SingStrong-A singing and breathing retraining intervention for respiratory and other common symptoms of long COVID: A pilot study.

Background: Management of Long COVID (LC) is hugely challenging for clinicians. This pilot study evaluated a breathing retraining and singing programme (SingStrong for LC) to address common LC symptoms. The study hypothesized that this intervention would improve symptoms impacting disordered breathing and participant wellbeing. Methods: The 10-week, bi-weekly online programme was comprised of a 45-min class of mindfulness, breathing retraining, vocal exercises, and singing. Sessions were recorded for non-attenders and conducted by a trained vocal coach experienced in respiratory cohorts. Persons with a confirmed COVID-19 diagnosis and persisting symptoms were invited to participate. Demographic and COVID-19 data were collected, and the DePaul Symptom Questionnaire Short Form (DSQ- SF) and COVID-19 Yorkshire Rehab Screen questionnaires were administered. Post-intervention focus groups were also conducted. Results: Of 27 (F = 23(85%)) participants recruited, data from 21 who completed at least 10 (50%) classes were analysed. Participants showed significant pre-post-intervention improvements in all breathlessness symptoms (at rest: P < 0.001; dressing: P = 0.01; stairs: P < 0.001), fatigue (P = 0.03), usual activities (P = 0.04), pain/disability (P = 0.03), voice quality (P = 0.01), and communication/cognition (P = 0.04). Pre-post number of instances meeting DSQ-SF criteria for myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS) decreased by a net of nine cases (14.3%). No association between COVID-19 hospitalisation status and diagnosis of ME/CFS was identified. Qualitative feedback from eight participants was overwhelmingly positive with all reporting improvements in breathing and general well-being. Conclusion: The SingStrong programme shows promise as a viable treatment option for LC sufferers. Future studies are required to further investigate the efficacy of this intervention.

"SingStrong": Singing for better lung health in COPD - A pilot study.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) affects up to 440,000 people in Ireland. Multiple domains of biopsychosocial health are affected. Community-based interventions supporting behavioral change and self-management are advocated. The aim of this pilot study was to evaluate the efficacy of an 8-week singing intervention, "SingStrong", to improve biopsychosocial wellness in persons with COPD. METHODS: Seventy-eight adults with COPD were recruited from three COPD Support groups in the Irish Mid-west. Pre and post-intervention testing performed by physiotherapy and nursing staff comprised Six-Minute Walk Test (6MWT), COPD Assessment test (CAT), Hospital Anxiety and Depression Scale (HADS), and Spirometry: FEV1, FVC, FEV1/FVC. The intervention was a weekly one-hour group class for eight weeks led by a trained choir leader at each site. This included physical and vocal warm-up, breathing exercises and singing. Participants were given a songbook based on their song preferences and a CD with vocal, breathing exercises and songs, and encouraged to practice daily. Semi-structured focus groups were conducted post intervention. Parametric or non-parametric t-tests were conducted to establish significance. RESULTS: Fifty-eight (74%) participants who attended at least 4/8 session were re-tested. There was a statistically significant improvement in 6MWT (p = .02), non-significant improvements in CAT (p = .24) and HADS Depression (p = .238), and non-significant worsening in HADS Anxiety (p = .34). All qualitative feedback was positive, including improvements in breathing, quality of life and intervention enjoyment. PRINCIPAL CONCLUSIONS: Singing for lung health has positive implications for persons with COPD. Future longer studies should examine outcomes of exacerbation level, hospitalization and medication use.

The addition of raspberries and blueberries to a starch-based food does not alter the glycaemic response.

It is now known that health benefits associated with diets rich in fruit and vegetables may be partly derived from intake of polyphenols. Berry polyphenols may influence carbohydrate metabolism and absorption and hence postprandial glycaemia. To date, studies related to polyphenol effects on the glycaemic response have been completed only in liquids using either monosaccharides or disaccharides. It remains to be determined whether berries known to be rich in polyphenols can reduce the glycaemic response (GR) to a solid polysaccharide meal. The aim of the present study was to investigate whether berries alter postprandial hyperglycaemia and consequently the GR to a starchy food. Blood glucose was tested on seven occasions, on three occasions using a reference food and on four occasions using pancakes supplemented with either raspberries or blueberries or control pancakes containing similar amounts of fructose and glucose. Results showed that there were no differences in GR (blueberry 51·3 (SEM 5·7); raspberry 54·7 (SEM 5·6); blueberry control 43·9 (SEM 4·2); raspberry control 41·8 (SEM 6·4)), GR area under the curve or satiety index between any of the tests. The present study indicates that the ability of berries to reduce blood glucose from starch-based foods is unsubstantiated.
