Abstract Currently, the decision of aortic valve replacement surgery time for asymptomatic patients with moderate-to-severe aortic stenosis (AS) is made by healthcare professionals based on the patient’s clinical biometric records. A delay in surgical aortic valve replacement (SAVR) can potentially affect patients’ quality of life. By using ML algorithms, this study aims to predict the optimal SAVR timing and determine the enhancement in moderate-to-severe AS patient survival following surgery. This study represents a novel approach that has the potential to improve decision-making and, ultimately, improve patient outcomes. We analyze data from 176 patients with moderate-to-severe aortic… More >

Abstract The Corona (COVID-19) epidemic has triggered interest in many fields of technology, medicine, science, and politics. Most of the mathematical research in this area focused on analyzing the dynamics of the spread of the virus. In this article, after a review of some current methodologies, a non-linear system of differential equations is developed to model the spread of COVID-19. In order to consider a wide spectrum of scenarios, we propose a susceptible-exposed-infected-quarantined-recovered (SEIQRS)-model which was analyzed to determine threshold conditions for its stability, and the number of infected cases that is an infected person will… More >

Abstract COVID-19 is one of the most highly infectious diseases ever emerged and caused by newly discovered severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has already led the entire world to health and economic crisis. It has invaded the whole universe all most every way. The present study demonstrates with a nine mutually exclusive compartmental model on transmission dynamics of this pandemic disease (COVID-19), with special focus on the transmissibility of symptomatic and asymptomatic infection from susceptible individuals. Herein, the compartmental model has been investigated with mathematical analysis and computer simulations in order to understand… More >

Abstract Introduction: In the pediatric Appropriate Use Criteria (AUC), abnormal electrocardiogram (ECG) in an asymptomatic patient has been rated as an “Appropriate” indication for transthoracic echocardiogram (TTE). We hypothesized that the yield of abnormal findings on TTE for this indication will be low.
Methods: All asymptomatic patients (≤ 18 years) from January 1, 2015 to December 31, 2017 who underwent initial outpatient evaluation at our center and had a TTE ordered for an abnormal ECG, were included. Clinic records were reviewed to obtain ECG and TTE findings.
Results: Of the 199 study patients, 13 (6.5%) had abnormal findings. Incomplete… More >

Abstract Asymptomatic microscopic and gross hematuria are common problems for the primary care physician. The exact defi nition of microscopic hematuria is debated, but is defi ned by one group as > 3 red blood cells/high power microscopic fi eld. While the causes of hematuria are extensive, the most common differential diagnosis for both microscopic and gross hematuria in adults includes infection, malignancy, and urolithiasis. Clinical evaluation of these patients often involves urological consultation with urine cytology, urine culture, imaging studies, and cystoscopy. Patients who have no identifi able cause after an extensive workup should be More >

Abstract Objectives: To evaluate the feasibility and safety of robot-assisted laparoscopic partial cystectomy for the treatment of rectal and bladder endometriosis.
Materials and methods: A 23-year-old female with history of infertility and pelvic pain was found to have a 4 cm bladder mass and rectal nodule on pelvic ultrasonography. Patient denied any other genitourinary symptoms. Cystoscopy and bladder mass biopsy revealed endometriosis. After failure to suppressive hormonal medical therapy a partial cystectomy and resection of a rectal lesion was performed with robotic assistance (da Vinci). The procedure included excision of an ovarian cyst and several peritoneal endometrioid implants.

Abstract Background: Patients with advanced prostate cancer eventually cease to respond to hormonal therapy and thus progress to hormone refractory prostate cancer (HRPC). Prednisone has been used in this setting; however, limited data is available for this monotherapy in the asymptomatic HRPC population.
Objective: To evaluate the PSA response rate to prednisone in asymptomatic patients with hormone refractory prostate cancer (HRPC). Secondary objectives were to determine toxicity, predictors of response, and to determine overall survival of this population.
Methods: Patients with asymptomatic HRPC that were treated with low dose prednisone from April 1998 to 2003 were identified from the… More >

Abstract Introduction: Many urologists endorse the concept of screening asymptomatic siblings of children known to have vesicoureteral reflux. Others oppose screening until there is better evidence to justify the cost and potential morbidity of adopting a widespread screening program.
Methods: A literature review of the following topics was carried out: 1) screening programs in general; 2) reflux in general; 3) familial reflux; and 4) screening for familial reflux.
Results: The evidence supporting our traditional surgical and medical management strategies for reflux is weak. The evidence supporting screening is lacking. Public Health organizations do not address the issue of screening… More >
