A practical guide to the diagnosis and management of suspected Non-tuberculous Mycobacterial Pulmonary Disease (NTM-PD) in the United Kingdom.

Non-tuberculous Mycobacterial Pulmonary Disease (NTM-PD) is a chronic disease characterised by progressive inflammatory lung damage due to infection by non-tuberculous mycobacteria (NTM). Global prevalence of NTM-PD is generally low but is rising, likely due to a combination of increased surveillance, increasing multimorbidity and improved diagnostic techniques. Most disease is caused by Mycobacterium avium complex species.

Clinical Implications of Functional Imaging in the Assessment of Bronchiectasis-Associated Sarcopenia.

Introduction: Bronchiectasis is a complex lung disease with poorly studied systemic manifestations. Patients with bronchiectasis-associated sarcopenia exhibit a specific differential profile of functional muscle phenotype (vastus lateralis, VL), which may be analyzed using imaging (ultrasound and magnetic resonance imaging, MRI).

Methods: Ultrasound and MRI were used to explore functional imaging parameters in quadriceps of 20 patients with stable bronchiectasis and 10 healthy controls.

Health inequalities in respiratory tract infections - beyond COVID-19.

Purpose Of Review: To discuss recent findings on the global burden of respiratory tract infections in underprivileged populations, highlighting the critical role of socioeconomic factors in the incidence and severity of these diseases, with a particular focus on health disparities affecting Indigenous communities.

Recent Findings: Pulmonary tuberculosis and lower respiratory tract infections, particularly those caused by Streptococcus pneumoniae and respiratory syncytial virus (RSV), continue to disproportionally impact populations in low-income countries and Indigenous communities worldwide. Indigenous children <5 years old bear the highest global burden of RSV infection, reflecting persistent social inequalities between Indigenous and non-Indigenous populations.

The textures of sarcoidosis: quantifying lung disease through variograms.

Sarcoidosis is a granulomatous disease affecting the lungs in over 90\% of patients. Qualitative assessment of chest CT by radiologists is standard clinical practice and reliable quantification of disease from CT would support ongoing efforts to identify sarcoidosis phenotypes. Standard imaging feature engineering techniques such as radiomics suffer from extreme sensitivity to image acquisition and processing, potentially impeding generalizability of research to clinical populations.

Airway Remodeling in Cystic Fibrosis Is Heterogeneous.

RATIONALE+OBJECTIVE/ Cystic fibrosis (CF) is characterized by bronchiectasis on imaging, while functionally evolving towards obstructive impairment. Despite its assumed importance in CF, small airway remodeling and its relation to bronchiectasis, is still poorly understood. METHOD/ On high-resolution computed tomography (HRCT, 600µm, CF=21, control=6) and micro-computed tomography (µCT, 150µm, CF=3, control=1) scans of inflated explant lungs, AV% (airway/total lung volume) was calculated as marker for bronchiectasis, while airway segmentation was used for generation analysis.

Etiology and clinical features of children with bronchiectasis-Insight from Chinese experience.

Surgery for bronchiectasis in children living with HIV: A case series from a low- to middle-income country.

Background: Bronchiectasis (BE) in children living with HIV (CLWH) remains a significant cause of morbidity and mortality, especially in tuberculosis (TB)-endemic low- and middle-income countries. Treatment modalities for BE in CLWH currently focus mainly on prevention of infections and management of symptoms, while surgical management is indicated for a select group. In contrast, surgical management in non-cystic fibrosis BE is well established.

Bronchiectasis-COPD Overlap Syndrome: A Comprehensive Review of its Pathophysiology and Potential Cardiovascular Implications.

Bronchiectasis-Chronic Obstructive Pulmonary Disease Overlap Syndrome (BCOS) is a complex pulmonary condition that merges bronchiectasis and chronic obstructive pulmonary disease (COPD), presenting unique clinical challenges. Patients with BCOS typically exhibit a range of symptoms from both conditions, including a chronic productive cough, reduced lung function, frequent exacerbations, and diminished exercise tolerance. The etiology of BCOS involves multiple factors such as genetic predisposition, respiratory infections, tobacco smoke, air pollutants, and other inflammatory mediators.

Automated method of bronchus and artery dimension measurement in an adult bronchiectasis population.

Aim: Bronchiectasis (BE) is a disease defined by irreversible dilatation of the airway. Computed tomography (CT) plays an important role in the detection and quantification of BE. The aim of this study was three-fold: 1) to assess bronchus-artery (BA) dimensions using fully automated software in a cohort of BE disease patients; 2) to compare BA dimensions with semi-quantitative BEST-CT (Bronchiectasis Scoring Technique for CT) scores for BE and bronchial wall thickening; and 3) to explore the structure-function relationship between BA-method lumen dimensions and spirometry outcomes.
