Facing migration under adverse conditions: challenges and resilience in the Colombo-Venezuelan border area.

Background: Internal displacement and cross-country migration are an increasing global phenomenon drawing the attention of politicians and the public. Causes and effects on the migrants and receptor populations are varied and often shaped by immigration laws and how migrants and refugees are being dealt with by local conditions, policy frameworks and by the host population (receptors). The massive influx of Venezuelan migrants into Colombia for more than a decade has characteristics which warrant a systematic analysis to identify contextual and individual factors favouring and hindering the well-being of migrants and their new Colombian neighbours of the receptor population.

Determination of prion proteins in the diagnosis of Creutzfeldt-Jakob disease using RT-QuIC: A case report from northeastern Colombia.

Creutzfeldt-Jakob disease is a rare neurodegenerative disease caused by prions. We present the case of a woman in the seventh decade of life with rapidly progressive dementia and myoclonus. Her brain magnetic resonance imaging revealed lesions in the basal nuclei, and the electroencephalogram showed periodic bilateral epileptiform discharges.

Global, regional, and national estimates of tuberculosis incidence and case detection among incarcerated individuals from 2000 to 2019: a systematic analysis.

Background: People who are incarcerated are at high risk of developing tuberculosis. We aimed to estimate the annual global, regional, and national incidence of tuberculosis among incarcerated populations from 2000 to 2019.

Methods: We collected and aggregated data for tuberculosis incidence and prevalence estimates among incarcerated individuals in published and unpublished literature, annual tuberculosis notifications among incarcerated individuals at the country level, and the annual number of incarcerated individuals at the country level.

Factors associated with excessive daytime sleepiness in informal drivers of buses on a high-altitude road.

Objective: To determine the factors associated with excessive daytime sleepiness (EDS) in informal interprovincial transport drivers of the Lima-Huancayo central highway (Peru) from January to March 2018.

Methods: Cross-sectional study. The drivers were weighed and measured, then individual, sociodemographic, and occupational data were obtained which were recorded in a data collection form, then the Epworth Sleepiness Scale (ESS) was applied to the drivers.

Chromosome rearrangements shape the diversification of secondary metabolism in the cyclosporin producing fungus Tolypocladium inflatum.

Background: Genes involved in production of secondary metabolites (SMs) in fungi are exceptionally diverse. Even strains of the same species may exhibit differences in metabolite production, a finding that has important implications for drug discovery. Unlike in other eukaryotes, genes producing SMs are often clustered and co-expressed in fungal genomes, but the genetic mechanisms involved in the creation and maintenance of these secondary metabolite biosynthetic gene clusters (SMBGCs) remains poorly understood.

Hypothermia indices among severely injured trauma patients undergoing urgent surgery: A single-centred retrospective quality review and analysis.

Background: Hypothermia (<36°C) exacerbates trauma-induced coagulopathy and worsens morbidity and mortality among severely injured trauma patients; there is a paucity of published data describing how well trauma centres adhere to standards regarding measurement of temperature, and best practices for preventing and treating hypothermia.

Methods: We completed a retrospective quality audit of all severely injured trauma patients (Injury Severity Score (ISS≥20)) who had urgent surgery at Sunnybrook Health Sciences Centre (SHSC) between 2010 and 2014. Information regarding temperature monitoring was evaluated over the course of the initial resuscitation and admission.

Global population structure and adaptive evolution of aflatoxin-producing fungi.

Aflatoxins produced by several species in section are a significant problem in agriculture and a continuous threat to human health. To provide insights into the biology and global population structure of species in section , a total of 1,304 isolates were sampled across six species ( and ) from single fields in major peanut-growing regions in Georgia (USA), Australia, Argentina, India, and Benin (Africa). We inferred maximum-likelihood phylogenies for six loci, both combined and separately, including two aflatoxin cluster regions ( and ) and four noncluster regions ( and ), to examine population structure and history.

Enhanced diversity and aflatoxigenicity in interspecific hybrids of Aspergillus flavus and Aspergillus parasiticus.

Aspergillus flavus and A. parasiticus are the two most important aflatoxin-producing fungi responsible for the contamination of agricultural commodities worldwide. Both species are heterothallic and undergo sexual reproduction in laboratory crosses.

Analysis of the Candida albicans Phosphoproteome.

Candida albicans is an important human fungal pathogen in both immunocompetent and immunocompromised individuals. C. albicans regulation has been studied in many contexts, including morphological transitions, mating competence, biofilm formation, stress resistance, and cell wall synthesis.

Sexual recombination in Aspergillus tubingensis.

Aspergillus tubingensis from section Nigri (black Aspergilli) is closely related to A. niger and is used extensively in the industrial production of enzymes and organic acids. We recently discovered sexual reproduction in A.

Sexual reproduction in Aspergillus flavus sclerotia naturally produced in corn.

Aspergillus flavus is the major producer of carcinogenic aflatoxins worldwide in crops. Populations of A. flavus are characterized by high genetic variation and the source of this variation is likely sexual reproduction.

Sexual reproduction in Aspergillus tubingensis from section Nigri.

A sclerotium-forming member of Aspergillus section Nigri was sampled from a population in a single field in North Carolina, USA, and identified as A. tubingensis based on genealogical concordance analysis. Aspergillus tubingensis was shown to be heterothallic, with individual strains containing either a MAT1-1 or MAT1-2 mating-type gene.

Effect of sexual recombination on population diversity in aflatoxin production by Aspergillus flavus and evidence for cryptic heterokaryosis.

Aspergillus flavus is the major producer of carcinogenic aflatoxins (AFs) in crops worldwide. Natural populations of A. flavus show tremendous variation in AF production, some of which can be attributed to environmental conditions, differential regulation of the AF biosynthetic pathway and deletions or loss-of-function mutations in the AF gene cluster.

Transmission Efficiency of Potato virus Y strains PVY and PVY by Five Aphid Species.

Potato virus Y (PVY) is a reemerging problem in potato production in North America. Although the "ordinary" strain, PVY, is still the dominant isolate in U.S.

Nonalcoholic fatty liver disease is associated with insulin resistance in a young Hispanic population.

Objective: To investigate whether nonalcoholic fatty liver disease (NAFLD) is associated with insulin resistance (IR) in a young Hispanic population.

Methods: A cross-sectional study was performed in Bogotá, Colombia, during 2006 in 263 males from the Colombian Air Force (age range 29-54 years). Anthropometric measurements and biochemical determinations (glycemia, lipid profile, insulin, and HOMA-IR) were obtained in order to determine the presence of metabolic syndrome (MS) criteria and insulin resistance in this population.
