AI Article Synopsis
Article Abstract
Introduction: Freely accessible online tests for the diagnosis of Alzheimer's disease (AD) are widely available. The objective of this study was to evaluate these tests along three dimensions as follows: (1) scientific validity; (2) human-computer interaction (HCI) features; and (3) ethics features.
Methods: A sample of 16 online tests was identified through a keyword search. A rating grid for the tests was developed, and all tests were evaluated by two expert panels.
Results: Expert analysis revealed that (1) the validity of freely accessible online tests for AD is insufficient to provide useful diagnostic information; (2) HCI features of the tests are adequate for target users, and (3) the tests do not adhere to accepted ethical norms for medical interventions.
Discussion: The most urgent concerns raised center on the ethics of collecting and evaluating responses from users. Physicians and other professionals will benefit from a heightened awareness of these tools and their limitations today.

Obesity Incidence According to Branched-Chain Amino Acid Intake and Plant-Based Diet Index Among Brazilian Adults: A Six-Year Follow-Up of the CUME Study.
Nutrients
January 2025
Laboratory of Energy Metabolism and Body Composition, Department of Nutrition and Health, Federal University of Viçosa, Viçosa 36570-900, Brazil.
Background: Few studies have evaluated the impact of branched-chain amino acid (BCAA) intake on the risk of obesity in adults. The results are contradictory, and the causality has not been explored. This study assessed the association between BCAA intake and obesity incidence among Brazilian adults and investigated the potential moderating role of the plant-based index (PDI) in this relationship.

Background/objectives: Eating disorders (EDs) result from complex interactions of biological, psychological, social, and cultural factors, disproportionately affecting adolescents and young adults. Social media, peer pressure, and self-esteem issues contribute to ED prevalence. This study examines ED risk, eating behaviors, and self-esteem among individuals aged 16-25, exploring differences by gender, age, and social media usage.

Sensors (Basel)
January 2025
Centre of Mechanical Technology and Automation (TEMA), Department of Mechanical Engineering, University of Aveiro, 3810-193 Aveiro, Portugal.
To automate the quality control of painted surfaces of heating devices, an automatic defect detection and classification system was developed by combining deflectometry and bright light-based illumination on the image acquisition, deep learning models for the classification of non-defective (OK) and defective (NOK) surfaces that fused dual-modal information at the decision level, and an online network for information dispatching and visualization. Three decision-making algorithms were tested for implementation: a new model built and trained from scratch and transfer learning of pre-trained networks (ResNet-50 and Inception V3). The results revealed that the two illumination modes employed widened the type of defects that could be identified with this system, while maintaining its lower computational complexity by performing multi-modal fusion at the decision level.

Increasing evidence indicates that skin disorders may contribute to an increased risk of autism spectrum disorder (ASD). They can affect the quality of life, and they have an impact on social isolation, behavioral problems, cognitive scores, and some subscales of ASD. This study was an online questionnaire-based, observational, and cross-sectional study conducted during the period from August 2022 through January 2023 to examine dermatological manifestations among ASD individuals compared to controls.

Neurofibromatosis is a genetic disorder arising de novo or with an autosomal dominant transmission that typically presents either at birth or in early childhood, manifesting through distinctive clinical features such as multiple café-au-lait spots, benign tumors in the skin, bone enlargement, and deformities. This literature review aims to resume the spectrum of maternal and fetal complications encountered in pregnant women with neurofibromatosis type 1 (NF1). Thorough research was conducted on databases such as Web of Science, PubMed, Science Direct, Google Scholar, and Wiley Online Library.
