It was recently proposed that both experience-driven and object-based perceptual grouping contribute to holistic face processing. We investigated whether motion-as a common fate perceptual grouping cue-could enhance the holistic processing of misaligned faces. We manipulated alignment and motion (dynamic and static) of study and test faces in a modified complete composite task in which the congruency effect was regarded as an indicator of holistic processing. Participants made same-different judgments about the top halves of two sequentially presented composite faces. We observed that when the study faces were dynamic, regardless of whether the test faces were dynamic or static, misaligned-misaligned face pairs were processed holistically. When the study faces were static, misaligned-misaligned face pairs showed no holistic processing, and neither did inverted faces. These results indicate that motion can promote the holistic processing of misaligned faces. Our findings provide important insights into different types of holistic face processing, and we discuss these types as well as their relationships with each other in depth.

Purpose: This research aims to identify the problems and needs of families of children with reading difficulties, develop an Integrated Process-Based Family Education Program (IPMD-F) to address these needs, and implement it.

Methods: The study used a community-based participatory action research approach, following a four-stage process: general information collection, needs identification and action plan creation, development and implementation of the IPMD-F, and evaluation. Conducted during the 2023-2024 academic year in Ankara, Turkey, with 16 volunteer parents of children diagnosed with learning disabilities, data were collected using qualitative and quantitative tools.

Background: The optimal control of type 2 diabetes (T2D) is defined by the innate mastery of self-management behaviours. This study is designed to condense the lived experiences of people with T2D in relation to factors 'exterior' to themselves into a universal self-management inventory (Assessment of Self-Management Questionnaire in Diabetes Mellitus-External Reality; ASQ-DM-EX).

Methods: We collected responses to an online and physical survey from people living with T2D through a quantitative cross-sectional study.

Background: Although substantial evidence exists regarding the treatment of pressure ulcers, there is a lack of studies demonstrating a comprehensive nursing approach for managing pressure ulcers in the ICU, particularly among patients with invasive mechanical ventilation from developing countries like Honduras. This gap in research is significant as the risk and impact of pressure ulcers on health recovery cannot be disregarded.

Objective: This study aimed to analyze Honduran nursing care for pressure ulcers in patients with invasive mechanical ventilation admitted to Intensive Care Units.

Investigating the role of intratumoral Streptococcus mitis in gastric cancer progression: insights into tumor microenvironment.

Growing evidence implicates that intratumoral microbiota are closely linked to cancer progression; however, research on the role of these microbiota in the development of gastric cancer remains limited. Here, using 16 S rRNA sequencing, tumor tissue proteomics and serum cytokines analysis, we identified enrichment of specific microbial communities within tumors of gastric cancer patients, possibly affecting the tumor microenvironment by immune modulation, metabolic processes, and inflammatory responses. Based on the results of in vivo experiments and intratumoral microbiota analysis, we found that Streptococcus mitis can inhibit gastric cancer progression via suppressing M2 macrophage polarization and infiltration, as well as altering the intratumoral microbial community.

Contrastive learning with transformer for adverse endpoint prediction in patients on DAPT post-coronary stent implantation.

Front Cardiovasc Med

January 2025

Department of Artificial Intelligence and Informatics, Mayo Clinic, Jacksonville, FL, United States.

Background: Effective management of dual antiplatelet therapy (DAPT) following drug-eluting stent (DES) implantation is crucial for preventing adverse events. Traditional prognostic tools, such as rule-based methods or Cox regression, despite their widespread use and ease, tend to yield moderate predictive accuracy within predetermined timeframes. This study introduces a new contrastive learning-based approach to enhance prediction efficacy over multiple time intervals.
