PURPOSE: To evaluate the nuclear maturation stage and the presence of meiotic spindles of in vivo matured oocytes from infertile women undergoing stimulated cycles for intracytoplasmic sperm injection (ICSI) and compare intracytoplasmic sperm injection outcomes between oocytes in telophase I (TI) and metaphase II (MII), and the ones with and without visible meiotic spindle. METHODS: A prospective and controlled study with 106 infertile patients who underwent ovarian stimulation for intracytoplasmic sperm injection purposes. Patients aged 38 years or less, with basal follicle stimulating hormone (FSH) less than 10 mIU/mL and body mass index (BMI) less than 30 kg/m². Were included patients presenting any systemic diseases, any active infection, smokers or patients who had been using hormonal medications and hormonal and nonhormonal anti-inflammatory drugs for the past two months prior to the assisted reproduction procedure were excluded. The oocytes with the first polar body extruded (in vivo matured oocytes) were imaged by polarization microscopy immediately before intracytoplasmic sperm injection and characterized according to nuclear maturation stage (telophase I and metaphase II) and to the presence of a meiotic spindle. We analyzed the fertilization rates, cleavage, number of good quality embryos on the second day (D2) from oocytes on telophase I versus those in metaphase II, and metaphase II visible spindle versus non-visible ones. Data were analyzed comparatively by Fisher's exact test. The level of significance was set at 5% in all analyses (p<0.05). RESULTS: The meiotic spindles of 516 oocytes were imaged using polarization microscopy. From the 516 oocytes analyzed, seventeen were in telophase I (3.3%) and 499 (96.7%) in metaphase II. The oocytes injected in telophase I had significantly lower fertilization rates than those injected in metaphase II (53 and 78%, respectively) and produced no good quality embryos on day 2. When the oocytes with and without a visible meiotic spindle were compared, there was no significant difference in the intracytoplasmic sperm injection results. CONCLUSIONS: Oocytes injected in telophase I showed lower fertilization rates when compared to those in metaphase II. It is possible that the analysis of oocyte nuclear maturation by polarization microscopy can be used as a predictor of fertilization after intracytoplasmic sperm injection.

PURPOSE: To assess the prevalence of bacterial vaginosis and to compare the accuracy of testing pH and KOH with the Nugent gradient, the gold standard for the diagnosis of bacterial vaginosis (BV) in asymptomatic and symptomatic pregnant women at low risk. METHODS: We conducted a cross-sectional study on 321 pregnant women with gestational age between 14 and 26 weeks, 218 of them asymptomatic and 103 with vaginal complaints suggestive of bacterial vaginosis. All women were assessed by the criteria of Nugent and subjected to the measurement of vaginal pH and to the 10% KOH test. The Kappa coefficient was used to evaluate the methods in terms of diagnostic agreement. RESULTS: Most patients were adolescents (mean age 21.0±5.6 years), nulliparous and mulattos. The prevalence of bacterial vaginosis was 33.3% as estimated by the pH and KOH method and 35.5% by the Nugent method. Excellent agreement of the methods was found among asymptomatic pregnant women, with 72.5% of them showing negative results to both tests, which resulted in a high Kappa coefficient (k=0.82). The group of symptomatic women showed 49.5% positivity to both diagnostic methods, with excellent agreement (k=0.74). CONCLUSION: The prevalence of bacterial vaginosis determined by both the pH and KOH method and the Nugent score was high. The pH and KOH method can diagnose bacterial vaginosis as accurately as the Nugent criterion.

PURPOSE: To evaluate factors associated with morbidities among Brazilian women aged 40-65 years and with 11 or more years of schooling. METHODS: A secondary analysis of a cross-sectional population-based study was conducted, using an anonymous self-report questionnaire completed by 377 women. Were evaluated, with this instrument, some morbidities (hypertension, diabetes, insomnia and depression) and sociodemographic, behavioral, clinical and reproductive factors. The association between morbidities and independent variables was evaluated by the Χ2 test. Multiple logistic regression analysis with stepwise selection criteria was used to select the major factors associated with morbid conditions. RESULTS: In the multiple regression analysis, insomnia was associated with bad/fair self-perception of health (OR=2.3) and nervousness (OR=5.1). Depression was associated with bad/fair self-perception of health (OR=3.7) and bad/poor leisure (OR=2.8). Hypertension was associated with obesity (OR=3.1) and being in postmenopausal (OR=2.6). Diabetes was associated with age above 50 years (OR=3.9) and obesity (OR=12.5). CONCLUSIONS: The prevalence of morbidities was high and a worse self-perception of health and obesity were the main factors associated with morbidity.

PURPOSE: To evaluate the thickness of the lower uterine segment by transvaginal ultrasound in a group of non-pregnant women and to describe the morphologic findings in the scar of those submitted to cesarean section. METHODS: A retrospective study of 155 transvaginal ultrasound images obtained from premenopausal and non-pregnant women, conducted between January 2008 and November 2011. the subjects were divided into three groups: women who were never pregnant (Control Group I), women with previous vaginal deliveries (Control Group II) and women with previous cesarean section (Observation Group). We excluded women with a retroverted uterus, intrauterine device users, pregnant women and those with less than one year of tsince the last obstetrical event. The data were analyzed statistically with Statistica®, version 8.0 software. ANOVA and LSD were used to compare the groups regarding quantitative variables and the Student's t-test was used to compare the thickness of the anterior and posterior isthmus. The Spearman correlation coefficient was calculated to estimate the association between quantitative variables. P values <0.05 were considered statistically significant. RESULTS: There was significant difference between the thickness of the anterior and posterior isthmus only in the group of women with previous cesarean section. Comparing the groups two by two, no significant differences between the thickness of the anterior and posterior isthmus were observed in the Control Groups, but this difference was significant when we compared the Observation Group with each Control Group. In the Observation Group, no correlation was found between the thickness of the isthmus and the number of previous cesarean deliveries or the time elapsed since the last birth. A niche was found in the cesarean scar in 30.6% of the women in the Observation Group, 93% of whom complained of post-menstrual bleeding. CONCLUSION: The relationship between the thickness of the anterior and posterior wall of the lower uterine segment by transvaginal ultrasound is a suitable method for the evaluation of the uterine lower segment in women with previous cesarean sections.
