Article Abstract
Purpose: New research shows the benefits of mobile health (mHealth) interventions for older adults. However, older adults adopt digital technology less than younger ones. This study measures the task effectiveness, perceived usability, and acceptability of a mHealth intervention (i.e., +) consisting of a wearable activity tracker, access to the app, and personalized text messages to promote healthy behaviors in older adults.
Methods: Participants used the + intervention for 12 weeks and engaged in monthly clinic visits with an advanced practice nurse (APRN) to monitor their progress. The monthly sessions instructed them to use the think-aloud process while doing specific tasks (e.g., using the app). Participants also completed the USABILITY Survey and provided feedback on the intervention's acceptability after the 12-week trial.
Results: Thirty older adults (mean age 66.6 ± 5.9 years, 60% female, 60% married, 50% Asian, 37% White, and 13% Hispanic) participated in this sub-analysis. Participants were able to complete the assigned tasks efficiently. The usability satisfaction assessment suggests a high level of satisfaction. The participants responded positively to + and successfully incorporated it into their routines.
Conclusions: Our findings show that + technologies, including smartphones, smartphone-based applications, and integrated sensors, are practical, usable, and acceptable for older adults at risk for cardiovascular disease. These scalable, low-cost technologies offer methods to monitor and promote a healthy lifestyle and enhance overall well-being.

Background: Children in low- and middle-income countries face obstacles to optimal language and cognitive development due to a variety of factors related to adverse socioeconomic conditions. One of these factors is compromised caregiver-child interactions and associated pressures on parenting. Early development interventions, such as dialogic book-sharing (DBS), address this variable, with evidence from both high-income countries and urban areas of low- and middle-income countries showing that such interventions enhance caregiver-child interaction and the associated benefits for child cognitive and socioemotional development.

Background: With the availability of more advanced and effective treatments, life expectancy has improved among patients with metastatic breast cancer (MBC), but this makes communication with their medical oncologist more complex. Some patients struggle to learn about their therapeutic options and to understand and articulate their preferences. Mobile health (mHealth) apps can enhance patient-provider communication, playing a crucial role in the diagnosis, treatment, quality of life, and outcomes for patients living with MBC.

Objectives: Long-term worker shortages in Australian residential aged care are well-documented. These shortages adversely impact residents' well-being and the morale of staff caring for them. This study aimed to explore staff and management experiences through workplace theories related to worker satisfaction: job demands-resources theory, self-determination theory, moral disengagement and work as calling theory, at NewDirection Care, which provides innovative aged care in Queensland.

Importance: Recent longitudinal studies in patients with unruptured intracranial aneurysms (UIAs) suggested that aneurysm wall enhancement (AWE) on magnetic resonance imaging (MRI) predicts growth and rupture. However, because these studies were limited by small sample size and short follow-up duration, it remains unclear whether this radiological biomarker has predictive value for UIA instability.
Objective: To determine the 4-year risk of instability of UIAs with AWE and investigate whether AWE is an independent predictor of UIA instability.
