- Background: A majority of adults with congenital heart disease (CHD) have reduced exercise capacity and do not reach the recommended level of physical activity. A physically active lifestyle is essential to maintain health and counteract acquired cardiovascular disease. This study illuminates aspects that may be relevant for performing physical activity.Purpose: To describe facilitators and barriers for physical activity in adults with CHD.Methods: Semi-structured interviews were performed individually with fourteen adults (age 19–68 years, women=7) with complex CHD. The interviews were analyzed using qualitative content analysis.Results: Aspects that may enable or inhibit physical activity were found in two domains; Facilitators and Barriers, which both consisted of four categories physical, psychological, psychosocial and environmental aspects (Table 1).

- Androgens exert important effects both in androgen-responsive tissues and in the intestinal tract. To determine the impact of the gut microbiota (GM) on intestinal androgen metabolism, we measured unconjugated (free) and glucuronidated androgen levels in intestinal contents from the small intestine, with a low bacterial density, and from cecum and colon, with a high bacterial density. Using a specific, sensitive gas chromatography-tandem mass spectrometry method, we detected high levels of glucuronidated testosterone (T) and dihydrotestosterone (DHT) in small intestinal content of mice of both sexes, whereas in the distal intestine we observed remarkably high levels of free DHT, exceeding serum levels by >20-fold. Similarly, in young adult men high levels of unconjugated DHT, >70-fold higher than in serum, were detected in feces. In contrast to mice with a normal GM composition, germ-free mice had high levels of glucuronidated T and DHT, but very low free DHT levels, in the distal intestine. These findings demonstrate that the GM is involved in intestinal metabolism and deglucuronidation of DHT and T, resulting in extremely high free levels of the most potent androgen, DHT, in the colonic content of young and healthy mice and men.

- AIMS: Assessment of ECG-features as predictors of sudden death in adults with hypertrophic cardiomyopathy (HCM).METHODS AND RESULTS: ECG-amplitude sums were measured in 44 normals, 34 athletes, a hospital-cohort of 87 HCM-patients, and 29 HCM-patients with sudden death or cardiac arrest (HCM-CA). HCM-patients with sudden death or cardiac arrest had substantially higher ECG-amplitudes than the HCM-cohort for limb-lead and 12-lead QRS-amplitude sums, and amplitude-duration products (P = 0.00003-P = 0.000002). Separation of HCM-CA from the HCM-cohort is obtained by limb-lead QRS-amplitude sum >or=7.7 mV (odds ratio 18.8, sensitivity 87%, negative predictive value (NPV) 94%, P < 0.0001), 12-lead amplitude-duration product >or=2.2 mV s (odds ratio 31.0, sensitivity 92%, NPV 97%, P < 0.0001), and limb-lead amplitude-duration product >or=0.70 mV s (odds ratio 31.5, sensitivity 93%, NPV 96%, P < 0.0001). Sensitivity in HCM-patients <40 years is 90, 100, and 100% for those ECG-variables, respectively. Qualitative analysis showed correlation with cardiac arrest for pathological T-wave-inversion (P = 0.0003), ST-depression (P = 0.0010), and dominant S-wave in V(4) (P = 0.0048). A risk score is proposed; a score >or=6 gives a sensitivity of 85% but a higher positive predictive value than above measures. Optimal separation between HCM-CA <40 years and athletes is obtained by a risk score >or=6 (odds ratio 345, sensitivity 85%, specificity 100%, P < 0.0001).CONCLUSION: Twelve-lead ECG is a powerful instrument for risk-stratification in HCM.

Tidskriftsartikel (refereegranskat)abstract
- The Christian Church, which-due to its message of God's grace towards all mankind-should be expected to lead the way in matters of humanity, seems to be stuck in a notion of normalcy; the kind of participation known by the church usually aims at a practice involving activities that require capacities not present among persons with severe disabilities. This study is about persons with intellectual disability and their experiences of participation in the Church of Sweden. The first section discusses the concept of participation. The second section is about participation and normalcy in the Church of Sweden and includes the stories of Eric, Unni, and David who all have an intellectual disability and want to belong to the People of the Faith.

A new chemiluminescence paradox: selective inhibition of isoluminol-amplified activity in phagocytes by peptides from annexin AI.
- 2008

Tidskriftsartikel (refereegranskat)abstract
- Chemiluminescence systems enhanced by either isoluminol or luminol in combination with a peroxidase are sensitive methods for the detection of reactive oxygen species (ROS) generated by phagocyte NADPH oxidase. The two amplifying substrates are structurally very similar, differing only in the position of the amino group in the aromatic ring of the molecules. This difference renders isoluminol a less lipophilic molecule that is less permeable to biological membranes. The use of isoluminol is consequently restricted to studies dealing with the secretion of oxygen metabolites. In this study we show that synthetic peptides derived from the N-terminal domain of the calcium-regulated protein annexin AI interfere with the detection of radicals in an isoluminol-amplified, but not in a luminol-amplified, system. The annexin AI-derived peptides reduce the light output with isoluminol excited by superoxide and horseradish peroxidase (HRP) in formyl-methionyl-leucyl-phenylalanine- and phorbol myristate acetate-stimulated cells, as well as by hydrogen peroxide and HRP. The precise mechanism for the inhibition is not known. The results presented strongly suggest that a reduced cellular response detected with isoluminol-amplified chemiluminescence should be confirmed with an alternative technique to determine release of superoxide anions and hydrogen peroxide.

- Aims To evaluate long-term all-cause risk of mortality in women and men hospitalized for the first time with atrial fibrillation (AF) compared with matched controls. Methods and results A total of 272 186 patients (44% women) <= 85 years at the time of hospitalization with incidental AF 1995-2008 and 544 344 matched controls free of in-hospital diagnosis of AF were identified. Patients were followed via record linkage of the Swedish National Patient Registry and the Cause of Death Registry. Using Cox regression models, the long-term relative all-cause mortality risk, adjusted for concomitant diseases, in women vs. controls was 2.15, 1.72, and 1.44 (P < 0.001) in the age categories <= 65, 65-74, and 75-85 years, respectively. The corresponding figures for men were 1.76, 1.36, and 1.24 (P < 0.001). Among concomitant diseases, neoplasm, chronic renal failure, and chronic obstructive pulmonary disease contributed most to the increased all-cause mortality vs. controls. In patients with AF as the primary diagnosis, the relative risk of mortality was 1.63, 1.46, and 1.28 (P < 0.001) in women and 1.45, 1.17, and 1.10 (P < 0.001) in men. Conclusion Atrial fibrillation was an independent risk factor of all-cause mortality in patients with incident AF. The concomitant diseases that contributed most were found outside the thromboembolic risk scores. The highest relative risk of mortality was seen in women and in the youngest patients compared with controls, and the differences between genders in each age category were statistically significant.

Tidskriftsartikel (refereegranskat)abstract
- Background: Many adults with congenital heart disease (CHD) have reduced aerobic exercise capacity and impaired muscle function. However, it is largely unknown which factors have influence on the confidence to perform exercise training, i.e. Exercise Self-Efficacy (ESE).Aims: To identify factors related to low ESE, and thus identify potential targets for rehabilitation and thereby enhance the potential for being physically active.Methods: Seventy-nine adults with CHD; simple lesions n=38 (women n=16), complex lesions n=41 (women n=17) (mean age 36.7±14.6 years) and 42 age and sex matched controls were recruited. All participants completed questionnaires on ESE, quality of life (EQ-5D), and physical activity (international physical activity questionnaire, IPAQ), and performed muscle endurance tests.Results: ESE was categorised into low (<26 points, n=24) and high (≥26 points, n=55). Patients with low ESE were older (45.2±15.4 vs. 32.6±12.5 years, p=0.002), more often had prescribed medication (67% vs. 44%, p=0.06), higher New York Heart Association functional class (NYHA) (≥ III) (25% vs. 7%, p=0.03) and performed fewer shoulder flexions (30.9±16.1 vs. 45.9±23.9, p=0.01) compared with those with high ESE. In the high ESE group, ESE did not differ from controls (33.8±3.9 vs. 33.4±6.1, p=0.74). In linear multivariate analysis age (B;-0.18, 95% CI -0.28- -0.08), smoking (B;-3.73, 95% CI -7.17- -0.28), EQ-5Dindex <1 (B;-3.33, 95% CI -6.08- -0.57) and number of shoulder flexions (B; 0.09, 95% CI 0.03–0.16) were independently associated with ESE.Conclusion: Many adults with CHD have low ESE. Rehabilitation targeting quality of life, smoking cessation and muscle training may improve ESE, and thus enhance the potential for being physically active in this population.

Tidskriftsartikel (refereegranskat)abstract
- Background: The New York Heart Association (NYHA) classification is applied in a wide spectrum of heart diseases including adult patients with congenital heart disease (ACHD). The NYHA-class assessment is often based on the evaluation by the caregiver, but to what extent it correlates with the patient's view of their function is not fully known.Purpose: To investigate the relation between the patient's self-reported physical limitations, symptoms, other heart defect related factors and NYHA-class assessed by the caregiver.Methods: Eligible patients (n=333, age 39.2±13.6 years) were identified and randomly selected from the national registry for CHD. All of the patients completed a standardized questionnaire measuring different PRO-domains. By combing self-reported data with registry data including NYHA-class, analyses of agreement of physical limitations were performed.Results: Almost 30% of the patients rated their limitations higher compared to the NYHA-class estimated by the caregiver. Patients with self-reported limitations and their NYHA-class underestimated by caregivers, more often reported symptoms, anxiety, lower health and worked fewer hours/week compared to other patients with CHD. There were no differences regarding sex, type of symptoms, prescribed medications, or complexity of cardiac lesion. In patients without self-reported limitations agreement with NYHA-class estimated by caregivers was 97%.Conclusion: Adult patients with CHD and self-reported limitations may not be correctly identified by the care-giver. Instruments for patient reported outcomes might improve the assessment of physical limitations and could further improve the correctness in evaluating the patient's status.

- Only few studies have been devoted to the actions of the renin-angiotensin system (RAS) in the human gastrointestinal tract. The present study was undertaken to elucidate the expression and action of RAS in the human esophageal mucosa. Mucosal specimens with normal histological appearance were obtained from healthy subjects undergoing endoscopy and from patients undergoing esophagectomy due to neoplasm. Gene and protein expressions of angiotensin II (Ang II) receptor type 1 (AT(1)) and type 2 (AT(2)) and angiotensin-converting enzyme (ACE) were analyzed. In vivo functionality in healthy volunteers was reflected by assessing transmucosal potential difference (PD). Ussing chamber technique was used to analyze the different effects of Ang II on its AT(1) and AT(2) receptors. Immunoreactivity to AT(1) and AT(2) was localized to stratum superficiale and spinosum in the epithelium. ACE, AT(1), and AT(2) were found in blood vessel walls. Transmucosal PD in vivo increased following administration of the AT(1) receptor antagonist candesartan. In Ussing preparations mean basal transmural PD was -6.4 mV, epithelial current (I(ep)) 34 muA/cm(2), and epithelial resistance (R(ep)) 321 Omega.cm(2). Serosal exposure to Ang II increased PD as a result of increased I(ep), whereas R(ep) was constant. Ang II given together with the selective AT(1)-receptor antagonist losartan, or AT(2) agonist C21 given alone, resulted in a similar effect. Ang II given in presence of the AT(2)-receptor antagonist PD123319 did not influence PD, but I(ep) decreased and R(ep) increased. In conclusion, Ang II receptors and ACE are expressed in the human esophageal epithelium. The results suggest that AT(2)-receptor stimulation increases epithelial ion transport, whereas the AT(1) receptor inhibits ion transport and increases R(ep).

Acute ethanol exposure elevates muscarinic tone in the septohippocampal system.

Tidskriftsartikel (refereegranskat)abstract
- The septohippocampal system has been implicated in the cognitive deficits associated with ethanol consumption, but the cellular basis of ethanol action awaits full elucidation. In the MS/DB, a muscarinic tone, reflective of firing activity of resident cholinergic neurons, regulates that of their non-cholinergic, putatively GABAergic, counterparts. Here we tested the hypothesis that ethanol alters this muscarinic tone. The spontaneous firing activity of cholinergic and non-cholinergic MS/DB neurons were monitored in acute MS/DB slices from C57Bl/6 mice. Exposing the entire slice to ethanol increased firing in both cholinergic and non-cholinergic neurons. However, applying ethanol focally to individual MS/DB neurons increased firing only in cholinergic neurons. The differential outcome suggested different mechanisms of ethanol action on cholinergic and non-cholinergic neurons. Indeed, with bath-perfused ethanol, the muscarinic antagonist methyl scopolamine prevented the increase in firing in non-cholinergic, but not cholinergic, MS/DB neurons. Thus, the effect on non-cholinergic neuronal firing was secondary to ethanol's direct action of acutely increasing muscarinic tone. We propose that the acute ethanol-induced elevation of muscarinic tone in the MS/DB contributes to the altered net flow of neuronal activity in the septohippocampal system that underlies compromised cognitive function.
