RESUMO
Kogure, GS, Silva, RC, Miranda-Furtado, CL, Ribeiro, VB, Pedroso, DCC, Melo, AS, Ferriani, RA, and Reis, RMd. Hyperandrogenism enhances muscle strength after progressive resistance training, independent of body composition, in women with polycystic ovary syndrome. J Strength Cond Res 32(9): 2651-2660, 2018-The effects of resistance exercise on muscle strength, body composition, and increase in cross-sectional area of skeletal muscle (hypertrophy) were evaluated in women with polycystic ovary syndrome (PCOS). This case-control study included 45 PCOS and 52 non-PCOS women, with age between 18-37 years and body mass index of 18-39.9 kg·m. Subjects performed a program of progressive resistance training (PRT), 3 times per week for 4 months. Biochemical characteristics were measured before and after PRT. Muscle strength evaluated by 1 maximum repetition test and body composition and hypertrophy indicator, evaluated by anthropometry, were measured at baseline, at 8 weeks, and at 16 weeks after PRT. Progressive resistance training produced an increase in maximum strength (bench press, p = 0.04; leg extension, p = 0.04) in the PCOS group; however, no changes were observed in body composition between groups. Concentration of testosterone decreased in both PCOS and non-PCOS groups (p < 0.01, both) after PRT, as well as glycemia (PCOS, p = 0.01; non-PCOS, p = 0.02) and body fat percentage (p < 0.01, both). An increase in hypertrophy indicators, lean body mass (LBM), and maximum strength on all exercises was observed in both PCOS and non-PCOS groups (p < 0.01). This training protocol promoted increases in muscle strength in PCOS women, and improved hyperandrogenism and body composition by decreasing body fat and increasing LBM and muscle strength in both PCOS and non-PCOS groups. Therefore, it is suggested that resistance exercise programs could promote health and fitness in women of reproductive age, especially functional capacity of strength those with PCOS.

BACKGROUND: Uterine leiomyoma is the most common gynecological tumor in the reproductive years. However, it is extremely rare in adolescence (<1%), with few reports found in the literature. The biological behavior of such tumors in this age group is unknown, as well as the best possible treatment for this population. We aimed to analyze all available reports of uterine leiomyoma in adolescence. METHODS: A systematic review was performed at PubMed/MEDLINE and EMBASE. Between 1965 and 2014, 19 reports were found on uterine leiomyoma in patients under 18 years. The following parameters were discussed: age, tumor diameter, symptoms, clinical treatments, surgical treatments, hemodynamic changes. RESULTS: Mean age was 15.35 (14-17) years. Mean tumor diameter was 12.28 cm (3-30) and median diameter was 10 cm. Most patients presented with symptoms (87.5%), including abnormal uterine bleeding (10/18) and pelvic/abdominal pain (6/18). A pelvic mass was the most common finding. Two patients required transfusion due to anemia. One patient underwent abdominal hysterectomy, and the others underwent myomectomy. Mean follow-up was 1 year and 8 months, and only case recurred, after 6 months. CONCLUSION: Leiomyomas' biologic behavior in adolescents may be different from that of older women, but their molecular characteristics still haven't been analyzed. Optimal treatment is still not defined, but myomectomy has several advantages in this population. Leiomyomas must be remembered as an important differential diagnosis of pelvic mass in adolescents.

OBJECTIVE: To evaluate the impact of possible maternal and paternal prognostic factors and ovarian stimulation protocols on clinical pregnancy and live birth rates in intrauterine insemination (IUI) cycles. METHODS: Retrospective observational study of 341 IUI cycles performed from January 2016 to November 2020 at the Assisted Reproduction Service of the Clinics Hospital of the Ribeirão Preto Medical School, University of São Paulo. Clinical pregnancy and live birth rates and their potential prognostic factors were evaluated. Wilcoxon's non-parametric test was used to compare quantitative variables, and the chi-square test to compare qualitative variables, adopting a significance level of p<0.05. A logistic regression model was performed to verify which exploratory variables are predictive factors for pregnancy outcome. RESULTS: The ovulation induction protocol using gonadotropins plus letrozole (p=0.0097; OR 4.3286, CI 1.3040 - 14.3684) and post-capacitation progressive sperm ≥ 5million/mL (p=0.0253) showed a statistically significant correlation with the live birth rate. Female and male age, etiology of infertility, obesity, multifollicular growth, endometrial thickness ≥ 7 mm, and time between human chorionic gonadotropin administration and IUI performance were not associated with the primary outcomes. In the group of patients with ideal characteristics (women aged< 40 years, BMI < 30 kg/m2, antral follicle count ≥ 5, partner aged< 45 years, and post-capacitation semen with progressive spermatozoa ≥ 5 million/mL), the rate of clinical pregnancy was 14.8%, while that of live birth, 9.9%. CONCLUSIONS: In this study, the ovulation induction protocol with gonadotropins plus letrozole and post-capacitation progressive sperm ≥ 5 million/mL were the only variables that significantly correlated with intrauterine insemination success.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders, affecting approximately 5-20% of women of reproductive age. PCOS is a multifactorial, complex, and heterogeneous disease, characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries, which may lead to impaired fertility. Besides the reproductive outcomes, multiple comorbidities, such as metabolic disturbances, insulin resistance, obesity, diabetes, and cardiovascular disease, are associated with PCOS. In addition to the clear genetic basis, epigenetic alterations may also play a central role in PCOS outcomes, as environmental and hormonal alterations directly affect clinical manifestations and PCOS development. Here, we highlighted the epigenetic modifications in the multiplicity of clinical manifestations, as well as environmental epigenetic disruptors, as intrauterine hormonal and metabolic alterations affecting embryo development and the adulthood lifestyle, which may contribute to PCOS development. Additionally, we also discussed the new approaches for future studies and potential epigenetic biomarkers for the treatment of associated comorbidities and improvement in quality of life of women with PCOS.

Metabolic and hormonal outcomes of polycystic ovary syndrome (PCOS) have implications on telomere biology and physical activity may prevent telomere erosion. We sought to observe the effects of continuous (CAT) and intermittent (IAT) aerobic training on telomere length, inflammatory biomarkers, and its correlation with metabolic, hormonal, and anthropometric parameters of PCOS. This randomized controlled clinical trial study included 87 PCOS randomly stratified according to body mass index (BMI) in CAT (n = 28), IAT (n = 29) and non-training control group (CG, n = 30). The exercises were carried out on a treadmill, three times per week for 16 weeks. The participants' anthropometric characteristics and biochemical and hormonal concentrations were measured before and after aerobic training or observation period, as the telomere length that was evaluated using quantitative real-time PCR. Four months of aerobic exercises (CAT or IAT) did not alter telomere length and inflammatory biomarkers in PCOS women. Obesity index as BMI and waist circumference (WC), and inflammatory biomarkers negatively affect telomeres. The hyper-andro-genism measured by testosterone levels was reduced after both exercises (CAT, p ≤ 0.001; IAT, p = 0.019). In particular, the CAT reduced WC (p = 0.045), hip circumference (p = 0.032), serum cholesterol (p ≤ 0.001), and low-density lipoprotein (p = 0.030). Whereas, the IAT decreased WC (p = 0.014), waist-to-hip ratio (p = 0.012), free androgen index (FAI) (p = 0.037). WC (p = 0.049) and body fat (p = 0.015) increased in the non-training group while total cholesterol was reduced (p = 0.010). Booth exercises reduced obesity indices and hyperandrogenism on PCOS women without changes in telomere length or inflammatory biomarkers.

OBJECTIVE: The present study aimed to analyze cardiac autonomic modulation via spectral and symbolic analysis of heart rate variability (HRV) in women with polycystic ovary syndrome (PCOS) who were subjected to two consecutive tilt tests. METHODS: A total of 64 women were selected and divided into 2 groups: control (without PCOS), and PCOS. Concentrations of follicle-stimulating hormone, luteinizing hormone, prolactin, estradiol, homocysteine, sex hormone-binding globulin, thyroid stimulating hormone, fasting insulin, testosterone, androstenedione, and 17-hydroxyprogesterone levels, triglycerides, free androgen index (FAI), and homeostasis assessment model (HOMA-IR) were assessed. Cardiac autonomic modulation was evaluated by spectral and symbolic analyses during two consecutive tilt tests (two moments) and supine moments before, between and after (three moments) the tilt tests. RESULTS: Women with PCOS had higher fasting insulin, HOMA-IR indexes, testosterone and FAI. Additionally, we observed that the PCOS group had greater sympathetic autonomic cardiac modulation in supine 2, tilt 1, and supine 3 moments compared with controls. CONCLUSION: Women with PCOS had higher autonomic sympathetic cardiac modulation even after a second tilt test. No adaptation to this provocative test was observed. Spectral analysis was more sensitive for identifying differences between groups than the symbolic analysis.
OBJETIVO: O presente estudo teve como objetivo analisar a modulação autonômica cardíaca por análise espectral e simbólica da variabilidade da frequência cardíaca (VFC) em mulheres com síndrome dos ovários policísticos (SOP) que foram submetidas a dois testes consecutivos de inclinação. MéTODOS: Um total de 64 mulheres foram selecionadas e divididas em 2 grupos: controle (sem SOP) e SOP. Concentrações de hormônio folículo-estimulante, hormônio luteinizante, prolactina, estradiol, homocisteína, globulina de ligação a hormônios sexuais, hormônio estimulante da tireóide, insulina em jejum, testosterona e androstenediona e níveis de 17-hidroxiprogesterona, triglicerídeos, índice de andrógeno livre (FAI) e homeostase modelo de avaliação (HOMA-IR) foram avaliados. A modulação autonômica cardíaca foi avaliada por análises espectrais e simbólicas durante dois testes de inclinação consecutivos (dois momentos) e momentos supinos antes, entre e após (três momentos) os testes de inclinação. RESULTADOS: Mulheres com SOP apresentaram insulina em jejuM, índices HOMA-IR, testosterona e FAI mais altos. Além disso, observamos que o grupo PCOS apresentou maior modulação cardíaca autonômica simpática nos momentos supino 2, inclinado 1 e supino 3 em comparação aos controles. CONCLUSãO: Mulheres com SOP apresentaram modulação cardíaca simpática autonômica mais alta mesmo após um segundo teste de inclinação. Nenhuma adaptação a esse teste provocativo foi observada. A análise espectral foi mais sensível para identificar diferenças entre os grupos do que a análise simbólica.

OBJECTIVE: To study the global DNA methylation pattern in spermatozoa of patients with varicocele as well as investigate their semen quality. DESIGN: Prospective observational case-control study. SETTING: University-affiliated hospital. PATIENT(S): A total of 26 men with varicocele and 26 fertile men without the disorder. INTERVENTIONS: Analysis of semen quality and sperm DNA methylation patterns. MAIN OUTCOME MEASURE(S): Semen quality evaluated by semen analysis, and sperm DNA methylation patterns investigated using the Infinium MethylationEPIC BeadChip platform. RESULT(S): Men with varicocele displayed decreased semen quality. The sperm DNA methylation analysis showed that men with varicocele exhibit global hypomethylation in comparison with the control group. A total of 59 differentially methylated CpG sites were identified, most of them hypomethylated in the varicocele group. In regional analyses, 1,695 DNA regions were differentially methylated in men with varicocele. These regions show associations with gamete generation, meiotic and meiosis cell cycle, and semen quality based on gene ontology analysis. CONCLUSION(S): Gene ontology results suggest that changes in methylation may be associated with the low semen quality phenotype observed in some varicocele patients because the observed differentially methylated regions in varicocele patients are related to male reproductive pathways. Additionally, the varicocele grade may influence the magnitude of global sperm DNA methylation change. To our knowledge, this is the first report analyzing changes at a regional or CpG-specific level in men with varicocele.

Adolescence is characterized by significant biological and psychological changes. During this time, the increased production of androgens leads to increased sexual behavior, and this may contribute to early initiation of sexual activity. The objectives of the present cross-sectional study of adolescents enrolled in state schools in the city of Ribeirão Preto, state of São Paulo, Brazil, were to determine the average age at the first sexual intercourse (sexarche), the average number of sexual partners, and the frequency of contraceptive and condom use. Information on the age at sexarche, number of sexual partners, use of different contraceptive methods, and use of condoms were obtained using a semistructured questionnaire. Quantitative variables are expressed as means and standard deviations (SDs), and qualitative variables as absolute and relative frequencies. The chi-squared test was used for comparisons of qualitative variables, and the Student t-test for comparisons of continuous variables. All statistical analyses were performed using SAS (version 9.4, North Carolina State University, USA). We evaluated 202 students who answered the questionnaire, 69 males (36.36%) and 133 females (63.64%). The age at sexarche for men ranged from 7 to 18 years old, and for women from 7 to 17 years old. Forty-eight girls (36.01%) and 21 boys (30.43%) were in the first year of high school, 66.94% of adolescents reported sexual intercourse, and 56.25% used a condom during the first sexual intercourse. A total of 36.72% of students said they had safe sex most of the time, and 83.59% said that the first sexual intercourse happened because they "had a crush on" the other person.
A adolescência é caracterizada por significativas mudanças biológicas e psicológicas. Durante esse período, o aumento da produção de andrógenos leva ao aumento do comportamento sexual e isso pode contribuir para o início precoce da atividade sexual. Os objetivos do presente estudo transversal de adolescentes matriculados em escolas estaduais da cidade de Ribeirão Preto, São Paulo, Brasil, foram determinar a idade média na primeira relação sexual (sexarca), o número médio de parceiros sexuais e a frequência de uso de contraceptivos e preservativos. Informações sobre idade na sexarca, número de parceiros sexuais, uso de diferentes métodos contraceptivos e uso de preservativo foram obtidas por meio de um questionário semiestruturado. As variáveis quantitativas são expressas como média e desvio padrão (DP) e as variáveis qualitativas como frequências absolutas e relativas. O teste do qui-quadrado foi usado para comparações de variáveis qualitativas e o teste t de Student para comparações de variáveis contínuas. Todas as análises estatísticas foram realizadas no SAS (version 9.4, North Carolina State University, USA). Foram avaliados 202 estudantes que responderam ao questionário, 69 do sexo masculino (36,36%) e 133 do feminino (63,64%). A idade de sexarca para homens variou de 7 a 18 anos e para mulheres de 7 a 17 anos. Quarenta e oito meninas (36,01%) e 21 meninos (30,43%) cursavam o primeiro ano do ensino médio, 66,94% dos adolescentes relataram relações sexuais e 56,25% usaram camisinha durante a primeira relação sexual. Um total de 36,72% dos estudantes afirmou ter praticado sexo seguro a maior parte do tempo e 83,59% disseram que a primeira relação sexual aconteceu porque "tinham uma queda por" a outra pessoa.

OBJECTIVE: The present study aimed to investigate the physical performance of handgrip strength (HGS) in women with polycystic ovary syndrome (PCOS). METHODS: A case-control study that included 70 women with PCOS and 93 age-matched healthy women aged between 18 and 47 years with body mass index (BMI) between 18 Kg/m2-39.9 Kg/m2. The serum levels of total testosterone, androstenedione, insulin, estradiol, thyroid-stimulating hormone (TSH), prolactin, sex hormone-binding globulin (SHBG), and 17-hydroxyprogesterone (17-OHP) were measured. The free androgen index (FAI) and the homeostatic model assessment of insulin resistance (HOMA-IR) were calculated. The body composition regions of interest (ROIs) were assessed by dual-energy X-ray absorptiometry (DXA), and the handgrip strength (HGS) was evaluated for both the dominant and the non-dominant hands with a manual Sammons Preston (Bolingbrook, IL, US) bulb dynamometer. RESULTS: Women with PCOS had high serum levels of total testosterone (p < 0.01), androstenedione (p = 0.03), and insulin (p < 0.01), as well as high FAI (p < 0.01) and HOMA-IR (p = 0.01) scores. Compared with the non-PCOS group, the PCOS group had greater total lean mass in the dominant hand (p < 0.03) and greater HGS in both the dominant and the non-dominant hands (p < 0.01). The HGS was correlated with lean mass (p < 0.01). CONCLUSION: Women with PCOS have greater HGS. This may be associated with age and BMI, and it may be related to lean mass. In addition, the dominance effect on muscle mass may influence the physical performance regarding HGS in women with PCOS.
OBJETIVO: O objetivo deste estudo foi avaliar a força de preensão manual (FPM) em mulheres com síndrome dos ovários policísticos (SOP). MéTODOS: Estudo de caso-controle que incluiu 70 mulheres com SOP e 93 mulheres saudáveis com idade entre 18 e 47 anos e índice de massa corporal (IMC) de 18 Kg/m2 a 39.9 Kg/m2. Foram dosados os níveis séricos de testosterona total, androstenediona, insulina, estradiol, hormônio estimulador da tireoide (HET), prolactina, globulina de ligação ao hormônio sexual (GLHS), e 17-hidroxiprogesterona (17-OHP). Foram calculados o índice de androgênio livre (IAL) e a avaliação do modelo homeostático da resistência à insulina (AMH-RI). As regiões de interesse (RIs) da composição corporal foram avaliadas por absorciometria de raios-x de dupla energia (ARDE), e a força de preensão manual (FPM) das mãos dominante e não dominante foi avaliada com um dinamômetro manual Sammons Preston (Bolingbrook, IL, EUA). RESULTADOS: Mulheres com SOP apresentaram níveis séricos elevados de testosterona total (p < 0.01), androstenediona (p = 0.03), e insulina (P < 0.01), assim como valores altos no IAL (p < 0.01) e no AMH-RI (p = 0.01). Comparado ao grupo controle, o grupo SOP apresentou maior massa magra total na mão dominante (p < 0.03) e maior FPM em ambas as mãos (p < 0.01). A FPM foi correlacionada com a massa muscular magra (p <0.01). CONCLUSãO: Mulheres com SOP têm maior FPM, que pode estar associada à idade, ao IMC, e à massa magra. Além disso, o efeito de dominância na massa muscular pode influenciar o desempenho físico na força de preensão manual em mulheres com SOP.

OBJECTIVE: To assess the utility of bioimpedance (BIA) and skinfolds thickness (SF) in body fat percentage measuring (%BF) compared to the reference method dual-energy x-ray absorptiometry (DXA) in Brazilian reproductive age women, as well as to estimate of inter- and intra-observer precision for SF. SUBJECTS AND METHODS: 170 women aged 18-37 years with BMI between 18 and 39.9 kg/m2 were selected for this cross-sectional study. Body density was evaluated through equations proposed by Jackson, Pollock and Ward (1980) (EqJPW) and Petroski (1995) (EqPET), and %BF was estimated by BIA, DXA and Siri's formula (1961). The SF were measured by two separate observers: A and B (to determine inter-observer variability), who measured the folds at three times with 10-minute interval between them (to determine intra-observer variability - we used only observer A). RESULTS: The %BF by DXA was higher than those measured by SF and BIA (p<0.01, for all) of 90 volunteers. The Lin coefficient of agreement was considered satisfactory for %BF values obtained by EqJPW and BIA (0.55) and moderate (0.76) for sum of SF (ΣSF) values obtained by EqJPW and EqPET. No agreement was observed for the values obtained by SF (EqJPW and EqPET), BIA and DXA. Analysis of inter- and intra-observer of 59 volunteers showed that different measures of SF thickness met acceptability standards, as well as the % BF. CONCLUSION: BIA and SF measurements may underestimate %BF compared with DXA. In addition, BIA and SF measurements are not interchangeable with DXA. However, our results suggest the equation proposed by Jackson, Pollock and Ward (three skinfolds) compared to BIA are interchangeable to quantify the %BF in Brazilian women in reproductive age. Furthermore, our results show acceptable accuracy for intra- and inter-observer skinfold measurements. Arch Endocrinol Metab. 2020;64(3):257-68.

BACKGROUND: Both physical and mental health care for women with polycystic ovary syndrome (PCOS) require a multidisciplinary approach. We evaluated the effects of continuous (CAT) and intermittent (IAT) aerobic training in different protocols that measure body image, anxiety, depression and sexual dysfunction in women with PCOS. METHODS: In this controlled clinical trial, women with PCOS were randomly allocated for 16 weeks to 1 out of 3 groups: CAT (nâ¯=â¯28), IAT (nâ¯=â¯29), or control group (CG, nâ¯=â¯30). For data collection, we used the Body Shape Questionnaire (BSQ), Figure Rating Scale (FRS), Female Sexual Function Index (FSFI), Hospital Anxiety and Depression Measurement Scales (HADS). RESULTS: No effects of CAT, IAT or CG groups were identified in the perceptual dimension of body image. The dis(satisfaction) grade improved after exercise in the CAT group (pâ¯≤â¯0.01) compared to the CG, as well as improved within CAT and IAT groups. Total FSFI, and HADS-A and HADS-D scores improved after exercise in the both groups. At baseline and after the study period, there were positive correlations between scores for dis(satisfaction), HADS-A and HADS-D scores. HADS-A and HADS-D scores had a negative correlation with FSFI total in the IAT (pâ¯=â¯=0.02) group compared to the CG, as well as within CAT and IAT groups. LIMITATIONS: The participants were not matched for body mass index (normal, overweight and obese) which may interfere on body image dimensions. CONCLUSION: Aerobic exercise improves sexual function and indices related to anxiety and depression. Likewise, it interferes in cognitive-affective dimension of the body image.

OBJECTIVE: To investigate the associations among visceral adiposity index (VAI), lipid accumulation product (LAP), body fat percentage (%), and android/gynoid ratio (A/G ratio) in women with polycystic ovary syndrome (PCOS) and verify if the parameters representative of visceral obesity correlate with and exhibit the same frequency as body composition variables; anthropometric indices; and metabolic, hormonal, and inflammatory parameters. SUBJECTS AND METHODS: This was a cross-sectional study that included 94 women with PCOS. Hormonal, metabolic, and inflammatory parameters were analyzed in all women. Free androgen index (FAI) and homeostasis model assessment (HOMA-IR), as well as LAP, VAI, and anthropometric indices, were calculated. The regions of interest (ROIs) in body composition and body composition indices were evaluated using a dual X-ray absorptiometry (DXA). Overall, 32 variables were selected as markers of body fat distribution. RESULTS: Among the 32 markers evaluated, 29 correlated with LAP, whereas 25 correlated with VAI, 19 with body fat (%), and 30 with A/G ratio. Additionally, some markers correlated with the four adiposity indices evaluated: ROIs, except for total mass and leg fat (%); body composition (body mass index, waist circumference, and hip circumference) indices; fasting insulin; and C-reactive protein. CONCLUSION: LAP and VAI may be sensitive measures for screening and preventing metabolic syndrome and insulin resistance in PCOS, with LAP being more sensitive than VAI, and the A/G ratio may be more sensitive than body fat percentage.

BACKGROUND: Polycystic ovarian syndrome (PCOS) women have a high prevalence of obesity and alterations in cardiovascular autonomic control, mainly modifications in heart rate variability (HRV) autonomic modulation. However, there are few studies about other autonomic control parameters, such as blood pressure variability (BPV) and baroreflex sensitivity (BRS). In addition, there are still doubts about the obesity real contribution in altering autonomic control in these women. OBJECTIVE: To investigate BPV and BRS autonomic modulation alterations in PCOS women, as well as, to evaluate whether these alterations are due PCOS or increased body fat. METHODS: We studied 30 eutrophic volunteers [body mass index (BMI) < 25 kg/m2] without PCOS (control group) and 60 volunteers with PCOS divided into: eutrophic (BMI < 25 kg/m2, N = 30) and obese women (BMI > 30 kg/m2, N = 30). All volunteers were submitted to anthropometric evaluation, hemodynamic and cardiorespiratory parameters record at rest and during physical exercise, analysis of HRV, BPV and spontaneous BRS. The differences in p less than 5% (p < 0.05) were considered statistically significant. RESULTS: Related to eutrophics groups, there were no differences in autonomic parameters evaluated. The comparison between the PCOS groups showed that both PCOS groups did not differ in the BPV analysis. Although, the obese PCOS group presented lower values of spontaneous BRS and HRV, in low frequency and high frequency oscillations in absolute units. CONCLUSION: Our results suggest that obesity did little to alter HRV in women with PCOS, but it may influence the spontaneous BRS.

INTRODUCTION: Brazil is a large country, with a population of mixed ethnic background and broad variation in dietary and physical activity traits across its five main regions. Because data on Brazilian women with polycystic ovary syndrome (PCOS) are still scarce, a nation-wide collaborative study was designed to determine the prevalence of metabolic and reproductive abnormalities and the presence of anxiety and depression in Brazilian women with PCOS. In addition, the study aims at describing how these characteristics are distributed across PCOS phenotypes and at detecting associations with regional demographic and lifestyle aspects, genetic variants, and epigenetic markers. METHODS AND ANALYSIS: The Brazilian PCOS study is being conducted in the outpatient clinics of eight university hospitals within the public healthcare network (Unified Health System) across the country. Additional centres will be included following completion of the research ethics approval process. The sample includes women with PCOS according to Rotterdam criteria at inclusion in the study and a control group of healthy women matched by age, socioeconomic status and geographical region. Data will be collected in each centre and incorporated into a unified cloud database. Clinical, demographic, socioeconomic, psychological, metabolic, epigenetic and genotypic variables will be evaluated. The data resulting from this study will be useful to guide specific public strategies for primary and secondary prevention of metabolic and reproductive comorbidities in the PCOS population of Brazil. ETHICS AND DISSEMINATION: The study protocol was approved by each local Research Ethics Committee. Written informed consent will be obtained from each participant. During data collection, analysis and publication, care will be taken to ensure confidentiality of participant information. Study results will be published in peer-reviewed journals and disseminated at international conferences. This research protocol was registered with the Research Ethics Committee of HCPA, through Plataforma Brasil. TRIAL REGISTRATION NUMBER: CAAE 18082413.9.1001.5327.

OBJECTIVE: This study aimed to evaluate the clinical pregnancy rate of intrauterine insemination cycles in relation to patient age, cause of infertility, ovulation induction method, number of mature follicles and sperm with progressive motility. METHODS: This retrospective observational study included 237 intrauterine insemination cycles performed from 2011 to 2015 at the Assisted Reproduction Service of the Hospital das Clínicas of the Ribeirão Preto Medical School, University of São Paulo. Student's t-test was used to compare quantitative variables and the chi-square test was used to compare qualitative variables. RESULTS: Patient age was inversely and significantly correlated with pregnancy rates (p=0.001) (Pregnant women = 32.56±5.64 years, non-pregnant women = 36.64±5.03 years). Cause of infertility, ovulation induction method, number of mature follicles and sperm with progressive motility were not associated with pregnancy rates. The overall clinical pregnancy rate was 7.59%. In the subgroup of patients (n=102 cycles) considered ideal for intrauterine insemination (age ≤35 years, unexplained infertility, ovarian factor infertility or minimal endometriosis, and a partner with sperm count ≥2.5 × 106 retrieved on the day of insemination) the pregnancy rate was 12.74%. CONCLUSION: In the studied group, female patient age was the only variable significantly correlated with intrauterine insemination success rates.

ABSTRACT Objective: This study aimed to determine the differences in body fat distribution and central obesity indicators using dual-energy X-ray absorptiometry (DXA), adiposity indices, and anthropometric indices between women with and without polycystic ovary syndrome (PCOS). Materials and methods: Clinical and laboratory examination history, including transvaginal ultrasound, fasting blood samples, anthropometric measurements, and DXA scans were conducted in 179 women with PCOS (PCOS group) and 100 without PCOS (non-PCOS group). The volunteers were grouped by body mass index (BMI): normal (18-24.9 kg/m2), overweight (25-29.9 kg/m2), or obese (>30 kg/m2). The visceral adiposity index (VAI) and lipid accumulation product (LAP) were calculated, regions of interest (ROIs) were determined, and the fat mass index (FMI) was calculated using DXA. Results: VAI, LAP, ROIs, FMI, and adiposity indices by DXA were higher in women with PCOS and normal BMI. In both PCOS and non-PCOS groups, the ROIs progressively increased from normal BMI to overweight and obese, and from overweight to obese. Obese women with PCOS showed high trunk fat mass. However, obesity was not able to modify these trunk/periphery fat ratios in PCOS from overweight to higher BMI. These variables were associated with the incidence of PCOS. Conclusion: In women with PCOS and normal BMI, both DXA and the adiposity indices, VAI and LAP, are more sensitive methods to evaluate total body fat and fat accumulation in the central abdominal region. It was also observed that as BMI increased, the differences in measurements between women with and without PCOS decreased.
RESUMO
O lúpus eritematoso sistêmico é uma doença crônica, complexa e multifatorial que apresenta manifestações em vários órgãos. O seu acometimento ocorre 10 vezes mais no sexo feminino do que no masculino. É uma doença com uma clínica variada e com graus variados de gravidade, causando fadiga, manifestações cutâneas, como rash malar, fotossensibilidade, queda de cabelo e manifestações musculoesqueléticas, como artralgia, mialgia e atrite. Podem ocorrer flares (crises), que se caracterizam por aumento mensurável na atividade da doença. No climatério, no período da pré-menopausa, o lúpus eritematoso sistêmico ocorre com mais frequência, podendo ocorrer também na pós-menopausa. Algumas doenças são mais frequentes na fase do climatério, e a presença do lúpus pode influenciar na sua evolução, como a doença cardiovascular, osteoporose e tromboembolismo venoso. A terapia hormonal oral determina aumento do risco de tromboembolismo venoso no climatério, e na paciente com lúpus eritematoso sistêmico há aumento dos riscos de flares e de trombose. Em vista disso, a terapia hormonal é recomendada apenas para pacientes com lúpus eritematoso sistêmico estável ou inativo, sem história de síndrome antifosfolípides e com anticorpos antifosfolípides negativa, devendo-se dar preferência para a terapia estrogênica transdérmica, em menor dose e de uso contínuo. Na paciente com lúpus eritematoso sistêmico ativo ou com história de síndrome antifosfolípides ou com anticorpos antifosfolípides positiva, recomenda-se a terapia não hormonal, como os antidepressivos.

Systemic lupus erythematosus is a chronic, complex, multifactorial disease that manifests in several organs. Its involvement occurs 10 times more in females than in males. It is a disease with a varied clinic and varying degrees of severity, causing fatigue, skin manifestations such as malar rash, photosensitivity, hair loss and musculoskeletal manifestations such as arthralgia, myalgia and arthritis. Flare may occur, which are characterized by measurable increase in disease activity. In the climacteric, in the premenopausal period, systemic lupus erythematosus occurs more frequently, and may also occur in the postmenopausal period. Some diseases are more frequent in the Climacteric phase and the presence of lupus can influence its evolution, such as cardiovascular disease, osteoporosis and venous thromboembolism. Oral hormone therapy determines an increased risk of venous thromboembolism in the climacteric and in patients with systemic lupus erythematosus there is an increased risk of flares and thrombosis. In view of this, hormone therapy is only recommended for patients with stable or inactive systemic lupus erythematosus, without a history of antiphospholipid syndrome and with antiphospholipid antibodies, giving preference to transdermal estrogen therapy, at a lower dose and for continuous use. In patients with active systemic lupus erythematosus or with a history of antiphospholipid syndrome or positive antiphospholipid antibodies, non-hormonal therapy, such as antidepressants, is recommended.

BACKGROUND: Physiologically, a reduction in telomere length (LTL) occurs with aging, but epigenetic changes may accelerate telomere shortening and also facilitate the onset of oxidative/inflammatory stress and the development of clinical/metabolic comorbidities in life spam. Although individuals born small for gestational age (SGA) may be related to those epigenetic changes, the assessment of LTL in individuals born SGA has yielded conflicting results (only cross-sectional studies) and has not been carried out in longitudinal studies. We performed a birth cohort study to evaluate the rate of telomere erosion in women born SGA in comparison to women born appropriate for gestational age (AGA) assessed at two different time points during the third decade of life. In our research, born SGA or AGA showed no difference in LTL shortening during a period of five years in the third decade of life. Our finding may have implications for understanding the natural history of diseases in lifespan because the same women (under the influence of similar environmental factors) may be accessed in different phases of life. Thus, the analysis of the present cohort population at a more advanced age may reveal a dynamics of telomere shortening different from here and its possible relation with onset of age-related diseases.

Objective To evaluate the effects of nutritional counseling on the dietary habits and anthropometric parameters of overweight and obese adolescents with polycystic ovary syndrome (PCOS). Methods This was a prospective, longitudinal and auto-controlled study. Thirty adolescents aged 13-19 years-old, diagnosed with PCOS received nutritional counseling and were followed-up for 6 months. After the follow-up period, the results were evaluated through body weight, body mass index (BMI) and waist circumference (WC). Results Sixty-percent of the adolescents adhered to the nutritional counseling and, of these, 50% lost weight. Adolescents who lost weight changed their dietary habits by adopting hypocaloric diets and eating more meals per day, as per nutritional counseling. The waist circumference (WC) decreased significantly, although the body weight decreased non-significantly after adoption of a hypocaloric diet. Conclusion Although there was no significant weight loss, there was a considerable reduction in the WC associated with hypocaloric diets and with eating a greater number of meals per day.
Objetivo Avaliar os efeitos do aconselhamento nutricional sobre os hábitos alimentares e os parâmetros antropométricos de adolescentes com sobrepeso e obesidade e com síndrome do ovário policístico (SOP). Métodos Este foi um estudo prospectivo, longitudinal e autocontrolado. Trinta adolescentes com idades entre 13 e 19 anos e diagnosticadas com SOP receberam aconselhamento nutricional. Após 6 meses de acompanhamento, os resultados foram avaliados através do peso corporal, índice de massa corporal (IMC) e a circunferência da cintura (CC). Resultados Sessenta por cento das adolescentes aderiram ao aconselhamento nutricional e, destas, 50% perderam peso. Adolescentes que perderam peso mudaram seus hábitos alimentares adotando dietas hipocalóricas e comendo mais refeições por dia, seguindo orientação nutricional. A circunferência da cintura (CC) diminuiu significativamente, embora o peso corporal tenha diminuído de forma não significativa após a adoção de uma dieta hipocalórica. Conclusão Embora a perda de peso não tenha sido significativa, houve redução considerável da CC associada a dietas hipocalóricas e à ingestão de um maior número de refeições por dia.

Purpose Aerobic exercises may improve quality of life (QoL) in women with polycystic ovary syndrome (PCOS). However, there is no data on the effect of resistance exercise training (RET) programs on the QoL of women with PCOS. Thus, this study aimed to assess the effect of a 16-week RET program on QoL in PCOS women. Methods This 16-week case-control study enrolled 43 women with PCOS (PCOS group, PCOSG) and 51 healthy pre-menopausal controls aged 18 to 37 years (control group, CG). All women underwent a supervised RET program for 16 weeks, and were evaluated in two different occasions: week-0 (baseline), and week-16 (after RET). Quality of life was assessed using the 36-Item Short Form Health Survey (SF-36). Results Testosterone reduced significantly in both groups after RET (p < 0.01). The PCOSG had improvements in functional capacity at week-16 relative to week-0 (p = 0.02). The CG had significant improvements in vitality, social aspects, and mental health at week-16 relative to week-0 (p ≤ 0.01). There was a weak correlation between social aspects of the SF-36 domain and testosterone levels in PCOS women. Conclusion A 16-week RET program modestly improved QoL in women with PCOS.
