In Silico Analysis of the Aromaticity of Some Carbo-Metallabenzenes and Carbo-Dimetallabenzenes (Carbo-mers Proposed from Metallabenzenes).

In the current work, we introduce a novel class of molecules termed carbo-metallabenzenes, and their aromaticity has been comprehensively analyzed. The molecules were strategically designed with the insertion of acetylene (C≡C or C2) units in some selected metallabenzenes. Furthermore, if a second metallic unit is inserted (replacing a sp2 carbon) in the carbo-metallabenzenes rings, a new family of carbo-mers is generated, and this second group has been named as carbo-dimetallabenzenes. The primary objective of this work is to ascertain, through various methodologies, whether these newly proposed molecules retain the aromatic characteristics observed in carbo-benzene. The methodologies employed for bond analysis and aromaticity exploration include the analysis of the molecular orbitals, energy decomposition analysis, electron density of delocalized bonds, magnetically induced current density, and the induced magnetic field (Bind). This study sheds light on that the insertion of the metallic centers reduces the electronic delocalization and their aromaticity is, in some cases, comparable with the electronic delocalization of the inorganic iminobora-borazine and also provides valuable insights into their electronic structure through a multifaceted analysis.

Metallaborazines: To Be or Not To Be Delocalized.

In the current work, the analysis of the electronic delocalization of some metallacycles, based on borazine, was realized by employing magnetic criteria, such as the induced magnetic field and magnetically induced current densities, and electronic criteria, such as adaptative natural density partitioning and the analysis of molecular orbitals. The current metallaborazines were generated from isoelectronic substitutions. The main question is whether the electronic delocalization increases or decreases. The results showed that metal-N bonded borazines could be cataloged as delocalized compounds. On the other hand, the metal-B bonded borazines could be cataloged as nonaromatic (or weak aromatic) compounds based on the results of this analysis.

In Silico Analysis of the Electronic Delocalization in Some Double Fused-Ring Metallabenzenes.

In the current work, some metallabenzenes with one and several fused rings were analyzed in terms of their electronic delocalization. These fused-ring metallabenzenes are known as metallabenzenoids, and their aromatic character is not free of controversy. The systems of the current work were designed from crystallographic data of some synthesized molecules, and their electronic delocalization (aromaticity) was computationally examined in terms of the molecular orbital analysis (Hückel's rule), the induced magnetic field, and ring currents. The computational evidence allows us to understand if these molecules are or are not aromatic compounds.

[Cardiovascular morbimortality reduction after an acute cardiovascular event through multifactorial and intensive cardiovascular risk factors management (MIRVAS project)]. / Reducción de la morbimortalidad cardiovascular tras un episodio cardiovascular agudo mediante el tratamiento intensivo de los factores de riesgo (proyecto MIRVAS).

BACKGROUND AND OBJECTIVE: In spite of publication of many guidelines, management of patients on secondary prevention of cardiovascular disease is still not appropriated. We design a randomized trial, in usual clinical practice conditions, to compare the results in cardiovascular morbimortality of intensive and integral management of cardiovascular risk factors (CVRF) management versus conventional care. PATIENTS AND METHOD: We selected patients discharged between October 2002 and January 2004 who suffered an acute coronary syndrome with or without ST-segment elevation or a stroke, 247 patients that met inclusions criteria were randomized to intensive care of CVRF in a specific Internal Medicine outpatient clinic (n = 121) or usual care according to National Health Service recommendations (n = 126). A year after randomization, the percentage of patients who met CVRF control, treatment received and the number of cardiovascular events (cardiovascular death, acute coronary syndrome with or without ST-segment elevation, stroke, transient ischemic attack, revascularization, lower limb amputation, heart failure admission and sudden death) were revised. RESULTS: CVRF control was greater in patients assigned to intensive care. 74.1% of hypertensive patients assigned to this treatment were controlled vs 41.7% in the usual care group (relative risk [RR] = 1.78; 95% confidence interval [CI], 1.27-2-49); 70.2% of patients had low-densi-tiy lipoprotein cholesterol lower than 100 mg/dl vs 55.8% (RR = 1.26; 95% CI, 1.00-1.58) of patients in usual care group; 93.1% of diabetic patients had glycosylated haemoglobin lower than 7% vs. 57.1% (RR = 1.63; 95% CI, 1.11-2.39) in the usual care group. There were 12 cardiovascular events in the intensive care group vs 35 in the usual care group. CONCLUSIONS: Intensive management of CVRF leads to a better control of them and a reduction of the morbimortality one year after an acute cardiovascular event.

Reducción de la morbimortalidad cardiovascular tras un episodio cardiovascular agudo mediante el tratamiento intensivo de los factores de riesgo (proyecto MIRVAS) / Cardiovascular morbimortality reduction after an acute cardiovascular event through multifactorial and intensive cardiovascular risk factors management (MIRVAS project)

Fundamento y objetivo: A pesar de la publicación de numerosas guías de tratamiento, el seguimiento de los pacientes en prevención secundaria de enfermedad cardiovascular todavía no es el adecuado. Hemos diseñado un ensayo aleatorizado en situación de práctica clínica habitual para evaluar los resultados de un programa de tratamiento integral e intensivo de los factores de riesgo cardiovascular (FRCV) frente al tratamiento convencional en la morbimortalidad cardiovascular. Pacientes y método: Entre octubre de 2002 y enero de 2004 se seleccionó a todos los pacientes dados de alta que habían presentado un síndrome coronario agudo, con o sin elevación del segmento ST, o un ictus. Cumplían los criterios de inclusión un total de 247, que se asignaron aleatoriamente a un tratamiento integral e intensivo de los FRCV en una consulta monográfica atendida por un médico internista (n = 121) o al seguimiento habitual según las recomendaciones del Sistema Nacional de Salud (n = 126). Un año después de la inclusión se comprobó el porcentaje de pacientes que habían alcanzado el control óptimo de cada factor de riesgo, así como el tratamiento recibido y el número de episodios cardiovasculares sucesivos (muerte por causa cardiovascular, síndrome coronario agudo con o sin elevación del segmento ST, ictus, accidente isquémico transitorio, revascularización en cualquier territorio, amputación de extremidades inferiores, ingreso por insuficiencia cardíaca y muerte súbita). Resultados: El control de los FRCV fue superior en el grupo de tratamiento intensivo. Un 74,1% de los pacientes hipertensos asignados a este tratamiento estaban controlados, frente al 41,7% del grupo de tratamiento habitual (riesgo relativo [RR] = 1,78; intervalo de confianza [IC] del 95%, 1,27-2,49); un 70,2% presentaba cifras de colesterol unido a lipoproteínas de baja densidad menores de 100 mg/dl, frente a un 55,8% (RR = 1,26; IC del 95%, 1,00-1,58) del grupo de tratamiento habitual; un 93,1% de los diabéticos presentaba valores de hemoglobina glucosilada inferiores al 7%, frente a un 57,1% (RR = 1,63; IC del 95%, 1,11-2,39) del grupo de tratamiento habitual. Se produjeron 12 episodios cardiovasculares en el grupo de intervención, frente a 35 en el grupo de tratamiento habitual. Conclusiones: El tratamiento intensivo aumenta la proporción de pacientes que alcanzan un control óptimo de los FRCV y reduce la morbimortalidad durante el año siguiente a un episodio cardiovascular

Trauma hepático en el Hospital Regional Simón Bolívar: 1989 - 1993 / Hepatic injury at Hospital Simón Bolívar

En esta investigación se presentan los datos encontrados acerca del trauma hepático en el Hospital Regional Simón Bolívar en el período comprendido entre Marzo de 1989 y Marzo de 1993. El estudio estuvo dirigido a establecer el manejo inicial del paciente con trauma abdominal en el servicio de urgencias, su posterior valoración quirúrgica, los hallazgos intraoperatorios y las complicaciones posteriores al trauma hepático. La información hallada se correlacionó con la revisión hecha sobre el trauma hepático y el protocolo de manejo. No hay clasificación estandar aceptada universalmente para el trauma hepático y las diferencias reportadas entre unas y otras son insignificantes. Se encontró que la morbilidad y la mortalidad tienen una correlación lineal ya que no solamente es el daño del parénquima hepático del que depende el pronóstico sino también de la magnitud de la intervención quirúrgica, hallazgo de heridas asociadas y complicaciones postoperatorias. Las excepciones son el daño de la vena retrohepática que tiene una mortalidad independiente. De ésto concluímos que el manejo del paciente con trauma hepático debe ser integral para asegurar el buen pronóstico
