vity, however further scientific evidence is essential to validate its potency in disease models associated with inflammation and cancer. There is limited information available for toxicity profiling of acacetin; therefore, further studies would aid in establishing this natural flavone as a potent candidate for research studies at clinical setup.Amyloid of the ureter is a rare disease with less than 25 cases reported in the literature. Despite being rare, it remains an important entity as it is typically confused with a primary neoplastic process of the urinary system. We report a case of a 68-year-old male with a history of cutaneous amyloid with late presentation of bilateral ureteral involvement.Dihydrotestosterone synthesis in prostate cancer from adrenal DHEA/DHEA-sulfate requires enzymatic conversion in tumor tissues. 3β-hydroxysteroid dehydrogenase-1 is an absolutely necessary enzyme for such dihydrotestosterone synthesis and is encoded by the gene HSD3B1 which comes in 2 functional inherited forms described in 2013. The adrenal-permissive HSD3B1(1245C) allele allows for rapid dihydrotestosterone synthesis. #link# The adrenal-restrictive HSD3B1(1245A) allele limits androgen synthesis. Studies from multiple cohorts show that adrenal-permissive allele inheritance confers worse outcomes and shorter survival after castration in low-volume prostate cancer and poor outcomes after abiraterone or enzalutamide treatment for castration-resistant prostate cancer. Here, we review the clinical data and implications.
To review the literature regarding the epidemiology of stone disease and develop a management algorithm based on current evidence and societal guidelines.
A structured literature review was performed to determine highest quality of evidence guiding care for pregnant patients with symptomatic nephrolithiasis. PUBMED and EMBASE databases were searched using terms "pregnancy," "nephrolithiasis," or "pregnancy" and "renal colic" alone and in combination with "stone", "kidney stone," "ultrasound," "MRI," "CT," "percutaneous nephrostomy," "ureteral stent," or "ureteroscopy." All English-language abstracts were reviewed for relevance and full-length articles were reviewed for content. link2 Articles published prior to 1990 were excluded, and priority for inclusion was given to multi-institutional studies and larger institutional studies, reflecting the highest level of current available evidence and most contemporaneous practice patterns.
Symptomatic nephrolithiasis affects less than 1% of pregnancies but poses unique diagnostic challenges due to the physiologic changes of pregnancy and risks of ionizing radiation exposure to the fetus. Ultrasound remains the imaging modality of choice. Most patients may be managed non-operatively, but drainage with percutaneous nephrostomy or ureteral stent may be performed if warranted. Growing evidence also supports the safety and efficacy of definitive stone treatment.
Though rare, symptomatic nephrolithiasis poses significant clinical challenges due to the need to minimize risk for both mother and fetus with diagnostic and therapeutic interventions. link3 A multi-disciplinary approach is paramount, as is shared decision making with the patient at each step of care.

To study the correlation between a new visual tool (ANalogical UroFlowmetry (ANUF)) and uroflowmetry (UF) parameters when performed to assess male lower urinary tract symptoms (MLUTS).
We configured an original pictogram composed of 4 different urine streams. In the setting of a University Hospital based prospective study where 545 men were enrolled between September 2018 and January 2019. Variables collected were age, UF pattern, Qmax, average flow rate (Qave), voided volume, postvoid residual, and selected image. The Spearman's rank test, ANOVA, and Tukey test, as well as the lineal regression model were used.
A total of 358 patients fulfilled the inclusion criteria. Mean age was 64.6 ± 12 years. Mean value and standard deviationfor the Qmax were 20.4 ± 10.5 mL/s for Image1; 15.5 ± 6.4 mL/s for Image2; 13.5 ± 6.0 mL/s for Image3 and 10.4 ± 5.4 mL/s for Image4. Statistically significant negative correlations were found between ANUF and Qmax (r=-0.317; P<.0001), and ANUF and Qave (r=-0.305; P<.0001). Qmax mean values among images were statistically different when compared in pairs, except Image1 and Image2 (P= .153). The confidence intervals calculated through the lineal regression model for the Qmax and each image were Image1) 17.8, confidence interval [CI] 95% [14.9-21.5] mL/s; Image2) 14.3, CI 95% [13.0-15.7] mL/s; Image3) 12.3, CI 95% [11.5-13.1] mL/s and Image4) 9.1, CI 95% [8.1-10.3] mL/s.
According to our results, ANUF is a useful and inexpensive tool presenting a correlation with the Qmax as well a correspondence of each image with a range of Qmax and its mean value.

To utilize a national dataset to compare outcomes and demonstrate trends in treatment for lymph node positive bladder cancer (N+ BC).
The National Cancer Database (2006-2014) was queried for cT2-4N1-3M0 N+ BC patients treated with radical cystectomy alone (RC), neoadjuvant chemotherapy (NAC), adjuvant chemotherapy (AC), chemoradiation (CRT), chemotherapy alone (CT), or no definitive treatment (NT). Survival by treatment was analyzed using Kaplan-Meier and multivariable Cox-proportional hazards regression. Pathologic down-staging was analyzed using univariable and multivariable logistic regression models. A univariable logistic regression model of treatment by year identified treatment trends.
Among 3241 patients (cN1, 46%; cN2, 44%; cN3 10%), the majority underwent combined chemotherapy and RC (NAC, 418; AC, 591; RC, 567; CRT, 392; CT, 1068; NT, 205). Overall survival did not differ between NAC and AC, but both had improved survival compared to RC. All other treatment groups had worse survival outcomes compared to NAC. Down-staging to pT0 (adjusted odds ratio = 26.39) and pN0 (adjusted odds ratio = 6.88) was higher for NAC than RC. Utilization of NAC has increased, AC and RC has declined, and CRT and NT is unchanged.
Combined chemotherapy and RC demonstrates best survival outcomes for N+ BC, with complete pathologic response to pT0N0 after NAC associated with a 5-year overall survival rate of ∼85%. However, there is no significant difference between NAC and AC. CRT is associated with worse oncologic outcomes compared to RC with perioperative chemotherapy, but improved survival compared to RC or CT.

However, one important limitation faced by members of these consortia and other renal pathologists and nephrologists in both investigative work and routine practice remains a lack of uniformity and precision in clearly defining the morphologic lesions on which the scoring systems are based. In response to this issue, the Renal Pathology Society organized a working group to identify the most frequently identified glomerular lesions observed by light microscopy and electron microscopy, review the literature to capture the published definitions most often used for each, and determine consensus terms and definitions for each lesion in a series of online and in-person meetings. The defined lesions or abnormal findings are not specific for any individual disease or subset of diseases, but rather can be applied across the full spectrum of glomerular diseases and within the context of the different scoring systems used for evaluating and reporting these diseases. In addition to facilitating glomerular disease research, standardized terms and definitions should help harmonize reporting of medical kidney diseases worldwide and lead to more-precise diagnoses and improved patient care.The complications of Alzheimer's disease (AD) have made the development of its treatment a challenging task. Several studies have indicated the disruption of insulin receptor substrate-1 (IRS-1) signaling during the development and progression of AD. The role of a dipeptidyl peptidase-4 (DPP-4) inhibitor on hippocampal IRS-1 signaling has not been investigated before. In this study, we evaluated the efficacy of alogliptin (DPP-4 inhibitor) on hippocampal insulin resistance and associated AD complications. In the present study, amyloid-β (1-42) fibrils were produced and administered intrahippocampally for inducing AD in Wistar rats. After 7 days of surgery, rats were treated with 10 and 20 mg/kg of alogliptin for 28 days. Morris water maze (MWM) test was performed in the last week of our experimental study. Post 24 h of final treatment, rats were euthanized and hippocampi were separated for biochemical and histopathological investigations. In-silico analysis revealed that alogliptin has a good binding affinity with Aβ and beta-secretase-1 (BACE-1). Alogliptin significantly restored cognitive functions in Aβ (1-42) fibrils injected rats during the MWM test. Alogliptin also significantly attenuated insulin level, IRS-1pS307 expression, Aβ (1-42) level, GSK-3β activity, TNF-α level and oxidative stress in the hippocampus. The histopathological analysis supported alogliptin mediated neuroprotective and anti-amyloidogenic effect. Immunohistochemical analysis also revealed a reduction in IRS-1pS307 expression after alogliptin treatment. The in-silico, behavioral, biochemical and histopathological analysis supports the protective effect of alogliptin against hippocampal insulin resistance and AD.The synthesis and characteristics of functional polyesters with a potential anticancer activity have been described, followed by a post-modification process of biologically active polymers. First, biodegradable functional polysuccinates possessing pendant allyl groups, that are susceptible to thiol-ene reaction, were obtained by polyaddition of succinic anhydride and allyl glycidyl ether. The functionality of such polyesters was regulated by replacing a part of unsaturated glycidyl ether with saturated ones. Polymers containing 20-100% mers with allyl groups were reacted with N-acetyl-cysteine (NAC). The use of simple click reaction allowed obtaining polyesters containing different amounts of N-acetyl-cysteine in side chains. The thus obtained polymers with a molecular weight of several thousand are characterized by solubility in methanol as opposed to their initial precursors. Modified polyesters show no toxicity to normal human keratinocytes (HaCaT) cells, similar to the NAC in normal human fibroblasts (NHDF), whereas the anticancer activities were observed against squamous carcinoma (SCC-25), and melanoma (Me45) cells.
