ABSTRACT
Despite their ancient past and high diversity, African populations are the least represented in human population genetic studies. In this study, uniparental markers (mtDNA and Y chromosome) were used to investigate the impact of sociocultural factors on the genetic diversity and inter-ethnolinguistic gene flow in the three major Nigerian groups: Hausa (n = 89), Yoruba (n = 135) and Igbo (n = 134). The results show a distinct history from the maternal and paternal perspectives. The three Nigerian groups present a similar substrate for mtDNA, but not for the Y chromosome. The two Niger-Congo groups, Yoruba and Igbo, are paternally genetically correlated with populations from the same ethnolinguistic affiliation. Meanwhile, the Hausa is paternally closer to other Afro-Asiatic populations and presented a high diversity of lineages from across Africa. When expanding the analyses to other African populations, it is observed that language did not act as a major barrier to female-mediated gene flow and that the differentiation of paternal lineages is better correlated with linguistic than geographic distances. The results obtained demonstrate the impact of patrilocality, a common and well-established practice in populations from Central-West Africa, in the preservation of the patrilineage gene pool and in the affirmation of identity between groups.

Blood selenium (Se) concentrations differ substantially by population and could be influenced by genetic variants, increasing Se deficiency-related diseases. We conducted a genome-wide association study (GWAS) to identify single nucleotide polymorphisms (SNPs) associated with serum Se deficiency in 382 adults with admixed ancestry. Genotyping arrays were combined to yield 90,937 SNPs. R packages were applied to quality control and imputation. We also performed the ancestral proportion analysis. The Search Tool for the Retrieval of Interacting Genes was used to interrogate known protein-protein interaction networks (PPIs). Our ancestral proportion analysis estimated 71% of the genome was from Caucasians, 22% was from Africans, and 8% was from East Asians. We identified the SNP rs1561573 in the TraB domain containing 2B (TRABD2B), rs425664 in MAF bZIP transcription factor (MAF), rs10444656 in spermatogenesis-associated 13 (SPATA13), and rs6592284 in heat shock protein nuclear import factor (HIKESHI) genes. The PPI analysis showed functional associations of Se deficiency, thyroid hormone metabolism, NRF2-ARE and the Wnt pathway, and heat stress. Our findings show evidence of a genetic association between Se deficiency and metabolic pathways indirectly linked to Se regulation, reinforcing the complex relationship between Se intake and the endogenous factors affecting the Se requirements for optimal health.

This article discusses the origin of quijila/kijila in Central West African culture, more particularly in the cultural universe of the Imbangala (Jaga) and the Ambundu and Kimbundu populations who lived in the Portuguese regions of Angola and the Congo in the seventeenth and eighteenth centuries. Following this, it investigates how the concept of quijila was structured, comprehended, and transformed, both in Africa, where it was basically a food prohibition, but whose applications and meanings varied; and in Brazil, to where it was transported in the 1700s, and where it transformed into a disease which attacked blacks, especially Africans of various origins, being framed as such in the Hippocratic-Galen universe characteristic of that time.
Este artigo discute a origem da quijila/kijila na cultura centro-ocidental africana, mais particularmente no universo cultural dos imbangalas (jagas) e das populações ambundos e kimbundos, que viviam nas regiões portuguesas de Angola e do Congo, nos séculos XVII e XVIII. Em seguida, investiga como foi estruturado, compreendido e transformado o conceito de quijila tanto na África, basicamente um interdito alimentar, mas cujos significados e aplicações variam, quanto no Brasil, para onde foi transportado nos Setecentos, transformando-se numa doença que atacava os negros, especialmente os africanos de diversas origens, sendo enquadrada pelos médicos locais no universo da medicina hipocrática-galena vigente na época.

Brazilian quilombos are communities formed by enslaved Africans and their descendants all over the country during slavery and shortly after its abolition. Quilombos harbor a great fraction of the largely unknown genetic diversity of the African diaspora in Brazil. Thus, genetic studies in quilombos have the potential to provide important insights not only into the African roots of the Brazilian population but also into the genetic bases of complex traits and human adaptation to diverse environments. This review summarizes the main results of genetic studies performed on quilombos so far. Here, we analyzed the patterns of African, Amerindian, European, and subcontinental ancestry (within Africa) of quilombos from the five different geographic regions of Brazil. In addition, uniparental markers (from the mtDNA and the Y chromosome) studies are analyzed together to reveal demographic processes and sex-biased admixture that occurred during the formation of these unique populations. Lastly, the prevalence of known malaria-adaptive African mutations and other African-specific variants discovered in quilombos, as well as the genetic bases of health-related traits, are discussed here, together with their implication for the health of populations of African descent.

O texto é um relato de experiência da participação no Grupo de Estudos psicoQuilombologia ocorrida nos meses de setembro de 2020 a março de 2021, período atravessado pela segunda onda da pandemia de COVID-19 no Brasil. O objetivo do relato é apresentar o conceito-movimento de psicoQuilombologia como uma proposta epistemológica quilombola de agenciamento de cuidado e saúde, com base em uma escuta que se faça descolonial e inspirada no fecundo e ancestral acervo de cuidado dos povos africanos, quilombolas e pretos, preservado e atualizado em nossos quilombos contemporâneos. A metodologia utilizada é a escrevivência, método desenvolvido por Conceição Evaristo que propõe uma escrita em que as vivência e memórias estão totalmente entrelaçadas, imersas e imbricadas com a pesquisa. O resultado das escrevivências dessa pesquisa descortinam que os povos pretos desenvolveram práticas de cuidado e acolhimento às vulnerabilidades do outro, enraizadas no fortalecimento de laços e conexões coletivas de afetos e cuidado mútuos. Práticas de cuidado que articulam memória, ancestralidade, tradição, comunidade, transformação, luta, resistência e emancipação, engendrando modos coletivos de ser e viver. Nas quais cuidar do outro implica tratar suas relações e situar o cuidado como extensão de uma cura que se agencia no coletivo. O trabalho conclui apontando que o cenário pandêmico vigente acentua a pungência de se desenvolver estratégias de cuidado baseadas em epistemologias pretas e quilombolas, valorizando os sentidos de ancestralidade, comunidade, pertencimento e emancipação.(AU)
The text is an experience report of the participation in the psicoQuilombology Study Group that carried out from September 2020 to March 2021, during the second wave of the COVID-19 pandemic in Brazil. The purpose of the report is to introduce the concept-movement of psicoQuilombology as a quilombola epistemological proposal for the development of care and health, based on a decolonial listening and inspired by the rich care collection of African peoples, quilombolas and Blacks, preserved and updated in our contemporary quilombos. The methodology used is writexperience [escrevivências], a method developed by Conceição Evaristo who proposes a writing in that the experiences and memories are totally involved with the research. The result of the writability of this research show that Black people have developed practices of care and acceptance of the other's vulnerabilities, based on the strengthening of ties and collective connections of mutual affection and care. Care practices that mix memory, ancestry, tradition, community, transformation, struggle, resistance and emancipation, outlining collective ways of being and living. The core idea is that taking care of the other means treating your relationships and maintaining care as an extension of a cure that takes place in the collective. The paper concludes by pointing out that the current pandemic scenario demonstrates the urgent need to develop care strategies based on black and quilombola epistemologies, valuing the senses of ancestry, community, belonging and emancipation.(AU)
Este es un reporte de experiencia de la participación en el Grupo de Estudio psicoQuilombología que ocurrió en los meses de septiembre de 2020 a marzo de 2021, periodo en que Brasil afrontaba la segunda ola de la pandemia de la COVID-19. Su propósito es presentar el concepto-movimiento de psicoQuilombología como una propuesta epistemológica quilombola para el desarrollo del cuidado y la salud, basada en una escucha decolonial e inspirada en el rico acervo asistencial de los pueblos africanos, quilombolas y negros, conservado y actualizado en nuestros quilombos contemporáneos. La metodología utilizada es la escrivivencia, un método desarrollado por Conceição Evaristo quien propone una escrita en que las vivencias y los recuerdos están totalmente involucrados con la investigación. El resultado de la escrivivencia muestra que las personas negras han desarrollado prácticas de cuidado y aceptación de las vulnerabilidades del otro, basadas en el fortalecimiento de lazos y conexiones colectivas de afecto y cuidado mutuos. Prácticas de cuidado que mezclan memoria, ascendencia, tradición, comunidad, transformación, lucha, resistencia y emancipación, perfilando formas colectivas de ser y vivir. El cuidar al otro significa tratar sus relaciones y mantener el cuidado como una extensión de una cura que tiene lugar en lo colectivo. El trabajo concluye que el actual escenario pandémico demuestra la urgente necesidad de desarrollar estrategias de atención basadas en epistemologías negras y quilombolas, y que valoren los sentidos de ascendencia, comunidad, pertenencia y emancipación.(AU)

No decorrer da história, sempre foram infindáveis os casos em que os sujeitos recorriam a centros espíritas ou terreiros de religiões de matrizes africanas em decorrência de problemas como doenças, desempregos ou amores mal resolvidos, com o objetivo de saná-los. Por conta disso, este artigo visa apresentar os resultados da pesquisa relacionados ao objetivo de mapear os processos de cuidado em saúde ofertados em três terreiros de umbanda de uma cidade do litoral piauiense. Para isso, utilizamos o referencial da Análise Institucional "no papel". Os participantes foram três líderes de terreiros e os respectivos praticantes/consulentes dos seus estabelecimentos religiosos. Identificamos perspectivas de cuidado que se contrapunham às racionalidades biomédicas, positivistas e cartesianas, e faziam referência ao uso de plantas medicinais, ao recebimento de rezas e passes e à consulta oracular. A partir desses resultados, podemos perceber ser cada vez mais necessário, portanto, que os povos de terreiros protagonizem a construção, implementação e avaliação das políticas públicas que lhe sejam específicas.(AU)
In history, there have always been endless cases of people turning to spiritual centers or terreiros of religions of African matrices due to problems such as illnesses, unemployment, or unresolved love affairs. Therefore, this article aims to present the research results related to the objective of mapping the health care processes offered in three Umbanda terreiros of a city on the Piauí Coast. For this, we use the Institutional Analysis reference "on Paper." The participants were three leaders of terreiros and the respective practitioners/consultants of their religious establishments. We identified perspectives of care that contrasted with biomedical, positivist, and Cartesian rationalities and referred to the use of medicinal plants, the prescript of prayers and passes, and oracular consultation. From these results, we can see that it is increasingly necessary, therefore, that the peoples of the terreiros lead the construction, implementation, and evaluation of public policies that are specific to them.(AU)
A lo largo de la historia, siempre hubo casos en los cuales las personas buscan en los centros espíritas o terreros de religiones africanas la cura para sus problemas, como enfermedades, desempleo o amoríos mal resueltos. Por este motivo, este artículo pretende presentar los resultados de la investigación con el objetivo de mapear los procesos de cuidado en salud ofrecidos en tres terreros de umbanda de una ciudad del litoral de Piauí (Brasil). Para ello, se utiliza el referencial del Análisis Institucional "en el Papel". Los participantes fueron tres líderes de terreros y los respectivos practicantes / consultivos de los establecimientos religiosos que los mismos conducían. Se identificaron perspectivas de cuidado que se contraponían a las racionalidades biomédicas, positivistas y cartesianas, y hacían referencia al uso de plantas medicinales, al recibimiento de rezos y pases y a la consulta oracular. Los resultados permiten concluir que es cada vez más necesario que los pueblos de terreros sean agentes protagónicos de la construcción, implementación y evaluación de las políticas públicas destinadas específicamente para ellos.(AU)
