Narrative literature and cancer: improving the doctor-patient relationship

The role of classical literature on the subject of pain and suffering in cancer and other serious illnesses, not only from the point of view of patients but also of hospital personnel, family, friends and family doctors, has not been deeply exploited to favor the human and professional experience of young and not so young oncologists. This manuscript is the result of an effort made by postgraduate students and faculty members at the School of Oncology at Parma University to review the literature on this subject. The aim of our work is to convey the message that before teaching relationship techniques it is important to instill a culture focused on the doctor-patient relationship. Classical literature can make an important contribution to awareness in this area

Resiliencia y autoorganización del grupo mazahua de milpa intercalada con árboles frutales (MIAF)

En este artículo se analizan las narrativas de autoorganización de la población productora de milpa intercalada con árboles frutales (MIAF) en la región mazahua al noroeste del Estado de México. Se llevó a cabo un estudio cualitativo de tipo biográfico, mediante entrevistas a 13 productoras/es. Las y los productores MIAF fueron impulsados por actores externos desde 2018 y se les proporcionó semilla, material para la siembra y capacitaciones. Posteriormente, se autoorganizaron de tres formas: acción colectiva, interacción entre productoras/es y dependencia de recursos propios. Como limitantes están los costos en la producción de alimentos y las políticas públicas. Encontramos que las narrativas de autoorganización abonan a la discusión sobre la resiliencia socioecológica. Es importante que las y los productores MIAF potencien su acción colectiva para hacer frente a las adversidades, principalmente a la sequía. Tanto a nivel familiar como comunitario se pueden impulsar prácticas sostenibles destinadas a desarrollar la resiliencia

Mujeres y organización comunitaria. El caso de las palmeadoras de Tlaxiaco, Oaxaca, México

Las mujeres indígenas de México construyen dinámicas organizacionales que les permiten garantizar la sobrevivencia familiar. Este artículo identifica los beneficios individuales y colectivos de los procesos organizativos en los cuales se involucran las mujeres dedicadas a la elaboración de tortilla artesanal para autoconsumo y venta que integran la Unión de Palmeadoras de la Heroica Ciudad de Tlaxiaco, Oaxaca, México. La información se obtuvo de mayo de 2015 a enero de 2017, a través de una estrategia metodológica mixta que involucró entrevistas, talleres, observación participante, registros de ventas a lo largo de 20 días y un censo de toda la organización. Los beneficios individuales fueron dos: la garantía de tener sitios de venta; la posibilidad del trueque en el mercado. Los beneficios colectivos fueron tres: disponibilidad diaria de tortillas artesanales, dinamización de la economía local; permanencia del oficio de palmeadora. Se concluye que el gremio se creó debido a la discriminación que enfrentan estas mujeres. Sin embargo, aún falta mucho por hacer ya que sus espacios de venta son incómodos y sus condiciones de trabajo siguen siendo precarias. Abstract Native women in Mexico engage in organizing dynamics that allow them to provide for their families. This paper identifies the individual and collective benefits of organizational processes for the women who belong to the Unión de Palmeadoras de la Heroica Ciudad de Tlaxiaco, Oaxaca, Mexico. These women make handmade tortillas for household consumption and sale. Data were obtained between May 2015 and January 2017 through a combination of fieldwork techniques: interviews, workshops, participant observation, sale registers during a 20-day period, and a census of the whole organization. Two individual benefits were identified: guaranteed selling spots; barter opportunities while at the market. Three collective benefits were identified: daily availability of handmade tortillas; the mobilization of the local economy; the permanence of the palmeadora trade. The paper concludes that the organization was created due to the discrimination faced by these women. However, a lot remains to be done since their selling spots are inappropriate and their working conditions continue to be precarious

Contribution of KRAS mutations and c.2369C > T (p.T790M) EGFR to acquired resistance to EGFR-TKIs in EGFR mutant NSCLC: a study on circulating tumor DNA

INTRODUCTION: KRAS oncogene mutations (MUTKRAS) drive resistance to EGFR inhibition by providing alternative signaling as demonstrated in colo-rectal cancer. In non-small cell lung cancer (NSCLC), the efficacy of treatment with EGFR tyrosine kinase inhibitors (EGFR-TKIs) depends on activating EGFR mutations (MUTEGFR). However, inhibition of EGFR may select resistant cells displaying alternative signaling, i.e., KRAS, or restoration of EGFR activity due to additional MUTEGFR, i.e., the c.2369C > T (p.T790MEGFR). AIM: The aim of this study was to investigate the appearance of MUTKRAS during EGFR-TKI treatment and their contribution to drug resistance. METHODS: This study used cell-free circulating tumor DNA (cftDNA) to evaluate the appearance of codon 12 MUTKRAS and p.T790MEGFR mutations in 33 advanced NSCLC patients progressing after an EGFR-TKI. RESULTS: p.T790MEGFR was detected in 11 (33.3%) patients, MUTKRAS at codon 12 in 3 (9.1%) while both p.T790MEGFR and MUTKRAS codon 12 were found in 13 (39.4%) patients. Six patients (18.2%) were KRAS wild-type (WTKRAS) and negative for p.T790MEGFR. In 8 subjects paired tumor re-biopsy/plasma samples were available; the percent concordance of tissue/plasma was 62.5% for p.T790MEGFR and 37.5% for MUTKRAS. The analysis of time to progression (TTP) and overall survival (OS) in WTKRAS vs. MUTKRAS were not statistically different, even if there was a better survival with WTKRAS vs. MUTKRAS, i.e., TTP 14.4 vs. 11.4 months (p = 0.97) and OS 40.2 vs. 35.0 months (p = 0.56), respectively. CONCLUSIONS: MUTKRAS could be an additional mechanism of escape from EGFR-TKI inhibition and cftDNA is a feasible approach to monitor the molecular development of drug resistance

Hyperbaric exposure and oxidative Stress in occupational activities (HEOxS): the study protocol

Background: Hyperbaric exposure (HE) is proven to be a stressor to several mechanisms in living cells. Even if after homeostasis restoration, harmful effects are expected, in particular a presence of free radicals. These latter are the stimulus to negative phenomenon as inflammation or cancer. In Italy, with 7500 km of sea shores, a large quantity of workers is exposed to HE during occupational activities. A deep knowledge of HE and bodily effects is not well defined; hence a multidisciplinary assessment of risk is needed. To detect one or more indicators of HE a research group is organised, under the INAIL sponsorship. The research project focused on the oxidative stress (OxS) and this paper details on the possible protocol to estimate, with a large amount of techniques on several human liquids, the relationship between OxS and HE. Specific attention will be paid to identify confounding factors and their influence. Methods: Blood and urine will be sampled. Several lab techniques will be performed on samples, both targeted, to measure the level of well-known biomarkers, and untargeted. Regard the formers: products of oxidation of DNA and RNA in urine; inflammation and temperature cytokines and protein carbonyles in blood. Untargeted evaluation will be performed for a metabolomics analysis in urine. Confounding factors: temperature, body fat, fitness, allergies and dietary habits. These factors will be assessed, directly or indirectly, prior and after HE. The final scope of the project is to determine one or more indicators that relates to HE in hits twofold nature: depth and duration. Conclusion: The relationship between OxS and HE is not deeply investigated and literature proposes diverging results. The project aims to define the time dependence of biomarkers related to OxS, to rise knowledge in risk assessment in workers exposed to HE

Turismo y Género. Una mirada desde Iberoamérica

En las últimas cuatro décadas ha crecido el interés de la academia, gobiernos y organizaciones internacionales por estudiar cómo ha sido, en qué circunstancias y qué efectos ha traído la incorporación de las mujeres al turismo. De esta forma se inicia un debate internacional en el que se cuestionan, por un lado, los efectos negativos de esta actividad en la vida de las mujeres y, por el otro, se realzan beneficios económicos que mejoran su calidad de vida y la de sus familias. A pesar del interés y la importante participación de mujeres en el sector turístico, aún son insuficientes los estudios enfocados en explicar y evidenciar su situación laboral. En este contexto, surge la idea de publicar un libro que compilara trabajos recientes en torno a las condiciones de las trabajadoras en el sector turístico de Iberoamérica.Esta obra se compone de tres secciones, Aproximaciones teórico metodológicas, Mujer y turismo en zonas rurales y La mujer en empresas turísticas, cuyas investigaciones abordan distintos temas para evidenciar los problemas enfrentados por las mujeres, proponer diversas soluciones y comprender su escenario laboral. En la primera sección, hay dos capítulos que proponen marcos teóricos para analizar el empoderamiento de las mujeres en el turismo rural. Los resultados de investigaciones de la segunda sección visibilizan las desigualdades, reflexionan y proponen acciones para mejorar las condiciones de las trabajadoras turísticas. En la última, en los tres capítulos, concentrados en las actividades empresariales, se estudian las desventajas y obstáculos de la empleada en alguna compañía turística.Universidad Autónoma del Estado de México

Guidelines for the use and interpretation of assays for monitoring autophagy (3rd edition)

In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. For example, a key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process versus those that measure fl ux through the autophagy pathway (i.e., the complete process including the amount and rate of cargo sequestered and degraded). In particular, a block in macroautophagy that results in autophagosome accumulation must be differentiated from stimuli that increase autophagic activity, defi ned as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (inmost higher eukaryotes and some protists such as Dictyostelium ) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the fi eld understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. It is worth emphasizing here that lysosomal digestion is a stage of autophagy and evaluating its competence is a crucial part of the evaluation of autophagic flux, or complete autophagy. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. Along these lines, because of the potential for pleiotropic effects due to blocking autophagy through genetic manipulation it is imperative to delete or knock down more than one autophagy-related gene. In addition, some individual Atg proteins, or groups of proteins, are involved in other cellular pathways so not all Atg proteins can be used as a specific marker for an autophagic process. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field

Volteando la tortilla. Género y maíz en la alimentación actual de México.

Ante escenarios complejos, patriarcales y desoladores que dejan ver el neoliberalismo, la globalización agroalimentaria, el calentamiento global y las contaminaciones de granos nativos por la imposición de transgénicos, nos cuestionamos si existen algunas alternativas para preservar el maíz nativo como un recurso multiestratégico (alimentario, económico, cultural, ecológico y tecnológico) tomando en cuenta las condiciones actuales de desigualdades sociales de género, etnia, clases y edad que predominan en el campo mexicano. Para responder a algunos cuestionamientos, este libro presenta algunas alternativas a través de diversas experiencias femeninas y de relaciones de género en torno al maíz y la alimentación. Todas ellas muestran que es posible construir una masa crítica para salvaguardar el maíz nativo bajo esas condiciones desoladoras, pero siempre y cuando se “voltee la tortilla”, metáfora que da pie al inicio de otra realidad humanizada y en sincronía con la naturaleza.Proyecto realizado con financiamiento Conacy
