Early Growth and Neurologic Outcomes of Infants with Probable Congenital Zika Virus Syndrome.

We report the early growth and neurologic findings of 48 infants in Brazil diagnosed with probable congenital Zika virus syndrome and followed to age 1-8 months. Most of these infants had microcephaly (86.7%) and craniofacial disproportion (95.8%). The clinical pattern included poor head growth with increasingly negative z-scores, pyramidal/extrapyramidal symptoms, and epilepsy.

Effect of maternal skin-to-skin contact on decolonization of Methicillin-Oxacillin-Resistant Staphylococcus in neonatal intensive care units: a randomized controlled trial.

BACKGROUND: Decolonization with topical antibiotics is necessary to control outbreaks of multidrug-resistant bacterial infection in the Neonatal Intensive Care Unit (NICU), but can trigger bacterial resistance. The objective of this study was to determine whether skin-to-skin contact of newborns colonized with Methicillin-Oxacillin Resistant Staphylococcus aureus or Methicillin-Oxacillin-Resistant Coagulase-Negative Staphylococcus aureus (MRSA/MRSE) with their mothers could be an effective alternative to promote bacterial decolonization of newborns' nostrils. METHODS: We performed a randomized clinical trial with 102 newborns admitted to the NICU in three hospitals in São Luís, Brazil. Inclusion criteria were birth weight of 1300 to 1800 g, more than 4 days of hospitalization, newborns with positive nostril cultures for MRSA and/or multidrug-resistant coagulase-negative Staphylococcus and mothers not colonized by these bacteria. We used a random number algorithm for randomization. Allocation was performed using sealed opaque envelopes. Skin-to-skin contact was given twice a day for 60 minutes for seven consecutive days. The control group received routine care without skin-to-skin contact. There was no masking of newborn's mothers or researchers but the individuals who carried out bacterial cultures and assessed results were kept blind to group allocation. The primary outcome was colonization status of newborns' nostrils after 7 days of intervention. The directional hypothesis was that more newborns who receive skin-to-skin holding 2 hours/day for 7 days than newborns who receive normal care will be decolonized. RESULTS: Decolonization of MRSA/MRSE was greater in the intervention group (Risk Ratio = 2.27; 95% CI 1.27-4.07, p-value = 0.003). Number Needed to Treat (NNT) was 4.0 (95% CI 2.2 - 9.4). After adjustment for the possible confounding effects of small for gestational age birth, antibiotic use, need for resuscitation, sex and cesarean delivery, skin-to-skin contact remained strongly associated with decolonization of newborns' nostrils from MRSA/MRSE bacteria (p = 0.007). There was no need to interrupt the trial for safety reasons. CONCLUSION: Skin-to-skin contact might be an effective and safe method for promoting decolonization of newborns' nostrils colonized by MRSA/MRSE. TRIAL REGISTRATION: The study was registered with ClinicalTrials.gov ( NCT01498133 , November 21, 2011).

Factors associated with skin-to-skin contact less than 180 min/day in newborns weighing up to 1,800 g: multicenter study.

This article aims to evaluate the factors associated with a skin-to-skin contact time <180 min/day in newborns weighing up to 1,800 g during neonatal hospitalization. Prospective observational cohort study conducted in neonatal units of reference for the Kangaroo Method in Brazil. Data from 405 dyads (mother/child) were analyzed from May 2018 to March 2020. Maternal and neonatal explanatory variables were collected from medical records and interviews. Skin-to-skin contact was recorded in forms posted at the bedside, filled out by parents and staff. The outcome variable was the mean time of skin-to-skin contact < 180 min/day. Hierarchical modeling was performed by Poisson regression with robust variance. The variables associated with the outcome were "without easy access to the hospital", "without previous knowledge of the kangaroo method" and "having had morbidities during pregnancy". Mothers without easy access to the hospital and who are unaware of the kangaroo method should be priority targets for health policies to develop strategies that promote greater exposure to skin-to-skin contact during the hospitalization period of their children.

Perinatal and early life factors associated with symptoms of depression in Brazilian children.

BACKGROUND: Few studies have been conducted on the association between perinatal and early life factors with childhood depression and results are conflicting. Our aim was to estimate the prevalence and perinatal and early life factors associated with symptoms of depression in children aged 7 to 11 years from two Brazilian birth cohorts. METHODS: The study was conducted on 1444 children whose data were collected at birth and at school age, in 1994 and 2004/2005 in Ribeirao Preto, where they were aged 10-11 years and in 1997/98 and 2005/06 in São Luís, where children were aged 7-9 years. Depressive symptoms were investigated with the Child Depression Inventory(CDI), categorized as yes (score ≥ 20) and no (score < 20). Adjusted and non-adjusted prevalence ratios (PR) were estimated by Poisson regression with robust estimation of the standard errors. RESULTS: The prevalence of depressive symptoms was 3.9% (95%CI = 2.5-5.4) in Ribeirão Preto and 13.7% (95%CI = 11.0-16.4) in São Luís. In the adjusted analysis, in Ribeirão Preto, low birth weight (PR = 3.98; 95%CI = 1.72-9.23), skilled and semi-skilled manual occupation (PR = 5.30; 95%CI = 1.14-24.76) and unskilled manual occupation and unemployment (PR = 6.65; 95%CI = 1.16-38.03) of the household head were risk factors for depressive symptoms. In São Luís, maternal schooling of 0-4 years (PR = 2.39; 95%CI = 1.31-4.34) and of 5 to 8 years (PR = 1.80; 95%CI = 1.08-3.01), and paternal age <20 years (PR = 1.92; 95%CI = 1.02-3.61), were independent risk factors for depressive symptoms. CONCLUSIONS: The prevalence of depressive symptoms was much higher in the less developed city, São Luís, than in the more developed city, Ribeirão Preto, and than those reported in several international studies. Low socioeconomic level was associated with depressive symptoms in both cohorts. Low paternal age was a risk factor for depressive symptoms in the less developed city, São Luís, whereas low birth weight was a risk factor for depressive symptoms in the more developed city, Ribeirão Preto.

Skin-to-skin contact and deaths in newborns weighing up to 1800 grams: a cohort study.

OBJECTIVE: To evaluate the association between dose of skin-to-skin contact (SSC) per day and initiation time with the occurrence of deaths in newborns with weight up to 1800g. METHOD: Multicentric cohort in five Brazilian neonatal units, including newborns with a birth weight of ≤1800g. The time of SSC was registered in individual file, by the team or family during the hospitalization. Maternal and newborn data were obtained through questionnaires applied to mothers and in medical records. Classification Tree was used for data analysis. RESULTS: The performance of the first SSC after 206h was significantly associated with death (p = 0.02). Although there was no association between SSC/day and death (p = 0.09), the number of deaths among those who performed more than 146.9 minutes/day was lower (3;1.5%) than among those who performed this practice for a shorter time (13;6.4%), a fact considered of great clinical importance. Early and late infections present statistically significant associations with the outcome. The chance of death was equal to zero when there was no early infection in the group with the longest duration of SSC. This probability was also equal to zero in the absence of late sepsis for the group with less than 146.9 minutes/day of SSC. CONCLUSIONS: The first SSC before 206 hours of life is recommended in order to observe a reduction in the risk of neonatal death. Staying in SSC for more than 146.9 min/day seems to be clinically beneficial for these neonates mostly when it was associated with the absence of infection.

The role of skin-to-skin contact in exclusive breastfeeding: a cohort study.

OBJETIVE: To understand the role of exposure to skin-to-skin contact and its minimum duration in determining exclusive breastfeeding at hospital discharge in infants weighing up to 1,800g at birth. METHODS: A multicenter cohort study was carried out in five Brazilian neonatal units. Infants weighing ≤ 1,800g at birth were eligible. Skin-to-skin contact time was recorded by the health care team and parents on an individual chart. Maternal and infant data was obtained from maternal questionnaires and medical records. The Classification Tree, a machine learning method, was used for data analysis; the tree growth algorithm, using statistical tests, partitions the dataset into mutually exclusive subsets that best describe the response variable and calculates appropriate cut-off points for continuous variables, thus generating an efficient explanatory model for the outcome under study. RESULTS: A total of 388 infants participated in the study, with a median of 31.6 (IQR = 29-31.8) weeks of gestation age and birth weight of 1,429g (IQR = 1,202-1,610). The exclusive breastfeeding rate at discharge was 61.6%. For infant's weighting between 1,125g and 1,655g, exposed to skin-to-skin contact was strongly associated with exclusive breastfeeding. Moreover, infants who made an average > 149.6 min/day of skin-to-skin contact had higher chances in this outcome (74% versus 46%). In this group, those who received a severity score (SNAPPE-II) equal to zero increased their chances of breastfeeding (83% versus 63%). CONCLUSION: Skin-to-skin contact proved to be of great relevance in maintaining exclusive breastfeeding at hospital discharge for preterm infants weighing 1,125g-1,655g at birth, especially in those with lower severity scores.

Sex-Specific Effects of Nutritional Supplements for Infants Born Early or Small: An Individual Participant Data Meta-Analysis (ESSENCE IPD-MA) I-Cognitive Function and Metabolic Risk.

Neonatal nutritional supplements are widely used to improve growth and development but may increase risk of later metabolic disease, and effects may differ by sex. We assessed effects of supplements on later development and metabolism. We searched databases and clinical trials registers up to April 2019. Participant-level data from randomised trials were included if the intention was to increase macronutrient intake to improve growth or development of infants born preterm or small-for-gestational-age. Co-primary outcomes were cognitive impairment and metabolic risk. Supplementation did not alter cognitive impairment in toddlers (13 trials, n = 1410; adjusted relative risk (aRR) 0.88 [95% CI 0.68, 1.13]; p = 0.31) or older ages, nor alter metabolic risk beyond 3 years (5 trials, n = 438; aRR 0.94 [0.76, 1.17]; p = 0.59). However, supplementation reduced motor impairment in toddlers (13 trials, n = 1406; aRR 0.76 [0.60, 0.97]; p = 0.03), and improved motor scores overall (13 trials, n = 1406; adjusted mean difference 1.57 [0.14, 2.99]; p = 0.03) and in girls not boys (p = 0.03 for interaction). Supplementation lowered triglyceride concentrations but did not affect other metabolic outcomes (high-density and low-density lipoproteins, cholesterol, fasting glucose, blood pressure, body mass index). Macronutrient supplementation for infants born small may not alter later cognitive function or metabolic risk, but may improve early motor function, especially for girls.

Sex-Specific Effects of Nutritional Supplements for Infants Born Early or Small: An Individual Participant Data Meta-Analysis (ESSENCE IPD-MA) II: Growth.

Neonatal nutritional supplements may improve early growth for infants born small, but effects on long-term growth are unclear and may differ by sex. We assessed the effects of early macronutrient supplements on later growth. We searched databases and clinical trials registers from inception to April 2019. Participant-level data from randomised trials were included if the intention was to increase macronutrient intake to improve growth or development of infants born preterm or small-for-gestational-age. Co-primary outcomes were cognitive impairment and metabolic risk. Supplementation did not alter BMI in childhood (kg/m2: adjusted mean difference (aMD) -0.11[95% CI -0.47, 0.25], p = 0.54; 3 trials, n = 333). Supplementation increased length (cm: aMD 0.37[0.01, 0.72], p = 0.04; 18 trials, n = 2008) and bone mineral content (g: aMD 10.22[0.52, 19.92], p = 0.04; 6 trials, n = 313) in infancy, but not at older ages. There were no differences between supplemented and unsupplemented groups for other outcomes. In subgroup analysis, supplementation increased the height z-score in male toddlers (aMD 0.20[0.02, 0.37], p = 0.03; 10 trials, n = 595) but not in females, and no significant sex interaction was observed (p = 0.21). Macronutrient supplementation for infants born small may not alter BMI in childhood. Supplementation increased growth in infancy, but these effects did not persist in later life. The effects did not differ between boys and girls.

Care for healthy newborns in Brazil: are we making progress in achieving best practices? / Atenção hospitalar ao recém-nascido saudável no Brasil: estamos avançando na garantia das boas práticas?

This paper aims to compare best practices for healthy newborns in public and mixed hospitals affiliated with SUS, according to type of birth, between "Nascer no Brasil/2011" (NB - Birth in Brazil) and in the last assessment cycle of Rede Cegonha, here called "Avaliação da Rede Cegonha/2017" (ARC - Stork Network Assessment). NB included a sample with national representativeness of 266 hospitals, and ARC was conducted in 606 maternity hospitals included in the Rede Cegonha strategy, totaling 15,994 and 8,047 pairs of healthy mothers and newborns, respectively.Between the two studies, NB-2011 and ARC-2017, although the proportion of cesarean sections remained around 44%, the prevalence of skin-to-skin contact with newborns, breastfeeding in the delivery room and breastfeeding in the first 24h of life increased by 140%, 82% and 6%, respectively. The proportion of upper airway aspiration of newborns dropped 65%. The results indicate that the use of evidence-based guidelines for the care of healthy newborns has increased in clinical practice, considering the six-year period between the compared studies. Despite the progress, important challenges remain to ensure best practices for all women and newborns, especially in relation to cesarean births.

O artigo tem como objetivo comparar práticas do cuidado ao recém-nascido saudável no momento do nascimento em hospitais públicos e mistos conveniados ao SUS, segundo o tipo de parto, verificadas na pesquisa "Nascer no Brasil/2011" (NB) e no último ciclo avaliativo da RC, aqui denominada "Avaliação da Rede Cegonha/2017" (ARC). O NB incluiu uma amostra com representatividade nacional de 266 hospitais e a ARC foi conduzida em 606 maternidades inseridas na estratégia Rede Cegonha, totalizando 15.994 e 8.047 pares de puérperas e recém-nascidos saudáveis, respectivamente. Entre os dois estudos, NB-2011 e ARC-2017, embora a proporção de cesariana tenha se mantido em torno de 44%, a prevalência do contato pele a pele com o RN, da amamentação na sala de parto e nas primeiras 24h de vida aumentaram, 140%, 82% e 6%, respectivamente. Já a proporção de aspiração de vias aéreas superiores do RN, caiu 65%. Os resultados indicam que o uso de diretrizes baseadas em evidências para o cuidado de recém-nascidos saudáveis aumentou na prática clínica, considerando o período de seis anos entre os estudos comparados. Apesar desse progresso, permanecem importantes desafios para garantir as melhores práticas para a totalidade de mulheres e recém-nascidos, principalmente em relação aos partos cesáreos.

Evaluation of the birthplace of newborns with gestational age less than 34 weeks according to the complexity of the Neonatal Unit in maternity hospitals linked to the "Rede Cegonha": Brazil, 2016-2017. / Avaliação do local de nascimento de recém-natos com idade gestacional inferior a 34 semanas segundo complexidade da Unidade Neonatal em maternidades vinculadas à Rede Cegonha: Brasil, 2016-2017.

This study aims to evaluate the birthplace of preterm infants with less than 34 gestational weeks at birth by type of neonatal care service in maternity hospitals of the "Rede Cegonha" and estimate the maternal factors associated with the inadequate place of birth for gestational age. This national cross-sectional study was performed in 2016/2017 to evaluate health establishments with the Rede Cegonha's action plan. Information was analyzed from 303 puerperae and the respective health establishments of their births. Newborns were classified by gestational age at birth (<30 and 30-33 weeks) and health establishments as hospitals with neonatal intensive care service, hospitals with intermediate neonatal care service, and hospitals without neonatal care service. Ministerial Ordinance N° 930/2012 was used to classify the birthplace as appropriate for the newborn's gestational age. Preterm birth prevalence was 37.3 at less than 30 weeks' gestation and 66.8 at 30-33 weeks. Birth in inappropriate services for the newborn's gestational age occurred in 6.3%, with significant regional and social differences. Inequalities in access to neonatal care for preterm infants persist in the "Rede Cegonha" despite advances.

O objetivo deste estudo é avaliar o local de nascimento dos prematuros com menos de 34 semanas gestacionais segundo tipo de serviço de assistência neonatal em maternidades da Rede Cegonha, bem como estimar os fatores maternos associados ao local de nascimento não apropriado para idade gestacional. Estudo seccional, de âmbito nacional, realizado em 2016/2017, para avaliação de estabelecimentos com plano de ação da Rede Cegonha. Foram analisadas informações de 303 puérperas e os respectivos locais de ocorrência do parto. Os recém-natos foram classificados segundo a idade gestacional ao nascer (< 30 e 30 a 33 semanas) e os serviços de saúde como unidade de cuidados intensivos neonatais, cuidados intermediários, sem serviço de cuidados neonatais. A portaria ministerial nº 930/2012 foi utilizada para classificar o local de nascimento como apropriado para a idade gestacional do recém-nato. A prevalência de nascimento pré-termo com menos de 30 semanas gestacional foi 37,3 e entre 30 e 33 semanas de 66,8. O nascimento em serviços não apropriado para a idade gestacional do recém-nascido ocorreu em 6,3%, com importantes diferenças regionais e sociais. Apesar dos avanços ainda persistem inequidades no acesso aos cuidados neonatais de prematuros na Rede Cegonha.

Neonatal bed status in Brazilian maternity hospitals: an exploratory analysis. / Situação dos leitos neonatais em maternidades brasileiras: uma análise exploratória.

Neonatal units should be organized as a progressive care line, with intermediate and intensive care beds (conventional and kangaroo). The aim of this study was to evaluate the status and adequacy of neonatal beds in maternity hospitals linked to the 'Stork Network' ("Rede Cegonha"). A descriptive study was conducted in 606 maternity hospitals in all regions of Brazil. The databases used belonged to the Stork Network Evaluation Survey and the National Live Birth System. To assess the distribution of neonatal beds by typology, the parameters proposed in Ordinance N. 930/2012 of the Ministry of Health were used. Most neonatal units are not organized as a progressive care line with the three types of bed planned. Kangaroo intermediate care beds comprise the minority of implanted beds. There is a concentration of intensive and intermediate beds in the Southeast and South regions, which show a kangaroo intermediate care bed deficit. Analyzing the adequacy of beds by the number of live births, one can observe an inadequacy of Kangaroo care beds in all regions of Brazil, as well as intensive bed deficit in the North and Northeast regions, and adequacy of conventional intermediate care beds in all regions.

As unidades neonatais devem ser organizadas como uma linha de cuidados progressivos com leitos de cuidado intensivo e intermediário (convencional e canguru). O objetivo deste estudo foi avaliar a situação e a adequação dos leitos neonatais em maternidades da Rede Cegonha. Estudo descritivo, realizado em 606 maternidades em todas as regiões do Brasil. Os bancos de dados utilizados foram os da Avaliação da Atenção ao Parto e Nascimento em Maternidades da Rede Cegonha e do Sistema Nacional de Nascidos Vivos. Para avaliar a distribuição de leitos neonatais por tipologia, foram utilizados os parâmetros propostos na Portaria GM/MS nº 930/2012. A minoria das unidades se organiza como uma linha de cuidados progressiva com as três tipologias de leito previstas (24,42%). Os leitos de cuidado intermediário Canguru são a minoria dos leitos implantados (11,27%). Há uma concentração de leitos intensivos e intermediários nas regiões Sudeste e Sul, que apresentam déficit de leitos de cuidado intermediário Canguru. Ao analisar a adequação dos leitos pelo número de nascidos vivos, verifica-se inadequação dos leitos de cuidado Canguru em todas as regiões do Brasil, déficit de leitos intensivos nas regiões Norte e Nordeste e adequação de leitos de cuidado intermediário convencional em todas as regiões.

Birth by cesarean delivery and central adiposity in adolescents from a birth cohort.

The aim of this study was to analyze the association between birth by cesarean section and central adiposity in adolescents in São Luís, Maranhão State, Brazil. This was a cohort study that included 601 participants evaluated at birth and at 18-19 years. At birth we assessed type of delivery, maternal education, family income, maternal marital status, maternal body mass index before pregnancy, prenatal care, maternal smoking habit, gestational age at delivery and intrauterine growth restriction. In the adolescents, we evaluated central adiposity using the dual X-ray energy absorptiometry method. The indicators of central fat used were the trunk-to-total fat mass ratio (T/T), the android-to-gynoid fat mass ratio (A/G), the trunk-to-limb fat mass ratio (T/Lb), and the trunk-to-leg fat mass ratio (T/Lg). A theoretical model for the study of associations was developed using directed acyclic graphs, which allowed selecting the variables that required minimum adjustment for inclusion in the predictive model of exposure to cesarean delivery. The data were analyzed with marginal structural models weighted by the inverse of the probability of selection. A total of 38.6% of the adolescents studied were delivered by cesarean section. There was no significant difference in the central adiposity of adolescents delivered by cesarean section according to the indicators used: T/T ( coefficient = -0.003; 95%CI: -0.013; 0.007), A/G (coefficient = 0.001; 95%CI: -0.015; 0.018); T/Lb (coefficient = -0.016; 95%CI: -0.048; 0.016); T/Lg (coefficient = 0.014; 95%CI: -0.060; 0.030). In conclusion, there was no association between cesarean section delivery and greater central adiposity in the studied adolescents.

Congenital Zika syndrome: association between the gestational trimester of maternal infection, severity of brain computed tomography findings and microcephaly at birth.

This study analyzed possible associations between the trimester of maternal Zika virus infection (ZIKV) in pregnancy, severity of brain computed tomography (CT) findings and the presence of microcephaly at birth in children with Congenital Zika Syndrome (CZS). It was an analytical study in a cohort of children with CZS. Symptoms of maternal infection were dichotomized into the 1st trimester of pregnancy and other trimesters. Head circumference (HC) at birth was used to calculate the z-score. Mild microcephaly was defined as HC between 2 and ≥3 standard deviations (SD) below the mean for each gestational age and sex, and severe microcephaly when HC <3 SD below average. Brain CT images were evaluated by two radiologists and classified, according to the severity, into mild, moderate and severe. Fisher's exact, Mann-Whitney and Kruskal-Wallis tests were used to verify the associations between variables. In 108 children, maternal infection in the 1st trimester of pregnancy was associated with more severe brain CT abnormalities (p=0.038), greater severity of microcephaly at birth (p=0.013) and lower HC z-scores at birth (p=0.021). The severity of brain CT lesions was also associated with lower HC z-scores at birth (p<0.001). Maternal ZIKV infection during the first trimester of pregnancy proved to be an important risk factor for a more severe spectrum of CZS, as it is associated with more severe brain CT abnormalities and, consequently, with lower HC z-scores at birth.

Mean birth weight among term newborns: direction, magnitude and associated factors.

A trend towards increasing birth weight has been shown, but factors that explain these trends have not been elucidated. The objectives of this study were to evaluate changes in mean birth weight of term newborns and to identify factors associated with them. All cohorts are population-based studies in which random samples of births (Ribeirão Preto, São Paulo State in 1978/1979, 1994 and 2010; Pelotas, Rio Grande do Sul State in 1982, 1993 and 2004; and São Luís, Maranhão State in 1997/1998 and 2010, Brazil). A total of 32,147 full-term, singleton live births were included. Mean birth weight reduced in the first study period (-89.1g in Ribeirão Preto from 1978/1979 to 1994, and -27.7g in Pelotas from 1982 to 1993) and increased +30.2g in Ribeirão Preto from 1994 to 2010 and +24.7g in São Luís from 1997 to 2010. In the first period, in Ribeirão Preto, mean birth weight reduction was steeper among mothers with high school education and among those born 39-41 weeks. In the second period, the increase in mean birth weight was steeper among mothers with low schooling in Ribeirão Preto and São Luís, females and those born 37-38 weeks in Ribeirão Preto and cesarean section in São Luís. Birth weight decreased in the first study period then increased thereafter. The variables that seem to have been able to explain these changes varied over time.

Skin-to-skin contact and late-onset sepsis in newborns weighing up to 1.800g: a cohort study / Contato pele a pele e sepse tardia em recém-nascidos com peso até 1.800g: estudo de coorte

Abstract Objectives: to evaluate the association between the time to initiate the first skin-to-skin contact (SSC) and the daily practice time with the rates of late-onset sepsis in newborns ≤1,800g. Methods: a multicentric cohort study was carried out at the neonatal units located in three Brazilian geographic regions. The SSC time was recorded in individual files by the hospital staff and the newborn's parents. Maternal and neonatal data were obtained from medical records and through questionnaires applied to the mothers. Data analysis was carried out using a tree algorithm classification, which divided the data set into mutually exclusive subsets that best described the variable response. Results: 405 newborns participated in the study, with an average of 31.3 ± 2.7 weeks and 1,412g (QR=1,164-1,605g) as a median birth weight. The first SSC was carried out within 137 hours of life (≤5.7 days) was associated with a lower rate of late sepsis (p=0.02) for newborns who underwent daily SSC of 112.5 to 174.7 min/day (1.9 to 2.9h/day), with a reduction in the sepsis rate from 39.3% to 27.5%. Furthermore, the duration of SSC >174.7min/day (>2.9h/day) was relevant (p<0.001) for newborns who weighed >1,344g, with a reduction in this rate from 24.1% to 6%. Conclusions: SSP has been proven to be significant in reducing late-onset sepsis rates in preterm newborns, especially when carried out in a timely manner (≤5.7 days) and prolonged (>2.9h/day).

Resumo Objetivos: avaliar a associação entre o tempo para iniciar o primeiro contato pele a pele (CPP) e o tempo diário praticado com a taxa de sepse tardia em recém-nascidos ≤1.800g. Métodos: coorte multicêntrica realizada em unidades neonatais de três regiões geográficas brasileiras. O CPP foi registrado em ficha individual pela equipe e pais do recém-nascido. Dados maternos e neonatais foram obtidos por questionários aplicados às mães e em prontuários médicos. A análise dos dados foi realizada por algoritmo da árvore de classificação, que dividiu o conjunto de dados em subconjuntos mutuamente exclusivos que melhor descreveram a variável resposta. Resultados: 405 recém-nascidos participaram do estudo, com média de 31,3±2,7 semanas de idade gestacional e mediana de peso ao nascer 1.412g (IQ=1.164-1.605g). Realizar o primeiro CPP com até 137h de vida (≤5,7 dias) foi associado a menor taxa de sepse tardia (p=0,02) para recém-nascidos que fizeram CPP diário de 112,5 a 174,7 min/dia (1,9 a 2,9h/dia), com redução na taxa de sepse (39,3% para 27,5%). Além disso, a duração do CPP>174,7min/dia (>2,9h/dia) foi relevante (p<0,001) para os recém-nascidos >1.344g, com redução nesse desfecho (21,1% para 6%). Conclusões: o CPP mostrou-se importante para redução das taxas de sepse tardia em recém-nascidos pré-termo, especialmente quando realizado de forma oportuna (≤5,7 dias) e prolongada (>2,9h/dia).

["A tragedy after giving birth": stories of women who have lost newborn children]. / "Revés de um parto": relatos de mulheres que perderam o filho no período neonatal.

The aim of this study was to learn how mothers interpret and explain the death of a newborn child. The study used a qualitative approach. We conducted semi-structured interviews with 15 women in São Luís, Maranhão State, Brazil, whose newborn infants died between July 2012 and July 2014. Data were collected from April 1st to August 29th, 2014. The interviews included questions on labor, delivery, birth, and postpartum. Thematic content analysis was performed. The mothers' testimony evidenced weaknesses in the network of care. Many of the mothers linked the care they received to events leading to their infants' death. Core meanings identified by the analysis included slow and negligent care in the maternity hospital, revealing a context of obstetric violence against the women. There is an evident need to create strategies to promote humane care during labor and childbirth, strengthening comprehensive and integrated public policies to meet the demands for care for pregnant women and their infants.

O objetivo deste estudo foi compreender como as mães interpretam e explicam a morte de seus filhos no período neonatal. Trata-se de uma pesquisa de abordagem qualitativa. Foram utilizadas entrevistas semiestruturadas com 15 mulheres residentes no Município de São Luís, Maranhão, Brasil, cujos recém-nascidos morreram no período de julho de 2012 a julho de 2014. A coleta de dados foi realizada entre 1º de abril e 29 de agosto de 2014. As entrevistas incluíram perguntas acerca do trabalho de parto, parto, nascimento e puerpério. Foi realizada análise de conteúdo na modalidade temática. A partir da fala das entrevistadas, foram evidenciadas fragilidades na rede de assistência. Para muitas, o atendimento recebido esteve relacionado a eventos que levaram à morte dos filhos. Foram identificados como núcleos de sentido a demora no atendimento e a negligência na maternidade, que evidenciaram um contexto de violência obstétrica sofrida pelas mulheres. Fica evidente a importância de criação de estratégias para promover e assegurar o cuidado humanizado no atendimento ao parto e nascimento. Deve-se buscar o fortalecimento de políticas públicas integralizadas que contemplem as demandas de atenção à saúde da mulher e da criança.

El objetivo de este estudio fue comprender cómo interpretan y explican las madres la muerte de sus hijos durante el período neonatal. Se trata de una investigación con enfoque cualitativo. Se utilizaron entrevistas semiestructuradas con 15 mujeres residentes en el municipio de São Luis, Maranhão, Brasil, cuyos recién nacidos murieron durante el período de julio de 2012 a julio de 2014. La recogida de datos se realizó entre el 1 de abril y el 29 de agosto de 2014. Las entrevistas incluyeron preguntas sobre el trabajo de parto, parto, nacimiento y puerperio. Se realizó un análisis de contenido en la modalidad temática. A partir de las intervenciones de las entrevistadas, se evidenciaron fragilidades en la red de asistencia. Para muchas, la atención recibida estuvo relacionada con eventos que llevaron a la muerte de sus hijos. Se identificaron como núcleos de sentido la tardanza en la atención y la negligencia en la maternidad, que evidenciaron un contexto de violencia obstétrica sufrida por las mujeres. Es evidente la importancia de crear estrategias para promover y asegurar el cuidado humanizado en la atención al parto y nacimiento. Se debe buscar el fortalecimiento de políticas públicas integradas que contemplen las demandas de atención a la salud de la mujer y del niño.

Factors associated with skin-to-skin contact less than 180 min/day in newborns weighing up to 1,800 g: multicenter study / Fatores associados ao contato pele a pele inferior a 180 min/dia em recém-nascidos com peso até 1.800 g: estudo multicêntrico

Abstract This article aims to evaluate the factors associated with a skin-to-skin contact time <180 min/day in newborns weighing up to 1,800 g during neonatal hospitalization. Prospective observational cohort study conducted in neonatal units of reference for the Kangaroo Method in Brazil. Data from 405 dyads (mother/child) were analyzed from May 2018 to March 2020. Maternal and neonatal explanatory variables were collected from medical records and interviews. Skin-to-skin contact was recorded in forms posted at the bedside, filled out by parents and staff. The outcome variable was the mean time of skin-to-skin contact < 180 min/day. Hierarchical modeling was performed by Poisson regression with robust variance. The variables associated with the outcome were "without easy access to the hospital", "without previous knowledge of the kangaroo method" and "having had morbidities during pregnancy". Mothers without easy access to the hospital and who are unaware of the kangaroo method should be priority targets for health policies to develop strategies that promote greater exposure to skin-to-skin contact during the hospitalization period of their children.

Resumo O objetivo deste artigo é avaliar os fatores associados ao tempo de contato pele a pele < 180 min/dia em recém-nascidos com peso até 1.800 g durante a internação neonatal. Estudo observacional tipo coorte prospectivo conduzido em unidades neonatais de referência no Brasil. Foram analisados dados de 405 díades (mãe/filho), no período de maio de 2018 a março de 2020. As características da mãe e do recém-nascido foram coletadas em prontuários e entrevistas, a realização do contato pele-a-pele era registrada em fichas anexadas ao leito, preenchidas pela equipe e pelos pais. A variável desfecho foi o tempo médio diário de contato pele-a-pele inferior a 180 minutos. Foi realizada modelagem hierarquizada utilizando a regressão de Poisson com variância robusta para cálculo das razões de prevalência. As variáveis que permaneceram independentemente associadas foram: "não ter fácil acesso ao hospital" (morar longe ou ter dificuldade de transporte), "não possuir conhecimento prévio sobre o método canguru" e "ter apresentado morbidades durante a gestação". Mães sem fácil acesso ao hospital e que desconhecem o método canguru devem ser alvos prioritários das políticas de saúde para desenvolver estratégias que promovam maior exposição ao contato pele a pele durante o período de internação de seus filhos.

Prevalence and Risk Factors for Microcephaly at Birth in Brazil in 2010.

OBJECTIVES: To estimate the baseline prevalence and risk factors for microcephaly at birth before the Zika virus epidemic in 2 Brazilian cities. METHODS: We used population-based data from the Brazilian Ribeirão Preto (RP) and São Luís (SL) birth cohort studies of 2010 that included hospital deliveries by resident mothers. The final sample was 7376 live births in RP and 4220 in SL. Gestational age was based on the date of the mother's last normal menstrual period or obstetric ultrasonography, if available. Microcephaly at birth was classified according to the criteria of the International Fetal and Newborn Growth Consortium for the 21st Century and the Brazilian Ministry of Health. Risk factors for microcephaly, proportionate and disproportionate microcephaly, and severe microcephaly were estimated in a hierarchized logistic regression model. RESULTS: According to the International Fetal and Newborn Growth Consortium for the 21st Century definition, the prevalence of microcephaly (>2 SDs below the mean for gestational age and sex) was higher in SL (3.5%) than in RP (2.5%). The prevalence of severe microcephaly (>3 SDs below the mean) was higher in SL (0.7%) than in RP (0.5%). Low maternal schooling, living in consensual union or without a companion, maternal smoking during pregnancy, primiparity, vaginal delivery, and intrauterine growth restriction were consistently associated with microcephaly. The number of cases of microcephaly is grossly underestimated, with an underreporting rate of ∼90%. CONCLUSIONS: The prevalence of severe microcephaly was much higher than expected in both cities. Our findings suggest that microcephaly was endemic in both municipalities before the circulation of the Zika virus.

Prevalence and factors associated with surfactant use in Brazilian Neonatal Intensive Care Units: A multilevel analysis.

The treatment with exogenous surfactant reduces mortality and the risk of complications in preterm newborns with Respiratory Distress Syndrome. Higher usage levels have been associated with individual and institutional factors. The study aimed to identify these factors associated with use of this technology in 16 public Brazilian Neonatal Units using logistic multilevel analysis. In a sample of 630 newborns the use at some time was 82.6%. Only 24.7% made use of this technology up to two hours after birth. An intraclass correlation of 0.30 showed that 30% of the variance in the use of exogenous surfactant could be assigned to the contextual level. In the final model, a greater severity score (SNAPPE-II) was associated with increased surfactant use (OR = 2.64), whereas being small for gestational age (SGA) (OR = 0.59) was associated with lower use of this technology. At the contextual level the number of beds in the unit >15 (OR = 5.86), units with higher complexity (OR = 1.73) or units with implemented Kangaroo Mother Care (OR = 2.91), especially units in Rio de Janeiro state (OR = 16.17) were associated with greater surfactant use. Although individual clinical features explained most of the variation in the use of this technology, factors linked to the institution were also of utmost importance.

Sentimentos, reações e expectativas de mães de crianças nascidas com microcefalia pelo vírus zika / Feelings, reactions and expectations of mothers of children born with microcephaly by zika virus

Resumo Introdução: Em 2015, o Brasil foi afetado pela epidemia de microcefalia. As famílias atingidas vivenciaram uma doença desconhecida. Objetivo: Analisar sentimentos, reações e expectativas de mães de crianças nascidas com microcefalia pelo vírus Zika. Método: Abordagem qualitativa. Realizadas entrevistas estruturadas e semiestruturadas com 19 mães e uma bisavó. Análise de conteúdo na modalidade temática. Resultados: Os sentimentos descritos foram tristeza, medo, ansiedade e, algumas vezes, culpa. As reações relatadas foram choque, desespero, busca por informações, negação e, além disso, cada entrevistada vivenciou diferentes formas de aceitação. O luto do filho desejado foi um processo lento e doloroso. A maioria teve gestação não planejada, o que pareceu não ter influenciado nos sentimentos e reações provocados pelo diagnóstico dos filhos. As expectativas em relação ao futuro da criança envolveram medo da morte prematura e preocupações com o desenvolvimento motor, especialmente a incapacidade de andar e comer sozinho, levando à dependência. Conclusões: Diante do nascimento de um filho com microcefalia, as mães precisaram refazer seus planos à luz de uma nova realidade, que impactou na qualidade de vida. Os profissionais precisam estar preparados para lidar com tais questões, garantindo também atenção às mães.

Abstract Background: In 2015, Brazil was affected by the microcephaly epidemic, when affected families experienced an unknown disease. Objective: To analyze the feelings, reactions, and expectations of mothers of children born with microcephaly due to the Zika virus. Method: Qualitative approach. Structured and semi-structured interviews were conducted with 19 mothers and a great-grandmother. Content analysis in thematic modality. Results: The feelings described were sadness, fear, anxiety and, sometimes, guilt. The reactions reported were shock, despair, search for information, denial, and each interviewee experienced different forms of acceptance. Grieving the desired child was a slow and painful process. Most had unplanned pregnancies, which did not seem to have influenced the feelings and reactions caused by the children's diagnosis. Expectations regarding the child's future involved fear of premature death, concerns about motor development, especially the inability to walk and eat alone, leading to dependence. Conclusion: Given the birth of a child with microcephaly, mothers needed to redo their plans in the light of a new reality, which impacted on their quality of life. Professionals need to be prepared to deal with such issues while also ensuring attention to mothers.
