Background: Migraine is associated with metabolic syndrome (MetS). There are evidences that components of MetS are more prevalent among migraine patients than non-migraineurs. Since both migraine and MetS are associated with a high risk of cardiovascular events, it is likely that the parameters of MetS increase the occurrence of cardiovascular disease (CVD) in migraineurs. The present research project was conducted for the purpose of investigating the relationship between MetS parameters and different items of migraine headaches. Methods: This descriptive-analytical, cross-sectional study was performed on 240 migraineurs [according to International Headache Society (HIS) II criteria] within the 17+ age range. The participants were selected via consecutive and convenience sampling method. The evaluated parameters for each subject included 2 arms: migraine characteristics (intensity, frequency of attacks, subtype, duration, and treatment regimen) and indices of MetS according to the National Cholesterol Education Program’s Adult Treatment Panel III (NCEP ATPIII) report criteria [high-density lipoprotein-cholesterol (HDL-C), triglyceride (TG), fasting plasma glucose (FPG), height, waist circumference (WC), systolic and diastolic blood pressure (BP), and body mass index (BMI)]. All data were analyzed in SPSS software. Results: Total prevalence of MetS was 16.25% (39 patients). There was a statistically meaningful relationship between hypertriglyceridemia and gender (P = 0.021), hypertriglyceridemia and prophylactic antimigraine regimen (P = 0.022), hyperglycemia and age group (P = 0.010), hyperglycemia and the intensity of headache (P = 0.048), hyperglycemia and prophylactic treatment (P = 0.001), systolic hypertension and migraine subtype (P = 0.004), systolic hypertension and the duration of migraine disease (P = 0.005), diastolic hypertension and migraine subtype (P = 0.002), WC and gender (P = 0.001), WC and the intensity of headache (P = 0.028), WC and prophylactic medication (P = 0.017), HDL and gender (P = 0.001), HDL and the prophylactic regimen (P = 0.023), and MetS and gender (P = 0.005). The prevalence of MetS was increased with increase in the severity of migraine headache. Conclusion: Due to the relative increase in the prevalence of MetS in patients with more severe migraine, an evaluation of the mechanisms of MetS is recommended in this population.

Background: One intriguing aspect of stroke is its higher incidence in men as compared to women. Endogenous sex hormones, testosterone and estradiol, may be responsible for this difference. This research aims to study serum testosterone and estradiol levels in men with acute ischemic stroke (AIS) and to correlate these levels with National Institutes of Health Stroke Scale (NIHSS) score and infarct size in computed tomography (CT).Methods: 100 male patients with AIS and 100 age-matched controls were included in this case-control study. Patients with hemorrhagic stroke, taking hormonal preparations, or suffering from chronic illnesses like tuberculosis (TB), cancer, etc. were excluded. Complete history was obtained including presence of established risk factors and physical examination was done in cases and controls with informed written consent. Severity of stroke in cases was assessed by the NIHSS. CT scan of brain was performed within 72 hours of patient’s admission to hospital. The infarct size was measured in centimeters as the largest visible diameter of the infarct on CT scan. Fasting blood samples were obtained for routine investigations and estimating estradiol and testosterone levels.Results: Mean total testosterone level in cases (223.30 ± 143.44 ng/dl) was significantly lower than that of controls (515.34 ± 172.11 ng/dl) (P < 0.001), while estradiol levels had no significant statistical difference (P = 0.260). A significant inverse correlation was found between total testosterone levels and stroke severity (r = -0.581, P < 0.001) and also, total testosterone levels and infarct size (r = -0.557, P < 0.001). Estradiol levels in patients had no significant correlation with stroke severity (P = 0.618) or infarct size (P = 0.463).Conclusion: Low testosterone levels are associated with increased stroke severity and infarct size in men. Further studies are required to establish whether low testosterone is a cause or effect of ischemic stroke and also to explore the potential benefits of testosterone supplementation in men with AIS.

Background: Rates of intracranial hemorrhage (ICH) after intravenous thrombolysis (IVT) differ depending on ethnicity, one reason that few Eastern countries have approved a lower dose of alteplase. Data in this regard are scarce in the Middle Eastern region. Methods: The present retrospective study was performed on data extracted from the Safe Implementation of Treatments in Stroke (SITS) registry. Computed tomography (CT) image analysis was based on the SITS-Monitoring Study (SITS-MOST) definition for symptomatic ICH (SICH). Functional outcome at 3 months was assessed using the modified Rankin Scale (mRS). Multivariate logistic regression including adjusted analysis was used for comparison between groups. Results: Of 6615 patients, 1055 were enrolled. A total of 86% (n = 906) received a standard dose and 14% (n = 149) received a low dose of alteplase. Favorable 3-month outcome was achieved in 481 (53%) patients in the standard group and 71 (48%) patients in the low-dose group [adjusted odds ratio (AOR) = 1.24, 95% confidence interval (CI): 0.87-1.75, P = 0.218]. SICH occurred in 14 (1.5%) patients in the standard group and 3 (2%) patients in the low-dose group [odds ratio (OR) = 2.77, 95% CI: 0.36-21.04, P = 0.120]. At 3 months, mortality occurred in 145 (16.0%) patients in the standard group and 29 (19.4%) patients in the low-dose group (OR = 1.22, 95% CI: 0.78-1.91, P = 0.346). Conclusion: Low-dose compared to standard-dose alteplase for patients with acute ischemic stroke (AIS) was not associated with fewer hemorrhagic events and there was no significant difference in the favorable 3-month outcome (mRS: 0-2) or mortality rate.

Background: Depression and anxiety are the most prevalent psychological symptoms in patients with multiple sclerosis (MS) and have a significant impact on quality of life (QOL) and disability progression in the patients. Therefore, it is very important to find ways to reduce the impact of these disorders on patients with MS. The data suggest that self-disclosure may be beneficial in improving symptoms of depression and anxiety in many chronic diseases. Due to the scarcity of related studies, this cross-sectional research aimed to evaluate the relations between self-disclosure, anxiety, and depression in patients with MS. Methods: 112 patients with MS from several referral outpatient MS clinics participated in the study. Data were extracted using socio-demographic questionnaire to determine clinical variables and patient characteristics, Distress Disclosure Index (DDI) to assess self-disclosure, Hospital Anxiety and Depression Scale (HADS) to evaluate mood states, and Kurtzke Expanded Disability Status Scale (EDSS) recorded by an experienced neurologist. Results: Multiple linear regression analysis with controlling disease variables demonstrated distress disclosure as an independent factor to predict anxiety and depression in the patients (P < 0.05). Results also presented a significant, positive relationship between hospitalization history and disability levels with anxiety and depression. These findings clearly state that these two variables can accurately predict a heightened state of anxiety and depression in patients with MS. Conclusion: This study provides empirical support for the positive role of disclosure in decreasing the negative emotions in MS. Further studies are needed to clarify the effects of disclosing MS in different cultural and situational contexts.

Background: Pediatric-onset multiple sclerosis (POMS) is an autoimmune demyelinating disorder of the central nervous system (CNS), affecting individuals younger than 18 years of age. We sought to characterize the epidemiological and clinical features of patients with POMS in Isfahan, Iran, from April 1997 to March 2020.Methods: The medical records of patients with POMS in the databases of Isfahan Department of Public Health and Isfahan Multiple Sclerosis Society (IMSS) were retrospectively reviewed. The 2006 and 2016 Isfahan Province population censuses were used as reference values for assessing the temporal trend of POMS.Results: From April 1997 to March 2020, 509 individuals under18 years of age were diagnosed with POMS in Isfahan. 404 of these patients (79.4%) were girls, and 105 patients (20.6%) were boys (a female to male ratio of 3.85:1). Most of the patients (83%) were monosymptomatic at onset, with optic neuritis and brainstem-cerebellar disorders being the most frequent initial presentations. Mean ± standard deviation (SD) of age at disease diagnosis was 15.8 ± 2.5 years (ranging from 3 to 18, mode = 18). From April 2019 to March 2020, the crude prevalence and the crude incidence rate of the POMS were 5.42 per 100000 and 1.86 per 100000, respectively. Poisson regression analysis revealed a 3.4% increase in the incidence rate of POMS from April 1997 to March 2020 [relative rate:1.034, 95% confidence interval (CI): 1.021-1.048].Conclusion: The female to male ratio in our cohort was significantly higher than any other studies conducted previously. The high female to male ratio and increasing incidence of the disease suggest increasing regionalization of care.

Background: Atherosclerotic involvement of large and small cerebral arteries leading to infarction is among the most prevalent subtypes of stroke worldwide. The hemodynamic changes due to these arterial pathologies can be studied non-invasively and in real-time by using transcranial Doppler (TCD) techniques. TCD indices of the studied arteries may guide the clinician in differentiating these two underlying arterial pathologies. Methods: A cross-sectional study of patients with small and large vessel types of cerebral infraction based on the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) stroke classification was undertaken in the inpatient population of neurology service of Razi Hospital, Tabriz, Iran, from October 2018 to October 2019. After clinical diagnosis, all cases underwent TCD studies, brain magnetic resonance imaging (MRI), and brain and cervical four-vessel magnetic resonance angiography (MRA). The results of TCD indices related to major arteries of the circle of Willis were tabulated and compared between large and small vessel subtypes of cerebral infarction. Results: A statistically significant difference between right middle cerebral artery (MCA) pulsatility index (PI), left MCA PI, right internal carotid artery (ICA) PI, end-diastolic velocity (EDV), left ICA PI, left ICA EDV, left anterior cerebral artery (ACA) PI, and right vertebral artery (VA) PI measures of the two groups was seen (P < 0.05). In comparison to the large vessel group, left ACA, right VA, and bilateral MCAs and ICAs in the small-vessel stroke group demonstrated an elevated PI. Conclusion: A significant increase of PI occurs in the majority of intracranial arteries of patients with small vessel stroke. This makes PI a valuable marker for differentiating strokes with different underlying pathophysiologies.

Background: Several surgical procedures such as excision or exclusion are recommended for the closure of the left atrial appendage (LAA). This study was conducted with the aim to evaluate the success rate of different surgical techniques for LAA closure, their respective complications, and the rate of post-surgical cerebrovascular accident (CVA). Methods: This retrospective study included 150 consecutive patients who underwent LAA closure most commonly after mitral valve surgery within 3 to 6 months after surgery. An expert echocardiographic fellow collected the data on patients’ surgical LAA closure methods and history of CVA, types of prosthetic valves, mortality, and bleeding. Results: The failure rate for complete LAA closure was 36.7% (55 patients) in our study. The greatest success rate of complete LAA closure was seen in purse-string method (75.5%), followed by resection method (71.4%), while the lowest success rate (≈ 33.3%) was observed in ligation method. A significant relationship was observed between clots on the surface of metallic valve and postoperative CVA (P = 0.001; likelihood ratio: 32). In multivariate analysis, there was also no statistically significant relationship between partial LAA closure and the incidence of post-surgical CVA (P > 0.050). Conclusion: We observed the highest success rate of complete LAA closure in purse-string method followed by resection method. Interestingly, our results showed that despite the higher rate of residual LAA clot in cases of partial LAA closure, the occurrence of post-surgical CVA was mostly related to the presence of clots on the surface of metallic mitral prostheses rather than the presence of partial LAA closure.

Background: The national multiple sclerosis (MS) registry is aimed at monitoring and improving quality of care and providing feedback to improve health outcomes by systematic recording of data. In 2018, the nationwide MS registry of Iran (NMSRI) was initiated for collecting epidemiological data and information on health care provision for patients with MS. The aim of the current study was to introduce the role of implementing coronavirus disease 2019 (COVID-19) scale-up registry protocol in NMSRI and arrange the national MS generality with information obtained during the COVID-19 pandemic. Methods: The NMSRI group set up a program with crucial elements to collect the data of patients with MS who developed COVID-19. All MS cases with confirmed diagnosis of COVID-19 were enrolled in this study. New elements were considered to be added into the dataset, including demographic characteristics, definite diagnosis of COVID-19 and its symptoms, history of comorbidities, history of medications and hospitalization, changes in magnetic resonance imaging (MRI), and infection outcomes. Results: The COVID-19 data collection program was designed in NMSRI to collect data of MS cases with COVID-19 infection. The data collection protocol was explained to neurologists through an online training workshop. To the date of the study, 21 centers from 17 provinces of Iran were involved in the COVID-19 databases promoting NMSRI and 612 participants were registered successfully. Conclusion: We extended an agreement on data collection and developed it in NMSRI with various contributors to discover a critical need for COVID-19 awareness and monitor clinical training in MS.
