Are women with endometriosis more likely to experience reduced physical performance compared to women without the condition?

Background: Endometriosis is a condition of the female reproductive system associated with pelvic pain. Chronic pain can affect physical performance by limiting the functional activities, thus, it is hypothesized that women with endometriosis may also present decreased functional capacity, decreased strength, and mobility. The objective of this study is to compare physical performance in women with and without endometriosis. Methods: This is a cross-sectional study composed of 115 women equally divided into two groups: the endometriosis group (EG), composed of women with a confirmed diagnosis of the disease by magnetic resonance imaging, and the comparator group (CG), consisting of women without suspicion of the disease. Physical performance (dependent variable) was assessed using hand dynamometry, the 6-min walk test (6MWT), gait speed, and the chair stands test. CG participants performed the tests during the luteal phase of the menstrual cycle. Descriptive statistics, unpaired t-tests, and chi-square tests were used to describe and compare the groups. Multiple linear regression tested the associations adjusted for covariates (age, income, education, age at menarche, and body mass index). Results: The EG had worse gait speed (mean difference: -0.11; 95% CI: [-0.18 to -0.04]), weaker grip strength (mean difference: -3.32; 95% CI: [-5.30 to -1.33]), shorter distance covered in the 6MWT (mean difference: -83.46; 95% CI: [-121.38 to -45.53]), and a lower number of repetitions in the chair stands test (mean difference: -8.44; 95% CI: [-10.64 to -6.25]) than the CG, even after adjusting for covariates. Conclusion: Grip strength, lower limb strength, mobility, and functional capacity were worse in women diagnosed with endometriosis. Women with endometriosis should be encouraged to engage in physical exercise, adopt healthy lifestyle habits, and participate in rehabilitation activities to control pain, with the aim of reducing functional impairments.

Neuroprotective effects of açaí (Euterpe oleracea Mart.) against diabetic retinopathy.

Introduction: Diabetes mellitus describes a metabolic disorder of multiple etiologies, characterized by chronic hyperglycemia, which induces a series of molecular events capable of leading to microvascular damage, affecting the blood vessels of the retina, causing diabetic retinopathy. Studies indicate that oxidative stress plays a central role in complications involving diabetes. Açaí (Euterpe oleracea) has attracted much attention given its antioxidant capacity and potential associated health benefits in preventing oxidative stress, one of the causes of diabetic retinopathy. The objective of this work was to evaluate the possible protective effect of açaí (E. oleracea) on the retinal function of mice with induced diabetes, based on full field electroretinogram (ffERG). Methods: We opted for mouse models with induced diabetes by administration of a 2% alloxan aqueous solution and treatment with feed enriched with açaí pulp. The animals were divided into 4 groups: CTR (received commercial ration), DM (received commercial ration), DM + açaí (E. oleracea-enriched ration) and CTR + açaí (E. oleracea-enriched ration). The ffERG was recorded three times, 30, 45 and 60 days after diabetes induction, under scotopic and photopic conditions to access rod, mixed and cone responses, in addition to monitoring the weight and blood glucose of the animals during the study period. Statistical analysis was performed using the two-way ANOVA test with Tukey's post-test. Results: Our work obtained satisfactory results with the ffERG responses in diabetic animals treated with açaí, where it was observed that there was no significant decrease in the b wave ffERG amplitude of this group over time when compared to the results of the Diabetic group not treated with açaí, which showed a significant reduction of this ffERG component. Discussion: The results of the present study show, for the first time, that treatment with an açaí-enriched diet is effective against the decrease in the amplitude of visual electrophysiological responses in animals with induced diabetes, which opens a new horizon for the prevention of retinal damage in diabetic individuals from treatment with açaí base. However, it is worth mentioning that our findings consist of a preliminary study and further researches and clinical trials are needed to examine açaí potential as an alternative therapy for diabetic retinopathy.

Spatio-temporal analysis of leptospirosis in Eastern Amazon, State of Pará, Brazil.

INTRODUCTION: Brazil has registered more than 62,000 confirmed cases of leptospirosis between 2001 and 2017, with more than 2,000 cases confirmed in the State of Pará. Despite a large number of cases, no study has been conducted to trace the spatio-temporal profile of the disease. METHODOLOGY: Confirmed cases of leptospirosis from 2001 to 2017 from the state of Pará were the basis for this space-time study. The database of the Department of Informatics of the Ministry of Health was used to access data on leptospirosis. The spatio-temporal analysis was performed in the SaTScan software for the detection of clusters, and maps were generated in the QGIS software. RESULTS: The municipalities of Belém and Santarém were among the ones with the highest incidence rates of leptospirosis for the whole study period. Increased number of cases in Soure, Inhangapi, São João da Ponta and Magalhães Barata, Ponta de Pedras, Breves, Bragança, Castanhal, and São Domingos do Capim were identified in different time periods. Santarém and Belém are the main foci of leptospirosis because they are the most urbanized and densely populated municipalities in the State. The cases found in smaller municipalities may be associated with periods of more frequent rainfall and circulation of Leptospira sp. in marsupials and cattle, in the northeastern part of the State. CONCLUSION: Further studies are needed to help identify the risk factors that contribute to the occurrence of leptospirosis in the State of Pará, particularly in areas with lower population density.

RESUMO: Introdução: O Brasil registrou mais de 62 mil casos de leptospirose confirmados entre 2001 e 2017, com mais de 2.000 casos confirmados no estado do Pará. Apesar da grande quantidade de casos, nenhum estudo até este momento traçou o perfil espaço-temporal da doença. Metodologia: Este é um estudo espaço-temporal com base nos casos confirmados de leptospirose entre 2001 a 2017 no estado do Pará. O banco de dados do Departamento de Informática do Ministério da Saúde foi utilizado para acessar os dados de leptospirose. A análise espaço-temporal foi realizada no software SaTScan para detecção de clusters e os mapas foram gerados no software QGIS. Resultados: O município de Belém e Santarém se mantiveram entre as maiores taxas de incidência de leptospirose durante todo o período estudado. O aumento no número de casos em Soure, Inhangapi, São João da Ponta e Magalhães Barata, Ponta de Pedras, Breves, Bragança, Castanhal e São Domingos do Capim foram identificados em diferentes períodos. Santarém e Belém são os principais focos de leptospirose por serem os municípios mais urbanizados e com maior densidade populacional do estado. Os casos observados em municípios menores podem estar associados a períodos de maior pluviosidade e circulação de Leptospira sp. em marsupiais e em gado no nordeste do estado. Conclusão: Com o exposto, torna-se necessário mais estudos visando o conhecimento dos fatores que contribuem com a ocorrência da leptospirose no estado do Pará, particularmente em áreas com menor adensamento populacional.
