Abstract
INTRODUCTION Chronic radiation cystitis (CRC) can develop between 6 months and 20 years after radiation therapy that presents with symptoms of urinary frequency, urgency, bladder pain, and nocturia. Amniotic membrane (AM) is known to contain pro-regenerative properties and could thereby be a potential therapeutic modality for radiation-induced tissue injury of the bladder. MATERIALS AND METHODS CRC patients recalcitrant to previous treatments received amniotic bladder therapy (ABT) comprised of intra-detrusor injections of 100 mg micronized AM (Clarix Flo) diluted in 10 mL 0.9% preservative-free sodium chloride. Clinical evaluation and questionnaires (Interstitial Cystitis Symptom Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Bladder Pain/ Interstitial Cystitis Symptom Score (BPIC-SS), Overactive Bladder (OAB) Assessment Tool, and SF-12 Health Survey) were repeated at preop and 2, 4, 8 and 12 weeks post-injection. RESULTS Five consecutive female patients aged 64.4 ± 20.1 years with a median CRC disease duration of 10 years were included. After ABT, BPIC-SS scores improved from baseline to 12 weeks (36.6 ± 1.1 to 12.6 ± 3.1) and this was associated with an improvement in ICSI, ICPI, OAB, and SF-12 scores. One patient had an acute urinary tract infection at 2 weeks but was successfully treated with oral antibiotics. No other adverse events related to micronized AM injections were observed. Uroflow assessments showed increases in voided volume for all five patients. CONCLUSIONS This data provides additional evidence for the potential benefit of ABT in patients with chronic inflammatory conditions of bladder such as CRC.

Early three-month report of amniotic bladder therapy in patients with interstitial cystitis/bladder pain syndrome. Int Urol Nephrol 2023:10.1007/s11255-023-03652-8. [PMID: 37273012 DOI: 10.1007/s11255-023-03652-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 05/25/2023] [Indexed: 06/06/2023]
Abstract
BACKGROUND Interstitial cystitis/bladder pain syndrome (IC/BPS) is characterized by symptomatic frequency and urgency, as well as chronic pelvic pain. Disruption of the urothelial barrier is closely associated with IC/BPS. As amniotic membranes (AM) offer capabilities of wound healing in many other fields of medicine, likewise amniotic bladder therapy (ABT) may offer capability of urothelial healing in IC/BPS. METHODS Under general anesthesia, 10 consecutive IC/BPS patients received intra-detrusor injections of 100 mg micronized AM (Clarix Flo) diluted in 10 ml 0.9% preservative-free sodium chloride. Clinical evaluation and questionnaires (Interstitial Cystitis Symptom Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Bladder Pain/ Interstitial Cystitis Symptom Score (BPIC-SS), Overactive Bladder Assessment Tool, and SF-12 Health Survey) were repeated at pre-op and 2, 4, 8 and 12 weeks post-op. RESULTS Ten females (47.4 ± 14.4 years) who had recalcitrant IC/BPS for 7.8 years (5.2-12.1 years) received injection of micronized AM uneventful in all cases. After treatment, voiding symptoms and bladder pain significantly improved from pre-injection to 3 months. BPIC-SS significantly decreased from 37.4 ± 0.70 at baseline to 12.2 ± 2.90 at 3 months (p < 0.001). This corresponded to a significant improvement in their overall physical and mental quality of life. No adverse events occurred related to micronized AM injections, such as UTIs or acute urinary retention. CONCLUSION ABT could be an innovative treatment option for IC/BPS patients in terms of improving clinical symptoms based on preliminary outcomes at 3 months. Further studies are warranted to confirm the usefulness of ABT in patients with IC/BPS and to determine the duration of the effect.

Abstract
Carcinoma ex pleomorphic adenoma is a rare type of cancer of the salivary gland that involves the malignant transformation of a primary or recurrent pleomorphic adenoma, which often metastasises to the lungs or bones, or both. To the best of our knowledge, however, nobody has reported a distant metastasis of this lesion to the brain without such previous metastasis. We report a case in a 64-year-old man.

Abstract
Abstract
BACKGROUND:
The incidence rates of breast cancer (BC) in Asian counties have been rising rapidly. The age-specific female BC incidence rates peak before menopause (around 40-50 years of age) in Asia, however treatment options for pre/perimenopausal patients are limited. Palbociclib (P) is an oral novel cyclin-dependent kinase 4/6 (CDK4/6) inhibitor. The addition of P to endocrine therapy (ET) such as aromatase inhibitor or fulvestrant has been demonstrated improved progression-free survival (PFS) in phase 3 studies PALOMA-2 and PALOMA-3. This study is designed to evaluate efficacy and safety of P plus tamoxifen (TAM) in patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic BC regardless of menopausal status. This study is conducted as a Clinical Research Collaboration by National Cancer Center Hospital with research funding from Pfizer.
TRIAL DESIGN:
PATHWAY/NCCH1607 is a double-blind, placebo-controlled, randomized, phase 3 study. Patients will be randomized 1:1 to receive either P (125 mg once daily, days1-21 of a 28-day cycle) or placebo in combination with TAM (20 mg once daily, continuously). Pre/perimenopausal women should receive concurrent ovarian function suppression with goserelin. Randomization will be stratified by prior ET for advanced/metastatic BC (1st line ET vs. 2nd line ET) and menopausal status (pre/perimenopausal vs. postmenopausal).
KEY ELIGIBILITY CRITERIA:
Eligible patients include women of any menopausal status with HR-positive, HER2-negative advanced or metastatic BC; candidates to receive TAM as 1st line or 2nd line ET for advanced/metastatic disease; ≥18 years of age; measurable or non-measurable disease (RECIST v.1.1); ECOG performance status 0-1; adequate organ function; have not received treatment with TAM (except for patients who have had more than 12 months from completion of adjuvant therapy with TAM); and have not received any CDK4/6 or phosphoinositide 3-kinase (PI3K) - mammalian target of rapamycin (mTOR) inhibitors.
SPECIFIC AIMS:
The primary endpoint is PFS as assessed by the investigator. Secondary endpoints include overall survival (OS), 1, 2, and 3-year survival probabilities, objective response (OR), duration of response, clinical benefit rate (CBR), pharmacokinetics, safety, and patient-reported outcomes.
STATISTICAL METHODS:
The sample size was determined to detect a 38% reduction in the hazard of disease progression or death in P plus TAM arm with a 1-sided significance level of 2.5% and power of 80%. A stratified log rank test will be used to compare PFS between the 2 treatment arms.
PRESENT ACCRUAL AND TARGET ACCRUAL:
Target accrual of 180 patients will be enrolled within 23 sites among Japan, Korea, Taiwan, and Singapore. As of June 2018, 46 patients have been enrolled.
CONTACT INFORMATION:
This trial is registered at ClinicalTrials.gov NCT03423199 and UMIN000030816. For more information, email NCCH1607_office@ml.res.ncc.go.jp

In Vitro Cell Dev Biol Anim 2017; 53:810-817.

Abstract
Heparin-binding protein 17 (HBp17)/fibroblast growth factor-binding protein-1 (FGFBP-1) was first purified from medium conditioned by A431 cells for its capacity to bind to fibroblast growth factors 1 and 2 (FGF-1 and -2). Among FGF family members, FGF-2 is a potent mitogen for various cell types, including vascular endothelial cells, fibroblasts, and cancer cells such as oral squamous cell carcinoma (OSCC) cells. Besides being well known in bone metabolism, the active form of vitamin D3, i.e., 1α,25(OH)2D3 (1,25D3), was reported to have protective effects for heart disease and cancer. Previously, we reported that 1,25D3 inhibited HBp17/FGFBP-1 expression in OSCC cell lines through NF-κB inhibition (IκBα activation) and resulted in the inactivation of FGF-2. In this study, we examined the potential anti-tumor effect of ED-71, an analog of 1α,25(OH)2D3, for squamous cell carcinoma cells in vitro and in vivo. The cell lines used were OSCC cell lines (NA-HO-1-n-1 and UE-HO-1-u-1), established from oral cancer patients in our laboratory, and an epidermoid carcinoma/SCC cell line (A431). The growth assay in serum-free culture revealed that ED-71 inhibited the growth of the cancer cell lines in a dose-dependent manner. In addition, ED-71 suppressed HBp17/FGFBP-1 expression by inhibiting the NF-κB pathway as did 1,25D3. Furthermore, a luciferase reporter assay revealed that the promoter activity of HBp17/FGFBP-1 (region between -217 and +61) was down-regulated by ED-71. Oral administration of ED-71 significantly inhibited the growth of A431-derived tumors in athymic nude mice. Immunohistochemical analysis revealed that the expression of HBp17/FGFBP-1, FGF-2, CD31, and Ki-67 in the tumors of ED71-treated group was down-regulated in comparison to control. These results suggest that ED-71 possesses potential anti-tumor activity for SCCs both in vitro and in vivo. This compound may act directly on the tumor cells or on endothelial cells by modulating the tumor microenvironment.

Abstract
OBJECTIVES To examine symptomatology and microbiology of infected lymphocele (LC) post-robotic-assisted radical prostatectomy and pelvic lymph node dissection (PLND) and to assess for potential predictors for LC fluid culture positivity. Secondly, to provide general recommendations about use of select antimicrobial therapy. METHODS This was a single-center, IRB-approved, retrospective, case series review conducted between October 2008 and October 2014. Data included symptomatology, microbiology of symptomatic LC in men post-robotic prostatectomy and PLND. Those with infected LC were compared to those men with symptomatic LC in the absence of infection. RESULTS Symptomatic LC was seen in 7% of men, and among those, infected LC was seen in 42%. Infected LC cultures showed predominance of G+ cocci such as S. aureus, coagulase-negative Staphylococcus species, S. pyogenes, S. fecalis and S. viridans. Monomicrobial infection was seen in 85%. Multivariate logistic regression showed leukocytosis [Odds: 12.3, p = 0.03, 95% CI (1.2-125)] was significant predictor for culture positivity, whereas trend toward significance for factors such CT findings of thickened walls around the LC +/- air. CONCLUSIONS LC infection following PLND for prostate cancer is usually monomicrobial and caused by Gram+ cocci. GI tract and skin flora are the main habitat. High index of suspicion of infected LC is undertaken in the presence of leukocytosis, fever and abnormal CT findings. Based upon our local hospital antibiogram, combination of IV ampicillin/sulbactam and vancomycin is suggested as the best initial empiric therapy in treating these patients.

Abstract
Objective: To demonstrate a benefit in diminished adverse events such as hypotension and hematuria with gradual drainage of the bladder when compared to rapid decompression in patients with acute urinary retention (AUR) due to benign prostatic hyperplasia in a case–control study. Methods: Sixty-two patients matched our selection criteria presenting with AUR. They were divided into two groups – the first was managed by rapid drainage of the bladder, the second was managed by gradual drainage through a urethral catheter (The first 100 mL immediately evacuated, then the rest evacuated gradually over 2 h). Results: The mean age was 64.4 and 63.2 years in the first and second group, respectively. Diagnosed cause was benign hyperplasia of the prostate. Hematuria occurred in two patients in the first group and none in the second group. The two cases of hematuria were mild and treated conservatively. After the relief of the obstruction, the mean blood pressure was noticed to decrease by 15 mmHg and 10 mmHg in the first and second group, respectively, however, no one developed significant hypotension. Pain relief was achieved after complete drainage in the first group and after the evacuation of 100 mL in the second group. Conclusions: We conclude that there is no significant difference between rapid and gradual decompression of the bladder in patients with AUR. Hematuria and hypotension may occur after rapid decompression of the obstructed urinary bladder, but these complications are rarely clinically significant.

Abstract
OBJECTIVES Several researchers have reported the relationship between infertility in male and varicocele for so many years but the implication of varicocele in female patients is remains elusive. Here, we aim to examine the effects of unilateral varicose ovarian vein on antioxidant capacity and oocyte quality of rat ovary after the experimental creation of varicocele in female rats. MATERIALS AND METHODS In this study, thirty adult female albino rats were divided into three equal groups: Group 1 as the control group has 10 rats, Group 2 as the sham group has 10 rats and they underwent a sham operation and finally Group 3 has the varicocele group has 10 rats. Antioxidant assays for superoxide dismutase, glutathione peroxidase and catalase were performed using specific assay kits and gene expression for Bax, Bmp-15, Hsp-27 and Gdf-9 was done via real time PCR. RESULTS The adverse effects of the experimentally induced varicocele were reported and recorded on the left ovary compared to the right sided ovary (no varicocele induction) in the varicocele group. Real time PCR data shows that the expression of Gdf-9, Hsp-27 and Bmp-15 genes were all significantly reduced at p≤ 0.05. CONCLUSION The results of this study show that reduced gene expression of Bmp-15, Gdf-9 and Hsp-27, increased gene expression of bax and an imbalance between pro-oxidant/antioxidant ratio are few of the several mechanisms by which varicocele may lead to infertility in female.

Abstract
BACKGROUND Infertility affects an estimated 15% of couples globally, amounting to 48.5 million couples. Males are found to be solely responsible for 20-30% of infertility cases and contribute to 50% of cases overall. However, this number does not accurately represent all regions of the world. Indeed, on a global level, there is a lack of accurate statistics on rates of male infertility. Our report examines major regions of the world and reports rates of male infertility based on data on female infertility. METHODS Our search consisted of systematic reviews, meta-analyses, and population-based studies by searching the terms "epidemiology, male infertility, and prevalence." We identified 16 articles for detailed study. We typically used the assumption that 50% of all cases of infertility are due to female factors alone, 20-30% are due to male factors alone, and the remaining 20-30% are due to a combination of male and female factors. Therefore, in regions of the world where male factor or rates of male infertility were not reported, we used this assumption to calculate general rates of male factor infertility. RESULTS Our calculated data showed that the distribution of infertility due to male factor ranged from 20% to 70% and that the percentage of infertile men ranged from 2·5% to 12%. Infertility rates were highest in Africa and Central/Eastern Europe. Additionally, according to a variety of sources, rates of male infertility in North America, Australia, and Central and Eastern Europe varied from 4 5-6%, 9%, and 8-12%, respectively. CONCLUSION This study demonstrates a novel and unique way to calculate the distribution of male infertility around the world. According to our results, at least 30 million men worldwide are infertile with the highest rates in Africa and Eastern Europe. Results indicate further research is needed regarding etiology and treatment, reduce stigma & cultural barriers, and establish a more precise calculation.

Engaging practicing gynecologists in the management of infertile men. J Obstet Gynaecol India 2015; 65:75-87.

Abstract
In the modern era, contemporary management of male infertility has undergone groundbreaking changes with the introduction of new concepts, advanced testing, and therapeutic interventions. As practicing gynecologists are often the first physicians who encounter an infertile couple, it is essential that these clinicians are continuously updated about the new pearls and pitfalls of male infertility management. Semen analysis is commonly ordered by gynecologists. In 2010, the WHO released new cutoff reference values for the semen parameters adopting novel methodology, which has incited much debate. Reference values have been lowered in comparison with previous standards, with a direct clinical implication in decision-making strategies. Specialized sperm-function tests, such as sperm oxidative stress and sperm chromatin integrity assessments, became clinically available, thus offering an opportunity to better understand sperm dysfunctions concealed during routine semen analysis. Furthermore, the initial counseling of azoospermic men by an andrologically well educated gynecologist may alleviate the misconception and distress surrounding the false belief of sterility, and will clarify the available options of percutaneous and microsurgical sperm-retrieval techniques and assisted conception outcome. Regarding varicocele, which is commonly seen in infertile males, it is now clear that the best treatment option for infertile men with clinical varicocele is the microsurgical vein ligation. Natural conception is significantly improved after varicocelectomy, and recent data suggest that such treatment optimizes reproductive outcome of couples undergoing ICSI or micro-TESE sperm retrieval. Lastly, new therapeutic interventions, including oral antioxidant therapy and lifestyle modifications, have gained increasing attention, as they aid in alleviating male infertility.

Abstract
The question whether K⁺ depolarization is an appropriate experimental substitute for the physiological nutrient-induced depolarization of the β-cell plasma membrane was investigated using primary mouse β-cells and islets. At basal glucose 40 mM K⁺ induced a massive monophasic response, whereas 15 mM K⁺ had only a minimal insulinotropic effect, even though the increase in the cytosolic Ca²⁺ concentration ([Ca²⁺]i) was not inferior to that by 20 mM glucose. In voltage-clamp experiments, Ca²⁺ influx appeared as nifedipine-inhibitable inward action currents in the presence of sulfonylurea plus TEA to block compensatory outward K⁺ currents. Under these conditions, 15 mM K⁺ induced prolonged action currents and 40 mM K⁺ transformed the action current pattern into a continuous inward current. Correspondingly, 15 mM K⁺ led to an oscillatory increase and 40 mM K⁺ to a plateau of [Ca²⁺]i superimposed on the [Ca²⁺]i elevated by sulfonylurea plus TEA. Raising K⁺ to 15 or 40 mM in the presence of sulfonylurea (±TEA) led to a fast further increase of insulin secretion. This was reduced to basal levels by nifedipine or CoCl₂. The effects of 15 mM K⁺ on depolarization, action currents, and insulin secretion were mimicked by adding 35 mM Cs⁺ and those of 40 mM K⁺ by adding 35 mM Rb⁺, in parallel with their ability to substitute for K⁺ as permeant cation. In conclusion, the alkali metals K⁺, Rb⁺, or Cs⁺ concentration-dependently transform the pattern of Ca²⁺ influx into the β-cell and may thus generate stimuli of supraphysiological strength for insulin secretion.

Abstract
OBJECTIVE This study reports the findings of a Phase I/II, cohort, dose-escalation trial of amrubicin and irinotecan with the support of granulocyte colony-stimulation factor. This study aimed to determine the dose-limiting toxicity of the combination and to define the maximum-tolerated dose, as a recommended dose for Phase II trials. We also sought to obtain preliminary data on the efficacy of this combination as a frontline therapy for extensive-disease small-cell lung cancer. METHODS We included 23 chemo-naïve patients with extensive-disease small-cell lung cancer in the trial. The amrubicin dose was escalated from 35 to 40 mg/m(2) (Levels 1 and 2, respectively) to determine the dose-limiting toxicity, with an unchanged dose of irinotecan at 50 mg/m(2). RESULTS Of nine patients, three experienced dose-limiting toxicities at Level 1 of prolonged Grade 4 neutropenia, Grade 3 febrile neutropenia and Grade 3 febrile neutropenia with Grade 3 diarrhea. At Level 2, two patients experienced dose-limiting toxicities of Grade 4 neutropenia and Grade 3 neutropenia with Grade 4 diarrhea. The maximum-tolerated doses and recommended doses for amrubicin and irinotecan were therefore determined to be 35 and 50 mg/m(2), respectively. The Level 1 trial was then expanded to 21 patients, 14 (70%) of whom showed partial responses to the recommended dose. The median progression-free and overall survival times were 6.37 and 15.21 months, respectively. CONCLUSIONS The combination of amrubicin and irinotecan with the support of granulocyte colony-stimulation factor produced a potent effect in chemo-naïve extensive-disease small-cell lung cancer patients. The use of biomarkers for this regimen may identify patients who are likely to suffer from treatment-ending severe adverse effects.

Abstract
Unexplained male infertility is a diagnosis reserved for men in whom routine semen analyses results are within normal values and physical as well as endocrine abnormalities were ruled out. In addition to erectile problems and coital factors, immunologic causes and sperm dysfunction may contribute to such condition. New etiologies of unexplained male infertility include low level leukocytospermia and mitochondrial DNA polymerase gene polymorphism. Contemporary andrology may reveal cellular and sub-cellular sperm dysfunctions which may explain subfertility in such cases, thus aiding the clinician to direct the further work-up, diagnosis and counseling of the infertile male. The objective of this article is to highlight the concept of unexplained male infertility and focuses on the diagnosis and treatment of this condition in the era of modern andrology and assisted reproductive techniques. Extensive literature review was performed using the search engines: Pubmed, Science-direct, Ovid and Scopus.

Abstract
OBJECTIVE To identify the relative abundance of proteins in pooled reactive oxygen species (ROS)-positive (ROS+) and ROS-negative (ROS-) semen samples with the use of two-dimensional differential in-gel electrophoresis (2D-DIGE). DESIGN Spermatozoa suspensions from ROS+ and ROS- groups by 2D-DIGE analysis. SETTING Tertiary hospital. PATIENT(S) 20 donors and 32 infertile men. INTERVENTION(S) Seminal ejaculates evaluated for semen and proteomic analysis. MAIN OUTCOME MEASURE(S) Semen samples from 20 donors and 32 infertile men were pooled, divided into ROS+ and ROS- groups based on the cutoff value of <20 relative light units/s/10(6) sperm and frozen. From each pooled group, spermatozoa were labeled with Cy3/Cy5 fluorescent dye. Duplicate 2D-DIGE gels were run. Image analysis was performed with the use of Decider software. Protein spots exhibiting ≥1.5-fold difference in intensity were excised from the preparatory gel and identified by liquid chromatography-mass spectrometry. Data were analyzed with the use of Sequest and Blast programs. RESULT(S) A total of 1,343 protein spots in gel 1 (ROS-) and 1,265 spots in gel 2 (ROS+) were detected. The majority of protein spots had similar expression, with 31 spots were differentially expressed. Six spots were significantly decreased and 25 increased in the ROS- sample compared with the ROS+ sample. CONCLUSION(S) Significantly different expression of protective proteins against oxidative stress was found in ROS-compared with ROS+ samples. These differences may explain the role of oxidation species in the pathology of male infertility.

Abstract
Varicocele, the leading cause of male infertility, can impair spermatogenesis through several pathophysiological mechanisms. Of these, current evidence suggests that oxidative stress is the central element contributing to infertility in men with varicocele, to which the testis responds by way of heat stress, ischaemia or production of vasodilators, such as nitric oxide. Surgical varicocele repair (varicocelectomy) is beneficial not only for alleviating oxidative stress-associated infertility, but also for preventing and protecting against the progressive character of varicocele and its consequent upregulations of systemic oxidative stress. However, antioxidant therapy in infertile men with surgically treated and those with untreated varicocele is poorly studied, and well-designed trials are needed.
