BACKGROUND: Prevalence of atrial fibrillation (AF) is increasing globally, and the fivefold increase in stroke risk constitutes significant healthcare burden. AIMS: We aim to evaluate the trends of AF-related stroke and transient ischaemic attack (AF-stroke/TIA), prior anticoagulant use and their risk factors in different age groups in Chinese population. METHODS: Data were retrieved from the stroke registry at Prince of Wales Hospital. We compared the data at 5-year intervals over a 15-year period (years 1999, 2004, 2009 and 2014)...

BACKGROUND AND PURPOSE: The role of stress-related endocrine dysregulation in the development of cognitive changes following a stroke needs further elucidation. We explored this issue in a longitudinal study on stroke survivors using hair cortisol concentrations (HCC), a measure of integrated long-term cortisol levels. METHODS: Participants were consecutive cognitively intact first-ever mild-moderate ischemic stroke/transient ischemic attack (TIA) survivors from the Tel Aviv Brain Acute Stroke Cohort (TABASCO) study...

BACKGROUND: Several studies have explored cervical kyphosis (CK) in adolescent idiopathic scoliosis (AIS) patients. However, few studies have evaluated the cervical alignment in these patients according to their coronal curve type. The aim of this study was to analyze the radiological features of cervical sagittal alignment in Lenke 1 AIS patients before and after surgery. METHODS: This is a retrospective study enrolled 50 patients. Preoperative and postoperative standing full-length radiographs (at last follow-up after operation) were used to measure the coronal and sagittal parameters...

OBJECTIVE: Subclinical hypothyroidism (SCH) has been associated with atherosclerosis and increased risk of ischemic stroke. However, whether SCH is associated with cerebral small vessel disease (cSVD) remains largely unexplored. This study aimed to investigate the relationship between SCH and total cSVD burden, a composite measurement detected with magnetic resonance imaging (MRI), in patients with minor ischemic stroke or transient ischemic attack (TIA). DESIGN: This was a prospective observational cohort study conducted in a tertiary referral hospital...

OBJECTIVE: Therapeutic options for ischaemic stroke, such as thrombolysis or thrombectomy, are time sensitive. Multiple innovations have been established to reduce the symptom-to-needle time. One such innovation is the prealerting of emergency department (ED) or stroke unit staff by prehospital personnel of suspected stroke patients. The diagnosis of stroke can sometimes be difficult, with stroke mimics being a recognized issue. The prealert mobilizes ED, stroke and imaging personnel, which, for a true-positive, improves door-to-needle times...

INTRODUCTION: There are no obvious guidelines for therapy of elevated blood pressure (BP) in the emergency department (ED). Diastolic BP is probably more difficult to control compared with systolic BP. AIM: To characterize patients who respond with a significant decrease in diastolic BP in the ED, whether treated or not. METHODS: In this retrospective cohort study, all patients attending a tertiary care ED with elevated BP were evaluated. Clinical characteristics of patients in whom diastolic BP decreased ≥20% were compared with those in whom diastolic BP decreased <20%...

BACKGROUND AND PURPOSE: We aimed to investigate the optimal timing of diffusion-weighted imaging (DWI) in patients with transient ischemic attack (TIA). METHODS: Seventy-three consecutive patients with TIA underwent DWI on admission (initial DWI) and at 24 hours after admission (second DWI). Patients were divided into 2 groups based on initial DWI findings in relation to the second examination: false negative (group 1) and other (group 2). The probability of initial false-negative findings was determined for each hour from TIA onset to initial DWI...

Families living in poverty are significantly more likely to become involved with child welfare services, and consequently, referred to interventions that target abusive and neglectful parenting practices. Program engagement and retention are difficult to achieve, possibly because of the concrete resource insufficiencies that may have contributed to a family's involvement with services in the first place. Various strategies have been used to enhance program completion, such as motivational interventions, monetary incentives, and financial assistance with concrete needs...

Premature atrial complexes (PACs) have been proposed as a possible mediator between normal sinus rhythm and atrial fibrillation (AF). The aim of this study was to summarize the available knowledge of association between PACs and recurrent stroke or transient ischemic attack (TIA) in ischemic stroke patients. Areas covered: In this systematic review, we investigated the risk of recurrent events in patients who experienced ischemic stroke or TIA. Occurrence of PACs in electrocardiographic monitoring after index stroke/TIA was required...

INTRODUCTION: An ischemic stroke is an event that occurs due to cerebral vascular disease and is directly related to the degree of vascular damage. This process is associated with atherosclerosis progression and is influenced by the presence of cardiovascular risk factors. AIMS: One of the goals of our research was to examine whether specific medications used for treating hypertension are associated with the development of strokes. METHODS: In a retrospective study of patients who were hospitalized between the years 2003-2008 due to a cerebrovascular accident (CVA) or a transient ischemic attack (TIA), 916 cases of stroke patients were reviewed...

BACKGROUND: Scarce data comparing real-world outcomes between apixaban and vitamin K antagonist (VKA) users with nonvalvular atrial fibrillation (NVAF) are available. We sought to assess the effectiveness and safety of newly-initiated apixaban vs. VKA in German NVAF patients. MATERIALS AND METHODS: We performed a retrospective analysis in German outpatients using IMS Disease Analyzer data. Adults newly-initiated on apixaban or a VKA from January 2013 to March 2015 with a diagnosis of NVAF on the day of the first qualifying oral anticoagulant (OAC) prescription (index date) or any time during one year prior, and at least one year of follow-up were included...

If oil sands process-affected water (OSPW) is to be returned to the environment, a desire is that it not adversely affect aquatic life. We investigated whether a relevant model fish (rainbow trout; Oncorhynchus mykiss) could detect OSPW using its olfactory sense (smell), and whether exposure to it would result in behavioural changes. We also investigated whether ozonation of OSPW, which lowers the concentration of organic compounds attributed with toxicity (naphthenic acids), would ameliorate any observed adverse effects...

OBJECTIVES: Migraine is a suggested risk factor for aneurysmal subarachnoid hemorrhage (aSAH). An increased risk of aSAH in migraineurs may be explained by an increased prevalence of unruptured intracranial aneurysms (UIA). We performed a case-control study to compare lifetime migraine prevalence in patients with UIA, patients with a history of transient ischemic attact (TIA) or ischemic stroke and controls without a history of aSAH, TIA or ischemic stroke. MATERIALS AND METHODS: Patients with UIA were recruited from two university hospitals...

BACKGROUND: Evidence of a decline in the incidence of stroke has emerged from population-based studies. These have included retrospective and prospective cohorts. However, in Australia and other countries, government bodies and stroke foundations predict a rise in the prevalence of stroke that is anticipated to increase the burden of stroke across the entire domain of care. This increase in prevalence must be viewed as different from the decline in incidence being observed, a measure of new stroke cases...

Differences in the management of atrial fibrillation (AF) between men and women were investigated by using Gulf SAFE data in the Middle East. The study included 2,043 patients presenting with AF to emergency room (ER) were prospectively enrolled and followed for one-year. Women were older, have higher body mass index (BMI), comorbidities, and health complications than men. With regard to management of AF, cardioversion was recommended more often for men (16.7% vs. 9.3%), and underwent electrical cardioversion (2...

Squaraine rotaxanes are mechanically interlocked molecules comprised of a dumbbell shaped squaraine dye inside a tetralactam macrocycle. Previous squaraine rotaxanes have employed planar squaraine dyes with 4-aminophenyl, 2-aminothiophene or N-amino units appended to the central C4O2 core. Here we describe two rotaxanes that encapsulate a 3,3-dimethylindoline squaraine inside a tetralactam with anthracene sidewalls. The rotaxanes were prepared by a templated clipping reaction and an X-ray crystal structure shows that the squaraine gem-dimethyl groups force a relatively wide separation between the macrocycle anthracene sidewalls...

OBJECTIVE: In patients with TIA and ischemic stroke, we validated the total small vessel disease (SVD) score by determining its prognostic value for recurrent stroke. METHODS: Two independent prospective studies were conducted, one comprising predominantly Caucasian patients with TIA/ischemic stroke (Oxford Vascular Study [OXVASC]) and one predominantly Chinese patients with ischemic stroke (University of Hong Kong [HKU]). Cerebral MRI was performed and assessed for lacunes, microbleeds, white matter hyperintensities (WMH), and perivascular spaces (PVS)...
