Testosterone replacement elevates the serum uric acid levels in patients with female to male gender identity disorder

Gender identity disorder (GID) results from a disagreement between a person's biological sex and the gender to which he or she identifies. With respect to the treatment of female to male GID, testosterone replacement therapy (TRT) is available. The uric acid (UA) level can be influenced by testosterone; however, the early effects and dose-dependency of TRT on the serum UA concentration have not been evaluated in this population. We herein conducted a dose-response analysis of TRT in 160 patients with female to male GID. The TRT consisted of three treatment groups who received intramuscular injections of testosterone enanthate: 125 mg every two weeks, 250 mg every three weeks and 250 mg every two weeks. Consequently, serum UA elevation was observed after three months of TRT and there was a tendency toward testosterone dose-dependency. The onset of hyperuricemia was more prevalent in the group who received the higher dose. We also demonstrated a positive correlation between increased levels of serum UA and serum creatinine. Since the level of serum creatinine represents an individual's muscle volume and the muscle is a major source of purine, which induces UA upregulation, the serum UA elevation observed during TRT is at least partially attributed to an increase in muscle mass. This is the first study showing an association between serum UA elevation and a TRT-induced increase in muscle mass. The current study provides important information regarding TRT for the follow-up and management of the serum UA levels in GID patients

Robotic Renal Autotransplantation: First Case Outside of North America

A 38-year-old woman with a 2.7-cm left ureteral stenosis requiring chronic ureteral stent exchange elected to undergo robotic renal autotransplantation. Left ureteropelvic junction obstruction (UPJO) was also suspected. Robotic donor nephrectomy contributed to the fine dissection for desmoplastic changes. The kidney was removed through a Gelport and examined on ice. UPJO was not seen. An end-to-side robotic anastomosis was created between the renal and external iliac vessels. The console time was 507 min, and the warm ischemia time was 4 min 5 sec. She became stent-free. Robotic renal autotransplantation is a new, minimally invasive approach to renal preservation

High-fat/high-sucrose diet-induced renal changes in obese diabetic mice: a comparison with / and KK-Ay mice

Many genetic and environmental factors are involved in the development and progression of diabetic kidney disease (DKD), and its pathology shows various characteristics. Animal models of DKD play an important role in elucidating its pathogenesis and developing new therapies. In this study, we investigated the pathophysiological features of two DKD animal models: / mice (background of hyperglycemia) and KK-Ay mice (background of hyperinsulinemia). Male and female mice were fed a high-fat/high-sucrose (HFS) diet for eight weeks. Two mouse models fed the HFS diet showed increases in urinary protein, kidney weight, and glomerular size, but these changes were pronounced in KK-Ay mice. Pathological examination revealed tubulointerstitial fibrosis in KK-Ay mice fed the HFS diet, but not in / mice. In addition, fat accumulation was observed in the macula densa of / mice and in the glomeruli of KK-Ay mice fed with the HFS diet. In conclusion, an HFS diet exacerbates renal lesions with tubulointerstitial fibrosis in KK-Ay mice, and KK-Ay mice fed an HFS diet are expected to be useful as a DKD model

Efficacy and Safety of Esaxerenone in Hypertensive Patients with Diabetic Kidney Disease: A Multicenter, Open-Label, Prospective Study

Introduction Clinical data of esaxerenone in hypertensive patients with diabetic kidney disease (DKD) are lacking. We evaluated the efficacy and safety of esaxerenone in patients with DKD and an inadequate response to blood pressure (BP)-lowering treatment. Methods In this multicenter, open-label, prospective study, patients were divided into urinary albumin-to-creatinine ratio subcohorts (UACR  Results In total, 113 patients were enrolled. Morning home SBP/DBP significantly decreased from baseline to EOT in the total population (− 11.6/− 5.2 mmHg, both p  Conclusion Esaxerenone demonstrated a BP-lowering effect and improved albuminuria. The effects were consistent regardless of the severity of albuminuria without clinically relevant serum potassium elevation and eGFR reduction

Host Prostaglandin E2-EP3 Signaling Regulates Tumor-Associated Angiogenesis and Tumor Growth

Nonsteroidal antiinflammatories are known to suppress incidence and progression of malignancies including colorectal cancers. However, the precise mechanism of this action remains unknown. Using prostaglandin (PG) receptor knockout mice, we have evaluated a role of PGs in tumor-associated angiogenesis and tumor growth, and identified PG receptors involved. Sarcoma-180 cells implanted in wild-type (WT) mice formed a tumor with extensive angiogenesis, which was greatly suppressed by specific inhibitors for cyclooxygenase (COX)-2 but not for COX-1. Angiogenesis in sponge implantation model, which can mimic tumor-stromal angiogenesis, was markedly suppressed in mice lacking EP3 (EP3−/−) with reduced expression of vascular endothelial growth factor (VEGF) around the sponge implants. Further, implanted tumor growth (sarcoma-180, Lewis lung carcinoma) was markedly suppressed in EP3−/−, in which tumor-associated angiogenesis was also reduced. Immunohistochemical analysis revealed that major VEGF-expressing cells in the stroma were CD3/Mac-1 double-negative fibroblasts, and that VEGF-expression in the stroma was markedly reduced in EP3−/−, compared with WT. Application of an EP3 receptor antagonist inhibited tumor growth and angiogenesis in WT, but not in EP3−/−. These results demonstrate significance of host stromal PGE2-EP3 receptor signaling in tumor development and angiogenesis. An EP3 receptor antagonist may be a candidate of chemopreventive agents effective for malignant tumors

Burned-out Prostate Cancer ? Primary Metastatic Cancer Not Detected on Repeat Biopsy

Metastatic prostate cancer (PCa) cases that cannot be detected on repeat prostate biopsy are extremely rare. Our patient was a 51-year-old Japanese man diagnosed as metastatic PCa by histopathological examination of lesions obtained bone biopsy and lymph node dissection. The primary tumor was not detected after repeated prostate biopsy. Metastatic PCa was diagnosed based on immunohistochemical staining: PSA, AR, P504S, and NKX3.1 of bone and lymph node with metastasis. We speculate that the primary PCa was “burned-out,” demonstrating remote metastases with no apparent primary tumor in the prostate. Burned-out PCa may be difficult to diagnose and treat due to its rarity

A Method of Calculation Asymmetrical Constants Based on Lock Test for Single-sided Linear Induction Motor and a Consideration of Thrust Control

The constants of each phase of linear induction motor (L1M) are different because of it's structurc. It is important that the method of calculating asymmctrical constants is established,because the asymmetrical constants cause the thrust pulsation. 1n this paper,a new method of calculating asymmetrical constants of LIM is proposed. The results of simulation performed by the calculated constants are compared with the experimental results. Moreover,some simulation results of thrust control are presel1ted.departmental bulletin pape
