ABSTRACT

Objectives: Cardiac rehabilitation (CR) exercise classes in Singapore were either cancelled or suspended due to the ongoing COVID-19 pandemic. In response, a hybrid CR programme utilising telehealth was created to reduce reliance on in-person sessions. Our study aimed to assess early patients' impressions of this novel CR delivery method. Methods: Each hybrid CR programme comprises: (a) one CR orientation session via the Zoom video conferencing platform where patients interact with CR nurses and physiotherapists, (b) two 6-minute walk test fitness assessments (at baseline and upon completion), (c) five in-person supervised exercise classes and (d) two teleconsultation sessions (scheduled after exercise sessions 2 and 4) where CR physiotherapists review symptoms and discuss exercise prescriptions with patients over the phone. Upon programme completion, patients filled 2 anonymous online questionnaires - one assessing the videoconferencing component and another assessing the teleconsultation component and overall programme. Results: Seven patients underwent the hybrid CR programme. The majority were male (n=6, 86%), aged between 51 to 65 years (n=4, 57%) and had previously used a wide range of mobile applications (n=6, 86%). 100% of patients either agreed or strongly agreed that both videoconferencing and teleconsultation were: (a) easy to use, (b) as valuable as in-person sessions, (c) saved time and (d) had lower infection risk compared to in-person sessions (Figure). The overall ratings for videoconferencing, teleconsultation and the hybrid programme were 9.3, 9.6 and 9.6 (out of 10) respectively. All patients would definitely recommend the programme to others. Conclusion: Responses by participants of a novel hybrid CR programme utilising telehealth are highly encouraging. From a patient perspective, incorporation of telehealth to enable remote CR is feasible, acceptable and should be considered as an alternative CR delivery method.

ABSTRACT

Rationale: SARS-CoV-2, the virus that causes COVID-19, exhibits an ACE2-dependent airway epithelial tropism, and exploits host cell proteins to replicate and evade detection. The impact of asthma on COVID-19 susceptibility and severity is unclear. We sought to discover how genes encoding SARS-CoV-2-associated host proteins are expressed in primary human bronchial epithelial cells (HBECs), and how these genes are regulated by cytokines important in asthma. Methods: We compiled a list of 342 SARS-CoV-2-associated genes. We cultured primary HBECs at air-liquid interface in the absence of cytokine, or with interleukin (IL)-13, IL-17, interferon (IFN)-α, or IFN-γ. We used bulk RNA-seq and single cell RNA-sequencing to identify changes in gene expression. We correlated cytokine-regulated changes in SARS-CoV-2-associated transcripts on cytokine exposure in vitro with gene expression changes in transcriptomic profiling datasets derived from individuals with mild-to-moderate asthma and chronic obstructive pulmonary disease (COPD). Results: Transcripts encoding 332 of 342 (97%) SARS-CoV-2-associated proteins were detected in HBECs (≥1 RPM in 50% samples);85 (26%) were regulated by at least one cytokine (>1.5-fold change, FDR < 0.05). 21 and 19 of the 41 IL-13 responsive, SARS-CoV-2-associated genes identified in HBECs correlated with type 2 inflammatory gene signature scores in transcriptomic profiling datasets derived from individuals with mild-to-moderate asthma and COPD (p < 0.05);few IL-17 or interferon-responsive genes were correlated with their respective signatures in either dataset. Single cell RNA-sequencing revealed that 143 of the 332 (43%) SARS-CoV-2-associated transcripts detected in HBECs were differentially expressed between cell types (FDR < 0.05). 11 SARS-CoV-2-associated genes were modulated by IL-13 in a cell type-specific manner (>1.25-fold change, FDR < 0.05). Conclusions: Many genes encoding proteins associated with SARS-CoV-2 infection are expressed in HBECs, with substantial differences among cell subsets. IL-13 induces extensive changes in the expression of SARS-CoV-2-related genes that correlated with a measure of type-2 inflammation in vivo, providing a plausible basis for differences in outcome of COVID-19 in individuals with asthma.
