- The aim of this study was to examine the effect of high intensity physical group training in water and on land for patients with COPD with regard to physical capacity and health related quality of life (HRQoL). A controlled, semi-randomised study was conducted where 30 patients were randomised to training either in water or on land. Thirteen patients constituted a control group. Forty-three outpatients, with moderate to severe COPD (27w/16m), from two local hospitals in northern Sweden, were included in the study. High intensity physical group training in water (water group) or on land (land group) was performed for 12weeks, three times per week, 45min per session. The control group received no intervention. Pre- and post-intervention, all patients performed incremental and endurance shuttle walking tests (ISWT and ESWT), cycle ergometer tests and responded questionnaires about HRQoL (St. Georges Respiratory Questionnaire--SGRQ and SF-36). The patients trained with a mean heart rate of 80-90% of peak heart rate. Both training groups increased the distance walked, i.e. land group in ISWT (25m) and water group in ESWT (179m). The water group increased the distance in ESWT significantly more that both the land and the control groups. Both training groups increased the time cycled (40-85s) and work load (10-20W) in the cycle ergometer test. The control group deteriorated in HRQoL according to total score in SGRQ while the training groups remained constant. The water group improved their activity score in SGRQ and their physical health score in SF-36 and those improvements were significant as compared to the land and the control groups. In conclusion, high intensity physical group training in water is of benefit for patients with COPD. It was in some areas found to be even more effective regarding improvements in physical capacity and experienced physical health compared to the same kind of training on land.

- A randomized, controlled, single-blind study was performed on 20 patients with chronic obstructive pulmonary disease and exercise-induced hypoxaemia. Ten patients each were randomly assigned to one of two groups, one training with air and the other training with oxygen. There were no significant differences between the groups regarding values measured prior to the study. The patients trained 3 times per week for 30 minutes each time for a duration of 8 weeks. The training consisted of interval walking on a treadmill (intensity set according to Borg ratings) with either air or oxygen administered through a nasal cannula at a rate of 5 l/min. Training significantly improved the 6-minute walking distance by 20% and 14% in the air and oxygen group, respectively, when the patients were tested on air. In the same test the air group significantly decreased Borg ratings for perceived exertion. Borg ratings for dyspnoea and perceived exertion significantly decreased in the oxygen group when they were tested on oxygen. It was concluded that oxygen supplementation did not further improve the training effect, compared with training with air, in patients with chronic obstructive pulmonary disease and exercise-induced hypoxaemia.

- Objectives: To compare detection and pain thresholds in the skin of female fibromyalgia patients who were either ketamine responders or ketamine nonresponders.Methods: Detection thresholds to innocuous warmth, of cold, heat or cold pain, and touch and dynamic touch sensation were determined in the skin. Pressure pain thresholds, local and widespread pain intensity, and pain duration were also registered.Results: Ketamine nonresponse was associated with more pronounced hypersensitivity for thermal pain [especially cold pain] than ketamine response.Conclusions: Blockade of N-metyl-D-aspartic acid receptors by ketamine and the recording of pain thresholds in the skin, especially for cold pain, might reveal different mechanisms of allodynia.

101 Women's patterns of daily occupations : Characteristics and realtionships to health and well-being
- 2003

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis investigated the concept of balance in daily occupations. The overarching aim was to explore women’s patterns of everyday occupations and to investigate relationships between different aspects of patterns of daily occupations and health and well-being. The participants were working, cohabitant women with pre-school children. The methods used focused on exploring patterns of daily occupations and assessing sociodemographic aspects, self-rated health, and well-being. The results imply methodological development for documenting patterns of daily occupations, measuring occupation-related experiences associated with daily occupations, and categorising patterns of daily occupations according to complexity. This thesis identified the building blocks of patterns of daily occupations as main, hidden and unexpected occupations. Women’s hassling experiences associated with daily occupations were generated mainly by the social environment and their uplifting experiences resulted primarily from performing occupations. Moreover, typical patterns of daily occupations with respect to complexity were identified, and relationships of complexity in patterns of daily occupations to health and well-being were investigated. The result indicated that more hassles in combination with low control and high complexity in pattern of daily occupations mean an increased risk of experiencing low health and well-being. The findings contribute to the knowledge base of occupational science by further illuminating the concept of pattern of daily occupations: its constituents and its complexity. The results contribute to research on women’s total workload in relation to a sense of well-being and give implications for occupational therapy intervention for people who have taken ill due to imbalance in their pattern of daily occupations.

- PURPOSE: To investigate relationships between heart rate variability (HRV) and peripheral and central performance measures, 17 cross-country (X-C) skiers and seven canoeists were studied before and after a training period of 7 months. METHODS: For the skiers and canoeists respectively, leg and arm peak torque (Tq), time to peak torque (TiTq), and total work (Wrk) were measured in an isokinetic dynamometer. Maximal oxygen uptakes (VO(2max)) were obtained from treadmill tests. Power spectral analysis of HRV was performed on electrocardiographic recordings in the resting supine position and after a tilt to yield power in the low-frequency (0.04--0.15 Hz) and high-frequency (0.15--0.45 Hz) components of HRV. RESULTS: The change in normalized LF-variability in standing (Delta LFnT) correlated (P < 0.01) with the changes in TiTq (r = 0.63), max lactate (r = -0.63), and VO(2max) (r = -0.53). The change in absolute LFT was inversely correlated with the change in Tq. Subjects who improved VO(2max) were characterized by consistently higher high-frequency and total HRV than subjects with deteriorated aerobic capacity (P < 0.05). CONCLUSION: The results suggest that improved measures of both peripheral and central (aerobic) work capacities were associated with a reduction of low-frequency HRV in the tilted position. High-frequency and total HRV did not change in proportion with changes in muscle performance or aerobic capacity, but the ability to further improve VO(2max) with training in these already fit subjects seemed to depend on their average levels of these HRV measures, interpreted to reflect parasympathetic activity.

- PURPOSE AND METHODS: Nine elite canoeists were investigated concerning changes in performance, heart rate variability (HRV), and blood-chemical parameters over a 6-d training camp. The training regimen consisted of cross-country skiing and strength training, in total 13.0+/-1.6 h, corresponding to a 50% increase in training load. RESULTS: Time to exhaustion (RunT) decreased from 19.1+/-1.0 to 18.0+/-1.2 min (P < 0.05). VO2max and max lactate (La(max)) both decreased significantly (P < 0.05) over the training period (4.99+/-0.97 to 4.74+/-0.98 L x min(-1) and from 10.08+/-1.25 to 8.98+/-1.03 mmol x L(-1) respectively). Heart rates (HR) decreased significantly at all workloads. Plasma volume increased by 7+/-7% (P < 0.05). Resting cortisol, decreased from 677+/-244 to 492+/-222 nmol x L(-1) (P < 0.05), whereas resting levels of adrenaline and noradrenaline remained unchanged. The change between tests in RunT correlated significantly with the change in HRmax (r = 0.79; P = 0.01). There were no group changes in high or low frequency HRV, neither at rest nor following a tilt. CONCLUSIONS: The reduced maximal performance indicates a state of fatigue/overreaching and peripheral factors are suggested to limit performance even though HRmax and La(max) both were reduced. The reduced submaximal heart rates are probably a result of increased plasma volume. HRV in this group didn't seem to be affected by short-term overtraining.

- BACKGROUND: Short body height is associated with increased risk for coronary heart disease; however, mechanisms are not fully explained. In this study, associations between body height and serum cholesterol, non-high-density lipoprotein (non-HDL cholesterol) and high-density lipoprotein (HDL cholesterol) were investigated. METHODS: Prospective cohort study of middle-aged men from Helsingborg, Sweden starting 1990. Two birth-year cohorts were invited at 37, 40 and 43 years of age; participation at baseline was 991 (68%). Serum and HDL cholesterol, systolic and diastolic blood pressure, weight, height, waist and hip circumferences were measured. Non-HDL cholesterol, body mass index (BMI) and waist/ hip ratio (WHR) were calculated. The participants completed a questionnaire covering lifestyle variables. RESULTS: There were statistically significant inverse correlations between body height and serum cholesterol (-0.11) and non-HDL cholesterol (-0.12). One standard deviation, 6.7 cm, taller body height was associated with a lower serum cholesterol (-0.12 mmol/l) and a lower non-HDL cholesterol (-0.13 m mol/l; p < 0.001). These associations remained when adjusted for BMI and WHR. Men with serum cholesterol equal to or above 6.5 mmol/l were significantly shorter (mean 178.71 cm) than men with serum cholesterol below 6.5 mmol/l (mean 179.71 cm). In addition, BMI and WHR were positively associated with serum and non-HDL cholesterol and inversely associated with HDL cholesterol. The change in cholesterol levels over the six-year follow-up was significantly associated to the change in BMI and WHR. CONCLUSIONS: Body height had an independent and inverse relation to serum cholesterol and non-HDL cholesterol in middle-aged men, and the lipid pattern suggests that the underlying mechanism might be different from the traditional association between lipids and the metabolic syndrome. Although the direct clinical implication is limited, our results may help to explain the association between short height and risk of myocardial infarction.

- Aims: To investigate associations between CVD risk factors and socio-economic status (SES) in middle-age men during a period of economic changes. Methods: Crossectional surveys at age 37, 40 and 43 in a birth cohort of men in Helsingborg, Sweden. All male residents born 1953 - 4 (n=1460) were invited; participation rates were 68% (n=991) at baseline. Of these enrolled, 78% (n=770) were re-examined after three years and 71% (n=702) again after six years follow-up. Main outcome measures were body mass index (BMI), S-cholesterol, HDL-cholesterol, systolic and diastolic blood pressure (SBP, DBP), smoking and leisure time physical activity (LTPA), education, employment, ethnicity. Results: Baseline unemployment rate was low, n=23 (2.4%), but three and six years later it had increased to 61 (8.2%) and 51 (7.5%) respectively. At baseline, BMI and S-cholesterol were significantly higher in unemployed than in employed men (ΔBMI 1.6 kg/m2, CI: 0.2; 2.9, Δ S-cholesterol 0.6 mmol/L, CI: 0.1; 1.0), and in men with short versus long education (Δ BMI 0.9 kg/m2, CI: 0.4; 1.4, Δ S-cholesterol 0.2 mmol/L, CI: 0.03: 0.4), independent of other SES factors. Over the study period crossectional associations with employment status disappeared for BMI, but remained between short education and BMI. Short education was also associated with a significant increase in BMI (Δ=0.4 kg/m2, CI: 0.1; 0.7) during 6-year follow-up. Conclusions: This study shows that associations between unemployment and CVD risk factors were lost when unemployment rates increased. When the attributable risk of unemployment associated with CVD risk factors is estimated, it is vital to consider the general unemployment rates in society.

Development of cardiovascular disease risk in middle-aged men. The Cardiovascular Risk Factor Study in Southern Sweden, CRISS.
- 2002

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Cardiovascular Risk Factor Study in Southern Sweden, CRISS, was initiated to explore if men at increased risk at developing CVD risk factors can be identified already before age 40. Starting in 1990 two birth cohorts of men residing in Helsingborg, Sweden, were surveyed at age 37 (n=991, participation rate 68%), at age 40 (n=770) and age 43 (n=702), respectively. A study questionnaire, a physical examination, and blood samples were required for participation. · An annual increase by 0.04 mmol/L in S-Cholesterol was accounted for by a rise in Non-HDL-Cholesterol. · Body height was independently and inversely associated with high (baseline) and increasing S-Cholesterol and Non-HDL-Cholesterol. · Associations between unemployment and CVD risk factors were lost when general unemployment rates increased, whereas associations with length of education remained consistent over the study period. · Overweight, high alcohol consumption and being born abroad, were strong determinants for increasing blood pressure. · At baseline 35% of the men were hypertensive (³140/90 mm Hg), a proportion that increased to 49% over six years. Men with high normal blood pressure (130-139/85-89 mm Hg) at baseline had a higher risk to develop hypertension (OR 2.4, CI: 1.59; 3.80) than men with normal blood pressure (<130/85 mm Hg). This study shows that men at increased risk of developing important CVD risk factors accessible to life style modifications can be identified already before 40 years of age. This has important implications both for clinical practise, and from a public health perspective. The main conclusion of CRISS is to change the aims of primary prevention from the prevention of CVD to of increased CVD risk
