Filter by:This study will be conducted in adult subjects diagnosed with any form of an advanced or metastatic solid tumors including urothelial carcinoma for which standard therapy is no longer effective or is intolerable. This is a phase 1, multi-center, open label study designed to assess safety and tolerability of IK-175 as a single agent and in combination with nivolumab, to determine the recommended phase 2 dose (RP2D). Disease response, pharmacokinetics (PK), pharmacodynamics, and response biomarkers will also be assessed.
In this study, the new aScope 4 Cysto is used to see if this new single use, flexible cystoscope performs as well as other routinely used flexible cystoscopes. This study will be done in patients who come to the clinic for either a diagnosis of their urethra and bladder or for a small intervention. For an intervention a lesion or tumor is resected, a stent in the ureter is taken out, or an injection in the bladder wall is given. The flexible cystoscope is passed into the urethra and bladder for visual inspection of the bladder and urethra. It will give information on how well the structures of the urinary tract and bladder can be viewed including any abnormalities that are present. If an intervention is performed the aScope 4 Cysto will be used with an endoscopic accessory.
Vesical Imaging-Reporting And Data System (VI-RADS) is proposed for predicting muscle invasive bladder cancer (MIBC) using multi-parametric MRI. However, No validation study on VI-RADS has been reported yet. Apparent diffusion coefficient (ADC) values on diffusion-weighted MRI are reportedly significantly lower in MIBC than those in non-MIBC(NMIBC).
NIRS technology is therefore a technique that exploits the different absorption properties of oxygenated and deoxygenated hemoglobin to evaluate the degree of tissue oxygenation. This hemodynamic response is measured in a completely non-invasive and silent manner, by the simple emission of light passing through different layers of biological tissue. In the literature, some studies concerning the use of the NIRS method for the study of urodynamics exist. They seem to show a correlation between the data of the urodynamic assessment and the data obtained with the NIRS method. Certain trends seem to be repeated with, for example, an increase in oxyhemoglobin at the beginning of the filling phase and the beginning of the urination phase. The aim of the study is to analyze the NIRS signal and find correlation with urodynamic data.
Radical cystectomy is associated with a greater risk of fracture due to long-term metabolic consequences of intestinal urinary diversions. One of the mechanisms theoretically involved with bone loss after radical cystectomy is metabolic acidosis that inhibits osteoblast activity, stimulates osteoclast bone resorption and urinary calcium loss. Other factors as advanced age, diabetes or chronic renal failure may increase the effect of metabolic acidosis. Moreover, osteoporosis in men remains under-diagnosed and under-appreciated. Although metabolic and bone changes after radical cystectomy are well known, bone mineral density (BMD) or fracture risk assessment are not recommended in different international guidelines during follow-up. The objective of this study is to evaluate the fracture risk of male patients undergoing radical cystectomy after more than one year of follow-up. Fracture risk assessment will be performed by BMD to analyse the prevalence of osteoporosis, vertebral fractures and measurement of Trabecular Bone Score (TBS) in combination with the Fracture Risk Assessment Tool (FRAX). These results will be correlated with blood markers with the objective to determine independent risk factors for osteoporosis or bone fracture in this population. To the best of the investigator's knowledge this will be the first study assessing the fracture risk after radical cystectomy performance evaluating BMD and the probability of fracture at 10 years using the FRAX algorithm.
Determine differences between lithogenic and non-lithogenic bile composition.
Evaluate MRI criteria for involvement of the posterior inferior wall of the bladder in patients with endometrial bladder disease.
The aim of this study is to determine the fall and balance conditions of Parkinson's patients according to their urinary complaints.
We try to assess the potential role of telomerase reverse transcriptase and MicroRNA (miR-155) in diagnosis of non-muscle-invasive bladder cancer and their correlation with stage and grade of the tumor.
Gall bladder status among children with chronic haemolytic anemia attending to Assuit University Children Hospital. Hemolysis is defined as the premature destruction of red blood cells (RBCs) (a shortened RBC life span). Anemia results when the rate of destruction exceeds the capacity of the marrow to produce RBCs. Normal RBC survival time is 110-120 days (half-life: 55-60 days), and thus, approximately 0.85% of the most senescent RBCs are removed and replaced each day. Patients with chronic haemolytic anemia are subjected to many complications of chronic haemolytic anemia e.g anemic heart failure, complications of blood transfusion as hepatitis and AIDS, hypersplenism, haemosiderosis ,among them there is incidence of gallbladder stone formation. This work aims to a) to determine the prevalence of gall bladder diseases among patient with chronic haemolytic anemia. b) to determine the risk factors of gall bladder diseases among patients with chronic haemolytic anemia.
