《JACC: Cardiovascular Interventions》2022,15(8):846-856
ObjectivesThe aim of this study was to test whether optical coherence tomographic (OCT) guidance would provide additional useful information beyond that obtained by angiography and lead to a shift in reperfusion strategy and improved clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) with early infarct artery patency.BackgroundAngiography is limited in assessing the underlying pathophysiological mechanisms of the culprit lesion.MethodsEROSION III (Optical Coherence Tomography–Guided Reperfusion in ST-Segment Elevation Myocardial Infarction With Early Infarct Artery Patency) is an open-label, prospective, multicenter, randomized, controlled study approved by the ethics committees of participating centers. Patients with STEMI who had angiographic diameter stenosis ≤ 70% and TIMI (Thrombolysis In Myocardial Infarction) flow grade 3 at presentation or after antegrade blood flow restoration were recruited and randomized to either OCT guidance or angiographic guidance. The primary efficacy endpoint was the rate of stent implantation.ResultsAmong 246 randomized patients, 226 (91.9%) constituted the per protocol set (112 with OCT guidance and 114 with angiographic guidance). The median diameter stenosis was 54.0% (IQR: 48.0%-61.0%) in the OCT guidance group and 53.5% (IQR: 43.8%-64.0%) in the angiographic guidance group (P = 0.57) before randomization. Stent implantation was performed in 49 of 112 patients (43.8%) in the OCT group and 67 of 114 patients (58.8%) in the angiographic group (P = 0.024), demonstrating a 15% reduction in stent implantation with OCT guidance. In patients treated with stent implantation, OCT guidance was associated with a favorable result with lower residual angiographic diameter stenosis (8.7% ± 3.7% vs 11.8% ± 4.6% in the angiographic guidance group; P < 0.001). Two patients (1 cardiac death, 1 stable angina) met the primary safety endpoint in the OCT guidance group, as did 3 patients (3 cardiac deaths) in the angiographic guidance group (1.8% vs 2.6%; P = 0.67). Reinfarction was not observed in either group. At 1 year, the rates of predefined cardiocerebrovascular events were comparable between the groups (11.6% after OCT guidance vs 9.6% after angiographic guidance; P = 0.66).ConclusionsIn patients with STEMI with early infarct artery patency, OCT guidance compared with angiographic guidance of reperfusion was associated with less stent implantation during primary percutaneous coronary intervention. These favorable results indicate the value of OCT imaging in optimizing the reperfusion strategy of patients with STEMI.

Clinical feature and predictive factor analysis for spontaneous regression of retinopathy of prematurity in a Chinese population 下载免费PDF全文
AIM: To investigate the ratio of spontaneous regression of retinopathy of prematurity (ROP) and to explore the possible relevant predictive factors.
METHODS: A retrospective review of 405 infants who were diagnosed with ROP and mother during pregnancy were collected. Stage, zone, and duration of ROP were recorded. Statistical analysis was performed on 51 possible predictive factors.
RESULTS: Totally 356 infants showed spontaneous regression. The incidence was 100%, 95.3%, and 22.7% in stage 1, 2, and 3, respectively. The 13.4% of the ROP with plus disease eventually resolved spontaneously. All affected eyes of aggressive posterior retinopathy of prematurity (AP-ROP) failed to spontaneously regress. The mean duration of ROP was 7.2wk in patients with spontaneous resolution of ROP. Days of mechanical ventilation (OR=0.981, 95%CI, 0.965-0.997, P=0.021), retinal hemorrhage (OR=0.173, 95%CI, 0.064-0.470, P=0.001), delivery pattern (OR=2.750, 95%CI, 1.132-6.681, P=0.025), maternal anemia in pregnancy (OR=0.142, 95%CI, 0.036-0.563, P=0.005), the stages (at initial diagnosis OR=0.183, 95%CI, 0.041-0.816, P=0.026; at final diagnosis OR=0.031, 95%CI, 0.006-0.167, P<0.001), and with plus disease or not (OR=0.005, 95%CI, 0.001-0.031, P<0.001) were independent predictive factors of the spontaneous regression of ROP.
CONCLUSION: Most mild ROP can spontaneously resolve. Active treatment is still recommended for stage 3 ROP, zone I ROP, AP-ROP, and ROP with plus disease. Prolonged mechanical ventilation and concurrent retinal hemorrhage reduce the likelihood of spontaneous ROP resolution. The pattern of delivery and the mother’s anemia during pregnancy can also affect the prognosis of ROP. 相似文献

《Seminars in Fetal & Neonatal Medicine》2022,27(6):101406
Recently, two randomized controlled, prospective trials, the Tracheal Occlusion to Accelerate Lung Growth (TOTAL) trials, reported the outcomes on fetal endoluminal tracheal occlusion (FETO) for isolated left congenital diaphragmatic hernia (CDH). FETO significantly improved outcomes for severe hypoplasia. The effect in moderate cases, where the balloon was inserted later in pregnancy, did not reach significance. In a pooled analysis investigating the effect of the heterogeneity of the treatment effect by the time point of occlusion and severity, the difference may be explained by a difference in the duration of occlusion. Nevertheless, FETO carries a significant risk of preterm birth. The primary objective of this review is to provide an overview of the rationale for fetal intervention in CDH and the results of the randomized trials. The secondary objective is to discuss the technical aspects of FETO. Finally, recent developments of potential alternative fetal approaches will be highlighted. 相似文献

Empirical antibiotic therapy in patients with spontaneous bacterial peritonitis (SBP) is common as pathogen(s) are identified in only 5%-20% patients using conventional culture-based techniques. Metagenome next-generation sequencing (mNGS) test is a promising approach for the diagnosis of infectious disease. The clinical application of mNGS for infected ascites in cirrhotic patients is rarely reported. Here, we describe three cases to preliminarily explore the potential role of mNGS for microbiological diagnosis of ascites infection in an exploratory manner. The clinical performance of ascites mNGS in cirrhotic patients remains to be further evaluated. 相似文献

呼吸机自动测量气道阻断压与标准测量方法的一致性 《首都医科大学学报》2022,43(5):728-733
目的 验证呼吸机自动测量的气道阻断压(airway occlusion pressure,P0.1)与标准测量方法的一致性,以及不同触发形式对自动测量结果的影响。方法 选择采用非阻断自动测量P0.1的呼吸机,分别进行模拟肺和临床试验。调节全自动自主呼吸模拟肺,模拟具有不同呼吸努力和呼吸力学特征的48种状态,应用待检测呼吸机,以压力支持通气模式为模拟肺进行通气。临床研究部分纳入15例接受压力支持通气的成年患者。两部分研究均随机交叉应用压力和流量触发,采集呼吸机自动监测的P0.1后,采用标准呼气末气道阻断法进行P0.1测量,作为标准参考值。采用Bland-Altman检验分析P0.1呼吸机监测值与标准参考值的一致性,计算残差(呼吸机监测值-标准参考值)和95%一致性区间,比较不同触发形式对残差的影响。结果 在模拟肺验证中,P0.1呼吸机监测值与标准参考值之间的残差(95%一致性区间)在压力和流量触发下分别为0.04(-0.63~0.70)和-0.54(-1.44~0.36)cmH2O(1 cmH2O=0.098 kPa),两者相比差异具有统计学意义(P<0.001)。临床观察获得了相似的结果,压力和流量触发时的残差(95%一致性区间)分别为-0.11(-0.73~0.52)和-0.54(-1.50~0.59)cmH2O,差异无统计学意义(P>0.05),表明呼吸机监测值与标准参考值间存在一致性。结论 压力触发时,呼吸机非阻断法自动测量的P0.1与标准方法具有良好的一致性。而流量触发明显低估P0.1,建议自动监测时切换到压力触发。 相似文献

目的:探讨急性闭合性断裂跟腱组织形态学与超微结构变化。方法:回顾分析2015年1月至2019年1月采用跟腱微创缝合技术治疗的急性跟腱断裂患者35例,其中急性开放性跟腱断裂12例,男10例,女2例,年龄19~50(35.1±9.7)岁,受伤至手术时间2~8(5.6±1.8)h。急性闭合性跟腱断裂23例,男21例,女2例,年龄18~50(35.5±6.6)岁,受伤至手术时间3~15(7.5±3.1)h。于术前4~6 h通过肉眼观察及足踝部MRI比较两组患者跟腱组织断端的大体外观和影像学表现;于术后1~2 d对术中跟腱组织标本进行HE染色、扫描及透视电镜、免疫组化(天狼星红染色),分别比较两组跟腱组织的胶原纤维变性及局部脂肪浸润情况,胶原纤维走行及细胞形态、功能情况,Ⅰ型胶原纤维(collagenⅠ)和Ⅲ型胶原纤维(collagenⅢ)在组织中的分布情况。结果:与急性开放性跟腱断裂组相比,急性闭合性跟腱断裂组跟腱组织弹性差、质地偏硬,中度水肿,跟腱断端形态不规则,呈马尾状且断端周围有较多钙化灶。HE染色结果:急性闭合性跟腱断裂组跟腱组织中胶原纤维排列不规则,有玻璃样变及脂肪侵润。电镜检查结果:急性闭合性跟腱断裂组胶原排列紊乱,成纤维细胞萎缩。免疫组化(天狼星染色)结果:急性开放性跟腱断裂组和急性闭合性跟腱断裂组Ⅰ型胶原占比分别为(91.12±4.34)%及(54.71±17.78)%,Ⅲ型胶原占比分别为(8.88±4.34)%及(45.29±17.78)%,急性闭合性跟腱断裂组Ⅰ型胶原含量低于急性闭开放跟腱断裂组,Ⅲ型胶原含量高于急性闭合性跟腱断裂组(P<0.05)。结论:急性闭合性断裂跟腱形态组织学及超微结构发生明显改变,原本精细有序的空间结构无法维持,部分Ⅰ型胶原被Ⅲ型胶原替代,肌腱组织的韧性和强度下降,这是跟腱退行性变的重要特征,是闭合性跟腱断裂重要病理基础。 相似文献

背景 复发性流产(RSA)发病率呈逐年上升趋势,严重影响妇女身心健康,目前现代医学对RSA的病因和发病机制尚未完全明确。目的 了解RSA病因的分布情况,以及流产孕周与流产次数和RSA病因之间的关系。方法 选取2018年在新疆医科大学第二附属医院确诊为RSA的患者198例,收集患者的一般资料包括年龄、自然流产次数、流产孕周,并筛查患者的病因:染色体异常、生殖道解剖结构异常、内分泌系统异常、生殖道感染、自身免疫异常等,并对这些资料进行回顾性分析。根据患者的流产孕周,分为早期RSA组(<12周)(155例)和晚期RSA组(≥12周)(43例);根据流产次数分为2次组(123例)和≥3次组(75例)。分析RSA患者各病因所占比例,以及RSA病因在不同流产孕周组和不同流产次数组间的差异。结果 198例RSA患者,染色体异常9例(4.55%),生殖道解剖结构异常11例(5.56%),内分泌系统异常36例(18.18%),生殖道感染14例(7.07%),自身免疫异常30例(15.15%),不明病因98例(49.49%)。晚期RSA组患者生殖道解剖结构异常发生率大于早期RSA组,不明病因发生率低于早期RSA组(P<0.05);早期RSA组与晚期RSA组患者染色体异常、内分泌系统异常、生殖道感染、自身免疫异常发生率比较,差异均无统计学意义(P>0.05)。流产次数2次组和流产次数≥3次组患者染色体异常、生殖道解剖结构异常、内分泌系统异常、生殖道感染、自身免疫异常、不明病因发生率比较,差异均无统计学意义(P>0.05)。结论 导致RSA的病因有多种,包括染色体异常、生殖道解剖结构异常、内分泌系统异常、生殖道感染、自身免疫异常及不明病因等多种因素,其中不明病因的RSA占多数;生殖道解剖结构异常对妊娠晚期的影响大于妊娠早期。 相似文献
