Anxiety, depression, urinary continence, and sexuality in patients undergoing radical prostatectomy: preliminary findings.

Objectives: Evaluate the relationship between psychological distress, namely anxiety and depression, with urinary continence and recovery of erectile function in patients undergoing radical prostatectomy (RP).

Methods: We retrospectively analyzed data from 33 consecutive patients who underwent RP in a single tertiary-referral academy between 01/2018 to 01/2019. We used the International Index of Erectile Function (IIEF-15), the Sexual Complaints Screener for Men (SCS-M), and the Hospital Anxiety and Depression Scale (HADS), validated questionnaires for the assessment of sexual function, anxiety, and depression experiences, respectively.

Italian Versions of the 12-Item Sexual Distress Scale (SDS) and the 5-Item Sexual Distress Scale-Short Form (SDS-SF): Psychometric Properties.

The study aimed to analyze the psychometric properties of the Italian versions of the 12-item Sexual Distress Scale (SDS) and the 5-item Sexual Distress Scale-Short Form (SDS-SF). A total sample of 2291 adults (1361 women, 930 men) participated through a web survey completing the SDS, the FSFI, the IIEF, the PANAS and the SCL-90-R. The results supported the adequacy of both the SDS and SDS-SF factor structures, good reliability (respectively, α = .

Which psychosocial variables affect drive the most? Analysis of sexual desire in a group of Italian men.

Literature lacks wide studies on variables affecting sexual desire in men. Aim of this study was to explore the role of some psychosocial variables such as quality of life, sexual function, distress, sexual satisfaction, psychological symptoms, emotions, alexithymia, couple adjustment, sexism, dysfunctional beliefs, cognitive schemas, and modes. A self-administered survey reached 450 heterosexual Italian men (age 31.

Polariton-mediated energy transfer between organic dyes in a strongly coupled optical microcavity.

Strongly coupled optical microcavities containing different exciton states permit the creation of hybrid-polariton modes that can be described in terms of a linear admixture of cavity-photon and the constituent excitons. Such hybrid states have been predicted to have optical properties that are different from their constituent parts, making them a test bed for the exploration of light-matter coupling. Here, we use strong coupling in an optical microcavity to mix the electronic transitions of two J-aggregated molecular dyes and use both non-resonant photoluminescence emission and photoluminescence excitation spectroscopy to show that hybrid-polariton states act as an efficient and ultrafast energy-transfer pathway between the two exciton states.

Time reversal symmetric topological exciton condensate in bilayer HgTe quantum wells.

We investigate a bilayer system of critical HgTe quantum wells, each featuring a spin-degenerate pair of massless Dirac fermions. In the presence of an electrostatic interlayer Coulomb coupling, we determine the exciton condensate order parameter of the system self-consistently. Calculating the bulk topological Z2 invariant of the resulting mean-field Hamiltonian, we discover a novel time reversal symmetric topological exciton condensate state, coined the helical topological exciton condensate.

Plasmons due to the interplay of Dirac and Schrödinger fermions.

We study the interplay between Dirac and Schrödinger fermions in the polarization properties of a two-dimensional electron gas (2DEG). Specifically, we analyze the low-energy sector of narrow-gap semiconductors described by a two-band Kane model. In the context of quantum spin Hall insulators, particularly, in Hg(Cd)Te quantum wells, this model is named the Bernevig-Hughes-Zhang model.

Delayed ejaculation and alexithymia: what is the relationship?

Delayed Ejaculation (DE) is probably the least studied and understood of the male sexual dysfunctions (MSD). There is still little unanimity concerning its psychological/interpersonal aetiology. Previous studies found that MSD are strongly related with alexithymia, a multifaceted personality construct that describes a disturbance in the regulation of emotions.

A randomized, placebo-controlled, preoperative trial of allopurinol in subjects with colorectal adenoma.

Inflammation and oxidative stress play a crucial role in the development of colorectal cancer (CRC) and interference with these mechanisms represents a strategy in CRC chemoprevention. Allopurinol, a safe molecular scavenger largely used as antigout agent, has been shown to increase survival of patients with advanced CRC and to reduce CRC incidence in long-term gout users in epidemiologic studies. We conducted a randomized, double-blind, placebo-controlled preoperative trial in subjects with colorectal adenomatous polyps to assess the activity of allopurinol on biomarkers of colorectal carcinogenesis.

Cyclosporine as monotherapy for psoriasis in the setting of chronic HCV infection: a forgotten therapeutical option.

Background: Treatment of psoriasis in the setting of chronic hepatitis C virus (HCV) infection is difficult, because standard therapies like methotrexate are associated with increased hepatic toxicity. Due to the HCV suppressive effect. Cyclosporine may represent a valid systemic alternative for psoriatic-HCV patients.

Electric field control of spin rotation in bilayer graphene.

The manipulation of the electron spin degree of freedom is at the core of the spintronics paradigm, which offers the perspective of reduced power consumption, enabled by the decoupling of information processing from net charge transfer. Spintronics also offers the possibility of devising hybrid devices able to perform logic, communication, and storage operations. Graphene, with its potentially long spin-coherence length, is a promising material for spin-encoded information transport.

Predicting mortality in non-variceal upper gastrointestinal bleeders: validation of the Italian PNED Score and Prospective Comparison with the Rockall Score.

Objectives: We sought (i) to validate a new prediction rule of mortality (Progetto Nazionale Emorragia Digestiva (PNED) score) on an independent population with non-variceal upper gastrointestinal bleeding (UGIB) and (ii) to compare the accuracy of the Italian PNED score vs. the Rockall score in predicting the risk of death.

Methods: We conducted prospective validation of analysis of consecutive patients with UGIB at 21 hospitals from 2007 to 2008.

Predictive factors of mortality from nonvariceal upper gastrointestinal hemorrhage: a multicenter study.

Objectives: From an Italian Registry of patients with upper gastrointestinal hemorrhage (UGIH), we assessed the clinical outcomes and explored the roles of clinical, endoscopic, and therapeutic factors on 30-day mortality in a real life setting.

Methods: Prospective analysis of consecutive patients endoscoped for UGIH at 23 community and tertiary care institutions from 2003 to 2004. Covariates and outcomes were defined a priori and 30-day follow-up obtained.

Cerebral vasomotor reactivity is reduced in patients with erectile dysfunction.

Background: Erectile dysfunction (ED) is not only evidence of diffuse atherosclerosis but also an index of early endothelial damage. We investigated cerebrovascular reactivity, expression of early arterial damage, in patients with isolated ED (ED+) and controls (ED-).

Materials And Methods: Fifteen ED+ and 15 ED- subjects, matched for age (ED+: 58+/-6, ED-: 59 +/- 4 years) and vascular risk factors, were submitted to carotid duplex ultrasound and transcranial Doppler.

Dysregulation of emotions and premature ejaculation (PE): alexithymia in 100 outpatients.

Introduction: There is still a lack of agreement on etiology, definition, and mechanisms that underlie premature ejaculation (PE) as well as on the different role and interaction between psychological and biological factors. Alexithymia is a deficit in identifying and communicating emotions that is presumed to play an important role in psychosomatic diseases. The influences of alexithymic features on sexuality are still understudied.
