Abstract Background Coronary artery disease (CAD) confers increased risks of premature mortality, non-fatal morbidity, and significant impairment in functional status and health-related quality of life. Routine administration of electronic patient-reported outcome measures (PROMs) and its real time delivery to care providers is known to have the potential to inform routine cardiac care and to improve quality of care and patient outcomes. This study describes a user-centered development and evaluation of the Alberta Provincial Project for Outcomes Assessment (APPROACH) electronic Patient Reported Outcomes Measurement (e-PROM) system. This e-PROM system is an electronic system for the administration of PROMs to patients with CAD and the delivery of the summarized information to their care providers to facilitate patient-physician communication and shared decision-making. This electronic platform was designed to be accessible via web-based and hand-held devices. Heuristic and user acceptance evaluation were conducted with patients and attending care providers. Results The APPROACH e-PROM system was co-developed with patients and care providers, research investigators, informaticians and information technology experts. Five PROMs were selected for inclusion in the online platform after consultations with patient partners, care providers, and PROMs experts: the Seattle Angina Questionnaire, Patient Health Questionnaire, EuroQOL, and Medical Outcomes Study Social Support Survey, and Self-Care of Coronary Heart Disease Inventory. The heuristic evaluation was completed by four design experts who examined the usability of the prototype interfaces. User acceptance testing was completed with 13 patients and 10 cardiologists who evaluated prototype user interfaces of the e-PROM system. Conclusion Both patients and physicians found the APPROACH e-PROM system to be easy to use, understandable, and acceptable. The APPROACH e-PROM system provides a user-informed electronic platform designed to incorporate PROMs into the delivery of individualized cardiac care for persons with CAD.

This paper introduces wav2letter++, the fastest open-source deep learning speech recognition framework. wav2letter++ is written entirely in C++, and uses the ArrayFire tensor library for maximum efficiency. Here we explain the architecture and design of the wav2letter++ system and compare it to other major open-source speech recognition systems. In some cases wav2letter++ is more than 2x faster than other optimized frameworks for training end-to-end neural networks for speech recognition. We also show that wav2letter++'s training times scale linearly to 64 GPUs, the highest we tested, for models with 100 million parameters. High-performance frameworks enable fast iteration, which is often a crucial factor in successful research and model tuning on new datasets and tasks.

The mechanisms underlying astrocyte heterogeneity in the developing mouse brain are poorly understood. The bHLH transcription factor Olig2 is essential for motoneuron and oligodendrocyte formation; however, its role in astrocyte development remains obscure. During cortical development, Olig2 is transiently expressed in immature developing astrocytes at neonatal stages and is progressively downregulated in astrocytes at late postnatal stages. To assess the function of Olig2 in astrocyte formation, we conditionally ablated Olig2 in a spatiotemporally controlled manner. In the Olig2-ablated cortex and spinal cord, the formation of astrocytes in the white matter is severely compromised. Temporally controlled mutagenesis revealed that postnatal Olig2 function is required for astrocyte differentiation in the cerebral white matter. By contrast, astrocytes in the cortical gray matter are formed, but with sustained GFAP upregulation in the superficial layers. Cell type-specific mutagenesis and fate-mapping analyses indicate that abnormal astrocyte formation is at least in part attributable to the loss of Olig2 in developing astrocytes and their precursors. Thus, our studies uncover a crucial role for Olig2 in white matter astrocyte development and reveal divergent transcriptional requirements for,and developmental sources of, morphologically and spatially distinct astrocyte subpopulations.

Objectives: To advocate for independent pharmacy to embrace digital health as a means to improve patient outcomes and compete more strongly in an increasingly competitive business environment. Summary: Independent pharmacies are positioned to be at the forefront of adopting digital health tools for a variety of reasons. They often can make changes to their business model faster than a major retail chain, are often in rural locations where few other providers are located, and are already starting to offer the types of clinical services that can be greatly aided by digital health. This commentary presents the case for a change in the current model of pharmacy practice to one which embraces digital health. The role of the pharmacist would grow beyond exclusively medication management to incorporate tools such as wearable health trackers and mobile phone applications. By utilizing digital health, the pharmacist can obtain a greater amount of patient health data via an asynchronous electronic uploading process, and then use that data to further improve their ability to offer clinical services. Conclusion: Digital health is a powerful tool that should be embraced by independent pharmacy. By leveraging digital health, pharmacies can improve both accessibility and quality of care, thus providing a competitive advantage in the retail marketplace. Article Type: Commentary
