Objective: To assess a comparative analysis of the ROX index, Wood-Downes-Ferrés score (WDF), p-ROXI, and the SpO2/FiO2 ratio as predictors of high-flow nasal cannula (HFNC) failure in children hospitalized for bronchiolitis.

Methods: Data were extracted from the clinical trial "Comparison between HFNC and NIV in children with acute respiratory failure caused by bronchiolitis" conducted at a tertiary Brazilian hospital (Emergency Department and PICU). The inclusion criteria were children under 2 years of age admitted for bronchiolitis who developed mild to moderate respiratory distress and were eligible for HFNC therapy.

Children are at higher risk of atelectasis due to their anatomical and physiological particularities. Several physiotherapy techniques are used to treat atelectasis, but only four studies cite methods in pediatric patients undergoing Invasive Mechanical Ventilation (IMV). The objective of this study was to evaluate the Structured Respiratory Physiotherapy Protocol (SRPP) for airway clearance and lung reexpansion for infants on IMV with atelectasis.

Article Synopsis
  • - The study aimed to determine if high-flow nasal cannula (HFNC) therapy is at least as effective as noninvasive ventilation (NIV/BiPAP) for treating bronchiolitis-related respiratory failure in children under 2 years old.
  • - Conducted in a Brazilian hospital, the trial involved 126 children in each treatment group, with assessments of their health and treatment outcomes, including the need for intubation and length of hospital stay.
  • - Results showed a lower intubation rate in the HFNC group (23%) compared to the NIV group (29%), and while the difference was not statistically significant, HFNC therapy resulted in lower sedation needs and hospital stays, indicating it could be a

Objective: This study aimed to evaluate the Neuropsychomotor Development (NPMD) of newborns exposed to SARS-CoV-2 in the perinatal period using the Bayley III scale at 6 months of age.

Methods: Childcare appointments were scheduled for the included newborns in the study. During the 6-month consultation, the Screening Test for Bayley III Scale and, based on it, children were classified as "low risk", "moderate risk" or "high risk" in the domains: of cognitive, receptive language, expressive language, fine motor, and gross motor.

COVID-19's severity has been associated with a possible imbalance in the cross-regulation of cytokines and vascular mediators. Since the beginning of the pandemic, kidney transplant recipients (KTRs) have been identified as patients of high vulnerability to more severe diseases. Thus, aiming to describe the patterns of cytokines and vascular mediators and to trace patients' differences according to their KTR status, this prospective study enrolled 67 COVID-19 patients (20 KTRs) and 29 non-COVID-19 controls before vaccination.

Objective: To describe current clinical practices related to the use of high-flow nasal cannula therapy by Brazilian pediatric intensivists and compare them with those in other countries.

Methods: A questionnaire was administered to pediatric intensivists in North and South America, Asia, Europe, and Australia/New Zealand for the main study. We compared the Brazilian cohort with cohorts in the United States of America, Canada, the United Kingdom, and India.

Objective: To evaluate whether there was any impact on the number of pediatric extracorporeal membrane oxygenation runs and survival rates in the years subsequent to the 2009 pandemic.

Methods: We studied two different periods of extracorporeal membrane oxygenation support for respiratory failure in children by analyzing datasets from the Extracorporeal Life Support Organization. Autoregressive integrated moving average models were constructed to estimate the effect of the pandemic.

Objective: Acute respiratory distress syndrome (ARDS) can be a devastating condition in children with cancer and alveolar recruitment maneuvers (ARMs) can theoretically improve oxygenation and survival. The study aimed to assess the feasibility of ARMs in critically ill children with cancer and ARDS.

Methods: We retrospectively analyzed 31 maneuvers in a series of 12 patients (median age of 8.

We evaluated the performance of PRISM IV for pediatric cancer patients, and adapted and calibrated the algorithm to calculate mortality probabilities for these patients. An ambidirectional cohort was used, and data were collected from March 2017 prospectively to April 2019, and retrospectively to November 2014. The derivation set for model building contained 500 patients, and a validation set of 503 patients.
