Abstract Objectives We examined whether a diet personalized to reduce postprandial glycemic response (PPGR) to foods increases weight loss self-efficacy. Methods The Personal Diet Study is an ongoing clinical trial that aims to compare two weight loss diets: a one-size-fits-all, calorie-restricted, low-fat diet (Standardized) versus a diet having the same calorie restriction but utilizing a machine learning algorithm to predict and reduce PPGR (Personalized). Both groups receive the same behavioral counseling to enhance weight loss self-efficacy. Both groups self-monitor dietary intake using a mobile app, with Standardized receiving real-time feedback on calories and macronutrient distribution, and Personalized receiving real time feedback on calories, macronutrient distribution, and predicted PPGR. We examined changes in self-efficacy between baseline and 3 mos, using the 20-item Weight Efficacy Lifestyle questionnaire (WEL). Linear mixed models were used to analyze differences, adjusting for age, gender, and race. Results The analyses included the first 75 participants to complete 3-mos assessments (41 Personalized and 34 Standardized). The majority of the participants were white (69.3%), female (61.3%), with a mean age of 61.7 years (SD = 9.9) and BMI of 33.4 kg/m2 (SD = 4.8). At baseline, WEL scores were similar between the 2 groups [Standardized WEL: 118.8 (SD = 27.6); Personalized WEL: 124.9 (SD = 29.5), P = 0.47]. At 3 mos, the WEL score was significantly improved in both groups [16.0 (SD = 4.1) in the Standardized group (P < 0.001) and 7.4 (SD = 3.7) in the Personalized group (P = 0.048)], but the between group difference was not significant (P = 0.12). Conclusions Personalized feedback on predicted PPGRs does not appear to enhance weight loss self-efficacy at 3 mos. The lack of significance may be related to the short follow-up period in these preliminary analyses, the small sample accrued to date, or the fact that WEL is designed to assess confidence in various situations (e.g., depressed, anxious) that may not be impacted by personalization. These analyses will be replicated with a larger sample using data obtained through the 6-mos follow-up. New self-efficacy measures may be required to assess the impact of personalized dietary counseling. Funding Sources This research was supported by the American Heart Association.

AbstractCaffeine is widely used to promote alertness and cognitive performance under challenging conditions, such as sleep loss. Non-digestive modes of delivery typically reduce variability of its effect. In a placebo-controlled, 50-h total sleep deprivation (TSD) protocol we administered four 200 mg doses of caffeine-infused chewing-gum during night-time circadian trough and monitored participants' drowsiness during task performance with infra-red oculography. In addition to the expected reduction of sleepiness, caffeine was found to disrupt its degrading impact on performance errors in tasks ranging from standard cognitive tests to simulated driving. Real-time drowsiness data showed that caffeine produced only a modest reduction in sleepiness (compared to our placebo group) but substantial performance gains in vigilance and procedural decisions, that were largely independent of the actual alertness dynamics achieved. The magnitude of this disrupting effect was greater for more complex cognitive tasks.

Abstract Cannabis is one of the most commonly used substances in Canada with 15% of Canadians reporting use in 2019. There is emerging evidence that cannabis is linked to an impact on the developing brain in utero and adverse outcomes in infants, children, and adolescents. The impact of cannabis during breastfeeding has been limited by studies with small sample sizes, follow-up limited to 1 year and the challenge of separating prenatal exposure from that during breastfeeding. In the absence of high-quality evidence, health care providers need to continue to engage women in conversation about the potential concerns related to breastfeeding and cannabis use.

Abstract Background People with multiple sclerosis (MS) often experience fatigue, which is aggravated by inactivity. Identifying mediators of changes in physical activity (PA) and fatigue self-management (FSM) behaviors could optimize future interventions that reduce the impact of MS fatigue. Purpose To examine the effects of telephone-delivered interventions on Social Cognitive Theory constructs and test whether these constructs mediated secondary outcomes of PA and FSM behaviors. Methods Participants with MS (n = 208; Mean age = 52.1; Female = 84.6%) were randomized into contact–control intervention (CC), PA-only intervention, and PA+FSM intervention. Step count (Actigraphy) and FSM behaviors as well as self-efficacy, outcome expectations, and goal setting for PA and FSM were measured at baseline, post-test (12 weeks), and follow-up (24 weeks). Path analyses using bias-corrected bootstrapped 95% confidence intervals (CI) determined whether constructs at post-test mediated behaviors at follow-up when adjusting for baseline measures. Results Path analysis indicated that PA-only (β = 0.50, p < .001) and PA+FSM interventions (β = 0.42, p < .010) had an effect on goal setting for PA, and that PA + FSM intervention had an effect on self-efficacy for FSM (β = 0.48, p = .011) and outcome expectations for FSM (β = 0.42, p = .029). Goal setting for PA at post-test mediated the effects of PA-only (β = 159.45, CI = 5.399, 371.996) and PA + FSM interventions (β = 133.17, CI = 3.104, 355.349) on step count at follow-up. Outcome expectations for FSM at post-test mediated the effects of PA + FSM intervention on FSM behaviors at follow-up (β = 0.02, CI = 0.001, 0.058). Conclusions Goal setting for PA and outcome expectations for FSM may be important constructs to target in telephone-delivered interventions designed to reduce the impact of MS fatigue.

AbstractIntroduction: Data on long-term patterns of weight change in relation to the development of metabolic syndrome (MetS) are scarce. The aim of the study was to evaluate the impact of weight change on the risk of MetS in men. Material and Methods: Prospective longitudinal observation (17.9 ± 8.1 years) of apparently healthy 324 men aged 18–64 years. Metabolic risk was assessed in weight gain (⩾ 2.5 kg), stable weight (> −2.5 kg and < 2.5 kg) and weight loss (⩽ −2.5 kg) groups. Adjusted relative risk (RR) of MetS was analyzed using multivariate logistic regression. Results: The prevalence of MetS over follow-up was 22.5%. There was a strong relationship between weight gain and worsening of MetS components among baseline overweight men. Long-term increase in weight was most strongly related with the risk of abdominal obesity (RR=7.26; 95% CI 2.98–18.98), regardless of baseline body mass index (BMI). Weight loss was protective against most metabolic disorders. Leisure-time physical activity (LTPA) with energy expenditure > 2000 metabolic equivalent/min/week was associated with a significantly lower risk of MetS. Conclusions: Reducing weight among overweight and maintaining stable weight among normal-weight men lower the risk of MetS. High LTPA level may additionally decrease the metabolic risk regardless of BMI.

The increasing prevalence of overweight and obesity in humans is a growing public health concern in the United States. Concomitants include poor health behaviors and reduced psychological well-being. Preliminary evidence suggests yoga and treatment paradigms incorporating mindfulness, self-compassion (SC), acceptance, non-dieting, and intuitive eating may improve these ancillary correlates, which may promote long-term weight loss. Methods: We explored the impact of a 5-day residential weight loss program, which was multifaceted and based on Kripalu yoga, on health behaviors, weight loss, and psychological well-being in overweight/obese individuals. Thirty-seven overweight/obese program participants (age 32-65, BMI&lt;25) completed validated mind-fulness, SC, lifestyle behavior, and mood questionnaires at baseline, post-program, and 3-month follow-up and reported their weight 1 year after program completion. Results: Significant improvements in nutrition behaviors, SC, mindfulness, stress management, and spiritual growth were observed immediately post-program (n = 31, 84% retention), with medium to large effect sizes. At 3-month follow-up (n = 18, 49% retention), most changes persisted. Physical activity and mood disturbance had improved significantly post-program but failed to reach significance at 3-month follow-up. Self-report weight loss at 1 year (n = 19, 51% retention) was significant. Conclusion: These findings suggest a Kripalu yoga-based, residential weight loss program may foster psychological well-being, improved nutrition behaviors, and weight loss. Given the exploratory nature of this investigation, more rigorous work in this area is warranted.

e20633 Background: Cancer patient (pt) participation in clinical trials (CT) is low. Little is known about the beliefs and attitudes of health care workers (HCW) and how they impact intention to discuss CT with pts. The overall goal of this project was to develop a conceptual model to guide future interventions to enhance communication about CT between HCW and cancer pts. Methods: Two email surveys of non-physician HCW at an NCI-designated comprehensive cancer center were conducted. The first was sent to a random sample of 150 HCW. The second was sent to 80 who completed the first survey. Based on our prior work (Eads et al. ASCO 2011) and Ajzen’s Theory of Planned Behavior, domains of the first included CT knowledge (19 items, agree/disagree) and attitudes (27 items, 5-point Likert); the second included normative beliefs about institutional attitudes toward CT (6 items, 5-point Likert), self-efficacy about engaging in discussion about CT (14 items, 5-point Likert), and intention to discuss CT with pts (4 items, 7-point Likert). Results: 41 HCW completed both anonymous surveys; 27 could be matched by demographics. Median age of matched respondents was 44.3 yrs (range 24-63), 26 female, 22 caucasian, 9 nurses. Overall, CT knowledge was high (median 17/19 items correct). There were strong associations between attitudes and self-efficacy (Spearman r=-0.425, p=0.03), as well as perceived normative beliefs and self-efficacy (r=0.651, p=0.0002). These associations were strong amongst nurses (r=-0.818, p=0.007 and r=0.656, p=0.05, respectively), with a particularly strong correlation between self-efficacy and intention to discuss clinical trials with pts (r=0.891, p=0.001). Conclusions: In spite of a small sample size, these pilot data strongly support a behavioral framework to understand and address the impact of HCW attitudes and beliefs about CT on discussions of CT with pts. Insofar as HCW (especially nurses) have substantial pt contact, and serve as a resource for pts regarding treatment decisions, educational interventions to address HCW barriers to discussing CT with pts (i.e. attitudes, beliefs, and self-efficacy) could positively impact pt attitudes and improve decision making.

124 Background: Appetite and weight loss are common in patients with advanced cancer and specialized cachexia clinics have been established to address these symptoms. Given the association between anorexia/cachexia and other adverse symptoms, these patients may also benefit from specialty level palliative care (PC). However, referral to outpatient specialty level PC is often delayed or does not occur. We sought to examine the prevalence of other factors associated with appetite and weight loss in patients with advanced cancer and the impact of a specialized cachexia clinic on identification and treatment of other PC needs. Methods: The records of patients referred by their Oncologist to the cachexia clinic of a cancer center from August 2016 to June 2017 were reviewed retrospectively. Subjects who had been referred to PC by their Oncologist were excluded. Patients had been assessed for symptom burden using the Edmonton Symptom Assessment Scale (ESAS-r). Patients identified with PC needs had been referred to the PC clinic for follow-up within 30 days after cachexia clinic consultation. Results: Thirty subjects were evaluated in the cachexia clinic (average age 68 years; 63% female). The predominant diagnosis was lung cancer (70%). An average of 6 symptoms per patient were in the moderate to severe range on ESAS, excluding appetite. Depression, fatigue and pain were most common. The average cachexia clinic total ESAS score was 51.61. Only 17% of patients had completed advance directives. Ninety-three % of patients were referred to PC and 68% were seen. The average number of PC visits was 2.79. Within the PC clinic, advance directive completion increased to 37%, goals of care discussion occurred with 50% and 17% received hospice referrals. At the most recent follow-up in the PC clinic, the average total ESAS score had decreased by 11.44 (22%) and all ESAS item scores were improved on average. Conclusions: The cachexia clinic proved a useful means to identify other PC needs and achieve effective PC referrals. We suggest this is proof of concept that specialty clinics can be a meaningful way to achieve an earlier entry point to comprehensive PC in patients who were not previously referred by their Oncologists.

BACKGROUND New technologies can promote knowledge of HIV infection among patients suffering from this disease. Older patients with HIV infection represent an increasingly large group that could benefit from the use of specific apps. OBJECTIVE The aim of the study was to observe the acceptability and use of a mobile app on HIV infection in patients at least 60 years old and offer them the possibility of anonymously establishing contact with their peers. METHODS A series of clinical and psychosocial parameters were studied in 30 HIV-infected patients of over 60 years. The patients must be at least 60 years old, with a follow-up in the outpatient clinic for at least 1 year and without pathologies that limit his or her life expectancy to less than a year. They must know how to read and write. To be part of the group assigned to the app, they had to have their own smartphone and confirm that they were connected to the internet from that device. Overall, 15 of them were randomized to use an app and 15 were in the control group. All tests were repeated after 6 months. RESULTS The median age of patients was 66.5 years. Among them, 29 patients had an undetectable viral load at baseline. The median number of comorbid diseases was 2. Overall, 11 of them lived with their partners and 19 lived alone. They spent an average of 5 hours a day sitting down, and 56% (17/30) of them referred high physical activity. They scored 4 out of 5 for general quality of life perception. Moreover, 80% (24/30) presented high adherence to their treatment, and the average number of concomitant medications was 5. In the 6-min walking test, they covered a distance of 400 meters, and 3 of them desaturated during the test. The 15 patients made frequent use of the app, with 2407 sessions and an average of 7 min and 56 seconds time of use with a total of 13,143 screen views. During the 6 months of the trial, 3 non-AIDS events took place. There were no significant modifications to body mass index, blood pressure measurements, lipid profile, or immuno-virology information data. There were no differences in the questionnaire scores for perception of quality of life, confessed physical activity, or antiretroviral treatment (ART) and non-ART treatment adherence. CONCLUSIONS Significant differences between studied parameters were not objectified in these patients, possibly because this trial has significant limitations, such as a small sample size and only a brief follow-up period. However, patients did use the app frequently, making this a possible intervention to be proposed in future subsequent studies.
