    Objectives: We aimed to describe the clinical, microbiological, and imaging characteristics of patients with infective endocarditis (IE) in studies from Latin America (LATAM). Methods: A systematic search through PubMed, EMBASE, LILACS, and SciELO from inception until Febru ary 2021 was conducted. We included observational studies that assessed adults with IE from LATAM and reported data on clinical, microbiological, or imaging characteristics. Data were independently extracted by 2 authors and the risk of bias was evaluated by study design with its respective tool. Findings were summarized using descriptive statistics. Results: Forty-four studies were included. Most cases were male (68.5%), had a predisposing condition including valve disease (24.3%), or had a prosthetic valve (23.4%). Clinical manifestations included fever (83.9%), malaise (63.2%), or heart murmur (57.7%). A total of 36.4% and 27.1% developed heart failure or embolism, respectively. Blood cultures were negative in 23.9% and S. aureus (18.6%) and the viridans group streptococci (17.8%) were the most common isolates. Most cases were native valve IE (67.3%) affecting mainly left-sided valves. Echocardiographic findings included vegetations (84.3%) and regurgitation (75.9%). In-hospital mortality was 25.1%. Conclusions: This is the first systematic review that evaluated the characteristics of IE in LATAM patients. A lack of multicenter studies reflects the need for these studies in LATAM

Métodos Se elaboró una encuesta virtual abierta realizada en la plataforma de encuestas de Google, dirigida a los padres con 5 preguntas: 1. Edad de su hijo: 2. ¿Cuántos minutos por día de actividad física en casa realiza? 3. ¿Cuántos minutos de pantallas (TV, computador, celular, videojuegos, etc.) por día? 4 ¿Cuántas horas duerme en la noche? 5. ¿El peso corporal de su hijo(a) se ha elevado? ¿Cuánto? Se distribuyó en las bases de datos de la Asociación de Medicina del Deporte y de la Fundación Colombiana del Corazón a través de las redes sociales como WhatsApp y correos electrónicos. Resultados Se realizaron 1.139 encuestas virtuales . Se encontró que durante el período de aislamiento obligatorio: el 75.2% de los niños no realizó los minutos recomendados de actividad física por la Organización Mundial de la salud (OMS), que el 82.8 % superó el tiempo de 60 minutos frente a dispositivos electrónicos y que el 44 % se aumentó de peso. Conclusiones En los períodos de confinamiento es importante el diseño de estrategias y procesos educativos que promuevan en los niños estilos de vida que se puedan conservar a futuro en el adulto.Introduction In Colombia from March 24 to August 31, 2020, children and adolescents spent 162 days in total mandatory preventive isolation due to the Covid-19 pandemic. Knowing and evaluating their behavior during this period of confinement was important to know the consequences on the physical activity and weight gain. Methods An open virtual survey was developed on the Google survey platform, addressed to parents with 5 questions: 1. The age of your child: 2. How many minutes of physical activity at home do you do? 3 How many minutes of screens (TV, computer, cell phone, video games, etc.) per day? 4 How many hours do you sleep at night? 5. Has your child's body weight increased? How much?. It was distributed in the databases of the Association of Sports Medicine and the Colombian Heart Foundation through social networks such as WhatsApp and emails.

    AI-based techniques have included countless applications within the engineering field. These range from the automation of important procedures in Industry and companies, to the field of Process Control. Smart Home (SH) technology is designed to help house residents improve their daily activities and therefore enrich the quality of life while preserving their privacy. An SH system is usually equipped with a collection of software interrelated with hardware components to monitor the living space by capturing the behavior of the resident and their occupations. By doing so, the system can report risks, situations, and act on behalf of the resident to their satisfaction. This research article shows the experimentation carried out with the human activity recognition dataset, CASAS Kyoto, through preprocessing and cleaning processes of the data, showing the Vía Regression classifier as an excellent option to process this type of data with an accuracy 99.7% effectiv

    Reminders are a core component of many assistive technology systems and are aimed specifically at helping people with dementia function more independently by compensating for cognitive deficits. These technologies are often utilized for prospective reminding, reminiscence, or within coaching-based systems. Traditionally, reminders have taken the form of nontechnology based aids, such as diaries, notebooks, cue cards and white boards. This article is based on the use of machine learning algorithms for the detection of Alzheimer’s disease. In the experimentation, the LWL, SimpleLogistic, Logistic, MultiLayerPercepton and HiperPipes algorithms were used. The result showed that the LWL algorithm produced the following results: Accuracy 98.81%, Precission 100%, Recall 97.62% and F- measure 98.80
