Applying the COM-B model to creation of an IT-enabled health coaching and resource linkage program for low-income Latina moms with recent gestational diabetes: the STAR MAMA program.

BACKGROUND:One of the fastest growing risk groups for early onset of diabetes is women with a recent pregnancy complicated by gestational diabetes, and for this group, Latinas are the largest at-risk group in the USA. Although evidence-based interventions, such as the Diabetes Prevention Program (DPP), which focuses on low-cost changes in eating, physical activity and weight management can lower diabetes risk and delay onset, these programs have yet to be tailored to postpartum Latina women. This study aims to tailor a IT-enabled health communication program to promote DPP-concordant behavior change among postpartum Latina women with recent gestational diabetes. The COM-B model (incorporating Capability, Opportunity, and Motivational behavioral barriers and enablers) and the Behavior Change Wheel (BCW) framework, convey a theoretically based approach for intervention development. We combined a health literacy-tailored health IT tool for reaching ethnic minority patients with diabetes with a BCW-based approach to develop a health coaching intervention targeted to postpartum Latina women with recent gestational diabetes. Current evidence, four focus groups (n = 22 participants), and input from a Regional Consortium of health care providers, diabetes experts, and health literacy practitioners informed the intervention development. Thematic analysis of focus group data used the COM-B model to determine content. Relevant cultural, theoretical, and technological components that underpin the design and development of the intervention were selected using the BCW framework. RESULTS:STAR MAMA delivers DPP content in Spanish and English using health communication strategies to: (1) validate the emotions and experiences postpartum women struggle with; (2) encourage integration of prevention strategies into family life through mothers becoming intergenerational custodians of health; and (3) increase social and material supports through referral to social networks, health coaches, and community resources. Feasibility, acceptability, and health-related outcomes (weight loss, physical activity, consumption of healthy foods, breastfeeding, and glucose screening) will be evaluated at 9 months postpartum using a randomized controlled trial design. CONCLUSIONS:STAR MAMA provides a DPP-based intervention that integrates theory-based design steps. Through systematic use of behavioral theory to inform intervention development, STAR MAMA may represent a strategy to develop health IT intervention tools to meet the needs of diverse populations.

Polarized Secretion of Interleukin (IL)-6 and IL-8 by Human Airway Epithelia 16HBE14o- Cells in Response to Cationic Polypeptide Challenge

BACKGROUND: The airway epithelium participates in asthmatic inflammation in many ways. Target cells of the epithelium can respond to a variety of inflammatory mediators and cytokines. Damage to the surface epithelium occurs following the secretion of eosinophil-derived, highly toxic cationic proteins. Moreover, the surface epithelium itself is responsible for the synthesis and release of cytokines that cause the selective recruitment, retention, and accumulation of various inflammatory cells. To mimic the damage seen during asthmatic inflammation, the bronchial epithelium can be challenged with highly charged cationic polypeptides such as poly-L-arginine. METHODOLOGY/PRINCIPAL FINDINGS: In this study, human bronchial epithelial cells, 16HBE14o- cells, were "chemically injured" by exposing them to poly-l-arginine as a surrogate of the eosinophil cationic protein. Cytokine antibody array data showed that seven inflammatory mediators were elevated out of the 40 tested, including marked elevation in interleukin (IL)-6 and IL-8 secretion. IL-6 and IL-8 mRNA expression levels were elevated as measured with real-time PCR. Cell culture supernatants from apical and basolateral compartments were collected, and the IL-6 and IL-8 production was quantified with ELISA. IL-6 and IL-8 secretion by 16HBE14o- epithelia into the apical compartment was significantly higher than that from the basolateral compartment. Using specific inhibitors, the production of IL-6 and IL-8 was found to be dependent on p38 MAPK, ERK1/2 MAPK, and NF-kappaB pathways. CONCLUSIONS/SIGNIFICANCE: The results clearly demonstrate that damage to the bronchial epithelia by poly-L-arginine stimulates polarized IL-6 and IL-8 secretion. This apically directed secretion of cytokines may play an important role in orchestrating epithelial cell responses to inflammation

The research on endothelial function in women and men at risk for cardiovascular disease (REWARD) study: methodology

Background Endothelial function has been shown to be a highly sensitive marker for the overall cardiovascular risk of an individual. Furthermore, there is evidence of important sex differences in endothelial function that may underlie the differential presentation of cardiovascular disease (CVD) in women relative to men. As such, measuring endothelial function may have sex-specific prognostic value for the prediction of CVD events, thus improving risk stratification for the overall prediction of CVD in both men and women. The primary objective of this study is to assess the clinical utility of the forearm hyperaemic reactivity (FHR) test (a proxy measure of endothelial function) for the prediction of CVD events in men vs. women using a novel, noninvasive nuclear medicine -based approach. It is hypothesised that: 1) endothelial dysfunction will be a significant predictor of 5-year CVD events independent of baseline stress test results, clinical, demographic, and psychological variables in both men and women; and 2) endothelial dysfunction will be a better predictor of 5-year CVD events in women compared to men. Methods/Design A total of 1972 patients (812 men and 1160 women) undergoing a dipyridamole stress testing were recruited. Medical history, CVD risk factors, health behaviours, psychological status, and gender identity were assessed via structured interview or self-report questionnaires at baseline. In addition, FHR was assessed, as well as levels of sex hormones via blood draw. Patients will be followed for 5 years to assess major CVD events (cardiac mortality, non-fatal MI, revascularization procedures, and cerebrovascular events). Discussion This is the first study to determine the extent and nature of any sex differences in the ability of endothelial function to predict CVD events. We believe the results of this study will provide data that will better inform the choice of diagnostic tests in men and women and bring the quality of risk stratification in women on par with that of men

The Diverse Implementation of Geriatrics-Orthopedics Comanagement Programs in the United States.

BackgroundMany health systems are establishing geriatrics-orthopedics (Geri-Ortho) comanagement programs; however, there is paucity of published information on existing programs' variations in clinical operations, structure, and reported implementation challenges and perceived successes.ObjectiveOur objective was to obtain detailed information about the variety of existing Geri-Ortho comanagement programs in the United States.Design/particpantsWe conducted a cross-sectional survey of 44 existing Geri-Ortho comanagement programs, with 23 (52%) of programs responding.MeasurementQuantitative questions were used to assess operational, staffing, and financial structures; and qualitative questions were used to identify reported challenges and perceived successes of implementation.ResultsPrograms self-identified as urban (n = 23), academic (n = 20), or nonprofit (n = 22) and as having a level I trauma center (n = 17). Most programs (n = 18) were funded fully by the institution. Fourteen programs used geriatricians, and nine used medicine/hospitalists as the supporting clinical service, whereas approximately half (n = 11) used these services in a true comanagement model. Six universal themes were identified as necessary for program implementation. The most commonly described successes perceived by all respondents were improvements in clinical outcomes and better interdisciplinary relationships. Reported challenges included difficulty in interdisciplinary geriatrics education, difficulty in adherence to protocols, and lack of funding for staffing.ConclusionsThere are diverse types of Geri-Ortho comanagement programs in the United States, although universal elements exist. Many had similar challenges in implementation, and further studies are needed to determine which implementation elements are critical to clinical and financial outcomes.

Aiming for a shorter time to diagnosis: pediatric eosinophilic esophagitis in British Columbia

Longer time to diagnosis for patients with eosinophilic esophagitis can lead to adverse patient outcomes, but the length of diagnostic delay has not been quantified for patients with eosinophilic esophagitis in Canada. Our study defines the time to diagnosis (TTD) for pediatric patients with eosinophilic esophagitis in British Columbia and identifies factors that predict increased time to diagnosis. The median TTD was 21 months (1.75 years; IQR = 7, 45) with a median age at EoE diagnosis of 105 months (8.75 years; IQR = 44, 156). Caucasians experienced significantly longer TTD compared to other ethnicities (24 months (IQR = 7, 52) and 12 months (IQR = 4.5, 23) respectively, p = 0.008). Caucasian ethnicity (p = 0.037) and older age at the time of diagnosis (p = 0.006) predicted increased TTD. Our model explained 7.9% (Adjusted R² = 0.079) of the total variance for our cohort.Medicine, Faculty ofOther UBCNon UBCAllergy and Immunology, Division ofGastroenterology, Division ofMedicine, Department ofPediatrics, Department ofReviewedFacult
