When The Therapist Is An Algorithm: Understanding Autism Spectrum Students’ Acceptance Of Generative Ai As A Mental Well-Being Tool Through The Technological Acceptance Model, Jossy P. George, Peter Muttungal, Benny Jeyekumar Davidson, Nishi Priya

Northeast Journal of Complex Systems (NEJCS)

This study examines the psychological and technological factors of the acceptance and emotional well-being of 349 college students with autism who use generative artificial intelligence tools as sources of psychological and emotional support. Grounded on the model of Technology Acceptance Model (TAM), the research studies relationships among perceived empathy, perceived usefulness, ease of use, emotional trust, continuance intention, and overall well-being. Structural equation modelling found that the perceived empathy was a significant predictor of ease of use and usefulness, while emotional trust and continuance intention proved to be significant predictors of emotional well-being. To reinforce these results, predictive modelling performed …

Self-Esteem Development And Emotional And Behavioral Disorders, Bahaa Al Ghraibeh

Archives of Assessment Psychology

Self-esteem is a fundamental psychological construct that develops across the lifespan and influences academic, social, emotional, and behavioral functioning. Research consistently links healthy self-esteem with positive developmental outcomes, including improved educational achievement, stronger interpersonal relationships, and better mental health. At the same time, emotional and behavioral disorders (EBD) are associated with persistent emotional, behavioral, academic, and social difficulties that can interfere with healthy self-development. This paper reviews the developmental trajectory of self-esteem from early childhood through adulthood and examines how the experiences commonly associated with EBD may negatively affect that trajectory. The review discusses how children begin forming self-esteem at …

Community-Based Education For Hypertension Management Through Lifestyle Modifications – An Evidence-Based Practice Project, Elizabeth Mkroyan

Loma Linda University Electronic Theses, Dissertations & Projects

Hypertension is a highly prevalent chronic disease and a leading contributor to numerous life-threatening complications, including cardiovascular disease and stroke. Time constraints during routine clinical encounters often limit providers' ability to deliver comprehensive education on nonpharmacologic strategies. Community-based educational programs can help close this gap by teaching people about changes they can make to their lives in safe places like a Church. This evidence-based practice project aims to evaluate whether community-based education on lifestyle modifications can improve self-efficacy, self-care practices and behaviors and have high rates of participant satisfaction with the intervention.

Metastatic cancer cell fate is shaped by the local microenvironment niches. To unbiasedly define the cellular and molecular features of metastatic niches, we developed sortase A-based microenvironment niche tagging (SAMENT), which selectively labels cells encountered by cancer cells during metastasis. Applying SAMENT across multiple cancer models and target organs revealed shared niche features, including macrophage enrichment and T cell depletion, alongside marked organ-specific phenotype heterogeneity in niche macrophages. In bone, metastatic niches are enriched for macrophages expressing estrogen receptor alpha (ERα) with active ERα signaling. Conditional deletion of Esr1 in macrophages significantly impaired bone colonization by enabling T cell infiltration. …

In Silico Prediction Of Cd8+ T-Cell Multi-Epitopes And Hla Distribution Analysis For Muc13: An Onco-Vaccine Design Strategy, Abigail Gomez, John Mills, Aidan Mata, Anupam Dhasmana, Swati Dhasmana, Sheema Khan, Murali Yallapu, Subhash Chauhan

Research Symposium

Background: Mucin 13 (MUC13), a transmembrane glycoprotein, plays a crucial role in the progression of epithelial cancers, particularly liver and pancreatic cancers. It is frequently overexpressed in malignant cells, disrupting cellular adhesion and facilitating invasive behavior. The extracellular domain and phosphorylation potential in its cytoplasmic region connect MUC13 to oncogenic signaling pathways, making it a valuable target for immunotherapy. However, challenges such as the immunosuppressive tumor microenvironment remain significant obstacles, and addressing these issues in the lab is challenging without computational intervention. To address this, we have employed an in-silico approach to design CD8+ T-cell multi-epitopes targeting MUC13 HLA class …

Richmond Agitation-Sedation Scoring Implementation In A Critical Access Hospital, Jasmine A. Hobbs

Doctor of Nursing Practice Scholarly Projects

Mechanically ventilated patients who are boarding in rural emergency departments face an increased risk of inconsistent sedation management due to the lack of standardized protocols and the extended transfer times to higher levels of care. The variability in sedation practices can lead to both under- and over-sedation, which negatively affects patient comfort, safety, and clinical outcomes. Research suggests that sedation protocols incorporating the Richmond Agitation-Sedation Scale (RASS) can shorten mechanical ventilation duration and improve clinical outcomes. The purpose of this project was to evaluate the effectiveness of a targeted educational intervention on improving nursing knowledge and comfort with the RASS …

Evidence From A Single Tertiary-Care Pediatric Hospital In Italy, Manuele Cesare, Gianfranco Damiani, Gloria Anderson, Jessica Preziosi, Rosemary Frasso, Leonardo Villani, Nursing And Public Health Group, Vittorio Maio, Antonello Cocchieri

College of Population Health Faculty Papers

BACKGROUND/OBJECTIVES: Rural-urban disparities are well documented in pediatric healthcare, influencing access, service organization, and outcomes. However, whether these differences extend to the domain of nursing care remains unclear. This study examined the association between degree of urbanization and nursing complexity among children admitted to a single tertiary-care pediatric hospital, comparing clinical, organizational, and nursing characteristics across geographic groups.

METHODS: Routinely collected electronic nursing documentation and hospital administrative records were retrospectively examined in a tertiary-care pediatric hospital in Rome, Italy. Children aged 2 to < 18 years were consecutively included. Degree of urbanization was defined using the ISTAT-derived DEGURBA classification. The study outcome for nursing complexity corresponded to the number of nursing diagnoses documented at hospital admission. Descriptive analyses and a multivariable negative binomial regression model assessed the association between urbanization and nursing complexity, adjusting for age, sex, DRG weight, number of medical diagnoses, and chronic conditions.

RESULTS: Among 1652 pediatric hospitalizations, those from rural areas showed a higher clinical burden, with significantly higher …

Increased Neural Activity In The Bed Nucleus Of The Stria Terminalis Of Uninfected Canaries After Observation Of Infected Conspecifics, Madeleine Chang, Sophia Santangelo, Devon Comito, Bennett Hardy, Patricia C. Lopes

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Recent evidence suggests that the immune system may be upregulated in anticipation of pathogen exposure, yet the neural mechanisms that respond to and signal impending infection risk remain poorly understood. We investigated neural responses to infection risk in uninfected hosts observing infected conspecifics, using the canary (Serinus canaria domestica)—Mycoplasma gallisepticum host–parasite system. We focused on five brain regions of interest, comprising three nodes of the social decision-making network—preoptic area, bed nucleus of the stria terminalis (BNST) and hippocampus—a stress modulatory region (paraventricular nucleus) and a visual processing region (nucleus rotundus). After 1 h of observing infected canaries, …

Mitochondria-Er Contact Sites (Mercs) In The Cell Cycle: Molecular Architecture And Functional Remodeling Across Cellular States, Eduardo Silva-Pavez, Bruno Torres-Gonzalez, Michelle Sotomayor, Benjamín Cartes-Saavedra, Dorian V. Ziegler, Yessia Hidalgo-Fadic, Ulises Ahumada-Castro

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Mitochondria–endoplasmic reticulum (ER) contact sites (MERCS) are nanoscopic, dynamic platforms integrating metabolism, signaling, and stress responses to regulate cell fate. These nanoscopic interfaces remodel continuously to meet the demands of proliferating, quiescent, and senescent cells. We synthesize evidence that MERCS actively coordinate local Ca2+ signaling, non-vesicular lipid transfer, and proteostasis to shape mitochondrial function and cellular homeostasis. We discuss how MERCS architecture changes across the cell cycle and during arrest, distinguishing adaptive from maladaptive remodeling, and consider therapeutic potential in aging and age-related disease.
