Abstract Objective To analyze the factors associated with children's linear growth, according to the different subsystems of the 6Cs model and Bronfenbrenner's Bioecological Theory. Data sources Narrative review, carried out in the Scielo, Lilacs, Pubmed, and Science Direct databases, based on research using the terms Bioecological Theory, child growth, and risk factors, combined with the use of Boolean operators. Summary of findings According to the 6Cs model, proposed based on Bronfenbrenner's Bioecological Theory, the determining factors of children's linear growth are in six interrelated subsystems - cell, child, clan, community, country/state and culture. The empirical studies included in this review made it possible to analyze protection and risk factors within the subsystems. Among the protective factors: are adequate birth weight and satisfactory weight gain, breastfeeding for six months or more; proper hygienic habit of hand washing, proper elimination of feces, and access to clean water. As risk factors: low, birth weight and size, prematurity, multiple deliveries, short interval between deliveries, non-exclusive breastfeeding until the 3rd month, frequency and severity of infectious processes and anemia, little parental education, short maternal statur, inadequate maternal nutritional status, domestic violence, family poverty, food, and nutritional insecurity, living in rural areas or at high altitudes. Conclusion Children's linear growth is determined by interrelated factors that encompass aspects prior to the child's birth, as well as socioeconomic, political, family and community issues.

Abstract Objective The present study aimed to evaluate the effects of GH treatment on the body composition of children born with SGA. Methods This study is a systematic review of the literature. CINAHL, Embase; Medline/Pubmed, Scopus and Web of Science were searched from inception to March 2022. Results Four studies met the inclusion criteria, with an intervention time of 1 to 3 years, using doses from 0.03 to 0.07 mg/kg/day of GH. Bone densitometry by dual-energy X-ray absorptiometry (DXA) with whole-body scans was the most used method to assess body composition. Most studies (n= 3) had SGA children as a control group with the same characteristics as the case group; the mean age was similar between the groups (minimum of 5.1 ± 1.4 years and maximum of 6.7 ± 1 0.8 years) and all participants had an average height ≤ -3DP. The Lean Mass (LM) and Fat Mass (FM) outcomes of the studies were not presented in a standardized manner; thus, they cannot be compared. There was a significant increase in LM in the group treated with GH in relation to the pre-treatment period and in comparison, to the untreated control group. Three studies showed a significant decrease in FM at the end of the intervention period, and in two studies, this decrease occurred in the control group. Conclusions Despite the differences in the presentation of results and in the evaluation periods, the results of the studies showed that growth hormone favors the gain and maintenance of lean mass, and it also affects fat mass reduction and redistribution.

Abstract Objective Describe the epidemiological profile and social-economic burden that hydrocephalus patients represent to the national public health system, using data available at the online database of the Brazilian Health Ministry (DataSUS). Methods This is a populational study based on descriptive statistics of all clinical and surgical appointments included in the DataSUS database. Data included herein were collected between 2015 and 2021 and subdivided into three main groups, related to hydrocephalus incidence and mortality, hospitalizations, and financial costs. Results In the study period, 3993 new cases of congenital hydrocephalus were diagnosed, with 6051 deaths overall. The mortality rate in the country was 1.5/100000 live births and the prevalence was 0.374/100000 inhabitants. The number of hospitalizations resulting from treatment procedures and complications of hydrocephalus was 137,880 and there was a reduction of up to 27.2% during the SARS-CoV-2 pandemics concerning previous years. Total costs for hydrocephalus management in the country amounted to 140,610,585.51 dollars. Conclusions Hydrocephalus has a significant impact on public health budgets and pediatric mortality rates; however, it is probably underestimated, due to the paucity of demographic data and epidemiological studies in Latin America and, specifically, in Brazil. The dataSUS also has several limitations in accessing certain data related to hydrocephalus, making it difficult to have a more assertive understanding of the disease in Brazil. The results of this study provide important guidance for future research projects in clinical and experimental hydrocephalus and also the creation of public policies for better governance and care of hydrocephalus patients.

Abstract Objective Acute kidney injury (AKI) in the neonatal period is associated with worst outcomes as increased mortality and increased length of hospital stay. Very low birth weight (VLBW) newborns are at higher risk for developing several other conditions that are associated with worst outcomes. Understanding the risk factors for AKI may help to prevent this condition and improve neonatal care for this population. Methods This retrospective cohort study included 155 very low birth weight newborns admitted between 2015 and 2017. The authors compared the newborns who developed neonatal AKI with the non-AKI group and analyzed the main risk factors for developing AKI in the population. The authors also performed an analysis of the main outcomes defined as the duration of mechanical ventilation, length of stay, and death. Results From the cohort, a total of 61 (39.4%) patients had AKI. The main risk factors associated with Neonatal AKI were necrotizing enterocolitis (aOR 7.61 [1.69 - 34.37]; p = 0.008), neonatal sepsis (aOR 2.91 [1.17 - 7.24], p = 0.021), and hemodynamic instability (aOR 2.99 [1.35 - 6.64]; p = 0.007). Neonatal AKI was also associated with an increase in the duration of mechanical ventilation in 9.4 days (p = 0.026) and in an increase in mortality 4 times (p = 0.009), after adjusting for the other variables. Conclusion The present results highlight the importance of minimizing sepsis and necrotizing enterocolitis, as well as the importance of identifying hemodynamic instability, to prevent AKI and diminish the burden of morbimortality in VLBW newborns.

Abstract Objective The aim of this study was to analyze the effects of fluid overload related to mechanical ventilation, renal replacement therapy, and evolution to discharge or death in critically ill children. Methods A retrospective study in a Pediatric Intensive Care Unit for two years. Patients who required invasive ventilatory support and vasopressor and/or inotropic medications were considered critically ill. Results 70 patients were included. The mean age was 6.8 ± 6 years. There was a tolerable increase in fluid overload during hospitalization, with a median of 2.45% on the first day, 5.10% on the third day, and 8.39% on the tenth day. The median fluid overload on the third day among those patients in pressure support ventilation mode was 4.80% while the median of those who remained on controlled ventilation was 8.45% (p = 0.039). Statistical significance was observed in the correlations between fluid overload measurements on the first, third, and tenth days of hospitalization and the beginning of renal replacement therapy (p = 0.049) and between renal replacement therapy and death (p = 0.01). The median fluid overload was 7.50% in patients who died versus 4.90% in those who did not die on the third day of hospitalization (p = 0.064). There was no statistically significant association between death and the variables sex or age. Conclusions The fluid overload on the third day of hospitalization proved to be a determinant for the clinical outcomes of weaning from mechanical ventilation, initiation of renal replacement therapy, discharge from the intensive care unit, or death among these children.

Abstract Objective To evaluate the validity of the triage system CLARIPED in a pediatric population in the city of São Paulo, Brazil. Methods Prospective, observational study in a secondary-level pediatric emergency service from Sep-2018 to Ago-2019. A convenience sample of all patients aged 0-18 years triaged by the computerized CLARIPED system was selected. Associations between urgency levels and patient outcomes were analyzed to assess construct validity. Sensitivity, specificity, and positive and negative predictive values (PPV and NPV) to identify the most urgent patients were estimated, as well as under-triage and over-triage rates. Results The distribution of 24,338 visits was: RED 0.02%, ORANGE 0.9%, YELLOW 23.5%, GREEN 47.9%, and BLUE 27.7% (highest to the lowest level of urgency). The frequency of the following outcomes increased with increasing urgency: hospital admission (0.0%, 0.02%, 0.1%, 7.1% and 20%); stay in ED observation room (1.9%, 2,4%, 4.8%, 24.1%, 60%); use of ≥ 2 diagnostic/therapeutic resources (2.3%, 3.0%, 5.9%, 28.8%, 40%); ED length of stay (12, 12, 15, 99.5, 362 min). The most urgent patients (RED, ORANGE, and YELLOW) exhibited higher chances of using ≥ 2 resources (OR 2.55; 95%CI: 2.23-2.92) or of being hospitalized (OR 23.9; 95%CI: 7.17-79.62), compared to the least urgent (GREEN and BLUE). The sensitivity to identify urgency was 0.88 (95%CI: 0.70-0.98); specificity, 0.76 (95%CI: 0.75-0.76); NPV, 0.99 (95%CI: 0.99-1.00); overtriage rate, 23.0%, and undertriage, 11.5%. Conclusion This study corroborates the validity and safety of CLARIPED, demonstrating significant correlations with clinical outcomes, good sensitivity, and low undertriage rate in a secondary-level Brazilian pediatric emergency service.

Abstract Objective Advances in medicine have increased the life expectancy of pediatric patients with chronic illnesses, and challenges with the guided transition of adolescents and young adults from pediatric clinics to adult clinics have grown. The aim of this study was to better understand readiness and factors related to this transition process in Brazil. Method In this cross-sectional study of 308 patients aged from 16 to 21 years under follow-up in pediatric specialties, the degree of readiness for transition was assessed using the Transition Readiness Assessment Questionnaire (TRAQ) and its domains. Associations with demographic data, clinical data, socio-economic level, medication adherence, family functionality, and parental satisfaction with health care were evaluated. Results The median TRAQ score was 3.7 (3.2 - 4.2). Better readiness was associated with female patients, socio-economic class A-B, current active employment, higher level of education, not failing any school year, attending medical appointments alone, functional family, and a good knowledge of disease and medications. A low correlation was observed between TRAQ and age. TRAQ presented good internal consistency (alpha-Cronbach 0.86). In the multiple linear regression, TRAQ score showed a significant association with female gender, advanced age, socio-economic class A-B, better knowledge of disease and medications, and independence to attend appointments alone. Conclusion TRAQ instrument can guide healthcare professionals to identify specific areas of approach, in order to support adolescents with chronic disease to set goals for their own personal development and improve their readiness to enter into the adult healthcare system. In this study, some factors were related to better TRAQ scores.

Abstract Objectives To evaluate the therapeutic effect of Saccharomyces boulardii supplementation on jaundice in premature infants undergoing phototherapy. Methods In this article, the authors reviewed 100 hospitalized jaundiced premature infants under 35 weeks of gestational age. All infants were assigned to a control group (n= 45) and a treatment group (n= 55) randomly. The infants in the treatment group received S. boulardii supplementation by undergoing phototherapy and the infants in the control group were only treated by phototherapy. The total serum bilirubin levels were detected before and at the end of phototherapy, and transcutaneous bilirubin levels were measured on the 1st, 4th, 8th and 15th day of treatment. The duration of jaundice resolution and phototherapy, stool frequency, and characteristics were compared after phototherapy. Results The duration of jaundice resolution and phototherapy were shortened. Total serum bilirubin level was lower than the control group at the end of phototherapy (p < 0.05). Transcutaneous bilirubin levels decreased more significantly on the 8th and 15th day of treatment (p < 0.05), while there were no significant differences on the post-treatment 1st and 4th day (p > 0.05). In addition, bowel movements including stool frequency and Bristol Stool Form Scale ratings of stools also improved after treatment. Conclusions S. boulardii in combination with phototherapy is effective and safe in reducing bilirubin levels and duration of phototherapy, accelerating jaundice resolution in premature infants with jaundice. The procedure also provided an ideal therapeutic effect of diarrhea induced by phototherapy to promote compliance and maternal-infant bonding.

Abstract Objective To assess the prevalence of GERD exclusively by means of multichannel intraluminal impedanciometry associated with pH monitoring (MIIpH) and compare it with respiratory symptoms in children with CF. To compare MIIpH with pHmetry alone to perform GERD diagnosis. Methods An analytical cross-sectional study was conducted with children diagnosed with CF who underwent MIIpH. Clinical and laboratory markers, including respiratory and digestive symptoms, were used for comparative analyses. High-resolution chest computed tomography was performed on patients with symptoms of chronic lung disease. Severity was classified according to the Bhalla score. Results A total of 29 children < 10 yo (18 girls) were evaluated; 19 of whom with physiological GER and 10 with GERD. Of the children with GERD, seven had predominantly acid GER, two acid+non-acid GER, and one non-acid GER. Three patients had GERD diagnosed only by MIIpH. Bhalla scores ranged from seven to 17.75 with no significant relationship with GERD. The number of pulmonary exacerbations was associated with a decrease in esophageal clearance regardless of the position in pHmetry and MIIpH. Conclusions The prevalence of GERD was 34% in children with CF. There was no association between respiratory disease severity and GER types. MIIpH detected 30% more patients with GERD than pHmetry.

Abstract Objective To investigate the relationship between lactate acid level and hospitalization mortality in neonatal necrotizing enterocolitis (NEC). Method Paediatric-specific critical care database collected clinical data from the intensive care unit of Children's Hospital Affiliated to Zhejiang University Medical College from 2010 to 2018. Clinical and laboratory examination information of NEC patients was collected and divided into the death group and discharge group to find out the risk factors affecting the prognosis through univariate and multivariate analysis. Results Among 104 NEC neonates, the admission age was 7.5 days and the weight was 2.03 kg. Comparing the death group with the discharge group, there were significant differences in therapeutic regimen, pH, serum albumin, total protein, creatinine and lactate acid. Multivariate and threshold effect analysis showed that lactate acid had a linear correlation with hospital mortality, and newborns who died in the hospital had much higher lactate levels than those who were discharged. The mortality of NEC newborns increased by 40-45% for every 1 mmol/L increase in lactate acid level. Conclusions There was a correlation between lactate acid level and hospital mortality in newborns with NEC, and lactate acid level was an important index to evaluate the prognosis of NEC.

Abstract Objective To investigate associations of maternal and cord blood cytokine patterns with newborn size and body composition. Methods This cross-sectional study involved 70 pregnant women and their healthy newborns selected from the “Araraquara Cohort Study”. Newborn anthropometric measurements were recorded at birth. Body composition was evaluated by air displacement plethysmography. Maternal blood samples were collected from pregnant women between 30 and 36 weeks of gestation, and umbilical cord blood samples were collected immediately after placenta discharge. The concentrations of the cytokines were determined in plasma by ELISA. Multiple linear regression models were used to assess associations between maternal and cord blood cytokine concentrations and newborn anthropometry and body composition measurements. Results Maternal plasma TGF-β1 concentration was inversely associated with newborn weight (β= -43.0; p= 0.012), length (β= -0.16, p= 0.028), head circumference (β= -0.13, p= 0.004), ponderal index (β= -0.32, p= 0.011) and fat-free mass (β= -0.05, p= 0.005). However, the association persisted just for head circumference (β= -0.26; p= 0.030) and ponderal index (β= - 0.28; p= 0.028), after adjusting for pre-gestational BMI, gestational weight gain, gestational age, hours after delivery, newborn sex, smoking and alcohol consumption. Conclusions Maternal plasma TGF-β1 concentration may be involved in the regulation of newborn size, mainly head circumference and ponderal index. Further cohort studies are necessary to investigate the role of TGF-β1 in different trimesters of pregnancy and its effect during the early stages of fetal development.

Abstract Objectives Adherence problems have a great impact on auto-immune Rheumatic Diseases (AIRD). The COVID-19 pandemic may have worsened treatment adherence. The aims of this study were to measure treatment adherence to identify an earlier risk of poor adherence and measure families’ satisfaction with the health service during the pandemic. Methods Prospective observational study with 50 parents/children and adolescents with recent AIRD diagnosis. Initially, they answered questions (demographic data, disease) and completed the Pediatric Rheumatology Adherence Questionnaire (PRAQ), after 6 months they completed the Morisky-Green Test (MGT), Brief Medication Questionnaire (BMQ), Compliance Questionnaire for Rheumatology (CQR-19) and Pediatric Quality of Life Inventory Questionnaire 3.0 (PedsQlTM-SSS). The patient's medical records from the previous 12 weeks were reviewed for global and medication adherence data. Results The mean global adherence score was 94.3 ± 10.0, for medication adherence 97.3 ± 9.3, and for PRAQ questionnaire 5.2 ± 1.5. The authors observed agreement between MGT, BMQ, CQR-19, PedsQLTM-SSS scores and medication adherence rate, but not with global adherence rate. There were no associations between demographic characteristics, disease diagnosis, and adherence. No associations between PRAQ scores and values and global/medication adherence rates were observed. No variables were shown to be predictors of good adherence. The mean PedsQLTM-SSS rate was 92.1 ± 6.8. Conclusion The high values of MGT, BMQ, CQR-19 questionnaire scores were in agreement with the medication adherence rate. Despite the pandemic, the global and medication adherence rates were good. It was not possible to demonstrate the PRAQ's predictive power. The authors weren't able to establish an association between families’ satisfaction and treatment adherence rates.

Abstract Objective To verify the performance of the Net Promoter Score (NPS) as a tool to assess parental satisfaction in pediatric intensive care units (PICUs). Methods The authors conducted an observational cross-sectional multicenter study in the PICUs of 5 hospitals in Brazil. Eligible participants were all parents or legal guardians of PICU-admitted children, aged 18 years or over. The NPS was administered together with the EMpowerment of PArents in THe Intensive Care (EMPATHIC-30), used as the gold standard, and a sociodemographic questionnaire. For analysis, the results were dichotomized into values greater than or equal to the median of the tests. The associations between the 2 tools were evaluated and the distribution of their results was compared. Results The parents or legal guardians of 78 PICU-admitted children were interviewed. Of the respondents, 85% were women and 62% were in a private hospital. The median NPS was 10 (IQR, 10-10), and the median EMPATHIC-30 score was 5.7 (IQR, 5.4-5.9). Compared with the gold standard, the NPS had a sensitivity of 100% at all cutoff points, except at cutoff 10, where the sensitivity was slightly lower (97.5%). As for specificity, NPS performance was poorer, with values ranging from 0% (NPS ≥ 5) to 47.4% (NPS = 10). Conclusions NPS proved to be a sensitive tool to assess parental satisfaction, but with poor ability to identify dissatisfied users in the sample.

Abstract Objective To analyze the follow-up, in specialized outpatient clinics, of infants reported with congenital syphilis during the penicillin shortage. Method A cross-sectional study was carried out in ten public maternity hospitals affiliated with the Brazilian Unified Health System in the city of Fortaleza, state of Ceará. Clinical records of infants reported with congenital syphilis who were born alive in 2015 were used to describe correlates of attendance at recommended clinical follow-up appointments. Results A total of 469 infants reported with CS from January 1/2015 to December 31/2015 were included in the analysis. The results show that most infants did not attend the follow-up visits (368/469, 78.5%) and the main associated factors are that the follow-up clinic is located in a different hospital from that where the infant was born (OR: 3.7; CI: 2.20-6.22; p< 0.001) and the use of illicit drugs by the mother (OR: 3.2; CI: 1.57-6.87; p= 0.002). Only 33.7% (34/101) were followed until discharge. Conclusion The majority of infants with reported congenital syphilis during this period did not attend the follow-up visits. Public health efforts aimed at reaching the parents of infants with CS should be a priority to ensure appropriate clinical identification and management of the associated outcomes of this vertically transmitted infection.
