RESUMO

Background: Cancer genomics, as an interdisciplinary research area within the Global Cancer Research agenda, genomics and precision medicine, its important in research and clinical practice in Latin America. To date, there has been no study investigating evolution of this area in this region. The aim of this study was to evaluate for first time, the historical evolution of cancer genomics research in Latin America. Methods: Bibliometric cross-sectional study of documents on cancer genomics published by Latin American authors until 2023 in Scopus was performed. Statistical and visual analysis was performed with R programming language. Results: A total of 1534 documents were obtained. The first document of cancer genomics research was published in 1997, marking the inception of a 26-year evaluation period that extended until 2023. Among the documents, 74.3% (n = 1140) constituted original articles, followed by 22.7% (n = 349) classified as reviews. International collaboration was observed in 6.5% (n = 100) of the articles. Within the compilation of the ten most prolific authors in this region, 90% of them are from Brazil. This observed pattern extends to affiliations as well, wherein the Universidade de São Paulo emerges as the most active institution (n = 255 documents). This arrangement firmly establishes Brazil's prominence as the preeminent country in the region concerning cancer genomics research, showcasing robust collaboration networks both regionally and intercontinentally. An important transition in the studied hot topics over the last 20 years was identified, from the exploration of the human genome and the characterization of genomic and proteomic cancer profiles (1997-2010) to an in-depth investigation of cancer stem cells and personalized medicine (2011-2023). Among the array of cancer types under study, predominant attention has been directed towards breast, lung, prostate, and leukemia. Conclusion: Over the course of the past 26 years, a favorable and notable evolution has characterized cancer genomics research within Latin America, with Brazil leading the way, which possess a robust network of regional and intercontinental collaboration. Furthermore, the lines of research and hot topics have change in harmony with the region's objectives, strategies, and requisites.

RESUMO

Introduction: People living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) often experience discrimination from both other individuals and the health personnel who care for them. Chile has experienced a marked increase in the number of new HIV cases.Methods: Prospective cross-sectional study. The HIV/AIDS questionnaire for providers and health personnel was obtained from the International Planned Parenthood Federation, initially carrying out a pilot test and evaluating its validity.Results: A total of 784 health professionals answered the questionnaire correctly. Among them, 68.4% (n = 536) were women, and 36.2% (n = 284) were physicians. The study revealed that more than 90% of respondents had a positive attitude towards caring for people living with HIV, and more than 75% did not mind buying food from them or sharing services with them. Furthermore, more than 99% rejected the religiously endorsed labeling of people living with HIV/AIDS as immoral. Additionally, 95.5% (n = 749) mentioned that they did not feel anxious about knowing whether the next patient on their care list was living with HIV, and 76.9% (n = 603) of the respondents felt safe taking blood samples.Conclusions: Chilean health professionals have good knowledge about HIV infection and its mode transmission. Their attitudes towards people living with HIV are also generally positive.
