Classic test and generalizability theories are both useful for cross-cultural adaptation of an allergic rhinitis health-related quality of life questionnaire.

Background: An instrument to assess Allergic Rhinitis (AR) Health-Related Quality of Life (HRQL) in adult patients was developed in Spain. No validated instrument is currently cross-culturally adapted for use in daily practice to assess HRQL in AR patients in Colombia.

Purpose: The aim of this study was to evaluate the measurement performance of an AR-HRQL specific questionnaire, ESPRINT-15 (Cuestionario ESPañol de Calidad de Vida en RINiTis), in Colombian adult patients with AR using the Classic Test Theory (CTT) and the Generalizability theory (G-theory) frameworks.

Mental health, interpersonal trust and subjective well-being in a high violence context.

This paper assesses whether two factors of wellbeing, social capital (interpersonal trust and social networks) and subjective well-being are associated with frequent mental distress and if there are any mediating effects by gender in a city of high urban violence. This paper relies on data that comes from a sample of over 1300 people representative by gender, race/ethnicity, and socioeconomic breakdown of the city of Cali in Colombia, which was collected in 2017 through face-to-face surveys. Our study uses logistic regression with fixed-effects at the district level to control for unobserved time-invariant factors.

Debt portfolios of street vendors: Survey data from Colombia.

This paper presents data about the indebtedness of the poor, in particular, street vendors from Cali, Colombia. In Latin America, as in many other developing regions, the poor have no access to credit from regulated institutions. Bank fees, transaction costs and lack of durable assets to back up indebtedness, exclude the poor form the banking system and their only resort for credit are moneylenders who charge predatory interest rates.

Establishment of Two Dimensional (2D) and Three-Dimensional (3D) Melanoma Primary Cultures as a Tool for In Vitro Drug Resistance Studies.

Characteristics of melanoma cells have been deciphered by studies carried out in two dimensional cell cultures growing as adherent monolayers on the bottom of plastic flasks. Melanoma cells can be cultured with a considerable degree of success, and, depending on the further use of the cells obtained in the culture, methodologies have to be adjusted to obtain reliable results. Although there are many melanoma continuous cell lines, in vitro 2D and 3D melanoma primary cell culture may be a more useful model to investigate interactions between cancer cells and immune system, as well as the effect of cytotoxic treatments and personalized medicine in environments more similar to the physiological conditions.

Street vending and informal economy: Survey data from Cali, Colombia.

This data brief describes data collected in Cali, Colombia about the economic dynamic and socioeconomic conditions of street vendors in the city. The study was conducted between 2014 and 2016 in two populated sites in terms of formal and informal commerce in the city. We present the methodology followed in the study, location of street vending sites and type of data collected to approximate to the economic dimension of street vending.

[Evaluation of the genotoxic effect of malaria in a cohort of patients in Medellín and Quibdó].

Introduction: During malaria infection, both parasite and host are under the effects of oxidative stress due to the increased production of reactive oxygen species, which can induce DNA damage by its genotoxic effects.

Objective: To evaluate genotoxic effects in human lymphocytes in a cohort of patients with malaria from Medellin and Quibdó.

Methods: We performed an observational cross sectional study in 100 individuals with malaria and 100 healthy controls.
