Prácticas de cultura universitaria. El caso del ciclo de formación ciudadana de la Corporación Universitaria Minuto de Dios Sede Bello

The article analyzes the Centro de Educación para el Desarrollo (CED or Center for Education towards Development, in English) of the Corporación Universitaria Minuto de Dios (Uniminuto) wagers about the  citizen formation cycle. The paper assesses the efforts taken on by that academic unit to carry out the individual and social development of its students from the aperture of spaces for citizen, ethic-political, civic, coexistence and consolidation of democracy reflections. The analysis begins with the citizen formation cycle creation and background consolidation, the conceptual bases that moderated the citizenship topic in the CED, the citizenship conference principles, the thematic lines that took part of that strategy, the strategic alliances between the planned jobs of the CED to enhance the citizenship culture activities, and the cycle’s perspectives and orientations. The study is supported by primary information consulted from the CED’s archive management of Uniminuto’s campus in Bello, and complementary bibliography of institutional and pedagogic character in the Education for Development (EfD) perspective.El artículo analiza las apuestas que el Centro de Educación para el Desarrollo (CED) de la Corporación Universitaria Minuto de Dios (Uniminuto), sede Bello, realiza en materia del ciclo de formación ciudadana.

Kangaroo mother care had a protective effect on the volume of brain structures in young adults born preterm

Q1Q1Jóvenes adultosAim: The protective effects of Kangaroo mother care (KMC) on the neurodevelop-ment of preterm infants are well established, but we do not know whether the ben-efits persist beyond infancy. Our aim was to determine whether providing KMC in infancy affected brain volumes in young adulthood. Method: Standardised cognitive, memory and motor skills tests were used to determine the brain volumes of 20-year-old adults who had formed part of a randomised controlled trial of KMC versus incubator care. Multivariate analysis of brain volumes was conducted according to KMC exposure. Results: The study comprised 178 adults born preterm: 97 had received KMC and 81 were incubator care controls. Bivariate analysis showed larger volumes of total grey matter, basal nuclei and cerebellum in those who had received KMC, and the white matter was better organised. This means that the volumes of the main brain structures associated with intelligence, attention, memory and coordination were larger in the KMC group. Multivariate lineal regression analysis demonstrated the direct rela-tionship between brain volumes and duration of KMC, after controlling for potential confounders. Conclusion: Our findings suggest that the neuroprotective effects of KMC for pre-term infants persisted beyond childhood and improved their lifetime functionality and quality of life.https://orcid.org/0000-0001-6697-5837https://orcid.org/0000-0002-1923-3934https://orcid.org/0000-0001-5464-2701Revista Internacional - IndexadaA1N

Introducción: La implantación de catéteres translumbares es un tipo de abordaje venoso que constituye una de las últimas opciones en pacientes sin disponibilidad de accesos venosos centrales convencionales. Objetivos: Revisar la literatura, describir la técnica y comunicar la experiencia de seis años en la realización de este procedimiento. Métodos: Se realizó una búsqueda de la literatura disponible sobre la implantación de catéteres translumbares en MedLine, Ovid y Liliacs; asimismo, se obtuvo una base de datos sobre los pacientes en quienes se implantó un catéter translumbar en el Hospital Universitario San Ignacio en el periodo entre 2008 y 2013. Finalmente, se ejecutó un estudio retrospectivo descriptivo. Resultados: Se realizaron 98 procedimientos en 66 pacientes (41 hombres y 25 mujeres). Se observó la incidencia de complicaciones hasta 72 horas posprocedimiento y se identificaron solo tres complicaciones (4,6 %) Conclusiones: El implante de catéteres translumbares constituye una alternativa eficaz y segura en pacientes que necesitan hemodiálisis y han agotado otros accesos venosos convencionales. Los resultados se hallan dentro de los indicadores publicados en la literatura.Artículo original4062-4066Introduction: In recent years the Hospital Universitario San Ignacio has become a local and national reference center for translumbar catheter placement. This procedure is one of the last options to achieve effective central venous access in patients without other possible alternatives. Objectives: To review the literature, describe the technique and report the experience of six years in the making of this procedure. Methods: Search of the available literature about translumbar catheter placement was performed in MEDLINE, OVID and LILIACS. Additionally, it was obtained a database on patients with translumbar catheter placement at Hospital Universitario San Ignacio in the 2008-2013 period. Finally a retrospective study was made. Results: 98 Procedures were performed in 66 patients (41 men and 25 women). The incidence of complications up to 72 hours post-procedure was observed, identifying only 3 complications (4.6%) Conclusions: Translumbar catheter placement is an effective and safe alternative in patients requiring hemodialysis and have exhausted other conventional venous accesses. Our results are according to those reported in the available literature

Association between periodontal disease and endothelial dysfunction in smoking patients

Q329-35Over the past two decades, there has been increasing interest in the impact of oral health on cardiovascular disease, particularly regarding the effects of chronic infections such as periodontitis on the endothelium. The aim of this study was to evaluate in healthy smokers whether there are any significant differences in the frequency of endothelial dysfunction between subjects with chronic moderate to severe periodontal disease and periodontally healthy subjects. An observational cross-sectional study was conducted. The target population was adults older than 40 years of age. Blood tests were performed to determine values of CBC, glycaemia, total cholesterol, HDL-C, and LDLC. Periodontal examinations and probing were conducted with a Florida Probe®, and standardized procedures were used to measure flow-mediated dilation. Out of 150 subjects [69 male (46%) and 81 female (54%)], 75 (50%) had chronic periodontitis. The mean value for baseline flow-mediated dilation was 4.04% and the mean value for final flow-mediated dilation was 4.66%, with a 0.62% mean difference showing a statistically significant increase (p<0.001).This study found no significant difference in the flow-mediated dilation values between periodontally healthy subjects and those with periodontitis, in contrast to the literature, which suggests a negative impact of periodontal disease on endothelial function

Post Infection Constrictive Bronchiolitis in an Infant after SARS-CoV-2

La bronquiolitis obliterante se caracteriza por ser una enfermedad respiratoria obstructiva crónica con cambios histológicos irreversibles y de presentación inusual en la población pediátrica por lo cual usualmente es sub diagnosticada, sin embargo, en episodios broncoobstructivos de evolución atípica o severa debe ser considerada como probable diagnóstico. La bronquiolitis obliterante se considera una enfermedad crónica inflamatoria de los bronquiolos que puede presentarse de dos formas histopatológicas ya sea por afectación peribronquiolar desde el epitelio hacia la luz de forma concéntrica (constrictiva) o por ocupación del lumen del bronquiolo dado por proliferación del tejido endoluminal (proliferativa). El diagnóstico se realiza según criterios clínicos y criterios radiológicos (TC de tórax), un puntaje mayor de 7 predice con alta precisión el diagnóstico de bronquiolitis obliterante. Dado que se trata de una enfermedad inflamatoria crónica mediada por la respuesta inmune, el tratamiento esta dirigido a suprimir la respuesta inflamatoria para evitar el daño pulmonar por cambios irreversibles sin embargo, una vez instaurada la enfermedad el tratamiento será sintomático, de soporte y seguimiento de la función pulmonar. A continuación, se presenta el caso de un lactante de 2 meses de edad con antecedente en su periodo neonatal de infección respiratoria por SARS-CoV-2 (COVID-19) en quien se evidenció cambios radiológicos y clínicos compatibles con bronquiolitis constrictiva post infecciosa en su evolución clínica.Q4Neonatos con Bronquiolitis constrictivaBronchiolitis obliterans is a chronic and irreversiblepulmonary disease that leads to obstruction andobliteration of the small airways and that can present by peribronchiolar involvement, from the epitheliumtowards the lumen in a concentric (constrictive), orby occupation of the lumen of the bronchiole, given by proliferation of the endoluminal tissue (proliferative). The lesion at the level of the small airway can occurafter lung or bone marrow transplantation, infections, inhalation of toxic substances, connective tissue diseasesor secondary to drugs. In the pediatric population, the constrictive form secondary to severe respiratory tractinfections, and known as post-infectious bronchiolitisobliterans (PIBO), is the most common and its clinicalpresentation can be highly variable from mild to severe airway obstruction that does not respond to treatmentwith bronchodilators, in addition to hypoxemia, cough andtachypnea. Diagnosis is difficult given the previous need for a lung biopsy, the current absence of biomarkers, andsince its pathophysiology is not clearly understood. The CT as well as a clinical score predict with high precisionthe diagnosis of obliterative bronchiolitis. Treatment isaimed at suppressing the inflammatory response to preventlung damage. We report a case of a 2-month-old infant with a history of respiratory infection due to SARS-CoV-2(COVID-19) in his neonatal period is presented, in whomradiological and clinical changes compatible with PIBO were evidenced.https://orcid.org/0000-0002-5917-8212https://orcid.org/0000-0002-3037-9715https://orcid.org/0000-0003-1627-7971https://orcid.org/0000-0003-3870-4102https://orcid.org/0000-0002-1923-3934Revista Nacional - IndexadaS

Prevalence of sleep complaints in Colombia at different altitudes

AbstractStudy objectivesTo determine the prevalence of sleep complaints in adults in Colombia at different altitudes.DesignCross-sectional, population-based and observational study.SettingUrban areas in three cities (Bogotá, Bucaramanga, Santa Marta) located between 15 and 2640 masl. Subjects Over 18 years old.InterventionsEpworth sleepiness scale (ESS), Pittsburgh sleep quality index (PSQI), Berlin questionnaire, STOP-Bang questionnaire and diagnostic criteria for restless leg syndrome (IRLSSG).Measurements and resultsThe overall prevalence of sleep complaints was 59.6% (CI 95%: 57.3; 61.8%). According to the Pittsburgh scale, 45.3% (CI 95%: 43.0; 47.5) required medical assistance. The Berlin questionnaire indicated that 19.0% (CI 95%: 17.3; 20.8%) had a high risk of sleep apnea (OSA) compared to 26.9% (CI 95%: 24.9; 29.0%) according to STOP-Bang. Among the subjects, 13.7% (CI 95%: 12.3; 15.3%) had excessive daytime sleepiness and 37.7% (CI 95%: 35.5; 39.8%) had a restless leg syndrome. When comparing cities, significant differences in the overall frequency of subjects requiring care were found between Santa Marta (higher frequency) and the other two cities. Differences in sleep problem frequency (Pittsburgh) were observed between Bogota (higher frequency) and Bucaramanga and also between Santa Marta (higher frequency) and the other two cities. The high risk of OSA (STOP-Bang) was different between Bogota (higher frequency) and Bucaramanga and also between Santa Marta (high frequency) and Bucaramanga.ConclusionsWe observed a high prevalence of sleep complaints with significant differences among the cities, indicating a need to pay a greater attention to these problems

Cystic Lymphangioma in the Small Intestine : A Case Report

En este artículo se describe el raro caso de una niña de 7 años de edad en quien se realizó un diagnóstico histopatológico final de linfangioma quístico en el intestino delgado. Los linfangiomas son lesiones benignas de origen vascular que muestran diferenciación linfática y pueden ocurrir en muchas regiones anatómicas, pero los del tubo digestivo son poco frecuentes. Dada la localización atípica y los hallazgos radiológicos, se ilustra este caso documentado, seguido por una revisión de la literatura.Reporte de caso3556-3560In this article, we report a rare case of a 7-year old female patient with a final histopathological diagnosis of cystic lymphangioma in the small intestine.
