Model of structural equations on the perception of aspects of school life and substance consumption as predictors of problem behavior in adolescents.

Introduction: Problematic behavior and drug use are behaviors of social concern, especially in adolescence. There are school factors that can contribute to their development or prevent them. The objective was to establish explanatory models of the relationship between various school variables with the consumption of alcohol, tobacco and cannabis; determining its direct and/or indirect relationship with problematic behaviors.

Optimism as a key factor in coping with the common cold.

Objective: The optimism trait is considered one of the most important psychological factors in protecting and promoting health. This study aims to investigate whether trait optimism may help to cope better with the common cold by reducing the subjective perception of cold symptoms and affecting the immune response.

Methods: To do so, 212 volunteers from the Pittsburg Cold Study 3 within the Common Cold Project were exposed to Rhinovirus (RV39).

Burnout is related to executive dysfunction in primary healthcare professionals working in rural areas.

Introduction: Healthcare professionals are especially vulnerable to burnout, which implies a hypothalamus-pituitary-adrenal dysregulation that could impact the integrity of brain structures needed for cognitive processing. However, a scarce number of studies have analyzed the relationship between burnout and executive functions in this population, and possible modulator factors have not been clarified. This study aims to characterize the burnout level of primary healthcare professionals working in rural areas, and to analyze its relationship with executive functioning, considering the possible modulating role of optimism.

Effectiveness of virtual reality-based neuropsychological interventions in improving cognitive functioning in patients with mild cognitive impairment: A systematic review and meta-analysis.

Increased prevalence of mild cognitive impairment (MCI) has led to a need for new neuropsychological intervention tools in this population. This meta-analysis aimed to learn about the efficacy of virtual reality (VR)-based neuropsychological interventions in improving cognitive functioning in patients with MCI. This review followed the recommendations of the PRISMA statement, and it was registered in PROSPERO.

Effects of psychological stress and cortisol on decision making and modulating factors: A systematic review.

Evidence suggests that psychological stress has effects on decision making, but the results are inconsistent, and the influence of cortisol and other modulating factors remains unclear. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, 18 studies carried out between 2015 and 2020 that examined the effects of psychological stress on decision making and measured cortisol levels were selected. Eight studies employed uncertainty-based economic tasks, five studies used decision-making tasks in hypothetical situations that can be encountered in real life or in a specific setting and five studies employed prosocial decision tasks.
