These pregnancies require more attention due to their worse outcomes than singleton pregnancies. Objective: To analyze the characteristics and perinatal outcomes of twin pregnancies at the Caxias do Sul General Hospital. Methods: This is a descriptive and retrospective study that included all births related to twin pregnancies between March 1998 and June 2018. Maternal and perinatal variables were analyzed. Descriptive analyses were carried out using measures of central tendency and dispersion for continuous variables (mean and standard deviation or median and interquartile range), according to a prior assessment of distribution using the Shapiro-Wilk test, and absolute (n) and relative (n%) frequencies for categorical variables. Results: 172 pairs of twins/21,972 births (0.8%) were identified. There was a high percentage of interpartum interval of less than 12 months, adherence and prenatal visits, body mass index, and need for neonatal intensive care. Stillbirth and neomortality rates were within acceptable parameters. Conclusion: The sample studied showed a percentage similar to that in the literature, a high rate of maternal and perinatal complications, characterizing it as a high-risk fetal pregnancy.展开更多

Because PPCM is associated with significant mortality, timely diagnosis and management are essential. Ventricular tachycardia (VT) is a major complication and contributor to sudden death. Available data on VT in patients with PPCM are limited. Aim: This case report demonstrates the clinical presentation, antenatal care, and management of labor and delivery in a patient with PPCM complicated by VT. Case report: 36-year old patient G4P3 presents at 27 weeks gestation to the emergency department complaining of chest tightness, palpitations, and profuse sweating. Peripartum cardiomyopathy was diagnosed after her last pregnancy a few years prior. Ventricular tachycardia was diagnosed at this visit and treated successfully. The remainder of the pregnancy was uneventful until she had another episode of ventricular tachycardia during labor. Treatment using antiarrhythmics (diltiazem, amiodarone, adenosine) highlights the importance of prompt intervention and the need for a range of therapeutic options. Results: This case demonstrated successful VT management during pregnancy and labor, emphasizing multidisciplinary collaboration, influencing maternal and fetal outcomes positively, providing insights into optimal care strategies. Conclusion: Peripartum cardiomyopathy complicated by ventricular tachycardia is a life-threatening combination. This case highlights the importance of timely diagnosis and management with combined care between cardiologists, maternal fetal medicine specialists and anesthesiologists to prevent morbidities and sudden maternal death.展开更多

Topic： Supplementation with omega-3 has been proposed to reduce the risk of preeclampsia, but the effects of this intervention are still uncertain. Method： A RCT （randomized controlled trial） had been conducted on 400 pregnant women between 12 and 16 weeks of gestation. Women were assigned randomly to either the control group or the study group. Achievements： Of the 400 women enrolled, 195 were randomly assigned to the study group and 205 to the control group. There was a significant difference between the study and the control groups in relation to the incidence ofpreeclampsia （0.5% and 5.5% respectively, P 〈 0.05）.展开更多
