Data Sources: A search was performed using 50 keywords, focusing on the Indian/LMICs perspective, in PubMed, Cochrane Library, and Google Scholar. The key areas of the search were focused on diagnosis, phenoendotyping, non-biological therapies, selecting a biologic, assessment of treatment response, and management of exacerbation.

Pleural effusion guidelines from ICS and NCCP Section 1: Basic principles, laboratory tests and pleural procedures.

Pleural effusion is a common problem in our country, and most of these patients need invasive tests as they can't be evaluated by blood tests alone. The simplest of them is diagnostic pleural aspiration, and diagnostic techniques such as medical thoracoscopy are being performed more frequently than ever before. However, most physicians in India treat pleural effusion empirically, leading to delays in diagnosis, misdiagnosis and complications from wrong treatments.

Clinical characteristics governing treatment adjustment in COPD patients: results from the Swiss COPD cohort study.

Background: Chronic obstructive pulmonary disease (COPD) is a widespread chronic disease characterised by irreversible airway obstruction [1]. Features of clinical practice and healthcare systems for COPD patients can vary widely, even within similar healthcare structures. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy is considered the most reliable guidance for the management of COPD and aims to provide treating physicians with appropriate insight into the disease.

Risk Factors for Recurrent Exacerbations in the General-Practitioner-Based Swiss Chronic Obstructive Pulmonary Disease (COPD) Cohort.

Small Airways, Big Problem: Extrafine beclomethasone/formoterol in asthma and chronic obstructive pulmonary disease.

Asthma and chronic obstructive pulmonary disease (COPD) are common chronic respiratory diseases characterized by an inflammatory process that extends from the central to peripheral airways. Conventional pressurized metered-dose inhalers and most dry-powder inhalers emit drug particles too large to target the small airways effectively. Advancements in drug formulation have given rise to a new generation of inhalers that can generate aerosols with extrafine drug particles that leads to more effective aerosol penetration into the lung periphery.

Conventional flexible bronchoscopy during the COVID pandemic: A consensus statement from the Indian Association for Bronchology.

During the times of the ongoing COVID pandemic, aerosol-generating procedures such as bronchoscopy have the potential of transmission of severe acute respiratory syndrome coronavirus 2 to the healthcare workers. The decision to perform bronchoscopy during the COVID pandemic should be taken judiciously. Over the years, the indications for bronchoscopy in the clinical practice have expanded.
