BackgroundThis paper describes the research protocol for a randomized controlled trial of a multimodal mobile sleep intervention for heavy-drinking young adults. Young adults report the highest rates of heavy, risky alcohol consumption and are a priority population for alcohol prevention and intervention efforts. Alcohol strategies that leverage other health concerns and use technology may offer an innovative solution. Poor sleep is common among young adults and is a risk factor for developing an alcohol use disorder. Moreover, young adults are interested in information to help them sleep better, and behavioral sleep interventions address alcohol use as a standard practice. ObjectiveThe primary aim of this study is to assess the effectiveness of a 2-week multimodal mobile sleep intervention for reducing drinks consumed per week among heavy-drinking young adults. We will explore the effects on alcohol-related consequences, assessing quantitative and qualitative sleep characteristics as secondary aims. The study’s goals are to identify the optimal combination of sleep intervention components for improving drinking outcomes, the feasibility and acceptability of these components, and the potential mechanisms by which these components may promote alcohol behavior change. MethodsYoung adults (aged 18-25 years) who report recent heavy drinking will be randomly assigned to one of three conditions: mobile sleep hygiene advice (n=30), mobile sleep hygiene advice and sleep and alcohol diary self-monitoring (n=30), or mobile sleep hygiene advice, sleep and alcohol diary self-monitoring, and sleep and alcohol data feedback (n=60). For the feedback component, participants will complete two web-based sessions with a health coach during which they will receive summaries of their sleep and alcohol data, and the potential association between them along with brief advice tailored to their data. All participants will wear sleep and alcohol biosensors daily for 2 weeks for objective assessments of these outcomes. ResultsThe study was funded by the National Institutes of Health in May 2018. Recruitment began in December 2018 and will be concluded in Spring 2021. As of February 4, 2021, we have enrolled 110 participants. ConclusionsUltimately, this research could result in an efficacious, low-cost intervention with broad population reach through the use of technology. In addition, this intervention may substantially impact public health by reducing alcohol use disorder risk at a crucial developmental stage.

BackgroundNovel alcohol prevention strategies are needed for heavy-drinking young adults. Sleep problems are common among young adults who drink heavily and are a risk factor for developing an alcohol use disorder (AUD). Young adults, interested in the connection between sleep and alcohol, are open to getting help with their sleep. Therefore, sleep interventions may offer an innovative solution. This study evaluates social media advertising for reaching young adults and recruiting them for a new alcohol prevention program focused on sleep. ObjectiveThis study aims to evaluate the effectiveness and cost of using Facebook, Instagram, and Snapchat advertising to reach young adults who drink heavily for a sleep intervention; characterize responders’ sleep, alcohol use, and related concerns and interests; and identify the most appealing advertising content. MethodsIn study 1, advertisements targeting young adults with sleep concerns, heavy alcohol use, or interest in participating in a sleep program ran over 3 months. Advertisements directed volunteers to a brief web-based survey to determine initial sleep program eligibility and characterize the concerns or interests that attracted them to click the advertisement. In study 2, three advertisements ran simultaneously for 2 days to enable us to compare the effectiveness of specific advertising themes. ResultsIn study 1, advertisements generated 13,638 clicks, 909 surveys, and 27 enrolled volunteers in 3 months across the social media platforms. Fees averaged US $0.27 per click, US $3.99 per completed survey, US $11.43 per volunteer meeting initial screening eligibility, and US $106.59 per study enrollee. On average, those who completed the web-based survey were 21.1 (SD 2.3) years of age, and 69.4% (631/909) were female. Most reported sleep concerns (725/909, 79.8%) and an interest in the connection between sleep and alcohol use (547/909, 60.2%), but few had drinking concerns (49/909, 5.4%). About one-third (317/909, 34.9%) were identified as being at risk for developing an AUD based on a validated alcohol screener. Among this subsample, 8.5% (27/317) met the final criteria and were enrolled in the trial. Some volunteers also referred additional volunteers by word of mouth. In study 2, advertisements targeting sleep yielded a higher response rate than advertisements targeting alcohol use (0.91% vs 0.56% click rate, respectively; P

BACKGROUND: Earlier and more severe onset of chronic health conditions contributes to the increased risk of premature death among adults experiencing homelessness. Trimorbidity, a subset of multimorbidity representing overlap of physical health, mental health, and substance use conditions, disproportionately impacts adults experiencing homelessness. We know of no longitudinal data comparing trimorbidity trends among adults experiencing homelessness. OBJECTIVE: To characterize 19-year trimorbidity trends among adults experiencing homelessness. RESEARCH DESIGN: Repeated longitudinal, statewide survey administered every 3 years. SUBJECTS: Adults living throughout Minnesota experiencing homelessness. MEASURES: Reported diagnoses of chronic health conditions within 3 categories: physical health conditions (hypertension, heart disease, asthma, diabetes); mental health conditions (depression, posttraumatic stress disorder, bipolar disorder, schizophrenia/other paranoid, and delusional disorders); and substance use conditions (alcohol and illicit substances). RESULTS: A total of 25,552 surveys were completed by adults at 3-year intervals in a total of 7 waves. Participants reported increasing frequency and duration of homelessness, and more nights slept outside/in a car. 77.3% of adults experiencing homelessness in 2018 had one or more chronic health condition in any domain. From 2000 to 2018, bimorbidity and trimorbidity surpassed morbidity within a single domain. This was driven by increases in mental health conditions. In 2018, 31.7% of participants reported bimorbidity and 16.3% of adults reported trimorbidity. CONCLUSIONS: Adults experiencing homelessness bear a substantial and growing burden of bimorbidity and trimorbidity. Ensuring accessible, high quality care that includes robust services that can address all 3 categories of health is critical. Such care is best delivered in combination with affordable supportive housing.

ABSTRACT Objective Methods Results Discussion To explore dietary‐restraint as a mediator of binge eating and weight‐loss outcomes within a randomized controlled trial comparing cognitive‐behavioral therapy (CBT) and behavioral weight loss (BWL) for binge‐eating disorder (BED) with obesity.Ninety participants were randomly assigned to CBT or BWL and assessed by evaluators blinded to conditions at pretreatment, throughout‐, and post‐treatment (6 months). Three dietary‐restraint measures (Eating Disorder Examination‐Questionnaire [EDE‐Q]‐Restraint, Three‐Factor Flexible‐Restraint and Rigid‐Restraint) were administered at pretreatment and after 2 months of treatment. Regression models examined whether changes at 2‐months in the restraint scales mediated the effects of treatment (CBT versus BWL) on binge eating and weight‐loss outcomes at post‐treatment.CBT and BWL had similar binge‐eating outcomes and similar changes in EDE‐Q‐restraint and flexible‐restraint. BWL had greater 2‐month increases in rigid‐restraint and greater weight‐loss at posttreatment than CBT, with results suggesting 2‐month changes in rigid‐restraint mediated the greater difference (>7 pounds) in weight‐loss. The observed mediation effect of 2.92 suggests 39% of total treatment‐effect on weight‐loss was mediated through 2‐month increases in rigid‐restraint.This secondary analysis within a trial comparing CBT and BWL for BED suggests early‐change in rigid‐restraint has a mediating effect of BWL on weight‐loss. Findings indicate that BWL improves binge eating and challenge views that dietary‐restraint might exacerbate binge eating in BED with obesity. Findings require confirmation using hypothesis‐testing in future trials.Trial Registration: Clinicaltrials.gov: NCT00537758 (“Treatment for Obesity and Binge Eating Disorder”) [ABSTRACT FROM AUTHOR]

Background: Smartbands can be used to detect cigarette smoking and deliver real time smoking interventions. Brief mindfulness interventions have been found to reduce smoking. Objective: This single arm feasibility trial used a smartband to detect smoking and deliver brief mindfulness exercises. Methods: Daily smokers who were motivated to reduce their smoking wore a smartband for 60 days. For 21 days, the smartband monitored, detected and notified the user of smoking in real time. After 21 days, a 'mindful smoking' exercise was triggered by detected smoking. After 28 days, a 'RAIN' (recognize, allow, investigate, nonidentify) exercise was delivered to predicted smoking. Participants received mindfulness exercises by text message and online mindfulness training. Feasibility measures included treatment fidelity, adherence and acceptability. Results: Participants (N=155) were 54% female, 76% white non-Hispanic, and treatment starters (n=115) were analyzed. Treatment fidelity cutoffs were met, including for detecting smoking and delivering mindfulness exercises. Adherence was mixed, including moderate smartband use and low completion of mindfulness exercises. Acceptability was mixed, including high helpfulness ratings and mixed user experiences data. Retention of treatment starters was high (81.9%). Conclusions: Findings demonstrate the feasibility of using a smartband to track smoking and deliver quit smoking interventions contingent on smoking.

Background and Objectives: Childhood trauma (CT) increases addiction vulnerability. We examined CT's impact on delta‐9‐tetrahydrocannabinol (THC) effects. Methods: This is a post‐hoc analysis of a randomized, placebo‐controlled, crossover trial investigating the effects of oral THC (10, 20 mg) among 25 persons receiving methadone for opioid use disorder (OUD). Results: Greater CT was associated with lower aversive effects from higher THC doses (20 mg) (p =.006). Discussion and Conclusions: CT may reduce the subjective aversive effects of THC, potentially leading to greater cannabis use in individuals with OUD. Scientific Significance: These findings offer insights into THC's risks versus benefits in OUD subgroups and emphasize assessing CT in OUD treatment and research. [ABSTRACT FROM AUTHOR]

Gamma (γ)-band oscillations play a key role in perception, associative learning, and conscious awareness and have been shown to be disrupted by cannabinoids in animal studies. The goal of this study was to determine whether cannabinoids disrupt γ-oscillations in humans and whether these effects relate to their psychosis-relevant behavioral effects. The acute, dose-related effects of Δ-9-tetrahydrocannabinol (Δ(9)-THC) on the auditory steady-state response (ASSR) were studied in humans (n=20) who completed 3 test days during which they received intravenous Δ(9)-THC (placebo, 0.015, and 0.03 mg/kg) in a double-blind, randomized, crossover, and counterbalanced design. Electroencephalography (EEG) was recorded while subjects listened to auditory click trains presented at 20, 30, and 40 Hz. Psychosis-relevant effects were measured with the Positive and Negative Syndrome scale (PANSS). Δ(9)-THC (0.03 mg/kg) reduced intertrial coherence (ITC) in the 40 Hz condition compared with 0.015 mg/kg and placebo. No significant effects were detected for 30 and 20 Hz stimulation. Furthermore, there was a negative correlation between 40 Hz ITC and PANSS subscales and total scores under the influence of Δ(9)-THC. Δ(9)-THC (0.03 mg/kg) reduced evoked power during 40 Hz stimulation at a trend level. Recent users of cannabis showed blunted Δ(9)-THC effects on ITC and evoked power. We show for the first time in humans that cannabinoids disrupt γ-band neural oscillations. Furthermore, there is a relationship between disruption of γ-band neural oscillations and psychosis-relevant phenomena induced by cannabinoids. These findings add to a growing literature suggesting some overlap between the acute effects of cannabinoids and the behavioral and psychophysiological alterations observed in psychotic disorders.

Purpose: Aging is a major societal concern due to age-related functional losses. Synapses are crucial components of neural circuits, and synaptic density could be a sensitive biomarker to evaluate brain function. [11C]UCB-J is a positron emission tomography (PET) ligand targeting synaptic vesicle glycoprotein 2A (SV2A), which can be used to evaluate brain synaptic density in vivo. Methods: We evaluated age-related changes in gray matter synaptic density, volume, and blood flow using [11C]UCB-J PET and magnetic resonance imaging (MRI) in a wide age range of 80 cognitive normal subjects (21–83 years old). Partial volume correction was applied to the PET data. Results: Significant age-related decreases were found in 13, two, and nine brain regions for volume, synaptic density, and blood flow, respectively. The prefrontal cortex showed the largest volume decline (4.9% reduction per decade: RPD), while the synaptic density loss was largest in the caudate (3.6% RPD) and medial occipital cortex (3.4% RPD). The reductions in caudate are consistent with previous SV2A PET studies and likely reflect that caudate is the site of nerve terminals for multiple major tracts that undergo substantial age-related neurodegeneration. There was a non-significant negative relationship between volume and synaptic density reductions in 16 gray matter regions. Conclusion: MRI and [11]C-UCB-J PET showed age-related decreases of gray matter volume, synaptic density, and blood flow; however, the regional patterns of the reductions in volume and SV2A binding were different. Those patterns suggest that MR-based measures of GM volume may not be directly representative of synaptic density. [ABSTRACT FROM AUTHOR]
