Obtención de algunos parámetros de referencia del suelo y del mucílago de aloe vera cultivado en el corregimiento de Combia Risaralda y en el municipio de Montenegro Quindío

Se llevó a cabo un estudio comparativo entre cultivos de Aloe vera del departamento Risaralda y del departamento del Quindío. Se realizó la determinación de nutrientes en el suelo del cultivo y el análisis Bromatológico del Mucílago. Las muestras fueron tomadas de cuatro fincas pertenecientes al corregimiento de Combia, municipio de Pereira, Risaralda, y de la hacienda Nápoles en el municipio de Montenegro departamento del Quindío. Según los resultados de los análisis existen algunas diferencias entre los cultivos de las dos regiones sin embargo las dos son aptas para el cultivo de Aloe vera.A comparative study was carried out between Aloe vera growth from Risaralda Department and Quindío department.

Research, Innovation and Extension to the service to society, in the framework of the Sixth Conference on Social Appropriation of Knowledge (SAK)

Annually, the Technological University of Pereira has been carrying out some events in the line of Social Appropriation of Knowledge. This has been done through the research, innovation, and extension Vice Rectory, moreover, these sessions are framed within the institutional objective: “Define and direct the guidelines for the institutional research that strengthen the research groups and the Seedbeds, through the formation of researchers, the development of science, technology, and innovation projects or programs, as well as the generation of networks and strategic partnerships that contribute to the creation and appropriation of knowledge for the society”. Therefore, the 6th Social Appropriation of Knowledge event took place under the title of “The research, Innovation, and Extension at the service of society” which was constituted as an academic and institutional opportunity where the results of the research projects from the last 5 years were published. The results of this event revealed, once again, the high academic level in investigation development at the university. There were 11 articles divided into 6 fields: Health, Engineering, Technology, Education, Industrial Technology, and Art, in which the results obtained by the research projects from the investigation groups were shown, promoting a knowledge exchange from their authors whose intellectual formation is diverse. With this publication, as part of a permanent effort to socialize the knowledge, the university promotes the circulation of its professors, students, and general community voices, having in mind that knowledge must be transferred through different channels, strengthening the academy and society in general, according to the institutional mission that invites us to incentivize a research culture in the university community.Presentation........................................................................................................... 5 Chapter 1.

Prevalence and Clinical Outcomes of Poor Immune Response Despite Virologically Suppressive Antiretroviral Therapy Among Children and Adolescents With Human Immunodeficiency Virus in Europe and Thailand: Cohort Study

International audienceIn human immunodeficiency virus (HIV)-positive adults, low CD4 cell counts despite fully suppressed HIV-1 RNA on antiretroviral therapy (ART) have been associated with increased risk of morbidity and mortality. We assessed the prevalence and outcomes of poor immune response (PIR) in children receiving suppressive ART

Prevalence and Clinical Outcomes of Poor Immune Response Despite Virologically Suppressive Antiretroviral Therapy Among Children and Adolescents With Human Immunodeficiency Virus in Europe and Thailand: Cohort Study

BACKGROUND: In human immunodeficiency virus (HIV)-positive adults, low CD4 cell counts despite fully suppressed HIV-1 RNA on antiretroviral therapy (ART) have been associated with increased risk of morbidity and mortality. We assessed the prevalence and outcomes of poor immune response (PIR) in children receiving suppressive ART. METHODS: Sixteen cohorts from the European Pregnancy and Paediatric HIV Cohort Collaboration (EPPICC) contributed data. Children <18 years at ART initiation, with sustained viral suppression (VS) (≤400 copies/mL) for ≥1 year were included. The prevalence of PIR (defined as World Health Organization advanced/severe immunosuppression for age) at 1 year of VS was described. Factors associated with PIR were assessed using logistic regression. Rates of acquired immunodeficiency syndrome (AIDS) or death on suppressive ART were calculated by PIR status. RESULTS: Of 2318 children included, median age was 6.4 years and 68% had advanced/severe immunosuppression at ART initiation. At 1 year of VS, 12% had PIR. In multivariable analysis, PIR was associated with older age and worse immunological stage at ART start, hepatitis B coinfection, and residing in Thailand (all P ≤ .03). Rates of AIDS/death (95% confidence interval) per 100 000 person-years were 1052 (547, 2022) among PIR versus 261 (166, 409) among immune responders; rate ratio of 4.04 (1.83, 8.92; P < .001). CONCLUSIONS: One in eight children in our cohort experienced PIR despite sustained VS. While the overall rate of AIDS/death was low, children with PIR had a 4-fold increase in risk of event as compared with immune responders
