Effects of treatment with monacolin K, berberine and coenzyme Q10 on lipid metabolism in patients with moderate cardiovascular risk.

OBJECTIVE: The use of nutritional supplements to treat hypercholesterolemia is gradually increasing, however further studies on their efficacy and safety are required. PATIENTS AND METHODS: The present clinical trial included patients with moderate hypercholesterolemia and cardiovascular risk who were treated either with a nutraceutical preparation containing 3.75mg of monacolin K, 515mg of berberine and 50mg of coenzyme Q10 per tablet (Lipok®) or with a placebo. The clinical and laboratory variables were analyzed at baseline and at three and six months. None of the patients was diabetic, and none was being treated with lipid-lowering drugs or with any other nutritional supplements affecting lipid metabolism. RESULTS: In patients of the intervention group and of the placebo group, baseline LDL-C was 134.7mg/dL (14.4) and 138.7mg/dL (15.2), respectively. At three months after treatment start, LDL-C had decreased by 26.1mg/dL (-32.4 to 19.7) and increased by 4.5mg/dL (-1.5 to 10.5) in the respective groups. In the intervention group, a similar decrease in non-HDL-C and total cholesterol was observed, while no significant changes were observed in either group for HDL-C, triglycerides and lipoprotein(a). A good tolerance and safety profile was observed. CONCLUSION: In conclusion, this study demonstrates that the combination of monacolin K, berberine and coenzyme Q10 is effective and safe for treating hypercholesterolemia in patients with a moderate degree of excess LDL-C and cardiovascular risk.

[Early detection and stability of diagnosis in autism spectrum disorders]. / Deteccion precoz y estabilidad en el diagnostico en los trastornos del espectro autista.

INTRODUCTION: Early intervention for children with an autism spectrum disorder (ASD) depends on early and reliable detection. In general, diagnosis is stable, but evidence shows the need to go deeper into the factors that influence this stability. PATIENTS AND METHODS: A sample of 142 children with ASD (118 boys and 24 girls) with a median of 33 months of age and an interquartile range of 12 in the first evaluation. In the follow-up the median was 47 months and an interquartile range of 29. The following tests were applied to evaluate the children: Merrill-Palmer Scale-R, Leitter-R, WIPPSI-III, WISC-R and WISC-IV; as well as Vineland Scale and ADOS-G, based on clinical diagnosis to DSM-IV-R and DSM-5. For the evaluation of the diagnostic stability, contingency tables were performed for diagnostic assessments based on clinical judgment and the results of the ADOS-G. Repeated measures ANOVA was used to analyze the differences between measures of cognitive functioning, adaptive behavior and diagnosis. RESULTS: The clinical diagnosis based on DSM-IV-TR, DSM-5 and clinical judgment remains stable over time in 96% of cases. If the diagnostic stability is measured based on the results of ADOS-G (n = 30), 87% of cases diagnosed maintained the diagnosis. The ANOVA showed statistically significant differences for measures of within-subject factors and global social age, but not for diagnosis. CONCLUSION: The diagnostic stability can be improved by utilizing clinical judgment and the participation of a multidisciplinary team.

TITLE: Deteccion precoz y estabilidad en el diagnostico en los trastornos del espectro autista.Introduccion. La intervencion temprana en los niños con un trastorno del espectro autista (TEA) depende de una deteccion precoz y fiable. Aunque de manera general se habla de un diagnostico estable, se ha evidenciado la necesidad de profundizar mas en los factores que influyen en dicha estabilidad. Pacientes y metodos. Los participantes de la muestra fueron 142 menores con TEA (118 varones y 24 mujeres), con una mediana de 33 meses y un recorrido intercuartilico de 12 en la primera evaluacion, y con una mediana de 47 meses y un recorrido intercuartilico de 29 en el seguimiento. Los diagnosticos se realizaron con las siguientes pruebas: escala Merrill-Palmer revisada, escala de Leiter revisada, escala de inteligencia de Wechsler para preescolar y primaria III y escala de inteligencia de Wechsler para niños revisada y IV; ademas de la escala Vineland y la escala de observacion diagnostica del autismo generica (ADOS-G), basandose el diagnostico clinico en los criterios diagnosticos del Manual diagnostico y estadistico de los trastornos mentales, cuarta edicion, texto revisado (DSM-IV-TR), y quinta edicion (DSM-5). Para la evaluacion de la estabilidad diagnostica, se realizaron tablas de contingencia para las valoraciones del diagnostico en funcion del juicio clinico y los resultados de la ADOS-G. Resultados. El diagnostico clinico basado en los criterios del DSM-IV-TR, el DSM-5 y el juicio clinico se mantiene estable a traves del tiempo en un 96% de los casos. Si se valora la estabilidad diagnostica teniendo en cuenta los resultados del ADOS-G (n = 30), el 87% de los casos mantiene el diagnostico. El ANOVA muestra diferencias estadisticamente significativas para las medidas del factor intrasujeto del cociente intelectual y la edad social global, pero no para el diagnostico. Conclusiones. La estabilidad diagnostica se beneficia de un uso informado del criterio clinico y de la participacion de un equipo multidisciplinar.

Las emergencias extrahospitalarias ante la cultura de seguridad / Out of hospital emergencies towards a safety culture

Objetivos. Estudiar el grado de cultura de seguridad (CS) de los profesionales en el ámbito de un servicio de urgencias extrahospitalarias. Analizar las dimensiones que reciben puntuaciones inferiores, con el fin de establecer futuras estrategias de actuación. Material y métodos. Estudio observacional, descriptivo, transversal en el que se distribuyó el cuestionario de la Agency for Healthcare Research and Quality (AHRQ) al universo muestral de los profesionales sanitarios que trabajan en las unidades de soporte vital avanzado del 061 de Aragón, durante el mes de agosto de 2013. Resultados. Se analizaron 80 cuestionarios (tasa de respuesta 55,55%). Principales fortalezas: adecuada dotación de personal (96%), buen clima laboral (89%), apoyo de superiores inmediatos (77%), trabajo en equipo (74%) y ambiente no punitivo hacia los eventos adversos (68%). Áreas de mejora: insuficiente formación en seguridad del paciente (53%), ausencia de feedback (50%). Conclusiones. Las oportunidades de mejora detectadas se centran en la formación de los profesionales, con el fin de procurar una asistencia más segura, extendiendo al mismo tiempo la cultura de seguridad. Así mismo se considera necesaria la puesta en marcha de un sistema de notificación y registro de eventos adversos en nuestro servicio (AU)

Objectives. The aim of this study is to measure the degree of safety culture (CS) among healthcare professional workers of an out-of-hospital Emergency Medical Service. Most patient safety studies have been conducted in relation to the hospital rather than pre-hospital Emergency Medical Services. The objective is to analyze the dimensions with lower scores in order to plan futures strategies. Material and methods. A descriptive study using the AHRQ (Agency for Healthcare Research and Quality) questionnaire. The questionnaire was delivered to all healthcare professionals workers of 061 Advanced Life Support Units of Aragón, during the month of August 2013. Results. The response rate was 55%. Main strengths detected: an adequate number of staff (96%), good working conditions (89%), tasks supported from immediate superior (77%), teamwork climate (74%), and non-punitive environment to report adverse events (68%). Areas for improvement: insufficient training in patient safety (53%) and lack of feedback of incidents reported (50%). Conclusions. The opportunities for improvement identified focus on the training of professionals in order to ensure safer care, while extending the safety culture. Also, the implementation of a system of notification and registration of adverse events in the service is deemed necessary (AU)

Troglitazone, but not rosiglitazone, inhibits Na/H exchange activity and proliferation of macrovascular endothelial cells.

Diabetes is associated with a high level of mortality due to cardiovascular disease resulting from accelerated coronary artery atherosclerosis. A current focus for investigation of atherosclerotic mechanisms is the vascular endothelium since physical or functional injury may represent an initiating step for atherogenesis. Thiazolidinediones (TZDs) are the newest class of drugs for the treatment of insulin resistance and its metabolic consequences; they are peroxisome proliferator-activating receptor (PPAR)-gamma ligands that act as insulin-sensitizing agents. We are interested in the contribution of direct vascular actions to the clinical utility of these agents. We investigated the effect troglitazone and rosiglitazone on endothelial cell proliferation in low- and high-glucose media and further explored their action on the ubiquitous membrane transport system, the Na/H exchanger (NHE), which has been implicated in regulating the growth of vascular cells. Experiments were conducted in cultured bovine aortic endothelial cells (BAECs). Cell proliferation was assessed by cell counting, and NHE activity was determined in cells loaded with the pH-sensitive fluorescent dye, 2',7'-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein, acetoxymethyl ester (BCECF-AM). Troglitazone caused a dose-dependent inhibition of endothelial cell proliferation with approximately 50% inhibition at 10 microM. Troglitazone inhibited endothelial cell proliferation with similar potency under low- (5 mM) and high-glucose (25 mM) concentrations. Rosiglitazone had no significant effect on endothelial cell proliferation at concentrations of up to 100 microM under low- or high-glucose concentrations. The NHE inhibitor, 3-metlylsulfonyl-4-piperidinobenzoyl guanidine (HOE 694), caused dose dependent inhibition of BAEC proliferation, which was independent of the media glucose concentration. Acute exposure of cells to troglitazone (10 microM) and rosiglitazone (30 microM) during recovery from acidosis showed slight but significant (P<.05) inhibition of NHE activity by troglitazone, but no significant (P>.05) effect by rosiglitazone. Exposure of cells to either drug for 24 h revealed no chronic regulation of NHE activity. Our data demonstrate that troglitazone has similar actions in endothelial cells as in vascular smooth muscle. The absence of rosiglitazone effects, a more potent PPAR-gamma activator, suggests that the observed actions of troglitazone may be at least partially independent of PPAR-gamma. The effects of troglitazone and rosiglitazone on endothelial cell proliferation and NHE activity, although contrasting, are consistent with a central signalling role of this transporter in cell proliferation.
