- Objective Cerebrospinal fluid (CSF) markers of neurodegeneration [neurofilament light chain (NFL), total Tau (T-Tau)], tau pathology [phosphorylated tau (p-Tau)], glial cell damage or activation [glial fibrillary acidic protein (GFAP)], and brain amyloidosis [β-amyloid 1-42 (Aβ42)] are useful for diagnosis and prognosis in several neurodegenerative disorders. In this paper we investigate these markers and their relationship to key clinical milestones in patients with advanced Parkinson´s disease (PD) operated at our center with subthalamic nucleus deep brain stimulation (STN-DBS) for at least 15 years ago. Patients and methods Retrospective analysis of available cerebrospinal fluid and clinical data in PD-patients, 15 years or more after they underwent STN-DBS surgery. All PD-patients implanted with STN-DBS at Sahlgrenska University Hospital before January 1, 2001, were regularly assessed until January 10, 2018, or until death, or until lost to follow-up. Results Twenty three PD patients were operated with STN-DBS. Sixteen of these (six females and ten males) underwent at least one lumbar puncture (LP) immediately prior to or after STN-DBS. Their age at the latest available LP was 64 (55–75) years [median (range)], PD duration 20 (11–33) years, and Hoehn & Yahr (H&Y) stage 3 (2–4). Time between DBS operation and the last LP was 4.5 (0.3–10.8) years. Time from the last LP to the last follow up was 6 (0.1–18) years, and for the entire cohort 115 person-years. On January 10, 2018, four PD-patients (25%) were still alive. All preoperative CSF marker levels were normal. Between two days and six months after DBS, NFL and GFAP levels increased sharply but they normalized thereafter in most patients, and were normal up to almost 11 years after neurosurgery. Over time, all patients deteriorated slowly. At the last follow up, H&Y was 5 (3–5) and 12/16 were demented. There was no significant correlation between postoperative (> 6 months) CSF NFL, GFAP, T-Tau, p-Tau, β-amyloid levels and the presence of dementia, psychosis, inability to walk or need for nursing home at the time for LP, nor for presence of dementia at the last follow up or for death as of January 10, 2018. Conclusion CSF protein biomarkers remain normal despite long PD duration, severe disability, and chronic STN-DBS. They cannot be used for PD staging or prognostication but may indicate brain damage caused by other pathological factors.

- Objective: Subthalamic nucleus deep brain stimulation (STN-DBS) is an effective treatment for motor fluctuations in Parkinson's disease (PD), but does not halt disease progression. The long-term deterioration of key functions such as cognition, speech, ability to swallow, gait, urinary bladder control, orientation and reality perception is decisive for patients' independency in daily life. In this paper we investigated patients with advanced PD operated at our center with STN-DBS for at least 15 years ago, in respect to key clinical milestones reflecting their overall function in daily living. Patients and methods: Retrospective analysis of clinical data concerning key clinical milestones including death in PD-patients, 15 years or more after they underwent STN-DBS surgery. All PD-patients implanted with STN-DBS at Sahlgrenska Hospital before January 1, 2001, were regularly assessed until death, dropout, or January 11, 2016. Results: Sixteen men and seven women with a median (range) disease duration of 18 (10-28) years were operated with STN-DBS. The median (range) follow-up time post-surgery was 12 (2-18) years and 692 person-years of disease duration were observed. In January 2016, nine PD-patients (39%) were still alive (eight with active STN-DBS). Initially, motor symptoms improved in all patients. Sustained benefit (implying active stimulation at the last follow up) was maintained in 19 of them (83%) but STN-DBS was inactivated in four (17%) due to inefficacy. Over time, all patients deteriorated slowly, and a majority developed severe non-motor and axial symptoms such as dementia, inability to talk, swallow and walk, urinary incontinence, psychosis, and need for nursing home care. At the last follow up, 16/23 (70%) patients were treated with antidepressants. Conclusion: A majority of PD-patients experience sustained motor benefit with continuous STN-DBS. However, over time, non-motor and axial symptoms slowly and severely restrict PD-patients' function in their daily living. (C) 2017 Elsevier B.V. All rights reserved.

The Barcelona/Karlstad Study : A Comparative Study of Female Nursing Staff

Tidskriftsartikel (refereegranskat)abstract
- The aim of this descriptive and exploratory study was to compare the female nursing staffs subjectivily experienced health and well-beeing in two different types of welfare system. This is achieved through demonstrating the possible differences between Swedish and Spanish female nursing staff with regard to living environment, health and satisfaction with general social conditions. For data collection we used a questionnaire answered by 293 nurses and assistant nurses in Spain and 464 in Sweden. The results show significant differences in health. In all aspects Sweedish women experience a better health situation. For Spanish women dissatisfaction with their work situation and leisure is strongly significant and correlates negatively with their health. For Swedish women dissatisfaction with home and family situation, social intercourse, work situation and leisure has a negative influence on their health.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This paper is a presentation of a pilot-study where DMT is used as an alternative treatment for young boys with the diagnosis ADHD. The aim of the study is to investigate and evaluate DMT for young boys with aggressive and destructive behaviour - symptoms related to ADHD. Thereby focusing physical as well as mental and socio-emotional changes. It is a multi-disciplinary project with researches from two different areas. The project is a cooperation between the University College of Dance in Stockholm, the Department of Public Health at Karlstad University and the Clinical Department of Child and Adolescent Psychiatry in Karlstad. The project took place at BUP, Karlstad, during 2001-2004. This pilot-study will be presented in a report from the University College of Dance in June 2004. The final report will come in September 2005
