Metabolic and physiological adaptations of microalgal growth-promoting bacterium Azospirillum brasilense growing under biogas atmosphere: a microarray-based transcriptome analysis.

Using microalgal growth-promoting bacteria (MGPB) to improve the cultured microalga metabolism during biotechnological processes is one of the most promising strategies to enhance their benefits. Nonetheless, the culture condition effect used during the biotechnological process on MGPB growth and metabolism is key to ensure the expected positive bacterium growth and metabolism of microalgae. In this sense, the present research study investigated the effect of the synthetic biogas atmosphere (75% CH4-25% CO2) on metabolic and physiological adaptations of the MGPB Azospirillum brasilense by a microarray-based transcriptome approach. A total of 394 A. brasilense differentially expressed genes (DEGs) were found: 201 DEGs (34 upregulated and 167 downregulated) at 24 h and 193 DEGs (140 upregulated and 53 downregulated) under the same conditions at 72 h. The results showed a series of A. brasilense genes regulating processes that could be essential for its adaptation to the early stressful condition generated by biogas. Evidence of energy production is shown by nitrate/nitrite reduction and activation of the hypothetical first steps of hydrogenotrophic methanogenesis; signal molecule modulation is observed: indole-3-acetic acid (IAA), riboflavin, and vitamin B6, activation of Type VI secretion system responding to IAA exposure, as well as polyhydroxybutyrate (PHB) biosynthesis and accumulation. Moreover, an overexpression of ipdC, ribB, and phaC genes, encoding the key enzymes for the production of the signal molecule IAA, vitamin riboflavin, and PHB production of 2, 1.5 and 11 folds, respectively, was observed at the first 24 h of incubation under biogas atmosphere Overall, the ability of A. brasilense to metabolically adapt to a biogas atmosphere is demonstrated, which allows its implementation for generating biogas with high calorific values and the use of renewable energies through microalga biotechnologies.

Soluble receptor for advanced glycation end-products (sRAGE) in childhood obesity: association with gene expression of RAGE and cardiometabolic markers / Receptor soluble para productos finales de glicación avanzada (sRAGE) en la obesidad infantil:asociación con la expresión génica de RAGE y marcadores cardiometabólicos

Introduction: advanced glycation end-products (AGEs) interact with the receptor for AGEs (RAGE). Full-length RAGE is associated with intracellular signal transduction, and soluble-RAGE (sRAGE) lacks the transmembrane and cytoplasmic domains, acting as a competitive inhibitor ofAGEs-RAGE binding. sRAGE levels in healthy children are associated with cell surface expression of RAGE. However, the expression of RAGE hasnot been explored in childhood obesity.Objective: the study aim was to evaluate the sRAGE levels and the gene expression of RAGE in children and its association with cardiometabolicmarkers.Methods: this is a cross-sectional study with 6-11-year children, 20 with overweight and 20 with obesity. Anthropometric measurements includedwaist circumference (cm) (WC), neck circumference (NC), weight (kg), fat mass (%), trunk fat (kg), muscular mass (kg), height (cm), and bodymass index (BMI) (kg/m2). Blood samples following an overnight fast were collected to measure glucose (mg/dl) and lipid profile with colorimetricmethods. sRAGE was determined in serum using the enzyme-linked immunosorbent assay (ELISA). Quantitative reverse transcription (RT-qPCR)was performed to analyze RAGE transcripts in peripheral blood mononuclear cells isolated by Ficoll®-Hypaque.Results: we found higher RAGE (p = 0.0315) and lower sRAGE (p = 0.0305) levels in the obesity group. sRAGE level showed a negative correlation with RAGE (r = -0.35) and BMI (r = -0.24), and positive with HDL-cholesterol (r = 0.29). Regression analysis suggests that HDL-C andRAGE levels are predictors of sRAGE levels.Conclusions: expression of RAGE is associated with lower sRAGE levels in childhood obesity. Moreover, obese children show higher cardiometabolic risk markers, and a positively associated with sRAGE. (AU)

Introducción: las complicaciones por otitis media aguda tienen una incidencia menor a un 1%. Aun así, se describe en literatura una mortalidad de un 5%. Actualmente existe escasa evidencia sobre estas complicaciones en nuestra realidad local. Objetivo: describir las de complicaciones de otitis media aguda según tipo, sexo, síntomas de ingreso, exámenes solicitados y tratamiento. Material y Métodos: estudio descriptivo retrospectivo de revisión de fichas clínicas que incluyó pacientes que ingresaron al Hospital Clínico de la Pontificia Universidad Católica de Chile con diagnóstico de otitis media aguda entre el 1 enero de 2000 hasta el 30 de julio de 2022. Resultados: se obtuvieron 71 pacientes ingresados por complicación de otitis media aguda. La edad media fue de 26,79 años, con 46 mujeres y 25 hombres. Se observaron complicaciones extracraneales, intracraneales y complicaciones simultáneas. Las complicaciones más frecuentes fueron la laberintitis y mastoiditis sin reportar casos de mortalidad. Discusión: actualmente existe escasa información sobre complicaciones de otitis media aguda y su epidemiología a nivel local. Las complicaciones extracraneales fueron más frecuentes: de ellas, la laberintitis y la mastoiditis agudas. El diagnóstico es clínico con apoyo de exámenes tanto de laboratorio, audiovestibulares e imágenes. Con respecto al tratamiento quirúrgico, se debe evaluar caso a caso y debe incluir miringotomía con o sin instalación de tubo de ventilación y mastoidectomía en casos refractarios. Es importante la sospecha y la derivación precoz

Introduction: Complications due to acute otitis media have an incidence of less than 1%. Nevertheless, it is described in the literature as having a 5% mortality rate. Currently, there is little evidence of these complications in our local reality. Objective: Describe the complications of acute otitis media based on its type, patient gender, admission symptoms, requested exams, and treatment. Material and Methods: Retrospective and descriptive study of patients' medical records admitted at the "Hospital Clínico de la Pontificia Universidad Católica de Chile" who were diagnosed with acute otitis media from January 1st, 2000, to July 30th, 2022. Results: There were 71 patients admitted due to complications of acute otitis media. On average, they were 26.29 years old; 46 were women, and 25 were men. Extracranial, intracranial, and simultaneous complications were observed. The most frequent ones were labyrinthitis and mastoiditis, without any mortality cases reported. Discussion: Currently, there is scarce information about the complications of acute otitis media and its local epidemiology. Extracranial complications were the most frequent: acute labyrinthitis and mastoiditis. The clinical diagnosis is supported by laboratory, audiovestibular, and image tests. Regarding surgical treatment, each patient must be evaluated independently. It should include myringotomy with or without a ventilation tube and mastoidectomy in refractory cases. It is crucial to detect it early and proceed with a medical referral.

Elimination of E. faecalis and C. albicans Biofilm: A comparison between single and multiple file systems in an Ex Vivo study

To evaluate whether the WaveOne Gold and Reciproc single file instrumentation systems, are effective in reducing the microbial load of a mixed biofilm and the cleaning of apical third compared to the Twisted File Adaptive system (multiple- file system). Seventy mesial roots of the first and second molars were included and randomly divided into three experimental groups (n=20, n=10 controls). Biofilms were formed inside canals over 31 days. After instrumentation with the unique file systems, WaveOne Gold and Reciproc and the multiple file system Twisted File Adaptive, using 2.25% sodium hypochlorite as an irrigant in all cases, a count of colony forming units was performed using serial dilutions, cleaning of the apical third was evaluated using scanning electron microscopy. Comparisons amongst groups were made by using parametric and non-parametric statistics, according to a normal or non-normal data distribution, respectively. No significant differences in the reduction of the microbial load after employing a single-file system in comparison to the multiple-file system were found; in addition, the cleaning of the apical third was similar for the three different instrumentation systems. The single-file system is equal in effectiveness compared with the multiple-file system in reducing the microbial load.

Evaluar si los sistemas de instrumentación de lima única, como WaveOne Gold y Reciproc son efectivos para reducir la carga microbiana de un biofilm mixto y la limpieza del tercio apical, comparado con los sistemas de limas múltiples, como Twisted File Adaptive. Setenta raíces mesiales de primeros y segundos molares fueron incluidos y divididos de forma aleatoria en tres grupos experimentales (n=20, n=10 controles). El biofilm fue formado en el interior de los conductos durante 31 días. Después se instrumentó con los sistemas de lima única (WaveOne Gold y Reciproc) y el sistema de limas múltiples Twisted File Adaptive, usando hipoclorito de sodio al 2.5% en todos los casos. El conteo de unidades formadoras de colonias se realizó usando diluciones seriales, la limpieza del tercio apical se evaluó empleando el microscopio electrónico de barrido. La comparación entre grupos se realizó con pruebas paramétricas y no paramétricas, de acuerdo con la distribución normal y no normal de los datos, respectivamente. No hubo una diferencia significativa en la reducción de la carga microbiana después de emplear los sistemas de lima única en comparación a los de limas múltiples, además, la limpieza del tercio apical fue similar en los 3 diferentes sistemas de instrumentación. Los sistemas de lima única son igual de efectivos para reducir la carga microbiana comparados con los sistemas de limas múltiples.

Polymorphisms -374 T/A and -429 T/C of the Receptor for Advanced Glycation End-Products (RAGE) and Serum Levels of RAGE (sRAGE) Are Not Associated with Metabolic Syndrome.

RAGE is a multi-ligand transmembrane glycoprotein that promotes biological signals associated with inflammatory responses and degenerative diseases. sRAGE is a soluble variant, proposed as an inhibitor of RAGE activity. -374 T/A and -429 T/C polymorphisms of the advanced glycation end products receptor AGER gene are associated with the development of some diseases, such as type of cancer, cardiovascular disease, and micro and macrovascular disease in diabetes among others but their role in metabolic syndrome (MS) is still unknown. We studied 80 healthy men without MS, and 80 men with MS according to the harmonized criteria. -374 T/A and -429 T/C polymorphisms were genotyped by RT-PCR, and sRAGE was measured by ELISA. Allelic and genotypic frequencies did not differ between Non-MS and MS groups (-374 T/A p = 0.48, p = 0.57 and -429 T/C p = 0.36, p = 0.59). Significant differences were found in fasting glucose levels and diastolic blood pressure among the genotypes of the -374 T/A polymorphism in the Non-MS group (p < 0.01 and p = 0.008). Glucose levels were different between -429 T/C genotypes in the MS group (p = 0.02). sRAGE levels were similar in both groups, but in the Non-MS group showed a significant difference between individuals with only 1 or 2 components of the metabolic syndrome (p = 0.047). However, no associations of any SNP with MS were found (recessive model p = 0.48, dominant model p = 0.82 for -374 T/A; recessive model p = 0.48, dominant model p = 0.42 for -429 T/C). -374 T/A and -429 T/C polymorphisms are not associated with MS in Mexican population and have no influence on serum sRAGE levels.

Nonadherence to systemic immune-modifying therapy in people with psoriasis during the COVID-19 pandemic: findings from a global cross-sectional survey.

BACKGROUND: Nonadherence to immune-modifying therapy is a complex behaviour which, before the COVID-19 pandemic, was shown to be associated with mental health disorders in people with immune-mediated diseases. The COVID-19 pandemic has led to a rise in the global prevalence of anxiety and depression, and limited data exist on the association between mental health and nonadherence to immune-modifying therapy during the pandemic. OBJECTIVES: To assess the extent of and reasons underlying nonadherence to systemic immune-modifying therapy during the COVID-19 pandemic in individuals with psoriasis, and the association between mental health and nonadherence. METHODS: Online self-report surveys (PsoProtectMe), including validated screens for anxiety and depression, were completed globally during the first year of the pandemic. We assessed the association between anxiety or depression and nonadherence to systemic immune-modifying therapy using binomial logistic regression, adjusting for potential cofounders (age, sex, ethnicity, comorbidity) and country of residence. RESULTS: Of 3980 participants from 77 countries, 1611 (40.5%) were prescribed a systemic immune-modifying therapy. Of these, 408 (25.3%) reported nonadherence during the pandemic, most commonly due to concerns about their immunity. In the unadjusted model, a positive anxiety screen was associated with nonadherence to systemic immune-modifying therapy [odds ratio (OR) 1.37, 95% confidence interval (CI) 1.07-1.76]. Specifically, anxiety was associated with nonadherence to targeted therapy (OR 1.41, 95% CI 1.01-1.96) but not standard systemic therapy (OR 1.16, 95% CI 0.81-1.67). In the adjusted model, although the directions of the effects remained, anxiety was not significantly associated with nonadherence to overall systemic (OR 1.20, 95% CI 0.92-1.56) or targeted (OR 1.33, 95% CI 0.94-1.89) immune-modifying therapy. A positive depression screen was not strongly associated with nonadherence to systemic immune-modifying therapy in the unadjusted (OR 1.22, 95% CI 0.94-1.57) or adjusted models (OR 1.14, 95% CI 0.87-1.49). CONCLUSIONS: These data indicate substantial nonadherence to immune-modifying therapy in people with psoriasis during the pandemic, with attenuation of the association with mental health after adjusting for confounders. Future research in larger populations should further explore pandemic-specific drivers of treatment nonadherence. Clear communication of the reassuring findings from population-based research regarding immune-modifying therapy-associated adverse COVID-19 risks to people with psoriasis is essential, to optimize adherence and disease outcomes.

Response to Comment on "Feasibility of Raman spectroscopy as a potential in vivo tool to screen for pre-diabetes and diabetes".

This letter aims to reply to Bratchenko and Bratchenko's comment on our paper "Feasibility of Raman spectroscopy as a potential in vivo tool to screen for pre-diabetes and diabetes." Our paper analyzed the feasibility of using in vivo Raman measurements combined with machine learning techniques to screen diabetic and prediabetic patients. We argued that this approach yields high overall accuracy (94.3%) while retaining a good capacity to distinguish between diabetic (area under the receiver-operating curve [AUC] = 0.86) and control classes (AUC = 0.97) and a moderate performance for the prediabetic class (AUC = 0.76). Bratchenko and Bratchenko's comment focuses on the possible overestimation of the proposed classification models and the absence of information on the age of participants. In this reply, we address their main concerns regarding our previous manuscript.

Cuidado espiritual en estudiantes de enfermería: estudio cualitativo / Spiritual Care in Nursing Students: Qualitative Study / Cuidado espiritual em estudantes de enfermagem: um estudo qualitativo

Introducción. La atención de la dimensión espiritual en pacientes y familias es fundamental como parte del papel activo de los profesionales de enfermería en la satisfacción de las necesidades espirituales de los pacientes. Objetivo. Comprender las actitudes frente al cuidado espiritual de los profesionales de enfermería en formación. Metodología. Estudio de abordaje cualitativo, con análisis de contenido, con población de 20 estudiantes de educación superior de Enfermería, con un muestreo por conveniencia. Se realizaron entrevistas semiestructuradas y dos grupos focales para indagar sobre el autoconocimiento espiritual y las concepciones del cuidado espiritual, tomando como referencia los conceptos teóricos propuestos por McSherry. El análisis de los datos inicialmente se hizo de forma inductiva, con ayuda del software Iramuteq. Resultados. La espiritualidad se considera una dimensión intrapersonal donde se reconoce la necesidad de explorar su propia espiritualidad para acercarse a la percepción espiritual del paciente. Aprender de las crisis para el desarrollo de la espiritualidad personal y encontrarse desde la naturaleza fueron parte de las categorías encontradas. Discusión. La concepción del cuidado espiritual para los estudiantes como dimensión intrapersonal, les permite distinguir entre la espiritualidad y la religiosidad. Este es un aspecto que se ha podido ver durante el desarrollo de las prácticas formativas, ya que se han encontrado personas muy religiosas, así como otras que no lo son. Conclusiones. Se hace referencia a la relación entre lo espiritual y lo corpóreo y aunque existe una diferencia entre religión y espiritualidad, los dos conceptos deben ser valorados a nivel personal.

Introduction. Attention to the spiritual dimension of patients and families is fundamental as part of the active role of nursing professionals in satisfying the spiritual needs of patients. Objective. To understand the attitudes towards spiritual care of nursing professionals in training. Methodology. Qualitative study with content analysis, with a population of 20 higher education Nursing students, with convenience sampling. Semi-structured interviews and two focus groups were held to explore spiritual self-knowledge and the conceptions of spiritual care, using the theoretical concepts proposed by McSherry as a reference. Data was initially analyzed inductively, with help from the Iramuteq software. Results. Spirituality is considered an intrapersonal dimension in which the need to explore one's own spirituality in recognized, in order to approach the spiritual perception of the patient. Learning about crises for the development of a personal spirituality and finding oneself through nature were part of the observed categories. Discussion. The conception of spiritual care as an intrapersonal dimension helps students differentiate between spirituality and religion. This aspecto has been observable during educational practice, since there were some very religious people and others who were not. Conclusions. Reference is made to the relationship between that which is spiritual and corporeal, and though there is a difference between spirituality and religion, both concepts must be assessed personally.

Introduction: Spiritual care can be considered a basic component of the philosophy of holistic care. Objective: Identify intervention studies with educational perspectives and strategies for developing spiritual care competencies in nurses and nursing students. Materials and methods: Integrative review of literature conducted in the period 2001-2021, in the databases PubMed, ProQuest, Scopus, LILACS, and VHL (Virtual Health Library). PRISMA statement guidelines were followed for the review, and it was based on Whittemore and Knafl's stages for integrative reviews: problem formulation, literature search, evaluation of data, data analysis, and presentation of results. Results: Ten published intervention articles were found. Education for the development of spiritual care competencies has been provided by educational programs and activities in undergraduate nursing programs and with professional nurses in practice. Instructional strategies include specific courses, short sessions, or programs throughout the curriculum. Interventions have an impact on skills and knowledge. Students' individual spirituality is a predictor of the competence to provide spiritual care. Conclusions: There is evidence of strategies to develop spiritual care competencies in nursing students and professionals, but publications on the subject are scarce. Therefore, implementing new and more rigorous strategies that allow the development of competencies for approaching spirituality in nursing is required.

Feasibility of Raman spectroscopy as a potential in vivo tool to screen for pre-diabetes and diabetes.

In this article, we investigated the feasibility of using Raman spectroscopy and multivariate analysis method to noninvasively screen for prediabetes and diabetes in vivo. Raman measurements were performed on the skin from 56 patients with diabetes, 19 prediabetic patients and 32 healthy volunteers. These spectra were collected along with reference values provided by the standard glycated hemoglobin (HbA1c) assay. A multiclass principal component analysis and support vector machine (PCA-SVM) model was created from the labeled Raman spectra and was validated through a two-layer cross-validation scheme. Classification accuracy of the model was 94.3% with an area under the receiver operating characteristic curve AUC of 0.76 (0.65-0.84) for the prediabetic group, 0.86 (0.71-0.93) for the diabetic group and 0.97(0.93-0.99) for the control group. Our results suggest the feasibility of using Raman spectroscopy for the classification of prediabetes and diabetes in vivo.

Factors related to healthcare costs of road traffic accidents in Bucaramanga, Colombia.

OBJECTIVE: To determine the factors related to overall healthcare costs of road traffic accidents in Bucaramanga, Colombia. METHODS: A descriptive cross-sectional study was conducted through the analysis of road traffic accident records that took place in 2019 in Bucaramanga, Colombia. Cost quartiles in dollars were compared using Pearson's chi-squared and Fisher's exact tests. Odds ratios were also calculated in logistic regression. RESULTS: 3,150 road accidents were reported in 2019 involving 7,038 people, of which 812 had information related to healthcare costs in health care institutions. The median cost was 56.59 USD (RI = 29.35-140.15), average cost of 290.11 USD ± 731.22 (95%CI: 239.74-340.48). A higher possibility to be in the 4th quartile was found when persons were under 18 years of age (OR = 4.88; 95%CI: 1.30-18.32) or 46-60 years (OR = 3.66; 95%CI: 1.01-13.30), the type of vehicle involved is motorcycle (OR = 2.79; 95%CI: 1.25-6.24), bicycle (OR = 7.66; 95%CI: 2.70-21.68), having a head injury (OR = 4.50; 95%CI: 2.61-7.76) and hypothetical drunk driving (OR = 12.44; 95%CI: 2.01-76.87). CONCLUSIONS: Relevant factors in healthcare costs were riding a motorcycle or bicycle, having a head injury, being under 18 years of age or 46 to 60 years of age and hypothetical drunk driving. It is important to implement prevention measures based on identified factors to reduce road accident rate and therefore, its socioeconomic costs.

mediante el Aprendizaje Basado en Problemas (ABP) y basada en la Teoría de Autocuidado de Orem sobre la agencia de autocuidado en estudiantes de Enfermería de dos universidades colombianas. Método: estudio cuasiexperimental antes/después multicéntrico realizado en 2019. La población fueron los 56 estudiantes del primer semestre de Enfermería de dos universidades colombianas. Se realizó la intervención “Hacia el cuidado de la vida” con 12 sesiones de dos horas durante 13 semanas sobre autocuidado mental y espiritual, estilos de vida saludable, autocuidado corporal y autocuidado social mediante ABP. Se midieron variables sociodemográficas, académicas y de hábitos de consumo. La agencia de autocuidado se midió basal (B) y en la última sesión (P) mediante la escala ASA-B (muy baja: 1-24, baja: 25-48, buena: 49-72 o muy buena: 73-96 puntos). Se efectuó estadística descriptiva y bivariante. Resultados: completaron el estudio 40 personas. El 82,1% era mujer, con una edad mediana de 18. La puntuación global de la escala ASA-B se incrementó de manera estadísticamente significativa de manera global [B: X= 71,1 (DE= 0,73) y P: X= 75,6 (DE= 1,07); p< 0,001] y en las mujeres, de 18 a 20 años, solteras, con puntuación en Prueba Saber 11 en cuartil 1 o 2, antecedentes de ingesta de alcohol o de bebidas energizantes (p< 0,05). No varió la puntuación en función de la pertenencia a equipos deportivos, federaciones estudiantiles o grupos religiosos. Conclusión: la intervención educativa basada en la Teoría de Autocuidado y ABP aplicada a estudiantes de primer semestre de Enfermería mejoró su agencia de autocuidado.(AU)

Objective: to determine the impact of an educational intervention through Problem-Based Learning (PBL) and based on Orem’s Self-Care Theory on the self-care agency in Nursing students from two Colombian universities. Method: a multicentre quasi-experimental before-and-after study conducted on 2019. The population included the 56 students of the first Nursing semester from two Colombian universities. The “Hacia el cuidado de la vida” (“Towards Life Care”) intervention was conducted, with 12 two-hour sessions during 13 weeks on mental and spiritual self-care, healthy lifestyles, body self-care and social self-care through PBL. Sociodemographic and academic variables were measured, as well as consumer habits. The Self-Care Agency was measured at baseline (B) and at the last session (P) through the ASA-B scale (very low: 1-24, low: 25-48, good: 49-72 or very good: 73-96 scores). Descriptive and bivariate statistics were applied. Results: forty (40) persons completed the study; 82.1% were female, with 18 years as median age. The overall score in the ASA-B scale was increased overall in a statistically significant way [B: X= 71.1 (SD= 0.73) and P: X= 75.6 (SD= 1.07); p< 0.001] and in 18-to-20-year old single women, with a score of 11 in knowledge test in first or second quartile, past history of using alcohol or energy drinks (p< 0.05). There was no variation in score in terms of affiliation to sport teams, student federations or religious groups. Conclusion: the educational intervention based on the self-care theory and PBL applied to students in their first Nursing semester improved their self-care agency.(AU)

Aerosol box for intubation of patients with suspected COVID-19: simulation study / Caja de aerosol para la intubación de pacientes con sospecha de COVID-19: Un estudio de simulación

Abstract Introduction Endotracheal intubation is a procedure associated with a high level of exposure to the COVID-19 virus. This has led to the search of alternatives to reduce the risk of contamination, including the so-called aerosol box. Objective To compare time and difficulty of orotracheal intubation when using the aerosol box in a simulated setting. Methodology Observational study conducted with the participation of 33 anesthetist physicians and anesthesia residents; groups were compared in terms of time and intubation difficulty using a conventional Macintosh laryngoscope and the McGRATH™ MAC (Medtronic) videolaryngoscope with or without aerosol box. In order to determine performance with the intubation maneuver, crude hazard ratios were estimated, and a Cox multivariate regression model was built, adjusted by anesthetist years of experience and difficulties during the procedure. Results On average, the aerosol box increased intubation time by 7.57 seconds (SD 8.33) when the videolaryngoscope was used, and by 6.62 (SD 5.74) with the Macintosh. Overall, 132 intubations were performed, with 121 successful and 6 failed first-time attempts (4 with the use of the aerosol box); 16 participants (48.48%) reported difficulty handling the box. With the use of the Macintosh, intubation was found to be faster than with the videolaryngoscope (cHR: 1.36 [95% CI 0.64-2.88]; adjusted HR: 2.20 [95% CI 0.73-6.62]). Conclusions The use of the aerosol box and personal protective equipment in a simulation setting hinders the intubation maneuver and may result in protracted execution time.

Resumen Introducción La intubación endotraqueal es un procedimiento que se relaciona con alto nivel de exposición al virus de COVID-19, llevando a la búsqueda de alternativas para disminuir el riesgo de contaminación, entre ellas la llamada Caja de aerosoles. Objetivo Comparar el tiempo y dificultad en la intubación orotraqueal usando la caja de aerosoles en escenarios simulados. Metodología Estudio observacional, con participación de 33 médicos anestesiólogos y residentes de anestesia; se compararon los grupos en tiempo y dificultad de intubación con uso de laringoscopio convencional Macintosh y videolaringoscopio McGRATH™ MAC (Medtronic) utilizando la caja de aerosoles y sin ella. Para determinar el rendimiento en la maniobra de intubación se calcularon Hazard ratios crudos, se construyó modelo multivariado de Regresion de Cox ajustado por años de experiencia como anestesiólogo y dificultades durante el procedimiento. Resultados La caja de aerosoles aumentó en promedio el tiempo en segundos para la intubación con video-laringoscopio en 7,57 (DE: 8,33) y con Macintosh 6,62 (DE: 5,74). Se llevaron a cabo 132 intubaciones, 121 exitosas en el primer intento y 6 fallidas (4 con el uso de la caja de aerosoles). 16 participantes reconocieron alguna dificultad al manipular la caja (48,48 %). Con el uso de Macintosh se identificó tendencia a la intubación más rápido que con el videolaringoscopio (HRc: 1,36 [IC 95 %: 0,64-2,88]; HR ajustado: 2,20 [IC 95 %: 0,73-6,62]). Conclusiones Utilizar la caja de aerosoles y equipo de protección personal en un escenario simulado dificulta la maniobra de intubación y puede prolongar el tiempo de ejecución.
