Objectives: Experimental evidence has indicated the benefit of simvastatin in the treatment of subarachnoid hemorrhage (SAH). Recently, acute simvastatin treatment was not shown to be beneficial in neurological outcome using modified Rankin Scale. Cognitive function is another important dimension of outcome assessment and yet had not been investigated in statin studies for aneurysmal subarachnoid hemorrhage. We therefore explored whether acute simvastatin treatment would improve cognitive outcomes., Methods: The study recruited SAH patients with acute simvastatin treatment enrolled in a randomized controlled double-blinded clinical trial (ClinicalTrials.gov Identifier: NCT01038193). A control cohort of SAH patients without simvastatin treatment was identified with propensity score matching of age and admission grade. Primary outcome measure was Montreal Cognitive Assessment (MoCA). Secondary outcome measures were delayed ischaemic deficit (DID), delayed cerebral infarction, modified Rankin Scale (mRS), and Mini-Mental State Examination (MMSE)., Results: Fifty-one SAH patients with acute simvastatin treatment and 51 SAH patients without simvastatin treatment were recruited for analysis. At 3 months, there were no differences in MoCA scores (MoCA: 21+/-6 vs. 21+/-5, p=0.772). MoCA-assessed cognitive impairment (MoCA<26) was not different (75% vs. 80%, OR 0.7, 95%CI 0.3 to 1.8, p=0.477). There were also no differences in DID, delayed cerebral infarction, favorable mRS outcome, and MMSE scores, and MMSE-assessed cognitive impairment between both groups., Conclusions: The current study does not support that acute simvastatin treatment improves cognitive outcome after aneurysmal subarachnoid hemorrhage., (Copyright © 2015 Elsevier B.V.

Objectives: The role of serum α-fetoprotein (AFP) measurements in the diagnosis of hepatocellular carcinoma (HCC) remains controversial. Some guidelines have advised against the use of AFP in the diagnosis of HCC. This study was conducted to evaluate the performance of AFP in the diagnosis of HCC, and to identify the optimal cut-off value of serum AFP in the diagnosis of HCC in patients with a hepatic mass., Methods: Patients who presented during the period from May 1997 to March 2003 with hepatic lesions, for whom paired data on serum AFP values at baseline and lesion histology were available, were reviewed. The performance of AFP in the diagnosis of HCC was determined using receiver operating characteristic curve analysis., Results: Data for a total of 805 patients were evaluated. The mean AFP value was 26,900 ng/ml (range: 0-1,965,461 ng/ml). The histological diagnosis was HCC in 557 patients. The optimal AFP cut-off value was 10 ng/ml (for sensitivity of 82.6% and specificity of 70.4%). At a cut-off level of 200 ng/ml, sensitivity, specificity, and positive and negative predictive values were 47.7%, 97.1%, 97.5% and 44.4%, respectively. The diagnostic performance of AFP remains similar in patients with chronic hepatitis B virus infection, despite a lower negative predictive value. Common aetiologies of liver lesions associated with elevated AFP include cholangiocarcinoma and neuroendocrine tumours., Conclusions: In Asian patients with suspicious liver lesions, the cut-off AFP level of 200 ng/ml is useful to achieve a diagnosis of HCC with high specificity and reasonable sensitivity. The measurement of serum AFP should not be excluded from guidelines for the diagnosis of HCC., (© 2013 International Hepato-Pancreato-Biliary Association.)
