Improved outcomes are associated with the Awakening and Breathing Coordination, Delirium, and Early exercise/mobility bundle (ABCDE); however, implementation issues are common. As yet, no study has integrated the barriers to ABCDE to provide an overview of reasons for less successful efforts. The purpose of this review was to identify and catalog the barriers to ABCDE delivery based on a widely used implementation framework, and to provide a resource to guide clinicians in overcoming barriers to implementation. ⋯ We provide the first, to our knowledge, systematic differential diagnosis of barriers to ABCDE delivery, moving beyond the conventional focus on patient-level factors. Our analysis offers a differential diagnosis checklist for clinicians planning ABCDE implementation to improve patient care and outcomes.

Insomnia is the most prevalent sleep disorder in the United States and has high comorbidity with a number of cardiovascular diseases (CVDs). In the past decade, a number of observational studies have demonstrated an association between insomnia and incident cardiovascular disease (CVD) morbidity and mortality, including hypertension (HTN), coronary heart disease (CHD), and heart failure (HF). ⋯ Purported mechanisms likely relate to dysregulation of the hypothalamic-pituitary axis, increased sympathetic nervous system activity, and increased inflammation. This paper reviews the most recent studies of insomnia and CVD and the potential pathophysiological mechanisms underlying this relationship and highlights the need for randomized trials to further elucidate the nature of the relationship between insomnia and CVD.

Organizing Pneumonia in an Adult With Chronic Recurrent Noninfectious Osteomyelitis: A Case Report and Literature Review.
Chronic recurrent multifocal osteomyelitis (CRMO) is an idiopathic inflammatory disorder primarily of children and adolescents that is characterized by multifocal nonpyogenic relapsing and remitting inflammatory bone lesions. Pulmonary abnormalities are rarely associated with CRMO, with two reported cases of consolidation on chest CT that occurred in children. We present a case of organizing pneumonia in an adult patient with CRMO. The concurrent worsening of pulmonary and bone disease suggests that CRMO may be a rare cause of organizing pneumonia.

Airway eosinophilia is a hallmark of allergic asthma, and understanding mechanisms that promote increases in lung eosinophil numbers is important for effective pharmacotherapeutic development. It has become evident that expansion of hematopoietic compartments in the bone marrow (BM) promotes differentiation and trafficking of mature eosinophils to the airways. ⋯ In addition, hematopoietic progenitor cells in the airways can respond to locally derived alarmins to produce a panoply of cytokines, thereby themselves acting as effector proinflammatory cells that potentiate type 2 responses in eosinophilic asthma. In this review, we provide evidence for these findings and discuss novel targets for modulating eosinophilopoietic processes, migration, and effector function of precursor cells.

Social media sites such as Twitter can significantly enhance education and advocacy efforts. In 2013, the American College of Chest Physicians (CHEST) launched a Twitter chat series using the hashtag #pulmcc to educate and advocate for topics related to pulmonary, critical care, and sleep medicine. ⋯ Twitter chats can be a powerful tool for the widespread engagement of a medical audience.
