RESUMO

Introduction: Decision-making is not purely rational but highlighted by the influence of intuitive and emotional processes. Recently, researchers have focused more attention on understanding which environmental and personal features influence decision-making processes, and how. Objective and methods: On this study, we investigate whether Trait Anxiety moderates the impact of Post-Traumatic Stress (PTS) symptoms reported during COVID-19 pandemic on decision-making styles. Results: The study included 1,358 Brazilian participants (80% women) aged between 20 and 74 (M = 41.11; SD = 11.23) who responded to an online survey between May and August of the year 2021 of COVID-19 pandemic to The State-Trait Anxiety Inventory, The Decisions Styles Scale, The Impact of Event Scale - Revised and questions related to COVID-19. Through moderation analysis, we observed that experiencing PTS is associated with a higher tendency to biased/heuristic decision-making processes. Discussion: Trait Anxiety seems to influence how people respond to PTS symptoms on decision-making related processes. Subjects with higher Trait Anxiety reported lower tendency to appeal to rationality, especially under higher reported levels of PTS. Meanwhile, lower Trait Anxiety subjects exhibited more reason-based decision-making under higher rates of PTS. This work contributes to a deeper understanding of the interplay among environmental and individual differences on decision-making styles and helps to identify factors of vulnerability for poorer cognitive functioning on stressful scenarios.

RESUMO

BACKGROUND: After >2 years of the Coronavirus Disease-19 (COVID-19) pandemic, it is well established how sleep symptoms are rising, especially among healthcare workers (HCW). The aim of this study is to evaluate what features are associated with sleep disturbances in the HCW population. METHODS: Cross-sectional and longitudinal analysis of social and clinical variables associated with sleep problems and insomnia incidence in HCW in a large, national-level cohort. The measurement of sleep problems was assessed by self-report using Jenkins Sleep Scale (JSS). A multivariate analysis was used in the cross-sectional design and generalized linear models were used in the longitudinal design. RESULTS: 10,467 HCW were analyzed in the cross-sectional analysis, 3313 participants were analyzed in the three timepoints of the study. Sex, previously diagnosed mental illness and frontline work with COVID-19 were associated with higher scores in JSS in the univariate analysis. In the multivariate analysis, only previous diagnosis of mental illness was related with sleep difficulties, especially previously diagnosed insomnia. The longitudinal analysis concluded that previous diagnosis of mental illnesses was associated with higher levels of insomnia development (OR = 11.62). The self-reported disorders found to be major risk factors were addiction (OR = 7.69), generalized anxiety disorder (OR = 3.67), social anxiety (OR = 2.21) and bipolar disorder (OR = 2.21). LIMITATIONS: Attrition bias. CONCLUSIONS: Previous diagnosis of mental illness was strongly related to insomnia development in HCW during the COVID-19 pandemic. Strategies that focus on this population are advised.

RESUMO

BACKGROUND: Cytokines have been shown to be involved in traumatic brain injury (TBI). We investigated the independent association between serum levels of IL-10 and TNF-α and hospital mortality of patients with severe TBI. METHODS: Serum IL-10 and TNF-α levels were determined after a median period (interquartile range (IQ) 25-75) of 10 h (IQ 5-18) after severe TBI in 93 consecutive patients and in randomly selected patients with mild (n = 18) and moderate (n = 16) TBI. In patients with severe TBI, additional blood samples were analyzed 30 h (IQ 22-37) and 68 h (IQ 55-78) after TBI. Age, gender, computed tomography findings, Glasgow Coma Scale score (GCS) and pupil reactions at admission, associated trauma and hospital mortality were collected. RESULTS: Elevated serum levels of IL-10, but not TNF-α, correlated significantly with GCS severity (R(2) coefficient, p < 0.0001) and were found to be associated with hospital mortality in patients with severe TBI. Elevated IL-10 remained associated with mortality (p = 0.01) in a subset of patients with isolated severe TBI (n = 74). Multiple logistic regression analysis showed that higher IL-10 levels (>90 pg/ml) at 10 or 30 h after TBI were 6 times (odds ratio (OR) 6.2, 95% confidence interval (CI) 1.2-25.1, p = 0.03) and 5 times (OR 5.4, 95% CI 1.2-25.1, p = 0.03), respectively, more frequently associated with hospital mortality than lower levels (<50 pg/ml), independently of age, GCS as well as pupil reactions at admission and associated trauma. CONCLUSIONS: Serum IL-10 levels may be a useful marker for severe TBI prognosis.
