Review Comparative StudyInterrelational changes in the epidemiology and clinical features of nontuberculous mycobacterial pulmonary disease and tuberculosis in a referral hospital in Japan.
The incidence of nontuberculous mycobacterial pulmonary disease (NTM-PD) is increasing, while that of tuberculosis (TB) is decreasing in many industrialized countries, including Japan. However, the long-term evaluation of clinico-epidemiological features of NTM-PD in relation to TB are limited. We aimed to clarify the long-term changes in the epidemiology and clinical features of NTM-PD in relation to those of TB at a nationally-designated TB center in Japan. ⋯ The annual number of incident NTM-PD cases increased markedly. In contrast to patients with TB, the mean age of new NTM-PD patients did not increase in the last 10 years. Among MAC-PD patients, the proportions accounted for by the NB form increased significantly in both sexes.

Comparative StudyEconomic burden of incident interstitial lung disease (ILD) and the impact of comorbidity on costs of care.
Evidence about the economic burden related to interstitial lung diseases (ILDs) and the cost-driving factors is sparse. In the knowledge that distinct comorbidities affect the clinical course of ILDs, our study investigates their impact on costs of care within first year after diagnosis. ⋯ Comorbidities increase the already substantial costs of care in ILDs. To support patient-centred ILD care, not only highly cost-driving conditions that are inherent with high mortality themselves require systematic management. Moreover, conditions that are more rather restricting the patient's activities of daily living should be addressed - despite a low-cost impact.
