A multi-purpose force-controlled loading device for cartilage and meniscus functionality assessment using advanced MRI techniques.

Response to loading of soft tissues as assessed by advanced magnetic resonance imaging (MRI) techniques is a promising approach to evaluate tissue functionality beyond (statically obtained) structural and compositional features. As cartilage and meniscus pathologies are closely intertwined in osteoarthritis (OA) and beyond, both tissues should ideally be studied to elucidate further the underlying...

Mechanical effects of MitraClip on leaflet stress and myocardial strain in functional mitral regurgitation - A finite element modeling study.

MitraClip is the sole percutaneous device approved for functional mitral regurgitation (MR; FMR) but MR recurs in over one third of patients. As device-induced mechanical effects are a potential cause for MR recurrence, we tested the hypothesis that MitraClip increases leaflet stress and procedure-related strain in sub-valvular left ventricular (LV) myocardium in FMR associated with coronary disea...

Non-medical cannabis in North America: an overview of regulatory approaches.

The objective of this study was to describe existing regulations of non-medical cannabis legalization in North America to inform recommendations for future health policy. These regulations are among the first in the world and will set a precedent for other jurisdictions globally who legalize cannabis.

The correlation between smart device usage & sleep quality among UAE residents.

The usage of smart-devices has increased considerably both globally and specifically in Middle Eastern countries. Recently, it has been shown that 65% of United Arab Emirates (UAE) residents lack proper sleep. Several health aspects of the relationship between over usage of smart-devices and poor sleep quality have not been thoroughly investigated. This study aims to determine the correlation betw...

Prostate Cancer Detection Rate of Free-hand versus 3D Template Mapping Biopsy Using an MRI/Ultrasound Fusion Device in Biopsy-Naïve Men.

Targeted prostate biopsy devices include a 3-dimensional digital template grid for guiding systematic biopsy locations. Following a template could better ensure uniform and well-distributed sampling of the prostate compared to the traditional free-hand biopsy approach, possibly decreasing the chance for false-negative biopsy. Thus, we determined cancer detection rates obtained by conventional free...

Medical Methods: What Makes them Medically Necessary? Part II: Further Criteria, Overuse, Moving Thresholds, and Grey Zones.

"Medical necessity" (MedN) is a fuzzy term. Our project aims at concretising the concept between medical ethics, social law, and social medicine to support health care regulation, primarily within Germany's statutory health insurance system. In Part I, we identified efficacy, (net)benefit, and the corresponding bodies of evidence as obligatory criteria of MedN. This is the second part suggesting a...
