Perivascular fat attenuation for predicting adverse cardiac events in stable patients undergoing invasive coronary angiography

BackgroundInflammation surrounding the coronary arteries can be non-invasively assessed using pericoronary adipose tissue attenuation (PCAT). While PCAT holds promise for further risk stratification of patients with low coronary artery disease (CAD) prevalence, its value in higher risk populations remains unknown.MethodsCORE320 enrolled patients referred for invasive coronary angiography with known or suspected CAD. Coronary computed tomography angiography (CCTA) images were collected for 381 patients for whom clinical outcomes were assessed 5 years after enrollment. Using semi-automated image analysis software, PCAT was obtained and normalized for the right coronary (RCA), left anterior descending (LAD), and left circumflex arteries (LCx). The association between PCAT and major adverse cardiovascular events (MACE) during follow up was assessed using Cox regression models.ResultsThirty-seven patients were excluded due to technical failure. For the remaining 344 patients, median age was 62 (interquartile range, 55–68) with 59% having ≥1 coronary artery stenosis of ≥50% by quantitative coronary angiography. Mean attenuation values for PCAT in RCA, LAD, and LCx were ?74.9, ?74.2, and ?71.2, respectively. Hazard ratios and 95% confidence intervals (CI) for normalized PCAT in the RCA, LAD, and LCx for MACE were 0.96 (CI: 0.75–1.22, p ?= ?0.71), 1.31 (95% CI: 0.96–1.78, p ?= ?0.09), and 0.98 (95% CI: 0.78–1.22, p ?= ?0.84), respectively. For death, stroke, or myocardial infarction only, hazard ratios were 0.68 (0.44–1.07), 0.85 (0.56–1.29), and 0.57 (0.41–0.80), respectively.ConclusionsIn patients referred for invasive coronary angiography with suspected CAD, PCAT did not predict MACE during long term follow up. Further studies are needed to understand the relationship of PCAT with CAD risk.     

中文SCI科技期刊现状与影响力提升建议

【目的】 研究我国中文SCI科技期刊的现状,以期为其影响力提升和未来发展提供思考。【方法】 利用网站调研(期刊官网和Web of Science数据库等)、微信公众号运营情况查询及统计分析等方法对中文SCI科技期刊进行较全面的数据采集与分析。【结果】 18种中文SCI科技期刊有深厚的历史积淀和良好的发展基础,但整体上仍存在一些问题,如国内影响力不如优秀的纯中文期刊(国内影响力排名不够靠前),国际影响力不高(JCR分区仅为Q3或Q4区),国际化发展程度不够(国际编委占比为0的期刊高达11种,缺乏国际新媒体宣传),不够重视网络首发(仅9种期刊有网络首发)等。【结论】 在目前国内良好政策环境下,我国中文SCI科技期刊需要坚守初心,可根据各自期刊定位制定个性化发展策略,从而发展成为旗舰期刊甚至是世界一流期刊。     

Accurate detection of reemergent anti-donor ABO antibody is crucial for safe transfusion in ABO major incompatible HSCT patient after achieved the stages of full switch to donor type

Dynamic monitoring ABO chimera including erythroid ABO antigen and anti-A/B is crucial to not only assess the status of erythroid engraftment but also achieve personalized safety transfusion in patients post ABO incompatible hematopoietic stem cell transplantation. Transfusion support for ABO incompatible (ABOi) HSCT patients after achieved complete alteration to donor origin still remains cautious because the instant hematopoietic status on these transplant patients possibly returned to patient origin derived from early disease relapse and graft loss or failure. We reported that reemergent anti-B in a female patients (donor/patient: B/O) at the early phase after achievement complete donor type were not effectively found from partial automatic ABO blood grouping systems, which directly resulted in differential judgement of transplantation stage for about 15 days and disturbed the optimal recommendation on transfusion support. Meanwhile, the solely alteration of ABO chimera was found and earlier than changes of other markers such as MRD diagnosis, chimerism analysis by STR-PCR and sex chromosome assays, which can be an available predictors for bad transplant outcomes such as graft failure.

骨科大手术患者中医体质类型与静脉血栓栓塞症相关性研究

目的:探讨骨科大手术患者中医体质类型分布特点及其与静脉血栓栓塞症(VTE)的相关性。方法:选取220例骨科大手术患者,其中术后3个月内并发VTE患者102例为观察组,术后3个月内未发生VTE患者118例为对照组。对两组患者进行中医体质判定并分析。结果:220例骨科大手术患者中,平和质64例(29.09%),偏颇体质156例(70.91%)。骨科大手术患者最常见体质类型为气虚质、血瘀质、平和质。观察组最常见体质类型为气虚质、血瘀质,对照组最常见体质类型为平和质、气虚质。Logistic回归分析发现气虚质、血瘀质与VTE具有显著相关性(P<0.05,P<0.01)。结论:偏颇体质是骨科大手术患者的中医体质类型特征;气虚质、血瘀质是骨科大手术并发VTE患者的危险因素。     

血小板/淋巴细胞比值联合Grace评分对非ST段抬高型急性冠状动脉综合征院内心血管事件的预测价值

目的评估血小板/淋巴细胞比值(PLR)与非ST段抬高型急性冠状动脉综合征(NSTE-ACS)风险分层及院内预后的相关性及PLR联合Grace评分能否提高Grace评分对院内主要不良心血管事件(MACE)的预测价值。方法选取在青岛大学附属医院心内科住院被诊断为NSTE-ACS的患者372例。根据入院时PLR水平,分为低PLR组(PLR97.56)、中PLR组(97.56≤PLR≤133.32)、高PLR组(PLR133.32)各124例。比较三组之间基线临床资料、Grace评分及院内MACE的差异。依据有无MACE分为有MACE组36例,无MACE组336例,比较两组间基线临床资料、PLR、Grace评分的差异,评估PLR及Grace评分与院内MACE的相关性。应用受试者工作特征(ROC)曲线及DELONG方法评估PLR联合Grace评分与单用Grace评分对院内MACE预测价值的大小。结果(1)高、中、低PLR三组在Grace评分、院内MACE及急性心衰发生方面,差异均有统计学意义(P0.001),且高PLR组中PLR组低PLR组。(2)与无MACE组比较,有MACE组在年龄、尿酸、血小板计数、PLR、Gensini评分、Grace评分水平明显升高,舒张压、肌酐清除率及左心室射血分数指标水平明显降低,差异有统计学意义(P0.01)。(3)多因素Logistic回归分析显示PLR为NSTE-ACS患者发生院内MACE的独立预测因子(P0.01)。(4)ROC曲线分析PLR联合Grace评分预测院内MACE发生的AUC为0.828,单用Grace评分预测院内MACE的AUC为0.793;应用MEDCALC的DELONG方法对两者AUC比较发现差异有统计学意义(P0.05)。结论在NSTE-ACS患者中,PLR为发生院内MACE的独立预测因子,PLR联合Grace评分可显著提高Grace评分对院内MACE的预测价值。
