ABSTRACT The impact of the adequacy empirical therapy on outcome for patients with bloodstream infections (BSI) is key determining whether adequate coverage should be prioritized over other, more conservative approaches. Recent systematic reviews outlined need new studies in field, using improved methodologies. We assessed inadequate treatment mortality BSI present-day context, incorporating recent methodological recommendations. A prospective multicenter cohort including all episodes adult...
Background and aims – Anadenanthera colubrina is a Neotropical native forest tree species with significant ecological importance in Seasonally Dry Tropical Forests. Developing genetic markers for this relevant conservation, breeding, evolutionary studies. Previously available A. consisted of few microsatellites. Next-generation sequencing (NGS) strategies allow simple cost-effective development new SSR loci from low-coverage whole genome shotgun sequencing. The main aim was to develop...
Introduction Despite the availability of new antibiotics such as daptomycin, methicillin-resistant Staphylococcus aureus (MRSA) bacteraemia continues to be associated with high clinical failure rates. Combination therapy has been proposed an alternative improve outcomes but there is a lack studies. The study aims demonstrate that combination daptomycin plus fosfomycin achieves higher success rates in treatment MRSA than alone. Methods and analysis A multicentre open-label, randomised phase...
Carbapenem-resistant Gram-negative bacilli (CR-GNB) are among the most threatening microorganisms worldwide and carbapenem use facilitates their spread. Antimicrobial stewardship programmes (ASPs) can help to optimize of antibiotics. This study evaluates impact a multifaceted educational ASP on epidemiology CR-GNB.We conducted quasi-experimental, time-series in seven hospitals, from January 2014 September 2018. The key intervention was composed interviews promoting appropriate carbapenems....
The proportion of very elderly people in the population is increasing, and infectious diseases this patient group may present with specific characteristics. objective study was to investigate outcome predictors bacteremia among elderly.This a multicenter prospective cohort bloodstream infections (BSI) patients ≥ 80 years old 15 hospitals Spain. variables were 14-day 30-day mortality. Multivariate analysis performed.One hundred twenty episodes included. Mortality 22% (n = 26) on day 14 28%...
The presence of Anadenanthera colubrina var. for the Argentinean flora is confirmed. This variety distinguished by three morphological characters: structure inflorescence, fruit characteristics and venation type folioles, being latter very useful when studying vegetative material. inhabits same areas as cebil. A distribution map, illustrations a key to identify varieties are presented, lectotypes designated Piptadenia macrocarpa Niopa.
Abstract Seasonally Dry Tropical Forests (SDTFs) exhibit a patchy distribution throughout the Neotropics and are considered one of most threatened tropical forests in world. Nonetheless, their conservation has often been neglected comparison to efforts directed towards other biomes. The pattern Anadenanthera colubrina (Vell.) Brenan var. cebil (Griseb) Altschul allows an adequate mapping this biome. main objectives work study historical processes that determined current A. under hypothesis...
We reviewed Bryconamericus species from the Cauca, Magdalena and Ranchería rivers in Colombia using type new specimens. The geographic distribution of B.caucanus was determined. determined morphological variation among analyzed meristic, morphometric osteological characters. shape principal component analysis (PCA), which measurements were previously processed to correct for effect size. number vertebrae differentiated B. caucanus other River (37-39 vs.40-42). arilepis Roman-Valencia et al...
• Premise of the study: Microsatellite primers were developed in native legume tree Anadenanthera colubrina var. cebil to study genetic diversity and structure natural populations Argentina. Methods Results: Nine microsatellite markers identified using a genomic library enriched for tandemly repeated motifs, eight which polymorphic. The polymorphism these was assessed by investigating 20 individuals fragment polymorphism; three 13 alleles observed each locus. Observed expected...
Anadenanthera colubrina var. cebil es una especie nativa sudamericana que caracteriza a los Bosques Secos Estacionales Neotropicales, cuales se presentan en parches disyuntos dispersosa lo largo del Neotrópico. La influencia de las fluctuaciones climáticas pasado sobre la distribución actual dichos bosques ha merecido diferentes interpretaciones, debido postula lascondiciones tropicales no fueron estables durante el Cenozoico. El objetivo este estudio identificar rastros eventos...
Abstract Anadenanthera colubrina var cebil is a tree species native to the Upper Parana Atlantic Forest where human activities have severely impacted causing deep fragmentation. Microsatellites are not available in this species. Therefore, first objective of study was generate chloroplast simple sequence repeats (cpSSR) by cross-species transfer. Understanding evolutionary dynamics subdivided populations an important matter. In way, approach characterization haplotypic diversity within and...
