RESUMEN
BACKGROUND: Increasing evidence suggests an association between childhood obstructive sleep apnea (OSA) and metabolic syndrome, with more research available on the potential impacts of positive airway pressure (PAP) on metabolic markers in children. The purpose of this systematic review is to provide a systematic synthesis of the evidence on the effect of PAP use on metabolic markers in children with OSA. METHODS: A search strategy with terms for "OSA" and metabolic markers in pediatrics was run to systematically assess 5 databases until August 26, 2022. Two reviewers independently screened eligible articles, extracted data, and conducted quality appraisal. Meta-analysis was done using random-effects models. Body mass index (BMI), glycemic, lipid, cardiovascular, and other metabolic and inflammatory markers were reported. RESULTS: Sixteen studies (N = 1,213) were included, 15 observational studies and 1 randomized controlled trial (RCT); most reported outcomes in children with obesity. Meta-analysis of 4 studies found no changes in BMI at median average follow-up of 12 months after PAP initiation. A reduction in heart rate and blood pressure parameters was demonstrated in several studies in children with OSA with and without obesity at a median average follow-up of 4.9 months after PAP initiation. Research in echocardiographic outcomes is limited, including one RCT in children with Down syndrome and OSA showing no changes in heart rate variability parameters. Evidence of improvements in glycemic and/or lipid control, liver enzymes, and inflammatory markers with PAP therapy is even more limited and of limited clinical importance. Risk of bias was moderate to critical and outcome evidence very low. CONCLUSIONS: Although evidence on effects of PAP on metabolic markers in children with OSA is encouraging, available literature is limited. Longitudinal studies are still required to further assess the long-term influence of PAP on metabolic and inflammatory markers, particularly in children with obesity.

STUDY OBJECTIVES: The aim of this study was to measure changes in adherence to noninvasive ventilation (NIV) in children during the first year of the COVID-19 pandemic. METHODS: Retrospective chart review of children (0-18 years) using home NIV through the Stollery's Pediatric NIV program in Edmonton, Canada during March 2019 to March 2021. Demographics, clinical characteristics, and adherence information from machine downloads were collected prior to and during the first year of the COVID-19 pandemic. Paired t tests and Chi-square compared adherence prepandemic and during pandemic and repeated analysis of variance tests compared adherence pre- and 0-6 and 6-12 months during pandemic. RESULTS: Eighty-two children met inclusion criteria (62% male; age 8.6 ± 4.6 years). Overall, there were no changes in NIV adherence during pandemic (average NIV minutes pre- and during pandemic of 390 ± 219 and 405 ± 300 minutes, respectively). When separated into increased vs decreased adherence groups, adherence differences pre- compared to during pandemic became significant, with no differences across demographic/clinical variables or prepandemic adherence. There were no changes in NIV adherence during the initial 6 months of pandemic compared to prepandemic, but NIV use significantly increased by 9-57 minutes during the following 6-12 months. Bilevel positive airway users had longer NIV use than continuous positive airway pressure users at all time points, with an overall increasing trend over time. CONCLUSIONS: Despite the significant life disruption created by COVID-19 and changes to virtual care, children using home NIV maintained adequate adherence. Qualitative research is needed to understand the nuances of using NIV during the pandemic and potential advantages of virtual care for support of these children and families.

Context: Children with Down syndrome are at risk for obstructive sleep apnea, which may not be resolved by adenotonsillecotmy, as well as other respiratory disorders that may impact breathing during sleep. Long-term non-invasive ventilation, including continuous and bilevel positive airway pressure delivery, is an alternate treatment strategy. Objective: To assess the use and outcomes of long-term non-invasive ventilation in children with Down syndrome including comparison to other children using long-term non-invasive ventilation. Data Sources: The search strategy for the scoping review used Medical Subject Headings (MeSH) and free-text terms for "child" and "non-invasive ventilation." MEDLINE (Ovid), Embase (Ovid), CINAHL (Ebsco), Cochrane Library (Wiley), and PubMed databases were searched (1990-2021). Study Selection: The scoping review results were searched to identify studies including data on at least three children with Down Syndrome using long-term non-invasive ventilation. Data Extraction: Study characteristics, subject characteristics, technology type, and outcome measurements were extracted. Results: A total of 28 articles included 543 children with Down syndrome using long-term non-invasive ventilation. Children with Down syndrome accounted for 18% of children using long-term non-invasive ventilation. Data on efficacy, feasibility, and adherence in children with Down syndrome are comparable to other children. Children with Down syndrome may have greater difficulty initiating long-term non-invasive ventilation, longer time to establish use, and a higher rate of inability to establish use. Outcome data is limited but suggest favorable impact on cardiac function and attention. Limitations: Articles related to long-term non-invasive ventilation use in adolescents and young adults may have been excluded. Conclusions: Children with Down syndrome make up a significant portion of the population of children using long-term non-invasive ventilation. While there is more limited data available with respect to the use and outcomes for children with Down syndrome compared to the other children, long-term non-invasive ventilation is an effective and well-tolerated therapy with no clear differences in the use or outcomes for children with Down syndrome. Additional work is needed to understand potential challenges around establishing long-term non-invasive ventilation use in children with Down syndrome.

RESUMEN
STUDY OBJECTIVES: The gold standard test for diagnosis of sleep related breathing disorders (SRBD) in children is diagnostic polysomnography (PSG). This is often followed by a titration PSG to identify optimal non-invasive ventilation (NIV) pressures. Access to pediatric PSG is limited, resulting in delays to diagnosis and initiation of treatment. Split-night PSGs (snPSG) combine a diagnostic and titration PSG into a single night study. Although described in adults, the pediatric literature on this topic is sparse. The objective of this study was to describe a large cohort of children who utilized snPSG to diagnose SRBD and initiate NIV. METHODS: This multi-center study analyzed clinical and PSG data from children with SRBD who had initiated NIV following a snPSG. Data from diagnostic and titration portions of the snPSG were analyzed separately. RESULTS: The study included 165 children who initiated NIV following a snPSG. The majority of children (61.8%) were initiated on NIV for upper airway obstruction. The population included children with medical complexity, including those with central nervous system disorders (17.0%), musculoskeletal/neuromuscular disorders (12.1%), and cardiac disorders (1.2%). Moderate to severe SRBD was present in 87.2% of children with a median apnea-hypopnea index (AHI) of 16.6 events/hour (IQR: 8.2, 38.2). The median AHI was reduced on treatment to 7.6 events/hour (IQR: 3.3, 17.1), with fewer subjects meeting criteria for severe SRBD. CONCLUSIONS: snPSG is technically feasible in children, facilitating the diagnosis of SRBD and initiation of NIV, even in those with high medical complexity.

DESIGN AND METHODS: This study used a retrospective design and involved reviewing the charts of infants and children enrolled in the noninvasive ventilation (NIV) program at a quaternary pediatric hospital located in Western Canada in 2017. Demographic and clinical variables were collected, along with variables related to adherence to NIV therapy. For data storage and analysis purposes, a comprehensive database was created. Descriptive statistics were used to analyze and better understand patterns within the data. RESULTS: Findings included a comprehensive description of the population of infants and children enrolled in this NIV program in 2017, including demographic and clinical variables as well as follow-up and adherence data. This study identified that the NIV program at this pediatric center has unique characteristics which provide an exciting opportunity for further research into the population that requires NIV support. PRACTICE IMPLICATIONS: This study presents new knowledge, gathered by examining the clinical characteristics of a pediatric population that requires NIV, which can be used to inform practice, support NIV program planning, and health resource allocation, as well as suggest directions for future research on pediatric NIV therapy.

BACKGROUND: Noninvasive ventilation (NIV) is a first-line therapy for sleep-related breathing disorders and chronic respiratory insufficiency. Evidence about predictors that may impact long-term NIV outcomes, however, is scarce. The aim of this study is to determine demographic, clinical, and technology-related predictors of long-term NIV outcomes. METHODS: A 10-year multicentred retrospective review of children started on long-term continuous or bilevel positive airway pressure (CPAP or BPAP) in Alberta. Demographic, technology-related, and longitudinal clinical data were collected. Long-term outcomes examined included ongoing NIV use, discontinuation due to improvement in underlying conditions, switch to invasive mechanical ventilation (IMV) or death, patient/family therapy declination, transfer of services, and hospital admissions. RESULTS: A total of 622 children were included. Both younger age and CPAP use predicted higher likelihood for NIV discontinuation due to improvement in underlying conditions (p < .05 and p < .01). Children with upper airway disorders or bronchopulmonary dysplasia were less likely to continue NIV (p < .05), while presence of central nervous system disorders had a higher likelihood of hospitalizations (p < .01). The presence of obesity/metabolic syndrome and early NIV-associated complications predicted higher risk for NIV declination (p < .05). Children with more comorbidities or use of additional therapies required more hospitalizations (p < .05 and p < .01) and the latter also predicted higher risk for being switched to IMV or death (p < .001). CONCLUSIONS: Demographic, clinical data, and NIV type impact long-term NIV outcomes and need to be considered during initial discussions about therapy expectations with families. Knowledge of factors that may impact long-term NIV outcomes might help to better monitor at-risk patients and minimize adverse outcomes.

The selection of the mask interface for non-invasive ventilation (NIV) is recognized to be an essential part for therapy success. While nasal masks are the first recommended option in children and adults, there are indications for other mask types such as intolerance or complications from nasal masks. Evidence comparing performance, adherence and complication risk among mask interfaces in pediatrics is, however, scarce and information is often extrapolated from adult studies. Given this gap in knowledge and the lack of guidelines on NIV initiation in children, mask selection often relies on the clinicians' knowledge and expertise. Careful mask selection, a well-fitting headgear and time investment for mask desensitization are some important recommendations for adequate mask adaptation in children. Frequent mask-related complications include nasal symptoms, unintentional leak, mask displacement, skin injury, and midface hypoplasia. Close monitoring and a pro-active approach may help to minimize complications and promote the optimal use of home NIV.

OBJECTIVES: To describe longitudinal trends in long-term non-invasive ventilation (NIV) use in children including changes in clinical characteristics, NIV technology, and outcomes. METHODS: This was a multicenter retrospective cohort of all children started on long-term NIV from 2005 to 2014. All children 0 to 18 years who used NIV continuously for at least 3 months were included. Measures and main outcomes were: 1) Number of children starting NIV; 2) primary medical condition; 3) medical complexity defined by number of comorbidities, surgeries and additional technologies; 4) severity of sleep disordered breathing measured by diagnostic polysomnography; 5) NIV technology and use; 6) reasons for NIV discontinuation including mortality. Data were divided into equal time periods for analysis. RESULTS: A total of 622 children were included in the study. Median age at NIV initiation was 7.8 years (range 0-18 years). NIV incidence and prevalence increased five and three-fold over the 10-year period. More children with neurological and cardio-respiratory conditions started NIV over time, from 13% (95%CI, 8%-20%) and 6% (95%CI, 3%-10%) respectively in 2005-2008 to 23% (95%CI, 18%-28%) and 9% (95%CI, 6%-14%, p = 0.008) in 2011-2014. Medical complexity and severity of the sleep-disordered breathing did not change over time. Overall, survival was 95%; mortality rates, however, rose from 3.4 cases (95% CI, 0.5-24.3) to 142.1 (95% CI 80.7-250.3, p<0.001) per 1000 children-years between 2005-2008 and 2011-2014. Mortality rates differed by diagnostic category, with higher rates in children with neurological and cardio-respiratory conditions. CONCLUSIONS: As demonstrated in other centers, there was a significant increase in NIV prevalence and incidence rate. There was no increase in medical complexity or severity of the breathing abnormalities of children receiving long-term NIV over time. The mortality rate increased over time, maybe attributable to increased use of NIV for children with neurological and cardio-respiratory conditions.

Long-term non-invasive ventilation (NIV) is a common modality of breathing support used for a range of sleep and respiratory disorders. The aim of this scoping review was to provide a summary of the literature relevant to long-term NIV use in children. We used systematic methodology to identify 11,581 studies with final inclusion of 289. We identified 76 terms referring to NIV; the most common term was NIV (22%). Study design characteristics were most often single center (84%), observational (63%), and retrospective (54%). NIV use was reported for 73 medical conditions with obstructive sleep apnea and spinal muscular atrophy as the most common conditions. Descriptive data, including NIV incidence (61%) and patient characteristics (51%), were most commonly reported. Outcomes from sleep studies were reported in 27% of studies followed by outcomes on reduction in respiratory morbidity in 19%. Adverse events and adherence were reported in 20% and 26% of articles respectively. Authors reported positive conclusions for 73% of articles. Long-term use of NIV has been documented in a large variety of pediatric patient groups with studies of lower methodological quality. While there are considerable data for the most common conditions, there are fewer data to support NIV use for many additional conditions.

INTRODUCTION: Non-invasive ventilation (NIV) in children has become an increasingly common modality of breathing support where pressure support is delivered through a mask interface or less commonly through other non-invasive interfaces. At this time, NIV is considered a first-line option for ventilatory support of chronic respiratory insufficiency associated with a range of respiratory and sleep disorders. Previous reviews on the effectiveness, complications and adherence to NIV treatment have lacked systematic methods. The purpose of this scoping review is to provide an overview of the evidence for the use of long-term NIV in children. METHODS AND ANALYSIS: We will use previously established scoping methodology. Ten electronic databases will be searched to identify studies in children using NIV for longer than 3 months outside an intensive care setting. Grey literature search will include conference proceedings, thesis and dissertations, unpublished trials, reports from regulatory agencies and manufacturers. Two reviewers will independently screen titles and abstracts for inclusion, followed by full-text screening of potentially relevant articles to determine final inclusion. Data synthesis will be performed at three levels: (1) an analysis of the number, publication type, publication year, and country of publication of the studies; (2) a summary of the study designs, outcomes measures used; (3) a thematic analysis of included studies by subgroups. ETHICS AND DISSEMINATION: This study will provide a wide and rigorous overview of the evidence on the use of long-term NIV in children and provide critical information for healthcare professionals and policymakers to better care for this group of children. We will disseminate our findings through conference proceedings and publications, and evaluate the results for further systematic reviews and meta-analyses.
