AI Article Synopsis
- The study aimed to explore how peripheral neuropathy and cognitive function impact gait performance in older adults with type 2 diabetes.
- Older adults with diabetes walked slower and had less stable gait patterns compared to healthy controls, particularly when performing tasks that required dual attention.
- Cognitive impairment further worsened these gait issues, with those experiencing cognitive difficulties exhibiting slower walking speeds and increased variability in their walking patterns, regardless of whether they had neuropathy.
Article Abstract
Objective: To investigate the effect of peripheral neuropathy and cognition on gait performance in older adults with type 2 diabetes mellitus.
Design: Cross-sectional study.
Setting: Community and residential aged care setting.
Participants: Older adults (N=101; 56 patients with diabetes, 28 with peripheral neuropathy and 28 without peripheral neuropathy; and 45 matched controls).
Interventions: Not applicable.
Main Outcome Measures: Spatiotemporal gait parameters were recorded under 3 conditions: simple, counting backward by 3 from 40, and reciting animal names. The Mini-Mental State Examination and the clock drawing test were used to estimate cognitive impairment levels.
Results: Compared with controls, older adults with diabetes walked slower, took shorter strides during all walking conditions, and showed more gait variability especially during dual-task conditions. Gait patterns did not differ between participants suffering from diabetes mellitus with and without neuropathy. Compared with normal walking, dual-task conditions affected all gait parameters similarly in all groups. Backward counting affected gait more than animal naming in participants with diabetes but not in healthy controls. Additional analyses in older adults with diabetes showed that participants with impaired cognitive function walked slower, took shorter strides, had shorter double support time, and increased gait variability compared with participants with intact cognitive function.
Conclusions: This study showed that gait parameters are affected in older adults with type 2 diabetes. Gait was further affected by reduced cognitive function, irrespective of the presence of neuropathy.

School of Nursing, The Hong Kong Polytechnic University, Hong Kong, China.
Background: Previous research suggested that parent-administered pediatric tuina could improve symptoms of attention-deficit/hyperactivity disorder (ADHD), such as sleep quality and appetite.
Objective: This study aimed to explore the experiences and perceptions of parents administering pediatric tuina to school-aged children with ADHD in Hong Kong.
Methods: This qualitative study was embedded in a pilot randomized controlled trial on parent-administered pediatric tuina for improving sleep and appetite in school-aged children diagnosed with ADHD.
Increasing Access to Mental Health Supports for 18- to 25-Year-Old Indigenous Youth With the JoyPop Mobile Mental Health App: Study Protocol for a Randomized Controlled Trial.
JMIR Res Protoc

Department of Psychology, Lakehead University, Thunder Bay, ON, Canada.
Background: Transitional-aged youth have a high burden of mental health difficulties in Canada, with Indigenous youth, in particular, experiencing additional circumstances that challenge their well-being. Mobile health (mHealth) approaches hold promise for supporting individuals in areas with less access to services such as Northern Ontario.
Objective: The primary objective of this study is to evaluate the effectiveness of the JoyPop app in increasing emotion regulation skills for Indigenous transitional-aged youth (aged 18-25 years) on a waitlist for mental health services when compared with usual practice (UP).
Self-Guided Smartphone App (Vimbo) for the Reduction of Symptoms of Depression and Anxiety in South African Adults: Pilot Quantitative Single-Arm Study.

Private Practice, Ballito, South Africa.
Background: Barriers to mental health assessment and intervention have been well documented within South Africa, in both urban and rural settings. Internationally, evidence has emerged for the effectiveness of technology and, specifically, app-based mental health tools and interventions to help overcome some of these barriers. However, research on digital interventions specific to the South African context and mental health is limited.

Background: Few studies have explored the relationship between macronutrient intake and sleep outcomes using daily data from mobile apps.
Objective: This cross-sectional study aimed to examine the associations between macronutrients, dietary components, and sleep parameters, considering their interdependencies.
Methods: We analyzed data from 4825 users of the Pokémon Sleep and Asken smartphone apps, each used for at least 7 days to record objective sleep parameters and dietary components, respectively.
Co-Designing a Digital Brief Intervention to Reduce the Risk of Prescription Opioid-Related Harm Among People With Chronic Noncancer Pain: Qualitative Analysis of Patient Lived Experiences.

January 2025
Faculty of Medicine, The University of Queensland, Brisbane, Australia.
Background: Opioid medications are important for pain management, but many patients progress to unsafe medication use. With few personalized and accessible behavioral treatment options to reduce potential opioid-related harm, new and innovative patient-centered approaches are urgently needed to fill this gap.
Objective: This study involved the first phase of co-designing a digital brief intervention to reduce the risk of opioid-related harm by investigating the lived experience of chronic noncancer pain (CNCP) in treatment-seeking patients, with a particular focus on opioid therapy experiences.
