Aim: The aim of this study was to determine the predictive value of clinical presentations on functional ambulation following thrombolytic therapy. Materials & methods: Logistic regression analysis was used to determine associations between functional ambulation and thrombolytic therapy. Results & conclusion: In the results, Hispanic ethnicity (odds ratio (OR): 2.808; p = 0.034; 95% CI: 1.08–7.30), high National Institute of Health Stroke Scale (NIHSS) (OR: 1.112; p ≤ 0.001; 95% CI: 1.06–1.17), weakness/paresis (OR: 1.796; p = 0.005; 95% CI: 1.19–2.71), Broca’s aphasia (OR: 1.571; p = 0.003; 95% CI = 1.16–2.12) and antihypertensive medication (OR: 1.530; p = 0.034; 95% CI: 1.03–2.26) were associated with an improved ambulation in patients without thrombolytic therapy. In thrombolytic treated patients, Broca’s aphasia was associated with improved functional outcome.
Background. The purpose of this study was to develop models to predict the recovery of ambulatory functions taking into account the capability of the motor system to functionally reorganize in response to thrombolysis therapy. Methods. We predicted ambulatory functions recovery using retrospective data from a stroke registry of acute ischemic stroke patients who received thrombolysis therapy. Multivariate regression was used to construct the models. Multicollinearity and significant interactions were examined using variance inflation factors, while a Cox & Snell classification were applied to check the fitness of each model. Results. The models correctly predicted clinical variables that were associated with an improvement or non-improvement in functional ambulatory outcome. Broca’s aphasia (OR = 2.270, P = 0.002, CI =1.34-3.83) was associated with improved functional outcome at discharge, while patients aged 80 years or older (OR = 0.942, P = <0.001, CI =0.92-0.96), patients with congestive heart failure (OR = 0.496, P = 0.040, CI = 0.25-0.97), higher NIHSS (OR=0.876, P = 0.001, CI = 0.80-0.95), taking antihypertensive medication (OR = 0.436, P = 0.023, CI = 0.21-0.89) were not associated with improved ambulatory functional outcome with thrombolysis. The discriminating ability for the model was 74.2% for the total population, 71.7% for the rtPA group, and 72.2% for the no-rtPA group indicating strong performance. Conclusion. Prognostic models that can predict improved functional ambulatory outcome in thrombolysis therapy can be beneficial in the care of stroke patients. Our models predicted improved functional recovery of Broca’s aphasia after thrombolysis therapy, suggesting a future potential to evaluate motor speech area after stroke.
Eosinophilic colitis (EC) is the most uncommon disease within the spectrum of eosinophilic gastrointestinal disorders. Currently, there are no well-established diagnostic criteria and no approved Food and Drug Administration therapies. We discuss a case of a 30year-old man with refractory malignant EC leading to ischemic colitis. The patient was tried on multiple therapies, including a combination therapy of benralizumab and vedolizumab, which were unsuccessful. Unfortunately, the patient ultimately required a total proctocolectomy. More studies need to be performed to treat patients with severe refractory cases of EC.
Background. Specific clinical risk factors that may be associated with ambulatory outcome following thrombolysis therapy in ischemic stroke patients with pre-stroke depression is not fully understood. This was investigated. Methods. Multivariate analyses were performed to identify predictors of functional ambulatory outcomes. Patient demographics and clinical risk factors served as predictive variables, while improvement or no improvement in ambulatory outcome was considered as the primary outcome. Results. A total of 595 of these patients received rtPA of which 310 patients presented with pre-stroke depression, 217 had no improvement in functional outcome, while 93 patients presented with an improvement in functional outcome. Carotid artery stenosis (OR= 11.577, 95% CI, 1.281 – 104.636, P=0.029) and peripheral vascular disease (OR= 18.040, 95% CI, 2.956-110.086, P=0.002) were more likely to be associated with an improvement in ambulation. Antihypertensive medications (OR= 7.810, 95% CI, 1.401 –43.529, P=0.019),previous TIA (OR= 0.444, 95% CI, 0.517 –0.971, P=0.012), and congestive heart failure (OR= 0.217, 95% CI, 0.318 –0.402, P=0.030) were associated with a no improvement in ambulation. Conclusion. After adjustment for covariates, more clinical risk factors were associated with no improvement when compared with improvement in functional outcome following thrombolysis therapy in an acute ischemic stroke population with pre-stroke depression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
