Health-related quality of life in European women following myocardial infarction: A cross-sectional study

Background:Coronary heart disease is a major contributor to women's health problems.Design:Self-perceived social support, well-being and health-related quality of life (HRQL) were documented in the cross-sectional HeartQoL survey of European women one and six months after a myocardial infarction.Methods:European women were recruited in 18 European countries and grouped into four geographical regions (Southern Europe, Northern Europe, Western Europe and Eastern Europe). Continuous socio-demographic variables and categorical variables were compared by age and region with ANOVA and χ(2), respectively; multiple regression models were used to identify predictors of social support, well-being and HRQL.Results:Women living in the Eastern European region rated social support, well-being and HRQL significantly lower than women in the other regions. Older women had lower physical HRQL scores than younger women. Eastern European women rated social support, well-being and HRQL significantly lower than women in the other regions. Prediction of the dependent variables (social support, well-being and HRQL) by socio-demographic factors varied by total group, in the older age group, and by region; body mass index and managerial responsibility were the most consistent significant predictors.

A Swiss paradox? Higher income inequality of municipalities is associated with lower mortality in Switzerland.

It has long been surmised that income inequality within a society negatively affects public health. However, more recent studies suggest there is no association, especially when analyzing small areas. This study aimed to evaluate the effect of income inequality on mortality in Switzerland using the Gini index on municipality level. The study population included all individuals >30 years at the 2000 Swiss census (N = 4,689,545) living in 2,740 municipalities with 35.5 million person-years of follow-up and 456,211 deaths over follow-up. Cox proportional hazard regression models were adjusted for age, gender, marital status, nationality, urbanization, and language region. Results were reported as hazard ratios (HR) with 95 % confidence intervals. The mean Gini index across all municipalities was 0.377 (standard deviation 0.062, range 0.202-0.785). Larger cities, high-income municipalities and tourist areas had higher Gini indices. Higher income inequality was consistently associated with lower mortality risk, except for death from external causes. Adjusting for sex, marital status, nationality, urbanization and language region only slightly attenuated effects. In fully adjusted models, hazards of all-cause mortality by increasing Gini index quintile were HR = 0.99 (0.98-1.00), HR = 0.98 (0.97-0.99), HR = 0.95 (0.94-0.96), HR = 0.91 (0.90-0.92) compared to the lowest quintile. The relationship of income inequality with mortality in Switzerland is contradictory to what has been found in other developed high-income countries. Our results challenge current beliefs about the effect of income inequality on mortality on small area level. Further investigation is required to expose the underlying relationship between income inequality and population health.

Coping with drought

People in arid and semi-arid regions face difficult living conditions, increasingly aggravated by extended periods of drought and advancing desertification. However, the populations of arid and semi-arid regions can also rely on the great potential for innovation and adaptation that they have developed over centuries of living in these environments. This brochure presents the reality of people living in the world’s arid and semi-arid regions, and shows how SDC supports them in developing innovations and improving their livelihoods.

Capability of E-Bike Tourism in Switzerland

AIM OF PAPER AND RESEARCH QUESTIONS The primary aim of this investigation was to examine, if tourism in Switzerland can be stimulated by focusing on e-bike offers. Switzerland is an attractive and manifold country for bike tourism. However, there are plenty of hilly and steep areas, where the topography is quite demanding and cycling is predestined to ambitious sportsperson. Less performance-oriented bike tourists are possibly discouraged by the challenges of the landscape. E-bikes seem to be a reasonable alterna-tive to enable less trained person to attend bike tours in steeper regions as well as to keep heterogeneous groups together. E-bikes are already popular in Switzerland for daily routes as the journey to work, but they are not very common in the tour-istic context. The presented investigation evaluates the current standing of supply and demand for e-bike tourism and asks for opportunities and threats in the future development. LITERTURE REVIEW The existing frameworks to analyse capability in the field of sport tourism are limited, because of the broad variation of sports and tourism types. Still several conceptions are valuable to evaluate the opportunities of e-bike tourism in Switzer-land. According to Higham and Hinch (2009) the potential of touristic products and destinations always depends on the interaction among the factors place, people and activity. Standeven and de Knop (1999) support this position by identify-ing the experience of place as a key component of the sport tourism experience. Bull (2005) assumes that place not only affects experience. In his opinion, the specific spatially located resources are even crucial for the existence of nature sports. He identifies four factors determining the attraction of touristic products or destination, as physical characteristics, accessibility and infrastructural arrangements, political and economic resources as well as cultural and perceptual aspects. Concerning the demand side (people) the contemporary research is guided by an individual psychological focus delivering mainly results about motives and the decision making process (e.g. Görtz & Hürten, 2011). RESEARCH DESIGN AND DATA ANALYSIS The presented study is based on a between method triangulation, consisting of qualitative interviews with important stake-holders on the supply side and a cross sectional survey on the demand side. Qualitative interviews were conducted with the first provider of touristic e-bike routes and with the manager of the leading e-bike rental company in Switzerland. The interviews were evaluated by qualitative content analysis according to Mayring (2008). The survey covered a randomized sample of 748 adult persons and focused on interests and needs of potential consumers. The concluding potentials analy-sis combined the results of the interviews and the survey with the findings of literature research. As central outcome the strengths, weaknesses, opportunities and threats were evaluated and presented by SWOT-analysis. RESULTS Results showed that the development of e-bike tourism in Switzerland was not initiated by tourism promoter, but by an innovative e-bike producer. However, also for the manufacturer the fit between landscape (place), product (activity) and visitors (people) was the crucial criterion. The first e-bike tours were offered in a demanding and rural region, in order that the experience of place was able to promote a positive overall experience. Due to the success of the first touristic e-bike products, several tourism regions started to extend their portfolio with e-bike offers. To date a nationwide network for signalised e-bike tours, rental stations and changing stations for rechargeable batteries is established. Despite the attractive offer, the demand is only moderate. The obtained results of the consumer survey pointed at a certain barrier to use e-bikes for tourism activities. The most substantial barrier is the missing affinity for bike tourism in general. Another notable group considering themselves as “fit enough for normal bike tourism”. Nevertheless 55% of the respondent are interested in tour-istic e-bike products. Looking only at people with e-bike tourism experience, even 92% are interested in further activities. DISCUSSION AN CONCLUSION The current study findings are encouraging because they suggest a superior suitability and an attractive level of e-bike tourism products in Switzerland. The results of the consumer survey indicate an increasing demand for e-bike tourism. The investigation also points at some risks, as the rivalry for bike tourism or the raised safety hazard because of the increased driving speed. Summing up, the results support the conclusion, that e-bike tourism will become more important in the com-ing years. However, to reach the goal relevant trends as the requirement for customised offers must be considered and marketing activities are supposed to be extended. REFERENCES Bull, C. (2005).

From gene to protein: Investigating the disease etiology of retinitis pigmentosa

Retinitis pigmentosa (RP) is a name given to a group of inherited retinal dystrophies that lead to progressive photoreceptor degeneration, and thus, visual impairment. It is evident at both the clinical and the molecular level that these are heterogeneous disorders, with wide variation in severity, mode of inheritance, and phenotype. The genetics of RP are not simple; the disease can be inherited in dominant, recessive, X-linked, and digenic modes. Autosomal dominant RP (adRP) results from mutations in at least ten mapped loci, but there may be dozens of genetic loci where mutations can cause RP. To date, there are over a hundred genes known to cause retinal degenerative diseases, and less than half of these have been cloned (RetNet). Among the dozens of retinitis pigmentosa loci known to exist, only a few have been identified and the remainders are inferred from linkage studies. Today, the genes for seven of the twelve-adRP loci have been identified, and these are rhodopsin, peripherin/RDS, NRL, ROM1, CRX, RP13 and RP1. My research projects involved a combination of the continued search for genes involved in retinal dystrophies, as well the investigation into the role of peripherin/RDS and RP1 in the disease etiology of autosomal dominant RP. ^ Most of the mutations leading to inherited retinal disorders have been identified in predominately retina expressed genes like rhodopsin, peripherin/RDS, and RP1. Expressed sequence tags (ESTs) that were retina-specific were culled from sequence databases and, together with laboratory analysis, were analyzed as potential candidate genes for retinal dystrophies. Thirteen of the fifty-five identified retina-specific ESTs mapped to within candidate regions for inherited retinopathies. One of these is RP1L1, a homologue of RP1 and a potential cause of adRP. ^ Once a disease-associated gene has been identified, elucidating the role of that gene in the visual process is essential for understanding what happens when the process is defective as it is in adRP. My next projects involved investigating the role of a novel 5′ donor +3 splice site mutation on the mRNA of peripherin/RDS in adRP affected individuals, and comparative sequencing in RP1 to define conserved regions of the protein. Comparative sequencing is a powerful way to delineate critical regions of a sequence because different regions of a gene have different functions, and each region is subject to different levels of functional or structural constraints. Establishing a framework of conserved domains is beneficial not only for structural or functional studies, but can also aid in determining the potential effects of mutations. With the completion of sequencing of human genome, and other organisms such as Saccharomyces cerevisiae, Caenorhabditis elegans , and Drosophila, the facility of comparative sequencing will only increase in the future. Comparative sequencing has already become an established procedure for pinpointing conserved regions of a protein, and is an efficient way to target regions of a protein for experimental and/or evolutionary analysis. ^

Radiocarbon dates of sediments from ODP Site 161-976

Multiproxy paleoenvironmental records (pollen and planktonic isotope) from Ocean Drilling Program Site 976 (Alboran Sea) document rapid ocean and climate variations during the last glacial that follow the Dansgaard-Oeschger climate oscillations seen in the Greenland ice core records, thus suggesting a close link of the Mediterranean climate swings with North Atlantic climates. Continental conditions rapidly oscillated through cold-arid and warm-wet conditions in the course of stadial-interstadial climate jumps. At the time of Heinrich events, i.e., maximum meltwater flux to the North Atlantic, western Mediterranean marine microflora and microfauna show rapid cooling correlated with increasing continental dryness. Enhanced aridity conceivably points to prolonged wintertime stability of atmospheric high-pressure systems over the southwestern Mediterranean in conjunction with cooling of the North Atlantic.

Efecto de diferentes niveles de salinidad sobre el crecimiento de Atriplex lampa

El ensayo se llevó a cabo en invernáculo con plántulas de Atriplex lampa (zampa) de 30 días. Se realizaron 5 tratamientos, con 20 repeticiones cada uno. El modelo experimental fue completamente aleatorizado. Durante 28 días se efectuaron riegos cada 5 días con soluciones de Murashige & Skoog (MS) y distintas concentraciones finales de NaCl: T1 (sin NaCl) y T2, T3, T4 y T5 con 200, 400, 600 y 800 mM NaCl respectivamente. Se midió: a) la altura de las plantas, a partir del cuello, a los 7, 14, 21 y 28 días; b) el peso seco -por separado- del vástago y la raíz y potencial agua, al finalizar el ensayo (día 28) en muestras tomadas antes del amanecer en plantas cortadas a la altura del cuello. El NaCl adicionado redujo el crecimiento de Atriplex lampa respecto de T1. Dicho efecto se acentuó con el aumento de la concentración salina y la cantidad de días bajo tratamiento. La materia seca aérea producida disminuyó a medida que aumentaba la salinidad del suelo. La producción de materia seca radical no mostró diferencias significativas (P > 0.05) entre tratamientos. Por lo tanto, la zampa podría adaptarse a suelos salinos con crecimiento aceptable, constituyendo una alternativa forrajera valiosa para regiones áridas y salinas.

Virus del papiloma humano : presentación oral y su relación con el carcinoma espinocelular

El virus del papiloma humano (VPH) (HPV en su sigla en inglés) es un virus ADN con especial afinidad por células epiteliales, tanto cutáneas como mucosas, que incluyen el epitelio del cérvix, región anogenital y orofaríngea. Existen más de 120 subtipos de VPH subdivididos en dos grupos según su bajo o alto riesgo de inducir actividad oncogénica. En cavidad oral la manifestación clínica benigna de la infección es el papiloma plano.Sin embargo, un 12% de los carcinoma~ o rofaríngeos son causados por este virus. Se ha demostrado que la infección por VPH tiene un papel independiente como factor de riesgo para el desarrollo de carcinoma espinocelular en cavidad oral.

Deep drilling of glaciers: Russian projects in the Arctic (1975-1995)

The data collection "Deep Drilling of Glaciers: Soviet-Russian projects in Arctic, 1975-1995" was collected by the following basic considerations: - compilation of deep (>100 m) drilling projects on Arctic glaciers, using data of (a) publications; (b) archives of IGRAN; (c) personal communication of project participants; - documentation of parameters, references. Accuracy of data and techniques applied to determine different parameters are not evaluated. The accuracy of some geochemical parameters (up to 1984 and heavy metalls) is uncertain. Most reconstructions of ice core age and of annual layer thickness are discussed; - digitizing of published diagrams (in case, when original numerical data were lost) and subsequent data conversion to equal range series and adjustment to the common units. Therefore, the equal-range series were calculated from original data or converted from digitized chart values as indicated in the metadata. For the methodological purpose, the equal-range series obtained from original and reconstructed data were compared repeatedly; the systematic difference was less then 5-7%. Special attention should be given to the fact, that the data for individual ice core parameters varies, because some parameters were originally measured or registered. Parameters were converted in equal-range series using 2 m steps; - two or more parameter values were determined, then the mean-weighted (i.e. accounting the sample length) value is assigned to the entire interval; - one parameter value was determined, measured or registered independently from the parameter values in depth intervals which over- and underlie it, then the value is assigned to the entire interval; - one parameter value was determined, measured or registered for two adjoining depth intervals, then the specific value is assigned to the depth interval, which represents >75% of sample length ; if each of adjoining depth intervals represents <75% of sample length, then the correspondent parameter value is assigned to both intervals of depth. This collection of ice core data (version 2000) was made available through the EU funded QUEEN project by S.M. Arkhipov, Moscow.

Producciones identitarias y relaciones interculturales en el periurbano platense

El presente artículo se inscribe en una serie de trabajos focalizados en experiencias migratorias y construcción de identidades y alteridades étnico-nacionales que venimos realizando tanto en el área periurbana de producción hortícola como en el casco urbano de la ciudad de La Plata. (1) En ellos abordamos aspectos de la inserción local de los migrantes -en especial con respecto al caso boliviano- desde distintos ejes analíticos como son la adscripción étnico-nacional, el trabajo, el género, la participación institucional, la construcción de categorías de alteridad con respecto a los migrantes por parte de sujetos, instituciones y medios de comunicación locales, el uso de medios como estrategia de identificación / afirmación / participación desde los propios migrantes. En el caso específico de la migración boliviana a Argentina, tanto al área plenamente urbana como a la rural periurbana -en donde adquiere especial importancia-, constituye un fenómeno estructurado y con características propias, situación reforzada por el subempleo en las áreas de economía campesina en Bolivia y la demanda de algunos sectores de la economía argentina, como actualmente el de la construcción urbana y el de la producción hortiflorícola periurbana. En tal sentido el tema se constituye en referente privilegiado para destacar los aspectos dinámicos de la ciudad y su región. En este contexto expondremos algunas reflexiones conceptuales y resultados de trabajo de campo referidos a la auto y hetero demarcación de la pertenencia étnico-nacional como espacio identificatorio en las dimensiones de trabajo y género.

Cooperativas, crédito estatal y desarrollo rural. Una primera aproximación a su estudio en el caso de Córdoba (1940- 1960)

En este artículo se ponen en relación los resultados del estudio sobre los incentivos materiales del accionar cooperativo con las tendencias de la economía agraria y familiar, en Córdoba, desde la década de 1940 a 1960.Los nuevos mecanismos de comercialización colectiva, en donde participaba la entidad de segundo grado FACA (Federación Argentina de Cooperativas Argentinas) y a la cual estaban asociadas las cooperativas primarias adheridas a la Federación Agraria Argentina y, el Estado - a través del Instituto Argentino de Promoción al Intercambio- aumentaban el poder de negociación de los productores rurales. Por otro lado, las políticas crediticias provinciales fueron -ya desde el inicio del período considerado- favorables al sector agrario y cooperativo. Ambos factores -planteamos- actuaron como incentivos materiales al fortalecimiento de la economía familiar. Para analizar la economía agraria de los productores familiares trabajamos con datos censales a nivel micro-regional (departamento Tercero Arriba) y contextualizamos este estudio con resultados de otras investigaciones sobre las regiones pampeanas cordobesa y nacional. Trabajamos también las prácticas cooperativas con memorias, balances y actas de las entidades de la micro-región y, realizamos una primera aproximación a las políticas crediticias provinciales a las cooperativas, a través de fuentes producidas y existentes en el Banco Provincia de Córdoba.

Pore-water chemistry of abyssal Arabian Sea surface sediments

Benthic fluxes and pore-water compositions of silicic acid, nitrate and phosphate were investigated for surface sediments of the abyssal Arabian Sea during four cruises (1995-1998). Five sites located in the northern (NAST), western (WAST), central (CAST), eastern (EAST), and southern (SAST) Arabian Sea were revisited during intermonsoonal periods after the NE- and SW-Monsoon. At these sites, benthic fluxes of remineralized nutrients from the sediment to the bottom water of 36-106, 102-350 and 4-16 mmol/m**2/yr were measured for nitrate, silicic acid and phosphate, respectively. The benthic fluxes and pore-water compositions showed a distinct regional pattern. Highest fluxes were observed in the western and northern region of the Arabian Sea, whereas decreasing fluxes were derived towards the southeast. At WAST, the general temporal pattern of primary production, related to the NE- and SW-Monsoon, is reflected by benthic fluxes. In contrast, at sites NAST, SAST, CAST, and EAST a temporal pattern of fluxes in response to the monsoon is not obvious. Our results reveal a clear coupling between the general regional pattern of production in surface waters and the response of the benthic environment, as indicated by the flux of remineralized nutrients, though a spatially differing degree of decoupling during transport and remineralization of particulate organic matter and biogenic opal was observed. This has to be taken into account regarding budget calculations and paleoceanographic topics.
