We report a case of non-affective psychosis with a brief discussion of the phenomenology and its characterization and treatment by traditional Inka healers and eventually by Western-trained psychiatrists. Traditional Inka psychopathology provided empirical support for the transcultural stability of the Kraepelinian dichotomy.

OBJECTIVE: The World Health Organization Atlas Project identified important deficiencies in world mental and neurological health resources. These deficiencies, especially evident in low and middle-income countries, can be overcome by improving research capacity. The objective of this study is to assess the status of mental and neurological research in Latin American countries and identify the main difficulties encountered in conducting research, publishing results, and shaping health policies, interventions, and programs. METHOD: Semi-structured interviews were conducted with 34 key informants from 13 Latin American countries. RESULTS: Participants reported that production of mental and neurological research in Latin American countries is low. Lack of financial and human resources, including lack of support from government agencies, were identified as the main factors contributing to the dearth of local research. The few research projects that do take place in Latin American countries are often funded at researchers' personal expense. Few policies, interventions, or programs are generated from research results. To address these deficiencies, participants called for training in research methodology, mechanisms for identifying funding opportunities, and greater recognition of their research products. CONCLUSIONS: Researchers and stakeholders recognize the need to mobilize local and international efforts aimed at strengthening research capacity and results implementation. This will lead to an overall optimization of mental and neurological research in the region. ; OBJETIVO: El proyecto Atlas de la Organización Mundial de la Salud identifica importantes deficiencias en salud mental y neurológica. Estas deficiencias, especialmente evidentes en países de medianos y bajos ingresos, pueden resolverse mejorando las capacidades en investigación. El objetivo de este estudio es evaluar el estado de la investigación en salud mental y neurológica en países Latinoamericanos, e identificar las principales dificultades encontradas al hacer investigación, publicar resultados, y generar políticas, intervenciones, y programas. MÉTODO: Entrevistas semi-estructuradas fueron realizadas a 34 informantes de 13 países Latinoamericanos. RESULTADOS: La producción de investigación en salud mental y neurológica en países Latinoamericanos es escasa, debido principalmente a la carencia de recursos financieros y humanos, incluyendo el casi ausente apoyo de agencias gubernamentales. Los pocos proyectos de investigación que se llevan a cabo son financiados mayormente con recursos propios de los investigadores. Pocas políticas, intervenciones o programas son generados a partir de resultados de investigación. Resolver estas deficiencias requerirá entrenar profesionales en metodología de la investigación, identificar oportunidades de financiación y lograr un mayor reconocimiento de los productos de la investigación. CONCLUSIONES: Hay necesidad de movilizar esfuerzos locales e internacionales orientados a fortalecer las capacidades en investigación y la implementación de resultados. Esto llevará a una optimización general de la investigación. ; Universidad Peruana Cayetano Heredia Facultad de Ciencias y Filosofía Laboratorios de Investigación y Desarrollo ; Universidad Peruana Cayetano Heredia Facultad de Salud Pública ; Mayo Clinic College of Medicine Department of Psychiatry and Psychology ; Universidade Federal de São Paulo (UNIFESP) Department of Psychiatry ; University of London King's College, Institute of Psychiatry ; Universidad Peruana Cayetano Heredia Facultad de Medicina ; UNIFESP, Department of Psychiatry ; SciELO

Abstract Background Research evidence is essential to inform policies, interventions and programs, and yet research activities in mental and neurological (MN) health have been largely neglected, particularly in low- and middle-income countries. Many challenges have been identified in the production and utilization of research evidence in Latin American countries, and more work is needed to overcome this disadvantageous situation. This study aims to address the situation by identifying initiatives that could improve MN health research activities and implementation of their results in the Latin American region. Methods Thirty-four MN health actors from 13 Latin American countries were interviewed as part of an initiative by the Global Forum for Health Research and the World Health Organization to explore the status of MN health research in low- and middle-income countries in Africa, Asia and Latin-America. Results A variety of recommendations to increase MN health research activities and implementation of their results emerged in the interviews. These included increasing skilled human resources in MN health interventions and research, fostering greater participation of stakeholders in the generation of research topics and projects, and engendering the interest of national and international institutions in important MN health issues and research methodologies. In the view of most participants, government agencies should strive to have research results inform the decision-making process in which they are involved. Thus these agencies would play a key role in facilitating and funding research. Participants also pointed to the importance of academic recognition and financial rewards in attracting professionals to primary and translational research in MN health. In addition, they suggested that institutions should create intramural resources to provide researchers with technical support in designing, carrying out and disseminating research, including resources to improve scientific writing skills. Conclusion Fulfillment of these recommendations would increase research production in MN health in Latin American countries. This, in turn, will raise the profile of these health problems, and consequently will underscore the need of continued high-quality and relevant research, thus fostering a virtuous cycle in the decision-making process to improve MN health care.

Background: The geographical distribution of genes plays a key role in genetic epidemiology. The Chilean population has three major stem groups (Native American, European and African). Aim: To estimate the regional rate of American, European and African admixture of the Chilean population. Subjects and Methods: Forty single nucleotide polymorphisms (SNP ́s) which exhibit substantially different frequencies between Amerindian populations (ancestry-informative markers or AIM ́s), were genotyped in a sample of 923 Chilean participants to estimate individual genetic ancestry. Results: The American, European and African individual average admixture estimates for the 15 Chilean Regions were relatively homogeneous and not statistically different. However, higher American components were found in northern and southern Chile and higher European components were found in central Chile. A negative correlation between African admixture and latitude was observed. On the average, American and European genetic contributions were similar and significantly higher than the African contribution. Weighted mean American, European and African genetic contributions of 44.34% ± 3 9%, 51.85% ± 5.44% and 3.81% ± 0 .45%, were estimated. Fifty two percent of subjects harbor African genes. Individuals with Aymara and Mapuche surnames have an American admixture of 58.64% and 68.33%, respectively. Conclusions: Half of the Chilean population harbors African genes. Participants with Aymara and Mapuche surnames had a higher American genetic contribution than the general Chilean population. These results confirm the usefulness of surnames as a first approximation to determine genetic ancestry. ; Fil: Fuentes, Macarena. Universidad de Tarapacá; Chile ; Fil: Pulgar, Iván.

Background: The first large-scale genome-wide association study of gallbladder cancer (GBC) recently identified and validated three susceptibility variants in the ABCB1 and ABCB4 genes for individuals of Indian descent. We investigated whether these variants were also associated with GBC risk in Chileans, who show the highest incidence of GBC worldwide, and in Europeans with a low GBC incidence. Methods: This population-based study analysed genotype data from retrospective Chilean case-control (255 cases, 2042 controls) and prospective European cohort (108 cases, 181 controls) samples consistently with the original publication. Results: Our results confirmed the reported associations for Chileans with similar risk effects. Particularly strong associations (per-allele odds ratios close to 2) were observed for Chileans with high Native American (=Mapuche) ancestry. No associations were noticed for Europeans, but the statistical power was low. Conclusion: Taking full advantage of genetic and ethnic differences in GBC risk may improve the efficiency of current prevention programs. ; Federal Ministry of Education & Research (BMBF) 01DN15021 European Union (FP7 Research infrastructures) within the initiative "Biobanking and Biomolecular Research Infrastructure -Large Prospective Cohorts" (Collaborative study "Identification of biomarkers for gallbladder cancer risk prediction Towards personali Germany's Excellence Initiative of Heidelberg University within the program "Mobilitaetsmassnahmen im Rahmen internationaler Forschungskooperationen 2015-16" support program "Stiftungen und Preise" of the Ruprecht-Karls-Universitaet Heidelberg German Research Foundation (DFG) LO 2061/1 Biobank of University of Chile
