Early Tracheostomy May Reduce the Length of Hospital Stay.

Introduction: There is evidence that prolonged invasive mechanical ventilation has negative consequences for critically ill patients and that performing tracheostomy (TQT) could help to reduce these consequences. The ideal period for performing TQT is still not clear in the literature since few studies have compared clinical aspects between patients undergoing early or late TQT. Objective: To compare the mortality rate, length of stay in the intensive care unit, length of hospital stay, and number of days free of mechanical ventilation in patients undergoing TQT before or after ten days of orotracheal intubation. Methods: A retrospective cohort study carried out by collecting data from patients admitted to an intensive care unit between January 2008 and December 2017. Patients who underwent TQT were divided into an early TQT group (i.e., time to TQT ≤ 10 days) or late TQT (i.e., time to TQT > 10 days) and the clinical outcomes of the two groups were compared. Results: Patients in the early TQT group had a shorter ICU stay than the late TQT group (19 ± 16 vs. 32 ± 22 days, p < 0.001), a shorter stay in the hospital (42 ± 32 vs. 52 ± 50 days, p < 0.001), a shorter duration of mechanical ventilation (17 ± 14 vs. 30 ± 18 days, p < 0.001), and a higher proportion of survivors in the ICU outcome (57% vs. 46%, p < 0.001). Conclusion: Tracheostomy performed within 10 days of mechanical ventilation provides several benefits to the patient and should be considered by the multidisciplinary team as a part of their clinical practice.

Combining functional exercises with exercise training in COPD: a randomized controlled trial.

INTRODUCTION: Increasing physical activity in daily life (PADL) in chronic obstructive pulmonary disease (COPD), mainly in short-term training programs, is still a challenge. The combination of functional exercises with aerobic and resistance training may be a strategy to improve PADL and limitations in activities of daily living (ADL) in COPD. OBJECTIVE: To evaluated the short- and medium-term effects of the combination of functional exercises with aerobic and resistance training. METHODS: Seventy-six patients were randomized into (1) functional training group who performed resistance and aerobic and functional exercises; (2) conventional training group (CTG) who performed resistance and aerobic exercise; or (3) usual care group who performed respiratory physiotherapy. Patients were evaluated for PADL (activity monitor), ADL limitations (London Chest Activity of Daily Living scale [LCADL]), functional exercise capacity (6-minute walk test [6MWT]), and peripheral muscle strength before and after eight weeks. Medium-term effects were evaluated 12 weeks after the training. RESULTS: There were no changes or differences between groups in PADL and in 6MWT post-intervention and 12 weeks post-training. Only CTG showed a reduction in the total score on LCADL scale after the intervention and increase at follow-up (score: 20 ± 8; 17 ± 6; 19 ± 8, pre-intervention, post-intervention, and 12 weeks post-training, respectively, p = 0.001), without differences between groups (p = 0.375). There were increases in the muscle strength of knee flexors (p = 0.016) and extensors (p < 0.001) after the intervention only in CTG. CONCLUSIONS: Combined aerobic and resistance training with functional exercises failed to improve PADL and ADL limitations in COPD. Eight weeks of conventional training improved ADL. This, however, was not superior to the results from the other groups and was not sustained at medium-term 12 weeks post-training.

Resistance training using different elastic components offers similar gains on muscle strength to weight machine equipment in Individuals with COPD: A randomized controlled trial.

Purpose: To compare the effects of three modalities of resistance training, two using elastic components and one using conventional weight machine on peripheral muscle strength in Individuals with chronic obstructive pulmonary disease (COPD). Effects on exercise capacity, impact of disease on health status, body composition and daily level of physical activity were investigated as secondary endpoints.Methods: Forty-eight participants were randomly allocated (Trials Registry #RBR-6V9SJJ) into Elastic band group (Theraband®) (EBG), Elastic tubes training using Lemgruber® (ETG), and Conventional training with weight machine equipment (CG). Participants were evaluated before and after 12 weeks of training regarding peripheral muscle strength by dynamometry; impact of disease on health status via COPD Assessment Test, CAT; exercise capacity by 6-min walk test, 6MWT; body composition by bioelectrical impedance; and daily level of physical activities via accelerometry.Results: Inter-group comparison of training effects did not elucidate significant differences between the modalities in muscle strength (p ≥ .2). Likewise, all training modalities showed similar effects on CAT, body composition and daily physical activity variables with no statistical significance observed (p ≥ .15).Conclusions: Modalities of resistance training using elastic components presented similar effects on muscle strength, health status, exercise capacity, body composition and daily level of physical activity in individuals with COPD. The effects of elastic resistance were similar to conventional resistance training.

Impaired performance of women with patellofemoral pain during functional tests.

OBJECTIVE: To compare the performance, reliability, and validity of functional tests between women with and without patellofemoral pain. METHODS: Twenty women with a diagnosis of patellofemoral pain between 18 and 40 years of age and 20 age-matched pain-free controls participated in the study. All participants performed a set of five function tests: sitting-rising test, sit-to-stand in 30 seconds, stair-climb test, stair descent test, and six-minute step test. To investigate reliability, participants were assessed on two different days, seven days apart, by two independent investigators blinded to the results of the other investigator. Validity was evaluated through associations with the results on the Anterior Knee Pain Scale. RESULTS: Performance in the tests was worse in women with patellofemoral pain than in the control group for the sit-to-stand in 30 seconds (mean difference [MD] 3.4reps; 95%CI: 0.4, 6.4), stair-climb test (MD: 0.36s; 95%CI: 0.1, 0.63), and six-minute step test (MD: 45reps; 95%CI: 20, 70). No differences were observed for the sitting-rising and stair descent tests. All tests in both groups showed moderate to excellent intra- and inter-rater reliability (intraclass correlation coefficients: 0.61 to 0.91 and 0.72 to 0.96, respectively). Finally, only the results on the sit-to-stand in 30 seconds test correlated with the Anterior Knee Pain Scale (r=0.44, p=0.047) in the patellofemoral pain group. CONCLUSION: Women with patellofemoral pain present lower performance on some functional tests. Functional tests are reliable in patients with patellofemoral pain, although they are not associated with the results on the Anterior Knee Pain Scale self-questionnaire.

The influence of comorbidities on outcomes of pulmonary rehabilitation programs in patients with COPD: a systematic review.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is associated with comorbidities such as cardiovascular disease, metabolic disease, osteoporosis, and anxiety and/or depression. Although pulmonary rehabilitation programs are proven to be beneficial in patients with COPD, it is unclear whether comorbidities influence pulmonary rehabilitation outcomes. The aim of the present review was to investigate to what extent the presence of comorbidities can affect pulmonary rehabilitation outcomes. METHODS: The systematic literature search (Pubmed, EMBASE, and PEDro) resulted in 4 articles meeting the inclusion criteria. The odds ratios (95% confidence intervals) of the logistic regression analyses, with comorbidities as independent variables and pulmonary rehabilitation outcomes (dyspnea, functional exercise capacity, and quality of life) as dependent variables, were used for data extraction. RESULTS: Patients with anxiety and/or depression less likely improve in dyspnea. Osteoporosis is associated with less improvements in functional exercise capacity, while cardiovascular disease does not seem to negatively impact on this outcome. Patients with cardiovascular comorbidity will experience less positive changes in quality of life. CONCLUSION: Evidence from literature suggests that comorbidities can have a negative influence on pulmonary rehabilitation outcomes. Screening for comorbidities in pulmonary rehabilitation settings seems useful to readdress the right patients for individually tailored pulmonary rehabilitation.
