We examined the morbidities and oxidative stress statuses in preterms receiving either SMOFlipid or ClinOleic. This observational study was performed in Etlik Zubeyde Hanim Hospital, Turkey. Infants received SMOFlipid (5 months) or ClinOleic (7 months). Two hundred and twenty seven infants (SMOFlipid: 93, ClinOleic: 134) very low birth weighted infants were included. The oxidative stress status was evaluated in infants at low risk of oxidative stress by total antioxidant capacity (TAC) and total oxidant status (TOS) and oxidative stress index (OSI; TAC/TOS/100) at baseline, first week and third week. Parenteral nutrition was given for a median of 7 days in both groups. There were statistically insignificantly higher rates of retinopathy of prematurity (9.4 versus 11.7%) and chronic lung disease (4.7 versus 6.7%) in ClinOleic group compared with SMOFlipid group. The TAC, TOS and OSI decreased significantly in ClinOleic group after 1 week, and although the results were not statistical...

Background: Total parenteral nutrition (TPN) is a life-saving therapy given to neonates with intestinal failure. However, infants on long-term TPN may experience Parenteral Nutrition-Associated Liver Disease (PNALD). New formulations for lipid emulsions are purportedly better than the traditional soy-based lipid emulsions (SLE). Our primary objective was to determine the prevalence of PNALD in infants who received non-soybean-based lipid emulsions (NSLE) or SLE. Methods: In this retrospective study, medical records of all infants admitted to a tertiary neonatal intensive care unitfrom 2004 to 2013 were reviewed. Late preterm (34-36 weeks of gestation) and term infants who were on TPN for more than two weeks were included. Their demographic data and clinical variables were collected. Results: 208 infants received SLE for more than two weeks. The prevalence rate of PNALD in those who received SLE was 21% while that of those who received the NSLE was 17%. No significant difference was found between the 'Soy' or 'NonSoy' subgroups (p = 0.315). Seventy infants received TPN for more than four weeks. The prevalence rate of PNALD in infants who received SLE and NSLE was 35% and 25% respectively. No significant statistical difference was found between the 'Soy' or 'NonSoy' subgroups (p = 0.132). Conclusions: The type of lipid emulsion does not significantly influence the rate of PNALD in late preterm and term infants on long-term TPN.

We assessed the effects of three different parenteral lipid emulsions (long-chain triacylglycerols, medium-chain/long-chain triacylglycerols, olive oil) on lipid peroxidation in preterm infants. The hypothesis to be tested was that preterm infants receiving the olive oil–based lipid emulsion would undergo less peroxidation than preterm infants receiving lipid emulsions based on long- or medium-chain triacylglycerols. The secondary aim was to evaluate whether the lipid peroxidation persists beyond the cessation of parenteral nutrition (PN).A randomized controlled trial was designed. Thirty-six consecutive preterm infants (gestational age 28–33 wk) were enrolled in the study. Preterm infants were randomized to receive one of the three emulsions within the first 24 h of life. Plasma F2-isoprostanes (F2-Ip) and total radical-trapping antioxidant potential (TRAP) were determined at baseline, on day 7 of PN, and on day 7 after stopping PN.The F2-Ip and TRAP concentrations were not statistically different within and among the three groups at any time of the study. No significant interaction effect between the type of lipid emulsion administered and the repeated values of F2-Ip and TRAP was found. F2-Ip values showed a trend to decrease throughout the study in all the three groups.No significant difference in oxidative stress of preterm infants was detected according to the type of lipid emulsion received.

The pure soybean oil based lipid emulsions (S-LE) conventionally used for parenteral nutrition (PN) in preterm infants have high polyunsaturated fatty acid (PUFA) content. The newer lipid emulsions (LE) from alternative lipid sources with reduced PUFA content may improve clinical outcomes in preterm infants. To determine the safety and efficacy of the newer alternative LE compared with the conventional S-LE for PN in preterm infants. We used the standard search strategy of the Cochrane Neonatal Review Group (CNRG) to search the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 7), MEDLINE (1946 to 31 July 2015), EMBASE (1947 to 31 July 2015), CINAHL (1982 to 31 July 2015), Web of Science (31 July 2015), conference proceedings, trial registries (clinicaltrials.gov, controlled-trials.com, WHO's ICTRP), and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.

Intravenous administration of pure soybean oil emulsions high in linoleic acid may lead to inflammation and lipid peroxidation in preterm neonates. We aimed to investigate the effects of a medium-chain triglyceride (MCT)/ω-3 polyunsaturated fatty acid (PUFA)-enriched intravenous fat emulsion (IVFE) on plasma fatty acid (FA) profile and serum interleukin-6 (IL-6) in preterm neonates. In this double-blind randomized study, 92 preterm neonates (gestational age < 32 weeks, birth weight < 1500 g) were assigned to receive either MCT/ω-3 PUFA-enriched IVFE (Intervention Group) or soybean oil-based IVFE (Control Group). Levels of FAs were measured at baseline (day 0) and day 15 of parenteral nutrition with gas-chromatography mass-spectrometry. Serum IL-6 was measured with sandwich ELISA in 59 neonates. Plasma FAs changed significantly over time; the MCT/ω-3 PUFA-IVFE group showed higher ω-3 PUFAs (p = 0.031), eicosapentaenoic acid (p = 0.000), and oleic acid (p = 0.003), and lower ω-6...

Role of parenteral lipid emulsions in the preterm infant
Early Human Development, 2013
Parenteral nutrition (PN) is necessary for infants unable to receive adequate calories enterally due to prematurity, decreased bowel length, or functional intestinal disorders. While PN can be life saving, its use is associated with significant risks of sepsis from catheter-associated infections and progressive liver dysfunction from prolonged use. The preterm infant population is at highest risk for these complications due to the presence of multiple comorbidities and immaturity of the biliary system. Strong data has implicated parenteral lipids in the multifactorial pathogenesis of PN-associated liver disease (PNALD). However, lipids are essential in early infant development, particularly in the neurocognitive development of preterm infants. Substitution of the lipid source from soybean oil to fish oil has emerged as a safe and efficacious treatment of PNALD, with marked improvements in morbidity and mortality. Knowledge of the developmental needs and physiologic limitations of preterm infants is crucial to optimizing parenteral lipid administration to nurture growth, and minimize and treat associated complications. The purpose of this review is to provide an overview of lipid requirements of the preterm infant and discuss the role of parenteral lipid emulsions in the management of PNALD and other diseases of prematurity.

Background: The efficacy of micronutrient supplementation in improving childhood health and survival in developing countries may be specific to the micronutrient used and health outcome measured. Objective: We evaluated the effect of vitamin A and zinc supplementation on overall rates of childhood diarrheal disease and respiratory tract infections and rates stratified by household and personal characteristics. Design: A double-blind, randomized, placebo-controlled trial was carried out in which 736 children aged 6 -15 mo living in a periurban area of Mexico City were assigned to receive vitamin A every 2 mo, zinc daily, vitamin A and zinc together, or placebo. Children were followed for 12 mo to determine overall counts of diarrheal episodes and respiratory tract infections. Results: Vitamin A supplementation was associated with a 27% increase in diarrheal disease [risk ratio (RR): 1.27; 95% CI: 1.10, 1.45; P 0.001] and a 23% increase in cough with fever (RR: 1.23; 95% CI: 1.02, 1.47; P ҃ 0.02), whereas zinc had no effect on these outcomes. Vitamin A supplementation decreased diarrhea in children from households with dirt floors but increased diarrhea in children from households with nondirt floors, piped water, and indoor bathrooms. Zinc supplementation decreased diarrhea in children from households with dirt floors and whose mothers were more educated. Vitamin A supplementation increased cough with fever in children from less-crowded households that lacked indoor bathrooms and in children of less-educated mothers. Conclusions: Vitamin A increases diarrheal disease and respiratory tract infections in young children in periurban areas of Mexico City. Vitamin A and zinc have more heterogeneous effects in different subgroups of children.
Plasma Oxidative Status in Preterm Infants Receiving LCPUFA Supplementation: A Pilot Study
Nutrients, 2020
After birth, preterm infants are deficient in arachidonic acid (ARA), docosahexaenoic acid (DHA), and antioxidants, increasing their risk of oxidative stress-related pathologies. The principal aim was to evaluate if supplementation with long-chain polyunsaturated fatty acids (LCPUFAs) improves antioxidant defenses. In total, 21 preterm infants were supplemented with ARA and DHA in a 2:1 ratio (ARA:DHA-S) or with medium-chain triglycerides (MCT-S). Plasma n-3 and n-6 LCPUFAs were measured at birth, postnatal day 28, and 36 weeks of postmenstrual age (36 WPA) by gas chromatography–mass spectroscopy. Plasma antioxidants (glutathione (GSH), catalase, and thiols) and oxidative damage biomarkers (malondialdehyde (MDA), carbonyls) were analyzed at the same time points by spectrophotometry, and scores of antioxidant status (Antiox-S) and oxidative damage (Proxy-S) were calculated. At 36 WPA, linoleic acid (LA) and dihomo-γ-linolenic acid (DGLA) were decreased in ARA:DHA-S compared to the MC...
