Abstract
Introduction Transient ischemic attacks (TIAs) are brief episodes of neurological impairment caused by reduced blood flow to the brain, spinal cord, or retina, typically lasting under an hour. Recent advances in neuroimaging suggest that some TIAs may actually be small strokes with resolved symptoms. This study focuses on assessing the knowledge and management of TIAs among primary care physicians and nurses in Al-Ahsa, Saudi Arabia. Methodology This is a cross-sectional study, conducted in Al-Ahsa, Saudi Arabia, during the period July to August 2023. Data were collected using an electronic questionnaire and was analyzed using IBM SPSS Statistics for Windows, version 27.0.1 (released 2020, IBM Corp., Armonk, New York, United States). Results Among the participants, 64.0% correctly identified TIA as an ischemic neurological deficit. However, only 20.2% provided correct responses for all TIA symptoms. Regarding diagnostic tests, 47.4% acknowledged the need for neuroimaging immediately after TIA, while 17.5% recognized the importance of ultrasonography of the supra-aortic trunks. In terms of TIA management, 38.6% preferred referral to the emergency service, and 41.2% correctly perceived the risk of TIA recurrence as similar to that of established cerebral ischemic stroke. Significant disparities were observed in the recognition of TIA symptoms, with physicians outperforming nurses, particularly in identifying motor deficits (82.4% vs. 65.2%) and speech alterations (86.8% vs. 76.1%, p = 0.004). However, nurses exhibited better knowledge in recognizing the need for a neuroimaging test (48.5% vs. 45.7%, p = 0.849) and the urgency of conducting a transcranial Doppler (TCD) (19.1% vs. 23.9%, p = 0.641). Conclusion A considerable proportion of healthcare providers demonstrate a good understanding of TIA definition and management. However, the lack of significant predictors for good knowledge and attitude suggests the need for more comprehensive strategies to enhance TIA management expertise across healthcare professionals.

Brain Sci 2023; 13:brainsci13050840. [PMID: 37239312 DOI: 10.3390/brainsci13050840] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 05/10/2023] [Accepted: 05/18/2023] [Indexed: 05/28/2023] Open
Abstract
Background: The standard reperfusion therapy for acute ischemic stroke (AIS) is considered to be thrombolysis, but its application is limited by the high risk of hemorrhagic transformation (HT). This study aimed to analyze risk factors and predictors of early HT after reperfusion therapy (intravenous thrombolysis or mechanical thrombectomy). Material and methods: Patients with acute ischemic stroke who developed HT in the first 24 h after receiving rtPA thrombolysis or performing mechanical thrombectomy were retrospectively reviewed. They were divided into two groups, respectively, the early-HT group and the without-early-HT group based on cranial computed tomography performed at 24 h, regardless of the type of hemorrhagic transformation. Results: A total of 211 consecutive patients were enrolled in this study. Among these patients, 20.37% (n = 43; age: median 70.00 years; 51.2% males) had early HT. Multivariate analysis of independent risk factors associated with early HT found that male gender increased the risk by 2.7-fold, the presence of baseline high blood pressure by 2.4-fold, and high glycemic values by 1.2-fold. Higher values of NIHSS at 24 h increased the risk of hemorrhagic transformation by 1.18-fold, while higher values of ASPECTS at 24 h decreased the risk of hemorrhagic transformation by 0.6-fold. Conclusions: In our study, male gender, baseline high blood pressure, and high glycemic values, along with higher values of NIHSS were associated with the increased risk of early HT. Furthermore, the identification of early-HT predictors is critical in patients with AIS for the clinical outcome after reperfusion therapy. Predictive models to be used in the future to select more careful patients with a low risk of early HT need to be developed in order to minimize the impact of HT associated with reperfusion techniques.

A Review of Risk Factors and Predictors for Hemorrhagic Transformation in Patients with Acute Ischemic Stroke. Int J Vasc Med 2021; 2021:4244267. [PMID: 34912581 PMCID: PMC8668348 DOI: 10.1155/2021/4244267] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 11/15/2021] [Accepted: 11/17/2021] [Indexed: 12/26/2022] Open
Abstract
Acute ischemic strokes (AIS) and hemorrhagic strokes lead to disabling neuropsychiatric and cognitive deficits. A serious and fatal complication of AIS is the occurrence of hemorrhagic transformation (HT). HT is cerebral bleeding that occurs after an ischemic event in the infarcted areas. This review summarises how specific risk factors such as demographic factors like age, gender, and race/ethnicity, comorbidities including essential hypertension, atrial fibrillation, diabetes mellitus, congestive heart failure, and ischemic heart disease along with predictors like higher NIHSS score, larger infarction size, cardioembolic strokes, systolic blood pressure/pulse pressure variability, higher plasma glucose levels, and higher body temperature during ischemic event, lower low-density lipoprotein and total cholesterol, early ischemic changes on imaging modalities, and some rare causes make an individual more susceptible to developing HT. We also discuss few other risk factors such as the role of blood-brain barrier, increased arterial stiffness, and globulin levels in patients postreperfusion using thrombolysis and mechanical thrombectomy. In addition, we discuss the implications of dual antiplatelet therapy and the length of treatment in reference to the incidence of developing HT. Current research into inflammatory mediators and biomarkers such as Cyclooxygenase-2, matrix metalloproteinases, and soluble ST2 and their potential role as treatment options for HT is also briefly discussed. Finally, this review calls for more research into use of dual antiplatelet and the timing of antiplatelet and anticoagulant use in reference to hemorrhagic transformation.

Abstract
BACKGROUND AND PURPOSE Little is known about the long-term association between transient ischaemic attack (TIA) and stroke. Therefore, the goal of this study was to analyze the long-term risk of stroke and associated predictors in a large cohort of TIA patients followed in general practices in Germany. METHODS This study included patients with an initial TIA diagnosis and subsequently followed up in one of 1262 general practices in Germany between January 2007 and December 2016 (N = 19 824 patients). The primary outcome of the study was the risk of ischaemic stroke within 10 years of the initial diagnosis of TIA. The secondary outcome was the identification of demographic, clinical and pharmaceutical variables significantly associated with stroke in TIA patients. RESULTS Within 10 years of the initial TIA diagnosis, 18.3% of individuals were diagnosed with stroke. Age was positively associated with stroke, with hazard ratios ranging from 1.88 in patients aged 51-60 years to 4.00 in those aged >80 years (reference group: patients aged ≤50 years). Furthermore, male sex, hypertension, diabetes mellitus, atrial fibrillation and ischaemic heart diseases had an additional impact on the risk of stroke. Finally, new oral anticoagulants, heparins, diuretics, angiotensin II receptor blockers and platelet aggregation inhibitors were identified as protective factors. CONCLUSIONS In a cohort of almost 20 000 TIA patients, 18.3% were diagnosed with stroke within 10 years after the TIA index event. Several demographic, clinical and pharmaceutical variables significantly predicted the long-term risk of stroke in TIA patients.

Abstract
PURPOSE OF REVIEW To review recent advances in the management of acute ocular ischemic events, including: transient monocular vision loss, central and branch retinal artery occlusions, and nonarteritic anterior ischemic optic neuropathy. RECENT FINDINGS Transient monocular vision loss and acute retinal arterial occlusions require immediate diagnosis and management, with recognition of these events as transient ischemic attack or stroke equivalents, respectively. Patients should undergo an immediate stroke workup in a stroke center, similar to patients with acute cerebral ischemia. The treatment of central retinal artery occlusions remains limited despite the growing use of thrombolytic treatments. The indication for these treatments remains under debate. No quality evidence exists to support any therapy, including corticosteroids, in the treatment of nonarteritic anterior ischemic optic neuropathy. The highest priority in management is to rule-out giant cell arteritis. SUMMARY Effective therapies for the treatment of ischemic events of the retina and optic nerve remain elusive. Clinicians should focus on the prompt recognition of these events as ocular emergencies and immediately refer patients with vascular transient visual loss and acute central and branch retinal arterial occlusions to the nearest stroke center.

Abstract
Acute retinal arterial ischemia, including vascular transient monocular vision loss (TMVL) and branch (BRAO) and central retinal arterial occlusions (CRAO), are ocular and systemic emergencies requiring immediate diagnosis and treatment. Guidelines recommend the combination of urgent brain magnetic resonance imaging with diffusion-weighted imaging, vascular imaging, and clinical assessment to identify TMVL, BRAO, and CRAO patients at highest risk for recurrent stroke, facilitating early preventive treatments to reduce the risk of subsequent stroke and cardiovascular events. Because the risk of stroke is maximum within the first few days after the onset of visual loss, prompt diagnosis and triage are mandatory. Eye care professionals must make a rapid and accurate diagnosis and recognize the need for timely expert intervention by immediately referring patients with acute retinal arterial ischemia to specialized stroke centers without attempting to perform any further testing themselves. The development of local networks prompting collaboration among optometrists, ophthalmologists, and stroke neurologists should facilitate such evaluations, whether in a rapid-access transient ischemic attack clinic, in an emergency department-observation unit, or with hospitalization, depending on local resources.
