AIM: The aim of this study is to examine temporal trends in the use oral anticoagulants (OAC) as stroke prophylaxis in patients with atrial fibrillation (AF) and to examine factors associated with OAC initiation. METHODS AND RESULTS: From Danish nationwide registries, we identified patients diagnosed with AF at Danish hospitals and outpatient clinics between January 2005 and June 2015. OAC initiation was assessed from prescription fills ±180 days from date of AF diagnosis...

Astrocytes play a pivotal role in neuronal survival under the condition of post-ischemic brain inflammation, but the relevant astrocyte-derived mediators of ischemic brain injury remain to be defined. IL-15 supports survival of multiple lymphocyte lineages in the peripheral immune system, but the role of IL-15 in inflammatory disease of the central nervous system is not well defined. Recent research has shown an increase of IL-15-expressing astrocytes in the ischemic brain. Since astrocytes promote neuron survival under cerebral ischemia by buffering excess extracellular glutamate and producing growth factors, recovery of astrocyte function could be of benefit for stroke therapy...

BACKGROUND: Ischemic stroke causes a strong inflammatory response that includes T cells, monocytes/macrophages, and neutrophils. Interaction of these immune cells with platelets and endothelial cells facilitates microvascular dysfunction and leads to secondary infarct growth. We recently showed that blocking of platelet glycoprotein (GP) receptor Ib improves stroke outcome without increasing the risk of intracerebral hemorrhage. Until now, it has been unclear whether GPIb only mediates thrombus formation or also contributes to the pathophysiology of local inflammation...

AIMS: Dipeptidyl peptidase-4 inhibitors (DPP4i) are suggested as 2(nd) and 3(rd) add-on antidiabetic treatment for type 2 diabetes. Previous studies only assessed cardiovascular effects of DPP4i as 2(nd) line treatment, included sulfonylurea as only one comparator, and yielded inconclusive results on the risk of heart failure. This study therefore evaluated comparative cardiovascular risks of DPP4i with other 2(nd) and 3(rd) line antidiabetic drugs. METHODS: Based on a large nation-wide diabetic cohort, 113,051 patients with type 2 diabetes newly on metformin-based dual or triple therapy were identified in 2009-2011 and followed until death or 2013...

BACKGROUND: The objective of this study was to analyse the Neurothrombectomy Network registry of the Neuromed Campus (NMC) of the Kepler University Hospital in Linz (Austria). The data were compared to the results of recently published thrombectomy trials (MR CLEAN, ESCAPE, EXTEND-IA, SWIFT-PRIME, REVASCAT and THRACE). METHODS: We retrospectively studied 246 patients with acute ischemic stroke who underwent thrombectomy between January 2012 and December 2015 at the NMC in Upper Austria...

BACKGROUND: Visuospatial neglect (VSN) is devastating and common after stroke, and is thought to involve functional disturbance of the attention network. Non-invasive theta-burst stimulation (TBS) may help restore the normal function of attention network, therefore facilitating recovery from VSN. OBJECTIVE: This study investigated the effects of continuous TBS on resting-state functional connectivity (RSFC) in the attention network, and behavioral performances of patients with VSN after stroke...

BACKGROUND: Beta-blockers refer to a mixed group of drugs with diverse pharmacodynamic and pharmacokinetic properties. They have shown long-term beneficial effects on mortality and cardiovascular disease (CVD) when used in people with heart failure or acute myocardial infarction. Beta-blockers were thought to have similar beneficial effects when used as first-line therapy for hypertension. However, the benefit of beta-blockers as first-line therapy for hypertension without compelling indications is controversial...

Atrial fibrillation is the most prevalent cardiac arrhythmia, affecting 10% of those aged over 80 years. Despite multiple treatment options, it remains an independent prognostic marker of mortality due to its association with clinical sequelae, particularly cerebrovascular events. Management can be broadly divided into treatment of the arrhythmia, via rhythm or rate control, and stroke thromboprophylaxis via anticoagulation. Traditional options for pharmacotherapy include negatively chronotropic drugs such as β-blockers, and/or arrhythmia-modifying drugs such as amiodarone...

Annually, there are over 2 million incidents of traumatic brain injury (TBI) and treatment options are non-existent. While many TBI studies have focused on the brain, peripheral contributions involving the digestive and immune systems are emerging as factors involved in the various symptomology associated with TBI. We hypothesized that TBI would alter hepatic function, including bile acid system machinery in the liver and brain. The results show activation of the hepatic acute phase response by 2 hours after TBI, hepatic inflammation by 6 hours after TBI and a decrease in hepatic transcription factors, Gli 1, Gli 2, Gli 3 at 2 and 24 hrs after TBI...

Diuretics have been used for years to treat hypertension as both a monotherapy and in combination. Hydrochlorothiazide, indapamide, and chlorthalidone have frequently been considered in the same category as thiazide diuretics, but there is no evidence that their activities are similar. Studies have shown that chlorthalidone and indapamide reduce cardiovascular morbidity and mortality; however, there is no study indicating that hydrochlorothiazide has beneficial effects on cardiovascular outcomes such as myocardial infarction, renal failure, stroke, or death...

BACKGROUND: Sickle cell disease is a genetic chronic haemolytic and pro-inflammatory disorder. The clinical manifestations of sickle cell disease result from the presence of mutations on the beta globin genes that generate an abnormal haemoglobin product (called haemoglobin S) within the red blood cell. Sickle cell disease can lead to many complications such as acute chest syndrome, stroke, acute and chronic bone complications (including painful vaso-occlusive crisis, osteomyelitis, osteonecrosis and osteoporosis)...

If the control of infectious diseases was the public health success story of the first half of the 20th century, then the decline in mortality from coronary heart disease and stroke has been the success story of the century's past 4 decades. The early phase of this decline in coronary heart disease and stroke was unexpected and controversial when first reported in the mid-1970s, having followed 60 years of gradual increase as the US population aged. However, in 1978, the participants in a conference convened by the National Heart, Lung, and Blood Institute concluded that a significant recent downtick in coronary heart disease and stroke mortality rates had definitely occurred, at least in the US Since 1978, a sharp decline in mortality rates from coronary heart disease and stroke has become unmistakable throughout the industrialized world, with age-adjusted mortality rates having declined to about one third of their 1960s baseline by 2000...

BACKGROUND: Acquired brain injury (ABI) can result in impairments in motor function, language, cognition, and sensory processing, and in emotional disturbances, which can severely reduce a survivor's quality of life. Music interventions have been used in rehabilitation to stimulate brain functions involved in movement, cognition, speech, emotions, and sensory perceptions. An update of the systematic review published in 2010 was needed to gauge the efficacy of music interventions in rehabilitation for people with ABI...

Several cell therapies have been explored as novel therapeutic strategies for neonatal encephalopathy because the benefits of current treatments are limited. We previously reported that intravenous administration of human umbilical cord blood (hUCB) CD34+ cells (hematopoietic stem cells/endothelial progenitor cells) at 48 h after insult exerts therapeutic effects in neonatal mice with stroke, i.e., permanent middle cerebral artery occlusion. Although neonatal stroke and hypoxic-ischemic encephalopathy (HIE) are grouped under the term "neonatal encephalopathy," their pathogenesis differs...

Prompt reperfusion after cerebral ischemia is critical for neuronal survival. Any strategies that extend the limited reperfusion window will be of great importance. Acidic postconditioning (APC) is a mild acidosis treatment that involves inhaling CO2 during reperfusion following ischemia. APC attenuates ischemic brain injury although the underlying mechanisms have not been elucidated. Here we report that APC reinforces ischemia-reperfusion-induced mitophagy in middle cortical artery occlusion (MCAO)-treated mice, and in oxygen-glucose deprivation (OGD)-treated brain slices and neurons...
