RESUMO

BACKGROUND: While the association between handgrip strength and all-cause mortality is more deeply explored, no previous studies have been specifically focused on handgrip strength and respiratory disease mortality. The purpose of the study was to investigate the association between handgrip strength and respiratory disease mortality in a large representative sample. METHODS: Individuals aged 50 or over from 27 European countries and Israel participated in this longitudinal study. Data on handgrip strength and all-cause and respiratory disease mortality were retrieved from the Survey of Health, Ageing and Retirement in Europe (SHARE) waves 1, 2, 4, 5, 6 and 7. We estimated the sub hazard ratios (SHRs) for respiratory disease mortality using a Fine-Gray sub-distribution method with both time-varying exposure and covariates and mortality due to other causes as competing risk. Furthermore, we assessed dose-response associations of handgrip strength (modelled as a continuous exposure) with respiratory disease mortality using restricted cubic splines and estimated hazard ratios (HRs). RESULTS: We included 60,883 men and 74,904 women with a mean age of 63.6 (SD 9.7) years at study entry. During a median (interquartile range) of 7.4 years of follow-up 565 (0.4%) participants died due to respiratory diseases. The increase of 1 single kg of handgrip strength showed a 6% incidence reduction on respiratory disease mortality (SHR, 0.94; 95%CI, 0.92-0.96) after adjusting for potential confounders. Furthermore, each kg increase of handgrip strength reduced respiratory disease mortality risk in a dose-response fashion and a significant threshold for values of 41 kg (HR, 0.49; 95%CI, 0.26-0.92) and higher was identified. CONCLUSIONS: Higher handgrip strength is associated with lower mortality due to respiratory disease. Intervention studies are needed to determine whether strength training in respiratory disease patients can prevent premature mortality.

RESUMO

Introducción: Para evaluar el estado funcional es fundamental contar con instrumentos simples que permitan hacer un seguimiento del curso de los síntomas y del compromiso que pueden presentar las personas adultas sobrevivientes de COVID-19. Este estudio tiene como objetivo evaluar las propiedades psicométricas de la escala de estado funcional post-COVID-19 (Post COVID-19 Functional Status [PCFS]). Material y método: Corresponde a un estudio transversal de validación de escala. En la validación de contenido participaron 22 profesionales sanitarios, quienes mediante juicio de expertos evaluaron la escala en las categorías de suficiencia, claridad, coherencia y relevancia. Así también, dos profesionales realizaron la prueba de test-retest con 20 personas que habían cursado con infección por COVID-19. Adicionalmente, expusieron sus observaciones y comentarios. El grado de acuerdo entre los expertos fue determinado con el coeficiente de Kendall. Para el test-retest se utilizó el coeficiente de Spearman. En todos los análisis fue considerado significativo un valor de p<0,05. Resultados: En relación con la validez de contenido, hubo acuerdo entre evaluadores solo para la categoría relevancia (p=0,032). Se obtuvo buena fuerza de concordancia entre dos evaluadores (Rho de Spearman=0,929 para la puntuación). Se ajustaron algunos términos del contenido sin afectar la estructura general de la escala. De los 16 ítems originales que componen la escala PCFS, no se eliminó ninguno.ConclusionesLa versión en español para Chile de la PCFS, adaptada al contexto cultural del país, muestra buenas características psicométricas en términos de confiabilidad.(AU)


Introduction: To evaluate functional state, it is fundamental to have simple instruments that allow for monitoring the course of symptoms and the commitment of the functional status that adult COVID-19 survivors may present. This study aims to evaluate the psychometric properties of the Post COVID-19 Functional Status (PCFS) scale. Material and methods: A cross-sectional scale validation study was performed. In the content validation 22-health professionals, whom through expert judgment evaluated the scale in the sufficiency, clarity, coherence and relevance categories. In addition, two professionals performed the retest with 20 people who had been infected with COVID-19. In addition, their observations and comments are revealed. The degree of agreement amongst the experts was determined with the Kendall coefficient. For the retest test, the Spearman coefficient was utilized. In all the analyzes, a P value of <.05 was considered. Results: In regards to the content validity, there was agreement between raters only for the relevance category (P=.032). A strong agreement was obtained between two evaluators (Spearman's Rho=.929 for the score). Some of the content terms were adjusted without affecting the general structure of the scale. Of the original 16 items that make up the PCFS scale, none was eliminated. Conclusions: The Spanish version of the PCFS (Chile) was adapted to the cultural context of the country, shows good psychometric characteristics in terms of reliability.(AU)

RESUMO

BACKGROUND: In coronavirus disease (COVID-19), physical capacity is one of the most impaired sequelae. Due to their simplicity and low cost, field tests such as the six-minute walk test (6MWT) are widely used However, in many places it is difficult to perform them and alternatives can be used such as the 1 min sit-to-stand test (1min-STST) or the Chester step test (CST). Therefore, our objective was to compare the 6MWT, 1min-STST and the CST in post-COVID-19 patients. METHODS: We conducted a cross-sectional analysis in post-COVID-19 patients, compared with matched controls (CG). Demographic characteristics and comorbidities were collected. We analysed oxygen saturation (SpO2), heart rate (HR), and the modified Borg scale in the 6MWT, 1min-STST, and CST. Additionally, the correlations between tests were analysed. RESULTS: We recruited 27 post-COVID-19 patients and 27 matched controls. The median age was 48 (IQR 43-59) years old (44% female). The median distance walked in 6MWT was 461 (IQR 415-506) m in post-COVID-patients and 517 (IQR 461-560) m in CG (p = 0.001). In 1min-STST, the repetitions were 21.9 ± 6.7 and 28.3 ± 7.1 in the post-COVID-19 group and CG, respectively (p = 0.001). In the CST, the post-COVID-19 group performed 150 (86-204) steps vs the CG with 250 (250-250) steps (p < 0.001). We found correlations between the 6MWT with the 1min-STST in COVID-19 patients (r = 0.681, p < 0.001) and CG (r = 0.668, p < 0.001), and between the 6MWT and the CST in COVID-19 patients (r = 0.692, p < 0.001). CONCLUSION: The 1min-STST and the CST correlated significantly with the 6MWT in patients post-COVID-19 being alternatives if the 6MWT cannot be performed.

RESUMO

BACKGROUND: Evidence suggests lungs as the organ most affected by coronavirus disease 2019 (COVID-19). The literature on previous coronavirus infections reports that patients may experience persistent impairment in respiratory function after being discharged. Our objective was to determine the prevalence of restrictive pattern, obstructive pattern and altered diffusion in patients post-COVID-19 infection and to describe the different evaluations of respiratory function used with these patients. METHODS: A systematic review was conducted in five databases. Studies that used lung function testing to assess post-infection COVID-19 patients were included for review. Two independent reviewers analysed the studies, extracted the data and assessed the quality of evidence. RESULTS: Of the 1973 reports returned by the initial search, seven articles reporting on 380 patients were included in the data synthesis. In the sensitivity analysis, we found a prevalence of 0.39 (CI 0.24-0.56, p < 0.01, I2 = 86%), 0.15 (CI 0.09-0.22, p = 0.03, I2 = 59%), and 0.07 (CI 0.04-0.11, p = 0.31, I2 = 16%) for altered diffusion capacity of the lungs for carbon monoxide (DLCO), restrictive pattern and obstructive pattern, respectively. CONCLUSION: Post-infection COVID-19 patients showed impaired lung function; the most important of the pulmonary function tests affected was the diffusion capacity.

RESUMO

STUDY DESIGN: Cross-sectional. OBJECTIVE: To assess cough using air stacking (AS) to assist inspiratory volume with abdominal compression (AC) during expiration in patients with American Spinal Injury Association Impairment Scale (AIS) A. SETTING: Large tertiary hospital in Chile. METHODS: Peak cough flow (PCF) was measured during four different interventions: spontaneous maximal expiratory effort (MEE); MEE while receiving AC (MEE-AC); MEE after AS with a manual resuscitation bag (AS-MEE); and MEE with AS and AC (AS-MEE-AC). RESULTS: Fifteen in-patients with complete tetraplegia (C4-C6) were included. Median age was 33 years (16-56). PCF during the different interventions was PCF for MEE was 183±90 l min(-1); PCF for MEE-AC was 273±119 l min(-1); PCF for AS-MEE was 278±106 l min(-1) and PCF for AS-MEE-AC was 368±129 l min(-1). We observed significant differences in PCF while applying MEE-AC and AS-MEE compared with MEE (P=0.0001). However, the difference in PCF value was greater using the AS-MEE-AC technique (P=0.00001). CONCLUSION: Patients with spinal cord injury (SCI) presented an ineffective cough that constitutes a risk factor for developing respiratory complications. The application of combined techniques (AS-MEE-AC) can reach near normal PCF values. This is a low-cost, simple and easily applied intervention that could be introduced to all patients with tetraplegia.
