Article Synopsis
  • Iron deficiency (ID) is highly prevalent among patients with sleep/wake disorders, with 94% of the studied population affected and a strong family history component (43%).
  • A significant number of patients also presented with ADHD (46%) and ASD (45%), along with other sleep conditions like chronic insomnia (61%) and sleep-disordered breathing (50%).
  • The study suggests that a family history of ID increases the likelihood of sleep/wake disorders like restless legs syndrome (RLS) in patients with ADHD and ASD, emphasizing the need for better diagnostic methods combining blood tests and family history assessments.

Obstructive sleep apnea (OSA) is a disorder in which ventilation becomes disrupted due to a complete or partial upper airway obstruction Altered craniofacial morphology is one of the most important anatomical factors associated with obstructive sleep apnea (OSA). Studies have assessed craniofacial features in the non-syndromic pediatric population. The aim of this study was to analyze the orthodontic and facial characteristic of craniofacial syndromic children referred for polysomnography (PSG) and to assess the correlation with the apnea-hypopnea index (AHI).

Introduction: Motivated by challenges faced in outpatient sleep services for mental health and neurodevelopmental disorders (MHNDD) during the COVID-19 clinical shutdown, a pan-Canadian/international working group of clinicians and social scientists developed a concept for capturing challenging sleep and wake behaviours already at the referral stage in the community setting.

Methods: In a quality improvement/quality assurance (QIQA) project, a visual logic model was the framework for identifying the multiple causes and possible interventions for sleep disturbances. Intake forms informed clinicians about situational experiences, goals/concerns, in addition to the questions from the Sleep Disturbances Scale for Children (SDSC), the ADHD Rating Scale-IV and medication history.

Background: The rapid identification of deterioration in the pediatric population is complex, particularly in the emergency department (ED). A comprehensive multi-faceted Pediatric Early Warning System (PEWS) might maximize early recognition of clinical deterioration and provide a structured process for the reassessment and escalation of care. The objective of the study was to evaluate the implementation fidelity, effectiveness, and utility of a 5-component PEWS implemented in the ED of an urban public general hospital in British Columbia, Canada, and to guide provincial scale up.

Background: Assessments of pediatric obstructive sleep apnea (OSA) are underutilized across Canada due to a lack of resources. Polysomnography (PSG) measures OSA severity through the average number of apnea/hypopnea events per hour (AHI), but is resource intensive and requires a specialized sleep laboratory, which results in long waitlists and delays in OSA detection. Prompt diagnosis and treatment of OSA are crucial for children, as untreated OSA is linked to behavioral deficits, growth failure, and negative cardiovascular consequences.

The pediatric intensive care unit (ICU) is a complex environment, in which a multidisciplinary team of clinicians (registered nurses, respiratory therapists, and physicians) continually observe and evaluate patient information. Data are provided by multiple, and often physically separated sources, cognitive workload is high, and team communication can be challenging. Our aim is to combine information from multiple monitoring and therapeutic devices in a mobile application, the , to improve the efficiency of clinical decision-making, communication, and thereby patient safety.

Background: Despite the obvious challenges faced by families caring for children on home ventilation, there is surprisingly little research into the details of their daily lives. In particular, little is known about the quality of life of the child and caregiver plus the associated social and economic burdens of care.

Methods: We prospectively studied 90 families enrolled in a paediatric home ventilation service in British Columbia.

Obstructive sleep apnea (OSA) disrupts normal ventilation during sleep and can lead to serious health problems in children if left untreated. Polysomnography, the gold standard for OSA diagnosis, is resource intensive and requires a specialized laboratory. Thus, we proposed to use the Phone Oximeter™, a portable device integrating pulse oximetry with a smartphone, to detect OSA events.

Individuals with sleep disordered breathing (SDB) can experience changes in automatic cardiac regulation as a result of frequent sleep fragmentation and disturbance in normal respiration and oxygenation that accompany most apnea/hypopnea events. In adults, these changes are reflected in enhanced sympathetic and reduced parasympathetic activity. In this study, we examined the autonomic cardiac regulation in children with and without SDB, through spectral and detrended fluctuation analysis (DFA) of pulse rate variability (PRV).

Congenital central hypoventilation syndrome (CCHS) is a rare neurocristopathy with severe central hypoventilation. CCHS results from a mutation in the paired-like homeobox 2B gene (PHOX2B). In addition to hypoventilation, patients with CCHS display a wide array of autonomic nervous system abnormalities, including decreased heart rate variability and abrupt sinus pauses, esophageal dysmotility, abnormal pupillary light response, and temperature dysregulation, to name a few.
