Severe Asthma Standard-of-Care Background Medication Reduction With Benralizumab: ANDHI in Practice Substudy

Background: The phase IIIb, randomized, parallel-group, placebo-controlled ANDHI double-blind (DB) study extended understanding of the efficacy of benralizumab for patients with severe eosinophilic asthma. Patients from ANDHI DB could join the 56-week ANDHI in Practice (IP) single-arm, open-label extension substudy. Objective: Assess potential for standard-of-care background medication reductions while maintaining asthma control with benralizumab. Methods: Following ANDHI DB completion, eligible adults were enrolled in ANDHI IP. After an 8-week run-in with benralizumab, there were 5 visits to potentially reduce background asthma medications for patients achieving and maintaining protocol-defined asthma control with benralizumab. Main outcome measures for non-oral corticosteroid (OCS)-dependent patients were the proportions with at least 1 background medication reduction (ie, lower inhaled corticosteroid dose, background medication discontinuation) and the number of adapted Global Initiative for Asthma (GINA) step reductions at end of treatment (EOT). Main outcomes for OCS-dependent patients were reductions in daily OCS dosage and proportion achieving OCS dosage of 5 mg or lower at EOT. Results: For non-OCS-dependent patients, 53.3% (n = 208 of 390) achieved at least 1 background medication reduction, increasing to 72.6% (n = 130 of 179) for patients who maintained protocol-defined asthma control at EOT. A total of 41.9% (n = 163 of 389) achieved at least 1 adapted GINA step reduction, increasing to 61.8% (n = 110 of 178) for patients with protocol-defined EOT asthma control. At ANDHI IP baseline, OCS dosages were 5 mg or lower for 40.4% (n = 40 of 99) of OCS-dependent patients. Of OCS-dependent patients, 50.5% (n = 50 of 99) eliminated OCS and 74.7% (n = 74 of 99) achieved dosages of 5 mg or lower at EOT. Conclusions: These findings demonstrate benralizumab's ability to improve asthma control, thereby allowing background medication reduction

Optimism/pessimism and health-related quality of life during pregnancy across three continents: a matched cohort study in China, Ghana, and the United States

Abstract Background Little is known about how optimism/pessimism and health-related quality of life compare across cultures. Methods Three samples of pregnant women in their final trimester were recruited from China, Ghana, and the United States (U.S.). Participants completed a survey that included the Life Orientation Test - Revised (LOT-R, an optimism/pessimism measure), the Short Form 12 (SF-12, a quality of life measure), and questions addressing health and demographic factors. A three-country set was created for analysis by matching women on age, gestational age at enrollment, and number of previous pregnancies. Anovas with post-hoc pairwise comparisons were used to compare results across the cohorts. Multivariate regression analysis was used to create a model to identify those variables most strongly associated with optimism/pessimism. Results LOT-R scores varied significantly across cultures in these samples, with Ghanaian pregnant women being the most optimistic and least pessimistic and Chinese pregnant women being the least optimistic overall and the least pessimistic in subscale analysis. Four key variables predicted approximately 20% of the variance in overall optimism scores: country of origin (p = .006), working for money (p = .05); level of education (p = .002), and ever being treated for emotional issues with medication (p < .001). Quality of life scores also varied by country in these samples, with the most pronounced difference occurring in the vitality measure. U.S. pregnant women reported far lower vitality scores than both Chinese and Ghanaian pregnant women in our sample. Conclusion This research raises important questions regarding what it is about country of origin that so strongly influences optimism/pessimism among pregnant women. Further research is warranted exploring underlying conceptualization of optimism/pessimism and health related quality of life across countries.http://deepblue.lib.umich.edu/bitstream/2027.42/112354/1/12884_2009_Article_237.pd

Assessment of left atrial volume in resistant hypertension by cardiac magnetic resonance imaging

Introduction: Increased left atrial (LA) volumes are associated with impaired diastolic properties of the left ventricle (LV) and have been shown to predict cardiovascular events in a wide spectrum of patients. A relation between LA volume and aldosterone has been reported in idiopathic dilated cardiomyopathy, but this relationship has not been evaluated in resistant hypertensive subjects. Hypothesis: We hypothesized that patients with elevated plasma aldosterone concentration (PAC) have greater LA volumes. We compared LA volumes in normal subjects and mildly hypertensive patients (Controls) and patients with resistant hypertension. Methods: 71 patients (55 resistant hypertensive (51% male, age 57±12 y) and 16 Controls (62% men, age 54±11 y, p=ns) were studied. Clinic blood pressure (BP), plasma levels of B-type natriuretic peptide (BNP), PAC, plasma renin activity (PRA), serum cortisol, and 24 hour urinary aldosterone and sodium excretion were determined. Cardiac magnetic resonance imaging was performed in all patients and LA volumes were measured using a biplane length-area method and indexed for the body surface area. Results: Results are summarized in the Table. Resistant hypertensives had significantly higher systolic and diastolic BP compared to Controls. There was a trend towards higher PAC in hypertensives that did not reach statistical significance. BNP levels also were not different between the groups but we found a relationship between BNP and LA volume index (r=0.43, p=0.003). Hypertensives also exhibited increased LV mass and LA volume index compared to Controls. No relation between LA volume index and PAC was found. PRA, cortisol, and 24 hour urinary aldosterone and sodium excretion also had no relation to LA volume index. Conclusions: LA volume index is higher in resistant hypertension and shows positive correlation with BNP levels in all subjects but is not related to PAC in either the Control or Resistant hypertension groups

Rapid reversal of left ventricular hypertrophy and intracardiac volume overload in patients with resistant hypertension and hyperaldosteronism: A prospective clinical study

We have shown previously that patients with resistant hypertension and hyperaldosteronism have increased brain natriuretic peptide suggestive of increased intravascular volume. In the present study, we tested the hypothesis that hyperaldosteronism contributes to cardiac volume overload. Thirty-seven resistant hypertensive patients with hyperaldosteronism (urinary aldosterone ≥12 μg/24 hours and plasma renin activity ≤1.0 ng/mL per hour) and 71 patients with normal aldosterone status were studied. Both groups had similar blood pressure and left ventricular mass, whereas left and right ventricular end-diastolic volumes measured by cardiac MRI were greater in high versus normal aldosterone subjects (

Approach to High Volume Enrollment in Clinical Research: Experiences from an All of Us Research Program Site

Clinical trials and cohort studies are required to meet target recruitment of study participants within stipulated timelines, especially when the priority is to include populations traditionally unrepresented in biomedical research. By the third quarter of 2019, the University of Arizona-Banner Health Provider Organization (UA-Banner HPO) has enrolled > 30,000 core participants into theAll of UsResearch Program (AoURP), the research cohort of the Precision Medicine Initiative. The majority of enrolled participants meet the criteria for individuals under-represented in biomedical research. The enrollment goals were calculated based on a target of 20,000 as set by the National Institutes of Health and our health provider organization achieved enrollment numbers between 17% and 86% above the targeted daily enrollment. We evaluated enrollment methods and challenges to enrollments encountered by the UA-Banner Health Provider Organization into theAoURP. Challenges to enrollment centered around the need for high-touch engagement methods, time investment necessary for stakeholder inclusion, and the use of purely digital enrollment methods especially in populations under-represented in biomedical research. These challenges occurred at the level of the individual, provider, institutions, and community, and cumulatively impacted participant enrollment. Successful strategies for engagement and enrollment leveraged provider partners as advocates for the program. For high-volume enrollment in clinical research, it is important to engage leaders in the healthcare setting, patient providers, and tailor engagement and enrollment to potential participant needs. We emphasize the need for precision engagement and enrollment methods tailored to individual needs.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
