Background: Endovascular thrombectomy is the primary treatment for acute basilar artery occlusion (BAO), with direct aspiration (DA) and stent retriever (SR) as the main techniques. This updated meta-analysis aims to compare these two techniques in terms of efficacy and safety outcomes.

Methods: A search was performed across PubMed, Embase, and Cochrane databases on December 23, 2024.

Background: Retinal artery occlusion (RAO) is a vision-threatening condition with limited therapeutic options. Hyperbaric oxygen therapy (HBOT) has emerged as a potential treatment to enhance retinal oxygenation and salvage ischemic tissue, though its efficacy and safety remain debated.

Methods: We followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions.

Research plays a significant role in the residency match, particularly after the United States Medical Licensing Examination Step 1 changed from a score-based exam to pass/fail scoring. This study shows the impact of research on the match between 2009 and 2024, categorized by specialties and residency competitiveness. Residency specialties were categorized according to competitiveness (high, medium, and low), according to the Association of American Medical Colleges.

Background And Purpose: Acute ischemic stroke (AIS) is a leading cause of disability worldwide. While intravenous thrombolysis is recommended within 4.5 hours of last known well (LKW) time, many patients present beyond this window.

Acute bacterial meningitis (ABM) remains a common disease, especially in developing countries. Although morbidity and mortality have improved with advances in medicine, significant neurologic complications of meningitis still occur. Delayed cerebral vasculopathy (DCV) is a unique complication following ABM leading to ischemic strokes and poor functional outcomes.

Background: Endovascular thrombectomy (EVT) is the gold standard for eligible acute ischemic stroke (AIS) patients with large vessel occlusion (LVO). A few trials studied EVT in AIS-LVO with large ischemic infarcts. We investigated the impact of intravenous thrombolysis (IVT) on EVT outcomes in those patients.

Endovascular thrombectomy (EVT) is the standard treatment for acute ischemic stroke (AIS) caused by large vessel occlusion (LVO). Transradial access (TRA) has emerged as an alternative to traditional transfemoral access (TFA), showing promise in reducing access-site complications. This systematic review and meta-analysis aim to comprehensively assess the procedural and clinical outcomes of TRA versus TFA for EVT in AIS-LVO patients.

Background: Chronic subdural hematoma (cSDH) is a common neurosurgical condition with high recurrence rates, particularly in elderly patients. The pathophysiology involves complex mechanisms of angiogenesis, fibrinolysis, and inflammation, leading to progressive hemorrhage and fluid accumulation.

Aim: To systematically review and meta-analyze the clinical benefits and safety of middle meningeal artery embolization (MMAE) as an adjunctive treatment to usual care for cSDH.

Global disparities in stroke care, particularly in acute interventions like mechanical thrombectomy (MT), remain profound, with the Mechanical Thombectomy Global Access for Stroke study reporting a median global MT access of just 2.79%. Furthermore, the low- and middle-income countries (LMICs) have been recognized to be disproportionately burdened in this regard as compared with high-income countries.

Background: Endovascular thrombectomy (EVT) is the gold standard treatment for acute ischemic stroke (AIS) patients with large vessel occlusion (LVO). Multiple factors can influence EVT outcomes, including procedural and patient-related variables. This meta-analysis investigated the impact of periprocedural hemoglobin (Hb) levels on EVT outcomes.

Background: Endovascular thrombectomy (EVT) is the gold standard for acute ischemic stroke (AIS) with large vessel occlusion (LVO). However, concomitant intracranial hemorrhage (ICH) might render AIS-LVO patients ineligible for EVT in real-life practice.

Objective: To provide robust evidence regarding the outcomes of EVT in AIS-LVO patients with concomitant ICH.

Background: Chronic subdural hematoma (cSDH) is increasingly prevalent in the elderly and traditionally treated with surgical interventions. Middle meningeal artery embolization (MMAE) has emerged as an adjunctive therapy to reduce recurrence rates. Transfemoral access (TFA) is the conventional route for neuroendovascular procedures, but transradial access (TRA) offers potential advantages, including reduced access-site complications, earlier ambulation, and shorter hospital stays.

Article Synopsis
  • Preventing rebleeding in aneurysmal subarachnoid hemorrhage (SAH) is important, and lowering systolic blood pressure (SBP) may help, although evidence is not clear-cut.
  • A systematic review analyzed ten studies, finding that higher SBP is linked to a greater chance of rebleeding, while maintaining SBP ≤160 mmHg reduced this risk significantly.
  • The results should be approached cautiously due to variability in study designs, highlighting the need for more standardized future research to better understand blood pressure's role in rebleeding risk.

Article Synopsis
  • * A review highlights the connection between PD, new-onset seizures, and pyridoxine deficiency, using case reports that show seizures often occur with high-dose dopaminergic therapy and underlying vitamin deficiencies, despite other tests returning normal results.
  • * The study emphasizes the importance of monitoring pyridoxine levels in PD patients, particularly those experiencing dietary issues or undergoing significant medication changes, to improve patient care and quality of life by potentially reducing seizure risks.

Background: Aneurysmal subdural hematoma (aSDH) is a rare complication of aneurysm rupture, affecting between 0.5 and 7.9% of patients with aneurysmal subarachnoid hemorrhage (aSAH).

Article Synopsis
  • This study aimed to assess how cerebral microbleeds (CMBs) affect outcomes for stroke patients undergoing endovascular thrombectomy (EVT), focusing on functional independence and safety.
  • Using a systematic review approach, researchers analyzed four studies with 1,514 patients and found that the presence of CMBs significantly reduced the chances of achieving positive functional outcomes after EVT.
  • However, CMBs had no effect on successful revascularization rates, mortality, or the occurrence of various hemorrhagic complications, indicating a specific impact of CMBs on functional recovery rather than overall safety.

In the field of cell death, there is still a wide gap between the molecular models and their ultrastructural phenotypes. Because only very few published works included electron microscopy (EM) images, many ultrastructural features have not yet been incorporated into the descriptions of death modes. Some of the EM features that appear in dying cells have not been incorporated in describing death modes.
