Published: December 2024

Generalmente, la ley de ablandamiento de un material cuasi-frágil no se considera como un parámetro importante al momento de seleccionar el modelo matemático a emplear para la ejecución de un análisis no-lineal de una estructura y/o elemento estructural elaborado con dicho material. Sin embargo, es de esperarse que el ablandamiento de un material en particular no siempre sea igual, especialmente si consideramos a los materiales compuestos elaborados in-situ y/o que dependen de componentes cuyo origen y, en consecuencia, sus características pueden ser muy diversas, e.g., el concreto y la mampostería. Uno de los modelos matemáticos que ha demostrado ser computacionalmente eficiente en la aproximación del comportamiento no-lineal de estructuras, elaboradas con materiales cuasi-frágiles, consiste en la ejecución de análisis lineales secuenciales. Originalmente, en este modelo se asume una ley de ablandamiento lineal, y ha sido modificado por otros autores que han propuesto otras formas, independientemente de ello, la forma de la ley de ablandamiento que se elija deberá ser la misma en cada aplicación del modelo. Por esta razón, en este trabajo se presenta una modificación al modelo de análisis lineales secuenciales para que la ley de ablandamiento se ajuste mediante aproximación multilineal a cualquier forma, e.g., la obtenida mediante un experimento. Los resultados obtenidos en este trabajo muestran que la aproximación al comportamiento no-lineal experimental de una prueba de tres puntos de flexión mejora considerablemente con el ajuste propuesto.

Los sistemas productivos con ganadería juegan un papel fundamental en la pérdida de bosques nativos, ya que, en el manejo bajo un sistema convencional a cielo abierto, se reemplaza la cobertura arbórea por pastos exóticos, afectando la biodiversidad y los nutrientes del suelo.
Por otro lado, otro sistema de producción es el denominado silvopastoril donde se incluyen árboles nativos o exóticos, reduciendo algunos de esos efectos adversos del manejo convencional. En ambos casos, los escarabajos estercoleros son esenciales ya que se alimentan del estiércol vacuno manipulándolo y enterrándolo, promoviendo diferentes funciones ecológicas que incrementan la calidad del suelo. El objetivo de este trabajo fue determinar la influencia de dos sistemas de producción con ganadería (a cielo abierto: CA y silvopastoril: SSP) y la actividad de los escarabajos estercoleros sobre la biomasa seca de pasturas y sobre el ciclaje de los nutrientes del suelo en el norte de Misiones. Se realizó un experimento en diversos campos, comparando dos tratamientos: con y sin escarabajos estercoleros. Se cuantificó la biomasa seca de pasturas de la especie Brachiaria bizantha y se analizó la dotación de nutrientes del suelo. La biomasa seca de pasturas y el contenido de fósforo fue mayor en los sistemas productivos ganaderos con un manejo a cielo abierto, en comparación con silvopastoriles, respectivamente. La presencia de árboles afectó negativamente la producción de pasturas y el contenido de nutrientes en el suelo, probablemente por un exceso de sombreado.
Por otro lado, no se observó ningún efecto asociado con la actividad de los escarabajos estercoleros.

Authors:   Korean Society for Leisure Scie, Zhang Zikang , Lim Jinsun , Park Jiwon
Published: December 2024

This study sought to determine the relationship between acculturation stress and life satisfaction of international students based on their ability to cope with stress related to leisure activities in Korea. In order to examine this issue, data were collected through purposive sampling of 264 international students by setting the residence period to 3 years or less during the month of March 2023, and the results of the analysis showed the following two results. First, when their ability to cope with leisure stress was high, it was confirmed that their acculturation stress had a positive effect on life satisfaction. I believe this proves that they are having a positive impact on their adaptation to Korean society. Second, when their ability to cope with leisure stress was low, their acculturation stress did not appear to affect their life satisfaction. This showed that acculturation stress in their lives was of no significance to life satisfaction. Although acculturation stress may be an issue that may have a low impact on international students due to the Korean Wave, we must recognize the importance of providing programs that allow them to have appropriate leisure experiences.

Laparoscopic liver resection utilizing the ventral avascular area of the inferior vena cava: A retrospective cohort study
Authors: Huang Kun , Chen Zhu , Xiao Heng , Hu Hai-Yang , Chen Xing-Yu , Du Cheng-You , Lan Xiang
Published: December 2024

BACKGROUND

Laparoscopic liver resection (LLR) can be challenging due to the difficulty of establishing a retrohepatic tunnel under laparoscopy. Dissecting the third hepatic hilum before parenchymal transection often leads to significant liver mobilization, tumor compression, and bleeding from the short hepatic veins (SHVs). This study introduces a novel technique utilizing the ventral avascular area of the inferior vena cava (IVC), allowing SHVs to be addressed after parenchymal transection, thereby reducing surgical complexity and improving outcomes in in situ LLR.

AIM

To introduce and evaluate a novel LLR technique using the ventral avascular area of the IVC and compare its short-term outcomes with conventional methods.

METHODS

The clinical cohort data of patients with pathologically confirmed hepatocellular carcinoma or intrahepatic cholangiocarcinoma who underwent conventional LLR and novel LLR between July 2021 and July 2023 at the First Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. In novel LLR, we initially separated the caudate lobe from the IVC using dissecting forceps along the ventral avascular area of the IVC. Then, we transected the parenchyma of the left and right caudate lobes from the caudal side to the cephalic side using the avascular area as a marker. Subsequently, we addressed the SHVs and finally dissected the root of the right hepatic vein or left hepatic vein. The short-term postoperative outcomes and oncological results of the two approaches were evaluated and compared.

RESULTS

A total of 256 patients were included, with 150 (58.59%) undergoing conventional LLR and 106 (41.41%) undergoing novel LLR. The novel technique resulted in significantly larger tumor resections (6.47 ± 2.96 cm vs 4.01 ± 2.33 cm, P < 0.001), shorter operative times (199.57 ± 60.37 minutes vs 262.33 ± 83.90 minutes, P < 0.001), less intraoperative blood loss (206.92 ± 37.09 mL vs 363.34 ± 131.27 mL, P < 0.001), and greater resection volume (345.11 ± 31.40 mL vs 264.38 ± 31.98 mL, P < 0.001) compared to conventional LLR.

CONCLUSION

This novel technique enhances liver resection outcomes by reducing intraoperative complications such as bleeding and tumor compression. It facilitates a safer, in situ removal of complex liver tumors, even in challenging anatomical locations. Compared to conventional methods, this technique offers significant advantages, including reduced operative time, blood loss, and improved overall surgical efficiency.

Pancreatic cysts are mostly incidental findings on computed tomography or magnetic resonance imaging scans, with few patients presenting with abdominal pain or other symptoms. The accurate diagnosis of cysts is important as management depends on the type (neoplastic or non-neoplastic). Cross-sectional imaging is fast being replaced with endoscopic ultrasound (EUS) and various techniques based on that such as EUS-guided fine needle aspiration, EUS-guided needle confocal laser endomicroscopy, EUS-through-the-needle biopsy, and contrast-enhanced EUS. Clinical studies have reported varying diagnostic and adverse event rates with these modalities. In addition, American, European, and Kyoto guidelines for the diagnosis and management of pancreatic cysts have provided different recommendations. In this editorial, we elaborate on the clinical guidelines, recent studies, and comparison of different endoscopic methods for the diagnosis of pancreatic cysts.

Published: December 2024

BACKGROUND

A dual therapy regimen containing amoxicillin is a common treatment option for the eradication of Helicobacter pylori (H. pylori ). While substantial research supports the efficacy and safety of vonoprazan and amoxicillin (VA) dual therapy in the general population, there is still a lack of studies specifically focusing on its safety in elderly patients.

AIM

To evaluate efficacy and safety of VA dual therapy as first-line or rescue treatment for H. pylori in elderly patients.

METHODS

As a real-world retrospective study, data were collected from elderly patients aged 60 years and above who accepted VA dual therapy (vonoprazan 20 mg twice daily + amoxicillin 1000 mg thrice daily for 14 days) for H. pylori eradication in the Department of Gastroenterology at Peking University First Hospital between June 2020 and January 2024. H. pylori status was evaluated by 13C-urease breath test 6 weeks after treatment. All adverse events (AEs) during treatment were recorded.

RESULTS

In total, 401 cases were screened. Twenty-one cases were excluded due to loss to follow-up, lack of re-examination, or unwillingness to take medication. The total of 380 included cases comprised 250 who received VA dual therapy as first-line treatment and 130 who received VA dual therapy as rescue treatment. H. pylori was successfully eradicated in 239 cases (95.6%) in the first-line treatment group and 116 cases (89.2%) in the rescue treatment group. The overall incidence of AEs was 9.5% for both groups. Specifically, 9.2% of patients experienced an AE in the first-line treatment group and 10.0% in the rescue treatment group. Five patients discontinued treatment due to AE, with a discontinuation rate of 1.3%. No serious AE occurred.

CONCLUSION

The VA dual therapy regimen as a first-line treatment and a rescue therapy was effective and safe for elderly patients aged 60 and older.
Creeping fat and gut microbiota in Crohn’s disease
Authors: Quaglio Ana EV , Magro Daniéla O , Imbrizi Marcello , De Oliveira Ellen CS , Di Stasi Luiz C , Sassaki Ligia Y
Published: December 2024

In this article, we explored the role of adipose tissue, especially mesenteric adipose tissue and creeping fat, and its association with the gut microbiota in the pathophysiology and progression of Crohn’s disease (CD). CD is a form of inflammatory bowel disease characterized by chronic inflammation of the gastrointestinal tract, influenced by genetic predisposition, gut microbiota dysbiosis, and environmental factors. Gut microbiota plays a crucial role in modulating immune response and intestinal inflammation and is associated with the onset and progression of CD. Further, visceral adipose tissue, particularly creeping fat, a mesenteric adipose tissue characterized by hypertrophy and fibrosis, has been implicated in CD pathogenesis, inflammation, and fibrosis. The bacteria from the gut microbiota may translocate into mesenteric adipose tissue, contributing to the formation of creeping fat and influencing CD progression. Although creeping fat may be a protective barrier against bacterial invasion, its expansion can damage adjacent tissues, leading to complications. Modulating gut microbiota through interventions such as fecal microbiota transplantation, probiotics, and prebiotics has shown potential in managing CD. However, more research is needed to clarify the mechanisms linking gut dysbiosis, creeping fat, and CD progression and develop targeted therapies for microbiota modulation and fat-related complications in patients with CD.
