Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
The Effects of cyclooxygenase-2 inhibitors and nonsteroidal anti-inflammatory therapy on 24-hour blood pressure in patients with hypertension, osteoarthritis, and type 2 diabetes mellitus.
Nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase-2 (COX-2) inhibitors may attenuate the efficacy of antihypertensive agents in high-risk patients. Therefore, we conducted a double-blind, randomized trial to evaluate the effects of celecoxib, rofecoxib, and naproxen on 24-hour blood pressure (BP) in patients with type 2 diabetes, hypertension, and osteoarthritis. ⋯ At equally effective doses for osteoarthritis management, treatment with rofecoxib but not celecoxib or naproxen induced a significant increase in 24-hour systolic BP. However, destabilization of hypertension control occurred to some extent in all 3 treatment groups; this phenomenon was seen more often in patients treated with rofecoxib than with the other therapies.

Comparative Study
Prevalence of abnormal glucose tolerance following a transient ischemic attack or ischemic stroke.
Despite current preventive therapies, patients with transient ischemic attack (TIA) and ischemic stroke remain at high risk for recurrent brain disease and cardiovascular events. In an effort to develop new therapies, abnormal glucose tolerance has recently been proposed as an interventional target. Among persons not otherwise known to be diabetic, impaired glucose tolerance (IGT) and diabetic glucose tolerance (DGT) are each associated with an increased risk for incident vascular disease, vascular disease mortality, and all-cause mortality. We conducted this study to determine if IGT and DGT are sufficiently common among patients with TIA and ischemic stroke to warrant therapeutic trials of antihyperglycemic agents. ⋯ Impaired glucose tolerance and DGT are present in most persons with a recent TIA or ischemic stroke who have no history of diabetes and a fasting plasma glucose level less than 126 mg/dL (<7.0 mmol / L). Our findings bring new urgency to the initiation of research to examine the effectiveness of antihyperglycemic therapies among patients with cerebrovascular disease and abnormal glucose tolerance.

Recent evidence indicates that most older persons who develop disability in their activities of daily living (ADLs) regain independent function, but many of these persons subsequently experience recurrent disability. The aims of this study were to identify independent predictors of time to and duration of recovery of independent ADL function among newly disabled community-dwelling older persons. ⋯ Habitual physical activity is an independent predictor of time to and duration of recovery of independent ADL function among newly disabled community-dwelling older persons. Because the other independent predictors for time to recovery differ from those for maintenance of recovery, different mechanisms may underlie these 2 recovery outcomes, suggesting that different interventions may be required to promote recovery than to maintain independent ADL function after recovery.
