Resumo O objetivo desse estudo foi conhecer os fatores associados à experiência materna no parto hospitalar. A metodologia utilizada foi uma revisão integrativa da literatura utilizando as bases de dados eletrônicas Medline (PubMed) e Biblioteca Virtual em Saúde BVS, tendo sido usados os seguintes comandos de busca: (("pregnant women" OR "postpartum period") AND perception AND ("childbirth experience" OR "labor obstetric"), selecionando artigos publicados a partir de 2017. A pesquisa finalizou com 15 referências bibliográficas onde foi possível identificar três grupos de resultados que influenciam a experiência materna, sendo eles apoio, informação/preparação para o parto e intervenções. Os estudos apontaram que os três grupos de resultados são elementos que se complementam. A percepção da experiência materna no parto é influenciada pelas condições socioeconômicas da mulher, pela preparação educacional para o parto, pelo apoio familiar e assistência da equipe de saúde durante o processo, pela qualidade e quantidade de intervenções realizadas e pelo respeito à autonomia da mulher nas decisões terapêuticas.

Abstract The objective of this study was to determine the factors associated with the maternal experience of hospital birth. An integrative literature review was performed using the electronic databases Medline (PubMed) and Biblioteca Virtual em Saúde (BVS - Virtual Health Library). The following search terms were used: (("pregnant women" OR "postpartum period") AND perception AND ("childbirth experience " OR "labor obstetric"), only articles published from 2017 onwards were selected. After selection, 15 bibliographical references were selected, where it was possible to identify three distinct groups of results, which were support, information/preparation for childbirth, and interventions. Our results suggest that the three result groups complement each other. We concluded that the maternal perception of the childbirth experience is influenced by socioeconomic conditions of the woman, educational preparation for the birth, family support, health team support during the labor process, quality and quantity of the interventions performed and respect to the woman’s autonomy in the therapeutical decisions.

RESUMO Objetivos. Avaliar a tendência da mortalidade neonatal, pós-neonatal e infantil de 1996 a 2020, na região metropolitana do estado do Rio de Janeiro e nas outras regiões. Métodos. Estudo ecológico utilizando regiões como unidade de análise. Os dados foram acessados no Sistema de Informações sobre Mortalidade e Sistema de Informações sobre Nascidos Vivos da Capital (Rio de Janeiro), dos territórios vizinhos (Niterói, São Gonçalo e Baixada Fluminense) e das outras regiões do Estado do Rio de Janeiro. Utilizamos a modelagem multinível de Poisson, onde as variáveis de resposta dos modelos foram mortalidade infantil e seus componentes neonatal e pós-neonatal. Os efeitos fixos dos modelos ajustados foram região e ano da morte. Resultados. No período 1996-2020, a Baixada Fluminense apresentou a maior taxa de mortalidade infantil de seus componentes neonatal e pós-natal na região metropolitana. Todos os modelos ajustados mostraram que quanto mais recente o ano, menor o risco de mortalidade. O risco ajustado da mortalidade infantil e seus componentes neonatal e pós-neonatal foi menor em Niterói. Conclusão. A Baixada Fluminense apresentou o maior risco de mortalidade infantil e de seus componentes neonatal e pós-neonatal na região metropolitana. Detectamos estabilização das taxas de mortalidade nos últimos anos.

ABSTRACT Objectives. The study aims to assess the trend of neonatal, post-neonatal, and infant mortality from 1996 to 2020 within the metropolitan region of the state of Rio de Janeiro and other regions. Methods. Ecological study using the region as analysis unity. Data were accessed from the Mortality Information System and Live Birth Information System in the capital Rio de Janeiro, in the neighboring areas of Niterói, São Gonçalo, Baixada Fluminense, and the remaining regions of the state of Rio de Janeiro State. We applied Poisson multilevel modeling, where the models’ response variables were infant mortality and its neonatal and post neonatal components. Fixed effects of the adjusted models were region and death year variables. Results. During the 1996-2020 period, the Baixada Fluminense showed the highest infant mortality rate as to its neonatal and post neonatal components. All adjusted models showed that the more recent the year the lower the mortality risk. Niterói showed the lowest adjusted risk of infant mortality and its neonatal and post neonatal components. Conclusion. Baixada Fluminense showed the highest mortality risk for infant mortality and its neonatal and post-neonatal components in the metropolitan region. The stabilization in mortality rates in recent years was identified by the research.

SUMMARY OBJECTIVE: This study aimed to describe the current situation of sexual aggression and assess the adhesion to ambulatory care follow-up. METHODS: This is a cross-sectional study involving female children and adolescents aged 0–19 years, treated at the Center for Multiprofessional Care of Sexual Violence of the General Hospital of Nova Iguaçu, from 2014 to 2018. RESULTS: Of the 453 children and adolescents, 264 (58.3%) were <14 years of age and 189 (41.7%) were 14–19 years of age. In both groups, 78% were black. School delay of >2 years was found in 15.6% of children in the age group <14 years and 40.5% of adolescents in the age group 14–19 years [p<0.001; OR=3.7 (2.1–65)]. In girls aged £13 years, abuse usually occurred at home (73.2%), which was perpetrated by one aggressor (91%) and known to the victim (91.2%). In adolescents aged ≥14 years, 84.1% of rapes occurred outside the home, practiced by one aggressor (74.8%), 57.8% were unknown, and in 91.2% of cases, there was use of physical force and/or verbal threats. The victims aged <14 years have 14 times more chance of experiencing aggression within the family setting [p<0.001; OR=14.3 (8.2–25.6)] and 16 times more chance of experiencing aggression from known persons [p<0.001; OR=16.2 (9.2–29.8)]. On the contrary, adolescents aged ≥14 years have three times more chance of being abused by more than one aggressor [p<0.001; OR=3.3 (1.8–6.1)]. CONCLUSION: Black girls, especially those aged <14 years, are in a situation of greater vulnerability for sexual violence, have less adhesion to follow-up, and often experience aggression in the household setting.

Abstract Although variation between observers in the assessment of the Apgar score, it remains a useful indicator of the general conditions of the newborn. This is a cross-sectional study based on population of live births in Brazil in 1999 and biennium 2018-2019. All declarations of live births (DNV) obtained from the Live Births System database were accessed. Frequencies were compared between groups using Pearson’s chi-square test and multivariate logistic regression analysis was performed. A statistical significance level of 0.05 was considered. We included 9.050.521 DNVs in our research. We found that 2,1% of newborns had 5th minute Apgar < 7 in 1999 compared with 0,9% in 2018-2019. Multivariate analysis shows that twins and teenage pregnancy are no longer risk factors. Among risk factors, we observed an increase in prematurity, low birth weight and congenital anomalies. An improvement in maternal markers was observed, especially increase in the number of prenatal consultations and schooling. Such findings demonstrate the importance access and adequate prenatal care and improved socioeconomic conditions as effective strategy to reduce neonatal morbidity and mortality.

Resumo Apesar da variação entre observadores na avaliação do escore de Apgar, ele permanece um indicador útil das condições gerais do recém-nascido. O presente trabalho é um estudo de corte transversal baseado na população de nascidos vivos no Brasil no ano de 1999 e no biênio 2018-2019. Foram avaliadas todas as declarações de nascidos vivos (DNV) obtidas a partir do banco de dados do Sistema de Informações sobre Nascidos Vivos. As frequências foram comparadas entre os grupos por meio do teste qui-quadrado de Pearson e foi realizada análise de regressão logística multivariada. Adotou-se nível de significância estatística de 0,05. Foram analisadas 9.050.521 DNVs em nossa pesquisa. Constatamos que 2,1% dos recém-nascidos tiveram Apgar de 5º minuto < 7 em 1999, em comparação com 0,9% em 2018-2019. A análise multivariada indicou que gemelidade e gravidez na adolescência deixaram de ser fatores de risco para Apgar de 5º minuto < 7. Entre os fatores de risco, nota-se aumento da prematuridade, baixo peso ao nascer e anomalias congênitas. Observou-se melhoria de marcadores maternos, em especial o aumento do número de consultas pré-natais e escolaridade. Tais achados mostram a importância de acesso e seguimento pré-natal adequado e investimento em melhores condições socioeconômicas como estratégia eficaz para redução de morbimortalidade neonatal.

SUMMARY OBJECTIVE: The aim of this study was to assess the rate of repeated pregnancy in adolescence and its association with early marriage and education level. METHODS: This is a cross-sectional study conducted by searching the Live Births Data System. The study included all adolescents in the age group 10–19 years with live births from 2015 to 2019 (n=2,405,248), divided into three groups: G1: primiparas; G2: with 1 previous pregnancy; and G3: with two or more previous pregnancies. RESULTS: Total repeated pregnancies remained stable, along the years. In the age group 10–14 years, the decrease in the period was from 5.0 to 4.7%, whereas in the age group 15–19 years, it was from 27.8 to 27.3%. Being married or in a stable union increases by 96% the chance of repeated pregnancy in the age group 10–14 years (p<0.001; OR=1.96; 95% confidence interval [CI] 1.85–2.09). In the age group 15–19 years, the chance of repeated pregnancy among the married or in stable union increased 40% (p<0.001; OR=1.40; 95%CI 1.39–1.41)). Girls aged 10–14 years with an education level of<8 years had a 64% higher chance of repeated pregnancy (p<0.001; OR=1.64; 95%CI 1.53–1.75), and among those aged 15–19 years, there was a 137% higher chance of repeated pregnancy (p<0.001; OR=2.37; 95%CI 2.35–2.38). CONCLUSION: Repeated pregnancy in adolescence in Brazil remains very high over the years. There is an association between low education level and early marriage with repeated pregnancies in adolescence.

Abstract Objectives: to evaluate the repercussions of motherhood on patients deprived of their liberty. Methods: integrative review based on research in electronic databases: Medline (PubMed), LILACS, SciELO and Nursing Database (BDENF), using the following search strategy: (“Prisons” [Majr] AND “Pregnancy” [ Mesh]), as of 2016. Results: the research ended with 33 bibliographic references, being the highest level of evidence from cohort studies, which demonstrate the precariousness of health care offered to these pregnant women. Three main groups of results were identified: low quality prenatal care, negative maternal and neonatal health indicators in relation to the general population and the emotional issues involved in prison reality during the period of pregnancy and puerperium. Conclusions: prenatal care has flaws that influence, in some way, the maternal and neonatal health indicators. In addition, the precarious structure of prison system directly interferes with the emotional health of these women.

Resumo Objetivos: avaliar as repercussões da maternidade em pacientes privadas da liberdade. Métodos: revisão integrativa a partir de pesquisa nas bases de dados eletrônicas: Medline (PubMed), LILACS, SciELO e Base de Dados de Enfermagem (BDENF), sendo usada como estratégia de busca: (“Prisons”[Majr] AND “Pregnancy”[Mesh]), a partir de 2016. Resultados: a pesquisa finalizou com 33 referências bibliográficas, sendo o maior nível de evidência de estudos de coorte, que demonstram a precarização na assistência de saúde ofertada a essas gestantes. Foram identificados três grupos principais de resultados: pré-natal de baixa qualidade, indicadores de saúde maternos e neonatais negativos e as questões emocionais envolvidas na realidade carcerária durante o período de gestação e puerpério. Conclusões: a assistência pré-natal apresenta falhas que influenciam nos indicadores de saúde maternos e neonatais. Além disso, a estrutura precária do sistema prisional interfere diretamente na saúde emocional dessas mulheres

ABSTRACT The aim of this study was to estimate the rate of Mother-to-child Transmission (MTCT) of HIV to neonates in a reference university hospital in Sao Luis city, the capital of Maranhao State (MA), evaluating MTCT-associated factors. A retrospective cohort study based on data from the Notifiable Diseases Data System (SINAN) was carried out and included all HIV-exposed neonates notified from 2013 to 2017 by the university hospital. The study population comprised 725 HIV-exposed neonates, of whom 672 neonates were exposed and uninfected, and 53 were exposed and infected. The estimated rate of MTCT in the period of 2013 to 2017 was 7.3%. Most pregnant women were ≥ 20 years old (86.9%), reported ≥ 8 years of schooling (53.2%), reported full-time or independent paid work (46.9%) and were residents in other cities of the state (61.7%). Regarding healthcare, 86.3% received prenatal care, 74.6% received Antiretroviral Therapy (ART) as prophylaxis during pregnancy, 81.8% received ART prophylaxis during childbirth and 78.1% underwent cesarean section. Among the neonates, 92.8% received ART prophylaxis and 94.3% were not breastfed. Despite these variables, the 7.3% MTCT rate found in this study makes it clear that the interventions recommended by the Ministry of Health were not fully adopted.

SUMMARY OBJECTIVE: The aim of this study was to analyze the occurrence and risk factors associated with infections during pregnancy in patients with systemic lupus erythematosus. METHODS: This is a retrospective cohort study using the data of pregnant women who were followed up between 2011 and 2018 at a university hospital. RESULTS: The data of 221 pregnant women with systemic lupus erythematosus were analyzed. The incidence of infections was 22.6% (50/221), with the urinary tract being the most frequent site of infection (32/221, 14.5%) followed by the respiratory tract (15/221, 6.8%). The bivariate analysis showed that active disease, hematological systemic lupus erythematosus, reduced complement, and use of prednisone ≥5 and ≥10 mg increased the chance of infection during early pregnancy (p=0.05, p=0.04, p=0.003, p=0.008, and p=0.02, respectively), while disease activity and anti-DNA positivity increased it at the end of pregnancy (p=0.03 and p=0.04, respectively). Prednisone at a dose ≥5 mg increased the chance of infection in the beginning (p=0.01) and at the end of pregnancy (p=0.008). Multivariate analysis showed that increasing the dose of prednisone from 5 to 10 mg tripled the chance of developing infections in pregnant women with lupus (p=0.02). CONCLUSION: The study showed an increased chance of infections in pregnant women with systemic lupus erythematosus and it was associated with the use of prednisone.

Resumo Este estudo teve como objetivo analisar o papel de fatores temporais, geográficos e sociodemográficos na mortalidade por câncer de próstata, mama, colo do útero, cólon, pulmão e esôfago nas capitais brasileiras (2000-2015). Estudo ecológico utilizando informações brasileiras de mortalidade. Modelos de Poisson multinível foram usados para estimar o risco ajustado de mortalidade por câncer. Os níveis de mortalidade foram maiores em homens para câncer de cólon, pulmão e esôfago. As taxas de mortalidade foram mais altas nos idosos. Nossos resultados mostraram risco aumentado de mortalidade por câncer de cólon em ambos os sexos de 2000 a 2015, o que também foi evidenciado para câncer de mama e de pulmão em mulheres. Em ambos os sexos, o maior risco de mortalidade para câncer de pulmão e esôfago foi observado nas capitais do Sul. As capitais do Centro-Oeste, Sul e Sudeste apresentaram o maior risco de mortalidade por câncer de cólon tanto para homens quanto para mulheres. A taxa de mortalidade por câncer de cólon aumentou para ambos os sexos, enquanto a mortalidade por câncer de mama e de pulmão aumentou apenas para as mulheres. A região Norte apresentou a menor taxa de mortalidade por câncer de mama, colo do útero, cólon e esôfago. As regiões Centro-Oeste e Nordeste apresentaram as maiores taxas de mortalidade por câncer de próstata.

Abstract This study aimed to analyze the role of period, geographic and socio demographic factors in cancer-related mortality by prostate, breast, cervix, colon, lung and esophagus cancer in Brazilians capitals (2000-2015). Ecological study using data of Brazilian Mortality Information. Multilevel Poisson models were used to estimate the adjusted risk of cancer mortality. Mortality rate levels were higher in males for colon, lung and esophageal cancers. Mortality rates were highest in the older. Our results showed an increased risk of colon cancer mortality in both sexes from 2000 to 2015, which was also evidenced for breast and lung cancers in women. In both genders, the highest mortality risk for lung and esophageal cancers was observed in Southern capitals. Midwestern, Southern and Southeastern capitals showed the highest mortality risk for colon cancer both for males and females. Colon cancer mortality rate increased for both genders, while breast and lung cancers mortality increased only for women. The North region showed the lowest mortality rate for breast, cervical, colon and esophageal cancers. The Midwest and Northeast regions showed the highest mortality rates for prostate cancer.

SUMMARY OBJECTIVE: This study aimed to assess live birth frequency and age-specific fertility rates (ASFR) in the period 1996–2018 and the number of pregnancies at <14 years old in the period 2012–2018. METHODS: This was a cross-sectional study conducted by search on Live Births Data System (SINASC/DATASUS) database. RESULTS: There was a variation in ASFR in Brazil of 0.78‰ in 1996 to 0.87‰ in 2018 (+11.5%). In the north region, it increased from 1.28‰ to 1.66‰ in 2018. In the northeast region, it increased from 0.72‰ to 1.66‰ (+131%) in 1996–2011, but decreased to 1.31‰ in 2018 (-21% in relation to 2011). When comparing 1996 and 2018, in the southeast region, there was a 22% decrease; in the south region, it was 48.2%; and in the Center-West region, it was 34%; but in the north region, there was a 29.7% increase, and in the northeast region, it was 81.9%. When adding girls who became pregnant aged 13 years and gave birth at 14, there was a threefold increase in the rate. CONCLUSIONS: The increase of pregnancies in <14 years old in less developed regions of Brazil shows an association with socioeconomic factors and reveals the severe problem of rape of vulnerable persons in the country.

SUMMARY OBJECTIVE: This study aimed to evaluate the frequency of late pregnancies in Brazil, the age-specific fertility rate (ASFR) in the regions, the rate of prematurity, and the rate of low birth weight (LBW) and their association with advanced maternal age compared with 20–34-year-old women. METHODS: This was a cross-sectional study conducted by searching the Information System on Live Births (Sistema de Informações Sobre Nascidos Vivos [SINASC]). Data from 1995 to 2018 were collected, and pregnant women were divided into three categories based on their age range: 35–39, 40–44, and ≥45 years. The study calculated the frequency of deliveries of mothers of advanced age in Brazil, the ASFR, and the rates of prematurity and LBW in each group. RESULTS: The frequency of newborns (NB) of mothers aged ≥35 years increased by 64%. The 35–39-year-old ASFR increased in all regions, except in the northeast. At maternal age ≥35 years, NB increased by 58% between 28 and 36 weeks during the study period. LBW increased between 500 and 1,499 g in 68.7% and between 1,500 and 2499 g in 57% of cases. In 2018, regarding the age range of 20–34 years, the chance of premature delivery was 29% at 35–39 years (OR=1.29), 54% higher at 40–44 years (OR=1.54), and 114% higher at ≥45 years (OR=2.14); while the chance of LBW increased by 28% at 35–39 years (OR=1.28), 56% at 40–44 years (OR=1.56), and 139% at 45 years or older (OR=2.39). CONCLUSIONS: The frequency of deliveries and ASFR ≥35 years increased between 1995 and 2018. The chances of prematurity and LBW were higher with increased maternal age.
