Maximal Aerobic Power, Quality of Life, and Ejection Fraction in Survivors of Childhood Cancer Treated with Anthracyclines.

BACKGROUND: Anthracycline-induced cardiotoxicity is a frequent complication that can occur at any stage of treatment, even in survivors. OBJECTIVE: To determine maximum aerobic power, quality of life, and left ventricular ejection fraction in childhood cancer survivors treated with anthracyclines. DESIGN: Cross-sectional, observational study. METHODS: The left ventricular ejection fraction was obtained from the transthoracic echocardiogram report in the medical records. Each patient underwent a 6-minute walk test, assessment of maximum aerobic power on a cycle ergometer, and evaluation of perceived exertion using the EPInfant scale, and finally, their quality of life was evaluated using the pediatric quality of life inventory model. RESULTS: A total of 12 patients were studied, with an average of 16.2 years of age. All patients exhibited a left ventricular ejection fraction >60%, the mean distance covered in the 6-minute walk test was 516.7 m, and the mean of the maximum aerobic power was 70 W. Low quality of life scores were obtained in the physical and psychosocial aspects. In the Pearson test, a weak correlation without statistical significance was found between all the variables studied. CONCLUSIONS: Simultaneously with the detection of cardiotoxicity in childhood cancer survivors, it is pertinent to perform physical evaluations as physical condition and cardiotoxicity seem to be issues that are not necessarily dependent.

Reproducibility and safety of the 30" sit to stand test in individuals with obesity and cardiovascular risk factors.

BACKGROUND: The 30″ sit to stand test is a submaximal exercise test that assesses functional capacity and it has been validated for various pathologies. Although it has been used in individuals with obesity, its reproducibility in this population has not yet been determined. The main objective of this study was to determine the reproducibility and safety of the 30″ sit to stand test in individuals with overweight or obesity and with cardiovascular risk factors. METHODS: A cross-sectional study was performed. Individuals with obesity or overweight who also presented cardiovascular risk factors were evaluated with the 30″ sit to stand test. The reproducibility and safety of the 30" sit to stand test were determined, as well as its association with other functional tests and anthropometric characteristics. RESULTS: 59 individuals (27 men, 32 women) with obesity or overweight and cardiovascular risk factors, aged 57.93 (9.62) years, were included in the study. The 30″ sit to stand test showed good overall reproducibility (0.907 ICC) and significant correlation with the 6-minute walk test, handgrip strength test, body fat percentage and waist - height index, with a similar hemodynamic response to the 6-minute walk test. CONCLUSION: The 30" sit to stand test is a highly reproducible and safe test for individuals with obesity and cardiovascular risk factors, with a significant correlation to anthropometric characteristics and other functional tests regularly used for the evaluation of individuals with obesity.

Efficacy of prolotherapy in pain control and function improvement in individuals with lateral epicondylitis: A Systematic Review and Meta-analysis.

AIM: The objective of this study was to evaluate the efficacy of prolotherapy when treating individuals with lateral epicondylitis through a systematic review and meta-analysis. METHODS: The search for articles was carried out in electronic databases including PUBMED, CENTRAL, WEB OF SCIENCE, SCIELO and Google Scholar, published up to July 2021. We used the following keywords: prolotherapy OR proliferation therapy OR hypertonic dextrose injections AND tennis elbow OR lateral epicondylitis. The effectiveness was expressed as mean difference or standardized mean difference ((d) and 95% CI). MAJOR RESULTS: Nine clinical trials that used prolotherapy in the treatment of lateral epicondylitis were included. In the pooled analysis, prolotherapy was effective in pain control in the medium (d = -0.85, 95% CI -1.29 to -0.41, p (z) 0.0001) and long terms (d = -1.05, 95% CI -2.06 to -0.03, p (z) 0.04). It was also effective in improving function in the medium term (d = -1.21, 95% CI -1.64 to -0.78, p (z) 0.00001). CONCLUSIONS: Prolotherapy was effective for reducing pain in the medium and long terms, as well as for improving function in the medium term, in individuals with lateral epicondylitis. However, the risk of bias of the studies caused that the quality of evidence was moderate; more studies with a low risk of bias are necessary to corroborate the efficacy of prolotherapy in patients with lateral epicondylitis.

Retorno al deporte, integrando el proceso desde la rehabilitación convencional a la readaptación deportiva: revisión narrativa / Return to sport, integrating the process from conventional rehabilitation to sports readaptation: narrative review

Introducción: El proceso de retorno al deporte posterior a una lesión, ha sido abordado tradicionalmente en 2 etapas sepa-radas: primero el atleta es tratado por el servicio médico mediante procesos de rehabilitación convencional y posteriormentees referido al equipo deportivo (entrenador y/o preparador físico) quienes completan el regreso a la actividad deportiva. Esteabordaje puede carecer de comunicación y coordinación entre ambos equipos y tal vez es insuficiente para las demandasdel entorno deportivo actual, originando procesos más largos de retorno al deporte y mayor riesgo de re-lesión. El objetivode este manuscrito es documentar los modelos actuales de retorno al deporte, sus etapas, objetivos y contenidos.Material y método: Se realizó una revisión exhaustiva de publicaciones que incluyó estudios observacionales, ensayos clínicos,revisiones, consensos, revisiones sistemáticas y meta análisis, relacionadas con el tratamiento, rehabilitación, readaptación yretorno a la actividad deportiva.Resultados: Se encontró la descripción de un modelo de retorno a la actividad deportiva de progresión gradual que incluye 3etapas: retorno a la participación, readaptación al deporte y retorno al máximo de rendimiento deportivo. La etapa de retornoa la participación tiene como objetivo eliminar la sintomatología y recobrar la funcionalidad del atleta en sus actividades nodeportivas, mediante procesos de rehabilitación convencional. La etapa de readaptación al deporte tiene el objetivo de alcanzarla realización asintomática de las actividades de entrenamiento y competición, mediante la rehabilitación de las deficienciasoriginadas por la lesión y el mantenimiento y/o desarrollo de las capacidades motoras con entrenamiento modificado. Laetapa de retorno al máximo rendimiento deportivo incluye el entrenamiento deportivo específico para alcanzar el nivel derendimiento previo a la lesión.Conclusiones: Este modelo, podría estar asociado a...(AU)

Introduction: The process of return to sport after injury, has traditionally been approached in 2 separate stages; first theathlete is treated the medical service through conventional rehabilitation processes and is then referred to the sports team(coach and / or physical trainer) who complete the return to the sport activity. This approach may lack communication andcoordination between both teams and may be insufficient for the demands of the current sports environment, causing longerprocesses of return to sport and greater risk of re-injury. The objective of this manuscript is to document the current modelsof return to sport, its stages, objectives and contents.Material and method: A comprehensive review of publications was carried out, including observational studies, clinical trials,reviews, consensus, systematic reviews and meta-analysis, related to treatment, rehabilitation, readaptation and return to sport.Results: The description of a model of return to sports of gradual progression that includes 3 stages was found: return toparticipation, readaptation to sport and return to maximum sports performance. The stage of return to participation aimsto eliminate the symptoms and regain the functionality of the athlete in their non-sports activities, through conventionalrehabilitation processes. The stage of readaptation to sport aims to achieve asymptomatic performance of training and com-petition activities, through the rehabilitation of deficiencies caused by the injury and the maintenance and / or developmentof motor skills with modified training. The stage of return to maximum sports performance includes specific sports trainingto reach the level of performance prior to the injury.Conclusions: This model could be associated with greater success in returning to sports activity and lower risk of recurrenceof the injury.(AU)

Guía para una adecuada telerrehabilitación en personas convalecientes de Covid-19 / Guide for an adequate telerehabilitation in convalescent people of Covid-19

La pandemia de COVID-19 aún persiste y debemos mantener las medidas restrictivas. Sabemos que alrededor de 14% de los casos presentan una infección respiratoria aguda grave y que en 5% de los casos se requiere ingreso en una unidad de cuidados intensivos (UCI) con ventilación mecánica prolongada, sedación y uso de agentes bloqueantes neuromusculares; por tanto, existe un alto riesgo de desarrollar debilidad adquirida en la UCI. Por tales razones los profesionales de la rehabilitación deben considerarse trabajadores de primera línea que deben participar en la atención de los pacientes con COVID-19 grave en cuidados intensivos, hospitalización o cuando el paciente regresa al hogar y todavía está en recuperación.

The COVID-19 pandemic still persists and we must maintain restrictive measures. We know that about 14% of cases present with severe acute respiratory infection and that 5% of cases require admission to an intensive care unit (ICU) with prolonged mechanical ventilation, sedation and use of neuromuscular blocking agents; therefore, there is a high risk of developing ICU-acquired weakness. For such reasons rehabilitation professionals should be considered front-line workers who should be involved in the care of patients with severe COVID-19 in intensive care, hospitalization or when the patient returns home and is still recovering.
