J Neurosci Methods 2024; 409:110185. [PMID: 38851543 DOI: 10.1016/j.jneumeth.2024.110185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 05/20/2024] [Accepted: 06/02/2024] [Indexed: 06/10/2024]
Abstract
This work was to evaluate the impacts of comprehensive rehabilitation acupuncture therapy on the recovery of neurological function in cerebral infarction (CI) patients and to utilize convolutional neural network (CNN) intelligent algorithms to optimize head computed tomography (CT) images and improve lesion localization accuracy. 98 CI patients were divided into a control group (Ctrl group) and an experimental group (Exp group), with 48 patients in each group. The patients in the Ctrl group received CT evaluation combined with comprehensive rehabilitation acupuncture therapy. While, those in the Exp group received CT evaluation with the use of CNN algorithms for optimization, along with comprehensive rehabilitation acupuncture therapy. Acupuncture therapy included selecting acupoints on the patient's head, selecting two horizontal needling needles from top to bottom at the acupoints on the front side of the lesion, and then horizontal needling along the top midline. The differences in treatment outcomes were compared between the two groups based on Fugl-Meyer upper limb assessment (FMA) scores, Barthel Index (BI) scores, National Institutes of Health Stroke Scale (NIHSS4) scores, Modified Edinburgh-Scandinavian Stroke Scale (MESSS) scores, and hemodynamics. Simultaneously, the CT images were optimized using CNN intelligent algorithms to improve image quality and lesion localization accuracy. The results showed that the CI CT images processed by the CNN-based intelligent algorithm showed significant improvements in clarity and contrast compared to conventional CT images. The CNN-based intelligent algorithm demonstrated higher sensitivity (97.5 %, 93.8 %), higher PSNR (30.14 dB, 24.72 dB), and lower missed detection rate (0.52 %, 1.88 %) in detecting CI lesions. The total effective rate in the Exp group was 95.83 %, which was significantly higher than the 85.42 % in the Ctrl group (P < 0.05). The Exp group showed significantly higher levels in FMA and BI scores (P < 0.05). After treatment, the NIHSS4 and MESSS scores in the Exp group were lower than those in the Ctrl group (P < 0.05). Additionally, post-treatment, the plasma concentrations and whole-blood viscosity (low shear and high shear) in the Exp group were lower than those in the Ctrl group, and the plasma concentration and whole-blood viscosity (high shear) were also lower than those in the Ctrl group (P < 0.05). In conclusion, comprehensive rehabilitation acupuncture therapy had a positive impact on the recovery of neurological function in CI patients. By applying CNN-based intelligent algorithms to optimize head CT images, lesion localization accuracy can be improved, thereby guiding rehabilitation treatment more effectively.

Abstract
Takayasu's arteritis (TAK) is a chronic granulomatous inflammatory disease that involves aorta and its primary branches. It is characterized by wall thickening, stenosis/obliteration or aneurysm formation of the involved arteries. In order to standardize the diagnosis and treatment of TAK in China, a clinical practice guideline with an evidence-based approach is developed under the leadership of National Clinical Medical Research Center for Dermatologic and Immunologic Diseases (NCRC-DID). Eleven recommendations for 11 clinical questions that are important to the diagnosis and treatment of TAK are developed based on the latest evidence and expert opinions combined with real clinical practice in China.

Clin Rheumatol 2023; 42:1625-1634. [PMID: 36787036 DOI: 10.1007/s10067-023-06527-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 12/19/2022] [Accepted: 01/27/2023] [Indexed: 02/15/2023]
Abstract
OBJECTIVE To evaluate the clinical characteristics and nailfold microcirculation and explore the associations with severe ischemic events (SIEs) in Takayasu arteritis (TA) with supra-aortic involvement. METHODS Eighty-one patients with supra-aortic artery involvement who underwent nailfold video-capillaroscopy (NVC) of their hands were enrolled from the East China TA (ECTA) cohort between August and December 2021. Clinical features and capillaroscopy variables associated with supra-aortic SIEs were analyzed by multivariate logistic regression. RESULTS Overall, 71 patients were female, and 42 experienced supra-aortic SIEs, among whom there was a higher prevalence of hypertension and the number of supra-aortic artery stenosis (P = 0.005, and 0.003, respectively). Furthermore, intergroup differences in capillary density (P < 0.001) and minor morphology abnormalities (P < 0.001) were significant. After adjustment for all confounders, multivariate logistic regression revealed hypertension (odds ratio [OR]: 7.3, 95% confidence interval [CI]: 1.6-33.7, P = 0.011), the number of supra-aortic arteries stenosis (≥4, OR: 6.8, 95% CI: 1.4-34.6, P = 0.020), capillary density (≤7.2/mm, OR: 43.0, 95% CI: 7.0-264.6, P < 0.001) and minor abnormalities (OR: 34.2, 95% CI: 3.6-325.1; P = 0.002) were independent risk factors for supra-aortic SIEs. capillary density (≤7.2/mm) and minor abnormalities or combined with at least two of the three items in the matrix model showed the probability of supra-aortic SIEs was 61.2-87.6%. CONCLUSION Decreased capillary density and morphologic abnormalities indicated that hypoperfusion was more likely to be observed in supra-aortic SIEs patients. Combined NVC indicators could be instrumental for early identification of supra-aortic SIEs. Key Points • Minor morphological abnormalities and hemorrhages were only observed in supra-aortic SIEs patients. • Capillaroscopic density and minor morphological abnormalities or combined with at least two of the three items in the matrix model showed the probability occurrence of supra-aortic SIEs was 61.2-87.6%.

Comparison of Presentation and Prognosis of Takayasu Arteritis with or without Stroke or Transient Ischemic Attack-A Retrospective Cohort Study. LIFE (BASEL, SWITZERLAND) 2022; 12:life12111904. [PMID: 36431038 PMCID: PMC9697956 DOI: 10.3390/life12111904] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 11/08/2022] [Accepted: 11/14/2022] [Indexed: 11/18/2022]
Abstract
Takayasu arteritis (TAK) could cause a stroke or transient ischemic attack (TIA) in young individuals due to inflammatory vascular occlusion or intracerebral hemorrhage. We compared the clinical presentation, angiographic features, longitudinal patterns of disease activity, medical treatments, and survival in 34 TAK patients with stroke/TIA and 157 without stroke/TIA from a single-center retrospective cohort. TAK patients with stroke/TIA were older (p = 0.044) with a greater proportion of males (p = 0.022), more frequent vision loss (odds ratio (OR) for stroke/TIA vs. without stroke TIA 5.21, 95% CI 1.42-19.14), and less frequent pulse or blood pressure inequality (OR 0.43, 95% CI 0.19-0.96) than TAK patients without stroke/TIA. Hata's angiographic type IIa was more common in TAK patients with stroke/TIA (OR 11.00, 95%CI 2.60-46.58) and type V in TAK patients without stroke/TIA (OR 0.27, 95% CI 0.12-0.58). Cyclophosphamide was used more often in TAK patients with stroke/TIA (p = 0.018). Disease activity at baseline, 6, 12, and 24 months of follow-up was mostly similar for both groups. Risk of mortality was similar in TAK patients with or without stroke/TIA (hazard ratio unadjusted 0.76, 95% CI 0.15-3.99; adjusted for gender, age of disease onset, delay to diagnosis, baseline disease activity, and the number of conventional or biologic/targeted synthetic immunosuppressants used 1.38, 95% CI 0.19-10.20) even after propensity score-matched analyses. Stroke or TIA does not appear to affect survival in TAK patients adversely.

Abstract
Objective To characterize Takayasu arteritis (TAK) with supra-aortic involvement and determine the associations between clinical features, carotid ultrasonographic (US) parameters, and neurological severe ischemic events (SIE). Methods Patients with supra-aortic involvement including brachiocephalic trunk, bilateral common carotid artery and internal carotid artery, and bilateral subclavian and vertebral artery and baseline carotid US examination were enrolled from the East China Takayasu arteritis cohort. Bilateral carotid diameter, intima-media thickness (IMT), and peak systolic velocity (PSV) were measured by US. Then, IMT/diameter ratio (IDR) was calculated. Risk factors associated with neurological SIE were analyzed by multivariate logistic regression. Results Totally, 295 patients were included, of whom 260 (88.14%) were female, and 93 (31.53%) experienced neurological SIE. Involved supra-aortic artery distribution (p=0.04) and number (p<0.01) differed between neurologic and non-neurologic SIE subjects, showing higher prevalence of common carotid and vertebral artery involvement after Bonferroni correction and 56.99% patients having more than four involved arteries in neurological SIE group. The bilateral IDR (p<0.01) differed between patients with and without neurological SIE. The carotid IDR (left: cut-off value ≥0.55, odds ratio [OR] 2.75, 95% confidence interval [CI] 1.24-6.07, p=0.01; right: ≥0.58, OR 2.70, 95% CI 1.21-6.02, p=0.01) and left carotid PSV (≤76.00 cm/s, OR 3.09; 95% CI 1.53-6.27; p<0.01) as well as involved supra-aortic artery number (≥4, OR 2.33, 95% CI 1.15-4.72, p =0.02) were independently associated with neurological SIE. Conclusion The carotid IDR and PSV might be performed as valuable markers for recognizing neurological SIE in TAK patients with supra-aortic lesions.

Abstract
OBJECTIVES We aimed to investigate the clinical features of Takayasu arteritis (TA) with cerebral infarction (CI) and the risk factors for CI. METHODS The study analysed 122 consecutive patients with TA retrospectively. The clinical characteristics of TA patients with and without CI were compared. Binary logistic regression analysis was performed to determine risk factors for CI in TA patients. RESULTS CI was present in 42 (34.4%) of 122 patients with TA. There were 33 patients with ischemic stroke and 11 with asymptomatic lacunar infarction, including two patients with both types of infarction. The CI group had a significantly higher proportion of males, higher prevalence of blurred vision, and higher Indian Takayasu Clinical Activity Score (ITAS) 2010 than the non-CI group. Binary logistic regression analysis indicated that hyperlipidaemia (OR 5.549, p = 0.021), ITAS 2010 (OR 1.123, p = 0.023), number of involved arteries (OR 1.307, p = 0.018), and middle cerebral artery (MCA) involvement (OR 4.013, p = 0.029) were significantly associated with CI in patients with TA. Receiver operating characteristic curves indicated fair performance of the ITAS 2010 (> 6) and number of involved arteries (> 7) for distinguishing TA patients at risk of CI from those without such risk. CONCLUSION Hyperlipidaemia, higher ITAS 2010, larger number of involved arteries, and MCA involvement are independent risk factors for CI in TA patients.

Intervention in Takayasu Aortitis: When, Where and How? HEARTS 2020. [DOI: 10.3390/hearts1020008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/16/2022] Open
Abstract
Takayasu arteritis is a large vessel vasculitis which commonly affects the aorta and its major branches. Active arterial inflammation is characterised by the presence of T and B lymphocytes, natural killer cells, macrophages and occasional multinucleate giant cells. Uncontrolled vascular inflammation can progress to cause arterial stenosis, occlusion or aneurysmal dilatation. Medical treatment involves combination immunosuppression and more recently biologic therapies targeting TNF-α and IL-6. Due to the typical delays in diagnosis and accumulation of arterial injury, open and endovascular surgical intervention are important and potentially life-saving treatment options for Takayasu arteritis. Common indications for surgery include aortic coarctation and ascending aortic dilatation ± aortic valve regurgitation, renal artery stenosis, ischaemic heart disease, supra-aortic disease, mesenteric ischaemia, severe limb-threatening claudication and aneurysm repair. Surgical outcomes are markedly improved in patients with clinically inactive disease and those who receive adequate periprocedural immunosuppression. Decisions regarding surgical approaches are best made as part of a multi-disciplinary team.
