Does temporomandibular disorder correlate with menopausal symptoms?

OBJECTIVE: To assess the correlation between menopausal symptoms and pain caused by temporomandibular disorder (TMD) and the impact of sociodemographic factors on the association. METHODS: In this cross-sectional study, a total of 74 women with TMD symptoms were enrolled and divided into three groups according to the Stages of Reproductive Aging Workshop + 10 (STRAW + 10) criteria: G1 (n = 25, late menopausal transition), G2 (n = 30, early postmenopause), and G3 (n = 19, late postmenopause). Sociodemographic data were collected, along with data on menopausal symptoms (Blatt-Kupperman menopausal index) and TMD-induced pain (craniomandibular index). Statistical analysis was performed using a chi-squared test and linear correlation tests (Spearman and Pearson). RESULTS: Analysis of the three groups showed that TMD-induced pain was more intense in G1 than in G3 (P = 0.0426, r  = 0.2364, r2 = 0.05589), and menopausal symptoms correlated with the intensity of TMD-induced pain (P = 0.0004, r  = 0.4020). This correlation was more significant during the late menopausal transition (G1: P  = 0.0267, r  = 0.4427, r2 = 0.1960). In G2, women with fewer than 4 years of schooling had a higher total Blatt- Kupperman menopausal index score (17.0 ±â€Š85.0) and craniomandibular index (0.29 ±â€Š0.23) than women with more than 4 years of schooling (P  = 0.02 for both indices). CONCLUSIONS: Our results suggest that TMD-induced pain and menopausal symptoms are correlated, and more strongly so in the late menopausal transition. Additionally, sociodemographic factors, such as schooling, have a major influence on symptoms in early postmenopause. Performing the TMD evaluation during the climacteric period may be important.

Gynecological cancer and metabolic screening of 1001 elderly Brazilian women.

OBJECTIVE: The aim of this study was to evaluate gynecological cancer and metabolic screening of Brazilian women aged 65 years or older. METHODS: This retrospective descriptive study was conducted by including 1,001 Brazilian patients of the gynecological geriatric outpatient office of our institution to evaluate the influence of age on gynecological cancer and metabolic screening parameters at the first clinical visit. All patients were divided into three groups: a) 65 to 69 years; b) 70 to 74 years; c) ≥ 75 years. We considered clinical, laboratorial, and image data as variables of this study. The Chi-square test was used to assess the proportion of differences among the age groups, and Kruskal-Wallis was used for quantitative variables. RESULTS: The values of BMI and height in the group over 75 years was lower than that of the 65 to 69 years (p = 0.001). Regardless of the age group, high arterial blood pressure levels were found in 85.45% of participants. Also, many patients had glucose intolerance in the blood. The pelvic ultrasonography showed abnormal endometrial echo thickness (> 5 mm) in 6.14% of patients, but with no significant statistical difference between the age groups. A total of 4.04% of patients had ovaries with high volume values ( > 6.1 mL). Abnormal mammography (BI-RADS 3 or 4) was observed in 12.21%. CONCLUSIONS: our data suggest that a great reduction in BMI and stature is more frequent in the group over 75 years. Also, systemic arterial hypertension and carbohydrate disturbance are frequent morbidities in women over 65 years.

RESUMO OBJETIVO O objetivo deste trabalho foi estudar retrospectivamente alguns dados clínicos, laboratoriais e imagens de um grupo de idosas brasileiras. MÉTODOS Estudo observacional retrospectivo realizado com inclusão de 1.001 mulheres brasileiras atendidas no ambulatório de geriatria ginecológica de nossa instituição. Foram analisados: a idade dos pacientes na primeira consulta clínica e a idade na menopausa natural; alguns achados clínicos durante um exame ginecológico; resultados de análises laboratoriais. Considerou-se a relação dessas variáveis com o grupo da idade das mulheres. O teste do qui-quadrado foi utilizado para avaliar os dados e para algumas variáveis, Kruskal-Wallis ou Anova. RESULTADOS A avaliação do IMC e da estatura nas diferentes faixas etárias das mulheres mostrou que, com o aumento da idade, há diminuição do IMC e da estatura (p=0,001). Nível anormal de pressão arterial estava presente em 85,45%. De acordo com o grupo de idade, as medidas laboratoriais foram avaliadas pelo método estatístico Kruskal-Wallis, e a Anova mostrou diferença estatisticamente significante apenas no valor da creatinina, com pequeno aumento com a idade. A ultrassonografia pélvica foi alterada com espessura endometrial normal (>5 mm) em 29 (6,14%), mas sem diferença estatística significativa com os grupos de idade, e os ovários mostraram sete (4,04%) com volume anormal (>6,1). Mamografia anormal (BI-Rads 3 ou 4) foi observada em 104 pacientes (12,21%). CONCLUSÕES O estudo conclui que, com o aumento da idade, há redução do IMC e da estatura. A hipertensão é morbidade frequente. Os dados laboratoriais e a avaliação de imagens deste estudo são importantes para aumentar o conjunto de informações sobre mulheres idosas e talvez para melhorar a assistência à saúde.

Brazilian Women's Health after 65 Years of Age / Saúde de brasileiras acima dos 65 anos de idade

Abstract Purpose The aim of this study was to evaluate the health aspects of Brazilian women older than 65 years of age. Design This was a retrospective study that included 1,001 Brazilian women cared for in the gynecological geriatric outpatient office of our institution. We report a crosssectional analysis of female adults aged over 65 years, including data on demographics, clinical symptoms such as vasomotor symptoms, associated morbidities, physical examination and sexual intercourse. We used the chi-squared test to assess the data. Results The age of the patients on their first clinic visit ranged from65 to 98 years, with a mean age of 68.56 ± 4.47 years; their mean age at the time of natural menopause was 48.76 ± 5.07 years. The most frequent clinical symptoms reported during the analyzed period were hot flashes (n = 188), followed by arthropathy, asthenia, and dry vagina. The most frequent associated morbidities after 65 years of age were systemic arterial hypertension, gastrointestinal disturbance, diabetes mellitus, and depression, among others. The assessment of the bodymass index (BMI) found decreases inBMIwith increased age. At the time of the visit, 78 patients reported sexual intercourse. The majority of women reporting sexual intercourse (89.75%, n = 70) were between 65 and 69 years of age, 8.97% (n = 7) were between 70 and 74 years of age, and only 1.28% (n = 1) of those were aged older than 75 years. Conclusions Our findings suggested that vasomotor symptoms can persist after 65 years of age. There was a significant decrease in sexual intercourse with increased age. The cardiovascular disturbances in our study are health concerns in these women.

Female aging / Envelhecimento feminino

SUMMARY Female aging is a process that involves hypoestrogenism time, the individual impact on each woman, and what we can do as experts to reduce morbidity and provide quality of life. This natural process in the female life cycle has been of concern to women after menopause. Changes in different biophysical and psychosocial aspects, and their individual experiences, have repercussions on the lives of patients seeking specialized and multidisciplinary support to reduce the harmful effects of prolonged hypoestrogenism. Overweight and obesity, inadequate living habits and the presence of multi-morbidities cause damage to the quality of life and impact the functional capacity. Behavioral prescription and hormone therapy are among the treatments given to ease symptoms and reduce morbidity. A better understanding of these factors can help identify groups that require more care after menopause.

RESUMO O envelhecimento feminino é um processo em que devemos correlacionar o tempo do hipoestrogenismo com o impacto individual em cada mulher e o que poderemos fazer, enquanto especialistas, para reduzir morbidades e proporcionar qualidade de vida. Esse processo natural no ciclo de vida da mulher tem sido motivo de preocupação das mulheres na pós-menopausa. As transformações nos diferentes aspectos biofísicos, psicossociais e em suas vivências individuais trazem repercussões na vida das pacientes, que buscam apoio especializado e multiprofissional para reduzir os efeitos deletérios do hipoestrogenismo prolongado. O sobrepeso e a obesidade, inadequados hábitos de vida e a presença de multimorbidades trazem prejuízos à qualidade de vida e impactam a capacidade funcional. A prescrição comportamental e a terapia hormonal são tratamentos indicados para amenizar os sintomas e reduzir morbidades. Assim, uma melhor compreensão desses fatores pode ajudar a identificar grupos propensos a cuidados na pós-menopausa.

Metabolic disorder and obesity in 5027 Brazilian postmenopausal women.

OBJECTIVES: To evaluate the frequency of obesity in postmenopausal women and assess the potential effects of increased body mass index (BMI) on lipoprotein profile and on risk factors for arterial hypertension and diabetes. DESIGN: A cross-sectional study was conducted with 5027 postmenopausal Brazilian women. Analyses were performed of BMI and cardiovascular factors (systemic blood pressure [BP], total cholesterol, low-density lipoprotein, high-density lipoprotein [HDL-C], triglyceride, and fast glucose). The statistical analysis included the chi-square and Mann-Whitney tests. The significance level was set at 5%. RESULTS: Obesity (BMI >30) in our study characterized approximately 30% of the 5027 postmenopausal women. The comparison of patients with normal BMI and those with high BMI showed that high BMI had a significant negative effect on BP, as evidenced by the increased frequency of hypertension in overweight and obese patients (>25) (p < 0.001), that it also negatively and significantly affected triglyceride (p < 0.001) and fast glucose levels (p < 0.001), and that it was linked significantly to low levels of HDL-C. CONCLUSION: Our data showed the high frequency of obesity in our population and of the cardiovascular risks (glucose, systemic arterial hypertension, and low HDL-C) associated with high BMI.

Fitoestrogênios no tratamento da mulher no climatério / Phytoestrogens in the treatment of women in climacteric

Oral estrogen therapy may mitigate the effects of aerobic training on cardiorespiratory fitness in postmenopausal women: a double-blind, randomized clinical pilot study.

OBJECTIVE: The aim of this study was to evaluate the isolated and associated effects of oral estrogen therapy and aerobic training on cardiorespiratory fitness in postmenopausal women. METHODS: Forty-two hysterectomized healthy postmenopausal women were randomly divided (in a double-blind manner) into four groups: placebo-control (n = 9), estrogen therapy-control (n = 12), placebo-aerobic training (PLA-AT; n = 11), and estrogen therapy-aerobic training (ET-AT; n = 10). The estrogen therapy groups received estradiol valerate (1 mg/day) and the aerobic training groups trained on a cycle ergometer three times per week at moderate intensity. Before and 6 months after the interventions, all women underwent a maximal cardiopulmonary exercise test on a cycle ergometer. RESULTS: Regardless of hormone therapy, aerobic training increased oxygen uptake at anaerobic threshold (P = 0.001), oxygen uptake at respiratory compensation point (P = 0.043), and oxygen uptake at peak exercise (P = 0.020). The increases at respiratory compensation point and peak exercise were significantly greater in the groups receiving placebo than in the groups receiving estrogen (oxygen uptake at respiratory compensation point: PLA-AT +5.3 [2.8] vs ET-AT +3.0 [2.5] mL kg(-1) min(-1), P = 0.04; oxygen uptake at peak exercise: PLA-AT +5.8 [3.4] vs ET-AT +2.8 [1.4] mL kg(-1) min(-1), P = 0.02). CONCLUSIONS: Oral estrogen therapy may mitigate the cardiorespiratory fitness increase induced by aerobic training in hysterectomized healthy postmenopausal women.

Anteroposterior displacement behavior of the center of pressure, without visual reference, in postmenopausal women with and without lumbar osteoporosis.

OBJECTIVE: The aims of this study were to evaluate the anteroposterior displacement behavior of the center of pressure without any visual reference and determine its relationship with knee muscle strength and reports of falls in postmenopausal women. Among those with osteoporosis, the specific objective was to evaluate the correlation of thoracic kyphosis and vitamin D with center of pressure displacement. METHODS: This was a cross-sectional observational study without intervention. The assessments were performed on 126 postmenopausal women (aged 55-65 years) who were grouped according to their lumbar bone density into osteoporosis and control groups. Center of pressure was evaluated on a force platform (100 Hz frequency and 10 Hz filter), with the subjects standing on both feet with eyes closed for 60 seconds. Knee muscle strength was evaluated using an isokinetic dynamometer in concentric/concentric mode at a velocity of 60°/s. In the osteoporosis group, vitamin D was assayed, and the thoracic spine was radiographed. RESULTS: In the control group, there was a correlation between the center of pressure and knee strength (r = 0.37; p<0.003). Reports of falls were not associated with center of pressure displacement (p = 0.056). In the osteoporosis group, thoracic kyphosis and vitamin D levels were not correlated with the center of pressure. CONCLUSION: Anteroposterior center of pressure displacement without visual influence was not associated with falls, thoracic kyphosis or vitamin D in the osteoporosis group. Only knee muscle strength was associated with center of pressure displacement in the control group.

Polymorphisms of estrogen receptor-α gene in Brazilian women with high breast density after menopause.

UNLABELLED: The association of genetic polymorphism in the estrogen receptor alpha (ERα) gene and risk for diseases including breast cancer (BC) has been the subject of great interest. OBJECTIVE: Checking on women with high breast density after menopause, the frequency of the Pvull and Xbal polymorphisms of the ERα gene and the correlation between them and the known risk factors for breast cancer. METHOD: Observational study with 308 women between 45 and 65 years old with high breast density, without hormonal therapy, menstruation for a year or more, breast and ovarian cancer history. It was characterized in clinical history and physical examination: menarche, menopause, parity, family history of BC, smoking, alcohol intake and body mass index. RESULTS: The allelic and genotypic frequencies for ERα-Pvull and Xbal: p = 43.99%; p = 56.01%; pp = 32.14%; Pp = 47.73% and PP = 20.13%; X = 41.56%; x = 58.44%; xx = 33.44%; Xx = 50.00% and XX = 16.56%, respectively. The most frequent risk factors for BC: menarche before 12 years old (35.38%), nulliparity or first child after 28 years old (41.66%), family history of BC (19.16%) and overweight/obesity (62.01%). CONCLUSION: Allelic and genotypic distribution similar to literature. The risk factors for BC were more prevalent in women with high breast density but without significant associations with these polymorphisms.

Impact of age and body mass on the intensity of menopausal symptoms in 5968 Brazilian women.

OBJECTIVE: To assess the relationship of onset of menopause and body mass on the menopausal symptoms in post-menopausal Brazilian women. DESIGN: Observational study conducted by the selection and inclusion of 5968 Brazilian women after menopause. The following variables were analyzed in this study: time at menopause; the relationship between age at menarche and age at menopause; vasomotor symptoms compared with age at the time of menopause and the time of menopause; Kupperman menopausal index (KMI) versus total time of menopause; body mass index (BMI) compared to the time of menopause, vasomotor symptoms, and KMI total score. We used the Chi-square test, and the significance level was set at 5%. RESULTS: The age at natural menopause ranged from 41 to 62 years (mean 48.1 ± 4.07 years). A younger age at menopause was associated with a high intensity of vasomotor symptoms. These symptoms were more intense in the first 5 years of menopause and decreased with time. The KMI total also decreased with time after menopause, with the exception of arthralgia, myalgia, and insomnia, which did not tend to improve over time. In addition, the vasomotor symptoms and total KMI were more frequent with increasing BMI. CONCLUSIONS: Our results suggested that the age of menopause and BMI may influence the intensity of vasomotor symptoms.

Polimorfismo do gene do receptor estrogênico como fator de risco do câncer de mama / Gene estrogen receptor polymorphism as a risk factor in the breast cancer

Polimorfismo é uma variação genética de ocorrência habitual na população em geral, encontrado em frequência superior a 1%. Há vários polimorfismos conhecidos no gene do receptor de estrogênio alfa (REa), alguns dos quais podem modificar a função do receptor e a ação do estrogênio. Entre os polimorfismos conhecidos, Pvull, Xbal podem estar envolvidos com maior risco individual ao câncer de mama e à sobrevida em mulheres após a menopausa. O objetivo foi revisar publicações sobre a associação entre mutações em genes do REa com o risco para câncer de mama, nos últimos 20 anos. Este estudo revisou a literatura de 1990 a março de 2011 e analisou a associação entre polimorfismos do gene do REa e o risco de câncer de mama, nas principais bases de dados. Foram identificados 17 estudos caso-controle randomizados, duas revisões sistemáticas e uma metanálise que examinaram a frequência dos referidos alelos no risco de câncer de mama. As evidências mostram que fatores hormonais, em conjunto com fatores genéticos, podem aumentar a suscetibilidade individual para o câncer de mama. No entanto, é interessante observar que após estratificação para fatores já conhecidos, que levam à alta exposição ao estrógeno durante a vida, observa-se aumento de risco principalmente em mulheres após a menopausa

The polymorphism is a genetic variation that occurs in the general population, found with frequency of more than 1%. There are several known polymorphisms in the estrogen receptor alpha (ERa) gene, some of which can change the receptor function and the estrogen action. Among the known polymorphisms, Pvull and Xbal can be involved with a bigger individual risk of breast cancer and survival rate in postmenopausal women. The aim was to review the publications about the association between mutations in ERa gene with the risk for breast cancer in the last 20 years. This study reviewed the literature from 1990 to march, 2011 and analyzed the association between the polymorphism of the ERa gene and the risk of breast cancer in the main database. With identified 17 randomized case-control-studies, two systematic reviews and one meta-analysis that examined the frequency of the referred alleles in the risk of the breast cancer. The evidences showed that hormonal factors together with genetic factors could increase the individual susceptibility for the risk of breast cancer. However, it is interesting to observe that after stratification to the already known factors that lead to high exposition to the estrogen during the life, notice an increase of the risk mainly in women after the menopause
