Background: Cisplatin-based chemotherapy has traditionally been the standard treatment for unresectable or metastatic urothelial carcinoma (mUC). Recently, the longstanding paradigm has changed with the emergence of immune checkpoint inhibitors and antibody-drug conjugates, such as pembrolizumab and enfortumab vedotin (EV). This longitudinal descriptive study aimed to identify real-world treatment patterns and assess the outcomes of patients with mUC between 2010 and 2023.

Objectives: Laparoscopic adrenalectomy has been the gold standard surgical procedure. However, the adaptation criteria for malignant tumors and predictors of perioperative outcomes are not well defined. Therefore, this study tried to identify valid predictors for perioperative outcomes of laparoscopic adrenalectomy and consider the adaptation criteria.

In the present study, L-serine (Ser)-modified poly-L-lysine (PLL) was synthesized to develop a biodegradable, kidney-targeted drug carrier for efficient radionuclide therapy in renal cell carcinoma (RCC). Ser-PLL was labeled with In/Y via diethylenetriaminepentaacetic acid (DTPA) chelation for biodistribution analysis/radionuclide therapy. In mice, approximately 91% of the total dose accumulated in the kidney 3 h after intravenous injection of In-labeled Ser-PLL.

Introduction: Metastatic renal cell carcinoma is treated with various regimens. As their outcomes are improving and follow-up periods are growing longer, the rate of unusual visceral metastases may increase.

Case Presentation: A 68-year-old man diagnosed with lung, pancreatic, and renal metastases 9 years after left partial nephrectomy and a diagnosis of pT1a clear cell renal cell carcinoma started molecular targeted therapy using sunitinib.

The purpose of this study is to clarify cardiac autonomic nervous system activity during slow breathing exercises in a supine position. Eighteen healthy young males were participated. Heart rate variability was measured for 5 minutes at rest, 5 minutes at slow breathing, and then 5 minutes at rest.

Background: The modified Glasgow prognostic score (mGPS), which incorporates serum albumin and C-reactive protein levels, reflects systemic inflammation and nutritional status. In this study, we evaluate the role of mGPS as a predictor of prognosis in metastatic renal cell carcinoma treated with nivolumab.

Patients And Methods: Forty-five consecutive patients with metastatic renal cell carcinoma receiving nivolumab therapy after tyrosine kinase inhibitor therapy between September 2013 and August 2019 at our institution were retrospectively analyzed.

Background/aim: Tyrosine kinase inhibitors (TKI) and immune-checkpoint inhibitors (ICI) are treatment options for metastatic renal cell cancer (mRCC). However, the treatment options after nivolumab are unclear.

Patients And Methods: The medical records of 57 consecutive Japanese mRCC patients who underwent treatment with axitinib were reviewed.

Introduction: In spite of the high incidence of infectious complications (ICs), appropriate duration of antimicrobial prophylaxis (AMP) for radical cystectomy (RC) with intestinal urinary diversion (IUD) has not been established. We compared the incidence of ICs after RC with IUD in patients using only intraoperative AMP or extended duration AMP. Risk factors for ICs were also investigated.

Background/aim: Cabazitaxel (CBZ) is approved for docetaxel-resistant castration-resistant prostate cancer (CRPC). This retrospective study aimed at assessing the efficacy and prognostic markers of cabazitaxel treatment in Japanese CRPC patients.

Patients And Methods: The medical records of 44 consecutive Japanese patients with CRPC who started cabazitaxel at our Institution between January 2011 and February 2019 were reviewed and statistically analysed.

Background/aim: Pembrolizumab was approved as second-line treatment for patients with metastatic urothelial cancer (UC) in Japan. We performed a retrospective pilot study to assess the potency of pembrolizumab treatment in Japan.

Patients And Methods: The medical records of 40 consecutive Japanese patients with metastatic UC who started pembrolizumab between January and October 2018 were reviewed and statistically analyzed to clarify the efficacy and safety of the drug.

Human airway trypsin-like protease (HAT) localizes at human bronchial epithelial cells (HBECs). HAT enhanced release of interleukin-8 (IL-8) from HBECs at 10-100 mU/mL and the enhanced release was almost completely abolished by 50 μM leupeptin, a serine protease inhibitor. Previous reports suggested that HAT displays its physiological functions via protease-activated receptor 2 (PAR2).

Rationale: Collecting duct carcinoma (CDC) is a rare type of nonclear renal cell carcinoma, often presenting at an advanced stage of the disease, and standard treatment guidelines have not been established.

Patient Concerns: A 73-year-old man was admitted to our hospital with complaints of fever and lower right back pain.

Diagnoses: Computed tomography revealed a poorly defined tumor of the right kidney without metastasis.

Polymeric micelles, which form through the self-assembly of poly(ethylene glycol)-poly(amino acid) block copolymers, are systemic nanocarriers in targeted cancer therapy. These micelles can encapsulate therapeutic compounds, such as lipophilic substances, charged compounds, and metal complexes, that have characteristics of increased solubility, sustained release, and improved tissue distribution. However, few studies have been conducted on the local distribution of polymeric micelles.

We first discovered human airway trypsin-like protease (HAT) in human mucoid sputum. Precursor HAT (47 kDa), a cell surface type Ⅱ transmembrane serine protease, is proteolyzed to mature HAT (27 kDa). Hitherto, HAT has not been detected in other biological fluids except for human sputum.

This study investigated factors affecting disaster preparedness and evacuation intentions among home-care patients dependent on electrical power for life support. Health professionals interviewed 53 home-care patients using the Kanazawa and Kochi Disaster Preparedness Checklist. About half of the participants requiring continuous artificial ventilation or aspiration indicated that they would not or could not evacuate following a disaster-even though their lives could be at risk.

Ubiquitination is a key post-translational modification in the regulation of numerous biological processes in eukaryotes. The primary roles of ubiquitination are thought to be the triggering of protein degradation and the regulation of signal transduction. During protein ubiquitination, substrate specificity is mainly determined by E3 ubiquitin ligase (E3).

There is increasing evidence that not only the elevation of systolic and diastolic blood pressure (BP) but also the increase in BP variability (or fluctuation) are associated with hypertensive organ damages and the morbidity and mortality of cerebrovascular and cardiovascular events. However, the molecular mechanism whereby the increase in BP variability aggravates hypertensive organ damages remains unknown. Thus, we created a rat chronic model of a combination of hypertension and large BP variability by performing bilateral sino-aortic denervation in spontaneously hypertensive rat.

Background: It has been shown that increased short-term blood pressure (BP) variability (BPV) aggravates hypertensive cardiac remodeling in spontaneously hypertensive rats (SHRs) through a cardiac angiotensin II (angII) system. However, little was known about the renal damage induced by large BPV. Thus, histological changes in the kidney were investigated and candesartan, an angII type 1 receptor blocker (ARB), was also examined to see whether it would prevent renal damage in SHRs with large BPV.

The molecular mechanisms of endothelial dysfunction and vascular calcification have been considered independently and potential links are currently unknown in chronic kidney disease (CKD). Bone morphogenetic protein (BMP) receptor signaling mediates calcification of atherosclerotic plaques. Here we tested whether BMP receptor signaling contributes to endothelial dysfunction, as well as to osteogenic differentiation of vascular smooth muscle cells (VSMCs), in a model of short-term CKD.

Background:  Hypertensive patients with large blood pressure variability (BPV) have aggravated target organ damage. Because the aldosterone/mineralocorticoid receptor (MR) system is a possible mechanism of hypertensive organ damage, we investigated in spontaneously hypertensive rats (SHRs) whether a specific MR blocker, eplerenone, would prevent BPV-induced aggravation of hypertensive cardiac remodeling.

Methods And Results:  A rat model of a combination of hypertension and large BPV was created by performing bilateral sinoaortic denervation (SAD) in SHRs.
