- Objective. To investigate whether the effect of 48-month usage of coenzyme Q10 and selenium on cardiac function was different for participants with different levels of cardiac wall tension as measured by plasma levels of N-terminal natriuretic peptide (NT-proBNP) at baseline. Methods. A 48-month randomized double-blind controlled trial in a cohort of community-dwelling elderly (mean age 78 years) was carried out. A total of 443 participants were given coenzyme Q10 combined with selenium, or a placebo. NT-proBNP measured at baseline and 48 months was used to evaluate the cardiac wall tension. Results. After 48 months, supplementation of coenzyme Q10 and selenium had varying impacts depending on the severity of impairment of cardiac function. Analyses of the responses in the different quintiles of baseline NT-proBNP showed that those with active supplementation, and a plasma level of NT-proBNP in the second to fourth quintiles demonstrated significantly reduced NT-proBNP levels (p = 0.022) as well as cardiovascular mortality after 48 months (p = 0.006). Conclusion. Long-term supplementation of coenzyme Q10/selenium reduces NT-proBNP levels and cardiovascular mortality in those with baseline NT-proBNP in the second to fourth quintiles indicating those who gain from supplementation are patients with mild to moderate impaired cardiac function.

- The impact of supplementation with selenium and coenzyme Q10 (CoQ10) on health-care usage and health-related quality of life (Hr-QoL) in community-dwelling elderly people has, to our knowledge, not previously been investigated. To investigate the effect of 48 months supplementation with CoQ10 and selenium on community-dwelling elderly as regards: (I) the number of days out of hospital, and (II) the effect on Hr-QoL. A 48-month double-blind randomized placebo-controlled trial was carried out. A total of 443 participants were given CoQ10 and organic selenium yeast combined, or a placebo. All admissions to the Department of Internal Medicine or Cardiology were evaluated. Hr-QoL were measured with the Short Form-36 (SF-36), the Cardiac Health Profile (CHP) and one item overall-quality of life (overall-QoL). A total of 206 participants were evaluated after 48 months. No changes were found in the number of days out of hospital or Hr-QoL. A sub-analysis of participants matched for age, gender and baseline cardiac wall tension as measured by NT-proBNP was performed. The mean number of days out of hospital was 1779 for those taking the active substance compared to 1533 for those taking the placebo (p=0.03). Those with active substance declined significantly less in the HR-QoL domains of physical role performance (p=0.001), vitality (p=0.001), physical component score (p=0.001), overall QoL (p=0.001), somatic dimension (p=0.001), conative dimension (p=0.001) and global function (p=0.001). In a match-group analysis selenium and CoQ10 increased the number of days out of hospital and slowed the deterioration in Hr-QoL.

Konferensbidrag (refereegranskat)abstract
- Background: Over the last decades the RA-treatment strategies have changed considerably. Routines for early RA diagnosis and instituted disease modifying anti rheumatic drugs (DMARDs) have been established. In the early 2000s biologic agents also became available for treatment purposes. Despite these altered and improved strategies RA patients continue to report pain and activity limitations; women more so than men.Objectives: To study differences regarding pain and activity limitations during the first three years after diagnosis of RA in today's patients compared with patients diagnosed 10 years earlier from a gender perspective.Methods: This study was based on patients recruited to the project “early interventions in RA” (TIRA). In the first cohort (TIRA-1) 320 patients were included during 1996-1998. In the second cohort (TIRA-2) 463 patients were included during 2006-2008. Disease activity score 28 joint count (DAS-28) and medication were registered. Pain intensity (VAS), bodily pain (BP) in Short Form36 (SF-36) and activity limitation (Health Assessment Questionnaire, HAQ) were reported at inclusion and at follow-ups after one, two and three years.Results: Disease activity did not differ between cohorts at inclusion, but was significant lower at the follow ups in the TIRA-2 cohort compared with the TIRA-1 cohort. Patients in TIRA2 were prescribed traditional DMARD:s and biologic agents more frequent than in TIRA-1. The TIRA-2 patients reported significantly higher pain intensity and activity limitations at inclusion but lower pain intensity and activity limitations at all follow-ups than TIRA-1 patients. There were no significant differences between cohorts regarding bodily pain at inclusion, but thereafter the TIRA-2 patients showed significant lower bodily pain than the TIRA-1 patients. Men reported lower activity limitation than women in TIRA-1; otherwise there were no gender differences in TIRA-1. In TIRA-2, there were no significant gender differences regarding pain at inclusion. However, men reported lower pain than women at all follow-ups. Women, in turn, reported significantly higher activity limitations at all time points in TIRA-2. Pain and activity limitations were significantly reduced from inclusion to the one year follow-up but remained stable thereafter.Conclusions: Both women and men in today's early RA patient cohort report lower pain and less activity limitations at the follow ups after diagnosis of RA compared to 10 years earlier. However, both activity limitations and bodily pain are still pronounced.

- Objectives: To study differences regarding pain and activity limitations during the 3 years following diagnosis in women and men with contemporary treated early RA compared with their counterparts who were diagnosed 10 years earlier. Method: This study was based on patients recruited to the Early Intervention in RA (TIRA) project. In the first cohort (TIRA-1) 320 patients were included in time for diagnosis during 1996-1998 and 463 patients were included in the second cohort (TIRA-2) during 2006-2009. Disease activity, pain intensity (Visual Analogue Scale, VAS), bodily pain (BP) in the 36-item Short Form Health Survey (SF-36), activity limitations (Health Assessment Questionnaire, HAQ), and medication were reported at inclusion and at follow-up after 1, 2, and 3 years. Results: Disease activity, pain, and activity limitations were pronounced at inclusion across both genders and in both cohorts, with some improvement observed during the first year after diagnosis. Disease activity did not differ between cohorts at inclusion but was significantly lower at the follow-ups in the TIRA-2 cohort, in which the patients were prescribed traditional disease-modifying anti-rheumatic drugs (DMARDs) and biological agents more frequently. In TIRA-2, patients reported significantly lower pain and activity limitations at all follow-ups, with men reporting lower pain than women. Women reported significantly higher activity limitations at all time points in TIRA-2. Conclusions: Pain and activity limitations were still pronounced in the contemporary treated early RA cohort compared with their counterparts diagnosed 10 years earlier and both of these factors need to be addressed in clinical settings.

Tidskriftsartikel (refereegranskat)abstract
- The detection of antinuclear antibodies is central to the diagnosis and prognosis of systemic lupus erythematosus (SLE), primary Sjogrens syndrome (pSS) and mixed connective tissue disease (MCTD). Anti-U1-RNP and anti-RNP70 antibodies were assayed in the sera of patients with SLE (n = 114), pSS (n = 54) and MCTD (n = 12). In the SLE group, 34/114 (30%) were anti-U1-RNP positive, and 21/114 (18%) were both anti-RNP70 positive and anti-U1-RNP positive. In the MCTD group, 10/12 (83%) were anti-U1-RNP positive, and 9/12 (75%) were anti-RNP70 positive. Only one individual with pSS was antibody positive (for both anti-U1-RNP and anti-RNP70). All anti-RNP70-positive samples were also anti-U1-RNP positive. Anti-U1-RNP-positive subjects with SLE were younger (p < 0.0001); showed lower concentrations of complement protein 3 (p = 0.03); had lower eosinophil (p = 0.0005), lymphocyte (p = 0.006) and monocyte (p = 0.03) counts; and had accrued less organ damage (p = 0.006) than the anti-U1-RNP-negative SLE patients. However, we observed no significant clinical or laboratory parameter differences between the anti-U1-RNP-positive individuals with/without anti-RNP70 in the SLE group. In conclusion, anti-RNP70 antibodies are not exclusive to MCTD but are rarely detected in pSS and healthy individuals. In SLE, anti-U1-RNP antibodies are associated with a clinical phenotype that resembles MCTD, with hematologic involvement and less damage accrual. Based on our results, the clinical value of subtyping anti-RNP70 in anti-U1-RNP-positive sera appears to be of limited value.

- OBJECTIVES: To determine the health status of athletes before the start of an international athletics championship and to determine whether preparticipation risk factors predicted in-championship injuries.METHODS: At the beginning of the 2013 International Association of Athletics Federations (IAAF) World Championships, all registered athletes (n=1784) were invited to complete a preparticipation health questionnaire (PHQ) on health status during the month preceding the championships. New injuries that occurred at the championships were prospectively recorded.RESULTS: The PHQ was completed by 698 (39%) athletes; 204 (29.2%) reported an injury complaint during the month before the championships. The most common mode of onset of preparticipation injury complaints was gradual (43.6%). Forty-nine athletes in the study reported at least one injury during the championships. Athletes who reported a preparticipation injury complaint were at twofold increased risk for an in-championship injury (OR=2.09; 95% CI 1.16 to 3.77); p=0.014). Those who reported a preparticipation gradual-onset injury complaint were at an almost fourfold increased risk for an in-championship time-loss injury (OR=3.92; 95% CI 1.69 to 9.08); p=0.001). Importantly, the preparticipation injury complaint severity score was associated with the risk of sustaining an in-championship injury (OR=1.14; 95% CI 1.06 to 1.22); p=0.001).SUMMARY AND CONCLUSIONS: About one-third of the athletes participating in the study reported an injury complaint during the month before the championships, which represented a risk factor for sustaining an injury during the championship. This study emphasises the importance of the PHQ as a screening tool to identify athletes at risk of injuries before international championships.

Emotional Dysregulation and Trauma Symptoms Mediate the Relationship Between Childhood Abuse and Nonsuicidal Self-Injury in Adolescents
- 2022
-
Ingår i: Frontiers in Psychiatry. - : Frontiers Media SA. - 1664-0640. ; 13
-
Tidskriftsartikel (refereegranskat)abstract
- BackgroundNonsuicidal self-injury (NSSI) is common in adolescents. Emotion dysregulation has been identified as a core mechanism in the development and maintenance of NSSI and it is therefore an important target when addressing NSSI. The pathogenic connection between different kinds of childhood abuse, difficulties in emotion regulation and NSSI needs further investigation. The objective of this study was to examine whether difficulties with emotion regulation and trauma symptoms, separately and together, mediate the relationships between sexual, physical and emotional abuse and NSSI. MethodCross-sectional data was collected from 3,169 adolescent high-school students aged 16-19 years (M = 18.12, SD = 0.45). Data from self-reported experiences of childhood abuse, current difficulties with emotion regulation (measured with the Difficulties with Emotion Regulation Scale, DERS-16) and trauma symptoms (measured with the Trauma Symptom Checklist for Children, TSCC), and NSSI were collected. Structural Equation Modeling (SEM) was used to test the proposed relationships between variables. ResultsThe prevalence of life-time NSSI was 27.4%. Prevalence of reported childhood abuse was 9.2, 17.5, and 18.0% for sexual, physical, and emotional abuse, respectively. Childhood abuse, difficulties with emotion regulation and trauma symptoms exhibited significant positive associations with NSSI in adolescents. Emotional dysregulation and trauma symptoms were both found to mediate the relationship between childhood abuse and NSSI. Latent variable models were found to fit data well. ConclusionResults indicate that increased levels of emotional dysregulation and trauma symptoms in relation to childhood abuse contribute to the increased risk of NSSI. Further, results point to some aspects of emotional dysregulation and trauma symptoms being more important in this regard. Clinical implications are discussed.

Deaf signers and hearing non-signers recruit similar networks for arithmetic and phonological tasks
- 2013
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Profoundly deaf individuals sometimes have difficulty with arithmetic and phonological tasks. In the present study we investigate if these differences can be attributed to differences in recruitment of neurobiological networks. Seventeen hearing non-signers (HN) and sixteen deaf signers (DS) matched on age, gender and non-verbal intelligence took part in an fMRI study. In the scanner three digit/letter pairs were visually presented and the participants performed six different blocked tasks tapping processing of digit and letter order, multiplication, subtraction and phonological ability. Data were analysed using two 2x2x2 ANOVAs; process (arithmetic, language) x level (high, low) x group (DS, HN). A main effect of process revealed language networks in the left inferior frontal gryus, supramarginal gyrus, fusiform gyrus and insula. Arithmetic networks included left middle orbital gyrus and superior medial gyrus. A main effect of level revealed low level processing (digit/letter order) in the right middle occipital gyrus and the right precuneus and high level processing (subtraction/multiplication/phonological ability) in left inferior frontal gyrus. There was no main effect of group but a significant task x group interaction in the right temporal pole which in DS (but not HN) was activated more for arithmetic than language processing (pfwe = .022) when multiplication was included in the analysis. This region is implicated in conceptual representation. These results suggest that both arithmetic and language are processed similarly by DS and HN with possible between-group differences in the use of conceptual representation in arithmetic and language tasks.

Deaf signers use magnitude manipulatioin strategies for mulitplication : fMRI evidence
- 2014
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Evidence suggests that the lag reported in mathematics for deaf signers derives from difficulties related to the verbal system of number processing as described in the triple code model. For hearing individuals the verbal system has been shown to be recruited for both arithmetic and language tasks. In the present study we investigate for the first time neuronal representations of arithmetic in deaf signers. We examine if the neural network supporting arithmetic and language, including the horizontal portion of the intraparietal sulcus (HIPS), the superior parietal lobule (SPL) bilaterally, the left angular gyrus (AG), pars opercularis (POPE) and pars triangularis (PTRI) of the left inferior frontal gyrus (IFG), is differently recruited for deaf and hearing individuals. Imaging data were collected from 16 deaf signers and 16 well-matched hearing nonsigners, using the same stimulus material for all tasks, but with different cues. During multiplication, deaf signers recruited rHIPS more than hearing non-signers, suggesting greater involvement of magnitude manipulation processes related to the quantity system, whereas there was no evidence that the verbal system was recruited. Further, there was no support for the notion of a common representation of phonology for sign and speech as previously suggested.
