Introduction: Resilience is an important but often neglected aspect of healthy or successful aging. This study used a new approach for modelling psychosocial resilience to investigate responses when faced with age-typical losses. Rather than viewing resilience as a trait, we modelled trajectories of life satisfaction when faced with partner or functional loss in later life to identify resilient trajectories.

In a randomized phase 2b trial (NCT03703102) for adult patients with moderate-to-severe atopic dermatitis (AD), treatment with the T cell rebalancing anti-OX40 receptor antibody rocatinlimab (AMG 451/KHK4083) led to significant improvements in clinical measurements versus placebo including whole-body Eczema Area and Severity Index (EASI) score. AD manifestations can impact variable anatomic regions, and involvement of the head and neck, a sensitive, hard-to-treat area, can negatively impact quality of life. In this post hoc analysis, we investigated response to rocatinlimab treatment across anatomic regions, including the head and neck.

Background: Physical activity is essential for youth physical and mental health, yet just 15% of adolescent girls versus 22% of adolescent boys worldwide meet the World Health Organization guideline of 60 minutes of moderate-to-vigorous physical activity per day. As activity patterns established in adolescence often persist into adulthood, there is a looming risk of adverse health outcomes due to insufficient physical activity. A persistent challenge faced by physical activity providers, however, is recruiting adolescent girls into their programmes.

A Structural and Functional Mimic of P680.

Angew Chem Int Ed Engl

October 2024

School of Chemistry, Trinity College Dublin, The University of Dublin, College Green, Dublin, Dupin 2, Ireland.

One or multiple chlorophyll a molecules are employed in the reaction center of photosystem II's main electron donor (defined as P680). We have a poor understanding of how the reaction center facilitates water oxidation in photosystem II and the roles that mono- and/or multimeric chlorophyll groups play when P680 oxidizes a neighboring tyrosine in order to drive water oxidation at the oxygen evolving complex. We have prepared a dimeric Mg-porphyrin complex [Mg(BTPP)] (1, H-BTPP=1,2-bis-(10,15,20-triphenylporphyrin-5-yl)-benzene) as a structural and functional mimic of the dimeric core of P680.

Psilocybin-assisted neurofeedback for the improvement of executive functions: a randomized semi-naturalistic-lab feasibility study.

Philos Trans R Soc Lond B Biol Sci

December 2024

Department of Clinical and Developmental Neuropsychology, University of Groningen, Groningen, Netherlands.

Executive function deficits, common in psychiatric disorders, hinder daily activities and may be linked to diminished neural plasticity, affecting treatment and training responsiveness. In this pioneering study, we evaluated the feasibility and preliminary efficacy of psilocybin-assisted frontal-midline theta neurofeedback (NF), a neuromodulation technique leveraging neuroplasticity, to improve executive functions (EFs). Thirty-seven eligible participants were randomized into an experimental group ( = 18) and a passive control group ( = 19).

Article Synopsis
  • Stressor-response models help track changes in ecosystems caused by human activities and natural factors, but often overlook nonlinearity and stressor interactions.
  • An analysis of data from 177 Irish river sites revealed that incorporating nonlinearity improves five out of six biological response models, and all models benefitted from considering interactions between stressors.
  • The study highlights that the relationship between stressors and their ecological impact can depend on other environmental factors, suggesting that more complex modeling techniques are necessary for effective ecosystem management.

Distinct Longitudinal Changes in EEG Measures Reflecting Functional Network Disruption in ALS Cognitive Phenotypes.

Brain Topogr

October 2024

Academic Unit of Neurology, School of Medicine, Trinity Biomedical Sciences Institute, Trinity College Dublin, University of Dublin, Room 5.43, 152-160 Pearse Street, Dublin 2, D02 R590, Ireland.

Amyotrophic lateral sclerosis (ALS) is characterised primarily by motor system degeneration, with clinical evidence of cognitive and behavioural change in up to 50% of cases. We have shown previously that resting-state EEG captures dysfunction in motor and cognitive networks in ALS. However, the longitudinal development of these dysfunctional patterns, especially in networks linked with cognitive-behavioural functions, remains unclear.

Article Synopsis
  • Structural income inequality, defined as the uneven distribution of income across regions, affects brain dynamics and functions more significantly than individual factors like age or education.
  • This study used EEG signals from 1,394 healthy participants across 10 countries to explore how structural inequality predicts various brain activity metrics, revealing a connection between socioeconomic conditions and neural functioning.
  • Results show that higher structural income inequality is associated with lower brain signal complexity, increased random neural activity, and reduced power in certain brain wave frequencies, suggesting the need for a broader understanding of how social factors influence brain health.

Background: Scientific publications have been growing exponentially, contributing to an oversaturated information environment. Quantifying a research output's impact and reach cannot be solely measured by traditional metrics like citation counts as these have a lag time and are largely focused on an academic audience. There is increasing recognition to consider 'alternative metrics' or altmetrics to measure more immediate and broader impacts of research.
