Resumen Introducción: En el confinamiento durante la pandemia por COVID-19, los sistemas de salud tuvieron que reorganizarse de manera rápida y eficiente para la atención de estos pacientes. Asimismo, la participación de los fisioterapeutas fue esencial en el tratamiento y rehabilitación pulmonar de los pacientes con COVID-19; sin embargo, existen pocos fisioterapeutas en México con especialidad en terapia respiratoria. Objetivo: Describir los sistemas corporales a los que se enfocaron las intervenciones en el manejo de pacientes con COVID-19 por parte de los fisioterapeutas mexicanos, así como sus necesidades de formación. Método: Se realizó una encuesta a fisioterapeutas con licenciatura y que laboraban en los ámbitos público y privado en el periodo de confinamiento comprendido entre junio y septiembre del 2021. Los fisioterapeutas fueron invitados a través de Facebook y la página web oficial de la Licenciatura en Fisioterapia. Para conocer la consistencia interna de la encuesta calculamos el alfa de Cronbach, la cual resultó de 0.76, basado en elementos estandarizados. La encuesta incluyó preguntas relacionadas con los sistemas corporales hacia los que enfocaron sus intervenciones y las necesidades de formación para tratar pacientes con COVID-19. Resultados: Un total de 312 fisioterapeutas participaron en la encuesta, de los cuales 112 participaron en la atención de pacientes con COVID-19, cuyas intervenciones se enfocaron principalmente al sistema musculoesquelético y cardiorrespiratorio. El domicilio del paciente y la unidad de cuidados intensivos fueron los lugares donde más frecuentemente atendieron pacientes; 76.2% de los participantes reportaron la necesidad de conocimiento especializado y más de la mitad se basó su tratamiento en las guías de práctica clínica. Conclusiones: Los fisioterapeutas mexicanos se enfocaron principalmente en los sistemas musculoesquelético y respiratorio, durante la atención de los pacientes con COVID-19, y expresaron la necesidad de tener una formación especializada en el área respiratoria.

Abstract Introduction: During the confinement during the COVID-19 pandemic, health systems had to reorganize quickly and efficiently to care for these patients. Likewise, the participation of physiotherapists was essential in the treatment and pulmonary rehabilitation of patients with COVID-19, however, there are few physiotherapists in Mexico specializing in respiratory therapy. Objective: To describe the body systems that were focused on the interventions in the management of patients with COVID-19 by Mexican physiotherapists, as well as their training needs. Method: A survey was carried out on physiotherapists with a degree and who worked in the public and private spheres in the period of confinement between June and September 2021. The physiotherapists were invited through Facebook and the official website of the bachelor in Physiotherapy. To know the internal consistency of the survey, we calculated Cronbach’s alpha, which was 0.76 based on standardized elements. The survey included questions related to the body systems they targeted and training needs to treat patients with COVID-19. Results: A total of 312 physiotherapists participated in the survey, of which 112 participated in the care of patients with COVID-19 whose interventions focused on the musculoskeletal and cardiorespiratory systems. The patient’s home and the intensive care unit were the places where patients were most frequently attended; 76.2% of the participants reported the need for specialized knowledge and more than half based their treatment on clinical practice guidelines. Conclusions: Mexican physiotherapists focus mainly on the musculoskeletal and respiratory systems during the care of patients with COVID-19 and express the need for specialized training in the respiratory area.

Resumen Introducción La pandemia de COVID-19 impactó negativamente la salud tanto física como mental a lo largo del mundo. Es importante identificar las manifestaciones psicológicas de la población y el impacto de la pandemia en los estilos de vida (actividad física, calidad del sueño). Objetivo Describir la relación entre el afecto (positivo y negativo) y la actividad física (AF) en estudiantes universitarios durante la pandemia de COVID-19. Método Se realizó una encuesta transversal a estudiantes de ciencias de la salud pertenecientes a tres instituciones de educación superior en México y Colombia. La AF se evaluó mediante la versión corta del Cuestionario Internacional de Actividad Física (IPAQ-S), y los afectos se midieron mediante el Índice PANAS. Se utilizó un modelo de regresión logística para evaluar la asociación entre AF y afectos. Resultados Se incluyeron 430 participantes entre 16 y 40 años. No encontramos diferencias entre hombres y mujeres en cuanto a edad, peso (IMC), nivel de AF ni el número de horas sentados por día, sin embargo, el consumo mensual de alcohol y tabaco fueron más frecuentes en hombres (p < .05) y las mujeres expresaron tener peor calidad de sueño (p < .05). Al ajustar por la cantidad de horas que pasaban sentados por día, el género, IMC, edad, calidad del sueño y los hábitos de consumo de tabaco y alcohol, los participantes expresaron tener más afectos positivos cuando realizaban mayor AF, sin embargo, no encontramos asociación entre AF y los afectos negativos. Discusión y conclusión Es fundamental priorizar la salud mental y las evaluaciones que determinan el impacto tardío de la pandemia de COVID-19 en el bienestar psicológico. Se considera necesario promover la AF en las comunidades universitarias para impactar positivamente en la salud mental de los estudiantes y brindar herramientas que faciliten el afrontamiento.

Abstract Introduction The COVID-19 pandemic has negatively impacted physical and mental health worldwide. It is essential to continue exploring the population’s psychological manifestations and the pandemic’s impact on lifestyles (physical activity, quality of sleep). Objective This research aimed to describe the relationship between affect (positive and negative) and physical activity (PA) in college students during the COVID-19 pandemic. Method A cross-sectional survey was conducted on health sciences students from three universities in Mexico and Colombia. PA was assessed using the short version of the International Physical Activity Questionnaire (IPAQ-S), and affects were measured using the PANAS index. A logistic regression model was used to assess the association between PA and affect. Results We included 430 participants between 16 and 40 years. We found no differences between the male and female participants regarding age, weight (BMI), PA, or the number of hours of sitting per day. The monthly consumption of alcohol and tobacco was more frequent in males (p < .05), and women expressed having worse sleep quality (p < .05). Adjusting for the number of hours spent sitting per day, gender, BMI, age, sleep quality, smoking and alcohol consumption habits, participants reported having more positive affect when they engaged in greater PA. No association was found between PA and negative affect. Discussion and conclusion Prioritizing mental health and assessments that determine the late impact of the COVID-19 pandemic on psychological well-being is critical. Promoting PA in university communities is considered a priority to positively impact students’ mental health and provide tools to facilitate coping.

Resumen Introducción: La pandemia por COVID-19 desencadenó consecuencias graves en la salud tanto física como emocional de la población en general. Objetivo: Describir los perfiles emocionales y los hábitos de actividad física, sueño, consumo de tabaco y alcohol en estudiantes de fisioterapia, en el contexto de la pandemia por COVID-19. Método: Se llevó a cabo una encuesta transversal entre julio y agosto de 2021, a través de un formulario de Google forms. Se administró la escala PANAS para evaluar el afecto positivo y negativo, el cuestionario ICSP para evaluar la calidad del sueño y el cuestionario IPAQ-S para estimar el nivel de actividad física. Resultados: Se incluyeron 60 estudiantes entre 17 y 22 años, principalmente del sexo femenino (71.7%). La mayoría de los participantes informó tener un bajo consumo de alcohol (43.3%) y tabaco (96.7%). Una mayor proporción reportó un nivel alto de actividad física (53.3%) y consideró que disminuyó después de que inició la pandemia de COVID-19 (76.7%). En cuanto a la calidad del sueño, la mayoría de los estudiantes reportaron dormir mal (66.7%). Identificamos un perfil emocional “positivo”, relacionado con afecto positivo, y tres perfiles relacionados con afecto negativo; “molesto”, “ansioso” y “culpable”. Conclusiones: Basados en la descripción de los patrones de respuesta emocional y los hábitos de actividad física, sueño y consumo de alcohol y tabaco de los participantes, se sugiere establecer programas de apoyo psicológico, haciendo énfasis en el manejo de los recursos emocionales que tienen los estudiantes para enfrentar situaciones estresantes provocadas por el confinamiento durante la pandemia del COVID-19.

Abstract Introduction: The COVID-19 pandemic triggered severe consequences for the physical and emotional health of the general population. Objective: Describe the emotional profiles and the habits of physical activity, sleep, tobacco, and alcohol consumption in physiotherapy students, in the context of the COVID-19 pandemic. Method: We conducted a cross-sectional survey of university physiotherapy students through a Google forms. We used the PANAS scale to assess positive and negative affect, the PSQI questionnaire to assess sleep quality, and the IPAQ-S questionnaire for physical activity. Results: We included 60 students between 17 and 22 years old, primarily female (71.7%). Most participants reported having a low consumption of alcohol (43.3%) and tobacco (96.7%). A higher proportion reported a high level of physical activity (53.3%) and considered it decreased after the COVID-19 pandemic (76.7%). Regarding sleep quality, most students reported poor sleep (66.7%). We identified one emotional profile “positive,” related to positive affect, and three profiles related to negative affects; “upset,” “anxious,” and “guilty.” Conclusions: Based on the description of the emotional response and the physical activity, sleep, alcohol, and tobacco consumption habits of the participants, it is suggested to establish psychological support programs, emphasizing the management of the emotional resources that the students have to face stressful situations caused by the confinement during the COVID-19 pandemic.

Abstract INTRODUCTIONSARS-CoV-2 infection can produce endothelial injury and microvascular damage, one cause of the multiorgan failure associated with COVID-19. Cerebrovascular endothelial damage increases the risk of stroke in COVID-19 patients, which makes prompt diagnosis important. Endothelial dysfunction can be evaluated by using transcranial Doppler ultrasound to study cerebral hemodynamic reserve, but there are few of these studies in patients with COVID-19, and the technique is not included in COVID-19 action and follow-up guidelines nationally or internationally. OBJECTIVEEstimate baseline cerebral hemodynamic patterns, cerebral hemodynamic reserve, and breath-holding index in recovered COVID-19 patients. METHODWe conducted an exploratory study in 51 people; 27 men and 24 women 20–78 years of age, divided into two groups. One group comprised 25 recovered COVID-19 patients, following clinical and epidemiological discharge, who suffered differing degrees of disease severity, and who had no neurological symptoms or disease at the time they were incorporated into the study. The second group comprised 26 people who had not been diagnosed with COVID-19 and who tested negative by RT-PCR at the time of study enrollment. Recovered patients were further divided into two groups: those who had been asymptomatic or had mild disease, and those who had severe or critical disease. We performed transcranial Doppler ultrasounds to obtain baseline and post-apnea tests of cerebral hemodynamic patterns to evaluate cerebral hemodynamic reserve and breath-holding indices. We characterized the recovered patient group and the control group through simple descriptive statistics (means and standard deviations). RESULTSThere were no measurable differences in baseline cerebral hemodynamics between the groups. However, cerebral hemodynamic reserve and breath-holding index were lower in those who had COVID-19 than among control participants (19.9% vs. 36.8% and 0.7 vs. 1.2 respectively). These variables were similar for patients who had asymptomatic or mild disease (19.9% vs.19.8%) and for those who had severe or critical disease (0.7 vs. 0.7). CONCLUSIONSPatients recovered from SARS-CoV-2 infection showed decreased cerebral hemodynamic reserve and breath-holding index regardless of the disease’s clinical severity or presence of neurological symptoms. These abnormalities may be associated with endothelial damage caused by COVID-19. It would be useful to include transcranial Doppler ultrasound in evaluation and follow-up protocols for patients with COVID-19.

ABSTRACT Introduction: Short periods of distant ischemia can limit myocardial damage caused by ischemia/reperfusion. Objective: To identify the effect of remote ischemic preconditioning in relation to the postoperative behavior of creatinine, glutamic transaminase, puruvic and oxalacetic levels. Method: A quasi-experimental, explanatory, comparative study with historical control was carried out in two groups of 247 patients each; all candidates for coronary artery bypass grafting. A blood-pressure cuff was placed on the right arm in the study group alternating three inflations with three deflations of five minutes at 200 mmHg. This procedure was performed prior to during and after the major ischemic episode caused by the coronary artery impingement. Results: A significant decrease in the values of creatinine, puruvic glutamic transaminase and glutamic oxalacetic transaminase was achieved. Conclusions: Remote ischemic conditioning is an important tool to take into account for renal and hepatic protection in coronary artery bypass grafting.

RESUMEN Introducción: Breves períodos de isquemia a distancia pueden limitar el daño miocárdico producido por la isquemia/reperfusión. Objetivos: Identificar el efecto del condicionamiento isquémico a distancia con fines de protección renal y hepática, relacionado al comportamiento postoperatorio de los niveles de creatinina y transaminasas glutámico-purúvica y glutámico-oxalacética en la revascularización miocárdica quirúrgica. Método: Se realizó un estudio cuasiexperimental, explicativo, comparativo con control histórico, en dos grupos de 247 pacientes cada uno, propuestos para revascularización miocárdica quirúrgica. Se colocó un torniquete en el brazo derecho, en el grupo estudio, alternando 3 insuflaciones (con una presión de 200 mmHg) con 3 desinsuflaciones, durante cinco minutos cada una. Este procedimiento se realizó previo, durante y después de la mayor isquemia inducida, provocada por el pinzamiento de la arteria coronaria. Resultados: Se logró una disminución significativa en los valores de creatinina (p<0,001), transaminasa glutámico-purúvica (p<0,001) y transaminasa glutámico-oxalacética (p<0,05). Conclusiones: El condicionamiento isquémico a distancia es una importante herramienta a tener en cuenta para la protección renal y hepática en la revascularización miocárdica quirúrgica.

Introduction: Non-medical staff members in hospitals are highly credible at population level, and are a source of opinion even though they do not have sufficient medical training. Objectives: To analyse the attitudes of non-medical professionals of Spanish and Latin American hospitals towards organ donation and identify the factors that influence these attitudes. Material and method: Through the "Proyecto Colaborativo Internacional Donante" (International Collaborative Donor Project), a stratified random sample was selected from non-medical services of eleven hospitals: 3 Spanish (n=277), 5 Mexican (n=632), 2 Cuban (n=42) and 1 Costa Rican (n=101). Results: Of the 1052 professionals surveyed, 72% (n=754) were in favour of donating an organ after death. By country, 98% of Cubans, 80% of Mexicans, 66% of Costa Ricans and 52% of Spanish were in favour (P<.001). The most influential variables were: 1) country, with results being more positive in Mexico (odds ratio [OR]=2.197), 2) believing in the possibility that they will require a transplant (OR=2.202), 3) having discussed the issue with their family (OR=3.23), 4) the positive attitude of their partner towards donation (OR=3.322), 5) not being concerned about possible mutilation of their body after donation (OR=3.378), 6) preferring options other than burial (OR=2.525), 7) accepting an autopsy (OR=2.958). Conclusions: The attitude of non-medical staff members of hospitals towards the donation of their own organs varies greatly depending on the country of the respondent. Psychosocial factors that influence these attitudes are similar to those described at the population level.

Introducción: El personal no sanitario de centros hospitalarios tiene una importante credibilidad a nivel poblacional, siendo un grupo generador de opinión sin formación sanitaria adecuada. Objetivo: Analizar la actitud hacia la donación de los órganos de los profesionales no sanitarios de hospitales españoles y latinoamericanos, y determinar los factores que condicionan dicha actitud. Material y métodos: Del Proyecto Colaborativo Internacional Donante se selecciona una muestra aleatoria y estratificada entre los servicios no sanitarios de once hospitales: 3 españoles (n = 277), 5 mexicanos (n = 632), 2 cubanos (n = 42) y 1 costarricense (n = 101). Resultados: De los 1052 profesionales encuestados, el 72 % (n = 754) está a favor de la donación de órganos tras fallecer. Por país, el 98 % de los cubanos están a favor, el 80 % de los mexicanos, el 66 % de los costarricenses y el 52 % de los españoles (p < 0,001). Las variables con más peso son: 1) país, siendo más favorable en México (odds ratio [OR] = 2,197); 2) creer en la posibilidad de necesitar un trasplante (OR = 2,202); 3) haber comentado el tema con la familia (OR = 3,23); 4) actitud favorable de la pareja hacia la donación (OR = 3,322); 5) no estar preocupado por la posible mutilación del cuerpo tras la donación (OR = 3,378); 6) preferir otras opciones distintas de la inhumación (OR = 2,525); 7) aceptar la realización de una autopsia (OR = 2,958). Conclusiones: La actitud hacia la donación de órganos propios entre el personal no sanitario de centros hospitalarios presenta variaciones importantes según el país del encuestado. Los factores psicosociales que condicionan dicha actitud son similares a los descritos a nivel poblacional.

INTRODUCTION: Continuous venovenous hemodiafiltration, generally used in patients with acute renal failure, enables elimination of humoral mediators of systemic inflammatory response and sepsis from blood. This effect should improve treatment results in patients with multiple organ dysfunction, but evidence of improved survival is insufficient. OBJECTIVES: Describe the effect of continuous venovenous hemodiaflitration on patients with multiple organ dysfunction syndrome in terms of systemic and brain hemodynamics, oxygenation, metabolism and status on ICU separation. METHODS: An observational case series was done of 18 patients (11 men and 7 women) aged 24-78 years with multiple organ dysfunction syndrome treated with continuous venovenous hemodiafiltration in the Medical-Surgical Research Center's ICU in Havana. General, systemic and brain hemodynamic, oxygenation and metabolic variables were assessed immediately before and 12 hours after starting the procedure; vital status on separation from intensive care was recorded. For analysis, patients were grouped by whether cause of multiple organ dysfunction syndrome was septic or nonseptic. Variable means before and after treatment were compared using the Wilcoxon matched pairs test. Standardized mortality ratios were calculated for both groups, with survival efficacy defined by a ratio of <0.9. RESULTS: After 12 hours continuous venovenous hemodiafitration, the septic group showed clinical improvement, with statistically significant improvement in all variables except mean arterial pressure and brain hemodynamics. Survival to discharge from ICU was 64%, with a standardized mortality ratio of 0.66. In the nonseptic group, survival was 0% and ratio was 2.13; temperature was the only variable found to improve significantly. CONCLUSIONS: Continuous venovenous hemodiafltration improved clinical parameters and survival in patients with multiple organ dysfunction of septic origin. Further studies are needed with larger numbers of patients to corroborate these results.

This is the male case aged 59 diagnosed with left hypernephroma and thrombosis of the inferior vena cava with extension to right atrium. A multidisciplinary staff performed a left radical nephrectomy, exposition of inferior vena cava using the piggyback technique, right atriotomy and inferior cavotomy for extension of thrombus and previous clamping of right renal vein and hepatic hilus. The total surgical time was of 7 hours and 30 minutes. The procedure was performed under general anesthesia and a minimal period of cardiopulmonary shunt. Standardized transoperative monitoring of vital parameters was used and also transesophageal echocardiography to detect the total removal of thrombus and its extraction, as well as the potential detached emboli. The transoperative and postoperative course was satisfactory. A review of the international medical literature on this subject was made offering conclusions.

Se presenta el caso de un hombre de 59 años con diagnóstico de hipernefroma izquierdo y trombosis de la vena cava inferior con extensión hacia la aurícula derecha. Un equipo multidisciplinario realizó una nefrectomía radical izquierda, exposición de la vena cava inferior con técnica de piggyback, atriotomía derecha y cavotomía inferior para extracción del trombo, previo pinzamiento de la vena renal derecha y el hilio hepático. El tiempo quirúrgico total fue de 7 h 30 min. El procedimiento se realizó con anestesia general y un período mínimo de derivación cardiopulmonar. Se utilizó monitorización transoperatoria estandarizada de los parámetros vitales y además ecocardiografía transesofágica para la detección de la remoción completa del trombo y su extracción, así como posibles émbolos desprendidos. La evolución transoperatoria y posoperatoria fue satisfactoria. Se realiza una revisión de la literatura médica internacional sobre el tema y se ofrecen conclusiones.
