The prognosis of patients with malignant pleural mesothelioma remains poor and although it is clear that multimodal therapy is necessary to improve long-term results, precise treatment schemes have not yet been unequivocally established. Single-modality therapy does not have a major impact on long-term survival and combined-modality therapies are being further evaluated. However, the relative contributions of chemotherapy, radiotherapy and surgery have not been clearly determined at the present time. ⋯ The role of post-operative radiotherapy has to be further elucidated. Further treatment options that are currently explored include hyperthermic intrapleural chemotherapy, immunotherapy, gene therapy and photodynamic therapy. However, no randomised comparisons are available yet.

We aimed to determine the coverage and yield of tuberculosis contact investigation, and compliance with guidelines, and to identify opportunities for improvement. Data were extracted from records on contacts of pulmonary tuberculosis patients at the Public Health Service (Amsterdam, the Netherlands) from 2008 to 2011. Additional data were obtained from the national tuberculosis register. ⋯ Starting treatment was associated with Dutch nationality (aOR 2.6, 95% CI 1.2-5.4) and being a close contact (aOR 10.5, 95% CI 1.5-70.7). Treatment completion was achieved by 129 (91%) of the 142 contacts who started treatment. Two areas for improvement were identified: further expanding LTBI screening, particularly among BCG-vaccinated contacts and contacts of sputum smear-negative index patients, and expanding preventive treatment among contacts with LTBI.

Current guidelines recommend measurement of pulmonary artery wedge pressure (PAWP) at end-expiration. However, this recommendation is not universally followed and may not be physiologically appropriate. We investigated the performance of end-expiratory PAWP in the evaluation of precapillary pulmonary hypertension patients. 329 spontaneously breathing patients undergoing right heart catheterisation were retrospectively classified as having a precapillary, post-capillary or mixed phenotype based on standardised clinical criteria. ⋯ Among all subjects, the magnitude of respirophasic variation in PAWP was positively correlated with body mass index and respirophasic variation in left ventricular end-diastolic pressure. A significant proportion of precapillary pulmonary hypertension patients have end-expiratory PAWP >15 mmHg. Spontaneous positive end-expiratory intrathoracic pressure may contribute; in those cases, PAWP averaged throughout respiration may be a more accurate measurement.

Individuals with chronic obstructive pulmonary disease (COPD) and asthma are an important but poorly characterised group. The genetic determinants of COPD and asthma overlap have not been studied. The aim of this study was to identify clinical features and genetic risk factors for COPD and asthma overlap. ⋯ Overlap subjects have more exacerbations, less emphysema and more airway disease for any degree of lung function impairment compared to COPD alone. We identified novel genetic variants associated with this syndrome. COPD and asthma overlap is an important syndrome and may require distinct clinical management.
