ABSTRACT

Introducción: La ecografía es una herramienta fundamental al momento de enfrentarse a un paciente grave en el servicio de urgencia. El protocolo "Focused Assessment with Sonography for Trauma" (FAST), es la utilización del ultrasonido en contexto de trauma, el cual está extensamente validado para medicina de urgencia de adultos. Sin embargo, en pediatría existen escasas publicaciones que resuman la evidencia relacionada. Objetivo: Dar a conocer la evidencia actualizada del uso de ecografía bajo el protocolo FAST en el trauma abdominal contuso pediátrico en el servicio de urgencia. De forma secundaria describir los pasos para realizar el examen e interpretación de sus hallazgos. Metodología: Revisión bibliográfica en las principales bases de datos, en idioma inglés o español, desde el año 2000 hasta la actualidad. Se seleccionaron estudios de rendimiento diagnóstico y revisiones narrativas relacionadas con el tratamiento y pronóstico del trauma general y abdominal en pediatría. Resultados: Se encontraron 998 artículos, de los cuales 22 fueron seleccionados y considerados para la revisión. La ecografía permite la identificación de líquido libre, que se relaciona con lesión intraabdominal en el contexto de trauma pediátrico. El protocolo FAST en el contexto de trauma contuso abdominal tiene una alta especificidad y una baja sensibilidad para su diagnóstico. El uso de ecografía en pediatría evita la exposición a los efectos dañinos de las radiaciones ionizantes. Conclusión: El uso de ecografía por parte de la medicina de urgencia se ha transformado en una herramienta esencial y segura al momento de evaluar pacientes. La presencia de un hallazgo positivo nos permite realizar diagnóstico de lesiones intraabdominales, pero un hallazgo negativo, no nos permite descartarlo, requiriendo exámenes complementarios.


Introduction: Ultrasound is an essential tool in diagnosing trauma in critical patients in the emergency room. The "Focused Assessment with Sonography for Trauma" (FAST) is the ultrasound protocol in the trauma context. It has been extensively validated for adult patients. However, few reviews have exposed and summarized the related evidence in pediatric emergency medicine. Objective: To present the FAST ultrasound protocol updated evidence in pediatric blunt abdominal trauma in the emergency department. Secondarily, to describe the steps to perform the examination and interpretation of their findings. Methodology: A bibliographical review was carried out in the main English or Spanish databases from 2000 to the present. Diagnostic studies and reviews of trauma treatment and prognosis in pediatrics were selected and summarized. Results: We found 998 articles, of which 22 were selected and screened for review. Ultrasound allows the identification of free fluid related to intra-abdominal injury in the context of pediatric trauma. Using ultrasound avoids children's exposure to the harmful effects of ionizing radiation. The FAST protocol in the context of blunt abdominal trauma has high specificity and low sensitivity for its diagnosis. Conclusion: The use of ultrasound in the field of emergency medicine has become an essential and safe tool. A positive finding allows us to diagnose intra-abdominal injuries, but a negative finding does not allow us to rule it out, requiring additional tests. The scientific evidence in the pediatric setting is more limited compared to adults.

ABSTRACT

Fundamentos: El aumento en la proporción de personas mayores genera eventos como disminución en la calidad de vida y deterioro físico, cuyas características son disminución demasa muscular y menor fuerza muscular. El objetivo del presente estudio es relacionar la fuerza prensil con diferentesvariables antropométricas, aportando datos cuantificables que contribuyan a reforzar la necesidad de intervención en la población de adultos mayores.Métodos: Estudio descriptivo de corte transversal (n = 84). Se identificaron variables sociodemográficas y antropométricas en personas mayores de 60 años residentes en establecimientos de larga estancia. Resultados: El 26,7% de los adultos mayores presenta malnutrición por exceso, mientras que el 20,2% y 32,9% de hombres y mujeres respectivamente, tienen masa muscular disminuida. Se observó una correlación positiva entre fuerza prensil y la circunferencia de pantorrilla y el IMC.Conclusiones: Existe una correlación entre la fuerza prensil y la masa muscular, lo que sugiere la necesidad urgente de generar programas preventivos en población mayor, integrando tanto la intervención nutricional, como kinésica, que en conjunto y bajo la mirada oportuna, permitiría mejorar la calidad de vida de las personas mayores.

Background: The increase in the proportion of older peoplegenerates events such as decreased quality of life and physicaldeterioration, whose characteristics are decreased muscle mass and reduced muscle strength. The objective of the present study was to relate prehensile strength with different anthropometric variables, providing quantifiable data that contribute to reinforce the need of intervention in the adult population.Methods: Descriptive cross-sectional study (n = 84). Sociodemographic and anthropometric variables were identified in people over 60 years old living in long-stay facilities. Results: Malnutrition due to excess was found in 26.7%, while 20.2% and 32.9% of men and women, respectively, had decreased muscle mass. A positive correlation is observed between prehensile strength with calf circumference and BMI. Conclusions: The existing correlation between prehensilestrength and muscle mass is confirmed, which suggests the urgent need to generate preventive programs in the elderly population, integrating both nutritional and kinesic interventions, which together and under the appropriate consideration, would allow to improve the quality of life of the elderly.

ABSTRACT

TAR DNA binding protein 43 kDa (TDP-43) is a ribonuclear protein regulating many aspects of RNA metabolism. Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Lobar Degeneration (FTLD) are fatal neurodegenerative diseases with the presence of TDP-43 aggregates in neuronal cells. Chaperone Mediated Autophagy (CMA) is a lysosomal degradation pathway participating in the proteostasis of several cytosolic proteins including neurodegenerative associated proteins. In addition, protein oligomers or aggregates can affect the status of CMA. In this work, we studied the relationship between CMA and the physiological and pathological forms of TDP-43. First, we found that recombinant TDP-43 was specifically degraded by rat liver's CMA+ lysosomes and that endogenous TDP-43 is localized in rat brain's CMA+ lysosomes, indicating that TDP-43 can be a CMA substrate in vivo. Next, by using a previously reported TDP-43 aggregation model, we have shown that wild-type and an aggregate-prone form of TDP-43 are detected in CMA+ lysosomes isolated from cell cultures. In addition, their protein levels increased in cells displaying CMA down-regulation, indicating that these two TDP-43 forms are CMA substrates in vitro. Finally, we observed that the aggregate-prone form of TDP-43 is able to interact with Hsc70, to co-localize with Lamp2A, and to up-regulate the levels of these molecular components of CMA. The latter was followed by an up-regulation of the CMA activity and lysosomal damage. Altogether our data shows that: (i) TDP-43 is a CMA substrate; (ii) CMA can contribute to control the turnover of physiological and pathological forms of TDP-43; and (iii) TDP-43 aggregation can affect CMA performance. Overall, this work contributes to understanding how a dysregulation between CMA and TDP-43 would participate in neuropathological mechanisms associated with TDP-43 aggregation.

ABSTRACT

La enuresis, definida como incontinencia urinaria durante el sueño desde los 5 años de edad, es una condición frecuente y estresante que puede llegar a tener un impacto profundo en la conducta, bienestar emocional y vida social del niño o adolescente. El objetivo del presente trabajo es realizar una revisión narrativa de la evidencia en relación a la evaluación y tratamiento de la enuresis. La evaluación inicial debe ir dirigida a diferenciar entre los pacientes con enuresis monosintomática y no-monosintomática, excluir condiciones no funcionales que pueden presentarse como enuresis y detectar problemas psicológicos. Para que la terapia sea exitosa, se debe desarrollar un plan de manejo que sea apropiado para el paciente y su contexto. En el subgrupo de enuresis no-monosintomática, el tratamiento de los síntomas diurnos es necesario antes de iniciar el manejo de la enuresis. Existen diversas alternativas de tratamiento para la enuresis, sin embargo, la terapia de alarma y la desmopresina poseen amplia evidencia para su empleo como primera línea. Palabras clave: Enuresis, Incontinencia Urinaria, Revisión, Sueño, Niños.


Enuresis, defined as urinary incontinence in children older than 5 years old, is a common and stressful condition that may cause deep consequences on the child or young person's behavior, emotional wellbeing and social life. The aim of this work is to make a narrative review of evidence on evaluation and treatment of enuresis. The initial assessment must differentiate between monosymptomatic and non-monosymptomatic enuresis, rule out non-functional conditions that can manifest as enuresis and detect psychological problems. In order to achieve a successful treatment, it is essential to develop a management plan according to the patient and its context. In non-monosymptomatic enuresis, it is necessary to treat daytime symptoms before management of bedwetting. There are many different therapeutic options for enuresis, nevertheless, alarm and desmopressin are evidence-based firstline treatments. Keywords: Enuresis, Urinary Incontinence, Review, Sleep, Child.
