A Survey of Canadian Massage Therapists Experiences of Work-Related Pain.

An investigation into the work-related pain (WRP) experienced by Massage Therapists (MTs) in Ontario, Canada was undertaken using voluntary completion of an online questionnaire following broad distribution of requests to take part in this study. Data from respondents were included for analysis if they provided informed consent and were a currently or previously registered MT in the region. With voluntary participation, self-selection respondent bias must be considered in evaluating reported results.

Advanced Electrocardiography Identifies Left Ventricular Systolic Dysfunction in Non-Ischemic Cardiomyopathy and Tracks Serial Change over Time.

Unlabelled: Electrocardiogram (ECG)-based detection of left ventricular systolic dysfunction (LVSD) has poor specificity and positive predictive value, even when including major ECG abnormalities, such as left bundle branch block (LBBB) within the criteria for diagnosis. Although machine-read ECG algorithms do not provide information on LVSD, advanced ECG (A-ECG), using multiparameter scores, has superior diagnostic utility to strictly conventional ECG for identifying various cardiac pathologies, including LVSD.

Methods: We evaluated the diagnostic utility of A-ECG in a case-control study of 40 patients with LVSD (LV ejection fraction < 50% by echocardiography), due to non-ischemic cardiomyopathy (NICM), and 39 other patients without LVSD.
