Randomized Controlled Trial Clinical Trial
Glycemic control with glyburide/metformin tablets in combination with rosiglitazone in patients with type 2 diabetes: a randomized, double-blind trial.
To assess the efficacy and safety of adding rosiglitazone to an established regimen of glyburide/metformin in patients with type 2 diabetes who had not achieved adequate glycemic control (glycosylated hemoglobin [HbA1C] levels >7.0% and < or =10.0%). ⋯ In patients with inadequate glycemic control despite established glyburide/metformin therapy, the addition of rosiglitazone improves glycemic control, allowing more patients to achieve an HbA1C level <7% and perhaps delaying the need for insulin treatment.

Randomized Controlled Trial Clinical Trial
Addition of pioglitazone or bedtime insulin to maximal doses of sulfonylurea and metformin in type 2 diabetes patients with poor glucose control: a prospective, randomized trial.
To compare the efficacy of adding pioglitazone or bedtime isophane (NPH) insulin to maximal doses of metformin and an insulin secretagogue in patients with poor glucose control. ⋯ Adding pioglitazone or bedtime insulin for 16 weeks improved glycemic control in type 2 diabetic patients with secondary oral agent failure. Pioglitazone was associated with less hypoglycemia and improved HDL cholesterol levels.

Randomized Controlled Trial Multicenter Study Clinical Trial
Effects of sustained-release bupropion among persons interested in reducing but not quitting smoking.
To determine whether sustained-release bupropion promotes smoking reduction leading to smoking cessation among persons who wish to reduce their amount of smoking, but who are unwilling to quit or who perceive themselves as being unable to quit. ⋯ Sustained-release bupropion, when used in smokers initially not willing to make a cessation attempt, can help sustain smoking reduction while subjects are on active medication, reduce the time until the next cessation attempt, and increase short-term abstinence rates. However, these benefits were modest and not sustained after bupropion was discontinued.

Randomized Controlled Trial Clinical Trial
Antibiotic-coated hemodialysis catheters for the prevention of vascular catheter-related infections: a prospective, randomized study.
To determine the efficacy of minocycline-rifampin-coated hemodialysis catheters in reducing catheter-related infections in patients requiring hemodialysis for acute renal failure. ⋯ The use of polyurethane hemodialysis catheters impregnated with minocycline and rifampin decreases the risk of catheter-related infection in patients with acute renal failure.

Randomized Controlled Trial Comparative Study Clinical Trial
A prospective randomized comparison of loop recorders versus Holter monitors in patients with syncope or presyncope.
The initial management of syncope or presyncope typically involves short-term cardiac monitoring using a Holter monitor. A loop recorder is used to extend the period of monitoring to increase the probability of obtaining a symptom-rhythm correlation. Loop recorders and Holter monitors are both used commonly, but their utility has not been compared prospectively. ⋯ Loop recorders have a much higher diagnostic yield for patients with syncope or presyncope as compared with Holter monitors. The utility of loop recorders is limited by some patients' inability to operate them correctly.
