RESUMO
This study describes the development (design, construction, instrumentation, and control) of a nursing mobile robotic device to monitor vital signals in home-cared patients. The proposed device measures electrocardiography potentials, oxygen saturation, skin temperature, and non-invasive arterial pressure of the patient. Additionally, the nursing robot can supply assistance in the gait cycle for people who require it. The robotic device's structural and mechanical components were built using 3D-printed techniques. The instrumentation includes electronic embedded devices and sensors to know the robot's relative position with respect to the patient. With this information together with the available physiological measurements, the robot can work in three different scenarios: (a) in the first one, a robust control strategy regulates the mobile robot operation, including the tracking of the patient under uncertain working scenarios leading to the selection of an appropriate sequence of movements; (b) the second one helps the patients, if they need it, to perform a controlled gait-cycle during outdoors and indoors excursions; and (c) the third one verifies the state of health of the users measuring their vital signs. A graphical user interface (GUI) collects, processes, and displays the information acquired by the bioelectrical amplifiers and signal processing systems. Moreover, it allows easy interaction between the nursing robot, the patients, and the physician. The proposed design has been tested with five volunteers showing efficient assistance for primary health care. Graphical Abstract Main stages of the home-care nursing controlled mobile robot.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To evaluate the clinical efficacy of minimally invasive endoscopic surgery in patients with spinal extradural and intradural-extramedullary tumors. METHODS: This was a study of 15 consecutive patients with spinal extradural or intradural-extramedullary tumors up to 2 levels treated by minimal invasive surgery using a full endoscopic visualization and Caspar's retraction system (for cervical, thoracic, and lumbar tumors) over a 4-year period between January 2015 to April 2019 at a tertiary center. RESULTS: A gross total remove was achieved in all patients (100%), determined by postoperative contrast computed tomography scans and magnetic resonance imaging. There was no postoperative spinal instability. All patients had equal or better neurologic functions after surgery at follow-up. The average preoperative Nurick's grade mean was 1.9 and the postoperative was 1.1. The average preoperative McCormick's grade mean was 2.9 versus 1.3 in the postoperative period. CONCLUSIONS: Selective extradural or intradural-extramedullary tumors well localized and up to 2 levels can be safely and effectively treated by minimally invasive surgery using a full endoscopic visualization and the Caspar's retractor. However, there is insufficient evidence to recommend this approach over the classical or other microsurgical approach described.
RESUMO
Se realizó un estudio descriptivo y transversal, durante el 2013, de los 16 pacientes con el virus de la inmunodeficiencia humana/sida en el municipio II Frente, provincia de Santiago de Cuba, con vistas a caracterizarles según variables de interés para la investigación. Entre los resultados principales predominaron: el sexo masculino (87,5 %), el grupo etario de 20-29 años (50,0 %), el nivel escolar universitario (43,7 %), los desocupados, los solteros, así como la vía sexual como la forma de contagio más común. La incidencia de VIH/sida en este municipio ha ascendido en los últimos años y los consejos populares de mayor tasa resultaron ser Mayarí y Loma Blanca.
A descriptive and cross sectional study was carried out during the 2013, on the 16 patients with the human immunodeficiency virus/aids in II Frente municipality, Santiago de Cuba province, with the aim of characterizing them according to variables of interest for the investigation. Among the main results there were: the male sex (87.5%), the age group 20-29 years (50.0%), the university school level (43.7%), the unemployed, the single persons, as well as the sexual pattern as the most common way of infection. The incidence of HIV/aids in this municipality has increased in the last years and the people's councils of higher rates were Mayarí and Loma Blanca.
