RESUMEN
Objective: Evaluate the prevalence of macrosomic newborns (birth weight above 4000 grams) in a high-risk maternity from 2014 to 2019, as well as the maternal characteristics involved, risk factors, mode of delivery and associated outcomes, comparing newborns weighing 4000-4500 grams and those weighing above 4500 grams. Methods: This is an observational study, case-control type, carried out by searching for data in hospital's own system and clinical records. The criteria for inclusion in the study were all patients monitored at the service who had newborns with birth weight equal than or greater than 4000 grams in the period from January 2014 to December 2019, being subsequently divided into two subgroups (newborns with 4000 to 4500 grams and newborns above 4500 grams). After being collected, the variables were transcribed into a database, arranged in frequency tables. For treatment and statistical analysis of the data, Excel and R software were used. This tool was used to create graphs and tables that helped in the interpretation of the results. The statistical analysis of the variables collected included both simple descriptive analyzes as well as inferential statistics, with univariate, bivariate and multivariate analysis. Results: From 2014 to 2019, 3.3% of deliveries were macrosomic newborns. The average gestational age in the birth was 39.4 weeks. The most common mode of delivery (65%) was cesarean section. Diabetes mellitus was present in 30% of the deliveries studied and glycemic control was absent in most patients. Among the vaginal deliveries, only 6% were instrumented and there was shoulder dystocia in 21% of the cases. The majority (62%) of newborns had some complication, with jaundice (35%) being the most common. Conclusion: Birth weight above 4000 grams had a statistically significant impact on the occurrence of neonatal complications, such as hypoglycemia, respiratory distress and 5th minute APGAR less than 7, especially if birth weight was above 4500 grams. Gestational age was also shown to be statistically significant associated with neonatal complications, the lower, the greater the risk. Thus, macrosomia is strongly linked to complications, especially neonatal complications.

OBJECTIVE: To evaluate the iodine sufficiency of pregnant women assisted in a University Hospital of Minas Gerais, and to correlate the urinary concentrations of maternal iodine with the fetal thyroid hormone levels at birth. METHODS: Urinary iodine concentrations from 30 pregnant women with a singleton pregnancy and gestational age lower than 20 weeks were analyzed. Occasional samples of the mothers' urine were collected for the urinary iodine concentration dosage, and these were correlated with the newborns' thyroid-stimulating hormone (TSH) levels. RESULTS: The median iodine urinary concentration of this study's pregnant women population was 216.73 mcg/l, which is proper for the group, following the World Health Organization (WHO). No cases of neonatal hypothyroidism were reported in the study, which corroborates the iodine sufficiency in this population sample. CONCLUSION: This study shows that despite the increased demand for iodine from pregnant women and the Brazilian Health Regulatory Agency (ANVISA) recommendation of 2013 for reduction of salt iodization levels, the population of pregnant women attended in the prenatal ambulatory of normal risk from the Federal University of Minas Gerais is considered sufficient in iodine. As a higher sample is necessary for the confirmation of these findings, it is too early to recommend the universal supplementation of iodine for Brazilian pregnant women, and more studies must be carried out, considering that iodine supplementation for pregnant women in an area of iodine sufficiency is associated to the risks of the fetus's excessive exposure to iodine.
OBJETIVO: Avaliar a suficiência iódica de gestantes atendidas em um Hospital Universitário de Minas Gerais e correlacionar as concentrações urinárias de iodo materno com os níveis de hormônios tireoidianos fetais ao nascimento. MéTODOS: Foi analisada a concentração urinária de iodo de 30 gestantes com gestação única e idade gestacional menor que 20 semanas. Foram coletadas amostras ocasionais de urina materna para dosagem da concentração urinária de iodo, e estas foram correlacionadas com os níveis de hormônio estimulante da tiroide (TSH) dos recém-nascidos. RESULTADOS: A mediana da concentração urinária de iodo das gestantes estudadas foi de 216,73 mcg/L, sendo adequada para o grupo segundo a Organização Mundial de Saúde (OMS). Não houve nenhum caso de hipotireoidismo neonatal no estudo, o que corrobora a suficiência de iodo nesta amostra populacional. CONCLUSãO: Esse estudo demonstra que apesar do aumento da demanda de iodo pelas gestantes e da recomendação da Agência Nacional de Vigilância Sanitária (ANVISA) de 2013 da redução dos níveis de iodação do sal, a população de gestantes atendidas no ambulatório de pré-natal de risco habitual da Universidade Federal de Minas Gerais é considerada suficiente em iodo. Apesar de uma maior amostragem ser necessária para a confirmação destes achados, é cedo para recomendar a suplementação universal de iodo para as gestantes brasileiras e mais estudos precisam ser realizados, levando-se em conta que a suplementação de iodo para gestantes em áreas suficientes em iodo está associada aos riscos da exposição excessiva de iodo ao feto.

OBJECTIVE: Determine the predictive criteria for success in inducing labor for live fetuses using misoprostol in pregnant women. Secondarily, the objective is to determine the rates of vaginal or cesarean delivery, duration of induction, interval of administration of misoprostol, the main causes of induction of labor and indication for operative delivery. METHODS: Medical records of 873 pregnant women admitted for cervical maturation from January 2017 to December 2018 were reviewed in a descriptive observational study of retrospective analysis, considering the following response variables: age, parity, Bishop Index, doses of misoprostol, labor induction time. Logistic regression models were used to predict success with misoprostol in non-operative deliveries. RESULTS: Of the 873 patients evaluated, 72% evolved with vaginal delivery, 23% of the cases were cesarean, 5% forceps or vacuum-extractor. For non-operative delivery the predictive variables at admission were age, parity, gestational age and dilation. During hospitalization, fewer vaginal touches, amniotomy or amniorrhexis with clear fluid lead to a shorter induction time and a greater chance of non-operative delivery. False positives and false negatives of the model were always below 50% and correct answers above 65%. CONCLUSION: At admission, age less than 24 years, previous normal births, lower the gestational age and greater the dilation, were predictive of greater probability of non-operative delivery. During hospitalization, the less vaginal touches and occurrence of amniotomy/amniorrhexis with clear liquid indicate shorter induction time. Future studies with a prospective design and analysis of other factors are necessary to assess the replicability, generalization of these findings.

Em segundo lugar, o objetivo é determinar as taxas de parto vaginal ou cesáreo, duração da indução, intervalo de administração de misoprostol, as principais causas de indução do trabalho de parto e indicação para parto operatório. MéTODOS: Foram revisados os prontuários de 873 gestantes internadas para amadurecimento cervical entre janeiro de 2017 e dezembro de 2018 em um estudo descritivo observacional de análise retrospectiva, considerando as variáveis-resposta: idade, paridade, Índice de Bishop, doses de misoprostol, tempo de indução do trabalho de parto. Modelos de regressão logística foram utilizados para prever o sucesso com misoprostol em partos não operatórios. RESULTADOS: Dos 873 pacientes avaliados, 72% evoluíram com parto vaginal, 23% dos casos foram cesáreos, 5% fórceps ou vácuo-extrator. Para o parto não operatório as variáveis preditivas na internação foram idade, paridade, idade gestacional e dilatação. Durante a internação, um menor número de toques vaginais, amniotomia ou amniorrexe com líquido claro, levam a menor tempo de indução e maior chance de parto não operatório. Falsos positivos e falsos negativos do modelo sempre foram inferiores a 50% e respostas corretas acima de 65%. CONCLUSãO: Na internação, idade menor que 24 anos, ocorrência de partos normais anteriores, menor idade gestacional e maior dilatação, foram preditivos de maior probabilidade de parto não-operatório. Durante a internação, o menor número de toques vaginais, amniotomia/amniorrexe com líquido claro indicam menor tempo de indução. Estudos futuros com design prospectivo e análise de outros fatores são necessários para avaliar a replicabilidade, generalização desses achados.

OBJECTIVE: To assess the predictive abilities of serum and urinary cystatin C levels for glomerular lesions in pregnant women with pre-eclampsia. METHODS: In this study, kidney function markers were compared between38 pregnant women with pre-eclampsia and 22 healthy pregnant women. RESULTS: The serum and urine levels of cystatin C and urea were significantly higher in the pre-eclampsia group than in the control group. Receiver operating characteristic curve analysis demonstrated that the serum cystatin C level (91.7%) had a superior diagnostic accuracy for pre-eclampsia than the other markers. CONCLUSION: Serum cystatin C level maybe a significant marker of pre-eclampsia.

Resumo A constatação de que o feto é portador de malformação congênita enquadra-se como má notícia, e sua comunicação à gestante envolve conflitos éticos relativos à medicina fetal e neonatologia. A quebra de expectativas dos pais quanto ao filho idealizado desperta sentimentos antagônicos, e o modo de processar a notícia e até mesmo a eventual decisão de interromper a gestação podem ser diretamente influenciados pela forma como o fato é comunicado pela equipe. Para os casos em que a criança nasce com vida, a decisão de iniciar cuidados paliativos também deve ser compartilhada, viabilizando o exercício da parentalidade responsável. Contudo, é comum que a família solicite distanásia e obstinação terapêutica, quando não adequadamente esclarecida sobre o prognóstico da doença. São discutidos no estudo aspectos relacionados à adequada comunicação na relação médico-paciente, fundamental ao exercício da autonomia e ao dever de informar, cuja violação é passível de responsabilização nas esferas cível e ético-profissional.
Abstract The communication to the pregnant woman that her fetus has congenital abnormality is framed by what is meant by bad news, surrounded by ethical conflicts experienced in fetal medicine and neonatology. The couple's breach of expectations about their idealized child arouses antagonistic feelings; The manner of elaboration of the news and even the eventual decision to terminate the pregnancy will be directly influenced as the fact was communicated by the team. For cases in which the child is born alive, the decision to adopt Palliative Care should also be shared, providing the exercise of responsible parenting. It is common, however, the request by the family of practices that configure dysthanasia and therapeutic obstinacy, when not adequately clarified about the prognosis of the disease. Aspects related to proper communication in the physician-patient relationship are discussed, fundamental to the exercise of autonomy and the duty to inform, whose violation leads to liability in the civil and ethical-professional spheres.
Resumen La constatación de que el feto sufre una malformación congénita se enmarca en lo que se entiende por malas noticias, y su comunicación a la gestante implica conflictos éticos relativos a la medicina fetal y a la neonatología. La frustración de las expectativas de la pareja sobre su hijo idealizado despierta sentimientos antagónicos, y la manera de procesar la noticia e incluso la eventual decisión de interrumpir el embarazo pueden ser directamente influenciadas por la manera en que el equipo comunica el hecho. Para los casos en que el niño nace con vida, la decisión de adoptar cuidados paliativos también debe compartirse, para hacer viable el ejercicio de la parentalidad responsable. Sin embargo, es común que la familia solicite la distanasia y la obstinación terapéutica, cuando no se le aclara adecuadamente sobre el pronóstico de la enfermedad. En este estudio se discuten aspectos relacionados con la comunicación adecuada en la relación médico-paciente, fundamental al ejercicio de la autonomía y al deber de informar, cuya violación es pasible de responsabilidad civil y ético-profesional.

The emergence of nitroimidazole resistant isolates has been an aggravating factor in the treatment of trichomoniasis, the most common non-viral sexually transmitted disease in the world. This highlights the importance of new technologies that are safe, effective, and have minor side effects or resistance. Hence, we evaluated the effectiveness of photodynamic therapy on the inactivation of Trichomonas vaginalis in vitro. We used methylene blue as a photosensitizing substance, and a light-emitting diode (LED) for irradiation of metronidazole sensitive and resistant strains. Our results showed that only the presence of light did not interfere with parasite growth; however, methylene blue isolated or associated with light inhibited 31.78%⯱â¯7.18 and 80.21%⯱â¯7.11 of the sensitive strain, respectively, and 31.17%⯱â¯4.23 and 91.13%⯱â¯2.31 of the resistant strain, respectively. The high trichomonicidal activity of the photodynamic therapy, associated with low cost and ease of application, signalize its great therapeutic potential not only when conventional treatment fails, but also routinely in women with trichomoniasis.

The aim of this study was to evaluate the immunocytochemistry (ICC) to diagnose trichomoniasis, particularly asymptomatic infections. By culture serial dilutions, ICC was able to detect 1 trophozoite/mL, while the culture was positive up to 100 trophozoites/mL. The ICC in vivo detection capability was assessed in vaginal secretions of mice experimentally infected and in vaginal swabs from asymptomatic HIV-positive pregnant women compared with culture. All vaginal secretion samples from mice were positive according to both methods. Swabs from fifty-five asymptomatic women were positive in four (7.27%) of them by culture. Beyond these four, another ten (25.45%) women were positive by immunocytochemistry, proving their higher sensitivity (p = 0.002), noticing 3.5 times more positives. ICC had better performance in both successive dilutions as in asymptomatic women, showing higher sensitivity and specificity. In this way, its facility of execution and cost-effectiveness support its practicality, as a routine procedure to diagnose trichomoniasis not only when the parasite load is lower but probably in all clinical scenarios.

BACKGROUND: Cesarean section is a surgical procedure the main complication of which is surgical site infection (SSI), which is related to maternal morbidity and mortality. OBJECTIVE: To evaluate active monitoring by telephone to identify infection and time of SSI report in postpartum women and associated risk factors. METHODS: We conducted a prospective observational study from 2013-2014, at a referral service for high-risk pregnancies. Surveillance was conducted via telephone at least 30 days after cesarean delivery. Incidence ratio and time of infection occurrence (days) was analyzed. Survival analysis was conducted to assess the temporal distribution of the development of infection. RESULTS: Of a total of 353 patients, 14 (4%) cases of SSI were reported, and 10 (7.4%) of the reported cases occurred within 15 days after cesarean and average time of infection was12.21 days. American Society of Anesthesiologists score was the only risk factor associated with SSI after cesarean section. CONCLUSIONS: The prevalence of SSI after cesarean section via telephone is similar to several services with different methods of surveillance, considering it could be used by services with limited resources. Superficial incisional SSI was the most common type of infection, time of infection report was mainly before the 15th day postprocedure, and American Society of Anesthesiologists score of 2 or less was protective against SSI. Telephone calls can be a viable method to identify women with infection briefly after discharge, particularly at-risk patients.

Suicide is one of the major causes of preventable death. We evaluated suicidality among pregnant women who participated in prenatal care in Brazil. A total of 255 patients were assessed using semi-structured interviews as well as the Edinburgh Postnatal Depression Scale (EPDS), Beck Depression Inventory (BDI), and Mini-International Neuropsychiatric Interview (MINI) Plus. Thereafter, Stata 12 was used to identify the significant predictors of current suicide risk (CSR) among participants using univariate and multivariate analyses (p < 0.05). According to MINI Plus module C, the lifetime suicide attempt rate was 12.55%. The overall CSR was 23.53%, distributed across risk levels of low (12.55%), moderate (1.18%), and high (9.80%). Our rates approximate those found in another Brazilian study (18.4%). Antenatal depression (AD), lifetime bipolar disorder, and any current anxiety disorder (as measured using the MINI) as well as BDI scores ≥15 and EPDS scores ≥11 were identified as positive risk factors in a univariate analysis (p < 0.001). These factors changed after a multivariate analysis was employed, and only years of education [odds ratio (OR) = 0.45; 95% confidence intervals (CIs) = 0.21-0.99], AD (OR = 3.42; 95% CIs = 1.37-8.53), and EPDS scores ≥11 (OR = 4.44; 95% CIs = 1.97-9.97) remained independent risk factors. AD and other psychiatric disorders were the primary risk factors for suicidality, although only the former remained an independent factor after a multivariate analysis. More than 10 years of education and EPDS scores ≥11 were also independent factors; the latter can be used as a screening tool for suicide risk.

Introdução: a fisiopatologia da pré-eclâmpsia (PE) baseia-se em deficiência no processo de placentação, associada à disfunção endotelial sistêmica materna. A investigação da ocorrência desses fenômenos, antes do aparecimento das manifestações clínicas da PE, pode constituir-se em novo método propedêutico para sua predição. Objetivos: comparar o processo de placentação e a função endotelial de gestantes de alto risco para desenvolvimento de PE, correlacionando esses achados com o seu desenvolvimento posterior. Pacientes e métodos: 74 gestantesforam submetidas ao exame de dilatação fluxomediada (DFM) da artéria braquial e dopplerfluxometria das artérias uterinas para avaliação da função endotelial e do processo de placentação, respectivamente. Os exames foram realizados entre 16 e 20 semanas de gestação e as pacientes foram acompanhadas até o puerpério.Resultados: 15 pacientes tiveram a gestação complicada por PE e 59 mantiveram-se normotensas até o puerpério. Pacientes que subsequentemente desenvolveram PE apresentaram, entre 16 e 20 semanas de gestação, maiores valores no índice de pulsatilidade das artérias uterinas (p<0,001), mas a análise da DFM não apresentoudiferença em relação às pacientes que se mantiveram normotensas. Conclusão:os dados observados sugerem que a deficiência no processo de placentação precede cronologicamente as manifestações clínicas de PE, o que não ocorre com a disfunção endotelial.
Introduction: the pathophysiology of preeclampsia (PE) is based on a deficiency in the process of placentation associated with systemic maternal endothelial dysfunction. The investigation on the occurrence of these phenomena before the onset of PE clinical manifestations can become a new diagnostic method for its prediction. Objectives:to compare the process of placentation and endothelial function in pregnant women athigh-risk for PE development, correlating these findings with its further development. Patients and methods: 74 pregnant women underwent flow-mediated dilation (DFM) of the brachial artery and Doppler flowmetry of uterine arteries to assess endothelial function and placentation process, respectively. The examinations were performedbetween 16 and 20 weeks of gestation and patients were followed until the postpartum period. Results: 15 patients had pregnancies complicated by PE and 59 remained normotensive until the postpartum period. Patients who subsequently developed PE presented high values of pulsatility index in uterine arteries (p <0.001), between 16 and 20 weeks gestation, however, the analysis of DFM did not show difference compared to patients who remained normotensive.Conclusion: The observed data suggest that deficiency in the placentation process chronologically precedes the clinical manifestations of PE, which does not occurwith endothelial dysfunction.
RESUMEN
A ocorrência de sintomas neurológicos agudos em gestantes ou puérperas não é incomum. Podem ser causados tanto pela exacerbação de uma doença neurológica pré-existentes quanto por doenças relacionadas com a própria gravidez. O diagnóstico preciso é essencial para o tratamento adequado. Sendo assim, é recomentado acompanhamento multidisciplinar antes, durante e após a gravidez. O objetivo do presente estudo é realizar uma revisão da literatura sobre as principais síndromes neurológicas durante a gravidez, descrevê-las e elucidar como é feito o diagnóstico adequado. Para isso, foi realizada uma busca de artigos na base de dados do Medline, via Pubmed, sendo selecionados artigos publicados nos últimos 10 anos, nas línguas inglesa ou portuguesa. Desse modo, o presente estudo demonstra a importância de saber reconhecer e tratar adequadamente cada uma dessas síndromes, bem como de um acompanhamento em centro de referência, uma vez que as síndromes neurológicas estão relacionadas com morbidade e mortalidade materna.(AU)
The occurrence of acute neurological symptoms in pregnant women and during puerperium is not uncommon. This symptoms can be caused both by the exacerbation of a preexisting neurological disease and illnesses related to the pregnancy itself. The accurate diagnosis is essential for proper treatment. Therefore, it is recommended that a multidisciplinary monitoring before, during and after pregnancy. The aim of this study is to conduct a review of the literature on the main neurological syndromes during pregnancy, describe them and elucidate how is made the proper diagnosis. For this, a search for articles on Medline database, via Pubmed was performed, being selected articles published in the last 10 years, in English or Portuguese languages. Thus, the present study demonstrates the importance of knowing recognize and properly handle each of these syndromes, as well as a follow-up in tertiary centers, once the neurologicalsyndromes are related to maternal morbidity and mortality.(AU)

A adaptação fisiológica do organismo materno à gestação inclui principalmente a vasodilatação sistêmica e o aumento do volume sanguíneo para um adequado fluxo sanguíneo placentário. Alterações nesse processo causam o desenvolvimento de doenças potencialmente graves, como a pré-eclâmpsia e o diabetes gestacional. Apesar de serem diferentes entre si, vários estudos vêm apontando uma alteração em comum, que é a base do desenvolvimento das duas doenças: a lesão endotelial. Há diferenças na forma como essa lesão é desencadeada, mas os produtos liberados a partir dessa alteração promovem vasoconstrição sanguínea e levam à piora da lesão endotelial e do quadro clínico, atuando assim como uma reação em cadeia. São mostrados nesse estudo as alterações sofridas no endotélio, o ponto de convergência na fisiopatologia da pré-eclâmpsia e do diabetes gestacional, e as várias formas de avaliação clínica dessa lesão, que podem ser usados para detecção precoce dessas doenças e melhor manejo do seu desenvolvimento.(AU)
The physiological adaptation of the maternal organism to pregnancy mainly includes systemic vasodilation and increased blood volume allowing a suitable placental blood flow. Changes in this process may lead to the development of potentially serious diseases, such as pre-eclampsia and gestational diabetes. Although they are different from each other, a variety of studies points out a common event which is the base of development of two diseases: the endothelial injury. There are differences in how this injury is unleashed, but the products released from this lesion promote vasoconstriction and worse of clinical manifestations, acting just like a chain reaction. This study aims to discuss the changes suffered in the endothelium, the most likely point of convergence in the pathophysiology of pre-eclampsia and gestational diabetes, as well as the various forms of clinical assessment of endothelial dysfunction, potential markers of the clinical onset of these gestational diseases.(AU)

Postpartum depression is one of the most prevalent psychopathologies. Its prevalence is estimated to be between 10% and 15%. Despite its multifactorial etiology, it is known that genetics play an important role in the genesis of this disorder. This paper reviews epidemiological evidence supporting the role of genetics in postpartum depression (PPD). The main objectives of this review are to determine which genes and polymorphisms are associated with PPD and discuss how this association may occur. In addition, this paper explores whether these genes are somehow related to or even the same as those linked to Major Depression (MD). To identify gaps in the current knowledge that require investigation, a systematic review was conducted in the electronic databases PubMed, LILACS and SciELO using the index terms "postpartum depression" and "genetics". Literature searches for articles in peer-reviewed journals were made until April 2014. PPD was indexed 56 times with genetics. The inclusion criteria were articles in Portuguese, Spanish or English that were available by institutional means or sent by authors upon request; this search resulted in 20 papers. Genes and polymorphisms traditionally related to MD, which are those involved in the serotonin, catecholamine, brain-derived neurotrophic factor and tryptophan metabolism, have been the most studied, and some have been related to PPD. The results are conflicting and some depend on epigenetics, which makes the data incipient. Further studies are required to determine the genes that are involved in PPD and establish the nature of the relationship between these genes and PPD.
RESUMEN
Background: central nervous system (CNS) hyperperfusion is one of the events that constitute the pathophysiological basis for the clinical manifestations and complications of pre-eclampsia (PE). Detecting the increased flow in the CNS through Doppler flowmetry of the ophthalmic artery might precede the clinical onset of PE and could be used as a marker for subsequent development of PE. Objective: to evaluate the ophthalmic artery resistive index (OARI) values in the second trimester of pregnancy for prediction of the clinical manifestations of PE. Objective: to evaluate the ophthalmic artery resistive index (OARI) values in the second trimester of pregnancy for prediction of the clinical manifestations of PE. Methods: a total of 73 patients with risk factors for the development of PE were selected from the prenatal service at the HC-UFMG. They were submitted to ophthalmic artery Doppler flowmetry between 24 and 28 weeks of pregnancy and monitored until the end of the pregnancy to verify the occurrence of PE. ROC curves were created to determine the predictive characteristics of the OARI. Results: fourteen of the patients selected developed PE and 59 remained normotensive until the postpartum period. Patients with subsequent development of PE presented OARI values lower than patients that remained normotensive (0.682±0.028 X 0.700±0.029, p=0.044). Considering the development of PE as an outcome, the area under the OARI curve was 0.694 (CI 0.543 to 0.845), with no points obtaining good values of sensitivity or specificity. Conclusion: Doppler flowmetry of ophthalmic arteries between 24 and 28 weeks of pregnancy did not present itself as a good exam for predicting PE. .
Introdução: a hiperperfusão do sistema nervoso central (SNC) é um dos eventos que constitui substrato fisiopatológico para as manifestações clínicas e complicações da pré-eclâmpsia (PE). O fluxo aumentado no SNC, detectado por meio da dopplerfluxometria de artérias oftálmicas, poderia anteceder as manifestações clínicas da PE e, consequentemente, ser utilizado como marcador de subsequente desenvolvimento de PE. Objectivo: avaliar os valores do índice de resistência das artérias oftálmicas (Irao) no segundo trimestre gestacional para a predição das manifestações clínicas da PE. Métodos: pacientes com fatores de risco para desenvolvimento de PE foram selecionadas no serviço de pré-natal do Hospital das Clínicas da Universidade Federal de Minas Gerais (HC-UFMG). Elas foram submetidas à dopplerfluxometria de artérias oftálmicas entre 24 e 28 semanas de gestação e acompanhadas até o final da gestação para averiguar a ocorrência de PE. Curvas ROC foram criadas para determinar as características preditivas do Irao. Resultados: das pacientes selecionadas, 14 desenvolveram PE e 59 mantiveram-se normotensas até o puerpério. Pacientes com subsequente desenvolvimento de PE apresentaram valores de Irao menores do que pacientes que se mantiveram normotensas (0,682±0,028 vs. 0,700±0,029, p=0,044). Ao considerar o desenvolvimento de PE como desfecho, a área sobre a curva do Irao foi de 0,694 (IC 0,543-0,845), sem pontos com bons valores de sensibilidade ou especificidade. Conclusão: a dopplerfluxometria de artérias oftálmicas entre 24 e 28 semanas de gestação não se demonstrou um bom exame para a predição de PE. .

O Diabetes Mellitus Gestacional (DMG) é definido como intolerância a carboidratos com início ou diagnóstico durante a gestação. Em gestantes com DMG, é importante o controle da glicemia a fim de reduzir ou evitar efeitos adversos como abortamento, malformações congênitas e crescimento fetal anormal. Tradicionalmente, a insulina é usada como medicamento de escolha, segura para mãe e feto e eficaz no sentido de controlar os valores glicêmicos maternos. A Metformina é um hipoglicemiante oral que age aumentando a sensibilidade dos tecidos à insulinaNos estudos disponíveis, quando comparada à insulina, a Metformina mostra uma menor taxa de hipoglicemia neonatal grave, porém, não foi observada diferença significativa em relação a outros resultados perinatais, tal como prematuridade. A gliburida é um hipoglicemiante que aumenta a secreção de insulina pelas células beta pancreáticas. É uma droga bem tolerada e apresenta baixa taxa de hipoglicemia materna, em torno de 1,5% das pacientes. A gliburida mostrou eficácia semelhante à insulina em diversos estudos no controle glicemico. Mais estudos clínicos randomizados se fazem necessários no momento atual de discussão sobre os reais benefícios e riscos dessas drogas, a fim de definir seu papel efetivo no tratamento do DMG, consolidando ou não, sua recomendação e seu uso amplo.(AU)
Gestational Diabetes (GMD) is defined as carbohydrate intolerance with onset or first recognition during pregnancy. In pregnants, with GMD the glucose control is important to minimize the risk of miscarriage, fetal congenital malformations and macrossomia. Traditionally, insulin is used, since it does not cross the placenta, being considered safe for the woman and the fetus. Metformin is a hypoglycemic agent that acts as an insulin sensitizer, inhibits gluconeogenesis, suppresses hepatic glucose output and increase intestinal glucose absorption. It crosses the placenta, but it is not considered teratogenic. When compared with insulin, Metformin shows a lower incidence of severe neonatal hypoglycemia, with no difference in rates of other perinatal complications, as prematurity. Glyburide is a hypoglycemic that increases insulin secretion by pancreatic beta cells and sensitivity in peripheral tissues and reducing hepatic clearance of insulin. It shows similar efficacy of insulin on glucose control with a lower rate of maternal hypoglycemia, around 1.5% of patients. The glyburide showed similar efficacy to insulin in several studies in glycemic control. It is still suggested that the use of agent hypoglycemic on DMG can induce a lower maternal weight gain and more treatment adherence. More randomized clinical studies are required to ensure the real benefits and risks of these drugs, in order to define its use on GMD treatment.(AU)
