Resumen: Objetivo: Describir presencia de síndrome de apneas e hipopneas obstructivas del sueño (SAHOS) en niños con alteraciones craneofaciales (ACF), asociar características biodemográficas y variables poligráficas, y analizar la conducta terapéutica decidida luego del estudio de sueño y la evaluación de un equipo multidisciplinario. Pacientes y Método: Estudio retrospectivo. Poligrafías realizadas a pa cientes entre 1 mes y 19 años con ACF. Se estableció una conducta inicial y proyectada, categorizada en asistencia ventilatoria, traqueostomía, quirúrgico, odontológico y médico. Se realizó estadística descriptiva e inferencial, evaluando asociación entre variables demográficas, poligráficas y conductas terapéuticas. Resultados: Se incluyeron 34 pacientes, mediana de edad 4,0 años (RIQ 0,9-6,5). El 41,2% tenía Fisuras Labiopalatinas, 35,3% Craneosinostosis y 23,5% Micrognatia. El 70,6% de las poligrafías estaban alteradas, de estas, el 26,5% se diagnosticó como SAHOS leve, 5,9% moderado y 38,2% severo. Existió asociación entre saturación mínima y diagnóstico de SAHOS (p = 0,0036); y en la presencia de SAHOS con la conducta inicial aplicada (p = 0,0013). No hubo relación significativa entre los distintos tipos de ACF con la conducta terapéutica seguida inicialmente (p = 0,6565). Con ductas iniciales y proyectadas respectivamente: Asistencia ventilatoria (11,8% y 2,9%), traqueostomía (11,8% y 0%), quirúrgico (35,2% y 26,5%), odontológico (20,6% y 53%) y tratamiento médico (20,6% y 17,6%). Conclusiones: El 70% de los pacientes con ACF presentó SAHOS. La mayor severi dad se observó en Fisura Labiopalatina y Craneosinostosis. Las conductas terapéuticas se orientaron principalmente a tratamientos quirúrgicos iniciales y odontológicos proyectados; la decisión se aso ció al diagnóstico de SAHOS y no al tipo de ACF.

Abstract: Objective: To describe the presence of obstructive sleep apnea syndrome (OSAS) in children with craniofacial anomalies (CFA), associate biodemographic characteristics and polygraph variables, and analyze the therapeutic management decided after the sleep study and the evaluation by a multidisciplinary team. Patients and Method: Retrospective study. Polygraphs were performed on patients aged between 1 month and 19 years with CFA. An initial and projected management was established categorized into ventilatory support, tracheostomy, surgery, dental, and medical treatment. Descriptive and inferential statistics were performed, evaluating the association between demographic and polygraph variables and therapeutic management. Results: 34 patients were included with a median age of 4.0 years (IQR 0.9 - 6.5). Diagnosis was 41.2% cleft lip and palate, 35.3% craniosynostosis, and 23.5% micrognathia. Polygraphs were altered in 70.6% of the cases; of these, 26.5% were diagnosed as mild, 5.9% moderate, and 38.2% severe OSAS. There was an association between minimum saturation and diagnosis of OSAS (p = 0.0036), and in the presence of OSAS with the initial management applied (p=0.0013). There was no significant relationship between the different types of CFA with the initial therapeutic management (p = 0.6565). Initial and projected managements, respectively: Ventilatory support (11.8% and 2.9%), tracheostomy (11.8% and 0%), surgery (35.2% and 26.5%), dental (20.6% and 53%), and medical treatment (20.6% and 17.6 %). Conclusions: 70% of the patients with CFA presented OSAS. The greatest severity was found in Cleft Lip and Palatine and Craniosynostosis. Therapeutic management was mainly oriented towards initial surgical and planned dental treatments based on the diagnosis of OSAS and not on the type of CFA.

Abstract Introduction There are few reports on mental health among the lesbian, gay, bisexual, and transgender (LGBT) population in the context of COVID-19, especially in South America. Objective To describe the prevalence of symptoms associated with mental health disorders, as well as to analyze the risk of their occurrence, in different groups of the Chilean LGBT population in the context of COVID-19. Method A total of 1,181 LGBT people, ranged from 18 to 64 years participated in an online survey, using the Depression Anxiety Stress Scales-DASS-21. The central tendency measures were analyzed, then cut-off points were used to establish prevalence according to sex and sexual orientation. Finally, the probability of symptoms was analyzed using odds ratio. Results Lower levels of mental health were identified among the bisexual and other sexual orientations (pansexual, demisexual, asexual, etc.) population as compared with gays and lesbians, finding a greater presence of depressive symptoms (p = .000), anxious (p = .000) and related to stress (p<.001). Similarly, bisexual women are more likely to present symptoms associated with mental health disorders than men, as lesbians do, as compared with gays in the case of anxiety. Gays are at a higher risk of stress than lesbians. Discussion and conclusion Even though the pandemic affected the entire population, results give evidence of disparities among the various LGBT communities, showing the need to focus on preventive interventions and the implications of increased risk in bisexual population, particularly women, who are affected by various cross discriminations.

Resumen Introducción Existen pocos reportes sobre la salud mental en poblaciones de lesbianas, gays, bisexuales y transexuales (LGBT) en el contexto del COVID-19, especialmente en Sudamérica. Objetivo Describir la prevalencia de síntomas asociados a problemas de salud mental, así como analizar su riesgo de ocurrencia en diferentes grupos de población LGBT chilena en el contexto de la pandemia del COVID-19. Método Participaron en una encuesta en línea un total de 1,181 personas LGBT, con edades comprendidas entre los 18 y los 64 años, quienes completaron el cuestionario DASS-21 (del inglés Depression Anxiety Stress Scales). Primero se analizaron las medidas de tendencia central, luego se estableció la prevalencia según sexo y orientación sexual y finalmente se analizó la probabilidad de presentar síntomas mediante el odss ratio. Resultados Se identificaron menores niveles de salud mental en la población bisexual y otras orientaciones sexuales (pansexual, demisexual, asexual, etc.), en comparación con gays y lesbianas, debido a una mayor presencia de sintomatología depresiva (p = .000), ansiosa (p = .000) y vinculada al estrés (p<.001). Asimismo, las mujeres bisexuales fueron más propensas que los hombres a presentar síntomas asociados a trastornos de salud mental, al igual que las lesbianas, en comparación con los gays en el caso de la ansiedad. Los gays tienen un mayor riesgo de estrés que las lesbianas. Discusión y conclusión Aun cuando la pandemia afectó a toda la población, los resultados evidencian las disparidades entre las distintas comunidades LGBT, mostrando la necesidad de centrarse en las intervenciones preventivas y las implicaciones de un mayor riesgo en la población bisexual, especialmente en las mujeres, que se ven afectadas por diversas discriminaciones cruzadas.

ABSTRACT: In Chile, the abuse of the freedom of enterprise has been felt with gravity in standard contracts. In the framework of the doctrine of the abuse of fundamental rights, this work studies the scope of the illegitimate exercise of this freedom. In such a perspective, the unfair terms are configured because of the abusive exercise of the contracting / negotiating power of the business owner. These are premeditated unfair actions that materialize through various business strategies and that, when inserted into the general contracting conditions, affect a significant number of consumers in a systemic manner. Six leading cases are offered to illustrate this thesis, which are especially useful for the analysis of the problems that freedom of enterprise presents to the country, in view of the current constitutional process.

RESUMEN: En Chile, el abuso de la libertad de empresa se ha hecho sentir con especial gravedad en los contratos por adhesión. Este trabajo estudia los alcances del ejercicio ilegítimo de la libertad de empresa en la materia, partiendo de la doctrina del abuso de los derechos fundamentales. En tal perspectiva, las cláusulas abusivas se configuran como resultado del ejercicio abusivo de la facultad de contratación/negociación del empresario. Se trata de injustos premeditados que materializan diversas estrategias de negocios y que, al insertarse en las condiciones generales de contratación, afectan con carácter sistémico a un número importante de consumidores. Se ofrecen seis casos ejemplares discutidos judicialmente que ilustran esta tesis, los cuales son de especial utilidad para el análisis de los problemas que la libertad de empresa presenta al país, de cara al actual proceso constituyente.

ABSTRACT OBJECTIVE To expose visibility of the health concerns of sexual and gender minority groups in Chile, as well as to provide a platform to advocate for policies that support the health and well-being of sexual and gender minority people in the country. METHODS The health conditions and risk factors of participants identified as sexual and gender minority were compared to those identified as cisgender heterosexual using data from the 2016-2017 National Health Survey. RESULTS Despite reporting higher self-rated health than heterosexual men, gay men had a higher risk of lifetime diagnosis of sexually transmitted infections. Compared to heterosexual women, the prevalence of depression was higher among bisexual women, who were also less likely to have been tested for HIV. Moreover, transgender participants were more likely to report depression and worse self-rated health than cisgender heterosexual participants. CONCLUSION Small sample sizes of sexual and gender minority subgroups might have obscured some differences that would have been observable in larger samples. Despite this, we found statistically significant sexual and/or gender identity differences in several health areas, especially mental, sexual, and overall health.

ABSTRACT: Recognizing the school as a fundamental space for gender socialization, the article describes the representations that teachers have about gender, sexuality, sexism in education and recent changes in gender relations. 5 focus groups were held, 4 in Santiago and 1 in Valparaíso between 2018 and 2019, which were analyzed using the NVIVO 11 program. The conclusions indicate that teachers understand the aspects related to sexist education and the factors that reproduce it or question it. Tensions are observed between teachers and students regarding issues of sexism, as well as within the teaching staff, between newly graduated teachers and those who have been teaching for more years. It is recommended to reinforce the initial training of teachers in sexuality and gender and to train already qualified teachers to face the challenges that social changes impose on the educational system.

RESUMEN: Reconociendo la escuela como espacio fundamental de socialización de género, el artículo describe las representaciones que el profesorado tiene acerca del género, la sexualidad, el sexismo en la educación y los recientes cambios en las relaciones de género. Se realizaron 5 focus groups, 4 en Santiago y 1 en Valparaíso entre 2018 y 2019, los que fueron analizados con el programa NVIVO 11. Las conclusiones indican que los/as docentes comprenden los aspectos relacionados a una educación sexista y los factores que la reproducen o cuestionan. Se observan tensiones entre profesores/as y estudiantes referente a los temas de sexismo, así como también al interior del profesorado, entre profesores/as recién titulados y quienes llevan más años de ejercicio docente. Se recomienda reforzar la formación inicial de profesores/as en sexualidad y género y capacitar a los profesores/as ya titulados para enfrentar los desafíos que los cambios sociales le imponen al sistema educativo.

RESUMEN El cultivo de cacao tiene una alta importancia social en Colombia, pero requiere la implementación de técnicas de cultivo que mejoren su productividad, principalmente, en la producción de cacao orgánico. La poda y los fertilizantes orgánicos fueron evaluados, como los tratamientos para incrementar el rendimiento de cacao, en una plantación antigua en el departamento Cundinamarca. La aplicación de fertilizantes orgánicos y la poda tuvieron efectos positivos sobre la morfometría del fruto y el rendimiento del cacao. La aplicación de fertilizantes orgánicos con poda, en general, aumentó la longitud y el diámetro de frutos de cacao. Se encontró una correlación negativa (R=-0,618) entre el contenido relativo de clorofila en hojas al final del período de cosecha y el número de frutos por árbol. Se obtuvo una correlación positiva (R=0,748) entre el peso fresco de frutos y el peso seco de semillas. No se estableció correlación entre el contenido relativo de clorofila en hojas y el peso seco de semillas. La poda más fertilización orgánica aumentó el peso seco total de semillas por árbol, en casi un 15 %, lo que convierte la poda con aplicación de fertilizante orgánicos en una herramienta para aumentar el rendimiento de cacao orgánico en antiguas plantaciones, en el departamento Cundinamarca.

ABSTRACT Cacao has high social importance in Colombia but requires cultivation techniques that improve its productivity, especially in the production of organic cacao. Pruning and organic fertilizers were assessed as treatments to increase the bean yield in an old cacao crop in Cundinamarca. The positive effects of organic fertilizer application and pruning on the pod morphometry and bean yield were established. The application of organic fertilizers with pruning, in general, increased the length and circumference of cacao pods. A negative correlation (R=-0.618) was found among the relative chlorophyll contents in leaves at the end of the harvest period and with the number of pods per tree. A positive correlation (R=0.748) was obtained between the fresh weight of pods and the dry weight of beans. No correlation was established between the relative chlorophyll contents in leaves and the bean dry weight. Pruning plus organic fertilization increased the total dry weight of beans per tree at almost 15 %, which makes pruning with organic fertilizer application the best tool for increasing yield in organic cacao production in old plantations in Cundinamarca.

Abstract In a regional dimension, two key factors of agricultural activity in Guasave, Sinaloa, Mexico that directly influence sustainable rural development are analyzed: intensive agriculture and soil quality. This research was designed as a qualitative descriptive study of this productive branch, for this purpose, 164 interviews with producers were conducted and various documents with information on the sector were analyzed, such as technical reports and bulletins. It was found that intensive agriculture predominates in the study area, with traditional production practices and patterns, such as gravity irrigation systems and excessive use of agrochemicals, which presupposes agricultural management that goes against the sustainable context. Action-research is required for the implementation of resilience strategies with a sustainable approach, aligned with the adequate environmental governance of the activity and the needs of the sector, since problems such as the loss of soil fertility, an increase in salinity and erosion in some agricultural farms continue to be observed.

Resumen En una dimensión regional, se analizan dos factores claves de la actividad agrícola de Guasave, Sinaloa, México que influyen directamente en el desarrollo rural sustentable: la agricultura intensiva y la calidad de suelos. La presente investigación se diseñó como un estudio cualitativo de tipo descriptivo de este ramo productivo, para ello se aplicaron 164 entrevistas a productores y se analizaron diversos documentos con información del sector, tales como informes técnicos y boletines. Se encontró que la agricultura intensiva predomina en el área de estudio, con prácticas y patrones de producción de tipo tradicional, como son sistemas de riego de gravedad y uso desmedido de agroquímicos, lo cual presupone manejos agrarios que van en contra del contexto sustentable. Se requiere de investigación-acción para la implementación de estrategias de resiliencia con un enfoque sostenible, alineadas a la gobernanza ambiental adecuada de la actividad y a las necesidades del sector, toda vez que se siguen observando problemas como la pérdida de fertilidad de los suelos, un incremento en la salinidad y erosión en algunos predios agrícolas.

Abstract: The Emotional Intimacy Scale (EIE) is a self-report instrument that assesses emotional intimacy in close relationships. The aim of this research was to examine the psychometric properties of the EIE for its use in heterosexual, gay and lesbian people who are currently involved in a couple relationship. The sample consisted of 883 Chileans, (404 men and 479 women; 565 heterosexuals and 318 homosexual), between the ages of 18 and 72. Using a Confirmatory Factor Analysis, the one-dimensional structure of the scale was replicated, achieving a good fit to the data, while the multi-group analysis revealed that the EIE-E (Spanish version) is invariant according to sex and sexual orientation. The internal consistency indices using Cronbach's alpha and McDonald Omega were appropriate, and a positive association was observed between emotional intimacy and relationship satisfaction. Finally, results showed that lesbian women showed higher levels of intimacy relative to the other groups. It is concluded that the EIE-E is an appropriate instrument for the study of emotional intimacy in people who are in a couple relationship, be they heterosexual men or women, gays or lesbians.

Resumen: La Escala de Intimidad Emocional (EIE) es un instrumento de auto-informe que evalúa la intimidad emocional en relaciones cercanas. El objetivo de esta investigación fue examinar las propiedades psicométricas de la EIE para su uso en personas heterosexuales, gais y lesbianas involucradas en una relación de pareja. La muestra incluyó 883 personas chilenas (404 hombres y 479 mujeres; 565 heterosexuales y 318 homosexuales), entre 18 y 72 años. Mediante un Análisis Factorial Confirmatorio, se replicó la estructura unidimensional de la escala logrando un buen nivel de ajuste a los datos, mientras que el análisis multigrupo reveló que la EIE-E (versión en español) es invariante según sexo y orientación sexual. Los índices de consistencia interna mediante el alfa de Cronbach y McDonald Omega fueron apropiados y se observó una asociación positiva entre la intimidad emocional y la satisfacción con la relación de pareja. Finalmente, se identificó que las mujeres lesbianas evidencian mayores niveles de intimidad que el resto de los grupos. Se concluye que la EIE-E es un instrumento apropiado para el estudio de la intimidad emocional en personas que se encuentran en una relación de pareja, sean estas hombres o mujeres heterosexuales, gais o lesbianas.

The Chilean House of Representatives is discussing the bill on “Dignified death and palliative care”, which regulates the so-called medical assistance in dying or euthanasia. This paper will critically analyze the different aspects of the bill, particularly concerning four main dimensions, namely, the patient's condition at the time of requesting euthanasia; the doctor-patient relationship and respect for the autonomy of both parties; the idea of medicine involved in it; and the possible therapeutic alternatives to euthanasia. This critical analysis raises the need to discuss in more depth a project that has to do with such important decisions about our lives and that implies a radical change in the way of thinking and practicing medicine.

SUMMARY: The insectivorous bat Myotis chiloensis is endemic of South America. Even though potentially pathogenic bacterial species of Mycoplasma have been reported from this species, there are no further studies regarding the bacterial communities they harbor. This may provide important insights for the better understanding of its ecology, diet and implications in cross-species pathogens transmission. Here we report a first survey on bacterial communities of M. chiloensis based on metagenomic analysis of fecal samples. We found that taxonomic profile is dominated by Proteobacteria (23.7 to 57.7 %) and Firmicutes (11.8 to 61.6 %), which main families are represented by Burkholderiaceae- Enterobacteriaceae and Veillonellaceae-Bacillaceae, respectively. Phyla Bacteroidetes, Actinobacteria, Cyanobacteria, Planctomycetes and Acidobacteria were also present with abundance above 1 % of the total reads. Variations among individuals could be observed at genus level and no significant differences were found between sex groups regarding taxonomic profiles and diversity. Potentially pathogenic species were also detected in all the samples, including Staphylococcus aureus and Clostridium perfringens. Our results highlight the significance M. chiloensis as a reservoir of pathogenic bacteria and its microbiota as an interesting ecological model due to its wide distribution. Further metagenomic studies are necessary for a better understanding of M. chiloensis diet and its host-symbiont relationships.

RESUMEN: El murciélago insectívoro Myotis chiloensis es endémico de América del Sur. A pesar de que en esta especie se han reportado bacterias potencialmente patógenas tipo Mycoplasma, no existen estudios sobre sus comunidades bacterianas, lo cual podría proporcionar información importante para una mejor comprensión de su ecología, dieta e implicaciones en la transmisión de patógenos. En el presente trabajo se realiza una descripción de las comunidades bacterianas del murciélago M. chiloensis basada en análisis metagenómico de muestras fecales. El perfil taxonómico encontradofue dominado por Proteobacterias (23,7-57,7 %) y Firmicutes (11,8-61,6 %), cuyas principales familias fueron representadas por Burkholderiaceae-Enterobacteriaceae y Veillonellaceae-Bacillaceae, respectivamente. También se encontraron los filos Bacteroidetes, Actinobacteria, Cyanobacteria, Planctomycetes y Acidobacteria con una abundancia superior al 1 %. Se observaron variaciones entre los individuos a nivel de género, sin diferencias significativas de los perfiles taxonómicos y diversidad según sexo. Se detectaron especies potencialmente patógenas en todas las muestras, entre ellos Staphylococcus aureus y Clostridium perfringens. Nuestros resultados destacan la importancia de M. chiloensis como un reservorio de bacterias patógenas y el estudio de su microbiota como un modelo ecológico debido a su amplia distribución. Más estudios metagenómicos son necesarios para comprender la dieta de M. chiloensis y sus relaciones huésped-simbionte.

Abstract Prejudice and discrimination have important effects on the well-being and quality of life of trans people. Hence, investigating with said population implies, in addition to actions to obtain relevant and truthful information, having the necessary actions to attend to their needs and peculiarities. These are populations that are difficult to access (hard-to-reach), stigmatized, in which there is no defined sampling frame, that have physical and mental health indicators lower than those of any other group with which we have worked and that, therefore, it is necessary to take extreme the precautions not to reproduce types of relationships that may be harmful or offensive. The purpose of the present article was to systematize part of our field experience with transgender people, so that it can be useful for those who study with this population. These recommendations aim to provide some conceptual, methodological and ethical guidelines, useful throughout the research process. In particular, we made a series of recommendations that cover from the moment of taking conceptual decisions about the design of the study, through contact with the organizations, until the completion of the field work and subsequent stage of dissemination of results. In particular, a series of recommendations are made regarding: specifying the definition of the group with which one works, recording the variety of gender identifications as people present them, using to sampling methods for hard-to-reach populations or hidden populations, deliver a retribution for the participation (consider participants as experts to be compensated for their work), including activists as experts in every stage of the study (study design, field work, data analysis and dissemination of results), piloting the instruments in specific population, preferably opt for group applications modality and continue with a debriefing, have specific assistance for participants during the application (special needs derived from their age, educational level, reduced mobility, among others), use non-stigmatizing and inclusive language, call together with trans organizations (in order to establish greater trust in the population), attend to a mobility of the population (so as not to replicate the sample in different places), carry out a committed listening and contemplate referral protocols (if necessary given the type of situations described by the participants and their current degree of elaboration), consider different trajectories of transition, conduct inter-analysis sessions and disseminate appropriately within the transgender population. These propositions are discussed in terms of their effects on trans communities, their usefulness and ethical scope, their articulation with the general requirements of all research, and their implications for activism. On the other hand, these recommendations can serve as criteria for evaluating the ethical dimension of research projects with trans people. It may therefore be important to project reviewers, editors, and reviewers of manuscripts submitted for publication. The perspective that we assume in this work is aligned with those called "evidence-based activism", which implies articulating a variety of knowledge, scientifically accredited and of an "experiential" type, in order to explore situations in which the team members Research staff are part of networks that involve them personally in their study topics. It is precisely the relationship with groups that work for the rights of minorities, activists and members of these groups is essential, since they have knowledge acquired through their experience as part of discriminated groups and they can contribute to the mobilization of knowledge in the governance of health issues.

Resumen El presente trabajo expone y fundamenta recomendaciones basadas en la experiencia de investigación en personas transgénero, con la intención de que puedan ser útiles a quienes realicen estudios con dicha población. Estas recomendaciones incluyen orientaciones conceptuales, metodológicas y éticas, aplicables a lo largo del proceso de investigación. En particular, las orientaciones cubren los siguientes temas: definir con precisión el colectivo con el que se trabaja, registrar la variedad de identificaciones de género posibles al interior del mismo, utilizar métodos de muestreo aptos para poblaciones de difícil acceso, retribuir la participación, incluir líderes e investigadores transgéneros como expertos, pilotar los instrumentos en la población que será investigada, optar por modalidades de recolección grupal de datos, ofrecer asistencia individualizada durante la recolección, utilizar un lenguaje no estigmatizante e inclusivo, convocar la participación en conjunto con organizaciones transgénero, atender a la movilidad geográfica de la población, realizar una escucha comprometida y contemplar protocolos de derivación, considerar las diferentes trayectorias de transición, realizar sesiones de interanálisis y, finalmente, difundir apropiadamente los hallazgos al interior de la población transgénero. Se discuten estas proposiciones en términos de sus efectos en las comunidades trans, su utilidad y alcances éticos, su articulación con exigencias generales de toda investigación y sus implicaciones para el activismo.

Abstract This article analyses the way in which the Chilean educational system has reacted both to recent socio-educational debates and to the transformations that society is experiencing in terms of gender, sexuality and family. Studies show how changes have taken place in these areas in society, but not in the educational system, where alternative family forms are invisible and restrictive visions of gender, youth sexuality and sexual diversity predominate, probably due to the lack of training that teachers themselves identify in these subjects. The article suggests carrying out specific studies with teachers and complementing the conceptual and investigative framework applied to non-sexist education with a non-genderist approach, incorporating sexual dissidence, emerging family forms and other gender-related aspects, not hitherto considered in approaches to research.

Resumen El presente artículo analiza la forma en que el sistema educativo chileno ha reaccionado tanto a los debates socioeducativos recientes como a las transformaciones que la sociedad está experimentando en términos de género, sexualidad y familia. Los estudios realizados muestran la producción de cambios en estos ámbitos en la sociedad, no así en el sistema educacional, desde donde se invisibilizan las formas familiares alternativas, predominan visiones restrictivas del género, la sexualidad juvenil y la diversidad sexual, situaciones probablemente relacionadas con la falta de formación que los mismos profesores/as reconocen tener en estos temas. El artículo sugiere la necesidad de realizar estudios específicos con docentes que complementen el marco conceptual e investigativo con que se ha trabajado la educación no sexista con un enfoque no generista, que incorpore las disidencias sexuales, las formas familiares emergentes y otros aspectos relacionados con el género hasta ahora no considerados en las aproximaciones investigativas.

ABSTRACT Background: The knowledge on the management of water as a vital resource to develop agriculture allows having greater effectiveness in its use. Goals: The agricultural activity in the lower part of the Sinaloa River depends on the fresh water of the regional dams and the aquifer. Methods: The use of groundwater represents approximately 15% of the total water used. In the presence of prolonged periods of drought, new wells are drilled without the use of an appropriate guide for farmers on the location of aquifer areas with a greater hydraulic transmissivity with the purpose of exploiting them more rationally. The National Water Commission has registered more than 680 wells on both banks of the Sinaloa River. Results: The information of 205 of these pumping wells for agricultural or domestic use and the specific capacity information was analyzed. Then, 79 out of 205 wells have pumping tests. It is then determined that the objective of this research work was to find the relationship between the specific capacity (Qe) and hydraulic transmissivity (T) data of the study area using the Thiem formula, considering a fixed value of the radius of influence. This hypothetical consideration and the heterogeneities of the aquifer environment add to the T-Qe relationship an additional component, it is determined that it has a normal behavior. Using the Kalman filter it is possible to eliminate or reduce such a component, thus improving the determination of the T-Qe relation of an R-value of 0.95 (without filter) to 0.97 (with filter), for a linear and exponential relationship. Conclusions: The application of a T-Qe estimate allows characterizing the aquifer area, with this procedure a map was obtained on the distribution of T, which will serve as a guide for future exploitations of groundwater in the study area.

RESUMEN Antecedentes: El conocimiento sobre el manejo del agua como recurso indispensable para desarrollar la agricultura permite tener mayor efectividad en su uso. Objetivos: La actividad agrícola en la parte baja del río Sinaloa depende del agua dulce de las presas regionales y del acuífero. Métodos: El uso del agua subterránea, representa aproximadamente el 15% del agua total usada. Ante la aparición de periodos de sequía prolongados, se perforan nuevos pozos sin el uso de una guía apropiada que oriente a los agricultores sobre la ubicación de las zonas acuíferas que tienen una mayor transmisividad hidráulica con el propósito de explotarlos de manera más racional. Resultados: La Comisión Nacional del agua tiene registrados más de 680 pozos en ambas márgenes del Río Sinaloa. Se analizó la información de 205 de estos pozos de bombeo para uso agrícola o doméstico y la información de capacidad específica. De este número, 79 pozos tienen pruebas de bombeo. Se determina entonces que el objetivo de este trabajo de investigación fue encontrar la relación entre los datos de capacidad especifica (Qe) y transmisividad hidráulica (T) de la zona de estudio usando la fórmula de Thiem, considerando un valor fijo del radio de influencia. Conclusiones: Esta consideración hipotética y las heterogeneidades del medio acuífero suman a la relación T-Qe una componente adicional, se determina que tiene un comportamiento normal. Mediante el filtro de Kalman es posible eliminar o reducir tal componente, mejorando así la determinación de la relación T-Qe de un valor r de 0.95 (sin filtro) a 0.97 (con filtro), para una relación lineal y exponencial. La aplicación de una estimación T-Qe permite caracterizar la zona acuífera, con este procedimiento se obtuvo un mapa sobre la distribución de T, que servirá de guía para futuras explotaciones del agua subterránea en la zona de estudio.

Background: Transgender population is at a higher risk of suffering mental health problems than cisgender population (people whose sex and gender identity are in agreement) and other sexual minorities (gays, lesbians, and bisexuals), partly due to the greater stress that they suffer or for being victims of sexual prejudice. Aim: To describe positive and negative mental health indicators in a sample of transgender people living in Chile. Material and Methods: An intentional sample of 377 transgender individuals older than 18 years, living in the country's northern, center and southern zones were studied. Sociodemographic and well-being features, negative emotional symptoms, suicidal behavior, and substance consumption were assessed. Results: A precarious mental health was confirmed among participants. A high frequency of depression, ideation and suicide attempts, and high levels of depression, anxiety, and stress symptoms were identified. Also, a high frequency of substance abuse was found. These mental health indicators varied according to the sex assigned at birth and gender self-identification. Conclusions: Transgender people experience precariousness and vulnerability in their mental health.
