Association of intracranial large artery disease with long-term prognosis after ischaemic stroke.

Introduction: Intracranial large artery disease (ICLAD) is a common cause of ischaemic stroke and is associated with the risk of recurrent vascular events in the short term. We compared the incidence of various long-term vascular outcomes between ischaemic stroke patients with and without ICLAD.

Methods: This was a longitudinal observational study of acute ischaemic stroke patients who were followed up serially for recurrent stroke, myocardial infarction or vascular death up to a median of 86 months.

Associated demographic factors for the recurrence and prognosis of stroke patients within a multiethnic Asian population.

Objective: There is a paucity of studies investigating the outcomes among Asian stroke patients. Identifying subgroups of stroke patients at risk of poorer outcomes could identify patients who would benefit from targeted interventions. Therefore, the aim of this study was to identify which ischemic stroke patients at high risk of recurrent events and mortality.

Neurophysiological findings in conus medullaris infarction-a case report and systematic review of the literature.

Introduction: Conus medullaris infarction (CMI) is a rare vascular phenomenon that has been scarcely reported in the literature. While previous studies have described the clinical and radiological features of CMI, little attention has been paid to its associated neurophysiological findings.

Methods: We present a case of idiopathic CMI and its neurophysiological findings, then present our findings from a systematic review of other reports of CMI with neurophysiological features found via PubMed search.

Predictors of post stroke cognitive impairment: VITATOPS cognition substudy.

Introduction: Post stroke cognitive impairment (PSCI) is a common complication of ischemic stroke. PSCI can involve different depending on clinical and stroke related characteristics. The aim of this study is to determine the factors associated with impairments in specific cognitive domains.

Cluster analysis and visualisation of electronic health records data to identify undiagnosed patients with rare genetic diseases.

Rare genetic diseases affect 5-8% of the population but are often undiagnosed or misdiagnosed. Electronic health records (EHR) contain large amounts of data, which provide opportunities for analysing and mining. Data mining, in the form of cluster analysis and visualisation, was performed on a database containing deidentified health records of 1.

Recurrent vascular events partially explain association between diabetes and poor prognosis in young ischemic stroke patients.

Background And Aims: Stroke is the second leading cause of death and third leading cause of disability worldwide. There is an increasing incidence of stroke among the young. In this study, we aimed to identify factors associated with poor long-term prognosis in young stroke patients.

Adherence to secondary stroke prevention medications in Singapore: a single center study.

Objectives: Recurrent strokes are associated with greater disability and mortality than first-time strokes. However, adherence to secondary stroke prevention medications has been reported to be suboptimal. We assessed medication adherence to antihypertensives, antiplatelets, and statins after acute ischemic stroke and identified factors associated with non-adherence behavior to each drug class.

Genetic and Nongenetic Components of Stroke Family History: A Population Study of Adopted and Nonadopted Individuals.

Background Genetic and nongenetic factors account for the association of family history with disease risk. Comparing adopted and nonadopted individuals provides an opportunity to disentangle those factors. Methods and Results We examined associations between family history of stroke and heart disease with incident stroke and myocardial infarction (MI) in 495 640 UK Biobank participants (mean age, 56.

Non-Hypertensives and Those with Normal Cholesterol Are More Likely to Have Concomitant Cancer amongst Patients with Ischemic Stroke: A Retrospective Cross-Sectional Registry-Based Study.

Introduction: Patients with cancer are known to have an increased risk of ischemic stroke (IS) around the time of their diagnosis. However, there is a paucity of data in Asian populations, and as such, we aimed to determine cancer incidence rates and patterns in Asian IS patients as well as investigate the differences in vascular risk profile of IS patients with and without concomitant cancer.

Methods: We conducted a retrospective cross-sectional study using data from the Singapore Stroke and Cancer registries.

Empiric treatment with aspirin and ticagrelor is the most cost-effective strategy in patients with minor stroke or transient ischemic attack.

Background: Patients with minor ischemic stroke or transient ischemic attacks (TIAs) are often treated with dual antiplatelet therapy regimens as part of secondary stroke prevention. Clopidogrel, an antiplatelet used in these regimens, is metabolized into its active form by the enzyme. Patients with loss of function (LOF) mutations in are at risk for poorer secondary outcomes when prescribed clopidogrel.

Genetic variation supports a causal role for valproate in prevention of ischemic stroke.

Background: Valproate is a candidate for ischemic stroke prevention due to its anti-atherosclerotic effects in vivo. Although valproate use is associated with decreased ischemic stroke risk in observational studies, confounding by indication precludes causal conclusions.

Aims: We applied Mendelian randomization to determine whether genetic variants that influence seizure response among valproate users associate with ischemic stroke.

Genetic and non-genetic components of family history of stroke and heart disease: a population-based study among adopted and non-adopted individuals.

Background: It is increasingly clear that genetic and non-genetic factors account for the association of family history with disease risk in offspring. We sought to distinguish the genetic and non-genetic contributions of family history of stroke and heart disease on incident events by examining adopted and non-adopted individuals.

Methods: We examined associations between family history of stroke and heart disease with incident stroke and myocardial infarction (MI) in 495,640 participants of the UK Biobank (mean age 56.

Anti-NMDAR encephalitis in Southeast Asia - A single-centre, longitudinal study.

Aims: To describe the clinical features and outcomes of anti-NMDA receptor encephalitis (ANMDARE) in Southeast Asian (SEA) patients.

Method: SEA patients diagnosed and treated for ANMDARE at Singapore General Hospital between January 2010 and June 2020 were included in this observational study, in which their clinical features and outcomes were retrospectively analysed.

Results: We studied 20 patients: 11 Chinese, 3 Tagalogs, 2 Malays, 2 Indians, 1 Eurasian and 1 Javanese.

Social Determinants of Health and Cerebral Small Vessel Disease: Is Epigenetics a Key Mediator?

Cerebral small vessel disease is highly prevalent, particularly in marginalized communities, and its incidence is expected to increase given the aging global population. Cerebral small vessel disease contributes to risk for stroke, vascular cognitive impairment and dementia, late-life depression, and gait disorders. A growing body of evidence suggests that adverse outcomes, including cerebral small vessel disease, caused by traditional cardiovascular risk factors are at least partly mediated by epigenetic changes, some of them already beginning during fetal development.

Genetic variation supports a causal role for valproate in prevention of ischemic stroke.

Valproate is a candidate for ischemic stroke prevention due to its anti-atherosclerotic effects in vivo. Although valproate use is associated with decreased ischemic stroke risk in observational studies, confounding by indication precludes causal conclusions. To overcome this limitation, we applied Mendelian randomization to determine whether genetic variants that influence seizure response among valproate users associate with ischemic stroke.

Neuronal intranuclear inclusion disease.

Neuronal intranuclear inclusion disease is a rare genetic condition, previously diagnosed only at postmortem, but its characteristic radiological features now allow its diagnosis in life. The clinical presentation is variable and we hope this case report will raise awareness of this condition.

C9orf72 expansions are the most common cause of genetic frontotemporal dementia in a Southeast Asian cohort.

Objective: Frontotemporal dementia (FTD) encompasses a spectrum of neurodegenerative disorders, including behavioural variant FTD (bvFTD), semantic variant primary progressive aphasia (svPPA) and non-fluent variant PPA (nfvPPA). While a strong genetic component is implicated in FTD, genetic FTD in Asia is less frequently reported. We aimed to investigate the frequency of Southeast Asian FTD patients harbouring known genetic FTD variants.

B-vitamin supplementation on mitigating post-stroke cognition and neuropsychiatric sequelae: A randomized controlled trial.

Background And Purpose: A third of stroke patients suffer from post-stroke cognitive decline, depressive symptoms, and anxiety symptoms. B-vitamin supplementation provides a possible safe and affordable treatment to mitigate post-stroke neuropsychiatric sequelae via reducing homocysteine levels. Our study aims to examine the effect of B-vitamin supplementation in the prevention of post-stroke cognitive decline, depressive symptoms, and anxiety symptoms.

Long-Term Post-Stroke Functional Outcomes: A Comparison of Diabetics and Nondiabetics.

Introduction: Diabetes mellitus (DM) is known to influence outcomes in the short term following stroke. However, the impact of DM on long-term functional outcomes after stroke is unclear. We compared functional outcomes periodically over 7 years between diabetic and nondiabetic ischemic stroke patients, and investigated the impact of DM on the long-term trajectory of post-stroke functional outcomes.

Cerebellar Stroke in a COVID-19 Infected Patient. a Case Report.

Background: Recent studies have reported that COVID-19 infected patients with stroke, who were often in the older age group, had a higher incidence of vascular risk factors, and more severe infection related respiratory symptoms. These observations provided little evidence to suggest that COVID-19 infection is a potential causative factor for stroke. This report describes a young patient with a cerebellar stroke secondary to COVID-19 infection.

Impact of beliefs about medication on the relationship between trust in physician with medication adherence after stroke.

Objective: To investigate the relationship between medication adherence, trust in physician and beliefs about medication among stroke survivors. To determine whether beliefs about medication would mediate the relationship between trust in physician and medication adherence.

Methods: A sample of 200 patients with a diagnosis of ischemic stroke or transient ischemic attack (TIA) completed a one-time survey, including the shortened Medication Adherence Report Scale (MARS-5), Beliefs about Medicines Questionnaire (BMQ), and Trust in Physician Scale (TIPS).
