Intraoperative Fluorescent Ureter Visualization for Transvaginal High Uterosacral Ligament Suspension for Severe Pelvic Organ Prolapse.

INTRODUCTION AND HYPOTHESIS: We aimed to demonstrate the feasibility of ureteral navigation using intra-ureteric indocyanine green (ICG) and near-infrared fluorescence (NIRF) imaging during transvaginal high uterosacral ligament suspension for prolapse repair to reduce the risk of iatrogenic ureteral injury. METHODS: A cystoscope was inserted into the bladder, the tip of a 6-F open-end ureteral catheter was inserted into the ureteral orifices, and ICG was instilled into the ureters. The ureteral path was then clearly identified using NIRF imaging. Sutures were safely placed in the uterosacral ligaments at the level of the ischial spine, taking advantage of direct ureteral visualization. RESULTS: At the end of the procedure, diagnostic cystoscopy was performed to confirm ureteral patency. No intraoperative or postoperative complications were observed. CONCLUSIONS: Intra-ureteric ICG-NIRF imaging represents a simple, inexpensive, and reproducible trick for intraoperative ureteral detection, and could reassure surgeons during difficult operations, for instance, in the case of severe prolapse and/or when ureteral course abnormalities are expected.

Impact of Mannitol Bladder Distension in the Intraoperative Detection of Ureteral Kinking During Pelvic Floor Surgery.

INTRODUCTION AND HYPOTHESIS: Ureteral injuries are the most feared complications of gynecological surgery and therefore intraoperative recognition is of the utmost importance. Intraoperative cystoscopy represents the diagnostics of choice to investigate ureteral patency thanks to the direct visualization of ureteral flows after administration of infusion mediums. In this study, we aimed to compare the diagnostic performance of saline versus mannitol intraoperative cystoscopy in terms of false negatives in a large cohort of patients. METHODS: We retrospectively analyzed data of patients who underwent vaginal hysterectomy and high uterosacral ligament suspension for POP. Patients were divided in two groups based on the use of saline or mannitol medium for intraoperative cystoscopy. Postoperative daily control of serum creatinine was performed until discharge, as well as urinary tract imaging, in symptomatic patients. RESULTS: A total of 925 patients underwent vaginal hysterectomy followed by high USL suspension for POP. Saline and mannitol medium were used in 545 patients and 380 patients respectively. Postoperative ureteral injuries were identified in 12 patients, specifically in 2% of the saline group and in 0.3% of the mannitol group. CONCLUSIONS: The use of mannitol instead of saline as a bladder distension medium was able to significantly reduce the occurrence of postoperative ureteral sequelae.

High Uterosacral Ligaments Suspension for Post-Hysterectomy Vaginal Vault Prolapse Repair.

Background and Objectives: Uterosacral ligaments (USLs) suspension is a well-studied, safe, and long-lasting technique for central compartment correction. Preliminary clinical experiences showed encouraging data for this technique, also for post-hysterectomy vaginal vault prolapse surgical treatment. However, up-to-date evidence for post-hysterectomy vaginal vault prolapse repair through high uterosacral ligaments suspension is limited. Consequently, with this study, we aimed to assess the efficiency, complications frequency, and functional results of native-tissue repair through USLs in vaginal vault prolapse. Materials and Methods: This was a retrospective study. Women with symptomatic vaginal vault prolapse (≥stage 2) who underwent surgery with transvaginal native-tissue repair by high uterosacral ligaments were included. Patient characteristics, preoperative assessment, operative data, postoperative follow-up visits, and re-interventions were collected from the hospital's record files. High uterosacral ligament suspension was performed according to the technique previously described by Shull. A transverse apical colpotomy at the level of the post-hysterectomy scar was performed in order to enter the peritoneal cavity. USLs were identified and transfixed from ventral to dorsal with three absorbable sutures. Sutures were then passed through the vaginal apex and tightened to close the transverse colpotomy and suspend the vaginal cuff. At the end of the surgical time, a diagnostic cystoscopy was performed in order to evaluate ureteral bilateral patency. Using the POP-Q classification system, we considered an objective recurrence as the descensus of at least one compartment ≥ II stage, or the need for a subsequent surgery for POP. The complaint of bulging symptoms was considered the item to define a subjective recurrence. We employed PGI-I scores to assess patients' satisfaction. Results: Forty-seven consecutive patients corresponding to the given period were analyzed. No intraoperative complications were observed. We observed one postoperative hematoma that required surgical evacuation. Thirty-three patients completed a minimum of one-year follow-up (mean follow-up 21.7 ± 14.6 months). Objective cure rate was observed in 25 patients (75.8%). No patients required reintervention. The most frequent site of recurrence was the anterior compartment (21.2%), while apical compartment prolapse relapsed only in 6% of patients. An improvement in all POP-Q parameters was recorded except TVL which resulted in a mean 0.5 cm shorter. Subjective recurrence was referred by 4 (12.1%) patients. The mean satisfaction assessed by PGI-I score was 1.6 ± 0.8. Conclusion: This analysis demonstrated that native-tissue repair through high USL suspension is an effective and safe procedure for the treatment of post-hysterectomy vaginal vault prolapse. Objective, subjective, functional, and quality of life outcomes were satisfactory, with minimal complications.

A Novel Method for the Measurement of the Vaginal Wall Thickness by Transvaginal Ultrasound: A Study of Inter- and Intra-Observer Reliability.

Background and Objectives: A consensus regarding the optimal sonographic technique for measuring vaginal wall thickness (VWT) is still absent in the literature. This study aims to validate a new method for measuring VWT using a biplanar transvaginal ultrasound probe and assess both its intra-operator and inter-operator reproducibility. Material and Methods: This prospective study included patients with genitourinary syndrome of menopause-related symptoms. Women were scanned using a BK Medical Flex Focus 400 with the 65 × 5.5 mm linear longitudinal transducer of an endovaginal biplanar probe (BK Medical probe 8848, BK Ultrasound, Peabody, MA, USA). Vaginal wall thickness (VWT) measurements were acquired from the anterior and posterior vaginal wall at three levels. Results: An inter-observer analysis revealed good consistency between operators at every anatomical site, and the intra-class coefficient ranged from 0.931 to 0.987, indicating high reliability. An intra-observer analysis demonstrated robust consistency in vaginal wall thickness measurements, with an intra-class coefficient exceeding 0.9 for all anatomical sites. Conclusions: The measurement of vaginal wall thickness performed by transvaginal biplanar ultrasound was easy and demonstrated good intra- and inter-operator reliability.

Changes in Pelvic Floor Ultrasonographic Features after Flat Magnetic Stimulation in Women with Chronic Pelvic Pain and Levator Ani Muscle Hypertonicity.

Background and Objectives: Chronic pelvic pain (CPP) represents a major public health problem for women with a significant impact on their quality of life. In many cases of CPP, due to gynecological causes-such as endometriosis and vulvodynia-improper pelvic floor muscle relaxation can be identified. Treatment of CPP with pelvic floor hypertonicity (PFH) usually involves a multimodal approach. Traditional magnetic stimulation has been proposed as medical technology to manage muscle hypertonicity and pelvic pain conditions through nerve stimulation, neuromodulation, and muscle relaxation. New Flat Magnetic Stimulation (FMS)-which involves homogeneous rather than curved electromagnetic fields-has the potential to induce sacral S2-S4 roots neuromodulation, muscle decontraction, and blood circulation improvement. However, the benefits of this new technology on chronic pelvic pain symptoms and biometrical muscular parameters are poorly known. In this study, we want to evaluate the modification of the sonographic aspect of the levator ani muscle before and after treatment with Flat Magnetic Stimulation in women with chronic pelvic pain and levator ani hypertonicity, along with symptoms evolution. Materials and Methods: A prospective observational study was carried out in a tertiary-level Urogynaecology department and included women with CPP and PFH. Approval from the local Ethics Committee was obtained before the start of the study (protocol code: MAGCHAIR). At the baseline, the intensity of pelvic pain was measured using a 10 cm visual analog scale (VAS), and patients were asked to evaluate their pelvic floor symptoms severity by answering the question, "How much do your pelvic floor symptoms bother you?" on a 5-answer Likert scale. Transperineal ultrasound (TPU) was performed to assess anorectal angle (ARA) and levator ani muscle minimal plane distance (LAMD). Treatment involved Flat Magnetic Stimulation alone or with concomitant local or systemic pharmacological therapy, depending on the patient's preferences. FMS was delivered with the DR ARNOLD system (DEKA M.E.L.A. Calenzano, Italy). After the treatment, patients were asked again to score the intensity of pelvic pain using the 10 cm visual analog scale (VAS) and to evaluate the severity of their pelvic floor symptoms on the 5-answer Likert scale. Patients underwent TPU to assess anorectal angle (ARA) and levator ani muscle minimal plane distance (LAMD). Results: In total, 11 patients completed baseline evaluation, treatment, and postoperative evaluation in the period of interest. All patients underwent eight sessions of Flat Magnetic Stimulation according to the protocol. Adjuvant pharmacological treatment was used in five (45.5%) patients. Specifically, we observed a significant increase in both ARA and LAMD comparing baseline and post-treatment measurements (p < 0.001). Quality of life scale scores at baseline and after treatment demonstrated a significant improvement in both tools (p < 0.0001). Conclusions: Flat Magnetic Stimulation, with or without adjuvant pharmacological treatment, demonstrated safety and efficacy in reducing pelvic floor hypertonicity, resulting in improvement in symptoms' severity and sonographic parameters of muscular spasm.

Planarian cell number depends on blitzschnell, a novel gene family that balances cell proliferation and cell death.

Control of cell number is crucial to define body size during animal development and to restrict tumoral transformation. The cell number is determined by the balance between cell proliferation and cell death. Although many genes are known to regulate those processes, the molecular mechanisms underlying the relationship between cell number and body size remain poorly understood. This relationship can be better understood by studying planarians, flatworms that continuously change their body size according to nutrient availability. We identified a novel gene family, blitzschnell (bls), that consists of de novo and taxonomically restricted genes that control cell proliferation:cell death ratio. Their silencing promotes faster regeneration and increases cell number during homeostasis. Importantly, this increase in cell number leads to an increase in body size only in a nutrient-rich environment; in starved planarians, silencing results in a decrease in cell size and cell accumulation that ultimately produces overgrowths. bls expression is downregulated after feeding and is related to activity of the insulin/Akt/mTOR network, suggesting that the bls family evolved in planarians as an additional mechanism for restricting cell number in nutrient-fluctuating environments.

HIV and STI Prevention Among Spanish Women Who have Sex with Women: Factors Associated with Dental Dam and Condom Use.

The scientific community has systematically ignored the needs of women who have sex with women (WSW). The invisibilization of romantic and sexual relationships between women has caused a profound lack of knowledge about the impact of HIV and other STIs on this population subgroup. This study aims to analyze the frequency of dental dam and condom use in WSW and identify the variables that explain the use of these two preventive methods. The sample is composed of 327 women aged between 18 and 60 years (M = 27.82; SD = 8.10). The results indicate that only 4.7% of those who practice cunnilingus and 5.2% of those who practice anilingus report "always" using dental dam (systematic use). Condoms are used systematically by 37.1% of those who practice vaginal penetration and 37.8% of those who practice anal penetration. Age, high perceived self-efficacy, and adequate assertive communication skills are variables significantly related to preventive behavior. The severity attributed to HIV and the perceived risk of infection are protective factors regarding dental dam use. For condom use, high levels of internalized homophobia and drug use are risk factors. Future preventive strategies should provide information on preventive strategies to WSW who, for different reasons, are not involved in LGBT contexts or associations and, therefore, do not have access to training activities and mistakenly believe that they are invulnerable as they do not have sexual relations with men.

Total introital obliteration as a consequence of lichen sclerosus: a rare cause of urinary retention.

INTRODUCTION AND HYPOTHESIS: Lichen sclerosus is a chronic inflammatory dermatitis, with a predilection for the anogenital area. In later stages, lichen sclerosus may develop into widespread scarring, and occasionally leading to severe introital stenosis and urinary retention. Our video is aimed at presenting a case of surgical management of lichen sclerosus-related introital stenosis determining urinary retention. METHODS: An 82-year-old woman was evaluated for almost complete urinary retention, with concomitant continuous enuretic urinary leakage all day and night and recurrent urinary tract infection symptoms. The gynecological evaluation demonstrated a complete introital obliteration, without obvious communications for urine passing. After proper informed consent, the patient was admitted for vulvo-perineoplasty. RESULTS: The featured procedure was completed in 25 min and blood loss was negligible. No surgical complications were observed. On postoperative day 1, the patient was successfully discharged home with topical steroid treatment. Histological examination confirmed typical features of lichen sclerosus pathology. At follow-up visits the patient was asymptomatic and examination confirmed persistence of introital patency. CONCLUSIONS: The featured video shows a vulvo-perineoplasty performed in a patient with lichen sclerosus-related complete introital obliteration and urinary retention. The procedure was successful in obtaining anatomical repair and relieving urinary symptoms.

Surgical management of rectovaginal fistula after stapled transanal rectal resection for prolapsed hemorrhoids.

INTRODUCTION AND HYPOTHESIS: Rectovaginal fistula is an epithelium-lined direct communication route between the vagina and the rectum. The gold standard of fistula management is surgical treatment. Rectovaginal fistula after stapled transanal rectal resection (STARR) may be challenging to treat, due to the extensive scarring, the local ischemia, and the risk of rectal stenosis. We aimed to present a case of iatrogenic rectovaginal fistula after STARR that was successfully treated with a transvaginal primary layered repair and bowel diversion. METHODS: A 38-year-old woman was referred to our division for continuous fecal discharge through her vagina that developed a few days after she had a STARR for prolapsed hemorrhoids. Clinical examination revealed a 2.5 cm-wide direct communication between the vagina and rectum. After proper counseling, the patient was admitted to transvaginal layered repair and temporary laparoscopic bowel diversion RESULTS: No surgical complications were observed. The patient was successfully discharged home on postoperative day 3. Bowel diversion was reversed after 2 months. At the current follow-up (6 months), the patient is asymptomatic and without recurrence. CONCLUSIONS: The procedure was successful in obtaining anatomical repair and relieving symptoms. This approach represents a valid procedure for the surgical management of this severe condition.

Pelvic pain after laparoscopic lateral suspension for pelvic organ prolapse: an unrecognized problem?

INTRODUCTION AND HYPOTHESIS: The laparoscopic lateral suspension (LLS) represents an alternative mesh procedure to avoid the dissection at the promontory. However, mesh-related complications such as chronic pelvic pain, dyspareunia, and bladder pain are emerging. The present study is aimed to present a video case report and describe a small case series of patients referred to our center for chronic pelvic pain after LLS. METHODS: A surgical video of the management of a 50-year-old woman with chronic abdominal and pelvic pain, dyspareunia, and recurrent urinary tract infection (UTIs) after uterus sparing LLS is provided. Moreover, we performed a retrospective chart review of similar cases in our institution. RESULTS: The featured procedure was completed without complications and was successful in obtaining symptom relief. Between 2018 and 2022 five patients underwent total or subtotal mesh removal for pain-related symptoms after LLS. At the median follow-up of 24 months, all patients were free from pain, but two (40%) required reoperation for prolapse recurrence CONCLUSIONS: Our experience suggests that LLS involves a certain risk of chronic pelvic pain, which may be challenging to manage and require surgical treatment.

Prevalence and severity of lower urinary tract symptoms in the third trimester of pregnancy.

INTRODUCTION AND HYPOTHESIS: Pregnancy is a risk factor for urinary disorders, mainly in the third trimester. Lower urinary tract symptoms (LUTS) are often underreported by health care professionals and significantly impact the quality of life of pregnant women. Our objective is to analyse lower urinary tract function during the third trimester of pregnancy and assess the impact of traditional risk factors for pelvic floor dysfunctions on bladder health in pregnant women. METHODS: This is a secondary analysis of a multicentre cross-sectional study. Third-trimester pregnant women aged 18 years or older anonymously filled in the "Italian Pelvic Floor Questionnaire for pregnant and postpartum women" questionnaire, validated for pelvic floor disorders in pregnancy and postpartum. RESULTS: A total of 927 pregnant patients completed the questionnaire. Among them, 97.3% complained of at least one urinary disorder. Frequency was the symptom reported most often (77.3%), whereas nocturnal enuresis was the least reported (17%). Despite the high prevalence of LUTS in our sample, only 13.4% reported that they negatively impact their quality of life. Overweight and obesity, advanced maternal age, smoking, family history of pelvic floor disorders and poor pelvic floor contraction capacity were confirmed to be risk factors for the onset of LUTS, even in our population. CONCLUSIONS: Urinary symptoms are extremely common in the third trimester and significantly affect the quality of life of pregnant women. Since overweight, obesity, smoking and reduced pelvic floor contractility emerged as modifiable risk factors for the development of these symptoms, prevention and adequate counselling are cornerstones of pregnancy care.

Italian validation of the Pelvic Floor Distress Inventory (PFDI-20) questionnaire.

INTRODUCTION AND HYPOTHESIS: The use of validated Quality of Life (QoL) questionnaires is useful in the standardization and interpretation process of pelvic floor patient symptoms, due to their functional nature and high prevalence. The Pelvic Floor Distress Inventory QoL questionnaire (PFDI-20) serves both as a symptom inventory and a measure of the degree of bother and distress caused by pelvic floor symptoms. It includes items related to pelvic organ prolapse and lower gastrointestinal and bladder dysfunction. METHODS: After consensus translation and a comprehension test, the Italian version of the questionnaire was submitted to patients reporting bowel, bladder, or pelvic disorders (cases) and to asymptomatic women (controls). Cases received the questionnaire once again 2 weeks later by email. RESULTS: A total of 254 patients answered the questionnaire. Construct validity was demonstrated by discriminating between cases and controls. Convergent validity was demonstrated for each domain (F < 0.001). In-ernal consistency reliability showed a satisfactory range (0.816-0.860). CONCLUSIONS: The PFDI-20 allows a comprehensive assessment of the effect of pelvic floor disorders on the quality of life of women. Moreover, the PFDI-20 represents a very solid QoL tool, since it has been extensively used in literature, and its use is highly recommended by the International Consultation on Incontinence. The present study demonstrated good features for the Italian version of the PFDI-20 questionnaire.

Atypical Sexual Interests in Compulsive Sexual Behavior: Results From a Phallometric Study.

The link between Compulsive Sexual Behavior (CSB) and atypical sexual interests is elusive. This study aimed to provide preliminary insights into the relationship between both aspects. The study sample comprised 61 self-identified straight men. CSB was measured through a composite self-report index assessing symptoms of CSB, whereas sexual interests -atypical and normophilic- were assessed objectively through penile plethysmography. The CSB index had small, non-significant correlation with greater sexual response to different sexual stimuli (rgeneral sexual responsiveness=.127 [95% CI: -.137, .384]). In terms of overall sexual interest, increased scores on the CSB index had small, non-significant correlation with a higher preference for younger sexual stimuli (r = -.098 [95% CI: -.499, .215]) and persuasive sex (r = .10 [95% CI: -.168, .316]). Finally, CSB had a moderate correlation with sexual response when presented with stimuli depicting "female toddler coercive" (r = .27 [95% CI: -.083, .544]). We conclude that our findings do not support the hypotheses that CSB is significantly related to an increased arousability across sexual stimuli. The study findings also suggest that CSB may be, to a small degree, predisposed to experience sexual attraction toward children. Given the preliminary nature of the study, these conclusions warrant further research. Alternative explanations for the study findings related to the particular components of CSB that may be related to typical and atypical sexual interests are also considered.

Flat Magnetic Stimulation for Urge Urinary Incontinence.

Background and Objectives: Strategies for overactive bladder syndrome (OAB) management involve, among others, strengthening the bladder outlet to suppress urgency and neuromodulating the sacral roots. Magnetic stimulation (MS) is a technology that involves an extracorporeal device that is able to provide an electromagnetic field specifically designed to interact with pelvic floor neuromuscular tissue. The resulting tissue electrical activity induces contraction of the pelvic muscle and neuromodulation of the S2-S4 sacral roots. Flat Magnetic Stimulation (FMS) is a relevant advancement involving homogeneous electromagnetic fields, which are able to optimize the effect on the entire pelvic area. However, the benefits of this new technology for OAB syndrome are poorly known. Consequently, the aim of our study is to analyze the outcomes and quality of life (QoL) impact of FMS with Dr. Arnold (DEKA, Calenzano, Italy) in women suffering from OAB syndrome associated with urinary incontinence. Materials and Methods: This prospective study included patients with OAB, urge urinary incontinence, and no ongoing OAB treatments. At baseline (T0), the Incontinence Impact Questionnaire (IIQ-7), the Female Sexual Function Index (FSFI-19), and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) were collected. Patients underwent 8 FMS sessions of 25 min each in one month. At the termination of the therapy (T1), women repeated the ICIQ-UI SF, FSFI-19, and IIQ-7 tools. Moreover, the Patient Global Impression of Improvement (PGI-I) questionnaire was collected to evaluate the cure rate. Results: Our study enrolled a total of 57 consecutive patients. Most women had at least one second- or third-line treatment before FMS, while the remaining naive patients had contraindications to pharmacological treatments. No women reported adverse effects during the treatment. After the treatment, we observed a decrease in the IIQ-7 (p < 0.001) and ICIQ-UI SF scores (p < 0.001) and an improvement in sexual function (p < 0.001) evaluated with FSFI-19. According to PGI-I scores, 42 (73.7%) women referred to some kind of improvement, scoring ≤ 3 points. Specifically, 8.7% of patients considered themselves very much improved, 29.8% much improved, 35.1% minimally improved, and 26.3% found no changes. FMS was effective in treating OAB symptoms without any adverse effects. The mechanism is supposed to be related to suppressing the initiation of micturition. This makes FMS a promising device for treating naive and refractory urge urinary incontinence. Conclusions: The new FMS represents a promising non-pharmacological option for the treatment of naive and refractory OAB.

Sexual life of Spanish women during the lockdown by COVID-19: Differences according to sexual orientation?

The COVID-19 pandemic may have exacerbated the sexual health differences that already existed among women based on their sexual orientation. Therefore, a total of 971 Spanish women aged 18-60 years (84 % heterosexual and 16 % with a minority sexual orientation) answered an ad hoc online questionnaire about sexual behavior during April 2020. Compared to heterosexual women, sexual minority women showed a greater increase in sexual frequency, masturbated more, had more sex with a housemate, and engaged in more online sexual activities during lockdown. The emotional impact of the pandemic, having privacy, and age showed a relationship with the quality of sexual life, but not sexual orientation. Based on these results, women's sexual lives are not as closely related to their sexual orientation as they are to other variables. Therefore, it seems more necessary to address issues affecting women in general during lockdown than to focus on their specific sexual orientation.

What Does Heterosexuality Mean? Same-Sex Attraction, Behaviors, and Discomfort Among Self-identified Heterosexual Young Adults from Spain.

Sexuality has been censored by Spanish culture, where legal progress in the form of new policies about sexual diversity rights has not been followed by lower levels of social discrimination. This has affected sexual development across the lifespan for both sexual minorities and heterosexual people who experience their sexuality outside of heteronormativity. However, the literature has regularly excluded the possible consequences of the experience of sexuality within prescriptive categories, particularly in heterosexual people. This study delves deeper into the same-sex experiences of heterosexual women and men and the discomfort they may feel toward such experiences in Spain. A total of 2900 young Spanish people who self-identified as heterosexual completed a questionnaire on sexual diversity and experiences related to sexual orientation. The mean age was 24.22 years (SD = 5.71), 71.1% were women, and 28.9% were men. More heterosexual women than heterosexual men reported having had same-sex attraction, fantasies, desires, and behavioral intentions. However, these men and women reported having similar levels of same-sex sexual intercourse. The discomfort level experienced was higher among heterosexual men and younger people, suggesting the possibility that traditional norms restrict behavioral expression of sexuality among these individuals. At least in the Spanish context, these gender differences should be taken into account to adjust all psychological and educational interventions in the future to improve inclusive sexual attitudes and the treatment of discomfort with sexual orientation. Following these results, research on sexual diversity should focus on young heterosexual people who have different same-sex experiences according to gender differences.

Search of antimicrobial lactic acid bacteria from Salmonella-negative dogs.

BACKGROUND: Salmonellosis is one of the most important food-borne zoonotic disease affecting both animals and humans. The objective of the present study was to identify gastrointestinal (GI) lactic acid bacteria (LAB) of canine-origin from Salmonella-negative dogs' faeces able to inhibit monophasic Salmonella Typhimurium previously isolated from dogs' faeces, in order to be used as a potential probiotic in pet nutrition. RESULTS: Accordingly, 37 LAB were isolated from Salmonella-negative dogs' faeces and tested against monophasic S. Typhimurium using the spot on lawn method out of which 7 strains showed an inhibition halo higher than 2.5 cm. These 7 strains were also tested with the co-culture method and one showed the greatest inhibition value (p < 0.05). Subsequently, the isolate was identified through 16S rRNA sequencing and sequence homology and designated as Ligilactobacillus salivarius (L. salivarius). LAB from Salmonella-positive dogs were also identified and none was the selected strain. Finally, to identify the mechanism of inhibition of L. salivarius, the supernatant was analyzed, and a dose response effect was observed. CONCLUSIONS: It is concluded that the canine-origin L. salivarius, could possess some in vitro functional attributes of a candidate probiotic and could prevent monophasic S. Typhimurium colonization or inhibit its activity if the infection occurs.

Italian validation of the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12).

INTRODUCTION AND HYPOTHESIS: The aim of this study was to translate the English short form of Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and evaluate its validity, internal consistency, and test-retest reliability. METHODS: The questionnaire was translated into Italian by standardized procedural steps, and the final version was submitted to women referred to urogynecological outpatient care for genital prolapse or urinary incontinence reporting sexual disorders (cases) or not (controls). For the test-retest evaluation, cases received the questionnaire 2 weeks later. The Wilcoxon test (non-parametric) was used to assess differences between cases and controls. Convergent validity was tested with the Italian version of the FSFI-19. The internal consistency was tested using Cronbach's alpha. The degree of concordance/agreement was measured with Cohen's kappa. The absolute agreement of test-retest results was tested with the intraclass correlation coefficient (ICC). RESULTS: Sixty women were recruited for the study and answered the questionnaire. The overall rate of missing items was 1.3%. Construct validity was demonstrated, as the questionnaire discriminated significantly between patients with and without symptoms. Convergent validity with FSFI-19 was tested, and a linear correlation between scores was demonstrated (F < 0.001). Internal consistency reliability evaluated with Cronbach's alpha was satisfactory (0.54-0.81). Cohen's kappa values as absolute agreement coefficients were between 0.59 and 0.80 (good agreement). Intraclass correlation coefficients ranged between 0.88 and 0.94 (very satisfactory agreement) for each functional domain. CONCLUSIONS: The Italian version of the PISQ-12 is reliable, valid, and consistent.

Detrusor underactivity prevalence and risk factors according to different definitions in women attending urogynecology clinic.

INTRODUCTION AND HYPOTHESIS: There is still no consensus on definitions of detrusor underactivity; therefore, it is difficult to estimate the prevalence. The primary objective of the study was to evaluate the prevalence of detrusor underactivity in a cohort of patients with pelvic floor disorders according to different proposed urodynamics definitions. The secondary objectives were to estimate the association between detrusor underactivity and symptoms, anatomy and urodynamic findings and to build predictive models. METHODS: Patients who performed urodynamic evaluation for pelvic floor disorders between 2008 and 2016 were retrospectively analyzed. Detrusor underactivity was evaluated according to Schafer's detrusor factor, Abrams' bladder contractility index and Jeong cut-offs. The degree of concordance between each method was measured with Cohen's kappa, and differences were tested using Student's t test, Wilcoxon test and Pearson's chi-squared test. RESULTS: The prevalence of detrusor underactivity among a cohort of 2092 women, concerning the three urodynamic definitions, was 33.7%, 37.0% and 4.1%, respectively. Age, menopausal status, voiding/bulging symptoms, anterior and central prolapse, first desire to void and positive postvoid residual were directly related to detrusor underactivity. Conversely, stress urinary incontinence, detrusor pressures during voiding and maximum flow were inversely associated. Final models for detrusor underactivity resulted in poor accuracy for all considered definitions. CONCLUSIONS: The prevalence of detrusor underactivity varies depending on the definition considered. Although several clinical variables resulted as independent predictors of detrusor underactivity, instrumental evaluation still plays a key role in the diagnosis.

INSIDIA 2.0 High-Throughput Analysis of 3D Cancer Models: Multiparametric Quantification of Graphene Quantum Dots Photothermal Therapy for Glioblastoma and Pancreatic Cancer.

Cancer spheroids are in vitro 3D models that became crucial in nanomaterials science thanks to the possibility of performing high throughput screening of nanoparticles and combined nanoparticle-drug therapies on in vitro models. However, most of the current spheroid analysis methods involve manual steps. This is a time-consuming process and is extremely liable to the variability of individual operators. For this reason, rapid, user-friendly, ready-to-use, high-throughput image analysis software is necessary. In this work, we report the INSIDIA 2.0 macro, which offers researchers high-throughput and high content quantitative analysis of in vitro 3D cancer cell spheroids and allows advanced parametrization of the expanding and invading cancer cellular mass. INSIDIA has been implemented to provide in-depth morphologic analysis and has been used for the analysis of the effect of graphene quantum dots photothermal therapy on glioblastoma (U87) and pancreatic cancer (PANC-1) spheroids. Thanks to INSIDIA 2.0 analysis, two types of effects have been observed: In U87 spheroids, death is accompanied by a decrease in area of the entire spheroid, with a decrease in entropy due to the generation of a high uniform density spheroid core. On the other hand, PANC-1 spheroids' death caused by nanoparticle photothermal disruption is accompanied with an overall increase in area and entropy due to the progressive loss of integrity and increase in variability of spheroid texture. We have summarized these effects in a quantitative parameter of spheroid disruption demonstrating that INSIDIA 2.0 multiparametric analysis can be used to quantify cell death in a non-invasive, fast, and high-throughput fashion.
