Objective: This study investigates the psychometric properties of the Dutch version of the Ghent University Classroom Coding Inventory (GUCCI-NL) by comparing children with (subthreshold) ADHD to typically developing peers. The advantage of the GUCCI is that it measures the proportion of time ADHD behavior was displayed and length of such intervals in a continuous manner that allows for more detailed assessment of behavior, such as on-task span, compared to traditional time sampling methods.Method: We coded the scales Attention Problems, Motor and Verbal Hyperactivity, and Oppositional Behavior in a sample of 57 children with (subthreshold) ADHD and 34 controls (aged 6–12). Construct validity (i.e., group differences, convergent and divergent validity), predictive validity (including ROC curves), and inter-observer reliability were investigated. Outcome measures were percentage of time and interval span. Results: The GUCCI-NL discriminated between the ADHD and control group for all scales (small to very large effects), with largest effects on percentage of time. Convergent validity against questionnaire and interview scores was confirmed for Verbal Hyperactivity and Oppositional Behavior, although divergent validity was weak. The Attention Problems scale was most sensitive to group membership (AUC = .79). Inter-observer reliability was sufficient (r >.82). Group differences on span length were found for Attention Problems but not for Hyperactivity, confirming the additional value of continuous coding.Conclusion: The GUCCI-NL is a valid objective measure for ADHD symptoms in the classroom, which may be of added value in scientific practice, although for diagnostic purposes additional instruments should be used.

AbstractThe psychometric properties of a Binocular Rivalry (BR)-based test on a group of 159 participants (57 with attention deficit hyperactivity disorder, ADHD) aged between 6 and 15 years are presented. Two factors, which explained 56.82% of the variance, were obtained by exploratory factor analysis: (a) Alternations and Duration of exclusive dominances, and (b) Decision time. Reliability was excellent (Cronbach’s α = .834 and .884). The ADHD group showed fewer alternations and longer duration of dominances and decision time than the control group. Correlations between measures of BR, IQ, working memory, and processing speed of the WISC-IV, and ADHD symptoms, assessed by parents and teachers, ranged between low and medium.

Objectives: To investigate the psychometric properties of the reflux symptom index (RSI) as short screening approach for the diagnostic of laryngopharyngeal reflux (LPR) in patients with confirmed diagnosed regarding the 24-hour multichannel intraluminal impedance-pH monitoring (MII-pH). Methods: From January 2017 to December 2018, 56 patients with LPR symptoms and 71 healthy individuals (control group) were prospectively enrolled. The LPR diagnosis was confirmed through MII-pH results. All subjects (n = 127) fulfilled RSI and the Reflux Finding Score (RFS) was performed through flexible fiberoptic endoscopy. The sensitivity and the specificity of RSI was assessed by ROC (Receiver Operating Characteristic) analysis. Results: A total of 15 LPR patients (26.8%) of the clinical group met MII-pH diagnostic criteria. Among subjects classified as positive for MII- pH diagnoses, RSI and RFS mean scores were respectively 20 (SD ± 10.5) and 7.1 (SD ± 2.5), values not significantly different compared to the negative MII-pH group. The metric analysis of the items led to the realization of a binary recoding of the score. Both versions had similar psychometric properties, α was 0.840 for RSI original version and 0.836 for RSI binary version. High and comparable area under curve (AUC) values indicate a good ability of both scales to discriminate between individuals with and without LPR pathology diagnosis. Based on balanced sensitivity and specificity, the optimal cut-off scores for LPR pathology were ≥ 5 for RSI binary version and ≥ 15 for RSI original version. Both version overestimated LPR prevalence. The original version had more sensitivity and the RSI Binary version had more specificity. Conclusions: It would be necessary to think about modifying the original RSI in order to improve its sensitivity and specificity (RSI binary version, adding or changing some items), or to introduce new scores in order to better frame the probably affected of LPR patient.

Background: Environmental enrichment involves organisation of the environment and provision of equipment to facilitate engagement in physical, cognitive and social activity. In animals with stroke, it promotes brain plasticity and recovery. Aims: To assess the feasibility and safety of a patient-driven model of environmental enrichment incorporating access to communal and individual environmental enrichment. Methods: A non-randomised cluster trial with blinded measurement involving people with stroke (n=193) in 4 rehabilitation units was carried out. Feasibility was operationalised as activity 10 days after admission to rehabilitation and availability of environmental enrichment. Safety was measured as falls and serious adverse events. Benefit was measured as clinical outcomes at 3 months, by an assessor blinded to group. Results: The experimental group (n=91) spent 7% (95% CI -14 to 0) less time inactive, 9% (95% CI 0 to 19) more time physically, and 6% (95% CI 2 to 10) more time socially active than the control group (n=102). Communal environmental enrichment was available 100% of the time, but individual environmental enrichment was rarely within reach (24%) or sight (39%). There were no between-group differences in serious adverse events or falls at discharge or 3 months nor in clinical outcomes at 3 months. Conclusions: This patient-driven model of environmental enrichment was feasible and safe. However, the very modest increase in activity by people with stroke, and the lack of benefit in clinical outcomes 3 months after stroke do not provide justification for an efficacy trial.

Chronic obstructive pulmonary disease (COPD) patients are characterised for presenting dyspnea, which reduces their physical capacity and tolerance to physical exercise. The aim of this study was to analyse the effects of adding a Feel-Breathe (FB) device for inspiratory muscle training (IMT) to an 8-week pulmonary rehabilitation programme. Twenty patients were randomised into three groups: breathing with FB (FBG), oronasal breathing without FB (ONBG) and control group (CG). FBG and ONBG carried out the same training programme with resistance, strength and respiratory exercises for 8 weeks. CG did not perform any pulmonary rehabilitation programme. Regarding intra group differences in the value obtained in the post-training test at the time when the maximum value in the pre-training test was obtained (PostPRE), FBG obtained lower values in oxygen consumption (VO2, mean = −435.6 mL/min, Bayes Factor (BF10) > 100), minute ventilation (VE, −8.5 L/min, BF10 = 25), respiratory rate (RR, −3.3 breaths/min, BF10 = 2), heart rate (HR, −13.7 beats/min, BF10 > 100) and carbon dioxide production (VCO2, −183.0 L/min, BF10 = 50), and a greater value in expiratory time (Tex, 0.22 s, BF10 = 12.5). At the maximum value recorded in the post-training test (PostFINAL), FBG showed higher values in the total time of the test (Tt, 4.3 min, BF10 = 50) and respiratory exchange rate (RER, 0.05, BF10 = 1.3). Regarding inter group differences at PrePOST, FBG obtained a greater negative increment than ONBG in the ventilatory equivalent of CO2 (EqCO2, −3.8 L/min, BF10 = 1.1) and compared to CG in VE (−8.3 L/min, BF10 = 3.6), VCO2 (−215.9 L/min, BF10 = 3.0), EqCO2 (−3.7 L/min, BF10 = 1.1) and HR (−12.9 beats/min, BF10 = 3.4). FBG also showed a greater PrePOST positive increment in Tex (0.21 s, BF10 = 1.4) with respect to CG. At PreFINAL, FBG presented a greater positive increment compared to CG in Tt (4.4 min, BF10 = 3.2) and negative in VE/VCO2 intercept (−4.7, BF10 = 1.1). The use of FB added to a pulmonary rehabilitation programme in COPD patients could improve tolerance in the incremental exercise test and energy efficiency. However, there is only a statically significant difference between FBG and ONBG in EqCO2. Therefore, more studies are necessary to reach a definitive conclusion about including FB in a pulmonary rehabilitation programme.

The Mean

Background:Clinical practice guidelines recommend that exercise is an essential component in the self-management of Ankylosing Spondylitis (AS). Attending supervised interventions requiring periodic medical center visits can be burdensome and patients may decline participation, whereas, effective home-based exercise interventions that do not need regular medical center visits are likely to be more accessible and acceptable for patients with AS. Recently, increasing evidences have been accumulated that the wearable devices could facilitate patients with inflammatory arthritis by giving exercise instructions and improving self-efficacy. Therefore, patients with AS may benefit from an effective technology-assisted home-based exercise intervention.Objectives:To investigate the efficacy of a comprehensive technology-assisted home-based exercise intervention on disease activity in patients with AS.Methods:This study was a 16-week assessor-blinded, randomized, waiting-list controlled trial (ChiCTR1900024244). Patients with AS were randomly allocated to the home-based exercise intervention group and the waiting-list control group. A 16-week comprehensive exercise program consisting of a moderate intensity (64%-76% HRmax) aerobic training for 30min on 5 days/week and a functional training for 60min on 3 days/week was given to patients in the intervention group immediately after randomization, with 1.5h training sessions for two consecutive days by a study physical therapist at baseline and Week 8. The aerobic exercise intensity was controlled by a Mio FUSE Wristband with a smartphone application. The functional training consisted of the posture training, range of motion exercises, strength training, stability training and stretching exercises. Patients in control group received standard care during the 16-week follow-up and started to receive the exercise program at Week 16. The primary outcome was ASDAS at Week 16. The secondary outcomes were BASDAI, BASFI, BASMI, ASAS HI, peak oxygen uptake, body composition and muscle endurance tests. The mean difference between groups in change from baseline was analyzed with the analysis of covariance.Results:A total of 54 patients with AS were enrolled (26 in intervention group and 28 in control group) and 46 (85.2%) patients completed the 16-week follow-up. The mean difference of ASDAS between groups in change from baseline to 16-week follow-up was −0.2 (95% CI, −0.4 to 0.003, P = 0.032), and the mean change from baseline was -0.4 (95% CI, -0.5 to -0.2) in the intervention group vs -0.1 (95% CI, -0.3 to 0.01) in the control group, respectively. Significant between-group differences were found between groups for BASDAI (−0.5 [95% CI, −0.9 to −0.2], P = 0.004), BASMI (−0.7 [95% CI, −1.1 to −0.4], P <0.001), BASFI (−0.3 [95% CI, −0.6 to 0.01], P=0.035), peak oxygen uptake (2.7 [95% CI, 0.02 to 5.3] ml/kg/min, P=0.048) and extensor endurance test (17.8 [95% CI, 0.5 to 35.2]s, P=0.044) at Week 16. Between-group differences were detected in ASAS HI (−0.9 [95% CI, −1.7 to −0.1], P=0.030), body fat percentage (−1.0 [95% CI, −2.0 to −0.01] %, P=0.048) and visceral adipose tissue (−4.9 [95% CI, −8.5 to −1.4] cm2, P=0.008) at Week 8, but not at Week 16. No significant between-group differences were detected in the total lean mass, time up and go test and the flexor endurance test during the follow-up.Conclusion:Comprehensive technology-assisted home-based exercise has been shown to have beneficial effects on disease activity, physical function, spinal mobility, aerobic capacity, and body composition as well as in improving fatigue and morning stiffness of patients with AS.References:[1]van der Heijde D, Ramiro S, Landewé R, et al.

Community Dwelling Older Adults

Older adults’ physical activity (PA) is low. We examined whether eight months of resistance training increased PA level in community-dwelling older adults receiving home care. A two-armed cluster-randomized trial using parallel groups was conducted. The included participants were >70 years and received home care. The resistance training group performed resistance training using body weight, elastic bands, and water canes twice per week for eight months. The control group was informed about the national PA guidelines and received motivational talks. The ActiGraph GT3X+ accelerometer was used to estimate PA. Outcomes included total PA (counts per minute), sedentary behavior (min/day), light PA (min/day), moderate-to-vigorous PA (min/day), and steps (mean/day). Between-group differences were analyzed using multilevel linear mixed models. Twelve clusters were randomized to either resistance training (7 clusters, 60 participants) or the control group (5 clusters, 44 participants). A total of 101 participants (median age 86.0 (interquartile range 80–90) years) had valid accelerometer data and were included in the analysis. There were no statistically significant between-group differences for any of the PA outcomes after four or eight months. This study offers no evidence of increased PA level following resistance training in older adults with home care.

AbstractThe majority of individuals with problematic and pathological gambling remain untreated, and treatment barriers are high. Internet-based interventions can help to address existing barriers, and first studies suggest their potential for this target group. Within a randomized controlled trial (N = 150) with two assessment times (baseline and post-intervention), we aimed to investigate the feasibility, acceptance, and effectiveness of a self-guided Internet-based intervention targeted at gambling problems. We expected a significant reduction in gambling symptoms (primary outcome) and depressive symptoms as well gambling-specific dysfunctional thoughts (secondary outcomes) in the intervention group (IG) compared to a wait-list control group with access to treatment-as-usual (control group, CG) after the intervention period of 8 weeks. Results of the complete cases, per protocol, intention-to-treat (ITT), and frequent user analyses showed significant improvements in both groups for primary and secondary outcomes but no significant between-group differences (ITT primary outcome, F(1,147) = .11, p = .739, ηp2 < .001). Moderation analyses indicated that individuals in the IG with higher gambling and depressive symptoms, older age, and comorbid anxiety symptoms showed significant improvement relative to the CG. The intervention was positively evaluated (e.g., 96.5% rated the program as useful). Possible reasons for the nonsignificant between-group differences are discussed. Future studies should include follow-up assessments and larger samples to address limitations of the present study.

Abstract Objectives We previously reported that random assignment of scientific articles to a social media exposure intervention did not have an effect on article downloads and citations. In this paper, we investigate whether longer observation time after exposure to a social media intervention has altered the previously reported results. Methods For articles published in the International Journal of Public Health between December 2012 and December 2014, we updated article download and citation data for a minimum of 24-month follow-up. We re-analysed the effect of social media exposure on article downloads and citations. Results There was no difference between intervention and control group in terms of downloads (p = 0.72) and citations (p= 0.30) for all papers and when we stratified by open access status. Conclusions Longer observation time did not increase the relative differences in the numbers of downloads and citations between papers in the social media intervention group and papers in the control group. Traditional impact metrics based on citations, such as impact factor, may not capture the added value of social media for scientific publications.
