Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- It has been shown (Franck Pettersen, Master thesis 1995) that a planetarium show has a much larger educational impact if it is accompanied by hands-on experimenting. In the present paper, a number of interactive exhibits that we have used together with Stella Nova Planetarium at Falun Science Center and at Teknoland are presented.

Severe Lung Dysfunction and Pulmonary Blood Flow during Extracorporeal Membrane Oxygenation

Tidskriftsartikel (refereegranskat)abstract
- Background: Extracorporeal membrane oxygenation (ECMO) is indicated for patients with severe respiratory and/or circulatory failure. The standard technique to visualize the extent of pulmonary damage during ECMO is computed tomography (CT). Purpose: This single-center, retrospective study investigated whether pulmonary blood flow (PBF) measured with echocardiography can assist in assessing the extent of pulmonary damage and whether echocardiography and CT findings are associated with patient outcomes. Methods: All patients (>15 years) commenced on ECMO between 2011 and 2017 with septic shock of pulmonary origin and a treatment time >28 days were screened. Of 277 eligible patients, 9 were identified where both CT and echocardiography had been consecutively performed. Results: CT failed to indicate any differences in viable lung parenchyma within or between survivors and non-survivors at any time during ECMO treatment. Upon initiation of ECMO, the survivors (n = 5) and non-survivors (n = 4) had similar PBF. During a full course of ECMO support, survivors showed no change in PBF (3.8 ± 2.1 at ECMO start vs. 7.9 ± 4.3 L/min, p = 0.12), whereas non-survivors significantly deteriorated in PBF from 3.5 ± 1.0 to 1.0 ± 1.1 L/min (p = 0.029). Tidal volumes were significantly lower over time among the non-survivors, p = 0.047. Conclusions: In prolonged ECMO for pulmonary septic shock, CT was not found to be effective for the evaluation of pulmonary viability or recovery. This hypothesis-generating investigation supports echocardiography as a tool to predict pulmonary recovery via the assessment of PBF at the early to later stages of ECMO support.

- To investigate whether total sleep deprivation (TSD) affects circulating concentrations of neuron-specific enolase (NSE) and S100 calcium binding protein B (S-100B) in humans. These factors are usually found in the cytoplasm of neurons and glia cells. Increasing concentrations of these factors in blood may be therefore indicative for either neuronal damage, impaired blood brain barrier function, or both. In addition, amyloid β (Aβ) peptides 1-42 and 1-40 were measured in plasma to calculate their ratio. A reduced plasma ratio of Aβ peptides 1-42 to 1-40 is considered an indirect measure of increased deposition of Aβ 1-42 peptide in the brain.

- Objective. The most effective nonpharmacological treatment for insomnia disorder is cognitive behavioural therapy-insomnia (CBT-i). However CBT-i may not suit everyone. Auricular acupuncture (AA) is a complementary treatment. Studies show that it may alleviate insomnia symptoms. The aim of this randomised controlled study was to compare treatment effects of AA with CBT-i and evaluate symptoms of insomnia severity, anxiety, and depression. Method. Fifty-nine participants, mean age 60.5 years (SD 9.4), with insomnia disorder were randomised to group treatment with AA or CBT-i. Self-report questionnaires, the Insomnia Severity Index (ISI), Dysfunctional Beliefs and Attitudes about Sleep scale (DBAS-16), Epworth Sleepiness Scale (ESS), and Hospital Anxiety and Depression scale (HAD), were collected at baseline, after treatment, and at 6-month follow-up. A series of linear mixed models were performed to examine treatment effect over time between and within the groups. Results. Significant between-group improvements were seen in favour of CBT-i in ISI after treatment and at the 6-month follow-up and in DBAS-16 after treatment. Both groups showed significant within-group postintervention improvements in ISI, and these changes were maintained six months later. The CBT-i group also showed a significant reduction in DBAS-16 after treatment and six months later. Conclusions. Compared to CBT-i, AA, as offered in this study, cannot be considered an effective stand-alone treatment for insomnia disorder.

Auricular acupuncture for insomnia

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Cognitive behavioural therapy for insomnia (CBT-i) is the most effective treatment for insomnia. Studies show that auricular acupuncture (AA) may alleviate insomnia symptoms.The overall aim of the thesis was to compare treatment effects of auricular acupuncture (AA) with cognitive behavioural therapy for insomnia (CBT-i) on symptoms of insomnia, anxiety, depression, hypnotic drugs consumption and quality of life from short- and long-term perspectives.Paper I had a qualitative approach with a descriptive design. 16 participants received group-treatment with AA during their protracted withdrawal phase and were interviewed about their experiences. They participants experienced a reduction in protracted withdrawal symptoms, improved subjective sleep quality, a strong sensation of peacefulness and increased wellbeing.Paper II, III and IV present results from a randomised controlled trial in where the effects of group-treatment with AA and CBT-i were compared in short- and long-term using subjective (questionnaires and sleep diary) and objective (actigraphy) measurements.The results showed that CBT-i was superior to AA in reducing insomnia symptoms in both the short and long run. Both groups experienced significant long-term reduction of depressive symptoms. Further, both groups managed to maintain a decreased intake of hypnotic drugs at the end of the treatment when compared to baseline measurement. Short-term reduction of symptoms of anxiety and depression improved only in the AA group. The results from the objective actigraph recordings showed that the AA group slept more and the CBT-i group less after the treatment and that sleep patterns in both groups reverted to pre-treatment levels after 6 months.Conclusively: AA, as administered in this study, was not as good as CBT-i in treating insomnia symptoms, and should not be used as a stand-alone treatment for insomnia. Our results also demonstrate that prolonged sleep time does not necessarily yield better sleep, and that the perception of insomnia symptoms is not inevitably affected by sleep duration. AA was as effective as CBT-i in ending hypnotic drugs consumption. Moreover, AA was more successful than CBT-i in reducing symptoms of anxiety and depression in the short run. Further studies investigating AA for anxiety and depression are motivated.
