[Phylogenetic analysis of South American sequences of the nonstructural protein-1 (ns1) of dengue serotype 2 associated with severe clinical bleeding].

Objective The objective of this in silico study was to compare nucleotide and amino acids DENV-2-NS1 sequences isolated from febrile patients, with and without disease severity, from different South American countries. Matherials and Methods A bayesian MCMC phylogenetic analysis was carried out using 28 complete sequences of the gene NS1 of the DENV-2 serotype (1 056 bp), using MrBayes v.3.

[Differences and similarities in approach of integrated strategy for dengue prevention and control between Colombia and Peru].

We analyzed and compared two Integrated Management Strategies for Dengue Prevention and Control (IMS-dengue Colombia and IMS-dengue Peru), through a narrative review of available literature, in order to identify common and dissimilar patterns in two Andean countries with epidemiological differences in the context of dengue disease. We were able to identify differences related to: formal assessment of problem, formation of groups of actors, and quantitative information provided by performance indicators. These limitations identified in IMS-dengue Colombia 2006-2010 were overcome in a new version of the strategy (IMS-dengue Colombia 2012-2021).

[Cardiovascular risk factors among 7-and 14-year old schoolchildren in Cartagena, Colombia, 2009].

Objective: Identifying family history, dyslipidaemia, hyperglycaemia, low physical activity and being overweight or suffering from obesity as cardiovascular risk factors in children aged 7 to 14 years in Cartagena, 2009.

Materials And Methods: A descriptive study of 173 children from Cartagena, Colombia, was designed. Biochemical serum parameters were determined by spectrophotometric methods.

[Antimicrobial resistance pattern for gram-negative uropathogens isolated from hospitalised patients and outpatients in Cartagena, 2005-2008].

Objective: Determining the microbial aetiology spectrum and antibiotic resistance pattern of uropathogens causing urinary tract infections in hospitalised patients and outpatients.

Methods: A descriptive study was carried out between February 2005 and November 2008 at the San Buenaventura University's Clinical Laboratory in Cartagena. Antibiotic sensitivity was determined by the Kirby Bauer method.

[Methicillin-resistant Staphylococcus aureus in children attending school in Cartagena, Colombia].

Objective: Determining nasal carriers of methicillin-resistant Staphylococcus aureus (MRSA) and associated risk factors for nasal colonisation in a school-aged population in the seaside city of Cartagena, Colombia.

Methods: A cross-sectional, analytical study was carried out on 100 healthy schoolchildren to determine MRSA nasal carriage and its association with risk factors. Bacteria were identified using conventional methods.
