The effect of 12 weeks of estriol cream on stress urinary incontinence post-menopause: A prospective multinational observational study.

OBJECTIVE: To quantitate the changes in stress urinary incontinence (SUI) outcome measures after 12 weeks of vaginal estriol cream in women with stress incontinence. METHODS: A prospective multicentre observational study conducted in tertiary urogynaecology centers. Postmenopausal women with pure SUI or stress predominant mixed urinary incontinence (MUI), not receiving any other treatment for their incontinence were given written instructions regarding digital application of a standard dose of vaginal estriol cream. Outcomes were measured at baseline and 12 weeks. The primary objective outcome was vaginal pH. The primary subjective outcome was the stress domain of the Urogenital Distress Inventory-6 (UDI-6). The secondary objective outcome used was the erect cough stress test. Two quality of life questionnaires and two patient reported outcomes were also included. RESULTS: The 46 postmenopausal recruits had a median age of 62.1 interquartile range (IQR 56.2-65.4). At follow up, the primary subjective outcome SUI domain [UDI-6] significantly improved from 83.3 (IQR 50-100) to 33.3 (33.3-66.7, p ≤ 0.001) as did vaginal pH [from 5.1 (4.9-5.9) to 4.9 (4.6-5.0] p ≤ 0.001; 18/43 patients (42%) were dry on cough stress test. CONCLUSIONS: Twelve weeks of vaginal estriol cream significantly reduced symptoms of stress urinary incontinence in this sample of postmenopausal women.

Efficacy and patient acceptability of the continence dish.

INTRODUCTION AND HYPOTHESIS: The continence dish has been a treatment option since 2002 for women with stress urinary incontinence (SUI) who decline surgery, but few quantitative objective efficacy data are published. We aimed to determine the efficacy and acceptability of this device for pure SUI or mixed incontinence (MUI). METHODS: Prospective interventional cohort study of 100 women with SUI or stress-predominant MUI who were interested to use the device; International Consultation on Incontinence Questionnaire (ICIQ) was primary outcome measure; 24-h pad test and Incontinence Impact Questionnaire (IIQ) were secondary outcomes. Acceptability was determined by device retention for 4 weeks, adverse events and ability to self-insert the device. RESULTS: Of 100 suitable women, 9 were not actually fitted, and 27 did not complete (acceptability: 64/100). The rate of adverse events was 7.7%, with 62.5% of users able to self-insert the device: 22 (34%) had pure SUI; 66% had MUI. In SUI, 68% were 'dry' on ICIQ median value 4.0 (IQR 2.5-8.5); 88% were dry on 24-h pad test (median 0.0, IQR 0.0-8.5). The "dry rate" was lower in MUI: 36% for ICIQ (median 9.0, IQR 5.0-15.0) and 62% for 24-h pad test (median 6.2, IQR 0.95-19.7). A "good" response on IIQ occurred in 88% of SUI and 69% of MUI. CONCLUSION: These new data showing strong objective benefits of the continence dish should be further validated by randomized trials, but this information should be made available to women seeking treatment options for SUI/MUI (particularly in view of concerns regarding mesh mid-urethral slings).

Serum concentrations of estriol vary widely after application of vaginal oestriol cream.

AIMS: The aim of this study was to establish the pharmacokinetic profile of serum oestriol (E3 ) concentrations over 24 h following application of vaginal E3 in chronic users (>12 weeks of E3 use). The interindividual and intraindividual differences before and after E3 were examined. METHODS: Ten women participated. Vaginal cream was omitted for ≥36 h prior to the study days. Blood sampling was performed for E3 , oestradiol and oestrone concentrations prior to cream application and at 1, 2, 3, 5, 8, 10, 12 and 24 h afterwards. In five women, all samples were repeated on a separate day. RESULTS: E3 was absorbed rapidly in most women. Peak serum E3 concentration occurred around 2 h (range 1-5 h). The decline in E3 concentrations was also rapid: falling <100 pmol L-1 in six out of ten women within 8 h and returning to ≤ 10 pmol L-1 at 24 h in nine out of the ten patients. Interindividual variability for peak concentrations was considerable (mean 546 pmol L-1 ; 95% CI 349-743). Area under the concentration-time curve (AUC) values over a dosage interval also varied widely: mean 2145 pmol.h L-1 ; 95% CI 1422-3233. However, repeated measurements in the same woman were highly (peaks: ρ = 0.94) or moderately (AUC: P = 0.74) correlated. CONCLUSIONS: Postmenopausal E3 concentrations are negligible. Serum E3 concentrations of chronic users of E3 cream varied greatly; however, concentrations declined rapidly within 8 h, generally reaching 'postmenopausal' levels by 24 h. The basis for the variation between subjects needs further elucidation. Additional research is required to establish the safety of topical E3 .

Effect of antibiotics on urine leakage in women with refractory detrusor overactivity: A phase IIb randomized trial.

AIM: Because bacterial cystitis is common in women with refractory detrusor overactivity, the aim was to compare the efficacy of 6 weeks of rotating antibiotics versus placebo, in conjunction with an anticholinergic, in controlling the symptoms of urge incontinence. METHODS: In a multicenter phase IIb double-blinded randomized placebo-controlled trial, women with urodynamically proven refractory detrusor overactivity were randomized in a 2:1 ratio of antibiotics versus placebo for 6 weeks, in addition to darifenacin for 6 months. Any woman with disabling cystitis symptoms was given appropriate antibiotics ("clinical override"). The primary outcome was the degree of urge incontinence change at 6 weeks and 6 months on 24-h pad test. Secondary outcomes were changes in leaks and voids per day measured on 3-day bladder diary and quality of life measures. Microbiological data were collected at all visits. RESULTS: Although 278 women were screened, only 36 were randomized and 33 (91.7%) completed the trial. Leakage on 24-h pad test decreased at 6 months by 75 g in patients receiving antibiotics versus 35 g in placebo. Cure of urge incontinence occurred at 6 months in 10/21 (48%) of antibiotics versus 2/12 (17%) of placebo. Clinical override, necessitating treatment of cystitis, occurred in 41.6% of placebo versus 16.7% of the antibiotic group by 6 months. CONCLUSION: Despite the small sample size, the study showed a significant reduction in pad leakage and leaks per day over 24 h in the active treatment group over a 6-month period. Nearly half of patients on placebo had disabling urinary tract infection symptoms that required clinical override treatment.

Inhibition of Bruton Tyrosine Kinase Reduces Neuroimmune Cascade and Promotes Recovery after Spinal Cord Injury.

Microglia/astrocyte and B cell neuroimmune responses are major contributors to the neurological deficits after traumatic spinal cord injury (SCI). Bruton tyrosine kinase (BTK) activation mechanistically links these neuroimmune mechanisms. Our objective is to use Ibrutinib, an FDA-approved BTK inhibitor, to inhibit the neuroimmune cascade thereby improving locomotor recovery after SCI. Rat models of contusive SCI, Western blot, immunofluorescence staining imaging, flow cytometry analysis, histological staining, and behavioral assessment were used to evaluate BTK activity, neuroimmune cascades, and functional outcomes. Both BTK expression and phosphorylation were increased at the lesion site at 2, 7, 14, and 28 days after SCI. Ibrutinib treatment (6 mg/kg/day, IP, starting 3 h post-injury for 7 or 14 days) reduced BTK activation and total BTK levels, attenuated the injury-induced elevations in Iba1, GFAP, CD138, and IgG at 7 or 14 days post-injury without reduction in CD45RA B cells, improved locomotor function (BBB scores), and resulted in a significant reduction in lesion volume and significant improvement in tissue-sparing 11 weeks post-injury. These results indicate that Ibrutinib exhibits neuroprotective effects by blocking excessive neuroimmune responses through BTK-mediated microglia/astroglial activation and B cell/antibody response in rat models of SCI. These data identify BTK as a potential therapeutic target for SCI.

The integrin αvß6 drives pancreatic cancer through diverse mechanisms and represents an effective target for therapy.

Pancreatic ductal adenocarcinoma (PDAC) has a 5-year survival rate of less than 4% and desperately needs novel effective therapeutics. Integrin αvß6 has been linked with poor prognosis in cancer but its potential as a target in PDAC remains unclear. We report that transcriptional expression analysis revealed that high levels of ß6 mRNA correlated strongly with significantly poorer survival (n = 491 cases, p = 3.17 × 10-8 ). In two separate cohorts, we showed that over 80% of PDACs expressed αvß6 protein and that paired metastases retained αvß6 expression. In vitro, integrin αvß6 promoted PDAC cell growth, survival, migration, and invasion. Treatment of both αvß6-positive human PDAC xenografts and transgenic mice bearing αvß6-positive PDAC with the αvß6 blocking antibody 264RAD, combined with gemcitabine, significantly reduced tumour growth (p < 0.0001) and increased survival (log-rank test, p < 0.05). Antibody therapy was associated with suppression of tumour cell activity (suppression of pErk growth signals, increased apoptosis seen as activated caspase-3) and suppression of the pro-tumourigenic microenvironment (suppression of TGFß signalling, fewer αSMA-positive myofibroblasts, decreased blood vessel density). These data show that αvß6 promotes PDAC growth through both tumour cell and tumour microenvironment mechanisms and represents a valuable target for PDAC therapy. © 2019 The Authors.

Estriol serum levels in new and chronic users of vaginal estriol cream: A prospective observational study.

AIMS: To quantify estriol serum concentrations in "new" and "chronic users" of topical estriol cream using quantitative liquid chromatography tandem mass spectrometry. METHODS: In this singlecentre prospective observational study, postmenopausal women with urogynaecological complaints were enrolled: 40 had not used topical estriol previously ("new users") and 50 had been applying estriol cream for more than 12 weeks ("chronic users"). In "new users," serum estriol levels were measured at baseline and after 12 weeks use. Estriol cream 1 mg/g was used daily for 3 weeks, then twice weekly with applicator (group 1A) or digitally (group 1B) or three times per week digitally (group 1C). "Chronic users" applied the cream twice (n = 7) or three (n = 43) times per week. Serum samples were taken in the morning after using cream the previous night. The main outcome measures were estriol serum concentrations in "new" and "chronic users" of estriol cream. RESULTS: Baseline serum estriol concentrations were less than 5 pmol/L in all 40 "new users." At 12 weeks, the 12-hour serum estriol levels ranged from less than 5 to 494 pmol/L (median 22.8; Interquartile range [IQR] 9.2-108.5). Seven "new users" had levels more than 100 pmol/L. Most of the 50 "chronic users" also had 12-hour levels less than 100 pmol/L (median 15.1 pmol/L [IQR 2.7-33.9]: three had levels more than 100 pmol/L. CONCLUSIONS: This study reports serum estriol concentrations in a large number of "new" and "chronic users" of vaginal estriol cream, employing a novel highly sensitive and specific technique. Overall, the results are reassuring: 87% had 12-hour estriol levels less than 100 pmol/L.

Consensus-based good practice guidelines for clinical psychologists to support care staff in enabling sexual expression in people with intellectual disabilities-A Delphi study.

BACKGROUND: Care staff supporting people with intellectual disabilities (PWID) report accepting views on PWID's sexual expression, but people with intellectual disabilities report their sexual expression is restricted by care staff. METHODS: We recruited a panel of 17 UK clinical psychologists experienced in helping care staff support PWID's sexual expression. We used the Delphi Method to develop consensus-based practice guidelines for UK clinical psychologists supporting care staff in this way. RESULTS: Having proposed three guidelines each in Round One, panel members reached consensus (≥90% agreement) that 12 were important, falling under four themes: "Addressing staff attitudes," "Addressing uncertainty about rights and responsibilities of people with intellectual disabilities," "Locating the problem, being part of the solution," and "Supporting care staff to understand and reflect upon their role." CONCLUSIONS: Clinical psychologists help care staff support PWID's sexual expression by normalizing care staff concerns, encouraging reflection, clarifying PWID's rights, and prompting those at managerial and service level to support care staff.

Distinct mechanisms of regulation of the ITGA6 and ITGB4 genes by RUNX1 in myeloid cells.

Integrins are transmembrane adhesion receptors that play an important role in hematopoiesis by facilitating interactions between hematopoietic cells and extracellular matrix components of the bone marrow and hematopoietic tissues. These interactions are important in regulating the function, proliferation, and differentiation of hematopoietic cells, as well as their homing and mobilization in the bone marrow. Not surprisingly altered expression and function of integrins plays a key role in the development and progression of cancer including leukemias. However, the regulation of integrin gene expression is not well characterized and the mechanisms by which integrin genes are disrupted in cancer remain unclear. Here we demonstrate for the first time that a key regulator of hematopoiesis, RUNX1, binds to and regulates the promoters of both the ITGA6 and ITGB4 genes in myeloid cells. The ITGA6 and ITGB4 integrin genes form the α6ß4 integrin receptor. However, our data indicate that RUNX1 functions differently at these two promoters. RUNX1 regulates ITGA6 through a consensus RUNX1 binding motif in its promoter. In contrast, although the ITGB4 promoter is also activated by RUNX1, it does so in the absence of a recognized consensus RUNX1 binding motif. Furthermore, our data suggest that regulation of ITGB4 may involve interactions between the promoter and upstream regulatory elements.

NKA enhances bladder-afferent mechanosensitivity via urothelial and detrusor activation.

Tachykinins are expressed within bladder-innervating sensory afferents and have been shown to generate detrusor contraction and trigger micturition. The release of tachykinins from these sensory afferents may also activate tachykinin receptors on the urothelium or sensory afferents directly. Here, we investigated the direct and indirect influence of tachykinins on mechanosensation by recording sensory signaling from the bladder during distension, urothelial transmitter release ex vivo, and direct responses to neurokinin A (NKA) on isolated mouse urothelial cells and bladder-innervating DRG neurons. Bath application of NKA induced concentration-dependent increases in bladder-afferent firing and intravesical pressure that were attenuated by nifedipine and by the NK2 receptor antagonist GR159897 (100 nM). Intravesical NKA significantly decreased bladder compliance but had no direct effect on mechanosensitivity to bladder distension (30 µl/min). GR159897 alone enhanced bladder compliance but had no effect on mechanosensation. Intravesical NKA enhanced both the amplitude and frequency of bladder micromotions during distension, which induced significant transient increases in afferent firing, and were abolished by GR159897. NKA increased intracellular calcium levels in primary urothelial cells but not bladder-innervating DRG neurons. Urothelial ATP release during bladder distention was unchanged in the presence of NKA, whereas acetylcholine levels were reduced. NKA-mediated activation of urothelial cells and enhancement of bladder micromotions are novel mechanisms for NK2 receptor-mediated modulation of bladder mechanosensation. These results suggest that NKA influences bladder afferent activity indirectly via changes in detrusor contraction and urothelial mediator release. Direct actions on sensory nerves are unlikely to contribute to the effects of NKA.

A prospective "bottom up" study of the costs of faecal incontinence in ambulatory patients.

BACKGROUND AND AIM: The few studies that have examined direct costs of faecal incontinence are limited in that they employed retrospective databases, postal surveys, and focused upon institutionalised patients or post partum women. The aim of the current study was to identify the direct pre-treatment costs of faecal incontinence expended by a range of home dwelling patients and identify relationships between costs and severity of incontinence. METHODS: Consecutive patients attending an outpatient clinic for treatment of faecal incontinence were interviewed using a questionnaire, modeled on the Dowel Bryant Incontinence Cost Index. The information collected included costs of: (i) basic personal hygiene: pads, laundry, wipes, cleansers; (ii) medication: loperamide, creams and stool bulking agents; and (iii) diagnostic: medical attendance, anorectal physiology, colonoscopy. Costs were broken down into personal expenses, government costs, and costs to health funds. A St Mark's Faecal Incontinence Severity Score was recorded. RESULTS: A total of 100 consecutive patients consented (15 males, 85 females) mean age 70.8 (SD12) years. Mean St Mark's score was 12 (SD4.5). The median total patient cost was $437.72 AUD (range 0-2807) per annum. Government costs were $537AUD (range 135-1657), and health fund median $0 AUD (0-1628). Incontinence severity correlated with personal expense only median $283.75AUD (range 0-2350). The aged were more incontinent but costs did not increase in relation to age. CONCLUSION: Faecal incontinence results in a substantial financial burden for both patients and Government. Effective treatments which relieve the financial burden of faecal incontinence, are likely to be economically advantageous into the future for both patients and Government.

Vascular measures of atherosclerosis in detrusor overactivity and controls.

AIM: The mechanisms leading to the development of detrusor overactivity (DO) are still relatively poorly understood, however, animal studies suggest that atherosclerosis and reduced blood flow to the bladder may be one etiological pathway. Thus, the aim of this study was to evaluate signs of atherosclerosis in a large cohort of women with detrusor overactivity, using two precise measures of atherosclerotic vascular impairment, Ankle Brachial Index (ABI), and Brachial-ankle Pulse Wave Velocity (baPWV). METHODS: A prospective cohort study measuring ABI and baPWV of women with DO and controls was conducted. The ABI and baPWV were measured using an automated oscillometric blood pressure machine, to evaluate the degree of atherosclerosis in patients with DO and controls. Associations between ABI and baPWV and important confounding variables were assessed by a linear regression model. RESULTS: Ninety-eight women with DO, and 98 controls without any symptoms of DO were studied. Multivariate analysis showed an increase in left baPWV of approximately 96 cm/s units of velocity (95%CI 20.65-172.05, P = 0.01) is predicted significantly by the presence or absence of detrusor overactivity (as well by independent factors of age, diastolic blood pressure and body mass index). A similar effect was seen for right baPWV. CONCLUSIONS: On linear regression modeling, the presence of DO was a strong predictor for an increased PWV when controlling for age, BMI and diastolic blood pressure (DBP), thus supporting the hypothesis that atherosclerosis may contribute to the etiology of DO.

The urinary microbiome in patients with refractory urge incontinence and recurrent urinary tract infection.

INTRODUCTION AND HYPOTHESIS: Urinary urge incontinence is a chronic, debilitating condition that is difficult to treat. Patients refractory to standard antimuscarinic therapy often experience recurrent urinary tract infections (rUTIs). The microbiota of these refractory patients with rUTI remains unexplored. METHODS: A midstream urine (MSU) sample was collected from patients with refractory urge incontinence and coexistent rUTI during acute symptomatic episodes. Culture-based diagnosis was performed using routine microbiological methods. Culture-independent profiling was performed using bacterial 16S RNA profiling. E. coli strain typing was performed by amplicon pyrosequencing of the fimH gene. RESULTS: Over 2 years, 39 patients with refractory urge incontinence and coexistent rUTI were studied, yielding 9 severely affected cases. These 9 patients were carefully monitored for a further 2 years, resulting in the collection of 102 MSU samples, 70 of which were diagnosed as UTI (median of 8 UTIs/woman). Culture-independent analysis of 38 of these samples revealed the existence of a diverse urinary microbiota. Strain typing of E. coli identified instances of rUTI caused by the same persisting strain and by new infecting strains. CONCLUSIONS: Patients with refractory urge incontinence and coexistent rUTI possess a diverse urinary microbiota, suggesting that persistent bladder colonisation might augment the pathology of their chronic condition.

Expression and localization of pannexin-1 and CALHM1 in porcine bladder and their involvement in modulating ATP release.

ATP release from urinary bladder is vital for afferent signaling. The aims of this study were to localize calcium homeostasis modulator 1 (CALHM1) and pannexin-1 expression and to determine their involvement in mediating ATP release in the bladder. To determine gene expression and cellular distribution, PCR and immunohistochemistry were performed, respectively, in the porcine bladder. CALHM1 and pannexin-1-mediated ATP release in response to hypotonic solution (0.45% NaCl)-induced stretch, and extracellular Ca2+ depletion ([Ca2+]0) was measured in isolated urothelial, suburothelial, and detrusor muscle cells. CALHM1 and pannexin-1 mRNA and immunoreactivity were detected in urothelial, suburothelial, and detrusor muscle layers, with the highest expression on urothelium. Hypotonic stretch caused a 2.7-fold rise in ATP release from all three cell populations (P < 0.01), which was significantly attenuated by the pannexin-1 inhibitor, 10Panx1, and by the CALHM1 antibody. Brefeldin A, a vesicular transport inhibitor, and ruthenium red, a nonselective CALHM1 channel blocker, also significantly inhibited stretch-mediated ATP release from urothelial cells. [Ca2+]0 caused a marked, but transient, elevation of extracellular ATP level in all three cell populations. CALHM1 antibody and ruthenium red inhibited [Ca2+]0-induced ATP release from urothelial cells, but their effects on suburothelial and detrusor cells were insignificant. 10Panx1 showed no significant inhibition of [Ca2+]0-induced ATP release in any types of cells. The results presented here provide compelling evidence that pannexin-1 and CALHM1, which are densely expressed in the porcine bladder, function as ATP release channels in response to bladder distension. Modulation of extracellular Ca2+ may also regulate ATP release in the porcine bladder through voltage-gated CALHM1 ion channels.

Does motivation predict outcome of pelvic floor muscle retraining?

AIMS: Although pelvic floor muscle training (PFMT) is effective for stress urinary incontinence (SUI), patients need to be motivated to obtain cure. An instrument to assess motivation in such patients was published in 2009: the Incontinence Treatment Motivation Questionnaire (ITMQ). The ITMQ consists of five domains: (i) positive attitudes toward PFMT; (ii) reasons for not doing PFMT; (iii) difficulties living with incontinence; (iv) desire for treatment; and (v) incontinence severity influencing motivation. The aim of the present study was to examine the relationship between ITMQ scores and treatment success. METHODS: After referral for PFMT, women with SUI completed the ITMQ. Pre- and post-treatment outcomes were the International Consultation on Incontinence Questionnaire (ICIQ) score and a 24-hr pad test. Correlations between ITMQ scores and baseline, as well as post-treatment change in ICIQ scores and pad test results were examined. Additionally, the demographics of non-participants, participants, and patients lost to follow-up were compared. RESULTS: Of 85 recruits, 18 did not complete the ITMQ, 14 were lost to follow-up, thus 53 completed the PFMT programme and undertook either one or both outcomes. Pre-treatment, severity on ICIQ correlated with total ITMQ (ρ = 0.33, P = 0.01). Post-treatment change in pad test was inversely correlated with Domain 2 (ρ = -0.33, P = 0.03). CONCLUSIONS: The pre-treatment severity of incontinence was significantly associated with motivation for treatment. Unfortunately, post-treatment change correlated with only one domain of the questionnaire. Further modification of the ITMQ is envisaged. Neurourol.

Development of a core set of outcome measures for OAB treatment.

INTRODUCTION AND HYPOTHESIS: Standardized measures enable the comparison of outcomes across providers and treatments giving valuable information for improving care quality and efficacy. The aim of this project was to define a minimum standard set of outcome measures and case-mix factors for evaluating the care of patients with overactive bladder (OAB). METHODS: The International Consortium for Health Outcomes Measurement (ICHOM) convened an international working group (WG) of leading clinicians and patients to engage in a structured method for developing a core outcome set. Consensus was determined by a modified Delphi process, and discussions were supported by both literature review and patient input. RESULTS: The standard set measures outcomes of care for adults seeking treatment for OAB, excluding residents of long-term care facilities. The WG focused on treatment outcomes identified as most important key outcome domains to patients: symptom burden and bother, physical functioning, emotional health, impact of symptoms and treatment on quality of life, and success of treatment. Demographic information and case-mix factors that may affect these outcomes were also included. CONCLUSIONS: The standardized outcome set for evaluating clinical care is appropriate for use by all health providers caring for patients with OAB, regardless of specialty or geographic location, and provides key data for quality improvement activities and research.

The Effect of Vaginal Oestriol Cream on Subjective and Objective Symptoms of Stress Urinary Incontinence and Vaginal Atrophy: An International Multi-Centre Pilot Study.

AIM: Subjectively and objectively assess stress urinary incontinence (SUI) symptoms before and after topical oestrogen therapy. METHODS: A prospective study was performed in 3 centres in South-Africa, Australia and the Netherlands. Postmenopausal women with SUI were treated with topical oestriol cream for 6 weeks. The primary subjective outcome was the Patient's Global Impression of Improvement (PGI-I) scale. The primary objective outcome was vaginal pH. Secondary subjective outcomes were: the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form, the Incontinence Impact Questionnaire, the Urogenital Distress Inventory (UDI-6) and the most bothersome symptom approach. Secondary objective outcome was the erect cough pad test. Compliance was scored. RESULTS: A total of 68 women were enrolled. Half of the participants reported improvement on the PGI-I scale after treatment. Vaginal pH was significantly lower after treatment (median 5.3 (interquartile range (IQR) 4.5-6.0) vs. 5.0 (4.4-5.4), p = 0.002). Improvement on the UDI stress domain was observed (p = 0.01). No statistically significant differences were found in the other subjective outcomes. Baseline and repeat cough pad tests demonstrated a wide variation with no significant difference. Compliance was high (median 100 (IQR 83-100%)). CONCLUSION: Topical oestriol cream during 6 weeks improved quality of life and vaginal pH but no other objective measures of incontinence.

The Leukemia Inhibitory Factor Receptor Gene Is a Direct Target of RUNX1.

Activation of cytokine signaling via the leukemia inhibitory factor receptor (LIFR) plays an integral role in hematopoiesis, osteogenesis, and placental development, along with mediating neurotrophic mechanisms. However, the regulatory control of the LIFR gene has remained largely unexplored. Here, we characterize the LIFR gene as a novel target of the RUNX1 transcription factor. The RUNX1 transcription factor is an essential regulator of hematopoiesis and is a frequent target of point mutations and chromosomal alterations in leukemia. RUNX1 regulates hematopoiesis through its control of genes important for hematopoietic cell growth, proliferation, and differentiation, including a number of cytokines and cytokine receptors. LIFR is regulated by two alternate promoters: a placental-specific and a ubiquitously active general promoter. We show that both of these promoters are regulated by RUNX1. However, in myeloid cells LIFR expression is driven solely by the general LIFR promoter with our data indicating that the placental promoter is epigenetically silenced in these cells. While RUNX1 activates the LIFR general promoter, the oncogenic RUNX1-ETO fusion protein generated by the t(8;21) translocation commonly associated with acute myeloid leukemia represses promoter activity. The data presented here establish LIFR as a transcriptional target of RUNX1 and suggest that disruption of RUNX1 activity in myeloid cells may result in altered LIFR signaling in these cells.

Pelvic floor dysfunction in female Sjögren's syndrome: an 8-year audit.

INTRODUCTION AND HYPOTHESIS: The classic triad of dry eyes, mouth and vagina is known to most gynaecologists as pathognomonic of Sjögren's syndrome, but rheumatologists seldom consider vaginal symptoms. Our hypothesis was that women with Sjögren's syndrome would have an increased likelihood of postoperative voiding dysfunction, severe vaginal stenosis or poor response to anticholinergics compared with the general urogynaecology patient. METHODS: All patients with Sjögren's syndrome were prospectively recorded from July 2007 to June 2015. Presenting complaint, pelvic examination findings, previous/subsequent pelvic surgery, voiding dysfunction and response to anticholinergics were noted. The denominator, all new urogynaecology patients, was prospectively recorded. RESULTS: Fifteen patients were identified over 8 years (0.5 % of 2794 new presentations). Of the seven patients who had previously undergone surgery elsewhere, all had demonstrable pelvic tissue fibrosis; five had such severe fibrosis that no speculum could be passed. Anticholinergic medications were completely intolerable in 10/11 (91 %) women, and severe postoperative voiding dysfunction occurred in 6/9 (67 %) women. Only 2/15 (13 %) women were unaffected by fibrosis, postoperative voiding dysfunction or intolerance to anticholinergics. CONCLUSIONS: This audit demonstrates a substantial risk of vaginal stenosis, postoperative voiding dysfunction or severe intolerance to anticholinergics in women with Sjögren's syndrome.

Objective efficacy of the tension-free vaginal tape in obese/morbidly obese women versus non-obese women, at median five year follow up.

BACKGROUND: One subjective long-term evaluation of the tension-free vaginal tape (TVT) success rate in obese women showed a worse prognosis in the obese, but objective studies have been limited to short-term follow-up (less than two years). AIM: To determine whether the long-term objective cure rate in obese/morbidly obese women who underwent TVT was reduced, compared to non-obese women (at five or more years). MATERIALS AND METHODS: Body mass index (BMI) was collected on patients undergoing TVT procedure. Recruited patients were asked to perform a 24 h pad test and complete an International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) at five years postoperatively. Data was analyzed according to pre-operative urodynamic diagnoses and BMI, using 'routine' and 'strict' objective definitions of objective cure. RESULTS: At median follow-up of 64 months (interquartile range 58-80 months), 136 patients returned a pad test and ICIQ-SF. Using a routine definition of cure (pad test of ≤10 g in a 24 h period), 96% of patients were cured overall. The BMI results (n = 119 patients) were stratified into ≤25, 25.1-35 and ≥35.1 kg/m2 , which represented 41, 53 and 6% of patients, respectively. The routine cure rates for these three groups were 98, 97 and 71%, respectively (P = 0.004). CONCLUSION: Long-term objective outcomes of the TVT in morbidly obese women are significantly poorer than in women with a normal BMI.
