To evaluate the risk factors for morbidity and mortality in an obstetric intensive care unit at a university hospital.
Observational cross-sectional study with 492 pregnant/puerperal women. Patients were admitted to the obstetric intensive care unit over a period of one year, being informed about the proposals of the study and a questionnaire was applied. The analysis was performed using Microsoft Excel 2013 and GraphPad Prism 6. To evaluate risk factors, χ2 tests were used.
The main risk factors to near miss were: non-white race (OR=2.5; PR=2.3); marital status (married women) (OR=7.9; PR=7.1), schooling (primary) (OR=3.1; PR=2.8), being from the countryside (OR=4.6; PR=4.0), low income (OR=70; PR=5.5), gestational hypertensive disorders (OR=16.3; PR=13.2), receiving prenatal care (OR=5.0; PR=4.254) and C-section before labor (OR=39.2; PR=31.2).
The prevalence of near miss was associated with socioeconomic/clinical factors and care issues, revealing the importance of interventions to improve these indicators. Additionally, we suggest a better curriculum insertion of this subject in the discipline of the medical course due to the importance of avoiding the near miss using adequate medical education. The importance of correct prenatal care is emphasized in order to identify potential risks, to provide nutritional support to pregnant women, to treat potential diseases and to establish a maternal immunization program, as well as providing better care regarding the clinical features of the patients, in order to reduce obstetrical and neonatal risk.

To evaluate the factors associated with anemia among pregnant women receiving public health care in a capital city in Northeastern Brazil.
This was a cross-sectional study conducted on a sample of 428 patients obtained on the basis of the estimated prevalence of anemia during pregnancy (50%), a 95% confidence interval (95%CI), an error of 5% and a sample loss of 20%. Pregnant women who lived in the city and were served by the municipal public health network were considered to be eligible for the study. Socioeconomic, lifestyle, clinical and anthropometric data and dietary iron intake were obtained, and capillary hemoglobin was determined. Anemia was identified as a hemoglobin level <11 g/dL, and its association with risk factors was tested using multivariate Poisson regression analysis, with the results expressed as the Prevalence Ratio (PR) and 95%CI.
The prevalence of anemia was 28.3% and was higher among women with more members in the household (PR=1.49; 95%CI 1.01-2.22; p=0.046) and those living with food insecurity (PR=1.43; 95%CI 1.00-2.04; p=0.047).
The prevalence of anemia among pregnant women receiving care from the public health system of the city is a moderate public health problem, requiring the planning of effective measures for its control.

To assess the chemotactic activity and phagocytic response of neutrophilic polymorphonuclear leukocytes among women in the first five days postpartum.
A prospective, cross-sectional clinical-laboratory study was conducted. Data of 31 postpartum women during the first five days after vaginal delivery were compared with those of 24 healthy non-pregnant non-postpartum women matched for age. The inclusion criteria were postpartum, clinically and obstetrically healthy women; vaginal delivery, singleton pregnancy carried to term; non-hypertensive, hyperglycemic, allergic, malnourished or with autoimmune or neoplastic diseases; not having received vaccines or blood products in the last three months. The Control Group was chosen according to the same inclusion criteria but involving non-pregnant non-postpartum women. The chemotactic activity of neutrophilic polymorphonuclear leukocytes was assessed by determining the distance from directed migration to bacterial lipopolysaccharide, in three Boyden chamber assays. The phagocytic response was identified by assessing the Zymosan particles' ingestion in three assays carried out in Leighton tubes. The Student's t- test was used in the statistical analysis, adopting a 5% level of significance.
The chemotactic activity of neutrophilic polymorphonuclear leukocytes from postpartum women in the presence of homologous (73.2±6.9) and autologous (78.6±13.9) sera showed a significant increase compared to the values observed in the Control Group (64.1±4.1 and 66.6±5.4). Both chemotactic response and phagocytosis ingestion phase of neutrophilic polymorphonuclear leukocytes were significantly increased (p<0.05) in postpartum women compared to healthy non-pregnant and non-postpartum women.
There was an increase in the chemotactic activity and phagocytic response of neutrophilic polymorphonuclear leukocytes during the first five days after vaginal delivery in women.

To investigate the frequencies of polymorphic allele and genotypes for the LT-α gene, position +252 (rs909253), in Brazilian women with preeclampsia.
This is a case-control study, in which 30 women with preeclampsia, classified according to the criteria of the National High Blood Pressure Education Program, and 115 women in the control group, with at least two healthy pregnancies, were selected. Peripheral blood was collected, and DNA was extracted, followed by genotyping, using specific primers and restriction analysis. The genotypes obtained were AA, AG and GG. Statistical analysis was performed using the χ2 association test. The Hardy-Weinberg Equilibrium was tested using the Haploview Program.
The results showed no association between genotypes and preeclampsia development (χ2=2.0; p=0.4). When the AG and GG genotypes were grouped according to allele G presence or absence (genotype AA), the data showed that the presence of allele G was not significantly different between cases (women with preeclampsia) and controls (χ2=0.0; p=1.0). The LT-α gene polymorphism, position +252 (rs909253), seems not to be an important candidate for the development of preeclampsia. Other inflammatory genes should be researched, and studies involving gene-environment interactions should be performed, in order to reach a better understanding of the etiology of the preeclampsia.

To translate, to adapt and to validate the Utian Quality of Life (UQOL) for the Brazilian population.
Women in the climacteric phase, residents in the city of Natal, Rio Grande do Norte, located in the Brazilian Northeast, were randomly selected. UQOL and SF-36 questionnaires were used, and the translation from English to Portuguese was made by three teachers, while the adaptation stage of the translated version was made by applying the questionnaire to 35 women, which could mark the answer choice "I did not understand the question"; reproducibility measurements (test-retest) and construct validity were used to validate, following international methodological standards.
The Brazilian version was fully recognized by the target population, which was comprised of 151 women, as no question showed a percentage of "non-understanding" equal to or greater than 20%. The results for intra and interobserver reproducibility demonstrated significant agreement on all the questionnaire items. This version showed consistency above the required criteria (>70), demonstrating its accuracy, while the construct validity was obtained by statistically significant correlations between the domains occupation, health and emotional of UQOL and the SF-36 domains. The Cronbach's alpha coefficient for the whole instrument was 0.82, representing good accuracy. Item-total correlation analysis showed the scale homogeneity
From the steps taken, the UQOL questionnaire was translated and adapted for its use in Brazil, with high reproducibility and validity. Thus, it can be included and used in Brazilian studies that aim at evaluating the quality of life of women during the peri- and postmenopausal.

Takotsubo cardiomyopathy is characterized by acute and transient dysfunction of the apical segment of the left ventricle usually after an intense physical or emotional stress, mimicking an acute coronary syndrome. Because this is a rare syndrome, the differential diagnosis is particularly important and a high level of suspicion is essential. Obstetricians should be aware to diagnose and deal with this unexpected event. Treatment is essentially supportive, with spontaneous and complete reversal of the changes within days or weeks. The occurrence of complications may dictate a less benign prognosis. We report a case of Takotsubo cardiomyopathy in a 39-year-old woman who underwent Cesarean delivery. She presented with bradycardia, chest pain and pulmonary edema immediately after the delivery. Her echocardiography showed and apical ballooning. Cardiac biomarkers and electrocardiogram were altered and echocardiogram showed severe left ventricular dysfunction with hypokinesia of the anterior wall. Coronary angiography excluded obstructive coronary artery disease.

In order to increase the success rate of in vitro fertilization cycles, several studies have focused on the identification of the embryo with higher implantation potential. Despite recent advances in the reproductive medicine, based on the OMICs technology, routinely applicable methodologies are still needed. Thus, in most fertilization centers embryo selection for transfer is still based on morphological parameters evaluated under light microscopy. Several morphological parameters may be evaluated, ranging from the pronuclear to blastocyst stage. In general, despite the day of transfer, some criteria are suggested to present a predictive value for embryo viability when analyzed independently or combined. However, the subjectivity of morphological evaluation, as well as the wide diversity of embryo classification systems used by different fertilization centers shows contrasting results, making the implementation of a consensus regarding different morphological criteria and their predictive value a difficult task. The optimization of embryo selection represents a large potential to increase treatment success rates, allowing the transfer of a reduced number of embryos and inimizing the risks of multiple pregnancy.
