Randomized Controlled Trial Clinical Trial
Short- and long-term effects of outpatient rehabilitation in patients with chronic obstructive pulmonary disease: a randomized trial.
Pulmonary rehabilitation programs are effective in patients with severe chronic obstructive pulmonary disease (COPD) in the short term, but their long-term effects are not known. We investigated the short- and long-term effects of a 6-month outpatient rehabilitation program in patients with severe COPD. ⋯ Among patients who completed the 6-month program, outpatient training resulted in significant and clinically relevant changes in 6-minute walking distance, maximal exercise performance, peripheral and respiratory muscle strength, and quality of life. Most of these effects persisted 18 months after starting the program.

We sought to determine whether illness severity and anticipated level of function, as evaluated at the time of admission, were associated with outcomes and costs of care for patients admitted to the medical service. ⋯ Physicians' estimates of patients' illness severity and anticipated function at the time of discharge, as made by interns using a system designed to help them sign out to their colleagues, predict outcomes and costs of hospitalization. Such a system may be useful in developing new approaches to management strategies based on prognosis.

The major risk of therapy with platelet glycoprotein IIb/IIIa receptor inhibitors is bleeding. We reviewed trials using these agents to determine if bleeding risks include an increased incidence of intracranial hemorrhage. ⋯ Intravenous glycoprotein IIb/IIIa receptor inhibitors alone or in combination with heparin do not cause a statistically significant excess of intracranial hemorrhage as compared with heparin alone. Because of small numbers, the data do not exclude the possibility of an excess of intracranial hemorrhage in some groups of patients treated with glycoprotein IIb/IIIa receptor inhibitors.

To examine whether the size of the effusion, the presence of tamponade, and inflammatory signs are useful in determining the causes of moderate or severe pericardial effusions. ⋯ In many patients, pericardial effusions are due to a known underlying disease or condition. In patients without underlying diseases, inflammatory signs, the size of effusion, and the presence or absence of cardiac tamponade can be helpful in establishing cause.
