- There is concern that blood pressure (BP) lowering in acute stroke may compromise cerebral perfusion and worsen outcome in the presence of carotid stenosis. We assessed the effect of glyceryl trinitrate (GTN) in patients with carotid stenosis using data from the Efficacy of Nitric Oxide in Stroke (ENOS) Trial.MethodsENOS randomised 4011 patients with acute stroke and raised systolic BP (140–220 mm Hg) to transdermal GTN or no GTN within 48 hours of onset. Those on prestroke antihypertensives were also randomised to stop or continue their medication for 7 days. The primary outcome was the modified Rankin Scale (mRS) at day 90. Ipsilateral carotid stenosis was split: <30%; 30–<50%; 50–<70%; ≥70%. Data are ORs with 95% CIs adjusted for baseline prognostic factors.Results2023 (60.5%) ischaemic stroke participants had carotid imaging. As compared with <30%, ≥70% ipsilateral stenosis was associated with an unfavourable shift in mRS (worse outcome) at 90 days (OR 1.88, 95% CI 1.44 to 2.44, p<0.001). Those with ≥70% stenosis who received GTN versus no GTN had a favourable shift in mRS (OR 0.56, 95% CI 0.34 to 0.93, p=0.024). In those with 50–<70% stenosis, continuing versus stopping prestroke antihypertensives was associated with worse disability, mood, quality of life and cognition at 90 days. Clinical outcomes did not differ across bilateral stenosis groups.ConclusionsFollowing ischaemic stroke, severe ipsilateral carotid stenosis is associated with worse functional outcome at 90 days. GTN appears safe in ipsilateral or bilateral carotid stenosis, and might improve outcome in severe ipsilateral carotid stenosis.

- High blood pressure is common in acute stroke and associated with a worse functional outcome. Many patients who present with acute stroke are taking prescribed antihypertensive therapy before their stroke. Aims ENOS tested whether lowering blood pressure and continuing pre-stroke antihypertensive therapy are each safe and effective. Methods This study is an international multi-centre prospective randomized single-blind blinded-endpoint parallel-group partial-factorial controlled trial of transdermal glyceryl trinitrate (a nitric oxide donor, given for seven-days) vs. no glyceryl trinitrate, and of continuing vs. stopping (temporarily for seven-days) pre-stroke antihypertensive drugs if relevant, in patients with acute ischaemic stroke or intracerebral haemorrhage and high systolic blood pressure (140–220 mmHg). Results Recruitment ran from July 2001 to October 2013. Four thousand eleven patients [2097 (52·3%) in the continue/stop arm] were recruited from 173 sites across 23 countries in 5 continents (Asia 14%, Continental Europe 16%, UK 64%). Baseline characteristics include: mean age 70 (standard deviation 12) years; male 57%; mean time from stroke to recruitment 26 ( 13 ) h; mean severity (Scandinavian Stroke Scale) 34 ( 13 ) of 58; mean blood pressure 167 ( 19 )/90 ( 13 ) mmHg; ischaemic stroke 83%; and intracerebral haemorrhage 16%. The main trial results will be presented in May 2014. The results will also be presented in updated Cochrane systematic reviews and included in individual patient data meta-analyses of all relevant randomized controlled trials. Conclusion ENOS is a large completed international trial of blood pressure management in acute stroke and includes patients representative of many stroke services worldwide.

- Stroke rehabilitation interventions are routinely personalized to address individuals’ needs, goals, and challenges based on evidence from aggregated randomized controlled trials (RCT) data and meta-syntheses. Individual participant data (IPD) meta-analyses may better inform the development of precision rehabilitation approaches, quantifying treatment responses while adjusting for confounders and reducing ecological bias. Aim: We explored associations between speech and language therapy (SLT) interventions frequency (days/week), intensity (h/week), and dosage (total SLT-hours) and language outcomes for different age, sex, aphasia severity, and chronicity subgroups by undertaking prespecified subgroup network meta-analyses of the RELEASE database. Methods: MEDLINE, EMBASE, and trial registrations were systematically searched (inception-Sept2015) for RCTs, including ⩾ 10 IPD on stroke-related aphasia. We extracted demographic, stroke, aphasia, SLT, and risk of bias data. Overall-language ability, auditory comprehension, and functional communication outcomes were standardized. A one-stage, random effects, network meta-analysis approach filtered IPD into a single optimal model, examining SLT regimen and language recovery from baseline to first post-intervention follow-up, adjusting for covariates identified a-priori. Data were dichotomized by age (⩽/> 65 years), aphasia severity (mild–moderate/ moderate–severe based on language outcomes’ median value), chronicity (⩽/> 3 months), and sex subgroups. We reported estimates of means and 95% confidence intervals. Where relative variance was high (> 50%), results were reported for completeness. Results: 959 IPD (25 RCTs) were analyzed. For working-age participants, greatest language gains from baseline occurred alongside moderate to high-intensity SLT (functional communication 3-to-4 h/week; overall-language and comprehension > 9 h/week); older participants’ greatest gains occurred alongside low-intensity SLT (⩽ 2 h/week) except for auditory comprehension (> 9 h/week). For both age-groups, SLT-frequency and dosage associated with best language gains were similar. Participants ⩽ 3 months post-onset demonstrated greatest overall-language gains for SLT at low intensity/moderate dosage (⩽ 2 SLT-h/week; 20-to-50 h); for those > 3 months, post-stroke greatest gains were associated with moderate-intensity/high-dosage SLT (3–4 SLT-h/week; ⩾ 50 hours). For moderate–severe participants, 4 SLT-days/week conferred the greatest language gains across outcomes, with auditory comprehension gains only observed for ⩾ 4 SLT-days/week; mild–moderate participants’ greatest functional communication gains were associated with similar frequency (⩾ 4 SLT-days/week) and greatest overall-language gains with higher frequency SLT (⩾ 6 days/weekly). Males’ greatest gains were associated with SLT of moderate (functional communication; 3-to-4 h/weekly) or high intensity (overall-language and auditory comprehension; (> 9 h/weekly) compared to females for whom the greatest gains were associated with lower-intensity SLT (< 2 SLT-h/weekly). Consistencies across subgroups were also evident; greatest overall-language gains were associated with 20-to-50 SLT-h in total; auditory comprehension gains were generally observed when SLT > 9 h over ⩾ 4 days/week. Conclusions: We observed a treatment response in most subgroups’ overall-language, auditory comprehension, and functional communication language gains. For some, the maximum treatment response varied in association with different SLT-frequency, intensity, and dosage. Where differences were observed, working-aged, chronic, mild–moderate, and male subgroups experienced their greatest language gains alongside high-frequency/intensity SLT. In contrast, older, moderate–severely impaired, and female subgroups within 3 months of aphasia onset made their greatest gains for lower-intensity SLT. The acceptability, clinical, and cost effectiveness of precision aphasia rehabilitation approaches based on age, sex, aphasia severity, and chronicity should be evaluated in future clinical RCTs.

- <i>Background:</i> Aphasia affects one third of acute stroke patients. There is a considerable spontaneous recovery in aphasia, but impaired communication ability remains a great problem. Communication difficulties are an impediment to rehabilitation. Early treatment of the language deficits leading to increased communication ability would improve rehabilitation. The aim of this study is to elucidate the efficacy of very early speech and language therapy (SLT) in acute stroke patients with aphasia. <i>Methods:</i> A prospective, open, randomized, controlled trial was carried out with blinded endpoint evaluation of SLT, starting within 2 days of stroke onset and lasting for 21 days. 123 consecutive patients with acute, first-ever ischemic stroke and aphasia were randomized. The SLT treatment was Language Enrichment Therapy, and the aphasia tests used were the Norsk grunntest for afasi (NGA) and the Amsterdam-Nijmegen everyday language test (ANELT), both performed by speech pathologists, blinded for randomization. <i>Results:</i> The primary outcome, as measured by ANELT at day 21, was 1.3 in the actively treated patient group and 1.2 among controls. NGA led to similar results in both groups. Patients with a higher level of education (>12 years) improved more on ANELT by day 21 than those with <12 years of education (3.4 vs. 1.0, respectively). In 34 patients in the treatment group and 19 in the control group improvement was ≧1 on ANELT (p < 0.05). There was no difference in the degree of aphasia at baseline except for fluency, which was higher in the group responding to treatment. <i>Conclusions:</i> Very early intensive SLT with the Language Enrichment Therapy program over 21 days had no effect on the degree of aphasia in unselected acute aphasic stroke patients. In aphasic patients with more fluency, SLT resulted in a significant improvement as compared to controls. A higher educational level of >12 years was beneficial.

- <i>Background and Purpose:</i> Pharmacotherapy aimed at stroke rehabilitation through direct central nervous effects may be assumed to work in a similar way for language recovery and sensory-motor recovery. Some data suggest that antidepressant drugs could be beneficial also for functional improvement. This prompted us to investigate whether regression from aphasia after acute stroke could be enhanced by antidepressive drug therapy. <i>Methods:</i> We randomised 90 acute stroke patients with aphasia to either 600 mg moclobemide or placebo daily for 6 months, within 3 weeks of the onset of stroke. Aphasia was assessed prior to treatment and at 6 months, using Reinvang’s ‘Grunntest for afasi’ and the Amsterdam-Nijmegen-Everyday-Language-Test (ANELT). <i>Result:</i> The degree of aphasia decreased significantly at 6 months, with no difference between the moclobemide- and the placebo-treated groups. Multivariate regression analysis including treatment group, activities of daily living, aetiology of stroke, ANELT, and Reinvang’s coefficient at baseline, and neurological deficit confirmed these results. In all, 13 in the moclobemide and 10 in the placebo group stopped taking the study medication. No further change was found in the 56 aphasic patients followed up for another 6 months with no medication. <i>Conclusions:</i> Compared to placebo, treatment with moclobemide for 6 months did not enhance the regression of aphasia following an acute stroke.

- <i>Background:</i> Data on post-stroke depression in aphasia are scarce. <i>Methods:</i> Eighty-nine acute stroke patients with aphasia of all types were followed for 6 months to investigate if depression can be reliably diagnosed (DSM-IV criteria) and validly assessed by the verbal Montgomery-Åsberg Depression Rating Scale (MADRS) and a global technique (Clinical Global Impressions Rating Scale for Severity). A standard aphasia test was performed. <i>Results:</i> In 60 patients (67%) at baseline and in 100% at 6 months, comprehension allowed a reliable DSM-IV diagnosis. Among these patients MADRS was feasible in 95% at baseline and in 100% at 6 months. The assistance of relatives and staff increases the feasibility and decreases the validity. Depression was identified in 24% during the 6 months. <i>Conclusion:</i> Depression diagnosis and severity rating can reliably be made in the acute phase in at least two thirds of aphasic patients, and feasibility increases over time.
