Stressors related to the COVID-19 pandemic and their association with distress, depressive, and anxiety symptoms in cancer out-patients.

Patients with cancer might be particularly prone to stress caused by the COVID-19 pandemic. The aim of this study was to investigate the impact of pandemic-related stressors on oncological patients' psychological well-being. During the second wave of the COVID-19 pandemic in Germany 122 cancer out-patients of the Comprehensive Cancer Center Munich reported on COVID-19-related stressors (information satisfaction, threat perception, and fear of disease deterioration) and answered standardized questionnaires for psychosocial distress (DT) as well as depression and anxiety symptoms (PHQ-2, GAD-2). Multiple linear regression analyses were used to identify associations of the COVID-19-related stressors with psychological symptoms, controlling for sociodemographic, psychological (self-efficacy, ASKU) and clinical (somatic symptom burden, SSS-8) variables. Initially, satisfaction with information was significantly negatively associated with all three outcome variables. Fear of disease deterioration was associated with distress and depressive symptoms. After controlling for additional variables, only satisfaction with information remained an independent determinant of anxiety (ß = -0.35, p < 0.001). All three outcomes were most strongly determined by somatic symptom burden (ß ≥ 0.40, p < 0.001). The results of this study tentatively suggest that physical well-being overrides the relevance of some COVID-19-related stressors for oncological patients' psychological wellbeing. Physical symptoms are strongly tied to personal wellbeing as they are associated with suffering from cancer, which might be more central to personal wellbeing than the possibility of getting infected with SARS-CoV-2. However, satisfaction with the information received seems to be important beyond physical wellbeing, as this emerged as an independent determinant of anxiety.

BACKGROUND: This study investigates current needs and psychosocial burden of out-patients with cancer during the COVID-19-Pandemic. MATERIAL AND METHODS: Between 11/2020 and 02/2021 122 cancer patients who underwent out-patient treatment at the Comprehensive Cancer Center Munich participated in the study. Based on a standardized, semi-structured interview, participants were asked about their knowledge and informational needs related to COVID-19, risk perception and concerns regarding continuing out-patient treatment, COVID-19 related distress, confidence in the national health system, and their readiness to get vaccinated against COVID-19. Additionally, patients filled out the distress thermometer (DT). RESULTS: More than a third of the patients (34,2 %, n = 41/120) wanted to receive more information about the effects of the coronavirus on their cancer and their treatment. 17,2 % (n = 21/122) had faced changes concerning their current or planned treatment. 42/121 (34,7 %) of the patients were clinically distressed (DT ≥ 5). A possible overload of the health care system was the most commonly reported COVID-related concern (77,9 %, n = 95/122), followed by being concerned that their family members might be additionally worried about them (56,2 %, n = 68/121). 71,2 % (n = 74/104) of the patients are willing to be vaccinated; 60 % (n = 18/30) of those undecided or refusing at the time of the survey expressed a desire to have a consultation with an oncologist before giving their final consent to vaccination. DISCUSSION: Corona-specific distress of cancer patients relates in particular to the course of therapy, but also to a possible overload of the health care system. Oncology care teams should allow space for questions from their patients, acknowledge possible uncertainties, provide emotional support, and draw attention to reliable sources of information.

Distress in hospitalized cancer patients: Associations with personality traits, clinical and psychosocial characteristics.

OBJECTIVE: To improve allocation of psychosocial care and to provide patient-oriented support offers, identification of determinants of elevated distress is needed. So far, there is a lack of evidence investigating the interplay between individual disposition and current clinical and psychosocial determinants of distress in the inpatient setting. METHODS: In this cross-sectional study, we investigated 879 inpatients with different cancer sites treated in a German Comprehensive Cancer Center. Assessment of determinants of elevated distress included sociodemographic, clinical and psychosocial characteristics as well as dimensions of personality. Multiple linear regression was applied to identify determinants of psychosocial distress. RESULTS: Mean age of the patients was M = 61.9 (SD = 11.8), 48.1% were women. In the multiple linear regression model younger age (ß = -0.061, p = 0.033), higher neuroticism (ß = 0.178, p = <0.001), having metastases (ß = 0.091, p = 0.002), being in a worse physical condition (ß = 0.380, p = <0.001), depressive symptoms (ß = 0.270, p = <0.001), not feeling well informed about psychological support (ß = 0.054, p = 0.046) and previous uptake of psychological treatment (ß = 0.067, p = 0.020) showed significant associations with higher psychosocial distress. The adjusted R2 of the overall model was 0.464. CONCLUSION: Controlling for sociodemographic characteristics and dispositional vulnerability, that is neuroticism, current clinical and psychosocial characteristics were still associated with hospitalized patients' psychosocial distress. Psycho-oncologists should address both, the more transient emotional responses, such as depressive symptoms, as well as more enduring patient characteristics, like neuroticism.

Measured and predicted acute toxicity of phenanthrene and MC252 crude oil to vertically migrating deep-sea crustaceans.

Deep-water column micronekton play a key role in oceanic food webs and represent an important trophic link between deep- and shallow-water ecosystems. Thus, the potential impacts of sub-surface hydrocarbon plumes on these organisms are critical to developing a more complete understanding of ocean-wide effects resulting from deep-sea oil spills. This work was designed to advance the understanding of hydrocarbon toxicity in several ecologically important deep-sea micronekton species using controlled laboratory exposures aimed at determining lethal threshold exposure levels. The current study confirmed the results previously determined for five deep-sea micronekton by measuring lethal threshold levels for phenanthrene between 81.2 and 277.5 µg/L. These results were used to calibrate the target lipid model and to calculate a critical target lipid body burden for each species. In addition, an oil solubility model was used to predict the acute toxicity of MC252 crude oil to vertically migrating crustaceans, Janicella spinacauda and Euphausiidae spp., and to compare the predictions with results of a 48-h constant exposure toxicity test with passive-dosing. Results confirmed that the tested deep-sea micronekton appear more sensitive than many other organisms when exposed to dissolved oil, but baseline stress complicated interpretation of results.
