Hcy、LPA及TGF-β1在创伤性骨折下肢静脉栓塞中的预测价值

目的分析同型半胱氨酸(Hcy)、溶血磷脂酸(LPA)及转化生长因子-β1(TGF-β1)在创伤性骨折下肢静脉栓塞中的预测价值。方法选取2019年3月至2020年2月商丘市第一人民医院收治的104例创伤性骨折者(观察组),根据有无DVT:有DVT组33例,无DVT组71例;根据创伤严重程度:轻度组61例,重度组43例。另选取本院同期92例健康体检者设为对照组。比较不同人群、不同病情程度以及有无DVT者血浆Hcy、LPA及血清TGF-β1水平,分析Hcy、LPA及TGF-β1对DVT的预测价值。结果观察组Hcy、LPA及TGF-β1表达水平均明显高于对照组,差异均有统计学意义(P<0.05)。重度组Hcy、LPA及TGF-β1表达水平明显高于轻度组,差异均有统计学意义(P<0.05)。有DVT组者Hcy、LPA及TGF-β1表达水平明显高于无DVT组,差异均有统计学意义(P<0.05)。依据ROC曲线分析可知,Hcy+LPA+TGF-β1三者联合预测创伤性骨折后发生DVT敏感度和特异度分别为88.90%、8130%,明显高于三者单独检测(P<0.05)。结论Hcy、LPA及TGF-β1在创伤性骨折发生下肢静脉栓塞时水平均明显升高,三者联合检测对下肢静脉栓塞早期诊断有重要的临床价值。     

Diagnosing pulmonary thromboembolism: Concerns and controversies

Pulmonary thromboembolism (PTE) is an important cause of mortality/morbidity even today despite advancement in clinical understanding as well as diagnostic facilities. Clinical diagnosis of PTE is often challenging because of nonspecific sign/symptoms. Adherence to clinical decision-making protocols and appropriate use of diagnostic modalities like computed tomography pulmonary angiography can resolve the diagnostic dilemma in most cases and help in the overall management of PTE. This article deals with various concerns as well as controversies surrounding accurate diagnosis of PTE as on date.     

Utilization of and Outcomes Associated with Intravascular Ultrasound during Deep Venous Stent Placement among Medicare Beneficiaries

PurposeTo evaluate temporal trends, practice variation, and associated outcomes with the use of intravascular ultrasound (US) during deep venous stent placement among Medicare beneficiaries.Materials and MethodsAll lower extremity deep venous stent placement procedures performed between January 1, 2017, and December 31, 2019 among Medicare beneficiaries were included. Temporal trends in intravascular US use were stratified by procedural setting and physician specialty. The primary outcome was a composite of 12-month all-cause mortality, all-cause hospitalization, or repeat target vessel intervention. The secondary outcome was a composite of 12-month stent thrombosis, embolization, or restenosis.ResultsAmong the 20,984 deep venous interventions performed during the study period, 15,184 (72.4%) utilized intravascular US. Moderate growth in intravascular US use was observed during the study period in all clinical settings. There was a variation in the use of intravascular US among all operators (median, 77.3% of cases; interquartile range, 20.0%–99.2%). In weighted analyses, intravascular US use during deep venous stent placement was associated with a lower risk of both the primary (adjusted hazard ratio, 0.72; 95% confidence interval [CI], 0.69–0.76; P < .001) and secondary (adjusted hazard ratio, 0.32; 95% CI, 0.27–0.39; P < .001) composite end points.ConclusionsIntravascular US is frequently used during deep venous stent placement among Medicare beneficiaries, with further increase in use from 2017 to 2019. The utilization of intravascular US as part of a procedural strategy was associated with a lower cumulative incidence of adverse outcomes after the procedure, including venous stent thrombosis and embolization.     

乳腺癌病人术后发生下肢静脉血栓的影响因素分析及护理对策

目的:探究乳腺癌病人术后发生下肢静脉血栓的影响因素及护理对策。方法:回顾性分析2017年3月—2019年3月在医院进行乳腺癌手术治疗的1388例病人临床资料,根据病人是否在术后发生下肢静脉血栓将其分为血栓组与对照组,比较两组病人一般情况、合并症情况及治疗情况,探究其影响因素,并以此制定护理对策。结果:1388例病人中,共有30例病人并发静脉血栓,其发生率为2.16%;术后发生静脉血栓时间为(5.07±2.11)d;血栓类型以肌间静脉血栓为主,共出现29例,占其全部血栓类型的96.67%;病人血栓发生部位以双下肢为主,占发生血栓病人的46.67%,占全部病人的1.01%。单因素分析结果显示,不同体质指数(BMI)、诊断方法、新辅助化疗、手术时间、年龄的乳腺癌病人术后发生下肢静脉血栓的差异有统计学意义(P<0.05)。Logistic多因素回归分析显示,病人年龄较大、BMI较高、手术活检确诊、接受新辅助化疗、手术时间≥2 h为乳腺癌病人术后发生下肢静脉血栓的独立危险因素。结论:乳腺癌病人术后发生下肢静脉血栓的主要影响因素为年龄较大、BMI较高、手术活检确诊、接受新辅助化疗、手术时间≥2 h。对该类病人,应在提高护理人员护理业务水平及认知水平的基础上,通过对病人进行术前健康教育、改善其生活习惯、评估凝血状态、加强术后观察及避免下肢静脉穿刺等方式避免下肢静脉血栓的发生。     

Acute total hip arthroplasty for older patients with acetabular fractures: A meta-analysis

ObjectiveMultiple treatment options for acetabular fractures in geriatric patients exist. However, no large-scale studies have reported the outcomes of acute total hip arthroplasty (THA) in this patient population. We systematically evaluated all available evidence to characterize clinical outcomes, complications, and revisions of acute THA for acetabular fractures in geriatric patients.MethodsMeta-analysis of 21 studies of 430 acetabular fractures with mean follow-up of 44 months (range, 17−97 months). Two independent researchers searched and evaluated the databases of Ovid, Embase, and United States National Library of Medicine using a Boolean search string up to December 2019. Population demographics and complications, including presence of heterotopic ossification (HO), dislocation, infection, revision rate, neurological deficits, and venous thromboembolic event (VTE), were recorded and analyzed.ResultsWeighted mean Harris Hip Score was 83.3 points, and 20% of the patients had reported complications. The most common complication was HO, with a rate of 19.5%. Brooker grade III and IV HO rates were lower at 6.8%. Hip dislocation occurred at a rate of 6.1%, 4.1% of patients developed VTE, deep infection occurred in 3.8%, and neurological complications occurred in 1.9%. Although the revision rate was described in most studies, we were unable to perform a survival analysis because the time to each revision was described in only a few studies. The revision rate was 4.3%.ConclusionsAcute THA is a viable option for treatment of acetabular fracture and can result in acceptable clinical outcomes and survivorship rates in older patients but with an associated complication rate of approximately 20%. Considering the limited treatment options, THA might be a viable alternative for appropriately selected patients.
