Comment by Dr Mark Lavercombe:
This cohort study demonstrates the difficulty of differentiating sarcoidosis and tuberculosis. The diagnosis of tuberculosis within one year of sarcoidosis diagnosis occurred at a significant rate, suggesting the possibility of misdiagnosis. Further, subsequent diagnosis of sarcoidosis in patients treated for tuberculosis is significant after the first year of follow-up.

This population study examines the incidence of active tuberculosis diagnosis in a large population of patients with Type 2 Diabetes Mellitus. The authors demonstrate a significant protective effect in patients taking metformin, that is not seen with the use of other treatments including oral agents and insulin (despite improved glycaemic control). This suggests protection not only by improved glycaemic control but perhaps also via immune functions of metformin itself.
Comment by Dr Mark Lavercombe:
This paper outlines the clinical and pathophysiologic features of the unexpandable lung. The authors demonstrate a clear distinction between chronic 'trapped lung' and the 'lung entrapment' that occurs in active pleural disease states such as malignancy or infection.
Comment by Dr Mark Lavercombe:
The authors of this paper describe a cohort of patients with COPD who were stratified based on self-report of prior history of tuberculosis infection. Patients who admitted to prior Tb had more severe symptoms of COPD, poorer lung function and more frequent exacerbations. This difference was noted despite a lower prevalence of ongoing smoking in the tuberculosis group.
Comment by Dr Mark Lavercombe:
By using a Markov chain model, the authors of this study estimate likely future tuberculosis prevalence in China and the impact of various interventions. Their combined intervention model suggests a significant reduction in tuberculosis prevalence is achievable, and barriers to implementation are explored.
Comment by Dr Mark Lavercombe:
This important study demonstrates that patients with concomitant diabetes mellitus have different clinical features at diagnosis of tuberculosis, higher risk of adverse effects on treatment, slower sputum conversion, and lower treatment success at twelve months. Further data on the effect of diabetic control in patients treated for tuberculosis is required.
Comment by Dr Mark Lavercombe:
The authors of this paper outline the use of EBUS elastography for both qualitative and quantitative assessment of mediastinal lymphadenopathy for the presence of malignancy. Their promising findings suggest the need for further study to better define the elastographic features in both benign and malignant conditions, in order to guide the need for TBNA sampling.
