Some studies have investigated the influence of hormonal deficits and menopausal status in muscle disorders of women. However, it has not been investigated the relationship of both climacteric symptoms and the perception of quality of life with physical performance.
To evaluate the correlation of menopausal symptoms and quality of life with physical performance in middle-aged women.
This cross-sectional study was performed from April to November 2013 in the municipality of Parnamirim, in the Brazilian state, Rio Grande do Norte. The sample was composed of 497 women aged 40-65 years. The Menopause Rating Scale (MRS) and the Utian Quality of Life (UQOL) questionnaire were used to evaluate menopausal symptoms and quality of life respectively. Measures of physical performance included handgrip strength, knee extensor and flexor strengths (using an isometric dynamometer), gait speed, and chair stand test. The correlation between menopausal symptoms and quality of life with physical performance was assessed by Pearson's correlation coefficient with significance set at p< 0.05 and a confidence interval of 95 %.
There was a significant negative correlation between handgrip strength and somatic MRS score (p= 0.002) and total MRS score (p= 0.03). There was a significant correlation between knee flexor strength and sit-to-stand time and all menopausal symptom areas (p< 0.05), except psychological symptoms. There was a positive correlation between physical performance of the knee flexors and quality of life items including occupational (p= 0.001), emotional (p= 0.005), and total UQOL (p= 0.01) , but a negative correlation with sit-to-stand time and all quality of life domains (p< 0.05).
A greater intensity of menopausal symptoms and worse quality of life were related with worse physical performance. Thus, preventive measures should be implemented to avoid adverse effects on physical performance at more advanced ages.

To verify sociodemographic factors associated with the occurrence of abortion in women of reproductive age, in areas covered by the Family Health Strategy (FHS), a program from the Brazilian Ministry of Health.
A cross-sectional study using household surveys of 350 women aged 15 to 49. The report of abortion was a variable indicator, and sociodemographic aspects were covariables. Prevalence ratio (PR) and respective 95% confidence intervals were used to estimate the magnitude of the associations.
There were associations among age, civil status, race/color, and religion; an increase in the prevalence of lower levels of education, age less than 20, and student status were protective factors.
The association between sociodemographic characteristics and the report of abortion is attributed to the fact that there is a lack at the FHS in the availability of fundamental healthcare services for young women; these findings call for action to guarantee the access to information about contraceptives and guidance to decrease the risk of unplanned pregnancies and abortions.

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.
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.
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.
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.
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.

betatrophin has been reported to boost β cell expansion in insulin resistant states. Pregnancy is a well-recognized physiological state of insulin resistance. Betatrophin levels in pregnant women and their relationships with metabolic variables remain to be elucidated.
A total of 49 pregnant women and 31 age-matched unpregnant women with normal glucose regulation (UP-NGR) were included. Among these subjects, according to results from 75 g oral glucose tolerance test (OGTT), 22 women were diagnosed as having gestational diabetes mellitus ( GDM ).
Our study found that pregnant women, regardless of their glucose regulation status, had remarkably higher triglycerides (TG), total cholesterol (TC), fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR) and homeostasis model assessment of β-cell function (HOMA-β). However, GDM patients had much lower HOMA-β compared with those of pregnant women with normal glucose regulation (P-NGR). Participants of the P-NGR group had almost 4 times higher levels of betatrophin than those of the UP-NGR group. Although betatrophin levels were lower in the GDM group than those of the P-NGR group, the difference did not reach statistical significance. Spearman correlation analysis showed that betatrophin levels were positively and significantly associated with total cholesterol, triglycerides, highdensity lipoprotein cholesterol (HDL-c), FINS and HOMA-β. However, adjustments of TC, TG and HDL-c eliminated the association between HOMA-β and betatrophin.
Pregnant women have significantly higher betatrophin levels in comparison to unpregnant women. Betatrophin levels are positively and significantly associated with β cell function and lipid levels. Furthermore, lipids may contribute to

To assess the prevalence of depressive symptoms and their association with social, psychological, behavioral and obstetric characteristics in pregnant women.
This is a cross-sectional study. The sample consisted of 375 pregnant women who attended prenatal clinics in two public maternity hospitals located in the city of Goiania, Brazil. To testify the depressive symptoms, we used the Hospital Anxiety and Depression Scale (HADS). A descriptive statistical analysis was performed using programs such as CDC EPI-INFO(tm), version 7.1.5, and Statistical Package for Social Sciences (IBM SPSS), version 21.0.
the patients had probable depressive symptoms (15.47%) and possible depressive symptoms (25.33%). The bivariate analysis showed a significant association among "depressive symptoms" and the following variables: "single or divorced" (prevalence ratio, PR = 2.08; 95% confidence interval, CI = 1.26 to 3.44); "physical activity during pregnancy" (PR = 3.96; 95%CI = 1.28 to 12.31); exposure to "psychological/emotional" violence (PR = 4.74; 95%CI = 2.94 to 7.64); "prior mental problem" (PR = 2.66; 95%CI =1.49 to 4.73) and "obstetric complications during pregnancy" (PR = 2.53; 95%CI = 1.55 to 4.13). The multivariate analysis confirmed the association of these depressive symptoms with the variables "suffered psychological/emotional violence" (odds ratio, OR = 5.821; 95%CI = 2.939 to 11.528); "physical activity during pregnancy" (OR = 3.885; 95%CI = 1.060 to 14.231); "obstetric complications during pregnancy" (OR = 2.442; 95%CI = 1.233 to 4.834) and "single or divorced" (OR = 2.943; 95%CI = 1.326 to 6.533).
the prevalence of depressive symptoms among pregnant women is of 15.47%, and emotional violence is the main factor associated with gestational depression.

Episiotomy is a controversial procedure, especially because the discussion that surrounds it has gone beyond the field of scientific debate, being adopted as an indicator of the "humanization of childbirth". The scientific literature indicates that episiotomy should not be performed routinely, but selectively.
To review the literature in order to assess whether the implementation of selective episiotomy protects against severe perineal lacerations, the indications for the procedure, and the best technique to perform it.
A literature search was performed in PubMed using the terms episiotomy or perineal lacerations, and the filter clinical trial. The articles concerning the risk of severe perineal lacerations with or without episiotomy, perineal protection, or episiotomy techniques were selected.
A total of 141 articles were identified, and 24 of them were included in the review. Out of the 13 studies that evaluated the risk of severe lacerations with and without episiotomy, 5 demonstrated a protective role of selective episiotomy, and 4 showed no significant differences between the groups. Three small studies confirmed the finding that episiotomy should be performed selectively and not routinely, and one study showed that midline episiotomy increased the risk of severe lacerations. The most cited indications were primiparity, fetal weight greater than 4 kg, prolonged second stage, operative delivery, and shoulder dystocia. As for the surgical technique, episiotomies performed with wider angles (> 40°) and earlier in the second stage (before "crowning ") appeared to be more protective.
Selective episiotomy decreases the risk of severe lacerations when compared with the non-performance or the performance of routine episiotomy. The use of a proper surgical technique is fundamental to obtain better results, especially in relation to the angle of incision, the distance from the vaginal introitus, and the correct timing for performing the procedure. Not performing the episiotomy when indicated or not applying the correct technique may increase the risk of severe perineal lacerations.

Pathophysiological mechanisms of peripartum cardiomyopathy are not yet completely defined, although there is a strong association with various factors that are already known, including pre-eclampsia. Peripartum cardiomyopathy treatment follows the same recommendations as heart failure with systolic dysfunction. Clinical and experimental studies suggest that products of prolactin degradation can induce this cardiomyopathy. The pharmacological suppression of prolactin production by D2 dopamine receptor agonists bromocriptine and cabergoline has demonstrated satisfactory results in the therapeutic response to the treatment. Here we present a case of an adolescent patient in her first gestation with peripartum cardiomyopathy that evolved to the normalized left ventricular function after cabergoline administration, which was used as an adjuvant in cardiac dysfunction treatment. Subsequently, despite a short interval between pregnancies, the patient exhibited satisfactory progress throughout the entire gestation or puerperium in a new pregnancy without any cardiac alterations. Dopamine agonists that are orally used and are affordable in most tertiary centers, particularly in developing countries, should be considered when treating peripartum cardiomyopathy cases.
