Semantic context consolidation and rule learning for optimized transport assignments in hospitals

The increase of ICT infrastructure in hospitals offer opportunities for cost reduction by optimizing workflows, while maintaining quality of care. This work-in-progress poster details the AORTA system, which is a semantic platform to optimize transportation task scheduling and execution in hospitals. It provides a dynamic scheduler with an upto-date view about the current context by performing semantic reasoning on the information provided by the available software tools and smart devices. Additionally, it learns semantic rules based on historical data in order to avoid future delays in transportation time

Context-Aware and Self-learning Dynamic Transport Scheduling in Hospitals

The increase in available ICT infrastructure in hospitals offers cost reduction opportunities by optimizing various workflows, while maintaining quality of care. In this demonstrator-paper, we present a self-learning dashboard, for monitoring and learning the cause of delays of hospital transports. By identifying these causes, future delays in transport time can be reduced.status: publishe

Ivory Arthroplasty for Trapeziometacarpal Joint Arthritis in Men:Analysis of Clinical Outcome and Implant Survival

Background: Trapeziometacarpal arthroplasties are designed to restore an adequate level of mobility, stability, and grip strength. In this article, pain and functional and radiographic outcome of Ivory arthroplasty in male patients are investigated. Methods: Between 2005 and 2012, the Ivory arthroplasty was inserted in 21 male patients with degenerative trapeziometacarpal osteoarthritis, of which 14 patients were found eligible for inclusion. Mobility, grip strength, patient self-assessment (pain; Quick Disabilities of the Arm, Shoulder, and Hand [QuickDASH]), and radiographic outcome were measured. Twenty-two female patients who received an Ivory arthroplasty between 2005 and 2007 were included and underwent the same evaluation. Age at primary surgery, survival rate of the implant, and clinical outcome were compared between the 2 groups. Results: In both groups, QuickDASH score and mean pain sensation improved significantly. The improvement in mobility obtained significance in the female group. In the male group, 7 arthroplasties failed (mean follow-up of 65 months). In the female group, 3 of the 24 arthroplasties failed (mean follow-up of 123 months). Kaplan-Meier survival analysis demonstrated a significant lower implant survival in the male group. Conclusions: Decrease in muscle mass and decline in grip strength that postmenopausal women tend to experience might explain the significant difference in implant survival between sexes. In 4 of the 7 failed arthroplasties in the male group, no surgical revision was required. Trapeziometacarpal arthroplasty, even after radiographic failure, still served as a spacer, avoiding collapse of the thumb base. Nevertheless, the failure rate of the Ivory arthroplasty in male patients is high, and an alternative treatment should be considered

Myhre syndrome : a first familial recurrence and broadening of the phenotypic spectrum

Myhre syndrome is a rare multisystem connective tissue disorder, characterized by short stature, facial dysmorphology, variable intellectual disability, skeletal abnormalities, arthropathy, cardiopathy, laryngotracheal anomalies, and stiff skin. So far, all molecularly confirmed cases harbored a de novo heterozygous gain-of-function mutation in SMAD4, encoding the SMAD4 transducer protein required for both transforming growth factor-beta and bone morphogenic proteins signaling. We report on four novel patients (one female proband and her two affected children, and one male proband) with Myhre syndrome harboring the recurrent c.1486C>T (p.Arg496Cys) mutation in SMAD4. The female proband presented with a congenital heart defect, vertebral anomalies, and facial dysmorphic features. She developed severe tracheal stenosis requiring a total laryngectomy. With assisted reproductive treatment, she gave birth to two affected children. The second proband presented with visual impairment following lensectomy in childhood, short stature, brachydactyly, stiff skin, and decreased peripheral sensitivity. Transmission electron microscopy (TEM) of the dermis shows irregular elastin cores with globular deposits and almost absent surrounding microfibrils and suggests age-related increased collagen deposition. We report on the first familial case of Myhre syndrome and illustrate the variable clinical spectrum of the disorder. Despite the primarily fibrotic nature of the disease, TEM analysis mainly indicates elastic fiber anomalies
