Smartphone App to Detect Pathological Myopia Using Spatial Attention and Squeeze‐Excitation Network as a Classifier and Segmentation Encoder

ABSTRACTPathological myopia (PM) is a worldwide visual health concern that can cause irreversible vision impairment. It affects up to 20 crore population, causing social and economic burdens. Initial screening of PM using computer‐aided diagnosis (CAD) can prevent loss of time and finances for intricate treatments later on. Current research works utilizes complex models that are too resource‐intensive or lack explanations behind the categorizations. To emphasize the significance of artificial intelligence for the ophthalmic usage and address the limitations of the current studies, we have designed a mobile‐compatible application for smartphone users to detect PM. For this purpose, we have developed a lightweight model, using the enhanced MobileNetV3 architecture integrated with spatial attention (SA) and squeeze‐excitation (SE) modules to effectively capture lesion location and channel features. To demonstrate its robustness, the model is tested against three heterogeneous datasets namely PALM, RFMID, and ODIR reporting the area under curve (AUC) score of 0.9983, 0.95, and 0.94, respectively. In order to support PM categorization and demonstrate its correlation with the associated lesions, we have segmented different forms of PM lesion atrophy, which gave us intersection over union (IOU) scores of 0.96 and fscore of 0.97 using the same SA+SE inclusive MobileNetV3 as an encoder. This lesion segmentation can aid ophthalmologists in further analysis and treatment. The optimized and explainable model version is calibrated to develop the smartphone application, which can identify fundus image as PM or normal vision. This app is appropriate for ophthalmologists seeking second opinions or by rural general practitioners to refer PM cases to specialists.

Development and validation of a web application to collect food supply data associated with their nutritional composition and environmental impacts

Measuring what people eat is a major methodological challenge. We developed and validated a new web-based method to record actual food supply data that would be less time consuming than the original method (i.e., food supply diary). Through the COD-Appro web application, participants can enter their food supplies by selecting a food item from a list based on items included in French food databases; thus automatically associated with nutrient composition and environmental impacts data. We recruited 102 participants who used COD-Appro during one month, among which 30 also used a classical paper-based food supply diary to be able to compare the two methods. A feedback questionnaire was completed by all the participants. The two methods showed no difference between the price and the quantity of food purchases when compared by food groups (n = 10) which confirms that the new method was robust compared to the original method. In addition, participants reported good usability of the COD-Appro web application and its use saved a considerable amount of time to the experimenters by integrating data entry and pairing with food databases (nutrient composition and environmental impacts) into the data collection step performed by the participants themselves.•Web-based food supply data collection•Association with nutrient composition and environmental impacts•External validity compared to original method (i.e., food supply diary)

Promoting vigorous intermittent lifestyle physical activity (vilpa) in middle-aged adults: an evaluation of the movsnax mobile app

BackgroundMost adults fail to meet the moderate to vigorous physical activity-based recommendations needed to maintain or improve health. Vigorous Intermittent Lifestyle Physical Activity (VILPA) refers to short (1–2 min) high-intensity activities that are integrated into activities of daily living. VILPA has shown strong potential to improve health and addresses commonly reported barriers to physical activity. However, it is unknown how VILPA can best be promoted among the adult population. This study aimed to evaluate the usability, user engagement, and satisfaction of a mobile application (MovSnax) designed to promote VILPA.MethodsA concurrent mixed methods design was used. It comprised four parts. Part A was a survey with n = 8 mHealth and physical activity experts who had used the app over 7–10 days. Part B was think-aloud interviews with n = 5 end-users aged 40–65 years old. Part C was a survey with a new group of 40-65-year-old end-users (n = 35) who had used the MovSnax app over 7–10 days. Part D was semi-structured interviews with n = 18 participants who took part in Part C. Directed content analysis was used to analyze the results from Parts A, B, and D, and descriptive statistics were used to analyze findings from Part C.ResultsParticipants reported positive views on the MovSnax app for promoting VILPA but also identified usability issues such as unclear purpose, difficulties in manual data entry, and limited customization options. Across the different data collections, they consistently emphasized the need for more motivational features, clearer feedback, and gamification elements to enhance engagement. Quantitative assessment showed satisfactory scores on objective measures but lower ratings on subjective aspects, possibly due to unfamiliarity with the VILPA concept and/or technical barriers.ConclusionsThe MovSnax app, tested in the present study, is the world’s first digital tool aimed specifically at increasing VILPA. The findings of the present study underscore the need for further app refinement, focusing on clarifying its purpose and instructions, boosting user engagement through personalization and added motivational elements, enhancing accuracy in detecting VILPA bouts, implementing clearer feedback mechanisms, expanding customization choices (such as font size and comparative data), and ensuring transparent and meaningful activity tracking.
