Review Meta Analysis
A systematic review and meta-analysis of studies comparing readmission rates and mortality rates in patients with heart failure.
Heart failure is the leading cause of hospitalization and readmission in many hospitals worldwide. We performed a meta-analysis to evaluate the effectiveness of multidisciplinary heart failure management programs on hospital admission rates. ⋯ This systematic review suggests that specific heart failure-targeted interventions significantly decrease hospital readmissions but do not affect mortality rates.

Meta Analysis Comparative Study
A meta-analysis comparing the effect of thiazolidinediones on cardiovascular risk factors.
In patients with type 2 diabetes mellitus, all therapeutic options should be evaluated for their effect on cardiovascular risk factors, in addition to glycemic control. We conducted a meta-analysis of randomized controlled trials of pioglitazone hydrochloride and rosiglitazone maleate in patients with type 2 diabetes to evaluate their effect on glycemic control, lipids, blood pressure, and weight. ⋯ Thiazolidinediones have similar effects on glycemic control and body weight. Pioglitazone produced a more favorable lipid profile. Head-to-head comparative trials as well as longer-term cardiovascular outcome studies are needed to determine whether there are differences in efficacy between the 2 thiazolidinediones.

Meta Analysis
Insulin therapy for critically ill hospitalized patients: a meta-analysis of randomized controlled trials.
Hyperglycemia is common in critically ill hospitalized patients, and it is associated with adverse outcomes, including increased mortality. The objective of this meta-analysis was to determine the effect of insulin therapy initiated during hospitalization on mortality in adult patients with a critical illness. ⋯ Insulin therapy initiated in the hospital in critically ill patients has a beneficial effect on short-term mortality in different clinical settings.

Meta Analysis
Using the coronary artery calcium score to predict coronary heart disease events: a systematic review and meta-analysis.
Primary prevention of coronary heart disease is most appropriate for patients at relatively high risk. Measurement of coronary artery calcium has been proposed as a way to improve risk assessment, but it is unknown whether it adds predictive information to standard risk factor assessment. ⋯ The coronary artery calcium score is an independent predictor of coronary heart disease events.

Heparin-induced thrombocytopenia (HIT) is a serious complication of heparin therapy that has a high rate of morbidity (thrombosis and amputation) and mortality. In the past, a number of different anticoagulants have been used to treat HIT in an attempt to prevent these complications. More recently, direct thrombin inhibitors have become popular. This systematic review summarizes the risk for thrombosis in HIT patients when heparin therapy is stopped; evidence of the efficacy of thrombin inhibitors in patients with HIT with and without thrombosis; evidence supporting the use of thrombin inhibitors in patients with a history of HIT who require a coronary intervention procedure; and the risk for bleeding when antithrombotic agents are used.
