    Full Text Available Las miopatías inflamatorias son un grupo de enfermedades caracterizadas por debilidad muscular proximal y las causas mayores incluyen la polimiositis (PM, dermatomiositis y miositis por cuerpos de inclusión. Las complicaciones respiratorias son comunes y adquieren importancia por la incidencia sobre el pronóstico. Las tres formas de compromiso frecuentes son la enfermedad pulmonar intersticial, la neumopatía aspirativa y la incapacidad ventilatoria (IV por debilidad de los músculos respiratorios, que en su forma severa es de ocurrencia excepcional. Se presenta una paciente con IV sin compromiso del parénquima pulmonar, que requirió asistencia respiratoria mecánica por 4 meses con «destete» exitoso.The inflammatory diseases of muscle are a group of disorders characterized by proximal muscle weakness. Most cases fall into three major diagnostic categories, polymyositis (PM, dermatomyositis and inclusion body myositis. Respiratory complications are a common feature and are an important cause of morbidity and mortality. The three main types of pulmonary involvement are interstitial lung disease, aspiration pneumonia and ventilatory incapacity (VI due to muscle weakness. There are few reported cases in which mechanical ventilation has been used in patients with PM and VI in absense of lung disease. We present a patient with PM and VI due to muscle weakness who underwent therapy maintenance with mechanical ventilator and was weaned 4 months later.

    2015-05-01

    Full Text Available El asma es una enfermedad frecuente de fisiopatología compleja. El asma severa constituye aproximadamente el 5% de la población de asmáticos, sin embargo representa un desafío clínico y una carga sanitaria importante. Estudios recientes demuestran la existencia de fenotipos en todo el espectro de gravedad. La eosinofilia en esputo y sangre ha demostrado utilidad como marcador de inflamación Th-2 y de respuesta clínica a esteroides, sin embargo aún no existe mucho conocimiento sobre el asma no-eosinofílica. Los tratamientos actuales en asma se enfocan a estrategias de terapia escalonada según severidad, pero en pacientes con asma severa se requiere también del manejo multidisciplinario de las comorbilidades y la determinación del fenotipo, para aplicar terapias más especificas. El desarrollo acelerado de nuevos tratamientos en asma severa como consecuencia del mejor conocimiento de los distintos fenotipos ha ampliado el arsenal terapéutico para un enfrentamiento personalizado y específico en los pacientes con asma severa.

    Full Text Available No existe un concepto definido sobre la influencia de la edad en la mortalidad de la asistencia respiratoria mecánica. Realizamos un trabajo prospectivo-observacional para determinar si la edad es un factor independiente de mortalidad de la asistencia respiratoria mecánica. Se incluyeron 200 pacientes internados en la Unidad de Cuidados Intensivos del Hospital Británico de Buenos Aires. Se registraron características y comorbilidades al ingreso, al inicio de la asistencia respiratoria mecánica, complicaciones y evolución en el Hospital y a los 6 meses. Los 200 pacientes incluidos fueron divididos en dos grupos: Grupo 1 (n = 164 menores de 80 años y Grupo 2 (n = 36 de 80 años o más. No hubo diferencias en la mortalidad en la Unidad de Cuidados Intensivos y en el Hospital entre los pacientes menores de 80 años y los de 80 años o más. (55.56% vs. 41.46% y 58.33% vs. 42.68%. La supervivencia a los 6 meses de los = 80 años fue significativamente menor (22.22% vs. 48.17%, p = 0.0051. En el análisis multivariado solamente un APACHE II > 20 (p = 0.0007 o la ausencia de vida autónoma (p = 0.0028 conservaron poder predictivo independiente. Los pacientes añosos que reciben asistencia respiratoria mecánica no presentan una mayor mortalidad por el sólo hecho de ser ancianos. La restricción de los cuidados terapéuticos invasivos no parece justificada por la edad avanzada.

Diseño: Estudio tipo encuesta. Institución: Facultad de Medicina, Universidad Nacional Mayor de San Marcos, Lima, Perú. Participantes: Alumnos entre quinto de primaria y quinto de secundaria de colegios privados. Intervenciones: Una encuesta validada en estudios previos, para identificar violencia escolar (bullying, fue aplicada a 736 alumnos, entre quinto de primaria y quinto de secundaria, de colegios privados de Ayacucho, Huancavelica y Cusco (Sicuani. Se consideró bullying severo cuando contestaron positivamente 5 a más de las 9 opciones posibles de la pregunta que indagaba sobre los tipos de violencia. Se comparó 37 alumnos portadores de bullying severo con 74 alumnos tomados al azar del grupo que no tuvo violencia. Con análisis bivariado y multivariado de regresión logística se identificó factores asociados significativamente a la violencia escolar severa. Principales medidas de resultados: Factores de riesgo de violencia escolar (bullying severa. Resultados: La violencia escolar severa se asoció significativamente con reacción de padres al conocer el hecho, repetición de la amenaza a pesar de comunicar las agresiones, presencia de pandilleros en el colegio, tener amigos pandilleros y poseer defecto físico. La regresión logística encontró asociación significativa con la reacción de los padres, presencia de pandilleros y poseer un defecto físico. Conclusiones: Se ha encontrado que la violencia escolar severa se asocia a múltiples factores de riesgo, que pueden y deben ser detectados precozmente, debido al daño psicológico que produce en los estudiantes.

    Full Text Available Las infecciones respiratorias agudas constituyen la primera causa de consultas médicas y de morbilidad, tanto en los países desarrollados como en los países en vías de desarrollo. Los niños menores de 5 años tienen algunas características fisiológicas e inmunológicas que los hacen más susceptibles para presentar estos procesos respiratorios. A pesar que las infecciones respiratorias agudas bajas concentran habitualmente la atención por su mayor complejidad, costo del tratamiento y complicaciones, son las altas las que se presentan en mayor número en la consulta ambulatoria. Por la frecuente presentación en la consulta de alergología y por la carga de ansiedad que se genera en los familiares de estos niños con infecciones respiratorias recurrentes, nos decidimos a realizar una revisión sobre algunos aspectos de interés relacionados con ellas. Nuestro objetivo es mejorar el conocimiento de estas entidades, para identificar aquellos niños con mayor riesgo de presentar recurrencia de estas infecciones respiratorias. Estas entidades, que en su mayoría son de etiología viral y curso limitado, son causa importante de uso y abuso de medicamentos, entre ellos, los antibióticos, con efectos perjudiciales en la salud de los niños.Acute respiratory infections are the first cause of visits to the physician's offices and of morbidity in the developing and developed countries. Children under 5 have some physiological and immunological characteristics that make them more susceptible to present these respiratory processes. In spite of the fact that the lower respiratory infection usually attracts the attention due to their greater complexity, cost of treatment and complications, the upper are more frequent at the outpatient department. Due to their common presentation at the allergology department and to the load of anxiety generated in the relatives of these children with recurrent respiratory infections, it was decided to make a review of

    Full Text Available Introdução: A epistaxe severa, geralmente associada a fatores predisponentes como hipertensão arterial sistêmica e coagulopatia, é uma doença desafiadora, e pode necessitar de uma abordagem cirúrgica nos casos que não respondem ao tratamento conservador, como cauterização e tamponamento nasal. Objetivo: avaliar os resultados da ligadura endoscópica endonasal da artéria esfenopalatina no tratamento da epistaxe severa refratária à abordagem terapêutica conservadora. Forma de estudo: Clínico prospectivo. Material e Método: foram avaliados doze casos de pacientes submetidos à ligadura endoscópica endonasal da artéria esfenopalatina no tratamento da epistaxe severa não responsiva ao tratamento conservador, observando-se a história clínica, os fatores predisponentes, a evolução e as complicações deste procedimento. Resultados: a idade média foi de 50,9 anos, e a distribuição por sexo foi de 33% do sexo feminino e 67% do sexo masculino; 33% apresentaram HAS e 16,6% coagulopatia (hepatopatia como fatores predisponentes. Um paciente (8,3% apresentou ressangramento após o procedimento cirúrgico. Discussão: a ligadura endoscópica endonasal da artéria esfenopalatina representa uma abordagem segura e garante um controle satisfatório do sangramento, com índice de ressangramento de 8,3% entre os nossos casos. Conclusão: a ligadura endoscópica endonasal da artéria esfenopalatina representa uma opção cirúrgica adequada, pois não apresenta as complicações das técnicas anteriores, atinge um controle satisfatório do sangramento e pode ser realizada por otorrinolaringologistas habituados à cirurgia endoscópica nasal.

    Full Text Available OBJETIVO: Mejorar la calidad de la atención hospitalaria de los niños con infecciones respiratorias agudas bajas, aumentar los conocimientos sobre esa patología y mejorar la eficiencia en el uso de los recursos asistenciales, por medio de una estrategia que se denominó Plan de Invierno.MÉTODOS: La estrategia se basó en la utilización de protocolos de diagnóstico y tratamiento, internación por cuidados progresivos y por enfermedad, adecuación de los recursos asistenciales y creación de un sistema de registro permanente, informatizado. Se incorporó la investigación sistemática de la etiología viral para racionalizar el uso de la medicación y reducir las infecciones intrahospitalarias. RESULTADOS: Durante la aplicación del Plan (19/V-19/IX/99 ingresaron 3.317 niños; 1.347 (40.61% presentaban infecciones respiratorias agudas bajas. Se captaron 1.096 (81%, de los cuales 71% eran menores de un año. Predominaron las infecciones respiratorias virales (68%. Los criterios de ingreso fueron saturación de oxígeno <95%, polipnea, tiraje o derrame pleural en el 92.4% de los niños. La magnitud de la demanda impidió que las pautas de aislamiento individual o en grupo se cumplieran en todos los casos. El uso de la medicación se ajustó a lo recomendado en un elevado porcentaje: no recibieron antibióticos 73% de las bronquiolitis ni 72% de las neumonías virales, y 96% de las neumonias bacterianas los recibieron según pauta; se redujo el uso de broncodilatadores y de corticoides. El gasto en medicamentos disminuyó fundamentalmente en el grupo de los corticoides y tuvo el mayor impacto en el costo por día/cama de antibióticos. CONCLUSIONES: Disminuir la morbimortalidad por infecciones respiratorias agudas bajas requiere continuar mejorando la calidad de la atención hospitalaria y fortalecer los programas de promoción de salud y de control de las enfermedades prevalentes, en el primer nivel de atención.

    Full Text Available El objetivo de este trabajo fue el de verificar la eficiencia del tratamiento químico en la prevención del taponamiento de los sistemas de goteo, cuando se usa aguas residuales sanitarias tratadas. Para la realización del ensayo experimental fue construida una plataforma de ensayos con la finalidad de abastecer cuatro unidades de irrigación por goteo con aguas residuales sanitarias, tratada y filtradas mediante un filtro de disco de 120 mesh. Fueron ensayados tres modelos de goteros (M1, M2 y M3 durante un período de 560 horas. En el tratamiento químico fueron ensayadas las concentraciones de cloro residual libre de 0; 0,4; 1,0 y 1,9 mg L-1. A partir de los resultados obtenidos se tienen las siguientes conclusiones: el agua residual sanitaria, tratada por aplicación vía sistema de irrigación por goteo propicio la formación de un biofilme en los goteros, resultante de la interacción entre colonias de bacterias y algas. La aplicación de cloro en el agua residual sanitaria tratada, minimizó el desarrollo del biofilme en el interior de los goteros y de las líneas laterales de irrigación; además, se encontró que los goteros con mayor diámetro en el laberinto y con mas de un filtro secundario (M2 y M3, son mas susceptibles al taponamiento cuando trabajan con aguas residuales tratadas. La concentración de cloro residual libre de 0,4 mg L-1 fue mas sustentable en la prevención de taponamiento por biofilme en sistemas de riego por goteo que operan con agua residual domestica tratada.

    Full Text Available Virtualmente todos los pacientes con esclerosis lateral amiotrófica tendrán disnea, que es quizá el síntoma más penoso de esta devastadora enfermedad. El objetivo de este estudio fue correlacionar la dimensión respiratoria de la escala ALSFRS-R, la capacidad vital forzada y las presiones estáticas máximas bucales. Se estudiaron prospectivamente 20 pacientes consecutivos sin disnea durante 24 meses. El puntaje total de la escala ALSFRS-R disminuyó de 34.3 ± 10.3 a 22.1 ± 8.0 (p = 0.0325; la contribución de la dimensión respiratoria fue insignificante. En quienes refirieron disnea (n: 12, la capacidad vital forzada cayó un 41 ± 21 % del valor inicial pero con similar caída (46 ± 23%, 8 pacientes no refirieron disnea. La correlación entre la escala ALSFRS-R con la capacidad vital forzada (litros fue r: 0.73, (p = 0.0016 y con la presión inspiratoria máxima (cm H2O, r: 0.84, p = 0.0038. La correlación entre la capacidad vital forzada (% con la disnea fue r s: 0.23, p = 0.1400. La correlación de la disnea con la presión inspiratoria máxima (% fue r s: 0.58, p = 0.0300 y con la presión espiratoria máxima (%, r s: 0.49, p = 0.0400. La dimensión respiratoria de la escala ALSFRS-R no permitió predecir el grado de deterioro funcional respiratorio. Esto sugiere que dicha dimensión no reemplaza a las mediciones funcionales respiratorias y, debido a que la insuficiencia respiratoria puede no ser evidente, la realización de dichas pruebas provee una base objetiva de seguimiento y permite planear medidas con anticipación.Virtually all patients with amyotrophic lateral sclerosis will complain of dyspnea, which is perhaps the most distressing symptom of this devastating disease. The objective was to correlate respiratory domain of ALSFRS-R with forced vital capacity and maximal static pressures in the mouth. We designed a prospective study in 20 consecutive patients without dyspnea during 24 months. The global decline of ALSFRS

    Full Text Available Cardio-metabolic disease, namely ischemic heart disease, stroke, obesity, and type 2 diabetes, represent substantial health and economic burdens. Almost one half of cardio-metabolic deaths in the U.S. might be prevented through proper nutrition. Plant-based (vegetarian and vegan diets are an effective strategy for improving nutrient intake. At the same time, they are associated with decreased all-cause mortality and decreased risk of obesity, type 2 diabetes, and coronary heart disease. Evidence suggests that plant-based diets may reduce the risk of coronary heart disease events by an estimated 40% and the risk of cerebral vascular disease events by 29%. These diets also reduce the risk of developing metabolic syndrome and type 2 diabetes by about one half. Properly planned vegetarian diets are healthful, effective for weight and glycemic control, and provide metabolic and cardiovascular benefits, including reversing atherosclerosis and decreasing blood lipids and blood pressure. The use of plant-based diets as a means of prevention and treatment of cardio-metabolic disease should be promoted through dietary guidelines and recommendations.

    As part of the peer review process for the European Journal of Cardio-Thoracic Surgery (EJCTS) and the Interactive CardioVascular and Thoracic Surgery (ICVTS), a statistician reviews any manuscript that includes a statistical analysis. To facilitate authors considering submitting a manuscript and to make it clearer about the expectations of the statistical reviewers, we present up-to-date guidelines for authors on statistical and data reporting specifically in these journals. The number of statistical methods used in the cardiothoracic literature is vast, as are the ways in which data are presented. Therefore, we narrow the scope of these guidelines to cover the most common applications submitted to the EJCTS and ICVTS, focusing in particular on those that the statistical reviewers most frequently comment on. © The Author 2015.

    Full Text Available Objetivo. Establecer la incidencia de infección respiratoria y los patrones de colonización faríngea en niños que asisten a guarderías. Material y métodos. Se realizó un estudio de cohorte en niños menores de cuatro años de edad, de uno u otro sexo, asistentes a la guardería del Hospital Infantil de México Federico Gómez, de la Ciudad de México, durante abril a octubre de 1999. Se registró la presencia de infección de vías aéreas superiores cada semana, y de colonización cada tres meses, mediante un exudado nasofaríngeo. Se hizo estadística descriptiva de las variables analizadas. Se determinaron tasas de infección respiratoria aguda. Resultados. Se estudiaron 85 niños, 40 del sexo femenino (47% y 45 del sexo masculino (53% durante un total de 9 090 niños/día de seguimiento. Tres niños tenían antecedentes de atopia (3.52%, seis niños antecedentes de asma (7.05%, y 39 eran expuestos a tabaquismo pasivo (45.88%. Se diagnosticaron 246 rinofaringitis (95.3%, nueve otitis media aguda (3.48%, tres bronquiolitis (1.16%, para un total de 258 eventos de infección respiratoria aguda. La tasa de incidencia global fue de 10.35 infecciones por niño/año de observación (IC 95% 8.7-12.0. La incidencia de otitis y bronquiolitis fue de 0.36 y 0.12 eventos por niño/año de observación. Se tomaron cultivos nasofaríngeos con una prevalencia de colonización para S. pneumoniae de 20.4%, H. influenzae no tipificable 13.1% y Moraxella catarrhalis 8.1%. Conclusiones. Los resultados no sólo demuestran una alta prevalencia de colonización debido a cepas invasivas, sino que también revelan una tasa de incidencia de infección respiratoria aguda del doble de lo reportado en estudios de comunidad. Estos resultados ayudan a caracterizar un problema pobremente documentado en nuestro país.

    Full Text Available Background: Cardio-respiratory capacity is an important factor in human health. It's quality depends on many objective factors (such as age and gender, but it can be influenced also by others (physical activity, nutrition. Low level of cardio-respiratory capacity significantly correlates with numerous health failures. Objective: Evaluation of the cardio-respiratory capacity in athletes enables a prediction of performance. In a non-sporting population a critically low level of cardio-respiratory capacity could be a warning signal of a high risk of diseases. The Spiroergometric examination needs very sophisticated technical equipment including O2-CO2 analyzer. The aim of the study was to examine the possibility of how to replace direct measurement of oxygen consumption by the method. Methods: 2 777 protocols from the data base of examinations performed in the period of 1994 till 2015 were used. Cardio-respiratory capacity in all examinations was evaluated according to maximal oxygen uptake VO2max, physical working capacity W170 and maximal performance on the cyclo-ergometer. Step-vice increased workload on cyclo-ergometer based on procedure used in International Biological Program was applied to obtain the characteristics of cardio-respiratory capacity of each subject (2 015 men and 762 women. Results: Correlation coefficients r and regression equations of cardio-respiratory capacity characteristics (W170, W170/kg, VO2max, VO2max/kg, Wmax, Wmax/kg were calculated. The highest correlation was found between VO2max and Wmax and between VO2max/kg and Wmax/kg, both in men and women (r = .89 in men and r = .85 in women for VO2max and Wmax. The most important regression equations are: (men VO2max = 0.0095 . Wmax + 0.54 (l/min (r = .89, VO2max/kg = 8.3 . Wmax/kg + 13 (ml/min/kg (r = .83; (women VO2max = 0.0083 .

    Cardio-oncology is a relatively new discipline that focuses on the cardiovascular sequelae of anti-tumour drugs. As any other young adolescent discipline, cardio-oncology struggles to define its scientific boundaries and to identify best standards of care for cancer patients or survivors at risk of cardiovascular events. The International Colloquium on Cardio-Oncology was held in Rome, Italy, 12–14 March 2014, with the aim of illuminating controversial issues and unmet needs in modern cardio-oncology. This colloquium embraced contributions from different kind of disciplines (oncology and cardiology but also paediatrics, geriatrics, genetics, and translational research); in fact, cardio-oncology goes way beyond the merging of cardiology with oncology. Moreover, the colloquium programme did not review cardiovascular toxicity from one drug or the other, rather it looked at patients as we see them in their fight against cancer and eventually returning to everyday life. This represents the melting pot in which anti-cancer therapies, genetic backgrounds, and risk factors conspire in producing cardiovascular sequelae, and this calls for screening programmes and well-designed platforms of collaboration between one key professional figure and another. The International Colloquium on Cardio-Oncology was promoted by the Menarini International Foundation and co-chaired by Giorgio Minotti (Rome), Joseph R Carver (Philadelphia, Pennsylvania, United States), and Steven E Lipshultz (Detroit, Michigan, United States). The programme was split into five sessions of broad investigational and clinical relevance (what is cardiotoxicity?, cardiotoxicity in children, adolescents, and young adults, cardiotoxicity in adults, cardiotoxicity in special populations, and the future of cardio-oncology). Here, the colloquium chairs and all the session chairs briefly summarised what was said at the colloquium. Topics and controversies were reported on behalf of all members of the working group

    In healthy subjects self-regulation of the organism establishes the order of rhythmical functions. This self-regulation is altered in patients suffering from idiopathic orthostatic syndrome resulting from disturbances of functional aspects only. Thus the cardio-respiratory coordination, which may serve as the representative of the order of rhythmical functions, is modified. In the case of idiopathic orthostatic syndrome the anthroposophic medicine offers the medicament Cardiodoron(r). Does it stimulate self-regulation in order to normalise the cardio-respiratory coordination? This claim is analysed by a systematic review of the literature. Only those publications were considered where the cardio-respiratory coordination was analysed in studies with patients or healthy subjects. The methods of the studies with patients and healthy subjects vary strongly. Nevertheless, a normalisation of the cardio-respiratory coordination could be found in studies with patients suffering from idiopathic orthostatic syndrome as well as in studies with healthy subjects. The studies show that the use of the medicament results in a normalisation of the cardiorespiratory coordination. By stimulating the self-regulation the medicament leads to an improvement of the order of rhythmical functions in the human organism. Copyright 2002 S. Karger GmbH, Freiburg

    Full Text Available White adipose tissue (WAT asset, in terms of cell number, fat storage capacity and endocrine function, is largely determined in early stages of life and is pivotal for shaping the WAT pro-inflammatory behavior. WAT derived adipokines have been shown to play a main role in several cardio-metabolic abnormalities of obesity. This review focuses on the most recently identified adipokines, namely adipocyte-fatty acid-binding protein, chemerin, fibroblast growth factor-21, lipocalin-2, omentin-1 and vaspin; their role in the pathogenesis of obesity and associated cardio-metabolic abnormalities; and on their adaptive response to body weight change. Evidence consistently suggests a pathogenic role for A-FABP, chemerin and FGF-21. Nevertheless, large population studies are needed to verify whether they can be useful to predict the risk of cardio-metabolic abnormalities in adulthood and/or monitor the clinical response to therapeutic interventions.

    Full Text Available This study examines the association of long-term exposure to gaseous air pollution with cardio-respiratory mortality in Brisbane, Australia, in the period 1996-2004. The pollutant concentrations were estimated using geographical information system (GIS techniques at the statistical local area (SLA level. The generalized estimating equations model was used to investigate the impact of nitrogen dioxide (NO2, ozone (O3 and sulphur dioxide (SO2 on mortality due to cardio-respiratory disease after adjusting for a range of potential confounders. An increase of 4.7% (95% confidence interval = 0.7-8.9% in cardio-respiratory mortality for 1 part per billion (ppb increment in annual average concentration of SO2 was estimated. However, there was no significant association between long-term exposures to NO2 or O3 and death due to cardio-respiratory disease. The results indicate that the annual average concentration of SO2 is associated with cardio-respiratory mortality at the SLA level and this association appears to vary with the geographical area.

    More than 130 FDA-approved drugs have been identified for now to prolong the QT interval and possibly lead to sudden cardiac death. Due to their toxic effect, some of these drugs have been withdrawn from the pharmaceutical market. In this study, we have formulated few rules to assess the ability to prolong QT interval and thereby discriminate between cardiotoxic and -safe drugs. These rules have clearly determined that cardio-toxic drugs are more likely to obey Lipinski rule of 5 and Oprea lead-like rule. Moreover, the cardio-toxic drugs have been found to have in common values of -0.5 to 6.5 log P, 1-5 nitrogen atoms, up to 4 oxygen atoms, 5-27 hydrophobic atoms, and 15-53 single bonds. Matthews Correlation Coefficient with the value of 0.6 was also attained and nearly 96% of the cardio-toxic drugs were successfully covered. Thus, despite the simplicity of this methodology, we have obtained interesting and informative results. The proposed set of these simple rules could be employed to infer cardio-toxicity or -safety for current and potential drugs. The present study will have important impact on decision making in the fields of drug development, molecule screening in biological assays, and other applications as well. PMID:19759813

    2016-02-01

    Full Text Available Introduction: The main cardio-metabolic diseases – mostly cardiovascular diseases such as stroke and ischemic heart disease – share common clinical markers such as raised blood pressure and blood glucose. The pathways of development of many of these conditions are also interlinked. In this regard, a higher level of co-occurrence of the main cardio-metabolic disease markers is expected. Evidence about the patterns of occurrence of cardio-metabolic markers and their interlinkage in the sub-Saharan African setting is inadequate. Objective: The goal of the study was to describe the interlinkage among common cardio-metabolic disease markers in an African setting. Design: We used data collected in a cross-sectional study from 5,190 study participants as part of cardiovascular disease risk assessment in the urban slums of Nairobi, Kenya. Five commonly used clinical markers of cardio-metabolic conditions were considered in this analysis. These markers were waist circumference, blood pressure, random blood glucose, total blood cholesterol, and triglyceride levels. Patterns of these markers were described using means, standard deviations, and proportions. The associations between the markers were determined using odds ratios. Results: The weighted prevalence of central obesity, hypertension, hyperglycemia, hypercholesterolemia, and hypertriglyceridemia were 12.3%, 7.0%, 2.5%, 10.3%, and 17.3%, respectively. Women had a higher prevalence of central obesity and hypercholesterolemia as compared to men. Blood glucose was strongly associated with central obesity, blood pressure, and triglyceride levels, whereas the association between blood glucose and total blood cholesterol was not statistically significant. Conclusions: This study shows that most of the common cardio-metabolic markers are interlinked, suggesting a higher probability of comorbidity due to cardio-metabolic conditions and thus the need for integrated approaches.

Estas partículas pueden penetrar en el sistema respiratorio bloqueando el paso del aire y ocasionando enfermedades. La contaminación por material particulado en la ciudad de Santa Marta requiere ser estudiada para comprender el daño que produce sobre la salud de la población, en concreto en la población infantil y adulta mayor. El transporte y almacenamiento de carbón, además del clima, son los causantes del esparcimiento de partículas PM10, que afectan principalmente las vías respiratorias altas. Para conocer lo que está pasando con la salud respiratoria se realizó un estudio descriptivo que incluyó como población a todos los niños entre 6 y 14 años de base hospitalaria. La información se depuró dejando únicamente los diagnósticos de vías respiratorias superiores.

    Full Text Available Diferentes investigadores han realizado estudios sobre el manejo del niño febril y plantean que es un dilema al que se enfrenta a diario el médico que atiende niños. Motivados por este tema se efectuó un estudio descriptivo retrospectivo de los niños febriles, sin causa aparente en su valoración inicial, que asistieron al servicio de urgencias en un período de 9 meses, con el objetivo de identificar el diagnóstico definitivo al egreso y se precisó el tipo de infección bacteriana severa y relacionó la presencia de éstos con parámetros clínicos y de laboratorios. El mayor número de niños febriles valorados e ingresados mostraron edades desde 91 días hasta 36 meses. El menor porcenaje de ellos ingresaron y desarrollaron alguna infección bacteriana severa principalmente neumonía, y fue mayor el porcentaje de niños con esta patología a menos edad con predominio del aspecto tóxico y de la temperatura 39 EC. Resultó el manejo ambulatorio del niño febril mayor de 90 días y bajo riesgo de infección bacteriana severa un ahorro en vidas y dinero, por lo que se recomienda generalizar el flujograma propuesto para la evaluación y manejo del niño febril de 3 a 36 meses de edad.Different researches have performed studies on the management of the febrile infant and they point out that this is a dilemma faced by every physician who takes care of children.

    Rodent and nonhuman primate (NHP) studies indicate that developmental programming by reduced perinatal nutrition negatively impacts life course cardio-metabolic health. We have developed a baboon model in which we feed control mothers (CON) ad libitum while nutrient restricted mothers are fed 70% of ad libitum global feed in pregnancy and lactation. Offspring of nutrient restricted mothers are intrauterine growth restricted (IUGR) at term. By 3.5 years IUGR baboons showed signs of insulin resistance, indicating a pre-diabetic phenotype, in contrast to healthy CON offspring. We hypothesized that a novel breath analysis approach would provide markers of the altered cardio-metabolic state in a non-invasive manner. Here we assess whether exhaled breath volatile organic compounds (VOCs) collected from this unique cohort of juvenile baboons with documented cardio-metabolic dysfunction resulting from in utero programming can be detected from their breath signatures. Breath was collected from male and female CON and IUGR baboons at 4.8±0.2 years (human equivalent ~13 years). Breath VOCs were quantified using a two-dimensional gas chromatography mass spectrometer (2D GC-MS). Two-way ANOVA, on 76 biologically relevant VOCs identified 27 VOCs (p<0.05) with altered abundances between groups (sex, birthweight, and sex x birthweight). The 27 VOCs included 2-pentanone, 2-octanone, 2,5,5 trimethyl-1-hexene and 2,2-dimethyl-undecane, which have not previously been associated with cardio-metabolic disease. Unsupervised principal component analysis of these VOCs could discriminate the four defined clusters defining males, females, CON and IUGR. This study, which is the first to assess quantifiable breath signatures associated with cardio-metabolic programing for any model of IUGR, demonstrates the translational value of this unique model to identify metabolites of programmed cardio-metabolic dysfunction in breath signatures. Future studies are required to validate the

    Turner syndrome (TS) is a genetic disorder characterized by the (partial) absence or a structural aberration of the second sex chromosome and is associated with a variety of phenotypes with specific physical features and cardio-aortic malformations. The objective of this study was to gain a better insight into the differences in dysmorphic features between girls and women with TS and to explore the association between these features, karyotype and cardio-aortic malformations. This prospective study investigated 14 dysmorphic features of TS girls and women using a checklist. Three major phenotypic patterns were recognized (severe phenotype, lymphatic phenotype and skeletal phenotype). Patient data including karyotype and cardio-aortic malformations (bicuspid aortic valve (BAV) and aortic coarctation (COA)) were collected. Associations between the prevalence of dysmorphic features, karyotype and cardio-aortic malformations were analysed using chi 2 -test and odds ratios. A total of 202 patients (84 girls and 118 women) were analysed prospectively. Differences in prevalence of dysmorphic features were found between girls and women. A strong association was found between monosomy 45,X and the phenotypic patterns. Furthermore, an association was found between COA and lymphatic phenotype, but no association was found between karyotype and cardio-aortic malformations. This study uncovered a difference in dysmorphic features between girls and women. Monosomy 45,X is associated with a more severe phenotype, lymphatic phenotype and skeletal phenotype. All patients with TS should be screened for cardio-aortic malformations, because in contrast to previous reports, karyotype and cardio-aortic malformations showed no significant association.

    Cardio-Oncology is the care of cancer patients with cardiovascular disease, overt or occult, already established or acquired during treatment. Cancer patients can present with a variety of cardiovascular problems not all of which are directly related to cancer therapy (medications or radiotherapy). The cardiovascular problems of oncology patients can range from ischaemia to arrhythmias and can also include valve problems and heart failure. As such, within cardiology, teamwork is required with members of different cardiology subspecialties. The way forward will be to adopt a multidisciplinary approach to produce optimal individual care. Close collaboration between cardiology and oncology specialists in a Cardio-Oncology setting can make this happen. Copyright © 2017. Published by Elsevier B.V.

    The aim of the study was to assess the associations of individual and combined physical fitness components with single and clustering of cardio-metabolic risk factors in children. This 2-year longitudinal study included a total of 1635 European children aged 6-11 years. The test battery included cardio-respiratory fitness (20-m shuttle run test), upper-limb strength (handgrip test), lower-limb strength (standing long jump test), balance (flamingo test), flexibility (back-saver sit-and-reach) and speed (40-m sprint test). Metabolic risk was assessed through z-score standardization using four components: waist circumference, blood pressure (systolic and diastolic), blood lipids (triglycerides and high-density lipoprotein) and insulin resistance (homeostasis model assessment). Mixed model regression analyses were adjusted for sex, age, parental education, sugar and fat intake, and body mass index. Physical fitness was inversely associated with clustered metabolic risk (P<0.001). All coefficients showed a higher clustered metabolic risk with lower physical fitness, except for upper-limb strength (β=0.057; P=0.002) where the opposite association was found. Cardio-respiratory fitness (β=-0.124; P<0.001) and lower-limb strength (β=-0.076; P=0.002) were the most important longitudinal determinants. The effects of cardio-respiratory fitness were even independent of the amount of vigorous-to-moderate activity (β=-0.059; P=0.029). Among all the metabolic risk components, blood pressure seemed not well predicted by physical fitness, while waist circumference, blood lipids and insulin resistance all seemed significantly predicted by physical fitness. Poor physical fitness in children is associated with the development of cardio-metabolic risk factors. Based on our results, this risk might be modified by improving mainly cardio-respiratory fitness and lower-limb muscular strength.

    Full Text Available Objective: To compare patients with panic disorder with agoraphobia treated with cognitive-behavioural therapy (CBT associated with the medication with patients treated only with medication and verify the behaviour of the cardio-respiratory symptoms of both groups. Methods: Randomized sample in the Psychiatry Institute of the Federal University of Rio de Janeiro, divided in two groups of 25 participants each. Group 1 undertook 10 weekly sessions of CBT with one hour of duration each together with medication. Group 2, Control, were administered medication that only consisted of tricyclic anti-depressants and selective inhibitors of the re-uptake of serotonin. Evaluation instruments were applied at the beginning and to the end of the interventions. Results: According to the applied scales, group 1 showed statistically more significant results than group 2, with: reduction of panic attacks, cardio-respiratory symptoms, anticipatory anxiety, agoraphobia avoidance and fear of bodily sensations. Conclusion: Exposures (in vivo and interoceptive, especially for induction symptom exercises and relaxation, were considered essential to prepare patients with panic disorder to handle future cardio-respiratory symptoms and panic attacks with agoraphobia.

    Improved cancer survivorship has resulted in a growing number of Canadians affected by cancer and cardiovascular disease. As a consequence, cardio-oncology programs are rapidly emerging to treat cancer patients with de novo and preexisting cardiovascular disease. The primary goal of a cardio-oncology program is to preserve cardiovascular health to allow the timely delivery of cancer therapy and achieve disease-free remission. Multidisciplinary programs in oncology and cardiology have been associated with enhanced patient well-being and improved clinical outcomes. Because of the complex needs of these multisystem patients, a similar model of care is gaining acceptance. The optimal composition of the cardio-oncology team will typically involve support from cardiology, oncology, and nursing. Depending on the clinical scenario, additional consultation from dietetics, pharmacy, and social services might be required. Timely access to consultation and testing is another prerequisite for cardio-oncology programs because delays in treating cardiac complications and nonadherence to prescribed cancer therapy are each associated with poor outcomes. Recommended reasons for referral to cardio-oncology programs include primary prevention for those at high risk for cardiotoxicity and the secondary treatment of new or worsening cardiovascular disease in cancer patients and survivors. Management is multifaceted and can involve lifestyle education, pharmacotherapy, enhanced cardiovascular surveillance, and support services, such as exercise training. The lack of evidence to guide clinical decisions and recommendations in cardio-oncology is a major challenge and opportunity for health care professionals. Large multicentre prospective registries are needed to adequately power risk model calculations and generate hypotheses for novel interventions. Copyright © 2016 Canadian Cardiovascular Society.

Se tomaron tres muestras: reposo, inmediatamente después del ejercicio y a las 6 horas posejercicio. Para la frecuencia cardiaca se utilizó un monitor POLAR S625; la frecuencia respiratoria se determinó mediante fonendoscopio; y las enzimas y el ácido láctico se analizaron en laboratorio. Se utilizó el método estadístico ANAVA para enzimas musculares y acido láctico y estadística descriptiva para frecuencia cardiaca y respiratoria. En los resultados se encontró un comportamiento estadísticamente significativo (p < 0.05 del ácido láctico y la enzima creatinkinasa, a diferencia del comportamiento de la enzima lactato deshidrogenasa, que fue no significativo. Las frecuencias cardiaca y respiratoria se elevaron de manera significativa posejercicio y regresaron a lo normal alrededor de las 6 seis horas. El ácido láctico se incrementó posejercicio y disminuyó a las 6 horas, contrario a lo reportado por otros autores. Se concluye que una vez analizadas estas variables, hay diferencias con los valores obtenidos por otros autores, que pueden deberse a la altitud, al tipo y tiempo de ejercicio realizado.

    Patient motion during medical imaging using techniques such as computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), or single emission computed tomography (SPECT) is well known to degrade images, leading to blurring effects or severe artifacts. Motion correction methods try to overcome these degrading effects. However, they need to be validated under realistic conditions. In this work, a sophisticated anthropomorphic thorax phantom is presented that combines several aspects of a simulator for cardio-respiratory motion. The phantom allows us to simulate various types of cardio-respiratory motions inside a human-like thorax, including features such as inflatable lungs, beating left ventricular myocardium, respiration-induced motion of the left ventricle, moving lung lesions, and moving coronary artery plaques. The phantom is constructed to be MR-compatible. This means that we can not only perform studies in PET, SPECT and CT, but also inside an MRI system. The technical features of the anthropomorphic thorax phantom Wilhelm are presented with regard to simulating motion effects in hybrid emission tomography and radiotherapy. This is supplemented by a study on the detectability of small coronary plaque lesions in PET/CT under the influence of cardio-respiratory motion, and a study on the accuracy of left ventricular blood volumes.

    CardioCard is a CDROM of credit card size containing medical information on cardiac patients. Patient data acquired during hospital stay are stored in PDF format and secured by a password known to patients only. In a consecutive series of patients, we assessed acceptance and utility of this new information medium. A questionnaire was sent to all patients who had received CardioCard over a one-year period. The questionnaire was returned by 392 patients (73%). 44% of patients had the card with them all the time. The majority of patients (73%) considered the CardioCard useful (8% not useful, 19% no statement) and most (78%) would even agree to bear additional costs. Only 5% worried about data security. In contrast, 44% would be concerned of data transmission via internet. During an observation period of 6 (SD 3) months, data were accessed by 27% of patients and 12% of their physicians. The proportion of card users was lower among older patients: 70 y, 16% and particularly among older women: 61.70 y, 9%; >70 y, 5%. Technical problems during data access occurred in 34%, mostly due to incorrect handling. A majority of patients considered CardioCard as useful and safe. Lack of hardware equipment or insufficient computer knowledge, but not safety issues were the most important limitations. As patients expressed concerns regarding protection of privacy if data were accessible via internet, this would remain a strong limiting factor for online use.

    Full Text Available A growing number of evidences report that aging represents the major risk factor for the development of cardio and cerebrovascular diseases. Understanding Aging from a genetic, biochemical and physiological point of view could be helpful to design a better medical approach and to elaborate the best therapeutic strategy to adopt, without neglecting all the risk factors associated with advanced age. Of course, the better way should always be understanding risk-to-benefit ratio, maintenance of independence and reduction of symptoms. Although improvements in treatment of cardiovascular diseases in the elderly population have increased the survival rate, several studies are needed to understand the best management option to improve therapeutic outcomes. The aim of this review is to give a 360° panorama on what goes on in the fragile ecosystem of elderly, why it happens and what we can do, right now, with the tools at our disposal to slow down aging, until new discoveries on aging, cardio and cerebrovascular diseases are at hand.

    The role of uric acid as a risk factor for cardio-cerebrovascular diseases is controversial. In this study, we aimed to investigate the relationship between serum uric acid level and the risk of cardio-cerebrovascular events in middle-aged and non-obese Chinese men. We included 3152 participants from the health examination center of Tongji Hospital from June 2007 to June 2010. Clinical examination and medical records were collected at the annual health examination. The hazard ratios (HRs) of uric acid for cardio-cerebrovascular events were calculated by Cox proportional hazards models. Generalized additive model and threshold effect analysis were used to explore the non-linear relationship between serum uric acid level and the incidence of cardio-cerebrovascular event. The mean follow-up time was 52 months. When the participants were classified into four groups by the serum acid quarter (Q1-Q4), the HRs (95% CI) of Q2-Q4 for cardio-cerebrovascular events were 1.26 (0.83, 1.92), 1.97 (1.33, 2.91) and 2.05 (1.40, 3.01), respectively, compared with the reference (Q1). The actual incidence and conditional incidence of cardio-cerebrovascular events in the high serum acid group were higher than those in the low serum acid group, which were stratified by the turning point (sUA = 372 μmol/L). We also showed a strong prognostic accuracy of the multiple variable-based score in 3 years and 5 years, with area under the receiver operating characteristic (ROC) curve of 0.790 (0.756-0.823) and 0.777 (0.749-0.804), respectively. Serum uric acid level is a strong risk factor for cardio-cerebrovascular events.

    To explore the factors influencing cardio-cerebro vascular death events among people over 40 years of age in Shandong area, China. Baseline survey was carried out in 1991. A total number of 11,008 adults over 40 years old had been studied in Shandong province. Data on cardiocerebro death was collected. The correlation between influencing factors and cardio-cerebro vascular death events was analyzed by Cox regression model. Totally, 434 cardio-cerebro death events occurred among the 11,008 subjects during the 8-year follow-up study. Cardio-cerebro death events were related to systolic blood pressure, diastolic blood pressure, smoking, stroke history and age. Data from Cox regression analysis showed that the relative risk (RR) for cardio-cerebro vascular death events increased by 2.862 [95% confidence interval (CI): 1.976-4.144] times for those people having stroke history. When systolic blood pressure, diastolic blood pressure increased by every 10 mm Hg, the relative risk for cardio-cerebro vascular death events increased by 1.171 (95% CI: 1.033-1.328), 1.214 (95% CI: 1.044-1.413) respectively. it was found that a 1.239 (95% CI: 1.088-1.553) times higher in smokers than non-smokers on relative risk for cardio-cerebro vascular death events. However, the predictive values of the influencing factors for cardio-cerebro vascular death were different among population of different years of age. The relative risk for cardio-cerebro vascular death events increased by 1.366 (95% CI: 1.102-1.678) times for each 10 mm Hg increase of diastolic blood pressure in 40-59 years old population. However, the effect was taken place by systolic blood pressure in 60-74 years old population,with a relative risk of 1.201 (95% CI: 1.017-1.418) for each 10 mm Hg increase. Age seemed the only significant factor for cardio-cerebro vascular death events on population aged more than 75 years old. Conclusion The predictive values of the risk factors were different among age groups. The different

This study aimed to assess several dietary patterns, involvement in physical activity and body mass index (BMI of Romanian adults hospitalized because of diagnoses of cardio-vascular diseases (CVD. The study was performed in 2014 in 1 hospital setting from Cluj-Napoca, Romania. It involved 80 adult patients (45 to 78 years old hospitalized with diagnoses of CVD. Anonymous questionnaire assessing several lifestyle related behaviours were filled in by the participants; based on their weight and height, the BMI was calculated. The results show that 76.2% of the participants recognize the role of consumption of fruits and vegetables for cardio-vascular diseases prevention and control, but only 5% meet the recommendations of eating at least 5 portions of fruits and vegetables (around 400 g daily. The majority of the subjects know that the consumption of animal fat increases the risk for cardio-vascular diseases, but, only one out of two patients declared their constant preoccupation for avoiding products rich in saturated fatty acids, such as animal fat, high fat dairy products and high fat meat. Around 80% of the participants know the risk of obesity for cardio-vascular diseases, but 81.2% have a BMI higher than 25. A percentage of 60% of the patients declared that they received general information from health care professionals about diet, physical activity and cardio-vascular disease prevention, while one quarter followed an educational program for this issue and only one out of ten patients followed a personalized program for loosing weight. Comprehensive educational and counselling programs for promoting healthy nutrition and achievement of an appropriate body weight are needed for Romanian adults having CVD

    RESUMEN 

    Este trabajo fue realizado entre los años 2006 y 2008 y tuvo como objetivo determinar la caracterización de la condición funcional respiratoria en los trabajadores de las minas de carbón del municipio de Paipa (Boyacá. Asimismo, con el fin de proponer medidas preventivas de salud ocupacional, se buscó establecer los factores posiblemente asociados a la disfunción respiratoria. En desarrollo de la metodología planteada, se evaluaron los antecedentes  de salud y los aspectos laborales generales de 410 trabajadores a quienes se les aplicó una encuesta. A su vez, por espirometría y oximetría de pulso, se examinaron los parámetros de su función respiratoria. La elevada sintomatología detectada (tos, expectoración, disnea y dolor torácico, sugiere la presencia de enfermedad pulmonar crónica en progreso. Las altas prevalencias de hipoxemia y de anormalidad del patrón respiratorio, relacionadas con una exposición a la mina igual o superior a tres años, indican que dicha enfermedad tiene un origen laboral. Los hallazgos obtenidos permiten afirmar que esta es una ocupación de alto riesgo para la población estudiada.

    Full Text Available Objetivo: Detectar por serología la presencia de micosis de localización pulmonar (Paracoccidioides brasiliensis, Aspergillus sp. e Histoplasma capsulatum, en pacientes con síntomas de enfermedad respiratoria crónica. Diseño: Estudio transversal. Lugar: Alto Huallaga (selva de los departamentos de Huánuco y San Martín, Perú. Pacientes: Se incluyó personas procedentes de seis distritos (Rupa Rupa, Tocache, Uchiza, Santa Lucia, Aucayacu y Puerto Inca - Sungaro con diagnóstico de enfermedad respiratoria crónica baja, tres episodios o más de bronquitis al año y/o tos con expectoración por más de tres meses y en quienes se descartó tuberculosis pulmonar mediante baciloscopia directa. Intervenciones: Por cada persona se llenó una ficha clínica-epidemiológica durante abril a septiembre de 2004, seguido de la toma de una muestra de suero (10 mL para las pruebas de inmunodifusión para Histoplasma capsulatum, Paraccocidiodes brasiliensis, Aspergilus sp, y Aspergillus fumigatus. Principales medidas de resultados: Seroprevalencia de micosis a Histoplasma capsulatum, Aspergilosis spp. y Paracoccidioides brasiliensis. Resultados: De 640 casos, 327 (51,1% fueron de sexo masculino, edad promedio 37,1 años y tiempo de enfermedad de 7,4 meses. La seroprevalencia de micosis fue 1,7% (11/640: 4 Histoplasma capsulatum y 7 Aspergilosis spp. No se obtuvo casos positivos de Paracoccidioides brasiliensis y, en los casos positivos, solo se encontró asociación con 'baja de peso' (p = 0,004. Conclusión: Si bien la frecuencia micoserológica obtenida fue baja, se sugiere en esta zona endémica considerar a las micosis dentro del diagnóstico diferencial de casos con enfermedades respiratorias crónicas bajas, así como la utilización de técnicas de inmunodifusión para el diagnóstico de estas etiologías.

    The traditional Italian dish pasta is a major food source of starch with low glycemic index (GI) and an important low-GI component of the Mediterranean diet. This systematic review aimed at assessing comprehensively and in-depth the potential benefit of pasta on cardio-metabolic disease risk factors. Following a standard protocol, we conducted a systematic literature search of PubMed, CINAHL, and Cochrane Central Register of Controlled Trials for prospective cohort studies and randomized controlled dietary intervention trials that examined pasta and pasta-related fiber and grain intake in relation to cardio-metabolic risk factors of interest. Studies comparing postprandial glucose response to pasta with that to bread or potato were quantitatively summarized using meta-analysis of standardized mean difference. Evidence from studies with pasta as part of low-GI dietary intervention and studies investigating different types of pasta were qualitatively summarized. Pasta meals have significantly lower postprandial glucose response than bread or potato meals, but evidence was lacking in terms of how the intake of pasta can influence cardio-metabolic disease risk. More long-term randomized controlled trials are needed where investigators directly contrast the cardio-metabolic effects of pasta and bread or potato. Long-term prospective cohort studies with required data available should also be analyzed regarding the effect of pasta intake on disease endpoints.

    Cardiovascular diseases are the most popular cause of death in the world recently. For postoperatives, cardiac rehabilitation is still asked to maintain at home (phase II) to improve cardiac function. However, only one third of outpatients do the exercise regularly, reflecting the difficulty for home-based healthcare: lacking of monitoring and motivation. Hence, a cardio-pulmonary rehabilitation system was proposed in this research to improve rehabilitation efficiency for better prognosis. The proposed system was built on mobile phone and receiving electrocardiograph (ECG) signal from a wireless ECG holter via Bluetooth connection. Apart from heart rate (HR) monitor, an ECG derived respiration (EDR) technique is also included to provide respiration rate (RR). Both HR and RR are the most important vital signs during exercise but only used one physiological signal recorder in this system. In clinical test, there were 15 subjects affording Bruce Task (treadmill) to simulate rehabilitation procedure. Correlation between this system and commercial product (Custo-Med) was up to 98% in HR and 81% in RR. Considering the prevention of sudden heart attack, an arrhythmia detection expert system and healthcare server at the backend were also integrated to this system for comprehensive cardio-pulmonary monitoring whenever and wherever doing the exercise.

    Low levels of serum 25-hydroxy vitamin D (25(OH)D), have been associated with development of type 2 diabetes and cardiovascular disease (CVD); however there are limited data on serum 25(OH)D in Indigenous Australians, a population at high risk for both diabetes and CVD. We aimed to assess levels of serum 25(OH)D in Aboriginal and Torres Strait Islander Australians and to explore relationships between 25(OH)D and cardio-metabolic risk factors and diabetes. 592 Aboriginal and/or Torres Strait Islander Australian participants of The eGFR (estimated glomerular filtration rate) Study, a cross-sectional analysis of a cohort study performed in 2007-2011, from urban and remote centres within communities, primary care and tertiary hospitals across Northern Territory, Far North Queensland and Western Australia. Assessment of serum 25(OH)D, cardio-metabolic risk factors (central obesity, diabetes, hypertension, history of cardiovascular disease, current smoker, low HDL-cholesterol), and diabetes (by history or HbA1c ≥6.5%) was performed. Associations were explored between 25(OH)D and outcome measures of diabetes and number of cardio-metabolic risk factors. The median (IQR) serum 25(OH)D was 60 (45-77) nmol/L, 31% had 25(OH)D 72 nmol/L, respectively) after adjusting for known cardio-metabolic risk factors. The percentage of 25(OH)D levels Aboriginal and Torres Strait Islander Australians from Northern and Central Australia. Low 25(OH)D level was associated with adverse cardio-metabolic risk profile and was independently associated with diabetes. These findings require exploration in longitudinal studies.

    Cardio-facio-cutaneous syndrome (CFC) is an uncommon autosomal recessive condition recently distinguished from Noonan syndrome but with more marked growth failure and ectodermal dysplasia. Abdominal symptoms are frequently described but anatomic lesions in CFC have rarely been described. We have found significant anatomic abnormalities in CFC patients including antral foveolar hyperplasia, severe constipation with fecal impaction, nephrocalcinosis and renal cysts. (orig.)

      Objectives Elevated risk factors for a number of chronic diseases have been identified in lorry drivers. Unhealthy lifestyle behaviours such as a lack of physical activity (PA) and high levels of sedentary behaviour (sitting) likely contribute to this elevated risk. This study behaviourally phenotyped UK lorry drivers’ sedentary and non-sedentary behaviours during workdays and non-workdays and examined markers of drivers cardio-metabolic health. Setting A transport company from the East Midlands, UK. Participants A sample of 159 male heavy goods vehicle drivers (91% white European; (median (range)) age: 50 (24, 67) years) completed the health assessments. 87 (age: 50.0 (25.0, 65.0); body mass index (BMI): 27.7 (19.6, 43.4) kg/m2) provided objective information on sedentary and non-sedentary time. Outcomes Participants self-reported their sociodemographic information. Primary outcomes: sedentary behaviour and PA, assessed over 7 days using an activPAL3 inclinometer. Cardio-metabolic markers included: blood pressure (BP), heart rate, waist circumference (WC), hip circumference, body composition and fasted capillary blood glucose, triglycerides, high-density lipopreotein cholesterol, low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) levels. These cardio-metabolic markers were treated as secondary outcomes. Results Lorry drivers presented an unhealthy cardio-metabolic health profile (median (IQR) systolic BP: 129 (108.5, 164) mm Hg; diastolic BP: 81 (63, 104) mm Hg; BMI: 29 (20, 47) kg/m2; WC: 102 (77.5, 146.5) cm; LDL-C: 3 (1, 6) mmol/L; TC: 4.9 (3, 7.5) mmol/L). 84% were overweight or obese, 43% had type 2 diabetes or prediabetes and 34% had the metabolic syndrome. The subsample of lorry drivers with objective postural data (n=87) accumulated 13 hours/day and 8 hours/day of sedentary behaviour on workdays and non-workdays (pdrivers accrued 12 min/day on workdays and 6 min/day on non-workdays of moderate-to-vigorous PA (MVPA).

      To examine whether yogurt consumption is associated with a healthier dietary pattern and with a better cardio-metabolic risk profile among healthy individuals classified on the basis of their body mass index (BMI). A 91-item food frequency questionnaire, including data on yogurt consumption, was administered to 664 subjects from the INFOGENE study. After principal component analysis, two factors were retained, thus classified as the Prudent and Western dietary patterns. Yogurt was a significant contributor to the Prudent dietary pattern. Moreover, yogurt consumption was associated with lower body weight, waist-to-hip ratio, and waist circumference and tended to be associated with a lower BMI. Consumers had lower levels of fasting total cholesterol and insulin. Consumers of yogurt had a positive Prudent dietary pattern mean score, while the opposite trend was observed in non-consumers of yogurt. Overweight/obese individuals who were consumers of yogurts exhibited a more favorable cardio-metabolic profile characterized by lower plasma triglyceride and insulin levels than non-consumers within the same range of BMI. There was no difference in total yogurt consumption between normal-weight individuals and overweight/obese individuals. However, normal-weight subjects had more daily servings of high-fat yogurt and less daily servings of fat-free yogurt compared to overweight/obese individuals. Being a significant contributor to the Prudent dietary pattern, yogurt consumption may be associated with healthy eating. Also, yogurt consumption may be associated with lower anthropometric indicators and a more beneficial cardio-metabolic risk profile in overweight/obese individuals.

      Obesity is a rising problem among adolescents in modern societies; it results in long-term cardio-metabolic problems. Possible overlooked drivers of obesity and its consequent cardio-metabolic deficits include videogame addiction and the resulting curtailed sleep; both are growing problems among adolescents. The objective of this study is to examine possible associations among these concepts in adolescents, as a means to point to plausible interventions. Data were collected from 94 adolescents who play videogames and are enrolled in outpatient clinics, using surveys, wearable sleep monitors (FitBit), physical exams, and blood tests at three points in time. These data were subjected to structural equation modeling (SEM) analyses and bootstrapping-based mediation testing procedures. Videogame addiction among adolescents was negatively associated with sleep duration (β = -0.24). Sleep duration was negatively associated with obesity (β = -0.30), which in turn was associated with elevated blood pressure (β = 0.26), low high-density lipoprotein cholesterol (β = -0.18), high triglycerides (β = 0.61), and high insulin resistance (β = 0.39). The model explained 36.2% of the variation in sleep duration, 32.7% of the variation in obesity, and between 12.8% and 28.1% of the variation in cardio-metabolic indicators. Post-hoc analyses indicated that curtailed sleep is a possible full mediator of the association between videogame addiction, abdominal obesity and the associated cardio-metabolic deficits. The findings point to possible information systems use lifestyle-health links, which behooves researchers and practitioners to pay closer attention to possible adverse health outcomes of technology-related addictions. Interventions that target problematic video-gaming and sleep should be devised as a possible means for improving adolescents' long-term cardio-metabolic health.

      Full Text Available La gravedad de la infección respiratoria aguda (IRA es mayor en países en desarrollo, sobre todo entre grupos social y económicamente pobres. Las neumonías virales son las más comunes, especialmente en niños. Con el fin de medir algunos factores asociados con formas graves de infección respiratoria baja realizamos un estudio de casos y controles prospectivo y de base hospitalaria en Bogotá entre noviembre de 2000 y agosto de 2001. Los casos fueron niños entre 2 meses y 5 años que llenaban los criterios de la OMS para IRA grave o muy grave. Los controles eran niños con IRA en el mismo rango de edad, que consultaban al mismo hospital y que no presentaban tirajes. Se estudiaron 638 niños entre los 2 meses y los 5 años de edad (277 casos y 361 controles. Los factores más importantes fueron: vivienda en préstamo (OR=2,7; IC95%: 1,06-7,07, compartir la cama (OR=1,88; IC95%: 1,0-3,7, más de 9 personas en la misma casa (OR=1,82; IC95%: 1,0-3,51 y fumadores en la vivienda (OR=1,4; IC95%: 1,0-2,05. Se tomaron 114 muestras nasofaríngeas (niños con 3 días de haber iniciado síntomas y se obtuvieron virus en 98 de ellas, y se identificó el virus sincitial respiratorio en 41,8%, virus influenza A en 3,1% y virus influenza B en 1%. El 100% de los aislamientos positivos para influenza A y B fueron enviados al CDC en Atlanta, donde fueron clasificados como influenza A/PANAMA/2007/99-like e influenza B/SICHUAN/379/99-like, respectivamente.

Material y métodos: Se realizaron mediciones ambientales de polvo de aluminio, tricloroetileno y glicol, estudio alergológico con dichas sustancias además de neumoalergenos y tests epicutáneos con batería estándar europea, análisis de sangre, radiografías de tórax, mediciones de flujo pico y pruebas funcionales respiratorias, test de metacolina y electrocardiograma. Resultados: La medición del flujo pico y el test de hiperreactividad bronquial directo con metacolina fueron negativos. El estudio alergológico de las sustancias expuestas fue negativo detectándose en 3 casos resultados positivos a neumoalergenos. Conclusiones: La negatividad en las mediciones del flujo pico y el test de metacolina estando el trabajador en activo, prácticamente descartarían un cuadro de asma laboral, en la actualidad. No podemos descartar la posibilidad concomitante de un Síndrome de disfunción reactiva de la vía aérea en un momento previo al estudio. En tal caso, la existencia de una hiperreactividad bronquial inicial podría haber cedido sin llegar a objetivarse en la actualidad con metacolina.

      Elevated risk factors for a number of chronic diseases have been identified in lorry drivers. Unhealthy lifestyle behaviours such as a lack of physical activity (PA) and high levels of sedentary behaviour (sitting) likely contribute to this elevated risk. This study behaviourally phenotyped UK lorry drivers' sedentary and non-sedentary behaviours during workdays and non-workdays and examined markers of drivers cardio-metabolic health. A transport company from the East Midlands, UK. A sample of 159 male heavy goods vehicle drivers (91% white European; (median (range)) age: 50 (24, 67) years) completed the health assessments. 87 (age: 50.0 (25.0, 65.0); body mass index (BMI): 27.7 (19.6, 43.4) kg/m 2 ) provided objective information on sedentary and non-sedentary time. Participants self-reported their sociodemographic information. Primary outcomes: sedentary behaviour and PA, assessed over 7 days using an activPAL3 inclinometer. Cardio-metabolic markers included: blood pressure (BP), heart rate, waist circumference (WC), hip circumference, body composition and fasted capillary blood glucose, triglycerides, high-density lipopreotein cholesterol, low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) levels. These cardio-metabolic markers were treated as secondary outcomes. Lorry drivers presented an unhealthy cardio-metabolic health profile (median (IQR) systolic BP: 129 (108.5, 164) mm Hg; diastolic BP: 81 (63, 104) mm Hg; BMI: 29 (20, 47) kg/m 2 ; WC: 102 (77.5, 146.5) cm; LDL-C: 3 (1, 6) mmol/L; TC: 4.9 (3, 7.5) mmol/L). 84% were overweight or obese, 43% had type 2 diabetes or prediabetes and 34% had the metabolic syndrome. The subsample of lorry drivers with objective postural data (n=87) accumulated 13 hours/day and 8 hours/day of sedentary behaviour on workdays and non-workdays (pdrivers accrued 12 min/day on workdays and 6 min/day on non-workdays of moderate-to-vigorous PA (MVPA).

      Full Text Available Obesity is a rising problem among adolescents in modern societies; it results in long-term cardio-metabolic problems. Possible overlooked drivers of obesity and its consequent cardio-metabolic deficits include videogame addiction and the resulting curtailed sleep; both are growing problems among adolescents. The objective of this study is to examine possible associations among these concepts in adolescents, as a means to point to plausible interventions.Data were collected from 94 adolescents who play videogames and are enrolled in outpatient clinics, using surveys, wearable sleep monitors (FitBit, physical exams, and blood tests at three points in time. These data were subjected to structural equation modeling (SEM analyses and bootstrapping-based mediation testing procedures.Videogame addiction among adolescents was negatively associated with sleep duration (β = -0.24. Sleep duration was negatively associated with obesity (β = -0.30, which in turn was associated with elevated blood pressure (β = 0.26, low high-density lipoprotein cholesterol (β = -0.18, high triglycerides (β = 0.61, and high insulin resistance (β = 0.39. The model explained 36.2% of the variation in sleep duration, 32.7% of the variation in obesity, and between 12.8% and 28.1% of the variation in cardio-metabolic indicators. Post-hoc analyses indicated that curtailed sleep is a possible full mediator of the association between videogame addiction, abdominal obesity and the associated cardio-metabolic deficits.The findings point to possible information systems use lifestyle-health links, which behooves researchers and practitioners to pay closer attention to possible adverse health outcomes of technology-related addictions. Interventions that target problematic video-gaming and sleep should be devised as a possible means for improving adolescents' long-term cardio-metabolic health.

      Full Text Available Campo Quijano está a 30 Km. de la ciudad de Salta y cuenta aproximadamente con 8300 habitantes. En el éjido urbano existen dos borateras que constituyen una fuente puntual de contaminación del aire, suelo y aguas. Se estudió la prevalencia de enfermedades respiratorias en la población urbana en el año 2005. Se trabajó con los datos de las planillas de consultas diarias externas del Hospital Francisco Herrera. Se consideraron cuatro grupos de afecciones, seleccionados por la sintomatología y su posible asociación con las emisiones gaseosas de las borateras: Rinitis; Catarro en vías aéreas superiores, Espasmos y Tos irritativa. Se estimó y comparó la prevalencia de las enfermedades por barrio con la prueba de X2 y la de los residuales ajustados de Haberman. Los espasmos y catarros en vías aéreas superiores fueron las afecciones más frecuentes en la población de Campo Quijano. En rinitis no se encontraron diferencias entre barrios. El barrio San Roque presentó las mayores prevalencias en CVAs, espasmos y tos irritativa. Barrios cercanos a las borateras presentaron prevalencias dispares, lo que podría relacionarse con características socio-culturales, sanitarias y económicas, entre otros factores de riesgo, no considerados en este diagnóstico.

      The burden of cardiac side effects in oncology patients will dramatically increase in the near future as a result of the widespread use of anticancer agents affecting the cardiovascular system, the general population aging, the heightened attention in the detection of cardiac toxicity and the absolute gain in terms of overall survival. The relationship between cardiologists and oncologists should therefore be closer leading to the definition of cardio-oncology. The increased number of such patients requires the creation of a dedicated patient assistance program in order to guarantee every patient the possibility of an interdisciplinary and multiprofessional approach. A dedicated care pathway needs a reorganization of internal resources to ensure high standards of care. The proposed pathway is actually active at our institution and has been implemented taking into account available facilities and planned work amount. Our patient cardio-oncology program could be adapted with minimal changes to different hospitals.

      We investigated cardio-respiratory coupling in patients with heart failure by quantification of bidirectional interactions between cardiac (RR intervals) and respiratory signals with complementary measures of time series analysis. Heart failure patients were divided into three groups of twenty, age and gender matched, subjects: with sinus rhythm (HF-Sin), with sinus rhythm and ventricular extrasystoles (HF-VES), and with permanent atrial fibrillation (HF-AF). We included patients with indication for implantation of implantable cardioverter defibrillator or cardiac resynchronization therapy device. ECG and respiratory signals were simultaneously acquired during 20 min in supine position at spontaneous breathing frequency in 20 healthy control subjects and in patients before device implantation. We used coherence, Granger causality and cross-sample entropy analysis as complementary measures of bidirectional interactions between RR intervals and respiratory rhythm. In heart failure patients with arrhythmias (HF-VES and HF-AF) there is no coherence between signals ( p respiratory signal in HF-VES. Cross-sample entropy analysis revealed the strongest synchrony between respiratory and RR signal in HF-VES group. Beside respiratory sinus arrhythmia there is another type of cardio-respiratory interaction based on the synchrony between cardiac and respiratory rhythm. Both of them are altered in heart failure patients. Respiratory sinus arrhythmia is reduced in HF-Sin patients and vanished in heart failure patients with arrhythmias. Contrary, in HF-Sin and HF-VES groups, synchrony increased, probably as consequence of some dominant neural compensatory mechanisms. The coupling of cardiac and respiratory rhythm in heart failure patients varies depending on the presence of atrial/ventricular arrhythmias and it could be revealed by complementary methods of time series analysis.

      The canonical transient receptor potential channels (TRPCs) constitute a series of nonselective cation channels with variable degrees of Ca 2+ selectivity. TRPCs consist of seven mammalian members, TRPC1, TRPC2, TRPC3, TRPC4, TRPC5, TRPC6, and TRPC7, which are further divided into four subtypes, TRPC1, TRPC2, TRPC4/5, and TRPC3/6/7. These channels take charge of various essential cell functions such as contraction, relaxation, proliferation, and dysfunction. This review, organized into seven main sections, will provide an overview of current knowledge about the underlying pathogenesis of TRPCs in cardio/cerebrovascular diseases, including hypertension, pulmonary arterial hypertension, cardiac hypertrophy, atherosclerosis, arrhythmia, and cerebrovascular ischemia reperfusion injury. Collectively, TRPCs could become a group of drug targets with important physiological functions for the therapy of human cardio/cerebro-vascular diseases.

      Full Text Available This cross-sectional study is one of the first to examine and compare the independent associations of objectively measured sedentary time, moderate to vigorous physical activity (MVPA and fitness with cardio-metabolic risk factors. We studied 543 men and women (aged 18–49 years from the NHANES 2003–2004 survey. Sedentary time and MVPA were measured by accelerometry. Fitness was assessed with a submaximal treadmill test. Cardio-metabolic risk factors included: waist circumference (WC, BMI, blood pressure, fasting glucose, HDL- and non HDL cholesterol, triglycerides (TG, and C-reactive protein (CRP. Sedentary time, MVPA and fitness were used as predictors for the cardio-metabolic outcomes in a multiple regression analysis. Standardized regression coefficients were computed. Results show that sedentary time was associated with HDL-cholesterol (β = −0.080, p = 0.05 and TG (β = 0.080, p = 0.03. These results became non-significant after adjustment for MVPA and fitness. MVPA was associated with WC (β = −0.226, BMI (β = −0.239, TG (β = −0.108 and HDL-cholesterol (β = 0.144 (all p < 0.05. These results remained significant after adjustment for sedentary time and fitness. Fitness was associated with WC (β = −0.287, BMI (β = −0.266, systolic blood pressure (β = −0.159, TG (β = −0.092, and CRP (β = −0.130 (all p < 0.05. After adjustment for sedentary time and MVPA these results remained significant. These differences in relative importance of sedentary time, MVPA and fitness on cardio-metabolic-risk are important in the design of prevention programs. In this population, the strength of the associations between MVPA and fitness with cardio-metabolic markers appeared to be similar; both MVPA and fitness showed independent associations with cardio-metabolic risk factors. In contrast, sedentary time showed no independent associations with cardio-metabolic risk after correction for fitness and MVPA.

      Full Text Available Higher protein meals increase satiety and the thermic effect of feeding (TEF in acute settings, but it is unclear whether these effects remain after a person becomes acclimated to energy restriction or a given protein intake. This study assessed the effects of predominant protein source (omnivorous, beef/pork vs. lacto-ovo vegetarian, soy/legume and quantity (10%, 20%, or 30% of energy from protein on appetite, energy expenditure, and cardio-metabolic indices during energy restriction (ER in overweight and obese adults. Subjects were randomly assigned to one protein source and then consumed diets with different quantities of protein (4 weeks each in a randomized crossover manner. Perceived appetite ratings (free-living and in-lab, TEF, and fasting cardio-metabolic indices were assessed at the end of each 4-week period. Protein source and quantity did not affect TEF, hunger, or desire to eat, other than a modestly higher daily composite fullness rating with 30% vs. 10% protein diet (p = 0.03. While the 20% and 30% protein diets reduced cholesterol, triacylglycerol, and APO-B vs. 10% protein (p < 0.05, protein source did not affect cardio-metabolic indices. In conclusion, diets varying in protein quantity with either beef/pork or soy/legume as the predominant source have minimal effects on appetite control, energy expenditure and cardio-metabolic risk factors during ER-induced weight loss.

      Full Text Available Background: Obesity once thought the medical problem of affluent countries now exist in Nigeria and has been described as a time bomb for the future explosion in the frequency of cardio-metabolic diseases. The most deleterious health consequences of obesity are on the cardiovascular system and associated disorder of lipid and glucose homeostasis. Aim: This study was designed to determine the magnitude of obesity and its cardio-metabolic co-morbidities among adult Nigerians in a primary care clinic of a tertiary hospital South-Eastern, Nigeria. Materials and Methods: A cross-sectional study carried out on 2391 adult Nigerians who were assessed for obesity using body mass index (BMI criterion. 206 patients who had BMI ΃30kg/m 2 were screened for cardio-metabolic co-morbidities. The data collected included basic demographic variables, weight, height, blood pressure; fasting plasma glucose and lipid profile. Results: The prevalence of obesity was 8.6%. Grade I obesity (67.5% was the most common pattern; others included grade II obesity (23.3% and grade III obesity (9.2%. Hypertension (42.7% was the most common cardio-metabolic morbidity. Others included low HDL-cholesterol (22.8%, diabetes mellitus (15.1%, high triglyceride (12.6%, high total cholesterol (9.2%, and high LDL-cholesterol (6.8%. Conclusion: Obesity and its cardio-metabolic morbidities exist among the study population. Anthropometric determination of obesity and screening for its associated cardio-metabolic co-morbidities should constitute clinical targets for intervention in primary care clinics.

      Cardio- and cerebro-vascular diseases are two leading causes of death and long-term disability in postmenopausal women. The acute fall of estrogen in menopause is associated with increased cardiovascular risk. The relative contribution of androgen to this risk is also being recognized. The use of more sensitive assays for estradiol measurement and the study of receptor and carrier protein gene polymorphisms have provided some new information on the clinical relevance of endogenous sex steroids. We provide an update on the role of endogenous sex steroids on cardio- and cerebro-vascular disease in the postmenopausal period. We performed a PubMed search using the terms 'endogenous estrogen', 'androgen', 'cardiovascular disease', 'cerebro-vascular disease', 'stroke', 'carotid artery disease', and 'subclinical atherosclerosis'. The majority of studies show a beneficial effect of endogenous estrogen on the vasculature; however, there are a few studies reporting the contrary. A significant body of literature has reported associations of endogenous estrogen and androgen with early markers of atherosclerosis and metabolic parameters. Data on the relevance of endogenous sex steroids in heart disease and stroke are inconclusive. Most studies support a beneficial role of endogenous estrogens and, probably, an adverse effect of androgens in the vasculature in postmenopausal women. However, the described associations may not always be considered as causal. It is possible that circulating estrogen might represent a marker of general health status or alternatively reflect the sum of endogenous androgens aromatized in the periphery. Elucidating the role of sex steroids in cardio- and cerebro-vascular disease remains an interesting field of future research.

    15. Cardio-respiratory development in bird embryos: new insights from a venerable animal model

      Directory of Open Access Journals (Sweden)

      Warren W. Burggren

      Full Text Available ABSTRACT The avian embryo is a time-honored animal model for understanding vertebrate development. A key area of extensive study using bird embryos centers on developmental phenotypic plasticity of the cardio-respiratory system and how its normal development can be affected by abiotic factors such as temperature and oxygen availability. Through the investigation of the plasticity of development, we gain a better understanding of both the regulation of the developmental process and the embryo's capacity for self-repair. Additionally, experiments with abiotic and biotic stressors during development have helped delineate not just critical windows for avian cardio-respiratory development, but the general characteristics (e.g., timing and dose-dependence of critical windows in all developing vertebrates. Avian embryos are useful in exploring fetal programming, in which early developmental experiences have implications (usually negative later in life. The ability to experimentally manipulate the avian embryo without the interference of maternal behavior or physiology makes it particularly useful in future studies of fetal programming. The bird embryo is also a key participant in studies of transgenerational epigenetics, whether by egg provisioning or effects on the germline that are transmitted to the F1 generation (or beyond. Finally, the avian embryo is heavily exploited in toxicology, in which both toxicological testing of potential consumer products as well as the consequences of exposure to anthropogenic pollutants are routinely carried out in the avian embryo. The avian embryo thus proves useful on numerous experimental fronts as an animal model that is concurrently both of adequate complexity and sufficient simplicity for probing vertebrate cardio-respiratory development.

      Full Text Available BACKGROUND: The workplace is a main setting for prolonged sitting for some occupational groups. Convincing evidence has recently accumulated on the detrimental cardio-metabolic health effects of leisure-time sitting. Yet, much less is known about occupational sitting, and the potential health risk attached compared to leisure-time sitting. OBJECTIVE: To explore the separate and joint associations of occupational and leisure-time sitting with cardio-metabolic risk factors in working adults. METHODS: All working adults (N = 2544 from the Health2006, a Danish population-based study, were included in this cross-sectional study. Participants reported hours of sitting during work, during leisure-time along with socio-demographic and behavioral characteristics, including physical activity. Cardio-metabolic risk factors (waist circumference, body mass index, body fat percentage, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, insulin, hemoglobin A1c and plasma glucose were measured. Associations were explored by linear regression for leisure-time, occupational, and overall sitting time. RESULTS: Statistically significant (p<.05 detrimental associations of leisure-time sitting were observed with all cardio-metabolic risk factors, except hemoglobin A1c and plasma glucose. Similarly, occupational sitting time was significantly detrimentally associated with HDL cholesterol, triglycerides, and insulin. For categories of sitting time, a joint adverse association of sitting much during both work-time and leisure-time was observed. CONCLUSION: The associations of occupational sitting time with cardio-metabolic risk factors were fewer and weaker compared to leisure-time sitting. Yet, the joint associations of occupational and leisure-time sitting with cardio-metabolic risk factors were higher than the separate. Our findings amplify the need for further focus in this area prior to making assumptions about equivalent health risks across

      We present the initial 2-year results of CardioCel® patch (Admedus Regen Pty Ltd, Perth, WA, Australia) implantation in paediatric patients with congenital heart diseases. This was a single-centre retrospective study with prospectively collected data of all patients aged 18 years and under operated for congenital heart disease. The patch was introduced in 2014, with clinical practice committee approval and a special consent in case of an Ozaki procedure. Standard follow-up was performed with systematic clinical exams and echocardiograms. In case of reoperation or graft failure, the patch was removed and sent for a histological examination. Between March 2014 and April 2016, 101 patients had surgical repair using a CardioCel patch. The mean age was 22 (±36.3) months, and the mean weight was 9.7 (±10.3) kg. No infections and no intraoperative implantation difficulties were associated with the patch. The median follow-up period was 212 (range 4-726) days. The overall 30-day postoperative mortality was 3.8% (n = 4), none of which were related to graft failure. Five children were reoperated because of graft failure, 4 of whom had the patch implanted for aortic and were aged less than 10 days. The indications for patch implantation in the aortic position were aortopulmonary window, truncus arteriosus, coarctation and aortic arch hypoplasia repair. The median time between the first and the second operation for graft failure was 245 (range 5-480) days. Our experience shows that the patch is well tolerated in the septal, valvar and pulmonary artery positions. However, we experienced graft failures in infants in the aortic position. © The Author 2017. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery.

      Full Text Available The predictive relationship between muscular strength and endurance and cardio-metabolic health, independent from aerobic fitness, is not clear in disadvantaged Hispanic children. The purpose of this study was to examine the predictive relationship between muscular strength and endurance and clustered cardio-metabolic risk, controlling for aerobic fitness, in Hispanic children from low-income schools. Participants were 320 Hispanic children (Mean age = 10.1 ± 1.1 years; 164 girls, 156 boys recruited during the 2014–2015 and 2015–2016 academic years from five low-income schools from the state of Utah in the U.S. Muscular strength and endurance was assessed using the push-up and curl-up tests and estimated VO2 Peak was calculated from the Progressive Aerobic Cardiovascular Endurance Run. A clustered metabolic syndrome composite score (MetS was calculated from cardio-metabolic health measurements consisting of HDL cholesterol, triglycerides, waist circumference, blood glucose, and mean arterial pressure (MAP. Multi-level general linear mixed effects models were used to examine the predictive relationship between muscular strength and endurance and MetS, controlling for the effect of aerobic fitness and the clustering of children within classrooms and schools. Children who were in the middle and upper tertiles for muscular strength and endurance associated with a lower (more favorable MetS score (middle tertile: β = −2.59, 95% C.I. [−4.23, −0.95], p < 0.05; upper tertile: β = −1.57, 95% C.I. [−3.20, −0.16], p < 0.05. The results suggest that higher levels of muscular strength and endurance relate to lower cardio-metabolic risk, independent of aerobic fitness, in Hispanic children from low-income schools.

      Although the orthostatic cardio-respiratory response is primarily mediated by the baroreflex, studies have shown that vestibular cues also contribute in both humans and animals. We have demonstrated a visually mediated response to illusory tilt in some human subjects. Blood pressure, heart and respiration rate, and lung volume were monitored in 16 supine human subjects during two types of visual stimulation, and compared with responses to real passive whole body tilt from supine to head 80 degrees upright. Visual tilt stimuli consisted of either a static scene from an overhead mirror or constant velocity scene motion along different body axes generated by an ultra-wide dome projection system. Visual vertical cues were initially aligned with the longitudinal body axis. Subjective tilt and self-motion were reported verbally. Although significant changes in cardio-respiratory parameters to illusory tilts could not be demonstrated for the entire group, several subjects showed significant transient decreases in mean blood pressure resembling their initial response to passive head-up tilt. Changes in pulse pressure and a slight elevation in heart rate were noted. These transient responses are consistent with the hypothesis that visual-vestibular input contributes to the initial cardiovascular adjustment to a change in posture in humans. On average the static scene elicited perceived tilt without rotation. Dome scene pitch and yaw elicited perceived tilt and rotation, and dome roll motion elicited perceived rotation without tilt. A significant correlation between the magnitude of physiological and subjective reports could not be demonstrated.

Las manifestaciones clínicas producidas por el hMPV son indistinguibles de aquellas provocadas por los virus respiratorios clásicamente conocidos, y varían desde infección asintomática hasta neumonía complicada. Por otro lado, se han descrito casos de exacerbación de asma bronquial asociados a la infección con hMPV. En este trabajo se describe el caso de un niño hospitalizado que presentó una crisis asmática bronquial severa con sospecha de una infección viral asociada. Por el test de inmunofluorescencia indirecta no se detectaron virus sincicial respiratorio (VSR, adenovirus, virus influenza a - b ni virus parainfluenza 1, 2 y 3. En un intento por detectar la presencia de hMPV, se realizó una RT-PCR para la amplificación de los genes N y F con resultado positivo. Conforme a nuestro conocimiento, esta sería la primera descripción de un caso de exacerbación de asma asociado a hMPV en nuestra región. Los resultados de este estudio serían similares a los reportados por otros autores, quienes postulan que, a semejanza de lo que ocurre con el VSR, una infección por hMPV puede gatillar una enfermedad respiratoria crónica, como el asma.Human Metapneumovirus (hMPV is a recently reported agent of acute infection in the respiratory tract.

      Full Text Available Abstract Objectives Pericardial tamponade after cardiac surgery is difficult to diagnose, thereby rendering timing of rethoracotomy hard. We aimed at identifying factors predicting the outcome of surgery for suspected tamponade after cardio-thoracic surgery, in the intensive care unit (ICU. Methods Twenty-one consecutive patients undergoing rethoracotomy for suspected pericardial tamponade in the ICU, admitted after primary cardio-thoracic surgery, were identified for this retrospective study. We compared patients with or without a decrease in severe haemodynamic compromise after rethoracotomy, according to the cardiovascular component of the sequential organ failure assessment (SOFA score. Results A favourable haemodynamic response to rethoracotomy was observed in 11 (52% of patients and characterized by an increase in cardiac output, and less fluid and norepinephrine requirements. Prior to surgery, the absence of treatment by heparin, a minimum cardiac index 2 and a positive fluid balance (> 4,683 mL were predictive of a beneficial haemodynamic response. During surgery, the evacuation of clots and > 500 mL of pericardial fluid was associated with a beneficial haemodynamic response. Echocardiographic parameters were of limited help in predicting the postoperative course, even though 9 of 13 pericardial clots found at surgery were detected preoperatively. Conclusion Clots and fluids in the pericardial space causing regional tamponade and responding to surgical evacuation after primary cardio-thoracic surgery, are difficult to diagnose preoperatively, by clinical, haemodynamic and even echocardiographic evaluation in the ICU. Only absence of heparin treatment, a large positive fluid balance and low cardiac index predicted a favourable haemodynamic response to rethoracotomy. These data might help in deciding and timing of reinterventions after primary cardio-thoracic surgery.

      2013-11-01

      Full Text Available The clustering of cardio-metabolic risk factors, either when called metabolic syndrome (MetS or not, substantially increases the risk of cardiovascular disease (CVD and causes mortality. One of the possible mechanisms for this clustering's adverse effect is an increase in arterial stiffness (AS, and in high central aortic blood pressure (CABP, which are significant and independent CVD risk factors. Arterial hypertension was connected to AS long ago; however, other MetS components (obesity, dyslipidaemia, dysglycaemia or MetS associated abnormalities not included in MetS diagnostic criteria (renal dysfunction, hyperuricaemia, hypercoaglutability, menopause, non alcoholic fatty liver disease, and obstructive sleep apnea have been implicated too. We discuss the evidence connecting these cardio-metabolic risk factors, which negatively affect AS and finally increase CVD risk. Furthermore, we discuss the impact of possible lifestyle and pharmacological interventions on all these cardio-metabolic risk factors, in an effort to reduce CVD risk and identify features that should be taken into consideration when treating MetS patients with or without arterial hypertension.

      Research in to short-term cardio-respiratory changes in animals in reaction to a psychological stressor typically describes increases in rate of oxygen consumption (V̇(O2)) and heart rate. Consequently, the broad consensus is that they represent a fundamental stressor response generalizable across adult species. However, movement levels can also change in the presence of a stressor, yet studies have not accounted for this possible confound on heart rate. Thus the direct effects of psychological stressors on the cardio-respiratory system are not resolved. We used an innovative experimental design employing accelerometers attached to king penguins (Aptenodytes patagonicus) to measure and thus account for movement levels in a sedentary yet free-to-move animal model during a repeated measures stress experiment. As with previous studies on other species, incubating king penguins (N = 6) exhibited significant increases in both V̇(O2) and heart rate when exposed to the stressor. However, movement levels, while still low, also increased in response to the stressor. Once this was accounted for by comparing periods of time during the control and stress conditions when movement levels were similar as recorded by the accelerometers, only V̇(O2) significantly increased; there was no change in heart rate. These findings offer evidence that changing movement levels have an important effect on the measured stress response and that the cardio-respiratory response per se to a psychological stressor (i.e. the response as a result of physiological changes directly attributable to the stressor) is an increase in V̇(O2) without an increase in heart rate.

      The effect of BMI defined obesity on cardio-metabolic features and biomarkers of oxidative stress and inflammation in patients with nascent metabolic Syndrome (MetS) is poorly defined. Hence the aim of this study was to examine the effect of increasing obesity on the cardio metabolic risk profile, pro-oxidant state and pro-inflammatory features in nascent MetS patients without Diabetes or CVD. MetS was diagnosed by ATPIII criteria using waist circumference (WC) as the measure of adiposity. Patients (n=58) were stratified into overweight, obese and extreme obesity groups using BMI cut offs of 25-29.9, 30-39.9kg/m 2 and ≥40kg/m 2 and cardio-metabolic features, circulating and cellular biomarkers of oxidative stress and inflammation were determined and correlated with BMI. None of the main cardio-metabolic features including blood pressure, blood glucose, HDL-cholesterol, triglycerides, HOMA-IR, free fatty acids were increased with increasing BMI. Also none of the biomarkers of oxidative stress (ox-LDL, nitrotyrosine and monocyte superoxide anion release) were increased with increasing BMI. However, significant increase in hsCRP, the soluble TNFR1 and sTNFR2 and leptin, were observed with increasing adiposity. Other inflammatory bio-mediators (IL-1β, IL-6, IL-8, MCP-1, Toll-like receptors 2-4), endotoxin, LBP, sCD14 and HMGB1, adiponectin, and chemerin did not show significant increases with increasing BMI. Leptin, hsCRP, sTNFR1, and sTNFR2 correlated significantly with BMI. In conclusion, capturing the cardio-metabolic cluster of MetS that predisposed to both increased risk of diabetes and CVD, using waist circumference, as one of the 5 diagnostic criteria is sufficient and BMI does not appear to afford any major incremental benefit on the cardio-metabolic risk factors, increased oxidative stress and the majority of both cellular and circulating biomarkers of inflammation.

      Various studies show major regional differences in the prevalence of cardio-vascular disease morbidity and mortality, both in Europe and within European countries. In Austria, these differences are documented by an East-West gradient with declining morbidity and mortality rates when moving from the East to the West of the country. It was the aim of this study to analyse if, and to what extent, socio-demographic and socio-economic determinants, social resources and health behaviour can contribute to the clarification of this East-West gradient by conducting secondary analyses of an existing Austrian health dataset. The data were analysed using bivariate analyses, as well as univariate and multivariate logistic regression models. These analyses revealed significant East-West gradients for various risk factors, as well as socio-demographic and socio-economic health determinants. There was a gradual decrease of hypertension, diabetes mellitus, obesity, and psycho-social discomfort in both sexes, with the highest prevalences in those Austrian regions with the highest cardio-vascular mortality and a stepwise decrease to the regions with the lowest cardio-vascular mortality. Controlling for educational level significantly raised the odds for diabetes, hypertension and obesity. In the results of the multivariate analyses, factors that significantly and independently predicted diabetes mellitus were geographic location, psycho-social discomfort, lack of physical exercise, and age in both sexes. For women these factors additionally included a low educational level, lack of social support, and being born abroad. Our study shows a clear gradual decline of cardio-vascular mortality and some of its risk factors from East to West in Austria. Concerning these risk factors, the geographic region and psycho-social discomfort showed the greatest association with diabetes mellitus, hypertension, and obesity. Hence, they contribute to the explanation of the variance in spatial cardio

      Los rotavirus son la causa más común de gastroenteritis severa en niños menores de cinco años, ocasionando episodios diarreicos agudos responsables de 454.000 a 705.000 muertes anuales a nivel mundial.
       
      Aunque la frecuencia de infección con rotavirus es muy similar a través del mundo, en los países en desarrollo la gastroenteritis rotaviral es la mayor causa de muerte infantil. 
       
      La diarrea rotaviral severa cursa con vómito y fiebre, produciendo deshidratación con shock, desbalance electrolítico, y muerte si esta no es tratada. En los países desarrollados, la infección rotaviral es responsable del 30 - 50% de las hospitalizaciones debidas a gastroenteritis en menores de 5 años. 
      Además, los rotavirus son una causa importante en la gastroenteritis nosocomial.

      Higher protein meals increase satiety and the thermic effect of feeding (TEF) in acute settings, but it is unclear whether these effects remain after a person becomes acclimated to energy restriction or a given protein intake. This study assessed the effects of predominant protein source (omnivorous, beef/pork vs. lacto-ovo vegetarian, soy/legume) and quantity (10%, 20%, or 30% of energy from protein) on appetite, energy expenditure, and cardio-metabolic indices during energy restriction (ER) in overweight and obese adults. Subjects were randomly assigned to one protein source and then consumed diets with different quantities of protein (4 weeks each) in a randomized crossover manner. Perceived appetite ratings (free-living and in-lab), TEF, and fasting cardio-metabolic indices were assessed at the end of each 4-week period. Protein source and quantity did not affect TEF, hunger, or desire to eat, other than a modestly higher daily composite fullness rating with 30% vs. 10% protein diet (p = 0.03). While the 20% and 30% protein diets reduced cholesterol, triacylglycerol, and APO-B vs. 10% protein (p appetite control, energy expenditure and cardio-metabolic risk factors during ER-induced weight loss.

      Full Text Available The association between dental and cardio-vascular diseases is essential as both are highly prevalent. Finding a possible causal relation between cardiovascular disease and chronic periodontal pathology, known to cause tooth loss, is therefore essential. The existence of some risk factors, such as smoking, bacterial infections, malnutrition and nutritional deficiencies, may explain the associations observed between cardio-vascular and oral pathologies. In the case of dental diseases, acceleration of atherosclerosis is supported by the role played by infections. The study – performed between 2008-2009 – analyzed 45 cases, selected from the patients hospitalized in the Medical Clinics of the Military Hospital of Ia[i. The patients included in the study suffered from arterial hypertension (HTA, cardiac insufficiency, ischemic cardiopathy, pectoral angina and subacute infectious endocarditis. All were subjected to a stomatological examination, for establishing their dental hygiene, the stomatological diseases they had had and the treatments performed. There are several ways in which infections of the oral cavity lead to cardiovascular disease. These include: transitory bacteriemia; inflammation and vascular lesions; diet and smoking.

      Several studies have shown that oxidative stress and cell damage can occur at very early stages of diazinon (DZN) exposure. The present study was designed to determine the beneficial effect of thymoquinone (Thy), the main component of Nigella sativa (black seed or black cumin), against DZN cardio-toxicity in rats. In the present experimental study, 48 male Wistar rats were randomly divided into six groups: control (corn oil gavages), DZN gavages (20 mg/kg/day), Thy gavages (10 mg/kg/day) and Thy + DVN gavages (2.5, 5 and 10 mg/kg/day). Treatments were continued for 28 days, then the animals were anesthetized by ether and superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), lactate dehydrogenize (LDH) and glutathione peroxide (GPX) activity was evaluated. In addition, glutathione (GSH) and malondialdehyde (MDA) the heart tissue and creatinephosphokinase-MB (CPK-MB) and troponin (TPI) levels and cholinesterase activity in the blood were evaluated. DZN-induced oxidative damage and elevated the levels of the cardiac markers CK-MB, TPI, MDA and LDH and decreased SOD, CAT and cholinesterase activity and GSH level compared with the control group. Treatment with Thy reduced DZN cardio-toxicity and cholinesterase activity. The success of Thy supplementation against DZN toxicity can be attributed to the antioxidant effects of its constituents. Administration of Thy as a natural antioxidant decreased DZN cardio-toxicity and improved cholinesterase activity in rats through the mechanism of free radical scavenging.

      Assessment of adiposity using dual energy x-ray absorptiometry (DXA) has been considered more advantageous in comparison to anthropometry for predicting cardio-metabolic risk in the older population, by virtue of its ability to distinguish total and regional fat. Nonetheless, there is increasing uncertainty regarding the relative superiority of DXA and little comparative data exist in young adults. This study aimed to identify which measure of adiposity determined by either DXA or anthropometry is optimal within a range of cardio-metabolic risk factors in young adults. 1138 adults aged 20 years were assessed by DXA and standard anthropometry from the Western Australian Pregnancy Cohort (Raine) Study. Cross-sectional linear regression analyses were performed. Waist to height ratio was superior to any DXA measure with HDL-C. BMI was the superior model in relation to blood pressure than any DXA measure. Midriff fat mass (DXA) and waist circumference were comparable in relation to glucose. For all the other cardio-metabolic variables, anthropometric and DXA measures were comparable. DXA midriff fat mass compared with BMI or waist hip ratio was the superior measure for triglycerides, insulin and HOMA-IR. Although midriff fat mass (measured by DXA) was the superior measure with insulin sensitivity and triglycerides, the anthropometric measures were better or equal with various DXA measures for majority of the cardio-metabolic risk factors. Our findings suggest, clinical anthropometry is generally as useful as DXA in the evaluation of the individual cardio-metabolic risk factors in young adults.

      Full Text Available The cardiac component of cardio-respiratory polysomnography is covered by ECG and heart rate recordings. However their evaluation is often underrepresented in summarizing reports. As complements to EEG, EOG, and EMG, these signals provide diagnostic information for autonomic nervous activity during sleep. This review presents major methodological developments in sleep research regarding heart rate, ECG and cardio-respiratory couplings in a chronological (historical sequence. It presents physiological and pathophysiological insights related to sleep medicine obtained by new technical developments. Recorded nocturnal ECG facilitates conventional heart rate variability analysis, studies of cyclical variations of heart rate, and analysis of ECG waveform. In healthy adults, the autonomous nervous system is regulated in totally different ways during wakefulness, slow-wave sleep, and REM sleep. Analysis of beat-to-beat heart-rate variations with statistical methods enables us to estimate sleep stages based on the differences in autonomic nervous system regulation. Furthermore, up to some degree, it is possible to track transitions from wakefulness to sleep by analysis of heart-rate variations. ECG and heart rate analysis allow assessment of selected sleep disorders as well. Sleep disordered breathing can be detected reliably by studying cyclical variation of heart rate combined with respiration-modulated changes in ECG morphology (amplitude of R wave and T wave.

      In modern medicine the well structured patient data set, fast access to it and reporting capability become an important question. With the dynamic development of information technology (IT) such question is solved via building electronic patient record (EPR) archives. We then obtain fast access to patient data, diagnostic and treatment protocols etc. It results in more efficient, better and cheaper treatment. The aim of the work was to design a uniform Electronic Patient Record, implemented in cardio.net system for telecardiology allowing the co-operation among regional hospitals and reference centers. It includes questionnaires for demographic data and questionnaires supporting doctor's work (initial diagnosis, final diagnosis, history and physical, ECG at the discharge, applied treatment, additional tests, drugs, daily and periodical reports). The browser is implemented in EPR archive to facilitate data retrieval. Several tools for creating EPR and EPR archive were used such as: XML, PHP, Java Script and MySQL. The separate question is the security of data on WWW server. The security is ensured via Security Socket Layer (SSL) protocols and other tools. EPR in Cardio.net system is a module enabling the co-work of many physicians and the communication among different medical centers.

      Favorable versus detrimental cardiovascular responses to intermittent hypoxia conditioning (IHC) are heavily dependent on experimental or pathological conditions, including the duration, frequency and intensity of the hypoxia exposures. Recently, we demonstrated that a program of moderate, normobaric IHC (FIO2 9.5-10% for 5-10 min/cycle, with intervening 4 min normoxia, 5-8 cycles/day for 20 days) in dogs afforded robust cardioprotection against infarction and arrhythmias induced by coronary artery occlusion-reperfusion, but this protection has not been verified in other species. Accordingly, in this investigation cardio- as well as vasoprotection were examined in male Wistar rats completing the normobaric IHC program or a sham program in which the rats continuously breathed atmospheric air. Myocardial ischemia and reperfusion (IR) was imposed by occlusion and reperfusion of the left anterior descending coronary artery in in situ experiments and by subjecting isolated, perfused hearts to global ischemia-reperfusion. Cardiac arrhythmias and myocardial infarct size were quantified in in situ experiments. Endothelial function was evaluated from the relaxation to acetylcholine of norepinephrine-precontracted aortic rings taken from in situ IR experiments, and from the increase in coronary flow produced by acetylcholine in isolated hearts. IHC sharply reduced cardiac arrhythmias during ischemia and decreased infarct size by 43% following IR. Endothelial dysfunction in aorta was marked after IR in sham rats, but not significant in IHC rats. Similar findings were found for the coronary circulations of isolated hearts. These findings support the hypothesis that moderate, normobaric IHC is cardio- and vasoprotective in a rat model of IR.

      las etiologías más frecuentes se localizan a nivel colónico. El objetivo es analizar el manejo diagnóstico-terapéutico de las HDB severas cuya etiología se localizaba en el intestino delgado. Pacientes y métodos: entre 1975 y marzo del 2002 ingresaron en nuestro servicio 12 HDB severas originadas en el intestino delgado. Todos consultaron por rectorragia franca, precisando al menos transfusión de 3 unidades de concentrados de hematíes. La edad media fue de 54 ± 21 años, el 58% eran mujeres, y el 83% había presentado cuadros previos de HDB. Resultados: en once casos (92% se realizó una endoscopia digestiva alta y baja urgente no objetivando el origen del sangrado. La arteriografía se indicó en 7 pacientes (58%, localizando en 5 de ellos el sangrado. En dos casos se hizo una gammagrafía mostrando en uno un divertículo de Meckel y en el otro fue normal. Todos se intervinieron, 8 (67% de urgencias, encontrándose un tumor en 9 casos y un divertículo de Meckel en 3, realizándose resección de todas las lesiones. La histología informó de leiomioma en 7 casos, de divertículo de Meckel en 3, de leiomioblastoma en 1 y de angioma en el caso restante. Tras un seguimiento medio de 132 ± 75 meses, fue éxitus el leiomioblastoma, y recidivó el angioma, el cual fue embolizado radiológicamente con éxito. Conclusiones: la HDB severa de origen en intestino delgado debe considerarse como posibilidad etiológica cuando la endoscopia digestiva no objetiva el origen del sangrado, siendo la arteriografía una técnica diagnóstica útil para localizar el sangrado. La cirugía supone el tratamiento definitivo del proceso, confirma la etiología, y descarta la presencia de malignidad.

      Full Text Available Assessment of adiposity using dual energy x-ray absorptiometry (DXA has been considered more advantageous in comparison to anthropometry for predicting cardio-metabolic risk in the older population, by virtue of its ability to distinguish total and regional fat. Nonetheless, there is increasing uncertainty regarding the relative superiority of DXA and little comparative data exist in young adults. This study aimed to identify which measure of adiposity determined by either DXA or anthropometry is optimal within a range of cardio-metabolic risk factors in young adults.1138 adults aged 20 years were assessed by DXA and standard anthropometry from the Western Australian Pregnancy Cohort (Raine Study. Cross-sectional linear regression analyses were performed. Waist to height ratio was superior to any DXA measure with HDL-C. BMI was the superior model in relation to blood pressure than any DXA measure. Midriff fat mass (DXA and waist circumference were comparable in relation to glucose. For all the other cardio-metabolic variables, anthropometric and DXA measures were comparable. DXA midriff fat mass compared with BMI or waist hip ratio was the superior measure for triglycerides, insulin and HOMA-IR.Although midriff fat mass (measured by DXA was the superior measure with insulin sensitivity and triglycerides, the anthropometric measures were better or equal with various DXA measures for majority of the cardio-metabolic risk factors. Our findings suggest, clinical anthropometry is generally as useful as DXA in the evaluation of the individual cardio-metabolic risk factors in young adults.

      Full Text Available Increased prevalence of overweight and obesity, diabetes, hypertension, and other cardio metabolic risks has become a public health concern in China, a country undergoing nutrition transition. We investigated the dietary pattern during 1991–2011 and its association with these risks in a longitudinal study among adults; Adults in The China Health and Nutrition Survey were included. Three-day food consumption was collected by 24 h recall method. Anthropometric measures, blood pressure, fasting blood glucose and lipids was collected in 2009. Dietary pattern was generated using principal components analysis. The associations between dietary pattern and cardio metabolic risk were assessed with generalized linear regression adjusted for age, sex, and social economic status (SES. “Traditional” pattern loaded with rice, meat, and vegetables, and “Modern” pattern had high loadings of fast food, milk, and deep-fried food. “Traditional” pattern was inversely associated with cardio metabolic risks, with linear slopes ranging from −0.15 (95% confidence interval (CI: −0.18, −0.12 for hypertension to −0.67 (95% CI: −0.73, −0.60 for impaired glucose control. “Modern” pattern was associated positively with those factors, with slopes ranging 0.10 (95% CI: 0.04, 0.17 for high cholesterol to 0.42 (95% CI: 0.35, 0.49 for impaired glucose control. Dietary patterns were associated with cardio metabolic risk in Chinese adults.

      Full Text Available Marine omega-3 polyunsaturated fatty acids (n-3 PUFA are important nutrients during periods of rapid growth and development in utero and infancy. Maternal health and risk factors play a crucial role in birth outcomes and subsequently offspring cardio-metabolic health. Evidence from observational studies and randomized trials have suggested a potential association of maternal intake of marine n-3 PUFAs during pregnancy with pregnancy and birth outcomes. However, there is inconsistency in the literature on whether marine n-3 PUFA supplementation during pregnancy can prevent maternal complications of pregnancy. This narrative literature review summarizes recent evidence on observational and clinical trials of marine n-3 PUFA intake on maternal risk factors and effects on offspring cardio-metabolic health. The current evidence generally does not support a role of maternal n-3 PUFA supplementation in altering the incidence of gestational diabetes, pregnancy-induced hypertension, or pre-eclampsia. It may be that benefits from marine n-3 PUFA supplementation are more pronounced in high-risk populations, such as women with a history of complications of pregnancy, or women with low marine n-3 PUFA intake. Discrepancies between studies may be related to differences in study design, dosage, fatty acid interplay, and length of treatment. Further prospective double-blind studies are needed to clarify the impact of long-chain marine n-3 PUFAs on risk factors for cardio-metabolic disease in the offspring.

      The aims to investigate the different protective effects of valsartan and benazepril when combined with atorvastatin in the cardio-renal functions of cardio-renal syndrome (CRS) patients. A total of 200 early CRS patients were enrolled in the present study, including 104 males and 96 females, with an average age of 62.2 ± 7.7 years. The same group of patients were set as the control group prior to treatment, and then randomly divided into two groups; the A group was treated with valsartan (80 mg/d) and atorvastatin (20 mg/d); the B group was treated with benazepril (10 mg/d) and atorvastatin (20 mg/d). The treatment period was 24 months. The clinical efficacy and clinical events were observed and the following parameters of each patient were measured before and after treatment: 24h urine protein; creatinine clearance; serum brain natriuretic peptide (BNP); high sensitivity C-reactive protein (hsCRP); blood lipid level; liver function and ejection fraction (EF) value. Compared with the control group, the clinical symptoms of the treatment groups were improved with decreased blood lipid levels, significantly decreased serum BNP and hsCRP levels and significantly increased EF values and creatinine clearance rates (p benazepril effectively improved the cardio-renal functions of early CRS patients. There was no significant difference between the two treatments however, valsartan appeared to be better tolerated by patients.

      In the Republic of Korea Air Force, the health of pilots is strictly supervised, but there is comparatively not enough interest in aircraft mechanics' health. Among mechanics, who are heavily involved in military aircraft maintenance, the occurrence of sudden cardio-cerebrovascular diseases (CCVDs) is a possible risk factor during the maintenance process, which should be performed perfectly. We performed health examinations on 2123 male aircraft pilots and 1271 aircraft mechanics over 30 yr of age and determined the prevalence of metabolic syndrome (MetS), an important risk factor for CCVDs. The prevalence of MetS in the aircraft mechanics (21.3%) was significantly higher than in the pilots (12.6%), and the gap in prevalence tended to grow as age increased. Among aircraft mechanics in their 30s and 40s, the prevalence of MetS was lower than in the general population. However, the prevalence of MetS among aircraft mechanics in their 50s (36.0%) was similar to that in the general population (35.7%). Systematic health management is needed for aircraft mechanics for aviation safety and for the maintenance of military strength via the prevention of CCVDs.Kim M-B, Kim H-J, Kim S-H, Lee S-H, Lee S-H, Park W-J.

      Cardiovascular toxicity has become a challenging issue during cancer therapy. Nonetheless, there is a lack of consensual guidelines for their management. We aimed to determine the current practices of oncologists regarding cardiovascular toxicity related to anthracyclines, trastuzumab and angiogenic inhibitors and to gather their opinions on the development of cardio-oncology programs. A cross-sectional declarative study was submitted to French oncologists in the form of an individual, structured questionnaire. A total of 303 oncologists responded to the survey. Ninety-nine percent of oncologists prescribed cardiotoxic therapies, including anthracyclines (83%), trastuzumab (51%) and other angiogenic inhibitors (64%). The method adopted for managing cardiovascular toxicity was based on guidelines from expert oncology societies for only 35% of oncologists. None was aware of recommendations from expert cardiology societies. Prescription of pre-, peri- and post-therapy cardiovascular assessment was inconsistent and significantly less frequent for all classes of angiogenic inhibitors than for anthracyclines and trastuzumab (Poncology programs development. Practices of oncologists are disparate in the field of cardiovascular toxicity. This finding underlines the complexity of managing many different situations and the need for distribution of formal guidelines from oncology and cardiology expert societies. The development of personalized cardio-oncology programs seems essential. Copyright © 2017 Elsevier B.V. All rights reserved.

Modelar la variabilidad en el número de consultas infantiles diarias por motivos respiratorios como consecuencia de los cambios diarios en los niveles de contaminación ambiental, observada en los servicios de urgencias y medicina familiar de un hospital de especialidades del Instituto Mexicano del Seguro Social ubicado en la zona suroeste de la Ciudad de México durante 1993. Material y métodos. Se estudió la correlación entre la presencia de infecciones respiratorias altas y bajas con la exposición a ozono y bióxido de nitrógeno. Para modelar esta asociación se utilizó la técnica de regresión Poisson aplicada sobre modelos de riesgo lineal y no lineal con periodos de latencia entre las mediciones ambientales y la consulta de uno, dos y tres días, así como el promedio de las mediciones de los tres, cinco y siete días previos a la consulta. Resultados. El modelo utilizado estima que un incremento de 50 ppb en el promedio horario de ozono de un día ocasionaría, al día siguiente, un incremento del 9.9% en las consultas de urgencias por infecciones respiratorias altas en el periodo invernal, pudiendo incrementarse hasta en un 30% si el incremento se diera en cinco días consecutivos como promedio. Conclusiones. Los resultados sugieren que la exposición de los menores de 15 años al ozono y bióxido de nitrógeno inciden significativamente sobre el número de consultas ocasionadas por motivos respiratorios en esta zona de la Ciudad de México.

    13. Sex-Specific Consequences of Neonatal Stress on Cardio-Respiratory Inhibition Following Laryngeal Stimulation in Rat Pups

      Abstract The presence of liquid near the larynx of immature mammals triggers prolonged apneas with significant O2 desaturations and bradycardias. When excessive, this reflex (the laryngeal chemoreflex; LCR) can be fatal. Our understanding of the origins of abnormal LCR are limited; however, perinatal stress and male sex are risk factors for cardio-respiratory failure in infants. Because exposure to stress during early life has deleterious and sex-specific consequences on brain development it is plausible that respiratory reflexes are vulnerable to neuroendocrine dysfunction. To address this issue, we tested the hypothesis that neonatal maternal separation (NMS) is sufficient to exacerbate LCR-induced cardio-respiratory inhibition in anesthetized rat pups. Stressed pups were separated from their mother 3 h/d from postnatal days 3 to 12. At P14–P15, pups were instrumented to monitor breathing, O2 saturation (Spo2), and heart rate. The LCR was activated by water injections near the larynx (10 µl). LCR-induced apneas were longer in stressed pups than controls; O2 desaturations and bradycardias were more profound, especially in males. NMS increased the frequency and amplitude of spontaneous EPSCs (sEPSCs) in the dorsal motor nucleus of the vagus (DMNV) of males but not females. The positive relationship between corticosterone and testosterone observed in stressed pups (males only) suggests that disruption of neuroendocrine function by stress is key to sex-based differences in abnormal LCR. Because testosterone application onto medullary slices augments EPSC amplitude only in males, we propose that testosterone-mediated enhancement of synaptic connectivity within the DMNV contributes to the male bias in cardio-respiratory inhibition following LCR activation in stressed pups.

      Radiculomegaly affecting incisors, canines or premolars is a rare radiological finding (Maden et al., 2010) but is pathognomomic of a rare x-linked dominant syndrome called oculo-facio-cardio-dental syndrome (OFCDS). As this syndrome includes cardiac malformations and can lead to blindness due to congenital glaucoma, oral and maxillofacial surgeons should be aware of the somatic anomalies potentially associated with radiculomegaly. We report a typical case of OFCDS and provide the first description of the microscopic dental anomalies associated with this syndrome.

      Growing evidence indicates that overproduction of reactive oxygen species (ROS) plays a prominent role in the development of cardio- and cerebro-vascular diseases. Among the mechanisms identified to produce oxidative stress in the vascular wall, those mediated by membrane-bound NAD(P)H oxidases represent a major one. NAD(P)H oxidases are a family of enzymes that generate ROS both in phagocytic and non-phagocytic cell types. Vascular NAD(P)H oxidase contains the membrane-bound subunits Nox1, Nox2 (gp91phox), Nox4 and p22phox, the catalytic site of the oxidase, and the cytosolic components p47phox and p67phox. Rac1 (Ras-related C3 botulinum toxin substrate1) is a small GTPase essential for the assembly and activation of NADPH oxidase. Several molecular and cellular studies have reported the involvement of Rac1 in different cardiovascular pathologies, such as vascular smooth muscle proliferation, cardiomyocyte hypertrophy, endothelial cell shape change, atherosclerosis and endothelial dysfunction in hypertension. In addition, increased activation of NADPH oxidase by Rac1 has been reported in animals and humans after myocardial infarction and heart failure. The Rac1/NADPH pathway has also been found involved in different pathologies of the cerebral district, such as ischemic stroke, cognitive impairment, subaracnoid hemorrhage and neuronal oxidative damage typical of several neurodegenerative disorders. In addition, thrombotic events are an important step in the onset of cardio- and cerebrovascular diseases. Rac1 has been found involved also in platelet activation, inducing actin polymerization and lamellipodia formation, which are necessary steps for platelet aggregation. Taken together, the evidence candidates Rac1 as a new pharmacological target of cardiovascular and cerebrovascular diseases. Although the involvement of Rac1 in the beneficial pleiotropic effects of drugs such as statins is well known, and the onset of numerous side effects has raised concern for the

      Apelin-13 was recently proposed as an alternative to the recommended β-adrenergic drugs for supporting endotoxin-induced myocardial dysfunction. Since Apelin-13 signals through its receptor (Apelin peptide jejunum) to exert singular inotropic/vasotropic actions and to optimize body fluid balance, this candidate pathway might benefit septic shock management. Whether the newly discovered ELABELA (ELA), a second endogenous ligand of the Apelin peptide jejunum receptor highly expressed in the kidney, further improves cardio-renal impairment remains unknown. Interventional study in a rat model of septic shock (128 adult males) to assess the effects of ELA and Apelin-13 on vascular and cardio-renal function. Experiments were performed in a tertiary care University-based research institute. Polymicrobial sepsis-induced cardiac dysfunction was produced by cecal ligation puncture to assess hemodynamic efficacy, cardioprotection, and biomechanics under acute or continuous infusions of the apelinergic agonists ELA or Apelin-13 (39 and 15 µg/kg/hr, respectively) versus normal saline. Apelinergic agonists improved 72-hour survival after sepsis induction, with ELA providing the best clinical outcome after 24 hours. Apelinergic agonist infusion counteracted cecal ligation puncture-induced myocardial dysfunction by improving left ventricular pressure-volume relationship. ELA-treated cecal ligation puncture rats were the only group to 1) display a significant improvement in left ventricular filling as shown by increased E-wave velocity and left ventricular end-diastolic volume, 2) exhibit a higher plasma volume, and 3) limit kidney injury and free-water clearance. These beneficial renal effects were superior to Apelin-13, likely because full-length ELA enabled a distinctive regulation of pituitary vasopressin release. Activation of the apelinergic system by exogenous ELA or Apelin-13 infusion improves cardiovascular function and survival after cecal ligation puncture

      Whole-body cryotherapy (WBC) is the exposure of minimally dressed participants to very cold air, either in a specially designed chamber (cryo-chamber) or cabin (cryo-cabin), for a short period of time. Practitioners are vague when it comes to recommendations on the duration of a single session. Recommended exposure for cryo-chamber is 150s, but no empirically based recommendations are available for a cryo-cabin. Therefore the aim of this study was to examine thermal and cardio-vascular responses after 90, 120, 150 and 180s of WBC in a cryo-cabin. Our hypothesis was that skin temperature would be significantly lower after longer exposers. Twelve male participants (age 23.9±4.2 years) completed four WBC of different durations (90, 120, 150 and 180s) in a cryo-cabin. Thermal response, heart rate and blood pressure were measured prior, immediately after, 5min after and 30min after the session. Skin temperature differed significantly among different durations, except between 150 and 180s. There was no significant difference in heart rate and blood pressure. Thermal discomfort during a single session displayed a linear increase throughout the whole session. Our results indicate that practitioners and clinicians using cryo-cabin for WBC do not need to perform sessions longer than 150s. We have shown that longer sessions do not substantially affect thermal and cardio-vascular response, but do increase thermal discomfort. Copyright © 2014 Elsevier Ltd. All rights reserved.

      This study was conducted to examine the effects of simulation-based education regarding care in a cardio-pulmonary emergency care as related to knowledge, clinical performance ability, and problem solving process in new nurses. An equivalent control group pre-post test experimental design was used. Fifty new nurses were recruited, 26 nurses for the experimental group and 24 nurses for the control group. The simulation-based cardio-pulmonary emergency care education included lecture, skill training, team-based practice, and debriefing, and it was implemented with the experimental group for a week in May, 2009. Data were analyzed using frequency, ratio, chi-square, Fisher's exact probability and t-test with the SPSS program. The experimental group who had the simulation-based education showed significantly higher know-ledge (t=5.76, pproblem solving process was not included (t=1.11, p=.138). The results indicate that a simulation-based education is an effective teaching method to improve knowledge and clinical performance ability in new nurses learning cardio-pulmonary emergency care. Further study is needed to identify the effect of a simulation-based team discussion on cognitive outcome of clinical nurses such as problem solving skills.

      We investigated whether residential environment characteristics related to food (unhealthful/healthful food sources ratio), walkability and public open spaces (POS; number, median size, greenness and type) were associated with incidence of four cardio-metabolic risk factors (pre-diabetes/diabetes, hypertension, dyslipidaemia, abdominal obesity) in a biomedical cohort (n=3205). Results revealed that the risk of developing pre-diabetes/diabetes was lower for participants in areas with larger POS and greater walkability. Incident abdominal obesity was positively associated with the unhealthful food environment index. No associations were found with hypertension or dyslipidaemia. Results provide new evidence for specific, prospective associations between the built environment and cardio-metabolic risk factors. Copyright © 2014 Elsevier Ltd. All rights reserved.

      The concept of risk estimation of Coronary Heart Disease (CHD) is helpful for clinician to identifying high risk populations for their effective treatment. Latest studies recommended only initiating cardio-protective treatment in diabetic patients based on personalized CHD risk estimates so as to reduce undue harm from overly aggressive risk factor modification. The United Kingdom Prospective Diabetes Study (UK PDS) Risk Engine is a widely used tool to assess the risk of Cardio Vascular diseases (CVD) in diabetics. The literature search so far did not reveal any study of risk assessment among Pakistani Diabetics. Methods: This descriptive study is based on the data of 470 type-2 diabetics seen in Department of Endocrinology and Metabolism, Services Institute of Medical Sciences, Lahore during 2011. The data of these 470 patients was analyzed through UKPDS Risk Engine. CHD risk was calculated. Results: The 10 years risk of CHD, fatal CHD, stroke and fatal stroke was 9.4%, 4.4%, 1.7% and 0.2% respectively. Conclusions: The present study show a lower risk of CVD occurring among Pakistani diabetics as compared to studies from western countries. (author)

      Takeaway food consumption is positively associated with adiposity. Little is known about the associations with other cardio-metabolic risk factors. This study aimed to determine whether takeaway food consumption is associated with fasting glucose, insulin, lipids, homeostasis model assessment (HOMA) and blood pressure. A national sample of 1896, 26-36 year olds completed a questionnaire on socio-demographics, takeaway food consumption, physical activity and sedentary behaviour. Waist circumference and blood pressure were measured, and a fasting blood sample was taken. For this analysis, takeaway food consumption was dichotomised to once a week or less and twice a week or more. Linear regression was used to calculate differences in the adjusted mean values for fasting lipids, glucose, insulin, HOMA and blood pressure. Models were adjusted for age, employment status, leisure time physical activity and TV viewing. Compared with women who ate takeaway once a week or less, women who ate takeaway twice a week or more had significantly higher adjusted mean fasting glucose (4.82 vs 4.88 mmol/l, respectively; P=0.045), higher HOMA scores (1.27 vs 1.40, respectively, P=0.034) and tended to have a higher mean fasting insulin (5.95 vs 6.45 mU/l, respectively, P=0.054). Similar associations were observed for men for fasting insulin and HOMA score, but the differences were not statistically significant. For both women and men adjustment for waist circumference attenuated the associations. Consuming takeaway food at least twice a week was associated with cardio-metabolic risk factors in women but less so in men. The effect of takeaway food consumption was attenuated when adjusted for obesity.

      During aging, sensorimotor, cognitive and physical performance decline, but can improve by training and exercise indicating that age-related changes are treatable. Dancing is increasingly used as an intervention because it combines many diverse features making it a promising neuroplasticity-inducing tool. We here investigated the effects of a 6-month dance class (1 h/week) on a group of healthy elderly individuals compared to a matched control group (CG). We performed a broad assessment covering cognition, intelligence, attention, reaction time, motor, tactile, and postural performance, as well as subjective well-being and cardio-respiratory performance. After 6 months, in the CG no changes, or further degradation of performance was found. In the dance group, beneficial effects were found for dance-related parameters such as posture and reaction times, but also for cognitive, tactile, motor performance, and subjective well-being. These effects developed without alterations in the cardio-respiratory performance. Correlation of baseline performance with the improvement following intervention revealed that those individuals, who benefitted most from the intervention, were those who showed the lowest performance prior to the intervention. Our findings corroborate previous observations that dancing evokes widespread positive effects. The pre-post design used in the present study implies that the efficacy of dance is most likely not based on a selection bias of particularly gifted individuals. The lack of changes of cardio-respiratory fitness indicates that even moderate levels of physical activity can in combination with rich sensorimotor, cognitive, social, and emotional challenges act to ameliorate a wide spectrum of age-related decline.

      Objective: To evaluate the efficiency and preliminary results of transcatheter closure of secundum atrial septal defect (ASD) with CardioSEAL septal occluder. Methods: There were 12 patients in this study. Trans-esophageal echocardiography (TEE) before the interventions confirmed the ASDs with a mean diameter of *13.14 +- 3.48) mm (ranging from 8 to 20 mm). There were 11 isolated ASDs and 1 multi-defects ASD in the group. Each ASD was occluded with CardioSEAL septal occluder through the percutaneous procedure. The closure procedure was guided by fluoroscopy and trans-esophageal echocardiography. The TEE was done immediately after the procedure to find whether there was residual shunt. Trans-thoracic-echocardiography (TTE), ECG, and X-ray examination were done 24 hours, 1 month, 3 months, and 1 year after the procedures as follow-up to evaluate the efficiency. Results: The placements of the occluders were successful in 11 cases. There were no mortality and no emergent surgery during the procedures. TEE confirmed that there were trivial and small residual shunts in 3 cases immediately after the procedures. TTE confirmed small residual shunts in 2 cases 24 hour after the procedures, and in 1 case 1 month, 3 month, and 1 year after the procedures. Conclusion: Transcatheter closure of secundum ASD with CardioSEAL septal occluder was an efficient nonsurgical method. It could be the method of choice in treating the ASDs with special anatomic variations. It had a high successful rate of device placement and satisfied preliminary results, but the long-term follow-up was needed

Ramadan is the ninth and holiest month(Hijra of the 12-month Islamic calendar during which Muslims fast from dawn to dusk each day maintaining certain rules (consuming food/drink once, avoiding smoking and sexual activity, as well as impure thoughts, words and immoral behavior. It is observed by Muslims as a month of fasting to commemorate the first revelation of the Qur'an to Muhammad. Aims & Objectives: To evaluate the effect of Ramadan on cardio-metabolic profile among adult Muslims residing in rural West Bengal. Methods and Materials: The present study was a longitudinal community based study done among 43 Muslims residing in a village of West Bengal during 6thJune to 7th July 2016. Cardio-metabolic profile (physical activity, diet, BMI, blood pressure, blood lipids and glucose were assessed before, during and after Ramadan. Results: There was a significant reduction in VLDL and TG level while significant elevation in HDL level along with the reduction in Framingham risk score after fasting. All the anthropometric measurements along with blood pressure reduced significantly after Ramadan with significant reduction in intake of all micro-nutrients during Ramadan. However physical activity also reduced significantly during Ramadan. Conclusion: Our study had found no detrimental effects of Ramadan fasting on the contrary has an overall beneficial effect on cardiovascular profile was observed.

      Information on cardiovascular gene transcription is fragmented and far behind the present requirements of the systems biology field. To create a comprehensive source of data for cardiovascular gene regulation and to facilitate a deeper understanding of genomic data, the CardioTF database was constructed. The purpose of this database is to collate information on cardiovascular transcription factors (TFs), position weight matrices (PWMs), and enhancer sequences discovered using the ChIP-seq method. The Naïve-Bayes algorithm was used to classify literature and identify all PubMed abstracts on cardiovascular development. The natural language learning tool GNAT was then used to identify corresponding gene names embedded within these abstracts. Local Perl scripts were used to integrate and dump data from public databases into the MariaDB management system (MySQL). In-house R scripts were written to analyze and visualize the results. Known cardiovascular TFs from humans and human homologs from fly, Ciona, zebrafish, frog, chicken, and mouse were identified and deposited in the database. PWMs from Jaspar, hPDI, and UniPROBE databases were deposited in the database and can be retrieved using their corresponding TF names. Gene enhancer regions from various sources of ChIP-seq data were deposited into the database and were able to be visualized by graphical output. Besides biocuration, mouse homologs of the 81 core cardiac TFs were selected using a Naïve-Bayes approach and then by intersecting four independent data sources: RNA profiling, expert annotation, PubMed abstracts and phenotype. The CardioTF database can be used as a portal to construct transcriptional network of cardiac development. Database URL: http://www.cardiosignal.org/database/cardiotf.html.

      Full Text Available La hidroxiapatita sintética (HA es un fosfato de calcio con una composición química muy similar a la del hueso humano, lo cual la hace biocompatible con los tejidos vivos. La biocompatibilidad posibilita su uso en variadas aplicaciones médicas. En esta investigación se realizó un seguimiento a las propiedades cristaloquímicas de muestras de HA sintética tratadas a diferentes temperaturas, las que se sometieron a solución fisiológica de Ringer durante periodos de 5 y de 30 días. La medición de la conductividad y el análisis de las muestras, por medio de espectrofotometría UV-VIS, análisis por ion selectivo, DRX, FTIR y SEM, permitieron mostrar la gran dependencia de la cristalinidad con el tratamiento térmico. La muestra más cristalina se obtuvo a una temperatura de 1050 °C. La mayor solubilidad se presentó en las muestras más cristalinas; además, se evidenció la presencia de dos mecanismos que compiten cuando las muestras se someten a solución Ringer: la disolución y la precipitación.

      Full Text Available Background: Islam is the second largest religion of the World (23% and Muslims are the second largest majority of Indian Republic (14.3%. Ramadan is the ninth and holiest month(Hijra of the 12-month Islamic calendar during which Muslims fast from dawn to dusk each day maintaining certain rules (consuming food/drink once, avoiding smoking and sexual activity, as well as impure thoughts, words and immoral behavior. It is observed by Muslims as a month of fasting to commemorate the first revelation of the Qur'an to Muhammad. Aims & Objectives: To evaluate the effect of Ramadan on cardio-metabolic profile among adult Muslims residing in rural West Bengal. Methods and Materials: The present study was a longitudinal community based study done among 43 Muslims residing in a village of West Bengal during 6thJune to 7th July 2016. Cardio-metabolic profile (physical activity, diet, BMI, blood pressure, blood lipids and glucose were assessed before, during and after Ramadan. Results: There was a significant reduction in VLDL and TG level while significant elevation in HDL level along with the reduction in Framingham risk score after fasting. All the anthropometric measurements along with blood pressure reduced significantly after Ramadan with significant reduction in intake of all micro-nutrients during Ramadan. However physical activity also reduced significantly during Ramadan. Conclusion: Our study had found no detrimental effects of Ramadan fasting on the contrary has an overall beneficial effect on cardiovascular profile was observed.

      Full Text Available Abstract Background During the last 35 years the poor ranking of Hungary on the list of life expectancy at birth among European countries, has not changed. In 1970 our lag behind the leading European countries was the smallest. The gap was growing between 1970 and 1993 but from 1994 onwards the life expectancy at birth in Hungary has increased continuously and somewhat faster than in other European countries. The aim of this study was to analyze the association between decreasing cardiovascular mortality rates, as a main cause of death and the increase in cardio-metabolic prescriptions and possible changes in lifestyle behavior. Methods Analyses were conducted on national data concerning cardiovascular mortality and the number of cardio-metabolic drug prescription per capita. The association between yearly rates of cardiovascular events and changes in antihypertensive, antilipidemic and antidiabetic prescription rates was analyzed. The changes in other cardiovascular risk factors, like lifestyle were also considered. Results We observed a remarkable decline of mortality due to stroke and acute myocardial infarction (AMI. The fall was significantly associated with all prescription rates. The proportion of each treatment type responsible for suppression of specific mortality rates is different. All treatment types comparably improved stroke mortality, while antilipidemic therapy improved AMI outcome. Conclusions These results emphasize the importance of a comprehensive strategy that maximizes the population coverage of effective treatments. Hungary appears to be at the beginning of the fourth stage of epidemiologic transition, i.e. it has entered the stage of delayed chronic noninfectious diseases.

      Background Accumulating evidence demonstrates that both maternal pre-pregnancy body mass index (mppBMI) and gestational weight gain (GWG) are associated with adult offspring adiposity. However, whether these maternal attributes are related to other cardio-metabolic risk factors in adulthood has not been comprehensively studied. Methods and Results We used a birth cohort of 1400 young adults born in Jerusalem, with extensive archival data as well as clinical information at age 32, to prospectively examine the associations of mppBMI and GWG with adiposity and related cardio-metabolic outcomes. Greater mppBMI, independent of GWG and confounders, was significantly associated with higher offspring BMI, waist circumference (WC), systolic and diastolic BP, insulin and triglycerides and with lower HDL-C. For example, the effect sizes were translated to nearly 5kg/m2 higher mean BMI, 8.4cm higher WC, 0.13mmol/L (11.4mg/dL) higher triglycerides and 0.10mmol/L (3.8mg/dL) lower HDL-C among offspring of mothers within the upper mppBMI quartile (BMI>26.4kg/m2) compared to the lower (BMI14kg) and lower (GWG<9kg) quartiles of GWG were compared. Further adjustment for offspring adiposity attenuated to null the observed associations. Conclusions Maternal size both before and during pregnancy are associated with cardio-metabolic risk factors in young adult offspring. The associations appear to be driven mainly by offspring adiposity. Future studies that explore mechanisms underlying the intergenerational cycle of obesity are warranted to identify potentially novel targets for cardio-metabolic risk-reduction interventions.

      Psychiatric disorders have been reported in over 10% of patients with velo-cardio-facial syndrome (VCFS) in long-term follow-up. To further explore the behavioral and psychiatric findings associated with VCFS in adulthood, detailed clinical histories of two patients - one with VCFS who developed a psychotic illness, and one with schizophrenia who was found to have dysmorphological features associated with VCFS - are described in the current report. The observed overlap of physical and psychiatric symptoms in these two patients suggests that VCFS and psychotic disorders may share a pathogenetic mechanism. This could be consistent with a contiguous gene model for VCFS and psychosis, suggesting chromosome 22q11 as a possible candidate region for genetic studies of schizophrenia. 26 refs., 2 tabs.

      Full Text Available Background: Physical or cardio-respiratory fitness are of the best important physiological variables in children with cerebral palsy (CP, but the researches on exercise response of individuals with CP are limited. Our aim was to determine the effect of sub-maximal rehabilitation program (aerobic exercise on maximal oxygen uptake, oxygen pulse and cardio- respiratory physiological variables of children with moderate to severe spastic cerebral palsy diplegia and compare with able-bodied children. Methods: In a controlled clinical trial study, 15 children with diplegia spastic cerebral palsy, were recruited on a voluntarily basis (experimental group and 18 subjects without neurological impairments selected as control group. In CP group, aerobic exercise program performed on the average of exercise intensity (144 beat per minute of heart rate, 3 times a week for 3 months. The time of each exercise session was 20-25 minutes. Dependent variables were measured in before (pretest and after (post test of rehabilitation program through Mac Master Protocol on Tantories cycle ergometer in CP group and compared with the control group. Results: The oxygen pulse (VO2/HR during ergometery protocol was significantly lower in CP group than normal group (P<0.05. No significant statistical difference in maximal oxygen uptake (VO2 max was found between groups. The rehabilitation program leads to little increase of this variable in CP group. After sub-maximal exercise in pretest and post test, the heart rate of patient group was greater than control group, and aerobic exercise leads to significant decrease in heart rate in CP patients(P<0.05. Conclusion: The patients with spastic cerebral palsy, because of high muscle tone, severe spasticity and involuntarily movements have higher energy cost and lower aerobic fitness than normal people. The rehabilitation exercise program can improve physiological function of muscle and cardio-respiratory endurance in these

      The usefulness of computed tomography (CT) in categorizing lesions of the cardio phrenic angles is showed. Twenty five patients with abnormalities in these sites were studied by CT. These abnormalities included ten cases of lymphomatous adenopathy, two cases of metastatic adenopathy, four cases of pericardial cyst, four cases of loculated pleural effusion, and five cases of prominent epicardial fat. A correct evaluation of all cases was possible by utilizing the CT densities numbers and the topographic characteristics of the lesions. CT showed high sensitivity in detecting paracardiac adenopathy which may affect the staging and treatment of neoplasia. (author)

Para ello se han cultivado cuantitativamente las muestras del lavado broncoalveolar broncoscópico, procedimiento que no siempre es posible. Objetivo. Evaluar la concordancia microbiológica entre muestras respiratorias tomadas por lavado broncoalveolar broncoscópico y no broncoscópico, y establecer si el uso previo de antibióticos y el momento de presentación de la neumonía pueden afectarla. Materiales y métodos. Estudio prospectivo realizado en el Hospital Universitario San Vicente de Paúl, en 38 pacientes con sospecha de neumonía y con asistencia respiratoria mecánica. En todos se practicó el lavado broncoalveolar por fibrobroncoscopia y el lavado no broncoscópico usando un catéter telescopado de punta preformada (Balcath®. Todas las muestras fueron procesadas siguiendo protocolos microbiológicos convencionales. Resultados. Considerando el lavado broncoalveolar por fibrobroncoscopia como patrón de referencia, los cultivos permitieron identificar el agente en 60,5% de los casos. El acuerdo diagnóstico se logró en 82% de los pacientes y 79% de los aislamientos. Utilizando el índice kappa de Cohen, la concordancia general entre los dos métodos fue 0,76 [0,60-0,93]; pero en quienes habían recibido antibióticos previos fue 0,26 [0,05-0,48], versus 1,0 en quienes no lo habían hecho (p<0,0001. La concordancia no difirió significativamente cuando se compararon los casos de neumonía temprana y tardía. Conclusiones. La concordancia general entre los dos métodos de lavado broncoalveolar es buena en pacientes con neumonía y respiración asistida mecánicamente. Sin embargo, el uso previo de antibióticos y no el momento de aparición de la neumonía, disminuye ésta significativamente.

      Through the success of basic and disease-specific research, cancer survivors are one of the largest growing subsets of individuals accessing the healthcare system. Interestingly, cardiovascular disease is the second leading cause of morbidity and mortality in cancer survivors after recurrent malignancy. This recognition has helped stimulate a collaboration between oncology and cardiology practitioners and researchers, and the portmanteau cardio-oncology (also known as onco-cardiology) can now be found in many medical centers. This collaboration promises new insights into how cancer therapies impact cardiovascular homeostasis and long-term effects on cancer survivors. In this review, we will discuss the most recent views on the cardiotoxicity related to various classes of chemotherapy agents and radiation. We will also discuss broadly the current strategies for treating and preventing cardiovascular effects of cancer therapy. © 2016 American Heart Association, Inc.

      2017-09-01

      Normobaric hypoxic conditioning (HC) is defined as exposure to systemic and/or local hypoxia at rest (passive) or combined with exercise training (active). HC has been previously used by healthy and athletic populations to enhance their physical capacity and improve performance in the lead up to competition. Recently, HC has also been applied acutely (single exposure) and chronically (repeated exposure over several weeks) to overweight and obese populations with the intention of managing and potentially increasing cardio-metabolic health and weight loss. At present, it is unclear what the cardio-metabolic health and weight loss responses of obese populations are in response to passive and active HC. Exploration of potential benefits of exposure to both passive and active HC may provide pivotal findings for improving health and well being in these individuals. A systematic literature search for articles published between 2000 and 2017 was carried out. Studies investigating the effects of normobaric HC as a novel therapeutic approach to elicit improvements in the cardio-metabolic health and weight loss of obese populations were included. Studies investigated passive ( n = 7; 5 animals, 2 humans), active ( n = 4; all humans) and a combination of passive and active ( n = 4; 3 animals, 1 human) HC to an inspired oxygen fraction ([Formula: see text]) between 4.8 and 15.0%, ranging between a single session and daily sessions per week, lasting from 5 days up to 8 mo. Passive HC led to reduced insulin concentrations (-37 to -22%) in obese animals and increased energy expenditure (+12 to +16%) in obese humans, whereas active HC lead to reductions in body weight (-4 to -2%) in obese animals and humans, and blood pressure (-8 to -3%) in obese humans compared with a matched workload in normoxic conditions. Inconclusive findings, however, exist in determining the impact of acute and chronic HC on markers such as triglycerides, cholesterol levels, and fitness capacity

      To illuminate the synchronization phenomena between heartbeat and music, the effects of a sedative music of variable tempo on heart rates were investigated. In the experiment, nine subjects were exposed to the sedative music with having changes in its tempo. The tempo gradually increases, decreases, or stands stable in the music (hereafter these experimental condition are named as Up, Down, and Flat condition). With regard to the analysis of synchronization, we introduced our formerly developed Cardio-Music Synchrogram, which was used to extract statistically significant synchronization period between heartbeat and music. As a result, it was suggested that the sedative music in Down condition induced synchronization more frequently than Flat and Up conditions.

      Full Text Available Cigarette smoking causes cardiovascular disease and is associated with poor kidney function in individuals with diabetes mellitus and primary kidney diseases. However, the association of smoking on patients with atherosclerotic renal artery stenosis has not been studied. The current study utilized data from the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL, NCT00081731 clinical trial to evaluate the effects of smoking on the risk of cardio-renal events and kidney function in this population. Baseline data showed that smokers (n = 277 out of 931 were significantly younger at enrollment than non-smokers (63.3±9.1 years vs 72.4±7.8 years; p<0.001. In addition, patients who smoke were also more likely to have bilateral renal artery stenoses and peripheral vascular disease (PVD. Longitudinal analysis showed that smokers experienced composite endpoint events (defined as first occurrence of: stroke; cardiovascular or renal death; myocardial infarction; hospitalization for congestive heart failure; permanent renal replacement; and progressive renal insufficiency defined as 30% reduction of GFR from baseline sustained for ≥ 60 days at a substantially younger age compared to non-smokers (67.1±9.0 versus 76.1±7.9, p<0.001. Using linear regression and generalized linear modeling analysis controlled by age, sex, and ethnicity, smokers had significantly higher cystatin C levels (1.3±0.7 vs 1.2±0.9, p<0.01 whereas creatinine and estimated glomerular filtration rate (eGFR were not different from non-smokers. From these data we conclude that smoking has a significant association with deleterious cardio-renal outcomes in patients with renovascular hypertension.

      Both aging and obesity are related to dysregulated immune function, which may be responsible for increased risk of infection and also chronic non-infectious diseases. Dietary lipids have been shown to impact immune and inflammatory responses and cardio-metabolic risk factors. No information on the impact of olive oil on immune responses of overweight and obese older adults is available. We aimed to determine the effect of replacing oils used in a typical American diet with extra virgin olive oil for 3 months on immune responses and cardio-metabolic risk factors in overweight and obese older adults. This was a randomized, single-blinded and placebo-controlled trial in 41 overweight or obese participants (aged ≥ 65) who consumed a typical American diet. Participants in the control (CON, n = 21) group were provided with a mixture of corn, soybean oil and butter, and those in the olive oil (OO, n = 20) group, with extra virgin olive oil, to replace substitutable oils in their diet. At baseline and 3 months, we measured blood pressure, biochemical and immunological parameters using fasting blood, and delayed-type hypersensitivity (DTH) skin response. Compared to the CON group, the OO group showed decreased systolic blood pressure (P groups. Our results indicate that substitution of oils used in a typical American diet with extra virgin olive oil in overweight and obese older adults may have cardio-metabolic and immunological health benefits. This trial was registered at clinicaltrials.gov as NCT01903304.

      Tissue engineers have been seeking the 'Holy Grail' solution to calcification and cytotoxicity of implanted tissue for decades. Tissues with all of the desired qualities for surgical repair of congenital heart disease (CHD) are lacking. An anti-calcification tissue engineering process (ADAPT TEP) has been developed and applied to bovine pericardium (BP) tissue (CardioCel, AdmedusRegen Pty Ltd, Perth, WA, Australia) to eliminate cytotoxicity, improve resistance to acute and chronic inflammation, reduce calcification and facilitate controlled tissue remodeling. Clinical data in pediatric patients, and additional pre-market authorized prescriber data demonstrate that CardioCel performs extremely well in the short term and is safe and effective for a range of congenital heart deformations. These data are supported by animal studies which have shown no more than normal physiologic levels of calcification, with good durability, biocompatibility and controlled healing.

      Full Text Available BACKGROUND: The study aimed to perform an audit of intensive care unit admissions in the paediatric cardio-thoracic population in Enugu, Nigeria and examine the challenges and outcome in this high risk group. Ways of improvement based on this study are suggested. METHODS: The hospital records of consecutive postoperative pediatric cardiothoracic admissions to the multidisciplinary and cardiothoracic intensive care units of the University of Nigeria Teaching Hospital (UNTH Enugu, Nigeria to determine their Intensive Care Unit management and outcome over a 2 year span - June 2002 to June 2004 were retrospectively reviewed. Data collected included patient demographics, diagnosis, duration of stay in the intensive care unit, therapeutic interventions and outcome. RESULTS: There were a total of thirty consecutive postoperative paediatric admissions to the intensive care unit over the 2 year study period. The average age of the patients was 5.1 years with a range of 2 weeks to 13 years. Twelve patients had cardiac surgery with cardiopulmonary bypass (CPB, three patients had colon transplant, four patients had pericardiotomy/pericardicectomy, and five patients had diagnostic/therapeutic bronchoscopy. The remaining patients had the following surgeries, thoracotomy for repair of diaphragmatic hernia/decortications, delayed primary repair of esophageal atresia and gastrostomy. Two patients had excision of a cervical teratoma and cystic hygroma. The average duration of stay in the intensive care unit was 6.2 days. Ten patients (33% received pressor agents for organ support. Five patients (17% had mechanical ventilation, while twenty-five patients (83% received oxygen therapy via intranasal cannula or endotracheal tube. Seven patients (23% received blood transfusion in the ICU. There was a 66% survival rate with ten deaths. CONCLUSION: Paediatric cardio-thoracic services in Nigeria suffer from the problems of inadequate funding and manpower flight to better

      2015-01-01

      This book is designed for clinical cardiologists and other physicians working with cardiac patients, where specific specialized teams of cardio-oncologists are not available and who are called to perform a clinical consultation to evaluate both the cardiac condition and the eligibility for chemotherapy or radiotherapy treatment, and to evaluate if a cancer treatment produces toxic effects on a patient treated with chemo or radiotherapy and if appearance of new symptoms is due to this treatment. In recent years, progress in oncologic therapy has resulted in important developments and the prognostic improvement of patients with malignancy. The cornerstone of chemotherapy are the anthracyclines (and the analogue Mitoxantrone), that are direct cellular toxic agents and that are among the most powerful anti-neoplastic drugs, but their cardiac toxicity is well known. Significant breakthroughs in cancer therapy have also been achieved with the introduction of signalling inhibitors, such as VEGF inhibitors, HERB2 inh...

      Cardiovascular disease (CVD) is an emerging threat to the health of populations in Africa. With the inadequate health infrastructures, understaffed and underfunded health systems, African countries are ill-prepared to cope with the increasing demand for care for CVD, particularly for populations in remote and underserved rural areas, where 60% of the population currently reside. Task shifting and telehealth have been suggested as strategies to overcome the current health workforce shortage in African countries, and to increase access to prevention and curative services for emerging CVD. However, strategies for promoting their incorporation into the existing health systems, have yet to be developed. The Cardio Pad(®) initiative (originating from Cameroon) seeks to provide appropriate solutions to improve the application of telemedicine for CVD prevention and control in remote African settings. The Cardio Pad(®) is a tele-cardiology device which provides a number of advantages in terms of cost, ease of use, autonomy and reduced technology requirements. It is a fully touch screen medical device which enables cardiac tests such as electrocardiograms (ECG) to be performed in remote underserved areas (rural areas for instance), while the test results are transferred wirelessly via mobile phone connection, to specialist physicians who can interpret them and provide assistance with case management. While most of the current telemedicine clinical services on the African continent receive most expertise from developed countries, the Cardio Pad(®), a local invention by a 26-year-old Cameroon-trained engineer demonstrates how much innovative solutions to combat CVD and other health issues could and should be developed locally in Africa.

      Full Text Available La aparición de los fenómenos severos en el tiempo meteorológico (tornados, granizos y vientos lineales con rachas destructoras está relacionada con cambios importantes en la morfología de las tormentas eléctricas. Las tormentas que alcancen ese estadio son consideradas como un tipo especial de tormentas eléctricas llamadas tormentas eléctricas locales severas (TELS. El desarrollo de las TELS en la Zona Metropolitana de Guadalajara (ZMG es una realidad y se debe considerar en la protección de la sociedad, debido a las pérdidas de vidas, daños materiales y cuantiosas afectaciones que ocurren como consecuencia de éstas. Al no contar con una cronología de las TELS en la ZMG fue necesaria la compilación de las mismas como base para realizar su climatología. Entre los resultados obtenidos se destaca que las TELS ocurren desde mayo hasta noviembre, en particular, en los meses de junio, julio y agosto. La mayoría se presenta durante horas de la tarde o de la noche, pero un grupo nada despreciable también ocurre durante la madrugada. Queda establecido que las TELS constituyen un elemento importante del clima de la ZMG que no puede ser ignorado desde el punto de vista científico y mucho menos en la práctica, por los efectos que produce en muchas ocasiones.

      In this study neutron activation analysis was applied to analyze lichen samples used as atmospheric pollutant biomonitors in order to verify if there is correlation between air pollution and its effects on the cardio respiratory system. Canoparmelia texana lichenized fungii species was chosen for passive biomonitoring of atmospheric pollutants. The population group selected for this study was adults over 45 years. Lichen samples collected in Sao Paulo city were cleaned, freeze-dried and ground for the analyses. Aliquots of samples were irradiated at the IEA-R1 nuclear research reactor for short and long periods along with synthetic element standards. The induced gamma activities of the samples and standards were measured using a gamma ray spectrometer with an HPGe detector and the concentrations of As, Ba, Br, Ca, Cd, Cl, Co, Cr, Cs, Fe, Hf, K, Mg, Mn, Na, Rb, Sb, Sc, Se,Th, V, Zn and lanthanides were determined. For quality control of the results, certified reference materials were analyzed together. Mortality data for the population due to cardio-respiratory diseases were obtained from the database of the Secretariat of Health of the Sao Paulo Municipality for the years 2005-2009. Results obtained point to vehicular and industrial emissions as the origins of pollutants in Sao Paulo city. The statistical treatment of Pearson's correlation applied to the results of lichen element concentrations and mortality rates indicated significant positive correlation for the elements Co, Mn and Zn for adults.

Así mismo, identificar tópicos afines a las RAM por dicha vacuna. Diseño: Estudio prospectivo y descriptivo basado en la notificación espontánea. Institución: Local central del Instituto Nacional de Salud en Lima. Participantes: Trabajadores de salud. Metodología: Las RAM notificadas espontáneamente fueron registradas en Hojas RAM. Se aplicó un algoritmo para buscar una relación causa-efecto. Principales medidas de resultados: Reacciones adversas a la vacuna influenza A(H1N1. Resultados: Hubo tres notificaciones espontáneas entre 148 trabajadores de salud vacunados (2% contra la influenza A(H1N1 2009. La relación causa-efecto fue ‘cierta’ para fiebre y fatiga y ‘posible’ para afecciones respiratorias en tres mujeres (faringitis aguda, catarro nasal agudo, bronquitis catarral. Conclusiones: Entre los pocos trabajadores de salud que presentaron RAM, las afecciones respiratorias con una relación considerada ‘posible’ podría interpretarse que las mujeres serían más sensibles para esa RAM comparadas con los varones. Las RAM fiebre y fatiga alcanzaron una relación considerada ‘cierta’. La menor cantidad de infectados en personas de tercera edad en el país y en otros podría explicarse por la presencia de ‘anticuerpos protectores’ en ellos.

      The cardio-renal syndromes (CRS) are the result of complex bidirectional organ cross-talk between the heart and kidney, with tremendous overlap of diseases such as coronary heart disease, heart failure (HF), and renal dysfunction in the same patient. Volume overload plays an important role in the pathophysiology of CRS. The appropriate treatment of overhydration, particularly in HF and in chronic kidney disease, has been associated with improved outcomes and blood pressure control. Clinical examination alone is often insufficient for accurate assessment of volume status because significant volume overload can exist even in the absence of peripheral or pulmonary edema on physical examination or radiography. Bioelectrical impedance techniques increasingly are being used in the management of patients with HF and those on chronic dialysis. These methods provide more objective estimates of volume status in such patients. Used in conjunction with standard clinical assessment and biomarkers such as the natriuretic peptides, bioimpedance analysis may be useful in guiding pharmacologic and ultrafiltration therapies and subsequently restoring such patients to a euvolemic or optivolemic state. In this article, we review the use of these techniques in CRS. Copyright © 2012 Elsevier Inc. All rights reserved.

Esta vía puede suponer muchas ventajas para el tratamiento de los pacientes con un alto riesgo quirúrgico y rechazados para los otros abordajes. Nuestro grupo comenzó a emplearla a finales del 2013 y se ha convertido en la vía preferida por delante de la transapical. En este artículo describimos nuestra técnica transaórtica paso a paso, sus ventajas e inconvenientes.

      Full Text Available Las infecciones respiratorias agudas (IRA figuran entre las principales causas de morbilidad y mortalidad infantiles en América Latina. En Guatemala, la neumonía es la primera causa de muerte en niños pequeños y ocasiona aproximadamente una tercera parte de las consultas ambulatorias a servicios pediátricos. Una buena proporción de estas muertes se deben a un manejo deficiente, atribuible a la falta de reconocimiento de los primeros signos de neumonía, a la presencia de barreras que impiden una búsqueda inmediata de atención, a la consulta a proveedores inapropiados o a recomendaciones terapéuticas inadecuadas. El propósito de esta breve investigación cualitativa fue estudiar las percepciones y los comportamientos de los habitantes de San Juan Comalapa, comunidad kaqchiquel en el altiplano central de Guatemala, en lo que respecta a las IRA. Se entrevistó a 32 madres en su domicilio con el fin de determinar cómo clasificaban las IRA y qué signos y síntomas las hacían buscar atención inmediata. Los resultados revelaron que las madres sabían reconocer la presencia de respiración rápida, pero no de tiraje respiratorio (dos signos importantes de neumonía. Cuando buscaban atención, solían acudir a médicos u otros proveedores en centros de salud y ocasionalmente en consultorios privados, pero la búsqueda raras veces era oportuna debido a la poca accesibilidad de los servicios y a la subestimación de la gravedad de los síntomas. Esta conducta podría modificarse por medio de una intervención educativa. Al final se hacen recomendaciones orientadas a mejorar la comunicación verbal entre los proveedores de atención de salud y las madres.

La leche materna provee una nutrición completa para cualquier bebé desde el nacimiento hasta los 6 meses de vida. MÉTODOS: se estudiaron 80 transicionales, pertenecientes al Grupo Básico de Trabajo No. 2 del Policlínico "Ana Betancourt", con el objetivo de identificar la frecuencia y variedad de las infecciones respiratorias agudas en relación con el tipo de lactancia recibida. Para la recolección de los datos se consideró la información reflejada en las consultas de puericultura realizadas, durante el primer año de vida, contempladas en las historias clínicas pediátricas (revisión documental. RESULTADOS: predominaron los niños lactados (83 %, aunque de estos, solo el 25 % se alimentó de forma exclusiva. La lactancia mixta, aunque mayoritaria (58 %, predomina por debajo del cuarto mes de vida y el 17 % de los casos fue lactado de manera artificial. Las infecciones respiratorias agudas fueron más frecuentes en niños que recibieron poco tiempo de lactancia mixta (19 %, así como en los que se alimentaron de modo artificial (14 %, con predominio en ellos de la mayor parte de las otitis medias y la totalidad de las neumonías. Solo en 3 de estos pacientes fue necesaria la hospitalización, y la evolución en todos los casos fue satisfactoria. CONCLUSIONES: predominó la variedad mixta de lactancia materna. Se comprobó una alta morbilidad por infecciones respiratorias agudas en los transicionales estudiados. Mientras más breve es el período de lactancia materna, mayor es el riesgo de infección y la severidad de estas.

      Ronco, Claudio; Ronco, Federico

      2012-03-01

      The "Cardio-Renal Syndrome" (CRS) is a disorder of the heart and kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction of the other. The general definition has been expanded to five subtypes reflecting the primacy of organ dysfunction and the time-frame of the syndrome: CRS type I: acute worsening of heart function (AHF-ACS) leading to kidney injury and/or dysfunction. CRS type II: chronic abnormalities in heart function (CHF-CHD) leading to kidney injury or dysfunction. CRS type III: acute worsening of kidney function (AKI) leading to heart injury and/or dysfunction. CRS type IV: chronic kidney disease (CKD) leading to heart injury, disease and/or dysfunction. CRS type V: systemic conditions leading to simultaneous injury and/or dysfunction of heart and kidney. Different pathophysiological mechanisms are involved in the combined dysfunction of heart and kidney in these five types of the syndrome.

We used the ATP III criteria and the IDF criteria for the diagnosis of MetS and sorted the subjects into 2 MetS groups: one group diagnosed per ATP III criteria (MetSa and one diagnosed per IDF criteria (MetSi. We then compared the clinical characteristics, metabolic parameters (homeostasis model assessment of insulin resistance, aspartate aminotransferase, alanine aminotransferase, and uric acid values and co-morbidities (prevalence of microalbuminuria, fatty liver, and cardiovascular disease between the MetSa, MetSi, and discordant MetS groups.ResultsThe prevalence of MetS in the MetSa group (73.6% was higher than in the MetSi group (62.2%. The MetS prevalence in the discordant group was 11.4%. The discordant group showed no significant differences in clinical characteristics (except waist circumference and body mass index, metabolic parameters, or prevalence of co-morbidities, as compared with subjects with MetS by both criteria.ConclusionIn this study, cardio-metabolic features of the subjects diagnosed with MetS using ATP III criteria, but not IDF criteria, are not significantly different from those of subjects diagnosed with MetS using both criteria.

    9. Dystrophin is required for the normal function of the cardio-protective K(ATP channel in cardiomyocytes.

      Directory of Open Access Journals (Sweden)

      Laura Graciotti

      Full Text Available Duchenne and Becker muscular dystrophy patients often develop a cardiomyopathy for which the pathogenesis is still unknown. We have employed the murine animal model of Duchenne muscular dystrophy (mdx, which develops a cardiomyopathy that includes some characteristics of the human disease, to study the molecular basis of this pathology. Here we show that the mdx mouse heart has defects consistent with alteration in compounds that regulate energy homeostasis including a marked decrease in creatine-phosphate (PC. In addition, the mdx heart is more susceptible to anoxia than controls. Since the cardio-protective ATP sensitive potassium channel (K(ATP complex and PC have been shown to interact we investigated whether deficits in PC levels correlate with other molecular events including K(ATP ion channel complex presence, its functionality and interaction with dystrophin. We found that this channel complex is present in the dystrophic cardiac cell membrane but its ability to sense a drop in the intracellular ATP concentration and consequently open is compromised by the absence of dystrophin. We further demonstrate that the creatine kinase muscle isoform (CKm is displaced from the plasma membrane of the mdx cardiac cells. Considering that CKm is a determinant of K(ATP channel complex function we hypothesize that dystrophin acts as a scaffolding protein organizing the K(ATP channel complex and the enzymes necessary for its correct functioning. Therefore, the lack of proper functioning of the cardio-protective K(ATP system in the mdx cardiomyocytes may be part of the mechanism contributing to development of cardiac disease in dystrophic patients.

The cardiovascular risk factors of these groups were assessed in three-year intervals using standard questionnaires, history taking, anthropometric measures, and metabolic/endocrine evaluation. Generalized estimating equation was used to analyze the data.Overall mean of insulin (3.55, CI: 0.66-6.45, HOMA-IR (0.63, CI: 0.08-1.18, and HOMA-β (45.90, CI: 0.86-90.93 were significantly higher in PCOS than in healthy women after adjustment for age, BMI, and baseline levels. However, the negative interaction (follow-up years × PCOS status of PCOS and normal women converged overtime. Comparing third follow-up with first, insulin and HOMA-IR decreased 10.6% and 5%, respectively in PCOS women; and increased 6.7% and 14.6%, respectively in controls (P<0.05. The results did not show any significant result for other cardio-metabolic variables including WC, lipid profile, FPG, 2-h PG, SBP, and DBP.While the insulin level and insulin resistance rate were higher in reproductive aged PCOS than in healthy women, the difference of these risk factors decreased overtime. Thus, the metabolic consequences of PCOS women in later life may be lower than those initially anticipated.

      Full Text Available La hipertensión pulmonar persistente del recién nacido es el resultado de un fracaso o de una mala adaptación circulatoria al momento de nacimiento; y representa una falla respiratoria aguda con un aumento sostenido de la resistencia vascular pulmonar, generando cortos circuitos extrapulmonares de derecha a izquierda, a través del conducto arterioso y foramen oval, con hipoxemia severa y acidosis secundaria. La clave del tratamiento reside en lograr una rápida mejoría de la oxigenación y dilatación de la arteria pulmonar para revertir los cortos circuitos con el uso de vasodilatadores pulmonares, de los cuales el óxido nítrico es el único agente aprobado por la FDA para su uso en neonatos con hipertensión pulmonar persistente del recién nacido, y debe ser considerado como el tratamiento de primera línea. Esta revisión se centrará en qué es el óxido nítrico y su papel como tratamiento de la hipertensión pulmonar persistente del recién nacido.

MATERIAL Y MÉTODOS: Se obtuvieron datos sobre consultas a urgencias de hospitales por afecciones de vías respiratorias altas, bajas y asma, en unidades del IMSS, de niños menores de 17 años de edad entre 1997 y 2001, y se estratificó por grupos etáreos (5 años. Se obtuvieron datos diarios sobre contaminantes aéreos (Ozono y PM10 y condiciones meteorológicas de la Red de Monitoreo en Ciudad Juárez. Para el análisis estadístico de los datos, se utilizó un Modelo Aditivo Generalizado, asumiendo una distribución de Poisson. RESULTADOS: Las concentraciones de ozono, pero no de PM10, se asociaron significativamente con las consultas a urgencias por afecciones respiratorias, principalmente en niños de 5 años o menores. En este grupo, un incremento de 20 ppb en 1 hr máxima de ozono se asociaron con un incremento de 8.3% en las consultas por afecciones de vías respiratorias superiores, con un retraso en la exposición de tres días, y un incremento de 12.7% en las consultas por infecciones de las vías respiratorias inferiores cuando se consideró un retraso de cuatro días en la exposición en el promedio móvil máximo de ocho horas. El efecto mayor para la muestra total, al igual que para el grupo de niños de 6 a 16 años, se observó en el retraso de tres días (5.1% para un aumento de 20 ppb en un máximo de una hora. Para este grupo no se observó un efecto significativo entre los niveles ambientales de ozono y el riesgo de contraer enfermedades de las vías respiratorias inferiores. CONCLUSIÓN: La amplitud del riesgo es de suma importancia, ya que puede representar un incremento en los costos de atención en el sistema de salud y la sociedad en general.

      Noonan, Cardio-facio-cutaneous, and Costello syndromes are disorders of the Ras/MAPK pathway that share many clinical features. This observational and anthropometric study was conducted to describe the key facial features of each syndrome in order to improve discrimination between the three conditions, particularly in young children where diagnosis is most challenging. Direct measurement of the head and face was used to enhance diagnostic accuracy, and identify the most unusual or specific dimensions. The Noonan syndrome cohort included 123 individuals, aged 6 months to 41 years. There were 20 children and adolescents with Cardio-facio-cutaneous syndrome, and 28 individuals with Costello syndrome, aged 1-32 years. The facial phenotypes of these syndromes, particularly Noonan syndrome, are well-described but objective data have not been published in peer-reviewed literature. In this study, subjective observations, in the main, were validated by anthropometry with one exception. In individuals with Costello syndrome, mouth width was normal, thus the impression of wide mouth is likely due to full lips or the mouth being viewed in relation to a narrow lower face. When the three conditions were compared objectively, syndrome-specific pattern profiles showed high concordance in early life. At older ages, Cardio-facio-cutaneous syndrome was distinguished by increased width of the mid/lower face, and reduced growth of maxillary and mandibular dimensions was noted in both Noonan and Costello syndromes. Despite substantial similarities in face shape in older individuals with these two conditions, bulbous nasal tip, full lips, and an apparently wide mouth in those with Costello Syndrome facilitate discrimination from Noonan syndrome. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

      Full Text Available La estenosis valvular aórtica es una entidad progresiva, que cuando es severa y produce síntomas, tiene un pronóstico sombrío que afecta de forma adversa la sobrevida. En estos casos el tratamiento de elección es la cirugía de cambio valvular, la cual, bajo determinadas circunstancias clínicas, puede ser de muy alto riesgo, y obliga así a considerar alternativas de manejo menos agresivas que permitan solucionar el problema. Se muestra el caso de un hombre de 65 años, con estenosis valvular aórtica severa, quien desarrolló edema pulmonar refractario al manejo médico, que se resolvió mediante valvuloplastia aórtica, como terapia puente a cirugía.Aortic valve stenosis is a progressive disease; when it is severe and symptomatic has a bleak prognosis that affects adversely the patient survival. In these cases, the treatment of choice is valve replacement surgery that under certain circumstances can bear a huge risk that forces the physician to consider less aggressive management alternatives to solve the problem. The case of a 65 years old male with severe aortic valve stenosis is reported. He developed pulmonary edema refractory to medical treatment that was solved by aortic valvuloplasty as bridge therapy to surgery.

En un área de salud correspondiente a una población de algo más de un millón de habitantes, con un hospital de base, 16 consultorios de atención primaria y ocho postas rurales, se desarrollaron actividades específicas de capacitación de personal, así como acciones de control en atención primaria y de hospitalización de niños con IRA grave. En los primeros 5 años de funcionamiento del programa (1990­1994 se observó entre niños menores de un año una disminución de la mortalidad anual por neumonía de 3,0 a 1,7 por 1 000, lo que ha contribuido a un descenso de la mortalidad infantil de 13,5 a 8,9 defunciones por 1 000 nacidos vivos. En 1994 los costos del programa alcanzaron los US$ 224 000. A juzgar por los resultados obtenidos, el programa de prevención y control de IRA puede haber sido un aporte valioso a la salud infantil del área.

      Full Text Available Los métodos moleculares para diagnosticar rinovirus humanos (RVH han aumentado la sensibilidad de detección. Esto ha permitido documentar la asociación entre los RVH y las infecciones respiratorias agudas (IRA altas y bajas. La infección por RVH durante la infancia se asoció con posterior desarrollo de asma. Se estudió la frecuencia de RVH en 186 niños menores de 6 años ambulatorios con IRA (alta o baja, durante 2 años consecutivos (1/6/2008 - 31/5/2010. Se correlacionó la presencia de RVH con los antecedentes y características clínico-epidemiológicas. La detección de RVH se realizó con una RT-PCR en tiempo real que amplifica parte de la región 5' no codificante del genoma. Los virus respiratorios clásicos se estudiaron por inmunofluorescencia. En el 61% de los niños se detectó etiología viral. Las frecuencias fueron: RVH 27%, virus sincicial respiratorio (VSR 16%, influenza A y B 9%, parainfluenza 8%, metapneumovirus 7% y adenovirus 0.5%. Se observaron coinfecciones duales en 8 casos, siendo RVH el más frecuente (en 4 de ellos. Los RVH circularon durante todo el período estudiado, con picos en invierno y primavera. No se observaron diferencias clínico-epidemiológicas significativas entre pacientes con o sin RVH, excepto un mayor porcentaje de niños afebriles con RVH. Los RVH fueron los virus más detectados en niños ambulatorios, principalmente en menores de 2 años, los segundos virus asociados a bronquiolitis, luego del VSR, y detectados tres veces más en los niños expuestos a tabaquismo pasivo (OR: 2,91; p = 0.012 que en el resto.

      Full Text Available La introducción de nuevas sustancias en la industria alimentaria ocasiona nuevas "sensibilizaciones" a multitud de productos como son materias primas de aditivos alimentarios y productos intermedios. Existen factores tanto individuales (atopía, tabaquismo, rinitis como industriales (niveles de exposición, poder de sensibilización de los alérgenos, "trabajo húmedo" asociados a un mayor riesgo de presentación de asma y dermatitis de contacto ocupacional (irritativa y alérgica. La importancia desde el punto de vista del número de casos notificados, hace necesario profundizar en el conocimiento y evidencia científica existente en cuanto a la epidemiologia e historia natural de la enfermedad profesional por hipersensibilidad. Con el objetivo de determinar la evidencia científica existente sobre la asociación entre las condiciones de trabajo y las enfermedades pulmonares y dermatosis en la industria alimentaria, se realizó un análisis sistemático de la producción científica identificada entre 2007-2012, en las principales bases de datos bibliográficas: PubMed, Scielo, Embase, Scopus, Lilacs, www.ilo.org/cisdocdatabase. Un total de 23 artículos cumplieron los criterios de inclusión. Los resultados permiten concluir que la prevalencia por hipersensibilidad varia en función de la actividad y del agente sensibilizante entre 7% y un 38,7% con un nivel de evidencia entre 2 ++ y 3. Dentro de las dermatosis ocupacionales, la dermatitis de contacto irritativa sigue siendo más prevalente que la dermatitis de contacto alérgica. La dermatitis de contacto proteínica es un trastorno frecuente en manipuladores de alimentos y debe considerarse una entidad clínica aparte. La atopía es un factor de riesgo para el desarrollo de clínica respiratoria y cutánea. No se identificaron en la literatura nuevos test diagnósticos.

      Full Text Available O objetivo desta pesquisa foi investigar as variáveis cardio-respiratórias (Pa, FC, VO2, VCO2 e Ve durante a Estimulação Elétrica Neuromuscular (EENM do quadríceps em portadores de lesão medular. Participaram da pesquisa dez pacientes (cinco paraplégicos e cinco tetraplégicos. O protocolo do teste consistiu em 10 minutos de repouso, 20 minutos de EENM dos quadriceps e 10 minutos de recuperação. Durante a EENM foram constatados baixos valores de VO2 e VCO2. Os paraplégicos apresentaram rápida cinética dos gases e os tetraplégicos lenta cinética dos gases. Houve o aumento da Pa sistólica e da FC. Ainda, os valores das variáveis cardio-respiratórias foram inversamente relatadas para o nível de lesão, ou seja, quanto maior o nível de lesão, menor os valores. Portanto, a maioria dos pacientes apresentaram algumas limitações nas respostas cardio-respiratórias, indicando realização de exercício exaustivo, mas apresentaram capacidade de realização de exercício induzido artificialmente, possivelmente devido aos benefícios da EENM.The objective of this study was to investigate cardiorespiratory responses (Heart Rate, Blood Pressure, VO2, VCO2 e Ve to Neuromuscular Electrical Stimulation (NMES of the quadriceps in patients with spinal cord injury. Ten patients (five paraplegics and five tetraplegics participated in this study. The protocol of the test consisted of ten minutes of rest, twenty minutes of NMES of the quadriceps and ten minutes of recovery. The findings in this study indicated that, during NMES, the patients demonstrated low levels of VO2 and VCO2 and slow gas kinetics for tetraplegic individuals, and a fast gas kinetics for paraplegic individuals. Moreover, there were increases in blood pressure and heart rate. Cardiorespiratory responses increased with descending spinal cord injury level, meaning that the more severe the lesion, the lower the values. Therefore, most of the patients presented some limitations

      Full Text Available A qualidade da água é muito importante para a saúde e bem-estar do ser humano e o sistema de abastecimento público deve fornecer água de qualidade e em quantidade suficiente para toda a população. As estações de tratamento de água constituem o principal caminho para obtenção de água de qualidade. Quando isso não ocorre vários problemas podem afetar a população que passa a consumir água com qualidade inadequada e com o risco constante de surgimento de várias doenças. A eliminação de micro-organismos em água tratada reduz a competição, favorecendo a multiplicação de bactérias resistentes ao cloro como as do gênero Mycobacterium frequentemente isoladas de águas tratadas e cloradas. Considerando a não indicação da pesquisa de micobactérias nos exames laboratoriais de rotina para controle de qualidade de água para consumo humano e outros usos, o objetivo deste trabalho foi verificar a presença, isolar e identificar as micobactérias ambientais no sistema de abastecimento de água de origem superficial da cidade de Araraquara – SP. Foram analisadas 40 amostras de águas, assim distribuídas: dez de água bruta colhidas na Estação de Tratamento de Água (ETA, dez colhidas após filtração, dez colhidas no reservatório após cloração e dez na rede de distribuição. Foram recuperados 43 isolados de micobactérias. Todos os isolados foram submetidos ao PCR-PRA. As espécies de micobactérias identificadas foram M. lentiflavum, M. parafortuitum, M. genavense, M. gordonae, M. fortuitum, M. confluentis, M. duvalii, M. avium subespécie paratuberculose e M. szulgai. Com esses resultados, concluiu-se que a água é importante fonte de micobactérias ambientais provavelmente relacionadas a várias doenças humanas, sugerindo-se a realização de acompanhamento contínuo desses micro-organismos no sistema de água potável.

      Full Text Available El síndrome de dificultad respiratoria aguda (ARDS se caracteriza por presentar alteraciones severas del intercambio gaseoso (IG causadas por «shunt» e importante irregularidad de la ventilación perfusión (V A/Q. Esto es consecuencia del edema intersticial y el colapso y ocupación alveolar. Además de la fracción inspirada de oxígeno y la evolución de la patología pulmonar, hay distintas variables que son capaces de alterar la presión parcial de oxígeno arterial (PaO2. Es así que los cambios del volumen minuto circulatorio, la concentración de hemoglobina, el consumo de oxígeno o la alcalosis pueden modificar la PaO2 a través de su influencia en la PO2 de sangre venosa mixta. A pesar de la influencia de estas diferentes variables, la anormalidad del IG se ha podido analizar adecuadamente por medio de la técnica de eliminación de múltiples gases inertes (MIGET. Asimismo, se han descripto diversas estrategias ventilatorias (presión positiva de fin de espiración, relaciones inspiratorias-espiratorias invertidas, volúmenes corrientes elevados, etc. que producen mejoría del IG principalmente a través del aumento de la presión media en la vía aérea al reclutar áreas pulmonares previamente colapsadas. También el cambio de decúbito a posición ventral, por modificaciones en la distribución de presión pleural regional, disminuye el colapso alveolar con mejoría de la PaO2. Asimismo hay distintas intervenciones farmacológicas capaces de mejorar el IG tales como la administración de óxido nítrico (ON o de prostaglandinas (PGI2 o PGE1 por vía inhalatoria. Estas producen vasodilatación de las áreas bien ventiladas aumentando el flujo cardíaco a ese nivel y disminuyendo relativamente el flujo por las áreas de «shunt». La almitrina endovenosa, droga vasoconstrictora pulmonar, mejora el IG al aumentar la vasoconstricción hipóxica. Se ha demostrado efecto aditivo de la almitrina con la inhalación de ON. A pesar del

      The relationship between arterial stiffness, measured as pulse wave velocity (PWV), and the left ventricle is confounded by the effects of blood pressure. We evaluated the relationship between carotid-femoral PWV and cardio-ankle vascular index (CAVI), a less pressure-dependent measurement of the stiffness constant (β) of the aorta and the iliac, femoral and tibial arteries, and obtained prognostically relevant measurements of left ventricular structure and systolic function. CAVI, carotid-femoral PWV and echocardiographic left ventricular mass and systolic function were determined in 133 subjects with either hypertension or high-normal blood pressure (33% treated; 56 ± 16 years, blood pressure 145/89 ± 21/12 mm Hg). Carotid-femoral PWV exhibited a direct relationship with systolic and diastolic blood pressure (r = 0.33/0.26, P 0.1). Both CAVI and PWV correlated significantly with left ventricular mass index (r = 0.31, P0.1). In a multivariate regression model, CAVI was independently associated with inappropriate left ventricular mass (β = 0.40, P < 0.001), along with body mass index. CAVI also demonstrated a negative relationship with left ventricular midwall fractional shortening (r = -0.41, P = 0.001) that was independent of age, sex, blood pressure and left ventricular mass in a multivariate analysis. In conclusion, a high CAVI is associated with inappropriately high left ventricular mass and low midwall systolic function. As a marker of arterial diastolic-to-systolic stiffening, CAVI may have a relationship with left ventricular structure and function that is independent of blood pressure levels.

      Oculo-facio-cardio-dental (OFCD) syndrome is a rare X-linked disorder mainly manifesting in females. Patients show ocular, facial, cardiac, and dental abnormalities. OFCD syndrome is caused by heterozygous mutations in the BCOR gene, located in Xp11.4, encoding the BCL6 co-repressor. We report a Croatian family with four female members (grandmother, mother and monozygotic female twins) diagnosed with OFCD syndrome who carry the novel BCOR mutation c.4438C>T (p.R1480*). They present high intrafamilial phenotypic variability with special regard to cardiac defect and cataract that showed more severe disease expression in successive generations. Clinical and radiographic examination of the mother of the twins revealed a talon cusp involving the permanent maxillary right central incisor. This is the first known report of a talon cusp in OFCD syndrome with a novel mutation in the BCOR gene.

      Full Text Available Abstract Background Chronic inflammation may contribute to insulin resistance (IR, metabolic syndrome and atherosclerosis although evidence of causality is lacking in humans. We hypothesized that very low-dose experimental endotoxemia would induce adipose tissue inflammation and systemic IR during a low-grade but asymptomatic inflammatory response and thus provide an experimental model for future tests of pharmacologic and genomic modulation of cardio-metabolic traits in humans. Methods Ten healthy, human volunteers (50% male, 90% Caucasian, mean age 22.7 ± 3.8 were randomized in a double-masked, placebo-controlled, crossover study to separate 36-hour inpatient visits (placebo versus intravenous-LPS 0.6 ng/kg. We measured clinical symptoms via the McGill pain questionnaire and serial vital signs. Plasma and serum were collected for measurement of cytokines, C-reactive protein, insulin and glucose, serial whole blood & subcutaneous adipose tissue mRNA expression were measured by real-time PCR. HOMA-IR, a well-validated measure of IR was calculated to estimate insulin resistance, and frequently sampled intravenous glucose tolerance testing (FSIGTT was performed to confirm an insulin resistant state. We performed ANOVA and within subject ANOVA to understand the differences in cytokines, adipose tissue inflammation and IR before and after LPS or placebo. Results There was no significant difference between placebo and LPS in clinical responses of symptom scores, body temperature or heart rate. However, low-dose endotoxemia induced a rapid and transient 25-fold induction of plasma TNF-alpha and 100-fold increase in plasma IL-6 (Figure 1B (p p p = 0.01 increased with MCP-1 (peak 10-fold, F = 5.6, p p p p  Conclusions We present a low dose human endotoxemia model of inflammation which induces adipose tissue inflammation and systemic insulin resistance in the absence of overt clinical response.

      Mitochondrial homeostasis is essential for maintaining healthy cellular function and survival. The detrimental involvement of mitochondrial dysfunction in neuro-degenerative diseases has recently been highlighted in human conditions, such as Parkinson's, Alzheimer's and Huntington's disease. Friedreich's ataxia (FA) is another neuro-degenerative, but also cardio-degenerative condition, where mitochondrial dysfunction plays a crucial role in disease progression. Deficient expression of the mitochondrial protein, frataxin, is the primary cause of FA, which leads to adverse alterations in whole cell and mitochondrial iron metabolism. Dys-regulation of iron metabolism in these compartments, results in the accumulation of inorganic iron deposits in the mitochondrial matrix that is thought to potentiate oxidative damage observed in FA. Therefore, the maintenance of mitochondrial homeostasis is crucial in the progression of neuro-degenerative conditions, particularly in FA. In this review, vital mitochondrial homeostatic processes and their roles in FA pathogenesis will be discussed. These include mitochondrial iron processing, mitochondrial dynamics (fusion and fission processes), mitophagy, mitochondrial biogenesis, mitochondrial energy production and calcium metabolism.

      Full Text Available INTRODUCCIÓN. El uso inapropiado de ventilación mecánica en el síndrome de dificultad respiratoria aguda puede amplificar la lesión primaria y complicarse con un escape aéreo persistente, capaz de opacar el pronóstico. La ventilación de alta frecuencia oscilatoria es una modalidad disponible para el rescate de un escape aéreo refractario a ventilación mecánica convencional. Este trabajo tiene como objetivo reportar el efecto de este soporte ventilatorio sobre el intercambio gaseoso y evolución del escape aéreo en pacientes con síndrome de dificultad respiratoria aguda MÉTODOS. Se aplicó este soporte ventilatorio a todos los pacientes que ingresaron entre 1999 y 2006 a causa de síndrome de dificultad respiratoria aguda, con barotrauma persistente o recurrente, que alteró el intercambio gaseoso. Se describió el tiempo de persistencia del escape aéreo y la morbilidad y mortalidad para este grupo. RESULTADOS. Se ventilaron 19 pacientes, cuya mediana de edad fue de 17 meses. Antes de comenzar la ventilación, la PaO2/FiO2 fue de 66; el índice de oxigenación de 24 y la PaCO2, de 75 mm Hg. La duración de esta presentó una mediana de 111 h. Se abolió el escape aéreo en un 79 % de los casos y pudo mejorar significativamente el intercambio gaseoso. La sobrevida a los 30 días fue del 89 %. CONCLUSIONES. La ventilación de alta frecuencia es útil en la mayoría de los pacientes afectos de este síndrome complicado con barotrauma refractario y constituye una opción terapéutica indiscutible.INTRODUCTION: The inappropriate use of mechanical ventilation in acute respiratory distress syndrome may increase the primary lesion and complicate it with a persistent air leak capable of obscuring the diagnosis. The oscillatory high frequency ventilation is an available modality to rescue a refractory air leak at conventional mechanical ventilation. The aim of this paper is to report the effect of this ventilatory support on gas exchange

      Full Text Available As new as very promising technique, breath analysis allows for monitoring the biochemical processes that occur in human body in a non-invasive way. Nevertheless, the high costs for standard analytical instrumentation (i.e., gas chromatograph, mass spectrometer, the need for specialized personnel able to read the results and the lack of protocols to collect breath samples, set limit to the exploitation of breath analysis in clinical practice. Here, we describe the development of a device, named Wize Sniffer, which is portable and entirely based on low cost technology: it uses an array of commercial, semiconductor gas sensors and a widely employed open source controller, an Arduino Mega2560 with Ethernet module. In addition, it is very easy-to-use also for non-specialized personnel and able to analyze in real time the composition of the breath. The Wize Sniffer is composed of three modules: signal measurement module, signal conditioning module and signal processing module. The idea was born in the framework of European SEMEiotic Oriented Technology for Individual's CardiOmetabolic risk self-assessmeNt and Self-monitoring (SEMEOTICONS Project, in order to monitor individual's lifestyle by detecting in the breath those molecules related to the noxious habits for cardio-metabolic risk (alcohol intake, smoking, wrong diet. Nonetheless, the modular configuration of the device allows for changing the sensors according to the molecules to be detected, thus fully exploiting the potential of breath analysis.

      Cardio-facio-cutaneous (CFC) syndrome is a sporadic multiple congenital anomalies/mental retardation condition principally caused by mutations in BRAF, MEK1, and MEK2. Mutations in KRAS and SHOC2 lead to a phenotype with overlapping features. In approximately 10–30% of individuals with a clinical diagnosis of CFC, a mutation in one of these causative genes is not found. Cardinal features of CFC include congenital heart defects, a characteristic facial appearance, and ectodermal abnormalities. Additional features include failure to thrive with severe feeding problems, moderate to severe intellectual disability and short stature with relative macrocephaly. First described in 1986, more than 100 affected individuals are reported. Following the discovery of the causative genes, more information has emerged on the breadth of clinical features. Little, however, has been published on genotype–phenotype correlations. This clinical study of 186 children and young adults with mutation-proven CFC syndrome is the largest reported to date. BRAF mutations are documented in 140 individuals (approximately 75%), while 46 (approximately 25%) have a mutation in MEK 1 or MEK 2. The age range is 6 months to 32 years, the oldest individual being a female from the original report [Reynolds et al. (1986); Am J Med Genet 25:413–427]. While some clinical data on 136 are in the literature, 50 are not previously published. We provide new details of the breadth of phenotype and discuss the frequency of particular features in each genotypic group. Pulmonary stenosis is the only anomaly that demonstrates a statistically significant genotype–phenotype correlation, being more common in individuals with a BRAF mutation.

      During recent decades there has been a rapidly growing interest in youths' sedentary behaviour and its association with cardio-metabolic health. Currently there is little-to-no evidence for a cross-sectional and longitudinal association between volume and pattern (bouts and breaks) of objectively measured sedentary behavior and body weight in youth. Likewise, there is little-to-no evidence for a cross-sectional association between volume and pattern of objectively measured sedentary behavior and other markers for cardio-metabolic risk in youth. However, there is sufficient evidence for a cross-sectional and longitudinal association between screen-time and body weight and blood pressure and blood lipids. Furthermore, there is evidence for a cross-sectional association between youths' screen-time and clustered metabolic risk and insulin resistance. Overall, the level of evidence was low and, therefore, caution is required when interpreting the results.

      Cardio-metabolic syndrome (CMS) is a highly prevalent condition. There is an urgent need to identify effective and integrated multi-disciplinary approaches that can reduce risk factors for CMS. Sixty-two patients with a history of CMS were randomized 1:1 into two groups: a standard information -only group (control), or a self-regulated lifestyle waist circumference (patient-centered cognitive behavioral therapy) intervention group. A pretest and posttest, controlled, experimental design was used. Outcomes were measured at the baseline (week 0) and at the end of intervention (week 12). Comparisons were drawn between groups and over time. The mean (standard deviation) age of the subjects was 48.6 (5.8) years ranging from 32 to 63, and 56.9% of the participants were female. Both groups showed no significant differences in Demographic variables and the metabolic syndrome indicators at baseline. While the control group only showed modest improvement after 12 weeks, compared to baseline, the intervention group demonstrated significant improvement from baseline. This study controlled for patients' demographics and baseline characteristics when assessing the effects of intervention. After adjusting for age, education and baseline level, the experimental group and the control group were statistically significant different in the following post-treatment outcomes: WC (F = 35.96, P cognitive behavioral therapy can improve the physical and mental health conditions among individuals reporting a history of cardio-metabolic syndrome, and possibly provided preliminary benefits for the treatment of CMS.

      Full Text Available Gestational Diabetes Mellitus (GDM and vitamin D deficiency are related to insulin resistance and impaired beta cell function, with heightened risk for future development of diabetes. We evaluated the impact of vitamin D supplementation on markers of glucose metabolism and cardio metabolic risk in Asian women with former GDM and hypovitaminosis D. In this double blind, randomized controlled trial, 26 participants were randomized to receive either daily 4000 IU vitamin D3 or placebo capsules. 75 g Oral Glucose Tolerance Test (OGTT and biochemistry profiles were performed at baseline and 6 month visits. Mathematical models, using serial glucose, insulin and C peptide measurements from OGTT, were employed to calculate insulin sensitivity and beta cell function. Thirty three (76% women with former GDM screened had vitamin D level of <50 nmol/L at baseline. Supplementation, when compared with placebo, resulted in increased vitamin D level (+51.1 nmol/L vs 0.2 nmol/L, p<0.001 and increased fasting insulin (+20% vs 18%, p = 0.034. The vitamin D group also demonstrated a 30% improvement in disposition index and an absolute 0.2% (2 mmol/mol reduction in HbA1c. There was no clear change in insulin sensitivity or markers of cardio metabolic risk. This study highlighted high prevalence of vitamin D deficiency among Asian women with former GDM. Six months supplementation with 4000 IU of vitamin D3 safely restored the vitamin D level, improved basal pancreatic beta-cell function and ameliorated the metabolic state. There was no effect on markers of cardio metabolic risk. Further mechanistic studies exploring the role of vitamin D supplementation on glucose homeostasis among different ethnicities may be needed to better inform future recommendations for these women with former GDM at high risk of both hypovitaminosis D and future diabetes.

      Full Text Available Aim: To assess the efficacy of cardio-metabolic diseases treatment, the compliance to treatment, and to evaluate the obtained results compared to the previous published ones.Methods: A screening was conducted in the military population, including male and female with age at least 20 years, with of without: diabetes, impaired fasting glucose, obesity, hypertension, dyslipidemia. The anthropometrics parameters, body fat percent, and blood pressure were evaluated. The following data were collected: glycemia, lipid profile, renal and hepatic function, level of physical activity, smoking status, personal associated diseases. The compliance to treatment was noted in percentages declared by patient in a survey. The IRIS 2 score of insulin resistance and cardiovascular risk using EURO’98 charts, Framingham Score and SCORE system were calculated. The metabolic syndrome diagnosis was performed using the International Diabetes Federation 2005 criteria. Results: 338 persons were investigated; the majority were males, 192 with normal glycemia. The objectives of the treatment were reached in < 50% cases for each pathological aspect. A negative correlation was found between anthropometric parameters and the compliance to diet and physical exercise, and positive correlation between bodyweight, high cardiovascular risk and medication. The study showed the same pattern of the treatment as in other studies, with a low compliance to medical nutrition therapy and with low percentage in witch the objective for cardio-metabolic pathology are reached. Conclusions: An active and sustained attitude is necessary to promote a healthy lifestyle in the respect of improvement of treatment and prevention of metabolic and cardiovascular morbidity and mortality.

      Transcatheter treatment has become the method of choice for treating many heart defects. Recently, Cardio-O-Fix occluder (COF) - a new, self-expandable nitinol wire-mesh device very similar to the Amplatzer device - has been introduced into clinical practice. To the best of our knowledge, this is the first publication related to its application. Five patients aged from six months to 69 years were included in the study: two with atrial septal defect (ASD), one with patent foramen ovale (PFO) after cryptogenic stroke, and two with patent ductus arteriosus (PDA). These latter two comprised one six month old infant with co-existent hypertrophied cardiomyopathy, and a 53 year-old woman with recanalized PDA after previous ligation. All were treated percutaneously with COF. There was no preliminary patient selection. The only limitation was the size of the devices in our possession (16 and 22 mm ASD COF, 25 PFO COF, 4/6 and 6/8 PDA COF). The implantation technique was the same as previously described for Amplatzer occluders. All procedures were finished successfully with complete closure of the shunt. No complications were observed during a six month follow-up. In the child with PDA, we observed decrease of gradient from 80 to 60 mm Hg in hypertrophied left ventricular outflow tract, although a small protrusion of PDA-COF device was noted in the descending aorta (8 mm Hg gradient in ECHO). In the patient with recanalized PDA, the procedure was performed after arterio-venous loop creation. Mean fluoroscopy time was 4.4 (range from 1.6 to 11) minutes. Our preliminary experience indicates that the application of Cardio-O-Fix devices is safe and effective.

Se trasplantaron plántulas de 35 días, que fueron inoculadas dos semanas después del trasplante. La aplicación de vermicompost provocó un aumento significativo del peso fresco foliar y del peso seco foliar y radical; a mayor dosis, mayor fue el incremento. Las plantas de todos los tratamientos que incluyeron inoculación con P. capsici presentaron síntomas de la enfermedad en la raíz. Los valores de incidencia y severidad fueron mayores para el tratamiento con 50% de abono. En este tratamiento se presentaron síntomas de marchitez. La ausencia de diferencias en las variables de peso fresco y seco entre los tratamientos inoculados y sin inocular, a los que se adicionó abono al 25%, sugiere que esta dosis podría compensar el daño causado por el patógeno. Se observó una menor concentración de nutrimentos en los tejidos de las plantas inoculadas lo que indica que el daño causado a la raíz pudo haber afectado la adquisición de nutrimentos.

This article describes the content and delivery of this program, with information on compliance and acceptability. Methods Overweight/obese adults (n = 153 with metabolic syndrome were recruited from the community and randomly allocated to intervention (INT or control (CON. Written copies of Australian national dietary and PA guidelines were provided to all participants. INT took part in a 16-week lifestyle program which provided a curriculum and practical strategies on 1 dietary and PA information based on national guidelines, 2 behavioural self-management tools, 3 food-label reading, supermarkets tour and cooking, 4 exercise sessions, and 5 peer-group support. Compliance was assessed using attendance records and weekly food/PA logs. Participants' motivations, perceived benefits and goals were assessed through facilitated discussion. Program acceptability feedback was collected through structured focus groups. Results Although completion of weekly food/PA records was poor, attendance at information/education sessions (77% overall and exercise participation (66% overall was high, and compared with CON, multiple markers of body composition and cardio-metabolic health improved in INT. Participants reported that the most useful program components included food-label reading, cooking sessions, and learning new and different physical exercises, including home-based options.

      Arterial stiffness is an independent predictor for vascular diseases. Cardio-ankle vascular index (CAVI) is a new index of arterial stiffness. In the present study, we investigated the possible risk factors involving CAVI in hypertension and diabetes mellitus (DM) subjects. One thousand sixty-three subjects (M/F 533/530) from Shougang Corporation Examination Center were divided into four groups: healthy group (n = 639); hypertension group (n = 312); DM group (n = 58); and hypertension with DM group (n = 54). CAVI was measured by VS-1000 apparatus. Our results showed that CAVI was significantly higher in hypertension subjects with DM than in healthy and hypertension group, respectively (8.59 ± 1.08 vs 7.23 ± 1.10; 8.59 ± 1.08 vs 7.94 ± 1.33; both P hypertension subjects with DM compared with healthy and hypertension groups.

      Hyperactive platelets, in addition to their roles in thrombosis, are also important mediators of atherogenesis. Antiplatelet drugs are not suitable for use where risk of a cardiovascular event is relatively low. It is therefore important to find alternative safe antiplatelet inhibitors for the vulnerable population who has hyperactive platelets in order to reduce the risk of cardiovascular disease. Potent antiplatelet factors were identified in water-soluble tomato extract (Fruitflow ® ), which significantly inhibited platelet aggregation. Human volunteer studies demonstrated the potency and bioavailability of active compounds in Fruitflow ® . Fruitflow ® became the first product in Europe to obtain an approved, proprietary health claim under Article 13(5) of the European Health Claims Regulation 1924/2006 on nutrition and health claims made on foods. Fruitflow ® is now commercially available in different countries worldwide. In addition to its reduction in platelet reactivity, Fruitflow ® contains anti-angiotensin-converting enzyme and anti-inflammatory factors, making it an effective and natural cardio-protective functional food.

      Full Text Available Identified as a treasure of natural herbal products, traditional Chinese medicine (TCM has attracted extensive attention for their moderate treatment effect and lower side effect. Cardio-cerebrovascular diseases (CCVD are a leading cause of death. TCM is used in China to prevent and treat CCVD. However, the complexity of TCM poses challenges in understanding the mechanisms of herbs at a systems-level, thus hampering the modernization and globalization of TCM. A novel model, termed traditional Chinese medicine systems pharmacology (TCMSP analysis platform, which relies on the theory of systems pharmacology and integrates absorption, distribution, metabolism, excretion and toxicity (ADME/T evaluation, target prediction and network/pathway analysis, was proposed to address these problems. Here, we review the development of systems pharmacology, the TCMSP approach and its applications in the investigations of CCVD and compare it with other methods. TCMSP assists in uncovering the mechanisms of action of herbal formulas used in treating CCVD. It can also be applied in ascertaining the different syndrome patterns of coronary artery disease, decoding the multi-scale mechanisms of herbs, and in understanding the mechanisms of herbal synergism.

      In patients with cancer receiving potentially cardio-toxic chemotherapy, measurements of left ventricular (LV) circumferential or longitudinal strain are often used clinically to identify myocardial dysfunction. Using a new software algorithm, we sought to determine in individuals receiving treatment for cancer the association between automated assessments of LV mean mid-wall circumferential strain and conventional measures of LV ejection fraction (EF) both obtained from cardiovascular magnetic resonance (CMR) cine balanced steady-state free-precession (bSSFP) white-blood acquisitions. Before and 3 months after initiating treatment with potentially cardio-toxic chemotherapy, 72 individuals (aged 54 ± 14 years with breast cancer [39%], lymphoma [49%], or sarcoma [12%]) underwent serial CMR cine bSSFP assessments of LV volumes and EF, and mean mid-wall circumferential strain determined from these same cine images as well as from additional tagged CMR images. On the cine images, assessments of strain were obtained using the newly developed deformation-based segmentation algorithm. Assessments of LV volumes/EF from the cine images and strain from tagged CMR were accomplished using commercially available software. All measures were analyzed in a blinded fashion independent of one another. Acceptable measures for the automated assessments of mean mid-wall circumferential strain from the cine images were obtained in 142 of 144 visits (98.6%) with an overall analysis time averaging 6:47 ± 1:06 min. The results from these automated measures averaged -18.8 ± 2.9 at baseline and -17.6 ± 3.1 at 3 months (p = 0.001). Left ventricular EF declined slightly from 65 ± 7% at baseline to 62 ± 7% at 3 months (p = 0.0002). The correlation between strain from cine imaging and LVEF was r = -0.61 (p cine and tagged derived assessments of strain was r = 0.23; p = 0.01. Automated measures of LV mean mid-wall circumferential strain can be obtained in 6

      Full Text Available La Sociedad Argentina de Infectología convocó a otras sociedades científicas para elaborar una guía práctica y actualizada para el manejo del tratamiento antibiótico de las bronquitis agudas (BA y los episodios de reagudización de enfermedad pulmonar obstructiva crónica (EPOC, con el objetivo de promover el uso racional de los recursos diagnósticos y terapéuticos. La BA se caracteriza por la inflamación del árbol bronquial que afecta tanto a adultos como a niños sin enfermedades pulmonares crónicas, siendo de origen viral en la mayoría de los casos. El diagnóstico es clínico, debiéndose diferenciar de los episodios de neumonía adquirida en la comunidad. El tratamiento de los episodios de BA es fundamentalmente sintomático. En huéspedes inmunocomprometidos, con enfermedades crónicas respiratorias o cardíacas y en adultos mayores con comorbilidades debe evaluarse el requerimiento de tratamiento antibiótico caso por caso. Se define como exacerbación de la EPOC al cambio agudo en la situación clínica basal del paciente más allá de la variabilidad diaria, que cursa con aumento de la disnea, aumento de la expectoración, expectoración purulenta, o cualquier combinación de estos tres síntomas, y que precisa un cambio terapéutico. La presencia de uno de estos síntomas se define como episodio leve, dos como moderado y tres como grave. En un 50 a 75% de las exacerbaciones de EPOC se aísla en el esputo un agente infeccioso. En los episodios moderados y graves debe iniciarse tratamiento antibiótico. Amoxicilina-inhibidor de betalactamasas, macrólidos y fluoroquinolonas se encuentran entre las opciones terapéuticas.

      Non-communicable diseases (NCDs) including diabetes, obesity and cardiovascular disease are the leading causes of death worldwide. Indigenous populations are disproportionally affected. In an effort to halt the increasing disease burden, the mechanisms underlying the increasing rate of NCDs are an important area of study. Recent evidence has focused on the perinatal period as an influential period impacting the future cardio-metabolic health of the offspring. This concept has been defined as metabolic foetal programming and supports the importance of the developmental origins of health and disease in research and clinical practice, specifically in prevention efforts to protect future generations from NCDs. An understanding of the underlying mechanisms involved is not clear as of yet. However, an understanding of these mechanisms is imperative in order to plan effective intervention strategies. As much of the discussion below is gleaned from large epidemiological studies and animal studies, further research with prospective cohorts is necessary. Copyright © 2014. Published by Elsevier Ltd.

      We report two patients with velo-cardio-facial syndrome (VCFS) who were admitted to our pediatric endocrinology clinic because of short stature and followed longitudinally until attainment of final height. Both patients followed a growth pattern consistent with constitutional delay of puberty with normal and near normal final height. Case 2 also had partial growth hormone (GH) deficiency and severe short stature (height SDS -3.4 SDS), but showed spontaneous catch-up and ended up with a final height of -2 SDS. These cases suggest that short stature in children with VCFS is due to a pattern of growth similar to that observed in constitutional delay of growth and puberty.

      Full Text Available Road traffic accident victims, as well as persons experiencing cardiac and other medical emergencies, might lose their lives due to the non-availability of trained personnel to provide effective cardio-pulmonary resuscitation (CPR with functional equipment and adequate resources.The objectives of the study were to identify unit managers’ perceptions about challenges encountered when performing CPR interventions in the two referral public hospitals in Botswana. These results could be used to recommend more effective CPR strategies for Botswana’s hospitals. Interviews, comprising two quantitative sections with closed ended questions and one qualitative section with semi-structured questions, were conducted with 22 unit managers. The quantitative data indicated that all unit managers had at least eight years’ nursing experience, and could identify CPR shortcomings in their hospitals. Only one interviewee had never performed CPR. The qualitative data analysis revealed that the hospital units sometimes had too few staff members and did not have fully equipped emergency trolleys and/or equipment. No CPR teams and no CPR policies and guidelines existed. Nurses and doctors reportedly lacked CPR knowledge and skills. No debriefing services were provided after CPR encounters. The participating hospitals should address the following challenges that might affect CPR outcomes: shortages of staff, overpopulation of hospital units, shortcomings of the emergency trolleys and CPR equipment, absence of CPR policies and guidelines, absence of CPR teams, limited CPR competencies of doctors and nurses and the lack of debriefing sessions after CPR attempts.

    11. Continual low-level MEK inhibition ameliorates cardio-facio-cutaneous phenotypes in zebrafish

      Corina Anastasaki

      2012-07-01

      Cardio-facio-cutaneous (CFC syndrome is caused by germline mutations in KRAS, BRAF and MEK1/2. The highly selective and potent MEK inhibitors that have been developed as anti-cancer agents hold potential as therapeutics for CFC syndrome. We have previously shown that the effects of CFC mutations on zebrafish gastrulation can be prevented by a 1-hour treatment with MEK inhibitors within a specific developmental time-window. However, MEK activity is essential for normal development and PD0325901 treatment outside this treatment window leads to additional developmental defects in MEK-dependent tissues. We now test ten different doses of PD0325901 at six developmental time points and assess the effects on body axis length, heart development and craniofacial structures in zebrafish embryos. Notably, we find that a continuous low-level dose of PD0325901 that has only minor inhibition of MEK activity can prevent the action of both the common CFC BRAFQ257R kinase-active allele and the BRAFG596V kinase-impaired mutant allele through the first 5 days of development. These results provide a detailed study of the effects of PD0325901 in development and show that, unlike in cancer, which requires robust inhibition of MAPK signalling, a partial reduction in phospho-ERK1/2 activity is sufficient to moderate the developmental effects of BRAFCFC mutations.

      To assess the effects of brain movements induced by heartbeat on dose distributions in synchrotron micro- and mini-beam radiaton therapy and to develop a model to help guide decisions and planning for future clinical trials. The Monte Carlo code PENELOPE was used to simulate the irradiation of a human head phantom with a variety of micro- and mini-beam arrays, with beams narrower than 100 μm and above 500 μm, respectively, and with radiation fields of 1cm × 2cm and 2cm × 2cm. The dose in the phantom due to these beams was calculated by superposing the dose profiles obtained for a single beam of 1μm × 2cm. A parameter δ, accounting for the total displacement of the brain during the irradiation and due to the cardio-synchronous pulsation, was used to quantify the impact on peak-to-valley dose ratios and the full-width at half-maximum. The difference between the maximum (at the phantom entrance) and the minimum (at the phantom exit) values of the peak-to-valley dose ratio reduces when the parameter δ increases. The full-width at half-maximum remains almost constant with depth for any δ value. Sudden changes in the two quantities are observed at the interfaces between the various tissues (brain, skull and skin) present in the head phantom. The peak-to-valley dose ratio at the center of the head phantom reduces when δ increases, remaining above 70% of the static value only for mini-beams and δ smaller than ~ 200 μm. Optimal setups for brain treatments with synchrotron radiation micro- and mini-beam combs depend on the brain displacement due to cardio-synchronous pulsation. Peak-to-valley dose ratios larger than 90% of the maximum values obtained in the static case occur only for mini-beams and relatively large dose rates. This article is protected by copyright.

      Arousal from sleep is an important protective response to hypoxia that becomes rapidly depressed in active sleep (AS) when hypoxia is repeated. This study questioned whether there might also be selective depression of cardio-respiratory responses to hypoxia during AS. Nine newborn lambs (7-22 days of age) were studied over three successive nights. The first and third nights were baseline studies (inspired oxygen fraction, Fi,O2= 0.21). During the second night, during every epoch of sleep, lambs were exposed to 60 s episodes of isocapnic hypoxia (Fi,O2= 0.10). During quiet sleep (QS), the probability of arousal in hypoxia exceeded the probability of spontaneous arousal (P ventilatory and blood pressure responses in AS, but not in QS. Selective depression of responses during AS may render the newborn particularly vulnerable to hypoxia in this state. PMID:10457072

      Management of patients treated with CardioWest Total Artificial Heart (CW-TAH) as a bridge to heart transplantation (HTx) is complicated by difficulties in determining the optimal timing of transplantation. We present a case of a 53-year-old man supported as an outpatient with a CW-TAH, whose condition deteriorated following exchange of the portable driver. The patient was followed-up with serial cardiopulmonary exercise testing (CPET) which demonstrated a fall of peak VO2 to below 12 ml/kg/min following driver substitution, and the patient was subsequently treated with urgent orthotopic HTx. This case highlights the potential utility of CPET as a means for monitoring and indicating timing of HTx in patients with CW-TAH, as well as the potential for clinical deterioration following portable driver substitution.

MATERIAL Y MÉTODOS: Se realizó un estudio ecológico transversal para describir la correlación entre las modas promedio mensuales, medias móviles mensuales interpoladas de los contaminantes (monóxido de carbono, dióxido de nitrógeno, ozono, partículas menores de 10 micras y dióxido de azufre y las consultas mensuales registradas por infecciones agudas de las vías respiratorias en niños menores de cinco años. RESULTADOS: Los contaminantes atmosféricos monóxido de carbono y dióxido de nitrógeno muestran correlación significativa con las infecciones agudas de las vías respiratorias en niños menores de cinco años del área urbana de Guadalajara. Las correlaciones presentadas fueron: CO (r= 0.05 y NO2 (r= 0.09. CONCLUSIONES: Pese a que las concentraciones de contaminantes se mantienen por debajo de la norma oficial, los contaminantes monóxido de carbono y dióxido de nitrógeno inciden en la salud de la población infantil del área urbana de Guadalajara. Aunque las modas mensuales y medias móviles mensuales no rebasan la normatividad establecida, sí lo hacen los máximos registrados; esto permite indicar que si bien en la mayor parte del día no hay una exposición potencial de riesgo para la población a los contaminantes, sí existe exposición potencial de riesgo para la población al aire contaminado con concentraciones fuera de la norma durante algunas horas de ciertos días, lo cual puede influir de manera significativa en el incremento de infecciones agudas de las vías respiratorias superiores.OBJECTIVE: To describe the correlation between the concentration levels of atmospheric air pollutants and the number of medical visits

      Full Text Available Panel studies show a consistent association between increase in the cardiovascular hospitalizations with air pollutants in economically developed regions, but little evidence in less developed inland areas. In this study, a time-series analysis was used to examine the specific effects of major air pollutants [particulate matter less than 10 microns in diameter (PM10, sulfur dioxide (SO2, and nitrogen dioxides (NO2] on daily hospital admissions for cardio-cerebrovascular diseases in Lanzhou, a heavily polluted city in China. We examined the effects of air pollutants for stratified groups by age and gender, and conducted the modifying effect of seasons on air pollutants to test the possible interaction. The significant associations were found between PM10, SO2 and NO2 and cardiac disease admissions, SO2 and NO2 were found to be associated with the cerebrovascular disease admissions. The elderly was associated more strongly with gaseous pollutants than younger. The modifying effect of seasons on air pollutants also existed. The significant effect of gaseous pollutants (SO2 and NO2 was found on daily hospital admissions even after adjustment for other pollutants except for SO2 on cardiac diseases. In a word, this study provides the evidence for the detrimental short-term health effects of urban gaseous pollutants on cardio-cerebrovascular diseases in Lanzhou.

Los autores revisan la definición de EPOC, conjuntamente con los últimos conocimientos de la fisiopatología de la enfermedad. Se resume la presentación clínica, diagnóstico por imágenes y evaluación funcional. Se enfatiza la importancia del diagnóstico precoz mediante la exploración funcional y la prevención a través de la cesación del tabaquismo, única medida capaz de alterar la evolución. Se describen las estrategias para dejar de fumar, así como el tratamiento farmacológico y no farmacológico. En el primero, la administración de broncodilatadores inhalados -anticolinérgicos, beta 2 agonistas adrenérgicos o ambos- son la primera opción. Los broncodilatadores de acción prolongada mejoran la adherencia al tratamiento y su efectividad. Los corticoides inhalados se indican en pacientes con marcada obstrucción al flujo aéreo y respuesta conocida a corticoides. Su uso disminuye la frecuencia de las exacerbaciones. La vacunación antigripal anual está recomendada en todos los pacientes. Con respecto a las intervenciones no farmacológicas, la cirugía del enfisema se recomienda en especiales circunstancias. La rehabilitación que incluya ejercicios, kinesioterapia y nutrición, es una herramienta útil en pacientes con limitación en la actividad física habitual. La oxigenoterapia domiciliaria prolongada mejora la sobrevida de pacientes con hipoxemia crónica severa.

      The improvement of insulin sensitivity by exercise has been shown to be inhibited by supplementation of vitamins acting as antioxidants. To examine effects of exercise with or without blueberries, containing natural antioxidants, on cardio-metabolic risk factors. Fifteen healthy men and 17 women, 27.6 ± 6.5 years old, were recruited, and 26 completed a randomized cross-over trial with 4 weeks of exercise by running/jogging 5 km five times/week and 4 weeks of minimal physical activity. Participants were also randomized to consume 150 g of blueberries, or not, on exercise days. Laboratory variables were measured before and after a 5 km running-race at maximal speed at the beginning and end of each period, i.e. there were four maximal running-races and eight samplings in total for each participant. Insulin and triglyceride levels were reduced while HDL-cholesterol increased by exercise compared with minimal physical activity. Participants randomized to consume blueberries showed an increase in fasting glucose levels compared with controls, during the exercise period (blueberries: from 5.12 ± 0.49 mmol/l to 5.32 ± 0.29 mmol/l; controls: from 5.24 ± 0.27 mmol/l to 5.17 ± 0.23 mmol/l, P = 0.04 for difference in change). Triglyceride levels fell in the control group (from 1.1 ± 0.49 mmol/l to 0.93 ± 0.31 mmol/l, P = 0.02), while HDL-cholesterol increased in the blueberry group (from 1.51 ± 0.29 mmol/l to 1.64 ± 0.33 mmol/l, P = 0.006). Ingestion of blueberries induced differential effects on cardio-metabolic risk factors, including increased levels of both fasting glucose and HDL-cholesterol. However, since it is possible that indirect effects on food intake were induced, other than consumption of blueberries, further studies are needed to confirm the findings.

      In sub-Saharan Africa, infectious diseases and malnutrition constitute the main health problems in children, while adolescents and adults are increasingly facing cardio-metabolic conditions. Among adolescents as the largest population group in this region, we investigated the co-occurrence of infectious diseases, malnutrition and cardio-metabolic risk factors (CRFs), and evaluated demographic, socio-economic and medical risk factors for these entities. In a cross-sectional study among 188 adolescents in rural Ghana, malarial infection, common infectious diseases and Body Mass Index were assessed. We measured ferritin, C-reactive protein, retinol, fasting glucose and blood pressure. Socio-demographic data were documented. We analyzed the proportions (95% confidence interval, CI) and the co-occurrence of infectious diseases (malaria, other common diseases), malnutrition (underweight, stunting, iron deficiency, vitamin A deficiency [VAD]), and CRFs (overweight, obesity, impaired fasting glucose, hypertension). In logistic regression, odds ratios (OR) and 95% CIs were calculated for the associations with socio-demographic factors. In this Ghanaian population (age range, 14.4–15.5 years; males, 50%), the proportions were for infectious diseases 45% (95% CI: 38–52%), for malnutrition 50% (43–57%) and for CRFs 16% (11–21%). Infectious diseases and malnutrition frequently co-existed (28%; 21–34%). Specifically, VAD increased the odds of non-malarial infectious diseases 3-fold (95% CI: 1.03, 10.19). Overlap of CRFs with infectious diseases (6%; 2–9%) or with malnutrition (7%; 3–11%) was also present. Male gender and low socio-economic status increased the odds of infectious diseases and malnutrition, respectively. Malarial infection, chronic malnutrition and VAD remain the predominant health problems among these Ghanaian adolescents. Investigating the relationships with evolving CRFs is warranted.

      Cardio-facio-cutaneous syndrome (CFC) is a multiple congenital anomaly/mental retardation syndrome named because of a characteristic facies, cardiac anomalies, and ectodermal abnormalities. While considerable literature describes the main features, few studies have documented the frequencies of less common features allowing a greater appreciation of the full phenotype. We have analysed clinical data on 38 individuals with CFC and a confirmed mutation in one of the genes known to cause the condition. We provide data on well-established features, and those that are less often described. Polyhydramnios (77%) and prematurity (49%) were common perinatal issues. 71% of individuals had a cardiac anomaly, the most common being pulmonary valve stenosis (42%), hypertrophic cardiomyopathy (39%), and atrial septal defect (28%). Hair anomalies were also typical: 92% had curly hair, 84% sparse hair, and 86% absent or sparse eyebrows. The most frequent cutaneous features were keratosis pilaris (73%), hyperkeratosis (61%) and nevi (76%). Significant and long lived gastrointestinal dysmotility (71%), seizures (49%), optic nerve hypoplasia (30%) and renal anomalies, chiefly hydronephrosis (20%), were among the less well known issues reported. This study reports a broad range of clinical issues in a large cohort of individuals with molecular confirmation of CFC.

      Over the past two decades, there have been a lot of advances in the field of pattern analyses for biomedical signals, which have helped in both medical diagnoses and in furthering our understanding of the human body. A relatively recent area of interest is the utility of biomedical signals in the field of biometrics, i.e., for user identification. Seminal work in this domain has already been done using electrocardiograph (ECG) signals. In this paper, we discuss our ongoing work in using a relatively recent modality of biomedical signals-a cardio-synchronous waveform measured using a Radio-Frequency Impedance-Interrogation (RFII) device for the purpose of user identification. Compared to an ECG setup, this device is noninvasive and measurements can be obtained easily and quickly. Here, we discuss the feasibility of reducing the dimensions of these signals by projecting onto various subspaces while still preserving interuser discriminating information. We compare the classification performance using classical dimensionality reduction methods such as principal component analysis (PCA), independent component analysis (ICA), random projections, with more recent techniques such as K-SVD-based dictionary learning. We also report the reconstruction accuracies in these subspaces. Our results show that the dimensionality of the measured signals can be reduced by 60 fold while maintaining high user identification rates.

      atherogenic form to the larger, less damaging particle size, have also been noted. ω3 LC-PUFA are effective modulators of the inflammation that accompanies several cardio-metabolic abnormalities. Taking into consideration the pleiotropic nature of their actions, it can be concluded that dietary supplementation with ω3 LC-PUFA will lead to improvements in cardio-metabolic health parameters. These fatty acids pose only minor side effects and more importantly, do not interact adversely with the common drug therapies used in the management and treatment of hypertension, dyslipidemia, type-2 diabetes, and obesity/metabolic syndrome, but in some instances work synergistically, thereby providing additional cardiovascular benefits.

OBJECTIVE: To determine the presence of cardiovascular risk (obesity and hypertension in schoolchildren and its potential interactions with cardio-respiratory fitness. METHODS: This was a cross-sectional study conducted in a stratified cluster sample of 1,666 schoolchildren, aged between 7 and 17 years, 873 (52.4% of them male and 793 (47.6% of them female. The following variables were evaluated: systolic blood pressure (SBP, diastolic blood pressure (DBP, body mass index (BMI, body fat percentage (BF %, and cardio-respiratory fitness. SBP and DBP were correlated with waist circumference (WC, waist-hip ratio (WHR, sum of skin folds (ΣSF, and cardio-respiratory fitness. RESULTS: A BMI assessment of the students showed that 26.7% of them were overweight or obese, and 35.9% had body fat percentage over moderately high. As to blood pressure, we found that 13.9% and 12.1% of the students were borderline or hypertensive, for SBP and DBP, respectively. There was an association among hypertension, obesity, and cardio-respiratory fitness. There was a significant correlation of SBP and DBP with all variables, and also a weak to moderate correlation with age, weight, height, BMI, and waist circumference. CONCLUSION: The presence of hypertension associated with obesity and its effects on cardio-respiratory fitness stress the importance of recommending, since childhood, a more active and healthy lifestyle.

Redução nos valores do ângulo de contato, aumento no trabalho de adesão e aumento no ensaio de resistência ao descascamento (EPDM × Poliuretano foram observados após tratamento com Ar e N2/H2, resultando em melhora nas propriedades adesivas da superfície tratada.The surface of a vulcanized ethylene propylene diene monomer (EPDM rubber was modified by microwave plasma in Ar, Ar/O2, N2/O2 and N2/H2 in order to improve the adhesion properties. Surface modification was characterized by FT-IR/UATR, because this technique showed smaller interference of ingredients of EPDM formulation in comparison with other techniques used (ATR KRS-5 and Ge. Oxygenated groups were introduced in the EPDM surface after treatment, even in treatments without oxygen. Theses groups were formed when the activated surface was exposed to the atmosphere. In treatments with nitrogen, oxygenated and possible nitrogenated groups were identified by FT-IR. Reduction in the contact angle, increase in the work of adhesion and increase in the peel strength (EPDM × Polyurethane were observed after treatment with Ar and N2/H2, resulting in improved adhesion properties of the modified surface.

      We report on a female with a interstitial deletion of 10p13 and a phenotype similar to that seen with the 22q deletion syndromes (DiGeorge/velo-cardio-facial). She had a posterior cleft palate, perimembranous ventricular septal defect, dyscoordinate swallowing, T-cell subset abnormalities, small ears, maxillary and mandibular hypoplasia, broad nasal bridge, deficient alae nasi, contractures of fingers and developmental delay. This could indicate homology of some developmental genes at 22q and 10p so that patients with the velocardiofacial phenotype who do not prove to be deleted on 22q are candidates for a 10p deletion. 58 refs., 3 figs.

      The capability of respiratory sinus arrhythmia (RSA) to generate privileged locations for the occurrence of R-peaks within the respiratory cycle has been questioned in recent works, challenging the hypothesis that RSA might play a role in improving pulmonary gas exchange. We assessed such a capability submitting healthy humans to spontaneous and paced breathing (SB and PB) protocols, estimating the fraction of beats occurring during inspiration, at low, medium, and high respiratory volumes, and during the first and second half of inspiration and expiration. Then, the same fractions were computed assuming a random uniform distribution of heartbeats, and the differences were compared. The results found are as follows: (1) during PB at 6 rpm, heartbeats redistribute toward inspiration; (2) during SB and PB at 12 rpm, heartbeats tend to cluster when respiratory volume is high; (3) since such redistributions are limited in magnitude, it is possible that its physiological relevance is marginal, for instance, in terms of within-cycle variations in lung perfusion; (4) two groups of subjects with considerably different levels of RSA showed similar redistribution of heartbeats, suggesting that this phenomenon might be an underlying effect of the overall cardio-respiratory interactions, and not directly of RSA

      Diagnosis of Arrhythmogenic CardioMyopathy (ACM) is challenging and often late after disease onset. No circulating biomarkers are available to date. Given their involvement in several cardiovascular diseases, plasma microRNAs warranted investigation as potential non-invasive diagnostic tools in ACM. We sought to identify circulating microRNAs differentially expressed in ACM with respect to Healthy Controls (HC) and Idiopathic Ventricular Tachycardia patients (IVT), often in differential diagnosis. ACM and HC subjects were screened for plasmatic expression of 377 microRNAs and validation was performed in 36 ACM, 53 HC, 21 IVT. Variable importance in data partition was estimated through Random Forest analysis and accuracy by Receiver Operating Curves. Plasmatic miR-320a showed 0.53 ± 0.04 fold expression difference in ACM vs. HC (p ACM (n = 13) and HC (n = 17) with athletic lifestyle, a ACM precipitating factor. Importantly, ACM patients miR-320a showed 0.78 ± 0.05 fold expression change vs. IVT (p = 0.03). When compared to non-invasive ACM diagnostic parameters, miR-320a ranked highly in discriminating ACM vs. IVT and it increased their accuracy. Finally, miR-320a expression did not correlate with ACM severity. Our data suggest that miR-320a may be considered a novel potential biomarker of ACM, specifically useful in ACM vs. IVT differentiation.

      Full Text Available The cardio-ankle vascular index (CAVI is used to test vascular function and is an arterial stiffness marker and potential predictor of cardiovascular events. This study aimed to analyze the relation between objective indices of diabetic polyneuropathy (DPN and the CAVI. One hundred sixty-six patients with type 2 diabetes mellitus were included in this study. We used nerve conduction studies (NCSs and the coefficient of variation of the R-R interval to evaluate DPN. We estimated arteriosclerosis by the CAVI. Simple and multiple linear regression analyses were performed between neuropathy indices and the CAVI. In univariate analysis, the CAVI showed significant associations with sural sensory nerve conduction velocity and median F-wave conduction velocity. Multiple linear regression analysis for the CAVI showed that sural nerve conduction velocity and median F-wave conduction velocity were significant explanatory variables second only to age. In multiple linear regression analysis for sural nerve conduction velocity among neuropathy indices, the CAVI remained the most significant explanatory variable. In multiple linear regression analysis for median nerve F-wave conduction velocity among neuropathy indices, the CAVI remained the second most significant explanatory variable following HbA1c. These results suggest a close relationship between macroangiopathy and DPN.

      The specific sodium-glucose cotransporter 2 inhibitors (SGLT2 inhibitors) inhibit glucose reabsorption in proximal renal tubular cells, and both fasting and postprandial glucose significantly decrease because of urinary glucose loss. As a result, pancreatic β-cell function and peripheral insulin action significantly improve with relief from glucose toxicity. Furthermore, whole-body energy metabolism changes to relative glucose deficiency and triggers increased lipolysis in fat cells, and fatty acid oxidation and then ketone body production in the liver during treatment with SGLT2 inhibitors. In addition, SGLT2 inhibitors have profound hemodynamic effects including diuresis, dehydration, weight loss and lowering blood pressure. The most recent findings on SGLT2 inhibitors come from results of the Empagliflozin, Cardiovascular Outcomes and Mortality in Type 2 Diabetes trial. SGLT2 inhibitors exert extremely unique and cardio-renal protection through metabolic and hemodynamic effects, with long-term durability on the reduction of blood glucose, bodyweight and blood pressure. Although a site of action of SGLT2 inhibitors is highly specific to inhibit renal glucose reabsorption, whole-body energy metabolism, and hemodynamic and renal functions are profoundly modulated during the treatment of SGLT2 inhibitors. Previous studies suggest multifactorial clinical benefits and safety concerns of SGLT2 inhibitors. Although ambivalent clinical results of this drug are still under active discussion, the present review summarizes promising recent evidence on the cardio-renal and metabolic benefits of SGLT2 inhibitors in the treatment of type 2 diabetes. © 2017 The Authors.

      n-3PUFA consumption has been widely accepted as a nutritional strategy for the secondary prevention of cardiovascular events in patients at high risk of cardiovascular disease (CVD), but little is known about the dose-response relationship between dietary n-3PUFA and serum biomarkers associated with cardiovascular health in the general population. The present study involved a 12-week double-blind, randomized controlled trial to explore the effects of fish oil with different doses (0.31, 0.62 and 1.24 g d-1 of EPA and DHA) on serum fatty acids and cardio-metabolic biomarkers including adiponectin, inflammatory markers, lipid profiles and fasting glucose in healthy middle-aged and elderly Chinese people. 240 volunteers met our inclusion criteria. A total of 39 subjects dropped out and 201 finally completed the intervention. No significant differences in baseline characteristics and daily intakes of dietary nutrients were detected among all groups. After a 12-week intervention, fish oil dose-dependently enhanced serum EPA, DHA, n-3PUFA and adiponectin (except for 0.31 g d-1), but decreased serum n-6/n-3PUFA, TG and fasting glucose. Changes in the above indicators from the baseline to week 12 in fish oil groups significantly differed from those in the control. Meanwhile, all the doses of EPA and DHA led to decreases in serum CRP; only 1.24 g d-1 led to an increase in HDL-C with a concurrent decrease in TC/HDL-C even though these changes were not significantly different among all groups. All the findings suggested that fish oil dose-dependently regulated serum PUFA and cardio-metabolic biomarkers including adiponectin, CRP, lipid profiles and fasting glucose in healthy middle-aged and elderly Chinese people who consumed insufficient dietary n-3PUFA, and the most desirable changes were observed for 1.24 g d-1.

      Lipoprotein-A (LpA) is an emerging independent risk factor for cerebro- and cardio-vascular diseases (CCVD). Recognizing its function and its normal distribution is of fundamental importance for a better understanding of CCVD patho-physiology. The present study evaluated plasma LpA levels of healthy university students using turbidimetric methods. Medians and inter-quartile differences obtained for male and female participants were 11.3mg/dL (3.1-30.7) and 20.9mg/dL (6.5-42.3), respectively, demonstrating a significant difference (P=0.017) between men and women. A third of students showed plasma concentrations above reference values. Our results indicate that 33% of students possess a hidden independent risk factor for CCVD. Multi-disciplinary evaluation and characterization of young individuals should be recommended in an attempt to take early preventive measures and to eliminate possible modifiable risk factors such as sedentary lifestyle, smoking, hypertension, obesity and atherogenic diet.

      Wireless monitoring of pulmonary artery (PA) pressures with the CardioMEMS HF™ system is indicated in patients with New York Heart Association (NYHA) class III heart failure (HF). Randomized and observational trials have shown a reduction in HF-related hospitalizations and improved quality of life in patients using this device in the United States. MEMS-HF is a prospective, non-randomized, open-label, multicenter study to characterize safety and feasibility of using remote PA pressure monitoring in a real-world setting in Germany, The Netherlands and Ireland. After informed consent, adult patients with NYHA class III HF and a recent HF-related hospitalization are evaluated for suitability for permanent implantation of a CardioMEMS™ sensor. Participation in MEMS-HF is open to qualifying subjects regardless of left ventricular ejection fraction (LVEF). Patients with reduced ejection fraction must be on stable guideline-directed pharmacotherapy as tolerated. The study will enroll 230 patients in approximately 35 centers. Expected duration is 36 months (24-month enrolment plus ≥ 12-month follow-up). Primary endpoints are freedom from device/system-related complications and freedom from pressure sensor failure at 12-month post-implant. Secondary endpoints include the annualized rate of HF-related hospitalization at 12 months versus the rate over the 12 months preceding implant, and health-related quality of life. Endpoints will be evaluated using data obtained after each subject's 12-month visit. The MEMS-HF study will provide robust evidence on the clinical safety and feasibility of implementing haemodynamic monitoring as a novel disease management tool in routine out-patient care in selected European healthcare systems.

      The aim of this study was to evaluate the efficiency of a short-term Intermittent Work Exercise Program (IWEP) among healthy elderly subjects. This longitudinal prospective study took place at the Strasbourg University Hospital geriatric department. One hundred and fifty older volunteers, previously determined as being free from cardiac and pulmonary disease, were separated into two age groups: the "young senior" (60.2 ± 3.1 yr) and the "older senior" groups (70.8 ± 5.2 yr). These groups were then subdivided by gender into the "young female senior", "young male senior" "older female senior" and "older male senior" groups. Before and after the IWEP, all subjects were asked to perform an incremental cycle exercise to obtain their first ventilatory threshold (VT1), maximal tolerated power (MTP), peak oxygen uptake (VO2peak) and maximal minute ventilation (MMV). The IWEP consisted of a 30-min cycling exercise which took place twice a week, and was divided into six 5-min stages consisting of 4 min at VT1 intensity and 1 min at 90% MTP. An assessment was made of the effects of the IWEP on maximal cardio-respiratory function (MTP, VO2peak, MMV) and endurance parameters (VT1, heart rate [HR] measured at pretraining VT1 and lactate concentrations at pre-training MTP). This short-term training program resulted in a significant increase of MTP (from 13.2% to 20.6%), VO2peak (from 8.9% to 16.6%) and MMV (from 11.1% to 21.8%) in all groups (pseniors" were not significantly different (p>0.05) from the "young seniors" pre-training values for the same parameters. The most striking finding in this study is that after only 9 weeks, our short-term "individually-tailored" IWEP significantly improved both maximal cardio-respiratory function and endurance parameters in healthy, previously untrained seniors.

      2018-03-01

      Renal involvement in some forms of acute or chronic diseases, such as heart failure or sepsis, presents with a complex pathophysiological basis that is not always clearly distinguishable. In these clinical settings, kidney failure is traditionally and almost exclusively attributed to renal hypoperfusion and it is commonly accepted that causal elements are pre-renal, such as a reduction in the ejection fraction or absolute or relative hypovolemia acting directly on oxygen transport mechanisms and renal autoregulation systems, causing a reduction of glomerular filtration rate. Nevertheless, the concept emerging from accumulating clinical and experimental evidence is that in complex clinical pictures, kidney failure is strongly linked to the hemodynamic alterations occurring in the renal venous micro and macrocirculation. Accordingly, the transmission of the increased venous pressure to the renal venous compartment and the consequent increasing renal afterload has a pivotal role in determining and sustaining the kidney damage. The aim of this review was to clarify the physiopathological aspects of the link between worsening renal function and renal venous hypertension, analyzing the prognostic and therapeutic implications of the so-called congestive kidney failure in cardio-renal syndrome and in other clinical contexts of its possible onset.

      A systematic review and meta-analysis of the literature was performed to assess the relationship between chocolate intake and cardio-cerebrovascular risk in the general population. A structured search of the literature was performed in the PubMed database up to September 26, 2016, using predetermined keywords. Epidemiologic studies evaluating the risk for cardiovascular diseases (CVDs; i.e., stroke, acute myocardial infarction [MI], heart failure, coronary heart disease) were included according to different rates of chocolate intake. The software ProMeta 3 was used to perform the meta-analysis. The systematic review identified 16 eligible studies. The majority of the studies showed a protective effect of chocolate intake compared with unexposed individuals. The overall risk ratio (effect size [ES]) of CVD for the highest versus the lowest category of chocolate consumption was 0.77 (95% confidence interval [CI], 0.71-0.84; P = 0.000) with a moderate heterogeneity. The risk related to subgroups of CVD and in particular, the risk for MI was further analyzed: ES = 0.78 (95% CI, 0.64-0.94; P = 0.009) without statistical heterogeneity (I 2  = 46.56%; P = 0.13). Moreover, the analysis performed based on sex found an ES = 0.85 (95% CI, 0.77-0.95; P = 0.003) for women, with a very low grade of heterogeneity (I 2  = 62.21%; P = 0.005). The results of the meta-analysis showed a potential protective effect of moderate consumption of chocolate on cardiovascular risk, especially for women, and against MI for both sexes.

      Noonan syndrome (NS) and cardio-facio-cutaneous syndrome (CFCS) are related developmental disorders caused by mutations in genes encoding various components of the RAS-MAPK signaling cascade. NS is associated with mutations in the genes PTPN11, SOS1, RAF1, or KRAS, whereas CFCS can be caused by mutations in BRAF, MEK1, MEK2, or KRAS. The NS phenotype is rarely accompanied by multiple giant cell lesions (MGCL) of the jaw (Noonan-like/MGCL syndrome (NL/MGCLS)). PTPN11 mutations are the only genetic abnormalities reported so far in some patients with NL/MGCLS and in one individual with LEOPARD syndrome and MGCL. In a cohort of 75 NS patients previously tested negative for mutations in PTPN11 and KRAS, we detected SOS1 mutations in 11 individuals, four of whom had MGCL. To explore further the relevance of aberrant RAS-MAPK signaling in syndromic MGCL, we analyzed the established genes causing CFCS in three subjects with MGCL associated with a phenotype fitting CFCS. Mutations in BRAF or MEK1 were identified in these patients. All mutations detected in these seven patients with syndromic MGCL had previously been described in NS or CFCS without apparent MGCL. This study demonstrates that MGCL may occur in NS and CFCS with various underlying genetic alterations and no obvious genotype–phenotype correlation. This suggests that dysregulation of the RAS-MAPK pathway represents the common and basic molecular event predisposing to giant cell lesion formation in patients with NS and CFCS rather than specific mutation effects.

      Approximately 5% of children with neural tube defects (NTDs) have a congenital heart defect and/or cleft lip and palate. The cause of isolated meningomyelocele, congenital heart defects, or cleft lip and palate has been largely thought to be multifactorial. However, chromosomal, teratogenic, and single gene causes of combinations of NTDs with congenital heart defects and/or cleft lip and palate have been reported. We report on 3 patients with meningomyelocele, congenital heart defects, and 22q11 deletions. Two of the children had the clinical diagnosis of velo-cardio-facial syndrome (VCFS); both have bifid uvula. The third child had DiGeorge sequence (DGS). The association of NTDs with 22q11 deletion has not been reported previously. An accurate diagnosis of the 22q11 deletion is critical as this micro-deletion and its associated clinical problems is transmitted as an autosomal dominant trait due to the inheritance of the deletion-bearing chromosome. We recommend that all children with NTDs and congenital heart defects, with or without cleft palate, have cytogenetic and molecular studies performed to detect 22q11 deletions. 31 refs., 3 figs.

      Transform was applied to decompose the representative signals on a time-scale basis in a frequency region of [0.01 - 0.1] Hz. Their linear coupling was quantified through a coherence metric and the synchrony was characterised via the phase information to determine regions where pairs of signals were in phase lock and thereby inferring an interaction or coupling. From these data we investigate the percent time in each of two coupled interactions: EMG-SBP and COP-SBP. RESULTS: The time percentages from EMG-SBP was 6.2% (baseline), 8.1% (pre-stand), 7.7% (1g), 13.6% (2g), 10.8% (post-stand), and 8.2 (recovery-stand).ANOVA comparison (EMG-SBP) among baseline supine (6.2%), 1g (7.7%), and 2g (13.6%) yielded a p value of 0.04. Student-Newman-Keuls post hoc test showed that 2g is significantly higher than supine1 (p=0.04) and marginal significant difference between 1g and 2g (p=0.052). There was no effect of centrifugation on stand EMG-SBP, but COP-SBP was marginally increased in the recovery stand (pre-stand: 10.5%; post-stand 8.9%; recovery-stand 15.7%, p=0.20). CONCLUSION: These data indicated the activation of cardio-postural control system throughout stand and supine centrifugation, with elevation of the recruitment of muscle pump at 2g.

      Full Text Available Epidemiological evidence indicates an inverse association between nut consumption and obesity, inflammation, hyperlipidaemia and glucose intolerance. We investigated effects of high oleic peanut consumption vs. a nut free diet on adiposity and cardio-metabolic risk markers. In a randomised cross-over design, 61 healthy subjects (65 ± 7 years, body mass index (BMI 31 ± 4 kg/m2 alternated either high oleic peanuts (15%–20% of energy or a nut free diet for 12 weeks. Body composition and mass, waist circumference, C-reactive protein (CRP, lipids, glucose and insulin were assessed at baseline and after each phase. Repeated measures analysis of variance (ANOVA compared the two diets. Consistent with other nut studies, there were no differences in lipids, CRP, glucose and insulin with peanut consumption. In contrast, some reports have demonstrated benefits, likely due to differences in the study cohort. Energy intake was 10% higher (853 kJ, p < 0.05, following peanut consumption vs. control, attributed to a 30% increase in fat intake (p < 0.001, predominantly monounsaturated (increase 22 g, p < 0.05.

      This study aimed to examine whether cardiorespiratory fitness (CRF) is associated with arterial stiffening, evaluated using the cardio-ankle vascular index (CAVI), independent of visceral fat (VF) in middle-aged and elderly Japanese men. We also examined whether the relationship between CRF and the CAVI is modified by age and/or hypertension. The CAVI was determined in 157 Japanese men (age range, 30-79 years), including 96 hypertensive subjects (61.1%). CRF was assessed by measuring the peak oxygen uptake (VO2peak). The subjects were divided into low- and high-CRF groups, and the VF area was assessed using magnetic resonance imaging. The VO2peak correlated with the CAVI following adjustment for age and body mass index in the middle-aged and elderly groups (all the subjects: r=-0.285, p<0.001; middle-aged: r=-0.240, p=0.040; elderly: r=-0.225, p=0.049).

      Genetic disorders that disrupt the structure and function of the cardiovascular system and the peripheral nervous system are common enough to be encountered in routine cardiovascular practice. Although often these patients are diagnosed in childhood and come to the cardiologist fully characterized, some patients with hereditary neuromuscular disease may not manifest until adulthood and will present initially to the adult cardiologist for an evaluation of an abnormal ECG, unexplained syncope, LV hypertrophy, and or a dilated cardiomyopathy of unknown cause. Cardiologists are often ill-equipped to manage these patients due to lack of training and exposure as well as the complete absence of practice guidelines to aid in the diagnosis and management of these disorders. Here, we review three key neuromuscular diseases that affect the cardiovascular system in adults (myotonic dystrophy type 1, Friedreich ataxia, and Emery-Dreifuss muscular dystrophy), with an emphasis on their clinical presentation, genetic and molecular pathogenesis, and recent important research on medical and interventional treatments. We also advocate the development of interdisciplinary cardio-neuromuscular clinics to optimize the care for these patients. Copyright © 2016 Elsevier Inc. All rights reserved.

    13. Association of codon 108/158 catechol-O-methyltransferase gene polymorphism with the psychiatric manifestations of velo-cardio-facial syndrome

      Velo-cardio-facial-syndrome (VCFS) is a common congenital disorder associated with typical facial appearance, cleft palate, cardiac defects, and learning disabilities. The majority of patients have an interstitial deletion on chromosome 22q11. In addition to physical abnormalities, a variety of psychiatric illnesses have been reported in patients with VCFS, including schizophrenia, bipolar disorder, and attention deficit hyperactivity disorder. The psychiatric manifestations of VCFS could be due to haploinsufficiency of a gene(s) within 22q11. One candidate that has been mapped to this region is catechol-O-methyltransferase (COMT). We recently identified a polymorphism in the COMT gene that leads to a valine{r_arrow}methionine substitution at amino acid 158 of the membrane-bound form of the enzyme. Homozygosity for COMT158{sup met} leads to a 3- to 4-fold reduction in enzymatic activity, compared with homozygotes for COMT158{sup met}. We now report that in a population of patients with VCFS, there is an apparent association between the low-activity allele, COMT158{sup met}, and the development of bipolar spectrum disorder, and in particular, a rapid-cycling form. 33 refs., 3 tabs.

      Full Text Available The Daniel Fast is a biblically inspired dietary program rich in carbohydrate, most closely resembling a vegan diet but with additional restrictions, including the elimination of processed foods, white flour products, preservatives, additives, sweeteners, caffeine, and alcohol. While no specific requirements are placed on the ingestion of specific percentages of macronutrients, the mean daily carbohydrate intake is by default approximately 60%, while protein and fat intake are 15% and 25%, respectively. Despite a relatively high carbohydrate intake, multiple favorable cardio-metabolic effects are noted when following the plan, in as few as three weeks. This includes improvements in HOMA-IR, which may be at least in part due to the lower glycemic load and high dietary fiber content of the foods consumed. Other notable changes include reductions in systemic inflammation, total and LDL-cholesterol, oxidative stress, blood pressure, and body weight/body fat. Short and moderate-term compliance to the program is excellent-better than most dietary programs, perhaps due to the ad libitum nature of this plan. This paper presents an overview of the Daniel Fast, a carbohydrate-rich dietary program, including relevant findings from both human and animal investigations using this dietary model.

      Con la finalidad de comprobar los efectos retardantes del calcio en la maduración de los frutos de feijoa (Acca sellowiana Berg, cultivar Quimba, se realizó un estudio sobre la aplicación poscosecha, mediante inmersiones de tres soluciones distintas de cloruro de calcio (5%, 10% y 15% y un testigo. La aplicación de CaCl2 prolongó la vida de almacenamiento de los fru­tos, ya que los tratamientos permitieron a los frutos so­portar las condiciones de almacenamiento. Se observó un efecto importante en la disminución de las pérdidas de peso; los frutos tratados con el porcentaje de calcio más alto (15% presentaron las menores pérdidas de peso en cada temperatura. En las fejioas almacenadas a temperatura ambiente (18° C, se observó que la in­cidencia de enfermedades fue más pequeña en los fru­tos tratados con CaCl2. La velocidad de pérdida de la firmeza de los frutos también se vio fortalecida por la adición de calcio. Con relación a las propiedades quí­micas de los frutos, no se presentaron diferencias sig­nificativas entre los tratamientos con cloruro de calcio para cada temperatura de almacenamiento; las feijoas tratadas con CaCl presentaron niveles superiores de sólidos solubles totales, a pesar de no ser significativos estadísticamente.

      Full Text Available Background: Stress and anxiety have become an integral part of our lives. Of late, this has resulted in the increase in incidence of hypertension and coronary heart disease. Objectives: To assess the effect of progressive muscle relaxation (PMR on young adult males and its role in the modulation of cardio-respiratory response on exposure to stress. Materials and Methods: This prospective cross-sectional study was conducted in a tertiary care referral hospital. Undergraduate male students under stress were chosen for the study. Fasting blood samples were drawn to analyze sugar and lipid profile, followed by anthropometric measurements and ECG. In the resting condition, blood pressure, pulse rate, and spirometric parameters; forced vital capacities (FVC, and forced expiratory volume in 1 sec (FEV 1 % were measured. Then, they were made to exercise with bicycle ergometer and post exercise, the vital parameters were recorded. All subjects were given a training of Jacobson′s Progressive Muscular Relaxation and asked to practice this technique for 3 months. All parameters were re-evaluated. Results: Significant decreases in resting heart rate, systolic blood pressure and diastolic blood pressure, total cholesterol, triglyceride, and low density lipoprotein (LDL cholesterol levels of subjects were seen after PMR training. Exercise-induced rise in heart rate and blood pressure were also significantly less in subjects following PMR training. Conclusion: Progressive muscle relaxation helps in modulation of heart rate, blood pressure, and lipid profile in healthy normal adult male individuals.

A hipertermia severa induzida pelo esforço físico (HTE prejudica a saúde e está associada à morbidade e mortalidade de indivíduos em diferentes atividades ocupacionais e atléticas. Estudos sobre a eficiência de métodos de resfriamento corporal têm recomendado a imersão em água fria para o tratamento da HTE. Sua utilização nos minutos iniciais pós-hipertemia parece a melhor recomendação por reduzir o tempo no qual a temperatura central permanece elevada. A manutenção de infraestrutura necessária para a realização desse procedimento deve ser considerada em atividades físicas e condições ambientais nas quais os indivíduos estão mais suscetíveis ao acometimento da HTE. As taxas de resfriamento observadas através da imersão em água a diferentes temperaturas podem servir de referência para o controle da duração do procedimento. Esta revisão analisa a recomendação da imersão em água fria como procedimento de resfriamento corporal para o manejo da HTE.The incapacity of dissipating heat generated by muscular activity hampers performance and increases predisposition to physical injuries. Exertional heat illness (HTE harms health and is associated with morbidity and mortality of individuals in different occupational and athletic activities.

Its use in the initial minutes of post-hyperthermia seems to be the best recommendation to reduce the time central temperature remains high. Maintenance of the infrastructure needed to perform this procedure should be considered in physical activities and environmental conditions in which the individuals are more prone to HTE.

      This paper presents a summary of the potential practical and economic barriers to implementation of primary prevention of cardiovascular disease guided by total cardiovascular risk estimations in the general population. It also reviews various possible solutions to overcome these barriers. The report is based on discussion among experts in the area at a special CardioVascular Clinical Trialists workshop organized by the European Society of Cardiology Working Group on Cardiovascular Pharmacology and Drug Therapy that took place in September 2009. It includes a review of the evidence in favour of the \\'treat-to-target\\' paradigm, as well as potential difficulties with this approach, including the multiple pathological processes present in high-risk patients that may not be adequately addressed by this strategy. The risk-guided therapy approach requires careful definitions of cardiovascular risk and consideration of clinical endpoints as well as the differences between trial and \\'real-world\\' populations. Cost-effectiveness presents another issue in scenarios of finite healthcare resources, as does the difficulty of documenting guideline uptake and effectiveness in the primary care setting, where early modification of risk factors may be more beneficial than later attempts to manage established disease. The key to guideline implementation is to improve the quality of risk assessment and demonstrate the association between risk factors, intervention, and reduced event rates. In the future, this may be made possible by means of automated data entry and various other measures. In conclusion, opportunities exist to increase guideline implementation in the primary care setting, with potential benefits for both the general population and healthcare resources.

      Prematurity at birth is a known risk factor for the development of an early chronic renal disease. Urinary neutrophil gelatinase-associated lipocalin (NGAL) is a well established biomarker of kidney injury, while high blood levels of asymmetric dimethylarginine (ADMA) are associated with the future development of adverse cardiovascular events and cardiac death. (1) to verify the presence of statistically significant differences between urinary NGAL and hematic ADMA levels in young adults born preterm at extremely low birth weight (<1000 g; ex-ELBW) and those of a control group of healthy adults born at term (C) (2) to seek correlations between NGAL and ADMA levels, which would indicate the presence of an early cardio-renal involvement in ex-ELBW. Twelve ex-ELBW subjects (six males and six female, mean age: 23.9 ± 3.2 years) were compared with 12 C (six males and six female). Urinary NGAL and hematic ADMA levels were assessed. Urinary NGAL levels were higher in ex- ELBW subjects compared to C (p < 0.05), as well as hematic ADMA concentrations (p < 0.05). A statistically significant correlation was found between urinary NGAL and ADMA (r = -0.60, p < 0.04). Our preliminary findings support the hypothesis that in ex-ELBW subjects the development of an early chronic kidney disease contributes towards inducing an increase in the atherosclerotic process and in the risk of future adverse cardiovascular events.

      Pulmonary edema is a consistent feature of Mesobuthus tamulus (MBT) envenomation. Kinins, prostaglandins and other inflammatory mediators are implicated in it. Since, histamine also increases capillary permeability, this study was undertaken to evaluate whether MBT venom utilizes histamine to produce pulmonary edema and augmentation of cardio-respiratory reflexes evoked by phenylbiguanide (PBG). Blood pressure, respiratory excursions and ECG were recorded in urethane anaesthetized adult rats. Injection of PBG (10 μg/kg) produced apnoea, hypotension and bradycardia and the responses were augmented after exposure to venom (100 μg/kg). There was increased pulmonary water content in these animals. Pretreatment with pheniramine maleate (H₁ antagonist, 3 mg/kg) blocked both venom-induced augmentation of PBG response and pulmonary edema. In another series, compound 48/80 (mast cell depletor) was treated for 4 days then the PBG responses were elicited as before. At the end of the experiments, mast cells were counted from the peritoneal fluid. The venom-induced pulmonary edema and the augmentation of PBG reflex were not observed in compound 48/80 treated animals. Further, mast cells in the peritoneal fluid were absent in this group as compared to vehicle treated group (29 ± 7.9 cells/mm³). These observations indicate that venom-induced pulmonary edema and augmentation of PBG reflexe are mediated through mast cells by involving H₁ receptors. Copyright © 2010 Elsevier Ltd.

      Full Text Available Se realizó una investigación descriptiva-prospectiva con el objetivo de validar nuestros criterios de riesgos en la identificación de la infección bacteriana severa (IBS en niños febriles, para lo cual se establecieron las categorías de riesgos y se aplicaron en 215 niños febriles que habían ingresado por esta causa en un período de 12 meses. Se obtuvo que el 54,9 % de los niños se clasificaron como bajo riesgo y el 71,6 % sin IBS. No obstante, la frecuencia de dicha afección resultó elevada, 28,4 %, con predominio de las infecciones urinarias. Se triplicó el riesgo de padecer IBS en los niños con aspecto tóxico, temperatura mayor o igual a 39°C, test clínico de Bonadio mayor que 8, cituria mayor o igual a 10 000 células/mm³, con diferencias significativas entre las categorías de riesgo y la IBS, y fue mayor la frecuencia en los niños tóxicos y de riesgos, 92,8 y 54,3 %, respectivamente. Uno de cada 4 niños febriles presentó IBS. Se introdujo la categoría "Riesgo" y se recomienda un flujograma de evaluación.A descriptive-prospective research study was carried out to validate our risk criteria in the identification of severe bacterial infection in febrile young children. For this purpose, risk categories were set and applied in 215 febrile children who had been admitted in a period of 12 months. 54.9 % of febrile children were at low risk for serious bacterial infections whereas 71.6 % presented no risk at all. Nevertheless, the frequency of this affection was high, accounting for 28.4 % with predominance of urinary infections. The risk of getting SBI trippled in children who shared toxic look, temperature greater than or equal to 39 °C, Bonadium clinical test higher than 8, cyturia values over or equal to 10 000 cell/mm³, significant differences between risk and SBI categories and the highest frequency of such affection found in toxic children and in children at low risk (92.8 vs 54.3 %.

      Full Text Available La Solución CM-95 tratada magnéticamente es un producto en desarrollo que mostró propiedades inmunoestimulantes en ensayos preclínicos, característica que la hacen adecuada como candidata a inmunopotenciador. En este trabajo se evaluaron los posibles efectos tóxicos preclínicos de la Solución CM-95 tratada magnéticamente, por el método de las Clases de Toxicidad Aguda y el de irritación de la mucosa oral, adaptando las normas OECD 423 y la ISO 10993-10, respectivamente. En el método de las Clases de Toxicidad Aguda se utilizó el ensayo límite, en ratas Sprague Dawley hembras, en el cual la dosis estuvo relacionada con el nivel de inducción magnética, en este caso 0,16 T, aplicado a la Solución CM-95; y el volumen a administrar de la misma, calculado sobre la base de 2 ml de la solución por 100 g de peso corporal. La determinación de la irritación de la mucosa oral se llevó a cabo en hámster Sirios Dorados hembras mediante un ensayo a dosis repetidas durante 7 días de tratamiento en la bolsa gular derecha, con pellet de algodón impregnado con 0,5 ml de la solución tratada magnéticamente con la misma inducción. No se encontró mortalidad ni evidencias de signos tóxicos para el ensayo de toxicidad aguda, y se obtuvo un índice de irritación sobre mucosa oral de 0, por lo que la sustancia estudiada se enmarcó como "No clasificada" y "No irritante" según la metodología empleada. Estos resultados complementarán otros estudios toxicológicos para avalar la seguridad de esta Solución para su uso futuro como fármaco por vía oral.CM-95 solution magnetically treated is a product which showed immunologic properties in preliminary tests, characteristic that makes it adequate as inmunopotentiator candidate. In this study the possible preclinical toxic effects of CM-95 Solution magnetically treated were evaluated, by the Acute Toxicity Class method and oral mucosa irritation test, adapting guideline OECD 423 and ISO 10993

      Full Text Available La escoliosis es una deformidad de la columna que se presenta como una curva estructural que determina un grado variable de deformidad del tronco. La forma más común es la escoliosis idiopática del adolescente, que se desarrolla en la columna, en la fase de crecimiento y puede tener importantes efectos cosméticos y funcionales, pero es siempre un diagnóstico de exclusión. La escoliosis puede ser tratada con observación seriada, uso de ortesis o cirugía, según su magnitud y potencial evolución de severidad. Sin embargo, el comportamiento de la curva es frecuentemente difícil de predecir durante el desarrollo, por lo que el seguimiento clínico y radiológico seriado es clave en la decisión de tratamiento. Aparte de la cirugía, sólo el tratamiento con corset puede frenar la progresión de una curva, si bien no corregirla. Las curvas severas o que progresen dentro del corset tienen indicación de corrección y fusión quirúrgica. Las curvas noidiopáticas se comportan en forma diferente y su manejo es también distinto. El objetivo de este artículo es presentar los aspectos clave de la evaluación inicial de un paciente con escoliosis y entregar una visión actualizada del tratamiento de las distintas formas de presentación de esta afección.

      Evidence that home telemonitoring for patients with chronic heart failure (CHF) offers clinical benefit over usual care is controversial as is evidence of a health economic advantage. Between January 2010 and June 2013, patients with a confirmed diagnosis of CHF were enrolled and randomly assigned to 2 study groups comprising usual care with and without an interactive bi-directional remote monitoring system (Motiva®). The primary endpoint in CardioBBEAT is the Incremental Cost-Effectiveness Ratio (ICER) established by the groups' difference in total cost and in the combined clinical endpoint "days alive and not in hospital nor inpatient care per potential days in study" within the follow-up of 12 months. A total of 621 predominantly male patients were enrolled, whereof 302 patients were assigned to the intervention group and 319 to the control group. Ischemic cardiomyopathy was the leading cause of heart failure. Despite randomization, subjects of the control group were more often in NYHA functional class III-IV, and exhibited peripheral edema and renal dysfunction more often. Additionally, the control and intervention groups differed in heart rhythm disorders. No differences existed regarding risk factor profile, comorbidities, echocardiographic parameters, especially left ventricular and diastolic diameter and ejection fraction, as well as functional test results, medication and quality of life. While the observed baseline differences may well be a play of chance, they are of clinical relevance. Therefore, the statistical analysis plan was extended to include adjusted analyses with respect to the baseline imbalances. CardioBBEAT provides prospective outcome data on both, clinical and health economic impact of home telemonitoring in CHF. The study differs by the use of a high evidence level randomized controlled trial (RCT) design along with actual cost data obtained from health insurance companies. Its results are conducive to informed political and economic

      Full Text Available El objetivo principal del presente trabajo fue identificar las discrepancias clínico-patológicas en las autopsias realizadas en la institución. Se revisaron 53 autopsias de casos clínicos en adultos en el período comprendido entre enero de 2005 y junio de 2009, realizadas en el servicio de Anatomía Patológica del Hospital Privado de Córdoba, Argentina. Se excluyeron seis debido a información insuficiente. Se aplicó la clasificación de Goldman y col. para establecer las discrepancias clínico-patológicas entre los diagnósticos pre y post-mortem. Los diagnósticos clínicos más frecuentes fueron las infecciones respiratorias y el tromboembolismo pulmonar agudo. Los hallazgos de autopsia más frecuentes fueron las infecciones respiratorias y el infarto agudo de miocardio. Se detectaron 17 discrepancias mayores y 30 concordancias, no se detectaron discrepancias menores. Las infecciones respiratorias fueron la principal causa de error, seguidas por el infarto agudo de miocardio. Concluimos que en 17/47 (37% de los casos se realizó un diagnóstico clínico diferente al post-mortem, y que las infecciones respiratorias constituyen el principal tipo de error. Se sugiere adoptar estrategias informativas y educativas, revalorizar la autopsia y las prácticas clínicas tradicionales.

      Full Text Available OBJETIVO: Fornecer informações para auxiliar o médico pediatra a reconhecer os fatores de risco para o início da cárie precoce na infância e da cárie severa na infância (CSI, possibilitando a intervenção precoce de tais fatores, e, assim, evitar a instalação dessa doença prevenível e as suas consequências. FONTES DOS DADOS: As informações foram coletadas a partir de artigos científicos publicados nas bases de dados SciELO, MEDLINE e PUBMED nos últimos 25 anos, livros técnicos e publicações de consenso de organismos internacionais. As palavras-chave utilizadas foram: early childhood caries, severe early childhood caries, dental caries e children. SÍNTESE DOS DADOS: A CSI é uma forma de cárie dentária que afeta bebês e crianças. É infecciosa, de etiologia multifatorial e de desenvolvimento rápido, iniciando logo após a erupção dos dentes. Por apresentar fatores de risco local e sociocultural, deve ser considerada como sintoma de uma alteração na criança e de falta de cuidados adequados. Suas manifestações incluem dor, abscessos e dificuldades mastigatórias, afetando a alimentação e o sono da criança. Além disso, afeta também sua saúde geral, fala e autoestima. CONCLUSÕES: A CSI é uma doença com métodos preventivos estabelecidos, que devem ser introduzidos o mais precocemente possível, por meio de programas preventivos na comunidade e no núcleo familiar. Os profissionais que atendem bebês e crianças devem estar atentos aos casos com risco para o desenvolvimento da doença cárie e interceder a fim de se obter saúde.OBJECTIVE: To provide information with the purpose of helping pediatricians to recognize the risk factors for the onset of severe early childhood caries, allowing for early intervention and thus avoiding this preventable disease and its consequences.
