RESUMO
OBJECTIVE: The aim of the study was to evaluate potential changes in the clinical, diagnostic, and therapeutic parameters of complete hydatidiform mole in the last 25 years in Brazil. METHODS: A retrospective cohort study was conducted involving the analysis of 2163 medical records of patients diagnosed with complete hydatidiform mole who received treatment at the Rio de Janeiro Reference Center for Gestational Trophoblastic Disease between January 1988 and December 2012. For the statistical analysis of the natural history of the patients with complete molar pregnancies, time series were evaluated using the Cox-Stuart test and adjusted by linear regression models. RESULTS: A downward linear temporal trend was observed for gestational age of complete hydatidiform mole at diagnosis, which is also reflected in the reduced occurrence of vaginal bleeding, hyperemesis and pre-eclampsia. We also observed an increase in the use of uterine vacuum aspiration to treat molar pregnancy. Although the duration of postmolar follow-up was found to decline, this was not accompanied by any alteration in the time to remission of the disease or its progression to gestational trophoblastic neoplasia. CONCLUSIONS: Early diagnosis of complete hydatidiform mole has altered the natural history of molar pregnancy, especially with a reduction in classical clinical symptoms. However, early diagnosis has not resulted in a reduction in the development of gestational trophoblastic neoplasia, a dilemma that still challenges professionals working with gestational trophoblastic disease.

OBJECTIVE: To relate preevacuation platelet count and leukogram findings, especially neutrophil/lymphocyte ratios (NLR) and platelet/lymphocyte ratios with the occurrence of gestational trophoblastic neoplasia (GTN) after complete hydatidiform mole (CHM) among Brazilian women. METHODS: Retrospective cohort study of patients with CHM followed at Rio de Janeiro Federal University, from January/2015-December/2020. Before molar evacuation, all patients underwent a medical evaluation, complete blood count and hCG measurement, in addition to other routine preoperative tests. The primary outcome was the occurrence of postmolar GTN. RESULTS: From 827 cases of CHM treated initially at the Reference Center, 696 (84.15%) had spontaneous remission and 131 (15.85%) developed postmolar GTN. Using optimal cut-offs from receiver operating characteristic curves and multivariable logistic regression adjusted for the possible confounding variables of age and preevacuation hCG level (already known to be associated with the development of GTN) we found that ≥2 medical complications at presentation (aOR: 1.96, CI 95%: 1.29-2.98, p<0.001) and preevacuation hCG ≥100,000 IU/L (aOR: 2.16, CI 95%: 1.32-3.52, p<0.001) were significantly associated with postmolar GTN after CHM. However, no blood count profile findings were able to predict progression from CHM to GTN. CONCLUSION: Although blood count is a widely available test, being a low-cost test and mandatory before molar evacuation, and prognostic for outcome in other neoplasms, its findings were not able to predict the occurrence of GTN after CHM. In contrast, the occurrence of medical complications at presentation and higher preevacuation hCG levels were significantly associated with postmolar GTN and may be useful to guide individualized clinical decisions in post-molar follow-up and treatment of these patients.

The PIPA Project is a prospective birth cohort study based in Rio de Janeiro, Brazil, whose pilot study was carried out between October 2017 and August 2018. Arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) concentrations were determined in maternal (n = 49) and umbilical cord blood (n = 46). The Denver Developmental Screening Test II (DDST-II) was applied in 50 six-month-old infants. Metals were detected in 100% of the mother and newborn samples above the limits of detection. Maternal blood lead concentrations were higher in premature newborns (GM: 5.72 µg/dL; p = 0.05). One-third of the infants (n = 17-35.4%) exhibited at least one fail in the neurodevelopment evaluation (fail group). Maternal blood arsenic concentrations were significantly (p = 0.03) higher in the "fail group" (GM: 11.85 µg/L) compared to infants who did not fail (not fail group) (GM: 8.47 µg/L). Maternal and umbilical cord blood arsenic concentrations were higher in all Denver Test's domains in the "fail group", albeit non-statistically significant, showing a tendency for the gross motor domain and maternal blood (p = 0.07). These findings indicate the need to further investigate the toxic effects of prenatal exposure to metals on infant neurodevelopment.

Group B Streptococcus (GBS) is a leading cause of neonatal infections. The genitourinary and gastrointestinal tract of pregnant women are the main source of transmission to newborns. This work investigated the prevalence and characterized GBS from pregnant women in Rio de Janeiro, Brazil, comparing the periods before (January 2019 to March 2020; 521) and during (May 2020 to March 2021; 285) the COVID-19 pandemic. GBS was detected in 10.8% of anovaginal samples. Considering scenarios before and during the pandemic, GBS colonization rate significantly decreased (13.8% vs. 5.3%; p = 0.0001). No clinical and sociodemographic aspect was associated with GBS carriage (p > 0.05). A total of 80%, 13.8% and 4.6% GBS strains were non-susceptible to tetracycline, erythromycin and clindamycin, respectively. Serotype Ia was the most frequent (47.7%), followed by V (23.1%), II (18.4%), III (7.7%) and Ib (3.1%). An increasing trend of serotypes Ib and V, as well as of antimicrobial resistance rates, and a decreasing trend of serotypes II and III, were observed after the pandemic onset, albeit not statistically significant (p > 0.05). The reduction in GBS colonization rates and alterations in GBS serotypes and resistance profiles during the pandemic were not due to changes in the sociodemographic profile of the population. Considering that control and preventive measures related to the COVID-19 pandemic onset have impacted other infectious diseases, these results shed light on the need for the continuous surveillance of GBS among pregnant women in the post-pandemic era.
RESUMO
OBJECTIVES: To examine the performance of the Fetal Medicine Foundation (FMF) 2012 predictive model and of isolated biophysical markers (uterine artery pulsatility index and mean arterial pressure) for small-for-gestational-age (SGA), in patients from Rio de Janeiro, Brazil. METHODS: For this cross-sectional study, SGA was diagnosed when a newborn presented birth weight below the fifth percentile for gestational age. FMF2012 algorithm sensitivity and specificity, positive (PPV) and negative (NPV) predictive value, positive likelihood ratio (LR +) and area under the ROC curve (AUC) were calculated to predict total and preterm SGA (SGA < 37). The performance of isolated biophysical markers - mean arterial pressure (MAP) and mean uterine artery pulsatility index (UtAPI) were studied. RESULTS: The final sample consisted of 1480 cases: 69 (4.6%) developed SGA, including 12 patients (0.8%) who were SGA < 37. The AUC showed that the performances of the FMF2012 combined model for SGA prediction was 0.687 and for preterm SGA was 0.824. With risk cutoff of 1:150, SGA screening yielded the following: sensitivity, 47%; specificity, 75%; LR +, 1.88; PPV, 8.66%; NPV, 96.72%. When screening for preterm SGA, we found sensitivity 66.6%, specificity 74.59%, LR +: 2.58, PPV 2%, and NPV 99.63%. CONCLUSIONS: Performance of the FMF2012 algorithm in predicting SGA in our population was similar to that obtained in the reference population, according to sensitivity, but our false positive rate is significantly higher than the reference population.

Gestational trophoblastic neoplasia (GTN) is a rare tumor that originates from pregnancy that includes invasive mole, choriocarcinoma (CCA), placental site trophoblastic tumor and epithelioid trophoblastic tumor (PSTT/ETT). GTN presents different degrees of proliferation, invasion and dissemination, but, if treated in reference centers, has high cure rates, even in multi-metastatic cases. The diagnosis of GTN following a hydatidiform molar pregnancy is made according to the International Federation of Gynecology and Obstetrics (FIGO) 2000 criteria: four or more plateaued human chorionic gonadotropin (hCG) concentrations over three weeks; rise in hCG for three consecutive weekly measurements over at least a period of 2 weeks or more; and an elevated but falling hCG concentrations six or more months after molar evacuation. However, the latter reason for treatment is no longer used by many centers. In addition, GTN is diagnosed with a pathological diagnosis of CCA or PSTT/ETT. For staging after a molar pregnancy, FIGO recommends pelvic-transvaginal Doppler ultrasound and chest X-ray. In cases of pulmonary metastases with more than 1 cm, the screening should be complemented with chest computed tomography and brain magnetic resonance image. Single agent chemotherapy, usually Methotrexate (MTX) or Actinomycin-D (Act-D), can cure about 70% of patients with FIGO/World Health Organization (WHO) prognosis risk score ≤ 6 (low risk), reserving multiple agent chemotherapy, such as EMA/CO (Etoposide, MTX, Act-D, Cyclophosphamide and Oncovin) for cases with FIGO/WHO prognosis risk score ≥ 7 (high risk) that is often metastatic. Best overall cure rates for low and high risk disease is close to 100% and > 95%, respectively. The management of PSTT/ETT differs and cure rates tend to be a bit lower. The early diagnosis of this disease and the appropriate treatment avoid maternal death, allow the healing and maintenance of the reproductive potential of these women.
RESUMO
Objective: To evaluate the impacts of maternal risk factors described by the Fetal Medicine Foundation's 2012 algorithm (FMF2012) in a Brazilian population. Methods: All singleton pregnancies submitted to first-trimester preeclampsia (PE) screening using the FMF2012 algorithm were considered for study inclusion. Maternal factors, recorded via a patient questionnaire, were described and compared between PE outcome groups. A Gaussian regression model was derived to measure the effects of maternal factors, and to identify factors that contributed significantly (p < .05) to the alteration of gestational age at delivery, in pregnancies with PE. Results: Of the 1934 cases considered for study inclusion, the final sample consisted of 1531 cases. The sample included 120 (7.8%) cases of PE, of which 26 (1.7%) were preterm PE (PE < 37 weeks) and 11 (0.72%) were early PE (PE < 34 weeks). The PE rate did not differ according to ethnicity, smoking, family history of PE, or use of assisted reproductive technology. Significant differences (p < .05) between the normal and PE groups in maternal age, maternal weight, previous history of PE, chronic hypertension, and types 1 and 2 diabetes were detected. Conclusions: The significance and magnitude of associations of maternal factors in our sample differed from those incorporated in the FMF2012 model, implying the need to derive a fitted model for our population.

OBJECTIVE: To evaluate uterine evacuation of patients with molar pregnancy, comparing manual with electric vacuum aspiration. METHODS: This is a retrospective cohort study of patients with molar pregnancy followed at the Rio de Janeiro Trophoblastic Disease Center from January 2007 to December 2016. The individual primary study outcomes were incomplete uterine evacuation, uterine perforation, development of uterine synechia, and development of postmolar gestational trophoblastic neoplasia. Secondary endpoints were other features of the perioperative outcomes (operative time, rate of transfusion, hemoglobin change, length of stay) and the clinical course of neoplasia (Prognostic Risk Score, presence of metastases, time to remission, and need for multiagent chemotherapy). RESULTS: Among 1,727 patients with molar pregnancy, 1,206 underwent electric vacuum aspiration and 521 underwent manual vacuum aspiration. After human chorionic gonadotropin normalization, patients with benign molar pregnancy were followed for 6 months and patients treated for gestational trophoblastic neoplasia were followed for 12 months. Baseline risk factors for gestational trophoblastic neoplasia and demographic features were similar between the treatment groups. Uterine synechia developed less frequently after manual vacuum aspiration than after electric vacuum aspiration, 6 of 521 vs 63 of 1,206 (adjusted odds ratio [OR] 0.21, 95% CI 0.09-0.49), despite no differences in the occurrence of incomplete uterine evacuation, 65 of 521 vs 161 of 1,206 (adjusted OR 0.93, 95% CI 0.69-1.27), development of postmolar gestational trophoblastic neoplasia, 90 of 521 vs 171 of 1,206 (adjusted OR 1.26, 95% CI 0.96-1.67), or the need for multiagent chemotherapy, 22 of 521 vs 41 of 1,206 (adjusted OR 0.81, 95% CI 0.73-1.28). CONCLUSION: Manual vacuum aspiration appears to be similar to electric vacuum aspiration for treatment of molar pregnancy and may be associated with less development of uterine synechia.

Abstract Objective To evaluate the efficacy of immunotherapy for GTN treatment after methotrexate-resistance or in cases of multiresistant disease, through a systematic review, as well as to present the first 4 Brazilian cases of immunotherapy for GTN treatment. Methods Three independent researchers searched five electronic databases (EMBASE, LILACS, Medline, CENTRAL and Web of Science), for relevant articles up to February/2023 (PROSPERO CRD42023401453). The quality assessment was performed using the Newcastle Ottawa scale for case series and case reports. The primary outcome of this study was the occurrence of complete remission. The presentation of the case reports was approved by the Institutional Review Board. Results Of the 4 cases presented, the first was a low-risk GTN with methotrexate resistance unsuccessfully treated with avelumab, which achieved remission with sequential multiagent chemotherapy. The remaining 3 cases were high-risk multiagent-resistant GTN that were successfully treated with pembrolizumab, among which there were two subsequent gestations, one of them with normal pregnancy and healthy conceptus. Regarding the systematic review, 12 studies were included, only one of them on avelumab, showing a 46.7% complete remission rate. The remaining 11 studies were on pembrolizumab, showing an 86.7% complete remission rate, regardless of tumor histology. Both immunotherapies showed good tolerability, with two healthy pregnancies being recorded: one after avelumb and another after pembrolizumab. Conclusion Immunotherapy showed effectiveness for GTN treatment and may be especially useful in cases of high-risk disease, where pembrolizumab achieves a high therapeutic response, regardless of the histological type, and despite prior chemoresistance to multiple lines of treatment.
RESUMO
Arboviruses are emerging infectious diseases with the ability to expand geographically and rapidly affect large populations. The recent epidemic caused by the Zika virus in the Americas and congenital Zika syndrome associated with maternal infection has called out attention to the importance of studying arboviruses during pregnancy. This is a review on selected arboviruses infections during gestation, including Zika, Chikungunya, Dengue and Yellow Fever viruses. Issues such as historical overview, pathogenesis, transmission, clinical conditions, diagnosis, treatment and prevention are addressed.
RESUMO
Twin molar pregnancy with a hydatidiform mole and a coexisting live fetus is a rare form of gestational trophoblastic disease associated with an increased risk of obstetric complications and poor perinatal outcome. Prenatal diagnosis is essential for couple counseling and follow-up in Tertiary Reference Centers. Magnetic resonance imaging is important for the diagnostic differentiation of placental mesenchymal dysplasia and exclusion of myometrial invasion. Here we present a case of twin molar pregnancy with a hydatidiform mole and a coexisting live fetus diagnosed at gestational week 14 using two-dimensional (2D) and three-dimensional (3D) ultrasound and magnetic resonance imaging. We also describe the obstetric management and postmolar follow-up.
RESUMO
Preeclampsia (PE) prevalence studies in Brazil are both scarce and not divided in accordance with gestational age at delivery. We accessed PE prevalence according to delivery before 34, 37 and 42weeks in a cross-sectional study including 4464 single deliveries. PE was diagnosed in 301 cases (6.74%); Prevalence of PE was 0.78%; 1.92% and 6.74% according to deliveries before 34, 37 and 42weeks. PE was associated with fetal death, prematurity and small for gestational age newborns.

Gestational trophoblastic disease is an abnormality of pregnancy that encompasses a group of diseases that differ from each other in their propensity for regression, invasion, metastasis, and recurrence. In the past, it was common for patients with molar pregnancy to present with marked symptoms: copious bleeding; theca lutein cysts; uterus larger than appropriate for gestational age; early preeclampsia; hyperemesis gravidarum; and hyperthyroidism. Currently, with early diagnosis made by ultrasound, most patients are diagnosed while the disease is still in the asymptomatic phase. In cases of progression to trophoblastic neoplasia, staging-typically with Doppler flow studies of the pelvis and chest X-ray, although occasionally with computed tomography or magnetic resonance imaging-is critical to the choice of an appropriate antineoplastic therapy regimen. Because it is an unusual and serious disease that affects women of reproductive age, as well as because its appropriate treatment results in high cure rates, it is crucial that radiologists be familiar with gestational trophoblastic disease, in order to facilitate its early diagnosis and to ensure appropriate follow-up imaging.
Doença trofoblástica gestacional é anomalia da gravidez que engloba um grupo de doenças derivadas do trofoblasto, diferentes entre si na propensão para regressão, invasão, metástase e recidiva. No passado, era comum a paciente portadora de gravidez molar apresentar sintomas exuberantes: hemorragia copiosa, cistos tecaluteínicos, útero aumentado para a idade gestacional, pré-eclâmpsia precoce, hiperêmese e hipertireoidismo. Atualmente, com o diagnóstico precoce feito pela ultrassonografia, a maioria das pacientes é diagnosticada ainda na fase assintomática. Nos casos em que há progressão para neoplasia trofoblástica gestacional, o estadiamento feito com a dopplerfluxometria pélvica e a radiografia de tórax, eventualmente com a tomografia computadorizada e a ressonância magnética, é fundamental na avaliação da escolha do tratamento antineoplásico. Por ser uma doença incomum e grave, que acomete mulheres no menacme, mas cujo tratamento adequado determina elevadas taxas de cura, é fundamental que os radiologistas estejam familiarizados com essa entidade clínica, a fim de auxiliar no diagnóstico precoce e promover seu correto acompanhamento imaginológico.
RESUMO
We report here a case of gestational trophoblastic neoplasia after spontaneous normalization of human chorionic gonadotropin in a patient with a partial hydatidiform mole. This is the second occurrence of this event to be reported and the first one with proven immunohistochemical evidence. Besides showing the treatment for this pregnancy complication, this case report discusses the possibility of reducing the duration of post-molar follow-up, as well as strategies for early recognition of gestational trophoblastic neoplasia after spontaneous remission of molar pregnancy.

Apoptose, ou morte celular programada, é um mecanismo fisiológico universal entre mamíferos que regula o equilíbrio entre proliferação e morte celular a fim de manter a homeostase tecidual. Nesse processo, a apoptose poderá ser iniciada intrinsicamente por via mitocondrial ou, extrinsecamente, mediada por sinalização via receptor de morte ou em resposta a elementos exógenos como citocinas e processos não excludentes, complementares e com ativação cruzada. As moléculas envolvidas no controle das vias de ativação da apoptose são as proteínas anti, pró-apoptóticas e caspases. Esse fenômeno biológico, além de desempenhar um papel importante no controle de diversos processos vitais, está associado a inúmeras complicações da gravidez como toxemia, crescimento intrauterino restrito, parto pré-termo, diabetes gestacional, abortamento, gravidez ectópica e a transformação maligna da mola hidatiforme. No denominador comum dessas doenças está o desconhecimento de sua etiopatogenia e o desenvolvimento/funcionamento placentário anormal. Compreender todas essas alterações deverá interessar não apenas ao pesquisador dessas moléstias, mas também aos clínicos que tratam essas doenças no intuito de se incorporar novas tecnologias na rotina médica e na melhoria das perspectivas prognósticas e terapêuticas dentro da obstetrícia.(AU)
Apoptosis, or programmed cell death, is a universal physiological mechanism in mammals, which regulates the balance between cell proliferation and death in order to maintain tissue homeostasis. In this process, apoptosis can be initiated intrinsically or extrinsically by mitochondrial pathway, mediated by death receptor signaling or in response to exogenous factors such as cytokines and processes not mutually exclusive, complementary and cross-activation. The molecules involved in the control of apoptosis activation pathways are anti and pro-apoptotic proteins as well as caspases. This biological phenomenon, besides play an important role in the control of many vital processes, is associated with many complications of pregnancy such as toxemia, intrauterine growth, preterm birth, gestational diabetes, miscarriage, ectopic pregnancy and malignant in transformation hydatiform mole. The common denominator of these diseases is the lack of knowledge about its pathogenesis and development/abnormal placental function. Understand all these changes should interest not only to the researchers, but also for clinicians who treat these diseases in order to incorporate new technologies in the medical routine and in improving prognostic and therapeutic perspectives in obstetrics.(AU)
