    The Salud con Hyland's Project: Comienzo Saludable, Familia Sana [Health With Hyland's Project: Healthy Start, Healthy Family],was developed to provide education and support to Latina mothers regarding healthy infant feeding practices and maternal health. The promotora-delivered intervention was comprised of two charlas (educational sessions) and a supplemental, culturally and linguistically relevant infant feeding and care rolling calendar. Results indicate that the intervention increased intention to breastfeed exclusively, as well as to delay infant initiation of solids by 5 to 6 months. Qualitative feedback identified barriers to maternal and child health education as well as highlighted several benefits of the intervention.

    Introducción Estudios internacionales demuestran que existe un patrón diferenciado de salud y una disparidad en la atención sanitaria entre personas con discapacidad intelectual (DI) y población general. Objetivo Obtener datos sobre el estado de salud de las personas con DI y compararlos con datos de población general. Pacientes y métodos Se utilizó el conjunto de indicadores de salud P15 en una muestra de 111 sujetos con DI. Los datos de salud encontrados se compararon según el tipo de residencia de los sujetos y se utilizó la Encuesta Nacional de Salud 2006 para comparar estos datos con los de la población general. Resultados La muestra con DI presentó 25 veces más casos de epilepsia y el doble de obesidad. Un 20% presentó dolor bucal, y existió una alta presencia de problemas sensoriales, de movilidad y psicosis. Sin embargo, encontramos una baja presencia de patologías como la diabetes, la hipertensión, la osteoartritis y la osteoporosis. También presentaron una menor participación en programas de prevención y promoción de la salud, un mayor número de ingresos hospitalarios y un uso menor de los servicios de urgencia. Conclusiones El patrón de salud de las personas con DI difiere del de la población general, y éstas realizan un uso distinto de los servicios sanitarios. Es importante el desarrollo de programas de promoción de salud y de formación profesional específicamente diseñados para la atención de personas con DI, así como la implementación de encuestas de salud que incluyan datos sobre esta población.

    En el presente artículo se da a conocer una estrategia de intervención llevada a cabo con adultos mayores en la comuna de Paredones, sexta región de Chile, con posterioridad al terremoto y tsunami del 27 de febrero 2010 en Chile, en el contexto de una investigación sobre fortalezas y vulnerabilidades desplegadas por este grupo etario, con posterioridad a un desastre natural. Se presenta una descripción del desarrollo metodológico de la intervención y de los sustentos teóricos y conceptuales en los que se basa. Como resultado de este proceso, se propone una estrategia que trabaje a través de la identificación de las propias experiencias y fortalezas de los sujetos. De tal forma se minimizan los efectos negativos de los determinantes sociales de la salud (como la edad y el lugar de residencia) en contexto de crisis; permitiendo a los adultos mayores fortalecer sus recursos individuales y colectivos, en pro de su bienestar psicosocial.

    El estigma relacionado con el VIH/SIDA continúa siendo un obstáculo para la prevención primaria y secundaria del VIH. Las consecuencias para las personas que viven con la enfermedad han sido muy documentadas y continúan siendo una gran preocupación para las personas que proveen servicios de salud y para aquellas que investigan el tema. Estas consecuencias son preocupantes cuando el estigma emana de profesionales de la salud porque se puede limitar el acceso a los servicios. Uno de los principales obstáculos para la investigación del estigma relacionado con el VIH en Puerto Rico es la falta de instrumentos cuantitativos para evaluar las manifestaciones del estigma entre profesionales de la salud. El objetivo principal de este estudio fue desarrollar y probar las propiedades psicométricas de una escala sobre el estigma relacionado con el VIH/SIDA culturalmente apropiada para personas que proveen servicios de salud puertorriqueñas y desarrollar una versión corta de la escala que pudiera usarse en escenarios clínicos con tiempo limitado. El instrumento desarrollado estuvo basado en evidencia cualitativa recopilada entre profesionales y estudiantes de profesiones de la salud puertorriqueños/as (n=80) y administrado a una muestra de 421 profesionales de la salud en adiestramiento. La escala contenía 12 dimensiones del estigma relacionado con el VIH/SIDA. El análisis cuantitativo corroboró 11 de ellas, teniendo como resultado un instrumento con validez y confiabilidad satisfactoria. Estas dimensiones, a su vez, fueron subcomponentes de un factor de estigma general superior. PMID:20333258

    "Arte con Salud" is an HIV/AIDS prevention intervention tailored for Puerto Rican women who have sex with men. The intervention curriculum was refined through a community-academic collaboration between Taller Salud, the UPRCayey Campus, and the UCC-School of Medicine, subsided in 2012-13 by PRCTRC. The collaboration has been crucial to validate the impact of using art as a tool to facilitate sexual negotiation skills and safer sexual practices among adult women have sex with men participating in HIV prevention education. This article describes the vision, valley, victory phases endured to establish a community-academia partnership based on the CPPR framework as an effective mean to implement a randomized controlled trial intervention (RCT). We also discuss the barriers, outcomes, and lessons learned from this partnership. Some of the identified solutions include: setting goals to secure funding, regular meetings, and the inclusion of undergraduate level students to assist in the implementation of the intervention. These solutions helped to build trust among the community and academic partners. As a result of this collaboration, a total of 86 participants were enrolled and 5 competitive research grants have been submitted. The community-academic collaboration was essential in order to build a solid research infrastructure that addresses the complexities of HIV prevention education among groups of Puerto Rican women.

    RESUMEN El estigma relacionado al VIH/SIDA continúa afectando la prestación de servicios de salud y el bienestar físico y mental de las personas con VIH/SIDA (PVS). Recientemente la literatura científica ha señalado la importancia de comprender las manifestaciones de estigma más allá de las interacciones individuales. Por tal razón, investigaciones recientes en y fuera de Puerto Rico enfatizan la importancia de entender cómo factores socio-estructurales (FSE) influyen en los procesos de estigmatización social. Con el propósito de examinar los FSE que influyen en las manifestaciones de estigma relacionado al VIH/SIDA, realizamos y analizamos nueve grupos focales compuestos por hombres y mujeres en tratamiento para el VIH/SIDA que habían tenido experiencias estigmatizantes. Los participantes identificaron FSE relacionados a las manifestaciones de estigma, tales como el uso de viviendas especializadas, descentralización de los servicios de salud y el desarrollo de protocolos administrativos excluyentes en los servicios de salud. Los resultados demuestran la importancia de considerar los FSE en el desarrollo e implementación de intervenciones dirigidas a la población. PMID:24639599

    Hispanic women suffer from high rates of cardiometabolic risk factors and an increasingly disproportionate burden of cardiovascular disease (CVD). Particularly, Hispanic women with limited English proficiency suffer from low levels of CVD knowledge associated with adverse CVD health outcomes. Thirty-two predominantly Spanish-speaking Hispanic women completed, Vivir Con un Corazón Saludable (VCUCS), a culturally tailored Spanish language-based 6-week intensive community program targeting CVD health knowledge through weekly interactive health sessions. A 30-question CVD knowledge questionnaire was used to assess mean changes in CVD knowledge at baseline and postintervention across five major knowledge domains including CVD epidemiology, dietary knowledge, medical information, risk factors, and heart attack symptoms. Completion of the program was associated with a statistically significant (p < 0.001) increase in total mean CVD knowledge scores from 39 % (mean 11.7/30.0) to 66 % (mean 19.8/30.0) postintervention consistent with a 68 % increase in overall mean CVD scores. There was a statistically significant (p < 0.001) increase in mean knowledge scores across all five CVD domains. A culturally tailored Spanish language-based health program is effective in increasing CVD awareness among high CVD risk Hispanic women with low English proficiency and low baseline CVD knowledge.

    Existe estigma relacionado al VIH. A las personas con VIH/SIDA-PCVS se les viola sus derechos y obstaculiza su bienestar mental/físico. Profesionales de la salud-PS son fuente de apoyo primordial, sin embargo estos/as le estigmatizan. Es útil adiestrar a PS en relación al estigma social. Implantamos la intervención para reducir el estigma relacionado al VIH/SIDA con 507 estudiantes de medicina. Resultó ser una intervención efectiva, hubo reducción en los niveles de estigma a partir de nuestra intervención y diferencias significativas con el grupo control (p≤.05). Generar espacios de adiestramiento para atender el estigma relacionado al VIH/SIDA es pertinente para la psicología comunitaria porque colaboramos en la reducción de actitudes estigmatizantes que afectan adversamente la prevención de nuevas infecciones, la adherencia al tratamiento antirretroviral y la calidad de vida.

    In Peru, the industry's development has made economic improvements but at the same time, it has had a major impact on the health of the workers; for that reason, it was necessary to generate control mechanisms. So, in 1940 it was created the Departmento de Higiene Industrial, which in 1956 was changed to Instituto de Salud Ocupacional, but it was deactivated in 1994. However, in 2001 it reappeared into the Ministerio de Salud organizational structure with the name of Instituto de Salud Ocupacional "Alberto Hurtado Abadía". Actually, it is the Centro Nacional de Salud Ocupacional y Protección del Ambiente para la Salud (CENSOPAS), organ of the Instituto Nacional de Salud which continues working in synergy with other institutions and sectors, making research to protect the health of exposed persons (workers and community) to contamination and risks associated with economic activities.

    2007-12-01

    The Agua Salud Project utilizes the Panama Canal's central role in world commerce to focus global attention on the ecosystem services provided by tropical forests. It will be the largest field experiment of its kind in the tropics aimed at quantifying the environmental services (water, carbon, and biodiversity) provided by tropical forests. The Agua Salud Watershed is our principal field site. This watershed and the headwaters of several adjacent rivers include both protected mature forests and a wide variety of land uses that are typical of rural Panama. Experiments at the scale of entire catchments will permit complete water and carbon inventories and exchanges for different landscape uses. The following questions will be addressed: (1) How do landscape treatments and management approaches affect ecosystem services such as carbon storage, water quality and quantity, dry- season water supply, and biodiversity? (2) Can management techniques be designed to optimize forest production along with ecosystem services during reforestation? (3) Do different tree planting treatments and landscape management approaches influence groundwater storage, which is thought to be critical to maintaining dry-season flow, thus insuring the full operation of the Canal during periods of reduced rainfall and severe climatic events such as El Niño. In addition we anticipate expanding this project to address biodiversity, social, and economic values of these forests.

    2009-01-01

    Resumen Las profesiones de la salud tienen un papel social dual. Por un lado, velan por el mantenimiento de la salud de la población protegiendo el bien común. Por el otro, dictaminan las formas saludables, y por lo tanto socialmente apropiadas, de ser, actuar y pensar. Este último papel, está más ligado al control social de la población que a una preocupación altruista hacia la misma. A través de esta supervisión y control, se construyen los sujetos a los cuales todos/as debemos aspirar a ser para gozar de aceptación social. Los/as profesionales de la salud han jugado un rol protagónico en dicho proceso, siendo los agentes que delimitan y definen lo que es enfermo vs. saludable, útil vs. inútil, apropiado vs. inapropiado. En el caso de la epidemia del VIH, este esfuerzo se ha hecho cada vez más vigente ya que estos/as profesionales juegan un papel importante en el tratamiento de las personas que viven con VIH/SIDA (PVVS). Sin embargo, su función está plasmada de definiciones que sirven para criminalizar a las PVVS. El objetivo de este estudio fue explorar la manera en que una muestra de profesionales de la salud en Puerto Rico construyen a las PVVS. Con este propósito, entrevistamos 80 profesionales de la salud y estudiantes de estas profesiones. Estas entrevistas fueron grabadas, transcritas y sometidas a un análisis de discurso. Los resultados reflejaron que según las personas participantes: 1) la PVVS no es una persona “normal” o funcional bajo los estándares sociales debido a que su salud no se los permite, 2) representa una carga para la sociedad incluyendo familiares, amigos/as, el mundo del trabajo, e incluso para el gobierno, 3) debe ser vigilada porque representa un riesgo para la persona seronegativa que es descrita como saludable y productiva, y 4) necesita que su salud y conducta sexual sean controladas por vía legal y/o por las personas que representan las instituciones sociales, como lo son los/as profesionales de la salud

    El objetivo fue identificar incentivos de atracción y retención en zonas rurales y distantes de Ayacucho, Perú. Fueron realizadas entrevistas en profundidad con 80 médicos, enfermeras, obstetras y técnicos (20 por grupo) de las zonas más pobres y con 11 funcionarios. No existen políticas sistemáticas de atracción y retención de personal de salud en Ayacucho. Los principales incentivos, en orden de importancia, fueron mejoras salariales, oportunidades de formación y capacitación, estabilidad laboral y nombramiento, mejoras en infraestructura y equipos, e incremento del personal. Se mencionaron también mejoras en la vivienda y alimentación, mayor cercanía con la familia y reconocimiento por el sistema de salud. Existen coincidencias y singularidades entre los distintos grupos sobre los incentivos clave para estimular el trabajo rural, que deben considerarse al diseñar políticas públicas. Las iniciativas del Estado deben comprender procesos rigurosos de monitoreo y evaluación, para asegurar que las mismas tengan el impacto deseado. PMID:22488318

    Objetivos. Buscamos cuantificar la manera en que los efectos socioeconómicos, demográficos, geográficos y de atención de salud explican las disparidades raciales en las tasas de bajo peso al nacer y prematuridad en Brasil. Métodos. Utilizamos una muestra de 8 949 niños nacidos entre 1995 y el 2009 en 15 ciudades y 7 provincias de Brasil. Nos centramos en las disparidades en la prevalencia de bajo peso al nacer (< 2 500 g) y prematuridad (< 37 semanas de gestación) en recién nacidos de ascendencia solo africana o mezclada con otras ascendencias y de ascendencia solo europea. Usamos un modelo de descomposición para cuantificar la contribución de los factores conceptualmente pertinentes a esas disparidades. Resultados. El modelo permitió explicar entre 45% y 94% de las disparidades en cuanto al bajo peso al nacer y entre 64% y 94% de las disparidades en cuanto a la prematuridad entre los grupos de ascendencia africana y de ascendencia europea. Las diferencias en el uso de atención prenatal y en la ubicación geográfica fueron los factores más importantes, seguidos por las diferencias socioeconómicas. El modelo permitió explicar la mayoría de las disparidades en los recién nacidos de ascendencia africana mezclada y parte de las disparidades en los de ascendencia solo africana. Conclusiones. En las políticas públicas para mejorar la salud infantil se deben abordar las diferencias en cuanto a la atención prenatal y la ubicación geográfica a fin de reducir las disparidades en materia de salud entre los recién nacidos de ascendencia africana y los de ascendencia europea en Brasil.

    2009-01-01

    El proceso de estigmatización asume una devaluación de la persona debido a una característica o marca que haya sido identificada socialmente y que permita que se le describa como diferente. Desde que se desató la epidemia del VIH/SIDA, vivir con la enfermedad ha sido señalado de manera social como una marca estigmatizante. Las manifestaciones de dicha estigmatización se han documentado entre profesionales de la salud. Este estigma puede afectar los servicios de salud que las personas que viven con VIH/SIDA reciben de estos profesionales. Los objetivos de esta investigación fueron explorar: 1) la percepción que tienen estudiantes y profesionales de la salud sobre su nivel de competencia para ofrecer servicios a personas que viven con VIH/SIDA, 2) las opiniones de éstos sobre el tipo de adiestramiento profesional recibido y la necesidad del mismo, y 3) la manifestación de actitudes estigmatizantes como indicadores de necesidad de adiestramiento profesional. La muestra total del estudio estuvo compuesta por 80 de diversas profesiones de la salud. Los resultados reflejan que algunos/as de los/as participantes han recibido formación en VIH pero ésta no ha sido suficiente para contrarrestar las nociones estigmatizantes. Discutimos las implicaciones de los resultados para investigaciones futuras y el desarrollo de intervenciones con vías de minimizar las nociones estigmatizantes en los escenarios de salud.

    The Nam Con Son basin is the largest oil and gas bearing basin in Vietnam, and has a number of producing fields. The history of studies in the basin can be divided into four periods: Pre-1975, 1976-1980, 1981-1989, and 1990-present. A number of oil companies have carried out geological and geophysical studies and conducted drilling activities in the basin. These include ONGC, Enterprise Oil, BP, Shell, Petro-Canada, IPL, Lasmo, etc. Pre-Tertiary formations comprise quartz diorites, granodiorites, and metamorphic rocks of Mesozoic age. Cenozoic rocks include those of the Cau Formation (Oligocene and older), Dua Formation (lower Miocene), Thong-Mang Cau Formation (middle Miocene), Nam Con Son Formation (upper Miocene) and Bien Dong Formation (Pliocene-Quaternary). The basement is composed of pre-Cenozoic formations. Three fault systems are evident in the basin: north-south fault system, northeast-southwest fault system, and east-west fault system. Four tectonic zones can also be distinguished: western differentiated zone, northern differentiated zone, Dua-Natuna high zone, and eastern trough zone.

    Resumen Las minorías sexuales y de identidad de género en Guatemala son afectadas de manera desproporcionada por el VIH y otras infecciones transmitidas sexualmente (ITS). Sin embargo, poco se sabe de los factores que contribuyen al riesgo de infección en estas minorías. Investigadores de Estados Unidos y Guatemala quisimos informarnos sobre las necesidades de salud sexual e identificar características de programas de prevención de VIH/ITS para estas minorías. Llevamos a cabo 8 grupos focales con hombres gay, bisexuales y personas transgénero y entrevistas en profundidad con líderes comunitarios. Utilizamos el Método Comparativo Constante para analizar las transcripciones. Identificamos 24 factores que influyen en la salud sexual y 16 características de programas para reducir el riesgo de VIH/ITS en estas poblaciones. La identificación de factores de conductas sexuales de riesgo y de características de programas potencialmente efectivos ofrece gran potencial para desarrollar intervenciones que contribuyan a reducir el riesgo de infección por VIH/ITS en estas minorías en Guatemala.

    Introducción: en apoyo a la problemática de sobrepeso y obesidad en México, en el 2010 se publicó el Acuerdo Nacional para la Salud Alimentaria. A nivel escolar, los comodatarios se consideraron fundamentales para cumplir con ciertos compromisos. El objetivo de esta intervención fue capacitar a comodatarios de los Establecimientos de Consumo Escolar (ECE) en cuanto a los criterios establecidos en los “Lineamientos Generales para el Expendio y Distribución de Alimentos en Planteles de Educación Básica.” Métodos: participaron 13 ECE en San Luis Potosí. Con base en un diagnóstico inicial, se diseñó un curso-taller de 5 sesiones. Se evaluaron conocimientos en materia alimentaria al inicio y al final de las sesiones. Se obtuvo el porcentaje de apego en cuanto a higiene general, preparación y distribución de alimentos, al inicio, al mes y a los dos meses postintervención. Resultados: los comodatarios presentaron pocos conocimientos en los objetivos que persigue el “Acuerdo” en grupos y combinación de alimentos así como en lectura de etiquetas; con cambios significativos en los dos últimos tras la intervención. El porcentaje inicial de cumplimiento en higiene general fue del 60 %, con un incremento de casi 20 % postcapacitación. La preparación y distribución de alimentos no presentaron cambios significativos. Conclusiones: los comodatarios adquirieron conocimientos sobre los lineamientos que debe cubrir un ECE, sin ponerlos en práctica, dado el impacto que ello implica en su economía.

    For underserved and disenfranchised communities in the United States, affordable, effective health care can be nearly inaccessible, which often leads to the exclusion of these communities from relevant medical information and care. Barriers to care are especially salient in minority communities, where language, traditions and customs, socioeconomics, and access to education can serve as additional roadblocks to accessing health care information and services. These factors have contributed to a national health disparity crisis that unnecessarily places some communities in a vulnerable position without adequate prevention and treatment opportunities. One solution to the exclusion some communities face in the health care system may be the promotores de salud (PdS)/community health worker (CHW), an approach to culturally competent health care delivery whose popularity in the mainstream health care system has been steadily growing in recent decades. Known by a wide variety of names and broad in the spectrum of health issues they address, the PdS/CHW serves as cultural brokers between their own community and the formal health care system and can play a crucial role in promoting health and wellness within their community. This annotated bibliography was created to educate the reader about the history, definition, key features, utility, outcomes, and broad potential of the CHW approach in a variety of populations. Intended to serve as a reference point to a vast body of information on the CHW/PdS approach, this document is a resource for those wishing to effect change in the disparities within the health care system, and to improve the access to, quality, and cost of health care for underserved patients and their communities. Promotores de Salud is a Spanish term that translates to Health Promoter. A female health worker may be referred to as a Promotora, a male as a Promotor, and the plural of both is Promotores. For the purposes of this bibliography, the terms community

    The U.S. Public Health Service recommends that all women in the United States capable of becoming pregnant consume 400 μg of folic acid daily to reduce their risk of having a pregnancy affected by a neural tube defect (NTD). However, disparities exist in the consumption of folic acid, with Hispanic women having lower rates of folic acid consumption than non-Hispanic white women. A community-based feasibility study was designed to assess the utility of the promotora de salud model to promote consumption of multivitamins containing folic acid for the prevention of NTDs among Spanish-speaking Hispanic women in North Carolina. The study consisted of an educational intervention given by a promotora (a lay, community health worker), with data collection occurring at baseline and four months post-intervention to measure changes in knowledge and behavior. Overall, 52% (n=303) of participants completed all components of the study. Self-reported daily multivitamin consumption increased from 24% at baseline to 71% four months post-intervention. During the same time frame, awareness of folic acid increased from 78% to 98% and knowledge of the role of folic acid in the prevention of birth defects increased from 82% to 92%. The results of this study indicate that the promotora de salud model may be effective in reaching a subpopulation of women with the folic acid message. Additional studies with larger population sizes are warranted to validate these findings.

    ABSTRACT Objective: to perform the translation and cultural adaptation of the document named Marco Regional de Competencias Esenciales en Salud Pública para los Recursos Humanos en Salud de la Región de las Américas (Regional Framework of Core Competencies in Public Health for Health Human Resources in the Region of Americas) from Spanish to Brazilian Portuguese. Method: a methodological study comprising the following phases: authorization for translation; initial translation; synthesis of translations and consensus; back-translation and formation of an expert committee. Result: in the translation of domain names, there was no difference in 66.7% (N = 4); in the translation of domain description and competencies there were divergences in 100% of them (N = 6, N = 56). A consensus of more than 80% was obtained in the translation and improvement in the expert committee by the change of words and expressions for approximation of meanings to the Brazilian context. Conclusion: the translated and adapted document has the potential of application in research, and use in the practice of collective/public health care in Brazil. PMID:28591302

    The fourth Tuberculosis (TB) Symposium, held during the Cuba Salud 2015 International Convention, highlighted advancements in research on TB and Mycobacterium tuberculosis (Mtb) by interdisciplinary teams from academic and federal institutions in Cuba, Colombia, Mexico, and the Dominican Republic. Delegates focused on the targets presented in the World Health Organization End TB Strategy for 2016-2035 and elaborated on four primary themes: 1) attention to vulnerable populations such as immunocompromised individuals, health care workers, and residents of long-term institutions such as prisons and nursing homes; 2) identification of active and latent TB cases through contact investigations; 3) spread and control of drug-resistant Mtb strains; and 4) advancements in the development of novel vaccines or "booster" immunizations. This international TB forum served as a platform for experts in diverse disciplines in these Latin American countries to discuss challenges faced by TB research and control programs, proposing novel research initiatives and promoting collaborative teamwork strategies for TB elimination. In solidarity, collaborative efforts in TB control require identification of symptomatic individuals, rapid diagnostic testing for TB, drug susceptibility assays on Mtb strains, and management that provide universal and gratuitous access to directly observed short-course therapy.

    U.S. childhood obesity has reached epidemic proportions, with one third of children overweight or obese. Latino children have some of the highest obesity rates, a concern because they are part of the youngest and fastest-growing U.S. minority group. Unfortunately, scarce research data on Latinos hinders the development and implementation of evidence-based, culturally appropriate childhood obesity interventions. In response, the Salud America! network conducted a national Delphi survey among researchers and stakeholders to identify research priorities to address Latino childhood obesity and compare differences by occupation and race or ethnicity. The resulting first-ever National Latino Childhood Obesity Research Agenda provides a framework to stimulate research and collaboration among investigators, providers, and communities, and inform policy makers about the epidemic's seriousness and specific needs for priority funding. The agenda ranks family as the main ecological level to prevent Latino childhood obesity--followed by community, school, society, and individual-and ranks top research priorities in each level.

    Increasingly, funders expect that public health researchers will include policy contributions as outcomes. Lack of agreement as to what constitutes a policy contribution of research provides little conceptual or implementation guidance to researchers who lack policy training, as well as to evaluators called on to assess "good" policy contribution. This study applies a previously developed policy framework to explore potential policy contributions from research conducted by 20 principal investigators of Salud America!, the Robert Wood Johnson Foundation's (RWJF) Research Network to Prevent Obesity Among Latino Children. The literature-driven "Policy Contribution Spectra" served as the conceptual framework to jointly develop 20 cases of potential policy contribution. Data collection included document reviews and interviews. Data analysis included within- and cross-case analyses, member checking, data triangulation, and expert reviews. Plotting all 20 projects on the Policy Contribution Spectra showed projects have the potential to contribute to policy across intervention types (e.g., needs assessment or applied research); levels (e.g., local or state); timing (e.g., before or after policy enactment); and outcomes (e.g., process action or health benefits). Potential policy contributions on the Spectra framework were shown as multidirectional; multilayered (e.g., simultaneous state and local action); and multidimensional (e.g., multiple strategies aimed at multiple stakeholders). The Policy Contribution Spectra adds a useful policy lens to existing public health practice by enabling researchers, funders, advocates, and evaluators to visualize, reframe, discuss, and communicate with policymakers and the public to resolve important public health issues.

    This description and exploration of the early years of Servicio Nacional de Salud, founded in 1952, analyzes the agency's progress and challenges, as well as the role of the Programa de Salud Materno-Infantil. The latter program lent continuity to a variety of sanitary protection policies for mothers and children dating to the 1920s, while also improving and expanding on existing policies and devising new ones within the framework of social medicine. The program recorded successes but also encountered limitations, which derived not only from agency-specific problems but also from the social and economic ills afflicting the country as a whole.

    In 2002, the National Heart, Lung, and Blood Institute partnered with the Health Resources and Services Administration's (HRSA's) Bureau of Primary Health Care and Office of Rural Health Policy to address cardiovascular health in the US-Mexico border region. From 2003 through 2005, the 2 agencies agreed to conduct an intervention program using Salud para su Corazón with promotores de salud (community health workers) in high-risk Hispanic communities served by community health centers (CHCs) in the border region to reduce risk factors and improve health behaviors. Promotores de salud from each CHC delivered lessons from the curriculum Your Heart, Your Life. Four centers implemented a 1-group pretest-posttest study design. Educational sessions were delivered for 2 to 3 months. To test Salud para su Corazón-HRSA health objectives, the CHCs conducted the program and assessed behavioral and clinical outcomes at baseline, 3 months, 6 months, and 12 months after the intervention. A 2-sample paired t test and analyses of variance were used to evaluate differences from baseline to postintervention. Changes in heart-healthy behaviors were observed, as they have been in previous Salud para su Corazón studies, lending credibility to the effectiveness of a promotores de salud program in a clinical setting. Positive changes were also observed in low-density lipoprotein cholesterol level, triglyceride level, waist circumference, diastolic blood pressure, weight, and glycated hemoglobin (HbA1c). Results suggest that integrating promotores de salud into clinical practices is a promising strategy for culturally competent and effective service delivery. Promotores de salud build coalitions and partnerships in the community. The Salud para su Corazón-HRSA initiative was successful in helping to develop an infrastructure to support a promotores de salud workforce in the US-Mexico border region.

    Objetivos. Examiné los efectos combinados del acceso a la atención primaria mediante el Programa de Salud Familiar (PSF) y las transferencias condicionadas de dinero en efectivo del Programa Bolsa Familia (PBF) sobre la mortalidad infantil posneonatal (MIPN) en Brasil. Métodos. Empleé un análisis ecológico longitudinal usando datos en panel de 4 583 municipios brasileños de 1998 al 2010, con 54 253 observaciones en total. Estimé modelos de regresión de efectos fijos por mínimos cuadrados ordinarios, con la tasa de MIPN como la variable dependiente y el PSF, el PBF y sus interacciones como las principales variables independientes de interés. Resultados. La asociación de una mayor cobertura del PSF con una menor tasa de MIPN se volvió más fuerte conforme aumentaba la cobertura del PBF. En los promedios de todas las demás variables, cuando la cobertura de PBF era 25%, la MIPN predicha fue 5,24 (intervalo de confianza [IC] de 95% = 4,95, 5,53) para una cobertura del PSF de 0%, y de 3,54 (IC de 95% = 2,77, 4,31) para una cobertura del PSF de 100%. Cuando la cobertura del PBF era de 60%, la MIPN predicha fue 4,65 (IC de 95% = 4,36, 4,94) para una cobertura del PSF de 0%, y de 1,38 (IC de 95% = 0,88, 1,89) para una cobertura del PSF de 100%. Conclusiones. El efecto del PSF depende de la ampliación del PBF. Para las poblaciones empobrecidas y subatendidas, la combinación de intervenciones tanto del lado de la oferta como del lado de la demanda podría ser necesaria para mejorar los resultados en salud.

    Background Although rates of neural tube defects (NTDs) have declined in the United States since fortification, disparities still exist with Hispanic women having the highest risk of giving birth to a baby with a NTD. The Promotora de Salud model has been shown to be an effective tool for reaching Hispanics for a variety of health topics; however, literature on its effectiveness in folic acid interventions is limited. Methods An intervention using the Promotora de Salud model was implemented in four U.S. counties with large populations of Hispanic women. The study comprised: 1) a written pre-test survey to establish baseline levels of folic acid awareness, knowledge, and consumption; 2) a small group education intervention along with a 90-day supply of multivitamins; and 3) a post-intervention (post-test) assessment conducted four months following the intervention. Results Statistically significant differences in pre- and post-tests were observed for general awareness about folic acid and vitamins, and specific knowledge about the benefits of folic acid. Statistically significant changes were also seen in vitamin consumption and multivitamin consumption. Folic acid supplement consumption increased dramatically by the end of the study. Conclusions The Promotora de Salud model relies on interpersonal connections forged between promotoras and the communities they serve to help drive positive health behaviors. The findings underscore the positive impact that these interpersonal connections can have on increasing awareness, knowledge, and consumption of folic acid. Utilizing the Promotora de Salud model to reach targeted populations might help organizations successfully implement their programs in a culturally appropriate manner. PMID:28067585

    Weight gain in young women suggests that childbearing may be an important contributor to the development of obesity in women. Depressive symptoms can interfere with resumption of normal activity levels following childbirth or with the initiation of or adherence to physical activity programs essential for losing pregnancy weight. Depression symptoms may function directly to promote weight gain through a physiologic mechanism. Obesity and its related insulin resistance may contribute to depressed mood physiologically. Although physical activity has well-established beneficial effects on weight management and depression, women tend to under participate in physical activity during childbearing years. Further, the mechanisms underpinning the interplay of overweight, obesity, physical activity, depression, and inflammatory processes are not clearly explained. This report describes the theoretical rationale, design considerations, and cultural relevance for "Madres para la Salud" [Mothers for Health]. Madres para la Salud is a 12 month prospective, randomized controlled trial exploring the effectiveness of a culturally specific intervention using "bouts" of physical activity to effect changes in body fat, systemic and fat tissue inflammation, and postpartum depression symptoms in sedentary postpartum Latinas. The significance and innovation of Madres para la Salud includes use of a theory-driven approach to intervention, specification and cultural relevance of a social support intervention, use of a Promotora model to incorporate cultural approaches, use of objective measures of physical activity in post partum Latinas women, and the examination of biomarkers indicative of cardiovascular risk related to physical activity behaviors in postpartum Latinas.

    RESUMEN El presente artículo es una revisión sobre la contaminación del agua, el aire y el efecto del cambio climático en la salud de la población peruana. Uno de los principales contaminantes del aire es el material particulado menor de 2,5 μ (PM 2,5), en la ciudad de Lima, anualmente 2300 muertes prematuras son atribuibles a este contaminante. Otro problema es la contaminación del aire domiciliario por el uso de cocinas con combustible de biomasa, donde la exposición excesiva a PM 2,5 dentro de las casas es responsable de aproximadamente 3000 muertes prematuras anuales entre adultos, con otro número desconocido de muertes entre niños debido a infecciones respiratorias. La contaminación del agua tiene como principales causas los desagües vertidos directamente a los ríos, minerales (arsénico) de varias fuentes, y fallas de las plantas de tratamiento. En el Perú, el cambio climático puede impactar en la frecuencia y severidad del fenómeno de El Niño oscilación del sur (ENSO) que se ha asociado con un incremento en los casos de enfermedades como cólera, malaria y dengue. El cambio climático incrementa la temperatura y puede extender las áreas afectadas por enfermedades transmitidas por vectores, además de tener efecto en la disponibilidad del agua y en la contaminación del aire. En conclusión, el Perú, pasa por una transición de factores de riesgo ambientales, donde coexisten riesgos tradicionales y modernos, y persisten los problemas infecciosos y crónicos, algunos de los cuales se asocian con problemas de contaminación de agua y de aire.

    Con A hepatitis is regarded as a T cell-mediated model of acute liver injury. Mincle is a C-type lectin receptor that is critical in the immune response to mycobacteria and fungi but does not have a well-defined role in preclinical models of non-pathogen-mediated inflammation. Because Mincle can ligate the cell death ligand SAP130, we postulated that Mincle signaling drives intrahepatic inflammation and liver injury in Con A hepatitis. Acute liver injury was assessed in the murine Con A hepatitis model using C57BL/6, Mincle(-/-), and Dectin-1(-/-) mice. The role of C/EBPβ and hypoxia-inducible factor-1α (HIF-1α) signaling was assessed using selective inhibitors. We found that Mincle was highly expressed in hepatic innate inflammatory cells and endothelial cells in both mice and humans. Furthermore, sterile Mincle ligands and Mincle signaling intermediates were increased in the murine liver in Con A hepatitis. Most significantly, Mincle deletion or blockade protected against Con A hepatitis, whereas Mincle ligation exacerbated disease. Bone marrow chimeric and adoptive transfer experiments suggested that Mincle signaling in infiltrating myeloid cells dictates disease phenotype. Conversely, signaling via other C-type lectin receptors did not alter disease course. Mechanistically, we found that Mincle blockade decreased the NF-κβ-related signaling intermediates C/EBPβ and HIF-1α, both of which are necessary in macrophage-mediated inflammatory responses. Accordingly, Mincle deletion lowered production of nitrites in Con A hepatitis and inhibition of both C/EBPβ and HIF-1α reduced the severity of liver disease. Our work implicates a novel innate immune driver of Con A hepatitis and, more broadly, suggests a potential role for Mincle in diseases governed by sterile inflammation.

Conversely, signaling via other CLRs did not alter disease course. Mechanistically, we found that Mincle blockade decreased the NF-κβ related signaling intermediates, C/EBPβ and HIF-1α, both of which are necessary in macrophage-mediated inflammatory responses. Accordingly, Mincle deletion lowered production of nitrites in Con-A hepatitis and inhibition of both C/EBPβ and HIF1-α reduced the severity of liver disease. Our work implicates a novel innate immune driver of Con-A hepatitis and, more broadly, suggests a potential role for Mincle in diseases governed by sterile inflammation. PMID:27559045

    Salud Para Su Carozón is a culturally sensitive, community-based program to increase heart healthy knowledge and behaviors among Latinos. Promotoras were trained using a 10-session manual to teach participants from 7 communities about heart disease risk factors and skills to achieve heart healthy behaviors. In 435 participants with pre-to-post self-reported data, there were increases in physical activity outside of work (57%-78%), heart health knowledge (49%-76%), and confidence in preparing heart healthy meals (66%-81%) (all Ps < .001). Results suggest that promotoras can provide effective health education to improve heart health risk behaviors in select Latino communities.

    Objetivo: la presentación de un caso de una paciente con un ependimoma sacro con extensa infiltración y destrucción ósea local. Descripción del caso: una mujer de 53 años acudió a la consulta por dolor lumbosacro y alteraciones sensitivas perineales y esfinterianas. La imágenes por Resonancia Magnética (IRM) y la Tomografía Axial Computada (TAC) mostraron una lesión expansiva gigante a nivel S2-S4 con extensa osteólisis e invasión de tejidos adyacentes. Se realizó una exéresis tumoral completa con mejoría del estatus funcional. La anatomía patológica informó ependimoma mixopapilar. Discusión: la extensión de la resección quirúrgica es el mejor predictor de buen pronóstico. El tratamiento radiante se reserva como opción adyuvante para las resecciones incompletas y recidiva tumoral. La quimioterapia sólo debería utilizarse en casos en que la cirugía y la radioterapia estén contraindicadas. Conclusión: Los ependimomas mixopapilares sacros con destrucción ósea y presentación intra y extradural son muy infrecuentes y deben ser tenidos en cuenta entre los diagnósticos diferenciales preoperatorios. Su resección total, siempre que sea posible, es la mejor alternativa terapéutica. PMID:25165615

    Community health workers (promotores de salud) have the ability to empower communities to mitigate negative health outcomes. Current training efforts in environmental topics are lacking. This project addressed this gap by developing 4 transferable training modules on environmental health. By applying a series of surveys, interviews, and trainings, we evaluated their relevance. Partners provided favorable feedback for 3 of the 4 modules. It was also learned that the development method could be improved by engaging technically trained promotores de salud in the role of co-creators. This project has implications for environmental justice communities as it can lessen information disparities.

    While U.S. health care reform will most likely reduce the overall number of uninsured Mexican-Americans, it does not address challenges related to health care coverage for undocumented Mexican immigrants, who will remain uninsured under the measures of the reform; documented low-income Mexican immigrants who have not met the five-year waiting period required for Medicaid benefits; or the growing number of retired U.S. citizens living in Mexico, who lack easy access to Medicare-supported services. This article reviews two promising binational initiatives that could help address these challenges—Salud Migrante and Medicare in Mexico; discusses their prospective applications within the context of U.S. health care reform; and identifies potential challenges to their implementation (legal, political, and regulatory), as well as the possible benefits, including coverage of uninsured Mexican immigrants, and their integration into the U.S. health care system (through Salud Migrante), and access to lower-cost Medicare-supported health care for U.S. retirees in Mexico (Medicare in Mexico).

    The prevalence of overweight and obesity in children has risen nationally in recent decades, and is exceptionally high in low-income communities of color such as South Los Angeles CA. Independently owned restaurants participating in the Salud Tiene Sabor program at ethnic foods marketplace Mercado La Paloma in South Los Angeles are responding to the childhood obesity crisis by posting calories for menu items and providing nutrition information to patrons. To evaluate whether menu labeling and nutrition information at point of purchase have an influence on availability of healthy food options, patron awareness of calorie information, and restaurant owners' support of the program. A case-study design using mixed methods included restaurant owner and stakeholder interviews, patron surveys, and environmental assessments. Data were collected using originally designed tools, and analyzed in 2009-2011. Healthy eating options were available at the Mercado La Paloma; restaurant owners and the larger community supported the Salud Tiene Sabor program; 33% of patrons reported calorie information-influenced purchase decisions. Owners of independent restaurants have an important role in improving access to healthy foods in low-income, Latino communities. Copyright © 2013 American Journal of Preventive Medicine.

    Even though the technique of mammalian SCNT is just over a decade old it has already resulted in numerous significant advances. Despite the recent advances in the reprogramming field, SCNT remains the bench-mark for the generation of both genetically unmodified autologous pluripotent stem cells for transplantation and for the production of cloned animals. In this review we will discuss the pros and cons of SCNT, drawing comparisons with other reprogramming methods.

    Meta Salud is a community health worker-facilitated intervention in Hermosillo, Sonora, Mexico, and was adapted from Pasos Adelante, a similar evidence-based intervention developed for a Latino population in the United States-Mexico border region. The objective of this study was to examine outcomes for Meta Salud and compare them with outcomes for Pasos Adelante. This pretest-posttest study took place during 13 weeks among low-income residents of an urban area. The program provided information on topics such as heart health, physical activity, nutrition, diabetes, healthy weight, community health, and emotional well-being; included individual and group activities aimed at motivating behavior change; and encouraged participants to engage in brisk physical activity. We found significant decreases from baseline to conclusion in body mass index, waist circumference, hip circumference, weight, triglycerides, and low-density lipoprotein (LDL) cholesterol. From baseline to 3-month follow-up, we found significant decreases in body mass index, waist circumference, weight, LDL cholesterol, and glucose, and an increase in high-density lipoprotein cholesterol. Outcomes for Meta Salud were similar to those found for Pasos Adelante. The physiological improvements found among participants in Meta Salud and comparable changes among participants in Pasos Adelante suggest a scalable and effective behavioral intervention for regions of the United States and Mexico that share a common boundary or have similar cultural and linguistic characteristics.

    Introducción: la diabetes mellitus es una de las enfermedades crónicas de mayor prevalencia e impacto económico a nivel mundial. La diabetes produce un impacto sobre la calidad de vida relacionada con la salud de las personas que la padecen. El cuestionario SF-6D permite evaluar la calidad de vida relacionada con la salud. Es uno de los cuestionarios más usados a nivel mundial, ya que permite conocer las preferencias sociales de los distintos estados de salud. Sin embargo, según nuestro conocimiento no se dispone de los valores normativos de este cuestionario en la población diabética chilena. Objetivo: reportar los datos normativos del cuestionario SF-6D en la población diabética chilena. Métodos: los datos fueron extraídos de la Encuesta Nacional de Salud (ENS 2009-2010) de Chile. En este estudio se incluyen 424 personas que presentan diabetes (143 hombres y 281 mujeres). Los datos se han presentado segregados por sexo y grupo de edad, así como por región, estado civil, hábito tabáquico, nivel de ingresos y estudios. Resultados: el índice de utilidad del SF-6D en mujeres chilenas con diabetes fue de 0,65 (± 0,15), mientras que en hombres fue 0,70 (± 0,15). Menos del 5% de la población declara una utilidad con valor 1. El índice de utilidad del SF-6D en pacientes con diabetes disminuye con la edad, en las situaciones de bajos ingresos y con niveles de educación bajos. Conclusiones: este estudio presenta los valores normativos chilenos del SF-6D derivado del SF-12 en pacientes con diabetes.

    During the past 10 years, the Instituto Nacional de Salud Pública (National Institute of Public Health) in Mexico has meticulously revised its educational model. This analysis resulted in the transformation of its educational model by tracing a new path in the pedagogical structure and faculty development to meet current challenges and students' needs. The first stage dealt with the national and international accreditation standards that came with the 21st century. The second stage responded to evidence of cognitive research showing that students are better prepared when they are engaged, active, and responsible for their own learning. This transformation was grounded on the use of information and communication technologies and on a competency-based educational approach that has led the expansion and innovation of educational practice.

    While individuals of Mexican origin are the largest immigrant group living in the U.S., this population is also the highest uninsured. Health disparities related to access to health care, among other social determinants, continue to be a challenge for this population. The government of Mexico, in an effort to address these disparities and improve the quality of life of citizens living abroad, has partnered with governmental and non-governmental health-care organizations in the U.S. by developing and implementing an initiative known as Ventanillas de Salud-Health Windows-(VDS). The VDS is located throughout the Mexican Consular network and aim to increase access to health care and health literacy, provide health screenings, and promote healthy lifestyle choices among low-income and immigrant Mexican populations in the U.S.

    Background Weight gain in young women suggests that childbearing may be an important contributor to the development of obesity in women. Depressive symptoms can interfere with resumption of normal activity levels following childbirth or with the initiation of or adherence to physical activity programs essential for losing pregnancy weight. Depression symptoms may function directly to promote weight gain through a physiologic mechanism. Obesity and its related insulin resistance may contribute to depressed mood physiologically. Although physical activity has well-established beneficial effects on weight management and depression, women tend to under participate in physical activity during childbearing years. Further, the mechanisms underpinning the interplay of overweight, obesity, physical activity, depression, and inflammatory processes are not clearly explained. Objectives This report describes the theoretical rationale, design considerations, and cultural relevance for “Madres para la Salud” [Mothers for Health]. Design and Methods Madres para la Salud is a 12 month prospective, randomized controlled trial exploring the effectiveness of a culturally specific intervention using “bouts” of physical activity to effect changes in body fat, systemic and fat tissue inflammation, and postpartum depression symptoms in sedentary postpartum Latinas. Summary The significance and innovation of Madres para la Salud includes use of a theory-driven approach to intervention, specification and cultural relevance of a social support intervention, use of a Promotora model to incorporate cultural approaches, use of objective measures of physical activity in post partum Latinas women, and the examination of biomarkers indicative of cardiovascular risk related to physical activity behaviors in postpartum Latinas.

  10. Energy Star program benefits Con Edison

    SciTech Connect

    1995-05-01

    Impressed with savings in energy costs achieved after upgrading the lighting and air conditioning systems at its Manhattan headquarters, Home Box Office (HBO) wanted to do more, James Flock, vice president for computer and office systems, contacted Con Edison Co. of New York in March 1991 to determine what the company could do to save money by reducing energy consumed by personal computers. Arthur Kressner, Con Edison Research and Development manager contacted industry organizations and manufacturers for advice, but was told only to shut off computers at night and on weekends. Kressner arranged a series of meetings with IBM and the Electric Power Research Institute (EPRI) to discuss the issue, then approached the U.S. Environmental Protection Agency (EPA), which was designing a program to promote the introduction and use of energy-efficient office equipment. In 1992, the EPA announced the Energy Star program for PCs, enabling manufacturers to display the Energy Star logo on machines meeting program criteria, including the ability to enter a sleep mode in which neither the computer nor monitor consume more than 30 W or electricity. Industry experts estimate national energy consumption by office equipment could double by the year 2000, but Energy Star equipment is expected to improve efficiency and help maintain electric loads.

    Resumen Introducción el Programa Nacional de Sida garantiza el acceso universal a los antirretrovirales, aun así las personas que reciben medicamentos a través del sistema público no logran obtener una carga viral indetectable en la misma proporción que los pacientes del sistema privado. Este estudio cualitativo tiene como objeto identificar los factores asociados a la adherencia y retención en la cascada de atención de VIH de los sistemas de salud público y privado de Buenos Aires, según las percepciones de pacientes y del personal de salud. Métodos se registraron datos cualitativos de 12 entrevistas semi-estructuradas a informantes clave y 4 grupos focales de pacientes y personal de salud tanto del sistema público como privado. Se codificaron y analizaron temas predeterminados sobre adherencia, utilizando el software QRS Nvivo9® de análisis de datos cualitativos. Resultados pacientes y personal de salud de ambos sistemas coinciden en la importancia del estigma asociado al VIH, la relación médicopaciente, la comunicación entre ambos y la división de responsabilidades en relación al tratamiento como aspectos fundamentales para la adherencia y retención en la cascada de atención. Se observan diferencias entre los sistemas en la forma en que algunos de estos aspectos actúan. Las barreras estructurales se presentan como principales obstáculos del sistema público. Discusión se resalta la necesidad de intervenciones focalizadas en la díada médico-paciente que considere las particularidades de cada sistema de atención para facilitar el compromiso del paciente en la adherencia.

    2012-01-01

    Background: Cervical disc arthroplasty has emerged as a promising potential alternative to anterior cervical discectomy and fusion (ACDF) in appropriately selected patients. Despite a history of excellent outcomes after ACDF, the question as to whether a fusion leads to adjacent segment degeneration remains unanswered. Numerous US investigational device exemption trials comparing cervical arthroplasty to fusion have been conducted to answer this question. Methods: This study reviews the current research regarding cervical athroplasty, and emphasizes both the pros and cons of arthroplasty as compared with ACDF. Results: Early clinical outcomes show that cervical arthroplasty is as effective as the standard ACDF. However, this new technology is also associated with an expanding list of novel complications. Conclusion: Although there is no definitive evidence that cervical disc replacement reduces the incidence of adjacent segment degeneration, it does show other advantages; for example, faster return to work, and reduced need for postoperative bracing.

    Childhood obesity rates in minority populations continue to rise despite leveling national trends. Although interventions that address social and environmental factors exist, processes that create demand for policy and environmental change within communities have not been identified. We developed a pilot program in South Omaha, a Nebraska Latino community, based on the community readiness model (CRM), called SaludableOmaha. We used CRM to explore the potential of youth advocacy to shift individual and community norms regarding obesity prevention in South Omaha and to advocate for health-promoting community environments. We used CRM to assess supply and demand for health programs, engage the community, determine the community's baseline readiness to address childhood obesity, and guide youth advocacy program development. We conducted our project in 2 phases. In the first, we trained a cohort of youth. In the second, the youth cohort created and launched a Latino health movement, branded as SaludableOmaha. A third phase, which is currently under way, is directed at institutionalizing youth advocacy in communities. At baseline, the community studied was at a low stage of readiness for change. Our program generated infrastructure and materials to support the growth and institutionalization of youth advocacy as a means of increasing community readiness for addressing obesity prevention. CRM is an important tool for addressing issues such as childhood obesity in underserved communities because it provides a framework for matching interventions to the community. Community partnerships such as SaludableOmaha can aid the adoption of obesity prevention programs.

    Background A community’s readiness for change is a precursor to the effective application of evidence-based practices for health promotion. Research is lacking regarding potential strategies to improve readiness to address obesity-related health issues in underserved communities. Community Context This case study describes SaludABLEOmaha, an initiative to increase readiness of residents in a Midwestern Latino community to address obesity and adopt healthy lifestyles. Methods SaludABLEOmaha emphasized 2 core approaches, youth activism and collaboration among public and private institutions, which we applied to planning and implementing tactics in support of 3 interconnected strategies: 1) social marketing and social media, 2) service learning in schools (ie, curricula that integrate hands-on community service with instruction and reflection), and 3) community and business engagement. Following the Community Readiness Model protocol (http://triethniccenter.colostate.edu/communityReadiness.htm), structured interviews were conducted with community leaders and analyzed before and 2.5 years after launch of the program. Outcome The community increased in readiness from stage 3 of the Community Readiness Model, “vague awareness,” at baseline to stage 5, “preparation,” at follow-up. Interpretation SaludABLEOmaha improved community readiness (eg, community knowledge, community climate), which probably contributed to the observed increase in readiness to address obesity through healthy lifestyle. Community mobilization approaches such as youth activism integrated with social marketing and social media tactics can improve community responsiveness to obesity prevention and diminish health disparities.

    To evaluate the coverage of Mexican journals and manuscripts of biomedical research in a Mexican data base (Bibliomex Salud) during its 10 years of existence (1985-1994). All the manuscripts published by a single Mexican journal Revista de Investigación Clínica (RIC) were searched for in Bibliomex: the absence of a RIC manuscript in Bibliomex was considered a failure. Also, the number and identity of the Mexican journals included in Bibliomex was also noted. From a total of 744 manuscripts 99 were excluded (22 non-Mexican, 25 nonindexable, and 52 initially not indexed by Bibliomex). The remainder (645) were classified according to starting year of indexing: originals since the first year; letters to the editor since 1990; and editorials and authors' replies since 1993. Bibliomex started out with 21 Mexican journals and now has more than 50 (12 indexed during the 10 years, 27 for the last 5-9 years, and 16 for the last 1-4 years). Regarding manuscripts, Bibliomex had an 8% failure rate in originals (46/597) and letters (3/36), and 25% in editorials and authors' replies (3/12). a) The coverage of Bibliomex has improved in its second half of life in the number of both journals and manuscripts indexed; b) the retrieval of information could be improved by two changes in the procedures of Bibliomex; c) Bibliomex seems to be a database which could be used to analyze Mexican research production at several levels (institutional, regional, and national).

    Breast cancer is the most commonly diagnosed cancer and the most common cause of cancer mortality among Latino women. Several behavioral factors such as early detection and dietary practices could help decrease morbidity and mortality associated with breast cancer in this population. Unfortunately, there are few data regarding the efficacy of health-related interventions for young Latino women. Mujeres Felices por ser Saludables is a randomized intervention project designed to assess breast cancer risk reduction behavior among Latino women ages 20-40 years. The primary objectives of the project were to determine whether an 8-month integrated dietary/breast health intervention could lead to a greater reduction in dietary fat, increase in dietary fiber, increase in the frequency and proficiency of breast self examination (BSE), and reduction in anxiety related to BSE compared to controls. Herein we describe the overall design of the project and present baseline characteristics of the 256 randomized women. Our results suggest that the average daily intake of dietary fat (percentage of total energy) was slightly below 30% (percentage of total energy) among the women randomized. While over half of these women reported that they practice BSE, and few reported anxiety related to BSE, less than 27% of women were proficient in the recommended BSE technique. There are few data on the dietary and breast health behaviors of young low-acculturated Latino women. This study documents the feasibility of recruiting, randomizing, and obtaining both baseline dietary and breast health data on this unique and underserved population.

    Community health advisors have effectively promoted breast and cervical cancer prevention and screening among low-income Latina women. Specific elements of such programs, such as enhanced social support, may explain successes. Promotion of colorectal cancer screening has been less studied. Promotoras de Salud (i.e., Latina health advisors) implemented a 12-week program among women recruited from community-based organizations. The program educated 366 Latinas in breast, cervical and colorectal cancer prevention and screening and emphasized social support among class members. Pre- and post-intervention assessments demonstrated significant increases for fruit and vegetable consumption (3.05 to 3.60 servings/day), and physical activity (65.15 to 122.40 minutes/week). Of women previously non-compliant, 39 percent, 31 percent and 4 percent received Pap tests, mammography, and fecal occult blood test (FOBT), respectively. A culturally aligned education program using community health advisors and emphasizing social support among participants may improve prevention and selected screening behaviors, but more intensive interventions may be required for colorectal cancer screening compliance.

    To prepare a set of quality and safety indicators for Hospitals of the «Agencia Valenciana de Salud». The qualitative technique Metaplan® was applied in order to gather proposals on sustainability and nursing. The catalogue of the «Spanish Society of Quality in Healthcare» was adopted as a starting point for clinical indicators. Using the Delphi technique, 207 professionals were invited to participate in the selecting the most reliable and feasible indicators. Lastly, the resulting proposal was validated with the managers of 12 hospitals, taking into account the variability, objectivity, feasibility, reliability and sensitivity, of the indicators. Participation rates varied between 66.67% and 80.71%. Of the 159 initial indicators, 68 were prioritized and selected (21 economic or management indicators, 22 nursing indicators, and 25 clinical or hospital indicators). Three of them were common to all three categories and two did not match the specified criteria during the validation phase, thus obtaining a final catalogue of 63 indicators. A set of quality and safety indicators for Hospitals was prepared. They are currently being monitored using the hospital information systems. Copyright © 2013 SECA. Published by Elsevier Espana.

  3. Pros and cons of phage therapy

    PubMed Central

    Loc-Carrillo, Catherine

    2011-01-01

    Many publications list advantages and disadvantages associated with phage therapy, which is the use of bacterial viruses to combat populations of nuisance or pathogenic bacteria. The goal of this commentary is to discuss many of those issues in a single location. In terms of “Pros,” for example, phages can be bactericidal, can increase in number over the course of treatment, tend to only minimally disrupt normal flora, are equally effective against antibiotic-sensitive and antibiotic-resistant bacteria, often are easily discovered, seem to be capable of disrupting bacterial biofilms, and can have low inherent toxicities. In addition to these assets, we consider aspects of phage therapy that can contribute to its safety, economics, or convenience, but in ways that are perhaps less essential to the phage potential to combat bacteria. For example, autonomous phage transfer between animals during veterinary application could provide convenience or economic advantages by decreasing the need for repeated phage application, but is not necessarily crucial to therapeutic success. We also consider possible disadvantages to phage use as antibacterial agents. These “Cons,” however, tend to be relatively minor. PMID:22334867

Evaluar el coste-efectividad del midazolam bucal respecto al diacepam rectal para los niños con un diagnostico de epilepsia que presentan crisis convulsivas prolongadas en la comunidad en España. Materiales y metodos. Modelo coste-efectividad desde la perspectiva del Sistema Nacional de Salud (SNS) español, con resultados presentados en terminos de costes y años de vida ajustados por calidad. Los datos se obtuvieron de varias fuentes, incluidas las estimaciones de efectividad clinica de un ensayo clinico, de un panel Delphi en España y de una encuesta nacional a padres de niños con epilepsia para determinar las practicas actuales. Resultados. El tratamiento con midazolam bucal produce un ahorro de costes en comparacion con el diacepam rectal. El ahorro para el SNS español es de 5.484 euros por paciente al año. El tratamiento con midazolam bucal ofrece una mejora en la calidad de vida relacionada con la salud. Esto, unido al ahorro de costes, hace que el midazolam bucal sea dominante frente al diacepam rectal en todos los escenarios examinados. Conclusion. Los resultados del modelo muestran que el midazolam bucal es mas coste-efectivo que el diacepam rectal debido a una reduccion en la necesidad de llamadas a la ambulancia y estancias en el hospital, asi como a una mejora en la calidad de vida relacionada con la salud.

    2003-04-01

    The modest amount of research that exists on the ability, or lack of ability, of mantle precession to power a geodynamo developed mostly during the last half of the 1900s. Papers by Roberts and Stewartson (1965) and by Busse (1968) studied precession generally without a pro/con conclusion. Malkus in the late 1960s attempted to advance a positive role for precession through experiments and analysis. His experiments have survived criticism, but his analyses were discounted, especially by Rochester, Jacobs, Smylie, and Chong (1975) and by Loper (1975). Rochester, et al. critiqued existing analyses of precession, including those of Malkus, but did not reach a strong position either pro or con a precessional geodynamo. Loper argued emphatically that precession was not capable of powering the geodynamo. Explicit analyses that either critique or support Loper’s arguments have yet to appear in the literature. During the 1970s, Vanyo and associates studied energy dissipation during precession of satellite liquid fuels and its effect on satellite attitude stability. Engineers and scientists in every country that has launched satellites completed similar research. Some is published in the aerospace literature, more is available in company and government reports. Beginning in 1981, Vanyo and associates applied this knowledge to the very similar problem of energy dissipation and flow patterns in precessing mechanical models scaled geometrically and dynamically to the Earth’s liquid core. Energy experiments indicate massive amounts of mechanical energy are dissipated at the CMB, and flow experiments show complex motions within the boundary layer and axial flows with helicity throughout the interior. Analysis of Earth core precession also advanced, especially in several papers by Kerswell and by Tilgner in the late 1990s. Detail numerical models have yet to appear. Although progress in understanding the role of precession in Earth core motions has advanced, there remains a

    Latinas/os with traumatic brain injuries (TBIs) and their caregivers experience worse outcomes than others. The study aimed to assess the acceptability and promise of Trabajadora de Salud on the functional abilities, hospital readmission, rehabilitation, employment, depression, somatic symptoms, and caregiver burden among Latinas/os with TBIs and their caregivers. A pre-posttest experimental pilot study was conducted. A total of eight Latina/o adult patients (50% female) with mild or moderate TBI and six of their caregivers (66.7% female) were randomized to receive Trabajadora de Salud or a telephone only control group. Trabajadora de Salud, a three-month, in-home intervention administered by bilingual lay health workers, focused on: 1) providing empathy and validation of TBI symptoms, 2) addressing basic needs, 3) goal setting, and 4) improving communication with healthcare providers. Trabajadora de Salud was widely accepted by patients, caregivers, and health professionals. The functional, depression, and somatic symptoms of the patients as well as the somatic symptoms and caregiver burden of the caregivers improved more for participants in the intervention group than the control group. Trabajadora de Salud demonstrated promise in improving outcomes of Latinas/os with TBIs and their caregivers and should be further studied. Copyright © 2017 Elsevier Inc. All rights reserved.

We used multivariable logistic regression to measure the association between delivering a child in a health facility and select household and maternal characteristics, including education and measures of wealth. Health indicators varied greatly between geographic segments. Controlling for other demographic characteristics, women with at least secondary education were more likely to have an in-facility delivery compared to women who had not attended school (OR: 3.20, 95 % confidence interval [CI]: 2.56-3.99, respectively). Similarly, women from households with the highest expenditure were more likely to deliver in a health facility compared to those from the lowest expenditure households (OR 3.06, 95 % CI: 2.43-3.85). Household assets did not impact these associations. Moreover, we found that commonly-used definitions of poverty do not align with the disparities in health outcomes observed in these communities. Although poverty measured by expenditure or wealth is associated with health disparities or health outcomes, a composite indicator of health poverty based on coverage is more likely to focus attention on health problems and solutions. Our findings call for the public health community to define poverty by health coverage measures rather than income or wealth. Such a health-poverty metric is more likely to generate attention and mobilize targeted action by the health communities than our current definition of poverty.

    Healthy Weigh (El camino saludable) is an obesity prevention program for low-income, predominantly Hispanic and African American families in an urban community in Tarrant County, Texas. Healthy Weigh Phase 1 was a successful community-campus partnership that took place in summer (June-August) and fall (September-November) 2003. The program met stated objectives and extensively engaged students from several health disciplines in service learning. This article describes what we learned about the evaluation of the program by examining the phase 1 evaluation process. Family environments are important intervention settings for establishing life-long dietary practices. Available in English and Spanish, Healthy Weigh Phase 1 helped families that were at risk for overweight and obesity to adopt healthy eating, physical activity, and weight management patterns. Analysis of a program logic model and formative evaluation data identified evaluation questions that could have improved the phase 1 evaluation process. Questions were categorized according to Donabedian's structure-process-outcome framework, and potential benefits of each question were identified. The Centers for Disease Control and Prevention's Framework for Program Evaluation in Public Health standards were used to judge the overall quality of the phase 1 evaluation process. The phase 1 evaluation process successfully assessed the program's effects and generally met evaluation standards. Our critical examination also highlighted structure and process evaluation issues with potential for strengthening future interventions, community partnerships, and program outcomes. Lessons learned influenced the phase 2 grant activities. Most importantly, we learned that involvement of program participants as full partners in program design, evaluation, and implementation is essential. Our understanding and practice of program evaluation evolved as Healthy Weigh became a true community-based participatory research endeavor.

    This study examined the feasibility and efficacy of Salud es Vida-a promotora-led, Spanish language educational group session on cervical cancer screening (Pap tests)-self-efficacy (belief in ability to schedule and complete a Pap test), and knowledge among immigrant Hispanic/Latina women from farmworker backgrounds. These women are disproportionately burdened with cervical cancer, with mortality rates significantly higher than non-Hispanic whites. The two-arm, quasi-experimental study was conducted in four rural counties of Southeast Georgia in 2014-2015. Hispanic/Latina immigrant women aged 21-65 years and overdue for a Pap test were included as intervention (N = 38) and control (N = 52) group participants. The intervention was developed in partnership with a group of promotoras to create the toolkit of materials which includes a curriculum guide, a brochure, a flipchart, a short animated video, and in-class activities. Twelve (32 %) intervention group participants received the Pap test compared to 10 (19 %) control group participants (p = 0.178). The intervention group scored significantly higher on both cervical cancer knowledge recall and retention than the control group (p < 0.001). While there was no statistically significant difference in cervical cancer screening self-efficacy scores between the group participants, both groups scored higher at follow-up, adjusting for the baseline scores. The group intervention approach was associated with increased cervical cancer knowledge but not uptake of Pap test. More intensive interventions using patient navigation approaches or promotoras who actively follow participants or conducting one-on-one rather than group sessions may be needed to achieve improved screening outcomes with this population.

    To describe the physical activity (PA) and sedentary behaviors of postpartum Latinas who are overweight or obese before initiating Madres para la Salud, a social support-mediated walking intervention to promote postpartum weight loss. One hundred thirty-nine postpartum women (13.6 ± 7.7 wk since childbirth, age = 28.3 ± 5.6 yr, BMI = 29.7 ± 3.5 kg · m(-2); mean ± SD), recruited from organizations serving Latino residents in the Phoenix, Arizona, area completed the Stanford Brief Activity Survey and concurrently wore an accelerometer (ActiGraph) and a pedometer for 7 d and kept a PA record. Most were classified as inactive and lightly active on the Stanford Brief Activity Survey (51% inactive, 37% light, 11% moderate). Most time was spent in sedentary (512.0 ± 169.9 min · d(-1)) and light-intensity PA (242.4 ± 51.4 min · d(-1)) with less time in moderate-intensity lifestyle (78.3 ± 39.9 min · d(-1)), moderate-intensity walking (16.6 ± 14.4 min · d(-1)), and vigorous-intensity PA (0.34 ± 1.5 min · d(-1)). Pedometer steps per day were low (total = 4973 ± 2202 steps, aerobic = 412 ± 774 steps), with most participants rated as sedentary (61%) or low active (28.1%). Consistent with objective PA measures, PA records showed more time spent in light-intensity PA such as home care, cooking, child care and self-care tasks, occupation, religious events, and watching television. By and large, the postpartum Latinas enrolled spent most of their day in low-intensity activity levels with little time spent in health-enhancing PA levels/behaviors. This demographic should be the focus of PA interventions to increase PA to health-enhancing levels.

    "Prescribe Vida Saludable" (PVS) is an organisational innovation designed to optimise the promotion of multiple healthy habits in primary healthcare. It aims to estimate the cost effectiveness and cost-utility of prescribing physical activity in the pilot phase of the PVS programme, compared to the routine clinical practice of promoting physical activity in primary healthcare. An economic evaluation of the quasi-experimental pilot phase of PVS was carried out. In the four control centres, a systematic sample was selected of 194 patients who visited the centre in a single year and who did not comply with physical activity recommendations. In the four intervention centres, 122 patients who received their first physical activity prescription were consecutively enrolled. The costs were evaluated from the perspective of the PVS programme using bottom-up methodology. The effectiveness (proportion of patients who changed their physical activity) as well as the utility were evaluated at baseline and after 3 months. The incremental cost-utility ratio (ICUR) and the incremental cost-effectiveness ratio (ICER) were calculated and a sensitivity analysis was performed with bootstrapping and 1,000 replications. Information was obtained from 35% of control cases and 62% of intervention cases. The ICUR was €1,234.66/Quality Adjusted Life Years (QALY) and the ICER was €4.12. In 98.3% of the simulations, the ICUR was below the €30,000/QALY threshold. The prescription of physical activity was demonstrably within acceptable cost-utility limits in the pilot PVS phase, even from a conservative perspective. Copyright © 2017 SESPAS.

    Summary The Guatemalan NGO (Non-Governmental Organization) TulaSalud has implemented an m-health project in the Department of Alta Verapaz. This Department has 1.2 million inhabitants (78% living in rural areas and 89% from indigenous communities) and in 2012, had a maternal mortality rate of 273 for every 100,000 live births. This m-health initiative is based on the provision of a cell phone to community facilitators (CFs). The CFs are volunteers in rural communities who perform health prevention, promotion and care. Thanks to the cell phone, the CFs have become tele-CFs who able to carry out consultations when they have questions; send full epidemiological and clinical information related to the cases they attend to; receive continuous training; and perform activities for the prevention and promotion of community health through distance learning sessions in the Q’eqchí and/or Poqomchi’ languages. In this study, rural populations served by tele-CFs were selected as the intervention group while the control group was composed of the rural population served by CFs without Information and Communication Technology (ICT) tools. As well as the achievement of important process results (116,275 medical consultations, monitoring of 6,783 pregnant women, and coordination of 2,014 emergency transfers), the project has demonstrated a statistically significant decrease in maternal mortality (p < 0.05) and in child mortality (p = 0.054) in the intervention group compared with rates in the control group. As a result of the telemedicine initiative, the intervention areas, which were selected for their high maternal and infant mortality rates, currently show maternal and child mortality indicators that are not only lower than the indicators in the control area, but also lower than the provincial average (which includes urban areas).

    Background Childhood obesity rates in minority populations continue to rise despite leveling national trends. Although interventions that address social and environmental factors exist, processes that create demand for policy and environmental change within communities have not been identified. Community Context We developed a pilot program in South Omaha, a Nebraska Latino community, based on the community readiness model (CRM), called SaludableOmaha. We used CRM to explore the potential of youth advocacy to shift individual and community norms regarding obesity prevention in South Omaha and to advocate for health-promoting community environments. Methods We used CRM to assess supply and demand for health programs, engage the community, determine the community’s baseline readiness to address childhood obesity, and guide youth advocacy program development. We conducted our project in 2 phases. In the first, we trained a cohort of youth. In the second, the youth cohort created and launched a Latino health movement, branded as SaludableOmaha. A third phase, which is currently under way, is directed at institutionalizing youth advocacy in communities. Outcome At baseline, the community studied was at a low stage of readiness for change. Our program generated infrastructure and materials to support the growth and institutionalization of youth advocacy as a means of increasing community readiness for addressing obesity prevention. Interpretation CRM is an important tool for addressing issues such as childhood obesity in underserved communities because it provides a framework for matching interventions to the community. Community partnerships such as SaludableOmaha can aid the adoption of obesity prevention programs. PMID:23217590

    Introducción: la evaluación de la calidad de vida relacionada con la salud es fundamental en las terapias de reemplazo renal. Realizamos un estudio para evaluar la modificación en la calidad de vida a los 6 y 12 meses del trasplante renal y compararla con población sana y población general. Métodos: se realizó un estudio prospectivo en 278 receptores renales aplicando la encuesta SF-36 a los 0, 6 y 12 meses del trasplante. Los resultados fueron comparados con los obtenidos en población sana (donantes renales) y población general. Se empleó prueba t de student para realizar las comparaciones de medias. Una p < 0.05 fue considerada estadísticamente significativa.Resultados: la calidad de vida previa al trasplante fue inferior a la observada en población sana y población general (p < 0.001). A los 6 meses de trasplante se obtuvo mejoría significativa con respecto a la medición basal (p < 0.001) en los 8 dominios y las dos escalas compuestas, pero a los 12 meses no se observó un beneficio adicional. La calidad de vida de los receptores a los 12 meses de trasplante fue inferior solo en el concepto de salud general (p = 0.035) al compararse con la población sana. No obstante, fue superior a la población general en las escalas compuestas física y mental (p = 0.013 y p = 0.001 respectivamente).Conclusiones: la calidad de vida relacionada con la salud mejora significativamente a los 6 y 12 meses del trasplante renal, logrando equipararse con población sana y población general.

    Health has improved markedly in Mesoamerica, the region consisting of southern Mexico and Central America, over the past decade. Despite this progress, there remain substantial inequalities in health outcomes, access, and quality of medical care between and within countries. Poor, indigenous, and rural populations have considerably worse health indicators than national or regional averages. In an effort to address these health inequalities, the Salud Mesoamérica 2015 Initiative (SM2015), a results-based financing initiative, was established. For each of the eight participating countries, health targets were set to measure the progress of improvements in maternal and child health produced by the Initiative. To establish a baseline, we conducted censuses of 90,000 households, completed 20,225 household interviews, and surveyed 479 health facilities in the poorest areas of Mesoamerica. Pairing health facility and household surveys allows us to link barriers to care and health outcomes with health system infrastructure components and quality of health services. Indicators varied significantly within and between countries. Anemia was most prevalent in Panama and least prevalent in Honduras. Anemia varied by age, with the highest levels observed among children aged 0 to 11 months in all settings. Belize had the highest proportion of institutional deliveries (99%), while Guatemala had the lowest (24%). The proportion of women with four antenatal care visits with a skilled attendant was highest in El Salvador (90%) and the lowest in Guatemala (20%). Availability of contraceptives also varied. The availability of condoms ranged from 83% in Nicaragua to 97% in Honduras. Oral contraceptive pills and injectable contraceptives were available in just 75% of facilities in Panama. IUDs were observed in only 21.5% of facilities surveyed in El Salvador. These data provide a baseline of much-needed information for evidence-based action on health throughout Mesoamerica.

    The Sangre Por Salud (Blood for Health; SPS) Biobank was created for the purpose of expanding precision medicine research to include underrepresented Latino patients. It is the result of a unique collaboration between Mayo Clinic and Mountain Park Health Center, a federally qualified community health center in Phoenix, Arizona. This report describes the rationale, development, implementation, and characteristics of the SPS Biobank. Latino adults (ages 18-85 years) who were active patients within Mountain Park Health Center's internal medicine practice in Phoenix, Ariz., and had no history of diabetes were eligible. Participants provided a personal and family history of chronic disease, completed a sociodemographic, psychosocial, and behavioral questionnaire, underwent a comprehensive cardiometabolic risk assessment (anthropometrics, blood pressure and labs), and provided blood samples for banking. Laboratory results of cardiometabolic testing were returned to the participants and their providers through the electronic health record. During the first 2 years of recruitment into the SPS Biobank, 2,335 patients were approached and 1,432 (61.3%) consented to participate; 1,354 (94.5%) ultimately completed all requisite questionnaires and medical evaluations. The cohort is primarily Spanish-speaking (72.9%), female (73.3%), with a mean age of 41.3 ± 12.5 years. Most participants were born outside of the US (77.9%) and do not have health insurance (77.5%). The prevalence of overweight (35.5%) and obesity (45.0%) was high, as was previously unidentified prediabetes (55.9%), type 2 diabetes (7.4%), prehypertension (46.8%), and hypertension (16.2%). The majority of participants rated their health as good to excellent (72.1%) and, as a whole, described their overall quality of life as high (7.9/10). Collaborative efforts such as the SPS Biobank are critical for ensuring that underrepresented minority populations are included in precision medicine initiatives and biomedical

    Evaluations of Community Health Worker programs consistently document improvements in health, yet few articles clearly describe the roles of Community Health Workers (CHWs) from the CHWs' perspective. This article presents the CHWs' points of view regarding the various roles they played in a community-based participatory research (CBPR) project, Poder es Salud/Power for Health in Portland, Oregon, including their roles as community organizers and co-researchers. Authors draw from an analysis of transcript data from in-depth interviews conducted with CHWs to present a description of the strategies employed by the CHWs to build leadership skills and knowledge among community members. CHWs also discuss their own personal and professional development. The analysis of the interviews suggests that CHWs valued their multiple roles with Poder es Salud/Power for Health and their participation on the project's Steering Committee. Based on CHWs' descriptions of their work, this type of involvement appears to build the CHWs' leadership skills and sense of efficacy to create change in their communities. By serving as community organizers and participating as producers of research, rather than acting merely as a deliverer of the intervention activities, the CHWs were able to build skills that make them more successful as CHWs.

    To develop, and implement, a social marketing campaign to increase preconception health knowledge among second-generation Latinas in Oregon. Social marketing demonstration project. Latino communities in five Oregon counties. Target populations included young Latinas (18-29 years old) born in the United States of immigrant parents in five Oregon counties, and their family members. Intervention. A radionovela, Amor y Salud, was developed that featured a Latina and her fiancé preparing for marriage and family. Social media, Web sites, and culturally relevant print materials promoted the radio campaign. Process data, social media metrics, Google analytics, online and intercept surveys were collected. Basic frequencies and descriptive statistics were used. Twelve episodes were produced in English and Spanish and played on nine radio stations a total of 2098 times. The Facebook page was viewed 11,000 times, and radionovela episodes were played a total of 776 times. Amor y Salud used mixed media--radio, social media, print materials--to encourage Latinas to consider their preconception health. Anecdotally, we heard positive comments from community members and local media regarding the radionovela; however, evaluation challenges prevent us from saying conclusively that knowledge on this topic increased.

    In May 2007, the Instituto Carso de la Salud-now Instituto Carlos Slim de la Salud (ICSS)-was endowed with US$500 million to focus on priority health issues in Latin America, notably issues of 'globalisation and non-communicable diseases'. ICSS was soon criticised, however, on the grounds that its funding was derived from tobacco industry profits and that its founder Carlos Slim Hélu remained an active industry principal. Collaboration with ICSS was said to run counter to the WHO Framework Convention on Tobacco Control. The Institute's then Executive President Julio Frenk disputed these charges. This research employs an archive of tobacco industry documents triangulated with materials from commercial, media, regulatory and NGO sources to examine the financial relations between Slim and the tobacco industry. The paper analyses Slim's continuing service to the industry and role in ICSS. It demonstrates a prima facie conflict of interest between ICSS's health mission and its founder's involvement in cigarette manufacturing and marketing, reflected on ICSS's website as a resounding silence on issues of tobacco and health. It is concluded that the reliance of international health agencies upon the commercial sector requires more robust institutional policies to effectively regulate conflicts of interest.

    RESUMEN En este artículo se discute el papel de la familia y el vecindario en la salud de los ancianos méjico-americanos del estudio EPESE (Established Populations for Epidemiologic Studies of the Elderly) hispano. La paradoja epidemiológica consiste en que, a pesar de estar en desventaja socioeconómica, los ancianos hispanos tienen mortalidad relativamente menor que los ancianos de raza blanca. Esto es especialmente cierto cuando el anciano vive en los vecindarios donde hay un porcentaje alto de méjico-americanos. La familia también juega un papel importante en estos ancianos al disminuir el riesgo de institucionalización o de morbilidad. Asimismo, el estrés originado en problemas económicos o al depender económicamente de la familia, habiendo inmigrado en edades tardías, puede sobrepasar la capacidad de amortiguamiento del estrés y afectar la salud del anciano méjico-americano.

    Introducción: La individualidad anatómica es clave para reducir el trauma quirúrgico y obtener un mejor resultado. Actualmente, el avance en las neuroimágenes ha permitido objetivar esa individualidad anatómica, permitiendo planificar la intervención quirúrgica. Con este objetivo, presentamos nuestra experiencia con el software Osirix. Descripción de la técnica: Se presentan 3 casos ejemplificadores de 40 realizados. Caso 1: Paciente con meningioma de la convexidad parasagital izquierda en área premotora; Caso 2: Paciente con macroadenoma hipofisario, operada previamente por vía transeptoesfenoidal en otra institución con una resección parcial; Caso 3: Paciente con lesiones en pedúnculo cerebeloso medio bilateral. Se realizó la planificación prequirúrgica con el software OsiriX, fusionando y reconstruyendo en 3D las imágenes de TC e IRM, para analizar relaciones anatómicas, medir distancias, coordenadas y trayectorias, entre otras funciones. Discusión: El software OsiriX de acceso libre y gratuito permite al cirujano, mediante la fusión y reconstrucción en 3D de imágenes, analizar la anatomía individual del paciente y planificar de forma rápida, simple, segura y económica cirugías de alta complejidad. En el Caso 1 se pudo analizar las relaciones del tumor con las estructuras adyacentes para minimizar el abordaje. En el Caso 2 permitió comprender la anatomía post-operatoria previa del paciente, para determinar la trayectoria del abordaje transnasal endoscópico y la necesidad de ampliar su exposición, logrando la resección tumoral completa. En el Caso 3 permitió obtener las coordenadas estereotáxicas y trayectoria de una lesión sin representación tomográfica. Conclusión: En casos de no contar con costosos sistemas de neuronavegación o estereotáxia el software OsiriX es una alternativa a la hora de planificar la cirugía, con el objetivo de disminuir el trauma y la morbilidad operatoria.

    This article describes results of year-1 implementation of the Salud Para Su Corazón (Health For Your Heart)-National Council of la Raza (NCLR) promotora (lay health worker) program for promoting heart-healthy behaviors among Latinos. Findings of this community outreach initiative include data from promotora pledges and self-skill behaviors, cardiovascular disease risk factors of Latino families, family heart-health education delivery, and program costs associated with promotora time. Participation included 29 trained promotoras serving 188 families from three NCLR affiliates in Escondido, California; Chicago, Illinois; and Ojo Caliente, New Mexico. Using several evaluation tools, the results showed that the promotora approach worked based on evidence obtained from the following indicators: changes in promotora's pre-post knowledge and performance skills, progress toward their pledge goals following training, recruiting and teaching families, providing follow-up, and organizing or participating in community events. Strengths and limitations of the promotora model approach are also discussed.

    There is widespread recognition of the cultural and linguistic appropriateness of promotoras de salud (a Spanish term for community health workers) in health education and outreach among Hispanic communities. Yet there are significant gaps in the literature regarding the preparation, implementation and evaluation of promotoras’ engagement in research. To address this gap, we examine promotoras’ research-related training, roles, responsibilities, and contributions in a community-based participatory research project involving a multi-site randomized controlled trial of a physical activity intervention for Mexican-origin women in Texas and South Carolina. We identify both benefits and challenges associated with promotoras’ engagement as community researchers; examine variations and differences in promotora roles and responsibilities related to the research contexts, sites, settings, and individual characteristics; and discuss implications for research and practice.

    Biomedical journals are the most used and important venue to disseminate and interchange scientific information, and evaluation is an important component. A bibliometric study was conducted on the productivity, visibility and citation analysis of the Revista Peruana de Medicina Experimental y Salud Pública (RPMESP), from 2002 to 2009. During this period, the RPMESP published about 62 documents per year, 55.3% were research articles. The visibility of RPMESP, determined among three databases (SISBIB-UNMSM, SciELO-Peru, and REDALYC), was irregular, increasing on July 2006, with the highest access on October 2009 (117,618 hits). 43.0% of publications were cited. The calculated impact factor in ISI journals was 0.04 in 2009. In conclusion, the citation of RPMESP shows a slowly growing during the period 2002-2009. It is hoped that the RPMESP increase its visibility and impact after its inclusion in MEDLINE.

    Cardiovascular disease (CVD) is the leading cause of death for Latinos living in the United States. This population is generally unaware of important lifestyle or behavioral changes that can prevent CVD. The National Heart, Lung, and Blood Institute (NHLBI) designed and implemented Salud para su Corazón (Health for Your Heart), a culturally appropriate, community-based, theory-driven intervention model. NHLBI's goals were: (1) to design an intervention model appropriate to Latino populations; (2) to pilot test the model in a specific community with the objectives of increasing awareness about heart disease, raising knowledge about CVD prevention, and promoting heart-healthy lifestyles; and (3) to disseminate the model and the materials developed to other communities with similar needs. An agency-community partnership, under the leadership of the Community Alliance for Heart Health, guided all stages of the community intervention project. The multimedia bilingual community intervention included television telenovela format public service announcements (PSAs), radio programs, brochures, recipe booklets, charlas, a promotores training manual, and motivational videos. An evaluation survey assessed the impact of the intervention. A pre-post intervention survey was conducted with more than 300 participants, and results showed that the respondents were substantially more aware of risk factors for CVD, and had greatly increased their knowledge of ways to prevent heart disease. Dissemination efforts have resulted in numerous requests by health organizations, universities, and health maintenance organizations (HMOs) for educational materials and communication strategies produced by Salud para su Corazón. In addition, Univision, the largest Spanish-language broadcast television network, is airing the initiative's PSAs. Also, training seminars for promotores are being conducted in different regions of the United States, and several locations are planning to replicate this

    Given the large influence of social conditions on health, physicians may be more effective if they are trained to identify and address social factors that impact health. Despite increasing interest in teaching the social determinants of health in undergraduate medical education, few models exist. We present a 9-month pilot course on the social determinants of health for medical and other health professional students, which is based at Puentes de Salud, Philadelphia, PA, USA, a community health center serving a Latino immigrant population. This service-learning course, called the Health Scholars Program (HSP), was developed and implemented by volunteer medical and public health faculty in partnership with the community-based clinic. The HSP curriculum combines didactic instruction with service experiences at Puentes de Salud and opportunities for critical reflection. The HSP curriculum also includes a longitudinal project where students develop, implement, and evaluate an intervention to address a community-defined need. In our quantitative evaluation, students reported high levels of agreement with the HSP meeting stated course goals, including developing an understanding of the social determinants of health and working effectively with peers to implement community-based projects. Qualitative assessments revealed students' perception of learning more about this topic in the HSP than in their formal medical training and of developing a long-term desire to serve vulnerable communities as a result. Our experience with the HSP suggests that partnerships between academic medical centers and community-based organizations can create a feasible, effective, and sustainable platform for teaching medical students about the social determinants of health. Similar medical education programs in the future should seek to achieve a larger scale and to evaluate both students' educational experiences and community-defined outcomes.

    Introducción: El mantenimiento de unos adecuados estilos de vida, es de gran importancia para la prevención de enfermedades relacionadas con el embarazo durante las primeras etapas. Por ello, es necesario conocer el estado de salud general de las mujeres en edad fértil, y poder proporcionar un asesoramiento adecuado con el objetivo de mantener o mejorar su estado nutricional. El objetivo de este estudio fue evaluar los estilos de vida de las mujeres en edad fértil que planean un embarazo y estudiar las diferencias entre mujeres primíparas y multíparas en dichos estilos de vida. Métodos: Este estudio transversal incluyó un total de 4.471 mujeres españolas en edad fértil que está planeando un embarazo. La información se recogió, a través de un cuestionario, por profesionales de oficinas de farmacia. Resultados: El perfil de las mujeres reclutadas en edad fértil que planean un embarazo fue de poco más de treinta años (31,4 ± 4,8 años) y el 72,5% estaba buscando a su primer bebé. Ellas tenían una buena percepción tanto de su estado nutricional como de salud, y una dieta equilibrada pero con algunos hábitos no saludables. Cabe destacar que las mujeres primíparas presentaban menor riesgo de complicaciones relacionadas con salud pero eran mayores consumidoras de tabaco y alcohol, y menos consumidoras de leche fortificada, yodo y suplementos de hierro (p < 0,05), que las mujeres multíparas. Además, la población examinada mostró un patrón más sedentario en las mujeres primíparas en comparación con las mujeres multíparas, relativo a las horas / día tumbada, sentada y de pie. Conclusión: Las diferencias entre ambos grupos (primíparas y multíparas) ofrecen una gran oportunidad para promover hábitos saludables entre las mujeres en edad fértil, de acuerdo con el perfil de paridad, con el objetivo de prevenir estilos de vida no adecuados en embarazos futuros.

    Members of the Colorado Center for Lunar Dust and Atmospheric Studies (CCLDAS) initiated the Lunar Graduate Conference (LunGradCon), modeled after the highly successful Astrobiology Graduate Conference (AbGradCon). The purpose of this conference is to enhance the professional development of graduate students and early postdoctoral researchers by providing an opportunity to present and discuss scientific research in an environment of their peers. For the first two years, LunGradCon has been held as a one-day conference in conjunction with the NASA Lunar Science Institue's (NLSI) Lunar Science Forum at the NASA Ames Research Center. Activities include an invited overview talk on each of the NASA Lunar Science Institute's three main research areas (OF the Moon, ON the Moon, and FROM the Moon), submitted oral presentations from graduate students and postdoctoral researchers, and networking opportunities with established member of the lunar science community and the NLSI. In each of the first two years of LunGradCon, there have been 20-25 attendees, with about 15 of those presenting submitted talks. Each speaker received feedback forms from the other participants in order to improve on their presentation techniques. Participants also provided feedback on the conference as a whole in order to evaluate the content and provide suggestions for improvement in following years. Overall, the feedback has been extremely positive. This talk will summarize the achievements of past LunGradCons and plans for expansion of the conference to ensure a long-term positive impact on the early careers of future lunar, planetary and space science researchers.

    2015-10-01

    An important fraction of microbial diversity is harbored in strain individuality, so identification of conspecific bacterial strains is imperative for improved understanding of microbial community functions. Limitations in bioinformatics and sequencing technologies have to date precluded strain identification owing to difficulties in phasing short reads to faithfully recover the original strain-level genotypes, which have highly similar sequences. We present ConStrains, an open-source algorithm that identifies conspecific strains from metagenomic sequence data and reconstructs the phylogeny of these strains in microbial communities. The algorithm uses single-nucleotide polymorphism (SNP) patterns in a set of universal genes to infer within-species structures that represent strains. Applying ConStrains to simulated and host-derived datasets provides insights into microbial community dynamics.

    There is a need for culturally relevant nutrition programs targeted to underserved cancer survivors. Our aim was to examine the effect of a culturally based approach to dietary change on increasing fruit/vegetable (F/V) intake and decreasing fat intake among Hispanic breast cancer survivors. Participants were randomized to Intervention and Control groups. Diet recalls, detailed interviews, fasting blood, and anthropometric measures were collected at baseline, 3, 6, and 12 months. Hispanic women (n=70) with stage 0 to III breast cancer who completed adjuvant treatment and lived in New York City were randomized between April 2011 and March 2012. The Intervention group (n=34) participated in ¡Cocinar Para Su Salud!, a culturally based nine-session (24 hours over 12 weeks) intervention including nutrition education, cooking classes, and food-shopping field trips. The Control group (n=36) received written dietary recommendations for breast cancer survivors. Change at 6 months in daily F/V servings and percent calories from total fat were the main outcome measures. Linear regression models adjusted for stratification factors and estimated marginal means were used to compare changes in diet from baseline to 3 and 6 months. Baseline characteristics were the following: mean age 56.6 years (standard deviation 9.7 years), mean time since diagnosis 3.4 years (standard deviation 2.7 years), mean body mass index (calculated as kg/m²) 30.9 (standard deviation 6.0), 62.9% with annual household income ≤$15,000, mean daily servings of all F/V was 5.3 (targeted F/V 3.7 servings excluding legumes/juices/starchy vegetables/fried foods), and 27.7% of daily calories from fat. More than 60% in the Intervention group attended seven or more of nine classes, with overall study retention of 87% retention at 6 months. At month 6, the Intervention group compared with Control group reported an increase in mean servings of F/V from baseline (all F/V: +2.0 vs -0.1; P=0.005; targeted F/V: +2

    The impact of lifestyle on health is undeniable and effective healthy lifestyle promotion interventions do exist. However, this is not a fundamental part of routine primary care clinical practice. We describe factors that determine changes in performance of primary health care centers involved in piloting the health promotion innovation 'Prescribe Vida Saludable' (PVS) phase II. We engaged four primary health care centers of the Basque Healthcare Service in an action research project aimed at changing preventive health practices. Prescribe Healthy Life (PVS from the Spanish "Prescribe Vida Saludable) is focused on designing, planning, implementing and evaluating innovative programs to promote multiple healthy habits, feasible to be performed in routine primary health care conditions. After 2 years of piloting, centers were categorized as having high, medium, or low implementation effectiveness. We completed qualitative inductive and deductive analysis of five focus groups with the staff of the centers. Themes generated through consensual grounded qualitative analysis were compared between centers to identify the dimensions that explain the variation in actual implementation of PVS, and retrospectively organized and assessed against the Consolidated Framework for Implementation Research (CFIR). Of the 36 CFIR constructs, 11 were directly related to the level of implementation performance: intervention source, evidence strength and quality, adaptability, design quality and packaging, tension for change, learning climate, self-efficacy, planning, champions, executing, and reflecting and evaluating, with -organizational tracking added as a new sub-construct. Additionally, another seven constructs emerged in the participants' discourse but were not related to center performance: relative advantage, complexity, patients' needs and resources, external policy and incentives, structural characteristics, available resources, and formally appointed internal implementation

    An integral part of the Systems Engineering process is the creation of a Concept of Operations (ConOps) for a given system, with the ConOps initially established early in the system design process and evolved as the system definition and design matures. As Integration Engineers in NASA's Launch Services Program (LSP) at Kennedy Space Center (KSC), our job is to manage the interface requirements for all the robotic space missions that come to our Program for a Launch Service. LSP procures and manages a launch service from one of our many commercial Launch Vehicle Contractors (LVCs) and these commercial companies are then responsible for developing the Interface Control Document (ICD), the verification of the requirements in that document, and all the services pertaining to integrating the spacecraft and launching it into orbit. However, one of the systems engineering tools that have not been employed within LSP to date is a Concept of Operations. The goal of this paper is to research the format and content that goes into these various aerospace industry ConOps and tailor the format and content into template form, so the template may be used as an engineering tool for spacecraft integration with future LSP procured launch services. This tailoring effort was performed as the authors final Masters Project in the Spring of 2016 for the Stevens Institute of Technology and modified for publication with INCOSE (Owens, 2016).

    Villa-Torres, Laura; Fleming, Paul; Barrington, Clare

    2016-01-01

    The promotor de salud, or community health worker (CHW) role, is highly feminized and little is known about how men view their participation in CHW programs. We conducted in-depth interviews with Latino men in North Carolina to explore this gap. We used systematic coding and display procedures informed by Grounded Theory to analyze the data. Men described their communities as lacking cohesion, making integration of Latino immigrants difficult. Most did not consider themselves leaders or feel they had leaders in their communities. Their perceptions of the feminized CHW role as well as the volunteer or low-paid nature of CHW work conflicted with men’s provider role. They also did not think they could perform the CHW role because they lacked education, skills, and broad networks. Efforts to increase male participation in CHW programs in new Latino immigrant destinations will need to understand and address these gender and migration-related dynamics in order to engage both women and men in improving the health of their communities.

    To determine the prevalence of Helicobacter pylori in symptomatic outpatients in Red Rebagliati (EsSalud) from 2010 to 2013. An observational, transversal and analytical study. Records of outpatients with diagnostic 13C-urea breath test of Helicobacter pylori in the period 2010-2013 were reviewed. Of the 1711 patients, the overall prevalence of Helicobacter pylori was 45.5% (95% CI: 43.17-47.89) being higher in women than in men (47.1% vs. 42.1%, p=0.056). There were significant differences in age between infected and uninfected (44 vs. 39, p < 0.05), with association between age and the presence of Helicobacter pylori (p<0.001). The estimated prevalence in the pediatric population was 36.3% and was found positive in 201 (51.1%) women of childbearing age. Most (43.9%) came from the financial sector of the city. The prevalence of Helicobacter pylori in the study population was similar in both sexes and is related to age. The average socioeconomic status of Lima maintains the prevalence of Helicobacter pylori reported in the last years.

  3. Uneasy money: the Instituto Carlos Slim de la Salud, tobacco philanthropy and conflict of interest in global health

    Burch, Tiffany; Wander, Nathaniel; Collin, Jeff

    2015-01-01

    In May 2007, the Instituto Carso de la Salud—now Instituto Carlos Slim de la Salud (ICSS)—was endowed with US$500 million to focus on priority health issues in Latin America, notably issues of ‘globalisation and non-communicable diseases’. ICSS was soon criticised, however, on the grounds that its funding was derived from tobacco industry profits and that its founder Carlos Slim Hélu remained an active industry principal. Collaboration with ICSS was said to run counter to the WHO Framework Convention on Tobacco Control. The Institute's then Executive President Julio Frenk disputed these charges. This research employs an archive of tobacco industry documents triangulated with materials from commercial, media, regulatory and NGO sources to examine the financial relations between Slim and the tobacco industry. The paper analyses Slim's continuing service to the industry and role in ICSS. It demonstrates a prima facie conflict of interest between ICSS's health mission and its founder's involvement in cigarette manufacturing and marketing, reflected on ICSS's website as a resounding silence on issues of tobacco and health. It is concluded that the reliance of international health agencies upon the commercial sector requires more robust institutional policies to effectively regulate conflicts of interest. PMID:21088061

    This paper reviews a successful community-based education effort to minimize pesticide exposure to migrant and seasonal farmworkers and their families through innovative training curricula, informal participatory educational techniques and culturally sensitive outreach methods. In 2004, Migrant Clinicians Network, Inc., trained lay health educators, or promotoras de salud, from local agencies in southern New Mexico in pesticide safety and in ways to successfully promote safety information in the farmworker community. Through home visits and small group workshops, the promotoras trained 273 farmworkers and farmworker family members on ways to reduce exposures to pesticides in their homes and at work, with an emphasis on protecting children. The families received a Spanish language comic book that reinforced the pesticide safety information, emphasizing the health effects of acute and chronic pesticide exposure and steps to protect farmworker children from pesticide exposure. The project resulted in a significant increase in knowledge regarding the routes of exposure, the vulnerability of children, the signs and symptoms of pesticide poisonings and the ways to minimize pesticide exposures. Additionally, the project showed improved behaviors aimed at minimizing pesticide exposure through accidental poisonings in the home. This pilot project proved the efficacy of an in-home, one-on-one approach with a culturally appropriate educational comic book as an instrument to help transfer education to the community. Moreover, the educational method involving promotoras offers a training-of- trainer approach that is easy to implement and potentially replicate.

    The promotor de salud, or community health worker (CHW) role, is highly feminized and little is known about how men view their participation in CHW programs. We conducted in-depth interviews with Latino men in North Carolina to explore this gap. We used systematic coding and display procedures informed by Grounded Theory to analyze the data. Men described their communities as lacking cohesion, making integration of Latino immigrants difficult. Most did not consider themselves leaders or feel they had leaders in their communities. Their perceptions of the feminized CHW role as well as the volunteer or low-paid nature of CHW work conflicted with men's provider role. They also did not think they could perform the CHW role because they lacked education, skills, and broad networks. Efforts to increase male participation in CHW programs in new Latino immigrant destinations will need to understand and address these gender and migration-related dynamics in order to engage both women and men in improving the health of their communities.

    Project Salud evaluates the efficacy of a community-based intervention to reduce risk behaviors and enhance factors for HIV-preventative behaviors. A randomized controlled trial of 278 high risk Latino migrant workers was conducted between 2008 and 2010. Participants completed an audio computer-assisted self-interview questionnaire at baseline and 3- and 9-month post-intervention follow-ups. Participants were randomly assigned to the community-based intervention (A-SEMI) or the health promotion condition (HPC). Both interventions consisted of four 2.5-hour interactive sessions and were structurally equivalent in administration and format. Relative to the comparison condition, A-SEMI participants reported more consistent condom use, were less likely to report never having used condoms, and were more likely to have used condoms at last sexual encounter during the past 90 and 30 days. A-SEMI participants also experienced a positive change in regard to factors for HIV-preventive behaviors over the entire 9-month period. Our results support the implementation of community-based, culturally tailored interventions among Latino migrant workers.

    This study assessed effectiveness of an educational community intervention taught by promotoras de salud in reducing cardiovascular disease (CVD) risk among Hispanics using a structural equation modeling (SEM) approach. Model development was guided by a social ecological framework proposing CVD risk reduction through improvement of protective health behaviors, health beliefs, contextual and social factors. Participants were 328 Hispanic adults with at least one CVD risk factor. SEM analyses assessed direct and indirect effects of intervention participation on CVD risk (Framingham score) and latent variables nutrition intake and health beliefs. The model fit was adequate (root mean square error of approximation = .056 [90% confidence interval = .040, .072], comparative fit index = .967, normed fit index = .938, nonnormed fit index = .947). Intervention participation was associated with improved nutritional consumption, but not lower CVD risk. Stronger health beliefs predicted healthier nutritional habits. This project provided evidence for the adequacy of a conceptual framework that can be used to elicit new pathways toward CVD risk reduction among at-risk Hispanic populations.

    Genes con-10 and con-6 in Neurospora crassa are activated during conidiation or after illumination of vegetative mycelia. Light activation requires the white-collar complex (WCC), a transcription factor complex composed of the photoreceptor WC-1 and its partner WC-2. We have characterized the photoactivation of con-10 and con-6, and we have identified 300bp required for photoactivation in the con-10 promoter. A complex stimulus-response relationship for con-10 and con-6 photoactivation suggested the activity of a complex photoreceptor system. The WCC is the key element for con-10 activation by light, but we suggest that other photoreceptors, the cryptochrome CRY-1, the rhodopsin NOP-1, and the phytochrome PHY-2, modify the activity of the WCC for con-10 photoactivation, presumably through a repressor. In addition we show that the regulatory protein VE-1 is required for full photocarotenogenesis. We propose that these proteins may modulate the WCC in a gene-specific way.

    We present Caffe con Troll (CcT), a fully compatible end-to-end version of the popular framework Caffe with rebuilt internals. We built CcT to examine the performance characteristics of training and deploying general-purpose convolutional neural networks across different hardware architectures. We find that, by employing standard batching optimizations for CPU training, we achieve a 4.5× throughput improvement over Caffe on popular networks like CaffeNet. Moreover, with these improvements, the end-to-end training time for CNNs is directly proportional to the FLOPS delivered by the CPU, which enables us to efficiently train hybrid CPU-GPU systems for CNNs.

    This article investigates the ostensibly paradoxical relationship that exists between the theme of excessive love, as suggested by the title of Abhishek Chaubey's film Dedh Ishqiya (2014), and the actual representation of it in the movie, which is not only restrained and disproportionate, but is also looked at with suspicion and contempt. It examines the logic of this seeming contradiction through the other two related themes that Chaubey's chef-d'œuvre foregrounds, namely that of intelligence and female desire. The quest for financial autonomy that the female protagonists of the movie are involved in-a necessary pre-condition for leading independent lives-is so inextricably intertwined with manipulation, dexterity, and subterfuge, that any overt expression of homoerotic female desire can only jeopardize their existing possibilities of self-aggrandizement. The heteronormative arrangements of Begum Para's palace thus constitute the elaborate mise en scène, behind which female desire is enacted through a politics of intelligence, resourcefulness, discretion, and anonymity. Through this strategic negotiation, which is also a tactical necessity, the female protagonists are not only able to con the con men in the movie, but also imagine alternative subject positions that recognize the need for both pragmatism and expediency as well as deconstructing heteropatriarchal economies of desire.

    There is a need for culturally relevant nutrition programs targeted to underserved cancer survivors. Our aim was to examine the effect of a culturally based approach to dietary change on increasing fruit/vegetable (F/V) intake and decreasing fat intake among Hispanic breast cancer survivors. Participants were randomized to Intervention and Control groups. Diet recalls, detailed interviews, fasting blood, and anthropometric measures were collected at baseline, 3, 6, and 12 months. Hispanic women (n=70) with stage 0 to III breast cancer who completed adjuvant treatment and lived in New York City were randomized between April 2011 and March 2012. The Intervention group (n=34) participated in ¡Cocinar Para Su Salud!, a culturally based nine-session (24 hours over 12 weeks) intervention including nutrition education, cooking classes, and food-shopping field trips. The Control group (n=36) received written dietary recommendations for breast cancer survivors. Change at 6 months in daily F/V servings and percent calories from total fat were the main outcome measures. Linear regression models adjusted for stratification factors and estimated marginal means were used to compare changes in diet from baseline to 3 and 6 months. Baseline characteristics were the following: mean age 56.6 years (standard deviation 9.7 years), mean time since diagnosis 3.4 years (standard deviation 2.7 years), mean body mass index (calculated as kg/m(2)) 30.9 (standard deviation 6.0), 62.9% with annual household income ≤$15,000, mean daily servings of all F/V was 5.3 (targeted F/V 3.7 servings excluding legumes/juices/starchy vegetables/fried foods), and 27.7% of daily calories from fat. More than 60% in the Intervention group attended seven or more of nine classes, with overall study retention of 87% retention at 6 months. At month 6, the Intervention group compared with Control group reported an increase in mean servings of F/V from baseline (all F/V: +2.0 vs -0.1; P=0.005; targeted F

    We tested the effectiveness of a lay health worker intervention to increase breast and cervical cancer screening among low-income Hispanic women. Participants were women 50 years and older who were nonadherent to mammography (n = 464) or Papanicolaou (Pap) test (n = 243) screening guidelines. After the collection of baseline data, lay health workers implemented the Cultivando la Salud (CLS; Cultivating Health) intervention. Data collectors then interviewed the participants 6 months later. At follow-up, screening completion was higher among women in the intervention group than in the control group for both mammography (40.8% vs 29.9%; P < .05) and Pap test (39.5% vs 23.6%; P < .05) screening. In an intent-to-treat analysis, these differences remained but were not significant. The intervention increased mammography self-efficacy, perceived susceptibility, perceived survivability, perceived benefits of mammography, subjective norms, and processes of change. The intervention also significantly increased Pap test self-efficacy, perceived benefits of having a Pap test, subjective norms, and perceived survivability of cancer. It did not change Pap test knowledge, perceived susceptibility, or perceptions about negative aspects of Pap test screening. Our results add to the evidence concerning the effectiveness of lay health worker interventions for increasing Pap test screening and mammography. Future research should explore the effectiveness of CLS in other Hispanic groups, the mechanisms through which interpersonal communication influences decisions about screening, and how effective interventions such as CLS can best be adopted and implemented in community-based organizations or other settings.

    Over the past several decades, Puerto Ricans have faced increased health threats from chronic diseases, particularly diabetes and hypertension. The patient-provider relationship is the main platform for individual disease management, whereas the community, as an agent of change for the community's health status, has been limited in its support of individual health. Likewise, traditional research approaches within communities have placed academic researchers at the center of the process, considering their knowledge was of greater value than that of the community. In this paradigm, the academic researcher frequently owns and controls the research process. The primary aim is contributing to the scientific knowledge, but not necessarily to improve the community's health status or empower communities for social change. In contrast, the community-based participatory research (CBPR) model brings community members and leaders together with researchers in a process that supports mutual learning and empowers the community to take a leadership role in its own health and well-being. This article describes the development of the community-campus partnership between the University of Puerto Rico School of Medicine and Piñones, a semi-rural community, and the resulting CBPR project: "Salud para Piñones". This project represents a collaborative effort to understand and address the community's health needs and health disparities based on the community's participation as keystone of the process. This participatory approach represents a valuable ally in the development of long-term community-academy partnerships, thus providing opportunities to establish relevant and effective ways to translate evidence-based interventions into concrete actions that impact the individual and community's wellbeing.

    In 2003, Mexico's Seguro Popular de Salud (SPS), was launched as an innovative financial mechanism implemented to channel new funds to provide health insurance to 50 million Mexicans and to reduce systemic financial inequities. The objective of this article is to understand the complexity and dynamics that contributed to the adaptation of the policy in the implementation stage, how these changes occurred, and why, from a complex and adaptive systems perspective. A complex adaptive systems (CAS) framework was used to carry out a secondary analysis of data obtained from four SPS's implementation evaluations. We first identified key actors, their roles, incentives and power, and their responses to the policy and guidelines. We then developed a causal loop diagram to disentangle the feedback dynamics associated with the modifications of the policy implementation which we then analyzed using a CAS perspective. Implementation variations were identified in seven core design features during the first 10 years of implementation period, and in each case, the SPS's central coordination introduced modifications in response to the reactions of the different actors. We identified several CAS phenomena associated with these changes including phase transitions, network emergence, resistance to change, history dependence, and feedback loops. Our findings generate valuable lessons to policy implementation processes, especially those involving a monetary component, where the emergence of coping mechanisms and other CAS phenomena inevitably lead to modifications of policies and their interpretation by those who implement them. These include the difficulty of implementing strategies that aim to pool funds through solidarity among beneficiaries where the rich support the poor when there are no incentives for the rich to do so. Also, how resistance to change and history dependence can pose significant challenges to implementing changes, where the local actors use their significant power

    Data are limited on the efficacy of health-focused interventions for young, low-acculturated Latino women. Because breast cancer is the most commonly diagnosed cancer and the most common cause of cancer mortality in this population, combined interventions that address both early detection and dietary patterns could help reduce both morbidity and mortality associated with breast cancer in this underserved population. Mujeres Felices por ser Saludables was randomized intervention study designed to assess the efficacy of an 8-month combined dietary and breast health intervention to reduce fat and increase fiber intake as well as to increase the frequency and proficiency of breast self-examination (BSE) and reduce anxiety related to BSE among Latinas. Blocked randomization in blocks of 6 was used to randomize 256 20- to 40-year-old Latinas to the intervention (n = 127) or control group (n = 129). The intervention group attended an 8-month multicomponent education program designed specifically for low-acculturated Latinas. The control group received mailed health education material on a schedule comparable to the intervention. A total of 195 women (76.2%) completed both the baseline and 8-month follow-up interviews. The intervention and control groups were similar on baseline sociodemographic characteristics. At the 8-month follow up, the intervention group reported lower dietary fat (P < .001) and higher fiber intake (p = .06); a higher proportion reported practicing BSE at the recommended interval (p < .001) and showed improved BSE proficiency (p < .001) compared to the control group. BSE-related anxiety was low for both groups at baseline, and no difference in reduction was observed. This project provides a successful model for achieving dietary change and improving breast health behavior in young, low-acculturated Latinas.

    For some time, the most of reports have been being disseminated by way of scientific journals, bibliometric studies therefore being fundamental to the characterization and evaluation thereof. The purpose of this study is that of characterizing the Revista Española de Salud Pública based on the original articles published therein throughout the 1991-2000 period. Original articles published in the Revista Española de Salud Pública throughout the 1991-2000 period, all inclusive. A study has been made of the following variables: number of original articles, collaboration index or number of signing authors per study, productivity index, geographical spread and main subject. Throughout the 1991-2000 period, 290 original studies (52.3%) of a total of 555 studies were published. The number of originals averaged 29 originals/year A 4.5 degree of collaboration was found to exist for this journal (number signing authors/number originals) for the period under study. The annual of originals by Autonomous Community reveals in the Autonomous Community of Madrid (20.7%), Autonomous Community of Valencia (16.4%), Andalusia (16.1%) and Catalunya (10.0%) have published studies every year throughout the ten-year period under study. The most prevalent subject of all was that related to "Communicable disease" (86 originals), Primary Health Care" (34) and "Environmental pollution" (21). Generally speaking, it apparently follows that the Revista Española de Salud Pública continues to fall within the output-related indicators of other Spanish and foreign journals and that it has also evolved in keeping with the trend proper of scientific output in the biomedical field. Although "Communicable diseases" are not the main cause of mortality, they continue being the main subject more frequently studied.

    In 2001, the National Heart, Lung, and Blood Institute partnered with the National Council of La Raza to conduct a pilot test of its community-based outreach program Salud Para Su Corazón (Health for Your Heart), which aims to reduce the burden of morbidity and mortality associated with cardiovascular disease among Latinos. The effectiveness of promotores de salud (community health workers) in improving heart-healthy behaviors among Latino families participating in the pilot program at seven sites was evaluated. Data on the characteristics of the promotores in the Salud Para Su Corazón program were compiled. Promotores collected data on family risk factors, health habits, referrals and screenings, information sharing, and program satisfaction from 223 participating Latino families (320 individual family members) through questionnaires. Paired t tests and chi-square tests were used to measure pretest-posttest differences among program participants. Results demonstrated the effectiveness of the promotora model in improving heart-healthy behaviors, promoting community referrals and screenings, enhancing information sharing beyond families, and satisfying participants' expectations of the program. The main outcome of interest was the change in heart-healthy behaviors among families. The community outreach model worked well in the seven pilot programs because of the successes of the promotores and the support of the community-based organizations. Successes stemmed in part from the train-the-trainer approach. Promotoria, as implemented in this program, has the potential to be integrated with a medical model of patient care for primary, secondary, and tertiary prevention.

    Hydrological processes in the humid tropics are poorly understood and an important topic when it comes to water management in the seasonal tropics. The Smithsonian Tropical Research Institute, Panama Canal Watershed Experiment, Agua Salud Project, seeks to understand these processes and quantify the long-term effects of different land cover and uses across the Panama Canal Watershed. One of the project’s main objectives is to understand how reforestation effects seasonal stream flows. To meet this objective, a baseline characterization of hydrology on the small catchment scale is being assessed across different land uses typical in rural Panama. The small experimental catchments are found within Panama’s protected Soberania National Park and the adjacent headwaters of the Agua Salud and Mendoza Rivers, all of which are part of the greater Panama Canal Watershed. The land uses being monitored include a variety of control catchments as well as treated pasture sites. The catchments used for this study include a mature old regrowth forest, a 50% deforested or mosaic regrowth site, an active pasture and a monoculture invasive grass site (saccharum spontaneum) as experimental controls and two treated catchments that were recently abandoned pastures converted to teak and native species timber plantations. Installed instrumentation includes a network of rain gauges, v-notched weirs, atmometers, an eddy covariance system and an assortment of meteorological and automated geochemical sampling systems. Spatial, rainfall, runoff and ET data across these six geologically and topographically similar catchments are available from 2009 and 2010. Classic water balance and paired catchment techniques were used to compare the catchments on an annual, seasonal, and event basis. This study sets the stage for hydrologic modeling and for better understanding the effects of vegetation and land-use history on rainfall-runoff processes for the Agua Salud Project and Panama Canal

    When characterizing a scientific journal from the bibliometric standpoint, it is of importance to know how many authors were involved in the studies published as well as the geographical areas where these authors are located and the type of institutions by which they are employed. The aim of this article is that of analyzing the geographical spread of these authors and the institutions by which they are employed, as well as its evolution as regards the original articles published in the Revista Española de Salud Pública throughout the 1991-2000 period. Of the original articles published in the Revista Española de Salud Pública throughout the studied ten-year period, a calculation has been made as to the total number of authors, the number of occasional authors (authors having published solely one article), transitivity index, the ratio between the number of male and female authors, the productivity of the authors and their institutions and the spread of authors and the institutions by which they are employed by Autonomous Communities. Of the original articles published in the Revista Española de Salud Pública throughout the 1991-2000 period, a total of 1,052 different authors were involved, 1,000 of whom were Spanish and 52 foreigners. The ratio of male authors to female authors for the period in question was 1.29. The Autonomous Communities from which the largest number of authors came were Community of Madrid (16.3%), Andalusia (13.4%) and the Community of Valencia (12.5%). The institutions by which the authors are employed are located most often in Community of Madrid (16.5%), in Community of Valencia (11.3%) and Andalusia and Catalonia (10.5%). A total of 37.6% of the authors work at centers devoted to health care, followed by authors who work at Universities (26.3%). On calculating the spread of the type of institution by Autonomous Communities, in the Community of Madrid and in the Community of Valencia and Andalusia, the most frequent institution is

    In the last two decades, research has dramatically increased the knowledge of cannabinoids biology and pharmacology. In mammals, compounds with properties similar to active components of Cannabis sativa, the so called ‘endocannabinoids', have been shown to modulate key cell-signalling pathways involved in cancer cell growth, invasion and metastasis. To date, cannabinoids have been licensed for clinical use as palliative treatment of chemotherapy, but increased evidences showed direct antiproliferative actions of cannabinoid agonists on several tumour cells in vitro and in animal models. In this article, we will review the principal molecular pathways modulated by cannabinoids on cancer and summarize pros and cons evidence on the possible future use of endocannabinoid-based drugs in cancer therapy.

    In this review we aim to provide an overview of the most important ethical pros and cons of stem cell derived gametes (SCD-gametes), as a contribution to the debate about reproductive tissue engineering. Derivation of gametes from stem cells holds promising applications both for research and for clinical use in assisted reproduction. We explore the ethical issues connected to gametes derived from embryonic stem cells (both patient specific and non-patient specific) as well as those related to gametes derived from induced pluripotent stem cells. The technology of SCD-gametes raises moral concerns of how reproductive autonomy relates to issues of embryo destruction, safety, access, and applications beyond clinical infertility.

    Endoscopy plays a pivotal role for diagnosis and assessment of disease activity and extent in patients with inflammatory bowel diseases. International guidelines recommend the use of endoscopic scoring systems for evaluation of the prognosis and efficacy of medical treatments. Ideal scoring systems are easy to use, reproducible, reliable, responsive to changes, and validated in different clinical settings in order to guide therapeutic strategies. However, currently available endoscopic scoring systems often appear as complex for routine endoscopy and suffer from insufficient interobserver agreement and lack of formal validation which often limit their use in clinical trials. Here, we describe the role of endoscopic scoring systems in inflammatory bowel diseases focusing on pros and cons in the era of advanced endoscopic imaging and mucosal healing.

  7. Gradient Optimization for Analytic conTrols - GOAT

    Quantum optimal control becomes a necessary step in a number of studies in the quantum realm. Recent experimental advances showed that superconducting qubits can be controlled with an impressive accuracy. However, most of the standard optimal control algorithms are not designed to manage such high accuracy. To tackle this issue, a novel quantum optimal control algorithm have been introduced: the Gradient Optimization for Analytic conTrols (GOAT). It avoids the piecewise constant approximation of the control pulse used by standard algorithms. This allows an efficient implementation of very high accuracy optimization. It also includes a novel method to compute the gradient that provides many advantages, e.g. the absence of backpropagation or the natural route to optimize the robustness of the control pulses. This talk will present the GOAT algorithm and a few applications to transmons systems.

    Carnegie Mellon U. and ORNL`s Robotics and Process Systems Division are developing a state-of-the-art robot operator control station (RoboCon) with standardized hardware and software control interfaces to be adaptable to a variety of remote and robotic equipment currently funded by DOE`s Office of Science & Technology Robotics Technology Development Program. The human operation and telerobotic and supervisory control of sophisticated and remote and robotic systems is a complex, tiring, and non-intuitive activity. Since decontamination & decommissioning, selective equipment removal, mixed waste operations, and in-tank cleanup are going to be a major future activity in DOE environmental restoration and waste management cleanup agenda, it seems necessary to utilize an operator control station and interface which maximizes operator comfort and productivity.

    We present Caffe con Troll (CcT), a fully compatible end-to-end version of the popular framework Caffe with rebuilt internals. We built CcT to examine the performance characteristics of training and deploying general-purpose convolutional neural networks across different hardware architectures. We find that, by employing standard batching optimizations for CPU training, we achieve a 4.5× throughput improvement over Caffe on popular networks like CaffeNet. Moreover, with these improvements, the end-to-end training time for CNNs is directly proportional to the FLOPS delivered by the CPU, which enables us to efficiently train hybrid CPU-GPU systems for CNNs.

    The wear products and adverse reactions that occur on bearing surfaces represent one of the greatest challenges in prosthetic replacements, as the latter experience increasing demands due to the large number of young and older adult patients that have a long life expectancy and remarkable activity. The purpose of this review is to analyze the pros and cons of the new advances in the bearing components of the articular surfaces of current total hip arthroplasties. We also discuss the strategies used historically, their problems, results and the surgeon's role in prescribing the tribologic couple that best fits each patient's needs. We conclude with practical recommendations for the prescription and management of the latest articular couples for total hip arthroplasty.

    In the last two decades, research has dramatically increased the knowledge of cannabinoids biology and pharmacology. In mammals, compounds with properties similar to active components of Cannabis sativa, the so called 'endocannabinoids', have been shown to modulate key cell-signalling pathways involved in cancer cell growth, invasion and metastasis. To date, cannabinoids have been licensed for clinical use as palliative treatment of chemotherapy, but increased evidences showed direct antiproliferative actions of cannabinoid agonists on several tumour cells in vitro and in animal models. In this article, we will review the principal molecular pathways modulated by cannabinoids on cancer and summarize pros and cons evidence on the possible future use of endocannabinoid-based drugs in cancer therapy.

    An integrated well log, biostratigraphic, and seismic stratigraphic study of Miocene to Recent deltaic sediments deposited in the Nam Con Son Basin offshore from southern Vietnam shows the influence of eustacy and tectonics on sequence development. Sediments consist of Oligocene non-marine rift-basin fill (Cau Formation), early to middle Miocene tide-dominated delta plain to delta front sediments (TB 1.5 to TB 2.5, Due and Thong Formations), and late Miocene to Recent marine shelf sediments (TB. 2.6 to TB 3.1 0, Mang Cau, Nam Con Son, and Bien Dong Formations). Eustacy controlled the timing of key surfaces and sand distribution in the tectonically-quiet early Miocene. Tectonic effects on middle to late Miocene sequence development consist of thick transgressive systems tracts due to basin-wide subsidence and transgression, sand distribution in the basin center, and carbonate sedimentation on isolated fault blocks within the basin. Third-order sequence boundaries (SB) are identified by spore peaks, sand stacking patterns, and channel incision. In the basin center, widespread shale beds with coal occur above sequence boundaries followed by transgressive sandstone units. These TST sandstones merge toward the basin margin where they lie on older HST sandstones. Maximum flooding surfaces (MFS) have abundant marine microfossils and mangrove pollen, a change in sand stacking pattern, and often a strong seismic reflection with downlap. Fourth-order genetic-type sequences are also interpreted. The MFS is the easiest marker to identify and correlate on well logs. Fourth-order SB occur within these genetic units but are harder to identify and correlate.

    The early phase of the ConA-induced inflammatory ascites was studied, with special reference to histamine. Concanavalin A (ConA), a cell-surface binding lectin was injected i.p. (25 mg/kg bw) to mice. After 1 h the animals were killed, the ascitic fluid collected and measured. Other agents were injected s.c., 10 min before the ConA-challenge. Exogenous histamine markedly inhibited the ConA-induced ascites. Release of endogenous vasoactive agents from the mast cells by Compound 48/80 had a similar, but slight effect. Cromolyn, a mast cell stabilizing agent, and chloropyramine, a histamine H1 receptor antagonist was ineffective. Although histamine increases endothelial permeability, it did not enhance the formation of ascitic fluid, on the contrary, it inhibited the ConA-induced ascites, presumably due to its known hypotonic effect. It is concluded that ConA-induced ascites is not mediated by mast cell histamine.

The article describes the development of the Public Health Institutes. arising from the introduction and development of scientific and laboratory based medicine and the introduction of vaccination and sanitation with the control of water and food. At about the same time, the discoveries in microbiology and immunology were produced, being the research activities incardinated with the practical advances in the control of products. To cope with the practical needs, Institutions were created with the responsibility of providing smallpox vaccine but incorporating very soon production of sera and other vaccines and water and sanitation control and foods control. At the same time. colonization of countries specially in Africa, South East Asia and explorations in Central America confront the Europeans with new diseases and the need of laboratories where to study them. These circumstances gave rise to the birth of the Central Public Health Laboratories and the National institutes of Health at the beginning of the XX century in many countries. In Spain, the Spanish Civil War was a breaking point in the development of such an institution that finally was reinvented with the creation of the Instituto de Salud Carlos III, in 1986, incorporating research and epidemiological surveillance and control of diseases and also the responsibilities of the Food and Drug Control, lately separated from it.

    We evaluated the effectiveness of the Salud y Bienestar program to deliver diabetes education in the Hispanic population in the United States. This program uses a community outreach model where community health promoters are trained and then they deliver education to other community members regarding diabetes disease, risk factors, and ways to prevent and control disease. This intervention applies a one-group pre- and post-test design to improve diabetes knowledge. The intervention carried out in the states of California, Texas, and Washington DC. A total of 1,413 participants were enrolled. Of these, 73% were females, 46% were 65 years or older, 59% were Mexican, 64% had at least elementary education, 56% had lived in the US for more than 20 years, and 38% participants were self-reported diabetic. Among diabetic participants, a significant improvement was observed on diabetes knowledge when comparing pre- and post-test scores (13.7 vs. 18.6, P < 0.001; Cohen's d = 1.2). Among non-diabetic participants, diabetes knowledge also increased significantly after one-single training session (12.9 vs. 18.2, P < 0.001; Cohen's d = 1.2). The Salud y Bienestar program conducted by community health workers was effective approach to improving diabetes knowledge in the Hispanic population.

    To determine the changes in the levels of dissatisfaction of the external users of the Instituto Nacional de Salud del Niño, in Lima, Peru. Observational study based on a software to evaluate surveys completed by health care users (Software de Evaluación de Encuestas de Usuarios en Salud - SEEUS). The population consisted of every person accompanying external users to outpatient visits, inpatient visits or emergency treatment in the years 2008, 2009 and 2010. To calculate the sample size, last year's proportion of users dissatisfied with each service was used, with an estimated error of 5% at a 95% confidence level. A sample of 2051 people was obtained, which revealed a decreasing trend in the levels of dissatisfaction with outpatient visits, and an increased dissatisfaction in the medical capabilities dimension for hospitalization and emergency services. In addition, a dissatisfaction index lower than 0.20 was registered in the medical capabilities dimension for outpatient visits. In contrast, the highest dissatisfaction indexes were registered in the hygiene dimension for 2009 (0.25) and 2010 (0.25), and in the others dimension for emergency services in 2009 (0.25). The dimensions showing an increase in the dissatisfaction index were tangible aspects, hygiene and others for hospitalization and emergency services. On the other hand, the medical capabilities dimension for outpatient visits showed a decrease in the level of dissatisfaction over the evaluated period.

    Background Many states enforce Certificate of Need (CON) regulations for cardiac procedures, but little is known about how CON affects utilization. We assessed the association between cardiac CON regulations, availability of revascularization facilities, and revascularization rates. Methods We determined when state cardiac CON regulations were active and obtained data for Medicare beneficiaries ages 65 and older who received coronary artery bypass graft surgery (CABG) or a percutaneous coronary intervention (PCI) between 1989 and 2002. We compared the number of hospitals performing revascularization and patient utilization in states with and without CON regulations, and in states which discontinued CON regulations during 1989-2002. Results Each year, the per capita number of hospitals performing CABG and PCI was higher in states without CON (3.7 per 100,000 elderly for CABG, 4.5 for PCI in 2002), compared with CON states (2.5 for CABG, 3.0 for PCI in 2002). Multivariate regressions that adjusted for market and population characteristics found no difference in CABG utilization rates between states with and without CON (p=.7). However, CON was associated with 19.2 percent fewer PCIs per 1,000 elderly (p=.01), equivalent to 322,526 fewer PCIs for 1989-2002. Among most states that discontinued CON, the number of hospitals performing PCI rose in the mid 1990s, but there were no consistent trends in the number of hospitals performing CABG or in PCIs or CABGs per capita. Conclusions CON restricts the number of cardiac facilities, but its effect on utilization rates may vary by procedure. PMID:17893007

  2. Laparoscopy for inflammatory bowel disease: pros and cons.

    1998-04-01

    The role of laparoscopic surgery in the treatment of colorectal malignancies is still under investigation, although it can offer significant benefits to many patients with inflammatory bowel disease (IBD). The aim of this study was to assess the pros and cons of the laparoscopic management of IBD. Data were obtained from a review of the literature published since 1992, when the first report of laparoscopic surgery for IBD appeared in print. From 1992 to 1997 several series of laparoscopic colorectal surgery for the management of IBD have been reported. A close evaluation of these studies revealed that laparoscopy in patients with terminal ileal Crohn's disease or anal Crohn's disease in need of fecal diversion offers significant advantages compared to laparotomy, including decreased pain, length of hospitalization, and disability. An additional bonus is improved cosmesis and a reduction in symptomatic postoperative adhesions. These many benefits can be achieved without any increase in morbidity or expense. Conversely, the use of this technology for restorative proctocolectomy in patients with mucosal ulcerative colitis is associated with a longer operative time and an increased incidence of both intra- and postoperative complications compared to laparotomy. Laparoscopic colorectal surgery can thus be advantageous for treatment of terminal ileal Crohn's disease but cannot be routinely justified for the treatment of mucosal ulcerative colitis.

  3. Pros and cons of circumcision: an evidence-based overview.

    Based on three large randomized controlled trials (RCTs) conducted in Africa, it can clearly be stated that circumcision lowers the risk of infection with the human immunodeficiency virus (HIV) and some sexually transmitted infections (STIs) among males in settings of high HIV and STI endemicity. Similar effects on STI risk may exist for females, although this may result from an indirect effect of decreasing risk of infection among male partners. It is unknown whether circumcision prevents HIV acquisition in men who have sex with men (MSM), although there might be a protective effect for men who engage mainly in insertive anal intercourse. When the effects of adult circumcision on sexual function and satisfaction of men are examined, high-quality evidence strongly supports lack of harm. Whether circumcision alters sexual satisfaction of female partners is not known as fewer and smaller studies reported conflicting results. Circumcision rarely causes serious complications if practiced by trained practitioners, in a sterile setting, and with a proper follow-up. These conclusions are limited by the lack of high-quality data from areas outside of Africa. RCTs have not been conducted to assess the effects of circumcising infants or MSM. Circumcision has well-proven benefits for people residing in areas with high prevalence of STIs, including HIV, and is not unethical for those who choose to be circumcised or have their children circumcised on religious, social, or cultural grounds. For many others, a definite pro or con recommendation, based on a risk-benefit ratio, cannot be made.

    Percutaneous coronary intervention is a mainstay in the management of symptomatic or high-risk coronary artery disease. The bulk of clinical evidence and experience underlying this fact relies, however, on relatively young patients. Indeed, few data of very limited quality are available which adequately define the risk-benefit and cost-benefit profile of coronary angioplasty and stenting in very old subjects, such as those of 90 years of age or older (i.e., nonagenarians). The aim of this review is to provide a concise, yet practical, synthesis of the available evidence on percutaneous coronary revascularization in the very elderly. The main arguments elaborated upon are to what extent we can extrapolate findings from studies including younger patients to nonagenarians, whether we should provide higher priority to prognosis or quality of life in such patients, and whether we can afford to allocate vast resources to care for such subjects in an era of financial constraints. Our review of 18 studies and 1082 patients suggest that percutaneous coronary intervention is feasible and associated with acceptable short- and long-term results in this population, which is nonetheless fraught with a high mortality risk irrespective of the revascularization procedure. Accordingly, the pros and cons of percutaneous coronary intervention should be carefully weighed when considering this treatment in nonagenarians. PMID:23610578

    The unique structural hallmark of the intervertebral disc has made its central composition, the nucleus pulposus (NP), excluded from the immunologic tolerance. Consequently, the intervertebral disc is identified as an immune-privileged organ. Traditionally, local detrimental immune activities caused by NP at the lesion sites of the disc are noted as a significant factor contributing to disc degeneration. However, given the beneficial activities of immune cells in other immune-privileged sites on basis of current evidence, the degenerate disc might need the assistance of a subpopulation of immune cells to restore its structure and lessen inflammation. In addition, the beneficial impact of immune cells can be seen in the absorption of the herniated NP, which is an important factor causes the mechanical compression of nerve roots. Consequently, a modulated immune network in degenerate disc is essential for the restoration of this immune-privileged organ. Until now, the understandings of immune response in disc degeneration still rest on the harmful aspect. Further studies are needed to explore its beneficial influence. Accordingly, there are no absolutely the pros and cons in terms of immune reactions caused by NP. PMID:23696917

  7. Pros and cons of screening for occult Cushing syndrome.

    PubMed

    2011-03-22

    Systematic screening studies performed mainly in patients with diabetes mellitus have revealed an unexpectedly high prevalence of occult Cushing syndrome. Such studies may provide a rationale for systematically screening obese patients with type 2 diabetes mellitus. However, a screening strategy is only justified if it is supported by enough evidence of its efficacy and if the benefits will outweigh drawbacks. To date, the natural history of occult Cushing syndrome and its possible effect on long-term morbidity are unknown. The clinical spectrum of occult Cushing syndrome and its relatively low prevalence may potentially negatively affect the performance of endocrine tests used to diagnose overt Cushing syndrome and generate false positives. Whether the cure of occult Cushing syndrome favorably influences clinical outcomes and is more beneficial than treatment of diabetes mellitus and cardiovascular risk factors with currently available pharmacological tools remains to be demonstrated. Last, the acceptability of a screening program by professionals and the health-care system in terms of workload and costs is highly questionable. Thus, an assessment of the indications for and against screening for occult Cushing syndrome on the basis of currently available data suggests that, to date, the cons surpass the pros.

    Ulcerative colitis (UC) is a chronic inflammatory disease characterized by diffuse mucosal inflammation limited to the colon and rectum. Although a complete medical cure may not be possible, UC can be treated with medications that induce and maintain remission. The medical management of this disease continues to evolve with a goal to avoid colectomy and ultimately alter the natural history of UC. Emergence of antitumor necrosis factor-α (TNF-α) agents has expanded the medical armamentarium. 5-Aminosalicylates continue to be used in mild to moderate UC and corticosteroids are mainly used for induction of remission with immunomodulators (6-mercaptopurine/azathiopurine/methotrexate) being applied as steroid-sparing agents for maintenance therapy. Infliximab has been approved by the U.S. Food and Drug Administration and used in the treatment of moderate to severe UC; nevertheless, its use may be associated with significant adverse effects and have a negative impact on the postoperative course should the patients undergo restorative proctocolectomy. In addition, there is always a concern about patients' compliance to medical therapy, cost of medications, and risk for UC-associated dysplasia. The authors discuss the pros and cons of medications used in the treatment of UC. PMID:22131893

  9. Pros, Cons, and Alternatives to Weight Based Cost Estimating

    2011-01-01

    Many cost estimating tools use weight as a major parameter in projecting the cost. This is often combined with modifying factors such as complexity, technical maturity of design, environment of operation, etc. to increase the fidelity of the estimate. For a set of conceptual designs, all meeting the same requirements, increased weight can be a major driver in increased cost. However, once a design is fixed, increased weight generally decreases cost, while decreased weight generally increases cost - and the relationship is not linear. Alternative approaches to estimating cost without using weight (except perhaps for materials costs) have been attempted to try to produce a tool usable throughout the design process - from concept studies through development. This paper will address the pros and cons of using weight based models for cost estimating, using liquid rocket engines as the example. It will then examine approaches that minimize the impct of weight based cost estimating. The Rocket Engine- Cost Model (RECM) is an attribute based model developed internally by Pratt & Whitney Rocketdyne for NASA. RECM will be presented primarily to show a successful method to use design and programmatic parameters instead of weight to estimate both design and development costs and production costs. An operations model developed by KSC, the Launch and Landing Effects Ground Operations model (LLEGO), will also be discussed.

We anticipated rational designing of a structure by intrinsic ionic linker could be the solution to produce self-exfoliated CONs without external stimuli. In an attempt to address this issue, we have synthesized three self-exfoliated guanidinium halide based ionic covalent organic nanosheets (iCONs) with antimicrobial property. Self-exfoliation phenomenon has been supported by molecular dynamics (MD) simulation as well. Intrinsic ionic guanidinium unit plays the pivotal role for both self-exfoliation and antibacterial property against both Gram-positive and Gram-negative bacteria. Using such iCONs, we have devised a mixed matrix membrane which could be useful for antimicrobial coatings with plausible medical benefits.

  15. Surgical animal models of neuropathic pain: Pros and Cons.

    One of the biggest challenges for discovering more efficacious drugs for the control of neuropathic pain has been the diversity of chronic pain states in humans. It is now acceptable that different mechanisms contribute to normal physiologic pain, pain arising from tissue damage and pain arising from injury to the nervous system. To study pain transmission, spot novel pain targets and characterize the potential analgesic profile of new chemical entities, numerous experimental animal pain models have been developed that attempt to simulate the many human pain conditions. Among the neuropathic pain models, surgical models have paramount importance in the induction of pain states. Many surgical animal models exist, like the chronic constriction injury (CCI) to the sciatic nerve, partial sciatic nerve ligation (pSNL), spinal nerve ligation (SNL), spared nerve injury (SNI), brachial plexus avulsion (BPA), sciatic nerve transaction (SNT) and sciatic nerve trisection. Most of these models induce responses similar to those found in causalgia, a syndrome of sustained burning pain often seen in the distal extremity after partial peripheral nerve injury in humans. Researchers most commonly use these surgical models in both rats and mice during drug discovery to screen new chemical entities for efficacy in the area of neuropathic pain. However, there is scant literature that provides a comparative discussion of all these surgical models. Each surgical model has its own benefits and limitations. It is very difficult for a researcher to choose a suitable surgical animal model to suit their experimental set-up. Therefore, particular attention has been given in this review to comparatively provide the pros and cons of each model of surgically induced neuropathic pain.

    A total of 104 coagulase negative staphylococci, belonging to S. capitis, S. hominis, S. haemolyticus and S. warneri, originating from the collection of the Department of Pharmaceutical Microbiology (ZMF), Medical University of Lodz, Poland, were tested for their synergistic hemolytic activity. 83% of strains produced δ-hemolysin, however, the percentage of positive strains of S. haemolyticus, S. warneri, S. capitis and S. hominis was different - 98%, 78%, 75% and 68%, respectively. Highly pure hemolysins were obtained from culture supernatants by protein precipitation with ammonium sulphate (0-70% of saturation) and extraction by using a mixture of organic solvents. The purity and molecular mass of hemolysins was determined by TRIS/Tricine PAGE. All CoNS hemolysins were small peptides with a molar mass of about 3.5 kDa; they possessed cytotoxic activity against the line of human foreskin fibroblasts ATCC Hs27 and lysed red cells from different mammalian species, however, the highest activity was observed when guinea pig, dog and human red blood cells were used. The cytotoxic effect on fibroblasts occurred within 30 minutes. The S. cohnii ssp. urealyticus strain was used as a control. The antimicrobial activity was examined using hemolysins of S. capitis, S. hominis, S. cohnii ssp. cohnii and S. cohnii ssp. urealyticus. Hemolysins of the two S. cohnii subspecies did not demonstrate antimicrobial activity. Cytolysins of S. capitis and S. hominis had a very narrow spectrum of action; out of 37 examined strains, the growth of only Micrococcus luteus, Corynebacterium diphtheriae and Pasteurella multocida was inhibited.

    Despite the unique and challenging circumstances confronting Latino migrant worker communities in the U.S., debate still exists as to the need to culturally adapt evidence-based interventions for dissemination with this population. Project Salud adopted a community-based participatory research model and utilized focus group methodology with 83 Latino migrant workers to explore the relevance of culturally adapting an evidence-based HIV prevention intervention to be disseminated within this population. Findings from this study indicate that, despite early reservations, Latino migrant workers wanted to participate in the cultural adaptation that would result in an intervention that was culturally relevant, respectful, responsive to their life experiences, and aligned with their needs. This study contributes to the cultural adaptation/fidelity debate by highlighting the necessity of exploring ways to develop culturally adapted interventions characterized by high cultural relevance without sacrificing high fidelity to the core components that have established efficacy for evidence-based HIV prevention interventions.

    We developed a theory-based dietary change curriculum for Hispanic breast cancer survivors with the goal of testing the effects of the intervention on change in dietary intake of fruits/vegetables and fat in a randomized, clinical trial. Social cognitive theory and the transtheoretical model were used as theoretical frameworks to structure curriculum components using the Nutrition Education DESIGN Procedure. Formative assessments were conducted to identify facilitators and barriers common to Hispanic women and test the degree of difficulty and appropriateness of program materials. Focus groups provided valuable insight and informed preimplementation modifications to the dietary program. The result was a systematically planned, evidence-based, culturally tailored dietary intervention for Hispanic breast cancer survivors, ¡Cocinar Para Su Salud! (Cook for Your Health!). The methodology described here may serve as a framework for the development of future dietary interventions among diverse and minority populations. Short- and long-term study results will be reported elsewhere.

    This article takes stock of how promoting health (PH) (promoción de la salud - PS) has been understood within an international setting and gives three meanings for promotion: as general policy orientation, as a set of actions and as a special dimension of sanitary work. Interest expressed in giving it a specific basis distinguishing it from prevention, transcending educational work, has emerged from the subtle differences established from such different ways of coming to terms with PH. After recognising the challenge posed by PH in the field of health, the text succinctly describes how discourse regarding PH has been introduced in Colombia and discusses how an attempt has been made to be more precise regarding its place in the general health-related social security system. Efforts currently being made in Colombia regarding making PH become a reality within the Colombian health system are then mentioned.

    Introducción: la fibromialgia es una enfermedad crónica caracterizada por dolor crónico general, rigidez, condición física pobre, sueño no reparador y mala calidad de vida relacionada con la salud. Ganoderma lucidum es un tipo de hongo que ha demostrado tener diferentes beneficios en diversas poblaciones. La harina de algarrobo (Ceratonia siliqua) es una fuente natural de antioxidantes con potenciales beneficios para la salud. Objetivo: evaluar los efectos sobre la condición física en mujeres con fibromialgia de un tratamiento de seis semanas con Ganoderma lucidum y compararlos con los de un tratamiento con Ceratonia siliqua. Métodos: sesenta y cuatro mujeres con fibromialgia participaron en el estudio. Se hicieron dos grupos, el primer grupo tomó 6 g diarios de Ganoderma lucidum, mientras que el segundo tomó 6 g diarios de Ceratonia siliqua. Se evaluó la condición física mediante diferentes test físicos validados. Resultados: después de seis semanas de tratamiento, Ganoderma lucidum mejoró significativamente la resistencia aeróbica, la flexibilidad del miembro inferior y la velocidad (p < 0,05). Por otro lado, Ceratonia siliqua no mejoró la condición física. Discusión y conclusiones: Ganoderma lucidum puede mejorar la condición física en mujeres con fibromialgia, mientras que Ceratonia siliqua parece no ser efectivo para este propósito. Estos resultados pueden indicar que 6 g diarios de Ganoderma lucidum podrían ser un suplemento útil para mejorar la condición física en esta población.

    Coagulase-negative staphylococci (CoNS) have become increasingly recognized as important agents of nosocomial infection. One of the characteristics of CoNS is their resistance to multiple antimicrobial agents commonly used for the treatment of staphylococcal infections. CoNS strains (n = 745) isolated from a university teaching hospital in China between 2004 and 2009 were tested for antibiotic resistance. The antibiotics were placed into three categories based on resistance levels of the CoNS strains to these antibiotics: high resistance (resistance rate >70 %), including penicillin G, oxacillin and erythromycin; medium resistance (resistance rate between 30 and 70 %), including tetracycline, clindamycin, ciprofloxacin, trimethoprim/sulfamethoxazole and chloramphenicol; and low resistance (resistance rate <30 %), including rifampicin, ceftizoxime and gentamicin. We also found that the prevalence of strains non-susceptible to teicoplanin increased from 4.5 to 6.7 % between 2008 and 2009. A one-step vancomycin agar selection experiment and subsequent population analysis revealed potentially vancomycin-resistant subpopulations that have been selected from the teicoplanin-non-susceptible strains. Vigilant surveillance of nosocomial isolates of CoNS is needed to determine their resistance to glycopeptides.

This study is aimed at studying the scientific information used in the Revista Española de Salud Pública based on the references cited in the original articles published during the 1991-2000 period. The data regarding the year and where published, document type, language and country in which published was taken from the reference sources listed in the 290 original articles published, the obsolescence, Price and isolation indexes being calculated, and the Bradford core distribution being established according to the source journals. The self-citing rate was also calculated. A total of 7465 references were cited in the Reference section of the 290 original articles. An average of 25.7 references were cited per article. The Price index was 40.7. The scientific articles showed an obsolescence index of 5, the books and book chapters having an index of 6. A total 50.6% of the citations were from studies published in Spanish. The isolation index of the references was 48.1. The first Bradford core is comprised of 10 journals, the first four of which are Spanish. The self-citing rate was 3.8%. The information consumption of the original articles published in the Revista Española de Salud Pública show parameters similar to those of other Spanish health sciences journals for those same years, and the parameters regarding which this Journal differs from other Spanish health sciences journals seem to be justified by those particular aspects unique to public health, which does not fall within the patterns inherent to the clinical disciplines.

    In Mexico, cardiovascular disease and its risk factors are growing problems and major public health concerns. The objective of this study was to implement cardiovascular health promotion and disease prevention activities of the Salud para su Corazón model in a high-risk, impoverished, urban community in Mexico City. We used a pretest-posttest (baseline to 12-week follow-up) design without a control group. Material from Salud para su Corazón was validated and delivered by promotores (community health workers) to community members from 6 geographic areas. Two validated, self-administered questionnaires that assessed participants' knowledge and behaviors relating to heart health were administered. We used t tests and χ(2) tests to evaluate pretest and posttest differences, by age group (≤60 and >60 years), for participants' 3 heart-healthy habits, 3 types of physical activity, performance skills, and anthropometric and clinical measurements. A total of 452 (82%) adult participants completed the program. Heart-healthy habits from pretest to posttest varied by age group. "Taking action" to modify lifestyle behaviors increased among adults aged 60 or younger from 31.5% to 63.0% (P < .001) and among adults older than 60 from 30.0% to 45.0% (P < .001). Positive responses for cholesterol and fat consumption reduction were seen among participants 60 or younger (P = .03). Among those older than 60, salt reduction and weight control increased (P = .008). Mean blood glucose concentration among adults older than 60 decreased postintervention (P = .03). Significant improvements in some heart-healthy habits were seen among adult participants. The model has potential to improve heart-healthy habits and facilitate behavioral change among high-risk adults.

    The high prevalence of cardiovascular disease (CVD) in the Hispanic population of the United States, together with low rates of health insurance coverage, suggest a potential cardiovascular health crisis. The objective of Project HEART (Health Education Awareness Research Team) was to promote behavior changes to decrease CVD risk factors in a high-risk Hispanic border population. Project HEART took place from 2005 through 2008 as a randomized community trial with a community-based participatory research framework using promotores de salud (community health workers). A total of 328 participants with at least 1 CVD risk factor were selected by randomizing 10 US Census tracts in El Paso, Texas, to either the experimental or the control group. The experimental group (n = 192) was assigned to a series of 8 health classes using the Su Corazón, Su Vida curriculum. After 2 months of educational sessions, the group was followed for 2 months. The control group (n = 136) was given basic educational materials at baseline, and no other intervention was used. Main outcomes of interest included changes in health behaviors and clinical measures. Participants in the experimental group showed more awareness of CVD risk factors, more confidence in the control of these factors, and improved dietary habits (ie, lower salt and cholesterol intake, better weight-control practices) compared with the control group. Total cholesterol was 3% lower in the experimental than in the control participants, and nonhigh-density lipoprotein cholesterol and low-density lipoprotein cholesterol were both 5% lower. The HEART trial suggests that community health education using promotores de salud is a viable strategy for CVD risk reduction in a Hispanic border community.

    Convectively-driven strong winds usually associated with thunderstorms frequently cause substantial damage to buildings and other structures in many parts of the world. Decisive for the high damage potential are the short-term wind speed maxima with duration of a few seconds, termed as gusts. Several studies have shown that convectively-driven gusts can reach even higher wind speeds compared to turbulent gusts associated with synoptic-scale weather systems. Due to the small-scale and non-stationary nature of convective wind gusts, there is a considerable lack of knowledge regarding their characteristics and statistics. Furthermore, their interaction with urban structures and their influence on buildings is not yet fully understood. For these two reasons, convective wind events are not included in the present wind load standards of buildings and structures, which so far have been based solely on the characteristics of synoptically-driven wind gusts in the near-surface boundary layer (e. g., DIN EN 1991-1-4:2010-12; ASCE7). However, convective and turbulent gusts differ considerably, e.g. concerning vertical wind-speed profiles, gust factors (i.e., maximum to mean wind speed), or exceedance probability curves. In an effort to remedy this situation, the overarching objective of the DFG-project "Convective Wind Gusts" (ConWinG) is to investigate the characteristics and statistics of convective gusts as well as their interaction with urban structures. Based on a set of 110 climate stations of the German Weather Service (DWD) between 1992 and 2014, we analyzed the temporal and spatial distribution, intensity, and occurrence probability of convective gusts. Similar to thunderstorm activity, the frequency of convective gusts decreases gradually from South to North Germany. A relation between gust intensity/probability to orography or climate conditions cannot be identified. Rather, high wind speeds, e.g., above 30 m/s, can be expected everywhere in Germany with almost

    Covalent organic nanosheets (CONs) have emerged as a new class of functional two-dimensional (2D) porous organic polymeric materials with a high accessible surface, diverse functionality, and chemical stability. They could become versatile candidates for targeted drug delivery. Despite their many advantages, there are limitations to their use for target specific drug delivery. We anticipated that these drawbacks could be overturned by judicious postsynthetic modification steps to use CONs for targeted drug delivery. The postsynthetic modification would not only produce the desired functionality, it would also help to exfoliate to CONs as well. In order to meet this requirement, we have developed a facile, salt-mediated synthesis of covalent organic frameworks (COFs) in the presence of p-toluenesulfonic acid (PTSA). The COFs were subjected to sequential postsynthetic modifications to yield functionalized targeted CONs for targeted delivery of 5-fluorouracil to breast cancer cells. This postsynthetic modification resulted in simultaneous chemical delamination and functionalization to targeted CONs. Targeted CONs showed sustained release of the drug to the cancer cells through receptor-mediated endocytosis, which led to cancer cell death via apoptosis. Considering the easy and facile COF synthesis, functionality based postsynthetic modifications, and chemical delamination to CONs for potential advantageous targeted drug delivery, this process can have a significant impact in biomedical applications.

  11. Analyses of muscular dystrophy and Con A deficiency traits in testcross progeny of chickens.

    Hereditary muscular dystrophic chickens of the Storrs strain possess two genetic disorders, muscular dystrophy (MD) and a deficient concanavalin A (Con A), a T-cell mitogen, mediated splenic lymphocyte blastogenic response. A possible amelioration of the MD phenotype in MD chickens expressing normal Con A was postulated on the basis of progeny segregating for these two traits in F2 genetic analyses. To test this possibility, testcross progeny were examined for segregation of MD and Con A deficiency traits, and for the degree of muscle destruction and Con A deficiency. The data show both traits to be inherited independently as autosomal recessive traits, and do not support any phenotypic modifications occurring in chickens expressing MD with normal Con A. In the testcross progeny, the Con A deficiency disorder is equally deficient in normal and MD progeny, and the degree of muscle destruction as measured by serum creatine phosphokinase levels is equally great in MD chickens with or without the Con A deficiency trait. The reduced numbers of MD chickens in the testcross progeny can be accounted for by chance and probably reflect losses during in ovo development.

    ConO- (n = 1-3) clusters were investigated with photoelectron spectroscopy and density functional calculations. The vertical detachment energies (VDEs) of ConO- (n = 1-3) were measured to be 1.54 ± 0.04, 1.43 ± 0.08, and 1.42 ± 0.08 eV respectively from their photoelectron spectra. The electron affinity and term energy of CoO were determined to be 1.54 ± 0.04 eV and 0.31 ± 0.04 eV respectively based on the vibrationally resolved photoelectron spectrum of CoO- and theoretical calculations. The structures of ConO- (n = 1-3) were determined by comparison of photoelectron experiments and calculations. The analysis of molecular orbitals shows that the HOMOs of ConO- (n = 1-3) cluster anions are mainly localized on the Co atoms.

    Reliable assessment of in situ pathology analyses like immunohistochemistry, RNA in situ hybridization, and FISH are critically important in diagnosis and treatment decisions. We describe the development of small tissue microarrays (TMA) for the internal control and quantitation of these techniques, the iCon-TMA. In its simple variant, these iCon-TMA (abbreviated from internal control TMA) consist of 2 tissue cylinders, one being clearly positive and the other clearly negative for a specific marker. In its more elaborate format, the iCon-TMAs carry additional tissue spots providing a scale for quantitatively assessable markers, e.g. representing scores of negative, weak, moderate, or strong positivity. The specimen with the yet unknown reactivity is then applied to the iCon-TMA section, and both are simultaneously processed and analyzed, thus providing a convenient measure for in situ quality control and quantitation.

Epstein and M. G. Plys, Fauske & Associates, LLC, June 2009. The Sludge Treatment Project (STP) will retrieve sludge from the 105-K West Integrated Water Treatment System (IWTS) Settler Tanks and transfer it to container SCS-CON-230 using the Settler Tank Retrieval System (STRS). The sludge will enter the container through two distributors. The container will have a filtration system that is designed to minimize the overflow of sludge fines from the container to the basin. FAI/09-91 was performed to quantify the effect of the STRS on sludge distribution inside of and overflow out of SCS-CON-230. Selected results of the analysis and a system description are discussed. The principal result of the analysis is that the STRS filtration system reduces the overflow of sludge from SCS-CON-230 to the basin by roughly a factor of 10. Some turbidity can be expected in the center bay where the container is located. The exact amount of overflow and subsequent turbidity is dependent on the density of the sludge (which will vary with location in the Settler Tanks) and the thermal gradient between the SCS-CON-230 and the basin. Attachment A presents the full analytical results. These results are applicable specifically to SCS-CON-230 and the STRS filtration system's expected operating duty cycles.

      Sport concussion is currently the focus of much international attention. Innovative methods to assist athletic trainers in facilitating management after this injury need to be investigated.   To investigate the feasibility of using a Facebook concussion-management program termed iCon (interactive concussion management) to facilitate the safe return to play (RTP) of young persons after sport concussion.   Observational study.   Facebook group containing interactive elements, with moderation and support from trained health care professionals.   Eleven participants (n = 9 men, n = 2 women; range, 18 to 28 years old) completed the study.   The study was conducted over a 3-month period, with participant questionnaires administered preintervention and postintervention. The primary focus was on the qualitative experiences of the participants and the effect of iCon on their RTP. Usage data were also collected.   At the completion of the study, all participants (100%) stated that they would recommend an intervention such as iCon to others. Their supporting quotes all indicated that iCon has the potential to improve the management of concussion among this cohort. Most participants (n = 9, 82%) stated they were better informed with regard to their RTP due to participating in iCon.   This interactive adjunct to traditional concussion management was appreciated among this participant group, which indicates the feasibility of a future, larger study of iCon. Athletic trainers should consider the role that multimedia technologies may play in assisting with the management of sport concussion.

    Among Hispanic breast cancer survivors, we examined the long-term effects of a short-term culturally based dietary intervention on increasing fruits/vegetables (F/V), decreasing fat, and changing biomarkers associated with breast cancer recurrence risk. Spanish-speaking women (n = 70) with a history of stage 0-III breast cancer who completed treatment were randomized to ¡Cocinar Para Su Salud! (n = 34), a culturally based 9-session program (24 hours over 12 weeks, including nutrition education, cooking classes, and food-shopping field trips), or a control group (n = 36, written dietary recommendations for breast cancer survivors). Diet recalls, fasting blood, and anthropometric measures were collected at baseline, 6, and 12 months. We report changes between groups at 12 months in dietary intake and biomarkers using 2-sample Wilcoxon t tests and generalized estimating equation (GEE) models. At 12 months, the intervention group compared with the control group reported higher increases in mean daily F/V servings (total: +2.0 vs. -0.4; P < 0.01), and nonsignificant decreases in the percentage of calories from fat (-2.2% vs. -1.1%; P = 0.69) and weight (-2.6 kg vs. -1.5 kg; P = 0.56). Compared with controls, participants in the intervention group had higher increases in plasma lutein (+20.4% vs. -11.5%; P < 0.01), and borderline significant increases in global DNA methylation (+0.8% vs. -0.5%; P = 0.06). The short-term ¡Cocinar Para Su Salud! program was effective at increasing long-term F/V intake in Hispanic breast cancer survivors and changed biomarkers associated with breast cancer recurrence risk. It is possible for short-term behavioral interventions to have long-term effects on behaviors and biomarkers in minority cancer patient populations. Results can inform future study designs.

    Marijuana use on college campuses is prevalent and associated with high rates of abuse and dependence. The Marijuana Decisional Balance (MDB) scales measure perceived pros and cons toward marijuana use. Evidence supports reliability and concurrent validity of these scales, but the predictive validity has not yet been assessed. The current study evaluated the prospective predictive validity of pros and cons scales for marijuana use, as well as explored predictive validity for marijuana problem indicators. Secondary analyses included test-retest reliability and internal consistency, to provide additional evidence of psychometric properties. A total of 149 college students (57% recent marijuana users, 77% lifetime users) participated in a baseline survey, then completed a second survey one month later. All provided data on marijuana pros and cons, as well as use status in the past month. Users at each time point reported on use frequency, problems, and disorder symptoms. In the month between assessments, 55% of the students used marijuana. Both pros and cons subscales prospectively predicted use status in the subsequent month, but not use frequency. Pros prospectively predicted marijuana problems and dependence symptoms at follow-up, and remained a significant predictor of later dependence symptoms even after controlling for baseline dependence symptoms. In contrast, pros only marginally predicted abuse. Cons did not predict problems, abuse, or dependence symptoms. Pros and cons showed strong test-retest reliability (rs = 0.80-0.85) and internal consistency (alphas = 0.92-0.95). In a college sample, pros and cons of marijuana use demonstrated stability over one month, and prospectively predicted use. Pros may also have utility in predicting problems and dependence potential on college campuses.

    La investigacion---accion que se llevo a cabo en la sala de clases tenia como punto de partida las creencias de la cultura de la ciencia de un grupo de estudiantes universitarios para luego examinar sus implicaciones en el proceso de aprendizaje de las Ciencias Biologicas. ¿Que se supone que hagan las creencias en relacion con el aprendizaje? ¿En que consiste incorporar este aspecto a la practica educativa universitaria? Utilizando el modelo de Kemmis y McTaggart (1987) la investigacion-accion se planteo como un proceso dinamico en cuatro momentos en espiral constituidos por la planificacion, la accion, la observacion y la reflexion. Cada una de las fases tuvo una intencion retrospectiva y prospectiva formando una espiral de autorreflexion del conocimiento y la accion. Se llevaron a cabo audio grabaciones en clases y analisis de documentos. Ademas, la profesora-investigadora hizo un portafolio para reflexionar sobre las creencias de la cultura de la ciencia que tienen los estudiantes y las creencias del aprendizaje que tiene la profesora y sobre como la comprension de estos elementos ayudo a mejorar su practica educativa a traves del tiempo. Los resultados obtenidos apuntan a que las creencias de la cultura de la ciencia que tiene el grupo de estudiantes son diversas. Ellos si creen que la ciencia tiene una cultura la cual describieron como: complicada y desconocida que evoluciona constantemente, que es un conjunto de metodos, que es altamente tecnologica, que resuelve problemas de salud, ayuda a interpretar la realidad del mundo que los rodea y su origen y que existen unas intersecciones entre la ciencia y el poder. Sobre las creencias del proceso de aprendizaje de la profesora-investigadora, estas senalan que el modelaje de actores, la vision de la academia que tiene ella asi como la participacion y negociacion entre todos los involucrados en el proceso educativo, son factores que inciden en el proceso de aprendizaje.

    Knowledge of the correct protein subcellular localization is necessary for understanding the function of a protein. Unfortunately large-scale experimental studies are limited in their accuracy. Therefore, the development of prediction methods has been limited by the amount of accurate experimental data. However, recently large-scale experimental studies have provided new data that can be used to evaluate the accuracy of subcellular predictions in human cells. Using this data we examined the performance of state of the art methods and developed SubCons, an ensemble method that combines four predictors using a Random Forest classifier. SubCons outperforms earlier methods in a dataset of proteins where two independent methods confirm the subcellular localization. Given nine subcellular localizations, SubCons achieves an F1-Score of 0.79 compared to 0.70 of the second best method. Furthermore, at a FPR of 1% the true positive rate (TPR) is over 58% for SubCons compared to less than 50% for the best individual predictor. SubCons is freely available as a webserver (http://subcons.bioinfo.se) and source code from https://bitbucket.org/salvatore_marco/subcons-web-server. The golden dataset as well is available from http://subcons.bioinfo.se/pred/download. arne@bioinfo.se. Supplementary data are available at Bioinformatics online.

    Fluorescent glucose sensing technologies have been identified as possible alternatives to current continuous glucose monitoring approaches. We have recently introduced a new, smart fluorescent ligand to overcome the traditional problems of ConA-based glucose sensors. For this assay to be translated into a continuous glucose monitoring device where both components are free in solution, the molecular weight of the smart fluorescent ligand must be increased. We have identified ovalbumin as a naturally-occurring glycoprotein that could serve as the core-component of a 2nd generation smart fluorescent ligand. It has a single asparagine residue that is capable of displaying an N-linked glycan and a similar isoelectric point to ConA. Thus, binding between ConA and ovalbumin can potentially be monovalent and sugar specific. This work is the preliminary implementation of fluorescently-labeled ovalbumin in the ConA-based assay. We conjugate the red-emitting, long-lifetime azadioxatriangulenium (ADOTA+) dye to ovalbumin, as ADOTA have many advantageous properties to track the equilibrium binding of the assay. The ADOTA-labeled ovalbumin is paired with Alexa Fluor 647-labeled ConA to create a Förster Resonance Energy Transfer (FRET) assay that is glucose dependent. The assay responds across the physiologically relevant glucose range (0-500 mg/dL) with increasing intensity from the ADOTA-ovalbumin, showing that the strategy may allow for the translation of the smart fluorescent ligand concept into a continuous glucose monitoring device.

    The rapidly growing number of available prokaryotic genome sequences requires fully automated and high-quality software solutions for their initial and re-annotation. Here we present ConsPred, a prokaryotic genome annotation framework that performs intrinsic gene predictions, homology searches, predictions of non-coding genes as well as CRISPR repeats and integrates all evidence into a consensus annotation. ConsPred achieves comprehensive, high-quality annotations based on rules and priorities, similar to decision-making in manual curation and avoids conflicting predictions. Parameters controlling the annotation process are configurable by the user. ConsPred has been used in the institutions of the authors for longer than 5 years and can easily be extended and adapted to specific needs. The ConsPred algorithm for producing a consensus from the varying scores of multiple gene prediction programs approaches manual curation in accuracy. Its rule-based approach for choosing final predictions avoids overriding previous manual curations. ConsPred is implemented in Java, Perl and Shell and is freely available under the Creative Commons license as a stand-alone in-house pipeline or as an Amazon Machine Image for cloud computing, see https://sourceforge.net/projects/conspred/. thomas.rattei@univie.ac.atSupplementary information: Supplementary data are available at Bioinformatics online. © The Author 2016.

    En el marco de un proyecto de investigación-acción que se implementó en Venezuela de 2009 a 2013 se buscó empoderar (empower) a activistas sociales y pacientes en la lucha contra el cáncer de mama (CM). Este proyecto se puso en marcha en un contexto de alta polarización política y social en el marco de la llamada «Revolución bolivariana». A partir de una perspectiva ecológica de la comunicación y el activismo en salud, que integra los niveles interpersonal, grupal y social, se celebraron una serie de actividades orientadas a desarrollar las habilidades de vocería de ciudadanos, especialmente de mujeres, y ampliar las redes de cooperación entre diversos sectores, al mismo tiempo que se perfiló una visión consensuada entre actores sociales e institucionales sobre una respuesta nacional contra el CM. Una comunicación horizontal y participativa permitió que se escuchara la voz de actores usualmente marginalizados en las políticas sanitarias. PMID:27867911

    Hypertension is a growing public health problem for U.S.-Mexico border Latinos, who commonly experience low levels of awareness, treatment, and control. We report on a process evaluation that assessed the delivery of Corazón por la Vida, a 9-week promotora de salud-led curriculum to help Latinos manage and reduce hypertension risks in two rural/frontier counties in the New Mexico border region. Ninety-six adults participated in the program, delivered in three waves and in three communities. We assessed program delivery and quality, adherence, exposure, and participant responsiveness. Participant outcome measures included self-reported eating and physical activities and assessment of community resources. Findings suggest that the program was fully delivered (99%) and that most participants (81.7%) were very satisfied with the educational sessions. The average participant attendance for educational sessions was 77.47%. We found significant differences in self-reported behavioral changes depending on the number of sessions completed: The higher the dose of sessions, the better the self-reported outcomes. These findings suggest that a promotora-led curriculum may be useful for promoting self-management of chronic disease in rural/frontier border Latino populations. Future evaluation should focus on training and implementation adaptations within evidence-based chronic disease programs for diverse Latino communities.

    Health care discrimination is increasingly considered a significant barrier to accessing health services among minority populations, including Latinos. However, little is known about the role of immigration status. The purpose of this study was to examine the association between immigration status and perceived health care discrimination among Latinos living in rural areas. Interviews were conducted among 349 young-adult Latinos (ages 18 to 25) living in rural Oregon, as part of Proyecto de Salud para Latinos. Over a third of participants experienced health care discrimination (39.5 %). Discrimination was higher among foreign-born (44.9 %) rather than US-born Latinos (31.9 %). Multivariate results showed that foreign-born Latinos were significantly more likely to experience health care discrimination, even after controlling for other relevant factors (OR = 2.10, 95 % CI 1.16-3.82). This study provides evidence that health care discrimination is prevalent among young-adult Latinos living in rural areas, particularly the foreign-born. Effective approaches towards reducing discrimination in health care settings should take into consideration the need to reform our broken immigration system.

    The development of scientific health research requires a sustained and articulated research system that is consistent with the research priorities, as well as both internal and external funding, and availability of competent human resources. The Mining Canon, a constitutional right, has been partly used to foster applied scientific research in public universities (PU). In addition, the National Health Institute (INSTITUTO NACIONAL DE SALUD - INS) is devoted, among others, to promoting, managing and disseminating health research development at a national level. As part of these activities, a technical team was created to provide technical assistance to PU for research development using Mining Canon funds by making local adjustments to research protocols promoted by the INS and assumed by the professors-researchers at the Universities. This article aims at describing the reality of research at Peruvian public universities that have access to Mining Canon funds, as well as to elaborate on the work the INS is carrying out in order to strengthen research capabilities, starting with the development of research proposals that could potentially be funded by the Mining Canon.

    The evaluation for Celebremos La Salud, a community randomized trial of Hispanic cancer prevention found no differences in mammography screening rates between intervention and control communities. The goal of the present study was to determine reasons for the intervention's lack of effectiveness. In the first aim, we assessed reach of the intervention. In the second, we assessed which intervention activities were associated with mammography use. In the third, we examined whether factors related to health care access, education level, or age modified the effect of the intervention. Data were used from a post-intervention survey of 20 rural communities in Washington State. Hispanic (N = 202) and non-Hispanic White (N = 389) women, over age 40 formed the sample. Reporting having awareness of or having participated in intervention activities was positively associated with Hispanic ethnicity and intervention group and negatively associated with lack of health insurance and having a lower education level. Only one intervention activity was associated with screening use. Having participated in presentations at organizations was positively associated with having had a mammogram in the previous 2 years for Hispanic women. No individual level modifiers influenced the intervention's effectiveness. Heavily targeting the intervention to Hispanic women and not reaching as many White women may have contributed to the lack of intervention effect. Increasing mammography screening rates among women living in a rural area may require improved access to health care and reaching women with lower education levels and lack of health insurance.

    Manipulating Mycobacterium tuberculosis clinical specimens and cultures represents a risk factor for laboratory personnel. One of the processes that requires high concentrations of microorganisms is DNA extraction for molecular procedures. Pulmonary tuberculosis cases have occurred among professionals in charge of molecular procedures that require manipulation of massive quantities of microorganisms. This has prompted research studies on biosafety aspects of extraction protocols; however, as yet, no consensus has been reached regarding risks associated with the process. The biosafety was evaluated for the DNA extraction protocol of van Soolingen, et al. 2002 by determining M. tuberculosis viability at each process stage. Eight hundred eighty cultures were grown from 220 M. tuberculosis clinical isolates that had been processed through the first three DNA extraction stages. Molecular identifications of positive cultures used a PCR isolation of a fragment of the heat shock protein PRA-hsp65 and examination of its restriction enzyme profile (spoligotyping). Growth was seen in one culture with one of the procedures used. The molecular characterization did not correspond to the initially analyzed isolate, and therefore was deduced to be the product of a cross-contamination. The DNA extraction protocol, as described by van Soolingen, et al. 2002 and as implemented at the Instituto Nacional de Salud, was established to be safe for laboratory personnel as well as for the environment.

    Entre Familia: Reflejos de Salud was a successful family-based randomized controlled trial designed to improve dietary behaviors and intake among U.S. Latino families, specifically fruit and vegetable intake. The novel intervention design merged a community health worker (promotora) model with an entertainment-education component. This process evaluation examined intervention implementation and assessed relationships between implementation factors and dietary change. Participants included 180 mothers randomized to an intervention condition. Process evaluation measures were obtained from participant interviews and promotora notes and included fidelity, dose delivered (i.e., minutes of promotora in-person contact with families, number of promotora home visits), and dose received (i.e., participant use of and satisfaction with intervention materials). Outcome variables included changes in vegetable intake and the use of behavioral strategies to increase dietary fiber and decrease dietary fat intake. Participant satisfaction was high, and fidelity was achieved; 87.5% of families received the planned number of promotora home visits. In the multivariable model, satisfaction with intervention materials predicted more frequent use of strategies to increase dietary fiber (p ≤ .01). Trends suggested that keeping families in the prescribed intervention timeline and obtaining support from other social network members through sharing of program materials may improve changes. Study findings elucidate the relationship between specific intervention processes and dietary changes. © 2015 Society for Public Health Education.

    Large scale data analysis is nowadays a crucial part of drug discovery. Biologists and chemists need to quickly explore and evaluate potentially effective yet safe compounds based on many datasets that are in relationship with each other. However, there is a lack of tools that support them in these processes. To remedy this, we developed ConTour, an interactive visual analytics technique that enables the exploration of these complex, multi-relational datasets. At its core ConTour lists all items of each dataset in a column. Relationships between the columns are revealed through interaction: selecting one or multiple items in one column highlights and re-sorts the items in other columns. Filters based on relationships enable drilling down into the large data space. To identify interesting items in the first place, ConTour employs advanced sorting strategies, including strategies based on connectivity strength and uniqueness, as well as sorting based on item attributes. ConTour also introduces interactive nesting of columns, a powerful method to show the related items of a child column for each item in the parent column. Within the columns, ConTour shows rich attribute data about the items as well as information about the connection strengths to other datasets. Finally, ConTour provides a number of detail views, which can show items from multiple datasets and their associated data at the same time. We demonstrate the utility of our system in case studies conducted with a team of chemical biologists, who investigate the effects of chemical compounds on cells and need to understand the underlying mechanisms.

    Diagnosis and quantification of Echinococcus granulosus infection in man and animal hosts are centralized to feasible control. This study included 93 serum samples, 25 sure positive hydatid cases confirmed surgically, 7 suspected cases diagnosed by indirect haemagglutination IHA and 41 cases other parasitic infections (15 S. mansoni, 8 Fasciola, 7 Ascaris, 5 H. nana & 6 Ancylostoma) diagnosed by microscopic examination and were negative by ELISA and/or IHA for anti-hydatid antibody. Twenty negative serum samples served as healthy controls. Six types of hydatid fluid antigens (crude, host-free & Con-A purified) of human and camel origin were subjected to electrophoretic separation (SDS-PAGE) and immunoblotting (EITB). The anti-hydatid IgG was detected in sera of the different groups for evaluation of sensitivity, specificity and diagnostic efficacy of each type of antigens. Detection of circulating hydatid antigen (CAg) was performed using anti rabbit hyperimmune sera raised against Con-A purified either human or camel hydatid antigen. SDS-PAGE revealed several bands ranging from 55-185 kDa with 10 kDa band shared by all antigens. The specific bands revealed by EITB for Con-A purified camel and human antigens were at 80, 110 & 55, 110 kDa respectively. ELISA highest sensitivity (96.9%) was by using host-free Con-A purified glycoprotein fraction of human hydatid antigen. Highest specificity (98.4%) was recorded upon use of either Con-A purified camel or human antigen with 94.5% & 97.7% diagnostic efficacy respectively. Detection of circulating antigen by polyclonal antibodies against Con-A purified human hydatid antigen revealed 91.8% specificity.

    To maintain certification by the American Board of Emergency Medicine (ABEM), physicians are required to pass the Continuous Certification (ConCert) examination at least every 10 years. On the 2014 ConCert postexamination survey, ABEM sought to understand the manner in which ABEM diplomates prepared for the test and to identify associations between test preparation approaches and performance on the ConCert examination. This was a cross-sectional survey study. The survey was administered at the end of the 2014 ConCert examination. Analyses included chi-square and linear regression to determine the association of preparation methods with performance. Of the 2,431 on-time test-takers, 2,338 (96.2%) were included. The most commonly used study approach was the review of written materials designed for test preparation (1,585; 67.8%), followed by an online training course (1,006; 43.0%). There were 758 (32.4%) physicians who took a single onsite board review course, while 41 (1.8%) took two or more onsite courses. Most physicians (1,611; 68.9%) spent over 35 hours preparing for the ConCert examination. The study method that was most associated with favorable test scores was the review of written materials designed for test preparation (p < 0.001). Attending an onsite preparation course was associated with poorer performance (p < 0.001). There was a significant association between no additional preparation and failing the examination (chi-square with Yates correction; p = 0.001). A substantial majority (97.8%) of physicians taking the 2014 ABEM ConCert examination prepared for it. The majority of physicians used written materials specifically designed for test preparation. Reviewing written materials designed for test preparation was associated with the highest performance. © 2016 by the Society for Academic Emergency Medicine.

El metodo se basa en consideraciones sencillas de conservacion de momento para las superficies de trabajo que se forman en el interior del jet. Como ejemplo, se presentan soluciones para jets con variacion sinusoidal en la velocidad de eyeccion, y tambien para el caso de un incremento lineal en el tiempo. Estas soluciones analiticas tienen una clara aplicacion en la interpretacion de las observaciones de jets asociados a objetos Herbig-Haro.

  19. Reversible hydrogen adsorption on Co/N4 cluster embedded in graphene: The role of charge manipulation

    NASA Astrophysics Data System (ADS)

    Omidvar, Akbar

    2017-08-01

    Electrical charging of Co/N4 cluster embedded in graphene (Co/N4/G) is proposed as an approach for electrocatalytically switchable hydrogen adsorption. Using density functional theory, we found that the H2 molecule is weakly adsorbed on the uncharged Co/N4/G cluster. Our results show that the adsorption energy of hydrogen molecule on Co/N4/G cluster is significantly increased by introducing extra positive charges into the cluster. Once the charges are removed, H2 molecule spontaneously desorb from the Co/N4/G absorbent. Therefore, this approach promises both facile reversibility and tunable kinetics without the need of specific catalysts. Our study indicates that the Co/N4/G nanomaterial is excellent absorbent for controllable and reversible adsorption and release of H2.

    La obesidad es una enfermedad muy prevalente con múltiples complicaciones crónicas que se reducen o desaparecen tras pérdidas pequeñas (5-10%) pero mantenidas de peso. Sin embargo, mantener la pérdida de peso tras el tratamiento es muy difícil, siendo uno de los mayores retos en el control de esta enfermedad. Aunque las razones que contribuyen a recuperar el peso perdido son de diversa índole, relacionadas con la respuesta biológica a la restricción calórica y con la pérdida de adherencia al tratamiento, hasta un 20% de los pacientes son capaces de mantenerlo. Las claves del éxito están relacionadas con el mantenimiento de los hábitos de vida saludable, el ejercicio físico y una ingesta calórica razonable que permita realizar una vida normal, sin pérdida de vida social. En este sentido, aprender a distinguir las opciones de comida y bebida en una sociedad donde la vida social gira en torno a la mesa en muchas ocasiones es muy importante. Revisamos en este artículo las claves para mantener el peso tras una dieta, así como el papel de las bebidas fermentadas, en especial, la cerveza, en este proceso. En conclusión, mantener el peso perdido es más difícil que perderlo. El consumo leve-moderado de bebidas fermentadas como la cerveza no se asocia con incremento del peso.

    Introduccion. Los problemas en la correcta adquisicion del lenguaje se han estudiado mucho, pero con escasas conclusiones globales; a ello contribuye la variabilidad individual, la existencia de diferentes medidas para evaluar el lenguaje y a que en su desarrollo participa una compleja red de factores geneticos y ambientales. Objetivo. Revisar las variables ambientales y geneticas que se han investigado hasta la actualidad, para comprender mejor las causas de los trastornos especificos del lenguaje y crear nuevas evidencias que faciliten la elaboracion de sistemas de deteccion precoz de estos trastornos. Desarrollo. Dentro de las variables ambientales relacionadas con peor desarrollo en el lenguaje infantil estan el sexo masculino, un nivel educacional maternal bajo, una historia familiar de problemas en el lenguaje o problemas psiquiatricos, los problemas perinatales y los problemas de salud en la infancia. El bilinguismo parece ser un factor protector. El temperamento y el lenguaje tienen relacion. Dentro de los factores geneticos existen ya varios genes especificos asociados con el lenguaje, dos de ellos con una influencia mayor en su adquisicion fisiologica: FOXP2 y CNTNAP2. Los otros genes mas relacionados con trastornos especificos del lenguaje son ATP2C2, CMIP, ROBO2, ZNF277 y NOP9. Conclusiones. La clave para entender el desarrollo de los trastornos especificos del lenguaje radica en llegar a comprender el verdadero papel que desempeñan los genes en la ontogenia, regulando los diferentes procesos de desarrollo y como este papel se ve modulado por el ambiente.

  2. Quantifying Hydrological Ecosystem Services of Various Land Covers and Uses on Small Experimental Catchments within the Panama Canal Watershed: The Agua Salud Project

    As a part of the Agua Salud Project, a baseline characterization of hydrologic processes on the small catchment scale (~0.24 to 2.0 km2) is assessed across different land uses and covers typical to rural Panama. The land covers being monitored include a mature secondary forest, a disturbed catchment with a mosaic of various aged secondary growth and agricultural use, an active pasture and a monoculture invasive grass site as experimental controls, and two treated catchments that were recently abandoned pastures converted to teak and native species timber plantations. The catchments are found within Panama's protected Soberania National Park and the adjacent headwaters of the Agua Salud and Mendoza Rivers, all part of the greater Panama Canal Watershed. Using hydrological data from the first two and a half years of the project, three main ecosystem services are observed. The forested area exhibited lower storm event peaks, decreased flashiness, and greater stream flow during the dry season compared to the disturbed mosaic site. Lower hydrograph peaks and flashiness mitigate the risk of substantial flood damage during the major flood events generally seen in Panama between October and December. The mature forest (1.35 km2) catchment has shown lower average flood peaks in comparison to the disturbed site. For storm peaks less than 6 mm/hr, flood peaks are on average 51% lower. For storm peaks greater than 6 mm/hr, flood peaks are approximately 40% lower. In 1998, draft restrictions were imposed in the Panama Canal because of a deficit of dry season water after an El Niño-Southern Oscillation resulted in decreased wet season rainfall. The water that is available during the end of the dry season has the potential to insure the full operation of the Canal during El Niño drought years. Toward the end of the dry season (March through May) our data shows that roughly 34% more water was available during a relatively dry year with respect to antecedent wet season rainfall

    This article presents results from an evaluation of the ConRed cyberbullying intervention program. The program's impacts were separately determined for the different roles within cyberbullying that students can take, i.e., cyber-victims, cyber-bullies, cyber-bully/victims, and bystanders. The ConRed program is a theory-driven program designed to prevent cyberbullying and improve cyberbullying coping skills. It involves students, teachers, and families. During a 3-month period, external experts conducted eight training sessions with students, two with teachers and one with families. ConRed was evaluated through a quasi-experimental design, in which students from three secondary schools were separated into experimental and control groups. The sample comprised 875 students, aged between 11 and 19 years. More students (n = 586) were allocated to the experimental groups at the specific insistence of the management of all schools; the remainder (n = 289) formed the control. Repeated measures MANOVA showed that cyber victims, cyber aggressors and cyberbully/victims reduced their involvement in cyberbullying. Moreover, cyber-victims and bystanders adjusted their perceptions about their control of personal information on the Internet, and cyber aggressors and bystanders reduced their Internet dependence. The ConRed program had stronger effects on male participants, especially in heightening their affective empathy. © 2015 Wiley Periodicals, Inc.

    We are undertaking a 1000 hour campaign with the Karl G. Jansky VLA to survey 0.2 square degrees of the COSMOS field in full polarization continuum at 1.4 GHz. Our observations are part of a joint program with the spectral line COSMOS HI Large Extragalactic Survey (CHILES). When complete, we expect our CHILES Continuum Polarization (CHILES Con Pol) survey to reach an SKA-era sensitivity of 500 nJy per 4 arcsecond resolving beam, the deepest view of the radio sky yet. CHILES Con Pol will open new and fertile parameter space, with sensitivity to star formation rates of 10 Msun per year out to an unprecedented redshift of z=2, and ultra-luminous infrared galaxies and sub-millimeter galaxies out to redshifts of z=8 and beyond. This rich resource will extend the utility of radio band studies beyond the usual radio quasar and radio galaxy populations, opening sensitivity to the starforming and radio-quiet AGN populations that form the bulk of extragalactic sources detected in the optical, X-ray, and infrared bands. In this talk I will outline the key science of CHILES Con Pol, including galaxy evolution and novel measurements of intergalactic magnetic fields. I will present initial results from the first 180 hours of the survey and describe our forthcoming Data Release 1. I invite the astronomical community to consider unique science that can be pursued with CHILES Con Pol radio data.

    A high prevalence of physical inactivity, metabolic risk factors, and depression place Latinas in peril of developing cardiovascular disease. "Un Corazón Saludable: A Healthy Heart" was developed to engage urban Latinas in physical activity and increase awareness of cardiac and metabolic risk factors. Two hundred and twenty-five Latinas enrolled in the program that included salsa aerobics and culturally sensitive health education modules. Cardiac and metabolic risk factors measured in this study were body mass index (BMI), waist-to-hip ratio, abdominal obesity, and blood pressure. Psychosocial risk factors measured included depressive symptoms and perceived social support. Fifty-two percent of the enrollees completed the program. Results indicated decreases in BMI, abdominal obesity, and symptoms of depression among Latinas who completed the program. Those who did not complete the program were younger, had greater depressive symptomatology, reported poorer social support, and they tended to be caregivers and U.S. born. Focus groups of program participants ascertained that caregiving and family obligations were major barriers to exercise while social support was a major facilitator of exercise. This research indicates that programs developed to recognize and address cultural barriers can impact physical and psychosocial risk factors among urban Latinas who are able to attend. Program retention may improve if future exercise programs conducted through community-base organizations offered support to Latinas regarding issues that interfere with self-care and health promotion. Future programs should consider including mental health and social service case management as part of comprehensive exercise/educational programs.

    The hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PPHN) are distinct pulmonary vascular complications of portal hypertension (PHT) and are associated with increased morbidity and mortality. To describe the clinical and laboratory characteristics of patients with pulmonary hypertension and pulmonary vascular complications hospitalized at the Instituto Nacional de Salud del Niño. We included patients with HTP hospitalized from January 2012 to June 2013 and that during its evolution progressed with SHP or HTPP. For analysis, they were divided into a first group of patients with liver cirrhosis and a second group with extrahepatic portal vein obstruction. Of 22 patients with HPT 45.5% were male and the age range was between 1 month and 17 years. The etiology in the group of cirrhosis (n=14) was: autoimmune hepatitis (35.7%), cryptogenic cirrhosis (35.7%), inborn error of metabolism (14.3%), chronic viral hepatitis C (7.15%) virus and atresia extra-hepatic bile ducts (7.15%). Pulmonary vascular complications more frequently occurred in patients with liver cirrhosis (1 case of HPS and a case of PPHTN). They most often dyspnea, asthenia, edema, malnutrition, ascites, hypersplenism and gastrointestinal bleeding from esophageal varices was found. Also, they had elevated ALT values, alkaline phosphatase and serum albumin values decreased. In children with pulmonary hypertension, pulmonary vascular complications are rare. In the evaluation of these patients pulse oximetry should be included to detect hypoxemia and ubsequently a Doppler echocardiography and contrast echocardiography necessary. Dueto the finding of systolic pulmonary hypertension it is necessary to perform right heart catheterization.

    To evaluate a community-wide campaign, Tu Salud ¡Si Cuenta! (TSSC), in improving eating behaviors and anthropometric outcomes in Hispanic border communities. A quasi-experimental study with matched intervention and comparison communities. Cross-sectional assessments with randomly sampled adults, examined by actual exposure and site (unexposed intervention, exposed intervention, and unexposed comparison). Predominately Mexican Americans located in Brownsville, TX (intervention) and Laredo, TX (control). The TSSC campaign included television and radio segments, community health worker discussions, and newsletters delivered in Brownsville from 2005 to 2010. Healthy and unhealthy eating indices and average hip and waist circumferences. Univariable and multivariable regression models. The sample (n = 799; 400 comparison and 399 intervention) was 98% of Mexican origin; 54% had completed grade 9 or higher. Exposure to any TSSC component was associated with a lower rate of unhealthy food consumption. Compared with the unexposed intervention group, the exposed intervention for the newsletter had a higher rate of healthy eating (adjusted rate ratio = 1.18; P < .01). Compared with the unexposed intervention, the exposed intervention for the community health worker discussion had a smaller hip circumference (adjusted mean difference = -5.77 cm; P < .05) and a smaller waist circumference (adjusted mean difference = -5.25 cm; P < .05).

    PubMed

    González Vélez, Ana Cristina; Jaramillo, Isabel Cristina

    2017-06-01

    In May 2006, Colombia's Constitutional Court liberalized abortion, introducing three circumstances under which the procedure would not be considered a crime: (1) rape or incest; (2) a risk to the woman's health or life; and (3) fetal malformations incompatible with life. Immediately following the court's ruling, known as Sentence C-355, members of La Mesa por la Vida y Salud de las Mujeres (hereinafter La Mesa) began to mobilize to ensure the decision's implementation, bearing in mind the limited impact that the legal framework endorsed by the court has had in other countries in the region. We argue that La Mesa's strategy is an innovative one in the field of legal mobilization insofar as it presumes that law can be shaped not just by public officials and universities but also by social actors engaged in the creation and diffusion of legal knowledge. In this regard, La Mesa has become a legal expert on abortion by accumulating knowledge about the multiple legal rules affecting the practice of abortion and about the situations in which these rules are to be applied. In addition, by becoming a legal expert, La Mesa has been able to persuade health providers that they will not risk criminal prosecution or being fired if they perform abortions. We call this effect of legal mobilization a "pedagogical effect" insofar as it involves the production of expertise and appropriation of knowledge by health professionals. We conclude by discussing La Mesa's choice to become a legal expert on abortion as opposed to recruiting academics to do this work or encouraging women to produce and disseminate this knowledge.

    To characterize the scientific output of the Revista Panamericana de Salud Pública/Pan American Journal of Public Health (RPSP) as a scientific publication of reference in the public health sector in the Americas. A descriptive cross-sectional study was conducted based on the articles published in the RPSP from 1997-2012. Bibliometric indicators of productivity (documents published, languages, authorship, and indices of productivity and collaboration); impact (impact factor according to the SciELO Network, Journal Citation Report and SCImago); key words; and bibliographic references, their structure (document type and main nucleus of Bradford) and degree of obsolescence (Burton and Kebler half-life, and Price index), were analyzed. A total of 2 815 articles with a median of 3 authors and 2 institutions per article were published. The percentage of original research articles increased in 2008-2012 compared to 2003-2007 and 1997-2002 (P < 0.001). The predominant language was Spanish, displaced by English in the last 5 years. A total of 88.76% of the key words referred to the Health Sciences Descriptors (DeCS) and had a public health and community orientation related to the Americas. The Burton and Kebler half-life of bibliographic references was 8 years, although it decreased to 5 years in 2012. The Price index was 20.47% and the nucleus of Bradford was made up of 20 mainstream journals. The percentage of self-citation was low (2.07%). The RPSP is an international publication with bibliometric indicators similar to those of the most representative Latin American health science journals, with improvements in the recent years studied that lead it to fully meet international publishing criteria.

    The present descriptive, retrospective and longitudinal study was designed to determine the epidemic profile of patients infected by hepatitis C virus and chronic hepatitis, as well as to describe the eligibility criteria for treatment with pegilated interferon plus ribavirina and its early virological answer to the treatment. We studied 20 patients treated at Gastroenterology Service of Carlos Seguín Escobedo Hospital of EsSalud between 2004 and 2006. The diagnosis of HVC infection was confirmed by detection of viral RNA with PCR, and the viral load by counting number of RNA copies. The eligibility criteria for antiviral treatment were determined, and also the METAVIR score to determine hepatic fibrosis. After 12 weeks of treatment the patients with eligibility criteria and received treatment were evaluated, and the effectivity of treatment was evaluated with a new determination of viral load. There were more female (15; 75%) than male patients (5; 25%), with ages between 50 and 59 years. The more frequent risk antecedent was blood transfusion (45%), surgery (35%), and traffic accident (10%). The hematological, hepatic, renal and hormonal parameters were in normal range; and the viral load at the moment of diagnosis was of 580 thousand copies mean (between 4100 to 2 millions copies). The most frequent viral genotypes were 1a and 1b. Up to 40% of patients did not fulfilled eligibility criteria for treatment. Nine of 12 patients with eligibility criteria received treatment (75%), 6 of them were evaluated for early virologic response and of them 100,0% had an early virologic response with decrease of post-therapeutic viral load in all but one cases until non-detectable levels. In conclusion our study described the profile of patients infected by HCV with chronic hepatitis in gastroenterology ward of our hospital, and it has been determined that is suggestive that antiviral treatment is highly effective in patients with eligibility criteria for treatment, related to

    As the cultural and linguistic diversity of the United States continues to grow and population shifts transform the communities where we live and work, health care providers continue to face challenges to deliver health services in demographically redefined terrains. This report describes the development of a Spanish-language training guide for community health workers (Guía de Capacitación para Promotoras de Salud) based on the book Nuestros Cuerpos, Nuestras Vidas (NCNV), the Spanish-language translation and cultural adaptation of the classic women's health book Our Bodies, Ourselves. The guide aims to 1) provide a tool for addressing the health education needs of immigrant Latinas and 2) facilitate the use of the book NCNV as a health education tool in Latino communities. Thirty telephone interviews with individuals working in agencies and organizations serving Latinos and 2 focus groups with Latinas were conducted to select the topics included in the training guide, all of which were drawn directly from NCNV. The guide contains 11 modules organized into 6 workshops. The modules address 11 topics related to women's health, ranging from sexuality and pregnancy to domestic violence and mental health. An ecological framework is used to deliver the health information. The materials acknowledge the roles of history, environment, culture, economic conditions, migration history, and politics as key determinants of health and illness. The workshops are designed to train community health workers on the women's health topics contained in the guide and to equip them for the delivery of health education among immigrant Latinas. © 2012 by the American College of Nurse-Midwives.

    We demonstrate that the efficiency of ion transmission from atmosphere to vacuum through stainless steel electrodes that contain slowly divergent conical duct (ConDuct) channels can be close to 100%. Here, we explore the properties of 2.5 cm long electrodes with angles of divergence of 0°, 1°, 2°, 3°, 5°, 8°, 13°, and 21°, respectively. The ion transmission efficiency was observed to jump from 10–20% for the 0° (straight) channels to 90–95% for channels with an angle of divergence as small as 1°. Furthermore, the 2–3° ConDuct electrodes produced extraordinarily low divergence ion beams that propagated in a laser-like fashion over long distances in vacuum. To take advantage of these newly discovered properties, we constructed a novel atmosphere-to-vacuum ion interface utilizing a 2° ConDuct as an inlet electrode and compared its ion transmission efficiency with that of the interface used in the commercial (Thermo) Velos Orbitrap and Q Exactive mass spectrometers. We observed that the ConDuct interface transmitted up to 17 times more ions than the commercial reference interface and also yielded improved signal-to-noise mass spectra of peptides. We infer from these results that the performance of many current atmosphere-tovacuum interfaces utilizing metal capillaries can be substantially improved by replacing them with 1° or 2° metal ConDuct electrodes, which should preserve the convenience of supplying ion desolvation energy by heating the electrode while greatly increasing the efficiency of ion transmission into the mass spectrometer.

    We demonstrate that the efficiency of ion transmission from atmosphere to vacuum through stainless steel electrodes that contain slowly divergent conical duct (ConDuct) channels can be close to 100%. Here, we explore the properties of 2.5-cm-long electrodes with angles of divergence of 0°, 1°, 2°, 3°, 5°, 8°, 13°, and 21°, respectively. The ion transmission efficiency was observed to jump from 10-20% for the 0° (straight) channels to 90-95% for channels with an angle of divergence as small as 1°. Furthermore, the 2-3° ConDuct electrodes produced extraordinarily low divergence ion beams that propagated in a laser-like fashion over long distances in vacuum. To take advantage of these newly discovered properties, we constructed a novel atmosphere-to-vacuum ion interface utilizing a 2° ConDuct as an inlet electrode and compared its ion transmission efficiency with that of the interface used in the commercial (Thermo Fisher Scientific, San Jose, CA, USA) Velos Orbitrap and Q Exactive mass spectrometers. We observed that the ConDuct interface transmitted up to 17 times more ions than the commercial reference interface and also yielded improved signal-to-noise mass spectra of peptides. We infer from these results that the performance of many current atmosphere-to-vacuum interfaces utilizing metal capillaries can be substantially improved by replacing them with 1° or 2° metal ConDuct electrodes, which should preserve the convenience of supplying ion desolvation energy by heating the electrode while greatly increasing the efficiency of ion transmission into the mass spectrometer.

  10. ConMap - a new spatial data mining framework for terrain based digital soil mapping

    NASA Astrophysics Data System (ADS)

    2009-04-01

    In this talk, we present a new digital terrain analysis framework for digital soil mapping based on spatial data mining, referred to as the contextual elevation mapping (ConMap). Aiming at integrating different scales, which can be important at landscape scale level due to interrelations of topo- and climofunctions, it comprises local surface function approximations in terms of standard local terrain attributes as well as the incorporation of geomorphic arrangements within larger neighborhoods. In contrast to common digital terrain analysis of deriving multiple terrain attributes, ConMap is based on elevation differences from the center pixel to each pixel in a local neighborhood. These differences are then used as predictors in machine learning approaches such as Random Forests. Thus, it is not necessary to choose a specific set of terrain attributes. Additionally, possibly unknown surface functions can be taken into account, as well as larger geomorphic settings. We applied and validated the framework by predicting topsoil silt content for an area of 1150 km2 in Rhineland-Palatinate and Hesse, Germany, based on 342 samples, a 20 m resolution DEM, and neighborhood sizes up to 12 km. Cross-validation R2 values increase from 0.15 for standard digital terrain analysis to 0.61 using ConMap. This effect is due to a spatial trend in the data. As ConMap is able to map this trend and as it is based on the pedological concept of integrating scales it can be seen as a new entry to spatial prediction approaches such as Kriging or Geographically Weighted Regression. We conclude that ConMap shows a great potential for future digital soil mapping studies.

    Introduccion. La epilepsia es un sindrome neurologico cronico que cursa con descargas anormales, sincronicas y exageradas de la corteza cerebral. La epilepsia se relaciona inversamente con la calidad de vida relacionada con la salud de los pacientes (CVRS); sin embargo, esta relacion se ha documentado poco en niños de Latinoamerica. Objetivo. Examinar la relacion entre epilepsia y la CVRS en un grupo de niños escolares de 8-12 años atendidos en un hospital pediatrico de Sonora, Mexico. Pacientes y metodos. Se comparo transversalmente la CVRS de niños con diagnostico de epilepsia con respecto a la CVRS de dos grupos control. Se utilizo el cuestionario validado Pediatric Quality of Life Inventory para evaluar la CVRS. Las diferencias se examinaron mediante la prueba de ANOVA, y la asociacion entre epilepsia y CVRS se modelo mediante regresion logistica multiple. Resultados. Los niños con epilepsia mostraron la menor puntuacion de CVRS (62,4 ± 14,8) entre los sujetos estudiados, y tuvieron 5,2 veces mas riesgo de deterioro de su CVRS (intervalo de confianza al 95% = 2,43-11,06) en comparacion con el de niños sanos. El deterioro fue mayor en las escalas cognitiva (54,6 ± 15,0) y emocional (55,9 ± 23,6). La polifarmacia –ingestion concomitante de tres o mas farmacos– (p < 0,001) y la progresion cronologica de la enfermedad (p < 0,001) son factores que deterioran significativamente la CVRS de niños con epilepsia. Conclusiones. La epilepsia provoca un deterioro global en la CVRS de los niños, especificamente en las esferas cognitiva y emocional, lo que se relaciona con la progresion cronologica de la enfermedad y la polifarmacia.

    Introduccion. El sindrome de Noonan (SN) y otros sindromes con fenotipo similar, como LEOPARD, cardiofaciocutaneo, Costello y Legius, estan asociados a mutaciones en genes incluidos en la via RAS/MAPK (rasopatias), una importante via de señalizacion relacionada con la proliferacion celular. El descenso de las amigdalas cerebelares dentro del canal medular cervical, conocido como malformacion de Arnold-Chiari (MAC), se ha descrito en pacientes afectos de SN, lo que ha llevado a sugerir que la MAC podria formar parte del espectro fenotipico del SN. Presentamos dos casos con SN y MAC. Casos clinicos. Caso 1: mujer de 29 años con fenotipo de Noonan. Fue intervenida a los 9 años de estenosis valvular pulmonar. A los 27 años, presento MAC sintomatica que preciso descompresion quirurgica. Presentaba mutacion c.922A>G (N308D) en el gen PTPN perteneciente a la via RAS/MAPK. Caso 2: niña de 10 años con fenotipo de Noonan y MAC asintomatica detectada en resonancia magnetica cerebral. Era portadora de la mutacion c.923A>G (N308S) en el gen PTPN11. Conclusiones. Hemos encontrado en la bibliografia seis pacientes con esta asociacion, cuatro con fenotipo Noonan y dos con LEOPARD. Nuestros dos pacientes aportan evidencia suplementaria a la hipotesis de que la MAC formaria parte del espectro fenotipico del SN. El escaso numero de pacientes publicados con esta asociacion no permite extraer recomendaciones sobre el momento y la frecuencia de estudio de neuroimagen; no obstante, una exploracion neurologica cuidadosa deberia incluirse en la guia anticipatoria de salud en los sindromes de la via RAS/MAPK.

    Los datos del estudio PREDYCES® nos revelaron que en España la desnutrición relacionada con la enfermedad (DRE) afecta a uno de cada cuatro pacientes hospitalizados. Esta cifra aumenta hasta el 36,8% en los pacientes hematológicos. Se calcula que un 20% de los pacientes oncológicos muere por complicaciones relacionadas con la DRE. Nuestro grupo se planteó en 2011 comenzar la implantación de un cribado nutricional en los servicios con mayor riesgo de DRE. La presente revisión trata de describir todo el proceso que hemos seguido para mejorar la situación nutricional en los pacientes ingresados en el Servicio de Hematología del Complejo Asistencial Universitario de León (CAULE), mayoritariamente con diagnóstico de neoplasias hematológicas. En un primer estudio piloto, detectamos una alta prevalencia de desnutrición, que tendió a aumentar durante la hospitalización. Además, solo el 8,3% los enfermos valorados recibieron algún tipo de soporte nutricional y no se estaban cubriendo sus necesidades ni calóricas ni proteicas, lo que se asociaba a un peor pronóstico. Por este motivo, nos decidimos a implantar de manera sistemática un cribado y una intervención nutricional adecuada, que comenzó en 2011 y que ha recibido el reconocimiento como Buena Práctica del Sistema Nacional de Salud.

  15. BeadCons: detection of nucleic acid sequences by flow cytometry.

    Molecular beacons are single-stranded nucleic acid structures with a terminal fluorophore and a distal, terminal quencher. These molecules are typically used in real-time PCR assays, but have also been conjugated with solid matrices. This unit describes protocols related to molecular beacon-conjugated beads (BeadCons), whose specific hybridization with complementary target sequences can be resolved by cytometry. Assay sensitivity is achieved through the concentration of fluorescence signal on discrete particles. By using molecular beacons with different fluorophores and microspheres of different sizes, it is possible to construct a fluid array system with each bead corresponding to a specific target nucleic acid. Methods are presented for the design, construction, and use of BeadCons for the specific, multiplexed detection of unlabeled nucleic acids in solution. The use of bead-based detection methods will likely lead to the design of new multiplex molecular diagnostic tools.

    Genome sequence alignments provide valuable information on many aspects of molecular biological processes. In this study, we developed a web server, GenomeCons, for manipulating multiple genome sequence alignments and their consensus sequences for high-throughput genome sequence analyses. This server facilitates the visual inspection of multiple genome sequence alignments for a set of genomic intervals at a time. This allows the user to examine how these sites are evolutionarily conserved over time for their functional importance. The server also reports consensus sequences for the input genomic intervals, which can be applied to downstream analyses such as the identification of common motifs in the regions determined by ChIP-seq experiments.

    The operational goal of the ATD-1 ConOps is to enable aircraft, using their onboard FMS capabilities, to fly Optimized Profile Descents (OPDs) from cruise to the runway threshold at a high-density airport, at a high throughput rate, using primarily speed control to maintain in-trail separation and the arrival schedule. The three technologies in the ATD-1 ConOps achieve this by calculating a precise arrival schedule, using controller decision support tools to provide terminal controllers with speeds for aircraft to fly to meet times at a particular meter points, and onboard software providing flight crews with speeds for the aircraft to fly to achieve a particular spacing behind preceding aircraft.

    Objetivo: Evaluar la rigidez de la membrana limitante interna (MLI) humana y evaluar los posibles cambios de las propiedades mecánicas tras administrar una inyección intravítrea de ocriplasmina para tratar la tracción vitreomacular. Métodos: Este estudio se compone de una serie de casos intervencionales y comparativos de 12 muestras de MLI extraídas mediante cirugía y obtenidas de forma consecutiva de 9 ojos de 9 pacientes después de someterse sin éxito a vitreólisis farmacológica con ocriplasmina. Durante el mismo periodo de tiempo, 16 muestras de otros 13 ojos sin tratamiento con ocriplasmina se obtuvieron mediante vitrectomía y sirvieron como controles. Todos los pacientes presentaron agujeros maculares o tracción vitreomacular y se sometieron a vitrectomía con disección de la MLI tanto con tinción con azul brillante (AB) como sin ella. Todas las muestras se analizaron con un microscopio de fuerza atómica con imágenes de las regiones de 25 × 25 μm. En todas las muestras, se analizaron tanto la parte de la retina como la del vítreo de la MLI. Resultados: La microscopia de fuerza atómica no reveló diferencias significativas en cuanto a elasticidad de las muestras de MLI extraídas de ojos con o sin tratamiento con ocriplasmina. Las áreas onduladas de la parte de la retina presentaron una mayor rigidez que la parte del vítreo de la MLI. La cartografía topográfica tanto de la parte del vítreo como de la retina de la MLI no mostró ninguna alteración aparente de la morfología en ojos tratados con ocriplasmina en comparación con los ojos no tratados. La tinción con azul brillante conllevó un aumento de la rigidez tisular. Conclusiones: Las inyecciones intravítreas de ocriplasmina no varían las propiedades biomecánicas de la MLI humana. No existen pruebas de un posible efecto enzimático que interfiera con la rigidez de esta membrana basal. © 2017 S. Karger AG, Basel.

  20. Extreme lateral lumbar interbody fusion: Do the cons outweigh the pros?

    Epstein, Nancy E.

    2016-01-01

    Background: Major factors prompted the development of minimally invasive (MIS) extreme lateral interbody fusion (XLIF; NuVasive Inc., San Diego, CA, USE) for the thoracic/lumbar spine. These include providing interbody stabilization and indirect neural decompression while avoiding major visceral/vessel injury as seen with anterior lumbar interbody fusion (ALIF), and to avert trauma to paraspinal muscles/facet joints found with transforaminal lumbar interbody fusion (TLIF), posterior lumbar interbody fusion (PLIF), and posterior-lateral fusion techniques (PLF). Although anticipated pros of MIS XLIF included reduced blood loss, operative time, and length of stay (LOS), they also included, higher fusion, and lower infection rates. Unanticipated cons, however, included increased morbidity/mortality rates. Methods: We assessed the pros and cons (e.g., risks, complications, comparable value/superiority/inferiority, morbidity/mortality) of MIS XLIF vs. ALIF, TLIF, PLIF, and PLF. Results: Pros of XLIF included various biomechanical and technical surgical advantages, along with multiple cons vs. ALIF, TLIF, PLIF, and PLF. For example, XLIF correlated with a considerably higher frequency of major neurological deficits vs. other constructs; plexus injuries 13.28%, sensory deficits 0–75% (permanent in 62.5%), motor deficits 0.7–33.6%, and anterior thigh pain 12.5–25%. XLIF also disproportionately contributed to other major morbidity/mortality; sympathectomy, major vascular injuries (some life-ending others life-threatening), bowel perforations, and seromas. Furthermore, multiple studies documented no superiority, and the potential inferiority of XLIF vs. ALIF, TLIF, PLIF, and PLF. Conclusion: Reviewing the pros of XLIF (e.g. radiographic, technical, biomechanical) vs. the cons (inferiority, increased morbidity/mortality) vs. ALIF, TLIF, PLIF, and PLF, we question whether XLIF should remain part of the lumbar spinal surgical armamentarium.

    Complementando una línea de trabajo iniciada con anterioridad discutimos la estabilidad del espectrógrafo REOSC de CASLEO en DC para la medición de velocidades radiales en base al análisis de observaciones realizadas en enero y abril de 1997. En esas oportunidades obtuvimos 26 espectros de estrellas patrones y 27 espectros de 3 estrellas usadas como estrellas de referencia en nuestro programa de cúmulos abiertos. Además tomamos 26 espectros de crepúsculo con el telescopio en posiciones cubriendo el rango H=-4,+4 y δ =-90,+30. Mediante correlaciones cruzadas derivamos la velocidad de 19 órdenes en cada uno de estos espectros. En base a un análisis estadístico de los datos obtenidos discutimos la contribución de los distintos factores que afectan a la dispersión de lectura observada. En particular, la flexión del instrumento no introduciría errores significativos cuando se observa con masas de aire menores que 2.0. La dispersión de los valores de velocidad medidos para espectros de alta relación S/N de una misma estrella resultó del orden de 0.5 km/s. La comparación con los valores de velocidad publicados por distintos autores para las estrellas patrones no permite distinguir ninguna diferencia sistemática apreciable de las velocidades de CASLEO, siendo la media cuadrática de los residuos del orden de 1.0 km/s.

    BACKGROUND There is a need for culturally-relevant nutrition programs targeted to underserved cancer survivors. OBJECTIVE To examine the effect of a culturally-based approach to dietary change on increasing fruit/vegetable intake and decreasing fat intake among Hispanic breast cancer (BC) survivors. DESIGN Participants were randomized to intervention (IG) and control (CG) groups. Diet recalls, detailed interviews, fasting blood, and anthropometric measures were collected at baseline, 3-, 6- and 12-months. PARTICIPANTS/SETTING Hispanic women (n=70) with stage 0-III BC who completed adjuvant treatment and lived in New York City were randomized between April 2011 and March 2012. INTERVENTION The IG (n=34) participated in ¡Cocinar Para Su Salud! (¡CPSS!), a culturally-based 9-session (24-hours over 12 weeks) intervention including nutrition education, cooking classes and food shopping field trips. The CG (n=36) received written dietary recommendations for BC survivors. MAIN OUTCOME MEASURES Change at 6 months in daily fruit/vegetable servings and % calories from total fat. STATISTICAL ANALYSES Linear regression models adjusted for stratification factors and estimated marginal means were used to compare changes in diet from baseline to 3- and 6-months. RESULTS Baseline characteristics: mean age 56.6 years (SD 9.7), mean time since diagnosis 3.4 years (SD 2.7), mean BMI 30.9 kg/m2 (SD 6.0), 62.9% with annual household income ≤$15,000, average daily servings of all fruits/vegetables 5.3 (targeted fruits/vegetables 3.7 servings excluding legumes/juices/starchy vegetables/fried foods) and 27.7% of daily calories from fat. Over 60% in the IG attended ≥7/9 classes with overall study retention of 87% retention at 6 months. At month 6, the IG compared to CG reported an increase in mean servings of fruits/vegetables from baseline (all fruits/vegetables: +2.0 vs. −0.1, P=0.005; targeted fruits/vegetables: +2.7 vs. +0.5, P=0.002) and a non-significant decrease in

    Meta Salud was a community health worker-facilitated intervention for the prevention of noncommunicable diseases in Northern Mexico. This analysis examined changes in perceived health, eating habits, and physical activity immediately and 3 months after the intervention. The impact on the resulting behavioral and psychological factors are reported. This was a nonrandomized intervention study with 1 baseline and 2 post-intervention follow-ups. Outcome evaluation consisted of anthropometric measurements, laboratory tests, and a lifestyle questionnaire. The most consistent patterns were increases in metabolic equivalent of task values expended per day from baseline to post-intervention (difference = 996; 95% confidence interval [CI]: 81 to 1,912) and to 3-month follow-up (difference = 1,073; 95% CI: 119 to 2,028); greater likelihood of meeting Centers for Disease Control and Prevention daily exercise recommendations, with an increase from 49% to 60% at post-intervention (OR: 1.6, 95% CI: 1.0 to 2.4) and 63% at follow-up (OR: 1.7, 95% CI: 1.7 to 2.7); lesser likelihood for consuming whole milk, from 38% to 59% (OR: 2.9, 95% CI: 1.8 to 4.7); fewer daily servings of packaged foods, from 0.72 to 0.57 (difference = -0.16; 95% CI: -0.28 to -0.03); fewer days of poor mental health, from 9.3 to 5.8 (difference = -3.4; 95% CI: -5.1 to -1.7); and greater likelihood for reporting good self-rated health, from 41% to 54% post-intervention (OR: 2.1, 95% CI: 1.3 to 3.6) and 57% at follow-up (OR: 2.5, 95% CI: 1.5 to 4.4). Changes in other outcomes, although in the expected direction of association, were not statistically significant. The study identified important strategies for making feasible dietary changes in the consumption of whole milk, sugary drinks, and packaged foods, yet there is still a need to identify strategies for improving consumption of healthy foods. There was stronger evidence for ways of improving physical activity as opposed to other outcome measures

El coeficiente de expansión se calcula para sectores radiales de 4o de ancho cada uno, ajustando la correlación cruzada de las derivadas de los perfiles promedio para cada época. A partir de la expansión medida, se estima el índice (parámetro de expansión) de la ley potencial R∝ tm como m≡ d ln R/d ln t . Este valor se compara con coeficientes teóricos para diferentes fases evolutivas de remanentes de supernova.

    Magnetic resonance diffusion-weighted imaging coupled with fiber tractography (DFT) is the only non-invasive method for measuring white matter pathways in the living human brain. DFT is often used to discover new pathways. But there are also many applications, particularly in visual neuroscience, in which we are confident that two brain regions are connected, and we wish to find the most likely pathway forming the connection. In several cases, current DFT algorithms fail to find these candidate pathways. To overcome this limitation, we have developed a probabilistic DFT algorithm (ConTrack) that identifies the most likely pathways between two regions. We introduce the algorithm in three parts: a sampler to generate a large set of potential pathways, a scoring algorithm that measures the likelihood of a pathway, and an inferential step to identify the most likely pathways connecting two regions. In a series of experiments using human data, we show that ConTrack estimates known pathways at positions that are consistent with those found using a high quality deterministic algorithm. Further we show that separating sampling and scoring enables ConTrack to identify valid pathways, known to exist, that are missed by other deterministic and probabilistic DFT algorithms.

    The degree of evolutionary conservation of an amino acid in a protein or a nucleic acid in DNA/RNA reflects a balance between its natural tendency to mutate and the overall need to retain the structural integrity and function of the macromolecule. The ConSurf web server (http://consurf.tau.ac.il), established over 15 years ago, analyses the evolutionary pattern of the amino/nucleic acids of the macromolecule to reveal regions that are important for structure and/or function. Starting from a query sequence or structure, the server automatically collects homologues, infers their multiple sequence alignment and reconstructs a phylogenetic tree that reflects their evolutionary relations. These data are then used, within a probabilistic framework, to estimate the evolutionary rates of each sequence position. Here we introduce several new features into ConSurf, including automatic selection of the best evolutionary model used to infer the rates, the ability to homology-model query proteins, prediction of the secondary structure of query RNA molecules from sequence, the ability to view the biological assembly of a query (in addition to the single chain), mapping of the conservation grades onto 2D RNA models and an advanced view of the phylogenetic tree that enables interactively rerunning ConSurf with the taxa of a sub-tree. © The Author(s) 2016.

    Introduction Electronic monitoring devices (EMDs) are the optimal method for collecting objective data on inhaler use in asthma. Recent research has investigated the attitudes of patients with asthma towards these devices. However, no research to date has formally considered the opinions of stakeholders and decision-makers in asthma care. These individuals have important clinical requirements that need to be taken into account if EMDs are to be successfully provisioned, making collecting their opinions on the key barriers facing these devices a valuable process. Methods Three rounds of surveys in a Delphi format were used to assess the most important pros and cons of EMDs for asthma care in a sample of 31 stakeholders which included healthcare professionals and members of clinical commissioning groups. Results The respondents identified 29 pros and 32 cons. Pros that were rated as most important included new visual evidence to aid clinical discussions with a patient and an increase in patient involvement and motivation. The cons that were rated as most important included a need for more clinical evidence of the effectiveness of EMDs, as well as better clarity over who has responsibilities in managing, interpreting and discussing data with a patient. Conclusions The research provides a guide for EMD developers by highlighting where these devices may provide the most benefit as well as prioritising the key issues that need addressing if they are to be used effectively in everyday asthma care.

    1994-12-01

    A portion of the abandoned Miami-Erie Canal paralleling the Greater Miami River receives the runoff and storm-water discharge from Mound Laboratory. In 1969, a low-level plutonium leak contaminated sediment as far away as 1.5 mi from the Mound site along the old canal system. An estimated one million cubic feet of sediment requires remediation. The technology being evaluated for the remediation of the low-level plutonium-238 contamination of the sediment involves two processes: washing the sediments with ACT*DE*CON{sup SM} solution to dissolve the contaminant, followed by extraction of the solution and processing with the MAG*SEP{sup SM} process to concentrate the contaminant and allow reuse of the ACT*DE*CON{sup SM} solution. The processes are being optimized for pilot-scale and field demonstration. Phase 2 of the project primarily involved identification at the laboratory scale of the optimal ACT*DE*CON{sup SM} formulation, identification of the ion-exchanger and MAG*SEP{sup SM} particles, verification of the plutonium mobility in the treated soil, and evaluation of other process parameters according to a series of tasks.

    Mucoepidermoid carcinoma (MEC) corresponds to 5-12% of all salivary gland tumours, and is classified as low, intermediate or high grade. Traditionally, immunohistochemistry was considered as the complementary tool for diagnosis of salivary gland neoplasia. Lectin histochemistry has also been increasingly used in recent years. In this work, lectins were used as histochemical markers for normal and transformed parotid glands. Biopsy specimens of 15 cases diagnosed as MEC (low, intermediate and high grade) of the parotid gland were trypsin- and methanol-H(2)O(2)-treated and incubated with horseradish peroxidase (HRP)-conjugated lectins, Concanavalin A (Con A-HRP) and Ulex europeus I (UEA-I-HRP). Con A stained the neoplasic cells of MEC (all grades). In high and intermediate cases, ductal cells were weakly stained by Con A. UEA-I weakly stained normal cells of the excretory duct and neoplasic cells in high grade. Neoplasic cells in intermediate grade were moderately stained and in low grade, the cell membrane was intensely stained with UEA-I. Stroma presented a direct relation between malignancy and staining intensity for UEA-I. The results indicated that lectin histochemistry distinguished the cell biology among histological grades of MEC.

    Recent exploration of the south east Nam Con Son Basin, offshore Vietnam, by BP in alliance with Statoil has involved acquisition of new seismic and well data. These new data have allowed re-evaluation of the tectono-stratigraphic development and petroleum geology, and have provided additional constraints on the regional tectonic evolution. The offshore Vietnamese basins have evolved in response to the complex relative motions of Indochina, Peninsular Malaysia, Borneo and the South China Sea during the Cenozoic. On the regional scale these motions have been accommodated by strike-slip fault development, rifting and contraction. In the Nam Con Son Basin these motions have interacted in different ways from the Palaeogene to recent. Two rifting episodes are recognized; a Palaeogene phase dominated by E-W trending extensional faults, and a Miocene phase dominated by N-S to NE-SW trending faults. The structural evolution is complicated by a pulse of mild contraction during the Middle Miocene. The sedimentary fill of the basin evolves from continental fluvio-lacustrine in the Palaeogene through to fully marine following the second phase of rifting in the Miocene. This pulsed structural and stratigraphic evolution has resulted in basinwide deposition of source, reservoir and seal facies, and produced a variety of potential trapping styles. This paper describes the hydrocarbon habitat of the south east Nam Con Son Basin within the context of the regional tectono-stratigraphic model.

    SUMMARY The frequency of anti-Toxocara spp. antibodies in individuals attended by the Centro de Salud Familiar in the coastal Niebla town, Chile, was related to the host and to environmental factors. IgG anti- Toxocara antibodies were detected with a commercial ELISA kit (SCIMEDX Corporation, USA). Samples with undetermined absorbance values were subjected to an additional ELISA standardized by the Instituto de Salud Pública, Chilean Health Ministry, a commercial ELISA (NOVATEC, Germany), and a commercial Western blot kit (LDBio Diagnostics, France). Hematological exams were performed using an automated blood counter and blood smears. Dog feces were collected from the ground along the main road in Niebla, including rural and urban locations. Ninety (25.4%) of the 355 examined individuals were positive by the ELISA test. The frequency of anti-Toxocara antibodies and the infection risk were significantly higher (p < 0.05) among those individuals ≥ 40 years old with respect to the 20-39 years old group, in individuals from rural locations, those who did not have a safe drinking water supply in the house or who presented blood eosinophilia. The proportion of positive samples of dog feces and the mean number of Toxocara canis eggs/g of feces in urban and rural areas were similar (p > 0.05). PMID:27680167

    Equilibrium geometries, relative stabilities, electronic stabilities and magnetic properties of ConSn (n = 1-12) clusters have been systematically investigated by using relativistic all-electron density functional theory with generalized gradient approximation. The results indicated that the lowest-energy structures of ConSn (n = 1-5, 7, 9 and 10) clusters are similar to those of corresponding Con+1 clusters. As for Co6Sn, Co8Sn, Co11Sn and Co12Sn clusters, the most stable structures give rise to a geometry reconstruction. In the low-lying structures of ConSn (n = 1-12) clusters, tin impurity prefers to occupy the external site. The second-order difference energy of the ground-state ConSn (n = 1-12) clusters shows a pronounced odd-even oscillation with the number of Co atoms, and the clusters exhibit higher stability at n = 5. Compared with corresponding pure Con+1 clusters, the total magnetic moment of the ConSn clusters reduces with 1, 3 and 5 μB, respectively. The different magnetic changes of the tin doped Co clusters are analyzed in detail based on the magnetism coupling, density of state and hybridization between cobalt and tin atoms.

    Previous studies have demonstrated the essential role of morphogenetic regulation in Fusarium oxysporum pathogenesis, including processes such as cell-wall biogenesis, cell division, and differentiation of infection-like structures. We identified three F. oxysporum genes encoding predicted transcription factors showing significant identities to Magnaporthe oryzae Con7p, Con7-1, plus two identical copies of Con7-2. Targeted deletion of con7-1 produced nonpathogenic mutants with altered morphogenesis, including defects in cell wall structure, polar growth, hyphal branching, and conidiation. By contrast, simultaneous inactivation of both con7-2 copies caused no detectable defects in the resulting mutants. Comparative microarray-based gene expression analysis indicated that Con7-1 modulates the expression of a large number of genes involved in different biological functions, including host-pathogen interactions, morphogenesis and development, signal perception and transduction, transcriptional regulation, and primary and secondary metabolism. Taken together, our results point to Con7-1 as general regulator of morphogenesis and virulence in F. oxysporum.

    Using the characteristics of T cell mitogen called lectin protein from the jack-beam Canavalia ensiformis Concanavalin A (Con_A) with dual activities, cytotoxicity and immunomodulation, we have shown it has a therapeutic effect on hepatoma. Injection of Con_A can eradicate the established malign tumor, because Con_A can induce tumor cell autophagic, cell-programmed death, as well as activate the effector T cells. Combined, in this paper, with the absorption exceeding the Carbon NanoTube (CNT) band-gap (ɛbg=~1/CNT diameter) with an active short wave near-infrared (SWIR) (1.2~1.5 micron wavelengths), which happened to be translucent to the irradiation upon animal skin, similar to that used in hospital fingertip-clamped Pulse Oxymetry. Once the Con_ACNT is guided to hepatoma cells, it is bonded and internalized into the mitochondria (MC) compartment, the cellular energy factory. Con_A has the higher specificity for tumor cells useful for targeting because of the abnormal glycosylation on tumor cells. When CNT hitch hike with Con_A, they can t together like a laser-denotable chemical missile surgically targeting at the tumor cells precisely by Con_A-guidance. We switch on SWIR laser, when the Con_A-CNT conjugated complex has been bonded and internalized to MC of malign cells and already commenced cellular programmed death. Thus, it might appear to casual readers that we have initiated an overkill, chemical drugged autophage followed with physical laser ablation, but what if we can eradicate hepatoma totally if no blue print is left behind inadvertently in case of a partial failure. We conclude that using Con_A-CNT conjugated complex targeting specifically at malign tumor cells is a novel targeted-laser-radiation therapy for tumors in mice.

  1. Wildland Fire Induced Heating of Dome 375 Perma-Con®

    AET-1 was tasked by ADEM with determining the temperature rise in the drum contents of drums stored in the Dome 375 Perma-Con® at TA-54 given a wildland fire. The wildland fire causes radiative and convective heating on the Perma-Con® exterior. The wildland fire time histories for the radiative and convective heating environment were provided to AET-1 by EES-16. If the calculated temperature rise results in a drum content temperature over 40 °C, then ADEM desires a design solution to ensure the peak temperature remains below 40 °C. An axi-symmetric FE simulation was completed to determine the peak temperature of the contents of a drum stored in the Dome 375 Perma-Con® during a wildland fire event. Three wildland fire time histories for the radiative and convective heat transfer were provided by EES-16 and were inputs for the FE simulation. The maximum drum content temperature reached was found to be 110 °C while using inputs from the SiteG_2ms_4ign_wind_from_west.xlsx time history input and not including the SWB in the model. Including the SWB in the results in a peak drum content temperature of 61 °C for the SiteG_2ms_4ign_wind_from_west.xlsx inputs. EES-16 decided that by using fuel mitigation efforts, such as mowing the grass and shrubs near the Perma-Con® they could reduce the shrub/grass fuel loading near the Perma-Con® from 1.46 kg/m2 to 0.146 kg/m2 and by using a less conservative fuel loading for the debris field inside the Dome 375 perimeter, reducing it from 0.58 kg/m2 to 0.058 kg/m2 in their model. They also greatly increased the resolution of their radiation model and increased the accuracy of their model’s required convergence value. Using this refined input the maximum drum content temperature was found to be 28 °C with no SWB present in the model. Additionally, this refined input model was modified to include worst case emissivity values for the concrete, drum and Perma-Con® interior, along with adding a

    Introducción: Los cambios en la conducta alimentaria de los estudiantes universitarios son comunes y se han estudiado ampliamente. Aunque el riesgo de desarrollo de trastornos de la alimentación parece ser obvio entre los estudiantes de nutrición, hay una falta de investigación en este campo. Este estudio se propuso: determinar el riesgo de desarrollar trastornos de la alimentación en los estudiantes de Dietética y Nutrición mediante la comparación entre las conductas alimentarias, los hábitos dietéticos, el estado nutricional, la composición corporal y la actividad física con respecto a la de otros estudiantes (de grados de la salud y no relacionados con la salud). Métodos: Estudio comparativo transversal. La muestra comprendía 189 estudiantes mujeres, con edades entre 18 y 25 años (20,3 ± 2,0) de dos universidades públicas portuguesas. En todas las estudiantes se midió el peso, la talla, el porcentaje de masa grasa y la circunferencia de la cintura, y todas ellas contestaron cuatro cuestionarios validados que evaluaban la conducta alimentaria, los patrones de alimentación y la actividad física. Resultados: Hubo un riesgo bajo de desarrollar trastornos de la alimentación en estas estudiantes (4,2%). No hubo diferencias significativas entre las estudiantes de DN, salud y otras disciplinas no relacionadas con la salud con respecto a la conducta alimentaria, el estado nutricional o la composición corporal, lo que contrastaba con diferencias en algunos hábitos dietéticos y la actividad física (p < 0,05). Conclusiones: A pesar del riesgo bajo de trastornos de la alimentación entre las estudiantes de DN, un gran porcentaje de ellas tenía preocupación por el peso corporal. Las estudiantes de DN tenían los mayores porcentajes de peso normal, ausencia de riesgo cardiometabólico de acuerdo a la circunferencia de la cintura y la masa grasa normal. Estas estudiantes tenían los hábitos dietéticos más saludables y también practicaban una

Métodos: Se aleatorizó el uso de FP o FLAC en ochenta ojos con RDP y EMD con afectación central de la mácula. Ambos grupos tuvieron una evaluación de base de mejor agudeza visual corregida y fueron examinados con tomografía de coherencia óptica y angiografía con fluoresceína. Resultados: El número medio de disparos de láser en los grupos de FP y FLAC fue 1.726,10 y 752,00 en la sesión 1 y 1.589,00 y 830,00 (p < 0,001) en la sesión 2, respectivamente. El grosor foveal central (GFC) medio antes de comenzar el estudio fue 306 ± 100 y 314 ± 98 en los grupos de FP y FLAC, respectivamente. A las 8 semanas, el GFC medio fue 332 ± 116 y 347 ± 111 en los grupos de FP y FLAC, respectivamente (p > 0,05). La MAVC media fue similar durante el periodo de estudio y no hubo ninguna diferencia significativa entre los grupos (p > 0,05). Conclusiones: El FP y el FLAC mostraron efectos similares en el EMD en ojos con RDP y fueron igualmente seguros sin un aumento significativo del GFC. © 2017 S. Karger AG, Basel.

    1986-01-01

    The plant lectin concanavalin A (Con A) has been used in an invertebrate model of lectin-dependent cell-mediated cytotoxicity (LDCC). Macrophage-like cells from the susceptible host snail Biomphalaria glabrata become cytotoxic effectors when they encounter sporocysts of the parasitic trematode Schistosoma mansoni that have been treated with Con A. The sugar alpha-methyl mannoside and rabbit anti-Con A antibodies fail to block this LDCC. Con A is effective only when the target, not the effector cell, has been exposed to it. These results constitute evidence against the molecular bridging hypothesis and support the notion that surface modulation of the target may be the stimulus that provokes cytotoxicity. Results from this invertebrate model are discussed in the context of murine T lymphocyte LDCC. PMID:3949370

    TransCon growth hormone is a sustained-release human growth hormone prodrug under development in which unmodified growth hormone is transiently linked to a carrier molecule. It is intended as an alternative to daily growth hormone in the treatment of growth hormone deficiency. This was a multi-center, randomized, open-label, active-controlled trial designed to compare the safety (including tolerability and immunogenicity), pharmacokinetics and pharmacodynamics of three doses of weekly TransCon GH to daily growth hormone (Omnitrope). Thirty-seven adult males and females diagnosed with adult growth hormone deficiency and stable on growth hormone replacement therapy for at least 3 months were, following a wash-out period, randomized (regardless of their pre-study dose) to one of three TransCon GH doses (0.02, 0.04 and 0.08 mg GH/kg/week) or Omnitrope 0.04 mg GH/kg/week (divided into 7 equal daily doses) for 4 weeks. Main outcomes evaluated were adverse events, immunogenicity and growth hormone and insulin-like growth factor 1 levels. TransCon GH was well tolerated; fatigue and headache were the most frequent drug-related adverse events and reported in all groups. No lipoatrophy or nodule formation was reported. No anti-growth hormone-binding antibodies were detected. TransCon GH demonstrated a linear, dose-dependent increase in growth hormone exposure without accumulation. Growth hormone maximum serum concentration and insulin-like growth factor 1 exposure were similar after TransCon GH or Omnitrope administered at comparable doses. The results suggest that long-acting TransCon GH has a profile similar to daily growth hormone but with a more convenient dosing regimen. These findings support further TransCon GH development. © 2017 The authors.

    In this work we normalize a SEIR model that incorporates exponential natural birth and death, as well as disease-caused death. We use optimal control to control by vaccination the spread of a generic infectious disease described by a normalized model with L1 cost. We discuss the pros and cons of SEIR normalized models when compared with classical models when optimal control with L1 costs are considered. Our discussion highlights the role of the cost. Additionally, we partially validate our numerical solutions for our optimal control problem with normalized models using the Maximum Principle.

    2011-02-01

    For last one decade, scientists are working for developing nano anti-cancer drugs with claim of ideal ones due to their targeted chemotherapic nature. These drugs have many beneficial properties such as targeted drug delivery and gene therapy modalities with minimum side effects. This article describes pros and cons and future perspectives of nano anti-cancer drugs. Efforts have been made to address importance, special features, toxicities (general, blood identities, immune system and environmental) and future perspectives of nano anti-cancer drugs. It was concluded that nano anti-cancer drugs may be magic bullet drugs for cancer treatment leading to bright future of the whole world.

    In the last decade, so-called hard-core smokers have received increasing interest in research literature. For smokers in general, the study of perceived costs and benefits (or 'pros and cons') of smoking and quitting is of particular importance in predicting motivation to quit and actual quitting attempts. Therefore, this study aims to gain insight into the perceived pros and cons of smoking and quitting in hard-core smokers. We conducted 11 focus group interviews among current hard-core smokers (n = 32) and former hard-core smokers (n = 31) in the Netherlands. Subsequently, each participant listed his or her main pros and cons in a questionnaire. We used a structural procedure to analyse the data obtained from the group interviews and from the questionnaires. Using the qualitative data of both the questionnaires and the transcripts, the perceived pros and cons of smoking and smoking cessation were grouped into 6 main categories: Finance, Health, Intrapersonal Processes, Social Environment, Physical Environment and Food and Weight. Although the perceived pros and cons of smoking in hard-core smokers largely mirror the perceived pros and cons of quitting, there are some major differences with respect to weight, social integration, health of children and stress reduction, that should be taken into account in clinical settings and when developing interventions. Based on these findings we propose the 'Distorted Mirror Hypothesis'.

    The importance of findings derived from syntheses of qualitative research has been increasingly acknowledged. Findings that arise from qualitative syntheses inform questions of practice and policy in their own right and are commonly used to complement findings from quantitative research syntheses. The GRADE approach has been widely adopted by international organisations to rate the quality and confidence of the findings of quantitative systematic reviews. To date, there has been no widely accepted corresponding approach to assist health care professionals and policy makers in establishing confidence in the synthesised findings of qualitative systematic reviews. A methodological group was formed develop a process to assess the confidence in synthesised qualitative research findings and develop a Summary of Findings tables for meta-aggregative qualitative systematic reviews. Dependability and credibility are two elements considered by the methodological group to influence the confidence of qualitative synthesised findings. A set of critical appraisal questions are proposed to establish dependability, whilst credibility can be ranked according to the goodness of fit between the author's interpretation and the original data. By following the processes outlined in this article, an overall ranking can be assigned to rate the confidence of synthesised qualitative findings, a system we have labelled ConQual. The development and use of the ConQual approach will assist users of qualitative systematic reviews to establish confidence in the evidence produced in these types of reviews and can serve as a practical tool to assist in decision making.

    The potential impact of cogeneration in office and apartment buildings in New York City on the Consolidated Edison Company (Con Ed) has been investigated using a method of utility cost and fuel use analysis developed at Brookhaven National Laboratory. This method computes a utility's long run marginal costs and long run marginal fuel consumption associated with load modifications due to the introduction of on-site energy producing technologies. The principal findings of this study show that Con Ed's long run average cost is more likely to go down than up due to cogeneration in office and apartment building; the utility's avoided costs (i.e., its long run marginal savings) associated with the gross power output of the cogeneration systems are 10.5 cents/KWh for the office building and 6.4 cents/KWh for the apartment buildings; the utility's marginal savings include a component for avoided capacity costs; and there are net savings in the use of oil due to cogeneration (assuming the building used oil for its boilers before it switched and diesel fuel in its cogenerators afterwards).

    The aim of this study was to evaluate the reliability of isokinetic and isometric assessments of the knee extensor and the flexor muscle function using the Con-Trex isokinetic dynamometer. Thirty healthy subjects (15 males, 15 females) were tested and retested 7 days later for maximal strength (isokinetic peak torque, work, power and angle of peak torque as well as isometric maximal voluntary contraction torque and rate of torque development) and fatigue (per cent loss and linear slope of torque and work across a series of 20 contractions). For both the knee extensor and the flexor muscle groups, all strength data - except angle of peak torque - demonstrated moderate-to-high reliability, with intraclass correlation coefficients (ICC) higher than 0.86. The highest reliability was observed for concentric peak torque of the knee extensor muscles (ICC = 0.99). Test-retest reliability of fatigue variables was moderate for the knee extensor (ICC range 0.84-0.89) and insufficient-to-moderate for the knee flexor muscles (ICC range 0.78-0.81). The more reliable index of muscle fatigue was the linear slope of the decline in work output. These findings establish the reliability of isokinetic and isometric measurements using the Con-Trex machine.

  18. Quick fix or long-term cure? Pros and cons of bariatric surgery

    2012-01-01

    The past decade has seen an enormous increase in the number of bariatric, or weight loss, operations performed. This trend is likely to continue, mirroring the epidemic of obesity around the world and its rising prevalence among children. Bariatric surgery is considered by many to be the most effective treatment for obesity in terms of maintenance of long-term weight loss and improvement in obesity-related comorbid conditions. Although overly simplified, the primary mechanisms of the surgical interventions currently utilized to treat obesity are the creation of a restrictive or malabsorptive bowel anatomy. Operations based on these mechanisms include the laparoscopic adjustable gastric band and laparoscopic vertical sleeve gastrectomy (considered primarily restrictive operations), the laparoscopic biliopancreatic diversion with or without a duodenal switch (primarily malabsorptive operation), and the laparoscopic Roux-en-Y gastric bypass (considered a combination restrictive and selective malabsorptive procedure). Each operation has pros and cons. Important considerations, for the patient and surgeon alike, in the decision to proceed with bariatric surgery include the technical aspects of the operation, postoperative complications including long-term nutritional problems, magnitude of initial and sustained weight loss desired, and correction of obesity-related comorbidities. Herein, the pros and cons of the contemporary laparoscopic bariatric operations are reviewed and ongoing controversies relating to bariatric surgery are discussed: appropriate patient selection, appropriate operation selection for an individual patient, surgeon selection, and how to measure success after surgery.

    Concanavalin A (ConA) is a well characterized and extensively used lectin accumulated in the protein bodies of jack bean cotyledons. ConA is synthesized as an inactive precursor proConA. The maturation of inactive proConA into biologically active ConA is a complex process including the removal of an internal glycopeptide and a C-terminal propeptide (CTPP), followed by a head-to-tail ligation of the two largest polypeptides. The cDNA encoding proConA was cloned and expressed in tobacco BY-2 cells. ProConA was slowly transported to the vacuole where its maturation into ConA was similar to that in jack bean cotyledons, apart from an incomplete final ligation. To investigate the role of the nine amino acid CTPP, a truncated form lacking the propeptide (proConADelta9) was expressed in BY-2 cells. In contrast to proConA, proConADelta9 was rapidly chased out of the endoplasmic reticulum (ER) and secreted into the culture medium. The CTPP was then fused to the C-terminal end of a secreted form of green fluorescent protein (secGFP). When expressed in tobacco BY-2 cells and leaf protoplasts, the chimaeric protein was located in the vacuole whereas secGFP was located in the culture medium and in the vacuole. Altogether, our results show we have isolated a new C-terminal vacuolar sorting determinant.

    Competitive binding assays based on the lectin Concanavalin A (ConA) have displayed significant potential to serve in continuous glucose monitoring applications. However, to date, this type of fluorescent, affinity-based assay has yet to show the stable, glucose predictive capabilities that are required for such an application. This instability has been associated with the extensive crosslinking between traditionally-used fluorescent ligands (presenting multiple low-affinity moieties) and ConA (presenting multiple binding sites) in free solution. The work herein introduces the design and synthesis of a new type of fluorescent ligand that can avoid this aggregation and allow the assay to be sensitive across the physiologically relevant glucose concentration range. This fluorescent ligand (APTS–MT) presents a single high-affinity trimannose moiety that is recognized by ConA’s full binding site and a fluorophore that can effectively track the ligand’s equilibrium binding via fluorescent anisotropy. This is confirmed by comparing its measured fluorescent lifetime to experimentally-determined rotational correlation lifetimes of the free and bound populations. Using an assay comprised of 200 nM APTS–MT and 1 μM ConA, the fluorescence anisotropy capably tracks the concentration of monosaccharides that are known to bind to ConA’s primary binding site, and the assay displays a MARD of 6.5% across physiologically relevant glucose concentrations. Ultimately, this rationally-designed fluorescent ligand can facilitate the realization of the full potential of ConA-based glucose sensing assays and provide the basis for a new set of competing ligands to be paired with ConA.

    The ability of a cue-based system to accurately assert whether a disorder is affirmed, negated, or uncertain is dependent, in part, on its cue lexicon. In this paper, we continue our study of porting an assertion system (pyConTextNLP) from English to Swedish (pyConTextSwe) by creating an optimized assertion lexicon for clinical Swedish. We integrated cues from four external lexicons, along with generated inflections and combinations. We used subsets of a clinical corpus in Swedish. We applied four assertion classes (definite existence, probable existence, probable negated existence and definite negated existence) and two binary classes (existence yes/no and uncertainty yes/no) to pyConTextSwe. We compared pyConTextSwe's performance with and without the added cues on a development set, and improved the lexicon further after an error analysis. On a separate evaluation set, we calculated the system's final performance. Following integration steps, we added 454 cues to pyConTextSwe. The optimized lexicon developed after an error analysis resulted in statistically significant improvements on the development set (83% F-score, overall). The system's final F-scores on an evaluation set were 81% (overall). For the individual assertion classes, F-score results were 88% (definite existence), 81% (probable existence), 55% (probable negated existence), and 63% (definite negated existence). For the binary classifications existence yes/no and uncertainty yes/no, final system performance was 97%/87% and 78%/86% F-score, respectively. We have successfully ported pyConTextNLP to Swedish (pyConTextSwe). We have created an extensive and useful assertion lexicon for Swedish clinical text, which could form a valuable resource for similar studies, and which is publicly available.

    Phenotypic detection of methicillin resistance in coagulase-negative Staphylococcus (CoNS) of animal origin has been challenging due to the heterogeneous expression of mecA. To compare different phenotypic methods in predicting the mecA presence in CoNS, a total of 87 CoNS isolates from agricultural animals were analyzed in this study by agar dilution, disk diffusion, and broth microdilution. mecA was present in 81 CoNS isolates. Broth microdilution demonstrated the highest sensitivity of 100% in predicting the mecA presence, followed by 72.8% by agar dilution and 70.4% by disk diffusion. The results indicate that broth microdilution may be more suitable for predicting the presence of mecA in CoNS from animals than the other two methods, although staphylococcal species may also be a factor affecting the sensitivities of the methods as the top three staphylococcal species in this study were Staphylococcus lentus, Staphylococcus sciuri, and Staphylococcus xylosus (a total of 75 of 87).

  6. Contribution of the Kallikrein/Kinin System to the Mediation of ConA-Induced Inflammatory Ascites.

    Intraperitoneal administration of concanavalin A (ConA, 25 mg/kg b.w.), a cell-binding plant lectin was used for inducing inflammatory ascites, and potential inhibitors were tested in 1 h and 2.5 h experiments, i.e. still before the major influx of leucocytes. At the end of the experiment the peritoneal fluid was collected and measured. The ConA-induced ascites was significantly (p<0.01) and dose-dependently inhibited by icatibant (HOE-140), a synthetic polypeptide antagonist of bradykinin receptors. Aprotinin, a kallikrein inhibitor protein also had significant (p<0.01), but less marked inhibitory effect. L-NAME, an inhibitor of NO synthesis, and atropine methylnitrate, an anticholinergic compound, were ineffective. It is concluded, that the kallikrein/kinin system contributes to the mediation of the ConA-induced ascites by increasing subperitoneal vascular permeability, independent of the eventual vasodilation produced by NO. It is known, that membrane glycoproteins are aggregated by the tetravalent ConA and the resulting distortion of membrane structure may explain the activation of the labile prekallikrein. Complete inhibition of the ConA-induced ascites could not be achieved by aprotinin or icatibant, which indicates the involvement of additional mediators.

    Introducción: Se han encontrado diferencias en los valores de incidencia de osteoporosis y fracturas relacionadas entre los países de la Unión Europea, siendo menor en los países de la zona mediterránea. Este hecho se atribuye principalmente a un patrón de alimentación específica común. La dieta mediterránea contiene un complejo conjunto de componentes bioactivos con propiedades antioxidantes, anti-inflamatorias y alcalinizantes que pueden contribuir al efecto de esta dieta en la salud ósea. Objetivo: El propósito de esta revisión es examinar la evidencia hasta la fecha sobre los efectos de la dieta mediterránea sobre la salud ósea. Métodos: Se realizó una búsqueda en la literatura científica utilizando las siguientes base de datos: PubMed, Scopus and Web of Science. Utilizamos los términos de búsqueda “Dieta Mediterránea”, “adhesión“, “frutas y verduras”, “aceite de oliva“, “pescado” “legumbres”, “cereal”, “alcohol”, “hueso“, “osteoporosis”,”fractura”, y combinaciones, como “Dieta Mediterránea y el hueso“ o “Dieta mediterránea y fracturas“. Resultados: Existe un número limitado de estudios que analicen la relación entre el seguimiento de la Dieta Mediterránea y la salud ósea, mostrando resultados contradictorios. Diversos trabajos han mostrado que la adherencia a una dieta mediterránea tradicional se asociado con una mayor densidad mineral ósea y un menor riesgo de fractura en población adulta. Los resultados de estos estudios podrían atribuirse a un efecto beneficioso combinado de los componentes individuales de la dieta mediterránea. Por el contrario, en otros trabajos no se ha encontrado ninguna asociación entre la adherencia a la dieta mediterránea y los índices de masa ósea. Conclusiones: Se requieren más estudios a gran escala para aclarar el efecto de la dieta mediterránea sobre la salud ósea, con el fin de establecer el papel de la dieta en la prevención de la

    Rheumatoid Arthritis (RA) is an autoimmune chronic disease that is characterized by the positivity of various antibodies, the most specific being autoantibodies against citrullinated antigens (ACPA). Despite ACPA are not arthritogenic by themselves, ACPA positive individuals have high risk of RA development and ACPA positivity is associated with severe erosive phenotype and higher mortality rate compared to seronegative RA. Moreover, ACPA status is associated with favorable response to biologics targeting pathways involving autoantibody producing cells as B lymphocytes. In the current review we have discussed the pros and cons on the available scientific evidences, regarding the diagnostic, prognostic and management implications of ACPAs in RA.

    The new human papillomavirus (HPV) vaccine is a research breakthrough for pediatric/adolescent health to prevent cervical cancer and related morbidity. The annual heath care cost for the treatment of cervical cancer and genital warts is estimated to be more than three billion dollars a year. The new HPV vaccine has incredible potential to improve reproductive health promotion, reduce health care costs, and close health care disparity gaps. However, issues both for and against the new HPV vaccine, including mandating vaccination, high cost of the vaccine, the short duration of protection offered, and the perceived promotion of sexual activity, cause confusion. Pediatric nurses, including those in advanced practice, benefit by understanding the pros and cons of these issues in advocating for their patients.

    Heart failure after myocardial infarction is the leading cause of mortality and morbidity worldwide. Existing medical and interventional therapies can only reduce the loss of cardiomyocytes during myocardial infarction but are unable to replenish the permanent loss of cardiomyocytes after the insult, which contributes to progressive pathological left ventricular remodeling and progressive heart failure. As a result, cell-based therapies using multipotent (adult) stem cells and pluripotent stem cells (embryonic stem cells or induced pluripotent stem cells) have been explored as potential therapeutic approaches to restore cardiac function in heart failure. Nevertheless, the optimal cell type with the best therapeutic efficacy and safety for heart regeneration is still unknown. In this review, the potential pros and cons of different types of multipotent (adult) stem cells and pluripotent stem cells that have been investigated in preclinical and clinical studies are reviewed, and the future perspective of stem cell-based therapy for heart regeneration is discussed.

    2015-01-01

    Biomedical investigators use different methods including experimental animals, tissue, and cell cultures as well as computational simulations and clinical studies finding the ways to treat human diseases and disorders. All the mentioned procedures have their own advantages and disadvantages. For instance although animal models provide some drawbacks like difference in biokinetics parameters or extrapolation of results to human, they are more reliable than in vitro tests. The disadvantage of the in vitro procedures is that they are mostly performed on cancerous cell lines that have a substantially abnormal function. Furthermore, although in vitro models are fruitfully used in biological fields, finding an end point, the initial aim of chemical attack, and extrapolation of the effects to the human are some real weaknesses. Absence of biokinetics in in vitro methods may lead to a misinterpretation of the data. The present review has criticized the pros and cons of both methods, especially in the fields of pharmacology, toxicology, and medical sciences.

    Many public health experts, medical research societies, large health organizations and policy makers have expressed concerns about the increased popularity of electronic cigarettes and have pushed for more restrictive measures ranging from complete bans to tight regulations of these products either as medicines or as tobacco products. But these concerns have never been adequately qualified nor quantified. Without judicious assessment and thorough evaluation, regulations may have unintended consequences that can do more damage than good in public health terms. In this article, we will appraise the existing prominent regulatory frameworks for e-cigarettes, namely, general consumer product, medicinal product and tobacco product regulation, to highlight their pros and cons. Moreover, we provide concrete examples of the unintended consequences which may arise from inappropriate regulatory action.

    2006-01-01

    Countless studies and investigations have been performed siding either for or against the implementation of technology in the healthcare setting. This article presents both sides of this debate, with an obvious conclusion that the pros of this debate win. The practice of information technology in the medical domain lags behind its knowledge and discovery by at least 7 years. The key to closing this gap is to show, through various studies, how information technology systems provide decision support to users at the point in time when decisions are needed. What the reader will obtain from this article is that the pros for information technology implementation in healthcare settings weigh much more and have a greater effect than the cons.

    Technical pros and cons are presented for space and terrestrial media for defense-wide long-haul military communications. Defense-wide military space communications include use of leased commercial satellite capability in addition to the government-owned Defense Satellite Communications System (DSCS). The terrestrial communications include use of troposcatter, HF radios, line-of-sight microwave, and metallic and fiber-optic cables. The current usage, capacity, cost, and other attributes of these media are examined. Current trends and future uses of the space and terrestrial media for military communications are discussed. It is concluded that military communications can continue best by using a mix of both space and terrestrial media.

Algunos de estos cuestionamientos son: no representar exactamente la condición humana como modelos, realizar pruebas de toxicidad con grave daño para los animales, alterar su naturaleza mediante modificaciones genéticas, riesgos de la introducción de organismos genéticamente modificados. El uso de animales en investigación para beneficio humano, impone al ser humano la responsabilidad moral de respetarlo, no haciéndoles sufrir innecesariamente, al estar trabajando con seres vivientes y sentientes.

  18. Formación estelar en NGC 6357: viendo a través del polvo con Gemini

    NASA Astrophysics Data System (ADS)

    Bosch, G.; Morrell, N.; Barbá, R.

    Presentamos aquí los primeros resultados de fotometría JHKs obtenidos con Flamingos I en el telescopio Gemini Sur. El mosaico comprendido por tres posiciones adyacentes tomadas a lo largo de varios semestres nos permite caracterizar la población estelar en la zona que presenta una interacción más importante entre las estrellas masivas y la nube molecular que les dió origen. Los diagramas color-magnitud nos permiten identificar numerosas fuentes con exceso infrarrojo, la mayoría de ellas imposible de detectarse en el rango óptico debido a la fuerte absorción del polvo presente en la región. Es altamente probable que la mayoría de estas fuentes con exceso sean protoestrellas, aunque es necesario realizar espectroscopía infrarroja de las mismas para confirmar su naturaleza.

    Introducción: la enfermedad pulmonar obstructiva crónica (EPOC) es un padecimiento común, costoso y prevenible, y la medición de la calidad de vida en los pacientes que la padecen amplía el panorama de los resultados de su atención. El objetivo fue comparar la calidad de vida relacionada a la salud (CVRS) de acuerdo con el grado de severidad de la EPOC. Métodos: estudio descriptivo. Pacientes con diagnóstico de EPOC clasificado por grado de severidad y relacionado con la CVRS evaluada mediante un cuestionario específico. En el análisis estadístico se utilizó chi cuadrada y ANOVA en rangos de acuerdo con el tipo de variables. Se consideró como significativo un valor p = 0.05. Resultados: Se estudiaron 62 pacientes; 61 % fueron mujeres. El cuestionario de CVRS mostró que Actividad fue la dimensión más afectada (65 ± 24 puntos, p < 0.05). En la dimensión Impacto, los grupos con severidad III y IV mostraron mayor afectación que los grupos I y II (p < 0.05). Hubo una correlación directa entre un mayor FEV1 y una mejor CVRS (r2 - 0.544 p < 0.0001). Conclusiones: La CVRS se encuentra significativamente afectada en pacientes con mayores grados de severidad de la EPOC. Los parámetros predictores de una peor CVRS son % FEV1 y el FVC.

    This study examined self-efficacy (confidence to exercise), pros (exercise's advantages), and cons (exercise's disadvantages) as variables associated across the transtheoretical model's six stages of change in 403 Japanese college students. A series of logistic regression analyses were conducted. Results showed that higher pros and lower cons were associated with being in contemplation compared to precontemplation. Lower cons were associated with being in preparation compared to contemplation. Higher self-efficacy was associated with being in action compared to preparation as well as being in maintenance compared to action. Lower cons were associated with being in termination compared to maintenance.

    Coagulase negative Staphylococci (CoNS) are one of the most common bacteria found on human skin and on mucous membranes as a component of normal flora. The presence of CoNS in clinical specimens is frequently associated with an infectious aetiology or contamination. We aimed to evaluate CoNS species distribution and susceptibility patterns in specimens obtained from clinics and hospitals in the Northern area of Jordan. Standard identification methods showed the presence of CoNS in 223 specimens at different local hospitals. Susceptibility testing was performed using 18 antibiotics in accordance with the Clinical and Laboratory Standards Institute (CLSI) recommendations. Staphylococcus epidermidis and S. haemolyticus were found to be the most common species isolated from all specimens representing 122 (54.7%) and 52 (23.4%) of all CoNS species, respectively. Antibiotic susceptibility testing of CoNS species revealed their sensitivity to vancomycin, linozolid, rifampin and nitrofurantin, while showing a highly resistant pattern to ampicillin, penicillin, ceftriaxone, cefazolin, amoxicillin-clavulanic acid and erythromycin. Some variation of the susceptibility pattern of CoNS species were identified in specimens isolated from the ICU and paediatric hospital wards as well as from clinical specimens of urine, blood and catheter tips. The most common CoNS isolates were found to be S. epidermidis and S. haemolyticus with variable percentages according to the specimen source. Moreover, a high susceptibility CoNS to vancomycin, rifampin, and linezolid showed resistance to amoxicillin and penicillin.

    The Alps and their population are particularly vulnerable to geomorphological and hydrological hazards and this problem might be amplified by ongoing climate change. Natural disasters cause severe monetary damage which often leads to the difficult question whether it socially pays to protect settlements at high costs or whether alternatively settlement areas should better be abandoned. By investigations in the Johnsbachtal and the Kleinsölktal (Styria), the interdisciplinary project "Economic and Ethical Consequences of Natural Hazards in Alpine Valleys" (EE-Con), funded by the Austrian Academy of Sciences, seeks to answer the following questions: (1) Are natural hazards and associated damages in fact increasing, and is this due to meteorological triggers, to anthropogenic factors or to internal process dynamics? (2) What is the perception and knowledge of local people, how is risk and risk prevention communicated? (3) What is the respective cost ratio between protection infrastructure, soft measures of adaptation and other options (e.g. reduction of settlement area)? (4) What legitimate claims to compensation do people have, how far does societal responsibility go and where does individual responsibility start if parts of the settlement area had to be abandoned? These questions will be tackled in an interdisciplinary cooperation between geography, economics and normative theory (philosophy). EE-Con will follow broadly the path of risk analysis and risk assessment, focusing on the temporal dimension (past - present - future) with the aim to unravel the history of natural hazards in the areas and to analyse the economic values involved. In the following, natural hazard scenarios for the future (2050 and 2100) will be developed considering the economic consequences. Besides this, the project deals with local knowledge, risk perception and risk communication, which will be investigated via group interviews and stakeholder workshops and be integrated into a human

    US Domestic, International, allied Foreign National Warfighters and Para-Military First Responders (Police, SWAT, Special Operations, Law Enforcement, Government, Security and more) are put in harm's way all the time. To successfully complete their missions and return home safely are the primary goals of these professionals. Tactical product improvements that affect mission effectiveness and solider survivability are pivotal to understanding the past, present and future of Clip-On in-line weapon sights. Clip-On Weapon Sight (WS) technology was deemed an interim solution by the US Government for use until integrated and fused (day/night multi-sensor) Weapon Sights (WSs) were developed/fielded. Clip-On has now become the solution of choice by Users, Warriors, Soldiers and the US Government. SWaP-C (size, weight and power -cost) has been improved through progressive advances in Clip-On Image Intensified (I2), passive thermal, LL-CMOS and fused technology. Clip-On Weapon Sights are now no longer mounting position sensitive. Now they maintain aim point boresight, so they can be used for longer ranges with increased capabilities while utilizing the existing zeroed weapon and daysight optic. Active illuminated low-light level (both analog I2 and digital LL-CMOS) imaging is rightfully a real-world technology, proven to deliver daytime and low-light level identification confidence. Passive thermal imaging is also a real-world technology, proven to deliver daytime, nighttime and all-weather (including dirty battlefield) target detection confidence. Image processing detection algorithms with intelligent analytics provide documented promise to improve confidence by reducing Users, Warriors and Soldiers' work-loads and improving overall system engagement solution outcomes. In order to understand the future of Clip-On in-line weapon sights, addressing pros and cons, this paper starts with an overview of historical weapon sight applications, technologies and stakeholder decisions

    Introducción: La población universitaria se considera un colectivo especialmente vulnerable desde el punto de vista nutricional ya que comienza a responsabilizarse de su alimentación y atraviesa un período crítico en la consolidación de hábitos y conductas alimentarias. Estudios previos ponen en evidencia el alejamiento de patrones alimentarios saludables y la necesidad de desarrollar acciones de educación e intervención nutricional. Objetivos: Analizar hábitos y conductas relacionadas con la alimentación en una población universitaria en Cataluña como punto de partida para desarrollar estrategias efectivas en la promoción de la salud. Metodología: Estudio observacional transversal descriptivo de hábitos alimentarios y conductas relacionadas con la alimentación (consumo de alcohol, tabaco y actividad física) en estudiantes universitarios de Cataluña. Resultados: La comida y la cena en casa resultaron las comidas imprescindibles de los estudiantes encuestados mientras el desayuno y la merienda se omitían aproximadamente en un 20% de los casos. El patrón dietético obtenido se caracterizó por un consumo excesivo de carnes rojas (84%) y un consumo deficiente o muy deficiente de verduras (39,8%), cereales (92,6%) y frutas (73,9%). El consumo de alcohol en general resultó escaso, siendo la cerveza la bebida más consumida y la mayor parte afirmaron también no ser fumadores habituales. Entre los fumadores habituales predominaron las mujeres. Un número considerable de estudiantes acostumbraban a realizar actividad física moderada o intensa tres o más veces a la semana, a pesar de que una proporción similar no suele realizar ningún tipo de actividad física de manera habitual. Discusión y conclusiones: En la población estudiada se detectan conductas alimentarias que se alejan de las recomendaciones de la Dieta Mediterránea: un escaso consumo de frutas y verduras, un aumento en el consumo de productos lácteos y un predominio en el consumo de

    Insects are one of the most successful animal groups on earth. Some insects, such as the silkworm and honeybee, are beneficial to humans, whereas others are notorious pests of crops. At present, the genomes of 38 insects have been sequenced and made publically available. In addition, the transcriptomes of dozens of insects have been sequenced. As gene data rapidly accumulate, constructing the pathway of molecular interactions becomes increasingly important for entomological research. Here, we developed an improved tool, iPathCons, for knowledge-based construction of pathways from the transcriptomes or the official gene sets of genomes. Considering the high evolution diversity in insects, iPathCons uses a voting system for Kyoto Encyclopedia of Genes and Genomes Orthology assignment. Both stand-alone software and a web server of iPathCons are provided. Using iPathCons, we constructed the pathways of molecular interactions of 52 insects, including 37 genome-sequenced and 15 transcriptome-sequenced ones. These pathways are available in the iPathDB, which provides searches, web server, data downloads, etc. This database will be highly useful for the insect research community.

    The removal and/or treatment of contaminated soil is a major problem facing the US DOE. The EG&G Mound Applied Technologies site in Miamisburg, Ohio, has an estimated 1.5 million cubic feet of soils from past disposal and waste burial practices awaiting remediation from plutonium contamination. This amount includes sediment from the Miami-Erie Canal that was contaminated in 1969 following a pipe- rupture accident. Conventional soil washing techniques that use particle separation would generate too large a waste volume to be economically feasible. Therefore, innovative technologies are needed for the cleanup. The ACT*DE*CON process was developed by SELENTEC for washing soils to selectively dissolve and remove heavy metals and radionuclides. ACT*DE*CON chemically dissolves and removes heavy metals and radionuclides from soils and sediments into an aqueous medium. The ACT*DE*CON process uses oxidative carbonate/chelant chemistry to dissolve the contaminant from the sediment and hold the contaminant in solution. The objective of recent work was to document the proves conditions necessary to achieve the Mound-site and regulatory-cleanup goals using the ACT*DE*CON technology.

    CoNS are the most common cause of neonatal late-onset sepsis. Information on the vancomycin pharmacokinetics/pharmacodynamics against CoNS is limited. The aim of this study was to characterize vancomycin pharmacokinetic/pharmacodynamic relationships for CoNS and investigate neonatal optimal dosage regimens. A hollow fibre and a novel rabbit model of neonatal central line-associated bloodstream CoNS infections were developed. The results were then bridged to neonates by use of population pharmacokinetic techniques and Monte Carlo simulations. There was a dose-dependent reduction in the total bacterial population and C-reactive protein levels. The AUC/MIC and Cmax/MIC ratios were strongly linked with total and mutant resistant cell kill. Maximal amplification of resistance was observed in vitro at an fAUC/MIC of 200 mg · h/L. Simulations predicted that neonates <29 weeks post-menstrual age are underdosed with standard regimens with respect to older age groups. The AUC/MIC and Cmax/MIC ratios are the pharmacodynamic indices that best explain total and resistant cell kill in CoNS infection. This suggests that less-fractionated regimens are appropriate for clinical use and continuous infusions may be associated with increased risk of emergence of antimicrobial resistance. This study has provided the pharmacodynamic evidence to inform an optimized neonatal dosage regimen to take into a randomized controlled trial. © The Author 2016.

    Resumen La investigación tuvo como propósito estimar la prevalencia del Trastorno por Déficit de Atención con Hiperactividad (TDAH) en Costa Rica y determinar si la versión en español del cuestionario Swanson Nolan and Pelham Scale IV (SNAP-IV) es un instrumento de tamizaje útil en una población de niños y niñas escolares costarricenses. El instrumento fue entregado a padres y maestros de 425 niños entre 5 y 13 años de edad (promedio = 8.8). Todos fueron evaluados con el instrumento Swanson, Kotkin, Agler, M-Flynn and Pelham Scale (SKAMP). Su diagnóstico fue confirmado con una entrevista clínica. La sensibilidad y la especificidad del SNAP-IV fueron evaluadas como predictores de criterios de diagnóstico según el DSM-IV. La prevalencia puntual en la muestra del TDAH fue del 5%. El tamizaje más preciso lo hizo el SNAP-IV completado por el maestro en un corte de 20%, con una sensibilidad de 96% y una especificidad de un 82%. La sensibilidad de los instrumentos completados por los padres fue más baja que aquella de los maestros. El SNAP-IV completado por las maestras con un corte aislando el 20% de los mayores puntajes categorizó correctamente a un 87% de los sujetos. PMID:22432094

  10. Synthesis of colloidal metal nanocrystals in droplet reactors: the pros and cons of interfacial adsorption.

    2014-07-09

    Droplet reactors have received considerable attention in recent years as an alternative route to the synthesis and potentially high-volume production of colloidal metal nanocrystals. Interfacial adsorption will immediately become an important issue to address when one seeks to translate a nanocrystal synthesis from batch reactors to droplet reactors due to the involvement of higher surface-to-volume ratios for the droplets and the fact that nanocrystals tend to be concentrated at the water-oil interface. Here we report a systematic study to compare the pros and cons of interfacial adsorption of metal nanocrystals during their synthesis in droplet reactors. On the one hand, interfacial adsorption can be used to generate nanocrystals with asymmetric shapes or structures, including one-sixth-truncated Ag octahedra and Au-Ag nanocups. On the other hand, interfacial adsorption has to be mitigated to obtain nanocrystals with uniform sizes and controlled shapes. We confirmed that Triton X-100, a nonionic surfactant, could effectively alleviate interfacial adsorption while imposing no impact on the capping agent typically needed for a shape-controlled synthesis. With the introduction of a proper surfactant, droplet reactors offer an attractive platform for the continuous production of colloidal metal nanocrystals.

  11. Thromboprophylaxis in carriers of antiphospholipid antibodies (APL) without previous thrombosis: "Pros" and "Cons".

    The presence of anti-phospholipid (aPL) is necessary but not sufficient to induce a thrombotic event. The "second hit" hypothesis suggested that an additional trigger may be needed to develop a vascular event in aPL carriers. In this article, pro and con of primary thromboprophylaxis in aPL carriers is deeply discussed, concluding that univocal data are not available, due to conflicting results of available clinical trials. However, in clinical practice the primary thromboprophylaxis is not indicated in all unselected asymptomatic aPL carriers, and the best strategy begin with the assessment of the peculiar risk profile of the subject. Thus, it is mandatory to eliminate modifiable prothrombotic risk factors (i.e. smoking, oral contraceptive), to treat the irreversible risk factors (i.e. hypertension, diabetes) and to introduce an aggressive prophylaxis with subcutaneous LMWH in high-risk situations (i.e. surgical procedures with prolonged immobilization). A different evaluation should be addressed to aPL carriers with a concomitant autoimmune disease that are considered as an additional pro-thrombotic risk factor. Similarly, concomitant positivity for more than one anti-phospholipid test confer a stronger risk of developing the thrombotic manifestations. Specific trials with larger cohorts of patients are needed to better clarify this issue.

    The anaesthetic conserving device (ACD) AnaConDa(®) was developed to allow the reduced use of inhaled agents by conserving exhaled agent and allowing rebreathing. Elevated has been observed in patients when using this ACD, despite tidal volume compensation for the larger apparatus dead space. The aim of the present study was to determine whether CO(2), like inhaled anaesthetics, adsorbs to the ACD during expiration and returns to a test lung during the following inspiration. The ACD was attached to an experimental test lung. Apparent dead space by the single-breath test for CO(2) and the amount of CO(2) adsorbed to the carbon filter of the ACD was measured with infrared spectrometry. Apparent dead space was 230 ml larger using the ACD compared with a conventional heat and moisture exchanger (internal volumes 100 and 50 ml, respectively). Varying CO(2) flux to the test lung (85-375 ml min(-1)) did not change the measured dead space nor did varying respiratory rate (12-24 bpm). The ACD contained 3.3 times more CO(2) than the predicted amount present in its internal volume of 100 ml. Our measurements show a CO(2) reservoir effect of 180 ml in excess of the ACD internal volume. This is due to adsorption of CO(2) in the ACD during expiration and return of CO(2) during the following inspiration.

    We report on the efficacy of Communicating Science 2013, a science communication workshop for graduate students. Effective science communication is imperative for the sharing of scientific ideas, continued funding and support from policy makers, and education of the public. Science graduate students are a prime group to target for communication training, as they will be our future scientists, educators, and EPO professionals. To this end, Communicating Science 2013 (ComSciCon), a workshop organized by and for STEM graduate students, was held in June of this year. This workshop taught graduate students from around the nation to effectively communicate science to both their peers and the public. To learn about grad students' attitudes toward science communication and establish the workshop's efficacy, we surveyed the participants both before and after the workshop. This assessment probed topics such as communication preparation the participants have already received, how science communication is perceived in their home department, and what participants gained from the workshop. We report the results here.

    Preventive bacille Calmette-Guérin (BCG) vaccination, together with case finding and effective chemotherapy, has formed an integral part of the tuberculosis (TB) control program in most countries. In some low-incidence countries the balance of prevention has been more on the side of chemoprophylaxis than of BCG vaccination. The time clearly has come when the strategy of mass BCG vaccination no longer is indicated medically, nor is it cost-effective. The pros and cons of the programs need to be critically evaluated against the present epidemiological background, taking into account the facts that TB, the killer disease, is recovering strength, human immunodeficiency virus infection is on the increase, and multidrug-resistant TB has changed the outcome of this previously fully curable disease. Although no longer appropriate for mass programs, BCG vaccination still should be considered for the protection of selected risk groups in low-incidence countries. The overall efficacy may be of the order 50% to 80%, but the variation is great. Therefore, further research urgently is needed on the effectiveness of BCG as an intervention in local TB programs.

    Geochemical mapping successfully met a range of needs from mineral exploration to environmental management. In Europe and around the world numerous geochemical datasets already exist. These datasets may originate from geochemical mapping projects or from the collection of sample analyses requested by environmental protection regulatory bodies. Combining datasets can be highly beneficial for establishing geochemical maps with increased resolution and/or coverage area. However this practice requires assessing the equivalence between datasets and, if needed, applying data leveling to remove possible biases between datasets. In the literature, several procedures for assessing dataset equivalence and leveling data are proposed. Daneshfar & Cameron (1998) proposed a method for the leveling of two adjacent datasets while Pereira et al. (2016) proposed two methods for the leveling of datasets that contain records located within the same geographical area. Each discussed method requires its own set of assumptions (underlying populations of data, spatial distribution of data, etc.). Here we propose to discuss the scope of application, pros, cons and practical recommendations for each method. This work is illustrated with several case studies in Wallonia (Southern Belgium) and in Europe involving trace element geochemical datasets. References: Daneshfar, B. & Cameron, E.

    Camine Con Gusto (CCG) is the Hispanic version of an evidence-based walking program for people with arthritis. This study examined CCG outcomes, feasibility, tolerability, safety, and acceptability and potential tailoring. A pre and post 6-week evaluation was conducted in Hispanic people with arthritis. Outcomes included pain, stiffness, fatigue, functional capacity, helplessness, and self-efficacy. A formative evaluation with program participants and key stakeholders explored program tailoring. Participants' mean age was 46.9 years, 44.4% had a high school degree or less, 2.5% were born in United States, 60.1% spoke only Spanish, and 74.7% were female. Moderate effect sizes were found: 0.50 for pain, 0.75 for fatigue, 0.49 for stiffness, 0.33 for function, 0.26 for helplessness, and 0.24 for self-efficacy. There were 285 participants recruited with an 82% 6-week retention (feasibility), no adverse events were reported (safety), and 98% reported program satisfaction (acceptability). Recommended adaptations included simpler language, more pictures and content addressing nutrition and chronic conditions, shortened materials, and inclusion of motivational strategies. CCG showed improvement in outcomes in Hispanic individuals comparable to those noted in non-Hispanic White and Black individuals with arthritis. © The Author(s) 2016.

    2016-01-13

    The diagnostic phenotype of nonalcoholic fatty liver disease (NAFLD)--in particular, the most significant form in terms of prognosis, nonalcoholic steatohepatitis (NASH)--continues to rely on liver tissue evaluation, in spite of remarkable advances in non-invasive algorithms developed from serum-based tests and imaging-based or sonographically-based tests for fibrosis or liver stiffness. The most common tissue evaluation remains percutaneous liver biopsy; considerations given to the needle size and the location of the biopsy have the potential to yield the most representative tissue for evaluation. The pathologist's efforts are directed to not only global diagnosis, but also assessment of severity of injury. Just as in other forms of chronic liver disease, these assessments can be divided into necroinflammatory activity, and fibrosis with parenchymal remodeling, in order to separately analyze potentially reversible (grade) and non-reversible (stage) lesions. These concepts formed the bases for current methods of evaluating the lesions that collectively comprise the phenotypic spectra of NAFLD. Four extant methods have specific applications; there are pros and cons to each, and this forms the basis of the review.

    The aim of this commentary is to balance the pros and cons for pre-surgical SSA treatment in a modern perspective ending up with a pragmatic recommendation for treatment based on the current evidence and expertise of the authors. Even though prospective and randomized studies in this particular area are hampered by obvious limitations, the interpretation of the four published trials has in general been in favor of pre-treatment with SSA, showing a better outcome following surgery. However, major drawbacks of these studies, such as non-optimal diagnostic criteria for cure, potential selection bias, and timing of the postoperative evaluation in SSA pre-treated patients, limit their overall interpretation. Three matched-controlled studies showed remarkably similar results with no apparent beneficial effect of SSA pre-treatment on surgical outcome. Both prospective, randomized studies and retrospective studies did not find any significant difference in the rate of endocrine and non-endocrine complications related to surgery, despite the beneficial clinical effects of SSA treatment in most acromegalic patients. The newly diagnosed patient with acromegaly should be carefully evaluated in the trans-disciplinary neuroendocrine team and treatment individualized accordingly. The issue of SSA pre-treatment to improve surgical outcome is yet to be settled and further methodologically sound studies are probably necessary to clarify this point.

    To examine initiation, pros and cons of hookah tobacco smoking among Arab Americans. In this descriptive cross-sectional study, we recruited a community-based convenience sample of 458 adult Arab-American hookah smokers, mean age 28.4 years, who completed self-administered questionnaires. Irrespective of sex, most participants initiated hookah tobacco use by young adulthood in private homes or hookah lounges influenced by friends and family. Women initiated hookah use later than men. Ever dual smokers (hookah smokers who ever smoked a cigarette) initiated hookah use later than cigarettes; however, early hookah initiators < 18 years initiated hookah and cigarettes concurrently. Participants enjoyed the flavors of hookah tobacco, and complained about coughing, dizziness, and headaches. Early and late initiation of hookah tobacco use warrant prevention programs targeting the youth and older adults in communities, colleges, and middle and high schools that include health education campaigns, and encouragement of voluntary smokefree home rules. Tobacco control policies aimed to prevent initiation of hookah use should include regulation of hookah tobacco flavors, and should target the physical environments in neighborhoods, especially around schools and colleges, to reduce the proliferation of hookah lounges. Dual hookah tobacco and cigarette use warrant continuous monitoring.

A total of 241 self-identified gay and bisexual men responded to the questionnaire in a 3-month period of time. Confidentiality was assured by utilizing an electronic system whereby the respondents e-mail address was eliminated. The study was conceptually guided by the use of the Transtheoretical Model of Behavioral Change (TMC) and the pros and cons of condom of use were explored. Fifty-six percent of the participants reported that one advantage (pro) of using condoms with casual partners was that it would make them safer from disease. About half of the respondents (n = 119, 49%) reported a history of one or more sexually transmitted diseases. There were 14 variables found to be significantly associated with using a condom with primary and casual partners among gay and bisexual men. Essentially, findings from this study corresponded to results obtained by more traditional data collection methods. Therefore, the authors conclude that electronic data collection may well be an alternative means for collecting sensitive data such as those collected in this study.

    Coating of liposomes with polyethylene-glycol (PEG) by incorporation in the liposome bilayer of PEG-derivatized lipids results in inhibition of liposome uptake by the reticulo-endothelial system and significant prolongation of liposome residence time in the blood stream. Parallel developments in drug loading technology have improved the efficiency and stability of drug entrapment in liposomes, particularly with regard to cationic amphiphiles such as anthracyclines. An example of this new generation of liposomes is a formulation of pegylated liposomal doxorubicin known as Doxil or Caelyx, whose clinical pharmacokinetic profile is characterized by slow plasma clearance and small volume of distribution. A hallmark of these long-circulating liposomal drug carriers is their enhanced accumulation in tumors. The mechanism underlying this passive targeting effect is the phenomenon known as enhanced permeability and retention (EPR) which has been described in a broad variety of experimental tumor types. Further to the passive targeting effect, the liposome drug delivery platform offers the possibility of grafting tumor-specific ligands on the liposome membrane for active targeting to tumor cells, and potentially intracellular drug delivery. The pros and cons of the liposome platform in cancer targeting are discussed vis-à-vis nontargeted drugs, using as an example a liposome drug delivery system targeted to the folate receptor.

    Assessment of ocular irritation is a regulatory requirement in safety evaluation of industrial and consumer products. Although a number of in vitro ocular irritation assays exist, none are capable of fully categorizing chemicals as stand-alone assays. Therefore, the CEFIC-LRI-AIMT6-VITO CON4EI (CONsortium for in vitro Eye Irritation testing strategy) project was developed to assess the reliability of eight in vitro test methods and computational models as well as establishing an optimal tiered-testing strategy. For three computational models (Toxtree, and Case Ultra EYE_DRAIZE and EYE_IRR) performance parameters were calculated. Coverage ranged from 15 to 58%. Coverage was 2 to 3.4 times higher for liquids than for solids. The lowest number of false positives (5%) was reached with EYE_IRR; this model however also gave a high number of false negatives (46%). The lowest number of false negatives (25%) was seen with Toxtree; for liquids Toxtree predicted the lowest number of false negatives (11%), for solids EYE_DRAIZE did ((78%).It can be concluded that the training sets should be enlarged with high quality data. The tested models are not yet sufficiently powerful for stand-alone evaluations, but that they can surely become of value in an integrated weight-of-evidence approach in hazard assessment.

    Magnetic alloys and multilayers have been widely investigated because of their potential for magnetic device applications. In this, materials exhibiting high magnetization as well as good soft magnetic properties are desirable. We investigated the magnetic and structural properties of Fe_mCon superlattices with various compositions via first principles local density full potential linearized augmented plane wave (FLAPW) method^(1) calculations. For the 25% Co composition which showed the maximum magnetic moments, we inserted N atoms to make (Fe_3Co)_4N_2, in order to examine the possible magnetic enhancement by N, which has drawn much attention since the first report (in 1972) of a giant magnetic moment for the quasi-stable α-Fe_16N_2. The structural optimization was fully accomplished by total energy and atomic force calculations. Despite the lattice expansion due to the N insertion, the magnetic moment of (Fe_3Co)_4N2 was found to be reduced from the value of the Fe_3Co superlattice by the strong hybridization of N with Fe and Co.

    New millimeter-wave transitions of the CO-N2 van der Waals complex have been observed using the intracavity OROTRON jet spectrometer in the frequency range of 103-159 GHz. For the less abundant form, CO-paraN2, a total of 37 rotational transitions were assigned to three K = 0-0, 0-1, 2-1 subbands connecting the (jCO, jN2) = (1, 1) and (jCO, jN2) = (0, 1) internal rotor states. The upper K = 0 and K = 2 "stacks" of rotational levels were probed for the first time here by millimeter-wave spectroscopy following a recent infrared study by Rezaei et al. (2013). The observation of new subbands fixes with higher precision not only these upper K = 0 and K = 2 but also lower K = 1(f) levels, not linked with other stacks in earlier rotational studies. For the more abundant form, CO-orthoN2, five new P-branch rotational transitions of the K = 0-0 "CO bending" subband are reported, thus extending previous measurements. Nuclear quadrupole hyperfine structure due to the presence of two equivalent 14N nuclei was partly resolved and analyzed to give additional information about the angular orientation of the N2 molecule in the complex.

    The lowest-lying X1Sigma+, a3Phi, b3II, c5Delta, A1Phi, and B1II electronic states of CoN have been investigated at the ab initio MRCI and MS-CASPT2 levels, with extended atomic basis sets and inclusion of scalar relativistic effects. Among the singlet states, the A1Phi and B1II states have been described for the first time. Potential energy curves, excitation energies, spectroscopic constants, and bonding character for all states are reported. Comparison with other early transition-metal nitrides (ScN, TiN, VN, and CrN), isoelectronic (NiC) and isovalent (RhN and IrN) species has been made, besides analyzing the B1II <=> X1+ electronic transition in terms of Franck-Condon factors, Einstein coefficients, and radiative lifetimes. At both levels of theory, the following energetic order has been obtained: X1Sigma+, a3Phi, b3II, c5Delta, A1Phi, and B1II, with good agreement with experimental results. In contrast, previous DFT and MRCI calculations predicted the ground state to be the 5Delta state.

    Autophagy, a self-eating machinery, has been reported as an adaptive response to maintain metabolic homeostasis when cancer cells encounter stress. It has been appreciated that autophagy acts as a double-edge sword to decide the fate of cancer cells upon stress factors, molecular subtypes, and microenvironmental conditions. Currently, the majority of evidence support that autophagy in cancer cells is a vital mechanism bringing on resistance to current and prospective treatments, yet whether autophagy affects the anticancer immune response remains unclear and controversial. Accumulated studies have demonstrated that triggering autophagy is able to facilitate anticancer immunity due to an increase in immunogenicity, whereas other studies suggested that autophagy is likely to disarm anticancer immunity mediated by cytotoxic T cells and nature killer (NK) cells. Hence, this contradiction needs to be elucidated. In this review, we discuss the role of autophagy in cancer cells per se and in cancer microenvironment as well as its dual regulatory roles in immune surveillance through modulating presentation of tumor antigens, development of immune cells, and expression of immune checkpoints. We further focus on emerging roles of autophagy induced by current treatments and its impact on anticancer immune response, and illustrate the pros and cons of utilizing autophagy in cancer immunotherapy based on preclinical references.

  7. Pro/Con debate: Is occupational asthma induced by isocyanates an immunoglobulin E-mediated disease?

    Isocyanates, low-molecular weight chemicals essential to polyurethane production, are one of the most common causes of occupational asthma, yet the mechanisms by which exposure leads to disease remain unclear. While isocyanate asthma closely mirrors other Type I Immune Hypersensitivity (Allergic) disorders, one important characteristic of hypersensitivity ('allergen'-specific IgE) is reportedly absent in a large portion of affected individuals. This variation from common environmental asthma (which typically is induced by high-molecular weight allergens) is important for two reasons. (1) Allergen-specific IgE is an important mediator of many of the symptoms of bronchial hyper-reactivity in 'allergic asthma'. Lack of allergen-specific IgE in isocyanate hypersensitive individuals suggests differences in pathogenic mechanisms, with potentially unique targets for prevention and therapy. (2) Allergen-specific IgE forms the basis of the most commonly used diagnostic tests for hypersensitivity (skin prick and RAST). Without allergen-specific IgE, isocyanates may go unrecognized as the cause of asthma. In hypersensitive individuals, chronic exposure can lead to bronchial hyperreactivity that persists years after exposure ceases. Thus, the question of whether or not isocyanate asthma is an IgE-mediated disease, has important implications for disease screening/surveillance, diagnosis, treatment and prevention. The present Pro/Con Debate, addresses contemporary, controversial issues regarding IgE in isocyanate asthma.

    Introducción: Los trastornos del comportamiento alimentario (TCA) son las patologías psicológicas que más se han incrementado en los últimos años. Uno de los factores que determina la elevada prevalencia de TCA en nuestra sociedad es el gran desconocimiento sobre alimentación. Este desconocimiento puede deberse a la consulta de recursos online sin validez científica. Objetivo y ámbito: El objetivo de este trabajo ha sido analizar la calidad científica y el posicionamiento de los sitios web en español con información sobre nutrición, TCA y obesidad. Material y métodos: Se realizó una búsqueda de páginas web en el navegador Google Chrome con las palabras clave: dieta, anorexia, bulimia, nutrición y obesidad, seleccionándose los 20 primeros resultados de cada búsqueda según los índices de posicionamiento ofrecidos por SEOquake (Page Rank, Alexa Rank y SEMrush Rank). Las variables de análisis fueron: información relacionada con dietas y hábitos alimentarios, información sobre alimentación saludable, información sobre TCA y sus criterios diagnósticos e información de carácter formativo acerca de temas profesionales de salud general. Resultados: Sólo el 50% de las web encontradas cumplían los criterios de inclusión en el estudio. La mayoría no seguían las pautas establecidas por e-Europa sobre calidad. La mediana de Page Rank fue de 2, excepto en aquellas asociadas a instituciones sanitarias de prestigio. Conclusiones: Dada la escasez de webs sanitarias con rigor científico, es imprescindible la revisión de las existentes y la creación de nuevos espacios on-line cuya supervisión sea realizada por profesionales especialistas en salud y nutrición.

    Objetivo: El objetivo del estudio comprendía visualizar y cuantificar las alteraciones patológicas de la zona avascular foveal (ZAF) mediante angio-OCT en ojos con oclusión venosa de la retina (OVR) en comparación con el ojo contralateral sano. Procedimientos: La angio-OCT se llevó a cabo mediante el sistema Avanti® RTVue 100 XR (Optovue Inc., Fremont, Calif., EE. UU.). Los bordes de la capa vascular superficial (CVS) se definieron como 3 μm por debajo de la membrana limitante interna y 15 μm por debajo de la capa plexiforme interna y, para la capa vascular profunda (CVP), como 15 y 70 μm por debajo de la membrana limitante interna y de la capa plexiforme interna, respectivamente. La longitud de la ZAF horizontal, vertical y máxima de la CVS y la CVP en cada ojo se midió de forma manual. Además, se midió el ángulo entre el diámetro máximo de la ZAF y el plano papilomacular. Resultados: La angio-OCT representó los defectos dentro de la vasculatura en el área perifoveal en ojos con oclusión de rama venosa de la retina (ORVR; n = 11) y con oclusión de la vena central de la retina (OVCR; n = 8). Esto resultó en un crecimiento del diámetro máximo de la ZAF en ojos con OVR (n = 19) en comparación con el ojo contralateral (n = 19; 921 ± 213 frente a 724 ± 145 µm; p = 0,008). Además, se observó una correlación significativa entre la mejor agudeza visual corregida (MAVC) y el diámetro máximo de la ZAF en la CVP (ρ de Spearman = -0,423, p < 0,01). Por último, en los ojos con OVR, el ángulo entre el plano papilomacular y el diámetro máximo de la ZAF se dio tan solo en el 21,05% (CVS) y en el 15,79% (CVP) de los casos a 0 ± 15 ó 90 ± 15°, respectivamente. En ojos sanos, estos ángulos (que supuestamente representan una configuración de la ZAF regular) fueron más prevalentes (CVS 68,42 frente a 21,05%, p = 0,003; CVP 73,68 frente a 15,79%, p < 0,001).

    Jack bean (JB, Canavalia ensiformis) is the source of bio-based products, such as proteins and bio-sugars that contribute to modern molecular biology and biomedical research. In this study, the use of jack bean was evaluated as a source for concanavalin A (Con A) and bio-sugar production. A novel method for purifying Con A from JBs was successfully developed using a glucosylated magnetic nano matrix (GMNM) as a physical support, which facilitated easy separation and purification of Con A. In addition, the enzymatic conversion rate of 2% (w/v) Con A extracted residue to bio-sugar was 98.4%. Therefore, this new approach for the production of Con A and bio-sugar is potentially useful for obtaining bio-based products from jack bean.

    The Phoenix ComiCon (PCC) is a rapidly growing annual four-day pop culture event, featuring guests, costuming, exhibits, and discussion panels for popular sci-fi, fantasy, horror, and anime franchises. In 2013, PCC began experimenting with science discussion panels. The popularity of the science programming resulted in an expansion of the track for 2014, which Horodyskyj was responsible for coordinating. Thirty hours of programming were scheduled, including 25 discussion panels, NASA's FameLab, and a Mars room. Panelists included industry specialists, established scientists, STEM outreach enthusiasts, and early career scientists. The majority of the panelists were early career scientists recruited from planetary sciences and biology departments at ASU and UA. Panel topics included cosmology, biotechnology, artificial intelligence, space exploration, astrobiology, and the cross-linkages of each with pop culture. Formats consisted of Q&A, presentations, and interactive game shows. Although most panels were aimed at the general audience, some panels were more specialized. PCC 2014 attracted 77,818 attendees. The science programming received rave reviews from the audience, the PCC management, and the panelists themselves. Many panel rooms were filled to capacity and required crowd control to limit attendance. We observed the formation of science "groupies" who sought out the science panels exclusively and requested more information on other science public events in the Phoenix area. We distributed surveys to several select sessions to evaluate audience reasons for attending the science panels and their opinion of the scientists they observed. We will present the results of these surveys. As the PCC continues to grow at an exponential rate, the science programming will continue to expand. We will discuss ideas for continued expansion of the PCC science programming both to serve the public and as a unique public outreach opportunity for early career scientists.

    Reading deficits are a common early feature of the degenerative syndrome posterior cortical atrophy (PCA) but are poorly understood even at the single word level. The current study evaluated the reading accuracy and speed of 26 PCA patients, 17 typical Alzheimer's disease (tAD) patients and 14 healthy controls on a corpus of 192 single words in which the following perceptual properties were manipulated systematically: inter-letter spacing, font size, length, font type, case and confusability. PCA reading was significantly less accurate and slower than tAD patients and controls, with performance significantly adversely affected by increased letter spacing, size, length and font (cursive < non-cursive), and characterised by visual errors (69% of all error responses). By contrast, tAD and control accuracy rates were at or near ceiling, letter spacing was the only perceptual factor to influence reading speed in the same direction as controls, and, in contrast to PCA patients, control reading was faster for larger font sizes. The inverse size effect in PCA (less accurate reading of large than small font size print) was associated with lower grey matter volume in the right superior parietal lobule. Reading accuracy was associated with impairments of early visual (especially crowding), visuoperceptual and visuospatial processes. However, these deficits were not causally related to a universal impairment of reading as some patients showed preserved reading for small, unspaced words despite grave visual deficits. Rather, the impact of specific types of visual dysfunction on reading was found to be (con)text specific, being particularly evident for large, spaced, lengthy words. These findings improve the characterisation of dyslexia in PCA, shed light on the causative and associative factors, and provide clear direction for the development of reading aids and strategies to maximise and sustain reading ability in the early stages of disease.

  16. Iliac crest autograft versus alternative constructs for anterior cervical spine surgery: Pros, cons, and costs

    PubMed Central

    Epstein, Nancy E.

    2012-01-01

    Background: Grafting choices available for performing anterior cervical diskectomy/fusion (ACDF) procedures have become a major concern for spinal surgeons, and their institutions. The “gold standard”, iliac crest autograft, may still be the best and least expensive grafting option; it deserves to be reassessed along with the pros, cons, and costs for alternative grafts/spacers. Methods: Although single or multilevel ACDF have utilized iliac crest autograft for decades, the implant industry now offers multiple alternative grafting and spacer devices; (allografts, cages, polyether-etherketone (PEEK) amongst others). While most studies have focused on fusion rates and clinical outcomes following ACDF, few have analyzed the “value-added” of these various constructs (e.g. safety/efficacy, risks/complications, costs). Results: The majority of studies document 95%-100% fusion rates when iliac crest autograft is utilized to perform single level ACDF (X-ray or CT confirmed at 6-12 postoperative months). Although many allograft studies similarly quote 90%-100% fusion rates (X-ray alone confirmed at 6-12 postoperative months), a recent “post hoc analysis of data from a prospective multicenter trial” (Riew KD et. al., CSRS Abstract Dec. 2011; unpublished) revealed a much higher delayed fusion rate using allografts at one year 55.7%, 2 years 87%, and four years 92%. Conclusion: Iliac crest autograft utilized for single or multilevel ACDF is associated with the highest fusion, lowest complication rates, and significantly lower costs compared with allograft, cages, PEEK, or other grafts. As spinal surgeons and institutions become more cost conscious, we will have to account for the “value added” of these increasingly expensive graft constructs. PMID:22905321

    Development of the pros and cons of intraperitoneal (IP) chemotherapy in the treatment of epithelial ovarian cancer based on the most prominent data published on the evolution of IP chemotherapy and on experience with this therapeutic strategy in clinical routine. The literature published on IP chemotherapy in ovarian cancer between 1970 and 2008 was identified systematically by computer-based searches in MEDLINE and the Cochrane Library. Furthermore, a preliminary analysis of data recorded during an observational nationwide multicenter study of the Austrian AGO on IP-IV chemotherapy using the GOG-172 treatment regimen was performed. The literature review unequivocally revealed a significantly greater toxicity for IP than for intravenous (IV) cisplatin-based chemotherapy. However, according to a Cochrane meta-analysis, IP-IV administration of chemotherapy is associated with a 21.6% decrease in the risk for death. In agreement with earlier reports, the most frequently mentioned side-effects in the Austria-wide observational study were long-lasting neurotoxicity, abdominal pain, fatigue, gastrointestinal and metabolic toxicities, and catheter-related complications. Most of these toxicities were identified as mirroring the toxicity profile of high-dose IV cisplatin (>or=100 mg/m(2)). In some patients, the classic IP-IV regimen with cisplatin/paclitaxel was changed to an alternative schedule comprising carboplatin AUC 5 (d1) and weekly paclitaxel 60 mg/m(2) (d1, 8, 15) completely administered via the IP route. This treatment was better tolerated and quality of life was significantly less compromised. However, neutropenia and thrombocytopenia were the limiting side-effects of this IP regimen.

    The authors present their own experience concerning total hip arthroplasty with the metaphyseal prosthesis Proxima. Proxima, a metaphyseal prosthesis, provides an innovative supplement to total hip arthroplasty. In this study, the authors present their own experience using Proxima in patients with hip osteoarthritis. This study was performed between 2008 to 2013 and comprised of 62 patients, of which 38 were male (61.3%) and 24 female (38.7%). All patients were operated on due to hip osteoarthritis using total hip arthroplasty with the metaphyseal prosthesis Proxima. The age of patients included into the study ranged from 23 years to 62 years with the mean age of 46 years. The authors paid close attention to the "pros and cons" of surgical techniques and assessed clinical and radiological results in both the short and long-term observation periods. The clinical evaluation was based on the Harris Hip Score and radiological assessment of fixation of the acetabular cup of the endoprosthesis was based on Pradhan's criteria. The endoprosthesis Proxima stem was positioned using the manufacturer's recommended method, evaluating the direction, scope and duration of the displacement in the marrow cavity of the proximal stump of the femur. According to the authors' analysis, the surgery gives good functional and radiological results both in the short- and long-term observation periods. The effectiveness depends on precise qualification for surgery, proper surgical techniques and specific anatomical conditions of the proximal femur stump. The most common reasons for primary and secondary dislocations of the metaphyseal endoprosthesis Proxima stem occur during the first three months post surgery. This is due to incorrect surgical techniques, which disregard the importance of specific anatomical conditions of the proximal femoral stump, which affects Proxima implantation, and cause deviations towards a varus or valgus orientation.

    This data package contains the K Basin sludge characterization results obtained by Pacific Northwest National Laboratory during processing and analysis of four sludge core samples collected from Engineered Container SCS-CON-210 in 2010 as requested by CH2M Hill Plateau Remediation Company. Sample processing requirements, analytes of interest, detection limits, and quality control sample requirements are defined in the KBC-33786, Rev. 2. The core processing scope included reconstitution of a sludge core sample distributed among four to six 4-L polypropylene bottles into a single container. The reconstituted core sample was then mixed and subsampled to support a variety of characterization activities. Additional core sludge subsamples were combined to prepare a container composite. The container composite was fractionated by wet sieving through a 2,000 micron mesh and a 500-micron mesh sieve. Each sieve fraction was sampled to support a suite of analyses. The core composite analysis scope included density determination, radioisotope analysis, and metals analysis, including the Waste Isolation Pilot Plant Hazardous Waste Facility Permit metals (with the exception of mercury). The container composite analysis included most of the core composite analysis scope plus particle size distribution, particle density, rheology, and crystalline phase identification. A summary of the received samples, core sample reconstitution and subsampling activities, container composite preparation and subsampling activities, physical properties, and analytical results are presented. Supporting data and documentation are provided in the appendices. There were no cases of sample or data loss and all of the available samples and data are reported as required by the Quality Assurance Project Plan/Sampling and Analysis Plan.

However, the approaches used and the methods employed vary, and while such a variability is desirable in terms of scientific diversity, research must adhere to well defined quality standards and reproducible methods OBJECTIVES: With ConSEFS (the Consensus Statement on Ethnopharmacological Field Studies) we want to define best-practice in developing, conducting and reporting field studies focusing on local and traditional uses of medicinal and food plants, including studies using a historical approach. After first developing an initial draft the core group invited community-wide feedback from researchers both through a web-based consultation and a series of workshops at conferences during 2017. The consultation resulted in a large number of responses. Feedback was received via a weblink on the Journal of Ethnopharmacology's website (ca. 100 responses), other oral and written responses (ca. 50) and discussions with stakeholders at four conferences. The main outcome is a checklist, covering best practice for designing, implementing and recording ethnopharmacological field studies and historical studies. Prior to starting ethnopharmacological field research, it is essential that the authors are fully aware of the best practice in the field. For the first time in the field of ethnopharmacology a community-wide document defines guidelines for best practice on how to conduct and report such studies. It will need to be updated and further developed. While the feedback has been based on responses by many experienced researchers, there is a need to test it in practice by using it both in implementing and reporting field studies (or historical studies), and peer-review.

    Boris, N.; Rodriguez-Ardilla, A. A.; Pastoriza, M. G.

    Presentamos imágenes CCD en los filtros BVI y Hα de una muestra de 10 galaxias Seyfert 1 y Narrow Line Seyfert 1. Recientes observaciones muestran que hay una diferencia significante en el índice espectral óptico entre NLS1s y Sy1 normales, siendo para las primeras del orden de 2. Otra característica importante es que la mayor parte de las NLS1s muestran tasas de FeII/Hβ mayores que las observadas en otras Sy1s. Desde el punto de vista fotométrico, estas galaxias no tienenningún tipo de estudio previo. Presentamos magnitudes totales, perfiles de luminosidad y mapas de color junto con un detallado análisis de la formación estelar en estos objetos. Encontramos que la descomposición en bulbo + disco representa adecuadamente los perfiles de luminosidad de las galaxias de la muestra. Sin embargo, en todos los casos es necesario que el disco tenga un agujero en su centro. El radio de este agujero va desde los 3 a los 9 kpc. Si bien no tenemos aún una explicación para este hecho, los agujeros parecen estar asociados a anillos circumnucleares de alto oscurecimiento E(B-V) ~1. Los perfiles presentan también un fuerte gradiente de color, siendo notablemente más azules hacia la región nuclear. Los objetos de la muestra cubren todo el rango de tipos morfológicos, no obstante, no encontramos regiones de formación estelar en las regiones exteriores de las galaxias. La formación estelar está confinada a la región nuclear y se data en alrededor de 5 x 107 años.

    In this study were investigated the surface strain rates computed from the direction variations and velocity values estimated from the coordinates of the continuous monitoring geodetic network called SIRGAS-CON. That investigation was done using points located in the South American plate. The determination of the strain rate was based on the Finite Element method using points defined by Delaunay triangulation (sub-networks). Each one of sub-networks was considered as an homogeneous solid body. Using these methods was possible to separate the strain from the plate movement. The results showed that there are differences of strain rate along the South American plate. From the results were suggest that near to the west board of the plate, the strain is more significant, as expected, because this region is near to one area where Nazca Plate subduct South American Plate. It was detected that the contraction region founded in this area coincides whit the region where occurs most of earthquakes of greater magnitude. Far from the board, there are some areas with anomalies of significant strain of extension and contraction that can be originated by differences of stress aligned with different geological composites. By the results, It may be concluded that large surface movements occur in regions with more heterogeneous geological structures and multiple event of rupture, that large earthquakes arising from large tectonic activity into South American Plate are concentrated in areas with contraction strain rates predominantly oriented towards northeast-southwest, that significant amounts of elastic strain can be accumulated over geological structures away from fault plate boundary and that the behavior of contractions and extensions are similar to that found by different researches involving geophysical studies.

    Resumen Los estereotipos sexuales son creencias generalmente aceptadas y poco cuestionadas que podrían contribuir a cómo los hombres y las mujeres debemos expresar nuestra sexualidad. Los objetivos de este estudio eran identificar cuántos hombres y mujeres heterosexuales en Puerto Rico endosaban ciertos estereotipos acerca de la sexualidad masculina y femenina y explorar la relación entre el endoso de estos estereotipos sexuales y las actitudes hacia el condón masculino y su uso en relaciones sexuales vaginales Llevamos a cabo un estudio descriptivo-correlacional mediante el cual le administramos dos escalas, una sobre sexualidad masculina y otra sobre sexualidad femenina a un grupo de 429 personas heterosexuales. Encontramos que los hombres endosaron estereotipos sexuales masculinos y femeninos más que las mujeres y que estos tienden a tener una visión más conservadora respecto a la sexualidad femenina que la que tienen sobre su propia sexualidad. Las mujeres, por otra parte, tienden a ver su propia sexualidad y la sexualidad masculina en términos menos estereotipados y más equitativos. También encontramos que a mayor endoso de creencias tradicionales sobre la sexualidad masculina y femenina, peor la actitud hacia el uso del condón masculino. Sin embargo, el endosar estereotipos sexuales masculinos y/o femeninos no se relacionó con el uso del condón. Estos hallazgos contradicen la literatura que sugiere que estos estereotipos sexuales y de género resultan en conductas sexuales de alto riesgo, lo cual tiene implicaciones importantes para el desarrollo e implementación de programas de prevención.

    Pollution of water by sewage and run-off from farms produces a serious public health problem in many countries. Viruses, along with bacteria and protozoa in the intestine or in urine are shed and transported through the sewer system. Even in highly industrialized countries, pathogens, including viruses, are prevalent throughout the environment. Molecular methods are used to monitor viral, bacterial, and protozoan pathogens, and to track pathogen- and source-specific markers in the environment. Molecular techniques, specifically polymerase chain reaction-based methods, provide sensitive, rapid, and quantitative analytical tools with which to study such pathogens, including new or emerging strains. These techniques are used to evaluate the microbiological quality of food and water, and to assess the efficiency of virus removal in drinking and wastewater treatment plants. The range of methods available for the application of molecular techniques has increased, and the costs involved have fallen. These developments have allowed the potential standardization and automation of certain techniques. In some cases they facilitate the identification, genotyping, enumeration, viability assessment, and source-tracking of human and animal contamination. Additionally, recent improvements in detection technologies have allowed the simultaneous detection of multiple targets in a single assay. However, the molecular techniques available today and those under development require further refinement in order to be standardized and applicable to a diversity of matrices. Water disinfection treatments may have an effect on the viability of pathogens and the numbers obtained by molecular techniques may overestimate the quantification of infectious microorganisms. The pros and cons of molecular techniques for the detection and quantification of pathogens in water are discussed. (c) 2010 Elsevier Ltd. All rights reserved.

    Patients with a suspicious lung mass sometimes receive surgery with no preoperative tissue diagnosis despite-and sometimes in lieu of-modern medical investigations. The pros and cons of doing so have rarely been studied. Pulmonary surgery was performed in 443 consecutive adult patients with a lung mass confirmed or suspected to be an early stage primary lung cancer. No diagnosis was confirmed preoperatively in 206 (46.5%) patients. Whether to take a core biopsy or wedge excision biopsy for frozen section assessment intraoperatively was decided at the surgeon's discretion. Patients without preoperative diagnosis were on average younger than those with a diagnosis (61 vs 66 years, P < 0.01), but were otherwise similar to those who had a preoperative diagnosis confirmed. In all patients operated on without a preoperative diagnosis, there was no mortality or major complication, and the perioperative minor morbidity rate was 9.7%. Among patients ultimately found to have lung cancer and who received a lobectomy, performing a frozen section intraoperatively did not increase mean operation time or morbidity. Among those patients with no preoperative tissue diagnosis, 97 (47.1%) proceeded to surgery without attempts at preoperative diagnosis, and 109 (52.9%), after attempts at preoperative diagnosis failed to yield a positive diagnosis. After surgery, benign disease was found in 16 (7.8%) patients without preoperative diagnosis. A significantly lower proportion of patients without preoperative diagnosis waited an interval of over 28 days between presentation and being accepted for thoracic surgery (42.2 vs 54.9%, P < 0.01). However, they were not more likely to have Stage I disease and did not have better recurrence-free survival rates on survival analysis. Proceeding to surgery without preoperative diagnosis in selected patients with a suspicious lung mass is safe and can potentially reduce the interval between presentation and surgical management. However, the shortened

    The garnet bearing gneiss within the Day Nui Con Voi (DNCV) Metamorphic Complex along the Red River Shear Zone (RRSZ) in North Vietnam, recorded a long tectonothermal history since the Indosinian orogeny. In-situ 40Ar/39Ar laserprobe study of biotite inclusions within garnet porphyroblasts and matrix biotites, combining with microstructural and scanning electron microscopy (SEM) studies, deciphered the timing and duration of thermal events. Biotites from two matrix fabrics from different deformation events show approximately similar 40Ar/39Ar age ranges in 19-24Ma, depending grain size. These matrix biotite ages are best interpreted to record a rapid cooling event associating with the left-lateral shearing event of the RRSZ. Whereas, all biotite inclusions exhibit age zoning patterns with 40Ar/39Ar ages gradually increase from 17 Ma to more than 28 Ma according to their diffusion pathways. These age variations may have resultant from a combination effect of argon retention by garnet shielding, which provides a best recorder to the metamorphic event, and argon diffusion loss along the deformed cracks during the shearing event of the RRSZ. Diffusion modeling of these age zoning indicated that the total duration of argon diffusion loss may have lasted for nearly 9 Myr and argon diffusion may have occurred sometime around 24.5Ma. These results are generally in good agreement with previous interpretation, but provide better resolution of 40Ar/39Ar age data for deciphering the history of thermal event in the DNCV Metamorphic Complex and the left-lateral shearing event of the RRSZ in Vietnam, as well.

  7. Exploring the pros and cons of mechanistic case diagrams for problem-based learning

    2017-01-01

    Purpose Mechanistic case diagram (MCD) was recommended for increasing the depth of understanding of disease, but with few articles on its specific methods. We address the experience of making MCD in the fullest depth to identify the pros and cons of using MCDs in such ways. Methods During problem-based learning, we gave guidelines of MCD for its mechanistic exploration from subcellular processes to clinical features, being laid out in as much detail as possible. To understand the students’ attitudes and depth of study using MCDs, we analyzed the results of a questionnaire in an open format about experiencing MCDs and examined the resulting products. Results Through the responses to questionnaire, we found several favorable outcomes, major of which was deeper insight and comprehensive understanding of disease facilitated by the process of making well-organized diagram. The main disadvantages of these guidelines were the feeling of too much workload and difficulty of finding mechanisms. Students gave suggestions to overcome these problems: cautious reading of comprehensive texts, additional guidance from staff about depth and focus of mechanisms, and cooperative group work. From the analysis of maps, we recognized there should be allowance of diversities in the appearance of maps and many hypothetical connections, which could be related to an insufficient understanding of mechanisms in nature. Conclusion The more detailed an MCD task is, the better students can become acquainted with deep knowledges. However, this advantage should be balanced by the results that there are many ensuing difficulties for the work and deliberate help plans should be prepared. PMID:28870018

    Introducción: El licopeno es un carotenoide que se encuentra principalmente en el tomate, conserva sus propiedades funcionales después de ser procesado, no presenta toxicidad y posee efectos antioxidantes, antiinflamatorios y quimioterapéuticos sobre las enfermedades cardiovasculares, neurodegenerativas y algunos tipos de cáncer. Sin embargo, parece que su consumo a través de la dieta es insuficiente. Objetivo: El objetivo de la presente revisión es destacar las propiedades del licopeno y las recomendaciones para su aprovechamiento en beneficio de la salud. Métodos: Se realizó la revisión bibliográfica relacionada con el tema a través de la base de datos Pub Med. Resultados: La OMS y los gobiernos nacionales promueven a través de las guías alimentarias el consumo diario de 400 g de frutas y verduras por su contenido en sustancias antioxidantes entre ellas el licopeno. La ingesta de licopeno es muy variada con un consumo promedio entre 5 y 7 mg/día. Esta cifra causa controversia debido a que los diferentes estudios presentan grandes diferencias y no existe una cantidad recomendada, lo que impide hacer comparaciones de nivel nacional e internacional y establecer políticas y estrategias que aseguren su consumo. Conclusión: La ingesta de licopeno puede considerarse como una medida preventiva y terapéutica no farmacológica para diferentes tipos de enfermedades, pero se requiere el trabajo de los profesionales de la nutrición y la salud para incrementar su consumo a través de la educación alimentaria y proponer a partir de los resultados de investigaciones científicas sus niveles de ingesta diaria.

    Health disparities persist despite ongoing efforts. Given the United States' rapidly changing demography and socio-cultural diversity, a paradigm shift in behavioral medicine is needed to advance research and interventions focused on health equity. This paper introduces the ConNECT Framework as a model to link the sciences of behavioral medicine and health equity with the goal of achieving equitable health and outcomes in the twenty-first century. We first evaluate the state of health equity efforts in behavioral medicine science and identify key opportunities to advance the field. We then discuss and present actionable recommendations related to ConNECT's five broad and synergistic principles: (1) Integrating Context; (2) Fostering a Norm of Inclusion; (3) Ensuring Equitable Diffusion of Innovations; (4) Harnessing Communication Technology; and (5) Prioritizing Specialized Training. The framework holds significant promise for furthering health equity and ushering in a new and refreshing era of behavioral medicine science and practice.

    Mammalian protein O-mannosylation, initiated by attachment of α-mannopyranose to Ser or Thr residues, comprise a group of post-translational modifications (PTMs) involved in muscle and brain development. Recent advances in glycoproteomics methodology and the "SimpleCell" strategy have enabled rapid identification of glycoproteins and specific glycosylation sites. Despite the enormous progress made, the biological impact of the mammalian O-mannosyl glycoproteome remains largely unknown to date. Tools are still needed to investigate the structure, role, and abundance of O-mannosyl glycans. Although O-mannosyl branching has been shown to be of relevance in integrin-dependent cell migration, and also plays a role in demyelinating diseases, such as multiple sclerosis, a broader understanding of the biological roles of branched O-mannosyl glycans is lacking in part due to the paucity of detection tools. In this work, a glycopeptide vaccine construct was synthesized and used to generate antibodies against branched O-mannosyl glycans. Glycopeptide microarray screening revealed high selectivity of the induced antibodies for branched glycan core structures presented on different peptide backbones, with no cross-reactivity observed with related linear glycans. For comparison, microarray screening of the mannose-binding lectin concanavalin A (ConA), which is commonly used in glycoproteomics workflows to enrich tryptic O-mannosyl peptides, showed that the ConA lectin did not recognize branched O-mannosyl glycans. The binding preference of ConA for short linear O-mannosyl glycans was rationalized in terms of molecular structure using crystallographic data augmented by molecular modeling. The contrast between the ConA binding specificity and that of the new antibodies indicates a novel role for the antibodies in studies of protein O-mannosylation.

    Recent experimental studies have suggested that proteins fold via stepwise assembly of structural units named 'foldons' through the process of sequential stabilization. Alongside, latest developments on computational side based on probabilistic modeling have shown promising direction to perform de novo protein conformational sampling from continuous space. However, existing computational approaches for de novo protein structure prediction often randomly sample protein conformational space as opposed to experimentally suggested stepwise sampling. Here, we develop a novel generative, probabilistic model that simultaneously captures local structural preferences of backbone and side chain conformational space of polypeptide chains in a united-residue representation and performs experimentally motivated conditional conformational sampling via stepwise synthesis and assembly of foldon units that minimizes a composite physics and knowledge-based energy function for de novo protein structure prediction. The proposed method, UniCon3D, has been found to (i) sample lower energy conformations with higher accuracy than traditional random sampling in a small benchmark of 6 proteins; (ii) perform comparably with the top five automated methods on 30 difficult target domains from the 11th Critical Assessment of Protein Structure Prediction (CASP) experiment and on 15 difficult target domains from the 10th CASP experiment; and (iii) outperform two state-of-the-art approaches and a baseline counterpart of UniCon3D that performs traditional random sampling for protein modeling aided by predicted residue-residue contacts on 45 targets from the 10th edition of CASP.

  18. ConReg-R: Extrapolative recalibration of the empirical distribution of p-values to improve false discovery rate estimates

    PubMed Central

    2011-01-01

    Background False discovery rate (FDR) control is commonly accepted as the most appropriate error control in multiple hypothesis testing problems. The accuracy of FDR estimation depends on the accuracy of the estimation of p-values from each test and validity of the underlying assumptions of the distribution. However, in many practical testing problems such as in genomics, the p-values could be under-estimated or over-estimated for many known or unknown reasons. Consequently, FDR estimation would then be influenced and lose its veracity. Results We propose a new extrapolative method called Constrained Regression Recalibration (ConReg-R) to recalibrate the empirical p-values by modeling their distribution to improve the FDR estimates. Our ConReg-R method is based on the observation that accurately estimated p-values from true null hypotheses follow uniform distribution and the observed distribution of p-values is indeed a mixture of distributions of p-values from true null hypotheses and true alternative hypotheses. Hence, ConReg-R recalibrates the observed p-values so that they exhibit the properties of an ideal empirical p-value distribution. The proportion of true null hypotheses (π0) and FDR are estimated after the recalibration. Conclusions ConReg-R provides an efficient way to improve the FDR estimates. It only requires the p-values from the tests and avoids permutation of the original test data. We demonstrate that the proposed method significantly improves FDR estimation on several gene expression datasets obtained from microarray and RNA-seq experiments.

    Introducción La encefalitis por anticuerpos contra el receptor de N-metil-D-aspartato (NMDA) es una entidad cada vez más diagnosticada en edad pediátrica. A diferencia de los adultos, en muchos casos no se asocia a tumores y las manifestaciones iniciales en niños más frecuentes son crisis convulsivas y trastornos del movimiento, mientras que en los adultos predominan las alteraciones psiquiátricas. Casos clínicos Presentamos seis casos pediátricos confirmados con anticuerpos contra la subunidad NR1 del receptor de NMDA en suero y líquido cefalorraquídeo. Cinco de los casos comenzaron con crisis convulsivas como manifestación clínica inicial antes de desarrollar el cuadro clásico de esta entidad. En todos los casos se utilizaron esteroides como primera línea de tratamiento, con los que sólo se observó control de las manifestaciones en uno, por lo que el resto de los pacientes requirió inmunomoduladores de segunda línea. Todos los pacientes recibieron metotrexato como tratamiento inmunomodulador para evitar recaídas y la evolución fue a la mejoría en todos ellos. Conclusiones En nuestra serie de pacientes con encefalitis por anticuerpos contra el receptor de NMDA, ninguno se asoció a tumores. Todos los casos recibieron metotrexato por lo menos durante un año, no observamos eventos adversos clínicos ni por laboratorio, ni hubo secuelas neurológicas ni recaídas durante el tratamiento. Aunque es una serie pequeña y es deseable incrementar el número y tiempo de evolución, consideramos el metotrexato una excelente alternativa como tratamiento inmunomodulador para esta patología.

    Eukaryotic gene expression is regulated by transcription factors (TFs) binding to promoter as well as distal enhancers. TFs recognize short, but specific binding sites (TFBSs) that are located within the promoter and enhancer regions. Functionally relevant TFBSs are often highly conserved during evolution leaving a strong phylogenetic signal. While multiple sequence alignment (MSA) is a potent tool to detect the phylogenetic signal, the current MSA implementations are optimized to align the maximum number of identical nucleotides. This approach might result in the omission of conserved motifs that contain interchangeable nucleotides such as the ETS motif (IUPAC code: GGAW). Here, we introduce ConBind, a novel method to enhance alignment of short motifs, even if their mutual sequence similarity is only partial. ConBind improves the identification of conserved TFBSs by improving the alignment accuracy of TFBS families within orthologous DNA sequences. Functional validation of the Gfi1b + 13 enhancer reveals that ConBind identifies additional functionally important ETS binding sites that were missed by all other tested alignment tools. In addition to the analysis of known regulatory regions, our web tool is useful for the analysis of TFBSs on so far unknown DNA regions identified through ChIP-sequencing. © The Author(s) 2015.

    El síndrome de anticuerpos antifosfolípidos es una situación clínica y bioquímica heterogénea. Presentamos el caso de un varón joven con antecedente de tromboembolia venosa que se presentó en esta ocasión por dolor precordial, con elevación del ST en el electrocardiograma. Fue llevado a sala de angiografía para realizar angioplastia primaria y se observó una oclusión total ostial de la descendente anterior. Se realizó aspiración manual del trombo. No se realizó angioplastia con balón ni stent. En la angiografía de control a las 48 horas se observó ausencia de trombo y de placas aterosclerosas, lo cual se corroboró mediante ultrasonido intracoronario. Antiphospholipid antibody syndrome is a heterogeneous clinical and biochemical entity. We present the case of a young male with history of venous thromboembolism. This time he presents because of chest ischemic pain associated with ST segment elevation. He was taken to the cath lab to perform a primary percutaneous coronary intervention and a total occlusion of the left anterior descending artery was noted. Successful thrombus aspiration was performed. No stent was deployed. He was taken to the cath lab for a second look angiography and no atherosclerotic lesions were observed, which was confirmed by intravascular ultrasound.

    The structures and electronic properties of CumCon-CO-H2O( m+n=2 -7) clusters have been systematically investigated using density functional theory. The results indicate that the ground-state structures of CumCon-CO-H2O clusters are obtained by adsorbing C atoms of CO and O atoms of H2O on different top sites of stable CumCon clusters. Cu2-CO-H2O, Cu4-CO-H2O, Cu3Co-CO-H2O, Cu4Co-CO-H2O and CuCo4-CO-H2O clusters have relatively stronger thermodynamic stabilities, while Cu2-CO-H2O, Cu4-CO-H2O and Cu6-CO-H2O clusters show stronger chemical stability. H2O molecule doping improves the activation of CO molecules. Mulliken charge and PDOS are also discussed to study the interaction of CO and Cu-Co clusters.

    RIASSUNTO. Scopo. Descrivere il management di un paziente con malattia di Marchiafava-Bignami (MBD) associata a lesioni frontali corticali, senza sintomi specifici al primo accesso in Pronto Soccorso, e insorgenza tardiva di sintomi psichiatrici atipici. Metodi. Descriviamo il caso di un paziente di 44 anni con storia di abuso cronico di alcol, a cui è stata diagnosticata la MBD. Risultati. La risonanza magnetica ha evidenziato lesioni nello splenio e corpo del corpo calloso e lesioni bilaterali della corteccia frontale. Il paziente ha sviluppato sintomi psichiatrici atipici a insorgenza tardiva, che sono risultati essere resistenti alle terapie farmacologiche impostate. Discussione. Il caso che descriviamo sembra supportare le attuali, ma ancora scarse evidenze che descrivono il coinvolgimento corticale nella MBD, suggerendone l'associazione con una prognosi peggiore. I sintomi psichiatrici possono risultare difficili da trattare a causa della resistenza alle terapie. Conclusione. Il coinvolgimento di psichiatri, radiologi e neurologi secondo un approccio di consultazione-liaison si è dimostrato di fondamentale importanza per la diagnosi e l'impostazione della terapia adeguata al paziente.

  6. CHILES Con Pol: Probing galaxy evolution, the dark Universe, and cosmic magnetism with a deep 1000 hour Jansky VLA survey

    2014-04-01

    We recently started a 1000 hour campaign to observe 0.2 square degrees of the COSMOS field in full polarization continuum at 1.4 GHz with the Jansky VLA, as part of a joint program with the spectral line COSMOS HI Large Extragalactic Survey (CHILES). When complete, we expect our CHILES Continuum Polarization (CHILES Con Pol) survey to reach an unprecedented SKA-era sensitivity of 0.7 uJy per 4 arcsecond FWHM beam. Here we present the key goals of CHILES Con Pol, which are to (i) produce a source catalog of legacy value to the astronomical community, (ii) measure differential source counts in total intensity, linear polarization, and circular polarization in order to constrain the redshift and luminosity distributions of source populations, (iii) perform a novel weak lensing study using radio polarization as an indicator of intrinsic alignment to better study dark energy and dark matter, and (iv) probe the unknown origin of cosmic magnetism by measuring the strength and structure of intergalactic magnetic fields in the filaments of large scale structure. The CHILES Con Pol source catalog will be a useful resource for upcoming wide-field surveys by acting as a training set for machine learning algorithms, which can then be used to identify and classify radio sources in regions lacking deep multiwavelength coverage.

    The structure stability and electronic properties of CumConCO (m+n=2-7) clusters have been systematically investigated using density functional theory (DFT) within the generalized gradient approximation (GGA). The results indicate that the ground state structures of CumConCO clusters obtained by adsorbing CO molecules on the top sites of stable CumCon clusters with C atoms and CO molecules have been activated during adsorption process. Cu2CO, CuCoCO, Cu3CoCO, Co4CO, Cu4CoCO and Cu3Co3CO clusters are stronger than other ground state clusters in thermodynamic stability. Cu2CO, Cu4CO and Cu6CO clusters show stronger chemical stability; Co2CO, Co4CO, Cu5CoCO, Cu3Co3CO, Cu2Co5CO and Co7CO clusters show better propensity to adsorb CO for these clusters have larger adsorption energies; Electronic states of Cu2Co3CO, CuCo4CO, Co5CO, Cu4Co3CO, Cu3Co4CO, CuCo6CO and Co7CO clusters are mainly influenced by those of 3d orbitals in Co and Cu atoms, the contribution to total magnetic moments of these clusters comes mainly from Co atoms and these clusters have high magnetism.

    Eukaryotic gene expression is regulated by transcription factors (TFs) binding to promoter as well as distal enhancers. TFs recognize short, but specific binding sites (TFBSs) that are located within the promoter and enhancer regions. Functionally relevant TFBSs are often highly conserved during evolution leaving a strong phylogenetic signal. While multiple sequence alignment (MSA) is a potent tool to detect the phylogenetic signal, the current MSA implementations are optimized to align the maximum number of identical nucleotides. This approach might result in the omission of conserved motifs that contain interchangeable nucleotides such as the ETS motif (IUPAC code: GGAW). Here, we introduce ConBind, a novel method to enhance alignment of short motifs, even if their mutual sequence similarity is only partial. ConBind improves the identification of conserved TFBSs by improving the alignment accuracy of TFBS families within orthologous DNA sequences. Functional validation of the Gfi1b + 13 enhancer reveals that ConBind identifies additional functionally important ETS binding sites that were missed by all other tested alignment tools. In addition to the analysis of known regulatory regions, our web tool is useful for the analysis of TFBSs on so far unknown DNA regions identified through ChIP-sequencing. PMID:26721389

    This study elucidated the experiences of eighteen Latina adults (mean age = 38.5 years) from "Promoviendo una Alimentación Saludable" Project who received nutritional intervention as part of the clinical trial. Half of the participants were first generation immigrants from Mexico (50%), followed by U.S. born with 16.7%. Remaining nationalities represented were Bolivia, Colombia, Guatemala, Honduras, Peru, and Venezuela with 33.3% combined. The average duration of living in the U.S. was 11.1 years. The mean body mass index (BMI) at baseline was 36.59 kg/m(2) (SD = 7.72). Based on the DSM-IV, 28% (n = 5) participants were diagnosed with binge-eating disorder, 33% (n = 6) with bulimia nervosa purging type and 39% (n = 7) with eating disorder not otherwise specified. Participants received up to three nutritional sessions; a bilingual dietitian conducted 97.8% of sessions in Spanish. In total, fifty nutritional sessions were included in the qualitative analysis. A three step qualitative analysis was conducted. First, a bilingual research team documented each topic discussed by patients and all interventions conducted by the dietitian. Second, all topics were classified into specific categories and the frequency was documented. Third, a consensus with the dietitian was performed to validate the categories identified by the research team. Six categories (describing eating patterns, emotional distress, Latino culture values, family conflicts associated with disturbed eating behaviors, lack of knowledge of healthy eating, and treatment progress) emerged from patients across all nutritional sessions. Considering the background of immigration and trauma (60%, n = 15) in this sample; the appropriate steps of nutritional intervention appear to be: 1) elucidating the connection between food and emotional distress, 2) providing psychoeducation of healthy eating patterns using the plate method, and 3) developing a meal plan.

    Objective. To study the pathogenic feature of liver injury, activation of hepatic stellate cells, and dynamic expression of TGF-β1/TGF-β3 to reveal their role in liver injury induced by ConA. Methods. Mice were randomly divided into control group and ConA treatment group. ConA (20 mg/kg) was injected through vena caudalis in ConA treatment group; the controls received the same volume of saline injection. After injection for 2 h, 8 h, 24 h, and 48 h, animals were terminated. Blood, liver, and spleen were harvested. Liver function and histopathology were studied. α-SMA, vimentin, TGF-β1, and TGF-β3 were detected. Results. After ConA injection, liver damage started to increase. Expression of α-SMA, vimentin, TGF-β1, and TGF-β3 was significantly enhanced; all above indicators reached peak at 8 h; but from 24 h after ConA injection, TGF-β3 expression began to decline, while the TGF-β1/TGF-β3 ratio at 48 h was significantly lower than control. Conclusion. (1) Autoimmune liver injury induced by ConA showed time-based features, in which the most serious liver lesions happened at 8 h after ConA injection. (2) Early activation of HSC and imbalance expression of TGF-β1 and TGF-β3 existed in ConA-induced acute autoimmune liver injury, which may be associated with liver dysfunction and the mechanisms of progression to fibrosis.

    Objetivos: Conocer las actividades profesionales que realizan habitualmente los prevencionistas y su grado de satisfacción con las mismas. Métodos: Se accedió a una muestra de 236 técnicos de prevención con actividad en servicios de prevención ajenos de las comunidades autónomas de Baleares, Andalucía y Madrid a los que se les administró un cuestionario entre noviembre de 2009 y mayo de 2011 basado en el cuestionario propuesto por la Asociación Internacional de la Seguridad Social y la Red Europea de Organizaciones Profesionales en Salud y Seguridad (ISSA-ENSHPO). Resultados: Las tareas más frecuentemente realizadas por los prevencionistas en nuestra muestra (80% o más las realizan como mínimo una vez al mes) son la evaluación de riesgos, la formulación de recomendaciones preventivas, la información y la formación. Algunas tareas, como la fijación de criterios de selección del personal o la realización de análisis coste-beneficio, son mayoritariamente (por más del 50% de los encuestados) consideradas como impropias de los profesionales de la prevención. Los encuestados desearían dedicar más tiempo a la mayoría de las tareas que llevan a cabo, especialmente a las relacionadas con la propia formación y con la interacción en el seno de la empresa. Conclusiones: En el patrón de actividad de los profesionales entrevistados predominan las tareas relacionadas con el asesoramiento técnico en el puesto de trabajo, la formación de trabajadores y la difusión de informaciones, siendo los ámbitos de la gestión del propio conocimiento y el de las relaciones humanas en la empresa los que generan un deseo de mayor dedicación.

    Estamos entrando en una era donde la ortogonalidad entre las investigaciones de carácter experimental y de naturaleza teórica se irá difuminando progresivamente y la problemática a resolver quedará en escena como el único actor principal de la obra. Como premisa para una cooperación teórico-experimental de igual a igual, la metodología químico-cuántica utilizada debe ser capaz de ofrecer resultados de carácter predictivo. Sin duda, esta madurez en la metodología químico-cuántica ya la hemos alcanzado hace algunos años, tal y como muestra entre otras muchas, la labor que nuestro grupo ha realizado en el transcurso de la última década, dentro del campo de la Espectroscopía Teórica. Los estudios realizados comprenden una amplia gama de sistemas, variando tanto en tamaño como en complejidad, abordando problemáticas espectroscópicas consideradas tradicionalmente como especialmente controvertidas. Nuestra contribución científica más relevante reside en el carácter cuantitativo de las asignaciones espectroscópicas que hemos propuesto en base a resultados ab initio. Recordemos que en los años noventa los resultados ab initio solían presentar para las energías de excitación de sistemas de tamaño molecular moderado, como el benceno, errores de más de 1 eV. En comparación con el éxito relativo de los métodos semiempíricos, la frustración de la metodología ab initio quedaba todavía más patente. Los estudios que hemos presentado representan una comprensión profunda de los espectros electrónicos en sistemas orgánicos claves, mostrando el camino a seguir para obtener asignaciones espectroscópicas precisas (entre 0.1-0.2 eV). La naturaleza del método CASPT2 junto al diseño de estrategias computacionales nos ha permitido alcanzar el carácter cuantitativo con el que se caracterizan nuestras contribuciones[1,2]. Por todo ello, algunos de los trabajos publicados se consideran clásicos dentro del campo, pues en cierto modo definen el

    Introducción: a los pacientes con riesgo cardiovascular se les recomiendan programas de pérdida de peso y dieta saludable, pero la eficacia de estos programas a la hora de reducir la mortalidad es controvertida. Objetivo: examinar los efectos agudos y a largo plazo de un programa de rehabilitación cardíaca de dos meses de duración sobre las quemocinas relacionadas con la inflamación en pacientes con enfermedad cardiovascular. Diseño: estudio de cohortes prospectivo. Métodos: se estudiaron 26 pacientes con enfermedad cardiovascular inscritos en un programa de rehabilitación cardíaca basado en intervenciones nutricionales y de ejercicio. Se analizaron el estilo de vida y variables clínicas, metabólicas e inflamatorias. Resultados: 88,5% eran hombres y la edad media fue de 54,9 ± 7,8 años. Al final del programa de rehabilitación cardíaca las variables del perfil glucémico y lipídico descendieron, excepto el colesterol de lipoproteínas de alta densidad, que aumentó. Ácido úrico, interleucina-6, interleucina-1 beta, adiponectina y leptina se mantuvieron estables. Interleucina-6 correlacionó positivamente con proteína C reactiva y negativamente con glucosa en sangre. Interleucina-1 beta correlacionó positivamente con proteína C-reactiva y negativamente con las cifras de presión arterial. Encontramos correlaciones significativas entre los cambios en interleucina-6 e interleucina- 1 beta y los cambios en los equivalentes metabólicos y proteína C-reactiva, antes y después del programa de rehabilitación cardíaca. No se observaron correlaciones significativas con peso, circunferencia de cintura o masa grasa. Conclusiones: la rehabilitación cardiaca mejora las variables antropométricas, las cifras de presión arterial, así como el perfil de lípidos y los resultados de la ergometría. Sin embargo, no se observaron cambios con respecto al estado inflamatorio.

    Community resources (parks, recreational facilities) provide opportunities for health promotion, but little is known about how to promote utilization of these resources and their impact on cardiovascular disease risk (CVD). This cohort study evaluated the impact of an intervention called Mi Corazon Mi Comunidad (MiCMiC), which consisted of promoting use of community physical activity and nutrition resources by Promotoras de Salud/Community Health Workers. Participants were assessed at baseline and following the 4-month intervention. Attendance records were objectively collected to assess utilization of intervention programing. A total of five consecutive cohorts were recruited between 2009 and 2013. Participants were mostly females (86.0%), on average 46.6 years old, and 81% were low in acculturation. Participants who completed follow-up (n = 413) showed significant improvements in reported health behaviors and body composition. Higher attendance significantly predicted greater improvements. The baseline to 4-month change for the highest vs. the lowest attendance quartiles were for weight (-5.2 vs. +0.01 lbs, p < 0.001), waist circumference (-1.20 vs. -0.56 inches, p = 0.047), hip circumference (-1.13 vs. -0.41 inches, p < 0.001); hours of exercise/week (+3.87 vs. +0.81 hours, p < 0.001), proportion of participants eating five servings of fruits and vegetables/day (+54.7 vs. 14.7%, p < 0.001). Following the Promotora-led MiCMiC intervention, substantial improvements in health behaviors and modest improvements in cardiovascular risk factors were found. Greater utilization of community resources was associated with more favorable changes. This study provided preliminary evidence for the effectiveness of Promotora-led interventions for promoting use of existing community resources in CVD risk reduction.

    Mexican Americans along the US-Mexico border have been found to be disproportionately affected by chronic diseases particularly related to lack of physical activity and healthful food choices. A community-wide campaign (CWC) is an evidence-based strategy to address these behaviors but with few examples of implementation in Mexican descent populations facing profound health disparities. We examined exposure to a CWC, titled Tu Salud ¡Sí Cuenta!, and its association with meeting the recommended minutes of moderate and vigorous physical activity weekly and consuming more portions of fruits and vegetables daily. A cross-sectional sample of 1438 Mexican descent participants was drawn from a city-wide, randomly-selected cohort interviewed between the years 2008 and 2012. Multivariable comparisons of participants exposed and not exposed to the CWC and meeting physical activity guidelines or their fruit and vegetable consumptions using mixed effects models were conducted. The community-wide campaign components included different forms of mass media and individually-focused components such as community health worker (CHW) home visits. After adjusting for gender, age, marital status, educational attainment, language preference, health insurance, and diabetes diagnosis, the strongest association was found between meeting physical activity guidelines and exposure to both CHW discussions and radio messages (adjusted OR=3.83; 95% CI= [1.28, 6.21]; p=0.0099). Participants who reported exposure to both radio and TV messages consumed more portions of fruits and vegetables than those who reported no exposure (adjusted RR=1.30; 95% CI= [1.02, 1.66]; p= 0.0338). This study provides insights into the implementation and behavioral outcomes associated with exposure to a community-wide campaign, a potential model for addressing lifestyle modifications in populations affected by health disparities.

    El trabajo que se presenta investiga la dinámica de las partículas de polvo interestelar eyectadas por estrellas gigantes rojas en un cúmulo globular utilizando simulaciones numéricas de su interacción con el campo gravitatorio y con la radiación electromagnética de las estrellas. Se pretende con ello determinar la distribución espacial de ese material como una función del tiempo en un sistema similar a NGC 104 (47 Tuc). A partir de la distribución espacial resultante se obtuvo el espectro infrarrojo integrado el cual sugiere que el máximo contraste con la radiación estelar ocurre en longitudes de onda cercanas a 300 μm y que decrece rápidamente hacia longitudes de onda menores, en las que suelen realizarse las observaciones.

    Lectins recognize and reversibly bind to carbohydrates attached to proteins and lipids modulating a variety of signaling pathways. We previously showed that ConBr, a lectin from Canavalia brasiliensis seeds, produced an antidepressant-like effect in mice by modulating the monoaminergic neurotransmitter systems. Moreover, ConBr blocked hippocampal neurotoxicity induced by quinolinic acid in vivo and by glutamate in vitro, suggesting a neuroprotective activity of ConBr via glutamatergic system modulation. Therefore, the present study was undertaken to investigate the involvement of the N-methyl-D-aspartate (NMDA) receptor and the L-arginine-nitric oxide (NO) pathway in the antidepressant-like action displayed by ConBr in the forced swimming test (FST). With the aim of verifying the involvement of NMDA receptors in the antidepressant-like effect of ConBr (10 μg/site, i.c.v.), an intracerebroventricular (i.c.v.) pretreatment with either NMDA (0.1 pmol/site) or D-serine (30 μg/site) was carried out. The results show that both treatments blocked the effect of ConBr. Furthermore, the coadministration of subeffective doses of the NMDA receptor antagonist MK-801 (0.001 mg/kg, i.p.) or ketamine (0.1 mg/kg, i.p.; NMDA receptor antagonist) and ConBr (0.1 μg/site, i.c.v.) caused a synergistic reduction in immobility time. In order to verify the dependence of the L-arginine-NO-cGMP pathway, on the effect of ConBr in the FST, a pretreatment with the NO precursor, L-arginine (750 mg/kg, i.p.), or the PDE5 inhibitor, sildenafil (5 mg/kg, i.p.), was performed. Both drugs abolished the antidepressant-like action of ConBr. Finally, the administration of subeffective doses of the soluble guanylate cyclase inhibitor 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ; 30 pmol/site, i.c.v.) and ConBr (0.1 μg/site, i.c.v.) produced a synergistic antidepressant-like effect in the FST. Taken together, the results suggest that the antidepressant-like effect of ConBr in the FST involves NMDA

Ademas, se presenta la sintesis y caracterizacion de nanoparticulas del polimero de coordinacion unidimensional [Fe(Htrz)2(trz)]BF4, obtenidas mediante el metodo de micelas inversas. Estas nanoparticulas, con una estrecha distribucion de tamanos centrada alrededor de los 11 nm, presentan una transicion de espin muy abrupta, con un ancho ciclo de histeresis termica de unos 40K. En el capitulo 3 se describe el proceso de modificacion del tamano de las nanoparticulas descritas en el capitulo anterior, llevado a cabo variando la proporcion de surfactante/H2O en el medio. Ademas, con el objetivo de modificar las propiedades magneticas de las nanoparticulas obtenidas en el capitulo 2, se lleva a cabo la sintesis de nanoparticulas de polimeros de la misma familia del [Fe(Htrz)2(trz)]BF4. En concreto se sintetizaron 3 nuevos tipos de nanoparticulas basadas en el polimero [Fe(Htrz)1-x(NH2trz)x](ClO4)2, siendo x = 0.05, 0.15 y 0.3, en cada caso. Estas nanoparticulas siguen presentando una estrecha distribucion de tamanos y una transicion de espin muy abrupta y con un ancho ciclo de histeresis. Ademas, se observa que este ciclo se desplaza a temperaturas mas proximas a la temperatura ambiente a medida que se aumenta el porcentaje de 4-amino-1, 2, 4- triazol en la muestra. Pero al mismo tiempo se produce una disminucion de la anchura de este ciclo. Por ultimo, en este capitulo se presenta la

    Objective The assessment of response to lithium maintenance treatment in bipolar disorder (BD) is complicated by variable length of treatment, unpredictable clinical course, and often inconsistent compliance. Prospective and retrospective methods of assessment of lithium response have been proposed in the literature. In this study we report the key phenotypic measures of the “Retrospective Criteria of Long-Term Treatment Response in Research Subjects with Bipolar Disorder” scale currently used in the Consortium on Lithium Genetics (ConLiGen) study. Materials and Methods Twenty-nine ConLiGen sites took part in a two-stage case-vignette rating procedure to examine inter-rater agreement [Kappa (κ)] and reliability [intra-class correlation coefficient (ICC)] of lithium response. Annotated first-round vignettes and rating guidelines were circulated to expert research clinicians for training purposes between the two stages. Further, we analyzed the distributional properties of the treatment response scores available for 1,308 patients using mixture modeling. Results Substantial and moderate agreement was shown across sites in the first and second sets of vignettes (κ = 0.66 and κ = 0.54, respectively), without significant improvement from training. However, definition of response using the A score as a quantitative trait and selecting cases with B criteria of 4 or less showed an improvement between the two stages (ICC1 = 0.71 and ICC2 = 0.75, respectively). Mixture modeling of score distribution indicated three subpopulations (full responders, partial responders, non responders). Conclusions We identified two definitions of lithium response, one dichotomous and the other continuous, with moderate to substantial inter-rater agreement and reliability. Accurate phenotypic measurement of lithium response is crucial for the ongoing ConLiGen pharmacogenomic study. PMID:23840348

    This study evaluated the influence of parameter values and variances and model architecture on modeled exposures, and identified important data gaps that influence lack-of-knowledge-related uncertainty, using Consexpo 4.1 as an illustrative case study. Understanding the influential determinants in exposure estimates enables more informed and appropriate use of this model and the resulting exposure estimates. In exploring the influence of parameter placement in an algorithm and of the values and variances chosen to characterize the parameters within ConsExpo, "sensitive" and "important" parameters were identified: product amount, weight fraction, exposure duration, exposure time, and ventilation rate were deemed "important," or "always sensitive." With this awareness, exposure assessors can strategically focus on acquiring the most robust estimates for these parameters. ConsExpo relies predominantly on three algorithms to assess the default scenarios: inhalation vapors evaporation equation using the Langmuir mass transfer, the dermal instant application with diffusion through the skin, and the oral ingestion by direct uptake algorithm. These algorithms, which do not necessarily render health conservative estimates, account for 87, 89 and 59% of the inhalation, dermal and oral default scenario assessments,respectively, according them greater influence relative to the less frequently used algorithms. Default data provided in ConsExpo may be useful to initiate assessments, but are insufficient for determining exposure acceptability or setting policy, as parameters defined by highly uncertain values produce biased estimates that may not be health conservative. Furthermore, this lack-of-knowledge uncertainty makes the magnitude of this bias uncertain. Significant data gaps persist for product amount, exposure time, and exposure duration. These "important" parameters exert influence in requiring broad values and variances to account for their uncertainty. Prioritizing

    The University of Texas-Houston Health Science Center (UT-Houston) has created programs and activities to address the state's pressing needs in minority education. Through InterCon, a network of universities and K-12 schools, UT-Houston works with its partners to identify competitive candidates in the current pool of minority graduates with bachelor's degrees and to help them--along with their non-minority counterparts--progress in their education. Another objective is to expand the pool of minorities underrepresented in medicine who complete high school and go to college. In 1994 UT-Houston and Prairie View A&M University created a collaborative venture to provide new educational opportunities at UT-Houston for Prairie View's predominantly African American students. A three-track summer internship program--a result of that collaboration--has since been expanded to partnerships with other minority and majority universities throughout Texas. In 1998, for example, 108 undergraduate students from these universities (and 40 other universities nationwide) participated in research, professional, and administrative summer internships at UT-Houston. The InterCon network also has partnerships with K-12 schools. UT-Houston works with inner-city, suburban, and rural school districts to develop education models that can be transferred throughout the state. The partnerships deal with helping to teach basic academic skills and computer literacy, improve science-related instruction, meet demands for health promotion materials and information for school-initiated health and wellness programs, and develop distance-learning paradigms. UT-Houston views InterCon as a program helping Texas institutions to engage and adapt to the socioeconomic factors, demographic changes, and technology explosion that currently challenge public education.

    Sophocarpine is the major pharmacologically active compound of the traditional Chinese herbal medicine Radix Sophorae Subprostratae which has been used in treating hepatitis for years in China. It has been demonstrated that Sophocarpine exerts an activity in immune modulation and significantly decreases the production of inflammatory cytokines. However, the protective effects of Sophocarpine in T cell-dependent immune hepatitis remained unknown. The aim of this study was to determine the protective effects and pharmacological mechanisms of Sophocarpine on Concanavalin A (ConA)-induced hepatitis, an experimental model of T cell-mediated liver injury. BALB/C mice were pretreated with Sophocarpine or Bicyclol for five consecutive days. Thirty minutes after the final administration, the mice were injected with 15 mg⋅kg-1 of ConA intravenously. The results indicated that pretreatment with Sophocarpine significantly ameliorated liver inflammation and injury as evidenced by both biochemical and histopathological observations. Moreover, in Sophocarpine-pretreated mice, liver messenger RNA expression levels of chemokines and adhesion molecules, such as macrophage inflammatory protein-1α, CXC chemokine ligand 10, and Intercellular adhesion molecule-1, were markedly reduced. Further studies revealed that Sophocarpine significantly downregulated the expression of T-bet via inhibition of signal transducers and activators of transcription1 (STAT1) activation and overexpression of suppressor of cytokine signaling1, inhibiting the activation of Th1 cells and the expression of Interferon-γ (IFN-γ). Altogether, these results suggest new opportunities to use Sophocarpine in the treatment of T cell-mediated liver disease. In summary, Sophocarpine could attenuate ConA-induced liver injury, and the protective effect of Sophocarpine was associated with its inhibition effect of pro-inflammatory cytokines, chemokines, and the IFN-γ/STAT1 signaling pathway.

Este es un artículo de revisión sistemática de estudios publicados relacionados con la modificación del estilo de vida, la nutrición y la ingesta de vitaminas para prevenir o retrasar la aparición o progresión de la DMRE. Resultados: el análisis de los resultados de investigación consultados pone de manifiesto que la DMRE es una de las causas de ceguera más frecuentes en sujetos mayores de 55 años. La DMRE se caracteriza por disminución de la visión, metamorfosias, macropsias, micropsias y escotoma central. Es una enfermedad que debe ser diagnosticada a tiempo, ya que puede conducir a la ceguera irreversible. Entre los componentes de la dieta que en numerosos estudios epidemiológicos han mostrado una asociación inversa con la DMRE y que se revisan en este trabajo se encuentran: vitaminas (E y C), minerales (ej. zinc, selenio, manganeso y cobre) y carotenoides. Conclusiones: existe una evidencia importante de que puede aplicarse un soporte nutricional a pacientes con DMRE. Esto requiere de la determinación de los beneficios nutricionales de estos nutrientes (vitaminas, minerales y carotenoides), o bien de alimentos nutracéuticos en pro de la salud de este grupo de enfermos.

    A novel signal-on electrochemiluminescence (ECL) biosensor for detecting concanavalin A (Con A) was fabricated with phenoxy dextran-graphite-like carbon nitride (DexP-g-C3N4) as signal probe. In this construction strategy, the nanocomposites of three-dimensional graphene and gold nanoparticles (3D-GR-AuNPs) were used as matrix for high loading of glucose oxidase (GOx), which served as recognition element for bounding Con A. Con A further interacted with DexP-g-C3N4 through a specific carbohydrate-Con A interaction to achieve a sandwiched scheme. With the increase of Con A incubated onto the electrode, the ECL signal resulted from DexP-g-C3N4 would enhance, thus achieving a signal-on ECL biosensor for Con A detection. Due to the integration of the virtues of 3D-GR-AuNPs and the excellent ECL performance of DexP-g-C3N4, the prepared biosensor exhibits a wide linear response range from 0.05 ng/mL to 100 ng/mL and a low detection limit of 17 pg/mL (S/N=3).

    Assessment of the acute eye irritation potential is part of the international regulatory requirements for testing of chemicals. In the past, several prospective and retrospective validation studies have taken place in the area of serious eye damage/eye irritation testing. Success in terms of complete replacement of the regulatory in vivo Draize rabbit eye test has not yet been achieved. A very important aspect to ensure development of successful alternative test methods and/or strategies for serious eye damage/eye irritation testing is the selection of appropriate reference chemicals. A set of 80 reference chemicals was selected for the CEFIC-LRI-AIMT6-VITO CON4EI (CONsortium for in vitro Eye Irritation testing strategy) project, in collaboration with Cosmetics Europe, from the Draize Reference Database published by Cosmetics Europe based on key criteria that were set in their paper (e.g. balanced by important driver of classification and physical state). The most important goals of the CON4EI project were to identify the performance of eight in vitro alternative tests in terms of driver of classification and to identify similarities/differences between the methods in order the build a successful testing strategy that can discriminate between all UN GHS categories. This paper provides background on selection of the test chemicals. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The current study adopted a recovery-oriented care approach by emphasizing patients' perspectives and experiences regarding changes to a newly built mental health facility. The inpatient entrance, or "portal," intended to balance the aims of recovery-oriented care with minimizing risk. A mixed-methods study of the portal's pros and cons was conducted, according to four themes: (a) autonomy versus inconvenience; (b) safety and security versus stigma; (c) unit door versus portal operating costs; and (d) privacy versus community integration. Focus groups engaging with patients (N = 39) indicated that the design effectively supported recovery-oriented care. Patients did not find the portal to be stigmatizing or triggering and valued the safety and privacy it created, and visitors also generally had a positive experience. Survey responses (N = 101) from portal users were also positive about the new design. The study findings suggest that the pros outweighed the cons of the new design.

    The increased transmission and geographic spread of dengue fever (DF) and its most severe presentations, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS), make it one of the most important mosquito-borne viral disease of humans. Four distinct serotypes of dengue viruses are transmitted to humans through the bites of the mosquitoes. Currently there is no vaccine or antiviral drug against DV infections. Cross-protection between dengue virus serotypes is limited and antibody dependent enhancement (ADE) contributes significantly to the severity of the disease. The major challenge is to induce a broad durable immune response against all four serotypes of dengue virus simultaneously while avoiding the possible exacerbation of risk of developing the severe forms of disease through incomplete or modified responses. In order to address this worldwide concern, we present a synthetic consensus (SynCon) human codon optimized DNA vaccine that elicits immunity against all four dengue serotypes. We cloned consensus DIII domain of E protein from all serotypes and expressed them as a single open reading frame in a mammalian expression vector, called pDV-U-DIII (dengue-vaccine universal). In mice, this dengue-universal construct elicits significant level of anti-DIII antibody that neutralizes all four dengue subtypes and prevents cell death induced by dengue infection. This is the first SynCon DNA vaccine that provides tetravalent immunity against all four serotypes of dengue virus.

    Estudios previos en Buenos Aires reportaron altas prevalencias de HIV entre HSH, con valores que oscilan entre 9 y 14% durante casi 10 años de continuo testeo. El objetivo principal de este estudio fue la evaluación de factores relacionados al comportamiento de alto riesgo para transmisión del HIV entre HSH entre los que se incluyen el conocimiento y factores emocionales, socioculturales y ambientales. Por otro lado se realizó la estimación de prevalencia e incidencia de HIV utilizando RDS (Respondent Driven Sampling), así como la presencia de otras infecciones de transmisión sexual. Por último se evaluaron los hábitos de testeo para HIV indagando que factores facilitan o impiden su realización. El estudio constó de dos fases, en primer lugar una fase cualitativa y posteriormente una fase cuantitativa con una duración total de 4 años y medio. Durante la fase cualitativa se realizaron 44 entrevistas individuales en profundidad, 8 grupos focales y 10 observaciones etnográficas (hoteles, baños públicos ("teteras"), cines pornográficos, fiestas privadas, dark rooms y discotecas). Durante la fase cuantitativa del estudio se realizó el reclutamiento de 500 participantes que provinieron de la Ciudad Autónoma de Buenos Aires, así como del Gran Buenos Aires. El reclutamiento se comenzó con 16 participantes llamados semillas. Se realizó el diagnóstico de infección por HIV, hepatitis B y C (HBV y HCV), Treponema pallidum, Virus Papiloma Humano (HPV) y Chlamidias. La colaboración establecida entre los grupos de trabajo enfocados en áreas diversas posibilitó el abordaje conjunto de nuevas estrategias de investigación antes no exploradas en nuestro país. Los resultados más relevantes de esta investigación serán progresivamente publicados en sucesivos números de Actualizaciones en SIDA.

    SubCons is a recently developed method that predicts the subcellular localisation of a protein. It combines predictions from four predictors using a Random Forest classifier. Here, we present the user-friendly web-interface implementation of SubCons. Starting from a protein sequence, the server rapidly predicts the subcellular localisations of an individual protein. Additionally, the server accepts the submission of sets of proteins either by uploading the files or programmatically by using command line WSDL API scripts. This makes SubCons ideal for proteome wide analyses allowing the user to scan a whole proteome in few days. From the web page, it is also possible to download pre-calculated predictions for several eukaryotic organisms. To evaluate the performance of SubCons we present a benchmark of LocTree3 and SubCons using two recent mass-spectrometry based datasets of mouse and drosophila proteins.

    The dietary flavonoid quercetin has hepatoprotective effects. We analyzed the effects of quercetin on concanavalin A (ConA)-induced hepatitis in mice and its underlying molecular mechanisms of action. Mice were administered quercetin (50 mg/kg body weight, i.p.) or vehicle 30 min before intravenous administration of ConA. Quercetin pretreatment significantly reduced the ConA-induced elevations in plasma aminotransferase concentrations and liver necrosis, as well as reducing serum concentrations of the pro-inflammatory cytokines tumor necrosis factor (TNF)-α, interferon-γ, and interleukin-4. Quercetin pretreatment also reduced expression of high-mobility group box 1 protein (HMGB1) and toll-like receptor (TLR)-2 and TLR-4 messenger RNA (mRNA) and protein in liver tissues. Quercetin pretreatment significantly inhibited degradation of inhibitory kappa B alpha and modulated ConA-induced nuclear translocation in the liver of nuclear factor kappa B (NF-κB) p65. These results demonstrate that quercetin protects against ConA-mediated hepatitis in mice by attenuating the HMGB1-TLRs-NF-κB signaling pathway.

    In four studies we tested a new methodological approach to the investigation of evaluation bias. The usage of piecewise growth curve modeling allowed for investigation into the impact of people’s attitudes on their persuasiveness ratings of pro- and con-arguments, measured over the whole range of the arguments’ polarity from an extreme con to an extreme pro position. Moreover, this method provided the opportunity to test specific hypotheses about the course of the evaluation bias within certain polarity ranges. We conducted two field studies with users of an existing online information portal (Studies 1a and 2a) as participants, and two Internet laboratory studies with mostly student participants (Studies 1b and 2b). In each of these studies we presented pro- and con-arguments, either for the topic of MOOCs (massive open online courses, Studies 1a and 1b) or for the topic of M-learning (mobile learning, Studies 2a and 2b). Our results indicate that using piecewise growth curve models is more appropriate than simpler approaches. An important finding of our studies was an asymmetry of the evaluation bias toward pro- or con-arguments: the evaluation bias appeared over the whole polarity range of pro-arguments and increased with more and more extreme polarity. This clear-cut result pattern appeared only on the pro-argument side. For the con-arguments, in contrast, the evaluation bias did not feature such a systematic picture. PMID:26840219

    Objective Astaxanthin, a potent antioxidant, exhibits a wide range of biological activities, including antioxidant, atherosclerosis and antitumor activities. However, its effect on concanavalin A (ConA)-induced autoimmune hepatitis remains unclear. The aim of this study was to investigate the protective effects of astaxanthin on ConA-induced hepatitis in mice, and to elucidate the mechanisms of regulation. Materials and Methods Autoimmune hepatitis was induced in in Balb/C mice using ConA (25 mg/kg), and astaxanthin was orally administered daily at two doses (20 mg/kg and 40 mg/kg) for 14 days before ConA injection. Levels of serum liver enzymes and the histopathology of inflammatory cytokines and other maker proteins were determined at three time points (2, 8 and 24 h). Primary hepatocytes were pretreated with astaxanthin (80 μM) in vitro 24 h before stimulation with TNF-α (10 ng/ml). The apoptosis rate and related protein expression were determined 24 h after the administration of TNF-α. Results Astaxanthin attenuated serum liver enzymes and pathological damage by reducing the release of inflammatory factors. It performed anti-apoptotic effects via the descending phosphorylation of Bcl-2 through the down-regulation of the JNK/p-JNK pathway. Conclusion This research firstly expounded that astaxanthin reduced immune liver injury in ConA-induced autoimmune hepatitis. The mode of action appears to be downregulation of JNK/p-JNK-mediated apoptosis and autophagy. PMID:25761053

    The role of hepatic NK cells in the pathogenesis of HCV-associated hepatic failure is incompletely understood. In this study, we investigated the effect of HCV on ConA-induced immunological hepatic injury and the influence of HCV on hepatic NK cell activation in the liver after ConA administration. An immunocompetent HCV mouse model that encodes the entire viral polyprotein in a liver-specific manner based on hydrodynamic injection and φC31o integrase was used to study the role of hepatic NK cells. Interestingly, the frequency of hepatic NK cells was reduced in HCV mice, whereas the levels of other intrahepatic lymphocytes remained unaltered. Next, we investigated whether the reduction in NK cells within HCV mouse livers might elicit an effect on immune-mediated liver injury. HCV mice were subjected to acute liver injury models upon ConA administration. We observed that HCV mice developed more severe ConA-induced immune-mediated hepatitis, which was dependent on the accumulated intrahepatic NK cells. Our results indicated that after the administration of ConA, NK cells not only mediated liver injury through the production of immunoregulatory cytokines (IFN-γ, TNF-α and perforin) with direct antiviral activity, but they also killed target cells directly through the TRAIL/DR5 and NKG2D/NKG2D ligand signaling pathway in HCV mice. Our findings suggest a critical role for NK cells in oversensitive liver injury during chronic HCV infection.

    Semiempirical quantum-chemical X-ray macromolecular refinement using the program DivCon integrated with PHENIX is described. Macromolecular crystallographic refinement relies on sometimes dubious stereochemical restraints and rudimentary energy functionals to ensure the correct geometry of the model of the macromolecule and any covalently bound ligand(s). The ligand stereochemical restraint file (CIF) requires a priori understanding of the ligand geometry within the active site, and creation of the CIF is often an error-prone process owing to the great variety of potential ligand chemistry and structure. Stereochemical restraints have been replaced with more robust functionals through the integration of the linear-scaling, semiempirical quantum-mechanics (SE-QM) program DivCon with the PHENIX X-ray refinement engine. The PHENIX/DivCon package has been thoroughly validated on a population of 50 protein–ligand Protein Data Bank (PDB) structures with a range of resolutions and chemistry. The PDB structures used for the validation were originally refined utilizing various refinement packages and were published within the past five years. PHENIX/DivCon does not utilize CIF(s), link restraints and other parameters for refinement and hence it does not make as many a priori assumptions about the model. Across the entire population, the method results in reasonable ligand geometries and low ligand strains, even when the original refinement exhibited difficulties, indicating that PHENIX/DivCon is applicable to both single-structure and high-throughput crystallography.

    Nucleic acid aptamers are single-stranded DNA or RNA oligonucleotide sequences that bind to a specific target molecule with high affinity and specificity through their ability to adopt 3-dimensional structure in solution. Aptamers have huge potential as targeted therapeutics, diagnostics, delivery agents and as biosensors. However, aptamers composed of natural nucleotide monomers are quickly degraded in vivo and show poor pharmacodynamic properties. To overcome this, chemically-modified nucleic acid aptamers are developed by incorporating modified nucleotides after or during the selection process by Systematic Evolution of Ligands by EXponential enrichment (SELEX). This review will discuss the development of chemically-modified aptamers and provide the pros and cons, and new insights on in vitro aptamer selection strategies by using chemically-modified nucleic acid libraries.

    The pros and cons of the systemic and topical application of antioxidant substances are a subject of intense discussion among experts, with resulting confusion for consumers and producers. The objective of the present article is to clarify the various uncertainties relating to the use of antioxidant substances in dermatology. Whereas inappropriate application of antioxidant substances (concerning their concentration and composition) might induce harmful effects, the consumer will definitively benefit from physiological concentrations and compositions of antioxidants. The most suitable method is the consumption of natural antioxidants in the form of fruit and vegetables, for example. In addition, the skin, which also accumulates antioxidant substances, may profit from a sufficient antioxidative level, as damage induced by sun radiation in addition to skin aging is reduced.

    In this paper, the effect of the flood hazard map distributed to the residents who experienced flood disasters recently and an effective method for improving consciousness of flood di saster prevention are discussed. The questionnaire surveys were conducted on the residents living in the middle basin of the Nishiki River, Iwakuni city, Yamaguchi Prefecture, before and after the distribution of the hazard map. It is found from this investigation that "knowledge", "att achment", and "crisis", are the main factors in the psychological process related to the flood prevention behavior. The effect of the distribution of the hazard map is judged from the probability of the flood prevention behavior. In addition, it is also found that "knowledge", "flood experiment of T0514", "crisis", "eff ectiveness", "load", and "easy reading of the hazard map", are keys to improve the cons ciousness of flood di saster prevention.

    Context. High CO depletion as well as depletion of N-bearing species is observed in dense pre-stellar cores. It is generally accepted that depleted species freeze out onto dust grains to form icy mantles and that these ices suffer energetic processing due to cosmic ion irradiation and ion-induced UV photons. Aims: The aim of this work is to study the chemical and structural effects induced by ion irradiation on different CO:N2 mixtures at low temperature (16 K) to simulate the effects of cosmic ion irradiation of icy mantles. Methods: Different CO:N2 mixtures and pure CO and pure N2 were irradiated with 200 keV H+ at 16 K. Infrared transmittance spectra of the samples were obtained in situ before and after irradiation. The samples were warmed up and spectra were taken at different temperatures. The residues left over on the substrate at room temperature were analysed ex situ by micro Raman spectroscopy. Results: Several new absorption features are present in the infrared spectra after irradiation, indicating that new species are formed. The most abundant are nitrogen oxides (such as NO, NO2 and N2O), carbon chain oxides (such as C2O, C3O and C3O2), carbon chains (such as C3 and C6), O3 and N3. A refractory residue is also formed after ion irradiation and is clearly detected by Raman spectroscopy. Conclusions: We suggest that carbon chains and nitrogen oxides observed in the gas phase towards star-forming regions are formed in the solid phase after cosmic ion irradiation of icy grain mantles and are released into the gas phase after desorption of grain mantles. We expect that the Atacama Large Millimeter/submillimeter Array (ALMA), thanks to its high sensitivity and resolution, will increase the number of nitrogen oxides and carbon chain oxides detected towards star-forming regions.

    Neuropeptide S (NPS) has anxiolytic effects and facilitates extinction of cued fear in rodents. Here, we investigated whether NPS reverses social fear and social avoidance induced by social fear conditioning (SFC) and acute social defeat (SD), respectively, in male CD1 mice. Our results revealed that intracerebroventricular NPS (icv; 10 and 50 nmol/2 μl) reversed fear of unknown con-specifics induced by SFC and dose-dependently reduced avoidance of known aggressive con-specifics induced by SD. While 50 nmol of NPS completely reversed social avoidance and reinstated social preference, 10 nmol of NPS reduced social avoidance, but did not completely reinstate social preference in socially-defeated mice. Further, a lower dose (1 nmol/2 μl) of NPS facilitated the within-session extinction of cued fear, while a higher dose (10 nmol/2 μl) reduced the expression of cued fear. We could also confirm the anxiolytic effects of NPS (1, 10 and 50 nmol/2 μl) on the elevated plus-maze (EPM), which were not accompanied by alterations in locomotor activity either on the EPM or in the home cage. Finally, we could show that icv infusion of the NPS receptor 1 antagonist D-Cys((t)Bu)(5)-NPS (10 nmol/2 μl) did not alter SFC-induced social fear, general anxiety and locomotor activity. Taken together, our study extends the potent anxiolytic profile of NPS to a social context by demonstrating the reduction of social fear and social avoidance, thus providing the framework for studies investigating the involvement of the NPS system in the regulation of different types of social behaviour.

  19. Responses of urban crows to con- and hetero-specific alarm calls in predator and non-predator zoo enclosures.

    Urban animals and birds in particular are able to cope with diverse novel threats in a city environment such as avoiding novel, unfamiliar predators. Predator avoidance often includes alarm signals that can be used also by hetero-specifics, which is mainly the case in mixed-species flocks. It can also occur when species do not form flocks but co-occur together. In this study we tested whether urban crows use alarm calls of conspecifics and hetero-specifics (jackdaws, Corvus monedula) differently in a predator and a non-predator context with partly novel and unfamiliar zoo animal species. Birds were tested at the Tiergarten Schönbrunn in the city of Vienna by playing back con- and hetero-specific alarm calls and control stimuli (great tit song and no stimuli) at predator (wolf, polar bear) and non-predator (eland antelope and cranes, peccaries) enclosures. We recorded responses of crows as the percentage of birds flying away after hearing the playback (out of those present before the playback) and as the number of vocalizations given by the present birds. A significantly higher percentage of crows flew away after hearing either con- or hetero-specific alarm calls, but it did not significantly differ between the predator and the non-predator context. Crows treated jackdaw calls just as crow calls, indicating that they make proper use of hetero-specific alarm calls. Responding similarly in both contexts may suggest that the crows were uncertain about the threat a particular zoo animal represents and were generally cautious. In the predator context, however, a high percentage of crows also flew away upon hearing the great tit control song which suggests that they may still evaluate those species which occasionally killed crows as more dangerous and respond to any conspicuous sound.

    Occupational exposure to sevoflurane should not exceed 2 ppm. During inhalation sedation with sevoflurane using the anaesthetic conserving device (AnaConDa(®)) in the post-anaesthesia care unit, waste gases can be reduced by gas extraction systems or scavenging devices such as CONTRAfluran™. However, the efficacy of these methods has not been clearly established. To determine the safest scenario for healthcare workers during inhalation sedation with sevoflurane in the post-surgical intensive care unit. An experimental study on occupational exposure was conducted in a post-cardiothoracic care unit during March-August 2009. The measurements were performed in four post-cardiac surgery sedated adults in post-surgical intensive care unit and four nurses at the bedside, and at four points: scenario A, inhalation sedation without gas extraction system or contrafluran as a reference scenario; scenario B, applying a gas extraction system to the ventilator; scenario C, using contrafluran; and scenario 0, performing intravenous isolation sedation. Sevoflurane concentrations were measured in the nurses' breathing area during patient care, and at 1.5 and 8 m from the ventilator using diffusive passive monitor badges. All badges corresponding to the nurses' breathing area were below 2 ppm. Levels of sevoflurane detected using prevention systems were lower than that in the control situation. Only one determination over 2 ppm was found, corresponding to the monitor placed nearest the gas outlet of the ventilator in scenario A. Trace concentrations of sevoflurane were found in scenario 0 during intravenous sedation. Administration of sevoflurane through the AnaConDa(®) system during inhalation sedation in post-surgical intensive care units is safe for healthcare workers, but gas extraction systems or scavenging systems, such as CONTRAfluran™ should be used to reduce occupational exposure as much as possible.

Both churches received the American Diabetes Association's booklets on diabetes education, "Four Steps to Control Your Diabetes for Life." The intervention group also received weekly reviews of the booklet's information from the church pastor, who was educated about diabetes by a Latino family nurse practitioner. Pre- and postintervention levels of diabetes knowledge were measured using the Diabetes Knowledge Questionnaire. Mean changes in the Diabetes Knowledge Questionnaire (DKQ-24) survey from pretest to posttest indicated a significant increase in knowledge in both groups. Only the grades for the participants from the pastor-led group, however, moved from failure in knowledge to high levels of passing. One hundred percent of intervention group participants reported having read the literature. This pilot study supports the feasibility of a local Latino pastor, as a culturally consistent diabetes educator, to increase Latino parishioner's knowledge of diabetes. © 2015 Society for Public Health Education.

    The treatment of contaminated soil presents a significant technical problem. Soil-washing and chemical-extraction methods have proven to be effective for specific applications, but a process with more comprehensive treatment properties that is both cost-effective and environmentally propitious is needed. Bradtec, Inc., has developed a process, the ACT*DE*CON{sup SM} process, that has been tested on soil contaminated with plutonium. The process effectively extracted Pu-238 after three washes, reducing the contamination levels from approximately 20 Bq/g to 1.6--1.9 Bq/g and yielding a decontamination factor ranging from 11 to 13. By using four or more ACT*DE*CON{sup SM} washes or a continuous-flow process with ACT*DE*CON{sup SM} solvents on a pilot-scale test, a target decontamination level of 0.93 Bq/g might be achievable.

    PK 11195 and DAA1106 bind with high-affinity to the translocator protein (TSPO, formerly known as the peripheral benzodiazepine receptor). TSPO expression in glial cells increases in response to cytokines and pathological stimuli. Accordingly, [11C]-PK 11195 and [11C]-DAA1106 are recognized molecular imaging (MI) agents capable of monitoring changes in TSPO expression occurring in vivo and in response to various neuropathologies. Here we tested the pharmacological characteristics and TSPO-monitoring potential of two novel MI agents: NIR-conPK and NIR-6T. NIR-conPK is an analogue of PK 11195 conjugated to the near-infrared (NIR) emitting fluorophore: IRDye 800CW. NIR-6T is a DAA1106 analogue also conjugated to IRDye 800CW. We found that NIR-6T competed for [3H]-PK 11195 binding in astrocytoma cell homogenates with nanomolar affinity, but did not exhibit specific binding in intact astrocytoma cells in culture, indicating that NIR-6T is unlikely to constitute a useful MI agent for monitoring TSPO expression in intact cells. Conversely, we found that NIR-conPK did not compete for [3H]-PK 11195 binding in astrocytoma cell homogenate, but exhibited specific binding in intact astrocytoma cells in culture with nanomolar affinity, suggesting that NIR-conPK binds to a protein distinct, but related to, TSPO. Accordingly, treating intact astrocytoma cells and microglia in culture with cytokines led to significant changes in the amount of NIR-conPK specific binding without corresponding change in TSPO expression. Remarkably, the cytokine-induced changes in the protein targeted by NIR-conPK in intact microglia were selective, since IFN-γ (but not TNFα and TGFβ) increased the amount of NIR-conPK specific binding in these cells. Together these results suggest that NIR-conPK binds to a protein that is related to TSPO, and expressed by astrocytomas and microglia. Our results also suggest that the expression of this protein is increased by specific cytokines, and thus allows for

    Objetivo: Revisar la literatura científica relacionada con la información que reciben los consumidores sobre los distintos tipos de grasas de los alimentos a través del etiquetado. Método: Revisión sistemática de la documentación obtenida en las bases de datos MEDLINE (via PubMed), EMBASE, CINAHL, FSTA, Web of Science, Cochrane Library, SCOPUS y LILACS; hasta septiembre 2013. Los términos utilizados, como descriptores y texto libre, fueron: «dietary fats», «dietary fats, unsaturated» y «food labeling». Se utilizó el límite «humanos». Resultados: Se recuperaron 549 referencias, de las que se seleccionaron 36 artículos tras aplicar los criterios de inclusión y exclusión. Los principales efectos relacionados con la información del etiquetado estuvieron relacionados con el precio y lugar de compra/consumo, las dimensiones sensoriales, los hábitos dietéticos, la interpretación de logotipos y la educación. Conclusiones: El etiquetado sobre el contenido de grasa en los alimentos es una buena ayuda a la hora de tomar decisiones de consumo. La educación nutricional y de los significados de las etiquetas es fundamental y se mostró efectiva aunque no se haya logrado el “consumidor informado”. Se deberían dirigir las acciones formativas hacia las creencias y actitudes anteriores de los consumidores para hacer coherente el mensaje de salud y alimentación. Las etiquetas deberían ser homogéneas y reales a la hora de expresar composición o exponer logotipos. Los mensajes incluidos en el empaquetado deben ser claros y no inducir a engaño.

    panels are analysed to compare and select the best configuration. The presented research provides a deep knowledge of how they work as well as information and results for an improvement in future designs of building integrated photovoltaic systems. Este estudio se centra en analizar la influencia negativa de la temperatura en la produccion electrica de paneles fotovoltaicos al estar emplazados sobre cubierta de acero, como sucede en naves industriales y sobre un invernadero. Se estudian diferentes configuraciones que permitan refrigerar los paneles, reduciendo su temperatura y mejorar su rendimiento. Para abordar este problema, se han construido dos instalaciones experimentales, fieles a plantas solares en funcionamiento. Una instalacion engloba dos paneles fotovoltaicos sobre estructura fija al suelo. Uno de los paneles esta integrado sobre una superficie paralela y metalica. Entre ambas superficies existe un espacio que posibilita circular aire, permitiendo refrigerar el panel por conveccion natural, o conveccion forzada impulsando el aire con un ventilador. El otro panel, libre por su cara posterior y se ha considerado de referencia. Se ha estudiado el comportamiento del panel integrado sobre cubierta para diferentes secciones de aire y velocidades inducidas, comparandolo con el panel de referencia. Se ha desarrollado un modelo experimental que nos permite determinar la temperatura del panel en funcion de las variables que influyen en su refrigeracion. Adicionalmente, se han analizado los datos de una planta solar en funcionamiento, con paneles de igual caracteristicas, obteniendo correlaciones entre la temperatura del panel y las variables electricas y comparandolos con las obtenidas en la instalacion experimental. La segunda instalacion experimental reproduce parte de una instalacion solar sobre un invernadero, formada por cuatro paneles fotovoltaicos colocados sobre el plastico del invernadero, existiendo un canal divergente entre ambas superficies.

  10. Inversor Resonante de Tres Elementos L-LC con Caracteristica Cortocircuitable para Aplicaciones de Calentamiento por Induccion

    NASA Astrophysics Data System (ADS)

    Espi Huerta, Jose Miguel

    Los generadores de calentamiento por induccion son puentes inversores con carga resonante, cuya mision es basicamente crear una corriente sinusoidal de gran amplitud sobre la "bobina de caldeo", que forma parte del tanque resonante. En el interior de esta bobina se introduce la pieza que se desea calentar. EI campo magnetico creado induce corrientes superficiales (corrientes de Foucault) sobre la pieza, que producen su calentamiento. Los tanques resonantes (tambien llamados osciladores) utilizados en la actualidad son el resonante serie y el resonante paralelo. Aunque ya desde hace algun tiempo se vienen construyendo generadores de alta potencia basados en estos dos osciladores, el exito nunca ha. sido completo en ninguno de los dos casos. Tal y como se explica en la introduccion de esta memoria, los puentes inversores utilizados deben operar sobre una carga inductiva (corriente retrasada) para evitar el fenomeno de la recuperacion inversa de sus diodos y la consiguiente ruptura de los transistores. De la restriccion topologica anterior se deduce que el generador paralelo debe conmutar a frecuencias inferiores a la resonancia, y el serie a frecuencias superiores. A esta restriccion topologica hay que unir otra que es exclusiva del calentamiento por induccion: La corriente por la bobina de caldeo debe ser sinusoidal. De no ser asi, resultaria imposible disponer toda la potencia de calentamiento sobre la pieza en el espesor requerido por la aplicacion. Como consecuencia, los inversores no pueden operar por debajo de la frecuencia de resonancia del oscilador, pues en ese caso se amplifican los armonicos de orden superior de la tension/corriente de entrada situados sobre la resonancia, con la consiguiente distorsion de la corriente de salida. La conjuncion de las dos restricciones anteriores obligan al inversor paralelo a funcionar a la frecuencia de resonancia del oscilador. Esto imposibilita un control por variacion de frecuencia, regulandose la potencia desde la

    We present and discuss a particular group of plants used by a diversity of healers in the initiation process and apprenticeship of traditional medicine, as practiced by Amazonian societies in East-Central Peru. Often, these plants are locally called plantas con madre (plants with a mother), and are thought to guide initiates in the process of seeking sacred knowledge, learning about plant usage, and understanding traditional medicine practices. We illustrate the diversity of plants used in the apprenticeship and practice of traditional medicine, and nurture the discussion to better understand the terminology used by Indigenous healers to describe plant uses and their practices. The study was conducted between 2003 and 2008 with the participation of 29 curanderos (healers; 23 men, 6 women), 3 apprentices and 4 herbalists. The participants belonged to four ethnic groups: 17 Mestizos, 15 Shipibo-Konibo, 1 Ashaninka, and 1 Matsiguenga; a Spanish apprentice and an Italian herbalist were also included in the study. The field data were collected using semi-structured interviews, participant observation, and the witnessing of numerous healing sessions. Oral informed consent was obtained from each participant. We identified 55 plant species belonging to 26 botanical families, which are used in initiation processes and apprenticeships of traditional medicine. This group of plants is administered under strict conditions during training and healing sessions called dietas (shamanic diets), with the supervision of one or more maestros curanderos (master healers). We observed that during the shamanic diets, maestros curanderos administered plants depending on the teachings or tools he/she was passing on, and were based on a particular sequence during the initiation process: (I) purification and cleansing species; (II) sensitivity and intuition; (III) strengthening; and (IV) protection and defence. Traditional healers continue to be a primary source of health care for the majority

    Macromolecular crystallographic refinement relies on sometimes dubious stereochemical restraints and rudimentary energy functionals to ensure the correct geometry of the model of the macromolecule and any covalently bound ligand(s). The ligand stereochemical restraint file (CIF) requires a priori understanding of the ligand geometry within the active site, and creation of the CIF is often an error-prone process owing to the great variety of potential ligand chemistry and structure. Stereochemical restraints have been replaced with more robust functionals through the integration of the linear-scaling, semiempirical quantum-mechanics (SE-QM) program DivCon with the PHENIX X-ray refinement engine. The PHENIX/DivCon package has been thoroughly validated on a population of 50 protein–ligand Protein Data Bank (PDB) structures with a range of resolutions and chemistry. The PDB structures used for the validation were originally refined utilizing various refinement packages and were published within the past five years. PHENIX/DivCon does not utilize CIF(s), link restraints and other parameters for refinement and hence it does not make as many a priori assumptions about the model. Across the entire population, the method results in reasonable ligand geometries and low ligand strains, even when the original refinement exhibited difficulties, indicating that PHENIX/DivCon is applicable to both single-structure and high-throughput crystallography.

    4-Chloro 4-nitrostilbene (CONS) a new organic nonlinear optical material has been synthesized. Employing slow evaporation method, good optical quality single crystals (dimensions up to 6×2×3 mm(3)) have been grown using ethyl methyl ketone (EMK) as a solvent. The grown crystals have been subjected to various characterizations such as single crystal X-ray diffraction, powder XRD, Fourier Transform Infrared spectroscopy (FTIR), proton NMR, solid UV absorption, SHG studies. Single crystal X-ray diffraction reveals that the crystal system belongs to monoclinic with noncentrosymmetric space group P21. The UV-Vis absorption spectrum has been recorded and found that the cut off wavelength is 380 nm. Functional groups and the structure of the title compound have been confirmed by FTIR and (1)H NMR spectroscopic analyses respectively. Molecular mass of the CONS confirmed by the high resolution mass spectral analysis .The thermal behavior of the grown crystal has been studied by TG/DTA analysis and it shows the melting point is at 188.66 °C. Dislocations and growth pattern present in the grown crystal revealed by the etching study. The mechanical strength of the CONS crystal has been studied by Vicker's hardness measurement. The SHG efficiency of the grown crystal has been determined by Kurtz and Perry powder test which revealed that the CONS crystal (327 mV) has 15 times greater efficiency than that of KDP (21.7 mV).

    In the last decades, coagulase-negative staphylococci (CoNS), especially Staphylococcus epidermidis have become an important cause of bloodstream infections. In addition, rates of methicillin-resistance among CoNS have increased substantially, leading to the use of glicopeptides for therapy. The objective of this study was to evaluate eleven consecutives clinically relevant cases of oxacillin-resistant CoNS bacteremia in a general hospital localized in São Paulo city, Brazil. Five different species were identified by different phenotypic methods, including S. epidermidis (5), S. haemolyticus (3), S. hominis (1), S. warneri (1) and S. cohnii subsp urealyticus (1). A variety of Pulsed Field Gel Electrophoresis profiles was observed by macrorestriction DNA analysis in S. epidermidis isolates, but two of three S. haemolyticus isolates presented the same profile. These data indicated the heterogeneity of the CoNS isolates, suggesting that horizontal dissemination of these microorganisms in the investigated hospital was not frequent. One S. epidermidis and one S. haemolyticus isolates were resistant to teicoplanin and susceptible to vancomycin. The selective pressure due to the use of teicoplanin in this hospital is relevant.

    Coagulase negative staphylococci (CoNS) are nosocomial pathogens that cause indwelling medical device associated infections due to its biofilm forming potential and multiple antibiotic resistance. The current study focused on species identification, antibiotic resistance profile and molecular basis of biofilm formation and attachment of CoNS isolated from clinical samples. Along with this, molecular screening for mecA and newly identified surface colonization protein encoded by sasX gene was also conducted. S. epidermidis (n = 19, 47%) was identified as the most prevalent CoNS species and very interestingly two biofilm forming, mecA positive S. epidermidis isolates were found to carry all the biofilm associated genes screened in this study, which indicates its potential to form the strong biofilm. Another novel observation of the study is the detection of sasX gene in one biofilm positive S. epidermidis isolate. The study also identified one doxycycline resistant mecA positive, multidrug resistant S. haemolyticus isolate. In conclusion, the study signifies the existence of multiple biofilm related genes, multidrug resistance and the presence of sasX gene among clinical isolates of CoNS.

    In this study we explored the effects of microRNA let-7a on Con A-induced hepatitis and its possible mechanisms involved. We demonstrated that IL-6 and IL-17 expression were significantly upregulated in the liver following Con A treatment and IL-6 level was correlated with the IL-17 expression. To explore whether let-7a may have therapeutic effect on Con A-induced hepatitis, mice was infected with a lentiviral vector containing the let-7a sequence 7 days before Con A treatment. Significantly reduced Th17 cells and remarkably increased regulatory T cells frequency in the liver tissue were found as compared to control mice. It was accompanied by a significant decreased level of inflammatory cytokines as TNF-α, IL-6 and IFN-γ in the serum, and an decreased level of Th17 lineage-specific genes such as Il17a, Il17f, Il21 and Il23r. let-7a was further found to inhibit Th17 differentiation by downregulating IL-6 secretion. It may represent as a novel therapeutic strategy in treating immune-mediated inflammatory hepatitis.
