The effects of message framing on self-management behavior among people with type 2 diabetes: A randomized controlled trial.

BACKGROUND: Message framing describes how information is communicated and demonstrated to influence its effect on future attitudes and behaviors. Message content can be structured as 'gain-framed', emphasizing the benefits of engagement as recommended, whereas 'loss-framed' describes the negative consequences of not engaging as recommended. However, the impact of message framing on behavior change in people with chronic diseases like diabetes is not well understood. OBJECTIVE: Analyze the impact of message framing in diabetes education on self-management in people with type 2 diabetes, and identify potential moderating effects of patient activation on message framing. DESIGN: A three-arm randomized controlled trial was performed. SETTING(S): Participants were recruited from inpatients in the endocrine and metabolic unit of a university-affiliated hospital in Changchun. PARTICIPANTS: A total of 84 adults with type 2 diabetes were equally randomized into gain-, loss-, or no-message framing groups and received a 12-week intervention. METHODS: Both the message framing groups received 30 video messages. One group of participants received the gain-framed messages emphasizing desirable outcomes from effective diabetes self-care. The other group of participants received the loss-framed messages emphasizing the undesirable consequences of ineffective diabetes self-care. The control group received 30 videos about diabetes self-care without message framing. Self-management behavior, self-efficacy, patient activation, diabetes knowledge, attitudes, and quality of life were measured at baseline and 12 weeks. RESULTS: Compared with the control group, participants who watched either gain or loss-framed messages had significant increases in self-management behavior and quality of life after the intervention. The scores of self-efficacy, patient activation, knowledge, and attitudes of the loss-framing group were considerably higher than the control group. Further analysis revealed an interaction between patient activation and message framing (P = 0.002), with gain and loss message framing interventions more effective in increasing self-management behaviors in people with type 2 diabetes who had a higher and lower activation level, respectively. CONCLUSIONS: Using message framing in diabetes education is a promising strategy to build and foster self-management behavior. It also suggests that appropriate message framing be chosen to enhance self-management behavior based on the level of patient activation. REGISTRATION NUMBER: ChiCTR2100045772.

Effects of message framing on self-management behaviour among patients with type 2 diabetes: a randomised controlled trial protocol.

INTRODUCTION: Accumulating evidence has indicated successful diabetes health education can potentially help to improve blood sugar levels in people with diabetes. However, with a rapid rise in the number of people with diabetes cases and the increasing burden on healthcare, it is often difficult for healthcare providers to find suitable time to provide health education to meet their needs. Thus, more novel and effective ways are needed to conduct education. The message frame provides a new perspective for implementation of a more effective health education in the form of changing information presentation, and the same objective content is described in either positive or negative language or outcomes. Gain framing emphasises the positive consequences of adhering to useful recommendations, while loss framing highlights the negative consequences of the non-adherence. The purpose of our research is to potentially explore the effectiveness of diabetes education based on message framing on the self-management behaviour. METHODS AND ANALYSIS: A single-blind, three-arm randomised controlled trial involving 84 participants will be conducted. The participants will be assigned into three groups randomly in a 1:1:1 ratio and will receive 12-week intervention. Patients in group 1 will be provided gain framing education videos about the self-management skills for type 2 diabetes, patients in group 2 will be given education videos based on loss framing and patients in group 3 will receive education with no specific message framing. The primary outcome is self-management behaviour. The secondary outcomes will be self-efficacy, patient activation, diabetes-related knowledge and attitude, quality of life and blood glucose level. All outcomes will be measured at baseline and 12 weeks. ETHICS AND DISSEMINATION: This study was approved by the Ethics Committee of School of Nursing, Jilin University (No. 2020101501). The research results will be published in peer-reviewed publications and presented in international conferences. TRIAL REGISTRATION NUMBER: ChiCTR 2100045772; Pre-results.

Effects of Remotely Supervised Physical Activity on Health Profile in Frail Older Adults: A Randomized Controlled Trial Protocol.

Background: Frailty is considered a major public health challenge of the 21st century, characterized by the decline of multiform body functions. Physical activity may be the most effective intervention to delay frailty. This study aims to verify the effect of remotely supervised physical activity on health profile in community-dwelling frail older adults. Design: This is a multicenter, three-blind, two-arm, and cohort randomized controlled study. Methods: The intelligent exercise rehabilitation management system (IERMS) is an integrated digital platform that involves evaluation, guidance, monitoring, and feedback. A total of 120 participants aged ≥ 65 years and diagnosed as frailty on the FRAIL scale will be recruited and randomly divided into two groups. Group 1 will receive a 12-week IERMS-based intervention, and Group 2 will receive the usual care. Data will be collected at baseline, 12 and 24 weeks. The primary outcome is the physical function, and secondary outcomes include gait parameters, psychology, and cognition measurements. Analyses will be performed using DSS statistics, version 25. P < 0.05 will be considered statistically significant. Conclusion: We believe that intervention plays a positive role in delaying the frailty. If our program is effective, we will provide a viable means to promote healthy aging in primary healthcare. Trial registration number: ChiCTR2100052286; Pre-results.

Mobile health-based gamification intervention to increase physical activity participation among patients with coronary heart disease: study protocol of a randomised controlled trial.

INTRODUCTION: Despite proven benefits, physical activity participation remains low in patients with coronary heart disease (CHD). Scientific evidence suggests that mobile health (mHealth)-based gamification interventions could increase physical activity levels. However, several systematic reviews demonstrated that most gamification intervention designs do not appropriately leverage theories from health behaviour models, and empirical evidence on the efficacy of such interventions among patients with CHD is still emerging. This study embeds the principles of behavioural economics into a gamification intervention based on a smartphone app (WeChat applet) to explore whether a mHealth-based gamification intervention can improve participation in physical activity and other related physical and psychological outcomes in patients with CHD. METHODS: We propose a single-blinded three-arm randomised controlled trial with 108 patients with CHD, who will be randomly divided into three groups (Control group: WeChat applet+step goal setting; Individual group: WeChat applet+step goal setting+gamification; Team group: WeChat applet+step goal setting+gamification+collaboration). The interventions will last for 12 weeks and follow-up for 12 weeks. All patients will receive only WeChat applet-based step goal setting in the follow-up period. The primary outcome is physical activity participation, which includes a change in daily steps and self-reported physical activity from the baseline to 12 and 24 weeks, and the proportion of patient-days that step goals achieved in 12 and 24 weeks. The secondary outcomes include biomedical and lifestyle-related risk factors, intrinsic motivation, enjoyment, competence, autonomy and relatedness, social support and mental health and patients' satisfaction, perceptions and intervention experience. ETHICS AND DISSEMINATION: The Human Research Ethics Committee of the School of Nursing, Jilin University (HREC 2020122401) approved this. The results will be published in peer-reviewed journals and presented at conferences. TRIAL REGISTRATION NUMBER: ChiCTR2100044879; Pre-results.

Combined carbon photon and hydrogel therapy mediates the synergistic repair of full-thickness skin wounds.

OBJECTIVE: This study investigated the synergistic repair effects of Prontosan hydrogel and carbon photon therapy in a rat full-thickness wound model. METHODS: The wavelength distribution of the photon source was determined. Dehydration of the Prontosan hydrogel and fibroblast viability were analyzed following exposure to different durations of light exposure at different distances from the source. Indexes of wound healing in a full-thickness rat wound model were then determined in groups (n = 8 each) subjected to either no treatment, Prontosan treatment only, carbon photon therapy only, or a combination of the two treatments (synergistic group). RESULTS: Carbon photon exposure for 15 minutes at a distance of 20 cm from the wound was found to be optimal. Wound healing occurred faster in the synergistic group compared with the control and single-treatment groups. Growth factor secretion, granulation tissue formation, inflammation regulation, collagen deposition, and neovascularization were all higher in the synergistic group. CONCLUSIONS: Prontosan hydrogel combined with carbon photon therapy may provide an optimal environment for wound healing and serve as a novel physical approach to the treatment of wounds. However, the number of animals included in this study was relatively small and a larger study is required to confirm these findings.

Perceptions of smoking cessation among Glasgow's Chinese community.

INTRODUCTION: Health related needs and services are stratified by ethnicity in UK. The Chinese community is Scotland's second-largest minority ethnic group but a relatively under-researched one. This study aimed to explore the views and experiences of smoking cessation and related services among Chinese community members in Glasgow and to inform them about smoking cessation interventions. METHODS: This cross-sectional study was conducted in 2016 using a qualitative research method. Purposive sampling methods were used to recruit 15 Chinese community members in Glasgow. Semi-structured interviews were audio-recorded and data transcribed, translated, and thematically analysed. RESULTS: Many factors influenced participants' smoking: concern for personal health, advice from medical professionals, expenditure, family pressure, tobacco-control policies, nicotine dependence, self-efficacy, and acculturation. Smoking initiation and relapse were influenced by interpersonal relations, emotional factors, Chinese social norms, and acculturation. Barriers reported to accessing and participating in cessation services included: excessive or inflexible working hours, low confidence in cessation services, language barriers, cultural barriers and unsuitability of cessation services for Chinese smokers. Employing community resources, improving language support, working with cultural values, and accommodating degrees of acculturation may improve services and their uptake. CONCLUSIONS: Smoking-cessation services should consider the culture of this ethnic minority population to improve cessation uptake. Further investigation of this community's needs and expectations is needed to tailor smoking-cessation interventions for Chinese immigrants in Glasgow.

Glycol chitosan incorporated retinoic acid chlorochalcone (RACC) nanoparticles in the treatment of Osteosarcoma.

BACKGROUND: Osteosarcoma is the most common of all the bone malignancies and accounts for 30-80% of the primary skeletal sarcomas. The overall survival rate of patients with osteosarcoma is < 20% suggesting poor prognosis. METHODS: The present study demonstrates the effect of retinoic acid chlorochalcone (RACC) incorporated glycol chitosan (GC) nanoparticle transfection in osteosarcoma cells. MG-63 and Saos-2 osteosarcoma cells were transfected with various concentrations of RACC-incorporated GC nanoparticle for 24 h. The effect on cell proliferation, Ezh2 expression, apoptosis, cell cycle arrest, cell migration and invasiveness, Akt phosphorylation and local tumour growth and metastases were studied. RESULTS: MG-63 and Saos-2 osteosarcoma cells on RACC-incorporated GC nanoparticle transfection for 24 h showed a concentration-dependent inhibition of cell proliferation. Of the various concentrations of RACC tested, the effective concentration started from 5 µM with an IC50 of 20 µM. Wound healing assay also showed that RACC-incorporated GC nanoparticles inhibited migration of tumor cells more effectively compared to the parent RA. RACC transfection resulted in inhibition of cell proliferation, Ezh2 expression inhibition, apoptosis through mitochondrial pathway by decrease in membrane potential and release of cytochrome c and cell cycle arrest in the G0/G1 phase. The invasiveness of cells treated with 5 and 20 µM RACC was decreased by 49 and 76% respectively, compared to the control. RACC-treated mice showed significantly lower number of metastases compared to that in the control mice. CONCLUSIONS: Thus, RACC-incorporated glycol chitosan nanoparticle strategy can be promising for the treatment of osteosarcoma.

Accuracy of the lesser trochanter for guiding lag screw insertion in hip fracture management.

The goal of this study was to evaluate the accuracy of the lesser trochanter for entry of lag screw placement in the fixation of hip fractures. Radiographs of the pelvis with both hips in 50 Chinese patients were analyzed to determine the accuracy of using the lesser trochanter as a reference landmark for inserting lag screws. The femoral neck was divided into 4 parts, and the second distal part was classified as the safe zone. Cobb angles of 125° and 130° were used as representative lag screw insertion angles, referencing the lateral cortex of the lesser trochanter for measurement, and insertion tracks were drawn on the neck of the femur. The accuracy of lag screw placement in the defined safe zone was evaluated. Accuracy of placement in the safe zone for entry points at the superior tip, apex, and inferior tip of the lesser trochanter were 78%, 39%, and 0%, respectively, for the 125° Cobb angle. Rates for the superior tip, apex, and inferior tip of the lesser trochanter were 31%, 74%, and 6%, respectively, for the 130° Cobb angle. The entry point at the level of the inferior tip of the lesser trochanter had incidence rates of 95% and 71% for cutout for 125° and 130° screws, respectively. The authors found that the superior tip of the lesser trochanter was a good reference point for 125° lag screw insertion and that the apex of the lesser trochanter was a good reference point for 130° lag screw insertion. Entry at the level of the inferior tip of the lesser trochanter has a very high rate of cutout and should be avoided.

Three-dimensional reconstruction method for measuring the knee valgus angle of the femur in northern Chinese adults.

The purpose of this study was to establish a method for measuring the knee valgus angle from the anatomical and mechanical axes on three-dimensional reconstruction imaging models, and to use this method for estimating an average knee valgus angle value for northern Chinese adults. Computed tomographic angiography data in DICOM format for 128 normal femurs from 64 adult subjects were chosen for analysis. After the femur images were subjected to three-dimensional reconstruction, the deepest point in the intercondylar notch (point A), the midpoint of the medullary cavity 20 cm above the knee-joint line (point B), and the landmark of the femoral head rotation center (point C) were identified on each three-dimensional model. The knee valgus angle was defined as the angle enclosed by the distal femoral anatomical axis (line AB) and the femoral mechanical axis (line AC). The average (mean±SD) of knee valgus angle for the 128 femurs was 6.20°±1.20° (range, 3.05° to 10.64°). Significant positive correlations were found between the knee valgus angles of the right and left sides and between the knee valgus angle and age. During total knee arthroplasty, choosing a valgus cut angle of approximately 6° may achieve a good result in reestablishing the natural mechanical alignment of the lower extremity for patients of northern Chinese ethnicity. Larger valgus cut angles should be chosen for older patients.

Improved method for planning intramedullary guiding rod entry point in total knee arthroplasty.

BACKGROUND: To study the accuracy of using the deepest point of the intercondylar notch (DPIN) as a reference point for femoral intramedullary (IM) guiding rod entrance in total knee arthroplasty (TKA) with 3-D reconstruction in Chinese subjects. METHODS: A total of 50 normal femurs in 25 Chinese subjects (mean age 25.6 ± 2.9 years; range 18-29 years) were chosen from the lower extremities computed tomography digital imaging and communications in medicine (DICOM) database for this study. The DICOM data were imported into Mimics 10.0 software. A cylinder (radius = 4 mm; length = 20 cm) was used to simulate ideal insertion of a IM guiding rod into the femoral canal. DPIN was taken as a reference point for calculating the relative position of the rod's entry point. RESULTS: The mean rod entry point position in the coronal plane was 2.94 ± 1.12 mm (range 0.79-4.91 mm) medial and 6.01 ± 2.09 mm (range 2.49-9.51 mm) anterior to the DPIN, with no significant difference between sides. All potential angle errors were below 2°. CONCLUSION: The results of this study show that the DPIN can serve as a reference for surgeons using an IM guide system in TKA.
