The Role of Vibrators in Women's Pelvic Health: An Alluring Tool to Improve Physical, Sexual, and Mental Health.

INTRODUCTION AND HYPOTHESIS: In limited studies vibrators have been shown to improve sexual function and pelvic floor health; however, there are even fewer studies on the effect of vibrator use on overall genitourinary and mental health. To investigate the effect of regular vibrator use on sexual, genitourinary, and mental health in addition to quality of life. METHODS: We performed a prospective pilot study of women aged 18 to 80 years recruited from a urogynecology clinic. Study participants were instructed to use a vibrator according to the protocol. Sexual function, pelvic floor function, mental health, and pelvic examination were assessed at the initial visit and at 3 months' follow-up using validated questionnaires. RESULTS: Of the 79 participants enrolled in the study, 53 women (66%) completed the study. The mean age of the participants was 54.7 years (range 19-80 years), and the majority of participants were white (n = 59, 74.7%), post-menopausal (n = 48, 60.8%), and not receiving systemic (n = 63, 79.7%) or local (n = 63, 79.7%) hormone therapy. Sexual function significantly improved over time (p = 0.002), whereas the rate of bothersome pelvic organ prolapse symptoms and pain scores significantly decreased (p = 0.034 and 0.0008 respectively). Rates of urge urinary incontinence decreased although this was not statistically significant (p = 0.059). There was a significant improvement in the gross appearance of lichen sclerosus lesions (p = 0.025) and in the severity of vaginal atrophy (p = 0.018). Rates of depression were significantly decreased (p = 0.011). CONCLUSIONS: Vibrator use was associated with improved sexual, genitourinary, and mental health.

A Pilot Study of the Effect of Transcutaneous Spinal Cord Stimulation on Micturition-Related Brain Activity and Lower Urinary Tract Symptoms After Stroke.

PURPOSE: Transcutaneous spinal cord stimulation (TSCS) is a novel neuromodulation modality developed to promote functional restoration in patients with neurological injury or disease. Previous pilot data suggest that lower urinary tract dysfunction (LUTD) due to stroke may be partially alleviated by TSCS. In this study, we examine the mechanism of this effect by evaluating bladder-related brain activity in patients before and after TSCS therapy and comparing it to healthy volunteers. MATERIALS AND METHODS: Patients who developed storage LUTD after a stroke and healthy volunteers without LUTD were recruited. Patients and healthy volunteers underwent simultaneous urodynamics and functional MRI. Patients then completed 24 biweekly sessions of TSCS and underwent another simultaneous urodynamics-functional MRI study. Clinical outcomes were assessed using validated questionnaires and voiding diary. RESULTS: Fifteen patients and 16 healthy volunteers completed the study. Following TSCS, patients exhibited increased blood-oxygen-level-dependent activity in areas including periaqueductal grey, the insula, the lateral prefrontal cortex, and motor cortex. Prior to TSCS therapy, healthy controls exhibited higher blood-oxygen-level-dependent activity in 17 regions, including multiple regions in the prefrontal cortex and basal ganglia. These differences were attenuated after TSCS with no frontal brain differences remaining between healthy volunteers and stroke participants who completed therapy. Neuroimaging changes were complemented by clinically significant improvements in questionnaire scores and voiding diary parameters. CONCLUSIONS: TSCS therapy modulated bladder-related brain activity, reducing differences between healthy volunteers and stroke patients with LUTD. These changes, alongside improved clinical outcomes, suggest TSCS as a promising approach for LUTD management.

Gender disparities among publications within international sexual medicine urology journals and the impact of blinding in the review process.

BACKGROUND: While female urologists are known to publish at less frequency than their male peers, The Journal of Sexual Medicine was reported to have among the highest growth in female authorship from 2002 to 2020 in urology journals. AIM: We sought to assess the frequency of female authorship in sexual medicine journals worldwide and the factors that affect this, including the blinded/unblinded review process. METHODS: Eleven sexual medicine journals were assessed for geographic location, peer review method, and SCImago Journal Rank citation index (a metric of citation frequency and prestige). Journals were grouped into top, middle, and bottom quartiles based on metric score. Web of Science was used to access the publications' first, second, last, and corresponding authors from the past 5 years. An internet search or Gender-API.com was used to determine the gender identities of authors. Univariate and multivariable logistic regression models were performed. OUTCOMES: Outcomes included the likelihood of female authorship (first, second, last, and corresponding) based on journal location and ranking, the clustering of female authors, the journal's peer review process, and the frequency of female editorial board members. RESULTS: Overall, 8938 publications were identified. Women represented 30.7%, 31.3%, 21.3%, and 18.7% of the first, second, last, and corresponding authors, respectively; gender was unable to be assessed for 2.6%, 17.2%, 7.3%, and 2.7%. On univariate analysis, journals from North America, in the top quartile, and with a double-blind review process were more likely to have female authors (P < .001). On multivariate analysis, articles were more likely to have a female first author if they had a double-blind peer review process (odds ratio [OR], 1.20; 95% CI, 1.02-1.40), a female second author (OR, 2.54; 95% CI, 2.26-2.85), or a female corresponding author (OR, 7.80; 95% CI, 6.69-9.10). CLINICAL IMPLICATIONS: Gender-concordant mentoring and universal double-blind manuscript review processes may minimize the impact of gender bias and increase female authorship rates, in turn producing more diverse research. STRENGTHS AND LIMITATIONS: This is the first study assessing female authorship in sexual medicine journals. Limitations include not assessing every author listed on articles and being unable to determine gender identities for some authors. CONCLUSION: Female authorship rates are higher than reported rates of practicing female urologists but still lower than their male peers. Female authors were more likely to be published in journals with double-blind peer review processes and when publishing with additional female authors.

Resilience as an Independent Predictor of Bowel Related Quality of Life After Spinal Cord Injury.

Bowel dysfunction remains a prominent priority in the rehabilitation of patients with spinal cord injuries (SCIs). However, our understanding of the factors that influence bowel-related quality of life (QoL) in this population remains limited. This study aimed to investigate the potential role of resilience, defined as an individual's capacity to cope with and adapt to adversity, as a predictor of bowel-related QoL among the patients with SCI. A cohort of adult patients with SCI who received bowel and bladder care at an outpatient clinic within a large rehabilitation hospital was identified through a prospectively collected database. Resilience was measured using the Spinal Cord Injury-Quality of Life (SCI-QOL) Resilience Short Form, whereas bowel QoL was assessed using the Irritable Bowel Syndrome-Quality of Life (IBS-QoL) questionnaire. Univariate and multivariate regression analyses were employed to identify predictors of bowel-related QoL. The examined variables included age, gender, level and completeness of injury, time since injury, hand function, resilience, and the severity of bowel dysfunction as measured using the Neurogenic Bowel Dysfunction Score (NBDS). A total of 73 patients participated in this study, with a mean age of 44.01 ± 13.43 years and comprising mostly men (n = 57, 78%). The results revealed a significant correlation between resilience scores and the total score of IBS-QoL (ρ = -0.47, p < 0.0001). The multivariate analysis demonstrated that both resilience and the severity of bowel dysfunction were significant independent predictors of bowel-related QoL, with resilience demonstrating a stronger association. Overall, this study elucidates the importance of resilience in shaping patients' perceptions of their bowel health within the SCI population. In addition to the more expected determinants of bowel-related QoL, such as the severity of bowel dysfunction, resilience emerged as a notable factor. Accordingly, integrating interventions that enhance resilience within bowel rehabilitation programs may yield improvements in patients' perceived bowel health beyond the benefits achievable through bowel function enhancement alone.

Content, face, and construct validity of the Irritable Bowel Syndrome Quality of Life (IBS-QOL) as a measure of bowel-related quality of life in spinal cord injury.

INTRODUCTION: Neurogenic bowel dysfunction is commonly encountered after a spinal cord injury (SCI), leading to a tremendous impact on quality of life (QOL). The neurogenic bowel dysfunction score (NBDS) is commonly used to measure the severity of bowel dysfunction and predict QOL. However, there is no comprehensive instrument to assess bowel-specific QOL for SCI patients. Instead, the Irritable Bowel Syndrome-Quality of Life (IBS-QOL) questionnaire evaluates the impact of bowel dysfunction on several aspects of QOL, although this questionnaire has not been validated for the SCI population. Motivated by the compelling need of instruments to accurately evaluate the QOL in patients who develope NBD after SCI, we aimed to assess the construct, content, and face validity of IBS-QOL in this population. METHODS: Adult SCI patients with at least 3 months after their injury were recruited from the outpatient clinic of a national rehabilitation hospital. Patients completed the NBDS and IBS-QOL via telephone interview or paper survey in the clinic. Content and face validity were assessed via interviews with professionals with expertise in providing chronic care for SCI, as well as a subgroup of patients. Construct validity was assessed using the hypotheses testing method. Internal consistency was assessed using Cronbach's ⍺. Factor analysis was performed to assess the dimensionality of the IBS-QOL in the SCI population. RESULTS: A total of 106 patients with a median age of 45.5 years (interquartile range: 21-79) participated in the study. The majority of the sample were men (n = 82, 77%) and had endured thoracolumbar injuries (n = 74, 71.2%). Twelve patients (seven English- and five Spanish speakers) and six professionals took part in content/face validation interviews. The median IBS-QOL total score was 15.91/100 (interquartile range: 4.55-33.14). IBS-QOL differentiated the subgroups of patients with severe bowel symptoms in terms of uneasiness, sweating, or headaches during bowel emptying (p = 0.0003), time spent on bowel emptying (p = 0.0065), flatus incontinence (p = 0.0076), and overall satisfaction with bowel function (p < 0.001), demonstrating its adequate construct validity. Interviews with the patients and professionals supported the comprehensiveness, comprehensibility, and relevance of IBS-QOL for assessment of bowel-related QOL in the SCI population. Item-level analysis of professional responses showed that 97% of questions were relevant to the construct and population of interest. Internal consistency analysis yielded a Cronbach's ⍺ of 0.9684. Exploratory factor analysis yielded six underlying factors which cumulatively accounted for 72.21% of the total variance, reflecting the dimensionality of bowel-related QOL in SCI population. DISCUSSION: IBS-QOL questionnaire is a comprehensive measure of bowel-related QOL which encompasses the concerns of SCI patients. Our findings support the content, face and construct validity of IBS-QOL as a measure of bowel-related QOL in SCI. Further studies are warranted to assess the reliability and responsiveness of IBS-QOL, and to evaluate its performance across different patient populations.

Consistency of endometrial receptivity array and histologic dating of spatially distinct endometrial samplings: a prospective, blinded study.

Objective: To compare the consistency of endometrial receptivity array (ERA) and histologic dating among 3 spatially distinct endometrial samples obtained during a cycle of exogenous estrogen and progesterone. Design: Prospective blinded study. Setting: University practice. Patients: Twelve patients undergoing a mock frozen embryo transfer cycle. Intervention: Endometrial biopsy was performed in a manner that provided a spatially organized endometrial specimen, corresponding to the fundus, middle, and lower segment. Each of these 3 sections was further divided into immediately adjacent specimens for ERA and histology. Main Outcome Measure: Consistency of the ERA and histology results among fundal, mid, and lower endometrial biopsy specimens. Results: The ERA showed variability in outcome among different patients but dated all specimens originating from the same patient identically. Histologic dating showed variability between patients as well as between different locations within the uterus. When comparing average dating results for each patient, we saw a positive correlation between histologic and ERA dating (Spearman Rho = 0.45); however, this did not reach statistical significance. The ERA results from upper, mid, and lower uterine biopsy specimens were identical for each autologous biopsy, whereas histologic dating showed variability with an average standard deviation of 0.71 days. Conclusions: The increased heterogeneity of histologic dating is likely to be attributed to the subjectivity of the test. Furthermore, we did not observe a consistent lag or advancement in histologic or ERA dating between the fundal or lower uterine biopsies. Overall, clinicians should be reassured that endometrial tissue will return consistent ERA results independent of the location within the uterus in which it was obtained.

Epithelioid Hemangioma of the Glans Penis in an Adolescent Male: A Case Report.

Epithelioid hemangioma is a rare vascular lesion consisting of capillaries and inflammatory infiltrate containing lymphocytes, and mast cells. The presentation of penile epithelioid hemangioma has been previously described in the adult literature; however, few cases have been reported in the pediatric population. Herein we present a case of penile epithelioid hemangioma in a 15-year-old patient with regrowth following surgical resection, requiring more extensive surgical excision with urethral reconstruction. This rare case highlights the importance of a proper diagnosis and complete microscopic removal.

Health Care Economic Burden of Treatment and Rehabilitation for Neurogenic Lower Urinary Tract Dysfunction: A Systematic Review.

PURPOSE: The clinical, social, and economic impacts of neurogenic lower urinary tract dysfunction (NLUTD) on individuals and health care systems are thought to be immense, yet the true costs of care are unknown. The aims of this study are to illuminate the global costs related to the current state of care for NLUTD. MATERIALS AND METHODS: A systematic review of the literature was performed using MEDLINE, the National Health Service Economic Evaluation Database, and the Cochrane Specialized Urology and Incontinence Registers. Studies reporting the health care costs of NLUTD were identified. All steps of the review were performed by 2 independent reviewers. Costs were converted to 2022 U.S. dollars and reported for different categories of services. RESULTS: A total of 13 studies were included in the final review (12 from high-income economy, and 1 from an upper-middle-income economy). Routine maintenance care varied notably across studies in terms of included services. Annual supportive costs ranged from $2,039.69 to $12,219.07 with 1 study estimating lifetime costs of $112,774 when complications were considered. There were limited data on the costs of care from the patient's perspective. However, catheters and absorbent aids were estimated to be among the costliest categories of expenditure during routine care. More invasive and reconstructive treatments were associated with significant costs, ranging between $18,057 and $55,873. CONCLUSIONS: NLUTD incurs a variety of health care expenditures ranging from incontinence supplies to hospitalizations for management of complications and leads to a significant burden for health care systems over the patient's lifetime. Approaches to NLUTD that focus on functional rehabilitation and restoration, rather than on management of complications, may prove to be a less costly and more effective alternative.

Gender Disparities Among Editorial Boards of International Urology Journals.

BACKGROUND: Gender composition among surgical academic leadership, including academic medical journals, disproportionately favors men and may inadvertently introduce a bias. An understanding of the factors associated with gender representation among urologic journals may aid in prioritizing an equitable balance. OBJECTIVE: To evaluate female representation on editorial boards of pre-eminent international urologic journals. DESIGN, SETTING, AND PARTICIPANTS: The names and position descriptions of urologic journal leadership appointees were collected in October 2021. Gender was assessed using gender-api.com or through personal title, as available. Journal characteristics were summarized using SCImago, a bibliometric indicator database extracted from Scopus journal data. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A multivariate logistic regression analysis was performed to describe associations between SCImago Journal Rank (SJR) quartile and geographic region with female gender representation. Quartile 1 (Q1) was considered the top quartile and Q4 the bottom quartile concordant with journal impact factor. RESULTS AND LIMITATIONS: A total of 105 urology-focused journals were identified with 5989 total editorial board members, including 877 (14.6%) female, 5112 (85.4%) male, and two nonbinary persons. Female representation differed significantly by journal leadership position, SJR quartile, and geographic region. On the multivariate analysis of overall female representation, Q1 journals had higher odds of female representation than Q2 and Q3 journals, and had no significant difference from Q4 journals. Additionally, compared with Western Europe, North American journals had 78% higher odds while Asiatic journals had 50% lower odds of female representation. This study is limited by the inability to account for outside factors that lead to invitation or acceptance of journal leadership positions. CONCLUSIONS: Contemporary female leadership at urology journals is about six times less common than male leadership across all journals, although trends in their proportion were noted when assessed by journal quartile and region. Addressing this gender imbalance represents an important step toward achieving gender equity in the field of urology. PATIENT SUMMARY: In this study, we looked at the gender balance of academic journal leaders who serve as gatekeepers for sharing urologic research with the public. We found that the most prestigious journals and those in western countries tended to have the highest female representation. We hope that these findings help the academic community recognize and improve gender representation.

Noninvasive spinal neuromodulation mitigates symptoms of idiopathic overactive bladder.

BACKGROUND: Overactive bladder (OAB) affects 12 to 30% of the world's population. The accompanying urinary urgency, frequency and incontinence can have a profound effect on quality of life, leading to depression, social isolation, avoidance of sexual activity and loss of productivity. Conservative measures such as lifestyle modification and pelvic floor physical therapy are the first line of treatment for overactive bladder. Patients who fail these may go on to take medications, undergo neuromodulation or receive injection of botulinum toxin into the bladder wall. While effective, medications have side effects and suffer from poor adherence. Neuromodulation and botulinum toxin injection are also effective but are invasive and not acceptable to some patients. METHODS: We have developed a novel transcutaneous spinal cord neuromodulator (SCONE™,) that delivers multifrequency electrical stimulation to the spinal cord without the need for insertion or implantation of stimulating electrodes. Previously, multifrequency transcutaneous stimulation has been demonstrated to penetrate to the spinal cord and lead to motor activation of detrusor and external urethral sphincter muscles. Here, we report on eight patients with idiopathic overactive bladder, who underwent 12 weeks of SCONE™ therapy. RESULTS: All patients reported statistically significant clinical improvement in multiple symptoms of overactive bladder, such as urinary urgency, frequency and urge incontinence. In addition, patients reported significant symptomatic improvements as captured by validated clinical surveys. CONCLUSION: SCONE™ therapy represents the first of its kind therapy to treat symptoms of urgency, frequency and urge urinary incontinence in patients with OAB. TRIAL REGISTRATION: The study was listed on clinicaltrials.gov ( NCT03753750 ).

Graphical models for mean and covariance of multivariate longitudinal data.

Joint mean-covariance modeling of multivariate longitudinal data helps to understand the relative changes among multiple longitudinally measured and correlated outcomes. A key challenge in the analysis of multivariate longitudinal data is the complex covariance structure. This is due to the contemporaneous and cross-temporal associations between multiple longitudinal outcomes. Graphical and data-driven tools that can aid in visualizing the dependence patterns among multiple longitudinal outcomes are not readily available. In this work, we show the role of graphical techniques: profile plots, and multivariate regressograms, in developing mean and covariance models for multivariate longitudinal data. We introduce an R package MLGM (Multivariate Longitudinal Graphical Models) to facilitate visualization and modeling mean and covariance patterns. Through two real studies, microarray data from the T-cell activation study and Mayo Clinic's primary biliary cirrhosis of the liver study, we show the key features of MLGM. We evaluate the finite sample performance of the proposed mean-covariance estimation approach through simulations.

Transcriptome dataset for RNA-seq analysis of axolotl embryonic oropharyngeal endoderm explants.

Animal nutrition and toxin deterrence rely on the ability to taste, which occurs through columnar taste cells clustered within taste buds. Taste buds in mammals are located within specialized tissues, called papillae. However, taste buds in fish and amphibians, such as axolotls (Ambystoma mexicanum), are not housed in papillae, rather they are embedded within the pharyngeal epithelium. This simplified tissue level organization, along with the ability of cultured oropharyngeal explants from early embryos to produce taste buds on the same time-line as embryos, make the axolotl an excellent model to identify molecules specifically involved in taste bud cell differentiation. We performed de novo transcriptomic analysis on RNA sequences from three different stages of oropharyngeal explants: stages 37/38, 39, and 41. RNA-seq data from 17 total samples representing these stages were pooled to generate a de novo assembly of the transcriptome using a Trinity pipeline. From 27.9Gb of raw sequences, we identified 21,244 transcripts. To our knowledge, this is the first published assembly of axolotl oropharyngeal endoderm explants. This data and transcriptome assembly relate to the research article "Transcriptome Analysis of Axolotl Oropharyngeal Explants During Taste Bud Differentiation Stages" (Kohli et al. 2020). This RNA-seq data and transcriptome assembly provide information on genes expressed in the oropharyngeal endoderm and will be valuable in the identification of taste bud development genes.

Transcriptome analysis of axolotl oropharyngeal explants during taste bud differentiation stages.

The Mexican salamander, Ambystoma mexicanum (Axolotl), is an excellent vertebrate model system to understand development and regeneration. Studies in axolotl embryos have provided important insights into taste bud development. Taste bud specification and determination occur in the oropharyngeal endoderm of axolotl embryos during gastrulation and neurulation, respectively, whereas taste bud innervation and taste cell differentiation occur later in development. Axolotl embryos are amenable to microsurgery, and tissue explants develop readily in vitro. We performed RNA-seq analysis to investigate the differential expression of genes in oropharyngeal explants at several stages of taste cell differentiation. Since the axolotl genome has only recently been sequenced, we used a Trinity pipeline to perform de novo assembly of sequencing reads. Linear models for RNA-seq data were used to identify differentially expressed genes. We found 1234 unique genes differentially expressed during taste cell differentiation stages. We validated four of these genes using RTqPCR and performed GO functional analysis. The differential expression of these genes suggests that they may play a role in taste cell differentiation in axolotls.

Understanding Male Caregivers' Emotional, Financial, and Physical Burden in the United States.

Men caregivers face caregiving burden, have weak support networks and are less likely to seek out programs which increase their caregiving capabilities and help them cope with this burden. Using the 2011 and 2015 National Study of Caregiving (NSOC) database and hierarchical regressions, we studied the emotional, financial, and physical burden of male caregivers as spouses, sons, and other caregivers by assessing the impact of caregiver characteristics, tasks and resources for each subgroup. We highlighted the importance of using a nationally representative database for men caregivers only and emphasized that these caregivers are not a monolithic group. We found that all caregivers experienced these three burden types, particularly elevated emotional stress, with sons reporting the highest emotional and financial strain levels. Assisting with personal care was the most stressful task and caregivers vastly under-utilized support and training. Our results suggest that burden suppressants included having family and friends help with caregiving, having time to decompress, and feeling appreciated by the care recipient. These findings offer insight for devising future policies that intentionally include relationship and burden type to encourage improved and more caregiving from men while supporting their well-being.

Primary and secondary prevention of ischemic heart disease in women.

Cardiovascular disease remains the number one cause of mortality among women. With increasing awareness of heart disease in women and increasing focus on including more women in trials, mortality from cardiovascular disease has fallen. Despite this, more women than men die from cardiovascular disease, and increasing cardiovascular disease is seen in young women. Preventive therapies have been the focus of recent guidelines to close this gap. In this review, data for primary and secondary prevention therapies for ischemic heart disease in women will be reviewed.

An update on exercise stress testing.

Exercise stress testing is the most commonly used noninvasive method to evaluate for coronary artery disease in men and women. Although emphasis has been placed on the diagnostic value of ST-segment depression, the exercise stress test provides other valuable diagnostic and prognostic data, beyond ST-segment depression. The value of these variables, which include exercise capacity, chronotropic response, heart rate recovery, blood pressure response, and the Duke Treadmill Score, are reviewed in this article. In addition, the gender differences seen with these exercise testing variables are reviewed. In this modern era of exercise stress testing, making use of all the information from a stress test and creating a comprehensive stress testing report are recommended in the evaluation of patients with suspected coronary artery disease who undergo exercise stress testing.
