  This study examined the role of parenting practices on preschoolers’ secure exploratory behaviors; specifically, the extent to which parenting practices mediate the relationship between socio-economic status, perceived neighborhood support, parental depression and children’s exploratory behaviors. The participants (n = 3268) were parents of young children (Mage = 50.82 months; 50% identified as Latinx). Structural equation models revealed that parenting practices had a positive direct association with preschoolers’ secure exploration. Parental depression had a negative association with preschoolers’ secure exploration, whereas perceived neighborhood support and socio-economic status had positive associations with secure exploration. These associations were significantly mediated through parenting practices. The results demonstrate the crucial role parents play in fostering their child’s secure exploration by providing a secure base and exploratory experiences, and can inform policy and family education programs.

  There are no established guidelines regarding management of antibiotics for patients specifically undergoing urethral reconstruction. Our aim was to minimize antibiotic use by following a standardized protocol in the pre-, peri- and postoperative setting, and adhere to American Urological Association antibiotic guidelines. We hypothesized that prolonged suppressive antibiotics post-urethroplasty does not prevent urinary tract infection and/or wound infection rates..We prospectively treated 900 patients undergoing urethroplasty or perineal urethrostomy at 11 centers over 2 years. The first-year cohort A received prolonged postoperative antibiotics. Year 2, cohort B, did not receive prolonged antibiotics. A standardized protocol following the American Urological Association guidelines for perioperative antibiotics was used. The 30-day postoperative infectious complications were determined. We used chi-square analysis to compare the cohorts, and multivariate logistic regression to identify risk factors..The mean age of participants in both cohorts was 49.7 years old and the average stricture length was 4.09 cm. Overall, the rate of postoperative urinary tract infection and wound infection within 30 days was 5.1% (6.7% in phase 1 vs 3.9% in phase 2, p=0.064) and 3.9% (4.1% in phase 1 vs 3.7% in phase 2, p=0.772), respectively. Multivariate logistic regression analysis of patient characteristics and operative factors did not reveal any factors predictive of postoperative infections..The use of a standardized protocol minimized antibiotic use and demonstrated no benefit to prolonged antibiotic use. There were no identifiable risk factors when considering surgical characteristics. Given the concern of antibiotic over-prescription, we do not recommend prolonged antibiotic use after urethral reconstruction.
