Effect of Meditation and Breathing Exercises on the Well-being of Patients with SARS-CoV-2 Infection under Institutional Isolation: A Randomized Control Trial

Efficacy of exercise treatments for chronic obstructive pulmonary disease: A systematic review

OBJECTIVE

To review the efficacy of exercise treatments on chronic obstructive pulmonary disease (COPD).

DATA SOURCES

PubMed, Scopus, Science Direct, Ebscohost, SPORTDiscus, ProQuest, Web of Science.

REVIEW METHODS

A systematic review was performed to identify the relevant studies published from 2011 to 2023. Studies were selected using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 5170 articles were retrieved and assessed using the Physiotherapy Evidence Database (PEDro) scale. The risk of bias in individual studies was assessed with the Cochrane risk of bias tool.

RESULTS

A total of 38 eligible studies were included. Eight studies evaluated the effects of Tai Chi, followed by Liuzijue (five studies) and yoga (three studies). The duration of the exercise programmes ranged from 8 weeks to 3 years, and the frequency was between 2 and 7 times a week. Exercise sessions lasted between 20 and 90 min. Low-intensity exercise improved lung function after six months. Whole-body exercise improved dyspnea more than local exercise. Water-based exercise improved physical endurance more than land exercise, and quality of life was unaffected by long-term exercise.

CONCLUSION

This systematic review highlights the benefit of exercise treatments as a potential adjunct treatment for COPD patients.

Effect of Yoga-based breathing practices on depression, anxiety, stress, and fear of COVID-19 positive hospitalized patients: A randomized controlled trial

BACKGROUND

COVID-19 infection has an impact on the mental state of patients and requires attention to mental health care.

OBJECTIVE

The aim of this study is to assess the effect of Yoga-based breathing practices on the mental state of patients with COVID-19.

MATERIAL AND METHODS

A randomized controlled trial was conducted with63 patients (male=46) who were RT-PCR positive for COVID-19 and hospitalized with asymptomatic (RT-PCR positive but no symptoms), mild (febrile, body ache, pharyngitis, nonproductive cough), and moderate (SpO2< 92%) symptoms assigned in the yoga (n=32) and control group (n=31). The study was conducted at Atharva Multispecialty Hospital and Research Center, North India. The yoga group received Yoga-based breathing practices twice a day for ten days in addition to conventional care, and the control group was advised not to do the practice. The Depression Anxiety and Stress scale (DASS-21) and fear of COVID-19 were assessed at baseline and after 10 days. Repeated measures ANOVA with Bonferroni correction was used to assess between and within subjects' effects.

RESULTS

The experimental group had better scores for depression, anxiety, stress, total DASS scores, and fear of COVID-19 (p<0.001) when compared with the control group. Within the group, analyses demonstrated improved scores in all domains in the yoga group (p<0.001) by the end of the intervention. In contrast, the control group improved only in stress scores (p=0.002), total DASS scores (p=0.012), and fear of COVID-19 (p=0.039). There are no adverse effects seen with Yoga-based breathing practices in these patients.

CONCLUSION

Yoga-based breathing practices have been found to have positive impact on mental health among COVID-19-positive patients during hospitalization.

Guiding future research on psychological interventions in people with COVID-19 and post COVID syndrome and comorbid emotional disorders based on a systematic review

Objective

The COVID-19 pandemic has been emotionally challenging for the entire population and especially for people who contracted the illness. This systematic review summarizes psychological interventions implemented in COVID-19 and long COVID-19 patients who presented comorbid emotional disorders.

Methods and measures

3,839 articles were identified in 6 databases and 43 of them were included in this work. Two independent researchers selected the articles and assessed their quality.

Results

2,359 adults were included in this review. Severity of COVID-19 symptoms ranged from asymptomatic to hospitalized patients; only 3 studies included long COVID-19 populations. Similar number of randomized controlled studies (n = 15) and case studies (n = 14) were found. Emotional disorders were anxiety and/or depressive symptoms (n = 39) and the psychological intervention most represented had a cognitive behavioral approach (n = 10). Length of psychological programs ranged from 1-5 sessions (n = 6) to 16 appointments (n = 2). Some programs were distributed on a daily (n = 4) or weekly basis (n = 2), but other proposed several sessions a week (n = 4). Short (5-10 min, n = 4) and long sessions (60-90 min, n = 3) are proposed. Most interventions were supported by the use of technologies (n = 18). Important risk of bias was present in several studies.

Conclusion

Promising results in the reduction of depressive, anxiety and related disorders have been found. However, important limitations in current psychological interventions were detected (i.e., duration, format, length, and efficacy of interventions were not consistently established across investigations). The results derived from our work may help to understand clinical practices in the context of pandemics and could guide future efforts to manage emotional suffering in COVID-19 patients. A stepped model of care could help to determine the dosage, length and format of delivery for each patient.Systematic review registration: PROSPERO 2022 CRD42022367227.

Rehabilitation and COVID-19: systematic review by Cochrane Rehabilitation

INTRODUCTION

Until the last update in February 2022, the Cochrane Rehabilitation COVID-19 Evidence-based Response (REH-COVER) action identified an increasing volume of evidence for the rehabilitation management of COVID-19. Therefore, our aim was to identify the best available evidence on the effectiveness of interventions for rehabilitation for COVID-19-related limitations of functioning of rehabilitation interest in adults with COVID-19 or post COVID-19 condition (PCC).

EVIDENCE ACQUISITION

We ran the searches on February 17th, 2023, in the following databases: PubMed, EMBASE, CENTRAL, CINHAL, and the Cochrane COVID-19 Study Register, applying a publication date restriction to retrieve only papers published in 2022. To retrieve papers published before 2022, we screened the reference lists of previous publications included in the REH-COVER action, covering papers from early 2020 to the end of 2022. This current review includes only randomised controlled trials and concludes the rapid living systematic reviews of the Cochrane Rehabilitation REH-COVER action. The risk of bias and certainty of evidence were evaluated in all studies using the Cochrane Risk of Bias tool and GRADE, respectively. We conducted a narrative synthesis of the evidence. PROSPERO registration number: CRD42022374244.

EVIDENCE SYNTHESIS

After duplicate removal, we identified 18,950 individual records and 53 RCTs met the inclusion criteria. Our findings suggest that the effect of breathing and strengthening exercise programs on dyspnea and physical exercise capacity compared to no treatment in non-severe COVID-19 patients is uncertain. Multicomponent telerehabilitation may slightly increase physical exercise capacity compared to educational intervention in adults with PCC. There is, however, uncertainty about its effect on lung function and physical exercise capacity when compared to no treatment. Finally, the effect of inspiratory muscle training on maximal inspiratory pressure compared to no treatment in adults with PCC is uncertain.

CONCLUSIONS

Interventions that are part of comprehensive pulmonary rehabilitation approaches may benefit dyspnea and exercise tolerance in adults with COVID-19 and PCC. The available evidence has several methodological limitations that limit the certainty of evidence and the clinical relevance of findings. Therefore, we cannot provide robust suggestions for practice. While high-quality RCTs are being conducted, clinicians should consider using high-quality evidence from other pulmonary conditions to rehabilitate patients with COVID-19 or PCC using context-specific interventions.

Evidence-based position paper on physical and rehabilitation medicine professional practice for persons with COVID-19, including post COVID-19 condition: the European PRM position (UEMS PRM Section)

Although multiple factors still pose challenges to inpatient/outpatient rehabilitation for survivors of COVID-19, rehabilitation plays a key role for this patient population. This study aimed to improve Physical and Rehabilitation Medicine (PRM) physician's professional practice for persons with COVID-19-related functioning limitations, to promote functional recovery and reduce activity limitations and/or participation restrictions. A systematic review of the scientific literature was performed from December 2019 to August 2022, followed by production of recommendations through 5 Delphi rounds, by consensus among the delegates of all European countries represented in the Union of European Medical Specialists PRM Section. The systematic literature review is reported together with thirty-two recommendations resulting from the Delphi procedure. The PRM physician's role for persons with COVID-19-related limitations of functioning is to develop, foster, and monitor the implementation of an individual rehabilitation project tailored to the patient's age, previous medical and functional status, current comorbidities and complications, activity limitations and participation restrictions and personal and environmental factors. This is done by applying the concept of a multi-specialty integrated service model with multi-professional/interdisciplinary teams, providing care at all stages of COVID-19 illness. This evidence-based position paper represents the official position of the European Union through the UEMS PRM Section.

Yoga for COVID-19: An ancient practice for a new condition - A literature review

A substantial proportion of people with acute COVID-19 develop post-COVID-19 condition (previously known as long-COVID) characterized by symptoms that persist for months after the initial infection, including neuropsychological sequelae. Post-COVID-19 condition frequency varies greatly according to different studies, with values ranging from 4 to 80% of the COVID-19 patients. Yoga is a psycho-somatic approach that increases physical, mental, emotional and spiritual strength, and connection. Yoga practice enhances innate immunity and mental health, so it can be used as complementary therapy in the COVID-19 treatment, namely the post-COVID-19 condition. In this article, we conducted a literature review on yoga and COVID-19, finding that an intervention comprising asana, pranayama, and meditation may be a strategy of choice for these patients' recovery. However, further studies are needed to show its effectiveness in this, still unknown, context.

Effect of breathwork on stress and mental health: A meta-analysis of randomised-controlled trials

Deliberate control of the breath (breathwork) has recently received an unprecedented surge in public interest and breathing techniques have therapeutic potential to improve mental health. Our meta-analysis primarily aimed to evaluate the efficacy of breathwork through examining whether, and to what extent, breathwork interventions were associated with lower levels of self-reported/subjective stress compared to non-breathwork controls. We searched PsycInfo, PubMed, ProQuest, Scopus, Web of Science, ClinicalTrials.gov and ISRCTN up to February 2022, initially identifying 1325 results. The primary outcome self-reported/subjective stress included 12 randomised-controlled trials (k = 12) with a total of 785 adult participants. Most studies were deemed as being at moderate risk of bias. The random-effects analysis yielded a significant small-to-medium mean effect size, g = - 0.35 [95% CI - 0.55, - 0.14], z = 3.32, p = 0.0009, showing breathwork was associated with lower levels of stress than control conditions. Heterogeneity was intermediate and approaching significance, χ²₁₁ = 19, p = 0.06, I² = 42%. Meta-analyses for secondary outcomes of self-reported/subjective anxiety (k = 20) and depressive symptoms (k = 18) showed similar significant effect sizes: g = - 0.32, p < 0.0001, and g = - 0.40, p < 0.0001, respectively. Heterogeneity was moderate and significant for both. Overall, results showed that breathwork may be effective for improving stress and mental health. However, we urge caution and advocate for nuanced research approaches with low risk-of-bias study designs to avoid a miscalibration between hype and evidence.

Mindfulness Meditation Interventions for Long COVID: Biobehavioral Gene Expression and Neuroimmune Functioning

Some individuals infected with SARS CoV-2 have developed Post-Acute Sequelae of SARS CoV-2 infection (PASC) or what has been referred to as Long COVID. Efforts are underway to find effective treatment strategies for those with Long COVID. One possible approach involves alternative medical interventions, which have been widely used to treat and manage symptoms of a variety of medical problems including post-viral infections. Meditation has been found to reduce fatigue and unrefreshing sleep, and for those with post-viral infections, it has enhanced immunity, and reduced inflammatory-driven pathogenesis. Our article summarizes the literature on what is known about mindfulness meditation interventions, and reviews evidence on how it may apply to those with Long COVID and Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Evidence is reviewed suggesting effective and sustainable outcomes may be achieved for symptomatology and underlying pathology of post-viral fatigue (PASC and ME/CFS).

[Welche Behandlungs-Optionen wurden von COVID-19 infizierten Yoga-Übenden als hilfreich empfunden? - Ergebnisse einer Querschnittsanalyse]

Einführung: Die meisten COVID-19 Infizierten machen die Infektion im häuslichen Umfeld durch und werden vermutliche Maßnahmen zur Symptomlinderung anwenden, die aus dem Bereich der Selbstverordnung kommen. Von Interesse ist daher, welche Maßnahmen von COVID-19 Infizierten genutzt werden. Methoden: Anonyme Querschnittsanalyse, bei der die eigenen Behandlungsoptionen in Bezug zu acht Hauptsymptomen mit Hilfe von Freitextfeldern erfasst und kategorisiert werden. Einbezogen wurden Datensätze von Yoga-Übenden als spezifische Zielgruppe, die sich in den Zeiträumen der drei dominanten Virus-Varianten infiziert hatten (n=208: 89% Frauen; Altersmittel 49 ± 11). Die Aussagen wurden deskriptiv dargestellt und die Inhalte der Freitextfelder nach inhaltsanalytischen Gesichtspunkten kategorisiert und den jeweiligen Hauptsymptomen einer COVID-19 Infektion zugeordnet. Ergebnisse: In Bezug auf die acht Symptomgruppen ergab sich ein differenziertes Bild der als hilfreich empfundenen Behandlungsoptionen. Die meisten Nennungen hatte die Kategorie Zeit/Ruhe/Schlaf, insbesondere bei Schwäche/Erschöpfung und Rumpf-/Gliederschmerzen, gefolgt von Atemübungen (Pranayama), die insbesondere bei Atemnot/Kurzatmigkeit und Husten zur Anwendung kamen. Yoga-Übungen wurden insbesondere bei Rumpf-/Gliederschmerzen sowie Schwäche/Erschöpfung genutzt. Die konventionelle Schmerzmedikation stand bei Kopfschmerzen sowie Rumpf-/Gliederschmerzen im Vordergrund. Bewegung an der frischen Luft und Spaziergänge zur Regeneration waren relevant bei Schwäche/Erschöpfung, Atemnot/Kurzatmigkeit sowie Husten. Phytotherapeutische Anwendungen waren insbesondere bei Husten bedeutsam. Ätherische Öle und Riechtraining hatten ihren Schwerpunkt bei Geruchs-/Geschmacksstörungen und Husten. Schlussfolgerungen: In Bezug auf das angewendete Spektrum der unterstützenden Therapieoptionen im Sinne des Selbstmanagements wurden einige sehr häufig und differenziert angewendet. Hier könnte man eine subjektiv empfundene "Nützlichkeit" annehmen. In der Literatur lassen sich für einige dieser Optionen auch Hinweise für eine mögliche Wirksamkeit finden, für andere nicht ohne weiteres. Diese unterstützenden Therapieoptionen könnten außerdem eine Möglichkeit sein, um einer abwartenden Hilflosigkeit proaktiv entgegenzuwirken.
