For stroke prevention in patients with atrial fibrillation and other indications new oral anticoagulants have been developed. These drugs are direct anticoagulants in contrast to the indirectly acting vitamin-K antagonists, which are used for decades as the only available drugs. ⋯ However, to transfer the benefit from the large scale studies to the real world conditions, physicians have to get clinical experience in using the new drugs. Especially drug interactions, impaired renal function and periinterventional bridging need special attention to ensure transfer of the new drugs benefits to daily life treatment.

ReviewHigh-Resolution CT of Interstitial Lung Disease: A Continuous Evolution.
Before the advent of high-resolution computed tomography (HRCT), the role of imaging, chest radiography in particular, in the management of patients with interstitial lung disease was limited. In the past 25 years, this has radically changed. HRCT has transformed the diagnostic landscape by providing detailed cross-sectional imaging of the lungs, which permit ready identification of a variety of different interstitial lung diseases. ⋯ Recently, HRCT data have been integrated with pulmonary function in staging models to predict prognosis particularly in idiopathic fibrosing lung disease. This article reviews these stages of evolution. The emergence of the multidisciplinary approach to diagnosis will also be considered.

ReviewCritical care strategies to improve neurocognitive outcome in thoracic surgery.
This review focuses on neurocognitive outcome with respect to potential pathophysiological inflammatory mechanisms of thoracic surgery and one-lung ventilation, risk factors of postoperative delirium and postoperative cognitive dysfunction (POCD) as well as anti-inflammatory strategies. ⋯ There is evidence that important key strategies improve neurocognitive outcome after thoracic surgery. This includes adequate risk stratification, the anesthetic management and postoperative critical care strategies.

This article reviews the current diagnostic strategies for patients with suspected pulmonary embolism (PE) focusing on the current first choice imaging modality, computed tomographic pulmonary angiography (CTPA). Diagnostic strengths and weaknesses and associated cost-effectiveness of the diagnostic pathways will be discussed. The radiation dose risk of these pathways will be described and techniques to minimize dose will be reviewed. ⋯ Although current cost-effectiveness evaluations have established CT as integral in the PE diagnostic pathway, failure to acknowledge the impact of alternate diagnosis represents a current knowledge gap. The emerging dual energy capacity of current CT scanners offers the potential to evaluate both pulmonary vascular morphology and ventilation perfusion relationships within the lung parenchyma at high spatial resolution. This dual assessment of lung morphology and lung function at low (< 5 millisievert) radiation dose represents a substantial advance in PE imaging.

Computed tomography (CT) is the core imaging modality for the evaluation of thoracic disorders. With the recently developed dual-energy CT (DECT) technique, the clinical utility of CT in the management of pulmonary diseases can be expanded. The most actively investigated principle of dual energy is material decomposition based on attenuation differences at different energy levels. ⋯ The second major possibility offered by DECT is virtual monochromatic imaging that represents a new option for standard chest CT in daily routine. In this review, imaging principles and clinical applications of dual-energy thoracic CT are described. Knowledge of the applications of DECT may lead to wider use of this technique in the field of respiratory disorders.
