METHOD A systematic review of randomized clinical trials of Ex- or En-DCR with and without the use of MMC to treat primary acquired nasolacrimal duct obstruction (NLDO) was done. Two authors independently searched six databases from 1990 to 2019, using the terms "dacryocystorhinostomy" and "mitomycin-C." Statistical and meta-analyses were performed using RevMan 5.3 software. RESULTS Twenty-seven studies involving 2158 surgeries were included in this systematic review. The Ex-DCR group comprised 14 studies [odds ratio (OR) 2.74; 95% confidence intervals (CI) 1.54-4.87; I2 = 30%], while the En-DCR group 13 studies (OR 1.69; 95% CI 1.21-2.37; I2 = 0%). The use of MMC slightly increased the success rate of Ex- or En-DCR (OR 2.1; 95% CI 1.52-2.9; I2 = 14%). CONCLUSION The intraoperative use of MMC is safe and slightly improves the success rate of Ex- or En-DCR. However, the evidence was very weak.PURPOSE The purpose of this study was to examine the longitudinal developmental patterns of mental health (i.e., physical, psychosocial, and executive functioning) and movement behaviors (i.e., sedentary behavior and moderate-to-vigorous physical activity [MVPA]) between Hispanic and non-Hispanic children. METHOD We tracked 153 children for 3 years from kindergarten (time 1) to third grade (time 2; 91 Hispanic; mean age = 5.36, SD = .48). Physical, psychosocial, and executive functioning was assessed using validated surveys, while school-based sedentary behavior and MVPA were assessed by accelerometers. RESULT A 2 × 2 (time × ethnicity) factorial repeated measures MANCOVA (gender and SES as covariates) revealed significant ethnicity effect (p = .05) and time by ethnicity interaction effect (p  .05) over time. CONCLUSION Ethnic disparities in mental health between Hispanic and non-Hispanic child
