Background: FGFR2/3, MTAP and ERBB2 genomic alterations have treatment targets in advanced urothelial carcinoma (aUC). These alterations may affect tumor microenvironment and outcomes with immune checkpoint inhibitors (ICIs) in aUC.

Patients And Methods: We identified patients with available genomic data in our multi-institution cohort of patients with aUC treated with ICI.

Article Synopsis
  • The study investigated the effects of N-acetylcysteine (NAC) on testicular hypoxia caused by varicocele in mature Wistar rats, focusing on gene regulation related to apoptosis and oxidative stress.
  • Thirty-two rats were divided into four groups (Control, hypoxia, hypoxia treated with NAC, and healthy animals treated with NAC), with significant improvements in testicular health observed in the NAC-treated group after eight weeks.
  • Results showed that NAC increased antioxidant levels and reduced markers of oxidative stress, lowered apoptosis rates in germ cells, and improved histopathological parameters, indicating its potential as a protective treatment for testicular damage from hypoxia.

Enfortumab vedotin (EV) is used as monotherapy or combined with pembrolizumab in advanced urothelial carcinoma (aUC), but biomarker data associated with EV outcomes are limited. We identified 170 patients in the UNITE study who received EV monotherapy and had molecular biomarker data available. Outcomes for groups with and without a particular biomarker were compared using logistic regression (unadjusted) for the objective response rate (ORR), and a log-rank test and Cox proportional-hazard models (CPHMs) for progression-free survival (PFS) and overall survival (OS) from EV initiation.

A progressive kidney disease associated with inflammation and the immune system is called membrane glomerulonephritis (MGN). The present study investigatedthe combination of cyclosporine and fedratinib on Th17/regulatory T cells (Tregs) in rat models of MGN. Rats were given several doses of anti-Fx1A to induce MGN, and the resultant five groups of rats were fedratinib-cyclosporin receiving PHN rats, fedratinib, cyclosporin, and healthy rats.

Background: is a protozoan parasite responsible for canker in pigeons, a debilitating disease that causes significant economic losses. While metronidazole (MTZ) remains the primary treatment, the emergence of resistance is a growing concern. This study investigated the efficacy of eugenol and its nanoemulsion formulation against in both and settings.

  • Artificial insemination and semen cryopreservation have greatly enhanced cattle production, allowing top-breeding bull sperm to be used worldwide.
  • This study examined the impact of ferulic acid (FA) in various concentrations on frozen and thawed Simmental bull sperm, focusing on factors like motility and membrane functionality.
  • Results indicated that adding FA improved sperm quality and motility, with higher fertility rates seen in cows inseminated with FA concentrations of 0.25 and 0.35 mM compared to the control group.

During the freezing process of semen, due to the generating of significant amounts of free radicals, the quality of sperm changes. Epigallocatechin-3-gallate (EGCG) is a green tea catechin, which in this study was applied to investigate its effect on the quality of bulls' sperm. We collected semen samples with an artificial vagina from 12 Simmental bulls to evaluate the effect of EGCG (10.

Article Synopsis
  • - The study investigated the relationship between Tumor Mutational Burden (TMB) and Microsatellite Instability (MSI) status in patients with urothelial carcinoma (UC) receiving immune checkpoint inhibitors (ICI), focusing on overall survival (OS).
  • - Results showed that patients with a higher TMB (≥10 mut/Mb) generally experienced longer median OS compared to those with lower TMB, although these differences weren't always statistically significant.
  • - Notably, patients treated with maintenance avelumab had a significantly better OS when TMB was high (61 months vs. 17 months for low TMB), indicating potential benefits of ICI based on TMB and MSI status, warranting further investigation.

The progression and pathogenesis of membranous glomerulonephritis (MGN) are inextricably linked to chronic inflammation. Despite improving clinical remission rates due to the application of cyclophosphamide (CYC), treatment of MGN still requires further exploration. Ruxolitinib (Ruxo) negatively affects the signaling pathways participating in the production of pro-inflammatory cytokines.

Purpose: Lutetium-177 [Lu]Lu-PSMA-617 radioligand therapy (RLT) represents a significant advancement for metastatic castration-resistant prostate cancer (mCRPC), demonstrating improvements in radiographic progression free survival (rPFS) and overall survival (OS) with a low rate of associated side effects. Currently, most post-therapy SPECT/CT is conducted at 24 h after infusion. This study examines the clinical utility of a next-generation multi-detector Cadmium-Zinc-Telluride (CZT) SPECT/CT system (StarGuide) in same-day post-infusion assessment and early treatment response to [Lu]Lu-PSMA-617.

Background: Artificial insemination (AI) is one of the most important reproductive technologies used to modify animals genetically. Using this method, the genetic composition of the herd can be improved and selected by choosing bulls with excellent genetic characteristics. Taxifolin (TXF), a plant flavonoid, has shown an antioxidative effect.

Article Synopsis
  • This study investigates the impact of COVID-19 on female patients with breast cancer, particularly focusing on underrepresented racial/ethnic populations from March 2020 to June 2021 in the US.
  • The analysis included 1,383 patients, revealing that older age and certain racial/ethnic groups (such as Black and Asian American/Pacific Islanders) showed higher odds of severe COVID-19 outcomes.
  • Key findings noted that factors like worse performance status, pre-existing health conditions, and active cancer significantly contributed to increased severity, while variables like Hispanic ethnicity and anti-cancer therapy type did not impact outcomes as much.

Sperm survives for a very short time in fresh semen, and slow cooling to 5.00 ˚C kills a large number of sperms. This study was aimed to compare the semen quality parameters and anti-oxidant levels in four extenders (manual, Triladyl, Steridyl and AndroMed).

Background: Treatment options for penile squamous cell carcinoma are limited. We sought to investigate clinical outcomes and safety profiles of patients with penile squamous cell carcinoma receiving immune checkpoint inhibitors.

Methods: This retrospective study included patients with locally advanced or metastatic penile squamous cell carcinoma receiving immune checkpoint inhibitors between 2015 and 2022 across 24 centers in the United States, Europe, and Asia.

Background: Immune-related hepatitis (irH) is a serious immune-related adverse event (IRAE) that may result in morbidity, immune checkpoint inhibitor (ICI) therapy interruption and, rarely, mortality. The impact of underlying liver pathology, including liver metastasis, on the incidence of irH remains poorly understood.

Objectives: We hypothesized that the presence of underlying liver pathology increased the risk of irH in patients with cancer treated with ICI.

Genitourinary (GU) cancers including bladder, prostate, and kidney cancers affect older adults with a higher prevalence compared to younger adults. GU cancer treatment is associated with poorer outcomes in older adults compared to their younger counterparts. To better identify and support older adults receiving cancer care, oncologic societies recommend the use of a geriatric assessment (GA) to guide management.
