Background: Acute ischemic stroke (AIS) is a leading cause of mortality and long-term disability worldwide, with upper-middle-income countries (UMICs) facing a disproportionate burden due to systemic inefficiencies in healthcare delivery. Kazakhstan reports the highest global age-standardized mortality rate from ischemic stroke, underscoring the need to evaluate current stroke care practices and identify areas for improvement. Objective: This study aimed to assess the current state of acute ischemic stroke care in Kazakhstan by examining key time metrics, protocol adherence, and the utilization of advanced technologies such as artificial intelligence (AI) and telemedicine. Additionally, this study sought to identify regional disparities in care and propose actionable recommendations to improve patient outcomes. Methods: A multi-center cross-sectional survey was conducted across 79 stroke centers in Kazakhstan. Data were collected from 145 healthcare professionals, including neurologists, neurosurgeons, and interventional radiologists, through a validated 23-question online questionnaire. Statistical analysis was performed to identify significant associations between variables. Results: Significant regional disparities were observed in stroke care timelines and technology adoption. Remote and rural areas experienced prolonged prehospital delays, with transport times ranging from 120 to 180 min, contributing to door-to-needle times exceeding the recommended benchmark. Urban centers with higher adoption of AI and telemedicine demonstrated faster treatment initiation and better protocol compliance. Staff training was significantly associated with improved treatment outcomes, with trained centers more likely to implement direct-to-angiography suite protocols, reducing in-hospital delays. Conclusions: Addressing acute ischemic stroke care disparities in Kazakhstan requires a multifaceted approach, including expanding AI and telemedicine, implementing targeted staff training programs, and establishing standardized national stroke protocols. These strategies can help reduce treatment delays, bridge the urban–rural healthcare divide, and improve patient outcomes. The findings have implications for other UMICs facing similar challenges in delivering equitable stroke care.

Background High-grade gliomas (HGGs) are aggressive brain tumors with poor prognoses. Maximizing the extent of resection (EOR) is a critical surgical goal. Fluorescence-guided surgery using 5-aminolevulinic acid (5-ALA) has been proposed to enhance tumor visualization and resection. MethodsWe retrospectively analyzed 141 patients with histologically confirmed HGGs who underwent either 5-ALA-guided (n = 71) or conventional white-light (n = 70) resection between 2018 and 2023. Propensity score matching and multivariate Cox regression models were used to assess the impact of 5-ALA on surgical outcomes and survival. Results: Gross total resection (GTR) was significantly more common in the 5-ALA group than the conventional white-light group (28.17% vs. 12.86%, p = 0.0245). Kaplan–Meier analysis showed no statistically significant difference in overall survival between groups after matching (log-rank p = 0.6371). However, patients with GTR had significantly improved survival compared to those with subtotal resection (log-rank p = 0.0423). Multivariate Cox regression identified radiotherapy (HR = 0.291, 95% CI: 0.166–0.513, p < 0.001), higher Karnofsky Performance Status (HR = 0.962, 95% CI: 0.942–0.982, p = 0.0003), and GTR (HR = 0.476, 95% CI: 0.272–0.834, p = 0.0091) as independent predictors of improved survival. 5-ALA usage was not an independent predictor (HR = 0.885, 95% CI: 0.554–1.413, p = 0.612). Radiotherapy and chemotherapy were more frequently administered in the conventional white-light group (p = 0.0404 and p = 0.0085, respectively). Conclusions 5-ALA fluorescence-guided surgery significantly increases the rate of gross total resection in high-grade glioma patients but does not independently confer a survival advantage. Survival outcomes are primarily influenced by the extent of resection, adjuvant therapy, and functional status. Integration of 5-ALA within a comprehensive oncological framework may enhance its clinical utility.

Background/Objectives: Intracranial atherosclerosis (ICAS) is a major cause of ischemic stroke, disproportionately affecting populations with significant vascular risk factors. Although ICAS imposes a considerable health burden, research on this condition in Central Asia remains scarce, especially among the Kazakh population. This study analyzes demographic characteristics, treatment outcomes, and procedural challenges associated with ICAS in 216 patients treated at a single institution. Methods: This retrospective study included patients with ≥70% intracranial artery stenosis confirmed by imaging and presenting with ischemic symptoms. All patients underwent angioplasty and stenting with dual antiplatelet therapy (DAPT). Data collected included demographics, comorbidities, stenosis characteristics, procedural details, and outcomes assessed by the modified Rankin Scale (mRS). Results: The median age was 63.5 years (IQR: 57–68.6), and 73.7% were male. Hypertension was the most common comorbidity (98%), followed by ischemic heart disease (58%) and diabetes mellitus (40.9%). Multi-location ICAS was significantly associated with patients over 75 years of age (p = 0.025). Additionally, obesity and stenosis severity greater than 70% showed trends toward significance, with p-values of 0.064 and 0.079, respectively. Stenosis predominantly affected the internal carotid artery (54.5%) and vertebrobasilar system (31.6%). The average hospital stay was longer for posterior circulation stenosis (7.1 days) compared to anterior circulation (4.7 days). The periprocedural complication rate was 0.7%, with two deaths attributed to ischemic complications. At follow-up, four patients experienced worsening mRS scores (>2), particularly those with severe stenosis in the basilar artery and M1 segment. Conclusions: ICAS in the Kazakh population is strongly associated with hypertension and aging, with posterior circulation stenosis contributing disproportionately to worse outcomes. The low complication rates highlight the safety of modern endovascular techniques. However, further research is needed to optimize treatment strategies for severe and multi-location ICAS, particularly in Central Asian populations.

An awake craniotomy's primary goal is to remove the tumor or damaged cells as much as possible without affecting the patient's capacity for clear thought or other crucial functions. This surgical procedure offers a better prognosis by balancing the maximum removal of lesions with the preservation of working zones. For patients with malignant gliomas, the current neurosurgical objective is for resection the large part of a tumor using contrast and not causing neurological deficits. Neurooncological patients are required to have further chemotherapy and radiotherapy, with a control MRI of the brain in 3 and 6 months. Real multidisciplinary work should be provided to improve each patient's quality of life and overall survival. This paper aims to report single case of successful awake craniotomy with fluorescence guidance and discuss the outcomes of the performed surgery.
