Introduction: Interstitial lung diseases (ILDs) include a wide variety of chronic progressive pulmonary diseases characterized by lung inflammation, fibrosis and hypoxemia and can progress to respiratory failure and even death. ILDs are associated with varying degrees of quality of life impairments in affected people. Studies on the quality of life in patients with ILDs are still limited, and there are few studies with long-term follow-up periods in these patients., Methods: Data from patients who were clinically diagnosed with ILDs in the Respiratory Department, Beijing Chaoyang Hospital, Capital Medical University from January 2017 to February 2018 were collected. Clinical status and HRQoL were assessed at baseline and subsequently at 6- and 12-month intervals with the LCQ, mMRC, HADS, SF-36, and SGRQ. Multivariate linear regression was used to evaluate the determinants of the decline in HRQoL., Results: A total of 139 patients with idiopathic interstitial pneumonia (IIP) and 30 with connective tissue disease-associated ILD (CTD-ILD) were enrolled, 140 of whom completed the follow-up. The mean age was 63.7 years, and 92 patients were men. At baseline, the decline in HRQoL assessed by the SF-36 and SGRQ was significantly associated with the mMRC, LCQ and HADS depression score. In the follow-up, changes in FVC%, DLco%, mMRC and LCQ were significantly associated with changes in HRQoL., Conclusions: HRQoL in both IIP and CTD-ILD patients deteriorates to varying degrees, and the trend suggests that poor HRQoL in these patients is associated with many determinants, primarily dyspnea, cough and depression. Improving HRQoL is the main aim when treating patients living with ILDs., Competing Interests: The authors have declared that no competing interests exist.

Background: When exacerbation of chronic obstructive pulmonary disease (AECOPD) occurs frequently, patients have high levels of airway and systemic inflammation and a poor quality of life. This study compared the nature and course of systemic and airway inflammation during AECOPD between patients who experienced frequent exacerbations and those with non-frequent exacerbations., Material and Methods: Consecutive hospitalized patients with AECOPD were recruited and divided into 2 groups according to the frequency of AECOPD they had experienced in the previous year. Frequent exacerbators (defined as 2 or more AECOPD in the previous year) and non-frequent exacerbators (defined as zero or 1 AECOPD in the previous year). Inflammatory (interleukin 6, interleukin 8, myeloperoxidase, and C-reactive protein) and clinical (dyspnea, COPD assessment test (CAT), and peak expiratory flow) indices were assessed on the day of admission before starting therapy, day 7 of treatment, the day of planned discharge (day 10-14), and 8 weeks after discharge., Results: We analyzed data from 135 patients; 78 (57.8%) were non-frequent exacerbators and 57 (42.2%) were frequent exacerbators. In both groups, the inflammatory and clinical indices at day 7, the day of planned discharge (day 10-14), and 8 weeks were significantly improved compared to those at admission. Frequent exacerbators had a smaller reduction in their inflammatory indices and CAT scores between exacerbation onset and all the other time points compared with infrequent exacerbators., Conclusions: Frequent exacerbators have a reduced response to treatment of AECOPD in terms of inflammatory indices and quality of life.

Objective: To improve time to treatment, the effects of acute myocardial infarction (AMI) symptoms on prehospital delay time (PDT) were investigated., Methods: Patients with AMI completed a questionnaire on their AMI symptoms and their general knowledge of AMI symptoms., Results: In total, 116 patients completed questionnaires. The mean PDT was 7.3 ± 2.4  h; the median PDT was 2.2 h. Each patient experienced a mean of 3.6 symptoms during their AMI. PDT was significantly shorter in the following groups: patients with chest compression pain/chest discomfort, profuse sweating or dyspnoea than in patients with other symptoms; patients presenting with typical rather than atypical symptoms; patients with pain scores >6 compared with scores ≤6; patients who were aware rather than unaware of AMI symptoms. Patients actually having AMI symptoms and patients being aware of AMI symptoms were inversely correlated with PDT. There was a linear relationship between pain scores and PDT., Conclusion: Public awareness of AMI symptoms should be enhanced, in order to shorten PDT and improve AMI survival rates.
