Human Milk Oligosaccharides, Growth, and Body Composition in Very Preterm Infants.

Human milk oligosaccharides (HMOs) are bioactive factors that benefit neonatal health, but little is known about effects on growth in very preterm infants (<32 weeks' gestation). We aimed to quantify HMO concentrations in human milk fed to very preterm infants during the neonatal hospitalization and investigate associations of HMOs with infant size and body composition at term-equivalent age. In 82 human-milk-fed very preterm infants, we measured HMO concentrations at two time points.

Human Milk Oligosaccharides and Infant Neurodevelopment: A Narrative Review.

The objective of this narrative review was to synthesize the literature on human milk oligosaccharides (HMOs) and neurodevelopmental outcomes in human milk-fed infants. We conducted a scoping review of the literature indexed in PubMed reporting observational or interventional studies on HMO exposure in relation to psychometric measures in infants. Studies were characterized based on study design and definitions of HMO exposure and neurodevelopmental outcomes.

Preterm infant nutrition and growth with a human milk diet.

Human milk is the preferred enteral diet for preterm infants. It provides macronutrients, micronutrients, and bioactive factors that support physical growth and neurodevelopment. Challenges of the human milk diet include the variability in its composition and a need for fortification to mirror placental nutrient delivery and prevent extrauterine growth restriction.

Intravenous Fish Oil and Serum Fatty Acid Profiles in Pediatric Patients With Intestinal Failure-Associated Liver Disease.

Background: Intravenous fish oil (FO) treats pediatric intestinal failure-associated liver disease (IFALD). There are concerns that a lipid emulsion composed of ω-3 fatty acids will cause an essential fatty acid deficiency (EFAD). This study's objective was to quantify the risk for abnormal fatty acid concentrations in children treated with FO.

Two-Year Neurodevelopment and Growth Outcomes for Preterm Neonates Who Received Low-Dose Intravenous Soybean Oil.

Background: In some studies, the dose of intravenous soybean oil (SO) has been associated with a decreased incidence of intestinal failure-associated liver disease. The effect of lipid sparing on neurodevelopment (ND) and growth remains unknown. This study investigated the impact of SO dose on ND and growth over the first 2 years of age in preterm neonates.

Gonadal- and sex-chromosome-dependent sex differences in the circadian system.

Compelling reasons to study the role of sex in the circadian system include the higher rates of sleep disorders in women than in men and evidence that sex steroids modulate circadian control of locomotor activity. To address the issue of sex differences in the circadian system, we examined daily and circadian rhythms in wheel-running activity, electrical activity within the suprachiasmatic nucleus, and PER2::LUC-driven bioluminescence of gonadally-intact adult male and female C57BL/6J mice. We observed greater precision of activity onset in 12-hour light, 12-hour dark cycle for male mice, longer activity duration in 24 hours of constant darkness for female mice, and phase-delayed PER2::LUC bioluminescence rhythm in female pituitary and liver.

Expanding the Grading of Recommendations Assessment, Development, and Evaluation (Ex-GRADE) for Evidence-Based Clinical Recommendations: Validation Study.

Clinicians use general practice guidelines as a source of support for their intervention, but how much confidence should they place on these recommendations? How much confidence should patients place on these recommendations? Various instruments are available to assess the quality of evidence of research, such as the revised Wong scale (R-Wong) which examines the quality of research design, methodology and data analysis, and the revision of the assessment of multiple systematic reviews (R-AMSTAR), which examines the quality of systematic reviews.The Grading of Recommendation Assessment, Development, and Evaluation (GRADE) Working Group developed an instrument called the GRADE system in order to grade the quality of the evidence in studies and to evaluate the strength of recommendation of the intervention that is proposed in the published article. The GRADE looks at four factors to determine the quality of the evidence: study design, study quality, consistency, and directness.

Automatic transport ventilator versus bag valve in the EMS setting: a prospective, randomized trial.

Purpose: The primary objective of this study was to compare Emergency Medical Technicians-Paramedics (EMT-P) perceptions of the usefulness of an automatic transport ventilator (ATV) compared with bag valve (BV) ventilation for intubated patients.

Methods: Cardiopulmonary resuscitation or assisted ventilation patients were randomly assigned by day to the ATV or BV arm of the study. Questionnaires were completed by the EMT-Ps at the conclusion of each patient enrollment.

Effect of a social services intervention among 911 repeat users.

Objective: To determine whether emergency medical services (EMS) 911 frequent users would benefit from social services intervention.

Methods: The design was a descriptive prospective subject evaluation. All nonhomeless frequent EMS users (>3x in 1 month) were identified monthly from December 2 to May 3 and contacted by 2 social workers.

Emergency medical services screening of elderly falls in the home.

Objectives: Previous studies of injury prevention among the elderly have focused on care by community-based services for the elderly. The plan for this study was to determine whether emergency medical services (EMS) could be a valuable partner in an injury prevention program for the elderly. The purposes of the study were: 1) to determine whether it is feasible to gather injury prevention data prospectively, 2) to determine whether these data suggest the need for further intervention to aid the elderly, and 3) to determine whether retrospective chart data are comparable to prospectively gathered data for evaluating the elderly home environment.
