Approach and management to patients with neurological disorders reporting sexual dysfunction

Research progress and prospects of benefit-risk assessment methods for umbilical cord mesenchymal stem cell transplantation in the clinical treatment of spinal cord injury

Over the past decade, we have witnessed the development of cell transplantation as a new strategy for repairing spinal cord injury (SCI). However, due to the complexity of the central nervous system (CNS), achieving successful clinical translation remains a significant challenge. Human umbilical cord mesenchymal stem cells (hUMSCs) possess distinct advantages, such as easy collection, lack of ethical concerns, high self-renewal ability, multilineage differentiation potential, and immunomodulatory properties. hUMSCs are promising for regenerating the injured spinal cord to a significant extent. At the same time, for advancing SCI treatment, the appropriate benefit and risk evaluation methods play a pivotal role in determining the clinical applicability of treatment plans. Hence, this study discusses the advantages and risks of hUMSCs in SCI treatment across four dimensions-comprehensive evaluation of motor and sensory function, imaging, electrophysiology, and autonomic nervous system (ANS) function-aiming to improve the rationality of relevant clinical research and the feasibility of clinical translation.

Sexual dysfunction and commonly used drugs in neurology

Sexual dysfunction is common in men and women with neurological diseases. Medications used in neurology can cause sexual dysfunction independently of the disease process and this may adversely affect patients' quality of life. This review focuses on medications commonly prescribed to neurological patients that may contribute to altered sexual function, and discusses how they may differ in men and women.

Experience of adapted cognitive behaviour therapy to address sexuality problems after traumatic brain injury: A qualitative study

Although sexuality has been shown to be negatively impacted in up to half of individuals who sustain traumatic brain injury (TBI), few studies have sought to evaluate the efficacy of targeted interventions. Gaining insight into the participant experience of undergoing treatment for post-TBI sexuality changes is a crucial aspect of intervention evaluation. This study aimed to investigate participants with TBI experience of undergoing eight sessions of a novel CBT intervention designed to help both couples and singles improve sexual wellbeing after TBI. Eight participants (50% male) with moderate-severe TBI, and a mean age of 46.38-years (SD = 13.54), completed a qualitative interview. A six-phase reflexive thematic analysis approach was used. Despite variability in participant characteristics, the findings suggested that participants with TBI experience reflected that of a positive treatment journey characterized by high levels of enjoyment and satisfaction. Key themes identified included contextual factors that preceded treatment, factors that facilitated treatment engagement, outcomes derived from the treatment experience, and feedback provided on reflection. The results not only provide an enriched understanding of the client experience of the intervention but provide corroborating preliminary evidence of efficacy for this novel CBT intervention in addressing complex and persistent sexuality problems after TBI.

Efficacy of Neuromodulation Interventions for the Treatment of Sexual Dysfunction: A Systematic Review

OBJECTIVES

The primary aim of this review was to analyze the literature for the efficacy of neuromodulation interventions in treating both male and female sexual dysfunction.

MATERIALS AND METHODS

Studies were identified from PubMed, Scopus, PsychINFO, CINAHL, and Cochrane. Results were synthesized qualitatively without pooling owing to the heterogeneous nature of outcome assessments.

RESULTS

Overall findings from studies generally supported that neuromodulation interventions were associated with improvement in sexual function. Specific domains that improved in male patients included erectile function, desire, and satisfaction, whereas desire, arousal, orgasm, lubrication, quality of "sex life," intercourse capability, and dyspareunia improved in female patients. Male ejaculation, orgasm, and intercourse capability were the only domains that continued to decline after the use of neuromodulation interventions, although this was only reported in one study.

CONCLUSION

Our review suggests that there may be promise and potential utility of neuromodulation in improving sexual dysfunction; however, further research is needed.

Expectations about the management of sexual dysfunction in women with multiple sclerosis and association with clinical characteristics

BACKGROUND

Sexual dysfunction (SD) is common in women with multiple sclerosis (MS) and affects their quality of life.

OBJECTIVES

The primary aim is to assess their expectations concerning SD management. The secondary aim is to identify if expectations were associated with specific patient's characteristics.

METHODS

All women with MS who underwent a urodynamic assessment in a neuro-urology clinic and had a standardized assessment of SD expectations between June 2020 and November 2022 were retrospectively screened. Demographic data and assessment of bladder, bowel, and sexual dysfunctions with validated questionnaires were collected.

RESULTS

One hundred and sixty-seven patients were included in the study (mean age 47.9 ± 12.5 years). Expectations on SD information or management were reported by 112 (67.1%) patients. Interest in SD information and management was less frequent after menopause (56% vs 80%, p = 0.004), and in those with EDSS>6 (49% vs 74%, p = 0.03) and progressive type of MS (54% vs 71% p = 0.003). In multivariate analysis, the progressive type of MS was the only criterion related to a lack of interest (OR=2.9 IC95% [1.09; 7.72]).

CONCLUSIONS

Women with MS have high expectations on treatment and information about SD. A systematic screening of SD expectations should be encouraged.

Prediction of Lower Urinary Tract, Sexual, and Bowel Function, and Autonomic Dysreflexia after Spinal Cord Injury

Spinal cord injury (SCI) produces damage to the somatic and autonomic pathways that regulate lower urinary tract, sexual, and bowel function, and increases the risk of autonomic dysreflexia. The recovery of these functions has a high impact on health, functioning, and quality of life and is set as the utmost priority by patients. The application of reliable models to predict lower urinary tract, sexual, and bowel function, and autonomic dysreflexia is important for guiding counseling, rehabilitation, and social reintegration. Moreover, a reliable prediction is essential for designing future clinical trials to optimize patients' allocation to different treatment groups. To date, reliable and simple algorithms are available to predict lower urinary tract and bowel outcomes after traumatic and ischemic SCI. Previous studies identified a few risk factors to develop autonomic dysreflexia, albeit a model for prediction still lacks. On the other hand, there is an urgent need for a model to predict the evolution of sexual function. The aim of this review is to examine the available knowledge and models for the prediction of lower urinary tract, sexual, and bowel function, and autonomic dysreflexia after SCI, and critically discuss the research priorities in these fields.

Advanced hydrogels: New expectation for the repair of organic erectile dysfunction

Organic erectile dysfunction (ED) is a type of sexual disorder in men that is usually associated with illness, surgical injury, normal aging and has a high incidence across the globe. And the essence of penile erection is a neurovascular event regulated by a combination of factors. Nerve and vascular injury are the main causes of erectile dysfunction. Currently, the main treatment options for ED include phosphodiesterase type 5 inhibitors (PDE5Is), intracorporeal injections and vacuum erection devices (VEDs), which are ineffective. Therefore, it is essential to find an emerging, non-invasive and effective treatment for ED. The histopathological damage causing ED can be improved or even reversed with hydrogels, in contrast to current therapies. Hydrogels have many advantages, they can be synthesized from various raw materials with different properties, possess a definite composition, and have good biocompatibility and biodegradability. These advantages make hydrogels an effective drug carrier. In this review, we began with an overview of the underlying mechanisms of organic erectile dysfunction, discussed the dilemmas of existing treatments for ED, and described the unique advantages of hydrogel over other approaches. Then emphasizing the progress of research on hydrogels in the treatment of ED.

The outcomes of penile prosthesis in neurologic patients: a multicentric retrospective series

Introduction

Neurological disease is a known entity for causing erectile dysfunction (ED). Pharmacological therapies are not always effective these patients - penile prosthesis implant (PPI) is an established surgical treatment option. For a variety of reasons, neurological patients may experience differing outcomes of PPI compared to those whose ED arises from other causes. We investigated outcomes of PPI in neurological patients using the Italian multi-institutional national registry of penile prostheses [Italian Nationwide Systematic Inventarization of Surgical Treatment for ED (INSIST-ED)].

Methods

Patients undergoing PPI were investigated via the INSIST-ED registry, from 2014 to 2021. Data were prospectively recorded by 45 surgeons on a dedicated website (www.registro.andrologiaitaliana.it) and reviewed by a data manager. We subselected patients with neurological disease undergoing PPI for ED, and these patients were reviewed at 3, 6, and 12 months, and annually thereafter. Postoperative complications and functional outcomes were evaluated through validated questionnaires [International Index of Erectile Function-5 (IIEF-5), Sexual Encounter Profile 2-3, and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS)]. A nonvalidated questionnaire was administered to assess patient satisfaction.

Results

A total of 33 patients were included with a median age of 49 [interquartile range (IQR) 41-55]. Median follow-up was 83 months (IQR 67-99.5). A penoscrotal approach for PPI was performed in most cases (90.9%), while infrapubic was used in three cases (9.1%). Inflatable and malleable devices were implanted in 30 (90.9%) and 3 cases (9.1%), respectively. Intraoperative complications occurred in one case (3%). Early postoperative complications (<90 days) were observed in three cases (9.1%): two wound dehiscence (Clavien-Dindo G1 and G3a respectively) and one device infection requiring prosthesis explant (Clavien-Dindo G3a). Mechanical failures of inflatable devices were not observed during the follow-up period. Median IIEF-5 before surgery was 8 (IQR 7-9). At the latest follow-up, IIEF-5 was 22 (IQR 19-23.5), and median EDITS was 79 (IQR 64-88). A total of 28 patients (84.8%) self-reported to be fully satisfied with the PPI.

Conclusion

Although PPI in the neurological population has been historically considered to be at increased risk, in our study, PPI complications and infections rates in this cohort did not differ from general population.

Urogenital dysfunction following neurotrauma

PURPOSE OF REVIEW

Trauma affecting the nervous system can have widespread consequences, depending on the location and severity of injury. The sensorimotor and cognitive deficits due to neurotrauma have been studied extensively. Although the overall mortality due to neurotrauma has reduced, the disability and morbidity due to neurotrauma has not significantly reduced and focus on urogenital disturbances in these patients has been limited. This article reviews the limited evidence and scientific literature on this topic.

RECENT FINDINGS

Lower urinary tract symptoms are commonly reported in patients with neurotrauma, both acutely and over the long term. Multiple medical and surgical approaches are available for managing bladder dysfunction in these patients. Sexual dysfunction and changes in sexual behaviour are reported by patients with neurotrauma and are usually multifactorial. Treatment options for sexual dysfunction are available and their management requires a holistic approach.

SUMMARY

Urogenital dysfunction contributes significantly to the overall functional outcome and impaired quality of life in patients with neurotrauma. A better understanding of the mechanisms behind the urogenital abnormalities is needed for efficient management and treatment.

Evaluating a Novel Treatment Adapting a Cognitive Behaviour Therapy Approach for Sexuality Problems after Traumatic Brain Injury: A Single Case Design with Nonconcurrent Multiple Baselines

There has been little progress in development of evidence-based interventions to improve sexuality outcomes for individuals with traumatic brain injury (TBI). This study aimed to evaluate the preliminary efficacy of an individualised intervention using a cognitive behaviour therapy (CBT) framework to treat sexuality problems after TBI. A nonconcurrent multiple baseline single-case design with 8-week follow-up and randomisation to multiple baseline lengths (3, 4, or 6 weeks) was repeated across nine participants (five female) with complicated mild–severe TBI (mean age = 46.44 years (SD = 12.67), mean post-traumatic amnesia = 29.14 days (SD = 29.76), mean time post-injury = 6.56 years (median = 2.50 years, SD = 10.11)). Treatment comprised eight weekly, individual sessions, combining behavioural, cognitive, and educational strategies to address diverse sexuality problems. Clinical psychologists adopted a flexible, patient-centred, and goal-orientated approach whilst following a treatment guide and accommodating TBI-related impairments. Target behaviour was subjective ratings of satisfaction with sexuality, measured three times weekly. Secondary outcomes included measures of sexuality, mood, self-esteem, and participation. Goal attainment scaling (GAS) was used to measure personally meaningful goals. Preliminary support was shown for intervention effectiveness, with most cases demonstrating sustained improvements in subjective sexuality satisfaction and GAS goal attainment. Based on the current findings, larger clinical trials are warranted.
