BACKGROUND Contrast-induced acute kidney injury (CI-AKI) after percutaneous coronary intervention is associated with adverse short- and long-term outcomes. However, identification of patients at risk for CI-AKI is challenging. Using a large contemporary randomized trial database of patients with ST-segment-elevation myocardial infarction, we therefore sought to examine whether admission B-type ...

BACKGROUND Contrast-induced nephropathy (CIN) is associated with poor outcomes in patients with acute myocardial infarction. However, the predictors of CIN have yet to be fully elucidated. METHODS AND RESULTS The study included 273 consecutive patients with a first-time ST-segment elevation myocardial infarction who underwent reperfusion within 12 hours of symptom onset. The exclusion criteri...

BACKGROUND Few studies compared the efficacy of theophylline with N-acetylcysteine or evaluated the efficacy of combination therapy in the prevention of contrast-induced nephropathy (CIN). We compared the efficacy of theophylline, N-acetylcysteine, and the combination of these agents in the prevention of CIN. METHODS This randomized controlled trial was conducted on 96 patients referring cons...

Objective Epilepsy is reported in 15-90% of the children with Cerebral Palsy (CP) but its clinical course is not well defined.

the estimation of instantaneous peak discharge is important for watershed management because there is ainsufficient climatic and hydrologic data in countries such as iran. researchers have been forced to link constantparameters (geomorphology) and variable parameters (hydrology) to models with minimum dependence on climaticand hydrologic data for hydrologic estimation. the present study used a ...
