Oxygen (O ) concentration in the breath sample can be used as a quality marker. This study investigated the characteristics of O concentration in the breath sample and the impact of using a correction factor in real-time breath measurement. This study includes two separate groups of patient data. Part 1 of the study analysed the patient's ability to deliver end-expiratory breath samples over a 2-year period (n=564). Part 2 of the study analysed a separate group of patients (n=47) with additional data to investigate the O characteristics and the role of correction factor in breath test. The results indicated 95.4% of 564 patients were able to achieve an O concentration below 14% in their end-expiratory breath. Part 2 of the study revealed that the distribution of O concentration was between 9.5% and 16.2%. Applying a correction factor to predict the end-expiratory H and CH values led tbreath collection.COVID-19 is a major public health pandemic. Risk factors for severe infection and poorer outcomes include cardiovascular disease, obesity, type 2 diabetes mellitus and non-alcoholic fatty liver disease (NAFLD). Lifestyle interventions, including diet and physical activity modifications, are the current recommended treatment for NAFLD. In this communication, the authors discuss the crossover link between NAFLD and severe COVID-19 infection and the impact of essential public health measures to suppress the spread of COVID-19 on exercise and physical activity participation in patients with NAFLD. The future of exercise prescription and the potential use of digital technology in addressing NAFLD healthcare needs in the COVID-19 era are also explored.During mitosis, chromatin condensation is accompanied by a global arrest of transcription.
