- Purpose The overall objective in this study is to investigate the early development of radiographic knee osteoarthritis (OA) and its association with hand or/and knee OA, metabolic diseases, biomarkers, chronic pain, physical function and daily physical activity types. Participants The Halland osteoarthritis (HALLOA) cohort is a longitudinal cohort study that includes individuals with knee pain in the southwest of Sweden. Enrolment took place from 2017 to 2019. The inclusion criteria were current knee pain, with no former known radiographic knee OA and no cruciate ligament rupture or rheumatological disorder. The participants were recruited: (1) when seeking care for knee pain in primary healthcare or (2) by advertisements in local newspapers. There are 306 individuals included in the study, mean age (SD) 51.7 (8.7) years and 69% are women. The baseline and follow-ups include clinical tests, radiographical examinations, blood samples, metabolic measures, pain pressure thresholds, tests of physical functions, daily physical activity types and patient-reported outcomes. Findings to date There were associations between metabolic factors and radiographic knee OA, even in those with normal body mass index at baseline. In addition, clinical hand OA was positively associated with fasting plasma glucose. We also found that modifiable factors as increased visceral fat and total body fat were associated with increased pain sensitivity among individuals with knee pain. Future plans By studying possible pathophysiological mechanisms of OA over time, we aim to provide new insights on OA progression, identify usable preventive measures helping the clinicians in the management of the disease and improve health for the patients. It is also important to study the development of chronic pain in OA, to get tools to identify individuals at risk and to be able to offer them treatment.

- BACKGROUND: With an increasing number of patients with osteoarthritis (OA) and rheumatoid arthritis (RA) in primary care, our aim was to investigate arthritis-related practice in physiotherapy and to study adherence to evidence-based care.METHODS: Seventy physiotherapists (PTs) working in primary care were emailed a questionnaire to investigate current practice and the number of roles assumed by PTs, the degree of confidence, educational needs and adherence to national guidelines in managing patients with OA or RA. Interventions supported by national guidelines were compared with reports of treatment modalities in the questionnaire.RESULTS: Sixty-four (91%) PTs responded, and they reported a higher degree of confidence in assessment, treatment and education of patients with OA than for those with RA (p < 0.001). The total number of roles assumed by the PTs was higher in the management of OA than for RA (p < 0.001). PTs who assumed a greater number of roles also reported a stronger degree of confidence in assessing OA (p = 0.036). Those who assumed fewer roles also reported less confidence in RA treatment (p = 0.045). Recommendations in the guidelines were followed by the majority of PTs for eight of 11 treatment modalities in OA and for six of six in RA.CONCLUSIONS: PTs reported a lower degree of confidence and the assumption of fewer roles in managing patients with RA compared with OA. There was good adherence to the national guidelines for almost all the treatment modalities listed. Even so, the results indicate a need for education, especially in chronic inflammatory arthritis care.

Patients treated for psychosis and their perceptions of care in compulsory treatment : basis for an action plan
- 2012
-

Tidskriftsartikel (refereegranskat)abstract
- The purpose of the study was to describe patients' conceptions and experiences of care in compulsory treatment for acute onset of psychosis. Twelve patients with experience of compulsory treatment were interviewed in 2008-2009, and phenomenographic analysis was used to analyse the data. Two descriptive categories emerged in the results: receiving needed support and perceiving respectful care. Patients perceived that coercive interventions were positive if they were given good care, if they were given the shelter they needed, if they got help with understanding and if the setting was healing. Patients felt respected if they were treated like human beings, if they were allowed to retain as much of their autonomy as possible and if they were invited to participate even though they were under compulsory treatment. The results show that it is important to prevent patients from being traumatized during compulsory treatment and to take advantage of patients' inner resources. Patients' experiences of compulsory treatment can form the basis for preparing an individual action plan for future compulsory treatment. Individual action plans could empower patients during compulsory treatment and improve their experience of care.

- Regular physical exercise/activity has been shown repeatedly to promote positive benefits in cognitive, emotional and motor domains concomitant with reductions in distress and negative affect. It exerts a preventative role in anxiety and depressive states and facilitates psychological well-being in both adolescents and adults. Not least, several meta-analyses attest to improvements brought about by exercise. In the present treatise, the beneficial effects of exercise upon cognitive, executive function and working memory, emotional, self-esteem and depressed mood, motivational, anhedonia and psychomotor retardation, and somatic/physical, sleep disturbances and chronic aches and pains, categories of depression are discussed. Concurrently, the amelioration of several biomarkers associated with depressive states: hypothalamic-pituitary-adrenal (HPA) axis homeostasis, anti-neurodegenerative effects, monoamine metabolism regulation and neuroimmune functioning. The notion that physical exercise may function as "scaffolding" that buttresses available network circuits, anti-inflammatory defences and neuroreparative processes, e.g. brain-derived neurotrophic factor (BDNF), holds a certain appeal. © 2014 Bentham Science Publishers.

- © Author(s) 2019. Aims: The aim of this study was to investigate the prevalence of cybervictimization in the six Nordic countries and to assess its overlap with traditional bullying. A further aim was to examine potential associations between life satisfaction, on the one hand, and traditional bullying and cyberbullying on the other. Methods: Analyses were based on data from the 2013⁄2014 Health Behaviour in School-aged Children study. It included 32,210 boys and girls, aged 11, 13, and 15, living in the six Nordic countries. Results: The prevalence of cyberbullying by both pictures and by messages was around 2% in all the Nordic countries except Greenland. There it was considerably higher. The prevalence of being bullied in a traditional manner varied widely by country. For boys, this type of bullying was most frequent in the youngest age group and then decreased steadily in the older age groups. Girls were on average more likely to be cyberbullied. Cyberbullying was more common among 13- and 15-year-olds than 11-year-olds. Higher family affluence was unrelated to the risk of cyberbullying. However, it was related to traditional bullying and combined forms of bullying. Compared with intact families, cybervictimization was commoner among single-parent families and stepfamilies. Adjusting for age, gender, family affluence, and family structure, those subjected to cyberbullying had lower life satisfaction than those who were not bullied. Conclusions: We found relatively little overlap between cyberbullying and traditional bullying, indicating that the two may be separate phenomena stemming from different mechanisms, at least in the Nordic context.

Attribute-based encryption with enforceable obligations
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Attribute-based encryption (ABE) is a cryptographic mechanism that provides fine-grained access control to encrypted data, which can thus be stored in, e.g., public clouds. However, ABE schemes lack the notion of obligations, which is common in attribute-based access control systems such as eXtensible Access Control Markup Language and Usage Control. Obligations are used to define and enforce extra constraints that happen before approving or denying an access request. In this paper, we propose OB-ABE, a system for extending any classical ABE with enforceable obligations. Our system architecture has as core component trusted hardware enclaves, implemented with SGX, used for enforcing obligations. We employ ProVerif to formally model OB-ABE and verify its main property called "enforceable obligations," i.e., if a message is encrypted along with an obligation, then the message can be decrypted only after enforcing the attached obligation. OB-ABE has two more properties: (i) OB-ABE is a "conservative extension" of the underlying ABE scheme, preserving its security properties; (ii) OB-ABE is "backward compatible" in the sense that any ciphertext produced by an ABE scheme can be decrypted by its extended OB-ABE version, and moreover, a ciphertext produced by an OB-ABE scheme can be decrypted by its underlying ABE scheme provided that the ciphertext does not have obligations attached. We also implement in C using Intel SGX a prototype of an OB-ABE extending the well-known ciphertext-policy ABE.

Effects of process-oriented group supervision as reported by nursing students : a pilot study
- 2008
-
Ingår i: Vård i Norden. - Köpenhamn : SSN [Sjuksköterskornas samarbete i Norden]. - 0107-4083 .- 1890-4238. ; 28:1, s. 26-29

- One method to ensure that nursing students are better prepared for their future professional role can be to offer them process-oriented group supervision. The aim of this prospective, longitudinal pilot study was to evaluate the effects of a process-oriented group supervision programme (PGSP) comprising educational, supportive and developmental areas based on reports by nursing students undergoing a 3-year nursing education. The students (N=61) evaluated their experiences of the PGSP by means of a questionnaire, which they filled in after each study year. An independent t-test was conducted to compare the educational, supportive, and developmental areas after the first (2002), second (2003) and third year (2004) as well as over the whole 3-year study period. The result showed no significant difference in scores in the educational area. However, there was a significant increase in the supportive area (p=.03) over the 3-year period, which was especially noticeable during the first year (p=.013). There was also an increase in the developmental area over the 3-year period (p=.021) as well as during the first year (p=.024). Thus, PGSP seems to develop nursing students in their professional identity and personal growth. However, as this was a pilot study, a research implication is to perform a large-scale study over a longer period of time.

- Aim: The aim was to describe variations in how doctoral students conceive their learning process to become researchers in the light of their professional background as nurses. Background: Nursing research is an emerging discipline and the number of nurses who acquire a doctor's degree is increasing. Method: The study had a descriptive, qualitative design with a phenomenographic approach and was carried out by means of 20 interviews. Results: Three different description categories emerged: (1) A learning process that provides a synthesis of different parts of the research process aimed at developing preparedness for action within the nursing profession. (2) A learning process where practical problems are integrated with and problematised in relation to scientific theories. (3) A learning process involving the transformation from nurse to researcher. Conclusions: The description categories revealed that the focus was on solving problems that occur in health care and synthesising them by means of research tools. Furthermore, the doctoral students explored different ways of understanding and developing their awareness of the nature of research. Focus was also on the nursing profession and practice and a shift towards the role of a researcher was evident. © 2012 Elsevier Ltd.

- AIM: To describe the variation in how nurses conceive process-oriented group supervision, implemented during nursing education, 1 year after their nursing degree. BACKGROUND: Process-oriented group supervision can be an effective support system for helping nursing students and nurses to reflect on their activities. METHODS: A descriptive qualitative design was chosen for the study. Conceptions were collected through interviews with 18 strategically selected Swedish nurses in 2005. RESULTS: Three descriptive categories comprising seven conceptions were emerged. Supportive actions comprised: a sense of security, belonging and encouragement. Learning actions involved: sharing and reflecting while developmental actions described: enabling professional identity and facilitating personal development. CONCLUSIONS: Process-oriented group supervision has a lasting influence on nurses' development. The possibility to reflect over new stances during nursing education was a prerequisite for the provision of high-quality care. Process-oriented group supervision can make an important contribution to nursing education. IMPLICATIONS: for Nursing Management Process-oriented group supervision provides nurses with the strength to achieve resilience to stress in their work. It may lead to autonomy as well as clarity in the nurse's professional function. This indicates the need for nurse managers to organize reflective group supervision as an integral part of the nurse's work.

The development of a questionnaire for evaluating process-oriented group supervision during nursing education
- 2008

- The benefits of process-oriented group supervision are difficult to evaluate, as the validity and reliability of the existing instruments have been questioned. The aim was to develop and test the psychometric properties of a questionnaire in order to evaluate the effects of process-oriented group supervision on nursing students during their three-year nursing education. A 55-item Process-oriented Group Supervision Questionnaire (PGSQ) with a developmental design was formulated on the basis of a literature review and the expectations of nursing students who participated in a three-year nursing education programme (N = 176). Construct validity and internal consistency reliability were tested at the end of each study year: year 1 (T1), year 2 (T2), and year 3 (T3) by means of exploratory factor analysis and Cronbach’s coefficient. An adequate explorative factor analysis (principal component analysis, varimax rotation) with an Eigenvalue >1.0 and factor loadings >0.40, reduced the questionnaire to 18 items comprising three factors labelled educative, supportive and developmental, which explained 60.2% at T1, 71.8% at T2, and 69.3% at T3 of the total cumulative variance. The corresponding Cronbach’s coefficient figures were 0.89 (T1), 0.94 (T2) and 0.93 (T3). The 18-item PGSQ is considered to be a short and useful tool due to its satisfactory validity and reliability figures.
