Telerehabilitación respiratoria en fibrosis quística: experiencia de pacientes, padres y profesionales durante la pandemia de COVID-19. Estudio cualitativo

Introducción: la rehabilitación respiratoria (RR) se recomienda en pacientes con fibrosis quística (FQ). Durante la pandemia de COVID-19 los programas de RR debieron cerrarse o migrar a modalidades de telerehabilitación, imponiendo nuevos desafíos a pacientes y equipos de salud. El objetivo de este estudio fue explorar las percepciones de pacientes, padres y profesionales sobre la transición a la telerehabilitación respiratoria durante la pandemia de COVID-19. Método: estudio cualitativo. Se consideraron pacientes con FQ mayores de 8 años. También a padres y equipos de salud. El tamaño muestral se determinó mediante saturación teórica. Se realizaron entrevistas semiestructuradas y grupos focales vía Zoom. El análisis de datos se realizó mediante los métodos de codificación abierta y axial. El análisis se realizó utilizando el software Atlas. Ti 7.5.7. Resultados: se incluyó a 4 pacientes adultos, 1 pediátrico y 2 padres, además de 4 profesionales de equipos de salud. Existió una percepción general positiva respecto a la RR y la telerehabilitación. Entre las barreras destacó la falta de equipamiento para la telerehabilitación en domicilio y la organización diaria de los pacientes. Entre los facilitadores destacó la disponibilidad de equipos y redes que permitieran la conectividad y el apoyo familiar. Existió una valoración positiva hacia la continuidad de la telerehabilitación en la etapa post pandémica. Conclusiones: la telerehabilitación fue percibida como una alternativa viable y efectiva, sin embargo, aspectos de la conectividad, disponibilidad de equipamiento y la rutina diaria de los pacientes debe ser considerada a la hora de implementar modalidades telemáticas de atención.

Introduction: Pulmonary rehabilitation (PR) is recommended in patients with Cystic Fibrosis (CF). During the COVID-19 pandemic, PR programs had to migrate to telerehabilitation modalities, imposing new challenges for patients and health teams. The objective of this study was to explore the perceptions of patients, parents, and professionals regarding the transition to respiratory telerehabilitation experienced during the COVID-19 pandemic. Method: Qualitative study. Parents and health teams were included in the case of patients with CF over eight years old. Theoretical saturation determined the sample size. Semi-structured interviews and focus groups were conducted using the Zoom platform. Data analysis was carried out using open and axial coding methods. The analysis was performed using Atlas Ti software 7.5.7. Results: Four adult patients, one pediatric patient, two parents, and four health team professionals entered the study. There was a positive perception regarding PR and telerehabilitation. Among the barriers, the lack of equipment for telerehabilitation at home and the daily organization of patients stood out. Among the facilitators, the availability of equipment and networks that allowed connectivity and family support stood out. Patients rated the continuity of telerehabilitation in the post-pandemic stage positively. Conclusions: Telerehabilitation was perceived as a viable and effective alternative; however, aspects related to connectivity, availability of equipment, and the daily routine of patients must be considered when implementing telematics care modalities.

Effects of a pulmonary rehabilitation program on pulmonary function, exercise performance, and quality of life in patients with severe COVID-19.

BACKGROUND: Severe coronavirus 2019 disease (COVID-19) causes acute hypoxemic respiratory failure requiring invasive mechanical ventilation (IMV). Once these symptoms are resolved, patients can present systemic deterioration. OBJECTIVE: The two objectives of this study were as follows: to describe the results of a pulmonary rehabilitation program (PRP), which is divided into three groups with different numbers of sessions (12, 24, and 36), and to associate the variables of pulmonary function, exercise performance, and functionality with the number of sessions and functional improvement. DESIGN: Prospective, observational study. METHODS: PRP consisted of aerobic + strength + flexibility exercises under the supervision and individualized into 12, 24, or 36 sessions (12s, 24s, and 36s), depending on the evolution of each patient. At the beginning of the study and immediately after the intervention, forced vital capacity (FVC), maximal inspiratory pressure, 6-minute walk test (6MWT), sit-to-stand test (STS), maximal handgrip strength (HGS), Fatigue Assessment Scale, Post-COVID-19 Functional Status (PCFS), and health-related quality of life (HRQoL) were measured. RESULTS: The proposed PRP demonstrated a positive effect on pulmonary function, exercise performance, and HRQoL, regardless of the number of sessions. A higher score on the PCFS and more days on IMV were associated with the increased likelihood of needing more sessions, whereas more meters on the 6MWT in the initial evaluation was associated with a reduced likelihood of needing more sessions. Finally, more repetitions on the STS and less distance covered on the initial 6MWT were associated with a greater improvement in exercise performance evaluated with the 6MWT. CONCLUSION: Supervised and individualized PRP for patients with severe post-COVID-19 improves pulmonary function, exercise performance, functionality, and quality of life. Functionality, distance covered on the 6MWT, and the days on IMV are central to the scheduling of the number of sessions for these patients.

Pulmonary Rehabilitation Associated with Noninvasive Ventilation on Physical Capacity and Quality of Life in Post-COVID-19: A Randomized Controlled Double-Blinded Clinical Trial Protocol.

Background: The coronavirus disease-2019 (COVID-19) pulmonary rehabilitation (PR) seems to be a better choice to improve physical and functional capacity after acute infection. However, there is a lack of evidence regarding the effects of different strategies to optimize post-acute phase rehabilitation and reduce long COVID-19 physical deteriorations. Objective: To compare the use of a noninvasive ventilation (NIV) plus aerobic exercise strategy during PR program with to a standard PR (without NIV) on physical capacity and quality of life outcomes in post-COVID-19. Methods: Double-blinded randomized controlled clinical trial. A total of 100 individuals discharged from hospital in a post-acute phase of severe COVID-19 will be randomized into two groups: PR + NIV (Group 1) and PR (Group 2). Inclusion criteria include participants who present symptomatic dyspnea II and III by the modified Medical Research Council, aged 18 years or older. Both groups will receive aerobic and resistance exercise, and inspiratory muscle training. However, group 1 will perform aerobic training with bilevel NIV. Cardiopulmonary exercise test will assess the O2 peak uptake, 6-minute walk test will assess the walking distance and short-form 36 will assess the quality of life before and after 8 weeks (after 24 PR sessions). Moreover, patients will be contacted by telephone every 3 months for one year to record possible adverse events, hospitalizations, and death. All data will be registered in RedCap, and analyses will be performed in the STATA v13 software. Clinical Trial Registration: RBR-3t9pkzt.

Aerobic physical training reduces severe asthma phenotype involving kinins pathway.

INTRODUCTION: Aerobic physical training (APT) reduces eosinophilic airway inflammation, but its effects and mechanisms in severe asthma remain unknown. METHODS: An in vitro study employing key cells involved in the pathogenesis of severe asthma, such as freshly isolated human eosinophils, neutrophils, and bronchial epithelial cell lineage (BEAS-2B) and lung fibroblasts (MRC-5 cells), was conducted. Additionally, an in vivo study using male C57Bl/6 mice, including Control (Co; n = 10), Trained (Exe; n = 10), house dust mite (HDM; n = 10), and HDM + Trained (HDM + Exe; n = 10) groups, was carried out, with APT performed at moderate intensity, 5x/week, for 4 weeks. RESULTS: HDM and bradykinin, either alone or in combination, induced hyperactivation in human neutrophils, eosinophils, BEAS-2B, and MRC-5 cells. In contrast, IL-10, the primary anti-inflammatory molecule released during APT, inhibited these inflammatory effects, as evidenced by the suppression of numerous cytokines and reduced mRNA expression of the B1 receptor and ACE-2. The in vivo study demonstrated that APT decreased bronchoalveolar lavage levels of bradykinin, IL-1ß, IL-4, IL-5, IL-17, IL-33, TNF-α, and IL-13, while increasing levels of IL-10, klotho, and IL-1RA. APT reduced the accumulation of polymorphonuclear cells, lymphocytes, and macrophages in the peribronchial space, as well as collagen fiber accumulation, epithelial thickness, and mucus accumulation. Furthermore, APT lowered the expression of the B1 receptor and ACE-2 in lung tissue and reduced bradykinin levels in the lung tissue homogenate compared to the HDM group. It also improved airway resistance, tissue resistance, and tissue damping. On a systemic level, APT reduced total leukocytes, eosinophils, neutrophils, basophils, lymphocytes, and monocytes in the blood, as well as plasma levels of IL-1ß, IL-4, IL-5, IL-17, TNF-α, and IL-33, while elevating the levels of IL-10 and IL-1RA. CONCLUSION: These findings indicate that APT inhibits the severe asthma phenotype by targeting kinin signaling.

Real-time telerehabilitation for chronic respiratory disease and post-COVID-19: A systematic review and meta-analysis.

INTRODUCTION: Telerehabilitation may facilitate access and adherence to pulmonary rehabilitation. Given the heterogeneity in existing telerehabilitation studies, it is still necessary to identify the most effective, safe, and cost-efficient strategy for clinical implementation, as well as the necessary level of supervision during telerehabilitation. The aim of this review was to determine the effectiveness and safety of real-time telerehabilitation for chronic respiratory diseases and post-COVID-19 compared to no-rehabilitation, center-based rehabilitation or asynchronous telerehabilitation. METHODS: A comprehensive search was conducted in six databases until 30 April 2023. Clinical trials of real-time telerehabilitation supervised via videoconference in adults with diagnosis of any chronic respiratory disease or post-COVID-19 were included. RESULTS: Twelve studies with 1540 participants were included. Very-low to moderate certainty evidence showed no difference between real-time telerehabilitation and center-based pulmonary rehabilitation. Studies included in this review reported high adherence rates to real-time telerehabilitation and completion rate, with no difference compared to center-based pulmonary rehabilitation. When compared to no-rehabilitation, the results of this review provide low-certainty evidence that real-time telerehabilitation may have a potential effect on exercise capacity at the end of the intervention, with no better results in others outcomes. No studies comparing real-time telerehabilitation with asynchronous telerehabilitation were found. CONCLUSION: Real-time telerehabilitation is safe and it seems to promote similar effects to center-based pulmonary rehabilitation. However, the certainty of this evidence ranged from very-low to moderate. Therefore, real-time telerehabilitation offers an alternative to center-based pulmonary rehabilitation models. This review provides a clear definition of real-time telerehabilitation, facilitating results interpretation and clinical applicability.

A pulmonary rehabilitation program is an effective strategy to improve forced vital capacity, muscle strength, and functional exercise capacity similarly in adults and older people with post-severe COVID-19 who required mechanical ventilation.

BACKGROUND: It is internationally known that our population is aging. At the same time, some patients with COVID-19, due to their symptoms, required mechanical ventilation (MV) and subsequent pulmonary rehabilitation (PR). This study aimed to compare the effects of a multimodal PR program "ADULT" versus "OLDER" people with COVID-19 who were on MV. METHODS: The intervention consisted of an 8-week hybrid PR program (2x week). Forced vital capacity (FVC) was measured at the beginning and end of PR, upper and lower limb strength was obtained through hand grip strength (HGS) and the sit-to-stand test (STST), respectively, and functional exercise capacity was measured with the 6-minute walking test (6MWT). RESULTS: The main results were an increase in the FVC in the ADULT and OLDER groups (time effect, P = 0.000; η2 = 0.27), an increase in HGS in the ADULT and OLDER groups (time effect, P = 0.000; η2 = 0.52), in the same way, the number of repetitions on the STST increased in the ADULT and OLDER groups (time effect, P = 0.000; η2 = 0.55). Finally, the distance covered on the 6MWT increased in the ADULT and OLDER groups (time effect, P = 0.000; η2 = 0.65). CONCLUSIONS: The PR program is an effective strategy to improve FVC, muscle strength, and functional exercise capacity similarly in adults and older people with post severe COVID-19 who required MV.

Efficacy of pulmonary telerehabilitation on exercise tolerance, fatigue, perceived exertion, depression, and quality of life in COVID-19 survivors / Eficácia da telereabilitação pulmonar na tolerância ao exercício, fadiga, percepção de esforço, depressão e qualidade de vida em sobreviventes de COVID-19

INTRODUCTION: Telerehabilitation advanced significantly with the emergence of COVID-19 and the recommendation of limiting physiotherapist-patient contact time whenever practicable. The effectiveness of telerehabilitation on those who had a longer stay in hospital and on oxygen support following discharge is still under question. OBJECTIVES: To evaluate the effects after six weeks of pulmonary telerehabilitation on exercise tolerance, fatigue level, perceived exertion, symptoms of depression and quality of life in patients surviving COVID-19. MATERIALS AND METHODS: A quasi-experimental study was conducted on 25 post-COVID-19 patients following discharge in a home environment setting. The participants were advised to prepare equipment such as oxygen concentrator, B-type oxygen cylinder (backup), lengthy oxygen tubes, finger pulse oximeter, mini static pedal exerciser, incentive spirometry, weight cuffs or water bottles and sandbags. After six weeks of telerehabilitation, the patients underwent assessments including initial oxygen saturation (SPO2), heart rate, peak oxygen demand during exercise to maintain baseline SPO2, peak heart rate, maximum drop in SPO2, recovery time to baseline SPO2 measured with a pulse oximeter and stopwatch, peak perceived exertion using the Borg Dyspnea Scale, peak fatigue score using the visual analog scale (VASF), quality of life assessed with the SF-36 questionnaire, and mental health status evaluated with the Hamilton Depression Scale (HAMD). One-way repeated measure ANOVA and paired t-test were used. RESULTS: Significant improvements following the intervention on the initial SPO2 (F (2.12, 23.13) = 21.0, p< 0.05) and quality of life also showed significant improvement (mean difference =29.92, p< 0.05). CONCLUSION: Six weeks of comprehensive pulmonary telerehabilitation with simple equipment improved tolerance to exercise, fatigue, perceived exertion, symptoms of depression and quality of life for post-COVID-19 patients.

INTRODUÇÃO: A telereabilitação avançou significativamente com o surgimento da COVID-19 e a recomendação de limitar o tempo de contato entre fisioterapeutas e pacientes sempre que possível. A eficácia da telereabilitação em pacientes que permaneceram mais tempo no hospital e necessitaram de suporte de oxigênio após a alta ainda está em questão. OBJETIVO: Para avaliar os efeitos após seis semanas de telereabilitação pulmonar na tolerância ao exercício, nível de fadiga, percepção de esforço, sintomas de depressão e qualidade de vida em pacientes sobreviventes de COVID-19. MATERIAIS E MÉTODOS: Foi realizado um estudo quase-experimental com dezesseis pacientes pós-COVID-19 selecionados de um hospital multispecializado. Os participantes foram orientados a preparar equipamentos como concentrador de oxigênio, cilindro de oxigênio tipo B (reserva), tubos de oxigênio longos, oxímetro de pulso, exercitador de pedal estático, espirômetro incentivador, pesos de tornozelo ou garrafas d'água e sacos de areia. Após seis semanas de telereabilitação, os pacientes foram submetidos a avaliações, incluindo saturação inicial de oxigênio (SPO2), frequência cardíaca, demanda máxima de oxigênio durante o exercício para manter a SPO2 basal, frequência cardíaca máxima, queda máxima na SPO2, tempo de recuperação para SPO2 basal medido com um oxímetro de pulso e cronômetro, esforço percebido máximo usando a Escala de Dispneia de Borg, pontuação máxima de fadiga usando a escala analógica visual (VASF), qualidade de vida avaliada com o questionário SF-36 e estado de saúde mental avaliado com a Escala de Depressão de Hamilton (HAMD). RESULTADOS: Melhorias significativas após a intervenção foram observadas na SPO2 inicial (F (2,12, 23,13) = 21,0, p <0,05) e na frequência cardíaca (F (1,839, 20,23) = 43,73, p <0,05), demanda máxima de oxigênio durante o exercício para manter a SPO2 basal (F (1,487, 16,36) = 8,96, p <0,05), esforço percebido máximo (F (5, 55) = 112,51, p <0,05), pontuação máxima de fadiga (F (1,755, 19,30) = 67,44, p <0,05), frequência cardíaca máxima (F (1,798, 19,78) = 50,99, p <0,05), queda máxima na SPO2 (F (2,467, 27,14) = 41,46, p <0,05) e tempo máximo de recuperação para alcançar a SPO2 basal (F (5, 55) = 78,89, p <0,05). A análise de seis semanas pós-intervenção nos sintomas depressivos (diferença média = 11,25, p <0,05) e na qualidade de vida também mostrou melhoria significativa (diferença média = 29,92, p <0,05). CONCLUSÃO: Seis semanas de telereabilitação pulmonar abrangente com equipamentos simples melhoraram a tolerância ao exercício, a fadiga, a percepção de esforço, os sintomas de depressão e a qualidade de vida em pacientes pós-COVID-19.

Hospitalisations and fatality due to respiratory diseases according to a national database in Brazil: a longitudinal study.

BACKGROUND: Respiratory diseases (RDs) cause millions of hospitalisations and deaths worldwide, resulting in economic and social impacts. Strategies for health promotion and disease prevention based on the epidemiological profile of the population may reduce hospital costs. AIM: To characterise hospitalisations and deaths due to RDs in Brazilian adults above 20 years old between 2008 and 2021. METHODS: This ecological study used secondary data of hospitalisations and deaths due to RDs from the Hospital Information System of the Brazilian Unified Health System between 2008 and 2021. Data were grouped according to region, age group and sex. The period was divided into first (2008-2011), second (2012-2015) and third (2016-2019) quadrennia and one biennium (2020-2021), and all data were analysed using the GraphPad Prism; statistical significance was set at p<0.05. RESULTS: A total of 9 502 378 hospitalisations due to RDs were registered between 2008 and 2021. The south and southeast regions presented the highest hospitalisation and fatality rate, respectively, in the age group ≥80 years with no significant differences between sexes. Also, RDs caused 1 170 504 deaths, with a national fatality rate of 12.32%. CONCLUSION: RDs affected the Brazilian population and impaired the health system, especially the hospital environment. The south/southeast regions were the most affected, and the ageing process contributed to the increased incidence of RDs.

Systemic Inflammation but not Oxidative Stress Is Associated with Physical Performance in Moderate Chronic Obstructive Pulmonary Disease.

Chronic obstructive pulmonary disease (COPD) patients manifest muscle dysfunction and impaired muscle oxidative capacity, which result in reduced exercise capacity and poor health status. The aim of this study was to compare the physical performance, systemic inflammation, and oxidative stress of patients with moderate COPD, and to associate physical performance with inflammatory and oxidative stress plasma markers. Twenty CONTROL (n = 10) and moderate COPD (n = 10) patients participated in this study. Systematic inflammation and oxidative stress plasma markers, maximal aerobic capacity (VO2peak), and maximal isometric strength (MVIC) of the knee extensor (KE) muscles were measured. VO2peak was 31.3% greater in CONTROL compared to COPD (P = 0.006). The MVIC strength of the KE was 43.9% greater in CONTROL compared to COPD (P = 0.002). Tumor necrosis factor-alpha (TNF-α) was 79.6% greater in COPD compared to CONTROL (P < 0.001). Glutathione peroxidase activity (GPx) activity was 27.5% lesser in COPD compared to CONTROL (P = 0.05). TNF-α concentration was correlated with KE MVC strength (R = -0.48; P = 0.045) and VO2peak (R = -0.58; P = 0.01). Meanwhile, malondialdehyde (MDA) and GPx activity were not associated with KE strength or VO2peak (P = 0.74 and P = 0.14, respectively). COPD patients showed lesser muscle strength and aerobic capacity than healthy control individuals. Furthermore, patients with COPD showed greater systemic inflammation and lesser antioxidant capacity than healthy counterparts. A moderate association was evident between levels of systemic inflammation and physical performance variables.

Effects of transcutaneous electrical diaphragmatic stimulation in critically ill elderly patients: a randomized controlled trial.

BACKGROUND: Elderly patients under invasive mechanical ventilation (IMV) are more susceptible to muscle weakness. In the out-of-hospital environment, there are benefits to transcutaneous electrical diaphragmatic stimulation (TEDS), which is an easy-to-apply and low-cost technique. OBJECTIVE: To evaluate the effect of TEDS on respiratory muscle strength, diaphragm thickness (DT), and IMV time in critically ill elderly patients. METHODS: This was a randomized controlled trial in which patients were divided into an experimental group (EG) and a control group (CG). TEDS started 24 h after orotracheal intubation and lasted until the end of weaning. Both groups underwent the following assessments during the spontaneous breathing test after weaning from mechanical ventilation (MV): measurement of respiratory muscle strength by pressure gauge, analysis of DT by lung ultrasound, and extubation failure prevention checklist. RESULTS: There were 23 participants in the EG and 21 in the CG. The median age was 66 (60-79) years. The mean values of the diaphragmatic thickening index in the EG and CG participants were 99.13 ± 26.75 and 66.88 ± 31.77, respectively (p = .001, Cohen's d = 1.094). The mean values of maximum inspiratory pressure in the EG and CG were 22.04 ± 3.41 and 19.34 ± 4.23 cmH2O, respectively (p = .005, Cohen's d = 0.698). The Tobin index and the integrative weaning index were similar between groups (p = .584 and p = .102, respectively). The duration of MV in the EG and CG was 6.28 ± 2.68 and 9.21 ± 2.76 days, respectively (p = .001, Cohen's d = -1.075). CONCLUSION: Critically ill elderly patients receiving TEDS had shorter MV time, greater inspiratory muscle strength, and greater diaphragmatic contraction capacity according to their thickness fraction.

Unmet Diagnostic and Therapeutic Opportunities for Chronic Obstructive Pulmonary Disease in Low- and Middle-Income Countries.

Rationale: Chronic obstructive pulmonary disease (COPD) is a prevalent and burdensome condition in low- and middle-income countries (LMICs). Challenges to better care include more effective diagnosis and access to affordable interventions. There are no previous reports describing therapeutic needs of populations with COPD in LMICs who were identified through screening. Objectives: To describe unmet therapeutic need in screening-detected COPD in LMIC settings. Methods: We compared interventions recommended by the international Global Initiative for Chronic Obstructive Lung Disease COPD strategy document, with that received in 1,000 people with COPD identified by population screening at three LMIC sites in Nepal, Peru, and Uganda. We calculated costs using data on the availability and affordability of medicines. Measurement and Main Results: The greatest unmet need for nonpharmacological interventions was for education and vaccinations (applicable to all), pulmonary rehabilitation (49%), smoking cessation (30%), and advice on biomass smoke exposure (26%). Ninety-five percent of the cases were previously undiagnosed, and few were receiving therapy (4.5% had short-acting ß-agonists). Only three of 47 people (6%) with a previous COPD diagnosis had access to drugs consistent with recommendations. None of those with more severe COPD were accessing appropriate maintenance inhalers. Even when available, maintenance treatments were unaffordable, with 30 days of treatment costing more than a low-skilled worker's daily average wage. Conclusions: We found a significant missed opportunity to reduce the burden of COPD in LMIC settings, with most cases undiagnosed. Although there is unmet need in developing novel therapies, in LMICs where the burden is greatest, better diagnosis combined with access to affordable interventions could translate to immediate benefit.

Effectiveness and Safety of Multicomponent Physical Training in Patients With Chronic Obstructive Pulmonary Disease: Protocol for a Randomized Clinical Trial.

Background: Currently, most Pulmonary Rehabilitation (PR) programs work with conventional physical training, using resources that are not available in public health in Brazil. Multicomponent physical training is a strategy that uses few resources and can reach a larger portion of the population. Objective: To investigate the effectiveness and safety of multicomponent physical training on physical-functional performance in patients with COPD. Design: Protocol for a randomized clinical trial with 2 groups in parallel (1:1). Setting: University-based, outpatient, physiotherapy clinic. Participants: 64 patients aged ⩾50 years, clinical-functional diagnosis of COPD, GOLD II and III criteria will participate in the study. Intervention: Participants will be randomly allocated into 2 groups: Multicomponent Physical Training-MPT (n = 32): aerobic, strength, balance and flexibility exercises performed in a circuit training format, or Conventional Physical Training-CPT (n = 32): aerobic and strength training. The interventions will be carried out twice a week, for 8 weeks and supervised by the same physiotherapist. Measurements: The 3 primary outcomes are the 6-Minute Walk Test (6MWT), the 6-Minute Step Test (6MST) and VO2 consumption as measured during the 6MWT. Secondary outcomes will be exercise capacity, level of physical activity in daily life, peripheral muscle strength, functional status, dyspnea, fatigue and quality of life. Safety will be assessed by recording adverse effects. These outcomes will be evaluated before and after the intervention and the evaluator will be blind. Limitations: It will not be possible to perform the blinding of the physiotherapist who will supervise the interventions. Conclusions: This study is expected to demonstrate that MPT using simple resources is an effective and safe intervention for the improvement of the aforementioned outcomes and, in addition, to broaden the horizon of research in relation to new methods of physical rehabilitation for patients with COPD.

Use of the speed achieved on the 6MWT for programming aerobic training in patients recovering from severe COVID-19: an observational study.

INTRODUCTION: Patients who suffered severe COVID-19 need pulmonary rehabilitation. Training may be prescribed objectively based on the maximum speed in the six-minute walk test. The objective of this study was to determine the effects of a personalized pulmonary rehabilitation program based on the six-minute walk test speed for post-COVID-19 patients. METHODS: Observational quasi-experimental study. The pulmonary rehabilitation program consisted of 8 weeks of training, twice a week for 60 minutes per session of supervised exercise. Additionally, the patients carried out home respiratory training. Patients were evaluated by exercise test, spirometry and the Fatigue Assessment Scale before and after the eight-week pulmonary rehabilitation program. RESULTS: After the pulmonary rehabilitation program, forced vital capacity increased from 2.47 ± 0.60 to 3.06 ± 0.77 L (p < .001) and the six-minute walk test result increased from 363.50 ± 88.87 to 480.9 ± 59.25 m (p < .001). In fatigue perception, a significant decrease was observed, from 24.92 ± 7.01 to 19.10 ± 7.07 points (p < .01). Isotime evaluation of the Incremental Test and the Continuous Test showed a significant reduction in heart rate, dyspnoea and fatigue. CONCLUSION: The eight-week personalized pulmonary rehabilitation program prescribed on the basis of the six-minute walk test speed improved respiratory function, fatigue perception and the six-minute walk test result in post-COVID-19 patients.KEY MESSAGESCOVID-19 is a multisystem disease with common complications affecting the respiratory, cardiac and musculoskeletal systems.The 6MWT speed-based training plan allowed for increased speed and incline during the eight-week RP program.Aerobic, strength and flexibility training reduced HR, dyspnoea and fatigue in severe post-COVID-19 patients.

Changes in Blood Markers of Oxidative Stress, Inflammation and Cardiometabolic Patients with COPD after Eccentric and Concentric Cycling Training.

Chronic obstructive pulmonary disease (COPD) patients manifest muscle dysfunction and impaired muscle oxidative capacity, which result in reduced exercise capacity and poor health status. This study examined the effects of 12-week eccentric (ECC) and concentric (CONC) cycling training on plasma markers of cardiometabolic health, oxidative stress, and inflammation in COPD patients. A randomized trial in which moderate COPD was allocated to ECC (n = 10; 68.2 ± 10.0 year) or CONC (n = 10; 71.1 ± 10.3 year) training groups. Participants performed 12-week ECC or CONC training, 2-3 sessions per week, 10 to 30 min per session. Before and after training, peak oxygen consumption, maximal power output (VO2peak and POmax), and time-to-exhaustion (TTE) tests were performed. Plasma antioxidant and oxidative markers, insulin resistance, lipid profile, and systemic inflammation markers were measured before and after training at rest. VO2peak, POmax and TTE remained unchanged after ECC and CONC. CONC induced an increase in antioxidants (p = 0.01), while ECC decreased antioxidant (p = 0.02) markers measured at rest. CONC induced lesser increase in oxidative stress following TTE (p = 0.04), and a decrease in insulin resistance (p = 0.0006) compared to baseline. These results suggest that CONC training induced an increase in insulin sensitivity, antioxidant capacity at rest, and lesser exercise-induced oxidative stress in patients with moderate COPD.

Availability and characteristics of pulmonary rehabilitation programs in family health centers and hospitals from Chile: Descriptive, retrospective and multicentric study.

OBJECTIVE: To determine availability and characteristics of pulmonary rehabilitation programs performed in 2019 in family health centers and hospitals from Chile. METHODOLOGY: A descriptive and retrospective study was designed, considering PR programs operated in 2019. A non-probability and convenience sample was obtained. Availability and characteristics of centers and PR were measured using a questionnaire translated, modified, validated, and sent by email. RESULTS: Out of 80 responses (22.8%), 60% of centers offered PR program, where the lack of time was the greatest barrier. The programs were mainly outpatient, non-personalized, with 10(IQR 4-11) participants, 12 (IQR 12-16) weeks of length, with 2.4 ± 0.6 session/week, and 1 (IQR 1-2) hours/session. Chronic Obstructive Pulmonary Disease (COPD) was the most frequent diagnostic. The programs were mainly comprised of strength training exercises of lower extremity, upper extremity, walking and education. Team was constituted of physiotherapist and physician, with completed training, and directed by a physiotherapist. Modified Borg, MRC dyspnea scale, six-minute walking test and oximetry were used in the assessments. Between 40-80% of patients completed PR, and the major barrier was patient relocated. CONCLUSION: Increasing PR availability, homogenization of exercises and education, prioritization of assessments supported by scientific evidence, and inclusion of follow-up could be useful to improve the access, quality and results of the treatment, considering new models of PR that allow greater access and acceptability.

Physical, Functional, Psychological, and Social Effects of a Physical Activity Program in Adults and Older Adults During and/or After Hospitalization for COVID-19: A Systematic Review.

Background: It is necessary to investigate the effects of physical activity (PA) on the recovery of adults and the elderly, considering PA positively affects pathologies that share similarities with COVID-19. We present the results of a systematic review whose objective was to analyze the physical, functional, psychological, and social effects of PA in adults and the elderly during and/or after hospitalization for COVID-19. Methods: Searches were conducted between July and August 2021, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Randomized clinical trials (RCTs) and non-randomized interventional studies were included in the databases: PubMed, Web of Science, Scopus, EBSCOhost, Science Direct, Cochrane Library, Physiotherapy Evidence Database (PEDro), and electronic search engines. Study quality was assessed using the PEDro for RCTs and the methodological index scale for non-randomized studies. This systematic review included original articles investigating the physical, functional, psychological, and social effects of any PA program on adults and older adults. Results: A total of 302 studies were found. After applying filters according to the eligibility criteria, five studies were finally included for analysis, three RCTs and two intervention studies without a control group. Although the studies measured different variables of the physical, functional, and psychological components, the results showed significant differences in the variables between the control and intervention groups in both the RCTs and the single-group studies. The variables assessed in the social aspect were less homogeneous. Conclusion: In the available scientific evidence, respiratory muscle training was the most widely used intervention, which showed positive results in the physical, pulmonary, psychological, and social components. More research is required on the effects of PA on the population studied.

A Telerehabilitation Program for Maintaining Functional Capacity in Patients With Chronic Lung Diseases During a Period of COVID-19 Social Isolation: Quasi-Experimental Retrospective Study.

BACKGROUND: Pulmonary diseases represent a great cause of disability and mortality in the world, and given the progression of these pathologies, pulmonary rehabilitation programs have proven to be effective for people with chronic respiratory diseases. During the COVID-19 pandemic, telerehabilitation has become an alternative for patients with such diseases. OBJECTIVE: The aim of this study was to compare the outcomes (ie, functional capacity and quality of life) of telerehabilitation to those of usual care among patients who previously participated in face-to-face pulmonary rehabilitation programs. METHODS: We conducted a quasi-experimental retrospective study from April 2020 to August 2021. A total of 32 patients with chronic lung diseases were included and divided into the control and intervention groups. The intervention group performed telerehabilitation synchronously twice per week and was supervised by a physical therapist during breathing, strengthening, and aerobic exercises. Changes in the degree of dyspnea and leg discomfort were assessed based on changes in Borg scale scores. The control group did not perform any activities during the period of social isolation. Functional capacity was assessed with the 6-minute walk test, and quality of life was assessed with the Medical Outcomes Study 36-item Short Form Health Survey. RESULTS: The telerehabilitation group's mean 6-minute walk distance decreased by 39 m, while that of the control group decreased by 120 m. There was a difference of 81 m between the groups' mean 6-minute walk distances (P=.02). In relation to the quality of life, telerehabilitation was shown to improve the following two domains: social functioning and mental health. CONCLUSIONS: Telerehabilitation programs for patients with chronic lung diseases can ease the deleterious effects of disease progression, be used to maintain functional capacity, and improve aspects of quality of life.

Pulmonary and Functional Rehabilitation Improves Functional Capacity, Pulmonary Function and Respiratory Muscle Strength in Post COVID-19 Patients: Pilot Clinical Trial.

BACKGROUND: Patients affected by COVID-19 may develop an impaired lung function, with reduced lung capacities and volumes, respiratory muscle weakness, changes in radiographic and tomographic findings, limitations in exercising, decreased functional capacity, depression, anxiety and reduced quality of life. Thus, we aimed to analyze the effects of a pulmonary and functional rehabilitation program on the functional capacity, lung function and respiratory muscle strength in patients who were affected by COVID-19 syndrome. METHODS: This is a pilot clinical trial, composed of post-COVID-19 patients with mild, moderate or severe involvement, in which, they underwent a pulmonary and functional rehabilitation program. Patients were evaluated for functional capacity by the 6 min walk test, pulmonary function by spirometry, respiratory muscle strength by manovacuometry, handgrip strength by dynamometry, quality of life by the COPD Assessment Test and functional status by the PCFS. After the initial assessments, the patients performed the rehabilitation protocol in 16 sessions (inspiratory muscle training, aerobic exercise and peripheral muscle strength) and, at the end, they were evaluated again. RESULTS: A total of 29 patients completed the program (12.7 ± 2.7 sessions). The functional capacity increased in meters walked from 326.3 ± 140.6 to 445.4 ± 151.1 (p < 0.001), with an increase in the predicted value from 59.7% to 82.6% (p < 0.001). The lung function increased in liters from 2.9 ± 0.8 to 3.2 ± 0.8 (p = 0.004) for forced vital capacity and from 2.5 ± 0.7 to 2.7 ± 0.7 (p = 0.001) for forced expiratory volume in the first second. The respiratory muscle strength increased in cmH2O from 101.4 ± 46.3 to 115.8 ± 38.3 (p = 0.117) for inspiratory pressure and from 85.8 ± 32.8 to 106.7 ± 36.8 (p < 0.001) for expiratory pressure. CONCLUSIONS: The pulmonary and functional rehabilitation program provided an improvement in the functional capacity, pulmonary function and respiratory muscle strength in post-COVID-19 patients, restoring their quality of life.

Embedding Pulmonary Rehabilitation for Chronic Obstructive Pulmonary Disease in the Home and Community Setting: A Rapid Review.

This paper presents a rapid review of the literature for the components, benefits, barriers, and facilitators of pulmonary rehabilitation for chronic obstructive pulmonary disease (COPD) people in-home and community-based settings. seventy-six studies were included: 57 home-based pulmonary rehabilitation (HBPR) studies and 19 community-based pulmonary rehabilitation (CBPR) studies. The benefits of HBPR on exercise capacity and health-related quality of life were observed in one-group studies, studies comparing HBPR to usual care, and studies comparing to hospital-based pulmonary rehabilitation, although the benefits were less pronounced in the latter. HBPR reduced hospital admissions compared to usual care and was more cost-effective than hospital pulmonary rehabilitation. Most HBPRs were designed with low-density or customized equipment, are minimally supervised, and have a low intensity of training. Although the HBPR has flexibility and no travel burden, participants with severe disease, physical frailty, and complex comorbidities had barriers to complying with HBPR. The telerehabilitation program, a facilitator for HBPR, is feasible and safe. CBPR was offered in-person supervision, despite being limited to physical therapists in most studies. Benefits in exercise capacity were shown in almost all studies, but the improvement in health-related quality of life was controversial. Patients reported the benefits that facilities where they attended the CBPR including social support and the presence of an instructor. They also reported barriers, such as poor physical condition, transport difficulties, and family commitments. Despite the minimal infrastructure offered, HBPR and CBPR are feasible, safe, and provide clinical benefits to patients with COPD. Home and community settings are excellent opportunities to expand the offer of pulmonary rehabilitation programs, as long as they follow protocols that ensure quality and safety following current guidelines.

Home-Based Respiratory Physiotherapy and Telephone-Based Psychological Support for COVID-19 Survivors in Peru: Protocol for a Randomized Controlled Trial.

BACKGROUND: Both pulmonary and mental health are affected following hospitalization for COVID-19 pneumonia. Pulmonary rehabilitation therapy has demonstrated benefits in improving mental health, but no validated combined programs that include mental health have been proposed. OBJECTIVE: This article presents the design of a trial that aimed to assess whether the participation in a combined rehabilitation program that includes home-based respiratory physiotherapy and telephone-based psychological support is associated with a greater improvement of pulmonary and mental health outcomes 7-12 weeks after COVID-19 hospitalization discharge compared with posthospital usual care provided by a public Peruvian hospital. METHODS: WAYRA (the word for air in the Quechua language) was an open-label, unblinded, two-arm randomized controlled trial. We recruited 108 participants aged 18-75 years who were discharged from the hospital after COVID-19 pneumonia that required >6 liters/minute of supplemental oxygen during treatment. Participants were randomly assigned at a 1:1 ratio to receive the combined rehabilitation program or usual posthospital care provided by a public Peruvian hospital. The intervention consisted of 12 at-home respiratory rehabilitation sessions and 6 telephone-based psychological sessions. The primary outcome was the 6-minute walk distance. Secondary outcomes included lung function, mental health status (depression, anxiety, and trauma), and quality of life. Outcomes were assessed at baseline (before randomization) and at 7 and 12 weeks after hospital discharge to assess the difference between arms. RESULTS: This study was funded by the Peruvian National Council of Science Technology and Technology Innovation in July 2020. Ethics approval was obtained on September 2, 2020. Recruitment and data collection occurred between October 2020 and June 2021. Results are expected to be published by the end of 2022. CONCLUSIONS: WAYRA was the first randomized controlled trial evaluating combined pulmonary-mental health rehabilitation for hospitalized COVID-19 survivors in resource-limited settings, potentially providing a foundation for the cost-effective scale-up of similar multidisciplinary rehabilitation programs.
