Early gastric cancer (EGC) with synchronous distant metastasis is extremely rare. N-Methyl-D-aspartic acid nmr Here, we report a case of stage IV Epstein-Barr virus (EBV) -associated EGC. A 51-year-old man presented with vague abdominal pain of 3 weeks' duration. Imaging studies revealed enlargement of the left supraclavicular, perigastric, and para-aortic lymph nodes, a huge gastric polypoid mass, and multiple liver masses. Histopathological examination of a biopsy specimen of the supraclavicular lymph node showed poorly differentiated carcinoma expressing EBV in tumor cell nuclei. The gastric mass exhibited tubular adenocarcinoma, which also expressed EBV in tumor cell nuclei. After 3 weeks of palliative chemotherapy with fluoropyrimidine and platinum, the patient died of liver failure. Next-generation sequencing analysis revealed mutation of the CDKN1B gene in the metastatic carcinoma and mutations of the CTNNB1 and PIK3R1 genes in the gastric carcinoma. In addition to the rare presentation of EBV-associated EGC, this case showed marked morphological and molecular differences between primary and metastatic tumors, which suggests clonal evolution of EBV-associated GC.

Surgical lung biopsy (SLB) is an important diagnostic tool for interstitial lung disease (ILD), yet the risk factors for SLB are still debatable and long-term outcomes remain unknown.

We retrospectively reviewed the records of 85 consecutive patients with ILD who underwent SLB by video-assisted thoracic surgery (VATS) from 2008 to 2019. Risk factors for complications and differences of outcomes between idiopathic pulmonary fibrosis (IPF) and other ILDs were examined.

All patients who underwent VATS had no mortality or acute exacerbation of ILD within 90 days of SLB. The rate of complication was 9.4%, and there were no statistically significant risk factors for complications. While the IPF group was not significantly different from the non-IPF group with regard to surgical parameters or complications, patients with IPF had significantly higher rates of mortality (50% vs. 9% in 5 years; p <0.001) and readmission due to acute exacerbation (75% vs. 8% in 5 years; p <0.001).

VATS lung biopsy for ILD can be a safe approach regardless of underlying phenotypes. An accurate diagnosis of IPF via SLB may be beneficial for correct patient management.

However, harvesting the right internal thoracic artery (RITA) under direct vision requires high surgical skill. We describe MICS CABG with the left internal thoracic artery (LITA) and a composite graft using the in situ right gastroepiploic artery (GEA) and radial artery (RA) to achieve complete coronary revascularization. No complications occurred, and postoperative computed tomography showed patency of all grafts. Our experience suggests that this composite graft can be used safely and effectively in MICS CABG for complete arterial revascularization without difficulty.Seventeen isolates of infectious bronchitis virus (IBV) were obtained from various prefectures of Japan during 2008-2019 and genetically analyzed. The IBV isolates were classified into six genetic groups, based on phylogenetic analysis of the S1 gene. The S1 genotypes were distinguishable by a newly developed restriction fragment length polymorphism (RFLP) method using three endonucleases, Hae II, Hpa I, and Fok I. Moreover, the isolates were classified into four genetic groups, based on phylogenetic analysis of the S2 gene. However, novel genetic groups based on a combination of S1 and S2 genotypes, which were undetected previously, were confirmed in this study, indicating that various recombinant IBV strains were prevalent in poultry in Japan.To date, little is known about the prognostic significance of ultrasonographic findings in dogs with protein-losing enteropathy (PLE). The aim of this retrospective study was to examine the prognostic value of ultrasonographic findings in dogs with PLE. A total of 26 dogs with PLE were included 20 dogs with chronic enteropathy and 6 dogs with gastrointestinal lymphoma. The presence of small intestinal dilatation was associated with shorter survival time in dogs with PLE (P=0.003). The presence of hyperechoic intestinal mucosal striations was associated with longer survival time in dogs with PLE (P=0.0085). The results of the current study indicate that the presence of small intestinal dilatation might be associated with poor prognosis in dogs with PLE.Pathogenic Escherichia coli is an important cause of diarrhea, edema disease, and septicemia in swine. In Japan, the volume of antimicrobial drugs used for animals is highest in swine, but information about the prevalence of antimicrobial-resistant bacteria is confined to apparently healthy animals. In the present study, we determined the O serogroups, virulence factors, and antimicrobial resistance of 360 E. coli isolates from swine that died of disease in Kagoshima Prefecture, Japan, between 1999 and 2017. The isolates of the predominant serogroups O139, OSB9, O149, O8, and O116 possessed virulence factor genes typically found in diarrheagenic E. coli. We further found five strains of third-generation cephalosporin-resistant E. coli that each produced an extended-spectrum β-lactamase encoded by blaCTX-M-14, blaCTX-M-15, blaCTX-M-24, blaCTX-M-61, or blaSHV-12. In 218 swine with a clear history of antimicrobial drug use, we further analyzed associations between the use of antimicrobials for the treatment of diseased swine and the isolation of resistant E. coli. We found significant associations between antimicrobial use and selection of resistance to the same class of antimicrobials, such as the use of ceftiofur and resistance to cefotaxime, cefazolin, or ampicillin, the use of aminoglycosides and resistance to streptomycin, and the use of phenicols and resistance to chloramphenicol. A significant association between antimicrobial use and the resistance of E. coli isolates to structurally unrelated antimicrobials, such as the use of ceftiofur and resistance to chloramphenicol, was also observed.
