Filter by:The purpose of this study is to evaluate the effect of probiotic administration on TPN dependence in infants < 32 weeks GA and BW 1500 grams or less in the Banner - University Medical Center Phoenix and Banner Children's at Desert Neonatal Intensive Care Units (NICU). The primary endpoint of capturing the number of days of TPN administration can reflect that an infant is progressing towards readiness for the initiation or advancement of enteral feedings at an earlier interval. The relationship between probiotic administration and the incidence of NEC, culture positive sepsis, and mortality is of interest to us and will be captured. Finally, the assessment of the tolerance of probiotic administration and the potential positive impact on growth and development in these premature infants may validate our current practices.
Liver transplantation (LT) is one of the widely recognised and leading treatments for end-stage liver disease. Nutrition impacts its success. Total parenteral nutrition (TPN) is usually prescribed for patients recommended prolonged fasting after LT. The supplement of SMOFlipid (soybean oil, MCT oil, olive oil, and fish oil) is easily metabolised to produce energy, and it possesses anti-inflammatory effects; however, SMOFlipid emulsion use raises concerns regarding coagulopathy after LT. This study investigated the postoperative correlation between SMOFlipid and coagulation in LT.
The aim of our study is to compare two ECG techniques for guiding Peripherally Inserted Central Venous Cather (PICC) in terms of accuracy of the final position of the catheter tip.
The aim of this study is to compare two techniques of placing a peripherally inserted central venous catheter (PICC). The first technique, uses ECG based electromagnetic guidance (ECG-EM). The second (reference technique), is guided by X-ray (fluoroscopy).
The incidence of preterm birth increases annually. Premature delivery has become the leading cause of neonatal illness and death. For the survived premature babies, the incidence of sequelae is also higher than the full-term babies, which brings a heavy burden to a family and society. Preterm birth has become the important factor affecting the quality of births. The occurrence of premature birth is the outcome of combined action of genetic and environmental factors. However, its etiology is not clear. Recent studies have shown that the risk of preterm birth is associated with dietary factors. Choline is an essential nutrient for human health and it plays an important role in the growth and development of fetuses and neonates. The investigators previously found that serum levels of free choline in preterm mothers were lower than those in normal mothers with full-term birth. Serum levels of free choline also reduced in preterms after receiving parenteral nutrition (PN). However, the relationships between choline and preterm birth is not clear. Therefore, this study is aimed to explore the effect of choline intake during pregnancy and genetic polymorphisms on the risk of preterm birth and on the clinical outcomes in preterms receiving total PN therapy. Healthy Chinese pregnant women with their healthy term infants will be recruited as the control group, while Chinese women with preterm delivery and their preterm infants will be recruited as the preterm group. Dietary choline intake during pregnancy will be evaluated by semi-quantitative food frequency questionnaire and 24-h dietary recall questionnaire. Gene polymorphisms in the key enzymes of choline metabolism will be identified among the participated women and neonates through Real-time polymerase chain reaction. Choline and its related metabolites will be assayed using high performance liquid chromatography combined with mass spectrometry among all mothers and preterms before and after 7-days PN treatment. The influence of genetic risk factors and metabolic changes of choline on the physical and mental development of preterms will be evaluated. The results of this study will contribute to a comprehensive understanding of the role of choline and the relative gene polymorphisms on the risk of preterm birth, which will be helpful for estimating the high risk in advance. The results will also provide the scientific evidences to establish the personalized amount of choline intake among women and infants, optimize nutrition support for pregnant women and preterms, and promote better prenatal and postnatal care.
Immune modulating properties of parenteral lipid emulsions seem to contribute to the increased risk for infections which remains associated with the use of total parenteral nutrition. Emulsions based on soy bean oil (SO) are the oldest and still most widely used lipid source in TPN formulations but their high content of omega-6 polyunsaturated fatty acids (PUFAs) may be a drawback. Fish oil-based lipid emulsions (FO), rich in omega-3 PUFAs, has been approved for parenteral nutrition in many countries. Mainly retrospective studies on clinical outcomes in septic and postoperative patients have suggested clinical benefits with the inclusion of FO in parenteral nutrition regimens. The exact mechanisms behind the beneficial immunological effects of parenteral FO have, however, not yet been elucidated. Objective: To evaluate the effects of intravenous infusion of a FO-based lipid emulsion and a SO-based emulsion on immune function as evidenced by effects on peripheral blood leukocyte counts and functions and on the susceptibility to oxidative stress. Study design: Randomized placebo controlled cross-over pilot study with healthy volunteers.
