To determine whether elderly patients with protein-energy undernutrition at admission are at increased risk for subsequent life-threatening events after controlling for illness severity. ⋯ There is a complex interrelationship between nutritional status, illness severity, and clinical outcomes among the hospitalized elderly. The serum secretory proteins and cholesterol are correlated with other indicators of illness severity and adverse outcomes, but may not be good markers of nutritional risk. In contrast, weight loss, a low body mass index, and other indicators of lean and fat mass depletion appear to place the patient at increased risk for adverse outcomes independent of illness severity. Whether it is possible to reverse such established nutritional deficits and reduce complication risk in the acute care setting remains to be determined.

Hypertensive urgencies and emergencies are common clinical occurrences in hypertensive patients. Treatment practices vary considerably to because of the lack of evidence supporting the use of one therapeutic agent over another. This paper was designed to review the evidence for various pharmacotherapeutic regimens in the management of hypertensive urgencies and emergencies, in terms of the agents' abilities to reach predetermined "safe" goal blood pressures (BPs), and to prevent adverse events. ⋯ Many effective agents exist for the treatment of hypertensive crises. Because of the lack of large randomized controlled trials, many questions remain unanswered, such as follow-up times and whether any of the studied agents have mortality benefit.

Greater participation in medical decision making is generally advocated for patients, and often advocated for those with diabetes. Although some studies suggest that diabetic patients prefer to participate less in decision making than do healthy patients, the empirical relationship between such participation and diabetic patients' satisfaction with their care is currently unknown. We sought to characterize the relationship between aspects of diabetic patients' participation in medical decision making and their satisfaction with care. ⋯ Clinicians may feel reassured that encouraging even initially reluctant patients with diabetes to participate in medical decision making may be associated with increased patient satisfaction. Greater patient participation has the potential to improve diabetic self-care because of the likely positive effect of patient satisfaction on adherence to treatment. Further research to assess the prospective effects of enhancing physician facilitation of patient participation is likely to yield important information for the effective treatment of chronically ill patients.

The central venous pressure (CVP) is commonly estimated at the bedside by measuring the height of the jugular venous pressure (JVP) relative to the sternal angle. Determining the CVP from this measure requires that the distance from the sternal angle to the level of the mid-right atrium be known. Classical clinical teaching quotes this distance as 5 cm, invariable between patients, and invariable with changes in the elevation of the patient's head. The validity of these JVP characteristics has been questioned. ⋯ The distance from the sternal angle to the level of the mid-right atrium varies considerably between individuals and with patient position. When using the JVP to calculate the CVP, physicians need to consider specific patient factors and the patient's position.

Comparative Study
Black-white differences in severity of coronary artery disease among individuals with acute coronary syndromes.
To determine whether the extent of coronary obstructive disease is similar among black and white patients with acute coronary syndromes. ⋯ Black veterans who present with acute coronary insufficiency are less likely than whites to have significant coronary obstruction. Current understanding of coronary disease does not provide an explanation for these differences.
