浅谈不同年龄结节性甲状腺肿合并甲状腺癌患者甲状腺超声特征的临床比较

目的:给予不同年龄结节性甲状腺肿合并甲状腺癌患者实施甲状腺超声检查,对相应的超声检查特征展开分析。方法:选择2018年6月~2019年6月的114例患者为对象,所有患者均被确诊为结节性甲状腺肿合并甲状腺癌,并且利用甲状腺二维超声及多普勒超声对患者进行检查,依据患者年龄阶段均分为两组,每组中各纳入57例患者,年龄超过60岁以上的患者为老年组;年龄在60岁以下的患者为中青年组,对比两组患者的血流相关指标与钙化情况数据。结果:老年组中的平均收缩期流速、阻力指数等数据明显低于中青年组,且比较后P<0.05,具有临床可比较意义。老年组中钙化的总例数为21例,总钙化率占比为36.84%,中青年组中钙化的总例数为38例,总钙化率占比为66.67%,前者数据显著低于后者钙化率,P<0.05。结论:在对结节性甲状腺肿合并甲状腺癌患者实施超声检查后,中青年组患者的病灶呈现低回声、高回声以及伴微小钙化、血流分布以内部血流为主、血流阻力大的特点明显高于老年组,能够显著提升诊断效果,为日后的临床治疗提供了图像依据。     

多元化联合教学模式在超声引导下疼痛介入治疗中的应用

目的探讨多元化联合教学模式在超声引导下疼痛介入治疗教学中的应用效果。方法选择2018年1月至2020年12月在北京大学第三医院疼痛科进修的30名医师作为研究对象,将其分为对照组与观察组;对照组采用常规教学模式;观察组采用多元化联合教学模式,比较两组医师技能考核成绩、教学质量评分和满意度评分。结果观察组医师技能考核成绩优良率为93.3%,高于对照组的73.3%(P<0.05);观察组医师对基础理论知识掌握、临床思维能力的提高、学习兴趣的激发、疾病诊治能力的提高4个方面的评分均高于对照组(P<0.01)。结论多元化联合教学模式可促进超声引导下疼痛介入治疗技能的提高,有利于提高学员的综合临床能力。     

超声引导下辅助诊断和治疗冻结肩的研究进展

冻结肩是常见的肩部疾病,传统非可视化治疗冻结肩效果欠佳。近年来,超声引导具有动态实时定位、无辐射、便携性、低成本等优点在辅助诊断和治疗冻结肩患者中得到成功应用,不仅能提供精确的诊断,也提高了患者中长期的疗效。本文就超声引导辅助诊断和治疗冻结肩的研究进展进行综述。     

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.     

肝移植受者延续护理中应用远程随访管理系统的效果研究

目的:探讨肝移植受者延续护理中应用远程随访管理系统的效果。方法:挑选2018年6月—2019年12月医院接受治疗的60例肝移植受者,在其出院后2周以自制的远程随访管理系统对其展开居家延续护理。结果:医护小组达成了对受者术后疾病状况的远程监控,通过视频交流为病人提供706例次健康指导。所有研究对象对远程随访管理系统的接受率、掌握率、应用时间、每次视频交流时间分别为81.08%、100.00%、(10.53±2.49)d、(12.13±2.69)min。肝移植受者满意度最高的3项依次是视频交流方式、延续护理模式、指导或者咨询内容;延续护理小组满意度最高的3项依次是病情变化处理方法、视频交流方式、指导或者咨询内容。结论:通过远程随访管理,为肝移植受者开展延续护理是现实可行的,不但能使肝移植受者的术后自我管理能力得到有效提升,且受者及延续护理小组都对此系统的应用具有较高的满意度。     

Ultrasound-guided Brachytherapy for Cervix Cancer

Radiotherapy and brachytherapy are the definitive treatments for locally advanced cervix cancer. The use of soft-tissue imaging, particularly magnetic resonance imaging, has enhanced their effectiveness and improved clinical outcomes. However, the use of magnetic resonance imaging is largely restricted to well-resourced centres in both the first and developing world and remains elusive to many less advantaged centres, particularly those in areas with a high burden of cervix cancer. Ultrasound is an accessible, affordable and accurate imaging modality that can be used throughout the brachytherapy procedure. Ultrasound is primarily used to ensure safe insertion of the applicator but can also be used to guide planning. The methods used to utilise ultrasound images for planning are described. Ultrasound is particularly useful as a verification aid to confirm applicator placement after patients are moved and transferred around the radiotherapy department. It can also be used to verify the dimensions of treatment volumes over the course of brachytherapy. There is a crucial unmet need for an accessible economical soft-tissue imaging modality in cervical brachytherapy. Ultrasound has the potential to meet this need.
