Una aplicación móvil de ayuda para estudiantes de epidemiología: evaluación preliminar de EpiApp

Introducción: Las aplicaciones móviles (Apps) están transformando las perspectivas de aprendizaje en entornos de salud. Objetivo: Evaluar la efectividad y usabilidad de EpiApp como herramienta de apoyo en la consulta y resolución de problemas de epidemiología comparada con métodos tradicionales (MT). Materiales y métodos: Se diseñó EpiApp usando una estructura metodológica. Se realizó un estudio experimental controlado y aleatorizado con dos grupos: EpiApp y MT. La fectividad se evaluó con un cuestionario estandarizado y la usabilida con la escala MARS. Resultados: Se aleatorizaron 176 estudiantes: EpiApp (n=88) y MT (n=88). El tiempo de respuesta fue menor para los usuarios de EpiApp (23,99 min [± DE 8,38] vs. 29,16 min [± DE 11,61], p = 0,005). No hubo diferencias en el número de respuestas correctas (p = 0,635), ni en la oportunidad de aprobar el cuestionario (p = 0,054). La usabilidad fue buena (MARS > 4). Discusión: Las Apps móviles tienen un gran potencial para ser útiles en la educación en salud y en la toma de decisiones en epidemiología, así como en la atención médica en general. No obstante, es esencial realizar estudios rigurosos para garantizar que estas aplicaciones sean efectivas, útiles, fáciles de usar y comprender. Conclusiones: EpiApp redujo el tiempo de respuesta en la resolución de problemas de epidemiología sin afectar el número de respuestas correctas. La usabilidad fue buena, aunque hay oportunidad de mejora en diversión, interés, adaptabilidad individual e interactividad. La efectividad y usabilidad de EpiApp requiere ser validada con estudios más rigurosos y en diferentes contextos.

Introduction: Mobile applications (Apps) are transforming learning perspectives in healthcare settings. Objective: To evaluate the effectiveness and usability of EpiApp as a support tool in the consultation and resolution of epidemiology problems, compared to traditional methods (TM). Methodology: EpiApp was designed using a methodological structure. A randomized controlled experimental study was conducted with two groups: EpiApp and TM. A standardized questionnaire and the MARS scale were used to evaluate effectiveness and usability, respectively. Results: A total of 176 students were randomized: EpiApp (n=88) and TM (n=88). Response time was shorter for EpiApp users (23.99 min [±SD 8.38] vs. 29.16 min [±SD 11.61], p=0.005). There were no differences in the number of correct responses (p=0.635) or the opportunity to pass the questionnaire (p=0.054). Usability was good (MARS>4). Discussion: Mobile Apps have great potential to be useful in healthcare education and decision-making in epidemiology, as well as in general medical care. However, it is essential to conduct rigorous studies to ensure that these applications are effective, useful, and easy to use and understand. Conclusions: EpiApp reduced response time in solving epidemiology problems without affecting the number of correct answers. The usability was good, although there is room for improvement in terms of enjoyment, interest, individual adaptability, and interactivity. The effectiveness and usability of EpiApp need to be validated through more rigorous studies in different contexts.

Hallazgo incidental de neoplasia primaria de pulmón: blastoma pulmonar en mujer adulta. Reporte de caso / Incidental finding of primary lung neoplasm: pulmonary blastoma in an adult woman, case report

El blastoma pulmonar es una neoplasia poco común y agresiva que se origina en el pulmón; está compuesto por tejido mesenquimal y epitelial inmaduro que imita la configuración pulmonar en etapas embrionarias. Tiene una baja incidencia y una alta tasa de mortalidad, con aproximadamente un 60 %. Este blastoma tiende a desarrollarse con mayor frecuencia entre la cuarta y quinta década de vida, siendo más prevalente en mujeres y generalmente asociado al tabaquismo. Se presenta el caso de una mujer de 23 años sin factores de riesgo conocidos, a quien se le diagnosticó incidentalmente un blastoma pulmonar primario. La paciente experimentaba dolor en la región costal izquierda, tos productiva, disnea y hemoptisis desde hace 30 días. Los hallazgos en las imágenes de rayos X y tomografías de tórax llevaron a la realización de una biopsia del pulmón izquierdo, que reveló fragmentos de tejido con una notable presencia de necrosis tumoral. Cinco días después, la paciente consultó nuevamente debido a un empeoramiento de los síntomas, incluyendo dolor torácico de tipo pleurítico. Se decidió realizar una lobectomía inferior izquierda, durante la cual se encontró un tumor sólido adherido a la pleura visceral, con masas tumorales en la pleura parietal. El estudio histopatológico final confirmó el diagnóstico de un tumor maligno de alto grado compatible con blastoma pulmonar. En conclusión, el blastoma pulmonar es una neoplasia rara que puede presentarse en diferentes etapas de la vida, aunque tiene mayor incidencia entre los 40 y 50 años. Es importante que los patólogos consideren esta enfermedad en sus diagnósticos diferenciales debido a los desafíos que implica su diagnóstico. Detectar el blastoma pulmonar en etapas tempranas es crucial para el tratamiento adecuado, aunque actualmente no se conocen marcadores predictivos confiables y el pronóstico de esta enfermedad es generalmente desfavorable.

Pulmonary blastoma is a rare and aggressive neoplasm that originates in the lung. It is composed of immature mesenchymal and epithelial tissue that mimics the embryonic configuration of the lung. It has a low incidence and a high mortality rate, of approximately 60%. Pulmonary blastoma tends to occur more frequently between the fourth and fifth decades of life, being more prevalent in women and generally associated with smoking. The case of a 23-year-old woman with no known risk factors is presented, who incidentally was diagnosed with a primary pulmonary blastoma. The patient experienced pain in the left costal region, productive cough, dyspnea, and hemoptysis for 30 days. Findings on X-ray and chest tomography led to a biopsy of the left lung, which revealed tissue fragments with significant tumor necrosis. Five days later, the patient consulted again due to worsened symptoms, including pleuritic chest pain. It was decided to perform a left lower lobectomy, during which a solid tumor attached to the visceral pleura with tumor masses in the parietal pleura was found. The final histopathological study confirmed the diagnosis of a high-grade malignant tumor compatible with pulmonary blastoma. In conclusion, pulmonary blastoma is a rare neoplasm that can occur at different stages of life, although it has a higher incidence between the ages of 40 and 50. Pathologists need to consider this disease in their differential diagnoses due to the challenges involved in its diagnosis. Detecting pulmonary blastoma at early stages is crucial for appropriate treatment, although currently there are no reliable predictive markers, and the prognosis of this disease is generally unfavorable.

Brazilian Society of Otology task force - Otosclerosis: evaluation and treatment

Abstract Objectives: To review and provide evidence-based recommendations for the diagnosis and treatment of otosclerosis. Methods: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on otosclerosis were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. Results: The topics were divided into 2 parts: 1) Diagnosis - audiologic and radiologic; 2) Treatment - hearing AIDS, pharmacological therapy, stapes surgery, and implantable devices - bone-anchored devices, active middle ear implants, and Cochlear Implants (CI). Conclusions: The pathophysiology of otosclerosis has not yet been fully elucidated, but environmental factors and unidentified genes are likely to play a significant role in it. Women with otosclerosis are not at increased risk of worsening clinical condition due to the use of contraceptives or during pregnancy. Drug treatment has shown little benefit. If the patient does not want to undergo stapedotomy, the use of hearing aids is well indicated. Implantable systems should be indicated only in rare cases, and the CI should be indicated in cases of profound deafness.

Factores asociados al tratamiento no exitoso para tuberculosis en pacientes previamente tratados en Cali, Colombia, en el periodo 2015-2019 / Factors associated with unsuccessful treatment outcome for tuberculosis in previously treated patients in Cali, Colombia, during the period 2015-2019

Introducción. Las tasas de éxito del tratamiento de la tuberculosis continúan siendo subóptimas. Objetivo. Identificar los factores asociados al tratamiento no exitoso para tuberculosis en pacientes con antecedentes de tratamiento para la tuberculosis. Materiales y métodos. Se realizó un estudio observacional retrospectivo, analítico, de cohorte de pacientes que reingresaron a un programa de micobacterias en Cali, Colombia. Se incluyeron mayores de 15 años con tuberculosis pulmonar entre el 2015 y el 2019 con antecedentes de tratamiento para la tuberculosis. Se excluyeron los pacientes con tuberculosis resistente. Resultados. Ingresaron 605 pacientes con antecedentes de tratamiento, 60 % por tratamiento inconcluso y 40 % por recaída. En comparación con los pacientes que reingresaron por recaída (ORa= 2,34; IC=1,62-3,38), las variables que explicaron de manera independiente el no tener éxito con el tratamiento para la tuberculosis al egreso fueron: estar en situación de calle (ORa = 2,45; IC = 1,54-3,89), ser farmacodependiente (ORa = 1,95; IC=1,24-3,05), tener coinfección tuberculosis/VIH (ORa = 1,69; IC =1,00- 2,86) o diabetes (ORa =1,89; IC=1,29-2,77), y el incumplimiento de un tratamiento previo por pérdida de seguimiento, abandono u otras causas. Las variables programáticas que favorecieron el éxito del tratamiento fueron la asesoría de la prueba voluntaria de VIH (p < 0,001) y la realización de la prueba de VIH (p < 0,001). Conclusión. Estar en situación de calle, ser farmacodependiente, tener coinfección de tuberculosis y VIH, o diabetes, así como el incumplimiento del tratamiento previo por pérdida del seguimiento, abandono o fracaso del mismo, dificultaron el éxito del tratamiento antituberculoso. En la primera atención al reingreso de los pacientes con tuberculosis se deben identificar y abordar estas características.

Introduction. The success rates in the treatment of tuberculosis are suboptimal. Objective. To identify associated factors with the lack of success of antituberculosis treatment in patients with a tuberculosis treatment history. Materials and methods. We performed a retrospective, analytical, observational, and cohort study of patients reentering the Mycobacterium program in Cali, Colombia. We included patients over 15 years old with pulmonary tuberculosis between 2015 and 2019 and a history of tuberculosis treatment. Patients with drug-resistant tuberculosis were excluded. Results. A total of 605 patients with a treatment history were included, 60% due to unfinished treatment and 40% due to relapse. Compared to patients reentering due to relapse (ORa=2.34, CI=1.62-3.38), the independent variables associated with treatment failure at discharge were homelessness (ORa=2.45, CI=1.54-3.89), substance dependence (ORa=1.95, CI=1.24-3.05), tuberculosis/HIV coinfection (ORa=1.69, CI=1.00-2.86), diabetes (ORa=1.89, CI=1.29-2.77), and unfinished previous tuberculosis treatment due to follow-up loss, abandonment, or other causes. Programmatic variables favoring treatment success were voluntary HIV testing counseling (p<0.001) and HIV testing (p<0.001). Conclusion. Homelessness, substance dependence, tuberculosis/HIV coinfection, diabetes, and incomplete previous treatment due to loss to follow-up, abandonment, or treatment failure hindered the success of antituberculosis. These characteristics should be identified and addressed during the initial care of patients reentering treatment for tuberculosis.

Consenso colombiano de la enfermedad inflamatoria intestinal pediátrica

está disponible en el texto completo

Introduction: Pediatric ulcerative colitis (CUP), pediatric Crohn's disease (PCD), and pediatric inflammatory bowel disease not classifiable (PIDNCID) have clinical and psychosocial particularities that differentiate them from those of adults and may condition different therapeutic approaches due to possible nutritional, growth and developmental repercussions, representing a challenge for the pediatrician and gastroenterologist. Objective: Develop expert consensus evidence-based recommendations for the timely and safe diagnosis and treatment of Pediatric Inflammatory Bowel Disease (PID) in children under 18 years of age for professionals caring for these patients and healthcare payers. Methodology: Through a panel of experts from the Colombian College of Pediatric Gastroenterology, Hepatology and Nutrition (COLGAHNP) and a multidisciplinary group, 35 questions were asked regarding the clinical picture, diagnosis, and treatment of PID. Through a critical review and analysis of the literature with particular emphasis on the main clinical practice guidelines (CPGs), randomized clinical trials (RCTs), and meta-analyses of the last ten years, from which the experts made 77 recommendations that responded to each of the research questions with their respective practical points. Subsequently, each of the statements was voted on within the developer group, including the statements that achieved > 80%. Results: All statements scored > 80%. PID has greater extension, severity, and evolution towards stenosis, perianal disease, extraintestinal manifestations, and growth retardation compared to adult patients, so its management should be performed by multidisciplinary groups led by pediatric gastroenterologists and prepare them for a transition to adulthood. Porto's criteria allow a practical classification of PID. In CPE, we should use the Paris classification and perform ileocolonoscopy and esophagogastroduodenoscopy, since 50% have upper involvement, using the SES-CD (UCEIS/Mayo in CUP) and taking multiple biopsies. Initial labs should include inflammatory markers and fecal calprotectin and rule out intestinal infections. Treatment, induction, and maintenance of PID should be individualized and decided according to risk stratification. Follow-up should use PCDAI and PUCAI for the last 48 hours. Immunologists and geneticists should evaluate patients with early and infantile PID. Conclusion: A consensus guideline is provided with evidence-based recommendations on timely and safe diagnosis and treatments in patients with ILD.

Aspectos clínico-epidemiológicos en pacientes con abscesos odontogénicos cervicofaciales y factores asociados para estancia hospitalaria corta / Clinical-epidemiological aspects in patients with cervicofacial odontogenic abscesses and associated factors for short hospital stay

Introducción: en todo paciente hospitalizado con absceso odontogénico cervicofacial se busca resolución pronta del absceso, pero es necesario conocer cuáles son los factores que favorecen la resolución en hospitalizaciones cortas (1-3 días). Objetivo: determinar factores clínico-epidemiológicos de pacientes con abscesos odontogénicos para identificar factores que correlacionan con hospitalización corta. Material y métodos: estudio transversal, retrospectivo, observacional y analítico de 100 pacientes con abscesos odontogénicos en un Hospital General de Zona del Instituto Mexicano del Seguro Social de los años 2012-2013. Variables de estudio: días de hospitalización, sexo, edad, comorbilidades, conteo leucocitario, trismus, diente causal, región afectada y tratamientos realizados. Tamaño de muestra obtenido con fórmula para estudios observaciones con manejo de prevalencias para poblaciones infinitas, se empleó χ2 para identificar factores que correlacionan con hospitalización corta. Resultados: mujeres 56%, rango de edad 12-89 años y de hospitalización de 1-23 días; con comorbilidades 56%, leucocitosis 39% y trismus 21%. La caries causó 64% de abscesos, molares inferiores 70% y región submandibular afectada 73%. Variables estadísticamente significativas; conteo leucocitario, diente causal y región afectada. Conclusión: factores correlacionados con hospitalización corta: conteo leucocitario menor a 10,500 leucocitos, que el molar inferior no sea el diente causal y que la región submandibular no esté afectada (AU)

Introduction: prompt resolution of the abscess is sought in all patients hospitalized with cervicofacial odontogenic abscess, but which factors favor this resolution in short hospitalizations (1-3 days). Objective: determine clinical-epidemiological factors of patients with odontogenic abscesses to identify factors that correlate with short hospitalization. Material and methods: crosssectional, retrospective, observational and analytical study of 100 patients with odontogenic abscesses in a General Hospital of the Zone of the Mexican Social Security Institute from 2012-2013. Study variables; days of hospitalization, sex, age, comorbidities, leukocyte count, trismus, causative tooth, affected region and treatments performed.

Results: women 56%, age range 12-89 years and hospitalization of 1-23 days, with comorbidities 56%, leukocytosis 39% and trismus 21%. Caries caused 64% of abscesses, lower molars 70% and affected submandibular region 73%. Statistically significant variables; leukocyte count, causative tooth and affected region. Conclusion: factors correlated with short hospitalization; leukocyte count less than 10,500 leukocytes, that the lower molar is not the causal tooth and that the submandibular region is not affected.

Aprendizaje automático aplicado a la predicción de diabetes mellitus, utilizando información socioeconómica y ambiental de usuarios del sistema de salud

Objetivo: Se propuso aplicar modelos basados en técnicas de aprendizaje automático como apoyo para el diagnóstico temprano de la diabetes mellitus, utilizando variables de datos ambientales, sociales, económicos y sanitarios, sin la dependencia de la toma de muestras clínicas. Metodología: Se utilizaron datos de 10 889 usuarios afiliados al régimen subsidiado de salud de la zona suroccidental en Colombia, diagnosticados con hipertensión y agrupados en usuarios sin (74,3 %) y con (25,7 %) diabetes mellitus. Se entrenaron modelos supervisados utilizando k vecinos más cercanos, árboles de decisión y bosques aleatorios, así como modelos basados en ensambles, aplicados a la base de datos antes y después de balancear el número de casos en cada grupo de diagnóstico. Se evalúo el rendimiento de los algoritmos mediante la división de la base de datos en datos de entreno y de prueba (70/30, respectivamente), y se utilizaron métricas de exactitud, sensibilidad, especificidad y área bajo la curva. Resultados: Los valores de sensibilidad aumentaron considerablemente al utilizar datos balanceados, pasando de valores máximos del 17,1 % (datos sin balancear) a valores de hasta 57,4 % (datos balanceados). El valor más alto de área bajo la curva (0,61) fue obtenido con los modelos de ensambles, al aplicar un balance en el número de datos por cada grupo y al codificar las variables categóricas. Las variables de mayor peso estuvieron asociadas con aspectos hereditarios (24,65 %) y con el grupo étnico (5.59 %), además de la dificultad visual, el bajo consumo de agua, una dieta baja en frutas y verduras, y el consumo de sal y azúcar. Conclusiones: Aunque los modelos predictivos, utilizando información socioeconómica y ambiental de las personas, surgen como una herramienta para el diagnóstico temprano de la diabetes mellitus, estos aún deben ser mejorados en su capacidad predictiva.

Objective: The objective was to apply models based on machine learning techniques to support the early diagnosis of diabetes mellitus, using environmental, social, economic and health data variables, without dependence on clinical sample collection. Methodology: Data from 10,889 users affiliated with the subsidized health system in the southwestern area of Colombia, diagnosed with hypertension and grouped into users without (74.3%) and with (25.7%) diabetes mellitus, were used. Supervised models were trained using k-nearest neighbors, decision trees, and random forests, as well as ensemble-based models, applied to the database before and after balancing the number of cases in each diagnostic group. The performance of the algorithms was evaluated by dividing the database into training and test data (70/30, respectively), and metrics of accuracy, sensitivity, specificity, and area under the curve were used. Results: Sensitivity values increased significantly when using balanced data, going from maximum values of 17.1% (unbalanced data) to values as high as 57.4% (balanced data). The highest value of area under the curve (0.61) was obtained with the ensemble models, by applying a balance in the amount of data for each group and by coding the categorical variables. The variables with the greatest weight were associated with hereditary aspects (24.65%) and with the ethnic group (5.59%), in addition to visual difficulty, low water consumption, a diet low in fruits and vegetables, and the consumption of salt and sugar. Conclusions: Although predictive models, using people's socioeconomic and environmental information, emerge as a tool for the early diagnosis of diabetes mellitus, their predictive capacity still needs to be improved.

Objetivo: Propôs-se aplicar modelos baseados em técnicas de aprendizagem automática como apoio para o diagnóstico precoce da diabetes mellitus, utilizando variáveis de dados ambientais, sociais, econômicos e sanitários, sem a dependência da coleta de amostras clínicas. Metodologia: Usaram-se dados de 10.889 usuários filiados ao regime subsidiado de saúde da zona sudoeste da Colômbia, diagnosticados com hipertensão e agrupados em usuários sem (74,3%) e com (25,7%) diabetes mellitus. Foram treinados modelos supervisionados utilizando k vizinhos mais próximos, árvores de decisão e florestas aleatórias, assim como modelos baseados em montagens, aplicados à base de dados antes de depois de equilibrar o número de casos em cada grupo de diagnóstico. Avaliou-se o desempenho dos algoritmos por meio da divisão da base de dados de treino e teste (70/30, respectivamente), e utilizaram-se métricas de exatidão, sensibilidade, especificidade e área sob a curva. Resultados: Os valores de sensibilidade aumentaram de maneira significativa ao utilizar dados equilibrados, passando de valores máximos de 17,1% (dados sem equilibrar) a valores de até 57,4% (dados equilibrados). O valor mais elevado de área sob a curva (0,61) foi obtido com os modelos de montagens, ao aplicar um balanço no número de dados por cada grupo e codificar as variáveis categóricas. As variáveis de maior peso estiveram associadas com fatores hereditários (24,65%) e com o grupo étnico (5,59%), além da dificuldade visual, o baixo consumo de água, um regime baixo em frutas e vegetais e o consumo de sal e açúcar. Conclusões: Embora os modelos preditivos, utilizando informação socioeconômica e ambiental das pessoas, surgem como uma ferramenta para o diagnóstico precoce da diabetes mellitus, ainda devem ser melhorados em sua capacidade preditiva.

Abstract Objective: To review the literature on the diagnosis and treatment of vestibular schwannoma. Methods: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on vestibular schwannoma were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. Results: The topics were divided into 2 parts: (1) Diagnosis - audiologic, electrophysiologic tests, and imaging; (2) Treatment - wait and scan protocols, surgery, radiosurgery/radiotherapy, and systemic therapy. Conclusions: Decision making in VS treatment has become more challenging. MRI can diagnose increasingly smaller tumors, which has disastrous consequences for the patients and their families. It is important to develop an individualized approach for each case, which highly depends on the experience of each surgical team.

Teratoma de ligamento redondo, reporte de caso y revisión de la bibliografía / Round ligament teratoma, case report and literature review

Resumen ANTECEDENTES: El teratoma es un tumor casi siempre benigno, con una amplia variabilidad en su localización, extremadamente rara, en el ligamento redondo. CASO CLÍNICO: Paciente de 30 años, con antecedente de un embarazo a término. En la revisión ecográfica se reportó una lesión quística paraovárica izquierda de 46 x 35 mm, sin componente sólido, graso ni calcificaciones. En el examen ginecológico se palpó una masa por encima del útero, orientada hacia el lado izquierdo, no dolorosa. El resto del examen físico trascurrió sin otras alteraciones. La impresión diagnóstica inicial fue de teratoma abdominopélvico sustentada en la ecografía transvaginal en la que los ovarios se observaron normales, con una masa de ecogenicidad mixta de 50 x 40 x 46 mm, con áreas ecolúcidas y ecogénicas de intensidad variable hacia la fosa iliaca izquierda superior, sin contacto con el ovario. El ligamento redondo se seccionó a ambos lados de la masa y se extrajo sin complicaciones; el reporte histopatológico fue de: teratoma quístico maduro. CONCLUSIONES: El ligamento redondo es una localización infrecuente de los quistes dermoides que debe considerarse en los diagnósticos diferenciales de las masas pélvicas; es susceptible de tratamiento quirúrgico por vía laparoscópica.

Abstract BACKGROUND: Teratoma is an almost always benign tumor, with a wide variability in its location; its location in the round ligament is extremely rare. CLINICAL CASE: 30-year-old patient, with a history of a full-term pregnancy. On routine ultrasound examination, a 46 x 35 mm left paraovarian cystic lesion was reported, with no solid, fatty component or calcifications. In the gynecological examination a mass was palpated above the uterus, oriented to the left side, non-painful. The rest of the physical examination passed without other alterations. The initial diagnostic impression was of abdomino-pelvic teratoma supported by transvaginal ultrasound in which the ovaries were normal, with a mass of mixed echogenicity of 50 x 40 x 46 mm, with echolucent and echogenic areas of variable intensity towards the left superior iliac fossa, without contact with the ovary. The round ligament was sectioned on both sides of the mass and removed without complications; the histopathologic report was: mature cystic teratoma. CONCLUSIONS: The round ligament is an infrequent location of dermoid cysts that should be considered in the differential diagnoses of pelvic masses; it is amenable to surgical treatment laparoscopically.

The significance level adopted was p<0.05. The results revealed that there was a significant increase in sleep duration on weekdays for girls (p=0.001) and boys (p=0.001) and in screen time during the pandemic for girls (p=0.028) and boys (p= 0.004). There was a decrease in the level of physical activity of girls (p=0.025). It is concluded that, among the students at this Federal Institute, the COVID-19 pandemic increased the sleep duration and screen time of male and female adolescents and decreased the level of physical activity of girls.

Mechanical power measurement during mechanical ventilation of SARS-CoV-2 critically ill patients. A cohort study / Medición del poder mecánico durante ventilación mecánica en pacientes críticamente enfermos con SARS-CoV-2, Estudio de cohorte

Abstract Introduction: The ventilator-induced lung injury (VILI) depends on the amount of energy per minute transferred by the ventilator to the lung measured in Joules, which is called mechanical power. Mechanical power is a development variable probably associated with outcomes in ventilated patients. Objective: To describe the value of mechanical power in patients with SARS-CoV-2 infection and ventilated for other causes and its relationship between days of mechanical ventilation, length of stay in the intensive care unit (ICU), and mortality. Methods: A multicenter, analytical, observational cohort study was conducted in patients with SARS-CoV-2 infection who required invasive mechanical ventilation and patients ventilated for other causes for more than 24 hours. Results: The cohort included 91 patients on mechanical ventilation in three tertiary care centers in the city of Pereira, Colombia. The average value of the mechanical power found was 22.7 ± 1 Joules/ min. In the subgroup of patients with SARS-CoV-2 infection, the value of mechanical power was higher 26.8 ± 9 than in the subgroup of patients without a diagnosis of SARS-CoV-2 infection 18.2 ± 1 (p <0.001). Conclusions: Mechanical power is an important variable to consider during the monitoring of mechanical ventilation. This study found an average value of mechanical power of 22.7 ± 1 Joules/min, being higher in patients with SARS-CoV-2 infection related to longer days of mechanical ventilation and a longer stay in the ICU.

Resumen Introducción: La lesión pulmonar inducida por la ventilación mecánica (LPIVM) depende, entre otras variables, de la cantidad de energía -medida en Joules- por unidad de tiempo transferida desde el ventilador al paciente, también llamada poder mecánico. El poder mecánico es una variable de desarrollo, posiblemente asociada a los desenlaces en pacientes sometidos a ventilación. Objetivo: Describir el valor del poder mecánico en pacientes con infección por SARS-CoV-2 y ventilados por otras causas y la relación entre días de ventilación mecánica, estancia en la UCI y mortalidad. Métodos: Estudio multicéntrico, analítico y observacional de cohorte realizado en pacientes con diagnóstico de infección por SARS-CoV-2 que requirieron soporte ventilatorio mecánico invasivo y pacientes ventilados por otras causas, durante más de 24 horas. Resultados: La cohorte incluyó 91 pacientes que recibieron ventilación mecánica en 3 centros de tercer nivel de la ciudad de Pereira, Colombia. El valor promedio del poder mecánico obtenido fue 22,7 ± 1 Joules/min. En el grupo de pacientes con infección por SARS-CoV-2 el valor obtenido fue mayor (26,8 ± 9), comparado con el grupo de pacientes sin infección por SARS-CoV-2 (18,2 ± 1) (p <0,001). Conclusiones: El poder mecánico es una variable importante a tener en cuenta en el monitoreo de la ventilación mecánica. El presente estudio encontró un valor promedio de poder mecánico de 22,7±1 Joules/min, siendo mayor en los pacientes con infección por SARS-CoV-2 en relación con más días de ventilación mecánica y estancia en UCI más prolongada.
