Vascular contributions to cognitive impairment and dementia (VCID) is understood to be the second most common cause of dementia after Alzheimer's disease (AD), and is also a frequent co-morbidity with AD. While VCID is widely acknowledged as a key contributor to dementia, the mechanistic underpinnings of VCID remain poorly understood. In this review, we address the potential role of astrocytes in the pathophysiology of VCID. The vast majority of the blood vessels in the brain are surrounded by astrocytic end-feet...

Importance: The androgen receptor inhibitor enzalutamide prolongs survival in men with metastatic castration-resistant prostate cancer (mCRPC). In controlled clinical studies, 0.5% (10 of 2051) of patients experienced seizure, but patients with a history of or risk factors for seizure were excluded. Men with mCRPC and seizure risk factors have an estimated seizure rate of 2.8 per 100 patient-years without enzalutamide exposure. Objective: To assess seizure incidence in patients with seizure risk factors who were receiving enzalutamide for mCRPC...

INTRODUCTION: Advances in modern medicine have led to people living longer and healthier lives. Frailty is an emerging concept in medicine yet to be explored as a risk factor in cardiac surgery. When it comes to CABG surgery, randomized controlled clinical trials have primarily focused on low-risk (ROOBY, CORONARY), elevated-risk (GOPCABE) or high-risk patients (BBS), but not on frail patients. Therefore, we believe that off-pump CABG could be an important technique in patients with limited functional capacity to respond to surgical stress...

Introduction: Atherosclerosis is considered the pathophysiology underlying cardiovascular (CVD), cerebrovascular, and peripheral vascular diseases. Evidence supporting an autoimmune component is emerging, with imaging studies correlating MYC-associated zinc finger protein antibody (MAZ-Ab) optical density (OD) with plaque activity. This study compares MAZ-Ab OD on ELISA testing among patients presenting with acute coronary syndromes (ACSs) to healthy controls and investigates the association of MAZ-Ab to traditional CVD risk factors...

REVIEW
Eugene Han, Yong Ho Lee
As the number of individuals with non-alcoholic fatty liver disease (NAFLD) has increased, the influence of NAFLD on other metabolic diseases has been highlighted. Accumulating epidemiologic evidence indicates that NAFLD not only affects the liver but also increases the risk of extra-hepatic diseases such as type 2 diabetes mellitus, metabolic syndrome, dyslipidemia, hypertension, cardiovascular or cerebrovascular diseases, and chronic kidney disease. Non-alcoholic steatohepatitis, an advanced type of NAFLD, can aggravate these inter-organ relationships and lead to poorer outcomes...

BACKGROUND: Over 150 000 cases of suspected transient ischaemic attack (TIA) are referred to outpatient clinics in England each year. The majority of referrals are made by GPs. AIM: This study aimed to identify how many patients referred to a TIA clinic actually have TIA (that is, calculate the positive predictive value [PPV] of first-contact healthcare referral) and to record the alternative diagnoses in patients without TIA, in order to determine the optimal service model for patients with suspected TIA...

BACKGROUND: We aimed to evaluate the epidemiological features of transient ischemic attack (TIA). METHODS: All TIAs were prospectively collected in Dijon, France, using a population-based registry (2013-2015). TIAs were considered the first-ever in patients who had no previous cerebrovascular events (CVEs); otherwise they were considered recurrent TIAs. Annual incidence (first-ever TIAs) and attack rates (first-ever and recurrent TIAs) were calculated. RESULTS: Four hundred twenty TIAs were registered (255 first-ever and 165 recurrent TIAs, mean age: 74...

Aneurysmal subarachnoid hemorrhage (SAH) is a devastating cerebral event that kills or debilitates the majority of those afflicted. The blood that spills into the subarachnoid space stimulates profound cerebral artery vasoconstriction and consequently, cerebral ischemia. Thus, once the initial bleeding in SAH is appropriately managed, the clinical focus shifts to maintaining/improving cerebral perfusion. However, current therapeutic interventions largely fail to improve clinical outcome, because they do not effectively restore normal cerebral artery function...

BACKGROUND: An ambulance equipped with a computed tomography (CT) scanner, a point-of-care laboratory, and telemedicine capabilities (mobile stroke unit [MSU]) has been shown to enable the delivery of thrombolysis to stroke patients directly at the emergency site, thereby significantly decreasing time to treatment. However, work-up in an MSU that includes CT angiography (CTA) may also potentially facilitate triage of patients directly to the appropriate target hospital and specialized treatment, according to their individual vascular pathology...

Subarachnoid hemorrhage (SAH) is a neurologic emergency associated with high mortality rate. Polymorphic ventricular tachycardia (VT) is a rare arrhythmia. It can occur in any setting of a long QT interval and bradycardia. This may result from a cardiomyopathy (both ischemic and non-ischemic), acute coronary ischemia, congenital long QT syndrome, electrolyte disturbances and cerebrovascular diseases. We report a rare case of polymorphic VT of unclear etiology with a normal corrected QT, likely secondary to SAH...

BACKGROUND: Invasive off- or on-pump cardiac surgery (elective and emergency procedures, excluding transplants are routinely performed to treat complications of ischaemic heart disease. Randomised controlled trials (RCT) evaluate the effectiveness of treatments in the setting of cardiac surgery. However, the impact of RCTs is weakened by heterogeneity in outcome measuring and reporting, which hinders comparison across trials. Core outcome sets (COS, a set of outcomes that should be measured and reported, as a minimum, in clinical trials for a specific clinical field) help reduce this problem...

PURPOSE OF REVIEW: We review recent MRI research that addresses two important challenges in cerebral small vessel disease (SVD) research: early diagnosis, and linking SVD with cognitive impairment. First, we review studies of MRI measurements of blood flow and blood-brain barrier integrity. Second, we review MRI studies identifying neuroimaging correlates of SVD-related cognitive dysfunction, focusing on brain connectivity and white matter microarchitecture. This research is placed in context through discussion of recent recommendations for management of incidentally discovered SVD, and neuroimaging biomarker use in clinical trials...

PURPOSE OF REVIEW: Stents and flow diverters have revolutionized the treatment of cerebrovascular disease. Guglielmi coils, flexible microcatheters, and first-generation intracranial stents, such as Neuroform (Stryker Neurovascular) and Enterprise stents (Codman/DePuy-Synthes), have paved the way for the development of the Pipeline Embolization Device (PED) (ev3/Covidien/Medtronic) and other endovascular approaches. RECENT FINDINGS: This review discusses the historical development of flow diverter technologies from the PED to similar devices, such as the Surpass stent (Stryker Neurovascular), the Flow-Redirection Endoluminal Device (FRED; MicroVention, Inc...

RATIONALE: Abdominal apoplexy is a rare and fatal emergency event, which is coined as a comparison to the cerebrovascular apoplexy. The exact mechanism of abdominal apoplexy was unclear, but arteriosclerosis, hypertension, abdominal aneurysm, and other predisposing angiopathy were considered to be the main reasons of abdominal apoplexy. The development of the imaging technology gave us more opportunities to confirm the diagnosis of abdominal apoplexy. However, the diagnosis and identification of the bleeding sites still continued to be a challenge...

PURPOSE OF REVIEW: Stroke is common and often presents as a neurologic emergency that requires rapid evaluation and treatment to minimize debilitation. Recent advances in therapy expanded time windows for intra-arterial thrombectomy in ischemic stroke, and surgical interventions for clot evacuation in large intracranial hemorrhage have recently proven feasible. This review discusses recent data regarding new therapeutic options in both ischemic and hemorrhagic stroke, notably in scenarios in which therapy was previously limited to supportive care...
