Overall and Sex-Specific Associations Between Fetal Adversity and Child Development at Age 1 Year: Evidence From Brazil.

A growing body of epigenetic research suggests that in-utero adaptations to environmental changes display important sex-specific variation. We tested this heterogeneous adaptation hypothesis using data from 900 children born at the University Hospital in São Paulo, Brazil, between October 2013 and April 2014. Crude and adjusting linear models were used to quantify the associations between prematurity, being small for gestational age, and children's physical and mental development at 12 months of age. Prematurity was negatively associated with neuropsychological development in final models (z score difference, -0.42, 95% confidence intervals: -0.71, -0.14), but associations did not vary significantly by sex. For being small for gestational age, associations with height-for-age, weight-for-age, and neuropsychological development were also negative, but they were systematically larger for male than for female infants (P < 0.05 for all). These results suggest that male fetuses may be more vulnerable to intrauterine adversity than female fetuses. Further research will be needed to better understand the mechanisms underlying these sex-specific associations.

The specific and combined role of domestic violence and mental health disorders during pregnancy on new-born health.

BACKGROUND: Addressing impaired foetal growth is recognized as a public health priority. Certain risk factors for this condition, such as poor nutritional status at birth, have been found to be highly correlated with poverty. However, the role of psychosocial factors, specifically the mother's mental health and exposure to violence during pregnancy, have yet to be further explored. Our objective was to determine if there is a measurable association between combined psychosocial factors, specifically domestic violence and mental disorders, and birth outcomes, specifically birth nutritional status and preterm delivery. METHODS: We followed 775 women from an underserved, urban area, beginning their 28th week of gestation. Diagnostic interviews were performed to determine if any of the mothers had any of the following disorders: mood disorder, anxiety, obsessive-compulsive disorder (OCD), substance dependence, psychotic disorder, or anti-social personality disorder. Physical, psychological, and sexual domestic violence were also assessed. RESULTS: Domestic violence and mental disorders were highly correlated in our sample. About 27.15% of the women in our study experienced domestic violence, and about 38.24% of them were diagnosed with mental disorders. The main association we found between combined psychosocial factors and neonate outcomes was between anxiety (IRR = 1.83; 95%CI = 1.06-3.17)/physical violence (IRR = 1.95; 95%CI = 1.11-3.42) and the rate of small-for-gestational age (SGA) in new-borns. More specifically, the combination of anxiety (beta = -0.48; 95%CI = -0.85/-0.10) and sexual violence (beta = -1.58; 95%CI = -2.61/-0.54) was also associated with birth length. Maternal risk behaviours such as smoking, drinking, inadequate prenatal care, and inadequate weight gain could not sufficiently explain these associations, suggesting that these psychosocial factors may be influencing underlying biological mechanisms. CONCLUSION: Domestic violence against women and mental disorders amongst pregnant women are extremely prevalent in under-resourced, urban areas and ultimately, have detrimental effects on birth outcomes. It is imperative that actions be taken to prevent violence and improve mental health during pregnancy.

Causal Pathways Between the Acute Experience of Violence During Pregnancy and Fetal Intrauterine Growth Restriction: A Cohort Study.

Introduction: Violence during pregnancy (VDP) is a prevalent global issue with dire consequences for the mother and the developing fetus. These consequences include prematurity, low birthweight, and intrauterine growth restriction (IUGR), but its pathways remain elusive. This study investigated the causal pathways between VDP and IUGR using mediation analysis. Methods: A prospective population-based birth cohort was followed from the beginning of the third gestational trimester to the second year of life. IUGR was defined by the Kramer index, and information on VDP was collected using the WHO-Violence Against Women (WHO VAW) questionnaire. Cases were considered positive only when no other life episodes were reported. Ten different mediators were analyzed as possible pathways based on previous research. Path analysis was conducted to evaluate these relationships. Results: The path analysis model included 755 dyads and presented an adequate fit. Violence during pregnancy showed a direct effect (ß = -0.195, p = 0.041) and a total effect (ß = -0.276, p = 0.003) on IUGR. Violence was associated with gestational depression or anxiety, tobacco and alcohol consumption, changes in blood pressure, and the need for emergency care, but these did not constitute mediators of its effect on IUGR. The sum of the indirect effects, however, showed a significant association with IUGR (ß = -0.081, p = 0.011). Conclusion: The acute experience of violence during pregnancy was associated with IUGR, primarily via a direct pathway. An indirect effect was also present but not mediated through the variables analyzed in this study. The robust strength of these associations underscores the negative health consequences of violence against women for the succeeding generation.

Mother-infant bonding and postpartum depression during the COVID-19 pandemic - a risk for nurturing care and child development.

OBJECTIVE: The COVID-19 pandemic Increased the risk of impairing the mother-infant bonding. The objectives of this study were to evaluate the early bond established between mother and infant and postpartum depression (PPD) in pregnancies that occurred during the pandemic period, to identify the factors that may have influenced these outcomes and to verify if there was an association between bonding and probable PPD. METHODS: This is a cross-sectional study of postpartum women from a public maternity hospital in the city of São Paulo conducted from February to June 2021, involving 127 mother-baby dyads. The initial data were collected in the immediate postpartum period and between 21-45 days after birth, using a semi-structured questionnaire on sociodemographic characteristics, gestational and birth conditions, and baby characteristics; the Edinburgh Postnatal Depression Scale (EPDS) and Postpartum Bonding Questionnaire (PBQ) were used to evaluate PPD and bonding, respectively. RESULTS: The presence of probable PPD and unplanned pregnancies were associated with higher PBQ score and risk to impaired bonding (p = 0.001 and p = 0.004, respectively). EPDS showed a high prevalence of PPD (29.1%) and was not associated with any Studied variable. Probably, this high prevalence of probable PPD was due to the context of insecurity secondary to the pandemic. CONCLUSIONS: We observed an increase in the prevalence of probable PPD and unplanned pregnancies during the first 18 months of the pandemic, which were associated with worse scores in mother-infant bonding. The impaired bond can affect the future development of children born during this period.

Assessment of school readiness and the importance of executive functions for learning.

OBJECTIVE: Considering the importance of the beginning of the academic trajectory for children to reach their full development, this work aims to evaluate the school readiness of preschool-age children and identify which factors influence these results, in order to contribute to the proposition of strategies that allow improving the teaching-learning process and child development. METHODS: This is a cross-sectional, descriptive and analytical study with 443 preschool children belonging to the West Region Cohort (ROC Cohort), from the public school system of the city of São Paulo. School readiness was assessed by the International Development and Early Learning Assessment (IDELA) tool. Non-parametric techniques were used for the correlation analysis between IDELA scores and sociodemographic and socioeconomic conditions: Spearman's parametric correlation, Mann-Whitney and Kruskal-Wallis tests. RESULTS: The children's mean age was 69 months (standard deviation - SD=2.8; ranging from 55 to 72 months) and most of them came from families with low socioeconomic level. Most children showed adequate readiness in the overall score (65%) and in most domains, except for emergent literacy, in which most (56.9%) were classified as "emergent". The highest percentage of insufficiency was identified in executive functions (4.1%), which showed a correlation only with the caregiver's education. CONCLUSIONS: Children had adequate school readiness scores, except for emergent literacy, but the insufficiency in executive functions may compromise the future schooling of these children. Thus, pedagogical proposals should consider these aspects for learning and pediatricians need to reinforce the habit of reading and playing games to stimulate child development.

Gestational age acceleration is associated with epigenetic biomarkers of prenatal physiologic stress exposure.

BACKGROUND: Physiological maternal stress response, such as imbalance in the glucocorticoid pathway and immune system seems to be mediated by DNA methylation (DNAm) and might translate intrauterine stress exposures into phenotypic changes in a sex-specific manner. DNAm in specific sites can also predict newborn gestational age and gestational age acceleration (GAA). GAA occurs when the predicted biological age is higher than the chronological age. In adults, poor health outcomes related to this deviance are well documented and raise questions for the interpretation and prediction in early stages of life. Boys seem to be more vulnerable to intrauterine stress exposure than girls; however, the mechanisms of adaptive sex-specific responses are still unclear. We hypothesize that intrauterine stress exposure is associated with GAA and could be different in boys and girls if inflammatory or glucocorticoid pathways exposure is considered. RESULTS: Using the Western Region Birth Cohort (ROC-São Paulo, Brazil) (n = 83), we calculated DNAm age and GAA from cord blood samples. Two epigenetic risk scores were calculated as an indirect proxy for low-grade inflammation (i-ePGS) and for glucocorticoid exposure (GES). Multivariate linear regression models were applied to investigate associations of GAA with prenatal exposures. The i-ePGS and GES were included in different models with the same co-variates considering sex interactions. The first multivariate model investigating inflammatory exposure (adj. R2 = 0.31, p = < 0.001) showed that GAA was positively associated with i-ePGS (CI, 0.26-113.87, p = 0.049) and negative pregnancy-related feelings (CI, 0.04-0.48 p = 0.019). No sex interaction was observed. The second model investigating glucocorticoid exposure (adj. R2 = 0.32, p = < 0.001) showed that the higher was the GAA was associated with a lower the lower was the GES in girls (CI, 0.04-2.55, p = 0.044). In both models, maternal self-reported mental disorder was negatively associated with GAA. CONCLUSION: Prenatal epigenetic score of exposure to low-grade inflammatory was a predictor of GAA for both sexes. Glucocorticoid epigenetic score seems to be more important to GAA in girls. This study supports the evidence of sex-specificity in stress response, suggesting the glucocorticoid as a possible pathway adopted by girls to accelerate the maturation in an adverse condition.

Seroconversion in asymptomatic COVID-19 pediatric patients with rheumatic diseases of one tertiary referral hospital.

OBJECTIVES: To evaluate seroconverted asymptomatic COVID-19 in pediatric Autoimmune Rheumatic Diseases (ARDs) patients and to identify the risk factors related to contagion. METHODS: A cross-sectional study was conducted in March 2021, before vaccination of children and adolescents in Brazil, including 77 pediatric ARDs patients, followed at a tertiary hospital and 45 healthy controls, all of them without a previous diagnosis of COVID-19. Data was obtained by a questionnaire with demographic data, symptoms compatible with COVID-19 over the previous year, and contact with people with confirmed COVID-19. Patient's medical records were reviewed to access data regarding disease and current medications. A qualitative immunochromatographic SARS-CoV-2 test was performed on all participants. RESULTS: Patients and controls were similar in terms of female gender (70.1% vs. 57.8%, p = 0.173), age (14 vs. 13 years, p = 0.269) and SARS-CoV-2 positive serology (22% vs. 15.5%, p = 0.481). 80.5% of rheumatic patients were in use of immunosuppressive drugs: 27.3% of them used corticosteroids (33.3% in high doses), and 7.8% on immunobiologicals. No statistical differences were found between positive (n = 17) and negative serology (n = 60) patients regarding demographic/socioeconomic data, contact with people with confirmed COVID-19, use and number of immunosuppressive drugs, use and dose of corticosteroids, use of hydroxychloroquine and immunobiological drugs (p > 0.05). CONCLUSIONS: Pediatric rheumatic disease patients were infected at the same rate as healthy ones. Neither the underlying pathology nor its immunosuppressive treatment seemed to interfere with contagion risk.

A home visit-based early childhood stimulation programme in Brazil-a randomized controlled trial.

Home visiting programmes are increasingly recognized as one of the most effective interventions to improve child health and development in low-income settings. However, the best platforms to deliver such programmes remain unclear. We conducted a randomized controlled trial to test the relative effectiveness of child development agents (CDAs) and community health workers (CHWs) as two possible delivery platforms for early childhood development (ECD) focused home visiting intervention in São Paulo, Brazil. A total of 900 children aged 9-15 months were screened for potential study inclusion between January and March 2015. Children who did not attend crèches at enrolment were included in the trial. Children were randomly assigned to control or to receive biweekly home visits either through a CHW in the areas covered by the Brazilian Family Health Strategy (FHS) or by a newly hired cadre of CDAs in the areas not covered by the FHS. The primary study outcome was children's development (cognition, motor, language and social emotional skills) assessed after 12 months of intervention with the PRIDI and Caregiver-Reported Early Development Instruments tools. A total of 826 mother-child dyads were enrolled in the trial. In intention-to-treat analysis, neither intervention arm improved study outcomes. In per-protocol (PP) analysis, the CDA programme resulted in a 0.22 standard deviation increase in children's development (95% confidence interval [0.01-0.43]). The results presented in this study suggest that home visiting programmes have the potential to improve child development among poor urban families in Brazil. However, delivering home visiting interventions through already active CHWs may not be feasible in the Brazilian context and coordination across sectors is essential to effective ECD policies.

Breastfeeding, Physical Growth, and Cognitive Development.

BACKGROUND AND OBJECTIVES: Breastfeeding is an evidence-based recommendation for all countries, but breastfeeding rates have been declining in many middle-income settings. One reason behind this decline is the perception that breastfeeding may not be necessary in modern urban settings, where clean water is available and alternative foods are abundant. We investigate the importance of breastfeeding for early childhood development in the modern urban context of São Paulo, Brazil. METHODS: In our study, we used data from the ongoing prospective Western Region Birth cohort in São Paulo, Brazil. Children were recruited at birth and managed for 3 years. Durations of exclusive and mixed breastfeeding were our primary independent variables. Our secondary independent variable was an indicator for compliance with World Health Organization (WHO) breastfeeding recommendations. Our primary outcomes of interest were indicators of children's physical, cognitive, language, and social-emotional development at 3 years of age. Adjusted estimates and 95% confidence intervals were calculated by using linear and logistic regression. RESULTS: Complying with WHO recommendations to exclusively breastfeed for 6 months followed by complementary feeding until 2 years of age was associated with a 0.4-SD increase in overall child development (ß: .38; confidence limit = 0.23 to 0.53), a 0.6-SD increase in height-for-age z score (ß: .55; confidence limit = 0.31 to 0.79), and a 67% decrease in the odds of stunting (odds ratio = 0.33; 95% confidence interval = 0.20 to 0.54). CONCLUSIONS: Our results suggest that even in settings with easy access to complementary foods, complying with WHO breastfeeding recommendations is important for healthy physical growth and cognitive development.

Non-communicable diseases, sociodemographic vulnerability and the risk of mortality in hospitalised children and adolescents with COVID-19 in Brazil: a cross-sectional observational study.

OBJECTIVES: To analyse how previous comorbidities, ethnicity, regionality and socioeconomic development are associated with COVID-19 mortality in hospitalised children and adolescents. DESIGN: Cross-sectional observational study using publicly available data from the Brazilian Ministry of Health. SETTING: Nationwide. PARTICIPANTS: 5857 patients younger than 20 years old, all of them hospitalised with laboratory-confirmed COVID-19, from 1 January 2020 to 7 December 2020. MAIN OUTCOME MEASURE: We used multilevel mixed-effects generalised linear models to study in-hospital mortality, stratifying the analysis by age, region of the country, presence of non-communicable diseases, ethnicity and socioeconomic development. RESULTS: Individually, most of the included comorbidities were risk factors for mortality. Notably, asthma was a protective factor (OR 0.4, 95% CI 0.24 to 0.67). Having more than one comorbidity increased almost tenfold the odds of death (OR 9.67, 95% CI 6.89 to 13.57). Compared with white children, Indigenous, Pardo (mixed) and East Asian had significantly higher odds of mortality (OR 5.83, 95% CI 2.43 to 14.02; OR 1.93, 95% CI 1.48 to 2.51; OR 2.98, 95% CI 1.02 to 8.71, respectively). We also found a regional influence (higher mortality in the North-OR 3.4, 95% CI 2.48 to 4.65) and a socioeconomic association (lower mortality among children from more socioeconomically developed municipalities-OR 0.26, 95% CI 0.17 to 0.38) CONCLUSIONS: Besides the association with comorbidities, we found ethnic, regional and socioeconomic factors shaping the mortality of children hospitalised with COVID-19 in Brazil. Our findings identify risk groups among children that should be prioritised for public health measures, such as vaccination.

PEDIATRICIANS AFTER RESIDENCY: A SURVEY OF PERSONAL/PROFESSIONAL DATA AND ISSUES.

OBJECTIVE: To assess personal, professional, medical, and scientific educational characteristics and issues reported by pediatricians. METHODS: Cross-sectional study based on an online survey including 614 pediatricians who graduated in the last 15 years at a University Pediatric Department in Brazil. RESULTS: The response rate was 331/614(54%). The majority were females (82%), the median age was 33 years (27-40) and median years of pediatric practice was 5 (1-13). High workload (>60 hours/week) occurred in 25% and 47% earned ≥15 minimum wages/month. The most work-related issues reported were long working hours, poor social life and a sedentary lifestyle (>50%). Pediatricians were further divided into two groups, according to years of pediatric clinical practice: group 1 (≤5 years) and group 2 (>5 years). The median of overall satisfaction with pediatric residency [8(0-10) vs. 9 (4-10); p=0.002] was significantly reduced in group 1. The frequencies of workload >60 hours, work on pediatric ward and pediatric intensive care were significantly higher in the first group (p<0.05). Regarding main issues related to clinical practice in the last year, long working hours (73 vs. 53%; p<0.001), poor social life (75 vs. 62%; p=0.018) and harassment (23 vs. 4%; p=0.003) were significantly higher in the first group. CONCLUSIONS: Very early career pediatricians (≤5 years) reported higher workload, lower income, work-related issues and different location of pediatric practice compared to early career pediatricians (>5 years). The overall satisfaction with pediatric residency was good, however, reduced in very early career pediatricians.

Differences in children and adolescents with SARS-CoV-2 infection: a cohort study in a Brazilian tertiary referral hospital.

OBJECTIVES: To compare demographic/clinical/laboratory/treatments and outcomes among children and adolescents with laboratory-confirmed coronavirus disease 2019 (COVID-19). METHODS: This was a cross-sectional study that included patients diagnosed with pediatric COVID-19 (aged <18 years) between April 11, 2020 and April 22, 2021. During this period, 102/5,951 (1.7%) of all admissions occurred in neonates, children, and adolescents. Furthermore, 3,962 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection samples were processed in patients aged <18 years, and laboratory-confirmed COVID-19 occurred in 155 (4%) inpatients and outpatients. Six/155 pediatric patients were excluded from the study. Therefore, the final group included 149 children and adolescents (n=97 inpatients and 52 outpatients) with positive SARS-CoV-2 results. RESULTS: The frequencies of sore throat, anosmia, dysgeusia, headache, myalgia, nausea, lymphopenia, pre-existing chronic conditions, immunosuppressive conditions, and autoimmune diseases were significantly reduced in children and adolescents (p<0.05). Likewise, the frequencies of enoxaparin use (p=0.037), current immunosuppressant use (p=0.008), vasoactive agents (p=0.045), arterial hypotension (p<0.001), and shock (p=0.024) were significantly lower in children than in adolescents. Logistic regression analysis showed that adolescents with laboratory-confirmed COVID-19 had increased odds ratios (ORs) for sore throat (OR 13.054; 95% confidence interval [CI] 2.750-61.977; p=0.001), nausea (OR 8.875; 95% CI 1.660-47.446; p=0.011), and lymphopenia (OR 3.575; 95% CI 1.355-9.430; p=0.010), but also had less hospitalizations (OR 0.355; 95% CI 0.138-0.916; p=0.032). The additional logistic regression analysis on patients with preexisting chronic conditions (n=108) showed that death as an outcome was significantly associated with pediatric severe acute respiratory syndrome (SARS) (OR 22.300; 95% CI 2.341-212.421; p=0.007) and multisystem inflammatory syndrome in children (MIS-C) (OR 11.261; 95% CI 1.189-106. 581; p=0.035). CONCLUSIONS: Half of the laboratory-confirmed COVID-19 cases occurred in adolescents. Individuals belonging to this age group had an acute systemic involvement of SARS-CoV-2 infection. Pediatric SARS and MIS-C were the most important factors associated with the mortality rate in pediatric chronic conditions with COVID-19.

Inactivated trivalent influenza vaccination is associated with lower mortality among patients with COVID-19 in Brazil.

OBJECTIVE: To estimate associations between trivalent influenza vaccination and COVID-19 mortality as well as severe clinical outcomes among hospitalised patients. DESIGN: Retrospective observational study. SETTING: This study was conducted among hospitalised patients with COVID-19 in Brazil. PARTICIPANTS: We analysed all hospitalised patients with COVID-19 with available vaccination information captured in Brazil's national electronic respiratory infection data system between 1 January 2020 and 23 June 2020. MAIN OUTCOME MEASURES: The primary outcomes were age-specific mortality rates of hospitalised patients with COVID-19 with and without recent inactivated trivalent influenza vaccination. RESULTS: A total of 53 752 clinically confirmed COVID-19 cases were analysed. Controlling for health facility of treatment, comorbidities as well as an extensive range of sociodemographic factors, patients who received a recent influenza vaccine experienced on average 7% lower odds of needing intensive care treatment (95% CI 0.87 to 0.98), 17% lower odds of requiring invasive respiratory support (95% CI 0.77 to 0.88) and 16% lower odds of death (95% CI 0.78 to 0.90). Protective effects were larger when the vaccine was administered after onset of symptoms as well as among younger patients. CONCLUSION: Patients with COVID-19 with recent inactivated influenza vaccination experience significantly better health outcomes than non-vaccinated patients in Brazil. Beneficial off-target effects of influenza vaccination through trained innate immune responses seem plausible and need to be further explored. Large-scale promotion of influenza vaccines seems advisable, especially in populations at high risk for severe COVID-19 disease progression.

Survive and Thrive in Brazil: The Boa Vista Early Childhood Program: study protocol of a stepped-wedge, randomized controlled trial.

BACKGROUND: A growing body of evidence suggests that early life health and developmental outcomes can be improved through parental support programs. The objective of this project was to test the feasibility, impact, and relative cost-effectiveness of an adapted "Reach Up and Learn" program delivered through home-visiting programs as well as through center-based parenting groups on child health and development in the municipality of Boa Vista, Brazil. METHODS: A randomized, stepped-wedge design was used to roll out and evaluate the two parenting platforms in Boa Vista municipality. A total of 39 neighborhoods with a high Neighborhood Vulnerability Index were selected for the study. For the first phase of the program, nine neighborhoods were randomly selected for home visits, and two were randomly selected for the center-based parenting groups. In the second phase of the program, 10 neighborhoods were added to the home-visiting program, and eight were added to the center-based program. In the final phase of the program, the remaining 10 control areas will also be assigned to treatment. Study eligibility will be assessed through a baseline survey completed by all pregnant women in the 39 study areas. Pregnant women will be eligible to participate in the study if they are either classified as poor, were under age 20 years when they became pregnant, or if they indicate to have been exposed to domestic or sexual violence. To assess program impact, an endline survey will be conducted when children reach age 2 years. The primary study outcome is child development at age 2 years as measured by the PRIDI instrument. Secondary outcome will be infant mortality, which will be assessed linking municipal vital registration systems to the program rollout. DISCUSSION: This trial will assess the feasibility and impact of parenting programs rolled out at medium scale. The results from the trial should create evidence urgently needed for guiding Brazil's national Criança Feliz program as well as similar efforts in other countries. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT03386747. Registered on 13 December 2017. All items of the World Health Organization Trial Registration Data Set are available in this record.

Measuring early childhood development in Brazil: validation of the Caregiver Reported Early Development Instruments (CREDI).

OBJECTIVE: The present study aims to analyze the psychometric properties and general validity of the Caregiver Reported Early Development Instruments (CREDI) short form for the population-level assessment of early childhood development for Brazilian children under age 3. METHOD: The study analyzed the acceptability, test-retest reliability, internal consistency and discriminant validity of the CREDI short-form tool. The study also analyzed the concurrent validity of the CREDI with a direct observational measure (Inter-American Development Bank's Regional Project on Child Development Indicators; PRIDI). The full sample includes 1,265 Brazilian caregivers of children from 0 to 35 months (678 of which comprising an in-person sample and 587 an online sample). RESULTS: Results from qualitative interviews suggest overall high rates of acceptability. Most of the items showed adequate test-retest reliability, with an average agreement of 84%. Cronbach's alpha suggested adequate internal consistency/inter-item reliability (α>0.80) for the CREDI within each of the six age groups (0-5, 6-11, 12-17, 18-23, 24-29 and 30-35 months of age). Multivariate analyses of construct validity showed that a significant proportion of the variance in CREDI scores could be explained by child gender and family characteristics, most importantly caregiver-reported cognitive stimulation in the home (p<0.0001). Regarding concurrent validity, scores on the CREDI were significantly correlated with overall PRIDI scores within the in-person sample at r=0.46 (p<0.001). CONCLUSIONS: The results suggested that the CREDI short form is a valid, reliable, and acceptable measure of early childhood development for children under the age of 3 years in Brazil.

Profile of health professionals who completed a master's, doctoral, or post-doctoral degree in one Brazilian pediatric program.

OBJECTIVE: This study aimed to determine the personal and professional characteristics, and the physical, psychiatric/psychological, and professional issues that exist among master's-, doctoral-, and post-doctoral-level health professionals. METHODS: A cross-sectional, online, self-reported survey of 452 postgraduates who completed master's, doctoral, or post-doctoral degrees in one graduate program in pediatrics in São Paulo, Brazil, was conducted. RESULTS: The response rate was 47% (211/453). The majority of participants were women (78%) and physicians (74%), and the median age was 47 years (28-71). Master's, doctoral, and post-doctoral degrees were reported by 73%, 53%, and 3%, respectively. High workload (>40 hours/week) occurred in 59%, and 45% earned ≥15 minimum wages/month. At least one participation in scientific meeting in the past year was reported by 91%, and 79% had published their research. Thirty-nine percent served as a member of a faculty of an institution of higher learning. The data were analyzed by two age groups: participants aged ≤48 years (group 1) and participants aged >48 years (group 2). The median rating of overall satisfaction with the profession in the past year [8 (0-10) vs. 9 (1-10), p=0.0113]; workload >40 hours/week (53% vs. 68%, p=0.034); and ≥15 minimum wages/month (37% vs. 56%, p=0.0083) were significantly lower in group 1. Further analysis by gender revealed that the median rating of overall satisfaction with the profession in the past year [8 (0-10) vs. 9 (3-10), p=0.0015], workload >40 hours/week (53% vs. 83%, p=0.0002), and ≥15 minimum wages/month (37% vs. 74%, p=0.0001) were significantly lower in women compared with men. The median rating of overall satisfaction with the mentorship supervision provided was significantly higher among the women 10 (5-10) vs. 10 (2-10), p=0.0324]. CONCLUSIONS: The majority of master's-, doctoral-, and post-doctoral-level health professionals were women and physicians, and had published their thesis. Younger postgraduates and women reported low salaries, less likelihood of working >40 hours/week, and less overall satisfaction with their profession. Further longitudinal and qualitative studies are warranted to assess career trajectories after graduation.

COMPLEXITY OF PEDIATRIC CHRONIC DISEASE: CROSS-SECTIONAL STUDY WITH 16,237 PATIENTS FOLLOWED BY MULTIPLE MEDICAL SPECIALTIES.

OBJECTIVE: To assess demographic data and characteristics of children and adolescents with pediatric chronic diseases (PCD), according to the number of specialties/patient. METHODS: We performed a cross-sectional study with 16,237 PCD patients at outpatient clinics in one year. Data were analyzed by an electronic data system, according to the number of physician appointments for PCD. This study assessed: demographic data, follow-up characteristics, types of medical specialty, diagnosis (International Statistical Classification of Diseases and Related Health Problems - ICD-10), number of day hospital clinic visits, and acute complications. RESULTS: Patients followed by ≥3 specialties simultaneously showed a significantly higher duration of follow-up compared to those followed by ≤2 specialties [2.1 (0.4-16.4) vs. 1.4 (0.1-16.2) years; p<0.001] and a higher number of appointments in all specialties. The most prevalent medical areas in patients followed by ≥3 specialties were: Psychiatry (Odds Ratio - OR=8.0; confidence interval of 95% - 95%CI 6-10.7; p<0.001), Palliative/Pain Care (OR=7.4; 95%CI 5.7-9.7; p<0.001), Infectious Disease (OR=7.0; 95%CI 6.4-7.8; p<0.001) and Nutrology (OR=6.9; 95%CI 5.6-8.4; p<0.001). Logistic regressions demonstrated that PCD patients followed by ≥3 specialties were associated with high risk for: number of appointments/patient (OR=9.2; 95%CI 8.0-10.5; p<0.001), day hospital clinic visits (OR=4.8; 95%CI 3.8-5.9; p<0.001), emergency department visits (OR=3.2; 95%CI 2.9-3.5; p<0.001), hospitalizations (OR=3.0; 95%CI 2.7-3.3; p<0.001), intensive care admissions (OR=2.5; 95%CI 2.1-3.0; p<0.001), and deaths (OR=2.8; 95%CI 1.9-4.0; p<0.001). The diagnosis of asthma, obesity, chronic pain, and transplant was significantly higher in patients followed by ≥3 specialties. CONCLUSIONS: The present study showed that PCD patients who required simultaneous care from multiple medical specialties had complex and severe diseases, with specific diagnoses.

Assessment of school readiness and the importance of executive functions for learning / Avaliação da prontidão escolar e a importância das funções executivas para o aprendizado

ABSTRACT Objective: Considering the importance of the beginning of the academic trajectory for children to reach their full development, this work aims to evaluate the school readiness of preschool-age children and identify which factors influence these results, in order to contribute to the proposition of strategies that allow improving the teaching-learning process and child development. Methods: This is a cross-sectional, descriptive and analytical study with 443 preschool children belonging to the West Region Cohort (ROC Cohort), from the public school system of the city of São Paulo. School readiness was assessed by the International Development and Early Learning Assessment (IDELA) tool. Non-parametric techniques were used for the correlation analysis between IDELA scores and sociodemographic and socioeconomic conditions: Spearman's parametric correlation, Mann-Whitney and Kruskal-Wallis tests. Results: The children's mean age was 69 months (standard deviation — SD=2.8; ranging from 55 to 72 months) and most of them came from families with low socioeconomic level. Most children showed adequate readiness in the overall score (65%) and in most domains, except for emergent literacy, in which most (56.9%) were classified as "emergent". The highest percentage of insufficiency was identified in executive functions (4.1%), which showed a correlation only with the caregiver's education. Conclusions: Children had adequate school readiness scores, except for emergent literacy, but the insufficiency in executive functions may compromise the future schooling of these children. Thus, pedagogical proposals should consider these aspects for learning and pediatricians need to reinforce the habit of reading and playing games to stimulate child development.

RESUMO Objetivo: Considerando-se a importância do início da trajetória acadêmica para as crianças alcançarem o seu pleno potencial de desenvolvimento, este trabalho tem como objetivo avaliar a prontidão escolar de crianças em idade pré-escolar e identificar que fatores influenciam esses resultados, com a finalidade de propor estratégias que possam melhorar o processo de ensino-aprendizagem e o desenvolvimento da criança. Métodos: Trata-se de um estudo transversal, descritivo e analítico, com 443 pré-escolares pertencentes à Coorte da Região Oeste (Coorte ROC) da rede pública de ensino da cidade de São Paulo. A prontidão escolar foi avaliada pela ferramenta International Development and Early Learning Assessment (IDELA). Técnicas não paramétricas foram utilizadas para a análise de correlação entre escores de IDELA e as condições sociodemográficas e socioeconômicas: correlação paramétrica de Spearman, testes de Mann-Whitney e Kruskal-Wallis. Resultados: A média de idade das crianças foi de 69 meses (desvio padrão — DP=2,8; variando de 55 a 72 meses) e maioria era proveniente de famílias com baixo nível socioeconômico. A maioria das crianças apresentou prontidão adequada na pontuação geral (65%) e na maior parte dos domínios, com exceção da pré-escrita, na qual as crianças foram predominantemente (56,9%) classificadas como "emergentes". O maior percentual de insuficiência foi identificado nas funções executivas (4,1%), apresentando correlação apenas com a formação do cuidador. Conclusões: As crianças apresentaram escores adequados de prontidão escolar, exceto para a pré-escrita, mas a insuficiência nas funções executivas pode comprometer a escolaridade futura dessas crianças. Assim, as propostas pedagógicas devem considerar esses aspectos para a aprendizagem, e os pediatras precisam reforçar o hábito de ler e dos jogos e brincadeiras para estimular o desenvolvimento infantil.

Mortality in adolescents and young adults with chronic diseases during 16 years: a study in a Latin American tertiary hospital.

OBJECTIVES: To evaluate mortality in adolescents and young adult patients with chronic diseases followed in a Latin American tertiary hospital. METHODS: A cross-sectional retrospective study was performed in a tertiary/academic hospital in the state of São Paulo, Brazil. Death occurred in 529/2850 (18.5%) adolescents and young adult patients with chronic diseases, and 25/529 (4.7%) were excluded due to incomplete medical charts. Therefore, 504 deaths were evaluated. RESULTS: Deaths occurred in 316/504 (63%) of early adolescent patients and in 188/504 (37%) of late adolescent/young adult patients. Further comparisons between early adolescents (n=316) and late adolescent/young adult patients (n=188) with pediatric chronic diseases at the last hospitalization showed that the median disease duration (22.0 [0-173] vs. 43.0 [0-227] months, p<0.001) was significantly lower in early adolescents vs. late adolescent/young adult patients. The median number of previous hospitalizations was significantly lower in the former group (4.0 [1-45] vs. 6.0 [1-52], p<0.001), whereas the last hospitalization in intensive care unit was significantly higher (60% vs. 47%, p=0.003). Regarding supportive measures, palliative care was significantly lower in the younger group compared to the older group (33% vs. 43%, p=0.02). The frequencies of renal replacement therapy (22% vs. 13%, p=0.02), vasoactive agents (65% vs. 54%, p=0.01), and transfusion of blood products (75% vs. 66%, p=0.03) were significantly higher in the younger group. The five most important etiologies of pediatric chronic diseases were: neoplasias (54.2%), hepatic diseases/transplantation (10%), human immunodeficiency virus (5.9%), and childhood-onset systemic lupus erythematosus and juvenile idiopathic arthritis (4.9%). Autopsy was performed in 58/504 (11%), and discordance between clinical and postmortem diagnoses was evidenced in 24/58 (41.3%). CONCLUSIONS: Almost 20% of deaths occurred in adolescents and young adults with distinct supportive care and severe disease patterns. Discordance between clinical diagnosis and autopsy was frequently observed.

Clinical indicators of child development in the capitals of nine Brazilian states: the influence of regional cultural factors.

OBJECTIVE: Evaluating the interaction between mother or caregiver and infant through the Clinical Indicators of Risks in Infant Development and investigating whether local and cultural influences during infant development affect these clinical indicators. INTRODUCTION: The Clinical Indicators of Risks in Infant Development was created in order to fully assess infants' development and the subjective relationship between the babies and their caregivers. The absence of two or more Clinical Indicators of Risks in Infant Developments suggests a possibly inadequate mental development. Given the continental size of Brazil and its accentuated cultural differences, one might question how trustworthy these indicators can be when applied to each of the geographical regions of the country. METHODS: This was a cross-sectional study with 737 infants from the capitals of 9 Brazilian states. The size of the initial sample population was based on a pilot study carried out in the cities of São Paulo and Brasília. The ages of children were grouped: 0-3 months, 4-7 months, 8-11 months and 12-18 months. The chi-square test was used together with analyses by the statistical software SPSS 13.0. RESULTS: Statistical analysis of results from the different municipalities against the total sample did not reveal any statistically significant differences. Municipalities represented were Belém (p=0.486), Brasília (p=0.371), Porto Alegre (p=0.987), Fortaleza (p=0.259), Recife (p=0.630), Salvador (0.370), São Paulo (p=0.238), Curitiba (p=0.870), and Rio de Janeiro (p= 0.06). DISCUSSION: Care for mental development should be considered a public health issue. Its evaluation and follow-up should be part of the already available mother-child assistance programs, which would then be considered to provide "full" care to children. CONCLUSIONS: Local habits and culture did not affect the results of the Clinical Indicators of Risks in Infant Development indicators. Clinical Indicators of Risks in Infant Development proved to be robust despite the specificities of each region.
