Developing a Health Game to Prepare Preschool Children for Anesthesia: Formative Study Using a Child-Centered Approach.

BACKGROUND: Every year, millions of children undergo medical procedures that require anesthesia. Fear and anxiety are common among young children undergoing such procedures and can interfere with the child's recovery and well-being. Relaxation, distraction, and education are methods that can be used to prepare children and help them cope with fear and anxiety, and serious games may be a suitable medium for these purposes. User-centered design emphasizes the involvement of end users during the development and testing of products, but involving young, preschool children may be challenging. OBJECTIVE: One objective of this study was to describe the development and usability of a computer-based educational health game intended for preschool children to prepare them for upcoming anesthesia. A further objective was to describe the lessons learned from using a child-centered approach with the young target group. METHODS: A formative mixed methods child (user)-centered study design was used to develop and test the usability of the game. Preschool children (4-6 years old) informed the game design through playful workshops (n=26), and usability testing was conducted through game-playing and interviews (n=16). Data were collected in Iceland and Finland with video-recorded direct observation and interviews, as well as children's drawings, and analyzed with content analysis and descriptive statistics. RESULTS: The children shared their knowledge and ideas about hospitals, different emotions, and their preferences concerning game elements. Testing revealed the high usability of the game and provided important information that was used to modify the game before publishing and that will be used in its further development. CONCLUSIONS: Preschool children can inform game design through playful workshops about health-related subjects that they are not necessarily familiar with but that are relevant for them. The game's usability was improved with the participation of the target group, and the game is now ready for clinical testing.

Retinal oxygen metabolism in patients with mild cognitive impairment.

INTRODUCTION: We have previously reported that retinal vessel oxygen saturation is increased in mild-to-moderate dementia of Alzheimer's type when compared with healthy individuals. Mild cognitive impairment (MCI) is the predementia stage of the disease. The main purpose was to investigate if these changes are seen in MCI. METHODS: Retinal vessel oxygen saturation was measured in 42 patients with MCI and 42 healthy individuals with a noninvasive retinal oximeter, Oxymap T1. The groups were paired according to age. RESULTS: Arteriolar and venular oxygen saturation was increased in MCI patients compared to healthy individuals (arterioles: 93.1 ± 3.7% vs. 91.1 ± 3.4%, P = .01; venules: 59.6 ± 6.1% vs. 54.9 ± 6.4%, P = .001). Arteriovenous difference was decreased in MCI compared to healthy individuals (33.5 ± 4.5% vs. 36.2 ± 5.2%, P = .01). DISCUSSION: Increased retinal vessel oxygen saturation and decreased arteriovenous difference in MCI could reflect less oxygen extraction by retinal tissue. This indicates that retinal oxygen metabolism may be affected in patients with MCI.

[Results of immediate breast reconstructions at Landspítali-The National University Hospital of Iceland, in 2008-2010]. / Tídni og árangur tafarlausra brjóstauppbygginga á Landspítala 2008-2010.

INTRODUCTION: In late 2007, the availability of immediate breast reconstructions increased as a result of the establishment of an oncoplastic breast surgical service at Landspítali-The National University Hospital The aim of this study was to look at the rates and early complications of immediate breast reconstructions in our hospital in 2008-2010 and compare with the results from the UK National Mastectomy and Breast Reconstruction Audit (NMBRA). MATERIAL AND METHODS: This is a retrospective population-based study, including all women who had immediate breast reconstruction at Landspítali in 2008-2010. RESULTS: 319 mastectomies and 157 breast reconstructions were performed. Of these, 98 (62%) were immediate, (mean age 49, 29-69). The immediate breast reconstruction rate was therefore 31%, with a respective 55% for patients 50 years old or younger. In comparison, the rate was 5% in 2000-2005. Immediate reconstructions with an extended autologous latissimus dorsi flap were performed in 25 (26%) cases and implant based reconstructions in the remaining (n=73, 74%). Inpatient complications occurred in 12 (12%) patients and 5 needed reoperation (3 post-operative bleeding, 1 skin necrosis, 1 imminent LD-flap failure). Readmission due to complications after discharge occurred in 14 (14%), while 37 (38%) developed mild complications not requiring readmission. The results were comparable to NMBRA, although the rates of autologous flap reconstructions were significantly higher than in this study (63% vs. 26%). CONCLUSION: As a result of the establishment of an oncoplastic breast surgical service at Landspítali, the rates of immediate breast reconstruction have increased significantly (from 5% to 31%). The complication rates are low and similar to NMBRA.

The impact of dispositional emotional expressivity and social constraints on distress among prostate cancer patients in Iceland.

OBJECTIVES: The aim of our study was to identify individual factors that may predict which subset of prostate cancer patients is more likely to experience emotional distress. DESIGN AND METHODS: Prostate cancer survivors identified through the Icelandic Cancer Registry (N=184), completed questionnaires measuring emotional distress, dispositional emotional expressivity and social constraints. RESULTS: A significant positive relationship was observed between perceived social constraints and distress (e.g. anxiety, depression, and intrusive thoughts), but only among prostate cancer survivors with higher levels of dispositional emotional expressivity. CONCLUSIONS: The results of our study suggest that it might be important to assess individual differences as well as social environmental factors in the treatment of distress among prostate cancer survivors.
