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.

Introduction: Shift work disrupts circadian rhythms, causing sleep and mood problems. Sleep reactivity-the sensitivity of sleep to stress-may affect how shift workers cope with these disruptions. This study investigated the relationship between sleep reactivity and shift work, exploring associations between sleep reactivity and sleep disturbance, mood symptoms, and quality of life in shift workers.

Article Synopsis
  • Antireflux surgery (ARS) can alleviate gastroesophageal reflux symptoms even without clear evidence of acid reflux, but predicting symptom improvement has largely relied on acid metrics.
  • A study reviewed data from 121 GERD patients who underwent laparoscopic Nissen fundoplication, analyzing their preoperative and postoperative symptoms alongside reflux measurements like bolus exposure and acid exposure time.
  • Results indicated bolus exposure was the most effective predictor for symptom resolution, showing high diagnostic accuracy for epigastric pain and regurgitation, even in patients without pathological reflux.

Bladder cancer (BCa) with variant histology (VH) is associated with an increased risk of recurrence and progression, as well as worse survival. However, the available literature does not provide the prognostic value of VH based on its tumor burden in non-muscle invasive BCa (NMIBC). The purpose of the present study was to investigate the prognosis of VH in NMIBC with low-tumor volume compared with conventional urothelial carcinoma (UC) with a similar tumor burden.

Background & Objective: Epilepsy has long been associated with stigma and misconceptions. In response, the Korean Epilepsy Society initiated the Epilepsy Renaming project in 2008 to replace the stigmatizing term with a neutral and scientifically grounded name, "cerebroelectric disorder". This study explores the impact of changing terminology on the public discourse surrounding epilepsy.

A main ingredient of Kimchi is Kimchi cabbage, which is soaked in brine to reduce its crispness. Volatile profile of raw Kimchi cabbage (RC) is changed during salting; however, characteristic aroma-active compounds of salted Kimchi cabbage (SC) have not been investigated. The objective of this study was to evaluate changes in aroma characteristics of Kimchi cabbage during salting and fermentation.

Purpose: Prostate-specific membrane antigen (PSMA)-based images, which visually quantify PSMA expression, are used to determine prostate cancer micrometastases. This study evaluated whether a circulating tumor cell (CTC)-based transcript platform, including PSMA mRNA, could help identify potential prognostic markers in prostate cancer.

Experimental Design: We prospectively enrolled 21 healthy individuals and 247 patients with prostate cancer [localized prostate cancer (LPCa), n = 94; metastatic hormone-sensitive prostate cancer (mHSPC), n = 44; and metastatic castration-resistant prostate cancer (mCRPC), n = 109].

Purpose: To identify weight loss prediction models by validating previous models using weight loss success criteria.

Materials And Methods: Patients with morbid obesity from 4 hospitals were retrospectively analyzed between Jan 2019 and 2022. Preoperative demographics, postoperative data, and 1-year follow-up weight loss outcomes were compared between 2 groups who underwent laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB).

Since the outbreak of coronavirus 2019 (COVID-19), detection technologies have been attracting a great deal of attention in molecular diagnosis applications. In particular, the droplet digital PCR (ddPCR) has become a promising tool as it offers absolute quantification of target nucleic acids with high specificity and sensitivity. In recent years, the combination of the isothermal amplification strategies has made ddPCR a popular method for on-site testing by enabling amplification at a constant temperature.

Rational design of electrocatalysts, including an increased catalytic surface area, a unique surface structure, and improved conductivity, for facilitating the hydrogen evolution reaction (HER) is emerging as an important issue. In this work, we consider the engineering of catalyst surfaces as an effective and feasible way to accelerate the HER kinetics. By etching the surface Fe of FeRu alloy nanoparticles (NPs) using hydrofluoric acid (HF), a distorted catalytic surface of FeRu NPs was formed.

For rapid detection of the COVID-19 infection, the digital polymerase chain reaction (dPCR) with higher sensitivity and specificity has been presented as a promising method of point-of-care testing (POCT). Unlike the conventional real-time PCR (qPCR), the dPCR system allows absolute quantification of the target DNA without a calibration curve. Although a number of dPCR systems have previously been reported, most of these previous assays lack multiplexing capabilities.

Background: Tankyrase inhibition stabilises AXINs and antagonises the Wnt/β-catenin pathway in adenomatous polyposis coli (APC)-mutated colorectal cancer (CRC), suggesting that tankyrase is a potential therapeutic target for APC-mutated CRC. However, clinical trials on reported tankyrase inhibitors have been severely limited by on-target toxicity in the gastrointestinal (GI) tract. Herein, we report a new tankyrase-selective inhibitor, STP1002, having preclinical antitumour efficacy without on-target toxicity in APC-mutated CRC models.

Article Synopsis
  • The study looked at a bunch of patients (2,932) who had surgery for stomach cancer in South Korea and checked how following certain guidelines helped with their recovery.* -
  • It found that patients who were compliant with the treatment for specific lymph node areas had a better chance of surviving longer without their cancer coming back compared to those who weren't.* -
  • The researchers want more studies to confirm their findings, but they believe sticking to these guidelines could really help people with stomach cancer live healthier lives.*
