RÉSUMÉ
The German Biosecurity Programme was launched in 2013 with the aim to support partner countries overcome biological threats including natural outbreaks or the intentional misuse of highly pathogenic agents. As part of this programme, this paper describes the development and implementation of a multilateral biosafety and biosecurity training initiative, called 'Global Partnership Initiated Biosecurity Academia for Controlling Health Threats' (GIBACHT). To achieve its objectives, GIBACHT implemented a blended-learning approach with self-directed, distance-based learning phases and three training-of-trainer workshops. The programme follows Kirkpatrick's model of learning to guarantee sustainable effects of improved knowledge and skills. One hundred nine fellows from 26 countries have been trained in seven cohorts. Many GIBACHT alumni have established additional biosafety/biosecurity trainings in their home countries. The knowledge exchange is strengthened by the implementation of a Moodle-based alumni network. GIBACHT has the potential to contribute to strengthening the capacities of partner countries in Africa, the Middle East, and South and Central Asia to respond and build resilience to biological threats.

Introduction: Transobturator techniques are frequently used for the surgical treatment of female stress urinary incontinence (SUI), due to their high success rates and few intraoperative complications. However, controversial results have been reported in the literature regarding their incidence. The aim of this study is to analyze the real incidence and trend over time of such complications, especially voiding dysfunctions and overactive bladder (OAB) symptoms. Methods: A comprehensive search using PubMed/MEDLINE, Scopus, and Cochrane databases was performed. The search string used was the following: (female stress urinary incontinence) AND (complication) AND ((midurethral sling) OR (transobturator tape) OR (TVT-O) OR (voiding dysfunctions) OR (de novo OAB) OR (recurrent UTI) OR (vaginal erosion)). We included randomized controlled trials, prospective controlled studies, prospective and retrospective observational studies. All selected articles were screened based on titles and abstracts. Relevant data were extracted and tabulated. Results: A total of 39 studies were included in our analysis. Transobturator tape procedures show a high objective cure rate for SUI, from 76.9% to 100%. Postoperative voiding dysfunctions are shown to be quite common, ranging from 0-22% of cases. Despite that, this percentage decreases to 0-1% after 12 months. De novo OAB incidence ranges from 3% to 14% at 12 months, with variability over time due to multiple factors. Tape-related complications usually occur after 12 months, with a variable incidence up to 7%. Urinary tract infections (UTIs) are quite common in the immediate postoperative period but sometimes can be recurrent, requiring long-term prophylactic antibiotic treatment. Conclusions: Voiding dysfunctions are generally transient complications, while de novo OAB may persist over time. An adequate preoperative counseling, along with accurate written informed consent, could enhance patient tolerance of these issues and contribute to long-term patient satisfaction.

OBJECTIVE: This descriptive study examines quality of life in women undergoing placement of a midurethral sling for stress urinary incontinence. MATERIALS AND METHODS: This was a retrospective cohort study based on data from 51 women consecutively undergoing this procedure at a tertiary hospital in the years 2014 and 2015. The main outcome variable was quality of life assessed through the Sandvick severity test and International Consultation on Incontinence Short Quality of Life Questionnaire (ICIQ-IU-SF) at the time points baseline or presurgery, and 6 months and 5 years postsurgery. Factors associated with treatment failure were determined through binary logistic regression. RESULTS: At 5-year follow up we obtained an absolute reduction of 8.78 points (95% CI 6.43-11.14; pâ¯<â¯0.001) in the ICIQ-IU-SF questionnaire and 4.54 (95% CI 3.25-5.83; pâ¯<â¯0.001) in the Sandvick severity test score, compared to baseline, in the 35 patients that completed follow-up. Out of the 51 patients that were followed, the rate of success in incontinence correction was 86.3% (44/50) with a failure rate of 12% (6/50). Multiparity and previous gynaecological surgery were identified as predisposing factors for treatment failure. Obesity was associated with a worse treatment outcome. CONCLUSION: Sling treatment for incontinence was successful in 86.3% (44/50) of participants and remained effective 5 years after surgery in terms of quality of life.

BACKGROUND: Breastfeeding has a positive impact on child and maternal health outcomes. Black and Latina women and adolescent mothers have lower rates of breastfeeding initiation and continuance in the U.S. Maternal depression and psychosocial stressors may contribute to reduced rates of breastfeeding. The current study aims to better understand behaviours and associated factors related to breastfeeding in a diverse group of adolescent mothers attending a teen-tot clinic for postpartum and infant well care. METHODS: Participants were 191 mother-infant dyads. Mother's age ranged from 13 to 25, and 54% of mothers identified as Latina, 22% Black, 11% more than one race and 5% white. Demographic information and breastfeeding behaviour were abstracted from the medical record. Rates of postpartum mood/anxiety symptoms and psychosocial stressors were obtained from screening measures completed at medical visits. RESULTS: Analyses revealed that 87% of adolescent mothers in the sample initiated breastfeeding at birth and the racial/ethnic breakdown of those mothers closely mirrored the overall population (58% Hispanic or Latina, 17% Black, 10% more than one race, 5% white). At 2 months postpartum, only 41% of the population was still breastfeeding. Mothers with significant mood/anxiety symptoms at the newborn visit were more likely to be breastfeeding at the 1- and 2-month visits. Mothers with psychosocial stressors at the newborn visit were less likely to be breastfeeding at the 1- and 2-month visits. CONCLUSION: Efforts to promote health equity through breastfeeding for at-risk mothers must occur within the first few weeks postpartum and must consider associated factors including postpartum mood/anxiety symptoms and psychosocial stressors.

Currently, with the rapid growth of online media, more people are obtaining information from it. However, traditional hotspot mining algorithms cannot achieve precise and fast control of hot topics. Aiming at the problem of poor accuracy and timeliness in current news media hotspot mining methods, this paper proposes a hotspot mining method based on the co-occurrence word model. First, a new co-occurrence word model based on word weight is proposed. Then, for key phrase extraction, a hotspot mining algorithm based on the co-occurrence word model and improved smooth inverse frequency rank (SIFRANK) is designed. Finally, the Spark computing framework is introduced to improve the computing efficiency. The experimental outcomes expresses that the new word discovery algorithm discovered 16871 and 17921 new words in the Weibo Short News and Weibo Short Text datasets respectively. The heat weight values of the keywords obtained by the improved SIFRANK reaches 0.9356, 0.9991, and 0.6117. In the Covid19 Tweets dataset, the accuracy is 0.6223, the recall is 0.7015, and the F1 value is 0.6605. In the President-elects Tweets dataset, the accuracy is 0.6418, the recall is 0.7162, and the F1 value is 0.6767. After applying the Spark computing framework, the running speed has significantly improved. The text mining news media hotspot mining method based on the co-occurrence word model proposed in this study has improved the accuracy and efficiency of mining hot topics, and has great practical significance.
RÉSUMÉ
PURPOSE: We aimed to review the literature regarding the effects of trans obturator tape surgery (TOT) on sexual functions in women with stress urinary incontinence (SUI) to reveal compact data and to reach more consistent and reliable results. METHODS: PRISMA statement was used in the current review. The databases of PubMed (Medline), Science Direct, and Cochrane Central Register of Controlled Trials were detected independently. We evaluated the studies comparing the preoperative and postoperative sexuality parameters related to the TOT procedure in females. Studies presenting the mean and standard deviation(SD) of global and sub-item Female Sexual Function Index(FSFI) were included in the current study. RESULTS: We identified 783 studies in full publications or abstract forms using the methodology above and the search terms. Finally, eight studies were included in the meta-analysis. The pooled analysis of the mean difference demonstrated that the total sexual function scores of the patients improved after TOT surgery. CONCLUSION: The data collected from the current meta-analysis suggest that TOT surgery improves female sexual function.

BACKGROUND: Over the past five years, ultrafast high-frequency (HF) readout concepts have advanced the timing performance of silicon photomultipliers (SiPMs). The shown impact in time-of-flight (TOF) techniques can further push the limits in light detection and ranging (LiDAR), time-of-flight positron-emission tomography (TOF-PET), time-of-flight computed tomography (TOF-CT) or high-energy physics (HEP). However, upscaling these electronics to a system-applicable, multi-channel readout, has remained a challenging task, posed by the use of discrete components and a high power consumption. To this day, there are no means to exploit the high TOF resolution of these electronics on system scale or to measure the actual timing performance limits of a full detector block. METHODS: In this work, we present a 16-channel HF readout board, including leading-edge discrimination and a linearized time-over-threshold (TOT) method, which is fully compatible with a high-precision time-to-digital converters (TDCs), such as the picoTDC developed at CERN. The discrete implementation allows ideal adaptation of this readout to a broad range of detection tasks. As a first step, the functionality of the circuit has been tested using the TOFPET2 ASIC as back-end electronics to emulate the TDC, also in view of its properties as a highly scalable data acquisition solution. RESULTS: The produced board is able to mitigate influences of baseline shifts in the TOFPET2 front end, which has been shown in experiments with a pulsed laser, increasing the achievable intrinsic coincidence timing resolution (CTR) of the TOFPET2 readout electronics from 70 ps (FWHM) to 62 ps (FWHM). Single-channel coincidence experiments including a [Formula: see text]-source, 2[Formula: see text]2[Formula: see text]3 mm[Formula: see text] LYSO:Ce,Ca crystals and Broadcom NUV-MT SiPMs resulted in a CTR of 118 ps (FWHM). For a 4[Formula: see text]4 matrix of 3.88[Formula: see text]3.88[Formula: see text]19 mm[Formula: see text] LYSO:Ce,Ca crystals one-to-one coupled to a 4[Formula: see text]4 array of Broadcom NUV-MT SiPMs, an average CTR of 223 ps (FWHM) was obtained. CONCLUSION: The implemented 16-channel HF electronics are fully functionall and have a negligible influence on the timing performance of the back-end electronics used, here the TOFPET2 ASIC. The ongoing integration of the picoTDC with the 16-channel HF board is expected to further set the path toward sub-100 ps TOF-PET and sub-30ps TOF resolution for single-photon detection.
RÉSUMÉ
Urethral mesh placement has become a common surgical intervention for the management of stress urinary incontinence. While this procedure offers significant benefits, it is not without potential complications. This review article aims to provide a comprehensive overview of urethral mesh assessment in oncologic patients. The article explores normal magnetic resonance imaging (MRI) and computed tomography (CT) mesh appearances and highlights the pathological aspects associated with urethral mesh complications including both short-term and long-term post-operative complications. By understanding the spectrum of normal findings of urethral mesh and the possible complications, clinicians can improve patient outcomes and make informed decisions regarding urethral mesh management in this patient population.
RÉSUMÉ
The art of teaching in undergraduate and post graduate medical curriculum was revised in last century with targeted programs to equip the medical faculty with advanced teaching technologies. Medical education units (MEUs) were established by the medical council to train the existing medical faculty of the country in teaching methodologies. This study aimed to evaluate the MEU's impact on teachers' training and compare the status of trained teachers before and after the MEU era. Published literature and statistics on the MCI website were compiled to compare teachers' training status over time empirically. MEU, R.C., and N.C. have been highly efficient in improving the proportion of teachers trained from 5.38 to 50.32% across the country, especially after the upgradation of MEU in 2009. Proportion of the teachers trained increased from 5.38% to 50.32% due to the programs organized by various MEU, regional and nodal centres, especially after the upgradation of MEU in 2009. Lack of trained resource persons and administrative support were the common challenges faced. Properly organized MEU and planned activities should be emphasized in every institute. for effective development of the faculties.

Background: Stress urinary incontinence (SUI) that has been associated with abnormal pelvic floor muscle function or morphology is a common condition. This research aimed to study the impact of the four-dimensional (4D) pelvic floor ultrasound on the treatment of female patients with clinical diagnosis of SUI and to evaluate its clinical significance on SUI. Methods: We enrolled 51 women with SUI. Before transobturator suburethral tape procedures, the patients underwent 4D pelvic floor ultrasonography. The measurements include residual urine volume, bladder detrusor thickness in resting state, the vertical distance from the bladder neck to the posterior inferior edge of pubic symphysis at rest and Valsalva movement, posterior angle of bladder urethra, and urethral rotation angle. The degree of movement of the bladder neck (the difference between the vertical distance from the bladder neck to the posterior inferior edge of the pubic symphysis under the resting state and the maximum Valsalva movement) and the formation of a funnel at the internal orifice of the urethra were calculated. Results: The mean bladder detrusor thickness was 2.6 ± 0.9â mm, the vertical distance from the bladder neck to the posterior inferior edge of pubic symphysis was 27.7 ± 4.5â mm, the posterior angle of the bladder was 122.7 ± 18.9°, the vertical distance from the rectal ampulla to the posterior inferior edge of pubic symphysis was 18.5 ± 4.6â mm, and the mean area of hiatus of the levator ani muscle was 22.1 ± 6.0â cm2. The mean posterior angle of the bladder on Valsalva was 159.3 ± 23.1°, and the mean urethral rotation angle was 67.2 ± 21.4°. Conclusions: The 4D pelvic floor ultrasound is a reliable method in evaluating preoperational morphological characteristics of patients with SUI. With the help of the 4D pelvic floor ultrasound, the individualized treatment regimen can be developed and, more importantly, the inappropriate surgical decision can be avoided.

Operating room (OR) turnover time (TOT) is the time it takes to prepare an OR for the next surgery after the previous one has been completed. Reducing OR TOT can improve the efficiency of the OR, reduce costs, and improve surgeons' and patients' satisfaction. The objective of this study is to evaluate the effectiveness of an operating room (OR) turnover time (TOT) reduction initiative using the Lean Six Sigma methodology (DMAIC) in the bariatric and thoracic service lines. Performance improvement strategies consist of simplifying steps (surgical tray optimization) and concurrent steps (parallel task execution). We compared 2-month pre-implementation vs. post-implementation. A paired t-test was used to assess whether the difference in the measurements was statistically significant. The study found that TOT was reduced by 15.6% from an average of 35.6 ± 8.1 to minutes 30.09 ± 9.7 min (p < 0.05). Specifically, in the bariatric service line, TOT was reduced by 17.15% and in the thoracic service line, TOT was reduced by 9.6%. No adverse events related to the initiative were reported. The results of this study indicate that the TOT reduction initiative was effective in reducing TOT. The efficient use of operating rooms is crucial in hospital management, as it not only impacts finances but also affects the satisfaction of surgical teams and patients. This study shows the effectiveness of Lean Six Sigma methodology in reducing TOT and improving the efficiency in the OR.

OBJECTIVE: To quantify the reduction in wound size and change in wound quality following low-cost topical oxygen therapy (TOT) in patients with acute traumatic musculoskeletal wounds of the foot and ankle. METHOD: This prospective interventional study included patients with acute traumatic musculoskeletal wounds of the foot and ankle of <3 weeks' duration after they had undergone debridement and required subsequent wound coverage. A sterile C-Arm cover was used to cover the wound and 100% oxygen was administered at 1 atm, at a rate of 10l/min for 90 minutes on each of four consecutive days, through a suction catheter connected to an oxygen cylinder. The cycle was repeated after a three-day break. Wound surface area (by plotting on graph paper) and wound quality (by modified wound infection checklist score and swabs for culture and Gram staining) were assessed before and after TOT application. RESULTS: The study cohort included 20 patients ≥18 years of age. There was a statistically significant (p<0.001) reduction in mean wound surface area from 79.3cm2 at baseline to 69.6cm2 after two cycles of TOT. The mean modified wound infection checklist score was 13.6 and 0.8, respectively, before and after two cycles of TOT, suggesting statistically significant improvement (p=0.02) in wound quality. All patients showed no growth in their wound culture after TOT. CONCLUSION: TOT appears to be a promising and cost-effective alternative in the management of traumatic wounds. However, future studies with larger sample sizes and control groups for comparison are needed to establish the benefit of TOT in acute traumatic musculoskeletal wounds.

Background and Objectives: The purpose of this study was to compare the complications, success rate and satisfaction of pelvic floor reconstruction after transobturator midurethral sling (TOT) and TOT combined with pelvic floor reconstruction in the treatment of female stress urinary incontinence. To explore the pathogenesis of stress urinary incontinence after pelvic floor stress injury and improve the surgical treatment strategy. Materials and Methods: From 15 August 2018 to 24 February 2022, patients diagnosed with stress urinary incontinence (SUI) and secondary prolapse of the anterior pelvis were selected to receive surgically. Participants were followed up and evaluated at 2 months, 6 months and 1 year after treatment. According to the patient's chief complaint, the patient can urinate automatically without incontinence. The number of urinary incontinence and urine leakage was significantly reduced compared with those before operation. Urinary incontinence symptoms did not improve or worsen as ineffective, observing the efficacy and complications. Results: We included 191 patients in the TOT group and 151 patients in the pelvic floor reconstruction group after TOT was combined. The operation time and hospital stay in the TOT group were short, but the TOT group needed a second operation to treat recurrent SUI. Perioperative complications were mostly dysuria, and the incidence of postoperative complications in the group of TOT combined with pelvic floor reconstruction was low. The complete success rate and effective rate of pelvic floor reconstruction after TOT in the merger group were significantly higher than those in the TOT group, and the patient satisfaction and complete success rate were also higher. Conclusions: TOT combined with posterior pelvic floor reconstruction has a definite short-term effect on patients with SUI and anterior pelvic secondary prolapse. The operation design should pay attention to the support of the posterior wall of the perineum to the bladder neck and the middle and proximal end of the urethra.

【Objective】 To analyze the causes of the failure of previous operations in female patients with stress urinary incontinence (SUI), and to evaluate the efficacy and safety of modified transobturator outside-in tape (TOT). 【Methods】 A total of 42 female SUI patients who had failed in previous anti-incontinence surgery during Aug.2016 and Jul.2022 were enrolled. The causes of failure were analyzed. All patients were treated with modified TOT, and the operation time, estimated blood loss, duration of catheterization, symptom improvement and complications were observed. The outcomes were evaluated with the International Consultation on Incontinence Questionnaire Short Form (ICI-Q-SF), pad test and urodynamic study. 【Results】 All operations were technically successful. The average operation time was (32.4±18.6) min, and estimated blood loss was (54.2±34.5) mL. There were no obvious complications. After operation, the ICI-Q-SF score significantly decreased (P0.05). The overall effective rate was 88.1%. 【Conclusion】 Modified TOT can be used for the treatment of patients with failed anti-SUI surgery, which is simple and easy to perform, with a low complication rate and satisfactory postoperative results.
RÉSUMÉ
The tip-of-the-tongue (TOT) state is a spontaneously occurring metacognitive state that indicates that the answer to a query is almost, but not quite, at hand, i.e., that resolution is imminent. Since the time of William James, a distinctive feeling of nagging frustration has been observed to be associated with TOT states. On a more positive note, TOT states are also associated with intense goal-directed curiosity and with a strong desire to know that translates into successful mental action. The present study showed that prior to the presentation of resolving feedback to verbal queries-if the individual was in a TOT state-alpha suppression was in evidence in the EEG. This alpha suppression appears to be a marker of a spontaneously occurring, conscious, and highly motivating goal-directed internal metacognitive state. At the same time, alpha expression in the same time period was associated with the feeling of not knowing, indicating a more discursive state. Both alpha and alpha suppression were observed broadly across centro-parietal scalp electrodes and disappeared immediately upon presentation of the resolving feedback. Analyses indicated that the occurrence of alpha suppression was associated with participants' verbal affirmations of being in a TOT state, which is also related to subsequent expression of a late positivity when feedback is provided, and to enhanced memory.
RÉSUMÉ
Background and Objectives: pseudo urgency syndrome among patients with mixed incontinence (MUI) causes and the corresponding treatment strategies is explored. Materials and Methods: A total of 40 patients with MUI are treated with transobturator tape (TOT) and/or solifenacin succinate. Further, 30 patients with simple stress urinary incontinence (SUI) that were treated with transobturator tape (TOT) from the period of December 2018 to August 2020 are retrospectively analyzed; then, their clinical characteristics and therapeutic effects were summarized and analyzed. Results: The effective rates of SUI symptoms in MUI and simple SUI groups were 85% and 90%, respectively; further, the difference was noted as not statistically significant (P > 0.05). Among the 40 patients with MUI, 12 patients had unstable bladder contraction, and the other 28 patients showed normal bladder compliance. The treatment effectiveness rates of SUI symptoms in patients with unstable bladder contraction and normal bladder compliance were 83.3% and 85.7%, respectively; further, no significant difference was noted (P > 0.05). However, the effective rates of urge urinary incontinence (UUI) were 50% and 85.7%, respectively, however the difference was noted as statistically significant (P < 0.05). Conclusions: Most of the UUI symptoms in MUI patients may be "pseudo urgency syndrome" caused by the worry about the leakage of urine, rather than a real sense of UUI that is caused by excessive bladder excitement. Direct surgical treatment in patients with MUI can improve the symptoms of urinary incontinence, and the effect is more obvious in patients with urinary frequency who have normal bladder compliance according to urodynamics.

To clarify the feeling of knowing a name but not being able to recall it, known as having a "tip-of-the-tongue" (TOT) experience, we proposed a TOT model consisting of three stages combining a face recognition model and autonomic sympathetic nerve activity. Since TOT increases with age, we compared two age groups: young (N = 27, M = 20.4 ± 1.5 years) and middle-aged (N = 29, M = 58.5 ± 8.0 years). Experiment 1 showed that successfully naming low-frequency common names increased the skin conductance response (SCR) value, and the time to reach the maximum SCR value was longer. Experiment 2 was a naming task for face photographs. The younger group showed higher SCR values during successfully naming, while the middle-aged group showed similar SCR values for successfully naming and experiencing TOT. Both groups had the longest time to reach maximum SCR in TOT. In this study, physiological arousal of TOT was not affected by aging.

Conventional wisdom suggests mid-task rest as a potential approach to relieve the time-on-task (TOT) effect while accumulating evidence indicated that acute exercise might also effectively restore mental fatigue. However, few studies have explored the neural mechanism underlying these different break types, and the results were scattered. This study provided one of the first looks at how different types of fatigue-recovery break exerted influence on the cognitive processes by evaluating the corresponding behavioral improvement and neural response (EEG power spectral) in a sustained attention task. Specifically, 19 participants performed three sessions of psychomotor vigilance tasks (PVT), with one session including a continuous 30-min PVT while the other two sessions additionally inserted a 15-min mid-task cycling and rest break, respectively. For behavioral performance, both types of break could restore objective vigilance transiently, while subjective feeling was only maintained after mid-task rest. Moreover, divergent patterns of EEG change were observed during post-break improvement. In detail, relative theta decreased and delta increased immediately after mid-task exercise, while decreased delta was found near the end of the rest-inserted task. Meanwhile, theta and delta could serve as neurological indicators to predict the reaction time change for exercise and rest intervention, respectively. In sum, our findings provided novel evidence to demonstrate divergent neural patterns following the mid-task exercise and rest intervention to counter TOT effects, which might lead to new insights into the nascent field of neuroergonomics for mental fatigue restoration.
RÉSUMÉ
Importance: It needs to be clarified whether trans-obturator tape (TOT)-enhanced urethral resistance could impact the voiding function. Objective: Although TOT has been well-recognized for enhancing urethral resistance to restore continence in stress urinary incontinence (SUI) patients, whether the bladder's voiding functions adapt to the TOT-enhanced resistance has not been adequately investigated. This study thereby aimed to investigate whether TOT impacts the bladder's thermodynamic efficacy during the voiding phase. Design: A retrospective analysis of urodynamics performed before and after TOT was assessed. Setting: A tertiary referral hospital in Taiwan. Participants: A total of 26 female SUI patients who underwent urodynamic investigations before and after TOT. Main outcomes and measures: The area enclosed by the pressure-volume loop (Apv), which represents the work performed by the bladder during voiding, in a pressure-volume analysis established by plotting the detrusor pressure versus intra-vesical volume was retrospectively analyzed. Paired Student's t-tests were employed to assess the difference in values before and after the operation. Significance in difference was set at p < 0.05. Results: TOT increased Apv in 20 of 26 (77%) patients and significantly increased the mean Apv compared to the preoperative control (2.17 ± 0.18 and 1.51 ± 0.13 × 103 cmH2O-ml, respectively p < 0.01). TOT also increased the mean urethral resistance (1.03 ± 0.30 vs. 0.29 ± 0.05 cmH2O-sec/ml, p < 0.01) and mean voiding pressure (25.87 ± 1.72 and 19.30 ± 1.98 cmH2O p < 0.01) but did not affect the voided volume and voiding time. Moreover, the TOT-induced Apv increment showed a moderate correlation with the changes in urethral resistance and voiding pressure (both r > 0.5) but no correlation with changes in voided volume or voiding time. It is remarkable that the TOT-induced urethral resistance increment showed a strong correlation with changes in voiding pressure (r > 0.7). Conclusion and Relevance: The bladder enhances thermodynamic efficacy by adapting the voiding mechanism to increased urethral resistance caused by TOT. Further studies with higher case series and longer follow-ups should assess whether this effect could be maintained over time or expire in a functional detrusor decompensation, to define diagnostic criteria that allow therapeutic interventions aimed at its prevention during the follow-up.
