Association of maternal, fetal and labor variables with a low Apgar score in the fifth minute in term pregnancy: a case-control study.

PURPOSE: To search for maternal, labor-related and fetal variables associated with low Apgar in the fifth minute in term pregnancy. METHODS: A retrospective case-control study with term births was conducted in a public teaching hospital from 2013 to 2020. Cases were term births with Apgar score less than 7 in the fifth minute, and controls, the next one or two births following a case, with Apgar of 7 or more. Non-cephalic presentations, multiples and malformations were excluded. We accessed 100 cases and 190 controls. We considered significant values of p < 0.05. RESULTS: Were accessed 27 variables which could be risk factors, from which 12 were associated with the outcome. We found a protective effect of prelabor cesarean for the outcome, odds ratio (OR) 0.38, p = 0.013. Consequently, we conducted two sets of analyses: in the whole group and in the group of laboring women. The values of OR were in general greater in the group of laboring women, compared with the whole group. We conducted multivariate analysis within the group of women in labor. The variables which fitted best in the model were nulliparity, male sex of the fetus, less than six prenatal visits and abnormal cardiotocography; all remained significant. An association of rupture of membranes more than 360 min with the outcome, even after controlling fpr duration of labor, was found; adjusted OR 2.45, p = 0.023. CONCLUSION: Twelve variables were associated with the outcome. Prelabor cesarean had a protective effect. The time of ruptured membranes was associated with low Apgar.

Prenatal Exposure to Mercury, Manganese, and Lead and Adverse Birth Outcomes in Suriname: A Population-Based Birth Cohort Study.

Globally, adverse birth outcomes are increasingly linked to prenatal exposure to environmental contaminants, such as mercury, manganese, and lead. This study aims to assess an association between prenatal exposure to mercury, manganese, and lead and the occurrence of adverse birth outcomes in 380 pregnant women in Suriname. The numbers of stillbirths, preterm births, low birth weights, and low Apgar scores were determined, as well as blood levels of mercury, manganese, lead, and relevant covariates. Descriptive statistics were calculated using frequency distributions. The associations between mercury, manganese, and lead blood levels, on the one hand, and adverse birth outcomes, on the other hand, were explored using contingency tables, tested with the χ2-test (Fisher's exact test), and expressed with a p value. Multivariate logistic regression models were computed to explore independent associations and expressed as (adjusted) odds ratios (aOR) with 95% confidence intervals (CI). The findings of this study indicate no statistically significant relationship between blood mercury, manganese, or lead levels and stillbirth, preterm birth, low birth weight, and low Apgar score. However, the covariate diabetes mellitus (aOR 5.58, 95% CI (1.38-22.53)) was independently associated with preterm birth and the covariate hypertension (aOR 2.72, 95% CI (1.081-6.86)) with low birth weight. Nevertheless, the observed high proportions of pregnant women with blood levels of mercury, manganese, and lead above the reference levels values of public health concern warrants environmental health research on risk factors for adverse birth outcomes to develop public health policy interventions to protect pregnant Surinamese women and their newborns from potential long-term effects.

RESUMEN Introducción: La depresión cardiorrespiratoria neonatal es un problema clínico que, en dependencia de su etiología, conduce a una alta morbilidad neurológica y elevada mortalidad. Objetivo: Caracterizar al recién nacido con depresión cardiorrespiratoria en el servicio de Neonatología del Hospital Ginecobstétrico "Fé del Valle Ramos", de Manzanillo, Granma. Método: Se realizó un estudio retrospectivo, observacional, descriptivo y transversal. Se seleccionaron 88 neonatos que cumplieron con los criterios de inclusión de recién nacido con depresión cardiorrespiratoria. Los datos se recolectaron durante el período de enero de 2017 a diciembre de 2018. Se tomaron en cuenta las siguientes variables: puntaje de Apgar, años de estudio, sexo, tipo de depresión cardiorrespiratoria, peso al nacer, factores maternos, edad gestacional y afecciones asociadas. Resultados: La depresión severa al nacer predominó en la mayoría de los neonatos (56,8 %). Prevalecieron los recién nacido de buen peso (73,9 %), nacidos a término (77,2 %). Las infecciones maternas (45,5 %) durante la gestación, el tiempo de rotura de membranas prolongado (31,8 %) y la presencia de líquido amniótico meconial (30,7 %), constituyeron los factores maternos que mayor vínculo guardaron con el neonato deprimido. Conclusiones: Las infecciones maternas, la rotura prematura de membranas, la presencia de líquido amniótico meconial, los nacimientos por cesárea, la nuliparidad, prematuridad y el embarazo en la adolescencia, son algunos de los factores de riesgo relacionados en este estudio que guardan vínculo estrecho con el predominio de estas afecciones en los neonatos deprimidos.

ABSTRACT Introduction: The cardiorespiratory depression in neonates is a clinical complication that, depending on its etiology, leads to high neurological morbidity and mortality. Objective: To characterize neonates with cardiorespiratory depression treated in the neonatology service at the Hospital Ginecobstétrico "Fé del Valle Ramos" in Manzanillo, Granma. Method: A retrospective, observational, descriptive and cross-sectional study was carried out. A total of 88 neonates with cardiorespiratory depression criteria were selected in the study. All information gathered includes the period January 2017 throughout December 2018. Variables assessed were as follow: Apgar score, years of study, sex, type of cardiorespiratory depression, birth weight, maternal factors, gestational age and associated conditions. Results: Severe depression at birth was predominant in most of neonates (56.8%). Newborn infants with a normal birth weight (73.9%), and born at term (77.2%) were predominant. Maternal infections during gestation (45.5%), prolonged rupture of membranes (31.8%) and the presence of meconium in the amniotic fluid (30.7%) were the maternal factors most associated with depressed neonate. Conclusions: The maternal infections, premature rupture of membranes, the presence of meconium in the amniotic fluid, cesarean birth, nulliparous status, premature and adolescent pregnancy are some of the risk factors assessed in this study that are closely linked to the prevalence of arising conditions in depressed neonates.

RESUMO Introdução: A depressão cardiorrespiratória neonatal é um problema clínico que, dependendo de sua etiologia, leva a alta morbidade neurológica e alta mortalidade. Objetivo: Caracterizar o recém-nascido com depressão cardiorrespiratória no serviço de Neonatologia do Hospital Gineco-obstétrico "Fé del Valle Ramos", Manzanillo, Granma. Método: Foi realizado um estudo retrospectivo, observacional, descritivo e transversal. Foram selecionados oitenta e oito lactentes que atenderam aos critérios de inclusão de um recém-nascido com depressão cardiorrespiratória. Os dados foram coletados no período de janeiro de 2017 a dezembro de 2018. Foram consideradas as seguintes variáveis: índice de Apgar, anos de estudo, sexo, tipo de depressão cardiorrespiratória, peso ao nascer, fatores maternos, idade gestacional e condições associadas. Resultados: A depressão grave ao nascer prevaleceu na maioria dos neonatos (56,8%). Prevaleceram os recém-nascidos de bom peso (73,9%) e a termo (77,2%). Infecções maternas (45,5%) durante a gestação, tempo prolongado de ruptura da membrana (31,8%) e presença de líquido amniótico mecônio (30,7%) foram os fatores maternos mais associados ao neonato deprimido. Conclusões: Infecções maternas, ruptura prematura de membranas, presença de líquido amniótico mecônio, partos cesáreos, nuliparidade, prematuridade e gravidez na adolescência, são alguns dos fatores de risco relacionados neste estudo que estão intimamente ligados ao predomínio dessas condições na recém-nascidos deprimidos.

Factores epidemiológicos y Apgar bajo al nacer / Epidemiological factors and low-Apgar at birth

INTRODUCCIÓN: El período más crucial de la vida humana corresponde a las primeras 24 h que siguen al nacimiento. En este período, la morbilidad y la mortalidad son elevadas, por lo que es necesario prevenir y conocer los factores de riesgo que puedan interferir en su normal desarrollo, evaluándose al nacer la puntuación de Apgar. OBJETIVOS: Identificar la posible asociación causal entre el índice de Apgar bajo y algunos factores epidemiológicos. Estimar a través del riesgo atribuible, aquellos factores que al actuar sobre ellos se lograría un mayor impacto en la población expuesta. MÉTODOS: Se realizó un estudio analítico observacional tipo caso control, relacionado con algunos factores epidemiológicos que inciden en la ocurrencia de Apgar bajo al nacer, en el Hospital Materno Provincial Docente Mariana Grajales Coello de Santiago de Cuba, desde el 1ro de enero de 2006 hasta el 31 de diciembre de 2007 . RESULTADOS: La edad materna y la edad gestacional al parto, el meconio en el líquido amniótico, las anomalías del cordón umbilical, el parto distócico y la restricción del crecimiento intrauterino están relacionados con el índice de Apgar bajo al nacer en esta institución. CONCLUSIONES: La depresión al nacer se asoció causalmente con las anomalías del cordón umbilical y el líquido amniótico meconial, teniendo asociación significativa la desnutrición fetal intrauterina, la edad gestacional al parto < 37 sem y ³ 42 sem y la presentación fetal distócica. Se comprobó que al actuar en el diagnóstico temprano y de certeza de un CIUR se lograría un mejor y mayor impacto en la población expuesta(AU)

INTRODUCTION: The more crucial moment in human life is that corresponding with the first 24 hr post-partum. During this period, morbidity and mortality are high, this it is necessary to prevent and to know risk factors that may to interfere in its normal development, assessing at birth the Apgar score. OBJECTIVES: To identify the possible causal association between the low Apgar score and some epidemiological factors. To estimate according to the attributing risk factors that acting on them it will be a great impact in exposed population. METHODS: An observational and analytical type case-control study was conducted related to some epidemiological factors having an impact on a low Apgar score at birth in the Mariana Grajales Mother Teaching Provincial Hospital of Santiago de Cuba from January 1, 2006 to December 31, 2007. RESULTS: Age mother and gestational age at labor, presence of meconium in amniotic fluid, umbilical cord abnormalities, dystocic labor and the intrauterine growth retard are related to a low Apgar score at birth in this institution. CONCLUSIONS: Depression at birth was associated in a causal way with umbilical cord abnormalities and the presence of meconium in amniotic fluid and a significant association with intrauterine fetal malnutrition, the gestational age at labor < 37 of weeks and ³ 42 weeks and dystocic fetal presentation. It was demonstrated that the retarded intrauterine growth (RIUG) acting in the early and certainty diagnosis it will be possible to achieve a better and major impact in exposed population(AU)
