ABSTRACT

BACKGROUND: People with serious mental illness (SMI) and people with intellectual disabilities/developmental disabilities (ID/DD) are at higher risk for COVID-19 and more severe outcomes. We compare a tailored versus general best practice COVID-19 prevention program in group homes (GHs) for people with SMI or ID/DD in Massachusetts (MA). METHODS: A hybrid effectiveness-implementation cluster randomized control trial compared a four-component implementation strategy (Tailored Best Practices: TBP) to dissemination of standard prevention guidelines (General Best-Practices: GBP) in GHs across six MA behavioral health agencies. GBP consisted of standard best practices for preventing COVID-19. TBP included GBP plus four components including: (1) trusted-messenger peer testimonials on benefits of vaccination; (2) motivational interviewing; (3) interactive education on preventive practices; and (4) fidelity feedback dashboards for GHs. Primary implementation outcomes were full COVID-19 vaccination rates (baseline: 1/1/2021-3/31/2021) and fidelity scores (baseline: 5/1/21-7/30/21), at 3-month intervals to 15-month follow-up until October 2022. The primary effectiveness outcome was COVID-19 infection (baseline: 1/1/2021-3/31/2021), measured every 3 months to 15-month follow-up. Cumulative incidence of vaccinations were estimated using Kaplan-Meier curves. Cox frailty models evaluate differences in vaccination uptake and secondary outcomes. Linear mixed models (LMMs) and Poisson generalized linear mixed models (GLMMs) were used to evaluate differences in fidelity scores and incidence of COVID-19 infections. RESULTS: GHs (n=415) were randomized to TBP (n=208) and GBP (n=207) including 3,836 residents (1,041 ID/DD; 2,795 SMI) and 5,538 staff. No differences were found in fidelity scores or COVID-19 incidence rates between TBP and GBP, however TBP had greater acceptability, appropriateness, and feasibility. No overall differences in vaccination rates were found between TBP and GBP. However, among unvaccinated group home residents with mental disabilities, non-White residents achieved full vaccination status at double the rate for TBP (28.6%) compared to GBP (14.4%) at 15 months. Additionally, the impact of TBP on vaccine uptake was over two-times greater for non-White residents compared to non-Hispanic White residents (ratio of HR for TBP between non-White and non-Hispanic White: 2.28, p = 0.03). CONCLUSION: Tailored COVID-19 prevention strategies are beneficial as a feasible and acceptable implementation strategy with the potential to reduce disparities in vaccine acceptance among the subgroup of non-White individuals with mental disabilities.

ABSTRACT

BACKGROUND AND HYPOTHESIS: Up to 43% of people with schizophrenia have a lifetime cannabis use disorder (CUD). Tetrahydrocannabinol (THC) has been shown to exacerbate psychosis in a dose-dependent manner, but little research has assessed its effects on schizophrenia and co-occurring CUD (SCZ-CUD). In this double-dummy, placebo-controlled trial (total n = 130), we hypothesized that a modest dose of THC would worsen cognitive function but not psychosis. STUDY DESIGN: Effects of single-dose oral THC (15 mg dronabinol) or smoked 3.5% THC cigarettes vs placebo in SCZ-CUD or CUD-only on positive and negative symptoms of schizophrenia (only for SCZ-CUD), cognition, and drug experiences assessed several hours after drug administration. SCZ-only and healthy control participants were also assessed. STUDY RESULTS: Drug liking was higher in THC groups vs placebo. Neither smoked THC nor oral dronabinol predicted positive or negative symptom subscale scores 2 and 5 h, respectively, after drug exposure in SCZ-CUD participants. The oral dronabinol SCZ-CUD group, but not smoked THC SCZ-CUD group, performed worse than placebo on verbal learning (B = -9.89; 95% CI: -16.06, -3.18; P = .004) and attention (B = -0.61; 95% CI: -1.00, -0.23; P = .002). Every 10-point increment in serum THC + THCC ng/ml was associated with increased negative symptoms (0.40 points; 95% CI: 0.15, 0.65; P = .001; subscale ranges 7-49) and trends were observed for worse positive symptoms and performance in verbal learning, delayed recall, and working memory. CONCLUSIONS: In people with SCZ-CUD, a modest single dose of oral THC was associated with worse cognitive functioning without symptom exacerbation several hours after administration, and a THC dose-response effect was seen for negative symptoms.

ABSTRACT

Cerebral ischemia/reperfusion (I/R) injury increases blood-brain barrier (BBB) permeability, leading to hemorrhagic transformation and brain edema. Normobaric oxygen (NBO) is a routine clinical treatment strategy for this condition. However, its neuroprotective effects remain controversial. This study investigated the effect of different NBO concentrations on I/R injury and explores the involvement of the nuclear factor erythroid 2-related factor 2 (Nrf2) pathway in the underlying mechanism. A mouse middle cerebral artery occlusion (MCAO) model, and an oxygen and glucose deprivation (OGD) model featuring mouse brain microvascular endothelial cells (ECs) called bEnd.3, were used to investigate the effect of NBO on I/R injury. A reactive oxygen species (ROS) inducer and Nrf2-knockdown by RNA were used to explore whether the Nrf2 pathway mediates the effect of NBO on cerebrovascular ECs. In the early stage of MCAO, 40% O2 NBO exposure significantly improved blood perfusion in the ischemic area and effectively relieved BBB permeability, cerebral edema, cerebral injury, and neurological function after MCAO. In the OGD model, 40% O2 NBO exposure significantly reduced apoptosis, inhibited ROS generation, reduced ER stress, upregulated the expression of tight junction proteins, and stabilized the permeability of ECs. Blocking the Nrf2 pathway nullified the protective effect of 40% O2 NBO on ECs after OGD. Finally, our study confirmed that low concentrations of NBO have a neuroprotective effect on I/R by activating the Nrf2 pathway in ECs.

ABSTRACT

Aqueous electrolytes possess non-combustible and eco-friendly features compared to organic electrolytes, leading them to be more suitable for application in smart windows for daily use. However, limited by the narrow electrochemical window of water (1.23 V), its use in conventional electrochromic devices (ECDs) would result in irreversible performance loss, which arises from decomposition caused by high voltage. Here, we propose a synergistic scheme combining a redox couple-catalytic counter electrode (RC-CCE) strategy with protons as guest ions. With the help of the intelligent matching of the reaction potentials of the RC and amorphous WO3 electrochromic electrodes and the highly active and fast kinetic features of protons, it successfully reduces the working voltage range of the device to 1.1 V. The assembled HClO4-ECD can possess an overall modulation rate (350-1200 nm) of 0.43 and 0.94 at -0.1 and -0.7 V, respectively, and a modulation of 66.8% at 600 nm at -0.7 V. Moreover, compared with other guest ions, the proton-based ECD exhibits higher coloration efficiency, a broader color modulation capability, and better stability. In addition, the house model equipped with the proton-based ECD effectively blocks solar radiation, which provides a potential solution for the design of aqueous smart windows.

ABSTRACT

Complementary electrochromic devices (ECDs) composed of WO3 and NiO electrodes have wide applications in smart windows. However, they have poor cycling stability due to ion-trapping and charge mismatch between electrodes, which limits their practical application. In this work, we introduce a partially covered counter electrode (CE) composed of NiO and Pt to achieve good stability and overcome the charge mismatch based on our structure of electrochromic electrode/Redox/catalytic counter electrode (ECM/Redox/CCE). The device is assembled using a NiO-Pt counter electrode with WO3 as the working electrode, and PC/LiClO4 containing a tetramethylthiourea/tetramethylformaminium disulfide (TMTU/TMFDS2+) redox couple as the electrolyte. The partially covered NiO-Pt CE-based ECD exhibits excellent EC performance, including a large optical modulation of 68.2% at 603 nm, rapid switching times of 5.3 s (coloring) and 12.8 s (bleaching), and a high coloration efficiency of 89.6 cm2·C-1. In addition, the ECD achieves a good stability of 10,000 cycles, which is promising for practical application. These findings suggest that the structure of ECC/Redox/CCE could overcome the charge mismatch problem. Moreover, Pt could enhance the Redox couple's electrochemical activity for achieving high stability. This research provides a promising approach for the design of long-term stable complementary electrochromic devices.

ABSTRACT

INTRODUCTION: People with schizophrenia and other serious mental illnesses (SMI) represent a concerning health disparity population, with 10-30 fewer years of life compared to the general population, mainly from high rates of cardiovascular disease (CVD). Preventing CVD is possible with exercise and diet interventions, but only 50 % of participants in clinical trials achieve reduction in CVD risk. This study assessed whether cash incentives improved weight loss, cardiovascular endurance, and/or mortality risk when added to one of four healthy lifestyle programs (gym membership, Weight Watchers membership, the InSHAPE program, InSHAPE + Weight Watchers). METHODS: From 2012 to 2015, 1348 overweight or obese adults with SMI enrolled in a study using equipoise stratified randomization. Participants were randomly assigned to intervention, then to cash incentives, or not, for participation (gym and/or Weight Watchers), with baseline and quarterly assessments for 12 months. We examined effects of the interventions, key covariates, and incentives, using generalized linear models. RESULTS: Main effects of randomization to receive cash incentives was not significant for any outcome; whereas total amount of incentives was significantly associated with all three primary outcomes (weight loss, cardiovascular endurance, mortality risk), mainly for participants in the InSHAPE+WW group who received additional cash incentives. CONCLUSIONS: Incentives may be effective at preventing CVD and improving health outcomes for people with SMI, especially in the context of intensive support for healthy lifestyle behaviors. Policy changes are required to increase access to healthy lifestyle programming and more research is needed to establish the optimal amount of incentives for people with SMI.

ABSTRACT

AIM: The purpose of this study was to examine factors associated with weight gain prevention among young adults with serious mental illness who participated in the Fit Forward randomized controlled trial evaluating lifestyle interventions adapted for this high-risk group. The aims were to: (1) examine baseline differences between participants that gained weight and those that lost or maintained weight at six and 12 months, and (2) evaluate whether changes in weight control strategies were associated with weight gain prevention at 6 and 12 months. METHODS: This study was a secondary analysis of the Fit Forward Study. Participants were young adults (age 18-35) with a serious mental illness and a body mass index in the overweight or obese range. Participants completed assessments at baseline and 6 and 12 months. t-Tests and chi-squared tests were used to examine baseline differences between those that gained weight and those that lost/maintained weight. Logistic regression was used to evaluate whether changes in weight control strategies were associated with weight gain prevention in the sample overall. RESULTS: Lower baseline BMI was significantly associated with weight gain prevention at six and 12 months. Greater increases in weight control strategies total score and psychological coping subscale were significantly associated with weight gain prevention at six and 12 months. CONCLUSIONS: Weight control strategies, particularly psychological coping tools that support positive thinking and reduce negative self-talk should be considered as core strategies in healthy lifestyle interventions aimed at preventing weight gain in young adults with serious mental illness.

ABSTRACT

BACKGROUND: People with serious mental illness (SMI) and intellectual disabilities and/or developmental disabilities (ID/DD) living in group homes (GHs) and residential staff are at higher risk for COVID-19 infection, hospitalization, and death compared with the general population. METHODS: We describe a hybrid type 1 effectiveness-implementation cluster randomized trial to assess evidence-based infection prevention practices to prevent COVID-19 for residents with SMI or ID/DD and the staff in GHs. The trial will use a cluster randomized design in 400 state-funded GHs in Massachusetts for adults with SMI or ID/DD to compare effectiveness and implementation of "Tailored Best Practices" (TBP) consisting of evidence-based COVID-19 infection prevention practices adapted for residents with SMI and ID/DD and GH staff; to "General Best Practices" (GBP), consisting of required standard of care reflecting state and federal standard general guidelines for COVID-19 prevention in GHs. External (i.e., community-based research staff) and internal (i.e., GH staff leadership) personnel will facilitate implementation of TBP. The primary effectiveness outcome is incident SARS-CoV-2 infection and secondary effectiveness outcomes include COVID-19-related hospitalizations and mortality in GHs. The primary implementation outcomes are fidelity to TBP and rates of COVID-19 vaccination. Secondary implementation outcomes are adoption, adaptation, reach, and maintenance. Outcomes will be assessed at baseline, 3-, 6-, 9-, 12-, and 15-months post-randomization. CONCLUSIONS: This study will advance knowledge on comparative effectiveness and implementation of two different strategies to prevent COVID-19-related infection, morbidity, and mortality and promote fidelity and adoption of these interventions in high-risk GHs for residents with SMI or ID/DD and staff.

ABSTRACT

The regioselective hydroamination of unactivated alkenes is a long-standing challenge in organic synthesis. Herein, we report a NiH-catalyzed proximal-selective hydroamination of unactivated alkenes with 8-aminoquinoline (AQ) as a bidentate auxiliary and anthranils as aminating reagents. A wide range of primary aryl amines bearing an ortho-carbonyl group were installed in both terminal and internal unactivated alkenes, delivering a variety of valuable ß- and γ-amino acid building blocks, respectively, with excellent regiocontrol. The utility of this transformation was further demonstrated by the conversion of the multifunctionalized aryl amines into useful N-heterocycles.

ABSTRACT

BACKGROUND: Schizophrenia and related disorders are highly disabling and create substantial burdens for families, communities, and health care systems. Although pharmacological treatments can often lessen the psychotic symptoms that are a hallmark of schizophrenia, they do not lessen the social and cognitive deficits that create the greatest impediments to community engagement and functional recovery. This study builds on prior research on psychosocial rehabilitation by comparing the effectiveness of two treatments demonstrated as efficacious in improving social and community functioning, Cognitive Enhancement Therapy (CET) and a version of Social Skills Training (HOPES/SST). METHODS: The study uses a randomized cluster design in which a pair of clinicians at community- and hospital-based mental service centers deliver either CET or HOPES to at least one group of 6-8 eligible clients for 12 months. Clinicians are trained and then supervised weekly, with ongoing process measurement of treatment fidelity, attendance, satisfaction, and retention, and use of other services. Measures administered at baseline and at 6 and 12 months while in treatment, and then at 18 and 24 months after treatment include social adjustment, quality of life, social skills, positive and negative symptoms, and neuro- and social cognition. We hypothesize that CET will be associated with greater improvements than SST in both the primary outcome of community functioning and the secondary outcomes of neuro- and social cognition and social skills. Secondarily, we hypothesize that more cognitive impairment at baseline and younger age will predict more benefit from CET compared to HOPES. DISCUSSION: Resource shortages endemic in mental health services and exacerbated by the pandemic highlight the importance of identifying the most effective approach to improving social and community functioning. We aim to improve understanding of the impact of two efficacious psychosocial treatments and to improve clinicians' ability to refer to both treatments the individuals who are most likely to benefit from them. We expect the result to be programmatic improvements that improve the magnitude and durability of gains in community functioning.

ABSTRACT

BACKGROUND: Social media sites, dating apps, and information search sites have been used to reach individuals at high risk for HIV infection. However, it is not clear which platform is the most efficient in promoting home HIV self-testing, given that the users of various platforms may have different characteristics that impact their readiness for HIV testing. OBJECTIVE: This study aimed to compare the relative effectiveness of social media sites, dating apps, and information search sites in promoting HIV self-testing among minority men who have sex with men (MSM) at an increased risk of HIV infection. Test kit order rates were used as a proxy to evaluate promotion effectiveness. In addition, we assessed differences in characteristics between participants who ordered and did not order an HIV test kit. METHODS: Culturally appropriate advertisements were placed on popular sites of three different platforms: social media sites (Facebook, Instagram), dating apps (Grindr, Jack'D), and information search sites (Google, Bing). Advertisements targeted young (18-30 years old) and minority (Black or Latinx) MSM at risk of HIV exposure. Recruitment occurred in 2 waves, with each wave running advertisements on 1 platform of each type over the same period. Participants completed a baseline survey assessing sexual or injection use behavior, substance use including alcohol, psychological readiness to test, attitudes toward HIV testing and treatment, and HIV-related stigma. Participants received an electronic code to order a free home-based HIV self-test kit. Follow-up assessments were conducted to assess HIV self-test kit use and uptake of pre-exposure prophylaxis (PrEP) at 14 and 60 days post enrollment. RESULTS: In total, 271 participants were enrolled, and 254 were included in the final analysis. Among these 254 participants, 177 (69.7%) ordered a home HIV self-test kit. Most of the self-test kits were ordered by participants enrolled from dating apps. Due to waves with low enrollment, between wave statistical comparisons were not feasible. Within wave comparison revealed that Jack'D showed higher order rates (3.29 kits/day) compared to Instagram (0.34 kits/day) and Bing (0 kits/day). There were no associations among self-test kit ordering and HIV-related stigma, perceptions about HIV testing and treatment, and mistrust of medical organizations. CONCLUSIONS: Our findings show that using popular dating apps might be an efficient way to promote HIV self-testing. Stigma, perceptions about HIV testing and treatment, or mistrust of medical organizations may not affect order rates of HIV test kits promoted on the internet.

ABSTRACT

BACKGROUND: Despite widespread use of learning collaboratives, few randomized trials have evaluated their effectiveness as a strategy for implementing evidence based practices. This randomized trial evaluated the effectiveness of a virtual learning collaborative (VLC) in the implementation of a health promotion program for persons with serious mental illness (SMI) aimed at reducing cardiovascular risk reduction in routine mental health settings, compared to routine technical assistance (TA). METHODS: Fifty-five mental health provider organizations were recruited to participate in a Hybrid Type 3 cluster randomized implementation-effectiveness trial of the InSHAPE health promotion program for persons with SMI. Sites were stratified by size and randomized prior to implementation to an 18-month group-based VLC with monthly learning sessions or individual site TA with four scheduled conference calls over 18 months. Primary implementation and service outcomes were InSHAPE program fidelity, participation, and reach. Primary clinical outcomes were weight loss, cardiorespiratory fitness, and cardiovascular risk reduction (≥ 5% weight loss or > 50 m increase on the 6-Minute Walk Test). Program fidelity was assessed at 6, 12, and 24 months; program participation and participant-level outcomes were assessed at 3, 6, 9, and 12 months. RESULTS: VLC (N = 27) and TA (N = 28) sites were similar in organizational characteristics (all p > 0.05). At 12-month follow-up mean program fidelity score was higher in VLC compared to TA (90.5 vs. 79.1; p = 0.002), with over double the proportion with good fidelity (VLC = 73.9% vs. TA = 34.8%; p = 0.009). Over half of individuals in both VLC and TA achieved cardiovascular risk-reduction at 6-month follow-up (VLC: 51.0%; TA: 53.5%; p = 0.517) and at 12-month follow-up (62% VLC and TA; p = 0.912). At 12-month follow-up VLC compared to TA was associated with greater participation (VLC 69.5% vs. TA 56.4% attending at least 50% of sessions, p = 0.002); larger caseloads (VLC = 16 vs. TA = 11; p = 0.024); greater reach consisting of 45% greater number of participants receiving InSHAPE (VLC = 368 vs. TA = 253), and 58% greater number of participants achieving cardiovascular risk reduction (VLC = 150 vs. TA = 95). CONCLUSION: Virtual learning collaboratives compared to routine technical assistance as an implementation strategy for evidence-based health promotion promote greater intervention fidelity, greater levels of intervention participation, greater reach, and a greater number of participants achieving clinically significant risk reduction outcomes, while achieving similarly high levels of intervention effectiveness for participants who completed at least 6 months of the program.

ABSTRACT

BACKGROUND: Self-regulation refers to a person's ability to manage their cognitive, emotional, and behavioral processes to achieve long-term goals. Most prior research has examined self-regulation at the individual level; however, individual-level assessments do not allow the examination of dynamic patterns of intraindividual variability in self-regulation and thus cannot aid in understanding potential malleable processes of self-regulation that may occur in response to the daily environment. OBJECTIVE: This study aims to develop a brief, psychometrically sound momentary self-regulation scale that can be practically administered through participants' mobile devices at a momentary level. METHODS: This study was conducted in 2 phases. In the first phase, in a sample of 522 adults collected as part of a larger self-regulation project, we examined 23 previously validated assessments of self-regulation containing 594 items in total to evaluate the underlying structure of self-regulation via exploratory and confirmatory factor analyses. We then selected 20 trait-level items to be carried forward to the second phase. In the second phase, we converted each item into a momentary question and piloted the momentary items in a sample of 53 adults over 14 days. Using the results from the momentary pilot study, we explored the psychometric properties of the items and assessed their underlying structure. We then proposed a set of subscale and total score calculations. RESULTS: In the first phase, the selected individual-level items appeared to measure 4 factors of self-regulation. The factors identified were perseverance, sensation seeking, emotion regulation, and mindfulness. In the second phase of the ecological momentary assessment pilot, the selected items demonstrated strong construct validity as well as predictive validity for health risk behaviors. CONCLUSIONS: Our findings provide preliminary evidence for a 12-item momentary self-regulation scale comprising 4 subscales designed to capture self-regulatory dynamics at the momentary level.

ABSTRACT

Introduction: Self-regulation has been implicated in health risk behaviors and is a target of many health behavior interventions. Despite most prior research focusing on self-regulation as an individual-level trait, we hypothesize that self-regulation is a time-varying mechanism of health and risk behavior that may be influenced by momentary contexts to a substantial degree. Because most health behaviors (e.g., eating, drinking, smoking) occur in the context of everyday activities, digital technologies may help us better understand and influence these behaviors in real time. Using a momentary self-regulation measure, the current study (which was part of a larger multi-year research project on the science of behavior change) used ecological momentary assessment (EMA) to assess if self-regulation can be engaged and manipulated on a momentary basis in naturalistic, non-laboratory settings. Methods: This one-arm, open-label exploratory study prospectively collected momentary data for 14 days from 104 participants who smoked regularly and 81 participants who were overweight and had binge-eating disorder. Four times per day, participants were queried about momentary self-regulation, emotional state, and social and environmental context; recent smoking and exposure to smoking cues (smoking sample only); and recent eating, binge eating, and exposure to binge-eating cues (binge-eating sample only). This study used a novel, momentary self-regulation measure comprised of four subscales: momentary perseverance, momentary sensation seeking, momentary self-judgment, and momentary mindfulness. Participants were also instructed to engage with Laddr, a mobile application that provides evidence-based health behavior change tools via an integrated platform. The association between momentary context and momentary self-regulation was explored via mixed-effects models. Exploratory assessments of whether recent Laddr use (defined as use within 12 h of momentary responses) modified the association between momentary context and momentary self-regulation were performed via mixed-effects models. Results: Participants (mean age 35.2; 78% female) in the smoking and binge-eating samples contributed a total of 3,233 and 3,481 momentary questionnaires, respectively. Momentary self-regulation subscales were associated with several momentary contexts, in the combined as well as smoking and binge-eating samples. For example, in the combined sample momentary perseverance was associated with location, positively associated with positive affect, and negatively associated with negative affect, stress, and tiredness. In the smoking sample, momentary perseverance was positively associated with momentary difficulty in accessing cigarettes, caffeine intake, and momentary restraint in smoking, and negatively associated with temptation and urge to smoke. In the binge-eating sample, momentary perseverance was positively associated with difficulty in accessing food and restraint in eating, and negatively associated with urge to binge eat. While recent Laddr use was not associated directly with momentary self-regulation subscales, it did modify several of the contextual associations, including challenging contexts. Conclusions: Overall, this study provides preliminary evidence that momentary self-regulation may vary in response to differing momentary contexts in samples from two exemplar populations with risk behaviors. In addition, the Laddr application may modify some of these relationships. These findings demonstrate the possibility of measuring momentary self-regulation in a trans-diagnostic way and assessing the effects of momentary, mobile interventions in context. Health behavior change interventions may consider measuring and targeting momentary self-regulation in addition to trait-level self-regulation to better understand and improve health risk behaviors. This work will be used to inform a later stage of research focused on assessing the transdiagnostic mediating effect of momentary self-regulation on medical regimen adherence and health outcomes.

ABSTRACT

BACKGROUND: High cigarette smoking prevalence and low quit rates in people with serious mental illness (SMI) contribute to disparate rates of chronic disease and premature death. This prospective trial tested the impact of switching to a potentially lower-harm nicotine-containing product on smoking in this population. AIMS AND METHODS: A total of 240 cigarette smokers with SMI who tried but were currently unwilling to quit were randomly assigned to receive disposable e-cigarettes for 8 weeks or not, with assessments at baseline, 2, 4, 6, 8, 13, and 26 weeks. Generalized linear mixed models examined the effects of e-cigarette provision on e-cigarette appeal, cigarettes per day (CPD), breath carbon monoxide (CO), nicotine dependence, and side effects. Clinical Trial registration: NCT03050853. RESULTS: Self-reported smoking was similar between groups at baseline (mean = 18.7 CPD). By week 2, 79% of the e-cigarette group were using e-cigarettes daily. During weeks 2-8, CPD and CO decreased in the e-cigarette versus assessment-only group (eg, 7.5 CPD [95% CI = 5.9, 9.2] vs. 18.1 CPD [CI = 16.4, 19.8] and 16.4 ppm [CI = 13.4, 19.5] vs. 25.4 ppm [CI = 22.4, 28.9], respectively, at week 2). Additionally, 19%-22% in the e-cigarette group reported smoking no cigarettes in weeks 2-8 compared to 0% in the assessment-only group. By 13 and 26 weeks, group differences in CPD, but not CO, remained significant. Nicotine dependence did not increase and side effects were minor. CONCLUSIONS: Providing e-cigarettes for 8 weeks to smokers with SMI resulted in substantial reductions in CPD and CO. Enhancing and maintaining switching from cigarettes to e-cigarettes warrant further study. IMPLICATIONS: This was the first prospective study to compare e-cigarette provision with assessments only to evaluate the appeal and impact of e-cigarettes on smoking behavior, carbon monoxide exposure, and nicotine dependence among smokers with SMI who had tried but were unable to quit and were not currently interested in cessation treatment. The finding that e-cigarette provision led to significant reductions in smoking and carbon monoxide without increasing nicotine dependence has implications for reducing harm not only among the millions of smokers with SMI who struggle to quit, but also for other vulnerable smokers who cannot achieve cessation.

ABSTRACT

Flexible piezoresistive pressure sensors have been attracted a lot of attention due to their simple mechanism, easy fabrication, and convenient signal acquisition and analysis. Herein, a new flexible piezoresistive sensor based on microstructured electrospun rough polyurethane (PU) nanofibers film is assembled. The microstructured PU film with tiny bumps is prepared in one step via electrospinning technology, which imparts a microstructured rough upper surface and a smooth lower surface. With this unique microstructure, we have made it possible for PU/Ag films to serve as sensing layers for piezoresistive sensors by introducing a silver conductive layer on the surface of electrospun PU film. The fabricated piezoresistive pressure sensor delivers high sensitivity (10.53 kPa-1 in the range of 0-5 kPa and 0.97 kPa-1 in the range of 6-15 kPa), fast response time (60 ms), fast recovery time (30 ms), and long-time stability (over 10,000 cycles). This study presents a fabrication strategy to prepare the microstructured PU nanofiber film using electrospinning technology directly, and the as-developed sensor shows promise in applications such as wrist pulse measurement, finger movement monitoring, etc., proving its great potential for monitoring human activities.

ABSTRACT

OBJECTIVE: Cognitive functioning is a potent predictor of work in people with a severe mental illness, including those receiving vocational services. Cognitive remediation has been shown to improve cognitive functioning and work outcomes in people receiving vocational services. However, it is unknown whether it reduces the strength of cognitive functioning as a predictor of work outcomes compared to people receiving vocational services alone. METHOD: Data were pooled from five randomized controlled trials evaluating the effects of adding cognitive remediation to vocational rehabilitation vs. vocational services alone. A battery of baseline cognitive functioning measures was examined to identify predictors of competitive work outcomes over the following two years. Study condition (i.e., receipt of cognitive remediation) was included in the analyses to evaluate whether cognitive functioning was a weaker predictor of work outcomes in people receiving cognitive remediation compared to those receiving vocational services alone. RESULTS: Cognitive functioning was a stronger predictor of wages earned and weeks worked in participants receiving vocational services alone than those who also received cognitive remediation. Cognitive functioning did not predict job acquisition in either study condition. CONCLUSION: Cognitive remediation may improve employment outcomes in people receiving vocational services in part by reducing the adverse effects of impaired cognitive functioning on work performance.

ABSTRACT

AIM: To characterize subjective sleep quality and examine its associations with mental health, physical health and health behaviours in a transdiagnostic sample of young adults with serious mental illness (SMI) enrolled in a lifestyle intervention trial. METHODS: Baseline data from a lifestyle intervention trial with young adults (ages 18-35 years) with SMI included the Pittsburgh Sleep Quality Index (PSQI), mental health, physical health and health behaviour outcomes. Descriptive statistics and multiple linear regression were used in analyses. RESULTS: Of 150 participants, 76% were categorized with poor sleep quality. Depressive symptoms were significantly associated with sleep quality (ß = .438, p < .001); however, no association was found with physical health and health behaviours. CONCLUSIONS: Young adults with SMI enrolled in lifestyle interventions may benefit from treatment that addresses sleep as part of a comprehensive approach to health promotion with attention to the role of depressive symptoms in sleep quality.

ABSTRACT

BACKGROUND: Pregnant women with opioid use disorder and their infants often experience worse perinatal outcomes than women without opioid use disorder, including longer hospitalizations after delivery and a higher risk for preterm delivery. Integrated treatment models, which combine addiction treatment and maternity care, represent an innovative approach that is widely endorsed, however, limited studies have compared the outcomes between integrated and standard, nonintegrated programs from real-world programs. OBJECTIVE: This study aimed to evaluate the perinatal and substance use outcomes for pregnant women with opioid use disorder receiving coordinated, colocated obstetrical care and opioid use disorder treatment (integrated treatment) and to compare it with those of women receiving obstetrical care and opioid use disorder treatment in distinct programs of care (nonintegrated treatment). STUDY DESIGN: In this observational, retrospective cohort study, we abstracted the perinatal and opioid use disorder treatment data from the records of pregnant women with opioid use disorder (n=225) who delivered at a rural, academic medical center from 2015 to 2017. The women either received integrated (n=92) or nonintegrated (n=133) opioid use disorder treatment and obstetrical care. Using inverse probability weighted regression models to adjust for a potential covariate imbalance, we evaluated the impact of the treatment model on the risk for preterm delivery and positive meconium or umbilical cord toxicology screens. We explored whether the number of obstetrical visits mediated this relationship by using a quasi-Bayesian Monte Carlo algorithm. RESULTS: Women receiving integrated treatment were less likely to deliver prematurely (11.8% vs 26.6%; P<.001) and their infants had shorter hospitalizations (6.5±4.8 vs 10.7±16.2 days). Using a robust inverse probability weighted model showed that receiving integrated treatment was associated with a 74.7% decrease in the predicted probability of preterm delivery (average treatment effect, -0.19; standard error, 0.14; P<.001). There were no differences in the risk for a positive meconium or umbilical cord toxicology screen, a marker for second and third trimester substance use, between women receiving integrated treatment and those receiving coordinated treatment (29.4% vs 34.6%; P=.41), however, integrated treatment was associated with significantly lower rates of positive maternal urine toxicology screens at the time of delivery (35.9% vs 74.4%; P<.001). CONCLUSION: Among a cohort of rural pregnant women with opioid use disorder, receiving integrated obstetrical care and opioid use disorder treatment was associated with a reduced risk for preterm birth, a lower risk for positive maternal urine toxicology screen at the time of delivery, and shorter infant hospitalization. This relationship was mediated by the number of obstetrical visits attended during pregnancy, suggesting that increased engagement with obstetrical care through integration of services may contribute to improved perinatal outcomes.
