Introduction and objectivesIonizing radiation exposure in catheter ablation procedures carries health risks, especially in pediatric patients. Our aim was to compare the safety and efficacy of catheter ablation guided by a nonfluoroscopic intracardiac navigation system (NFINS) with those of an exclusively fluoroscopy-guided approach in pediatric patients.MethodsWe analyzed catheter ablation results in pediatric patients with high-risk accessory pathways or supraventricular tachycardia referred to our center during a 6-year period. We compared fluoroscopy-guided procedures (group A) with NFINS guided procedures (group B).ResultsWe analyzed 120 catheter ablation procedures in 110 pediatric patients (11 ± 3.2 years, 70% male); there were 62 procedures in group A and 58 in group B. We found no significant differences between the 2 groups in procedure success (95% group A vs 93.5% group B; P = .53), complications (1.7% vs 1.6%; P = .23), or recurrences (7.3% vs 6.9%; P = .61). However, fluoroscopy time (median 1.1 minutes vs 12 minutes; P < .0005) and ablation time (median 96.5 seconds vs 133.5 seconds; P = .03) were lower in group B. The presence of structural heart disease was independently associated with recurrence (P = .03).ConclusionsThe use of NFINS to guide catheter ablation procedures in pediatric patients reduces radiation exposure time. Its widespread use in pediatric ablations could decrease the risk of ionizing radiation.  相似文献

ObjectivesOsteoclasts can sense the surface topography of materials. However, it is difficult to identify the structural factors that affect osteoclast formation and its function. Furthermore, we hypothesized that the type of osteoclast precursor cells also affects osteoclastogenesis in the materials. In this study, we investigated the effects of defined micro/nanoscale patterns on osteoclastogenesis from bone marrow cells (BMCs).MethodsVarious cyclo-olefin polymer (COP) patterns were prepared using nanoimprinting. The effects of shape, size, and height of the patterns, and the wettability of the patterned surfaces on osteoclastogenesis from BMCs were evaluated in vitro.ResultsOsteoclast formation was promoted on pillars (diameter, 1 μm or 500 nm; height, 500 nm). Notably, osteoclastogenesis from BMCs was better promoted on hydrophobic pillars than on hydrophilic pillars. In contrast, decreased osteoclast formation was observed on the nanopillars (diameter, 100 nm; height, 200 nm).ConclusionsWe demonstrated the promotion of osteoclast formation from BMCs on hydrophobic pillars with diameters of 1 μm and 500 nm. Some cellular behaviors in the patterns were dependent on the type of osteoclast precursor cells. The designed patterns are useful for designing the surface of dental implants or bone replacement materials with a controllable balance between osteoblast and osteoclast activities.  相似文献

BackgroundThis study aims to analyze the effect of textbook outcome (TO) on the long-term prognosis and adjuvant chemotherapy (AC) compliance of patients with gastric cancer (GC) in a single institute.Materials and methodsConsecutive patients who underwent radical gastrectomy with pathological stage I-III at Union Hospital of Fujian Medical University from January 2010 to June 2017 were included. TO was defined as receiving a complete-potentially curative status, ≥15 lymph nodes examined, hospital stay ≤21 days, and freedom from intraoperative and postoperative complications, re-intervention in 30 days, 30-day readmission to the hospital or intensive care unit, and 30-day postoperative mortality.ResultsTotally 3993 patients were included, of which 3361 (84.2%) patients achieved TO. The overall, disease-specific, and recurrence-free survival of patients achieving TO were significantly better than those of patients without achieving TO (all P < 0.05). The total number of AC cycles was greater and the interval from surgery to first AC was shorter in the TO group compared with the Non-TO group. Age >65 years old, open surgery, pT3-4 stage, and total radical gastrectomy (TG) were identified as related high-risk factors for failure to achieve TO. Laparoscopic surgery facilitated TO achievement in high-risk groups.ConclusionTO is a reliable indicator of favorable prognosis of patients with GC and contributes to postoperative chemotherapy compliance. Age ≤65 years old, non-TG, pT1-2 stage, and laparoscopic surgery may promote the achievement of TO.  相似文献

目的:观察翼状胬肉切除联合自体带角膜缘上皮的球结膜移植术治疗翼状胬肉患者的疗效观察。

方法:前瞻性对照研究。选取2015-10/2019-10于我院接受治疗的翼状胬肉患者102例102眼,按随机数字表法分为两组:对照组行翼状胬肉切除联合羊膜移植术治疗51眼,观察组行翼状胬肉切除联合自体带角膜缘上皮的球结膜移植术治疗51眼。比较两组患者术中失血量、手术时间、角膜上皮修复时间及术后3mo临床疗效,并记录手术前后泪膜破裂时间(BUT)、裸眼视力(UCVA)、泪液分泌试验(SⅠt)、角膜散光度(CAD)变化情况,以及术后治疗美学量表评分比较和随访过程中的复发情况。

结果:观察组患者角膜上皮修复时间短于对照组(4.14±1.35 vs 4.72±1.37d,P<0.05),手术时间长于对照组(32.24±6.69 vs 29.67±5.21min,P<0.05),而两组术中失血量比较无差异(P>0.05); 术后3mo,两组患者治疗有效率比较无差异(86.3% vs 78.4%,P>0.05),BUT、UCVA、SⅠt较术前均显著上升(均P<0.05),且观察组UCVA、SⅠt显著高于对照组(均P<0.05),两组BUT比较无差异(P>0.05),两组CAD较术前均显著下降(均P<0.05),但组间比较无差异(P>0.05); 术后3mo,观察组翼状胬肉治疗美学量表中眼部恢复、自觉症状评分均显著高于对照组(均P<0.05),而两组间术区清洁及充血情况评分比较无差异(均P>0.05); 两组随访期间的复发率比较无差异(P>0.05)。

结论:翼状胬肉切除联合自体带角膜缘上皮的球结膜移植术可有效治疗翼状胬肉,防止复发,相比于翼状胬肉切除联合羊膜移植术,患者术后恢复更快,美观度更佳。  相似文献

Background/purpose: Rapid detection of β-lactamases is important in a recent situation where resistant bacteria are increasing. By using the drug susceptibility testing microfluidic device (DSTM), rapid screening of extended spectrum β-lactamases (ESBLs) and metallo-β-lactamases (MBLs) has become possible.Methodsβ-lactams and β-lactamase inhibitors were pre-fixed in the DSTM for use. A bacterial suspension in Mueller-Hinton broth (McF 0.25) was introduced into the device, and the effects of β-lactamase inhibitor on morphological changes caused by β-lactam were evaluated after 3 h incubation.ResultsClinical isolates genetically confirmed to produce β-lactamase were used. Of the 84 ESBL-producing strains, 80 strains (95%) turned to be ESBL positive, and five strains (6%) of them MBL were positive as well as ESBL. Four strains (5%) were negative for both ESBL and MBL. Of the 24 MBL-producing strains, 23 strains (96%) were positive for MBL. All the 43 AmpC-producing strains were negative for both ESBL and MBL. Of the 156 ESBL- and MBL-nonproducing strains, 155 strains (99%) were negative for both ESBL and MBL, and one strain was positive for ESBL. With this method, the detection sensitivity was 95% and the specificity was 100% for ESBL, whereas the detection sensitivity was 96% and the specificity was 98% for MBL. These results were not significantly different from the results of the disc diffusion method.ConclusionThe DSTM method allows rapid detection of β-lactamases in 3 h and may be a useful replacement for the disc diffusion method.  相似文献

ObjectivesWe developed a computer-aided diagnosis system called ECRCCAD using standard white-light endoscopy (WLE) for predicting conventional adenomas with high-grade dysplasia (HGD) to optimise the patients' management decisions during colonoscopy.MethodsPretraining model was used to fine-tune the model parameters by transfer learning. 2,397 images of HGD and 2,487 low-grade dysplasia (LGD) images were randomly assigned (8:1:1) to the training, optimising, and internal validation dataset. The prospective validation dataset is the frames accessed from colonoscope videoes. One independent rural hospital provided an external validation dataset. Histopathological diagnosis was used as the standard criterion. The capability of the ECRCCAD to distinguish HGD was assessed and compared with two expert endoscopists.ResultsThe accuracy, sensitivity and specificity for diagnosis of HGD in the internal validation set were 90.5%, 93.2%, 87.9%, respectively. While 88.2%, 85.4%, 89.8%, respectively, for the external validation set. For the prospective validation set, ECRCCAD achieved an AUC of 93.5% in diagnosing HGD. The performance of ECRCCAD in diagnosing HGD was better than that of the expert endoscopist in the external validation set (88.2% vs. 71.5%, P < 0.0001).ConclusionECRCCAD had good diagnostic capability for HGD and enabled a more convenient and accurate diagnosis using WLE.  相似文献
