  • Evaluation of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) in persons with heart disease : A pilot study
  • 2010
  • Ingår i: European Journal of Cardiovascular Nursing. - 1474-5151. ; 9:3, s. 168-174
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: As part of preparation for a Swedish multicentre study, exploring sexual and married life in patients with myocardial infarction and their partners, a Swedish validated instrument was required.Aims: The aim of this pilot study was to evaluate the validity and reliability of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) among persons with a heart disease.Methods: A convenience sample of 79 persons (47 men and 32 women) living with a heart disease was recruited from the members of the National Association of Heart and Lung Patients. They completed a Swedish version of the WSFQ on two occasions.Results: Two separate factor analyses each revealed a two-factor structure on both occasions: “Sexual appetite” and “Sexual expectations” with gender-neutral questions and “Sexual sensitiveness” and “Sexual ability” with gender-specific questions. Cronbach's alpha coefficients ranged from 0.48 to 0.86 and test–retest values for all but one question exceeded 0.70.Conclusions: The Swedish version of the WSFQ showed good validity and stability and acceptable internal homogeneity. Extended evaluations of the questionnaire are recommended.

  • Validity and reliability of a Swedish version of the Relationship Assessment Scale (RAS) : a pilot study
  • 2010
  • Ingår i: Canadian journal of cardiovascular nursing. - Ottawa : Canadian Council of Cardiovascular Nurses. - 0843-6096. ; 20:1, s. 16-21
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: There is a need for a short and easily administered scale, in the Swedish language, for assessing partner relationships in the health care of persons with cardiac disease. PURPOSE: To establish the reliability and validity of the Swedish version of the Relationship Assessment Scale (RAS). DESIGN: The present pilot study has a methodological design. FINDINGS: Content validity has been tested for relevance, clarity and readability. The scale was tested for construct validity with explorative factor analysis. The reliability was tested by internal consistency and test-retest analysis. The result showed a two-factor solution, which does not correspond to the original proposed one-factor solution. The factor analyses revealed two quite distinct factors of RAS, labelled "Relationship built on expectations and satisfaction of needs" and "Relationship built on love and devotion". CONCLUSIONS: The scale has satisfactory psychometric properties in terms of content validity, construct validity, homogeneity and stability in a population of persons with cardiac disease. Wider evaluations of the RAS for other populations and settings are recommended.

  • Sexual knowledge in patients with a myocardial infarction and their partners
  • 2014
  • Ingår i: Journal of Cardiovascular Nursing. - 0889-4655. ; 29:4, s. 332-339
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Sexual health and sexual activity are important elements of an individual's well-being. For couples, this topic is often affected after a myocardial infarction (MI). It has become increasingly clear that, after an MI, patients are insufficiently educated on how to resume normal sexual activity. However, sufficient data on the general knowledge that patients and partners have about sexual activity and MI are lacking.OBJECTIVE: The aims of this study were to explore and compare patients' and partners' sexual knowledge 1 month after a first MI and 1 year after the event and to compare whether the individual knowledge had changed over time. A second aim was to investigate whether patients and their partners report receiving information about sexual health and sexual activity from healthcare professionals during the first year after the event and how this information was perceived.SUBJECTS AND METHODS: This descriptive, comparative survey study enrolled participants from 13 Swedish hospitals in 2007-2009. A total of 115 patients with a first MI and their partners answered the Sex After MI Knowledge Test questionnaire 1 month after the MI and 1 year after the event. Correct responses generated a maximum score of 75.RESULTS: Only 41% of patients and 31% of partners stated that they had received information on sex and relationships at the 1 year follow-up. The patients scored 51 ± 10 on the Sex After MI Knowledge Test at inclusion into the study, compared with the 52 ± 10 score for the partners. At the 1-year follow-up, the patients' knowledge had significantly increased to a score of 55 ± 7, but the partners' knowledge did not significantly change (53 ± 10).CONCLUSIONS: First MI patients and their partners reported receiving limited information about sexual issues during the cardiac rehabilitation and had limited knowledge about sexual health and sexual activity.

  • The female partners' experiences of intimate relationship after a first myocardial infarction
  • 2011
  • Ingår i: Journal of Clinical Nursing. - 0962-1067. ; 20:11/12, s. 1677-1684
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim. This study aimed to explore and describe women’s experience of intimate relationships in connection to and after their partner’s first myocardial infarction (MI).Background. Support from partners is important for recovery, but little is known about partners’ experience of intimate relationships after MI.Design. The study used an explorative, qualitative design.Methods. The first author interviewed 20 women having a partner who had suffered a first MI during the preceding year. Qualitative content analysis was used to analyse the data.Findings. Three themes emerged: ‘limited life space’, ‘sense of life lost’ and ‘another dimension of life’. The women described how their self-assumed responsibility led to a more stifling and limited life. Their sense of life lost was described in terms of deficits and feeling the loss. The women also described experiencing another dimension of life characterised by three subthemes: ‘uncertainty of life’, ‘certain of relationship’ and ‘share life more’.Conclusions. The partners’ MI had an impact on the interviewees’ intimate relationships; they suffered a major loss and missed their ‘former’ partner, both emotionally and sexually. They struggled with the new asymmetry in their intimate relationship and felt compelled to adapt to their partners’ lack of sexual desire or function. Also, their partner controlled them, which lead towards a stifling, more limited life space.Relevance to clinical practice. Caregivers in hospital and primary care settings could apply the findings in their efforts to help couples recover or maintain intimate relationships following MI.

  • The male partners' experiences of the intimate relationships after a first myocardial infarction
  • 2011
  • Ingår i: European Journal of Cardiovascular Nursing. - 1873-1953. ; 10:2, s. 108-114
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Stress in the intimate relationship is found to worsen the prognosis in women suffering from myocardial infarction (MI). Little is known about how male spouses experience the intimate relationship.Aim: This study aimed to explore and describe the experience of men's intimate relationships in connection to and after their female partner's first MI.Methods: An explorative and qualitative design was used. Interviews were conducted with 16 men having a partner who the year before had suffered a first MI. The data were analysed with qualitative content analysis. Results: Three themes emerged: masculine image challenged; life takes another direction; and life remains unchanged. The men were forced to deal with an altered image of themselves as men, and as sexual beings. They were hesitant to approach their spouse in the same way as before the MI because they viewed her to be more fragile. The event also caused them to consider their own lifestyle, changing towards healthier dietary and exercise habits.Conclusions: After their spouse's MI, men experienced a challenge to their masculine image. They viewed their spouse as being more fragile, which led the men to be gentler in sexual intimacy and more hesitant to invite sexual activity. This knowledge about how male spouses experience the intimate relationship could be helpful for health personnel in hospitals and primary care when they interact with couples where the woman suffers from cardiac disease or other chronic disorders.

  • Weight increase in patients with dementia, and alteration in meal routines and meal environment after integrity promoting care
  • 2007
  • Ingår i: JOURNAL OF CLINICAL NURSING. - 0962-1067. ; 16:5, s. 987-996
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: To follow weight changes in patients with moderate and severe dementia and analyse how these changes related to biological and psychological parameters after staff education and support in integrity promoting care. A further aim was to describe meal environment and routines relative to the intervention. BACKGROUND: Weight loss in patients with dementia and in particular Alzheimer's disease is common. The aetiology appears multifactorial with the meal environment and a decreased independence while eating among the factors. METHOD: Over a three-month intervention period, an integrity-promoting care training programme was conducted with the staff of a long-term ward. Alzheimer's disease patients, 18 from an intervention ward and 15 from a control ward were included and possible effects were evaluated. Weighing was conducted at the start and after completion of the intervention. Weight changes were analysed in relation to psychological and biochemical parameters. In addition, the staff wrote diaries about, for example changes made in the environment and in their work. RESULTS: The most prominent difference observed was weight increases in 13 of 18 patients compared with two of 15 patients in the control ward. No weight changes were related to the type of dementia. The individual weight changes correlated significantly to changes in the intellectual functions. Relationships between weight change, increased motor function and increased appetite were non-significant. There was no significant relationship between weight changes and changes in biochemical parameters. According to the staff, increased contact with the patients and a more pleasant atmosphere resulted when the meal environment and routines were changed. RELEVANCE TO CLINICAL PRACTICE: Weight gain in patients with moderate and severe dementia was achieved by adjusting the meal environment to the individual's needs. Staff education was profitable, as increased competence seemed to promote individually adapted feeding situations. Ensuring good meal situations need to be given high priority.

  • Skeletal muscle morphology in power-lifters with and without anabolic steroids
  • 2005
  • Ingår i: Histochemistry and Cell Biology. - 0948-6143. ; 124:2, s. 167-175
  • Tidskriftsartikel (refereegranskat)abstract
    • The morphological appearance of the vastus lateralis (VL) muscle from high-level power-lifters on long-term anabolic steroid supplementation (PAS) and power-lifters never taking anabolic steroids (P) was compared. The effects of long- and short-term supplementation were compared. Enzyme-immunohistochemical investigations were performed to assess muscle fiber type composition, fiber area, number of myonuclei per fiber, internal myonuclei, myonuclear domains and proportion of satellite cells. The PAS group had larger type I, IIA, IIAB and IIC fiber areas (p<0.05). The number of myonuclei/fiber and the proportion of central nuclei were significantly higher in the PAS group (p<0.05). Similar results were seen in the trapezius muscle (T) but additionally, in T the proportion of fibers expressing developmental myosin isoforms was higher in the PAS group compared to the P group. Further, in VL, the PAS group had significantly larger nuclear domains in fibers containing > or = 5 myonuclei. The results of AS on VL morphology in this study were similar to previously reported short-term effects of AS on VL. The initial effects from AS appear to be maintained for several years.

  • Short-term effects of repetitive arm work and dynamic exercise on glucose metabolism and insulin sensitivity.
  • 2005
  • Ingår i: Acta Physiologica Scandinavica. - 0001-6772. ; 183:4, s. 345-356
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: To determine whether repetitive arm work, with a large component of static muscle contraction alters glucose metabolism and insulin sensitivity.METHOD: Euglycemic clamps (2 h) were started in ten healthy individuals 15 min after 37 min periods of: (1) repetitive arm work in a simulated occupational setting; (2) dynamic concentric exercise on a cycle ergometer at 60% of VO(2max) and (3) a resting regime as a control. During the experimental periods, blood samples were collected, blood pressure was measured repeatedly and electrocardiogram (ECG) was recorded continuously. During the clamps, euglycemia was maintained at 5 mmol l(-1) and insulin was infused at 56 mU m(-2) min(-1) for 120 min.RESULTS: The insulin-mediated glucose disposal rate (M-value) for the steady-state period (60-120 min) of the clamp, tended to be lower following arm work than for both cycling and resting regimes. When dividing the steady-state period into 20-min intervals, the insulin sensitivity index (ISI) was significantly lower for arm work compared with the resting control situation between 60-80 min (P = 0.04) and 80-100 min (P = 0.01), respectively. Catecholamines increased significantly for arm work and cycling compared with resting regime. Data from heart rate variability (HRV) measurements indicated significant sympathetic activation during repetitive arm work.CONCLUSION: The results indicate that repetitive arm work might acutely promote insulin resistance, whereas no such effect on insulin resistance was produced by dynamic concentric exercise.

  • Acute effects of vibration on thermal perception thresholds
  • 2008
  • Ingår i: International Archives of Occupational and Environmental Health. - Springer. - 0340-0131. ; 81:5, s. 603-611
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: This study focuses on the acute effects of vibration and how vibrations influence the measures of the thermal perception thresholds during different vibration magnitudes, frequencies, and durations. METHODS: The fingers of ten healthy subjects, five males and five females, were exposed to vibration under 16 conditions with a combination of different frequency, intensity and exposure time. The vibration frequency was 31.5 and 125 Hz and exposure lasted between 2 and 16 min. The energy-equivalent frequency weighted acceleration, according to ISO 5349-1, for the experimental time of 16 min was 2.5 or 5.0 m/s(2) (r.m.s.), corresponding to a 8-h equivalent acceleration, A(8) of 0.46 and 0.92 m/s(2), respectively. A measure of the thermal perception of cold and warmth was conducted before the different exposures to vibration. Immediately after the vibration exposure the acute effect was measured continuously on the exposed index finger for the first 75 s, followed by 30 s of measures at every minute for a maximum of 10 min. If the subject's thermal thresholds had not recovered, the measures continued for a maximum of 30 min with measurements taken every 5 min. RESULTS: For all experimental conditions and 30 s after exposure, the mean changes of the thresholds compared with the pre-test were found to be 0.05 and -0.67 degrees C for the warmth and cold thresholds, respectively. The effect of the vibration exposure was only significant on the cold threshold and only for the first minute after exposure when the threshold was decreased. The warmth threshold was not significantly affected at all. The frequency and the exposure time of the vibration stimuli had no significant influence on the perception thresholds for the sensation of cold or warmth. Increased equivalent frequency weighted acceleration resulted in a significant decrease of the subjects' cold threshold, not the warmth. The thresholds were unaffected when changes in the vibration magnitude were expressed as the frequency weighted acceleration or the unweighted acceleration. CONCLUSION: When testing for the thermotactile thresholds, exposure to vibration on the day of a test might influence the results. Until further knowledge is obtained the previous praxis of 2 h avoidance of vibration exposure before assessment is recommended.

  • Effects of 30 versus 60 minutes of low-load work on intramuscular lactate, pyruvate, glutamate, prostaglandin E2 and oxygenation in the trapezius muscle of healthy females
  • 2006
  • Ingår i: European Journal of Applied Physiology. - 1439-6319. ; 97:5, s. 557-565
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to investigate the effects of duration of low-load repetitive work on intramuscular lactate, pyruvate, glutamate and prostaglandin E2 (PGE2), and oxygen saturation in the trapezius muscle. Twenty healthy females were studied during baseline rest, during low-load repetitive work for either 30 (REP 30) or 60 (REP 60) minutes, and 60 minutes recovery. Intramuscular microdialysate (IMMD) samples were obtained, and local muscle tissue oxygenation (StO2 %) assessed with near infrared spectroscopy (NIRS). Subjects rated their perceived exertion (Borg CR-10 scale) and capillary blood was sampled for lactate analysis. The results showed a significant increase in IMMD lactate in response to both REP 30 and REP 60 (P<0.05 and P<0.01 respectively) and glutamate (P<0.0001), but no progressive increase with increasing work duration. Both IMMD pyruvate and lactate tended to be significantly increased during the recovery period. No corresponding increase in blood-lactate was found. Local muscle StO2 % did not change significantly in response to work and was not correlated to the IMMD lactate concentration. The ratings of perceived exertion increased in response to work, and remained increased after recovery for REP 60.In conclusion, the results of this study show significantly increased IMMD lactate and, glutamate concentrations in the trapezius muscle of healthy females in response to low-load work, but no progressive increase with increased work duration. Further, they do not indicate that the increased IMMD lactate concentration was caused by a locally decreased or insufficient muscle tissue oxygenation.
