Longitudinal changes in factors affecting postoperative patient satisfaction after robot-assisted radical prostatectomy: an assessment using a patient-reported questionnaire.

Background: Long-term survival can be achieved in patients with localized prostate cancer (PCa). Therefore, maintenance of postoperative quality of life (QOL) and treatment satisfaction are important. Although longitudinal changes in disease-specific QOL are reported, there are few studies investigating which factors longitudinally affect treatment satisfaction in patients who undergo robot-assisted radical prostatectomy (RARP).

Vogt-Koyanagi-Harada disease-like uveitis induced by nivolumab in metastatic renal cell carcinoma.

Introduction: Nivolumab can cause various immune-related adverse events; it rarely induces Vogt-Koyanagi-Harada-disease-like uveitis. Vogt-Koyanagi-Harada-disease is reported to be closely associated with human leukocyte antigen-DR4.

Case Presentation: A 68-year-old man with metastatic renal cancer underwent nephrectomy.

Extrajunctional CLDN10 cooperates with LAT1 and accelerates clear cell renal cell carcinoma progression.

Background & Aims: In addition to their adhesive properties, cell adhesion molecules such as claudins (CLDNs) exhibit signaling ability to organize diverse cellular events. Although the CLDN-adhesion signaling stimulates or inhibits cancer progression, the underlying mechanism remains poorly established. Here, we verified whether and how CLDN10 promotes intracellular signals and malignant phenotypes in clear cell renal cell carcinoma (ccRCC).

A Novel Gene Expression Scoring System Predicts Recurrence in Non-Muscle-Invasive Bladder Cancer Patients.

Background: Despite the high recurrence rate of non-muscle-invasive bladder cancer (NMIBC), there are limitations in accurately predicting recurrence after transurethral resection of bladder tumor (TURBT) based on clinicopathological factors alone. However, prediction of recurrence using biomolecular characteristics of bladder tumors has not been applied to clinical practice. The objective of this study was to establish a new gene expression scoring system for identifying patients at high risk of recurrence.

Tuning the Stability and Kinetics of Dioxazaborocanes.

We investigated the equilibrium reaction of boronic acid (BA), diethanolamines (DEA), and 1,3,6,2-dioxazaborocanes (DOAB) in aqueous solutions, both theoretically and experimentally. Our findings show that the association constant can be adjusted by substituting BA and DEA derivatives, ranging from 10 to 10 M, exhibiting a bell-shaped pH dependency. The highest stability was achieved when the pK values of DEA and BA were closely matched.

Prognosis of lower urinary tract symptoms and function after robot-assisted radical prostatectomy in patients with preoperative low bladder contractility: A prospective, observational study.

Objectives: To examine the prognosis of lower urinary tract symptoms and function after robot-assisted radical prostatectomy (RARP) in patients with low preoperative bladder contractility.

Methods: A total of 115 patients who underwent RARP were enrolled and divided into two groups by preoperative urodynamic findings: normal (patients with bladder contractility index [BCI] ≥ 100; n = 70) and low contractility (patients with BCI < 100; n = 45) groups. Lower urinary tract symptoms and function parameters were prospectively evaluated at 1, 3, 6, 9, and 12 months after RARP in both groups.

Hybrid modeling of T-shaped partial least squares regression and transfer learning for formulation and manufacturing process development of new drug products.

T-shaped partial least squares regression (T-PLSR) is a valuable machine learning technique for the formulation and manufacturing process development of new drug products. An accurate T-PLSR model requires experimental data with multiple formulations and process conditions. However, it is usually challenging to collect comprehensive experimental data using large-scale manufacturing equipment because of the cost, time, and large consumption of raw materials.

Sex Differences in 5-Year Outcomes After Deferral of Revascularization Following Physiological Coronary Assessment.

The relationship between sex differences and long-term outcomes after fractional flow reserve (FFR)- and instantaneous wave-free ratio (iFR)-guided deferral of revascularization has yet to be elucidated. From the J-CONFIRM registry (long-term outcomes of Japanese patients with deferral of coronary intervention based on FFR in a multicenter registry), this study included 432 lesions from 385 patients (men, 323 lesions in 286 patients; women, 109 lesions in 99 patients) with paired data of FFR and iFR. The primary endpoint was the cumulative 5-year incidence of target vessel failure (TVF), including cardiac death, target vessel-related myocardial infarction, and clinically driven target vessel revascularization.

A case report on intravascular lithotripsy to facilitate retrograde wire passage from the subintimal to the luminal space in a calcified chronic total occlusion.

Background: Severe calcifications are a major reason for failures in chronic total coronary occlusions, as they can obstruct the wire passage both in the antegrade and retrograde technique.

Case Summary: The proximal occlusion of the left anterior descending artery in a 75-year-old man presented with a completely concentric calcified ring all along the segment proximal to the occlusion. The antegrade wire could not pass the calcified occlusion, and in a retrograde approach the right posterior descending artery the retrograde wire was not able to enter the lumen from a subintimal position outside of the calcified ring.

Prognostic Impact of Renal Function on 5-Year Outcomes After Fractional Flow Reserve-Guided Deferral of Revascularization.

Background Chronic kidney disease (CKD) might influence fractional flow reserve (FFR) value, potentially attenuating its prognostic utility. However, few large-scale data are available regarding clinical outcomes after FFR-guided deferral of revascularization in patients with CKD. Methods and Results From the J-CONFIRM registry (Long-Term Outcomes of Japanese Patients With Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter Registry), 1218 patients were divided into 3 groups according to renal function: (1) non-CKD (estimated glomerular filtration rate ≥60 mL/min per 1.

Diversity and composition of flower-visiting insects and related factors in three fruit tree species.

Animal-mediated pollination is an essential ecosystem service for the production of many fruit trees. To reveal the community composition of flower-visiting wild insects which potentially contribute to fruit production and to examine the effects of geographic location, local meteorological conditions and locally introduced domesticated pollinators on them, we investigated the community composition of insects visiting the flowers (hereafter, "visitors") of apple, Japanese pear and Oriental persimmon for 1‒3 years at 20 sites around Japan. While most of the variation (82%) of the community composition was explained by tree species with a slight contribution by geographic distance (2%), maximum temperature and tree species contributed 62% and 41% of the variation in total abundance of the visitors, respectively.

Mechanism of Androgen-Independent Stromal Proliferation in Benign Prostatic Hyperplasia.

Benign prostatic hyperplasia (BPH) is a chronic proliferative disease showing stromal-dominant proliferation. However, the detailed proliferation mechanism has remained unclear. Although aging and androgen have been reported as definitive risk factors for BPH, recent studies have focused on the involvement of androgen-independent factors.

The current status of prostate cancer treatment and PSMA theranostics.

In the treatment of cancer, understanding the disease status, or accurate staging, is extremely important, and various imaging techniques are used. Computed tomography (CT), magnetic resonance imaging, and scintigrams are commonly used for solid tumors, and advances in these technologies have improved the accuracy of diagnosis. In the clinical practice of prostate cancer, CT and bone scans have been considered especially important for detecting metastases.

Five-Year Outcomes After Fractional Flow Reserve-Guided Deferral of Revascularization in Infarct-Related Artery Lesions.

Background: Little evidence is available about the long-term safety of fractional flow reserve (FFR)-guided deferral of revascularization in infarct-related artery (IRA) lesions, especially when measuring FFR in the late setting after myocardial infarction (MI). This study aimed to assess the long-term outcomes after deferral of revascularization in IRA lesions based on FFR assessed in the late phase of post-MI.

Methods: From the J-CONFIRM registry (Long-Term Outcomes of Japanese Patients With Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter Registry), data on 1447 lesions (1263 patients) were divided into 2 groups: the IRA and non-IRA groups.

Objective Evaluation With Noncontrast Computed Tomography Can Reveal Calcified Plaque Solidity in Peripheral Artery Diseases.

Purpose: The presence of severely calcified plaque remains problematic in endovascular therapy, and no specific endovascular treatment strategy has been established. Estimating plaque solidity before the procedure may help operators penetrate calcified plaque with a guide wire. The aim of this study was to establish a method of measuring plaque solidity with noncontrast computed tomography (CT).

Associations between fetal or infancy pet exposure and food allergies: The Japan Environment and Children's Study.

The hygiene hypothesis suggests that pet exposure is effective in preventing allergic disease, and some studies have reported the beneficial effects of dog exposure during fetal development or early infancy on food allergy. However, the effects of exposure to pets other than dogs on the kinds of food allergies remains unaddressed. This study aimed to explore the effect of exposure to various species of pets on the risk of food allergies.

Involvement of Mast-Cell-Tryptase- and Protease-Activated Receptor 2-Mediated Signaling and Urothelial Barrier Dysfunction with Reduced Uroplakin II Expression in Bladder Hyperactivity Induced by Chronic Bladder Ischemia in the Rat.

We aimed to investigate the relationship between mast cell (MC) infiltration into the bladder with urothelial barrier dysfunction and bladder hyperactivity in a chronic bladder ischemia (CBI) rat model. We compared CBI rats (CBI group; n = 10) with normal rats (control group; n = 10). We measured the expression of mast cell tryptase (MCT) and protease-activated receptor 2 (PAR2), which are correlated with C fiber activation via MCT, and Uroplakins (UP Ia, Ib, II and III), which are critical to urothelial barrier function, via Western blotting.

Impact of bystander cardiopulmonary resuscitation on neurological outcomes in patients undergoing veno-arterial extracorporeal membrane oxygenation.

Background: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) requires a large amount of economic and human resources. The presence of bystander cardiopulmonary resuscitation (CPR) was focused on selecting appropriate V-A ECMO candidates.

Result: This study retrospectively enrolled 39 patients with V-A ECMO due to out-of-hospital cardiac arrest (CA) between January 2010 and March 2019.

Low Risk of Venous Thromboembolism After Robot-assisted Radical Prostatectomy Through Systemic Image Assessment: A Prospective Study.

Background/aim: The aim of the study was to evaluate the risk of venous thromboembolism (VTE) after robot-assisted radical prostatectomy (RARP) and discuss whether a uniform prophylaxis for VTE after radical prostatectomy is also suitable for robotic surgery. On this context, we investigated the incidence and risk factors of VTE, including asymptomatic events, after RARP compared to transurethral resection of bladder tumor (TUR-BT).

Patients And Methods: The participants were 209 patients with localized prostate cancer who underwent RARP, and 93 patients who underwent TUR-BT as controls.
