Delayed Administration of Angiotensin II Type 2 Receptor (AT2R) Agonist Compound 21 Prevents the Development of Post-stroke Cognitive Impairment in Diabetes Through the Modulation of Microglia Polarization
AbstractA disabling consequence of stroke is cognitive impairment, occurring in 12% –48% of patients, for which there is no therapy. A critical barrier is the lack of understanding of how post-stroke cognitive impairment (PSCI) develops. While 70% of stroke victims present with comorbid diseases such as diabetes and hypertension, the limited use of comorbid disease models in prec linical research further contributes to this lack of progress. To this end, we used a translational model of diabetes to study the development of PSCI. In addition, we evaluated the application of compound 21 (C21), an angiotensin II Type 2 rece...

Imbalance in the force: the dark side of the microbiota on stroke risk and progression.
Abstract The composition of the gut microbiota depends on many factors, including our lifestyle, diet, metabolism, antibiotic use and hygiene. The contribution of these factors in shaping the gut microbiota and the subsequent effects on the prevention and development of stroke has been under intense investigation. Furthermore, several reports have uncovered the impact of stroke on intestinal dysfunction and gut dysbiosis, highlighting the delicate interplay between the brain, gut and microbiome following this acute brain injury. Despite our growing appreciation of the gut microbiota in shaping brain health, the im...

The 2-Minute Spontaneous Swallowing Screening Predicts Independence on Enteral Feeding in Patients with Acute Stroke
It is recommended that enteral feeding should be offered to patients with dysphagia estimated to be unable to take adequate diet orally within 7 days of admission after acute stroke, but there is no clear criterion for initiation of enteral feeding. Recent studies have reported that the frequency of spontaneous swallowing is useful in screening for dysphagia in acute stroke. The present study was aimed to investigate whether measurement of frequency of spontaneous swallowing for 2 minutes could predict independence on enteral feeding 1 week after admission in patients with acute stroke.

The gut microbiome in neurological disorders
Publication date: Available online 18 November 2019Source: The Lancet NeurologyAuthor(s): John F Cryan, Kenneth J O'Riordan, Kiran Sandhu, Veronica Peterson, Timothy G DinanSummaryResearch into the role of the gut microbiome in modulating brain function has rapidly increased over the past 10 years, albeit chiefly in animal models. Increasing clinical and preclinical evidence implicates the microbiome as a possible key susceptibility factor for neurological disorders, including Alzheimer's disease, autism spectrum disorder, multiple sclerosis, Parkinson's disease, and stroke. Cross-sectional clinical studies are bolstering ...

Adjustment of oral diet based on flexible endoscopic evaluation of swallowing (FEES) in acute stroke patients: a cross-sectional hospital-based registry study
Diagnosing dysphagia in acute stroke patients is crucial, as this comorbidity determines morbidity and mortality; we therefore investigated the impact of flexible nasolaryngeal endoscopy (FEES) in acute stroke...

Effects of dietary 5-methoxyindole-2-carboxylic acid on brain functional recovery after ischemic stroke.
Abstract Stroke leads to devastating outcomes including impairments of sensorimotor and cognitive function that may be long lasting. New intervention strategies are needed to overcome the long-lasting effects of ischemic injury. Previous studies determined that treatment with 5-methoxyindole-2-carboxylic acid (MICA) conferred chemical preconditioning and neuroprotection against stroke. The purpose of the current study was to determine whether the preconditioning can lead to functional improvements after stroke (done by transient middle cerebral artery occlusion). After 4 weeks of MICA feeding, half the rats underw...

Aryl hydrocarbon receptor modulates stroke-induced astrogliosis and neurogenesis in the adult mouse brain
The aryl hydrocarbon receptor (AHR) is a ligand-dependent transcription factor activated by environmental agonists and dietary tryptophan metabolites for the immune response and cell cycle regulation. Emerging...

Mediterranean diet: The role of long-chain ω-3 fatty acids in fish; polyphenols in fruits, vegetables, cereals, coffee, tea, cacao and wine; probiotics and vitamins in prevention of stroke, age-related cognitive decline, and Alzheimer disease.
Authors: Román GC, Jackson RE, Gadhia R, Román AN, Reis J Abstract The mechanisms of action of the dietary components of the Mediterranean diet are reviewed in prevention of cardiovascular disease, stroke, age-associated cognitive decline and Alzheimer disease. A companion article provides a comprehensive review of extra-virgin olive oil. The benefits of consumption of long-chain ω-3 fatty acids are described. Fresh fish provides eicosapentaenoic acid while α-linolenic acid is found in canola and soybean oils, purslane and nuts. These ω-3 fatty acids interact metabolically with ω-6 fatty acids mainly linoleic...

Extra-virgin olive oil for potential prevention of Alzheimer disease.
Authors: Román GC, Jackson RE, Reis J, Román AN, Toledo JB, Toledo E Abstract Observational epidemiological studies provide valuable information regarding naturally occurring protective factors observed in populations with very low prevalences of vascular disease. Between 1935 and 1965, the Italian-American inhabitants of Roseto (Pennsylvania, USA) observed a traditional Italian diet and maintained half the mortality rates from myocardial infarction compared with neighboring cities. In the Seven Countries Study, during 40years (1960-2000) Crete maintained the lowest overall mortality rates and coronary heart dise...

Smooth muscle cell-specific knockout of FBW7 exacerbates intracranial atherosclerotic stenosis.
Abstract Intracranial atherosclerotic stenosis (ICAS), the most common cause of stroke worldwide, is associated with high risk of recurrent ischemic stroke. F-box and WD repeat domain containing protein 7 (FBW7), an ubiquitin E3 ligase, is recently suggested to be involved in atherogenesis. However, whether FBW7 affects cerebrovascular remodeling during ICAS remains unknowns. We found that the expression of FBW7 was decreased in mouse brain microvessels from high-fat diet (HFD)-fed atherosclerotic mice. The reduced FBW7 expression was negatively associated with the remodeling of middle cerebral artery (MCA). Speci...

Moderate Protein Restriction Protects Against Focal Cerebral Ischemia in Mice by Mechanisms Involving Anti-inflammatory and Anti-oxidant Responses
AbstractFood composition influences stroke risk, but its effects on ischemic injury and neurological deficits are poorly examined. While severe reduction of protein content was found to aggravate neurological impairment and brain injury as a consequence of combined energy-protein malnutrition, moderate protein restriction not resulting in energy deprivation was recently suggested to protect against perinatal hypoxia-ischemia. Male C57BL6/j mice were exposed to moderate protein restriction by providing a normocaloric diet containing 8% protein (control: 20% protein) for 7, 14, or 30  days. Intraluminal middle cerebral arte...

Diabetic Stroke Promotes a Sexually Dimorphic Expansion of T Cells
AbstractWe recently reported that diabetes negates the cerebrovascular protection typically seen in adult female rats resulting in cognitive impairment, which is worsened by increased parenchymal bleeding and edema after ischemic stroke. Although women experience more severe diabetes and suffer from a higher rate of diabetic complications, including stroke and cognitive impairment, underlying mechanisms contributing to sex differences are limited. Emerging evidence suggests interleukin (IL)-17 contributes to cerebrovascular pathologies: (1) high salt diet-mediated expansion of IL-17-producing T cells (Th17) in the gut micr...

Potential Applications of Remote Limb Ischemic Conditioning for Chronic Cerebral Circulation Insufficiency
Conclusion Due to its long-term and often invisible course, CCCI has received less attention than acute cerebral ischemic stroke. However, without appropriate intervention, CCCI may lead to a variety of adverse events. Because the pathophysiological changes associated with CCCI are complex, pharmacological research in this area has been disappointing. Recent research suggests that RLIC, which is less invasive and more well-tolerated than drug treatment, can activate endogenous protective mechanisms during CCCI. In the present report, we reviewed studies related to CCCI (Table 1), as well as those related to stroke and sta...
