The Commoditization of Ecosystems within Chile's Mapuche Territory: A Violation of the Human Right to Health.

The Araucanía region of Chile is characterized by a significant rural Indigenous population-the Mapuche people-who preserve their cultural beliefs about the world around them. This region is also distinguished by the conflict between the Mapuche people and the Chilean government. The Chilean state has supported the development of extractive projects such as industrial plantations, hydroelectric plants, and aquaculture, using nature to generate profits. This has collided with the Mapuche's inextricable relationship with nature and territory, which they value as a spiritual and historical space. Our qualitative study, conducted between 2016 and 2019 in three Araucanía territories with large Mapuche populations, sought to explore Mapuche perceptions of nature, their right to health, Indigenous rights generally, and Indigenous communities' relationship with the state. The results show an overall perception among Mapuche communities of an extractive mentality at the heart of the Chilean state, regardless of the administration in power, as well as a belief that the industrial occupation of their territories represents a process of colonialism and the transgression of ancestral rights. This extractivist approach by the state has caused Mapuche communities to witness enormous changes to their ecosystem, with negative impacts on their well-being.

[Problem-solving in the Indigenous Health Care Subsystem (SASI-SUS): analysis in a reference service in Amazonas, Brazil]. / Resolutividade no Subsistema de Atenção à Saúde Indígena (SASI-SUS): análise em um serviço de referência no Amazonas, Brasil.

Problem-solving is one of the principles of the Unified Health System (SUS) in Brazil, with its ability to solve the health problems of the population at different levels of complexity. The Indigenous Health Care Subsystem (SASI-SUS) is part of this service, respecting the specificities of indigenous populations. The scope of this article is to analyze the perception of professionals and managers of an Indigenous Health Center (CASAI) regarding its ability to cope with the circumstances of the pandemic. It involved qualitative and descriptive research under the National Health Care Policy for Indigenous Peoples (PNASPI) and Paul Ricoeur's hermeneutic theory. Interviews were conducted with participants in order to record the experiences in the work process of the actors who assist the indigenous people housed at CASAI. Four essential themes were identified in the interviews: cultural care; permanent education in health & health education; negotiation & improvisation; and reception & infrastructure. CASAI is an institution that is more than a support center or accommodation, being a crossover point between the different levels of care and knowledge production of the indigenous people, as well as a place for establishing a relationship, resulting in a problem-solving space.

A resolutividade é um dos princípios do Sistema Único de Saúde (SUS) no Brasil, com sua capacidade de resolver os problemas da população nos diferentes níveis de complexidade da saúde. O Subsistema de Atenção à Saúde Indígena (SASI-SUS) integra este sistema, respeitando as especificidades das populações indígenas. O objetivo deste artigo é analisar a percepção dos profissionais e gestores de uma Casa de Saúde Indígena (CASAI) a respeito da resolutividade no subsistema quanto às circunstâncias da pandemia. Pesquisa qualitativa, de caráter descritivo, à luz da Política Nacional de Atenção à Saúde dos Povos Indígenas (PNASPI) e da teoria hermenêutica de Paul Ricoeur. Foram realizadas entrevistas entre os participantes a fim de registrar as experiências no processo de trabalho dos atores que cuidam dos indígenas referenciados à Manaus, Amazonas. Foram identificadas, pelas entrevistas, quatro temáticas essenciais: cuidado cultural; educação permanente em saúde & educação em saúde; negociação & improviso e; acolhimento & infraestrutura. A CASAI é uma instituição que vai além de um centro de apoio ou alojamento, sendo ponto de articulação entre os diferentes níveis de atenção aos indígenas e local de produção de cuidados e de saberes, tal como da construção de suas relações, resultando em um espaço resolutivo.

Resolutividade no Subsistema de Atenção à Saúde Indígena no Brasil: revisão de escopo / Resolubility in the Indigenous Health Care Subsystem in Brazil: scope review / Resolución en el Subsistema de Atención de la Salud Indígena en Brasil: revisión del alcance

RESUMO: A resolutividade relaciona-se à capacidade de solução dos problemas de saúde nos serviços. Em 1999, o Subsistema de Atenção à Saúde Indígena foi integrado ao Sistema Único de Saúde no Brasil, passando a seguir os seus princípios e diretrizes. Este estudo teve por objetivo identificar e mapear os desafios ou problemas relacionados às práticas em saúde para a resolutividade no Subsistema de Saúde Indígena após a integração. Trata-se de uma revisão de escopo que utilizou seis bases de dados nacionais e internacionais. Os estudos elegíveis tiveram como critério base o mnemônico PCC (P: população indígena; C: desafios ou problemas para a resolutividade; C: subsistema de saúde indígena brasileiro). Foram encontrados 1.748 estudos e selecionados 33, com predomínio de estudos qualitativos. Os desafios ou problemas sensíveis para o processo da resolutividade foram encontrados nos aspectos que tangem à educação em saúde, à interculturalidade, ao acesso universal e aos recursos em gestão. O saber tradicional é pouco valorizado pelo sistema de saúde. A deficiência de recursos humanos e materiais, a falta de efetiva educação permanente e de capacitações para trabalhar no contexto intercultural produzem barreiras de acesso e comprometem a resolutividade nos serviços, aumentando assim as iniquidades em saúde.

ABSTRACT: Resolubility relates to the ability to solve health problems in services. In 1999, the Indigenous Health Care Subsystem was integrated into the Brazilian Unified Health System, following its principles and guidelines. The objective of this study was to identify and map the challenges or problems related to health practices for solving in the Indigenous Health Subsystem after integration. This is a scope review that used six national and international databases. Eligible studies were based on mnemonic PCC (P: indigenous population; C: challenges or problems for resolution; C: Brazilian indigenous health subsystem). A total of 1,748 studies were found and 33 were selected, with predominance of qualitative studies. The challenges or problems that are sensitive to the resolution process were found in the aspects that are related to health education, interculturality, universal access and management resources. Traditional knowledge is underrated by the health system. The deficiency of human and material resources, the lack of effective permanent education and capacitations to work in the intercultural context, produce barriers to access and compromise the resolubility in services, thus increasing the inequities in health.

Molecular Epidemiology in Amerindians of the Brazilian Amazon Reveals New Genetic Variants in DNA Repair Genes.

Native American populations from the Brazilian Amazon have a low genetic diversity and a different genetic profile when compared to people from other continents. Despite this, few studies have been conducted in this group, and there is no description of their genetic data in the various currently existent international databases. The characterization of the genomic profile of a population not only has an impact in studies of population genetics, but also helps to advance diagnostic and therapeutic response studies, leading to the optimization of clinical applicability. Genetic variations in DNA repair genes have been associated with the modulation of susceptibility to various pathologies, as well as in their prognosis and therapy. This is the first study to investigate DNA repair genes in Amerindians from the Brazilian Amazon region. We investigated 13 important DNA repair genes in the exome of 63 Native Americans, comparing our results with those found in 5 continental populations, whose data are available in the Genome Aggregation Database. Our results showed that 57 variants already described in literature were differentially distributed in the Amerindian populations in relation to the continental populations, 7 of which have significant clinical relevance. In addition, 9 new variants were described, suggesting that they are unique to these populations. Our study reinforces the understanding that the Amazonian Native American population presents a unique genetic profile, and our findings may collaborate with the creation of public policies that optimize the quality of life of these groups as well as the Brazilian population, which presents a high degree of interethnic mixing with Amerindian groups.

Las epidemias en La Pampa (Argentina), en perspectiva histórica* / The epidemics in La Pampa (Argentina), from a historical perspective

Resumen Este artículo describe el inicio de las preocupaciones sanitarias vinculadas a las epidemias ocurridas durante el siglo XX en La Pampa, provincia argentina. Las epidemias, como las de la viruela, fueron un estímulo para estas políticas que frecuentemente tuvieron origen en Buenos Aires, la capital del país. El contagio de muchas epidemias dependía de carencias de infraestructura: agua, desagüe y desecho adecuado de basuras, de la ausencia de un número suficiente de trabajadores de salud, de la presencia de vectores transmisores de enfermedades como los mosquitos y, en última instancia, de la pobreza. La experiencia histórica descrita en este texto resalta la importancia de analizar el impacto del SARS-CoV-2 más allá de las grandes ciudades.

Abstract This article describes the emergence of health concerns relating to the epidemics that occurred during the twentieth century in La Pampa, a province in Argentina. Epidemics such as smallpox drove such policies, which frequently originated in Buenos Aires, the country's capital. The spread of many epidemics was due to shortages: water, sewage and adequate refuse disposal, an insufficient number of health care workers, the presence of disease transmission vectors such as mosquitos, and, ultimately, poverty. The historical experience described in this text highlights the importance of analyzing the impact of SARS-CoV-2 beyond the big cities.

Do wealth and inequality associate with health in a small-scale subsistence society?

In high-income countries, one's relative socio-economic position and economic inequality may affect health and well-being, arguably via psychosocial stress. We tested this in a small-scale subsistence society, the Tsimane, by associating relative household wealth (n = 871) and community-level wealth inequality (n = 40, Gini = 0.15-0.53) with a range of psychological variables, stressors, and health outcomes (depressive symptoms [n = 670], social conflicts [n = 401], non-social problems [n = 398], social support [n = 399], cortisol [n = 811], body mass index [n = 9,926], blood pressure [n = 3,195], self-rated health [n = 2523], morbidities [n = 1542]) controlling for community-average wealth, age, sex, household size, community size, and distance to markets. Wealthier people largely had better outcomes while inequality associated with more respiratory disease, a leading cause of mortality. Greater inequality and lower wealth were associated with higher blood pressure. Psychosocial factors did not mediate wealth-health associations. Thus, relative socio-economic position and inequality may affect health across diverse societies, though this is likely exacerbated in high-income countries.

Poverty is bad for health. People living in poverty are more likely to struggle to afford nutritious food, lack access to health care, or be overworked or stressed. This may make them susceptible to chronic diseases, contribute to faster aging, and shorten their lifespans. In high-income countries, there is growing evidence to suggest that a person's 'rank' in society also impacts their health. For example, individuals who have a lower position in the social hierarchy report worse health outcomes, regardless of their incomes. But it is unclear why living in an unequal society or having a lower social status contributes to poorer health. One possibility is that inequalities in society are creating a stressful environment that leads to worse physical and mental outcomes. It is thought that this stress largely comes from how humans evolved to prioritize reaching a higher social status over having a long and healthy life. If this is the case, this would mean that the link between social status and health would also be present in non-industrialized communities where social hierarchies tend to be less pronounced. To test this, Jaeggi, Blackwell et al. studied the Indigenous Tsimane population in Bolivia who live in small communities and forage and farm their own food. The income and relative wealth of 870 households from 40 Tsimane communities were compared against various outcomes, including symptoms associated with depression, stress hormone levels, blood pressure, self-rated health and several diseases. Jaeggi, Blackwell et al. found poverty and inequality did not negatively impact all of the health outcomes measured as has been previously reported for industrialized societies. However, blood pressure was higher among people with lower incomes or those who lived in more unequal communities. But because the Tsimane people generally have low blood pressure, the differences were too small to have much effect on their health. People who lived in more unequal communities were also three times more likely to have respiratory infections, but the reason for this was unclear. This shows that social determinants such as a person's wealth or inequality can affect health, even in communities with less rigid social hierarchies. In industrial societies the effect may be worse in part because they are compounded by lifestyle factors, such as diets rich in fat and sugar, and physical inactivity which can also increase blood pressure. This information may help policy makers reduce health disparities by addressing some of the social determinants of health and the lifestyle factors that cause them.

Perceptions of Ecuadorian indigenous healers on their relationship with the formal health care system: barriers and opportunities.

BACKGROUND: The new paradigm of intercultural policies focuses on rethinking the common public culture. In Ecuador, the "Buen Vivir" plan seeks to incorporate the ancestral medical knowledge, experience and beliefs of traditional healers into the formal health services. This study explores views on the formal health system from the perspective of the healers belonging to the Kichwa and Shuar ethnicities in the South of Ecuador. METHODS: A qualitative study with a phenomenological approach was performed. Focus groups were conducted in three locations in Southern Ecuador. Shuar, Kichwa and Mestizo ethnic groups were included in the research. RESULTS: Eleven focus groups with a total of 110 participants belonging to the Shuar, Kichwa and Mestizo ethnic groups participated in the study. Six themes were created through analysis: 1) conflicts with health professionals, 2) acceptance of traditional healers, 3) respect, 4) work as a team, 5) environment and patient care, and 6) salary and recognition. CONCLUSION: This study indicated the perceived barriers compromising respectful collaboration between health staff and traditional healers from an indigenous perspective. Power inequalities and a historically unidirectional relationship and, in addition, differences in health beliefs, seem to create misunderstandings regarding each other's approach when faced with health and disease. However, insight in these barriers can create opportunities towards collaboration, which will have a positive effect on patient confidence in one or both systems and support continuity between traditional healers and the formal health system.

Newborn anthropometry, maternal capital, and altitude in the highland population from the province of Jujuy, Argentina.

OBJECTIVE: To analyze variability in newborn (NB) anthropometry among Jujenean NBs as a function of geographic altitude (500 m to ≈4000 masl), maternal anthropometry and other maternal characteristics within the maternal capital framework. MATERIALS AND METHODS: Data obtained from 41,371 mother/child pairs recorded in the Jujuy Perinatal Information System (SIP) between 2009 and 2014, including: NB and maternal weight, length/height and BMI; gestational age (corrected); maternal age, educational level, nutritional status, and marital status; birth interval; and planned pregnancy. Based on the declared place of residence, the prevalence of unsatisfied basic needs (% UBN) was determined and the data was split into two altitudinal groups: highlands (HL, >2500 masl) and lowlands (LL, <2500 masl). ANOVA, Chi-squared and Pearson tests were applied as needed. Statistical associations between the response variables-NB weight, length and BMI-and maternal and environmental variables were tested using a Generalized Additive Mixed Model (GAMM). RESULTS: All NB and maternal anthropometric variables were lower in HL compared to LL; they also presented negative correlations with altitude, except NB length. Apart from gestational age and birth interval, HL and LL presented statistically significant differences in all study variables. GAMM results showed that maternal anthropometry was the main influence on NB weight and length. DISCUSSION: Of all the maternal capital features examined, only maternal anthropometric variables were found to protect offspring against the negative impact of HL environments.

Changing Home: Experiences of the Indigenous when Receiving Care in Hospital.

OBJECTIVES: To understand the meaning of the experience of the indigenous when receiving care in a low-complexity hospital. METHODS: Qualitative study with ethnographic approach conducted in a hospital of Antioquia, Colombia. The study had 12 indigenous participants who underwent semi-structured interviews. Observation was carried out in hospitalization wards, emergency, and outpatient services of the institution during 40 hours. The analysis process was performed descriptively. The methodological rigor was maintained by applying criteria of confirmability, credibility, transferability, and consistency. The study was approved by the Ethics Committee and authorized by the indigenous authorities to enter the field. RESULTS: Five themes emerged: the context of caring for the indigenous, the need to consult the hospital, changes experienced by the indigenous in the hospital, experiences in relation with treatments, and relations established within the hospital. The meaning is constructed from a dichotomous perspective based on the favorable or unfavorable aspects of the situations and experiences, which for the indigenous is like "changing home". CONCLUSIONS: The meaning of the experience of receiving care in hospital for the indigenous is constructed from the context in which they live and receive health services, the changes they live in the dimension of space by virtue of their traveling from their vital space to another space that, due to their physical characteristics, results strange and different, even not healing. Upon the difficulties, the indigenous develop strategies and actions to overcome limitations, whether through adaptation and learning.

[Profile of antineoplastic medication among indigenous people treated in the Brazilian Unified National Health System]. / Perfil de utilização de medicamentos antineoplásicos entre indígenas atendidos pelo Sistema Único de Saúde.

Brazil has an estimated 900,000 indigenous people (0.4% of the country's population), belonging to more than 300 different ethnic groups. However, information is scarce on cancer epidemiology and the antineoplastic drugs used in treatment of these individuals. The study's objectives are to identify the antineoplastic drugs used and to describe the profile of use of these drugs in the indigenous population treated in Brazil, as well as to describe the patients' epidemiological profile. An ecological study was performed involving outpatient chemotherapy care from January 2014 to December 2018 throughout Brazil. The data source was the Outpatient Information System of the Brazilian Health Informatics Department, considering only Authorizations for High-Complexity Chemotherapy Procedures. We identified 2,425 authorizations for chemotherapy procedures for treatment of indigenous patients. Of these, 2,292 authorizations for a total of 210 individuals were analyzed. We found an increase in the number of authorizations and of indigenous persons receiving chemotherapy over the period, with a higher concentration of individuals living in and receiving treatment in the South of Brazil, plus a wide diversity in the types of diagnosed tumors (n = 63) and of treatment regimen used during the treatment (n = 107). The current study provided a new overview of the epidemiological profile of indigenous patients receiving chemotherapy in the Brazilian Unified National Health System. The findings help fill a current knowledge gap on indigenous people's health in Brazil.

Estima-se que no Brasil existam cerca de 900 mil indígenas (0,4% da população do país) pertencentes a mais de 300 etnias diferentes. Porém, informações sobre a epidemiologia do câncer e sobre os medicamentos antineoplásicos utilizados no tratamento desses indivíduos são escassas. Os objetivos do presente estudo são identificar os medicamentos antineoplásicos utilizados e descrever o perfil de utilização deles na população indígena tratada no Brasil, além de descrever o perfil epidemiológico dos usuários. Foi realizado um estudo do tipo ecológico que envolveu os atendimentos ambulatoriais de quimioterapia, realizados no período de janeiro de 2014 e dezembro de 2018, em todo o Brasil. A fonte de coleta dos dados utilizada foi o Sistema de Informação Ambulatorial, do Departamento de Informática do SUS, considerando apenas as Autorizações de Procedimentos de Alta Complexidade para Quimioterapia. Foram identificadas 2.425 autorizações para procedimentos de quimioterapia destinadas ao tratamento de pacientes indígenas. Um total de 2.292 autorizações, para um total de 210 indivíduos, foram analisadas. Observou-se um aumento do número de autorizações e de indígenas em uso de quimioterapia ao longo do período, maior concentração de indivíduos residentes e em tratamento na Região Sul do país, diversidade de tipos de tumores diagnosticados (n = 63) e de esquemas terapêuticos utilizados durante o tratamento (n = 107). O presente estudo trouxe um novo panorama sobre o perfil epidemiológico dos usuários indígenas sob tratamento quimioterápico no Sistema Único de Saúde. Os achados contribuem para o preenchimento da atual lacuna de conhecimento a respeito da saúde indígena no Brasil.

Genetic assessment reveals no population substructure and divergent regional and sex-specific histories in the Chachapoyas from northeast Peru.

Many native populations in South America have been severely impacted by two relatively recent historical events, the Inca and the Spanish conquest. However decisive these disruptive events may have been, the populations and their gene pools have been shaped markedly also by the history prior to the conquests. This study focuses mainly on the Chachapoya peoples that inhabit the montane forests on the eastern slopes of the northern Peruvian Andes, but also includes three distinct neighboring populations (the Jívaro, the Huancas and the Cajamarca). By assessing mitochondrial, Y-chromosomal and autosomal diversity in the region, we explore questions that have emerged from archaeological and historical studies of the regional culture (s). These studies have shown, among others, that Chachapoyas was a crossroads for Coast-Andes-Amazon interactions since very early times. In this study, we examine the following questions: 1) was there pre-Hispanic genetic population substructure in the Chachapoyas sample? 2) did the Spanish conquest cause a more severe population decline on Chachapoyan males than on females? 3) can we detect different patterns of European gene flow in the Chachapoyas region? and, 4) did the demographic history in the Chachapoyas resemble the one from the Andean area? Despite cultural differences within the Chachapoyas region as shown by archaeological and ethnohistorical research, genetic markers show no significant evidence for past or current population substructure, although an Amazonian gene flow dynamic in the northern part of this territory is suggested. The data also indicates a bottleneck c. 25 generations ago that was more severe among males than females, as well as divergent population histories for populations in the Andean and Amazonian regions. In line with previous studies, we observe high genetic diversity in the Chachapoyas, despite the documented dramatic population declines. The diverse topography and great biodiversity of the northeastern Peruvian montane forests are potential contributing agents in shaping and maintaining the high genetic diversity in the Chachapoyas region.

The genetic structure and adaptation of Andean highlanders and Amazonians are influenced by the interplay between geography and culture.

Western South America was one of the worldwide cradles of civilization. The well-known Inca Empire was the tip of the iceberg of an evolutionary process that started 11,000 to 14,000 years ago. Genetic data from 18 Peruvian populations reveal the following: 1) The between-population homogenization of the central southern Andes and its differentiation with respect to Amazonian populations of similar latitudes do not extend northward. Instead, longitudinal gene flow between the northern coast of Peru, Andes, and Amazonia accompanied cultural and socioeconomic interactions revealed by archeology. This pattern recapitulates the environmental and cultural differentiation between the fertile north, where altitudes are lower, and the arid south, where the Andes are higher, acting as a genetic barrier between the sharply different environments of the Andes and Amazonia. 2) The genetic homogenization between the populations of the arid Andes is not only due to migrations during the Inca Empire or the subsequent colonial period. It started at least during the earlier expansion of the Wari Empire (600 to 1,000 years before present). 3) This demographic history allowed for cases of positive natural selection in the high and arid Andes vs. the low Amazon tropical forest: in the Andes, a putative enhancer in HAND2-AS1 (heart and neural crest derivatives expressed 2 antisense RNA1, a noncoding gene related to cardiovascular function) and rs269868-C/Ser1067 in DUOX2 (dual oxidase 2, related to thyroid function and innate immunity) genes and, in the Amazon, the gene encoding for the CD45 protein, essential for antigen recognition by T and B lymphocytes in viral-host interaction.

Covid-19 pandemic and the motivations for demanding health service in indigenous villages.

OBJECTIVE: To discuss the fundamental aspects in the establishment of preventive measures to tackle covid-19 among indigenous people in view of the motivations for seeking health care in villages of the Terra Indígena Buriti, Mato Grosso do Sul, Brazil. METHODS: Theoretical-reflective study based on assumptions of the National Health System and previous ethnographic research that enabled the identification of the motivations to seek health care in Buriti villages. RESULTS: Indigenous people seek health centers for health care programs assistance, treatment of cases they cannot resolve and to chat. Such motivations were the basis for discussing the indigenization process in the confrontation of the new coronavirus pandemic in indigenous lands. FINAL CONSIDERATIONS: The motivations for seeking health care show the physical and social vulnerability of the Terena ethnicity. The effectiveness of the social isolation measure in the villages depends on the dialogue with indigenous leaders, professional engagement and intersectoral actions.

Population-level assessment of atlas occipitalization in artificially modified crania from pre-Hispanic Peru.

Atlas occipitalization (AO) is a spinal anomaly, characterized by the fusion of the first cervical vertebra and occipital bone, with a complex etiology that can arise from congenital and environmental causes. AO has been reported in three regions of pre-Hispanic Peru in skeletal remains with artificial cranial modification (ACM), which involves the use of compression devices to permanently alter cranial shape and may have affected the fusion of the atlas and occipital bone. The aims of this study were to gain insights into AO's etiology by testing correlations between AO and ACM presence/type and geographic region as well as to characterize morphological variation associated with AO. We investigated the geographic distribution of AO and its potential relationship to ACM in a large sample of human crania from eight coastal and highland regions of pre-Hispanic Peru, held at the Smithsonian's National Museum of Natural History (n = 608, 1300-1500 CE). Eleven cases of AO were observed in three coastal regions-including two previously unreported regions-at an overall frequency of 1.8%. The frequency of AO did not differ significantly between crania with and without ACM, in general or by type, suggesting that ACM is not an etiological factor that influences AO in this sample. AO was observed at a significantly higher rate in the southern coastal region of Arequipa than in any other region. Genetic, dietary, and epidemiological conditions are evaluated as factors possibly shaping the geographic distribution of AO along the central and southern coasts of Peru.
