5National trends in total hip arthroplasty for traumatic hip fractures:An analysis of a nationwide all-payer database显示文摘BACKGROUND Hemiarthroplasty(HA)has traditionally been the treatment of choice for elderly patients with displaced femoral neck fractures.Ideal treatment for younger,ambulatory patients is not as clear.Total hip arthroplasty(THA)has been increasingly utilized in this population however the factors associated with undergoing HA or THA have not been fully elucidated.AIM To examine what patient characteristics are associated with undergoing THA or HA.To determine if outcomes differ between the groups.METHODS We queried the Nationwide Inpatient Sample(NIS)for patients that underwent HA or THA for a femoral neck fracture between 2005 and 2014.The NIS comprises a large representative sample of inpatient hospitalizations in the United States.International Classifications of Disease,Ninth Edition(ICD-9)codes were used to identify patients in our sample.Demographic variables,hospital characteristics,payer status,medical comorbidities and mortality rates were compared between the two procedures.Multivariate logistic regression analysis was then performed to identify independent risk factors of treatment utilized.RESULTS Of the total 502060 patients who were treated for femoral neck fracture,51568(10.3%)underwent THA and the incidence of THA rose from 8.3%to 13.7%.Private insurance accounted for a higher percentage of THA than hemiarthroplasty.THA increased most in urban teaching hospitals relative to urban non-teaching hospitals.Mean length of stay(LOS)was longer for HA.The mean charges were less for HA,however charges decreased steadily for both groups.HA had a higher mortality rate,however,after adjusting for age and comorbidities HA was not an independent risk factor for mortality.Interestingly,private insurance was an independent predictor for treatment with THA.CONLUSION There has been an increase in the use of THA for the treatment of femoral neck fractures in the United States,most notably in urban hospitals.HA and THA are decreasing in total charges and LOS.Anthony J Boniello Alexander M Lieber Kevin Denehy Priscilla Cavanaugh Yehuda E Kerbel Andrew Star 2020World Journal of Orthopedics2020,11,1:1

9TiO_2纳米纺锤体负载Pt在氧还原反应中的应用(英文)显示文摘燃料电池中催化剂的稳定性是影响其实际应用的关键问题之一。本研究合成了锐钛矿型纺锤状TiO_2纳米材料,并负载纳米Pt制备了TiO_2-Pt双组分复合催化材料。将其制作成电极材料后,进行了TEM、XRD、拉曼光谱、电化学特性分析。结果表明:TiO_2-Pt材料中Pt纳米颗粒的TEM形貌与TiO_2的表面亲和力有关;该双组分催化剂呈现出两个单独的氧还原反应(ORR)峰;在负载Pt后,材料电荷传输电阻明显减小,使得TiO_2-Pt中TiO_2纺锤体组分上的ORR性能明显增强;紫外光可同时促进TiO_2-Pt中两组分的ORR性能;TiO_2-Pt比炭黑负载Pt具有更好的稳定性。彭桂明 巫素琴 彭全明 BURKERT Seth C. 杜瑞安 余长林 STAR Alexander 2018新能源进展2018,6,2:0
