“…In addition, a very high proportion (45%) of subjects infected with the lineage B CAR-SA-I in French Guiana where from Guyana. At last, the intense human mobility across the Roraima border with Guyana ( Pereira, 2006 ; Corbin, 2007 ) coincides with a high prevalence of the lineage B CAR-SA-I in that Northern Brazilian state ( Divino et al, 2016 ). These epidemiological data therefore suggest that lineage B CAR-SA-I arose in Guyana.…”

The HIV-1 Subtype B Epidemic in French Guiana and Suriname Is Driven by Ongoing Transmissions of Pandemic and Non-pandemic Lineages

et al. 2018

The HIV-1 subtype B epidemic in French Guiana and Suriname is characterized by the co-circulation of the globally disseminated “BPANDEMIC” lineage and of non-pandemic subtype B lineages of Caribbean origin (BCAR). To reconstruct the spatiotemporal pattern of spread of those viral lineages circulating in these two countries, a total of 361 HIV-1 subtype B pol sequences recovered from treatment-naive adult patients from French Guiana and Suriname between 2006 and 2012 were combined with BPANDEMIC and BCAR reference sequences. Major Guianese/Surinamese BPANDEMIC and BCAR lineages were identified by Maximum Likelihood phylogenetic analysis and the spatiotemporal and demographic parameters estimated using a Bayesian coalescent-based method. We detected four BCAR and three BPANDEMIC transmission chains of large size that together comprise most pandemic and non-pandemic subtype B sequences from French Guiana (≥52%) and Suriname (≥70%) here analyzed. These major lineages were probably introduced into French Guiana and Suriname from the Caribbean (BCAR) and North/South America (BPANDEMIC) between the middle 1970s and the late 1980s and spread among populations from both countries with roughly comparable demographic growth rates. We detected a significant trend for higher viral loads and higher proportion of homosexual/bisexual men among subjects infected with BPANDEMIC relative to BCAR strains in French Guiana. These results show that the HIV subtype B epidemic in French Guiana and Suriname has been driven by multiple active BCAR and BPANDEMIC transmission chains that arose since the middle 1970s onward and operate in both countries simultaneously. Although no significant differences in the epidemic potential of major BCAR and BPANDEMIC lineages were observed, relevant associations between the infecting subtype B lineage and epidemiological and clinical characteristics were detected in French Guiana.

“…This population growth was fueled by the creation of incentives to immigration and the inauguration of important highways that gave access to large areas of the state, including some at the border with Guyana [ 41 , 42 ]. Many Brazilian migrants initially attracted by the rise of legal/illegal mining activities in Roraima later migrated to Guyana, and Brazil is (together with Suriname and Venezuela) one of the major migrants exporting countries to Guyana [ 33 , 37 , 38 ]. The economic crisis in Guyana also produced an increasing migration flux of Guyanese people to Roraima since the 1960s onwards, particularly to the neighboring district of Bonfim and the state capital Boa Vista [ 33 , 37 , 38 ].…”

These drastic changes in the demographic structure and population mobility may have fueled the introduction and dissemination of Guyanese B CAR strains into Roraima.…”

High Prevalence and Onward Transmission of Non-Pandemic HIV-1 Subtype B Clades in Northern and Northeastern Brazilian Regions

et al. 2016

The Human immunodeficiency virus type-1 (HIV-1) epidemic in Brazil is mainly driven by the subtype B pandemic lineage (BPANDEMIC), while Caribbean non-pandemic subtype B clades (BCAR) seem to account for a very low fraction of HIV-infections in this country. The molecular characteristics of the HIV-1 subtype B strains disseminated in the Northern and Northeastern Brazilian regions, however, have not been explored so far. In this study, we estimate the prevalence of the HIV-1 BPANDEMIC and BCAR clades across different Brazilian regions and we reconstruct the spatiotemporal dynamics of dissemination of the major Brazilian BCAR clades. A total of 2,682 HIV-1 subtype B pol sequences collected from 21 different Brazilian states from the five country regions between 1998 and 2013 were analyzed. Maximum Likelihood phylogenetic analyses revealed that the BCAR strains reached 16 out 21 Brazilian states here analyzed. The BCAR clades comprise a low fraction (<10%) of subtype B infections in most Brazilian states analyzed, with exception of Roraima (41%), Amazonas (14%) and Maranhão (14%). Bayesian phylogeographic analyses indicate that BCAR strains originally from the Hispaniola and Trinidad and Tobago were introduced at multiple times into different states from all Brazilian regions and a few of those strains, probably introduced into Roraima, Maranhão and São Paulo between the late 1970s and the early 1980s, established secondary outbreaks in the Brazilian population. These results support that the HIV-1 subtype B epidemics in some Brazilian states from the Northern and Northeastern regions display a unique molecular pattern characterized by the high prevalence of BCAR lineages, which probably reflects a strong epidemiological link with the HIV-1 epidemics in the Caribbean region.

“…Para alguns autores, existe um imaginário social que caracteriza a fronteira como lugar do esvaziamento tanto físico quanto político, sendo o substrato dessa vivência o que importa. Ou seja, não é a demarcação geográfica que põe sentido às suas vidas, e sim os significados das relações sociais e culturais que são estabelecidas (FARAGE, 1991;SANTILLI, 2001;PEREIRA, 2006).…”

Transitando entre dois estados, vou enganando-me e "passando a perna" no Estado burguês ResumoEste artigo pretende dialogar com as ideias do filósofo Antonio Gramsci sobre educação. A ideia é discutir, com base numa realidade concreta -a região de fronteira -, elementos da contra-hegemonia presente nas relações de ensino-aprendizagem. Para tanto, este texto apresenta as experiências de duas professoras, uma como profissional da educação básica da rede estadual de ensino do Tocantins, em município limítrofe com o estado de Goiás, e a outra como professora do ensino superior, que, ao realizar um trabalho de pesquisa de campo, intuiu o quão significativo seria um recorte investigativo sobre os aspectos da educação escolar naquela fronteira interna do Brasil. Trata-se de fronteira entre municípios de dois estados: Tocantins e Goiás. A metodologia faz uso de memória, análise de documentos e entrevistas dos pioneiros e professores mais velhos, ainda moradores daquela região. A narrativa se faz na primeira pessoa do plural para assumir um local de inserção naquele contexto e de coautoria. Trata-se, portanto, de um artigo que dialoga com autores das áreas de educação, antropologia, sociologia, história e geografia.Palavras-chave: Educação. Estado. Fronteira. Goiás. Tocantins. AbstractThis article aims to dialogue with the philosopher Antonio Gramsci's ideas on education. The idea is to discuss the basis of a concrete reality -the border region -elements of counter-hegemony present within teaching--learning relationships. Therefore, this work reflects the experiences of two teachers, one a professional primary educator from the state of Tocantin's school system, a neighboring municipality with the state of Goiás, and the other a higher education teacher that undertook research field work there, intuited significant as it would be an investigative recut on aspects of education within an internal border of Brazil. This is the border between the municipalities of two states: Tocantins and Goiás. The methodology makes use of memory, document analysis, and interviews of the older pioneers and teachers, and even the inhabitants of the region. The narrative is in the first person plural to assume an insertion place in that context and with co-authorship. It is, therefore, an article that will dialogue with authors of education, anthropology, sociology, history and geography.
