IntroductionExcessive and insufficient sun exposure during childhood have been linked to serious diseases in later life; for example, insufficient sun exposure during childhood may increase the risk of developing myopia. The Kidskin-Young Adult Myopia Study (K-YAMS) is a follow-up of participants in the Kidskin Study, a non-randomised controlled trial that evaluated the effect of a 4-year educational intervention on sun-protection behaviours among primary school children in the late 1990s. Children who received the Kidskin intervention had lower levels of sun exposure compared with peers in the control group after 2 and 4 years of the intervention, but this was not maintained 2  years after the intervention had ceased. Thus, a follow-up of Kidskin Study participants provides a novel opportunity to investigate the associations between a childhood sun-exposure intervention and potentially related conditions in adulthood.Methods and analysisThe K-YAMS contacts Kidskin Study participants and invites them to participate using a variety of methods, such as prior contact details, the Australian Electoral Roll and social media. Self-reported and objective measures of sun-exposure and sun-protection behaviours are collected as well as a number of eye measurements including cycloplegic autorefraction and ocular biometry. Data will be analysed to investigate a possible association between myopic refractive error and Kidskin intervention group or measured sun exposure.Ethics and disseminationThe K-YAMS is approved by the Human Research Ethics Committee of the University of Western Australia (RA/4/1/6807). Findings will be disseminated via scientific journals and conferences.Trial registration numberACTRN12616000812392; Pre-results.

Abstract Background People increase their risk of melanoma unless they are protected from the harmful effects of sun exposure during childhood and adolescence. We aimed to assess the feasibility of a three-component sun protection intervention- presentation, action planning, and SMS messages - and trial parameters. Methods This feasibility wait-list trial was conducted in the United Kingdom in 2018. Students aged 13-15 years were eligible. Feasibility outcomes were collected for recruitment rates; data availability rates for objective measurements of melanin and erythema using a Mexameter and self-reported sunburn occurrences, severity and body location, tanning, sun protection behaviours and Skin Self-Examination (SSE) collected before (baseline) and after the school summer holidays (follow-up); intervention reach, adherence, perceived impact and acceptability. Quantitative data were analysed using descriptive statistics; qualitative data were analysed thematically. Results Five out of eight schools expressing an interest in participating with four allocated to act as intervention and one control. Four parents/carers opted their child out of the study. 487 out of 724 students on the school register consented to the study at baseline (67%). 385 were in intervention group schools. Objective skin measurements were available for 255 (66%) of the intervention group at baseline and 237 (61%) of the group at follow up. Melanin increased; erythema decreased. Complete self-report data were available for 247 (64%) students in the intervention group. The number of students on the school register who attended the presentation and given the booklet was 379 (98%) and gave their mobile phone number was 155 (40%). No intervention component was perceived as more impactful on sun protection behaviours. Adolescents did not see the relevance of sun protection in the UK or for their age group. Conclusions This is the first study to use a Mexameter to measure skin colour in adolescents. Erythema (visible redness) lasts no more than three days and its measurement before and after a six week summer holiday may not yield relevant or meaningful data. A major challenge is that adolescents do not see the relevance of sun protection and SSE.

Abstract Background Community-dwelling older persons with cognitive impairment (CI) following discharge from geriatric rehabilitation are at high risk of losing life-space mobility (LSM). Interventions to improve their LSM are, however, still lacking. The aim of this study was to evaluate the effects of a CI-specific, home-based physical training and activity promotion program on LSM. Methods Older persons with mild-to-moderate CI (Mini-Mental State Examination: 17–26 points) discharged home from rehabilitation were included in this double-blinded, randomized, placebo-controlled trial with a 12-week intervention period and 12-week follow-up period. The intervention group received a CI-specific, home-based strength, balance, and walking training supported by tailored motivational strategies. The control group received a placebo activity. LSM was evaluated by the Life-Space Assessment in Persons with Cognitive Impairment, including a composite score for LSM and 3 subscores for maximal, equipment-assisted, and independent life space. Mixed-model repeated-measures analyses were used. Results One hundred eighteen participants (82.3 ± 6.0 years) with CI (Mini-Mental State Examination: 23.3 ± 2.4) were randomized. After the intervention, the home-based training program resulted in a significant benefit in the Life-Space Assessment in Persons with Cognitive Impairment composite scores (b = 8.15; 95% confidence interval: 2.89–13.41; p = .003) and independent life-space subscores (b = 0.39; 95% confidence interval: 0.00–0.78; p = .048) in the intervention group (n = 63) compared to control group (n = 55). Other subscores and follow-up results were not significantly different. Conclusions The home-based training program improved LSM and independent life space significantly in this vulnerable population. Effects were not sustained over the follow-up. The program may represent a model for improved transition from rehabilitation to the community to prevent high risk of LSM restriction.

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.

Pediatric clinical trials allow for the testing of appropriate and effective treatments for children. However, some challenges exist with recruitment. This study examined the effectiveness of DigiKnowIt News, an interactive, multimedia website (which includes activities, videos, and comic books) designed to educate children about clinical trials. A randomized controlled trial was conducted in 2018 with 91 participants ( M age = 10.92 years; SD = 2.06). Participants were randomly assigned to intervention or wait-list control groups and completed questionnaires at pretest and posttest (1 week later) about their knowledge, attitudes, beliefs about clinical trials, and self-efficacy for participating in clinical trials. Participants in the intervention group received access to DigiKnowIt News between pretest and posttest and completed a satisfaction questionnaire at posttest. At the end of the study, participants in the wait-list control group were offered the option to use the website and complete a satisfaction questionnaire. At posttest, participants in the intervention group, compared to participants in the wait-list control group, had more knowledge about clinical trials and more reported confidence for participating in clinical trials. Participants reported high levels of satisfaction with DigiKnowIt News. The findings suggest that an educational website can improve factors related to increasing rates of participation in clinical trials.

In order to understand if a physician prescribed medical information changes, the number of hospital readmission, and death among the heart failure patients. A 12-month randomized controlled trial was conducted (December 2013–2014). Totally, 120 patients were randomly allocated into two groups of intervention ( n = 60) and control ( n = 60). Accordingly, the control group was given the routine oral information by the nurse or physician, and the intervention group received the Information Prescription (IP) prescribed by the physician as well as the routine oral information. The data was collected via telephone interviews with the follow-up intervals of 6 and 12 months, and also for 1 year after the discharge. The patients with the median age of (IQR) 69.5 years old (19.8) death upon adjusting a Cox survival model, [RR = 0.67, 95%CI: 0.46–0.97]. Few patients died during 1 year in the intervention group compared to the controls (7 vs 15) [RR = 0.47, 95%CI: 0.20–1.06]. During a period of 6-month follow-up there was not statistically significant on death and readmission between two groups. Physician prescribed information was clinically and statistically effective on the reduction of death and hospital readmission rates among the HF patients in long term follow-up.

Purpose The aim of this study was to identify the effects of a communication skills training (CST) program for oncologists, developed based on patient preferences regarding oncologists' communication. Participants and Methods Thirty oncologists were randomly assigned to either an intervention group (IG; 2-day CST workshop) or control group (CG). Participants were assessed on their communication performance during simulated consultation and their confidence in communicating with patients at baseline and follow-up. A total of 1,192 patients (response rate, 84.6%) who had consultations with the participating oncologists at baseline and/or follow-up were assessed regarding their distress using the Hospital Anxiety and Depression Scale, satisfaction with the consultation, and trust in their oncologist after the consultation. Results At the follow-up survey, the performance scores of the IG had improved significantly, in terms of their emotional support (P = .011), setting up a supportive environment (P = .002), and ability to deliver information (P = .001), compared with those of the CG. Oncologists in the IG were rated higher at follow-up than those in the CG in terms of their confidence in themselves (P = .001). Patients who met with oncologists after they had undergone the CST were significantly less depressed than those who met with oncologists in the CG (P = .027). However, the CST program did not affect patient satisfaction with oncologists' style of communication. Conclusion A CST program based on patient preferences is effective for both oncologists and patients with cancer. Oncologists should consider CST as an approach to enhancing their communication skills.

The Impact

Introduction: Educational programs for children can increase uptake of healthy lifestyle behaviors. However, the impact of educational programs in preschool-aged children in low- and middle-income countries is not known. We conducted a five month educational intervention in preschool facilities (PF) in Bogota, Colombia, to assess changes in preschooler’s knowledge, attitudes and habits (KAH) towards healthy eating and living an active lifestyle. Methods: We conducted a cluster, randomized, controlled trial, and randomly assigned 14 PF in Bogota to a five-month educational intervention (7 PF) or to usual curriculum (7 PF). The intervention included classroom activities and use of printed material and videos. A total of 1216 pre-school children, 928 parents, and 120 teachers participated. A structured survey was used to evaluate changes in KAH with a weighted total score (WTS). The primary outcome was change in children's WTS, and the secondary outcomes were change in parents’ and teachers' WTS. The control PF were provided the intervention after the initial evaluation. To assess sustainability, we evaluated both intervention and control groups at 18 months. Results: At 6 months, children in the intervention group showed 10.9% increase in WTS vs. 5.3% in controls, p<0.001, after adjustment for cluster, sex, age and teachers' educational level. Among parents, the equivalent results were 8.9% and 3.1%, respectively, p< 0.001, and among teachers 9.4% and 2.5%, p=0.06. At the 18-month extended follow-up, both the intervention and control children showed a significant further increase in WTS, p<0.001 (Figure 1). In parents and teachers in the intervened group, there was no significant increase in WTS, p=0.7417, and p=0.1197. In the control group, there was an increase in WTS in teachers but not in parents, p=0.001, and p=0.4239. Conclusion: A preschool based intervention, aimed at changing KAH related to healthy diet and active lifestyle, is feasible, efficacious and sustainable up to 18 months in very young children in Colombia.
