Risk Consumption: Children and Online Gaming. The Problem of “Responsible Gambling”

Online gambling is a popular activity among adolescents. However, there has been a notable increase in the number of young people who suffer or are on the verge of pathological gambling. We review the impact of online gambling on young people and discuss the desiderability of the concept of “gambling responsibly” in order to alert of their risks and effectively prevent access to minors. The main factors associated with pathological gambling are the age of start, the family environment, the infl uence of advertising, the consumption of stimulants, and the attitudes of the peer group. Both the government and the gaming industry itself should consider these factors and develop comprehensive plans that ensure a safe and controlled model game. In this context, advertising must take into account criteria of consumer protection knowing that even if they are not allowed, children can easily have access to online gambling. All agents involved, including public and social agents, must provide mechanisms for prevention and awareness of a problem that arouses little social consciousness and excessive carelessness.

What is this thing called Historical Archaeology?

Historical archaeology, in its narrow temporal sense -as an archaeology of the emergence and subsequent evolution of the Modern world- is steadily taking pace in Spanish academia. This paper aims at provoking a more robust debate through understanding how Spanish historical archaeology is placed in the international scene and some of its more relevant particularities. In so doing, the paper also stresses the strong links that have united historical and prehistorical archaeology since its inception, both in relation to the ontological, epistemological and methodological definition of the first as to the influence of socio-political issues in the latter. Such reflection is partly a situated reflection from prehistory as one of the paper’s authors has been a prehistorian for most of her professional life.

Evaluación y modificación de los conocimientos actitudes y prácticas de los estudiantes de primer año de la Escuela de Derecho de la Universidad de Cuenca frente a las infecciones de transmisión sexual ITS y VIH/SIDA

Con un diseño cuasi-experimental, modalidad antes y después, se incluyó 99 estudiantes a los que se midió los conocimientos, actitudes y prácticas antes de la intervención educativa y tres meses después de ella. Resultados: en los conocimientos hubo un incremento promedio de 5.67 a 7.22; las actitudes de igual manera 6.57 a 8.17; a diferencia de las prácticas no tuvieron una variación con un promedio de 4.7, en el grupo intervenido. La media de edad de inicio de las relaciones sexuales fue de 15.6 ± 2.2 años; con respecto al número de personas con las que tuvieron relaciones sexuales en los 3 últimos meses fue de 1.2 ± 0.8 en la preintervención, en la post intervención fue de 1.3 ± 0.9, lo que nos dio una diferencia de medias estadísticamente significativa (P menor que 0,05). Según la Escala de Autoeficacia para prevenir el SIDA, en todas las 27 preguntas el nivel de autoeficacia mejoró en el grupo intervenido de manera significativa. Se concluyó que la intervención educativa diseñada elevó los conocimientos, mejoró las actitudes y la autoeficacia de los estudiantes frente a las ITS/VIH/SIDA; y se dio una modificación beneficiosa en las prácticas de prevención; a diferencia de las prácticas de riesgo donde no encontramos modificación

Población anidante e impacto en la pesca artesanal del cormorán neotropical Phalacrocorax brasilianus (Suliformes:Phalacrocoracidae), en el sitio Ramsar Cerrón Grande, El Salvador.

El cormorán neotropical (Phalacrocorax brasilianus) es una especie de ave acuática abundante en los humedales de El Salvador. La depredación de peces que realiza en los ecosistemas acuáticos, está generando un conflicto con los pescadores que asocian la disminución de la pesca con la conducta depredadora del ave. Entre abril de 2010 a febrero de 2011, se realizó una investigación tendiente a conocer el estado de la población de P. brasilianus en el Sitio Ramsar Embalse Cerrón Grande, El Salvador. El estudio se desarrolló por medio de cinco censos y recolecta de ejemplares, estos últimos se utilizaron para analizar el contenido estomacal. El máximo de ejemplares contabilizados fue de 28,063 individuos y 3,000 parejas reproductoras. Se recolectaron 266 ejemplares, de los cuales, 207 contenían peces en sus estómagos,cuyo peso individual varío de 2 a 307 g ±52 g.Se encontró un total de 1,078 ejemplares de peces correspondiente a diez especies, cuatro de ellas obtuvieron los mayores valores de abundancia: bagre (Cathorops steindachneri)con 29%, seguido por guapote (Parachromis managuensis) con 25%, tilapia (Oreochromis niloticus) con 22% y plateada (Astianax aeneus, Roeboides bouchellei) con 21%. ABSTRACT: The neotropical cormorant (Phalacrocorax brasilianus) is a species of waterfowl abundant in the wetlands of El Salvador. Fish predation on aquatic ecosystems is generating a conflict with fishermen that associating declining fishing with predatory behavior of this bird. From April 2010 to February 2011, an investigation was conducted aimed at knowing the state of the population of P. brasilianus in the Ramsar wetland Cerron Grande, El Salvador. The study was conducted through counting and collecting of birds, to analyze the stomachic contents. The maximum recorded was 28.063 individuals and 3,000 breeding pairs. 266 birds were collected, on 207 it found fish in their stomachs, whose individual weight ranged from 2-307 g ± 52 g. A total of 1,078 fish specimens was found, from ten species, four of them obtained the highest values of abundance: bagre (Cathorops steindachneri) with 29%, followed by guapote (Parachromis managuensis) with 25%,tilapia (Oreochromis niloticus) with 22% and plateada (Astyanax aeneus, Roeboides bouchellei) with 31%.

Renal effects and vascular reactivity induced by Tityus serrulatus venom

Tityus serrulatus, popularly known as yellow scorpion, is one of the most studied scorpion species in South America and its venom has supplied some highly active molecules. The effects of T. serrulatus venom upon the renal physiology in human showed increased renal parameters, urea and creatinine. However, in perfused rat kidney the effects were not tested until now. Isolated kidneys from Wistar rats, weighing 240-280 g, were perfused with Krebs-Henseleit solution containing 6% (g weight) of previously dialysed bovine serum albumin. The effects of T. serrulatus venom were studied on the perfusion pressure (PP), renal vascular resistance (RVR), urinary flow (UF), glomerular filtration rate (GFR), sodium tubular transport (%TNa+), potassium tubular transport (%TK+) and chloride tubular transport (%TCl-). Tityus serrulatus venom (TsV; 10 mu g/mL) was added to the system 30 min after the beginning of each experiment (n = 6). This 30 min period was used as an internal control. The mesenteric bed was perfused with Krebs solution kept warm at 37 T by a constant flow (4 mL/min), while the variable perfusion pressure was measured by means of a pressure transducer. The direct vascular effects of TsV (10 mu g/mL/min; n=6), infused at a constant rate (0.1 mL/min), were examined and compared to the infusion of the vehicle alone at the same rate. TsV increased PP (PP30'= 127.8 +/- 0.69 vs PP60' = 154.2 +/- 14 mmHg*, *p < 0.05) and RVR (RVR30' = 6.29 +/- 0.25 vs RVR60' = 8.03 +/- 0.82 mmHg/mL g(-1) min(-1)*, *p < 0.05), decreased GFR (GFR(30') =0.58 +/- 0.02 vs GFR(60') = 0.46 +/- 0.01 mL g(-1) min(-1)*, *p < 0.05) and UF (UF30' = 0.135 +/- 0.001 vs UF60' = 0.114 +/- 0.003 mL g(-1)min(-1)*, *p < 0.05). Tubular transport was not affected during the whole experimental period (120 min). on the other hand, the infusion of TsV (10 mu g/mL/min) increased the basal perfusion pressure of isolated arteriolar mesenteric bed (basal pressure: 74.17 +/- 3.42 vs TsV 151.8 +/- 17.82 mmHg*, *p < 0.05). TsV affects renal haemodynamics probably by a direct vasoconstrictor action leading to decreased renal flow. (c) 2005 Elsevier Ltd. All rights reserved.

Are we teaching our students what they need to know about ageing? Results from the National Survey of Undergraduate Teaching in Ageing and Geriatric Medicine

Introduction - Learning about ageing and the appropriate management of older patients is important for all doctors. This survey set out to evaluate what medical undergraduates in the UK are taught about ageing and geriatric medicine and how this teaching is delivered. Methods – An electronic questionnaire was developed and sent to the 28/31 UK medical schools which agreed to participate. Results – Full responses were received from 17 schools. 8/21 learning objectives were recorded as taught, and none were examined, across every school surveyed. Elder abuse and terminology and classification of health were taught in only 8/17 and 2/17 schools respectively. Pressure ulcers were taught about in 14/17 schools but taught formally in only 7 of these and examined in only 9. With regard to bio- and socio- gerontology, only 9/17 schools reported teaching in social ageing, 7/17 in cellular ageing and 9/17 in the physiology of ageing. Discussion – Even allowing for the suboptimal response rate, this study presents significant cause for concern with UK undergraduate education related to ageing. The failure to teach comprehensively on elder abuse and pressure sores, in particular, may be significantly to the detriment of older patients.

An exploration of treatment burden and patient capacity in people with stroke

Background and aims: Advances in modern medicine have led to improved outcomes after stroke, yet an increased treatment burden has been placed on patients. Treatment burden is the workload of health care for people with chronic illness and the impact that this has on functioning and well-being. Those with comorbidities are likely to be particularly burdened. Excessive treatment burden can negatively affect outcomes. Individuals are likely to differ in their ability to manage health problems and follow treatments, defined as patient capacity. The aim of this thesis was to explore the experience of treatment burden for people who have had a stroke and the factors that influence patient capacity. Methods: There were four phases of research. 1) A systematic review of the qualitative literature that explored the experience of treatment burden for those with stroke. Data were analysed using framework synthesis, underpinned by Normalisation Process Theory (NPT). 2) A cross-sectional study of 1,424,378 participants >18 years, demographically representative of the Scottish population. Binary logistic regression was used to analyse the relationship between stroke and the presence of comorbidities and prescribed medications. 3) Interviews with twenty-nine individuals with stroke, fifteen analysed by framework analysis underpinned by NPT and fourteen by thematic analysis. The experience of treatment burden was explored in depth along with factors that influence patient capacity. 4) Integration of findings in order to create a conceptual model of treatment burden and patient capacity in stroke. Results: Phase 1) A taxonomy of treatment burden in stroke was created. The following broad areas of treatment burden were identified: making sense of stroke management and planning care; interacting with others including health professionals, family and other stroke patients; enacting management strategies; and reflecting on management. Phase 2) 35,690 people (2.5%) had a diagnosis of stroke and of the 39 co-morbidities examined, 35 were significantly more common in those with stroke. The proportion of those with stroke that had >1 additional morbidities present (94.2%) was almost twice that of controls (48%) (odds ratio (OR) adjusted for age, gender and socioeconomic deprivation; 95% confidence interval: 5.18; 4.95-5.43) and 34.5% had 4-6 comorbidities compared to 7.2% of controls (8.59; 8.17-9.04). In the stroke group, 12.6% of people had a record of >11 repeat prescriptions compared to only 1.5% of the control group (OR adjusted for age, gender, deprivation and morbidity count: 15.84; 14.86-16.88). Phase 3) The taxonomy of treatment burden from Phase 1 was verified and expanded. Additionally, treatment burdens were identified as arising from either: the workload of healthcare; or the endurance of care deficiencies. A taxonomy of patient capacity was created. Six factors were identified that influence patient capacity: personal attributes and skills; physical and cognitive abilities; support network; financial status; life workload, and environment. A conceptual model of treatment burden was created. Healthcare workload and the presence of care deficiencies can influence and be influenced by patient capacity. The quality and configuration of health and social care services influences healthcare workload, care deficiencies and patient capacity. Conclusions: This thesis provides important insights into the considerable treatment burden experienced by people who have had a stroke and the factors that affect their capacity to manage health. Multimorbidity and polypharmacy are common in those with stroke and levels of these are high. Findings have important implications for the design of clinical guidelines and healthcare delivery, for example co-ordination of care should be improved, shared decision-making enhanced, and patients better supported following discharge from hospital.

Elevación transitoria de TSH neonatal asociada a factores de riesgo de parto pretérmino

Introducción: La hipotiroxinemia es una alteración transitoria frecuente en el prematuro que resuelve sin medicación, es importante conocer los factores que se asocian con esta alteración para disminuir el tratamiento inoportuno y el aumento de costos en atención en salud que puede implicar un diagnóstico errado de hipotiroidismo congénito. Por medio de este estudio se evaluó la asociación entre elevación transitoria de la TSH neonatal y algunas variables asociadas a parto pretérmino en pacientes atendidos en la Clínica Materno Infantil Colsubsidio nacidos entre Enero 2014 a Abril de 2015. Metodología: Se realizó un estudio de casos y controles, analítico, retrospectivo. Los casos fueron prematuros con elevación de TSH sin hipotiroidismo congénito, los controles fueron prematuros con TSH normal, seleccionados de manera aleatoria 70 casos, 140 controles con una relación 1:2. Se realizaron asociaciones mediante prueba de chi cuadrado y análisis multivariado para controlar factores de confusión. Resultados: La edad gestacional promedio para casos fue 34.6±1.8, para controles 34.2±2.4. Ambas poblaciones fueron comparables. Los factores con resultados estadísticamente significativos fueron: Pielonefritis (p 0.04), hipertensión inducida por el embarazo (p 0.00), presencia de anemia (p 0.02) y embarazo múltiple (p0.03). Los resultados de regresión logística establecieron que la pielonefritis, hipertensión y anemia son factores de riesgo con resultados estadísticamente significativos. Discusión: Los resultados permitieron documentar que existen factores de riesgo para prematurez, como la pielonefritis, anemia materna e hipertensión inducida por el embarazo, que influyen en los valores de TSH de cordón umbilical que no necesariamente conllevan al desarrollo de hipotiroidismo congénito

Análisis del concepto de liderazgo y sus aplicaciones en el contexto empresarial

El presente trabajo se realizó con el objetivo de tener una visión completa de las teorías del liderazgo, teniendo de este una concepción como proceso y poder examinar las diversas formas de aplicación en las organizaciones contemporáneas. El tema es enfocado desde la perspectiva organizacional, un mundo igualmente complejo, sin desconocer su importancia en otros ámbitos como la educación, la política o la dirección del estado. Su enfoque tiene que ver con el estudio académico del cual es la culminación y se enmarca dentro de la perspectiva constitucional de la Carta Política Colombiana que reconoce la importancia capital que tienen la actividad económica y la iniciativa privada en la constitución de empresas. Las diversas visiones del liderazgo han sido aplicadas de distintas maneras en las organizaciones contemporáneas y han generado diversos resultados. Hoy, no es posible pensar en una organización que no haya definido su forma de liderazgo y en consecuencia, confluyen en el campo empresarial multitud de teorías, sin que pueda afirmarse que una sola de ellas permita el manejo adecuado y el cumplimiento de los objetivos misionales. Por esta razón se ha llegado a concebir el liderazgo como una función compleja, en un mundo donde las organizaciones mismas se caracterizan no solo por la complejidad de sus acciones y de su conformación, sino también porque esta característica pertenece también al mundo de la globalización. Las organizaciones concebidas como máquinas que en sentido metafórico logran reconstituirse sus estructuras a medida que están en interacción con otras en el mundo globalizado. Adaptarse a las cambiantes circunstancias hace de las organizaciones conglomerados en permanente dinámica y evolución. En este ámbito puede decirse que el liderazgo es también complejo y que es el liderazgo transformacional el que más se acerca al sentido de la complejidad.
