Aim: To examine subjective and psychophysiological responses to appetitive cues during an alcohol cue reactivity task, and its relation to alcoholic liver disease and assess whether executive functioning is associated with appropriate regulation of cue-elicited responses in individuals with severe alcohol use disorder (AUD).
Methods: Seventeen treatment-seeking alcoholic liver disease patients and a control group of treatment-seeking severe AUD participants completed neuropsychological executive functioning measures (Stroop task; Trail-making test) and the cue reactivity task, whereby control (water) and alcohol beverage cues were presented, followed by respective recovery periods. Subjective alcohol craving and heart rate variability were recorded across the task.
Results: Overall cue reactivity and consequent recovery after cue offset during the cue reactivity task was observed, and alcoholic liver disease participants demonstrated a reduced overall recovery effect. Better Stroop performance related to greater overall and alcohol-specific cue reactivity within the control AUD group, and alcoholic liver disease participants showed dysfunctional activity regardless of executive functioning performance. No group differences in recovery effects according to executive functioning performance were seen.
Conclusion: Among patients with AUD, having alcoholic liver disease seems to reduce overall regulation of responses to eliciting cues. Executive functioning moderated the magnitude of responses during cue exposures in our AUD sample overall; having alcoholic liver disease did not appear to affect regulation related to executive functioning during recovery.

Principles for embedding learning and adaptation into New Zealand health system functioning: the example of the Viable System Model.

This article makes the case for taking a model-based management approach, specifically using the Viable System Model (VSM), to embed learning and adaptation into the New Zealand health system so it can function as a learning health system. We draw on a case study of a specialist clinical service where the VSM was used to guide semi-structured interviews and workshops with clinicians and managers and to guide analysis of the findings. The VSM analysis revealed a lack of clarity of organisational functioning, and of the systems, processes and integrated IT infrastructure necessary to support the fundamental requirements of a learning health system.

Background: We performed an umbrella review to synthesize evidence on the effects of physical activity (PA) interventions on indicators of physical and psychological health among children and adolescents, including body mass index (BMI), blood pressure (BP), depressive symptoms, and cognitive function.
Methods: PubMed, Embase, Web of Science, and the Cochrane Library were systematically searched from inception through 31 July 2023. We included meta-analyses of randomized controlled trials exploring the effects of PA interventions on BMI, BP, depressive symptoms, or cognitive function in healthy or general children and adolescents.
Acute effects of psilocybin on attention and executive functioning in healthy volunteers: a systematic review and multilevel meta-analysis.

Rationale: Psilocybin shows promise for treating neuropsychiatric disorders. However, insight into its acute effects on cognition is lacking. Given the significant role of executive functions in daily life and treatment efficacy, it is crucial to evaluate how psilocybin influences these cognitive domains.

Cognitive impairment is considered to be one of the key features of Parkinson's disease (PD), ultimately resulting in PD-related dementia in approximately 80% of patients over the course of the disease. Several distinct cognitive syndromes of PD have been suggested, driven by different neurotransmitter deficiencies and thus requiring different treatment regimes. In this study, we aimed to identify characteristic brain covariance patterns that reveal how cholinergic denervation is related to PD and to cognitive impairment, focusing on four domains, including attention, executive functioning, memory, and visuospatial cognition.

Objective: This study aims to observe the effect of enrichment rehabilitation (ER) on cognitive function in post-stroke patients and to clarify its underlying mechanism.
Methods: Forty patients with post-stroke cognitive impairment (PSCI) meeting the inclusion criteria were randomly assigned to two groups: conventional medical rehabilitation (CM group) and ER intervention (ER group). All patients underwent assessments of overall cognitive function, attention function, and executive function within 24 h before the start of training and within 24 h after the 8 weeks of training.
