Abstract

Background: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a leading driver of morbidity, mortality and health-care expenditure, and simple admission biomarkers that grade severity are needed in resource-limited settings. The platelet–lymphocyte ratio (PLR) integrates thrombo-inflammation and relative lymphopenia, yet Indonesian evidence linking it to exacerbation severity and length of stay (LOS) remains limited. Objective: To evaluate admission PLR as a predictor of exacerbation severity and prolonged length of stay in hospitalised patients with AECOPD. Methods: In this dual-center analytical cross-sectional study, 141 hospitalised AECOPD patients at Dr. M. Djamil General Hospital, Padang and RS Madina Bukittinggi (January–December 2024) were analysed. Admission PLR was related to Anthonisen severity and LOS (>7 days) using Kruskal–Wallis and Mann–Whitney tests, Spearman correlation, ROC analysis and multivariable logistic regression (adjusted odds ratios, aOR). Results: Most patients were male (86.5%) and heavy smokers (87.5%). Mean PLR rose across severity strata (mild 126.8, moderate 192.3, severe 444.9; p<0.001) and correlated moderately with severity (ρ=0.534) but weakly with LOS (ρ=0.295). PLR discriminated severe exacerbation with excellent accuracy (AUC 0.929; cut-off ≥216.3, sensitivity 100%, specificity 73.2%). After adjustment, PLR independently predicted severe exacerbation (aOR 3.73 per 50 units, 95% CI 1.87–7.42), whereas prolonged stay was driven by pneumonia (aOR 6.40) rather than PLR. Conclusion: Admission PLR is an inexpensive, widely available biomarker that accurately identifies severe AECOPD and may support early risk stratification, although it should not be used alone to predict length of stay, which is governed chiefly by comorbidity.

Abstract

Exercise-Induced Asthma (EIA), also known as exercise-induced bronchospasm (EIB), is a condition in which the airways become blocked after exercise. Although exercise can cause asthma attacks, a lack of exercise can make asthma worse. Apart from taking medication, exercise can help control asthma attacks, and help improve the quality of life of the asthmatic population. Exercise can be done by people with mild to moderate degrees of airway obstruction, just like healthy people. Swimming, walking, cycling, playing ball and aerobics are good sports for asthma patients. Exercise-Induced Asthma (EIA) can also prevent asthma patients from exercising and affect their quality of life. The diagnosis of EIA is based on symptoms and spirometry or bronchial provocation tests. Nonpharmacological approaches, including avoidance of precipitating factors, are essential. SABA before exercise is also widely used and recommended as first-line therapy. Inhaled corticosteroids are recommended when asthma control is less than optimal. Leukotriene receptor antagonists (LTRA) and mast cell stabilizing agents (MCSA) are potential options.

Abstract

Byssinosis, also known as brown lung disease or Monday fever/Monday dyspnea, is a form of respiratory symptoms caused by exposure to raw non-synthetic textile materials during the production process in the industrial sector and is considered as a form of occupational lung disease. An increase in the prevalence of occupational lung diseases has been found in developing countries, particularly in South Asia. The etiology of byssinosis is the exposure to cotton dust in the textile industry, caused by exposure to endotoxins from the cell walls of gram-negative bacteria found in the dust of various plant fibers, including cotton. Diagnosing byssinosis requires taking a medical history, performing a physical examination, and conducting supporting examinations such as chest X-ray, high-resolution chest CT scan, and pulmonary function tests. In pulmonary function testing using spirometry, a decrease in the FEV1/FVC ratio may be observed. Based on clinical symptoms and lung function tests, the severity of byssinosis can be assessed using Schilling criteria. Inhalation medications such as short-acting and long-acting beta-agonists are choices for pharmacological management of byssinosis. Inhaled corticosteroids can be used in severe clinical conditions.

Abstract

Background: Amiodarone is the most effective antiarrhythmic agent for maintaining sinus rhythm, yet its long-term use is constrained by extracardiac toxicity, of which pulmonary toxicity is the most feared because it carries appreciable mortality and is frequently misdiagnosed. No contemporary meta-analysis has isolated amiodarone-induced pulmonary toxicity as the single primary endpoint across cardiac arrhythmia and heart-failure populations; this study quantified that risk. Methods: PubMed/MEDLINE, Scopus and Web of Science were searched for placebo- or usual-care-controlled randomised controlled trials (RCTs) of oral amiodarone in adults with cardiac arrhythmia or heart-failure indications reporting pulmonary toxicity. Two reviewers extracted 2×2 data and assessed risk of bias with Cochrane RoB 2.0. Because the outcome was dichotomous, the risk ratio (RR) was pooled using a DerSimonian–Laird random-effects model, with the odds ratio (OR) and Peto OR as corroborative measures. Results: Nine RCTs comprising 6,209 patients (3,175 amiodarone; 3,034 control) were included. Pulmonary toxicity occurred in 77 of 3,175 amiodarone-treated patients (2.43%) versus 42 of 3,034 controls (1.38%). Amiodarone significantly increased pulmonary-toxicity risk (RR 1.70, 95% CI 1.17–2.45, p = 0.005), with no detectable heterogeneity (I² = 0%). The OR (1.74) and Peto OR (1.81) were concordant, and the estimate remained harmful under every single-study deletion (RR 1.46–2.64). Higher-dose strata showed a numerically larger effect (RR 2.50) than lower-dose strata (RR 1.69; subgroup p = 0.48). Conclusion: Amiodarone was associated with an approximately 70% relative increase in pulmonary-toxicity risk versus placebo, a robust and homogeneous finding. The absolute excess was modest (about one additional case per 95 patients treated), supporting continued use with structured baseline and periodic pulmonary surveillance, particularly at higher maintenance doses and longer durations.

Abstract

Catamenial pneumothorax (CP) is a rare and recurrent spontaneous pneumothorax in women, typically occurring from 24 hours before menstruation to 72 hours afterward. While once considered uncommon, CP is now recognized in up to 30% of pneumothorax cases among women. This study aims to provide a comprehensive literature-based analysis of the etiology, diagnosis, and multidisciplinary management of CP. The research method used is a literature review that analyzes clinical cases, diagnostic imaging, histopathological findings, and treatment outcomes from various databases and published case reports. Findings suggest that while the etiology remains multifactorial—including diaphragmatic defects, lymphovascular dissemination, and hormonal influences—the use of video-assisted thoracic surgery (VATS) combined with pleurodesis and postoperative hormonal therapy (e.g., GnRH analogs) significantly reduces recurrence rates, down to 0% in some combined therapy cases. Imaging modalities like MRI during menstruation increase diagnostic accuracy. The study also underscores the importance of surgical timing, hormonal therapy continuity, and long-term monitoring for recurrence prevention. Implications of this study include the need for standardized treatment protocols and the incorporation of gynecological and thoracic collaboration in managing CP. Future research should explore biomarkers and prospective multicenter trials to refine diagnostic and therapeutic strategies.

Abstract

Hyperbaric Oxygen Therapy (HBOT) is a medical intervention that involves administering pure oxygen at high pressure for various conditions like decompression sickness, severe anemia and including carbon monoxide (CO) poisoning. This literature review aims to evaluate the effectiveness of HBOT in reducing neurocognitive symptoms caused by CO poisoning, as well as to review the mechanisms, indications, contraindications, and application of Hyperbaric Oxygen Therapy in Carbon Monoxide Poisoning. The review findings indicate that HBOT significantly enhances tissue oxygenation and accelerates the healing process, which can reduce the risk of neurocognitive damage. Hyperbaric Oxygen Therapy has also been found to modulate inflammatory responses, which play a crucial role in the recovery of patients with CO poisoning. However, some studies show variations in the long-term effectiveness of HBOT on neurocognitive symptoms, highlighting the need for further research. This literature review concludes that HBOT offers significant benefits in the treatment of CO poisoning; however, further research is needed to optimize clinical use and ensure its long-term effectiveness.
