Resumo Estudos têm demonstrado consistentemente um aumento significativo no risco de defeitos cardíacos congênitos em filhos de mães diabéticas em comparação com os de gestações não diabéticas. Evidências apontam que todos os tipos de diabetes pré-gestacional têm capacidade de gerar malformações cardíacas mais acentuadas do que no diabetes gestacional e parece haver um risco aumentado para todos os fenótipos de cardiopatias congênitas na presença de diabetes materno. Atualmente, está em estudo a aplicação de algumas terapias na tentativa de diminuir os riscos inerentes à gravidez diabética; no entanto, ainda não foi possível comprovar totalmente a sua eficácia. A presente revisão visa compreender melhor os mecanismos que regem a associação entre diabetes pré-gestacional e cardiopatias congênitas e como o diabetes materno interfere no desenvolvimento cardíaco fetal, pois ainda há um longo caminho a percorrer na investigação deste processo complexo. prégestacional pré Atualmente diabética entanto eficácia fetal complexo

Abstract Studies have consistently shown a significant increase in the risk of congenital heart defects in the offspring of diabetic mothers compared with those of nondiabetic pregnancies. Evidence points that all types of pregestational diabetes have the capacity of generating cardiac malformations in a more accentuated manner than in gestational diabetes, and there seems to be an increased risk for all congenital heart defects phenotypes in the presence of maternal diabetes. Currently, the application of some therapies is under study in an attempt to reduce the risks inherent to diabetic pregnancies; however, it has not yet been possible to fully prove their effectiveness. The present review aims to better understand the mechanisms that govern the association between pregestational diabetes and congenital heart defects and how maternal diabetes interferes with fetal cardiac development, as there is still a long way to go in the investigation of this complex process. pregnancies Currently however effectiveness development process

Abstract Gut dysbiosis may contribute to the pathogenesis of gestational diabetes, encouraging the emergence of new prevention and treatment approaches based on the use of probiotics. This review aims to elucidate the changes in the gut microbiota associated with gestational diabetes, how they contribute to its pathophysiology, the mechanisms of action of probiotics, and their role in the prevention and treatment of the disease. The literature review showed that gestational diabetes is associated with an increase of gram-negative bacteria and a decrease of gram-positive bacteria producing short-chain fatty acids. This gut dysbiosis can provide changes in glucose homeostasis through mechanisms involving decreased secretion of incretins and increased inflammation. Although probiotic supplementation improves this dysregulation, their use during pregnancy does not appear to have a significant effect on the prevention and treatment of gestational diabetes.

Resumo A disbiose intestinal pode contribuir para a patogénese da diabetes gestacional, encorajando o surgimento de novas abordagens de prevenção e tratamento baseadas no uso de probióticos. Esta revisão tem como objetivo elucidar as alterações do microbiota intestinal associadas à diabetes gestacional, a forma como estas contribuem para a sua fisiopatologia, os mecanismos de ação dos probióticos, e o seu papel na prevenção e tratamento da doença. A revisão da literatura mostrou que a diabetes gestacional está associada a um aumento de bactérias gram-negativas e a uma diminuição de bactérias gram-positivas produtoras de ácidos gordos de cadeia curta. Esta disbiose intestinal pode proporcionar alterações na homeostase da glicose através de mecanismos que envolvem a diminuição da secreção de incretinas e o aumento da inflamação. Embora a suplementação com probióticos melhore esta desregulação, a sua utilização durante a gravidez não parece ter um efeito significativo na prevenção e tratamento da diabetes gestacional.

ABSTRACT Introduction: Central adiposity as a triggering factor for early insulin resistance is a potential threat of metabolic and cardiovascular risk in pregnancy. Objective: To determine the discriminating capacity of abdominal fat over insulin resistance, diagnosed by the triglyceride/glucose-BMI index at the end of the first trimester of pregnancy. Methods: An analytical and observational study was carried out with 526 pregnant women of singleton pregnancy and gestational age between twelve and thirteen weeks, between 2016 and 2020. The triglyceride/glucose-BMI test was studied, together with abdominal fats by ultrasound. ROC (receiver operating characteristic) curves were used to discriminate insulin resistance at the end of the first trimester of gestation, when abdominal fats increase. Results: Subcutaneous fat presented the highest area under the curve in the discrimination of insulin resistance, with an acceptable level of sensitivity and specificity. Conclusions: Subcutaneous fat, although with low discriminative value, can be considered as a harbinger of insulin resistance and gestational diabetes. Further study of abdominal fat is required, given the knowledge of its impact on metabolic disorders in late gestation.

RESUMEN Introducción: La adiposidad central como factor desencadenante de resistencia a la insulina precoz constituye una amenaza potencial de riesgo metabólico y cardiovascular en el embarazo. Objetivo: Determinar la capacidad discriminante de las grasas abdominales sobre la resistencia a la insulina, diagnosticada por el índice triglicéridos/glucosa-IMC al finalizar el primer trimestre del embarazo. Métodos: Se realizó un estudio observacional analítico de 526 gestantes con embarazo simple y edad gestacional entre 12 y 13 semanas, entre los años 2016 y 2020. Se estudió el test de triglicéridos/glucosa-IMC y las grasas abdominales por ultrasonido. Se utilizaron las curvas ROC (Receiver operating characteristic Curve) para discriminar la resistencia a la insulina al finalizar el primer trimestre de la gestación, cuando aumentan las grasas abdominales. Resultados: La grasa subcutánea fue la que presentó mayor área bajo la curva en la discriminación de la resistencia a la insulina, con un nivel de sensibilidad y especificidad aceptable. Conclusiones: La grasa subcutánea, aunque con bajo valor discriminativo, puede considerarse como augurio de resistencia a la insulina y de diabetes gestacional. Se requiere profundizar en el estudio de las grasas abdominales dado el conocimiento de su impacto en los desórdenes metabólicos en el curso avanzado de la gestación.

Resumen Introducción: existen dos términos para describir el crecimiento fetal excesivo: “grande para la edad gestacional” (GEG) y “macrosomía”. GEG generalmente implica un peso al nacer superior al percentil 90 para una edad gestacional determinada. Objetivos: estimar la incidencia de recién nacidos GEG, y evaluar si la obesidad y la diabetes mellitus gestacional (DMG) son factores asociados. Materiales y métodos: estudio de cohorte retrospectivo de embarazadas -con y sin DMG- y sus recién nacidos vivos entre 2015 y 2018, evaluadas en el Hospital Italiano de la Ciudad Autónoma de Buenos Aires. La incidencia de recién nacidos GEG y de macrosomía se presentó como porcentajes e intervalos de confianza del 95% (IC 95%), así como sus complicaciones. Se utilizó regresión logística múltiple para evaluar si la DMG y la obesidad eran factores asociados a recién nacidos GEG. Resultados: la incidencia de GEG fue del 15,9% (IC 95%; 14,117,9) y de macrosomía del 6,7% (IC 95%; 5,5-8,1). La incidencia de recién nacidos GEG fue mayor en las mujeres con DMG y obesidad. La obesidad representó per se un mayor riesgo con y sin asociación con DMG. La obesidad, en presencia de DMG, incrementa la chance de recién nacidos GEG comparada con las mujeres sin DMG y sin obesidad (OR 2,41; p<0,001). Conclusiones: la DM y la obesidad materna incrementan el riesgo de GEG. Es importante implementar medidas preventivas e intervenciones en las mujeres en edad fértil con el objetivo de promover la salud de la madre y de su descendencia.

Abstract Introduction:two terms are used to describe excessive fetal growth: “large for gestational age” (LGA) and “macrosomia”. LGA generally implies a birth weight greater than the 90th percentile for a given gestational age. Objectives: to estimate the incidence of LGA newborns and to assess whether obesity and gestational diabetes mellitus (GDM) are associated factors. Materials and methods: retrospective cohort study of pregnant women with and without GDM and their live newborns between 2015-2018 evaluated at the Italian Hospital in the City of Buenos Aires, Argentina. The incidence of LGA and macrosomia newborns is presented as percentages and 95% confidence intervals (95% CI), as well as their complications. Multiple logistic regression was used to assess whether GDM and obesity are factors associated with LGA newborns. Results: the incidence of LGA was 15.9% (IC 95%; 14.1-17.9) and of macrosomia 6.7% (IC 95%; 5.5-8.1). The incidence of LGA newborns was higher in women with GDM and obesity. Obesity represented a higher risk per se with and without association with GDM. Obesity, in the presence of GDM, increases the chance of LGA newborns compared to women with GDM and without obesity (OR 2.41; p<0.001). Conclusions:diabetes and maternal obesity increase the risk of LGA. It is important to implement preventive measures and interventions on women of childbearing age with the aim of promoting the health of the mother and her offspring.

ABSTRACT Introduction: prenatal growth and development have their expression in birth weight, which acquires great importance due to its relationship with morbidity and mortality at any stage of life. Objective: to identify the associations of maternal variables with the trophic condition of the newborn. Methods: a descriptive study was carried out in three health areas from Santa Clara municipality between January 2013 and December 2020. A random sample of 2,454 was selected from a population of 6,035 newborns. Information on maternal and newborn variables was obtained. Non-parametric tests of independence based on the Chi-square distribution and Kruskal Wallis were applied in the statistical analysis. Results: the variables studied showed a relationship with the trophic condition at birth, except for age. Poor nutritional status was more frequent in small births and obesity in large ones. In large births, higher percentages of pregnant women at risk of gestational diabetes were observed. Hypertensive disorders, anemia, urinary tract infection, vaginal sepsis and smoking were present in higher percentages in pregnant women whose newborns were small. Conclusions: from the studied variables, the risk of gestational diabetes and hypertensive disorders showed the strongest association with the trophic status at birth.

RESUMEN Introducción: El crecimiento y desarrollo prenatal tiene su expresión en el peso al nacer, que adquiere gran importancia por su relación con la morbilidad y mortalidad en cualquier etapa de la vida. Objetivo: Identificar las asociaciones de variables maternas con la condición trófica del recién nacido. Métodos: Se realizó un estudio descriptivo, en tres áreas de salud del municipio Santa Clara, en el periodo comprendido de enero 2013 a diciembre 2020. De una población de 6035 recién nacidos se seleccionó una muestra aleatoria de 2454. De los libros de genética se obtuvo la información de variables maternas y del neonato. Se aplicaron las pruebas no paramétricas de independencia basada en la distribución chi cuadrado y Kruskal Wallis en el análisis estadístico. Resultados: A excepción de la edad, las variables estudiadas mostraron relación con la condición trófica al nacer. El estado nutricional deficiente fue más frecuente en nacimientos pequeños y el obeso en los grandes. En nacimientos grandes se observó mayores porcentajes de gestantes con riesgo de diabetes gestacional. Los trastornos hipertensivos, la anemia, la infección del tracto urinario, la sepsis vaginal y el hábito de fumar se presentaron en mayores porcentajes en gestantes cuyos recién nacidos fueron pequeños. Conclusiones: De las variables estudiadas el riesgo de diabetes gestacional y los trastornos hipertensivos mostraron la mayor fuerza de asociación con la condición trófica al nacer.

RESUMO Objetivos: Investigar o efeito do nível de hemoglobina A1c (HbA1c) na espessura macular central e na espessura da coróide central, nasal e temporal em pacientes com diabetes mellitus gestacional. Métodos: Este estudo retrospectivo incluiu 82 olhos de 41 pacientes diagnosticadas com diabetes mellitus gestacional, as quais fizeram um teste de tolerância oral à glicose de 75 g entre 24 e 28 semanas de gestação. As pacientes foram divididas em dois grupos de acordo com o nível de hemoglobina A1c (hemoglobina A1c <6,0% e hemoglobina A1c ≥6,0%). Todas as pacientes foram submetidas a exame oftalmológico completo e, a espessura macular central, a espessura central, nasal e temporal da coroide foram mensuradas por tomografia de coerência óptica. Resultados: Durante o período do estudo, das 3.016 gestantes triadas, 7,5% (n=228) foram diagnosticadas com diabetes mellitus gestacional. Destas, 41 pacientes foram analisadas de acordo com os critérios do estudo. Houve 48 olhos de 24 pacientes no primeiro grupo com hemoglobina A1c <6,0% e 34 olhos de 17 pacientes no segundo grupo com hemoglobina A1c ≥6,0%. Os valores médios do índice de massa corporal foram de 30,8 ± 3,3 e 35,1 ± 9,0, respectivamente (p=0,002). As taxas referentes ao uso de insulina foram de 29,2% e 76,5%, respectivamente (p=0,000). Os valores médios da espessura macular central foram medidos em 250,8 ± 14,3 µm e 260,9 ± 18,1 µm, respectivamente e a diferença foi significativa entre os dois grupos (p=0,008). Conclusões: Embora os valores do índice de massa corporal e da espessura macular central tenham sido significativamente maiores no Grupo 2 com hemoglobina A1c alta, não houve diferenças nas medidas de espessura coroidal central, nasal e temporal entre os dois grupos.

ABSTRACT Purpose: To investigate the effect of hemoglobin A1c level on central macular thickness and central, nasal, and temporal choroidal thickness in patients with gestational diabetes mellitus. Methods: This retrospective study included 41 patients who had been diagnosed with gestational diabetes mellitus and undergone a 75-g oral glucose tolerance test between 24 and 28 weeks of gestation. They were divided into two groups based on their hemoglobin A1c level (group 1: hemoglobin A1c <6.0% and group 2: hemoglobin A1c ≥6.0%). All patients underwent a complete ophthalmologic examination. The central macular thickness and central, nasal, and temporal choroidal thickness were measured using optical coherence tomography. Results: Of the 3,016 pregnant women screened, 7.5% (n=228) were diagnosed with gestational diabetes mellitus during the study period and 41 of these patients were included in the study. Group 1 comprised 48 eyes from 24 patients and Group 2 consisted of 34 eyes of 17 patients. The average body mass index values were 30.8 ± 3.3 and 35.1 ± 9.0, respectively (p=0.002). The insulin use rates were 29.2% and 76.5%, respectively (p=0.000). Mean central macular thickness values were 250.8 ± 14.3 µm and 260.9 ± 18.1 µm, respectively, and the difference was significant (p=0.008). Conclusions: Although the body mass index and central macular thickness values were significantly higher in Group 2, there was no difference in the central, nasal, and temporal choroidal thickness between the two groups.

Resumo Objetivos: descrever o perfil de utilização de medicamentos e de adesão, e a associação com as características clínicas e sociodemográficas de gestantes de alto risco atendidas em um hospital universitário. Métodos: trata-se de um estudo transversal com dados coletados mediante um questionário estruturado aplicado à 386 gestantes. Resultados: a maior parte das participantes era acompanhada apenas pelo ginecologista (75,1%), iniciou o pré-natal no primeiro trimestre gestacional (86,8%), não planejou a gravidez (61,9%) e realizou em média 8,2 (DP=4,4) consultas de pré-natal. Os diagnósticos mais frequentes foram hipertensão arterial (20,5%) e diabetes mellitus (19,7%). A prevalência de uso de medicamentos foi 99,7%, com média de 5,1 (DP=2,1) medicamentos por mulher e 12,7% de automedicação. Os antianêmicos (88,9%) e analgésicos (63,2%) foram as classes farmacológicas mais prevalentes e 17,9% das gestantes referiram uso de fármacos com risco gestacional relevante. Apenas 36,5% das gestantes foram consideradas aderentes ao tratamento, 32,9% declararam desconhecer a indicação dos medicamentos em uso e 42% não receberam orientações sobre o uso de medicamentos durante a gestação. Não há evidências de associação entre o número de medicamentos utilizados e os aspectos clínicos e sociodemográficos. Conclusão: é necessário desenvolver estratégias para melhorar o atendimento desta população e o uso racional de medicamentos, com ênfase no fortalecimento do cuidado multiprofssional.

Abstract Objectives: describe the profile of medication use and adherence, and the association with clinical and sociodemographic characteristics of high-risk pregnant women attended at a university hospital. Methods: cross-sectional study with data collected through a questionnaire applied on 386 pregnant women. Results: most participants were seen only by the gynecologist (75.1%), started prenatal in the first gestational trimester (86.8%), did not plan the pregnancy (61.9%), and performed an average of 8.2 (SD=4.4) prenatal consultations. The most frequent diagnoses were arterial hypertension (20.5%) and diabetes mellitus (19.7%). Prevalence of medication use was 99.7%, with an average of 5.1 (SD=2.1) medication per woman and 12.7% self-medication. Antianemics (88.9%) and analgesics (63.2%) were the most prevalent classes and 17.9% of the women reported the use of medication with significant gestational risk. Only 36.5% were considered adherent, 32.9% declared they were unaware of the indication of the medication in use and 42% did not receive guidance on the use of the medication during pregnancy. There is no evidence of association between the number of the medication used and clinical and sociodemographic aspects. Conclusions: there is a need to develop strategies to improve the care of this population, with emphasis on strengthening multi-professional care.

Resultados Idade materna avançada, gravidez gemelar e índice de massa corporal (IMC) mais elevado tornaram-se mais frequentes em 2018. Para mitigar o impacto dos fatores de confusão nas comparações entre os grupos, fizemos um ajuste por escores de propensão e detectamos diferenças significativas nas taxas de gravidez gemelar, diabetes mellitus gestacional e doença da tireoide. Conclusão Os dados do presente estudo podem ser utilizados para prevenir e melhorar o manejo de morbidades, impactando em melhores resultados na prática obstétrica.

Abstract Objective The present study seeks to identify the associated factors that increased primary cesarean delivery rates. Methods This was a cross-sectional study that evaluated the number of primary cesarean sections performed in the years 2006 and 2018 at the Hospital de Clínicas de Porto Alegre (HCPA, in the Portuguese acronym), through the collection of data from the medical records of the patients. Results Advanced maternal age, twin pregnancy, and higher body mass index (BMI) became more frequent in 2018 in comparison with 2006. To mitigate the impact of confounding in comparisons among groups, we made an adjustment by propensity scores and detected significant differences when comparing both age groups on twin pregnancy rates, gestational diabetes mellitus, and thyroid disease. Conclusion Data from the present study can be used to prevent and improve the management of morbidities, impacting on better outcomes in obstetrical practice.

Resumen Marco contextual: durante el embarazo se producen adaptaciones fisiológicas que pueden provocar cambios en el metabolismo materno, siendo fundamental la intervención del enfermero para mejorar la calidad de vida materno-fetal. Objetivo: desarrollar una propuesta de plan de cuidados de enfermería centrado en el embarazo gemelar, la diabetes gestacional y la restricción del crecimiento fetal. Metodología: estudio de caso referido a una paciente de 40 años que fue sometida a cesárea segmentaria transversal por restricción del crecimiento fetal 1 y diabetes mellitus. Para la recolección de datos se utilizó el Modelo Teórico de Nancy Roper y para la realización del plan de Atención de Enfermería se utilizó la taxonomía de la Clasificación Internacional para la Práctica de Enfermería y las intervenciones de enfermería sustentadas en la Clasificación de Intervenciones de Enfermería. Resultados: a partir de la evaluación inicial se identificaron doce diagnósticos de enfermería, de los cuales se optó por abordar los diagnósticos de enfermería.: 1. Ansiedad actual; 2. Cambio en el metabolismo energético. Conclusión: el rol de la enfermera es fundamental en las acciones educativas para promover la salud, en el sentido no solo de vigilancia sino también de continuidad del cuidado después del parto y también en el manejo de la ansiedad, ya que condiciona positivamente la transición al rol parental.

Abstract Background: during pregnancy, physiological adaptations occur that can cause changes in maternal metabolism, and the intervention of nurses is essential to improve maternal-fetal quality of life. Objective: to develop a proposal for a nursing care plan focusing on twin pregnancy, gestational diabetes, and fetal growth restriction. Methodology: case study referring to a 40-year-old female patient who underwent a transversal segmental cesarean due to fetal growth restriction 1 and diabetes mellitus. For data collection, the Theoretical Model of Nancy Roper was used and for the realization of the Nursing Care plan, the taxonomy of the International Classification for Nursing Practice and the nursing interventions supported by the Nursing Interventions Classification were used. Results: based on the initial assessment, twelve nursing diagnoses were identified, of which we chose to address nursing diagnoses: 1. Current anxiety; 2. Change in energy metabolism. Conclusion: the role of the nurse is fundamental in educational actions to promote health, in the sense not only of surveillance but also of continuity of care after childbirth and also in the management of anxiety, as it positively conditions the transition to the parental role.

Introduction: Leptin in maternal/fetal compartments, and its mechanisms, are being elucidated. Hormonal factors, genetic predisposition, chromosomal formation, environmental conditions, infections and the use of toxic substances may be related to negative outcomes in pregnancy, the fetus and the neonate. Objective: To analyze the correlation of placental leptin with maternal gestational factors and anthropometric data on the newborn. Method: Cross-sectional, descriptive, uncontrolled study. The sample consisted of 103 parturients and their respective newborns (NB). They were arranged according to the presented gestational risk factors and usual risk factors, and later, blood was collected from the placental fragments, for the serum leptin dosage. Gestational age, weight, height, BMI and head circumference were evaluated. Results: There was no statistically significant difference in leptin distribution below or above 0.1 in mothers with and without gestational risk factors. However, there was a trend in those with diabetes and obesity. Regarding the assessment of the presence and absence of maternal gestational factors between them and the level of placental leptin, only the obesity factor was significant. When the association between NB characteristics and leptin values was evaluated, no significant difference was observed; however, when related to gender, there was twice as much in females. In the assessment between weight/GA with placental leptin, there was no difference, but it was superior in big for gestational age NBs. Conclusion: Placental leptin was correlated with maternal gestational obesity risk, but without correlation with NB anthropometric data.

Introdução: lLeptina nos compartimentos materno/fetais, e seus mecanismos, estão sendo elucidados. Fatores hormonais, predisposição genética, formação cromossômica, condições ambientais, infecções e a utilização de substâncias tóxicas podem estar relacionadas a desfechos negativos na gestação, no feto e no neonato. Objetivo: Analisar a correlação da leptina placentária com fatores maternos gestacionais e dados antropométricos do recém-nascido. Método: Estudo transversal, descritivo, não controlado. A amostra constou de 103 parturientes e seus respectivos recém-nascidos (RN). As parturientes foram dispostas conforme os fatores de risco gestacionais apresentados e fatores de risco habituais, e posteriormente coletado sangue dos fragmentos placentários, para a dosagem sérica da leptina. Foram avaliados a idade gestacional, peso, estatura, IMC e perímetro cefálico. Resultados: Não houve diferença estatisticamente significativa na distribuição da leptina inferior ou superior a 0,1 em mães com e sem os fatores de risco gestacionais. No entanto verificou-se tendência naquelas com diabete e obesidade. Quanto à avaliação da presença e ausência de fatores maternos gestacionais entre si e o nível de leptina placentária, apenas o fator obesidade foi significante. Quando avaliada a associação entre as características do RN e os valores de leptina não foi observada diferença significativa; no entanto, houve quando relacionada ao gênero, o dobro no sexo feminino. Na avaliação entre peso/IG com leptina placentária não houve diferença, porém foi superior em RN’s grande para a idade gestacional. Conclusão: A leptina placentária apresentou correlação com o risco materno gestacional de obesidade, mas sem correlação com a antropometria do RN.

ABSTRACT Introduction: the frequency of infants experiencing growth restriction during intrauterine development is high and its highest incidence is in developing countries, among which Latin America and the Caribbean reach a prevalence of 10%. Objective: to identify the relationship among anemia, blood pressure changes and dysglycemia, with fetal growth restriction. Methods: we conducted a descriptive, retrospective and longitudinal study of pregnant women recruited in two health areas from Santa Clara municipality, who ended their pregnancy between September 2013 and October 2018 and in whom the newborns had intrauterine growth restriction. The sample was classified as small and adequate, according to their trophic condition at birth. The relation of these conditions in which a link with the restriction phenomenon was suspected was studied in each group. Results: children who had fetal growth restriction were classified, according to their trophic condition, as adequate; no significant relationships were found among anemia, gestational diabetes and arterial hypertension with the presence of intrauterine growth restriction. Conclusions: this condition was not related to the health of the pregnant women belonging to these two health areas from Santa Clara municipality.

RESUMEN Introducción: La frecuencia de infantes que durante el desarrollo intrauterino experimentan restricción del crecimiento es alta y su mayor incidencia está en los países en desarrollo, entre los que Latinoamérica y el Caribe alcanzan prevalencia del 10 %. Objetivo: Identificar la relación que existe entre la anemia, las alteraciones de la tensión arterial y la disglicemia, con la restricción del crecimiento fetal. Métodos: Se realizó estudio longitudinal descriptivo y retrospectivo de gestantes captadas en dos áreas de salud del municipio Santa Clara, que terminaron su embarazo entre septiembre del 2013 y octubre del 2018. Los recién nacidos presentaron restricción del crecimiento intrauterino. La muestra se clasificó en: pequeños y adecuados, según condición trófica al nacimiento. En cada grupo se estudió la relación de estas afecciones en los que se sospechó un vínculo con el fenómeno de restricción. Resultados: Los niños que presentaron restricción del crecimiento fetal se clasificaron, según su condición trófica, en adecuados; no se apreciaron relaciones significativas entre la anemia, la diabetes gestacional y la hipertensión arterial con la presencia de restricción del crecimiento intrauterino. Conclusiones: esta afección no estuvo relacionada con la salud de las gestantes portadoras en dos áreas de salud del municipio Santa Clara.

Resumen En las personas con diabetes mellitus (DM) e hipertensión arterial (HTA), los objetivos de presión arterial (PA) deben individualizarse considerando el riesgo cardiovascular, los potenciales efectos adversos de los fármacos antihipertensivos, y el costo y las preferencias de los pacientes. En personas con DM y elevado riesgo cardiovascular un objetivo de PA <130/80 mmHg sería apropiado si puede lograrse con seguridad. Si el riesgo cardiovascular es bajo, tartar la HTA con un objetivo <140/90 mmHg. En embarazadas con DM gestacional (DMG) e HTA preexistente, se sugiere un objetivo de PA de 110-135/85 mmHg con la finalidad de reducir el riesgo de eclampsia y minimizar el retraso de crecimiento intrauterino.

Abstract In patients with diabetes mellitus (DM) and hypertension (HP), blood pressure (BP) goals should be individualized considering cardiovascular risk, potential adverse effects of antihypertensive medications, cost, and patient preferences. In people with DM and high cardiovascular risk, a BP target <130/80 mmHg would be appropriate if it can be achieved safely. If cardiovascular risk is low, treat hypertension with a target <140/90 mmHg. In pregnant women with gestational diabetes mellitus (GDM) and preexisting hypertension, a BP target of 110-135/85 mmHg is suggested to reduce the risk of eclampsia and minimize intrauterine growth restriction.

ABSTRACT Introduction: gestational diabetes mellitus is the alteration of carbohydrate metabolism, of variable severity, that begins, or is recognized for the first time in pregnancy. Objective: to describe the incidence and risk factors of gestational diabetes mellitus at the Fe del Valle Ramos Gynecological-Obstetric Provincial Hospital in the period between 2015 and 2019. Methods: an observational study was carried out, conceived in two stages: a first one aimed at describing the main sociodemographic and clinical epidemiological aspects related to gestational diabetes mellitus in the population under study, and an analytical phase aimed at identifying the main risk factors associated with pregnant women. The information was collected through the medical records and hospital control registry of the studied patients. The information was processed using absolute and relative frequency distributions for its representation in tables and graphs. Results: it was shown that the main risk factors that mainly affected the presence of gestational diabetes mellitus, in the study patients were a history of gestational diabetes in previous pregnancies, a family history of diabetes mellitus in relatives of the first degree of consanguinity and overweight or maternal obesity. Conclusions: adequate prenatal care and regular and systematic monitoring of pregnant women allow the identification and timely diagnosis of patients at high risk of developing this disease.

RESUMEN Introducción: la diabetes mellitus gestacional es la alteración del metabolismo de los hidratos de carbono, de severidad variable, que comienza o se reconoce por primera vez en el embarazo después de las 24 semanas. Objetivo: describir la incidencia y los factores de riesgo de la diabetes mellitus gestacional en el Hospital “Fe del Valle Ramos” en el período comprendido entre los años 2015 y 2019. Métodos: se realizó un estudio observacional retroprospectivo concebido en dos etapas: una primera destinada a describir los principales aspectos sociodemográficos y clínico epidemiológicos relacionados con la diabetes mellitus gestacional en la población objeto de estudio, y una fase analítica destinada a identificar los principales factores de riesgo asociados a las gestantes. La recolección de la información se realizó a través de las historias clínicas y el registro de control hospitalario de las pacientes estudiadas. Se procesó la información utilizando distribuciones de frecuencias absolutas y relativas para su representación en tablas y gráficos. Resultados: se demostró que los principales factores de riesgo que mayormente incidieron en la presencia de la diabetes mellitus gestacional en las pacientes en estudio fueron los antecedentes de diabetes gestacional en embarazos previos, los antecedentes familiares de diabetes mellitus en familiares de primer grado de consanguineidad y el sobrepeso o la obesidad materna. Conclusiones: una atención prenatal adecuada y un seguimiento periódico y sistemático de la mujer embarazada permiten la identificación y el diagnóstico oportuno de pacientes con alto riesgo de desarrollar esta enfermedad.

ABSTRACT Introduction: Gestational diabetes mellitus presents a series of complications for both the pregnant woman and her child, which can increase morbidity in pregnant women or the offspring. Objective: To determine the risk factors associated with gestational diabetes mellitus. Methods: A descriptive, retrospective and cross-sectional study was carried out with patients with the aforementioned diagnosis, belonging to the community of Pedro Borras Astorga University Polyclinic, Pinar del Rio Cuba, during the years 2014 to 2018. From a universe of 1623 pregnant women attended in the studied period, a sample of 59 pregnant women with gestational diabetes mellitus was taken. Descriptive statistics was used. The results were shown in tables and graphs. Results: The incidence of the disease was 3.6%, ages were between 26 and 30 years, and there were no adolescents diagnosed in the period studied. Previous history included abortions and nulliparity. Transpelvic delivery prevailed, while the short-term complications of the child were macrosomia, neonatal hypoglycemia and shoulder dystocia. There was no perinatal death caused by the studied condition. Conclusions: Gestational diabetes mellitus is associated with some risk factors, which may lead to complications for the mother and the in the perinatal period.

RESUMEN Introducción: La diabetes mellitus gestacional presenta una serie de complicaciones en la mujer embarazada y su hijo, lo cual puede incrementar la morbilidad en las gestantes o la descendencia. Objetivos: Determinar los factores de riesgo asociados a la diabetes mellitus gestacional. Métodos: Se realizó un estudio descriptivo, retrospectivo y transversal de las pacientes con este diagnóstico, perteneciente a la comunidad del Policlínico Universitario “Pedro Borrás Astorga”, Pinar del Río, durante los años 2014 al 2018. De un universo de 1623 mujeres embarazadas atendidas en el período estudiado, se tomó una muestra de 59 gestantes con diabetes mellitus gestacional. Se utilizó la estadística descriptiva. Los resultados se presentaron en tablas y gráficos. Resultados: La incidencia de la enfermedad fue de un 3,6 %, en edades entre 26-30 años, no hubo adolescentes diagnosticadas en el período estudiado. Como antecedentes previos estuvieron los abortos y la nuliparidad. Prevaleció el parto transpelviano y las complicaciones a corto plazo del hijo fueron: la macrosomía, la hipoglucemia neonatal y la distocia de hombro. No hubo muerte perinatal causada por este padecimiento. Conclusiones: La diabetes mellitus gestacional se relaciona con algunos factores de riesgo, lo que puede provocar complicaciones para la madre y el feto en el período perinatal.
