Published reports indicate that 2.5% of deaths in the Netherlands are the result of euthanasia or physician-assisted suicide. It is not known how many patients make these requests in the United States, but the issue has gained considerable attention, including that of the Supreme Court. The focus of the writing and discussion regarding the request to die has been on a patient's capacity. ⋯ A patient's request to die is a situation that requires the physician to engage in a dialogue to understand what the request means, including whether the request arises from a clinically significant depression or inadequately treated pain. This article outlines some of the thoughts and emotions that could underlie the patient's request to die. Recommendations are made regarding the role of the primary care physician and the role of the psychiatric consultant in the exploration of the meaning of the request.

Although concern over the risks of red blood cell transfusion has resulted in several practice guidelines for transfusion, lack of data regarding the physiological effects of anemia in humans has caused uncertainty regarding the blood hemoglobin (Hb) concentration requiring treatment. ⋯ Acute isovolemic reduction of blood Hb concentration to 50 g/L in conscious healthy resting humans does not produce evidence of inadequate systemic TO2, as assessed by lack of change of VO2 and plasma lactate concentration. Analysis of Holter readings suggests that at this Hb concentration in this resting healthy population, myocardial ischemia would occur infrequently.

The risks of blood transfusion have been studied extensively but the benefits and the hemoglobin concentration at which patients should receive a transfusion have not. ⋯ Perioperative transfusion in patients with hemoglobin levels 80 g/L (8.0 g/dL) or higher did not appear to influence the risk of 30- or 90-day mortality in this elderly population. At hemoglobin concentrations of less than 80 g/L (8.0 g/dL), 90.5% of patients received a transfusion, precluding further analysis of the association of transfusion and mortality.

Randomized Controlled Trial Clinical Trial
A prospective trial of risk factors for sulfonylurea-induced hypoglycemia in type 2 diabetes mellitus.
Retrospective studies have identified oral sulfonylureas, age, and fasting as major risk factors for hypoglycemia in patients with type 2 diabetes. Sulfonylureas may be withheld from elderly patients out of concern for hypoglycemia. ⋯ Fasting was well tolerated among these elderly patients with type 2 diabetes treated with sulfonylureas. Older age should not be considered a contraindication to sulfonylurea treatment for diabetes. Stimulation of epinephrine secretion at normal or elevated plasma glucose levels appears to be the primary mechanism of protection against hypoglycemia in this study.
