Metabolic Cost and Mechanical Efficiency of a Novel Handle-Based Device for Wheelchair Propulsion.

Objective: To investigate differences in metabolic cost and gross mechanical efficiency of a novel handlebased wheelchair propulsion device and to compare its performance with conventional push-rim propulsion.

Design: Double-group comparative study between 2 different propulsion methods.

Participants: Eight paraplegic individuals and 10 non-disabled persons.

Ivermectin treatment in rosacea: How novel smartphone technology can support monitoring rosacea-associated signs and symptoms.

Rosacea lessens patients' quality of life not only by visible symptoms like erythema, papules, and pustules but also by invisible symptoms like stinging, burning, and dryness. Ivermectin 1% cream has recently been introduced as an efficient therapy for papules and pustules in rosacea patients. To investigate the potential of ivermectin 1% cream to improve rosacea-associated erythema and invisible symptoms by combining established questionnaires with the novel photography and analysis tool Scarletred®Vision.

The mathematics of erythema: Development of machine learning models for artificial intelligence assisted measurement and severity scoring of radiation induced dermatitis.

Although significant advancements in computer-aided diagnostics using artificial intelligence (AI) have been made, to date, no viable method for radiation-induced skin reaction (RISR) analysis and classification is available. The objective of this single-center study was to develop machine learning and deep learning approaches using deep convolutional neural networks (CNNs) for automatic classification of RISRs according to the Common Terminology Criteria for Adverse Events (CTCAE) grading system. Scarletred Vision, a novel and state-of-the-art digital skin imaging method capable of remote monitoring and objective assessment of acute RISRs was used to convert 2D digital skin images using the CIELAB color space and conduct SEV* measurements.

Wrist Kinematics and Kinetics during Wheelchair Propulsion with a Novel Handle-based Propulsion Mechanism.

Wheelchairs are important for daily mobility and recreation of the elderly and physically challenged individuals. The non-ergonomical propulsion design of wheelchairs frequently causes injuries to the upper extremities, especially in the wrist region. In this study, the joint kinematics and kinetics of the wrist joint was analyzed on subjects propelling a novel handle based wheelchair propulsion unit at 1.
