Percutaneous breast biopsy: effect on short-term quality of life.

PURPOSE: To examine the effects of percutaneous breast biopsy on short-term quality of life. MATERIALS AND METHODS: The institutional review board approved this HIPAA-compliant prospective study. From December 1, 2007, through February 28, 2010, women undergoing percutaneous breast biopsy in an academic medical center were recruited to participate in a mixed-mode survey 2-4 days after biopsy. Patients described their biopsy experience by using the Testing Morbidities Index (TMI), a validated instrument for assessing short-term quality of life related to diagnostic testing. The scale ranged from 0 (worst possible experience) to 100 (no adverse effects). Seven attributes were assessed: pain or discomfort before and during testing, fear or anxiety before and during testing, embarrassment during testing, and physical and mental function after testing. Demographic and clinical information were also collected. Univariate and multivariate linear regression analyses were performed to identify significant predictors of TMI score. RESULTS: In 188 women (mean age, 51.4 years; range, 22-80 years), the mean TMI score (±standard deviation) was 82 ± 12. Univariate analysis revealed age and race as significant predictors of the TMI score (P < .05). In the multivariate model, only patient age remained a significant independent predictor (P = .001). TMI scores decreased by approximately three points for every decade decrease in patient age, which suggests that younger women were more adversely affected by the biopsy experience. CONCLUSION: Younger patient age is a significant predictor of decreased short-term quality of life related to percutaneous breast biopsy procedures. Tailored prebiopsy counseling may better prepare women for percutaneous biopsy procedures and improve their experience.

Mechanisms and management of hypertension in autosomal dominant polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is the most commonly inherited kidney disease, characterized by progressive cyst growth and renal enlargement, resulting in renal failure. Hypertension is common and occurs early, prior to loss of kidney function. Whether hypertension in ADPKD is a primary vasculopathy secondary to mutations in the polycystin genes or secondary to activation of the renin-angiotensin-aldosterone system by cyst expansion and intrarenal ischemia is unclear. Dysregulation of the primary cilium causing endothelial and vascular smooth muscle cell dysfunction is a component of ADPKD. In this article, we review the epidemiology, pathophysiology and clinical characteristics of hypertension in ADPKD and give specific recommendations for its treatment.

SMARTWOMAN™: Feasibility assessment of a smartphone app to control cardiovascular risk factors in vulnerable diabetic women.

BACKGROUND/HYPOTHESIS: SMARTWOMAN™ was designed to develop and assess the feasibility of a smartphone app to control cardiovascular risk factors in vulnerable diabetic women. METHODS: Fourteen African-American women with diabetes and without known cardiovascular disease were enrolled. A weight-scale, glucometer, sphygmomanometer, and FitBit were synchronized to the smartphone, and text messaging was provided. Follow-up was 6 months. RESULTS: Patients were able to follow instructions for app use and device prompts. Weekly device reporting was 85% for blood glucose, 82.5% for daily steps, and 77% for systolic blood pressure. Patient engagement levels were 85% to 100% at 1 month and 50% to 78% at month 6. The majority reported text messages to be useful, easy to understand, and appropriate in frequency. The women indicated on the exit questionnaire that study participation increased their motivation and ability to take charge of their health. CONCLUSIONS: Use of a smartphone app to control cardiovascular risk factors appears feasible in a population of vulnerable indigent African-American diabetic women, resulted in increased patient satisfaction and positive reinforcement to healthy behaviors, and warrants a larger clinical outcome trial.

Antihypertensive medications and sexual function in women: baseline data from the SBP intervention trial (SPRINT).

OBJECTIVES: Hypertension is a risk factor for the development of cardiovascular and kidney disease, but treatment can substantially reduce risks. Many patients avoid antihypertensive medications because of fear of side-effects. Although associations between antihypertensives and sexual dysfunction in men have been documented, it remains unclear whether antihypertensives are associated with sexual dysfunction in women. We conducted a cross-sectional analysis of baseline data from women in the Systolic Blood Pressure Intervention Trial (SPRINT) to evaluate the relations among class of antihypertensive medication and the outcomes: sexual activity and sexual function. METHODS: SPRINT enrolled individuals 50 and older with hypertension at high risk for cardiovascular disease. A subset of participants completed questionnaires regarding quality of life, including sexual function. Antihypertensive class was determined by medications taken at baseline. RESULTS: Of 690 women in the quality of life subset of SPRINT, 183 (26.5%) were sexually active. There were no significant differences in sexual activity among women taking one or more antihypertensives and women not taking any. Women taking an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker had higher odds of sexual activity [odds ratio 1.66 (1.12-4.27), P = 0.011]. Among sexually active women, the prevalence of sexual dysfunction was high (52.5%). No class of medication was associated with sexual dysfunction in the multivariable model. CONCLUSION: Angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use was associated with higher odds of sexual activity. Although prevalence of sexual dysfunction was high, no single class of antihypertensive medication was associated with sexual dysfunction.

Comparing morbidities of testing with a new index: screening colonoscopy versus core-needle breast biopsy.

PURPOSE: Focusing on outcomes of care alone may be too restrictive. Patients can experience morbidity that is important to them from health care processes themselves. However, many processes, such as testing and screening, have been little evaluated. This study's purpose was to assess the construct validity of a new preference-based index, the Testing Morbidities Index (TMI), by comparing two common cancer-related procedures in prior publications: screening colonoscopy and core-needle breast biopsy. METHODS: Women evaluating their breast biopsies (n = 100) were compared with men and women who had undergone screening colonoscopy (n = 109) after both groups completed the TMI. The TMI addresses physical and mental or emotional quality of life affected by test-specific aspects occurring before, during, or after any test. It has 7 domains and survey items. TMI scores can be scaled in various ways, including multi-attribute value theory-based patient or societal preferences, where 0 = dead and 1.0 = full health, as used here. RESULTS: There was significantly greater morbidity from breast biopsy (mean, 0.84) than from screening colonoscopy (mean, 0.88) comparing overall TMI preference scores (P < .0001). Breast biopsy showed significantly worse morbidity (P = .005 to P < .0001) in most domains. Pain or discomfort before testing was worse for colonoscopy because of bowel preparation. The TMI showed no floor effect and an acceptable ceiling effect. CONCLUSIONS: The TMI provides the first objective evidence comparing the morbidity of one cancer-related testing procedure with another. The TMI may be useful in assessments of medical care processes informative to institutions and imaging departments, shared decision-making scenarios, and economic analyses.

Patient and societal value functions for the testing morbidities index.

BACKGROUND: We developed preference-based and summated scale scoring for the Testing Morbidities Index (TMI) classification, which addresses short-term effects on quality of life from diagnostic testing before, during, and after testing procedures. METHODS: The two TMI preference functions use multiattribute value techniques; one is patient-based and the other has a societal perspective, informed by 206 breast biopsy patients and 466 (societal) subjects. Because of a lack of standard short-term methods for this application, we used the visual analog scale (VAS). Waiting tradeoff (WTO) tolls provided an additional option for linear transformation of the TMI. We randomized participants to 1 of 3 surveys: The first derived weights for generic testing morbidity attributes and levels of severity with the VAS; a second developed VAS values and WTO tolls for linear transformation of the TMI to a "dead-healthy" scale; the third addressed initial validation in a specific test (breast biopsy). The initial validation included 188 patients and 425 community subjects. Direct VAS and WTO values were compared with the TMI. Alternative TMI scoring as a nonpreference summated scale was included, given evidence of construct and content validity. RESULTS: The patient model can use an additive function, whereas the societal model is multiplicative. Direct VAS and the VAS-scaled TMI were correlated across modeling groups (r = 0.45-0.62). Agreement was comparable to the value function validation of the Health Utilities Index 2. Mean absolute difference (MAD) calculations showed a range of 0.07-0.10 in patients and 0.11-0.17 in subjects. MAD for direct WTO tolls compared with the WTO-scaled TMI varied closely around 1 quality-adjusted life day. CONCLUSIONS: The TMI shows initial promise in measuring short-term testing-related health states.
