Epub 2022 Jan 7. ABSTRACT The overall outcomes for patients with advanced liver cancer are far from satisfactory, and the development of more effective therapeutic strategies for liver cancer is required. Sulforhodamine blue and colony formation assays were performed to detect the proliferation of liver certain cancer cells, including HepG2 and Hep3B. Western blotting was also preformed to detect the expression of indicated proteins, including cleaved-caspase-3, cleaved-poly (ADP-ribose) polymerase, dual-specificity tyrosine phosphorylation kinase 1A (DYRK1A), PARP-1/2, GAPDH, myeloid cell leukemia-1, phosphorylated-AKT (Ser473), caspase-3, α-tubulin and AKT. PI staining was used to detect cell death. In the present study, DYRK1A knockdown significantly enhanced the anti-liver cancer effect of regorafenib in vitro. Furthermore, DYRK1A inhibitor harmine together with regorafenib provided synergistic anti-liver cancer activity by suppressing cell proliferation. In addition, harmine significantly enhanced regorafenib-induced cell death in liver cancer cells. It has been reported that AKT signaling is activated in regorafenib-resistant cancer cells and plays a crucial role in the regulation of cellular sensitivity to regorafenib. In the present study, AKT was activated in regorafenib-treated cells, and harmine could suppress the activation of AKT and reinforce the anti-cancer effects of regorafenib via regulating AKT in liver cancer cells. These data indicated that harmine enhanced the anti-cancer effects of regorafenib on suppressing cell proliferation and inducing apoptosis in liver cancer cells via regulating the activation of AKT, and harmine plus regorafenib may be a potential therapeutic regimen for treating patients with liver cancer.

Minimally invasive treatment and internal fixation vs. extended lateral approach in calcaneus fractures of thalamic interest

xlomafota13 shared this article with you from Inoreader Minimally invasive treatment and internal fixation vs. extended lateral approach in calcaneus fractures of thalamic interest Via Experimental and therapeutic medicine Exp Ther Med. 2022 Mar;23(3):196. doi: 10.3892/etm.2022.11119. Epub 2022 Jan 5. ABSTRACT The extended lateral side approach is a common technique in the surgical treatment of calcaneal fractures, with thalamic collapse offering a good exposure of the fractured site; however, it can be burdened with complications due to soft tissue trauma. The present study aimed to compare patients treated with minimally invasive osteosynthesis through a minimum lateral approach and internal fixation with patients that were treated using internal fixation with an extended lateral side approach in cases of intra-articular calcaneal fractures with thalamic fracture. Patients were evaluated preoperatively and postoperatively by performing clinical and imagistic examinations, with radiography scans of the anterior-posterior calcaneal profile and computer tomography. Furthermore, preoperative and postoperative analyses of the Böhler angle on the radiologic al profile, complications and duration of the hospital admission for both groups were performed. There were 36 patients (39 calcaneal fractures) in group 1 and 24 patients (29 calcaneal fractures) in group 2. The results demonstrated no statistically significant differences in the preoperative (P=0.72) and postoperative (P=0.20) Böhler angle values. The postoperative Böhler angle average values were 26.9 in group 1 and 29.3 in group 2. A total of 11 patients were treated with Kirschner wires inserted in the calcaneus, and in 2/ll cases, one of the brooches registered a migration movement. There were no cases of material migration in the fractures that were stabilized by inserting Kirschner brooches up to the astragalus and cuboid bones. Taken together, the results of the present study demonstrated no significant differences in the Böhler angle values between the minimally invasive and open reduction techniques. However, the antibiotic therapy period, as well as the infection rate were lower in patients that were treated using the minimally invasive technique, suggesting that this technique was superior with respect to lower complication rates and improved functional results.

An original method of simulating the articular cartilage in the context of in vitro biomechanical studies investigating the proximal femur

xlomafota13 shared this article with you from Inoreader An original method of simulating the articular cartilage in the context of <em>in vitro</em> biomechanical studies investigating the proximal femur Via Experimental and therapeutic medicine Exp Ther Med. 2022 Mar;23(3):202. doi: 10.3892/etm.2022.11125. Epub 2022 Jan 5. ABSTRACT Biomechanical testing is a necessity given the development of novel implants used in the osteosynthesis of hip fractures. The purpose of biomechanical testing is to recreate realistic conditions similar to the in vivo conditions. Although biomechanical testing of hip arthroplasty has been standardized since the 1970s, there is no consensus at present on testing methodology for osteosynthesis of hip fractures. Most biomechanical studies examining the fractures of the proximal femur in order to optimize implants opt for loading the bone-implant ensemble directly on the femoral head or using a metallic loading part. This loading technique fails to perform a mechanical stress distribution similar to in vivo conditions, which could alter the outcome. The present study aimed to design loading/unloading cups with mechanical properties that r esemble those of the cartilage at the hip level. Through the impression and scanning of the cast models obtained, a digital 3D model was created in STL format and this was processed in order to obtain the computer numerical control (CNC) trajectories of the printing head. For prototyping using additive manufacturing technology, a thermoplastic polymer with biochemical properties, such as tensile strength, that resemble those of the adult hip and a Stratasys FORTUS 250 mc CNC machine were used. Loading/unloading cups with similar anatomy and biomechanical forces compared with those of the adult hip were created, which allowed the experimental simulation of the conditions during walking.

Delineating the risk factors of venous congestion: An analysis of 455 deep inferior epigastric perforator flaps with radiographic correlation

xlomafota13 shared this article with you from Inoreader Delineating the risk factors of venous congestion: An analysis of 455 deep inferior epigastric perforator flaps with radiographic correlation Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2022 Jan 16:S1748-6815(22)00017-1. doi: 10.1016/j.bjps.2022.01.003. Online ahead of print. ABSTRACT BACKGROUND: Venous congestion occurs in 2-15% of DIEP flaps for breast reconstruction. We previously showed that thicker suprascarpal fat pads are associated with increased SIEV caliber and may, by extension, indicate a dominant superficial venous system. In this study, we aim to provide clinical correlation and to determine the risk factors of venous congestion in order to identify high-risk patients who may benefit from prophylactic SIEV dissection. METHODS: An IRB-approved retrospective study was performed in patients who underwent DIEP flap reconstruction from August 2011 to August 2020. Radiographic measurements of suprascarpal fat pad thickness and SIEV diameter were collected per hemi-abdomen from preoperative imaging. The statistical analysis explored whether certain variables were associated with venous congestion. RESULTS: A total of 258 patients underwent 455 DIEP flaps. Suprascarpal fat pad thickness was positively correlated with SIEV diameter (r = 0.51, p<0.001), each with a mean caliber of 19.8 mm and 2.5 mm, respectively. Seven flaps (1.5%) developed venous congestion, with five requiring SIEV salvage and secondary venous anastomosis. Congested flaps had significantly thinner suprascarpal fat pads (12.3 vs. 20.0 mm, p = 0.043). All six congested flaps with imaging had suprascarpal thickness less than 18 mm, compared to 182 out of 335 non-congested flaps with imaging (p = 0.035). CONCLUSIONS: The risk of venous congestion following DIEP flap reconstruction is significantly increased with thinner suprascarpal fat pads, suggesting that the mechanism of venous congestion may not be limited to superficial venous dominance. We recommend prophylactic SIEV dissection in all patients with suprascarpal fat pad thickness less than 18 mm. PMID:35125307 | DOI:10.1016/j.bjps.2022.01.003 View on the web Inoreader.

Eye manifestations in the NSUN2 intellectual disability syndrome

xlomafota13 shared this article with you from Inoreader Eye manifestations in the <em>NSUN2</em> intellectual disability syndrome Via International Journal of Molecular Epidemiology and Genetics Int J Mol Epidemiol Genet. 2021 Dec 15;12(6):129-134. eCollection 2021. ABSTRACT The NSUN2-intellectual disability syndrome is a rare disorder of the cellular transcriptome that prevents proper t-RNA splicing. This disorder interrupts cellular function and leads to an accumulation of RNA fragments, producing a constellation of symptoms including dysmorphic facies, hypotonia, microcephaly, and short stature. Eye manifestations have been reported but not well characterized. Our study presents a new case involving a 4-year-old boy with novel NSUN2 variants and clinical features consistent with the syndrome. In addition, through a systemic review, we discuss the 24 previously reported cases of the syndrome with an emphasis on the eye and ocular adnexa clinical features.

Indicadores de calidad en la atención de salud en cirugía oncológica de cabeza y cuello

xlomafota13 shared this article with you from Inoreader Indicadores de calidad en la atención de salud en cirugía oncológica de cabeza y cuello Via Otorrinolaringología y cirugía de cabeza y cuello Resumen La mayoría de los servicios de salud han experimentado un aumento de los costos asociados a la atención de salud lo que ha llevado a adoptar medidas para optimizar la costo-efectividad de los servicios otorgados. Desde esa perspectiva surge la atención de salud basada en el valor. El concepto de "calidad en la atención de salud" se ha definido como el grado en el cual los servicios de salud aumentan la posibilidad de generar ciertos desenlaces en salud a los que se aspira. Los indicadores de calidad de clasifican en indicadores de estructura, de proceso, y de desenlace. Los indicadores de estructura se refieren a las características del sistema de salud o de la institución hospitalaria. Los indicadores de proceso se refieren a los que el proveedor de servicios de salud realiza para el proceso de atención en salud, mientras que los indicadores de desenlace se refieren a los resultados del proceso en el paciente. El objetivo de la presente revisión es proveer un marco conceptual para dar un contexto al concepto de indicadores de calidad en salud y el rol que estos juegan en cirugía oncológica de cabeza y cuello. Se debe aspirar a lograr un mayor cumplimiento de los indicadores de calidad en cirugía oncológica de cabeza y cuello, especialmente en instituciones terciarias de referencia. Aplicar indicadores de calidad en el manejo oncológico en cabeza y cuello permitiría mejorar tanto la percepción y satisfacción del usuario, como también mejorar resultados oncológicos en estos pacientes. Abstract Most health services have experienced an increase in the costs associated with health care, which has led to the adoption of measures to optimize the cost-effectiveness of the services provided. From this perspective, the concept of value-based health care emerged. The concept of "quality in health care" has been defined as the degree to which health services increase the possibility of generating certain desired health outcomes. Quality indicators are classified into structure, process, and outcome indicators. The structure indicators refer to the characteristics of the health system or the hospital institution. Process indicators refer to those that the health service provider performs for the health care process, while outcome indicators refer to the results of the process in the patient. The objective of this review is to provide a conceptual framework to give a context to the concept of health quality indicators and the role they play in head and neck surgical oncology. The system should aspire to achieve greater compliance with quality indicators in head and neck cancer surgery, especially in referral tertiary institutions. Applying quality indicators in head and neck cancer management would improve both user perception and satisfaction, as well as improve oncological results in these patients.

Revisión narrativa de instrumentos de autoevaluación vocal en Chile

xlomafota13 shared this article with you from Inoreader Revisión narrativa de instrumentos de autoevaluación vocal en Chile Via Otorrinolaringología y cirugía de cabeza y cuello Resumen Los sujetos disfónicos no siempre presentan una adecuada percepción de su voz o de cómo las alteraciones vocales afectan a su entorno, modificando su calidad de vida. Los protocolos de auto evaluación vocal ayudan al clínico a percibir si el paciente disfónico se siente afectado por sus problemas vocales o no. Existen numerosos protocolos de auto evaluación vocal, sin embargo, pocos de estos están actualmente validados en Chile. Este trabajo corresponde a una revisión narrativa respecto de la validación de instrumentos de autoevaluación vocal en Chile. Se llevó a cabo una búsqueda bibliográfica en: Pubmed, Scielo y Bireme. Fueron empleados los siguientes descriptores: Chile, voz, autoevaluación, calidad de vida, estudios de validación, comparación transcultural y sus respectivos términos en inglés: Chile, voice, validation study, self-assessment, quality of life, crosscultural comparision. Dos restricciones fueron empleadas: las investigaciones debía n estar publicadas en inglés y/o español, con fecha de publicación entre 2008 y 2020. Se encontraron 41 artículos, eliminándose 24 duplicados y 13 de contenidos no relacionados, resultando en 4 artículos analizados correspondientes a 3 instrumentos traducidos al español. El uso de protocolos de autoevaluación vocal complementa la evaluación clínica y objetiva de la voz, contribuyendo con la percepción del paciente, relevante para el tratamiento fonoaudiológico, sin embargo, la cantidad de protocolos de autoevaluación vocal en Chile con traducción, adaptación cultural y validación estandarizada continúa siendo escasa. Abstract Dysphonic subjects do not always present an adequate perception of their voice, or of how vocal alterations affect their environment, modifying their quality of life. Vocal self-as-sessment protocols help the clinician to perceive whether the dysphonic patient feels affected by his vocal problems or not. There are numerous protocols for voca l self-assessment, however, few of these are currently validated in Chile. This work corresponds to a narrative review regarding the validation of vocal self-assessment instruments in Chile. The bibliographic search was conducted in the search sites: Pubmed, Scielo and Bireme. The following descriptors were used: Chile, voice, validation studies, cross-cultural comparison. Two restrictions were used: the research had to be published in English and/or Spanish, with a publication date between 2008 and 2020. A total of 41 articles were found, eliminating 24 duplicates and 13 of unrelated content, resulting in 4 articles analyzed corresponding to 3 instruments translated into Spanish. The use of vocal self-assessment protocols complements the clinical and objective assessment of the voice, contributing to the perception of the patient, relevant for speech therapy, however, the number of vocal self-assessment protocols in Chile with translation, cultural adaptation and standardized valid ation remains sparse.

Adenitis cervical con anaerobios sin causa aparente en lactante

xlomafota13 shared this article with you from Inoreader Adenitis cervical con anaerobios sin causa aparente en lactante Via Otorrinolaringología y cirugía de cabeza y cuello Resumen Las adenopatías cervicales benignas en lactantes son relativamente frecuentes, se definen como el aumento de volumen ganglionar de más de 1 cm, sin síntomas sistémicos y cuando están presentes, el término correcto es adenitis. Para su estudio, las adenitis se dividen en: locales, sistémicas, unilaterales, bilaterales, agudas, crónicas, y por edad, con diferentes etiologías. Se presenta el caso clínico de un lactante de 11 meses de edad con diagnóstico de adenitis cervical abscedada unilateral aguda, con cuadro de 72 h de evolución, con crecimiento constante a nivel cervical derecho, compromiso del estado general, fiebre y anorexia, por lo que se inician antibióticos de primera línea para los agentes bacterianos más frecuentes (Staphylococcus aureus y Streptococcus pyogenes), con evolución tórpida a las 48 h, por lo que se solicita ultrasonido cervical, ya que la familia no contaba con recursos para solicitar cultivo o tomografía, reportando el ultrason ido ganglio cervical de 3,5 cm de diámetro abscedado, por lo que se agrega cobertura para anaerobios, con respuesta muy favorable a las 24 h. Queda la duda del origen de los anaerobios en la paciente, sin antecedentes de importancia y en grupo etario diferente al afectado por esos gérmenes. Consideramos este caso interesante por su comportamiento atípico, para el enriquecimiento del ejercicio de la otorrinolaringología, recalcando el invaluable apoyo de la clínica y solo con un ultrasonido, ya que no siempre se tendrán todos los recursos disponibles, pero siguiendo las pautas de lo reportado en la literatura, se tuvo una resolución exitosa. Abstract Benign cervical lymphadenopathies in infants are relatively frequent, they are defined as an increase in lymph node volume of more than 1 cm, without systemic symptoms, and when they are present, the correct term is adenitis. For its study, adenitis is divided into: local, systemic, unilateral, bilateral, acute, chronic, and by age, with different etiologies. An 11-month-old infant with a diagnosis of acute unilateral abscessed cervical adenitis, with a 72 h evolution, with constant growth at the right cervical level, fever and anorexia, for which first-line antibiotics were started to the most frequent bacterial agents (Staphylococcus aureus and Streptococcus pyogenes), with torpid evolution at 48 h, for which only cervical ultrasound is requested, since the family did not have the resources to request culture or tomography, reporting the cervical ganglion ultrasound of 3.5 cm of abscessed diameter, so coverage for anaerobes is added, with a very favorable response at 24 hrs. There remains the doubt of the origin of the anaerobes in the patient, without important antecedents and in an age group different from that affected by these germs. We consider this case interesting due to its atypical behavior, for the enrichment of the otolaryngology exercise, emphasizing the invaluable support of the clinic, and only with an ultrasound, since other clinical tools were not available, but following the guidelines of what is reported in literature, there was a successful resolution.

Osteotomía Le Fort III modificada en un paciente no sindrómico

xlomafota13 shared this article with you from Inoreader Osteotomía Le Fort III modificada en un paciente no sindrómico Via Otorrinolaringología y cirugía de cabeza y cuello Resumen Las discrepancias dento-esqueletales severas presentan un reto para el cirujano maxilofacial, existe una versatilidad de osteotomías para las diferentes anomalías del crecimiento y desarrollo, sin embargo, son pocas las que permiten mejorar la proyección malar. La osteotomía Le Fort III modificada fue utilizada en un principio en pacientes con algún síndrome craneofacial, pero actualmente es una alternativa útil para discrepancias severas en pacientes no sindrómicos, ya que permite un avance cigomático-maxilar, favorece la proyección malar y disminuye la exposición escleral con un número limitado de complicaciones. Se presenta el caso de un paciente masculino de 33 años con antecedente de fractura orbitocigomática y piso orbitario izquierda con una discrepancia dento-esqueletal severa, la que fue tratada mediante osteotomía Le Fort III modificada, osteotomías sagitales mandibulares para un avance máxilo-malar y retroceso mandibular respectivamente y una genioplastia de avance; logrando un resultado funcional y estético adecuado. Abstract The dento-skeletal severe discrepancies present a challenge for the maxillofacial surgeon, there is a versatility of osteotomies for the different growth and development anomalies, however, a few of them make possible to improve malar projection. The modified Le Fort III osteotomy was originally used in patients with some craniofacial syndrome, but now it is a useful alternative for severe discrepancies in non-syndromic patients, since it allows a zygomatic-maxillary advance, favors malar projection and reduces scleral exposure with a limited number of complications. The case of a 33-year-old male patient with a history of orbitozygomatic fracture and left orbital floor with a severe dento-skeletal discrepancy is presented, who was treated by modified Le Fort III osteotomy, mandibular sagittal osteotomies for maxillo-malar advancement and retrogression mandibular respectively and geniplasty fo r advance; achieving a suitable functional and aesthetic result.
