Alcohol is a known teratogen and prenatal alcohol exposure remains a major ongoing public health concern. Fetal alcohol spectrum disorder has become the diagnosis for describing individuals who have been affected by prenatal alcohol exposure. In this Viewpoint, we raise major concerns about its continued use as a diagnostic term in how it perpetuates a misleading and outdated narrative about child development and maternal health.

Background: Oxytocin is a neuropeptide hormone that plays a key role in social behavior, stress regulation, and mental health. Synthetic oxytocin administration is a common obstetrical practice, and importantly, previous research has suggested that intrapartum exposure may increase the risk of neurodevelopmental disorders, such as autism spectrum disorder.

Objective: This study aimed to examine the association between synthetic oxytocin exposure during labor and autism spectrum disorder diagnosis in the child.

Background: Prenatal antibiotic exposure induces changes in the maternal microbiome, which could influence the development of the infant's microbiome-gut-brain axis.

Objectives: We assessed whether prenatal antibiotic exposure is associated with an increased risk of autism spectrum disorder (ASD) in offspring born at term.

Methods: This population-based retrospective cohort study included everyone who delivered a live singleton-term infant in British Columbia, Canada between April 2000 and December 2014.

Objectives: Antibiotics are commonly administered during labor and delivery, and research has suggested that fetal exposure to antibiotics can increase risk for autism spectrum disorder (ASD). We assessed whether antibiotic exposure during labor and delivery increased the risk of ASD in the offspring.

Methods: This retrospective cohort study included everyone who delivered a live singleton-term infant in British Columbia, Canada, between April 1, 2000, and December 31, 2014.

Background: Autism spectrum disorder (ASD) incidence has increased in past decades. ASD etiology remains inconclusive, but research suggests genetic, epigenetic, and environmental contributing factors and likely prenatal origins. Few studies have examined modifiable environmental risk factors for ASD, and far fewer have examined protective exposures.

Objectives: Mandatory audiological testing before autism spectrum disorder (ASD) assessment is common practice. Hearing impairment (HI) in the general paediatric population is estimated at 3%; however, hearing impairment prevalence among children with ASD is poorly established. Our objective was to determine which children referred for ASD assessment require preliminary audiological assessment.

Importance: Evidence from studies investigating the association of epidural analgesia use during labor and delivery with risk of autism spectrum disorder (ASD) in offspring is conflicting.

Objective: To assess the association of maternal use of epidural analgesia during labor and delivery with ASD in offspring using a large population-based data set with clinical data on ASD case status.

Design, Setting, And Participants: This population-based retrospective cohort study included term singleton children born in British Columbia, Canada, between April 1, 2000, and December 31, 2014.

Baclofen is a medication used for tone management in cerebral palsy. Although it acts mainly at the spinal cord level, it can cause central nervous system adverse reactions at higher doses. Baclofen is mainly eliminated by renal excretion and there have been reports on adverse events when used in adults with renal impairment; however, there are no consensus guidelines as to the dose adjustments required due to renal impairment.

Article Synopsis
  • Administrative data has been commonly used in research to identify cases of Autism Spectrum Disorder (ASD), but prior studies lacked robust clinical validation.
  • A study involving nearly 8,670 children in British Columbia tested the accuracy of 11 algorithms for determining ASD status using linked health data, with clinical assessments as the gold standard.
  • The findings revealed that while some algorithms had high positive predictive values, they were still inadequate for reliably distinguishing ASD from other developmental disorders, highlighting a need for better validation studies in this area.

Importance: The etiology of autism spectrum disorder (ASD) is poorly understood, but prior studies suggest associations with airborne pollutants.

Objective: To evaluate the association between prenatal exposures to airborne pollutants and ASD in a large population-based cohort.

Design, Setting, And Participants: This population-based cohort encompassed nearly all births in Metro Vancouver, British Columbia, Canada, from 2004 through 2009, with follow-up through 2014.

Context: Infant crying can cause parental distress, and colic is associated with low maternal self-efficacy and heightened risk for depression. Breastfeeding is recognized as an effective method of calming infants, but the relationship of colic and the use of breastfeeding to remedy infant crying have not been tested for any effects on breastfeeding duration.

Objective: To evaluate the effects of infant colic (colic analysis) and breastfeeding as a method of infant calming (calming analysis) on breastfeeding duration.

Purpose: To examine pediatric faculty members' attitudes about part-time faculty positions and policies to support part-time faculty.

Method: In 2001, an anonymous 26-item questionnaire assessing attitudes about part-time faculty was mailed to all 441 faculty members of Cincinnati Children's Hospital Medical Center. Multivariable analyses were used to determine faculty characteristics associated with specific attitudes, and qualitative methods were used to analyze responses to an open-ended item assessing beliefs about facilitating part-time careers.

Children and adults with Rubinstein-Taybi Syndrome have specific medical conditions that occur with greater frequency than the general population. Based on the available information from the literature and clinical experience, recommendations for specific surveillance and interventions are made to guide those clinicians caring for individuals with Rubinstein-Taybi Syndrome. This is a first attempt at medical guidelines for individuals with RTS in the United States.
