RESUMEN

BACKGROUND: Transgender individuals undergo the gender-affirming hormone therapy (GAHT) to achieve physical changes consistent with their gender identity. Few studies are available on the long-term safety and efficacy of GAHT. OBJECTIVES: To investigate the long-term physical effects and the safety of the testosterone therapy for trans men and to assess the impact of differential hormone dose. MATERIALS AND METHODS: Trans men who initiated GAHT between May 2000 and December 2021 were included in this retrospective analysis. Physical findings (body mass index, body fat percentage (BFP), lean body mass (LBM), and grip strength), blood testing results (hemoglobin, hematocrit, uric acid, creatinine, total cholesterol, triglycerides, and total testosterone), and menstrual cessation were recorded. We assessed the effects of testosterone on body composition changes and laboratory parameters, comparing a low-dose group (≤ 62.5 mg/wk) to a high-dose group (> 62.5 mg/wk). RESULTS: Of 291 participants, 188 patients (64.6%) were in the low-dose group and 103 (35.4%) in the high-dose group. Cumulative menstrual cessation rates up to 12 months were not significantly different between groups. Both groups showed a decrease in BFP and an increase in LBM during the first year of therapy, followed by a slight increase in both over the long term. The high-dose group exhibited greater LBM gains during the first year. Higher hormone doses and lower initial LBM values were associated with LBM increases at 3 and 6 months (3 mo, P = 0.006, P < 0.001; 6 mo, P = 0.015, P < 0.001). There were no long-term, dose-dependent side effects such as polycythemia or dyslipidemia. CONCLUSION: Long-term GAHT for trans men is safe and effective. Low-dose testosterone administration is sufficient to increase LBM in trans men. Higher testosterone doses can lead to an earlier increase in muscle mass.

RESUMEN

INTRODUCTION: Antimicrobial susceptibility patterns of bacterial pathogens isolated from patients with complicated urinary tract infections were analyzed using the national surveillance data, comprising 793 bacterial strains from eight clinically relevant species. MATERIALS AND METHODS: Data were collected for the fourth national surveillance project from July 2020 to December 2021 by the Japanese Society of Chemotherapy, the Japanese Association for Infectious Disease, and the Japanese Society of Clinical Microbiology. Surveillance was supervised with the cooperation of 43 medical institutions throughout Japan. RESULTS: Fluoroquinolone required a minimum inhibitory concentration (MIC) of 2-64 mg/L to inhibit the 330 tested Escherichia coli strains. The proportion of levofloxacin-resistant E. coli strains increased from 28.6% in 2008 to 29.6% in 2011, 38.5% in 2015, and 44.5% in 2021. The proportion of levofloxacin-resistant strains of Pseudomonas aeruginosa also increased from previous survey results, showing a continuing downward trend. Conversely, the proportion of levofloxacin-resistant strains of Enterococcus faecalis decreased relative to previous reports. Neither multidrug-resistant P. aeruginosa nor carbapenem-resistant Enterobacteriaceae were detected. For methicillin-resistant Staphylococcus aureus (MRSA), the proportion of vancomycin-susceptible strains (MIC of 2 µg/mL) decreased from 14.7% to 7.7%. DISCUSSION: Bacterial strains that produced extended-spectrum ß-lactamase included E. coli (82/330 strains, 24.8%), Klebsiella pneumoniae (11/68 strains, 16.2%), and Proteus mirabilis (4/26 strains, 15.4%). As compared to previous surveillance reports, these strains showed an increase in proportion over the years.

RESUMEN

Boron neutron capture therapy (BNCT) is a treatment method that focuses on improving the cure rate of patients with cancer who are difficult to treat using traditional clinical methods. By utilizing the high neutron absorption cross-section of boron, material rich in boron inside tumor cells can absorb neutrons and release high-energy ions, thereby destroying tumor cells. Owing to the short range of alpha particles, this method can precisely target tumor cells while minimizing the inflicted damage to the surrounding normal tissues, making it a potentially advantageous method for treating tumors. Globally, institutions have progressed in registered clinical trials of BNCT for multiple body parts. This review summarized the current achievements in registered clinical trials, Investigator-initiated clinical trials, aimed to integrate the latest clinical research literature on BNCT and to shed light on future study directions.

RESUMEN

This review presents the latest insights on robot-assisted kidney autotransplantation (RAKAT). RAKAT is a minimally invasive surgical procedure and represents a promising alternative to conventional laparoscopic nephrectomy followed by open kidney transplantation for the treatment of various complex urological and vascular conditions. RAKAT can be performed either extracorporeally or intracorporeally. Additionally, a single-port approach can be performed through one small incision without the need to reposition the patient. Of 86 patients undergoing RAKAT, 8 (9.3%) developed postoperative > Grade 2 Clavien-Dindo (CD) complications. Although the feasibility of RAKAT was established in 2014, the long-term efficacy and safety along with outcomes of this surgical approach are still being evaluated, and additional studies are needed. With improvements in the technology of RAKAT and as surgeons gain more experience, RAKAT should become increasingly used and further refined, thereby leading to improved surgical outcomes and improved patients' quality of life.

RESUMEN

The Japanese surveillance committee conducted a third nationwide surveillance of antimicrobial susceptibility of acute uncomplicated cystitis at 55 facilities throughout Japan between April 2020 and September 2021. In this surveillance, we investigated the susceptibility of Escherichia coli (E. coli), Klebsiella pneumoniae (K. pneumoniae), and Staphylococcus saprophyticus (S. saprophyticus) for various antimicrobial agents by isolating and culturing bacteria from urine samples. In total, 823 strains were isolated from 848 patients and 569 strains of target bacteria, including E. coli (n = 529, 92.9 %), K. pneumoniae (n = 28, 4.9 %), and S. saprophyticus (n = 12, 2.2 %) were isolated. The minimum inhibitory concentrations of 18 antibacterial agents were determined according to the Clinical and Laboratory Standards Institute manual. In premenopausal patients, there were 31 (10.5 %) and 20 (6.8 %) fluoroquinolone (FQ)-resistant E. coli and extended-spectrum ß-lactamase (ESBL)-producing E. coli, respectively. On the other hand, in postmenopausal patients, there were 75 (32.1 %) and 36 (15.4 %) FQ-resistant E. coli and ESBL-producing E. coli, respectively. The rate of FQ-resistant E. coli and ESBL-producing E. coli in post-menopausal women was higher than that for our previous nationwide surveillance (20.7 % and 32.1 %: p = 0.0004, 10.0 % and 15.4 %; p = 0.0259). For pre-menopausal women, there was no significant difference in the rate of FQ-resistant E. coli and ESBL-producing E. coli between this and previous reports, but the frequency of FQ-resistant E. coli and ESBL-producing E. coli exhibited a gradual increase. For appropriate antimicrobial agent selection and usage, it is essential for clinicians to be aware of the high rate of these antimicrobial-resistant bacteria in acute uncomplicated cystitis in Japan.

RESUMEN

PURPOSE: Radiological tumor burden has been reported to be prognostic in many malignancies in the immunotherapy era, yet whether it is prognostic in patients with metastatic urothelial carcinoma (mUC) treated with pembrolizumab remains uninvestigated. We sought to assess the predictive and prognostic value of radiological tumor burden in patients with mUC. METHODS: We performed a retrospective analysis of 308 patients with mUC treated with pembrolizumab. Radiological tumor burden was represented by baseline tumor size (BTS) and baseline tumor number (BTN). Optimal cut-off value of BTS was determined as 50 mm using the Youden index (small BTS: n = 194, large BTS: n = 114). Overall (OS), cancer-specific (CSS), progression-free survival (PFS), and objective response rate (ORR) were compared. Non-linear associations between BTS and OS and CSS were evaluated using restricted cubic splines. RESULTS: Patients with large BTS were less likely to have undergone the surgical resection of the primary tumor (P = 0.01), and more likely to have liver metastasis (P < 0.001) and more metastatic lesions (P < 0.001). On multivariable analyses controlling for the effects of confounders (resection of primary tumor, metastatic site, number of metastases and lactate dehydrogenase level), large BTS and high BTN were independently associated with worse OS (HR 1.52; P = 0.015, and HR 1.69; P = 0.018, respectively) and CSS (HR 1.59; P = 0.01, and HR 1.66; P = 0.031, respectively), but not PFS. Restricted cubic splines revealed BTS was correlated with OS and CSS in linear relationships. Additionally, large BTS was significantly predictive of lower ORR and complete response rate on univariable analyses (P = 0.041 and P = 0.032, respectively), but its association disappeared on multivariable analyses. CONCLUSION: Radiological tumor burden has independent prognostic value with a linear relationship in pembrolizumab-treated patients with mUC and might help drive the earlier introduction of second-line pembrolizumab and/or switching to subsequent therapies.

RESUMEN

One-third of renal cell carcinomas (RCCs) without metastases develop metastatic disease after extirpative surgery for the primary tumors. The majority of metastatic RCC cases, along with treated primary lesions, involve limited lesions termed "oligo-recurrent" disease. The role of metastasis-directed therapy (MDT), including stereotactic body radiation therapy (SBRT) and metastasectomy, in the treatment of oligo-recurrent RCC has evolved. Although the surgical resection of all lesions alone can have a curative intent, SBRT is a valuable treatment option, especially for patients concurrently receiving systemic therapy. Contemporary immune checkpoint inhibitor (ICI) combination therapies remain central to the management of metastatic RCC. However, one objective of MDT is to delay the initiation of systemic therapies, thereby sparing patients from potentially unnecessary burdens. Undertaking MDT for cases showing progression under systemic therapies, known as "oligo-progression", can be complex in considering the treatment approach. Its efficacy may be diminished compared to patients with stable disease. SBRT combined with ICI can be a promising treatment for these cases because radiation therapy has been shown to affect the tumor microenvironment and areas beyond the irradiated sites. This may enhance the efficacy of ICIs, although their efficacy has only been demonstrated in clinical trials.

RESUMEN

Neisseria gonorrhoeae is one of the important pathogens of sexually transmitted infections. N. gonorrhoeae is rapidly becoming antimicrobial resistant, and there are few drugs that are effective in the initial treatment of gonorrhea. To understand the trends of antimicrobial susceptibility of N. gonorrhoeae, the Surveillance Committee of the Japanese Society of Infectious Diseases, the Japanese Society for Chemotherapy, and the Japanese Society of Clinical Microbiology conducted the third nationwide antimicrobial susceptibility surveillance of N. gonorrhoeae isolated from male urethritis. The specimens were collected from male patients with urethritis at 30 facilities from May 2016 to July 2017. From the 159 specimens collected, 87 N. gonorrhoeae strains were isolated, and 85 were tested for susceptibility to 21 antimicrobial agents. All strains were non-susceptible to penicillin G. Seven strains (8.2%) were ß-lactamase-producing strains. The rates of susceptibility to cefixime and cefpodoxime were 96.5% and 52.9%, respectively. Three strains were non-susceptible with a minimum inhibitory concentration (MIC) of 0.5 mg/L for cefixime. None of the strains were resistant to ceftriaxone or spectinomycin. The susceptibility rate for ciprofloxacin was 23.5% (20 strains), and no strains showed intermediate susceptibility. The susceptibility rate against azithromycin was 81.2%, with one strain isolated with a MIC of 8 mg/L against azithromycin. The results of this surveillance indicate that ceftriaxone and spectinomycin, which are currently recommended for gonococcal infections in Japan, appear to be effective. It will be necessary to further expand the scale of the next surveillance to understand the current status of drug-resistant N. gonorrhoeae in Japan.

RESUMEN

Background: The vaginal microbiota can be altered by uropathogenic bacteria associated with recurrent cystitis (RC), and the vaginal administration of Lactobacillus have suggested certain effects to prevent RC. The relationship between vaginal microbiota and the development of RC has not been elucidated. We aimed to clarify the etiology of RC from vaginal microbiota and importance of vaginal Lactobacillus. Methods: Vaginal samples obtained from 39 postmenopausal women were classified into four groups: healthy controls; uncomplicated cystitis; RC; and prevention (prevented RC by Lactobacillus crispatus-containing vaginal suppositories). Principal coordinate analysis and beta-diversity analysis was used to assess 16S rRNA gene sequencing data from the vaginal microbiome. Results: Cluster analysis divided the vaginal bacterial communities among 129 vaginal samples into three clusters (A, B, and C). Fourteen of 14 (100%) samples from the RC group and 51 of 53 (96%) samples from the prevention group were in clusters B and C, while 29 of 38 (76%) samples from the healthy group and 14 of 24 (58%) samples from the uncomplicated cystitis group were in cluster A. The principal coordinate analysis showed that plots in the uncomplicated cystitis group were similar to the healthy group, indicating a large separation between the RC group and the uncomplicated cystitis group. On beta-diversity analysis, there were significant differences between the healthy group and the uncomplicated cystitis group (p = 0.045), and between the RC group and the uncomplicated cystitis group or the healthy group (p = 0.001, p = 0.001, respectively). There were no significant differences between the RC group and the prevention group (p = 0.446). The top six taxa were as follows: Prevotella, Lactobacillus, Streptococcus, Enterobacteriaceae, Anaerococcus, and Bifidobacterium. Among patients with RC, Lactobacillus was undetectable before administration of suppositories, while the median relative abundance of Lactobacillus was 19% during administration of suppositories (p = 0.0211), reducing the average cystitis episodes per year (6.3 vs. 2.4, p = 0.0015). Conclusion: The vaginal microbiota of postmenopausal women with RC is differed from healthy controls and uncomplicated cystitis in terms of lack of Lactobacillus and relatively dominant of Enterobacteriaceae. Vaginal administration of Lactobacillus-containing suppositories can prevent RC by stabilizing vaginal dysbiosis and causing a loss of pathogenic bacteria virulence.

RESUMEN

OBJECTIVES: To elucidate the mechanism of Lactobacillus crispatus (L. crispatus) suppositories to prevent patients from recurrent cystitis (RC), independent from viable-Lactobacilli-bacteria- and acid-dependent ones such as hydrogen peroxide and lactate. METHODS: We used the GAI98322 strain of L. crispatus in all experiments and pH-matched. cell-free culture supernatant of L. crispatus (CFCS) was collected. The growth inhibitory activity and the biofilm formation inhibitory activity of the CFCS against uropathogenic Escherichia coli (UPEC), Extended Spectrum beta (ß) Lactamase producing (ESBL+) UPEC, and Pseudomonas aeruginosa (P. aeruginosa) was assessed by agar-disk diffusion tests and crystal violet assay. Also, CFCS was subjected to mass spectrometry to specify ingredients. RESULTS: The CFCS suppressed the proliferation of E. coli, ESBL + E. coli, and P. aeruginosa. Also, the CFCS at a concentration of 40% significantly impeded the biofilm formation of these three bacteria. The aggregation-promoting factor and Lysin was detected from CFCS. CONCLUSIONS: The cell-free supernatant from the GAI98322 strain of L. crispatus inhibits the growth/biofilm formation of broad pathogens by aggregation promoting factor and lysin, which may prevent hosts from RC regardless of the antimicrobial resistance of the pathogens and even under pH modulation.

RESUMEN

We carried out a molecular biological analysis of extended-spectrum ß-lactamase (ESBL)-producing E. coli strains and their sensitivity to flomoxef (FMOX). Sequence type (ST) analysis by multilocus sequence typing (MLST) and classification of ESBL genotypes by multiplex PCR were performed on ESBL-producing E. coli strains isolated from urine samples collected from patients treated at our institution between 2008 and 2018. These sequences were compared with results for antimicrobial drug susceptibility determined using a micro-liquid dilution method. We also analyzed cases treated with FMOX at our institution to examine its clinical efficacy. Of the 911 E. coli strains identified, 158 (17.3%) were ESBL-producing. Of these, 67.7% (107/158) were strain ST-131 in ST analysis. Nearly all (154/158; 97.5%) were CTX-M genotypes, with M-14 and M-27 predominating. The isolated strains were sensitive to FMOX in drug susceptibility tests. Among the patient samples, 33 cases received FMOX, and of these, 5 had ESBL-producing E. coli. Among these five cases, three received FMOX for surgical prophylaxis as urinary carriers of ESBL-producing E. coli, and postoperative infections were prevented in all three patients. The other two patients received FMOX treatment for urinary tract infections. FMOX treatment was successful for one, and the other was switched to carbapenem. Our results suggest that FMOX has efficacy for perioperative prophylactic administration in urologic surgery involving carriers of ESBL-producing bacteria and for therapeutic administration for urinary tract infections. Use of FMOX avoids over-reliance on carbapenems or ß-lactamase inhibitors and thus is an effective antimicrobial countermeasure.

RESUMEN

Intravesical immunotherapy using bacillus Calmette-Guérin (BCG) is recommended for patients with intermediate- to high-risk non-muscle invasive bladder cancer. Bladder tuberculosis (TB) is a rare complication of BCG therapy. The present study describes the case of a 73-year-old man who underwent intravesical BCG therapy for urothelial carcinoma in situ of the bladder. Red patches around the resection scar were first detected 1 year and 5 months after BCG treatment; these findings gradually spread to encompass more of the bladder wall. Transurethral biopsy revealed a benign lesion, but the patient developed bilateral hydronephrosis and mild voiding dysfunction. The patient was eventually diagnosed with bladder TB by mycobacterial urine culture and TB-specific polymerase chain reaction (PCR). The patient was given multidrug therapy (isoniazid, rifampicin and ethambutol) and their bladder TB was completely cured; however, their voiding dysfunction and bilateral hydronephrosis did not fully improve. Bladder TB can occur long after intravesical BCG administration and cystoscopy findings consistent with inflammation can be the key to suspecting this condition. Acid-fast examination and PCR testing of a urine sample are necessary for early diagnosis.

RESUMEN

Combination therapy with anti-cytotoxic T lymphocyte-associated protein 4 (CTLA-4) and anti-programmed death-1 (PD-1) monoclonal antibodies (mAbs) has dramatically improved the prognosis of patients with multiple types of cancer, including renal cell carcinoma (RCC). However, more than half of RCC patients fail to respond to this therapy. Regulatory T cells (Treg cells) are a subset of highly immunosuppressive CD4+ T cells that promote the immune escape of tumors by suppressing effector T cells in the tumor microenvironment (TME) through various mechanisms. CTLA-4 is constitutively expressed in Treg cells and is regarded as a key molecule for Treg-cell-mediated immunosuppressive functions, suppressing antigen-presenting cells by binding to CD80/CD86. Reducing Treg cells in the TME with an anti-CTLA-4 mAb with antibody-dependent cellular cytotoxicity (ADCC) activity is considered an essential mechanism to achieve tumor regression. In contrast, we demonstrated that CTLA-4 blockade without ADCC activity enhanced CD28 costimulatory signaling pathways in Treg cells and promoted Treg-cell proliferation in mouse models. CTLA-4 blockade also augmented CTLA-4-independent immunosuppressive functions, including cytokine production, leading to insufficient antitumor effects. Similar results were also observed in human peripheral blood lymphocytes and tumor-infiltrating lymphocytes from patients with RCC. Our findings highlight the importance of Treg-cell depletion to achieve tumor regression in response to CTLA-4 blockade therapies.

RESUMEN

An ectopic kidney is a rare congenital defect in which the kidney does not migrate to its normal anatomical position. In the present study, a robot-assisted radical cystectomy and intracorporeal urinary diversion were performed for a patient with an ectopic kidney. The present study describes the case of a 72-year-old male patient who was diagnosed with a bladder tumor by magnetic resonance imaging and cystoscopy. A transurethral resection of the bladder tumor was performed. The pathological examination revealed an invasive urothelial carcinoma. Contrast-enhanced computed tomography revealed an ectopic left kidney in the upper pelvis. A robot-assisted radical cystectomy, extended lymph node dissection and intracorporeal urinary diversion were performed. On the whole, as demonstrated herein, a robot-assisted radical cystectomy with intracorporeal urinary diversion is a feasible approach for muscle-invasive bladder cancer complicated by an ectopic kidney.

RESUMEN

Bladder cancer is an often widely disseminated and deadly cancer. To block the malignant outgrowth of bladder cancer, we must elucidate the molecular-level characteristics of not only bladder cancer cells but also their surrounding milieu. As part of this effort, we have long been studying extracellular S100A8/A9, which is elevated by the inflammation associated with certain cancers. Extracellularly enriched S100A8/A9 can hasten a shift to metastatic transition in multiple types of cancer cells. Intriguingly, high-level S100A8/A9 has been detected in the urine of bladder-cancer patients, and the level increases with the stage of malignancy. Nonetheless, S100A8/A9 has been investigated mainly as a potential biomarker of bladder cancers, and there have been no investigations of its role in bladder-cancer growth and metastasis. We herein report that extracellular S100A8/A9 induces upregulation of growth, migration and invasion in bladder cancer cells through its binding with cell-surface Toll-like receptor 4 (TLR4). Our molecular analysis revealed the TLR4 downstream signal that accelerates such cancer cell events. Tumor progression locus 2 (TPL2) was a key factor facilitating the aggressiveness of cancer cells. Upon binding of S100A8/A9 with TLR4, TPL2 activation was enhanced by an action with a TLR4 adaptor molecule, TIR domain-containing adaptor protein (TIRAP), which in turn led to activation of the mitogen-activated protein kinase (MAPK) cascade of TPL2. Finally, we showed that sustained inhibition of TLR4 in cancer cells effectively dampened cancer survival in vivo. Collectively, our results indicate that the S100A8/A9-TLR4-TPL2 axis influences the growth, survival, and invasive motility of bladder cancer cells.

RESUMEN

OBJECTIVE: To evaluate whether a 2-dimensional(2D) model describes the surgical difficulty of a renal mass accurately comparable to that obtained using a 3D model with the Simplified PADUA REnal nephrometry system (SPARE). METHODS: A total of 100 patients underwent RAPN in our hospital between October 2018 and May 2021. We excluded patients with CT images inappropriate for evaluation or for construction of 3D models, patients with multiple tumors, and those who underwent preoperative transcatheter arterial embolization. We conducted a retrospective analysis of the remaining patients using SPARE predictions from CT images (2D-SPARE) and SPARE predictions from 3D models (3D-SPARE). We evaluated the difference between the 2 nephrometry scores and compared them by their ability to predict the achievement of the desired surgical outcome: absence of positive margins, absence of ischemia, and absence of significant complications. RESULTS: A total of 87 patients were included in this study. Total score, and risk categorization using 3D-SPARE was significantly different from those using 2D-SPARE (P <.05), but in their areas under the curve (AUC), the scores and categorizations were not significantly different (score, 0.763 vs 0.742; P = .501; categorization, 0.711 vs 0.701; P = .755). CONCLUSION: The SPARE system can describe the surgical difficulty of renal masses with high accuracy even without the use of 3D renal models.

RESUMEN

Introduction: Tape infection after insertion of tension-free vaginal tape is a well-known but rare complication. We report a patient who experienced a subcutaneous abscess 19 years after the surgery. Case presentation: A 41-year-old woman presented with fever and lower abdominal pain. She had undergone tension-free vaginal tape insertion for stress urinary incontinence 19 years prior. She had asymptomatic dysuria. After an abscess incision and 1-week treatment with antibiotics, she underwent surgery to remove the tape and the abscess without complications. Conclusion: Tension-free Vaginal Tape insertion could be a potential risk of asymptomatic dysuria, resulting in urinary tract infection. In this case, removal of tape was necessary for controlling subcutaneous abscess resulting from the presence of tension-free vaginal tape.
