<jats:sec><jats:title>Background</jats:title><jats:p> An indwelling urinary catheter (IUC) is often inserted to manage bladder dysfunction, but its impact on prognosis is uncertain. We aimed to determine the association of IUC use on clinical outcomes after acute stroke in the international, multi-center, cluster crossover, Head Positioning in Acute Stroke Trial (HeadPoST). </jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p> Data were analyzed on HeadPoST participants (n = 11,093) randomly allocated to the lying-flat or sitting-up head position. Binomial, logistic regression, hierarchical mixed models were used to determine associations of early insertion of IUC within seven days post-randomization and outcomes of death or disability (defined as “poor outcome,” scores 3–6 on the modified Rankin scale) and any urinary tract infection at 90 days with adjustment of baseline and post-randomization management covariates. </jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p> Overall, 1167 (12%) patients had an IUC, but the frequency and duration of use varied widely across patients in different regions. IUC use was more frequent in older patients, and those with vascular comorbidity, greater initial neurological impairment (on the National Institutes of Health Stroke Scale), and intracerebral hemorrhage as the underlying stroke type. IUC use was independently associated with poor outcome (adjusted odds ratio (aOR): 1.40, 95% confidence interval (CI): 1.13–1.74), but not with urinary tract infection after adjustment for antibiotic treatment and stroke severity at hospital separation (aOR: 1.13, 95% CI: 0.59–2.18). The number exposed to IUC for poor outcome was 13. </jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p> IUC use is associated with a poor outcome after acute stroke. Further studies are required to inform appropriate use of IUC. </jats:p></jats:sec>

<jats:sec> <jats:title>Background and Purpose—</jats:title> <jats:p>We aimed to determine associations of baseline blood glucose and diabetes mellitus with clinical outcomes in participants of the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT2).</jats:p> </jats:sec> <jats:sec> <jats:title>Methods—</jats:title> <jats:p>INTERACT2 was an international prospective, open, blinded end point, randomized controlled trial of 2839 patients with spontaneous intracerebral hemorrhage (<6 hours) and elevated systolic blood pressure randomly assigned to intensive (target systolic blood pressure <140 mm Hg) or guideline-based (systolic blood pressure <180 mm Hg) BP management. Associations of hyperglycemia at presentation (>6.5 mmol/L) and combined and separate poor outcomes of death and major disability (scores of 3–6, 3–5, and 6, respectively, on the modified Rankin scale) at 90 days were determined in logistic regression models.</jats:p> </jats:sec> <jats:sec> <jats:title>Results—</jats:title> <jats:p> In 2653 patients with available data, there were 1348 (61%) with hyperglycemia and 292 (11%) with diabetes mellitus. Associations of baseline blood glucose and poor outcome were strong and near continuous. After adjustment for baseline variables, the highest fourth (7.9–25.0 mmol/L) of blood glucose was significantly associated with combined poor outcome (adjusted odds ratio 1.35, 95% confidence interval 1.01–1.80; <jats:italic>P</jats:italic> trend 0.015). Diabetes mellitus also predicted poor outcome (adjusted odds ratio 1.46, 95% confidence interval 1.05–2.02; <jats:italic>P</jats:italic> =0.023), though more important for residual disability than death on separate analysis. </jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions—</jats:title> <jats:p>Hyperglycemia and diabetes mellitus are independent predictors of poor outcome in patients with predominantly mild to moderate severity of intracerebral hemorrhage. These data support guideline recommendations for good glycemic control in patients with intracerebral hemorrhage.</jats:p> </jats:sec> <jats:sec> <jats:title>Clinical Trial Registration—</jats:title> <jats:p> URL: <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://www.clinicaltrials.gov">http://www.clinicaltrials.gov</jats:ext-link> .

Dysphagia is associated with aspiration pneumonia after stroke. Data are limited on the influences of dysphagia screen and assessment in clinical practice. </jats:p></jats:sec><jats:sec><jats:title>Aims</jats:title><jats:p> To determine associations between a “brief” screen and “detailed” assessment of dysphagia on clinical outcomes in acute stroke patients. </jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p> A prospective cohort study analyzed retrospectively using data from a multicenter, cluster cross-over, randomized controlled trial (Head Positioning in Acute Stroke Trial [HeadPoST]) from 114 hospitals in nine countries. HeadPoST included 11,093 acute stroke patients randomized to lying-flat or sitting-up head positioning. Herein, we report predefined secondary analyses of the association of dysphagia screening and assessment and clinical outcomes of pneumonia and death or disability (modified Rankin scale 3–6) at 90 days. </jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p> Overall, 8784 (79.2%) and 3917 (35.3%) patients were screened and assessed for dysphagia, respectively, but the frequency and timing for each varied widely across regions. Neither use of a screen nor an assessment for dysphagia was associated with the outcomes, but their results were compared to “screen-pass” patients, those who failed had higher risks of pneumonia (adjusted odds ratio [aOR] = 3.00, 95% confidence interval [CI] = 2.18–4.10) and death or disability (aOR = 1.66, 95% CI = 1.41–1.95). Similar results were evidence for the results of an assessment for dysphagia. Subsequent feeding restrictions were related to higher risk of pneumonia in patients failed dysphagia screen or assessment (aOR = 4.06, 95% CI = 1.72–9.54). </jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p> Failing a dysphagia screen is associated with increased risks of pneumonia and poor clinical outcome after acute stroke. Further studies concentrate on determining the effective subsequent feeding actions are needed to improve patient outcomes.
