Weight-for-age percentile and its association to community acquired methicillin resistant Staphylococcus aureus among pediatric patients in Houston, TX

BACKGROUND: Weight has been implicated as a risk factor for symptomatic community-acquired methicillin resistant Staphylococcus Aureus (CA-MRSA). Information from Texas Children's Hospital (TCH) in Houston, TX was used to implement a case-control study to assess weight-for-age percentile (WFA), race and seasonal exposure as risk factors. ^ METHODS: A retrospective chart review to collect data from TCH was conducted covering the time period January 1st, 2008 to May 31st, 2011. Cases were confirmed and identified by the infectious disease department and were matched on a 1:1 ratio to controls that were seen by the emergency department for non-infected fractures from June 1st, 2008 to May 31st, 2011. Data abstraction was performed using TCH's electronic medical records (EMR) system (EPIC ®). ^ RESULTS: Of 702 CA-MRSA identified cases, ages 9 to 16.99, 564 (80.3%) had the variable `weight' present in their EMR, were not duplicates and not determined to be outliers. Cases were randomly matched to a pool of available controls (n=1864) according to age and gender, yielding 539 1:1 matched pairs (95.5% case matching success) with a total study sample size, N=1078. Case median age was 13.38 years with the majority being White (66.05%) and male (59.4%). Adjusted conditional logistic regression analysis of the matched pairs identified the following risk factors to presenting with CA-MRSA infection among pediatric patients, ages 9 to 16.99 years: a) Individual weight in the highest (75th-99.9th) WFA quartile (OR=1.36; 95% confidence interval [CI]=1.06-1.74; P= 0.016), b) Infection during summer months (OR: 1.69; 95% CI=1.2-2.38; P= 0.003), c) patients of African American race/ethnicity (OR= 1.48; 95% CI=1.13-1.95; P= 0.004). ^ CONCLUSIONS: Pediatric patients, 9 to 16.99 years of age, in the highest WFA quartile (75th-99.9th), or of African-American race had an associated increased risk of presenting with CA-MRSA infection. Furthermore, children in this population were at a higher risk of contracting CA-MRSA infection during the summer season.^

Exploring the role of social capital influence variables on travel behaviour

This paper explores the potential role of individual trip characteristics and social capital network variables in the choice of transport mode. A sample of around 100 individuals living or working in one suburb of Madrid (i.e. Las Rosas district of Madrid) participated in a smartphone short panel survey, entering travel data for an entire working week. A Mixed Logit model was estimated with this data to analyze shifts to metro as a consequence of the opening of two new stations in the area. Apart from classical explanatory variables, such as travel time and cost, gender, license and car ownership, the model incorporated two “social capital network” variables: participation in voluntary activities and receiving help for various tasks (i.e. child care, housekeeping, etc.). Both variables improved the capacity of the model to explain transport mode shifts. Further, our results confirm that the shift towards metro was higher in the case of people “helped” and lower for those participating in some voluntary activities.

Capital social, capital relacional e innovación: un análisis de su incidencia en el desarrollo del distrito de Arequipa, Perú

El capital social –que según algunos autores contiene también el capital relacional- es el elemento que posibilita que la sociedad se mantenga unida, en otras palabras es el “pegamento social”. El rol de los elementos que le constituyen, y que son en su mayoría inmateriales, ha comenzado a cobrar mayor importancia en los diversos aspectos de la vida, de manera especial en el ámbito económico. Por otro lado, una de las diversas perspectivas que se encargan del desarrollo territorial (Camagni, 2003) ofrece un marco teórico general que engloba en un solo modelo tanto el capital social como el capital relacional y los procesos innovadores; entendiendo este último elemento como aquel que desempeña un papel fundamental en los procesos de crecimiento económico. La ubicación geográfica del presente estudio es la ciudad de Arequipa, que es la segunda en importancia en Perú después de Lima –la ciudad capital-. Arequipa ha experimentado los últimos años importantes índices de crecimiento económico, sin embargo, en muchos aspectos este hecho no ha significado una mejora en la calidad de vida de las personas. El presente estudio tiene por objetivo general acercarse al estado del capital social, del capital relacional y de la innovación en el distrito de Arequipa. Dentro de los objetivos específicos, y en lo referido a la innovación, se busca conocer el estado de la innovación en las organizaciones del distrito y determinar el estado de desarrollo de ésta. En lo respectivo al segundo tema, se busca caracterizar el estado del capital social y del capital relacional y explorar si existen elementos que sean comunes con el estado de la innovación. La metodología se fundamenta en el análisis cualitativo y a través de entrevistas con ciudadanos en lo referido al capital social y al capital relacional. Se hizo, asimismo, un relevamiento con trabajadores de diversas organizaciones sobre el estado de la innovación. Con esta información se obtuvieron resultados que dan cuenta de la riqueza de las relaciones sociales analizadas...

Linking tourism, retirement migration and social capital

A general trend in the study of international retirement migration has been the increased attention paid to the social contacts and network connections of the migrants in both the destination and the origin areas. These studies have examined the extent to which migrants build social relationships with their neighbours and the host society while also maintaining social links with their countries of origin, addressing the central role that leisure travel plays in sustaining increasingly dispersed social networks and maintaining the social capital of these networks and of the individuals involved in them. Using a case study approach to examine British retirement migration to Spain, we explore the relevance of transnational social networks in the context of international retirement migration, particularly the intensity of bidirectional visiting friends and relatives (VFR) tourism flows and the migrants’ social contacts with friends and/or family back in their home country. Building on the concept of social capital and Putnam's distinction between bonding and bridging social capital, we propose a framework for the analysis of the migrants’ international social networks. The results of a study conducted based on a sample of 365 British retirees living in the coast of Alicante (Spain) show both the strength of the retirees’ international bonding social capital and the role of ‘VFR's travel and communication technologies in sustaining the migrants’ transnational social practices and, ultimately, their international bonding social capital. It also provides evidence for the reinforcing links between tourism-related mobility and amenity-seeking migration in later life.
