Effectiveness of statins on outcomes of patients with Embolic Stroke of Undetermined Source (ESUS).

BACKGROUND: Statins are highly recommended as a secondary prevention strategy after a stroke. Embolic Stroke of Undetermined Source (ESUS) accounts for up to one fifth of cases of ischemic stroke. There is a lack of studies investigating the effectiveness of statins in this subgroup of patients. METHODS: We designed a longitudinal cohort study involving patients properly diagnosed with ESUS. Data about statin therapy included information about the time of initiation of the treatment, pre-stroke statin use, statin withdrawal, and the type and dosage of the statin prescribed. Patients were followed for 48 months after the index stroke. The primary endpoints included stroke recurrence, major cardiovascular events, and death from all causes. The secondary endpoint was the functional outcome, assessed in a standardized and systematic way using the modified Rankin Scale (mRS). RESULTS: Patients who were not taking any statin after ESUS have significantly increased odds of stroke recurrence (OR = 3.29, 95% CI 1.27 - 8.55) or presenting the composite outcome of stroke recurrence, major cardiovascular events, and death (OR = 3.70, 95% CI 1.44 - 9.50) in the multivariate analysis. No statin therapy was directly associated with the functional outcome as well (OR = 3.32, 95% CI = 1.58 - 6.96). The early initiation of the statin therapy was estimated to reduce the risk of a second stroke and the composite outcome by 89% and 87%. CONCLUSIONS: Our pioneering study provides evidence that patients with ESUS may benefit from statin therapy, especially if prescribed early and at higher dosages.

Job Retention by People With Disabilities: A Qualitative Study of the Perspectives of People With Multiple Sclerosis.

BACKGROUND: Multiple sclerosis (MS), because of its early age at onset, greatly impacts the working lives of those affected by it in ways linked to different factors, both professional and personal. It has been observed that only a small percentage (20-40%) of workers with MS retain their jobs after the diagnosis. When identifying factors determining job retention or loss in this setting, it is essential to consider the direct perspectives of people with MS (PwMS). METHODS: A qualitative study, based on the conduction of two focus groups, was conducted to explore the personal experiences of PwMS who work. RESULTS: The results show that there are numerous factors, both positive and negative, that can influence these people's ability to retain their jobs. The climate established in the workplace and the relationship between workers with MS and their colleagues were fundamentally important aspects, as was knowledge of the disease at the level of public opinion. CONCLUSIONS: Managing work is a complex undertaking for people with a disabling condition like MS. There needs to be greater awareness of the employment rights of PwMS. Improving these knowledge-based aspects could undoubtedly improve the quality of the working lives of PwM.

Work Difficulties in People with Multiple Sclerosis.

PURPOSE: This study identifies potential predictors of unemployment and describes specific work difficulties and their determinants in a subgroup of employed people with multiple sclerosis (PwMS). The specific work difficulties were evaluated using a validated tool that measures the impact of respondents' symptoms and of workplace features. METHODS: A cross-sectional study was carried out in Italy during 2021-2022. The subjects included were adults (18-65 years) with a diagnosis of MS, currently employed or unemployed. Logistic regression models were used to determine the association between each potential determinant and employment status, while linear regression models were used to determine the association between determinants and specific work difficulties. RESULTS: The main risk factors associated with a higher risk of being unemployed were being older, living in the South of Italy/islands, and having a higher disability level, while protective factors against unemployment were having a high level of education and 'stable' employment (an open-ended contract). Fatigue was found to be associated with all work difficulties analyzed; mood disorders emerged as the main predictors of mental health-related work difficulties; level of disability and comorbidity significantly impacted physical health-related ones, and a good quality of life was found to improve both workplace-related and mental health-related difficulties at work. CONCLUSION: Identifying the most significant difficulties is a crucial step in the development of vocational rehabilitation interventions tailored to maximize the ability of PwMS to handle their job-related duties and demands.

Work Barriers and Job Adjustments of People with Multiple Sclerosis: A Systematic Review.

Purpose The aim was to carry out a systematic review dedicated to describing the work barriers and the job adjustments that are particularly sensitive to people with Multiple Sclerosis (PwMS). Methods Four electronic databases (PubMed/MEDLINE, Scopus, SciVerse ScienceDirect, and Web of Science) were searched for peer-reviewed original articles reporting the barriers at work and/or the job adjustments used by PwMS. MS must have been diagnosed according to accepted international criteria at the time of the study and/or confirmed by a doctor. No time limits were set for the search. Articles that were published in English, Italian, Spanish, French, and Portuguese were accepted. Each article was screened by three experienced and trained investigators. The protocol was registered in PROSPERO (CRD42022299994). Results The initial systematic search yielded 104,228 results, of which 49 articles provided sufficient information and were considered suitable for inclusion in the study. Overall, the studies included 30283 participants with MS. Thirteen (27.1%) studies reported on barriers to work, 14 (29.2%) addressed reasonable adjustments and 21 (43.7%) assessed both outcomes. Job characteristics are the most important barriers for PwMS. Other reported barriers concern the work environment, social relationships at work, negative work events and lack of information. PwMS are more vulnerable to the need for adjustments at the workplace, being the management of the workload the most commonly used one. Conclusions PwMS are exposed to a wide variety of work barriers and job adjustments. Future studies are still highly encouraged on the topic.

The influence of statin withdrawal and adherence on stroke outcomes.

INTRODUCTION: With multiple proven benefits, statin therapy has become the most critical advance in stroke prevention. We aimed to evaluate the risk factors and the effect of poor adherence or statin interruption on the clinical outcomes of ischemic stroke. METHODS: This prospective cohort study included patients admitted with acute ischemic stroke between 2014 and 2018. Consecutive patients were distinguished into subgroups according to the adherence and withdrawal of statin. All participants were followed for 24 months. The outcomes included stroke recurrence, major cardiovascular events, all-cause mortality, and functional performance. Functional outcome was assessed using the modified Rankin Scale at 7 days, 30 days, 6 months, and 2 years after hospital admission for ischemic stroke. In a secondary analysis, outcome variables were compared with statin-naïve patients. RESULTS: We included 479 patients with acute ischemic stroke. The mean age was 58.3, and 55.0% were male. There were 96 (21.8%) patients who received no statin, 150 (34.9%) patients with poor adherence, 40 (9.1%) patients with intermediate adherence, and 154 (35.0%) patients with good adherence. There were 54 (15.7%) cases of withdrawal of treatment. Patients with hypertension, previous stroke, and large-artery atherosclerosis were associated with poor adherence (p < 0.05). Those with poor adherence were significantly associated with worse functional outcomes and a higher incidence of stroke recurrence (p < 0.05). Significant functional recovery was just seen in patients with satisfactory adherence. CONCLUSION: The suboptimal use of statins is associated with significantly worse clinical outcomes in stroke patients.

Social, professional and neuropsychiatric outcomes in patients with myasthenia gravis.

BACKGROUND: Recent medical advances have enabled the control of neurological symptoms and increased survival of patients with myasthenia gravis (MG). However, MG has many veiled consequences that may be underestimated by neurologists. Our aim was to clarify the social, professional, and neuropsychiatric issues of MG patients. METHODS: We carried out a cross-sectional cohort study with MG patients from a university-affiliated referral hospital. We registered clinical and sociodemographic data, and patients were classified according the MGFA classification. Clinical severity was assessed with Myasthenia Gravis Composite (MGC) scale. Trained and blind investigators analyzed social and professional outcomes. Neuropsychiatric symptoms were evaluated with the Hospital Anxiety and Depression Scale (HADS) and the social support with the Multidimensional Scale of Perceived Social Support (MSPSS). RESULTS: We enrolled 49 patients with MG. The mean age was 45.3 ± 18.1 years and 39 (79.6%) were women. There were 19 (38.8%) patients who become unemployed, 23 (46.9%) who had to retire prematurely, 31 (63.3%) that reported a significant reduction in work performance, and 23 (46.9%) who had a reduction in monthly income after the diagnosis of MG. Only 16 (32.6%) received any financial support and 24 (48.9%) patients had the perception of receiving a satisfactory social support. The practice of physical activity is a habit in only 10 patients (20.4%). Neuropsychiatric symptoms were present in 26 (53.1%) patients. CONCLUSION: Patients with MG are vulnerable to social, professional, and mental disadvantages. Therapeutic success in MG goes beyond symptom relief and inevitably depends on a personalized approach to the patient.

Prevalence and Predictors of Fatigue and Neuropsychiatric Symptoms in Patients with Minor Ischemic Stroke.

OBJECTIVES: Patients who are victims of a mild stroke are vulnerable to several invisible and neglected neurological sequelae. In parallel, it is known that fatigue and neuropsychiatric symptoms are common complications after a stroke in general. Our aim was to describe the prevalence and the factors associated with these two outcomes after a minor stroke. MATERIALS AND METHODS: We conducted a prospective observational cohort study that included consecutive patients diagnosed with minor ischemic stroke between 2015 and 2019. Minor stroke was defined as NIHSS < 4 and modified Rankin Scale (mRS) < 2. Patients were followed for 12 months after the index stroke. The primary endpoints included fatigue and neuropsychiatric impairment, which were evaluated with the Fatigue Severity Scale (FSS) and the Hospital Anxiety Depression Scale (HADS), respectively. RESULTS: A total of sixty patients were followed in our cohort. The mean age was 53.0 (SD 15.0) and 51.7% were male. There were 32 (53.3%) and 25 (41.7%) patients who developed PSF and post-stroke neuropsychiatric symptoms, respectively. The use of antidepressants and statins were associated with post-stroke fatigue, while women and younger patients were more likely to develop neuropsychiatric symptoms after the stroke (p < 0.05). Eighteen (30.0%) patients were diagnosed with both post-stroke fatigue and psychiatric disorders. CONCLUSIONS: Post-stroke fatigue and neuropsychiatric symptoms are prevalent in minor stroke and should be independently addressed as a part of the recovery goal.

Cognitive Impairment in Patients with Ankylosing Spondylitis.

BACKGROUND: Little is known about the potential systemic effects of ankylosing spondylitis (AS) on the nervous system. We designed a study aiming to assess the frequency and clinical predictors of cognitive impairment in AS patients. METHODS: We carried out a cross-sectional case-control study composed of consecutive patients with AS. Trained and blinded interviewers registered clinical-epidemiological data and applied a standardized neurological assessment for each subject of the study. At baseline, functional limitations were characterized using the Health Assessment Questionnaire. Cognitive impairment was evaluated with the Brief Cognitive Screening Battery, the Montreal Cognitive Assessment, and the Clinical Dementia Rating, while neuropsychiatric symptoms were investigated with the Hospital Anxiety and Depression Scale. Healthy controls were matched for age, educational attainment, sex, and comorbidities. We compared the neurological outcomes between case and controls, and we determined the clinical predictors of cognitive decline. RESULTS: We included 40 patients (mean: 49.3 years) with AS and 40 healthy controls (mean: 48.8 years) in our study. In Brief Cognitive Screening Battery, patients with AS presented a statistically significant poor performance in the clock drawing test and in the verbal fluency. The mean Montreal Cognitive Assessment (MoCA) scores were significantly lower in AS subjects compared to the control group. Also, the prevalence of subjects classified as cognitively impaired according to MoCA was significantly higher in the AS group (90.0% vs. 57.5%, p = 0.02). Moreover, neuropsychiatric symptoms were more prevalent in AS patients. Worse functional limitations were associated with poor cognitive performance as well. CONCLUSIONS: Patients with AS might be more vulnerable to cognitive decline.

The influence of statins on the risk of post-stroke epilepsy.

BACKGROUND: Currently, statins are widely used for secondary prevention of stroke due to their pleiotropic neuroprotective effects. Epilepsy is a common complication of cerebrovascular diseases. The purpose of this study was to evaluate the effect of statin therapy on the occurrence of post-stroke epilepsy (PSE). METHODS: In this prospective cohort study, patients who suffered an ischemic stroke and without history of epilepsy before stroke were enrolled. At baseline, patients were classified according to the particularities of statin therapy. Statin use onset and adherence to treatment were registered as well. After a follow-up period of 1 year, we assessed the occurrence of seizures and PSE. RESULTS: Among the 477 patients included in our cohort, there were 91 (19.1%) patients without statins, 160 (33.5%) with simvastatin 20 mg, 180 (37.7%) with simvastatin 40 mg, and 46 (9.6%) with high-potency statins. Overall, PSE emerged in 53 (11.1%) patients. PSE was significantly more prevalent among those who did not receive statins and those with lower doses of simvastatin. Acute onset of statin use was associated with reduced odds of having PSE. CONCLUSION: Adequate treatment with statins after stroke may lower the risk of PSE.

Occupational outcomes of people with multiple sclerosis during the COVID-19 pandemic: a systematic review with meta-analysis.

Background: People with Multiple Sclerosis (PwMS) are vulnerable to unfavorable occupational outcomes and the COVID-19 pandemic brought major consequences on people's professional lives. In this view, we decided to investigate the occupational outcomes of PwMS during the COVID-19 pandemic. Methods: We performed a systematic review with meta-analysis searching key terms in four databases. We initially included any peer-reviewed original article that enrolled adult patients with the diagnosis of MS and assessed any occupational variable during the COVID-19 pandemic. There were no time limits and no language restrictions. The primary outcomes were the prevalence of unemployment, retirement and employment status change among people with MS during the COVID-19 pandemic. Other outcomes included the modality and characteristics of work: type of work, full-time work, part-time work and remote work. We also searched for data from studies that addressed any change in the work status due to the COVID-19 outbreak. Results: We identified 49 eligible articles comprising a total sample size of 17,364 individuals with MS. The pooled prevalence of unemployment and retirement was 0.47 (95% CI = 0.42-0.53). The pooled prevalence of PwMS who were unemployed or retired was positively associated with the progressive phenotype of the disease (p = 0.017) and the use of glatiramer acetate (p = 0.004), but negatively associated with hospitalization due to COVID-19 (p = 0.008) and the use of immunosuppressants (p = 0.032), siponimod (p < 0.001), and cladribine (p = 0.021). The pooled proportion of PwMS that reported any change of the employment status during the COVID-19 pandemic was 0.43 (95% CI = 0.36-0.50) while the pooled prevalence of PwMS who worked remotely during this period was 0.37 (95% CI = 0.15-0.58). The change in employment status was negatively associated with the duration of MS (p = 0.03) but positively associated with the progressive phenotype of the disease (p < 0.001). Conclusion: Our seminal review may serve as an example of how patients with neurological diseases or disabilities in general may have their jobs impacted in a pandemic and foster the context of global socio-economic crisis.

Occupational risk factors for multiple sclerosis: a systematic review with meta-analysis.

Objective: We decided to conduct the first systematic review with meta-analysis to provide the highest level of up-to-date evidence on the occupational risk factors for Multiple Sclerosis. Methods: A systematic, comprehensive literature search was performed in four electronic academic databases. We included any case-control study that enrolled working-age subjects and compared the proportion of MS cases with controls who were not exposed to an occupational risk factor. The primary outcome was the occurrence of MS. The quality assessment was performed with the Critical Appraisal Checklist for Case Control Studies, developed, and validated by the Joanna Briggs Institute. All the selection process was also carried out by two independent and previously trained researchers. Results: Overall, the total sample included 19,004 people with MS and 4,164,162 controls. Agricultural workers (OR = 1.44, 95% CI 1.13-1.83), offshore workers (OR = 3.56, 95% CI 2.74-4.61), and hairdressers (OR = 8.25, 95% CI 1.02-66.52) were associated with a higher probability of being diagnosed with MS. In parallel, workers exposed to toxic fumes from oil wells (OR = 16.80, 95% CI 8.33-33.90), low-frequency magnetic fields (OR = 1.71, 95% CI 1.03-2.72), and pesticides (OR = 3.17, 95% CI = 2.53-3.99) also had an increased likelihood of having MS. Conclusion: Our study has the potential to influence more assertive public policies. Nevertheless, future studies on how the occupational setting may contribute to the incidence of MS are highly recommended. Systematic review registration: The protocol was registered in the international prospective register of systematic reviews (PROSPERO- CRD42023443257).

The prognostic significance of the lipid profile after an ischemic stroke.

BACKGROUND: The role that cholesterol levels play in stroke is still uncertain, especially in secondary prevention. The aim was to determine how a comprehensive analysis of the lipid profile can be associated with post-stroke outcomes.Consecutive patients diagnosed with ischemic stroke were included in our cohort and followed up for 24months. Baseline clinical and demographic data were collected as well as a complete lipid profile 6-months after the index stroke. Lipid variables were analyzed quantitatively and qualitatively. Clinical outcomes included stroke recurrence, major cardiovascular events, and functional performance (assessed with the modified Rankin scale). RESULTS: The study included 588 patients with an average age of 58.3 years. There were 148 (25.2%) patients with high total cholesterol, 260 (44.2%) with low HDL, 180 (30.6%) with high LDL, and 204 (34.7%) with high triglycerides. There were 164 (27.9%) patients with no abnormalities in the lipid profile. After the follow-up, 108 (18.3%) had another stroke, 32 (5.4%) had major cardiovascular events, and 360 (61.2%) presented good functional outcomes. A higher LDL-C/HDL-C ratio and a low HDL-C level were significantly associated with worse cardiovascular outcomes. The detection of LDL-C > 70 mg/dL was an independent predictor of a higher risk of stroke recurrence and worse functional performance. The greater the number of altered lipid variables, the greater the chance of developing an unfavorable composite outcome and presenting cardiovascular events after the stroke. CONCLUSIONS: The complete analysis of the lipid panel allows the determination of the prognosis of patients who suffered a stroke.

Occupational outcomes of people with multiple sclerosis: a scoping review.

OBJECTIVES: To update the knowledge on the occupational outcomes associated with multiple sclerosis (MS), systematically examine the extent, scope and nature of the pre-existing literature and identify research gaps in the existing literature. DESIGN: Scoping review. DATA SOURCES: A comprehensive database search of PubMed/MEDLINE, Scopus, SciVerse ScienceDirect and Web of Science was performed. There were no time limits. ELIGIBILITY CRITERIA: We included any peer-reviewed original article reporting the occupational outcomes of people with MS between the ages of 18 and 65 years. We excluded those off-topic and with insufficient information. METHODS: This review was conducted following the Joanna Briggs Institute recommendations and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for scoping review checklist. Screening, reading of full-texts and data extraction was performed in a standardised way by expert reviewers from 14 July 2021 to 31 October 2021. We provided a narrative synthesis and an overview of findings. RESULTS: The initial systematic search yielded 104 228 results. After removing duplicates and applying the exclusion criteria, 403 articles were included in the review. In total, the studies evaluated 492 062 subjects with MS. One hundred fifty-four (38.2%) articles were published in the last 5 years, mostly from Europe and North America (50.9% and 33.0%, respectively). Concerning the occupational outcomes, studies mostly addressed unemployment (311, 77.2%), early retirement (120, 29.8%), disability pension (117, 29.0%), sick leave (77, 19.1%), the indirect cost of MS (74, 18.4%) and work characteristics (57, 14.1%). The results were categorised into seven subtopics: 'Changes in work and occupational status due to MS', 'work-related socio-economic consequences of MS', 'risk factors for unfavourable occupational outcomes', 'reported barriers to employment', 'reported job accommodations and vocational rehabilitation strategies', 'job satisfaction, stigma, and disclosing the diagnosis in the workplace' and 'rating clinical scales'. CONCLUSIONS: There are several issues that deserve further in-depth study by the scientific community in order to improve the occupational outcomes of people with MS.

Cognitive impairment in patients with psoriatic arthritis.

BACKGROUND: Psoriatic arthritis (PsA) is an inflammatory rheumatic disorder associated with cutaneous psoriasis. Neurological manifestations are not uncommon in rheumatic diseases and recent studies point to a possible underestimation of cognitive impairment in this group of diseases. Our aim was to assess the cognitive impairment in patients with PsA. METHODS: We carried out a cross-sectional case-control study with consecutive patients with PsA. Trained interviewers conducted structured and standardized in-person assessments. At baseline, functional limitations were characterized using the Health Assessment Questionnaire (HAQ). Cognitive function was evaluated with the Montreal Cognitive Assessment (MoCA) and neuropsychiatric symptoms were investigated with the Hospital Anxiety and Depression Scale (HADS). Using a proper statistical analysis, we compared the differences in the neurological outcomes between cases and controls. RESULTS: A total of 37 patients with PsA and 36 healthy controls were included in our study. Patients with PsA had a worse MoCA score when compared to controls (p = 0.01). The proportion of patients with cognitive impairment according to MoCA between cases and controls was also statistically significant (91.9% vs 58.3%, p = 0.002). Executive skills, naming, language, and abstraction were the most affected domains. There was no statistical difference between the prevalence of neuropsychiatric symptoms between the two groups. Patients with increased functional limitations are associated with poor cognitive performance (p < 0.05). CONCLUSION: Cognitive impairment might be a neurological manifestation of PsA.

Stigma, Discrimination and Disclosure of the Diagnosis of Multiple Sclerosis in the Workplace: A Systematic Review.

The objective of the study was to describe and analyze the stigma, discrimination and the disclosure of the diagnosis of Multiple Sclerosis (MS) in the workplace. The protocol was registered in PROSPERO (CRD42022320437). We systematically searched four scientific databases with key search terms. We included any original peer-reviewed articles reporting the stigma or discrimination experienced at work due to MS or the disclosure of the diagnosis of MS in the workplace. No time limits were set for the search. An appraisal of the individual study quality was performed with the JBI critical appraisal checklist. Overall, 26 studies were deemed to fulfil all the eligibility criteria. The total number of participants in this review was 9571. The prevalence of people with MS who experience some degree of stigma in the workplace can be as high as 79.2%. Those who report greater feelings of discrimination are more likely to be unemployed. The prevalence of employers' and co-workers' awareness of the diagnosis varies from 31.7 to 90.2%. The main reason for non-disclosure is the fear of being discriminated against. The psychosocial work environment needs to be taken into consideration as part of public and individual policies to promote the health of patients with MS.

Spatial and temporal distribution of the prevalence of unemployment and early retirement in people with multiple sclerosis: A systematic review with meta-analysis.

BACKGROUND: We aimed to summarise the prevalence of unemployment and early retirement among people with MS and analyze data according to a spatio-temporal perspective. METHODS: We undertook a systematic search of PubMed/MEDLINE, Scopus, SciVerse ScienceDirect, and Web of Science. We included any peer-reviewed original article reporting the prevalence of unemployment and early retirement in the working-age population with MS. We excluded articles off-topic, with other study designs, whose study sample were unlikely to be representative of the MS population and in case of unavailability of the full text or essential information. A random-effects meta-analysis was used to measure overall prevalence estimates of unemployment and early retirement. We used meta-regression and subgroup analysis to evaluate potential moderators of prevalence estimates and the leave-one-out method for sensitivity analyses. RESULTS: Our research identified 153 studies across 29 countries encompassing 188436 subjects with MS. The pooled overall effect size for unemployment and early retirement was 35.6% (95% CI 32.8-38.4; I2 = 99.31) and 17.2% (95% CI 14.6-20.2; I2 = 99.13), respectively. The prevalence of unemployment varied according to the year of publication (p < 0.001) and there was a statistically significant decrease in the prevalence of unemployment over time (p = 0.042). Regarding early retirement, only seven (31.8%) estimates obtained from studies that were published before 2010 were below the overall effect size in comparison to 27 (60.0%) estimates extracted from data published between 2010 and 2021 (p = 0.039). There was a significant difference in prevalence according to countries (p < 0.001). Psychiatric illness was an important clinical feature responsible for patients leaving the workforce in regions with a high MS prevalence. CONCLUSIONS: Unemployment and early retirement due to MS remain highly prevalent, despite a slight decline in the last decade. The prevalence of unemployment and early retirement varies globally.

The COVID-19 Pandemic Sacrificed the Excellence of Stroke Care Worldwide.

The COVID-19 pandemic has had not only a tremendous impact on public health but also on the care of many pre-COVID-19 diseases, such as stroke. The pandemic has tested the robustness of comprehensive stroke care programs. Especially during the months of confinement, an alarming increase in the incidence of several risk factors for cerebrovascular diseases was noticed, without, however, the proportional strengthening of strategies for the prevention and/or control of comorbidities. Patients who had already suffered a stroke were neglected from the secondary prevention routine and neurological rehabilitation therapies. Regarding the acute treatment, the fear of contagion in the hospital environment promoted a significant delay in the time from the onset of symptoms to admission to an emergency department as well as in the door to imaging and door to needle times. Moreover, the pandemic also exposed the enormous inequalities in the approach to cerebrovascular diseases worldwide. Actually, many consequences of COVID-19 in stroke care will persist for months even after pandemic control. Strategies to combat the pandemic must be reconciled with the fight against stroke in a way that does not exclude any patient from access to the best possible care.

Effectiveness of statins in patients with stroke due to cervical artery dissection: A preliminary study.

BACKGROUND: Statin therapy has become one of the most important advances in stroke secondary prevention. Nevertheless, statin therapy in patients who present an ischemic stroke following cervical artery dissection (CAD) has not yet been supported by clinical evidence. This study aimed to investigate the effect of statins on neurological outcomes after a stroke due to CAD. METHODS: We conducted a prospective cohort study including consecutive patients diagnosed with a stroke due to CAD. Subjects were classified into non-statin, simvastatin 20mg, simvastatin 40mg, and high-potency statin groups. After 2 years, the functional outcome, stroke recurrence, major cardiovascular events, and mortality were assessed. RESULTS: Among the 54 patients included in our cohort, there were 16 (29.6%) patients without statins, 22 (40.7%) with simvastatin 20mg, 12 (22.2%) with simvastatin 40mg and 4 (7.5%) with high-potency statins. Using simvastatin 40mg was associated with a significantly lower incidence of stroke recurrence. Patients with simvastatin 40mg and high-potency statins presented the best functional recovery throughout the follow-up (p<.01). DISCUSSION: The use of statins in patients with CAD-related stroke may improve functional outcomes in specific cases. Statins do not prevent stroke recurrence and major cardiovascular events in this type of stroke.

Post-stroke aphasia in famous writers: when Neurology left geniuses speechless.

Aphasia is a frequent and devastating stroke complication that does not spare even great writers. In these cases, not only one of the highest cognitive functions is suddenly lost but also the act of bringing beauty into the world. Herein, we discuss the case of three writers who had to abandon their art compulsorily due to a cerebrovascular disease: Charles Baudelaire, Ralph Waldo Emerson, and Stendhal. They were magnificent writers, united by excellence in literature and an inevitable destiny that restricted their art to just a few words. They are also examples of the proximity of Neurology to Art, History, and Literature.

Parsonage-Turner syndrome following coronavirus disease 2019 immunization with ChAdOx1-S vaccine: a case report and review of the literature.

BACKGROUND: Parsonage-Turner syndrome is an acute peripheral neuropathy that affects the upper brachial plexus region. Previously published reports demonstrate that the condition can be triggered by surgery, infection, autoimmune diseases, strenuous exercise, trauma, radiation, and vaccination. Parsonage-Turner syndrome has already been reported in three other patients who were vaccinated against coronavirus disease 2019. CASE PRESENTATION: We report the case of a 51-year-old Caucasian man without comorbidities who received the first dose of the ChAdOx1-S recombinant vaccine (Vaxzevria, AstraZeneca, Oxford, UK) against coronavirus disease 2019 and was diagnosed with Parsonage-Turner syndrome. A few days after getting vaccinated, the patient reported a progressive increase in pain in the region of vaccine administration. One month later, the shoulder pain was followed by symptoms of hypoesthesia and muscle weakness on abduction and elevation of the left upper limb. Neurological examination revealed an atrophy of the proximal muscles of the left upper limb, accompanied by paresis of the left deltoid, biceps brachii, triceps brachii, and infraspinatus muscles. Electroneuromyography carried out 3 months after the onset of symptoms showed signs consistent with brachial plexus neuritis. The adverse reaction has been properly reported to the Italian Pharmacovigilance System (Italian Medicines Agency-Agenzia Italiana del Farmaco. CONCLUSION: The increased awareness of such association is essential for early identification and diagnosis and, thus, better clinical outcomes.
