Conclusions: Changes are observed on L-spine MRI after 6 months of ADT. Further investigation is warranted of MRS change as a potential predictive biomarker for later BMD loss.]]> Wed 04 Sep 2019 09:54:20 AEST ]]> Reperfusion facilitates reversible disruption of the human blood-brain barrier following acute ischaemic stroke https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36740 hypo-i), non-hypoperfused region of ischaemic hemisphere (rPSnonhypo-i) and their contralateral mirror regions (rPShypo-c and rPSnonhypo-c). The changes of rPS were analysed using analysis of variance (ANOVA) with repeated measures. Logistic regression was used to identify independent predictors of unfavourable outcome. Results: Fifty-six patients were included in the analysis, median age was 76 (IQR 62-81) years and 28 (50%) were female. From baseline to 24 h after treatment, rPShypo-i, rPSnonhypo-i and rPShypo-c all decreased significantly. The decreases in rPShypo-i and rPShypo-c were larger in the reperfusion group than non-reperfusion group. The rPShypo-i at follow-up was a predictor for unfavourable outcome (OR 1.131; 95% CI 1.018-1.256; P = 0.022). Conclusion: Early disruption of BBB in AIS is reversible, particularly when greater reperfusion is achieved. Elevated BBBP at 24 h after treatment, not the pretreatment BBBP, predicts unfavourable outcome. Key points: Early disruption of blood-brain barrier (BBB) in stroke is reversible after treatment; The reversibility of BBB permeability is associated with reperfusion; Unfavourable outcome is associated with BBB permeability at 24 h after treatment; Contralateral non-ischaemic hemisphere is not 'normal' during an acute stroke.]]> Thu 02 Jul 2020 16:31:45 AEST ]]>
