Sun exposure and protection habits in transplant athletes: an international survey

Background: Transplant recipients are particularly prone to the development of skin cancer, and overexposure to UV radiation during outdoor activities increases the risk of carcinogenesis. Objective: The aim of this study was to analyze sun-related behaviors and knowledge in transplant athletes, examine the equency of sunburns, and explore associations with a history of skin cancer. Materials and methods: Cross-sectional descriptive study. Participants (n = 170) in the XXI World Transplant Games from >50 countries completed a questionnaire on sun protection habits and knowledge, type of transplant, immunosuppressive therapy, and personal history of skin cancer. Results: The most common transplanted organs were the kidney (n = 79), the liver (n = 33), and the heart (n = 31). Overall, 61.3% of athletes had been doing sport for >15 years and 79.5% spent >1–2 h a day outdoors. Fifteen % of athletes had a history of skin cancer. The prevalence of sunburn in the previous year was 28.9%, higher in athletes aged <50 years (37.2%); without a primary school education (58.3%), not taking cyclosporin (32.6%), and athletes who played basketball (75%). The main sun protection measures used were sunscreen (68.9%) and sunglasses (67.3%). Use of a hat or cap was the only measure significantly associated with a reduced prevalence of sunburn. Conclusions: Despite high awareness that sun exposure increases the risk of skin cancer, sunburn was common in transplant athletes. Efforts should be made to strengthen multidisciplinary sun protection education strategies and ensure periodic dermatologic follow-up to prevent sun-induced skin cancer in this population.This work has been supported by the project no.

Energy needs and vulnerability estimation at an urban scale for residential neighbourhoods heating in Madrid (Spain)

Urban areas renovation may lead to problematic situations associated with financing of the works in absence of a detailed analysis of the distribution of resources. An analysis of the needs and the obstacles in achieving buildings refurbishment to improve their energy efficiency must be observed. Buildings requiring energy refurbishment will be those with poor construction quality, not adapted to the new energy efficiency requirements. People with insufficient resources to deal with such actions will inhabit many of them. This paper proposes a model for energy needs assessment at an urban scale with the objective set on the refurbishment of residential buildings neighbourhoods, addressing comfort needs. In this sense, aspects of building energy vulnerability are explored as a prerequisite to the analysis of energy poverty in our cities and neighbourhoods. A methodology to characterize heating needs of urban areas is developed by using statistical data from the Spanish Census of Housing and Population. The superimposition of resulting demand values with demographic data allows introducing socioeconomic criteria in order to locate urban energy efficiency and fuel vulnerability. This information is useful in order to address specific public refurbishment strategies based on the reality of socioeconomic aspects of the neighbourhoods and the state of preservation of buildings

Co2TiO4/reduced graphene oxide nanohybrids for electrochemical sensing applications

For the first time, the synthesis, characterization, and analytical application for hydrogen peroxide quantification of the hybrid materials of Co2TiO4 (CTO) and reduced graphene oxide (RGO) is reported, using in situ (CTO/RGO) and ex situ (CTO+RGO) preparations. This synthesis for obtaining nanostructured CTO is based on a one-step hydrothermal synthesis, with new precursors and low temperatures. The morphology, structure, and composition of the synthesized materials were examined using scanning electron microscopy, X-ray diffraction (XRD), neutron powder diffraction (NPD), and X-ray photoelectron spectroscopy (XPS). Rietveld refinements using neutron diffraction data were conducted to determine the cation distributions in CTO. Hybrid materials were also characterized by Brunauer-Emmett-Teller adsorption isotherms, Scanning Electron microscopy, and scanning electrochemical microscopy. From an analytical point of view, we evaluated the electrochemical reduction of hydrogen peroxide on glassy carbon electrodes modified with hybrid materials. The analytical detection of hydrogen peroxide using CTO/RGO showed 11 and 5 times greater sensitivity in the detection of hydrogen peroxide compared with that of pristine CTO and RGO, respectively, and a two-fold increase compared with that of the RGO+CTO modified electrode. These results demonstrate that there is a synergistic effect between CTO and RGO that is more significant when the hybrid is synthetized through in situ methodology.Fil: Venegas, Constanza J..

Hábitos, actitudes y conocimientos sobre la exposición solar de corredores de fondo en la Costa del Sol

A nivel dermatológico, la elevada exposición solar a radiación ultravioleta asociada a la práctica de actividades deportivas al aire libre, máxime en actividades recreativas de larga duración como son los corredores de fondo, aumenta el fotoenvejecimiento de la piel y la incidencia de cáncer de piel. El propósito del estudio fue evaluar los hábitos, actitudes y conocimientos sobre la exposición solar de corredores de fondo de nuestra comunidad. Se realizó un estudio transversal descriptivo mediante encuesta con un muestreo de conveniencia entre aquellos participantes de las medias maratones populares de Fuengirola y Marbella celebradas en el mes de septiembre del año 2016. En la muestra evaluada se ha hallado una intensa exposición solar realizando actividades al aire libre, asociado ello a una prevalencia de quemaduras solares elevada (uno de cada 2 corredores). Exposure to UV radiation during the practice of sports in the open air is especially high in sustained recreational activities such as long-distance running. UV exposure increases skin photoaging and the incidence of skin cancer. This study aimed to describe habits and attitudes related to sun exposure among long-distance runners in our area of southern Spain as well as to evaluate the runners’ knowledge of exposure. A cross-sectional descriptive study was designed to survey a convenience sample of participants in half marathons in Fuengirola and Marbella in September 2016. We found a high level of sun exposure among participants in this outdoor activity. The prevalence of sunburn was also high, experienced by half of the runners surveyed

Hábitos y conocimientos sobre fotoprotección y factores de riesgo para quemadura solar en corredores de maratones de montaña

Background and objectives: The incidence of skin cancer in our society is growing at an alarming rate due to overexposure to solar UV radiation in recreational and occupational settings. The aim of this study was to evaluate sun exposure and protection attitudes, behaviors, and knowledge among mountain ultramarathon runners and to assess risk factors for sunburn in this population. Material and methods: Cross-sectional survey of runners who participated in the «Gran Trail Aneto-Posets» race in Aragon, Spain. Using a validated questionnaire, we collected data on sociodemographic characteristics, running experience, sunburn in the previous summer, and sun exposure and protection behaviors. We calculated descriptive statistics and performed bivariate and multivariate analyses of associations using history of sunburn as the primary outcome. Statistical significance was set at a p level of less than 0.05. Results: We surveyed 657 runners (72.1% men) with a mean age of 39.71 years; 45.1% reported sunburn in the past year. The most common protective measures used were sunglasses (74.7%), sunscreen (sun protection factor = 15) (61.9%), a hat (52.2%), and other protective clothing (7.4%). Risk factors for sunburn were younger age, low Fitzpatrick skin type (I and II), running for three or more hours a day, and staying in the shade as a protective measure. By contrast, protective factors were use of sunscreen and seeking shade rather than sun at midday (p < 0.001). Conclusions: Sunburn is common among long-distance mountain runners, despite what appears to be adequate sun protection knowledge and behaviors. Targeted strategies are needed to improve sun protection behaviors among mountain runners

Validation of a Questionnaire Designed to Study Knowledge, Attitudes, and HabitsRelated to Sun Exposure Among Young Adults: The CHACES Questionnaire

Las campañas escolares de prevención del cáncer cutáneo han demostrado ser eficaces y costo-efectivas. Su éxito depende de un adecuado dise˜no, basado en la encuestación previa de la población diana (alumnos, profesores y padres). Sin embargo, son escasos los cuestionarios validados en castellano que estudien hábitos y conocimientos sobre exposición solar en infancia, y nulos en la población adultojuvenil. Objetivos: Elaborar y validar un cuestionario que explore las conductas relacionadas con la exposición solar en población adultojuvenil. Metodología: Se elaboraron 2 cuestionarios, dirigidos a población adulta (mayor de 18 a˜nos) y juvenil (11-17 a˜nos), incluyendo datos demográficos, color de piel, fototipo, quemaduras solares, prácticas, actitudes y conocimientos relacionados con la exposición solar. Tras el pilotaje y análisis de validez de contenido, se dise˜nó un estudio de validación en 2 fases: I) Análisis de la validez y consistencia interna de los ítems (estudio trasversal sobre 1.482 adolescentes-adultos, con estudio de validez de constructo [mediante análisis factorial exploratorio] y de consistencia interna [alfa de Cronbach]), II) Estudio de la estabilidad (test-retest sobre 39 sujetos). Resultados: El pilotaje demostró la validez de contenido de sendos cuestionarios. El análisis de los componentes principales reveló 2 componentes en cada dimensión estudiada, explicando más del 50% de la varianza. Todos los ítems mostraron buena correlación entre ellos. Se demostró validez en la fase i (coeficiente alfa de Cronbach entre 0,45-0,8, excepto el área de conocimientos [0,335]) y estabilidad en la fase ii (acuerdo absoluto > 60%).Skin cancer prevention campaigns in schools have been shown to be both effectiveand cost-effective. The success of such programs depends on the use of an appropriate designinformed by a prior survey of the target population (pupils, teachers, and parents). There are,however, very few validated Spanish-language questionnaires designed to study the habits andknowledge of this population with respect to sun exposure in childhood and none designed foruse with a young adult population.Objectives: To construct and validate a questionnaire designed to explore sun exposure beha-viors in a young adult population.Methodology: Two questionnaires were developed, one for adults (18+) and the other for youngadults (11-17); both included demographic information, skin color, Fitzpatrick skin type, andhistory of sunburn as well as questions on knowledge, attitudes and practices related to sunexposure. The content was then piloted and its validity analyzed. The subsequent validationstudy was divided into 2 phases as follows: 1) analysis of the validity and internal consistencyof the items in a cross-sectional study of 1,482 adults and adolescents, using exploratory factoranalysis to test construct validity and Cronbach to measure internal consistency; and 2)evaluation of test-retest reliability in 39 individuals.Results: The pilot study demonstrated the content validity of both questionnaires. Principalcomponent analysis revealed that 2 components in each of the dimensions studied accountedfor over 50% of the variance. A good correlation was found between the items studied. Validitywas demonstrated in the first phase of the analysis with a Cronbach of between 0.45 and 0.8for all components except knowledge (0.335). In the second phase, test-retest reliability wasdemonstrated (absolute agreement > 60%).Conclusions: The psychometric properties of the questionnaire make it a valid and reliable toolfor the study of knowledge, attitudes, and habits with respect to sun exposure in the youngadult school population

Antebrachial microvascular flap for reconstruction of the pelvic limb: case report

Complex defects in the soft tissues of the foot and ankle caused by high-energy trauma, infection, cancer or diabetes require rapid and effective treatment which decreases the risk of infection, bone healing time, hospital stay and number total of surgical approaches. Authors report a clinical case of a 23-year-old female patient who suffers high-energy trauma due to a motorcycle accident which causes exposure of the distal third of the tibia, loss of the tibial joint face, and loss of tissue throughout the region of the malleolus medial of the right pelvic extremity. Tissue transfer to the pelvic limb is performed using left contralateral radial antebrachial free flap as donor area. This case report aims to emphasize the key aspects of the high energy trauma approach by using microvascular flaps, as well as the satisfactory evolution of the patient that directly affects the prognosis for life and function

Status and Recent Results of the Acoustic Neutrino Detection Test System AMADEUS

The AMADEUS system is an integral part of the ANTARES neutrino telescope in the Mediterranean Sea. The project aims at the investigation of techniques for acoustic neutrino detection in the deep sea. Installed at a depth of more than 2000m, the acoustic sensors of AMADEUS are based on piezo-ceramics elements for the broad-band recording of signals with frequencies ranging up to 125kHz. AMADEUS was completed in May 2008 and comprises six "acoustic clusters", each one holding six acoustic sensors that are arranged at distances of roughly 1m from each other. The clusters are installed with inter-spacings ranging from 15m to 340m. Acoustic data are continuously acquired and processed at a computer cluster where online filter algorithms are applied to select a high-purity sample of neutrino-like signals. 1.6 TB of data were recorded in 2008 and 3.2 TB in 2009. In order to assess the background of neutrino-like signals in the deep sea, the characteristics of ambient noise and transient signals have been investigated. In this article, the AMADEUS system will be described and recent results will be presented.Comment: 7 pages, 8 figures.

The ANTARES Telescope Neutrino Alert System

The ANTARES telescope has the capability to detect neutrinos produced in astrophysical transient sources. Potential sources include gamma-ray bursts, core collapse supernovae, and flaring active galactic nuclei. To enhance the sensitivity of ANTARES to such sources, a new detection method based on coincident observations of neutrinos and optical signals has been developed. A fast online muon track reconstruction is used to trigger a network of small automatic optical telescopes. Such alerts are generated for special events, such as two or more neutrinos, coincident in time and direction, or single neutrinos of very high energy.Comment: 17 pages, 9 figures submitted to Astroparticle Physic
