Effective Brief, Low-impact, High-intensity Osteogenic Loading in Postmenopausal Osteoporosis.

Background: Osteoporosis is characterized by reduced bone mineral density (BMD) and disrupted microarchitecture estimated by trabecular bone score (TBS), resulting in increased bone fracture risk. "Osteostrong®" is a bone-strengthening system implementing 4 devices and incorporating brief (10-minute), weekly, low-impact, and high-intensity osteogenic loading exercises. We evaluated the efficacy of the Osteostrong® intervention in postmenopausal osteoporotic women.

Complementarity between Bayesian Internal Quality Control results management and External Quality Assessment bivariate z-score analysis: application to a concrete case study.

It is important that a clinical laboratory has implemented appropriate procedures for quality control, which includes both internal quality control (IQC) and external quality assessment (EQA) with the common goal to detect systematic errors and random errors. It is the case for both the Hemohub® Bayesian tools for IQC results interpretation and the ECAT EQA optimised bivariate z-scores analysis. On a concrete case study, we demonstrate both the higher sensitivity and specificity of optimised bivariate z-scores analysis than the univariate approach.

Let UNet Play an Adversarial Game: Investigating the Effect of Adversarial Training in Enhancing Low-Resolution MRI.

Adversarial training has attracted much attention in enhancing the visual realism of images, but its efficacy in clinical imaging has not yet been explored. This work investigated adversarial training in a clinical context, by training 206 networks on the OASIS-1 dataset for improving low-resolution and low signal-to-noise ratio (SNR) magnetic resonance images. Each network corresponded to a different combination of perceptual and adversarial loss weights and distinct learning rate values.

An Actuated Variable-View Rigid Scope System to Assist Visualization in Diagnostic Procedures.

Objective: Variable-view rigid scopes offer advantages compared to traditional angled laparoscopes for examining a diagnostic site. However, altering the scope's view requires a high level of dexterity and understanding of spatial orientation. This requires an intuitive mechanism to allow an operator to easily understand the anatomical surroundings and smoothly adjust the scope's focus during diagnosis.
