- The maintenance of good oral health is essential for nutrition, recovery and well-being. This requires the involvement of the nursing staff, especially in cases where oral care and any necessary dental treatment are vital to ensure medical treatment. The aim of this study was to evaluate the validity of oral assessments performed by nursing staff using the revised oral assessment guide (ROAG), using comparisons with patients' self-assessment of oral problems. When a comparison was made of how the staff and patients assessed their oral status, a high level of agreement was found. In these assessments, with the exception of oral mucosa and teeth, the percentage agreement was >80. The kappa coefficient revealed slight to moderate agreement. When there was a disagreement, the staff assessed the oral health as being significantly poorer than the patients did. In the present study, it was shown that few oral assessments performed by the nursing staff and patient disagreed. The ROAG may therefore be useful for the nursing staff to make the patients' oral health problems visible. © 2007 The Authors; Journal compilation © 2007 Blackwell Publishing Ltd.

- The natural reservoir of influenza A virus is waterfowl, particularly dabbling ducks (genus Anas). Although it has long been assumed that waterfowl are asymptomatic carriers of the virus, a recent study found that low-pathogenic avian influenza (LPAI) infection in Bewick's swans (Cygnus columbianus bewickii) negatively affected stopover time, body mass and feeding behaviour. In the present study, we investigated whether LPAI infection incurred ecological or physiological costs to migratory mallards (Anas platyrhynchos) in terms of body mass loss and staging time, and whether such costs could influence the likelihood for long-distance dispersal of the avian influenza virus by individual ducks. During the autumn migrations of 2002-2007, we collected faecal samples (n = 10 918) and biometric data from mallards captured and banded at Ottenby, a major staging site in a flyway connecting breeding and wintering areas of European waterfowl. Body mass was significantly lower in infected ducks than in uninfected ducks (mean difference almost 20 g over all groups), and the amount of virus shed by infected juveniles was negatively correlated with body mass. There was no general effect of infection on staging time, except for juveniles in September, in which birds that shed fewer viruses stayed shorter than birds that shed more viruses. LPAI infection did not affect speed or distance of subsequent migration. The data from recaptured individuals showed that the maximum duration of infection was on average 8.3 days (s.e. 0.5), with a mean minimum duration of virus shedding of only 3.1 days (s.e. 0.1). Shedding time decreased during the season, suggesting that mallards acquire transient immunity for LPAI infection. In conclusion, deteriorated body mass following infection was detected, but it remains to be seen whether this has more long-term fitness effects. The short virus shedding time suggests that individual mallards are less likely to spread the virus at continental or intercontinental scales.

- Pressure ulcers (PU) in patients with hip fracture remain a problem. Incidence of between 8.8% and 55% have been reported. There are few studies focusing on the specific patient-, surgery- and care-related risk indicators in this group. The aims of the study were: - to investigate prevalence and incidence of PU upon arrival and at discharge from hospital and to identify potential intrinsic and extrinsic risk factors for development of PU in patients admitted for hip fracture surgery, - to illuminate potential differences in patient logistics, surgery, PU prevalence and incidence and care between Northern and Southern Europe. Consecutive patients with hip fracture in six countries, Sweden, Finland, UK (North) and Spain, Italy and Portugal (South), were included. The patients were followed from Accident and Emergency Department and until discharge or 7 days. Prevalence, PU at discharge and incidence were investigated, and intrinsic and extrinsic risk indicators, including waiting time for surgery and duration of surgery were recorded. Of the 635 patients, 10% had PU upon arrival and 22% at discharge (26% North and 16% South). The majority of ulcers were grade 1 and none was grade 4. Cervical fractures were more common in the North and trochanteric in the South. Waiting time for surgery and duration of surgery were significantly longer in the South. Traction was more common in the South and perioperative warming in the North. Risk factors of statistical significance correlated to PU at discharge were age >or=71 (P = 0.020), dehydration (P = 0.005), moist skin (P = 0.004) and total Braden score (P = 0.050) as well as subscores for friction (P = 0.020), nutrition (P = 0.020) and sensory perception (P = 0.040). Comorbid conditions of statistical significance for development of PU were diabetes (P = 0.005) and pulmonary disease (P = 0.006). Waiting time for surgery, duration of surgery, warming or non warming perioperatively, type of anaesthesia, traction and type of fracture were not significantly correlated with development of PU.

- Few studies have focussed on patients' experiences of and suffering due to mediastinitis following Coronary Artery by-pass Graft (CABG). Mediastinitis creates a complex and invasive experience for the patient with prolonged hospitalisation, and would be expected to be a significant stressor. The aim of the present study was to capture patients' experiences of the medical and nursing care they received for mediastinitis following CABG. Content analysis revealed three themes with regard to how the patients coped with the stress and threats of mediastinitis and its treatment and how they thought it would influence their future life. A first theme centred on physical and psychological discomfort and impact on autonomy. The staff's medical knowledge and the quality of nursing care as well as the patients' understanding of the situation influenced their experience. A second theme was how patients dealt with perceived danger and stress. Coping strategies such as problem solving, information seeking, dissociation, distraction, minimisation and expression of emotion were used to handle the situations. The third theme comprised the patients' belief that the mediastinitis would not affect the outcome of the CABG procedure, even though their confidence in this was influenced by uncertainty about the rehabilitation process.

Radiographers' areas of professional competence related to good nursing care
- 2008
-
Ingår i: Scandinavian Journal of Caring Sciences. - : Wiley. - 0283-9318 .- 1471-6712. ; 22:3, s. 401-409

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Radiographers' ability and competence is a matter of vital importance for patients. Nursing care is an integral part of the radiographer's work. The demand for high competence in clinical activities has increased in diagnostic radiology and has had an impact on the development of the profession.AIM: The aim was to describe the radiographer's areas of professional competence in relation to good nursing care based on critical incidents that occur in the course of radiological examinations and interventions.METHOD: A descriptive design with a qualitative approach, using the Critical Incident Technique was employed. Interviews were conducted with a strategic sample of registered radiographers (n = 14), based at different hospitals in Sweden.ETHICAL ISSUES: The appropriate ethical principles were followed. All the participants provided informed consent, and formal approval for conducting the research was obtained according to national and local directives.RESULTS: The data analysis resulted in two main areas; direct and indirect patient-related areas of competence, which describe the radiographers' skills that either facilitate or hinder good nursing care. In the direct patient-related area of competence, four categories emerged, which illustrate good nursing care in the patient's immediate surroundings. In the indirect patient-related area of competence, four categories illuminated good nursing care that is provided without direct contact with the patient.CONCLUSIONS: The study highlights the different areas of the radiographer's unique professional competence. The findings provide insight into the radiographer's profession, on one hand as a carer and on the other as a medical technologist as well as highlighting the importance of each role. The radiographer's work encompasses a variety of components--from caring for the patient to handling and checking the technical equipment.

Strong antibacterial effect of miswak against oral microorganisms associated with periodontitis and caries.
- 2008

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The chewing stick (miswak) is used for oral hygiene in many parts of the world. In addition to the mechanical removal of plaque, an antibacterial effect has been postulated; however, tests of miswak extract from Salvadora persica (Arak) disclosed only low to moderate antibacterial effects. This may be attributable to the extraction process. Our aim was to test in vitro the antibacterial effect of miswak pieces, without extraction, on bacteria implicated in the etiology of periodontitis and caries. METHODS: Miswak pieces were standardized by size and weight (0.07 and 0.14 g) and tested against Streptococcus mutans, Lactobacillus acidophilus, Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans), Porphyromonas gingivalis, and, as a reference, Haemophilus influenzae. The miswak pieces were tested in two ways: embedded in the agar plate or suspended above the agar plate. RESULTS: The inhibitory effect was most pronounced on P. gingivalis, A. actinomycetemcomitans, and H. influenzae, less on S. mutans, and least on L. acidophilus. Suspended miswak had comparable or stronger effects than miswak embedded in agar. The 0.14-g suspended miswak exhibited significantly greater inhibition on A. actinomycetemcomitans and H. influenzae than the 0.14-g miswak embedded in agar (P<0.01 and P<0.001, respectively). CONCLUSIONS: Miswak embedded in agar or suspended above the agar plate had strong antibacterial effects against all bacteria tested. The antibacterial effect of suspended miswak pieces suggests the presence of volatile active antibacterial compounds.

Tidskriftsartikel (refereegranskat)abstract
- The understanding of the board of a corporation and its behavior is limited, despite the board’s societalimportance. We present a contingency approach to the board’s functional emphasis, considering afourth function in addition to monitoring, decision making, and service or resource provision. Theadditional function is conflict resolution (or principal identification). The approach contrasts withmainstream research by assuming that the firm is a nexus of investments, avoiding the empiricalassumption that the shareholder is the sole principal. We derive propositions that are not restricted toany empirical category of a corporation, and address praxis implications for managing functionaldisharmony.

Turnover and heterogeneity in top management networks : a demographic analysis of two Swedish business groups
- 2008
-
Ingår i: International Journal of Business Science and Applied Management. - Newcastle upon Tyne, UK : Brunel University. - 1753-0296. ; 3:3, s. 31-55

Tidskriftsartikel (refereegranskat)abstract
- A theory based on the demography of top management teams is used to explain membership turnover in two Swedish business groups, network analysis being used to define group membership. The results suggest these business groups possess a combination of financial and industrial experience as a group resource and the socialising strategy of control as a force counteracting the conflict-producing force of heterogeneity. An organisational demographic perspective focusing on opposing forces of heterogeneity and homogeneity is developed. It is shown that the perspective can be applied both to formal organisations and to informal ones such as networks.

“Let’s Keep it Informal, Guys” : a Study of the Effects of Teacher Communicative Strategies on Student Activity and Collaborative Learning in Internet-based English Courses
- 2008
-
Ingår i: Tidskrift för lärarutbildning och forskning. - Umeå : The faculty board for teacher education. - 1404-7659. ; 15:2, s. 36-58

Tidskriftsartikel (refereegranskat)abstract
- The paper explores the quantity and quality of communication produced by teachers in Internet courses of academic English, particularly during the initial stages of course activity. The courses are entirely conducted in virtual learning environments without physical meetings, and are part of the Bachelor programme (A–C level) of English at Mid Sweden University. The pedagogic design of the courses is based on collaborative learning, which presupposes a communicative environment with positive interdependence and interaction, where knowledge is shared by students questioning and challenging each other. Consequently, the teacher’s role in setting communicative norms which encourage an environment of high acceptance, where students feel that they can express their opinions freely, is of utmost importance. The results suggest that there are two important factors that affect student activity in the initial stages of an online course: how much the teacher communicates with the class and the manner in which he or she does so.
