To evaluate the effect of triamcinolone acetonide (ITA) on intraocular pressure (IOP) following intravitreal injection, and, in those patients who experience post-injection elevation of IOP, to determine the time course, effect of multiple injections, and risk factors for the pressure rise. ⋯ ITA is frequently associated with a significant elevation in IOP, typically within the first 2-months after injection. Most patients who do not have an elevated IOP after an initial injection will not experience a pressure rise after an additional one. About one-third will require topical glaucoma therapy for IOP control. Patients with OAG may be more difficult to control and require a longer duration of therapy. The inconsistent post-injection follow-up visit intervals among patients in this retrospective review may have affected our results, as some patients with maximum IOP changes may have been missed between office visits. In addition, practice patterns among treating physicians typically differ as to thresholds for the treatment of elevated IOP. A randomized, prospective, controlled trial could better address these issues.

Duloxetine is a serotonergic noradrenergic reuptake inhibitor with demonstrated efficacy in each of three independent studies for treatment of adults with generalized anxiety disorder (GAD). A pooled dataset from all completed trials is provided here to show the most likely clinical outcomes associated with duloxetine treatment for GAD. ⋯ In this sample of more than 1100 patients, duloxetine was efficacious for reducing anxiety severity and for increasing patients' overall role functioning in GAD.

Randomized Controlled Trial Multicenter Study Comparative Study
A randomized, controlled trial comparing darbepoetin alfa correction/maintenance dosing with weekly dosing for treating chemotherapy-induced anemia.
To evaluate if a darbepoetin alfa correction/maintenance dosing regimen is non-inferior to a weekly regimen with respect to red blood cell transfusion requirements in patients with chemotherapy-induced anemia (CIA). ⋯ A correction/maintenance schedule with its initial two-fold higher weekly dosing and subsequent Q3W dosing yielded outcomes similar to those observed with a weekly schedule. Although correction/maintenance dosing provided no incremental clinical benefit, Q3W dosing could provide benefits of convenience and facilitate patient compliance.

Meta Analysis Comparative Study
The development of new-onset type 2 diabetes associated with choosing a calcium channel blocker compared to a diuretic or beta-blocker.
It has been acknowledged that patients who receive a beta-blocker or diuretic based regimen are at increased risk of developing new-onset diabetes. Recently, angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) have been shown to decrease patients' odds of developing new-onset type 2 diabetes. A number of large placebo-controlled multi-center trials in post-myocardial infarction and heart failure patients have shown the ability of renin-angiotensin-aldosterone system medications to reduce the onset of type 2 diabetes. Pharmacologic data has shown improved insulin sensitivity with ACEIs and ARBs. Controversy persists regarding the influence of calcium channel blockers on the development of new-onset diabetes. ⋯ Calcium channel blockers may be associated with reduced odds of developing new-onset type 2 diabetes compared to diuretics and beta-blockers.

Randomized Controlled Trial Multicenter Study
Once-daily sitagliptin, a dipeptidyl peptidase-4 inhibitor, for the treatment of patients with type 2 diabetes.
Sitagliptin, an oral, potent, and selective dipeptidyl peptidase-4 (DPP-4) inhibitor was evaluated as once-daily monotherapy in a 12-week randomized, double-blind, placebo-controlled, parallel group, dose-ranging study. Additionally, the glycemic response to sitagliptin 100 mg daily was evaluated as a once-daily (100 mg once-daily) or twice-daily (50 mg twice-daily) dosing regimen. ⋯ Sitagliptin monotherapy improved indices of glycemic control compared to placebo and was generally well-tolerated in patients with type 2 diabetes. The glycemic response to treatment with sitagliptin 100 mg/day was similar between the sitagliptin 100-mg once-daily and 50-mg twice-daily dose regimens.
