Abstract Objectives Hospitalization during pregnancy and childbirth increases the risk of Venous Thromboembolism Risk (VTE). This study applied a VTE risk score to all hospitalized pregnant women to ascertain its effectiveness in preventing maternal death from VTE until 3 months after discharge. Methods In this interventional study, patients were classified as low- or high-risk according to the VTE risk score (Clinics Hospital risk score). High-risk patients (score ≥ 3) were scheduled for pharmacological Thromboprophylaxis (TPX). Interaction analysis of the main risk factors was performed using Odds Ratio (OR) and Poisson regression with robust variance. Results The data of 10694 cases (7212 patients) were analyzed; 1626 (15.2%, 1000 patients) and 9068 (84.8%, 6212 patients) cases were classified as high-risk (score ≥ 3) and low-risk (score < 3), respectively. The main risk factors (Odds Ratio, 95% Confidence Interval) for VTE were age ≥ 35 and < 40 years (1.6, 1.4-1.8), parity ≥ 3 (3.5, 3.0-4.0), age ≥ 40 years (4.8, 4.1-5.6), multiple pregnancies (2.1, 1.7-2.5), BMI ≥ 40 kg/m2 (5.1, 4.3-6.0), severe infection (4.1, 3.3-5.1), and cancer (12.3, 8.8-17.2). There were 10 cases of VTE: 7/1636 (0.4%) and 3/9068 (0.03%) in the high- and low-risk groups, respectively. No patient died of VTE. The intervention reduced the VTE risk by 87%; the number needed to treat was 3. Conclusions This VTE risk score was effective in preventing maternal deaths from VTE, with a low indication for TPX. Maternal age, multiparity, obesity, severe infections, multiple pregnancies, and cancer were the main risk factors for VTE. .

SUMMARY OBJECTIVE: The objective of this study was to compare the nutritional status and dietary intake of pregnant women with sickle cell disease (SS hemoglobinopathy and SC hemoglobinopathy) to healthy controls and report the maternal and perinatal outcomes. METHODS: This is a prospective, longitudinal cohort study. Pregnant women with a diagnosis of sickle cell disease and control group were recruited in an outpatient clinic of a tertiary care hospital in São Paulo, Brazil. Maternal anthropometric data and dietary intake data were collected at the second and third trimesters. RESULTS: A total of 49 pregnancies complicated by sickle cell disease were included. Prepregnancy body mass index was significantly lower in the SS hemoglobinopathy group (n=26, median 20.3 kg/m2) than the SC hemoglobinopathy group (n=23, 22.7 kg/m2) or control group (n=33, 23.2 kg/m2, p<0.05). The prepregnancy nutritional status revealed significantly more women classified as underweight in the SS hemoglobinopathy group (15.4%) than in the SC hemoglobinopathy group (4.4%) and control group (1.6%, p=0.009). In the second trimester, maternal protein intake was significantly lower in SS hemoglobinopathy (73.2 g/day) and SC hemoglobinopathy (68.8 g/day) than in the control group (95.7 g/day, p=0.004). In the third trimester, only SS hemoglobinopathy mothers showed dietary intake of protein significantly lower than that of the controls (67.5 g/day vs. 92.8 g/day, p=0.02). Vitamin A and E consumption was also reduced in the third trimester in the SS hemoglobinopathy group (p<0.05). CONCLUSION: The nutritional status of pregnant women with SS hemoglobinopathy is characterized by a state of undernutrition. The lower protein intake in the second and third trimesters of pregnant women with SS hemoglobinopathy may contribute to this condition. Undernourishment is a serious complication of sickle cell disease, primarily during pregnancy, and it should be addressed during the prenatal period.

OBJECTIVES: Hospitalized patients with cancer are at high risk of developing venous thromboembolism, and the risk increases with pregnancy. The aim of this study was to apply a thromboprophylaxis protocol with a venous thromboembolism risk score for hospitalized pregnant women with cancer and to evaluate the effects on maternal morbidity and mortality. METHODS: A longitudinal and prospective study was conducted from December 2014 to July 2016. The venous thromboembolism risk score was modified from the guidelines of the Royal College of Obstetricians and Gynaecologists. Patients were classified as low (score <3) or high risk (score ≥3). The high-risk group received thromboprophylaxis with low-molecular-weight heparin, unless the patient had a contraindication for anticoagulation. One patient could have undergone more than one evaluation. RESULTS: Fifty-two ratings were descriptively analyzed: 34 (65.4%) were classified as high risk, and 28/34 (82.3%) received low-molecular-weight heparin, 1 received unfractionated heparin, and 5 did not receive intervention. Most patients (23/52; 44.2%) had breast cancer. The main risk factors for venous thromboembolism in the high-risk group were chemotherapy (within 6 months; 22/34; 64.7%). No patient exhibited venous thromboembolism, adverse effects of anticoagulation or death up to three months after hospitalization. CONCLUSIONS: Most pregnant women with cancer had a high risk for venous thromboembolism at the time of hospitalization. Breast cancer was the most prevalent cancer, and recent chemotherapy was the main risk factor for anticoagulation. The application of a thromboprophylaxis protocol and determination of a venous thromboembolism risk score for these patients was useful for the prevention of maternal morbidity and mortality due to venous thromboembolism.

OBJETIVO: Descrever desfechos obstétricos e frequência de trombofilias em gestantes com óbito fetal de repetição após a 20a semana de gravidez. MÉTODOS: Avaliação de desfechos obstétricos em uma série de casos de gestantes com óbito fetal de repetição após a 20a semana de gestação, acompanhadas de 2001 a 2013. A atividade de antitrombina, atividade da proteína C e S, presença de fator V de Leiden, presença da mutação do gene de protrombina e presença de síndrome antifosfolípide foram avaliadas nessas pacientes. RESULTADOS: Foram incluídas 20 pacientes que tinham óbito fetal de repetição. Trombofilias foram encontradas em 11 delas, sendo 7 diagnosticadas como síndrome antifosfolípide, 3 como deficiência de proteína S e 1 como mutação do gene da protrombina. Todas foram tratadas com heparina subcutânea (heparina não fracionada ou enoxaparina) e 14 delas com ácido acetilsalicílico (AAS) durante toda a gestação. Complicações obstétricas ocorreram em 15 pacientes e incluíram: restrição de crescimento fetal intrauterino (25%), placenta prévia (15%), índice de líquido amniótico diminuído (25%), pré-eclâmpsia grave (10%), sofrimento fetal (5%) e óbito fetal (5%). A idade gestacional média do parto foi de 35,8±3,7 semanas e o peso dos recém-nascidos foi, em média, de 2.417,3±666,2 g. CONCLUSÃO: A pesquisa de trombofilias deve ser realizada em todas as gestantes com óbitos fetais de repetição após a 20a semana de gestação, como forma de identificar possíveis fatores causas passíveis de tratamento.

PURPOSE: To evaluate pregnancy outcome and thrombophilia frequency in women with recurrent fetal death. METHODS: Evaluation of obstetric outcomes in a retrospective cohort of pregnant women with recurrent stillbirth after the 20th week, from 2001 to 2013. Antithrombin activity, protein C and S activity, factor V Leiden, prothrombin gene mutation and antiphospholipid syndrome were analyzed. RESULTS: We included 20 patients who had recurrent fetal death. Thrombophilia were found in 11 of them, 7 diagnosed with antiphospholipid syndrome, 3 with protein S deficiency and 1 with prothrombin gene mutation. All of them were treated with subcutaneous heparin (unfractionated heparin or enoxaparina) and 14 of them with acetylsalicylic acid (AAS) during pregnancy. Obstetric complications occurred in 15 patients and included: intrauterine fetal growth restriction (25%), placenta previa (15%), reduced amniotic fluid index (25%), severe preeclampsia (10%), fetal distress (5%), and stillbirth (5%). The mean gestational age at delivery was 35.8±3.7 weeks and newborn weight averaged 2,417.3±666.2 g. CONCLUSION: Thrombophilia screening should be performed in all pregnant women with recurrent fetal death after the 20th week as a way to identify possible causal factors suitable for treatment.

CONTEXTO Anemia falciforme homozigótica (SS) complicada por sequestro esplênico agudo em adultos é evento raro, e nunca foi relatado durante a gravidez. RELATO DO CASO Uma mulher de 25 anos, portadora de doença falciforme homozigótica (SS), com 32 semanas de gestação, foi internada apresentando fraqueza, dor abdominal, febre e hemoglobina de 2,4 g/dl. Frequência cardíaca fetal anormal foi detectada pela cardiotocografia e a paciente recebeu 5 unidades de concentrado de hemácias. Cesariana foi realizada com 37 semanas. Mãe e filho receberam alta em bom estado geral. CONCLUSÃO Este relato de caso demonstra a importância da transfusão imediata para o tratamento de sofrimento fetal nos casos de sequestro esplênico durante a gestação. Este tratamento é imprescindível para se evitarem complicações maternas e fetais.

CONTEXT Homozygous (SS) sickle-cell anemia complicated by acute splenic sequestration in adults is a rare event, and it has never been reported during pregnancy. CASE REPORT A 25-year-old woman with homozygous (SS) sickle-cell disease was hospitalized at 32 weeks' of gestation presenting weakness, abdominal pain, fever and hemoglobin of 2.4 g/dl. Abnormal fetal heart rate was detected by means of cardiotocography, and 5 units of packed red cells were transfused. Cesarean was performed at 37 weeks. Both mother and baby were discharged in a good general condition. CONCLUSION This case report demonstrates the importance of immediate blood transfusion for treatment of fetal distress in cases of splenic sequestration during pregnancy. This treatment is essential for avoiding maternal and fetal complications.

OBJETIVO: O presente trabalho tem como objetivo descrever o manejo do pré-natal e do parto em pacientes portadoras de hepatite autoimune associada à plaquetopenia moderada ou grave. MÉTODOS: Este trabalho foi realizado em hospital universitário, de nível terciário. Foram analisadas, retrospectivamente, 13 gestações em dez pacientes com diagnóstico de hepatite autoimune complicadas pela plaquetopenia. Os critérios de inclusão foram: diagnóstico clínico de hepatite autoimune, plaquetopenia moderada ou grave (contagem de plaquetas < 100 x 103/mm3), idade gestacional ao nascimento acima de 22 semanas e pacientes acompanhadas por equipe especializada da instituição. As variáveis estudadas incluíram idade materna, paridade, os regimes de tratamento, contagem de plaquetas, exames para investigação da função hepática, tipo de parto, peso ao nascer e idade gestacional no momento do parto. RESULTADOS: A média da idade materna foi de 24,5 anos (DP = 5,3) e seis (50%) ocorreram em nulíparas. Durante a gravidez, a monoterapia com prednisona foi adotada em 11 (92%) casos. De acordo com o perfil de autoanticorpos, sete (58%) gestações possuíam diagnóstico de hepatite autoimune tipo I, duas (17%) do tipo II e três (25%) eram portadoras de hepatite crônica criptogênica (títulos de autoanticorpos indetectáveis). A hipertensão portal foi caracterizada em 11 (92%) gestações. A idade gestacional média no parto foi de 36,9 semanas (DP = 1,5 semana), com média de peso ao nascer de 2446g (DP = 655g), sendo oito (67%) pequenos para a idade gestacional. No momento do parto, a plaquetopenia grave foi caracterizada em quatro (33%) casos e a cesárea foi realizada em sete (58%). As complicações no parto ocorreram em três casos (25%), uma paciente apresentou atonia uterina e duas, hematoma perineal. Não houve morte materna ou perinatal. CONCLUSÃO: As complicações em pacientes plaquetopênicas com hepatite autoimune são elevadas, no entanto, com os cuidados e atenção necessários, podem ser contornáveis. A associação de duas patologias graves parece aumentar o risco de prematuridade e restrição do crescimento fetal, demandando atenção pré-natal especializada, bem como vigilância do bem-estar do concepto.

OBJECTIVE: To describe the management of prenatal care and delivery in patients bearing autoimmune hepatitis associated with moderate or severe thrombocytopenia. METHODS: This study was performed in a tertiary level university hospital. Thirteen pregnancies in ten patients diagnosed with autoimmune hepatitis, complicated by thrombocytopenia, were retrospectively analyzed. The inclusion criteria were as follows: clinical diagnosis of autoimmune hepatitis, moderate or severe thrombocytopenia (platelet count < 100 x 103/mm3), gestational age at birth over 22 weeks, and patient followed-up by a specialized team at the institution. The variables studied were: maternal age, parity, treatment regimen, platelet count, examinations for investigation of hepatic function, type of delivery, weight at birth, and gestational age at the time of delivery. RESULTS: The average maternal age was 24.5 years (SD = 5.3) and six (50%) occurred in nulliparous women. During pregnancy, monotherapy with prednisone was adopted in 11 cases (92%). According to the autoantibody profiles, seven pregnancies (58%) had the autoimmune hepatitis type I diagnosis, two pregnancies had type II (17%), and three pregnancies (25%) had cryptogenic chronic hepatitis (undetectable titers of autoantibodies). Portal hypertension was featured in 11 pregnancies (92%). The average gestational age at delivery was 36.9 weeks (SD = 1.5 weeks), with an average weight at birth of 2,446 g (SD = 655 g). Eight infants (67%) were small for gestational age. At the time of delivery, severe thrombocytopenia was featured in four cases (33%) and cesarean surgery was performed in seven cases (58%). Complications at delivery occurred in three cases (25%), one patient presented uterine atony, and two patients presented perineal bruising. There was no perinatal or maternal death. CONCLUSION: The complications of thrombocytopenic patients with autoimmune hepatitis are elevated; nevertheless, with appropriate attention and care, they can be resolved. The association between two severe pathologies appears to increase the risk of prematurity and fetal growth restriction, demanding specialized prenatal care, as well as surveillance of newborn well-being.

OBJETIVO: Analisar os resultados da avaliação da vitalidade fetal em gestações complicadas por plaquetopenia materna moderada ou grave. MÉTODOS: No período de abril de 2001 a julho de 2011, foram analisados, retrospectivamente, os dados de prontuários de 96 gestantes com diagnóstico de plaquetopenia na gestação. Foram analisados os seguintes exames de avaliação da vitalidade fetal realizados no período anteparto: cardiotocografia, perfil biofísico fetal, índice de líquido amniótico e doplervelocimetria das artérias umbilicais. RESULTADOS: Foram analisadas 96 gestações com os seguintes diagnósticos: plaquetopenia gestacional (n=37, 38,5%), hiperesplenismo (n=32, 33,3%), púrpura trombocitopenica imune (PTI, n=14, 14,6%), plaquetopenia imune secundária (n=6, 6,3%), aplasia medular (n=3, 3,1%) e outros (n=4, 4,1%). A cardiotocografia apresentou resultado normal em 94% dos casos, o perfil biofísico fetal com índice 8 ou 10 em 96,9% e o índice de líquido amniótico >5,0 cm em 89,6%. A doplervelocimetria da artéria umbilical apresentou resultado normal em 96,9%. Na análise dos principais grupos de plaquetopenia, constatou-se que o diagnóstico de oligohidrâmnio foi significativamente mais frequente no grupo com PTI (28,6%) quando comparado aos demais (gestacional: 5,4% e hiperesplenismo: 9,4%, p=0,04). CONCLUSÕES: O presente estudo permitiu concluir que, nas gestações complicadas pela plaquetopenia materna moderada ou grave, apesar do bem-estar fetal manter-se preservado na grande maioria dos casos, em gestantes com PTI é importante o seguimento da vitalidade fetal com ênfase na avaliação do volume de líquido amniótico, devido à sua associação com a oligohidramnia.

PURPOSE: To analyze the results of assessment of fetal well-being in pregnancies complicated by moderate or severe maternal thrombocytopenia. METHODS: Data from April 2001 to July 2011 of 96 women with a diagnosis of thrombocytopenia in pregnancy were retrospectively analyzed. We analyzed the following tests performed during the antepartum period for fetal assessment: cardiotocography, fetal biophysical profile, amniotic fluid index and umbilical artery Doppler velocimetry. RESULTS: A total of 96 pregnancies with the following diagnoses were analyzed: gestational thrombocytopenia (n=37, 38.5%) hypersplenism (n=32, 33.3%), immune thrombocytopenic purpura (ITP, n=14, 14.6%), secondary immune thrombocytopenia (n=6, 6.3%), bone marrow aplasia (n=3, 3.1%), and others (n=4, 4.1%). Cardiotocography showed normal results in 94% of cases, a fetal biophysical profile with an index of 8 or 10 in 96.9% and an amniotic fluid index >5.0 cm in 89.6%. Doppler umbilical artery velocimetry showed normal results in 96.9% of cases. In the analysis of the major groups of thrombocytopenia, the diagnosis of oligohydramnios was found to be significantly more frequent in the group with ITP (28.6%) compared to the other groups (gestational thrombocytopenia: 5.4% and hypersplenism: 9.4%, p=0.04). CONCLUSIONS: This study indicates that in pregnancies complicated by moderate or severe maternal thrombocytopenia, even though the fetal well-being remains preserved in most cases, fetal surveillance is important in pregnant women with ITP, with emphasis on amniotic fluid volume evaluation due to its association with oligohydramnios.

RESUMO OBJETIVO: Descrever as complicações maternas e os resultados perinatais entre as gestantes com diagnóstico de leucemia que foram acompanhadas no pré-natal e no parto em hospital universitário. MÉTODOS: Estudo retrospectivo do período de 2001 a 2011, que incluiu 16 gestantes portadoras de leucemia acompanhadas pela equipe de pré-natal especializado em hemopatias e gestação. Nas leucoses agudas, diagnosticadas após o primeiro trimestre, a recomendação foi realizar a quimioterapia apesar da gestação em curso. Nas gestantes com leucoses crônicas, quando controladas do ponto de vista hematológico, foram mantidas sem medicação durante a gravidez, ou, foi introduzida terapêutica antineoplásica após o primeiro trimestre. Foram analisadas as complicações maternas e os resultados perinatais. RESULTADOS: A leucemia linfoide aguda (LLA) foi diagnosticada em cinco casos (31,3%), a leucemia mieloide aguda (LMA) em dois casos (12,5%) e a leucemia mieloide crônica (LMC) em nove casos (56,3%). Nos casos de leucemias agudas, dois (28,6%) casos foram diagnosticados no primeiro trimestre, dois (28,6%) no segundo e três (42,9%) no terceiro. Duas gestantes com LLA diagnosticada no primeiro trimestre optaram pelo aborto terapêutico. Quatro casos de leucemia aguda receberam tratamento quimioterápico na gestação, com diagnóstico estabelecido após a 20ª semana. Em um caso de LLA com diagnóstico tardio (30ª semana) a quimioterapia foi iniciada após o parto. Todas as gestantes com leucemia aguda evoluíram com anemia e plaquetopenia, quatro casos (57,1%) evoluíram com neutropenia febril. Das gestantes com LMC, quatro utilizavam mesilato de imatinibe quando engravidaram, três delas suspenderam no primeiro trimestre e uma no segundo. Durante a gravidez, três (33,3%) não necessitaram de terapêutica antineoplásica após suspensão do imatinibe; e em seis (66,7%) foram utilizadas as seguintes drogas: interferon (n=5) e/ou hidroxiureia (n=3). No grupo de gestantes com LMC, verificou-se a ocorrência de anemia em quatro casos (44,4%) e plaquetopenia em um (11,1%). Quanto aos resultados perinatais, nas gestações complicadas pela leucemia aguda, a média da idade gestacional no parto foi de 32 semanas (desvio padrão - DP=4,4) e a média do peso do recém-nascido foi 1476 g (DP=657 g). Houve 2 (40,0%) óbitos perinatais (um fetal e um neonatal). Nas gestações complicadas pela LMC, a média da idade gestacional no parto foi de 37,6 semanas (DP=1,1) e a média do peso do recém-nascido foi 2870 g (DP=516 g); não houve morte perinatal e nenhuma anomalia fetal foi detectada. CONCLUSÕES: É elevada a morbidade materna e fetal nas gestações complicadas pela leucemia aguda; enquanto que, nas complicadas pela LMC, o prognóstico materno e fetal parece ser mais favorável, com maior facilidade no manejo das complicações.

PURPOSE: To describe the maternal and perinatal outcomes of pregnant women diagnosed with leukemia who were followed up for prenatal care and delivery at a university hospital. METHODS: A retrospective study of the period from 2001 to 2011, which included 16 pregnant women with a diagnosis of leukemia followed by antenatal care specialists in hematological diseases and pregnancy. For acute leukemia diagnosed after the first trimester, the recommendation was to perform chemotherapy despite the current pregnancy. For chronic leukemia, patients who were controlled in hematological terms were maintained without medication during pregnancy, or chemotherapy was introduced after the first trimester. We analyzed the maternal and perinatal outcome. RESULTS: Acute lymphoblastic leukemia (ALL) was diagnosed in five cases (31.3%), acute myeloid leukemia (AML) in two cases (12.5%) and chronic myeloid leukemia (CML) in nine cases (56.3%). Of the cases of acute leukemia, two (28.6%) were diagnosed in the first trimester, two (28.6%) in the second and three (42.9%) in the third. Two patients with ALL diagnosed in the first trimester opted for therapeutic abortion. Four patients with acute leukemia received chemotherapy during pregnancy, with a diagnosis established after the 20th week. In one case of ALL with a late diagnosis (30 weeks), chemotherapy was started after delivery. All pregnant women with acute leukemia developed anemia and thrombocytopenia, and four (57.1%) developed febrile neutropenia. Of nine pregnant women with CML, four were treated with imatinib mesylate when they became pregnant, with treatment being interrupted in the first trimester in three of them and in the second trimester in one. During pregnancy, three patients (33.3%) required no chemotherapy after discontinuation of imatinib, and six (66.7%) were treated with the following drugs: interferon (n=5) and/or hydroxyurea (n=3 ). In the group of pregnant women with CML, anemia occurred in four (44.4%) cases and thrombocytopenia in one (11.1%). The perinatal outcomes of pregnancies complicated by acute leukemia were as follows: mean gestational age at delivery was 32 weeks (standard deviation - SD=4.4) and the mean birth weight was 1476 g (SD=657 g), there were 2 (40.0%) perinatal deaths (a fetal one and a neonatal one). In pregnancies complicated by CML, the mean gestational age at delivery was 37.6 weeks (SD=1.1) and the mean birth weight was 2870 g (SD=516 g). There was no perinatal death and no fetal abnormality was detected. CONCLUSIONS: Maternal and fetal morbidity is high in pregnancies complicated by acute leukemia. Whereas, in pregnancies complicated by CML, the maternal and fetal prognosis appears to be more favorable, with greater ease in management of complications.

OBJETIVO: avaliar os resultados maternos e perinatais de gestações complicadas por doenças falciformes, comparando-as com portadoras de traço falciforme. MÉTODOS: este estudo é uma coorte retrospectiva, abrangendo o período de Março de 2001 a Abril de 2008, tendo sido incluídas todas as gestantes portadoras de doença falciforme (n=42) acompanhadas em hospital universitário da região sudeste do Brasil. Os resultados maternos e perinatais foram comparados com os de gestantes portadoras de traço falciforme (n=56) acompanhadas no mesmo serviço. RESULTADOS:a hemoglobinopatia SS foi diagnosticada em 42 gestantes (82,4%) e a SC em nove (17,6%). A idade materna foi significativamente menor no grupo com doença falciforme (média=26,0; SD=4,3) quando comparadas às com traço falciforme (média=28,7, DP=7,1; p=0,018). As seguintes complicações maternas foram significativamente mais frequentes no grupo com doença falciforme em comparação ao grupo com traço falciforme: infecção do trato urinário (25,5 versus 8,9%; p=0,04), pneumonia (23,5 versus 1,8%; p=0,002), hipertensão pulmonar (15,7 versus 0%; p=0,002), e transfusão no parto/pós-parto (33,3 versus 5,4%; p=0,001). Resultados perinatais adversos foram significativamente mais frequentes no grupo com doença falciforme quando comparados ao grupo com traço falciforme: prematuridade (49 versus 25%; p=0,01), média da idade gestacional no parto (35,2 versus 37,9 semanas; p<0,001), diagnóstico de sofrimento fetal (56,9 versus 28,6%; p=0,006), peso do recém-nascido <2.500g (62,7 versus 17,9%; p<0,001), média do peso do recém-nascido (2.183 versus 2.923 g; p<0,001) e recém-nascidos pequenos para a idade gestacional (29,4 versus 10,7%; p=0,02). Duas mortes maternas (3,9%) ocorreram no grupo com doença falciforme. CONCLUSÕES: gestantes portadoras de doença falciforme apresentam maior risco para morbidade materna e resultados perinatais adversos quando comparadas às portadoras de traço falciforme.

PURPOSE: the aim of this study was to describe perinatal and maternal outcomes of pregnancies complicated by sickle cell disease (SCD), comparing to pregnancies of women with sickle cell trait (SCT). METHODS: this was a retrospective cohort study, covering the period from March 2001 to April 2008, which included all pregnant women with SCD (n=42) followed up at a university hospital in the Southeast region of Brazil. The maternal and perinatal outcomes were compared to those of pregnant women with SCT (n=56) who were followed up at the same service. RESULTS:SCD-SS was diagnosed in 42 (82.4%) pregnant women and SC in 9 (17.6%). Mean (±SD) maternal age was significantly lower in the SCD group (26.0 years) compared to SCT women (28.7±7.1 years; p=0.018). The following maternal complications were more common among women with SCD in comparison to SCT: urinary tract infection (25.5 versus 8.9%; p=0.04), pneumonia (23.5 versus 1.8%; p=0.002), pulmonary hypertension (15.7 versus 0%; p=0.002), and blood transfusion during delivery or postpartum (33.3 versus 5.4%; p=0.001). Adverse perinatal outcome was more frequent in the SCD group compared to the SCT group: prematurity (49 versus 25%, p=0.01); mean gestational age at delivery (35.2 versus 37.9 weeks, p<0.001); fetal distress (56.9 versus 28.6%, p=0.006); birth weight <2,500 g (62.7 versus 17.9%, p<0.001); mean birth weight (2,183 versus 2,923 g, p<0.001), and small for gestational age infants (29.4 versus 10.7%, p=0.029). Two maternal deaths (3.9%) occurred in the group with SCD. CONCLUSION: Pregnant women with SCD are at greater risk for maternal morbidity and for adverse perinatal outcomes than women with SCT.

OBJETIVO: Analisar os resultados da avaliação da vitalidade fetal de gestações após gastroplastia com derivação em Y de Roux, verificando as complicações maternas e os resultados perinatais. MÉTODOS: No período de julho de 2001 a setembro de 2009, foram analisados, retrospectivamente, dados de prontuário de pacientes com gestação após gastroplastia com derivação em Y de Roux, acompanhadas em pré-natal especializado e cujo parto foi realizado na instituição. Foram analisados os exames de avaliação da vitalidade fetal (cardiotocografia, perfil biofísico fetal e dopplervelocimetria das artérias umbilicais) realizada na semana anterior ao parto. As variáveis maternas investigadas foram: dados demográficos, complicações clínicas maternas, tipo de parto, complicações no parto e pós-parto, exames hematimétricos maternos e resultados perinatais. RESULTADOS: Trinta gestações após gastroplastia com derivação em Y de Roux foram identificadas e 24 delas foram submetidas à avaliação da vitalidade fetal. Todas as pacientes apresentaram resultados normais na cardiotocografia, no perfil biofísico fetal e na dopplervelocimetria das artérias umbilicais. Houve um caso de oligohidrâmnio. A principal complicação observada foi anemia materna (Hb < 11,0 g/dL, 86,7%). A cesárea foi realizada em 21 pacientes (70%). As complicações do parto incluíram um caso de aderências, um de hematoma e infecção de parede e um de histerectomia pós-parto por miomatose e atonia uterina. A proporção de recém-nascidos pequenos para a idade gestacional foi de 23,3%. CONCLUSÃO: Não houve comprometimento do bem-estar fetal em gestações após gastroplastia com derivação em Y de Roux. A principal complicação materna foi a anemia e essas mulheres requerem aconselhamento nutricional específico com ampla avaliação das deficiências de micronutrientes desde o início da gravidez.

OBJECTIVE: To study fetal vitality assessed in pregnancies after gastroplasty with Roux-en-Y gastric bypass'and verify maternal complications and perinatal results. METHODS: Hospital charts of all pregnancies after gastroplasty with Roux-en-Y gastric bypass were reviewed retrospectively. All cases followed at the specialized prenatal care that gave birth in this institution, between July 2001 and September 2009, were reviewed. The assessment of fetal vitality (cardiotocography, fetal biophysical profile and umbilical artery Doppler velocimetry) performed in the last week before delivery were analyzed. The maternal variables investigated were: demographic data, maternal complications, mode of delivery, complications during delivery and postpartum, maternal blood exams and perinatal results. RESULTS: During the study period 30 pregnancies after gastroplasty with Roux-en-Y gastric bypass were identified and 24 of them had undergone assessment of fetal vitality. All patients presented normal cardiotocography, normal fetal biophysical profile and normal results at the umbilical artery Doppler velocimetry. One case presented with oligohydramnios. The main complication observed was maternal anemia (Hb < 11.0 g/dL, 86.7%). Cesarean section was performed in 21 pregnancies (70%). Delivery complications included one case of adherences, one hematoma and infection of abdominal wall scar and one postpartum hysterectomy for myoma and uterine atony. The proportion of small infants for gestational age was 23.3%. CONCLUSION: Fetal vitality was not compromised in pregnancies after gastroplasty with Roux-en-Y gastric bypass. The main maternal complication was anemia, therefore these women require specific nutritional counseling and a broad evaluation for micronutrient deficiencies at early pregnancy.

OBJETIVOS: avaliar a influência dos níveis de hemoglobina (Hb) materna nos padrões da frequência cardíaca fetal (FCF) e no perfil biofísico fetal (PBF) em gestações a termo. MÉTODOS: gestantes portadoras de anemia (Hb<11,0 g/dL) foram avaliadas prospectivamente, entre a 36ª e a 40ª semana de gestação, no período compreendido entre janeiro de 2008 e março de 2009. O Grupo Controle foi constituído por gestantes de termo, saudáveis, com valores normais de hemoglobina (Hb>11,0 g/dL). Foram excluídos casos com anomalias ou restrição do crescimento fetal. A avaliação da FCF foi realizada pela cardiotocografia computadorizada (Sistema8002-Sonicaid) e análise do traçado com 30 minutos de exame. O PBF foi realizado em todas as pacientes. Foram utilizados os testes t de Student, teste do χ2 e teste exato de Fisher. O nível de significância utilizado foi de 0,05. RESULTADOS: A média da Hb materna no grupo com anemia (n=18) foi de 9,4 g/dL (DP=1,4 g/dL) e no Grupo Controle 12,4 g/dL (DP=1,3 g/dL). Quanto aos parâmetros da cardiotocografia, não foi constatada diferença significativa nas médias entre os grupos com anemia e controle, respectivamente: FCF basal (131,3 bpm versus 133,7 bpm, p=0,5), acelerações da FCF > 10 bpm (7,9 versus. 8,2, p=0,866), acelerações da FCF > 15 bpm (5,2 versus 5,4, p=0,9), episódios de alta variação da FCF (17,1 versus 15,5 min, p=0,5), episódios de baixa variação da FCF (4,4 versus 3,6 min, p=0,6), e variação de curto prazo (10,5 versus 10,9 ms, p=0,5). Em ambos os grupos, todas as pacientes apresentaram PBF normal. CONCLUSÕES: este estudo sugere que a anemia materna leve ou moderada, sem outras comorbidades maternas ou fetais, não se associa a anormalidades nos parâmetros do perfil biofísico fetal e da FCF analisada pela cardiotocografia computadorizada.

PURPOSES: to evaluate the influence of maternal hemoglobin (Hb) levels in the patterns of fetal heart rate (FHR) and in the fetal biophysical profile (FBP) in term gestations. METHODS: pregnant women with anemia (Hb<11.0 g/dL) were prospectively evaluated between the 36th and the 40th week of gestation, from January 2008 to March 2009. The Control Group was composed of term and healthy pregnant women, with normal values of hemoglobin (Hb>11,0 g/dL). Cases of anomalies or fetal growing restrictions were excluded. The FHR evaluation was performed by computerized cardiotocography (8002 System-Sonicaid), and by record analysis during 30 minutes of exam. The FBP was done in all the patients. Student's, χ2 and Fisher's exact tests were used, with 0.05 significance level. RESULTS: The average of maternal Hb in the group with anemia (n=18) was 9.4 g/dL (DP=1.4 g/dL), and in the control group, 12.4g/dL (DP=1.3 g/dL). There has been no significant mean differences between groups concerning the cardiotocography parameters, respectively: basal FHR(131.3 versus 133.7 bpm, p=0.5), FHR accelerations > 10b pm (7.9 versus 8.2, p=0.866), FHR accelerations > 15 bpm (5.2 versus. 5.4, p=0.9), episodes of high variation of the FHR (17.1 versus 15.5 min, p=0,5), episodes of variation of the FHR (4.4 versus 3.6 min, p=06), and short term variation (10.5 versus 10.9 ms, p=0.5). In both groups, all patients presented normal FBP. CONCLUSIONS: this study suggests that light or moderate maternal anemia, without other maternal or fetal comorbidity, is not associated with abnormalities in the parameters of fetal biophysical profile and of the FHR analyzed by computerized cardiotocography.

OBJETIVO: Analisar as complicações maternas associadas ao parto e puerpério, bem como os resultados perinatais, em gestantes portadoras da doença de von Willebrand. MÉTODOS: Foram analisados os prontuários de todas as gestantes com diagnóstico de doença de von Willebrand, cujo parto foi realizado nesta instituição no período compreendido entre março de 2001 e agosto de 2007. Foram investigadas características relativas à via de parto, incidência de complicações hemorrágicas no parto e no puerpério imediato, perfil dos exames laboratoriais maternos e resultados perinatais. As variáveis foram estudadas descritivamente, calculando-se freqüências absolutas e relativas, médias, medianas e desvios padrão. RESULTADOS: Foram revisadas 13 gestações em oito pacientes portadoras da doença. No período ocorreram 13.037 partos na instituição, perfazendo incidência de 0,1%. Seis pacientes (75%) apresentavam o tipo 1 da doença, e duas (25%) o tipo 2. No terceiro trimestre, a média da atividade do fator VIIIc foi de 98,5%. A cesárea foi realizada em nove casos (69%), cuja anestesia foi do tipo raquidiana em sete casos. Como complicação do parto, um caso evoluiu com descolamento prematuro da placenta e foi realizada a cesárea. Um caso apresentou sangramento no primeiro pós-parto, necessitando reposição do fator VIII. Em dois casos foi realizada a reposição profilática do fator VIII antes da cesárea. A restrição do crescimento fetal ocorreu em cinco casos (38,5%). O peso dos RNs apresentou média de 2676 gramas e um caso (7,8%) apresentou Apgar de 1º minuto inferior a sete. CONCLUSÃO: O parto em gestantes com diagnóstico de doença de von Willebrand tem evolução favorável quando cuidados são tomados procurando oferecer assistência específica. O crescimento fetal deve ser monitorizado nessas gestantes.

OBJECTIVE: To study maternal complication associated to delivery and the puerperium period in pregnancies affected by von Willebrand's disease. METHODS: Chart data of all the pregnant women with diagnosis of von Willebrand disease were retrospectively reviewed. All cases with von Willebrand's disease that had given birth at this institution, between March 2001 and August 2007, were analyzed. The following variables were investigated: mode of delivery, hemorrhage complications during delivery and postpartum, maternal blood exams and perinatal results. Variables were studied descriptively, using absolute and relative frequencies, means, medians and standard deviations. RESULTS: 13 pregnancies of eight women with the disease were reviewed. During this sane period, there were 13,037 deliveries in the institution, resulting in an incidence of 0.1%. Six women (75%) were type 1 disease and, two (25%) were type 2. The last Factor VIIIc activity presented a mean value of 98.5%. A Cesarean section was performed in nine pregnancies, with epidural anesthesia in seven. Delivery complication occurred in two cases: one presented placental abruption and a Cesarean was performed. The other, presented postpartum hemorrhage in the first day and required reposition with factor VIII. Two cases received factor VIII before Cesarean section. Fetal growth restriction was detected in five pregnancies (38.5%). Mean birth weight was of 2676 grams and one case presented 1st minute Apgar score below seven. CONCLUSION: Delivery in patients with von Willebrand disease has a favorable evolution when specific assistance is provided. In these pregnancies,fetal growth should be monitored.
