Introducción: El desarrollo positivo es un estadio de ajuste psicosocial que acentúa las potencialidades y los recursos entre jóvenes y sus contextos próximos. En Australia, se desarrolló el primer modelo de desarrollo positivo para adultos emergentes, el cual consta de cinco componentes (competencia social, satisfacción con la vida, confianza y tolerancia con los otros, confianza hacia autoridades e instituciones, acción y compromiso cívico), pero no ha sido investigado en Chile. Objetivo: Analizar la evidencia disponible en la literatura científica sobre los cinco componentes del modelo de desarrollo positivo en adultos emergentes universitarios de Chile. Materiales y métodos: Revisión narrativa de la literatura publicada entre 2013 y 2023, en bases de datos Web of Science, Scopus, SciELO, Redalyc y Dialnet. Resultados: Se obtuvieron 83 artículos, de los cuales 53 cumplieron los requisitos de inclusión; en su mayor parte fueron estudios cuantitativos (81,13%) y en español (75,47%). Se evidenció una disparidad en la cantidad de estudios por temática; se encuentra mayor investigación en satisfacción con la vida y acción y compromiso cívico. Conclusiones: Existen brechas en la literatura científica chilena en el estudio del desarrollo positivo; además de que se discuten particularidades idiosincrásicas y desafíos asociados a la etapa de adultez emergente.

Introduction: Positive development is a stage of psychosocial adjustment that accentuates the potentials and resources of young people and their close contexts. The first positive development model for emerging adulthood was developed in Australia, which includes five components: social; life satisfaction; trust and tolerance of others; trust in the authorities and institutions; and action and civic engagement. However, this model has not been investigated in Chile. Objective: To analyze the evidence available in the scientific literature on the five components of the positive development model in emerging adults universities. Materials and methods: A narrative review of the literature published between 2013 and 2023 in the Web of Science, Scopus, SciELO, Redalyc, and Dialnet databases was conducted. Results: 83 articles were selected, of which 53 met the inclusion criteria; most of them were qualitative studies (81.13%) and in Spanish (75.47%). There is an evident disparity in terms of the number of studies and topics, e.g., there is more research on life satisfaction and civic action and commitment. Conclusions: There are gaps in the Chilean scientific literature in the study of positive development. In addition, idiosyncratic particularities and challenges associated with the stages of emerging adulthood are discussed.

Simultaneous determination of 11 water-soluble synthetic colorants in foods consumed in Chile by high-performance liquid chromatography with diode Array detection.

In Chile, limited information is available on colorants in commonly consumed foods among vulnerable age groups. We developed and validated a rapid HPLC-DAD method to simultaneously evaluate 11 synthetic colorants in candies, beverages, ice cream, and cereals. The method exhibited excellent analytical performance for all 11 colorants with LOD (0.44 - 1.55 mgL-1), LOQ v(1.32 - 4.70 mgL-1), precision (4.0 and 7.3% RSD), and recovery (80 - 105%) in fortified matrices (10-50-100 mgL-1). The highest detection frequencies were as follows: cereals > candies > beverages > ice cream. Sunset Yellow was the most prevalent colorant in all food matrices, followed by Allura Red and Azorubine. Positive samples contained between 1 and 5 synthetic colorants. With the exception of cereals, the colorant concentrations in the remaining matrices exceeded the Codex Alimentarius regulations and the values reported in other studies worldwide, indicating the Chilean population is at risk.

Analysis of public records of lobbying practices of the ultra-processed sugary food and drink industries in Chile: a qualitative study.

Background: Given the role of commercial determinants on sugar consumption and health, this study aimed to describe lobbying practices of the ultra-processed sugary food and drinks industries in Chile between 2014 and 2022. Methods: Official meetings between ultra-processed sugary food and drinks industries and related commercial actors and Chilean government officials were obtained from the Chilean Lobby Registry. Relevant commercial names were initially identified based on their market share and expanded iteratively based on information from relevant meetings. Qualitative analysis followed a deductive-inductive approach using the Corporate Political Activity Model to identify and classify objectives, framing and action strategies. Findings: From 237 records identified, the Ministries of Health, Social Development, and Economy were the most frequently lobbied. Industry representatives sought to achieve their short- and long-term objectives by targeting a diverse range of authorities, including Ministers and Under-secretaries, using different strategies. Framing strategies focused on presenting sugary food and drinks industries as socially responsible and legitimate policy actors and criticised public health initiatives as 'bad solutions'. Action strategies aimed to influence policymaking and nurture corporate reputations. Interpretation: Extensive lobbying took place by the sugary food and drinks industries between 2014 and 2022, a period when major public health policies were being discussed in Chile. Lobbying strategies varied to meet industry objectives and targeted a diverse range of government institutions including high-ranking officials. Tighter regulations to stop inappropriate industry influence in public health policymaking are urgently required. Funding: Agencia Nacional de Investigación y Desarrollo (Chile)-PhD Scholarship.

Critical swimming speed at different temperatures for small-bodied freshwater native riverine fish species.

This study evaluated the effect of fish total length (LT) and three water temperatures (10, 15 and 20 °C) on the critical swimming speed (Ucrit) of the species Percilia irwini (2.9-6.3 cm LT), Cheirodon galusdae (3.4-5.5 cm LT), and Trichomycterus areolatus (4.0-6.3 cm LT). An Ucrit estimation model was constructed for each species as a function of temperature and size. The results showed mean Ucrit for P. irwini of 44.56, 53.83 and 63.2 cm s-1 at 10, 15 and 20 °C, respectively: 55.34, 61.74 and 70.05 cm s-1 for C. galusdae and 56.18, 63.01 and 71.09 cm s-1 for T. areolatus. Critical velocity depended on the interaction between species, body length and water. The swimming performance increased significantly with rising temperature in all three species. The velocity also increased with greater fish total length. After controlling for fish total length, velocity also increased with higher temperature in the three species. This research is relevant to small fish species that require conservation measures.

Performance of vertical and horizontal treatment wetlands planted with ornamental plants in Central Chile: comparative analysis of initial operation stage for effluent reuse in agriculture.

This study comparatively evaluated effluent reuse from two TWs-a horizontal subsurface flow (HF) and a vertical subsurface flow (VF)-used for rural wastewater treatment in Central Chile during the initial operation stage. The two TWs were planted with Zantedeschia aethiopica and were operated for 10 months at a pilot scale. The water quality of the influent and effluents was measured and compared with reuse regulations. The results showed similarities in the behavior of the effluents from the two TWs, presenting differences only in the chemical oxygen demand (COD) and different forms of nitrogen, suggesting the necessity of complementary treatment stages or modifications to the operation. The effluents from the HF better fulfilled the reuse standards for irrigation, as the VF faced problems associated with its size. However, a complementary disinfection system is necessary to improve pathogen removal in the effluents coming from the two TWs, especially to be reused as irrigation water for crops. Finally, this work showed the potential for applying subsurface TWs for wastewater treatment in rural areas and reusing their effluents as irrigation water, practice that can contribute to reducing the pressure on water resources in Chile, and that can be used as an example for other countries facing similar problems.

Socio-spatial trajectories and health disparities among older adults in Chile.

In this study, we examine residential trajectories since birth among older adults in the Santiago Metropolitan Area, Chile, and their association with health outcomes. We linked retrospective residential information for a sample of 802 individuals aged 65-75 in 2019 to context-based information from decennial censuses. Our analysis reveals substantive heterogeneity in individuals' residential trajectories, thus mirroring social and urban changes in Chile's largest city. We found significant associations between residential histories and health outcomes at the time of the interview. Consistent residence in advantaged areas was linked to better health, whereas relocating to the metropolitan area from elsewhere was generally linked to poorer health, except for those moving to emerging middle-class areas. These findings underscore the importance of longitudinal and life course approaches in understanding the complex relationship between place and health.

Mental Health First Aid Guidelines for Argentina and Chile: Report on the study to adapt the Australian guidelines / Guías de primeros auxilios en salud mental para Argentina y Chile: un reporte del estudio de adaptación de las guías australianas.

Background: Mental health problems represent a growing global concern. This has intensified since the coronavirus pandemic and is also partly due to greater awareness of the extent of mental health problems and the lack of attention they have received over time. In many high-income countries, increases in service provision have been accompanied by efforts to increase the mental health literacy of the general population. One example of this in Australia, is the mental health first aid training program which is informed by the mental health first aid guidelines created to promote mental health literacy among the general population, reduce stigma, and enable lay people to provide timely support, and facilitate access to health services for a person developing a mental health problem or in a mental health crisis. Methods: Between March 2020 and May 2023, a consortium of researchers from Australia, Argentina and Chile carried out the cultural adaptation of five guidelines (drinking problems, depression, suicide risk, trauma, and psychosis) using the Delphi consensus methodology. Health professionals with expertise in each of the topics and people with lived experience (their own or as informal caregivers) from Argentina and Chile were grouped into separate panels. Over two survey rounds, they evaluated the items from the Australian guidelines and gave their opinion on the importance of their inclusion in the local guidelines. Additionally, they suggested items not included in the Australian guidelines. Results: This report presents the details of the methodology used and the most significant results of each of the five adapted guidelines, particularly, those of relevance to the Argentinian and Chilean context. The general acceptance of the role of the first aider stands out as an important outcome. However, in comparison to Australia, the first aider's role was reduced and the health professional role was expanded. Self-help recommendations were typically not endorsed by local experts, suggesting skepticism toward these strategies. Other specific recommendations for each of the guidelines are described and analyzed in this report. Conclusions: A study of the implementation of training courses based on these guidelines is required to make the necessary adaptations and determine their local usefulness.

Introducción: Los problemas de salud mental en la comunidad representan una preocupación global creciente, intensificada desde la pandemia por coronavirus y gracias a una mayor conciencia respecto de su extensión y del bajo nivel de atención que recibieron a lo largo del tiempo. En Australia se crearon las primeras guías de primeros auxilios en salud mental para promover un mayor conocimiento de temas de salud mental en la población general, brindar apoyo oportuno, facilitar el acceso a los servicios de salud por esta problemática, y disminuir el estigma asociado al padecimiento mental. Método: Un consorcio de investigadores de Australia, Argentina y Chile, entre marzo de 2020 y mayo de 2023, realizó la adaptación cultural de cinco guías (consumo problemático de alcohol, depresión, riesgo de suicidio, trauma, y psicosis) siguiendo la metodología de consenso Delphi. Profesionales expertos en cada uno de los temas y personas con experiencia vivida  (propia o como cuidadores informales) conformaron sendos paneles con miembros de Argentina y de Chile. En dos rondas de consulta evaluaron los ítems provenientes de las guías de Australia y opinaron sobre su pertinencia para formar parte de las guías locales. Adicionalmente, sugirieron ítems que no estaban contemplados en las guías australianas. Resultados: El presente reporte presenta el detalle de la metodología empleada y los resultados más significativos de cada una de las cinco guías adaptadas y, particularmente, su aplicabilidad para Argentina y Chile. Sobresale la aceptación general del rol del asistente de primeros auxilios en salud mental, aunque también con limitaciones en el rol y funciones en favor del privilegio de profesionales de la salud. Las recomendaciones de auto-ayuda fueron mayoritariamente no aceptadas por los expertos locales, sugiriendo desconfianza respecto de estas estrategias. Otras recomendaciones específicas para cada una de las guías se describen y analizan en este reporte. Conclusiones: Se requiere un estudio de la implementación de la capacitación en base a estas guías para realizar ulteriores adaptaciones y determinar su utilidad local.

Improvements in habitability and housing satisfaction after dwelling regeneration in social housing complexes. The RUCAS study.

Housing is a pressing problem worldwide and a key determinant of health and wellbeing. The right to adequate housing, as a pillar of the right to an adequate standard of living, means more than a roof to live under. Adequate means the dwelling must fulfill material functions and psychosocial functions, thus contributing to dwellers health and wellbeing. Social housing policies aim to fulfill the right to housing, but frequently fail in fulfilling the right to it being adequate. This study capitalizes on the implementation of a national urban regeneration program in two social housing villas in central Chile (one in Santiago, in the central valley, the other in Viña del Mar, a coastal city) to run a natural experiment assessing the impact of dwelling renovation on several dimensions of perceived habitability and housing satisfaction among the -mostly female-household homemakers. We use 5 waves of survey data collected with a step-wedge design to estimate the association between a time-varying exposure status (the intervention) and 7 binary outcomes for habitability and 5 for housing dissatisfaction, including overall housing satisfaction. We use Poisson regression models with robust variance and a random intercept at the respondent level. At baseline, reports of poor habitability and dissatisfaction across all features were markedly high, the highest levels of dissatisfaction being with acoustic insulation and dwelling size in both villas, and with indoor temperature in Santiago. The intervention resulted in statistically significant and markedly large improvements in reported habitability and dissatisfaction relative to those housing components targeted by the intervention, as well as with overall dwelling satisfaction in both study cases. Implications are, first, that the policy response to quantitative housing deficits must not overlook housing quality; second, that housing renovation appears as a promising intervention for qualitative housing crises; third, that while improvements in habitability and satisfaction are specific to the interventions in place, overall housing satisfaction can improve in more limited, tailored, dwelling renovation interventions. Social housing renovation in Latin America appears as a promising intervention to improve quality of life among the urban poor dwellers and reduce inequalities in health related to housing conditions.

Doubling the known diversity of a remote island fauna: marine bivalves of the Juan Fernández and Desventuradas oceanic archipelagos (Southeastern Pacific Ocean).

Juan Fernández and Desventuradas are two oceanic archipelagos located in the southeastern Pacific Ocean far off the Chilean coast that received protected status as marine parks in 2016. Remoteness and access difficulty contributed to historically poor biodiversity sampling and limited associated research. This is particularly noticeable for bivalves, with most prior regional publications focused on single taxa or un-illustrated checklists. This study investigates marine bivalves collected between the intertidal and 415 m depth during (1) the 1997 IOC97 expedition aboard the M/V Carlos Porter, with special focus on scuba-collected micro-mollusks of both archipelagos, (2) two expeditions by the R/V Anton Bruun (Cruise 12/1965 and Cruise 17/1966), and (3) Cruise 21 of USNS Eltanin under the United States Antarctic Program, which sampled at Juan Fernández in 1965. Also, relevant historical material of the British H.M.S. Challenger Expedition (1873-1876), the Swedish Pacific Expedition (1916-1917), and by German zoologist Ludwig H. Plate (1893-1895) is critically revised. A total of 48 species are recognized and illustrated, including 19 new species (described herein) and six other potentially new species. The presence of two species mentioned in the literature for the region (Aulacomya atra and Saccella cuneata) could not be confirmed. The genera Verticipronus and Halonympha are reported for the first time from the Eastern Pacific, as are Anadara and Condylocardia from Chilean waters. Lectotypes are designated for Arca (Barbatia) platei and Mytilus algosus. These findings double the number of extant bivalve species known from the Juan Fernández and Desventuradas archipelagos, highlighting the lack of attention these islands groups have received in the past. A high percentage of species endemic to one or both archipelagos are recognized herein, accounting for almost 78% of the total. The newly recognized level of bivalve endemism supports the consideration of Juan Fernández and Desventuradas as two different biogeographic units (Provinces or Ecoregions) of the Eastern Pacific Ocean.

Are Rattus rattus fleas invasive? Evaluation of flea communities in invasive and native rodents in Chile.

Co-invasion, characterized by the simultaneous introduction of hosts and parasites with the latter establishing themselves in native hosts, is a phenomenon of ecological concern. Rattus rattus, a notorious invasive species, has driven the extinction and displacement of numerous avian and mammalian species and serves as a key vector for diseases affecting both humans and wildlife. Among the parasites hosted by R. rattus are fleas, which exhibit obligate parasitic behaviour, a generalist nature and high prevalence, increasing the likelihood of flea invasion. Simultaneously, invasive species can serve as hosts for native parasites, leading to potential amplification or dilution of parasite populations in the environment. In Chile, R. rattus has been present since the 17th century because of the arrival of the Spanish colonizers through the ports and has spread throughout urban, rural and wild Chilean territories. This study aims to evaluate whether co-invasion of native fleas of invasive rats occurs on native rodents in Chile and to determine whether black rats have acquired flea native to Chile during their invasion. For this, we captured 1132 rodents from 26 localities (20° S-53° S). Rattus rattus was found coexisting with 11 native rodent species and two species of introduced rodents. Among the native rodents, Abrothrix olivacea and Oligoryzomys longicaudatus exhibited more extensive sympatry with R. rattus. We identified 14 flea species associated with R. rattus, of which only three were native to rats: Xenopsylla cheopis, Leptopsylla segnis and Nosopsyllus fasciatus. These three species presented a higher parasite load in black rats compared to native fleas. Leptopsylla segnis and N. fasciatus were also found associated with native rodent species that cohabit with R. rattus. The remaining species associated with R. rattus were fleas of native rodents, although they were less abundant compared to those associated with native rodents, except for Neotyphloceras pardinasi and Sphinctopsylla ares. Although there has been evidence of flea transmission from rats to native species, the prevalence and abundance were relatively low. Therefore, it cannot be definitively concluded that these fleas have established themselves in native rodent populations, and hence, they cannot be classified as invasive fleas. This study underscores R. rattus' adaptability to diverse environmental and geographical conditions in Chile, including its capacity to acquire fleas from native rodents. This aspect has critical implications for public health, potentially facilitating the spread of pathogens across various habitats where these rats are found.

The 5Cs of positive youth development: their impact on symptoms of depression, anxiety, stress, and emotional distress in Chilean adolescents.

Effective approaches to addressing mental health challenges faced by adolescents require a deep understanding of the factors contributing to optimal development, well-being, and prosperity. From the perspective of Positive Youth Development (PYD), this study proposes to examine the relationship between the 5Cs of PYD (Competence, Confidence, Connection, Character, and Caring) and symptoms of depression, anxiety, stress, and emotional distress among Chilean adolescents. A quantitative, cross-sectional, non-experimental study was conducted with 425 adolescents (ages 12 to 19, M = 14.95, SD = 1.81) from three Chilean cities: Arica (23%), Alto Hospicio (32%), and Iquique (46%). Data analysis included the use of confirmatory factor analysis (CFA) and structural equation modeling (SEM). The results indicate that two of the 5Cs, Confidence and Connection, have a significant negative direct effect on the four evaluated criterion indicators. These findings contribute to the literature on positive youth development in Latin America and underscore the importance of fostering confidence and connection in interventions aimed at promoting the mental health of adolescents in Chile and in similar contexts.

Protective factors for the risk of suffering intimate partner violence in help-seeking women survivors from a social organization in Chile.

Objective: Intimate partner violence (IPV) is a major public health problem in Latin America. The present study investigates the protective factors that contribute to minimizing the risk of exposure to IPV analyzing different variables in a sample of Chilean women victims of IPV. Methods: We used data from the Cicatrices Foundation, a nonprofit Chilean organization providing psychological support to IPV victims. Relevant variables for IPV prevention were identified analyzing a database containing all the information reported by victims during a structured interview. A final sample of 444 women suffering IPV was used in the present study. Results: Logistic regression analysis was calculated in order to make predictions related to IPV protective factors, showing that having a support network (OR = 2.85), treatment compliance (OR = 2.05) and being younger (OR = 0.95) increased the probability of not living with the aggressor. Another logistic regression analysis was calculated in order to predict IPV victims´ health taking medication intake as an indicator. A significant association was observed between this variable and working outside (p = 0.002) and between mediation intake and age (p < 0.001), with an OR of 1.987 and 0.93, respectively. Working outside and being younger were identified as protective factors against consuming medication. Conclusion: To the best of our knowledge, this is one of the first studies conducted in Chile on the prevention of IPV in a sample of victims seeking for help. Our results will contribute to guide policy makers, researchers and other women in the prevention of potential risks for IPV.

Enriching cross-sectoral collaboration to foster inclusive cultures in schools: a Model to address the needs of diverse Chilean Students.

Inclusive education involves the interaction of diverse actors from different societal sectors, such as education, health, and policy. Inclusion laws and regulations in Chile are relatively new and have been taken as a regional model. However, the efforts to implement them have revealed some structural difficulties that must be discussed. This conceptual analysis article aims to provide insights to enrich cross-sectoral collaboration to foster inclusive cultures in Chilean schools. Considering the OECD Analytical Framework, which describes a systemic approach, we provide definitions for the critical components of the model and discuss the advances and challenges of current Chilean public policies in this field -including the Chile Crece Contigo and the School Integration Programs (SIP)-, the Chilean education system functioning, the social contexts, and students' needs and supports based on the available evidence. Building from inclusive education literature and previous experiences, we delve into the model to address the needs of students with disabilities, social and cultural disadvantages, students belonging to the indigenous population, and students with a low socioeconomic level to propose action guidelines with a particular focus on integrating inclusive practices at the school level.

Identification of QTLs involved in destemming and fruit quality for mechanical harvesting of New Mexico pod-type green chile.

Introduction: Domestic production of pepper (Capsicum spp.) is shrinking while demand within the US is growing. Lack of availability and cost of labor often present an obstacle for domestic producers both practically and economically. As a result, switching to harvesting peppers mechanically is anticipated as a key strategy to help domestic producers compete in the international market. Mechanical harvest efficiency can be improved through breeding. One important trait that mechanical harvest compatible material should have is an easy destemming trait: low force separation of the pedicel and calyx from the fruit. Methods: To detect the genetic sources underlying a novel easy destemming trait for the purpose of future breeding efforts in New Mexico pod-type green chile, we performed QTL analysis on three F2:F3 populations, coming from three New Mexico pod-type varieties: 'NuMex Odyssey,' 'NuMex Iliad,' and 'NuMex Joe E. Parker,' each crossed with a parent with an easy destemming trait: MUC14. Genotyping was done through genotyping by sequencing (GBS) and phenotyping was done for destemming and fruit trait measurements. Correlations between measurements were found through the R package hmisc and QTL analysis was done through R/qtl. Results: A strong relationship was seen between destemming and aspects of fruit morphology, particularly, destemming force and fruit width (Pearson's correlation coefficient r=0.75). Major QTLs for destemming and fruit size were discovered. Of these, the largest destemming force QTLs for all populations (PVE=34.5-69.9%) were on chromosome 10, and in two populations QTLs for destemming force were found on chromosome 3 (Percent Variance Explained (PVE)=10.7-18.8%). Fruit size-related QTLs in all populations colocalized in these same areas on chromosomes 3 and 10. Discussion: This suggests that fruit shape may be genetically linked to destemming, and breeders interested in selecting for easy destemming pepper will also have to pay attention to fruit size and shape.

Estimation of the population at high risk of developing lung cancer in Chile using simplified eligibility criteria.

OBJECTIVES: Several countries in different global regions are implementing lung cancer (LC) screening programmes. This study aimed to estimate the proportion of the Chilean population ≥15 years who are at high risk of developing LC. STUDY DESIGN: Cross-sectional study. METHODS: Data from the Chilean National Health Survey were used in this study. Information on age and history of tobacco consumption were retrieved to estimate national and regional proportions of the Chilean population ≥15 years who are at high risk of developing LC, according to the inclusion criteria in the NELSON trial, NLST trial and USPSTF2021 recommendations. Stratified analyses were performed by sex and quartiles of monthly household income. RESULTS: An estimated 292,158 (2.2%; 95% confidence interval [CI] 1.6-2.8), 174,196 (1.3%; 95% CI 0.9-1.7) and 404,751 (3.1%; 95% CI 2.4-3.8) of Chileans are at high risk of LC according to NELSON and NLST trial inclusion criteria and USPSTF2021 recommendations, respectively. Proportions of males who are at high risk were higher in comparison to females. The highest proportion of people who are at high risk was found in the lowest household income quartile. Regionally, the lowest percentage of Chileans who are at high risk was found in La Araucanía and the highest in Magallanes y Antártica. CONCLUSIONS: There is a relevant number of Chileans who are at high risk of developing LC. Policymakers in Chile should enhance tobacco control efforts to reduce the prevalence of tobacco smoking and also explore the implementation of LC screening programmes to reduce the burden of LC.

Sex Differences in Profile and In-Hospital Death for Acute Stroke in Chile: Data From a Nationwide Hospital Registry.

BACKGROUND: Knowledge of local contextual sex differences in the profile and outcome for stroke can improve service delivery. We aimed to determine sex differences in the profile of patients with acute stroke and their associations with in-hospital death in the national hospital database of Chile. METHODS AND RESULTS: We present a retrospective cohort based on the analysis of the 2019 Chilean database of Diagnosis-Related Groups, which represents 70% of the operational expenditure of the public health system. Random-effects multiple logistic regression models were used to determine independent associations of acute stroke (defined by main diagnosis International Classification of Diseases, Tenth Revision [ICD-10] codes) and in-hospital death, and reported with odds ratios (ORs) and 95% CIs. Of 1 048 575 hospital discharges, 15 535 were for patients with acute stroke (7074 [45.5%] in women), and 2438 (15.6%) of them died during hospitalization. Differences by sex in sociodemographic and clinical characteristics were identified for stroke and main subtypes. After fully adjusted model, women with ischemic stroke had lower in-hospital death (OR, 0.79 [95% CI, 0.69-0.91]) compared with men; other independent predictors included age per year increase (OR, 1.03 [95% CI, 1.03-1.04]), chronic kidney disease (OR, 1.47 [95% CI, 1.20-1.80]), atrial fibrillation (OR, 1.50 [95% CI, 1.26-1.80]), and other risk factors. Conversely, for intracerebral hemorrhage, women had a higher in-hospital mortality rate than men (OR, 1.19 [95% CI, 1.02-1.40]); other independent predictors included age per year increase (OR, 1.009 [95% CI, 1.003-1.01]), chronic kidney disease (OR, 1.55 [95% CI, 1.23-1.97]), oral anticoagulant use (OR, 1.88 [95% CI, 1.37-2.58]), and other risk factors. CONCLUSIONS: Sex differences in characteristics and in-hospital death of hospitalized patients exist for acute stroke in Chile. In-hospital death is higher for acute ischemic stroke in men and higher for intracerebral hemorrhage in women. Future research is needed to better identify contributing factors.

The economics of ethnic marriages: Endogamy and the social status of minority groups.

This study examines the relationship between ethnic endogamy and socioeconomic status (SES) within the socioeconomically divergent Jewish and Native-Chilean Mapuche communities of Santiago, Chile. By leveraging the Hispanic naming convention to analyze dual ethnic surnames, we trace endogamy patterns across comprehensive datasets that go back to 1884 up to the present. Our quantile regression analysis reveals that individuals from the lower SES brackets of the Jewish community and the higher brackets of the Mapuche community are more likely to have mixed ethnic backgrounds. This finding shows a nuanced interplay between socioeconomic standing and marital choices, suggesting that these factors significantly influence the persistence and transformation of SES within minority groups. The study introduces the Ecological Model of Ethnic Disaffiliation, providing a theoretical framework that explains how socioeconomic outliers within ethnic groups could lead to a narrowing of their socioeconomic range over generations.

Does educational attainment matter for attitudes toward immigrants in Chile? Assessing the causality and generalizability of higher education's so-called "liberalizing effect" on economic and cultural threat.

Despite a large literature consistently showing a relationship between higher levels of education and lower levels of ethnic prejudice, some points of contention remain. First, it remains unclear whether education has a causal effect on attitudes, mainly due to a lack of longitudinal studies. Second, due to the majority of studies on prejudice being conducted in Europe and North America, we do not know to what extent the inverse relationship between education and prejudice is generalizable beyond the "global North." To answer these questions, I study attitudes toward immigrants in Chile in the years 2016-2022, using six waves of the Chilean Longitudinal Social Survey. Chile provides new variations in economic and cultural factors, with its stable albeit highly unequal economy, and increased immigration from culturally similar countries which shed light on possible scope conditions of the so-called liberalizing effect of education. I analyze whether attaining more education has an effect on reducing levels of perceived economic and cultural threat. The findings show that increases in education are associated with both lower levels of perceived economic and cultural threat, with education having a stronger effect on the latter.

Do not resuscitate orders and limitation of therapeutic effort: Ethical challenges in healthcare teams in Chile. / Orden de no reanimar y limitación del esfuerzo terapéutico: desafíos éticos en equipos sanitarios en Chile.

The purpose of this paper is to delve into the ethical aspects experienced by the healthcare team when they receive the directive to limit therapeutic effort or a do-not-resuscitate order. From an interpretative, qualitative paradigm with a content analysis approach, a process based on three phases was conducted: pre-analysis in which categories were identified, the projection of the analysis, and inductive analysis. During 2023, interviews were conducted in the clinical setting of a high-complexity hospital in Chile with 56 members of the healthcare teams from critical and emergency units, from which four categories emerged: a) the risk of violating patients' rights by using do-not-resuscitate orders and limiting therapeutic effort; b) the gap in the interpretation of the legal framework addressing the care and attention of patients at the end of life or with terminal illnesses by the healthcare team; c) ethical conflicts in end-of-life care; and d) efficient care versus holistic care in patients with terminal illness. There are significant gaps in bioethics training and aspects of a good death in healthcare teams facing the directive to limit therapeutic effort and not resuscitate. It is suggested to train personnel and work on a consensus guide to address the ethical aspects of a good death.

El propósito de este trabajo es profundizar en los aspectos éticos que experimenta el equipo de salud cuando reciben la indicación de limitar el esfuerzo terapéutico o la orden de no reanimar. Desde un paradigma interpretativo, cualitativo y con un enfoque de análisis de contenido, se realizó un proceso basado en tres fases: preanálisis en el que se identificaron las categorías, la proyección del análisis y el análisis inductivo. Durante 2023, se realizaron entrevistas en el entorno clínico de un hospital de alta complejidad en Chile a 56 miembros de equipos de salud de unidades críticas y urgencias, de las que emergieron cuatro categorías: a) riesgo de vulnerar los derechos de los pacientes al utilizar la orden de no reanimar, y limitación del esfuerzo terapéutico; b) brecha en la interpretación del marco legal que aborda la atención y cuidado de pacientes al final de la vida, o con enfermedades terminales por parte del equipo de salud; c) conflictos éticos de la atención al final de la vida; y d) el cuidado eficiente o el cuidado holístico en pacientes con enfermedad terminal. Existen brechas importantes en la formación en bioética y aspectos del buen morir en los equipos de salud que se enfrentan a la orden de limitar el esfuerzo terapéutico y no reanimar. Se sugiere capacitar al personal, y trabajar una guía de consenso para abordar los aspectos éticos del buen morir.

Socioeconomic Disparities in Urban Forest Diversity and Structure in Green Areas of Santiago de Chile.

Urban trees enhance biodiversity, provide ecosystem services, and improve quality of life in cities. Despite their benefits, trees are not distributed equitably, and many cities exhibit a "luxury effect". Given the importance of public green space for providing access to urban tree benefits, we investigated the relationship between socioeconomic level and tree diversity and structure in 60 green areas in Santiago de Chile. Species richness and total tree abundance did not significantly vary among socioeconomic levels; however, a differential effect was found according to species origin. Introduced tree species exhibited similar abundance and species richness across socioeconomic levels, but native tree species were more abundant and richer in higher socioeconomic level areas compared to lower ones. Tree cover was higher in the high and medium socioeconomic level areas than in the low socioeconomic level area. A higher average DBH was found in the medium socioeconomic level area, which may be explained by older neighborhoods and a legacy of the luxury effect. Our findings reveal that socioeconomic groups are associated with differences in tree cover, width, and the number of native species in public green areas. Consequently, urban residents have different provisions of ecosystem services and opportunities to interact with natural heritage. Increasing the amount of tree cover and native species available to vulnerable groups will reduce disparities.
