Perfil de prescripción de levetiracetam en niños menores de cuatro años atendidos en un hospital de alta complejidad de Chile / Levetiracetam prescription profile in children younger than 4 years treated at a tertiary care hospital in Chile

Introducción. El levetiracetam (LEV) es un antiepiléptico aprobado por el Instituto de Salud Pública de Chile como terapia concomitante en crisis epilépticas en niños mayores de cuatro años. Sin embargo, es ampliamente indicado desde el periodo neonatal, lo que hace necesario evaluar su utilización fuera de ficha técnica. Objetivo. Determinar el perfil de prescripción-indicación de LEV en el tratamiento de las crisis epilépticas en menores de cuatro años en un hospital de alta complejidad del sur de Chile. Población y método. Estudio observacional, descriptivo y retrospectivo. Se revisaron las historias clínicas de quienes iniciaron tratamiento con LEV entre 2014 y 2019, y se recopilaron datos sobre variables sociodemográficas, farmacológicas y clínicas. El análisis se basó en la descripción del perfil de los pacientes, prescripción, seguimiento y seguridad. Resultados. Se incluyeron 68 pacientes: 40 (58,8 %) de sexo masculino, 49 (72,1 %) con edad gestacional ≥ 37 semanas. La etiología principal de la epilepsia fue de tipo estructural (35,3 %); el LEV se utilizó principalmente en niños diagnosticados con malformación del sistema nervioso central (17,6 %) y predominó la monoterapia (55,9 %). En el 50 % se usó LEV para crisis focales. Cinco niños (7,3 %) presentaron trastornos de tipo psiquiátrico clasificados como probables reacciones adversas al medicamento. Conclusión. El LEV se utilizó en niños con diferentes diagnósticos con baja frecuencia de eventos adversos. El perfil de utilización varió en los diferentes grupos etarios. Es necesario identificar en futuros estudios la efectividad especialmente en el recién nacido y en epilepsias refractarias.

Introduction. Levetiracetam (LEV) is an antiepileptic drug approved by the Chilean Institute of Public Health as concomitant therapy for epileptic seizures in children older than 4 years of age. However, it is widely prescribed from the neonatal period, which makes it necessary to evaluate its off-label use. Objective. To determine the prescription-indication profile of LEV in the treatment of epileptic seizures in children younger than 4 years in a tertiary care hospital in southern Chile. Population and method. Observational, descriptive, and retrospective study. The medical records of patients who started treatment with LEV between 2014 and 2019 were reviewed, and data on sociodemographic, pharmacological, and clinical variables were collected. The analysis was based on the description of the profile of patients, prescriptions, follow-up, and safety. Results. A total of 68 patients were included: 40 (58.8%) were males, 49 (72.1%) were born at a gestational age ≥ 37 weeks. The main etiology of epilepsy was structural (35.3%); LEV was mostly used in children diagnosed with central nervous system malformation (17.6%), and monotherapy was the prevailing dosage (55.9%). LEV was used for focal seizures in 50% of cases. Five children (7.3%) had psychiatric disorders, classified as probable adverse drug reactions. Conclusion. LEV was used in children with various diagnoses, with a low rate of adverse events. The profile of drug use varied in the different age groups. Future studies are needed to identify effectiveness, especially in newborn infants and patients with refractory epilepsy.

Efectos de las Técnicas de Cierre de Fisura Labio-Máxilo-Palatina sobre el Crecimiento y Desarrollo Esqueletal: Una Revisión Narrativa

Las fisuras labio-máxilo-palatinas (FLMP) son malformaciones congénitas que requieren de un manejo quirúrgico complejo para devolver un correcto funcionamiento del sistema estomatognático. Sin embargo, aún no existe un consenso sobre qué modalidad quirúrgica representa los mejores resultados y sus efectos a largo plazo en el desarrollo esqueletal y funcional de los individuos. El objetivo de este trabajo fue describir mediante la información científica disponible; el efecto de los diferentes protocolos quirúrgicos para el cierre de la FLMP sobre el crecimiento y desarrollo esqueletal de los pacientes. Se realizó una búsqueda de la literatura en bases de datos Pubmed, Cochrane y Epistemonikos, contemplando estudios desde el año 2013 hasta la actualidad. Se obtuvieron un total de 999 estudios encontrados. Una vez aplicados los criterios de inclusión y exclusión, se seleccionaron 13 estudios. El tratamiento quirúrgico de las FLMP consiste en procedimientos complejos que implican alteraciones en el desarrollo esqueletal de los individuos intervenidos a largo plazo. Las discrepancias en el desarrollo esqueletal de los pacientes empiezan a detectarse durante la dentición mixta. Es recomendable extender el seguimiento hasta la etapa de la pubertad y adultez, ya que podría demostrar diferencias significativas entre las diferentes cronologías quirúrgicas empleadas.

Cleft Lip and Palate (CLP) belong to a group of congenital anomalies that require complex surgical management, in order to restore the normal function of the stomatognathic system. However, there is no consensus that determines which surgical technique is better according to its outcomes and long- term effects on the skeletal and functional development of treated individuals. The objectives of this study are To describe, using the available scientific information, the effect of the different surgical protocols regarding CLP closure, on the skeletal and functional development patients undergoing surgery. A research of the available information was made in three different databases: PubMed, Cochrane and Epistemonikos. This research included articles released since the year 2013 onwards. A total of 999 studies were found. Once exclusion and inclusion criteria were applied, 13 studies were selected. Surgical treatment of CLP consists of complex procedures which imply long-term skeletal alterations in undergoing patients. These skeletal discrepancies are first detected during the mixed dentition phase. It is recommended to extend patient follow-up up until puberty and adulthood, as it might demonstrate significant differences among the different surgical approaches.

Topical agents for the prevention ofradiodermatitis in cancer patients: A systematic review / Agentes tópicos para prevenção de radiodermatiteem pacientes com câncer: revisão sistemática

Objetivo: Analisar as evidências sobre o efeito dos agentes tópicos empregados para a prevenção da radiodermatite em pacientes com câncer. Método: Revisão sistemática de estudos clínicos randomizados duplos-cegos construída conforme recomendações do Joanna Briggs Institute e busca nas bases de dados MEDLINE/PubMed, CINAHL, LILACS, Web of Science, Embase, Scopus, além da literatura cinzenta. Utilizaram-se a ferramenta de avaliação crítica do JBI para ensaios clínicos randomizados para avaliar a possibilidade de viés, o Grading of Recommendations, Assessment, Development and Evaluation para a qualidade das evidências e o Gradepro® para recomendá-las. Resultados: Selecionaram-se 13 estudos que avaliaram diferentes agentes tópicos para prevenir a radiodermatite, a saber: corticosteroides, de ação antioxidante e fitoterápicos. A qualidade metodológica de cada estudo foi apropriada, mas a qualidade da evidência gerada pela reunião deles foi baixa, independentemente do tipo de agente tópico empregado, sugerindo que a confiança no seu efeito é limitada e tornando a força de recomendação fraca. Conclusão: Alguns agentes tópicos mostraram-se promissores para a prevenção de radiodermatite, mas as evidências aqui reunidas sobre a eficácia deles não permitem indicar seu uso para a prevenção de radiodermatite em pacientes com câncer. (AU)

Objective: To analyze the evidence on the effect of topical agents to prevent radiodermatitis in cancer patients. Methods: Systematic review of double-blind randomized clinical studies built according to JBI recommendations and search in the databases MEDLINE/PubMed, CINAHL, LILACS, Web of Science, Embase and Scopus, in addition to the Gray Literature. The JBI critical assessment tool for randomized clinical trials was used to assess the possibility of bias, GRADE for the quality of evidence, and Gradepro® to recommend them. Results: Thirteen studies were selected that evaluated different topical agents to prevent radiodermatitis, namely: corticosteroids, with antioxidant action and herbal medicines. The methodological quality of each study was appropriate. Still, the quality of evidence generated by pooling them was low, regardless of the type of topical agent employed, suggesting that confidence in its effect is limited and weakening the strength of the recommendation. Conclusions: Some topical agents have shown promise for the prevention of radiodermatitis, but the evidence gathered here about their effectiveness does not indicate their use for the prevention of radiodermatitis in cancer patients. (AU)

Objetivo: Analizar la evidencia sobre el efecto de los agentes tópicos utilizados para la prevención de la radiodermatitis en pacientes con cáncer. Método: Revisión sistemática de estudios clínicos aleatorizados, doble ciego, elaborados según las recomendaciones del JBI y buscados en MEDLINE/PubMed, CINAHL, LILACS, Web of Science, Embase y Scopus, además de literatura gris. Se utilizó la herramienta de evaluación crítica JBI para ensayos clínicos aleatorios para evaluar la posibilidad de sesgo, GRADE para la calidad de la evidencia y Gradepro® para recomendarla. Resultados: Se seleccionaron trece estudios que evaluaron diferentes agentes tópicos para prevenir la radiodermatitis, a saber: corticosteroides, con acción antioxidante y fitoterapia. La calidad metodológica de cada estudio fue apropiada, pero la calidad de la evidencia generada al combinarlos fue baja, independientemente del tipo de agente tópico empleado, lo que sugiere que la confianza en su efecto es limitada y debilita la fuerza de la recomendación. Conclusión: Algunos agentes tópicos se han mostrado prometedores para la prevención de la radiodermatitis, pero la evidencia aquí reunida sobre su eficacia no nos permite indicar su uso para la prevención de la radiodermatitis en pacientes con cáncer.

Association between hyperglycemia and post-exodontia complications in patients with type ii diabetes mellitus: a scoping review / Asociación entre hiperglucemia y complicaciones post-exodoncia en pacientes con diabetes mellitus tipo ii: scoping review

Introduction: Diabetes mellitus (DM) is a prevalent chronic metabolic disorder worldwide, with Type II DM (T2DM) emerging as the most widespread variant. In Chile, approximately 11% of adults aged 20 to 79 suffer from this condition. Given its high prevalence, dental surgeons should be trained to evaluate risk factors, particularly the potential complications linked to tooth extraction in individuals with T2DM. Objetive: To describe the available scientific evidence on post-exodontia complications associated with hyperglycemia in patients with Type II diabetes mellitus. Materials and Methods: An exploratory systematic review was conducted following the PRISMA-ScR extension protocols using the databases PubMed, EBSCO, Scopus and the Cochrane Library. The search employed the following algorithms: (("Diabetic patient complications" AND "Dental extractions")), (("Diabetes" AND "tooth extraction")), (("Glycemia" AND "Tooth extraction complications"), (("Blood glucose" AND "Tooth extractions"), (("Dental extraction sockets" AND "Diabetics"). Results: Out of a total of 973 articles, 25 were included for this review. Six relevance criteria were considered, revealing safety parameters for conducting extractions in patients with T2DM, with capillary blood glucose levels not exceeding 200 mg/dL for elective extractions and 240 mg/dL for emergency extractions. Conclusions: There is limited evidence correlating threshold values of hyperglycemia with post-extraction complications in patients with T2DM. Most authors agree that the primary concern is not T2DM itself, but hyperglycemia. Furthermore, there is minimal consistency in the recommended care protocols for these patients.

Introducción: La diabetes mellitus (DM) es un trastorno metabólico crónico. A nivel mundial, la DM tipo II (DM2) resulta ser la más frecuente. En Chile, un 11% de la población adulta entre los 20 y 79 años la padece. Su alta prevalencia, requiere de un cirujano dentista preparado para valorar los factores de riesgo, como las posibles complicaciones asociadas a la extracción dental en estos pacientes. Objetivo: Describir la evidencia científica disponible sobre complicaciones post-exodoncia asociadas a hiperglicemia en pacientes con diabetes mellitus tipo II. Materiales y Métodos: Se realizó una revisión sistemática exploratoria bajo los protocolos de extensión PRISMA-ScR utilizando las bases de datos, PubMed, EBSCO, Scopus y Cochrane Library con los algoritmos de búsqueda (("Diabetic patient complications" AND "Dental extractions")), (("Diabetes"AND "Tooth extraction")), (("Glycemia" AND "tooth extraction complications")), (("Blood glucose" AND "Tooth extractions")), (("Dental extraction sockets"AND "Diabetics")). Resultado: De un total de 973 artículos se incluyeron 25 artículos para esta revisión. Se consideraron 6 criterios de pertinencia, los cuales mostraron parámetros de seguridad para realizar exodoncias, en pacientes con DM2, con la glucemia capilar no mayor a 200mg/dl en caso de ser electiva y 240 mg/dl en exodoncia de urgencias. Conclusión: Existe poca evidencia que correlacione valores absolutos de hiperglucemia y complicaciones post exodoncia en pacientes con DM2. La mayoría de los autores concuerda en que el problema no es la DM2, sino la hiperglucemia. Existe poca uniformidad en los protocolos de atención recomendados para estos pacientes.

Pharmacotherapeutic potential of Vitis vinifera(grape) in age-related neurological diseases / Potencial farmacoterapéutico de Vitis vinifera(uva) en enfermedades neurológicas asociadas a la edad

Age-related neurological disorders (ANDs), including neurodegenerative diseases, are complex illnesses with an increasing risk with advancing years. The central nervous system's neuropathological conditions, including oxidative stress, neuroinflammation, and protein misfolding, are what define ANDs. Due to the rise in age-dependent prevalence, efforts have been made to combat ANDs. Vitis viniferahas a long history of usageto treat a variety of illness symptoms. Because multiple ligand sites may be targeted, Vitis viniferacomponents can be employed to treat ANDs. This is demonstrated by the link between the structure and action of these compounds. This review demonstrates that Vitis viniferaand its constituents, including flavonoids, phenolic compounds, stilbenoidsandaromatic acids, are effective at reducing the neurological symptoms and pathological conditions of ANDs. This is done by acting as an antioxidant and anti-inflammatory. The active Vitis vinifera ingredients have therapeutic effects on ANDs, as this review explains.

Las enfermedades neurológicas asociadas a la edad (AND, por su sigla en inglés) incluyendo las enfermedades neurodegenerativas, son enfermedades complejas con un riesgo creciente con la edad. Las condiciones neuropatológicas del sistema nervioso central, que incluyen el estrés oxidativo, la neuro inflamación, y el plegado erróneo de proteínas, son lo que define las AND. Debido al aumento en la prevalencia dependiente de la edad, se han hecho esfuerzos para combatir las AND. Vitis vinifera tiene una larga historia de uso para el tratamiento de síntomas. Puesto que puede hacer objetivo a muchos sitios ligando, los componentes de Vitis viniferase pueden utilizar para tratar AND. Esto se demuestra por el vínculo entre la estructura y la acción de estos compuestos. Esta revisión demuestra que la Vitis viniferay sus constituyentes, incluídos los flavonoides, componentes fenólicos, estilbenoides, y ácidos aromáticos, son efectivos para reducir los síntomas neurológicos y las condiciones patológicas de AND. Esto se produce por su acción como antioxidante y antiinflamatorio. Los ingredientes activos de Vitis vinifera tienen efectos terapéuticos en AND, y esta revisión lo explica.

Podocituria y preeclampsia

El podocito es una célula altamente diferenciada localizada en la membrana basal del glomérulo. Entre sus múltiples funciones está garantizar la integridad y funcionalidad de la principal unidad de filtración del riñón, pero carece de la capacidad de dividirse bajo condiciones normales y en situaciones de estrés presenta el riesgo de separarse de la membrana basal, lo que conlleva la posibilidad de desarrollar proteinuria como primer paso de un daño renal que puede llegar a ser permanente. Una de estas situaciones de estrés es el embarazo y, en particular, los trastornos hipertensivos gestacionales, lo que coloca al podocito en la peculiar posición de poderse utilizar como prueba diagnóstica o como marcador de pronóstico renal a largo plazo. En esta revisión veremos el papel del podocito en estos escenarios. (provisto por Infomedic International)

The podocyte is a highly differentiated cell located in the basement membrane of the glomerulus. Among its multiple functions is to guarantee the integrity and functionality of the main filtration unit of the kidney, but it lacks the capacity to divide under normal conditions and in stressful situations it presents the risk of separating from the basement membrane, leading to the possibility of developing proteinuria as the first step of renal damage that may become permanent. One of these stressful situations is pregnancy and, in particular, gestational hypertensive disorders, which places the podocyte in the peculiar position of being able to be used as a diagnostic test or as a marker of long-term renal prognosis. In this review we will look at the role of the podocyte in these scenarios. (provided by Infomedic International)

Nefropatía membranosa: genética, antígenos y anticuerpos

La nefropatía membranosa es un trastorno renal caracterizado por el engrosamiento de la membrana basal glomerular, que causa el síndrome nefrótico. Puede deberse a diversas afecciones subyacentes que provocan daños en las unidades de filtración de los riñones, conocidas como nefronas, produciendo proteinuria masiva, hipoalbuminemia, edema e hiperlipidemia. Entre el 30 y el 40% de los casos de síndrome nefrótico en adultos se deben a una nefropatía membranosa. En las últimas décadas se ha avanzado en el descubrimiento de antígenos, anticuerpos y genes implicados en la fisiopatología de la enfermedad y se ha propuesto un nuevo sistema de clasificación. La presencia de complejos antígeno-anticuerpo junto con factores genéticos puede influir en la susceptibilidad a dicha desregulación inmunológica, y establece nueva información en un lo que se conocía entre las etiologías de causas primarias y secundarias.La comprensión de los antígenos implicados en la nefropatía membranosa es un área de investigación activa, y es posible que se identifiquen antígenos adicionales a medida que nuestro conocimiento de la enfermedad siga evolucionando. Este artículo resume algunos conceptos y hallazgos recientes sobre este tema. (provisto por Infomedic International)

Membranous nephropathy is a kidney disorder characterized by thickening of the glomerular basement membrane, that causes nephrotic syndrome. It can be caused by various underlying conditions that result in damage to the filtering units of the kidneys, known as nephrons, producing massive proteinuria, hypoalbuminemia, edema and hyperlipidemia.  Between 30 to 40% of cases of nephrotic syndrome in adults are due to membranous nephropathy. In recent decades, progress has been made with the discovery of antigens, antibodies and genes involved in the pathophysiology of the disease and a new classification system has been proposed. The presence of antigen-antibody complexes together with genetic factors may influence the susceptibility to such immune dysregulation, and states new information in a what was known between the etiologies of primary and secondary causes. The understanding of the antigens involved in membranous nephropathy is an area of active research, and additional antigens may be identified as our knowledge of the disease continues to evolve. This article summarizes some concepts and recent findings made on this topic. (provided by Infomedic International)

Siendo la depresión una problemática con altas prevalencias y diversas complicaciones, es una tarea ineludible de los clínicos poder entender cómo ocurre el proceso de cambio en pacientes con este diagnóstico. Por ello, este estudio tiene como objetivo realizar una revisión sistemática de la literatura, para explorar y analizar la investigación empírica del proceso de cambio en psicoterapia individual en la adultez en pacientes con depresión, en los últimos diez años. La revisión se realizó en las bases de datos Web of Science, APA PsycNet, PubMed y EBSCO, siguiendo los lineamientos que señala la metodología PRISMA. Luego del proceso de tamizaje y revisión, se seleccionaron y analizaron 39 artículos. Se aprecia una clara tendencia a la utilización de metodologías mixtas de investigación, es decir, cualitativas y cuantitativas, con diseños longitudinales en casi la totalidad de estudios y una amplia gama de instrumentos para la recolección de datos. Los resultados sugieren que el proceso de cambio suele seguir un desarrollo no lineal, originando comúnmente cambios positivos profundos en áreas diversas y con trayectorias que tienden a patrones comunes.

Change process research in psychotherapy is the study of the processes by which change occurs in psychotherapy. Since depression is a problem with high prevalence and various complications, it is an unavoidable task for clinicians to be able to understand how the process of change occurs in patients with this diagnosis. Therefore, this study aims to carry out a systematic review of the literature, to explore and analyze the empirical investigation of the process of change in individual psychotherapy in adulthood in patients with depression, in the last ten years. The review was carried out in the Web of Science, APA PsycNet, PubMed and EBSCO databases, following the guidelines indicated by the PRISMA methodology. After the screening and review process, 39 articles were selected and analyzed. There is a clear tendency to use mixed research methodologies, that is, qualitative and quantitative, with longitudinal designs in almost all the studies and a wide range of instruments for data collection. The results suggest that the change process tends to follow a non-linear development, commonly causing deep positive changes in diverse areas and with trajectories that tend to common patterns.

Recent molecular techniques to strengthen ecological studies in echinoderms / Técnicas moleculares recientes que fortalecen los estudios ecológicos de equinodermos

Abstract Introduction: Echinoderms, an integral component of marine ecosystems worldwide, have captivated scientific interest for centuries. Despite this longstanding attention, comprehending key facets such as trophic relationships, diet composition, and host-microbiota relationships still represents a challenge using traditional techniques. Recent years, however, have witnessed a transformative shift, thanks to the emergence of advanced molecular techniques, offering new approaches to strengthen ecological studies in echinoderms. Objective: Explore how recent advancements in molecular tools have impacted ecological research on echinoderms. Specifically, we aim to investigate the potential of these tools to shed light on trophic interactions, diet composition, and the characterization of gut microbial communities in these organisms. Methods: Available literature was used to clarify how novel molecular techniques can improve ecological studies. The focus is diet, trophic relationships, and gut microbiota. Results: Traditionally, studies of stomach contents using compound microscopy have provided an idea of ingested material; nevertheless, sometimes a simple magnified visualization of dietary content does not allow exhaustive identification of the entire food spectrum, as it is limited due to the rapid digestion and maceration of food items within the echinoderm's digestive tract. The use of DNA-metabarcoding, targeting specific DNA regions, such as the mitochondrial COI gene, has allowed us to enhance the accuracy and precision of diet characterization by enabling the identification of prey items down to the species or even genetic variant level, providing valuable insights into specific dietary preferences. Another approach is the use of stable isotopes, particularly carbon and nitrogen, which provide a powerful tool to trace the origin and flow of nutrients through food webs. By analyzing the isotopic signatures in muscular tissues and food items, we can discern the sources of their primary food items and gain insights into their trophic position within the ecosystem. Lastly, a third new technique used to elucidate the characterization of the prokaryotic community is 16S rRNA sequencing. This method allows us to explore the composition and dynamics of the digestive tract microbial communities. Conclusions: This is a promising era for ecological research on echinoderms, where advances of molecular tools have enabled an unprecedented level of detail, resolving longstanding challenges in comprehending their trophic interactions, diet composition, and host-microbiota relationships, and opening new avenues of investigation in ecological studies.

Resumen Introducción: Los equinodermos, un componente integral de los ecosistemas marinos en todo el mundo, han captado el interés científico durante siglos. A pesar de esta prolongada atención, el comprender facetas clave como las relaciones tróficas, la composición de la dieta y las relaciones huésped-microbiota todavía representa un desafío utilizando técnicas tradicionales. Sin embargo, los últimos años han sido testigos de un cambio transformador, gracias a la aparición de técnicas moleculares avanzadas, que ofrecen nuevos enfoques para fortalecer los estudios ecológicos en equinodermos. Objetivo: Explorar cómo los avances recientes en herramientas moleculares han impactado la investigación ecológica sobre equinodermos. Específicamente, nuestro objetivo es investigar el potencial de estas herramientas para arrojar luz sobre las interacciones tróficas, la composición de la dieta y la caracterización de las comunidades microbianas intestinales en estos organismos. Métodos: Se utilizó la literatura disponible para aclarar cómo las nuevas técnicas moleculares pueden mejorar los estudios ecológicos. La atención se centra en la dieta, las relaciones tróficas y la microbiota intestinal. Resultados: Tradicionalmente, los estudios del contenido estomacal mediante microscopía compuesta han proporcionado una idea del material ingerido; Sin embargo, a veces una simple visualización ampliada del contenido dietético no permite una identificación exhaustiva de todo el espectro alimentario, ya que está limitado debido a la rápida digestión y maceración de los alimentos dentro del tracto digestivo del equinodermo. El uso de metabarcoding de ADN, dirigidos a regiones específicas del ADN, como el gen COI mitocondrial, nos ha permitido mejorar la exactitud y precisión de la caracterización de la dieta al permitir la identificación de presas hasta el nivel de especie o incluso de variante genética, lo que proporciona valiosos resultados sobre preferencias dietéticas específicas. Otro enfoque es el uso de isótopos estables, en particular carbono y nitrógeno, que proporcionan una poderosa herramienta para rastrear el origen y el flujo de nutrientes a través de las redes alimentarias. Al analizar las firmas isotópicas en los tejidos musculares y los alimentos, podemos discernir las fuentes de sus alimentos primarios y obtener información sobre su posición trófica dentro del ecosistema. Por último, una tercera técnica nueva utilizada para dilucidar la caracterización de la comunidad procariótica es la secuenciación del ARNr 16S. Este método nos permite explorar la composición y dinámica de las comunidades microbianas del tracto digestivo. Conclusiones: Esta es una era prometedora para la investigación ecológica sobre equinodermos, donde los avances de las herramientas moleculares han permitido un nivel de detalle sin precedentes, resolviendo desafíos de larga data en la comprensión de sus interacciones tróficas, composición de la dieta y relaciones huésped-microbiota, y abriendo nuevas vías de investigación. en estudios ecológicos.

Application of multiplanar reconstruction and 3D printing in anterior cruciate ligament revision / 中南大学学报(医学版)

Objective:Anterior cruciate ligament injury is the most common type of knee joint ligament injury.Anterior cruciate ligament reconstruction has a high failure rate,with bone tunnel abnormalities as the most significant factor in these failures.Digital orthopedic technology can effectively develop implementation plans for the revision,thus increasing the success rate.This study aims to develop a surgical plan for anterior cruciate ligament revision by employing multiplanar reconstruction(MPR)for measuring bone tunnel position and diameter,and simulating bone tunnel creation via 3D printing preoperatively. Methods:A total of 12 patients who underwent anterior cruciate ligament revision at the Third Xiangya Hospital of Central South University between 2014 and 2021 were retrospectively studied.The data included patient demographics,preoperative formulated knee joint 3D printing models,and preoperative knee CT scans.The study measured the bone tunnel's diameter and position to guide the establishment of revision bone tunnels during surgery,reassessed the postoperative bone tunnels,and evaluated knee joint functional scores[including International Knee Documentation Committee Knee Evaluation Form(IKDC)score,Lysholm score,and Tegner exercise level score]. Results:Preoperative measurements revealed suboptimal femoral tunnels positions in 4 patients and tibial tunnels positions in 2 patients.MPR and 3D printing technology were used to guide the establishment of a new bone canal during surgery,and postoperative measurements were satisfactory for all patients.Preoperative measurements demonstrated the interclass correlation coefficient for femoral tunnels and tibial tunnels diameters were 0.843(P<0.05)and 0.889(P<0.001),respectively.Meanwhile,the intraclass correlation coefficient were 0.811(P<0.05)and 0.784(P<0.05),respectively.The intraoperative diameter of femoral and tibial tunnels showed excellent correlation with postoperative CT measurements,with intraclass correlation coefficient values of 0.995(P<0.001)and 0.987(P<0.001),respectively.All bone tunnel positions were within the normal range.At the final follow-up,knee joint function scores in all 12 patients improved significantly compared to pre-surgery(P<0.001),and the reoperation rate was zero. Conclusion:MPR and 3D printing technology can accurately measure the parameters of reconstructed anterior cruciate ligament bone tunnels.Personalized revision plans for patients with reconstruction failure enhances the success rate of revision surgery and improves patient prognosis.

Application of different grafts in anterior cruciate ligament revision / 中国组织工程研究

BACKGROUND:The type of graft selected during anterior cruciate ligament revision is considered one of the main factors affecting the postoperative outcome,but there are few reports on the comparison between different graft materials. OBJECTIVE:To explore the medium-to-long-term clinical efficacy after anterior cruciate ligament revision with autologous ligament,allogeneic ligament,and LARS artificial ligament. METHODS:A total of 67 patients with the first anterior cruciate ligament revision admitted to the Department of Joint and Sports Medicine,The Second Hospital of Tangshan from May 2011 to May 2020 were selected,including 41 males and 26 females,with a mean age of(45.83±7.39)years.They were divided into three groups according to different grafts used:autologous ligament group(n=24),allogeneic ligament group(n=22),and LARS artificial ligament group(n=21).Follow-up for more than 36 months after revision was performed to evaluate the effect of revision. RESULTS AND CONCLUSION:(1)International Knee Documentation Committee(IKDC)score,Lysholm knee score,and Tegner motor score 1 year after surgery and at the last follow-up in the three groups were higher than those before surgery(P<0.05).There were no significant differences in IKDC score,Lysholm knee score,and Tegner motor score among the three groups 1 year after surgery and the last follow-up(P>0.05).(2)The lateral differences of KT-1000 at 1 year after surgery and the last follow-up among the three groups were lower than those before surgery(P<0.05).The lateral difference of KT-1000 and the positive rate of the axial shift test in the last follow-up of the LARS artificial ligament group were higher than those in the autologous ligament group and allogeneic ligament group(P<0.05).(3)At the last follow-up,X-ray films showed no obvious enlargement of the reconstructed bone tunnel and no obvious failure of the graft fixation device.There was no obvious aggravation of osteoarthritis,but bone density decreased significantly in some elderly patients.(4)These findings suggest that anterior cruciate ligament revision with LARS artificial ligaments can obtain good initial stability,but with the extension of time,the stability of partial cases tends to decrease,even with reconstructed ligament failure.Both allogeneic and autogenous ligaments can obtain good clinical efficacy in anterior cruciate ligament revision.

Mechanical analysis of cortical bone trajectory screw placement in lumbar revision / 中国组织工程研究

BACKGROUND:At present,there are shortcomings and risks in the surgical revision of vertebral bodies that failed to be fixed in clinical practice.To avoid the risks of conventional revision surgery,the cortical bone trajectory technique is used to perform revision surgery on vertebral bodies that failed to be fixed.However,the mechanical properties of cortical bone trajectory technique screws in revision surgery are not clear. OBJECTIVE:The mechanical properties of cortical bone trajectory in lumbar revision surgery were analyzed by the finite element method to provide a theoretical basis for the clinical application of cortical bone trajectory in revision surgery. METHODS:CT scan data of the osteoporotic vertebral body were obtained and the L4 vertebral body model was established.The initial cortical bone trajectory placement and traditional pedicle screw in the L4 vertebral body model were completed,respectively,and their mechanical data were taken as the baseline standard for later evaluation of revision surgical performance.The traditional pedicle screw was removed and the screw path was retained.The cortical bone trajectory screw was used for secondary screw placement on the vertebral body to achieve lumbar refixation.The axial pull-out force,stability,and lumbar motion range of the revised screw were analyzed by the finite element method. RESULTS AND CONCLUSION:(1)The screw axial pull-out force of the cortical bone trajectory revision group was 25.6%higher than that of the traditional pedicle initial group.(2)In the lower,left,and right working conditions,the load-displacement ratio of screws in the cortical bone trajectory revision group increased by 18.5%,41.3%,and 35.0%,respectively,compared with the traditional pedicle initial group.The load-displacement ratio of screws in the cortical bone trajectory revision group was slightly higher than that in the traditional pedicle initial group under the above condition,but there was no statistically significant difference(P>0.05).(3)In anterior and posterior flexion conditions,lumbar motion range in the cortical bone trajectory revision group was increased by 45.5%and 36.1%compared with the traditional pedicle initial group,but there was no statistically significant difference in left bend,right bend,and axial rotation conditions(P>0.05).(4)There were no statistically significant differences in screw axial pull-out force,screw load-displacement ratio,and lumbar motion range between the cortical bone trajectory revision group and cortical bone trajectory initial group(P>0.05).(5)The mechanical data exhibited that although the revised nail track bone was damaged or lost to a certain extent,the mechanical properties of the cortical bone trajectory revision group were still better than those of the traditional pedicle initial group to a certain extent.Moreover,there was no significant difference in the mechanical properties between the cortical bone trajectory revision group and the cortical bone trajectory initial group.It provides a reference for revision surgery of lumbar internal fixation with cortical bone trajectory technique in patients with failed traditional pedicle fixation.

Risk factors and establishment of a nomogram prediction model for hypoproteinemia after hip revision / 中国组织工程研究

BACKGROUND:The high rate of postoperative hypoproteinemia in patients undergoing hip revision is associated with severe trauma,which affects the rapid recovery of patients. OBJECTIVE:To investigate the risk factors of perioperative hypoproteinemia in patients with hip revision,and to provide guidance for early screening of high-risk patients with postoperative hypoproteinemia. METHODS:According to the inclusion and exclusion criteria,161 patients who underwent hip revision were divided into hypoproteinemia group(76 cases)and normal group(85 cases).The rate of hypoproteinemia was 47.2%.Data such as age,gender,body mass index,osteoporosis,operation time,preoperative erythrocytes,preoperative hemoglobin,preoperative leukocytes,preoperative platelets,preoperative fibrinogen,preoperative C-reaction protein,preoperative sedimentation rate,preoperative blood calcium,preoperative albumin,postoperative drainage tube placement,American Society of Anesthesiologists score,and postoperative hypoproteinemia were collected.SPSS software was used to analyze the independent risk factors of hypoproteinemia after hip revision using multivariate binary logistic regression analysis.R software was used to construct the nomogram prediction model.Receiver operating characteristic curve and calibration curve and decision curve were drawn to evaluate the model. RESULTS AND CONCLUSION:(1)Univariate analysis results showed that body mass index,preoperative erythrocytes,preoperative hemoglobin,preoperative platelets,preoperative fibrinogen,preoperative C-reaction protein,and operation time were significantly different between the two groups(P<0.05).(2)Multivariate binary Logistic regression analysis results showed that body mass index(OR=0.859,P=0.021),operation time(OR=1.010,P=0.002),preoperative erythrocytes(OR=0.424,P=0.036),and preoperative C-reaction protein(OR=1.043,P=0.032)levels were independent risk factors for postoperative hypoproteinemia in patients with hip revision.(3)Based on four independent risk factors:body mass index,operation time,preoperative erythrocytes and preoperative C-reaction protein,the nomogram can effectively predict the risk of hypoproteinemia after hip revision.This nomogram prediction model has good differentiation and accuracy,and may lead to better clinical net benefits for patients.
