In this research we developed an alarm system that enables assistance dogs to call for help on behalf of their vulnerable owners in an emergency, involving the end users (both assistance dogs and their owners) directly in the entire design process. Here we present a high-fidelity prototype of a user-friendly canine alarm system. In developing the system, we(More)
Motivated by the need of poor and rural Mexico, where the population has limited access to advanced medical technology and services, we have developed a new paradigm for medical diagnostic based on the technology of "Volumetric Electromagnetic Phase Shift Spectroscopy" (VEPS), as an inexpensive partial substitute to medical imaging. VEPS, can detect changes(More)
In this paper we discuss the role of mobility assistance dogs in human society and the challenges they face when operating in human environments. We present the findings of an ethnographic study at a training facility as well as the findings of early evaluations of canine-friendly switches. We discuss how the species-specific implementation of core(More)
INTRODUCTION AND OBJECTIVE Patients with lesions of the proximal left anterior descending coronary artery are a special high-risk group. In the present study we analyzed the efficacy and safety of coronary stenting in such lesions and the factors related to a less favorable prognosis in long-term follow-up. METHODS Ninety-eight consecutive patients with(More)
BACKGROUND Renal impairment is a well-known risk factor for cardiovascular complications, but the effect of different stages of renal impairment on thrombotic/thromboembolic and bleeding complications in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) remains largely unknown. We sought to evaluate the incidence and(More)
INTRODUCTION AND OBJECTIVES Several registries of acute myocardial infarction (AMI) have been carried out in Spain, but few remain active. This work analyses the evolution of the characteristics and control of patients with AMI during the first 10 years of the PRIMVAC registry, initiated in 1995. METHODS The demographical and clinical characteristics,(More)
Sirolimus-eluting stents (SES) have demonstrated low incidence of target vessel revascularizations in several anatomic scenarios, including proximal left anterior descending coronary artery (pLAD) lesions. The aim of present study was to compare the efficacy of SES with bare metal stents (BMS) for the treatment of such lesions. 96 patients with severe pLAD(More)
Spontaneous coronary artery dissection is a rare condition that may produce severe myocardial ischemia. The growth of indications for cardiac catheterization have led to an increment in the number of cases identified in patients with acute coronary syndromes. Because the therapeutic approach and prognosis are uncertain, doubts often arise regarding the(More)
