Forskningsöversikt (refereegranskat)abstract
- Aims. Evaluation of bariatric surgery as secondary prevention in obese patients with ischemic heart disease (IHD). Methods. Analysis of data from 4047 subjects in the Swedish Obese Subjects (SOSs) study. Thirty-five patients with IHD are treated with bariatric surgery (n = 21) or conventional treatment (n = 14). Mean follow-up is 10.8 years. Results. Bariatric surgery resulted in sustained weight loss during the study period. After 2 years, the surgery group displayed significant reductions in cardiovascular risk factors, relief from cardiorespiratory symptoms, increments in physical activity, and improved quality of life. After 10 years, recovery from hypertension, diabetes, physical inactivity, and depression was still more common in the surgery group. There were no signs of increased cardiovascular morbidity or mortality in the surgery group. Conclusion. Bariatric surgery appears to be a safe and feasible treatment to achieve long-term weight loss and improvement in cardiovascular risk factors, symptoms, and quality of life in obese subjects with IHD.

- Context: Cell death-inducing DFFA-like effector A (CIDEA) could be a potential target for the treatment of obesity via the modulation of metabolic rate, based on the findings that CIDEA inhibits the brown adipose tissue uncoupling process in rodents. Objective: To investigate the putative link between CIDEA and basal metabolic rate in humans, and to further elucidate the role of CIDEA in human obesity. Design: We have explored CIDEA gene expression in adipose tissue in two different human studies: A cross-sectional and population-based study assessing body composition and metabolic rate (Mölndal Metabolic study, n=92), and a longitudinal intervention-study of obese subjects treated with a very low calorie diet (VLCD study, n=24). Results: The CIDEA gene was predominantly expressed in adipocytes as compared to other human tissues. CIDEA gene expression in adipose tissue was inversely associated with basal metabolic rate independently of body composition, age and gender (p=0.014). VLCD induced an increase in adipose tissue CIDEA expression (p<0.0001) with a subsequent decrease in response to refeeding (p<0.0001). Reduced CIDEA gene expression was associated with a high body fat content (p<0.0001) and with high insulin levels (p<0.01). No dysregulation of CIDEA expression was observed in individuals with the metabolic syndrome when compared with BMI-matched controls. In a separate sample of VLCD-treated subjects (n=10), uncoupling protein 1 expression was reduced during diet (p=0.0026) and inversely associated with CIDEA expression (p=0.0014). Conclusion: The findings are consistent with the concept that CIDEA plays a role in adipose tissue energy expenditure.

Patients’ and Spouses’ Perspectives on Coronary Heart Disease and its Treatment
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Lifestyle changes and drug treatment can improve the prognosis and quality of life for patients with coronary heart disease (CHD), but their co-operation with suggested treatment is often limited. The aim of this thesis was to study how patients and their spouses conceive CHD and its treatment.Material and Methods: The research design used was inductive and descriptive. The studies were based on three complementary sets of data. Patients with CHD (n=23) and spouses (n=25) were interviewed one year after an episode of the disease. Consecutive patients with CHD derived from another investigation were interviewed within six weeks or one year after the coronary event (n=113). All semi-structured interviews, tape-recorded or from notes taken by hand, were subjected to analysis within the phenomenographic framework.Findings: The patients’ conceptions of CHD varied and were vague, even as judged on a lay level. They were associated with symptoms rather than with the disease. Co-operation with drug treatment was rarely linked to improved prognosis. The patients’ descriptions of benefits from lifestyle changes and treatment did not give the impression of being based on a solid understanding of the importance of such changes. Incentives for lifestyle changes were classified into four categories, all of which contained both facilitating and constraining incentives. Somatic incentives featured direct and indirect physical signals. Social/practical incentives involved shared concerns, changed conditions, and factors connected with external environment. Cognitive incentives were characterised by active decisions and appropriated knowledge, but also by passive compliance with limited insights, and by the creating of routines. Affective incentives comprised fear and reluctance related to lifestyle changes and disease and also lessened self-esteem. All incentives mostly functioned facilitatively. The cognitive and the social/practical incentives were the most prevalent.Spouses’ understanding about the causes of CHD involved both appropriate conceptions and misconceptions. Drug treatment was considered necessary for the heart, but harmful to other organs. Spouses’ support to partners was categorised, and found to be contextually bound. The participative role was co-operative and empathetic. The regulative role controlled and demanded certain behaviours. The observational role was passive, compliant, and empathetic. The incapacitated role was empathetic, unable to support, and positive to changes. The dissociative role was negative to changes and reluctant to be involved in lifestyle changes.Conclusions: These results could be useful in the planning of care and education for CHD patients. The findings also emphasise the importance of adopting a family perspective to meet the complex needs of these patients and their spouses in order to facilitate appropriate lifestyle changes.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Body mass index (BMI) is the dominating weight-for-height index, but its validity as a body fat (BF) index has not been properly examined. OBJECTIVES: Our aims were to establish and validate optimal weight-for-height indexes for predicting absolute and relative (percentage) amounts of BF, to examine whether other commonly available anthropometric variables or age could add to the predictive power, and to explore the upper limit for percentage BF. DESIGN: One thousand one hundred twelve randomly selected subjects, and an additional 149 obese subjects, were included in the study. The subjects were randomly allocated to either a primary study group or a validation group. BF was measured with dual-energy X-ray absorptiometry. The relations between weight/heightx (W/Hx) and BF (absolute or percentage) were examined for values of the exponent x that ranged from 0.0 to 3.0. The predictive power of equations that were based on optimal weight-for-height indexes was compared with equations based on weight, height, other anthropometric variables, and age. RESULTS: Absolute BF was optimally and linearly predicted by W/H1, whereas the percentage BF was optimally and nonlinearly predicted by W/H2. The percentage BF asymptotically approached 52% in women and 56% in men. The percentage BF increased only marginally from BMI (in kg/m2) values of >35 in women and >60 in men. Predictions of absolute BF were associated with smaller errors (8.5% for men and 5.7% for women) than were predictions of percentage BF (8.7% for men and 7.9% for women). The addition of other anthropometric measurements for both men and women, and the addition of age for women only, in the regression analyses moderately reduced these errors. CONCLUSION: Our data suggest that W/H may be a more optimal weight-for-height index than is BMI, particularly at high body weights.

Experiences of abandonment and anonymity among arthroplastic surgery patients in the perioperative period : some issues concerning communication, pain and suffering
- 2005

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Det övergripande syftet med avhandlingsarbetet är att illustrera och belysa upplevelsen av att vara patient med behov av ledprotes, avseende aspekterna kommunikation, smärtupplevelse, lidande och tillfredsställelse med vård och behandling. Under väntetiden för ledprotesoperation upplever deltagarna i studierna lidande i olika former, tillika att vården är otillgänglig och onåbar i ett ansiktslöst system (I). Att få information om sin sjukdom vad man kan/får/ska göra är nästan omöjligt. Kontakten med sjukvården är svår att upprätta och det är mestadels patientens ansvar att söka information om vad som händer (II). Den bristfälliga kommunikationen som deltagarna i delstudie I upplever, leder till att de känner sig missförstådda och nedvärderade av sjukvårdssystemet, och därmed befinner sig i en ständig kamp för att få sitt vårdbehov bekräftat. Under deltagarnas vandring i sjukvårdssystemet förändras deras negativa uppfattning om vården till att bli mer positiv när en reell kommunikation och personlig kontakt etablerats (IIV). Fynden i arbetena (I-IV) tolkas inom ramen för Katie Erikssons och Lennart Fredrikssons beskrivningar av lidande och det vårdande samtalet. En del deltagare i studierna har av egen kraft, eller till följd av personliga egenskaper uppnått insikter om sig själva och försonats med sitt lidande, på så sätt har de kunnat bibehålla eller uppnå mening i sin tillvaro. Av egen kraft, eller med hjälp av anhöriga kan individerna få sitt lidande bekräftat och därmed möjligheten att kunna lida ut och försonas med sig själv och den förändrade tillvaron. Så länge som sjukvården upplevs som ett ansiktslöst system finns det deltagare i avhandlingen som inte klarar av att ta itu med sitt lidande. Under patientens vandring i sjukvårdssystemet blir det uppenbart att systemet får ett ansikte först när deltagarna kan relatera till vården i form av en reell person. Vården får inte ett ansikte så länge som patienten upplever sig dåligt bemött utan detta sker när det med Fredrikssons termer uppstår ett vårdande samtal. Under väntetiden för operation finns det relativt få tillfällen där ett vårdande samtal har möjlighet att uppstå. Möjligheten för detta är dock större när patienten väl är inlagd på sjukhuset för att bli opererad, vilket återspeglas i den höga grad av tillfredsställelse med vården som uttrycks i delstudie II-IV. Patienterna är tillfredsställda med vård och behandling, trots att de har upplevt postoperativ smärta i en hög grad. I delstudie III var det 68% (n=40) och i delstudie IV 83.5% (n=50) som hade upplevt smärtor motsvarande ≥ 4 på Visuell Analog Skala (VAS). Under sjukhusvistelsen upplever sig patienten bekräftad och synlig i systemet. Synligheten är ömsesidig då även vården (systemet) får ett ansikte på patienten. I ett vårdande samtal uppstår en känsla av tillit och när detta sker vågar patienten och vårdaren kommunicera på ett öppet sätt där de båda är närvarande i situationen
