Patient experiences and the influence on health literacy and self-care using mHealth to manage symptoms during radiotherapy for prostate cancer
- 2019

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: Prostate cancer is a diagnosis that can affect the men’s quality of life both due to the symptoms related to the disease and the treatment the men receive. Treatment with radiotherapy for prostate cancer in Sweden takes place at outpatient clinics, where the patient visits daily for radiotherapy and then returns home. Most of the time the patient is experiencing the symptoms and side-effects at home without health-care professionals easily accessible. To facilitate person-centered care and improve clinical management when hospital care is moving to outpatient care, the app (Interaktor) for smartphones and tablets was developed. Using patient-reported outcomes (PRO), the app was intended to identify symptoms early, assess them in real time, and provide symptom-management support during radiotherapy for prostate cancer. Aims: The overall objective of the intervention described in this thesis, was to facilitate symptom management for patients with prostate cancer assisted with an interactive app during radiotherapy treatment.Methods: The two studies included in this thesis come from one trial. A descriptive investigation evaluated the intervention group’s use and perception of the using the app, and a quasi-experimental investigation compared those using the app with a historical control group not using the app to evaluate the effect on health literacy and self-care agency. The patients (n=130) were recruited consecutively from two university hospitals in Sweden between April 2012 and October 2013. The intervention group (n=66) had access to the app during 5-7 weeks of radiotherapy and three additional weeks. The intervention group’s use of the app was logged. Health literacy was measured using the Swedish Functional Health Literacy Scale (FHL) and the Swedish Communicative and Critical Health Literacy Scale (CCHL), and the Appraisal of Self-care Agency scale, version A (patient’s assessment) (ASA-A) for self-care agency. Transcribed notes from phone or face-to-face interviews about participants’ experiences of using and reporting in the app were analyzed.Results: In the intervention group using the app, adherence to daily reports was 87% (Md 92%, 16-100%), and generated 3,536 reports. All listed symptoms were used, where the most common being: urinary urgency, fatigue, hot flushes, and difficulties in urinating. A total of 1,566 alerts were generated, with 1/3 being severe (red alert). The app was reported in the interviews as easy to use, the reporting became routine; to report facilitated reflection over symptoms, the symptoms were relevant although some found that nuancing severity was hard. Using the app was reported as providing a sense of security. Substantial portions of the participants showed inadequate FHL and CCHL at baseline for both groups. CCHL changed significantly for the intervention group from baseline to three months after ended treatment (p = 0.050). Functional health literacy and self-care agency did not reveal any statistically significant differences over time for either group. Conclusions: The conclusions to draw from this thesis are that an mHealth intervention, the app Interaktor, served as a supportive tool for the patients to assess and manage symptoms during the radiotherapy for prostate cancer. The intervention provided the patients with a sense of safety, increased awareness of own well-being and a significant improvement in communicative and critical health literacy was found. The portions of inadequate levels of health literacy reported leave substantial groups of patients more vulnerable in assessing and managing symptoms when treated with radiotherapy for prostate cancer. Although health literacy levels include notable portions of patients in this study that have inadequate levels of both functional and communicative and critical health literacy, the adherence of using the app was high.

- Background. Given the growing prevalence of overweight and related health consequences, there is increased interest in the search for novel dietary strategies for weight control. A food ingredient, an emulsion based on palm and oat oil (Fabuless, previously known as Olibra), has been associated with short-term reductions of food intake, induction of satiety, alternation in the satiety hormones, as well as long-term effects on weight control. The mechanism by which it can exert these effects is so far unclear, though it has been suggested that the "ileal break'' may play a role in increasing gastrointestinal transit time. The aim of this study was to investigate the effects of this stable fat emulsion on orocecal transit time in healthy men. Material and methods. In a controlled, double-blind, cross-over-designed study, 15 healthy men (aged 20-59 years, body mass index (BMI) 22-28), randomly allocated to two treatments, consumed the stable fat emulsion or a milk fat in yoghurt during two days of investigation, with an interval of 1 week. Orocecal transit time was determined by following blood sulfapyridine levels, which is a metabolite of salazopyrine in the colon. Results. A statistically significant delay in the appearance of sulfapyridine in serum was obtained after active treatment versus control treatment, corresponding to a 45-min longer orocecal transit time due to fat emulsion consumption. Conclusions. This study provides the first evidence to suggest that this stable fat emulsion may affect the ileal brake mechanism by slowing down the gastrointestinal transit time, which might explain the weight control and appetite suppression previously observed in association with this emulsion.

- Background: Whole-grain foods and cereal dietary fiber intake is associated with lower body weight. This may partly result from lower energy utilization of high-fiber diets. Objective: In the present study, the impact on ileal excretion of energy and macronutrients in response to a rye bread high-fiber diet compared to a refined wheat low-fiber diet was investigated. Furthermore, the effect of meal frequency on apparent absorption of nutrients was studied for the first time. Design: Ten participants that had undergone ileostomy consumed standardized iso-caloric diets, including low-fiber wheat bread (20 g dietary fiber per day) for 2 weeks followed by high-fiber rye bread (52 g dietary fiber per day) for 2 weeks. The diets were consumed in an ordinary (three meals per day) and a nibbling (seven meals per day) meal frequency in a cross-over design. Ileal effluents were collected during 24 h at the third day of each of the four dietary periods and analyzed for gross energy and nutrient contents. Results: The results showed that intake of rye bread high-fiber diet compared to the refined wheat low-fiber diet caused an increase in ileal excretion of energy and macronutrients. The effect was independent of meal frequency. This suggests that a high intake of rye may result in lower availability of macronutrients for small intestinal digestion and absorption. A regular intake of rye may therefore have implications for weight management.

- The maintenance of an obtained lower weight level is often found to be difficult. The aim of this study was to determine weight maintenance after an initial weight loss by consumption of a meal replacement with a vegetable-oil emulsion associated with prolonged satiety. After a 6-week weight loss period with very low calorie diet (VLCD), subjects with > 5% body weight (BW) loss were randomized to a 12-week weight maintenance follow-up period, comparing a partial meal replacement diet containing a vegetable-oil emulsion (test) or dairy fat (control). Anthropometric data and safety variables were collected at baseline and after 4, 8 and 12 weeks. A significant weight loss was observed during the 12-week weight maintenance diet in the test and control group, respectively; 1.0 +/- A 2.1 kg (p < 0.05) versus 1.3 +/- A 2.1 kg (p < 0.05) with no significant difference between the groups. Body fat mass (BFM) decreased significantly (p < 0.05) in the test group (-1.7%) compared to the control group (-0.8%). Addition of a vegetable-oil emulsion to a meal replacement weight maintenance program after an initial weight loss using VLCD was associated with decreased BFM by 0.9% without any change in BW between the two groups.

- Current organic agriculture performs well in several sustainability domains, like animal welfare, farm profitability and low pesticide use, but yields are commonly lower than in conventional farming. There is now a re-vitalized interest in increasing yields in organic agriculture to provide more organic food for a growing, more affluent population and reduce negative impacts per unit produced. However, past yield increases have been accompanied by several negative side-effects. Here, we review risks and opportunities related to a broad range of sustainability domains associated with increasing yields in organic agriculture in the Northern European context. We identify increased N input, weed, disease and pest control, improved livestock feeding, breeding for higher yields and reduced losses as the main measures for yield increases. We review the implications of their implementation for biodiversity, greenhouse gas emissions, nutrient losses, soil fertility, animal health and welfare, human nutrition and health and farm profitability. Our findings from this first-of-its-kind integrated analysis reveal which strategies for increasing yields are unlikely to produce negative side-effects and therefore should be a high priority, and which strategies need to be implemented with great attention to trade-offs. For example, increased N inputs in cropping carry many risks and few opportunities, whereas there are many risk-free opportunities for improved pest control through the management of ecosystem services. For most yield increasing strategies, both risks and opportunities arise, and the actual effect depends on management including active mitigation of side-effects. Our review shows that, to be a driving force for increased food system sustainability, organic agriculture may need to reconsider certain fundamental principles. Novel plant nutrient sources, including increased nutrient recycling in society, and in some cases mineral nitrogen fertilisers from renewable sources, and truly alternative animal production systems may need to be developed and accepted.
