Depression is a common and chronic comorbidity in patients with interstitial lung disease.

Background And Objective: Little is known about depression in interstitial lung disease (ILD). The aim of this study was to determine the prevalence of depression, characterize the association of depression with clinical variables and describe the natural history of depression in patients with ILD.

Methods: In this prospective cohort study, clinical variables were recorded at baseline and 6 months.

Depression and functional status are strongly associated with dyspnea in interstitial lung disease.

Background: Little is understood about the characteristics of dyspnea in patients with interstitial lung disease (ILD), and its severity is likely influenced by multiple factors. Depression and functional status are known to influence dyspnea in patients with COPD. The aim of this study was to determine the relationship of dyspnea with clinical parameters, including depression and functional status, in patients with ILD.

A review of the six-minute walk test: its implication as a self-administered assessment tool.

Background: Promoting self-management and monitoring physical activity are important strategies in chronic heart disease (CHD) management. The six-minute walk test (6MWT) is a commonly used sub-maximal exercise test for measuring physical functional capacity.

Aim: The aim of this paper is to review the current literature on 6MWT relating to methodological issues as well as exploring the potential of the protocol to be adopted as a self-administered exercise test.
