Cigarette smoking (CS) is associated with vascular endothelial dysfunction in a causative way primarily related to the TS content of reactive oxygen species (ROS), nicotine, and inflammation. TS promotes glucose intolerance and increases the risk of developing type-2 diabetes mellitus (2DM) with which it shares other pathogenic traits including the high risk of cerebrovascular and neurological disorders like stroke via ROS generation, inflammation, and blood-brain barrier (BBB) impairment. Herein we provide evidence of the role played by nuclear factor erythroid 2-related factor (Nrf2) in CS-induced cerebrobvascular/BBB impairments and how these cerebrovascular harmful effects can be circumvented by the use of metformin (MF; a widely prescribed, firstline anti-diabetic drug) treatment...

International guidelines indicate that interventional closure of left atrial appendage and patent foramen ovale may be considered in selected patients for stroke prevention. These procedures appear, however, from the published literature, at high risk of uselessness and futility in the single case, if not even capable to induce harm and adverse events. In fact, all reported systematic reviews and meta-analyses have not shown in a convincing manner the superiority of these procedures in stroke prevention, taking into account the occurrence of possible complications also, as compared with alternative medical treatment...

Jacobsen syndrome is a rare chromosomal disorder caused by distal deletions in the long arm of chromosome 11. All patients with Jacobsen syndrome have Paris-Trousseau syndrome, a bleeding disorder that causes neonatal thrombocytopenia, and persistent platelet dysfunction. Despite that, to date there are no reported cases of hemorrhagic strokes occurring in patients with Jacobsen syndrome. In the last 6 years at least six cases of brain hemorrhages in patients with Jacobsen syndrome have occurred. In this report, we perform a retrospective review of these six cases...

Increased level of homocysteine (hHcy) in plasma is an accompanying phenomenon of many diseases, including a brain stroke. This study determines whether hyperhomocysteinemia (which is a risk factor of brain ischemia) itself or in combination with ischemic preconditioning affects the ischemia-induced neurodegenerative changes, generation of reactive oxygen species (ROS), lipoperoxidation, protein oxidation, and activity of antioxidant enzymes in the rat brain cortex. The hHcy was induced by subcutaneous administration of homocysteine (0...

Despite its key role in the molecular pathology of Alzheimer's disease (AD), the physiological function of amyloid precursor protein (APP) is unknown. Increasing evidence, however, points towards a neuroprotective role of this membrane protein in situations of metabolic stress. A key observation is the up-regulation of APP following acute (stroke, cardiac arrest) or chronic (cerebrovascular disease) hypoxic-ischemic conditions. While this mechanism may increase the risk or severity of AD, APP by itself or its soluble extracellular fragment APPsα can promote neuronal survival...

BACKGROUND: Women with hypertensive disorders in pregnancy, in particular early-onset preeclampsia, are at increased risk of developing cardiovascular disease later in life. These women have a more than two-fold increased risk to die from cardiovascular diseases. Most studies focused on identification of risk factors shortly after pregnancy. Less is known on the prevalence of risk factors or actual signs of cardiovascular disease 5 - 20 years later. The presence of hypertension or metabolic syndrome can be seen as an opportunity for preventive interventions to reduce the development of severe cardiovascular diseases like myocardial infarction and stroke...

Neurological injury is often associated with cardiac abnormalities, including electrophysiological issues. Cardioversion of acute atrial fibrillation (<48h' duration) without anticoagulation carries about a 0.7% risk of thromboembolism. There is limited data on managing acute atrial fibrillation specifically in the neuroscience intensive care unit (NSICU) setting. We sought to determine the safety of using intravenous (IV) amiodarone for restoring sinus rhythm in patients with presumed new onset atrial or ventricular tachycardia after neurological injury...

BACKGROUND: Stroke is the leading cause of mortality and disability worldwide. Several definite risk factors have been identified for stroke, although infectious factors might also contribute to stroke episodes through increased susceptibility or direct induction. CASE PRESENTATION: A 46-year-old Chinese male initially presented with fever, headache, and impaired memory and developed disturbance of consciousness after admission. A clinical diagnosis of Staphylococcus aureus sepsis, massive cerebral infarction and haemorrhagic transformation (left internal carotid arterial system, inflammatory thrombus) were made based on brain radiography, blood culture and postoperative pathological examinations...

Cerebral Venous Thrombosis (CVT), also known as cortical venous, cerebral sinus, cerebral venous sinus, or dural sinus thrombosis, is an infrequent grave condition affecting pregnant females, resulting from clot formation in one of the many outflow tracts of the brain. Although pregnancy-associated stroke or CVT is uncommon, the risk of stroke is greatly increased above the low baseline rate in young patients during late pregnancy and, even more so, during the puerperium. Haemorrhagic infarction can occur in the acute stage of CVT...

INTRODUCTION: Increased Carotid Intima Medial Thickness (CIMT) is associated with cardiovascular risk factors and vascular events like Coronary Artery Disease (CAD) and stroke. AIM: This study was designed to identify whether CIMT is increased in the children of parents with premature coronary artery disease and compare it with age and sex matched controls who are children of normal individuals. We also tried to compare and correlate the changes in CIMT if any, among the study group with relation to family history of diabetes and hypertension...

Asthma in the United States has become an important public health issue, with many physicians, regulators, and scientists elsewhere expressing concern that criterion air pollutants have contributed to a rising tide of asthma cases and symptoms. This paper studies recent associations (from 2008 to 2012) between self-reported asthma experiences and potential predictors, including age, sex, income, education, smoking, and county-level average annual ambient concentrations of ozone (O3) and fine particulate matter (PM2...

What gets measured gets managed. Funding of health services is substantially determined by operational activity and specific outcome indicators. In day-to-day clinical decision-making, surrogate markers, such as glycosylated haemoglobin and blood pressure, are commonly used to modify risks of 'hard' outcomes that include kidney failure, ischaemic cardiac events, stroke and all-cause mortality. In many settings, surrogates are all we have to go on. As a consequence, current health funding models heavily rely on surrogate-based key performance indicators [KPIs]...

Stroke is one of the leading causes of death and probably the greatest cause of adult disability worldwide. Diabetes mellitus (DM) is a state of accelerated aging of blood vessels. Patients with diabetes have increased risk of stroke. Hyperglycemia represents a risk factor for poor outcome following stroke, and probably is just a marker of poor outcome rather than a cause. Lowering of blood glucose levels has not been shown to improve prognosis. Also, prevention of stroke risk among patients with DM is not improved with therapy for reduction of glucose levels...

INTRODUCTION: The number of patients receiving chronic dialysis treatment in Japan currently exceeds 300,000 people. Few reports have described carotid endarterectomy(CEA)for chronic renal failure patients because of the unacceptable rate of perioperative stroke and other morbidities. A strategy for and treatment results of CEA for chronic renal failure patients in our hospital are described herein. METHODS: The present study included 6 patients who underwent CEA while receiving dialysis treatment between April 2011 and November 2014...

OBJECTIVE: To explore the association between postmenopausal hormone therapy (HT) and Alzheimer disease (AD). METHODS: Twenty-year follow-up data from the Kuopio Osteoporosis Risk Factor and Prevention study cohort were used. Self-administered questionnaires were sent to all women aged 47-56 years, residing in Kuopio Province starting in 1989 until 2009, every 5th year. Register-based information on HT prescriptions was available since 1995. Probable AD cases, based on DSM-IV and National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association criteria, were identified from the special reimbursement register (1999-2009)...

Post-stroke epilepsy (PSE) is a common complication after stroke, yet treatment options remain limited. While many physicians prescribe antiepileptic drugs (AED) for secondary prevention of PSE, it is unclear which treatments are most effective in the prevention of recurrence of symptoms, or whether such therapy is needed for primary prevention. This review discusses the current understanding of epidemiology, diagnoses, mechanisms, risk factors, and treatments of PSE.

BACKGROUND: Cardiovascular diseases (CVDs) are now in a rising trend in South East Asia including Myanmar due to increase in major cardiovascular risk factors in both urban and rural areas, such as smoking, obesity and diabetes mellitus. It is necessary to determine CVD morbidities in Myanmar for planning of prevention and control activities for CVDs. The cross-sectional household survey was conducted in 2012 with 600 people aged 40 years and above in four townships (Kyauk-Tan, Mawlamyaing, Pathein and Pyay) and used face-to-face interview with standard questionnaire [Rose Angina Questionnaire and Questionnaire by European Cardiovascular Indicators Surveillance Set (EUROCISS) Research Group] to determine the level of reported CVD morbidities in adult population...
