RESUMO
PURPOSE: Adenomyosis has been studied throughout the years, however, its aetiology and physiopathology are still unknown. The aim of this study was to identify the presence of PIWI proteins in women with adenomyosis. METHODS: We included 72 participants to be part of this study and were divided into two groups based on their anatomopathological diagnosis, control (n = 36) or adenomyosis (n = 36). All samples were tested for PIWIL1, PIWIL2 and PIWIL4 proteins by immunohistochemistry. The evaluation of protein expression was performed by the digital histological score (DHSCORE) and by the pathologist's analysis. RESULTS: The participants had a mean age of 44.28 ± 5.76 years and 45.81 ± 4.86 years in the control and adenomyosis groups, respectively (p ≥ 0.05). Other clinical characteristics of the participants showed no statistical difference as well. PIWIL2 is highly expressed in the adenomyosis in comparison to the control group (p = 0.0001). The PIWIL1 is downregulated in the adenomyosis (p = 0.003) and PIWIL4 showed no difference in its expression (p = 0.05). CONCLUSION: PIWIL2 might be involved in cellular survival and PIWIL1 may be downregulated due to the loss of tissue's function and response to the hostile environment of the myometrium. This is the first time that PIWI proteins are studied in the adenomyosis.

Objective: Pregnancy complicated by type 2 diabetes is rising, while data on type 2 diabetes first diagnosed in pregnancy (overt diabetes) are scarce. We aimed to describe the frequency and characteristics of pregnant women with overt diabetes, compare them to those with known pregestational diabetes, and evaluate the potential predictors for the diagnosis of overt diabetes. Subjects and methods: A retrospective cohort study including all pregnant women with type 2 diabetes evaluated in two public hospitals in Porto Alegre, Brazil, from May 20, 2005, to June 30, 2021. Classic and obstetric factors associated with type 2 diabetes risk were compared between the two groups, using machine learning techniques and multivariable analysis with Poisson regression. Results: Overt diabetes occurred in 33% (95% confidence interval: 29%-37%) of 646 women. Characteristics of women with known or unknown type 2 diabetes were similar; excessive weight was the most common risk factor, affecting ~90% of women. Age >30 years and positive family history of diabetes were inversely related to a diagnosis of overt diabetes, while previous delivery of a macrosomic baby behaved as a risk factor in younger multiparous women; previous gestational diabetes and chronic hypertension were not relevant risk factors. Conclusion: Characteristics of women with overt diabetes are similar to those of women with pregestational diabetes. Classic risk factors for diabetes not included in current questionnaires can help identify women at risk of type 2 diabetes before they become pregnant.

OBJECTIVE: Endometriosis is associated with infertility, even without an anatomical abnormality. Furthermore, the peritoneal (mild) phenotype of this disease is the most prevalent and linked to infertility. The present study aimed to investigate the p63 gene and protein expression in granulosa cells from pre-ovulatory follicles in patients with endometriosis and infertility submitted to in vitro fertilization. METHODS: Twenty-eight patients participated in the study and were divided into two groups according to the presence or absence of endometriosis. The p63 gene-expression levels assessment was performed by real-time PCR (qPCR) using the TaqMan assay, and we used immunofluorescence to check the p63 protein expression after IVF. RESULTS: There was no significant difference between the groups regarding age, hormonal levels, oocyte standards, and p63 gene expression. The control group showed an RQ of 1.000 (0.431 to 2.323) and the study group showed an RQ of 0.725 (0.249 to 2.105), p>0.05. Both groups showed a weak expression of the p63 gene (p>0.05). CONCLUSIONS: This study described that endometriosis may not affect the p63 gene expression. Moreover, after follicular recruitment and growth, we found a weak expression of this protein, suggesting it is not part of oocyte maturation and development control.

BACKGROUND: During the COVID-19 pandemic, some studies describing different aspects of the infection included very similar participants, rising suspicion about double reporting. We aimed to evaluate the Gantt chart as a tool to highlight possible double reporting. The chart is routinely used in business applications to depict tasks of a project, by plotting horizontal bars against time, showing their time span and overlaps. METHODS: All case reports and case series of pregnant women with COVID-19, published by July 15, 2020, were included. Initial and final dates of participants' enrollment, country, city, hospital, and number of pregnancies were plotted in the Gantt chart. Bars stand for enrollment dates of each study, according to hospital and city, thus allowing comparisons. RESULTS: We included 116 articles in the present analysis. The Gantt chart highlighted papers in which some participants were likely the same, thus allowing easier identification of double reporting of cases. Combining all information and pregnancy characteristics and outcomes helped to recognize duplications when the authors did not acknowledged the previous publication. CONCLUSIONS: Unintended double reporting may occur, especially in exceptional times. The Gantt chart may help researchers to visually identify potential duplications, thus avoiding biased estimates in systematic reviews or meta-analysis.

BACKGROUND: Pain is strongly related to poor quality of life. We performed a cross-sectional study in a university hospital to investigate quality of life in women suffering from chronic pelvic pain (CPP) due to endometriosis and others conditions. METHODS: Fifty-seven patients aged between 25 and 48 years-old submitted to laparoscopy because of CPP were evaluated for quality of life and depressive symptoms. Quality of life was accessed by a quality of life instrument [World Health Organization Quality of Life Assessment-Bref (WHOQOL-bref)]. Causes of pelvic pain were determined and severity of CPP was measured with a visual analogue scale. According to the intensity of pelvic pain score, patients were classified in two groups (group Low CPP < 25th percentile visual analogue scale and group High CPP > 25th percentile). Four dimensions on quality of life were measured (physical, psychological, social and environmental). We stratified the analysis of quality of life according CPP causes (presence or not of endometriosis in laparoscopy). RESULTS: Patients with higher pain scores presented lower quality of life status in psychological and environmental dimensions. We found a negative correlation between pain scores and psychological dimension of quality of life (r = -0.310, P = .02). Quality of life scores were similar between groups with and without endometriosis (physical 54.2 ± 12.8 and 51.1 ± 13.8, P = 0.504; psychological 56.2 ± 14.4 and 62.8 ± 12.4, P = 0.182; social 55.6 ± 18.2 and 62.1 ± 19.1, P = 0.325; environmental 59.2 ± 11.7 61.2 ± 10.8, P = 0.608; respectively) CONCLUSIONS: Higher pain scores are correlated to lower quality of life; however the fact of having endometriosis in addition to CPP does not have an additional impact upon the quality of life.

BACKGROUND: Previous studies have associated chronic pelvic pain with a stereotyped pattern of movement and posture, lack of normal body sensations, a characteristic pain distribution. We aimed at evaluating if these postural changes are detectable in baropodometry results in patients with chronic pelvic pain. METHODS: We performed a prospective study in a university hospital. We selected 32 patients suffering from chronic pelvic pain (study group) and 30 women without this pathology (regular gynecological work out--control group). Pain scores and baropodometric analysis were performed. RESULTS: As expected, study group presented higher pain scores than control group. Study and control groups presented similar averages for the maximum pressures to the left and right soles as well as soles supports in the forefeet and hind feet. Women suffering from chronic pelvic pain did not present differences in baropodometric analysis when compared to healthy controls. CONCLUSIONS: This data demonstrates that postural abnormalities resulting from CPP could not be demonstrated by baropodometric evaluation. Other postural measures should be addressed to evaluate pelvic pain patients.

PURPOSE: We conducted a cross-sectional study to evaluate the linkage of FSHR T307A and N680S in a group of fertile women. METHODS: Peripheral blood was obtained from 51 fertile women. DNA extraction and isolation were performed. For the detection of the T307A polymorphism a set of primers (5_-TCTGAGCTTCATCCAATTTGCA-3_and 5_-GGGAAAGAGGGCA GCTGCAA-3) was used and then the product was further amplified by a second PCR-RFLP using another set of primers (5_-CAAATCTATTTTAAGGCAAGAAGTTGATTATATGCCTCAG-3_and 5_-GTAGATTCCAATGCAGA GATCA-3). For the N680S polymorphism the primers (5_-TTTGTGGTCATCTGTGGCTGC-3_ and 5_-CAAAGGCAAGGACTGAATT ATC ATT-3_) were used. Statistical analysis for the association between the polymorphisms was performed by the Spearman test. RESULTS: We calculated the association between the homozygosis at codon 307 and at codon 680 both for T/T-S/S and A/A-N/N. A significant association between the genotypic results at codon 680 with those at codon 307 was found (r = 0.6363, P = 0.001). However, a complete linkage between these two polymorphisms was rejected as there were 12 patients with discordant results from the expected A-N/T-S at codons 307 and 680, respectively. CONCLUSION: The current data demonstrated an association but failed to demonstrate a complete linkage between these two polymorphisms.

BACKGROUND: Some maternal characteristics indicate worse prognosis in pregnant women with coronavirus disease 2019 (COVID-19). OBJECTIVE: To describe the prevalence of endocrine disorders in pregnancies involving COVID-19, and its impact on maternal outcomes. SEARCH STRATEGY: Search terms were "pregnancy" and "COVID-19". SELECTION: PubMed, Embase, medRxiv, and Cochrane worksheet from February to July 2020 were searched. DATA COLLECTION AND ANALYSIS: Articles describing endocrine disorders in pregnancies with and without COVID-19 involvement were considered. We performed meta-analyses of prevalence using random-effect models and estimated relative risk and 95% confidence intervals (CI) of maternal outcomes relative to presence of endocrine disorders. MAIN RESULTS: Articles included (n = 141) were divided into three data sets: individual (119 articles, 356 women), case series (17 articles, 1064 women), and national registries (7 articles, 10 178 women). Prevalence of obesity ranged from 16% to 46% and hyperglycemia in pregnancy (HIP) ranged from 8% to 12%. In data set 1, HIP and obesity were risk factors for severe disease in crude and age-adjusted models, although not for intensive care unit admission. In data from two national registries, risk of dying was 5.62 (95% CI 0.30-105.95) in women with diabetes and 2.26 (95% CI 1.03-4.96) in those with obesity. CONCLUSION: Obesity and HIP were prevalent in pregnant women with severe COVID-19.

OBJECTIVE: to compare the effect of administering diclofenac sodium and/or oral hyoscine in pain perception during and after outpatient diagnostic hysteroscopy without anesthesia. STUDY DESIGN: a randomized, double-blind placebo-controlled clinical trial was performed in an University Hospital. We included 217 patients submitted to office hysteroscopy for the following indications: diagnosis of abnormal uterine bleeding, endometrial polyps, submucous myomas, infertility and recurrent miscarriage. Patients were allocated into 3 groups: (Group 1) placebo, (Group 2) diclofenac sodium 50 mg and (Group 3) diclofenac sodium 50 mg plus Hyoscine-N-Butylbromide 10 mg. The primary outcome was the visual analogue score immediately after the procedure. The secondary outcomes included Likert acceptance scale, the need for extra analgesia after the procedure, need to stay in the observation room and the occurrence of vagal symptoms. RESULTS: Groups were similar according to age, color, age of menarche, gravity, c-section, abortion, presence of pelvic pain, presence of uterine scar, height and body mass index. Patients in all three groups demonstrated similar visual pain scores when submitted to office hysteroscopy (Group 1: 4.18 ± 3.1, Group 2: 4.68 ± 2.9, group 3: 4.45 ± 2.9, P = 0.59). Moreover, patients presented high acceptance scores of the procedure, similar between groups. We performed a subgroup analysis in patients in treatment for chronic pelvic pain and, in this subgroup, prior medication with diclofenac sodium isolated or associated with hyoscine were both effective in decreasing pain levels when compared to placebo (Group 1: 6.0 ± 1.9, Group 2: 3.6 ± 2.1, group 3: 4.2 ± 1.5, P = 0.04). CONCLUSION(S): Office hysteroscopy is a well tolerated procedure and prior use of analgesic medication was not effective in decreasing pain. In selected patients with chronic pelvic pain the use prior analgesic medication may be beneficial.

OBJECTIVE: To investigate the correlation between the numerical rating scale, visual analogue scale, and pressure threshold by algometry in women with chronic pelvic pain. STUDY DESIGN: This was a cross-sectional study. We included 47 patients with chronic pelvic pain. All subjects underwent a pain assessment that used three different methods and were divided according to the cause of pain (endometriosis versus non-endometriosis). Moreover, we assessed the agreement between the scales (visual, analogue and algometry) using the intraclass correlation coefficient (ICC). RESULTS: The ICC for the numeric rating scale and the visual analogue scale regarding pain (0.992), dysmenorrhea (1.00) and dyspareunia (0.996) were strong. The agreement between the scales was excellent (p ≤0.01). The correlation between algometry and the scales showed a moderate and inverse association, and this correlation was statistically significant: as the scores on the numeric rating scale and the visual analogue scale regarding dyspareunia increased, the algometry thresholds decreased. CONCLUSIONS: The assessment of women with chronic pelvic pain should combine pressure algometry and the numeric rating scale or the visual analogue scale, because of their inverse correlations and satisfactory reliability and sensitivity, to make pain assessment less subjective and more accurate.

RESUMO
OBJECTIVES: To compare reproductive outcomes using two different soft catheters i.e. Set TDT® and Cook® Sydney IVF. The primary outcome was defined as a positive ß-human chorionic gonadotropin (ß-hCG) test. METHODS: Our prospective study recruited 68 patients undergoing in vitro fertilization cycles in a private fertility clinic in Porto Alegre, Brazil, between January 2014 and April 2016. They were divided into two groups according to the catheter that would be used for the embryo transfer, and the groups were matched by age. The total number of patients in each group was: 34 for the TDT and 34 for the Cook Sydney. All the patients were submitted to a ß-hCG test 12 days after the embryo transfer for pregnancy outcome evaluation. RESULTS: Ten out of 34 patients from the TDT group had a positive outcome for pregnancy, corresponding to 29.4%. The Cook Sydney group had 9 patients out of 34 with positive outcomes, corresponding to 26.5%. Comparing the efficacy of both catheters for the primary outcome, there was no significant difference (p>0.05) between the TDT and the Cook Sydney catheters. CONCLUSION: The TDT and the Cook Sydney catheters efficacies were similar for embryo transfer during assisted reproductive technology cycles.
