The study described psychophysiological responses (perceived exertion, affective response) of women with polycystic ovary syndrome (PcOS) throughout 10 sessions of high-intensity interval training (HIIT). Methods. Overall, 12 physically inactive women with PcOS (age: 26.2 ± 4.1 years; body mass index: 28.5 ± 6.3 kg/m 2) performed 10 running HIIT sessions of 50 min [10 × 1-min intervals, 90% of maximal heat rate (HRmax); 3-min active recovery periods, 70% HRmax], including 5-min warm-up and cool-down, with 48-hour intervals. HRmax, rating of perceived exertion (RPE, Borg cR10 scale), and affective responses (Feeling Scale) were assessed in the last 10 s of each interval and recovery period. Each session responses were grouped into session parts (beginning, 1-3; middle, 4-7; end, 8-10) for intervals and recovery periods separately. The generalized estimating equation model served to compare %HRmax, RPE, and affective valence between session parts. Results. The intensities of intervals (p < 0.001) and recovery (p < 0.001) increased from session beginning to end, as did RPE of intervals (p < 0.001) and recovery (p < 0.001). Interval affective responses were lower at end compared with beginning (p < 0.040). HIIT intensity (%HRmax) presented a small coefficient of variation (cV, ca. 3%); RPE exhibited medium cV (ca. 20%) between 10 HIIT sessions. Conclusions. Psychophysiological responses of physically inactive PcOS women to running HIIT demonstrate positive affective valence at the beginning of HIIT sessions. As the session progresses, affective valence decreases to neutral and RPE increases.

MÉTODOS: Foram analisadas, retrospectivamente, 189 pacientes com síndrome dos ovários policísticos. O diagnóstico de resistência à insulina foi obtido utilizando-se insulinemia, HOMA-IR, QUICKI, índice de sensibilidade à insulina e relação glicemia/insulina. Foram utilizados o índice de massa corpórea e o lipid accumulation product. Para análise dos resultados, aplicou-se a estatística descritiva, a ANOVA, o pós-teste de Tukey e a correlação de Pearson. RESULTADOS: As pacientes apresentaram média de idade de 24,9±5,2 e de índice de massa corpórea de 31,8±7,6. O percentual de pacientes obesas foi de 57,14%. Dentre os métodos de investigação de resistência à insulina, o índice de sensibilidade à insulina foi a técnica que mais detectou (56,4%) a presença de resistência à insulina nas mulheres com síndrome dos ovários policísticos. Em 87% das pacientes obesas, detectou-se a resistência à insulina. A relação glicemia/insulinemia de jejum e o índice de sensibilidade à insulina apresentaram correlação forte com o lipid accumulation product. CONCLUSÃO: A prevalência de resistência à insulina variou de acordo com o método utilizado e foi maior quanto maior o índice de massa corpórea. O lipid accumulation product também está relacionado à resistência à insulina.

Menstrual Cycle Irregularity as a Marker of Cardiovascular Risk Factors at Postmenopausal Years. ... more Menstrual Cycle Irregularity as a Marker of Cardiovascular Risk Factors at Postmenopausal Years. To evaluate the association between cardiovascular risk factors (CVRF) during postmenopausal years and previous menstrual irregularity during reproductive years, we performed a case-control study in 414 postmenopausal women (mean age 60.4 ± 5.5 years; BMI 25.3 ± 4.7 kg/m 2). The variables assessed were: menstrual cycle characteristics at age 20-35y (independent) and records of arterial hypertension, dyslipidemia, diabetes mellitus, and coronary heart disease (dependent). Statistical analysis used the chi-square test and logistic regression, adjusting for potential confounders for cardiovascular risk, with significance set at 5%. Women reporting previous menstrual irregularity were associated with increased risk for some CVRF [adjusted odds ratio (OR) 2.14; CI-95%= 1.02-4.48], when compared with those reporting regular menstrual cycles. Stratified analysis demonstrated significant associations of previous menstrual irregularity with: arterial hypertension [OR= 2.74; CI-95%= 1.39-5.41), hypercholesterolemia (OR= 2.32; CI-95%= 1.17-4.59), hypertriglyceridemia (OR= 2.09; CI-95%=1.10-4.33), and coronary angioplasty artigo original

No soro de indivíduos normais, a forma monomérica é a predominante (85-95%), enquanto a "big-big" PRL constitui a forma menos frequente (<1%) 3. A hiperprolactinemia é uma das alterações endócrinas mais comuns do eixo hipotálamohipofisário, acometendo 0,4% da população adulta e 9-17% das mulheres com distúrbios reprodutivos. Sua etiologia é variada e, excluindo-se as causas fisiológicas, o uso de algumas medicações e o hipotireoidismo, os tumores hipofisários secretores ou não de PRL representam a principal causa de hiperprolactinemia. As manifestações clínicas da hiperprolactinemia compreendem uma série de sintomas como os distúrbios menstruais, galactorreia, infertilidade, hirsutismo e alterações neurooftalmológicas, estas últimas quando a causa é um tumor de maiores proporções. A longo prazo, a hiperprolactinemia pode levar à osteoporose como consequência do hipoestrogenismo que se estabelece nessas pacientes. A associação desses sintomas e sinais com elevação dos níveis de PRL plasmática torna obrigatória, portanto, a investigação da etiologia com foco especial na detecção de um tumor hipofisário, principalmente os secretores de PRL, chamados prolactinomas, o que é feito sistematicamente através de exames de imagem como a Tomografia Computadorizada (TC) e a Ressonância Nuclear Magnética (RNM) 4 .

Materials and Methods: Transperineal ultrasound examination was used to evaluate the thickness of the bilateral pelvic floor muscles Results: The mean age was 25.1 ± 2.1 and 24.2 ± 1.9 years in PCOS and control groups, respectively (p > 0.05). Body mass index averaged 22.5 ± 0.9 in the control group and 27.8 ± 2.6 in the PCOS group (p = 0.03). There was no difference between the thickness of the pelvic floor muscles (PCOS group: right 1.12 ± 0.5, left 1.0 ± 0.6 and control group: right 0.89 ± 0.6 and left 0.94 ± 0.4. Conclusions: There was no differences in pelvic floor muscle thickness identified by ultrasound. However, the PCOS group exhibited a tendency to greater thickness. This may be due to the state of hyperandrogenism or abdominal overload.

Materials and Methods: A cross-sectional observation study of 102 women, divided into three groups: control (CG), third trimester (G3), and lactation group (LG). The study variables were skin, subcutaneous adipose tissue, fibroglandular tissue, retromammary adipose tissue thickness, duct diameter, and pulsatility (PI) and resistance indices (RI) of the internal mammary arteries. Statistical analysis calculated the means and standard deviations, using two models Multivariate Analysis of Variance (MANOVA) models to assess the effect of groups on the mean values found and adjusted ANOVA models for individual means. The Tukey-Kramer multiple comparisons test was used to analyze intergroup. Results: There was no intergroup age difference (mean = 27 ± 4.76 years). A significant difference was observed between the G3/LG and the CG in terms of skin (p = 0.001), fibroglandular tissue thickness, duct diameter, and laser Doppler flow measurements of the IMA (all three with p < 0.001) and subcutaneous adipose tissue (p = 0.045). Conclusion: This study showed alterations in skin, subcutaneous adipose tissue, fibroglandular tissue, and duct diameter measurements, with a difference between pregnant/lactating women and the non-pregnant controls.

Materials and methods Cross-sectional study involving 196 students of public schools (11-19 years old). The following risk factors were considered in the analysis: excess weight, central obesity, dyslipidemia, high blood pressure, and high fasting glucose. The ratio between observed and expected prevalence and its confidence interval were used to identify clustering of risk factors that exceeded expected prevalence in the population. Results The most prevalent risk factors were dyslipidemia (70.9%), and central obesity (39.8%), followed by excess weight (29.6%), and high blood pressure (12.8%). A total of 42.9% of adolescents had two or more risk factors, and 24% had three or more. Excess weight, central obesity, and dyslipidemia were common risk factors in the clustering patterns that showed higher-than-expected prevalence. Conclusions Clustering of risk ...

[Subjects and Methods] This cross-sectional study involved 30 women with ovulatory menstrual cycles. Total testosterone and estradiol levels were measured and the muscle tone and maximum voluntary contraction of the pelvic floor muscles were evaluated using surface electromyography. [Results] Muscle tone was significantly lower during the follicular (21.1±3.3 μV) and ovulatory (27.1±5.9 μV) phases than the luteal phase (30.4±4.1 μV). The maximum voluntary contraction was not different across phases. The estradiol level on the 7th day of the menstrual cycle showed a strong positive correlation with muscle tone and maximum voluntary contraction, and the testosterone level was positively correlated with muscle tone on the 21st day. [Conclusion] Women have better muscle tone during the luteal phase. The muscle tone and maximum voluntary contraction were strongly correlated with the estradiol level on the 7th day, and the muscle tone was correlated with the testosterone level on the 21st day of the menstrual cycle. These findings suggest that hormonal fluctuations during the menstrual cycle alter pelvic floor muscle activity.

PCOS has a significant negative impact on the health-related quality of life (HRQoL) and psychological function of women, of which there are reports of high levels of depression in women with PCOS compared to those without PCOS. However, the evidence surrounding the effects of exercise and/or dietary intervention participation on the HRQoL of women with PCOS is limited. Therefore, our objective is to examine the effects of lifestyle interventions (definition include exercise-only, diet-only, exercise + diet and behavioral or combined) on health-related quality of life or general quality of life in women with PCOS. Methods: We will conduct an update of systematic review and we will follow the recommendations and guidelines of the Cochrane handbook for systematic reviews and Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol (PRISMA-P). We will search the studies in the following databases: MEDLINE. PubMed, PsychINFO, Embase, SportDiscus, Web of Science, Cochrane Database (via Cochrane library), Cochrane Controlled Register of Trials (CENTRAL), and Google Scholar (advance). Manual search of the reference list of identified works, without language and year restrictions. The process of study selection and data extraction will be performed independently by 2 reviewers, with a third reviewer being responsible for the final decision in case of disagreement between the first two. We will use Egger funnel chart to evaluate possible publication biases, in addition, when possible we will perform a subgroup/meta-regression analysis. The strength of the evidence will be assessed according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE).
