Article Synopsis
  • Stroke-associated Hospital Acquired Pneumonia (HAP) is a serious concern for stroke patients, and this study investigates using machine learning to predict its occurrence based on national registry data.
  • The research involved analyzing data from nearly 10,000 stroke patients and comparing the performance of various machine learning models, with the Artificial Neural Network (ANN) achieving the best results.
  • Key predictors for HAP were identified through SHAP analysis, indicating that factors like stroke severity and arrival method significantly affect the risk of developing HAP, highlighting the potential for improved patient care through predictive modeling.

Article Synopsis
  • The study assesses the use of machine learning models to predict one-year mortality after an ischemic stroke, highlighting the importance of accurate predictions for personalized treatment strategies.
  • Logistic regression proved to be the most effective model, achieving an accuracy of 83% and identifying key factors like stroke severity, age, and pre-stroke functional status that influence mortality risk.
  • The findings suggest that early prediction of mortality can improve stroke care, though further research is necessary to validate the model across various clinical environments.

(1) Objective: This study aimed to construct a machine learning model for predicting the prognosis of ischemic stroke patients who underwent thrombolysis, assessed through the modified Rankin Scale (mRS) score 90 days after discharge. (2) Methods: Data were sourced from Qatar's stroke registry covering January 2014 to June 2022. A total of 723 patients with ischemic stroke who had received thrombolysis were included.

Purpose: To investigate the safety and effectiveness of rescue stent placement in patients who experienced acute stroke in whom mechanical thrombectomy failed.

Methods: This was a retrospective review of a multiethnic stroke database. After stent placement, an aggressive antiplatelet protocol was followed with glycoprotein IIb/IIIa infusion.

Article Synopsis
  • Histological structure of thrombi plays a key role in the effectiveness of recanalization therapies for acute ischemic stroke (AIS) patients, with a study analyzing 21 AIS patients.
  • Thrombi were predominantly platelet-rich, with only a small percentage containing red blood cells (RBCs), and exhibited distinct structural differences: RBC-rich areas had tightly packed RBCs and minimal von Willebrand factor (VWF), while platelet-rich areas featured thick fibrin networks, VWF, and numerous activated neutrophils.
  • The presence of neutrophil extracellular traps (NETs) was significant, as they were associated with VWF, platelets, and other inflammatory markers, indicating a complex interaction between these components in thrombus

Background: Acute stroke care is complex and requires multidisciplinary networking. There are insufficient data on stroke care in the Middle East and adjacent regions in Asia and Africa.

Objective: Evaluate the state of readiness of stroke programs in the Middle East North Africa and surrounding regions (MENA+) to treat acute stroke.

Background And Purpose: Uncertainty remains regarding the impact of enteric-coated aspirin (EC-ASA) on secondary prevention of ischemic stroke compared to plain aspirin (P-ASA). Hence, this study was designed to investigate the effect of EC formulation on ASA response via evaluating thromboxane B2 (TXB2) levels in patients with suspected or newly diagnosed stroke.

Methods: A prospective cohort study on suspected or newly diagnosed ischemic stroke patients who are aspirin-naive was conducted.

Atraumatic convexity subarachnoid hemorrhage (cSAH) is a rare non-aneurysmal SAH, commonly due to ipsilateral internal carotid artery (ICA) stenosis. It is unusual for the cSAH to occur contralaterally to the infarct. We report two cases of acute ischemic stroke associated with contralateral and ipsilateral cSAH that had different presentations.

Background And Purpose: Understanding the relationship of COVID-19 to stroke is important. We compare characteristics of pre-pandemic historical stroke (Pre-C), cases in acute COVID infection (Active-C) and in patients who have recovered from COVID-19 infection (Post-C).

Methods: We interrogated the Qatar stroke database for all stroke admissions between Jan 2019 and Feb 2020 (Pre-C) to Active-C (Feb2020-Feb2021) and Post-C to determine how COVID-19 affected ischemic stroke sub-types, clinical course, and outcomes prior to, during and post-pandemic peak.

Article Synopsis
  • Some people on airplanes are having strokes, and this is becoming an important issue to talk about.
  • Researchers studied patients who had strokes while traveling and compared them to those who didn’t travel.
  • They found that travelers with strokes were older and had more severe strokes, and they got treated more than those who stayed on the ground.

Article Synopsis
  • * After the peak, admissions increased to an average of 192 per month, but there were more severe cases of ischemic strokes and less functional recovery observed.
  • * The decline in admissions was largely due to a reduction in cases that were not actual strokes (stroke mimics), highlighting the need for further investigation into ongoing trends even after COVID-19 cases decline.

Understanding the relationship of COVID-19 to stroke is important. We compare characteristics of pre-pandemic stroke (PPS), cases in acute COVID infection (CS) and in patients who have recovered from COVID-19 infection (RCS). We interrogated the Qatar stroke database for all stroke admissions between Jan 2020 and Feb 2021 (PPS) to CS and RCS to determine how COVID-19 affected ischemic stroke sub-types, clinical course, and outcomes prior to, during and post-pandemic peak.

The use of steroids and other immune modulatory therapies in the treatment of severe COVID-19 pneumonia predisposes patients to the reemergence of opportunistic infections. (CMV) reactivation can be one of them. A 55-year-old gentleman with severe COVID-19 pneumonia and hypoxic respiratory failure who was ventilated and received steroids but no other immunomodulatory drugs; had altered sensorium and multiple episodes of seizures in the later course of his illness.
