BACKGROUND: The European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) European Biological Variation Study (EuBIVAS) has been established to deliver rigorously determined biological variation (BV) indices. EuBIVAS determined BV for serum creatinine using the enzymatic and alkaline picrate measurement methods. METHOD: In total, 91 healthy individuals (38 males, 53 females; age range, 21-69 years) were bled for 10 consecutive weeks at 6 European laboratories...

OBJECTIVE: Considering the importance and the near future development of noninvasive Brain-Machine Interface (BMI) systems, this paper presents a comprehensive theoretical-experimental survey on the classification and evolutionary methods for BMI-based systems in which EEG signals are used. APPROACH: The paper is divided into two main parts. In the first part a wide range of different types of the base and combinatorial classifiers including boosting and bagging classifiers and also evolutionary algorithms are reviewed and investigated...

BACKGROUND: We demonstrated that heightened cough response to bronchoconstriction is a fundamental feature of cough variant asthma (CVA). To evaluate this physiological feature of CVA in daily clinical practice, it is necessary to clarify the cough response to bronchoconstriction in healthy subjects. We evaluated cough response to methacholine (MCh)-induced bronchoconstriction in healthy subjects. A forced oscillometry technique was used to measure airway resistance changes with Mch. METHODS: Healthy never-smokers (21 men, 20 women; mean 22...

OBJECTIVE: To estimate the incidence rate of clinically apparent arterial thrombotic events and associated comorbidities in patients with primary systemic vasculitis. METHODS: Using large cohort administrative data from Quebec, Canada, we identified patients with vasculitis, including polyarteritis nodosa (PAN) and granulomatosis with polyangiitis (GPA). Incident acute myocardial infarctions (AMIs) and cerebrovascular accidents (CVAs) after the diagnosis of vasculitis were ascertained in the PAN and GPA group via billing and hospitalization data...

BACKGROUND: We determined trends over time in cardiovascular and non-cardiovascular comorbidity in patients hospitalised for cardiovascular disease (CVD). METHODS: The Dutch nationwide hospital register was used to identify patients hospitalised for CVD during 2000-2010. Comorbidity was defined as a previous hospital admission for CVD other than the index CVD, cancer, diabetes, musculoskeletal and connective tissue disorders, respiratory disorders, thyroid gland disorders, kidney disorders and dementia in the five years previous to hospital admittance for the index CVD...

Fairly limited data reported the incidence and risk of cerebrovascular accident (CVA) in autosomal dominant polycystic kidney disease (ADPKD). Additionally, little is known regarding the therapeutic impact of renin-angiotensin-aldosterone system (RAAS) blockade and statin on reducing the occurrence of CVA in ADPKD. We utilized the data from Taiwan National Health Insurance Research Database (NHIRD) to perform a population-based cohort study (1997-2013). A total of 2,647 patients with ADPKD were selected from 1,000,000 general population after excluding patients with age<18, renal replacement therapy and concomitant diagnosis of CVA...

PURPOSE: Stem cell therapy is a promising modality for treatment of patients with chronic cerebrovascular accident (CVA) in whom treatment other than physiotherapy or occupational therapy does not address the repair or recovery of the lost function. In this study, the author aimed at evaluating CVA patients treated with human embryonic stem cell (hESC) therapy and comparing their study outcomes with globally accepted European Stroke Scale (ESS) to that with novel scoring system, Nutech functional score (NFS), a 21-point positional and directional scoring system for assessing patients with CVA...

AIMS: The use of left atrial appendage (LAA)-occluders in atrial fibrillation is increasing. There are few data on the comparison between transesophageal echocardiography (TEE) and computed tomography (MDCT) assessing peridevice-flow and outcome of electrical cardioversion (ECV) in these patients. METHODS AND RESULTS: Single-center prospective registry from 2009 to 2015 including all LAA-occluders to analyze success and complications during implantation and follow-up...

Arterial wall thickening, stimulated by low-grade systemic inflammation, underlies many cardiovascular events. As diet is a significant moderator of systemic inflammation, the dietary inflammatory index (DIITM) has recently been devised to assess the overall inflammatory potential of an individual's diet. The primary objective of this study was to assess the association of the DII with common carotid artery-intima-media thickness (CCA-IMT) and carotid plaques. To substantiate the clinical importance of these findings we assessed the relationship of DII score with atherosclerotic vascular disease (ASVD)-related mortality, ischaemic cerebrovascular disease (CVA)-related mortality and ischaemic heart disease (IHD)-related mortality more...

Cough variant asthma (CVA), as one of bronchitis diseases, features with repeated cough. In clinics, CAV does not show significant abnormal signs, therefore antibiotic therapy can hardly achieve satisfactory treatment effect. With the development of scientific technologies, the correlation between mycoplasma pneumoniae infection and CVA has become a hot research topic in clinics. In clinics, mycoplasma pneumoniae is extensively regarded as major cause for CVA, with complex pathogenic mechanism. The symptoms of CVA is characterized by chronic non abnormal inflammation, normally accompanied with bronchospasm and intestinal infection...

Data on biological variation for cobalamin and holotranscobalamin (holoTC) are limited. The aim of this study was to determine within-subject (CVI) and between-subject (CVG) biological variations for these analytes in a healthy population. We collected blood samples from 15 healthy volunteers (12 women and three men, 22-66 years) on the same weekday for 10 consecutive weeks. Serum samples were stored at -80 °C until analysis in duplicate in a single analytical run. The CVI and CVG were estimated by nested ANOVA...

OBJECTIVE: To determine whether anticyclic citrullinated peptide antibodies (anti-CCP) and rheumatoid factor (RF) are risk factors for 10-year cardiovascular disease (CVD) in patients with rheumatoid arthritis (RA). METHODS: Analyses were performed using data from the Nijmegen early RA inception cohort, in which patients with newly diagnosed RA, consecutively included since 1985, were regularly followed up. Anti-CCP and RF were determined at baseline (diagnosis)...

Poor adherence with medicine declines the clinical outcome of pharmacotherapy. It may carry serious sequelae especially in case of antihypertensive drugs like cerebrovascular accident (CVA). This study has been planned to find the association of poor adherence with anti-hypertensive with CVA in diabetic and non- diabetic patients. One hundred CVA patients who were admitted through Emergency in Abbasi Shaheed hospital, a tertiary care hospital in Karachi, were recruited from Jun 2013 till Dec 2013. The criteria of inclusion was, diagnosed case of CVA, with primary hypertension, availability of patient's therapeutic record, consent of the patient or legal successor/heir...

BACKGROUND: Blunt cerebrovascular injuries (BCVI) are rare with nonspecific predictors, making optimal screening critical. Radiation concerns magnify these issues in children. The Eastern Association for the Surgery of Trauma (EAST) criteria, the Utah score (US) and the Denver criteria (DC) have been advocated for pediatric BCVI screening, though direct comparison is lacking. We hypothesized that current screening guidelines inaccurately identify pediatric BCVI. METHODS: This was a retrospective cohort study of pediatric trauma patients treated from 2005-2015 with radiographically confirmed BCVI...

OBJECTIVES: Traditional interpretation of Fisher's Fundamental Theorem of Natural Selection is that life history traits (LHT), which are closely related with fitness, show lower heritabilities, whereas morphological traits (MT) are less related with fitness and they are expected to show higher heritabilities. In humans, although few studies have examined the heritability of LHT and MT, none of them have analyzed the same sample for comparative purposes. Here we assessed, for the first time, the heritability, additive genetic variance (VA ), residual variance (VR ) and coefficient of genetic additive variation (CVA ) values of LHT and MT in a singular collection of identified skulls with associated demographic records from Hallstatt (Austria)...
