Purpose: To assess the feasibility of a technology-assisted intervention in a hybrid cardiac rehabilitation program among patients with coronary heart disease. Methods: This study was a two-arm parallel randomized controlled trial. Twenty-eight patients with coronary heart disease were randomly assigned to either the intervention group, receiving a 12-week technology-assisted intervention (n = 14), or the control group (n = 14), receiving usual care. Guided by the Health Belief Model, the intervention group received three center-based, supervised exercise training sessions, a fitness watch that served as a cue to action, six educational videos, and a weekly video call. The Self-efficacy for Exercise, exercise capacity, and Health Promoting Lifestyle Profile II were assessed at baseline and immediately post-intervention (12-weeks). Results: Among the 28 patients who participated in this study, 85.7% completed the program, with a relatively low attrition rate (14.3%). The number of exercise training sessions accomplished by the participants in the intervention group was 51.27 ± 19.41 out of 60 sessions (85.5%) compared to 36.46 ± 23.05 (60.8%) in the control group. No cardiac adverse events or hospitalizations were reported throughout the study. Participants in the intervention group showed greater improvement in health-promoting behaviors when compared with the control group at 12 weeks. Within-group effects demonstrated improvement in exercise self-efficacy and exercise capacity among participants in the intervention group. A participant satisfaction survey conducted immediately post-intervention revealed that participants were “very satisfied” (23.1%) and “satisfied” (76.9%) with the technology-assisted intervention. Conclusions The findings demonstrated that technology-assisted intervention in a hybrid cardiac rehabilitation program was feasible and suggested to be beneficial in improving exercise self-efficacy, exercise capacity, and health promoting behavior among patients with coronary heart disease. A full-scale study is needed to determine its effectiveness in the long term.

BACKGROUND: Eczema is the most common skin problem among children in Hong Kong. Previous studies have highlighted that the quality of life of the families of children with eczema influences the effects of eczema interventions. However, the Chinese version of the Family Dermatology Life Quality Index (C-FDLQI), a tool for measuring the quality of life of the families of children with eczema, has not yet been validated. OBJECTIVE: This study examined the psychometric properties of the C-FDLQI among parents and caregivers of children with eczema in Hong Kong. METHODS: This study evaluated the internal consistency, test-retest reliability and structural validity of the C-FDLQI and its convergent validity by examining its correlations with the SCORing Atopic Dermatitis (SCORAD) and the Cantonese version of the Children’s Dermatology Life Quality Index (C-CDLQI) among 147 Chinese parents/caregivers of children with varying degrees of eczema.

Purpose: The purpose of this study was to translate the original English version of the Physical SelfPerception Profile into Cantonese Chinese, while considering linguistic and socio-cultural characteristics, and to evaluate its psychometric properties among Chinese breast cancer survivors in Hong Kong, China, thus providing a valid, culturally relevant tool for assessing physical self-esteem among this population. Methods: The 30-item, 5 subscale Physical Self-Perception Profile was translated into Chinese by the combined translation technique. The psychometric properties of the Cantonese version of the Physical Self-Perception Profile were examined in 292 Hong Kong Chinese breast cancer survivors for internal consistency and testeretest reliability. A confirmatory factor analysis was conducted to evaluate the structural validity. A panel of five experts examined its content validity. The concurrent validity was examined by correlating the Physical Self-Perception Profile and a validated global self-esteem measure. Results: The Cantonese version of the Physical Self-Perception Profile demonstrated satisfactory content validity, also satisfactory internal consistency with Cronbach's a ranging from .64 to .80, as well as good testeretest reliability, with an intraclass correlation coefficient ranging from .77 to .81. The confirmatory factor analysis showed a fairly good fit of the four-factor subdomain structure, namely, physical condition, physical strength, body attractiveness, and sports competence. The concurrent validity of the Chinese version Physical Self-Perception Profile was demonstrated by a significant positive correlation between the physical self-worth domain and four subdomains with global self-esteem. In addition, the four subdomains had statistically significant positive correlations, with the physical self-worth domain indicating the instrument's hierarchical structure. Conclusion The study translated the Physical Self-Perception Profile from English to Cantonese and demonstrated its desirable psychometric properties among Chinese Hong Kong breast cancer survivors.The linguistical and cultural adaptation of this instrument can serve as a valid and reliable tool for assessing physical self-esteem among breast cancer survivors in Hong Kong, China.

PURPOSE: The aim of this study was to validate a computational fluid dynamics (CFD) simulation of flow-diverter treatment through Doppler ultrasonography measurements in patient-specific models of intracranial bifurcation and side-wall aneurysms. METHODS: Computational and physical models of patient-specific bifurcation and sidewall aneurysms were constructed from computed tomography angiography with use of stereolithography, a three-dimensional printing technology. Flow dynamics parameters before and after flow-diverter treatment were measured with pulse-wave and color Doppler ultrasonography, and then compared with CFD simulations. RESULTS: CFD simulations showed drastic flow reduction after flow-diverter treatment in both aneurysms. The mean volume flow rate decreased by 90% and 85% for the bifurcation aneurysm and the side-wall aneurysm, respectively. Velocity contour plots from computer simulations before and after flow diversion closely resembled the patterns obtained by color Doppler ultrasonography. CONCLUSION: The CFD estimation of flow reduction in aneurysms treated with a flow-diverting stent was verified by Doppler ultrasonography in patient-specific phantom models of bifurcation and side-wall aneurysms. The combination of CFD and ultrasonography may constitute a feasible and reliable technique in studying the treatment of intracranial aneurysms with flow-diverting stents.
