Abstract
INTRODUCTION Suicide is a worldwide health concern and up to date there is no good predictor of it except a previous suicide attempt. Therefore, there are increasing efforts in the understanding of which factors, genetic or environmental, are associated with suicide behaviour. OBJECTIVE To review evidence of the effect of childhood trauma and impulsivity on suicidal behavior through a systematic review and meta-analysis. METHODS Searches were conducted on the 12th of June 2021 in the PubMed, Scopus, and Web of Science databases. Two reviewers evaluated each record for eligibility and discussed upon disagreement, when no consensus was reached, a third reviewer was involved to make a decision. RESULTS A total of 11,530 records were identified through the searches. After duplicates were removed, 6,595 records remained to be screened. The full text was sought for 1,561 records. Our qualitative synthesis included 22 studies, from which 9 were included in the meta-analyses. We found a significant effect of sexual abuse, physical abuse, emotional abuse and physical neglect on suicide attempts in the prisoners, and Substance Use Diorder (SUD) subgroups. Moreover, there was a significant effect of Childhood Trauma Questionnaire (CTQ) total score and emotional neglect dimension for all the subgroups. CONCLUSION The present study has provided an overview of the state-of-the-art research on childhood trauma and impulsivity and their association with suicidal behavior and quantified their effects on suicide attempts. Hopefully this evidence will be considered in future research and harnessed for clinical gain in detection and treatment of suicide behaviour.

Abstract
OBJECTIVE The Mini International Neuropsychiatric Interview (MINI) is one of the most used instruments for the assessment of Mental Disorders, playing an essential role in psychiatric research and in clinical and hospital practice. Despite this, the accuracy of the MINI, when used by a psychiatrist, is poorly studied, particularly in relation to Bipolar Disorder (BD). The early diagnosis of BD and Major Depressive Disorder (MDD) is extremely important, as it provides an opportunity for intervention that can reduce the impact on the patient's daily life and functionality. As such, this study assesses the suitability of MINI for diagnosing BD or MDD in a sample of patients with mood disorders. METHOD Agreement between the MINI and the clinical interview was assessed in a sample of 347 outpatients by calculating Cohen's kappa, sensitivity, specificity, positive predictive value, negative predictive value, and the area under the curve (AUC). RESULTS The sample consisted of 347 patients with mood disorders. 279 were women (80.40%), 105 (30.3%) were diagnosed with MDD and 242 (69.7%) with BD from the assessment performed in the clinical interview. In the MINI assessment, 97 individuals (28%) were classified with a diagnosis of MDD and 250 (72%) with BD. We found a sensitivity of 87.2% and specificity of 62.8% for the MINI in the diagnosis of BD and a Cohen's kappa between the MINI and the clinical interview of 0.51. The AUC was 0.75. CONCLUSIONS MINI has greater sensitivity (87.2%) for the diagnosis of BD and greater specificity (87.2%) for the diagnosis of MDD. In addition, the moderate Cohen kappa (0.51) and AUC (0.75) values between the MINI and the clinical interview are acceptable when considering most available psychiatric diagnostic tools.

Abstract
INTRODUCTION The handling of antineoplastic drugs should follow strict supervision and safety rules to minimize the occupational exposure risks to professionals involved. The external surface contamination of drug vials is recognized as a health risk. So, our goal was to determine if there is residual contamination on the vials and containers surface of the antineoplastic drugs doxorubicin (DOX) and cyclophosphamide (CP). METHODS A cross-sectional study was conducted. Samples were collected using a uniform sampling procedure on the inner surfaces of the packages/boxes and the outer surfaces of the vials. The analyzes were executed by high-performance liquid chromatography/mass spectrometry (UHPLC-MS/MS). RESULTS A total of 209 samples were analyzed, 66 of CP and 143 of DOX. CP levels were detected in nine samples (13.63%), three were below the lower limit of quantification (LLQ) and the other six had contamination levels ranging from 1.24 to 28.04 ng/filter. DOX levels were detected in 36 samples (25.17%), two were below the LLQ and the others had levels between 1.32 and 664.84 ng/filter. The majority of samples with residual contamination were in vials (80.0%), however, boxes also showed contamination. CONCLUSIONS The results revealed the presence of residual contamination in the vials and packages of CP and DOX drugs. Although the residues found in each sample are small, special care should be taken in the handling and disposal of the antineoplastic drugs. The use of personal protective equipment is fundamental while handling the vials and packaging of cytotoxic drugs.

Abstract
Abstract
Study question
Do androgen levels impact oocyte yield during ovarian stimulation and how predictive are they for distinct ovarian response?
Summary answer
Testosterone positively correlates with the number of oocytes retrieved in all patients. DHEA-S appears more specific by only correlating significantly in poor responding women.
What is known already
Androgens are involved in the initiation of primordial follicle recruitment and early development. Testosterone and DHEA-S increase the number of growing follicles by reducing follicular atresia. A reduction in androgen levels can be observed with diminished ovarian reserve and advanced age. To standardize the definition of POR Bologna criteria have been elaborated including age, laboratory or sonographic ovarian reserve and low ovarian response in previous stimulations. The mentioned markers have been reviewed concerning its predictive power for POR by the POSEIDON analysis and divided into four subgroups. To date androgen levels are not raised to stratify POR in these classifications.
Study design, size, duration
All women were recruited in the division for reproductive medicine at the University Hospital Heidelberg. The patients’ files were retrospectively analyzed for androgen levels before ovarian stimulation and outcome. A classification between poor and normal response was performed according to Bologna criteria.
Participants/materials, setting, methods
All patients provided written informed consent. Blood samples were analyzed from serum drawn on day 2 to 5 of the menstrual cycle before ovarian stimulation. Statistical analysis was performed with SPSS; statistical significance was set to p < = 0.05.
Main results and the role of chance
Valid data for analysis was available in 335 cycles, 238 were scaled in normal (NOR), 97 in poor ovarian response (POR). Statistics in both subgroups were performed concerning age, AMH, count of retrieved oocytes, DHEA-S and testosterone with significant lower AMH as well as androgen levels, oocyte yields and a higher median age in the POR group. An expected significant positive correlation between AMH and retrieved oocytes was confirmed in both subgroups (p=.000 and .004). Increasing age negatively correlates with the number of retrieved oocytes after ovarian stimulation in NOR (p=.003), but not in POR (p=.441) patients suggesting age as less powerful predictive marker for oocyte yield in those patients.
In addition, a positive correlation for testosterone and retrieved oocytes merely reached significance in all analyzed cycles independently of different ovarian responses. On the contrary DHEA-S levels and oocyte counts cohered with a marginal significance (p=.05) only in POR patient cycles. Serum levels for DHEA-S positively correlated with the variable “oocyte count ≥ 3” in the POR group (OR 1.006, 95% CI, 0.999- 1.014
Limitations, reasons for caution
The results are based on a limited sample size. Therefore, results need to be proven in further studies including further aspects affecting ovarian response.
Wider implications of the findings
The significant correlation between pre-stimulatory DHEA-S levels in POR for oocyte yield on the contrary to NOR, supports the experimental supplementation with DHEA in this subgroup, aiming to improve outcomes during ovarian stimulation. Testosterone is less specific for estimating ovarian response in both subgroups.

Abstract
Residency is still considered the gold standard for quality medical training, and acquiring a professional identity as a specialist is one of its central elements. Residents obtain this identity through both the educational environment and direct interaction with peers and supervisors. However, modifications in health care and educational routines during the recent coronavirus disease 2019 (COVID-19) pandemic have significantly impaired these channels. This study is part of a qualitative research project to analyze professional identity formation in a medical residency program in obstetrics and gynecology at a public hospital in southern Brazil. The authors conducted 28 semi-structured interviews with medical residents and preceptors, as well as a focus group with the residents, which was recorded, transcribed, and analyzed in an effort to construct major analytical categories. Restricted movement and physical contact have forced the use of alternative means of interpersonal interaction, such as communication through social media or instant messaging applications. This has also affected educational activities, such as morning rounds, lectures, and seminars. These changes represent a significant impact, especially in Brazil, where physical proximity is an important cultural feature, even in the work and school environments. We speculate that this new type of virtual interaction will also affect the formation of professional identity among obstetrician-gynecologists. These findings suggest that medical residency programs should be attentive to changes in resident training to ensure that the specialist profile and the expected skills, which are consolidated over many years, are not lost.

Abstract
BACKGROUND Pregnancy involves anatomical, physiological, and metabolic changes in a woman's body. However, the effects of these changes on the voice remains unclear, particularly regarding the clinical characteristics. OBJECTIVES We aimed to evaluate changes in vocal and speech acoustic measures and the relationship between them and clinical aspects in women during pregnancy. METHOD A prospective, longitudinal study was carried out with 41 low risk, adult, pregnant women, followed for prenatal care. Demographic and anthropometric data as well as lifestyle habits and health conditions were collected. Voice recordings of sustained vowels, and automatic and spontaneous speech were held over each trimester and analyzed by PRAAT®to evaluate acoustic, aerodynamic, and articulatory measures. RESULTS There were no changes in fundamental frequency, jitter, shimmer, and harmony to noise ratio during pregnancy. Maximum phonation time (MPT), pause rate, and pause duration reduced at the end of pregnancy. MPT was lower in sedentary pregnant women. The fundamental frequency peak rate was higher in eutrophic participants and lower in the third trimester in women with BMI ≥25 kg/m2. Pause rate was higher in pregnant women with BMI ≥25 kg/m2. There was no relationship between sleep quality, reflux, and vocal symptoms and acoustic and aerodynamic measures. CONCLUSIONS Differences were shown in MPT and temporal pause measurements during pregnancy. Acoustic measurements did not change. There was a relationship between acoustic and aerodynamic measures and clinical variables (BMI, physical activity, and body mass gain).

Abstract
BACKGROUND The protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway regulates early follicular activation and follicular pool maintenance in female germline cells. Fragile X mental retardation 1 (FMR1) regulates folliculogenesis and it is variably expressed in patients with Premature Ovary Insufficiency. FMR1 expression is supposed to be linked to AKT/mTOR signaling in an ovarian response dependent manner as demonstrated in recent in vitro and in vivo studies in the female germline in vitro and in vivo. METHODS We evaluated changes in the expression of AKT/mTOR signaling pathway genes by real time PCR in the peripheral blood of 74 patients with Premature Ovarian Insufficiency and 56 fertile controls and correlated their expression with FMR1 expression. RESULTS Expression of the genes AKT1, TSC2, mTOR, and S6K was significantly more abundant in patients with POI than in the controls. For AKT1, TSC2 and mTOR, gene expression was not affected by FMR1-CGG repeat number in the 5´-untranslated region. FMR1 and S6K expression levels, however, were significantly upregulated in patients with POI and an FMR1 premutation. Independent of a premutation, expression of mTOR, S6K, and TSC2 was significantly correlated with that of FMR1 in all patients. Furthermore, when grouped according to ovarian reserve, this effect remained significant only for mTOR and S6K, with higher significance note in patients with Premature Ovarian Insufficiency than in the controls. CONCLUSIONS In Premature ovarian insufficiency patients, activation of AKT/mTOR signaling pathway is remarkable and putatively pathognomonic. Additionally, it seems to be triggered by an FMR1/mTOR/S6K linkage mechanism, most relevant in premutation carriers.

Abstract
OBJECTIVE To evaluate the reproductive and histological characteristics of fresh cultured ovarian tissue from transgender male patients. METHODS An in vitro pilot study in which samples were collected during sex reassignment surgery for transgender male patients. The ovarian cortex was cut into fragments of 2 mm, 3 mm, and 4 mm, and placed in a 96-well plate suitable for cultivation at days 0, 2, 4, 6, and 8, when the histology was analyzed. RESULTS Stromal hyperplasia was observed in all samples, and it was not associated with the obtainment of primordial or primary follicles. Peripheral reduction in cell count was also a recurrent finding. Primordial and primary follicles were identified with a heterogeneous pattern in fragments from the same patient and from different patients, and follicles in more advanced stages of development (secondary and antral) were not found. There was an association between the diameter of the ovarian fragments and the identification of primary follicles (p = 0.036). The number of days in culture was associated with histological signs of tissue damaging in the fragments (p = 0.002). The total number of follicles identified in the samples with 2 mm in diameter was significantly lower than in those that measured 4 mm in diameter (p = 0.031). CONCLUSION A diameter of 4 mm is suitable for ovarian tissue culture with the benefit of ease of handling. Even after prolonged exposure to testosterone, the ovarian fragments presented primordial and primary follicles, maintaining viability throughout the days they were exposed to the culture. Freezing the ovarian cortex of transgender patients who will undergo surgery for gender reassignment would be an interesting option, in the future, for the preservation of fertility.

Abstract
Objective Approximately 15% of the couples suffer from infertility. Half of the cases of infertility are due to male factors. Several sperm function tests have been proposed to evaluate male fertility, but sperm analysis is still the first and most important diagnostic test for male infertility. The prognostic value of semen characteristics such as concentration, morphology and motility markers are often confused with male infertility. Evaluation of seminal parameters and classification for normality remains a frequent topic of discussion. Methods This study evaluated 477 semen samples from men undergoing investigation or infertility treatment between 2011 and 2015. Results The spermograms of 401 patients were deemed abnormal based on the 1999 World Health Organization (WHO) criteria; the number changed to 223 when the spermograms were assessed based on the 2010 WHO criteria and to 200 when Total Motile Sperm Count (TMSC) was used as the criterion. Sperm morphology was the item in the criteria that most significantly changed spermogram classification. Normality parameters became less rigid from 1999 to 2010, thereby significantly changing the proportion of individuals no longer described as infertile/subfertile. Conclusions The classification based on TMSC could not differentiate between fertile and infertile subjects for not taking sperm morphology into account. Nevertheless, it may be helpful in cases where intrauterine insemination is indicated.

Abstract
We aimed to determine whether a functional link with impact on female ovarian reserve exists between FMR1 expression and expression ratios of AKT/mTOR signaling genes in human granulosa cells in vivo, as suggested from prior in vitro data. Three hundred and nine women, who were classified as normal (NOR; n = 225) and poor (POR; n = 84) responders based on their ovarian reserve, were recruited during stimulation for assisted reproductive techniques. Expressions of FMR1 and of key genes of the AKT/mTOR and AKT/FOXO1/3 signaling pathways were comparatively analyzed in their granulosa cells. FMR1 expression in granulosa cells of NOR and POR correlated significantly with AKT1, TSC2, mTOR, and S6K expression. No correlation was found between FMR1 and FOXO1 in all, and FOXO3 expression in POR, patients. AKT1 expression was significantly higher and FOXO1 expression lower in POR samples, whereas AKT1 expression was lower and FOXO1 expression was higher in NOR samples. In human native granulosa cells, FMR1 expression significantly correlated with the expression of key genes of the AKT/mTOR signaling pathway, but not with the FOXO1/3 signaling pathway. Our data point to a functional link between FMR1 expression and expression of the AKT/mTOR signaling pathway genes controlling human follicular maturation.

Abstract
Abstract
Study question
How predictive are gene expression levels of AKT/mTOR-signalling-pathway genes in peripheral blood of patients with premature ovary insufficiency (POI) and is there a link to FMR1-expression?
Summary answer
AKT1, TSC2, mTOR, S6K and FOXO3-expression-levels are significantly upregulated in POI-patients and demonstrate a positive correlation with FMR1-expression-level in case of mTOR-, S6K and FOXO3.
What is known already
The AKT/mTOR-signalling-pathway is involved in a range of cellular functions. In female germline it regulates early follicular-activation and follicular-pool-maintenance. Over the past few years AKT-activation has been experimentally applied to induce follicular maturation in POI-patients. Additionally, first evidence of a linked FMR1 – AKT/mTOR signaling in female germline have been reported.
FMR1 is a major control gene in folliculogenesis. Due to increased (CGG)-triplet-numbers (54 < n < 200) in its 5′-untranslated-region, named premutation, increased FMR1-expression-levels and reduced FMRP-production have been described, associated with POI in 20% of cases. A former study found premutation independent, large transcript-level-variances of FMR1 in leukocyte RNA-samples of POI-patients.
Study design, size, duration
74 POI patients and 56 fertile controls were prospectively enrolled in this study. Accordingly, expression levels of genes associated with the AKT/mTOR-signaling pathway and FMR1 were analyzed and correlated on the mRNA level of their leukocytes.
Participants/materials, setting, methods
All patients provided written informed consent. mRNA was extracted from EDTA blood after lysis; quantitative expression analyses of FMR1, AKT, mTOR, S6K, FOXO3, FOXO1 genes were performed with specific TaqMan-Assays. Statistical analyses was performed with SPSS; statistical significance was set to P < 0.05.
Main results and the role of chance
Gene expression levels of AKT1, TSC2, mTOR, S6K, FOXO3 are significant higher in POI patients compared to controls (P < 0.009 or less).
The rate of FMR1-expression is highly correlated with mTOR-, S6K and FOXO3-expression levels (P < 0.001) in all patients, in addition. When grouped according to ovarian reserve this effect is more pronounced in POI than in control patients. Additionally, the correlation of FMR1 with FOXO3 remained significant only in the POI subgroup.
The upregulation of AKT/mTOR-signaling in POI may reflect a compensative mechanism in POI aiming the activation of the last remaining follicles.
The linkage of FMR1 with AKT/mTOR-signalling in peripheral blood comparable to prior results from germline, support its putative impact on the pathogenesis of POI and other folliculogenesis related disorders, such as poor ovarian response.
Limitations, reasons for caution
Results are based on limited patient numbers. More patients, stratified for age and other risks factors, are needed to further elucidate this mechanism.
Wider implications of the findings
This is the first evidence that FMR1 is linked to an AKT/mTOR activation in POI potentially involved in its pathogenesis. Such a marker in peripheral blood offers a perspective towards its usability as a predictive tool in the diagnostics and prognosis of POI, if results are consistent in further studies.

Abstract
INTRODUCTION Our goal was to demonstrate the effects of occupational exposure to antineoplastic drugs on oxidative stress parameters and DNA damage in health professionals who manipulate and administer antineoplastic drugs in a University Hospital in Southern Brazil. METHODS The case-control study with a longitudinal design, involved 64 individuals, 29 of them pharmacists, pharmacy technicians and nurses who were occupationally exposed to antineoplastic drugs and 35 professionals who were not exposed. Gene mutations were determined by micronucleus from salivary fluid; DNA damage by comet assay and oxidative stress parameters in whole blood were also evaluated. RESULTS All workers exposed to antineoplastic drugs used personal protective equipment (PPE). It was demonstrated that the total nonprotein thiol and thiobarbituric acid reactive substances levels showed interaction between group and time, with higher levels one week after handling/administration of antineoplastic drugs in the exposed group (GEE, p ≤ 0.0001 and p = 0,013, respectively). Additionally, there was a group effect on the activities of the catalase and glutathione peroxidase antioxidant enzymes (GEE, p = 0.027 and p ≤ 0.0001, respectively), and workers occupationally exposed to antineoplastic drugs had higher enzyme activities compared to those not exposed. No genotoxic damage was demonstrated through the evaluated parameters. CONCLUSIONS Despite the correct use of PPE, professionals occupationally exposed to antineoplastic drugs were more susceptible to oxidative stress than those not exposed. The evaluation of the studied parameters is especially important for the definition of conducts and practices in the area, always in search of guaranteeing the establishment of a rational policy to protect workers' health.

Abstract
Introduction
Azoospermia affects about 1% of men, of whom up to 15% inquire about infertility treatment. Information about predictive factors for these couples is very limited.
Patients, Materials and Methods
We performed a retrospective analysis of the clinical records of 118 cycles of intracytoplasmic sperm injection treatment after testicular sperm extraction for male azoospermia carried out between January 2008 and October 2015. Of those, 66 were first, 35 second, and 17 third cycles. Statistical significance was set at p < 0.05. Predictive factors for successful pregnancy were evaluated and included male/female age, male/female body mass index, male/female nicotine use, and histological results of testes biopsies.
Results
Embryo quality and the number of embryos transferred were positively associated with pregnancy success (p = 0.003). Males whose partners conceived had a significantly lower body mass index than those whose partners did not conceive (p = 0.023). Neither female weight nor age nor smoking status of the male or female were significant factors. In cases with tubular atrophy ≥ SIGG grade 4 the chance of pregnancy was poor, irrespective of the existence of mature sperm and the number of cycles performed.
Conclusion
Overweight male patients should be advised about weight reduction prior to treatment, and counseling about success rates should include histological and sperm-positive biopsy results.

Abstract
PURPOSE Female fertility preservation prior to gonadotoxic therapies can be achieved by the cryopreservation of ovarian cortical tissue. Immature oocytes may be recovered during the preparation, matured in vitro and lead to live births, thereby providing an additional option for fertility preservation. The purpose of this study was to test the feasibility of this approach in a setting with unilateral biopsy of a small piece of ovarian tissue and minimal tissue preparation prior to shipment to an external cryobank. METHODS A prospective observational clinical study in an academic center was performed from January 2018 through December 2019. Ovarian tissue was obtained laparoscopically. Immature oocytes were recovered by minimal preparation of the tissue before shipment to an external cryobank for cryopreservation. In vitro maturation was performed on recovered immature oocytes. RESULTS Twelve patients were enrolled. Immature oocytes could be recovered for all. The maturation rate was 38.9% (n = 14/36). Metaphase II (MII) were either directly used for intracytoplasmic sperm injection (ICSI) with a fertilization rate of 66.6% (n = 4/6) or vitrified (n = 8). PNs were cryopreserved (n = 4). Vitrified MII were warmed with a post-warming vitality rate of 75.0% (n = 3/4) and used for ICSI with a fertilization rate of 33.3% (n = 1/3). CONCLUSIONS Immature oocytes can be successfully retrieved from ovarian tissue through minimal tissue preparation prior to shipment to a cryobank, matured in vitro, fertilized and cryopreserved for potential future fertility treatments. The total number of oocytes available for fertility preservation can be increased even without controlled ovarian stimulation in a situation where only ovarian biopsy for cryopreservation is performed.

Abstract
PURPOSE Implantation rates differ according to ovulation induction agents in ART. This study investigates the different local endometrial effects of LH- versus hCG-induced ovulation. METHODS Endometrial stromal cells from healthy patients were cultured with hCG or LH in different concentrations, supplemented with 250 ng/mL hCG and progesterone after 2 and 5 days. In addition after decidualization induction, cells were treated with hCG (50 or 250 ng/mL) or LH (10 or 50 ng/mL) for 3 days. Receptivity markers expression was evaluated by real-time quantitative PCR on day 3 and 6. RESULTS On day 3, non-decidualized cells treated with LH showed an increased expression of IGFBP1, IL-8 and CXCL12 compared to hCG. The expression pattern changed on day 6, where cells treated with hCG showed higher expression of implantation markers compared to LH-treated cells. Furthermore, on day 3, decidualized cells treated with hCG250 showed an increased IL8 and CXCL12 expression compared to LH10. CONCLUSIONS LH seems to modulate the local endometrial expression of receptivity markers earlier compared to hCG; however, the effect is not sustained over time in cells without prior decidualization. Though, in decidualized cells, pattern changed and an earlier positive effect of hCG was shown on IL-8 and CXCL12.

Abstract
Assessing therapeutic response in depression requires scales that adequately measure the core symptoms of depressive symptomatology. The main goal of this study was to assess the psychometric properties of the 17-item Hamilton Depression Rating Scale (HAM-D17) and the 6-item Hamilton Depression Rating Scale (HAM-D6) in patients with Major Depressive Disorder (MDD), bipolar depression and bipolar depression with mixed features. We conducted a reanalysis of a pragmatic clinical trial in an outpatient clinic for mood disorders that included eight weeks of follow-up. A Mokken analysis was performed to evaluate the unidimensionality of the HAM-D17 and HAM-D6, and the Spearman correlation was used to assess concurrent validity between the HAM-D17, the HAM-D6 and quality of life scale (SF-36 and WHOQOL-BREF) scores. A total of 237 patients with a mean age of 40.2 years (±11.7) were included. According to the DSM-IV criteria, 58 (24.5%) were diagnosed with MDD and 73 (30.8%) were diagnosed with bipolar depression. Bipolar depression with mixed features was diagnosed in 106 (44.7%) patients according to the DSM-IV and supplemented by the Cincinnati criteria. Only the HAM-D6 scale proved to be unidimensional, showing strong homogeneity for evaluating MDD, moderate homogeneity for bipolar depression and weak homogeneity for bipolar depression with mixed features. Both the HAM-D17 and the HAM-D6 had inverse, significant correlations at baseline with SF-36 and WHOQOL-BREF scores. This is the first study to include bipolar depression patients with mixed features in an assessment of HAM-D6 unidimensionality.

Abstract
Main goal of this study is to detect the possible alterations in microRNA (miRNA) expression and the pathway targeted in plasma at the time of embryo transfer and pregnancy testing dependent on the assisted reproductive treatment (ART) outcome after ovarian hyperstimulation for in vitro fertilization. Changes in miRNA expression in plasma of women, who became pregnant (n = 6) vs women who failed implantation (n = 6) following day 5 embryo transfer (ET), were investigated at the day of ET and pregnancy testing (PT). Protein expression to validate the finding was performed with a sample size of n = 20 (10 per group) using enzyme-linked immunosorbent assay. Enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed using DIANA-miRPath, v3.0 software based on predicted targets by DIANA-microT-CDS. 4 miRNAs could be identified as possible biomarkers for implantation success. The 11 miRNAs showing the highest significant alterations were all associated with the regulation of WNT3 and WNT7a. While WNT7a presented with a significant decrease between ET and PT in case of ongoing pregnancy, women with implantation failure showed unaltered concentrations. WNT3 presented with a significant decrease in both groups. However, the loss of WNT3 between ET and PT was significantly higher in patients who became pregnant. Main limitation of this prospective study is its small sample size, defining it as a pilot analysis. To conclude, we could demonstrate a significant change in miRNA profile dependent on the ART outcome affecting Wnt pathway. Our findings indicate a possible prospective use of miRNA as biomarkers for implantation success.

Abstract
Uterine leiomyomas are the most common benign smooth muscle cell tumors in women. Estrogen (E2), progesterone (P4) and environmental factors play important roles in the development of these tumors. New treatments, such as mifepristone, have been proposed. We evaluated the gene expression of total (PRT) and B (PRB) progesterone receptors, and the histone acetyltransferase (HAT) and deacetylase (HDAC) activity after treatment with E2, P4 and mifepristone (RU486) in primary cell cultures from uterine leiomyoma and normal myometrium. Compared to myometrium, uterine leiomyoma cells showed an increase in PRT mRNA expression when treated with E2, and increase in PRB mRNA expression when treated with E2 and P4. Treatment with mifepristone had no significant impact on mRNA expression in these cells. The HDAC activity was higher in uterine leiomyoma compared to myometrial cells after treatment with E2 and E2 + P4 + mifepristone. HAT activity was barely detectable. Our results suggest that ovarian steroid hormones modulate PR, and mifepristone was unable to decrease PRT and PRB mRNA. The higher activity of HDAC leiomyoma cells could be involved in transcriptional repression of genes implicated in normal myometrium cell function, contributing to the maintenance and growth of uterine leiomyoma.

Abstract
PURPOSE To identify the factors associated with weight retention after pregnancy. METHODS A cohort study was performed with 145 women receiving maternity care at a hospital in Caxias do Sul, Rio Grande do Sul, Brazil, aged 19 to 45 years, between weeks 38 and 42 of pregnancy. The patients were evaluated at one month, three months, and six months after delivery. Student's t-test or one-way analysis of variance (ANOVA) was used to compare groups, as indicated; correlations were assessed with Pearson's and Spearman's tests, as indicated; to identify and evaluate confounders independently associated with total weight loss, a multivariate linear regression analysis was performed and statistical significance was set at p ≤ 0.05. RESULTS There was a significant positive association between total weight gain - and a negative association with physical exercise during pregnancy - with total weight loss. Higher parity, inter-pregnancy interval, calorie intake, pre-pregnancy body mass index (BMI), weight gain related to pre-pregnancy BMI, presence and severity of depression, and lack of exclusive breastfeeding were directly associated with lower weight loss. Among nominal variables, level of education and marital status were significantly associated with total weight loss. CONCLUSION In the present study, lower weight retention in the postpartum period was associated with higher educational attainment and with being married. Normal or below-normal pre-pregnancy BMI, physical activity and adequate weight gain during pregnancy, lower parity, exclusive breastfeeding for a longer period, appropriate or low calorie intake, and absence of depression were also determinants of reduced weight retention.

Abstract
Aim To assess ovarian reserve (OVR) by means of follicle-stimulating hormone (FSH), anti-Müllerian hormone (AMH), and antral follicle count (AFC) measurement in eumenorrheic women with breast cancer, exposed to gonadotoxic chemotherapy. Method Fifty-two women (35.3 ± 3.8 years old) with breast cancer and undergoing cyclophosphamide-containing chemotherapy were enrolled. The assessment was performed before chemotherapy (T1) and after 2 (T2) and 6 months (T3). Results Six months after chemotherapy, the prevalence of regular cycles was 60%. Anti-Müllerian hormone decreased down to undetectable levels at T2 and T3 (T1: 2.53 [1.00-5.31]; T2 < 0.08; T3: < 0.08 [< 0.08-1.07] ng/mL), (p < 0.0001). Antral follicle count was 11 [8.0-13.5] follicles at T1 and lower at T2 (5.50 [3.75-8.0] and T3 (5.0 [2.5-7.0]) (p < 0.0001). In patients who remained with regular cycles during chemotherapy or resumed normal menses, FSH and estradiol levels remained unchanged. Conclusion Anti-Müllerian hormone and AFC are useful as markers of OVR decline in women exposed to chemotherapy. Follicle-stimulating hormone is only adequate in women who become amenorrheic.

Abstract
In vitro oocyte maturation presents many advantages and its success is related to the selection of fully grown oocytes. In animal models, staining of cumulus-oocyte complexes (COCs) with Brilliant Cresyl Blue (BCB) is widely used for this selection. However, a lack of information about the safety of BCB makes its applicability in humans questionable. Because granulosa and cumulus cells have a close relationship with the oocyte and taking into account that follicular cells are also exposed to BCB when this pre-selection method is applied, we aimed to evaluate the effects of BCB on human follicular cells exposed to BCB. Cytotoxicity tests (Sulforhodamine B and Neutral Red Uptake) and gene and protein expression of elements related to the cell cycle (BAX, BCL2, TP53 and CDKN1A), as well as to cell death and metabolism (GAPDH), glucose consumption, and estradiol and progesterone secretion, were examined in granulosa and cumulus cells with and without exposure to BCB. Regardless estradiol secretion and glucose consumption, all other evaluations presented similar results between control and treated (BCB) groups, independently of cell type. Therefore, our results demonstrate convincingly that BCB seems to be safe for use in humans and it should encourage future studies to evaluate the development of embryos derived from human oocytes selected by BCB staining.

Abstract
In order to improve our understanding of the potential preventive and therapeutic role of metformin, the present study aimed to investigate the capability of low-dose metformin in the efficient inhibition of cancer development and the reduction of the metastasis of endometrial adenocarcinoma type I and primary endometrial epithelial cells (eEPs), with the drug acting as a treatment in a hyperinsulinemic environment exposed to high and normal glucose conditions. The Ishikawa endometrial adenocarcinoma cell line and primary eEPs were exposed to an environment with high (17 mM) or normal glucose (5 mM) and treated with insulin, low-dose metformin (0.1 mM) or a combined treatment. Metastatic potential was assessed by migration and invasion assays, and relative cell proliferation was determined. Metformin at a low dose potently inhibited the insulin action, decreasing the ability of the endometrial cancer (EC) cell line to migrate and invade in a high and normal glucose environment, and decreasing the migration ability of the primary eEPs. In the EC cell line, the insulin treatment increased the proliferation, without any subsequent reduction of proliferation by the addition of 0.1 mM metformin; however, relative cell proliferation sensitivity to metformin was observed in the range between 1 and 5 mM regardless of the glucose concentration present. Overall, metformin at 0.1 mM is not efficient enough to decrease the proliferation in an EC cell line. However, at this concentration, metformin can inhibit the insulin action in endometrial epithelial cancer cells, demonstrating an anti-metastatic effect in high and normal glucose environments.

Abstract
BACKGROUND The aim of the present study was to evaluate agreement between three pairs formed by one of three mania scales (Young Mania Rating Scale [YMRS], Bech-Rafaelsen Mania Scale [BRMS], or the Clinician-Administered Rating Scale for Mania [CARS-M]) and a single depression scale (21-item Hamilton Depression Rating Scale [21-HAM-D]) for evaluation of response to mood stabilizers in patients with mixed bipolar disorder. METHODS Between 2010 and 2014, 68 consecutive bipolar type I and II outpatients with mixed depression as per DSM-IV-TR and Cincinnati criteria were included in this 8-week open-label trial to randomly receive carbamazepine, lithium carbonate, or valproic acid as monotherapy. RESULTS Patterns of response (defined as a reduction of at least 50% in one of the mania scales and on the 21-HAM-D) were strikingly similar: 21-HAM-D+YMRS=22.1%, 21-HAM-D+BRMS=20.6%, and 21-HAM-D+CARS-M=23.5% (p<0.368). Assessment of agreement revealed very high kappa coefficients: 21-HAM-D+YMRS vs. 21-HAM-D+CARS-M, kappa=0.87; 21-HAM-D+YMRS vs. 21-HAM-D+BRMS, kappa=0.78; 21-HAM-D+CARS-M vs. 21-HAM-D+BRMS, kappa=0.91 (p<0.001). LIMITATIONS The decision to combine a depression rating scale with any one mania rating scale to assess treatment response in patients with mixed depression is questionable. CONCLUSIONS The present study suggests that any one of the three tested mania rating scales (YMRS, BRMS, and CARS-M) can be combined with the 21-HAM-D to assess treatment response in patients with mixed bipolar disorder. This should give clinicians an added measure of confidence in using this strategy until valid, and specific instruments are developed for assessment of mixed states.

Abstract
Background A cohort study was performed to identify ovarian reserve markers (ORM) that predicts amenorrhea or oligomenorrhea 6 months after cyclophosphamide CTX in women with breast cancer. Methods 52 eumenorrheic patients with breast cancer were enrolled. FSH, anti-Müllerian hormone (AMH), antral follicles count (AFC) were measured before and 6 months after CTX. A logistic regression for independent samples and determination of the ROC curve were performed. Results The age of 32 years presented 96 % of sensitivity and 39 % of specificity to predict amenorrhea or oligomenorrhea with ROC area under the curve (AUC) of 0.77. ovarian reserve marker (ORM) with power to predict amenorrhea or oligomenorrhea in women after CTX were AMH <3.32 ng/mL (sensitivity of 85 %, specificity of 75 % and AUC 0.87), AFC <13 follicles (sensitivity 81 %, specificity 62 %, AUC 0.81). AMH cutoff to predict amenorrhea was 1.87 ng/mL (sensitivity 82 %, specificity 83 %, AUC 0.84) and AFC cutoff was 9 follicles (sensitivity 71 %, specificity 78 %, AUC 0.73). Conclusions ≥32-years-old women, AMH <3.32 ng/mL and AFC <13 follicles determined significantly higher risk of amenorrhea or oligomenorrhea after CTX with cyclophosphamide. The ORM age (≥32 years) analyzed together with AMH or AFC increases sensitivity and specificity in predicting amenorrhea or oligomenorrhea.

Abstract
OBJECTIVES In the female life cycle, hormonal fluctuations may result in impaired verbal efficiency and vocal worsening during the premenstrual phase. Oral contraceptives may interfere with vocal range. Voice, resonance, and articulation variations clarify speech content. To investigate the phonoarticulatory sounds produced by oral contraceptive users aged between 20 and 30 years. STUDY DESIGN This is a cross-sectional study. METHODS Our study included four groups of women (n = 66): two groups used low-dose oral contraceptives and two groups did not use any oral contraceptives. Questionnaires and sound records were used. Acoustic analysis was performed using the Computerized Speech Laboratory program, Model 4341 (Kay Elemetrics Corp, Lincoln Park, New Jersey). The statistical analysis of the SPPS database, version 13.0, was performed by means of generalized estimating equation. RESULTS In the groups that did not use oral contraceptives, sustained vowel tones were more acute in the two phases and cycles of women older than 25 years (w/oOC1, 175 ± 74 to 190 ± 55 Hz; w/oOC2, 194 ± 56 to 210 ± 32 Hz). At the midfollicular phase (Fph) and midluteal phase (Lph) of the two cycles, the speed of the speech was slower in this group (w/oOC1: Fph, 5.3 ± 1.6/s and Lph, 5.4 ± 1.4/s; w/oOC2: Fph, 4.5 ± 1.7/s and Lph, 4.8 ± 1.1/s). In both groups that used oral contraceptives, there was a higher modulation frequency in the sentences when compared with nonusers (OC1, 33 ± 10 Hz; w/oOC1, 28 ± 10 Hz; OC2, 34 ± 10 Hz; w/oOC2, 27 ± 10 Hz). Vocal intensity was closer between the OC1 (62 ± 4 dB), w/oOC1 (61 ± 3 dB), and OC2 (63 ± 4 dB) groups when compared with the w/oOC2 (67 ± 6 dB) group. CONCLUSIONS We demonstrated hormonal influences on speech articulation of contraceptive users and nonusers.

Abstract
OBJECTIVE To assess the effect of metformin on gene and protein expression of insulin receptor (IR) and IGF-1 (IGF-1R) receptor in human endometrial stromal cells after stimulation with androgen and insulin. STUDY DESIGN Primary culture of endometrial stromal cells stimulated with estrogen, progesterone with or without androgen or insulin, and treated with metformin for 24 and 48 h, followed by RNA (qRT-PCR) and protein (Western blot) extraction and analysis. RESULTS IR gene expression was increased after treatment with insulin (2.9-fold change, p = 0.027) and further after metformin treatment (4.7-fold change, p < 0.001), and in IGF-1R, the group treated with insulin (1.83-fold change) and metformin (1.78-fold change) showed more expression, than control group (p < 0.001). Similarly, IR protein expression was increased after addition of metformin and insulin (249,869 ± 15,878) in relation to the other groups (p < 0.001). Furthermore, cells treated with insulin (153,634 ± 29,123) and androgen plus insulin (162,854 ± 86,258) had a higher IR protein expression compared to control (104,654 ± 5,634) and androgen group (71,595 ± 3,439, (p = 0.045 and 0.021). In groups treated with insulin (127,711 ± 4,591) and androgen plus insulin (151,098 ± 5,194) the protein IGF-1R was increased compared to control (79,355 ± 3,470) and the androgen-only group (79,326 ± 3,114) (p < 0.001). CONCLUSION Metformin in combination with insulin increased IR protein and gene expressions, while it had no influence on the protein expression of IGF-1R in endometrial stromal cells.

Abstract
BACKGROUND/AIM Granulosa cells are the source of the most important ovarian steroids. Even in patients without significant improvement in metabolic parameters, metformin has apparently an important effect on the ovary. The aim of this study was to evaluate gene and protein expression of an insulin receptor (IR), insulin-like growth factor-1 (IGF1) receptor (IGF1R) and aromatase in granulosa cells treated with metformin and insulin. METHODS Luteinized granulosa cells were collected from 27 patients during in vitro fertilization procedures. Cells were isolated, stored in culture for 24 h and divided into four groups: control; metformin for 30 min, and metformin for 30 min plus insulin for 30 or 60 min. RESULTS IR and IGF1R mRNA expression was significantly enhanced by metformin but was not affected by insulin. Aromatase mRNA expression was significantly reduced in metformin-incubated cells following stimulation with insulin for 30 min. No statistical differences were found in IGF1R and aromatase protein expression, and IR expression was not detected. CONCLUSION A direct effect of metformin on the gene expression of IGF1R, IR and aromatase was observed. Further studies should investigate the role of IGF1R, IR and aromatase in ovarian physiology for a better understanding of the effect of metformin.

Abstract
INTRODUCTION The present study compared the DNA fragmentation in human sperm samples with reduced, physiological, and increased viscosity in order to evaluate whether the process used to reduce viscosity (expulsion of semen through a needle and syringe) alters significantly sperm DNA fragmentation. METHODS The seminal parameters of semen samples from 123 patients were evaluated and classified according to their viscosity. Samples with increased viscosity were submitted to a process of expulsion of semen through a 10-mL syringe and an 18-gauge (18G) needle to reduce the seminal viscosity. The DNA fragmentation of all samples was analysed using TUNEL assay (Terminal deoxynucleotidyl transferase mediated dUTP Nick-end labelling assay); in samples with increased viscosity, the fragmentation was assessed before and after the process of expulsion with syringe and needle. RESULTS There was no difference in DNA fragmentation between groups with different viscosity (P = 0.857). A significantly increase in sperm DNA fragmentation after expulsion of hyperviscous semen through the syringe was observed (P = 0.035). CONCLUSION There was no difference in DNA fragmentation rate between samples with reduced, increased and physiological viscosities; however, the physical process of expulsion of semen through a syringe and needle increased sperm DNA fragmentation.

Abstract
OBJECTIVES: to compare the endometrial effects and uterine bleeding patterns associated with treatment using (1) levonorgestrel-releasing intrauterine system (LNG-IUS) and estradiol (1 mg/day, p.o.) or (2) orally administered drospirenone (2 mg/day) andestradiol (1 mg/day). METHODS: thirty-four patients (aged 52.53 ± 4.44 in the LNG-IUS group and 53.15 ± 4.018 in the DRSP group) were randomized. The severity of menopausal symptoms was evaluated using the Kupperman index every three months. Transvaginal ultrasound, hysteroscopy and histological evaluation were repeated after 12 months. During this period, patients kept menstrual calendars. All categorical variables were described as percentages. Variables were tested for normal distribution and Student's t test was applied for independent samples and ANOVA forrepeated measures when appropriate. Data were considered to be significant when p<0.05. RESULTS: slight vaginal bleeding was reported in the first month of treatment by 53.3% of patients from the LNG-IUS/estradiol group compared with 7.7% of patients from the drospirenone/estradiol group. There were no differences in endometrial thickness between the two groups throughout the study period. End-of-study histological findings showed atrophic endometrium in 53.3% of patients in the LNG-IUS/estradiol group compared with 76.9% of patients in the drospirenone/estradiol group. CONCLUSIONS: our results suggest good endometrial protection with both HT regimens.

Abstract
Background To develop a minimally invasive ovarian cauterization technique under transvaginal ultrasound control and evaluate the safety and feasability of monopolar cauterization to cause ovarian injury using female cattle of reproductive age as an experimental model. Method Experimental study in a university research center was performed. Eleven female bovines of reproductive age were submitted to monopolar transvaginal ovarian cauterization. The right ovary (RO) was punctured at four sites and 40 W was applied for 5 s at each point, resulting in a total of 800 J (Joules) of thermal energy. In the left ovary (LO), the procedure was similar, with the same time and 80 W, resulting in a thermal energy of 1600 J. Macroscopic and microscopic lesions were assessed. Results Of 22 ovaries punctured, 20 were cauterized and exhibited macroscopic and typical microscopic lesions. No lesions could be found in the needle path. The measures of the areas of microscopic electrocautery lesions calculated estimating a cylindrical volume showed a median of 1.12% in the right ovary and 1.65% in the left ovary. When the estimate was calculated by spherical shape, the medians were 1.77% in the right ovary and 3.06% in the left ovary. There was a statistically significant difference in these two estimates (sphere, p = 0.008; cylinder, p = 0.021). Conclusion The experimental animal model described for transvaginal ultrasound-guided ovarian needle cauterization seems to be feasible. The ovaries were successfully cauterized without injuries in needle path and more energy resulted in significantly more thermal lesion. The safety and effectiveness of this technique, theoretically less invasive than current ovarian drilling methods, could be tested in anovulatory women with PCOS.

Abstract
OBJECTIVE To assess the expression and regulation of antilipoprotein D (ApoD) and antilipoprotein E (ApoE) in human endometrium. STUDY DESIGN Endometrial biopsies from healthy, regularly cycling women were collected during the late proliferative and mid-secretory phase. mRNA gene expression of ApoD and ApoE was determined using real-time PCR in whole tissue, in isolated stromal (ESC), epithelial (EEC) and CD45(+) leukocytes (EIC), as well as after hormonal stimulation of ESC and EEC in vitro. Protein expression was analyzed using immunohistochemistry. RESULTS ApoD and ApoE mRNA was expressed in all cell types examined. A rise in ApoD mRNA expression was seen in whole endometrium, ESC, and EEC in the secretory phase, as well as after hormonal stimulation of ESC and EEC in vitro. ApoE mRNA was significantly upregulated in whole endometrium of secretory phase biopsies, while its expression was not altered by progesterone in vitro. Immunohistochemistry of whole endometrial tissue localized ApoD mainly in ESC and EEC. While ApoE was localized slightly in ESC, it was particularly noted on the surface of secretory phase endothelial cells. CONCLUSION We demonstrate for the first time the cell-type and cycle dependent expression of ApoD and ApoE within human endometrium, suggesting their role in endometrial modulation.

Abstract
Anal cancer is a rare disease. Nevertheless, it may be a reason for concern among groups in which its incidence is increasing: those who engage in anoreceptive intercourse, promiscuous persons, and those with sexually transmitted infections (HPV and HIV). The aim of this study was to evaluate the prevalence of abnormal anal cytology in women infected with HIV seen at Hospital de Clínicas de Porto Alegre, Brazil. A cross-sectional design was used. Anal smear screening was offered to all women infected with HIV seen at the hospital's outpatient sexually transmitted infections clinic from March 2006 to March 2008. A total of 184 patients were thus enrolled. Only patients who gave written consent were included in the study. The prevalence of abnormal anal cytology was 14.1% (26 patients). Twenty-two patients presented atypical squamous cells of undetermined significance, and four exhibited low-grade intraepithelial neoplasia. Initially, abnormal anal cytology was significantly associated with age, number of pregnancies, smoking, abnormal cervical cytology, CD4⁺ < 200 cells/mm³ and hepatitis C co-infection. After adjustment, only CD4⁺ < 200 cells/mm³ and smoking were found to increase the risk of altered anal cytology. The anal Pap method described is simple and can be used for screening in cohorts of HIV-positive women who are at risk of developing anal carcinoma, mainly those with CD4⁺ counts <200 cells/mm³ and smokers.

Abstract
OBJECTIVES To assess the relationship between cold-knife conization specimen height, cervical intraepithelial neoplasia (CIN II/III) size and endocervical margin involvement by CIN II/II. STUDY DESIGN A cross-sectional study was performed. Cold knife cone specimens with a diagnosis of CIN II/III were selected. Epidemiological data and pathology reports were obtained through a chart review. All samples from each cone specimen showing CIN II/III and the squamocolumnar junction were selected. Cone height (mean ± standard deviation), intraepithelial lesion size, and size of endocervical surgical margins were measured. RESULTS Four hundred and forty-seven samples were analyzed from 97 cone specimens. Section size ranged from 3.4 to 29.7 mm, tumor size from 0.3 to 17.5mm, and tumor distance from the endocervical margin, from 0.0 to 22.0mm. Age and parity were similar in the positive vs. negative margin groups (37.6 ± 10.0 years vs. 37.7 ± 11.9 years respectively, p=0.952, and 2.2 ± 1.7 births vs. 2.6 ± 1.9 births respectively, p=0.804), whereas cone height (22.4 ± 6.9 mm vs. 17.1 ± 5.6mm, p=0.013) and tumor size (6.12 ± 3.25 mm vs. 10.6 ± 4.45 mm, p<0.001) were significantly different in negative vs. positive margin groups respectively. CONCLUSIONS Use of cone height to identify the likelihood of negative margins enables better estimation of the risk-benefit ratio of greater risks of bleeding, stenosis, and obstetric complications (cervical incompetence) versus greater risks of residual and recurrent disease.

Abstract
BACKGROUND Leiomyomas are the most common tumors of the female reproductive tract and a major public health problem. The mechanism of tumorigenesis is unknown, but evidence suggests that estrogens regulate cell proliferation and myoma growth. This effect might be due to different amounts of estrogen receptors (ERα and ERβ) in normal and myoma tissues and overexpression of aromatase P450 in myomas. PURPOSE To assess protein expression of ERs and aromatase in leiomyomas and normal adjacent myometrium of premenopausal women. METHODS Samples were collected from 12 premenopausal women admitted for abdominal hysterectomy due to fibroids. RESULTS The protein expression of ERα, ERβ and aromatase was similar in leiomyoma and normal myometrium (p = 0.239, p = 0.695 and p = 0.203, respectively). CONCLUSIONS In this analysis of 12 matched leiomyoma and myometrial samples, the data do not support the theory that overexpression ERα, ERβ and aromatase in uterine leiomyomas compared to adjacent myometrium are the cause of tumor growth. The estrogens may exert their growth-stimulatory effects on leiomyomas intermediated by other elements, such as cytokines and growth or apoptosis factors. The effect of estrogen on the growth and development of fibroids is complex and far from being completely understood.

Abstract
PURPOSE To assess gene and protein expression of progesterone receptor isoforms A and B, cell cycle regulators p53 and p21 in leiomyoma and myometrium. METHODS Samples were collected from 14 patients in reproductive age who underwent abdominal hysterectomy. Gene expression of PRA, PRB, p53 and p21 was analyzed by real-time PCR. Protein expression was assessed by Western blots. RESULTS There was no change in gene and protein expression of PRA and PRB in both tissues. The ratio between isoforms (PRA:PRB) was not different between tissues and showed a strong correlation (r = 0.767, P = 0.004). The analysis of gene expression and protein showed increased levels of mRNA and protein p53 in leiomyoma compared to myometrium (P = 0.030 and P = 0.002, respectively). The same increase was observed in p21 mRNA levels (P = 0.016) and protein p21 levels (P = 0.026) in samples of uterine leiomyoma. CONCLUSIONS PRA:PRB ratio is similar in normal myometrium and leiomyomas. p53 and p21 mRNA and protein levels are increased in leiomyomas.

Abstract
BACKGROUND Some techniques of transvaginal ovarian drilling have been previously described. Nevertheless a monopolar transvaginal ovarian cauterization, that use the expertise and safety of transvaginal puncture for oocyte captation seems to be an easier and feasible approach. The aim of this study was to develop a minimally invasive ovarian cauterization technique under transvaginal ultrasound control, and to evaluate the safety of the transvaginal ovarian monopolar cauterization, female sheep at reproductive age were used as an experimental model. FINDINGS An experimental study was performed in a university research center. Seventeen female sheep (15 Corriedale e 2 Suffolk) in reproductive age were submitted to transvaginal ovarian cauterization with a monopolar Valleylab Force 2 electrocautery. Macroscopic and microscopic lesions were assessed. Ovarian size were 1.31 cm2 ± 0,43 (Corriedale) and 3.41 cm2 ± 0,64 (Suffolk). From 30 ovaries from Corriedale sheep punctured, only 3 were cauterized, presenting macroscopic and typical microscopic lesion. In the Suffolk sheep group, only one ovary was cauterized. No lesion could be found in the needle path. CONCLUSIONS This is the first experimental animal model described for ovarian cauterization needle guided by transvaginal ultrasound. The sheep does not seem to be the ideal animal model to study this technique. Another animal model, whose ovaries are better identified by transvaginal ultrasound should be sought for this technique, theoretically less invasive, before it could be offered safely to women with polycystic ovary syndrome.

Abstract
CONTEXT AND OBJECTIVE Preeclampsia is a multi-systemic disease and one of the most frequent severe health problems during pregnancy. Binding of insulin triggers phosphorylation and activates cytoplasmic substrates such as phosphatidylinositol 3 kinase (PI3K). Phosphorylation of membrane phosphoinositide 2 (PIP2) to phosphoinositide 3 (PIP3) by PI3K starts Akt/PKB activation. Defects in phosphorylation of the insulin receptor and its substrates have an important role in insulin resistance. Studies have shown that insulin resistance is associated with preeclampsia and its pathophysiology. The aim here was to investigate insulin stimulation of the Akt/PKB pathway in the placenta, in normal and preeclampsia parturients. DESIGN AND SETTING Cross-sectional study in a tertiary public university hospital. METHODS Placentas were collected from 12 normal and 12 preeclampsia patients. These were stimulated and analyzed using Western blot to quantify the Akt/PKB phosphorylation. RESULTS The insulin stimulation was confirmed through comparing the stimulated group (1.14 ± 0.10) with the non-stimulated group (0.91 ± 0.08; P < 0.001). The phosphorylation of Akt/PKB did not differ between the placenta of the normal patients (1.26 ± 0.16) and those of the preeclampsia patients (1.01 ± 0.11; P = 0.237). CONCLUSIONS In vitro insulin stimulation of the human placenta has been well established. There was no difference in Akt/PKB phosphorylation, after stimulation with insulin, between placentas of normal and preeclampsia patients. Nevertheless, it cannot be ruled out that the Akt/PKB signaling pathway may have a role in the pathophysiology of preeclampsia, since the substrates of Akt/PKB still need to be investigated.

Abstract
To evaluate the effects of metformin on endometrial stromal cell gene expression and on the decidualization process, endometrial biopsies were collected from five healthy, regularly cycling women. Stromal cell culture was performed and decidualized with oestrogen/progesterone in the presence or absence of metformin and thereafter stimulated with insulin. The effect of metformin on decidualization was analysed by prolactin determination in the cell culture supernatant. Gene expression of insulin-like growth factor binding protein 1 (IGFBP-1), interleukin (IL) 8 and 1β and intercellular adhesion molecule (ICAM) was analysed by real-time PCR. Decidualization was significantly diminished in cells incubated with metformin (P<0.05) accompanied by a significant reduction of prolactin secretion in the supernatant (day 10: 2.2 fold, P<0.05; day 15: 3.1 fold, P<0.05). IGFBP-1 gene expression was reduced after long-term metformin exposure (7.7 fold, P<0.05). The negative effect of insulin on IL-8 (4.8 fold) and IL-1β (9.3 fold) gene expression was similarly found in cells incubated with metformin. As far as is known, this is the first demonstration of a change in endometrial gene and protein expression after in-vitro stimulation with metformin, including a diminished decidualization process and changes in genes relevant to implantation.
