Effectiveness of Pulmonary Rehabilitation in Interstitial Lung Disease, Including Coronavirus Diseases: A Systematic Review and Meta-analysis.

OBJECTIVE: A meta-analysis of randomized controlled trials (RCTs) was conducted to determine the effect of pulmonary rehabilitation on functional capacity and quality of life in interstitial lung diseases, including those caused by coronaviruses. DATA SOURCES: MEDLINE, EMBASE, SPORTDiscus, Cochrane Library, Web of Science, and MedRxiv from inception to November 2020 were searched to identify documents. STUDY SELECTION: Publications investigating the effect of pulmonary rehabilitation on lung function (forced vital capacity [FVC]), exercise capacity (6-minute walk distance [6MWD]), health related quality of life (HRQOL), and dyspnea were searched. DATA EXTRACTION: The data were extracted into predesigned data extraction tables. Risk of bias was evaluated with the Cochrane Risk of Bias tool (RoB 2.0). DATA SYNTHESIS: A total of 11 RCTs with 637 interstitial lung disease patients were eligible for analyses. The pooled effect sizes of the association for pulmonary rehabilitation were 0.37 (95% confidence interval [CI], 0.02-0.71) for FVC, 44.55 (95% CI, 32.46-56.64) for 6MWD, 0.52 (95% CI, 0.22-0.82) for HRQOL, and 0.39 (95% CI, -0.08 to 0.87) for dyspnea. After translating these findings considering clinical improvements, pulmonary rehabilitation intervention increased predicted FVC by 5.5%, the 6MWD test improved by 44.55 m, and HRQOL improved by 3.9 points compared with baseline values. Results remained similar in sensitivity analyses. CONCLUSIONS: Although specific evidence for pulmonary rehabilitation of coronavirus disease 2019 patients has emerged, our data support that interstitial lung disease rehabilitation could be considered as an effective therapeutic strategy to improve the functional capacity and quality of life in this group of patients.

Rehabilitation and COVID-19: the Cochrane Rehabilitation 2020 rapid living systematic review. Update as of July 31st, 2020.

INTRODUCTION: This paper is the first update of the second edition of the rapid living systematic review on the latest scientific literature informing rehabilitation of patients with COVID-19 and/or describing consequences of the disease and its treatment, as they relate to limitations in functioning of rehabilitation interest. The aim of this study was to report data of a systematic search performed on papers published in July 2020. EVIDENCE ACQUISITION: The methodology described in the second edition of the rapid living systematic review was applied to search eligible papers included in the databases between July 1, 2020 and July 31, 2020. EVIDENCE SYNTHESIS: Eight-hundred-ninety-two papers were identified through database searching (after removal of duplicates); of these, only 23 studies were included. According to OCEBM 2011 Levels of Evidence Table, they were level 3 in 30.5% cases and level 4 in 69.5%. No RCT was found. Nineteen papers studied COVID-19 patients, assessed in the acute (10 studies), post-acute (8 studies) and chronic phase (one study). Four studies reported data on the impact of COVID-19 on subjects with pre-existing health conditions. CONCLUSIONS: The current literature production still focuses more on describing all the possible aspects and complications of the pathology than on interventions or new organization models to deal with it. Albeit evidence on handling COVID-19 from a rehabilitative point of view is improving each month, further studies are still mandatory to report the role of rehabilitation in this scenario.

CAMPO DE APLICACIÓN: Este documento está diseñado para ser aplicado en el domicilio de los pacientes adultos y pediátricos ingresados a las Unidades de Hospitalización Domiciliaria (UHD) con sospecha de infección por SARS-CoV-2 o con resultado positivo para COVID-19

PURPUSE: Given the health crisis that the country and the world are currently experiencing, this document was prepared by the autonomous initiative of kinesiologists from twelve Hospital at Home units of public hospitals in Chile, in order to unify criteria based on their experiences and the available scientific evidence in order to carry out safe respiratory physiotherapy care in patients with suspected or confirmed COVID-19. In addition, this document is intended to be a guide for those who need to protocolize and / or standardize their care at Hospital at home, and can be adapted according to the need and availability of resources and infrastructure of each unit. It is important to note that this document may vary depending on the evolution of this pandemic and the updating of scientific evidence. SCOPE: This document is designed to be applied in the home of adult and pediatric patients admitted to Hospital at Home Units (UHD) with suspected SARS-CoV-2 infection or with a positive result for COVID-19

"The post-COVID era": challenges in the treatment of substance use disorder (SUD) after the pandemic.

BACKGROUND: Citizens affected by substance use disorders are high-risk populations for both SARS-CoV-2 infection and COVID-19-related mortality. Relevant vulnerabilities to COVID-19 in people who suffer substance use disorders are described in previous communications. The COVID-19 pandemic offers a unique opportunity to reshape and update addiction treatment networks. MAIN BODY: Renewed treatment systems should be based on these seven pillars: (1) telemedicine and digital solutions, (2) hospitalization at home, (3) consultation-liaison psychiatric and addiction services, (4) harm-reduction facilities, (5) person-centered care, (6) promote paid work to improve quality of life in people with substance use disorders, and (7) integrated addiction care. The three "best buys" of the World Health Organization (reduce availability, increase prices, and a ban on advertising) are still valid. Additionally, new strategies must be implemented to systematically deal with (a) fake news concerning legal and illegal drugs and (b) controversial scientific information. CONCLUSION: The heroin pandemic four decades ago was the last time that addiction treatment systems were updated in many western countries. A revised and modernized addiction treatment network must include improved access to care, facilitated where appropriate by technology; more integrated care with addiction specialists supporting non-specialists; and reducing the stigma experienced by people with SUDs.

COVID-19 Guide for the Rehabilitation Clinician: A Review of Nonpulmonary Manifestations and Complications.

Severe acute respiratory syndrome coronavirus 2-also known as COVID-19-is primarily known for respiratory illness. Although it is clear that patients with moderate to severe cases of COVID-19 will require pulmonary rehabilitation, physiatrists will need to consider effective management plans for COVID-19 survivors with extrapulmonary involvement. This report will summarize key nonpulmonary considerations to guide rehabilitation clinicians who may be involved in the care of COVID-19 survivors with the best available early evidence.

[Post-traumatic stress disorder in convalescent patients of severe acute respiratory syndrome: (1)H-MRS study].

OBJECTIVE: To ascertain the metabolic changes in patients of severe acute respiratory syndrome (SARS) and SARS-related post-traumatic stress disorder (PTSD) and elucidate the relationship between PTSD, SARS and brain metabolism. METHODS: A total of 58 convalescent SARS patients were evaluated by the scores of impact of event scale (IES), self-rating anxiety scale (SAS) and self-rating depression scale (SDS), etc. And 44 of them participated in (1)H-MRS study. There were 18 patients (M:F = 6:12) with SARS-related PTSD and 26 convalescent SARS patients without PTSD. And the procedures were repeated in 18 age, gender and education-matched normal control subjects. In all patients and controls, the regions of interest on magnetic resonance spectroscopy (MRS) were anterior cingulate gyrus (ACG), posterior cingulate gyrus (PCG), left anterior periventricular white matter (LAPWM) and left posterior periventricular white matter (LPPWM). And the correlations between MRS findings and the scores of SAS, SDS and IES were evaluated. RESULTS: In comparisons with the control subjects (n = 18) and convalescent SARS patients without PTSD (n = 26), the SARS-related PTSD group (n = 18) had significantly lower N-acetylaspartate/creatine (NAA/Cr) in 4 regions of interest while the NAA/Cr of the convalescent SARS patients was significantly lower than controls in 3 regions of interest (ACG, PCG and LAPWM). The ratios of NAA/Cr showed no close correlation with the scores of IES, SAS and SDS in convalescent SARS patients. CONCLUSION: The changes of brain metabolism in PTSD are caused by SARS. But their exact relationship awaits further explorations. SARS may also lead to the changes of brain metabolism.

Medical social work practice and SARS in Singapore.

This article reports on the findings of a qualitative study exploring the impact of SARS on social work practice in five different hospitals in Singapore. The study sought to examine the range of interventions adopted by 28 medical social workers and the theoretical orientations underpinning them. The findings discussed include the impact of infection control practices on social work intervention, the range of interventions undertaken, respondents' reflections and self-awareness, the role of values and ethics, creativity and training, and their recommendations for future emergencies. While the findings of the study relate specifically to hospital social work practice, the crisis and trauma nature of the work makes it applicable to a broader range of practice in these areas and a range of populations. The findings from this study could also inform the development of training programs for social work and other clinical health workers, and emergency management planning.

[Changes in pulmonary function in SARS patients during the three-year convalescent period].

OBJECTIVE: To investigate the patterns of pulmonary function in severe acute respiratory syndrome (SARS) patients during three-year convalescent period, and to investigate the changes and the medium and long term effects on pulmonary function of SARS patients. METHODS: Pulmonary function tests were conducted for four times in 37 SARS patients during three-year convalescent period. They were discharged from hospital within one month, three months, one year and three years respectively. At the same time, pulmonary function of 15 healthy persons was examined as controls to be used for comparison. RESULTS: Compared with the healthy controls, there were significant decrease in forced vital capacity (FVC), vital capacity (VC), one second forced expiratory volume (FEV1), 25%-75% forced expiratory flow (25%-75%FEF) of SARS patients within three years after their discharge from hospital (all P<0.05). There were no significant differences in FEV1/FVC, total lung capacity (TLC), diffusing capacity of the lung for carbon monoxide (DLCO) between the two groups (all P>0.05). Abnormality rate of DLCO in the SARS patients within three years after discharge was significantly decreased (32.4% vs. 5.4%,P<0.05), but no significant differences in FVC, VC, 25%-75%FEF among SARS patients discharged one month and three years from the hospital (all P>0.05). Ten SARS patients showed lower FVC (mild degree in 9 cases, severe degree in 1 case) three years later, 2 patients showed mildly lowered DLCO. CONCLUSION: The lung diffusion function of the SARS patients had recovered after they were discharged from hospital within three years, but in 20%-30% patients there is still mild or moderate restrictive ventilation function abnormality and small airway function impairment. The lung functions of most patients have recovered gradually, but in a minority of patients they may be impaired.

One-year outcomes and health care utilization in survivors of severe acute respiratory syndrome.

BACKGROUND: Severe Acute Respiratory Syndrome (SARS) became a global epidemic in 2003. Comprehensive information on 1-year outcomes and health care utilization is lacking. Research conducted during the SARS outbreak may help inform research planning for future public health emergencies. The objective of this study was to evaluate the 1-year outcomes in survivors of SARS and their family caregivers. METHOD: The study was prospective and observational. We evaluated 117 SARS survivors from Toronto, Ontario. Patients were interviewed and underwent physical examination, pulmonary function testing, chest radiography, a 6-minute-walk test, quality-of-life measures, and self-report of health care utilization. At 1 year, informal caregivers were identified for a survey on caregiver burden. RESULTS: The enrolled survivors of SARS were young (median age, 42 years), and most were women (67%) and health care workers (65%). At 1 year after hospital discharge, pulmonary function measures were in the normal range, but 18% of patients had a significant reduction in distance walked in 6 minutes. The Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) domains were 0.3 to 1.0 SD below normal at 1 year. Of the patients, 17% had not returned to work by 1 year. Fifty-one patients required 668 visits to psychiatry or psychology practitioners. During the SARS epidemic, informal caregivers reported a decline of 1.6 SD below normal on the mental component score of the SF-36. CONCLUSIONS: Most SARS survivors had good physical recovery from their illness, but some patients and their caregivers reported a significant reduction in mental health 1 year later. Strategies to ameliorate the psychological burden of an epidemic on the patient and family caregiver should be considered as part of future pandemic planning.

Quality of life and psychological status in survivors of severe acute respiratory syndrome at 3 months postdischarge.

BACKGROUND: Little is known about the long-term consequence of severe acute respiratory syndrome (SARS). We carried out an assessment on SARS patients after their recovery from their acute illness. METHOD: Postal survey comprising Health-Related Quality of Life (HRQoL) questionnaires and anxiety and depression measures was sent to them at 3 months' postdischarge. RESULTS: There was a significant impairment in both the HRQoL and mental functioning. Forty-one percent had scores indicative of a posttraumatic stress disorder (PTSD); about 30% had likely anxiety and depression. CONCLUSION: SARS has significant impact on HRQoL and psychological status at 3 months.

A randomised controlled trial of the effectiveness of an exercise training program in patients recovering from severe acute respiratory syndrome.

The aim of this study was to evaluate the effectiveness of an exercise training program on cardiorespiratory and musculoskeletal performance and health-related quality of life of patients who were recovering from severe acute respiratory syndrome (SARS). A 6-week supervised exercise training program was carried out in the physiotherapy department of a university teaching hospital. One hundred and thirty-three patients referred from a SARS Review Clinic solely for physiotherapy were included. Cardiorespiratory fitness (6-minute walk test, Chester Step Test for predicting VO(2max)), musculoskeletal performance (isometric deltoid and gluteal muscles strength, handgrip strength, 1-minute curl-up and push-up tests) and health-related quality of life (SF-36) were measured and evaluated. Patients were assigned randomly to either a control group (standardised educational session about exercise rehabilitation) or an exercise group. After 6 weeks, significantly greater improvement was shown in the exercise group in the 6-minute walk test (77.4 m vs 20.7 m, p < 0.001), VO(2max) (3.6 ml/kg/min vs 1 ml/kg/min, p = 0.04), and musculoskeletal performance (handgrip strength, curl-up and push-up tests, p < 0.05). Effects on health-related quality of life were not statistically significant. It was concluded that the exercise training program was effective in improving both the cardiorespiratory and musculoskeletal fitness in patients recovering from SARS. However, health-related quality of life was not affected by physical training.

Follow-up study on pulmonary function and lung radiographic changes in rehabilitating severe acute respiratory syndrome patients after discharge.

OBJECTIVES: To follow-up on the changes in lung function and lung radiographic pictures of severe acute respiratory syndrome (SARS) patients discharged from Xiaotangshan Hospital in Beijing (by regularly receiving examination), and to analyze retrospectively the treatment strategy in these patients. METHODS: Surviving SARS patients were seen at least twice within 3 months after discharge and underwent SARS-associated coronavirus (SARS-CoV) IgG antibody testing, pulmonary function testing, and chest radiography and/or high-resolution CT (HRCT) examinations at Chinese PLA General Hospital. The treatments received at Xiaotangshan Hospital were analyzed retrospectively and were correlated to later status. RESULTS: Positive SARS-Co virus IgG antibody results were seen in 208 of 258 patients, with 21.3% (55 of 258 patients) still having a pulmonary diffusion abnormality (D(LCO) < 80% of predicted). By comparing the 155 survivors with positive SARS-CoV IgG antibody results and D(LCO) > or = 80% predicted with the 50 patients with negative SARS-CoV IgG results, we found that 53 patients with positive SARS-CoV IgG results and a lung diffusion abnormality had endured a much longer course of fever and received larger doses of glucocorticoid, as well as higher ratios of oxygen inhalation and noninvasive ventilation treatment. For these patients, 51 of 53 patients with positive SARS-CoV IgG results and a lung diffusion abnormality underwent pulmonary function testing after approximately 1 month. D(LCO) improved in 80.4% of patients (41 of 51 patients). Of the patients with a lung diffusion abnormality, 40 of 51 patients showed lung fibrotic changes in the lung image examination and 22 patients (55%) showed improvement in lung fibrotic changes 1 month later. CONCLUSION: These findings suggest that lung fibrotic changes caused by SARS disease occurred mostly in severely sick patients and may be self-rehabilitated. D(LCO) scores might be more sensitive than HRCT when evaluating lung fibrotic changes.

[Prognostic analysis of lung function and chest X-ray changes of 258 patients with severe acute respiratory syndrome in rehabilitation after discharge].

OBJECTIVE: To analyze the clinical characteristics and prognostic changes of rehabilitating severe acute respiratory syndrome (SARS) patients through regular lung function tests and lung imaging studies after discharge and to retrospectively analyze the treatment data of these patients. METHODS: 258 discharged SARS patients received regular SARS-Co virus IgG test, lung function test and chest X-ray and/or high resolution computerized tomography (HRCT) examination at General Hospital of PLA two months after discharge, and the treatment data of these patients were retrospectively analyzed. RESULTS: 80.6% patients (208 of 258 patients) were positive for SARS-Co virus IgG. 21.3% patients (55 of 258 patients) showed lung diffusion abnormity (D(LCO) < 80%pred). Compared to 155 SARS-Co virus IgG positive patients without lung diffusion abnormity and 50 SARS-Co virus IgG negative patients, the 53 SARS-Co virus IgG positive patients with lung diffusion abnormity had longer fever course, higher dosages of glucocorticoid therapy, higher percentage of oxygen therapy and non-invasive ventilation. 51 of the 53 patients with lung diffusion abnormity received lung function test after one month, and the results of D(LCO) improved in 80.4% patients (41 of 51 patients). 40 of 51 patients with lung diffusion abnormity showed lung fibrosis, and the fibrosis decreased in 55% patients (22 of 40 patients) after one month. CONCLUSIONS: This finding suggests that lung fibrosis caused by SARS mostly occurs in severe patients, and it can resolve spontaneously. D(LCO) may be more sensitive than HRCT in evaluating the fibrotic changes.

[Evaluation on effect of integrative medical treatment on quality of life of rehabilitation stage in 85 patients with SARS].

OBJECTIVE: To evaluate the effect of integrative medical treatment (IMT) with serial Chinese recipes on quality of life (QOF) of rehabilitation stage in SARS patients. METHODS: Eighty-five SARS patients of rehabilitation stage were enrolled in the clinical study. They were divided into the IMT group (62 patients received serial Chinese recipes and western medicine) and the control group (23 patients received western medicine alone). The serial Chinese recipes were given according to patients' syndrome, one dose per day for oral intake for 3 weeks. QOF scoring in patients was observed. RESULTS: QOF scoring in the IMT group before treatment was not significantly different from that in the control group. After 3 weeks treatment, it improved to some extent in both groups, but the improvement in the IMT group was superior to that in the control group in respect of total score and score of psychologic emotional factors. CONCLUSION: Serial Chinese recipe could improve QOF of rehabilitation stage in SARS patients.
