ABSTRACT
Se presenta el índice referativo de la Revista Cubana de Informática Médica correspondiente a los años 2019-2021. Se incluyen índices auxiliares de autor, instituciones, materias y direcciones electrónicas para facilitar el contacto con los autores y la consulta de la producción científica publicada por la revista. Se utilizó CDS/ISIS para Windows (versión 1.5.3) de la UNESCO, a partir de la cual se generaron los índices auxiliares de autor, instituciones y materias. Con ello se pretende que los profesionales, técnicos, directivos y estudiantes vinculados a esta importante disciplina en el país y el mundo, dispongan de una fuente de información para realizar investigaciones bibliográficas en este campo tan importante para la salud pública cubana(AU)
The reference index of the Cuban Journal of Medical Informatics corresponding to the years 2019-2021 is presented. Auxiliary indexes of authors, institutions, subjects and electronic addresses are included to facilitate contact with the authors and the consultation of the scientific production published by the journal. UNESCO's CDS/ISIS for Windows (version 1.5.3) was used, from which auxiliary author, institution and subject indexes were generated. With this, it is intended that professionals, technicians, managers and students linked to this important discipline in the country and the world, have a source of information to carry out bibliographic research in this field so important for Cuban public health(AU)

BACKGROUND Panstrongylus rufotuberculatus (Hemiptera-Reduviidae) is a triatomine species with a wide geographic distribution and a broad phenotypic variability. In some countries, this species is found infesting and colonising domiciliary ecotopes representing an epidemiological risk factor as a vector of Trypanosoma cruzi, etiological agent of Chagas disease. In spite of this, little is known about P. rufotuberculatus genetic diversity. METHODS Cytogenetic studies and DNA sequence analyses of one nuclear (ITS-2) and two mitochondrial DNA sequences (cyt b and coI) were carried out in P. rufotuberculatus individuals collected in Bolivia, Colombia, Ecuador and Mexico. Moreover, a geometric morphometrics study was applied to Bolivian, Colombian, Ecuadorian and French Guiana samples. OBJECTIVES To explore the genetic and phenetic diversity of P. rufotuberculatus from different countries, combining chromosomal studies, DNA sequence analyses and geometric morphometric comparisons. FINDINGS We found two chromosomal groups differentiated by the number of X chromosomes and the chromosomal position of the ribosomal DNA clusters. In concordance, two main morphometric profiles were detected, clearly separating the Bolivian sample from the other ones. Phylogenetic DNA analyses showed that both chromosomal groups were closely related to each other and clearly separated from the remaining Panstrongylus species. High nucleotide divergence of cyt b and coI fragments were observed among P. rufotuberculatus samples from Bolivia, Colombia, Ecuador and Mexico (Kimura 2-parameter distances higher than 9%). MAIN CONCLUSIONS Chromosomal and molecular analyses supported that the two chromosomal groups could represent different closely related species. We propose that Bolivian individuals constitute a new Panstrongylus species, being necessary a detailed morphological study for its formal description. The clear morphometric discrimination based on the wing venation pattern suggests such morphological description might be conclusive.
ABSTRACT
Bolivia is a high-endemic country for Chagas disease, for which the principal vector is Triatoma infestans (Triatominae). This is a mainly domestic species that is also found in the wild environment. Recently, an increasing number of studies have shown the importance of Triatominae resistance to insecticides, especially in Bolivia. Data regarding the susceptibility/resistance of wild and domestic populations of T. infestans to deltamethrin are presented. For the first time, domestic populations of the department of Santa Cruz were tested, showing low resistance. Although most of the wild populations were found to be susceptible to deltamethrin, three populations from three departments showed a mortality rate of less than 100%. This result is emphasised here.
