Overactive bladder syndrome was prevalent among older women and the existence of these symptoms was linked to the presence of mild, moderate and/or severe anxiety symptoms.

BackgroundStudies demonstrate an association between severe depression and overactive bladder syndrome (OAB). However, mild depression is constantly overlooked. The aim of this study was to evaluate the clinical and sociodemographic factors associated with mild depression in women with OAB. MethodsCross-sectional study involving 241 women over 60 years old in Brasilia, Brazil. All patients were subjected to an interview followed by questionnaires and physical examination. The clinical and sociodemographic variables analyzed were age, body mass index, physical activity level, OAB symptoms, presence of gynecological surgery, fecal incontinence, systemic arterial hypertension, Diabetes Mellitus, anxiety (Beck Anxiety Scale). The Geriatric Depression Scale-15 (GDS-15) was used to identify depression. Univariate logistic regression was used to assess the correlation between mild depression and the variables chosen. Variables with a p-value less than 0.2 were included in the multivariate logistic regression analysis. The level of confidence was set at 95%. Results121 volunteers suffered from mild depression. The multivariate analysis demonstrated that gynecological surgery (p < .001) and anxiety (p < .001) are factors associated with mild depression. Older women with a history of gynecological surgery and a GDS-15 score of 2.04 were 1.08 times more likely to develop mild depression compared to older women with no history of gynecological surgery.

RESUMOIntrodução: A população de idosos representa 10% do total da população brasileira. A diminuição da musculatura esquelética é provavelmente a alteração mais significativa, sendo associada à idade e algumas enfermidades, e é determinante na perda da força muscular. Objetivo: Avaliar a relação entre composição corporal e a força de preensão palmar de homens idosos brasileiros. Método: Quarenta e seis homens com idade igual ou superior a 60 anos foram divididos em 4 grupos de acordo com a percentagem de gordura e valor de massa magra. Foram definidas as medianas para %G = 28,65 e massa magra = 54,35 kg. Para as avaliações utilizou-se teste de bioimpedância elétrica e dinamômetro de preensão palmar. Resultados: Observam-se diferenças significativas entre os quatro grupos quanto à massa magra e percentil de massa gorda (p≥0,05), caracterizando as especificidades de cada grupo quanto às variáveis analisadas. Conclusão: Os resultados demonstram que os níveis de força de preensão palmar não dependem unicamente da massa magra, mas também %G, em que a correlação entre massa magra e percentual de gordura pode indicar uma melhor ou pior condição para realizar o esforço isométrico de preensão manual.Palavras-chave: idoso, força da mão, composição corporal. ABSTRACT Introduction: The senior population constitutes 10% of the total Brazilian population. The decrease of skeletal muscle is probably the most significant alteration, being associated with age and some illnesses, and it is determinant in the loss

Summary This article proposes a comparison between mathematical modeling and experimental results of the electric interactions of a synchronous and an induction generator. The electric system is composed by a synchronous generator operating in parallel with the induction generator, both through a common bus, connected to nonlinear loads. Measurements are made at several points for different system configurations presenting the repowering effect. The analysis of the harmonic flow and the sensitivity of the system parameters are performed. To make predictions in the system, a validated computational model with experimental data is proposed. The results obtained comparing the mathematical modeling and experimental tests show the increase of the active power by the induction generator, as well as the circulation of harmonic currents in the common bus. The results obtained through the computational model present predictions of load unbalance and increase in the system harmonic distortions. The sensitivity analysis confirms the induction generator influences on the system harmonic flow.
