RESUMO

Exercising prior to experimental infarction may have beneficial effects on the heart. The objective of this study was to analyze studies on animals that had exercised prior to myocardial infarction and to examine any benefits through a systematic review and meta-analysis. The databases MEDLINE, Google Scholar, and Cochrane were consulted. We analyzed articles published between January 1978 and November 2018. From a total of 858 articles, 13 manuscripts were selected in this review. When animals exercised before experimental infarction, there was a reduction in mortality, a reduction in infarct size, improvements in cardiac function, and a better molecular balance between genes and proteins that exhibit cardiac protective effects. Analyzing heart weight/body weight, we observed the following results - Mean difference 95% CI - -0.02 [-0.61,0.57]. Meta-analysis of the infarct size (% of the left ventricle) revealed a statistically significant decrease in the size of the infarction in animals that exercised before myocardial infarction, in comparison with the sedentary animals -5.05 [-7.68, -2.40]. Analysis of the ejection fraction, measured by echo (%), revealed that animals that exercised before myocardial infarction exhibited higher and statistically significant measures, compared with sedentary animals 8.77 [3.87,13.66]. We conclude that exercise performed prior to experimental myocardial infarction confers cardiac benefits to animals.

RESUMO

OBJECTIVE: To verify whether aging can modify the clinical and biochemical characteristics of women with polycystic ovary syndrome (PCOS). MATERIAL AND METHODS: This observational cross-sectional study was conducted at the reproductive endocrinology clinics of Julio Muller University Hospital and Tropical Institute of Reproductive Medicine in Cuiabá, MT, Brazil, between 2003 and 2017. Both, 796 PCOS and 444 non-PCOS normal cycling women underwent the same examination. PCOS was diagnosed using the Rotterdam criteria as recommended for adolescent and adult subjects. Anthropometric, metabolic, and endocrinological modifications with aging were initially examined in the two groups: control and PCOS. Further analyses were performed after a 5-year-age stratification of data throughout the reproductive period. All participants signed a consent form approved by the local Ethical Committee. RESULTS: Biomarkers of adiposity were more remarkable in African descendant PCOS women. Body weight, waist/hip ratio, fat mass and body mass index were higher in PCOS women and tended to increase at all 5 age-strata, between ≤19 and 35-years of age. Serum androgen levels decreased with aging, markedly in PCOS subjects (p<0.01 for all age-strata comparisons) but remained elevated when compared with the levels found in controls. Carbohydrate markers, triglycerides and total cholesterol tended to increase over time in PCOS (p<0.01 for all age-strata comparisons). Total cholesterol also tended to increase with age in non-PCOS women (p=0.041). CONCLUSION: The present study has shown that the advancing age influences many features of PCOS women. Biochemical hyperandrogenism, the core criterion recommended in the current systems to define the syndrome, showed statistically significant tendencies to decrease with aging progression but did not normalize. The use of age-adjusted features for the diagnosis of PCOS are recommended.

RESUMO

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.

RESUMO

Melatonin is known for its effects on both the sleep and reproductive system of mammals. The latter has melatonin receptors type 1 and 2, which act to regulate, among other things, cyclic AMP. Notwithstanding all the literature data, there is still no sound knowledge or a clear understanding of the hormone's action on the physiology of ovarian follicular cells. OBJECTIVE To review and evaluate studies about melatonin action on the ovarian granulosa/theca interna cells from the literature. METHODS The systematic review was carried out according to the PRISMA recommendations. The MEDLINE and Cochrane primary databases were consulted with the use of specific terms. There was no limitation on language or publication year. RESULTS Seven papers about melatonin action on granulosa cells were selected. The following can be attributed to the hormone's effects: a) progesterone increase in culture medium; b) increased estrogen production; c) antagonistic action on estrogen; d) improvement in cell quality resulting in improved embryo and higher pregnancy rates; e) improved cell proliferation via MAPK; f) reduction of free radicals. Nevertheless, there are contrarian papers reporting a reduction in progesterone production. Melatonin interferes in sex steroid production, boosting progesterone output. Such action may help improve oocyte quality.

RESUMO A melatonina é conhecida por seus efeitos no sono e no sistema reprodutivo dos mamíferos. Este último tem receptores de melatonina tipos 1 e 2, que atuam para regular, entre outras coisas, o AMP cíclico. Apesar de todos os dados da literatura, ainda não há um conhecimento sólido ou uma compreensão clara da ação do hormônio na fisiologia das células foliculares ovarianas. OBJETIVO Revisar e avaliar estudos da ação da melatonina na literatura sobre as células internas da granulosa/teca ovariana. MÉTODOS A revisão sistemática foi realizada de acordo com as recomendações do Prisma. As bases de dados primárias Medline e Cochrane foram consultadas com o uso de termos específicos. Não houve bar na língua ou ano de publicação. RESULTADOS Sete artigos sobre a ação da melatonina nas células da granulosa foram selecionados. O que se segue pode ser atribuído aos efeitos do hormônio: a) aumento de progesterona no meio de cultura; b) aumento da produção de estrogênio; c) ação antagônica no estrogênio; d) melhoria na qualidade celular, resultando em melhor embrião e maiores taxas de gravidez; e) melhor proliferação celular via MAPK; f) redução de radicais livres. No entanto, existem artigos controversos relatando redução na produção de progesterona. CONCLUSÃO A melatonina interfere na produção de esteroides sexuais, aumentando a produção de progesterona. Tal ação pode ajudar a melhorar a qualidade do oócito.

RESUMO

BACKGROUND: To determine whether age is a barrier against acceptability of cervicovaginal self-sampling in screening for cervical cancer at two gynecology outpatient clinics. METHODS: This is a cross-sectional study involving 116 women over 21 years of age with an abnormal Pap smear. Clinical and laboratorial data were recorded in electronic files. Women received detailed self-collection instructions. After the self-sampling procedure (Evalyn Brush®), women were instructed to answer a questionnaire about vaginal self-sampling acceptability that consisted of seven multiple-choice items. The participants were divided into three age brackets: 21 to 29 years, 30 to 49 years, and 50 years and over. Chi-square, Fischer exact, Kolmogorov-Smirnov and Kruskal-Wallis tests were used. RESULTS: The analysis of the participants' perception of the procedure stratified according to age groups showed a decline in the fear of hurting oneself during the procedure as age increased. Most participants reported that it was very easy to understand how to use the self-sampling brush and that it was easy to use it. Most of them were neither embarrassed nor afraid of getting hurt during the procedure. The majority preferred self-sampling to collection by a healthcare professional. The main reason was practicality: the possibility of choosing the place and time for sampling. CONCLUSIONS: The participating women found self-collection simple to understand and easy to accept regardless of age. The younger women indicated more fear and discomfort in self-sampling, which points to the need for attraction strategies that are more appealing to the younger generations.

RESUMO

Breast Cancer is common in women, but its etiology is not yet fully understood. Several factors may contribute to its genesis, such as genetics, lifestyle, and the environment. Melatonin may be involved in the process of breast cancer. Therefore, the aim of this study is to evaluate the influence of the levels of melatonin on breast cancer through a systematic review and meta-analysis. We performed a systematic review according to PRISMA recommendations. The primary databases MEDLINE, Embase, and Cochrane were consulted. There was no restriction on the year of publication and language. Data of systematic reviews from April 2017 to September to 2017 were analyzed. The meta-analysis was conducted using RevMan 5.3 software provided by the Cochrane Collaboration. From a total of 570 articles, 9 manuscripts were included in this review. They analy onzed women with breast cancer and control patients, of which 10% and 90% were in the reproductive period and after menopause, respectively. The lowest level of melatonin was found in approximately 55% of studies with breast cancer in post-menopause. The metanalyses of the studies demonstrated low levels of melatonin in breast cancer patients (n=963) compared with control patients (n= 1332), with a mean difference between the studies of -3.54 (CI -6.01, -1.06). Another difference found was in the comparison between smoking patients, with an average difference between 1.80 [0.97-2.63]. Our data suggest that low levels of melatonin might be a risk factor for breast cancer.

RESUMO O câncer de mama é comum em mulheres, mas sua etiologia ainda não é totalmente compreendida. Vários fatores podem contribuir para sua gênese, genética, estilo de vida e meio ambiente. A melatonina pode estar envolvida no processo de câncer de mama. Portanto, o objetivo deste estudo é avaliar a influência dos níveis de melatonina no câncer de mama por meio de uma revisão sistemática e meta-análise. Realizamos uma revisão sistemática de acordo com as recomendações do Prisma. Os principais bancos de dados, Medline, Embase e Cochrane, foram consultados. Não houve restrição quanto ao ano de publicação e idioma. Os dados de revisão sistemática obtidos de abril de 2017 a setembro a 2017 foram analisados. A meta-análise foi conduzida pelo programa RevMan 5.3 fornecido pela Cochrane Collaboration. De um total de 570 artigos, nove foram incluídos nesta revisão. As análises foram conduzidas em mulheres com câncer de mama e pacientes controle, dos quais 10% e 90% estavam no período reprodutivo e após a menopausa, respectivamente. O nível mais baixo de melatonina foi encontrado em aproximadamente 55% dos estudos com câncer de mama na pós-menopausa. As meta-análises de estudos demonstraram os baixos níveis de melatonina em doentes com câncer da mama (n=963), em comparação com os pacientes de controle (n=1.332), sendo a diferença de médias entre os estudos da −3,54 (CI −6,01, −1,06). Outra diferença é demonstrada nas comparações entre pacientes fumantes, sendo a diferença da média entre 1,80 [0,97-2,63]. Nossos dados sugerem que baixos níveis de melatonina podem ser um fator de risco para câncer de mama.

RESUMO

Abstract Background ABO blood group incompatibility between donor and recipient is associated with a number of immunohematological complications, but is not considered a major contraindication to allogeneic hematopoietic stem cell transplantation. However, available evidence from the literature seems to be conflicting as to the impact of incompatibility on overall survival, event-free survival, transplant-related mortality, graft-versus-host disease, and time to neutrophil and platelet engraftment. Methods This single-center, prospective, cohort study included patients with hematological malignancies who underwent a first allogeneic hematopoietic stem cell transplantation between 2008 and 2014. Patients receiving umbilical cord blood as the stem cell source were excluded from this analysis. The impact of ABO incompatibility was evaluated in respect to overall survival, event-free survival, transplant-related mortality, acute graft-versus-host disease and engraftment. Results A total of 130 patients were included of whom 78 (60%) were males. The median age at transplant was 36 (range: 2-65) years, 44 (33%) presented ABO incompatibility, 75 (58%) had acute leukemia, 111 (85%) had a related donor, 100 (77%) received peripheral blood hematopoietic stem cells as graft source and 99 (76%) underwent a myeloablative conditioning regimen. There was no statistically significant association between ABO incompatibility and overall survival, event-free survival, transplant-related mortality, grade II-IV acute graft-versus-host disease, neutrophil or platelet engraftment in multivariate analysis. Conclusion These results show that ABO incompatibility does not seem to influence these parameters in patients undergoing allogeneic hematopoietic stem cell transplantation.

RESUMO

Abstract Considering that myths and misconceptions regarding natural procreation spread rapidly in the era of easy access to information and to social networks, adequate counseling about natural fertility and spontaneous conception should be encouraged in any kind of health assistance. Despite the fact that there is no strong-powered evidence about any of the aspects related to natural fertility, literature on how to increase the chances of a spontaneous pregnancy is available. In the present article, the Brazilian Federation of Gynecology and Obstetrics Associations (FEBRASGO, in the Portuguese acronym) Committee on Endocrine Gynecology provides suggestions to optimize counseling for non-infertile people attempting spontaneous conception.


Resumo Uma vez que mitos e equívocos sobre a procriação natural se espalham rapidamente na era do fácil acesso à informação e às redes sociais, o aconselhamento adequado sobre a fertilidade natural e a concepção espontânea deve ser encorajado em qualquer tipo de assistência à saúde. Apesar do fato de não haver evidências fortes sobre qualquer dos aspectos relacionados à fertilidade natural, existe literatura sobre como aumentar as chances de uma gravidez espontânea. No presente artigo, a Comissão Nacional de Ginecologia Endócrina da Federação Brasileira das Associações de Ginecologia e Obstetrícia (FEBRASGO) oferece sugestões para otimizar o aconselhamento a pessoas que tentam a concepção espontânea, na ausência do diagnóstico de infertilidade.

RESUMO

The current reference standard to check the position of a tubal sterilization microinsert device after its insertion is hysterosalpingography. The objective of this study was to evaluate the accuracy of 2-dimensional (2D) and 3-dimensional (3D) ultrasonography (US) in the positioning of the tubal sterilization microinsert for definitive contraception. We searched MEDLINE, Embase, Cochrane, and Scopus databases through October 2017. Selection criteria included studies that analyzed the accuracy of 2D or 3D US, or both, with respect to the positioning of the microinsert. Data were displayed as forest plots and a summary receiver operating characteristic curves. Values for sensitivity, specificity, and positive and negative likelihood ratios (LRs) were calculated. The pooled analysis produced sensitivity and specificity values for 2D US in the positioning of the microinsert of 0.88 (95% confidence interval [CI], 0.47-1.0) and 0.92 (95% CI, 0.88-0.95), respectively, with positive and negative LRs of 8.68 (95% CI, 1.63-46.1) and 0.35 (95% CI, 0.11-1.11), respectively. Three studies analyzed the performance of 3D US, showing sensitivity, specificity, and positive and negative LRs of 0.75 (95% CI, 0.35-0.97), 0.82 (95% CI, 0.77-0.87), 3.65 (95% CI, 2.31-5.75), and 0.46 (95% CI, 0.2-1.09). In conclusion, 2D and 3D US are methods that show good accuracy in tubal sterilization microinsert positioning.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the histomorphometry of the skin of women during the reproductive period according to the Fitzpatrick classification. METHODS: Thirty women aged 30 to 45 years were included in this study. We studied the surgical sites of extracted nevi. The material was processed for routine histology and then stained with haematoxylin and eosin as well as Picrosirius red. Four-micrometre histological sections were analysed according the Fitzpatrick criteria (skin pigmentation). The skin thickness and collagen concentration were determined for the reticular dermal skin. The data were statistically analysed with ANOVA. RESULTS: Fitzpatrick skin types I and II were thicker than the other skin types. CONCLUSIONS: Our data suggest that white skin may be less thick than dark skin.

RESUMO

BACKGROUND: Some researchers have suggested that HIV infections can increase the cytokines, which might interfere with the bone metabolism and increase the risk of bone mass loss. However, this issue has yet to be consolidated in postmenopausal women. OBJECTIVE: To analyze studies that evaluated the loss of bone mass through DEXA in women living with HIV. MATERIALS AND METHODS: A systematic review was conducted following the PRISMA guideline. The MEDLINE, EMBASE and Cochrane databases were consulted from January 1987 to March 2017. Studies assessing bone mineral density (BMD) in postmenopausal women living with HIV were included. The secondary outcome was to evaluate the impact of antiretroviral on BMD. RESULTS: Sixty percent of the manuscripts suggested that women living with HIV had more bone loss than women in the control group, mainly in the lumbar spine. Forty percent did not observe any difference between groups. One study reported the influence of antiretroviral drugs on bone mass but did not find any difference between groups. CONCLUSION: Our data suggest that HIV infections may have a negative influence on bone mass loss in women. Further studies on the mechanism of this HIV consequence are necessary to clarify the connection as well as the impact of the antiretroviral action on BMD in postmenopausal women.
