Safety and Efficacy of Intravenous Thrombolysis by Infarct Type in Patients with No Visible Occlusion: A Secondary Analysis of the AcT Trial.

Background: About 25% of patients with acute ischemic stroke have lacunar infarct on follow-up imaging. In this secondary analysis from the AcT (Alteplase Compared With Tenecteplase) trial, we assessed if there is variation in safety or efficacy of intravenous thrombolysis by infarct type in patients with no visible occlusion. We also determined if this effect differed between tenecteplase and alteplase.

Tenecteplase Versus Alteplase in Medium Vessel Occlusion Ischemic Stroke: A Secondary Analysis of the Alteplase Compared to Tenecteplase Randomized Trial.

Background And Purpose: The safety and efficacy of tenecteplase in patients with ischemic stroke due to medium vessel occlusion (MeVO) are not well studied. We aimed to compare tenecteplase with alteplase in stroke due to MeVO.

Methods: Patients with baseline M2-middle cerebral artery (MCA), M3/M4-MCA, P2/P3/P4-posterior cerebral artery (PCA), A2/A3/A4-anterior cerebral artery (ACA) occlusions from the Alteplase Compared to Tenecteplase (AcT) trial were included.

Prevalence of depression and anxiety symptoms after stroke in young adults: A systematic review and meta-analysis.

Background: Young adults with stroke have distinct professional and social roles making them vulnerable to symptoms of post-stroke depression (PSD) and post-stroke anxiety (PSA). Prior reviews have examined the prevalence of anxiety and depression in stroke populations. However, there are a lack of studies that have focused on these conditions in young adults.

Nonaneurysmal perimesencephalic subarachnoid hemorrhage on noncontrast head CT: An accuracy, inter-rater, and intra-rater reliability study.

Background And Purpose: To evaluate the reliability and accuracy of nonaneurysmal perimesencephalic subarachnoid hemorrhage (NAPSAH) on Noncontrast Head CT (NCCT) between numerous raters.

Materials And Methods: 45 NCCT of adult patients with SAH who also had a catheter angiography (CA) were independently evaluated by 48 diverse raters; 45 raters performed a second assessment one month later. For each case, raters were asked: 1) whether they judged the bleeding pattern to be perimesencephalic; 2) whether there was blood anterior to brainstem; 3) complete filling of the anterior interhemispheric fissure (AIF); 4) extension to the lateral part of the sylvian fissure (LSF); 5) frank intraventricular hemorrhage; 6) whether in the hypothetical presence of a negative CT angiogram they would still recommend CA.

Perfusion vs non-perfusion computed tomography imaging in the late window of emergent large vessel ischemic stroke: A systematic review and meta-analysis.

Background: Guidelines recommend the treatment of emergent large vessel ischemic stroke (ELVIS) patients presenting beyond 6 hours of last known well time with endovascular thrombectomy (EVT) based on perfusion computed tomography (CT) neuroimaging. We compared the outcomes (long-term good clinical outcomes, symptomatic intracranial hemorrhage (sICH), and mortality) of ELVIS patients according to the type of CT neuroimaging they underwent.

Methods: We searched the following databases: Medline, Embase, CENTRAL, and Scopus from January 1, 2015, to June 14, 2023.

Missed pituitary microadenoma during endoscopic transsphenoidal surgery for short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing with symptom relief: illustrative case.

Background: Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a rare headache disorder that has been associated with pituitary adenomas. Resection has been posited to be curative.

Observations: A 60-year-old female presented with a 10-year history of SUNCT, which had been medically refractory.

Patient-reported intraoperative experiences during awake craniotomy for brain tumors: a scoping review.

Awake craniotomy (AC) is a neurosurgical procedure that may be used to excise tumors located in eloquent areas of the brain. The techniques and outcomes of AC have been extensively described, but data on patient-reported experiences are not as well known. To determine these, we performed a scoping review of patient-reported intraoperative experiences during awake craniotomy for brain tumor resection.

A meta-analysis on the prevalence of anxiety and depression in patients with unruptured intracranial aneurysms: exposing critical treatment gaps.

Unruptured intracranial aneurysms (UIAs) are a significant cause of anxiety and depression. Though the annual rupture rate is relatively low, ensuing mortality and morbidity may be high. Most published studies have focused on functional outcomes; however, limited studies have explored and reported on psychiatric outcomes, which are equally important.

Predictive Value of Hematologic Inflammatory Markers in Delayed Cerebral Ischemia After Aneurysmal Subarachnoid Hemorrhage.

Background And Objective: Our study aimed to determine the ability of hematologic markers (neutrophil/lymphocyte ratio [NLR], platelet/lymphocyte ratio, and red cell distribution width [RDW]) in predicting delayed cerebral ischemia (DCI), modified Rankin Scale scores, and mortality in patients with aneurysmal subarachnoid hemorrhage (aSAH).

Methods: A retrospective observational 6-year review of medical records was conducted to identify all consecutive patients with aSAH admitted to the largest training hospital in the Philippines. Univariable and multivariable regression analyses were performed to determine the association of the biomarkers with the respective outcomes.

Practice Patterns in Surgical Neuro-Oncology Among Low- and Middle-Income Countries During the Coronavirus Disease 2019 Pandemic: A Scoping Review and Situational Report from the Philippines.

Background: The coronavirus disease 2019 (COVID-19) pandemic has negatively affected the outcomes of surgical neuro-oncology patients worldwide. We aimed to review the practice patterns in surgical neuro-oncology in low- and middle-income countries (LMICs). We also present a situational report from our own country.

Intraoperative radiotherapy for glioblastoma: A systematic review of techniques and outcomes.

Background: Despite multimodality treatment, the prognosis of glioblastoma (GBM) has remained poor. Intraoperative radiation therapy (IORT) offers additional local control by directly applying a radiation source to the resection margin, where most recurrences occur.

Methods: We performed a systematic review on the oncologic outcomes and toxicities of IORT for GBM in the era of modern external beam radiation therapy (EBRT) and chemotherapy with temozolamide.
