Article Synopsis
  • The study examined the impact of the COVID-19 pandemic on mothers with young children, focusing on factors like anxiety, stress, and financial issues before and during the pandemic.
  • Mothers reported significant increases in anxiety (9.4%), perceived stress (13.3%), and financial stress (41.7%) during the pandemic, with family routines being the most affected area (72.4%).
  • Interestingly, prepandemic psychosocial stress did not predict pandemic impact, indicating that new stresses arose during the pandemic that compounded existing inequalities rather than simply amplifying prior distress.

Article Synopsis
  • Maternal childhood adversity is linked to negative health outcomes for both mothers and their offspring, including potential effects on infant epigenetics.
  • Research investigates how maternal restless sleep during pregnancy affects the relationship between childhood adversity and infant epigenetic age, involving 332 mother-infant pairs.
  • Findings suggest that infants whose mothers experienced both childhood adversity and restless sleep show signs of accelerated epigenetic aging, indicating that these factors may influence the infant's epigenome.

Purpose: Human immunodeficiency virus (HIV) burden among Florida adolescents and young adults (AYA, aged 13-24 years), particularly in Tampa Bay, is among the highest in the nation. We sought to determine the association between zip code-level test site accessibility and AYA HIV burden, compare this association with adult (aged 25-44 years) HIV burden, and identify local AYA HIV testing deserts. We further aimed to identify the association between test site accessibility and population-level markers of social disadvantage.

Article Synopsis
  • This study developed an epigenetic clock for newborns using human umbilical vein endothelial cells (HUVEC) from a diverse population, addressing the lack of similar tools focused on infants.
  • The research found a strong correlation (r = 0.85) between epigenetic gestational age and clinical gestational age in newborns, surpassing previous correlations seen in adult and predominantly European ancestry samples.
  • Results showed variations in epigenetic gestational age acceleration based on birth weight and NICU admission status, with differences noted among self-identified racial and ethnic groups, emphasizing the need for tailored epigenetic clocks.

Article Synopsis
  • The Coronavirus Impact Scale was developed to assess how the COVID-19 pandemic has affected families with children and adolescents, focusing on various demographics and settings.
  • A study involving 572 caregivers revealed that single immigrant Latinx mothers experienced the most significant challenges, particularly related to food access and financial issues, while healthcare access was more impacted among outpatient and inpatient individuals.
  • The scale showed strong internal consistency and was linked to higher levels of caregiver anxiety and stress for both caregivers and children, making it a valuable tool for measuring pandemic effects in different populations.

Article Synopsis
  • The study investigates how financial stress during pregnancy impacts the relationship between maternal adverse childhood experiences (ACEs) and birth outcomes such as gestational age and birth weight.
  • Data was collected from 531 pregnant women in Florida and North Carolina, analyzing correlations between self-reported childhood adversity, financial stress, and medical records of birth outcomes.
  • Results indicate that higher maternal ACE scores lead to earlier gestational ages and lower birth weights due to increased financial stress, while there was no significant link to NICU admissions, highlighting areas for potential intervention for expectant mothers.

Introduction: Recent calls to action have urged graduate medical education leaders to develop health equity-focused curricula (HEFC) to redouble efforts to promote pediatric HE and address racism. Despite this call, examples of HEFC for pediatric residents are lacking. Such curricula could catalyze educational innovations to address training gaps.

Training experiences where residents provide Spanish-language concordant care (SLCC) have not been widely described despite their increasing need and prevalence in graduate medical education. In this qualitative study, we enrolled nonnative Spanish-speaking residents (n = 21) within SLCC training clinics from 3 geographically unique programs. Participants completed semistructured interviews focused on their overall SLCC training experience.

Newborn screening using dried plasma spots offers preanalytical advantages over conventional cards for plasma-associated targets of interest. Herein we present dried plasma spot-based methods for measuring metabolites using a 250+ compound liquid chromatography tandem mass spectrometry library. Quality assurance reduced this library to 134, and from these, 30 compounds determined the normal newborn reference ranges.

During the COVID-19 pandemic, antivaccination social media accounts are proliferating online, threatening to further escalate vaccine hesitancy related to the COVID-19 vaccine. This commentary seeks to alert and encourage the health care provider community, including health care professionals and academic organizations, to engage in social media to counter the mounting vaccine-related . To validate our recommendation for engagement, the authors describe preliminary findings using a mixed methods approach of quantitative Twitter-based ranking algorithms of networks and users with qualitative content analysis of 1 million tweets related to COVID-19 vaccine conversations.

Purpose: Subjective social status (SSS), perceived social standing relative to others, has been associated with health status, independent of objective socioeconomic status (SES). Few studies have examined the relationship of prenatal maternal SSS with birth outcomes. We evaluated the association of SSS in pregnancy with low birth weight (LBW) and high birth weight (HBW).

To describe prevalence of healthy lifestyle behaviors (HLBs) between two school-age cohorts of racial-ethnically diverse children. Using two Early Childhood Longitudinal Study cohorts (ECLS-K 1999 and 2010), we compared percentage change in HLBs (sleep, physical activity, screen time, and family meals) by child weight groups and within racial-ethnic groups. Weight groups of interest included healthy weight (HW; BMI 5th-84th percentile), overweight (OW; ≥ 85th-94th), obese (OB; ≥ 95th-99th percentile), and severely obese (SO; ≥ 99th percentile).

High body mass index (BMI) is associated with relapse of certain adult cancers, but limited knowledge exists on its association with pediatric leukemia relapse. We evaluated the association between overweight/obesity (BMI ≥ 85 percentile) at pediatric leukemia diagnosis and relapse or mortality. A meta-analysis combining our findings with those of previous studies was also performed.

The development of new graduate medical education programmes provides both opportunities and challenges. Efforts to address physician workforce shortages as well as a realisation that curricula need to be updated to adjust to our rapidly changing healthcare environment have resulted in more educators considering the "how to" and "what's new" of programme development. Understanding the Next Accreditation System, an accreditation system introduced by the Accreditation Council of Graduate Medical Education in 2012, is critical to the success of new as well as existing residency and fellowship programmes.
