There is a death risk that increases with the required time to transport a critical patient to a hospital by ambulance. Effectiveness of medical attention and therefore patient's safety will strongly depend on the quickness to determine appropriate actions to be performed when patient arrives to the hospital. It is evident the need of establishing a communication link between monitoring equipment inside the ambulance and the healthcare center. This paper presents a system that automatically integrates, organizes, records and wirelessly transmits patient's vital signs in real-time. Physicians and specialists could use this information to make a pre-diagnosis of patient's current condition, anticipate possible complications and medical treatment planning before his arrival to the care center.

Gait analysis is the systemic study of human walking. In this paper we present the development of a 3D gait analysis system based on Augmented Reality (AR). AR allows a user to see a real world with virtual elements overlapped upon it in real time. To build the 3D Gait Analysis system was necessary to determine markers position for gait analysis, develop an electronic circuit with Arduino technology to control accelerometers and infrared leds to feed the virtual 3D scene, develop human-machine interface to establish a communication protocol between the electronic circuit and the computer and generate augmented reality based on accelerometers and infrared leds.

Mechanical ventilation (MV) is a clinical therapy that becomes necessary when the ventilatory capacity of patients is depressed by pathophysiological reasons or post-surgery conditions like cardiac surgery. 22.7% of patients undergoing cardiac surgery require mechanical ventilation over 24 to 48 hours. [1]. In these patients, the mortality rate may exceed 40%. It is known that the main cause of failure in weaning is an imbalance between the ability of respiratory muscles, mechanical ventilation and respiratory controller actions. This paper presents the assessment of respiratory muscles coupling as an indicator of work of breathing in mechanically ventilated cardiovascular postoperative patients. The approach includes correlograms and multichannel singular spectrum analysis of diaphragm, intercostal and sternocleidomastoid, showing that over 70% of cases had linear and nonlinear coupling between muscles. Patients that had a failed weaning also presented high muscle coupling probably due to the ventilator settings.

Melanoma represents one of most malignant tumors associated with melanocytes in pigmented cells of the skin and in particular is a result of malignant transformation of melanocytes. Due to migration of neural cell crest, melanoma can develop not only on skin, but on oral and genital mucosa, and also gastrointestinal tract and brain. Melanoma is usually present and manifests itself with changes in color, size, contour and configuration, or may occur as new pigmented lesions. In particular, melanoma represents the sixth leading cause of malignancy in the United States with much higher mortality rate among non-Caucasian population, although is more common among whites. Considering its complexity, clinical diagnosis of melanoma is challenging even for experienced dermatologists. This is why it is necessary to develop computer assisted diagnostic tool for melanoma detection focused on dark and fair complexion skin which adds more objective judgments based on quantitative measures. Therefore, specialized algorithms were developed and tested utilizing databases including images of a variety of skin cancer manifestations. Those diagnostic indicators were assessed utilizing commonly used ABCDE criteria for different skin complexions and also natural and simulated darker background reflecting darker skin tones associated with different ethnic groups. Incorporated Canny, Prewitt, Roberts and Sobel edge detectors allowed to optimize melanoma diagnosis for darker skin tones and assess the degree of correct classification for each of ABCDE criterion reflecting varied skin complexion.

Development of electrospun scaffolds for tissue engineering vascular grafts requires the integration of well differentiated and complementary disciplines. The aim of present work is to describe a cooperative experience in biomedical research developed between academic institutions of Argentina and Uruguay. Electrospinning technique, high resolution ultrasound in-vitro measurements and signal processing algorithms were implemented in order to characterize and improve the mechanical response of mono and bi-layered polymeric structures. Each stage of the process was defined based on the maximal capabilities and expertise of each laboratory, thus optimizing the available resources.

Artificial heart valves are used to replace diseased heart valves [1]. Accurate performance of the valve includes a right opening and closing process of the valves during each heartbeat. Recent studies focus on 3D computational models for commercial valvular prosthesis in non-stationary conditions for non-Newtonian Fluids [2]. However, lifespan of mechanical valves needs to be improved. The main goal of this study was to evaluate three novel geometries for mitral valve replacement using computational fluid dynamics (CFD). Our findings show that cylindrical trileaflet valve has the best performance and could be suitable for mitral valve replacement.

Individuals with stroke and other central nervous damage, which may cause paresis, are unable to move their affected limb or the movements are inefficient and clumsy. Brain-computer interfaces coupled with robotic assistive technologies such as robotic hand orthosis have the potential to provide rehabilitation strategies that promote brain plasticity for these patients. This paper presents the design of a control signal based on EEG signal processed using common spatial patterns and linear discriminant analysis to identify hand motor imagery. The control signal is implemented on a robotic hand orthosis so that it activates when a healthy subject performs motor imagery of her/his right hand, simulating an online signal acquisition. The mechatronic orthosis performance was always as indicated by the control signal, and the systems online performance for detecting motor imagery was of nearly 80% of correct classification. The system may be improved by using other classification algorithms however results show that it is ready to be tested with motor impaired patients.
