Two cases with a concealed left-sided accessory atrioventricular bypass tract are described. In both, functional longitudinal dissociation of the atrioventricular node narrowed the range of atrial premature beat coupling intervals which could initiate re-entry using the accessory pathway. In case 1 early premature atrial beats were followed by an atrioventricular nodal re-entrant echo. The atri...

Conservative treatment is ineffective for ossification of the posterior longitudinal ligament (OPLL) in the thoracic spine, and surgical treatment is indicated for most cases, while such cases are not often experienced. In the present study, the results of surgical management involving mainly posterior decompression for this disease were evaluated clinically. The study included 9 patients (1 ma...

Background: Previous research shows that the Student Well-being Process Questionnaire (Student WPQ) has good content validity, construct validity, and discriminate validity. Objective: The present research examined the reliability and predictive validity of the Student WPQ scales. Method: Eighty-seven university undergraduate and postgraduate students aged 18-47 years participated in a longitud...

Understanding the dynamics of hyporheic flow is important for managing water resources, since this interfacial exchange affects fate and transport contaminants in rivers. This study numerically quantifies effect on solute residence times surface systems by simulating unified turbulent open-channel zone systems. Interfacial fluxes (qint) increase with increased Reynolds number (Re) that produces...

This paper re-examines evidence relating mean inflation to cross-sectional inflation asymmetry, and investigates longitudinal asymmetry in disaggregated price series. The asymmetry test used possesses two important characteristics: it has high power, and it is not dominated by outliers. In contrast to Bryan and Cecchetti (1996), the results here suggest that there does exist significant positiv...

Background: In this study the longitudinal relationships between proactive / reactive aggression and autonomic nervous system (ANS) (re)activity were studied, as well as the moderating effect of posttraumatic stress disorder (PTSD) symptoms. Methods: Delinquent males were assessed twice over a 5-year period in adolescence. We related self-reported proactive/ reactive aggression and PTSD symptom...

Population-based, prospective longitudinal cohort studies are considering the issues surrounding returning findings to individuals as a result of genomic and other medical research studies. While guidance is being developed for clinical settings, the process is less clear for those conducting longitudinal research. This paper discusses work conducted on behalf of The UK Cohort and Longitudinal ...

This paper develops an accounting framework to consider the effect of deaths on the longitudinal analysis of income-related health inequalities. Ignoring deaths or using Inverse Probability Weights (IPWs) to re-weight the sample for mortality-related attrition can produce misleading results. Incorporating deaths into the longitudinal analysis of income-related health inequalities provides a mor...
