GDF15 Knockout Does Not Substantially Impact Perinatal Body Weight or Neonatal Outcomes in Mice.

Growth differentiation factor-15 (GDF15) increases in circulation during pregnancy and has been implicated in food intake, weight loss, complications of pregnancy, and metabolic illness. We used a Gdf15 knockout mouse model (Gdf15-/-) to assess the role of GDF15 in body weight regulation and food intake during pregnancy. We found that Gdf15-/- dams consumed a similar amount of food and gained comparable weight during the course of pregnancy compared with Gdf15+/+ dams.

Pregnancy-specific dietary guidelines for Americans are not met: Findings from a pilot study.

Objective: To assess maternal dietary intake during pregnancy and adherence to the 2020-2025 pregnancy-specific Dietary Guidelines for Americans (DGA).

Methods: This was a retrospective observational study. The study population consisted of women who gave birth to term infants (>37 weeks of gestation).

The preterm human milk microbiota fluctuates by postpartum week and is characterized by gestational age and maternal BMI.

Despite a growing recognition that the type of nutrition received by preterm infants influences their intestinal microbiome and health outcomes, the microbiota of mother's own milk (MOM), pasteurized donor human milk (PDHM), and infant formula remain poorly characterized. In our study, we found that the structure of microbial communities, bacterial diversity, and relative abundances of specific genera were significantly different between MOM, PDHM, and formula. Additionally, our results suggest that the microbiota of MOM changes as a function of time and maternal factors.

Gestational Early-Time Restricted Feeding Results in Sex-Specific Glucose Intolerance in Adult Male Mice.

The timing of food intake is a novel dietary component that impacts health. Time-restricted feeding (TRF), a form of intermittent fasting, manipulates food timing. The timing of eating may be an important factor to consider during critical periods, such as pregnancy.

Women Who Give Birth Preterm Do Not Meet Dietary Guidelines During Pregnancy.

Purpose: To evaluate maternal dietary intake during pregnancy compared with the 2015-2020 and 2020-2025 Dietary Guidelines for Americans (DGA).

Study Design And Methods: A retrospective observational study design was used. The cohort included women who gave birth to preterm infants between 25 1/7 weeks and 33 6/7 weeks of gestation.

Short Term Changes in Dietary Fat Content and Metformin Treatment During Lactation Impact Milk Composition and Mammary Gland Morphology.

Maternal health and diet can have important consequences for offspring nutrition and metabolic health. During lactation, signals are communicated from the mother to the infant through milk via macronutrients, hormones, and bioactive molecules. In this study we designed experiments to probe the mother-milk-infant triad in the condition of normal maternal health and upon exposure to high fat diet (HFD) with or without concurrent metformin exposure.

A peer evaluation training results in high-quality feedback, as measured over time in nutritional sciences graduate students.

Peer evaluation skills are not typically taught to students, yet they are expected to provide high-quality feedback to their peers. Gameful learning, a pedagogy supporting student-driven learning, can further reinforce the development of peer evaluation skills, if students are motivated to improve upon them. To better understand the effects of a peer evaluation training on the quality of student-generated peer evaluations, we scored peer evaluations from two cohorts taking a graduate-level nutritional sciences class using gameful learning pedagogy.
