Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality throughout the world. The coexistence of COPD and obstructive sleep apnea (OSA) (i.e., overlap syndrome) has been reported in several studies. Both disorders independently increase the risk of cardiovascular complications. Hence, there is a theoretical possibility that cardiovascular parameters may be worse in patients with overlap syndrome compared to those with only COPD. However, this has been sparsely assessed in the literature. This study aimed to compare the clinical characteristics, echocardiography, and sleep parameters amongst COPD patients with and without sleep-related breathing disorders (SRBD). This observational, cross-sectional study included 30 patients with stable COPD. All participants underwent a detailed clinical evaluation, followed by level 1 polysomnography (PSG). Each participant underwent echocardiographic evaluation to estimate mean pulmonary artery pressure from right ventricular systolic pressure (RVSP). Based on their PSG findings, participants were classified into non-SRBD and SRBD groups. Both groups were further compared with respect to clinical characteristics, echocardiographic, and PSG parameters. We found that most of the participants (93.3%) were male, and the mean age of the study population was 56±8.2 years. The only SRBD identified in this study was OSA, which was observed in 80% of participants. In this group, OSA was not associated with obesity. Systemic hypertension (50%) was the most common comorbidity, followed by diabetes mellitus (26.67%), but both were not significantly different between the groups. The mean RVSP was significantly higher amongst OSA patients than non-OSA patients (41.25±14.98 versus 30.83±5.84, respectively; p=0.01). OSA was seen in 80% of participants with stable COPD, even in the absence of obesity. The presence of OSA was associated with a higher RVSP in this patient group.

Ladakh is a hilly Himalayan dry desert, situated at an altitude of >11000 feet. Studies have demonstrated that the spirometric values of high-altitude residents are significantly higher than those of low-landers. This is a retrospective observational study that analyzes the spirometry pattern in chronic lung diseases among people from Ladakh. Enrolled subjects were clinic-radiologically diagnosed and had at least one spirometry report. The spirometric parameters were analyzed for normal and abnormal patterns of lung function. The abnormal patterns were further classified into types of ventilator defects and their severity. A total of 122 cases were included, with 67 (55%) men. The mean age was 52.2±15.4 years. The most common diseases were chronic obstructive pulmonary disease (COPD) in 51 cases (41%), and asthma in 41 (33%). The median predicted percentage of forced vital capacity (FVC) was 116% (63-179%) with >100% in 105 (85%) patients. The median predicted percentage of the forced expiratory volume in the 1st second (FEV1) was 113% (99-175%) with >100% in 90 (74%) patients. FVC was reduced in 9 (7%) cases, normal in 62 (51%), and more than normal in 49 (42%), with 11 (9%) cases having >150% of the predicted percentage. FEV1 was reduced in 9 (8%) cases, normal in 67 (55%), and more than normal in 46 (37%) cases, with >150% predicted seen in 10 (8%) cases. Similarly, overall, the predicted percentages of both FVC and FEV1 were >100% in all obstructive airway diseases as well as in the separate COPD and asthma subgroups. FVC and FEV1 amongst chronic lung disease patients from Ladakh were more than normal in the majority. These higher values of spirometry led to incorrect disease severity classifications and disease patterns. We propose that studies should be done to devise local reference equations for spirometry for Himalayan high-altitude residents of India.

Diabetes mellitus (DM) is a metabolic syndrome associated with chronic hyperglycemia, which results in various acute and chronic complications. DM leads to a state of chronic low-grade inflammation, which can have adverse effects on pulmonary functions. There have been contradictory studies related to the relationship between defects in lung functions in diabetic individuals and their correlation with glycemic control and systemic inflammatory markers. The present study aims to compare pulmonary function in controlled and uncontrolled diabetes in the Indian population while exploring the link between inflammatory markers and lung functions in diabetic patients. This observational, case-control study was conducted in the Department of Biochemistry at Sri Guru Ram Das Institute of Medical Sciences and Research in Amritsar, Punjab, on 116 subjects suffering from DM in the age group of 30-65 years. 58 diabetic patients with poor glycemic control [glycated hemoglobin (HbA1c)>7%] and 58 diabetic patients with good glycemic control served as controls (HbA1c≤7%). The duration of the study was two years. Blood samples of each patient were investigated for glycemic control, high-sensitivity C-reactive protein (hsCRP), and serum fibrinogen. Spirometry as a pulmonary function test was undertaken for all participants. The statistical analysis of good and poor glycemic control diabetics showed that the average duration of disease (in years) was 8±5 and 10.2±5.4, respectively. A significant positive correlation was found between inflammatory markers (hsCRP and fibrinogen) and HbA1c and fasting blood glucose. A substantial decline in forced vital capacity and normal values of forced expiratory volume in the first second was observed in poor glycemic control diabetics, depicting a restrictive pattern of lung disease. Lung damage is seen to be more prevalent in patients with a longer duration of disease and increased levels of inflammatory markers. Chronic inflammation due to DM can lead to fibrosis and destruction of lung tissue, resulting in the development of diabetic lung disease, which includes a decline in lung function, an increased risk of infection, and an increased risk of respiratory failure. Therefore, it is essential for individuals with DM to have regular pulmonary function tests and to manage their diabetes to minimize the impact on their lung health.

Endobronchial ultrasound (EBUS)-guided mediastinal cryobiopsy is a new modality for sampling mediastinal lymph nodes. The data regarding the diagnostic yield and utility of mediastinal cryobiopsy is still limited. Consecutive patients who were undergoing EBUS-guided transbronchial needle aspiration (EBUS-TBNA) were recruited in this study. We subjected the enrolled patients to EBUS-guided mediastinal cryobiopsy after obtaining their informed consent. The final diagnosis was made with a clinical-pathological-radiological assessment and clinical-radiological follow-up. A total of 101 patients were enrolled in the study. Adequacy in sampling achieved in EBUS-TBNA was 92.07%, compared to 98.01% achieved in EBUS-TBNA with mediastinal cryobiopsy. Diagnostic yields achieved in EBUS-TBNA and EBUS-TBNA with mediastinal cryobiopsy were 67.32% and 86.13%, respectively (p=0.001). EBUS patterns failed to predict the utility of mediastinal crobiopsy. No significant complications were observed. To conclude, EBUS-guided mediastinal cryobiopsy improves yield in patients undergoing EBUS-TBNA.

Cystic fibrosis (CF), a multisystem disease primarily affecting the lungs, arises due to pathogenic mutations in the CF transmembrane conductance regulator (CFTR) gene. This study embarked on a bibliometric analysis to survey the use of CFTR modulators in CF treatment. Utilizing the Scopus database, a comprehensive search was executed, incorporating terms related to CF and CFTR modulators. Various document types up to July 19, 2023, were included, with citation counts forming the basis of our analyses. Trends, contributor countries, leading institutions, top authors, journals, keywords, and annual citation trends were evaluated. Our search retrieved 2317 records, predominantly articles. The United States dominated in both publications and citations, followed by the United Kingdom. The University of Alabama, Birmingham, and Vertex Pharmaceuticals, Boston, were among the top institutions. Rowe S.M. was identified as a top-cited author. The Journal of Cystic Fibrosis emerged as the leading journal in terms of publication volume, while the New England Journal of Medicine had the highest citation count. The most-cited article addressed a CFTR potentiator's efficacy in patients with the G551D mutation. The keyword "Cystic fibrosis" appeared most frequently. This bibliometric analysis underscores the significant research focus on CF, especially concerning CFTR modulators. The results highlight the pivotal role of certain countries, institutions, authors, and journals in the progression of CF research, offering insights into current trends and future research directions.
