Abstract
Stroke-like symptoms are a common complaint in the emergency department; however, signs of an acute cerebrovascular event in a patient under the age of 50 can be both alarming and unexpected. In this case, a 41-year-old male presented to the emergency department with vague symptoms of intermittent weakness and paresthesias for 4 days. Originally deemed a "stroke code" in the field, the patient was immediately transferred to the computerized tomography scanner. The patient was later found to have a right-sided internal carotid dissection and subsequent right parietal lobe ischemic infarcts. This article highlights the need to maintain a high suspicion for acute cerebrovascular events, even in atypical presentations. The key features of caring for a patient experiencing carotid dissection, as well as their expected prognosis and care course, are also expounded upon. Early recognition of stroke-like symptoms in young, otherwise healthy, patients is critical to providing the needed care in a timely manner and to preserve future function and quality of life.

Efficacy of interventional closure therapy on cryptogenic stroke with coexisting patent foramen ovale in young patients and its impact on serum fibrinogen and D-dimer levels. Int J Neurosci 2023:1-8. [PMID: 38130242 DOI: 10.1080/00207454.2023.2298714] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Accepted: 12/19/2023] [Indexed: 12/23/2023]
Abstract
OBJECTIVE To explore the efficacy of interventional closure therapy in young patients with cryptogenic stroke and coexisting patent foramen ovale and analyze its impact on serum fibrinogen and D-dimer levels. METHODS All subjects in this study were young stroke patients with PFO. After excluding patients who did not meet the inclusion criteria, they were registered and divided into two groups based on the treatment method: the closure group and the medical group. RESULTS There were no significant differences in basic clinical data between the two groups, indicating comparability (p > 0.05). The closure group showed better heart function after treatment compared to the medical group, with significant differences (p < 0.05). Headache symptoms in the closure group were less severe than those in the medical group after treatment, with significant differences (p < 0.05). Laboratory indicators in the closure group were better than those in the medical group after treatment, with significant differences (p < 0.05). Serum fibrinogen and D-dimer levels in the closure group were lower than those in the medical group after treatment, with significant differences (p < 0.05). CONCLUSION Interventional closure therapy demonstrated positive effects on young patients with cryptogenic stroke and coexisting PFO, showing improvements in heart function, headache symptoms, and blood coagulation parameters. While the study suggests potential benefits, cautious interpretation is warranted, given the observational study design. Further research with a larger sample size and long-term follow-up is needed to validate these findings.

Abstract
BACKGROUND The incidence of ischemic stroke in young adults (18-45 years old) is increasing gradually. However, performing nutritional assessment in stroke patients is often challenging due to the lack of an accepted standard for nutritional assessment. METHODS Two hundred sixty young stroke patients were recruited in this study and 144 cases in the good prognosis group and 116 cases in the poor prognosis group were scored according to the modified Rankin scale 90 days after treatment. The National Institutes of Health Stroke Scale was performed on admission and discharge of patients. Serum interleukin 6 and high-sensitivity C-reactive protein were detected at patient presentation. The Prognostic Nutritional Index (PNI) was assessed on admission. Calculation formula of PNI score: serum albumin (g/L) + 5× total lymphocyte count (109/L). RESULTS The PNI at admission of young stroke patients with poor prognosis was higher than that of those with good prognosis. PNI at admission was significantly negatively correlated with National Institutes of Health Stroke Scale at discharge and modified Rankin scale score after 90 days in young stroke patients. PNI at admission was also significantly negatively correlated with serum levels of high-sensitivity C-reactive protein and interleukin -6 at admission. CONCLUSIONS PNI has a statistically predictive value for the 90-day prognosis of young stroke patients.

Abstract
INTRODUCTION COVID-19 has had innumerable impacts on the healthcare system, both by worsening patient illness and impeding effective and efficient care. Further, COVID-19 has been tied to increased rates of ischemic stroke, particularly among young patients. We utilized a national database to assess associations of COVID-19 with thrombectomy rates, mortality, and discharge disposition among stroke patients. METHODS Patients were identified from the National Inpatient Sample (NIS, 2020). Inclusion criteria selected for adult ischemic stroke patients; those with venous thrombosis or unspecified cerebral infarction were excluded. Patients were stratified by presence or absence of COVID-19 diagnosis. Outcome variables included mechanical thrombectomy, in-hospital mortality, and discharge disposition. Additional patient demographics, hospital characteristics, and disease severity metrics were collected. Statistical analysis was performed via multivariable logistic regression and log-binary regression. RESULTS 54,368 patients were included in the study; 2116 (3.89%) were diagnosed with COVID-19. COVID-19 was associated with lower rates of mechanical thrombectomy (OR 0.94, p < 0.0001), higher rates of in-hospital mortality (OR 1.14, p < 0.0001), and unfavorable discharge disposition (OR 1.08, p < 0.0001), even when controlling for illness severity. Other relationships, such as a male predominance among stroke patients with COVID-19, were also identified. CONCLUSION This study identified a relationship between COVID-19 diagnosis and worse outcomes for each metric assessed, including mechanical thrombectomy rates, in-hospital mortality, and discharge disposition. Several factors might underly this, ranging from systemic/multisystem inflammation and worsened disease severity to logistical barriers to treatment caused by COVID-19. Further research is needed to determine causality of these findings.

Quantitative and Qualitative Characteristics of Atherosclerotic Plaques on Carotid Arteries in Patients with Antiphospholipid Syndrome: The Role of MDCT Angiography. Diseases 2023; 11:131. [PMID: 37873775 PMCID: PMC10594423 DOI: 10.3390/diseases11040131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 09/23/2023] [Accepted: 09/24/2023] [Indexed: 10/25/2023] Open
Abstract
INTRODUCTION Antiphospholipid syndrome (APS) is an autoimmune disease characterised by arterious and venous thrombosis, miscarriage, and the presence of antiphospholipid antibodies (aPL) in the blood. As we know, APS is also characterised by accelerated atherosclerotic degeneration with an increased risk of thrombosis in all blood vessels, including the carotid arteries. Carotid artery stenosis can manifest in many different ways. The aim of this study is to present the results of our multidetector computerised tomography angiography (MDCTA) analysis of the carotid arteries in patients with primary and secondary APS compared with a control group. MATERIALS AND METHODS This study examined 50 patients with primary antiphospholipid syndrome (PAPS) and 50 patients with secondary antiphospholipid syndrome (SAPS). The results were compared with a control group also comprising 50 patients. The groups were analysed with respect to age, sex and the presence of well-established risk factors for vascular disease. The study was conducted using MDCTA, where we analysed the quantitative and qualitative (morphologic) characteristics of carotid artery lesions. RESULTS Patients from the control group had significantly elevated levels of cholesterol and triglycerides in comparison with patients with PAPS and SAPS (p < 0.001 and p < 0.05). The results show that carotid artery lesions were significantly more common in patients with APS (PAPS, n = 40, CI95: 0.50-0.75, p = 0.0322 and SAFS, n = 54, CI95: 0.59-0.80, p = 0.0004) than within the control group (n = 23). There was a statistically significant difference between patients with APS and the control group with respect to lesions in the distal segments (n = 27, CI95: 0.67-0.95, p = 0.0001), bulbi and proximal segments (n = 21, CI95: 0.84-1.00, p = 0.000005). The number of patients with one lesion (L) (n = 27) was significantly greater than the number of those with three (n = 10, CI95: 0.56-0.86, p = 0.0051) or four (n = 3, CI95: 0.73-0.98, p = 0.00001) lesions. There were also more patients with two lesions (n = 24) than those with four (n = 3) (CI95: 0.71-0.97, p = 0.00005). Carotid artery stenosis was shown as a percentage of the carotid artery lumen diameter (%DS). Stenosis of up to 30%, was more common in patients in the PAPS group (n = 12) than in the control group (n = 3) (CI95: 0.52-0.96, p = 0.0201), while the SAPS group (n = 17) had an even larger disparity (CI95: 0.62-0.97, p = 0.0017). We observed a highly significant difference in the frequency of stenoses between 30% and 50% DS between the PAPS group (n = 24) and the control group (n = 7) (CI95: 0.59-0.90, p = 0.0023), as well as the SAPS group (n = 30) (CI95: 0.65-0.92, p = 0.0002). A qualitative analysis of plaque morphology revealed that patients with PAPS had significantly more soft tissue lesions (n = 23) compared with calcified lesions (n = 2) (CI95: 0.74-0.99, p = 0.00003), as well as more mixed plaques (n = 9) and calcified plaques (n = 2) (CI95: 0.48-0.98, p = 0.0348). Patients within the SAPS group had significantly more soft tissue (n = 35) than calcified lesions (n = 3) (CI95: 0.79-0.98, p = 0.00000021), as well as more mixed lesions (n = 21) compared with calcified (n = 3) (CI95: 0.68-0.97, p = 0.0002). CONCLUSIONS Our study shows that subclinical manifestations of carotid artery lesions were more common in patients with APS. We came to the conclusion that MDCTA is an accurate diagnostic method because it is a safe method that provides us with a great quantity of accurate information about the characteristics of atheromatous plaques, which aids us in the further planning of treatment for patients with APS.

Abstract
Our previous study showed l-borneol reduced cerebral infarction in the acute stage after cerebral ischemia, but there is little about the study of subacute phase. We herein investigated the cerebral protective effects of l-borneol on neurovascular units (NVU) in the subacute phase after transient middle cerebral artery occlusion (t-MCAO). The t-MCAO model was prepared by the line embolus method. Zea Longa, mNss, HE, and TTC staining were used to evaluate the effect of l-borneol. We evaluated the mechanisms of l-borneol on inflammation, p38 MAPK pathway, and apoptosis, etc. through various technologies. l-borneol 0.2, 0.1, 0.05 g·kg-1 could significantly reduce cerebral infarction rate, alleviate the pathological injury, and inhibit inflammation reaction. l-borneol could also significantly increase brain blood supply, Nissl bodies, and the expression of GFAP. Additionally, l-borneol activated the p38 MAPK signaling pathway, inhibited cell apoptosis, and maintained BBB integrity. l-borneol had a neuroprotective effect, which was related to activating the p38 MAPK signaling pathway, inhibiting inflammatory response and apoptosis, and improving cerebral blood supply to protect BBB and stabilize and remodel NVU. The study will provide a reference for the use of l-borneol in the treatment of ischemic stroke in the subacute phase.

Abstract
BACKGROUND Cases of multiple cerebral aneurysms are rare. In this case report, we describe a male patient with multiple, enlarging, and ruptured aneurysms. The two aneurysms were believed to be dissecting aneurysms. CASE DESCRIPTION A 47-year-old man presented with left limb paralysis. Magnetic resonance imaging revealed a cerebral infarction. Digital subtraction angiography (DSA) identified an aneurysm and occlusion in the right middle cerebral artery (MCA). The MCA aneurysm was remarkably enlarged on the eighth day after cerebral ischemia and was treated using endovascular techniques. Two weeks after the endovascular treatment, the patient experienced a severe headache and became comatose, and a subarachnoid re-hemorrhage was confirmed. The fourth DSA revealed an enlarging dissecting aneurysm in the posterior cerebral artery. The patient died without further treatment. CONCLUSION Some dissecting aneurysms rapidly enlarge and rupture.

Block Copolymer Nanomicelle-Encapsulated Curcumin Attenuates Cerebral Ischemia Injury and Affects Stem Cell Marker Expression by Inhibiting lncRNA GAS5. Stem Cells Int 2023; 2023:9821500. [PMID: 36845969 PMCID: PMC9957624 DOI: 10.1155/2023/9821500] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 10/11/2022] [Accepted: 01/25/2023] [Indexed: 02/19/2023] Open
Abstract
Stroke has become the most common cause of death among residents in China, among which ischemic stroke accounts for the vast majority reaching 70% to 80%. It is of great importance to actively investigate the protective mechanism of cerebral ischemia injury after IS (ischemic stroke). We constructed cerebral ischemia injury models in vivo MACO rat and in vitro (oxygen-glucose deprivation cell model) and set up different interference groups. RT-PCR (reverse transcription PCR) was conducted to detect the expression of lncRNA in neuronal cells, brain tissue, and plasma of different groups, and ELISA (enzyme-linked immunosorbent assay) and western blot were used to detect the expression of the protein in neuronal cells, brain tissue, and plasma of different groups. Cell activity was detected by the CCK-8 assay, while cell apoptosis was examined by TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labeling) assay. In the rats' neuronal cells and brain tissue, curcumin can inhibit the expression of lncRNA GAS5 (long noncoding RNA growth arrest-specific 5). In oxygen-glucose-deprived neuronal cells in vitro, curcumin and low-expressed lncRNA GAS5 can enhance cell activity and decline cell apoptosis, but the addition of curcumin and overexpressed lncRNA GAS5 can make this phenomenon disappear. In neuronal cells, plasma, and brain tissue, curcumin and the low-expressed lncRNA GAS5 can inhibit the expression of IL-1β (interleukin 1 beta), TNF-α (tumor necrosis factor alpha), IL-6 (interleukin 6), Sox2 (SRY-box transcription factor 2), Nanog, and Oct4 (octamer-binding transcription factor 4). However, overexpressed lncRNA GAS5 and curcumin made the inhibitory effect disappear. In conclusion, this study demonstrated that curcumin could inhibit the expression of lncRNA GAS5, thereby inhibiting the expression of inflammation-related factors IL-1β, TNF-α, and IL-6, and ultimately achieve the purpose of attenuating cerebral ischemic cell damage. However, curcumin and lncRNA GAS5 may not alleviate cerebral ischemic cell damage by affecting stem cell differentiation.

Abstract
INTRODUCTION Different mechanisms may underlie cryptogenic stroke, including subclinical atrial fibrillation (AF), nonstenotic carotid plaques (NCP), and aortic arch atherosclerosis (AAA). In a cohort of cryptogenic stroke patients, we aimed to: (1) evaluate the prevalence of subclinical AF, NCP, and AAA, and reclassify the etiology accordingly; (2) compare the clinical features of patients with reclassified etiology with those with confirmed cryptogenic stroke. METHODS Data of patients hospitalized for cryptogenic stroke between January 2018 and February 2021 were retrospectively analyzed. Patients were included if they received implantable cardiac monitoring (ICM) to detect subclinical AF. Baseline computed tomography angiography (CTA) was re-evaluated to assess NCP and AAA. Since aortic plaques with ulceration/intraluminal thrombus were considered pathogenetic during the initial workup, only patients with milder AAA were included. Stroke etiology was reclassified as "cardioembolic", "atherosclerotic", or "mixed" based on the detection of AF and NCP/AAA. Patients with "true cryptogenic" stroke (no AF, ipsilateral NCP, or AAA detected) were compared with those with reclassified etiology. RESULTS Among 63 patients included, 21 (33%) were diagnosed with AF (median follow-up time of 15 months), 12 (19%) had ipsilateral NCP, and 6 (10%) had AAA. Stroke etiology was reclassified in 30 patients (48%): cardioembolic in 14 (22%), atherosclerotic in 9 (14%), and mixed in 7 (11%). Patients with true cryptogenic stroke were younger compared to those with reclassified etiology (p = 0.001). DISCUSSION One or more potential covert stroke sources can be recognized in half of the patients with a cryptogenic stroke through long-term cardiac monitoring and focused CTA re-assessment.

Antithrombotic and antiplatelet effects of plant-derived compounds: a great utility potential for primary, secondary, and tertiary care in the framework of 3P medicine. EPMA J 2022; 13:407-431.

Abstract
Thromboembolism is the third leading vascular disease, with a high annual incidence of 1 to 2 cases per 1000 individuals within the general population. The broader term venous thromboembolism generally refers to deep vein thrombosis, pulmonary embolism, and/or a combination of both. Therefore, thromboembolism can affect both – the central and peripheral veins. Arterial thromboembolism causes systemic ischemia by disturbing blood flow and oxygen supply to organs, tissues, and cells causing, therefore, apoptosis and/or necrosis in the affected tissues. Currently applied antithrombotic drugs used, e.g. to protect affected individuals against ischemic stroke, demonstrate significant limitations. For example, platelet inhibitors possess only moderate efficacy. On the other hand, thrombolytics and anticoagulants significantly increase hemorrhage. Contextually, new approaches are extensively under consideration to develop next-generation antithrombotics with improved efficacy and more personalized and targeted application. To this end, phytochemicals show potent antithrombotic efficacy demonstrated in numerous in vitro, ex vivo, and in vivo models as well as in clinical evaluations conducted on healthy individuals and persons at high risk of thrombotic events, such as pregnant women (primary care), cancer, and COVID-19-affected patients (secondary and tertiary care). Here, we hypothesized that specific antithrombotic and antiplatelet effects of plant-derived compounds might be of great clinical utility in primary, secondary, and tertiary care. To increase the efficacy, precise patient stratification based on predictive diagnostics is essential for targeted protection and treatments tailored to the person in the framework of 3P medicine. Contextually, this paper aims at critical review toward the involvement of specific classes of phytochemicals in antiplatelet and anticoagulation adapted to clinical needs. The paper exemplifies selected plant-derived drugs, plant extracts, and whole plant foods/herbs demonstrating their specific antithrombotic, antiplatelet, and fibrinolytic activities relevant for primary, secondary, and tertiary care. One of the examples considered is antithrombotic and antiplatelet protection specifically relevant for COVID-19-affected patient groups.
