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 ]]> Management of Poststroke Hyperglycemia: Results of the TEXAIS Randomized Clinical Trial https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54324 Wed 28 Feb 2024 15:22:19 AEDT ]]> Reperfusion therapy in acute ischemic stroke: dawn of a new era? https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32816 Wed 02 Mar 2022 14:28:29 AEDT ]]> Most endovascular thrombectomy patients have Target Mismatch despite absence of formal CT perfusion selection criteria https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54333 1.8. The primary outcome was good functional outcome at 90 days, defined as a modified Rankin Scale (mRS) score 0-2. follow-up infarct volume, core expansion and penumbral salvage volumes were secondary outcomes. Of 572 anterior circulation EVT patients, CTP source image data required to generate objective maps were available in 170, and a Target Mismatch was present in 151 (89%). The rate of 90-day good functional outcome was similar between Target Mismatch (53%) and Large Core Non-Mismatch groups (46%, p = 0.629). Median follow-up infarct volume in the Large Core Non-Mismatch group (104ml [IQR 25ml-189ml]) was larger than that in the Target Mismatch patients (16ml [8ml-47ml], p<0.001). Despite a lack of formal CTP selection criteria, the majority of patients treated at our centres had a Target Mismatch. Patients without Target Mismatch had larger follow-up infarct volumes, but the functional recovery rate was similar to that in Target Mismatch patients. Infarct volumes should be included as objective assessment criteria in the evaluation of the efficacy of EVT in non-Target Mismatch patients.]]> Tue 20 Feb 2024 16:05:37 AEDT ]]> Comprehensive stroke units: a review of comparative evidence and experience https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18958 Sat 24 Mar 2018 07:58:56 AEDT ]]> Health service management study for stroke: a randomized controlled trial to evaluate two models of stroke care https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21244 P = 0·77 at discharge; co-located acute/rehabilitation stroke care: 109·5 ± 21·7 vs. traditionally separated acute/rehabilitation stroke care: 104·4 ± 27·9; P = 0·8875 at 90 days post-discharge). Total length of hospital stay was 5·28 days less in co-located acute/rehabilitation stroke care compared with traditionally separated acute/rehabilitation stroke care (24·15 ± 3·18 vs. 29·42 ± 4·5, P = 0·35). There was significant improvement in functional independence measure efficiency score among participants assigned to co-located acute/rehabilitation stroke care compared with traditionally separated acute/rehabilitation stroke care (co-located acute/rehabilitation stroke care: median 1·60, interquartile range: 0·87–2·81; traditionally separated acute/rehabilitation stroke care: median 0·82, interquartile range: 0·27–1·57, P = 0·0393). Linear regression analysis revealed a high inverse correlation (R² = 0·89) between functional independence measure efficiency and time spent in the acute stroke unit. Conclusion: This proof-of-concept study has shown that co-located acute/rehabilitation stroke care was just as effective as traditionally separated acute/rehabilitation stroke care as reflected in functional independence measure scores, but significantly more efficient as shown in greater functional independence measure efficiency. Co-located acute/rehabilitation stroke care has potential for significantly improved hospital bed utilization with no patient disadvantage.]]> Sat 24 Mar 2018 07:53:02 AEDT ]]> Comparison of functional outcomes after endovascular thrombectomy in patients with and without atrial fibrillation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41708 Fri 12 Aug 2022 08:09:28 AEST ]]>
