Abstract
INTRODUCTION Botulinum toxin A (BoNT-A) injections in the prostate gland have been used as a minimally invasive option for treating bladder outlet obstruction (BOO). However, the efficacy of transurethral BoNT-A injections for BOO is not well established in the literature. The aim of this study is to collect evidence on the efficacy of transurethral BoNT-A injections for the treatment of BOO. MATERIALS AND METHODS This systematic review and meta-analyses was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. A systematic literature search was performed till December 2022. The study population consisted of adult patients diagnosed with BOO, who underwent transurethral injections of BoNT-A for the treatment of BOO. EVIDENCE SYNTHESIS Out of 883 records, we identified seven studies enrolling 232 participants, of which only one nonrandomized controlled trial was found. Four prospective studies and two retrospective studies. Three studies included patients with lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH) and were included in the meta-analysis. Three studies included patients with urethral sphincter hyperactivity. One study included patients with primary bladder neck disease (PBND). All studies showed significant improvements from baseline in maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and postvoid residual (PVR) at 3 and 6 months. The adverse events were mild in all studies. Hematuria, UTI, and urinary retention were reported across all studies. CONCLUSION In conclusion, transurethral BoNT-A injections have been shown to improve LUTS, QoL, and urodynamic parameters of individuals with BOO at 3 and 6 months after injections, and no serious adverse effects have been reported. However, data on the long-term benefits of this treatment are scarce, and more prospective, randomized studies with larger samples examining various injection techniques, dosages, and extended follow-up of recurrent injections are needed.

Abstract
Urinary tract infections (UTIs) present a formidable challenge in the care of individuals affected by multiple sclerosis (MS). Lower urinary tract dysfunction is a prevalent issue among MS patients, predisposing them to an elevated risk of UTIs. When left untreated, UTIs can further exacerbate the already compromised quality of life in individuals with MS. The diagnosis and management of UTIs in MS patients necessitate a careful clinical evaluation. The objective of this review is to delineate preventive strategies and current and developing therapeutic approaches for preventing and treating UTIs associated with urinary dysfunction, catheterization, and upper urinary tract infections in patients with MS. Effectively addressing UTIs and urinary tract dysfunction in individuals with multiple sclerosis calls for a comprehensive, interdisciplinary approach.

Abstract
BACKGROUND Since 2014, a new residency program selection process has been established with a national examination. The aim of this study was to assess characteristics, career goals, and practice preferences of current Italian urology residents. METHODS A web-based survey of 25 items performed from May 2021 to September 2021 was sent to 585 Italian urology residents. Descriptive analyses were conducted to describe the surveys' domains: demographics characteristics, studies, plans for fellowship training, interest in the urology field, and career expectations. RESULTS Four hundred and one residents completed the online survey (response rate 68.5%). Most residents were male (70.3%), with a median of 29 (IQR 28-31) years. Urology was the first chosen School in 325 (81.0%) cases, and 174 (43.4%) trainees have chosen to remain in the same University. Uro-oncology was the main field, and endourology the main subspeciality of interest, respectively. More than 40.0% of residents expressed a good level of satisfaction for the training urological course. 232 (57.2%) residents were strongly interested in seeking a hospital career, followed by private career (43.4%) and academic career (20%). CONCLUSIONS After the introduction of the novel national residency matching program the Italian Urology trainees showed a good satisfaction level. Further improvements of the Italian residency programs should be focused on the training network within and outside the main School of Urology.

Abstract
Multiple sclerosis (MS) is the most frequent neurological disease in young adults, with the greatest incidence between age of 30 and 35 years. Sexual dysfunctions (SDs) are frequent, but are often underestimated in patients with MS, and can have a significantly high impact on patient's quality of life. Aim of this review is to summarize sexual dysfunctions in male and female MS patients and to illustrate current and emerging therapeutic options for treatment.

Abstract
Everyone talks about the metaverse but few know what it really is. Augmented reality, virtual reality, internet of things (IoT), 5G, blockchain: these are just some of the technologies underlying the structure of the metaverse, a sort of parallel dimension in which the physical and virtual worlds merge together enabling users to interact by emerging technologies in order to enhance their actions and decisions. The healthcare scientific community is already looking at the metaverse as a new research frontier, a tool to improve medical knowledge and patient care. We reviewed the metaverse applications and services, looking for those that could best be developed in the urological field. Urology, due to its technological nature, is a privileged laboratory for experimenting and exploiting the applications of the metaverse both inside and outside the operating room. The revolution of the metaverse is already happening, which is why it is necessary that urologists face it as protagonists in order to lead it in the right direction.

Abstract
The artificial urinary sphincter (AUS) implantation is an effective treatment of post-prostatectomy urinary incontinence (PPI). Still, it may result in troublesome complications such as intraoperative urethral lesion and postoperative erosion. Based on the multilayered structure of the tunica albuginea of the corpora cavernosa, we evaluated an alternative transalbugineal surgical technique of AUS cuff placement with the aim to decrease perioperative morbidity while preserving the integrity of the corpora cavernosa. A retrospective study was conducted in a tertiary referral center from September 2012 to October 2021, including 47 consecutive patients undergoing AUS (AMS800®) transalbugineal implantation. At a median (IQR) follow-up of 60 (24-84) months, no intraoperative urethral injury and only one noniatrogenic erosion occurred. The actuarial 12 mo and 5 yr overall erosion-free rates were 95.74% (95% CI: 84.04-98.92) and 91.76% (95% CI: 75.23-97.43), respectively. In preoperatively potent patients, the IIEF-5 score remained unchanged. The social continence (0-1 pads per day) rate was 82.98% (CI 95%: 68.83-91.10) at 12 mos and 76.81% (CI 95%: 60.56-87.04) at 5 yrs follow-up. Our technically refined approach to AUS implantation may help to avoid intraoperative urethral lesions and lower the risk of subsequent erosion without compromising sexual function in potent patients. Prospective and adequately powered studies are necessary to achieve more compelling evidence.

Abstract
The subtle interplay between the inter-molecular interactions established by catechol with the surrounding solvent and the intra-molecular hydrogen bond (HB) characterizing its conformational dynamics is investigated through a multi-level computational approach. First, quantum mechanical (QM) calculations are employed to accurately characterize both large portions of the catechol's potential energy surface and the interaction energy with neighboring solvent molecules. The acquired information is thereafter exploited to develop a QM derived force-field (QMD-FF), in turn employed in molecular dynamics (MD) simulations based on classical mechanics. The reliability of the QMD-FF is further validated through a comparison with the outcomes of ab initio molecular dynamics, also purposely carried out in this work. In agreement with recent experimental findings, the MD results reveal remarkable differences in the conformational behavior of isolated and solvated catechol, as well as among the investigated solvents, namely water, acetonitrile or cyclohexane. The rather strong intramolecular HB, settled between the vicinal phenolic groups and maintained in the gas phase, loses stability when catechol is solvated in polar solvents, and is definitively lost in protic solvents such as water. In fact, the internal energy increase associated with the rotation of one hydroxyl group and the breaking of the internal HB is well compensated by the intermolecular HB network available when both phenolic hydrogens point toward the surrounding solvent. In such a case, catechol is stabilized in a chelating conformation, which in turn could be very effective in water removal and surface anchoring. Besides unraveling the role of the different contributors that govern catechol's conformational dynamics, the QMD-FF developed in this work could be in future employed to model larger catechol containing molecules, due to its accuracy to reliably model both internal flexibility and solvent effects, while exploiting MD computational benefits to include more complex players as for instance surfaces, ions or biomolecules.

Abstract
Background: To date, robotic surgery in urology is well established all over the world. The newest platform on the market is the HUGO™ RAS system, developed by Medtronic. In this paper we provide a brief description of the system and describe our system set-up and surgical approach with this new platform in our initial experience of robotic radical prostatectomy (RARP) series. Materials and methods: After an official training, seven consecutive patients affected by localized prostate cancer underwent RARP with HUGOTM RAS system at our Institution. A description of our surgical approach and docking setup is provided. Docking and console times were reported for all precedures together with main suggestions to facilitate the use of this new system at the beginning of the experience. Results: Our operating room setup has shown to be safe, effective, and easy replicable. During our series, operative times appeared to be easy reproducible and comparable to those obtained with daVinci system. No major system faults and conflicts between robotic arms were observed after the first procedure. Conclusions: Our surgical approach and system configuration for performing RARP with the new HUGO™ RAS system appears to be safe, efficient and easy reproducible.

Abstract
Transition Metal Complexes (TMCs) are known for the rich variety of their excited states showing different nature and degrees of locality. Describing the energies of these excited states with the same degree of accuracy is still problematic when using time-dependent density functional theory in conjunction with the most current density functional approximations. In particular, the presence of unphysically low lying excited states possessing a relevant Charge Transfer (CT) character may significantly affect the spectra computed at such a level of theory and, more relevantly, the interpretation of their photophysical behavior. In this work, we propose an improved version of the MAC index, recently proposed by the authors and collaborators, as a simple and computationally inexpensive diagnostic tool that can be used for the detection and correction of the unphysically predicted low lying excited states. The analysis, performed on five prototype TMCs, shows that spurious and ghost states can appear in a wide spectral range and that it is difficult to detect them only on the basis of their CT extent. Indeed, both delocalization of the excited state and CT extent are criteria that must be combined, as in the MAC index, to detect unphysical states.

Abstract
Prostate cancer is the second most commonly diagnosed cancer in man. Since the first MRI was performed, enormous progress has been made in diagnosis, treatment, and follow up of PCa, mainly due to multiparametric prostatic MRI (mpMRI). Although mpMRI has become the best imaging tool for identifying PCa, some limitations still exist. Prostate imaging with mpMRI is, to date, the best way to locate suspicious lesions to trigger prostate biopsy, plan active surveillance, or definitive treatment. In case of relapse, mpMRI can help detect local disease and provide specific management. It is well known that there is a subset of patients in whom mpMRI fails to depict csPCa. These missed significant cancers demand great attention. Prostate mpMRI quality depends on several factors related to equipment (including equipment vendor, magnet field and gradient strength, coil set used, software and hardware levels, sequence parameter choices), patient (medications, body habitus, motion, metal implants, rectal gas), and most importantly the radiologic interpretation of images (learning curve effects, subjectivity of observations, interobserver variations, and reporting styles). Inter-reader variability represents a huge current limitation of this method. Therefore, mpMRI remains the best imaging tool available to detect PCa, guiding diagnosis, treatment, and follow up while inter-reader variability represents the best limitation. Radiomics can help identifying imaging biomarkers to help radiologist in detecting significant PCa, reducing examination times, and costs.

Abstract
A detailed study of the conformational landscape of chloromethyl-oxirane and chloromethyl-thiirane is here reported. The equilibrium of the three different conformers of the two molecules was assessed, using a joint approach of experimental and theoretical methods. High quality infrared spectroscopy measurements of the liquid and of the crystalline phases were interpreted with the aid of ab initio Molecular Dynamics (AIMD) simulations, anharmonic frequencies and free energy calculations, obtaining a very good reproduction of the experimental data. The modulation of the conformational equilibrium upon the addition of polar and non-polar solvents was computationally evaluated and results found a confirmation in experimental measures.

Abstract
BACKGROUND Atypical small acinar proliferation (ASAP) occurs in approximately 5% of prostate biopsies. Approximately 30%-40% of these patients may develop prostate cancer (PCa) within a 5-year period, often not clinically significant. Current guidelines recommend a repeat biopsy within 3-6 months after the initial diagnosis, but it seem not to be the best strategy. METHODS Objectives-evaluating the natural history of ASAP, stratifying the risk of csPCa after ASAP, identifying predictive factors of PCa after atypical diagnosis. Materials and methods-retrospective single-institutional study on patients undergoing prostate biopsy for suspicious PCa (2005-2016). We evaluated the incidence of overall PCa, intermediate-high risk of PCa and csPCa in case of ASAP, according to D'Amico classification and Epstein modified criteria. RESULTS Out of 4.567 patients undergoing prostate biopsy, ASAP was detected in 2.6% of cases. All patients with ASAP underwent repeat saturation biopsy within 6 months and PCa was diagnosed in 34.5%. According to D'Amico classification, 26%, 5.9%, and 2.5% had low, intermediate, and high-risk disease, respectively. According modified Epstein criteria, the incidence of csPCa was 12.6%. LRT showed that the overall probability to develop PCa doubled when PSA density (PSAD) moved from values lower than 0.13 ng/ml/cc to class 0.13-0.30 ng/ml/cc, and it tripled when PSAD was higher than 0.30 ng/ml/cc. CONCLUSIONS The rate of csPCa in patients with an initial diagnosis of ASAP who had repeat biopsy was 12.6%. The overall PCa rate was 34.5%. Among patient undergoing RP, an upgrading from ncsPCa to csPCa was reported in 35% of cases. PSAD is the only predictive factor directly associated to the risk of developing PCa on repeat biopsy. These findings suggest that immediate repeat biopsy remains the correct strategy in absence of novel predictor factors and non-invasive diagnostic evaluations.

Abstract
In classical molecular dynamics, general purpose atomistic force-fields (FFs) often deliver inaccurate results when dealing with halogen bonds (XBs), notwithstanding their crucial role in many fields of science, ranging from material design to drug development. Given the large dimensions of the systems of interest, it would be therefore desirable to increase the FF accuracy maintaining the simplicity of the standard Lennard-Jones (LJ) plus point charge description to avoid an excessive computational cost. A simple yet effective strategy consists in introducing a number of virtual sites able to mimic the so-called "explicit σ-hole." In this work, we present an automated FF parameterization strategy based on a global optimization of both LJ and charge parameters with respect to accurate quantum mechanical data, purposely computed for the system under investigation. As a test case, we report on two homologue series, characterized either by weak or strong XBs, namely, the di-halogenated methanes and the mono-, di-, and tri-substituted acetonitriles, taking into consideration Cl, Br, and I substituents. The resulting quantum mechanically derived FFs are validated for each compound in the gas and in the condensed phase by comparing them to general purpose and specific FFs without virtual sites and to highly accurate reference quantum mechanical data. The results strongly support the adoption of the specific FFs with virtual sites, which overcome the other investigated models in representing both gas phase energetics and the structural patterns of the liquid phase structure related to the presence of XBs.

Abstract
We present a study by energy-dispersive X-ray diffraction of liquid 2-(2-hydroxyethoxy)ethan-1-ammonium nitrate, NH3CH2CH2(OCH2CH2OH)+NO3- (22HHEAN). This ionic liquid is derived from the parent ethylammonium nitrate (EAN) with an ether link in the chain and a hydroxyl group in the terminal position. The absence of peaks at low-q values in the experimental diffraction curve indicates that the added polar groups and the high conformational isomerism of the cations alter strongly the nanosegregation of the parent EAN liquid. Aggregation between ionic species may involve hydrogen bonding between cations and anions and a variety of intermolecular hydrogen bonds between cations. Diffraction patterns are compared with the results of molecular dynamics simulations with two different force fields: the fixed point charge force field (GAFF) with different charge scaling protocols and the polarizable AMOEBA force field. Most point charge models lead to the appearance of a quite evident low q-peak which decreases gradually, when the percentage and type of the scaling (uniform vs. non-uniform) are increased. In the polarisable model and in the model where only anion charges are scaled to 20%, instead, the pre-peak is absent in agreement with our experiments.

Abstract
BACKGROUND Circulating tumor cells (CTCs) represent a prerequisite for the formation of metastases. The aim of the study was to identify the role of CTCs as a biological marker of aggressiveness of prostate cancer and verify the expression of molecular markers predictive of response to different therapeutic approaches. METHODS Prospective, single-arm, non-randomized trial. Twenty-four patients with prostate cancer were enrolled into two groups: group 1 (N.=11) with localized prostate cancer treated with radical prostatectomy; group 2 (N.=13) with metastatic disease. We performed, dosage of blood PSA and testosterone, detection of EGFR, PSMA, PSA and Androgen Receptor (AR) expression on CTC during pre-treatment and follow-up at 1, 3, 9 and 18 months. RESULTS A total of 65 blood samples were evaluated. In group 1, pre-treatment sampling was negative for the expression of markers on CTC in 90% of the patients while group 2 pre-treatment sampling was positive for the expression of at least one biomarker in seven of 13 patients (54%). After treatment, four patients in group 2 experienced a reduced expression of the markers on CTC, however, in one case there was a new increase of PSA and PSMA at 3 months. One patient had a positivity of AR at 3 months. CONCLUSIONS The expression of PSA, PSMA, EGFR and AR on CTCs appears to be absent in the pre-treatment samplings in cases of localized prostate cancer. The same markers are hyper-expressed before treatment mostly in metastatic prostate cancer and can relate with early biochemical relapse.

Abstract
The ability to locate minima on electronic excited states (ESs) potential energy surfaces both in the case of bright and dark states is crucial for a full understanding of photochemical reactions. This task has become a standard practice for small- to medium-sized organic chromophores thanks to the constant developments in the field of computational photochemistry. However, this remains a very challenging effort when it comes to the optimization of ESs of transition metal complexes (TMCs), not only due to the presence of several electronic ESs close in energy, but also due to the complex nature of the ESs involved. In this article, we present a simple yet powerful method to follow an ES of interest during a structural optimization in the case of TMCs, based on the use of a compact hole-particle representation of the electronic transition, namely the natural transition orbitals (NTOs). State tracking using NTOs is unambiguously accomplished by computing the mono-electronic wave function overlap between consecutive steps of the optimization. Here, we demonstrate that this simple but robust procedure works not only in the case of the cytosine but also in the case of the ES optimization of a ruthenium nitrosyl complex which is very problematic with standard approaches. © 2019 The Authors.

The Π index, previously applied to disclose non-radiative decay channels from the first excited state to the ground state, is very simple in its formulation and can be evaluated, practically with no extra computational cost, and coupled to any quantum method able to provide excited states densities. Indeed, this index relies only on the knowledge of energetics and electron densities of the different electronic states involved in the decay. In the present work, we show the proficiency of the Π index in the general case of decay between excited states by applying it to two model systems well characterized both theoretically and experimentally. In both cases, this descriptor was successful in spotting the regions where excited states are more likely to decay, thus suggesting its potential interest for further application in the design of new compounds. © 2018 Wiley Periodicals, Inc.

Abstract
In this article, we report the study of structural and dynamical properties for a series of acetonitrile/propylammonium nitrate mixtures as a function of their composition. These systems display an unusual increase in intensity in their X-ray diffraction patterns in the low-q regime, and their 1H-NMR diffusion-ordered NMR spectroscopy (DOSY) spectra display unusual diffusivities. However, the magnitude of both phenomena for mixtures of propylammonium nitrate is smaller than those observed for ethylammonium nitrate mixtures with the same cosolvent, suggesting that the cation alkyl tail plays an important role in these observations. The experimental X-ray scattering data are compared with the results of molecular dynamics simulations, including both ab initio studies used to interpret short-range interactions and classical simulations to describe longer range interactions. The higher level calculations highlight the presence of a strong hydrogen bond network within the ionic liquid, only slightly perturbed even at high acetonitrile concentration. These strong interactions lead to the symmetry breaking of the NO3- vibrations, with a splitting of about 88 cm-1 in the ν3 antisymmetric stretch. The classical force field simulations use a greater number of ion pairs, but are not capable of fully describing the longest range interactions, although they do successfully account for the observed concentration trend, and the analysis of the models confirms the nano-inhomogeneity of these kinds of samples.

Abstract
The spectroscopic properties of light-harvesting (LH) antennae in photosyntehtic organisms represent a fingerprint that is unique for each specific pigment-protein complex. Because of that, spectroscopic observations are generally combined with structural data from X-ray crystallography to obtain an indirect representation of the excitonic properties of the system. Here, an alternative strategy is presented which goes beyond this empirical approach and introduces an ab initio computational description of both structural and electronic properties and their dependence on the temperature. The strategy is applied to the peripheral light-harvesting antenna complex (LH2) present in purple bacteria. By comparing this model with the one based on the crystal structure, a detailed, molecular level explanation of the absorption and circular dichroism (CD) spectra and their temperature dependence is achieved. The agreement obtained with the experiments at both low and room temperature lays the groundwork for an atomistic understanding of the excitation dynamics in the LH2 system.

Abstract
We address the issue of identifying the mediators of effective interactions in cuprates superconductors. Specifically, we use inversion theory to analyze Raman spectra of optimally and over-doped La2-x Sr x CuO4 samples. This allows us to extract the so-called glue function without making any a priori assumption based on any specific model. We use instead two different techniques, namely the singular value decomposition and a multi-rectangle decomposition. With both techniques we find consistent results showing that: (i) two distinct excitations are responsible for the glue function, which have completely different doping dependence. One excitation becomes weak above optimal doping, where on the contrary the other keeps (or even slightly increases) its strength; (ii) there is a marked temperature dependence on the weight and spectral distribution of these excitations, which therefore must have a somewhat critical character. It is quite natural to identify and characterize these two distinct excitations as damped antiferromagnetic spin waves and damped charge density waves, respectively. This sets the stage for a scenario in which superconductivity is concomitant and competing with a charge ordering instability.
