Smartphone-Enabled Point-of-Care Testing for Prehospital Stroke Diagnosis.

Objectives: The objective of this study was to evaluate the feasibility of point-of-care testing (POCT) devices for N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurement in prehospital settings, with the aim of improving the speed and accuracy of stroke diagnosis, thereby facilitating quicker and more effective patient care.

Methods: Prehospital blood samples were collected from suspected stroke patients, and NT-proBNP levels were measured using a POCT device in ambulances and hospitals. Results from the NT-proBNP POCT and smartphone images were analyzed.

Attitudinal factors associated with protein sufficiency in Chilean vegan university students - A pilot study.

Introduction: vegan diets are currently an essential topic of discussion because they are recognized as a prototype of a healthy diet but are also associated with deficits in the intake of critical nutrients such as protein. Evaluating the factors that influence the deficit in their intake in vulnerable populations such as university students represents an important topic of interest, considering that this is one of the groups where veganism is most popular. Given this, the present study aimed to determine the degree of protein sufficiency and its associated factors in a sample of Chilean vegan university students.

Mediterranean Diet and its Effects on Silent Brain Infarcts in a Cohort of Patients With Atrial Fibrillation.

Background And Aims: The benefits of Mediterranean Diet (MeDiet) in prevention of cardiovascular diseases (CVD) in general and ischemic stroke (IS) have been extensively studied and reported. We hypothesize that the consumption of nutrients typical of MeDiet would also reduce the rate of silent brain infarcts (SBI) among AF patients.

Methods And Results: Patients with a history of AF who scored 0 to 1 in the CHADS2 score, ⩾50 years and with absence of neurological symptoms were selected from Seville urban area using the Andalusian electronic healthcare database.

Intensive 90-day textile wearable Holter monitoring: an alternative to detect paroxysmal atrial fibrillation in selected patients with cryptogenic stroke.

We aimed to demonstrate the feasibility of 90-day cardiac monitoring with an external Holter device and to find a target population able to benefit from such a technique. Cryptogenic stroke patients were continuously monitored for 90 days with a textile wearable Holter (TWH). Compliance and quality of the monitoring were assessed by the number of hours of ECG stored per month.

Blood-Based Biomarkers to Search for Atrial Fibrillation in High-Risk Asymptomatic Individuals and Cryptogenic Stroke Patients.

Background: Atrial fibrillation (AF) increases the risk of ischemic stroke in asymptomatic individuals and may be the underlying cause of many cryptogenic strokes. We aimed to test the usefulness of candidate blood-biomarkers related to AF pathophysiology in two prospective cohorts representative of those populations.

Methods: Two hundred seventy-four subjects aged 65-75 years with hypertension and diabetes from the AFRICAT cohort, and 218 cryptogenic stroke patients aged >55 years from the CRYPTO-AF cohort were analyzed.

Combining the mechanical ball milling of the carbohydrate and the use of low solvent reaction media for the synthesis of fructose fatty acid esters by immobilized lipases.

Synthesis of carbohydrate fatty acid esters catalyzed by immobilized lipases is a pathway to obtain specific isomers from renewable feedstock, compared to unselective chemical esterification. While the use of low-solvent reaction media (≤ 10 %) offers advantages, the interactive effects of these media with biocatalysts and substrates should be modulated towards high catalytic efficiency and substrate availability. Among the investigated co-solvents, tert-butanol and DMSO in a mixture of lauric acid substrate/co-solvent (90/10; v/v) resulted in high bioconversion yields using either Novozym® 435 or Lipozyme® RM IM, as biocatalysts.

Muscle MRI characteristic pattern for late-onset TK2 deficiency diagnosis.

Background And Objective: TK2 deficiency (TK2d) is a rare mitochondrial disorder that manifests predominantly as a progressive myopathy with a broad spectrum of severity and age of onset. The rate of progression is variable, and the prognosis is poor due to early and severe respiratory involvement. Early and accurate diagnosis is particularly important since a specific treatment is under development.

Proteins and pathways in atrial fibrillation and atrial cardiomyopathy underlying cryptogenic stroke.

Background: Atrial fibrillation (AF) is one of the most prevalent causes of cryptogenic stroke. Also, apart from AF itself, structural and remodelling changes in the atria might be an underlying cause of cryptogenic stroke. We aimed to discover circulating proteins and reveal pathways altered in AF and atrial cardiomyopathy, measured by left atrial volume index (LAVI) and peak atrial longitudinal strain (PALS), in patients with cryptogenic stroke.

Early Neurological Change After Ischemic Stroke Is Associated With 90-Day Outcome.

Background And Purpose: Large-scale observational studies of acute ischemic stroke (AIS) promise to reveal mechanisms underlying cerebral ischemia. However, meaningful quantitative phenotypes attainable in large patient populations are needed. We characterize a dynamic metric of AIS instability, defined by change in National Institutes of Health Stroke Scale score (NIHSS) from baseline to 24 hours baseline to 24 hours (NIHSS - NIHSS = ΔNIHSS), to examine its relevance to AIS mechanisms and long-term outcomes.

Predicting Atrial Fibrillation with High Risk of Embolization with Atrial Strain and NT-proBNP.

The aim of the study was to determine markers of atrial dysfunction in patients with cryptogenic stroke to predict episodes of paroxysmal atrial fibrillation with high risk of embolization (HpAF). We classified patients included in the Crypto-AF study, Cryptogenic Stroke registry, to detect paroxysmal atrial fibrillation (pAF) with wearable Holter, according to the longest episode of pAF in three groups: without pAF detection, episodes of pAF shorter than 5 h, and episodes of pAF longer than 5 h (HpAF). Atrial dysfunction surrogates were evaluated: EKG pattern, Holter record and echocardiography parameters (left atria volume (LAVI), and peak atrial longitudinal and contraction strain (PALS and PACS).

Discriminative value of glial fibrillar acidic protein (GFAP) as a diagnostic tool in acute stroke. Individual patient data meta-analysis.

Glial fibrillar acidic protein (GFAP) in serum has been evaluated as a promising biomarker to differentiate between intracerebral hemorrhage (ICH) and acute ischemic stroke (AIS). We assessed its value as diagnostic and prognostic tool for ICH through a literature systematic review and individual patient data (IPD) meta-analysis.We performed a systematic search in PubMed database until November 2018 for publications that evaluated GFAP to differentiate AIS and ICH within 4.

Prevalence and risk factors of silent brain infarcts in patients with AF detected by 3T-MRI.

Background: Silent brain infarcts (SBI), a finding on neuroimaging, are associated with higher risk of future stroke. Atrial Fibrillation (AF) has been previously identified as a cause of SBI.

Objectives: The aim of this study is to determine the prevalence of and risk factors for SBI in patients with AF and low-to-moderate embolic risk according to CHADS and CHADSVASc score.

Circulating microRNA after autologous bone marrow mononuclear cell (BM-MNC) injection in patients with ischemic stroke.

Previous studies have shown the potential of microRNAs (miRNA) in the pathological process of stroke and functional recovery. Bone marrow mononuclear cell (BM-MNC) transplantation improves recovery in experimental models of ischemic stroke that might be related with miRNA modifications. However, its effect on circulating miRNA has not been described in patients with stroke.

Frequency and distribution of HPV genotypes in 800 genital samples of Ecuadorian men and women from the city of Guayaquil.

Even though there are data published on HPV epidemiology in Ecuador, the distribution of genotypes in Guayaquil, the largest city in the country, has not been previously determined in a study including including both, men and women. The present study aimed to determine the distribution of 37 HPV genotypes in genital samples from Ecuadorian men and women living in the city of Guayaquil. Genital samples included in daily diagnostic routine were analyzed by the 37 HPV GenoArray Diagnostic Kit (Hybribio® Ltd.

Pharmacoperone IN3 enhances the apoptotic effect of leuprolide in prostate cancer cells by increasing the gonadotropin-releasing hormone receptor in the cell membrane.

Gonadotropin-releasing hormone (GnRH) agonists are widely used for the treatment of advanced prostate cancer (PCa). Agonists activate the GnRH receptor (GnRH-R), triggering apoptosis in PCa cells. In gonadotropes, the amount of GnRH-R in the plasma membrane is regulated by protein folding and endoplasmic reticulum retention, mechanisms that can be overcome by the pharmacoperone IN3.
