Physical activity, health-related quality of life and depression during pregnancy

This study examines physical activity patterns among women, from pre-pregnancy to the second trimester of pregnancy, and the relationship between physical activity status based on physical activity guidelines and health-related quality of life (HRQoL) and depression over pregnancy. 56 healthy pregnant women self reported physical activity, HRQoL and depression at 10-15 and 19-24 weeks of pregnancy and physical activity before pregnancy. Whereas vigorous leisure physical activity decreased after conception, moderate leisure physical activity and work related physical activity remained stable over time. The prevalence of recommended physical activity was 39.3% and 12.5% in the 1st and 2nd trimesters of pregnancy respectively, and 14.3% pre-pregnancy. From the 1st to the 2nd pregnancy trimester, most physical HRQoL dimensions scores decreased and only mental component increased, independently of physical activity status. No changes in mean depression scores were observed. These data suggest that physical activity patterns change with pregnancy and that physical and mental components are differentially affected by pregnancy course, independently of physical activity status.

Validation of the Portuguese Version of EHP-30 (The Endometriosis Health Profile-30)

Introduction: Endometriosis Health Profile Questionnaire-30 is currently the most used questionnaire for quality of life measurement in women with endometriosis. The aim of this study is to evaluate the psychometric properties and to validate the Portuguese Endometriosis Health Profile Questionnaire-30 version. MATERIAL AND METHODS A sequential sample of 152 patients with endometriosis, followed in a Portugal reference center, were asked to complete a questionnaire on social and demographic features, the Portuguese version of the Endometriosis Health Profile Questionnaire-30 and of the Short Form Health Survey 36 Item â version 2. Appropriate statistical analysis was performed using descriptive statistics, factor analysis, internal consistency, item-total correlation and convergent validity. RESULTS Factorial analysis confirmed the validity of the five-dimension structure of the Endometriosis Health Profile Questionnaire-30 core questionnaire, which explained 83.2% of the total variance. All item-total correlations presented acceptable results and high internal consistency, with Cronbach's alpha ranging between 0.876 and 0.981 for the core questionnaire and between 0.863 and 0.951 for the modular questionnaire. Significant negative associations between similar scales of Endometriosis Health Profile Questionnaire-30 and Short Form Health Survey 36 Item â version 2 were demonstrated. Data completeness achieved was high for all dimensions. The emotional well-being scale in the core questionnaire and the infertility scale in the modular section had the highest median scores, and therefore the most negative impact on the quality of life of participating women. DISCUSSION The test-retest reliability and responsiveness of the questionnaire should be evaluated in future studies. CONCLUSION The present study demonstrates that the Portuguese version of the Endometriosis Health Profile Questionnaire-30 is a valid, reliable and acceptable tool for evaluating the health-related quality of life of Portuguese women with endometriosis.

A critical evaluation of methods for the reconstruction of tissue-specific models

Under the framework of constraint based modeling, genome-scale metabolic models (GSMMs) have been used for several tasks, such as metabolic engineering and phenotype prediction. More recently, their application in health related research has spanned drug discovery, biomarker identification and host-pathogen interactions, targeting diseases such as cancer, Alzheimer, obesity or diabetes. In the last years, the development of novel techniques for genome sequencing and other high-throughput methods, together with advances in Bioinformatics, allowed the reconstruction of GSMMs for human cells. Considering the diversity of cell types and tissues present in the human body, it is imperative to develop tissue-specific metabolic models. Methods to automatically generate these models, based on generic human metabolic models and a plethora of omics data, have been proposed. However, their results have not yet been adequately and critically evaluated and compared. This work presents a survey of the most important tissue or cell type specific metabolic model reconstruction methods, which use literature, transcriptomics, proteomics and metabolomics data, together with a global template model. As a case study, we analyzed the consistency between several omics data sources and reconstructed distinct metabolic models of hepatocytes using different methods and data sources as inputs. The results show that omics data sources have a poor overlapping and, in some cases, are even contradictory. Additionally, the hepatocyte metabolic models generated are in many cases not able to perform metabolic functions known to be present in the liver tissue. We conclude that reliable methods for a priori omics data integration are required to support the reconstruction of complex models of human cells.

Actividade física e qualidade de vida na gravidez

Pouco se conhece acerca da actividade física e qualidade de vida da mulher na gravidez. Este estudo teve como objectivos 1) comparar os padrões de actividade física antes e durante a gravidez, 2) avaliar a percepção da qualidade de vida relacionada com a saúde durante os primeiros seis meses de gestação, e 3) comparar a percepção da qualidade de vida nas mulheres activas e insuficientemente activas considerando as recomendações de saúde pública. Método: Estudo longitudinal com 59 grávidas seleccionadas em consultórios médicos privados. Às 10-15 semanas foi recolhida informação sociodemográfica e médica, bem como informação sobre a actividade física três meses antes da concepção. Medidas de auto-relato foram administradas entre as 10-15 semanas e as 19-24 semanas de gestação para avaliar o tempo de actividade física (QAFG) (no trabalho, lazer, deslocações) e a qualidade de vida (SF-36). Resultados: A prevalência de actividade física recomendada é menor durante do que antes da gravidez (16.7% e 17.5% nos 1.º e 2.º trimestres, respectivamente vs. 47.4% antes da gravidez). Com a gravidez, não se verificaram alterações no tempo médio em diferentes tipos de actividade física, mas a actividade física no lazer registou uma diminuição significativa no 1.º trimestre face ao período anterior à concepção. Em comparação com uma amostra normativa de mulheres portuguesas, as grávidas apresentam, nos dois primeiros trimestres de gestação, uma percepção de qualidade da vida mais positiva na generalidade das dimensões do SF-36. No 2.º trimestre, o nível de limitação é significativamente maior nas dimensões físicas, à excepção da Dor Corporal, e nos resultados sumários do Componentes Físico e Mental. As mulheres que no 1.º trimestre atingem os níveis recomendados de actividade física no lazer (≥150 minutos por semana) apresentam melhor estado de saúde geral e estados de humor mais positivos do que as menos activas. Conclusão: A actividade física no lazer, embora diminua após a concepção, tem um impacto positivo na percepção do estado saúde geral e estados de humor da grávida, o que sugere a sua importância para a saúde da mulher também durante este período da vida.
