A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

A Return to Normality: A Descriptive Qualitative Interview Study Exploring the Patient Experience of Gout Flare Resolution

Arthritis Care &Research, EarlyView.
Objective Although the definition of a gout flare is well established, the state of gout flare resolution has not yet been defined. This study aimed to explore patients’ experiences and perceptions of gout flare resolution. Methods Semistructured interviews were conducted with 24 people with gout, guided by open‐ended questions exploring their ...

Improving the dry sliding-wear resistance of as-cast Cu-10Sn-1P alloy through accumulative back extrusion (ABE) process

Journal of Materials Research and Technology, 2020
In this study, the as-cast Cu-10Sn-1P alloy was subjected to multi-pass (1–3 passes) accumulative back extrusion (ABE) process. Also, the effects of the process were investigated on microstructure and dry sliding wear behavior.

Role of Wear Particles in Severe-Mild Wear Transition.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1992
The mechanism of severe-mild wear transition and the role of wear particles in that process are studied using a pin-on-disk type wear test rig. Wear particles are continuously removed by air pressure. With the removal of wear particles, severe-mild wear transition does not occur.
