The purpose of this review is to critique and summarize clinical literature relevant to thromboprophylaxis in critically ill patients with renal insufficiency. The specific objectives are to discuss factors that increase the risks for bleeding and venous thromboembolism in critically ill patients, with a focus on patients with renal insufficiency, and to consider prophylaxis management options and the rationale for their use. ⋯ We provide some considerations for practice in the conclusion section.

The clinical role of emerging imaging technologies for diagnosing cardiac sarcoidosis and other cardiomyopathies is evolving. An up-to-date review of the role of various imaging modalities in the evaluation of cardiac sarcoidosis and other cardiomyopathies is presented. ⋯ Clinical and subclinical cardiac involvement is common among patients with sarcoidosis. A structured clinical assessment incorporating advanced cardiac imaging with CMR and FDG-PET scanning is more sensitive than the established clinical criteria. CMR is an established imaging modality in the diagnosis of various other cardiomyopathies. Well designed prospective clinical trials are awaited to define the exact role of these imaging studies in the diagnosis and guidance of therapy.

Sampling the detachable cells and acellular lining secretions of the human respiratory tract by bronchoalveolar lavage (BAL) is a means of obtaining relevant components from the airways and alveolar areas for research use and clinical analysis in normals (controls) and patients with a wide spectrum of interstitial lung diseases (ILDs). This review attempts to discuss recent findings from BAL studies that provide insight into pathogenic mechanisms of ILDs and/or assist in diagnosing disease activity. ⋯ Whereas BAL findings continue to impact on understanding disease pathogenesis and this may be its major use now, BAL fluid components, cells in particular, are not correlated well with activity of disease nor for monitoring disease progress or response to treatment. For a few rarer ILDs, BAL fluid characteristics may strongly support a diagnosis.

This review aims to highlight and place in context recent advances in and insights into the natural history, diagnosis, and management of idiopathic pulmonary fibrosis (IPF). ⋯ Although IPF remains a diagnostic and therapeutic challenge to even the most experienced of clinicians, our knowledge of the natural history of the disease, diagnostic accuracy, and therapeutic approach continue to advance.
