The Alberta Stroke Program Early Computed Tomography Score (ASPECTS) has not been previously applied to perfusion CT (CTP). Five raters assigned ASPECTS to baseline noncontrast CT (NCCT), CT angiography source images (CTA-SI), CTP source images (CTP-SI), and CTP maps of cerebral blood volume (CBV), cerebral blood flow (CBF), and mean transit time (MTT) from 37 consecutive patients with less than 6-hour anterior circulation ischemic stroke. Major reperfusion was identified on follow-up imaging. Mean baseline ASPECTS was compared with follow-up imaging ASPECTS. Rates of favorable outcome were compared for dichotomized baseline ASPECTS. In patients with major reperfusion, mean CBV and CTP-SI ASPECTS closely predicted final infarct ASPECTS. In patients without major reperfusion, mean CBF and MTT ASPECTS best predicted final infarct ASPECTS. There were significant increases in rates of favorable outcome for CTP-SI and CBV ASPECTS of greater than 6, versus less than or equal to 6, but not for other baseline CT modalities. ASPECTS applied to CTP is more accurate at identifying the extent of reversible and irreversible ischemia and at predicting final clinical outcome than NCCTor CTA-SI.

Isolated focal swelling identifies penumbral tissue and parenchymal hypoattenuation identifies infarct core. Although this has prognostic implications when assessing patient suitability for thrombolytic therapy, the majority of acutely hypoperfused regions appear normal on noncontrast CT. Perfusion CT can stratify the level of risk of subsequent infarction for normal-appearing regions on noncontrast CT.

BackgroundTrials of fluoxetine for recovery after stroke report conflicting results. The Assessment oF FluoxetINe In sTroke recoverY (AFFINITY) trial aimed to determine if daily fluoxetine for 6 months after stroke improves functional outcome in Australasian and Vietnamese patients. MethodsAFFINITY was a randomised, parallel-group, double-blind, placebo-controlled trial conducted in 43 hospital stroke units in Australia (n=29), New Zealand (4), and Vietnam (10). Eligible patients were adults with a clinical diagnosis of stroke in the previous 2-15 days and a persisting neurological deficit. Patients were randomised via a web-based system using a minimisation algorithm to once daily, oral fluoxetine 20mg or matching placebo for 6 months. Patients, investigators and outcome assessors were masked to the treatment allocation. The primary outcome was functional outcome, measured by the modified Rankin scale (mRS), at 6 months. The primary analysis was an ordinal logistic regression of the mRS at 6 months, adjusted for minimisation variables. Analyses were according to the patient's treatment allocation. The trial is registered with the ACTRN registry, number 12611000774921. FindingsPowered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation 1280 patients were recruited in Australia (n=532), New Zealand (n=42) and Vietnam (n=706) between 11 January 2013 and 30 June 2019; 642 were allocated fluoxetine and 638 placebo. Adherence to trial medication (mean 167 [SD 48] days) was similar between groups. At 6 months, mRS data were available in 624 (97.2%) patients allocated fluoxetine and 632 (99.1%) placebo. The distribution of mRS categories at 6 months was similar in the fluoxetine and placebo groups (adjusted common odds ratio 0.936, 95% CI 0.762-1.150; p=0.53), and consistent among all pre-defined subgroups. Compared to placebo, patients allocated fluoxetine had more falls (20 [3.12%] vs 7 [1.10%]; p=0.02), bone fractures (19 [2•96%] vs 6 [0.94%]; p=0.01) and epileptic seizures (10 [1.56%] vs 2 [0.31%]; p=0.04) at 6 months. InterpretationFluoxetine 20mg daily for 6 months after acute stroke did not improve functional outcome and increased the risk of falls, bone fractures, and seizures. These results do not support the use of fluoxetine to improve outcome after stroke.

Core advanced training jobs in neurology vary considerably across Australia, largely for historical reasons. This situation is suboptimal for many reasons. Training jobs ideally need to be modified to take into account the changing needs of trainees rather than just the service requirements of the various departments, but there are many resource issues involved in achieving this.

CollaborationIMPORTANCE One in 3 adults experiences clinically significant symptoms of depression during the first year after a stroke, but evidence to support the use of antidepressants in this population remains scant.OBJECTIVE To investigate whether daily treatment with 20 mg of fluoxetine hydrochloride reduces the proportion of people affected by clinically significant symptoms of depression after stroke. DESIGN, SETTING, AND PARTICIPANTSIn this secondary analysis of the Assessment of Fluoxetine in Stroke Recovery parallel-group, randomized (1:1 assignment), double-blind, placebo-controlled clinical trial, 1221 participants in Australia, New Zealand, and Vietnam were recruited between January 11, 2013, and June 30, 2019, and were followed up for 6 months. Adults aged 18 years or older were recruited 2 to 15 days after experiencing a stroke associated with modified Rankin Scale score of 1 or higher.INTERVENTIONS Fluoxetine hydrochloride, 20 mg, or matched placebo daily for 26 weeks. MAIN OUTCOMES AND MEASURESA 9-item Patient Health Questionnaire (PHQ-9) score of 9 or lower was a prespecified secondary outcome of the trial. Assessments were completed at baseline and at 4, 12, and 26 weeks. Other outcomes of interest included participant-reported clinician diagnosis of depression, prescription of a nontrial antidepressant, or nonpharmacologic treatment of depression. Analysis was on an intention-to-treat basis.RESULTS A total of 607 participants (378 men [62.3%]; mean [SD] age, 64.3 [12.2] years) were randomly assigned treatment with placebo, and 614 participants (397 men [64.7%]; mean [SD] age, 63.4 [12.4] years) were randomly assigned treatment with 20 mg of fluoxetine hydrochloride daily. The groups were balanced for demographic and clinical measures. At baseline, 112 patients (18.5%) in the placebo group and 116 patients (18.9%) in the fluoxetine group had PHQ-9 scores of 9 or higher. During follow-up, 126 of 596 participants (21.1%) treated with placebo and 121 of 598 participants (20.2%) treated with fluoxetine had PHQ-9 scores of 9 or higher (P = .70). A similar proportion of participants with PHQ-9 scores less than 9 at baseline who were treated with fluoxetine hydrochloride and placebo developed PHQ-9 scores of 9 or higher during the trial (placebo, 72 of 488 [14.8%]; and fluoxetine, 63 of 485 [13.0%]; P = .43). A slightly higher number of participants in the placebo group than in the fluoxetine group had a participant-reported clinician diagnosis of depression (42 of 602 [7.0%] vs 26 of 601 [4.3%]; P = .05). By week 26, 14 participants (2.3%) in the placebo group and 12 participants (1.9%) in the fluoxetine group had died (P = .67). CONCLUSIONS AND RELEVANCERoutine daily treatment with 20 mg of fluoxetine did not decrease the proportion of people affected by clinically significant symptoms of depression after a stroke, nor did it affect the proportion of people prescribed an antidepressant or receiving nonpharmacologic treatments compared with placebo.

Stroke is one of the leading causes of death and disability and it is more likely to occur in those who are older. Because people are living longer, the definition of "old" continues to evolve. Age alone should not influence the healthcare that a patient receives, however, evidence indicates that this does occur, especially in older patients. On the basis of the available evidence, it is time to reconsider whether or not stroke care should differ in older survivors of stroke and if so, why. This is a narrative review of stroke-related health care in those with a recent ischemic stroke. It seeks to answer the following question: Should patients aged ≥80 years who have experienced a recent ischemic stroke receive standard care or something different, and if they should receive something different, what should they receive and why? The review focusses on long-term survival, hyper-acute care, secondary prevention, and rehabilitation. The authors propose a number of recommendations in relation to stroke care in older survivors of a recent ischemic stroke.
