of oxidative stress. We analyzed toxicity, proliferation, cell-cycle progression, and apoptosis of EPA in vitro and latency to tumorigenesis in vivo.

Serum vitamin B(12) concentrations among mothers and newborns and follow-up study to assess implication on the growth velocity and the urinary methylmalonic acid excretion.

Objective: Cobalamin (B(12)) deficiency has been reported in infants born to mothers with low cobalamin intake. Early diagnosis of vitamin B(12) deficiency in infants is critical for the prevention of neurobehavioral disorders. We investigated the relationship between serum vitamin B(12) level in newborns and in their healthy mothers who consumed an omnivorous diet.

Amino acids - Guidelines on Parenteral Nutrition, Chapter 4.

Protein catabolism should be reduced and protein synthesis promoted with parenteral nutrion (PN). Amino acid (AA) solutions should always be infused with PN. Standard AA solutions are generally used, whereas specially adapted AA solutions may be required in certain conditions such as severe disorders of AA utilisation or in inborn errors of AA metabolism.
