Abstract

International audience; BACKGROUND: The use of intensive lipid-lowering therapy by means of statin medications is recommended after transient ischemic attack (TIA) and ischemic stroke of atherosclerotic origin. The target level for low-density lipoprotein (LDL) cholesterol to reduce cardiovascular events after stroke has not been well studied. METHODS: In this parallel-group trial conducted in France and South Korea, we randomly assigned patients with ischemic stroke in the previous 3 months or a TIA within the previous 15 days to a target LDL cholesterol level of less than 70 mg per deciliter (1.8 mmol per liter) (lower-target group) or to a target range of 90 mg to 110 mg per deciliter (2.3 to 2.8 mmol per liter) (higher-target group). All the patients had evidence of cerebrovascular or coronary-artery atherosclerosis and received a statin, ezetimibe, or both. The composite primary end point of major cardiovascular events included ischemic stroke, myocardial infarction, new symptoms leading to urgent coronary or carotid revascularization, or death from cardiovascular causes. RESULTS: A total of 2860 patients were enrolled and followed for a median of 3.5 years; 1430 were assigned to each LDL cholesterol target group. The mean LDL cholesterol level at baseline was 135 mg per deciliter (3.5 mmol per liter), and the mean achieved LDL cholesterol level was 65 mg per deciliter (1.7 mmol per liter) in the lower-target group and 96 mg per deciliter (2.5 mmol per liter) in the higher-target group. The trial was stopped for administrative reasons after 277 of an anticipated 385 end-point events had occurred. The composite primary end point occurred in 121 patients (8.5%) in the lower-target group and in 156 (10.9%) in the higher-target group (adjusted hazard ratio, 0.78; 95% confidence interval, 0.61 to 0.98; P = 0.04). The incidence of intracranial hemorrhage and newly diagnosed diabetes did not differ significantly between the two groups. CONCLUSIONS: After an ischemic stroke or TIA with evidence of atherosclerosis, patients who had a target LDL cholesterol level of less than 70 mg per deciliter had a lower risk of subsequent cardiovascular events than those who had a target range of 90 mg to 110 mg per deciliter.

Abstract

Short QT syndrome, one of the most lethal entities associated with sudden cardiac death, is a rare genetic disease characterized by short QT intervals detected by electrocardiogram. Several genetic variants are causally linked to the disease, but there has yet to be a comprehensive analysis of variants among patients with short QT syndrome. To fill this gap, we performed an exhaustive study of variants currently catalogued as deleterious in short QT syndrome according to the American College of Medical Genetics and Genomics and the Association for Molecular Pathology. Analysis of the 32 variants described in the literature determined that only nine (28.12%) have a conclusive pathogenic role. All definitively pathogenic variants are located in KCNQ1, KCNH2, or KCNJ2; three genes encoding potassium channels. Other variants located in genes encoding calcium or sodium channels are associated with electrical alterations concomitant with shortened QT intervals but do not guarantee a diagnosis of short QT syndrome. We recommend caution regarding previously reported variants classified as pathogenic. An exhaustive re-analysis is necessary to clarify the role of each variant before routinely translating genetic findings to the clinical setting.

5. Sudden Arrhythmic Death During Exercise: A Post-Mortem Genetic Analysis

Abstract

BACKGROUND: Sudden cardiac death is a natural and unexpected death that occurs within 1 h of the first symptom. Most sudden cardiac deaths occur during exercise, mostly as a result of myocardial infarction. After autopsy, some cases, especially in the young, are diagnosed as cardiomyopathies or remain without a conclusive cause of death. In both situations, genetic alterations may explain the arrhythmia. OBJECTIVE: Our aim was to identify a genetic predisposition to sudden cardiac death in a cohort of post-mortem cases of individuals who died during exercise, with a structurally normal heart, and were classified as arrhythmogenic death. METHODS: We analyzed a cohort of 52 post-mortem samples from individuals

Abstract

Los extractos foliares (EF) son utilizados como complemento nutricional en países como Nicaragua y Tanzania. Se evaluaron hojas y EF de yuca, fríjol, batata y alfalfa, y se cuantificó los componentes nutricionales, antinutricionales y biodisponibilidad por métodos in vitro. En promedio (DE), el EF de fríjol tiene una elevada concentración de hierro (1006,23 (8,49) mg/kg); el EF de yuca tiene alta concentración de zinc (110,65 (6,72) mg/ kg) y proteína soluble (34,23 (3,81) g/kg). Así mismo, la digestibilidad in vitro de proteína en los EFs de yuca, fríjol y alfalfa fueron superiores a 71,18%; hierro dializable in vitro menor a 2,29%; la relación molar fitato:zinc inferior a 0,08 y la bioaccesibilidad all-trans-β -caroteno superior a 23,85%. Estos valores sugieren una alta asimilación de proteína, zinc y all-trans-β -caroteno, y una baja asimilabilidad de hierro. Los EFs pueden ser una alternativa nutricional en la alimentación en países que carecen de diversificación alimentaria.

7. Ruthenium oxide/carbon composites having a microporous carbon or a mesoporous carbon as support. A comparative study as supercapacitor electrodes

Abstract

Composites have been prepared by depositing nanoparticles of RuO2.xH2O (1-5 nm) on two carbons: a microporous carbon (1.3 nm of pore size) and a mesoporous carbon (11 nm of pore size). The composites have been obtained by two ways: (i) way A consisting of an accumulative impregnation treatment of the carbons with RuCl3.0.5H2O solution, and (ii) way B consisting of a impregnation of the carbons with Ru(acac)3 vapour. The way B leads to supported RuO2.xH2O particles that appear more crystalline and more heterogeneous in size than those obtained by way A. Specific surface area and specific capacitance of the composites have been measured. The two magnitudes, which are analysed as a function of the RuO2 content, show very different dependences for the composites derived from the two carbons. They are discussed on the basis of the size of the supported RuO2.xH2O particles in comparison to the size of the carbon pores., Project of reference MAT2005- 01606 is gratefully acknowledged. F. Pico thanks for a contract associated with that project.

8. 3D Nanostructured Silicon Relying on Hard Mask Engineering for High Temperature Annealing (HME-HTA) Processes for Electronic Devices

Abstract

Annealing silicon at high temperatures in hydrogen ambiance has been reported to induce surface diffusion of silicon; in these conditions, adapted 2D arrays of trenches etched in Bulk Si are transformed into buried cavities creating suspended membranes. A 3D nanostructuration of silicon through hard mask engineering and high temperature annealing in hydrogen ambiance is reported. By using a nitride-oxide hard mask stack instead of a sacrificial oxide hard mask for a free surface (maskless) annealing, we open new technological and design possibilities using 2D arrays of various geometry trenches. Implications and potential device applications are discussed.
