- Abstract
Introduction: Hydronephrosis grading systems risk stratify patients with potential ureteropelvic junction obstruction, but only some criteria are measured objectively. Most notably, there is no consensus definition of renal parenchymal thinning., Objectives: The objective of this study was to assess the association between sonographic measures of renal length, renal pelvic diameter, and renal parenchymal thickness and the outcomes of a)renal hypofunction(differential renal function{DRF} <40%) and b)high-risk renal drainage(T1/2 > 40 min)., Study Design: An institutional database of patients who had diuretic renograms(DR) for unilateral hydronephrosis was reviewed. Only infants with Society for Fetal Urology(SFU) grades 3/4 hydronephrosis without hydroureter on postnatal sonogram and had a DR within 120 days were included. The following measurement variables were analyzed: anterior posterior renal pelvic diameter(APRPD), renal length(RL), renal parenchymal thickness(PT), minimal renal parenchymal thickness(MPT = shortest distance from mid-pole calyx to parenchymal edge), and renal pyramidal thickness(PyrT). RL, PT, MPT, PyrT measurements were expressed as ratios (hydronephrotic kidney/contralateral kidney). Multivariate logistic regression was performed for each outcome by comparing three separate renal measurement models. Model 1: RLR, APRPD, MPTR; Model 2: RLR, APRPD, PTR, Model 3: RLR, APRPD, PyrTR. Individual performance of variables from the best performing model were assessed via ROC curve analysis., Results: 196 patients were included (107 with SFU grade 3, 89 with SFU grade 4) hydronephrosis. Median patient age was 29[IQR 16,47.2] days. 10% had hypofunction, and 20% had T1/2 > 40 min 90% with hypofunction and 87% with high-risk drainage had SFU4 hydronephrosis. Model 1 exhibited the best performance, but on multivariate analysis, only APRPD and MPTR were independently associated with both outcomes. No other measure of parenchymal thickness reached statistical significance. The odds of hypofunction and high-risk drainage increase 10% per 1 mm increase in APRPD(aOR 1.1 [CI 1.03-1.2], p = 0.005; aOR 1.1 [CI 1.03-1.2], p = 0.003). For every 0.1unit increase in MPTR the odds of hypofunction decrease by 40%(aOR 0.6 [CI 0.4-0.9], p = 0.019); and the odds of high-risk drainage decrease by 30%(aOR 0.7 [CI 0.5-0.9], p = 0.011). Optimal statistical cut-points of APRPD >16 mm and/or MPTR <0.36 identified patients at risk for obstructive parameters on DR., Discussion and Conclusion: Of the sonographic hydronephrosis measurement variables analyzed, only APRPD and MPTR were independently associated with objective definitions of obstruction based on renal function and drainage categories. Patients who maintain APRPD <16 mm and/or MPTR >0.36 can potentially be monitored with renal sonograms as there is >90% chance that they will not have DRF<40% or T1/2 > 40 min., Competing Interests: Conflict of interest Neither I, nor any of the authors, have any conflicts of interest to disclose., (Copyright © 2024 Journal of Pediatric Urology Company.

- Abstract
Objective: To identify factors associated with overtreatment of presumed urinary tract infection (UTI) among children with spina bifida using such criteria., Study Design: A retrospective review of children with spina bifida (age <21 years) evaluated in the Emergency Department (ED) at a single institution was performed. Patients with a urinalysis (UA) performed who were reliant on assisted bladder emptying were included. The primary outcome was overtreatment, defined as receiving antibiotics for presumed UTI but ultimately not meeting spina bifida UTI criteria (≥2 urologic symptoms plus pyuria and urine culture growing >100k CFU/mL). The primary exposure was whether the components of the criteria available at the time of the ED visit (≥2 urologic symptoms plus pyuria) were met when antibiotics were initiated., Results: Among 236 ED encounters, overtreatment occurred in 80% of cases in which antibiotics were initiated (47% of the entire cohort). Pyuria with <2 urologic symptoms was the most important factor associated with overtreatment (OR 9.6). Non-Hispanic White race was associated with decreased odds of overtreatment (OR 0.3)., Conclusions: Overtreatment of presumed UTI among patients with spina bifida was common. Pyuria, which is not specific to UTI in this population, was the main driver of overtreatment. Symptoms are a cornerstone of UTI diagnosis among children with spina bifida, should be collected in a standardized manner, and considered in a decision to treat., Competing Interests: Declaration of Competing Interest No funding was secured for this study.

- Abstract
Objective: To review the evaluation and management of urologic pathology related to mitochondiral diseases (MD) in childhood., Methods: A retrospective review was performed of patients with MD from 1/1/2000 - 10/8/2020 who were referred for urologic evaluation at a single pediatric hospital. Clinical and demographic information was reviewed including symptomatology, urodynamic evaluation, and medical/surgical management., Results: 15 patients were identified for inclusion. Median age of presentation was 5 years and median follow up was 4 years. Patients presented with numerous urologic concerns including urinary retention/incomplete emptying, incontinence, and recurrent urinary tract infection. Urodynamics demonstrated elevated median bladder capacity at 172% of expected as calculated by age. Detrusor sphincter dyssynergia (DSD) was present in 6 (50%). Progression to surgical intervention occurred in 67% at a median time of 3.5 years after initial referral. This included suprapubic tube (SPT) placement and sacral neuromodulation (SNM)., Conclusion: Patients in this study were found to have a spectrum of lower urinary tract dysfunction (LUTD) with elevated bladder capacity being common. No singular urodynamic feature prevailed although DSD was found in 50%. Progression of symptoms over time was also common. Most patients (67%) did go on to surgical intervention including SPT and SNM. Clinicians should be aware of the possibility of LUTD in children with MD and they should be promptly referred to pediatric urology when LUTD is suspected., (Copyright © 2022 Elsevier Inc.

- Abstract
Purpose: This study aims to establish the ability of the Uroflex® external artificial sphincter to reduce the severity of male urinary incontinence and improve the quality of life of patients with male urinary incontinence., Methods: A pre-post pilot study was carried out on a sample of 30 patients with male urinary incontinence. Tolerability and satisfaction were assessed by comparing the results of the Pad test, and EQ-5D and KHQ questionnaires before and after 3 months of using Uroflex®., Results: At 3 months, 76.6% of patients continued using Uroflex®. The median score for overall satisfaction with the device was 8 out of 10. Pad test showed a significant reduction in the severity of male urinary incontinence at 3 months (p < 0.001), with resolution of all symptoms in 31% of patients. The KHQ showed a significant improvement in global quality of life (p = 0.003). This was also significant for five of the nine specific dimensions assessed. There was also an improvement in self-rated health using the EQ-5D questionnaire, although not significant (p = 0.075)., Conclusion: The Uroflex® external urinary sphincter seems to improve the severity of urinary incontinence and quality of life of patients with male urinary incontinence after prostate surgery. These encouraging results will need to be confirmed in larger controlled studies., (© 2024. The Author(s), under exclusive licence to Springer Nature B.V.)

Introduction: Urinary incontinence (UI), especially stress UI, is common after prostatectomy. Penile compression devices (PCDs) may be a safe, tolerable option for conservative management in men who are not candidates for or not interested in surgical intervention for their UI. Areas covered: This article examines the epidemiology of post-prostatectomy urinary incontinence (PPI), and options for management. All available studies on PCDs are explored, including those on biomechanics, safety, tolerability, and user experience. History, availability of PCDs, and areas for future development are discussed. Expert opinion: PCDs are an option for conservative management of PPI. They are recommended for those men without impairment in cognition, dexterity, or sensation. They should be worn for short periods of time and are best used during situations when incontinence might be precipitated. Overall, data suggest they are well tolerated and effective when tested, but large randomized comparative trials and studies of long-term use with relevant patient reported outcome measures are lacking. More studies are needed on commercially available PCDs. Biomechanical studies suggest that there are superior designs and materials both for efficacy and tolerability. With an aging population, and more older men going for prostate surgery, a larger market for these devices is likely. [ABSTRACT FROM AUTHOR]

Aims Bleeding events are a well-known complication of oral anticoagulant (OAC) use in patients with atrial fibrillation (AF). While these are undesirable, bleedings could have a warning potential for underlying tumoural lesions. Therefore, we aimed to investigate the association between anticoagulant-related bleeding and newly diagnosed tumoural lesions in a nationwide cohort study. Methods and results Using Belgian nationwide data, AF patients without any tumoural lesions were included when initiating OACs between 2013 and 2019. The absolute and relative risks of newly diagnosed tumoural lesions were investigated in OAC users with vs. without an OAC-related bleeding event. Analyses were additionally stratified by tumoural lesion, location-specific bleeding, and OAC type. A total of 230 386 OAC users were included, among whom 35 192 persons were diagnosed with a tumoural lesion during follow-up. Persons with a clinically relevant bleeding during OAC use had a tumoural lesion incidence of 15.33 per 100 person-years compared to an incidence of 5.22 per 100 person-years in persons without bleeding. Site-specific gastrointestinal, urogenital, respiratory, and intracranial bleeding events were respectively associated with a significantly increased risk of incident gastrointestinal [adjusted hazard ratio (aHR) 8.13 (95% confidence interval (CI): 7.08–9.34)], urological [aHR 12.73 (95% CI: 10.56–15.35)], respiratory [aHR 4.91 (95% CI: 3.24–7.44)], and intracranial tumoural lesions [aHR 27.89 (95% CI: 16.53–47.04)]. Conclusion Bleeding events in AF patients initiated on OAC were associated with an increased risk of tumoural lesions. Therefore, OAC-related bleeding events could unmask an underlying tumoural lesion. [ABSTRACT FROM AUTHOR]

Breast cancer is the most common cancer in women and the leading cause of female deaths by cancer in the world worldwide. Hence, understanding the molecular mechanisms associated with breast cancer development and progression, including drug resistance and breast cancer metastasis, is essential for achieving the best management of breast cancer patients. Cancer-related long noncoding RNAs have been shown to be involved in the regulation of each stage of breast cancer progression. Additionally, exosomes are extracellular microvesicles that are central to intercellular communication and play an important role in tumorigenesis. Exosomes can be released from primary tumor cells into the bloodstream and transmit cellular signals to distant body sites. In this work, we review the findings regarding the cellular mechanisms regulated by exosomal lncRNAs that are essentials to chemoresistance development and metastasis of breast cancer. Likewise, we evaluate the outcomes of the potential clinical use of exosomal lncRNAs as breast cancer biomarkers to achieve personalized management of the patients. This finding highlights the importance of transcriptomic analysis of exosomal lncRNAs to understand the breast cancer tumorigenesis as well as to improve the clinical tests available for this disease.

The narrow fraction of the cenospheres of coal fly ash (30−50 μm; glass phase ∼ 90 wt. %) was used for the preparation of β‐emitting 177Lu‐bearing aluminosilicate microspheres. Two methods of chemical modification to encapsulate 177Lu3+ in the cenosphere's aluminosilicate matrix were used, such as the formation of (i) microporous or (ii) meso/macroporous structure in the cenosphere shell followed by 175+176Lu3+ sorption. Conversion of Lu‐loaded microspheres into poorly soluble forms was performed via the thermal treatment at 900–1200°C and then 176Lu was transformed to 177Lu by neutron activation procedure in a nuclear reactor. The 176Lu‐bearing products were studied by PXRD, SEM, and EDX spectroscopy methods. It was established that the acid treatment of cenospheres resulting in a meso/macroporous structure in the cenosphere shell is the optimal nondestructive method to produce a microsphere precursor for Lu incorporation. The neutron activation of 176Lu‐bearing microspheres resulted in 177Lu‐microspheres that provide the specific radioactivity of 4.5 GBq/100 mg. The Lu leaching rate from 177Lu‐microspheres in a blood simulator determined according to the State Standard (GOST) R 52126‐2003 was about 10−6−10−7 g/cm2⋅day. [ABSTRACT FROM AUTHOR]

Purpose: The aim of our study was to investigate the comparative outcomes of five different energy types on surgical efficacy and postoperative recovery in patients with benign prostate hyperplasia. Methods: The literature was systematically reviewed on December 1st, 2023, encompassing studies retrieved from PubMed, Embase, Web of Science, and The Cochrane Library databases that incorporated clinical studies of holmium laser enucleation of the prostate (HoLEP), Thulium:YAG laser enucleation of the prostate (ThuLEP), transurethral plasmakinetic enucleation of prostate (PKEP), diode laser enucleation of the prostate (DiLEP) and thulium fiber laser enucleation of the prostate (ThuFLEP) in the treatment of prostatic hyperplasia. Two independent reviewers extracted study data and conducted quality assessments using the Cochrane Collaboration's Risk of Bias tool and Newcastle–Ottawa Scale (NOS). Network meta-analysis (NMA) was employed to indirectly analyze the outcomes of endoscopic enucleation of the prostate (EEP) techniques. Results: The study included a total of 38 studies, comprising 21 non-randomized controlled trials (nRCTs) and 17 randomized controlled trials (RCTs), incorporating five distinct techniques: holmium laser, Thulium:YAG laser, bipolar plasma, diode laser and thulium fiber laser. In comparing treatment durations, ThuLEP and HoLEP had shorter overall hospital stays than PKEP, while the enucleation time of ThuLEP and HoLEP was shorter than that of ThuFLEP. Moreover, the enucleation tissue weight of both thulium fiber laser and holmium laser was heavier than bipolar plasma. However, the analysis did not reveal any statistically significant variation in complications among the various types of enucleation. In postoperative follow-up, the IPSS at 3 months post-operation was superior in the Thulium:YAG laser group compared to the holmium laser group. The thulium fiber laser technique demonstrated significant advantages over other enucleation methods in terms of QoL and PVR at 12 months after surgery. Conclusion: Theoretical properties may vary among different energy sources; however, there are no discernible clinical differences in operation-related parameters, postoperative complications, and postoperative follow-up. Therefore, the choice of laser does not significantly impact the outcome. However, due to the limited number of included studies, future research should focus on larger sample sizes and multicenter investigations to further validate the findings of this study.

Introduction: Urological physiotherapy is an effective treatment for lower urinary tract disorders incurred by radical prostatectomy (RP), which significantly impair quality of life. The present study evaluates pelvic floor muscle function in patients who have undergone RP using ultrasound; it also analyses the factors impacting the effectiveness of urological physiotherapy. Material and methods: The medical records of 42 patients who underwent physiotherapy before RP were subjected to retrospective analysis. All received a standard examination of pelvic floor function utilizing ultrasound imaging and physiotherapy. Results: Thirty-six (86%) patients demonstrated an incorrect muscle reaction before physiotherapy, but fewer than 10% after physiotherapy. The median time between first consultation and radical prostatectomy was 9.3 months; this length of this period had a significant influence on the effects of physiotherapy (p < 0.01), but not on the functional state of the pelvic floor muscles (p = 0.47). Early commencement of exercises appears to increase the effectiveness of the physiotherapy. Conclusions: Ultrasound imaging is a useful tool for assessing pelvic floor muscle activity and for monitoring the cor- rectness of the performed exercises. Ultrasound imaging should be used during physiotherapy to provide a functional diagnosis of the pelvic floor muscles. [ABSTRACT FROM AUTHOR]

Gercek, O., Ulusoy, K., Yazar, V. M., and Topal, K.
- Abstract
Objective: This study is planned based on the hypothesis that if bladder cancer is detected early, the disease would be less advanced and the possibility of treatment will increase, at least the recurrence-free survival will be longer. Regarding this hypothesis, it is aimed to investigate the effect of delayed diagnosis primarily on the disease factors. Materials and methods: The study included 169 patients, who underwent TUR-BT with the suspicion of bladder cancer in the urology clinic of Afyonkarahisar Faculty of Medicine between April 2018 and April 2023. Demographic and clinical data of the patients were recorded and compared. Results: It was observed that the delay in diagnosis was significantly longer in patients with tumors larger than 3 cm compared to patients with tumors smaller than 3 cm (p < 0.001). In the correlation analysis between tumor size, duration of diagnosis delay, age, T stage, and tumor grade, a low level of positive correlation was observed between tumor size and duration of diagnosis delay, and it was statistically significant (r = 0.215, p = 0.005). Conclusion: In our study, it was shown that the tumor size increases as the duration of diagnosis delay increases and this increase causes an increase of 0.088 mm in the pathological size of the tumor in the 1-day delay period. Considering that tumor size changes the risk group of the disease in bladder tumors, and relatedly the follow-up and treatment process changes, we believe that these data will be valuable in the management of bladder cancer.

- Abstract
The transition toward renewable resources is pivotal for the sustainability of the chemical industry, making the exploration of biobased furanic platform chemicals derived from plant biomass of paramount importance. These compounds, promising alternatives to petroleum-derived aromatics, face challenges in terms of stability under synthetic conditions, limiting their practical application in the fuel, chemical, and pharmaceutical sectors. Our study presents a comprehensive evaluation of the stability of furan derivatives in various solvents and under different conditions, addressing the significant challenge of their instability. Through systematic experiments involving GC-MS, NMR, FT-IR and SEM analyses, we identified key degradation pathways and conditions that either promote stability or lead to undesirable degradation products. These findings demonstrate the strong stabilizing effect of polar aprotic solvents, especially DMF, and reveal the dependence of furan stability on solvent and additive type. This research opens new avenues in the utilization of renewable furans by providing critical insights into their behavior under synthetic conditions, significantly impacting the development of sustainable materials and processes. The broad appeal of this study lies in its potential to guide the selection of conditions for the efficient and sustainable synthesis of furan-based chemicals, marking a significant advance in green chemistry and materials science., (© 2024 Wiley-VCH GmbH.)

Simple Summary: Bladder cancer is the 10th most diagnosed cancer worldwide. The long non-coding RNA HOX transcript antisense intergenic RNA (HOTAIR) has been shown to play pivotal oncogenic roles in this type of cancer. The aim of this study was to determine the relevance of the HOTAIR rs920778 and rs12826786 genetic variants in bladder cancer susceptibility and prognosis. Our retrospective analyses using 106 bladder cancer patients and 199 cancer-free controls demonstrated that, despite not presenting an association with bladder cancer risk, HOTAIR rs920778 TT and rs12826786 CC genotypes are associated with a better prognosis for bladder cancer patients. The long non-coding RNA HOX transcript antisense intergenic RNA (HOTAIR) is associated with oncogenic features in bladder cancer and is predictive of poor clinical outcomes in patients diagnosed with this disease. In this study, we evaluated the impact of the HOTAIR single nucleotide polymorphisms rs920778 and rs12826786 on bladder cancer risk and survival. This case-control study included 106 bladder cancer patients and 199 cancer-free controls. Polymorphisms were evaluated through PCR-restriction fragment length polymorphism. The odds ratio and 95% confidence intervals were tested using univariable and multivariable logistic regressions. The effects on patient survival were evaluated using the log-rank test and Cox regression models. Our data showed that the HOTAIR rs920778 and rs12826786 genetic variants are not associated with the risk of developing bladder cancer. Nevertheless, survival analyses suggested that the HOTAIR rs920778 TT genotype and rs12826786 CC genotype are associated with increased survival in male bladder cancer patients and in patients, both male and female, who have primary tumors with a pathological stage of pT2. Together, these results suggest that, despite not being associated with bladder cancer risk, HOTAIR rs920778 and rs12826786 polymorphisms might represent new prognostic factors in this type of cancer. This is particularly important as these polymorphisms might be easily evaluated in bladder cancer patients in a minimally invasive manner to better predict their clinical outcomes.

Introduction: In contrast to the dynamics observed in plant/pathogen interactions, endophytic fungi have the capacity to establish enduring associations within their hosts, leading to the development of a mutually beneficial relationship that relies on specialized chemical interactions. Research indicates that the presence of endophytic fungi has the ability to significantly modify the chemical makeup of the host organism. Our hypothesis proposes the existence of a reciprocal exchange of chemical signals between plants and fungi, facilitated by specialized chemical processes that could potentially manifest within the tissues of the host. This research aimed to precisely quantify the portion of the cumulative fungal endophytic community's metabolome detectable within host leaves, and tentatively evaluate its relevance to the host-endophyte interplay. The understory palm Astrocaryum sciophilum (Miq.) Pulle was used as a interesting host plant because of its notable resilience and prolonged life cycle, in a tropical ecosystem. Method: Using advanced metabolome characterization, including UHPLCHRMS/MS and molecular networking, the study explored enriched metabolomes of both host leaves and 15 endophytic fungi. The intention was to capture a metabolomic "snapshot" of both host and endophytic community, to achieve a thorough and detailed analysis. Results and discussion: This approach yielded an extended MS-based molecular network, integrating diverse metadata for identifying host- and endophyte-derived metabolites. The exploration of such data (>24000 features in positive ionization mode) enabled effective metabolome comparison, yielding insights into cultivable endophyte chemodiversity and occurrence of common metabolites between the holobiont and its fungal communities. Surprisingly, a minor subset of features overlapped between host leaf and fungal samples despite significant plant metabolome enrichment. This indicated that fungal metabolic signatures produced in vitro remain sparingly detectable in the leaf. Several classes of primary metabolites were possibly shared. Specific fungal metabolites and/or compounds of their chemical classes were only occasionally discernible in the leaf, highlighting endophytes partial contribution to the overall holobiontmetabolome. To our knowledge, the metabolomic study of a plant host and its microbiome has rarely been performed in such a comprehensive manner. The general analytical strategy proposed in this paper seems well-adapted for any study in the field of microbial- or microbiomerelated MS and can be applied to most host-microbe interactions.

Background and Objectives: Urethral strictures are the most common complications after surgical treatments of benign prostatic hyperplasia (BPH). Despite various preventive measures, the search for medications with antiproliferative activity and the development of surgical procedures to prevent the development of urethral strictures are still relevant. We evaluated the preventive efficacy of 5-fluorouracil against urethral strictures in patients undergoing surgery for BPH. Materials and Methods: A non-randomized clinical trial including 246 male patients with an average age of 70.0 ± 8.0 years was conducted. The main study group included 124 patients who, in addition to the standard treatment, received lavage with a 5-fluorouracil solution (1000 mg/20 mL per 500 mL of 0.9% isotonic saline) using a modified three-way urethral catheter. The monitoring of clinical, laboratory, and instrumental parameters was carried out 10 days, 3 months, and 6 months after surgery. Results: The evaluation of severity for dysuria symptoms in patients using the IPSS scale throughout the entire follow-up period showed a statistically significant decrease in ischuria and stranguria, prolongation of the interval between urinations, a decrease in intermittent urination, urinary incontinence, and straining before urination in the main group in comparison with the control patients. The patients of both study groups noted an improvement in the quality of life. It was found statistically significant decrease in the maximum urinary flow rate in the main group (p < 0.001). In the control group, after three months, four cases of urethral strictures and stenosis were recorded; after six months, this rate reached nine cases (7.3%), while in the main group, only one patient with infravesical obstruction was found (0.8%) (χ
2 = 3.855, p < 0.05). Conclusions: The results of our study could indicate the effectiveness of the antiproliferative drug 5-fluorouracil in combination with use of a modified catheter in relation to the development of postoperative urethral strictures. [ABSTRACT FROM AUTHOR]- Published

Background: Bladder cancer (BLCA) research in Koreans is still lacking, especially in focusing on the prediction of BLCA. The current study aimed to discover metabolic signatures related to BLCA onset and confirm its potential as a biomarker. Methods: We designed two nested case-control studies using Korean Cancer Prevention Study (KCPS)-II. Only males aged 35–69 were randomly selected and divided into two sets by recruitment organizations [set 1, BLCA (n = 35) vs. control (n = 35); set 2, BLCA (n = 31) vs. control (n = 31)]. Baseline serum samples were analyzed by non-targeted metabolomics profiling, and OPLS-DA and network analysis were performed. Calculated genetic risk score (GRS) for BLCA from all KCPS participants was utilized for interpreting metabolomics data. Results: Critical metabolic signatures shown in the BLCA group were dysregulation of lysine metabolism and tryptophan-indole metabolism. Furthermore, the prediction model consisting of metabolites (lysine, tryptophan, indole, indoleacrylic acid, and indoleacetaldehyde) reflecting these metabolic signatures showed mighty BLCA predictive power (AUC: 0.959 [0.929–0.989]). The results of metabolic differences between GRS-high and GRS-low groups in BLCA indicated that the pathogenesis of BLCA is associated with a genetic predisposition. Besides, the predictive ability for BLCA on the model using GRS and five significant metabolites was powerful (AUC: 0.990 [0.980–1.000]). Conclusion: Metabolic signatures shown in the present research may be closely associated with BLCA pathogenesis. Metabolites involved in these could be predictive biomarkers for BLCA. It could be utilized for early diagnosis, prognostic diagnosis, and therapeutic targets for BLCA. [ABSTRACT FROM AUTHOR]

OTX homeobox genes have been extensively studied for their role in development, especially in neuroectoderm formation. Recently, their expression has also been reported in adult physiological and pathological tissues, including retina, mammary and pituitary glands, sinonasal mucosa, in several types of cancer, and in response to inflammatory, ischemic, and hypoxic stimuli. Reactivation of OTX genes in adult tissues supports the notion of the evolutionary amplification of functions of genes by varying their temporal expression, with the selection of homeobox genes from the "toolbox" to drive or contribute to different processes at different stages of life. OTX involvement in pathologies points toward these genes as potential diagnostic and/or prognostic markers as well as possible therapeutic targets. [ABSTRACT FROM AUTHOR]

Introduction: The large amount of intraoperative bleeding and the high incidence of postoperative hematuria are still common factors affecting the prostate surgery treatment effect. Our research aimed to observe the effect of prostatic enucleation using 1,470 nm semiconductor laser on the amount of bleeding in patients with different sizes of prostate hyperplasia. Methods: According to the size of the prostate, forty eligible patients with benign prostatic hyperplasia (BPH) were enrolled and divided into low and high volume group in this study. Hemoglobin decline, urinating condition, complications and erectile function were collected and compared before and after surgery. Results: Our data showed that hemoglobin decline was (10.0 ± 6.2) g/L and (12.1 ± 7.8) g/L, respectively for two group after surgery (P = 0.363). Urination was significantly improved following surgery in both groups of patients (P < 0.05), and no permanent urinary incontinence and sexual dysfunction and so no serious complications occurred. Conclusion: The above results suggested that prostatic enucleation using 1,470 nm semiconductor laser can be safe and effective for prostatic hyperplasia, and this surgery produced no significant effect on the amount of bleeding in whatever size of the prostate.

Background: Between 8 and 87% of prostatectomies result in urinary incontinence, with around half of patients using incontinence pads daily at 6 months. Specialist urology continence nurses at the Norfolk and Norwich University Hospitals (NNUH) NHS Foundation Trust created a pre- and post-surgical care pathway formalising support for these patients, which involves the provision of TENA Men (Essity) male incontinence pads. Aims: This audit aimed to assess patient satisfaction with this pathway and TENA Men pads. Methods: Patients who underwent a radical prostatectomy at NNUH between 27 April and 9 November 2021 and who required continence pads were invited to fill out an online anonymous mixed-method (mainly qualitative) survey. Results: Of 28 respondents, 71% reported incontinence after their surgical catheter was removed. Most (89%) were satisfied with the preoperative advice. Of 19 respondents to questions on confidence and satisfaction, 16 were confident that the pads they had been prescribed were helping them to manage urinary leakage, and 16 were confident or very confident that they could manage their incontinence themselves. Generally, respondents were confident that their overall and mental health had improved, and most were confident or very confident that they had less anxiety. However, less than a quarter of respondents were 'very confident' about going out, meeting people or exercising. All but one respondent found TENA Men pads easy to fit, and the most used words in the free-text explanations of what they most liked, included 'easy', 'discreet', 'comfortable' and 'unobtrusive'. Conclusion: The clinical pathway helped give patients undergoing radical prostatectomy confidence in their ability to manage post-surgery incontinence themselves and could be of value in other hospitals. Easy access to incontinence pads designed for the male anatomy has an important part in this. [ABSTRACT FROM AUTHOR]

Exosomes are lipid bilayer vesicles with a diameter of 40–100 nm secreted by almost all cells. They have been found play crucial regulatory roles in various diseases. With the development of exosomes engineering technology, exosome-based drug delivery has also rapidly evolved. Bladder cancer is a worldwide disease with high morbidity and recurrence but lack of funding, so it is also called Cinderella. Some explorations have demonstrated that exosomes are important in the development, prognosis, diagnosis and drug delivery of bladder cancer. With the rapid development of Mass spectrometry and next-generation sequencing, increasing numbers of differentially expressed molecules derived from exosomes have been found in bladder cancer. Exosomes and their contents are largely involved in bladder cancer progression, engineering of these exosomes with the targeted genes improves their potential for drug delivery of bladder cancer. Furthermore, exosomes and their contents are relate to many characteristics of bladder cancer. Herein, we briefly search 59 researches to explore the cargoes encapsuled in exosomes of bladder cancer patients. We also summarize the biogenesis, function, expression profiles, engineering approaches and biological mechanisms of exosomes and their contents for the diagnosis, prognosis and drug delivery for bladder cancer. We aim to make it clear whether exosomes are the glass slippers of Cinderella. [ABSTRACT FROM AUTHOR]

- Abstract
The direct C-H activation of inert C(sp
3 )-H bonds in a hydrocarbon chain has been a very attractive target in organic synthesis for many decades. Among all the variety of processes, those driven by vinyl carbocations are quite scarce thus far, and it is hard to control for unstabilized vinyl cations. In this study, we designed a double C(sp3 )-H functionalization of unactivated alkyl CH2 groups to produce a totally substituted quaternary carbon stereocenter via insertion of vinyl carbocations. These processes represent complicated reaction cascades with high molecular complexity controlled by the cooperative action of Ga(III) salts & GaHal4 - anions and allow one-step deep poly-functionalization of simple CH substrates to be performed. In practice, this concept was initially implemented with simple starting compounds such as alkyl acetylenes and activated cyclopropanes, alkenes, or cyclobutanes to construct norbornane, cyclopentatetralin, and other important skeletons., (© 2024.

- Abstract
Mechanochemical reactions by ball milling have opened new avenues in chemical synthesis. Particularly, mechanochemistry has facilitated the reaction of insoluble materials to simplify stablished synthetic protocols and develop new ones. One notable application involves the use of calcium carbide (CaC
2 ) as a C2 -synthon through mechanochemistry, which has offered a more practical alternative to incorporate C2 -units compared to the conventional use of highly flammable gaseous acetylene. For example, by ball milling, the acetylenic anions [C2 ]2- found in CaC2 have been harnessed for the synthesis of diverse functional carbon materials as well as discrete organic molecules. This Concept aims to contribute to the conceptualization of this innovative approach while highlighting both its advantages and the challenges inherent in the use of CaC2 ., (© 2024 Wiley-VCH GmbH.)- Published

- Abstract
Bladder cancer (BCa) is a highly prevalent type of cancer worldwide, and it is responsible for numerous deaths and cases of disease. Due to the diverse nature of this disease, it is necessary to conduct significant research that delves deeper into the molecular aspects, to potentially discover novel diagnostic and therapeutic approaches. Lately, there has been a significant increase in the focus on non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), due to their growing recognition for their involvement in the progression and manifestation of BCa. The interest in exosomes has greatly grown due to their potential for transporting a diverse array of active substances, including proteins, nucleic acids, carbohydrates, and lipids. The combination of these components differs based on the specific cell and its condition. Research indicates that using exosomes could have considerable advantages in identifying and forecasting BCa, offering a less invasive alternative. The distinctive arrangement of the lipid bilayer membrane found in exosomes is what makes them particularly effective for administering treatments aimed at managing cancer. In this review, we have tried to summarize different ncRNAs that are involved in BCa pathogenesis. Moreover, we highlighted the role of exosomal ncRNAs in BCa., (© 2024.

- Abstract
Urinary incontinence (UI) is prevalent and imposes significant social and economic burdens. This study reviews the literature on UI, assesses the current research status, and projects future trends. To visualize and analyze UI-related research, summarize and generalize the knowledge framework of the global UI field, and explore the current state of research and emerging trends, we conducted a comprehensive search of UI-related studies from 2014 to 2024 using the Web of Science Core Collection. Utilizing VOSviewer software, we mapped the scientific landscape and performed visual analytics on collaborative and co-citation networks, keyword co-occurrences, emergent clusters, and timeline mapping to elucidate the research dynamics. A total of 4326 publications were retrieved for further analysis. The United States ranked first in terms of the total number of publications, number of citations, and publication H-index. In terms of institutions, the University of California System had the most total citations and the highest H-index. Neurology and Urodynamics had the most articles published, the highest citation frequency, and the highest H-index. The author with the most citations and the highest average number of citations per article is Abrams P. The author with the highest H-index is Peyronnet B. Based on the keyword analysis, the articles were categorized into several main directions: epidemiological studies, diagnostic studies, treatment studies, female UI studies, and male UI studies. Epidemiology, treatment, and male UI are expected to continue as hot topics. This study demonstrates that UI research is more advanced in Europe and North America and that Neurourology and Urodynamics is the most influential journal in the field. In addition, epidemiology, treatment, and male UI will continue to be prominent topics. Our study contributes to a more comprehensive understanding of the current state of UI research and provides insights into future research directions in the field., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

A prototypical material for the oxidative coupling of methane (OCM) is Li/MgO, for which Li is known to be essential as a dopant to obtain high C2 selectivities. Herein, Li/MgO is demonstrated to be an effective catalyst for non‐oxidative coupling of methane (NOCM). Moreover, the presence of Li is shown to favor the formation of magnesium acetylide (MgC2), while pure MgO promotes coke formation as evidenced by solid‐state 13C NMR, thus indicating that Li promotes C−C bond formation. Metadynamic simulations of the carbon mobility in MgC2 and Li2C2 at the density functional theory (DFT) level show that carbon easily diffuses as a C2 unit at 1000 °C. These insights suggest that the enhanced C2 selectivity for Li‐doped MgO is related to the formation of Li and Mg acetylides. [ABSTRACT FROM AUTHOR]

Background: Urinary bladder cancer (UBC) is the most common malignancy affecting the urinary system. This study aimed to investigate the diagnostic value of combining DAPK methylation in urinary sediment and B ultrasound in the detection of recurrent UBC. Methods: A total of 1021 cases with primary UBC who underwent electrocision of bladder tumor through urethra were included in this study and followed up. Various parameters including B ultrasound, DAPK methylation in urinary sediment, examination of exfoliated cells in the urine, and cystoscopy were performed. The data collected was analyzed using the Kappa test, and receiver operating characteristic (ROC) curve was constructed to assess the diagnostic role in recurrent UBC. Results: Among the 1021 patients, 115 patients experienced recurrence confirmed by cystoscopy and biopsy within two years and were excluded from the study, resulting in an effective sample size of 906 primary UBC cases. The results of cystoscopy showed agreement with B ultrasound (Kappa = 0.785, P < 0.05), as well as with DAPK methylation in urinary sediment, and the combination of B ultrasound and DAPK methylation (Kappa = 0.517, P < 0.05, Kappa = 0.593, P < 0.05). The combination of B ultrasound with DAPK methylation yielded an area under the curve of 0.922, with a sensitivity of 92.86%, specificity of 91.63%, and a negative predictive value of 99.4%, suggesting that a negative result indicates a low risk of recurrence. Conclusion: The combination of DAPK methylation in urinary sediment with B ultrasound demonstrates high diagnostic performance for recurrent UBC. [ABSTRACT FROM AUTHOR]

The tumor microenvironment (TME) is complex and involves many different cell types that seemingly work together in helping cancer cells evade immune monitoring and survive therapy. The advent of single-cell sequencing has greatly increased our knowledge of the cell types present in the tumor microenvironment and their role in the developing cancer. This, coupled with clinical data showing that cancer development and the response to therapy may be influenced by drugs that indirectly influence the tumor environment, highlights the need to better understand how the cells present in the TME work together. This review looks at the different cell types (cancer cells, cancer stem cells, endothelial cells, pericytes, adipose cells, cancer-associated fibroblasts, and neuronal cells) in the bladder tumor microenvironment. Their impact on immune activation and on shaping the microenvironment are discussed as well as the effects of hypertensive drugs and anesthetics on bladder cancer. [ABSTRACT FROM AUTHOR]

The use of advanced preclinical models has become increasingly important in drug development. This is particularly relevant in bladder cancer, where the global burden of disease is quite high based on prevalence and a relatively high rate of lethality. Predictive tools to select patients who will be responsive to invasive or morbid therapies (chemotherapy, radiotherapy, immunotherapy, and/or surgery) are largely absent. Patient-derived and clinically relevant models including patient-derived xenografts (PDX), organoids, and conditional reprogramming (CR) of cell cultures efficiently generate numerous models and are being used in both basic and translational cancer biology. These CR cells (CRCs) can be reprogrammed to maintain a highly proliferative state and reproduce the genomic and histological characteristics of the parental tissue. Therefore, CR technology may be a clinically relevant model to test and predict drug sensitivity, conduct gene profile analysis and xenograft research, and undertake personalized medicine. This review discusses studies that have utilized CR technology to conduct bladder cancer research. [ABSTRACT FROM AUTHOR]

This study investigated the impact of the initial clinical presentation of bladder cancer on tumor characteristics. A cross-sectional, retrospective study was performed, and it involved 515 patients who underwent transurethral bladder cancer resection at the University Hospital Center Split between April 2019 and April 2023, excluding recurrent cases. The association between symptomatic versus asymptomatic presentation and bladder cancer characteristics was analyzed. A subgroup analysis compared tumor characteristics between patients with gross and microscopic hematuria. Multiple regression analyses revealed a significant association between symptomatic presentation and the detection of high-grade bladder cancer (OR 3.43, 95% CI 2.22–5.29, p < 0.001), concomitant CIS (OR 3.41, 95% CI 1.31–8.88, p = 0.012), T2 stage bladder cancer (OR 5.79, 95% CI 2.45–13.71, p < 0.001), a higher number of tumors (IRR 1.24, 95% CI 1.07–1.45, p = 0.005), and larger tumor size (B 1.68, 95% CI 1.19–2.18, p < 0.001). In the subgroup analysis, gross hematuria was associated with the detection of high-grade bladder cancer (OR 2.07, 95% CI 1.12–3.84, p = 0.020), T2 stage bladder cancer (OR 6.03, 95% CI 1.42–25.49, p = 0.015), and larger tumor size (B 1.8, 95% CI 0.99–2.6, p < 0.001). The identified associations between symptomatic presentation and unfavorable bladder cancer characteristics, likely attributed to early detection in asymptomatic cases, underscore the importance of additional research in the development of bladder cancer screening strategies.

A potential complication of pharmacotherapy for a given patient is the possibility of various side effects of drugs, which are manifested in many ways and constitute iatrogenic causes of diseases. Among the systemic side effects of drugs, there are also those involving the urinary tract, although these are less reported in the literature. The use of numerous drugs—especially of anticholinergics or drugs with anticholinergic potential, opioid analgesics, non-steroidal anti-inflammatory drugs, antidepressants, first-generation antipsychotics (classic neuroleptics) and selected cardiovascular drugs (beta-blockers, thiazides potassium-sparing diuretics, statins), as well as others—may increase the risk of developing urological disorders, such as urinary retention or incontinence, urinary tract infections, urolithiasis, erectile dysfunction in men and retroperitoneal fibrosis. The purpose of this paper is to characterise the abovementioned drug-induced disorders of the lower urinary tract on the basis of a non-systematic literature review. [ABSTRACT FROM AUTHOR]

Purpose: Stress urinary incontinence (SUI) is a well-known adverse outcome following robotic-assisted laparoscopic prostatectomy (RALP). Although postoperative SUI has been extensively studied, little focus has been placed on understanding the natural history and impact of urgency symptoms following RALP. The UVA prostatectomy functional outcomes program (PFOP) was developed to comprehensively assess and optimize continence outcomes following RALP. The present study focuses on assessing urgency outcomes in this cohort. Methods: PFOP patients with a minimum of 6-months follow up following RALP were included. The PFOP includes prospectively assessed incontinence and quality of life outcomes utilizing ICIQ-MLUTS, Urgency Perception Score (UPS), and IIQ-7 questionnaires. The primary study outcome was urgency urinary incontinence (UUI) as determined by ICIQ-MLUTS UUI domain. Secondary outcomes included urgency (UPS score) and quality of life (IIQ-7). Results: Forty patients were included with median age 63.5 years. Fourteen (35%) patients reported UUI at baseline. UUI and QOL scores worsened compared to baseline at all time-points. Urgency worsened at 3-weeks and 3-months but returned to baseline by 6-months. Notably, 63% of patients without baseline UUI reported de-novo UUI at 6 months. Although QOL was lower in patients with versus without UUI (IIQ-7 score 3.0 vs 0.0, p = 0.009), severity of UUI was not associated with QOL when controlling for SUI severity. Conclusion: Our data demonstrate significantly worsened UUI from baseline and a large incidence of de-novo UUI following RALP. Further study is needed to inform how urgency and UUI and its treatment affect health-related quality of life following RALP. [ABSTRACT FROM AUTHOR]

Bladder cancer (BLCA) is one of the most common types of malignant tumors of the urogenital system in adults. Globally, the incidence of BLCA is more than 500,000 new cases worldwide annually, and every year, the number of registered cases of BLCA increases noticeably. Currently, the diagnosis of BLCA is based on cystoscopy and cytological examination of urine and additional laboratory and instrumental studies. However, cystoscopy is an invasive study, and voided urine cytology has a low level of sensitivity, so there is a clear need to develop more reliable markers and test systems for detecting the disease with high sensitivity and specificity. Human body fluids (urine, serum, and plasma) are known to contain significant amounts of tumorigenic nucleic acids, circulating immune cells and proinflammatory mediators that can serve as noninvasive biomarkers, particularly useful for early cancer detection, follow-up of patients, and personalization of their treatment. The review describes the most significant advances in epigenetics of BLCA. [ABSTRACT FROM AUTHOR]

The epithelial-to-mesenchymal transition (EMT) is a trans-differentiation process that endows epithelial cells with mesenchymal properties, including motility and invasion capacity; therefore, its aberrant reactivation in cancerous cells represents a critical step to gain a metastatic phenotype. The EMT is a dynamic program of cell plasticity; many partial EMT states can be, indeed, encountered and the full inverse mesenchymal-to-epithelial transition (MET) appears fundamental to colonize distant secondary sites. The EMT/MET dynamics is granted by a fine modulation of gene expression in response to intrinsic and extrinsic signals. In this complex scenario, long non-coding RNAs (lncRNAs) emerged as critical players. This review specifically focuses on the lncRNA HOTAIR, as a master regulator of epithelial cell plasticity and EMT in tumors. Molecular mechanisms controlling its expression in differentiated as well as trans-differentiated epithelial cells are highlighted here. Moreover, current knowledge about HOTAIR pleiotropic functions in regulation of both gene expression and protein activities are described. Furthermore, the relevance of the specific HOTAIR targeting and the current challenges of exploiting this lncRNA for therapeutic approaches to counteract the EMT are discussed. [ABSTRACT FROM AUTHOR]

There is little research on why smaller ethnic groups with no political stakes in the conflict take part in civil wars. There is even less understanding as to why members of small ethnicities join ideologically distant conflict participants to fight against an enemy that does not directly threaten their ethnic security. This study describes these ethnic minority combatants as "unlikely recruits." It argues that members of politically irrelevant minorities join stronger conflict participants—either governments or rebels—seeking to protect their ethnic interests from both their prospective hosts and their foes. Although the "unlikely recruits" have minimal grievances against enemies of their hosts and they receive limited participation rewards, forging an alliance with an actor which is likely to offer the highest benefits is sufficient to overcome the collective action problem. Recruiting members of smaller ethnic minorities in the context of ethnic civil wars allows armed actors to strengthen their image of ethnic diversity and all-inclusiveness, as well as to benefit from material resources provided by the "unlikely recruits." These arguments are empirically tested using new evidence from Ukraine that offers a rare glimpse into the dynamics of politically irrelevant minorities' participation in civil wars.

Ligustilide (LIG), the bioactive constituent of Angelica sinensis, may exert potential benefits in cancer treatment. However, the potential mechanism of LIG in the suppression of bladder cancer (BC) has not been reported yet. This study uncovered the inhibitory effect of LIG on the proliferation and cell cycle arrest of BC cells (T24 and EJ‐1) along with unveiling the underlying molecular mechanism. The IC50 values of LIG‐treated T24 for 24 and 48 h are 39.91 μg/mL (209.8 μM) and 40.94 μg/mL (215.2 μM) separately. The same conditions, the IC50 values of EJ‐1 are 45.73 μg/mL (240.4 μM) and 43.81 μg/mL (230.3 μM), separately. Additionally, LIG induced apoptosis and cycle arrest of T24 and EJ‐1 cells in sub‐G1 phase. Further studies showed that LIG induced apoptosis of BC cells by upregulating Caspase‐8, truncated BID (tBID) and BAX proteins, and downregulating NFκB1 (p50) protein. In conclusion, LIG significantly inhibits the growth of BC cells in vitro and in vivo by inducing apoptosis and is inexpensive, making it a promising candidate for novel anti‐BC drugs.
