Cancer is considered one of the dominant life-threatening diseases in children. Working in the field of pediatric oncology, although rewarding, can be a source of stress and emotional burden for health care providers. The aim of this systematic review was to summarise the evidence regarding the occupational stress of health care providers working with pediatric cancer patients. Extensive search of the Pubmed and Scopus databases was performed to identify studies relevant to the topic. Initial search retrieved 657 studies. The reviewing investigators, after applying the inclusion/exclusion criteria, extracted data to critically appraise the quality of evidence. The final step of search concluded in 23 studies of heterogeneous design. Results revealed two main domains of which occupational stress derived from i) the interaction of the health care provider with the patient and the family, and ii) several organisational factors, such as hierarchical structures, experience, workload, and low organisational support. Literature on the stress of pediatric oncology staff is limited. The rather small sample sizes of the studies, the heterogeneity of methodological design, the lack of assessment from a sociological point of view, as well as the limited psychometric instruments adapted to pediatric oncology staff, make the validity of the results questionable. Further research is warranted to obtain a more accurate view of the field, to identify a cause-effect relation between work-related stress and pediatric oncology staff, and, more importantly, to guide future recommendations on support systems and stress management training within pediatric oncology settings.

Objective Multiple sclerosis (MS) is an autoimmune disorder of the central nervous system affecting patients’ well-being and quality of life. Pythagorean Self-Awareness Intervention (PSAI) is a novel non-pharmaceutical intervention with significant benefits both in MS and other chronic diseases. In this study, the longstanding effectiveness of PSAI was investigated. Method This was a two-arm quasi-experimental pragmatic trial in relapsing–remitting MS patients (23 in the PSAI and 21 in the control group). PSAI patients received an 8-week training period and then they performed PSAI at home for another 16 weeks. Assessments took place at baseline, 8 weeks, and 24 weeks. These included cognition, fatigue, perceived stress, and hair cortisol. Results Significant group × time interactions favoring PSAI were found during the first 8-week period for information processing speed, fatigue, and perceived stress. However, only verbal memory was found to be significantly improved in the PSAI group during the 24-week follow-up period. There were no significant group × time differences with respect to hair cortisol. No side effects were noted and compliance was excellent. Conclusions PSAI was mostly effective during the first 8-week training period. Its benefits worn out during the non-training period, albeit we observed a delayed significant improvement of verbal memory. Our findings will help to further refine the technique, either by extending the training period and/or by including booster sessions, throughout the PSAI treatment. This study provided Class III evidence for PSAI.
