Fatores de risco associados a alterações renais em pacientes infectados por HIV-1

INTRODUÇÃO: A doença renal é uma das principais comorbidades envolvendo pacientes infectados com o HIV, em razão da melhora da sobrevida proporcionada pela terapêutica antirretroviral. O objetivo deste estudo foi detectar fatores de risco, possivelmente correlacionados com função renal alterada, em pacientes infectados pelo HIV. MÉTODOS: Estudo transversal foi realizado em 254 pacientes infectados pelo HIV, atendidos em ambulatório na Santa Casa de Vitória. Eles foram entrevistados e submetidos a coletas de amostras de sangue para contagem de células CD4, quantificação de carga viral do HIV-1, dosagens de glicose, lipídeos e creatinina. A proteinúria foi avaliada em amostra de primeira urina da manhã. A filtração glomerular foi estimada com as fórmulas de modified diet in renal disease (MDRD) simplificada e Cockcroft-Gault. RESULTADOS: Cento e três (40,6%) pacientes tinham alguma anormalidade no exame de urina, sendo proteinúria o achado mais comum (46; 18,1% pacientes). Vinte e cinco (9,8%) pacientes tinham filtração glomerular estimada inferior a 60ml/min/1.73m² de acordo com MDRD. A análise de regressão logística multivariada mostrou que baixa filtração glomerular foi positivamente correlacionada com raça negra [OR 9,6 (IC95% 1,28-23,80)], hipertensão arterial sistêmica [OR 3,3 (IC95% 1,28-23,81)], idade acima de 51 anos [OR 3,3 (IC95%1,11-9,90)], proteinúria [OR 5,2 {IC95% 1,67-16,25}]; hematúria [OR 3,2 (1,12-9,29)] e negativamente com pacientes em uso de zidovudina [OR 0,2 (0,04-0,78)]. CONCLUSÕES: Os fatores de risco tradicionais para doença renal como raça negra, hipertensão arterial e idade avançada foram correlacionados com menor filtração glomerular estimada em nossos pacientes

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set.

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used.
