Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Dödsfall till följd av hjärtstopp av kardiella orsaker, s k plötslig hjärtdöd, hos unga och inom idrotten skiljer sig på flera sätt från plötslig hjärtdöd i högre åldrar. Drabbade kan sakna symtom, men de har vanligen en bakomliggande, ofta okänd, hjärtsjukdom. Flera olika hjärtsjukdomar har visats kunna ligga bakom plötsligt hjärtstopp bland unga och inom idrotten. Vanligen är de ärftliga och svårdiagnostiserade. Idrottande unga löper större risk att drabbas av plötsligt hjärtstopp än icke-idrottande. Screening av tävlingsidrottare rekommenderas internationellt, i Sverige också av Socialstyrelsen och Riksidrottsförbundet, för riskgrupper som elitidrottare från 16 års ålder. Vid hjärtstopp är tidig insats avgörande för utfallet. Det är därför viktigt att adekvat beredskap och kompetens finns på plats vid idrottsevenemang.

Morale in very old people : With focus on stroke, depression and survival
- 2015

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Morale is a multidimensional concept, often defined as a future-oriented optimism or pessimism regarding the problems and opportunities associated with ageing. Very old people, older than 80 years, constitute an age group that is expected to increase in Europe from 4.7% of the general population today to 12.0% in the year 2060 in Europe. The overall aim of this thesis was to explore morale among very old people.Method: The Umeå 85+/GErontological Regional Database study (GERDA) is a population-based study carried out in parts of northern Sweden and western Finland in which every second 85 year old, every 90 year old and everyone aged 95 years and older were invited to participate. The study started the year 2000 and every five years re-invites previous participants and invites new individuals to participate in the study. The Philadelphia Geriatric Center Morale Scale (PGCMS), which is widely used to measure morale in old people, has been translated into many languages.Results: There were 598 individuals who answered the PGCMS in the Umeå 85+/GERDA study. Despite respondents’ advanced age 92.6% (554/598) answered 16 or 17 of the questions. The construct validity of the Swedish version of the PGCMS was tested among the 493 individuals who answered all 17 questions using confirmatory factor analysis and the analysis showed a generally a good fit. Reliability tested with Cronbach’s alpha was 0.74. Reliability was also tested in a convenience sample of 54 individuals (mean age of 84.7±6.7 years) and the IntraClass Correlation coefficient (ICC) was 0.89.Almost 20% (91/465) of participants who could answer the PGCMS had had a stroke. Those with stroke had significantly lower PGCMS scores than those without (10.9±3.8 vs 12.1±3.0, p-value 0.008), but there were 38.5% with stroke history who had high morale. A multiple linear regression analysis showed that depression, angina pectoris and impaired hearing were independently associated with low morale among those with a stroke history.A logistic regression model showed that each point increase in PGCMS score lowered the risk of depressive disorders five years later (odds ratio 0.779, p<0.001, with each point increase in PGCMS). In a Cox model adjusted for several demographic, health- and function-related confounders, including age and gender, mortality was higher among participants with low morale (RR=1.36, p=0.032) than those with high morale. There was a similar but non-significant pattern towards increased mortality in participants with moderate morale compared to high morale (RR=1.21, p-value=0.136).Conclusion: The feasibility and psychometric properties of the Swedish version of the PGCMS seems to be satisfactory among very old people. A large proportion of very old people have had a stroke, which is associated with reduced morale. Depression, angina pectoris and impaired hearing were independently associated with low morale among those with stroke. Among very old people, a higher level of morale seems to be associated with a lower risk of suffering from depressive disorders five years later. High morale is independently associated with increased five-year survival among very old people.

Sudden cardiac death among the young in Sweden 1992-1999 : from epidemiology to support of the bereaved
- 2005

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Sudden cardiac death (SCD) in a young person is a rare but tragic event, and the potential of prevention is unknown. The aim of this thesis is to contribute to the prevention by analysing SCD in the young in Sweden during the period 1992-1999. Data of SCD in the young based on a national registry is not previously reported. The approach is broad, covering the spectrum from epidemiology to supportive needs of families confronted with SCD. The survey methods comprised analyses of national registries, questionnaires, personal interviews, forensic-, police-, medical- and military conscription records. The SCD group selected from the database of the National Board of forensic Medicine consisted of 181 persons, 15 to 35 years old, who had suffered an SCD during 1992-1999 in Sweden, 132 men (73 %) and 49 women (27 %). The mean incidence was 0.93 per 100,000 per year. The trend showed no decrease during the surveyed years, 1992-1999. The most common diagnoses were the structurally normal heart (21 %), coronary artery disease (18 %), and dilated cardiomyopathy (12 %). In a study group of 162 individuals (19 cases of aortic aneurysm, 17 men and two women, were excluded), ECGs, symptoms and lifestyle factors were analysed and related to the autopsy findings. ECGs were available in 66 individuals (59 men and seven women) and 50 % of these were pathological. The most frequent aberrations were repolarisation abnormalities and in half of the cases with more than one ECG a development in a pathological direction was seen. In four out of ten seeking medical advice because of symptoms an ECG was taken and three of these were pathological. Possibly cardiac-related alpitations were common, but also non-specific symptoms such as fatigue after an influenza- like illness. It was not possible to link a certain sign or symptom to a specific diagnosis. In 26 (16 %) there was a family history of SCD. Physical activity and body mass index (BMI) in men were the same as in a control group, whilst women had a higher BMI and a lower level of physical activity than the controls. In coronary artery disease deaths there were a high percentage of smokers and BMI was higher than in the controls in both sexes. Competing athletes more often died during physical activity than non-athletes, but were not overrepresented in the SCD group. The majority of the athletes who died during physical activity had an underlying structural cardiac disease. Death during sleep was the most common mode of death in subjects with structurally normal heart. A lack of supportive structures in the handling of bereaved relatives were disclosed in the interviews. Most participants felt that they had been left mainly to themselves to find information and support. A common reflection from the bereaved was that there is a need of the same supportive routines in cases of a single death as in accidents where there are several casualties. The bereaved had a need of getting an explanation and a need of supportive structures. The cognitive dimension of understanding and the emotional dimension of being understood were found to be significant for the complex processes of mourning and recreating one’s life as a bereaved. In summary, SCD was uncommon in the young, but the incidence was not decreasing during the study period. The most common autopsy findings were the structurally normal heart and coronary artery disease. Symptoms preceding SCD were common but often misinterpreted. The SCD group was very similar to the normal population with regard to life style factors. In certain cardiac disorders physical activity seemed to trigger sudden death, whilst in others death during sleep was the most common mode of death. There is no single test which predicts if a person is at risk of SCD. A further cardiac evaluation in cases with pathological ECGs, and in cases with a positive family history or serious unexplained symptoms such as syncope, might permit the early identification of persons at risk of SCD. ECG is an underused tool in the investigation of symptoms, and a database with old ECGs available for comparison could be useful in the prevention of SCD. There is a need of better care of the bereaved, and based on our findings we propose the introduction of a supportive program.
