1Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5

3Machine learning models compared to existing criteria for noninvasive prediction of endoscopic retrograde cholangiopancreatography-confirmed choledocholithiasis显示文摘Background and aims:Noninvasive predictors of choledocholithiasis have generally exhibited marginal performance characteristics.We aimed to identify noninvasive independent predictors of endoscopic retrograde cholangiopancreatography(ERCP)-confirmed choledocholithiasis and accordingly developed predictive machine learning models(MLMs).Methods:Clinical data of consecutive patients undergoing first-ever ERCP for suspected chol-edocholithiasis from 2015 to 2019 were abstracted from a prospectively-maintained database.Multiple logistic regression was used to identify predictors of ERCP-confirmed choledocholithiasis.MLMs were then trained to predict ERCP-confirmed choledocholithiasis using pre-ERCP ultrasound(US)imaging only as well as using all available noninvasive imaging(US,computed tomography,and/or magnetic reso-nance cholangiopancreatography).The diagnostic performance of American Society for Gastrointestinal Endoscopy(ASGE)“high-likelihood”criteria was compared to MLMs.Results:We identified 270 patients(mean age 46 years,62.2%female,73.7%Hispanic/Latino,59%with noninvasive imaging positive for choledocholithiasis)with native papilla who underwent ERCP for suspected choledocholithiasis,of whom 230(85.2%)were found to have ERCP-confirmed chol-edocholithiasis.Logistic regression identified choledocholithiasis on noninvasive imaging(odds ratio(OR)¼3.045,P¼0.004)and common bile duct(CBD)diameter on noninvasive imaging(OR¼1.157,P¼0.011)as predictors of ERCP-confirmed choledocholithiasis.Among the various MLMs trained,the random forest-based MLM performed best;sensitivity was 61.4%and 77.3%and specificity was 100%and 75.0%,using US-only and using all available imaging,respectively.ASGE high-likelihood criteria demonstrated sensitivity of 90.9%and specificity of 25.0%;using cut-points achieving this specificity,MLMs achieved sensitivity up to 97.7%.Conclusions:MLMs using age,sex,race/ethnicity,presence of diabetes,fever,body mass index(BMI),total bilirubin,maximum CBD diameter,and choledocholithiasis on pre-ERCP noninvasive imaging predict ERCP-confirmed choledocholithiasis with good sensitivity and specificity and outperform the ASGE criteria for patients with suspected choledocholithiasis.Camellia Dalai John M Azizian Harry Trieu Anand Rajan Formosa C Chen Tien Dong Simon W Beaven James H.Tabibian 2021Liver Research2021,5,4:3
4锌转运体8自身抗体对急性起病糖尿病患者分型诊断的价值显示文摘目的 探讨锌转运体8自身抗体(ZnT8A)对急性起病糖尿病患者分型诊断的价值.方法 453例急性起病糖尿病患者根据谷氨酸脱羧酶抗体(GADA)和酪氨酸磷酸酶抗体(IA2-A)阳性分为A+组276例(任一抗体阳性)和A-组177例(抗体皆为阴性) 将555例2型糖尿病患者和405名健康者作为对照.分析ZnT8A在急性起病糖尿病患者和亚组中的分布规律、相关因素和ZnT8A阳性者的临床特征.抗体检测采用放射配体法.结果 (1)ZnT8A在急性起病糖尿病组的阳性率为24.3%,显著高于2型糖尿病组(1.8%)和健康对照组(1.0%)(均P<0.01) 而且ZnT8A在A+组中的检出率为29.7%,显著高于A-组患者15.8%(x2=11.318,P<0.01).(2)ZnT8A阳性率在<30岁各亚组高于≥30岁亚组(0~9岁,34.9% 10~19岁,26.7% 20~29岁,26.3%比≥30岁,18.3% 均P<0.05) 在体质指数(BMI)<21.0 kg/m2和21.0~25.0 kg/m2亚组高于BMI>25.0 kg/m2亚组(25.5%和25.9%比8.7%,均P<0.05).(3)ZnT8A水平与IA2-A滴度间呈正相关(r=0.165,P=0.01).(4)3种抗体联合测定使自身免疫检出率从60.9%提高到67.1%.(5)与抗体阴性者相比,ZnT8A单独阳性者日胰岛素需要量较多[(35.5±9.3)U/d比(29.8±14.7)U/d,P<0.05],而收缩压和舒张压均较低[(107±15)mm Hg比(113±16)mm Hg,(69±12)mm Hg比(73±12)mm Hg,均P<0.05].结论 ZnT8A对急性起病糖尿病患者的免疫分型诊断有一定价值,在常见抗体(GADA和IA2-A)阴性者中可识别出一类更接近于经典1型糖尿病的临床表型.杨琳 罗说明 黄干 彭健 颜湘 Janet Wenzlau Howard W Davidson John C Hutton 周智广 2010中华医学杂志2010,90,36:2

62009年南极冰穹A的双色天光背景统计和分析显示文摘天光背景是天文台址的一个重要指标。利用2009年位于南极冰穹A的CSTAR望远镜两个波段的观测数据,对南极冰穹A的天光背景进行了统计和分析。结果表明约74%的g波段天光背景的ADU值小于每像素100/s;90.5%的r波段的天光背景的ADU值小于每像素100/s。在不考虑大气消光的情况下,定标后的结果为2009年冰穹A的观测数据中天光背景亮度的中值:g波段为19.9 mag/arcsec2,r波段为20.1 mag/arcsec2。宗伟凯 付建宁 牛家树 Ashley Michael C B 宫雪非 Lawrence J S 刘强 Luong-Van Daniel Pennypacker C R Storey John W V 王灵芝 王力帆 杨惠根 袁祥岩 York Donald G 朱镇熹 2014天文研究与技术2014,11,1:2
