Abstract Introduction: Preterm birth, before 37 weeks of gestation, is the main determinant of neonatal morbidity and mortality and is associated with serious consequences,including compromised quality of life for the affected individual and physical, psychological, and economic costs. Objective: To evaluate the correlation of obstetric history, cervicovaginal infections, and cervical length with preterm birth. A prospective, blind cohort study evaluated 1,370 pregnant women from Ribeirão Preto between 20 and 25 weeks of gestation. Materials and methods: The correlation between obstetric history, cervical length, and gestational age at birth was obtained by calculating the relative risk of the different variables. Results: The distribution of pregnant women according to cervical length (CL) showed a predominance of women with a cervix longer than 2.5 cm (n = 1,308, 95.8%), followed by women with a cervix between 2 and 2.49 cm (n = 42, 3.1%) and < 2 cm (n = 15, 1.1%). Among the 1,370 pregnant women evaluated, 133 had spontaneous preterm birth (< 259 days); 14 (10.5%) preterm births occurred in women under 19 years of age, 105 (79%) in women between 19 and 35 years, and 14 (10.5%) in women older than 35 years. Microbiological analysis showed the growth of Mycoplasma hominis, Ureaplasma urealyticum, and other bacteria in 8, 17, and 16 women with preterm birth, respectively. Among the 133 women with spontaneous preterm birth, CL was < 2.5 cm in 15 women, < 2 cm in 3, < 1.5 cm in 3, and < 1 cm in 2. Conclusion: The identification of pregnant women at high risk for preterm delivery can reduce the incidence of preterm birth. Although no gold standard test exists for the prediction of preterm birth, this study confirms that the measurement of CL is a good individual predictor.

Problem: Preterm birth is the leading cause of death and can result in significant long-term loss of physical and psychological capacity among survivors.Background: An estimated 15 million babies are born preterm every year. Prediction models based on machine learning methods have reported promising results.Aims: To identify risk factors associated with preterm birth and to develop and validate a prediction model for this outcome in a Brazilian birth cohort.Methods: Cross-sectional study of all births that occurred in Ribeirão Preto-SP and of one in three births that occurred in São Luís-MA, Brazil, in 2010. Questionnaires were applied to obtain pregnancy-related data. Multivariate adaptive regression splines were used to determine the independent variables. Preterm birth, defined as birth before 37 weeks gestational age, was the dependent variable. A random forest model was developed and its performance was evaluated by ROC analysis.Findings: The preterm birth rates were 12.7% (RP) and 14.1% (SL). The prediction and validation accuracies of the RF-based model were 91.3% and 85.5% respectively. The model can be applied starting in the third month of gestation and is more effective in identifying preterm infants with GA&lt;31 weeks and 6 days (AUC=0.98).Discussion: It was possible to build a prediction model based on easily accessible low-cost data, without the need for complementary tests, providing results similar to those of other studies.Conclusions: Previous preterm birth and prenatal care were determinants. The use of an application for individualized patient monitoring an early stage can have positive effects on the quality of life of mother and child.

Abstract Objective: To identify sociodemographic and reproductive risk factors associated with MetS in women in their fourth decade of life. Methods: Cohort study conducted on women born from June 1978 to May 1979 in Ribeirão Preto, Brazil. Sociodemographic, clinical, and obstetric data were collected by interview and clinical evaluation. Univariable and multivariable binomial logistic regression models were constructed to identify the risk factors of metabolic syndrome and the adjusted relative risk (RR) was calculated. Results: The cohort included 916 women, and 286 (31.2%) of them have metabolic syndrome. MetS was associated with lack of paid work (RR 1.49; 95% CI 1.14-1.95), marital status of without a partner (RR 1.33; 95% CI 1.03-1.72), low educational level (less than 8 years of schooling [RR 1.72; 95% CI 1.23-2.41], 8 to 12 years of schooling [RR 1.37; 95% CI 1.06-1.76], when compared with more than 12 years of schooling), and teenage pregnancy (RR 2.00; 95% CI 1.45-2.77). There was no association between MetS, and the other covariates studied. Conclusion: Metabolic syndrome in a population of women in the fourth decade of life was associated with lack of employment, lack of a partner, low educational level, and teenage pregnancy.

Abstract In low and middle-income countries such as Brazil, most maternal deaths are related to hypertensive complications. Preeclampsia is the leading cause of maternal mortality and morbidity. Significant proportion is associated with the following factors: lack of identification of high-risk women, lack of adequate prevention, difficulty in maintaining a high-risk prenatal follow-up, delayed diagnosis, insecurity and low use of magnesium sulphate, delayed pregnancy interruption and lack of postpartum follow-up of these high-risk cases. Four major actions are proposed to minimize this alarming clinical picture and reduce the mortality rates due to preeclampsia, called the "4 P Rule" (Adequate Prevention – Vigilant Prenatal Care – Timely Delivery (Parturition) – Safe Postpartum). From this simple "rule" we can open a range of important processes and reminders that may help in the guidance of preeclampsia management. middleincome middle income Brazil complications morbidity factors highrisk high risk women prevention followup, followup follow up, up diagnosis sulphate cases 4 " Rule Adequate Parturition (Parturition Postpartum.

Abstract Objective To assess a panel of cytokines and placental insufficiency with the risk of preterm delivery (PTD). Methods Nested case-control study into the BRISA birth cohort. Eighty-two mother-infant-placenta pairs were selected at 20+0 to 25+6 weeks. Circulating biomarker levels were performed using Luminex flowmetric xMAP technology. Cytokines classified as Th1, Th2 or Th17 and other biomarkers were selected. The ratio between birth weight and placental weight (BW/PW) was used as a proxy for placental efficiency. Spearman correlation, univariate analyses and logistic regression models were calculated. Sensitivity, specificity, positive and negative likelihood ratios were calculated using the Receiver Operating Characteristic curve. Results Mean gestational age was 250 days, 14,6% were small for gestational age, 4,8% large for gestational age and 13,4% stunted. Placental efficiency was higher for term newborns (p<0,001), and 18/22 (81%) preterm biomarker values were higher than the control group. Th1 cytokines were highly correlated, while the weakest correlation was observed in other biomarkers. Less education was associated with a higher risk of PTD (p = 0.046), while there was no appreciable difference in the risk of PTD for placental insufficiency. Biomarkers showed negligible adjusted OR of PTD (0.90 to 1.02). IL-6, IL-8, IL-1β, TNFβ, IL-4, IL-13, GCSF, MIP1A, VEGF, EGF, and FGF2 presented a higher sensitivity ranging from 75.56% to 91.11%. Conclusion IL-8, IL-12p40, IL-4, IL-13, GCSF, MIP1B, and GMSF in asymptomatic pregnant women were associated with PTD. This finding suggests an activation of maternal inflammatory response. .

Resumo Objetivos Avaliar o desempenho das curvas de Intergrowth-21 st (INT) e Fetal Medicine Foundation (FMF) na predição de resultados perinatais e de neurodesenvolvimento de recém-nascidos com peso abaixo do percentil 3. Métodos Foram incluídas gestantes de feto único com idade inferior a 20 semanas de uma população geral em unidades de saúde não hospitalares. Seus filhos foram avaliados ao nascimento e no segundo ou terceiro anos de vida. Os recém-nascidos tiveram seus percentis de peso calculados para ambas as curvas. Sensibilidade, especificidade, valor preditivo positivo (VPP) e negativo (VPN) e área sob a curva ROC (ROC-AUC) foram calculados para desfechos perinatais e atraso de neurodesenvolvimento considerando o peso ao nascimento menor que o percentil 3 como ponto de corte. Resultados Um total de 967 crianças foram avaliadas ao nascimento e no segundo ou terceiro anos de vida. A idade gestacional ao nascer foi de 39,3 (±3,6) semanas e o peso ao nascimento foi de 3.215,0 (±588,0) g. INT e FMF classificaram 19 (2,4%) e49 (5,7%) recém-nascidos abaixo do percentil 3, respectivamente. A prevalência de parto prétermo, intubação traqueal > 24 horas nos primeiros três meses de vida, Apgar de 5° minuto < 7, internação em unidade de terapia intensiva neonatal (internação em UTIN), taxa de cesariana e atraso de neurodesenvolvimento foi 9,3%, 3,3%, 1,3%, 5,9%, 38,9% e 7,3% respectivamente. Em geral, o percentil 3 de ambas as curvas apresentou baixa sensibilidade e VPP e alta especificidade e VPN. O percentil 3 de FMF mostrou sensibilidade superior para parto prematuro, internação em UTIN e taxa de cesariana. INT foi mais específico para todos os desfechos e apresentou maior VPP para o atraso do neurodesenvolvimento. Entretanto, exceto por uma pequena diferença na predição de parto pré-termo em favor de INT, as curvas ROC não mostraram diferenças na predição de resultados perinatais e de desenvolvimento neurológico. Conclusão O peso ao nascer abaixo do percentil 3 segundo INT ou FMF isoladamente foi insuficiente para um bom desempenho diagnóstico de desfechos perinatais e de neurodesenvolvimento. As análises realizadas não puderam mostrar que uma curva é melhor que a outra em nossa população. INT pode ter vantagem em cenários de contingência de recursos, pois discrimina menos recém-nascidos abaixo do percentil 3 sem aumentar os desfechos adversos.

Abstract Objectives To evaluate the performance of Intergrowth-21 st (INT) and Fetal Medicine Foundation (FMF) curves in predicting perinatal and neurodevelopmental outcomes in newborns weighing below the 3rd percentile. Methods Pregnant women with a single fetus aged less than 20 weeks from a general population in non-hospital health units were included. Their children were evaluated at birth and in the second or third years of life. Newborns (NB) had their weight percentiles calculated for both curves. Sensitivity, specificity, positive (PPV) and negative predictive value (NPV), and area under the ROC curve (ROC-AUC) for perinatal outcomes and neurodevelopmental delay were calculated using birth weight < 3rd percentile as the cutoff. Results A total of 967 children were evaluated. Gestational age at birth was 39.3 (± 3.6) weeks and birth weight was 3,215.0 (± 588.0) g. INT and FMF classified 19 (2.4%) and 49 (5.7%) newborns below the 3rd percentile, respectively. The prevalence of preterm birth, tracheal intubation >24 hours in the first three months of life, 5th minute Apgar <7, admission to a neonatal care unit (NICU admission), cesarean section rate, and the neurodevelopmental delay was 9.3%, 3.3%, 1.3%, 5.9%, 38.9%, and 7.3% respectively. In general, the 3rd percentile of both curves showed low sensitivity and PPV and high specificity and NPV. The 3rd percentile of FMF showed superior sensitivity for preterm birth, NICU admission, and cesarean section rate. INT was more specific for all outcomes and presented a higher PPV for the neurodevelopmental delay. However, except for a slight difference in the prediction of preterm birth in favor of INT, the ROC curves showed no differences in the prediction of perinatal and neurodevelopmental outcomes. Conclusion Birth weight below the 3rd percentile according to INT or FMF alone was insufficient for a good diagnostic performance of perinatal and neurodevelopmental outcomes. The analyzes performed could not show that one curve is better than the other in our population. INT may have an advantage in resource contingency scenarios as it discriminates fewer NB below the 3rd percentile without increasing adverse outcomes.

RESUMO Objetivo: Descrever as alterações nas características sociodemográficas, econômicas e variáveis relacionadas à caracterização da família, saúde e educação durante a pandemia da COVID-19, em uma coorte de nascimento avaliada aos 10–11 anos de idade. Métodos: Estudo transversal envolvendo 1.033 crianças de uma coorte de nascidos em 2010/2011, na cidade de Ribeirão Preto, SP, Brasil. Os dados foram obtidos por meio de entrevistas por telefone ou videochamada com o responsável pela criança, no período de julho a outubro de 2021. Os questionários abordaram informações sobre a organização familiar, comportamento e saúde da criança, acompanhamento escolar, avaliação socioeconômica e ocorrência da COVID-19 durante o período de isolamento social. Foi realizada estatística descritiva. O teste qui-quadrado foi utilizado para verificar diferenças de grupos por salários-mínimos (SM). Resultados: Dos entrevistados, 47,6% relataram piora na condição financeira durante a pandemia, sendo a piora econômica mais frequente no grupo de renda familiar <3 SM em comparação ao grupo de >6 SM (59,1 vs. 15,7%; p<0,001). Segundo os responsáveis, 62% das crianças apresentaram mudança de comportamento durante o período, sendo a ansiedade relatada com mais frequência. Ainda, 61,4% das crianças apresentaram dificuldades de aprendizagem, e o prejuízo foi mais acentuado naquelas de menor renda familiar em comparação às de maior renda (74,7 vs. 45,1%; p<0,001). Conclusão: A pandemia da COVID-19 alterou diferentes aspectos econômicos das famílias, assim como indicadores educacionais, de saúde e de comportamento das crianças. As famílias de menor renda foram as mais prejudicadas tanto do ponto de vista econômico como nos demais indicadores.

ABSTRACT Objective: To describe changes in sociodemographic, economic and variables related to the characterization of family, health and education during the COVID-19 pandemic in a birth cohort evaluated at 10–11 years of age. Methods: Cross-sectional study involving 1,033 children from a cohort of children born in 2010/2011, in the city of Ribeirão Preto, SP, Brazil. Data were collected from July to October 2021 by telephone or video interview held with the person responsible for the child. The questionnaires discussed family organization, child behavior and health, school attendance, socioeconomic assessment and occurrence of COVID-19 during the period of social isolation due to the pandemic. Descriptive statistics were used to describe the data. The chi-square test was used to verify group differences by minimum wages (MW). Results: Of the respondents, 47.6% reported worsening of their financial situation during the pandemic, which was more frequent in the group with a household income <3 MW compared to the group with >6 MW (59.1 vs. 15.7%; p<0.001). According to the respondents, 62% of the children exhibited behavioral changes during the period and anxiety was the most frequently reported condition. In addition, 61.4% of the children had learning difficulties and these problems were more prevalent among children from households with lower incomes compared to those with higher incomes (74.7 vs. 45.1%; p<0.001). Conclusion: The COVID-19 pandemic has changed different economic aspects of families, as well as educational, health and behavioral indicators of children. Lower-income families were the most affected both economically and in terms of other indicators.

Resumo Objetivo: Avaliar a capacidade do Doppler fetal e características materno-obstétricas na predição de cesariana por comprometimento fetal intraparto (CFI), índice de Apgar de 5º min < 7 e desfecho perinatal adverso (DPA) em uma população de alto risco. Materiais e Métodos: Estudo de coorte prospectivo envolvendo 613 parturientes admitidas para indução ou em início de trabalho de parto espontâneo que realizaram ultrassonografia Doppler nas 72 horas anteriores ao parto. Os desfechos foram cesariana por CFI, índice de Apgar de 5º min < 7 e DPA. Resultados: As características maternas não foram associadas nem preditoras de DPA. Índice de resistência (IR) da artéria umbilical (AU) anormal (p = 0,03) e necessidade de medidas de ressuscitação intrauterina (p < 0,0001) permaneceram como fatores de risco significativos para cesariana por CFI. IR AU > 95º e razão cerebroplacentária (RCP) < 0,98 foram preditores de cesariana. Idade gestacional e IR AU > 0,84 foram os preditores de índice de Apgar de 5º min < 7 para recém-nascidos < 29 e ≥ 29 semanas, respectivamente. IR AU e RCP apresentaram acurácia moderada na predição de DPA (área sob a curva ROC de 0,76 e 0,72, respectivamente). Conclusão: IR UA mostrou-se preditor significativo de DPA.

Abstract Objective: To evaluate the capacity of fetal Doppler, maternal, and obstetric characteristics for the prediction of cesarean section due to intrapartum fetal compromise (IFC), a 5-min Apgar score < 7, and an adverse perinatal outcome (APO), in a high-risk population. Materials and Methods: This was a prospective cohort study involving 613 singleton pregnant women, admitted for labor induction or at the beginning of spontaneous labor, who underwent Doppler ultrasound within the last 72 h before delivery. The outcome measures were cesarean section due to IFC, a 5-min Apgar score < 7, and any APO. Results: We found that maternal characteristics were neither associated with nor predictors of an APO. Abnormal umbilical artery (UA) resistance index (RI) and the need for intrauterine resuscitation were found to be significant risk factors for cesarean section due to IFC (p = 0.03 and p < 0.0001, respectively). A UA RI > the 95th percentile and a cerebroplacental ratio (CPR) < 0.98 were also found to be predictors of cesarean section due to IFC. Gestational age and a UA RI > 0.84 were found to be predictors of a 5-min Apgar score < 7 for newborns at < 29 and ≥ 29 weeks, respectively. The UA RI and CPR presented moderate accuracy in predicting an APO, with areas under the ROC curve of 0.76 and 0.72, respectively. Conclusion: A high UA RI appears to be a significant predictor of an APO. The CPR seems to be predictive of cesarean section due to IFC and of an APO in late preterm and term newborns.

Os questionários abordaram informações sobre a organização familiar, comportamento e saúde da criança, acompanhamento escolar, avaliação socioeconômica e ocorrência da COVID-19 durante o período de isolamento social. Foi realizada estatística descritiva. O teste qui-quadrado foi utilizado para verificar diferenças de grupos por salários-mínimos (SM). Resultados: Dos entrevistados, 47,6% relataram piora na condição financeira durante a pandemia, sendo a piora econômica mais frequente no grupo de renda familiar <3 SM em comparação ao grupo de >6 SM (59,1 vs. 15,7%; p<0,001). Segundo os responsáveis, 62% das crianças apresentaram mudança de comportamento durante o período, sendo a ansiedade relatada com mais frequência. Ainda, 61,4% das crianças apresentaram dificuldades de aprendizagem, e o prejuízo foi mais acentuado naquelas de menor renda familiar em comparação às de maior renda (74,7 vs. 45,1%; p<0,001). Conclusão: A pandemia da COVID-19 alterou diferentes aspectos econômicos das famílias, assim como indicadores educacionais, de saúde e de comportamento das crianças. As famílias de menor renda foram as mais prejudicadas tanto do ponto de vista econômico como nos demais indicadores.

ABSTRACT Objective: To describe changes in sociodemographic, economic and variables related to the characterization of family, health and education during the COVID-19 pandemic in a birth cohort evaluated at 10–11 years of age. Methods: Cross-sectional study involving 1,033 children from a cohort of children born in 2010/2011, in the city of Ribeirão Preto, SP, Brazil. Data were collected from July to October 2021 by telephone or video interview held with the person responsible for the child. The questionnaires discussed family organization, child behavior and health, school attendance, socioeconomic assessment and occurrence of COVID-19 during the period of social isolation due to the pandemic. Descriptive statistics were used to describe the data. The chi-square test was used to verify group differences by minimum wages (MW). Results: Of the respondents, 47.6% reported worsening of their financial situation during the pandemic, which was more frequent in the group with a household income <3 MW compared to the group with >6 MW (59.1 vs. 15.7%; p<0.001). According to the respondents, 62% of the children exhibited behavioral changes during the period and anxiety was the most frequently reported condition. In addition, 61.4% of the children had learning difficulties and these problems were more prevalent among children from households with lower incomes compared to those with higher incomes (74.7 vs. 45.1%; p<0.001). Conclusion: The COVID-19 pandemic has changed different economic aspects of families, as well as educational, health and behavioral indicators of children. Lower-income families were the most affected both economically and in terms of other indicators.

Resumo Objetivo um desafio considerar o diagnóstico e o tratamento da pré-eclâmpsia (PE) em locais de baixa e média renda, onde a doença representa um grande problema de saúde pública. A placenta é a causa subjacente da doença, e as concentrações plasmáticas de fatores pró-angiogênicos e antiangiogênicos liberados pela placenta podem refletir os riscos de progressão da doença. Proteínas antiangiogênicas, como a tirosina quinase fms solúvel tipo 1 (sFlt-1), e pró-angiogênicas, como o fator de crescimento placentário (PlGF), estão direta e inversamente correlacionados com o início da doença, respectivamente. Métodos Revisão narrativa sobre o uso de biomarcadores (razão sFlt-1/PlGF) com sugestão de protocolo de orientação para uso clínico. Resultados Principais considerações sobre o uso de biomarcadores: a razão sFlt-1/PlGF é principalmente relevante para descartar PE entre 20 e 36 6/7 semanas em casos de suspeita de PE; entretanto, não deve substituir os exames de rotina para o diagnóstico de PE. A relação sFlt-1/PlGF não deve ser realizada após a confirmação do diagnóstico de PE (apenas em ambientes de pesquisa). Em mulheres com suspeita de PE, a razão sFlt-1/PlGF < 38 pode descartar o diagnóstico de PE por 1 semana (VPN = 99,3) e até 4 semanas (VPN = 94,3); A relação sFlt-1/PlGF > 38 pode auxiliar no manejo clínico. Em casos de hipertensão grave e/ou sintomas (eclâmpsia iminente), a hospitalização é imprescindível, independentemente do resultado da relação sFlt-1/PlGF. Conclusão O uso de biomarcadores pode auxiliar na tomada de decisões clínicas no manejo de casos suspeitos de PE, principalmente para afastar o diagnóstico da doença, evitando intervenções desnecessárias, tais como internações e prematuridade iatrogênica.

Abstract Objective It is a challenge to consider preeclampsia (PE) diagnosis and management in low and middle-income settings, where it represents a major public health concern. The placenta is the underlying cause of disease, and the plasma concentrations of proangiogenic and antiangiogenic factors released by the placenta can reflect the risks of disease progression. Antiangiogenic proteins, such as soluble fms-like tyrosine kinase 1 (sFlt-1), and proangiogenic, like placental growth factors (PlGF), are directly and inversely correlated with the disease onset, respectively. Methods Narrative review on the use of biomarkers (sFlt-1 to PlGF ratio) with a suggested guidance protocol. Results Key considerations on the use of biomarkers: the sFlt-1/PlGF ratio is mainly relevant to rule out PE between 20 and 36 6/7 weeks in cases of suspected PE; however, it should not replace the routine exams for the diagnosis of PE. The sFlt-1/PlGF ratio should not be performed after confirmed PE diagnosis (only in research settings). In women with suspected PE, sFlt-1/PlGF ratio < 38 can rule out the diagnosis of PE for 1 week (VPN = 99.3) and up to 4 weeks (VPN= 94.3); sFlt-1/PlGF ratio > 38 does not confirm the diagnosis of PE; however, it can assist clinical management. In cases of severe hypertension and/or symptoms (imminent eclampsia), hospitalization is imperative, regardless of the result of the sFlt-1/PlGF ratio. Conclusion The use of biomarkers can help support clinical decisions on the management of suspected PE cases, especially to rule out PE diagnosis, thus avoiding unnecessary interventions, especially hospitalizations and elective prematurity

Resumo O objetivo do estudo foi estimar percepção e ocorrência de situações de abuso, desrespeito e maltrato (ADM) na assistência ao parto de 745 mulheres pertencentes às coortes de nascimentos de Ribeirão Preto. Foram aplicados questionários sigilosos contendo uma pergunta sobre percepção de maltrato na assistência ao parto e outras sobre exposição a situações de ADM. Utilizou-se o teste qui-quadrado para comparar as situações apresentadas entres as mulheres que relataram ou não maltrato. A análise foi realizada por meio do programa Stata 14. Das 745 mulheres avaliadas, 66,2% foram expostas a alguma situação de ADM e 8,3% referiram ter percebido ADM. As situações mais frequentes foram: 30,5% não puderam comer nem beber nada; 27,5% tiveram sua barriga apertada para ajudar a criança a nascer; e 25,5% não puderam ficar com acompanhante de sua escolha. Mulheres que afirmaram ter sofrido maltrato apresentaram maiores frequências de respostas positivas a todas situações de ADM quando comparadas com às demais, exceto para os seguintes relatos: “Não me deixaram comer nem beber nada” (p = 0,975) e “Fui forçada a ter parto cesáreo contra minha vontade” (p = 0,073). Apesar de a maior parte das mulheres pertencentes às coortes de Ribeirão Preto relatarem exposição a situações de ADM durante a assistência ao parto, uma minoria percebeu desrespeito ou maltrato.

Abstract This study aimed to estimate the perception and frequency of abuse, disrespect and mistreatment (ADM) situations during childbirth care of 745 women from the Ribeirão Preto birt cohorts. Confidential questionnaires containing one question regarding perceived abuse during childbirth care and other questions addressing exposure to ADM situations were applied. The chi-squared test was used to compare the situations presented between women who did and did not report mistreatment using the Stata 14.0 software. Among the 745 women evaluated, 66.2% were exposed to some situation of ADM and 8.3% reported having perceived ADM. The most frequent situations were that the woman could not eat or drink (30.5%), the woman had her belly squeezed to help the child be born (27.5%), and the woman could not stay with a companion of her choice (25.5%). Women who reported to have suffered maltreatment more frequently responded positively to all situations of ADM when compared to the other participants, except for the following statements: “I was not allowed to eat or drink anything” (p = 0.975) and “I was forced to have a cesarean delivery against my will” (p = 0.073). Although most women of the Ribeirão Preto cohorts reported exposure to ADM situations during childbirth care, a minority perceived disrespect or mistreatment.

Resumo O objetivo deste estudo foi investigar a associação entre fatores sociodemográficos, estilo de vida, perfil reprodutivo maternos e atenção pré-natal e ao parto com a morbidade near miss neonatal (NMN), em quatro coortes de nascimento. Este estudo envolveu quatro coortes de nascimento: Ribeirão Preto (RP) e São Luís (SL) (2010), Pelotas 2004 (PEL04) e 2015 (PEL15). Foi considerado NMN quando presente uma ou mais das seguintes condições: peso ao nascer <1.500g, índice de Apgar <7 no quinto minuto de vida, idade gestacional <32 semanas e relato de malformações congênitas. As covariáveis foram obtidas por meio de questionários aplicados às puérperas. Para análise, foi utilizada regressão logística múltipla com abordagem hierarquizada. Algumas particularidades entre as coortes foram verificadas. Nas coortes de RP e SL foram observadas associações dos fatores dos níveis mais distais (sociodemográficas, estilo de vida e perfil reprodutivo) com o NMN. Por outro lado, em PEL os fatores proximais relacionados à atenção à saúde foram mais significativos para ocorrência de NMN. Apenas a não realização do pré-natal associou-se ao NMN em todas as coortes: RP (OR=4,27, IC95% 2,16-8,45), SL (OR=2,32, IC95% 1,09-4,94), PEL04 (OR=4,79, IC95% 1,59-14,46) e PEL15 (OR=5,10, IC95% 2,60-9,97).

Abstract The aim of this study was to investigate the association of sociodemographic factors, lifestyle, maternal reproductive profile and prenatal and childbirth care with neonatal near miss (NNM) morbidity in four birth cohorts. This study involved four population-based birth cohorts: Ribeirão Preto (RP) and São Luís (SL) (2010), Pelotas 2004 (PEL04) and 2015 (PEL15). NNM was defined when one or more of the following conditions were present: birthweight <1,500 g, 5-minute Apgar score <7, gestational age <32 weeks, and report of congenital malformations. The covariates were obtained with questionnaires applied to the puerperal women. Some particularities between cohorts were identified. In the RP and SL cohorts, factors of the more distal levels (sociodemographic, lifestyle, and reproductive profile) were associated with NNM. On the other hand, proximal factors related to healthcare were more significant for the occurrence of NNM in PEL. Only the absence of prenatal care was associated with NNM in all cohorts: RP (OR=4.27, 95%CI 2.16-8.45), SL (OR=2.32, 95%CI 1.09-4.94), PEL04 (OR=4.79, 95%CI 1.59-14.46), and PEL15 (OR=5.10, 95%CI 2.60-9.97).

Resumo Objetivo A hipertensão gestacional (GH) é caracterizada pelo aumento da pressão sanguínea após a 20ª semana de gestação; a presença de proteinuria e/ou sinais de danos a órgãos como rins, fígado e cérebro indicam pré-eclâmpsia (PE). A heme oxigenase-1 (HO-1) é uma enzima antioxidante com um papel importante na manutenção da função endotelial, e a sua indução por certas moléculas se mostra potencialmente benéfica frente à característica deletéria destas condições sobre o endotélio. Já foi demonstrado anteriormente que a produção de HO-1 pode ser induzida por iodeto de potássio (KI). Portanto, nós avaliamos os efeitos do KI sobre a citotoxicidade e expressão de HO-1 por células de veia de cordão umbilical humano (HUVECs) após incubação com o plasma de mulheres diagnosticadas com GH ou PE. Métodos Células de veia de cordão umbilical humano foram incubadas com pool de plasma de gestantes saudáveis (n = 12), gestantes com GH (n = 10) ou gestantes com PE (n = 11) com ou sem a adição de KI por 24 horas para avaliar a citotoxicidade através da dosagem de lactato desidrogenase e produção de HO-1 por ELISA. Foi realizada ANOVA seguida de teste de Dunnet para múltiplas comparações entre os grupos estudados, considerando significativos valores de p ≤ 0,05. Resultados A solução de KI (1.000 µM) reduziu a produção de HO-1 no grupo GH (p = 0.0018) e a citotoxicidade no grupo PE (p = 0.0143); o tratamento com KI não afetou a produção de HO-1 por HUVECs incubadas com o plasma do grupo PE. Conclusão Nossos achados sugerem que o KI atenua os efeitos do plasma de gestantes com GH ocasionando a diminuição da produção de HO-1; plasma do grupo PE não induziu a produção de HO-1 em HUVECs em comparação ao grupo saudável, e nossa hipótese é a de que tal achado pode ser devido a mecanismos pós-transcricionais em resposta a uma superestimulação da produção de HO-1 nos estágios iniciais da gravidez.

Abstract Objective Gestational hypertension (GH) is characterized by increased blood pressure after the 20th gestational week; the presence of proteinuria and/or signs of end-organ damage indicate preeclampsia (PE). Heme oxygenase-1 (HO-1) is an antioxidant enzyme with an important role in maintaining endothelial function, and induction of HO-1 by certain molecules shows potential in attenuating the condition’s effects over endothelial tissue. HO-1 production can also be stimulated by potassium iodide (KI). Therefore, we evaluated the effects of KI over HO-1 expression in human umbilical vein endothelial cells (HUVECs) incubated with plasma from women diagnosed with GH or PE. Methods Human umbilical vein endothelial cells were incubated with a pool of plasma of healthy pregnant women (n = 12), pregnant women diagnosed with GH (n = 10) or preeclamptic women (n = 11)with or without the addition of KI for 24 hours to evaluate its effect on this enzyme expression. Analysis of variance was performed followed by Dunnet’s test for multiple comparisons between groups only or between groups with addition of KI (p ≤ 0.05). Results KI solution (1,000 µM) reduced HO-1 in the gestational hypertension group (p = 0.0018) and cytotoxicity in the preeclamptic group (p = 0.0143); treatment with KI reduced plasma cytotoxicity but did not affect the preeclamptic group’s HO-1 expression. Conclusion Our findings suggest that KI alleviates oxidative stress leading to decreased HO-1 expression; plasma from preeclamptic women did not induce the enzyme’s expression in HUVECs, and we hypothesize that this is possibly due to inhibitory post-transcriptional mechanisms in response to overexpression of this enzyme during early pregnancy.
