ENDS consumption in students of higher education: Phenomenon on the rise during the COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic triggered transformations in the population's lifestyles, including electronic nicotine delivery system (ENDS) consumption. The aim of the study was to determine associations between ENDS consumption habits and lifestyles among higher education students in Bogotá, Colombia. METHODS: This study employed a cross-sectional analytical design, based on a self-administered online survey, conducted in 2021, among students aged 18-59 years. The sample size was 3985 students. Statistical analysis was done through frequency studies, hypothesis testing and a multivariate-penalized logistic regression model (firthlogit), based on the Akaike information criterion (AIC). RESULTS: A total of 3573 students completed the survey, 61.5% were female, 55.3% were young (aged 18-26 years), and 44.6% were adults (aged 27-59 years). The prevalence of ENDS use during the pandemic was 7.3%. Age was negatively associated with ENDS use, as young people had a higher likelihood of using these devices. The likelihood of ENDS use was negative among females (OR=0.38; 95% CI: 0.2-0.5). In contrast, it was positive in students with a history of psychoactive substance abuse and/or dependence (OR=3.59; 95% CI: 1.0-12.0), students who had tried conventional cigarettes (OR=5.12; 95% CI: 3.0-8.5), participants who smoked tobacco during the pandemic (OR=3.15; 95% CI: 2.3-4.2), those who studied virtually (OR=1.52; 95% CI: 1.0-2.3), participants who lived with other ENDS users (OR=3.86; 95% CI: 2.8-5.2) and students with negative perception of impacts on their mental health (OR=1.48; 95% CI: 1.1-1.9). CONCLUSIONS: Being male, aged <26 years, having a history of substance use, having tried conventional cigarettes, pandemic tobacco use, and having lived with other ENDS users, were the main factors associated with pandemic ENDS use. Studying the consumption habits of students in response to lifestyle changes, is fundamental for the formulation of strategies to reduce the development of addictive behaviors, especially in young students during the pandemic.

Addressing Severe Mental Illness Rehabilitation in Colombia, Costa Rica, and Peru.

Many Latin American countries face the challenge of caring for a growing number of people with severe mental illnesses while promoting deinstitutionalization and community-based care. This article presents an overview of current policies that aim to reform the mental health care system and advance the employment of people with disabilities in Colombia, Costa Rica, and Peru. The authors conducted a thematic analysis by using public records and semistructured interviews with stakeholders. The authors found evidence of supported employment programs for vulnerable populations, including people with disabilities, but found that the programs did not include people with severe mental illnesses. Five relevant themes were found to hamper progress in psychiatric vocational rehabilitation services: rigid labor markets, insufficient advocacy, public subsidies that create conflicting incentives, lack of deinstitutionalized models, and lack of reimbursement for evidence-based psychiatric rehabilitation interventions. Policy reforms in these countries have promoted the use of medical interventions to treat people with severe mental illnesses but not the use of evidence-based rehabilitation programs to facilitate community integration and functional recovery. Because these countries have other supported employment programs for people with nonpsychiatric disabilities, they are well positioned to pilot individual placement and support to accelerate full community integration among individuals with severe mental illnesses.

Adaptation to Spanish and criterion validity of a scale for the screening of emotional and behavioral problems in early childhood

Introduction: Early identification of emotional and behavioral risk in children can contribute to the development of strategies that promote mental health from early childhood. In Colombia, we do not count with a validated screening tool for emotional and behavioral problems in this population. Objectives: To identify, adapt, and establish evidence for the criterion validity of a screening tool for emotional and behavioral problems in less than 6-year-old children. Materials and methods: We selected the Early Childhood Screening Assessment (ECSA) after a literature review and expert consensus and then we undertook its linguistic adaptation. For criterion validity, we used the Receiver Operating Characteristic (ROC) comparing the scale with the Child Behavior Checklist (CBCL 1,5-5). The sample included 206 caregivers of children between 1.5 and 6 years of age from the city of Tunja and the municipality of Sopó. Results: The ECSA showed a good correlation with the total t-score of the CBCL 1,5-5 (Spearman rho= 0,75, p<0,01). The scale showed a sensitivity of 86% and a specificity of 82% at a cut-off point of 24. Conclusion: In this first adaptation to Spanish and validation study of the ECSA scale, we found good sensitivity and specificity values for the screening of emotional and behavioral problems in early childhood.

Adaptación al español y validación de criterio de una escala para la tamización de problemas emocionales y del comportamiento en la primera infancia / Adaptation to Spanish and criterion validity of a scale for the screening of emotional and behavioral problems in early childhood

Resumen Introducción. La detección temprana del riesgo de problemas emocionales y del comportamiento en niños puede contribuir al desarrollo de estrategias que promuevan la salud mental desde la primera infancia. En Colombia no existe una herramienta validada para dicha detección. Objetivos. Seleccionar, adaptar y establecer la validez de criterio de una escala de tamización de problemas emocionales y del comportamiento en niños menores de seis años. Materiales y métodos. A partir de una revisión de la literatura y un consenso de expertos, se seleccionó la herramienta Early Childhood Screening Assessment (ECSA). Posteriormente, se llevó a cabo su adaptación lingüística y se determinó la validez de criterio mediante una curva de características de recibidor-operador (Receiver Operating Characteristic, ROC), y se la comparó con el cuestionario Child Behavior Checklist (CBCL 1,5-5). En el estudio participaron 206 cuidadores de niños entre el año y medio y los seis años de edad de la ciudad de Tunja y el municipio de Sopó. Resultados. La puntuación del ECSA presentó una buena correlación con la puntuación t total del CBCL 1,5-5 (ro de Spearman=0,75; p<0,01). La escala ECSA tuvo una sensibilidad de 86 % y una especificidad de 82 % al establecer un punto de corte de 24 para la población estudiada. Conclusión. En este primer estudio de adaptación y validación de la versión en español de la escala ECSA, se detectaron buenos valores de sensibilidad y especificidad para la tamización de problemas emocionales y del comportamiento en la primera infancia.

Estandarización y aplicación de la técnica de PCR – anidado para la detección de Mycoplasma hyopneumoniae / Standardization and application of the PCR – nested technique for the detection of Mycoplasma hyopneumoniae

El Mycoplasma hyopneumoniae es el agente causal de la Neumonía enzoótica porcina, una de las enfermedades más importantes en la industria porcina. En la actualidad, el proceso de diagnóstico ante-mortem es una de las principales dificultades, dadas la poca sensibilidad y especificidad de las técnicas que se utilizan. El propósito de esta investigación fue estandarizarla técnica de Reacción en Cadena de la Polimerasa (PCR) anidada para la detección de Mycoplasma hyopneumoniae, utilizando diferentes métodos de extracción del ADN, tanto comerciales como convencionales. Para determinar la sensibilidad de la técnica se realizaron diluciones seriadas al cultivo de Mycoplasma hyopneumoniae, cepa J, mantenida en medioFriis. También se evaluaron algunas modificaciones hechas a la mezcla de la reacción dePCR tradicional reportadas en la literatura y, una vez ajustada, la técnica fue aplicada enmuestras clínicas como hisopados nasales y lavados traqueobronquiales. Los mejores resultados fueron obtenidos cuando el ADN se extrajo de la bacteria por calor yse trató con proteinasa K para luego ser utilizado en una reacción de PCR - anidado que nocontenía estabilizadores de la Taq-polimerasa, como el glicerol o la seroalbúmina bovina.Bajo estas condiciones, se logró detectar M. hyopneumoniae hasta la dilución de 10-5 de uncultivo puro de la cepa J de referencia y también a partir de algunas muestras clínicas...
