Stroke

BACKGROUND: The health effect of particulate matter pollution on stroke has been widely examined; however, the effect among patients with comorbid type 2 diabetes (T2D) in developing countries has remained largely unknown. METHODS: A time-series study was conducted to investigate the short-term effect of fine particulate matter (PM2.5 ) and inhalable particulate matter (PM10 ) on hospital admissions for stroke among patients with T2D in Beijing, China, from 2014 to 2018...

OBJECTIVE: We aimed to evaluate the association between baseline plasma zinc and the development of proteinuria as well as possible effect modifiers in hypertensive patients. METHODS: This is a subset of the China Stroke Primary Prevention Trial (CSPPT) Renal Sub-Study. In the CSPPT, participants were randomized to receive a daily oral dose of 1 tablet containing 10 mg enalapril and 0.8 mg folic acid or 1 tablet containing 10 mg enalapril only. A total of 783 participants with plasma zinc measurements and without proteinuria at baseline were included in the current study...

BACKGROUND AND OBJECTIVES: There is conflicting data regarding the association between platelet parameters and prognosis of stroke patients treated with intravenous thrombolysis. We aimed to analyze this association in a cohort of patients treated with rtPA. MATERIAL AND METHODS: Retrospective, observational study in adult ischemic stroke patients treated with rtPA between January 2015 and February 2017. Demographic and clinical characteristics, stroke severity (NIHSS), etiology (TOAST), mean platelet volume (MPV), platelet count (PC), platelet distribution width (PDW) and functional outcome (mRS) at discharge and 90 days were recorded...

INTRODUCTION: Understanding the underlying mechanisms in ischemic stroke (IS) in young adults remains challenging. Thrombin activates processes that contribute to the development and progression of arterial diseases. We investigated the association between thrombin generation (TG) and a first IS or transient ischemic attack (TIA) in young adults. METHODS: In this case-control study, we included consecutive patients (≤45 years in men, ≤55 years in women) with a first IS or TIA (n = 160) and healthy controls (n = 160)...

OBJECTIVES: Risk assessment models must be continuously validated and updated to ensure that predictions remain valid. Here, the Endovascular Aneurysm Repair Risk Assessment Model, developed in 2008, is updated and improved. METHODS: We used prospectively collected data from Australian patients who underwent elective endovascular aneurysm repair between 2009 and 2013 (n=695). Data were provided by treating surgeons and the National Death Index. Key outcomes were early and mid-term survival, early complications (endoleak, operative, and graft-related) and late complications (endoleak and graft-related)...

INTRODUCTION: Following a carotid endarterectomy (CEA) procedure, patients are discharged to their homes or other locations than home such as an acute care facility or skilled nursing facility based on their functional status and level of medical attention needed. Decision-making for discharge destination following a CEA to home or non-home locations is important due to the differences in survival and post-operative complications. While primary outcomes such as mortality and occurrence of stroke following CEA have been extensively studied, there is a paucity of information characterizing outcomes of discharge destination and the factors associated...

OBJECTIVE: To assess the effect of age on mechanisms of exercise tolerance. METHODS: Prospective observational study recruited 71 healthy individuals divided into two groups according to their age i.e. younger (≤40 years of age, N = 43); and older (≥55 years of age, N = 28). All participants underwent maximal graded cardiopulmonary exercise stress testing using cycle ergometer with simultaneous non-invasive gas-exchange and central haemodynamic measurements...

Fatigue is affected by both peripheral and central factors. However, the interrelationship between muscle fatigue and brain activity has not yet been clarified. This study aimed to clarify the effect of muscle fatigue due to sustained pinch movement on brain activity in healthy individuals using functional near-infrared spectroscopy (fNIRS). Ten healthy adults participated in the study. Pinch movement of isometric contraction was the task to be performed, and electromyogram of the first dorsal interosseous muscle and brain activity by fNIRS were measured in this period...

BACKGROUND: In recent years, LRG1 was found to be closely related to atrial fibrillation, heart failure, and myocardial remodeling after myocardial infarction. While its role in cerebral infarction was still controversial. We aimed to explore the value of LRG1 to identify the cardioembolic stroke. METHODS: 283 acute ischemic stroke(AIS) patients and 169 controls were enrolled. The AIS patients were divided into a CE(cardiogenic embolism) group and a non-CE group...

Összefoglaló. Bevezetés: A stroke kezelésének lehetőségei az utóbbi években jelentősen megváltoztak: a thrombolysis után bevezetésre került a mechanikus thrombectomia, és a terápiás időablak is jelentősen kitágult az utóbbi évek nagy multicentrikus tanulmányai alapján. Ezek a lehetőségek új igényeket fogalmaztak meg a képalkotó diagnosztikával szemben: az ischaemia okozta morfológiai elváltozások mellett az artériás és a kollaterális rendszer állapotát, valamint bizonyos esetekben az agy szöveti perfúzióját is szükséges meghatározni...

AIMS: This pilot study aimed to evaluate the effects of motor imagery training on lower limb motor function of stroke patients. BACKGROUND: Motor imagery training has played an important role in rehabilitation outcomes of stroke patients. METHODS: In this pilot randomized controlled trial 32 stroke patients were randomly divided into experimental and control groups from January to June 2017. Patients in both groups received conventional neuro-rehabilitation five times a week in 3-h segments for 6 weeks...

INTRODUCTION: There is increased risk of stroke and other neurological complications in HIV with no large population-based studies in the literature. We aim to evaluate the prevalence of stroke, HIV-associated neurological complications and identify risk factors associated with poor outcome of stroke among HIV admissions in the US. METHODS: In the Nationwide Inpatient Sample with adult HIV hospitalizations, patients with primary cerebrovascular disease (CeVDs) and HIV-associated neurological complications were identified by ICD-9-CM codes...

Glomerulopathy with Fibronectin Deposits (GFND) is a rare, autosomal dominant disease characterized by proteinuria, hematuria and progressive renal failure associated with glomerular deposition of fibronectin, frequently resulting in end-stage renal disease (ESRD). There is no established treatment for this condition beyond conservative measures such as blood pressure control and the use of angiotensin-converting enzyme (ACE) inhibitors. We present a case of GFND associated with progressive chronic kidney disease (CKD) and nephrotic range proteinuria showing a sustained response to prednisone treatment...

PURPOSE OF REVIEW: While traditionally encountered in ambulatory settings, bruxism occurs in patients with a variety of acute neurologic illnesses including encephalitis, intracerebral hemorrhage, traumatic brain injury, hypoxic-ischemic encephalopathy, and acute ischemic stroke. Untreated bruxism in acute neurologic illness can lead to tooth loss, difficulty in mouth care resulting in recurrent aspiration pneumonia, endotracheal tube dislodgement, and even tongue laceration or amputation...

Heart failure (HF) can be considered a disease of older people. It is a leading cause of hospitalisation and is associated with high rates of morbidity and mortality in the over-65s. In 2012, an editorial in this journal detailed the latest HF research and guidelines, calling for greater integration of geriatricians in HF care. This current article reflects upon what has been achieved in this field in recent years, highlighting some future challenges and promising areas. It is written from the perspective of one such integrated team and explores the new role of cardiogeriatrician, working in a multidisciplinary team to deliver and improve care to increasingly complex, older, frail patients with multiple comorbidities who present with primary cardiology problems, especially decompensated HF...

The RACE trial was one of the first landmark trials to establish whether restoring and maintaining sinus rhythm could reduce morbidity and mortality in patients with atrial fibrillation (AF). Its neutral outcome shaped clinical decision-making for almost 20 years. However, there were two important treatment-related factors associated with mortality of rhythm control therapy at that time: One was safety of antiarrhythmic drug therapy, and the other one withdrawal of anticoagulation after restoration of sinus rhythm...

Current atrial fibrillation (AF) guidelines recommend screening for AF in individuals above 65 years or with other characteristics suggestive of increased stroke risk. Several mobile health (mHealth) approaches are available to identify AF. Although most wearables or ECG machines include algorithms to detect AF, an ECG confirmation of AF is necessary to establish a suspected diagnosis of AF. Early detection of AF is important to allow early initiation of AF management, and early rhythm control therapy lowered risk of adverse cardiovascular outcomes among patients with early AF aged >75 or with a CHA2DS2-VASc score ≥2 and cardiovascular conditions in the EAST-AFNET 4 study...

MiR-499a-5p was significantly downregulated in degenerative tissues and correlated with apoptosis. Nonetheless, the biological function of miR-499a-5p in acute ischemic stroke has been still unclear. In this study, we found that the plasma levels of miR-499a-5p were significantly downregulated in 64 ischemic stroke patients and negatively correlated with the National Institutes of Health Stroke Scale score. Then, we constructed cerebral ischemia/reperfusion (I/R) injury in rats after middle cerebral artery occlusion and subsequent reperfusion and oxygen-glucose deprivation and reoxygenation (OGD/R)-treated SH-SY5Y cell model...

Identifying patients with hypertension at high risk of cardio-metabolic multi-morbidity (CMM) is key for intervention. We examined the independent association of CMM with ethnicity and socioeconomic status (SES) among patients with uncontrolled hypertension. Demographic, socioeconomic, lifestyle, and clinical factors were obtained from 921 patients aged ≥40 years with hypertension in the multiethnic Singapore. CMM was defined as having ≥2 chronic diseases (diabetes mellitus, heart disease, stroke, and chronic kidney disease), which were confirmed by medical records or laboratory measurements...

Genetic alterations in COL4A2 are less common than those of COL4A1 and their fetal phenotype has not been described to date. We describe a three-generation family with an intragenic deletion in COL4A2 associated with a prenatal diagnosis of recurrent fetal intracerebral hemorrhage (ICH), and a myriad of cerebrovascular manifestations. Exome sequencing, co-segregation analysis, and imaging studies were conducted on eight family members including two fetuses with antenatal ICH. Histopathological evaluation was performed on the terminated fetuses...
