We present the case of a young woman admitted for diabetic ketoacidosis with persistent, asymptomatic lactic acid (LA) elevation during the evolving COVID-19 pandemic. Cognitive biases in interpreting an elevated LA in this patient's care resulted in an extensive infectious workup instead of the low-cost and potentially diagnostic provision of empiric thiamine. We discuss clinical patterns and etiologies of LA elevation and the role of thiamine deficiency. We also address cognitive biases potentially affecting the interpretation of elevated lactate levels and provide guidance for clinicians to determine appropriate patients for empiric thiamine administration.

As technological interfaces are relatively new cultural tools, regular interaction can lead to new psychological phenomena, like the baby duck syndrome, where users favor old interfaces over updates. This syndrome is seen as a cognitive bias in human-computer interaction. Two studies were conducted: Study 1 on an Airbnb app (old vs.

Population Health Sciences, Bristol Medical School, University of Bristol, UK.
Background: Trace amine-associated receptor 1 (TAAR1) agonists offer a new approach, but there is uncertainty regarding their effects, exact mechanism of action and potential role in treating psychosis.
Aims: To evaluate the available evidence on TAAR1 agonists in psychosis, using triangulation of the output of living systematic reviews (LSRs) of animal and human studies, and provide recommendations for future research prioritisation.
Method: This study is part of GALENOS (Global Alliance for Living Evidence on aNxiety, depressiOn and pSychosis).
Feared self and morality in obsessive-compulsive phenomena.
Br J Clin Psychol
December 2024
School of Psychology, The Cairnmillar Institute (CMI), Hawthorn East, Victoria, Australia.

The current study investigated the relationship between morality-related feared self, self-relevance and OC-related cognitions and behaviours such as moral deliberation, threat interpretation bias, discomfort, urge to act and likelihood of acting in OC-relevant situations in a non-clinical sample.
Method: A total of 78 participants (27 female, M = 29.
The Effectiveness of Immersive Virtual Reality-Based Treatment for Mental Disorders: A Systematic Review With Meta-Analysis.
Acta Psychiatr Scand
December 2024
VIRTU Research Group, Mental Health Center Copenhagen, Copenhagen University Hospital - Mental Health Services, CPH, Denmark.
Background: The increasing number of studies of immersive virtual reality (VR) interventions for mental disorders call for an examination of the current level of evidence on their effectiveness. The findings may guide scalability and contribute to the advancement and optimization of immersive VR-based interventions for mental disorders.
Methods: A systematic literature search across four databases screened 2443 studies.

Dementia is a health priority for Indigenous peoples. Here, we reviewed studies on the prevalence of dementia or cognitive impairment among Indigenous populations from countries with a very high Human Development Index (≥0·8). Quality was assessed using the Joanna Briggs Institute risk-of-bias tool and CONSolIDated critERia for strengthening the reporting of health research involving Indigenous peoples (CONSIDER), with oversight provided by an Indigenous Advisory Board.
