Article Synopsis
  • This study investigated the effects of different irrigation setups and ureteral access sheath sizes on intrarenal pressure during flexible ureteroscopy in pigs.
  • Utilizing anesthetized female pigs and a flexible ureteroscope that recorded pressure, the researchers performed procedures with varying irrigation methods (gravity vs. manual pumping) and UAS sizes (11/13 and 12/14).
  • Results showed significantly lower intrarenal pressure with the use of UAS and under various irrigation methods, indicating the potential for improved surgical outcomes through real-time pressure monitoring during ureteroscopy.

Inflatable penile prosthesis (IPP) surgery is an effective treatment for erectile dysfunction (ED), but infections pose a significant threat to its success. Current guidelines lack antifungal recommendations, despite rising fungal infection rates post-IPP surgery. This review examines epidemiology, risk factors (including diabetes mellitus, immunosuppression, and obesity), and pathogenesis, highlighting the role of biofilm formation in device contamination.

Article Synopsis
  • The study aimed to assess the learning curve for four basic surgical skills in both laparoscopic and robotic surgeries using the avatera® system.
  • Participants, who had no prior experience, practiced tasks after watching educational materials and undergoing 2-hour training, with their performance times measured across multiple attempts.
  • Results showed that practice significantly reduced completion times, and prior laparoscopic experience enhanced training efficiency, indicating that robotic skills can be learned more quickly than laparoscopic ones.

Article Synopsis
  • The study assesses the safety and feasibility of the Florence robotic intracorporeal neobladder technique during laparoscopic radical cystectomy in patients with muscle-invasive bladder cancer.
  • All surgeries were completed successfully with a median operative time of 343 minutes, no intraoperative complications, and a hospital stay averaging 7 days, demonstrating effective short-term outcomes.
  • While some patients experienced minor complications, the overall results indicate that this technique is promising, but further large-scale prospective studies are needed to confirm long-term effectiveness.

The emerging Internet of Things (IoTs) and cloud technologies spark dramatic growth in efficiency and productivity for the conventional e-health sector. However, the extensive applications of the communication network also expose the sensitive medical data to the unprecedented cyber threats. To protect the data privacy in IoTs-based e-health cloud environments, we propose an adaptively secure data sharing scheme with traceability and equality test (T-ABEET).

Objective: To evaluate the transfer of the practical skills of robot-assisted surgery acquired in the dry-lab into a real live experimental setting for performing upper and lower urinary tract surgeries.

Material And Methods: An in vivo experimental study design was utilized. Six urology trainees and fellows; two 2nd year trainees with no previous exposure to laparoscopic surgery (Group 1), two 4th year residents with medium exposure to laparoscopic surgery (Group 2) and two fellows trained to perform laparoscopic surgeries (Group 3) performed ureteral reimplantation into the bladder, pyeloplasty, and radical nephrectomy on three female pigs under general anesthesia.

Purpose: To investigate the feasibility of the avatera system for performing robot-assisted radical cystectomy (RARC) followed by intracorporeal reconstruction of ileal neobladder.

Methods: Six anesthetized female pigs were used to perform RARC and formation of the intracorporeal orthotopic ileal neobladder. Three surgeons with different level of expertise in the use of robotic systems performed RARC after a short instructional lecture and a 2-h hands-on training.

Incorporating pigments into polymers can be done for various purposes, including the introduction of color, interfacial effects, or aesthetics. If these pigments are to disperse properly, then the process of extrusion must be optimized. During polymer compounding extrusion, three effective processing factors were investigated: feed rate (FR), speed (Sp.

The classification of medical images is significant among researchers and physicians for the early identification and clinical treatment of many disorders. Though, traditional classifiers require more time and effort for feature extraction and reduction from images. To overcome this problem, there is a need for a new deep learning method known as Convolution Neural Network (CNN), which shows the high performance and self-learning capabilities.

Governments of the world have invested a lot of manpower and material resources to combat COVID-19 this year. At this moment, the most efficient way that could stop the epidemic is to leverage the contact tracing system to monitor people's daily contact information and isolate the close contacts of COVID-19. However, the contact tracing data usually contains people's sensitive information that they do not want to share with the contact tracing system and government.

A significant percentage of security research that is conducted suffers from common issues that prevent wide-scale adoption. Common snags of such proposed methods tend to include (i) introduction of additional nodes within the communication architecture, breaking the simplicity of the typical client-server model, or fundamental restructuring of the Internet ecosystem; (ii) significant inflation of responsibilities or duties for the user and/or server operator; and (iii) adding increased risks surrounding sensitive data during the authentication process. Many schemes seek to prevent brute-forcing attacks; they often ignore either partially or holistically the dangers of other cyber-attacks such as MiTM or replay attacks.

Background: Studies using 1 mg of colchicine to prevent postoperative atrial fibrillation (POAF) reported conflicting results. Moreover, colchicine was associated with significant gastrointestinal (GI) side effects. This study examined whether low-dose colchicine effectively prevents POAF and whether low-dose therapy is associated with lower rates of colchicine-induced GI side effects.
