title: Spatial distribution of pregnancy in adolescence and associations with socioeconomic and social responsibility indicators: State of Minas Gerais, Southeast of Brazil

description: PURPOSE: To describe associations between pregnancy rates in adolescence and socioeconomic and social responsibility indicators in the municipalities of the State of Minas Gerais, Southeast of Brazil, in the year of 2010.METHODS: Ecological study using data from the Brazilian Live Birth Information System (SINASC). The percentage of live births to adolescent mothers (LBAM) for each municipality was calculated based on the quotient between number of born alive infants of mothers aged 10-19 years old and total number of live births in the year of 2010. Fully Bayesian models were used to obtain the percentages of LBAM adjusted for spatial effects and to assess possible associations with socioeconomic and social responsibility indicators.RESULTS: The crude percentage of LBAM for the total number of live births in the municipalities of Minas Gerais in 2010 ranged from 0 to 46.4%, with median percentage being 19.6% and the first and third quartiles being 15.6 and 23.1%, respectively. This study has demonstrated a close relationship between adolescent pregnancy and socioeconomic indicators. LBAM percentages were found to be higher in municipalities with low population density, low human development index and other low development indicators.CONCLUSION: The strong relationship between LBAM percentages and socioeconomic indicators suggests that adolescent pregnancy is more a social than a biological problem. Therefore, programs and actions should go beyond sexual education and information on preventive health methods.

title: Estimation of Fetal Weight during Labor: Still a Challenge

description: Objective To evaluate the accuracy of fetal weight prediction by ultrasonography labor employing a formula including the linear measurements of femur length (FL) and mid-thigh soft-tissue thickness (STT). Methods We conducted a prospective study involving singleton uncomplicated term pregnancies within 48 hours of delivery. Only pregnancies with a cephalic fetus admitted in the labor ward for elective cesarean section, induction of labor or spontaneous labor were included. We excluded all non-Caucasian women, the ones previously diagnosed with gestational diabetes and the ones with evidence of ruptured membranes. Fetal weight estimates were calculated using a previously proposed formula [estimated fetal weight = [1] 1687.47 + (54.1 x FL) + (76.68 x STT). The relationship between actual birth weight and estimated fetal weight was analyzed using Pearson's correlation. The formula's performance was assessed by calculating the signed and absolute errors. Mean weight difference and signed percentage error were calculated for birth weight divided into three subgroups: &lt; 3000 g; 3000-4000g; and &gt; 4000 g. Results We included for analysis 145 cases and found a significant, yet low, linear relationship between birth weight and estimated fetal weight (p &lt; 0.001; R2 = 0.197) with an absolute mean error of 10.6%. The lowest mean percentage error (0.3%) corresponded to the subgroup with birth weight between 3000 g and 4000 g. Conclusions This study demonstrates a poor correlation between actual birth weight and the estimated fetal weight using a formula based on femur length and mid-thigh soft-tissue thickness, both linear parameters. Although avoidance of circumferential ultrasound measurements might prove to be beneficial, it is still yet to be found a fetal estimation formula that can be both accurate and simple to perform.

title: EZH2 Protein Expression and Tumor Response to Neoadjuvant Chemotherapy in Locally Advanced Breast Cancer

description: Abstract Introduction Neoadjuvant chemotherapy (NAC) is the standard treatment for locally advanced breast cancer. However, some tumors will not respond to this treatment due to histological and molecular features. The protein EZH2 (enhancer of zest homolog 2) is a histone methyltransferase that is correlated with poorly differentiated breast carcinomas and aggressive tumor behavior. Purpose The present study evaluated the association between EZH2 expression and response to NAC, and its correlation with HER2 overexpression, estrogen and progesterone receptors (ER, PR) and Ki-67 proliferation index. Methods A total of 60 patients with locally advanced breast cancer treated with NAC were selected for this study. Twenty-three paraffin blocks had not enough material for tissue resection, and were not evaluated. A tissue microarray based in immunohistochemistry (IHC) analysis of EZH2 was performed for the remaining 37 specimens. Patients were divided into two groups based on response to NAC. Results EZH2 expression was significantly associated with markers of poor prognosis such as ER negativity (p = 0.001), PR negativity (p = 0.042) and high Ki-67 proliferation index (p = 0.002). High EZH2 expression was not correlated with the response to NAC. Conclusions Our data suggested that EZH2 protein expression may not correlate with the clinical response to NAC. Other studies with more patients are needed to confirm this observation.

title: Electronic Medical Record for Prenatal Care of Diabetic Women

description: Objective To present and validate a multifunctional electronic medical record (EMR) for outpatient care to women with endocrine disorders in pregnancy and to compare health information data fill rate to conventional medical records. Methods We developed an EMR named Ambulatory of Endocrine Diseases in Pregnancy (AMBEG) for systematic registration of health information The AMBEG was used for obstetric and endocrine care in a sample of pregnant women admitted to the maternity reference in high-risk pregnancies in Bahia from January 2010 to December 2013. We randomly selected 100 patients accompanied with AMBEG and 100 patients monitored with conventional consultation and compared the health information data fill rate of the electronic consultation to that performed using conventional medical records. Results 1461 consultations were held, of which 253, 963 and 245 were first, follow-up and puerperium consultations, respectively. Most patients were pregnant women with diabetes (77.2%) and 60.1% were women with pre-gestational diabetes. The AMBEG satisfactorily replaced the conventional medical record. The percentage of registered information was significantly higher in the AMBEG: clinical symptoms (87% versus 100, p &lt; 0.01), uterine height (89 versus 75%, p = 0.01), total weight gain (91 versus 40%, p &lt; 0.01) and specific diabetes data (diet, insulin regimen, glycemic control and management of hypoglycemia) revealed a significant difference (p &lt; 0.01). The ability to export data to worksheets greatly facilitated and accelerated the statistical analysis of the data. Conclusions AMBEG is a useful tool in clinical care for women with endocrine diseases during pregnancy. The fill rate of clinical information was superior to that registered in conventional medical records.

title: Cultural Adaptation of the Patient Satisfaction Questionnaire and Validation of Its Use in the Portuguese Language for Women with Chronic Pelvic Pain

description: Abstract Objectives to translate and adapt the Patient Satisfaction Questionnaire (PSQ) to Portuguese and to assess its psychometric properties based on internal consistency, test-retest, factor analysis and divergent and convergent construct validities. Methods The study involved 218 participants and was approved by the local Research Ethics Committee. All participants gave written informed consent and their anonymity was ensured. The instrument was translated and culturally adapted for use in the Portuguese language. The internal consistency and factorial analysis were assessed by patients and physicians. Convergent and divergent validities were also assessed specifically for the patient group, as well as test-retest reliability. The Portuguese versions of the Patient Health Questionnaire (PHQ-9) and State-Trait Anxiety Inventory (STAI) were used for the analysis of the convergent validity. In addition, we applied a questionnaire of clinical and demographic data for the analysis of the divergent validity. Results The adapted version of the PSQ showed good Cronbach’s α and test-retest values, and the results of the convergent construct validity between the PSQ and the PHQ-9 (r = 0.34; p = 0.02) and the STAI (r = 0.47; p = 0.001) were negative, significant and moderate correlations. Divergent validity showed significant correlations only with race and education. The Brazilian Portuguese versionof the PSQ proved to be a valid and reliable instrument, with psychometric properties suitable for the assessment of satisfaction among patients with chronic pelvic pain and their physicians in Brazil. The questionnairemay allow the homogenization of reports on this topic in the international literature.

title: Early Experience of Robotic Hysterectomy for Treatment of Benign Uterine Disease

description: Abstract Objectives To demonstrate the initial experience of robotic hysterectomy to treat benign uterine disease at a university hospital in Brazil. Methods A cross-sectional study was conducted to review data from the first twenty patients undergoing robotic hysterectomy at our hospital. The surgeries were performed from November 2013 to August 2014, all of them by the same surgeon. The patients were reviewed for preoperative characteristics, including age, body mass index (BMI), indications for the hysterectomy and previous surgeries. Data of operative times, complications, postoperative pain and length of hospital stay were also collected. Results The total operating room time was 252.9 minutes, while the operative time was 180.7 minutes and the console time was 136.6 minutes. Docking time was 4.2 minutes, and the average undocking time was 1.9 minutes. There was a strong correlation between the operative time and the patient's BMI (r = 0.670 ; p = 0.001). The console time had significant correlation with the uterine weight and the patient's BMI (r = 0.468; p = 0.037). A learning curve was observed during docking and undocking times. Conclusion Despite its high cost, the robotic surgery is gaining more space in gynecological surgery. By the results obtained in our hospital, this surgical proposal proved to be feasible and safe. Our initial experience demonstrated a learning curve in some ways.

title: Accuracy of Transvaginal Ultrasonography, Hysteroscopy and Uterine Curettage in Evaluating Endometrial Pathologies

description: Abstract Objective 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. Methods 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. Results 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. Conclusion 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.

title: Depression in Women with Recurrent Miscarriages - an Exploratory Study

description: ABSTRACT Objective: To assess depression, domestic violence and the use of substances in women with recurrent miscarriages. Methods: The Abuse Assessment Screen (AAS), the Edinburgh Postnatal Depression Scale (EPDS) and the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) were used to assess violence, depression and the use of substances among women with recurrent miscarriages. The population corresponded to patients receiv-ing prenatal care from June to August 2014. Multiple logistic regression was used to assess the multivariable relationship between depression and sociodemographic, psychosocial and medical characteristics (p &lt; 0,10). Results: The prevalence of depression was of 41.3% (95% confidence interval [CI] 1/4 28.3-55.7%). One third of the pregnant women (32.6%) reported emotional or physical violence, and 13% were classified as abusing or addicted to tobacco according to ASSIST. History of psychiatric diseases was associated with depression (p 1/4 0.005). Violence during life demonstrated a modest association (p 1/4 0.073) with depression, as well as the number of miscarriages (p 1/4 0.071). Conclusion: Depression is a frequent disease among pregnant women with recurrent miscarriages. The results of this investigation suggest that a systematic assessment of depression and its associated conditions, such as domestic violence and the use of substances, should be part of the prenatal follow-up visits for women with recurrent miscarriages.
