Peripheral Parenteral Nutrition Solutions and Bed Bath Towels as Risk Factors for Nosocomial Peripheral Venous Catheter-related Bloodstream Infection by .

In Japan, China, and Singapore, several studies have reported increased incidences of peripheral venous catheter-related bloodstream infection by during the summer. Therefore, we hypothesized that bed bathing with a -contaminated "clean" towels increases contact with the catheter and increases the odds of contaminating the peripheral parenteral nutrition (PPN). We found that 1) professionally laundered "clean" towels used in hospitals have (3.

A low prognostic nutritional index is associated with increased remote infections within 30 days of colorectal surgery: A retrospective cohort study.

Objective: This study aimed to identify risk factors for remote infection (RI) within 30 days after colorectal surgery.

Methods: This retrospective study included 660 patients who underwent colorectal surgery at Yamaguchi University Hospital or Ube Kosan Central Hospital between April 2015 and March 2019. Using electronic medical records, we identified the incidence of surgical site infection and RI within 30 days after surgery and obtained information on associated factors.

Cooperation between artificial intelligence and endoscopists for diagnosing invasion depth of early gastric cancer.

Background And Study Aims: The diagnostic ability of endoscopists to determine invasion depth of early gastric cancer is not favorable. We designed an artificial intelligence (AI) classifier for differentiating intramucosal and submucosal gastric cancers and examined it to establish a diagnostic method based on cooperation between AI and endoscopists.

Patients And Methods: We prepared 500 training images using cases of mainly depressed-type early gastric cancer from 250 intramucosal cancers and 250 submucosal cancers.

Establishment of a Screening Method for Epstein-Barr Virus-Associated Gastric Carcinoma by Droplet Digital PCR.

Background: Epstein-Barr virus-associated gastric carcinoma (EBVaGC) is classified as one of the molecular subtypes of gastric cancer. We used droplet digital polymerase chain reaction (ddPCR) to enable highly sensitive and quantitative detection of EBV.

Methods: EBV-DNA load was calculated based on the copy number of the BamH1-W fragment of EBV by ddPCR, and the cut-off value of EBV-DNA load was set.

Clinicopathologic Characteristics of Epstein-Barr Virus-Associated Gastric Cancer Over the Past Decade in Japan.

Epstein-Barr virus (EBV) is a ubiquitous human herpes virus, but related with several types of malignancies. Among EBV-related malignancies, EBV-associated gastric carcinoma (EBVaGC) has the largest patient's number. We screened for EBV infection in 1067 GC lesions of 1132 patients who underwent surgical resection from 2007 to 2017 in Japan and examined clinicopathological features of EBVaGC.

A case of postoperative recurrent cholangitis after pancreaticoduodenectomy successfully treated by tract conversion surgery.

A 69-year-old man, who had undergone pylorus-preserving pancreaticoduodenectomy (PD) (Imanaga procedure) for duodenum papilla cancer 13 years prior, had a history of repeated hospitalization due to cholangitis since the third year after surgery and liver abscess at the 10th year after surgery. Gastrointestinal series indicated no stenosis after the cholangiojejunostomy. However, reflux of contrast media into the bile duct and persistence of food residues were observed.

[Pancreatic and gastric metastases occurring a decade after nephrectomy for renal cell carcinoma].

We report the case of a 64-year-old man who underwent resection on two occasions for recurrent renal cell carcinoma. He first underwent right nephrectomy for renal cell carcinoma, and 10 years later, he underwent pylorus-preserving pancreaticoduodenectomy for pancreatic metastasis. Microscopic extracapsular invasion without lymph node metastasis was observed at that time.

Novel cell-free and concentrated ascites reinfusion therapy (KM-CART) for refractory ascites associated with cancerous peritonitis: its effect and future perspectives.

Background: We have actively carried out cell-free and concentrated ascites reinfusion therapy (CART) for refractory ascites. However, with conventional CART, the membrane becomes clogged after processing about 2 L of cancerous ascites fluid due to the fact that it is rich in cellular and mucous components; it is therefore difficult to process the entire volume of collected ascites.

Methods: We developed KM-CART which includes a membrane cleaning function, and applied it in 73 cases of cancerous ascites, after its basic functions had been evaluated in 11 cases of refractory cancerous ascites.

[Case of gastric cancer with recurrence of carcinomatous lymphangiosis of the lung 7.6 years after surgery and successfully treated with S-1/low-dose CDDP/Lentinan combination therapy].

A 78-year-old woman underwent gastrectomy for type 3 gastric cancer with pyloric stenosis, which was detected in November 1997. Thoracic and abdominal CT and other diagnostic procedures were conducted regularly for 5 years after surgery. The patient was recurrence-free and her clinical course was satisfactory.

En bloc resection for primary non-Hodgkin's lymphoma of the descending colon with massive extension into the neighboring organs.

A 79-year-old female who was surgically treated and received adjuvant chemotherapy for primary non-Hodgkin's lymphoma of the descending colon with massive extension into the pancreatic tail, spleen, and left kidney is herein reported. The patient had acute colonic obstruction and an urgent laparotomy was performed because endoscopic decompression using a transnasal ileus tube could not be done. We performed a left colectomy with an en bloc resection of the neighboring organs, followed by the creation of an end colostomy.

Pancreatic arteriovenous malformation treated by transcatheter embolization.

Arteriovenous malformation of the pancreas is a rare condition that may cause upper gastrointestinal bleeding. A 58-year-old man with an arteriovenous malformation of the pancreas is described. The patient had recurrent episodes of melena.
