Using the Rapid Upper Limb Assessment to examine the effect of the new Hotel Housekeeping California Standard.

A housekeeper's job includes a variety of repetitive and strenuous tasks, which can put workers at high risk for musculoskeletal disorders. In 2018, a new standard was implemented in California aiming to prevent work-related injuries of hospitality industry workers. This paper assesses California housekeepers performing regular work tasks during their shifts from 2018 to 2020.

Association between calcifications of mitro-aortic continuity and mitral regurgitation in patients undergoing transcatheter aortic valve replacement.

Background: The presence of mitral annular calcification (MAC) affects prognosis in patients undergoing transcatheter aortic valve implantation (TAVI). MAC frequently coexists with calcifications of mitro-aortic continuity (CMAC).

Aims: We aimed at qualitative and semi-quantitative analysis of calcifications of the mitral complex - MAC and CMAC in multi-slice computed tomography, in order to assess their impact on the occurrence and dynamics of mitral regurgitation (MR) following TAVI.

Comparison of the geometry of the left ventricle outflow tract, the aortic root and the ascending aorta in patients with severe tricuspid aortic stenosis versus healthy controls.

The purpose of this study was to assess by multislice computed tomography (MSCT) imaging geometry of the ascending aorta, the aortic root, the aortic annulus and the left ventricle outflow tract (LVOT) in aortic stenosis (AS) patients, to compare aortic root morphology in patients with AS with healthy controls and to evaluate sex differences. Fifty patients with severe AS and 50 age- and gender-matched controls who underwent MSCT were included in the study. The dimensions of the LVOT, the aortic annulus, the aortic root, the ascending aorta, and the volume of the aortic root were retrospectively assessed and a comparison was made between patients with severe tricuspid AS and controls.

Predictors of aortic stenosis severity reclassification using an imaging data fusion method in patients referred for transcatheter aortic valve implantation.

Background: The use of imaging data fusion method (IDFM) with multislice computed tomography (MSCT) and two-dimensional transthoracic echocardiography (2D-TTE) in patients with aortic stenosis (AS) may result in reclassification of AS severity from severe to non-severe.

Aim: We sought to establish potential predictors of AS severity reclassification using the IDFM method.

Methods: A total of 54 high-risk patients (mean age 79 ± 7.

Quantitative estimation of aortic valve calcification in multislice computed tomography in predicting the development of paravalvular leaks following transcatheter aortic valve replacement.

Introduction: Transcatheter aortic valve implantation (TAVI) improves prognosis in patients disqualified from surgical valve replacement. Calcifications of the aortic complex can lead to deformation of the prosthesis, resulting in paravalvular leaks (PVL).

Aim: To evaluate the predictive value of quantitative estimation of volume/weight and geometric distribution of calcifications in multislice computed tomography, for the development of PVL.

Evaluation of overhead guide sign sheeting materials to increase visibility and safety for drivers.

Overhead guide sign visibility must increase to improve driver safety on roadways. Two methods increase overhead guide sign visibility: sign illumination and use of retroreflective sheeting materials. This paper compares three types of retroreflective sheeting: Engineering Grade (type I), Diamond Grade (type XI), and High Intensity (type IV).
