BACKGROUND Unintentional injuries are a major public health problem to children worldwide. With the widespread use of smartphones in China, social networking mobile applications, such as WeChat, are potential ways to implement parent-based interventions. OBJECTIVE This study aimed to evaluate the effectiveness of WeChat group-based parental intervention programs in preventing unintentional injuries in children aged 0–3 years in China. METHODS We conducted a randomized controlled trial from March 2019 to March 2020. A total of 365 parents of children aged 0–3 years in Shanghai were randomly allocated to intervention and control groups, and 276 participants completed the follow-up. We used generalized estimation equations to assess intervention effectiveness at baseline and after one year. Outcome measures included children’s unintentional injury incidences, parents’ knowledge, attitudes, and behaviors. RESULTS During the one year follow-up, unintentional injury incidences increased from 9.00% to 11.70% in the intervention group and from 9.90% to 22.90% in the control group. The changes did not differ between the groups (odds ratio [OR] 0.67, 95% confidence interval [CI] 0.13-3.48). Changes in the parents’ attitudes toward injury attribution (b 0.10, 95% CI 0.09-0.21) and preventability (b 0.16, 95% CI 0.01-0.33) did not differ between the two groups. Changes in parents’ attitudes toward responsibility in the intervention group were greater than those in the control group (b 0.33, 95% CI 0.15, 0.51). Changes in parents' daily supervision behavior in the intervention group was greater than those in the control group (b 0.43, 95% CI 0.02-0.84), and changes in behaviors of preventing specific injuries were significantly different between the groups (b 1.60, 95% CI 1.05-2.16). CONCLUSIONS Although WeChat group-based parental intervention cannot directly reduce the occurrence of children’s unintentional injuries, it can improve parents’ knowledge, attitudes, and behaviors pertaining to prevention of unintentional injuries.

Background App-based interventions have the potential to reduce child injury in countries with limited prevention resources, but their effectiveness has not been rigorously examined. Objective This study aimed to assess the effectiveness of an app-based intervention for caregivers of preschoolers to prevent unintentional injury among Chinese preschoolers. Methods A 6-month cluster randomized controlled trial was conducted from December 2017 to June 2018. Recruitment was conducted through preschools, which were randomly allocated to either the control group (ie, app-based parenting education excluding unintentional injury prevention) or the intervention group (ie, app-based parenting education including unintentional injury prevention). A total of 2920 caregivers of preschoolers aged 3-6 years from 20 preschools in Changsha, China, were recruited offline through the schools. The primary outcome was unintentional injury incidences among preschoolers in the past 3 months; this measure was assessed through an online caregiver-report at the baseline visit and at 3-month and 6-month follow-up visits. Secondary outcome measures included caregivers’ self-reported attitudes and behaviors concerning child supervision during the last week. Generalized estimating equations (GEEs) were used to assess the effectiveness of the app-based intervention on responses at 3 and 6 months after adjusting for sociodemographic variables, baseline level of the outcome variable, and engagement with interventions in the assigned group. All analyses were intention-to-treat. A per-protocol sensitivity analysis was also conducted. Results In total, 1980 of the 2920 caregivers completed the study. The mean age of participants was 32.0 years (SD 5.5) and 68.99% (1366/1980) of them were female. During the 6-month follow-up visit, unintentional injury incidence did not change significantly in either group: incidence in the intervention group went from 8.76% (94/1073) to 8.11% (87/1073), P=.59; incidence in the control group went from 9.4% (85/907) to 7.5% (69/907), P=.15. The changes did not differ between the groups (odds ratio [OR] 1.14, 95% CI 0.80-1.62). Changes in the average score in attitude concerning unintentional injury prevention were also similar between the groups (B .05, 95% CI -0.03 to 0.13). Changes in unintentional injury prevention behaviors were greater in the intervention group than in the control group after the intervention (B .87, 95% CI 0.33-1.42). Analyses of individual injury prevention behaviors showed that the intervention reduced three risky behaviors: unsafe feeding of children (OR 0.73, 95% CI 0.60-0.89); incorrectly placing children in cars (OR 0.73, 95% CI 0.57-0.93); and allowing children to ride bicycles, electric bicycles, or motorcycles unsupervised (OR 0.80, 95% CI 0.64-0.99). The intervention also improved scores on three safety-focused behaviors: testing water temperature before giving children a bath (OR 1.26, 95% CI 1.05-1.52); properly storing sharp objects (OR 1.24, 95% CI 1.01-1.52); and safely storing medicines, detergents, and pesticides (OR 1.24, 95% CI 1.02-1.51). Conclusions The app-based intervention did not reduce unintentional injury incidence among preschoolers but significantly improved caregivers’ safety behaviors. This app-based intervention approach to improve caregiver behaviors surrounding child injury risk offers promise to be modified and ultimately disseminated broadly.

The objective of this study was to compare standard treatment versus the combination of intrapancreatic autologous stem cell (ASC) infusion and hyperbaric oxygen treatment (HBOT) before and after ASC in the metabolic control of patients with type 2 diabetes mellitus (T2DM). This study was a prospective, randomized controlled trial. The combined intervention consisted of 10 sessions of HBOT before the intrapancreatic infusion of ASC and 10 sessions afterwards. ASCs were infused into the main arterial supply of the pancreas to maximize the presence of the stem cells where the therapeutic effect is most desired. A total of 23 patients were included (control group = 10, intervention group = 13). Age, gender, diabetes duration, number of medications taken, body weight and height, and insulin requirements were recorded at baseline and every three months. Also, body mass index, fasting plasma glucose, C-peptide, and HbA1c, C-peptide/glucose ratio (CPGR) were measured every three months for one year. HbA1c was significantly lower in the intervention group compared with control throughout follow-up. Overall, 77% of patients in the intervention group and 30% of patients in the control group demonstrated a decrease of HbA1c at 180 days (compared with baseline) of at least 1 unit. Glucose levels were significantly lower in the intervention group at all timepoints during follow-up. C-peptide levels were significantly higher in the intervention group during follow-up and at one year: 1.9 ± 1.0 ng/mL versus 0.7 ± 0.4 ng/mL in intervention versus control groups, respectively, p = 0.0021. CPGR was higher in the intervention group at all controls during follow-up. The requirement for insulin was significantly lower in the intervention group at 90, 180, 270, and 365 days. Combined therapy of intrapancreatic ASC infusion and HBOT showed increased metabolic control and reduced insulin requirements in patients with T2DM compared with standard treatment.

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.

BACKGROUND Mobile health interventions, a more cost-effective approach compared to traditional methods of delivering lifestyle coaching in person, have been shown to improve physical parameters and lifestyle behavior among overweight populations. It is useful to know the efficacy of mobile apps in treating abdominal obesity, as it is a known risk factor for metabolic disorders and type 2 diabetes. OBJECTIVE This study aimed to determine whether a mobile self-management app (DialBeticsLite) could be used by patients with abdominal obesity to achieve a reduction in visceral fat area (VFA) and other physical parameters. METHODS This study was an open-label, 2-arm parallel-design randomized controlled trial. We recruited 122 people in September 2017, and randomly assigned them into either the intervention group or the control group. All participants attended an educational group session, which delivered information regarding diet and exercise. Additionally, participants in the intervention group were asked to use DialBeticsLite for 3 months. DialBeticsLite facilitated the daily recording of several physical parameters and lifestyle behavior, and provided feedback to encourage an improvement in behavior. The primary outcome was the change in VFA from baseline to the 3-month follow-up. Secondary outcomes included changes in both physical and metabolic parameters, from baseline to the 3-month follow-up. Welch t test was conducted to analyze the effects of DialBeticsLite on both the primary outcome and the secondary outcomes. RESULTS Out of the 122 participants recruited, 75 participants were analyzed due to 47 participants being excluded: 37 due to ineligibility and 10 due to withdrawal of consent. The mean age was 49.3 (standard deviation: SD 6.1) in the intervention group (n=41) and 48.5 (SD 5.3) in the control group (n=34), and all participants were male, though unintentionally. Baseline characteristics did not differ significantly between the intervention and control group, except for VFA. The averaged change of VFA was -23.5cm2 (SD 20.6) in the intervention group and +1.9cm2 (SD 16.2) in the control group (P<.001). Statistically significant differences were also found for the change of body weight, BMI and waist circumference. These findings did not change after adjusting for VFA at baseline. The intervention had no significant effect on any of the metabolic parameters. An exploratory analysis showed significant associations between the change in VFA and steps per day, and between the change in VFA and calorie intake per day within the intervention group. CONCLUSIONS Our findings indicate that although unsuccessful in improving metabolic parameters, a mobile health intervention facilitating the daily monitoring of several physical parameters and lifestyle behavior, can be highly effective in inducing visceral fat loss and weight loss among adults with abdominal obesity.

Abstract Background Cardiac rehabilitation (CR) programs are evidence-based and widely recommended. However, benefits from CR are likely lost among individuals who discontinue their regular exercise routines and healthy habits. One possible approach to enhance adherence to lifestyle advice after completion of CR, may be individualized follow-up enabled by a smartphone application (app). Methods A protocol of a single-blinded, pragmatic randomized controlled trial. The study will take place in the eastern part of Norway, and will include heart patients who have completed CR. Participants will be recruited from two CR centers. Based on power calculation, 113 participants will be included. The intervention group will receive individualized follow-up through an app on a weekly basis throughout a year. The app will be set up with the participant’s own goals, and the follow-up will be based on these individual goals. The control group will receive usual care, including general advice regarding physical activity, exercise and diet. The participants will be assessed at baseline (at completion of CR) and 12 months after baseline. Primary outcome of the study will be peak oxygen uptake. Secondary outcomes include exercise performance, quality of life, health status, health literacy, self-perceived goal achievement, exercise habits, body weight, blood pressure as well as lipids and triglycerides. Discussion To our knowledge, this will be the first study to examine the effects of individualized follow-up with an app for one year, in patients completing CR. Hence, it is reasonable to assume that the study may be groundbreaking. Due to the large sample size and the theoretically based intervention, the study has the potential to generate new knowledge that may improve the design of future technology-based follow-up interventions of patients that have completed rehabilitation.

BackgroundAlthough depression is a common problem among non-professional caregivers, only one trial has evaluated the efficacy of indicated prevention targeting this population and the long-term efficacy is unknown. The aim of this study was to evaluate the long-term efficacy of a brief intervention for the indicated prevention of depression in a sample of female caregivers.MethodA randomized controlled trial was conducted involving 173 participants (mean age 53.9 years) who were allocated to the intervention (n = 89) or the usual-care control group (n = 84). Blinded interviewers conducted assessments at 1, 3, 6 and 12 months of follow-up. The main outcome measure was the incidence of major depression and the secondary outcomes were compliance with treatment, depressive symptoms, emotional distress and caregiver burden.ResultsAt the 12-month follow-up, a lower incidence of depression as evaluated using the Structured Clinical Interview for Axis I Disorders of the DSM-IV was found in the intervention group compared with the control group (10.1%v.25.0%). The relative risk was 0.40 and statistically significant [χ2 = 6.68, degrees of freedom = 1,p = 0.010, 95% confidence interval (CI) 0.20–0.81], and the number needed to treat was 7 (95% CI 4–27). There was a significant delay in the onset of depression in the intervention group (p = 0.008). The good complier caregivers had a lower incidence of depression. The intervention effect on depressive symptoms, emotional distress and caregiver burden were maintained for 12 months.ConclusionsThis is the first study to demonstrate that a brief problem-solving intervention can prevent the onset of depression among non-professional caregivers over the longer term.

Background. Stagnation syndrome, a diagnostic entity in traditional Chinese medicine (TCM), is characterized by mind-body obstruction-like symptoms. Although TCM has long-established symptom-relief treatments, a comprehensive mind-body intervention was called for. Purpose. The study evaluated the efficacy of a six-session body-mind-spirit (BMS) group therapy for persons with stagnation syndrome. Method. A 2-arm randomized controlled trial design was adopted. The control group received a parallel general TCM instruction course. Both groups completed a pretest (T0), posttest (T1), and 2-month follow-up assessment (T2). The measures included self-report scales on stagnation, depression, anxiety, physical distress, daily functioning, and positive and negative affect; the other measure was of salivary cortisol, a biological marker of stress. Results. Data on 111 adults with stagnation syndrome were included in the analysis. Completion rates were high (over 87%) for both the intervention and control groups. Repeated-measures multivariate MANOVA revealed a significant combined effect with large effect size (eta-squared = 0.42). Repeated-measures ANOVA further revealed that the intervention group showed significant improvements in stagnation, the primary outcome, with medium effect size (eta-squared = 0.11). The intervention group also showed significant improvements in depression, physical distress, everyday functioning, and negative affect (eta-squared = 0.06 to 0.13). Post hoc analysis revealed that the intervention group showed significant improvements over the control group in cortisol level at 2-month follow-up assessment (T0 versus T2) with small effect size (eta-squared = 0.05), but not at posttest (T0 versus T1). Conclusions. Overall, the findings indicate that our brief BMS group therapy intervention for stagnation syndrome is efficacious. Moreover, the intervention resulted in a number of substantial improvements in the physical and mental health domains.

Medication Information

Background:: Antiretroviral therapy for the management of HIV typically requires the chronic use of 3 or more medications. As such, patients with HIV are required to manage complex dosing schedules and are at risk of multiple potential adverse effects. The use of pictograms on medication vials as a means of improving patients' understanding of medication information has been shown to positively influence understanding and adherence compared to those using text atone. Objective: To determine whether pictograms (Pharmaglyph) increase patient recall of targeted information associated with HIV medications and whether patients can interpret the intended meaning of pictograms that they had not seen previously. Methods: A randomized, controlled trial was conducted in HIV-positive patients aged 19 years or older who were receiving a new prescription for an antiretroviral medication from the ambulatory pharmacy at St. Paul's Hospital in Vancouver, British Columbia, Canada. Participants were randomized to receive either pictogram-enhanced medication information or standard counseling. At the first follow-up visit, each patient's recall of the medication information was evaluated, and differences between groups were compared. Results: Eighty-two subjects were randomized, 40 to the intervention group and 42 to the control arm. The mean (SD) number of HIV medications was nearly equal between the intervention and control groups: 3.0 (1.5) and 3.1 (1.4), respectively. After a mean of 34 days, 33 patients in the intervention arm and 39 in the control arm completed the study. The majority (88%) of the targeted pieces of information in the intervention group were correctly identified at follow-up, compared to only 2% in the control group (Fisher exact test; p < 0.0001). Conclusions: Pictograms improve the recall of targeted medication information among patients receiving antiretroviral therapy for HIV management; however, this appears to be dependent on the fact that these patients received a verbal explanation of each pictogram prior to use.

Although in vivo exposure therapy is highly effective in the treatment of specific phobias, only a minority of patients seeks therapy. Exposure to virtual objects has been shown to be better tolerated, equally efficacious, but the technology has not been made widely accessible yet. We developed an augmented reality (AR) application (app) to reduce fear of spiders and performed a randomized controlled trial comparing the effects of our app (six 30-min sessions at home over a two-week period) with no intervention. Primary outcome was subjective fear, measured by a Subjective Units of Distress Scale (SUDS) in a Behavioural Approach Test (BAT) in a real-life spider situation at six weeks follow-up. Between Oct 7, 2019, and Dec 6, 2019, 66 individuals were enrolled and randomized. The intervention led to significantly lower subjective fear in the BAT compared to the control group (intervention group, baseline: 7·12 [SD 2·03] follow-up: 5·03 [SD 2·19] vs. control group, baseline: 7·06 [SD 2·34], follow-up 6·24 [SD 2.21]; adjusted group difference -1·24, 95% CI -2·17 to -0·31; Cohen’s d=0·57, p=0·01). The repeated use of the AR app reduces subjective fear in a real-life spider situation, providing a low-threshold and low-cost treatment for fear of spiders.
