Repurposing of Metformin to Improve Survival Outcomes in Patients With Upper Tract Urothelial Carcinoma.

Purpose: Upper tract urothelial carcinoma (UTUC) presents a higher incidence rate in Taiwan compared to Western societies. The aim of this study is to investigate the potential of metformin in improving survival outcomes for patients with UTUC in Taiwan.

Material And Methods: This retrospective study included 940 patients with UTUC and type 2 diabetes from the Taiwan UTUC Collaboration Group, spanning 21 hospitals from July 1988 to September 2023.

Effects of pre-experimental fasting and sheltering on the swimming performance and oxygen consumption of juvenile grass carp (Ctenopharyngodon idella).

This study investigated the effects of pre-experimental fasting for 2, 7, and 14 days under both unsheltered (12 h dark-12 h light) and sheltered conditions on the critical swimming speed (U) and oxygen consumption (MO) of juvenile grass carp, using a modified swim respirometer. Key findings include (1) the U of test fish decreased significantly, by 28%, after fasting for 14 days and sheltering intensified the impact to a 43% decrease, and (2) fish anaerobic capacity decreased after 7 days but increased after 14 days, and was enhanced by sheltering conditions. These findings are important as they indicate that fasting and sheltering can impair grass carp survival and disrupt river ecosystem balance, highlighting the need for habitat conservation.

Background: The clinical benefit of preoperative oral nutritional supplements (ONS) in patients undergoing surgery for gastrointestinal cancer remains controversial.

Objective: To evaluate the effect of preoperative ONS on postoperative clinical outcomes in patients with gastrointestinal cancer.

Methods: We searched PubMed, EMBASE, Web of Science, Cochrane Library, Scopus, and the Chinese National Knowledge Infrastructure databases for randomized controlled trials evaluating preoperative ONS in patients undergoing surgery for gastrointestinal cancer from inception until April 2024.

No difference in oncological outcomes and perioperative complications between patients with ESRD with unilateral and bilateral UTUC receiving radical nephroureterectomy.

Patients with end stage renal disease (ESRD) are at high risk of developing upper tract urothelial carcinoma (UTUC). Due to high recurrence rate of UTUC in contralateral kidney and ureter, and high risk of complications related to surgery and anesthesia, whether it's necessary to remove both kineys and ureters at one time remains in debate. We utilized Taiwanese UTUC Registry Database to valuate the difference of oncological outcomes and perioperative complications between patients with ESRD with unilateral and bilateral UTUC receiving surgical resection.

New infundibulopelvic angle measurement method can predict stone-free rates following retrograde intrarenal surgery.

To enhance the accuracy of predicting stone-free rates after retrograde intrarenal surgery, we devised a novel approach to assess the renal infundibulopelvic angle. We conducted a retrospective review of patient records for those who underwent retrograde intrarenal surgery for renal stones between April 2018 and August 2019. Patient demographics, stone characteristics, and perioperative data were recorded.

NTRK3 exhibits a pro-oncogenic function in upper tract urothelial carcinomas.

Neurotrophic receptor tyrosine kinase 3 (NTRK3) has pleiotropic functions: it acts not only as an oncogene in breast and gastric cancers but also as a dependence receptor in tumor suppressor genes in colon cancer and neuroblastomas. However, the role of NTRK3 in upper tract urothelial carcinoma (UTUC) is not well documented. This study investigated the association between NTRK3 expression and outcomes in UTUC patients and validated the results in tests on UTUC cell lines.

Lipid Profiles Impact on the Oncologic Outcome of Upper Tract Urothelial Carcinoma.

Background: The prognosis of upper tract urothelial carcinoma (UTUC) varies, with T3/T4 UTUC having less than 50% 5-year survival post-radical nephroureterectomy (RNU). Lipid profiles including cholesterol (CHOL), low-density lipoprotein (LDL), and triglycerides (TGs), and high-density lipoprotein (HDL) have shown correlations with oncologic outcomes in various cancers. We aimed to investigate the prognostic significance of the lipid profiles in UTUC patients who had received RNU.

[Occurrence Characteristics of Microplastics in Multi-environmental Media and of Manao River].

Microplastic pollution poses threats to aquatic ecosystems and human health. In this study, in order to investigate the characteristics of microplastic occurrence in different environmental media, the abundance, particle size, shape, color, and composition types of microplastics in the water column, sediment, riparian zone soil, and the benthic snail of the Manao River were analyzed using field sampling, microscopic observation, and Fourier infrared spectroscopy. The results showed that the average abundance of microplastics in the surface water of the Manao River was (5.

[Assessment of Microplastic Pollution and Estimation of Annual Emission Volume in the Dongshan Canal of Yichang City].

Microplastics, as an emerging pollutant, have garnered global attention. Urban areas are key hotspots for the generation of microplastic pollution, whereas urban water bodies act as vital conduits for the dissemination of microplastics to other freshwater environments. In this study, the Dongshan Canal in the urban area of Yichang City was selected as the research subject.

Genetically Encoded Lizard Color Divergence for Camouflage and Thermoregulation.

Local adaptation is critical in speciation and evolution, yet comprehensive studies on proximate and ultimate causes of local adaptation are generally scarce. Here, we integrated field ecological experiments, genome sequencing, and genetic verification to demonstrate both driving forces and molecular mechanisms governing local adaptation of body coloration in a lizard from the Qinghai-Tibet Plateau. We found dark lizards from the cold meadow population had lower spectrum reflectance but higher melanin contents than light counterparts from the warm dune population.

Prognostic factors of intravesical recurrence after radical nephroureterectomy for upper tract urothelial carcinoma.

MicroRNA-299-3p inhibits cell proliferation, motility, invasion and angiogenesis via VEGFA in upper tract urothelial carcinoma.

Background: Upper tract urothelial carcinoma (UTUC) is a rare tumor with extraordinarily different features between Eastern and Western countries. Vascular endothelial growth factor-A (VEGFA) was originally identified as a secreted signaling protein and regulator of vascular development and cancer progression. In this study, we aimed to elucidate the molecular mechanisms underlying the regulation of VEGFA by microRNA in UTUC.

Downregulation of CRTAC1 in Urothelial Carcinoma Promotes Tumor Aggressiveness and Confers Poor Prognosis.

Background: Cartilage acidic protein 1 (CRTAC1) is a glycosylated calcium-binding extracellular matrix protein. The oncological functions of CRTAC1 in urothelial carcinoma (UC) of the urinary bladder (UB) and upper urinary tract (UT) have not yet been elucidated. Based on the published UBUC transcriptome data, we re-evaluated the differential expression profile of calcium ion binding-related genes (GO:0005509), and we found that was the most significantly downregulated gene in UBUC progression.

The phased telomere-to-telomere reference genome of Musa acuminata, a main contributor to banana cultivars.

Musa acuminata is a main wild contributor to banana cultivars. Here, we reported a haplotype-resolved and telomere-to-telomere reference genome of M. acuminata by incorporating PacBio HiFi reads, Nanopore ultra-long reads, and Hi-C data.

Telomere-to-telomere haplotype-resolved reference genome reveals subgenome divergence and disease resistance in triploid Cavendish banana.

Banana is one of the most important crops of the world. Cavendish-type bananas, which have a monospecific origin (AAA), account for around half of the global banana production, thereby are of great significance for human societies. However, until now, the high-quality haplotype-resolved reference genome was still undecoded for banana cultivars.

Upregulation of dihydropyrimidinase-like 3 (DPYSL3) protein predicts poor prognosis in urothelial carcinoma.

Background: Dihydropyrimidinase-like 3 (DPYSL3) is a cytosolic phosphoprotein expressed in the nervous system and is crucial for neurogenesis. A previous study showed that increased DPYSL3 expression promotes tumour aggressiveness in pancreatic ductal adenocarcinoma, gastric cancer, and colon cancer. However, the role of DPYSL3 in affecting the biological behaviour of urothelial carcinoma (UC) is not yet understood.

Preoperative hydronephrosis is an independent protective factor of renal function decline after nephroureterectomy for upper tract urothelial carcinoma.

Objectives: To evaluate the predictive role of pre-nephroureterectomy (NU) hydronephrosis on post-NU renal function (RF) change and preserved eligibility rate for adjuvant therapy in patients with upper tract urothelial carcinoma (UTUC).

Patients And Methods: This retrospective study collected data of 1018 patients from the Taiwan UTUC Collaboration Group registry of 26 institutions. The patients were divided into two groups based on the absence or presence of pre-NU hydronephrosis.

Development of Deep Learning with RDA U-Net Network for Bladder Cancer Segmentation.

In today's high-order health examination, imaging examination accounts for a large proportion. Computed tomography (CT), which can detect the whole body, uses X-rays to penetrate the human body to obtain images. Its presentation is a high-resolution black-and-white image composed of gray scales.

Cumulative sum analysis of the learning curve of laparoendoscopic single-site robot-assisted radical prostatectomy.

Background: Radical prostatectomy has become the gold standard for treating localized prostate cancer. Improvement in the single-site technique and surgeon's skill reduces not only the hospital duration but also the number of wounds. Realizing the learning curve for a new procedure can prevent unnecessary mistakes.

Herpes Zoster Risk in Patients with Rheumatoid Arthritis and Its Association with Medications Used.

Rheumatoid arthritis (RA) was associated with the risk of incident herpes zoster (HZ), which might be influenced by medication use by RA patients. We aimed to investigate the association of RA with the risk of incident HZ and how the HZ risk effected by RA medications in CIC RA patients. We conducted an observational study including population-based representative insurance claims data of 19,673 patients with RA and 39,346 matched patients without RA during 1997-2010 from the Taiwan National Health Insurance Research Database; we identified 1651 patients with catastrophic illness-certified (CIC) RA and 11,557 matched patients with non-CIC RA.

Assessment of the Association of Vitamin D and the Risk of Tuberculosis among End-Stage Kidney Disease Population.

We investigated the role of vitamin D in the risk of tuberculosis (TB) among patients with end-stage kidney disease (ESKD). The retrospective cohort was conducted with data of 20,985 patients with kidney disease and 20,985 controls without kidney disease (1:1 matching on age of cohort entry and sex) in the duration of 1997−2010 from the Taiwan National Health insurance database. Then, by a case−cohort study, among 20,985 kidney disease, 3194 ESKD patients were identified with matched 3194 non-ESKD patients.
