- In adults and adolescents with asthma, use of ≥3 short-acting β2 -agonist (SABA) canisters/year is associated with increased exacerbation risk. Whether this association is present in younger children remains unknown. In this SABA use IN Asthma (SABINA) Junior study, we assessed the association of SABA collection with exacerbation risk in the general Swedish pediatric asthma population.This population-based cohort study utilized linked data from the Swedish national healthcare registries involving patients with asthma (<18 years) treated in secondary care between 2006-2015. Exacerbation risk, by baseline SABA collection (0-2 vs. ≥3 canisters, further examined as ordinal/continuous variable) and stratified on comorbid atopic disease (allergic rhinitis, dermatitis and eczema, and food/other allergies), was assessed for 1-year follow-up using negative binomial regression.Of 219,561 patients assessed, 45.4%, 31.7%, and 26.5% of patients aged 0-5, 6-11, and 12-17 years, respectively, collected ≥3 SABA canisters during the baseline year (high use). Collection of ≥3 SABA canisters (vs. 0-2) was associated with increased exacerbation risk during follow-up (incidence rate ratios [95% confidence interval]: 1.35 [1.29-1.42], 1.22 [1.15-1.29], and 1.26 [1.19-1.34] for 0-5-, 6-11-, and 12-17-year-olds, respectively); the association persisted with SABA as a continuous variable and was stronger among patients without atopic diseases (32%-44% increased risk versus. 14%-21% for those with atopic disease across groups).High SABA use was associated with increased asthma exacerbation risk in children, particularly in those without comorbid atopic diseases, emphasizing the need for asthma medication reviews and reformative initiatives by caregivers and healthcare providers on SABA use.

- BACKGROUND:Hyperglycaemia is associated with aggravated ischaemic brain injury. The main objective of this study was to investigate the effects on cerebral perfusion of 5 min of cardiac arrest during hyperglycaemia and normoglycaemia.METHODS:Twenty triple-breed pigs (weight: 22-29 kg) were randomised and clamped at blood glucose levels of 8.5-10 mM [high (H)] or 4-5.5 mM [normal (N)] and thereafter subjected to alternating current-induced 5 min-cardiac arrest followed by 8 min of cardiopulmonary resuscitation and direct current shock to restore spontaneous circulation.RESULTS:Haemodynamics, laser Doppler measurements and regional venous oxygen saturation (HbO2 ) were monitored, and biochemical markers in blood [S100β, interleukin (IL)-6 and tumour necrosis factor (TNF)] quantified throughout an observation period of 3 h. The haemodynamics and physiological measurements were similar in the two groups. S100β increased over the experiment in the H compared with the N group (P < 0.05). IL-6 and TNF levels increased across the experiment, but no differences were seen between the groups.CONCLUSIONS:The enhanced S100β response is compatible with increased cerebral injury by hyperglycaemic compared with normoglycaemic 5 min of cardiac arrest and resuscitation. The inflammatory cytokines were similar between groups.

- This co-creation study aimed to develop a smartphone self-test application for balance and leg strength in collaboration between older adults and the research team. The paper describes older participants' preferences for, and their contribution to, the application design. Technology to assess movements is available in smartphones with built-in sensors, and one of the challenges is to develop a valuable self-test for older adults. The participants contributed to the design of the application's instructions and user interface. Multiple data collection methods were used: user-test with Think aloud method, mock-ups, homework assignment as co-researcher, audio and video recordings. Qualitative content analysis with a deductive-inductive approach was used, guided by the Optimized Honeycomb model for user experience (UX) as a categorization matrix. The analysis resulted in 17 subcategories within the seven facets of the UX Honeycomb model (findable, accessible, usable, desirable, credible, useful, and valuable), and describes the older participants' preferences and experiences. The main results were participants' desire to know why, to get clear and appropriate information, and expectations of the self-test to be useful. It was feasible and valuable to develop the self-test application in co-creation with the intended user-group, in order to get direct feedback and suggestions for the development.

Digital fall prevention for older adults : Feasibility of a self-managed exercise application and development of a smartphone self-test for balance and leg strength
- 2021

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- As the numbers of older adults grow, fall prevention is vital to reduce health care needs due to falls and to increase quality of life. Balance and strength exercises have been found to be effective in fall prevention, however, long-term adherence is often poor. The growth of digital technology in society has generated opportunities for fall prevention with eHealth. The aim of this thesis was to evaluate the feasibility and use of a new digital fall prevention exercise programme, and to develop and investigate a smartphone self-test application for balance and leg strength. Three different studies included community-dwelling older adults ≥ 70 years, who were able to rise from a chair and stand without support. A feasibility study evaluated a new digital exercise programme (DP) compared to a paper booklet exercise programme (PB) for self-managed fall prevention in a four-month controlled participant preference trial (n = 67) (Paper I & II). Self-reported data on adherence, falls efficacy, and functional ability were collected and analysed, along with performance-based measures of gait speed, balance, and chair stand test. In Paper II the feasibility was explored of using the self-reported scales and performance-based outcome measures. A self-test application was also developed (Paper III) in co-creation with 10 participants, who met during five sessions to design the application’s instructions and user interface. The participants’ preference for and their contribution to the application design was analysed with qualitative content analysis with a deductive-inductive approach. A concurrent validity study (n = 31) (Paper IV) assessed the correlations between variables from the self-test prototype and outcome measures from clinical instruments. Results from the feasibility study show that 43% chose the DP and 57% PB, and the attrition rate was 17% and 37% respectively. Both groups had similar adherence, but for the subgroup that exercised most, participants in the DP group reported significantly more exercise time (Paper I). Participants in both groups reported a boost in balance after the intervention, and in the DP group also improved leg strength. Significantly more participants continued to use the DP at 12 months. The self-managed exercise intervention (Paper II) resulted in improvements in functional leg strength, which positively correlated with exercise time, but no other performance-based outcomes showed any significant improvements. Performance-based measurements of balance as well as the self- reported balance confidence and fear of falling revealed ceiling effects. Pre-assessments of self-reported outcomes and performance-based measures showed significant but low correlations, no such correlations were seen in change scores. The deductive-inductive analysis of the co-creation process resulted in 17 subcategories within the seven facets of the Optimized Honeycomb model for iii user experience (Paper III). The main results were that participants desired clear and appropriate information to understand why things were done in a certain way, and their contributions enhanced the user experience of the self-test. The concurrent validity testing of the self-test prototype (IV) showed low to moderate correlations for the strength test but limited correlations for the balance test. In conclusion the DP group showed comparable adherence to the programme as the PB group, as well as to previous studies, indicating it was feasible to use the new DP. DP participants also reported better exercise maintenance after 12 months. Positive self-reported effects were expressed in addition to leg strength improvement. Outcome measures for balance and falls efficacy revealed ceiling effects, consequently, these instruments might not be suitable for assessments in all community-dwelling older adults. In particular, for balance related outcomes there is a need for new more sensitive measurements. The co-creation of the smartphone self-test was feasible and valuable for user experience, but further validity and reliability testing are needed before it can serve as an independent assessment tool.

- The phylogeny of scale-worms, benthic polychaetes carrying dorsal scales (elytra), including taxa from Acoetidae, Aphroditidae, Eulepethidae, Pholoidae, Pholoididae, Polynoidae and Sigalionidae (Aphroditiformia), is assessed from the nuclear markers 18SrRNA and 28SrRNA, and mitochondrial 16SrRNA and cytochrome c oxidase subunit I (COI), and 24 morphological characters. The data sets are analyzed both separately and combined, with Bayesian analyses, maximum likelihood and parsimony. In total, 56 terminal taxa are examined, including 48 taxa from all scale-worm families, and eight out-group species. The results indicate that Aphroditidae and Eulepethidae are the most basally placed families among the scale-worms. The Pholoididae and Pisionidae are positioned within and synonymized with the Sigalionidae, and Pholoidae may be part of the same group. The subfamily Iphioninae falls out as sister group to a clade consisting of Polynoidae and Acoetidae and is elevated to Iphionidae. The families now included in the Aphroditiformia are Acoetidae, Aphroditidae, Eulepethidae, Pholoidae, Polynoidae, Iphionidae and Sigalionidae, and the subfamily name Harmothoinae and Acholoinae are treated as a junior synonyms of Polynoinae.

- Overuse of short-acting β2-agonists (SABA) may indicate poor asthma control and adverse health outcomes. Contemporary population-based data on use, risk factors and impact of SABA (over)use on asthma exacerbations and mortality are scarce, prompting initiation of the global SABINA (SABA use IN Asthma) programme.MethodsBy linking data from Swedish national registries, asthma patients aged 12–45 years with two or more collections of drugs for obstructive lung disease during 2006–2014 were included. SABA overuse was defined as collection of more than two SABA canisters in a 1-year baseline period following inclusion. SABA use was grouped into 3–5, 6–10 and ≥11 canisters per baseline-year. Cox regression was used to examine associations between SABA use and exacerbation (hospitalisations and/or oral corticosteroid claims) and mortality.ResultsThe analysis included 365 324 asthma patients (mean age 27.6 years; 55% female); average follow-up was 85.4 months. 30% overused SABA, with 21% collecting 3–5 canisters per year, 7% collecting 6–10 canisters per year and 2% collecting ≥11 canisters per year. Increasing number of collected SABA canisters was associated with increased risk of exacerbation, as follows. 3–5 canisters: hazard ratio (HR) 1.26 (95% CI 1.24–1.28); 6–10 canisters: 1.44 (1.41–1.46); and ≥11 canisters: 1.77 (1.72–1.83), compared to two or fewer canisters per year. Higher SABA use was associated with incrementally increased mortality risk (2564 deaths observed), as follows. 3–5 canisters: HR 1.26 (95% CI 1.14–1.39); 6–10 canisters 1.67 (1.49–1.87); and ≥11 canisters: 2.35 (2.02–2.72) compared to two or fewer canisters per year.ConclusionOne-third of asthma patients in Sweden collected three or more SABA canisters annually. SABA overuse was associated with increased risks of exacerbation and mortality. These findings emphasise that monitoring of SABA usage should be key in improving asthma management.
