Longitudinal Assessment of Hair Cortisol as a Predictor of Psychological Symptoms During COVID-19.

BACKGROUND: There is a lack of evidence regarding enduring psychoneuroendocrine changes following an initial traumatic event, particular in the presence of an ongoing stressor. The coronavirus pandemic presents an opportunity to explore this matter. Consequently, the purpose of the present study was to investigate the impact of the ongoing pandemic (2021) on individuals, who experienced a first-time motor vehicle crash (MVC) at least 6 years earlier. To this end, we hypothesized that hair cortisol concentrations (HCC) following a first-time traumatic event positively predict symptoms of depression. METHOD: We investigated N = 69 individuals (18 - 65 yrs.), who were victims of a MVC during 2010 - 2014. Hair strands were collected 10 days (t1) and 3 months after the MVC (t2), as well during the pandemic in 2021 (t3). To assess symptoms of depression, the participants filled out the Beck Depression Inventory at t1 - t3 and were additionally interviewed (Structured Clinical Interview for DSM-IV Axis I) at t1 and t2. Exclusion criteria conveyed a lifetime or acute mental disorder (incl. past trauma exposure). RESULTS: Elevated pre-pandemic HCC following adversity (i.e., MVC) significantly predicted symptoms of depression in adults during the coronavirus pandemic (BDI: ß =.44, p =.010, R2 =.20), even after controlling for confounders. HCC significantly decreased over time, while in average psychological symptoms remained consistent. CONCLUSION: Cortisol dysregulation in the past presents an enduring vulnerability to ongoing stress. In this regard, vulnerable groups may benefit from preventive measures. This finding validates the predictive power of HCC and extended past evidence in this regard, at the same time reinforcing the concept of the diathesis-stress model.

[Critical incidents with medical products]. / Kritische Ereignisse mit Medizinprodukten.

Various vigilance systems have been established in medicine during the last two decades. The aims are the identification of critical incidents and to implement appropriate countermeasures thus decreasing the likelihood of accidents and increasing patient and user safety. The types of systems are very divergent: they are either restricted to individual departments, hospitals, specialist or occupational groups or function nationwide. The legislative provision for medical products also includes critical incident surveillance and reporting systems and focuses on the subset of events with involvement of medical products. The responsible German authority is the Federal Institute for Drugs and Medical Products which contacts manufacturers and informs users. This article describes experiences with the responsible authority. Not all users are aware that an obligation for reporting exists. A proposal is made to simplify the reporting process in order to enhance user willingness for reporting. Additionally, it is suggested that a link should be incorporated into all existing critical incident reporting systems which can forward the user to the specific reporting website.
