Abstract Background Leading causes of unintentional child injury such as poisoning and falls are preventable, and the majority occur in the home. Numerous home safety interventions have been developed and tested to increase safety behaviors; however, no smart phone-based applications (apps) have been developed and evaluated for this purpose. The objective of this study was to evaluate whether a mobile technology-based health behavior change intervention, the Make Safe Happen® app, was an effective tool to increase safety knowledge and safety actions/behaviors for the prevention of child unintentional injuries in and around the home. Methods Data were collected in pretest and posttest online surveys from an existing nationwide population-based survey panel. Intervention subjects were randomized to organically (participant-driven) use the Make Safe Happen® app for 1 week, which provided home safety information and the ability to purchase safety products, while control participants were assigned to download and use an app about a topic other than home safety. The primary outcomes of safety knowledge and home safety actions were assessed by using linear mixed model regressions with intention-to-treat analyses. Results A total of 5032 participants were randomized to either the intervention (n = 4182) or control (n = 850) group, with 2055 intervention participants downloading and entering their participant IDs into the Make Safe Happen® app. The online posttest survey was completed by 770 intervention and 283 control subjects. Mean knowledge parent safety score increased at a greater rate for intervention than control subjects (p < 0.0001), and at posttest was significantly higher for intervention than control subjects (p < 0.0001). The percentage of intervention subjects who reported doing all one-time and repeated safety actions significantly increased from pretest to posttest (p < 0.0001 and p = 0.0001, respectively), but there was no change among the control subjects (p = 0.1041 and p = 0.9755, respectively). At posttest, this percentage was larger for intervention than control subjects only for repeated safety actions (p = 0.0340). Conclusions The mobile application significantly improved safety knowledge and safety actions for participants using the Make Safe Happen® app, although loss to follow-up was a limitation. The results of this study indicate the usefulness of widespread distribution and use of the Make Safe Happen® app. Trial registration numberNCT02751203; Registered April 26, 2016.

<b><i>Introduction:</i></b> A randomized, controlled trial of a pedometer-based walking intervention with weekly activity goals led to increased walking among dialysis patients. We examined whether impairment per cognitive function screening is associated with adherence and performance in the intervention. <b><i>Methods:</i></b> Thirty dialysis patients were randomly assigned to a 3-month pedometer-based intervention with weekly goals. Participants were administered the Telephone Interview of Cognitive Status (TICS), a test of global mental status. We examined the association of levels of impairment on the TICS (≥33: unimpaired, 26–32: ambiguous impairment, 21–25: mild cognitive impairment [MCI]) with adherence, achieving weekly goals, and increasing steps, physical performance (Short Physical Performance Battery, SPPB), and self-reported physical function (PF) through multivariable linear mixed-model and logistic regression analyses adjusted for age, sex, BMI, dialysis modality, baseline steps, baseline SPPB, and stroke status. <b><i>Results:</i></b> One-third of participants were unimpaired, and 13% had MCI. Participants with worse results on cognitive function screening missed more calls and completed fewer weekly goals than participants with better results. During the intervention, a worse result on cognitive function screening was associated with smaller increases in steps compared to those without impairment: (ambiguous: −620 [95% CI −174, −1,415], MCI: −1,653 [95% CI −120, −3,187]); less improvement in SPPB (ambiguous: −0.22 points [95% CI −0.08, −0.44], MCI: −0.45 [95% CI −0.13, −0.77]); and less improvement in PF (ambiguous: −4.0 points [95% CI −12.2, 4.1], MCI: −14.0 [95% CI −24.9, −3.1]). During the postintervention period, a worse result on cognitive function screening was associated with smaller increases in SPPB (ambiguous: −0.54 [95% CI −1.27, 0.19], MCI: −0.97 [95% CI −0.37, −1.58]) and PF (ambiguous: −3.3 [95% CI −6.5, −0.04], MCI: −10.5 [95% CI −18.7, −2.3]). <b><i>Discussion/Conclusion:</i></b> Participants with worse results on cognitive function screening had worse adherence and derived less benefit from this pedometer-based intervention. Future exercise interventions should be developed incorporating methods to address cognitive impairment, for example, by including caregivers when planning such interventions.

We tested the efficacy of an integrative psychotherapeutic group treatment (IPGT) in reducing vertigo/dizziness-related impairment along with depression, anxiety, and somatization by conducting a randomized controlled superiority trial comparing IPGT to self-help groups moderated by a clinical psychologist (SHG). Adult patients with functional vertigo and dizziness symptoms were randomly allocated to either the IPGT or SHG as active control group. Outcomes were assessed at baseline (t0), after treatment lasting 16 weeks (t1), and 12 months after treatment (t2). A total of 81 patients were assigned to IPGT and 78 patients were assigned to SHG. Vertigo-related impairment was reduced in both conditions (IPGT: t0–t1: d = 1.10, t0–t2: d = 1.06; SHG: t0–t1: d = 0.86, t0–t2: d = 1.29), showing the efficiency of both IPGT and SHG. Clinically relevant improvements were also obtained for depression in both groups. Linear mixed model analyses revealed no differences between groups for all outcomes (effect of group for the primary outcome: b = −1.15, SE = 2.13, t = −0.54, p = 0.59). Attrition rates were higher in SHG (52.6%) than in IPGT (28.4%). Both conditions improved primary and secondary outcomes while IPGT was better accepted by patients than SHG.

Abstract Objective Unintentional injuries are the leading cause of death for children under 19 years of age. For preschoolers, many injuries occur in the home. Addressing this issue, this study assessed if a storybook about home safety could be effective to increase preschoolers’ safety knowledge and reduce their injury-risk behaviors. Methods Applying a randomized controlled trial design, normally developing English speaking preschool children (3.5–5.5 years) in Southwestern Ontario Canada were randomly assigned to the control condition (a storybook about healthy eating, N = 30) or the intervention condition (a storybook about home hazards, N = 29). They read the assigned storybook with their mother for 4 weeks; time spent reading was tracked, and fidelity checks based on home visits were implemented. Results Comparing postintervention knowledge, understanding score, and risk behaviors across groups revealed that children who received the intervention were able to identify more hazards, provide more comprehensive safety explanations, and demonstrate fewer risky behaviors compared with children in the control group (ηp2 = 0.13, 0.19, and 0.51, respectively), who showed no significant changes over time in safety knowledge, understanding, or risk behaviors. Compliance with reading the safety book and fidelity in how they did so were very good. Conclusions A storybook can be an effective resource for educating young children about home safety and reducing their hazard-directed risk behaviors.

The Impact

Objective.To determine the accuracy of self-reported body weight prior to and following a weight loss intervention including daily self-weighing among obese employees.Methods.As part of a 6-month randomized controlled trial including a no-treatment control group, an intervention group received a series of coaching calls, daily self-weighing, and interactive telemonitoring. The primary outcome variable was the absolute discrepancy between self-reported and measured body weight at baseline and at 6 months. We used general linear mixed model regression to estimate changes and differences between study groups over time.Results.At baseline, study participants underreported their weight by an average of 2.06 (se=0.33) lbs. The intervention group self-reported a smaller absolute body weight discrepancy at followup than the control group.Conclusions.The discrepancy between self-reported and measured body weight appears to be relatively small, may be improved through daily self-monitoring using immediate-feedback telehealth technology, and negligibly impacts change in body weight.

IntroductionOccupational therapy (OT) is defined as the promotion of client health and well-being through a client-centred practice. However, there is a tendency to rely on the therapist’s experiences and values, and there is a difference between the client’s and therapist’s perceptions regarding the current activity that the client is engaged in. In previous studies that have applied ‘flow’, activities supported by OT in elderly people were analysed, indicating a difference in recognition. Therefore, we thought that more effective OT could be implemented by adjusting the challenge–skill (ACS) balance, and we invented a novel process termed as ACS balance for OT. The purpose of this study is to verify the effect of ACS-OT on clients in the recovery rehabilitation unit and to prepare a protocol for randomised controlled trial (RCT) implementation.Method and analysisThis single-blind RCT will recruit 80 clients aged 50–99 years admitted to the recovery rehabilitation unit who meet eligibility criteria. Clients will be randomly allocated to receive ACS-OT or standard OT. Both interventions will be performed during the clients’ residence at the unit. The primary outcome measure will be subjective quality of life and will be measured at entry into (pre) and at discharge from (post) the unit and at 3 months afterwards (follow-up). Outcomes will be analysed using a linear mixed model fitted with a maximum likelihood estimation.Ethics and disseminationThis protocol has been approved by the ethics review committee of the Tokyo Metropolitan University (No.17020). Results of this trial will be submitted for publication in a peer-reviewed journal.Trial registration numberUMIN-CTR number, UMIN000029505; Pre-results.

Abstract Introduction This 8-week multisite, randomized controlled trial of snus examined the differential effects of instructions on (1) snus use, (2) smoking and smoking-related measures, and (3) exposure to tobacco-related constituents. Method US adult daily cigarette smokers (n = 150; 43.3% female; Medianage = 43.5) were recruited from Minneapolis, Minnesota; Columbus and Coshocton, Ohio; and Buffalo, New York. Following a 1-week sampling phase of snus, participants who used at least 7 pouches were randomized to either (1) partial substitution (PS; “use snus as you like with your cigarettes”), (2) complete substitution (CS; “avoid cigarettes”), or (3) usual brand cigarettes (UB). Analyses included between-group analyses (eg, PS vs. CS) using Wilcoxon rank sum test of cigarettes per day and snus pouches per day, and a linear mixed model (biomarkers). Results Compared to the PS and UB groups, smokers assigned to CS reported greater reductions in cigarettes per day (ps &lt; .001), using more snus pouches per day (p = .02), and more smoke-free days (CS median = 14.5, PS and UB medians = 0, p &lt; .001). In addition, results demonstrated reductions in carbon monoxide (p &lt; .001), total nicotine equivalents (p = .02), and four out of five measured volatile organic compounds (ps &lt; .01) over time among the CS group. Exposure to N′-nitrosonornicotine increased by trial end only among the PS group (p &lt; .04). Phenanthrene tetraol increased among all groups by trial end (p = .02) with no difference between groups. Conclusions Instructions to completely switch from cigarettes to snus resulted in the greatest reduction in cigarettes and exposure to harmful constituents. Implications Directly instructing smokers to switch completely to snus, rather than using ad libitum (with no instructions to avoid cigarettes), is necessary for reductions in smoking and subsequent exposure to harmful constituents.

Psychotomimetic Effects

BackgroundCannabis and tobacco have contrasting cognitive effects. Smoking cannabis with tobacco is prevalent in many countries and although this may well influence cognitive and mental health outcomes, the possibility has rarely been investigated in human experimental psychopharmacological research.MethodThe individual and interactive effects of cannabis and tobacco were evaluated in 24 non-dependent cannabis and tobacco smokers in a randomized, placebo-controlled, double-blind, 2 (cannabis, placebo) × 2 (tobacco, placebo) crossover design. Verbal memory (prose recall), working memory (WM) performance including maintenance, manipulation and attention (N-back), psychotomimetic, subjective and cardiovascular measures were recorded on each of four sessions.ResultsCannabis alone impaired verbal memory. A priori contrasts indicated that tobacco offset the effects of cannabis on delayed recall. However, this was not supported by linear mixed model analysis. Cannabis load-dependently impaired WM. By contrast, tobacco improved WM across all load levels. The acute psychotomimetic effects and ratings of ‘stoned’ and ‘dizzy’ induced by cannabis were not altered by tobacco. Cannabis and tobacco had independent effects on increasing heart rate and interacting effects on increasing diastolic blood pressure.ConclusionsRelative to placebo, acute cannabis impaired verbal memory and WM. Tobacco enhanced performance on WM, independently of cannabis. Moreover, we found some preliminary evidence that tobacco may offset the effects of cannabis on delayed, but not immediate, verbal recall. In contrast, the psychotomimetic and subjective effects of cannabis were unaffected by tobacco co-administration. By reducing the cognitive impairment from cannabis, tobacco co-administration may perpetuate use despite adverse health consequences.

ObjectiveTo test a possible benefit of dalfampridine on information processing speed (IPS), a key function for cognitive impairment (CogIm) in multiple sclerosis (MS).MethodsIn this randomized, double-blind, placebo-controlled trial, we included patients with a score on the Symbol Digit Modalities Test (SDMT) under the 10th percentile of the reference value. Patients were randomized in a 2:1 ratio to receive dalfampridine 10 mg or placebo twice daily for 12 weeks. They underwent a comprehensive neuropsychological evaluation at screening (T0), at the end of treatment (T1), and after a 4-week follow-up (T2). The primary endpoint was improvement in SDMT.ResultsOut of 208 patients screened, 120 were randomized to receive either dalfampridine (n = 80) or placebo (n = 40). At T1, the dalfampridine group presented an increase of SDMT scores vs placebo group (mean change 9.9 [95% confidence interval (CI) 8.5–11.4] vs 5.2 [95% CI 2.8–7.6], p = 0.0018; d = 0.60 for raw score; and 0.8 [95% CI 0.6–1] vs 0.3 [95% CI 0.0–0.5], p = 0.0013; d = 0.61 for z scores; by linear mixed model with robust standard error). The improvement was not sustained at T2. A beneficial effect of dalfampridine was observed in the Paced Auditory Serial Addition Test and in cognitive fatigue.ConclusionDalfampridine could be considered as an effective treatment option for IPS impairment in MS.Trial registration2013-002558-64 EU Clinical Trials Register.Classification of evidenceThis study provides Class I evidence that for patients with MS with low scores on the SDMT, dalfampridine improves IPS.

The Impact

The aim of this randomized controlled trial was to evaluate the impact of a novel 8-week coach development intervention (MASTER) on game-based coaching practices of netball coaches from one netball club (n = 16; 8 intervention, 8 active-control; NSW Australia), and player outcomes for the junior athletes being coached. The multi-component MASTER intervention aimed to educate coaches on how to design and implement high quality game-based coaching sessions. The core pillar of MASTER is ‘positive coaching,’ delivered through games-based coaching practices. At baseline and 10-weeks, two coaching sessions per coach were filmed and assessed using the MASTER assessment tool. Players (8-16yrs; n = 85) were videoed during structured gameplay, with three aspects of game play assessed using Game Performance Assessment Instrument. Coaches and players (n = 75; 12-16yrs) completed a perceptions questionnaire. Using linear mixed model ITT analysis, significant interventions effects were observed for the primary outcome: percentage of time spent performing playing-form activities [25.7% (95% CI (7.79-43.65), P = 0.008, d = 1.52]. Significant interventions effects were also observed for coach perceptions, player game skills, and player self-perceptions (P < 0.05). No significant changes were observed for player enjoyment, motivation, or wellbeing. The MASTER program was effective in improving coach and player self-perceptions, and coaching practices of netball coaches during training sessions.
