A novel approach to surface electromyography: An exploratory study of electrode-pair selection based on signal characteristics
A 3×4 electrode array was placed over each of seven muscles and surface electromyography (sEMG) data were collected during isometric contractions. For each array, nine bipolar electrode pairs were formed off-line and sEMG parameters were calculated and evaluated based on repeatability across trials and comparison to an anatomically placed electrode pair. The use of time-domain parameters for the selection of an electrode pair from within a grid-like array may improve upon existing electrode placement methodologies
Factores psicosociales asociados a un alto, medio y bajo riesgo de síntomas depresivos en el posparto inmediato Psychosocial factors associated to low, medium and high risk of depressive symptoms in the immediate postpartum period
OBJETIVOS: evaluar factores psicosociales asociados a síntomas depresivos en el posparto inmediato. MÉTODOS: 45 mujeres puérperas de un hospital público de Buenos Aires, Argentina, fueron entrevistadas entre el 1er y el 3er día posparto, de marzo-diciembre 2010. La Escala de Depresión Posnatal de Edimburgo (EPDS) fue administrada para evaluar síntomas depresivos. La entrevista psicológica perinatal (EPP) fue administrada para detectar variables psicosociales. A partir de los resultados obtenidos en la EPDS, se separó la muestra en tres grupos con diferentes grados de riesgo de sintomatología depresiva: "negativas o de bajo riesgo", "positivas de riesgo medio" y "positivas de alto riesgo". Los puntajes de corte utilizados fueron 9 y 19. RESULTADOS: se encontraron diferencias significativas entre los tres grupos con violencia familiar, migración, historia previa de depresión, presencia de síntomas depresivos durante el embarazo y mayor cantidad de estresores. CONCLUSIONES: el establecimiento de los dos puntajes de corte en la EPDS permite una detección temprana de las mujeres que presentan síntomas depresivos. Se sugiere la utilidad del puntaje de corte de 19 para la detección temprana de mujeres con mayor riesgo de desarrollar depresión posparto.<br>OBJECTIVES: evaluate psychosocial factors associated to depressive symptoms during the immediate postpartum period. METHODS: a total of 45 argentine puerperal women hospitalized in a public maternal hospital of Buenos Aires, Argentina, were interviewed on the 1st and 3rd day postpartum from March to December 2010. Aiming to assess the presence of depressive symptoms, the Edinburgh Postnatal Depression Scale (EPDS) was administrated. The Perinatal Psychological Interview was administrated to explore psychosocial variables. Based on the scores obtained in the EPDS, the sample was separated in three different groups with increasing risk of depressive symptomatology: "negative or low risk", "positive medium risk" and "positive high risk". Cut-off scores were 9 and 19 points. RESULTS: out of the total psychosocial variables analyzed, statistically significant differences were found among the three groups regarding family violence, migration, previous history of depression, depressive symptoms during pregnancy and increasing number of life events. CONCLUSIONS: the setting of two cut-off scores in EPDS allows the early detection of women with depressive symptoms. It is suggested the usefulness of cut-off value of 19 for early detection of women at high risk to developing postpartum depression
Timely access and quality of care in colorectal cancer: a population-based cohort study using administrative data
The DSM diagnostic criteria for Female Sexual Arousal Disorder
This article reviews and critiques the DSM-IV-TR diagnostic criteria for Female Sexual Arousal Disorder (FSAD). An overview of how the diagnostic criteria for FSAD have evolved over previous editions of the DSM is presented and research on prevalence and etiology of FSAD is briefly reviewed. Problems with the essential feature of the DSM-IV-TR diagnosis — “an inability to attain, or to maintain…an adequate lubrication-swelling response of sexual excitement” — are identified. The significant overlap between “arousal” and “desire” disorders is highlighted. Finally, specific recommendations for revision of the criteria for DSM-V are made, including use of a polythetic approach to the diagnosis and the addition of duration and severity criteria
