Factores de riesgo psicosocial asociados con la diabetes mellitus gestacional: revisión sistemática / Psychosocial risk factors associated with gestational diabetes mellitus: systematic review

La diabetes mellitus gestacional DMG es una enfermedad con consecuencias mortales, incapacitantes y costosas para las personas, las familias, las comunidades y los países. Con el fin de establecer de manera sistemática los factores de riesgo psicosocial asociados con la DMG que deberían ser monitoreados durante y después del embarazo se realizó una revisión sistemática en las bases de datos PubMed/Medline y Cochrane. Se encontraron 1188 artículos y se seleccionaron 41. Algunos temas principales fueron conflictos con prácticas culturales, estigma social, influencia de la etnia/raza, bajo nivel educativo, calidad del sueño, problemas con la lactancia materna, preocupación por la propia salud o la del bebé, baja percepción de riesgo de DMG o de diabetes mellitus tipo 2 en el futuro, estrés, ansiedad y depresión, conocimiento limitado, falta de apoyo de la pareja, de la familia o social y de los profesionales de la salud, bajos niveles de autocuidado/autoeficacia y dificultades con cambios en el estilo de vida. Estos factores deberían monitorearse en las embarazadas durante y después del parto. Los tratamientos deberían considerar el impacto psicológico y el riesgo de desarrollar diabetes mellitus tipo 2 después del parto, y deberían ser incluidos en las guías de práctica clínica. Las poblaciones multiétnicas y los grupos más vulnerables demográficamente y socioeconómicamente son más susceptibles de desarrollar DMG.

Gestational diabetes mellitus (GDM) is a disease with fatal, disabling, and costly consequences for individuals, families, communities and countries. To systematically establish the psychosocial risk factors associated with GDM that should be monitored during and after pregnancy. Systematic review in PubMed/Medline and Cochrane databases. 1188 articles were found and 41 were selected. Some main themes were conflicts with cultural practices, social stigma, ethnicity/race influence, low educational level, sleep quality, breastfeeding problems, concern for ones own health/baby, low perception of the risk of GDM/DM2 in the future, stress, anxiety and depression, limited knowledge, lack of support from the partner/family/social and health professionals, low levels of self-care/self-efficacy and difficulties with changes in the lifestyle. These factors should be monitored in pregnant women during and after delivery. Treatments should consider the psychological impact and the risk of developing DM2 after childbirth and should be included in clinical practice guidelines. Multi-ethnic populations and the most demographically and socioeconomically vulnerable groups are more susceptible to developing GDM.

Diabetes gestacional autorreferido - uma análise da Pesquisa Nacional de Saúde / Self-reported gestational diabetes - an analysis of the National Health Survey

Resumo Introdução O diabetes mellitus gestacional é definido como qualquer grau de intolerância à glicose, diagnosticado pela primeira vez durante a gestação, podendo ou não persistir após o parto. Sua prevalência ainda é conflitante, mas os riscos oferecidos a mãe e feto são diversos. Objetivo Identificar as respostas positivas de mulheres sobre um diagnóstico de diabetes recebido na gestação e relacioná-lo a características sociodemográficas e do pré-natal, além de descrever as orientações recebidas frente ao diagnóstico. Método Estudo com característica transversal que utiliza dados da Pesquisa Nacional de Saúde 2013, conforme o autorrelato de diagnóstico de diabetes gestacional. Realizou-se análise bivariada e cálculo das prevalências e razões de prevalência, com intervalo de confiança de 95% (IC95%), considerando plano de amostragem complexa. Resultados O diagnóstico de diabetes mellitus gestacional no período pré-natal foi relatado por 106 mulheres, com uma prevalência ponderada de 6,6% (IC95% 5,0-8,5). Verificou-se associação entre o relato de diagnóstico na gestação com maior idade e cor não branca. A maioria das mulheres diagnosticadas recebeu orientações quanto aos riscos da doença, mas poucas foram encaminhadas para consulta com especialista. Conclusão Os resultados detalhados da PNS fornecem estimativas populacionais sobre a magnitude da doença e possibilitam identificar o conjunto de fatores associados ao DMG.

Abstract Background Gestational diabetes mellitus is defined as any degree of glucose intolerance that is first diagnosed during pregnancy and may or may not persist after delivery. Its prevalence is still conflicting, but the risks offered to mother and fetus are diverse. Objective To identify the positive responses of women about a diagnosis of diabetes received during pregnancy and to relate it to sociodemographic and prenatal characteristics, in addition to describing the orientations received regarding the diagnosis. Method A cross-sectional study that uses data from the 2013 National Health Survey according to the self-reported gestational diabetes diagnosis. A bivariate analysis was performed, and prevalence and prevalence rates with a 95% confidence interval (95% CI) were calculated, considering a complex sampling plan. Results The diagnosis of prenatal gestational diabetes mellitus was reported by 106 women, with a weighted prevalence of 6.6% (95% CI 5.0-8.5). There was an association between the diagnosis report in older pregnancy and non-white color. Most diagnosed women received guidance on the risks of the disease, but few were referred for specialist consultation. Conclusion The detailed results of the PNS provide population estimates of the magnitude of the disease and make it possible to identify the set of factors associated with GDM.

Evaluación del polimorfismo Pro12Ala del gen PPARƴ en mujeres con diabetes mellitus gestacional / Evaluation of the Pro12Ala polymorphism of the PPARƴ gene in women with gestational diabetes mellitus

Resumen OBJETIVO: Determinar la frecuencia del alelo Ala en una muestra de mujeres mexicanas con diabetes mellitus gestacional y asociar su repercusión en la glucemia. MATERIALES Y MÉTODOS: Estudio ambispectivo, observacional, transversal y correlacional efectuado en una cohorte de pacientes con diabetes gestacional atendidas entre los meses de enero a junio del 2014 en el Hospital Militar de Especialidades de la Mujer y Neonatología de la Secretaría de la Defensa Nacional en la Ciudad de México. Se evaluó el polimorfismo mediante amplificación de un fragmento de ADN mediante la reacción en cadena de la polimerasa (PCR) y su secuenciación. RESULTADOS: Se estudiaron 81 pacientes; 3 de ellas con el alelo Ala, con concentraciones de glucosa menores y antecedente de más abortos en comparación con las mujeres sin el alelo Ala. CONCLUSIONES: La coexistencia del alelo Ala en mujeres embarazadas con diagnóstico de diabetes mellitus gestacional pudiera tener un efecto protector en contra de la hiperglucemia en el embarazo y el riesgo de aborto.

Abstract OBJECTIVE: To determine the frequency of peroxisomal proliferator-activated receptor gamma (PPARg) polymorphism of proline substituted with an alanine in amino acid 12 (Pro12Ala), in women with gestational diabetes mellitus and associate its impact with glycemia. MATERIALS AND METHODS: An ambispective, observational, cross-sectional and correlational study was carried out in a cohort of women with gestational diabetes that included 81 pregnant women treated at the Military Hospital for Women's Specialties and Neonatology of the Ministry of National Defense in the city from Mexico. Polymorphism was evaluated by amplification of a DNA fragment by PCR Polymerase Chain Reaction and its sequencing. RESULTS: The results indicated that 13.5% of the women carriers of the Ala allele also had lower blood glucose values and a history with a higher number of abortions compared to women without the Ala allele. CONCLUSIONS: The presence of the Ala allele in pregnant women with gestational diabetes mellitus could have a protective effect against hyperglycemia in pregnancy and a risk of abortion.

Factores psicosociales asociados con la diabetes mellitus gestacional: Revisión sistemática de alcance / Psychosocial factors associated with gestational diabetes mellitus: Systematic review of scope

Resumen Objetivo: Hacer una revisión sistemática de alcance sobre los factores psicosociales asociados con la diabetes mellitus gestacional (DMG) para mejorar las intervenciones preventivas, evitar sus complicaciones y mejorar la calidad de vida de las mujeres embarazadas. Materiales y métodos: Se realizó una revisión sistemática con base a la metodología PRISMA en bases de datos PubMed/Medline y Cochrane sobre estudios de factores psicosociales en mujeres embarazadas, mayores de 18 años, con diagnóstico de DMG, publicadas en el periodo 2010 al 2020, en revistas revisadas por pares en cualquier idioma. La extracción de datos se hizo con un formulario estandarizado. Resultados: La búsqueda arrojó 1787 artículos, de los cuales se seleccionaron 102 según criterios de inclusión. Se encontraron como temas principales: conflictos con prácticas culturales, estigma social, influencia de la etnia/raza, bajo nivel educativo, calidad del sueño, limitaciones físicas, problemas con lactancia materna, preocupación por la propia salud/ bebé, baja percepción del riesgo de DMG y DM2 en el futuro, estrés/ansiedad/depresión, conocimiento limitado sobre DMG, falta de apoyo de la pareja/familia/social, bajos niveles de autocuidado/autoeficacia en el control glucémico, falta de apoyo de los profesionales de la salud y dificultades con los cambios en el estilo de vida. Conclusiones: Los factores psicosociales identificados deben integrarse a los programas de prevención y promoción existentes o en nuevas intervenciones. Las intervenciones no deberían finalizar con el embarazo si se tiene en cuenta el riesgo de desarrollar DM2 después del parto. Es necesario abordar las necesidades de poblaciones multiétnicas y grupos vulnerables demográfica y socioeconómicamente. Los factores psicosociales asociados con la DMG deberían incluirse también en el desarrollo de futuras Guías de Práctica Clínica.

Abstract Objective: To carry out a systematic review of scope on the psychosocial factors associated with gestational diabetes mellitus (GDM) to improve preventive interventions, avoid its complications and improve the quality of life of pregnant women. Materials and methods: A systematic review was carried out based on the PRISMA methodology in PubMed/Medline and Cochrane databases on studies of psychosocial factors in pregnant women, older than 18 years, with a diagnosis of GDM, published in the period 2010 to 2020, in peer-reviewed journals in any language. Data extraction was done using a standardized form. Results: The search yielded 1787 articles, of which 102 were selected according to inclusion criteria. The main themes were found: conflicts with cultural practices, social stigma, influence of ethnicity/race, low educational level, quality of sleep, physical limitations, problems with breastfeeding, concern for one's own health/baby, low perception of the risk of GDM and DM2 in the future, stress/anxiety/depression, limited knowledge about GDM, lack of partner/family/social support, low levels of self-care/self-efficacy in glycemic control, lack of support from health professionals and Difficulty with lifestyle changes. Conclusions: The identified psychosocial factors should be integrated into existing prevention and promotion programs or new interventions. Interventions should not terminate pregnancy if the risk of developing DM2 after delivery is taken into account. The needs of multi-ethnic populations and demographically and socioeconomically vulnerable groups need to be addressed. Psychosocial factors associated with GDM should also be included in the development of future Clinical Practice Guidelines.

Incidencia de recién nacidos grandes para la edad gestacional y su asociación con diabetes mellitus gestacional y obesidad maternas. Estudio de cohorte en un hospital de Buenos Aires / Incidence of large-for-gestational-age newborns and its association with maternal gestational diabetes mellitus and obesity. Cohort study in a hospital in Buenos Aires

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.

Evaluation of the relationship between HbA1c level and retina choroidal thickness in patients with gestational diabetes mellitus / Avaliação da relação entre o nível de HbA1c e a espessura coroidal da retina em pacientes com diabetes mellitus gestacional

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: 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.

Hemoglobina glucosilada en el diagnóstico de diabetes gestacional en mujeres mexicanas durante el tercer trimestre / Glycosylated hemoglobin in the diagnosis of gestational diabetes in Mexican women during the third trimester

Resumen El objetivo del trabajo fue analizar los valores de hemoglobina glucosilada en el tercer trimestre de embarazo como predictores alternativos de la diabetes gestacional en pacientes del Noreste de México. Se trata de un estudio retrospectivo de casos y controles a partir de 121 expedientes de pacientes embarazadas, divididos en dos grupos, pacientes con diabetes gestacional (casos) y gestantes con valores glucémicos normales (controles). Se analizaron los factores de riesgo asociados a la diabetes gestacional y se obtuvo un punto de corte para la hemoglobina glucosilada. Se encontró que la obesidad materna, la edad y el antecedente del padecimiento fueron asociados significativamente con la diabetes gestacional. Valores de hemoglobina glucosilada ≥5% incrementaron el riesgo de padecer diabetes mellitus gestacional 4 veces y, aunado a un factor de riesgo, la probabilidad se incrementó 7 veces. Se concluye que los valores de hemoglobina glucosilada en el tercer trimestre de embarazo podrían emplearse como prueba diagnóstica de la diabetes gestacional en pacientes del Noreste de México. Sin embargo, aunque las diferencias encontradas fueron estadísticamente significativas, los resultados se deben interpretar con cautela y requieren su confirmación con estudios que incluyan una muestra mayor.

Abstract The objective of this study was to analise glycosylated hemoglobin values in the third trimester of pregnancy as an alternative predictor of gestational diabetes in North East Mexican cohort patients. This is a retrospective case-control study based on 121 records of pregnant patients, divided into two groups, patients with gestational diabetes (cases) and pregnant women with normal glycemic values (control). The risk factors associated with gestational diabetes were analised and a cut-off point for glycosylated hemogestaglobin was obtained. It was found that maternal obesity, age and a history of the condition were significantly associated with gestational diabetes. Values of glycosylated hemoglobin ≥5% increased the risk of suffering from gestational diabetes 4 times, and coupled with a risk factor, the risk increased 7 times. It is concluded that glycosylated hemoglobin values in the third trimester of pregnancy could be used as a diagnostic test for gestational diabetes in patients from the North East of Mexico. Although the differences found were statistically significant, our results must be interpreted with caution and require confirmation by studies with a larger sample.

Resumo O objetivo deste estudo foi analisar os valores da hemoglobina glicada no terceiro trimestre de gestação como preditores alternativos do diabetes gestacional em pacientes na região nordeste do México. Trata-se de um estudo retrospectivo de casos e controles utilizando 121 prontuários de gestantes divididas em dois grupos; pacientes com diabetes gestacional (casos) e gestantes com valores de glicemia normais (controles). Foram analisados os fatores de risco associados a diabetes gestacional obtendo-se um ponto de corte para a hemoglobina glicada. Descobriu-se que a obesidade materna, idade e antecedentes da doença foram associados significativamente ao diabetes gestacional. Valores da hemoglobina glicada ≥ 5% aumentaram o risco de padecer diabetes mellitus gestacional 4 vezes, e juntamente a um fator de risco, a probabilidade aumentou 7 vezes. Conclui-se que os valores da hemoglobina glicada no terceiro trimestre de gestação poderiam ser usados como teste diagnóstico do diabetes gestacional em pacientes da região nordeste do México. Embora as diferenças encontradas tenham sido estatisticamente significativas, os resultados devem ser interpretados com cautela e requerem confirmação através de estudos que incluam uma amostra maior.

Comparative analysis between prevention and treatment costs for gestational diabetes mellitus in primary and tertiary health care in a city in Southern Brazil / Análise comparativa entre os custos de prevenção e tratamento do diabetes mellitus gestacional na assistência à saúde primária e terciária em uma cidade do Sul do Brasil

Objective: The present study's purpose is to evaluate the economic context in which the Brazilian public health system, the only universal public health system with more than 200 million users, stands out. This evaluation will be made through the lens of the execution of gestational health care services in a city of approximately 500 thousand inhabitants in southern Brazil. The care costs of patients with gestational diabetes mellitus (GDM) will be compared to those of patients without GDM, analyzing the different economic valuation methods. And lastly, there was an intent to explore the generated costs in the context of economic valuation applied to health to comprehend better the complexity of the union of the financial and health areas to optimize the services offered. Methods: For the economic context in health, an analysis of health investments was performed through the Transparency Portal. The costs involved in preventing GDM were raised by the Sistema Único de Saúde (SUS) table of procedures performed ordinarily in low-risk pregnancies. The expenses involved in DMG patients were increased at the High-Risk Pregnancy and Fetal Medicine Clinic of DMG patients. Results: Preventing GDM is more cost-effective, cost-minimizing, and cost-useful than treating patients diagnosed with GDM. Conclusion: The result is an extremely interesting costopportunity, given the economic context in which it is presented

Objetivo: O presente estudo tem como objetivo avaliar o contexto econômico em que se encontra o sistema público de saúde brasileiro, único sistema público universal de saúde com mais de 200 milhões de usuários. Essa avaliação será feita sob a ótica da execução de serviços de saúde gestacional em um município de aproximadamente 500 mil habitantes no Sul do Brasil. Os custos assistenciais de pacientes com diabetes mellitus gestacional (DMG) serão comparados aos de pacientes sem DMG, analisando os diferentes métodos de valoração econômica. Também serão analisados os custos gerados no contexto da valoração econômica aplicada à saúde para uma melhor com preensão da complexidade da união das áreas econômica e da saúde com o objetivo de otimizar os serviços oferecidos. Métodos: Para a contextualização econômica em saúde, foi feita a análise dos investimentos em saúde pelo Portal da Transparência. Os custos envolvidos na prevenção da DMG foram levantados pela tabela de procedimentos realizados ordinariamente em gestações de baixo risco do Sistema Único de Saúde (SUS). Os custos envolvidos em pacientes com DMG foram levantados no Ambulatório de Gestação de Alto Risco e Medicina Fetal de pacientes com DMG. Resultados: Prevenir o DMG apresenta maiores custo-benefício, custo-efetividade, custo-minimização e custo-utilidade em comparação com o tratamento das pacientes com o diagnóstico de DMG. Conclusão: O resultado é um custo-oportunidade extremamente interessante, dado o contexto econômico em que se apresenta

Condição bucal de mulheres com diabetes mellitus gestacional internadas em um hospital escola no sul do Brasil / Oral condition of women with gestational diabetes mellitus admitted in a school hospital in southern Brazil

Objetivo: avaliar a condição bucal de mulheres com diabetes mellitus gestacional (DMG) internadas no Hospital Escola (HE) da Universidade Federal de Pelotas (UFPel). Métodos: trata-se de um estudo transversal retrospectivo de base hospitalar, em que dois residentes treinados realizaram a coleta dos dados por meio da avaliação dos prontuários médicos e odontológicos, no período de setembro de 2019 a março de 2020. Os dados socioeconômicos e demográficos e o diagnóstico de DMG foram coletados dos prontuários médicos, enquanto hábitos e condição bucal, dos prontuários odontológicos. A análise dos dados foi realizada no programa Stata 11.0, usando os testes Exato de Fisher e Regressão de Poisson. Resultados: foram avaliados os prontuários de 83 gestantes, destas, 37 (44,6%) apresentavam DMG. A presença de DMG esteve asso-ciada com as gestantes de maior faixa etária (62,2%) e no terceiro trimestre de gestação. Em sua maioria, tinham renda de até dois salários mínimos, eram solteiras, tinham filhos e realizaram pré-natal. Em relação à avaliação bucal, apenas a presença de cálculo dental e inflamação gengival foi estatisticamente associada à presença de DMG (p= 0,030 e 0,014 respectivamente). A autopercepção do sorriso foi considerada ruim por 40,5%, e a maioria teve dentes perdidos por cárie (64,9%). Conclusões: a prevalência de DMG foi alta entre as gestantes internadas, sendo maior em mulheres de mais idade. Presença de cálculo dental e inflamação gengival foram fortemente associadas à presença de DMG, enquanto hábitos bucais e presença de cárie não apresentaram associação. Novas pesquisas, com exames periodontais completos, são necessárias para verifi-car as condições periodontais dessas mulheres.(AU)

Aim: to assess the oral condition of women with Gestacional Diabetes Mellitus (GDM) admitted in a School Hospital (HE)/UFPel. Methods: medical and dental records, from September 2019 to March 2020, were evaluated in this hospital-based retrospective cross-sectional study. Socioeconomic and demographic data were collected from medical records, while oral condition and habits were obtained from the dental records. Statistical analysis was performed with Stata 11.0 software using Fisher's exact test and Poisson regression. Results: the medical records of 83 pregnant women were evaluated, of which 37 (44.6%) had GDM. The presence of GDM was associated with pregnant women of older age (62.2%) and most in the third trimester of pregnancy. Most of them had an income of up to two minimum wages, were single, had children and underwent prenatal care. Regarding the oral evaluation, only the presence of dental calculus and gingival inflammation was statistically associated with the presence of GDM (p = 0.030 and 0.014 respectively). The self-perception of the smile was considered bad to 40.5% and many of them had lost teeth due to caries (64.9%). Conclusions: the prevalence of GDM was high in hospitalized pregnant women, being higher in older women. Presence of dental calculus and gingival inflammation were strongly associated with the presence of GDM, while oral habits and the presence of caries were not associated. Further research, with complete periodontal examinations is necessary to verify the periodontal conditions of these women.(AU)

Expression of ADAMTS13 and PCNA in the placentas of gestational diabetic mothers / Expresión de ADAMTS13 y PCNA en las placentas de madres diabéticas gestacionales

SUMMARY: GDM is linked with overexpression of inflammatory cytokines and increased oxidative stress, leading to endothelial dysfunction and vascular disorder. Weaimed to examine the expression of ADAMTS13 and PCNA in the placentas of gestational diabetes mellitus (GDM) patients to investigate the effects of hypoxia, induced by GDM, on proliferation and extracellular matrix formation in the maternal and fetal placenta cells. A total of 60 placentas were collected from pregnant women admitted to the obstetrics clinic. Thirty of them were diagnosed with GDM, and 30 of them were diagnosed with non-GDM patients. Samples were fixed in 10 % formaldehyde, after routine follow-up, embedded in paraffin wax. Sections of 5 µm were cut stained with Mayer Hematoxylin-Eosin, examined under a light microscope. Sections for immunohistochemical analysis were cut and processed for antigen retrievalin citrate solution. Sections were incubated with ADAMTS13 and PCNA primary antibodies, counterstained with hematoxylin, and evaluate under a light microscope. In histopathological examination, the non-diabetic placentas showed that decidua cells in the maternal region were polygonal with oval nuclei and organized in groups. In the GDM group, there were pyknosis and apoptotic changes in decidua cell nuclei. Vacuolar areas were observed in large cavities in maternal connective tissue. Inflammation and dilatation with congestion were observed in the blood vessels of the villus. In the GDM group, positive ADAMTS13 expression was observed in the decidua cells vascular endothelial cells, and surrounding connective tissue fibroblast cells. In the GDM group, a significant increase in PCNA expression was observed in decidua cells, connective tissue cells and endothelial cells. Functional changes in ADAMTS13 proteases and PCNA were thought to induce maternal and fetal complications by stimulating extracellular matrix development.

RESUMEN: La diabetes gestacional está relacionada con la sobreexpresión de citocinas inflamatorias y aumento del estrés oxidativo, lo que lleva a una disfunción endotelial y un trastorno vascular. Nuestro objetivo fue examinar la expresión de ADAMTS13 y PCNA en las placentas con diabetes mellitus gestacional (DMG) para investigar los efectos de la hipoxia inducida por DMG sobre la proliferación y formación de matriz extracelular en células placentarias maternas y fetales. Se recolectaron un total de 60 placentas de mujeres embarazadas ingresadas a la consulta de obstetricia. Treinta de ellas fueron diagnosticadas con DMG y 30 diagnosticadas sin DMG. Las muestras se fijaron en formaldehído al 10 %, y luego de un seguimiento de rutina, fueron embebidas en parafina. Se cortaron secciones de 5 µm teñidas con hematoxilina-eosina de Mayer, las que fueron examinadas bajo un microscopio óptico. Se cortaron y procesaron las secciones para el análisis inmunohistoquímico para la recuperación de antígeno en solución de citrato. Las secciones se incubaron con anticuerpos primarios ADAMTS13 y PCNA, se contratiñeron con hematoxilina y se evalua- ron con un microscopio óptico. En el examen histopatológico, las placentas no diabéticas mostraron que las células de la decidua en la región materna eran poligonales con núcleos ovalados y organizadas en grupos. En el grupo de DMG, se observó picnosis y cambios apoptóticos en los núcleos de las células de la decidua. Se observaron áreas vacuolares en el tejido conectivo materno. En los vasos sanguíneos de las vellosidades se observó inflamación y dilatación con congestión. En el grupo de DMG, se observó expresión positiva de ADAMTS13 en las células de la decidua, en las células endoteliales vasculares y en los fibroblastos del tejido conectivo circundante. En el grupo de DMG se observó un aumento significativo de la expresión de PCNA en células de la decidua, células de tejido conectivo y en las células endoteliales. Se considera que los cambios funcionales en las proteasas ADAMTS13 y PCNA inducen a complicaciones maternas y fetales al estimular el desarrollo de la matriz extracelular.

Conclusión: Las estrategias de tamizaje para identificar ECV en mujeres con antecedentes de PE y DMG reportadas por los MG fueron variables.

Abstract Introduction: Cardiovascular disease (CVD) is the leading cause of mortality in women; preeclampsia (PE) and gestational diabetes mellitus (GDM) are associated with an increased risk of CVD. Objective: To evaluate general practitioners (GP) knowledge about complicated pregnancies and their association with CVD. Methods: An anonymous case-based electronic questionnaire designed to assess the level of understanding on the influence of a history of pregnancy complications on long-term cardiovascular risk and general knowledge about CVD risk was sent to GPs. Results: The response rate was 35 % (161/465). The participants recognized that PE and GDM are risk factors for CVD (98 and 83 %, respectively), and reported the following CVD screening strategies in women with a history of PE and GDM: blood pressure monitoring (PE 100 %, GDM 46 %), body mass index calculation (PE 68 %, GDM 57 %), lipid profile evaluation (PE 71 %, GDM 57 %), glycated hemoglobin (PE 26 %, GDM 92 %), and fasting glucose (PE 28 %, GDM 91 %). Conclusion: GP-reported screening strategies to identify CVD in women with a history of PE and GDM were variable.

Tratamento para o diabetes mellitus gestacional: uma revisão de literatura / Treatment for gestational diabetes mellitus: a literature review

O diabetes mellitus gestacional (DMG) é uma complicação que atinge o metabolismo da gestante, resultando em intolerância à glicose e consequente hiperglicemia, originada pela insuficiência de insulina materna. Este estudo tem como objetivo identificar os tratamentos disponíveis e mais utilizados para o DMG. Trata-se de um uma revisão de literatura, feita a partir de 22 referências, acerca dos tratamentos para o DMG. As bases de dados escolhidas foram Google Acadêmico, UpToDate, SciELO e o acervo da Universidade do Planalto Catarinense. Estudos apontam a insulina humana ­ NPH e regular ­ como a principal escolha, quando comparada aos seus análogos, apesar de ainda existirem muitas controvérsias quanto ao início do tratamento, o esquema terapêutico e os ajustes das doses. Pesquisas têm demonstrado bons resultados sobre a eficácia e a segurança dos hipoglicemiantes orais ­ gliburida e metformina ­ no tratamento de gestantes diabéticas, mas é evidente a necessidade de mais estudos para confirmar a efetividade deles e garantir um bom desenvolvimento do concepto. Concluiu-se que o controle dietético e o exercício físico são a primeira opção de tratamento para o DMG. Todavia, caso a euglicemia não seja atingida, opta-se pelo tratamento medicamentoso por meio da insulinoterapia ou hipoglicemiantes orais, o que possibilita a redução da incidência dos efeitos adversos ao binômio materno-fetal.(AU)

Gestational diabetes mellitus (DMG) is a complication that affects the pregnant woman's metabolism, resulting in glucose intolerance and consequent hyperglycemia, caused by insufficient maternal insulin. This study aims to identify the available and most used treatments for DMG. This is a literature review, based on 22 references, about treatments for Gestational Diabetes; the databases chosen were Google Scholar, UpToDate, SciELO and the collection of the Universidade do Planalto Catarinense. Studies point to human insulin ­ NPH and regular ­ as the main choice when compared to its analogues, although there are still many controversies about the beginning of treatment, therapeutic scheme and dose adjustments. Researches have shown good results on the efficacy and safety of oral hypoglycemic agents ­ glyburide and metformin ­ in the treatment of diabetic pregnant women, but it is evident the need for further studies to confirm their effectiveness and to guarantee a good development of the fetus. It was concluded that dietary control and physical exercise are the first treatment option for DGM. However, if euglycemia is not achieved, drug treatment is chosen through insulin therapy or oral hypoglycemic agents, which makes it possible to reduce the incidence of adverse effects to the maternal-fetal binomial.(AU)

Anemia no diabetes mellitus gestacional: implicações na instabilidade genômica / Anemia in gestational diabetes mellitus: implications for genomic instability

Introdução: Evidências têm mostrado uma associação entre anemia e Diabetes Mellitus. Contudo, a relação entre anemia e Diabetes Mellitus Gestacional (DMG) ainda não está bem estabelecida, bem como sua repercussão na instabilidade genômica. Portanto, objetivou-se verificar a associação entre anemia e instabilidade genômica em mulheres com DMG atendidas em um hospital universitário. Métodos: Estudo transversal com mulheres apresentando diagnóstico de DMG que realizaram pré-natal no Hospital Universitário de Santa Maria (RS). Informações referentes ao DMG, anemia e suplementação de ferro foram obtidas nos prontuários. A instabilidade genômica foi avaliada pelo ensaio de citoma em micronúcleos em células bucais (BMCyt). Resultados: Das 44 gestantes avaliadas, 28,6% apresentaram anemia e 79,5% foram suplementadas com ferro. Das gestantes que realizaram suplementação, 75,0% não apresentaram anemia gestacional. Níveis de hemoglobina não se associaram com a instabilidade genomica (p > 0,05), mas foi observada uma associação entre brotos nucleares e os níveis de glicemia (r = 0,977; p = 0,003). Conclusão: Não foi verificado associação entre anemia e instabilidade genômica em mulheres com DMG.(AU)

Introduction: There is evidence of an association between anemia and diabetes mellitus. However, the relationship between anemia and gestational diabetes mellitus (GDM) remains to be established, as well as its impact on genomic instability. Therefore, we aimed to examine the association between anemia and genomic instability in women with GDM treated at a university hospital. Methods: A cross-sectional study of women with a diagnosis of GDM who received prenatal care at the University Hospital of Santa Maria, southern Brazil. Data on GDM, anemia, and iron supplementation were obtained from medical records. Genomic instability was assessed by the buccal micronucleus cytome (BMCyt) assay. Results: Of 44 pregnant women evaluated, 28.6% had anemia and 79.5% received iron supplementation; of the latter, 75.0% did not have gestational anemia. Hemoglobin levels were not associated with genomic instability (p > 0.05), but an association was found between nuclear buds and blood glucose levels (r = 0.977; p = 0.003). Conclusion: There was no association between anemia and genomic instability in women with GDM.(AU)

Status de vitamina d y marcadores de metabolismo óseo en diabetes gestacional

RESUMEN Introducción y objetivos: La deficiencia de vitamina D (VD) ha sido asociada con alteración del metabolismo glucémico y síndrome metabólico. Datos actuales sugieren que tendría un rol en la prevención de diabetes gestacional y pre eclampsia. El presente estudio fue diseñado para evaluar los niveles de vitamina D en embarazadas con diabetes mellitus gestacional (DMG) y su relación con los niveles de fructosamina, parathormona, marcadores del metabolismo óseo y control metabólico. Materiales y métodos: Se incluyeron 44 embarazadas con diagnóstico de DMG, entre 15 y 45 años de edad. Las variables analíticas que se determinaron fueron: fructosamina, 25- hidroxivitamina D (25-OH-VD), Parathormona (PTH), calcio total, calcio iónico, fosforo y calcio corregido por albúmina. Resultados: Se analizaron los niveles de 25-OH-VD según las estaciones del año. El valor promedio fue de 37 ng/ml en verano, 26 ng/ml en otoño, 24 ng/ml en primavera y 17 ng/ml en invierno. Se evidenció una relación inversa entre VD y PTH (p<0.014). La correlación entre VD e índice de masa corporal (IMC) revelo un valor promedio de VD de 32.27 ng/ml en grupo con IMC <30 versus 23.63 ng/ml en el grupo con IMC >30 (p<0.027). Se observó relación inversa entre VD y fructosamina (p 0,479). Conclusión: La prevalencia de deficiencia de VD durante el embarazo debe ponerse a consideración en vista de las potenciales implicancias clínicas sobre la salud materna, fetal y postnatal, especialmente cuando se asocia a otros factores de riesgo como sobrepeso, obesidad y diabetes mellitus gestacional.

ABSTRACT Introduction and objectives: Vitamin D deficiency has been associated with altered glycemic metabolism and metabolic syndrome. New data suggest that it might have a role in prevention of gestational diabetes mellitus and preeclampsia. The present study was designed to analyze the relationship between vitamin D with parathormone levels, bone turn over markers and metabolic control. Methodology: The sample consisted of 44 pregnant women with gestational diabetes mellitus, ages 15-45, who attended to endocrinology external consultation. The variables analyzed were 25-hydroxivitan D, parathormone, fructosamine, total calcium, ionic calcium, calcium corrected by albumin and phosphorus, also, the relationship with body mass index, season of the year and age. Results: 25-hydroxivitamin D levels were analyzed regarding the season of the year; the average value was 37 ng/ml in summer, 26 ng/ml in autumn, 24 ng/ml in spring and 17 ng/ml in winter. There was an inverse relationship between vitamin D and parathormone (p<0.014). The analysis regarding vitamin D and BMI revealed the following values, 32.27 ng/ml for BMI <30 and 23.63 ng/ml for BMI >30 (p<0.027). There was an inverse relationship between Vitamin D and fructosamine (p 0.479). Conclusions: The prevalence of Vitamin D deficiency during pregnancy must be taken into account because of the implications in multiple aspects of maternal, fetal and postnatal health, especially when it is associated with other risk factors as overweight, obesity and gestational diabetes mellitus.

Assessment of polymorphismof the vdr gene and serum vitamin d values in gestational diabetes mellitus / Avaliação do polimorfismo do gene VDR e valores séricos de vitamina D no diabetes mellitus gestacional

Abstract Objective To evaluate the relationship between vitamin D receptor (VDR) gene polymorphism (FokI [rs10735810]) and serum vitamin D concentration in gestational diabetes mellitus (GDM). Methods A prospective case-control study that recruited healthy pregnant women (control group) (n = 78) and women with GDM (GDM group) (n = 79), with no other comorbidities. Peripheral blood samples were collected in the 3rd trimester of gestation, and all of the pregnant women were followed-up until the end of the pregnancy and the postpartum period. Serum vitamin D concentrations were measured by high-performance liquid chromatography (HPLC). For genomic polymorphism analysis, the genomic DNA was extracted by the dodecyltrimethylammonium bromide/ cetyltrimethylammonium bromide (DTAB/CTAB) method, and genotyping was performed by the polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) technique, using the restriction enzyme FokI. The Student-t, Mann- Whitney, chi-squared, and Fischer exact tests were used for the analysis of the results. Results There was no significant difference between the pregnant women in the control and GDM groups regarding serumvitamin D levels (17.60 ± 8.89 ng/mL versus 23.60 ± 10.68 ng/mL; p = 0.1). Also, no significant difference was detected between the FokI genotypic frequency when the 2 groups were compared with each other (p = 0.41). Conclusion There was no association between the FokI polymorphism and the development of GDM, nor was there any change in serum vitamin D levels in patients with GDM.

Resumo Objetivo Avaliar a relação entre o polimorfismo do gene receptor da vitamina D (VDR) (FokI [rs10735810]) e a concentração sérica de vitamina D no diabetes mellitus gestacional (DMG). Métodos Estudo prospectivo tipo caso-controle que recrutou gestantes saudáveis (grupo controle) (n = 78) e com DMG (grupo DMG) (n = 79), sem outras comorbidades. Foram coletadas amostras de sangue periférico no 3° trimestre da gestação, e todas as gestantes foram acompanhadas até o final da gravidez e no pós-parto. As concentrações séricas de vitamina D foram mensuradas por cromotografia líquida de alta eficiência (CLAE). Para análise do polimorfismo genético, o DNA genômico foi extraído pelo método de brometo de dodeciltrimetilamônio/brometo de cetiltrimetilamônio (DTAB/CTAB), e as genotipagens foram realizadas por técnica de reação de cadeia de polimerase - polimorfismo do comprimento do fragmento de restrição (PCRRFLP, na sigla em inglês), sendo empregada a enzima de restrição FokI. Foram utilizados os testes t-Student, Mann-Whitney, qui-quadrado e exato de Fischer para a análise dos resultados. Resultados Não houve diferença significativa entre as gestantes dos grupos controle e DMG quanto aos níveis séricos de vitamina D (17,60 ± 8,89 ng/mL versus 23,60 ± 10,68 ng/mL; p = 0,1). Também não foi detectada diferença significativa entre a frequência genotípica de FokI, quando comparados os 2 grupos entre si (p = 0,41). Conclusão Não foi identificada associação do polimorfismo FokI com o desenvolvimento de DMG, bem como não foi observada alteração nos níveis séricos de vitamina D em pacientes com DMG.

Profile of pregnant women with gestational diabetes mellitus at increased risk for large for gestational age newborns / Perfil de gestantes com diabetes mellitus gestacional com maior risco para recém-nascidos grandes para a idade gestacional

Abstract Objective Gestational diabetes mellitus (GDM) is associated with a higher risk of perinatal morbidity and mortality, and its main complication is the occurrence of large for gestational age (LGA) newborns. The present study aims to characterize pregnant women with GDM and to identify factors associated with the occurrence of LGA newborns in this population. Methods A cross-sectional study was performed based on medical records of women whose prenatal care and delivery were performed at the Maternal and Child Unit of the HospitalUniversitário of theUniversidade Federal doMaranhão, state of Maranhão, Brazil.A total of 116 pregnant women diagnosed with GDMwere included according to the criteria of the International Association of Diabetes and Pregnancy Study Groups (IADPSG). Results The variables associated with LGA newborns after multivariate analysis were: obesity prior to pregnancy (OR = 11.6; 95% CI: 1.40-95.9), previous macrosomia (OR = 34.7; 95% CI: 4.08-295.3), high blood glucose levels in the 3rd trimester (OR = 2,67; 95% CI: 1.01-7.12) and combined change in the oral glucose tolerance test (OGTT) (fasting + postdextrose) (OR = 3.53;95%CI:1.25-14.2) = 1.17-10.6).Otherwise, insufficientweight gain during pregnancy reduced the risk for LGA newborns (OR = 0.04; 95% CI: 0.01-0.32). Conclusion Obesity prior to pregnancy, previous macrosomia, high blood glucose levels in the 3rd trimester, and combined change in the OGTT were independent predictive factors for LGA newborns in pregnant women with GDM.

Morphological features of the human placenta and its free chorionic villi in normal pregnancies and those with diabetes and high blood pressure: literature review / Características morfológicas de la placenta humana y sus vellosidades coriales libres en gestas normales y con diabetes e hipertensión arterial: revisión de la literatura

The most prevalent pathologies during pregnancy, such as hypertension, gestational diabetes mellitus (GDM), and intrauterine growth restriction (IUGR), can determine modifications in macro- and microscopic morphological features of the placenta and its free chorionic villi. In the fetus it may be accompanied by pathological manifestations, with the embryo's future quality of life, and even its viability, at risk. The aim of this work is to perform a review of the morphological alterations that the placenta exhibits in pregnancies with GDM. A search on the topic in the scientific literature and specialized textbooks was carried out. The terms "placenta", "diabetes mellitus gestational" and "gestational diabetes mellitus" were used to define the search. Among the morphological modifications it was found that the placental weight/fetal weight ratio is higher in GDM and is associated mainly with histological changes. The distance between maternal and fetal circulation is increased because of an increase in the chorionic villi on the surface as well as greater thickness of the syncytiotrophoblast basal membrane due to an increased type IV collagen deposition. The stroma between the villi is edematous, which modifies the metabolic and endocrinal function of these placentas. Moreover, the capillary surface is enlarged due to the phenomena of vascular neoformation and a greater penetration of these vessels within the villi. Low oxygen partial pressure (pO2) was detected, which would produce a compensatory hyperplasia of terminal chorionic villi. In GDM the placenta undergoes alterations in its formation, structure, and function. According to the review, these alterations are related to an oxygenation deficiency in the fetus and changes in the transplacental transport of nutrients and other alterations, causing fetal overgrowth by increasing their availability in addition to other consequences to the developing fetus. In the case of high blood pressure during pregnancy, this produces accelerated maturation and rapid aging of the chorionic villi, with the risk of inducing a placental abruption. In addition, placental circulation is reduced by a third, decreasing oxygen saturation in the umbilical vessels and placing the health of the fetus at risk.

Las patologías de la gestación más prevalentes, como hipertensión, diabetes mellitus gestacional (DMG) y restricción del crecimiento uterino, pueden determinar modificaciones en las características morfológicas macro y microscópicas de la placenta y sus vellosidades coriales libres,y en el feto se puede acompañar de manifestaciones patológicas, con riesgo para su calidad de vida futura, e incluso su viabilidad. El objetivo de este trabajo consiste en realizar una revisión acerca de las alteraciones morfológicas que presenta la placenta en gestaciones con DMG. Se llevó a cabo una búsqueda sobre la temática en literatura científica y libros de texto especializados. Se utilizaron los términos "placenta", "diabetes mellitus gestacional" y "gestational diabetes mellitus" para orientar la búsqueda. Entre las modificaciones morfológicas se encontró que la relación peso placentario/peso fetal está aumentado en la DMG y se asocia principalmente a cambios histológicos. La distancia entre la circulación materna y la fetal está aumentada debido a un aumento de la superficie entre las vellosidades coriales, así como al mayor grosor de la membrana basal del sincitiotrofoblasto por un depósito elevado de colágeno tipo IV. El estroma entre las vellosidades se encuentra edematoso lo que va a modificar la función metabólica y endocrina de estas placentas. También hay aumento de la superficie capilar por fenómenos de neoformación vascular y una mayor penetración de estos vasos dentro de las vellosidades. Se detectó baja presión parcial de oxígeno (pO2), que produciría una hiperplasia compensatoria de vellosidades coriónicas terminales. En la DMG la placenta experimenta alteraciones en su formación, estructura y función. Según lo revisado, estas alteraciones están relacionadas con déficit en la oxigenación del feto, cambios en el transporte transplacentario de los nutrientes y otras alteraciones, ocasionando sobrecrecimiento fetal por aumento de su disponibilidad, entre otras consecuencias al feto en desarrollo. Y en el caso de la hipertensión arterial durante la gestación produce una maduración acelerada y envejecimiento rápido de las vellosidades coriales, con el riesgo de inducir un desprendimiento prematuro de placenta. Además se reduce la circulación placentaria en un tercio, disminuyendo la saturación de oxígeno en los vasos umbilicales del, poniendo en riesgo la salud del feto.

Aspectos morfocuantitativos de las vellosidades coriales libres en gestas normales, con diabetes, hipertensión arterial y restricción del crecimiento intrauterino / Morphoquantitative characteristics of free corial vellosities in normal births, with diabetes, hypertension and restriction of intrauterine growth

Las patologías de la gestación como la hipertensión, diabetes mellitus gestacional, o restricción del crecimiento intrauterino, pueden determinar modificaciones en las características morfológicas macro y microscópicas de la placenta y sus vellosidades coriales libres, y en el feto se puede acompañar de manifestaciones patológicas, con riesgo para su calidad de vida futura, e incluso su viabilidad. El objetivo de este trabajo consistió en describir aspectos morfométricos e histológicos de las vellosidades coriales libres en gestas normales, con diabetes e hipertensión arterial. Se utilizaron 30 placentas humanas y fueron separadas, según presencia o ausencia de patologías en el embarazo, en tres grupos: Normal (N), Síndrome Hipertensivo del Embarazo (SHE), Diabetes (D) y Restricción del Crecimiento Intrauterino (RCIU). Se usó ficha para registrar peso placentario y del recién nacido Todas las muestras fueron fijadas en formalina tamponada al 10 %. De cada una fueron extraídas 5 muestras, obteniendo 25 cortes por cada placenta. Posteriormente, fueron teñidas con H&E, Azul Alcián y Tricrómico de Masson. Además, se efectuó el análisis histológico y morfométrico (ImageJ®) de las vellosidades coriales. El análisis estadístico fue realizado utilizando ANOVA. Entre los cambios morfológicos, se encontró una relación peso placentario/peso del recién nacido aumentada en la Diabetes Mellitus Gestacional asociada a cambios histológicos. No hubo cambios morfométricos significativos entre placentas N, SHE y D. Hubo un aumento en el número de vasos coriales en placentas del grupo D (P < 0,05) y de la superficie entre las vellosidades coriales. En el grupo SHE hubo aumento moderado de nudos sinciciales y presencia de fibrina en el estroma. Las placentas con Diabetes Mellitus Gestacional experimentan alteraciones histológicas, como consecuencia de cambios estructurales y funcionales. Además, el aumento de vasos sanguíneos en placentas con diabetes se produce por neoformación vascular y mayor penetración de vasos sanguíneos dentro de las vellosidades. En el caso del SHE las alteraciones placentarias se relacionan con la gravedad de la enfermedad.

Gestational pathologies such as hypertension, gestational diabetes mellitus and restriction of intrauterine growth can determine changes in the macro and microscopic morphological characteristics of the placenta and its free chorionic villi. In the fetus it can be accompanied by pathological manifestations with risk to its viability and future quality of life. The aim of this work was to describe morphometric and histological aspects of free chorionic villi in normal pregnancies associated with diabetes, hypertension and restriction of intrauterine growth. Thirty human placentas were used and were separated into three groups: Normal (N), Hypertensive Pregnancy Syndrome (SHE), Diabetes (D), and Restriction of Intrauterine Growth (RIG) according to evident pathologies or absence thereof during pregnancy. Tab was used to record placental and newborn weight. All samples were fixed in 10 % buffered formalin. From each, 5 samples were extracted, obtaining 25 cuts for each placenta. Subsequently, they were stained with H & E, Alcian Blue and Masson's Trichrome. In addition, histological and morphometric analysis (ImageJ®) of the chorion villus was carried out. Statistical analysis was performed using ANOVA. Among the morphological changes, an increased placental weight / weight ratio of the newborn was found in Gestational Diabetes Mellitus associated with histological changes. There were no significant morphometric changes between placentas N, SHE and D. There was an increase in the number of corial vessels in placentas of group D (P <0.05) and of the surface between the chorion villi. In the SHE group there was a moderate increase in syncytial nodes and presence of fibrin in the stroma. Placentas with Gestational Diabetes Mellitus experience histological alterations, as a consequence of structural and functional changes. In addition, the increase of blood vessels in placentas D is produced by vascular neoformation and increased penetration of blood vessels into the villi. In the case of SHE, placental alterations are related to the severity of the disease.
