‘Boots for my Sancho’: structural vulnerability among Latin American day labourers in Berkeley, California

This paper addresses the structural vulnerability of Latin American undocumented day labourers in Northern California, as it is expressed in conversations on street corners where they wait for work. The intimate aspects of migrant experience become exemplified in jokes about the Sancho – a hypothetical character who has moved in on a day labourer's family and who enjoys the money he sends home. Joking turns to more serious topics of nostalgia and tensions with family far away, elements that come together with the fears and threats of labour on the corner and affect the way day labourers see themselves. Sexuality is rearticulated in the absence of women and masculinity becomes enmeshed in the contingencies of unregulated work and long-term separation from the people the men support. Together, these elements result in the articulation of threat to the immigrant body itself, which is exemplified by anxieties over homosexual propositions on the corner. Cet article aborde la vulnérabilité structurelle des travailleurs journaliers latino-américains sans papiers dans le Nord de la Californie, telle qu'ils l'expriment dans leurs conversations en attendant du travail aux coins des rues. Les aspects intimes de l'expérience de la migration sont exemplifiés à travers des blagues sur le Sancho – un personnage hypothétique qui, au pays natal, s'est installé dans la famille d'un journalier pour profiter de l'argent qu'elle reçoit de ce dernier. Les blagues deviennent alors des sujets de conversation plus sérieux, sur un fond de nostalgie et de tensions qui résulte de l'éloignement vis-à-vis de la famille – des éléments qui accompagnent les peurs et les menaces liées aux embauches des coins de rue et ont un impact sur la manière dont les journaliers se perçoivent. La sexualité est articulée par rapport à l'absence des femmes et la virilité s'empêtre dans les contingences du travail illégal et de la séparation sur le long terme d'avec les êtres que ces hommes soutiennent financièrement. Ensemble, tous ces éléments ont pour résultat une articulation de la menace vis-à-vis du corps de l'immigré lui-même, qui est exemplifiée par les angoisses dues aux propositions d'homosexuels aux coins des rues.

Exploratory Study on Occupational Health Exposure to Chemical Agents, in a Public Hospital in Valencia, Venezuela. Preliminar Assessment

Descriptive study that identified chemical agents (AQ) use and training on risk management and waste disposal techniques in a public Hospital in Valencia. A questionnaire was answered by 48 workers. Information obtained was: personal data, occupational history, AQ used; knowledge of risk management and waste disposal. There were 16 occupations from 12 “High Risk” areas. “Adult emergency” was the one with more workers (11 individuals), followed by “sterilization” and “clinical laboratory” (7 each) and oncology (5). The remained areas had less than 8.3% workers. The most used anesthetic agents were: Halothane, Enfluorane and Isofluorane 4.17% each and main antineoplastics used were: Doxorubicin 16.67% and Paclitaxel, 5-Fluoracil and Etoposide, 8.33% each. The most mentioned substances were: alcohol (70.8%) and Chlorine (64.6%). None of the answers regarding knowledge of AQ’ risk management and waste disposal was satisfactory. Statistical associations between training and several variables such as age, time in their job and being or not a professional, resulted non-significant. The correlation between training and the knowledge of AQ’s management was significant (p < 0.001). Participants showed that their knowledge about chemical occupational risk factors they are exposed to is still insufficient. Therefore, this theme should be included in graduate course curricula. These results provide important data and will serve as a pilot research for the follow up Phase II study that will include clinical aspects and environmental and biological monitoring.

A Grey Area of Rights and Knowledge: Displacement in Colombia, South-South Migration and Health Equity

Globalization and liberalization of the economies have produced among others drastic effects on the human mobility, generating confusion, enhancing discrimination and a lack of respect to the rights of several migrant collectives. In this article we analyse several challenges for the study of these phenomena, based on the case of the neglected health rights of Colombian women, who have been forced to displace by the country's internal conflict, and are thus pushed to cross the border to Ecuador. The article identifies several knowledge gaps that could allow and advance a better understanding of these critical subjects. The paper - a think piece -is based upon a general review of documents and studies on the relation between migration and health. The supporting theory on the research comes from international organisations such as the WHO and IOM, NGOs, grass-roots organisations and academic research. This paper shows the need for focusing on the reality of supra states which globalization has generated, and t e urgency of securing the access to essential health preconditions to migrant populations. These issues can no longer be neglected and should be included on agendas at international level, widening the approach of programs to the displaced/immigrant population by taking into account the need to ensure the essential health preconditions (equity), prevention, and protection. Further, it is clear that women and children require a better protection with enhanced prevention and responding measures to sexual abuse, stigmatisation, violence and the respect of their rights.

La experiencia de los receptores en el trasplante de órganos y tejidos

El trasplante de órganos y/o tejidos es considerado como una opción terapéutica viable para el tratamiento tanto de enfermedades crónicas o en estadios terminales, como de afectaciones no vitales, pero que generen una disminución en la calidad de vida percibida por el paciente. Este procedimiento, de carácter multidimensional, está compuesto por 3 actores principales: el donante, el órgano/tejido, y el receptor. Si bien un porcentaje significativo de investigaciones y planes de intervención han girado en torno a la dimensión biológica del trasplante, y a la promoción de la donación; el interés por la experiencia psicosocial y la calidad de vida de los receptores en este proceso ha aumentado durante la última década. En relación con esto, la presente monografía se plantea como objetivo general la exploración de la experiencia y los significados construidos por los pacientes trasplantados, a través de una revisión sistemática de la literatura sobre esta temática. Para ello, se plantearon unos objetivos específicos derivados del general, se seleccionaron términos o palabras claves por cada uno de estos, y se realizó una búsqueda en 5 bases de datos para revistas indexadas: Ebsco Host (Academic Search; y Psychology and Behavioral Sciences Collection); Proquest; Pubmed; y Science Direct. A partir de los resultados, se establece que si bien la vivencia de los receptores ha comenzado a ser investigada, aún es necesaria una mayor exploración sobre la experiencia de estos pacientes; exploración que carecería de objetivo si no se hiciera a través de las narrativas o testimonios de los mismos receptores

Estudio de la cultura, sus manifestaciones y efectos en una Red Inter-Organizacional

El presente trabajo tiene como propósito el estudio de la cultura, y el impacto que tiene esta en una red inter-organizacional. Para esto se realizó un estudio documental en el cual se hizo una revisión bibliográfica de los principales conceptos relacionados con la cultura y el enfoque de trabajo en red. Asimismo para dar cumplimiento al objetivo de la investigación, se realizó el análisis de varios estudios empíricos que muestran las relaciones entre cultura y redes y que a su vez reflejan las diferentes formas que existen de comprobar la efectividad de una red. Los resultados mostraron que variables de la cultura como la confianza, la comunicación y la similitud de las prácticas culturales influyen en el desempeño y la duración de la red inter-organizacional, de igual forma, se demostró que al momento de escoger un enfoque de trabajo en red, es importante tener en cuenta las diferencias entre las culturas organizacionales de los miembros de la red ya que es necesario hacer un ajuste cultural para garantizar el éxito de la misma.

Predictores de cambio en la función ventricular izquierda posterior a implante valvular aórtico transcateter comparado con reemplazo valvular aórtico quirúrgico en el hospital universitario fundación Cardioinfantil instituto de cardiología – Bogotá

Objetivos: Identificar predictores de recuperación de la función ventricular izquierda y comparar los hallazgos ecocardiográficos en pacientes con estenosis aórtica crítica sometidos a reemplazo quirúrgico de la válvula aórtica (RVA) o implantación de válvula aórtica transcatéter (TAVI). Métodos: Cuarenta y cuatro pacientes tratados con RVA se compararon con 34 pacientes con TAVI, los datos ecocardiográficos fueron retrospectivamente obtenidos antes de la intervención y previo al alta. Resultados: Se analizaron retrospectivamente pacientes tratados en la FCI - IC desde 2009 - 2015 (n = 78 pacientes, con una media de edad 70,29 ± 11,63, EuroSCORE logístico 3,75 (3-8,55) en RVA y 20,4 (15 , 47-23,32) en TAVI. Ambos grupos mostraron una disminución en los gradientes de la válvula aórtica, más en pacientes de TAVI, con un gradiente transaórtico pico (24,5 vs 18,5, p = 0,001) y medio (14 vs 10, p = 0,002) En comparación con RVA, TAVI presentó un mayor número de pacientes con insuficiencia aórtica paravalvular (47,1% frente a 2,3% p = 0.000). En total, el 61,5% presentó mejoría precoz de la función ventricular, el predictor en severo compromiso de la función del ventrículo izquierdo fue un alto índice de masa ventricular izquierda. Conclusiones: La implantación transcatéter de válvula aórtica es una alternativa al reemplazo quirúrgico de la válvula aórtica en pacientes con estenosis aórtica y alto riesgo quirúrgico. La recuperación postoperatoria precoz de la función ventricular izquierda en pacientes con severo compromiso de la función ventricular estuvo asociada a alto índice de masa ventricular izquierda.

Violence and growth in colombia : a review of the quantitative literature

This is a critical review of the empirical literature on the relationship between violence and economic growth in Colombia: an interesting case study for social scientists studying violence, conflict, crime and development. We argue that, despite the rapid development of this literature and the increasing use of new techniques, there is still much room for research. After assessing the contribution of the most influential papers on the subject, we suggest directions for future research.

Psycological violence against women in Colombia

Although violence against women has gain attention, there is little evidence of studies about phycological violence against a partner. This paper uses data from Encuesta Nacional de Demografíay Salud (ENDS) to assess empirically models of violence against a partner. One of the main findingsis that the higher the economic independence of the women, the lower the phycologicalviolence against a partner. Some other results show that women with higher education level, belongingto a violent or low income family and living in cities different from Bogotá is correlatedwith higher probability of phycological violence.

Apoyo social e ideación suicida en pacientes con cáncer

El diagnóstico de cáncer ha sido asociado con un alto riesgo de presentar ideación suicida en comparación con la población no oncológica, sin embargo se ha considerado al apoyo social como un factor protector para la ocurrencia de esta conducta. La presente investigación tuvo como objetivo identificar la relación entre el apoyo social percibido y la ideación suicida en 90 pacientes oncológicos adultos en Bogotá, bajo la hipótesis de que a mayor apoyo social percibido, menor presencia de ideación suicida. Se midió la variable de apoyo social a través del cuestionario Duke UNC y la ideación suicida a través de cuatro instrumentos: Escala de Ideación Suicida (SSI), Escala de Desesperanza de Beck (BHS), el ítem 9 del Inventario de Depresión de Beck (BDI-IA) y una entrevista semiestructurada. Los resultados mostraron que no existe relación entre el apoyo social percibido y la ideación suicida. Por otro lado se identificó una prevalencia de suicidio entre 5,6% y 22,77%, confirmando que el paciente con cáncer considera el suicidio y es fundamental evaluar esta variable en esta población. Se considera importante continuar con la realización de investigaciones que permitan generalizar los resultados a la población oncológica colombiana.

Case-Crossover Analysis of Air Pollution Health Effects: A Systematic Review of Methodology and Application

Case-crossover is one of the most used designs for analyzing the health-related effects of air pollution. Nevertheless, no one has reviewed its application and methodology in this context. Objective: We conducted a systematic review of case-crossover (CCO) designs used to study the relationship between air pollution and morbidity and mortality, from the standpoint of methodology and application.Data sources and extraction: A search was made of the MEDLINE and EMBASE databases.Reports were classified as methodologic or applied. From the latter, the following information was extracted: author, study location, year, type of population (general or patients), dependent variable(s), independent variable(s), type of CCO design, and whether effect modification was analyzed for variables at the individual level. Data synthesis: The review covered 105 reports that fulfilled the inclusion criteria. Of these, 24 addressed methodological aspects, and the remainder involved the design’s application. In the methodological reports, the designs that yielded the best results in simulation were symmetric bidirectional CCO and time-stratified CCO. Furthermore, we observed an increase across time in the use of certain CCO designs, mainly symmetric bidirectional and time-stratified CCO. The dependent variables most frequently analyzed were those relating to hospital morbidity; the pollutants most often studied were those linked to particulate matter. Among the CCO-application reports, 13.6% studied effect modification for variables at the individual level.Conclusions: The use of CCO designs has undergone considerable growth; the most widely used designs were those that yielded better results in simulation studies: symmetric bidirectional and time-stratified CCO. However, the advantages of CCO as a method of analysis of variables at the individual level are put to little use

Histological and functional aspects of Alpha-synuclein in neurodegeneration

Alpha-synuclein has been implicated in the cellular mechanisms that control auditory sensitivity. In other systems it can also confer protection against cellular injury. Auditory brainstem response thresholds and immunohistochemistry were used to assess the ability of alpha-synuclein to protect against oxidative damage to the cochlea.

Genetic and temporal aspects of protection by kanamycin against cochlear noise injury

Experiments explored the minimal kanamycin dosing regimen that renders protection against noise induced hearing loss in young CBA/J mice. We also tested the age-dependence of protection in CBA/J as well as the dependence of protection on a particular genetic background in experiments using young C57BL/6J and CBA/CaJ mice.
