Background: The existing literature lacks conclusive evidence regarding the relationship between bronchopulmonary dysplasia (BPD) and cerebral palsy (CP). This large epidemiological study aimed to explore the co-occurrence of BPD and CP among children. Methods: This retrospective cohort analysis utilized the National Inpatient Sample (NIS) dataset from 2016 to 2019, investigating pediatric patients with BPD and CP diagnoses. Descriptive and inferential statistics, including univariate and multivariate regression analyses, were conducted to explore the association between BPD and CP. Results: Overall, 3,951,039 patients were analyzed. Among them, 28,880 patients had CP (n = 796 with BPD and n = 28,084 without BPD). The rates of intraventricular hemorrhage grade 3 and 4, central nervous system anomalies, chromosomal disorders, retinopathy of prematurity (≥grade 3), periventricular leukomalacia, prematurity, and low birth weight were significantly higher in the CP-with-BPD arm contrasted to the CP-without-BPD arm. Univariate regression demonstrated a significant BPD–CP association (odds ratio [OR] = 7.78, 95% confidence interval [CI]: 7.24–8.37, p < 0.0001). Multivariate analysis, adjusting for various confounders, reinforced this association (OR = 5.70, 95% CI: 5.17–6.28, p < 0.0001). We observed a significant association between increasing prematurity in neonates with BPD and an elevated risk of CP. Conclusions: This nationwide study identified a strong correlation between the co-occurrence of BPD and CP, though it does not establish causality. Rigorous adjustments revealed that patients with BPD appear to have a six-fold increased likelihood of being diagnosed with CP later on, compared to those without BPD. While aligned with the existing literature, this study represents the largest sample size with recommendations for targeted preventive strategies to mitigate the burden of CP.

Background and Objective: Cerebral palsy (CP) significantly impacts quality of life globally. Hip dysplasia (HD) is a common musculoskeletal issue in CP patients. This study investigates the prevalence, risk factors, and impact of HD on CP patients using a large national database. Materials and Methods: Data from the National Inpatient Sample (NIS) database (2016–2019) were used, identifying CP and HD diagnoses through ICD-10 codes. Baseline characteristics were tabulated. Univariate and multivariate logistic regression analyses examined predictors of HD development in CP patients, presenting data as odds ratios (ORs) with 95% confidence intervals (CIs). Results: Among 3,951,040 pediatric patients, 28,880 had CP (27,466 without HD, and 1414 with HD), and 3,922,160 did not have CP. CP significantly increased the likelihood of developing HD in univariate (OR = 35.03, 95% CI [33.01, 37.17], p < 0.0001) and multivariate (OR = 26.61, 95% CI [24.94, 28.40], p < 0.0001) analyses. Among patients with CP, race was significantly associated with HD, with ORs below 1 for all racial categories compared to Whites. Females had nearly twice the odds of HD compared to males (OR = 1.96, 95% CI [1.86, 2.05], p < 0.0001). Age was significantly associated with HD, with each additional year increasing the odds (OR = 1.03, 95% CI [1.026, 1.034], p < 0.0001). Individuals in the high 51st–75th income quartile had a 17% increase in the odds of HD (OR = 1.17, 95% CI [1.09, 1.25], p < 0.0001) compared to the low 1st–25th income quartile. Conclusions: This study reinforces the strong association between CP and HD, highlighting the need for further research and prospective studies to validate these findings.

Objectives: To investigate the incidence and risk factors for Acute kidney injury (AKI) following cardiac surgery in children with congenital heart diseases, and to identify modifiable factors that remain insufficiently studied. Acute kidney injury is common after cardiac surgery for children with congenital heart disease (CHD). Children with AKI are known to have complicated hospital courses, including their need for kidney replacement therapy, and have increased mortality. Methods: We conducted a retrospective analysis of children admitted to the pediatric cardiac intensive care unit (PCICU) at King Abdulaziz University Hospital over 7 years (2014–2021), using the Kidney Disease Improving Global Outcome (KDIGO) definitions and stages of AKI. Results: The cohort included a total of 628 children who had cardiac surgery for congenital heart disease, of whom 186 (29.6%) developed AKI. Children with AKI had significant difference than children without AKI in the following factors: (preoperative characteristics) age younger than one year, advanced score in risk adjustment for congenital heart surgery scores (RACHS-1 score), existing renal anomalies, hypoalbuminemia, and needed cardiac catheterization, (intraoperative factors) longer median cardiopulmonary bypass and aorta cross-clamping durations, had cardiac arrest and required ECMO and respiratory support. The most predictive variables for AKI development in these children were RACHS-1 score, cardiopulmonary bypass duration, cardiac catheter insertion, and presence of renal anomalies. Conclusions: This study provides valuable insights into the risk factors for AKI development in children with CHD following their cardiac surgery. These factors should be addressed in this patient population to reduce the risk of AKI and its following complications.
