Stroke, also known as cerebrovascular accident, is an acute cerebrovascular disease with a high incidence, disability rate, and mortality. It can disrupt the interaction between the cerebral cortex and external muscles. Corticomuscular coherence (CMC) is a common and useful method for studying how the cerebral cortex controls muscle activity. CMC can expose functional connections between the cortex and muscle, reflecting the information flow in the motor system. Afferent feedback related to CMC can reveal these functional connections...

Thalamic pain syndrome is a distressing type of central post-stroke pain (CPSP) that occurs in up to 10% of cases following a cerebrovascular accident, typically with a delayed onset of signs and symptoms, and is often chronic or even life-long. Thalamic pain syndrome, as is the case for other CPSPs, is difficult to treat, and the response is typically moderate at best. Central pain also occurs after vascular insults in parts of the CNS other than the thalamus. Only a few patients present with the classic "Dejerine and Roussy syndrome," so the term CPSP is preferred for describing neuropathic pain after stroke...

Carotid artery dissection (CAD) is a condition that compromises blood flow and leads to serious complications such as a stroke or cerebrovascular accident (CVA). This case report demonstrates an unusual case of right internal carotid artery dissection, stenosis of >70%, and an intraluminal thrombus. The patient presented to the emergency department with complaints of right-sided neck pain and severe headache status-post a complicated pregnancy. A computed tomography (CT) angiogram of the right carotid was conducted and showed a right internal carotid artery dissection with 70% luminal stenosis and thrombosis...

Stroke remains a top contributor to long-term disability in the United States and substantially limits a person's physical activity. Decreased cardiovascular capacity is a major contributing factor to activity limitations and is a significant health concern. Addressing the cardiovascular capacity of stroke survivors as part of poststroke management results in significant improvements in their endurance, functional recovery, and medical outcomes such as all-cause rehospitalization and mortality. Incorporation of a structured approach similar to the cardiac rehabilitation program, including aerobic exercise and risk factor education, can lead to improved cardiovascular function, health benefits, and quality of life in stroke survivors...

Aphasia is a systemic disorder of formed speech that develops as a result of local brain lesions. Most aphasias are characterized by damage to secondary cortical fields, which in turn are responsible for the performance of the functions of gnosis and praxis, which explains the variability in the manifestations of speech disorders in patients with acute cerebrovascular accidents. However, it is necessary in each case to diagnose the central pathological mechanism, which underlies the development of the entire syndrome and determines the entire clinical picture...

Ischemic stroke, which accounts for 87% of cerebrovascular accidents, is responsible for massive global burden both in terms of economic cost and personal hardship. Many stroke survivors face long-term disability-a phenotype associated with an increasing number of genetic variants. While clinical variables such as stroke severity greatly impact recovery, genetic polymorphisms linked to functional outcome may offer physicians a unique opportunity to deliver personalized care based on their patient's genetic makeup, leading to improved outcomes...

Polycystic ovary syndrome (PCOS) is the leading cause of endocrine disorders among females of reproductive age and is linked with autoimmune disorders. PCOS has been associated with autoantibodies such as antinuclear antibody (ANA), anti-thyroid, and anti-Smith (anti-SM). Young patients with PCOS and systemic lupus erythematosus (SLE) have up to a 10-fold increase in stroke. We present a case of a patient with a history of PCOS (on metformin), hypothyroidism, and pulmonary embolism who presented to the emergency room with acute left-sided weakness...

BACKGROUND: Reduced oxygen delivery (DO2 ) during cardiopulmonary bypass (CPB) was proposed as a risk factor for the development of postoperative neurological complications (PONCs), including cerebrovascular accidents (CVA), delirium, and postoperative cognitive dysfunction (POCD). We aimed to review the current evidence on the association between intraoperative DO2 and the incidence of PONCs. METHODS: MEDLINE, Embase, the Cochrane Library, and Web of Science were electronically searched to identify comparative studies from inception until July 2023 that reported the association between intraoperative DO2 levels and the incidence of PONCs (as defined by the scales and diagnostic tools utilized by the studies' authors) in adults patients undergoing cardiac surgery using CPB...

IMPORTANCE: Racial and ethnic disparities exist in urogynecologic surgery; however, literature identifying specific disparities after sling operations for stress incontinence are limited. OBJECTIVE: The objective of this study was to evaluate racial and ethnic disparities in surgical complications within 30 days of midurethral sling operations. STUDY DESIGN: This retrospective cohort study identified women who underwent an isolated midurethral sling operation between 2014 and 2021 using the American College of Surgeons National Surgical Quality Improvement Program database...

UNLABELLED: Peripheral vascular dysfunction, measured as flow-mediated dilation (FMD), is present across all phases of stroke recovery and elevates risk for recurrent cardiovascular events. The objective of this systematic review and meta-analysis was to characterize baseline FMD in individuals post-stroke, with consideration for each phase of stroke recovery. METHODS: Three databases (PubMed, CINAHL, and Embase) were searched between January 1st , 2000 and October 12th , 2023 for studies that examined baseline FMD in stroke...

OBJECTIVES: To determine the risk difference of arterial and venous thromboembolic events between patients with upper gastrointestinal bleeding (UGIB) who received and did not receive tranexamic acid. DESIGN: Retrospective cohort study. SETTING: The TriNetX Analytics (Cambridge, MA) Research Network, a deidentified mixed electronic health record and claims-derived database with over 110 million patients, primarily located in the United States...

OBJECTIVE: To determine the optimal treatment strategy for patients with asymptomatic carotid stenosis. MATERIAL AND METHODS: The authors reviewed clinical guidelines for the management of patients with asymptomatic carotid stenosis 60-99%, as well as medical studies and meta-analyses comparing carotid endarterectomy and optimal drug therapy in asymptomatic patients between 1993 and 2023. RESULTS: The choice of treatment strategy for patients with asymptomatic carotid artery stenosis is still a controversial issue...

AIMS: Perioperative stroke remains a devastating complication after transcatheter aortic valve implantation (TAVI), and using a cerebral embolic protection device (CEPD) during TAVI may reduce the occurrence of stroke according to some studies. Therefore, we conducted this meta-analysis to determine whether CEPD should be routinely used during TAVI. METHODS AND RESULTS: The inclusion criteria for this study were randomized controlled trials (RCTs) that examined the outcome of stroke with or without CEPD during TAVI, with a minimum follow-up period of 30 days...

Patent foramen ovale (PFO) is the most common interatrial septal abnormality. The indications for PFO device closure are still being evaluated, with the most common reason being to prevent cerebrovascular accidents (CVA) caused by paradoxical embolism of deep vein thrombosis (DVT) in the lower extremities. This procedure is usually performed through percutaneous intervention using femoral vein access. Here, we present a case of PFO closure using a transhepatic approach, as femoral vein access was not feasible due to an interrupted inferior vena cava (IVC)...

INTRODUCTION: This study evaluates the implications of drug intoxication (DI) on donor utilization and outcomes in liver transplantation (LT). METHODS: The UNOS STAR database was evaluated for all potential donors and adult, first-time, whole LT between 2005 and 2019. Logistic regression analyses evaluated liver utilization; proportional hazards modeling assessed risk of 1-year graft loss. RESULTS: A total of 132 783 potential donors (10 205, 7...

BACKGROUND: Previous studies have suggested relationship between diverticular disease and cardiovascular disease. Since cardiovascular disease and cerebrovascular accident share a lot of pathogenesis, diverticulitis could also be a risk factor for stroke. This study tried to establish epidemiological evidence of the relationship between colon diverticulitis and ischemic stroke. METHODS: In this retrospective cohort study, patients with newly diagnosed colon diverticulitis (N = 6238) and patients without colon diverticulitis (control group; N = 24 952) were recruited between January 1, 2000, and December 31, 2017...

INTRODUCTION: Blunt cerebrovascular injury (BCVI) occurs in 1-3% of blunt traumas and is associated with stroke, disability, and mortality if unrecognized and untreated. Early detection and treatment are imperative to reduce the risk of stroke, however, there is significant variation amongst centers and trauma care providers in the specific medical management strategy used. This study compares antiplatelets vs. anticoagulants to determine BCVI-related stroke risk and bleeding complications to better understand the efficacy and safety of various treatment strategies...

Ischemic stroke is defined as a reduction in blood flow to brain tissue that results in the deterioration and death of neurons in a matter of minutes. While often seen in older patients with a history of atherosclerosis of the major arteries, a subset of ischemic strokes occur in younger individuals with minimal to no prior risk factors. Further evaluation of these unknown, or cryptogenic, strokes has yielded positive findings of a patent foramen ovale (PFO) in a concerning number of cases. Cryptogenic strokes attributable to PFO present an important clinical occurrence because they do not fit the typical template regarding those most at risk for such acutely devastating outcomes, making their identification uniquely important for both immediate and long-term patient care...

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an autosomal dominant genetic disorder of the small arteries that causes ischemic vascular events, subcortical dementia, behavioral changes, and migraine-like headaches. It is caused by a mutation in the NOTCH3 gene; this disease was first described in 1955 by van Bogaert. We present a 29-year-old woman who presented to the neurology department. She has no history of chronic degenerative diseases. She has been complaining of migraine-like headaches for the past six months...

INTRODUCTION: Along with cardiopulmonary bypass time, aortic cross-clamping time is directly related to the risk of complications after heart surgery. The influence of the time difference between cardiopulmonary bypass and cross-clamping times (TDC-C) remains poorly understood. OBJECTIVE: To assess the impact of cardiopulmonary bypass time in relation to cross-clamping time on immediate results after coronary artery bypass grafting in the Registro Paulista de Cirurgia Cardiovascular (REPLICCAR) II...
