Neonatal multimorbidity and the phenotype of premature aging in preterm infants.

Multimorbidity is the co-occurrence of multiple chronic health problems, associated with aging, frailty, and poor functioning. Children born preterm experience more multimorbid conditions in early life compared to term-born peers. Though neonatal multimorbidity is linked to poor health-related quality of life, functional outcomes, and peer group participation, gaps in our theoretical understanding and conceptualization remain.

Epigenetic age acceleration in follicular fluid and markers of ovarian response among women undergoing IVF.

Study Question: Are markers of epigenetic age acceleration in follicular fluid associated with outcomes of ovarian stimulation?

Summary Answer: Increased epigenetic age acceleration of follicular fluid using the Horvath clock, but not other epigenetic clocks (GrimAge and Granulosa Cell), was associated with lower peak estradiol levels and decreased number of total and mature oocytes.

What Is Known Already: In granulosa cells, there are inconsistent findings between epigenetic age acceleration and ovarian response outcomes.

Study Design, Size, Duration: Our study included 61 women undergoing IVF at an academic fertility clinic in the New England area who were part of the Environment and Reproductive Health Study (2006-2016).

The Work-life Check-ins randomized controlled trial: A leader-based adaptive, semi-structured burnout intervention in primary care clinics.

Background: Burnout in primary care undermines worker well-being and patient care. Many factors contribute to burnout, including high workloads, emotional stress, and unsupportive supervisors. Formative evidence suggests that burnout might be reduced if clinic leaders hold quarterly and brief (∼30 min) one-on-one check-ins with team members to acknowledge and address work-life stressors (e.

Placental PFAS concentrations are associated with perturbations of placental DNA methylation at loci with important roles on cardiometabolic health.

The placenta is crucial for fetal development, is affected by PFAS toxicity, and evidence is accumulating that gestational PFAS perturb the epigenetic activity of the placenta. Gestational PFAS exposure is can adversely affect offspring, yet individual and cumulative impacts of PFAS on the placental epigenome remain underexplored. Here, we conducted an epigenome-wide association study (EWAS) to examine the relationships between placental PFAS levels and DNA methylation in a cohort of mother-infant dyads in Arkansas.
