Influence of maternal α-lipoic acid supplementation in Sprague Dawley rats on maternal and fetal metabolic health in pregnancies complicated by obesity.

The objective of this study was to investigate the influence of α-lipoic acid (LA; R enantiomer) supplementation on maternal and fetal metabolic health in pregnancies complicated by maternal obesity. Forty female Sprague-Dawley rats were randomized to one of 4 treatment groups (n=10/group) throughout prepregnancy (3 weeks) and gestation (20 days): (1) a low calorie control (CON); (2) a high calorie obesity-inducing diet (HC); (3) the HC diet with 0.25% LA (HC+LA) or; (4) the HC diet pair-fed to match the caloric intake of the HC+LA group (HC+PF).

Glucose intolerance as a consequence of hematopoietic stem cell dysfunction in offspring of obese mice.

Objective: Maternal obesity is increasingly common and negatively impacts offspring health. Children of mothers with obesity are at higher risk of developing diseases linked to hematopoietic system abnormalities and metabolism such as type 2 diabetes. Interestingly, disease risks are often dependent on the offspring's sex, suggesting sex-specific reprogramming effect of maternal obesity on offspring hematopoietic stem and progenitor cell (HSPC) function.

A simple step to improve fat and energy delivery of human milk delivered via bottle-feeding pump: An experimental study.

Background: Enteral feeding pump systems deliver decreased amounts of macronutrients in human milk to neonates. This study determined the macronutrient loss associated with a bottle-feeding pump system and the effect of manually mixing the human milk during extended feeds.

Methods: Macronutrient content from samples of donor human milk was analyzed after simulated extended feeds with a bottle-feeding pump system, using a human milk analyzer.

Increased allergic inflammation and decreased lung insulin sensitivity in offspring of obese allergic mothers.

Epidemiological studies demonstrate that maternal obesity and maternal allergy are major risk factors for asthma in offspring. However, the impact of maternal allergy and obesity on offspring lung insulin signaling and allergen responsiveness is not known. To evaluate this, allergic and nonallergic female mice were fed a high-fat diet or low-fat diet from 7 wk before pregnancy until weaning.

Efficacy of supplemental oxygen in reducing the need for laser or intravitreal bevacizumab in preterm infants with stage 2 retinopathy of prematurity.

Background: Retinopathy of prematurity (ROP) is a disease that affects preterm infants born younger than 30 weeks of gestation. The pathophysiology of ROP involves an initial vaso-obliterative phase followed by vaso-proliferative phase that leads to disease progression. The use of supplemental oxygen during the vaso-proliferative phase of ROP has been associated with reduced disease progression, but how this impacts the need for ROP treatment is unclear.
