Background: Limited data are available regarding the direct comparison of angiographic and clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) for chronic total occlusion (CTO). Methods and Results: A prospective, randomized, multicenter trial was conducted to evaluate the non-inferiority of a zotarolimus-eluting stent (ZES; Endeavor Sprint®, n=80) to a sirolimus-eluting stent (SES; Cypher®, n=80) in patients with CTO lesion with a reference vessel diameter ≥2.5mm. The primary endpoint was in-segment binary restenosis rate at 9-month angiographic follow-up. Key secondary endpoints included target vessel failure (TVF; including cardiac death, myocardial infarction, and target vessel revascularization) and Academic Research Consortium-defined definite/probable stent thrombosis (ST) within 12 months. The ZES was non-inferior to the SES with respect to the primary endpoint, which occurred in 14.1% (95% confidence interval [CI]: 6.0-22.2) and in 13.7% (95%CI: 5.8-21.6) of patients, respectively (non-inferiority margin, 15.0%; P for non-inferiority <0.001). There were no significant between-group differences in the rate of TVF (10.0% vs. 17.5%; P=0.168) nor in the rate of ST (0.0% vs. 1.3%; P=0.316) during the 12-month clinical follow-up. Conclusions: The effectiveness and safety of ZES are similar to those of SES and therefore it is a good treatment option in patients undergoing PCI for CTO with DESs. Source

The purpose of this paper is to show the clinical and radiologic features of a variety of diffuse, infiltrative breast lesions, as well to review the relevant literature. Radiologists must be familiar with the various conditions that can diffusely involve the breast, including normal physiologic changes, benign disease and malignant neoplasm. Source

Background and purpose: Although abnormal sleep duration is positively associated with increased risk for cardiovascular disease and mortality, the specific impact on intracerebral haemorrhage (ICH) risk remains unclear. The relationship between sleep duration and the risk of ICH was investigated in our study. Methods: A nationwide, multicentre matched case-control study was performed to investigate the risk factors for haemorrhagic stroke, using patients from 33 hospitals in Korea. In all, 490 patients with ICH and 980 age- and sex-matched controls were enrolled. Detailed information regarding sleep, sociodemographic factors, lifestyle and medical history before ICH onset was obtained using qualified structured questionnaires. Sleep duration was categorized and the adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using a conditional logistic regression with 7 h as the reference duration. Results: The number of subjects with long sleep duration, more than 8 h, was significantly greater in the ICH group than in the control group (≥8 h, 30.4% vs. 22.6%, P = 0.002). After controlling for relevant confounding factors, longer sleep duration was found to be independently associated with the risk of ICH in a dose-response manner (8 h, OR 1.57, 95% CI 1.00-2.47; ≥9 h, OR 5.00, 95% CI 2.18-11.47). Conclusions: Our study suggested that long sleep duration is positively associated with an increased ICH risk in a dose-dependent manner. Further studies on the relationship linking long sleep duration with increased risk of ICH are required. © 2016 European Academy of Neurology. Source

The present study is aimed to exploring whether some single nucleotide polymorphisms (SNPs) within GRIA1, GRIA2 and GRIA4 could be associated with major depressive disorder (MDD) and whether they could predict clinical outcomes in Korean in-patients, respectively, treated with antidepressants. One hundred forty-five (145) patients with MDD and 170 healthy controls were genotyped for 17 SNPs within GRIA1, GRIA2 and GRIA4. Baseline and final clinical measures, including the Montgomery-Asberg Depression Rating Scale (MADRS) for patients with MDD, were recorded.No association was observed between alleles, genotypes and haplotypes under investigation and clinical and demographical variables. As a secondary finding, a marginal association was observed between rs4302506 and rs4403097 alleles within GRIA2 and age of onset in patients with MDD. Our findings provide evidence for a possible association between rs4302506 and rs4403097 SNPs and age of onset in patients withMDD. However, taking into account that the several limitations of our study including the moderately small sample size of our study, our findings should be considered with caution and further research is needed to draw more definitive conclusions. © Springer-Verlag 2011.

PURPOSE. To evaluate the effect of the Honan intraocular pressure reducer (HIPR) on vitreous reflux during intravitreal (IVT) injection. METHODS. Prospective, comparative, controlled, investigator-blinded, randomized clinical study. Sixty eyes of 60 patients who underwent IVT injection were allocated into 2 groups with or without using the HIPR. Vitreous reflux was estimated by measuring largest diameter of the conjunctival bleb formed after IVT injection. Preoperative intraocular pressure (IOP) before and after application of the HIPR and IOP immediately postoperatively and 3 and 10 minutes postoperatively were evaluated. RESULTS. The mean amount of vitreous reflux was significantly less with the HIPR than without the HIPR (1.46±1.04 mm vs 2.61±1.37 mm; p<0.001). The preoperative IOP was significantly lower with the HIPR than without the HIPR (11.62±4.04 mmHg vs 16.26±3.86 mmHg; p=0.026). The 3-minute postoperative IOP was 31.34±3.16 mmHg with the HIPR and 32.61±5.62 mmHg without the HIPR (no statistical significance; p=0.345). CONCLUSIONS. The HIPR prevents vitreous reflux after IVT through a reduction in the preoperative IOP. However, the HIPR appears not to affect the postoperative course of transient IOP elevation. © 2011 Wichtig Editore. Source
