Effect of investigation intensity and treatment differences on prostate cancer survivor's physical symptoms, psychological well-being and health-related quality of life: a two country cross-sectional study.

Aim: To investigate effects on men's health and well-being of higher prostate cancer (PCa) investigation and treatment levels in similar populations. Participants: PCa survivors in Ireland where the Republic of Ireland (RoI) has a 50% higher PCa incidence than Northern Ireland (NI). Method: A cross-sectional postal questionnaire was sent to PCa survivors 2–18 years post-treatment, seeking information about current physical effects of treatment, health-related quality of life (HRQoL; EORTC QLQ-C30; EQ-5D-5L) and psychological well-being (21 question version of the Depression, Anxiety and Stress Scale, DASS-21). Outcomes in RoI and NI survivors were compared, stratifying into ‘late disease’ (stage III/IV and any Gleason grade (GG) at diagnosis) and ‘early disease’ (stage I/II and GG 2–7). Responses were weighted by age, jurisdiction and time since diagnosis. Between-country differences were investigated using multivariate logistic and linear regression. Results: 3348 men responded (RoI n=2567; NI n=781; reflecting population sizes, response rate 54%). RoI responders were younger; less often had comorbidities (45% vs 38%); were more likely to present asymptomatically (66%; 41%) or with early disease (56%; 35%); and less often currently used androgen deprivation therapy (ADT; 2%; 28%). Current prevalence of incontinence (16%) and impotence (56% early disease, 67% late disease) did not differ between RoI and NI. In early disease, only current bowel problems (RoI 12%; NI 21%) differed significantly in multivariate analysis. In late disease, NI men reported significantly higher levels of gynaecomastia (23% vs 9%) and hot flashes(41% vs 19%), but when ADT users were analysed separately, differences disappeared. For HRQoL, in multivariate analysis, only pain (early disease: RoI 11.1, NI 19.4) and financial difficulties (late disease: RoI 10.4, NI 7.9) differed significantly between countries. There were no significant between-country differences in DASS-21 or index ED-5D-5L score. Conclusions: Treatment side effects were commonly reported and increased PCa detection in RoI has left more men with these side effects. We recommended that men be offered a PSA test only after informed discussion.

Mobility and satisfaction with lower-limb prostheses and orthoses among users in Sierra Leone: A cross-sectional study

Objectives: To investigate patients' mobility and satisfaction with their lower-limb prosthetic or orthotic device and related service delivery in Sierra Leone; to compare groups of patients regarding type and level of assistive device, gender, area of residence, income; and to identify factors associated with satisfaction with the assistive device and service. Methods: A total of 139 patients answered questionnaires, including the Quebec User Evaluation of Satisfaction with Assistive Technology questionnaire (QUEST 2.0). Results: Eighty-six percent of assistive devices were in use, but half needed repair. Thirty-three percent of patients reported pain when using their assistive device. Patients had difficulties or could not walk at all on: uneven ground (65%); hills (75%); and stairs (66%). Patients were quite satisfied with their assistive device and the service (mean 3.7 out of 5 in QUEST), but reported 886 problems. Approximately half of the patients could not access services. In relation to mobility and service delivery, women, orthotic patients and patients using above-knee assistive devices had the poorest results. The general condition of the assistive device and patients' ability to walk on uneven ground were associated with satisfaction with the assistive devices and service. Conclusion: Patients reported high levels of mobility while using their device although they experienced pain and difficulties walking on challenging surfaces. Limitations in the effectiveness of assistive devices and limited access to follow-up services and repairs were issues desired to be addressed.

School belongingness and mental health functioning across the primary-secondary transition in a mainstream sample: Multi-group cross-lagged analyses

The relationship between school belongingness and mental health functioning before and after the primary-secondary school transition has not been previously investigated in students with and without disabilities. This study used a prospective longitudinal design to test the bi-directional relationships between these constructs, by surveying 266 students with and without disabilities and their parents, 6-months before and after the transition to secondary school. Cross-lagged multi-group analyses found student perception of belongingness in the final year of primary school to contribute to change in their mental health functioning a year later. The beneficial longitudinal effects of school belongingness on subsequent mental health functioning were evident in all student subgroups; even after accounting for prior mental health scores and the cross-time stability in mental health functioning and school belongingness scores. Findings of the current study substantiate the role of school contextual influences on early adolescent mental health functioning. They highlight the importance for primary and secondary schools to assess students' school belongingness and mental health functioning and transfer these records as part of the transition process, so that appropriate scaffolds are in place to support those in need. Longer term longitudinal studies are needed to increase the understanding of the temporal sequencing between school belongingness and mental health functioning of all mainstream students.

Gender, class and the household economy in Scotland in the ‘Age of affluence’

From early 1950s to the early 1970s Britain is said to have experienced an ‘age of affluence’. Whilst material conditions for many households improved in these decades, this detailed examination of budget management processes shows that for many working-class households, these gains were the product of hard work and careful money management. Using oral history methodology, this thesis explores lived experiences of the household economy to illuminate these qualifications to ‘affluence’. In so doing, this thesis advances analysis which considers the relationship between the macro-level economic conditions of affluence and the everyday economic realities of households in the post-war period. The thesis examines the operation of the household economy and shows how working-class households utilised domestic labour, budgeting, paid work, credit and thrift to make ends meet, as well as to achieve ‘affluence’. Further, by exploring these areas of the household economy, this thesis shows that gendered ideology continued to preserve power and material inequalities between men and women. Although considerable change did occur, particularly involvement in the paid labour market, domestic responsibilities continued to be an important focus of women’s identities and the effective performance of these duties by women remained central to the success of the household. This thesis represents a fresh focus on how the exploration of everyday life, including the salience of ideological continuities in shaping experience, can qualify and refine our understanding of twentieth century economic and social change, and contributes to socio-historical understandings of ‘affluence’ and its intersections with the household, gender, and class.

Actividad física, imagen corporal y condiciones de vida. Un abordaje teórico desde los determinantes y la determinación social de la salud

El objetivo de este trabajo fue analizar la construcción social del conocimiento en Actividad física desde dos planteamientos teóricos de la salud centrando el análisis en la relación con la imagen corporal y las condiciones de vida. Se trata de un estudio teórico desde el análisis de contenido de corte narrativo de 98 artículos desarrollado en cinco etapas a través de: rastreo de documentos en bases de datos en el periodo 2000-2014, revisión de artículos, y análisis y hallazgos de significados, sentidos o contenidos. Como hallazgo importante se puede mencionar que en la literatura científica relacionada con la triada Actividad física-imagen corporal-condiciones de vida predomina la construcción del conocimiento a partir de modelos hegemónicos y dominantes que priorizan la intensidad, la frecuencia y el tiempo dedicado a la AF, la estandarización en la comparación de la apariencia física y la medición de elementos materiales en el modo de vivir de las personas, principalmente desde el abordaje de los determinantes sociales de la salud. Se concluye que es necesario revisar las poblaciones que incluyendo en los estudios al estar concentrados el conocimiento en solo unos grupos; así como se hace explícita la necesidad de revisar cuales son los aportes de la Educación Física y otras disciplinas (ciencias sociales) para una mayor comprensión teórica y práctica de la AF.

Estereotipos sobre el envejecimiento según el periodo del desarrollo y el género

Teniendo en cuenta el drástico aumento en Colombia y el mundo de la población adulta mayor la pirámide poblacional se ha invertido. Lo que ha generado que cada vez haya más adultos mayores y la esperanza de vida sea mayor. Motivo por el cual surge la importancia de conocer diversos aspectos del envejecimiento, entre ellos los estereotipos. Adicionalmente hay muy poca investigación relacionada con los estereotipos sobre el envejecimiento según el género y el periodo de desarrollo. Levy (2009) encontró que son los jóvenes quienes tienen más estereotipos negativos sobre el envejecimiento pues estos sienten que la vejez está muy lejos de su realidad actual y no es en una amenaza personal. Por otro lado Bodner, Bergman y Cohen (2012), encontraron que son los hombres quienes tienen más estereotipos negativos sobre el envejecimiento. La presente investigación tuvo como objetivo describir el efecto del periodo del desarrollo y el género en los estereotipos sobre el envejecimiento en 860 adultos colombianos. Se midió la variable de estereotipos sobre el envejecimiento a través del cuestionario de Ramírez y Palacios (2015) y el periodo del desarrollo y el género a través de un cuestionario de datos sociodemograficos. Contrario a lo esperado, los resultados mostraron que no existe relación entre los estereotipos negativos con el género, el periodo del desarrollo, ni en la interacción de estos. En cambio, se encontraron diferencias entre los estereotipos positivos el género y el periodo de desarrollo. Se considera importante continuar realizando investigaciones relacionadas con esta temática pues cada vez son más los adultos mayores y la manera en que nos relacionemos con ellos, va a determinar un mejor proceso de envejecimiento para ellos.

Síntomas y factores ergonómicos asociados con trastornos musculoesqueléticos (TME) en una población de trabajadores administrativos de una empresa de servicios, 2015

Introducción. Los Trastornos Musculoesqueléticos (TME) son lesiones de músculos, tendones, nervios y articulaciones que tienen como principal síntoma el dolor y se presentan con gran frecuencia en trabajos que requieren una actividad física importante o como consecuencia de malas posturas sostenidas durante largos periodos de tiempo. Objetivo: Determinar la prevalencia de síntomas osteomusculares y su asociación con factores ergonómicos en una población de trabajadores administrativos de una empresa de servicios en Bogotá, Colombia, en el año 2015. Método: Se realizó un estudio de corte transversal. Se analizaron datos secundarios correspondientes a una base de datos de una población de 450 trabajadores pertenecientes al área administrativa de una empresa de servicios, de los cuales se incluyeron 150 registros que tenían la información completa de las variables del estudio. Se tuvieron en cuenta variables sociodemográficas, ocupacionales y la presencia de síntomas osteomusculares. Incluyó también el registro de condiciones de la estación de trabajo recolectada mediante inspecciones de puestos de trabajo (registro fotográfico y formato estandarizado para condiciones observadas). Se realizó un análisis descriptivo considerando las medidas de tendencia central para las variables cuantitativas y distribución de frecuencias para las variables cualitativas. Resultados: Predominó el género femenino (56%) dentro de la población estudiada, con una edad media para ambos géneros de 35 años (75%), (DS ± 7.0). El síntoma más frecuentemente reportado fue el dolor en cuello (17%) seguido por dolor en muñeca (11%) y dolor lumbar (8.7%). Del total de los trabajadores evaluados, el 80% correspondió al cargo ejecutivo, que reúne funciones administrativas especializadas complejas y/o de supervisión directa. De la población femenina objeto de estudio el 76% se desempeñaban en el cargo ejecutivo. Las condiciones ergonómicas por mejorar de mayor frecuencia fueron altura y distancia de la pantalla (42%) y cables sueltos (30%). La frecuencia de síntomas fue más alta en el rango de edad de 31 a 45 años. Conclusiones: En este estudio se encontró que los síntomas osteomusculares más frecuentes se ubicaron en el segmento axial (cuello y región lumbar) y en mano y que las condiciones de altura y distancia de la pantalla y cables sueltos presentaron las frecuencias más altas de condiciones por mejorar. Se hace necesaria la implementación de programas de prevención de TME, la vigilancia de casos y la intervención de las condiciones de los puestos de trabajo. Se debe promover la identificación y promoción de conductas saludables dentro del ámbito laboral y la prevención de condiciones que favorezcan la aparición del riesgo biomecánico.

Actitudes hacia la Enfermedad del Alzheimer según el género y la edad de adultos colombianos

La enfermedad de Alzheimer (EA) es la demencia más frecuente y su prevalencia continúa en aumento tanto en Colombia como en el mundo. Esta investigación tuvo como objetivo explorar si las actitudes hacia la EA varían según la edad y género de 450 personas adultas colombianas. Se realizó un estudio exploratorio de corte transversal en el que se aplicó un cuestionario autodiligenciado. Se encontró que efectivamente hay algunas diferencias según la edad y el género en el componente cognoscitivo (creencias y conocimiento) y conductual (intención conductual y conducta) de las actitudes; y diferencias según el género en el componente afectivo. Se concluye que los conocimientos sobre la EA son escasos, que la tristeza es la emoción predominante hacia la EA y que es un tema de interés en el que predomina la idea de que afecta especialmente la memoria. Se discutieron los resultados reconociendo que esta es una aproximación inicial a las actitudes hacia la EA.

Age and Gender Identification using Stacking for Classification⋆ Notebook for PAN at CLEF 2016

This paper presents our approach of identifying the profile of an unknown user based on the activities of known users. The aim of author profiling task of PAN@CLEF 2016 is cross-genre identification of the gender and age of an unknown user. This means training the system using the behavior of different users from one social media platform and identifying the profile of other user on some different platform. Instead of using single classifier to build the system we used a combination of different classifiers, also known as stacking. This approach allowed us explore the strength of all the classifiers and minimize the bias or error enforced by a single classifier.

Cross-correlations between weather variables in Australia

The information on climate variations is essential for the research of many subjects, such as the performance of buildings and agricultural production. However, recorded meteorological data are often incomplete. There may be a limited number of locations recorded, while the number of recorded climatic variables and the time intervals can also be inadequate. Therefore, the hourly data of key weather parameters as required by many building simulation programmes are typically not readily available. To overcome this gap in measured information, several empirical methods and weather data generators have been developed. They generally employ statistical analysis techniques to model the variations of individual climatic variables, while the possible interactions between different weather parameters are largely ignored. Based on a statistical analysis of 10 years historical hourly climatic data over all capital cities in Australia, this paper reports on the finding of strong correlations between several specific weather variables. It is found that there are strong linear correlations between the hourly variations of global solar irradiation (GSI) and dry bulb temperature (DBT), and between the hourly variations of DBT and relative humidity (RH). With an increase in GSI, DBT would generally increase, while the RH tends to decrease. However, no such a clear correlation can be found between the DBT and atmospheric pressure (P), and between the DBT and wind speed. These findings will be useful for the research and practice in building performance simulation.

The mechanical strength of phosphates under friction-induced cross-linking

Purpose: In the present study, we consider mechanical properties of phosphate glasses under high temperatureinduced and under friction-induced cross-linking, which enhance the modulus of elasticity. Design/methodology/approach: Two nanomechanical properties are evaluated, the first parameter is the modulus of elasticity (E) (or Young's modulus) and the second parameter is the hardness (H). Zinc meta-, pyro - and orthophosphates were recognized as amorphous-colloidal nanoparticles were synthesized under laboratory conditions and showed antiwear properties in engine oil. Findings: Young's modulus of the phosphate glasses formed under high temperature was in the 60-89 GPa range. For phosphate tribofilm formed under friction hardness and the Young's modulus were in the range of 2-10 GPa and 40-215 GPa, respectively. The degree of cross-linking during friction is provided by internal pressure of about 600 MPa and temperature close to 1000°C enhancing mechanical properties by factor of 3 (see Fig 1). Research limitations/implications: The addition of iron or aluminum ions to phosphate glasses under high temperature - and friction-induced amorphization of zinc metaphosphate and pyrophosphate tends to provide more cross-linking and mechanically stronger structures. Iron and aluminum (FeO4 or AlO4 units), incorporated into phosphate structure as network formers, contribute to the anion network bonding by converting the P=O bonds into bridging oxygen. Future work should consider on development of new of materials prepared by solgel processes, eg., zinc (II)-silicic acid. Originality/value: This paper analyses the friction pressure-induced and temperature–induced the two factors lead phosphate tribofilm glasses to chemically advanced glass structures, which may enhance the wear inhibition. Adding the coordinating ions alters the pressure at which cross-linking occurs and increases the antiwear properties of the surface material significantly.
