BACKGROUND AND PURPOSE: Prophylactic anticonvulsants are routinely prescribed in the acute setting for intracerebral hemorrhage (ICH) patients, but some studies have reported an association with worse outcomes. We sought to characterize the prevalence and predictors of prophylactic anticonvulsant administration after ICH as well as guideline adherence. We also sought to determine whether prophylactic anticonvulsants were independently associated with poor outcome. METHODS: We performed a retrospective study of primary ICH in our two academic centers...

BACKGROUND: Recombinant factor VIIa (rFVIIa) is routinely used as an off-label hemostatic agent in children undergoing cardiac surgery. Despite evidence that rFVIIa use is associated with an increased incidence of thrombotic complications in adult cardiac surgery, the safety of rFVIIa as a rescue hemostatic agent in the pediatric cardiac surgical population is less definitively delineated. In this retrospective study, we used propensity score matching to compare the incidence of thrombotic complications between children treated with rFVIIa and their matched controls...

BACKGROUND: The intermediate group of patients with heart failure (HF) and mid-range left ventricular ejection fraction (HFmrEF) may constitute a specific phenotype, but a direct evidence is lacking. This study aimed to know whether this HF category is accompanied by a particular clinical phenotype and prognosis. METHODS AND RESULTS: This study includes 3446 ambulatory patients with chronic HF from two national registries. According to EF at enrollment, patients were classified as reduced (HFrEF, <40%), mid-range (HFmrEF, 40-49%) or preserved (HFpEF, ≥50%)...

PURPOSE: The dynamic intraligamentary stabilization (DIS) technique is based on a different treatment approach than ACL reconstruction in that it intends to promote self-healing of the ligament. It is only recommended for acute injuries (<21days). The purpose of the present study was to compare DIS and ACLR with respect to the extent of work incapacity, revision rates, secondary arthroscopies, and treatment costs during recovery. METHODS: The study was a post-hoc analysis of prospectively collected data in the Swiss National Accident Insurance Fund (SUVA) database...

BACKGROUND & AIM: Statin decreased the risk of decompensation and mortality in veteran patients with cirrhosis due to hepatitis C virus (HCV). Whether this beneficial effect can be extended to cirrhosis in general population or cirrhosis with other causes, such as hepatitis B virus (HBV) infection and alcohol, remains unknown. Statin also decreased the risk of hepatocellular carcinoma (HCC) in patients with chronic HBV and HCV infection. It is unclear whether the effect can be observed in patients already with cirrhosis...
