Effectiveness of whole-exome sequencing and costs of the traditional diagnostic trajectory in children with intellectual disability
PURPOSE: This study investigated whole-exome sequencing (WES) yield in a subset of intellectually disabled patients referred to our clinical diagnostic center and calculated the total costs of these patients' diagnostic trajectory in order to evaluate early WES implementation. METHODS: We compared 17 patients' trio-WES yield with the retrospective costs of diagnostic procedures by comprehensively examining patient records and collecting resource use information for each patient, beginning with patient admittance and concluding with WES initiation. We calculated cost savings using scenario analyses to evaluate the costs replaced by WES when used as a first diagnostic tool. RESULTS: WES resulted in diagnostically useful outcomes in 29.4% of patients. The entire traditional diagnostic trajectory average cost was 3,972 trio-WES cost. WES resulted in average cost savings of 1,727 for genetic investigations in undiagnosed patients. CONCLUSION: The increased causal variant detection yield by WES and the relatively high costs of the entire traditional diagnostic trajectory suggest that early implementation of WES is a relevant and cost-efficient option in patient diagnostics. This information is crucial for centers considering implementation of WES and serves as input for future value-based research into diagnostics

Selective Activation of KCa3.1 and CRAC Channels by P2Y2 Receptors Promotes Ca2+ Signaling, Store Refilling and Migration of Rat Microglial Cells
Ion Channels in Glioma Malignancy
Brain tumors come in many types and differ greatly in outcome. They are classified by the cell of origin (astrocytoma, ependymoma, meningioma, medulloblastoma, glioma), although more recently molecular markers are used in addition to histology. Brain tumors are graded (from I to IV) to measure their malignancy. Glioblastoma, one of the most common adult primary brain tumors, displays the highest malignancy (grade IV), and median survival of about 15 months. Main reasons for poor outcome are incomplete surgical resection, due to the highly invasive potential of glioblastoma cells, and chemoresistance that commonly develops during drug treatment. An important role in brain tumor malignancy is played by ion channels. The Ca2+-activated K+ channels of large and intermediate conductance, KCa3.1 and KCa1.1, and the volume-regulated anion channel, whose combined activity results in the extrusion of KCl and osmotic water, control cell volume, and in turn migration, invasion, and apoptotic cell death. The transient receptor potential (TRP) channels and low threshold-activated Ca (T-type) channels have equally critical role in brain tumor malignancy, as dysregulated Ca2+ signals heavily impact on glioma cell proliferation, migration, invasion. The review provides an overview of the current evidence involving these channels in brain tumor malignancy, and the application of these insights in the light of future prospects for experimental and clinical practice
