A longitudinal study of risk and protective factors for symptoms of adjustment disorder during the COVID-19 pandemic

Background: The COVID-19 pandemic caused multiple stressors that may lead to symptoms of adjustment disorder. Objective: We longitudinally examined relationships between risk and protective factors, pandemic-related stressors and symptoms of adjustment disorder during the COVID-19 pandemic, as well as whether these relationships differed by the time of assessment. Method: The European Society for Traumatic Stress Studies (ESTSS) ADJUST Study included N = 15,169 participants aged 18 years and above. Participants from 11 European countries were recruited and screened three times at 6-month intervals from June 2020 to January 2022. Associations between risk and protective factors (e.g. gender), stressors (e.g. fear of infection), and symptoms of adjustment disorder (AjD, ADNM-8) and their interaction with time of assessment were examined using mixed linear regression. Results: The following predictors were significantly associated with higher AjD symptom levels: female or diverse gender; older age; pandemic-related news consumption &gt;30 min a day; a current or previous mental health disorder; trauma exposure before or during the pandemic; a good, satisfactory or poor health status (vs. very good); burden related to governmental crisis management and communication; fear of infection; restricted social contact; work-related problems; restricted activity; and difficult housing conditions. The following predictors were associated with lower AjD levels: self-employment or retirement; working in healthcare; and face-to-face contact ≥ once a week with loved ones or friends. The effects of the following predictors on AjD symptoms differed by the time of assessment in the course of the pandemic: a current or previous mental disorder; burden related to governmental crisis management; income reduction; and a current trauma exposure. Conclusions: We identified risk factors and stressors predicting AjD symptom levels at different stages of the pandemic. For some predictors, the effects on mental health may change at different stages of a pandemic.</p

Factores de riesgo y protectores para el trastorno de éstres postráumatico en individuos expuestos a trauma durante la pandemia COVID-19 – hallazgos de un estudio paneuropeo

Background: The COVID-19 pandemic is a health emergency resulting in multiple stressors that may be related to posttraumatic stress disorder (PTSD). Objective: This study examined relationships between risk and protective factors, pandemic-related stressors, and PTSD during the COVID-19 pandemic. Methods: Data from the European Society of Traumatic Stress Studies (ESTSS) ADJUST Study were used. N = 4,607 trauma-exposed participants aged 18 years and above were recruited from the general populations of eleven countries (Austria, Croatia, Georgia, Germany, Greece, Italy, Lithuania, the Netherlands, Poland, Portugal, and Sweden) from June to November 2020. We assessed sociodemographic (e.g. gender), pandemic-related (e.g. news consumption), and health-related (e.g. general health condition) risk and protective factors, pandemic-related stressors (e.g. fear of infection), and probable PTSD (PC-PTSD-5). The relationships between these variables were examined using logistic regression on multiple imputed data sets. Results: The prevalence of probable PTSD was 17.7%. Factors associated with an increased risk for PTSD were younger age, female gender, more than 3 h of daily pandemic-related news consumption (vs. no consumption), a satisfactory, poor, or very poor health condition (vs. a very good condition), a current or previous diagnosis of a mental disorder, and trauma exposure during the COVID-19 pandemic. Factors associated with a reduced risk for PTSD included a medium and high income (vs. very low income), face-to-face contact less than once a week or 3–7 times a week (vs. no contact), and digital social contact less than once a week or 1–7 days a week (vs. no contact). Pandemic-related stressors associated with an increased risk for PTSD included governmental crisis management and communication, restricted resources, restricted social contact, and difficult housing conditions. Conclusion: We identified risk and protective factors as well as stressors that may help identify trauma-exposed individuals at risk for PTSD, enabling more efficient and rapid access to care.Antecedentes: La pandemia COVID-19 es una emergencia sanitaria que genera múltiples estresores que pueden estar relacionados con el trastorno de estrés postraumático (TEPT). Objetivo: Este estudio examinó las relaciones entre los factores de riesgo y protectores, estresores relacionados con la pandemia y TEPT durante la pandemia de COVID-19. Métodos: Se utilizaron los datos del estudio ADJUST de la Sociedad Europea de Estudios de Estrés Traumático (ESTSS por sus siglas en ingles). N=4.607 participantes mayores de 18 años expuestos a trauma fueron reclutados de la población general de once países (Austria, Croacia, Georgia, Alemania, Grecia, Italia, Lituania, Países Bajos, Polonia, Portugal y Suecia) desde junio a noviembre 2020. Evaluamos factores de riesgo y protectores sociodemográficos (p.ej. género), relacionados con la pandemia (p.ej. consumo de noticias) y relacionados con la salud (p.ej. estado de salud general), estresores relacionados con la pandemia (p.ej. temor a la infección) y TEPT probable (PC-PTSD-5 por sus siglas en ingles). Las relaciones entre estas variables se examinaron mediante regresión logística en múltiples conjuntos de datos imputados. Resultados: La prevalencia de TEPT probable fue del 17.7%. Los factores asociados con un mayor riesgo de TEPT fueron edad más joven, sexo femenino, más de 3 horas de consumo diario de noticias relacionadas con la pandemia (frente a ningún consumo), un estado de salud satisfactorio, malo o muy malo (frente a un estado muy bueno), un diagnóstico de trastorno mental actual o previo y exposición a un trauma durante la pandemia de COVID-19. Los factores asociados con un riesgo reducido de TEPT incluyeron ingresos medios y altos (frente a ingresos muy bajos), contacto cara a cara menos de una vez a la semana o de 3 a 7 veces por semana (frente a ningún contacto) y contacto social digital menos de una vez a la semana o de 1 a 7 días a la semana (frente a ningún contacto). Los estresores relacionados con la pandemia asociados con un mayor riesgo de TEPT incluyeron la gestión y comunicación de crisis gubernamental, recursos restringidos, contacto social restringido y condiciones de vivienda difíciles. Conclusiones: Identificamos factores de riesgo y protectores, así como estresores que pueden ayudar a identificar a las personas expuestas a traumas en riesgo de TEPT, lo que permite un acceso más eficiente y rápido a la atención

Experiments on the Parallel Hall Effect in Three-Dimensional Metamaterials

International audienceThe classical Hall effect in ordinary isotropic conducting materials describes the occurrence of a voltageperpendicular to the direction of the electric-current flow and perpendicular to the imposed magnetic-fieldvector. The Hall effect is routinely used in magnetic-field sensors. Here, we fabricate and characterizemicrostructured anisotropic metamaterials composed of a single semiconducting constituent (n-type ZnO)for which the direction and the sign of the Hall electric field can be tailored by microstructure. This classof metamaterials includes the possibility of a Hall voltage parallel—rather than perpendicular—to themagnetic-field vector. One possible future application arising from this far-reaching control of the effectiveelectric-conductivity tensor is a sensor measuring the circulation of a magnetic field

Ultraviolet dual comb spectroscopy: a roadmap

Dual Comb Spectroscopy proved its versatile capabilities in molecular fingerprinting in different spectral regions, but not yet in the ultraviolet (UV). Unlocking this spectral window would expand fingerprinting to the electronic energy structure of matter.This will access the prime triggers of photo-chemical reactions with unprecedented spectral resolution. In this research article, we discuss the milestones marking the way to the first UV dual comb spectrometer. We present experimental and simulated studies towards UV dual comb spectroscopy, directly applied to planned absorption measurements of formaldehyde (centered at 343 nm, 3.6 eV) and argon (80 nm, 16 eV). This will enable an unparalleled relative resolution of up to $10^{-9}$ - with a table-top UV source surpassing any synchrotron linked spectrometer by at least two and any grating-based UV spectrometer by up to six orders of magnitude
