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.

Objectives: A recent European randomized trial - Tracheal Occlusion To Accelerate Lung Growth - demonstrated that fetoscopic endoluminal tracheal occlusion (FETO) is associated with increased postnatal survival among infants with severe congenital diaphragmatic hernia (CDH). However, this differs in middle-income countries such as Brazil, where abortion is illegal and neonatal intensive care is inadequate. This study evaluated the effects of FETO on improving the survival of infants with moderate-to-severe CDH in isolated and non-isolated cases.

This study aims to analyze the main risk factors for acute kidney injury in the subgroup of very-low birth weight newborns, using the diagnosing criteria of the Kidney Disease Improving Global Outcomes (KDIGO) or the Acute Kidney Injury Network (AKIN). A systematic review of the literature was performed on the EMBASE and PubMed platforms. Studies that evaluated the risk factors for developing AKI in VLBW newborns were included.

Article Synopsis
  • - The study evaluated the use of whole genome sequencing (WGS) as a first-step diagnostic tool for critically ill infants in Brazilian neonatal intensive care units, with collaboration between private and public hospitals.
  • - In a cohort of 21 infants suspected of genetic diseases, WGS provided a diagnostic yield of 57%, identifying various genetic variants, including 10 novel ones not found in existing databases.
  • - The research highlighted the advantages of WGS over traditional genetic tests in diagnosing conditions like dysmorphic syndromes while also discussing the challenges and potential implications of integrating WGS into Brazil's healthcare system.

Objective: Lactate is a marker of hypoperfusion in critically ill patients. Whether lactate is useful for identifying and stratifying neonates with a higher risk of adverse outcomes remains unknown. This study aimed to investigate the association between lactate and morbidity and mortality in neonates.

A new outbreak of hepatitis of unknown origin raised awareness in the international community. A few reports have attempted to associate new cases with adenovirus infection and the immunologic effects of previous SARS-CoV-2 infections through a superantigen mechanism. Moreover, according to a case series, viral isolates were identified in 7 of 10 cases of pediatric patients with hepatitis of unknown origin and acute liver failure.

Objective: To describe the incidence and to analyze risk factors associated with cholestasis in neonates with gastroschisis.

Methods: This is a retrospective cohort study in a tertiary single center analyzing 181 newborns with gastroschisis between 2009 and 2020. The following risk factors associated with cholestasis were analyzed: gestational age, birth weight, type of gastroschisis, silo closure or immediate closure, days of parenteral nutrition, type of lipid emulsion, days of fasting, days to reach a full diet, days with central venous catheter, presence of infections, and outcomes.

Delirium is a common disorder in intensive care units, being associated with greater morbidity and mortality. However, in neonatal intensive care units, delirium is rarely diagnosed, due to the low familiarity of the neonatologist with the subject and the difficulties in the applicability of diagnostic questionnaires. This case report aimed to assess the presence of this disorder in this group of patients and identify the difficulties encountered in the diagnosis and treatment.

Background: Sodium and chloride disturbances have attracted increasing attention in recent years. Many pathophysiological effects are associated with hyperchloremia, including reduction in mean arterial pressure and acute renal disease. Pediatric patients undergoing liver transplantation are at risk of developing various electrolyte and biochemical abnormalities, with an impact on their postoperative outcomes.

Article Synopsis
  • Acute kidney injury (AKI) in very low birth weight (VLBW) newborns can lead to increased mortality and longer hospital stays, making it crucial to understand its risk factors.
  • A study involving 155 VLBW newborns found that 39.4% developed AKI, with significant risk factors including necrotizing enterocolitis, neonatal sepsis, and hemodynamic instability.
  • The presence of AKI was linked to a longer duration of mechanical ventilation and a fourfold increase in mortality, emphasizing the need for targeted prevention strategies in vulnerable newborns.

Objective: Among the mechanisms proposed for the development of bronchopulmonary dysplasia is the increase in the pulmonary inflammatory process and oxidative stress. Thus, the control of this process may result in improvements in bronchopulmonary dysplasia-related outcomes. This study aims to analyze the current scientific evidence regarding the use of budesonide, a potent anti-inflammatory drug, associated with a pulmonary surfactant to prevent bronchopulmonary dysplasia.

Objective: Pediatric acute liver failure (PALF) is a heterogeneous, rare, and severe condition, which outcome is survival due to liver spontaneous recovery or death. The patients who do not recover may be allocated to liver transplantation, which is the standard treatment. This study aimed to build a prognostic model to support the clinical decision to indicate liver transplantation for patients with PALF in a Brazilian center.

Article Synopsis
  • A study was conducted in two pediatric hospitals to analyze how nutritional risk and inflammatory markers affect the length of stay (LOS) for children and adolescents hospitalized with COVID-19 between March and December 2020.
  • The study included 73 patients, with 27.4% showing high nutritional risk (STRONGkids score ≥4), which correlated with a longer LOS, even after adjusting for various factors.
  • Findings revealed that high nutritional risk and certain inflammatory markers (like low albumin and lymphocytes, high CRP) were linked to extended hospital stays for COVID-19 patients.
