Summary: The study demonstrated that Apocynin can prevent and treat bronchopulmonary dysplasia (BPD) by reducing oxidative stress, blocking inflammation, and enhancing antioxidant status. These effects may be achieved through reducing inflammatory cell infiltration, decreasing proinflammatory cytokines, lowering NLRP3 inflammasome activity, and increasing Nrf2 levels.

Summary: Epidemiological studies show that COPD is linked to changes in intestinal health. Cigarette smoking, a major cause of COPD, affects the gastrointestinal system and promotes intestinal diseases. Gut-lung interactions occur through circulating inflammatory cells and mediators. Gut microbiota dysbiosis, systemic hypoxia, and oxidative stress play a role in the gut-lung axis. This review summarizes the possible mechanisms of gut-lung interactions in COPD and highlights potential therapies for intestinal dysfunction.

Summary: Patients with pulmonary fibrosis experience early oxyhemoglobin desaturation under effort, limiting their exercise ability and quality of life. Recent studies have shown that outpatient oxygen administration significantly improves stress dyspnoea and quality of life in hypoxemic patients. The authors tested the hypothesis that correcting hypoxemia could reduce the increase in respiratory effort during the 6 min walking test.

Summary: Metoprolol may be associated with increased risk of exacerbations in chronic obstructive pulmonary disease (COPD), but its effects on lung function are not significant and do not persist. Early lung function reduction and baseline bronchodilator responsiveness do not interact with treatment assignment to predict exacerbations, except for baseline FVC bronchodilator responsiveness, which is associated with a 60% higher rate of severe or very severe exacerbations.

Summary: The study evaluated the effect of OSAS and CPAP therapy on choroidal structural changes and CVI in patients with OSAS. OSAS was associated with stromal edema in the choroid, which improved after 12 months of CPAP therapy. CVI can be an important parameter for monitoring patients with OSAS.

Summary: In patients with COPD, lung-conduction exercises (LCE) have shown some improvement in symptoms and quality of life, but pulmonary rehabilitation (PR) demonstrates more significant improvements compared to standard care (SC) alone. Further studies with larger sample sizes, longer duration, and additional outcome measures are needed to explore the precise use and benefits of LCE.

Summary: Oxidative stress is a main factor causing diaphragm dysfunction in COPD, while exercise plays a positive role in preventing and improving this dysfunction. The effects of exercise on oxidative stress and diaphragm function depend on the intensity, duration, and style of exercise.

Summary: This study investigated the effect of prompt vs delayed initiation of long-acting bronchodilators on exacerbation risk in patients with chronic obstructive pulmonary disease (COPD). The results showed that initiating long-acting bronchodilator therapy within 30 days of COPD diagnosis prolonged time to first exacerbation and reduced the rate of moderate or severe exacerbations.

Summary: This study evaluated the impact of pulmonary rehabilitation on heart rate recovery (HRR) in individuals with asthma compared to those with COPD. The findings showed that individuals with asthma had a lower prevalence of slow HRR than those with COPD. However, exercise training significantly improved exercise capacity in both populations.

Additionally, environmental factors such as the size of living areas and proximity to main roads play a significant role in COPD exacerbations.

Summary: This study investigated the role of progression of training volume in intramuscular adaptations in patients with COPD undergoing resistance training. The findings suggest that continued progression of training volume can lead to improvements in fiber type distribution, muscle protein levels, and quadriceps endurance in patients with COPD. These findings highlight the importance of continued progression of training volume for counteracting quadriceps dysfunction in this population.

Summary: In this study, the effects of a selective androgen receptor modulator, GSK2881078, on leg strength in patients with chronic obstructive pulmonary disease (COPD) were investigated. The results showed that GSK2881078 increased leg strength in male COPD patients, but had no significant effect on female patients. The study also found that the use of GSK2881078 was associated with reversible side effects, such as reductions in high-density lipoprotein cholesterol and transient elevations in hepatic transaminases.

Summary: This systematic review and meta-analysis aimed to investigate postinfection fatigue among survivors of SARS-CoV-2 and associated factors. The results showed that a significant proportion of survivors experienced fatigue, but this fatigue reduced over time. Female gender, age, physical functioning, breathlessness, and psychological distress were frequently reported associations with fatigue.

Summary: This study aimed to explore perspectives on spirometry provision in primary care and the potential for artificial intelligence (AI) decision support software to improve quality and interpretation. The study found historical challenges and the impact of the pandemic on inequity in spirometry provision. It suggests delivering services closer to patients’ homes by appropriately trained staff and highlights the potential role of AI in supporting clinicians. However, sufficient validation of the software is crucial for clinician and healthcare commissioner trust in the process.

Summary: People with respiratory disease have an increased risk of developing frailty, and rehabilitation plays an important role in managing frailty in this population. However, identifying frailty and delivering rehabilitation for these individuals remain challenging. This workshop aimed to outline definitions and concepts, synthesize evidence, and explore adaptation of programs for people with respiratory disease and frailty. Participants discussed the frailty rehabilitation paradox and highlighted the need for comprehensive assessment, tailored support, and exercise prescriptions that consider symptom burden and comorbidities. Research is required to expand understanding and explore telerehabilitation or home-based pulmonary rehabilitation for this population.

Summary: This study investigated the participation and completion of rehabilitation programs by patients with coexisting COPD and CHF, and compared the outcomes. The results showed that patients with COPD and CHF had lower participation in cardiac rehabilitation, but higher participation in pulmonary rehabilitation. Patients with COPD had better performance in the incremental shuttle walk test following rehabilitation compared to patients with COPD+CHF. The improvements in the 6-min walk test, quality of life, and mood state were similar between the two groups, regardless of diagnosis.
