Combined pulmonary fibrosis and emphysema syndrome: a radiologic perspective

Chronic obstructive pulmonary disease (that includes emphysema) results in significant morbidity and mortality worldwide. Idiopathic pulmonary fibrosis (IPF) is also a chronic and progressive parenchymal lung disease with an average survival of less than 5 years after diagnosis. Combined pulmonary fibrosis and emphysema (CPFE) is an important but still underdiagnosed syndrome. Its diagnosis is based on the radiological findings at computed tomography which consists of emphysema of the upper lung zones and fibrosis of the lower lung zones. Since this syndrome has a very bad prognosis, even worse than isolated finding of emphysema or fibrosis alone, early recognition and rapid treatment are important. In this article we will review and elucidate the radiologic appearance of this syndrome and highlight its clinical importance

Measurement of the B0-anti-B0-Oscillation Frequency with Inclusive Dilepton Events

The $B^0$-$\bar B^0$ oscillation frequency has been measured with a sample of 23 million \B\bar B pairs collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we select events in which both B mesons decay semileptonically and use the charge of the leptons to identify the flavor of each B meson. A simultaneous fit to the decay time difference distributions for opposite- and same-sign dilepton events gives $\Delta m_d = 0.493 \pm 0.012{(stat)}\pm 0.009{(syst)}$ ps$^{-1}$.Comment: 7 pages, 1 figure, submitted to Physical Review Letter

Pulmonary rehabilitation, physical activity, respiratory failure and palliative respiratory care

The CIRO Academy in Horn (the Netherlands) organised a 2-day meeting to present and discuss the studies published in 2017 pertaining to key priority areas of respiratory and critical care medicine. This review summarises studies focussing on pulmonary rehabilitation and exercise training, physical activity, chronic respiratory failure and palliative respiratory care published in 2017

An official European respiratory society statement on physical activity in COPD

This European Respiratory Society (ERS) statement provides a comprehensive overview on physical activity in patients with chronic obstructive pulmonary disease (COPD). A multidisciplinary Task Force of experts representing the ERS Scientific Group 01.02 ''Rehabilitation and Chronic Care'' determined the overall scope of this statement through consensus. Focused literature reviews were conducted in key topic areas and the final content of this Statement was agreed upon by all members. The current knowledge regarding physical activity in COPD is presented, including the definition of physical activity, the consequences of physical inactivity on lung function decline and COPD incidence, physical activity assessment, prevalence of physical inactivity in COPD, clinical correlates of physical activity, effects of physical inactivity on hospitalisations and mortality, and treatment strategies to improve physical activity in patients with COPD. This Task Force identified multiple major areas of research that need to be addressed further in the coming years. These include, but are not limited to, the disease-modifying potential of increased physical activity, and to further understand how improvements in exercise capacity, dyspnoea and self-efficacy following interventions may translate into increased physical activity. The Task Force recommends that this ERS statement should be reviewed periodically (e.g. every 5-8 years). © 2014 ERS
