The everyday life of young children through their cancer trajectory
- 2015

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The young child’s experiences of living with cancer are crucial to providing evidence based care. The overall aim of this thesis was to explore and describe experiences of health and functioning in the everyday life of young children with cancer, over a three year period from diagnosis, to provide insights and suggestions to improve evidence based care.The first and second papers in the series of four for this thesis used a qualitative content analysis to describe the child’s experiences shortly after diagnosis and six and 12 months later. The third paper used mixed methods to identify a comprehensive set of ICF-CY codes describing everyday health and functioning in the life of the young child with cancer. The fourth paper used the identified comprehensive set of ICF-CY codes to follow changes in everyday health and functioning over the study’s entire three year period from diagnosis.Entry into the health-illness transition was characterised by trauma and isolation. Health and functioning in everyday life was utterly changed and physical difficulties were at their peak. The passage through transition was characterised by an active striving on the part of the child to make a normal everyday life of the cancer experience. Difficulties affecting health and functioning in everyday life decreased and changed during the trajectory, though feelings of loneliness prevailed. A new period of stability in the child’s post treatment life was seen from two years after diagnosis and onwards, with (re)-entry to preschool/school and other social activities. However, an increase in difficulties with personal interactions with others and access to, and support from healthcare professionals was seen. Variances were seen within individual children’s’ trajectories.In summary it can be stated that the everyday life of young children with cancer changes over time and health care services are not always in phase with these changes. Young children living with cancer want to be participatory in their care and to have access to their parents as protectors.They need access to and ongoing contact with peers and preschool. Although physical difficulties in living an everyday life with cancer reduce over time, new difficulties emerge as the child post cancer treatment re-enters society. A structured follow-up throughout the cancer trajectory and not just during active treatment is necessary. A child-centered philosophy of care would guide the child towards attainment of health and well-being.Both the child’s own perspective and a child’s perspective as described by adults caring for them should be seen on a continuum, rather than as opposites. This view could help ensure that young children become visible and are listened to as valuable contributors to care planning. Knowledge of health-illness transition can be useful in illustrating everyday health and functioning through long term illness trajectories.

Forskningsöversikt (refereegranskat)abstract
- In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.

Tidskriftsartikel (refereegranskat)abstract
- Although pain is one of the most prevalent and bothersome symptoms children with cancer experience, evidence-based guidance regarding assessment and management is lacking. With 44 international, multidisciplinary healthcare professionals and nine patient representatives, we aimed to develop a clinical practice guideline (following GRADE methodology), addressing assessment and pharmacological, psychological, and physical management of tumor-, treatment-, and procedure-related pain in children with cancer. In this paper, we present our thorough methodology for this development, including the challenges we faced and how we approached these. This lays the foundation for our clinical practice guideline, for which there is a high clinical demand.
