- Recent work by Siegelmann has shown that the computational power of recurrent neural networks matches that of Turing Machines. One important implication is that complex language classes (infinite languages with embedded clauses) can be represented in neural networks. Proofs are based on a fractal encoding of states to simulate the memory and operations of stacks. In the present work, it is shown that similar stack-like dynamics can be learned in recurrent neural networks from simple sequence prediction tasks. Two main types of network solutions are found and described qualitatively as dynamical systems: damped oscillation and entangled spiraling around fixed points. The potential and limitations of each solution type are established in terms of generalization on two different context-free languages. Both solution types constitute novel stack implementations—generally in line with Siegelmann's theoretical work—which supply insights into how embedded structures of languages can be handled in analog hardware.

Tidskriftsartikel (refereegranskat)abstract
- A study was performed to describe and compare pain and Health-Related Quality of Life (HRQOL) in two groups of cancer patients in palliative care as well as to describe the correlation between pain and HRQOL. ○ Forty-seven patients with mild average pain [Visual Analogue Scale (VAS) < 3] and 28 patients with moderate to severe average pain (VAS > 3) were included. Medical Outcomes Study Short Form (SF-36) was used to evaluate HRQOL, pain intensity levels were measured with the VAS on Pain-O-Meter. ○ Compared to patients with mild pain, patients with moderate to severe pain had statistically significant, higher pain intensity for the items 'pain at time of interview', 'worst pain in the past 24 hours' and 'pain interrupting sleep.' They also had the lowest scores of the SF-36 dimensions: physical functioning, role-physical, and bodily pain. Patients with moderate to severe pain had statistically significant, fewer months of survival. There were statistically significant positive correlations between pain items and negative correlation between pain and SF-36 dimensions. ○ The conclusion is that pain has a negative impact on HRQOL, especially on physical health and that pain increases towards the final stages of life. Even if patients have to endure symptoms such as fatigue and anxiety during their short survival time, dealing with pain is an unnecessary burden, which can be prevented.

Acute postoperative and cancer-related pain management, Patients´ experiences and perceptions in relation to health-related quality of life and the multidimensionality of pain
- 2003

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis describes patients in acute postoperative pain as well as patients with acute cancer-related pain in palliative care, and their experiences and perceptions of pain management in relation to HRQOL and the multidimensionality of pain. A combination of qualitative and quantitative methods was chosen. Data were collected using interviews and questionnaires; APS, SF:36 and a new developed questionnaire PC-PPQ measuring care related to pain management in palliative care. For assessing pain VAS and Pain-o-Meter were used. The study group consisted of 100 patients on their second postoperative day, and of 75 patients with cancer-related pain from two palliative care teams. The result showed that at the time of the interview 29 of the patients with postoperative pain reported a pain > 3 on VAS and 79 reported VAS > 3 as worst pain past 24 hours. The higher the intensity of pain the less satisfied the postoperative patients were with the nurses´ way of treating their pain. Thirty-three patients stated that they had received information regarding the importance of pain relief. Patients with postoperative pain as well as patients with cancer-related pain had been prescribed analgesics mostly a combination of Paracetamol, NSAID and opioid. Of the 75 patients with cancer-related pain and in palliative care 22 patients reported pain >3 on POM-VAS and 47 patients reported >3 on POM-VAS as worst pain past 24 hours. Twenty-eight patients reported an average pain > 3 on POM-VAS past 24 hours. Twenty-four patients used the words troublesome or tiring when describing their affective pain. Sensory pain was described as prickling or sore by 15 patients. The patients perceived their pain as “aching all over” and expressed a wish for pain relief as well as a fear for increased pain. HRQOL especially physical functioning decreased for patients with average pain > 3. Being cared for by a nurse-led or a physician-led palliative care team indicated no statistically significant differences for patients´ HRQOL or pain intensities. The patients had experienced a statistically significant better care after being referred to a palliative care team, despite that pain control had not been optimized. Patients expressed a need for communication, planning and trust in order to improve pain management. Continuity of care and the opportunity to talk increase the patients feeling of security, as well as improved their perceived pain control. Structured ongoing discussion concerning pain management from an early stage of the disease or already preoperatively can provide an important intervention to meet the results of this thesis. Pain assessment covering the multidimensionality of pain, and pain treatment plans including both pharmacological and non-pharmacological treatment are further important interventions.

Tidskriftsartikel (refereegranskat)abstract
- A two-centred descriptive study was performed in order to describe and compare pain and health-related quality of life (HRQOL) among cancer patients, in their final stage of life. The patients were cared for by either a nurse-led palliative care team I (PCT I) or a physician-led palliative care team II (PCT II). Forty-six consecutive, stratified patients (PCT I, n = 21 and PCT II, n = 25) participated. The medical outcomes study short form 36 (SF-36) was used for evaluating HRQOL and the Pain-O-Meter for assessing pain. Patients' pain intensity, pain quality and HRQOL showed no significant difference between the two groups PCT I and PCT II. The patients from PCT I had significantly longer survival time (P = 0.017) than those from PCT II. The different composition of the teams being led by nurses or physicians is worth further research; both from the patient's and staff's viewpoint, there may also be cost-benefits worth examining.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Patients with inflammatory joint diseases tend due to new treatments to be more physically active; something not taken into account by currently used outcome measures. The Rheumatoid and Arthritis Outcome Score (RAOS) is an adaptation of the Knee injury and Osteoarthritis Outcome Score (KOOS) and evaluates functional limitations of importance to physically active people with inflammatory joint diseases and problems from the lower extremities. The aim of the study was to test the RAOS for validity, reliability and responsiveness. METHODS: 119 in-patients with inflammatory joint disease (51% RA) admitted to multidisciplinary care, mean age 56 (+/-13), 73% women, mean disease duration 18 (+/-14) yr were consecutively enrolled. They all received the RAOS, the SF-36, the HAQ and four subscales of the AIMS2 twice during their stay for test of validity and responsiveness. Test-retest reliability of the RAOS questionnaire was calculated on 52 patients using the first or second administration and an additional mailed questionnaire. RESULTS: The RAOS met set criteria of reliability and validity. The random intraclass correlation coefficient (ICC 2,1) for the five subscales ranged from 0.76 to 0.92, indicating that individual comparisons were possible except for the subscale Sport and Recreation Function. Inter-item correlation measured by Cronbach's alpha ranged from 0.78 to 0.95. When measuring construct validity the highest correlations occurred between subscales intended to measure similar constructs. Change over time (24 (+/- 7) days) due to multidisciplinary care was significant for all subscales (p < 0.001). The effect sizes ranged from 0.30-0.44 and were considered small to medium. All the RAOS subscales were more responsive than the HAQ. Some of the SF-36 subscales and the AIMS2 subscales were more responsive than the RAOS subscales. CONCLUSION: It is possible to adapt already existing outcome measures to assess other groups with musculoskeletal difficulties in the lower extremity. The RAOS is a reliable, valid and responsive outcome instrument for assessment of multidisciplinary care. To fully validate the RAOS further studies are needed in other populations.

- Sleep related breathing disorders are common as well as a poor prognostic sign associated with higher mortality in patients with congestive heart failure (CHF). These patients often have a shorter total duration of sleep, disturbed sleep structure and increased daytime sleepiness, which can negatively affect all dimensions of the life situation. The spouse has an important role in supporting the patient in relation to sleep disorders, but this role may be adversely affected by the sleep situation of the couple. The aim of this study was to describe decisive situations that influence spouses' support to patients with CHF in relation to the couple's sleep situation. A qualitative descriptive design using critical incident technique was employed. Incidents were collected by means of interviews with 25 spouses of patients with CHF, strategically selected from two hospital-based specialist clinics in southern Sweden. Two main areas emerged in the analysis: support stimulating situations and support inhibiting situations. Support stimulating situations described how spouses' support was positively affected by their own adaptation in psychosocial or practical situations, and receiving help from others. Support inhibiting situations described how the spouses' support was negatively affected by sleep disturbances as a result of the patient's symptoms, anxiety in relation to the disease, limitations as a result of the sleeping habits, dissatisfaction with care related to the sleep situation, and being left to cope alone with the problems. An increased understanding of the stimulating and inhibiting situations influencing spouses' support for patients with CHF can guide health care personnel in deciding if an intervention is needed to improve the sleep situation for patient and spouse.
