Objective: Studies of birth patterns in anorexia nervosa have shown relative increases between March and August, while studies in Bulimia Nervosa (BN) have been negative. Since there are no studies using representative, nonclinical samples, we looked for seasonal birth patterns in women with BN and in those who ever endorsed bingeing or purging.

Method: A national, representative sample of 3,006 adult women completed structured telephone interviews including screenings for bulimia nervosa (BN) and questions about month, date, and year of birth. Season of birth was calculated using traditional definitions. Differences across season of birth between subjects with (n = 85) and without BN (n = 2,898), those with (n = 749) and without bingeing (n = 2,229), and those with (n = 267) and without any purging (n = 2,715) were compared using chi-square analyses.

Results: There were significant differences across season of birth between subjects: (1) with and without BN (p = 0.033); (2) with and without bingeing (p = 0.034), and; (3) with and without purging (p = 0.001). Fall had the highest relative number of births for all categories, while spring had the lowest.

Discussion: In a national representative study of nontreatment seeking subjects significant differences in season of birth were found for subjects with lifetime histories of BN, binge eating and purging. © 2011 by Wiley Periodicals, Inc. (Int J Eat Disord 2012).

Background: Preterm infants (PIs) are more susceptible to neurodevelopmental impairment compared with term newborns. Adequate postnatal growth has been associated with improved neurocognitive outcomes; therefore, optimization of nutrition may positively impact the neurodevelopment of PIs.

Objective: This study focused on macronutrient parenteral nutrition (PN) intake during the Neonatal Intensive Care Unit stay and their associations with neurodevelopmental outcomes in PIs in the first two years of life.

The rapid growth of unconventional natural gas development (UNGD), also known as hydraulic fracturing, has raised concerns of potential exposures to hazardous chemicals. Few studies have examined the risk of childhood cancer from exposure to UNGD. A case-control study included 498 children diagnosed with leukemia, lymphoma, central nervous system neoplasms, and malignant bone tumors during the period 2010-2019 identified through the Pennsylvania Cancer Registry.

Background: The evolving infant gut microbiome influences host immune development and later health outcomes. Early antibiotic exposure could impact microbiome development and contribute to poor outcomes. Here, we use a prospective longitudinal birth cohort of n = 323 healthy term African American children to determine the association between antibiotic exposure and the gut microbiome through shotgun metagenomics sequencing as well as bile acid profiles through liquid chromatography-mass spectrometry.

Risk Factors for Developmental Dysplasia of the Hip Before 3 Months of Age: A Meta-Analysis.

JAMA Netw Open

January 2025

Interdisciplinary Orthopaedics, Department of Orthopaedic Surgery, Aalborg University Hospital, Aalborg, Denmark.

Importance: Two meta-analyses published in 2012 found breech presentation, family history of developmental dysplasia of the hip (DDH), female sex, and primiparity to increase the risk of DDH. However, the DDH definition, reference tests, and the age of the examined children varied considerably, complicating the translation of those findings to current screening guidelines.

Objective: To evaluate the association of previously proposed risk factors with the risk of sonography-verified DDH.

Objective: To establish a prediction nomogram for early prediction of neonatal acute respiratory distress syndrome (NARDS).

Methods: This is a retrospective cross-sectional study conducted between January 2021 and December 2023. Clinical characteristics and laboratory results of cases with neonatal pneumonia were compared in terms of presence of NARDS diagnosis based on the Montreux Definition.
