(1) Objective: This study aimed to construct a machine learning model for predicting the prognosis of ischemic stroke patients who underwent thrombolysis, assessed through modified Rankin Scale (mRS) score 90 days after discharge. (2) Methods: Data were sourced from Qatar’s registry covering January 2014 June 2022. A total 723 with had received thrombolysis included. Clinical variables examined, encompassing demographics, severity indices, comorbidities, laboratory results, admission vital...
Background Stroke is a significant global health burden and ranks as the second leading cause of death worldwide. Objective This study aims to develop evaluate machine learning-based predictive tool for forecasting 90-day prognosis stroke patients after discharge measured by modified Rankin Score. Methods The utilized data from large national multiethnic registry comprising 15,859 adult diagnosed with ischemic or hemorrhagic stroke. Of these, 7,452 satisfied study’s inclusion criteria....
Background Posterior cerebral circulation ischemic stroke (PCS) comprises up to 25% of all strokes. It is characterized by variable presentation, leading misdiagnosis and morbidity mortality. We aim describe PCS in large multiethnic cohorts. Methods A retrospective review a national database from its inception on the 1st January 2014 till 31 December 2020. Incidence per 100,000 adult population/year, demographics, clinical features, location, outcomes were retrieved. divided cohort into...
Timely recanalization improves long-term outcomes in acute ischemic stroke (IS) patients, but most patients present outside the therapeutic window. Emergency Medical Services (EMS) can reduce pre-hospital delay and increase likelihood of recanalization. We aim to determine characteristic variations amongst suspected using EMS. This retrospective observational study included all admitted a national tertiary care hospital Qatar from January 2014 September 2020. evaluated demographics, clinical...
ObjectivesPredicting stroke mortality is crucial for personalized care. This study aims to design and evaluate a machine learning model predict one-year after stroke.Materials methodsData from the National Multiethnic Stroke Registry was utilized. Eight (ML) models were trained evaluated using various metrics. SHapley Additive exPlanations (SHAP) analysis used identify influential predictors.ResultsAmong 9,840 patients diagnosed with stroke, XGBoost exhibited optimal performance high...
The presence of COVID-19 infection may increase the risk thrombotic events including ischemic strokes. Whilst a number recent reports suggest that associated stroke tends to be severe, there is limited data on effects in prospective registries.
Posterior Circulation Syndrome (PCS) presents a diagnostic challenge characterized by its variable and nonspecific symptoms. Timely accurate diagnosis is crucial for improving patient outcomes. This study aims to enhance the early of PCS employing clinical demographic data machine learning. approach targets significant research gap in field stroke management.
Corneal confocal microscopy can identify corneal nerve damage in patients with peripheral and central neurodegeneration. However, the use of presenting acute ischemic stroke is unknown.One hundred thirty (57 without diabetes mellitus [normal glucose tolerance], 32 impaired tolerance, 41 type 2 mellitus) admitted stroke, 28 age-matched healthy control participants underwent to quantify fiber density, branch length.There was a significant reduction length normal tolerance (P<0.001, P<0.001,...
Background Studies assessing the burden of stroke in Qataris are limited. We aim to study Qatari population. Methods A retrospective review was undertaken all adults presenting with Hamad Medical Corporation over a 5-year period. Descriptive statistics were used summarize demographic and other clinical characteristics patients. The primary outcome incidence Comparison made between sexes. Results 862 patients included, 58.9% being male. average period 92.04 per 100,000 adult mean age cohort...
Understanding the relationship of COVID-19 to stroke is important. We compare characteristics pre-pandemic historical (Pre-C), cases in acute COVID infection (Active-C) and patients who have recovered from (Post-C).We interrogated Qatar database for all admissions between Jan 2019 Feb 2020 (Pre-C) Active-C (Feb2020-Feb2021) Post-C determine how affected ischemic sub-types, clinical course, outcomes prior to, during post-pandemic peak. used modified Rankin Scale (mRS) measure outcome at...
Background Stroke is a major cause of death and disability worldwide presents significant burden on healthcare systems. This retrospective study aims to analyze the characteristics outcomes stroke patients admitted Hamad General Hospital (HGH) service in Qatar from January 2014 July 2022.
Background Atrial fibrillation is an important risk factor for stroke but there are limited data on atrial fibrillation-related from the Middle East. Methods We interrogated Qatar Stroke Database to establish occurrence, clinical features, and outcomes of at Hamad General Hospital, sole provider acute care in Qatar. Results A total 4079 patients (81.4% male, mean age 55.4 ± 13.3 years) were enrolled database between January 2014 21 October 2017. was present 260 (6.4%) patients, whom 106...
Several reports document a decrease in the rates of stroke hospital admissions during covid-19 pandemic. There is very little information whether admission will change as infection controlled. We report on our before, and following peak infections prospective database from Qatar.
Tuberculous meningitis is the severest and commonest form of central nervous system tuberculosis causing high mortality morbidity. We aim to study clinical, biochemical, radiological characteristics tuberculous in adult patients Qatar calculate incidence.A descriptive retrospective 7-year was conducted at Hamad General Hospital (the only tertiary referral center sole health care provider for Qatar) between 1st January 2006 31st December 2012, describe clinical presentation, diagnosis,...
<b><i>Background:</i></b> Sex differences may determine presentation, utility of treatment, rehabilitation, and occurrences major adverse cardiovascular events (MACEs) in acute stroke (AS). <b><i>Objective:</i></b>The purpose the study was to evaluate short-term prognosis long-term outcomes MACEs Qatari nationals admitted with AS. <b><i>Methods:</i></b> All AS patients between January 2014 February 2019 were included.
