    Full Text Available The majority of all deaths attributable to cardiovascular diseases (CVDs are in developing countries. There is now a pressing need for developing countries to define and implement preventive interventions for CVDs. We used WHO MONICA Project protocols to measure trends in coronary risk factors in Bushehr Port in the Persian Gulf Healthy Heart Project. Coronary risk factors of 2092 , aged >= 25 years men and women were evaluated in a cross-sectional study. Of the studied population, 97.7% had at least one coronary risk factor, 44.3% of men and 69% of women had at least two coronary risk factors. The high prevalence rates of diabetes mellitus (8.6%, central obesity (59.4%, obesity (26.8%, hypertension (24.5%, smoking (15.7%, physical inactivity (71.1%, hypercholesterolemia (24% and low HDL-cholesterol (61.5% showed that coronary risk factors prevail in Bushehr Port. Therefore, preventive strategies should be implemented immediately to avoid cardiovascular epidemic in the near future.

    Several published diabetes prediction models include information about family history of diabetes. The aim of this study was to extend the previously developed German Diabetes Risk Score (GDRS) with family history of diabetes and to validate the updated GDRS in the Multinational MONItoring of trends and determinants in CArdiovascular Diseases (MONICA)/German Cooperative Health Research in the Region of Augsburg (KORA) study. We used data from the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam study for extending the GDRS, including 21,846 participants. Within 5 years of follow-up 492 participants developed diabetes. The definition of family history included information about the father, the mother and/or sibling/s. Model extension was evaluated by discrimination and reclassification. We updated the calculation of the score and absolute risks. External validation was performed in the MONICA/KORA study comprising 11,940 participants with 315 incident cases after 5 years of follow-up. The basic ROC-AUC of 0.856 (95%-CI: 0.842-0.870) was improved by 0.007 (0.003-0.011) when parent and sibling history was included in the GDRS. The net reclassification improvement was 0.110 (0.072-0.149), respectively. For the updated score we demonstrated good calibration across all tenths of risk. In MONICA/KORA, the ROC-AUC was 0.837 (0.819-0.855); regarding calibration we saw slight overestimation of absolute risks. Inclusion of the number of diabetes-affected parents and sibling history improved the prediction of type 2 diabetes. Therefore, we updated the GDRS algorithm accordingly. Validation in another German cohort study showed good discrimination and acceptable calibration for the vast majority of individuals. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    1995-01-01

    Socio-economic status (SES) has been reported as a causative factor of increasing health inequalities in industrialized countries. The phenomenon has been particularly investigated for job related diseases, including cardiovascular disease and risk. The group of occupational medicine specialists in the world wide MONItoring program of CARdiovascular disease (WHO-MONICA Project) is now producing a number of hypotheses about the application of internationally defined criteria and tools for SES evaluation in the Italian area of the Project, Area Brianza. After a short review of some main conceptual and methodological problems, a proposal is presented of an SES index, derived from the pooled data of two population surveys carried out in this area. From a randomized sample of 3200 residents, 25-64 years old, stratified by sex and age decade, 1731 subjects, 594 females and 1137 males, employed at the time of the screening were extracted. Four variables were considered: age, education, occupational level and job-strain (according to the Karasek-Theorell model) by which each subject was classified in three levels--high, medium, low--of education and occupation, whose combination was used to obtain as many levels of socio-economic status. This a method of building an SES index is based on a sequence of approximations following two essential criteria: limitation of the variables to be surveyed, through standardized procedures; ability to identify the "low" SES category, presumably more at risk for disease.

  18. Does inclusion of education and marital status improve SCORE performance in central and eastern europe and former soviet union? findings from MONICA and HAPIEE cohorts.

    Directory of Open Access Journals (Sweden)

    Full Text Available The SCORE scale predicts the 10-year risk of fatal atherosclerotic cardiovascular disease (CVD, based on conventional risk factors. The high-risk version of SCORE is recommended for Central and Eastern Europe and former Soviet Union (CEE/FSU, due to high CVD mortality rates in these countries. Given the pronounced social gradient in cardiovascular mortality in the region, it is important to consider social factors in the CVD risk prediction. We investigated whether adding education and marital status to SCORE benefits its prognostic performance in two sets of population-based CEE/FSU cohorts.The WHO MONICA (MONItoring of trends and determinants in CArdiovascular disease cohorts from the Czech Republic, Poland (Warsaw and Tarnobrzeg, Lithuania (Kaunas, and Russia (Novosibirsk were followed from the mid-1980s (577 atherosclerotic CVD deaths among 14,969 participants with non-missing data. The HAPIEE (Health, Alcohol, and Psychosocial factors In Eastern Europe study follows Czech, Polish (Krakow, and Russian (Novosibirsk cohorts from 2002-05 (395 atherosclerotic CVD deaths in 19,900 individuals with non-missing data.In MONICA and HAPIEE, the high-risk SCORE ≥5% at baseline strongly and significantly predicted fatal CVD both before and after adjustment for education and marital status. After controlling for SCORE, lower education and non-married status were significantly associated with CVD mortality in some samples. SCORE extension by these additional risk factors only slightly improved indices of calibration and discrimination (integrated discrimination improvement <5% in men and ≤1% in women.Extending SCORE by education and marital status failed to substantially improve its prognostic performance in population-based CEE/FSU cohorts.

    Full Text Available Introducción: las creencias adictivas constituyen un riesgo para el uso de sustancias; contribuyen a mantener el consumo y proporcionan un trasfondo para la recaída. En la actualidad existen cuestionarios que miden creencias relacionadas con el consumo de sustancias de manera global, pero ninguno está enfocado en evaluar creencias adictivas en fumadores; hacerlo apoyaría en el manejo clínico de las personas que buscan dejar de fumar. Objetivo: evaluar la estructura factorial de un cuestionario que mide creencias adictivas en fumadores. Método: mediante un muestreo intencional se obtuvo una muestra de 300 jóvenes fumadores mayores de 18 años. Todos los participantes respondieron un cuestionario de autorreporte compuesto por 60 ítems que exploran creencias relacionadas con el consumo de tabaco. Se realizó un análisis factorial confirmatorio (AFC para determinar el modelo con un ajuste adecuado. Resultados: luego de evaluar dos modelos con AFC, se seleccionó uno de tres factores con una carga cruzada, cuyas medidas de bondad de ajuste fueron X2 S-B (22 = 38.37, p = .01, X2 S-B / gl = 1.74. CFIS = .978 RMSEAS = .050 (IC 90% .021–.076, que indican un ajuste adecuado de los datos. Discusión y conclusiones: la estructura factorial del CCAF está asociada con las creencias adictivas descritas por Beck.

  2. Geology of the continental margin beneath Santa Monica Bay, Southern California, from seismic-reflection data

    We interpret seismic-reflection data, which were collected in Santa Monica Bay using a 70-in3 generator-injector air gun, to show the geologic structure of the continental shelf and slope and of the deep-water, Santa Monica and San Pedro Basins. The goal of this research is to investigate the earthquake hazard posed to urban areas by offshore faults. These data reveal that northwest of the Palos Verdes Peninsula, the Palos Verdes Fault neither offsets the seafloor nor cuts through an undeformed sediment apron that postdates the last sea level rise. Other evidence indicates that this fault extends northwest beneath the shelf in the deep subsurface. However, other major faults in the study area, such as the Dume and San Pedro Basin Faults, were active recently, as indicated by an arched seafloor and offset shallow sediment. Rocks under the lower continental slope are deformed to differing degrees on opposite sides of Santa Monica Canyon. Northwest of this canyon, the continental slope is underlain by a little-deformed sediment apron; the main structures that deform this apron are two lower-slope anticlines that extend toward Point Dume and are cored by faults showing reverse or thrust separation. Southeast of Santa Monica Canyon, lower-slope rocks are deformed by a complex arrangement of strike-slip, normal, and reverse faults. The San Pedro Escarpment rises abruptly along the southeast side of Santa Monica Canyon. Reverse faults and folds underpinning this escarpment steepen progressively southeastward. Locally they form flower structures and cut downward into basement rocks. These faults merge downward with the San Pedro Basin fault zone, which is nearly vertical and strike slip. The escarpment and its attendant structures diverge from this strike-slip fault zone and extend for 60 km along the margin, separating the continental shelf from the deep-water basins. The deep-water Santa Monica Basin has large extent but is filled with only a thin (less than 1.5-km

    In the storage ring experiments at the PETRA accelerator, large cylindrical detectors with thousands of channels are used. The maximum event rate is 500 000 per second, i.e. effective preprocessing is required. In the TASSO detector this is achieved in two steps: A fast trigger system is able to make within 1 microsecond a decision, whether it is a useful event or not. A positive decision starts an on-line track-following ECL computer together with fast associative memories and table look-up. It is a microprogrammed on-line track analyzer called MONICA, which follows up to 10 tracks within 1 millisecond and calculates the coordinates in the R,phi-plane. CAMAC equipment is used for the input of raw data and the output of the calculated track coordinates, speed of the system is ensured by the computer. An outline of the algorithm used and the features of MONICA are given. As far as we know MONICA is the first running on-line track following free programmable microporcessor used in storage ring experiments. (orig.)

  6. Geomorphology, acoustic backscatter, and processes in Santa Monica Bay from multibeam mapping.

    2003-01-01

    Santa Monica Bay was mapped in 1996 using a high-resolution multibeam system, providing the first substantial update of the submarine geomorphology since the initial compilation by Shepard and Emery [(1941) Geol. Soc. Amer. Spec. Paper 31]. The multibeam mapping generated not only high-resolution bathymetry, but also coregistered, calibrated acoustic backscatter at 95 kHz. The geomorphology has been subdivided into six provinces; shelf, marginal plateau, submarine canyon, basin slope, apron, and basin. The dimensions, gradients, and backscatter characteristics of each province is described and related to a combination of tectonics, climate, sea level, and sediment supply. Fluctuations of eustatic sea level have had a profound effect on the area; by periodically eroding the surface of Santa Monica plateau, extending the mouth of the Los Angeles River to various locations along the shelf break, and by connecting submarine canyons to rivers. A wetter glacial climate undoubtedly generated more sediment to the rivers that then transported the increased sediment load to the low-stand coastline and canyon heads. The trends of Santa Monica Canyon and several bathymetric highs suggest a complex tectonic stress field that has controlled the various segments. There is no geomorphic evidence to suggest Redondo Canyon is fault controlled. The San Pedro fault can be extended more than 30 km to the northwest by the alignment of a series of bathymetric highs and abrupt changes in direction of channel thalwegs.

Además, la tendencia en mortalidad coronaria, descendente en pr��cticamente todas las áreas geográficas españolas, se ha incrementado en ésta ligeramente durante el periodo 1985-1991. En este estudio se evalúan las prevalencias poblacionales de diferentes factores de riesgo cardiovascular en la Región de Murcia. MÉTODOS: El trabajo se ha realizado mediante una encuesta a una población muestral representativa de la población adulta de la región (18-65 años, en la que se obtuvo una tasa de respuesta del 61%. Se realizó medición estandarizada de la tensión arterial, de la obesidad y de los lípidos séricos, junto a la aplicación de un cuestionario sobre consumo de tabaco, actividad física y diabetes. Presentación de datos estandarizados globales y truncados para los grupos de edad de 35-64 años. La recogida de información se llevó a cabo desde noviembre de 1991 a marzo de 1993. RESULTADOS: La prevalencia de consumo de tabaco resultante es de 54,4% en hombres y 31,3% en mujeres. Las cifras de hipertensión son superiores en los hombres (32,3% prevalencia, 16,4% tratamiento, 2,6% control del total de hipertensos y 15,6% control entre sólo los hipertensos tratados que en las mujeres (23,7%, 34,3%, 9,5% y 27,8%, respectivamente. Las cifras medias de colesterol son bajas en ambos sexos así como altas las cifras de HDL-colesterol en todos los grupos de edad. El Índice de Masa Corporal medio es 26,7 en ambos sexos, aunque las mujeres presentan una mayor variabilidad. La prevalencia de diabetes declarada se sitúa alrededor del 3-4%. CONCLUSIONES: Comparadas estas cifras, para los grupos de edad correspondientes, con las proporcionadas por el estudio MONICA y otros estudios en población adulta española se observa que, salvo el elevado consumo de tabaco y el alto índice de obesidad, la prevalencia de factores

    This study investigates age-related shifts in the relative importance of systolic (SBP) and diastolic (DBP) blood pressures as predictors of stroke and whether these relations are influenced by other cardiovascular risk factors. Using 34 European cohorts from the MOnica, Risk, Genetics, Archiving, and Monograph (MORGAM) Project with baseline between 1982 and 1997, 68 551 subjects aged 19 to 78 years, without cardiovascular disease and not receiving antihypertensive treatment, were included. During a mean of 13.2 years of follow-up, stroke incidence was 2.8%. Stroke risk was analyzed using hazard ratios per 10-mm Hg/5-mm Hg increase in SBP/DBP by multivariate-adjusted Cox regressions, including SBP and DBP simultaneously. Because of nonlinearity, DBP was analyzed separately for DBP ≥ 71 mm Hg and DBP <71 mm Hg. Stroke risk was associated positively with SBP and DBP ≥ 71 mm Hg (SBP/DBP ≥ 71 mm Hg; hazard ratios: 1.15/1.06 [95% CI: 1.12-1.18/1.03-1.09]) and negatively with DBP <71 mm Hg (0.88[0.79-0.98]). The hazard ratio for DBP decreased with age (P<0.001) and was not influenced by other cardiovascular risk factors. Taking into account the age × DBP interaction, both SBP and DBP ≥ 71 mm Hg were significantly associated with stroke risk until age 62 years, but in subjects older than 46 years the superiority of SBP for stroke risk exceeded that of DBP ≥ 71 mm Hg and remained significant until age 78 years. DBP <71 mm Hg became significant at age 50 years with an inverse relation to stroke risk. In Europeans, stroke risk should be assessed by both SBP and DBP until age 62 years with increased focus on SBP from age 47 years. From age 62 years, emphasis should be on SBP without neglecting the potential harm of very low DBP.

    Excess fat accumulates in the subcutaneous and visceral adipose tissue compartments. We tested the hypothesis that indicators of visceral adiposity, namely, waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR), are better predictors of stroke risk than body mass index (BMI). The association of BMI, WC, WHR, and WHtR with stroke was assessed in 31,201 men and 23,516 women, free of vascular disease at baseline, from the MOnica Risk, Genetics, Archiving and Monograph (MORGAM) study. During a mean follow-up of 11 years, 1130 strokes were recorded. Relative risks (95% CI) were calculated by Cox regression after stratification for center and adjustment for age, smoking, educational level, alcohol consumption, hypertension, diabetes, total cholesterol, high-density lipoprotein cholesterol, and BMI and model fit was assessed using log-likelihoods. BMI, WC, WHR, and WHtR were associated with the risk of stroke in men. After full adjustment including BMI, the relative risks for stroke remained significant for WC (1.19 [1.02 to 1.34] per 1 SD increase in WC), WHR (1.14 [1.03 to 1.26]), and WHtR (1.50 [1.28 to 1.77]). Among women, the extent of the associations with stroke risk was similar for WHtR (1.31 [1.04 to 1.65]), WC (1.19 [0.96 to 1.47]), and WHR (1.08 [0.97 to 1.22]). Further analyses by World Health Organization obesity categories showed that WC, WHR, and WHtR were associated with the risk of stroke also in lean men and women (BMI<25 kg/m2), independently of confounders, cardiovascular risk factors, and BMI. Indicators of abdominal adiposity, especially WHtR, are more strongly associated with stroke risk than BMI. These results emphasize the importance of measuring abdominal adiposity, especially in lean subjects.

    In April 2006, a domestic building consisting of eleven prefabricated steel modules and designed by architect Ralf Kappes was constructed at Santa Monica, California, within just eight hours. The two-storey building has a living area of 230 square metres. Rooms are open, with versetzte Ebenen.. The climate of the Los Angeles region is warm, with a constant sea breeze. The building is designed for natural ventilation, and no air conditioning system is required. If it gets too hot, warm air will be withdrawn by a blower in the upper Treppenhaus. In the winter season, the sun shines right into the interior of the building, where solar heat is stored and then slowly released by the concrete floor. A PV system on the roof generates 75 percent of the electric power required, and there is also a solar thermal power system for water heating. The building was awarded the LEED Platinum Award (Leadership in Energy and Environmental Design). (orig.) [German] Im April 2006 verfolgten zahlreiche Schaulustige, wie aus elf vorfabrizierten Stahlmodulen innerhalb von acht Stunden ein Wohnhaus entstand. Das Modulsystem stammt aus der Feder des Architekten Kappes. Die Stahlrahmenmodule bilden ein zweigeschossiges Wohnhaus mit 230 qm Wohnflaeche. Grosszuegige Luftraeume und versetzte Ebenen im Wohnbereich sowie zahlreiche Ein- und Ausblicke praegen die Architektur auf dem kompakten Hanggrundstueck in der Naehe des pazifischen Ozeans. Im warmen Klima von Los Angeles weht hier stets der Wind vom Meer. Das Haus ist so konzipiert, dass man sehr gut quer lueften kann. Es benoetigt keine Klimaanlage. Bei allzu grosser Hitze saugt ein Ventilator oben im Treppenhaus warme Luft ab. Im Winter reicht die tief stehende Sonne bis ins Hausinnnere. So kann die Sonnenwaerme vom Betonboden gespeichert und langsam abgegeben werden. Auf dem Dach erzeugt eine Photovoltaikanlage 75% des Strombedarfs. Ausserdem gibt es dort eine Solarthermieanlage fuer die Wasserversorgung. Dafuer erhielt das Wohnhaus die

  19. The geological setting of Santa Monica and San Pedro Basins, California Continental Borderland

    Science.gov (United States)

    Gorsline, D. S.

    The California Continental Borderland's present configuration dates from about 4 to 5 × 10 6 years before present (BP) and is the most recent of several configuration of the southern California margin that have evolved after the North America plate over-rode the East Pacific Rise about 30 × 10 6 years ago. The present morphology is a series of two to three northwest-southeast trending rows of depressions separated by banks and insular ridges. Two inner basins, Santa Monica and San Pedro, have been the site for the California Basin Study (CaBs), funded by the US Department of Energy. The Santa Monica and San Pedro Basins contain post-Miocene sediment thicknesses of about 2.5 and 1.5 km respectively. During the Holocene (past 10,000 years) about 10-12m have accumulated. The sediment entered the basin by one or a combination of processes including particle infall (mainly as bioaggregates) from surface waters, from nepheloid plumes (surface, mid-depth and near-bottom), from turbidity currents, mass movements, and to a very minor degree direct precipitation. In Santa Monica Basin, during the last century, particle infall nepheloid plume transport have been the most common processes. The former process has been dominant in thecentral basin at water depths from 900-945m, where characteristic silt-clay is found with a typical mean particle diameter of about 0.0006mm ( φ standard deviation = 2; φ skewness near zero). Kurtosis is typically 2 (platykurtic); these values indicate broad, near-log normal particle size distributions. The calcium carbonate content averages about 10% and organic carbon about 4%. Surficial sediment bulk densities are 1.1-1.2 and accumulation rates range from 16-30mg cm -2Yr 1 in this central fine deposit. Bottom water oxygen contents are at or below 0.1 ml 1 -1 so that bioturbation is inhibited, thus preserving the primary sedimentary stratification. There appear to be annual varves, but the laminae couplets are not simple wet-dry season pairs

    Full Text Available La implantación del Espacio Europeo de Educación Superior (EEES supone un cambio de paradigma respecto al proceso de enseñanza-aprendizaje, en el que el estudiante adquiere un papel activo en su proceso formativo ayudado por el profesor que deja de ser un mero transmisor de conocimiento. Esto requiere una reformulación de las metodologías docentes que favorezcan la participación activa del estudiante. Entre los recursos para implantar una metodología docente activa el profesor cuenta con los cuestionarios que podrían resultar útiles para mejorar la capacidad de aprendizaje autónomo del estudiante de la asignatura de contabilidad financiera, y por tanto su rendimiento académico. Para demostrar si esto es así, proponemos el siguiente trabajo cuyo objetivo es analizar la incidencia del uso de cuestionarios formativos sobre los rendimientos obtenidos por los estudiantes de la asignatura de Contabilidad Financiera impartida en la Universidad Autónoma de Barcelona (UAB. Para ello disponemos de datos pertenecientes a 543 estudiantes relativos a grupo en el que se han matriculado, estudios que cursan, nota de acceso a la universidad, número de veces matriculado en la asignatura, notas parciales y finales de la parte de teoría, y a la realización de los cuestionarios interactivos. Sobre dichos datos se han aplicado diferentes análisis de covarianza (ANCOVA, teniendo en cuenta que las pendientes del modelo conside-rado pueden ser homogéneas o heterogéneas. Los resultados obtenidos aportan evidencia de diferencias significativas en el rendimiento medio obtenido por los diferentes grupos de la asignatura. Por lo que podemos concluir que la incorporación de cuestionarios en la estrategia de enseñanza-aprendizaje contribuye a mejorar los resultados promedio obtenidos por los estudiantes en asignaturas de carácter introductorio y en materia contable.

    Contaminant inputs from wastewater discharge, a major source of contamination to Santa Monica Bay (SMB), have declined drastically during the last three decades as a result of improved treatment processes and better source control. To assess the concomitant temporal changes in the SMB sediments, a study was initiated in June 1997, in which 25 box cores were collected using a stratified random sampling design. Five sediment strata corresponding to the time intervals of 1890-1920, 1932-1963, 1965-1979, 1979-1989, and 1989-1997 were identified using 210Pb dating techniques. Samples from each stratum were analyzed for metals, 1,1,1-Trichloro-2,2-bis(p-chlorophenyl)ethane (DDT) and its metabolites (DDTs), polychlorinated biphenyls (PCBs), and total organic carbon (TOC). Samples from the 1965-1979, 1979-1989, and 1989-1997 strata were also analyzed for polycyclic aromatic hydrocarbons (PAHs) and linear alkylbenzenes (LABs). Sediment metal concentrations increased from 1890-1979 and were similar during the time intervals of 1965-1979, 1979-1989, and 1989-1997, although the mass emissions of trace metals from sewage inputs declined substantially during the same time period. Trace organic contamination in SMB was generally highest in sediments corresponding to deposition during the years of 1965-1979 or 1979-1989 and showed a decline in concentration in the 1989-1997 stratum. Temporal trends of contamination were greatest in sediments collected from areas near the Hyperion Treatment Plant (HTP) outfall system and on the slope of Redondo Canyon. The highest contaminant concentrations were present in sediments near the HTP 7-mile outfall in the 1965-1979 stratum. Elevated trace metal and organic concentrations were still present in the 1989-1997 stratum of most stations, suggesting that sediment contaminants have moved vertically in the sediment column since sludge discharges from the 7-mile outfall (a dominant source of contamination to the bay) ceased in 1987.

    Full Text Available The chemokine RANTES (regulated on activation, normal T-cell expressed and secreted/CCL5 is involved in the pathogenesis of cardiovascular disease in mice, whereas less is known in humans. We hypothesised that its relevance for atherosclerosis should be reflected by associations between CCL5 gene variants, RANTES serum concentrations and protein levels in atherosclerotic plaques and risk for coronary events.We conducted a case-cohort study within the population-based MONICA/KORA Augsburg studies. Baseline RANTES serum levels were measured in 363 individuals with incident coronary events and 1,908 non-cases (mean follow-up: 10.2±4.8 years. Cox proportional hazard models adjusting for age, sex, body mass index, metabolic factors and lifestyle factors revealed no significant association between RANTES and incident coronary events (HR [95% CI] for increasing RANTES tertiles 1.0, 1.03 [0.75-1.42] and 1.11 [0.81-1.54]. None of six CCL5 single nucleotide polymorphisms and no common haplotype showed significant associations with coronary events. Also in the CARDIoGRAM study (>22,000 cases, >60,000 controls, none of these CCL5 SNPs was significantly associated with coronary artery disease. In the prospective Athero-Express biobank study, RANTES plaque levels were measured in 606 atherosclerotic lesions from patients who underwent carotid endarterectomy. RANTES content in atherosclerotic plaques was positively associated with macrophage infiltration and inversely associated with plaque calcification. However, there was no significant association between RANTES content in plaques and risk for coronary events (mean follow-up 2.8±0.8 years.High RANTES plaque levels were associated with an unstable plaque phenotype. However, the absence of associations between (i RANTES serum levels, (ii CCL5 genotypes and (iii RANTES content in carotid plaques and either coronary artery disease or incident coronary events in our cohorts suggests that RANTES may not be a

    In a letter to the U.S. Geological Survey (USGS) dated March 25, 2008, Representative Jane Harman (California 36th district) requested advice on geologic hazards that should be considered in the review of a proposed liquefied natural gas (LNG) facility off the California coast in Santa Monica Bay. In 2004, the USGS responded to a similar request from Representative Lois Capps, regarding two proposed LNG facilities offshore Ventura County, Calif., with a report summarizing potential geologic and seismic hazards (Ross and others, 2004). The proposed LNG Deepwater Port (DWP) facility includes single point moorings (SPMs) and 35 miles of underwater pipelines. The DWP submersible buoys, manifolds, and risers would be situated on the floor of the southern Santa Monica Basin, in 3,000 feet of water, about 23 miles offshore of the Palos Verdes Peninsula. Twin 24-inch diameter pipelines would extend northeastward from the buoys across the basin floor, up the basin slope and across the continental shelf, skirting north around the Santa Monica submarine canyon. Figure 1 provides locations of the project and geologic features. Acronyms are defined in table 1. This facility is being proposed in a region of known geologic hazards that arise from both the potential for strong earthquakes and geologic processes related to sediment transport and accumulation in the offshore environment. The probability of a damaging earthquake (considered here as magnitude 6.5 or greater) in the next 30 years within about 30 miles (50 km) of the proposed pipeline ranges from 16% at the pipeline's offshore end to 48% where it nears land (Petersen, 2008). Earthquakes of this magnitude are capable of producing strong shaking, surface fault offsets, liquefaction phenomena, landslides, underwater turbidity currents and debris flow avalanches, and tsunamis. As part of the DWP license application for the Woodside Natural Gas proposal in Santa Monica Bay (known as the OceanWay Secure Energy Project), Fugro

    Samples from three time-series sediment traps deployed in the Santa Monica Basin off the California coast were analyzed to study the flux and scavenging of uranium and thorium series isotopes. Variations of uranium and thorium series isotopes fluxes in the water column were obtained by integrating these time-series deployment results. Mass and radionuclide fluxes measured from bottom sediment traps compare favorably with fluxed determined from sediment core data. This agreement suggests that the near-bottom sediment traps are capable of collecting settling particles representative of the surface sediment. The phase distributions of {sup 234}Th in the water column were calculated by an inverse method using sediment trap data, which help to study the variations of {sup 234}Th scavenging in the water column. Scavenging and radioactive decay of {sup 234}Th are the two principal processes for balancing {sup 234}Th budget in the water column. The residence times of dissolved and particulate {sup 234}Th were determined by a {sup 234}Th scavenging model.

    Distribution and flux of 234 Th, 232 Th and 230 Th in the water column of central Santa Monica basin observed over a period of seven years show seasonal and interannual variabilities. A steady-state model is applied to the integrated data to calculate long term average flux and model rate constants of Th isotopes. Mass balance calculations show that the basin acts like a closed system for short-lived 234 Th, but not for the long-lived isotopes 230 Th and 232 Th. Most 230 Th in the basin is transported from elsewhere. Of the incoming Th, 40-55% of the 230 Th and 14-26% of the 232 Th enter the surface water in dissolved form. In the upper 100m, the residence time of dissolved Th with respect to adsorption onto suspended particulates, 70-80 days, is about one order of magnitude higher than the residence time of suspended particles with respect to aggregation into sinking particles, 7-10 days.

    Full Text Available Lower levels of hemoglobin A1c (HbA1c are associated with a decreased risk of cardiovascular complications in diabetic and non-diabetic individuals. The aim of the study was to longitudinally investigate the association between the use of 11 vitamins and minerals (vitamins E, C, D, B1, folic acid, carotenoids, calcium, magnesium, zinc, iron, and selenium and change in HbA1c levels over 10 years in non-diabetic individuals drawn from the general population.Baseline data were available from 4447 subjects included in the population-based "Monitoring of Trends and Determinants in Cardiovascular Diseases" (MONICA Augsburg S3 survey (1994/95. Follow-up data were derived from 2774 participants in the follow-up survey named "Cooperative Health Research in the Region of Augsburg" (KORA F3 (2004/05. Vitamin/mineral intake from supplements and medications was assessed in a personal interview, where participants were asked to bring product packages of preparations that had been ingested during the last 7 days prior to the examination. Associations between regular vitamin/mineral intake amounts and HbA1c levels measured at baseline and follow-up were investigated using generalized estimating equation models. For carotenoids, analyses were stratified by smoking status.None of the investigated nutrients except for carotenoids was significantly associated with changes in HbA1c levels after 10 years. Regular intake of carotenoids from supplements and medications in amounts > 6.8 mg/d (upper tertile was associated with an absolute -0.26% (95% CI: -0.43 to -0.08 lower increase in HbA1c levels compared with no intake of carotenoids. An inverse association was observed in those who never smoked but not in (former smokers.Larger prospective and intervention studies in non-diabetic/non-smoking individuals are needed to confirm the results and to assess whether the observed associations between carotenoid intake and change in HbA1c levels are causal.

    This paper is aimed to discuss the involvement of delayed radiation effects of A-bomb exposure in cardiovascular diseases. First, the relationship between radiation and cardiovascular diseases is reviewed in the literature. Animal experiments have confirmed the relationship between ionizing radiation and vascular lesions. There are many reports which describe ischemic heart disease, cervical and cerebrovascular diseases, and peripheral disease occurring after radiation therapy. The previous A-bomb survivor cohort studies, i.e., the RERF Life Span Study and Adult Health Study, have dealt with the mortality rate from cardiovascular diseases, the prevalence or incidence of cardiovascular diseases, pathological findings, clinical observation of arteriosclerosis, ECG abnormality, blood pressure abnormality, and cardiac function. The following findings have been suggested: (1) A-bomb exposure is likely to be involved in the mortality rate and incidence of ischemic heart disease and cerebrovascular diseases; (2) similarly, the involvement of A-bomb exposure is considered in the prevalence of the arch of aorta; (3) ECG abnormality corresponding to ischemic heart disease may reflect the involvement of A-bomb exposure. To confirm the above findings, further studies are required on the basis of more accurate information and the appropriate number of cohort samples. Little evidence has been presented for the correlation between A-bomb exposure and both rheumatic heart disease and congenital heart disease. (N.K.) 88 refs

    Full Text Available El artículo evalúa la estructura factorial bajo los efectos del método ipsativo de respuesta, estudiados en el nivel de las subescalas del Cuestionario de Valores Interpersonales de Gordon (SIV, y las relaciones entre ellas, en una muestra de adolescentes entre 15 y 17 años de ambos sexos y procedentes de un colegio privado y estatal, representativos de los niveles socioeconómicos medio y bajo. Aunque el SIV ha sido una herramienta extensamente utilizada, no se reportado previamente un análisis de su estructura factorial en muestras Latinoamericanas. Mediante el análisis de componentes principales y el análisis factorial con un enfoque confirmatorio, se han identificado relaciones bipolares entre Independencia y Benevolencia, y Soporte y Conformidad. Se obtuvo también la confirmación del modelo de valores interpersonales propuesto por L. V. Gordon. En el análisis se consideró un aspecto que artificialmente puede haber influido en el patrón de correlaciones entre los componentes, esto es el método ipsativo de las preguntas del SIV. Finalmente, se discute sobre las medidas ipsativas y sus consecuencias en la interpretación de sus resultados. The present study evaluates the factorial structure, in the level of the subscales, of the Survey of Interpersonal Values (SIV, and the relationships among them, in a sample of adolescents between 15 and 17 years old of both sexes and from a private and public school, representative of low and middle socioeconomic levels. Although the SIV has been a widely used tool, there is no report of an analysis of its factorial structure in Latin-American samples. By means of the principal components analysis and the factorial analysis with a confirmatory approach, bipolar relationships have been identified between Independence and Benevolence, and Support and Conformity.

    Full Text Available La regulación de la emoción es un proceso complejo que implica la iniciación, inhibición o modulación del propio estado o comportamiento en una situación dada (Cole, Michel & Teti, 1994. La regulación emocional tiene una función altamente significativa en la vida humana ya que reacciones emocionales inapropiadas, extremas o incontroladas pueden impedir un ajuste funcional a la sociedad (Koole, 2009. Sin embargo para una adecuada regulación emocional es necesaria una buena comprensión emocional y, a su vez, para una comprensión eficaz se requiere una apro piada percepción emocional. En este estudio se analizan las propiedades psicométricas de la ver sión española del Cuestionario de Conciencia Emocional revisado ( Emotional Awareness Ques tionnaire , EAQ30 desarrollado por Rieffe, Oos terveld, Miers, Terwogt y Ly (2008. La versión española del EAQ30 fue administrada a 1.316 adolescentes españoles de 14 a 16 años.

    Invasive cardiovascular diagnostic procedures involve a finite risk and therefore can be recommended only when the benefit appears to exceed the risk by a substantial margin. The risk/benefit ratio varies not only with the procedure concerned but with the status of the vascular system, concomitant diseases, and the risks of both the suspected illness and its treatment. The risks inherent in the procedures per se are detailed in the sections to follow

    This study provides psychometric information for the Dating Violence Questionnaire (DVQ), an instrument developed to assess intimate partner victimization among adolescents and youths. This instrument, an English version of Cuestionario de Violencia de Novios, assesses both frequency and discomfort associated with 8 types of abuse (detachment, humiliation, sexual, coercion, physical, gender-based, emotional punishment, and instrumental). Participant included 859 U.S. students enrolled in undergraduate psychology courses in a mid-Atlantic university (M = 19 years; SD = 1.5 years). One-third of the participants were males, and two-thirds were females. Regarding racial identity, around 55% of participants identified themselves as White, 22% as African American, 12% as Asian, whereas 11% selected other identities. Around 9% of participants identified themselves as Hispanic. Confirmatory factor analysis shows that the DVQ achieved adequate goodness-of-fit indexes for the original eight-factor model (X(2)/df .700), surpassing those found in the original Spanish validation. Descriptive analysis suggests higher victimization experience on subtle aggressions (detachment, coercion, and emotional punishment), with overt abuses (physical, instrumental) obtaining the smallest means; these findings were similar across gender, race identity, and ethnicity. Results of this validation study encourage the inclusion of DVQ in both research and applied contexts.

  19. Coarse-grained sediment delivery and distribution in the Holocene Santa Monica Basin, California: Implications for evaluating source-to-sink flux at millennial time scales

    Utilizing accumulations of coarse-grained terrigenous sediment from deep-marine basins to evaluate the relative contributions of and history of controls on sediment flux through a source-to-sink system has been difficult as a result of limited knowledge of event timing. In this study, six new radiocarbon (14C) dates are integrated with five previously published dates that have been recalibrated from a 12.5-m-thick turbidite section from Ocean Drilling Program (ODP) Site 1015 in Santa Monica Basin, offshore California. This borehole is tied to high-resolution seismic-reflection profiles that cover an 1100 km2 area of the middle and lower Hueneme submarine fan and most of the basin plain. The resulting stratigraphic framework provides the highest temporal resolution for a thick-bedded Holocene turbidite succession to date, permitting an evaluation of source-to-sink controls at millennial (1000 yr) scales. The depositional history from 7 ka to present indicates that the recurrence interval for large turbidity-current events is relatively constant (300-360 yr), but the volume of sediment deposited on the fan and in the basin plain has increased by a factor of 2 over this period. Moreover, the amount of sand per event on the basin plain during the same interval has increased by a factor of 7. Maps of sediment distribution derived from correlation of seismic-reflection profiles indicate that this trend cannot be attributed exclusively to autogenic processes (e.g., progradation of depocenters). The observed variability in sediment accumulation rates is thus largely controlled by allogenic factors, including: (1) increased discharge of Santa Clara River as a result of increased magnitude and frequency of El Ni??o-Southern Oscillation (ENSO) events from ca. 2 ka to present, (2) an apparent change in routing of coarse-grained sediment within the staging area at ca. 3 ka (i.e., from direct river input to indirect, littoral cell input into Hueneme submarine canyon), and (3

    Suicide is strongly associated with mental disorders, particularly with depression. There is insufficient knowledge to what extent sociodemographic and behavioral characteristics contribute to suicide risk. A population-based cohort study on three independent cross-sectional MONICA/KORA Augsburg surveys with 12,888 subjects (6456 men, 6432 women) was followed up on average for 12.0 years. Information on sociodemographic characteristics, chronic disease conditions, smoking habits, alcohol consumption, depressive symptoms, personality type, and other psychodiagnostic parameters was assessed by standardized interviews. Cox proportional hazards regression analyses were used to compute hazard ratios (HRs) as estimates of relative risks for suicide mortality. Additionally, population-attributable risks were calculated. Within the follow-up period, a total of 1449 persons had died, 38 of them by suicide. Although several variables were associated with increased risk in the basic analyses, only obesity (HR=2.73), smoking (HR=2.23), and living alone (HR=2.19) remained significantly associated with suicide additionally to male sex (HR=3.57) and depressed mood (HR=2.01) in a multivariate analysis. The generalization of our findings to countries with different social, economic or cultural conditions may be questioned. Our findings extend the knowledge about sociodemographic and behavioral risk factors for suicide in the general population: Suicide prevention measures should not consider only subjects with mental disorders but also address other adverse conditions. © 2013 Published by Elsevier B.V.

    Depressed individuals not only suffer from chronic low grade inflammation, but also exhibit an inflammatory hyper-responsiveness to acute stress. We investigate whether chronic stress also induces an exaggerated inflammatory response in individuals with increased depression features. As model for chronic stress, social isolation was chosen. Interleukin (IL)-6 and hs-CRP levels were assessed in 1547 subjects (847 men and 700 women), derived from the population-based MONICA/KORA study. Standardized questionnaires were used to assess depressed mood (depression and exhaustion subscale) and social isolation (social network index). The relationship between the two inflammatory markers, social isolation and depressed mood was examined taking into account interactions social isolation × depressed mood using multivariable linear regression models, adjusted for age, BMI, smoking, alcohol, and physical activity. Analyses were performed in men and women separately. We observed a significant interaction between depressed mood and social isolation regarding IL-6 and hs-CRP, respectively in men (p-value=0.02 for IL-6 and social isolation, and depressed mood on inflammatory responses. Furthermore, depressed and socially isolated men had highly significantly elevated IL-6 levels (geometric mean: 3.76 vs. 1.92 pg/ml, p-value socially integrated men. In women, no significant associations were seen. The interaction of depressed mood and social isolation elicits a substantial synergistic impact on inflammatory markers in men, but not in depressed women. Copyright © 2011 Elsevier Inc.

    Full Text Available The profound structural changes in society over recent years are reflected in the deepening of social, economic and political inequalities, which have characterized our reality and that of several Latin American countries. In this social setting, violence appears as a disturbing phenomenon due to its varied expressions and environments of development. This growing social vulnerability fosters delinquency resulting in a safety crisis as its major effect. The widely accepted relevance of current insecurity in the field of social and legal phenomena requires a response from government as well as social organizations. Its effects on the restriction of social well being and its massive implications deserve to be included in research agendas with the objective of integrating research and intervention strategies. Unsafe city life is a problem with great incidence in human beings, politics and economics, and it questions the capacity of government and control entities to preserve human rights. Therefore, the incidence of this phenomenon is twofold: it affects the quality of life at an individual level and the processes of community development at a collective level due to their political and economic impact. In this paper, the final version of the Unsafe City Life Questionnaire (Cuestionario de Inseguridad Urbana - CIU is described. It attempts to be a specific psychological instrument which measures insecurity, considering insecurity as the current phenomenon that affects the health of urban inhabitants in the city of San Luis (Argentina. This paper deals with theoretical foundations and psychometric characteristics of the inventory, and it provides the scales resulting from the administration of the CIU to a large sample of young people divided into two groups: crime victims and non-crime victims. From the statistics viewpoint, the reliability of the questionnaire, i.e. its internal consistency, has been studied and demonstrated using the alpha

    Several psychosocial factors have been shown to increase the risk of Type 2 diabetes mellitus. This study investigated the association between structural social support and incidence of Type 2 diabetes mellitus in men and women. Data were derived from three population-based MONICA/KORA surveys conducted in 1984-1995 in the Augsburg region (southern Germany) and followed up by 2009. The study population comprised 8952 participants (4669 men/4283 women) aged 30-74 years without diabetes at baseline. Structural social support was assessed using the Social Network Index. Sex-specific hazard ratios were estimated from Cox proportional hazard models. Within follow-up, 904 incident Type 2 diabetes mellitus cases (558 men, 346 women) were observed. Crude incidence rates for Type 2 diabetes mellitus per 10 000 person-years were substantially higher in poor compared with good structural social support (men: 94 vs. 69, women: 58 vs. 43). After adjustment for age, survey, parental history of diabetes, smoking status, alcohol intake, physical activity, hypertension, dyslipidaemia, BMI, education, sleep complaints and depressed mood, risk of Type 2 diabetes mellitus for participants with poor compared with good structural social support was 1.31 [95% confidence interval (CI) = 1.11-1.55] in men and 1.10 (95% CI = 0.88-1.37) in women. Stratified analyses revealed a hazard ratio of 1.50 (95% CI = 1.23-1.83) in men with a low level of education and 0.87 (95% CI = 0.62-1.22) in men with a high level of education (P for interaction: 0.0082). Poor structural social support is associated with Type 2 diabetes mellitus in men. This association is independent of risk factors at baseline and is particularly pronounced in men with a low level of education. © 2015 The Authors. Diabetic Medicine © 2015 Diabetes UK.

    Full Text Available Objectives: To assess the yield of medical record review to recover missing data originally collected by questionnaire, to analyze the agreement between these two data sources and to determine interobserver variability in clinical record review. Methods: We analyzed data from a birth cohort of 8,127 women who were consecutively recruited after giving birth from 2005-2006. Recruitment was conducted at all public maternity units of Porto, Portugal. We reviewed the medical records of 3,657 women with missing data in the baseline questionnaire and assessed agreement between these two sources by using information from participants with data from both sources. Interobserver variability was assessed by using 400 randomly selected clinical records. Results: Data on pregnancy complications and maternal anthropometric parameters were successfully recovered. Agreement between the questionnaire and records in family history data was fair, particularly for cardiovascular disease [k=0.27; 95% confidence interval (95%CI: 0.23-0.32]. The highest agreement was observed for personal history of diabetes (k=0.82; 95%CI 0.70-0.93, while agreement for hypertension was moderate (k=0.60; 95%CI 0.50-0.69. Discrepancies in prepregnancy body mass index classes were observed in 10.3% women. Data were highly consistent between the two reviewers, with the highest agreement found for gestational diabetes (k=1.00 and birth weight (99.5% concordance. Conclusion: Data from the medical records and questionnaire were concordant with regard to pregnancy and well-known risk factors. The low interobserver variability did not threaten the precision of our data.Objetivo: Evaluar el rendimiento de la revisión de registros médicos para completar datos originalmente recogidos por cuestionario, y analizar la concordancia entre ambas fuentes de datos y la variabilidad interobservador en la revisión de registros médicos.

  3. Postirradiation cardiovascular dysfunction

    Cardiovascular dysfunction may be defined as the inability of any element of the cardiovascular system to perform adequately upon demand, leading to inadequate performance and nutritive insufficiency of various parts of the body. Exposure to supralethal doses of radiation (accidental and therapeutic) has been show to induce significant alterations in cardiovascular function in man. These findings indicate that, after irradiation, cardiovascular function is a major determinant of continued performance and even survival. For the two persons who received massive radiation doses (45 and 88 Gy, respectively) in criticality accidents, the inability to maintain systematic arterial blood pressure (AP) was the immediate cause of death. In a study of cancer patients given partial-body irradiation, two acute lethalities were attributed to myocardial infarction after an acute hypotensive episode during the first few hours postexposure. Although radiation-induced cardiovascular dysfunction has been observed in many species, its severity, duration, and even etiology may vary with the species, level of exposure, and dose rate. For this reason, our consideration of the effects of radiation on cardiovascular performance is limited to the circulatory derangements that occur in rat, dog, and monkey after supralethal doses and lead to radiation-induced cardiovascular dysfunction in these experimental models. The authors consider other recent data as they pertain to the etiology of cardiovascular dysfunction in irradiated animals

  14. Caffeine and cardiovascular health.

    2017-10-01

    This report evaluates the scientific literature on caffeine with respect to potential cardiovascular outcomes, specifically relative risks of total cardiovascular disease (CVD), coronary heart disease (CHD) and acute myocardial infarction (AMI), effects on arrhythmia, heart failure, sudden cardiac arrest, stroke, blood pressure, hypertension, and other biomarkers of effect, including heart rate, cerebral blood flow, cardiac output, plasma homocysteine levels, serum cholesterol levels, electrocardiogram (EKG) parameters, heart rate variability, endothelial/platelet function and plasma/urine catecholamine levels. Caffeine intake has been associated with a range of reversible and transient physiological effects broadly and cardiovascular effects specifically. This report attempts to understand where the delineations exist in caffeine intake and corresponding cardiovascular effects among various subpopulations. The available literature suggests that cardiovascular effects experienced by caffeine consumers at levels up to 600 mg/day are in most cases mild, transient, and reversible, with no lasting adverse effect. The point at which caffeine intake may cause harm to the cardiovascular system is not readily identifiable in part because data on the effects of daily intakes greater than 600 mg is limited. However, the evidence considered within this review suggests that typical moderate caffeine intake is not associated with increased risks of total cardiovascular disease; arrhythmia; heart failure; blood pressure changes among regular coffee drinkers; or hypertension in baseline populations.

    Full Text Available La percepción de la importancia que el empleado otorga a los distintos aspectos de su trabajo es una base de la representación social que tiene de la empresa en la que labora y de las actitudes hacia su trabajo, como la intención de abandono, que también se relacionan con aspectos no controlables por la empresa. El propósito de este estudio fue diseñar y probar un cuestionario para medir la importancia que los trabajadores conceden a los aspectos laborales e identificar su relación con la intención de abandonar la organización. El cuestionario se aplicó a 447 trabajadores (282 hombres y 165 mujeres de empresas exportadoras de calzado de la ciudad de León, Guanajuato, México. Mediante un análisis factorial se identificaron cinco factores; la consistencia interna fue adecuada en todos los casos y la discriminación de todos los ítems resultó en la dirección esperada. La percepción sobre los factores del trabajo varió en importancia y no se relacionó con la intención de abandono, aunque un aspecto no controlable por la empresa (mejor salario reveló indicios de una relación sobre la intención de abandono.

    The competition for public cardiovascular research grants has recently increased. Independent researchers are facing increasing competition for public research grant support and ultimately may need to seek alternative funding sources. Crowdfunding, a financing method of raising funds online by pooling together small donations from the online community to support a specific initiative, seems to have significant potential. However, the feasibility of crowdfunding for cardiovascular research remains unknown. Here, we performed exploratory data analysis of the feasibility of online crowdfunding in cardiovascular research. Copyright © 2017 Elsevier B.V. All rights reserved.

    Although huge and long-lasting research efforts have been spent on the development of new diagnostic techniques investigating cardiovascular diseases, still fundamental challenges exist; the main challenge being the diagnosis of a suspected or known coronary artery disease or its consequences (myocardial infarction, heart failure etc.). Beside morphological techniques, functional imaging modalities are available in clinical diagnostic algorithms, whereas molecular cardiovascular imaging techniques are still under development. This review summarizes clinical-diagnostical challenges of modern cardiovascular medicine as well as the potential of new molecular imaging techniques to face these. (orig.)

    Full Text Available BACKGROUND: This study compares inflammation-related biomarkers with established cardiometabolic risk factors in the prediction of incident type 2 diabetes and incident coronary events in a prospective case-cohort study within the population-based MONICA/KORA Augsburg cohort. METHODS AND FINDINGS: Analyses for type 2 diabetes are based on 436 individuals with and 1410 individuals without incident diabetes. Analyses for coronary events are based on 314 individuals with and 1659 individuals without incident coronary events. Mean follow-up times were almost 11 years. Areas under the receiver-operating characteristic curve (AUC, changes in Akaike's information criterion (ΔAIC, integrated discrimination improvement (IDI and net reclassification index (NRI were calculated for different models. A basic model consisting of age, sex and survey predicted type 2 diabetes with an AUC of 0.690. Addition of 13 inflammation-related biomarkers (CRP, IL-6, IL-18, MIF, MCP-1/CCL2, IL-8/CXCL8, IP-10/CXCL10, adiponectin, leptin, RANTES/CCL5, TGF-β1, sE-selectin, sICAM-1; all measured in nonfasting serum increased the AUC to 0.801, whereas addition of cardiometabolic risk factors (BMI, systolic blood pressure, ratio total/HDL-cholesterol, smoking, alcohol, physical activity, parental diabetes increased the AUC to 0.803 (ΔAUC [95% CI] 0.111 [0.092-0.149] and 0.113 [0.093-0.149], respectively, compared to the basic model. The combination of all inflammation-related biomarkers and cardiometabolic risk factors yielded a further increase in AUC to 0.847 (ΔAUC [95% CI] 0.044 [0.028-0.066] compared to the cardiometabolic risk model. Corresponding AUCs for incident coronary events were 0.807, 0.825 (ΔAUC [95% CI] 0.018 [0.013-0.038] compared to the basic model, 0.845 (ΔAUC [95% CI] 0.038 [0.028-0.059] compared to the basic model and 0.851 (ΔAUC [95% CI] 0.006 [0.003-0.021] compared to the cardiometabolic risk model, respectively.

    2017-01-01

    In patients with acromegaly, chronic excess of growth hormone (GH) and insulin-like growth factor-1 (IGF-1) leads to the development of acromegalic cardiomyopathy. Its main features are biventricular hypertrophy, diastolic dysfunction, and in later stages, systolic dysfunction and congestive heart failure. Surgical and/or pharmacological treatment of acromegaly and control of cardiovascular risk factors help reverse some of these pathophysiologic changes and decrease the high risk of cardiovascular complications.

    Full Text Available En este trabajo se desarrolló un cuestionario de 30 preguntas para calcular la huella ecológica (HE de estudiantes universitarios mexicanos, considerando el estilo de vida y el patrón de consumo propios de la cultura mexicana. Primero, se obtuvo de anuarios estadísticos la productividad promedio (en ton/ha/año, de los bienes agropecuarios y pesqueros más demandados, y de papel de cuadernos escolares, con la finalidad de determinar la superficie que se requiere para producir el consumo anual del mexicano promedio, por tipo de bien; también, se calculó el área promedio para absorber el dióxido de carbono generado por el consumo de energía directo (debido al uso de transportes, de equipos electrónicos, de agua caliente para ducharse y de agua potable de empleo cotidiano, e indirecto (producción, distribución y comercialización de productos. Posteriormente, se transformaron las superficies obtenidas a hectáreas globales (hag mediante factores de conversión y se aplicó el cuestionario a 125 alumnos universitarios obteniendo una HE de 1.48 hag, con resultado de mayor impacto ambiental individual al rubro de alimentos (0.42 hag por el consumo de cárnicos, seguido del uso de energía (0.35 hag, principalmente por utilizar gas LP en la ducha cotidiana. Esta HE está dentro de los límites de sustentabilidad global (< 1.61 hag. No hubo diferencias significativas debidas al nivel de estudios, edad o sexo de la muestra. Finalmente, se concluye que el instrumento desarrollado es coherente con los resultados obtenidos de cuestionarios disponibles en línea y elaborados en países de alto nivel de consumo de bienes y servicios y que aquí se presenta la primera calculadora de huella ecológica que toma en cuenta la idiosincrasia mexicana.

    Full Text Available El envejecimiento del sistema cardiovascular está asociado con un número característico de cambios a nivel bioquímico, histológico y morfológico. Sin embargo, no todas las modificaciones presentadas se asocian con deterioro en la función. Entre los cambios a nivel cardiaco se tienen: disminución en el número de miocitos y en las células del sistema de conducción cardiaca, desarrollo de fibrosis, cambios en el transporte de calcio a través de las membranas y disminución del cronotropismo, inotropismo y lusitropismo mediados por estímulo b-adrenérgico. A nivel vascular, hay incremento en la rigidez de la pared de las arterias, con aumento en la velocidad de la onda de pulso, disfunción endotelial y disminución de la vasodilatación mediada por estímulo b-adrenérgico. Durante el reposo el sistema cardiovascular es capaz de desarrollar mecanismos adaptativos eficientes, pero en situaciones de estrés como el ejercicio, los cambios asociados con el envejecimiento se hacen evidentes ya que está disminuida la capacidad para obtener la frecuencia cardiaca máxima, está incrementada la postcarga y hay disminución de la contractilidad intrínseca. Por lo anterior, los ancianos deben utilizar al máximo el mecanismo de Frank-Starling para mantener el gasto cardiaco. Los cambios estructurales y funcionales asociados con el envejecimiento cardiovascular, disminuyen de forma significativa el umbral en el cual las enfermedades cardiacas llegan a ser evidentes, y deben ser conocidos por el personal de salud encargado de cuidar a los ancianos.Cardiovascular aging is associated with characteristic biochemical, histological and morphological changes. Nevertheless, these changes are not necessarily associated to a deterioration in its function. Among the cardiac changes found, there is a reduction in the number of myocytes and of the cardiac conduction system cells, development of fibrosis, changes in the trans-membrane calcium transport and a

    This study aimed to evaluate the feasibility, acceptability, ceiling and floor effects, reliability, and convergent construct validity of the Brazilian version of the Mini Cuestionario de Calidad de Vida en la Hipertensión Arterial (MINICHAL). The study included 200 hypertensive outpatients in a university hospital and a primary healthcare unit. The MINICHAL was applied in 3.0 (± 1.0) minutes with 100% of the items answered. A "ceiling effect" was observed in both dimensions and in the total score, as well as evidence of measurement stability (ICC=0.74). The convergent validity was confirmed by significant positive correlations between similar dimensions of the MINICHAL and the SF-36, and significant negative correlations with the Minnesota Living with Heart Failure Questionnaire - MLHFQ, however, correlations between dissimilar constructs were also observed. It was concluded that the Brazilian version of the MINICHAL presents evidence of reliability and validity when applied to hypertensive outpatients.

    Full Text Available En el presente estudio, 156 estudiantes costarricenses entre los 19 y los 29 años (promedio de edad =22,7, SD= 2,35 años, 59% mujeres describieron sus percepciones sobre la comunicación intergeneracional a través de la versión costarricense del Cuestionario de Percepción de la Comunicación Interpersonal (CPCI. En este cuestionario se le solicita a los y las entrevistados pensar en sus encuentros cotidianos con personas de diferentes grupos de edad fuera del ambiente familiar y evaluar tanto las conductas de comunicación de los otros como las propias. Los análisis de factores exploratorios mostraron que el CPIC accede a tres dimensiones evaluativos sobre las conductas comunicativas de los otros (acomodación, sub-comodación y control de la comunicación y dos dimensiones de evaluación de la propia conducta comunicativa (descontento/obligación y manejo del discurso. Los análisis de consistencia interna mostraron índicas Alfas de Cronbach satisfactorios para todas las escalas. Diferencias significativas en la percepción de la comunicación dependiendo del grupo etario de los interloculores indican que el instrumento es sensible a las variaciones de la comunicación intergeneracional dadas por las características específicas de las personas involucradas en la interacción. Las correlaciones de las escalas con mediciones de la frecuencia de contacto intergeneracional e identificación social con el endogrupo erario muestran evidencia mixta sobre la validez de constructo del instrumento. Los resultados se discuten en términos de las propiedades psicométricas del instrumento y las características de la comunicación intergeneracional en contextos latinoamericanos.

    Full Text Available Diabetes is a well-known risk factor of cardiovascular morbidity and mortality, and the beneficial effect of improved glycemic control on cardiovascular complications has been well established. However, the rosiglitazone experience aroused awareness of potential cardiovascular risk associated with diabetes drugs and prompted the U.S. Food and Drug Administration to issue new guidelines about cardiovascular risk. Through postmarketing cardiovascular safety trials, some drugs demonstrated cardiovascular benefits, while some antidiabetic drugs raised concern about a possible increased cardiovascular risk associated with drug use. With the development of new classes of drugs, treatment options became wider and the complexity of glycemic management in type 2 diabetes has increased. When choosing the appropriate treatment strategy for patients with type 2 diabetes at high cardiovascular risk, not only the glucose-lowering effects, but also overall benefits and risks for cardiovascular disease should be taken into consideration.

    There is increasing evidence for a protective effect of tea consumption against cardiovascular disease. This review summarizes the available epidemiological data providing evidence for and against such an effect. We also review observational and intervention studies that investigated an effect of tea and tea extracts on cardiovascular risk factors, including blood pressure, serum lipids, diabetes mellitus, and obesity. Finally, we review potential mechanisms of benefit, including anti-inflammatory, anti-oxidant, and anti-proliferative effects, as well as favorable effects on endothelial function. Overall, the observational data suggest a benefit, but results are mixed and likely confounded by lifestyle and background dietary factors. The weight of evidence indicates favorable effects on risk factors and a number of plausible mechanisms have been elucidated in experimental and translational human studies. Despite the growing body evidence, it remains uncertain whether tea consumption should be recommended to the general population or to patients as a strategy to reduce cardiovascular risk.

MATERIAL Y MÉTODOS: La muestra quedó integrada por 1 301 estudiantes. En una submuestra de 293 sujetos se midieron lípidos séricos, con un analizador químico Hitachi 717. La obesidad se estimó considerando el índice de masa corporal (IMC; el antecedente familiar de infarto, así como el consumo de cigarrillos y el nivel de actividad física se determinaron mediante un cuestionario de autoevaluación. Se construyeron tablas de contingencia para estudiar asociaciones entre factores de riesgo lipídicos y no lipídicos, usando la prueba ji² de Pearson. Se realizó un análisis de regresión múltiple para determinar la relación de cada una de las variables lipídicas (colesterol total, colesterol-lipoproteína de baja densidad, colesterol-lipoproteína de alta densidad y triglicéridos, así como de las no lipídicas (edad, peso, estatura, IMC, sexo, presión arterial, conducta sedentaria y antecedente familiar de infarto precoz. RESULTADOS: Se encontraron niveles de riesgo lipídico en 29.2% de los casos para colesterol total, en 16.2% para lipoproteína de baja densidad y en 5% para lipoproteína de alta densidad. Entre los factores de riesgo no lipídicos más prevalentes, estaban el consumo de cigarrillos, con 46.1%, y el sedentarismo, que alcanzó 60.8%. La obesidad, la hipertensión arterial y el antecedente familiar alcanzaron 1.9, 4.6 y 11%, respectivamente. Se observó una asociación entre el perfil lipídico de riesgo, la obesidad, la conducta fumadora y el antecedente familiar. CONCLUSIONES: Los resultados mostraron una alta prevalencia de sedentarismo y conducta fumadora, asociada a un perfil lipídico de riesgo. Se deduce la necesidad imperiosa de diseñar programas de intervención con el fin de modificar el estilo de vida y prevenir la posible presencia de enfermedades

  12. Nutrition and cardiovascular health.

    2014-09-01

    A multitude of studies have been published on the relationship between cardiovascular disease risk and a variety of nutrients, foods, and dietary patterns. Despite the well-accepted notion that diet has a significant influence on the development and prevention of cardiovascular disease, the foods considered healthy and harmful have varied over the years. This review aims to summarize the current scientific evidence on the cardioprotective effect of those foods and nutrients that have been considered healthy as well as those that have been deemed unhealthy at any given time in history. For this purpose, we reviewed the most recent literature using as keywords foods and nutrients (ie, meat, omega-3) and cardiovascular disease-related terms (ie, cardiovascular diseases, stroke). Emphasis has been placed on meta-analyses and Cochrane reviews. In general, there is a paucity of intervention studies with a high level of evidence supporting the benefits of healthy foods (ie, fruits and vegetables), whereas the evidence supporting the case against those foods considered less healthy (ie, saturated fat) seems to be weakened by most recent evidence. In summary, most of the evidence supporting the benefits and harms of specific foods and nutrients is based on observational epidemiological studies. The outcome of randomized clinical trials reveals a more confusing picture with most studies providing very small effects in one direction or another; the strongest evidence comes from dietary patterns. The current status of the relationship between diet and cardiovascular disease risk calls for more tailored recommendations based on genomic technologies.

    Few studies have investigated the independent effects of domain-specific physical activity on mortality. We sought to investigate the association of physical activity performed in different domains of daily living on all-cause, cardiovascular (CVD) and cancer mortality. Using a prospective cohort design, 4,672 men and women, aged 25-74 years, who participated in the baseline examination of the MONICA/KORA Augsburg Survey 1989/1990 were classified according to their activity level (no, light, moderate, vigorous). Domains of self-reported physical activity (work, transportation, household, leisure time) and total activity were assessed by the validated MOSPA (MONICA Optional Study on Physical Activity) questionnaire. After a median follow-up of 17.8 years, a total of 995 deaths occurred, with 452 from CVD and 326 from cancer. For all-cause mortality, hazard ratios and 95% confidence interval (HR, 95% CI) of the highly active versus the inactive reference group were 0.69 (0.48-1.00) for work, 0.48 (0.36-0.65) for leisure time, and 0.73 (0.59-0.90) for total activity after multivariable adjustments. Reduced risks of CVD mortality were observed for high levels of work (0.54, 0.31-0.93), household (0.80, 0.54-1.19), leisure time (0.50, 0.31-0.79) and total activity (0.75, 0.55-1.03). Leisure time (0.36, 0.23-0.59) and total activity (0.62, 0.43-0.88) were associated with reduced risks of cancer mortality. Light household activity was related to lower all-cause (0.82, 0.71-0.95) and CVD (0.72, 0.58-0.89) mortality. No clear effects were found for transportation activities. Our findings suggest that work, household, leisure time and total physical activity, but not transportation activity, may protect from premature mortality.

    Full Text Available Fundamentos: Las Lesiones por Tráfico continúan siendo un importante problema de Salud Pública en población joven. A pesar de ello, no existen en nuestro país cuestionarios idóneos para la investigación epidemiológica de este problema. El objetivo del presente trabajo fue diseñar y validar un cuestionario orientado a explorar la frecuencia de implicación en circunstancias de conducción teóricamente asociadas con la accidentalidad por tráfico en población universitaria. Métodos: Se aplicó un cuestionario autoadministrado (MATCA: movilidad, accidentalidad por tráfico y circunstancias asociadas a 1597 jóvenes alumnos de grado de la Universidad de Granada, entre los años 2007 y 2010, que recogía información, entre otras variables, sobre la exposición, la accidentalidad y la implicación en 28 circunstancias de conducción. Para su diseño se realizó una extensa revisión de la literatura al respecto y se contó con el juicio de un panel de cinco expertos. Aplicando el coeficiente de correlación tetracórico, se realizó un análisis factorial. La consistencia interna se valoró mediante el coeficiente alfa de Crombach. Finalmente, se valoró la asociación cruda y ajustada de cada factor identificado con la odds de haber sufrido un accidente. Resultados: Tras descartar 8 circunstancias, las restantes se agruparon en tres factores: el primero incluyó diez circunstancias de elevada prevalencia y explicó el 31,9% de la variabilidad total. Los otros dos factores, incluyeron cinco circunstancias cada uno que explicaron respectivamente, el 15,2% y el 12,5% de la variabilidad. Los coeficientes alfa de Crombach oscilaron entre 0,816 y 0,553. Cuando se ajustó por la edad, el sexo, los años de antigüedad del permiso y la intensidad de exposición, la puntuación más fuertemente asociada a la accidentalidad fue la del primer factor (OR=1,51: IC95% 1,25-1,85.

    Atherosclerosis is a disease which develops very gradually over decades. Under the influence of modifiable cardiovascular risk factors, such as blood pressure, LDL-cholesterol level, smoking or lifestyle, clinical symptoms of atherosclerosis manifest more or less early in life. When cardiovascular risk factors accumulate, the risk of having a cardiovascular event increases and the benefits of prevention measures are greater. This article summarizes existing strategies for controlling modifiable cardiovascular risk factors in primary prevention. The physician can rely on an interprofessional network of cardiovascular prevention. Managing risk factors while respecting the autonomy and priorities of the patient will bring the greatest benefit.

  3. Cardiovascular: radioisotopic angiocardiography

    Radioisotopic angiocardiography, performed after the intravenous injection of 99 /sup m/Tc-labeled pertechnetate or albumin, is a simple, rapid, and safe procedure which permits identification and physiologic assessment of a wide variety of congenital and acquired cardiovascular lesions in infants and children. These include atrial and ventricular septal defect, tetralogy of Fallot, pulmonic stenosis, aortopulmonary window, transposition of the great vessels, valvular stenosis and/or insufficiency, myocardial lesions, and lesions of the great vessels. The simplicity of the procedure lends itself to repeated measurements to assess the effects of therapy or to follow the course of the disease. A wide spectrum of congenital and acquired cardiovascular diseases have been studied which have particular application to the pediatric age group. (auth)

    The cardiovascular manifestations of alkaptonuria relate to deposition of ochronotic pigment within heart valves, endocardium, aortic intima and coronary arteries. We assessed 16 individuals with alkaptonuria for cardiovascular disease, including full electrocardiographic and echocardiographic assessment. The self reported prevalence of valvular heart disease and coronary artery disease was low. There was a significant burden of previously undiagnosed aortic valve disease, reaching a prevalence of over 40% by the fifth decade of life. The aortic valve disease was found to increase in both prevalence and severity with advancing age. In contrast to previous reports, we did not find a significant burden of mitral valve disease or coronary artery disease. These findings are important for the clinical follow-up of patients with alkaptonuria and suggest a role for echocardiographic surveillance of patients above 40 years old.

  5. Prodrugs in Cardiovascular Therapy

    Full Text Available Prodrugs are biologically inactive derivatives of an active drug intended to solve certain problems of the parent drug such as toxicity, instability, minimal solubility and non-targeting capabilities. The majority of drugs for cardiovascular diseases undergo firstpass metabolism, resulting in drug inactivation and generation of toxic metabolites, which makes them appealing targets for prodrug design. Since prodrugs undergo a chemical reaction to form the parent drug once inside the body, this makes them very effective in controlling the release of a variety of compounds to the targeted site. This review will provide the reader with an insight on the latest developments of prodrugs that are available for treating a variety of cardiovascular diseases. In addition, we will focus on several drug delivery methodologies that have merged with the prodrug approach to provide enhanced target specificity and controlled drug release with minimal side effects.

    Full Text Available Cardiovascular disease is the leading cause of death for both men and women worldwide. Much emphasis has been placed on the primary and secondary prevention of cardiovascular disease. While depression and anxiety increase the risk of developing cardiovascular disease, cardiovascular disease also increases the risk of developing anxiety and depression. Thus, promoting optimal mental health may be important for both primary and secondary prevention of cardiovascular disease. Like lowering blood pressure, lipids, and body weight, lowering anger and hostility and improving depression and anxiety may also be an important intervention in preventive cardiology. As we strive to further improve cardiovascular outcomes, the next bridge to cross may be one of offering patients nonpharmacologic means for combating daily mental stress and promoting mental health, such as yoga and pranayama. Indeed, the best preventive cardiovascular medicine may be a blend of both Western and Eastern medicine.

    Molecular imaging strives to visualize processes in living subjects at the molecular level. Monitoring biochemical processes at this level will allow us to directly track biological processes and signaling events that lead to pathophysiological abnormalities, and help make personalized medicine a reality by allowing evaluation of therapeutic efficacies on an individual basis. Although most molecular imaging techniques emerged from the field of oncology, they have now gradually gained acceptance by the cardiovascular community. Hence, the availability of dedicated high-resolution small animal imaging systems and specific targeting imaging probes is now enhancing our understanding of cardiovascular diseases and expediting the development of newer therapies. Examples include imaging approaches to evaluate and track the progress of recent genetic and cellular therapies for treatment of myocardial ischemia. Other areas include in vivo monitoring of such key molecular processes as angiogenesis and apoptosis. Cardiovascular molecular imaging is already an important research tool in preclinical experiments. The challenge that lies ahead is to implement these techniques into the clinics so that they may help fulfill the promise of molecular therapies and personalized medicine, as well as to resolve disappointments and controversies surrounding the field

    Pregnancy causes significant metabolic and hemodynamic changes in a woman’s physiology to allow for fetal growth. The inability to adapt to these changes might result in the development of hypertensive disorders of pregnancy (hypertension, preeclampsia or eclampsia), gestational diabetes and preterm birth. Contrary to previous beliefs these complications are not limited to the pregnancy period and may leave permanent vascular and metabolic damage. There is in addition, a direct association between these disorders and increased risk of future cardiovascular disease (CVD, including hypertension, ischemic heart disease, heart failure and stroke) and diabetes mellitus. Despite abundant evidence of this association, women who present with these complications of pregnancy do not receive adequate postpartum follow up and counseling regarding their increased risk of future CVD. The postpartum period in these women represents a unique opportunity to intervene with lifestyle modifications designed to reduce the development of premature cardiovascular complications. In some cases it allows early diagnosis and treatment of chronic hypertension or diabetes mellitus. The awareness of this relationship is growing in the medical community, especially among obstetricians and primary care physicians, who play a pivotal role in detecting these complications and assuring appropriate follow up.

Despite abundant evidence of this association, women who present with these complications of pregnancy do not receive adequate postpartum follow up and counseling regarding their increased risk of future CVD. The postpartum period in these women represents a unique opportunity to intervene with lifestyle modifications designed to reduce the development of premature cardiovascular complications. In some cases it allows early diagnosis and treatment of chronic hypertension or diabetes mellitus. The awareness of this relationship is growing in the medical community, especially among obstetricians and primary care physicians, who play a pivotal role in detecting these complications and assuring appropriate follow up.

    Cardiovascular diseases represent a widespread heterogeneous group of conditions that have significant morbidity and mortality. The various diseases and their treatments can have an impact upon the periodontium and the delivery of periodontal care. In this paper we consider three main topics and explore their relationship to the periodontist and the provision of periodontal treatment. The areas reviewed include the effect of cardiovascular drugs on the periodontium and management of patients with periodontal diseases; the risk of infective endocarditis arising from periodontal procedures; the inter-relationship between periodontal disease and coronary artery disease. Calcium-channel blockers and beta-adrenoceptor blockers cause gingival overgrowth and tooth demineralisation, respectively. Evidence suggests that stopping anticoagulant therapy prior to periodontal procedures is putting patients at a greater risk of thromboembolic disorders compared to the risk of prolonged bleeding. The relationship between dentistry and infective endocarditis remains a controversial issue. It would appear that spontaneous bacteraemia arising from a patient's oral hygiene practices is more likely to be the cause of endocarditis than one-off periodontal procedures. The efficacy of antibiotic prophylaxis is uncertain (and unlikely to be proven), and the risk of death from penicillin appears to be greater than the risk of death arising from infective endocarditis. Finally, the association between periodontal disease and coronary artery disease has been explored and there seem to be many issues with respect to data handling interpretation. Many putative mechanisms have been suggested; however, these only further highlight the need for intervention studies.

    extras a la homeostasis cardiovascular en la presencia del síndrome coronario aguda (SCA OBJETIVO: Investigar si un diagnóstico clínico estandarizado de SAOS, en pacientes con SCA, predice el riesgo de eventos cardiovasculares durante la hospitalización. MÉTODOS: En un estudio de cohorte prospectivo, un grupo de 200 pacientes con diagnóstico de SCA elecido entre Septiembre de 2005 y Noviembre de 2007, fueron estratificados por el Cuestionario de Berlín (CB para el riesgo de SAOS (alto o bajo riesgo. Se probó si el subgrupo de alto riesgo para SAOS presenta mayor tendencia a eventos cardiovasculares. El endpoint primario evaluado fue un desenlace conformado por muerte cardiovascular, eventos cardíacos isquémicos recurrentes, edema pulmonar agudo y accidente vascular cerebral durante la hospitalización. RESULTADOS: Noventa y cuatro (47% de los pacientes identificados por el CB presentaban sospecha de SAOS. Alto riesgo para SAOS estaba asociado con una mortalidad más elevada, aunque sin diferencia estadística (4,25% vs 0,94%; p=0,189, pero con una estadísticamente significativa mayor incidencia de desenlace conformada por eventos cardiovasculares (18,08% vs 6,6%; p=0,016.

    Cardiovascular diseases (CVDs) are the leading cause of death among adult women in many parts of India and a major cause of morbidity. In some parts of the world, gender inequities have been observed in cardiovascular healthcare and cardiovascular outcomes. The authors discuss the data for potential disparities in cardiovascular healthcare for women in India. Data on cardiovascular healthcare provision and CVD outcomes among women in India are generally lacking. The little available data suggest that women in rural areas, younger women and girl children with CVD are less likely to receive appropriate management than men, with this disparity most apparent in those of lower socioeconomic status and education. However, there is a particular lack of information about the prevention and management of atherosclerotic heart disease in women from a range of communities that comprise the extremely diverse population of India.

    Cardiovascular diseases (CVDs) are the number one cause of mortality worldwide. Low-density lipoprotein (LDL) cholesterol is a well-known risk factor of CVD which increases after the intake of saturated fatty acids (SFA). Cheese is a dietary product commonly consumed in Western countries and known...... to contain high amounts of SFA. However, cheese also contributes with several nutrients in the diet such as essential amino acids and calcium. The aim of this thesis was to examine the effect of cheese intake on CVD risk through evidence from both observational, intervention and explorative studies....... By reviewing results from published observational studies it was concluded that cheese does not seem to increase CVD risk, despite of the high SFA content of most cheeses. A human cross-over intervention study was conducted with the purpose of investigating the effect of hard cheese intake on risk markers...

  4. Assessment of cardiovascular risk.

    Atherosclerotic cardiovascular disease (CVD) is the most common cause of death worldwide. Usually atherosclerosis is caused by the combined effects of multiple risk factors. For this reason, most guidelines on the prevention of CVD stress the assessment of total CVD risk. The most intensive risk factor modification can then be directed towards the individuals who will derive the greatest benefit. To assist the clinician in calculating the effects of these multiple interacting risk factors, a number of risk estimation systems have been developed. This review address several issues regarding total CVD risk assessment: Why should total CVD risk be assessed? What risk estimation systems are available? How well do these systems estimate risk? What are the advantages and disadvantages of the current systems? What are the current limitations of risk estimation systems and how can they be resolved? What new developments have occurred in CVD risk estimation?

En el presente estudio se ha realizado un análisis factorial confirmatorio sobre una muestra de 1242 sujetos en tratamiento por adicción, y se ha estudiado la fiabilidad de las escalas y su validez predictiva sobre variables de salud y estrés percibido. El estudio factorial mostró una adecuada validez de constructo y todas las escalas han mostrado adecuada fiabilidad, salvo la de locus de control, con sólo tres ítems. Varias escalas muestran correlaciones de gran magnitud con estrés percibido, calidad de vida relacionada con la salud y riesgo de mala salud mental. Destaca la capacidad predictiva de la escala de optimismo sobre estas tres variables, siendo probablemente la menos estudiada en relación a la adicción. El tratamiento efectivo de las drogodependencias está íntimamente ligado a la evaluación y posible intervención sobre características psicológicas individuales que pueden condicionar el resultado terapéutico. Por ello, es preciso contar con instrumentos de evaluación fiables y válidos que permitan delimitar las características personales, fortalezas y debilidades, de las personas que van a realizar un tratamiento. El VIP parece ser una herramienta útil en la evaluación psicológica, en la medida en que proporciona, en una sola administración, datos sobre un buen número de variables psicológicas, es una prueba gratuita, de libre disposición para los clínicos e investigadores y fácil corrección e interpretación.

    Cardiovascular diseases are the leading cause of death in industrialized countries. Their incidence increases, apparently, as a, function of technological progress so that in the future they may become a major public health problem in developing countries too. Early diagnosis and prevention are the tools best suited to curb such an alarming trend, but our knowledge of these topics is unsatisfactory, Valuable information would be obtained through a systematic investigation of trace elements in relation to cardiovascular function and to various types of cardiovascular diseases. Such studies would provide clues to the following questions: 1. Why does the incidence and type of cardiovascular disease differ from one country to another? May this be related to differences in tissue mineral concentrations among various population groups? 2. Which trace elements if any are beneficial to cardiovascular health, and which are harmful ones that may act as aetiological agents for some cardiovascular diseases? 3. Is it possible to utilize measurements of mineral element concentration for diagnostic purposes in cardiovascular disease? (author)

    BACKGROUND: Mortality from cardiovascular diseases is substantially higher in central and eastern Europe than in the west. After the fall of communism, these countries have undergone radical changes in their political, social, and economic environments but little is known about the impact of these changes on health behaviours or risk factors. Data from the Czech Republic, a country whose mortality rates from cardiovascular diseases are among the highest, were analysed in this report. OBJECTIVES: To examine the trends in cardiovascular risk factors in Czech population over the last decade during which a major and sudden change of the political and social system occurred in 1989, and whether the trends differed in relation to age and educational group. DESIGN AND SETTING: Data from three cross sectional surveys conducted in 1985, 1988, and 1992 as a part of the MONICA project were analysed. The surveys examined random samples of men and women aged 25-64 in six Czech districts and measured the following risk factors: smoking, blood pressure, body mass index (BMI), and total and high density lipoprotein (HDL) cholesterol. RESULTS: The numbers of subjects (response rate) examined were 2573 (84%) in 1985, 2769 (87%) in 1988, and 2353 (73%) in 1992. Total cholesterol and body mass index increased between 1985 and 1988 and decreased between 1988 and 1992. The prevalence of smoking was declining slightly in men between 1985 and 1992 but remained stable in women. There were only small changes in blood pressure. The decline in cholesterol and BMI in 1988-92 may be related to changes in foods consumption after the price deregulation in 1991. An improvement in risk profile was more pronounced in younger age groups, and the declines in cholesterol and obesity were substantially larger in men and women with higher education. By contrast, there was an increase in smoking in women educated only to primary level. CONCLUSION: Substantial changes in cholesterol, obesity, and women

    The practice of contrast-enhanced magnetic resonance angiography (CEMRA) has changed significantly in the span of a decade. Concerns regarding gadolinium (Gd)-associated nephrogenic systemic fibrosis in those with severely impaired renal function spurred developments in low-dose CEMRA and non-contrast MRA as well as efforts to seek alternative MR contrast agents. Originally developed for MR imaging use, ferumoxytol (an ultra-small superparamagnetic iron oxide nanoparticle), is currently approved by the US Food and Drug Administration for the treatment of iron deficiency anaemia in adults with renal disease. Since its clinical availability in 2009, there has been rising interest in the scientific and clinical use of ferumoxytol as an MR contrast agent. The unique physicochemical and pharmacokinetic properties of ferumoxytol, including its long intravascular half-life and high r 1 relaxivity, support a spectrum of MRI applications beyond the scope of Gd-based contrast agents. Moreover, whereas Gd is not found in biological systems, iron is essential for normal metabolism, and nutritional iron deficiency poses major public health challenges worldwide. Once the carbohydrate shell of ferumoxytol is degraded, the elemental iron at its core is incorporated into the reticuloendothelial system. These considerations position ferumoxytol as a potential game changer in the field of CEMRA and MRI. In this paper, we aim to summarise our experience with the cardiovascular applications of ferumoxytol and provide a brief synopsis of ongoing investigations on ferumoxytol-enhanced MR applications.

    Approximately one out of every five patients with cardiovascular disease (CVD) suffers from major depressive disorder (MDD). Both MDD and depressive symptoms are risk factors for CVD incidence, severity and outcomes. Great progress has been made in understanding potential mediators between MDD and CVD, particularly focusing on health behaviors. Investigators have also made considerable strides in the diagnosis and treatment of depression among patients with CVD. At the same time, many research questions remain. In what settings is depression screening most effective for patients with CVD? What is the optimal screening frequency? Which therapies are safe and effective? How can we better integrate the care of mental health conditions with that of CVD? How do we motivate depressed patients to change health behaviors? What technological tools can we use to improve care for depression? Gaining a more thorough understanding of the links between MDD and heart disease, and how best to diagnose and treat depression among these patients, has the potential to substantially reduce morbidity and mortality from CVD.

    A symposium of eight short but complete papers giving an overview of interventional radiology is presented. Organized by Dr. William Casarella, this symposium is certainly the most current review of the subject available. This year's cardiovascular section is again heavily weighted toward interventional radiology. Abrams and Doubilet's article on the underutilization of angioplasty is important because it describes the cost effectiveness of this method. Most health planners, right or wrong, have complained about overutilization of diagnostic radiology procedures. In general, the opposite is true for interventional procedures - they are underutilized. If the authors draw the attention of their hospital administrators to these approaches and also produce the data on long-term follow-up for our medical colleagues, interventional radiology may realize its full potential. Articles on cardiac magnetic resonance imaging are beginning to appear and this technique seems to have great potential. An important article, which is the first prospective study comparing lung scintigraphy and pulmonary angiography in the diagnosis of pulmonary embolism, supports the increased use of pulmonary angiography. Finally, an article on complications of percutaneous biliary drainage provokes some discussion of its value for routine preoperative use

    Turner syndrome is a relatively common genetic disorder of female development, characterized by partial or complete absence of an X chromosome, with a variable clinical presentation. Congenital or acquired cardiovascular disease is highly prevalent and a major cause of early death in this syndrome. The most feared complication is aortic dissection, which can occur at a very young age and requires careful assessment of its risk factors. A systematic literature search identified sixty relevant publications. These were reviewed with regard to the increased risk of cardiovascular disease in women with Turner syndrome, especially in pregnancy. The most common congenital cardiovascular defects are presented and illustrated with appropriate iconography. The current recommendations regarding the screening and monitoring of cardiovascular disease in these patients are discussed. Copyright © 2018 Sociedade Portuguesa de Cardiologia.

  5. Environmental Factors and Cardiovascular Diseases

    Full Text Available Epidemiological and clinical observations have led to the hypothesis that the risk of developing cardiovascular diseases is influenced not only by genetic, lifestyle and major risk factors, but also by environmental factors. Environmental factors are considered key determinants of cardiovascular diseases. Although lifestyle choices such as smoking, diet, and exercise are viewed as major environmental influences, the contribution of pollutants and environmental chemicals is less clear. Accumulating evidence suggests that exposure to physically and chemical pollutants could elevate the risk of cardiovascular diseases. Many epidemiological studies report that exposure to physically, biologically and socio-cultural environmental factors are associated with an increase in cardiovascular mortality. Relationships between environmental factors and coronary arter disease, arhythmias, and cardiomyopathies have been reported. Exposures to arsenic, lead, cadmium, pollutant gases, solvents, and pesticides have also been linked to increased incidence of cardiovascular disease. In this paper, I review that relationships between exposure to physically, chemical, biologically and socio-cultural environmental factors and cardiovascular diseases.

    Transition metal ion-mediated oxidation is a commonly used model system for studies of the chemical, structural, and functional modifications of low-density lipoprotein (LDL). The physiological relevance of studies using free metal ions is unclear and has led to an exploration of free metal ion-independent mechanisms of oxidation. We and others have investigated the role of human ceruloplasmin (Cp) in oxidative processes because it the principal copper-containing protein in serum. There is an abundance of epidemiological data that suggests that serum Cp may be an important risk factor predicting myocardial infarction and cardiovascular disease. Biochemical studies have shown that Cp is a potent catalyst of LDL oxidation in vitro. The pro-oxidant activity of Cp requires an intact structure, and a single copper atom at the surface of the protein, near His(426), is required for LDL oxidation. Under conditions where inhibitory protein (such as albumin) is present, LDL oxidation by Cp is optimal in the presence of superoxide, which reduces the surface copper atom of Cp. Cultured vascular endothelial and smooth muscle cells also oxidize LDL in the presence of Cp. Superoxide release by these cells is a critical factor regulating the rate of oxidation. Cultured monocytic cells, when activated by zymosan, can oxidize LDL, but these cells are unique in their secretion of Cp. Inhibitor studies using Cp-specific antibodies and antisense oligonucleotides show that Cp is a major contributor to LDL oxidation by these cells. The role of Cp in lipoprotein oxidation and atherosclerotic lesion progression in vivo has not been directly assessed and is an important area for future studies.

  7. Obesity and Cardiovascular Disease.

    The prevalence of obesity has increased worldwide over the past few decades. In 2013, the prevalence of obesity exceeded the 50% of the adult population in some countries from Oceania, North Africa, and Middle East. Lower but still alarmingly high prevalence was observed in North America (≈30%) and in Western Europe (≈20%). These figures are of serious concern because of the strong link between obesity and disease. In the present review, we summarize the current evidence on the relationship of obesity with cardiovascular disease (CVD), discussing how both the degree and the duration of obesity affect CVD. Although in the general population, obesity and, especially, severe obesity are consistently and strongly related with higher risk of CVD incidence and mortality, the one-size-fits-all approach should not be used with obesity. There are relevant factors largely affecting the CVD prognosis of obese individuals. In this context, we thoroughly discuss important concepts such as the fat-but-fit paradigm, the metabolically healthy but obese (MHO) phenotype and the obesity paradox in patients with CVD. About the MHO phenotype and its CVD prognosis, available data have provided mixed findings, what could be partially because of the adjustment or not for key confounders such as cardiorespiratory fitness, and to the lack of consensus on the MHO definition. In the present review, we propose a scientifically based harmonized definition of MHO, which will hopefully contribute to more comparable data in the future and a better understanding on the MHO subgroup and its CVD prognosis. © 2016 American Heart Association, Inc.

El objetivo del estudio es validar el cuestionario de frecuencia de consumo de alimentos CDCFFQ, que es una adaptación de otro cuestionario, para estudiar la alimentación de la población adulta de Canarias. Métodos: El cuestionario CDC-FFQ fue administrado a 1.067 personas de la población general (PG y a 106 estudiantes universitarios (EU, de 19 a 30 años. El segundo grupo fue encuestado también sobre tres recordatorios de 24 horas. Se comparan los nutrientes según CDC-FFQ en PG y EU. Se estiman las correlaciones entre CDC-FFQ y los recordatorios para nutrientes y grupos de alimentos, y la concordancia de consumos de nutrientes y grupos de alimentos en los quintiles extremos, para los estudiantes universitarios. Resultados: Los valores medios entre nutrientes del CDC-FFQ entre PG, EU y población general con estudios universitarios no mostraron diferencias significativas excepto para la vitamina B12 (p=0.004 y la vitamina D (p=0,005. Entre el CDC-FFQ y la media de los tres recordatorios se obtuvieron correlaciones en el rango de 0,202-0,601 entre nutrientes ajustados por calorías consumidas para los estudiantes universitarios. Por grupos de alimentos las correlaciones oscilaron para CDC-FFQ y los recordatorios entre 0,243- 0,542. La concordancia de nutrientes osciló entre 39% y 100% y para grupos de alimentos entre 41% y 100%. Conclusiones: El cuestionario CDC-FFQ resulta válido para clasificar a los sujetos en los rangos relativos de su nivel de ingesta de alimentos y nutrientes, por lo que podría ser útil en estudios epidemiológicos con valoración de dieta en población canaria adulta.

  19. Lack of supportive leadership behavior predicts suboptimal self-rated health independent of job strain after 10 years of follow-up: findings from the population-based MONICA/KORA study.

    Emerging cross-sectional research has identified lack of supportive leadership behavior (SLB) as a risk factor for workforce health. However, prospective evidence is hitherto lacking. SLB denotes support in difficult situations, recognition and feedback on work tasks. This study aims to determine the effect of SLB on suboptimal self-rated health (SRH) after 10 years considering potential moderators such as ages, sex, occupation and job strain. The sample included 884 employed participants drawn from the population-based prospective MONICA/KORA Study. SLB, SRH, as well as job strain were assessed by questionnaire. Logistic regressions estimated odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for the effect of SLB at baseline on suboptimal SRH at follow-up. Analyses were adjusted for age, gender, lifestyle (alcohol, smoking, physical activity), socioeconomic status as well as for SRH and job strain at baseline. Lack of SLB was associated with suboptimal SRH at baseline [OR 2.00, (95% CI 1.19-3.46)] and at follow-up [OR 2.33, (95% CI 1.40-3.89)]. Additional adjustment for job strain did not substantially alter this association [OR 2.06, (95% CI 1.20-3.52)]. However, interactions between SLB and job strain as well as gender became evident, indicating moderating influences on the association between SLB and SRH. Lack of supportive leadership was associated with suboptimal SRH at 10 years' follow-up in men, even if SRH at baseline and other risk factors were taken into account. This effect is likely to be moderated by job strain.

    With the aim of assessment of 10 year risk of myocardial infarction (MI) development in men in dependence on stress at work place and in the family in a framework of the WHO program "MONICA-PSYCHOSOCIAL" we examined random representative sample of men (n=657) aged 25-64 years inhabitants of one of districts in Novosibirsk. During 10 years (1994-2004) we registered all cases of MI. For assessment of relative risk of MI development we used COX proportional regression model. Among men with first MI 47.4% had high level of stress in the family and 57.9% were subjected to stress at work place. Five and 10 year risk of MI in men with high test levels of stress at home and work place was 2-5 times greater than in those without. Among men subjected to stress in the family MI risk was the highest at age 55-64 years, while permanent stressful situations at work place were more common in age group 45-54 years. Among men with high levels of stress in the family and at work place higher rate of MI development was observed in widowers, divorced men with incomplete high or elementary education, heavy or moderate manual labor workers, and pensioners. The results indicate that critical life events as well as chronic stressful influences increase risk of MI among men aged 25-64 years. The group of greatest risk - middle and old age persons who are less protected against social, political and economical disbalance in the society.

    2013-01-01

    In addition to its effects on reproductive health, it is now well recognized that polycystic ovary syndrome (PCOS) is a metabolic disorder, characterized by decreased insulin sensitivity which leads to an excess lifetime risk of type 2 diabetes and cardiovascular disease. PCOS patients are often obese, hypertensive, dyslipidemic and insulin resistant; they have obstructive sleep apnea and have been reported to have higher aldosterone levels in comparison to normal healthy controls. These are all components of an adverse cardiovascular risk profile. Many studies exploring subclinical atherosclerosis using different methods (flow-mediated dilatation, intima media thickness, arterial stiffness, coronary artery calcification) as well as assessing circulating cardiovascular risk markers, point toward an increased cardiovascular risk and early atherogenesis in PCOS. The risk and early features of subclinical atherosclerosis can be reversed by non-medical (normalization of weight, healthy lifestyle) and medical (metformin, thiazolidinediones, spironolactone, and statins) interventions. However, the long-term risk for cardiovascular morbidity and mortality as well as the clinical significance of different interventions still need to be properly addressed in a large prospective study.

    Women with cardiovascular disease are treated less aggressively than men. The reasons for this disparity are unclear. Pharmaceutical advertisements may influence physician practices and patient care. To determine if female and male patients are equally likely to be featured in cardiovascular advertisements. We examined all cardiovascular advertisements from US editions of general medical and cardiovascular journals published between 1 January 1996 and 30 June 1998. For each unique advertisement, we recorded the total number of journal appearances and the number of appearances in journals' premium positions. We noted the gender, age, race and role of both the primary figure and the majority of people featured in the advertisement. Nine hundred and nineteen unique cardiovascular advertisements were identified of which 254 depicted a patient as the primary figure. A total of 20%[95% confidence interval (CI) 15.3-25.5%] of these advertisements portrayed a female patient, while 80% (95% CI 74.5-84.7%) depicted a male patient, P advertisements appeared 249 times (13.3%; 95% CI 8.6-18.9%) while male patient advertisements appeared 1618 times (86.7%; 95% CI 81.1-91.4%), P advertisements also had significantly fewer mean appearances than male patient advertisements in journals' premium positions (0.82 vs. 1.99, P=0.02). Similar results were seen when the advertisements were analysed according to predominant gender. Despite increasing emphasis on cardiovascular disease in women, significant under-representation of female patients exists in cardiovascular advertisements. Physicians should be cognizant of this gender bias.

    Abstract Peroxisome proliferator-activated receptors (PPARs) belong to the nuclear hormone-receptor superfamily. Originally cloned in 1990, PPARs were found to be mediators of pharmacologic agents that induce hepatocyte peroxisome proliferation. PPARs also are expressed in cells of the cardiovascular system. PPARγ appears to be highly expressed during atherosclerotic lesion formation, suggesting that increased PPARγ expression may be a vascular compensatory response. Also, ligand-activated PPARγ decreases the inflammatory response in cardiovascular cells, particularly in endothelial cells. PPARα, similar to PPARγ, also has pleiotropic effects in the cardiovascular system, including antiinflammatory and antiatherosclerotic properties. PPARα activation inhibits vascular smooth muscle proinflammatory responses, attenuating the development of atherosclerosis. However, PPARδ overexpression may lead to elevated macrophage inflammation and atherosclerosis. Conversely, PPARδ ligands are shown to attenuate the pathogenesis of atherosclerosis by improving endothelial cell proliferation and survival while decreasing endothelial cell inflammation and vascular smooth muscle cell proliferation. Furthermore, the administration of PPAR ligands in the form of TZDs and fibrates has been disappointing in terms of markedly reducing cardiovascular events in the clinical setting. Therefore, a better understanding of PPAR-dependent and -independent signaling will provide the foundation for future research on the role of PPARs in human cardiovascular biology. Antioxid.

    Abstract Computational models of many aspects of the mammalian cardiovascular circulation have been developed. Indeed, along with orthopaedics, this area of physiology is one that has attracted much interest from engineers, presumably because the equations governing blood flow in the vascular system are well understood and can be solved with well‐established numerical techniques. Unfortunately, there have been only a few attempts to create a comprehensive public domain resource for cardiovascular researchers. In this paper we propose a roadmap for developing an open source cardiovascular circulation model. The model should be registered to the musculo‐skeletal system. The computational infrastructure for the cardiovascular model should provide for near real‐time computation of blood flow and pressure in all parts of the body. The model should deal with vascular beds in all tissues, and the computational infrastructure for the model should provide links into CellML models of cell function and tissue function. In this work we review the literature associated with 1D blood flow modelling in the cardiovascular system, discuss model encoding standards, software and a model repository. We then describe the coordinate systems used to define the vascular geometry, derive the equations and discuss the implementation of these coupled equations in the open source computational software OpenCMISS. Finally, some preliminary results are presented and plans outlined for the next steps in the development of the model, the computational software and the graphical user interface for accessing the model.

    Sibutramine is an anorectic that has been banned since 2010 due to cardiovascular safety issues. However, counterfeit drugs or slimming products that include sibutramine are still available in the market. It has been reported that illegal sibutramine-contained pharmaceutical products induce cardiovascular crisis. However, the mechanism underlying sibutramine-induced cardiovascular adverse effect has not been fully evaluated yet. In this study, we performed cardiovascular safety pharmacology studies of sibutramine systemically using by hERG channel inhibition, action potential duration, and telemetry assays. Sibutramine inhibited hERG channel current of HEK293 cells with an IC50 of 3.92 μM in patch clamp assay and increased the heart rate and blood pressure (76 Δbpm in heart rate and 51 ΔmmHg in blood pressure) in beagle dogs at a dose of 30 mg/kg (per oral), while it shortened action potential duration (at 10 μM and 30 μM, resulted in 15% and 29% decreases in APD50, and 9% and 17% decreases in APD90, respectively) in the Purkinje fibers of rabbits and had no effects on the QTc interval in beagle dogs. These results suggest that sibutramine has a considerable adverse effect on the cardiovascular system and may contribute to accurate drug safety regulation.

  7. The cardiovascular system after exercise

    Recovery from exercise refers to the time period between the end of a bout of exercise and the subsequent return to a resting or recovered state. It also refers to specific physiological processes or states occurring after exercise that are distinct from the physiology of either the exercising or the resting states. In this context, recovery of the cardiovascular system after exercise occurs across a period of minutes to hours, during which many characteristics of the system, even how it is controlled, change over time. Some of these changes may be necessary for long-term adaptation to exercise training, yet some can lead to cardiovascular instability during recovery. Furthermore, some of these changes may provide insight into when the cardiovascular system has recovered from prior training and is physiologically ready for additional training stress. This review focuses on the most consistently observed hemodynamic adjustments and the underlying causes that drive cardiovascular recovery and will highlight how they differ following resistance and aerobic exercise. Primary emphasis will be placed on the hypotensive effect of aerobic and resistance exercise and associated mechanisms that have clinical relevance, but if left unchecked, can progress to symptomatic hypotension and syncope. Finally, we focus on the practical application of this information to strategies to maximize the benefits of cardiovascular recovery, or minimize the vulnerabilities of this state. We will explore appropriate field measures, and discuss to what extent these can guide an athlete’s training. PMID:28153943

    After the first cases of primary aldosteronism were described and characterized by Conn, a substantial body of experimental and clinical evidence about the long-term effects of excess aldosterone on the cardiovascular system was gathered over the last 5 decades. The prevalence of primary aldosteronism varies considerably between different studies among hypertensive patients, depending on patient selection, the used diagnostic methods, and the severity of hypertension. Prevalence rates vary from 4.6 to 16.6% in those studies in which confirmatory tests to diagnose primary aldosteronism were used. There is also growing evidence indicating that prolonged exposure to elevated aldosterone concentrations is associated with target organ damage in the heart, kidney, and arterial wall, and high cardiovascular risk in patients with primary aldosteronism. Therefore, the aim of treatment should not be confined to BP normalization and hypokalemia correction, but rather should focus on restoring the deleterious effects of excess aldosterone on the cardiovascular system. Current evidence convincingly demonstrates that both surgical and medical treatment strategies beneficially affect cardiovascular outcomes and mortality in the long term. Further studies can be expected to provide better insight into the relationship between cardiovascular risk and complications and the genetic background of primary aldosteronism. © Georg Thieme Verlag KG Stuttgart · New York.

    Chronic obstructive pulmonary disease (COPD) and chronic cardiovascular disease, such as coronary artery disease, congestive heart failure, and cardiac arrhythmias, have a strong influence on each other, and systemic inflammation has been considered as the main linkage between them. On the other hand, airflow limitation may markedly affect lung mechanics in terms of static and dynamic hyperinflation, especially in pulmonary emphysema, and they can in turn influence cardiac performance as well. Skeletal mass depletion, which is a common feature in COPD especially in pulmonary emphysema patients, may have also a role in cardiovascular function of these patients, irrespective of lung damage. We reviewed the emerging evidence that highlights the role of lung mechanics and muscle mass impairment on ventricular volumes, stroke volume, and stroke work at rest and on exercise in the presence of pulmonary emphysema. Patients with emphysema may differ among COPD population even in terms of cardiovascular function.

    Air pollution is composed of particulate matter (PM) and gaseous pollutants, such as nitrogen dioxide and ozone. PM is classified according to size into coarse particles (PM 10 ), fine particles (PM 2.5 ) and ultrafine particles. We aim to provide an original review of the scientific evidence from epidemiological and experimental studies examining the cardiovascular effects of outdoor air pollution. Pooled epidemiological studies reported that a 10μg/m 3 increase in long-term exposure to PM 2.5 was associated with an 11% increase in cardiovascular mortality. Increased cardiovascular mortality was also related to long-term and short-term exposure to nitrogen dioxide. Exposure to air pollution and road traffic was associated with an increased risk of arteriosclerosis, as shown by premature aortic and coronary calcification. Short-term increases in air pollution were associated with an increased risk of myocardial infarction, stroke and acute heart failure. The risk was increased even when pollutant concentrations were below European standards. Reinforcing the evidence from epidemiological studies, numerous experimental studies demonstrated that air pollution promotes a systemic vascular oxidative stress reaction. Radical oxygen species induce endothelial dysfunction, monocyte activation and some proatherogenic changes in lipoproteins, which initiate plaque formation. Furthermore, air pollution favours thrombus formation, because of an increase in coagulation factors and platelet activation. Experimental studies also indicate that some pollutants have more harmful cardiovascular effects, such as combustion-derived PM 2.5 and ultrafine particles. Air pollution is a major contributor to cardiovascular diseases. Promotion of safer air quality appears to be a new challenge in cardiovascular disease prevention.

    This study examined the prevalence of airline pilots who have an excessive cardiovascular disease (CVD) risk score according to the New Zealand Guideline Group (NZGG) Framingham-based Risk Chart and describes their cardiovascular risk assessment and investigations. A cross-sectional study was performed among 856 pilots employed in an Oceania based airline. Pilots with elevated CVD risk that had been previously evaluated at various times over the previous 19 yr were reviewed retrospectively from the airline's medical records, and the subsequent cardiovascular investigations were then described. There were 30 (3.5%) pilots who were found to have 5-yr CVD risk score of 10-15% or higher. Of the 29 pilots who had complete cardiac investigations data, 26 pilots underwent exercise electrocardiography (ECG), 2 pilots progressed directly to coronary angiograms and 1 pilot with abnormal echocardiogram was not examined further. Of the 26 pilots, 7 had positive or borderline exercise tests, all of whom subsequently had angiograms. One patient with a negative exercise test also had a coronary angiogram. Of the 9 patients who had coronary angiograms as a consequence of screening, 5 had significant disease that required treatment and 4 had either trivial disease or normal coronary arteries. The current approach to investigate excessive cardiovascular risk in pilots relies heavily on exercise electrocardiograms as a diagnostic test, and may not be optimal either to detect disease or to protect pilots from unnecessary invasive procedures. A more comprehensive and accurate cardiac investigation algorithm to assess excessive CVD risk in pilots is required.

The use of animal models have contributed to increase our knowledge, providing new approaches focused to improve the diagnostic and the treatment of these pathologies. Several models have been developed to address cardiovascular complications, including atherothrombotic and cardiac diseases, and the same pathology have been successfully recreated in different species, including small and big animal models of disease. However, genetic and environmental factors play a significant role in cardiovascular pathophysiology, making difficult to match a particular disease, with a single experimental model. Therefore, no exclusive method perfectly recreates the human complication, and depending on the model, additional considerations of cost, infrastructure, and the requirement for specialized personnel, should also have in mind. Considering all these facts, and depending on the budgets available, models should be selected that best reproduce the disease being investigated. Here we will describe models of atherothrombotic diseases, including expanding and occlusive animal models, as well as models of heart failure.

    Despite life-style advice and the prescription of cholesterol-lowering and anti-thrombotic drugs, cardiovascular diseases are still the leading cause of death worldwide. Therefore, there is an urgent need for new therapeutic strategies focussing on atherosclerosis, the major underlying pathology of cardiovascular diseases characterized by an accumulation of lipids in an inflamed arterial/vessel wall. CD1d-restricted lipid-sensing natural killer T (NKT) cells, bridging the innate and adaptive immunity, and CD1d-expressing antigen-presenting cells are detected in atherosclerotic lesions of mice and humans. In this review we will summarize studies that point to a critical role for NKT cells in the pathogenesis of atherosclerosis and other cardiovascular diseases by the secretion of pro-atherogenic cytokines and cytotoxins. These pro-atherogenic NKT cells are potential targets for new therapeutic strategies in the prevention and treatment of cardiovascular diseases. Additionally, proteins transferring lipids during atherosclerosis, which are also important in the loading of lipids onto CD1d and possible endogenous ligands responsible for the activation of NKT cells during atherosclerosis will be discussed.

    New, S.E.P.; Aikawa, E.

    2011-01-01

    Cardiovascular calcification is an independent risk factor for cardiovascular morbidity and mortality. This disease of dysregulated metabolism is no longer viewed as a passive degenerative disease, but instead as an active process triggered by pro-inflammatory cues. Furthermore, a positive feedback loop of calcification and inflammation is hypothesized to drive disease progression in arterial calcification. Both calcific aortic valve disease and atherosclerotic arterial calcification may possess similar underlying mechanisms. Early histopathological studies first highlighted the contribution of inflammation to cardiovascular calcification by demonstrating the accumulation of macrophages and T lymphocytes in 'early' lesions within the aortic valves and arteries. A series of in vitro work followed, which gave a mechanistic insight into the stimulation of smooth muscle cells to undergo osteogenic differentiation and mineralization. The emergence of novel technology, in the form of animal models and more recently molecular imaging, has enabled accelerated progression of this field, by providing strong evidence regarding the concept of this disorder as an inflammatory disease. Although there are still gaps in our knowledge of the mechanisms behind this disorder, this review discusses the various studies that have helped form the concept of the inflammation-dependent cardiovascular calcification paradigm.

    Cardiovascular disease is the number one cause of death worldwide. It is broadly defined to include anything which adversely affects the heart or blood vessels. One-third of Americans have one or more forms of it. By one estimate, average human life expectancy would increase by seven years if it were eliminated. The mainstream medical model seeks mostly to "manage" cardiovascular disease with pharmaceuticals or to surgically bypass or reopen blocked vessels via angioplasty. These methods have proven highly useful and saved countless lives. Yet drug therapy may be costly and ongoing, and it carries the risk of side effects while often doing little or nothing to improve underlying health concerns. Similarly, angioplasty or surgery are invasive methods which entail risk. Laser therapy1 regenerates tissue, stimulates biological function, reduces inflammation and alleviates pain. Its efficacy and safety have been increasingly well documented in cardiovascular disease of many kinds. In this article we will explore the effects of laser therapy in angina, atherosclerosis, coronary artery disease, hypertension, hyperlipidemia, myocardial infarction, stroke and other conditions. The clinical application of various methods of laser therapy, including laserpuncture and transcutaneous, supravascular and intravenous irradiation of blood will be discussed. Implementing laser therapy in the treatment of cardiovascular disease offers the possibility of increasing the health and wellbeing of patients while reducing the costs and enhancing safety of medical care.

    Full Text Available As men grow older, testosterone (T levels decline and the significance of this change is debated. The evidence supporting a causal role for lower circulating T, or its metabolites dihydrotestosterone (DHT and estradiol, in the genesis of atherosclerosis and cardiovascular disease (CVD in men is limited. Observational studies associate low baseline T levels with carotid atherosclerosis, aortic and peripheral vascular disease, and with the incidence of cardiovascular events and mortality. Studies using mass spectrometry suggest that when total T is assayed optimally, calculation of free T might not necessarily improve risk stratification. There is limited evidence to support an association of estradiol with CVD. Interventional studies of T therapy in men with coronary artery disease have shown beneficial effects on exercise-induced myocardial ischemia. However, placebo-controlled, randomized clinical trials (RCTs of T therapy in men with the prespecified outcomes of cardiovascular events or deaths are lacking. Meta-analyses of randomized controlled trials of T published up to 2010 found no increase in cardiovascular events, mortality, or prostate cancer with therapy. Recently, in a trial of older men with mobility limitations, men randomized to receive a substantial dose of T reported cardiovascular adverse effects. This phenomenon was not reported from a comparable trial where men received a more conservative dose of T, suggesting a prudent approach should be adopted when considering therapy in frail older men with existing CVD. Adequately powered RCTs of T in middle-aged and older men are needed to clarify whether or not hormonal intervention would reduce the incidence of CVD.

  2. [Thyroid hormones and cardiovascular system].

    Science.gov (United States)

    Límanová, Zdeňka; Jiskra, Jan

    Cardiovascular system is essentially affected by thyroid hormones by way of their genomic and non-genomic effects. Untreated overt thyroid dysfunction is associated with higher cardiovascular risk. Although it has been studied more than 3 decades, in subclinical thyroid dysfunction the negative effect on cardiovascular system is much more controversial. Large meta-analyses within last 10 years have shown that subclinical hyperthyroidism is associated with higher cardiovascular risk than subclinical hypothyroidism. Conversely, in patients of age > 85 years subclinical hypothyroidism was linked with lower mortality. Therefore, subclinical hyperthyroidism should be rather treated in the elderly while subclinical hypothyroidism in the younger patients and the older may be just followed. An important problem on the border of endocrinology and cardiology is amiodarone thyroid dysfunction. Effective and safe treatment is preconditioned by distinguishing of type 1 and type 2 amiodarone induced hyperthyroidism. The type 1 should be treated with methimazol, therapeutic response is prolonged, according to recent knowledge immediate discontinuation of amiodarone is not routinely recommended and patient should be usually prepared to total thyroidectomy, or rather rarely 131I radioiodine ablation may be used if there is appropriate accumulation. In the type 2 there is a promt therapeutic response on glucocorticoids (within 1-2 weeks) with permanent remission or development of hypothyroidism. If it is not used for life-threatening arrhytmias, amiodarone may be discontinuated earlier (after several weeks). Amiodarone induced hypothyroidism is treated with levothyroxine without amiodarone interruption.Key words: amiodarone induced thyroid dysfunction - atrial fibrillation - cardiovascular risk - heart failure - hyperthyroidism - hypothyroidism - thyroid stimulating hormone.

    2014-01-01

    Sleep apnea is evident in approximately 10% of adults in the general population, but in certain cardiovascular diseases, and in particular those characterized by sodium and water retention, its prevalence can exceed 50%. Although sleep apnea is not as yet integrated into formal cardiovascular risk assessment algorithms, there is increasing awareness of its importance in the causation or promotion of hypertension, coronary artery disease, heart failure, atrial arrhythmias, and stroke, and thus, not surprisingly, as a predictor of premature cardiovascular death. Sleep apnea manifests as two principal phenotypes, both characterized by respiratory instability: obstructive (OSA), which arises when sleep-related withdrawal of respiratory drive to the upper airway dilator muscles is superimposed upon a narrow and highly compliant airway predisposed to collapse, and central (CSA), which occurs when the partial pressure of arterial carbon dioxide falls below the apnea threshold, resulting in withdrawal of central drive to respiratory muscles. The present objectives are to: (1) review the epidemiology and patho-physiology of OSA and CSA, with particular emphasis on the role of renal sodium retention in initiating and promoting these processes, and on population studies that reveal the long-term consequences of untreated OSA and CSA; (2) illustrate mechanical, autonomic, chemical, and inflammatory mechanisms by which OSA and CSA can increase cardiovascular risk and event rates by initiating or promoting hypertension, atherosclerosis, coronary artery disease, heart failure, arrhythmias, and stroke; (3) highlight insights from randomized trials in which treating sleep apnea was the specific target of therapy; (4) emphasize the present lack of evidence that treating sleep apnea reduces cardiovascular risk and the current clinical equipoise concerning treatment of asymptomatic patients with sleep apnea; and (5) consider clinical implications and future directions of clinical

    Full Text Available Aunque los términos ‘naturaleza de la ciencia’ y ‘modelo científico’ sean polisémicos en la Enseñanza de Ciencias, hay una especie de consenso en el área en cuanto a la importancia de la epistemología y del modelado científico en la formación de estudiantes y profesores. Por eso, diversos investigadores han dedicado esfuerzos a la enseñanza y a la investigación de esos temas. Parte de esos investigadores, así como nosotros, creen que la estrategia del modelado científico aplicada a la Enseñanza de Ciencias, además de ser una herramienta útil para la resolución de problemas, puede favorecer la construcción de una visión de ciencia adecuada a la práctica científica contemporánea. Pero una de las preguntas de investigación que sigue pendiente se refiere a los instrumentos de evaluación de las concepciones de estudiantes y profesores sobre esos temas. Dentro de ese contexto, este estudio tuvo el objetivo de validar un cuestionario para investigar en qué medida las concepciones de profesores sobre ciencia se correlacionan con las de modelado científico en el contexto de la Física. Compuesto inicialmente por 48 afirmaciones, el cuestionario fue aplicado a 218 personas. El análisis de las respuestas llevó a: a la identificación de cuatro factores subyacentes al contenido de las afirmaciones; b una fuerte correlación entre las concepciones sobre ciencia en general y modelado científico en Física; y c la construcción de dos formas alternativas y equivalentes del cuestionario, cada una con 23 afirmaciones, que pueden ser útiles cuando se pretende reducir posibles efectos de test en delineamientos experimentales. Enfatizamos que un instrumento de ese tipo puede ser útil como herramienta auxiliar para la evaluación de estrategias didácticas fundamentadas en elementos teórico - metodológicos pertinentes al proceso de modelado científico que pretendan integrar contenidos de naturaleza epistemológica en la

    Full Text Available Fundamentos: Desde su creación, el STAI se ha citado en más de 14.000 documentos, contando con más de 60 adaptaciones en diversos países. En algunas de ellas este cuestionario no cuenta con puntuaciones clínicas. El objetivo de este trabajo es determinar si el cuestionario State-Trait Anxiety Inventory (STAI tiene puntuaciones superiores en personas diagnosticadas de ansiedad respecto a la población general. Además, se pretende analizar si la consistencia interna es adecuada en personas con ansiedad. Método: Se realizó una búsqueda bibliográfica en Tripdatabase, Cochrane, Web of Knowledge, Scopus, PyscINFO y Scholar Google de documentos publicados entre 2008 y 2012. Se seleccionaron 131 artículos para la comparación entre pacientes diagnosticados de ansiedad respecto a la población general y 25 para la generalización de la fiabilidad. En los análisis se utilizó la d de Cohen para la comparación de medias (método de efectos aleatorios y para la generalización de la fiabilidad el alfa de Cronbach (método de efectos fijos. Resultados: En la comparación entre grupos, en la ansiedad estado (d = 1,39; IC95%: 1,22-1,56 y en la ansiedad rasgo (d = 1,74; IC95%: 1,56-1,91 las diferencias fueron estadísticamente significativas. Además de ello, la fiabilidad para pacientes con algún trastorno de ansiedad abarcó de 0,87 a 0,93. Conclusiones: El STAI es un cuestionario sensible para medir el nivel de ansiedad y fiable en personas diagnosticadas de crisis de angustia, fobia específica, fobia social, fobia social generalizada, trastorno de ansiedad generalizada, trastorno de estrés post-traumático, trastorno obsesivo compulsivo o trastorno por estrés agudo.

    Full Text Available This work shows the use of Structural Equations Modeling (SEM methodology to validate the conceptual structure of context questionnaires employed in national and international studies that evaluate the educational achievement of students. Unfortunately, evaluation agencies do not assign the same amount of technical resources to context questionnaires as those allotted to achievement tests, consequently the former are rarely subject to validity studies. In order to show the use of SEM methodology, a questionnaire was selected, which was employed by the National Institute for the Evaluation of Education to investigate the background factors associated with educational achievement of elementary school students in the third grade. It was administered to a national representative sample of 55,312 students. This questionnaire is analyzed according to SEM procedures of confirmatory factor analysis (CFA. The obtained results provide evidence for the constructive validity of this tool.

    Long-term exposure to air pollution increases cardiopulmonary morbidity and mortality, but it is not clear which components of air pollution are the most harmful, nor which time window of exposure is most relevant. Further studies at low exposure levels have also been called for. We analyzed two Swedish cohorts to investigate the effects of total and source-specific particulate matter (PM) on incident cardiovascular disease for different time windows of exposure. Two cohorts initially recruited to study predictors of cardiovascular disease (the PPS cohort and the GOT-MONICA cohort) were followed from 1990 to 2011. We collected data on residential addresses and assigned each individual yearly total and source-specific PM and Nitrogen Oxides (NO x ) exposures based on dispersion models. Using multivariable Cox regression models with time-dependent exposure, we studied the association between three different time windows (lag 0, lag 1-5, and exposure at study start) of residential PM and NO x exposure, and incidence of ischemic heart disease, stroke, heart failure and atrial fibrillation. During the study period, there were 2266 new-onset cases of ischemic heart disease, 1391 of stroke, 925 of heart failure and 1712 of atrial fibrillation. The majority of cases were in the PPS cohort, where participants were older. Exposure levels during the study period were moderate (median: 13µg/m 3 for PM 10 and 9µg/m 3 for PM 2.5 ), and similar in both cohorts. Road traffic and residential heating were the largest local sources of PM air pollution, and long distance transportation the largest PM source in total. In the PPS cohort, there were positive associations between PM in the last five years and both ischemic heart disease (HR: 1.24 [95% CI: 0.98-1.59] per 10µg/m 3 of PM 10 , and HR: 1.38 [95% CI: 1.08-1.77] per 5µg/m 3 of PM 2.5 ) and heart failure. In the GOT-MONICA cohort, there were positive but generally non-significant associations between PM and stroke (HR: 1

Método: La revisión incluyó artículos originales que utilizaban algún cuestionario para valorar la actividad física en los adultos mayores y ancianos. Se consultaron las bases de datos CINAHL y MEDLINE de 1993 a 2007. Los estudios seleccionados debían aportar información sobre uso, desarrollo o propiedades psicométricas de la medida. Se seleccionaron instrumentos utilizados en población mayor de 45 años. Se excluyeron los que evaluaban actividad física mediante estimación directa, métodos complejos o medidas de desempeño físico. Resultados: La búsqueda produjo 166 referencias y se identificaron 36 instrumentos. La mayoría cuantificaba la actividad física, y minoritariamente la autoeficacia y el estado de cambio de conducta. Los instrumentos son autoadministrados en la mitad de los casos. La fiabilidad más evaluada fue test-retest. En 14 instrumentos se estudió la validez de criterio, 11 con al menos dos métodos alternativos de medición. La validez de constructo fue evaluada en 26 instrumentos.

Debido en gran medida a que los tratamientos farmacológicos no son a día de hoy curativos de esta demencia, nos planteamos terapias alternativas que mejoren todos los parámetros de la enfermedad. En este sentido, se conoce la relación directa entre el estrés crónico que sufre el individuo en los últimos años de su vida, y la aparición de los primeros síntomas de la enfermedad destacando la depresión, ansiedad y tristeza. Y al pensar en los extraordinarios beneficios que tiene la música, nos planteamos valorar el impacto que tendría la musicoterapia en estos síntomas. Para ello, realizamos una intervención corta aplicando un protocolo estandarizado por nosotros. Paralelamente, realizamos cuestionarios estandarizados que miden la depresión y la ansiedad relacionadas con el estrés, y la felicidad relacionada con el bienestar, antes y después de la intervención, pudiendo valorar si hay mejoría, y si el empleo de los cuestionarios es adecuado para cuantificarla. Los resultados obtenidos muestran una gran mejora en los pacientes en relación a estos síntomas, pudiendo considerar por tanto a la musicoterapia como una herramienta terapéutica muy eficaz para disminuir el estrés de estos pacientes.

    Full Text Available Cardiovascular disease (CVD is the leading cause of death worldwide. This article focuses on current guidelines for the primary prevention of CVD and addresses management of key risk factors. Dietary modification, weight loss, exercise, and tobacco use cessation are specific areas where focused efforts can successfully reduce CVD risk on both an individual and a societal level. Specific areas requiring management include dyslipidemia, hypertension, physical activity, diabetes, aspirin use, and alcohol intake. These preventive efforts have major public health implications. As the global population continues to grow, health care expenditures will also rise, with the potential to eventually overwhelm the health care system. Therefore it is imperative to apply our collective efforts on CVD prevention to improve the cardiovascular health of individuals, communities, and nations.

    Do molecularly-targeted contrast agents have what it takes to usher in a paradigm shift as to how we will image cardiovascular disease in the near future? Moreover, are non-invasive vulnerable plaque detection and preemptive treatments with these novel nanoparticulate agents within reach for clinical applications? In this article, we attempt to make a compelling case for how the advent of molecularly-targeted nanoparticle technology may change the way we detect atherosclerotic lesions, determine their clinical significance and even provide non-invasive treatments. Focusing on imaging with cardiovascular MR, an overview of the latest developments in this rapidly evolving field of so-called "intelligent" contrast agents that are able to interrogate the vascular wall and various complementary advanced imaging technologies are presented.

    Full Text Available Midlife cardiovascular risk factors, including diabetes, hypertension, dyslipemia, and an unhealthy lifestyle, have been linked to subsequent incidence, delay of onset, and progression rate of Alzheimer disease and vascular dementia. Conversely, optimal treatment of cardiovascular risk factors prevents and slows down age-related cognitive disorders. The impact of antihypertensive therapy on cognitive outcome in patients with hypertension was assessed in large trials which demonstrated a reduction in progression of MRI white matter hyperintensities, in cognitive decline and in incidence of dementia. Large-scale database correlated statin use and reduction in the incidence of dementia, mainly in patients with documented atherosclerosis, but clinical trials failed to reach similar conclusions. Whether a multitargeted intervention would substantially improve protection, quality of life, and reduce medical cost expenditures in patients with lower risk profile has not been ascertained. This would require appropriately designed trials targeting large populations and focusing on cognitive decline as a primary outcome endpoint.

    Erectile dysfunction is common in the patient with cardiovascular disease. It is an important component of the quality of life and it also confers an independent risk for future cardiovascular events. The usual 3-year time period between the onset of erectile dysfunction symptoms and a cardiovascular event offers an opportunity for risk mitigation. Thus, sexual function should be incorporated into cardiovascular disease risk assessment for all men. A comprehensive approach to cardiovascular risk reduction (comprising of both lifestyle changes and pharmacological treatment) improves overall vascular health, including sexual function. Proper sexual counselling improves the quality of life and increases adherence to medication. This review explores the critical connection between erectile dysfunction and cardiovascular disease and evaluates how this relationship may influence clinical practice. Algorithms for the management of patient with erectile dysfunction according to the risk for sexual activity and future cardiovascular events are proposed.

  7. Cardiovascular effects of air pollution.

    Brook, Robert D

    2008-09-01

    Air pollution is a heterogeneous mixture of gases, liquids and PM (particulate matter). In the modern urban world, PM is principally derived from fossil fuel combustion with individual constituents varying in size from a few nanometres to 10 microm in diameter. In addition to the ambient concentration, the pollution source and chemical composition may play roles in determining the biological toxicity and subsequent health effects. Nevertheless, studies from across the world have consistently shown that both short- and long-term exposures to PM are associated with a host of cardiovascular diseases, including myocardial ischaemia and infarctions, heart failure, arrhythmias, strokes and increased cardiovascular mortality. Evidence from cellular/toxicological experiments, controlled animal and human exposures and human panel studies have demonstrated several mechanisms by which particle exposure may both trigger acute events as well as prompt the chronic development of cardiovascular diseases. PM inhaled into the pulmonary tree may instigate remote cardiovascular health effects via three general pathways: instigation of systemic inflammation and/or oxidative stress, alterations in autonomic balance, and potentially by direct actions upon the vasculature of particle constituents capable of reaching the systemic circulation. In turn, these responses have been shown to trigger acute arterial vasoconstriction, endothelial dysfunction, arrhythmias and pro-coagulant/thrombotic actions. Finally, long-term exposure has been shown to enhance the chronic genesis of atherosclerosis. Although the risk to one individual at any single time point is small, given the prodigious number of people continuously exposed, PM air pollution imparts a tremendous burden to the global public health, ranking it as the 13th leading cause of morality (approx. 800,000 annual deaths).

    Cardiovascular (CV) response consists of changes in CV parameters such as heart rate blood pressure and heart contraction force in reaction to an event or set of events. It is significant for multiple reasons perhaps most notably because research suggests that it affects the development and progression of heart disease. Disease models vary but most assume that characteristically strong and prolonged CV responses confer health risk. Psychologists have long suspected linkages between motivation...

    Full Text Available Zhejiang province, China, has implemented a population based, real-time surveillance system that tracks acute cardiovascular diseases (CVDs events since 2001. This study aimed to describe the system and report CVD incidence, mortality and case-fatality between urban and rural areas in Zhejiang in 2012. The surveillance system employs a stratified random sampling method covering all permanent residents of 30 counties/districts in Zhejiang. Acute CVD events such as coronary heart disease (CHD and stroke were defined, registered and reviewed based on the adapted MONICA (Monitoring Trends and Determinants in Cardiovascular Disease definitions. Data were collected from health facilities, vital registries, supplementary surveys, and additional investigations, and were checked for data quality before input in the system. We calculated the rates and compared them by gender, age and region. In 2012, the incidence, mortality and case-fatality of total acute CVD events were 367.0 (CHD 59.1, stroke 307.9, 127.1 (CHD 43.3, stroke 83.8 per 100,000 and 34.6% (CHD 73.2%, stroke 27.2%, respectively. Compared with rural areas, urban areas reported higher incidence and mortality but lower case-fatality rates for CHD (P<0.001, while lower incidence but higher mortality and case-fatality rates for stroke (P<0.001. We found significant differences on CHD and stroke epidemics between urban and rural areas in Zhejiang. Special attentions need to be given to stroke control, especially in rural areas.

    Low birth weight serves as a crude proxy for impaired growth during fetal life and indicates a failure for the fetus to achieve its full growth potential. Low birth weight can occur in response to numerous etiologies that include complications during pregnancy, poor prenatal care, parental smoking, maternal alcohol consumption or stress. Numerous epidemiological and experimental studies demonstrate that birth weight is inversely associated with blood pressure and coronary heart disease. Sex and age impact the developmental programming of hypertension. In addition, impaired growth during fetal life also programs enhanced vulnerability to a secondary insult. Macrosomia, which occurs in response to maternal obesity, diabetes and excessive weight gain during gestation, is also associated with increased cardiovascular risk. Yet, the exact mechanisms that permanently change the structure, physiology and endocrine health of an individual across their lifespan following altered growth during fetal life are not entirely clear. Transmission of increased risk from one generation to the next in the absence of an additional prenatal insult indicates an important role for epigenetic processes. Experimental studies also indicate that the sympathetic nervous system, the renin angiotensin system, increased production of oxidative stress and increased endothelin play an important role in the developmental programming of blood pressure in later life. Thus, this review will highlight how adverse influences during fetal life and early development program an increased risk for cardiovascular disease including high blood pressure and provide an overview of the underlying mechanisms that contribute to the fetal origins of cardiovascular pathology.

    2006-01-01

    Full Text Available Apolipoprotein E is a polymorphic glycoprotein who interacts with the lipoprotein receptors (LRP-Receptor Related Protein and the receptors for low density lipoproteins of (LDL receptors. When lipoproteins bring up the receptors begins lipids captation and degradation which allows cholesterol utilization, taking place an intracellular auto regulation. The three isoforms of greater importance: Apo E2, E3 and E4 are product of three alleles e2, e3, e4 of one only gene. This factor is related with the amount of lipoproteins that contains ApoE for E/B receptors. A low concentration of lipoproteins with ApoE can increase the activity of LDL receptors and consequently downward the circulating LDL. In the other hand particles with Apo E3 or Apo E4, can cause a downward regulation of LDL and in this way produces a LDL plasma elevation. Many studies in human populations have concluded that this polymorphism of apoE and the plasma variation of lipoproteins are associated with cardiovascular risk. Cardiovascular disease is the result of different interaction between factors which are genetic factor specially ApoE polymorphism e4 allelic of ApoE can explain, in some degree, the greater frequency of cardiovascular disease in those who carries it.

    A significant body of evidence demonstrates that diets rich in fruits and vegetables promote health and attenuate, or delay, the onset of various diseases, including cardiovascular disease, diabetes, certain cancers, and several other age-related degenerative disorders. The concept that moderate chocolate consumption could be part of a healthy diet has gained acceptance in past years based on the health benefits ascribed to selected cocoa components. Specifically, cocoa as a plant and chocolate as food contain a series of chemicals that can interact with cell and tissue components, providing protection against the development and amelioration of pathological conditions. The most relevant effects of cocoa and chocolate have been related to cardiovascular disease. The mechanisms behind these effects are still under investigation. However, the maintenance or restoration of vascular NO production and bioavailability and the antioxidant effects are the mechanisms most consistently supported by experimental data. This review will summarize the most recent research on the cardiovascular effects of cocoa flavanols and related compounds.

  19. Cardiovascular Effects of Calcium Supplements

    Directory of Open Access Journals (Sweden)

    Ian R. Reid

    2013-07-01

    Full Text Available Calcium supplements reduce bone turnover and slow the rate of bone loss. However, few studies have demonstrated reduced fracture incidence with calcium supplements, and meta-analyses show only a 10% decrease in fractures, which is of borderline statistical and clinical significance. Trials in normal older women and in patients with renal impairment suggest that calcium supplements increase the risk of cardiovascular disease. To further assess their safety, we recently conducted a meta-analysis of trials of calcium supplements, and found a 27%–31% increase in risk of myocardial infarction, and a 12%–20% increase in risk of stroke. These findings are robust because they are based on pre-specified analyses of randomized, placebo-controlled trials and are consistent across the trials. Co-administration of vitamin D with calcium does not lessen these adverse effects. The increased cardiovascular risk with calcium supplements is consistent with epidemiological data relating higher circulating calcium concentrations to cardiovascular disease in normal populations. There are several possible pathophysiological mechanisms for these effects, including effects on vascular calcification, vascular cells, blood coagulation and calcium-sensing receptors. Thus, the non-skeletal risks of calcium supplements appear to outweigh any skeletal benefits, and are they appear to be unnecessary for the efficacy of other osteoporosis treatments.

  8. Oxidative stress in cardiovascular diseases

    Full Text Available Oxidative stress caused by various oxygen containing free radicals and reactive species (collectively called "Reactive Oxygen Species" or ROS has long been attributed to cardiovascular diseases. In human body, major oxidizing species are super oxide, hydrogen peroxide, hydroxyl radical, peroxy nitrite etc. ROS are produced from distinct cellular sources, enzymatic and non-enzymatic; have specific physicochemical properties and often have specific cellular targets. Although early studies in nineteen sixties and seventies highlighted the deleterious effects of these species, later it was established that they also act as physiological modulators of cellular functions and diseases occur only when ROS production is deregulated. One of the major sources of cellular ROS is Nicotinamide adenine dinucleotide phosphate oxidases (Noxes that are expressed in almost all cell types. Superoxide and hydrogen peroxide generated from them under various conditions act as signal transducers. Due to their immense importance in cellular physiology, various Nox inhibitors are now being developed as therapeutics. Another free radical of importance in cardiovascular system is nitric oxide (a reactive nitrogen species generated from nitric oxide synthase(s. It plays a critical role in cardiac function and its dysregulated generation along with superoxide leads to the formation of peroxynitrite a highly deleterious agent. Despite overwhelming evidences of association between increased level of ROS and cardiovascular diseases, antioxidant therapies using vitamins and omega 3 fatty acids have largely been unsuccessful till date. Also, there are major discrepancies between studies with laboratory animals and human trials. It thus appears that the biology of ROS is far complex than anticipated before. A comprehensive understanding of the redox biology of diseases is thus needed for developing targeted therapeutics.

    Full Text Available   Recently, cell therapy has sparked a revolution in ischemic heart disease that will in the future help clinicians to cure patients. Earlier investigations in animal models and clinical trials have suggested that positive paracrine effects such as neoangiogenesis and anti-apoptotic can improve myocardial function. In this regard the Royan cell therapy center designed a few trials in collaboration with multi hospitals such as Baqiyatallah, Shahid Lavasani, Tehran Heart Center, Shahid rajaee, Masih daneshvari, Imam Reza, Razavi and Sasan from 2006. Their results were interesting. However, cardiac stem cell therapy still faces great challenges in optimizing the treatment of patients. Keyword: Cardiovascular disease, Cell therapy.

    Management of SAS and cardiovascular disease risk should be closely linked. It is important to screen for cardiovascular disease risk in patients with SAS and vice versa. CSA/CSR may be improved by ventilation strategies in heart failure, but benefit remains to be proven. For OSA, although CPAP may reduce cardiovascular disease risk, its main benefit is symptom control. In the longer-term, CPAP should be used alongside standard cardiovascular risk reduction strategies including robust weight management programmes, with referral for bariatric surgery in appropriate cases. CPAP and NIV should be considered for acute admissions with decompensated cardiac failure.

    Improvements in treatment and earlier diagnosis have both contributed to increased survival for many cancer patients. Unfortunately, many treatments carry a risk of late effects including cardiovascular diseases (CVDs), possibly leading to significant morbidity and mortality. In this paper we describe current knowledge of the cardiotoxicity arising from cancer treatments, outline gaps in knowledge, and indicate directions for future research and guideline development, as discussed during the 2014 Cancer Survivorship Summit organised by the European Organisation for Research and Treatment of Cancer (EORTC). Better knowledge is needed of the late effects of modern systemic treatments and of radiotherapy to critical structures of the heart, including the effect of both radiation dose and volume of the heart exposed. Research elucidating the extent to which treatments interact in causing CVD, and the mechanisms involved, as well as the extent to which treatments may increase CVD indirectly by increasing cardiovascular risk factors is also important. Systematic collection of data relating treatment details to late effects is needed, and great care is needed to obtain valid and generalisable results. Better knowledge of these cardiac effects will contribute to both primary and secondary prevention of late complications where exposure to cardiotoxic treatment is unavoidable. Also surrogate markers would help to identify patients at increased risk of cardiotoxicity. Evidence-based screening guidelines for CVD following cancer are also needed. Finally, risk prediction models should be developed to guide primary treatment choice and appropriate follow up after cancer treatment. PMID:26217163

    Full Text Available Dietary saturated fat (SF intake has been shown to increase low density lipoprotein (LDL cholesterol and therefore has been associated with increased risk of cardiovascular disease (CVD. This evidence coupled with inferences from epidemiologic studies and clinical trials, had led to longstanding public health recommendations for limiting SF intake as a means of preventing CVD. However the relationship between SF and CVD risk remains controversial, due at least in part to the intrinsic limitations of clinical studies that have evaluated this relationship. A recent meta analysis showed that current evidence does not clearly support cardiovascular guidelines that encourage high consumption of polyunsaturated fatty acids (PUFA and low consumption of total SF. They found weak positive associations between circulating palmitic and stearic acids (found largely in palm oil and animal fats, respectively and CVD, whereas circulating margaric acid (a dairy fat significantly reduced the risk of CVD.(2,3 Saturated fat are not associated with all cause mortality, CVD, CHD, ischemic stroke or type 2 diabetes, but the evidence is heterogenous with methodological limitations.

  1. Marijuana Use and Cardiovascular Disease.

    Marijuana is currently the most used illicit substance in the world. With the current trend of decriminalization and legalization of marijuana in the US, physicians in the US will encounter more patients using marijuana recreationally over a diverse range of ages and health states. Therefore, it is relevant to review marijuana's effects on human cardiovascular physiology and disease. Compared with placebo, marijuana cigarettes cause increases in heart rate, supine systolic and diastolic blood pressures, and forearm blood flow via increased sympathetic nervous system activity. These actions increase myocardial oxygen demand to a degree that they can decrease the time to exercise-induced angina in patients with a history of stable angina. In addition, marijuana has been associated with triggering myocardial infarctions (MIs) in young male patients. Smoking marijuana has been shown to increase the risk of MI onset by a factor of 4.8 for the 60 minutes after marijuana consumption, and to increase the annual risk of MI in the daily cannabis user from 1.5% to 3% per year. Human and animal models suggest that this effect may be due to coronary arterial vasospasm. However, longitudinal studies have indicated that marijuana use may not have a significant effect on long-term mortality. While further research is required to definitively determine the impact of marijuana on cardiovascular disease, it is reasonable to recommend against recreational marijuana use, especially in individuals with a history of coronary artery disorders.

    Full Text Available As in other Western countries, cardiovascular disease (CVD is the leading cause of death among women in Taiwan, exceeding the mortality from cervical or breast cancer. Women generally present with CVD after menopause and later than men, since menopause-related estrogen deficiency has been considered to be associated with an increased risk for CVD. Thus, coronary artery diseases and stroke are the two main contributors of mortality among postmenopausal women. Observational studies have reported a reduction in coronary artery disease risk after hormone therapy (HT ranging from 31-44%. However, recent randomized controlled trials that evaluated the effect of HT on primary and secondary CVD prevention have questioned the efficacy of HT, despite confirming the lipid-lowering effect of estrogen. However, a cluster of factors are responsible for the genesis and progression of CVD. Until we further evaluate their specific actions and how these different factors interact, the issue related to HT and cardiovascular risk will remain unsettled. Since these studies have contributed to our understanding of the benefits and risks associated with HT, HT use should be individualized after consideration of the condition of each postmenopausal patient. Ideally, the efficacy of different preparations and dosages of HT in postmenopausal women who are at risk of CVD, before atheromatous lesions have developed, should be investigated.

    The quality management of an organization can be defined as the ability to identify, plan and implement programs of measure, analysis, verification and control that allow to monitor management, resources, activities, processes and output/outcome of the same organization, including the satisfaction of the customers. Whatever the model used, it is demonstrated that the management-quality system, either for professional quality or for organization, turns out to be effective even in the health organizations within and to any level of organizational-structural complexity. The present paper concerns the experience of the Italian Society of Cardiovascular Echography (SIEC) on quality certification, both as a scientific society compared to other health organizations and to cardiovascular echo laboratories, and the definition of minimum requirements for the accreditation of the same laboratories. The model most frequently used for quality management is represented by the ISO 9000: Vision 2000, that is a management model with specific reference to the organization and the customer satisfaction. The model applied to the health structure needs a rapid change in mentality that addresses the operators to define, share and achieve objectives to be brought on by means of an active collaboration, group activity and deep sense of belonging necessary to the attainment of expected objectives. When the model is applied by a scientific society, it is necessary to take into account the different structural and functional organization, the constitution and the operators differing on the point of view of origin, experiences, mentality, and roles. The ISO 9000: Vision 2000 model can be applied also to the cardiovascular echo laboratory which may be compared to a simple organization; for its corrected functioning, SIEC has defined minimal requirements for the accreditation, realization and modalities to carry out and manage quality. The quality system represents a new way of operating of an

    Full Text Available In the past twenty years the heaviest burden of cardiovascular diseases has begun to shift from developed to developing countries. However, little is known about the real needs for cardiovascular care in these countries and how well those needs are being met. This study aims to investigate the prevalence and determinants of unmet needs for cardiovascular care based on objective assessment.Multilevel analysis is used to analyse the determinants of met needs and multilevel multiple imputation is applied to manage missing data. The 2008 Indonesian Family Life Survey (IFLS4 survey is the source of the household data used in this study, while district data is sourced from the Ministry of Health and Ministry of Finance. The data shows that nearly 70% of respondents with moderate to high cardiovascular risk failed to receive cardiovascular care. Higher income, possession of health insurance and residence in urban areas are significantly associated with met needs for cardiovascular care, while health facility density and physician density show no association with them.The prevalence of unmet needs for cardiovascular care is considerable in Indonesia. Inequality persists as a factor in meeting needs for cardiovascular care as the needs of people with higher incomes and those living in urban areas are more likely to be met. Alleviation of poverty, provision of health care insurance for the poor, and improvement in the quality of healthcare providers are recommended in order to meet this ever-increasing need.

    Full Text Available Chronic hepatitis C virus (HCV infection is a systemic disease that leads to increased risks of cirrhosis and its complications, as well as extrahepatic disturbances, including immune-related disorders and metabolic alterations such as insulin resistance and steatosis. Recent accumulating evidence suggests that HCV infection can increase cardiovascular risk, and that viral eradication can improve cardiovascular outcomes in the clinical setting. These data are strengthened by evidence identifying potential mechanisms (indirectly linking HCV infection to vascular damage. However, the high prevalence of both HCV infection and cardiovascular alterations, as well as the presence of contrasting results not identifying any association between HCV infection and cardiovascular dysfunction, provides uncertainty about a direct association of HCV infection with cardiovascular risk. Further studies are needed to clarify definitively the role of HCV infection in cardiovascular alterations, as well as the impact of viral eradication on cardiovascular outcomes. These features are now more attractive, considering the availability of new, safe, and very effective interferon-free antiviral agents for the treatment of HCV infection. This review aims to discuss carefully available data on the relationship between HCV infection and cardiovascular risk.

    Full Text Available Psychological stress has been proposed as a major contributor to the progression of cardiovascular disease (CVD. Acute mental stress can activate the sympathetic-adrenal-medullary (SAM axis, eliciting the release of catecholamines (NE and EPI resulting in the elevation of heart rate (HR and blood pressure (BP. Combined stress (psychological and physical can exacerbate these cardiovascular responses, which may partially contribute to the elevated risk of CVD and increased proportionate mortality risks experienced by some occupations (e.g., firefighting and law enforcement. Studies have supported the benefits of physical activity on physiological and psychological health, including the cardiovascular response to acute stress. Aerobically trained individuals exhibit lower sympathetic nervous system (e.g., HR reactivity and enhanced cardiovascular efficiency (e.g., lower vascular reactivity and decreased recovery time in response to physical and/or psychological stress. In addition, resistance training has been demonstrated to attenuate cardiovascular responses and improve mental health. This review will examine stress-induced cardiovascular reactivity and plausible explanations for how exercise training and physical fitness (aerobic and resistance exercise can attenuate cardiovascular responses to stress. This enhanced functionality may facilitate a reduction in the incidence of stroke and myocardial infarction. Finally, this review will also address the interaction of obesity and physical activity on cardiovascular reactivity and CVD.

MÉTODOS: El estudio de validación se llevó a cabo entre octubre de 2002 y octubre de 2003 en el Programa de Medicina Interna General del Hospital de Clínicas, Universidad de Buenos Aires, Argentina. El cuestionario original en español se había formulado en clínicas de salud sexual y reproductiva de cinco países de América Latina y el Caribe. En él se abarcaban las formas más frecuentes de violencia basada en el género (VBG (emocional, física, sexual y abuso sexual durante la niñez; se exploraba cómo, cuándo y quién perpetró la agresión, y se indagaba acerca de la percepción de la paciente con respecto al peligro en que se encontraba. Durante la investigación en Buenos Aires se evaluaron el formato y el contenido teórico de la encuesta y se realizaron validaciones lingüística y psicométrica. Se evaluó la confiabilidad del instrumento en términos de reproducibilidad, estabilidad y coherencia interna. RESULTADOS: Se comprobó que las mujeres encuestadas comprendieron bien las preguntas, los ejemplos dados y las opciones de respuesta y que no percibieron la encuesta como un elemento de intimidación, ni una intromisión en su vida privada. En general consideraron su aplicación en el ámbito de la atención primaria como una oportunidad clave para expresar su sufrimiento y recibir ayuda.

    Full Text Available Recent studies demonstrated that mitochondria play an important role in the cardiovascular system and mutations of mitochondrial DNA affect coronary artery disease, resulting in hypertension, atherosclerosis, and cardiomyopathy. Traditional Chinese medicine (TCM has been used for thousands of years to treat cardiovascular disease, but it is not yet clear how TCM affects mitochondrial function. By reviewing the interactions between the cardiovascular system, mitochondrial DNA, and TCM, we show that cardiovascular disease is negatively affected by mutations in mitochondrial DNA and that TCM can be used to treat cardiovascular disease by regulating the structure and function of mitochondria via increases in mitochondrial electron transport and oxidative phosphorylation, modulation of mitochondrial-mediated apoptosis, and decreases in mitochondrial ROS. However further research is still required to identify the mechanism by which TCM affects CVD and modifies mitochondrial DNA.

    2013-01-01

    The social determinants of health (SDH) are recognized as a prominent influence on health outcomes across the lifespan. Racism is identified as a key SDH. In this article, the authors describe the concept of racism as an SDH, its impact in discriminatory actions and inactions, and the implications for cardiovascular nurses. Although research in Canada on the links among racism, stress, and cardiovascular disease is limited, there is growing evidence about the stress of racism and its long-term impact on cardiovascular health. The authors discuss how cardiovascular nursing could be enhanced through an understanding of racism-related stress, and race-based differences in cardiovascular care. The authors conclude with strategies for action to address this nursing concern.

    To design a diagnostic protocol that uses appropriate techniques, including ultrasonography, to assess cardiovascular health and detect primary cardiac diseases in gorillas and to establish a database of reference values for cardiac measurements in clinically normal gorillas. Prospective study. 5 adult male lowland gorillas from 11 to 18 years old. A complete cardiac evaluation was performed on anesthetized gorillas, including physical examination, thoracic radiography, electrocardiography, echocardiography, blood pressure determination, CBC, serum biochemical analyses, and serologic assay for viral diseases. Standard cardiac measurements were made from images collected during ultrasonography. Cardiac measurements derived from ultrasonographic images were consistent with those considered normal in human beings. Results of other diagnostic tests were also considered normal. Cardiac disease is the primary cause of mortality in old captive gorillas. The technique used here provided excellent evaluation of cardiac function. Use of these techniques will allow early detection of cardiac disease, making treatment or medical management possible

    2015-12-01

    The use of cacao for health benefits dates back at least 3000 years. Our understanding of cacao has evolved with modern science. It is now felt based on extensive research the main health benefits of cacao stem from epicatechin, a flavanol found in cacao. The process of manufacturing dark chocolate retains epicatechin, whereas milk chocolate does not contain significant amounts of epicatechin. Thus, most of the current research studies are focused on dark chocolate. Both epidemiological and clinical studies suggest a beneficial effect of dark chocolate on blood pressure, lipids, and inflammation. Proposed mechanisms underlying these benefits include enhanced nitric oxide bioavailability and improved mitochondrial structure/function. Ultimately, further studies of this promising compound are needed to elucidate its potential for prevention and treatment of cardiovascular and metabolic diseases as well as other diseases that have underlying mechanisms of mitochondrial dysfunction and nitric oxide deficiency.

  20. Understanding changes in cardiovascular pathophysiology.

    Science.gov (United States)

    Chummun, Harry

    Cardiovascular pathophysiological changes, such as hypertension and enlarged ventricles, reflect the altered functions of the heart and its circulation during ill-health. This article examines the normal and altered anatomy of the cardiac valves, the contractile elements and enzymes of the myocardium, the significance of the different factors associated with cardiac output, and the role of the autonomic nervous system in the heart beat. It also explores how certain diseases alter these functions and result in cardiac symptoms. Nurses can benefit from knowledge of these specific changes, for example, by being able to ask relevant questions in order to ascertain the nature of a patients condition, by being able to take an effective patient history and by being able to read diagnostic results, such as electrocardiograms and cardiac enzyme results. All this will help nurses to promote sound cardiac care based on a physiological rationale.

    Riley, Callum James, and Matthew Gavin. Physiological changes to the cardiovascular system at high altitude and its effects on cardiovascular disease. High Alt Med Biol. 18:102-113, 2017.-The physiological changes to the cardiovascular system in response to the high altitude environment are well understood. More recently, we have begun to understand how these changes may affect and cause detriment to cardiovascular disease. In addition to this, the increasing availability of altitude simulation has dramatically improved our understanding of the physiology of high altitude. This has allowed further study on the effect of altitude in those with cardiovascular disease in a safe and controlled environment as well as in healthy individuals. Using a thorough PubMed search, this review aims to integrate recent advances in cardiovascular physiology at altitude with previous understanding, as well as its potential implications on cardiovascular disease. Altogether, it was found that the changes at altitude to cardiovascular physiology are profound enough to have a noteworthy effect on many forms of cardiovascular disease. While often asymptomatic, there is some risk in high altitude exposure for individuals with certain cardiovascular diseases. Although controlled research in patients with cardiovascular disease was largely lacking, meaning firm conclusions cannot be drawn, these risks should be a consideration to both the individual and their physician.

    2008-06-01

    Dementias, such as Alzheimer's disease (AD) and vascular dementia, are disorders of aging populations and represent a significant economic burden. Evidence is accumulating to suggest that cardiovascular disease (CVD) risk factors may be instrumental in the development of dementia. The goal of this review was to discuss the relationship between specific CVD risk factors and dementia and how current treatment strategies for dementia should focus on reducing CVD risks. We conducted a review of the literature for the simultaneous presence of 2 major topics, cardiovascular risk factors and dementia (eg, AD). Special emphasis was placed on clinical outcome studies examining the effects of treatments of pharmacologically modifiable CVD risk factors on dementia and cognitive impairment. Lifestyle risk factors for CVD, such as obesity, lack of exercise, smoking, and certain psychosocial factors, have been associated with an increased risk of cognitive decline and dementia. Some evidence suggests that effectively managing these factors may prevent cognitive decline/dementia. Randomized, placebo-controlled trials of antihypertensive medications have found that such therapy may reduce the risk of cognitive decline, and limited data suggest a benefit for patients with AD. Some small open-label and randomized clinical trials of statins have observed positive effects on cognitive function; larger studies of statins in patients with AD are ongoing. Although more research is needed, current evidence indicates an association between CVD risk factors--such as hypertension, dyslipidemia, and diabetes mellitus--and cognitive decline/dementia. From a clinical perspective, these data further support the rationale for physicians to provide effective management of CVD risk factors and for patients to be compliant with such recommendations to possibly prevent cognitive decline/dementia.

    Full Text Available In the last 15 years, highly active antiretroviral therapy (HAART has determined a dramatic reduction of both morbidity and mortality in human immunodeficiency virus (HIV-infected subjects, transforming this infection in a chronic and manageable disease. Patients surviving with HIV in the developed world, in larger number men,  are becoming aged. As it would be expected for a population of comparable age, many HIV-infected individuals report a family history of cardiovascular disease, a small proportion have already experienced a cardiovascular event and an increasing proportion has diabetes mellitus. Smoking rate is very high while an increasing proportion of HIV-infected individuals have dyslipidaemia. Studies suggest that these traditional risk factors could play an important  role in the development of cardiovascular disease in these patients as they do in the general population. Thus, whilst the predicted 10-year cardiovascular disease risk remains relatively low at present, it will likely increase in relation to the progressive aging of  this patient population. Thus, the long-term follow-up of HIV infected patients has to include co-morbidity management such as cardiovascular disease prevention and treatment. Two intriguing aspects related to the cardiovascular risk in patients with HIV infection are the matter of current investigation: 1 while these subjects share many cardiovascular risk factors with the general population, HIV infection itself increases cardiovascular risk; 2 some HAART regimens too influence atherosclerotic profile, partly due to lipid changes. Although the mechanisms involved in the development of cardiovascular complications in HIV-infected patients remain to be fully elucidated, treatment guidelines recommending interventions to prevent cardiovascular disease in these individuals are already available; however, their application is still limited.

    There is growing evidence for the importance of cardiovascular risk factors in dementia development, including Alzheimer's disease. As cardiovascular risk profiles vary greatly by gender, with men suffering a greater burden of cardiovascular risk in midlife, this could lead to differences in dementia risk. To explore current evidence on the association between components of the cardiovascular risk profile and dementia risk in women and men, we reviewed all studies reporting the risk of dementia associated with cardiovascular risk factors stratified by gender and found 53 eligible articles out of over 4,000 published since the year 2000. Consistent results were found: 1) for exposures acting specifically in women: Overweight/obesity (harmful) and physical activity (protective), and 2) for exposures acting similarly in women and men: Moderate alcohol (protective) and hypertension, diabetes, and depression (harmful). A modified effect of tobacco or high cholesterol/statin use remained controversial. Available data do not allow us to assess whether selection of men with healthier cardiovascular profile (due to cardiovascular death in midlife) could lead in late life either to a difference in the distribution of risk factors or to a differential effect of these risk factors by gender. We recommend that results on dementia risk factors, especially cardiovascular ones, be reported systematically by gender in all future studies. More generally, as cardiovascular risk profiles evolve over time, more attention needs to be paid to the detection and correction of cardiovascular risk factors, as early as possible in the life course, and as actively in women as in men.

    With increasing use of pediatric cardiovascular MRI, it is important for all imagers to become familiar with the spectrum of non-cardiovascular imaging findings that can be encountered. This study aims to ascertain the prevalence and nature of these findings in pediatric cardiovascular MRIs performed at our institution. We retrospectively evaluated reports of all cardiovascular MRI studies performed at our institute from January 2008 to October 2012 in patients younger than18 years. Most studies (98%) were jointly interpreted by a pediatric cardiologist and a radiologist. We reviewed the electronic medical records of all cases with non-cardiovascular findings, defined as any imaging finding outside the cardiovascular system. Non-cardiovascular findings were classified into significant and non-significant, based on whether they were known at the time of imaging or they required additional workup or a change in management. In 849 consecutive studies (mean age 9.7 ± 6.3 years), 145 non-cardiovascular findings were found in 140 studies (16.5% of total studies). Overall, 51.0% (74/145) of non-cardiovascular findings were in the abdomen, 30.3% (44/145) were in the chest, and 18.6% (27/145) were in the spine. A total of 19 significant non-cardiovascular findings were observed in 19 studies in individual patients (2.2% of total studies, 47% male, mean age 5.9 ± 6.7 years). Significant non-cardiovascular findings included hepatic adenoma, arterially enhancing focal liver lesions, asplenia, solitary kidney, pelvicaliectasis, renal cystic diseases, gastric distention, adrenal hemorrhage, lung hypoplasia, air space disease, bronchial narrowing, pneumomediastinum and retained surgical sponge. Non-cardiovascular findings were seen in 16.5% of cardiovascular MRI studies in children, of which 2.2% were clinically significant findings. Prevalence and nature of these non-cardiovascular findings are different from those reported in adults. Attention to these findings is important

    High blood pressure is an important risk factor for cardiovascular disease and cardiovascular events worldwide. Clinical and epidemiological studies suggest that cocoa-rich products reduce the risk of cardiovascular disease. According to this, cocoa has a high content in polyphenols, especially flavanols. Flavanols have been described to exert favorable effects on endothelium-derived vasodilation via the stimulation of nitric oxide-synthase, the increased availability of l-arginine, and the decreased degradation of NO. Cocoa may also have a beneficial effect by protecting against oxidative stress alterations and via decreased platelet aggregation, decreased lipid oxidation, and insulin resistance. These effects are associated with a decrease of blood pressure and a favorable trend toward a reduction in cardiovascular events and strokes. Previous meta-analyses have shown that cocoa-rich foods may reduce blood pressure. Long-term trials investigating the effect of cocoa products are needed to determine whether or not blood pressure is reduced on a chronic basis by daily ingestion of cocoa. Furthermore, long-term trials investigating the effect of cocoa on clinical outcomes are also needed to assess whether cocoa has an effect on cardiovascular events. A 3 mmHg systolic blood pressure reduction has been estimated to decrease the risk of cardiovascular and all-cause mortality. This paper summarizes new findings concerning cocoa effects on blood pressure and cardiovascular health, focusing on putative mechanisms of action and "nutraceutical " viewpoints.

    Radiotherapy treatment for cancer of the chest, mediastinal area or the neck area is associated with increased risk of cardiovascular disease. With the increasing number of cancer patients and the increased treatment efficiency, the number of cancer survivors is increasing exponentially. The cancer survivors live longer and their long-term follow-up must be considered. The cardiovascular toxicity is mainly associated with the treatment of breast cancer, Hodgkin's lymphoma and head and neck cancer. Radiation-induced cardiovascular effects are insidious and chronic. Their occurrence is linked to numerous factors including the age of the patient at the beginning of the radiotherapy schedule, the number of years following radiotherapy, the doses (and volume) to the heart and the large vessels (coronary and carotid arteries), and the association with the traditional cardiovascular risk factors. Pathophysiological mechanisms remain unclear and, even if similarities with age-related atherosclerosis were established, the specificities of the radiation-induced atherosclerosis for high doses remain to be discovered. For low/moderate doses of ionising radiation, recent epidemiological studies provide evidence of increased risk of cardiovascular pathologies. A better knowledge of the mechanisms associated with the radiation-induced cardiovascular pathologies and the more precise identification of the populations at risk in the future should allow a more effective care of these patients with cardiovascular risk.

    Today, cardiovascular disease is the principal cause of death and hospitalization in Spain, and accounts for an annual healthcare budget of more than 4000 million euros. Consequently, early diagnosis, effective prevention, and the optimum treatment of cardiovascular disease present a significant social and healthcare challenge for the country. In this context, combining all available resources to increase the efficacy and healthcare benefits of scientific research is a priority. This rationale prompted the establishment of the Spanish Cooperative Cardiovascular Disease Research Network, or RECAVA (Red Temática de Investigación Cooperativa en Enfermedades Cardiovasculares), 5 years ago. Since its foundation, RECAVA's activities have focused on achieving four objectives: a) to facilitate contacts between basic, clinical and epidemiological researchers; b) to promote the shared use of advanced technological facilities; c) to apply research results to clinical practice, and d) to train a new generation of translational cardiovascular researchers in Spain. At present, RECAVA consists of 41 research groups and seven shared technological facilities. RECAVA's research strategy is based on a scientific design matrix centered on the most important cardiovascular processes. The level of RECAVA's research activity is reflected in the fact that 28 co-authored articles were published in international journals during the first six months of 2007, with each involving contributions from at least two groups in the network. Finally, RECAVA also participates in the work of the Spanish National Center for Cardiovascular Research, or CNIC (Centro Nacional de Investigación Cardiovascular), and some established Biomedical Research Network Centers, or CIBER (Centros de Investigación Biomédica en RED), with the aim of consolidating the development of a dynamic multidisciplinary research framework that is capable of meeting the growing challenge that cardiovascular disease will present

    Head-out water immersion at thermoneutral temperature (34-35 degrees C) increases cardiac output for a given O2 consumption, leading to a relative hyperperfusion of peripheral tissues. To determine if subjects immersed in water at a colder temperature show similar responses and to explore the significance of the hyperperfusion, cardiovascular functions were investigated (impedance cardiography) on 10 men at rest and while performing exercise on a leg cycle ergometer (delta M = approximately 95 W.m-2) in air and in water at 34.5 degrees C and 30 degrees C, respectively. In subjects resting in water, the cardiac output increased by approximately 50% compared to that in air, mainly due to a rise in stroke volume. The stroke volume change tended to be greater in 30 degrees C water than in 34.5 degrees C water, and this was due to a greater increase in cardiac preload, as indicated by a significantly greater left ventricular end-diastolic volume. Arterial systolic pressure rose slightly during water immersion. Arterial diastolic pressure remained unchanged in 34.5 degrees C water, but it rose in 30 degrees C water. The total peripheral resistance fell 37% in 34.5 degrees C water and 32% in 30 degrees C water. Both in air and in water, mild exercise increased the cardiac output, and this was mainly due to an increase in heart rate. Since, however, the stroke volume increased with water immersion, cardiac output at a given work load appeared to be significantly higher in water than in air. The arterial pressures did not decrease with water immersion, despite a marked reduction in total peripheral resistance. These results suggest that 1) during cold water immersion, peripheral vasoconstriction provides an additional increase in cardiac preload, leading to a further increase in the stroke volume compared to that of the thermoneutral water immersion, 2) the mechanism of cardiovascular adjustment during dynamic exercise is not changed by the persistent increase in cardiac

    The increasing prevalence of congenital heart disease can be attributed to major improvements in diagnosis and treatment. Cardiovascular magnetic resonance imaging plays an important role in the clinical management strategy of patients with congenital heart disease. The development of new cardiovascular magnetic resonance (CMR) techniques allows comprehensive assessment of complex cardiac anatomy and function and provides information about the long-term residual post-operative lesions and complications of surgery. It overcomes many of the limitations of echocardiography and cardiac catheterization. This review evaluates the role of cardiovascular magnetic resonance imaging modality in the management of subject with congenital heart disease (CHD). (authors)

    Thyroid hormones, specifically triiodothyronine (T3), have significant effects on the heart and cardiovascular system. Hypothyroidism, hyperthyroidism, subclinical thyroid disease, and low T3 syndrome each cause cardiac and cardiovascular abnormalities through both genomic and nongenomic effects on cardiac myocytes and vascular smooth muscle cells. In compromised health, such as occurs in heart disease, alterations in thyroid hormone metabolism may further impair cardiac and cardiovascular function. Diagnosis and treatment of cardiac disease may benefit from including analysis of thyroid hormone status, including serum total T3 levels. Copyright © 2014 Elsevier Inc. All rights reserved.

    This paper discusses the possibility of using observer-based approaches for cardiovascular anomalies detection and isolation. We consider a lumped parameter model of the cardiovascular system that can be written in a form of nonlinear state-space representation. We show that residuals that are sensitive to variations in some cardiovascular parameters and to abnormal opening and closure of the valves, can be generated. Since the whole state is not easily available for measurement, we propose to associate the residual generator to a robust extended kalman filter. Numerical results performed on synthetic data are provided.

To explore the effect of depression (D on relative risk (RR of myocardial infarction (MI and stroke for 16 years (1995–2010 in the female population aged 25–64 years from Novosibirsk, Russia. Materials and methods. Under the third screening of the WHO “MONICA-psychosocial” (MOPSY programme, a cohort of women aged 25–64 years (N=560 was surveyed. Women were followed for 16 years for the incidence of MI and stroke (1995–2010. D was measured at the baseline examination by means of test “MOPSY”. Participants having stroke, MI, arterial hypertension, coronary artery diseases and diabetes in their medical history at the baseline were excluded from this analysis. Results. The prevalence of D in women aged 25–64 years was 55.2%. With the growth of D levels, positive self-rated health reduced and almost 100% of those women have complaints about their health, but considered the care of their health insufficient. Women with major D significantly extended negative behavioural habits: smoking and unsuccessful attempts to give up, low physical activity, and less likely to follow a diet (healthy food. Major D associated with high job strain and family stress. Relative risk (RR of MI development in women with D during 16 years of study was higher in 2.53 cases (p<0.05 and risk of stroke was higher in 4.63 cases (p<0.05. Conclusions. The prevalence of D in women aged 25–64 years was >50%. Women with D had a 2.53-fold risk of MI and 4.63-fold risk of stroke during the 16 years of follow-up.

    The fundamental technique of performing percutaneous cardiovascular (CV) interventions has remained unchanged and requires operators to wear heavy lead aprons to minimize exposure to ionizing radiation. Robotic technology is now being utilized in interventional cardiology partially as a direct result of the increasing appreciation of the long-term occupational hazards of the field. This review was undertaken to report the clinical outcomes of percutaneous robotic coronary and peripheral vascular interventions. Areas covered: A systematic literature review of percutaneous robotic CV interventions was undertaken. The safety and feasibility of percutaneous robotically-assisted CV interventions has been validated in simple to complex coronary disease, and iliofemoral disease. Studies have shown that robotically-assisted PCI significantly reduces operator exposure to harmful ionizing radiation without compromising procedural success or clinical efficacy. In addition to the operator benefits, robotically-assisted intervention has the potential for patient advantages by allowing more accurate lesion length measurement, precise stent placement and lower patient radiation exposure. However, further investigation is required to fully elucidate these potential benefits. Expert commentary: Incremental improvement in robotic technology and telecommunications would enable treatment of an even broader patient population, and potentially provide remote robotic PCI.

    Full Text Available The constellation of dyslipidemia (hypertriglyceridemia and low levels of high-density lipoprotein cholesterol, elevated blood pressure, impaired glucose tolerance, and central obesity is now classified as metabolic syndrome, also called syndrome X. In the past few years, several expert groups have attempted to set forth simple diagnostic criteria for use in clinical practice to identify patients who manifest the multiple components of the metabolic syndrome. These criteria have varied somewhat in specific elements, but in general, they include a combination of multiple and metabolic risk factors. The most widely recognized of the metabolic risk factors are atherogenic dyslipidemia, elevated blood pressure, and elevated plasma glucose. Individuals with these characteristics, commonly manifest a prothrombotic state as well as and a proinflammatory state. Atherogenic dyslipidemia consists of an aggregation of lipoprotein abnormalities including elevated serum triglyceride and apolipoprotein B (apoB, increased small LDL particles, and a reduced level of HDL cholesterol (HDL-C. The metabolic syndrome is often referred to as if it were a discrete entity with a single cause. Available data suggest that it truly is a syndrome, ie, a grouping of atherosclerotic cardiovascular disease (ASCVD risk factors, that probably has more than one cause. Regardless of cause, the syndrome identifies individuals at an elevated risk for ASCVD. The magnitude of the increased risk can vary according to the components of the syndrome present as well as the other, non-metabolic syndrome risk factors in a particular person.

    Full Text Available Pomegranate is a source of some very potent antioxidants (tannins, anthocyanins which are considered to be also potent anti-atherogenic agents. The combination of the above unique various types of pomegranate polyphenols provides a much wider spectrum of action against several types of free radicals. Indeed, pomegranate is superior in comparison to other antioxidants in protecting low-density lipoprotein (LDL, “the bad cholesterol” and high-density lipoprotein (HDL, “the good cholesterol” from oxidation, and as a result it attenuates atherosclerosis development and its consequent cardiovascular events. Pomegranate antioxidants are not free, but are attached to the pomegranate sugars, and hence were shown to be beneficial even in diabetic patients. Furthermore, pomegranate antioxidants are unique in their ability to increase the activity of the HDL-associated paraoxonase 1 (PON1, which breaks down harmful oxidized lipids in lipoproteins, in macrophages, and in atherosclerotic plaques. Finally, unique pomegranate antioxidants beneficially decrease blood pressure. All the above beneficial characteristics make the pomegranate a uniquely healthy fruit.

    Molecular imaging strives to visualise processes at the molecular and cellular level in vivo. Understanding these processes supports diagnosis and evaluation of therapeutic efficacy on an individual basis and thereby makes personalised medicine possible. Apoptosis is a well-organised mode of cell suicide that plays a role in cardiovascular diseases (CVD). Apoptosis is associated with loss of cardiomyocytes following myocardial infarction, atherosclerotic plaque instability, congestive heart failure and allograft rejection of the transplanted heart. Thus, apoptosis constitutes an attractive target for molecular imaging of CVD. Our current knowledge about the molecular players and mechanisms underlying apoptosis offers a rich palette of potential molecular targets for molecular imaging. However, only a few have been successfully developed so far. This review highlights aspects of the molecular machinery and biochemistry of apoptosis relevant to the development of molecular imaging probes. It surveys the role of apoptosis in four major areas of CVD and portrays the importance and future perspectives of apoptosis imaging. The annexin A5 imaging protocol is emphasised since it is the most advanced protocol to measure apoptosis in both preclinical and clinical studies. (orig.)

    Cardiovascular diseases remain the leading cause of morbidity and mortality in industrialized and developing countries. In clinical practice, the in-vivo identification of atherosclerotic lesions, which can lead to complications such as heart attack or stroke, remains difficult. Imaging techniques provide the reference standard for the detection of clinically significant atherosclerotic changes in the coronary and carotid arteries. The assessment of the luminal narrowing is feasible, while the differentiation of stable and potentially unstable or vulnerable atherosclerotic plaques is currently not possible using non-invasive imaging. With high spatial resolution and high soft tissue contrast, magnetic resonance imaging (MRI) is a suitable method for the evaluation of the thin arterial wall. In clinical practice, native MRI of the vessel wall already allows the differentiation and characterization of components of atherosclerotic plaques in the carotid arteries and the aorta. Additional diagnostic information can be gained by the use of non-specific MRI contrast agents. With the development of targeted molecular probes, that highlight specific molecules or cells, pathological processes can be visualized at a molecular level with high spatial resolution. In this review article, the development of pathophysiological changes leading to the development of the arterial wall are introduced and discussed. Additionally, principles of contrast enhanced imaging with non-specific contrast agents and molecular probes will be discussed and latest developments in the field of molecular imaging of the vascular wall will be introduced.

    Reengineering, involving the radical redesign of business processes, has been used successfully in a variety of health care settings. In 1994 New York University (NYU) Medical Center (MC) launched its first reengineering team, whose purpose was to redesign the entire process of caring for patients-from referral to discharge-on the cardiovascular (CV) surgery service. REENIGINEERING TEAM: The multidisciplinary CV Surgery Reengineering Team was charged with two goals: improving customer (patient, family, and referring physician) satisfaction and improving profitability. The methodology to be used was based on a reengineering philosophy-discarding basic assumptions and designing the patient care process from the ground up. THE TRANSFER-IN INITIATIVE: A survey of NYU cardiologists, distributed in April 1994, suggested that the organization was considered a difficult place to transfer patients. The team's recommendations led to a new, streamlined transfer-in policy. The average waiting time from when a referring physician requested a patient transfer and the time when an NYUMC physician accepted the transfer decreased from an average of 9 hours under the old system to immediate acceptance. Three customer satisfaction task forces implemented multiple programs to make the service more user friendly. In addition, referrals increased and length of stay decreased, without an adverse impact on the mortality rate. For the first time at NYUMC, a multidisciplinary team was given the mandate to achieve major changes in an entire patient care process. Similar projects are now underway.

    Cardiovascular diseases still rank number one in mortality statistics in the industrialized world. In these countries the five most common causes of death are associated to atherosclerotic changes of the arterial vasculature. Due to its often long lasting treatment and the possible loss of ability to work atherosclerotic disease constitutes an economic factor which should not be disregarded. Thus screening for atherosclerotic disease seems to be reasonable because as known the potential to influence atherosclerotic changes is higher in an early stage of the disease. Not in every case it is possible to cure the disease but sometimes progression can be controlled and decelerated. Imaging of the arterial vasculature was limited to invasive procedures associated with ionizing radiation for a long time. Non-invasive exams like the 'ankle-brachial-index' (ABI) can indicate the presence of PAOD, an exact localization of the pathologic changes is only possible with imaging methods. For cardiac imaging likewise the only non-invasive exams have been ECG and auscultation. Certainly echocardiography is an excellent technique to access cardiac function but it depends very much on both, the examining physician and the patient. MRI constitutes a non-invasive imaging modality without ionizing radiation offering excellent reproducible image quality.

    Cardiovascular disease (CVD), a global epidemic, is responsible for about 30% of all deaths worldwide. While mortality rates from CVD have been mostly declining in the advanced industrialized nations, CVD risk factors, including hypertension, obesity, and diabetes, have been on the increase everywhere. Researchers investigating the social causes of CVD have produced a robust body of evidence documenting the relationships between the work environment and CVD, including through the mechanisms of psychosocial work stressors. We review the empirical evidence linking work, psychosocial stressors, and CVD. These work stressors can produce chronic biologic arousal and promote unhealthy behaviors and thus, increased CVD risk. We offer a theoretical model that illustrates how economic globalization influences the labor market and work organization in high-income countries, which, in turn, exacerbates job characteristics, such as demands, low job control, effort-reward imbalance, job insecurity, and long work hours. There is also a growing interest in "upstream" factors among work stress researchers, including precarious employment, downsizing/restructuring, privatization, and lean production. We conclude with suggestions for future epidemiologic research on the role of work in the development of CVD, as well as policy recommendations for prevention of work-related CVD. © The Author(s) 2016.

    Advances in cardiology, surgical techniques, postoperative care, and medications have improved the chances of long-term survival of the neonatal and pediatric patient with complex congenital cardiac anomalies. Rather than undergoing palliative repair, these children are now frequently taken to the operating room for complete repair. As complete repair becomes the norm, collaborative management and a thorough understanding of the pre and postoperative medications used become essential to the care of these patients. The nurse's ability to understand preop, postop, and management medications is enhanced by an understanding of the principles of cardiac anatomy and physiology, as well as developmental changes in cardiac function. All of these are reviewed. In addition, since the safe and effective administration of these drugs depends on the pediatric intensive care unit (PICU) and neonatal intensive care unit (NICU) nurse's thorough knowledge of these medications and their effects on the cardiovascular system, a brief review of these medications is presented. While new technology and techniques are improving survival rates for children with congenital heart anomalies, it is the postoperative care that these children receive that enhances the patient's survival even more.

    Family patterns of cardiovascular risk behavior are well documented. Significant correlation exists between spouse-spouse, parent-child, and sibling-sibling for cholesterol, high- and low-density lipoprotein, diet, physical activity, and smoking. Family/environmental influences are important in how/if risk and/or preventive behavior is learned. The family matriarch commonly functions as gatekeeper, controlling eating behavior, access to health care, and other patterns. She often acts as menu planner, shopper, and preparer of meals for all family members. She provides information and verbal reinforcement about food and is a powerful model concerning dietary practices. In fact, the mother, as head of household in most single-parent families, may be the only adult model for many children. Because relevance and credibility are the most important characteristics of a behavioral model, parents (especially mothers) are strong models for observational learning by children. Risk factor information and risk reduction activities adopted by the matriarch can be generalized to the entire family if she learns the skills to act as a change agent. Initiation of this process of education and training the matriarch lies with primary care providers for women (Ob-Gyns see most women). By teaching risk reduction to the matriarch as a component of primary care, physician interaction can have a rippling effect.

    Full Text Available Erectile dysfunction (ED is a disorder, which basically can have organic nature, psychological or mixed. ED is not a rarity, and data on its prevalence vary, depending on the areas in which the survey was conducted, followed by a period of research and the definition of the disorder. Most of the men associate ED problem with using drugs, especially cardiac. Even though there is some truth in it, mainly the real causes of ED are not well known even to professionals. Contemporary studies of risk factors for cardiovascular disease, particularly coronary heart disease, have shown the clear link between erectile dysfunction and coronary heart disease, wherein ED first manifests. While, ED precedes the onset of symptoms of coronary heart disease and show to the patient and the physician a clear signal of the direction for conducting diagnostic tests and further treatment in the interest of the health of patients. Endocrine, and neurological disorders, as well as bad habits in addition to the cardiac and kidney disease, lead to ED. It is known also, that the use of cardiac medicines may contribute to ED occurrence. Better knowledge of adverse reactions to medicines, a better understanding of the nature of the disease and the implementation of necessary diagnostic procedures, with a good choice of medication, contribute to solving problems related to ED. If all mentioned do not help, there is the possibility of using new drugs to correct ED.

    Overactive bladder (OAB) syndrome is common urological condition, usually underdiagnosed and difficult to identify. The screening of lower urinary tract symptoms (LUTS) through patient self-administered questionnaires can be useful not only for timely identification of these patients but to implement early interventions for symptoms and their implication in a patients' quality of life (QOL). Our objective was to assess the prevalence of OAB symptoms in patients attending general gynecology units in Barcelona, Spain, through a self-administered screening questionnaire. A cross-sectional, multicenter, observational, epidemiological study was carried out at general gynecology units of ten primary health centers in Barcelona, Spain. The study was conducted during a patient's single visit through self-administered forms. Patients recorded sociodemographic data, medical history and comorbidities, and scored the presence and bother related to specific urological symptoms using the Cuestionario de Autoevaluación del Control de la Vejiga (CACV), the validated Spanish version of the Bladder Control Self-Assessment Questionnaire (B-SAQ). A score ≥6 on the symptoms scale of the CACV was taken as an indicator of suspected OAB. One thousand and four women aged between 18 and 82 participated in the study. The overall prevalence of OAB was 11.8 %. A patient being >50 years was significantly associated with suspected OAB in comparison with the younger group [odds ratio (OR) 3.1 (2.1-4.7); p bladder showed significant association with factors other than age, menopause, and previous urogynecological history, such as high body mass index (BMI) and parity. The estimated prevalence of suspected OAB in patients attending general gynecological services in Barcelona is 11.8 %. Overweight or obese patients and those with three or more children were found to be at elevated risk for developing OAB.

    The continued high rate of cardiovascular morbidity and mortality has attracted wide concern and great attention of pharmaceutical industry. In order to reduce the attrition of cardiovascular drug R&D, it might be helpful recapitulating previous failures and identifying the potential factors to success. This perspective mainly analyses the 30 cardiovascular drugs dropped from clinical development in 2012. Reasons causing the termination of the cardiovascular drugs in the past 5 years are also tabulated and analysed. The analysis shows that the attrition is highest in Phase II trials and financial and strategic factors and lack of clinical efficacy are the principal reasons for these disappointments. To solve the four problems (The 'better than the Beatles' problem, the 'cautious regulator' problem, the 'throw money at it' tendency and the 'basic researchbrute force' bias) is recommended as the main measure to increase the number and quality of approvable products.

    Despite the inherent risks associated with exercise in general and boxing in particular, the sport has had a limited number of catastrophic cardiovascular events. Screening should be based on risks involved and become more extensive with the advancement of the athlete. Anatomic and electrophysiologic risks need to be assessed and may preclude participation with resultant life style and economic complications. There should be adequate preparation for the rare potential cardiovascular complication at all events, with the ability to rapidly assess and treat arrhythmias.

    There is some evidence linking air pollution to cardiovascular morbidity. Our aim was to examine whether there is a correlation between air pollution and cardiovascular morbidity in the city of Trondheim, Norway. We compared the mean daily number of admissions for cardiovascular disease to the St. Olav University hospital on days with relatively low and high levels of PM10 (1993-2001), PM2,5, NO, NO2, SO2, O3, toluene and paraxylene (1998-2001). A time series analysis was carried out to see how day-to-day variations in concentrations of air pollutants correlated with the number of hospitalizations for cardiovascular disease. In the bivariate analysis, the mean daily number of hospitalizations was found to be significantly higher (p < 0.05) on days with NO and NO2 levels above the 80 th percentile (57.6 microg/m3 and 43.1 microg/m3, respectively) than on days with pollutant levels below the 20th percentile (11.3 microg/m3 and 16.9 microg/m3, respectively). Time series analysis did not show any statistically significant correlation between day-to-day variations in air pollution and hospital admissions for cardiovascular disease. The findings regarding NO2 and NO indicate that exposure to gases and/or ultra-small particles from diesel exhaust may influence cardiovascular morbidity.

  11. Would male hormonal contraceptives affect cardiovascular risk?

    Directory of Open Access Journals (Sweden)

    Michael Zitzmann

    2018-01-01

    Full Text Available The aim of hormonal male contraception is to prevent unintended pregnancies by suppressing spermatogenesis. Hormonal male contraception is based on the principle that exogenous administration of androgens and other hormones such as progestins suppress circulating gonadotropin concentrations, decreasing testicular Leydig cell and Sertoli cell activity and spermatogenesis. In order to achieve more complete suppression of circulating gonadotropins and spermatogenesis, a progestin has been added testosterone to the most recent efficacy trials of hormonal male contraceptives. This review focusses on the potential effects of male hormonal contraceptives on cardiovascular risk factors, lipids and body composition, mainly in the target group of younger to middle-aged men. Present data suggest that hormonal male contraception can be reasonably regarded as safe in terms of cardiovascular risk. However, as all trials have been relatively short (< 3 years, a final statement regarding the cardiovascular safety of hormonal male contraception, especially in long-term use, cannot be made. Older men with at high risk of cardiovascular event might not be good candidates for hormonal male contraception. The potential adverse effects of hormonal contraceptives on cardiovascular risk appear to depend greatly on the choice of the progestin in regimens for hormonal male contraceptives. In the development of prospective hormonal male contraception, data on longer-term cardiovascular safety will be essential.

  12. Cardiovascular risk factors and collateral artery formation.

    Science.gov (United States)

    de Groot, D; Pasterkamp, G; Hoefer, I E

    2009-12-01

    Arterial lumen narrowing and vascular occlusion is the actual cause of morbidity and mortality in atherosclerotic disease. Collateral artery formation (arteriogenesis) refers to an active remodelling of non-functional vascular anastomoses to functional collateral arteries, capable to bypass the site of obstruction and preserve the tissue that is jeopardized by ischaemia. Hemodynamic forces such as shear stress and wall stress play a pivotal role in collateral artery formation, accompanied by the expression of various cytokines and invasion of circulating leucocytes. Arteriogenesis hence represents an important compensatory mechanism for atherosclerotic vessel occlusion. As arteriogenesis mostly occurs when lumen narrowing by atherosclerotic plaques takes place, presence of cardiovascular risk factors (e.g. hypertension, hypercholesterolaemia and diabetes) is highly likely. Risk factors for atherosclerotic disease affect collateral artery growth directly and indirectly by altering hemodynamic forces or influencing cellular function and proliferation. Adequate collateralization varies significantly among atherosclerotic patients, some profit from the presence of extensive collateral networks, whereas others do not. Cardiovascular risk factors could increase the risk of adverse cardiovascular events in certain patients because of the reduced protection through an alternative vascular network. Likewise, drugs primarily thought to control cardiovascular risk factors might contribute or counteract collateral artery growth. This review summarizes current knowledge on the influence of cardiovascular risk factors and the effects of cardiovascular medication on the development of collateral vessels in experimental and clinical studies.

  13. Human Cardiovascular Adaptation to Weightlessness

    Science.gov (United States)

    Norsk, Peter

    2011-01-01

    Entering weightlessness (0 G) induces immediately a shift of blood and fluid from the lower to the upper parts of the body inducing expansion of the cardiac chambers (Bungo et al. 1986; Charles & Lathers 1991; Videbaek & Norsk 1997). For many years the effects of sudden 0 G on central venous pressure (CVP) was discussed, and it puzzled researchers that CVP compared to the 1-G supine position decreased during the initial hours of spaceflight, when at the same time left atrial diameter increased (Buckey et al. 1996). By measuring esophageal pressure as an estimate of inter-pleural pressure, it was later shown that this pressure decreases more than CVP does during 0 G induced by parabolic flights (Videbaek & Norsk 1997). Thus, transmural CVP is increased, which distends the cardiac chambers. This unique lung-heart interaction whereby 1) inter-pleural pressure decreases and 2) central blood volume is expanded is unique for 0 G. Because transmural CVP is increased, stroke volume increases according to the law of Frank-Starling leading to an increase in cardiac output, which is maintained increased during months of 0 G in space to levels of some 25% above that of the 1-G seated position (Norsk unpublished). Simultaneously, sympathetic nervous activity is at the level of the upright 1-G posture, which is difficult to explain based on the high stroke volume and decreased blood pressure and systemic vascular resistance. This paradox should be explored and the mechanisms revealed, because it might have implications for estimating the cardiovascular risk of travelling in space.

    Systemic hypertension is one of the main risk factors for cardiovascular disease (CVD). Early diagnosis and treatment of hypertension in childhood can potentially have a significant impact on future adverse outcomes. To investigate the relationship of diastolic (DBP) and systolic blood pressure (SBP) with anthropometric data and area of residence of children in municipalities of Rio Grande do Sul state, Brazil. This is a cross-sectional study of 709 children between six and nine years of age. Blood pressure, weight, height and waist circumference (WC) were measured. Statistical tests had a maximum significance level of 5% (p≤0.05) and the software used was SPSS version 13.0. Obesity was significantly associated with pre-hypertension, and stage 1 and 2 hypertension as assessed by DBP and SBP (≤0.05); high WC was significantly associated with a classification of pre-hypertension and stage 1 hypertension based on DBP and a classification of stage 1 and 2 hypertension based on SBP (≤0.01). Children living in urban areas had significantly higher mean SBP than those living in rural areas. Those with high WC presented higher SBP and DBP compared to children with normal WC. Obese children showed higher mean SBP and DBP compared to those who were overweight or normal weight and mean SBP and DBP also increased with older age and higher mean body mass index and WC.

    Full Text Available Resumen Las estrategias de prevención de las enfermedades cardiovasculares necesitan refinamiento porque su incidencia se reduce muy lentamente. Las funciones de riesgo incorporaron los factores de riesgo clásicos (edad, sexo, consumo de tabaco, diabetes, presión arterial, y perfil lipídico básico en cohortes seguidas generalmente más de 10 años. Son razonablemente precisas para el cribado poblacional del riesgo de enfermedad coronaria exigido en las guías de práctica clínica. Clasifican a los pacientes en niveles de riesgo para concentrar un mayor esfuerzo terapéutico y preventivo en los de mayor riesgo, y en los que el número necesario a tratar y el coste-efectividad son óptimos. Proporcionar el riesgo relativo y de la edad vascular al paciente, le motiva a cumplir seguir tratamientos y estilos de vida. Alrededor del 20% de la población de 35 a 74 años tiene riesgo intermedio y requiere reclasificación a alto o bajo riesgo porque concentra 35% de eventos poblacionales de enfermedad coronaria. Se ensayan nuevos biomarcadores (bioquímicos, genéticos o de imagen para mejorar la precisión de las predicciones. Si los equipos informáticos de los sistemas de salud incorporaran el cálculo automatizado del riesgo se facilitaría la tarea preventiva del personal asistencial.
