Notably, in IVT-LVO cohort, 58.2% of the PIM-DT positive patients achieved an excellent outcome compared with 31.0% in non-mismatch patients following successful recanalization (P = 0.006).]]> Wed 28 Sep 2022 14:35:18 AEST ]]> Optimal CT perfusion thresholds for core and penumbra in acute posterior circulation infarction https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53333 1 s and MTT>145%. Delay time (DT) best estimated the infarct core (AUC = 0.74). The optimal core threshold was a DT >1.5 s. The voxel-based analyses indicated CTP was most accurate in the calcarine (Penumbra-AUC = 0.75, Core-AUC = 0.79) and cerebellar regions (Penumbra-AUC = 0.65, Core-AUC = 0.79). For the volume-based analyses, MTT >160% demonstrated best correlation and smallest mean-volume difference between the penumbral estimate and follow-up MRI (R2 = 0.71). MTT >170% resulted in the smallest mean-volume difference between the core estimate and follow-up MRI, but with poor correlation (R2 = 0.11). Conclusion: CTP has promising diagnostic utility in POCI. Accuracy of CTP varies by brain region. Optimal thresholds to define penumbra were DT >1 s and MTT >145%. The optimal threshold for core was a DT >1.5 s. However, CTP core volume estimates should be interpreted with caution.]]> Wed 28 Feb 2024 16:20:57 AEDT ]]> Opposing associations of stress and resilience with functional outcomes in stroke survivors in the chronic phase of stroke: a cross-sectional study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45158 N = 70) who had experienced a stroke between 5 months and 28 years ago were included in the cross-sectional study, along with age-matched controls (N = 70). We measured stress using both the Perceived Stress Scale and biological markers, and resilience using both the Brief Resilience Scale and the Connor-Davidson Resilience Scale. Stroke outcomes were assessed using the Stroke Impact Scale. We found that, compared with age-matched controls, stroke survivors reported greater levels of perceived stress, and lower levels of resilience. In stroke survivors, both perceived stress and resilience were independently associated with stroke outcomes in linear regression models. In particular, these relationships were observed for cognitive outcomes including mood, memory, and communication. The association between stress and stroke outcome did not differ across time post stroke. Given that resilience is a modifiable psychological construct, future research may consider whether strategies directed at enhancing resilience may improve recovery from stroke.

Methods: A discrete event simulation (DES) model was developed to simulate the long-term outcome post EVT in patients meeting or not meeting the extended time window clinical trial perfusion imaging criteria at presentation, vs. medical treatment alone (including intravenous thrombolysis). The effectiveness of thrombectomy in patients meeting the landmark trial criteria (DEFUSE 3 and DAWN) was derived from a prospective cohort study of Australian patients who received EVT for ischemic stroke, between 2015 and 2019, in the extended time window (>4.5 h). Results: Endovascular thrombectomy was shown to be a cost-effective treatment for patients satisfying the clinical trial criteria in our prospective cohort [incremental cost-effectiveness ratio (ICER) of $11,608/quality-adjusted life year (QALY) for DEFUSE 3-postive or $34,416/QALY for DAWN-positive]. However, offering EVT to patients outside of clinical trial criteria was associated with reduced benefit (−1.02 QALY for DEFUSE 3; −1.43 QALY for DAWN) and higher long-term patient costs ($8,955 for DEFUSE 3; $9,271 for DAWN), thereby making it unlikely to be cost-effective in Australia. Conclusions: Treating patients not meeting the DAWN or DEFUSE 3 clinical trial criteria in the extended time window for EVT was associated with less gain in QALYs and higher cost. Caution should be exercised when considering this procedure for patients not satisfying the trial perfusion imaging criteria for EVT.]]> Thu 24 Mar 2022 08:55:17 AEDT ]]> Systematic Review of Pre-injury Migraines as a Vulnerability Factor for Worse Outcome Following Sport-Related Concussion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51858 Thu 21 Sep 2023 09:41:25 AEST ]]> Excitability of rat superficial dorsal horn neurons following a neonatal immune challenge https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44697 Thu 20 Oct 2022 09:51:36 AEDT ]]> Machine learning segmentation of core and penumbra from acute stroke CT perfusion data https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52638 Thu 19 Oct 2023 15:12:05 AEDT ]]> A multinational cost-consequence analysis of a bone conduction hearing implant system - a randomized trial of a conventional vs. a less invasive treatment with new abutment technology https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38255 Thu 19 Aug 2021 12:14:52 AEST ]]> Air vs. road decision for endovascular clot retrieval in a rural telestroke network https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38503 Thu 18 Nov 2021 09:53:11 AEDT ]]> Optimal Delay Time of CT Perfusion for Predicting Cerebral Parenchymal Hematoma After Intra-Arterial tPA Treatment https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43334 2, >4, >6, >8, and >10 s) with PH was examined using receiver operating characteristic (ROC) analysis and logistic regression. Results: Of 94 patients, 23 developed PH on follow-up imaging. Receiver operating characteristic analysis revealed that the greatest area under the curve for predicting PH occurred at DT > 4 s (area under the curve, 0.66). At this threshold of > 4 s, DT lesion volume ≥ 30.85 mL optimally predicted PH with 70% sensitivity and 59% specificity. DT > 4 s volume was independently predictive of PH in a multivariate logistic regression model (P < 0.05). Conclusions: DT > 4 s was the parameter most strongly associated with PH. The volume of moderate, not severe, hypo-perfusion on DT is more strongly associated and may allow better prediction of PH after intra-arterial tPA thrombolysis.]]> Thu 15 Sep 2022 15:04:25 AEST ]]> Onset symptoms, Tobacco smoking, and progressive-onset phenotype are associated with a delayed onset of multiple sclerosis, and marijuana use with an earlier onset https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43333 Thu 15 Sep 2022 14:57:26 AEST ]]> Growth hormone deficiency is frequent after recent stroke https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33725 Thu 13 Jan 2022 10:30:08 AEDT ]]> Development and Pilot Implementation of TACTICS VR: A Virtual Reality-Based Stroke Management Workflow Training Application and Training Framework https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40631 Thu 11 Aug 2022 09:02:28 AEST ]]> Endovascular thrombectomy for ischemic stroke increases disability-free survival, quality of life, and life expectancy and reduces cost https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31270 Thu 09 Dec 2021 11:04:26 AEDT ]]> Dynamic CT but not optimized multiphase CT angiography accurately Iidentifies CT perfusion target mismatch ischemic stroke patients https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46655 Mon 28 Nov 2022 17:43:31 AEDT ]]> A systematic review of the usefulness of glial fibrillary acidic protein for predicting acute intracranial lesions following head trauma https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31141 Mon 26 Nov 2018 11:08:21 AEDT ]]> Risk for Misdiagnosing Chronic Traumatic Encephalopathy in Men With Anger Control Problems https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42344 Mon 22 Aug 2022 13:54:55 AEST ]]> Delayed filling of the superficial middle cerebral vein in acute large artery occlusion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52319 Mon 22 Apr 2024 14:04:17 AEST ]]> Filling Defect of Ipsilateral Transverse Sinus in Acute Large Artery Occlusion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51794 0.05).

Increased stroke risk also predicted performance on the cognitive screening test and the measure of executive functioning (all p < 0.002). Conclusions: Our findings indicate that cognitive impairment following a minor stroke or TIA may be attributed to the high prevalence of chronic vascular risk factors in these patients. This highlights the importance of long-term management of vascular risk factors beyond event recovery to reduce the risk of cognitive impairment. Increased stroke risk (i.e., ABCD2 score) was also associated with reduced cognition, suggesting that it may be helpful in signaling the need for further cognitive evaluation and intervention post-event.]]> Fri 20 May 2022 12:40:50 AEST ]]> Relapse Patterns in NMOSD: Evidence for Earlier Occurrence of Optic Neuritis and Possible Seasonal Variation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42294 Fri 19 Aug 2022 14:58:38 AEST ]]> Reduced Impact of Endovascular Thrombectomy on Disability in Real-World Practice, Relative to Randomized Controlled Trial Evidence in Australia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42288 Fri 19 Aug 2022 14:58:34 AEST ]]> Predictors and correlates of depression in retired elite level rugby league players https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47232 Fri 16 Dec 2022 12:08:56 AEDT ]]> No Evidence of the "Weekend Effect" in the Northern New South Wales Telestroke Network https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41805 Fri 12 Aug 2022 12:31:27 AEST ]]> Multimodal Computed Tomography Increases the Detection of Posterior Fossa Strokes Compared to Brain Non-contrast Computed Tomography https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41797 5 mL, the AUC was 0.87, 0.81, and 0.66, respectively.
