To translate into Portuguese, culturally adapt and validate the Uterine Fibroid Symptom - Quality of Life (UFS-QoL) questionnaire for Brazilian women with uterine leiomyoma.
Initially, the UFS-QoL questionnaire was translated into Brazilian Portuguese in accordance with international standards, with subsequent cultural, structural, conceptual and semantic adaptations, so that patients were able to properly answer the questionnaire. Fifty patients with uterine leiomyoma and 19 patients without the disease, confirmed by abdominal pelvic examination and/or transvaginal ultrasound, were selected at the outpatient clinics of the Department of Gynecology of the Universidade Federal de São Paulo (Unifesp). The UFS-QoL questionnaire was administered to all women twice on the same day, with two different interviewers, with an interval of 15 minutes between interviews. After 15 days, the questionnaire was readministered by the first interviewer. Reliability (internal consistency and test-retest), construct and discriminative validity were tested to ratify the questionnaire.
The reliability of the instrument was assessed by Cronbach’s α coefficient with an overall result of 0.97, indicating high reliability. The survey results showed a high correlation (p= 0.94; p 0.001).
The UFS-QoL questionnaire was successfully adapted to the Brazilian Portuguese language and Brazilian culture, showing reliability and validity.

Triple-negative breast carcinomas (TNBCs) represent a heterogeneous group of neoplasias, even though they generally exhibit a clinically more aggressive phenotype, and are more prevalent in young women. To date, targeted therapies for this group of tumors have not been defined. The aim of this study was to evaluate the frequency of the apocrine subtype in TBNCs from premenopausal patients as defined by the immunohistochemical expression of the androgen receptor (AR) and its association with: histological type; tumor grade; proliferative activity; epidermal growth factor receptor (EGFR) expression; and a basal-like phenotype.
A total of 118 tumor samples from patients aged 45 years or younger were selected and reviewed according to histological type and grade. Ki-67 expression was also evaluated. Immunohistochemical expression of the AR, basal cytokeratin ⅚, and EGFR expression were analyzed in tissue microarrays. The apocrine subset was defined by AR-positive expression. The basal-like phenotype was characterized by cytokeratin ⅚ and/or EGFR expression.
An apocrine profile was identified in 6/118 (5.1%) cases. This subset of cases also exhibited a lower rate of Ki-67 expression (17.5% versus 70.0%, p= 0.02), and a trend toward a lower histological grade (66.7% versus 27.9%, p= 0.06).
The apocrine subtype of TNBCs is rare among premenopausal women, and it tends to present as carcinomas of lower grade and lower proliferative activity, suggesting a less aggressive biological phenotype.

To evaluate the accuracy of transvaginal ultrasonography, hysteroscopy and uterine curettage in the diagnosis of endometrial polyp, submucous myoma and endometrial hyperplasia, using as gold standard the histopathological analysis of biopsy samples obtained during hysteroscopy or uterine curettage.
Cross-sectional study performed at the Hospital Universitário de Brasília (HUB). Data were obtained from the charts of patients submitted to hysteroscopy or uterine curettage in the period from July 2007 to July 2012.
One-hundred and ninety-one patients were evaluated, 134 of whom underwent hysteroscopy, and 57, uterine curettage. Hysteroscopy revealed a diagnostic accuracy higher than 90% for all the diseases evaluated, while transvaginal ultrasonography showed an accuracy of 65.9% for polyps, 78.1% for myoma and 63.2% for endometrial hyperplasia. Within the 57 patients submitted to uterine curettage, there was an accuracy of 56% for polyps and 54.6% for endometrial hyperplasia.
Ideally, after initial investigation with transvaginal ultrasonography, guided biopsy of the lesion should be performed by hysteroscopy, whenever necessary, in order to improve the diagnostic accuracy and subsequent clinical management.

To identifying spatial patterns in the distribution of perinatal mortality in the state of São Paulo from 2003 to 2012.
An ecological and exploratory study with data on perinatal mortality rates of every thousand live births, which were registered on the digital database containing 645 municipalities in the state of São Paulo within the periods of 2003 to 2007 and 2008 to 2012. The spatial analysis provided Moran’s index (MI) and thematic maps of rates, and the Moran maps of both periods were drawn. The average rates were compared by Student’s t test. The TerraView 4.2.2 software (INPE, S. José dos Campos, Brazil) was also used.
There were 49,485 perinatal deaths during the first period, at a rate of 17.90 deaths/1,000 live births (standard deviation [SD] = 7.0; MI = 0.14; p = 0.01), and 44,582 perinatal deaths during the second period, at a rate of 16.40 deaths/1,000 live births (SD = 11.14; MI = 0.04; p = 0.03). These rates are statistically different (p < 0.01). There was a decrease in these rates in 413 municipalities when comparing the two periods. The Moran map has identified 35 municipalities that require special attention, which are located in the Eastern, Southwestern, Western and Northwestern regions of São Paulo state.
The study provides municipal managers with subsidies so they can minimize these rates by implementing public policies and taking better care of pregnant women and newborns.

To identify which methods used in the assessment of the ovarian reserve are exclusive or complementary to identify the best response to follicle development.
Retrospective cohort study, involving patients undergoing assisted reproduction treatment at the Instituto de Medicina Reprodutiva e Fetal, from April 2009 to July 2014. Age, biochemical tests, and ultrasound were assessed. The data were analyzed to predict the follicular development and the relation between them, using, for statistical analysis, Statistical Package for Social Sciences software.
Out of the 293 couples included, 50.2% presented infertility by ovarian factor. Considering the age as the main variable, a significant negative correlation with the volume of both ovaries was observed (right ovary, r = 0.21; left ovary, r =0.22; both p< 0.0001), and with the antral follicle count (right ovary, r =0.38; left ovary, r =0.47; both p< 0.0001). Considering the antral follicle count as the main variable, a significant positive correlation with the total recruited oocytes was observed. When we correlated the antral follicle count with the recruited follicles larger than 18 mm, we observed that, with a cutoff of 12 antral follicles, there is a positive predictive value of 99%, and an area under the ROC curve of 0.76.
We concluded from our study that age and antral follicle count are effective predictors of ovarian response in cycles of assisted reproduction. The ovarian volume, as well as the anti-Müllerian hormone dosage, seem to be adequate markers of the ovarian reserve.

Identify factors associated with infant mortality by a hierarchical model based on socioeconomic, health care, obstetric and biological determinants in a northeastern Brazilian capital.
Observational, retrospective cohort study based on secondary data of births and deaths of infants of mothers living in the city of Teresina.
Based on the distal level of determination of infant mortality, the characteristics that remained statistically significant were maternal age, maternal education and maternal occupation (p< 0.001). In the intermediate level, all variables were statistically significant, particularly the type of pregnancy and delivery (p< 0.001). The gender of the baby was the proximal level feature that had no significant association with the outcome, while the other variables of this level had association (p< 0.001).
This study evidenced that, in addition to biological factors, socioeconomic status and maternal and child health care are important to determine infant mortality.

Infertility has a high prevalence in the general population, affecting 5 to 15% of couples in reproductive age. The assisted reproduction techniques ( ART ) include in vitro manipulation of gametes and embryos and are an important treatment indicated to these couples. It is well accepted that the implantation rate is positively influenced by the morphology of transferred embryos. However, we question if, apart from the assessment of embryo morphology, the number of produced embryos per cycle is also related to pregnancy rates in the first fresh transfer cycle.
To evaluate the clinical pregnancy rate according to the number of formed embryos and the transfer of top quality embryos ( TQEs ).
In a retrospective cohort study, between January 2011 and December 2012 , we evaluated women who underwent intracytoplasmic sperm injection (ICSI), aged < 40 years, andwith at least 1 formed embryo fresh transferred in cleavagestage. These women were stratified into 3 groups according to the number of formed embryos (1 embryo, 2-3 and ≥ 4 embryos). Each group was divided into 2 subgroups according to the presence or not of at least 1 transferred TQE (1 with TQE; 1 without TQE; 2-3 with TQE, 2-3 without TQE; ≥4with TQE; ≥4withoutTQE). The clinicalpregnancy rateswerecomparedineach subgroup based on the presence or absence of at least one transferred TQE.
During the study period, 636 women had at least one embryo to be transferred in thefirst fresh cycle (17.8% had 1 formed embryo [32.7% with TQEversus 67.3% without TQE], 42.1% of women had 2-3 formed embryos [55.6% with TQE versus 44.4% without TQE], and 40.1%ofpatientshad ≥4 formedembryos[73.7%withTQEversus26.3%withoutTQE]).The clinical pregnancy rate was significantly higher in the subgroup with ≥4 formed embryos with at least 1 transfered TQE (45.2%) compared with the subgroup without TQE (28.4%).
Having at least two available embryos and at least one TQE for embryo transfer are predictors of the pregnancy rates.

To evaluate the anatomic and functional results of a laparoscopic modified Vecchietti technique for the creation of a neovagina in patients with congenital vaginal aplasia.
Retrospective study of nine patients with congenital vaginal aplasia submitted to the laparoscopic Vecchietti procedure, in our department, between 2006 and 2013. The anatomical results were evaluated by assessing the length, width and epithelialization of the neovagina at the postoperative visits. The functional outcome was evaluated using the Rosen Female Sexual Function Index (FSFI) questionnaire and comparing the patients' results to those of a control group of 20 healthy women. The statistical analysis was performed using SPSS Statistics version 19.0 (IBM, Armonk, NY, USA), Student t-test, Mann-Whitney U test and Fisher exact test.
The condition underlying the vaginal aplasia was Mayer-Rokitansky-KüsterHauser syndrome in eight cases, and androgen insensitivity syndrome in one case. The average preoperative vaginal length was 2.9 cm. At surgery, the mean age of the patients was 22.2 years. The surgery was performed successfully in all patients and no intra or postoperative complications were recorded. At the first postoperative visit (6 to 8 weeks after surgery), the mean vaginal length was 8.1 cm. In all cases, the neovagina was epithelialized and had an appropriate width. The mean FSFI total and single domain scores did not differ significantly from those of the control group: 27.5 vs. 30.6 ( total); 4.0 vs. 4.2 (desire); 4.4 vs. 5.2 (arousal); 5.2 vs. 5.3 (lubrication); 4.2 vs. 5.0 ( orgasm); 5.3 vs. 5.5 (satisfaction) and 4.4 vs. 5.4 ( comfort ).
This modified laparoscopic Vecchietti technique is a simple, safe and effective procedure, which allows patients with congenital vaginal aplasia to have a satisfactory sexual activity, comparable to that of normal controls.
