Laryngeal office-based procedures: A safe approach

PURPOSE

Laryngeal surgeries using a flexible nasopharyngoscope equipped with an operative channel has gained popularity, with gradual increase in the variety of interventional office-based procedures, under local anesthesia. The purpose of this study is to analyze the tolerance of such procedures.

MATERIALS AND METHODS

Retrospective cohort study. 337 cases were performed during 2 years. We collected the following data: type of pathology, type of procedure and modalities of anesthesia, adverse events.

RESULTS

19 % of the visits were for the purpose of Biopsy, 65 % for an injection, and Trublue Laser was utilized in 12 % of the procedures. Regarding the pathologies, 27 % were vocal fold paralysis, 18 % leukoplakia or another suspicious lesion, 15 % recurrent respiratory papillomatosis, 13 % neuromuscular disorder, 9 % vocal fold scarring, 7 % vocal cord atrophy and 6 % had an inflammatory presentation. Side effects were documented in 26 visits (7.7 %) and were minor in almost all the encounters: they included strong reflexive cough, deep throat pain, discomfort, gag reflex, anxiety, vagal discomfort, malaise, hypersalivation, nose pain, labile hypertension. More severe side effects were very rare and included septal wound and epistaxis, erythematous rash, dyspnea, and transient dysarthria. 13 procedures were either aborted, or canceled at initial steps, due to inability of the patient to tolerate the procedure and were rescheduled for general anesthesia. 97 % of the cases were released home after 1 h of surveillance.

CONCLUSION

Office-based flexible interventional laryngoscopy under local anesthesia is a safe and well-tolerated procedure, with abundance of various interventions feasible on ambulatory, office-based setup.

Effectiveness of a two-stage strategy using the 16-item Prodromal Questionnaire (PQ16/fPQ16) and the Comprehensive Assessment of At Risk Mental States (CAARMS) in the early detection of Ultra High Risk (UHR) patients in Lebanon: a cross-sectional pilot study

OBJECTIVES

This study aims to identify the prevalence of Ultra High Risk (UHR) adults in a sample of patients in Lebanon and to compare screening and diagnostic tools.

METHODS

This is a cross-sectional pilot study which targeted patients aged 17-30 years willingly seeking psychiatric care in a university hospital in Beirut, Lebanon. Participants were invited to fill either the English or the French version of the Prodromal Questionnaire (respectively, PQ16 or fPQ16). The abbreviated version of the "Comprehensive Assessment of At-Risk Mental States" (CAARMS) was then administered to all participants. The latter were subsequently sorted into one of the three UHR groups - vulnerability group, attenuated psychosis (APS), intermittent psychosis (BLIPS) - or were diagnosed as suffering from a psychotic disorder.

RESULTS

Thirty-one patients participated in this study. The prevalence of positive screening on the PQ16/fPQ16 and positive diagnosis of UHR on the CAARMS were respectively of 61.29% and 45%. The APS group was the most prevalent (71.42%). A positive psychosis screening on PQ16/fPQ16 was statistically related to a UHR diagnosis on CAARMS (p-value: 0.011 on Chi2 test), OR=8.5 (95% CI: 1.4-50.9; p-value: 0.018). No relation was found between PQ16/fPQ16 results and risk stratification or between the number of "True" responses on PQ16/fPQ16 and the intensity of symptoms on CAARMS. PQ16/fPQ16 statements 5, 9, 11 and 16 predicted a UHR diagnosis on CAARMS (p-value of 0.045, 0.006, 0.045 and 0.045, respectively).

CONCLUSION

This two-stage strategy for identifying UHR patients can be adopted in a tertiary health care center.

Association between frailty and detrusor overactivity with detrusor underactivity in older women

PURPOSE

While detrusor overactivity (DO) with detrusor underactivity (DU) (DO-DU) has been described as typical of aging, the pathogenesis of DO-DU is highly multifactorial, and often thought to involve medical conditions beyond the urinary tract. We aimed to explore potential associations between idiopathic DO-DU and frailty in older women after accounting for age.

METHODS

The design of the study is a cross-sectional single-center study, in an outpatient urodynamic unit specializing in geriatrics. Participants are consecutive female patients aged ≥65 years without contributory neurological conditions or bladder outlet obstruction who completed a comprehensive geriatric assessment followed by urodynamic evaluation from 2015 to 2019. Participants were categorized as having DO, DU, combined DO-DU, or a negative study. Multinomial logistic regression analysis was used to assess the relationship between urodynamic outcomes and frailty, as quantified using the Frailty index (FI).

RESULTS

Ninety-five patients were included (median age 78 [interquartile range: 70-83] years), among whom 29% had combined DO-DU. The median FI score was 0.27 (0.2-0.32) (5-12). A higher FI was associated with significantly greater age-adjusted odds of DO-DU when either DU or subjects with a negative urodynamic assessment were used as the reference group. Age was not significantly associated with DO-DU across all multivariable analyses.

CONCLUSION

A higher FI was associated with an increased likelihood of DO-DU, which could not be attributed to the effect of age alone. The pathogenesis of DO-DU is likely more complex than chronological aging in and of itself and merits further study.

The role of renal circadian biorhythms in lifelong LUTS

INTRODUCTION

This article delves into the intricate relationship between kidney function, diuresis, and lower urinary tract symptoms (LUTS) throughout the transitions of the human lifespan. It explores circadian regulation of urine production, maturation of renal function from birth to adulthood, and effects of aging on kidney function and LUTS. The complex connections between these factors are highlighted, offering insights into potential interventions and personalized management strategies.

METHODS

An international panel of seven experts engaged in online discussions, focusing on kidney function, diuresis, and LUTS throughout life. This manuscript summarizes expert insights, literature reviews, and findings presented during a webinar and subsequent discussions.

RESULTS

Renal function undergoes significant maturation from birth to adulthood, with changes in glomerular filtration rate, diuresis, and tubular function. A circadian rhythm in urine production is established during childhood. Adolescents and young adults can experience persistent enuresis due to lifestyle factors, comorbidities, and complex physiological changes. In older adults, age-related alterations in kidney function disrupt the circadian rhythm of diuresis, contributing to nocturnal polyuria and LUTS.

CONCLUSION

The interplay between kidney function, diuresis, and LUTS is crucial in understanding lifelong urinary health. Bridging the gap between pediatric and adult care is essential to address enuresis in adolescents and young adults effectively. For older adults, recognizing the impact of aging on renal function and fluid balance is vital in managing nocturia. This holistic approach provides a foundation for developing innovative interventions and personalized treatments to enhance quality of life for individuals with LUTS across all stages of life.

Durvalumab with or without tremelimumab versus the EXTREME regimen as first-line treatment for recurrent or metastatic squamous cell carcinoma of the head and neck: KESTREL, a randomized, open-label, phase III study

BACKGROUND

Patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) have a poor prognosis. The phase III KESTREL study evaluated the efficacy of durvalumab [programmed death-ligand 1 (PD-L1) antibody] with or without tremelimumab [cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) antibody], versus the EXTREME regimen in patients with R/M HNSCC.

PATIENTS AND METHODS

Patients with HNSCC who had not received prior systemic treatment for R/M disease were randomized (2 : 1 : 1) to receive durvalumab 1500 mg every 4 weeks (Q4W) plus tremelimumab 75 mg Q4W (up to four doses), durvalumab monotherapy 1500 mg Q4W, or the EXTREME regimen (platinum, 5-fluorouracil, and cetuximab) until disease progression. Durvalumab efficacy, with or without tremelimumab, versus the EXTREME regimen in patients with PD-L1-high tumors and in all randomized patients was assessed. Safety was also assessed.

RESULTS

Durvalumab and durvalumab plus tremelimumab were not superior to EXTREME for overall survival (OS) in patients with PD-L1-high expression [median, 10.9 and 11.2 versus 10.9 months, respectively; hazard ratio (HR) = 0.96; 95% confidence interval (CI) 0.69-1.32; P = 0.787 and HR = 1.05; 95% CI 0.80-1.39, respectively]. Durvalumab and durvalumab plus tremelimumab prolonged duration of response versus EXTREME (49.3% and 48.1% versus 9.8% of patients remaining in response at 12 months), correlating with long-term OS for responding patients; however, median progression-free survival was longer with EXTREME (2.8 and 2.8 versus 5.4 months). Exploratory analyses suggested that subsequent immunotherapy use by 24.3% of patients in the EXTREME regimen arm contributed to the similar OS outcomes between arms. Grade 3/4 treatment-related adverse events (TRAEs) for durvalumab, durvalumab plus tremelimumab, and EXTREME were 8.9%, 19.1%, and 53.1%, respectively.

CONCLUSIONS

In patients with PD-L1-high expression, OS was comparable between durvalumab and the EXTREME regimen. Durvalumab alone, and with tremelimumab, demonstrated durable responses and reduced TRAEs versus the EXTREME regimen in R/M HNSCC.

The low dopamine hypothesis: A plausible mechanism underpinning residual urine, overactive bladder and nocturia (RON) syndrome in older patients

INTRODUCTION

Aging is associated with a combination of several lower urinary tract (LUT) signs and symptoms, including residual urine, overactive bladder and nocturia. One of the mechanisms of this LUT dysfunction that has not been discussed in dept so far is the role of dopamine (DA).

METHODS

In this narrative review, we explore the dopaminergic hypothesis in the development of this combination of LUT signs and symptoms in older adults.

RESULTS

DA is one of the neurotransmitters whose regulation and production is disrupted in aging. In synucleinopathies, altered DAergic activity is associated with the occurrence of LUTS and sleep disorders. Projections of DAergic neurons are involved in the regulation of sleep, diuresis, and bladder activity. The low dopamine hypothesis could explain the genesis of a set of LUT signs and symptoms commonly seen in this population, including elevated residual urine, Overactive bladder syndrome and Nocturia (discussed as the RON syndrome). This presentation is however also common in older patients without synucleinopathies or neurological disorders and therefore we hypothesise that altered DAergic activity because of pathological aging, and selective destruction of DAergic neurons, could underpin the presentation of this triad of LUT dysfunction in the older population.

CONCLUSION

The concept of RON syndrome helps to better understand this common phenotypic presentation in clinical practice, and therefore serves as a useful platform to diagnose and treat LUTS in older adults. Besides recognizing the synucleinopathy "red flag" symptoms, this set of multi-causal LUT signs and symptoms highlights the inevitable need for combination therapy, a challenge in older people with their comorbidities and concomitant medications.

In multiple sclerosis, a Functional Independence Measure ≥ 107 is the best predictor of outcome after clean intermittent catheterization training

BACKGROUND

Assessment of motor and cognitive functions is recommended before clean intermittent catheterization training. Two validated instruments, the Functional Independence Measure (FIM) and the Pencil and Paper Test (PP-Test), are associated with the ability to learn self-catheterization in people with multiple sclerosis.

OBJECTIVES

We aimed to compare the performance of these tools in predicting the outcome of clean intermittent catheterization training in multiple sclerosis.

METHODS

All people with multiple sclerosis attending a tertiary neuro-urology department between 2011 and 2019 and eligible for clean intermittent catheterization were included in this retrospective study. The reference standard was the ability to perform at least 2 trials of self-catheterization at the end of the training session. The 2 index tests, the FIM and PP-Test, were administered before the teaching session. Their diagnostic performance was estimated by calculating sensitivity, specificity, and area under the receiver operating characteristic curve (AUC). The AUC values were compared by a two-sided DeLong test.

RESULTS

We included 395 individuals (mean [SD] age 49.8 [12] years; 70% women). At the end of the session, 87% of the patients succeeded in learning self-catheterization. The optimal cut-offs for the FIM (107) and PP-Test (13) were estimated, resulting in sensitivity of 73% (95% confidence interval [68-77) and 73% (67-77) and specificity 73% (59-84) and 63% (49-76), respectively. The AUC values for the FIM and PP-Test were significantly different (0.79 vs 0.73, p = 0.049). The effect size was large for both the FIM (Cohen's d = 1.14) and PP-Test (Cohen's d = 0.87).

CONCLUSIONS

An FIM value ≥107 has the best specificity to predict outcome after clean intermittent catheterization training for people with multiple sclerosis. The sensitivity of the FIM and PP-Test is similar, and both have a large effect size for the outcome of self-catheterization training in multiple sclerosis.

Nocturia severely impairs the sleep quality of nursing home residents: results from a multi-center study

OBJECTIVES

To assess the association between self-reported sleep quality and nocturia in nursing home residents.

METHODS

The association between self-reported poor sleep quality and nocturia was examined in eighty nursing home residents from two nursing facilities using logistic regression analysis.

RESULTS

Poor sleep quality was reported by 29% of the eighty participants (median age 89±7 years, 77% of women). Nocturia was more frequent in patients with versus without self-reported poor sleep quality (78% vs 47%, p=0.01). Nocturia was independently associated with self-reported poor sleep quality after controlling for age, gender, self-rated health status, cognitive frailty score, antidepressant and hypnosedative use (OR[95%CI] of 6.1[1.8-25.4]).

CONCLUSION

Nocturia severely impaired sleep quality in nursing home residents. Nocturia should be investigated in nursing home residents to optimize sleep quality.

The Neurogenic Bowel Dysfunction score (NBD) is not suitable for patients with multiple sclerosis

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

Bowel and anorectal dysfunctions are common in patients with multiple sclerosis (pwMS). The use of validated questionnaires is recommended in the initial assessment and patient's follow-up. The Neurogenic Bowel Dysfunction (NBD) score is the most used questionnaire but has been developed in spinal cord injured patients and has never been validated in other neurological diseases. We aimed to assess NBD's relevance in pwMS.

SETTINGS

Monocentric study in a tertiary neuro-urology department.

METHODS

A retrospective study in pwMS consulting for the first time in our department, that fulfilled the NBD questionnaire between 2010 and 2021 was performed. Qualitative and quantitative answers for each question were analyzed. Content validity and internal consistency were evaluated.

RESULTS

One hundred thirty-five pwMS (mean age 47.1, 58% of women) fulfilled the NBD questionnaire. Mean NBD score was 6.0 (SD 6.1) and 75% of patients had a score <9. Content validity analysis revealed 4 items not appropriate, 1 item with irrelevant calibration, and omission of some treatment widely used in pwMS. Internal consistency was appreciated with Cronbach's alpha = 0.48 IC 95% [0.31; 0.6].

CONCLUSION

NBD questionnaire lacks content validity and presents a weak internal consistency in pwMS. A specific questionnaire is therefore required in pwMS to optimize bowel management and follow-up.

Aqua: A new questionnaire assessing anticholinergic side effects in neurogenic population (Aqua: Anticholinergic side effects questionnaire)

AIMS

Validate a new questionnaire to assess the side effects secondary to anticholinergics in neurogenic population suffering from Adult neurogenic lower urinary tract dysfunction (ANLUTD).

METHODS

We conducted a prospective, monocentric study in a Neuro-urology Department of a University Hospital between February 2015 and April 2020. To allow a full psychometric validation of a questionnaire, the study protocol included 3 steps: qualitative interviews, feasibility study and validation study. The primary outcome was good psychometric properties defined with good internal consistency reliability (Cronbach's α>0.7) and good test-retest reliability (intraclass correlation coefficient (ICC)>0.7).

RESULTS

we included 64 patients with ANLUTD secondary to neurogenic disorders. Feasibility study demonstrate very good acceptation and comprehension for 97% of patients. Validation study showed good internal consistency with Cronbach's α=0,69 and very good ICC=0,73. AQUA is composed with 8 items scoring 0 (no side effect) to 2 (major side effect) for a total score between 0 to 16. Time to fulfill is very quick. Mean score in our population was 4,1 (sd 2,9).

CONCLUSION

AQUA is the first validated tool to assess side effects secondary to antimuscarinic treatment for neurogenic population suffering from ANLUTD.

The prevalence of post-traumatic stress disorder in Syrian refugees increased after long-distance migration

Introduction

Refugees are forced migrants but there is a large variation in the distance that refugees cover and there is a knowledge gap on how this may affect refugees’ health and health care needs.

Objectives

Herein, we investigate the association between long-distance migration and post-traumatic stress disorder (PTSD), a serious psychiatric disorder associated with deteriorating mental and somatic health and highly prevalent in refugees.

Methods

Included were 712 adult Syrian refugees and asylum seekers in Lebanon and Denmark arriving no more than 12 months prior to inclusion. The Harvard Trauma Questionnaire was used to assess PTSD and the estimate of association was obtained by multiply imputing missing data and adjusting for confounding by propensity score-weighting with covariates age, sex, socioeconomic status, trauma experience, and WHO-5-score, reporting the bootstrap 95-percentile confidence interval (95% CI). Additionally, a number of sensitivity analysis were carried out.

Results

The prevalence of PTSD was high in both Lebanon (55%) and Denmark (60%) and long-distance migration was associated with a 9 percentage point (95% CI [-1; 19]) increase in the prevalence of PTSD among newly arrived Syrian refugees and asylum-seekers.

Conclusions

In the present study the prevalence of PTSD increased after long-distance migration which may support considering “long-distance migration” in refugee health screenings and in particular when assessing the risk of post-traumatic stress disorder. This is a first step in examining the health effects of migration on refugee health.

PURPOSE

During the COVID-19 pandemic, a care reorganization was mandatory, and affected patients in different areas, including management of neurogenic lower urinary tract dysfunction. This work aims to provide validated schedule concerning the assessment and management of patients in neuro-urology.

METHODS

Based on a literature review and their own expertise, a steering committee composed of urologists and physical medicine and rehabilitation practitioners generated a comprehensive risk-situation list and built a risk scale. A panel of French-speaking experts in neuro-urology was asked to define the timing for each clinical situation and validated these new recommendations through a Delphi process approach.

RESULTS

The 49 experts included in the rating group validated 163 propositions among the 206 initial items. The propositions were divided into four domains - diagnosis and assessment, treatment, follow-up, and complications - and two sub-domains - general (applicable for all neurological conditions) and condition-specific (varying according to the neurological condition (spinal cord injury, multiple sclerosis, brain injury, Parkinsonism, spinal dysraphism, lower motor neuron lesions)).

CONCLUSIONS

This multidisciplinary collaborative work generates recommendations based on expert opinion, providing a validated timing for assessment and management of patients in neuro-urology which may help clinicians to reorganize their patients' list with a personalized medicine approach, in a context of health crisis or not.

Fecal incontinence subtype assessment (FI-SA): A new tool to distinguish among subtypes of fecal incontinence in a neurogenic population

INTRODUCTION

Two subtypes of fecal incontinence (FI) are defined in the literature (urge and passive FI). The pertinence of this classification is unknown due to conflicting findings and heterogeneity of definitions. However, no questionnaire is available to clearly classify patients among subtypes. The objective of the present study was to develop and validate a new tool (Fecal incontinence subtype assessment, FI-SA) in order to better classify patients among the different subtypes of FI.

METHODS

A prospective monocentric study was conducted in consecutive patients with FI according to Rome IV criteria. To validate psychometric properties of the FI-SA questionnaire, a literature review and qualitative interviews were performed and discussed with an expert panel. A feasibility study was realized to assess acceptability and comprehension of items. The reproducibility was investigated in a validation study.

RESULTS

Comprehension and acceptability were excellent in 90% of patients in the feasibility study (n = 30). Validation study (n = 100) showed a good reproducibility with an intra-class correlation coefficient of 0.91 and 0.89 for questions 1 and 2. Time to fill the questionnaire was 40.0 s. 98.0% patients were classified among subtypes of FI: 34.0% passive FI, 32.0% urge FI and 32.0% mixed FI.

CONCLUSION

FI-SA is the first questionnaire to classify patients among subtypes of FI with good psychometric characteristics and the first questionnaire introducing the concept of mixed FI. FI-SA could help to determine the pertinence of this classification of FI in the management of these patients.

Is There a Relationship Between Overactive Bladder and Sexual Dysfunction in Women With Multiple Sclerosis?

BACKGROUND

Lower urinary tract Symptoms (LUTS) and Sexual dysfunction (SD) are common in women with MS and affect quality of life.

AIM

The aim of this study was to determine the relationship between sexual dysfunction (SD) and overactive bladder in women with Multiple Sclerosis (MS).

METHODS

From January 2019 to January 2021, we evaluated 89 female MS patients admitted for LUTS in a Neuro-Urology Department. SD was investigated using the Female Sexual Function Index (FSFI). All subjects completed the Urinary Symptom Profile scale (USP) and Hospital Anxiety and Depression Scale (HAD A/HAD D). Neurological impairment was assessed using the Expanded Disability Status Scale (EDSS). All patients underwent neurological examination and urodynamic studies. Univariate analysis and Multivariate logistic regression analysis were performed to identify predictors of SD in women with MS (FSFI <26.55).

OUTCOMES

Primary outcome was to determine the association between sexual dysfunction in women with MS and LUTS (overactive bladder, stress incontinence or voiding dysfunction).

RESULTS

Sexual dysfunction (FSFI<26,55) affected 74% of women with MS, even with low physical disabilities (EDSS<5). Univariate analysis showed that overactive bladder was more frequent in SD group, but no statistical difference was found (P < .12). No relationship was found between sexual dysfunction and stress incontinence (P = ,47), voiding dysfunction (P= 0.79) or urinary retention (P= .96). Multivariate logistic regression analysis identified overactive bladder to be an independent predictor of sexual dysfunction [aOR 0.03 (CI 0,0.98)]. Sexual dysfunction was not associated with detrusor overactivity on urodynamic studies or with impairment mobility but was strongly associated with the presence of depression (P < .01).

CLINICAL IMPLICATIONS

Sexual disorders in women with MS should be assessed as much as urinary disorder. STRENGTHS AND LIMITATIONS: this study included the largest cohort of women with MS. But the sample was obtained in an outpatient setting with low neurological impairment.

CONCLUSION

In our study, SD was frequent affecting young women with no anticholinergic treatment and low physical impairment. Overactive bladder seemed to be independent predictor of sexual dysfunction. Conversely, SD was not associated with detrusor overactivity, neurological impairment, or duration of disease but was strongly associated with depression. Breton FL, Chesnel C, Lagnau P, et al.

French version of the short form of neurogenic bladder symptom score: Cross-cultural adaptation and validation

Introduction: This study aimed to empirically validate a French version of the Neurogenic Bladder Symptoms Score-Short From (NBSS-SF), a psychometric multidimensional tool to assess lower urinary tract symptoms (LUTS) for patients with a neurological condition. Methods: One hundred and five participants with multiple sclerosis or spinal cord injury prospectively completed the questionnaire at baseline and 7–14 days later. The α coefficient of Cronbach (internal consistency) and the intraclass correlation coefficient (ICC) (test-retest reliability) were calculated. Results: The internal consistency for the overall questionnaire was high (Cronbach’s α coefficients from 0.79), while coefficients for each subscale were variable (urinary incontinence 0.91; storage and voiding 0.69; consequences 0.25). For test-retest reliability, 88/105 (84%) patients filled and sent back their questionnaire 10 days (±3.6 days) after baseline version. ICC was 0.90 for the total score and was 0.73 for the urinary incontinence subdomain, 0.79 for storage and voiding, and 0.75 for consequences. Conclusions: The psychometric qualities of the French version of the NBSS-SF are well-supported, thus providing a valid tool to measure bladder symptoms across three different domains in patients with a neurogenic bladder.

Upper urinary tract function of patients with multiple sclerosis

BACKGROUND

Neurogenic lower urinary tract dysfunction (NLUTD) is frequent in multiple sclerosis (MS) and renal prognosis is a key point of bladder management.

OBJECTIVE

To assess upper urinary tract damage risk using voiding cystourethrography (VCUG) in patients with (PwMS) and NLUTD.

METHODS

We conducted a retrospective study between 2010 and 2020. Demographic data, urinary symptoms, urinary tract infection (UTI), renal ultrasounds findings, glomerular filtration rate (GFR), VCUG data, and urodynamic parameters were collected in PwMS with NLUTD.

RESULTS

Among 325 PwMS included, 67% were female, mean age was 51.6 ± 12.0 years, and mean EDSS 4.6 ± 1.8. VCUG showed vesicoureteral reflux (VUR) in 18 patients. A link was found between VUR and progressive MS course (p = 0.04), hydronephrosis (odds ratio [OR] = 17.44; 95% confidence interval [CI] = 3.46-87.87; p = 0.001), low GFR (p < 0.001), and detrusor overactivity (p = 0.04). No association with UTIs, EDSS, detrusor sphincter dyssynergia, were elicited. On multivariate analysis, alteration of GFR was independently related to the presence of VUR (OR = 0.95; 95% CI = 0.92-0.98).

CONCLUSIONS

VUR elicited on VCUG is associated with lower GFR and hydronephrosis. However, due to the low prevalence (5.5%) of this abnormality in PwMS, VCUG should be performed in selected cases and not in routinary practice.

Recommendations on the management of pudendal nerve entrapment syndrome: A formalised expert consensus

BACKGROUND

Since the development and publication of diagnostic criteria for pudendal nerve entrapment (PNE) syndrome in 2008, no comprehensive work has been published on the clinical knowledge in the management of this condition. The aim of this work was to develop recommendations on the diagnosis and the management of PNE.

METHODS

The methodology of this study was based on French High Authority for Health Method for the development of good practice and the literature review was based on the PRISMA method. The selected articles have all been evaluated according to the American Society of Interventional Pain Physicians assessment grid.

RESULTS

The results of the literature review and expert consensus are incorporated into 10 sections to describe diagnosis and management of PNE: (1) diagnosis of PNE, (2) patients advice and precautions, (3) drugs treatments, (4) physiotherapy, (5) transcutaneous electrostimulations (TENS), (6) psychotherapy, (7) injections, (8) surgery, (9) pulsed radiofrequency, and (10) Neuromodulation. The following major points should be noted: (i) the relevance of 4+1 Nantes criteria for diagnosis; (ii) the preference for initial monotherapy with tri-tetracyclics or gabapentinoids; (iii) the lack of effect of opiates, (iv) the likely relevance (pending more controlled studies) of physiotherapy, TENS and cognitive behavioural therapy; (v) the incertitudes (lack of data) regarding corticoid injections, (vi) surgery is a long term effective treatment and (vii) radiofrequency needs a longer follow-up to be currently proposed in this indication.

CONCLUSION

These recommendations should allow rational and homogeneous management of patients suffering from PNE. They should also allow to shorten the delays of management by directing the primary care.

SIGNIFICANCE

Pudendal nerve entrapment (PNE) has only been known for about 20 years and its management is heterogeneous from one practitioner to another. This work offers a synthesis of the literature and international experts' opinions on the diagnosis and management of PNE.

Cortical, Spinal, Sacral, and Peripheral Neuromodulations as Therapeutic Approaches for the Treatment of Lower Urinary Tract Symptoms in Multiple Sclerosis Patients: A Review

INTRODUCTION

Multiple sclerosis (MS) is often associated with urological disorders, mainly urinary incontinence and retention, the management of which being necessary to improve patient's quality of life (QOL) and to reduce potential urological complications. Besides the classical treatments based mainly on anticholinergics and/or self-catheterization, several neuromodulation techniques have been tried in recent years to improve these urinary disorders. By this review, we aim at providing an overview of neuromodulation and electrostimulation approaches to manage urinary symptoms in MS patients.

MATERIALS AND METHODS

A literature search using MEDLINE was performed. Only papers in English, and describing the effects of neuromodulation in MS patients, were considered.

RESULTS

A total of 18 studies met inclusion criteria and were reviewed. Of them, four related to sacral neuromodulation (SNM), seven to percutaneous tibial nerve stimulation (PTNS), six to spinal cord stimulation (SCS), and one to transcranial magnetic stimulation (TMS).

DISCUSSION

PTNS and SNM seem to be effective and safe therapeutic options for treating lower urinary tract symptoms in MS patients principally in case of overactive bladder (OAB) symptoms. Similarly, also SCS and TMS have been shown to be effective, despite the very limited number of patients and the small number of studies found in the literature. Interestingly, these techniques are effective even in patients who do not respond well to conservative therapies, such as anticholinergics. Furthermore, given their safety and efficacy, stimulations such as PTNS could be considered as a first-line treatment for OAB in MS patients, also considering that they are often preferred by patients to other commonly used treatments.

Prioritization of risk situations in neuro-urology: guidelines from Association Française d'Urologie (AFU), Association Francophone Internationale des Groupes d'Animation de la Paraplégie (A.F.I.G.A.P.), Groupe de Neuro-urologie de Langue Française (GENULF), Société Française de Médecine Physique et de Réadaptation (SOFMER) and Société Interdisciplinaire Francophone d'UroDynamique et de Pelvi-Périnéologie (SIFUD-PP)

Purpose

The current health crisis has drastically impacted patient management in many fields, including neuro-urology, leading to a mandatory reorganization. The aim of this work was to establish guidelines regarding the prioritization and optimal timing of each step of neurogenic lower urinary tract dysfunction management.

Methods

A steering committee included urologists and physical medicine and rehabilitation practitioners. Based on a literature review and their own expertise, they established a comprehensive risk-situation list and built a risk scale, allowing multiple other experts to score each clinical situation. New recommendations were generated using a Delphi process approach.

Results

Forty-nine experts participated in the rating group. Among the 206 initial items, 163 were selected and divided into four domains, diagnosis and assessment, treatment, follow-up, and complications, and two sub-domains, general (applicable for all neurological conditions) and condition-specific [varying according to the neurological condition (spinal cord injury, multiple sclerosis, brain injury, Parkinsonism, dysraphism, lower motor neuron lesions)]. The resulted guidelines are expert opinions established by a panel of French-speaking specialists, which could limit the scalability of this work.

Conclusions

The present multidisciplinary collaborative work generates recommendations which complement existing guidelines and help clinicians to reorganize their patients’ list in the long term with a personalized medicine approach, in the context of health crisis or not.

Adherence to transanal irrigation in older adults: first-year assessment

BACKGROUND

While the prevalence of chronic constipation and fecal incontinence increases with age, few data on transanal irrigation in older adults are available. The aim of this study was to assess the adherence and predictive factors for adherence to transanal irrigation during the first year of use in older adults.

METHODS

This retrospective study included all patients over 65 years old, who had therapeutic education for transanal irrigation with the Peristeen® device between January 2010 and July 2019 in a neuro-urology department of a university hospital in France. The adherence rate was assessed at 1, 3, 6, and 12 months. Predictive factors for adherence were looked for by comparing persistent population and non-persistent population at 1, 3, 6, and 12 months.

RESULTS

Sixty-nine patients over 65 years old were included. The adherence rate was 73.9% at 1 month, 55.1% at 3 months, 46.4% at 6 months, and 40.1% at 1 year. No predictive factor for adherence to transanal irrigation was identified.

CONCLUSIONS

Adherence to transanal irrigation during the first year in older adults remains close to that in the adult general population. Predictive factors of adherence remain unclear.

Functional independence measure predicts the outcome of clean intermittent catheterization training in patients with multiple sclerosis

BACKGROUND

Clean intermittent catheterization (CIC) is the reference treatment of urinary retention in people with multiple sclerosis (pwMS). Predicting which patients could use this treatment, based on their motor and cognitive abilities, is crucial.

OBJECTIVES

To determine whether the Functional Independence Measure (FIM), used to assess degree of disability, can predict the outcome of CIC training in pwMS.

METHODS

All pwMS attending a tertiary neurourology department between 2011 and 2019 and eligible for CIC were included in this retrospective study. Level of disability was assessed with the FIM by an occupational therapist. Success for learning CIC, defined as the ability to perform at least 2 trials of the technique, was recorded at the end of the session by a continence nurse and a physiatrist. The association between the FIM and success for learning CIC was assessed by multivariable analysis.

RESULTS

We included 395 patients (mean [SD] age 49.8 [12.0] years; 70% women). More than half of patients had relapsing-remitting disease, and the Expanded Disability Status Scale score was ≥ 6. Mean FIM total, motor and cognitive scores were 108.0 (14.2), 75.9 (12.3) and 32.1 (3.7), respectively (maximal scores: 126, 91 and 35). At the end of the session, 87% of patients were successful in learning CIC. After adjustment of potential confounding variables including age, sex, obesity and EDSS score, FIM total, motor and cognitive subscores were significantly associated with success (odds ratio [95% confidence interval] 1.06 [1.03-1.08], 1.05 [1.03-1.08], 1.21 [1.12-1.32], respectively).

CONCLUSIONS

FIM was an independent predictor of successful CIC training in pwMS. A 1-point increase in FIM was associated with 6% increased odds of successfully mastering the CIC technique. A widespread use of the FIM could help determine the different cognitive and/or motor objectives that need to be improved before CIC teaching.

Prevalence of comorbidities in multiple sclerosis patients with neurogenic bladder

AIMS

The aim of this study was to define the prevalence of comorbidities among multiple sclerosis patients with lower urinary tract symptoms.

METHODS

A retrospective study of data collected prospectively from January 2000 to March 2016 was carried out using a database. Comorbidities were divided into several classes according to the International Classification of Diseases (ICD-10).

RESULTS

One hundred and fifty-five patients were included. All had a neurogenic bladder with 150 (96%) overactive bladder. EDSS score was≥6 in 44 patients (28%). Comorbidities were present in 79 (50,9%) and the most frequent ones were cardiovascular (14,2%), endocrinological (10,3%), urological (8,4%), abdominal (7,7%). Overweight (BMI≥25) was observed in 63 (40%). A strict relationship was found for BMI and stress urinary incontinence (P<0.001) as well as voiding dysfunction (P=0.003) without significant association for BMI and overactive bladder.

CONCLUSION

Prevalence of comorbidities is important in MS (more than 50%). A significant association is found between overweight, stress urinary incontinence and voiding dysfunction. Knowledge of these comorbidities in MS is important since the presence of these urinary symptoms not related to neurogenic bladder must lead to a specific treatment.

Systematic review and meta-analysis efficacy and safety of immune checkpoint inhibitors in advanced melanoma patients with anti-PD-1 progression: a systematic review and meta-analysis

BACKGROUND

More than half of melanoma patients taking first-line anti-PD-1 therapy either express transient or no response at all. The efficacy and safety of secondary treatments for these patients are still not well established. Here, we evaluate the efficacy and safety of different melanoma FDA-approved ICI modalities used in post-anti-PD-1 refractory settings.

MATERIALS AND METHODS

We searched the PubMed database and the ASCO meetings library for studies on advanced melanoma patients with cancer progression on anti-PD-1 therapy and were then treated with ipilimumab, nivolumab/ipilimumab combination, or retreated with anti-PD-1. Primary and secondary endpoints were efficacy and toxicity, respectively. Pooled estimates for each treatment group were obtained using a random or fixed effects model according to detected heterogeneity.

RESULTS

Fourteen studies, of which 10 on ipilimumab, 2 on anti-PD-1 treatment, and 6 on combination therapies, were included, involving a total of 1460 patients. Twelve studies reported objective response rates (ORRs) and nine of them reported immune-related adverse events (irAEs). As for ORR, patients experienced a response that was inferior compared to the same therapy in treatment -naïve patients, with combination therapy having the best ORR of a pooled 23.08% (95% CI: 16.75% to 30.03%), followed by ipilimumab with a pooled ORR of 8.19% (95% CI: 5.78% to 10.92%). Survival data were also inferior in the ipilimumab cohort (mOS: 5.1 to 7.4 months) compared to ipilimumab in anti-PD-1 naive patients. As for grade 3/4 irAE occurrence, the ipilimumab cohort showed an estimate of 43.77% (95% CI 22.55% to 66.19%).

CONCLUSION

Our findings provide the best current evidence that patients who progress on anti-PD-1 can still respond to different ICI modalities (ipilimumab with or without nivolumab, and retreatment or continuation beyond progression with anti-PD-1) with tolerable grade 3/4 irAEs. However, more prospective clinical trials are needed to confirm these results.

Comparison of clinical and paraclinical characteristics of patients with urge, mixed, and passive fecal incontinence: a systematic literature review

PURPOSE

Two subgroups of fecal incontinence (FI) are described in literature and used in clinical practice. However, the pertinence of this classification of FI is still unknown as there are no clear established guidelines. To a better understanding, we performed a systematic review to characterize the different types of FI (active, passive, or mixed) on the basis of clinical presentation and complementary explorations.

METHODS

This systematic literature review was performed in reference to recommendations for systematic review using PRISMA guidelines without date restriction, until May 2020. This systematic review was performed without temporal limitation using MEDLINE-PubMed, Cochrane Library, and Google Scholar databases.

RESULTS

Six hundred nine unique citations were identified from all the databases combined. Of those, 21 studies met the inclusion criteria, with 8 retrospective observational studies and 13 prospective observational studies. There was a lack of homogeneity in definitions of passive and urge (active) FI among studies. Prevalence of passive and urge FI was respectively of 4.0-5.0 and 15.0-35.0%. Clinical characteristics, physical examination, and endoanal imaging were not evaluated in most studies. In anorectal manometry, maximal squeeze pressure was higher in passive FI subgroup in most studies and results regarding maximal resting pressure remain discordant. There seemed to be no difference regarding first sensation volume and maximal tolerable volume among subgroups. A few studies evaluated pudendal terminal nerve motor latency with no difference among subgroups.

CONCLUSION

There is a lack of well-conducted prospective studies comparing the different subtypes of FI with validated definitions in both clinical and paraclinical examinations.

Efficiency and satisfaction with telephone consultation of follow-up patients in neuro-urology: Experience of the COVID-19 pandemic

Aim

The COVID‐19 pandemic led to limit patients’ visits to the neuro‐urology department. Telemedicine was seen as a pragmatic solution to provide follow‐up care. This study aimed to assess the efficiency and satisfaction of a telephone consultation in neuro‐urology.

Methods

During the pandemic, the scheduled medical visits were converted into telephone consultation. For each teleconsultation, the physician assessed the efficiency and the patient‐rated global satisfaction of the teleconsultation. The physician and the patient assessed whether this teleconsultation replaced a physical visit.

Results

About 358 neurologic patients were included in the study. The mean efficiency of the telephone consultation was 9.3/10 (±1.5). The mean global satisfaction was 9.0/10 (±1.3). The majority of the patients (52.4%) would prefer a physical consultation. 90.2% might convert some clinic visits to teleconsultations in the future. No agreement was found between the patient and the physician when they were asked if the teleconsultation replaced the physical consultation initially scheduled (weight kappa = 0.02; 95% confidence interval = [−0.06 to 0.11]). Cognitive impairment, difficulty to obtain relevant information, and lack of physical examination were unfavorable to the efficiency of the teleconsultation. Cognitive impairment, embarrassing nature of the teleconsultation, and preference for a physical consultation were unfavorable to satisfaction of the patient.

Conclusion

Telemedicine in neuro‐urology was associated with a high satisfaction of the patients and was described as efficient by the physicians. Despite this, the majority of the patients reported a preference for physical consultation. The COVID‐19 pandemic might be an opportunity to refine our practices in neuro‐urology and to develop telemedicine.

[Neurological complications of coitus: Review of literature]

INTRODUCTION

Sexual activity is composed of different phases (excitation, plateau, resolution). Each phase is associated with cardiovascular, respiratory, muscular and hormonal modification which can have an influence on the nervous system. This impact has been studied many times in literature, but no study has synthetized the complications related to coitus or orgasm.

METHOD

Systematic review of literature on neurological complications, except headache, of coitus based on Medline and Embase.

RESULTS

We screened 1424 articles and selected 46 for this review. 7 (15 %) were clinical or epidemiologic studies, 6 (13 %) were reviews of literature and 33 (72 %) were cases or series of cases reports. 12 articles (26 %) talked about strokes, 10 (22 %) about subarachnoid hemorrhage, 9 (20 %) about reversible cerebral vasoconstriction syndrome. We found 3 (7 %) articles for each of the following complication: intraparenchymal, hematoma and epilepsy. Autonomic hypereflexia was treated in 3 articles (7 %). Only 1 article was included concerning ictus, spinal cord injury, neuralgia and cataplexia. These events can be considered as rare as emergencies related to sexual activity represent only 0.1 % of all emergencies and among these, 12 % are neurological. 31 of the reported cases concerned vascular events (stroke or hemorrhage) and 18 (58 %) of these patients had a patent malformation (aneurism, intracardiac shunt, foramen ovale).

CONCLUSION

This is one of the first review of literature trying to synthetise the neurological complications of coitus. Many articles exist in literature. It is necessary to prevent the occurrence of these complications in a population already at risk of neurological events.

Are falls in people with multiple sclerosis related to the severity of urinary disorders?

BACKGROUND

Lower urinary tract symptoms (LUTSs), especially overactive bladder, are frequent in people with multiple sclerosis (PwMS). Urinary urgency and urge urinary incontinence could lead to precipitation and thus could increase the risk of falling in these individuals.

OBJECTIVE

We aimed to assess the association between severity of LUTSs and risk of falling in PwMS.

METHODS

PwMS with LUTSs were recruited in a neuro-urology department. Participants were asked about the number of falls in the past 3 months and their circumstances. Severity of LUTSs was assessed by the Urinary Symptoms Profile (USP) score, and individuals were classified as with or without urinary incontinence.

RESULTS

This cross-sectional study included 154 patients (69% women); the mean (SD) age was 50.1 (11.5) years and median EDSS was 5 (interquartile range 3-6). Overall, 20 (13%) patients reported one fall during the past 3 months, and 43 (28%) reported at least 2 falls. Only 9 (6%) patients reported a fall on the way to the toilet, 6 during a urinary urgency. No link was found between falls and urinary incontinence (P=0.71), type or severity of urinary symptoms (overactivity, voiding dysfunction or stress incontinence, P>0.05). Falls on the way to the bathroom was associated with high USP score related to overactive bladder (P=0.03) and severe nocturia (>2 nocturnal micturitions) (P<0.01). Falling at night was also associated with severe nocturia (P<0.001).

CONCLUSIONS

The severity of LUTSs and presence of urinary incontinence do not appear related to the risk of falling in PwMS and urinary disorders but rather to the specific risk of falling on the way to the bathroom. Severe nocturia increases the risk of falling at night. Further studies are needed to assess the impact of LUTS treatment on the risk of falling. ClinicalTrials.gov (NCT04338646).

Fecal impaction is associated with postoperative urinary retention after hip fracture surgery

BACKGROUND

Postoperative urinary retention (POUR) is a common hip fracture (HF) complication. Although fecal impaction (FI) is one of the oft-cited causes of POUR in clinical practice, evidence regarding this association is scarce.

OBJECTIVE

The aim of this study was to determine whether FI was associated with POUR after HF surgery in older patients.

METHODS

All patients consecutively admitted after a HF surgery in a geriatric perioperative unit were included in this cross-sectional study. FI was systematically assessed by a digital rectal exam at admission and according to clinical suspicion during the hospital stay. The dependent variable was POUR, systematically screened according to the department protocol and defined as a bladder volume > 400 ml requiring catheterization. The association between FI and POUR was assessed by multivariable analysis.

RESULTS

A total of 256 patients were included (mean [SD] age 86 [6] years), 76% women): 108 (42%) presented FI and 63 (25%) POUR. The frequency of FI was higher with than without POUR (73% vs 32%, P<0.001). On multivariable analysis, after adjusting for age, sex, Cumulative Illness Rating Scale score and anticholinergic load, FI was the only factor independently associated with POUR (odds ratio 4.78 [95% confidence interval 2.44-9.71], P<0.001.

CONCLUSIONS

FI was the only independent factor associated with POUR after HF surgery in older adults. Further studies are needed to optimize perioperative geriatric care including FI and POUR assessment and management.

[Urethral reflexes: A review]

INTRODUCTION

The urethrosphincter complex is involved not only in maintaining urinary continence, particularly during effort, but also for the achievement of a complete and effective micturition. Indeed, the urethra is not a simple passive channel for the evacuation of urine from the bladder to the urethral meatus, since its resistive capacities and its possibilities of modulation of the micturition reflex depend on its reflex role either as a sensory afferent or as a neuro-muscular effector. It also participates in many genito-sexual and ano-rectal réflexes.

MATERIAL AND METHOD

This review of the literature describes the various reflexes of the urethra as a sensory stimulus or a neuromuscular effector. All articles referenced in this review were obtained from articles indexed on Pubmed-Medline, using the keywords: "urethral reflexes; "reflex bladder"; "urination reflex"; "intravaginal; vaginal"; "anorectal; sphincter"; "Storage and voiding"; "reflexes sneezing"; "cough reflex". Other articles were selected through references of the articles issued from the first research. Only articles in English and French have been selected. The articles concerned animal and human experiments.

RESULTS

Eight hundred and sixty-four referenced articles were founded and a total of 75 articles were included, describing the various reflexes mediated by the urethra acting as a sensory afferent or mechanical effector. We differentiated the known data in humans and animals.

CONCLUSION

The urethra is a complex anatomical structure ensuring, through numerous reflex mechanisms, urinary continence. Urethral resistances are modulated during efforts and depends on the bladder capacity and the intensity of the efforts. During micturition, the coordination between the bladder and the urethra is mediated by reflex pathways organized at the cerebral, spinal and lumbosacral levels. The modulation of the micturition in term of efficacy and velocity, is due in part, to the re-afferentation of the spinal reflex by continuous stimulus of the urethral canal. Many of these reflexes are imperfectly described. Finally, the urethra is implicated in reflex loops of anal continence and sexual functions.

Correction to: Association between nocturia and frailty among elderly males in a veterans administration population

In the original publication of the article, the author's name Jeffrey P. Weiss was misspelled as "Jeffry P. Weiss".

Association between nocturia and frailty among elderly males in a veterans administration population

BACKGROUND

The relationship between frailty and nocturnal voiding is poorly understood.

AIM

To characterize the association between frailty, as defined by a frailty index (FI) based upon the Canadian Study of Health and Aging (CSHA) criteria, and nocturia, defined by measures of nocturnal urine production.

METHODS

Real-world retrospective analysis of voiding diaries from elderly males with lower urinary tract symptoms (LUTS) at an outpatient urology clinic. Males ≥ 65 years with ≥ 2 nocturnal voids were included. A modified FI was calculated from the LUTS database, which captured 39 variables from the original CSHA FI. Patients were divided into 3 groups by modified FI: low (≤ 0.077) (n = 59), intermediate (> 0.077 and < 0.179) (n = 58), and high (≥ 0.179) (n = 41). Diary parameters were compared using the Kruskal-Wallis test and pairwise comparisons with the Wilcoxon rank-sum test and Bonferroni adjustment.

RESULTS

The high frailty group was characterized by higher nocturnal urine volume (NUV), maximum voided volume (MVV), nocturnal maximum voided volume (NMVV), and nocturnal urine production (NUP). The presence of comorbid diabetes mellitus did not explain this effect.

CONCLUSION

Elderly males seeking treatment for LUTS with a high frailty burden are disproportionately affected by excess nocturnal urine production. Future research on the mechanistic relationship between urine production and functional impairment is warranted.

Impact of food and drinks on urine production: A systematic review

CONTEXT

The impact of food and drinks on body fluid metabolism is of direct clinical relevance but current evidence remains fragmented.

AIM

Synthesise current evidence on the role of food and drinks in urine production.

METHODS

Systematic review as per PRISMA guidelines using MEDLINE and EMBASE databases (completed October 2019). Studies reporting on the effect of food, food constituents, and drinks on urine production were included. Two authors performed an independent extraction of relevant articles using predetermined data sets and completed quality-of-study indicators.

RESULTS

A total of 49 studies were included, of which 21 enroled human subjects, and 28 were clinically relevant animal studies (all of which utilised rodent models). The included studies were determined to be of variable quality. High dietary sodium, as well as wine, spirits, high-caffeine coffee, and caffeinated energy drinks, increased urine production in human studies. Decreased urine production was associated with low dietary sodium and consumption of milk, orange juice, and high-salt/high-sugar drinks. In animal models, a variety of fruits, vegetables, herbs, spices, and honey were associated with increased urine production.

CONCLUSION

Current evidence suggests that although several types of food and drinks may impact body fluid metabolism, the quality of the data is variable. Urine production appears to be influenced by multiple factors including composition (ie, moisture, macronutrients, and electrolytes), metabolite load, and the presence of specific diuresis-promoting substances (eg, caffeine, alcohol) and other bioactive phytochemicals. Future research is needed to support current evidence and the physiologic mechanisms underlying these findings.

Multifocal adult rhabdomyoma of the head and neck: case report and systematic review of the literature

Adult-type rhabdomyoma (ARM) is the most frequent extracardiac subtype of rhabdomyoma. In very rare instances ARM presents as multiple cervical lesions, an entity known as multifocal ARM. The aim of this study was to review the clinical characteristics and the best therapeutic options for multifocal ARM. The case of a 73-year-old patient recently diagnosed with multifocal ARM and managed in our institution is reported, followed by a systematic review of the literature. The review was conducted using the PubMed, Scopus, and Google Scholar databases, according to the PRISMA guidelines. All case reports and case series related to multifocal ARM written in English or French were included. A total of 29 cases were included in the qualitative analysis. Mean age at presentation was 65.0 years and the male to female ratio was 13.5:1. Dysphagia was the most common presenting symptom. ARM was most frequently found in the submandibular spaces. In conclusion, multifocal ARM are benign tumours with a predilection for the head and neck region. They become symptomatic with gradual compression of the adjacent structures. No cases of malignant transformation were reported in the literature. We suggest a 'watchful wait' approach for small asymptomatic tumours and excision of large symptomatic ones.

Nocturia in patients with cognitive dysfunction: a systematic review of the literature

Background

The objective of this study is to evaluate current literature on the association between cognitive dysfunction and nocturia.

Methods

A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was conducted through MEDLINE, EMBASE and COCHRANE databases and completed in November 2019. Randomized and non-randomized studies were included if they assessed the association between cognitive dysfunction and nocturia in older participants with or without neurological diseases. The quality of included studies was evaluated using the Risk of Bias Assessment tool for Non-randomized Studies (RoBANS).

Results

A total of 8 cross-sectional studies conducted in older patient populations met the criteria for inclusion. A statistically significant association was identified in 6 studies on univariate analysis, which persisted in 2 studies after controlling for confounding factors. The association between cognitive dysfunction and nocturia was positive for all 6 significant analyses. The overall risk of bias was unclear.

Conclusion

A significant positive association between cognitive dysfunction and nocturia was identified. However, research has been limited to cross-sectional studies, which precludes identification of causality between cognitive dysfunction and nocturia. Heightened awareness of the complex interplay between cognition and nocturia would allow professionals involved in the care of cognitively impaired patients with concomitant nocturia to more effectively manage these symptoms.

Development of a flowchart reflecting the current attitude and approach towards idiopathic overactive bladder treatment in Belgium: A Delphi study

AIMS

Idiopathic overactive bladder syndrome (iOAB) is a prevalent condition in urological practice. The variability in management between specialists and between centers remains high. Even existing guidelines contain inconsistencies. We aimed to develop a treatment algorithm for iOAB for use in daily clinical practice.

METHODS

From October 2018 till November 2019, a Delphi study was conducted to obtain expert consensus on the management of iOAB. Members from the Belgian Working Group of Functional Urology were asked to rate online statements, based on gaps and variabilities between the American Urology Association (AUA), European Association of Urology (EAU) and International Consultation on Incontinence (ICI) guidelines on iOAB. The consensus was reached if ≥75% of the panel agreed on the level of appropriateness. Two Delphi rounds and an open discussion session were held.

RESULTS

Twenty out of 49 members completed the first round and 18 completed the second round. The consensus was reached on 44/143 statements and 15/56 statements in the first and second round, respectively. The consensus was reached on criteria by which to phenotype OAB patients, the terminology relating to the first-, second- and third-line treatment, the duration of therapies, the chronological order, and the choice between therapies. No consensus was reached on the role of percutaneous tibial nerve stimulation (PTNS) in the treatment algorithm.

CONCLUSIONS

A flowchart reflecting the current attitude and approach of a Delphi expert panel towards the treatment of iOAB was developed. We propose its use in daily clinical practice to increase the standardization of OAB treatment.

Durvalumab with or without tremelimumab in patients with recurrent or metastatic head and neck squamous cell carcinoma: EAGLE, a randomized, open-label phase III study

BACKGROUND

Targeting the programmed cell death protein 1 (PD-1)/programmed cell death ligand 1 (PD-L1) axis has demonstrated clinical benefit in recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC). Combining immunotherapies targeting PD-L1 and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) has shown evidence of additive activity in several tumor types. This phase III study evaluated the efficacy of durvalumab (an anti-PD-L1 monoclonal antibody) or durvalumab plus tremelimumab (an anti-CTLA-4 monoclonal antibody) versus standard of care (SoC) in R/M HNSCC patients.

PATIENTS AND METHODS

Patients were randomly assigned to receive 1 : 1 : 1 durvalumab (10 mg/kg every 2 weeks [q2w]), durvalumab plus tremelimumab (durvalumab 20 mg/kg q4w plus tremelimumab 1 mg/kg q4w × 4, then durvalumab 10 mg/kg q2w), or SoC (cetuximab, a taxane, methotrexate, or a fluoropyrimidine). The primary end points were overall survival (OS) for durvalumab versus SoC, and OS for durvalumab plus tremelimumab versus SoC. Secondary end points included progression-free survival (PFS), objective response rate, and duration of response.

RESULTS

Patients were randomly assigned to receive durvalumab (n = 240), durvalumab plus tremelimumab (n = 247), or SoC (n = 249). No statistically significant improvements in OS were observed for durvalumab versus SoC [hazard ratio (HR): 0.88; 95% confidence interval (CI): 0.72-1.08; P = 0.20] or durvalumab plus tremelimumab versus SoC (HR: 1.04; 95% CI: 0.85-1.26; P = 0.76). The 12-month survival rates (95% CI) were 37.0% (30.9-43.1), 30.4% (24.7-36.3), and 30.5% (24.7-36.4) for durvalumab, durvalumab plus tremelimumab, and SoC, respectively. Treatment-related adverse events (trAEs) were consistent with previous reports. The most common trAEs (any grade) were hypothyroidism for durvalumab and durvalumab plus tremelimumab (11.4% and 12.2%, respectively), and anemia (17.5%) for SoC. Grade ≥3 trAE rates were 10.1%, 16.3%, and 24.2% for durvalumab, durvalumab plus tremelimumab, and SoC, respectively.

CONCLUSION

There were no statistically significant differences in OS for durvalumab or durvalumab plus tremelimumab versus SoC. However, higher survival rates at 12 to 24 months and response rates demonstrate clinical activity for durvalumab.
