RESUMO

OBJECTIVE: To analyze differences in the menstrual pattern, age at menarche, and body mass index (BMI) in adolescents with Hypothalamic-Pituitary-Ovarian (HPO) axis immaturity and Polycystic Ovary Syndrome (PCOS) through a systematic review and meta-analysis. METHODS: The PubMed, EMBASE, Web of Science, Virtual Health Library, Scopus databases were searched using combinations of descriptors. Study quality was assessed using the Newcastle-Ottawa Scale. For data analysis, the results were grouped into PCOS group and NPCOS group (HPO axis immaturity). We performed a meta-analysis of raw data and the inverse variance method, employing the standardized mean difference, of the age at menarche and BMI of adolescents. RESULTS: Participants totaled 1,718 from nine selected studies. The meta-analysis showed that the PCOS group had a higher BMI than the NPCOS group (SMD 0.334; CI95% 0.073 - 0.595; p = .012). The degree of heterogeneity of the studies was approximately 40%. No significant difference in age at menarche (SMD - 0.027; CI95% -0.227 - 0.172; p = 0.790) and menstrual patterns was found, but amenorrhea was described only in adolescents with PCOS. CONCLUSIONS: The main characteristic in menstrual pattern that differentiated PCOS patients from girls with HPO axis immaturity was amenorrhea. Also, the BMI of PCOS patients was nearly one third higher than that of adolescents with HPO axis immaturity.

RESUMO

OBJECTIVES: This study aimed to evaluate the effects of acupuncture on women with vasomotor symptoms during the menopausal transition with the aid of the Kupperman-Blatt Menopausal Index. METHOD: Crossover, single-blind, sham-controlled trial with 100 women randomly divided into two groups of 50 participants each: G1 and G2. During the first 24 weeks of treatment, the G1 women received acupuncture and the G2 women were given sham acupuncture. The crossover was then applied: the G1 participants were given sham acupuncture, and the G2 participants received acupuncture for 24 more weeks. RESULTS: The mean score of hot flashes of the group who first experienced acupuncture (G1) was statistically higher than that of the group that started with sham acupuncture (G2, P = 0.020). Also, both groups had similar mean scores in the middle of the study (both were receiving acupuncture). During the last 6 months of the study, after crossover, the values of G2 (acupuncture) were lower than those of G1 (sham acupuncture). CONCLUSIONS: Acupuncture treatment may mitigate hot flashes and other climacteric symptoms during the menopausal transition.

RESUMO

Polycystic ovary syndrome (PCOS) is frequently associated with non-alcoholic fatty liver disease (NAFLD), but the mechanisms involved in the development of NAFLD in PCOS are not well known. We investigated histological changes and metabolomic profile in the liver of rat models of PCOS phenotype induced by testosterone or estradiol. Two-day old female rats received sc injections of 1.25 mg testosterone propionate (Testos; n = 10), 0.5 mg estradiol benzoate (E2; n = 10), or vehicle (control group, CNT; n = 10). Animals were euthanized at 90-94 d of age and the liver was harvested for histological and metabolomic analyses. Findings showed only Testos group exhibited fatty liver morphology and higher levels of ketogenic and branched-chain amino acids (BCAA). Enrichment analysis showed effects of testosterone on BCAA degradation pathway and mitochondrial enzymes related to BCAA metabolism. Testos group also had a decreased liver fatty acid elongase 2 (ELOVL2) activity. E2 group had reduced lipid and acylcarnitine metabolites in the liver. Both groups had increased organic cation transporters (SLC22A4 and SLC16A9) activity. These findings indicate that neonatal testosterone treatment, but not estradiol, produces histological changes in female rat liver that mimic NAFLD with testosterone-treated rats showing impaired BCAA metabolism and dysfunctions in ELOVL2, SLC22A4 and SLC16A9 activity.

RESUMO

CONTEXT: Surgery is the main form of treatment for ductal carcinoma in situ (DCIS) of the breast. Among other factors, treatment success requires that the surgical margins are free of disease, to reduce the risk of recurrence. AIMS: The purpose of this study was to analyze factors that might be associated with positive margins in patients diagnosed with DCIS. SETTINGS AND DESIGN: A retrospective analysis was performed of hospital databases from the year 2006 to 2014, to identify patients with an initial diagnosis of DCIS made by percutaneous biopsy. SUBJECTS AND METHODS: Age, the presence of disease symptoms, lesion size on mammogram, and the presence of estrogen receptors, and their relationship to the surgical margins were evaluated in 249 patients. STATISTICAL ANALYSIS USED: Shapiro and Wilcoxon-Mann-Whitney tests were used to verify that the data were normally distributed. Chi-squared test was used to verify the independence of the variables. RESULTS: Lesions measuring 1.55 cm or greater had a relative risk of positive margins after conservative surgery of 1.39 (95% confidence interval [95% CI]: 1.02-1.90). The presence of symptoms had a relative risk of positive margins after conservative surgery of 1.54 (95% CI: 1.17-2.02). CONCLUSION: Lesions measuring 1.55 cm or greater and the presence of symptoms are risk factors for positive margins in the treatment of ductal carcinoma in situ. Therefore, these patients need a better surgical planning in order to reduce the risk of positive margins. There is a clear need for large prospective studies to validate our findings and define other factors that might contribute to the success of surgical resection for ductal carcinoma in situ.

RESUMO

Melatonin has been described as a protective agent against cell death and oxidative stress in different tissues, including in the reproductive system. However, the information on the action of this hormone in rat uterine apoptosis is low. Our objective was to evaluate the effects of melatonin on mechanisms of cell death in uterus of rats exposed to continuous light stress. Twenty adult Wistar rats were divided into two groups: GContr (vehicle control) and GExp which were treated with melatonin (0.4 mg/mL), both were exposed to continuous light for 90 days. The uterus was removed and processed for quantitative real time PCR (qRT-PCR), using PCR-array plates of the apoptosis pathway; for immunohistochemistry and TUNEL. The results of qRT-PCR of GEXP group showed up-regulation of 13 and 7, pro-apoptotic and anti-apoptotic genes, respectively, compared to GContr group. No difference in pro-apoptotic proteins (Bax, Fas and Faslg) expression was observed by immunohistochemistry, although the number of TUNEL-positive cells was lower in the group treated with melatonin compared to the group not treated with this hormone. Our data suggest that melatonin influences the mechanism and decreases the apoptosis in uterus of rats exposed to continuous light.

RESUMO

BACKGROUND: Infertility associated with polycystic ovary syndrome (PCOS) could be related to many mechanisms including endometrial factors. OBJECTIVES: To review cell adhesion molecule and estrogen receptor expression in the endometrium. SEARCH STRATEGY: A systematic review was performed of the Medline and Cochrane databases for papers published in any language between 2004 and 2014. The search term was "'polycystic ovary syndrome' OR 'Stein Leventhal syndrome' OR 'anovulation' AND 'endometrium' OR 'endometria.'" SELECTION CRITERIA: Research studies on endometrial cell adhesion molecules and estrogen receptor expression among women with PCOS diagnosed according to the Rotterdam criteria were included. DATA COLLECTION AND ANALYSIS: Data were extracted from identified studies and the quality of assessment was analyzed. MAIN RESULTS: Six studies were included. Data were controversial with respect to MUC1 and αVß3 integrin expression with significantly higher and lower levels, respectively, in women with PCOS. Estrogen receptor expression was enhanced among patients with PCOS as compared with healthy women. CONCLUSIONS: Endometrial factors influence embryo receptivity as indicated by the molecular mediators identified in the studies, including cell adhesion molecules and the estrogen receptor.

RESUMO

BACKGROUND: Polycystic ovary syndrome (PCOS) is characterized by ovulatory dysfunction and hyperandrogenism. Its etiopathology is not well understood but genetic factors seem to have a role. Polymorphism of the androgen receptor (AR) gene has been associated with different androgen pattern diseases. OBJECTIVE: To review the association between AR gene polymorphism and PCOS. SEARCH STRATEGY: A systematic review was performed via PUBMED, EMBASE, and LILACS (up to May 31, 2011). SELECTION CRITERIA: Studies assessing the presence of the (CAG)(n) polymorphism of the AR gene in at least 2 comparison groups (PCOS and control). Studies that did not contain adequate information were excluded. DATA COLLECTION AND ANALYSIS: Study characteristics and results were analyzed. Meta-analysis could not be performed because only 2 articles provided odds ratios. MAIN RESULTS: Ten studies met the inclusion criteria. Three studies reported a correlation between the polymorphism and PCOS; 2 studies linked the disorder to shorter repeats, whereas the other associated it with longer repeats. CONCLUSION: Polymorphism of the AR gene seems to be a promising biomarker for PCOS because shorter repeats may be linked to the disorder. However, further studies are needed to understand the association fully.

RESUMO

OBJECTIVE: The aim of this study was to construct and to validate a measure of the consequences of domestic violence on women's health during climacterium. METHODS: A questionnaire was administered at the Outpatient Climacterium Clinic to 124 women aged 40 to 65 years who were the victims of domestic and/or sexual violence (experimental group). They were divided into three groups: (1) those who were victims of violence exclusively during childhood/adolescence, (2) those who were victims of violence exclusively during adulthood, and (3) those who were victims of violence throughout their lives. The instrument included 34 items evaluating the beginning, frequency, and type of violence; the search for health assistance and reporting of the violence; the violence and the number of comorbidities; and violence and the Kupperman Menopausal Index. We also included a control group composed of perimenopausal and postmenopausal women who did not experience any violence (n = 120). RESULTS: The instrument presented a Cronbach α = 0.82, good reliability among the examiners (+0.80), and a good possibility of reproducibility. The mean age of menopause was 45.4 years, and the mean age in the control group was 48.1 years. Group 1 showed a mean of 5.1 comorbidities, Group 2 had 4.6, and Group 3 had 4.4. Sexual violence (43.5%) and other types of violence both presented average comorbidities (4.60) but represented a significant impairment in the victim's sexual life. There were significant associations in group 3 and a high Kupperman Menopausal Index score. In the experimental group, 80.6% did not seek health services for the violence they experienced. CONCLUSIONS: The questionnaire presented good internal consistency and a validated construction. It can be easily reproduced and is indicated to evaluate the consequences of domestic and/or sexual violence on women's health during climacterium.

RESUMO

OBJECTIVE: To develop an animal model of endometrial ablation, and to evaluate the histologic effects of trichloroacetic acid (TCA) in the uterine cavity. DESIGN: Experimental prospective. SETTING: Department of gynecology. PATIENT(S): Thirty female adult rats. INTERVENTION(S): Animals were submitted to injection of TCA in one uterine horn and saline solution in the other. Group 1 was sacrificed the day after the procedure. Group 2 was sacrificed in phase of diestrus. Superficial epithelia of the endometrium, stromal thickness, endometrial glands, and myometrium thickness were compared among the uterine horns of the same rats of group 1. The same evaluation was performed in group 2. Endometrial regeneration was evaluated. MAIN OUTCOME MEASURE(S): Histologic effects. RESULT(S): In group 1, histologic parameters showed endometrial destruction on TCA injected uterine horn. In group 2, four rats died after the procedure, and six rats had no viable material. In the rest of the group, TCA-injected uterine horns showed endometrial destruction. Superficial epithelia of the endometrium and stromal thickness were similar between TCA uterine horn from groups. However, the number of endometrial glands was higher in group 1. CONCLUSION(S): The study developed an experimental model for endometrial ablation. TCA acid is a potent agent for endometrial ablation in rat model. No endometrial regeneration was observed after recovery of cycle.
