- AIM: To describe health status and psychological distress among in-hospital cardiac arrest (IHCA) survivors in relation to gender.METHODS: This national register study consists of data from follow-up registration of IHCA survivors 3-6 months post cardiac arrest (CA) in Sweden. A questionnaire was sent to the survivors, including measurements of health status (EQ-5D-5L) and psychological distress (HADS).RESULTS: Between 2013 and 2015, 594 IHCA survivors were included in the study. The median values for EQ-5D-5L index and EQ VAS among survivors were 0.78 (q1-q3=0.67-0.86) and 70 (q1-q3=50-80) respectively. The values were significantly lower (p<0.001) in women compared to men. In addition, women reported more problems than men in all dimensions of EQ-5D-5L, except self-care. A majority of the respondents reported no problems with anxiety (85.4%) and/or symptoms of depression (87.0%). Women reported significantly more problems with anxiety (p<0.001) and symptoms of depression (p<0.001) compared to men. Gender was significantly associated with poorer health status and more psychological distress. No interaction effects for gender and age were found.CONCLUSIONS: Although the majority of survivors reported acceptable health status and no psychological distress, a substantial proportion reported severe problems. Women reported worse health status and more psychological distress compared to men. Therefore, a higher proportion of women may be in need of support. Health care professionals should make efforts to identify health problems among survivors and offer individualised support when needed.

- Marine lipids contain a high proportion of polyunsaturated fatty acids (PUFA), including the characteristic long chain (LC) n-3 PUFA. Upon peroxidation these lipids generate reactive products, such as malondialdehyde (MDA), 4-hydroxy-2-hexenal (HHE) and 4-hydroxy-2-nonenal (HNE), which can form covalent adducts with biomolecules and thus are regarded as genotoxic and cytotoxic. PUFA peroxidation can occur both before and after ingestion. The aim of this study was to determine what levels of MDA, HHE and HNE can evolve in the gastric and intestinal lumen after ingesting meals containing fish or fish oil using a dynamic gastrointestinal (GI) model (TIM). The impact of the fish muscle matrix, lipid content, fish species, and oven baking on GI oxidation was evaluated. MDA and HHE concentrations in gastric lumen increased for all meals during digestion, with the highest level found with herring mince; similar to 25 mu M MDA and similar to 850 nM HHE. Aldehyde concentrations reached in intestinal lumen during digestion of fish containing meals were generally lower than in gastric lumen, while isolated herring oils (bulk and emulsified) generated higher MDA and HHE values in intestinal lumen compared to gastric lumen. Based on aldehyde levels in gastric lumen, meals containing herring lipids were ranked: raw herring (17% lipid) = baked herring (4% lipid) > raw herring (4% lipid) >> herring oil emulsion > herring oil. Herring developed higher concentrations of MDA and HHE during gastric digestion compared to salmon, which initially contained lower levels of oxidation products. Cooked salmon generated higher MDA concentrations during digestion than raw salmon. Low levels of HNE were observed during digestion of all test meals, in accordance with the low content of n-6 PUFA in fish lipids.

- Marine long-chain polyunsaturated fatty acids (LC n-3 PUFA) are associated with reduced risk for inflammatory diseases, such as cardiovascular diseases and rheumatoid arthritis. These fatty acids, however, are rapidly oxidized, generating highly reactive malondialdehyde (MDA), 4-hydroxy-2-hexenal (HHE) and 4-hydroxy-2-nonenal (HNE). These oxidation products may interact with DNA and proteins, thus possibly leading to impaired cell functions. Little is known about the formation of MDA, HHE and HNE in fish oil in the gastrointestinal (GI) tract. In this study, the effect of dynamic in vitro digestion of cod liver oil on the generation of MDA, HHE and HNE was evaluated using the TNO Gastro-Intestinal Model (tiny-TIM). Effects of pre-formed oxidation products, pre-emulsification of the oil, and addition of oxidants (EDTA and hemoglobin, Hb) on GI oxidation were evaluated. Formation of aldehydes occurred during GI digestion. However, only emulsified oil fortified with 11.5 μM Hb oxidized to a degree that overcame the dilution induced by gastric secretion, which caused increased aldehyde concentrations in gastric lumen up to 90 min. The maximum levels of aldehydes generated in this study were 24.5 μM MDA, 1.6 μM HHE and 0.07 μM HNE. Oils containing different amounts of pre-formed lipid oxidation products maintained the same oxidation ranking order during digestion, even though the relative changes were not directly proportional. Emulsification of the oil had an unclear effect in the gastric phase, but a pro-oxidative effect in the intestinal phase. In general, higher aldehyde levels were reached in the intestinal lumen than in the initial meal, demonstrating that GI digestion promotes oxidation. Hence, epithelial cells may be exposed to elevated amounts of reactive aldehydes for several hours after a meal containing fish oil.

- The periwinkle Littorina saxatilis has repeatedly evolved both a small, fragile and globose "wave ecotype" confined to wave-swept shores and a large, robust and elongated "crab ecotype" found in nearby crab-rich but less-exposed shores. This phenotypic divergence is assumed to reflect, in some part, local adaptation to wave exposure, but this hypothesis has received incomplete experimental testing. Here, we report a test of the prediction that the wave ecotype has a higher capacity to resist water flow than the crab ecotype. We sampled snails along a crab-wave transect and measured their resistance to dislodgement in a high-speed water flume with water speeds that match those of breaking waves in a range of relevant field conditions. Snails from the wave environment were consistently more resistant to water flow than snails from the crab environment and high resistance was positively correlated with the surface area of the foot and the area of the outer aperture contour both relative to shell size, and to the extent of lateral shell compression. In a separate experiment, we found that snails raised in still water in a common garden showed higher resistance to water flow if originating from a wave environment than from a crab environment, and this was true both at juvenile (2 weeks) and adult (10 months) developmental stages. This result suggests genetic control of a distinct "wave adapted" phenotype, likely to be maintained under strong divergent selection between the two adjacent habitats.

- Objective: To describe treatment patterns in the Swedish early psoriatic arthritis cohort (SwePsA) of the mono-/oligo-arthritic (M/O) and polyarthritis (P) and identify early predictive factors for treatment with disease-modifying anti-rheumatic (DMARD), non-steroidal anti-inflammatory drugs (NSAID), and tumour necrosis factor inhibition (TNFi) after 5 years.Methods: Data for 198 M/O and P PsA were obtained within the programme for SwePsA. Multinomial and binary logistic regression analyses were used to assess the association between early predictive factors and treatment after 5 years adjusted for age at inclusion. The analysis of DMARD/NSAID was adjusted for medication at inclusion.Results: After inclusion visit, DMARD was prescribed in 30% of M/O and 56% of P PsA; mainly methotrexate. TNFi was not prescribed at inclusion, but 23 patients were treated at 5-year follow-up. The adjusted OR (95% CI) for treatment with both DMARD and NSAID after 5 years was 3.65 (1.34 - 9.89) (p=0.010) for Disease Activity Score 28 (DAS28) >3.2 and 2.90 (1.20-6.99) (p=0.038) for Disease Activity Index in Psoriatic Arthritis (DAPSA) >14 at inclusion. TNFi treatment was, after adjusting for age, associated with high erythrocyte sedimentation rate (p=0.0043), high C-reactive protein (p=0.013), DAPSA (p<0.001), not reaching minimal disease activity (p=0.001) high health assessment questionnaire (p=0.001), patient's overall assessment on the visual analogue scale (VAS) (p=0.009), high pain VAS (p=0.007), and high number of tender and swollen joints (p=0.031) at inclusion.Conclusion: Disease activity in early M/O and P PsA is to be considered in deciding the level of health care assessment and future pharmacological treatment. DAS28 >3.2 and DAPSA>14 early in the disease predict subsequent treatment with DMARD. For prediction of biological treatment, not reaching MDA at onset of disease, would be the composite index of choice.

- Disability organisations have not been engaged in the debate about the International Classification of Functioning, Disability and Health (ICF) in Sweden. We wanted to know representatives’ attitudes about the ICF. The aim of the study was to elucidate the arguments for and against the ICF among representatives of disability organisations. The study consisted of eighteen representatives (from six disability organisations) that answered electronic questionnaires. The questionnaires involved ten open questions about the arguments for and against the ICF. The answers of the questionnaires have been categorized according to qualitative content analysis. Our results indicated four themes: awareness, arguments for and against, influence and the future. More than half of the representatives had very limited awareness of the ICF. There was an explicit criticism of individual classification but more positive comments about classification on an aggregated level. The most important issue for representatives was influencing social policy in society, not learning and spreading information about the ICF.
