Management of cerebral venous thrombosis in Spain: MOTIVATE descriptive study.

INTRODUCTION: Cerebral venous thrombosis (CVT) is an uncommon cause of stroke that mainly affects young adults. Early, accurate diagnosis can reduce the rate and severity of complications. OBJECTIVE: The aim of this study was to analyse the clinical characteristics, management, and treatment of CVT in different centres in Spain. METHODS: We conducted a multicentre, retrospective, descriptive study of patients hospitalised due to CVT between 2008 and 2017 at 10 Spanish centres. RESULTS: We included 256 patients, with a mean age (SD) of 49.8 (18.7) years; 51% of patients were women. The most frequent symptoms were headache (73%), focal deficits (50%), epileptic seizures (33%), and encephalopathy (21%). The most frequent localisations were the superior sagittal sinus (12.5%), the transverse sinus (10.9%), and 2 or more sinuses or veins (66.4%). Thrombophilia was the most frequent known aetiology (24%), and was most commonly associated with the prothrombin G20210A mutation (19%). Forty-six percent of patients were treated with antithrombotics for 3 to 6 months, 21% for one year, and 22.6% required indefinite anticoagulation. Endovascular therapy was performed in 5% of cases, and 33% required neurosurgery. Regarding outcomes, 75% of patients were independent at 3 months (modified Rankin Scale [mRS] score ≤ 2), with papilloedema (P =  .03), focal deficits (P = .001), and encephalopathy (P < .001) showing a statistically significant association with poor prognosis (mRS > 3). The in-hospital mortality rate was 4.3%, with a 3-month mortality rate of 6.3%. CONCLUSION: The diverse risk factors and variable presentation of CVT represent a challenge in the diagnosis and treatment of this condition. To improve prognosis and reduce mortality, it is essential to establish management protocols for this entity.

Technical-Tactical Performance Indicators During the Phases of Play in 3x3 Basketball / Indicadores de Rendimiento Técnico-Táctico Durante las Fases de Juego en Baloncesto 3x3

The current study aims to analyse technical-tactical performance indicators during elite 3x3 basketball games. To do so, the start, development and end of 315 attacking phases were examined using an observational tool during four games of the 3x3 Men's World Cup 2017. The results showed that efficacy from the 6.75 m line and the fast breaks made after defensive rebound were the performance indicators that best discriminated winning and losing teams. During set plays, the best percentages of efficacy were achieved with group-tactical situations involving the three players on court, and mainly with the use of off-ball screens. Coaches when preparing competitions and training drills can use these findings to increase team and player’s performance.(AU)

Safety and outcomes of routine endovascular thrombectomy in large artery occlusion recorded in the SITS Register: An observational study.

BACKGROUND AND OBJECTIVE: We aimed to evaluate the safety and outcomes of thrombectomy in anterior circulation acute ischaemic stroke recorded in the SITS-International Stroke Thrombectomy Register (SITS-ISTR) and compare them with pooled randomized controlled trials (RCTs) and two national registry studies. METHODS: We identified centres recording ≥10 consecutive patients in the SITS-ISTR with at least 70% of available modified Rankin Scale (mRS) at 3 months during 2014-2019. We defined large artery occlusion as intracranial internal carotid artery, first and second segment of middle cerebral artery and first segment of anterior cerebral artery. Outcome measures were functional independence (mRS score 0-2) and death at 3 months and symptomatic intracranial haemorrhage (SICH) per modified SITS-MOST. RESULTS: Results are presented in the following order: SITS-ISTR, RCTs, MR CLEAN Registry and German Stroke Registry (GSR). Median age was 73, 68, 71 and 75 years; baseline NIHSS score was 16, 17, 16 and 15; prior intravenous thrombolysis was 62%, 83%, 78% and 56%; onset to reperfusion time was 289, 285, 267 and 249 min; successful recanalization (mTICI score 2b or 3) was 86%, 71%, 59% and 83%; functional independence at 3 months was 45.5% (95% CI: 44-47), 46.0% (42-50), 38% (35-41) and 37% (35-41), respectively; death was 19.2% (19-21), 15.3% (12.7-18.4), 29.2% (27-32) and 28.6% (27-31); and SICH was 3.6% (3-4), 4.4% (3.0-6.4), 5.8% (4.7-7.1) and not available. CONCLUSION: Thrombectomy in routine clinical use registered in the SITS-ISTR showed safety and outcomes comparable to RCTs, and better functional outcomes and lower mortality than previous national registry studies.

Low-Energy Nuclear Excitations along the α-Decay Chains of Superheavy

We present the first triaxial beyond-mean-field study of the excitation spectra of even-even superheavy nuclei. As representative examples, we have chosen the members of the α-decay chains of ^{292}Lv and ^{294}Og, the heaviest even-even nuclei which have been synthesized so far using ^{48}Ca-induced fusion-evaporation reactions. In our calculations, the effective finite-range density-dependent Gogny force is used and the angular-momentum and particle-number symmetries are restored. Configuration-mixing calculations are performed to determine ground- and excited-state deformations and to establish the collective band structures of these nuclei. Rapidly varying characteristics are predicted for the members of both decay chains, which are further accentuated when compared to the predictions of simple collective models. Based on the present calculations, the prospect of observing α-decay fine structures in future experiments is discussed.

Spectroscopy along Flerovium Decay Chains: Discovery of

A nuclear spectroscopy experiment was conducted to study α-decay chains stemming from isotopes of flerovium (element Z=114). An upgraded TASISpec decay station was placed behind the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany. The fusion-evaporation reactions ^{48}Ca+^{242}Pu and ^{48}Ca+^{244}Pu provided a total of 32 flerovium-candidate decay chains, of which two and eleven were firmly assigned to ^{286}Fl and ^{288}Fl, respectively. A prompt coincidence between a 9.60(1)-MeV α particle event and a 0.36(1)-MeV conversion electron marked the first observation of an excited state in an even-even isotope of the heaviest man-made elements, namely ^{282}Cn. Spectroscopy of ^{288}Fl decay chains fixed Q_{α}=10.06(1) MeV. In one case, a Q_{α}=9.46(1)-MeV decay from ^{284}Cn into ^{280}Ds was observed, with ^{280}Ds fissioning after only 518 µs. The impact of these findings, aggregated with existing data on decay chains of ^{286,288}Fl, on the size of an anticipated shell gap at proton number Z=114 is discussed in light of predictions from two beyond-mean-field calculations, which take into account triaxial deformation.

Predominance of Triaxial Shapes in Transitional Super-Heavy Nuclei: Ground-State Deformation and Shape Coexistence along the Flerovium (Z=114) Chain of Isotopes.

We present the first triaxial beyond-mean-field study of even-even super-heavy nuclei. Calculations for the even Flerovium isotopes towards the supposed N=184 neutron shell closure were performed using the effective finite-range density-dependent Gogny force. They include the restoration of the particle-number and angular-momentum symmetries and the mixing of different shapes using the generator coordinate method. The importance of the γ degree of freedom is highlighted by comparing the triaxial to axial-symmetric calculations performed within the same framework. For the three even Fl isotopes between the prolate ^{288}Fl and the oblate ^{296}Fl triaxial ground-state shapes are predicted, whereas axial-symmetric calculations suggest a sharp prolate-oblate shape transition between ^{290}Fl and ^{292}Fl. A novel type of shape coexistence, namely, that between two different triaxial shapes, is predicted to occur in ^{290}Fl. Finally, the existence of a neutron shell closure at N=184 is confirmed, while no evidence is found for Z=114 being a proton magic number.

Use of intracranial stent as rescue therapy after mechanical thrombectomy failure-9-year experience in a comprehensive stroke centre.

PURPOSE: There is no established rescue treatment in patients with mechanical thrombectomy (MT) failure. Our aim is to analyse whether the use of an intracranial stent improves prognosis in these patients. METHODS: Retrospective analysis of a prospective cohort of patients with ischemic stroke due to middle cerebral artery occlusion (MCA) or distal intracranial carotid artery (ICA) occlusion, from September 2009 to April 2019 in our comprehensive stroke care centre. Patients with MT failure were identified and dichotomized into two groups according to whether or not an intracranial stent was implanted. We analysed clinical outcomes in both groups. RESULTS: There was MT failure in 60 patients (14%) of the 433 with large vessel occlusion in distal ICA and proximal MCA. A stent was placed in 20 of them (33.3%). Compared to patients without rescue stenting, they showed better rates of independence at 3 months (mRS ≤ 2) 45% vs 2.5% (p < 0.001) and lower mortality 15% vs 50% (p = 0.009), maintaining statistical significance after multivariate analysis, without a significant increase of the rate of symptomatic intracranial haemorrhage (p = 0.209). CONCLUSION: Placement of an intracranial stent as rescue therapy after MT failure was associated with better clinical outcome without significant increase in haemorrhagic complications. We believe that this procedure should be appraised in these patients.

Galectin-3 Is Associated with Cardiovascular Events in Post-Acute Coronary Syndrome Patients with Type-2 Diabetes.

INTRODUCTION: Type-2 diabetes mellitus (T2DM) is associated with early and severe atherosclerosis. However, few biomarkers can predict cardiovascular events in this population. METHODS: We followed 964 patients with coronary artery disease (CAD), assessing plasma levels of galectin-3, monocyte chemoattractant protein-1 (MCP-1), and N-terminal fragment of brain natriuretic peptide (NT-proBNP) at baseline. The secondary outcomes were acute ischemia and heart failure or death. The primary outcome was the combination of the secondary outcomes. RESULTS: Two hundred thirty-two patients had T2DM. Patients with T2DM showed higher MCP-1 (144 (113-195) vs. 133 (105-173) pg/mL, p = 0.006) and galectin-3 (8.3 (6.5-10.5) vs. 7.8 (5.9-9.8) ng/mL, p = 0.049) levels as compared to patients without diabetes. Median follow-up was 5.39 years (2.81-6.92). Galectin-3 levels were associated with increased risk of the primary outcome in T2DM patients (Hazard ratio (HR) 1.57 (1.07-2.30); p = 0.022), along with a history of cerebrovascular events. Treatment with clopidogrel was associated with lower risk. In contrast, NT-proBNP and MCP-1, but not galectin-3, were related to increased risk of the event in nondiabetic patients (HR 1.21 (1.04-1.42); p = 0.017 and HR 1.23 (1.05-1.44); p = 0.012, respectively), along with male sex and age. Galectin-3 was also the only biomarker associated with the development of acute ischemic events and heart failure or death in T2DM patients, while, in nondiabetics, MCP-1 and NT-proBNP, respectively, were related to these events. CONCLUSION: In CAD patients, galectin-3 plasma levels are associated with cardiovascular events in patients with T2DM, and MCP-1 and NT-proBNP in those without T2DM.

Predictive and diagnostic biomarkers for gestational diabetes and its associated metabolic and cardiovascular diseases.

Gestational diabetes mellitus (GDM) is defined as the presence of high blood glucose levels with the onset, or detected for the first time during pregnancy, as a result of increased insulin resistance. GDM may be induced by dysregulation of pancreatic ß-cell function and/or by alteration of secreted gestational hormones and peptides related with glucose homeostasis. It may affect one out of five pregnancies, leading to perinatal morbidity and adverse neonatal outcomes, and high risk of chronic metabolic and cardiovascular injuries in both mother and offspring. Currently, GDM diagnosis is based on evaluation of glucose homeostasis at late stages of pregnancy, but increased age and body-weight, and familiar or previous occurrence of GDM, may conditionate this criteria. In addition, an earlier and more specific detection of GDM with associated metabolic and cardiovascular risk could improve GDM development and outcomes. In this sense, 1st-2nd trimester-released biomarkers found in maternal plasma including adipose tissue-derived factors such as adiponectin, visfatin, omentin-1, fatty acid-binding protein-4 and retinol binding-protein-4 have shown correlations with GDM development. Moreover, placenta-related factors such as sex hormone-binding globulin, afamin, fetuin-A, fibroblast growth factors-21/23, ficolin-3 and follistatin, or specific micro-RNAs may participate in GDM progression and be useful for its recognition. Finally, urine-excreted metabolites such as those related with serotonin system, non-polar amino-acids and ketone bodies, may complete a predictive or early-diagnostic panel of biomarkers for GDM.

The neurologist's approach to cerebral infarct and transient ischaemic attack in patients receiving anticoagulant treatment for non-valvular atrial fibrillation: ANITA-FA study.

BACKGROUND AND PURPOSE: The aim of this study was to describe the clinical and epidemiological characteristics of acute ischaemic stroke (AIS) in patients with atrial fibrillation (AF) previously treated with oral anticoagulants (OACs) according to the type of OAC prescribed. Also, to analyze the outcomes of the patients and the therapeutic approach adopted by the neurologist in the acute phase and for secondary prevention. METHODS: We performed a multicenter, observational study based on prospective registries. We included patients with AF treated with OACs admitted for AIS over a 1-year period. Detailed clinical data and functional outcome at 3 months (modified Rankin Scale score) were collected. Patients were divided into two groups according to their pre-AIS anticoagulant therapy: vitamin K antagonists (AIS-VKA) and direct-acting OACs (AIS-DOAC). RESULTS: We recruited 1240 patients (80.4% AIS-VKA and 19.6% AIS-DOAC). In the AIS-DOAC group, transient ischaemic attack was more frequent (18.1% vs. 10.8%; P = 0.001), symptomatic hemorrhagic transformation was less frequent (1.6% vs. 4.6%; P = 0.035) and hospital stay was shorter (median 6 vs. 7 days; P = 0.03). Intravenous thrombolysis was more commonly used in AIS-VKA (9.2% vs. 1.6%; P < 0.001). There were no differences between the groups with respect to mechanical thrombectomy, mortality and modified Rankin Scale score at 3 months. At 3 months, 54% of patients required a DOAC as antithrombotic treatment for secondary prevention. CONCLUSIONS: Patients with AF treated with DOACs who experienced AIS more frequently had transient symptoms (transient ischaemic attack), less symptomatic hemorrhagic transformation and a shorter mean stay than those treated with VKAs. Most patients who had been previously anticoagulated with AIS received long-term treatment with DOACs.

Salud Cardiovascular En Población Migrante Ecuatoriana En Madrid (España). ¿Debemos Preocuparnos? / Cardiovascular Health In An Ecuadorian Migrant Population To Madrid (Spain). Should We Worry?

RESUMEN Antecedentes: La comunidad ecuatoriana es la tercera comunidad extranjera más numerosa en España. Sin embargo, es poco lo que se conoce acerca de su estado de salud cardiovascular (CV) y si los efectos de la migración han causado un detrimento en dicho estado. Métodos: Con el objetivo de conocer la salud CV en una población ecuatoriana de migrantes en Madrid, se realizó un estudio transversal no aleatorizado en el que se incluyeron personas de nacionalidad ecuatoriana, mayores de 25 años, residentes en Madrid desde hace un año o más. Se realizaron encuestas, mediante el uso de cuestionarios previamente validados, para determinar el estado de salud CV de la población, así como el grado de distress psicológico. Resultados: Se incluyeron 165 participantes (68,5% mujeres), con edad promedio de 49 años. El 86,1% de la población estudiada presentó salud cardiovascular pobre y 13,9% intermedia, sin diferencias significativas según el sexo. No hubo individuos que cumplan las 7 variables con valores ideales. Las mujeres presentaron puntuaciones más altas en el cuestionario DASS-21 en comparación a los hombres (p<0,05). Conclusión: En la población migrante ecuatoriana residente en Madrid, más del 85% presentó una salud CV pobre, y ninguno presentó una salud CV ideal. Los factores de riesgo más prevalentes en dicha población fueron pobre actividad física, sobrepeso/obesidad y malos hábitos dietéticos. Se requieren más estudios para identificar la situación real de riesgo CV de la población migrante ecuatoriana. Probablemente, a medio-largo plazo, será necesario implementar políticas de salud especialmente dirigidas a los migrantes.

ABSTRACT Background: The Ecuadorian community is the third largest foreign community in Spain. However, little is known about their cardiovascular (CV) health status and whether the effects of migration have caused a detriment in that state. Methods: With the aim of knowing the CV health in an Ecuadorian population of migrants in Madrid, a non-randomized, cross-sectional study was carried out, which included people of Ecuadorian nationality, older than 25 years, living in Madrid for a year or more. Surveys were conducted through the use of previously validated questionnaires, to determine the health status of the population, as well as the degree of neuro-physiological distress. Results: We included 165 participants (68.5% women), with an average age of 49 years. Of these, 86.1% presented poor cardiovascular health and 13.9% intermediate, without significant differences according to sex. There were no individuals that met the 7 variables consistent with and ideal CV status. Women had higher scores on the DASS-21 questionnaire compared to men (p <0.05). Conclusion: In the Ecuadorian migrant population living in Madrid, more than 85% had poor CV health, and none had an ideal CV health. Most prevalent risk factors in this population were poor physical activity, overweight/obesity and poor dietary habits. More studies are required to identify the real situation of CV risk in the Ecuadorian migrant population. Probably, in the medium-long term, it will be necessary to implement health policies especially addressed to migrants.

Factores pronósticos y análisis de la mortalidad de las hemorragias cerebrales asociadas a anticoagulantes orales antagonistas de la vitamina K. Resultados del Estudio TAC Registry / Prognostic factors and analysis of mortality due to brain haemorrhages associated with vitamin K antagonist oral anticoagulants. Results from the TAC registry

INTRODUCCIÓN: La hemorragia intracraneal (HIC) en pacientes tratados con anticoagulantes orales antagonistas de la vitamina K (AVK) es una complicación grave y frecuentemente letal; en este trabajo estudiamos las características clínicas y los factores que se relacionan con la mortalidad en este grupo de pacientes. MÉTODOS: Realizamos un estudio observacional, multicéntrico y retrospectivo, de ámbito nacional, basado en registros prospectivos de pacientes con ictus. Se incluyó a los pacientes ingresados en servicios de Neurología durante un período de un año y que cumplieran los criterios de inclusión: pacientes mayores de 18 años con HIC que estuvieran en tratamiento con AVK y que ingresaron durante el periodo de estudio. Se analizaron las variables clínicas y radiológicas y su evolución a 3 meses. RESULTADOS: Incluimos a 235 pacientes provenientes de 21 hospitales. La mortalidad a los 90 días fue del 42,6%. En el modelo bivariante los factores asociados con defunción fueron: mediana en la puntuación de la escala NIHSS al ingreso (5 (RIQ = 9) vs. 17 (RIQ = 14) puntos, p < 0,01) y la presencia de una hemorragia hemisférica extensa (4,9% vs. 35%, p < 0,01; chi2). Las hemorragias hemisféricas extensas, además de ser las más letales, también presentaron el tiempo más corto hasta el fallecimiento (media 16,5 días; IC del 95%, 7,1-26). Realizamos un modelo de regresión logística que evidenció que solo la NIHSS basal predijo de forma independiente el fallecimiento (odds ratio = 1,13 (IC del 95%, 1,0-1,17) por cada punto en la escala). CONCLUSIÓN: La HIC en pacientes tratados con AVK conlleva una elevada mortalidad asociada principal e independientemente con la situación clínica al inicio del ictus

INTRODUCTION: Intracranial haemorrhages (ICH) represent a severe and frequently lethal complication in patients treated with vitamin K antagonists (VKA). The purpose of our study is to describe the factors and clinical features associated with mortality in these patients. METHODS: We conducted an observational, retrospective, multi-centre study based on prospective stroke registries in Spain. We included all patients admitted to neurology departments during a one-year period who met the following inclusion criteria: being 18 or older, having a diagnosis of ICH, and receiving VKA. Clinical and radiological parameters and 3-month outcomes were analysed. RESULTS: A total of 235 patients from 21 hospitals were included. Mortality rate at 90 days was 42.6%. Bivariate analysis showed a significant association between death and the following factors: median NIHSS score at admission (5 (IQR = 9) vs 17 (IQR = 14) points, P < .01) and presence of an extensive hemispheric haemorrhage (4.9% vs 35%, P < .01; chi2). Extensive hemispheric haemorrhages, in addition to being the most lethal type, were associated with a shorter time to death (mean of 16.5 days; 95% CI: 7.1-26). A logistic regression model showed that only baseline NIHSS scores independently predicted death (odds ratio = 1.13 (95% CI: 1.08-1.17) for each point in the scale). CONCLUSION: ICH in patients treated with VKA is associated with high mortality rates; mortality in these patients is mainly and independently associated with the clinical situation at stroke onset

Sitagliptin improved glucose assimilation in detriment of fatty-acid utilization in experimental type-II diabetes: role of GLP-1 isoforms in Glut4 receptor trafficking.

BACKGROUND: The distribution of glucose and fatty-acid transporters in the heart is crucial for energy consecution and myocardial function. In this sense, the glucagon-like peptide-1 (GLP-1) enhancer, sitagliptin, improves glucose homeostasis but it could also trigger direct cardioprotective actions, including regulation of energy substrate utilization. METHODS: Type-II diabetic GK (Goto-Kakizaki), sitagliptin-treated GK (10 mg/kg/day) and wistar rats (n = 10, each) underwent echocardiographic evaluation, and positron emission tomography scanning for [18F]-2-fluoro-2-deoxy-D-glucose (18FDG). Hearts and plasma were isolated for biochemical approaches. Cultured cardiomyocytes were examined for receptor distribution after incretin stimulation in high fatty acid or high glucose media. RESULTS: Untreated GK rats exhibited hyperglycemia, hyperlipidemia, insulin resistance, and plasma GLP-1 reduction. Moreover, GK myocardium decreased 18FDG assimilation and diastolic dysfunction. However, sitagliptin improved hyperglycemia, insulin resistance, and GLP-1 levels, and additionally, enhanced 18FDG uptake and diastolic function. Sitagliptin also stimulated the sarcolemmal translocation of the glucose transporter-4 (Glut4), in detriment of the fatty acyl translocase (FAT)/CD36. In fact, Glut4 mRNA expression and sarcolemmal translocation were also increased after GLP-1 stimulation in high-fatty acid incubated cardiomyocytes. PI3K/Akt and AMPKα were involved in this response. Intriguingly, the GLP-1 degradation metabolite, GLP-1(9-36), showed similar effects. CONCLUSIONS: Besides of its anti-hyperglycemic effect, sitagliptin-enhanced GLP-1 may ameliorate diastolic dysfunction in type-II diabetes by shifting fatty acid to glucose utilization in the cardiomyocyte, and thus, improving cardiac efficiency and reducing lipolysis.

CONCLUSION: ICH in patients treated with VKA is associated with high mortality rates; mortality in these patients is mainly and independently associated with the clinical situation at stroke onset.

Sun exposure influences the prognostic power of components of mineral metabolism in patients with coronary artery disease.

BACKGROUND AND AIM: Calcidiol (vitamin D metabolite) plasma levels vary with sun exposure (SE). However, it is not known if SE influences its prognostic ability. We have studied the effect of SE on plasma levels of the components of mineral metabolism (calcidiol, fibroblast growth factor-23 [FGF-23], parathormone [PTH], and phosphate [P]) and on their prognostic value in patients with coronary artery disease (CAD). METHODS AND RESULTS: We studied prospectively 704 patients with stable CAD. Clinical variables and baseline calcidiol, FGF-23, PTH, and P plasma levels were assessed. We divided the population in two subgroups, according to the period of plasma extraction: High SE (HSE) (April-September) and low SE (LSE) (October-March). The outcome was the development of acute ischemic events (acute coronary syndrome, stroke, or transient ischemic attack), heart failure, or death. Mean follow-up was 2.15 ± 0.99 years. Calcidiol and P levels were higher in HSE group. In the whole population, calcidiol (HR = 0.84 for each 5 ng/ml increase, 95% CI = 0.71-0.99; p = 0.038) and FGF-23 (HR = 1.14 for each 100 RU/ml increase, 95% CI = 1.05-1.23; p = 0.009) were predictors of the outcome, along with age, hypertension, body-mass index, peripheral artery disease, and P levels. In the LSE subgroup, calcidiol (HR = 0.75; 95% CI = 0.57-0.99; p = 0.034) and FGF-23 (HR = 1.34; 95% CI = 1.13-1.58; p = 0.003) remained as predictors of the outcome. In the HSE group calcidiol and FGF-23 had not independent prognostic value. CONCLUSIONS: In patients with stable CAD, low calcidiol and high FGF-23 plasma levels predict an adverse prognosis only when the sample is obtained during the months with LSE. SE should be taken into account in the clinical practice.

Regulation of visceral and epicardial adipose tissue for preventing cardiovascular injuries associated to obesity and diabetes.

Nowadays, obesity is seriously increasing in most of the populations all over the world, and is associated with the development and progression of high-mortality diseases such as type-2 diabetes mellitus (T2DM) and its subsequent cardiovascular pathologies. Recent data suggest that both body fat distribution and adipocyte phenotype, can be more determinant for fatal outcomes in obese patients than increased general adiposity. In particular, visceral adiposity is significantly linked to long term alterations on different cardiac structures, and in developed forms of myocardial diseases such as hypertensive and ischaemic heart diseases, and diabetic cardiomyopathy. Interestingly, this depot may be also related to epicardial fat accumulation through secretion of lipids, adipokines, and pro-inflammatory and oxidative factors from adipocytes. Thus, visceral adiposity and its white single-lipid-like adipocytes, are risk factors for different forms of heart disease and heart failure, mainly in higher degree obese subjects. However, under specific stimuli, some of these adipocytes can transdifferentiate to brown multi-mitochondrial-like adipocytes with anti-inflammatory and anti-apoptotic proprieties. Accordingly, in order to improve potential cardiovascular abnormalities in obese and T2DM patients, several therapeutic strategies have been addressed to modulate the visceral and epicardial fat volume and phenotypes. In addition to lifestyle modifications, specific genetic manipulations in adipose tissue and administration of PPARγ agonists or statins, have improved fat volume and phenotype, and cardiovascular failures. Furthermore, incretin stimulation reduced visceral and epicardial fat thickness whereas increased formation of brown adipocytes, alleviating insulin resistance and associated cardiovascular pathologies.

Unnecessary overuse. Study of "inadvisable practices" for patients with atrial fibrillation. / Sobreutilización innecesaria. Estudio de los «no hacer¼ en pacientes con fibrilación auricular.

OBJECTIVE: To identify overuse (diagnostic, therapeutic and self-care practices that represent risks that outweigh the potential benefits) in patients with atrial fibrillation. METHOD: The study was based on qualitative research techniques. Using the "Metaplan" technique, we identified and ordered potentially inappropriate, ineffective and inefficient practices. By means of a consensus conference, we then established a number of "inadvisable practice" measures (relatively common practices that should be eliminated based on the scientific evidence or clinical experience). Professionals from the specialties of cardiology, haematology, neurology, internal medicine, family medicine and nursing participated in the consensus. RESULTS: We developed a catalogue of 19 "inadvisable practices" related to the diagnosis, treatment and care of anticoagulated patients that were inappropriate, had questionable effectiveness or were ineffective, as well as 13 beliefs or behaviours for anticoagulated patients that could result in injury or were useless or inefficient. CONCLUSION: The "inadvisable practices" approach helps identify practices that represent greater risks than benefits for patients. It seems appropriate to include algorithms in the clinical decision-making support systems that consider this information for the diagnosis, treatment and for home care. For this last case, recommendations have also been prepared that define specific contents for the healthcare education of these patients.

Diagnostic approaches for diabetic cardiomyopathy.

Diabetic cardiomyopathy (DCM) is a cardiac dysfunction which affects approximately 12% of diabetic patients, leading to overt heart failure and death. However, there is not an efficient and specific methodology for DCM diagnosis, possibly because molecular mechanisms are not fully elucidated, and it remains asymptomatic for many years. Also, DCM frequently coexists with other comorbidities such as hypertension, obesity, dyslipidemia, and vasculopathies. Thus, human DCM is not specifically identified after heart failure is established. In this sense, echocardiography has been traditionally considered the gold standard imaging test to evaluate the presence of cardiac dysfunction, although other techniques may cover earlier DCM detection by quantification of altered myocardial metabolism and strain. In this sense, Phase-Magnetic Resonance Imaging and 2D/3D-Speckle Tracking Echocardiography may potentially diagnose and stratify diabetic patients. Additionally, this information could be completed with a quantification of specific plasma biomarkers related to related to initial stages of the disease. Cardiotrophin-1, activin A, insulin-like growth factor binding protein-7 (IGFBP-7) and Heart fatty-acid binding protein have demonstrated a stable positive correlation with cardiac hypertrophy, contractibility and steatosis responses. Thus, we suggest a combination of minimally-invasive diagnosis tools for human DCM recognition based on imaging techniques and measurements of related plasma biomarkers.

Association of ficolin-3 with abdominal aortic aneurysm presence and progression.

Essentials Abdominal aortic aneurysm (AAA) is asymptomatic and its evolution unpredictable. To find novel potential biomarkers of AAA, microvesicles are an excellent source of biomarkers. Ficolin-3 is increased in microvesicles obtained from activated platelets and AAA tissue. Increased ficolin-3 plasma levels are associated with AAA presence and progression. SUMMARY: Background Abdominal aortic aneurysm (AAA) patients are usually asymptomatic and AAA evolution is unpredictable. Ficolin-3, mainly synthesized by the liver, is a molecule of the lectin complement-activation pathway involved in AAA pathophysiology. Objectives To define extra-hepatic sources of ficolin-3 in AAA and investigate the role of ficolin-3 as a biomarker of the presence and progression of AAA. Methods Microvesicles (exosomes and microparticles) were isolated from culture-conditioned medium of ADP-activated platelets, as well as from AAA tissue-conditioned medium (thrombus and wall). Ficolin-3 levels were analyzed by western-blot, real-time PCR, immunohistochemistry and ELISA. Results Increased ficolin-3 levels were observed in microvesicles isolated from activated platelets. Similarly, microvesicles released from AAA tissue display increased ficolin-3 levels as compared with those from healthy tissue. Moreover, ficolin-3 mRNA levels in the AAA wall were greatly increased compared with healthy aortic walls. Immunohistochemistry of AAA tissue demonstrated increased ficolin-3, whereas little staining was present in healthy walls. Finally, increased ficolin-3 levels were observed in AAA patients' plasma (n = 478) compared with control plasma (n = 176), which persisted after adjustment for risk factors (adjusted odds ratio [OR], 5.29; 95% confidence interval [CI], 3.27, 8.57)]. Moreover, a positive association of ficolin-3 with aortic diameter (Rho, 0.25) and need for surgical repair was observed, also after adjustment for potential confounding factors (adjusted hazard ratio, 1.55; 95% CI, 1.11, 2.15). Conclusions In addition to its hepatic expression, ficolin-3 may be released into the extracellular medium via microvesicles, by both activated cells and pathological AAA tissue. Ficolin-3 plasma levels are associated with the presence and progression of AAA, suggesting its potential role as a biomarker of AAA.
