Laparoscopic continent cutaneous urinary diversion using a modified Yang-Monti technique in an adult: A case report including 5-year follow-up.

Continuous cutaneous urinary diversion is challenging when the appendix is physically unavailable. The Yang-Monti channel is an alternative to the tunneled appendix for urinary diversion. We present a case involving a 49-year-old man who underwent total urethrectomy and cystostomy 10 months previously. No tumor recurrence was observed; however, the patient experienced severe catheter-related bladder irritation after the procedure. The patient was readmitted to the authors' hospital and underwent laparoscopic continent cutaneous urinary diversion using extracorporeal construction of a modified Yang-Monti channel. The operation lasted 232 minutes, with an estimated blood loss of 10 mL. The patient was discharged from hospital 6 days after surgery and removal of the cystostomy tube. After this, clean intermittent catheterization was performed every 3 hours for 4 weeks. Five years after the procedure, the modified Yang-Monti channel was still used for clean intermittent catheterization without any stomal stenosis being observed. The patient was satisfied with his postoperative quality of life.

Global population structure and genomic surveillance framework of carbapenem-resistant Salmonella enterica.

Due to the frequent international and intercontinental transmission of multidrug-resistant bacteria, it is imperative to understand the epidemiology, phylogeography, and population structure of carbapenem-resistant Salmonella enterica (CRSE) across the globe. During the period of 2015-2022, two blaNDM-carrying S. enterica strains were recovered from 3695 Salmonella strains in four hospitals in China. The global phylogenetic framework and geographical distribution of CRSE were defined by our recently updated bacterial whole genome sequence typing and source tracking database BacWGSTdb 2.0 to measure the diversity and evolutionary relatedness in context with epidemiological metadata. Phylogeny for all carbapenemase gene-harboring plasmids in S. enterica based on the pairwise Mash differences was also constructed to evaluate the potential transmission of these plasmids in a global context. A large-scale phylogenetic analysis grouped global CRSE into nine distinct clades. The small genetic distance (< 20 SNPs) between 198 pairs of CRSE suggested the presence of clonal transmission. Global CRSE have significant geographical variations, which was associated with the clonal lineages and carbapenemase genes. Carbapenemase gene-carrying plasmids with a high degree of similarity have surfaced in various hosts and countries. The widespread of multiple-replicon plasmids that offer a great capacity to accommodate multiple antimicrobial resistance genes is continuously enhancing the potential risk of CRSE isolates to propagate globally. Both clonal spread of strains and horizontal transfer of carbapenemase gene-harboring plasmids contribute to the global dissemination of CRSE. Our findings on the worldwide spread and transmission dynamics of this emerging bacterium has increased the knowledge of its global epidemics. Continued epidemiological surveillance is necessary to prevent global outbreak of multidrug-resistant Salmonella infections.

Comprehensive Analysis of the Expression, Prognosis, and Biological Significance of OVOLs in Breast Cancer.

BACKGROUND: The study aimed to investigate the expression of OVOLs in breast cancer (BRCA) tissues and their value in prognosis. METHODS: ONCOMINE was used to analyze the expressions of OVOL1, OVOL2, and OVOL3 mRNA between BRCA tissues and normal breast tissues. The Wilcoxon rank sum test and t-test were used to assess the expression of OVOLs between BRCA tissues and unpaired/paired normal breast tissues. GEPIA and ROC curves were used to analyze the relationship between OVOLs expression and clinical pathological stage. Kaplan-Meier plotter was used to analyze prognosis. cBioPortal was used to analyze the mutation of OVOLs. GEPIA was used to analyze the co-expression of OVOLs. GO and KEGG analyses were performed by the DAVID software to predict the function of OVOLs co-expression genes. RESULTS: The expression of OVOL1/2 was significantly higher in BRCA tissues than in normal breast tissues. The OVOL3 expression correlated with tumor stage. The AUC of OVOLs was 0.757, 0.754, and 0.537, respectively. OVOL1 high expression was associated with shorter overall survival (HR: 1.48; 95% CI: 1.07-2.04; P=0.018). The OVOLs were associated with pathways including axon guidance, thyroid hormone signaling pathway, and ubiquinone and other terpenoid-quinone biosynthesis. CONCLUSION: OVOL1 is a new potential marker of prognosis in BRCA, and OVOL1/2 are potential therapeutic targets in BRCA.

Knockdown of sterol O-acyltransferase 1 (SOAT1) suppresses SCD1-mediated lipogenesis and cancer procession in prostate cancer.

Prostate cancer (PCa) is one of the most fatal malignant tumors that occurs in the prostate epithelium, especially in older men, the mortality of which ranks sixth among all cancer-related deaths. It has been urgently needed to elucidate the pathogenesis of PCa and provide promising therapeutic targets for PCa treatment. The Sterol O-acyltransferase 1 (SOAT1), cholesterol metabolism enzyme, was widely expressed in various cancer tissues, resulting in cancer progression. SOAT1 has been demonstrated to be highly expressed in prostate cancer tissues, whereas the underlying mechanism has not been elucidated. Herein, we found the expression of SOAT1 was elevated in human PCa tissues, which demonstrated SOAT1 level was correlated with lymph node metastasis (p = 0.006), clinical stage (p = 0.032), grading (p = 0.036), and Gleason score (p = 0.030) of PCa patients. In addition, we revealed that SOAT1 promoted proliferation and liposynthesis of PCa cells by targeting Stearoyl-CoA Desaturase 1 (SCD1). Our data further confirmed that SCD1 overexpression reversed the proliferation and liposynthesis defects caused by SOAT1 depletion in PCa cells, however, SOAT1 depletion inhibited tumor growth of PCa cells in mice. We further found SOAT1 contributed to the progression of PCa via SREBF1 pathway. Taken together, our data revealed the mechanism underlying SOAT1 promoting PCa progression in vitro and in vivo.
