Aim
To determine whether thyroid hormone levels are associated with a specific clinical phenotype in patients with first-episode psychosis (FEP).

Methods
Ninety-eight inpatients experiencing FEP and with less than 6 weeks of antipsychotic treatment were included in the study and were followed up for one year. Baseline psychiatric evaluation included assessment of prodromal symptoms, positive and negative symptoms, depressive symptoms, stressful life events and cycloid psychosis criteria. Thyroid function (thyroid-stimulating hormone (TSH) and free thyroxin (FT4)) was determined at admission. Partial correlation analysis was conducted to analyse the correlation between levels of TSH/FT4 and symptoms. Logistic regression was performed to explore the association between psychopathological symptoms, 12-month diagnoses and thyroid hormones while adjusting for covariates.

Results
Patients with prodromal symptomatology showed lower baseline FT4 levels (OR = 0.06; p = 0.018). The duration of untreated psychosis (DUP) was inversely associated with FT4 concentrations (r = − 0.243; p = 0.039). FEP patients with sudden onset of psychotic symptoms (criteria B, cycloid psychosis) showed higher FT4 levels at admission (OR = 10.49; p = 0.040). Patients diagnosed with affective psychotic disorders (BD or MDD) at the 12-month follow-up showed higher FT4 levels at admission than patients diagnosed with nonaffective psychosis (schizophrenia, schizoaffective) (OR = 8.57; p = 0.042).

Conclusions
Our study suggests that higher free-thyroxine levels are associated with a specific clinical phenotype of FEP patients (fewer prodromal symptoms, shorter DUP duration and sudden onset of psychosis) and with affective psychosis diagnoses at the 12-month follow-up.
Acousto‐Plasmo‐Magnonics: Coupling Spin Waves with Hybridized Phonon‐Plasmon Waves in a 2D Artificial Magnonic Crystal Deposited on a Plasmonic Material

Published: June 2023

AbstractCoupling between spin waves (SWs) and other waves in nanostructured media has emerged as an important topic of research because of the rich physics and the potential for disruptive technologies. Herein, a new phenomenon is reported in this family involving coupling between SWs and hybridized phonon‐plasmon waves in a 2D periodic array of magnetostrictive nanomagnets deposited on a silicon substrate with an intervening thin film of aluminium that acts as a source of surface plasmons. Hybridized phonon‐plasmon waves naturally form in this composite material when exposed to ultrashort laser pulses and they non‐linearly couple with SWs to produce a new breed of waves – acousto‐plasmo‐spin waves that can exhibit a “frequency comb” spanning more than one octave. This phenomenon, that we call acousto‐plasmo‐magnonics resulting from tripartite coupling of magnons, phonons and plasmons, is studied with time‐resolved magneto‐optical‐Kerr‐effect microscopy. The findings also reveal the presence of parametric amplification in this system; energy is transferred from the hybridized phonon‐plasmon modes to the acousto‐plasmo‐spin wave modes to amplify the latter. This opens a path to design novel active metamaterials with tailored and enhanced response. It may enable high‐efficiency magneto‐mechanical‐plasmonic frequency mixing in the GHz−THz frequency regime and provide a unique avenue to study non‐linear coupling, parametric amplification, and frequency comb physics.
Enhanced Förster Energy Transfer Through Horizontal Orientation of Sensitizer Molecules in Hyperfluorescent Organic Light‐Emitting Diodes

Published: June 2023

AbstractFörster resonance energy transfer (FRET) in sensitized fluorescent (SF) organic light‐emitting diodes (OLEDs) is an important process for suppressing triplet exciton loss during energy transfer toward the fluorescent dopant. Herein, the contribution of the relative orientation between the sensitizer and emitting dopant to the FRET in state‐of‐the‐art SF OLEDs is explained using experimental and theoretical approaches. The enhanced relative orientation factor (κ2) from 0.375 to 1.250 is theoretically demonstrated in the FRET theory depending on the orientation of the sensitizer and emitting dopant. On comparing two SF OLED systems with different sensitizers, the sensitizer with a higher horizontal dipole orientation exhibits a higher FRET rate, resulting in the enhanced κ2. The exciton dynamics under device operation are explored to quantitatively verify the contribution of the enhanced FRET rate to the exciton transfer processes; the triplet consumption rate of the sensitizer improves by 2.2 times, demonstrating an efficient exciton transfer.

AbstractBackgroundConflict is inevitable in the emergency department, and conflict resolution is an essential skill for emergency providers to master. Effective conflict management can optimize patient care and enhance professional satisfaction. To communicate effectively in high‐stress, high‐impact situations, sex‐ and gender‐based differences need to be considered.MethodsNine resident, fellow, junior, and senior faculty members of the Academy for Women in Academic Emergency Medicine collaborated to design a 4‐h workshop. The focus was on professional communication and conflict resolution in emergency medicine (EM), with special attention on how sex and gender can influence these processes.ResultsThe final educational workshop utilized a variety of formats focused on communication and effective conflict resolution including: traditional didactics, facilitated small groups with case‐based learning, expert panel discussion, and an experiential learning session. The consideration of how sex‐ and gender‐associated factors might contribute additional complexity or challenges to conflictual interactions were interwoven into each session to highlight alternative vantage points.ConclusionsEffective conflict resolution is an important skill for success in EM. We developed a workshop that went beyond typical communication‐based programming to consider how sex‐ and gender‐related factors influence communication and conflict resolution.
Bioinformatics pipeline to guide post‐GWAS studies in Alzheimer's: A new catalogue of disease candidate short structural variants
Authors: Lutz Michael W. , Chiba‐Falek Ornit 
Published: May 2023

AbstractBackgroundShort structural variants (SSVs), including insertions/deletions (indels), are common in the human genome and impact disease risk. The role of SSVs in late‐onset Alzheimer's disease (LOAD) has been understudied. In this study, we developed a bioinformatics pipeline of SSVs within LOAD–genome‐wide association study (GWAS) regions to prioritize regulatory SSVs based on the strength of their predicted effect on transcription factor (TF) binding sites.MethodsThe pipeline utilized publicly available functional genomics data sources including candidate cis‐regulatory elements (cCREs) from ENCODE and single‐nucleus (sn)RNA‐seq data from LOAD patient samples.ResultsWe catalogued 1581 SSVs in candidate cCREs in LOAD GWAS regions that disrupted 737 TF sites. That included SSVs that disrupted the binding of RUNX3, SPI1, and SMAD3, within the APOE‐TOMM40, SPI1, and MS4A6A LOAD regions.ConclusionsThe pipeline developed here prioritized non‐coding SSVs in cCREs and characterized their putative effects on TF binding. The approach integrates multiomics datasets for validation experiments using disease models.

AbstractSingle atom alloy (SAA) catalysts have been recently explored for promotion of various heterogeneous catalysis, but it remains unexplored for selective electrocatalytic reduction of carbon dioxide (CO2) into multi‐carbon (C2+) products involving C−C coupling. Herein we report a single‐atomic Bi decorated Cu alloy (denoted as BiCu‐SAA) electrocatalyst that could effectively modulate selectivity of CO2 reduction into C2+ products instead of previous C1 ones. The BiCu‐SAA catalyst exhibits remarkably superior selectivity of C2+ products with optimal Faradaic efficiency (FE) of 73.4 % compared to the pure copper nanoparticle or Bi nanoparticles‐decorated Cu nanocomposites, and its structure and performance can be well maintained at current density of 400 mA cm−2 under the flow cell system. Based on our in situ characterizations and density functional theory calculations, the BiCu‐SAA is found to favor the activation of CO2 and subsequent C−C coupling during the electrocatalytic reaction, as should be responsible for its extraordinary C2+ selectivity.
