Association between peripheral venous catheter failure and care complexity factors in emergency department: a cross-sectional study.

Objective: The objective was to determine the prevalence of peripheral venous catheter (PVC) failure and its association with care complexity individual factors (CCIFs) in emergency department (ED) patients.

Design: A cross-sectional, descriptive-correlational study was performed.

Methods: All patients with a PVC inserted in the ED of a tertiary hospital were included.

Care complexity factors associated with revisits to an emergency department.

Objectives: To analyze the prevalence of care complexity factors (CCFs) in patients coming to an emergency department (ED) and to analyze their relation to 30-day ED revisits.

Material And Methods: Observational, correlational, and cross-sectional study. Consecutive patients seeking care from a tertiarylevel hospital ED were included over a period of 6 months.

Molecular and serological rapid tests as markers of Trypanosoma cruzi infection in dogs in Costa Rica.

Introduction: Chagas disease is a zoonotic disease caused by Trypanosoma cruzi and dogs are one of the main domestic reservoirs.

Materials And Methods: One molecular (OligoC-TesT, Coris Bioconcept) and one serological (T. cruzi-Detect, Inbios) rapid tests were evaluated as infection markers for T.

In vitro activity of thienyl-2-nitropropene compounds against Trypanosoma cruzi.

The in vitro activity of four 2-nitropropene derivatives, 1-(3-benzothienyl)-2-nitropropene (N1), 1-(3-thienyl)-2-nitropropene (N2), 1-(5-bromo-2-thienyl)-2-nitropropene (N3) and 1-(4-bromo-2-thienyl)-2-nitropropene (N4), were tested against cultures of the parasite Trypanosoma cruzi. Cytotoxicity studies were performed using Vero cells. The blood trypomastigotes, amastigotes and epimastigotes showed differential degrees of sensitivity towards the four tested compounds; the highest activity against the epimastigotes and blood tripomastigotes was exhibited by N1, followed by N3, N4 and finally N2.

Trypanosoma rangeli genotypes association with Rhodnius prolixus and R. pallescens allopatric distribution in Central America.

Previous kDNA polymorphism-based reports have revealed the existence of two Trypanosoma rangeli genotypes (KP1+ and KP1-): SL and SSU rRNA gene polymorphism-based studies have revealed that five genotypes (A-E) are distributed throughout different Latin-American countries. Some evidence has shown that the genotypes' biogeographical distribution is associated with sympatric Rhodnius species. 12 T.

Ecological control of Triatoma dimidiata (Latreille, 1811): five years after a Costa Rican pilot project.

An ecological pilot project for the control of Triatoma dimidiata allowed a new evaluation four and five years after environmental modifications in the peridomestic areas of 20 households. It was verified that the two groups of houses, 10 case-houses and 10 control-houses, were free of insects after those periods of time. In the first group, the owners started a chicken coop in the backyard and a colony of bugs was found there without infesting the house.
