To investigate the clinicopathological significance and prognosis of the expression of the anterior gradient 3 (AGR3) protein in women with breast cancer.
The PubMed, CINAHL, EMBASE, Scopus, and Web of Science databases were searched for studies published in English and without restrictions regarding the year of publication. The search terms were: breast cancer AND anterior gradient 3 OR AGR3 expression.
We included observational or interventional studies, studies on AGR3 protein expression by immunohistochemistry, and studies on invasive breast cancer. Case reports, studies with animals, and reviews were excluded. In total, 4 studies were included, containing 713 cases of breast cancer.
Data were extracted on clinicopathological characteristics and survival. A meta-analysis of the prevalence of AGR3 expression was performed according to the clinicopathological characteristics, hazard ratios (HRs), and overall survival and disease-free survival.
The expression of AGR3 was found in 62% of the cases, and it was associated with histological grade II, positivity of estrogen and progesterone receptors, low expression of ki67, recurrence or distant metastasis, and lumen subtypes. In patients with low and intermediate histological grades, AGR3 expression was associated with worse overall survival (HR: 2.39; 95% confidence interval [95%CI]: 0.628–4.159; p = 0.008) and worse disease-free survival (HR: 3.856; 95%CI: 1.026–6.686; p = 0.008).
The AGR3 protein may be a biomarker for the early detection of breast cancer and predict prognosis in luminal subtypes. In addition, in patients with low and intermediate histological grades, AGR3 protein expression may indicate an unfavorable prognosis in relation to survival.

To evaluate the frequency of structural congenital anomalies (CAs) in the midwest of Brazil and its association with maternal risk factors.
This was a prospective, observational, case-control study based on a hospital population. Pregnant women attended at a fetal medicine service in Brazil were analyzed in the period from October 2014 to February 2016.A total of 357 pregnant women were included, 223 of whom had fetuses with structural anomalies (group case), and 134 of whom had structurally normal fetuses (control group). The clinical history was made previous to prenatal consultation, and the diagnosis of the structural CA was performed through ultrasound.
A frequency of 64.27% (n = 223) of pregnant women with fetuses with structural anomalies was observed. The most frequent structural CAs were those of the central nervous system (30.94%), followed by anomalies of the genitourinary system (23.80%), and, finally, by multiple CAs (16.60%). The background of previous children with CAs (odds ratio [OR]: 3.85; p = 0.022), family history (OR: 6.03; p = < 0.001), and consanguinity between the progenitors (OR: 4.43; p = 0.034) influenced the occurrence of structural CA.
The most frequent CAs are those of the central nervous system, followed by those of the genitourinary system, and then multiple anomalies. The maternal risk factors that may have influenced the occurrence of structural CA were previous children with CA, family history, and consanguinity among the parents.

To evaluate and compare the prevalence of structural congenital anomalies (CAs) according to maternal body mass index (BMI).
The present cross-sectional study involved pregnant women with fetuses diagnosed with structural CAs through morphological ultrasonography between November 2014 and January 2016. The nutritional status of the pregnant women was classified according to the gross value of the body mass index. The pregnant women were categorized into four groups: low weight, adequate weight, overweight, and obesity. Statistical analysis was performed using Stata/SE version 12.0 (Stata Corporation, College Station, TX), with values of p ≤ 0.05 considered statistically significant.
A total of 223 pregnant women had fetuses diagnosed with CAs. The prevalence of structural CAs in pregnant women with lowweight was of 20.18%, of 43.50% in pregnant women with adequate weight, of 22.87% in pregnant women with overweight, and of 13.45% in pregnant women with obesity. The prevalence of central nervous system (CNS) anomalies and of genitourinary systemanomalieswas high for the four groups of pregnant women. A positive association was observed between multiple anomalies in pregnant women with adequate weight (prevalence ratio [PR] = 1.65; p ≤ 0.004) and between anomalies of the lymphatic system in obese pregnant women (PR = 4.04, p ≤ 0.000).
The prevalence of CNS and genitourinary systemanomalies was high in all of the BMI categories. Obese pregnancies were associated with lymphatic system anomalies. Therefore, screening and identification of the risk factors for CAs are important, regardless of the maternal BMI. Our findings reinforce the importance of discussing with pregnant women maternal nutrition and its effect on fetal development and on neonatal outcome.

To evaluate the perception of health professionals involved in the labor process and theassistanceto normal delivery, comparing two hospitals in the cityof Goiânia, Brazil, regarding the perception of theseprofessionals when they are performing the routines and practices recommended by the World Health Organization (WHO).
This is an analytical comparative study with a quantitative approach, performed in two public hospitals in the city of Goiânia, in the state of Goiás, Brazil. The study included 86 professionals working in assistance to immediate labor in two hospitals. A questionnaire containing 40 questions was applied. The questionnaire related to the Program for the Humanization of Prenatal and Childbirth Care (PHPN, in the Portuguese acronym) of the Brazilian Ministry of Health, the presence of a companion, and the procedures performed. For the data analysis, we used the chisquare and Fisher’s exact tests.
Most of the professionals claimed to know about the PHPN proposed by Brazilian Ministry of Health in the two hospitals. With regard to good practices, most professionals said that they are performed in maternity ward 2, while on maternity 1, although many of them are present, there are still many unnecessary interventions.
When comparing the two maternity hospitals, maternity 2, which was created as a routine humanization model, manages to better adhere to the WHO recommendations. In maternity 1, there was a series of interventions considered by the WHO as ineffective, or used in an inappropriate manner.

To evaluate the variability of three-dimensional automatic counts of ovarian follicles measuring 2-6 to 2-10 mm during the menstrual cycle and to determine if this test can be applied outside the early follicular phase of the menstrual cycle.
in a prospective observational study, serial transvaginal ultrasound scans were performed from April 20, 2013, to October 30, 2014, on infertile patients. Inclusion criteria: age between 18 and 35 years, BMI 18-25 kg/m2, regular menstrual cycles, no history of ovarian surgery and no hormonal changes in TSH, prolactin, fasting insulin or glucose. We excluded patients with ovarian cysts or who did not complete one or more days of the serial transvaginal ultrasound scans. The follicle count was performed in 3D mode ultrasound with a Sono AVC system. Visits were scheduled for the early follicular, mid-follicular, periovulatory and luteal phases of the menstrual cycle.
Forty-five women were included. The Friedman test showed that the total number of follicles measuring 2-6 mmvaried significantly (p = 0.001) across the four periods of the menstrual cycle. The Paired Student t-test showed a significant increase in 2-6 mm follicle count from the mid-follicular and periovulatory phase to the luteal phase. We found no significant intra-cycle variation between the small follicles (2-6 mm) in the early follicular, mid-follicular and periovulatory phases. The Friedman test showed that the total number of follicles measuring 2-10 mm varied significantly (p = 0.003) across the menstrual cycle.
The variation of three-dimensional automatic counts of 2-6 mm follicles in the early follicular, mid-follicular and periovulatory phases was not statistically significant. The significant variability in the counts of follicles measuring 2-10 mm across the menstrual cycle does not permit this examination to be performed side the early follicular phase.

To evaluate sexual function in women undergoing assisted reproductive techniques.
This is a case-control study including 278 women assisted in Human Reproduction services and at the Gynecology Clinic of the University Hospital, Federal University of Goiás, Brazil. The women were divided into a study group (168 infertile women) and a control group (110 fertile women), and they answered the Female Sexual Function Index (FSFI) questionnaire used the assess the sexual function. We calculated the odds ratio (OR) for the chance of sexual dysfunction in infertile women (p<0.05).
Out of the analyzed women, 33.09% reported sexual dysfunction, with no difference in the FSFI score between groups (p=0.29). The prevalence of sexual dysfunction was of 36.30% among infertile women and 28.18% among fertile women; however, there was no difference between FSFI scores (p=0.36). The desire and arousal domains were significantly different among infertile women (p=0.01). Infertile women had the same chances of having sexual dysfunction as fertile women (OR=1.4, 95%CI 0.8–2.4; p=0.2).
There were no differences between infertile and fertile women. Infertile women undergoing assisted reproduction techniques require professional approach to sexual health regarding desire and arousal.

To analyze the serological, anatomopathological and parasitological results obtained from abortive material in order to detect infections with the risk of vertical transmission, with emphasis on toxoplasmosis.
A cross-sectional cohort study was conducted in order to determine the prevalence of infectoparasitic diseases. A total of 105 women who suffered spontaneous complete or incomplete abortion participated in the study. The women were interviewed, answered a questionnaire and had their blood and abortive material collected. Immunological tests were carried out in order to detect toxoplasmosis, Chagas disease, rubeola, cytomegalovirus and syphilis, and anatomopathological analysis of the ovular remains was performed.
55% of the women studied were 20 to 30 years old. Most of them (68%) presented a gestational age between the 7th and 14th week. 54.3% of the women had complete or incomplete high school education. Serological analysis showed cytomegalovirus (CMV) as the most common vertically transmitted infection with 97.1% positivity, followed by rubeola with 95.2%. Toxoplasmosis showed 54.3% positivity, Chagas disease 1.9% and syphilis 0.95%. Anatomopathological analysis showed inflammation in 63.1% of the cases and absence of inflammation in 34%. The results of the serological, anatomopathological and parasitological analysis of the 105 participants showed that 57 women were T. gondii positive. However, none showed positivity in the polymerase chain reaction (PCR) or in mouse inoculation.
The prevalence of diseases with the risk of vertical transmission is important in women with spontaneous abortion, indicating the need for more research in order to investigate the etiology of abortion.

PURPOSES: To investigate the effect of an individualized and supervised exercise program for the pelvic floor muscles (PFM) in the postpartum period of multiparous women, and to verify the correlation between two methods used to assess PFM strength. METHODS: An open clinical trial was performed with puerperal, multiparous women aged 18 to 35 years. The sample consisted of 23 puerperal women divided into two groups: Intervention Group (IG, n=11) and Control Group (CG, n=12). The puerperal women in IG participated in an eight-week PFM exercise program, twice a week. The puerperal women in CG did not receive any recommendations regarding exercise. PFM strength was assessed using digital vaginal palpation and a perineometer. The statistical analysis was performed using the following tests: Fisher's exact, c², Student's t, Kolmogorov-Smirnov for two samples, and Pearson's correlation coefficient. Significance was defined as p<0.05. RESULTS: The participants' mean age was 24±4.5 years in IG and 25.3±4 years in CG (p=0.4). After the exercise program, a significant difference was found between the groups in both modalities of muscle strength assessment (p<0.001). The two muscle strength assessment methods showed a significant correlation in both assessments (1st assessment: r=0.889, p<0.001; 2nd assessment: r=0.925, p<0.001). CONCLUSIONS: The exercise program promoted a significant improvement in PFM strength. Good correlation was observed between digital vaginal palpation and a perineometer, which indicates that vaginal palpation can be used in clinical practice, since it is an inexpensive method that demonstrated significant correlation with an objective method, i.e. the use of a perioneometer.
