A landscape of liver cirrhosis and transplantation in Mexico: changing leading causes and transplant as response.

Liver cirrhosis causes include alcoholism, viral infections (hepatitis B virus (HBV) and hepatitis C virus (HCV)), alcohol-associated liver disease (ALD), and metabolic dysfunction associated with steatotic liver disease (MASLD), among others. Cirrhosis frequency has increased in recent years, with a prevalence of 1,395 cases per 100,000 and a mortality rate of 18 per 100,000, which corresponded to 1,472,000 deaths during 2017. In Mexico, liver disease is a public health problem since it was associated to 41,890 deaths in 2022, including liver cirrhosis (>25,000) and ALD (14,927). This represents 114 individuals daily due to these causes, and correspond to the 4th to 5th place of all causes. The global prevalence of MASLD is estimated to 25% of the world's population, while in pediatric population could be higher. In Mexican population is more prevalent since estimations are up to 41.3% in 2023. Alcohol consumption, a global health issue due to its high prevalence and associated morbidities, is associated to ALD in 32.9%, with a mortality rate of 23.9%, primarily due to liver-related causes. In Mexico, ALD is present in 23% of all cirrhosis cases. already surpassed by hepatitis B cases in 2009. HCV and HBV frequencies changed due programs implementing screening detection, vaccines and direct-acting antivirals during the last years. A switch of causes has occurred, increasing MASLD and diminishing viral causes. Efficient performed liver transplantation has grown as response to increasing cirrhosis cases, including recent authorized centers. These efforts are necessary, whereas preventive strategies should be implemented according to leading causes.

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.

Introduction: 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 of AGEs-RAGE binding. sRAGE levels in healthy children are associated with cell surface expression of RAGE. However, the expression of RAGE has not 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 cardiometabolic markers. Methods: this is a cross-sectional study with 6-11-year children, 20 with overweight and 20 with obesity. Anthropometric measurements included waist circumference (cm) (WC), neck circumference (NC), weight (kg), fat mass (%), trunk fat (kg), muscular mass (kg), height (cm), and body mass index (BMI) (kg/m2). Blood samples following an overnight fast were collected to measure glucose (mg/dl) and lipid profile with colorimetric methods. 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 and RAGE 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.

Introducción: Introducción: los productos finales de glicación avanzada (AGE) interactúan con el receptor de AGE (RAGE). El RAGE de longitud completa está asociado con la transducción de señales intracelulares y el RAGE soluble (sRAGE) carece de los dominios transmembrana y citoplásmico, actuando como un inhibidor competitivo de la unión de AGE-RAGE. Los niveles de sRAGE en niños sanos están asociados con la expresión de RAGE en la superficie celular. Sin embargo, la expresión de RAGE no se ha explorado en la obesidad infantil. Objetivo: el objetivo del estudio fue evaluar los niveles de sRAGE y la expresión génica de RAGE en niños y su asociación con marcadores cardiometabólicos. Métodos: se trata de un estudio transversal con niños de seis a once años, 20 con sobrepeso y 20 con obesidad. Las medidas antropométricas incluyeron la circunferencia de la cintura (cm) (CC), la circunferencia del cuello (NC), el peso (kg), la masa grasa (%), la grasa del tronco (kg), la masa muscular (kg), la altura (cm) y el índice de masa corporal (IMC) (kg/m2). Se tomaron muestras de sangre después de una noche de ayuno para medir glucosa (mg/dl) y el perfil de lípidos con métodos colorimétricos. Los sRAGE se determinaron en suero utilizando un ensayo inmunoabsorbente ligado a enzimas (ELISA). Se realizó una transcripción inversa cuantitativa (RT-qPCR) para analizar los transcritos de RAGE en células mononucleares de sangre periférica aisladas por Ficoll®-Hypaque. Resultados: encontramos niveles más altos de RAGE (p = 0,0315) y más bajos de sRAGE (p = 0,0305) en el grupo de obesidad. El nivel de sRAGE mostró una correlación negativa con RAGE (r = -0,35) e IMC (r = -0,24), y positiva con el colesterol HDL (r = 0,29). El análisis de regresión sugiere que los niveles de HDL-C y RAGE predicen los niveles de sRAGE. Conclusiones: la expresión de RAGE se asocia con niveles más bajos de sRAGE en la obesidad infantil. Además, los niños obesos muestran marcadores de riesgo cardiometabólico más elevados y una asociación positiva con sRAGE.

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.

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.

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.

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.

Endogenous viral elements in mosquito genomes: current knowledge and outstanding questions.

Integrations from non-retroviral RNA viruses (nrEVEs) have been identified across several taxa, including mosquitoes. Amongst all Culicinae species, the viral vectors Aedes aegypti and Aedes albopictus stand out for their high number of nrEVEs. In addition, Aedes nrEVEs are enriched in piRNA clusters and generate piRNAs that can silence incoming viral genomes. As such, nrEVEs represent a new form of inherited antiviral immunity. To propel this discovery into novel transmission-blocking vector control strategies, a deeper understanding of nrEVE biology and evolution is essential because differences in the landscape of nrEVEs have been identified in wild-caught mosquitoes, the piRNA profile of nrEVEs is not homogeneous and nrEVEs outside piRNA clusters exist and are expressed at the mRNA level. Here we summarise current knowledge on nrEVEs in mosquitoes and we point out the many unanswered questions and potentials of these genomic elements.

Are traditional screening tools adequate for monitoring the nutrition risk of in-hospital patients? An analysis of the nutritionDay database.

BACKGROUND: Monitoring of adequate food intake is not a priority in hospital patients' care. The present study aimed to examine selective data from the nutritionDay survey to determine the impact of food intake during hospitalization on outcomes according to the nutrition risk status. METHODS: We conducted a descriptive analysis of selected data from 7 consecutive, annual, and cross-sectional nutritionDay samples from 2009 to 2015. The impact of food intake on outcomes was assessed by univariate and multivariate Cox models controlling for PANDORA scores. RESULTS: A total of 7994 adult patients from Colombia, 7243 patients from 9 Latin American countries, and 155,524 patients worldwid were included. Less than half of the patients worldwide consumed their entire meal on nutritionDay (41%). The number of reduced eaters is larger in the "no nutrition risk group" than in the "nutrition risk group" (30% vs 25%). Reduced eating is associated with higher mortality and delayed discharge in patients, regardless of the nutrition risk status. Patients without nutrition risk at the screening who ate "nothing, but were allowed to eat" had 6 times more risk of mortality (hazard ratio, 6.48; 95% CI, 3.5311.87). CONCLUSIONS: This is the first large-scale study evaluating the relationship of food intake on clinical outcomes showing an increase of in-hospital mortality rates and a reduction in the probability of being discharged home regardless of the nutrition risk status. Traditional screening tools may not identify a group of patients who will become at risk because of reduced intake while in the hospital.

RESUMEN OBJETIVO Determinar los factores relacionados con los costos generales durante la atención en salud de siniestros de tránsito en Bucaramanga, Colombia. MÉTODOS Estudio descriptivo, transversal, con análisis de registros de siniestros de tránsito durante 2019 en Bucaramanga, Colombia. Se realizó una comparación entre cuartiles de los costos en dólares con pruebas estadísticas de Chi-cuadrado de Pearson y exacta de Fisher. También, se calcularon odds ratio en regresión logística. RESULTADOS En 2019 se registraron 3.150 siniestros, con 7.038 personas involucradas, de los cuales 812 tenían información de costos generados por atención en instituciones de salud. La mediana de costos fue US$ 56,59 (RI = 29,35-140,15), promedio de US$ 290,11 ± 731,22 (IC95% 239,74-340,48). Se observó mayor posibilidad para estar en cuartil 4 de los costos si la persona tenía menos de 18 años (OR = 4,88; IC95% 1,30-18,32) o entre los 46-60 años de edad (OR = 3,66; IC95% 1,01-13,30), cuando el tipo de vehículo es la motocicleta (OR = 2,79; IC95% 1,25-6,24) y la bicicleta (OR = 7,66; IC95% 2,70-21,68), si la lesión ocurre en la cabeza (OR = 4,50; IC95% 2,61-7,76) y si la hipótesis está relacionada con embriaguez (OR = 12,44; IC95% 2,01-76,87). CONCLUSIÓN Los factores relevantes en los costos fueron la motocicleta, bicicleta, lesión en la cabeza, ser menor de 18 años o tener entre los 46 años y los 60 años y embriaguez como hipótesis. Es relevante implementar medidas de prevención según los factores identificados para disminuir la accidentalidad y, por ende, sus costos socioeconómicos.
