The impact of serum testosterone level to reflect age-related multi-organ functions.

The aim of this study is to examine the correlation between aging, serum total testosterone and biomarkers of multiple organ functions in men. The participants consisted of 12,547 outpatients, whose serum testosterone level was measured. A multiple regression analysis was conducted to determine whether biomarkers including hemoglobin (Hb), hematocrit (Hct), luteinizing hormone (LH), follicle stimulating hormone (FSH), alkaline phosphatase (ALP), albumin (ALB), creatinine (Cre), aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose (Glu), C-reactive protein (CRP), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) values were associated with serum total testosterone concentration. Significant correlations (p < 0.05) were found between total testosterone and Hb, Hct, LH, FSH, ALP, ALB, TG, HDL-C, AST, ALT, Glu, and CRP. In addition, significant correlations (p < 0.05) were found between Hb, Hct, LH, FSH, ALP, ALB, TG and HDL-C associated with [age × testosterone]. This large-scale study provided new insights into correlations between serum testosterone and biomarkers associated with age-related diseases, suggesting that testosterone is especially important for maintaining homeostasis in aging males. Thus, hypogonadism in elderly patients may be associated with multiple organ dysfunctions.

High prevalence of frailty in patients with lower urinary tract symptoms.

AIM: Older adults are more likely to be frail and have a high prevalence of urological diseases such as lower urinary tract symptoms (LUTS). The purpose of this study was to clarify the prevalence and characteristics of comorbid frailty in older patients with urological diseases. METHODS: We retrospectively reviewed the medical records of 970 patient who visited the Department of Urology, Juntendo University Hospital between October 2015 and October 2016. Patients were selected who were 65 years of age or older and were being evaluated by the Kihon Checklist (KCL) to assess frailty. We examined the prevalence of comorbid frailty in urological diseases, identified factors associated with comorbid frailty in urological diseases, and examined KCL scores in urological diseases with a high prevalence of frailty. RESULTS: A total of 405 participants were included. Of these, 21.7% were frail, 20.5% were pre-frail, and 57.8% were robust. LUTS, overactive bladder, and neurogenic bladder showed a statistically significant relationship with comorbid frailty, with high frailty prevalence rates of 44/140 (31.4%), 19/36 (52.8%), and 4/6 (66.7%), respectively. Factors related to the comorbid frailty according to multivariate analysis were female sex (P = 0.001), older age (P < 0.001), and LUTS (P < 0.033). Of the KCL subscale scores, instrumental activities of daily living (P = 0.008), physical function (P < 0.001), oral function (P = 0.008), housebound (P = 0.009), and depression (P = 0.034) were higher in LUTS patients than in non-LUTS patients. CONCLUSIONS: Among patients with urological diseases, those with LUTS were found to have a high prevalence of frailty. Geriatr Gerontol Int 2023; 23: 609-615.

Robot-Assisted Radical Cystectomy with Modified Vesica Ileale Padovana (VIP) Neobladder Configuration Using a Hybrid Approach: Initial Experience.

PURPOSE: We developed a new technique to fold a neobladder (NB) simply by using a modified Vesica Ileale Padovana (VIP) with a hybrid approach. We provide a step-by-step description of our technique as it was used in this initial experience. METHODS: A total of 10 male patients with a median age of 66 years underwent robot-assisted radical cystectomy (RARC) with an orthotopic NB via a hybrid approach from March 2022 to February 2023. After the isolation of the bladder and bilateral pelvic lymphadenectomy, Wallace plate creation was performed, and the robot was undocked. We extracorporeally performed the removal of the specimen and a side-to-side ileoileal anastomosis, and then the VIP NB posterior plate was rotated 90 degrees counterclockwise using a 45 cm detubularized ileum. The robot was redocked; then, circumferential urethra-ileal anastomosis, side-to-middle anterior wall closure, and ureteric afferent limb anastomosis were performed. RESULTS: The median estimated blood loss was 524 mL, and the mean operative time was 496 min. Patients had a high continence rate, and no high-grade complications were observed. CONCLUSION: The NB configuration using the modified VIP method for a hybrid approach is a feasible surgical technique to minimize the movement of robotic forceps. In particular, it may be more useful in Asian individuals with narrow pelvises.

Summary of the clinical practice manual for late-onset hypogonadism.

Testosterone plays an important role in maintaining both physical and mental function. Age-related testosterone depletion contributes to the development of angina, arteriosclerosis, obesity, metabolic syndrome, dementia, frailty, and a range of other conditions. A condition involving age-related testosterone depletion and the associated clinical symptoms is defined as late-onset hypogonadism (LOH). LOH is treated by testosterone replacement therapy. Indications for testosterone replacement therapy are determined by evaluating symptoms and signs.

Kidney Transplantation for a Patient With Protein C Deficiency Using Activated Protein C Concentrate: A Case Report.

BACKGROUND: Thrombophilia causes thrombosis after kidney transplantation (KT). Protein C deficiency is a rare form of hereditary thrombophilia. To our knowledge, there are few reports on KT for patients with protein C deficiency, and there are no reports of KT in patients with protein C deficiency administered with activated protein C concentrate. METHOD: Here we reported the case of a patient with protein C deficiency who underwent KT without the occurrence of any fresh thrombosis after administration of an activated protein C concentrate. The patients was a 49-year-old woman diagnosed with immunoglobulin A nephropathy at 20 years of age. During pregnancy, she experienced deep vein thrombosis of the lower extremities and pulmonary embolism for which she was started on warfarin. After a thorough examination, the patient was diagnosed with protein C deficiency. The patient had end-stage kidney disease and received a preemptive living donor kidney transplant from her mother. RESULTS: To prevent thrombosis, we switched from oral warfarin to continuous heparin 7 days before surgery. Heparin was discontinued 6 hours before surgery, and continuous activated protein C concentrate was administered 12 hours before surgery. Heparin administration was resumed 6 hours after the surgery. Warfarin administration was restarted 3 days after the surgery, and heparin was discontinued 11 days post-surgery. The surgery was performed without complications. After the KT, the patient's renal function steadily improved, and no fresh thrombosis were observed. CONCLUSIONS: Thrombosis can cause graft loss and pulmonary embolism, thus appropriate administration of activated protein C concentrate may help prevent thrombosis.
