However, for ticagrelor, the impact of serial PRU testing and the identification of safe PRU ranges remains unexplored.MethodsFlow diversion stenting (n = 232) and stent-assisted coiling procedures (n = 83) performed 05/2017-12/2021 were reviewed. Out of these, 31 flow diversion and 18 stent-coiling procedures were performed on 44 patients using ticagrelor. Baseline demographics, ticagrelor PRUs, and clinical outcomes were assessed.ResultsCollectively, 257 ticagrelor P2Y12 PRUs were obtained. PRUs were <100 in 192/257 (74.7%) tests. Only 11/257 (4.3%) PRUs were >200. The overall median ticagrelor PRU was 38 (IQR 11-101). Among the 49 procedures, median PRUs before the procedure (25, IQR 10-67), on the day of the procedure (68, IQR 44-117), and on the day after the procedure (37, IQR 21-79) did not show the significant differences between the groups. A total of seven thromboembolic complications occurred. Median PRUs surrounding the thromboembolic complications (median 182, IQR 148-235) were significantly higher than preprocedural (p < .001), day of surgery (p < .01), and postprocedural PRUs (p < .01). All seven procedures harbored demographic, anatomic, or procedural features increasing the risk for thromboembolic complications.DiscussionThe majority of periprocedural ticagrelor PRUs were <100. PRUs at the time point of thromboembolic complications were >120. Despite procedure-complicating features in each thromboembolic case, it raises the question whether safe ticagrelor PRU levels might be lower than those commonly applied for clopidogrel.","PeriodicalId":47358,"journal":{"name":"Neuroradiology Journal","volume":" ","pages":"331-336"},"PeriodicalIF":0.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11607722/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142755645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through femoral access, an 8-French sheath was introduced into the right femoral artery through which a Zoom 88 catheter was introduced and parked at the right petrous ICA segment in case 1 and left ophthalmic ICA segment in case 2. Angiogram demonstrated complete ICA occlusion just past the ophthalmic artery origin in case 1 and at the ICA terminus in case 2. Zoom system (88 and 71) was then navigated to the face of clot with vacuum manifold engaged with the clot. TICI 2B (with the help of Trevo stent retriever [Stryker]) and TICI 3 recanalization were achieved in cases 1 and 2, respectively.ConclusionThe use of Zoom reperfusion system could potentially be feasible for use in pediatric age group.

Use of right superficial temporal artery to middle cerebral artery bypass and aorta-right subclavian bypass resulted in improved flow to the right hemisphere on quantitative magnetic resonance angiography and single-photon emission computed tomography, significantly lowering the risk of catastrophic ischemic stroke.

The presence of the telomerase reverse transcriptase promoter (pTERT) mutation is associated with a better prognosis.

The electronic databases of PubMed, Embase, Scopus, and Web of Science were searched from inception to August 1, 2023. The statistical analysis was performed using the MIDAS package of STATA v.17.ResultsA total of 22 studies involving 5371 patients were included for data extraction, with data synthesis based on 11 reports. The analysis revealed a pooled sensitivity of 0.86 (95% CI: 0.78-0.92) and a specificity of 0.80 (95% CI 0.72-0.86). The positive and negative likelihood ratios were 4.23 (95% CI: 2.99-5.99) and 0.18 (95% CI: 0.11-0.29), respectively.

The Summary Receiver Operating Characteristic (SROC) curve had an area under the curve (AUC) of 0.89 (95% CI: 0.86-0.91).ConclusionThe study suggests that ML can predict TERT mutation status in glioma patients.

This study investigates the impact of lifestyle changes following retirement on the incidence of these procedures, hypothesizing that retirement significantly influences the requirement for such treatments.MethodsA review of medical records from XXX County between 2000 and 2023 was conducted, focusing on patients who received spinal injections, including epidural steroid, facet, and sacroiliac joint injections. Data were stratified by age, employment status pre- and post-procedure, and type of injection. Statistical analysis, including segmental linear regression and t-tests, was used to assess changes in incidence rates over time and across demographic subsets.ResultsOut of 134,318 patients analyzed, a total of 359,224 spinal injections were performed. There was a significant (p-value <.01) increase in the frequency of procedures among individuals around the age of 60, which coincides with the typical retirement age in the United States. The study also highlighted a subsequent decline in the incidence of these procedures between the ages of 70 and 74, suggesting potential adaptation to chronic conditions or the effectiveness of earlier treatments.ConclusionThe findings of this study confirm the hypothesis that retirement significantly impacts the demand for spinal injections, as evidenced by the marked increase in procedures at typical retirement ages. This underscores the importance of integrating preventive care and personalized medical guidance into healthcare strategies for individuals nearing retirement to effectively manage spine-related pain disorders and reduce the necessity for invasive treatments.","PeriodicalId":47358,"journal":{"name":"Neuroradiology Journal","volume":" ","pages":"19714009251345115"},"PeriodicalIF":1.3,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12125015/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144180270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various imaging features were examined, including tumor size, shape (lobulated or round), base width (narrow or broad), presence of cystic necrosis, calcification, signal intensity on T1- and T2-weighted MRI, intravascular flowing-void signs, peritumoral edema, CT attenuation values on non-enhanced and enhanced scans, and adjacent bone destruction. Chi-square tests, t-tests, ROC curves, and multivariate logistic regression were used to establish predictive models.
