- The objectives of this study were to evaluate registered nurses' (RN) compliance with a local clinical central venous access device (CVAD) protocol after completing an educational program and to determine RNs' perception of the program. Seventy-five RNs working in hematology participated in the educational part of the program. Sixty-eight RNs were examined while changing CVAD dressings or placing a Huber needle into a port on actual patients. Sixty percent of the RNs passed the examination and reported that the program increased their knowledge. The results indicated that the educational program could be recommended for use when implementing a new clinical protocol.

- Background: High iron levels can increase the formation of noxious oxygen radicals, which are thought to contribute to cerebrovascular disease. The aim of this prospective study was to determine if iron status and HFE genotypes constitute risk factors for stroke. Methods: First-ever stroke cases (231 ischemic and 42 hemorrhagic) and matched double referents from the population-based Northern Sweden cohorts were studied in a nested case-referent setting. Results: For total iron binding capacity, an increased risk of ischemic stroke was seen in the highest quartile (OR 1.80; 95% CI 1.14-2.83; p for trend 0.012). The highest quartile of transferrin iron saturation showed a decreased risk of ischemic stroke in men (OR 0.44; 95% CI 0.22-0.87; p for trend 0.028), but not in women. There was an increased risk of hemorrhagic stroke in the second (OR 4.07; 95% CI 1.09-15.20) and third quartile (OR 4.22; 95% CI 1.08-16.42) of ferritin. Neither quartiles of plasma iron concentrations nor the HFE C282Y and H63D genotypes were associated with ischemic or hemorrhagic stroke. Conclusions: Iron stores were not positively related to increased risk of ischemic stroke. Furthermore, HFE genotypes did not influence the risk of ischemic or hemorrhagic stroke.

Journal article (peer-reviewed)abstract
- Background: Chronic infections and associated inflammatory markers are suggested risk factors for cardiovascular diseases (CVD) and stroke. The proinflammatory cytokine interleukin (IL)-1β is suggested to play a role in the regulation of local inflammatory responses in both CVD and periodontitis. The leukotoxin from the periodontal pathogen Actinobacillus actinomycetemcomitans has recently been shown to cause abundant secretion of IL-1β from macrophages. The aim of the present study was to compare the prevalence of systemic antibodies to A. actinomycetemcomitansleukotoxin in stroke cases (n = 273) and matched controls (n = 546) in an incident case-control study nested within the Northern Sweden MONICA and Västerbotten Intervention cohorts. Methods: Antibodies to A. actinomycetemcomitans leukotoxin were analyzed in a bioassay with HL-60 cells (leukocytes), purified A. actinomycetemcomitans leukotoxin, and plasma. Plasma samples which inhibited lactate dehydrogenase release from leukotoxin-lysed cells by ≥50% were classified as antibody positive. Results: Antibodies to A. actinomycetemcomitans leukotoxin were detected in 18.8% of the women and 15.2% of the men. Women with those antibodies had a significantly decreased risk for stroke (OR = 0.28, 95% CI: 0.13–0.59), but not men (OR = 0.88, 95% CI: 0.52–1.51). Conclusion: The immunoreactivity to A. actinomycetemcomitans leukotoxin correlates negatively with a future stroke in woman, but not in men. Further studies are needed to explain the underlying mechanisms, as well as the biological relevance of this finding.

Journal article (peer-reviewed)abstract
- AIMS: Our aim was to compare the long-term effects on rhythm and quality of life (QoL) after left atrial epicardial radiofrequency (RF) ablation vs. no ablation in patients undergoing cardiac surgery. METHODS AND RESULTS: Thirty-nine patients with ECG documented atrial fibrillation (AF) scheduled for coronary artery bypass grafting (CABG) with or without concomitant valve surgery were consecutively elected for epicardial RF ablation. Thirty-nine age- and gender-matched patients scheduled for CABG with or without concomitant valve surgery only and with documented AF served as controls. The follow-up after ablation was 32 +/- 11 months. The percentage of patients in sinus rhythm (SR) at long-term follow-up was 62 vs. 33% (P = 0.03) after ablation and no ablation, respectively. SR at 3 months was highly predictive of that at 32 months (sensitivity 95%, positive predictive value 86%). Long-term SR was associated with better QoL, fewer symptoms, higher ejection fraction, and smaller left and right atria than AF. CONCLUSION: SR at 3 months was highly predictive of long-term SR that was associated with clinical improvement when compared with patients still in AF. AF at 3 months did not preclude a later stabilization to SR.

Eating problems in patients with head and neck cancer treated with radiotherapy : Needs, problems and support during the trajectory of care
- 2006
-
Doctoral thesis (other academic/artistic)abstract
- Aim: The overall aim of this thesis was to acquire knowledge about daily life with focus on eating problems during the trajectory of care for patients with head and neck cancer treated with radiotherapy. Method: The data in study I were gained from medical and nursing records of 50 patients. Documented parameters of eating problems, their causes and consequences, and undertaken interventions were collected before treatment, during radiotherapy, and one, six, and twelve months after completion of treatment, using a study-specific audit instrument. Data were analysed with descriptive and inferential non-parametric statistics. In study II eight patients were interviewed during the radiotherapy treatment period with focus on experiences of eating problems. In study III nine patients were interviewed six to twelve weeks after treatment with the focus on experiences of daily life during the trajectory of care having eating problems. In study IV twelve patients were interviewed about their conceptions of the significance of a supportive nursing care clinic during the whole trajectory of care. Data were analysed with interpretative phenomenology (II, III) and phenomenography (IV). Findings: The four studies showed that being a patient in the trajectory of care often meant that life was disturbed and threatened. This was partly due to the eating problems and their consequences, which could occur during the whole trajectory of care (I, III, IV) but was experienced as most intense and severe during radiotherapy (II) and the nearest weeks after completion of radiotherapy (III, IV). The disturbances and threats experienced due to eating problems could affect the whole person as they were physical (I-IV), psychological, social and existential (II, III). The experiences of eating problems due to the tumour and its treatment and the experience of having cancer per se were strongly connected as one phenomenon, which disturbed and threatened the informants’ daily life. The other part that disturbed the patients’ life was the waiting in suspense. A long and trying waiting in uncertainty was experienced due to lack of knowledge and support, practical as well as emotional. This was most pronounced during pauses in radiotherapy (III) and after completion of the treatment when the lack of support from the health care was obvious (I, II, III). The patients were then most often left to their own devices. In order to endure, they needed both inner strength, described as own coping strategies, and strength from outside, described as support from family, friends and health care professionals (II, III). The nurse clinic was found to give a hand to hold during the whole trajectory of care (IV). It could meet these patients’ needs of knowledge, care and support, both concerning practical measures related to the eating problems and other side-effects of the treatment, and concerning their emotional needs. In addition the nurse clinic could support the relatives in their worries and anxiety (IV). Conclusion: This thesis showed the necessity of continuous assessment, treatment and evaluation of patients’ problems, and the patients’ needs of information and support throughout the trajectory of care.

Journal article (peer-reviewed)abstract
- Since 1986, 68% of the Listeria monocytogenes isolates from human cases of invasive listeriosis in Sweden are available for retrospective studies. The aim of the present study was to characterize 601 human invasive isolates of L. monocytogenes in Sweden from 1986 to 2007 by using serotyping and pulsed-field gel electrophoresis. Since 1996, serovar 4b was permanently reduced to the second or third most common serovar in human cases in Sweden. During the latter period, 2000-2007, only 13% belonged to serovar 4b and 71% to 1/2a. The dendrogram, based on pulsovars, reveals two clusters with different serovars. Cluster 1 exhibits serovars 4b and 1/2b, whereas cluster 2 consists of serovar 1/2a. Serovar 1/2a seems to be more heterogeneous than serovar 4b.
