AIMS: We aimed to investigate the effectiveness of a telerehabilitation exercise program performed without requiring any special equipment on the physical condition of COVID-19 subjects. SETTINGS AND DESIGN: This was a randomized controlled study. METHODS: This study included subjects with a history of hospitalization with a diagnosis of COVID-19 and discharged within 4 weeks. The subjects were divided into two groups randomly, namely telerehabilitation group (TeleGr, n = 17) or control group (CGr, n = 17). The TeleGr received breathing and range of motion exercises, active cycle of breathing technique, and an aerobic training 3 days a week for 6 weeks, while CGr received an exercise brochure with the same content. Subjects were evaluated using the modified Medical Research Council (mMRC) dyspnea score for dyspnea, 30 s sit-to-stand test (30STS) and short physical performance battery (SPPB) to determine their physical status, Saint George Respiratory Questionnaire (SGRQ) to assess quality of their life, and Beck Depression Inventory. All evaluations were carried out at home using videoconferencing. RESULTS: A significant improvement was observed in TelerGr in terms of mMRC (P= 0.035), 30STS (P= 0.005), 5 sit-to-stand time which is one of the subtests of SPPB ( P = 0.039) and SGRQ scores. Significant improvement was observed only in the pain score in the CGr ( P = 0.039). There was a statistically significant difference between the groups in SGRQ activity ( P = 0.035) and total ( P = 0.042) scores. In addition, more symptomatic improvement was found in TeleGr. CONCLUSION: Telerehabilitation exercise program with less technical equipment is a good alternative treatment method for COVID-19 subjects, which improves the quality of life and symptomatic status of subjects.

BACKGROUND: Patients with COPD face an increased risk of cardiovascular disease and increased cardiac mortality. Carotid femoral pulse wave velocity (cf-PWV) is a validated measure of arterial stiffness, a well recognized predictor of adverse cardiovascular outcomes, and offers higher predictive value than classical cardiovascular risk factors. We investigated the association between COPD and arterial stiffness using cf-PWV as a noninvasive technique. METHODS: This clinical study was prospective, observational, and cross-sectional. Sixty-two subjects with stable COPD and 22 healthy controls underwent physical examination, chest x-rays, pulmonary function tests, arterial blood gas analysis, and 6-min walk test, and cf-PWV was measured via a validated tonometry system. RESULTS: The COPD subjects had greater arterial stiffness than the control subjects, and that difference was associated with lower FEV 1 , P aO 2 , and oxygen saturation during the 6-min walk test. We observed higher cf-PWV in the COPD subjects with severe COPD than in the subjects with mild to moderate COPD. Only FEV 1 was an independent predictor of cf-PWV. CONCLUSIONS: Our results suggest that arterial stiffness is increased in subjects with more severe and advanced COPD than in those with mild to moderate COPD. Air flow limitation and hypoxemia may induce increased arterial stiffness in COPD patients.
BackgroundChronic obstructive pulmonary disease (COPD) is a chronic inflammatory condition, and progresses with acute exacerbations. (AE). During AE, levels of acute phase reactants such as C-reactive protein (CRP) and inflammatory cells in the circulation increase. Soluble urokinase-type plasminogen activator receptor (suPAR) levels increase in acute viral and bacterial infections and in diseases involving chronic inflammation. The purpose of this study was to investigate the effectiveness of suPAR in predicting diagnosis of AE of COPD (AE-COPD) and response to treatment.MethodsThe study population consisted of 43 patients diagnosed with AE-COPD and 30 healthy controls. suPAR, CRP, and fibrinogen levels were measured on the first day of hospitalization and on the seventh day of treatment.ResultsWe found that fibrinogen (P<0.001), CRP (P<0.001), and suPAR (P<0.001) were significantly higher in patients with AE-COPD than in healthy controls. Fibrinogen (P<0.001), CRP (P=0.001), and suPAR (P<0.001) were significantly decreased by the seventh day of treatment. However, the area under receiver operator characteristic curve showed that suPAR is superior to CRP and fibrinogen in distinguishing AE-COPD. There was a correlation between fibrinogen, CRP, and suPAR. However, only fibrinogen was a powerful predictor of suPAR in multiple linear regression. In multiple logistic regression, only suPAR and fibrinogen were strong predictors of AE-COPD (P=0.002 and P=0.014, respectively). Serum suPAR was negatively correlated with forced expiratory volume in 1 second (r=−478, P=0.001).ConclusionsuPAR is a marker of acute inflammation. It is well correlated with such inflammation markers as CRP and fibrinogen. suPAR can be used as a predictor of AE-COPD and in monitoring response to treatment.
