Height, weight, and cardiorespiratory fitness (CRF) (i.e., Fitnessgram Progressive Aerobic Cardiovascular Endurance Run) were measured inchildren (5—12 years old) in 3 schools (2 traditional, 1 year-round, n = 990 students, age = 8.6 土 2.4 years, 53.1% male, 68.9% African American) from1 school district. Structure (represented by the presence of a school day) was the independent variable. Changes in body mass index (BMI), age- andsex-specific BMI z-scores (zBMI), BMI percentile, percent of overweight or obese children, and CRF (Progressive Aerobic Cardiovascular EnduranceRun laps completed) were assessed for summer 2017 (May—August 2017), school year 2017/2018 (August 2017—May 2018), and summer 2018(May—August 2018). Primary analyses examined the overall change in weight and CRF from summer 2017 until summer 2018 via multilevel mixedeffects regression, with group (traditional vs. year-round calendar), time, and a group-by-time interaction as the independent variables. Secondaryregression analyses estimated differences in change within and between groups during each time period, separately.Results. Year-round students gained less BMI (difference in A = —0.44, 95% confidence interval (CI): —0.67 to —0.03) and less CRF (differencein △ = — 1.92, 95%CI: —3.56 to —0.28) than students attending a traditional school overall. Compared with traditional students, during both sum・mers, year-round students gained less BMI (summer 2017 difference in A = —0.15, 95%CI: —0.21 to —0.08;summer 2018 difference in△ = —0.16, 95%CI: —0.24 to —0.07) and zBMI (summer 2017 difference in A = —0.032, 95%CI: —0.050 to —0.010;summer 2018 difference in△ = —0.033, 95%CI: —0.056 to —0.009), and increased CRF (summer 2017 difference in A = 0.40, 95%CI: 0.02—0.85;summer 2018 differencein A = 0.23, 95%CI: —0.25 to 0.74). However, the opposite was observed for the school year, with traditional students gaining less BMI andzBMI and increasing CRF compared with year-round students (difference in BMI A = 0.05, 95%CI: 0.03—0.07;difference in zBMI A = 0.012,95%CI: 0.005—0.019;difference in Progressive Aerobic Cardiovascular Endurance Run laps A = —0.43, 95%CI: —0.58 to —0.28).Conclusion'. The year-round school calendar had a small beneficial impact on children's weight status but not CRF. It is unclear if this benefit tochildren's weight would be maintained because gains made in the summer were largely erased during the school year. Trajectories of weight andCRF gain/loss were consistent with the structured days hypothesis.展开更多

Methods We identified patients undergoing percutaneous closure of ASD with device using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) procedure code 35.52 from the National Inpatient Sample, years 2002–2011. Patients with age ≤ 18 years and primary diagnosis code 745.5 for ASD were included. Hospital volume was calculated using unique identification numbers and divided into tertiles for analysis. Multivariate regression analysis was performed to determine independent predictors of procedure-related complications which were coded using specific codes released by Healthcare Cost and Utilization Project. Results 6162 percutaneous ASD closure procedures were analyzed. There was no mortality associated with percutaneous ASD closure. Cardiac complications (9.5%) were most common. On multivariate analysis, age increment of 3 years decreased the odds of developing complications (OR 0.83, 95% CI 0.79–0.87,P < 0.001). Odds of developing complications in the 2nd (OR 0.74, 95% CI 0.62–0.89,P = 0.007) and 3rd tertiles (OR 0.34, 95% CI 0.27–0.42,P < 0.001) were lower as compared to the 1st tertile of hospital volume. Conclusion Increasing annual hospital volume is an independent predictor of lower complication rates in percutaneous ASD closure cases with no associated mortality in pediatric patients.展开更多
