Quality-of-Life Outcomes in Female Patients With Ileal Conduit or Orthotopic Neobladder Urinary Diversion: 6-Month Results of a Multicenter Prospecti…

2022

Radical cystectomy (RC) often affects patients’ life as this surgery is a traumatic and invasive event for the patients, with drawbacks on their daily, social, working, and sex life. Such changes in the quality of life (QoL) of patients are commonly studied through retrospective clinical evaluations and rarely with longitudinal studies. To date, studies focusing on functional outcomes, sexual function, and health-related QoL for female patients are lacking. We evaluated 37 patients using EORTC QLQ-C30 (QLQ-30) and Short-Form 36 (SF-36) questionnaires, before and after surgery, at 3 and 6 months of follow-up. The mean values for the emotional functioning in QLQ-C30 as well as the mental heal…

The Odd Sibling: Features ofβ3-Adrenoceptor Pharmacology

2014

beta(3)-Adrenoceptor agonists have recently been introduced for the treatment of overactive urinary bladder syndrome. Their target, the beta(3)-adrenoceptor, was discovered much later than beta(1)- and beta(2)-adrenoceptors and exhibits unique properties which make extrapolation of findings from the other two subtypes difficult and the beta(3)-adrenoceptor a less-understood subtype. This article discusses three aspects of beta(3)-adrenoceptor pharmacology. First, the ligand-recognition profile of beta(3)-adrenoceptors differs considerably from that of the other two subtypes, i.e., many antagonists considered as nonselective actually are beta(3)-sparing, including propranolol or nadolol. Man…

Validation of Neutrophil-to-lymphocyte Ratio in a Multi-institutional Cohort of Patients With T1G3 Non–muscle-invasive Bladder Cancer

2018

The aim of this multicenter study was to investigate the prognostic role of neutrophil-to-lymphocyte ratio (NLR) and to validate the NLR cutoff of 3 in a large multi-institutional cohort of patients with primary T1 HG/G3 non-muscle-invasive bladder cancer (NMIBC).

LOCAL MICROWAVE HYPERTHERMIA AND INTRAVESICAL CHEMOTHERAPY AS BLADDER SPARING TREATMENT FOR SELECT MULTIFOCAL AND UNRESECTABLE SUPERFICIAL BLADDER TU…

1998

Purpose: The role of a combined regimen of local hyperthermia and topical chemotherapy in patients with multifocal and recurrent superficial bladder tumors not curable by transurethral resection was evaluated in a neodjuvant organ sparing clinical study. Materials and Methods: A total of 19 patients with multifocal, superficial grades 1 to 3 bladder tumors that recurred after intravesical chemoprophylaxis or immunoprophylaxis underwent local combined administration of microwave induced hyperthermia and intravesical chemotherapy as a debulking approach. Due to extensive superficial involvement of the bladder walls complete transurethral resection of all tumors seemed technically unfeasible i…

Microwave-Induced Hyperthermia and Cytostatic Agent for Superficial Bladder Cancer

2005

The efficacy and local toxicity of the intravesical combination of microwave-induced hyperthermia with a cytostatic agent in patients affected by superficial bladder cancer is presented. Between 1994 and 2002, two studies were performed on ablative and adjuvant intravesical thermo-chemotherapy. The ablative study demonstrated complete tumor eradication in 88% of patients who should have undergone cystectomy due to diffuse multiple papillary tumors non-responsive TUR and intravescical adjuvant therapy. In a randomized study, comparing adjuvant thermo-chemotherapy vs. standard chemotherapy with mitomycin C, recurrence-free survival analysis at 24 months revealed a significant difference in f…

Keyhole limpet hemocyanin (KLH): a biomedical review

1999

In this review we present a broad survey of fundamental scientific and medically applied studies on keyhole limpet hemocyanin (KLH). Commencing with the biochemistry of KLH, information on the biosynthesis and biological role of this copper-containing respiratory protein in the marine gastropod Megathura crenulata is provided. The established methods for the purification of the two isoforms of KLH (KLH1 and KLH2) are then covered, followed by detailed accounts of the molecular mass determination, functional unit (FU) structure, carbohydrate content, immunological analysis and recent aspects of the molecular genetics of KLH. The transmission electron microscope (TEM) has contributed signific…

Induction of cholesterol biosynthesis by archazolid B in T24 bladder cancer cells.

2014

Abstract Background Resistance of cancer cells towards chemotherapeutics represents a major cause of therapy failure. The objective of our study was to evaluate cellular defense strategies in response to the novel vacuolar H+-ATPase inhibitor, archazolid B. Experimental approach: The effects of archazolid B on T24 bladder carcinoma cells were investigated by combining “omics” technologies (transcriptomics (mRNA and miRNA) and proteomics). Free cholesterol distribution was determined by filipin staining using flow cytometry and fluorescence microscopy. Flow cytometry was performed for LDLR surface expression studies. Uptake of LDL cholesterol was visualized by confocal microscopy. SREBP acti…

Role of Neutral Amino Acid Transport and Protein Breakdown for Substrate Supply of Nitric Oxide Synthase in Human Endothelial Cells

2003

Endothelial dysfunction is often associated with a relative substrate deficiency of the endothelial nitric oxide synthase (eNOS) in spite of apparently high intracellular arginine concentrations. For a better understanding of the underlying pathophysiological mechanisms, we aimed to characterize the intracellular arginine sources of eNOS. Our previous studies in human endothelial EA.hy926 cells suggested the existence of two arginine pools: pool I can be depleted by extracellular lysine, whereas pool II is not freely exchangeable with the extracellular space, but accessible to eNOS. In this study, we demonstrate that the eNOS accessible pool II is also present in human umbilical vein endoth…

Trattamento endovescicale alternativo al BCG nel carcinoma vescicale NMI a rischio intermedio o elevato

2013

Endovesical treatment as an alternative to BCG for intermediate or high-risk NMI bladder cancer A shortage of BCG is foreseen till the end of 2013. Which will be the management of intermediate and high-risk NMI-BC if BCG will not be available? In patients harboring high-risk NMI tumors, particularly T1G3 and Tis, the first therapeutic choice is radical cystectomy. Device-assisted therapies, although showing promising results, should be considered only for selected patients. In intermediate risk patients, intravesical chemotherapy remains a legitimate option even if BCG is available. Thus, in a period of BCG shortage, intravesical chemotherapy should be offered, preferably preceded by early …
