Decompressive surgery in cerebral venous sinus thrombosis due to vaccine-induced immune thrombotic thrombocytopenia.

BACKGROUND AND PURPOSE: Cerebral venous sinus thrombosis due to vaccine-induced immune thrombotic thrombocytopenia (CVST-VITT) is an adverse drug reaction occurring after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. CVST-VITT patients often present with large intracerebral haemorrhages and a high proportion undergoes decompressive surgery. Clinical characteristics, therapeutic management and outcomes of CVST-VITT patients who underwent decompressive surgery are described and predictors of in-hospital mortality in these patients are explored. METHODS: Data from an ongoing international registry of patients who developed CVST within 28 days of SARS-CoV-2 vaccination, reported between 29 March 2021 and 10 May 2022, were used. Definite, probable and possible VITT cases, as defined by Pavord et al. (N Engl J Med 2021; 385: 1680-1689), were included. RESULTS: Decompressive surgery was performed in 34/128 (27%) patients with CVST-VITT. In-hospital mortality was 22/34 (65%) in the surgical and 27/94 (29%) in the non-surgical group (p < 0.001). In all surgical cases, the cause of death was brain herniation. The highest mortality rates were found amongst patients with preoperative coma (17/18, 94% vs. 4/14, 29% in the non-comatose; p < 0.001) and bilaterally absent pupillary reflexes (7/7, 100% vs. 6/9, 67% with unilaterally reactive pupil, and 4/11, 36% with bilaterally reactive pupils; p = 0.023). Postoperative imaging revealed worsening of index haemorrhagic lesion in 19 (70%) patients and new haemorrhagic lesions in 16 (59%) patients. At a median follow-up of 6 months, 8/10 of surgical CVST-VITT who survived admission were functionally independent. CONCLUSIONS: Almost two-thirds of surgical CVST-VITT patients died during hospital admission. Preoperative coma and bilateral absence of pupillary responses were associated with higher mortality rates. Survivors often achieved functional independence.

Association of monocyte/high-density lipoprotein cholesterol ratio and the carotid intima-media thickness in diabetic patients.

OBJECTIVES: The goal of this study was to see whether there was a link between the monocyte/high-density lipoprotein cholesterol ratio (MHR) and carotid intima-media thickness (CIMT) in people with type 2 diabetes. METHODS: Duplex ultrasonography parameters and demographic, physical, and paraclinical assessments were recorded. Using the t-test, the MHR and CIMT were compared between the two groups. Regression models were also constructed. RESULTS: A total of 118 diabetics and 126 non-diabetics were included in the cross-sectional research. According to the stated diabetes duration, the observed age difference of 7 years might be considered. The MHR and CIMT were not substantially different between the two groups. In the DM and non-DM groups, the Spearman correlations between MHR and CIMT were 0.32 and - 0.08, respectively (p-values = 0.001 and 0.379). Thus, regression models (stratified for DM/non-DM and male/female) revealed that the MHR is a significant predictor of CIMT, but only in the case of male DM individuals, when crudely adjusted for confounders. CONCLUSIONS: In diabetes mellitus, the current investigation found a direct link between MHR and CIMT. In addition, in male diabetic subjects, MHR was demonstrated to be a predictor of CIMT.

Spontaneous Intracerebral Hemorrhage (ICH) associated with pregnancy and SARS-CoV-2 infection: a case report.

BACKGROUND: Coronavirus Disease 2019 (COVID-19) is predominately known as a respiratory disease associated with pneumonia, acute respiratory distress syndrome and multiorgan failure. However, extra-pulmonary complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are increasingly being recognized. In this regard, some studies implied the hemostatic and vascular involvements in patients with SARS-CoV-2 infection. CASE PRESENTATION: We describe a case of spontaneous Intracerebral Hemorrhage (ICH) in a pregnant patient with COVID-19 and history of cesarean section a week before the occurrence of ICH. The patient underwent emergent craniotomy with acceptable outcome. Hemorrhagic events, including ICH, may happen during COVID-19 infection with several possible mechanisms. CONCLUSION: COVID-19 patients, especially high-risk groups, are at a risk of intracranial hemorrhage. Therefore, close follow-up must be maintained and hemorrhagic events must be kept in mind in these cases.

An assessment on the use of infra-scanner for the diagnosis of the brain hematoma in head trauma.

PURPOSE: Timely identification and treatment of intracranial hematomas in patients with brain injury is essential for successful treatment. This study evaluates Infra-scanner as a handy medical screening tool for diagnosing, on-site, cerebral hematomas in patients with head injury. MATERIALS AND METHODS: Patients referred to the emergency department of university hospitals with mild to moderate brain trauma, up to 12 h from injury were included. NIR sensors of infra-scan device were placed on the right and left frontal, temporal, peritoneal and occipital parts of the head and light absorption was recorded. Positive or negative cerebral hemorrhage cases were compared with contrast-enhanced CT scan results as the gold standard. Diagnostic parameters of the device and cases related to bleeding were analyzed and reported. RESULTS: A total of 300 patients were studied. Sensitivity of the infrasound scanner in the Iranian study population was 94.8 (95% CI: 88% -100) and its specificity was 86.9 (95% CI: 79% -99% 99). Negative predictive value (NPV) was 90.3% and positive predictive value (PPV) was 92.9%. Sensitivity in men (95.7%) (95%CI, 90% -1) was more than women (95% CI, 81% -99%)90%. At the ages of less than 36 years, sensitivity (95.3%) and specificity (87.1%) were more than sensitivity (94.4%) and specificity (86.5%) over 36 years old. If the test had been performed in less than / equal to two hours from trauma, the sensitivity (94.9%) and the specificity (92%) were greater than the sensitivity (94.6%) and the specificity (75%) during when the scan had been performed in more than two hours from trauma. In general, in extra-axial bleeding including EDH, SAH, SDH, the sensitivity was 95.1% and the specificity was 84.5%, while in intra-axial bleeding, including ICH and IVH, the sensitivity was lower (93.9%) and the specificity was 91.7. The sensitivity of the device in detecting bleeding in the occipital lobe (95.8%) was higher than other brain lobes. CONCLUSION: This study shows that Infra-scanner is useful in initial examination and screening of patients with head injury and can be used as an adjunct to a CT scan or when not available and may allow earlier treatment which reduce the secondary damage to the hematoma.

Rivaroxaban for the treatment of cerebral venous thrombosis.

BACKGROUND: New Oral Anticoagulants (NOACs) such as Rivaroxaban are introduced as alternatives to conventional vitamin-K antagonists in the long-term treatment of thrombotic events due to their lower bleeding risk. There is a lack of evidence on the effectiveness and safety of Rivaroxaban in Cerebral venous thrombosis (CVT). This study aims to assess the effectiveness and bleeding risk of Rivaroxaban in comparison with Warfarin for the treatment of CVT. MATERIALS AND METHODS: 36 patients with diagnosis of CVT were included. Clinical and background information was assessed on admission and patients were followed for at least 12 months. Measured outcomes were modified Rankin Scale (mRS), evidence of recanalization on contrast-enhanced Brain MR venography (MRV) and major or minor bleeding. Patients were divided into two groups according to the type of oral anticoagulant (Rivaroxaban vs Warfarin). Groups were compared in terms of final outcomes and side effects. RESULT: Overall, 13 (36.11%) patients received Warfarin and 23 (63.89%) received Rivaroxaban. Optimal mRS score (0-1) was attained in 9 of 10 (90%) of patients treated with Rivaroxaban and 19 of 22 (86.36%) of patients received Warfarin. MRV showed complete or partial recanalization in 12 of 14 (85.71%) patients treated with Rivaroxaban and all patients in the Warfarin group. There was no significant difference between the two groups in terms of major and minor hemorrhage. CONCLUSION: Rivaroxaban holds promise for the treatment of CVT.

Rituximab and risk of COVID-19 infection and its severity in patients with MS and NMOSD.

BACKGROUND: Choosing a safe disease modifying therapy during the COVID-19 pandemic is challenging. This case series study was conducted to determine the incidence rate and the course of Covid-19 infection in MS/NMOSD patients treated with Rituximab. METHODS: In this study, we designed a web-based questionnaire. Baseline information such as patient- reported walking disability, total number of Rituximab infusions received, delayed injections, occurrence of any relapse, and the use of corticosteroids during the pandemic were collected. Also, information regarding the Covid-19 pandemic such as adherence to self-isolation, any recent exposure to an infected individual and the presence of suggestive symptoms were collected. In case of positive test results, patients were grouped into 2 categories; mild to moderate and seriously ill and outcomes were evaluated as favorable (improved/ discharged) and unfavorable (expired). RESULTS: Two hundred fifty-eight patients with Multiple Sclerosis were enrolled in this study, 9 of the subjects (3.4%) were confirmed positive for Covid-19, five of which required hospitalizations (55.5%), two patients required ICU admission (22.2%) and 2 two patients died (22.2%). None of these patients ever mentioned using corticosteroids during the pandemic. In comparison to MS patients who were not receiving disease modifying therapy (DMT), our study indicated a higher incidence of Covid-19 infection, higher ratio of serious illness and a higher fatality ratio. CONCLUSIONS: Rituximab seems not to be safe enough during the pandemic.

Toll-Like Receptor Signaling Pathways: Novel Therapeutic Targets for Cerebrovascular Disorders.

Toll-like receptors (TLRs), a class of pattern recognition proteins, play an integral role in the modulation of systemic inflammatory responses. Cerebrovascular diseases (CVDs) are a group of pathological conditions that temporarily or permanently affect the brain tissue mostly via the decrease of oxygen and glucose supply. TLRs have a critical role in the activation of inflammatory cascades following hypoxic-ischemic events and subsequently contribute to neuroprotective or detrimental effects of CVD-induced neuroinflammation. The TLR signaling pathway and downstream cascades trigger immune responses via the production and release of various inflammatory mediators. The present review describes the modulatory role of the TLR signaling pathway in the inflammatory responses developed following various CVDs and discusses the potential benefits of the modulation of different TLRs in the improvement of functional outcomes after brain ischemia.

Relationship between serum levels of folic acid and homocysteine with cognitive impairment in patients diagnosed with multiple sclerosis.

Multiple Sclerosis (MS), one of the most common neurological diseases, plays a major role in the ailments of adults. Studies on the role of homocysteine (Hcy) and folic acid in causing cognitive disorders in patients diagnosed with MS are still ongoing. This study aimed to evaluate the serum levels of folic acid and Hcy related to cognitive impairment in patients with multiple sclerosis. This prospective clinical study was conducted on 57 patients diagnosed with MS who were referred to Firoozgar Hospital, Tehran, Iran (Between November 2019 and September 2021). Demographic information and clinical characteristics of enrolled patients were recorded in a predesigned checklist. These characteristics were comprised of outcomes related to the Brief International Cognitive Assessment for MS, and the patient's Hcy and acid folic levels. Data were analyzed using SPSS version 25. Out of 57 enrolled patients, 39 subjects (68.4%) were female and 18 subjects (31.6%) were male, with a mean age of 36.87 ±â€…9.40 years old. In terms of disease time span, there was a mean duration of 3.80 ±â€…4.94 years (range: 1-23 years). There were no significant differences between the mean score of Brief International Cognitive Assessment for MS scale with patient's sex (P value: .88), and disease duration of patients (P value: .86). There was no significant relationship between the serum levels of acid folic and Hcy with cognitive impairment (P value > .05). The study results revealed that there were no significant relationships between the folic acid, Hcy levels, disease duration, and the type of MS disease with the severity of cognitive impairment. More randomized controlled clinical trials are needed to confirm the relationships between the folic acid and Hcy levels with cognitive impairment in patients with MS.

Evaluation of carotid Intima-Media Thickness (IMT) in amyotrophic lateral sclerosis disease using ultrasonography.

BACKGROUND: Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease with multi-mechanisms as; inflammation, oxidative stress, glutamate excitotoxicity, protein aggregation, etc. This study aimed to evaluate the carotid Intima-Media Thickness (IMT) in ALS and healthy groups, as a possible indicator of these mechanisms. METHODS: 42 patients with ALS along with 53 normal age and body mass index (BMI) matched participants were recruited from the Firoozgar hospital. Carotid IMT values of the participants were measured using B-mode ultrasonography. Using Pearson correlation and logistic regression adjusting with age, BMI, and gender, the IMT values were assessed. RESULTS: The mean right and left carotid IMT values of the ALS patients (0.66 ± 0.09) were significantly higher than normal participants (0.45 ± 0.10) (p < 0.001). In addition, the IMT values were highly correlated with the age (r = 0.632; p < 0.001) and the age of ALS onset (r = 0.595; p < 0.001), in contrast to the BMI. Moreover, the higher value of IMT was associated with an increasing risk of ALS with an odd ratio (OR) of 1.483 (95 % Confidence interval [1.026-2.144]). Eventually, evaluating IMT by classifying ALS patients based on the ALS Health State Scale (ALSHSS) from early to late stage revealed a non-linear increase in the OR (1.372, 1.898, 2.172, and 3.403). CONCLUSION: The increased value of the carotid IMT independent of BMI in ALS could be assessed through ultrasonography as a convenient tool to evaluate the disease severity or possible systemic inflammation.

Global prevalence and incidence of Young Onset Parkinson's disease: A systematic review and meta-analysis.

BACKGROUND: There is a lack of enough evidence regarding the epidemiology of Young-onset Parkinson's disease (YOPD) which is needed by clinicians and healthcare policymakers. AIM: Herein, in this systematic review and meta-analysis, we aimed to estimate the global prevalence and incidence rates of YOPD. METHODS: We searched the literature in PubMed, Scopus, and Web of Science in May 2022. We included retrospective, prospective, cross-sectional observational population-based studies that reported the prevalence or incidence of PD in individuals younger than 40 years with known diagnostic criteria. RESULTS: After two-step screening, 50 studies were eligible to be included in our study. The age-standardized prevalence of YOPD was 10.2 per 100,000 persons globally while it was 14.7 per 100,000 population in European countries. Age-standardized prevalence estimates for 5-year age bands showed that the YOPD prevalence estimates varied from 6.1 per 100,000 population in the group aged 20-24 to 16.1 per 100,000 population in the group aged 35-39. Also, the age-standardized incidence of YOPD was 1.3 per 100,000 person-years population worldwide and 1.2 per 100,000 person-years in the European population. CONCLUSION: Based on this systematic review and meta-analysis, the overall prevalence of YOPD is 10.2 per 100,000 population, although estimates of the prevalence and incidence in low-income countries remain scarce. To improve monitoring and certain diagnoses of YOPD, healthcare providers and policymakers should be aware that much more effective tools are required.

Predicting the conversion from clinically isolated syndrome to multiple sclerosis: An explainable machine learning approach.

INTRODUCTION: Predicting the conversion of clinically isolated syndrome (CIS) to clinically definite multiple sclerosis (CDMS) is critical to personalizing treatment planning and benefits for patients. The aim of this study is to develop an explainable machine learning (ML) model for predicting this conversion based on demographic, clinical, and imaging data. METHOD: The ML model, Extreme Gradient Boosting (XGBoost), was employed on the public dataset of 273 Mexican mestizo CIS patients with 10-year follow-up. The data was divided into a training set for cross-validation and feature selection, and a holdout test set for final testing. Feature importance was determined using the SHapley Additive Explanations library (SHAP). Then, two experiments were conducted to optimize the model's performance by selectively adding variables and selecting the most contributive variables for the final model. RESULTS: Nine variables including age, gender, schooling, motor symptoms, infratentorial and periventricular lesion at imaging, oligoclonal band in cerebrospinal fluid, lesion and symptoms types were significant. The model achieved an accuracy of 83.6 %, AUC of 91.8 %, sensitivity of 83.9 %, and specificity of 83.4 % in cross-validation. In the final testing, the model achieved an accuracy of 78.3 %, AUC of 85.8 %, sensitivity of 75 %, and specificity of 81.1 %. Finally, a web-based demo of the model was created for testing purposes. CONCLUSION: The model, focusing on feature selection and interpretability, effectively stratifies risk for treatment decisions and disability prevention in MS patients. It provides a numerical risk estimate for CDMS conversion, enhancing transparency in clinical decision-making and aiding in patient care.

Optimizing Acute Ischemic Stroke Outcomes: The Role of Tenecteplase Before Mechanical Thrombectomy.

PURPOSE: Acute ischemic stroke (AIS) is a life-threatening condition demanding prompt reperfusion to salvage brain tissue. Thrombolytic drugs, like tenecteplase (TNK), offer clot dissolution, but time constraints and contraindications limit their use. Mechanical thrombectomy (MT) revolutionized AIS treatment, especially for large vessel occlusions (LVO). Recent evidence suggests that administering TNK before MT improves recanalization and outcomes, challenging the dominance of alteplase. METHODS: Relevant articles focusing on TNK before MT were retrieved from PubMed, Scopus, and Web of Science, looking for randomized controlled trials (RCT), clinical trials, and meta-analyses in humans until 2024. FINDINGS: TNK, a genetically engineered thrombolytic, exhibits superior fibrin specificity and a longer half-life than alteplase. Clinical trials comparing TNK and alteplase before MT showcase enhanced recanalization, functional outcomes, and safety with TNK. Advanced neuroimaging aids patient selection, though its cost-effectiveness warrants consideration. Dosing studies favor a 0.25 mg/kg dose for efficacy and reduced complications. Clinical guidelines from various associations acknowledge TNK's potential as an alteplase alternative for AIS treatment, particularly for LVOs eligible for thrombectomy. IMPLICATIONS: In conclusion, TNK emerges as a promising option for bridging therapy in AIS, displaying efficacy and safety benefits, especially when administered before MT. Its fibrin specificity, longer half-life, and potential for improved outcomes position TNK as a viable alternative to alteplase, potentially transforming the landscape of AIS treatment strategies. While limitations like small sample sizes and variations in protocols exist, future research should focus on large-scale RCT, subgroup analyses, and cost-effectiveness evaluations to further elucidate TNK's role in optimizing AIS management.

Transradial access for neurointerventional procedures: A practical approach.

INTRODUCTION: Transradial approach (TRA) is a new technique proposed for performing cerebral angiography and neuro-interventional procedures. In this article, we sought to provide a step-by-step guide for carrying out a diagnostic cerebral angiography using this approach and summarize our center's experience. MATERIAL AND METHODS: Records of patients since January 2020 were investigated, and data on demographic indices, reports of the procedures, outcomes, and complications were extracted. Then, these data were used to develop a step-by-step instruction for TRA cerebral angiography. RESULTS: Two hundred eighty-nine patients matched our eligibility criteria with a mean age of 50 years and a female-to-male ratio of 1.18. Overall, TRA was carried out successfully for 97.2% (281 patients). In case TRA failed, transfemoral approach was considered for the procedure. Three minor complications (two vasospasm and one small hematoma) and two major complications (one pseudoaneurysm of the radial artery and one radial artery avulsion) were observed. CONCLUSION: This article covers challenges a neurointerventionalist may face during a diagnostic cerebral angiography using TRA. Furthermore, our findings indicated that cerebral angiography with TRA might be performed safely and with a great success rate.

Status epilepticus and the presence of SARS-COV-2 in the cerebrospinal fluid: A case report.

A growing number of studies indicate a broad range of neurological manifestations, including seizures, occur in patients with COVID-19 infection. We report a 29-year-old female patient with status epilepticus and positive SARS-CoV-2 in the cerebrospinal fluid. Our findings support previous reports suggesting seizure as a possible symptom of COVID-19 infection.

Hyperhomocysteinemia is related to large vessel occlusion in young patients with COVID-19: Two case reports.

Here, we report two cases of previously healthy young men with COVID-19 infection who developed acute ischemic stroke due to large vessel occlusion followed by secondary events concerning for a further thromboembolic event. We hypothesize that the hypercoagulable state related to COVID-19 exacerbated the underlying hereditary thrombophilia.

Guillain-Barré syndrome in association with COVID-19 vaccination: a systematic review.

Since the beginning of worldwide vaccination against coronavirus disease 2019 (COVID-19), studies have reported a possible association between vaccination and Guillain-Barré syndrome (GBS). In this regard, we conducted a systematic review assessing different demographic, clinical, and neurophysiological aspects of patients with GBS following immunization with COVID-19 vaccines. A comprehensive search of PubMed, Web of Science, Scopus, and Google Scholar was performed. Articles in English between January 2020 and November 2021 were included. Data on demographics, clinical characteristics, vaccines information, treatment approaches, and outcomes were extracted. The data of a total of 88 patients out of 41 studies was included. The mean age of patients was 58.7 ± 16.6 years and 55 cases (62.5%) were male. AstraZeneca was the most-reported vaccine associated with GBS with 52 cases (59.1%) followed by Pfizer with 20 cases (22.7%). GBS occurred after the first dose of vaccination in 70 cases (79.5%). The mean time interval between vaccination and symptom onset was 13.9 ± 7.4 days. Limb weakness (47.7%), sensory disturbance (38.6%), and facial weakness (27.3%) were the most common reported symptoms, respectively. Albuminocytologic dissociation was seen in 65% of patients who underwent lumbar puncture (n = 65). Acute inflammatory demyelinating polyradiculopathy was the most common GBS subtype, which was reported in 38 patients (43.2%). While one-fifth of patients underwent intubation (n = 17), a favorable outcome was achieved in the majority of subjects (n = 46, 63%). Overall, a small rise in GBS incidence, following various COVID-19 vaccines, was observed. Notably, 85% of affected individuals experienced at least a partial recovery.

Manifestation of Ocular Myasthenia Gravis as an Initial Symptom of Coronavirus Disease 2019: A Case Report.

For a while, coronavirus disease-2019 (COVID-19) has been a major global pandemic. It primarily affects the respiratory system but has extrapulmonary manifestations such as gastrointestinal and neurological symptoms. Data on myasthenia gravis (MG), as a complication of COVID-19, are limited. We herein report the manifestation of ocular MG as an initial symptom of COVID-19. In November 2020, a 31-year-old healthy woman was referred to Firoozgar Hospital (Tehran, Iran) with left upper eyelid ptosis and diplopia as well as general weakness, myalgia, fever, and nasal congestion for four days prior to admission. Although the acetylcholine receptor antibody in her serum was negative, increased jitter in several muscles led to the diagnosis of ocular MG. Nasal swab reverse transcription-polymerase chain reaction (RT-PCR) assay tested positive for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection. Computed tomography (CT) scan of the chest revealed bilateral ground-glass opacities and some foci of consolidation formation, but the thymus was normal. The patient was successfully treated with remdesivir and dexamethasone. The patient was eventually discharged in good condition and with improved neurological symptoms. A limited number of studies have suggested a possible association between MG and COVID-19. Therefore, further data are required to substantiate the proposed association. Clinicians should be aware of ocular MG during the COVID-19 pandemic to better diagnose and manage patients with SARS-CoV-2 infection.

Longitudinally extensive transverse myelitis after Covid-19 vaccination: case report and review of literature.

Mass vaccination has been the main policy to overcome the Covid-19 pandemic. Several vaccines have been approved by the World Health Organization. With growing vaccination, safety concerns and adverse events that need prompt evaluation are also emerging. Herein, we report a case of a healthy woman with longitudinally extensive transverse myelitis after vaccination with the AstraZeneca vaccine. The patient was successfully treated after ruling out all the possible causes.

Evaluating the correlation between migraine and subclinical atherosclerosis.

BACKGROUNDS AND AIMS: Migraine is known to be associated with vascular dysfunction. However, sufficient evidence has not been reported in this regard. This study aims to assess subclinical atherosclerosis and endothelial function via Doppler Sonography in migraine patients. METHODS: In this case control study, Subjects were divided into two groups; Patients with migraine, and Healthy controls. Migraine was diagnosed according to the International Classification of Headache Disorders criteria. Participants were evaluated for carotid intima-media thickness (IMT) and flow-mediated dilation (FMD) indices, and the findings were compared between the two groups. RESULTS: In the study population, 64.9 % were female, and the mean age was 34.63 ± 6.06 years. Of the 47 people with migraine, 12 suffered from migraine with aura. Increased IMT was more in migraine with and without aura compared to control (p = 0.247), and FMD was lower in these groups than the control group (p = 0.311). There was a significant correlation between the duration of headache with the duration of migraine (p = 0.007, 0.389) and IMT (p = 0.038, 0.303). No statistically significant differences were observed between NSAID, acetaminophen, and ergotamine groups with IMT (p = 0.532) and FMD (p = 0.834). CONCLUSION: Migraine and its related medications do not affect vascular changes in favor of atherosclerosis. However, these findings might be valid for patients with acute migraines only.
