Glasgow prognostic score and body mass index predict short-term discontinuation of the antifibrotic agents pirfenidone and nintedanib.

Background: The antifibrotic agents pirfenidone and nintedanib have been shown to be effective in patients with idiopathic pulmonary fibrosis (IPF). However, discontinuation of antifibrotic drugs is a major clinical concern because of the lack of alternative treatment options. Therefore, we identified factors that may be useful for predicting the termination of antifibrotic agents.

Prognostic Significance of Preoperative Nutritional Assessment in Elderly Patients who Underwent Laparoscopic Gastrectomy for Stage I-III Gastric Cancer.

Background/aim: Surgery for elderly patients with gastric cancer is becoming more common. However, the risk factors of the laparoscopic surgery for these patients are unknown, and thus it is difficult to determine appropriate treatments for such patients. The aim of this retrospective study was to clarify the risk factors for the treatment outcomes after laparoscopic gastrectomy in elderly patients.

Quantitative CT analysis of interstitial pneumonia in anti-melanoma differentiation-associated gene 5 antibody-positive dermatomyositis: a single center, retrospective study.

Introduction: This study aimed to assess the utility of quantitative high-resolution computed tomography (HRCT) for determining the clinical course of anti-melanoma differentiation-associated gene 5 antibody-positive dermatomyositis-associated interstitial lung disease (MDA5 ILD).

Method: This study retrospectively analyzed the data of 34 patients with MDA5 ILD to determine the association between the clinical findings and extent of ILD via quantitative CT analysis at baseline and short-term follow-up. Quantified HRCT scores were evaluated as the lung severity score (LSS), percentage of opacity, and percentage of high opacity.

Indications for conversion hepatectomy for initially unresectable colorectal cancer with liver metastasis.

Purpose: Selected patients with initially unresectable colorectal cancer (CRC) and liver metastases undergo conversion surgery after appropriate chemotherapy. The prognosis of these patients is good, with some even cured of the disease. This retrospective, single-institution study analyzes the clinical importance of patient characteristics on the outcomes of conversion hepatectomy.

Health-related quality of life after esophagectomy in patients with esophageal cancer.

Esophageal cancer is one of the malignant tumors with the poorest prognosis. Esophagectomy, which is the mainstay of curative-intent treatments, imposes excessive surgical stress on the patients, and postoperative morbidity and mortality rates after esophagectomy remain high. On the other hand, the number of survivors after esophagectomy for esophageal cancer is increasing due to recent improvements in surgical techniques and multidisciplinary treatments for this cancer.

Comparison of laparoscopic surgery with open standard surgery for advanced gastric carcinoma in a single institute: a propensity score matching analysis.

Background: Compared with open standard gastrectomy (OG), laparoscopic gastrectomy (LG) did not result in inferior disease-free survival for early-stage and locally advanced gastric cancer (AGC). However, whether LG for AGC in elderly patients is more beneficial than OG is unclear.

Methods: This study examined 458 patients with AGC.

Interstitial lung disease with myeloperoxidase-antineutrophil cytoplasmic antibody-associated vasculitis in elderly patients.

Anti-neutrophil cytoplasmic antibodies-associated vasculitis (AAV) occurs in elderly people, and patients with anti-myeloperoxidase autoantibodies (MPO-ANCA)-positive AAV are often complicated with interstitial lung disease (ILD). This study aimed to evaluate the age-related clinical features of elderly patients with MPO-ANCA-positive AAV-ILD. This study retrospectively investigated 63 patients with MPO-ANCA-positive AAV-ILD, all of whom were 65 years or older at diagnosis.

Wireless Light-emitting Marker Using Magnetic Field Resonance for Laparoscopic Gastrointestinal Surgery.

Background: In laparoscopic gastrointestinal surgery, the location of the tumor is identified mainly with marking methods, such as ink tattooing and intraoperative gastrointestinal endoscopy and marking with a metal clip followed by confirmation with intraoperative x-ray fluoroscopy. Each method has disadvantages, such as complexity, instability of ink sticks, and radiation exposure. Thus, a simple and less-invasive marking method is needed.

[A Case of Advanced Rectal Cancer Successfully Treated with Preoperative Radiochemotherapy].

An 80-year-old woman who visited our hospital with chief complaints of decreased appetite and diarrhea. Lower gastrointestinal endoscopy showed a type 2 tumor in the rectal Ra, and biopsy revealed a well-differentiated adenocarcinoma. The patient had locally advanced rectal cancer with widespread contact with the sacrum, and preoperative radiochemotherapy (S-1 100 mg/day plus radiotherapy 50 Gy/25 Fr)was performed.

Dendritic Spine Density is Increased in Arcadlin-deleted Mouse Hippocampus.

The neural network undergoes remodeling in response to neural activity and interventions, such as antidepressants. Cell adhesion molecules that link pre- and post-synaptic membranes are responsible not only for the establishment of the neural circuitry, but also for the modulation of the strength of each synaptic connection. Among the various classes of synaptic cell adhesion molecules, a non-clustered protocadherin, Arcadlin/Paraxial protocadherin/Protocadherin-8 (Acad), is unique in that it is induced quickly in response to neural activity.

Laparoscopic Total Gastrectomy for Remnant Gastric Cancer: A Single-institution Experience and Systematic Literature Review.

Background/aim: The safety and efficacy of laparoscopic total gastrectomy (LTG) for remnant gastric cancer (RGC) remains unclear. The purpose of this study was to compare the clinical outcomes of LTG with open total gastrectomy (OTG) for RGC.

Patients And Methods: Twenty-two patients who underwent total gastrectomy for RGC were enrolled in this study.

Subtotal gastrectomy for gastric tube cancer using intraoperative indocyanine green fluorescence method.

Introduction: Currently, the frequency of evaluating the flow of a reconstructed gastric tube using indocyanine green (ICG) fluorescence has been increasing. However, it has been difficult to decide on the operation method for patients with gastric tube cancer (GTC). We herein report a case in which ICG was effective in a patient with resection of GTC.

[Radical Surgery Following Chemotherapy in a Patient with Mesenteric Recurrence Associated with Hematoma upon ESD for Rectal Cancer Three Years Six months Later].

A63 -year-old man complaining of anal pain visited our hospital. Three years 6 months previously, the patient underwent endoscopic submucosal dissection(ESD)for early-stage rectal cancer. Based on the pathological findings, adenocarcinoma with invasion to the submucosal layer(2,000 mm)and lymphovascular invasion were diagnosed.

[A Case of Small Cell Carcinoma of the Pancreas].

A 55-year-old man was admitted to our hospital for jaundice. Magnetic resonance cholangiopancreatography showed a mass in the pancreatic head as well as biliary obstruction. We strongly suspected invasive ductal carcinoma of the pancreas.

[A Clinical Study of Seven Cases of LECS for Gastric Submucosal Tumors].

Laparoscopy and endoscopy cooperative surgery(LECS)is a surgical technique to resect a tumor with minimal invasion, using both a laparoscope and endoscope. Twenty-eight surgeries for gastric submucosal tumors(SMT)were performed between 2009 and 2019. Seven of those cases were performed using LECS.

Serotonin induces Arcadlin in hippocampal neurons.

The monoamine hypothesis does not fully explain the delayed onset of recovery after antidepressant treatment or the mechanisms of recovery after electroconvulsive therapy (ECT). The common mechanism that operates both in ECT and monoaminergic treatment presumably involves molecules induced in both of these conditions. A spine density modulator, Arcadlin (Acad), the rat orthologue of human Protocadherin-8 (PCDH8) and of Xenopus and zebrafish Paraxial protocadherin (PAPC), is induced by both electroconvulsive seizure (ECS) and antidepressants; however, its cellular mechanism remains elusive.

[A Case of Small Bowel Perforation Due to Lung Cancer Metastasis].

A 79-year-old man was diagnosed with Stage ⅢB(T4N2M0)adenocarcinoma of the lung, administered. He suddenly developed abdominal pain with muscle guarding and rebound tenderness. An abdominal computed tomography scan revealed a thickened small bowel wall and mesenteric mass, as well as massive ascites and free air.

[A Case of Mesenteric Malignant Lymphoma Treated Using Single-Port Surgery and an Umbilical ZigZag Incision].

A 73 -year-old man was found to have a mesenteric tumor on abdominal ultrasonography and computed tomography (CT). Single-port laparoscopic surgery using an umbilical ZigZag incision was performed. Operative findings revealed that the tumor involved the mesentery.
