ReviewThe Terri Schiavo saga: ethical and legal aspects and implications for clinicians.
On March 31, 2005, Terri Schiavo (born December 3, 1963) died -- the final complication of a cardiac arrest on February 25, 1990. Her death was preceded by the withdrawal of artificially administered hydration and nutrition through a feeding tube. Prior to her death, Terri's saga was the focus of intense medical, ethical, and legal debates in the United States (US) and elsewhere. ⋯ Much of the confusion revolved around a number of ethical and legal questions including: Is it ethically and legally permissible to withhold or withdraw life-sustaining treatments from patients who do not want the treatments? Is withholding or withdrawing life-sustaining treatments the same as physician-assisted suicide or euthanasia? Is artificially administered hydration and nutrition a medical treatment or mandatory care akin to bathing? What were Terri's values, preferences, and goals regarding life-sustaining treatments? In this article, the medical, ethical, and legal data related to the case and the aforementioned ethical and legal questions raised by it are reviewed. Finally, the clinical implications of the saga, such as the need for clinicians to be more proactive in educating patients about their rights related to making health care decisions, end-of-life care options, and advance care planning (e.g., completing an advance directive) are discussed. Notably, given that the Schiavo saga occurred in the US, this article is written from a US perspective.

Comparative StudyAdditional spirometry criteria predict postoperative complications after coronary artery bypass grafting (CABG) independently of concomitant chronic obstructive pulmonary disease: when is off-pump CABG more beneficial?
Concomitant chronic obstructive pulmonary disease (COPD) is associated with an increased rate of post-coronary artery bypass grafting (CABG) complications. The ratio of forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC) <70%, proposed by the Global Initiative for Chronic Obstructive Lung Disease as a criterion for the diagnosis of COPD, is criticized for not considering physiological, age-related changes in lung function. ⋯ FEV1

2009 evidence-based clinical practice guidelines for diagnosing a first episode of lower extremities deep vein thrombosis in ambulatory outpatients.
The GRADE working group has recently suggested a rigorous framework for clinical practice guidelines (CPG) addressing diagnostic tests and test strategies based on the impact of alternative approaches on patient-important outcomes. The framework mandates explicit evidence summaries, ratings of the quality of evidence, and specifying recommendations as strong or weak. ⋯ We provide three groups of recommendations for clinicians practicing in settings with access to different types of D-dimer tests -- highly sensitive, moderately sensitive, and no availability of D-dimer. We consider the use of clinical prediction rules in guiding the diagnostic process, the potential for negative D-dimer or venous ultrasound (US) to rule out disease, and the role of follow-up testing (US following positive D-dimer result, D-dimer following negative US, and serial US) depending on the probability of DVT at the start of diagnostic process. We recommend the following: that clinicians without access to a highly or moderately sensitive D-dimer test rely on US to guide DVT diagnosis; that those with access use the highly sensitive D-dimer to determine, in patients with low or moderate probability of DVT (by the Wells rule) whether US is needed; that in patients with low pre-test probability (pre-TP) and a negative D-dimer (either highly or moderately sensitive) they follow patients without further testing; that in patients with high pre-test probability they perform a compression ultrasound without D-dimer testing.
