BACKGROUND Mobile health applications show vast potential in supporting patients and health care systems with the globally increasing prevalence and economic costs of non-communicable diseases. However, despite the availability of evidence-based mHealth apps, a substantial proportion of users does not adhere to them as intended and may consequently not receive treatment. Therefore, understanding factors that act as barriers or facilitators to adherence is a fundamental concern to prevent intervention dropouts and increase the effectiveness of digital health interventions. OBJECTIVE This review aims to identify intervention- and patient-related factors influencing the continued use of mHealth applications targeting non-communicable diseases (NCDs). We further derive quantified adherence scores for different health domains, which may help stakeholders plan, develop, and evaluate mHealth apps. METHODS A comprehensive systematic literature search (January 2007- December 2020) was conducted in MEDLINE, Embase, Web of Science, Scopus, and ACM Digital Library. Data on intended use, actual use, and factors influencing adherence were extracted. Intervention-related and patient-related factors with a positive or negative influence on adherence are presented separately for the health domains NCD-Self-Management, Mental Health, Substance Use, Nutrition, Physical Activity, Weight Loss, Multicomponent Lifestyle Interventions, Mindfulness, and other NCDs. Quantified adherence measures, calculated as the ratio between estimated intended and actual use, were derived for each study and compared with qualitative findings. RESULTS The literature search yielded 2862 potentially relevant articles, of which 99 were included as part of the inclusion criteria. Four intervention-related factors indicated positive effects on adherence across all health domains: (1) personalization or tailoring the content of the mHealth app to the individual needs of the user, (2) reminders in the form of individualized push notifications, (3) a user-friendly and technically stable app design, and (4) personal support complementary to the digital intervention. Social and gamification features were also identified as drivers of app adherence across several health domains. A wide variety of patient-related factors like user characteristics or user recruitment channels further affects adherence. Derived adherence scores of included mHealth apps averaged 56.0%. CONCLUSIONS This study contributes to the scarce scientific evidence on factors positively or negatively influencing adherence to mHealth apps and is the first to compare adherence relative to the intended use of various health domains quantitatively. As underlying studies mostly have a pilot character with short study durations, research on factors influencing adherence to mHealth apps is still limited. To facilitate future research on mHealth app adherence, researchers should clearly outline and justify the app's intended use, report objective data on actual use relative to the intended use, and ideally, provide long-term usage and retention data.

Abstract Recruitment and engagement of racial/ethnic minority older adults in clinical trials is crucial to expand implementation of evidence-based interventions for disability prevention. Public Health measures to counteract COVID-19 pandemic have increased the challenges on reaching this population. This study seeks to comprehensively evaluate a set of recruitment strategies to enroll Latino, Asian and African American older adults with symptoms of depression and anxiety during the first year of a randomized clinical trial. A partnership of three academic sites across the U.S. (NYC, MA and PR) involving several collaborations with community agencies recruited racial/ethnic minority older adults using different strategies involving bilingual interviewers calling from hospital research dataset and community agencies’ list of clients, referrals from primary care providers or psychotherapy waitlist. In this presentation we will report various recruitment and retention data including individual and organizational predictors of successful recruitment as well as challenges across all three sites.

The literature suggests that volunteering can be used to address social isolation and support patients with psychosis in the community. However, many expect in person meetings, requiring a greater effort of availability and commitment. There is therefore a need for more flexible, easily accessible support. Volunteering via smart-phone could be a useful intervention for people with psychosis. One patient and one volunteer have been matched for a duration of 12 weeks, and participants have been encouraged to communicate through a variety of communication methods (audio calls, video calls, text messages, WhatsApp messages and e-mails). The Phone Pal study aimed to investigate the feasibility of recruitment, participant retention, data collection procedures, intervention usage of the methods of communication and changes in outcome data. At baseline and follow-up outcome measures collected from patients and volunteers included their quality of life, physical activity, self-esteem and social comparison. Additional outcomes assessed patients' attachment, social contacts and symptoms; for volunteers, their social distance was evaluated. At follow-up both patients and volunteers rank their perception of their relationship with each other. This mixed method feasibility study has been conducted in two phases, the first stage evaluating a smaller sample of patients and volunteers recruited in London, and then a second phase with a larger sample of volunteers recruited from across the United Kingdom.Trial registration: ISRCTN17586238.

Abstract An assessment of the tritium (T) inventory in plasma facing components (PFC) during JET T & DT operations is presented based on the most comprehensive ex-situ fuel retention data set on JET PFCs from the 2015-2016 ILW3 operating period is presented. The global fuel retention is 4.19 x 1023 D atoms, 0.19% of injected fuel. The inner divertor remains the region of highest fuel retention (46.5%). The T inventory in PFCs at the end of JET operations is calculated as 7.48 x 1022 atoms and is informative for accountancy, clean-up efficacy and waste liability assessments. The T accumulation rate at the upper inner divertor during JET deuterium-tritium (DT) operations has been used to assess the requirements and frequency of operation of a new laser induced desorption diagnostic to be installed on JET for the final DT experiments in 2023.

Early alert systems (EAS) are an important technological tool to help manage and improve student retention. Data spanning 16,091 students over 156 weeks was collected from a regionally based university in Australia to explore various microeconometric approaches that establish links between EAS and student retention outcomes. Controlling for numerous confounding variables, significant relationships between the EAS and student retention were identified. Capturing dynamic relationships between the explanatory variables and the hazard of discontinuing provides new insight into understanding student retention factors. We concluded that survival models are the best methods of understanding student retention when temporal data is available.

Abstract Background COVID-19 has become a worldwide pandemic that brought changes in sociological, economic and health perspectives. The impact of the pandemic on health maintenance is not yet understood, but aspects of the lockdown are being assessed for their impact on society. Diabetes and HIV are diseases that require frequent follow-up to achieve outcomes. Changes to routines during the lockdown, such as physical activity, eating habits, and psychological burden, may result in complications for this patient population. Methods This is a multi-center, retrospective cohort study performed between October 2019 to October 2020 at two medical centers in Brooklyn, NY. All adult patients with diagnoses of diabetes and HIV were screened for inclusion. Exclusion criteria included pregnancy and long-term steroid use. Electronic medical records were reviewed to obtain demographic, laboratory data, and appointment retention data. The primary endpoint was the mean change in HbA1c (A1c) values before and after the pandemic. Endpoints were evaluated using paired T-tests and Wilcoxon Sign-Rank tests, where appropriate, and a repeated measures logistic regression model was used to analyze appointment retention rates. Results Baseline characteristics are summarized in Table 1. No significance was observed between baseline A1c values and those taken either up to 3 months (p= 0.862) or up to 6 months (p= 0.977) after the start of the pandemic, as shown in Table 2. Similarly, no difference was observed in HIV surrogate markers. A1c significantly decreased from between the 3-month and 6-month study dates, after the start of the pandemic (p= 0.022). Table 3 shows patients were more likely to fulfill a scheduled appointment during the pandemic with an odds ratio of 1.455 (95% CI, 1.119-1.891). Conclusion No significance was found in surrogate markers for health maintenance before and after the pandemic. Patients were more likely to keep an appointment after the start of the pandemic and A1c values significantly declined from 3 months to 6 months into the pandemic. Although COVID-19 did not appear to change overall health maintenance of T2DM within our population, our results imply that pandemic measures, such as telehealth appointments, positively affected appointment adherence, which is key to success in this population.

Abstract Background When use of a single antiseizure medication (ASM) fails to induce seizure remission, add-on therapy is justified. Perampanel (PER) is approved in Europe as adjunctive therapy for focal, focal to bilateral tonic-clonic seizures and generalized tonic-clonic seizures. Aim of the study was to establish whether PER is suitable for first add-on use. Methods A Delphi methodology was adopted to assess consensus on a list of 39 statements produced by an Expert Board of 5 epileptologists. Using an iterative process, statements were finalized by a Delphi Panel of 84 Italian pediatric and adult neurologists. Each statement was rated anonymously to determine level of agreement on a 9-point Likert scale. Consensus was established as agreement by at least 80% of the panelists. The relevance of each statement was also assessed on a 3-point scale. Results Consensus was achieved for 37 statements. Characteristics of PER considered to justify its use as first add-on include evidence of a positive impact on quality of life based on long term retention data, efficacy, tolerability, and ease of use; no worsening of cognitive functions and sleep quality; a low potential for drug interactions; a unique mechanism of action. Potential unfavorable factors are the need for a relatively slow dose titration; the potential occurrence of behavioral adverse effects; lack of information on safety when used in pregnancy; limited access to plasma PER levels. Conclusion Perampanel has many features which justify its use as a first add-on. Choice of an ASM as first add-on should be tailored to individual characteristics.

In this work, we conducted the following analysis of Ni/ZnO (20 nm)/n-type Si RRAM device with three different compliance currents (CCs). We compared I–V curves, including set, reset voltages, and resistance of LRS, HRS states for each CCs. For an accurate comparison of each case, statistical analysis is presented. In each case, the average value and the relative standard deviation (RSD) of resistance are calculated to analyze the characteristics of the distribution. The best variability is observed at higher CC (5 mA). In addition, we validated the non-volatile properties of the device using the retention data for each of the CCs. Based on this comparison, we proposed the most appropriate CC of the device operation. Also, a pulse was applied to measure the current waveform and demonstrate the regular operation of the device. Finally, the resistance of LRS and HRS states was measured by pulse. We statistically compared the measured pulse data with the DC data.
