Humans and many animals have the ability to assess the confidence of their decisions. However, little is known about the underlying neural substrate and mechanism. In this study we propose a computational model consisting of a group of 'confidence neurons' with adaptation, which are able to assess the confidence of decisions by detecting the slope of ramping activities of decision neurons. The simulated activities of 'confidence neurons' in our simple model capture the typical features of confidence observed in humans and animals experiments. Our results indicate that confidence could be online formed along with the decision formation, and the adaptation properties could be used to monitor the formation of confidence during the decision making.

Evaluation of an Interdisciplinary Educational Program to Foster Learning Health Systems: Education Evaluation.

January 2025
Centre for Digital Transformation of Health, University of Melbourne, Carlton, Australia.
Background: Learning health systems (LHS) have the potential to use health data in real time through rapid and continuous cycles of data interrogation, implementing insights to practice, feedback, and practice change. However, there is a lack of an appropriately skilled interprofessional informatics workforce that can leverage knowledge to design innovative solutions. Therefore, there is a need to develop tailored professional development training in digital health, to foster skilled interprofessional learning communities in the health care workforce in Australia.

This study investigates whether an Image-Guided Radiation Therapy (IGRT) workbook and Cone Beam Computed Tomography (CBCT) case studies enhances Radiation Therapists' (RTTs) confidence analysing Proton Beam Therapy (PBT) CBCTs. An 11-participant questionnaire-based study was conducted to assess pre- and post-training confidence. Prior to training, RTTs exhibited higher confidence in photon CBCT decision-making over proton CBCT, highlighting the need for PBT-specific IGRT training, irrespective of prior photon experience.

Background: Traumatic brain injury (TBI) is a significant public health issue worldwide that affects millions of people every year. Cognitive impairment is one of the most common long-term consequences of TBI, seriously affect the quality of life. We aimed to develop and validate a predictive model for cognitive impairment in TBI patients, with the goal of early identification and support for those at risk of developing cognitive impairment at the time of hospital admission.

Background: An accurate diagnosis of septic versus reactive or autoimmune arthritis remains clinically challenging. A multi-omics strategy comprising metagenomic and proteomic technologies were undertaken for children diagnosed with presumed septic arthritis to advance clinical diagnoses and care for affected individuals.
Methods: Twelve children with suspected septic arthritis were prospectively enrolled to compare standard of care tests with a rapid multi-omics approach.
Assessing the effect of On-site supportive communication training (On-site SCT) on doctor burnout: a randomized controlled trial.

Department of Oncology, Vejle Hospital, University Hospital of Southern Denmark, Vejle, Denmark.
Background: Burnout is a critical factor that can influence the quality of care that doctors provide to their patients. Previous research suggests a link between inadequate communication skills training and burnout, and various approaches to enhance communication skills have been explored as a means to address this issue. However, evidence of the effect of these approaches is lacking.
