Computed tomography coronary angiography after excluding myocardial infarction:high-sensitivity troponin versus risk score-guided approach

World Journal of Emergency Medicine 2023年第6期14卷 428-433页

BACKGROUND:Patients with suspected acute coronary syndrome (ACS) in whom myocardial infarction has been ruled out are still at risk of having obstructive coronary artery disease (CAD).This rate is higher among patients with intermediate high-sensitivity troponin I (hsTnI) concentrations (5 ng/L to 99th percentile) than low concentrations (<5 ng/L).Therefore,an intermediate concentration has been suggested as a candidate for downstream investigation with computed tomography coronary angiography(CTCA).We tried to compare the HEART score-guided ***-guided approach for identifying obstructive ***:From a prospective cohort study of patients presenting to the emergency department with suspected ACS,433 patients without elevated hsTnI who also underwent CTCA were selected and *** performances of hsTnI concentration and HEART score were compared using sensitivity,specificity,positive predictive value (PPV),and negative predictive value (NPV).RESULTS:Overall,120 (27.7%) patients had obstructive *** with intermediate hsTnI concentrations were more likely to have obstructive CAD than those with low hsTnI concentrations(40.0%vs.18.1%);patients with non-low-risk HEART scores (≥4 points) were also more likely to have obstructive CAD than those with low-risk scores (0 to 3 points)(41.0%vs.7.6%).The HEART score had higher sensitivity and NPV for detecting obstructive CAD in each classification than hsTnI concentration (sensitivity:89.2%vs.63.3%;NPV:92.4%vs.81.9%,respectively).CONCLUSION:After excluding myocardial infarction in patients with suspected ACS,adding the HEART score for selecting candidates for CTCA could improve patient risk stratification more accurately than relying on hsTnI concentration.

Two-dimensional(2D)MXenes are promising as electrode materials for energy storage,owing to their high electronic conductivity and low diffusion ***,similar to most 2D materials,MXene nanosheets easily restack during the electrode preparation,which degrades the electrochemical performance of MXene-based materials.A novel synthetic strategy is proposed for converting MXene into restacking-inhibited three-dimensional(3D)balls coated with iron selenides and *** strategy involves the preparation of Fe_(2)O_(3)@carbon/MXene microspheres via a facile ultrasonic spray pyrolysis and subsequent selenization *** 3D structuring effectively prevents interlayer restacking,increases the surface area,and accelerates ion transport,while maintaining the attractive properties of ***,combining iron selenides and carbon with 3D MXene balls offers many more sites for ion storage and enhances the structural robustness of the composite *** resultant 3D structured microspheres exhibit a high reversible capacity of 410 mAh g^(−1) after 200 cycles at 0.1 A g^(−1) in potassium-ion batteries,corresponding to the capacity retention of 97% as calculated based on 100 *** at a high current density of 5.0 A g^(−1),the composite exhibits a discharge capacity of 169 mAh g^(−1).

作者： Jang Ho Cho jae yun Lim jae Yong Cho Division of Medical Oncology Department of Internal Medicine Gangnam Severance Hospital Yonsei University College of Medicine

AIM To investigate human epidermal growth factor 2(HER2) overexpression and validate its prognostic effect in stage Ⅱ-Ⅲ gastric *** We reviewed the data of patients who were diagnosed with gastric cancer between March 2008 and October 2013 at the Yonsei University Medical Center. Among these patients, 384 patients who met the inclusion criteria were analyzed retrospectively. RESULTS Thirty-two(8.3%) of the 384 stage Ⅱ-Ⅲ gastric cancer patients exhibited HER2 overexpression. The median follow-up duration was 26.0 mo. HER2-negative patients had superior recurrence-free survival(RFS) compared to HER2-positive patients(HR = 0.52, 95%CI: 0.30-0.89; P = 0.015). The median overall survival(OS) was significantly prolonged in the HER2-negative group compared with the HER2-positive group(55.0 mo vs 38.0 mo, HR = 0.43, 95%CI: 0.21-0.88, P = 0.021). OS was also prolonged in HER2-negative patients who received adjuvant chemotherapy compared to HER2-positive patients(55.0 vs 38.0mo, HR = 0.42, 95%CI: 0.18-1.00, P = 0.051). In patients who did not receive adjuvant chemotherapy,the median RFS was prolonged in the HER2-negative group compared to the HER2-positive group(not reached vs 12.0 mo, HR = 0.17, 95%CI: 0.06-0.49, P= 0.001). In a multivariate analysis, HER2 status(HR= 0.421, 95%CI: 0.206-0.861, P = 0.018) and Eastern Cooperative Oncology Group performance status(HR = 2.002, 95%CI: 1.530-2.618, P < 0.001) were independent predictors of *** Our findings showed that HER2-positive patients had inferior OS and RFS. Stage Ⅱ-Ⅲ HER2-positive patients might be potential candidates for targeted therapies involving trastuzumab.
