BACKGROUND: Although specialists are skilled in the management of urinary incontinence, primary care clinicians are integral in early diagnosis and initiation of management in order to decrease overuse of specialty care and improve the quality of specialist visits. We measured the quality of incontinence care provided by primary care clinicians prior to referral to a specialist and evaluated the impact of provider variables on quality of care. METHODS: We performed a retrospective review of 200 women referred for urinary incontinence to a Female Pelvic Medicine and Reconstructive Surgery specialist between March 2017 and July 2018. We measured primary care adherence to 12 quality indicators in the 12 months prior to specialist consultation. We stratified adherence to quality indicators by clinician sex and years of experience. RESULTS: Half of women with incontinence underwent a pelvic examination or had a urinalysis ordered. Few patients with urge urinary incontinence were recommended behavioral therapy (14%) or prescribed medication (8%). When total aggregate scores were compared, female clinicians performed the recommended care 47% ± 25% of the time, compared with 35% ± 23% for male clinicians (P = .003). Increasing years of experience was associated with worse overall urinary incontinence care (r -0.157, P = .02). CONCLUSIONS: We found low rates of adherence to a set of quality indicators for women with urinary incontinence, with male clinicians performing significantly worse than female clinicians. Improvement of incontinence care in primary care could significantly reduce costs of care and preserve outcomes.

Objective

To address a deficiency in clinical trial and research enrollment in gynecologic cancer studies, we launched a paper based patient research registry. To improve registry enrollment, we transitioned to an online registry and trial matching mechanism to aid women in accessing open studies.

Methods

Utilizing a validated verification platform, we designed a web-based registry and trial matching mechanism for women over age 18. Participants completed a questionnaire to provide information for trial matching. A focus group of registry participants was held 9 months after the start of the study to evaluate barriers to participation.

Results

A total of 322 women were enrolled in the online registry over a 14 month period which was a 4.3 fold increase over the paper-based registry (p<0.0001). Two hundred and sixty three (82%) women were matched to at least one study. Fifteen percent (39/263) of those eligible for studies went on to enroll. The online enrollment rate to studies was not different from that observed in the paper-based registry (26/172, p=0.934), however, the web-based registry linked participants to subsequent studies 27% more rapidly (68 (+/-98) days vs. 93 (+/-81) days for the paper-based registry, p=0.017). Focus group participants identified areas for improvement.

Conclusion

Web-based patient driven registry provides dramatic improvement in the number of participants enrolled and the time to trial linkage compared to a paper based registry at a single institution. Further studies of barriers to research participation are necessary to improve on this model.

Abstract Background Classically protein kinase A (PKA) and transcription factor activator protein 1 (AP-1) mediate the cyclic AMP (cAMP) induced-corticotrophin releasing hormone (CRH) expression in the placenta. However enteric Gram (-) bacterial cell wall component lipopolysaccharide (LPS) may also induce-CRH expression via Toll like receptor (TLR)4 and its adaptor molecule Myd88. Here we investigated the role of MyD88, TRIF and IRAK2 on cAMP-induced CRH promoter activation in JEG3 cells in the absence of LPS/TLR4 stimulation. Methods JEG3 cells were transfected with CRH-luciferase and Beta-galactosidase expression vectors and either empty or dominant-negative (DN)-MyD88, DN-TRIF or DN-IRAK2 vectors using Fugene6 (Roche). cAMP-induced CRH promoter activation was examined by using a luminometer and luciferase assay. Calorimetric Beta-galactosidase assays were performed to correct for transfection efficiency. Luciferase expression vectors of cAMP-downstream molecules, CRE and AP-1, were used to further examine the signaling cascades. Results cAMP stimulation induced AP-1 and CRE promoter expression and led to dose-dependent CRH promoter activation in JEG3 cells. Inhibition of MyD88 signaling blocked cAMP-induced CRE and CRH promoter activation. Inhibition of TRIF signaling blocked cAMP-induced CRH but not CRE expression, while inhibition of IRAK2 did not have an effect on cAMP-induced CRH expression. Conclusion MyD88 and TRIF exert direct regulatory effect on cAMP-induced CRH promoter activation in JEG3 cells in the absence of infection. MyD88 most likely interacts with molecules upstream of IRAK2 to regulate cAMP-induced CRH expression.

Objective

Health care providers are increasingly being evaluated by the quality of care they provide. Our aim was to assess the feasibility of recently developed quality indicators (QIs) for pelvic organ prolapse (POP) and identify possible deficits in care.

Study design

A panel ranked 14 QIs based on the RAND appropriateness method assessing screening and diagnosis, pessary management, and surgery for POP. Retrospective chart abstraction was performed after identifying patients with a diagnosis of POP evaluated within a hospital-based multispecialty group using International Classification of Diseases, ninth edition, diagnosis codes.

Results

Of 283 patients identified, 98% of those with a new complaint of vaginal bulge had a pelvic examination. The POP was described but not staged in 6% and not documented at all in 25.1%. Among those managed with pessaries, 98% had vaginal examinations at least every 6 months. Forty-nine percent of the patients who had surgery had complete preoperative POP staging. Only 20% of women undergoing apical surgery had documentation of counseling regarding different surgical options, and of the women who underwent a hysterectomy for POP, only 48% had a concomitant vault suspension. Although 71% had documentation about the risk of postoperative stress incontinence, only 14.5% had documented counseling regarding risks of mesh. Only 37% of patients implanted with mesh for POP had documented follow-up at 1 year. An intraoperative cystoscopy was performed in 86% undergoing cystocele repair or apical surgery.

Conclusion

The quality of care for women with POP can be feasibly measured with QIs. Processes of care were deficient in many areas, and our findings can serve as a basis for quality improvement interventions.

Objective

To determine whether BRCA carriers have a decreased ovarian reserve compared with women without BRCA mutations, because BRCA mutations may lead to accelerated oocyte apoptosis due to accumulation of damaged DNA.

Design

Cross-sectional study.

Setting

Academic tertiary care center.

Patient(s)

A total of 143 women, aged 18-45 years, who underwent clinical genetic testing for BRCA deleterious mutations because of a family history of cancer, were included. The cohort was classified into three groups: BRCA1 carriers, BRCA2 carriers, and women without BRCA mutations (controls). None had a personal history of breast or ovarian cancer.

Intervention(s)

None.

Main outcome measure(s)

The main outcome was serum antimüllerian hormone (AMH) level. Linear and logistic regression models adjusting for age and body mass index (BMI) were performed to determine the association between BRCA mutations and AMH.

Result(s)

BRCA1 mutation carriers had a significant decrease in AMH levels compared with controls after adjusting for age and BMI (0.53 ng/mL [95% confidence interval (CI) 0.33-0.77 ng/mL] vs. 1.05 ng/mL [95% CI 0.76-1.40 ng/mL]). Logistic regression confirmed that BRCA1 carriers had a fourfold greater odds of having AMH <1 ng/mL compared with controls (odds ratio 4.22, 95% CI 1.48-12.0). There was no difference in AMH levels between BRCA2 carriers and controls.

Conclusion(s)

BRCA1 carriers have lower age- and BMI-adjusted serum AMH levels compared with women without BRCA mutations. Our results contribute to the current body of literature regarding BRCA carriers and their reproductive outcomes. Larger prospective studies with clinical outcomes such as infertility and age at menopause in this population are needed to further substantiate our findings.

Purpose

Our aim was to test the feasibility of a set of quality of care indicators for urinary incontinence and at the same time measure the care provided to women with urinary incontinence in 2 clinical settings.

Materials and methods

This was a pilot test of a set of quality of care indicators. A total of 20 quality of care indicators were previously developed using the RAND Appropriateness Method. These quality of care indicators were used to measure care received for 137 women with a urinary incontinence diagnosis in a 120-physician hospital based multispecialty medical group. We also performed an abstraction of 146 patient records from primary care offices in Southern California. These charts were previously used as part of ACOVE (Assessing Care of Vulnerable Elders Project). As a post-hoc secondary analysis, the 2 populations were compared with respect to quality, as measured by compliance with the quality of care indicators.

Results

In the ACOVE population, 37.7% of patients with urinary incontinence underwent a pelvic examination vs 97.8% in the multispecialty medical group. Only 15.6% of cases in the multispecialty medical group and 14.2% in ACOVE (p = 0.86) had documentation that pelvic floor exercises were offered. Relatively few women with a body mass index of greater than 25 kg/m(2) were counseled about weight loss in either population (20.9% multispecialty medical group vs 26.1% ACOVE, p = 0.76). For women undergoing sling surgery, documentation of counseling about risks was lacking and only 9.3% of eligible cases (multispecialty medical group only) had documentation of the risks of mesh.

Conclusions

Quality of care indicators are a feasible means to measure the care provided to women with urinary incontinence. Care varied by population studied and yet deficiencies in care were prevalent in both patient populations studied.

Background

Heart failure with preserved ejection fraction (HFpEF) represents approximately half of heart failure, and its incidence continues to increase. The leading cause of mortality in HFpEF is sudden death, but little is known about the underlying mechanisms.

Methods

Dahl salt-sensitive rats were fed a high-salt diet (8% NaCl) from 7 weeks of age to induce HFpEF (n=38). Rats fed a normal-salt diet (0.3% NaCl) served as controls (n=13). Echocardiograms were performed to assess systolic and diastolic function from 14 weeks of age. HFpEF-verified and control rats underwent programmed electrical stimulation. Corrected QT interval was measured by surface ECG. The mechanisms of ventricular arrhythmias (VA) were probed by optical mapping, whole-cell patch clamp to measure action potential duration and ionic currents, and quantitative polymerase chain reaction and Western blotting to investigate changes in ion channel expression.

Results

After 7 weeks of a high-salt diet, 31 of 38 rats showed diastolic dysfunction and preserved ejection fraction along with signs of heart failure and hence were diagnosed with HFpEF. Programmed electric stimulation demonstrated increased susceptibility to VA in HFpEF rats (P<0.001 versus controls). The arrhythmogenicity index was increased (P<0.001) and the corrected QT interval on ECG was prolonged (P<0.001) in HFpEF rats. Optical mapping of HFpEF hearts demonstrated prolonged action potentials (P<0.05) and multiple reentry circuits during induced VA. Single-cell recordings of cardiomyocytes isolated from HFpEF rats confirmed a delay of repolarization (P=0.001) and revealed downregulation of transient outward potassium current (I_to; P<0.05). The rapid components of the delayed rectifier potassium current (I_Kr) and the inward rectifier potassium current (I_K1) were also downregulated (P<0.05), but the current densities were much lower than for I_to. In accordance with the reduction of I_to, both Kcnd3 transcript and Kv4.3 protein levels were decreased in HFpEF rat hearts.

Conclusions

Susceptibility to VA was markedly increased in rats with HFpEF. Underlying abnormalities include QT prolongation, delayed repolarization from downregulation of potassium currents, and multiple reentry circuits during VA. Our findings are consistent with the hypothesis that potassium current downregulation leads to abnormal repolarization in HFpEF, which in turn predisposes to VA and sudden cardiac death.

Sudden death is the most common mode of exodus in patients with heart failure and preserved ejection fraction (HFpEF). Cardiosphere-derived cells (CDCs) reduce inflammation and fibrosis in a rat model of HFpEF, improving diastolic function and prolonging survival. We tested the hypothesis that CDCs decrease ventricular arrhythmias (VAs) and thereby possibly contribute to prolonged survival. Dahl salt-sensitive rats were fed a high-salt diet to induce HFpEF. Allogeneic rat CDCs (or phosphate-buffered saline as placebo) were injected in rats with echo-verified HFpEF. CDC-injected HFpEF rats were less prone to VA induction by programmed electrical stimulation. Action potential duration (APD) was shortened, and APD homogeneity was increased by CDC injection. Transient outward potassium current density was upregulated in cardiomyocytes from CDC rats relative to placebo, as were the underlying transcript (Kcnd3) and protein (Kv4.3) levels. Fibrosis was attenuated in CDC-treated hearts, and survival was increased. Sudden death risk also trended down, albeit nonsignificantly. CDC therapy decreased VA in HFpEF rats by shortening APD, improving APD homogeneity, and decreasing fibrosis. Unlike other stem/progenitor cells, which often exacerbate arrhythmias, CDCs reverse electrical remodeling and suppress arrhythmogenesis in HFpEF.

Sudden death is the most common mode of mortality in patients with heart failure and preserved ejection fraction (HFpEF). Ventricular arrhythmias (VA) have been suspected as the etiology but the supporting evidence in patients with HFpEF is scarce. We sought to investigate VA prevalence, and to determine if VA are associated with prolonged repolarization, in patients with HFpEF. In a retrospective case-control study design, Cedars-Sinai patients who underwent prolonged ambulatory electrocardiographic monitoring (Zio Patch) between 2016 and 2018 were screened for a clinical diagnosis of HFpEF. Patients with normal diastolic and systolic function who underwent Zio Patch monitoring were also reviewed as controls. Multivariable logistic regression was used to compare the prevalence of rhythm disturbances in patients with and without HFpEF. Ventricular tachycardia (VT) was more prevalent in patients with HFpEF (37% vs. 16% in controls, p = 0.001). Most episodes were non-sustained except for one case of sustained VT in a patient with HFpEF. Covariate-adjusted logistic regression including HFpEF diagnosis, age, sex, body mass index, and the presence of comorbidities revealed that only HFpEF was associated with increased risk of VT (relative risk 2.86, p = 0.023). Subgroup-analyses revealed an association between increased QTc interval and risk of VT (460 ± 38 ms in HFpEF patients with VT vs. 445 ± 28 ms in HFpEF patients without VT, p = 0.03). Non-sustained VT was more prevalent in patients with HFpEF compared to patients without HFpEF, and QTc interval prolongation was associated with VT in HFpEF.
