Effects of Baduanjin Exercise on lung function and 6 min walk in COPD patients: a systematic review and meta-analysis.

COPD is a public health problem of global concern, which seriously affects the quality of life of patients and is also the third leading cause of death from non-communicable diseases. To investigate the effect of Ba duan jin exercise on lung function and the results of a 6-min walking trial in patients with stable COPD. Literature databases such as Web of Science, Embase, PubMed, Cochrane Library, Chinese Biomedical Literature (CBM), CNKI, Wanfang Data and VIP were searched by computer, the search period is up to January 2024. Literature screening, quality evaluation and data extraction were carried out independently by two researchers. And use RevMan 5.3 software and StataMP 18 (64-bit) software to process the relevant outcome indicators. A total of 16 RCT studies with 1184 patients were included. The meta-analysis results showed that compared with the control group, Ba Duan Jin exercise could improve FEV1 (MD = 0.29, 95% CI (0.20, 0.37), P < 0.0001), FEV1/FVC (%) (MD = 3.86, 95% CI (2.24, 5.47), P < 0.00001), and 6-min walking distance (MD = 45.41, 95% CI (33.93, 56.89), P < 0.00001) in stable COPD patients. The results of subgroup analysis based on the duration of the intervention cycle, research quality, and intervention frequency showed that periodic Ba Duan Jin exercise can significantly improve the relevant lung function levels to varying degrees. At the same time, the intervention effect of Ba Duan Jin exercise during the implementation process is also affected by the duration of the exercise cycle, exercise frequency, and the completion of the exercise plan. Ba Duan Jin exercise has a positive improvement effect on lung function and 6-min walking distance in stable COPD patients. In the process of exercise implementation, attention should be paid to cultivating exercise habits, stabilizing and improving attendance rates, and strictly implementing training techniques to achieve the best clinical outcomes for these patients.

Active video games as an adjunct to pulmonary rehabilitation of patients with Chronic Obstructive Pulmonary Disease: a commentary on a systematic review.

Pulmonary rehabilitation is a key evidence-based intervention to improve the outcomes of people living with Chronic Obstructive Pulmonary Disease (COPD). However, there are challenges in delivering pulmonary rehabilitation including reduced referral rates and suboptimal uptake and completion rates. Active video game interventions, when used as an adjunct, may increase the adoption of and access to pulmonary rehabilitation. This commentary summarises and critically appraises a systematic review which investigated the effectiveness of active video games as a supplementary component in the pulmonary rehabilitation of individuals suffering from chronic obstructive pulmonary disease.

Progress in Research into the Effectiveness of Pulmonary Rehabilitation in Children with Asthma - A Narrative Review.

Asthma is the most common chronic respiratory disease in children. It has a serious impact on children's physical and mental health. Pulmonary rehabilitation is a multidisciplinary and comprehensive intervention for patients with chronic respiratory disease, whose major components include breathing training, inspiratory muscle training and exercise training. Pulmonary rehabilitation is a multidisciplinary and comprehensive intervention for patients with chronic respiratory diseases, the main components of which are breathing training, inspiratory muscle training and exercise training. Pulmonary rehabilitation can improve the physical and mental condition of patients with chronic respiratory diseases and promote healthy behaviors. However, there is little research on pulmonary rehabilitation in children with asthma. This review comprehensively evaluated the effect of pulmonary rehabilitation in children with asthma at home and abroad, aiming to provide reference for clinical research on pulmonary rehabilitation in children with asthma.

Effects of home-based telerehabilitation-assisted inspiratory muscle training in patients with idiopathic pulmonary fibrosis: A randomized controlled trial.

BACKGROUND AND OBJECTIVE: There are few studies that have used inspiratory muscle training (IMT) as an intervention for patients with isolated idiopathic pulmonary fibrosis (IPF). This study aimed to investigate and interpret the effects of home-based telerehabilitation-assisted IMT in patients with IPF. METHODS: Twenty-eight participants with IPF took part in the study. Lung function tests, functional exercise capacity by 6-min walk distance (6MWD), dyspnoea perception by modified medical research council dyspnoea scale (mMRC), and inspiratory muscle strength by maximal inspiratory pressure (MIP) were assessed. IMT was performed twice a day, 7 days/week, for 8 weeks. The intervention group (n = 14) performed IMT at 50% of their baseline MIP while the control group (n = 14) performed IMT without applied resistance. Loading intensity was progressed by keeping the load at 4-6 on a modified Borg scale for the highest tolerable perceived respiratory effort for each patient. RESULTS: Dyspnoea based on mMRC score (p < 0.001, η2 effect size = 0.48) significantly decreased within the intervention group compared with the control group. There were significant increases in the intervention group compared to the control group based on 6MWD (p < 0.001, η2 effect size = 0.43), MIP (p = 0.006, η2 effect size = 0.25) and MIP % predicted (p = 0.008, η2 effect size = 0.25). CONCLUSION: The findings of this study suggest that an 8-week home-based telerehabilitation-assisted IMT intervention produced improvements in inspiratory muscle strength, leading to improvements in functional exercise capacity and dyspnoea.

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

Objective: This study aimed to evaluate the clinical effectiveness of early pulmonary rehabilitation (PR) treatment methods for stroke-associated pneumonia (SAP). Methods: 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. Results: 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). Conclusion: 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.

Development of a core outcome set for physiotherapy trials in adults with bronchiectasis (the COS-PHyBE study): A Delphi study and consensus meeting.

Background: Physiotherapy is recommended for bronchiectasis management, but there is disparity in evidence supporting its use. This is partly because of inconsistency and poor reporting of outcomes in available studies. A Core Outcome Set (COS) may improve trial consistency and decrease reporting bias. This study aimed to develop a COS for physiotherapy clinical trials in adults with bronchiectasis. Methods: A comprehensive list of outcomes was developed using a systematic review and qualitative semi-structured interviews with patients with bronchiectasis and physiotherapists.An international two-round online Delphi survey was conducted. Outcomes scored 7-9 (crucial) by ≥ 70 % of participants and 1-3 (not that important) by ≤ 15 % of participants from each stakeholder in the Likert scale were nominated for inclusion in the COS. Nominated outcomes and those considered crucial by only one of the stakeholders' groups were further discussed and voted in an international consensus meeting. Results: A list of 137 outcomes was generated; 104 from literature and 33 from interviews. A Delphi survey containing 59 outcomes was completed by 171 participants from 20 countries. After the consensus meeting, representatives agreed on seven outcomes: health-related quality of life, respiratory symptoms, physical functioning, emotional and psychological functioning, fatigue, adherence to treatment, and functional exercise capacity. Conclusion: A minimum set of seven outcomes are recommended to be included as measurements in future trials evaluating physiotherapy interventions for bronchiectasis.

Peculiarities of physical therapy of chronic obstructive pulmonary disease: practical experience.

OBJECTIVE: Aim: The aim of the study is todetermine the feasibility of using a home pulmonary rehabilitation program and evaluate its impact on patients with COPD in the GOLD B group. PATIENTS AND METHODS: Materials and Methods: The study was conducted on the basis of the «Healthy Movements¼ studio (Poltava). Patients were involved in the study after receiving secondary (specialized) medical care, the basis of which was physical therapy treatment and exercise therapy in accordance with the clinical protocol approved by the internal order of the health care institution. A total of 30 people (aged 59 to 68.4 years) with II degree chronic obstructive pulmonary disease (50 % ≤ FEV1 < 80 % of normal) in remission took part in the study. Research methods: pedagogical, medical and biological , methods of mathematical statistics. RESULTS: Results: Each patient confirmed the achievement of the general goal, namely, increasing the number of therapeutic exercises from 3 to 5 times a week, improving the quality of life, more active participation in improving their health and awareness of the disease. The patients considered self-management training to be the most valuable. CONCLUSION: Conclusions: Pulmonary rehabilitation is indicated for all patients, regardless of the degree of the disease. The most ef f ective are 6-12 week programs that include breathing exercises, self-management training and training of the patient's environment, strengthening exercises, psychological support, diet therapy.

Investigation of Inspiratory Muscle Training Efficiency Before Bronchoscopic Lung Volume Reduction: A Randomized Controlled Trial.

INTRODUCTION: Pulmonary rehabilitation (PR) is recommended prior to bronchoscopic lung volume reduction (BLVR) procedures to optimize patient outcomes. However, there's a lack of clear guidance on PR content. The aim of our study is to examine the effect of adding inspiratory muscle training (IMT) to standard PR before BLVR on exercise capacity, dyspnea, fatigue level and quality of life. METHODS: Sixty-four patients were randomly assigned to either the PR Group (PRGr) or the PR with IMT group (IMTGr). Both groups underwent an 8-week standard PR program, including breathing exercises, muscle strengthening, and walking. Additionally, IMTGr received IMT sessions. Outcome measures comprised six-minute walking distance (6MWD), maximal inspiratory and expiratory pressures (MIP, MEP), peripheral muscle strength, modified Medical Research Council dyspnea score, fatigue symptom scale, spirometric parameters, Saint George Quality of Life Questionnaire (SGRQ), International Physical Activity Questionnaire Short Form (IPAQ-SF), and Hospital Anxiety and Depression Scale. RESULTS: Our study found no significant difference in exercise capacity improvement between IMTGr and PRGr. However, IMTGr showed significant improvement in MIP compared to PRGr. Both groups experienced improvements in dyspnea, fatigue, and depression scores, as well as enhancements in 6MWD, MEP, peripheral muscle strength, IPAQ-SF and SGRQ scores. CONCLUSION: Adding IMT to PR did not show a significant difference between groups among BLVR-eligible patients. However, improved respiratory muscle strength may have positive clinical implications. Further research is needed to explore short and long-term effects.

Reflections on the challenges of conducting an international multicentre randomized controlled trial of balance training in addition to pulmonary rehabilitation and its impact on fall incidence in people with COPD.

BACKGROUND: Pulmonary rehabilitation (PR) is accepted as standard care for individuals with COPD. We conducted an international, multi-centred randomized controlled trial (RCT) to determine if adding balance training to PR would reduce the incidence of falls in people with COPD. While there have been many trials investigating the effectiveness of PR, few have involved international collaboration. Successful execution of rehabilitation trials requires a significant investment of time, staffing, and resources. With the recent completion of the Balance Training for Fall Reduction in COPD RCT, we report on the design, implementation, and execution of our trial using project management phases. We also highlight our lessons learned for consideration in future multi-centre rehabilitation trials. METHODS: This was a retrospective review of the planning, preparation, timelines, and personnel training involved in the execution of this study using four of the five project management phases described by Farrell et al. in 2010: (1) initiation, (2) planning, (3) execution, and (4) monitoring and controlling. We report descriptive statistics as percentages and counts and summarize our lessons learned. RESULTS: Ten outpatient PR programs in three continents participated. Thirty-one personnel worked on the trial across all sites. Enrolment began in January 2017 and was suspended in March 2020 due to the COVID-19 pandemic. Approximately 1275 patients were screened, 455 (36%) were eligible, 258 (57%) consented, 243 (53%) participated, and 130 (61%) completed the 12-month follow-up assessment. Lessons learned through our experience included (1) ensuring awareness of funder policies and considering the impact on collaborating sites; (2) preparing for the possibility of human resource and program disruptions; (3) anticipating site dropout and having a contingency plan in place; (4) planning and monitoring process measure data before, during, and after trial initiation; (5) ensuring frequent and consistent communication with and between collaborating sites; (6) maximizing features of database platform to ensure data set completeness and controlled data access; and (7) identifying strategies for increasing patient engagement in a high-demand study. CONCLUSIONS: We identify seven lessons learned through our experience conducting an international, multicentre rehabilitation-based RCT. These lessons can provide guidance to other trialists conducting studies with similar logistics and may assist with future trial planning and implementation.

Improvement of diaphragmatic excursion in the supine position in a patient with idiopathic pleuroparenchymal fibroelastosis: A case report.

Idiopathic pleuroparenchymal fibroelastosis (iPPFE) is a rare form of idiopathic interstitial pneumonia. We report a case of a patient with iPPFE in whom postural changes improved diaphragmatic excursion (DE) and exercise tolerance. Chest radiography showed a greater elevation of the diaphragm at maximum expiration in the supine position than the standing position. DE measured by ultrasonography was higher in the supine position than the standing position. The findings may suggest greater diaphragm movement in the supine position, leading to successful rehabilitation and improved exercise endurance. There is no effective treatment for iPPFE; therefore, an innovative treatment strategy is warranted.

Study of the effectiveness of telemedicine-based pulmonary rehabilitation in recovered patients of COVID-19 pneumonitis.

Objective: To determine the effectiveness of the telemedicine-based pulmonary rehabilitation programme in COVID-19 pneumonitis. Design: Prospective intervention study. Setting: Rehabilitation outpatient department, Tertiary-Care institute. Participants: Consecutive sample of patients (N = 50) in recovered COVID-19 infection. Intervention: Six weeks of telemedicine-based pulmonary rehabilitation in recovered patients of COVID-19 infection. Outcome Measures: All patients were clinically assessed by six minutes walk test (6MWT), Modified Medical Research Council Scale (mMRC), 30s-STS and SF 36 at zero week and six weeks post-intervention. Statistical Analysis: Difference in means of pre- and post-intervention was compared using paired t-test. A P value <0.05 was considered statistically significant. Results: The 6MWT, mMRC Scale, 30 seconds sit-to-stand test, and WHO QoL scale-SF 36 were assessed and post-rehabilitation sessions, all the patients' showed improvement in the prescribed parameters. After six weeks of respiratory rehabilitation, the distance covered in the 6MWT was significantly longer than that of before the intervention. There was a significant difference between zero and six weeks during the PR intervention. mMRC and 30s-STS results showed a significant difference between zero and six weeks (2.36 ± 0.598, 4.54 ± 1.94. Quality of life improved significantly after six weeks of pulmonary rehabilitation in eight domains of the SF-36. Conclusion: Six-week pulmonary rehabilitation programme delivered through telemedicine platform improves respiratory function, QoL and anxiety in patients with post-COVID-19 pneumonia during a recovery phase.

Relevance of multidimensional dyspnea assessment in the context of pulmonary rehabilitation.

Objectives: While dyspnea is the main symptom in chronic obstructive pulmonary disease (COPD), it is often inadequately evaluated in pulmonary rehabilitation (PR), as it is typically measured using only the impact dimension (ID). However, dyspnea is a multidimensional construct including perception (PD) and emotional (ED) domains. Our work aimed to study the complementarity of dyspnea dimensions and their respective ability to identify different evolutions during PR. Methods: 145 people with COPD attending PR were included in this retrospective study. Dyspnea scores from the modified Medical Research Council scale (ID) and the Multidimensional Dyspnea Profile questionnaire (PD/ED), exercise capacity, quality of life at the start (T1) and the end of PR (T2) were collected from existing databases/medical files. The evolution of each dyspnea dimension was evaluated using the delta score between T2-T1. PR response was defined using the minimal clinically important difference. Results: Our results show that each dyspnea dimension was associated with different health-outcomes. Positive correlations were found between PD-ED at baseline and between their T2-T1 delta score (ρ = 0.51; ρ = 0.41 respectively, p < .01), but there was no significant correlation between ID-PD or -ED (p > .05). 51% of the patients did not respond on ID, but 85% of them nonetheless responded on either PD or ED. Finally, 92% of patients responded on at least one dimension after PR. Discussion: Our study emphasizes the significance of assessing each dimension of dyspnea independently and complementary, as dimensions are associated with different elements and evolve differently under PR effects. This approach is crucial to identifying weak points and allows professionals to focus on program elements that most effectively address the specific dimension causing problems.

The effect of pulmonary rehabilitation on cardiovascular risk, oxidative stress and systemic inflammation in patients with COPD.

PURPOSE: Chronic obstructive pulmonary disease (COPD) is a leading cause of death, and cardiovascular (CV) comorbidities play a role. Evidence of the pulmonary rehabilitation (PR) effect in reducing the CV risk (CVR) in COPD patients is limited. In this study, we aimed to determine the impact of an 8-week PR program (PRP) on the CVR of the overall population and to compare the impact on the exacerbator versus non-exacerbator patients. PATIENTS AND METHODS: This was a prospective study that included adults who had post-bronchodilator forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) (FEV1/FVC) ratio <70 % and FEV1 <80 % predicted, had quit smoking for at least 1 year and had a history of tobacco consumption greater than 10 packs/year, and were clinically stable in the last 8 weeks. Pre- and post-PRP assessments included respiratory function evaluation, laboratory tests, and exercise capacity assessment (6-min walking test [6MWT]). CVR was assessed using different risk prediction models. RESULTS: A total of 50 patients (28 exacerbators and 22 non-exacerbators) completed the PRP (median age: 64.5 years, men: 72 %; arterial hypertension: 70 %, dyslipidemia: 30 %, diabetes: 20 %; CV disease (CVD): 24 %. After the PRP, exacerbator patients showed a significant decrease in the CVR calculated by the COPDCoRi model (p < 0.001); patients with ≥30-m increase on the 6MWT showed statistically significant lower levels of glucose (p = 0.004), HbA1c (p = 0.004) and BODE index score (p = 0.026) compared to patients with <30-m increase. CONCLUSIONS: PR reduced certain modifiable CVR factors and CVD risk, especially in exacerbator patients.

Effectiveness of preoperative and perioperative pulmonary rehabilitation nursing program for the management of patients undergoing thoracic surgery: A systematic review and meta-analysis.

Background & Objective: Several studies have investigated the effectiveness of preoperative or perioperative pulmonary rehabilitation in thoracic surgery patients, but the results are inconsistent and inconclusive. This study attempts to summarize the existing data on the effect of the preoperative and perioperative pulmonary rehabilitation nursing program for the management of patients undergoing thoracic surgery. Methods: Systematic search was done in PubMed Central, SCOPUS, EMBASE, MEDLINE, Google Scholar, and ScienceDirect for papers published until December 2022 and reporting data of postoperative complications and pulmonary health status in patients undergoing thoracic surgery and receiving preoperative or perioperative pulmonary rehabilitation nursing intervention or standard care. Meta-analysis was done by random-effects model and pooled standardised mean differences (SMD) or odds ratios (OR) along with 95% confidence intervals (CIs) were reported. Results: Eighteen studies were included and analysed. Pooled SMD was 0.44 (95%CI: -0.21 to 1.08) for forced expiratory volume (FEV-1), -0.34 (95%CI: -0.94 to 0.26) for peak expiratory flow (PEF), 0.61 (95%CI: -0.60 to 1.81) for forced vital capacity (FVC), 0.42 (95%CI: -0.13 to 0.98) for diffusing capacity of carbon monoxide (DLCO). Pooled SMD for length of hospital stay was -0.64 (95%CI: -1.09 to -0.19). Pooled OR was 0.87 [95%CI: 0.32 to 2.37] for all-cause mortality, 0.35 [95%CI: 0.25 to 0.50] for postoperative pulmonary complications, 0.98 [95%CI: 0.45 to 2.12] for respiratory failure, 0.52 [95%CI: 0.38 to 0.78] for pneumonia and 0.50 [95%CI: 0.33 to 0.76] for atelectasis. Conclusion: Perioperative pulmonary rehabilitation nursing program is effective in reducing the postoperative lung complications and shortening the length of hospital stay in patients undergoing thoracic surgery.

A survey exploring the needs, preferences, and challenges of the key stakeholders for participating in and developing pulmonary rehabilitation in Pune, India.

Considering a huge burden of chronic respiratory diseases (CRDs) in India, there is a need for locally relevant Pulmonary rehabilitation (PR) services. This cross-sectional survey was aimed to explore the interest, needs and challenges among various stakeholders for PR in Pune city, India. At the outpatient respiratory medicine department of a multi-speciality hospital in Pune, India, 403 eligible people with CRDs were invited to participate in the survey, of which 370 (92%) responded and agreed to participate. (220 males, mean ± SD age 56 ± 15 years). Out of the 370, 323 (87%) people with CRDs were keen to attend PR. In a multiple selection question, there was inclination towards paper-based manuals home-based (70%) and web-based (84%) programs. 207 healthcare providers (HCPs), including physicians, pulmonologists and physiotherapists involved in the care of people living with CRDs across Pune city were invited to participate in the survey. Out of the 207, (80%) of the HCPs believed that PR was an effective management strategy and highlighted the lack of information on PR and need for better understanding of PR (48%) and its referral process. The surveyed stakeholders are ready to take up PR, identifying specific needs around further knowledge of PR, modes of delivery, and referral processes, that could potentially feed the development of relevant PR programs in the Indian healthcare settings.

The effect of a hybrid structured pulmonary rehabilitation education program for patients with lung cancer with a high risk of postoperative pulmonary complications: A quasi-experimental study.

PURPOSE: The absence of standardized protocols and education are the main obstacles to perioperative pulmonary rehabilitation (PR), especially for patients with high-risk factors of postoperative pulmonary complications (PPCs). We aimed to explore the effect of a hybrid structured pulmonary rehabilitation education program (SPREP) on patients with lung cancer at high risk of PPCs. METHODS: A quasi-experimental trial with a pre-post test design was conducted. The control group (n = 53) adopted routine perioperative pulmonary rehabilitation, while the intervention group (n = 53) received SPREP. Respiratory function, 6-min walk distance, Borg dyspnea scale, quality of life, anxiety-depression scores at admission, discharge, 2 weeks and 3 months post-discharge, and incidence of PPCs were compared between the two groups. RESULTS: There were no significant differences on the 6-min walk distance and Borg Dyspnoea Scale at discharge between the two groups (P > 0.05), whereas the intervention group showed improved performance at the remaining time points (P < 0.05). In addition, the intervention group had improved exercise capacity, pulmonary function and quality of life, reduced levels of anxiety and depression at discharge, 2 weeks post-discharge and 3 months post-discharge (P < 0.05). In addition, incidence of PPCs was significantly reduced in the intervention group, especially postoperative pneumonia. CONCLUSIONS: The SPREP could show significant benefits in enhancing exercise capacity, lung function, and quality of life, while diminishing the occurrence of PPCs and mitigating the levels of anxiety and depression, future large RCT need to further explore the efficacy. TRIAL REGISTRATION: This study was registered with the China Clinical Trial Registration Center (ChiCTR) under the Clinical Trial Registration Number [ChiCTR2200066698].

Rehabilitation Is Associated With Improvements in Post-COVID-19 Sequelae.

BACKGROUND: Post-COVID-19 syndrome has affected millions of people, with rehabilitation being at the center of non-pharmacologic care. However, numerous published studies show conflicting results due to, among other factors, considerable variation in subject characteristics. Currently, the effects of age, sex, time of implementation, and prior disease severity on the outcomes of a supervised rehabilitation program after COVID-19 remain unknown. METHODS: This was a non-randomized case-control study. Subjects with post-COVID-19 sequelae were enrolled. Among study participants, those who could attend an 8-week, supervised rehabilitation program composed the intervention group, whereas those who couldn't the control group. Measurements were collected at baseline and 8 weeks thereafter. RESULTS: Study groups (N = 119) had similar baseline measurements. Participation in rehabilitation (n = 47) was associated with clinically important improvements in the 6-min walk test (6MWT) distance, adjusted (for potential confounders) odds ratio (AOR) 4.56 (95% CI 1.95-10.66); 1-min sit-to-stand test, AOR 4.64 (1.88-11.48); Short Physical Performance Battery, AOR 7.93 (2.82-22.26); health-related quality of life (HRQOL) 5-level EuroQol-5D (Visual Analog Scale), AOR 3.12 (1.37-7.08); Montreal Cognitive Assessment, AOR 6.25 (2.16-18.04); International Physical Activity Questionnaire, AOR 3.63 (1.53-8.59); Fatigue Severity Scale, AOR 4.07 (1.51-10.98); Chalder Fatigue Scale (bimodal score), AOR 3.33 (1.45-7.67); Modified Medical Research Council dyspnea scale (mMRC), AOR 4.43 (1.83-10.74); Post-COVID-19 Functional Scale (PCFS), AOR 3.46 (1.51-7.95); and COPD Assessment Test, AOR 7.40 (2.92-18.75). Time from disease onset was marginally associated only with 6MWT distance, AOR 0.99 (0.99-1.00). Prior hospitalization was associated with clinically important improvements in the mMRC dyspnea scale, AOR 3.50 (1.06-11.51); and PCFS, AOR 3.42 (1.16-10.06). Age, sex, and ICU admission were not associated with the results of any of the aforementioned tests/grading scales. CONCLUSIONS: In this non-randomized, case-control study, post-COVID-19 rehabilitation was associated with improvements in physical function, activity, HRQOL, respiratory symptoms, fatigue, and cognitive impairment. These associations were observed independently of timing of rehabilitation, age, sex, prior hospitalization, and ICU admission.

Late Presentation of Pulmonary Aplasia in Adulthood: A Report of a Rare Case.

Aplasia of the lung is an uncommon congenital anomaly that can resemble several common illnesses radiologically and presents as an opaque hemithorax with ipsilateral displacement of the mediastinum. This case scenario involves a young woman who has been experiencing recurrent pulmonary tract infections and worsening dyspnea since childhood, presenting as pneumonic consolidation on a chest X-ray. The case explores the importance of lung scans, CT pulmonary angiography, and bronchoscopy to elicit the absence of lung parenchyma on one side.
