Objective: To assess the effect of Passy-Muir® Valve (PMV) tolerance on respiratory illness and respiratory related hospital admissions in tracheostomy-dependent children. Methods: Retrospective cohort study of 262 patients who underwent tracheostomy placement between 2012 and 2018 at a tertiary free-standing children’s hospital. Outcome measures studied were number of reported upper respiratory infections and respiratory related hospitalizations per year (RRH/year). Results: About 135 (51.5%) tracheostomy-dependent children underwent PMV trials, and 106 (78.5%) of these children were able to tolerate PMV for at least 1 hour daily. When comparing children who tolerated PMV versus those who did not, the latter group had significantly higher rates of subglottic stenosis but no significant differences in RRH/year or average age. In those children who tolerated PMV and achieved routine use of PMV > 1 hour/day, an average of 1.14 RRH/year occurred prior to PMV tolerance, as compared with 0.57 RRH/year after PMV tolerance ( P = .003). Multivariate analysis shows that in patients <2 years, there is a significant decrease in RRH/year after PMV tolerance is attained (1.53 vs 0.76, P = .001), independent of indication for tracheostomy. Conclusion: In tracheostomy-dependent children who tolerate PMV use routinely >1 hour/day there are decreased rates of respiratory related hospitalizations (RRH). Children <2 years of age have the most impact of RRH, with rates that are significantly lower with routine use of the PMV.
Background. Despite evidence that social network members influence the eating behaviors of adults, no study to date has had the primary aim of examining children as support partners for parents in a weight loss intervention. Aim. To evaluate parent adherence with eating/exercise goals and weight loss in a 6-month study engaging children as support partners. Method. Adults with obesity (body mass index ≥ 30 kg/m2, n = 102) and at least one child ≥12 years were randomized to a child support or control group. In the child support group, children enrolled with their parent and engaged in a supportive behavior 2 days/week. In the control group, there was no enrolled child support. Parents in both groups selected a healthy eating strategy and daily step goal. Results. There was no difference in weight loss between the child support and control groups (−5.97 vs. −5.42 lbs, p = .81). In the child support group, 30% of children did not engage in the study. The majority of parents whose children did not engage withdrew from the study. In secondary analyses, parent adherence with eating/exercise goals increased with the days of child support ( p < .001). For all participants, low chaos in the home environment ( p < .04) and increased parent adherence with follow-ups ( p < .008) predicted weight loss. Conclusions. We found no treatment effect of child support on weight loss. Active child support of eating/exercise goals appeared to facilitate goal adherence, while anticipated but unrealized child support may have had iatrogenic consequences. Further investigation of family-focused weight loss interventions is warranted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
