Reducing the risk of urethral strictures after transurethral surgery for patients with bladder cancer requires effective strategies. We compared the clinical outcomes of a novel drug-injectable urethral catheter set (NIUS) with hyaluronic acid (HA) with those of the conventional intraurethral HA injection method. This six-center, prospective, randomized, single-blind trial included 192 male patients aged ≥ 20 years scheduled to undergo transurethral surgery.

Purpose: Developmentally regulated GTP-binding protein 2 (DRG2) regulates microtubule dynamics and G2/M arrest during docetaxel treatment. Poly ADP-ribose polymerase (PARP) acts as an important repair system for DNA damage caused by docetaxel treatment. This study investigated whether DRG2 expression affects response to PARP inhibitors (olaparib) using prostate cancer cell lines PC3, DU145, LNCaP-FGC, and LNCaP-LN3.

Article Synopsis
  • The study examined sleep patterns in children with nocturnal enuresis (NE) using a brain-wave-sensing device.
  • Ten patients participated, providing data on their sleep and NE occurrences over a week while wearing the MUSE-S™ device.
  • Results indicated that sleep stages affect arousal thresholds; NE events were less responsive to alarms during deep sleep but more responsive during light sleep, suggesting that timing and sleep stage management could improve treatment.

A simple, sensitive and reliable sensing system based on nitrogen-rich porous carbon (NRPC) and transition metals, NRPC/Ni, NRPC/Mn and NRPC/NiMn was developed and successfully applied as electrode materials for the quantitative determination of carbendazim (CBZ). The synergistic effect of NRPC and bimetals with acceptable pore structure together with flower-like morphology resulted in producing a highly conductive and interconnected network in NRPC/NiMn@GCE, which significantly enhanced the detection performance of CBZ. The electrochemical behavior investigated by cyclic voltammetry (CV) showed improved CBZ detection for NRPC/NiMn, due to the controlled adsorption/diffusion process of CBZ by the NRPC/NiMn@GCE electrode.

Background: With the introduction of the da Vinci single-port (SP) robot platform, surgery in a narrow space has become easier, and using this, extraperitoneal radical prostatectomy has been frequently performed recently. However, studies comparing it with existing methods are still lacking. Therefore, in this study, we compared the initial extraperitoneal single-port robot-assisted radical prostatectomy (spRARP) with intraperitoneal multiport robot-assisted radical prostatectomy (mpRARP) and tried to investigate the feasibility of extraperitoneal spRARP.

  • The study focused on improving shockwave lithotripsy, a treatment for kidney stones, by considering how breathing affects targeting and safety.
  • They used a device to mimic kidney movement during breathing and tested artificial stones in a gel, measuring changes after shockwave exposure, along with clinical trials on patients wearing respiratory masks.
  • Results showed better treatment efficiency with regular breathing patterns, a 65.6% success rate in regular breathers compared to 40% in irregular breathers, suggesting that managing breathing can enhance the lithotripsy process and reduce patient discomfort.

Purpose: The regions where patients diagnosed with prostate cancer by biopsy receive prostatectomy are divided into national hub and regional hubs, and to confirm the change in the role of regional hubs compared to national hub.

Materials And Methods: Data from July 2013 to June 2017 encompassing 218,155 patients aged ≥18 years diagnosed with prostate cancer were analyzed using the Health Insurance Review & Assessment Service database. The degree of patient outflow was assessed by dividing the regional diagnosis-to-surgery ratio with the national ratio for each year.

  • - Sirolimus has been identified as a safe and effective treatment for complicated lymphatic malformations (LMs), with a focus on assessing its effectiveness and safety for patients undergoing this therapy.
  • - A study involving 58 patients, mostly young children, showed that 79.3% experienced a reduction in LM volume or clinical symptoms after at least 6 months of sirolimus treatment, with no significant toxicities observed.
  • - The findings suggest that sirolimus could be considered a first-line treatment for complicated LMs, particularly benefiting younger patients and those who haven't responded to other therapies.

Biofilms developed by microorganisms cause an extremely severe clinical problem that leads to drug failure. Bioactive polymeric hydrogels display potential for controlling the formation of microorganism-based biofilms, but their rapid biodegradability in these biofilm sites is still a major challenge. To overcome this, chitosan (CS), a natural functional biomaterial, has been used because of its effective penetrability in the cell wall of microorganisms; however, its fast biodegradability has restricted its further use.

The characteristics of water vapor adsorption depend on the structure, porosity, and functional groups of the material. Metal-organic framework (MOF)-derived carbon (MDC) is a novel material that exhibits a high specific area and tunable pore sizes by exploiting the stable structure and porosity of pure MOF materials. Herein, two types of aluminum-based MOFs were used as precursors to synthesize hydrophobic microporous C-MDC and micro-mesoporous A-MDC via carbonization and activation depending on the type of ligands in the precursors.
