Life Strategies, Work and Health in People with Usher Syndrome
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: People with Usher syndrome (USH) have an inherited disorder causing congenital deafness or hearing loss combined with progressive vision loss and, in some cases, balance problems. Previous research has shown that people with USH have poor physical and psychological health. Research has, however, demonstrated that there are in-group health differences that have not yet been explored and that there is a lack of studies on life strategies as well as health in relation to working life.Aim: The aim was to explore the relationship between work and health in people with USH1 and 2 and to explore the experiences of life strategies in people with USH 2.Methods: A quantitative and a qualitative explorative design was employed comprising two cross-sectional studies of the relationship between work and health in people with USH2 (n=67) and USH1 (n=47). The third study, of life strategies, comprised focus group interviews with people with USH2a (n=14) analyzed by content analysis. The fourth study explored the lived experiences of working life by interviewing people with USH2 (n=7) using an interpretative phenomenological approach.Results: Study 1 and 2 demonstrated significant differences in health between working and nonworking people. Nonworking people showed significantly poorer health. In study 3, a variety of strategies to prevent and resolve challenges in life, as well as to comfort oneself was identified. The lived experiences of working life in people with USH2 (study 4) disclosed feelings of satisfaction, striving towards a work life balance. Work also disclosed feelings of limitations and uncertainty about the future.Conclusion: The results, which are discussed in relation to the Meikirsh model of health, demonstrated a complexity. Individual life strategies, psychological flexibility and environmental aspects, such as social determinants have to be considered to receive a comprehensive picture of the relationship between work and health in people with USH. This thesis provides new insights into the health of people with USH.

- Purpose: This study aimed to explore lived experiences with working life from the perspective of people with deafblindness due to Usher syndrome type 2 (USH2).Background: A limited number of studies have explored working life of people with Usher syndrome. One study of individuals with USH2 showed that work active reported significantly better psychological health compared to non-working individuals.Methods: Seven participants aged 38-50 years with USH2 participated in interviews analysed by interpretative phenomenological analysis.Results: The analyses yielded four themes showing that work is a source of satisfaction and a commitment that needs to be balanced. It is also associated with facing limitations and feelings of uncertainty.Conclusion: Based on the psychology of work model we have demonstrated that work is associated with social connectedness, self-determination and a source of improved health outcomes. There are however also potential health hazards in people with USH2, indicating a need for balance between individual needs and resources, and an adapted environment, for maintaining or regaining health for actively working people with USH2.

Nanocarbon oxidation in the environmental transmission electron microscope - Disentangling the role of the electron beam

Tidskriftsartikel (refereegranskat)abstract
- Environmental transmission electron microscopy (ETEM) can provide unique insights into nanocarbon oxidation processes through atomic resolution and real time imaging of materials at high temperatures in reactive atmospheres. However, the electron beam can also influence the reaction rates, and even alter the processes entirely, complicating the interpretation of the in situ observations. Many mechanisms have been proposed to account for the impact of the electron beam, predominantly involving ionization of the oxidative gases to form more reactive species. However, these mechanisms have not been critically evaluated and compared to predictions from theory. Here, we evaluate the impact of the electron beam both qualitatively (oxidation mode and spatial extent) and quantitatively (oxidation rates), using high resolution imaging and electron energy loss spectroscopy, at different electron energies and dose rates. We demonstrate that transient defects generated by elastic scattering, forming highly active sites for carbon abstraction by oxygen, is the main mechanism for the enhanced oxidation rates observed in situ. This is evident from an insensitivity to electron energy and saturation of the effects at high electron dose rates. To avoid undue influence of the electron beam in future ETEM studies, we therefore recommend conditions where the intrinsic oxidation dominates over the beam-enhanced oxidation (note that no conditions are completely “safe”) and extensive comparisons with other methods.
