Purpose: To compare clinical outcomes associated with pediatric oropharyngeal dysphagia, before and after videofluoroscopic swallow study (VFSS) and feeding strategies recommendations. Methods: A longitudinal, analytical uncontrolled study with evaluation before and after VFSS was performed. Children between 0 and 24 months were included in the study. Each participant received recommendations for the therapeutic management of oropharyngeal dysphagia after the VFSS, as well as follow-up care at a hospital Outpatient Clinic for Pediatric Dysphagia in order to monitor feeding and swallowing complaints. The respiratory and feeding outcomes were compared. Results: A penetration/aspiration event was observed in 61% of the videfluoroscopic exams (n=72). Feeding strategies to improve biomechanical coordination and swallowing safety were required for 97% of the examined children. After the exam, there was a reduction in the use and length of antibiotic therapy (p=0.036), in the number of children who had been admitted to hospital (p<0.001), in the frequency (p=0.037), and in the length of hospitalization (p=0.025). There was an increase in combined oral and enteral feeding in relation to isolated feeding routes (p=0.002). Conclusions: This study data shows a high prevalence of penetration / aspiration in VFSS in this population. The therapeutic management of oropharyngeal dysphagia, guided by objective examinations, was associated with a decrease in respiratory morbidity in children included.

Objective: To evaluate the oxygen uptake at peak exercise (VO2 peak) and to correlate with lung volume and capacity and body composition of children and adolescents with cystic fibrosis (CF). Methodology: Cross-sectional study with CF patients treated at the pediatric pulmonology outpatient clinic of a public hospital in Porto Alegre, aged ≥ 7 years up to 18 years. Study assessments included: cardiopulmonary stress testing, plethysmography, and body composition assessment using body bioimpedance. Results: Thirty patients were studied, with a mean peak VO2 of 1.511 ± 0.539 liters in the population studied. Correlation analysis showed a strong correlation between peak VO2 in liters and lean mass (r = 0.77 and p <0.001), and strong and inverse correlation with fat percentage (r = - 0.77 and p <0.001). ), a strong correlation with forced vital capacity (FVC) in liters (r = 0.72 and p <0.001) and forced expiratory volume in the first second (FEV1) also in liters (r = 0.69 and p <0.001). We observed a strong correlation between load (W) and lean mass and during CPET (r = 0.64 and p <0.001), and inversely with fat percentage (r = -0.64 and p <0.001). This study showed that patients with higher lean body composition have a better performance on cardiopulmonary testing, contributing to greater exercise tolerance.
