RESUMO
OBJECTIVE: Behavioral performance of health professionals is essential for adequate patient care. This study aimed to assess the behavioral skills of fellows in neonatology before and after a simulation training program on neonatal resuscitation. STUDY DESIGN: From March 2019 to February 2020, a prospective cohort with 12 second-year fellows in neonatology were evaluated during three training cycles (16 hours each) in manikin-based simulation of neonatal resuscitation with standardized scenarios. Each cycle lasted 1 month, followed by a 3-month interval. One video-recorded scenario of approximately 10 minutes was performed for each fellow at the beginning and at the end of each training cycle. Therefore, each fellow was recorded six times, before and after each one of three training cycles. Anxiety of the fellows was assessed by the Beck Anxiety Inventory applied before the first training cycle. The videos were independently analyzed in a random order by three trained facilitators using the Behavioral Assessment Tool. The behavioral performance was evaluated by repeated measures of analysis of variance adjusted for anxiety and for previous experience in neonatal resuscitation. RESULTS: Fellows' overall behavioral performance improved comparing the moment before the first training and after the second training. The specific skills, such as communication with the team, delegation of tasks, allocation of attention, use of information, use of resources, and professional posture, showed a significant improvement after the second month of training. No further gains were noted with the third training cycle. Anxiety was observed in 42% of the fellows and its presence worsened their behavioral performance. CONCLUSION: An improvement in behavioral performance was observed, comparing the moment before the first training and after the second training, without further gains after the third training. It is worth noting the important role of anxiety as a modulator of acquisition and retention of behavioral skills in health professionals in training. KEY POINTS: · Simulation training should improve technical and behavioral skills of providers. · Behavioral skills improve after a first cycle of training, but not after a repeat cycle. · Anxiety modulates trainees' behavioral performance.
RESUMO
BACKGROUND: Population-based studies analyzing neonatal deaths in middle-income countries may contribute to design interventions to achieve the Sustainable Development Goals, established by United Nations. This study goal is to analyze the annual trend of neonatal mortality in São Paulo State, Brazil, over a 10-year period and its underlying causes and to identify maternal and neonatal characteristics at birth associated with neonatal mortality. METHOD: A population-based study of births and deaths from 0 to 27 days between 2004 and 2013 in São Paulo State, Brazil, was performed. The annual trend of neonatal mortality rate according to gestational age was analyzed by Poisson or by Negative Binomial Regression models. Basic causes of neonatal death were classified according to ICD-10. Association of maternal demographic variables (block 1), prenatal and delivery care variables (block 2), and neonatal characteristics at birth (block 3) with neonatal mortality was evaluated by Poisson regression analysis adjusted by year of birth. RESULTS: Among 6,056,883 live births in São Paulo State during the study period, 48,309 died from 0 to 27 days (neonatal mortality rate: 8.0/1,000 live births). For the whole group and for infants with gestational age 22-27, 28-31, 32-36, 37-41 and ≥ 42 weeks, reduction of neonatal mortality rate was, respectively, 18 %, 15 %, 38 %, 53 %, 31 %, and 58 %. Median time until 50 % of deaths occurred was 3 days. Main basic causes of death were respiratory disorders (25 %), malformations (20 %), infections (17 %), and perinatal asphyxia (7 %). Variables independently associated with neonatal deaths were maternal schooling, prenatal care, parity, newborn sex, 1st minute Apgar, and malformations. Cesarean delivery, compared to vaginal, was protective against neonatal mortality for infants at 22-31 weeks, but it was a risk factor for those with 32-41 weeks. CONCLUSIONS: Despite the significant decrease in neonatal mortality rate over the 10-year period in São Paulo State, improved access to qualified health care is needed in order to avoid preventable neonatal deaths and increase survival of infants that need more complex levels of assistance.

Moderate and late preterm newborns comprise around 85% of live births < 37 weeks gestation. Data on their neonatal mortality in middle-income countries is limited. This study aims to analyze the temporal trend, causes and timing of neonatal mortality of infants with 320/7-366/7 weeks gestation without congenital anomalies from 2004-2015 in the population of São Paulo State, Brazil. A database was built by deterministic linkage of birth and death certificates. Causes of death were classified by ICD-10 codes. Among 7,317,611 live births in the period, there were 545,606 infants with 320/7-366/7 weeks gestation without congenital anomalies, and 5782 of them died between 0 and 27 days. The neonatal mortality rate decreased from 16.4 in 2004 to 7.6 per thousand live births in 2015 (7.47% annual decrease by Prais-Winsten model). Perinatal asphyxia, respiratory disorders and infections were responsible, respectively, for 14%, 27% and 44% of the 5782 deaths. Median time to death was 24, 53 and 168 h, respectively, for perinatal asphyxia, respiratory disorders, and infections. Bottlenecks in perinatal health care are probably associated with the results that indicate the need for policies to reduce preventable neonatal deaths of moderate and late preterm infants in the most developed state of Brazil.
RESUMO
OBJECTIVE: Analyze factors associated with clinical complications during intra-hospital transport of neonatal intensive care unit (NICU) patients. METHODS: Prospective study of 641 infants submitted to 1197 intra-hospital transports at a public university NICU. Factors associated with clinical complications during intra-hospital transports were studied by multiple logistic regression analysis. RESULTS: Included infants had a mean gestational age of 35.1 ± 3.8 weeks and a birth weight of 2328 ± 906 g. Underline diseases were: malformations (71.9%), infections (7.6%), respiratory distress (4.1%) and others (16.4%). Patients were transported for surgical procedures (22.6%), magnetic resonance (10.6%), tomography imaging (20.9%), contrasted exams (18.2%), ultrasound (10.4%) and others (17.3%). Clinical complications occurred in 327 (27.3%) transports and were associated (odds ratio; 95% CI) with: central nervous system malformations (1.6; 95% CI 1.0-2.0); use of supplemental oxygen (4.0; 95% CI 2.8-5.6); mechanical ventilation (5.0; 95% CI 3.5-7.5); transport for surgeries (4.0; 95% CI 1.1-14.0) and duration of the transport longer than 120 min (1.6; 95% CI 1.1-2.4). CONCLUSIONS: Intra-hospital transports are associated with increased risk of clinical complications.

Background: In Brazil, secondary data for epidemiology are largely available. However, they are insufficiently prepared for use in research, even when it comes to structured data since they were often designed for other purposes. To date, few publications focus on the process of preparing secondary data. The present findings can help in orienting future research projects that are based on secondary data. Objective: Describe the steps in the process of ensuring the adequacy of a secondary data set for a specific use and to identify the challenges of this process. Methods: The present study is qualitative and reports methodological issues about secondary data use. The study material was comprised of 6,059,454 live births and 73,735 infant death records from 2004 to 2013 of children whose mothers resided in the State of São Paulo - Brazil. The challenges and description of the procedures to ensure data adequacy were undertaken in 6 steps: (1) problem understanding, (2) resource planning, (3) data understanding, (4) data preparation, (5) data validation and (6) data distribution. For each step, procedures, and challenges encountered, and the actions to cope with them and partial results were described. To identify the most labor-intensive tasks in this process, the steps were assessed by adding the number of procedures, challenges, and coping actions. The highest values were assumed to indicate the most critical steps. Results: In total, 22 procedures and 23 actions were needed to deal with the 27 challenges encountered along the process of ensuring the adequacy of the study material for the intended use. The final product was an organized database for a historical cohort study suitable for the intended use. Data understanding and data preparation were identified as the most critical steps, accounting for about 70% of the challenges observed for data using. Conclusion: Significant challenges were encountered in the process of ensuring the adequacy of secondary health data for research use, mainly in the data understanding and data preparation steps. The use of the described steps to approach structured secondary data and the knowledge of the potential challenges along the process may contribute to planning health research.

OBJECTIVE: To analyse the accuracy and reproducibility of photogrammetry in detecting thoracic abnormalities in infants born prematurely. DESIGN: Cross-sectional study. SETTING: The Premature Clinic at the Federal University of São Paolo. PARTICIPANTS: Fifty-eight infants born prematurely in their first year of life. OUTCOME MEASURES: Measurement of the manubrium/acromion/trapezius angle (degrees) and the deepest thoracic retraction (cm). Digitised photographs were analysed by two blinded physiotherapists using a computer program (SAPO; http://SAPO.incubadora.fapesp.br) to detect shoulder elevation and thoracic retraction. Physical examinations performed independently by two physiotherapists were used to assess the accuracy of the new tool. RESULTS: Thoracic alterations were detected in 39 (67%) and in 40 (69%) infants by Physiotherapists 1 and 2, respectively (kappa coefficient=0.80). Using a receiver operating characteristic curve, measurement of the manubrium/acromion/trapezius angle and the deepest thoracic retraction indicated accuracy of 0.79 and 0.91, respectively. For measurement of the manubrium/acromion/trapezius angle, the Bland and Altman limits of agreement were -6.22 to 7.22° [mean difference (d)=0.5] for repeated measures by one physiotherapist, and -5.29 to 5.79° (d=0.75) between two physiotherapists. For thoracic retraction, the intra-rater limits of agreement were -0.14 to 0.18cm (d=0.02) and the inter-rater limits of agreement were -0.20 to -0.17cm (d=0.02). CONCLUSION: SAPO provided an accurate and reliable tool for the detection of thoracic abnormalities in preterm infants.

OBJETIVOS: avaliar se a complacência pulmonar precoce é fator preditor da presença de displasia broncopulmonar aos 28 dias de vida, em prematuros. MÉTODO: coorte prospectiva de neonatos com idade gestacional <32 semanas e peso ao nascer entre 500 e 1250 g, que receberam surfactante profilático com 30 minutos de vida. Com 60 minutos de vida, um pneumotacógrafo acoplado entre a cânula traqueal e o circuito do respirador mediu, através do WinTracer®, o fluxo de gases e os gradientes de pressão, obtendo-se valores de complacência pulmonar e resistência das vias aéreas. Procedeu-se à regressão logística dos fatores associados à presença de dependência de oxigênio e/ou ventilação aos 28 dias de vida. RESULTADOS: dos 32 recém-nascidos inicialmente avaliados, 25 sobreviveram até 28 dias, quando 17 (68 por cento) eram dependentes de oxigênio e/ou de ventilação assistida (Grupo 1) e oito (32 por cento) não (Grupo 2). O Grupo 1 apresentava idade gestacional mais baixa, índice de gravidade clínica mais elevado e maior freqüência de persistência do canal arterial. A complacência pulmonar e a resistência de vias aéreas foi similar nos dois grupos. Na regressão logística, a persistência do canal arterial e a idade gestacional foram preditores para displasia. CONCLUSÕES: a complacência pulmonar na primeira hora de vida não foi fator preditor da presença de displasia broncopulmonar na população analisada.
OBJECTIVES: to evaluate whether early pulmonary compliance could be a predictor of the presence of bronchopulmonary dysplasia at 28 days of life in preterm infants. METHODS: a cohort study was carried out involving neonates with gestational age <32 weeks and a birth weight of 500-1250 g receiving prophylactic surfactant at 30 minutes of life. The lung mechanics was evaluated using a pneumotachograph connected to the ventilator circuit 60 minutes after birth. Flow signals and volume were measured using WinTracer® in order to determine the dynamic pulmonary compliance and the airway resistance. Variables associated with the need for oxygen or assisted ventilation at 28 days were assessed using logistic regression. RESULTS: 32 neonates were enrolled in the study and 25 survived until the 28th day, at which point 17 (68 percent) needed assisted ventilation and/or oxygen (Group 1), and 8 did not (Group 2). The Group 1 infants were younger, had higher clinical risk index scores and frequency of patent ductus arteriosus. The lung mechanics in the 1st hour of life was similar in Groups 1 and 2. Regression analysis showed that bronchopulmonary dysplasia was associated with the presence of patent ductus arteriosus and lower gestational age. CONCLUSIONS: pulmonary compliance figures in the 1st hour of life did not predict the presence of bronchopulmonary dysplasia in the 28th day of life of the studied population.
