Did We Finally Slay the Evil Dragon of Cigarette Smoking in the Late 20th Century?: Unfortunately, the Answer Is No-the Dragon Is Still Alive and Well in the 21st Century and Living in the Third World. Shame on Us!
If cigarettes were introduced as a new consumer product today, it is unlikely they would receive government regulatory approval. Cigarettes have proven biologic toxicities (carcinogenesis, atherogenesis, teratogenesis) and well-established causal links to human disease. Things were very different in 1913 when the R. ⋯ There is some good news. The 2003 Framework Convention on Tobacco Control, supported strongly by the American College of Chest Physicians, is the first global public health treaty of the new millennium. Many developed societies have begun planning to rid their countries of cigarettes in what is called the Endgame Strategy, and now is the time for the international medical community to help change tobacco policy to a worldwide endgame approach to rid all humanity of smoking-related diseases.

Review Meta Analysis
Prognostic value of plasma Heart-type Fatty Acid Binding Protein in patients with acute Pulmonary Embolism: a Meta-analysis.
Several studies have described heart-type fatty acid-binding protein (H-FABP) from early blood samples as a predictor of outcome in acute pulmonary embolism (PE). This systematic review is designed to determine the prognostic value of H-FABP aimed for use in patients with acute PE. ⋯ H-FABP is associated with an increased risk of mortality or complicated clinical events in patients with acute PE across different studies with a high degree of clinical and methodologic diversity. The result suggests that H-FABP has significant prognostic value for acute PE.

Critical care practitioners must frequently make decisions about their patients' ability to swallow food, liquids, and pills. These decisions can be particularly difficult given the incompletely defined epidemiology, diagnostic criteria, and prognostic features of swallowing disorders in critically ill patients. Furthermore, the consequences of improper decisions-namely, aspiration, malnutrition, hunger, and thirst-can be devastating to patients and their families. ⋯ Next, we describe the different diagnostic tests for swallowing dysfunction and describe a general approach to the initial assessment for swallowing disorders. Finally, we explore the existing treatments for swallowing dysfunction. Given the burden of swallowing dysfunction in patients recovering from critical illness, enabling critical care practitioners to manage these disorders, while stimulating new investigation into their pathophysiology, diagnosis, and management, will enhance our care of critically ill patients.

Efforts to answer the question of whether or when physicians may unilaterally refuse to provide treatments they deem medically futile, but that are nonetheless demanded by patients or their surrogates, have been characterized as intractable failures. We propose a new look at this old problem and suggest reframing the debate in terms of the implicit social contract, in healthy democracies, between the medical profession and the society it serves. This ever-evolving contract is predicated upon providing patients with beneficial and desired medical care within the constraints of scarce resources and the characteristics of our health-care system. ⋯ Between these two poles lies a contentious gray area, where the rights and obligations of patients and physicians are being shaped continuously by the many forces that are at play in a democratic society, including professional guidelines, social advocacy, legislation, and litigation. We provide examples of how this gray area has been and is negotiated around rights to refuse and demand a variety of life-sustaining treatments, and anticipate conflicts likely to arise in the future. Reframing the futility debate in this way reveals that the issue is not a story of intractable failure, but rather, a successful narrative about how democracies balance the legitimate perspectives of patients and physicians against a backdrop of societal constraints and values.

Smoking and OSA are widely prevalent and are associated with significant morbidity and mortality. It has been hypothesized that each of these conditions adversely affects the other, leading to increased comorbidity while altering the efficacy of existing therapies. However, while the association between smoking and OSA is plausible, the evidence is less than conclusive. ⋯ Smoking cessation should improve OSA, but the evidence to support this is also limited. This article reviews the current evidence linking both conditions and the efficacy of various treatments. Limitations of the current evidence and areas in need of future investigation are also addressed.
