AI Article Synopsis
- Mobile device-assisted dietary ecological momentary assessments (EMAs) evaluate real-time dietary intake, minimizing recall bias and participant burden while enhancing ecological validity.
- The developed EMAs assess adherence to the Mediterranean diet by randomly sending multiple-choice questions regarding the consumption of key food groups over the past 24-48 hours.
- A scoring system calculates adherence percentages and diet quality weekly, with personalized reports sent to participants to highlight dietary strengths and weaknesses and promote healthier choices.
Article Abstract
Mobile device-assisted dietary ecological momentary assessments (EMAs) have emerged as a new tool allowing the evaluation of dietary intake in real time, in a real-world setting and in a continuous manner. They have the potential to minimize recall bias, participant, and investigator burden, and decrease economic and time investment while maximizing ecological validity. We developed a set of EMAs aimed at evaluating continuous adherence to the MedDiet. Four multiple-choice EMAs are sent daily in a randomized manner from a total of eight questions. The EMAs enquire about the consumption of 11 key food groups of the Mediterranean diet in the last 24-48 h in a semi-quantitative way. EMAs capture the daily frequency of consumption of fruits, vegetables, and extra virgin olive oil on different days of the week. Additionally, EMAs capture the weekly frequency of consumption of whole grain products, sugary drinks, nuts, legumes, sweets, fish and seafood, and red and processed meats. A designed scoring system behind the EMAs extracts the percentage of adherence to the MedDiet recommendations and calculates a quality index of the diet every week. Individualized reports are sent periodically to the volunteers highlighting the strengths and weaknesses of their diet. EMAs are also expected to have a behavioral effect, reinforcing the choice of Mediterranean foods.

Article Synopsis
- Sarcopenia and osteoarthritis are age-related diseases that make each other worse, but exercise can help improve these conditions.
- The study looks at using mobile technology, like ChatGPT-4 and wearable devices, to create a personalized exercise program for patients with these diseases.
- 278 patients will be divided into two groups: one will use mobile rehab services with ChatGPT-4, and the other will get traditional therapies, to see which is more effective over three months.

Delay-sensitive task offloading in a device-to-device assisted mobile edge computing (D2D-MEC) system with energy harvesting devices is a critical challenge due to the dynamic load level at edge nodes and the variability in harvested energy. In this paper, we propose a joint dynamic task offloading and CPU frequency control scheme for delay-sensitive tasks in a D2D-MEC system, taking into account the intricacies of multi-slot tasks, characterized by diverse processing speeds and data transmission rates. Our methodology involves meticulous modeling of task arrival and service processes using queuing systems, coupled with the strategic utilization of D2D communication to alleviate edge server load and prevent network congestion effectively.
