Engaging Stakeholders to Adapt an Evidence-Based Family Healthy Weight Program.

Childhood obesity is associated with negative physical and psychosocial outcomes, especially for children from low-income backgrounds. It is critical to adapt evidence-based family healthy weight programs to meet the needs of this population. The Framework for Reporting Adaptations and Modifications to Evidence-Based Interventions was used to describe the process of using qualitative data from community and intervention stakeholders, children with overweight or obesity from low-income backgrounds, and caregivers to guide adaptations to the JOIN for ME pediatric weight management intervention. Qualitative interviews were conducted with key community and intervention stakeholders (e.g., nurse care managers, prior JOIN for ME coaches; N = 21). Focus groups were conducted in both Spanish and English with children with overweight or obesity from low-income backgrounds (N = 35) and caregivers of children with overweight or obesity from low-income backgrounds (N = 71). Qualitative data analysis informed modifications including content adaptations to simplify and tailor materials, contextual adaptations to improve intervention engagement and framing, resource awareness, and modality of delivery, training adaptations, and implementation/scale-up activities to increase connections with community partners. The process of engaging multiple stakeholder perspectives to tailor an existing intervention can provide a model for future researchers to improve the potential disseminability of an intervention.

Obesity during childhood is related to a number of negative outcomes for youth, with children from low-income backgrounds at especially high risk for obesity and related negative outcomes. There is a pressing need for programs to address weight in children and families that meet the needs of families from low-income backgrounds. This study outlines adaptations made to an evidence-based family healthy weight program to increase the likelihood of dissemination in low-income communities. Interviews were conducted with community stakeholders, children with overweight or obesity from low-income backgrounds, and caregivers of children with overweight or obesity from low-income backgrounds. These interviews led to simplification and tailoring of curriculum materials, changes to framing of weight management, increased information about available resources, remote intervention delivery, and changes to scale-up activities.

Implementation of Mobile Teledermatology: Challenges and Opportunities.

Background: While teledermatology is well-established in the Department of Veterans Affairs (VA), its implementation is far from complete. To facilitate consultative teledermatology and extend its reach, VA introduced a mobile teledermatology application (app) at three VA sites. Methods: We evaluated the initial implementation process using a mixed-methods, multiple case study approach to assess organizational readiness for change (ORC), which included examining facilitators, barriers, and contextual factors that affected implementation. We conducted: (1) group interviews and bimonthly reports to understand site processes; (2) semistructured interviews and surveys of individual participants representing a range of implementation roles; and (3) a review of internal organizational documents. We identified themes from interviews using an iterative process, and computed an ORC score based on surveys. Results: Forty-three individuals participated in the study. Qualitative data from all sites, corroborated by survey data available from one site, revealed a high readiness for change with an ORC score of 4.2, where 5 = maximal readiness for change. Facilitators included support from leadership and clinical champions, active telehealth programs, and an understanding and appreciation of the program and the resources needed. At all sites, however, technical issues negatively affected adoption; these included a suboptimal information technology infrastructure, which led to the inoperability of the app at two sites, and technical inefficiencies related to users' unfamiliarity with new devices and inconsistent internet access. Conclusions: Although a strong commitment to change and a confidence to effect change existed, these alone were insufficient to surmount barriers to implementation effectiveness.

Implementing Teledermatology for Rural Veterans: An Evaluation Using the RE-AIM Framework.

Introduction: Few systematic evaluations of implementing teledermatology programs in large health care systems exist. We conducted a longitudinal evaluation of a U.S. Department of Veterans Affairs (VA) initiative to expand asynchronous consultative teledermatology services for rural veterans. Methods: The reach, effectiveness, adoption, implementation, and maintenance framework guided the evaluation, which included analysis of quantitative VA administrative data as well as an online survey completed by participating facilities. The first 2 years of the program were compared with the year before the start of funding. Results: Sixteen hub facilities expanded teledermatology's reach over the 2-year period, increasing the number of referral spoke sites, unique patients served, and teledermatology encounters. Effectiveness was reflected as teledermatology constituted an increasing fraction of dermatology activity and served more remotely located patients. Adoption through defined stages of implementation progressed as facilities engaged in a variety of strategies to enhance teledermatology implementation, and facilitators and barriers were identified. Program maintenance was assessed by Program Sustainability Index scores, which reflected the importance of executive support, and ongoing concerns about staffing and longitudinal funding. Discussion: Enabling hubs to create solutions that best fit their needs and culture likely increased reach and effectiveness. Important facilitators included organizational leadership and encouraging communication between stakeholders before and during the intervention. Conclusions: A systematic analysis of teledermatology implementation to serve rural sites in VA documented a high degree of implementation and sustainability as well as areas for improvement.

Patient-provided e-support in reduced intensity obesity treatment: The INSPIRE randomized controlled trial.

OBJECTIVE: There are two types of patient supporters, peers (two individuals initiating health behavior change who support one another) and mentors (a previously successful patient who supports incoming patients). Social comparison theory suggests that peers and mentors may elicit social comparison processes (patients may compare their progress to that of their peer/mentor), and these social comparisons could impact treatment outcomes. This randomized controlled trial is the first to examine the differential impact of peers and mentors on obesity treatment outcomes and social comparison processes when added to reduced intensity treatment. METHOD: Participants (N = 278) were randomly assigned to reduced intensity behavioral weight loss treatment alone (rBWL), rBWL plus peer e-support (rBWL + Peer), or rBWL plus mentor e-support (rBWL + Mentor). rBWL involved periodic group sessions that decreased over time; when group sessions decreased, intensity of peer/mentor e-support increased. Weight and social comparison processes were assessed throughout the 12-month intervention. RESULTS: There was a significant treatment effect; when group sessions became less frequent and peer/mentor e-support became more frequent, rBWL + Peer had significantly greater weight loss than rBWL alone, and rBWL + Mentor was not significantly different from the other two. Social comparison processes differed by treatment arm; rBWL + Peer participants tended to report more lateral social comparisons ("my weight loss progress is 'similar' to my peer's"), whereas rBWL + Mentor participants reported more upward comparisons ("my weight loss progress is 'worse than' my mentor's"). Upward comparisons were associated with poorer weight loss outcomes. CONCLUSIONS: Peer e-support may be an effective, low-cost, sustainable method for improving longer-term weight loss outcomes in reduced intensity obesity treatment.

Assessment of the Safety Risk of Dermatoscope Magnets in Patients With Cardiovascular Implanted Electronic Devices.

Importance: Cardiovascular implanted electronic devices (CIEDs) are susceptible to electromagnetic interference. Dermatologists regularly use devices containing magnets, including dermatoscopes and their attachments, which could pose a hazard to patients with CIEDs. Objective: To investigate the safety risk of magnets in dermatoscopes to patients with CIEDs. Design, Setting, and Participants: This cross-sectional observational study was conducted between January 1, 2018, and March 31, 2018, in a controlled laboratory setting. Two experiments were performed. In the first experiment (performed in the Dermatology Service at Memorial Sloan Kettering Cancer Center, New York), dermatoscopes that contain magnets were obtained from 3 manufacturers. Using a magnometer, the magnetic field strength of the dermatoscopes was measured over the magnet; at the faceplate; and at a distance of 0.5 cm, 1 cm and 15 cm away from the faceplate. In the second experiment (performed in the University Heart Center Zurich, Zurich, Switzerland), ex vivo measurements were conducted to determine how the dermatoscopes affected old-generation and new generation CIEDs (pacemakers and implantable defibrillators). Main Outcomes and Measures: Magnetic field strength as measured directly over the dermatoscope magnet; at the faceplate; and at distances of 0.5 cm, 1 cm, and 15 cm from the faceplate. Pacemaker and defibrillator operation when exposed to dermatoscopes. Results: After conducting 24 measurements, the magnetic field (measured in gauss [G]) strength varied between 24.26 G and 163.04 G over the dermatoscope magnet, between 2.22 G and 9.98 G at the dermatoscope faceplate, between 0.82 G and 2.4 G at a distance of 0.5 cm, and between 0.5 G and 1.04 G at a distance of 1 cm; it was 0 for all devices at a 15 cm distance. The field strength at the faceplate was found to be generally below the CIED industry standard safety threshold. None of the dermatoscopes in the ex vivo experiment exerted any demonstrable disruptions or changes to the CIEDs. Conclusions and Relevance: In real life, dermatoscope magnets likely present no measurable safety risk to patients with CIEDs. Using the polarized noncontact mode permits dermoscopy to be performed at least 0.5 cm from the skin surface, where the magnetic field strength was well below the 5-G safety threshold.

Biphasic effects of alcohol on delay and probability discounting.

Delay discounting and probability discounting are behavioral economic indices of impulsive and risky decision making that have been associated with addictive behavior, but the acute biphasic effects of alcohol on these decision-making processes are not well understood. This study sought to investigate the biphasic effects of alcohol on delay and probability discounting across the ascending and descending limbs of the breath alcohol concentration (BAC) curve, which are respectively characterized by the stimulant and sedative effects of alcohol. Delay and probability discounting were measured at four time points (Baseline, Ascending, Descending, and End point) across the BAC curve at two target alcohol doses (40 mg/dl and 80 mg/dl) in healthy adults (n = 23 and 27, for both doses, respectively). There was no significant effect of alcohol on delay discounting at either dose. Alcohol significantly affected probability discounting, such that reduced discounting for uncertain rewards was evident during the descending limb of the BAC curve at the lower dose (p < .05) and during both the ascending and descending limb of the BAC curve at the higher dose (p < .05). Thus, alcohol resulted in increased risky decision making, particularly during the descending limb, which is primarily characterized by the sedative effects of alcohol. These findings suggest that the biphasic effects of alcohol across the ascending and descending limbs of the BAC have differential effects on behavior related to decision-making for probabilistic, but not delayed, rewards. Parallels to and distinctions from previous findings are discussed.

A within-group design of nontreatment seeking 5-HTTLPR genotyped alcohol-dependent subjects receiving ondansetron and sertraline.

BACKGROUND: Serotonergic mechanisms are associated with the development of alcohol dependence (AD), however, studies evaluating serotonergic medications have produced conflicting results. One hypothesis suggests that differential response may be due to a functional polymorphism of the 5-HTTLPR promoter region of the serotonin re-uptake transporter (5-HTT). The L/L genotype is postulated to be associated with early onset alcoholism and the S/S or S/L genotypes associated with late onset alcoholism. The aim of this study was to match and mismatch L/L, S/S, or S/L genotypes with administration of ondansetron and sertraline. METHODS: Fifteen nontreatment seeking alcohol-dependent individuals were randomized to 1 of 2 counterbalanced arms to receive either 200 mg/d of sertraline or ondansetron 0.5 mg/d for 3 weeks followed by an alcohol self-administration experiment (ASAE), then received placebo for 3 weeks followed by a second ASAE. Participants then received the alternate drug for 2 weeks followed by a third ASAE. RESULTS: At the first ASAE compared to sertraline, ondansetron significantly improved drinking outcomes for the L/L genotype for the ASAE volume consumed (100% reduction based on between-subjects comparison, t = 2.35), and for drinks per drinking day during the 7 days prior to the ASAE (79% reduction and t = 4.34). Compared with ondansetron for S/S or S/L genotypes, outcomes at ASAE 1 for sertraline and S/S or S/L genotypes are opposite than hypothesized. Overall, subjects reduced drinking across their participation in the trial, as there appears to be an order effect. CONCLUSION: This study suggests that ondansetron may reduce alcohol consumption in alcohol-dependent individuals who have the L/L genotype as measured naturalistically and during the ASAE. By contrast there was no support that sertraline reduces alcohol use in individuals who have S/S or S/L genotypes. Evidence in the literature suggests that AD in some individuals may be influenced by a gene by socio-environmental interaction making pharmacological treatment with serotonergic drugs complex. Research must consider that typologies may predict successful treatment of AD in future trials.
