Introduction

  • Radical cystectomy with urinary diversion (C&D) is performed for patients with muscle-invasive bladder cancer (MIBC) or refractory carcinoma in situ (CIS)
  • C&D patients receive one of several types of diversion depending on their age, comorbidities, functional status, and extent of disease (Figure 1)
  • Post-operative length of stay (LOS) can be prolonged (9-11 days) and 30 day readmission rates and mortality elevated (30% and 1.5%); return of bowel function usually the rate-limiting step to discharge
  • Enhanced Recovery After Surgery (ERAS) protocols utilize pre-, intra-, and postoperative elements in order to improve return of bowel function and decrease LOS
  • Alvimopan is a μ-opioid receptor antagonist commonly included in ERAS, and limits deleterious effects of narcotics on the GI system
  • The goal of this analysis was to determine the effect of Alvimopan on post-operative LOS and 30 day readmission in patients undergoing C&D

Second-Harmonic Generation Microscopy Analysis Reveals Proteoglycan Decorin Is Necessary For Proper Collagen Organization In Prostate., Kirby R. Campbell, Rajeev Chaudhary, Monica Montano, Renato V. Iozzo, Wade A. Bushman, Paul J. Campagnola

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Collagen remodeling occurs in many prostate pathologies; however, the underlying structural architecture in both normal and diseased prostatic tissues is largely unexplored. Here, we use second-harmonic generation (SHG) microscopy to specifically probe the role of the proteoglycan decorin (Dcn) on collagen assembly in a wild type (wt) and Dcn null mouse (Dcn  -    /    -  ). Dcn is required for proper organization of collagen fibrils as it regulates size by forming an arch-like structure at the end of the fibril. We have utilized SHG metrics based on emission directionality (forward-backward ratio) and relative conversion efficiency, which are both related to the SHG coherence length ...


Examining The Relationship Between Urinary Pathogens, Antibiotic Exposure And Urolithiasis, Jennifer Bjazevic 2019 The University of Western Ontario

Examining The Relationship Between Urinary Pathogens, Antibiotic Exposure And Urolithiasis, Jennifer Bjazevic

Electronic Thesis and Dissertation Repository

Urinary stone disease is a highly prevalent urological condition; however, the pathophysiology remains poorly understood. Growing evidence suggests a relationship between urinary tract infections, antibiotic exposure and the development of urolithiasis. In this project, we utilized a dietary Drosophila melanogaster model and a calcium oxalate crystal adhesion assay to further investigate the impact of a urinary pathogen and antibiotics on calcium stone formation. We demonstrated that both a non-urease producing strain of Escherichia coli and the antibiotics, ciprofloxacin and trimethoprim-sulfamethoxazole, increased calcium stone formation. In addition, our preliminary work suggests that biomineralization agents such as osteopontin and zinc appear to ...

Reducing Catheter Associated Urinary Tract Infections (Cauti) By Decreasing Use Of Indwelling Catheters, Joanne Chapman, Brenda Clark, Brian Jumper, Carrie Strick

Maine Medical Center

Background:

Catheter Associated Urinary Tract Infections (CAUTI) are considered a preventable hospital-acquired infection [2]. Centers for Medicaid and Medicare no longer reimburse hospitals for preventable CAUTIs [2]. A concerted effort to decrease our indwelling urinary catheter (IUC) rate has led to a decrease in the number of infections related to these catheters at Maine Medical Center (MMC) in Portland, Maine. Starting in 2012 as a result of The Joint Commission National Patient Safety Goal, the inter-professional CAUTI committee focus has been on decreasing utilization of IUC[1]. After an initial large decrease in utilization, the rates have flattened. The effort ...

The human microbiota is paramount for normal host physiology. Altered host-microbiome interactions are part of the pathogenesis of numerous common ailments. Currently, much emphasis is placed on the involvement of the microbiome in the pathogenesis of type-2 diabetes mellitus (T2DM), impaired glucose tolerance, and other metabolic disorders (i.e. obesity). Several studies found highly significant correlations of specific intestinal bacteria with T2DM. A better understanding of the role of the microbiome in diabetes and its complications might provide new insights in the development of new therapeutic principles.

Our pilot study investigates the microbiota patterns in Romanian type-2 diabetic patients with ...

Improving Midstream Urine Collection For Urine Culture Through The Use Of A Novel Device, Flipcatch, Christopher Neely, Dante Varotsis, Helen Xu

Phase 1

Background : A midstream, clean-catch urine sample is the gold standard for diagnosing urinary tract infections and determining treatment. The current method of collection is not standardized, frustrating both patients and providers. The current method results in a high rate of contaminated samples (30-40%), which often need to be repeated in order to obtain a diagnosis and antibiotic susceptibility data. A design project was conducted in order to create a more effective urine collection device with the goals of decreasing contamination and improving patient and provider experience.

Methods : We conducted interviews of patients, allied health professionals, physicians, and clinical microbiologists involved ...

A Brief Review Of The Literature On The Malignant Ureteral Obstruction, Sorin Lupu, Adrian Brînză, Bogdan Socea, Dragos Marcu, Ileana Peride, Ana Maria Alexandra Stanescu, Tiberiu P. Neagu, Laurian Maxim

Journal of Mind and Medical Sciences

Malignant ureteral obstruction (MUO) caused by a primarily urological tumor or secondary to a late-stage malignancy can be difficult for the urologist to manage. Due to a lack of clinical data on the management of MUO, every case is particular and should be aborted individually.

Lack of specific treatment, either palliative or definitive, can severely damage renal function and lifetime expectancy in patients, causing even more damage that could otherwise be avoided.

Prompt management directed at the recovery of renal function is the main goal in such cases. Even after urinary flow is restored, life threatening post-obstructive diuresis needs to ...

Farhat Abbas

Abstract

BACKGROUND:

Granular cell tumors (GCTs) are extremely rare lesions of the urinary bladder with only nine cases being reported in world literature of which one was malignant. Generally believed to be of neural origin based on histochemical, immunohistochemical, and ultrastructural studies; they mostly follow a clinically benign course but are commonly mistaken for malignant tumors since they are solid looking, ulcerated tumors with ill-defined margins.

MATERIALS AND METHODS:

We herein report two cases of GCTs, one benign and one malignant, presenting with gross hematuria in a 14- and a 47-year-old female, respectively.

RESULTS:

Histopathology revealed characteristic GCTs with positive ...
