Clinical, microbiological, and imaging characteristics of infective endocarditis in Latin America: a systematic review
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

Impact of mandatory preventive isolation on daily physical activity and weight of children in Colombia during the SARS-cov-2 pandemic
Introducción
En Colombia desde el 24 de marzo hasta el 31 de agosto de 2020 los niños y
adolescentes estuvieron 162 días en total aislamiento preventivo obligatorio por la
pandemia del Covid 19. Conocer y evaluar el comportamiento de ellos durante este
período de confinamiento fue importante para saber las consecuencias sobre la
actividad física y el aumento peso. 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. Results
1,139 virtual surveys were conducted. It was found that during the mandatory
isolation period: 75.2% of the children did not perform the minutes of physical activity
recommended by the World Health Organization (WHO), that 82.8% exceeded the
time of 60 minutes versus to electronic devices and that 44% weight gained. Conclusions
In periods of confinement, it is important to design educational strategies and
processes that promote healthy lifestyles in children that can be preserved in the
future in adults
La importancia de la evaluación de la fragilidad en el adulto mayor con enfermedad cardiovascular
La fragilidad se considera como un síndromebiológico que afecta a múltiples sistemas yórganos que conduce a la dependencia e inclusola muerte; de allí la importancia de su medición en eladulto mayor, particularmente en el sujeto con enfermedadcardiovascular. Este estudio se realizó con el objeto dedeterminar la prevalencia de la fragilidad y pre- fragilidaddel adulto mayor que acude a un programa de rehabilitacióncardiaca.Materiales y Métodos: Estudio observacional descriptivotransversal realizado en adultos mayores con enfermedadcardiovascular que asistían al programa de rehabilitacióncardiovascular. La evaluación de la fragilidad se hizomediante los cinco criterios propuestos por Fried: pérdidainvoluntaria de peso, baja energía o agotamiento, debilidadmuscular, lentitud de la marcha y baja actividad física.Los datos se estudiaron mediante el análisis de varianzade una y dos vías y se consideró significativo estadísticamenteuna p<0,05.Resultados: Se incluyeron 35 adultos mayores de 60años. Se encontró una prevalencia de fragilidad de 23% ypre-fragilidad de 54% con mayor frecuencia en mujeres,las personas frágiles y pre-frágiles se encuentran entre 60y 75 años, las mayores de 76 años son frágiles. La mayoríade los sujetos presentan entre 1 y 2 criterios siendo losde mayor prevalencia la lentitud para la marcha y la bajafuerza muscular (51,4%).Conclusión: Evaluar la fragilidad es importante en todopaciente con enfermedad cardiovascular (ECV) para detectarlay evitar dependencia.

OBJETIVO: Determinar los efectos de un protocolo de dosis moderada de ejercicio sobre factores de riesgo cardiovasculares modificables en los funcionarios administrativos de la Universidad Simón Bolívar de la ciudad de Barranquilla. MATERIALES Y METODOS: Se estudiaron 8 sujetos, de los cuales 4 eran los casos y los otros 4 los controles. Las variables estudiadas fueron índice de masa corporal, perímetro abdominal, presión arterial, colesterol total, triglicéridos y glicemia en ayunas. Durante dos meses se realizó ejercicio aeróbico de moderada intensidad, con una frecuencia de tres veces por semana, midiendo en cada una de las sesiones los signos vitales antes, durante y después de la rutina, a fin de observar las variaciones que ocurrían durante la realización del mismo. RESULTADOS: La práctica sistemática de ejercicios aeróbicos como parte del tratamiento en el grupo de los casos logró resultados positivos sobre los valores promedios del peso corporal, glicemia, colesterol, cifras de tensión arterial sistólica y diastólica. CONCLUSIONES: Los beneficios de la aplicación del programa de ejercicios se extienden tanto a la población con factores de riesgo establecidos, como aquellos individuos que se encuentren en situación de vulnerabilidad por la exposición a factores de riesgo. ABSTRACTOBJECTIVE: To determine the effects of a protocol based on a moderate dose of exercise on modifiable cardiovascular risk factors in the administrative officers of the Simón Bolívar University in Barranquilla. MATERIALS AND METHODS: Eight subjects were studied, four of whom were cases and the other four, controls. The studied variables were body mass index, abdominal perimeter, blood pressure, total cholesterol, triglycerides and fasting blood glucose. For two months the officers did aerobic exercise of moderate intensity, at a rate of three times per week, measuring vital signs before, during and after the routine in each of the sessions, in order to observe changes occurring during the performance of the routine. RESULTS: The systematic practice of aerobic exercises as part of the treatment in the group of patients achieved positive results on mean values of body weight, blood glucose, cholesterol, systolic and diastolic numbers. CONCLUSIONS: The benefits of the implementation of the exercise program extended to the population with established risk factors as well those individuals who are in a situation of vulnerability caused by exposure to risk factors
Predictive model for the identification of activities of daily living (ADL) in indoor environments using classification techniques based on Machine Learning
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
Machine learning approach applied to human activity recognition – an application to the VanKasteren dataset
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
