The aim of the study was to investigate the prognostic value of right heart catheterisation variables measured during exercise. 55 incident patients with idiopathic, familial or anorexigen-associated pulmonary arterial hypertension (PAH) underwent right heart catheterisation at rest and during exercise and 6-min walk testing before PAH treatment initiation. Patients were treated according to recommendations within the next 2 weeks. Right heart catheterisation was repeated 3-5 months into the PAH treatment in 20 patients. ⋯ Change in 6-min walk distance from baseline to 3-5 months under PAH treatment was highly correlated with change in exercise cardiac index (r=0.746, p<0.001). The most significant baseline covariates associated with survival were change in systolic pulmonary artery pressure from rest to exercise and exercise cardiac index (hazard ratio 0.56 (95% CI 0.37-0.86) and 0.14 (95% CI 0.05-0.43), respectively). Change in pulmonary haemodynamics during exercise is an important tool for assessing disease severity and may help devise optimal treat-to-target strategies.

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.
