Purpose: Although the medical decision-making process can be overwhelming for some surrogates, there is a lack of understanding regarding their experiences. The objectives of this study were to examine the decision self-efficacy and decisional conflict experienced by surrogates in intensive care units (ICUs) when faced with the decision of whether to reintubate patients with respiratory failure after a planned extubation. In addition, predictors and mediators influencing these decision-making processes were identified. Methods: This study utilized a cross-sectional design to investigate the decision-making processes of 174 surrogates who were faced with the decision of whether to reintubate patients with respiratory failure after a planned extubation in the internal ICU of a medical center between August 2021 and February 2022. Structured questionnaires were administered to collect data on the surrogates' background information, decision self-efficacy, decisional conflict, and positive and negative affect. The patients’ background information was also collected. Univariate and multivariate analyses were performed to model the data. Results: The mean decision self-efficacy score of the surrogates was 82.41 points, and 20.7% surrogates had decisional conflict scores exceeding 37.5 points, suggesting that they faced challenges in the decision-making process. Surrogates' employment status and negative affect significantly predicted their decision self-efficacy. In addition, patients' activities of daily living prior to hospitalization and the decision self-efficacy of the surrogate significantly predicted surrogate decisional conflict. The impact of surrogates’ negative affect on decisional conflict was fully mediated by decision self-efficacy. Conclusions Surrogate decision self-efficacy mediates the relationship between negative affect and decisional conflict. Providing clinical care interventions that focus on enhancing surrogate self-efficacy and reducing negative affect can help alleviate decisional conflict in this population.

The clinical spectrum of infections caused by non-typhoid Salmonella spp. includes gastroenteritis, enteric fever, bacteremia, and extraintestinal localized complications, especially in immunocompromised hosts. Here we report a patient with severe aplastic anemia developing left iliopsoas abscess caused by non-typhoid Salmonella (NTS), which was successfully treated by prolonged antibiotic treatment and repeated debridement. Our data indicate that aplastic anemia is a risk factor for infection caused by NTS.

Objective: Schizophrenia has been associated with dysfunction of the hypothalamic-pituitary-adrenal axis. Furthermore, alterations in neurotrophic factors might contribute to the pathogenesis of schizophrenia. We aimed to evaluate the effects of a simulated laughter intervention on the levels of cortisol and BDNF and to determine whether the effects associated with simulated laughter could be sustained after discontinuation of the intervention. Methods: In this randomized controlled study, patients with schizophrenia according to DSM-IV clinical criteria were randomly assigned to receive either 8-week-long simulated laughter intervention (n=32) or treatment-as-usual group (control group, n=27). The serum levels of BDNF and cortisol were measured at baseline, week 8, and four weeks after discontinuation (week 12) of the intervention program. Results: After an 8-week simulated laughter intervention, the laughter group had significantly higher levels of BDNF; however, four weeks after discontinuation of the intervention, the levels of BDNF significantly dropped. Interestingly, the levels of cortisol did not change significantly at week 8, but they were significantly elevated at week 12. The levels of BDNF and cortisol in the control group did not change significantly between week 0 and week 8. Conclusion These findings suggest that the simulated laughter intervention has an early effect on neurogenesis with a significant delayed effect on stress regulation in subjects with schizophrenia.
