ABSTRACT
OBJECTIVE: Recently, it has been discussed whether or not mosaic embryo transfers should be performed since they might result in viable pregnancies, although they often end up being discarded. We report a case of successful pregnancy, after a mosaic embryo transfer from an in vitro matured egg and frozen PESA sperm. CASE DESCRIPTION: Tests performed on a female aged 40 years and a male aged 37 years seeking fertility treatment found she had an adequate ovarian reserve and patent fallopian tubes. He had a history of cryptorchidism and inguinal hernia repair. The spermogram showed azoospermia, and testicular ultrasound showed an atrophic left testicle and a normal right testis. The vas deferens was palpated during physical examination. Intracytoplasmic sperm injection with percutaneous epididymal sperm aspiration (PESA) was indicated. Two cycles of IVF after controlled ovarian stimulation with follitropin delta was performed. In the first cycle, seven mature eggs were inseminated, two fertilized normally, resulting in one blastocyst biopsied and analyzed by NGS with complex aneuploid results. In the second cycle, frozen sperm from PESA was used. Three eggs were inseminated on the day of the procedure (resulting in 2 blastocysts), and three in vitro matured eggs were inseminated after 24 hours (resulting in 1 blastocyst). NGS analysis showed two complex aneuploid embryos and one 40% low-level trisomy 20 aneuploid mosaicism (+20) for the post 24-hour embryo. A mosaic embryo transfer was performed, resulting in clinical pregnancy and birth of a healthy baby girl with a normal blood karyotype. DISCUSSION: Mosaic embryo transfer is a topic for discussion. Certain levels of mosaicism do not seem to pose risks to the development of the fetus.

OBJECTIVE: To evaluate clinical and laboratory outcomes of oocyte donation cycles and compare the results from donors and recipients. METHODS: A retrospective cohort study was conducted at a reproductive medicine center. A 586 first fresh oocyte donation cycles, performed from 01/2002 to 12/2017 were included. The outcomes of 290 cycles from donors and 296 from recipients, resulting in 473 fresh embryo transfers, were analyzed. The oocyte division was equally made, whereas, at an odd amount, the donor always had a preference. The data were collected from an electronic database, and analyzed using Chi-square test, Fisher's exact test, Mann-Whitney U-test or Student t-test depending on the data distribution, and multivariate logistic regression, considering p<0.05. RESULTS: The main results comparing donor and recipient, were, respectively: fertilization rate (72.0±21.4 vs. 74.6±24.2, p<0.001), implantation rate (46.2% vs. 48.5%, p=0.67); clinical pregnancy rate (41.9% vs. 37.7%, p=0.39), live birth rates by transfer (33.3 vs. 37.7, p=0.54). CONCLUSIONS: Oocyte donation is often the way donors can access in vitro fertilization, and for recipients seems to be a good option for pregnancy. Demographic and clinical characteristics have a secondary role in oocyte donors under 35 years and patient without comorbidities under 50 years and were not associated with pregnancy outcomes, emphasizing the power of oocyte quality on the success of intracytoplasmic sperm injection treatment. An oocyte-sharing program that offers good and comparable results is fair and worth being encouraged.

OBJECTIVE: Oocyte cryopreservation enables the storage of genetic material, especially in situations where the ovarian function is compromised, also for women desiring to postpone maternity. Before 2012, oocyte cryopreservation was still experimental, and the success of the procedure was uncertain; however, it was the only possibility that women had for fertility preservation. Thus, we aim to report a case of a birth after 13 years of elective oocyte cryopreservation. CASE DESCRIPTION: At 49 years of age, the patient returned to our reproductive center with the desire to get pregnant, using oocytes that had been frozen for 13 years. The endometrium was prepared, and the oocytes were thawed using the slow procedure method. Four of the six oocytes thawed survived (66%) and were inseminated; three fertilized and started their development. The transfer of two embryos on the third day of development was performed. Clinical pregnancy was confirmed via ultrasound and came to term with the birth of a healthy boy. DISCUSSION: Although the vitrification procedure has shown to be a better cryopreservation technique when compared to slow freezing, the latter represented an important role when patients wanted to cryopreserve oocytes in the early 2000s. Even many years later, this technique reveals its efficacy, preserving the viability and quality of oocytes stored in nitrogen tanks. After a literature review, this case seems to be the largest interval between oocyte cryopreservation and its use, with achieved pregnancy, in Brazil.

BACKGROUND: The aim of this study was to evaluate the influence of the body mass index (BMI) on laboratory, clinical outcomes and treatment costs of assisted reproduction, as there are still controversial and inconclusive studies on this subject. METHODS: This research was retrospective cohort study, including women undergoing assisted reproduction in a Reproductive Medicine Center between 2013 and 2020. The participants were divided into groups according to BMI (kg/m2): Group 1 < 25; Group 2, 25-29.9 and Group 3, ≥ 30. A total of 1753 in vitro fertilization (IVF) fresh embryo transfer (ET) cycles were included for assisted reproduction outcomes analysis and 1869 IVF-ET plus frozen embryo transfer (FET) for cumulative pregnancy analysis. RESULTS: As higher the BMI, higher was the proportion of canceled IVF cycles (G1 (6.9%) vs. G2 (7.8%) vs. G3 (10.4%), p = 0.002) and gonadotropin's total dose (IU) and treatment costs (G1 (1685 ± 595, U$ 683,02) vs. G2 (1779 ± 610, U$ 721,13) vs. G3 (1805 ± 563, U$ 764,09), p = 0.001). A greater number of mature oocytes was observed in G1 and G2 (6 [6.4-7.0] vs. 6 [5.6-6.6] vs. 4 [4.6-6.7], p = 0.011), which was not found in oocyte maturity rate (p = 0.877). A significant linear tendency (p = 0.042) was found in cumulative pregnancy rates, pointing to worse clinical outcomes in overweight and obese patients. CONCLUSION: These findings highlight the importance of considering the higher treatment costs for these patients, beyond all the well-known risks regarding weight excess, fertility, and pregnancy, before starting IVF treatments.

BACKGROUND: In spontaneous pregnancies, maternal weight and gestational diabetes are independent risk factors for macrosomia and large-for-gestational-age newborns. Furthermore, maternal body mass index (BMI) of ≥25 kg/m2 is associated with worse neonatal vitality, classified as an Apgar score of < 7 at the fifth minute of life. However, few studies have evaluated the influence of BMI on perinatal outcomes in pregnancies resulting from assisted reproduction. Therefore, this study aimed to analyze whether the perinatal outcomes of assisted reproduction are influenced by BMI. METHODS: This was a retrospective cohort study performed at a reproductive medicine center. Patients undergoing assisted reproduction (2013-2020) were divided into three groups according to their BMI (kg/m2): group 1, < 25; group 2, 25-29.9, and group 3, ≥30. In total, 1753 in vitro fertilization embryo transfer cycles were analyzed. Data were expressed as mean ± standard deviation or frequency (%). The analysis of variance and chi-square test were performed for comparison. To determine the participants and number of cycles for these analyses, generalized estimating equations were used, considering p < 0.05. RESULTS: In groups 1, 2, and 3, the rates of live birth were 33.5, 32.3, and 29.9% (p = 0.668); preeclampsia were 2.9, 6.1, and 6.3% (p = 0.268); small-for-gestational-age newborns were 23, 23.2, and 21.7% (p = 0.965); macrosomia were 1.9, 0.9, and 2.7% (p = 0.708); Apgar score > 7 at the fifth minute were 97.6, 98.2, and 100% (p = 0.616); and preterm birth were 29.6, 30.1, and 35.1% (p = 0.970), respectively. CONCLUSIONS: In conclusion, although the three groups had similar perinatal outcomes in this study, the study population was too small for conclusive results. The higher the BMI, the lower the chances of clinically relevant LBR and the higher the chances of premature labor and preeclampsia.

OBJECTIVE: Outcome data for oocyte vitrification for fertility preservation are still scarce despite the scientific and technological advances. Studies suggest that patients with cancer have worse outcomes regarding mature vitrified oocytes when compared to healthy patients. Thus, the objective of this study was to evaluate and compare the oocyte vitrification response in patients undergoing elective and oncofertility preservation. METHODS: The ovarian stimulation response was verified by a cross-sectional and observational study, analyzing data from 367 patients between 2009 and 2018, which were divided into elective group (EG; n=327) and oncofertility group (OFG; n=40). The number of follicles, oocytes, mature oocytes, and duration of the cycle was evaluated, which were compared with clinical and ovarian stimulus data between groups. RESULTS: A significant difference in women's age (31.3±5.8 vs. 37.0±2.9 years; p<0.01) and basal values of Follicle Stimulating Hormone (FSH), (4.0 [3.3 - 6.2] vs. 9.0 [5.4 - 9.9] mIU/mL; p<0.01) were observed. When adjusting data for age, FSH and Gonadotropin-releasing Hormone protocols, no significant difference in the number of vitrified mature oocytes between the two groups were observed (6.0 [3.0-11.0] vs. 7.0 [3.0-12.0]; p=0.11). CONCLUSIONS: Thus, patients undergoing elective and oncofertility preservation seem to respond similarly to controlled ovarian stimulation for fertility preservation. Breast cancer was the most frequent in the OFG (67%).

OBJECTIVE: Ectopic pregnancy is a well-known complication following in vitro fertilization with embryo transfer; studies have questioned, however, whether there are risk factors that could be identified before the procedure. The objective of this study was to investigate the possible risk factors involved in ectopic pregnancy following in vitro fertilization. METHODS: Retrospective case-control study performed at an assisted reproduction clinic in Brazil. To select the control group, we used a 1:4 ratio. The study included 499 patients submitted to in vitro fertilization with clinical pregnancy. We collected the data from electronic records, between 2000-2019 and divided into: Group 1, ectopic pregnancy (n=90) and Group 2, intrauterine pregnancies (n=409). RESULTS: When comparing groups, the results observed were: Tubal factor infertility (35.6% vs. 21.1%, p=.005) (OR 2.0 [1.2-3.4], p=.004); Previous miscarriage history (15.1% vs. 7.1%, p<.05) (OR 2.0 [1.02-4.29], p=.044); Number of cleavage-stage embryo transfers (69.2% vs. 54.0 p=.028) (OR 1.9 [1.08-3.33], p=.025); Two or more embryos transferred (OR 2.5 [1.12-5.70], p=.025), all associated with greater ectopic pregnancy risk. Oocyte recipient patients were excluded from this analysis, but when included a difference was found when comparing the groups (9.4% (10/106) vs. 3.0% (13/434), p=.007), (OR 3.3 [1.41-7.98] p=.005); this result should be interpreted with caution because of the sample size. CONCLUSIONS: In high-risk patients, a single blastocyst transfer seems to be a reasonable approach to decrease the ectopic pregnancy risk.

With the growing understanding of in vitro fertilization and reproductive technology, the magnitude of studies related to embryonic evolution has also increased. The optimization of embryo selection is crucial to minimize the risk of multiple pregnancies and to guarantee successful implantation and pregnancy. On the second day of culture, the four-cell embryo can be shaped into different arrangements, such as tetrahedral and planar. Previous studies have shown that mammalian embryos have a tetrahedral shape and that any deviation from this ideal configuration can negatively affect blastocyst development. A few studies have also found that planar embryos would be linked to negative predictors of success for reaching the blastocyst stage and its good quality. Therefore, it seems that tetrahedral should be preferred over planar-shaped embryos for embryonic transfers, but there is still little understanding and evidence about this subject. Thus, the objective of the present paper was to review the available literature on study tendencies to compare tetrahedral and planar-shaped embryos considering their effect on implantation and pregnancy results.

A síndrome de Turner decorre de uma anomalia dos cromossomos sexuais, afetando cerca de 1:2.500 nascidos vivos. A síndrome caracteriza-se principalmente por atraso do e denvolvimento dos caracteres sexuais e/ou amenorreia e baixa estatura. Entretanto, uma diversidade de estigmas também pode estar presente. O diagnóstico pode ser realizado com base nos estigmas da síndrome associados a um quadro de hipogonadismo hipergonadotrófico e confirmado por meio do cariótipo sendo esse classicamente 45,X (monossomia do cromossomo X). Entretanto, os mosaicos (45,X/46,XY ou 45,X/46,XX) podem representar 34% a 75% dos casos, dependendo do método de análise utilizado. Trata-se de uma condição rara correspondendo a 5% das disgenesia gonadais e apresenta um amplo espectro fenotípico. A importância da identificação de mosaicos, especialmente a presença do cromossomo Y, reside no manejo adequado da gônada disgenética para a prevenção da ocorrência de tumor gonadal, principalmente o gonadoblastoma, com considerável potencial maligno.(AU)
Turner's syndrome results from a sex chromosomes anomaly, affecting about 1:2,500 live births. The syndrome is characterized mainly by delayed development of sexual characteristics and/or amenorrhea and short stature. However, a variety of stigmas may also be presented. The diagnosis can be made based on the stigmas of the syndrome associated with a hypergonadotrophic hypogonadism and confirmed by the karyotype this being classically 45, X (monosomy of the X chromosome). However, mosaics (45,X/46,XY or 45,X/46, XX) may represent 34% to 75% of cases depending on the method of analysis used. It is a rare condition, corresponding to 5% of gonadal dysgenesis and presents a broad phenotypic spectrum. The importance of mosaic identification, especially the presence of the Y chromosome, lies in the proper management of the dysgenetic gonad for the prevention of the occurrence of gonadal tumor, especially gonadoblastoma, with considerable malignant potential.(AU)

The pathogenesis of endometriosis is not clear; however, microRNAs (miRNAs/miRs) are involved in the pathogenesis. miRNAs are short noncoding RNAs involved in post-transcriptional regulation of gene expression by silencing the expression of target genes. The expression of miR-135a/b is associated with endometrial receptivity and implantation; the expression is also associated with the expression of certain genes, including homeobox protein Hox-A10 (HOXA-10). The present study investigated the expression of miR-135a/b in eutopic and ectopic endometrium tissues throughout the different phases of the menstrual cycle. Samples of ectopic endometriosis lesions and eutopic endometrium tissue from 23 patients who underwent laparoscopic surgery were obtained and analyzed. miRNA was extracted and the expression levels of miR-135a/b were determined by reverse transcription quantitative polymerase chain reaction assays using U6 as a housekeeping control. The expression levels of miR-135a and miR-135b in endometriosis lesions were decreased compared with the levels in endometrium tissue. However, miR-135a/b expression levels were increased in the secretory phase compared with the proliferative phase in endometriosis lesions. The increased expression of miR-135a/b during the secretory phase compared with the proliferative phase suggested that these genes serve a determinant role in the homeostasis of reproductive tissue. Therefore, the expression of genes may affect endometrial functioning, impairing embryo implantation.
ABSTRACT
Bilateral ectopic pregnancy is a rare clinical condition with an estimated prevalence of 1/200 000 in spontaneous pregnancies. Studies have found that In Vitro Fertilization (IVF) is related to ectopic pregnancy independently, but the incidence of tubal disease in the donor egg recipient population is thought to be significantly lower than in the standard IVF population. We report the case of a patient participating in the egg-sharing program, who was diagnosed with ovarian ectopic pregnancy, treated with surgery. After one week, she was diagnosed with tubal ectopic pregnancy in the contralateral tube. The clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operatory inspection of both side fallopian tubes in any ectopic pregnancy case. Routine ultrasound after ectopic pregnancy treatment may be reasonable, especially in high risk patients.

OBJECTIVES: Eclampsia results in high morbidity and mortality, so it is important to identify clinical and laboratorial aspects that may be useful as potential markers to differentiate women at higher risk. Thus, we aim to identify, among women with preeclampsia, aspects that may increase the risk to develop eclampsia. STUDY DESIGN: Retrospective cohort study. The records of patients delivered at Hospital São Lucas/PUCRS were reviewed retrospectively; 733 pregnant women with hypertension were analyzed; 329 had preeclampsia, and 45 eclampsia. MAIN OUTCOME MEASURES: Serum uric acid levels and protein excretion in women that develop eclampsia. RESULTS: Patients with eclampsia had higher serum uric acid levels and protein excretion, systolic and diastolic blood pressure; were more likely to have cesarean section and had worst perinatal outcomes. The combination of uric acid above 5.9â¯mg/dL and protein/creatinine ratio over 4.9 had a striking association with eclampsia (pâ¯≤â¯0.001). The occurrence of HELLP syndrome was significantly different between groups, with a higher incidence among women who developed eclampsia (OR 6.5; 95%CI, 3.2-13.2; pâ¯<â¯0.001). CONCLUSION: Our data suggest that the combination of high levels of maternal serum uric acid and proteinuria are strongly associated with the development of eclamptic crises.

AIMS: To evaluate the profile of men with cancer who performed semen cryopreservation prior/during treatment and address the importance of this method for reproductive health. METHODS: This was a transversal and retrospective study which used a database from a Reproductive Medicine Center located in Brazil. A total of 150 male patients who performed semen cryopreservation due to cancer diagnosis, from January 2014 to December 2017, were included. RESULTS: The profile of men seeking fertility preservation prior/during treatment for cancer was young adults, single, childless, with higher education. Oncologists were the ones who reported more patients for semen cryopreservation followed by urologists and hematologists. With regards to tumor diagnosis frequency, testicular was the most diagnosed, followed by Hodgkin's/non-Hodgkin's lymphoma, leukemia, prostate and rectal tumor, along with retroperitoneal tumor. CONCLUSION: Data brought the reflection on the cultural and financial barriers involved for the accomplishment of cryopreservation. Health professionals attending cancer patients should consider the importance of educational and incentive activities to prevent male fertility. Future research on the subject should carried out.
OBJETIVO: Conhecer o perfil dos homens portadores de neoplasias malignas que preservaram sua fertilidade através da técnica de criopreservação de sêmen. METODOLOGIA: A amostra foi composta por 150 pessoas do sexo masculino que realizaram a criopreservação de sêmen no período de janeiro de 2014 a dezembro de 2017. Trata-se de um estudo quantitativo, descritivo, transversal onde foram utilizados dados secundários de um banco de dados de um Centro de Medicina Reprodutiva situado em Porto Alegre, Rio Grande do Sul. RESULTADOS: Os resultados demostraram que o perfil dos homens com câncer que realizaram a criopreservação de sêmen é, em sua maioria, de jovens adultos, solteiros, sem filhos, que estão preocupados em manter sua capacidade reprodutiva após a terapêutica oncológica. CONCLUSÃO: O conhecimento do perfil de pacientes que buscam a preservação dos gametas em casos de doenças oncológicas pode contribuir para o entendimento e possível sugestão de indicação pelos profissionais envolvidos neste tipo de abordagem.

OBJECTIVE: To analyze endocan-1, a biomarker of vascular endothelial related pathologies, and the placental growth factor (PlGF), an angiogenic factor and a placental dysfunction marker in patients with preeclampsia (PE). METHODS: Case-control study conducted at Hospital São Lucas, in the city of Porto Alegre, Brazil. Endocan-1 and PlGF levels were quantified in the maternal plasma using the MagPlexTH-C microsphere system (MAGPIX System, Luminex, Austin, Texas, US) and evaluated through analysis of covariance (ANCOVA) and adjusted by body mass index (BMI), gestational age and maternal age. To estimate the difference between the groups, the mean ratio (MR) and the 95% confidence interval (95%CI) were calculated. The Pearson correlation test was used to establish any association between endocan-1 and PlGF levels. The null hypothesis was rejected when p < 0.05. RESULTS: The group of patients was composed by normotensive (n = 67) patients and patients with PE (n = 50). A negative correlation between endocan-1 and the PlGF was noted in the entire normotensive group (linear correlation coefficient [r] = -0.605; p < 0.001), as well as in the PE group (r = -0.545; p < 0.001). CONCLUSION: Endocan-1 levels are increased in patients with PE, and are inversely correlated with PlGF levels. We suggest that it is important to analyze angiogenic and proinflammatory molecules concomitantly in women with PE to better understand the pathophysiology of the disease. Both molecules are strong candidates for PE biomarkers, and future studies will examine any mechanisms connecting these factors in PE.
OBJETIVO: Analisar o endocan-1, um biomarcador de patologias vasculares endoteliais, e o fator de crescimento placentário (FCPl), um fator angiogênico, marcador de disfunção placentária em pacientes com pré-eclâmpsia (PE). MéTODOS: Estudo de caso-controle realizado no Hospital São Lucas, em Porto Alegre. Os níveis de endocan-1 e FCPl foram quantificados no plasma materno usando o sistema de microesferas MagPlexTH-C (MAGPIX System, Luminex, Austin, Texas, US) e analisados por análise de covariância (ANCOVA) e ajustados por índice de massa corporal (IMC), idade gestacional e idade materna. Para calcular a diferença entre os grupos, utilizou-se a razão das médias (RM) e o intervalo de confiança de 95% (IC95%). O teste de correlação de Pearson foi utilizado para estabelecer a associação entre os níveis de endocan-1 e FCPl. A hipótese nula foi rejeitada quando p < 0,05. RESULTADOS: O grupo de pacientes foi composto por pacientes normotensas (n = 67) e pacientes com PE (n = 50). Uma correlação negativa entre o endocan-1 e o FCPl foi observada em todo o grupo de pacientes normotensas (coeficiente de correlação linear [r] = −0,605; p < 0,001), bem como no grupo com PE (r = −0,545; p < 0,001). CONCLUSãO: Os níveis de endocan-1 estão aumentados em pacientes com PE e inversamente correlacionados com os níveis de FCPl. Sugerimos a importância de analisar moléculas angiogênicas e pró-inflamatórias concomitantemente em mulheres com PE para compreender melhor a fisiopatologia da doença. Ambas as moléculas são fortes candidatos a serem considerados biomarcadores de PE, e trabalhos futuros poderão avaliar quaisquer mecanismos que liguem esses fatores na PE.

Introdução: A fertilidade em mulheres que passaram por tratamento oncológico é um assunto de suma relevância no cenário da medicina atual. É importante que tais pacientes estejam cientes dos possíveis danos à fertilidade que o tratamento para neoplasias pode acarretar; assim como, é essencial que os médicos que lidam com elas saibam expor as opções para a preservação da fertilidade. Métodos: Os artigos foram pesquisados na base de dados PubMed em junho de 2018, utilizando os termos descritores oncologia; câncer, mulheres e fertilidade. Como critérios de inclusão, foram considerados artigos publicados nos últimos 10 anos, no período de junho de 2008 a junho de 2018, artigos que abordassem pesquisas apenas com humanos e aqueles publicados em língua portuguesa, inglesa ou espanhola. Resultados: Na pesquisa inicial, utilizando os termos descritores, foram encontrados 4173 artigos; restringindo aos últimos 10 anos, restaram 2370 artigos; desses, foram selecionados apenas aqueles com pesquisas em seres humanos, restaram 2201 artigos e desses foram selecionados 2063 que estão nos idiomas escolhidos. Elegeu-se 8 artigos para a elaboração desta revisão da literatura. Conclusões: Através deste artigo, foi possível revisar evidências atuais referentes a preservação da fertilidade em mulheres com diagnóstico de câncer. Atualmente há uma ampla variedade de abordagens para manutenção da fertilidade. Diante do desejo de gestar, as escolhas vão depender, principalmente, da idade da paciente, da reserva ovariana e da presença de parceiro.
Introduction: Fertility in women whom went through an oncologic treatment is a subject of utmost importance in the current medical scenario. It is important that these patients are aware of the possible damages to fertility due to oncologic treatments; as well as, it is essential for physicians that deal with cancer patients knowing how to disclose the options available for fertility preservation. Methods: The articles were researched in the PubMed database in June 2018, using descriptor terms as oncology; cancer; women; and fertility. As an inclusion criterion, articles published in the last 10 years were considered, from June 2008 to June 2018, articles whose research was based solely on humans and those published in Portuguese, English and Spanish. Results: In the initial research, using the descriptor terms, 4173 articles were found; restricting those to the last 10 years, 2370 were left; of these, 2201 articles whose research was solely based on humans were selected, of which 2063 are on the selected languages. Eight articles were elected for the formulation of this literature review. Conclusions: Through the elaboration of this article, it was possible to review the current relative evidence to the conservation of fertility in women with the diagnosis of cancer. Nowadays there is a broad range of approaches for the preservation of fertility. Faced on the desire to gestate, choices will vary from the age of the patient and ovarian reserve, to the presence of a male partner.

Para isso, critérios diagnósticos, métodos de investigação e tratamentos, além de uma visão geral sobre suas principais causas foram abordados. Métodos: Os artigos foram pesquisados na base de dados PubMed, em maio de 2018, utilizando os termos descritores miscarriage, recurrent; recurrent miscarriage; recurrent miscarriages; abortion, recurrent; recurrent abortion; recurrent abortions; recurrent pregnancy loss. Como critérios de inclusão, foram considerados artigos publicados nos últimos 5 anos, no período de maio de 2014 a maio de 2018, artigos que abordassem pesquisas apenas com humanos, guidelines e aqueles publicados em língua portuguesa, inglesa ou espanhola. Artigos de revisão foram excluídos da seleção. Resultados: Na pesquisa inicial, utilizando os termos descritores, foram encontrados 4492 artigos; restringindo aos últimos 5 anos, restaram 1429 artigos; desses, foram selecionados apenas aqueles com pesquisas em seres humanos, restaram 1004 artigos e desses selecionamos 962 que estão nos idiomas escolhidos. Os artigos de revisão foram excluídos da seleção. Vinte artigos foram incluídos para a elaboração desta revisão da literatura. Conclusões: Através deste artigo foi possível revisar evidências atuais referentes a diagnóstico e a manejo clínico nos casos de abortamento de repetição. Além de proporcionar conhecimento e orientação a estudantes e profissionais, o artigo levanta questões que ainda não estão bem estabelecidas na prática clínica e que ainda necessitam de maiores estudos.
Objective: The recurrent pregnancy loss affects approximately 1% to 2% of couples. Due to its importance, the present revision aims to approach the best clinical management. To do that, diagnosis criteria, research and treatments methods, as well as the general vision of the main causes, were discussed. Methods: The articles were searched in the PUBmed database, in May 2018, using keywords: miscarriage, recurrent; recurrent miscarriage; recurrent miscarriages; abortion, recurrent; recurrent abortion; recurrent abortions; recurrent pregnancy loss. As inclusion criteria, articles published in the past 5 years were chosen, from May 2014 to May 2018, articles that deal with researches in humans, guidelines and publications in portuguese, spanish or english. Revision articles were excluded. Results: In the initial search, using the terms descriptors, we found 4492 articles; restricting to the last 5 years, 1429 papers were found; selecting only those in humans, there were 1004 articles remaining and of those 962 selected in the chosen languages. Review articles were excluded from the selection. Twenty articles were selected for this review. Conclusions: Through this article it was possible to review current evidence regarding diagnosis and clinical management in recurrent pregnancy loss. In addition to provide knowledge and guidance to students and professionals, the article raises questions that are not well established in clinical practice yet and that still require further study.

OBJECTIVES: To describe a case of Posterior Reversible Encephalopathy Syndrome diagnosed in pregnant women with late-eclampsia, as well as its clinical management. CASE DESCRIPTION: A 34 years old patient in her third pregnancy had started with high blood pressure levels during labor; after eleven days postpartum, she presented a decreased right visual acuity; subsequently one episode of seizure followed by partial loss of vision in the right eye. After conducting tests and ruled out stroke, the patient was diagnosed as Posterior Reversible Encephalopathy Syndrome (PRES). Established the clinical management of seizures and hypertensive crisis, there was complete remission of symptoms and reversal of the initial clinical picture. CONCLUSION: Once properly diagnosed and treated, the Posterior Reversible Encephalopathy Syndrome can present satisfactory progress, especially when associated with an acutely triggered factor, as eclampsia.

Resumo Objetivos: Descrever um caso de Síndrome da Encefalopatia Reversível Posterior em gestante diagnosticada com eclâmpsia tardia, bem como seu manejo clínico. Descrição do caso: Paciente feminina, 34 anos, em sua terceira gestação, iniciou com aumento dos níveis tensionais durante o trabalho de parto e, após onze dias de puerpério, apresentou quadro de diminuição da acuidade visual à direita, seguida de crise convulsiva e subsequente perda parcial da visão do olho direito. Após a realização de exames de imagem e descartada a possibilidade de acidente vascular encefálico, a paciente foi diagnosticada com Síndrome da Encefalopatia Reversível Posterior (PRES). Instituído o manejo clínico das crises convulsivas e hipertensivas, houve remissão completa dos sintomas e reversão do quadro clínico inicial. Conclusões: Uma vez adequadamente diagnosticada e tratada, a Síndrome da Encefalopatia Reversível Posterior pode apresentar evolução satisfatória, especialmente quando associada a um fator desencadeado agudamente, como a eclâmpsia.

BACKGROUND: Imbalance in hemostatic mechanisms can occur during pregnancy with a tendency for hypercoagulability and increased thrombosis risk. Pregnant women with hypertensive disorder, especially preeclampsia, show alterations in platelet indexes. Immature platelet fraction (IPF) has been suggested as a sensitive index for monitoring changes in platelet production and destruction. OBJECTIVES: To evaluate the IPF in patients diagnosed with a gestational hypertensive disorder (GHD). PATIENTS AND METHODS: A cross-sectional study was conducted at an University Hospital to estimate maternal blood IPF index in 99 pregnant women, divided into three groups: normotensive pregnancy (NP), preeclampsia syndrome (PES), and non-proteinuric hypertensive pregnancy (nPHP). Following ethical approval and written informed consent, samples were collected from 33 NP, 34 PES, and 32 nPHP women. Platelet indexes were measured by fluorescent flow cytometry. RESULTS: IPF and mean platelet volume (MPV) counts in GHD were significantly higher than in NP (IPF: 3.8, 2.4-5.1%; 8.6, 5.8-10.6%; 7.3, 4.2-10.2%; p < 0.001 and MPV: 10.6 ± 0.9 fL; 12.1 ± 1.0 fL; 11.6 ± 1.0 fL; p < 0.001 for NP, PES, and nPHP, respectively). No difference was detected between PES and nPHP groups. The distribution of patients with an IPF above 6.1%for NP, PES, and nPHP was 9%, 65%, and 43.8%, respectively (p < 0.001). IPF as a test to differentiate GHD from the controls achieved an area under the curve of 0.83 on a receiver operating characteristics curve. CONCLUSION: A distinct profile in platelet indexes was detected in hypertensive pregnancies. It suggests that these markers could be used in daily routine as an additional tool in the management of pregnant women.
