Traumatic stress reactions (TSRs) exist on a continuum that includes posttraumatic stress disorder (PTSD), highly comorbid psychopathology, and resilience, highlighting the need for comprehensive and integrative approaches capable of capturing the full spectrum of heterogeneous reactions. Here, we used a transdiagnostic and multidimensional method to characterize clinical phenotypes of TSRs in a nationally representative sample of U.S.

In line with the US Department of Veterans Affairs' adoption of a Whole Health approach to healthcare, there has been growing interest in factors linked to veterans' perceptions of well-being. To date, no known study has examined levels and correlates of perceived happiness in this population. To examine this question, we analyzed data from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 4,069 US military veterans.

Background And Objectives: To examine changes in clerical burden, including daily clerical time, daily after hours Electronic Health Record (EHR) time and EHR frustration between 2018 and 2022 among physician faculty, and identify sociodemographic and occupational correlates of clerical burden with burnout and intent to leave one's job (ILJ).

Methods: An institution-wide survey was sent to all physician faculty at an 8-Hospital Health System in New York City, between July and September 2022. Clerical time, after hours EHR time, practice unloading clerical burden and EHR frustration were assessed using ordinal-scale questions.

The substantial investment of funds from state and commercial sources has facilitated a significant increase in knowledge about these ingredients. Cannabinoids can be classified into three principal categories: plant-derived phytocannabinoids, synthetic cannabinoids and endogenous cannabinoids, along with the enzymes responsible for their synthesis and degradation.

To examine the prevalence and key correlates of psychological resilience in Ukrainian mental health workers (MHWs), using a novel discrepancy-based psychiatric resilience (DBPR) analytic approach. A total of 178 Ukrainian MHWs, recruited via convenience sampling from July to August 2023, completed a survey assessing their war-related exposures, occupational stress, and mental health symptoms and sociodemographic and psychosocial characteristics. DBPR scores were computed by regressing composite distress scores onto measures of war- and work-related stressors.

Objective: This study investigated the genetic and epigenetic mechanisms underlying the comorbidity patterns of five substance dependence diagnoses (SDs; alcohol, AD; cannabis, CaD; cocaine, CoD; opioid, OD; tobacco, TD).

Methods: A latent class analysis (LCA) was performed on 31,197 individuals (average age 42±11 years; 49% females) from six cohorts to identify comorbid DSM-IV SD patterns. In subsets of this sample, we tested SD-latent classes with respect to polygenic burden of psychiatric and behavioral traits and epigenome-wide changes in three population groups.

Background: Data on the potential protective effect of psychological safety (PS) on well-being and satisfaction among physicians are lacking.

Objective: We sought to examine (1) prevalence of PS; (2) relationship between PS, burnout, and intent to leave one's job (ILJ); and (3) demographic and occupational factors associated with PS within our physician faculty.

Design: Participants: An institution-wide survey was sent to all faculty within our eight-hospital health system, between July and September 2022.

Background: Posttraumatic stress disorder (PTSD) has become a main psychological consequence of COVID-19. This study assessed the association between social support, psychological resilience, and probable COVID-19-related PTSD.

Methods: The PTSD Checklist for DSM-5, Medical Outcomes Study Social Support Survey, and Connor-Davidson Resilience Scale (CD-RISC) were used to assess for PTSD symptoms, social support, and resilience among COVID-19 patients treated at a large medical system in New York City between July 2020 and July 2023.

Introduction: Although COVID-19 has affected health care and screening utilization, its impact on lung cancer screening (LCS) uptake remains unclear. Our study investigated LCS utilization and associated predictors among adults eligible for LCS before (2019), during (2020-2021), and at a later stage (2022) of COVID-19.

Methods: We used cross-sectional, nationally representative, population-based data from the Behavioral Risk Factor Surveillance System over 4 consecutive years: 2019 (n = 4484; weighted n = 1,559,37), 2020 (n = 1239; weighted n = 200,301), 2021 (n = 1673; weighted n = 668,359), and 2022 (n = 20,804; weighted n = 9,458,907).

The preparation of biocarbons from cellulose fibres utilised in the production of baby nappy mats (sourced from Feniks Recycling company, Poland) for the removal of methylene blue and rhodamine B dyes has been documented. A Brunauer, Emmett and Teller analysis revealed a surface area within the range of 384 to 450 m/g. The objective of this study was to investigate the removal efficiency of dyes from aqueous solutions by biocarbons, with a particular focus on the influence of various parameters, including pH, dye concentration, adsorbent dosage, shaking speed, contact time, and temperature.

Article Synopsis
  • A study found a strong link between antisocial personality disorder (ASPD) and various substance use disorders (SUD), specifically alcohol, cannabis, and tobacco use disorders.
  • The association was particularly significant for the "hazardous use" criteria across all SUDs, suggesting that individuals with ASPD often engage in riskier substance use.
  • Notably, ASPD was related to a lower likelihood of attempting to quit cocaine, indicating that those with ASPD may struggle more with cessation efforts for certain substances.
