Effect of early pulmonary rehabilitation therapy on the pulmonary function of patients with stroke-associated pneumonia and analysis of its effectiveness.

This study aimed to evaluate the clinical effectiveness of early pulmonary rehabilitation (PR) treatment methods for stroke-associated pneumonia (SAP). This is a prospective, randomized controlled intervention study. Eighty SAP patients admitted to the rehabilitation department of Liuzhou People's Hospital from June 2020 to December 2021 were selected and divided into an intervention group (40 cases) and a control group (40 cases) using the random number table approach. Patients in both groups received conventional treatments. Patients in the intervention group received early PR interventions, while patients in the control group received conventional rehabilitation treatment. The clinical effectiveness and pulmonary function indexes were compared. The intervention group showed shorter durations of stay in the intensive care unit, relief from symptoms, and mechanical ventilation compared to the control group following treatment (P < 0.05). The total clinical efficacy after intervention in the treatment group was 82.50%, significantly higher than the control group's rate of 47.50% (P < 0.05). After 21 days of treatment, the forced expiratory volume in one second (FEV1)/predicted value in the intervention group was 64.92 ± 8.53, while it was 52.69 ± 7.08 in the other group. The FEV1/forced vital capacity in the intervention group was 59.73 ± 7.18, compared to 50.36 ± 6.54 in the control group. The intervention group had a clinical pulmonary infection score of 2.62 ± 1.13, while the control group had a score of 4.17 ± 2.08. The intervention group showed a significant improvement in lung function, with statistically significant differences compared to the other group (P < 0.05). Moreover, the intervention group had significantly lower levels of interleukin-4 and interleukin-10 compared to the control group, with statistical significance (P < 0.05). The average National Institute of Health Stroke Scale score of the intervention group was significantly lower than that of the control group in the second and third weeks after treatment (P < 0.05). Early comprehensive pulmonary rehabilitation can significantly enhance the pulmonary function and respiratory status of SAP patients and facilitate the early recovery of brain function. This approach archives significantly better outcomes compared to conventional PR; therefore, it is worth clinical implementation.

The Impact of Early Pulmonary Rehabilitation on Dyspnea, Quality of Life, and Symptoms in Moderate to Severe COVID-19 Pneumonia Patients

Introduction: COVID-19 pneumonia leads to dyspnea, persistent symptoms and poor quality of life. Inpatient pulmonary rehabilitation (PR) has limited evidence of effectiveness. Therefore, we aimed to determine the effect of a comprehensive inpatient PR program on dyspnea symptoms and quality of life in patients with COVID-19 pneumonia. Methods: A group pretest-posttest design was conducted in patients with COVID-19 pneumonia. Comprehensive PR was administered during hospitalization. Baseline dyspnea index (BDI), Transitional dyspnea score (TDI), Modified Medical Research Council score (mMRC), and St. George’s Respiratory Questionnaire (SGRQ) were assessed at baseline, 4th week and 12th week after discharge. Results: In total, 28 patients were included (9 with oxygen supplementation, 19 without oxygen supplementation). The mean BDI at baseline was 7.82 ± 2.13. TDI scores at the 4th and 12th weeks were 5.14 ± 1.90 and 6.61 ± 1.59, respectively, with a significant difference observed between the 4th and 12th weeks (p &lt; 0.001). Median mMRC scores at baseline, 4th week, and 12th week were 2(1.25 - 3), 1 (1 - 2) and 1 (0 - 1), respectively, showing a significant improvement between baseline vs 4th week, baseline vs 12th week, and 4th week vs 12th week (p &lt; 0.001). The total SGRQ score exhibited a median (IQR) of 11.34 (7.88 - 8.58) at the 4th week and 6.93 (4.43 - 13.03) at the 12th week, demonstrating a statistically significant improvement (p &lt; 0.001). No adverse events were reported during inpatient PR. Conclusion: Inpatient PR provides a safe and feasible profile, reduces dyspnea symptoms, and improves the quality of life in patients with moderate to severe COVID-19 pneumonia. HIGHLIGHTS COVID-19 pneumonia results in dyspnea and persistent symptoms, impacting quality of life. Early pulmonary rehabilitation, from inpatient to a 12-week outpatient program for moderate and severe cases, is safe and improves dyspnea, quality of life, and patient reported symptoms.

Effect of early pulmonary rehabilitation training on the prognosis of patients with acute respiratory distress syndrome after weaning of invasive mechanical ventilation in the intensive care unit

To investigate the effect of early pulmonary rehabilitation (PR) training on the improvement of respiratory function in patients with acute respiratory distress syndrome (ARDS) after weaning of invasive mechanical ventilation in the intensive care unit (ICU). The retrospective cohort research method was used. The clinical information of adult patients with ARDS receiving invasive mechanical ventilation admitted to the ICU of Qingdao Municipal Hospital from January 2019 to March 2023 was collected. The patients were divided into a control group and an observation group according to off-line training program. The control group received traditional training after weaning, and the observation group received the early PR training after weaning. Other treatments and nursing were implemented according to the routine of the ICU. The scores of the short physical performance battery (SPPB) on day 3-day 6 of the weaning training, respiratory muscle strength, level of interleukin-6 (IL-6), number of aspirations of sputum after weaning, length of stay after weaning, rehospitalization rate within 6 months after discharge, and pulmonary function indicators at discharge and 3 months after discharge [peak expiratory flow (PEF), forced expiratory volume in one second/forced vital capacity ratio (FEV1/FVC), and vital capacity (VC)] of the two groups of patients were compared. The Kaplan-Meier survival curve was drawn to analyze the cumulative survival rate of patients 6 months after discharge. A total of 50 of which 25 cases received the traditional training after weaning, 25 cases received the early PR training after weaning. There was no significant difference in gender, age, acute physiology and chronic health evaluation II (APACHE II), oxygenation index upon admission, etiological diagnosis of ARDS upon admission, time of invasive ventilation, mode of invasive mechanical ventilation, pulmonary function indicators at discharge, and other baseline data of the two groups. The SPPB questionnaire scores and respiratory muscle strength in both groups were increased gradually with the extended offline training time, the serum level of IL-6 in both groups were descend gradually with the extended offline training time, especially in the observation group [SPPB questionnaire score in the observation group were 7.81±0.33, 8.72±0.53, 9.44±0.31, 10.57±0.50, while in the control group were 7.74±0.68, 8.73±0.37, 8.72±0.40, 9.33±0.26, effect of time: F = 192.532, P = 0.000, effect of intervention: F = 88.561, P = 0.000, interaction effect between intervention and time: F = 24.724, P = 0.000; respiratory muscle strength (mmHg, 1 mmHg≈0.133 kPa) in the observation group were 123.20±24.84, 137.00±26.47, 149.00±24.70, 155.40±29.37, while in the control group were 129.00±20.34, 126.00±24.01, 132.20±25.15, 138.60±36.67, effect of time: F = 5.926, P = 0.001, effect of intervention: F = 5.248, P = 0.031, interaction effect between intervention and time: F = 3.033, P = 0.043; serum level of IL-6 in the observation group were 80.05±6.81, 74.76±9.33, 63.66±10.19, 56.95±4.72, while in the control group were 80.18±7.21, 77.23±9.78, 71.79±10.40, 66.51±6.49, effect of time: F = 53.485, P = 0.000, effect of intervention: F = 22.942, P = 0.000, interaction effect between intervention and time: F = 3.266, P = 0.026]. Compared with the control group, the number of aspirations of sputum after weaning of patients in the observation group significantly decreased (number: 22.46±1.76 vs. 27.31±0.90), the length of ICU stay after weaning significantly became shorter (days: 6.93±0.95 vs. 8.52±2.21), and the rehospitalization rate within 6 months after discharge significantly decreased [20.00% (5/25) vs. 48.00% (12/25)]. There were significant differences. The pulmonary function indicators 3 months after discharge of two groups of patients significantly increased compared with those at discharge and those of the observation group were significantly higher than those of the control group [PEF (L/min): 430.20±95.18 vs. 370.00±108.44, FEV1/FVC ratio: 0.88±0.04 vs. 0.82±0.05, VC (L): 3.22±0.72 vs. 2.74±0.37, all P < 0.05]. The Kaplan-Meier survival curve showed that the cumulative survival rate of patients 6 months after discharge of patients in the observation group was significantly higher than that of patients in the control group [76.9% vs. 45.5%, hazard ratio (HR) = 0.344, P = 0.017]. Early PR training can significantly improve the respiratory function of patients with ARDS after weaning of invasive mechanical ventilation. Continuous active respiratory training after discharge can improve the respiratory function of patients and effectively decrease mortality.

Does Telerehabilitation for Coronavirus Disease 2019 Patients Discharged with Oxygen Shorten the Time of Weaning from Oxygen?

Early pulmonary rehabilitation (PR) and acute and post-acute mobilization with telemonitoring and telerehabilitation (TR) have been recommended for coronavirus disease 2019 (COVID-19) patients. We aimed to compare the duration of weaning from oxygen in patients with hypoxemic COVID-19 who received PR and those who did not. This study was designed as a quasi-experimental study and was conducted on patients discharged with oxygen supplementation between December 2021 and May 2022. They were compared with patients who received PR and those who did not in terms of the duration of oxygen use. A total of 61 patients (9 women in each group) completed the study. The mean age was 65 ± 12. Thirty patients underwent PR (group 1) and the remaining 31 patients were classified as control group (group 2). When the groups were compared in terms of duration of oxygen use, patients who performed PR were statistically significant shorter duration than those who did not (P = .012). In addition, PR improved their quality of life compared to group 2. It was concluded that although PR has many indications, it is also effective, feasible, and safe in prolonged infections and it was thought that TR may also be effective as supervised PR.

High flow nasal oxygen versus usual care in improving pulmonary rehabilitation outcomes of chronic obstructive pulmonary disease patients after an exacerbation - a pilot randomized controlled trial

Introduction Early pulmonary rehabilitation (PR) is guideline-recommended for all chronic obstructive pulmonary disease (COPD) patients post-hospitalization for COPD exacerbation but many patients experience difficulties participating in early PR due to significant breathlessness. High flow nasal oxygen (HFO) has been shown to improve ventilatory efficiency in stable COPD patients, but there is little data on HFO use during exercise training in PR post-COPD exacerbation. Methods We conducted a pilot randomized controlled trial (RCT) to explore the feasibility of a prospective large-scale RCT to evaluate the impact of HFO in improving PR outcomes of COPD patients post-exacerbation. Patients recently hospitalized for COPD exacerbation were enrolled and randomized to either HFO or usual care during an early 6-weeks, outpatient PR program. Results Twenty two patients were randomized between May 2019 to Dec 2019 and 18 patients completed the study. The HFO arm achieved a greater improvement in exercise capacity than the usual care arm, with the mean difference in 6-min walk distance (6MWD) being 30 m (95% CI: −23 m to 84 m), although this was not statistically significant. All 18 patients in both arms were compliant to the pulmonary rehabilitation program (defined by attending ≥75% of exercise sessions). HFO was well tolerated with no adverse events reported. Conclusion This pilot RCT has shown preliminary evidence of the feasibility and high patient acceptability of HFO during early PR on improving exercise capacity in COPD patients post-exacerbation These promising results would justify a larger RCT to confirm HFO’s benefits and has the potential to change PR practice.

An Observational Study of Respiratory Dysfunction in Parkinson’s Disease at a Tertiary Care Hospital in Delhi

Abstract Objectives: The purpose of this study is to evaluate the impact of Parkinson’s disease (PD) on respiratory function using spirometry. In addition, the study aims to investigate the relationship between the severity of PD and any impairments in a respiratory capacity as measured by forced vital capacity (FVC%). Methods: This case–control study (40 cases of PD vs. 40 healthy controls) was conducted from July 1, 2021, to October 31, 2022, in a tertiary care hospital of New Delhi. Clinical symptoms and severity (Movement Disorder Society Unified Parkinson’s Disease Rating Scale [MDS-UPDRS] part-III score and Modified H and Y Scale) of the patients of PD were noted. A pulmonary function test (by spirometry) was performed and parameters such as forced expiratory volume in 1 s (FEV1), FVC, FEV1/FVC, and peak expiratory flow rate (PEFR) were noted. Mann–Whitney U-test (for two groups) and Chi-square test were used for the comparison of variables. Spearman rank correlation coefficient was used for the correlation of FVC (% predicted) with MDS-UPDRS part-III score and Modified H and Y stage. Results: Compared to controls, cases had significantly lower FVC% (70.5 vs. 88, P &lt; 0.01), significantly lower FEV1% (68 vs. 83.5, P &lt; 0.01), comparable FEV1/FVC (% predicted) (97 vs. 96, P = 0.805) and significantly lower PEFR (% predicted) (80.5 vs. 92, P &lt; 0.01). The pattern of lung involvement was restrictive, normal, and obstructive in 72.50%, 20%, and 7.50% of cases, respectively. FVC (% predicted) showed a significant negative correlation with MDS-UPDRS part-III score (r = −0.895, P &lt; 0.01) and with Modified H and Y Scale (r = −0.792, P &lt; 0.01). Conclusion: Patients with PD had significantly more deranged respiratory dysfunction and there was significantly higher respiratory dysfunction with increasing severity of PD. A proper screening of lung functions may allow an early detection of respiratory dysfunction, thereby helping to initiate an early pulmonary rehabilitation to prevent respiratory complications.

Effects of Early Pulmonary Rehabilitation on Hospitalized Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis.

Pulmonary rehabilitation (PR) effectively improves symptoms and exercise ability in patients with stable chronic obstructive pulmonary disease (COPD). However, the effectiveness and timing of early PR on hospitalized patients with acute exacerbation of COPD (AECOPD) is still debated. This study conducted a meta-analysis to compare the outcome benefits between early PR and usual care for patient hospitalized due to AECOPD. A systematic search was performed for retrieving randomized control trials (RCTs) from the PubMed, Embase, and Cochrane library until November 2021. RCTs reporting early PR for AECOPD with hospitalization, either during admission or within four weeks of discharge, were enrolled for systematic review and meta-analysis. Twenty RCTs (1274 participants) were included. Early PR showed significantly improved readmission rate (ten trials, risk ratio 0.68, 95% confidence interval (CI) 0.50-0.92), 6-minute walking distance (6MWD, twelve trials, MD 59.73, 95% CI 36.34-83.12), St George's Respiratory Questionnaire score (eight trials, MD -10.65, 95% CI -14.78 to -6.52), Borg score (eight trials, MD -0.79, 95% CI -1.26 to -0.32), and modified Medical Research Council dyspnea scale (eight trials, MD -0.38, 95% CI -0.5 to -0.25). However, the trend of mortality (six trials, risk ratio 0.72, 95% CI 0.39-1.34) benefit was not significant. The subgroup analysis showed non-significant trends of better effect in early PR during admission than those after discharge for outcomes of 6MWD, quality of life, and dyspnea. However, non-significant trends of less benefits on mortality and readmission rate were found in early PR during the admission. Overall, early PR is beneficial for AECOPD with hospitalization, and there was no significant outcome difference between PR initiated during admission or within 4 weeks of discharge.

Early pulmonary and physical rehabilitation in cooperative patients in the respiratory ICU

Early pulmonary and physical rehabilitation in cooperative patients in the respiratory ICU

Early pulmonary rehabilitation of COVID-19 patients in an isolation ward and intensive care unit.

When patient with coronavirus disease 2019 (COVID-19) are hospitalized, the limited space for activity, disease itself causes fever, muscle aches, fatigue, respiratory failure with mechanical ventilation, or medications such as steroids or neuromuscular blocking can cause muscle dysfunction. Pulmonary rehabilitation (PR) should be arranged for these patients with COVID-19. However, the literature on early PR within 1 week of admission on patients with COVID-19 are limited. This review focuses on early PR in COVID-19 patients admitted to isolation wards or intensive care units. The essential components of early PR programs include education, breathing exercise, airway clearance, and physical activity training. Breathing exercises, including diaphragmatic and pursed-lip breathing, are known to improve lung function in chronic obstructive pulmonary disease and are also recommended for COVID-19 patients. Poor airway clearance can further aggravate pneumonia. Airway clearance techniques help patients to clear sputum and prevent the aggravation of pneumonia. Early physical activity training allows patients to maintain limb muscle function during hospitalization. It is recommended to design appropriate indoor exercise training for patients with frequency 1-2 times a day, and intensity should not be too high (dyspnea Borg Scale ≤3) in the acute stage. In order to achieve safe training, criteria for selecting stable patients and training termination are important. Early PR may help reduce the length of hospital stay, maintain functional status, improve symptoms of dyspnea, relieve anxiety, and maintain health-related quality of life in these patients after discharge.

Evaluation of respiratory Failure in Patients with Chronic Obstructive Pulmonary disease

Objectives: - The aim of the present study is to evaluate the clinical profile, investigations, treatment protocol and the response to the therapy in patient of COPD presenting with Respiratory failure.&#x0D; Materials and Methods: - All those patient with COPD with respiratory failure admitted in IPD in department of Respiratory Medicine R. D. Gardi Medical College Ujjain included in the study. Patients were evaluated by a detailed history, clinical examination, chest radiograph, arterial blood gas analysis and relevant blood investigation and were put on treatment. All the information was written in a proforma and the results were analysed.&#x0D; Results: - Majority of the patients were males (83.3%) with mean age of 65 years. In our study, the most common risk factor for COPD with respiratory failure was found to be smoking (80%). Nearly 70% cases were having type 2 respiratory failure. The main causes of exacerbations were bronchospasm(88.3%) and secondary infection (68.4%). 65% of the patients were discharged on room air with medical treatment, 23.3% patients were discharge on home oxygen with medical treatment, 3.33% patients discharged on NIV along with medical treatment and 5 patients died during hospitalization.&#x0D; Conclusion: - It is very important to take holistic approach toward COPD patient with respiratory failure. Early diagnosis, prompt treatment, pulmonary rehabilitation and vaccination are mainstay of management modalities and to prevent further exacerbation in patients.&#x0D;

Early Pulmonary Rehabilitation in Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Meta-Analysis of Randomized Controlled Trials

ABSTRACT Pulmonary rehabilitation (PR) is an essential method for Acute exacerbation in chronic obstructive pulmonary disease (AECOPD) recovery. We perform a meta-analysis to compare early PR with usual care. A literature search was performed through these databases: PubMed, MEDLINE database, Google Scholar, Cochrane, Embase from inception to July 2021. Eligible trials were clinical randomized controlled trials comparing the effects of early PR and usual care in AECOPD patients. The primary endpoint of this meta-analysis was FEV1% predicted, 6-min walk test (6MWD), modified Medical Research Council (mMRC) and George Respiratory Questionnaire-total (SGRQ-total). The secondary outcomes were borg dyspnea score, short-form 36 health survey questionnaire physical (SF-36 physical) and SF-36 mental. We included 13 RCTs with a total of 866 patients. There were no significant effects of the PR group on measures of FEV1% predicted (MD = 0.50, 95%CI −1.43 to 2.44, Z = 0.51, p = 0.61), borg dyspnea score (MD = −0.88, 95%CI −1.89 to 0.13, Z = 1.71, p = 0.09) and SF-36 mental (MD = 4.34, 95%CI −1.64 to 10.32, Z = 1.42, p = 0.16) compared with usual care. PR group achieved better 6MWD (MD = 97.58, 95%CI 17.21 to 177.96, Z = 2.38, p = 0.02), mMRC (MD = −0.36, 95%CI −0.52 to −0.21, Z = 4.56, p ˂ 0.00001), SGRQ-total (MD= −9.67, 95%CI −16.23 to −3.11, Z = 2.89, p = 0.004) and SF-36 physical (MD = 4.98, 95%CI 0.60 to 9.35, Z = 2.23, p = 0.03) compared with usual care group. Early PR in AECOPD patients would lead to better 6MWD, mMRC, SGRQ-total and SF-36 physical. But there were no significant effects of the PR group on measures of FEV1% predicted, borg dyspnea score and SF-36 mental.

Pneumologische Frührehabilitation

Die Frührehabilitation ist eine akutstationäre Behandlung noch während oder kurz nach akuter Erkrankung und ist in § 39 im Sozialgesetzbuch (SGB) V verankert. Die Frührehabilitation verfolgt das Ziel, die Beeinträchtigungen der Körperfunktionen zu reduzieren bzw. zu minimieren, die Alltagsfähigkeiten zu verbessern, um letztlich die Teilhabe der PatientInnen zu erreichen. Die pneumologische Frührehabilitation erfolgt im Allgemeinen erst nach erfolgreichem Weaning, während bei neurologischen PatientInnen die Beatmungsentwöhnung Teil der frührehabilitativen Behandlung ist. Die pneumologische Frührehabilitation optimiert den gesamten Behandlungsverlauf von schwerkranken PatientInnen von der Intensiv‑/Weaningstation über die Frührehabilitation bis zur außerklinischen Weiterversorgung und schließt damit eine Lücke in dem Behandlungsverlauf.

Dynamic changes of pulmonary diffusion capacity in survivors of non-critical COVID-19 during the first six months.

SummaryBackgroundThe dynamic trends of pulmonary function in coronavirus disease 2019 (COVID-19) survivors since discharge have been rarely described. We aimed to describe the changes of lung function and identify risk factors for impaired diffusion capacity.MethodsNon-critical COVID-19 patients admitted to the Guangzhou Eighth People's Hospital, China, were enrolled from March to June 2020. Subjects were prospectively followed up with pulmonary function tests at discharge, three and six months after discharge.FindingsEighty-six patients completed diffusion capacity tests at three timepoints. The mean diffusion capacity for carbon monoxide (DLCO)% pred was 79.8% at discharge and significantly improved to 84.9% at Month-3. The transfer coefficient of the lung for carbon monoxide (KCO)% pred significantly increased from 91.7% at discharge to 95.7% at Month-3. Both of them showed no further improvement at Month-6. The change rates of DLCO% pred and KCO% pred were significantly higher in 0–3 months than in 3–6 months. The alveolar ventilation (VA) improved continuously during the follow-ups. At Month-6, impaired DLCO% pred was associated with being female (OR 5.2 [1.7–15.8]; p = 0.004) and peak total lesion score (TLS) of chest CT > 8.5 (OR 6.6 [1.7–26.5]; p = 0.007). DLCO% pred and KCO% pred were worse in females at discharge. And in patients with impaired diffusion capacity, females’ DLCO% pred recovered slower than males.InterpretationThe first three months is the critical recovery period for diffusion capacity. The impaired diffusion capacity was more severe and recovered slower in females than in males. Early pulmonary rehabilitation and individualized interventions for recovery are worthy of further investigations.

Impact of early pulmonary rehabilitation in postacute COVID Disease: A single-center experience from India – A quasi-experimental study

It was observed that post-COVID patients reported persistent exertional dyspnea, cough, fatigue, or chest pain. About 10%-20% of patients may progress to pulmonary fibrosis. Pulmonary rehabilitation has been proven to be useful in improving effort tolerance and quality of life in chronic respiratory diseases. The objective of this study was to assess the effectiveness of pulmonary rehabilitation in improving 6-min walk distance (6 MWD), peak flow, fatigue, anxiety, and depression in early postacute COVID disease. This quasi-experimental study was conducted during January 2021 to March 2021. The patients who recovered from COVID-19 and having persistent exertional dyspnea and fatigue after 3 weeks of recovery were included in the study. Baseline and postintervention assessment of 6 MWD, Visual Analog Scale for Fatigue (VAS-F), peak flow, and Hamilton rating scales (HAM) scales after 4 weeks were done. Compliance was ensured with weakly telemonitoring. Significant improvement in peak flow, 6 MWD, Hamilton Anxiety Rating Scale (HAM-A), Hamilton Depression Rating Scale (HAM-D), and VAS-F (P < 0.01) after 4 weeks of pulmonary rehabilitation. Early pulmonary rehabilitation in post-COVID syndrome can contribute to statistically significant improvement in functional and psychological parameters as well as post-COVID fatigue.

Pulmonary Rehabilitation Programmes Within Three Days of Hospitalization for Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis.

ObjectiveTo evaluate the efficacy and safety of early pulmonary rehabilitation (PR) (ie, <3 days of hospitalization) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).MethodsEmbase, Web of Science, PubMed and Cochrane Library were searched from their inception to 1 April 2021. Randomized controlled trials were included if they observed the efficacy of early PR in AECOPD patients. Study selection, data extraction, risk of bias and quality of evidence were assessed by two researchers independently. Assessment of the risk of bias and eidence quality were evaluated by the Cochrane Collaboration’s tool and Grading of Recommendations, Assessment, Development and Evaluation system, respectively.ResultsFourteen trials (829 participants) were identified. Significant improvement was found in the 6-minute walk distance (6MWD; mean difference (MD): 69.64; 95% CI: 40.26 to 99.01; Z = 4.65, P < 0.0001, low quality). In the subgroup analysis, the exercise-training group showed marked improvement (MD: 96.14; 95% CI: 20.24 to 172.04; Z = 2.48, P = 0.001). The Saint George’s Respiratory Questionnaire (SGRQ) total score was low (MD: −12.77; 95% CI: −16.03 to −9.50; Z = 7.67, P < 0.0001, moderate quality). Significant effects were not found for the duration of hospital stay, quadriceps muscle strength or five times sit to stand test. Only one serious adverse event was reported in experimental group, which was not associated with early PR.ConclusionPR initiated <3 days of hospitalization may increase exercise capacity and improve quality of life, but the results should be interpreted prudently and dialectically, and the role of early PR in AECOPD needs further exploration.

Investigation of the impact of SARS-CoV infection on the immunologic status and lung function after 15\xa0years

BackgroundWe investigate the long-term effects of SARS-CoV on patients’ lung and immune systems 15 years post-infection. SARS-CoV-2 pandemic is ongoing however, another genetically related beta-coronavirus SARS-CoV caused an epidemic in 2003–2004.MethodsWe enrolled 58 healthcare workers from Peking University People’s Hospital who were infected with SARS-CoV in 2003. We evaluated lung damage by mMRC score, pulmonary function tests, and chest CT. Immune function was assessed by their serum levels of globin, complete components, and peripheral T cell subsets. ELISA was used to detect SARS-CoV-specific IgG antibodies in sera.ResultsAfter 15 years of disease onset, 19 (36.5%), 8 (34.6%), and 19 (36.5%) subjects had impaired DL (CO), RV, and FEF25–75, respectively. 17 (30.4%) subjects had an mMRC score ≥ 2. Fourteen (25.5%) cases had residual CT abnormalities. T regulatory cells were a bit higher in the SARS survivors. IgG antibodies against SARS S-RBD protein and N protein were detected in 11 (18.97%) and 12 (20.69%) subjects, respectively. Subgroup analysis revealed that small airway dysfunction and CT abnormalities were more common in the severe group than in the non-severe group (57.1% vs 22.6%, 54.5% vs 6.1%, respectively, p < 0.05).ConclusionsSARS-CoV could cause permanent damage to the lung, which requires early pulmonary rehabilitation. The long-lived immune memory response against coronavirus requires further studies to assess the potential benefit.Trial registration ClinicalTrials.gov, NCT03443102.

Effect of sitting and lying Liuzijue exercise for pulmonary rehabilitation in acute exacerbation of chronic obstructive pulmonary disease patients with non-invasive ventilation: a randomized controlled trial.

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) will lead to the aggravation of respiratory symptoms and accelerate the progression of the disease. So early pulmonary rehabilitation is essential for patients with AECOPD. We aimed to investigate the effect of sitting and lying Liuzijue in AECOPD patients with non-invasive ventilation. A total of 80 AECOPD patients with non-invasive ventilation were randomly divided into two groups. The controlled group (CG) (n=40) received AECOPD conventional treatment and nursing, and the sitting and lying Liuzijue exercise group (LG) (n=40) received sitting and lying Liuzijue therapy. Participants in the LG were required to take this training for 3 months, 30 minutes once every morning and evening. Pulmonary function test, 6-minute walking test (6MWT), Modified Medical Research Council Dyspnea Scales (mMRC), and the St George's Respiratory Questionnaire (SGRQ) were evaluated before and after the intervention. Blood gas was measured before treatment, 3 days, and 5 days after treatment. In addition, the length of hospital stay, the duration of non-invasive ventilation, and the frequency of acute exacerbation within 6 months after the intervention were compared. Seventy patients completed the study. The pulmonary function, 6MWT, mMRC scores, SGRQ, and pH, were significantly improved in the LG. Meanwhile, the 6MWT of the CG was improved. The comparison between the groups showed that the improvement of the pulmonary function, 6MWD, mMRC scores, SGRQ, the duration of non-invasive ventilation, and the frequency of acute exacerbation within 6 months of the LG group differed significantly from the CG. Sitting and lying Liuzijue exercise methods significantly improved lung function, exercise endurance, and quality of life in AECOPD patients with non-invasive ventilation.
