Long-term colchicine for the prevention of vascular recurrent events in non-cardioembolic stroke (CONVINCE): a randomised controlled trial.

BACKGROUND: Anti-inflammatory therapy with long-term colchicine prevented vascular recurrence in coronary disease. Unlike coronary disease, which is typically caused by atherosclerosis, ischaemic stroke is caused by diverse mechanisms including atherosclerosis and small vessel disease or is frequently due to an unknown cause. We aimed to investigate the hypothesis that long-term colchicine would reduce recurrent events after ischaemic stroke. METHODS: We did a randomised, parallel-group, open-label, blinded endpoint assessed trial comparing long-term colchicine (0·5 mg orally per day) plus guideline-based usual care with usual care only. Hospital-based patients with non-severe, non-cardioembolic ischaemic stroke or high-risk transient ischaemic attack were eligible. The primary endpoint was a composite of first fatal or non-fatal recurrent ischaemic stroke, myocardial infarction, cardiac arrest, or hospitalisation (defined as an admission to an inpatient unit or a visit to an emergency department that resulted in at least a 24 h stay [or a change in calendar date if the hospital admission or discharge times were not available]) for unstable angina. The p value for significance was 0·048 to adjust for two prespecified interim analyses conducted by the data monitoring committee, for which the steering committee and trial investigators remained blinded. The trial was registered at ClinicalTrials.gov (NCT02898610) and is completed. FINDINGS: 3154 patients were randomly assigned between Dec 19, 2016, and Nov 21, 2022, with the last follow-up on Jan 31, 2024. The trial finished before the anticipated number of outcomes was accrued (367 outcomes planned) due to budget constraints attributable to the COVID-19 pandemic. Ten patients withdrew consent for analysis of their data, leaving 3144 patients in the intention-to-treat analysis: 1569 (colchicine and usual care) and 1575 (usual care alone). A primary endpoint occurred in 338 patients, 153 (9·8%) of 1569 patients allocated to colchicine and usual care and 185 (11·7%) of 1575 patients allocated to usual care alone (incidence rates 3·32 vs 3·92 per 100 person-years, hazard ratio 0·84; 95% CI 0·68-1·05, p=0·12). Although no between-group difference in C-reactive protein (CRP) was observed at baseline, patients treated with colchicine had lower CRP at 28 days and at 1, 2, and 3 years (p<0·05 for all timepoints). The rates of serious adverse events were similar in both groups. INTERPRETATION: Although no statistically significant benefit was observed on the primary intention-to-treat analysis, the findings provide new evidence supporting the rationale for anti-inflammatory therapy in further randomised trials.

Association between heavy alcohol consumption and cryptogenic ischaemic stroke in young adults: a case-control study.

BACKGROUND: The underlying risk factors for young-onset cryptogenic ischaemic stroke (CIS) remain unclear. This multicentre study aimed to explore the association between heavy alcohol consumption and CIS with subgroup analyses stratified by sex and age. METHODS: Altogether, 540 patients aged 18-49 years (median age 41; 47.2% women) with a recent CIS and 540 sex-matched and age-matched stroke-free controls were included. Heavy alcohol consumption was defined as >7 (women) and >14 (men) units per week or at least an average of two times per month ≥5 (women) and ≥7 (men) units per instance (binge drinking). A conditional logistic regression adjusting for age, sex, education, hypertension, cardiovascular diseases, diabetes, hypercholesterolaemia, current smoking, obesity, diet and physical inactivity was used to assess the independent association between alcohol consumption and CIS. RESULTS: Patients were twice as more often heavy alcohol users compared with controls (13.7% vs 6.7%, p<0.001), were more likely to have hypertension and they were more often current smokers, overweight and physically inactive. In the entire study population, heavy alcohol consumption was independently associated with CIS (adjusted OR 2.11; 95% CI 1.22 to 3.63). In sex-specific analysis, heavy alcohol consumption was associated with CIS in men (2.72; 95% CI 1.25 to 5.92), but not in women (1.56; 95% CI 0.71 to 3.41). When exploring the association with binge drinking alone, a significant association was shown in the entire cohort (2.43; 95% CI 1.31 to 4.53) and in men (3.36; 95% CI 1.44 to 7.84), but not in women. CONCLUSIONS: Heavy alcohol consumption, particularly binge drinking, appears to be an independent risk factor in young men with CIS.

Obesity and the Risk of Cryptogenic Ischemic Stroke in Young Adults.

OBJECTIVES: We examined the association between obesity and early-onset cryptogenic ischemic stroke (CIS) and whether fat distribution or sex altered this association. MATERIALS AND METHODS: This prospective, multi-center, case-control study included 345 patients, aged 18-49 years, with first-ever, acute CIS. The control group included 345 age- and sex-matched stroke-free individuals. We measured height, weight, waist circumference, and hip circumference. Obesity metrics analyzed included body mass index (BMI), waist-to-hip ratio (WHR), waist-to-stature ratio (WSR), and a body shape index (ABSI). Models were adjusted for age, level of education, vascular risk factors, and migraine with aura. RESULTS: After adjusting for demographics, vascular risk factors, and migraine with aura, the highest tertile of WHR was associated with CIS (OR for highest versus lowest WHR tertile 2.81, 95%CI 1.43-5.51; P=0.003). In sex-specific analyses, WHR tertiles were not associated with CIS. However, using WHO WHR cutoff values (>0.85 for women, >0.90 for men), abdominally obese women were at increased risk of CIS (OR 2.09, 95%CI 1.02-4.27; P=0.045). After adjusting for confounders, WC, BMI, WSR, or ABSI were not associated with CIS. CONCLUSIONS: Abdominal obesity measured with WHR was an independent risk factor for CIS in young adults after rigorous adjustment for concomitant risk factors.

Association of Vertebral Artery Hypoplasia and Vertebrobasilar Cerebrovascular Accident.

Background and Objectives: Vertebral artery hypoplasia (VAH) is a controversial risk factor for cerebral infarction. The aim of this study was to analyze the prevalence of vertebral artery hypoplasia and to evaluate its association with vertebrobasilar cerebrovascular accidents. Materials and Methods: The study was conducted in the Neurology Departments of the Republican Vilnius University Hospital from 2015 to 2020. Data of 742 subjects (133 patients with posterior circulation infarction or vertebral artery syndrome (PCI/VAS), 80 patients with anterior circulation infarction (ACI) and 529 control subjects with no symptoms of cerebrovascular accident) were analyzed. Ultrasound examination of the extracranial internal carotid and vertebral arteries (VA) was performed, risk factors were recorded. Results: The mean age of the subjects was 64.51 ± 13.02 years. In subjects with PCI/VAS the diameter of VA was smaller, and the prevalence of VAH was higher compared to those in subjects with ACI and in the control group. A higher degree of VAH in subjects younger than 65 years of age increased the risk of PCI/VAS. Subjects with non-dominant VA diameter of 2.7-2.9 mm had 2.21 times higher risk of PCI/VAS, subjects with non-dominant VA diameter of 2.5-2.6 mm had 2.36 times higher risk of PCI/VAS, and subjects with non-dominant VA diameter of 2.2-2.4 mm had 4.12 times higher risk of PCI/VAS compared with subjects with non-dominant VA diameter of ≥3 mm. Among patients with PCI/VAS those with VAH had lower rates of ischemic heart disease compared with patients with normal VA diameter. There was no difference in the rates of other risk factors between PCI/VAS patients with and without VAH. Conclusions: Vertebral artery hypoplasia is not a rare finding in individuals without symptoms of cerebrovascular accident, but more frequent in patients with vertebrobasilar cerebral infarction or vertebrobasilar artery syndrome. Vertebral artery hypoplasia can be considered a risk factor for posterior circulation infarction in subjects under 65 years of age.

Inflammatory Disorders of the Central Nervous System Vessels: Narrative Review.

Inflammatory disorders of the central nervous system (CNS) vessels, also called CNS vasculitides, can cause substantial disability or even be fatal. Inflammation of the CNS vessels can be caused by primary angiitis of the CNS (PACNS), inflammatory cerebral amyloid angiopathy, or systemic inflammatory disorders. Clinical symptoms of these disorders are often non-specific, such as encephalopathy, cognitive and affective abnormalities, headache and focal neurological symptoms. Diagnostic workup includes a thorough neuropsychiatric examination, blood and cerebrospinal fluid analysis and magnetic resonance imaging (MRI) of the brain and its vessels. Biopsy of the brain remains the gold standard diagnostic test. Timely diagnosis and treatment initiation is of high importance, as it might prevent severe complications, such as ischemic and hemorrhagic stroke. In this review, we describe the specific characteristics of primary and secondary non-infectious CNS vasculitides which help to establish the diagnosis, discuss the peculiarities of the diagnostic workup and present current treatment recommendations.

Endovascular Treatment of Basilar Artery Occlusion: What Can We Learn from the Results?

Background and Objectives: Current guidelines lack specific endovascular treatment (EVT) recommendations for posterior circulation stroke (PCS). The results of earlier studies are controversial. We aimed to compare early hospital outcomes of stroke caused by large-vessel occlusion (LVO) treated with EVT or bridging therapy (BT) in anterior circulation stroke (ACS) versus PCS (middle cerebral artery occlusion (MCAO) and basilar artery occlusion (BAO), and establish the risk factors for poor outcome. Materials and Methods: we analyzed the data of 279 subjects treated with EVT due to LVO-caused stroke in a comprehensive stroke centre in 2015−2021. The primary outcome was hospital mortality, secondary outcomes were National Institutes of Health Stroke Scale (NIHSS) after 24 h, early neurological deterioration, futile recanalization (FR), the ambulatory outcome at discharge, and complications. Results: BAO presented with higher baseline NIHSS scores (19 vs. 14, p < 0.001), and longer door-to-puncture time (93 vs. 82 min, p = 0.034), compared to MCAO. Hospital mortality and the percentage of FR were the same in BAO and almost two times higher than in MCAO (20.0% vs. 10.3%, p = 0.048), other outcomes did not differ. In BAO, unsuccessful recanalization was the only significant predictor of the lethal outcome, though there were trends for PAD and RF predicting lethal outcome. A trend for higher risk of symptomatic intracranial hemorrhage (sICH) was observed in the BAO group when BT was applied. Nevertheless, neither BT nor sICH predicted lethal outcomes in the BAO group. Conclusions: Compared to the modern gold standard of EVT in the ACS, early outcomes in BAO remain poor, there is a substantial amount of FR. Nevertheless, unsuccessful recanalization remains the strongest predictor of lethal outcomes. BT in PCS might pose a higher risk for sICH, but not the lethal outcome, although this finding requires further investigation in larger trials.

High Prevalence of Atrial Fibrillation in a Lithuanian Stroke Patient Cohort.

Background and Objectives: Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with a five-fold increased risk for acute ischemic stroke (AIS). We aimed to estimate the prevalence of AF in a Lithuanian cohort of stroke patients, and its impact on patients regarding case fatality, functional outcome, and health-related quality of life (HRQoL) at 90 days. Materials and Methods: A single-center prospective study was carried out for four non-consecutive months between December 2018 and July 2019 in one of the two comprehensive stroke centers in Eastern Lithuania. A telephone-based follow-up was conveyed at 90 days using the modified Rankin Scale (mRS) and EuroQoL five-dimensional three-level descriptive system (EQ-5D-3L) with a self-rated visual analog scale (EQ-VAS). One-year case fatality was investigated. Results: We included 238 AIS patients with a mean age of 71.4 ± 11.9 years of whom 45.0% were female. A striking 97 (40.8%) AIS patients had a concomitant AF, in 68 (70.1%) of whom the AF was pre-existing. The AIS patients with AF were at a significantly higher risk for a large vessel occlusion (LVO; odds ratio 2.72 [95% CI 1.38−5.49], p = 0.004), and had a more severe neurological impairment at presentation (median NIHSS score (interquartile range): 9 (6−16) vs. 6 (3−9), p < 0.001). The LVO status was only detected in those who had received computed tomography angiography. Fifty-five (80.9%) patients with pre-existing AF received insufficient anticoagulation at stroke onset. All patients received a 12-lead ECG, however, in-hospital 24-h Holter monitoring was only performed in 3.4% of AIS patients without pre-existing AF. Although multivariate analyses found no statistically significant difference in one-year stroke patient survival and favorable functional status (mRS 0−2) at 90 days, when adjusted for age, gender, reperfusion treatment, baseline functional status, and baseline NIHSS, stroke patients with AF had a significantly poorer self-perceived HRQoL, indicated by a lower EQ-VAS score (regression coefficient ± standard error: ß = −11.776 ± 4.850, p = 0.017). Conclusions: In our single-center prospective observational study in Lithuania, we found that 40.8% of AIS patients had a concomitant AF, were at a higher risk for an LVO, and had a significantly poorer self-perceived HRQoL at 90 days. Despite the high AF prevalence, diagnostic tools for subclinical AF were greatly underutilized.

Subspecialty training of neurology residents and junior neurologists in the Baltic States.

BACKGROUND: Neurology is a field of increasing subspecialization. There is no published data regarding the proportion of neurology subspecialists in the Baltic States. The aim of this cross-sectional study was to identify factors associated with neurology subspecialty choice, to examine possible differences between neurology residents' and junior neurologists' view of subspecialty, and to assess perceived subspecialty acquisition opportunities and subspecialty attractiveness. METHODS: The research was conducted as an anonymous online survey between December 28, 2020, and January 24, 2021 of neurology residents and neurologists who completed their residency during the last 5 years in the Baltic States. RESULTS: In total, 72 residents and 65 neurologists participated. "Cerebrovascular diseases" and "multiple sclerosis and autoimmune diseases of the nervous system" were rated as the two most attractive subspecialties by residents, whereas "headache" and "clinical neurophysiology" were the most attractive among junior neurologists. "Vertigo and dizziness" and "dementia" were ranked the least attractive among both groups. "Cerebrovascular diseases" were perceived as having the most acquisition opportunities. The two most common determinants of subspecialty choice were "medical content of the subspecialty" and "influence of mentor during undergraduate studies or residency". CONCLUSIONS: Two-thirds of junior neurologists subspecialize in at least one subspecialty, and one-third of residents are already determined to pursue subspecialty training. Junior neurologists rated most outpatient-related subspecialties as more attractive than neurology residents. Between the Baltic States' universities, there was a significant difference in the number of residents who were determined to pursue subspecialty training.

Safety and Outcomes of Intravenous Thrombolysis in Posterior Versus Anterior Circulation Stroke: Results From the Safe Implementation of Treatments in Stroke Registry and Meta-Analysis.

Background and Purpose- Posterior circulation stroke (PCS) accounts for 5% to 19% of patients with acute stroke receiving intravenous thrombolysis. We aimed to compare safety and outcomes following intravenous thrombolysis between patients with PCS and anterior circulation stroke (ACS) and incorporate the results in a meta-analysis. Methods- We included patients in the Safe Implementation of Treatments in Stroke Thrombolysis Registry 2013 to 2017 with computed tomography/magnetic resonance angiographic occlusion data. Outcomes were parenchymal hematoma, symptomatic intracerebral hemorrhage (SICH) per SITS-MOST (Safe Implementation of Thrombolysis in Stroke Monitoring Study), ECASS II (Second European Co-operative Stroke Study) and NINDS (Neurological Disorders and Stroke definition), 3-month modified Rankin Scale score, and death. Adjustment for SICH risk factors (age, sex, National Institutes of Health Stroke Scale, blood pressure, glucose, and atrial fibrillation) and center was done using inverse probability treatment weighting, after which an average treatment effect (ATE) was calculated. Meta-analysis of 13 studies comparing outcomes in PCS versus ACS after intravenous thrombolysis was conducted. Results- Of 5146 patients, 753 had PCS (14.6%). Patients with PCS had lower median National Institutes of Health Stroke Scale: 7 (interquartile range, 4-13) versus 13 (7-18), P<0.001 and fewer cerebrovascular risk factors. In patients with PCS versus ACS, parenchymal hematoma occurred in 3.2% versus 7.9%, ATE (95% CI): -4.7% (-6.3% to 3.0%); SICH SITS-MOST in 0.6% versus 1.9%, ATE: -1.4% (-2.2% to -0.7%); SICH NINDS in 3.1% versus 7.8%, ATE: -3.0% (-6.3% to 0.3%); SICH ECASS II in 1.8% versus 5.4%, ATE: -2.3% (-5.3% to 0.7%). In PCS versus ACS, 3-month outcomes (70% data availability) were death 18.5% versus 20.5%, ATE: 6.0% (0.7%-11.4%); modified Rankin Scale score 0-1, 45.2% versus 37.5%, ATE: 1.7% (-6.6% to 3.2%); modified Rankin Scale score 0-2, 61.3% versus 49.4%, ATE: 2.4% (3.1%-7.9%). Meta-analysis showed relative risk for SICH in PCS versus ACS being 0.49 (95% CI, 0.32-0.75). Conclusions- The risk of bleeding complications after intravenous thrombolysis in PCS was half that of ACS, with similar functional outcomes and higher risk of death, acknowledging limitations of the National Institutes of Health Stroke Scale for stroke severity or infarct size adjustment.

Intravenous r-tPA Dose Influence on Outcome after Middle Cerebral Artery Ischemic Stroke Treatment by Mechanical Thrombectomy.

Background and Objectives: Pretreatment with intravenous thrombolysis (IVT) is still recommended in all eligible acute ischemic stroke patients with large-vessel occlusion before mechanical thrombectomy (MTE). However, the added value and safety of bridging therapy versus direct MTE remains controversial. We aimed at evaluating the influence of r-tPA dose level in patients with middle cerebral artery (MCA) occlusion treated with MTE. Materials and Methods: We prospectively compared clinical and radiological outcomes in 38 bridging patients, with 65 receiving direct MTE for MCA stroke admitted to Vilnius University Hospital Santaros Clinics. Following our protocol, r-tPA infusion was stopped just before MTE in the operating room. Therefore, we divided all bridging patients into three groups according to the amount of r-tPA they received: bolus, partial dose or full dose. Functional independence at 90 days was assessed by a modified Rankin Scale score, i.e., from 0-2. The safety outcomes included 90-day mortality and any intracerebral hemorrhage (ICH). Results: Baseline characteristics and functional outcome at 90 days did not differ between the bridging and direct MTE groups. Shorter MTE procedure and hospitalization time (p = 0.025 and p = 0.036, respectively) were observed in the direct MTE group. An IVT treatment subgroup analysis showed higher rates of symptomatic ICH (p < 0.001) and longer intervals between imaging to MTE (p = 0.005) in the full r-tPA dose group. Conclusions: In patients with an MCA stroke, direct MTE seems to be a safe and equally effective as bridging therapy. The optimal r-tPA dose remains unclear. Randomized trials are needed to accurately evaluate the added value of r-tPA in patients treated with MTE.

Diagnosis and treatment choices of suspected benign paroxysmal positional vertigo: current approach of general practitioners, neurologists, and ENT physicians.

PURPOSE: Benign paroxysmal positional vertigo (BPPV) is a frequently underdiagnosed cause of vertigo, potentially due to the underuse of diagnostic and therapeutic canalith repositioning procedures (CRPs). We aimed to investigate self-reported use of the diagnostic and therapeutic approach to BPPV patients by Lithuanian neurologists, ear, nose, and throat (ENT) physicians, and general practitioners (GPs), and to explore potential reasons for the underuse of the maneuvers. METHODS: Neurologists, ENT physicians, and GPs were invited to complete a written questionnaire focused on diagnostic and therapeutic practices related to BPPV. Between-group differences and associations between responses were analyzed statistically. RESULTS: In total, 97 neurologists, 85 ENT physicians and 142 GPs (21.1%, 26.8%, and 5.7%, respectively, of all corresponding licensed Lithuanian physicians) completed the questionnaire. 24% of neurologists, 33% ENT physicians and 50% GPs do not perform diagnostic maneuvers for patients with suspected BPPV, and 28%, 61%, and 84%, respectively, do not perform CRPs. Years of clinical experience was a negative predictor of CRP performance [OR 0.97 (95% CI 0.95-0.99), p = 0.001]. Frequent reasons for not performing CRPs were time taken for the procedure, fear of provoking symptoms, and lack of knowledge. All physicians frequently ordered additional imaging or consultations for suspected BPPV and reported prescribing a range of medications. CONCLUSIONS: A significant proportion of Lithuanian neurologists, ENT physicians, and GPs do not employ diagnostic maneuvers and CRPs for BPPV patients, contrary to established guidelines. Lack of expertise and time available is a common culprit that leads to unnecessary drug prescribing and investigation.

Epidural Analgesia and Back Pain after Labor.

Background and Objectives: The aim of this survey was to assess the impact of epidural analgesia on post-partum back pain in post-partum women. Materials and Methods: The questionnaire was completed by post-partum women during the first days after delivery. Six months later, the women were surveyed again. The response rate was 70.66%, a total of 212 cases were included in the statistical analysis. The statistical analysis of the data was conducted using SPSS® Results. Seventy-nine (37.26%) women received epidural analgesia, 87 (41.04%) intravenous drugs, and 46 (21.7%) women gave birth without anesthesia. The prevalence of post-partum back pain was observed in 24 (30.38%) women of the epidural analgesia group, in 24 (27.58%) subjects of the intravenous anesthesia group, and in 14 (30.43%) women attributed to the group of subjects without anesthesia. The correlation between post-partum back pain and the type of anesthesia was not statistically significant (p = 0.907). Six months later, the prevalence of back pain was found in 31.65% of women belonging to the epidural analgesia group, in 28.74% of women with intravenous anesthesia, and in 23.91% of women without anesthesia. The correlation between complaints of back pain six months after delivery and the type of anesthesia applied was not statistically significant (p = 0.654). Conclusions. The labor pain relief technique did not trigger the increased risk of back pain in the early post-partum period and six months after delivery.

Family and sexual life in people with epilepsy.

Having epilepsy is much more than having seizures. Epilepsy can have a severe negative effect on quality of life, affecting social relationships, academic achievement, housing, employment, and the ability to live and function independently. We undertook a cross-sectional study in a tertiary epilepsy center in Lithuania, aiming to assess the influence of epilepsy and aspects relating to epilepsy (employment, stigma, anxiety) on patients and their families, and to estimate their quality of family life and sexual functioning. We asked patients to complete a questionnaire about their socio-demographic situation, their seizure types and antiepileptic medications, and their quality of family and sexual life. Our results confirmed that epilepsy seriously influences family life. One third of our patients are lonely and half are childless. Epilepsy leads to difficulty in finding a job, especially for men, and unemployment affects their status in the family. People with epilepsy are uncomfortable interacting with those of the opposite sex and tend to conceal their medical condition from their partner. One third have sexual dysfunction, yet only a quarter of them seek professional help. There is a clear need to improve self-confidence and to reduce social stigma in people with epilepsy, and to encourage them to discuss their problems with specialists.

Descriptions of Apoplexy by Joseph Frank in the Beginning of the Nineteenth Century in Vilnius.

In the beginning of the 19th century, apoplexy was understood to be a disease of the cerebral blood vessels, manifesting with a sudden weakening or extinction of sensation and the patient's inability to move. In this study, we examined the situation of neurology in the beginning of the 19th century in Vilnius through the perspective of a nervous system disease - apoplexy. Case reports and descriptions of apoplexy in the textbook and memoirs by Joseph Frank (1771-1842), descriptions of patients with apoplexy from the proceedings of Vilnius University Clinic were analysed. It was identified that the main cause of apoplexy was not an imbalance of the four humours but the pathology of cerebral blood vessels. However, following ancient tradition, the principles of recreation and moderation were thought to be important for the prevention of apoplexy, and bloodletting and diet were believed to be essential for the treatment.

Intravenous Thrombolysis for Stroke Recurring Within 3 Months From the Previous Event.

BACKGROUND AND PURPOSE: According to the European license, alteplase can be given no sooner than 3 months after previous stroke. However, it is not known whether past history of stroke influences the effect of treatment. Our aim was to evaluate safety and functional outcome after intravenous thrombolysis administered in everyday practice to patients with previous stroke≤3 months compared with those with first-ever stroke. METHODS: We analyzed consecutive cases treated with alteplase between October 2003 and July 2014 contributed to the Safe Implementation of Thrombolysis for Stroke-Eastern Europe registry from 12 countries. Odds ratios were calculated using unadjusted and adjusted logistic regression. RESULTS: Of 13,007 patients, 11,221 (86%) had no history of stroke and 249 (2%) experienced previous stroke≤3 months before admission. Patients with previous stroke≤3 months had a higher proportion of hypertension and hyperlipidemia. There were no significant differences in outcome, including symptomatic intracerebral hemorrhage according to European Cooperative Acute Stroke Study (unadjusted odds ratio 1.27, 95% confidence interval: 0.74-2.15), and being alive and independent at 3 months (odds ratio 0.81, 95% confidence interval: 0.61-1.09). CONCLUSIONS: Patients currently treated with alteplase, despite a history of previous stroke≤3 months, do not seem to achieve worse outcome than those with first-ever stroke. Although careful patient selection was probably of major importance, our findings provide reassurance that this group of patients may safely benefit from thrombolysis and should not be arbitrarily excluded as a whole. Further studies are needed to identify the shortest safe time lapse from the previous event to treatment with alteplase.

Safety of Statin Pretreatment in Intravenous Thrombolysis for Acute Ischemic Stroke.

BACKGROUND AND PURPOSE: A recent meta-analysis investigating the association between statins and early outcomes in acute ischemic stroke (AIS) patients treated with intravenous thrombolysis (IVT) indicated that prestroke statin treatment was associated with increased risk of 90-day mortality and symptomatic intracranial hemorrhage. We investigated the potential association of statin pretreatment with early outcomes in a large, international registry of AIS patients treated with IVT. METHODS: We analyzed prospectively collected data from the Safe Implementation of Treatments in Stroke-East registry (SITS-EAST) registry on consecutive AIS patients treated with IVT during an 8-year period. Early clinical recovery within 24 hours was defined as reduction in baseline National Institutes of Health Stroke Scale score of ≥10 points. Favorable functional outcome at 3 months was defined as modified Rankin Scale scores of 0 to 1. Symptomatic intracranial hemorrhage was diagnosed using National Institute of Neurological Disorders and Stroke, European-Australasian Acute Stroke Study-II and SITS definitions. RESULTS: A total of 1660 AIS patients treated with IVT fulfilled our inclusion criteria. Patients with statin pretreatment (23%) had higher baseline stroke severity compared with cases who had not received any statin at symptom onset. After adjusting for potential confounders, statin pretreatment was not associated with a higher likelihood of symptomatic intracranial hemorrhage defined by any of the 3 definitions. Statin pretreatment was not related to 3-month all-cause mortality (odds ratio, 0.92; 95% confidence interval, 0.57-1.49; P=0.741) or 3-month favorable functional outcome (odds ratio, 0.81; 95% confidence interval, 0.52-1.27; P=0.364). Statin pretreatment was independently associated with a higher odds of early clinical recovery (odds ratio, 1.91; 95% confidence interval, 1.25-2.92; P=0.003). CONCLUSIONS: Statin pretreatment seems not to be associated with adverse outcomes in AIS patients treated with IVT. The effect of statin pretreatment on early functional outcomes in thrombolysed AIS patients deserves further investigation.

Prevalence of cardiovascular risk factors in Lithuanian middle-aged subjects participating in the primary prevention program, analysis of the period 2009-2012.

BACKGROUND: The aim of this study was to assess the prevalence and changes of cardiovascular risk factors in the middle-aged Lithuanian subjects after conducting the primary prevention program. DESIGN AND METHODS: Four cross-sectional investigations of cardiovascular risk factors were conducted in 2009 (n = 9625), 2010 (n = 7716), 2011 (n = 5018) and 2012 (n = 4348). The program recruited men aged 40-54 and women aged 50-64 without overt cardiovascular disease. RESULTS: During the period 2009-2012, the mean number of risk factors significantly increased (from 3.95 to 4.03, p < 0.001), while the numbers of people having metabolic syndrome (from 34.1% to 28.7%; p < 0.001), arterial hypertension (from 60.2% to 54.5%; p < 0.001), the average body mass index (BMI) value (from 29.17 to 28.92 kg/m(2); p = 0.001) and abdominal obesity (from 48.4% to 45.3%; p < 0.001) significantly decreased. The percentage of subjects with dyslipidemia, as well as the average values of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglycerides, remained unchanged. The percentage of smoking subjects have significantly increased (from 19.3% to 22.7%; p < 0.001). CONCLUSIONS: The analysis showed that the prevalence of arterial hypertension, metabolic syndrome and obesity in Lithuania is slowly decreasing while conducting the primary prevention program; however, dyslipidemia, diabetes mellitus and smoking are still hard to manage for both genders.

Role of preexisting disability in patients treated with intravenous thrombolysis for ischemic stroke.

BACKGROUND AND PURPOSE: Little is known about the effect of thrombolysis in patients with preexisting disability. Our aim was to evaluate the impact of different levels of prestroke disability on patients' profile and outcome after intravenous thrombolysis. METHODS: We analyzed the data of all stroke patients admitted between October 2003 and December 2011 that were contributed to the Safe Implementation of Treatments in Stroke-Eastern Europe (SITS-EAST) registry. Patients with no prestroke disability at all (modified Rankin Scale [mRS] score, 0) were used as a reference in multivariable logistic regression. RESULTS: Of 7250 patients, 5995 (82%) had prestroke mRS 0, 791 (11%) had prestroke mRS 1, 293 (4%) had prestroke mRS 2, and 171 (2%) had prestroke mRS≥3. Compared with patients with mRS 0, all other groups were older, had more comorbidities, and more severe neurological deficit on admission. There was no clear association between preexisting disability and the risk of symptomatic intracranial hemorrhage. Prestroke mRS 1, 2, and ≥3 were associated with increased risk of death at 3 months (odds ratio, 1.3, 2.0, and 2.6, respectively) and lower chance of achieving favorable outcome (achieving mRS 0-2 or returning to the prestroke mRS; 0.80, 0.41, 0.59, respectively). Patients with mRS≥3 and 2 had similar vascular profile and favorable outcome (34% versus 29%), despite higher mortality (48% versus 39%). CONCLUSIONS: Prestroke disability does not seem to independently increase the risk of symptomatic intracranial hemorrhage after thrombolysis. Despite higher mortality, 1 in 3 previously disabled patients may return to his/her prestroke mRS. Therefore, they should not be routinely excluded from thrombolytic therapy.

Prevalence of high-risk profile in middle-aged subjects with arterial hypertension: a nationwide survey.

Hypertension is the most common non-communicable disease and the leading cause of cardiovascular disease in the world. It presents an important public health challenge in both economically developed and developing countries. In 2006, the Lithuanian High Cardiovascular Risk programme was launched. The programme recruited men aged 40-54 and women aged 50-64 without overt cardiovascular disease. We analysed a group of 23,204 subjects included in the programme at the primary level. Arterial hypertension was present in 57.6% of the subjects: 63.2% in the females and 49.2% in the males. In the hypertensive middle-aged subjects, grade 1 hypertension was present in 53.1%, grade 2 in 22.4%, and grade 3 in merely 5.9% of the subjects. The prevalence of a minimum of three concomitant risk factors among the hypertensive patients was 78.0%, compared with 52.1% in the patients without hypertension (p < 0.001). Blood pressure goals were attained in 20.8% of the hypertensive women and in 14.4% of the hypertensive men. In Lithuania, a high prevalence of hypertension was characteristic of middle-aged subjects. Although the blood pressure elevation had not reached high levels, the presence of at least three risk factors concomitant to hypertension was more expressed in them compared with the non-hypertensive subjects.

Can International Classification of Functioning, Disability and Health (ICF) Be Used for Prediction of Work Capacity and Employment Status in Multiple Sclerosis?

Background: Multiple sclerosis (MS) affects many body functions and activities, including work capacity and ability to work. An evaluation of work-related parameters is important to understand the barriers to maintaining the job. The aim of this study was to evaluate if a Comprehensive International Classification of Functioning, Disability and Health (ICF) core set for MS can be used to predict work capacity and employment status. Methods: The cohort included 151 participants with MS (99 female/52 male, mean age 49 years) referred for a work capacity evaluation. Results: 71 (47.0%) were employed and a major part (131, 86.7%) had a work capacity between 20 and 40% with no difference between those who were employed and those who were unemployed. The analysis revealed that age and the following categories explained 68.8% of the work capacity: b770 Gait pattern functions; b730 Muscle power functions; b134 Sleep functions; d845 Acquiring, keeping and terminating a job; and b620 Urination functions. The following categories in 79.5% predicted ability to work: b164 Higher-level cognitive functions; d510 Washing oneself; d630; Preparing meals; and d870 Economic self-sufficiency. Conclusions: Here, we show that different functions/activities predicted work capacity in comparison with employment status in MS. Therefore, ICF should be implemented when assessing work ability.
