The objective of this work was to study the inter-rater reliability (IRR) when detecting signs associated with COVID-19 in the LUS, as well as the performance of the test in a longitudinal or transverse orientation. Thirty-three physicians with advanced experience in LUS independently evaluated ultrasound videos previously acquired using the ULTRACOV system on 20 patients with confirmed COVID-19. For each patient, 24 videos of 3 s were acquired (using 12 positions with the probe in longitudinal and transverse orientations). The physicians had no information about the patients or other previous evaluations. The score assigned to each acquisition followed the convention applied in previous studies. A substantial IRR was found in the cases of normal LUS (κ = 0.74), with only a fair IRR for the presence of individual B-lines (κ = 0.36) and for confluent B-lines occupying 50% (κ = 0.50). No statistically significant differences between the longitudinal and transverse scans were found. The IRR for LUS of COVID-19 patients may benefit from more standardized clinical protocols.This research was partially funded by CDTI (Spanish acronym: Centre for Industrial Tech- nological Development), funding number COI-20201153.

Análisis de la variabilidad y recuperación del ritmo cardíaco tras la realización de un programa multidisplinar de rehabilitación cardiaca en pacientes con infarto agudo de miocardio mediante la práctica adaptada del tenis

El objetivo de este estudio es evaluar los efectos de un programa de rehabilitación cardiaca, basado en la adaptación de una modalidad deportiva (tenis), sobre diferentes variables del ritmo cardíaco, variables analíticas y la capacidad de esfuerzo, y comprobar si los resultados de esta actividad novedosa son superponibles a los de otros programas tradicionales, caso del cicloergómetro. Se incluyen en el estudio 135 pacientes con síndrome coronario agudo de bajo riesgo, siendo divididos en tres grupos: un primer grupo realiza el programa de rehabilitación cardiaca usando el cicloergómetro como actividad física principal; un segundo grupo realiza el programa empleando como medio un entrenamiento basado en el tenis adaptado; y un tercer grupo, o grupo control, no realiza ningún tipo de programa. La duración del programa es de 3 meses. Se han producido cambios en la variabilidad del ritmo cardíaco hasta valores normales, presentando menor riesgo de volver a sufrir otro evento cardíaco los grupos que realizaban un programa de rehabilitación cardíaca, por otro lado, se produce una mejoría significativa en los dos grupos (cicloergómetro y tenis) que realizaron el programa con respecto al grupo control a nivel de los valores lipídicos, así como en la capacidad funcional valorada mediante prueba de esfuerzo. La rehabilitación cardíaca en pacientes con síndrome coronario agudo de bajo riesgo basado en un programa de tenis adaptado produce una mejoría en la variabilidad del ritmo cardíaco, el perfil lipídico y en la tolerancia al ejercicio.The aim of this study was to measure the effects of a cardiac rehabilitation program based on a modification of a form of sport (tennis), on heart rate variability variables, on various laboratory test parameters and on an exercise stress test, and to determine if the results of this novel activity are equivalent to those of traditional programs, for example use of the bycicle ergometer. The study sample consisted of 135 patients with low-risk acute coronary syndrome. They were divided into three groups, two experimental groups and one control. One of the experimental groups used the ergometric cycle as its principal physical activity whereas the other received training in a modified form of tennis lesson.By the end of the program, which lasted for 3 months, heart rate variability variables had improved until normal values to have less risk of acute miorcadial. In other way, triglycerides, cholesterol ldl, cholesterol hdl, and exercise capacity had improved

Effects of a tennis training program designed for cardiac rehabilitation of patients with low risk acute coronary syndrome

Actualmente, en la sociedad en que vivimos predomina los estilos de vida poco saludables (sedentarismo, mala alimentación, estrés,…). Los índices de las enfermedades cardiovasculares despiertan una gran inquietud ya que, en la actualidad, constituyen la primera causa de muerte en los países desarrollados debido al estilo de vida que llevamos. Teniendo en cuenta esta problemática social hemos llevado a cabo un estudio en el cual se abordan los efectos de un programa de rehabilitación cardíaca, basado en un entrenamiento mediante la práctica del tenis adaptado, sobre pacientes con síndrome coronario agudo. El objetivo fue determinar el nivel técnico alcanzado tras el programa de entrenamiento y especificar si se producían mejoras en términos de precisión entre el pre-test y el post-test. La muestra esta formada por 6 pacientes, con una edad promedio de 53.57 ± 4.68. Se utilizó como instrumento de evaluación la observación sistemática mediante la filmación y el posterior análisis de la técnica de golpeo y de la precisión alcanzada en ellos, empleando hojas de registro validadas previamente. El análisis estadístico de los resultados muestra diferencias significativas (p≤.001 y p≤.005) tanto en la técnica de golpeo como en la precisión alcanzada tras la intervención.At the moment, the society in which we live predominates slightly healthy ways of life (sedentary lifestyle, bad foods, stress…). At the moment, rates of cardiovascular diseases means a restless alarm to us due to constitutes the first reason of death in the countries developed due to the way of life that we take. Considering this social problem we have carried out a study in which there are approached the effects of a program of cardiac rehabilitation, based on training by means of the practice of the adapted tennis, on patients by acute coronary syndrome. Our objective was to determinate the technical level reached after the program of training and to specify if improvements were taking produced in precision ends between the pre-test and the post-test. The sample is composed of a group of sixth patients, with an average age of 53.57 ± 4.68. The systematic observation was in use as instrument of evaluation by means of the filming and the later analysis of the skill of I throb and of the precision reached in them, using sheets of record validated before. The statistical analysis of the results shows significant differences (p =.001 and p =.005) so much in the skill of I throb like in the precision reached after the intervention.Sin financiaciónNo data 201

Modification of the Forms of Self-Determined Regulation and Quality of Life after a Cardiac Rehabilitation Programme: Tennis-Based vs. Bicycle Ergometer-Based

Background: The objective is to analyse and compare the effects of an adapted tennis cardiac rehabilitation programme and a classical bicycle ergometer-based programme on the type of motivation towards sports practice and quality of life in patients classified as low risk after suffering acute coronary syndrome. Methods: The Behavioural Regulation in Exercise Questionnaire (BREQ-2) and Velasco’s Qualityof Life Test were applied. The sample comprised 110 individuals (age = 55.05 ± 9.27) divided into two experimental groups (tennis and bicycle ergometer) and a control group. Results: The intra-group analysis showed a significant increase between pre- and post-test results in intrinsic regulation in the tennis group and in the control group. In identified regulation, the bicycle ergometer group presented significant differences from the control group. On the other hand, in the external regulation variable, only the tennis group showed significant differences, which decreased. Significant improvements in all quality-of-life factors when comparing the pre-test period with the post-test period were only found in the experimental groups. As per the inter-group analysis, significant differences were observed in favour of the tennis group with respect to the control group in the variables of health, social relations and leisure, and work time as well as in favour of the bicycle ergometer group compared with the control group in the variables of health, sleep and rest, future projects and mobility. No significant differences were found in any of the variables between the tennis group and the bicycle ergometer group. Conclusion: It is relevant to enhance the practice of physical exercise in infarcted patients classified as low risk as it improves the forms of more self-determined regulation towards sporting practice and their quality of life
