Deferoxamine preconditioning of canine stem cell derived extracellular vesicles alleviates inflammation in an EAE mouse model through STAT3 regulation.

Extracellular vesicles (EVs) from mesenchymal stem cells (MSCs), specifically those preconditioned with deferoxamine (DFO) in canine adipose tissue-derived MSCs (cAT-MSCs), were explored for treating autoimmune diseases. This study assessed the effects of DFO-preconditioned EVs (EV) in an experimental autoimmune encephalomyelitis (EAE) mouse model. cAT-MSCs were treated with DFO for 48 h, after which EVs were isolated.

A Comparative Study of Postoperative Complications Associated with Distal Gastrectomy and Pylorus-Preserving Gastrectomy among Gastric Cancer Patients Based on Nationwide Survey Data and Propensity Score Weighting.

Background/objective: This study aimed to compare complication rates between pylorus-preserving gastrectomy (PPG) and distal gastrectomy (DG) using Korean nationwide survey data and propensity score weighting (PSW). PPG preserves gastric function but may lead to more postoperative complications than DG.

Methods And Results: We analyzed 9424 gastric cancer patients who underwent either DG ( = 9183) or PPG ( = 241).

Neuroprotective and immunomodulatory effects of superoxide dismutase on SH-SY5Y neuroblastoma cells and RAW264.7 macrophages.

Superoxide dismutase (SOD) is an antioxidant enzyme that protects the body from free radicals. It has both antioxidant and immunomodulatory properties, inducing macrophage polarization from M1 to M2. Macrophages, key mediators of the innate immune response, are divided into the M1 (pro-inflammatory) and M2 (anti-inflammatory) subtypes.

Comparison of Eastern and Western patients undergoing bariatric surgery at two US and Korean institutions: a retrospective analysis of differing bariatric patient populations.

Background: Currently, there are differences in both demographics and indications for bariatric surgery between Eastern and Western countries. We compared postoperative outcomes between Korean and American bariatric programs in order to assess how bariatric surgery differently affects these populations.

Methods: We enrolled 540 patients who underwent bariatric surgery at University of California, Los Angeles (UCLA) and 85 patients who underwent surgery at Kosin University Gospel Hospital (KUGH) between January 2019 and December 2020.

Percutaneous radiologic gastrostomy with single gastropexy using balloon-assisted tract dilatation: comparison with peel-away sheath.

Methods: This retrospective study was approved by the institutional review board. From August 2018 to October 2022, 61 patients (53 male and 8 female, mean age 67 years, age range 27-90 years) underwent PRG with balloon-retained tubes for enteral nutrition.

Complication After Gastrectomy for Gastric Cancer According to Hospital Volume: Based on Korean Gastric Cancer Association-Led Nationwide Survey Data.

Purpose: This study aimed to analyze the incidence and risk factors of complications following gastric cancer surgery in Korea and to compare the correlation between hospital complications based on the annual number of gastrectomies performed.

Materials And Methods: A retrospective analysis was conducted using data from 12,244 patients from 64 Korean institutions. Complications were classified using the Clavien-Dindo classification (CDC).

Amelioration of DSS-induced colitis in mice by TNF-α-stimulated mesenchymal stem cells derived from feline adipose tissue via COX-2/PGE activation.

Background: Mesenchymal stem cells (MSCs) have been investigated as therapeutic agents for inflammatory bowel disease (IBD). Stimulation of MSCs with pro-inflammatory cytokines is an approach to enhance their immunomodulatory effects. However, further investigation is required to support their application in immune-mediated disorders and companion animals.

Treatment and Prevention of Postoperative Leakage after Gastrectomy for Gastric Cancer.

Anastomotic leakage is one of the common causes of serious morbidity and death after gastrectomy. The use of surgical treatment for leakage decreased due to the development of nonsurgical management. However, if nonsurgical management fails to control the spread of intra-abdominal infection, emergency surgical treatment is required.

Prevalence of Non-Alcoholic Fatty Liver Disease (NAFLD) in Korean Patients Undergoing Bariatric Surgery.

Purpose: The number of Korean patients undergoing metabolic surgery for obesity is on the increase. Patients undergoing obesity and metabolic surgery have a body mass index (BMI) ≥30 kg/m. In this study, we investigated the prevalence of nonalcoholic fatty liver disease in Korean patients who had undergone bariatric surgery.

Changes of Guidelines in the Management of Obese Patients With Diabetes in the Metabolic Surgery Perspective.

Recently, metabolic surgery was recommended for patients with a BMI of 30 or higher and 27.5 or higher for Asians, as evidence level A. Until 2008, bariatric surgery was not introduced for the treatment of diabetes.

Efficacy of S-1 or Capecitabine Plus Oxaliplatin Adjuvant Chemotherapy for Stage II or III Gastric Cancer after Curative Gastrectomy: A Systematic Review and Meta-Analysis.

Adjuvant chemotherapy (AC) regimens tegafur/gimeracil/oteracil (S-1) and capecitabine plus oxaliplatin (CAPOX) have predominated, however, there has been a lack of studies on their differences in efficacy. We conducted pairwise meta-analyses comparing the efficacy of S-1 and CAPOX regimens for overall survival (OS) and disease-free survival (DFS) in stage II or III GC patients. Three studies were enrolled and analyzed using a forest plot for meta-analysis.

Short-term outcome of bariatric surgery on nonalcoholic fatty liver disease: a Korean perspective.

Purpose: Obesity is associated with nonalcoholic fatty liver disease, one of the most common causes of chronic liver disease. We aimed to demonstrate the effectiveness of bariatric surgery for hepatic steatosis and fibrosis in Korean patients.

Methods: A total of 32 consecutive patients were enrolled in this study.

Association between the Blautia/Bacteroides Ratio and Altered Body Mass Index after Bariatric Surgery.

Backgruound: Current evidence support that the gut microbiota plays a potential role in obesity. Bariatric surgery can reduce excess weight and decrease the risk of life-threatening weight-related health problems and may also influence gut microbiota. In this study, we aimed to investigate the changes in gut microbiota before and after bariatric surgery and evaluate the association of the gut microbial shift and altered body mass index (BMI) after bariatric surgery.

Risk factors of incisional hernia after laparoscopic colorectal surgery with periumbilical minilaparotomy incision: a propensity score matching analysis.

Purpose: Incisional hernia is one of the most common complications after abdominal surgery conducted through a midline incision. Considerable debate remains regarding the design, comorbidity, suture material, and method. We investigated the risk factors for incisional hernia after laparoscopic colorectal surgery in the presence of limited surgery-related factors.

Comparison of the Clinical Outcomes of Reconstruction Methods After Distal Gastrectomy: A Systematic Review and Meta-Analysis Based on Randomized Controlled Trials.

Background: To analyze the short- and long-term clinical outcomes of 2 reconstruction methods after distal gastrectomy for gastric cancer.

Methods: Three keywords, "gastric neoplasm," "distal gastrectomy," and "reconstruction," were used to search PubMed. We selected only randomized controlled trial that compared the anastomosis methods.

Long-Term Survival Outcomes of Elderly Patients Treated With S-1 or Capecitabine Plus Oxaliplatin for Stage II or III Gastric Cancer: A Multicenter Cohort Study.

Purpose: Tegafur/gimeracil/oteracil (S-1) and capecitabine plus oxaliplatin (CAPOX) are standard adjuvant chemotherapies (ACs) administered after gastrectomy to patients with stage II or III gastric cancer. However, the efficacy of AC in elderly patients remains unclear. The objective of this retrospective multicenter cohort study was to compare the efficacies of S-1 and CAPOX AC in patients aged ≥70 years.

Prospective multicentre randomised clinical trial comparing survival rates, quality of life and nutritional status between advanced gastric cancer patients with different follow-up intensities: study protocol for the STOFOLUP trial.

Introduction: Patients who underwent curative gastrectomy for gastric cancer are regularly followed-up for the early detection of recurrence and postoperative symptom management. However, there is a lack of evidence with regard to proper surveillance intervals and diagnostic tools. This study aims to evaluate whether frequent surveillance tests have a survival benefit or improve the quality of life in patients who underwent curative resection for advanced gastric cancer.

Choice of LECS Procedure for Benign and Malignant Gastric Tumors.

Laparoscopic endoscopic cooperative surgery (LECS) refers to the endoscopic dissection of the mucosal or submucosal layers with laparoscopic seromuscular resection. We recommend a treatment algorithm for the LECS procedure for gastric benign tumors according to the protruding type. In the exophytic type, endoscopic-assisted wedge resection can be performed.

Endoscopic Septotomy as a Treatment for Chronic Leak after Laparoscopic Sleeve Gastrectomy.

Acute leakage after sleeve gastrectomy progresses into chronic leakage by 10-28.1%, which causes the surgeon to be disturbed. The main treatment for chronic leakage is surgery, but the authors report successful care with endoscopic septotomy.
