ABSTRACT Diabetic wounds are hard-healing chronic
wounds, mainly caused by wound infection, excessive inflammation, diabetic neuropathy, and peripheral vascular disease. Hence, comprehensive improvement of diabetic wound healing is of great significance in clinical practice. However, the current research on diabetic wounds mainly focuses on wound infection and angiogenesis, lacking the exploration of neuroregeneration and immunomodulation. In this study, we develop a multifunctional conductive hydrogel (PACPH) based on polydopamine-modified silver nanoparticles (AgNPs@PDA), cellulose nanocrystals (CNC)/polypyrrole (PPy) composites, and polyvinyl alcohol as an efficient wound dressing. The PACPH scaffold features multiple functions, including desirable mechanical properties, tissue adhesion, conductivity, and broad-spectrum antibacterial activity. Inspired by the endogenous electric field, the strategy of combining hydrogel with electrical stimulation (ES) is also proposed to accelerate the healing of diabetic wounds. Notably, the participation of ES can effectively promote nerve repair, realize the polarization of macrophages toward the M2 phenotype, and rapid angiogenesis, comprehensively improving the healing of diabetic wounds. This advanced collaborative strategy opens a new avenue in treating diabetic wound.

Abstract
Background While the use of self-management apps has considerable promise to efficiently reduce the diabetes burden that disproportionally affects low- and middle-income countries (LMICs), and the multisectoral and multidisciplinary approaches have been encouraged to be used in diabetes management, little is known about the status of the integration of these approaches in the existing diabetes self-management apps. This review examines the diabetes apps in China as an indication of the current status of integrating multisectoral and multidisciplinary approaches in diabetes mHealth care in LMICs.
Methods Eligible diabetes apps were searched on major Chinese app stores up to December 23, 2022. The app comprehensiveness index (ranging 0–80) regarding the app functions and diabetes management domains was created. The multisectoral and multidisciplinary features were summarized using indices derived from current guidance.
Results Sixty-six apps were reviewed, all developed by private companies. The average comprehensiveness score was 16, with many major self-management domains and functions not represented among the reviewed apps. Forty apps (61%) involved multiple sectoral entities, with public/private and private/private collaborations being the most common collaborative combinations. Thirty-seven apps (56%) involved multiple disciplines, among which endocrinology/metabolism, nutrition, and cardiovascular medicine were the top three most common disciplines. Compared to non-multidisciplinary apps, multidisciplinary apps tended to provide more comprehensive services in apps (6.14 vs. 5.18, p=0.0345). Different sectors and disciplines tended to work independently, without robust interactions, in providing diabetes management services in the reviewed apps.
Conclusion Multisectoral and multidisciplinary features has presented in the current diabetes self-management apps in China; however, it is still in its infancy and significant limitations existed. More engagement of civil society organizations and community groups and innovative collaborations between sectors and disciplines are needed to provide comprehensive, continuous, and patient-centered mHealth care for patients with diabetes in LMICs like China. Clear guidance for integrating and evaluating the multisectoral and multidisciplinary efforts in self-management apps
is necessary to ensure the effective use of mHealth solutions for diabetes management in LMICs.

Abstract
Aims/hypothesis We sought to quantify the relationship between morning, afternoon or evening physical activity and consistency (e.g. routine) and risk of type 2 diabetes.
Methods A cohort of 93,095 UK Biobank participants (mean age 62 years) without a history of type 2 diabetes wore a wrist-worn accelerometer for 1 week. We converted accelerometer information to estimate metabolic equivalent of task (MET), summing MET h of total physical activity completed within three intra-day time segments (morning, afternoon and evening). We quantified physical activity consistency as the SD of participants’ daily total physical activity. We ultimately associated each of the following with incident type 2 diabetes: (1) morning, afternoon or evening ‘time-segmented’ MET h per week; and (2) consistency. We also considered moderate-to-vigorous physical activity (MVPA) and vigorous physical activity (VPA) in association with type 2 diabetes incidence.
Results When considering MET as the physical activity measure, we observed protective associations of morning (HR 0.90 [95% CI 0.86, 0.93], p=7×10−8) and afternoon (HR 0.91 [95% CI 0.87, 0.95], p=1×10−5) but did not have evidence for evening physical activity (HR 0.95 [95% CI 0.90, 1.00], p=0.07) with type 2 diabetes. There was no difference between MET-measured morning and afternoon physical activity. Our substitution model highlighted the importance of adjusting for lifestyle factors (e.g. sleep time and diet); the effect of a substitution between afternoon and evening physical activity was attenuated after adjustment for lifestyle variables. Consistency of MET-measured physical activity was not associated with type 2 diabetes (p=0.07). MVPA and VPA were associated with decreased risk for type 2 diabetes at all times of the day.
Conclusions/interpretation Total metabolic equivalents of physical activity in the morning and afternoon had a protective effect on diabetes risk and evening activity was not associated with diabetes. Consistency of physical activity did not play
a role in decreasing risk for diabetes. Vigorous activity is associated with lower risk no matter the time of day of activity.
