  • In: Dementia and geriatric cognitive disorders. - : S. Karger AG. - 1421-9824 .- 1420-8008. ; 31:2, s. 132-8
  • Journal article (peer-reviewed)abstract
    • Mild cognitive impairment (MCI) is a heterogeneous condition suggested as a prodromal state of Alzheimer's disease (AD) and subcortical vascular dementia (SVD). Recent findings suggest that white matter lesions (WML) may be associated with hippocampal atrophy. The objective of the study was to examine hippocampal and WML volumes in MCI patients and to examine if WML were linked to hippocampal atrophy.

  • Longitudinal evaluation of criteria for subjective cognitive decline and preclinical Alzheimer's disease in a memory clinic sample.
  • 2017
  • In: Alzheimer's & Dementia. - : Wiley. - 1552-5260 .- 1552-5279. ; 16:8, s. 96-107
  • Journal article (peer-reviewed)abstract
    • Subjective cognitive decline (SCD) and biomarker-based "at-risk" concepts such as "preclinical" Alzheimer's disease (AD) have been developed to predict AD dementia before objective cognitive impairment is detectable. We longitudinally evaluated cognitive outcome when using these classifications.Memory clinic patients (n=235) were classified as SCD (n=122): subtle cognitive decline (n=36) and mild cognitive impairment (n=77) and subsequently subclassified into SCDplus and National Institute on Aging-Alzheimer's Association (NIA-AA) stages 0 to 3. Mean (standard deviation) follow-up time was 48 (35) months. Proportion declining cognitively and prognostic accuracy for cognitive decline was calculated for all classifications.Among SCDplus patients, 43% to 48% declined cognitively. Among NIA-AA stage 1 to 3 patients, 50% to 100% declined cognitively. The highest positive likelihood ratios (+LRs) for subsequent cognitive decline (+LR 6.3), dementia (+LR 3.4), and AD dementia (+LR 6.5) were found for NIA-AA stage2.In a memory clinic setting, NIA-AA stage 2 seems to be the most successful classification in predicting objective cognitive decline, dementia, and AD dementia.

  • Consensus guidelines for lumbar puncture in patients with neurological diseases
  • 2017
  • In: Alzheimer's and Dementia: Diagnosis, Assessment and Disease Monitoring. - : Wiley. - 2352-8729. ; 8, s. 111-126
  • Journal article (peer-reviewed)abstract
    • Introduction Cerebrospinal fluid collection by lumbar puncture (LP) is performed in the diagnostic workup of several neurological brain diseases. Reluctance to perform the procedure is among others due to a lack of standards and guidelines to minimize the risk of complications, such as post-LP headache or back pain. Methods We provide consensus guidelines for the LP procedure to minimize the risk of complications. The recommendations are based on (1) data from a large multicenter LP feasibility study (evidence level II-2), (2) systematic literature review on LP needle characteristics and post-LP complications (evidence level II-2), (3) discussion of best practice within the Joint Programme Neurodegenerative Disease Research Biomarkers for Alzheimer's disease and Parkinson's Disease and Biomarkers for Multiple Sclerosis consortia (evidence level III). Results Our consensus guidelines address contraindications, as well as patient-related and procedure-related risk factors that can influence the development of post-LP complications. Discussion When an LP is performed correctly, the procedure is well tolerated and accepted with a low complication rate.

  • Cost-effectiveness of lumbar fusion and nonsurgical treatment for chronic low back pain in the Swedish lumbar spine study : A multicenter, randomized, controlled trial from the Swedish Lumbar Spine Study Group
  • 2004
  • In: Spine. - : Lippincott Williams & Wilkins. - 0362-2436 .- 1528-1159. ; 29:4, s. 421-434
  • Journal article (peer-reviewed)abstract
    • Study Design. A cost-effectiveness study was performed from the societal and health care perspectives. Objective. To evaluate the costs-effectiveness of lumbar fusion for chronic low back pain (CLBP) during a 2-year follow-up. Summary of Background Data. A full economic evaluation comparing costs related to treatment effects in patients with CLBP is lacking. Patients and Methods. A total of 284 of 294 patients with CLBP for at least 2 years were randomized to either lumbar fusion or a nonsurgical control group. Costs for the health care sector ( direct costs), and costs associated with production losses ( indirect costs) were calculated. Societal total costs were identified as the sum of direct and indirect costs. Treatment effects were measured using patient global assessment of improvement, back pain ( VAS), functional disability (Owestry), and return to work. Results. The societal total cost per patient ( standard deviations) in the surgical group was significantly higher than in the nonsurgical group: Swedish kroner (SEK) 704,000 ( 254,000) vs. SEK 636,000 ( 208,000). The cost per patient for the health care sector was significantly higher for the surgical group, SEK 123,000 ( 60,100) vs. 65,200 ( 38,400) for the control group. All treatment effects were significantly better after surgery. The incremental cost-effectiveness ratio ( ICER), illustrating the extra cost per extra effect unit gained by using fusion instead of nonsurgical treatment, were for improvement: SEK 2,600 ( 600 - 5,900), for back pain: SEK 5,200 ( 1,100 - 11,500), for Oswestry: SEK 11,300 ( 1,200 - 48,000), and for return to work: SEK 4,100 ( 100 21,400). Conclusion. For both the society and the health care sectors, the 2-year costs for lumbar fusion was significantly higher compared with nonsurgical treatment but all treatment effects were significantly in favor of surgery. The probability of lumbar fusion being cost-effective increased with the value put on extra effect units gained by using surgery.

  • Interleukin-13 inhibits cell proliferation and stimulates interleukin-6 formation in isolated human osteoblasts.
  • 1998
  • In: The Journal of clinical endocrinology and metabolism. - 0021-972X. ; 83:9, s. 3285-9
  • Journal article (peer-reviewed)abstract
    • Interleukin-13 (IL-13) is a recently identified cytokine that is secreted by activated T cells and regulates inflammatory responses. We have investigated the effects of IL-13 on isolated human osteoblast-like cells (hOB). IL-13 dose-dependently (1-100 pmol/L) reduced the incorporation rate of [3H]thymidine in hOB cells by more than 50%. Using a cell metabolic assay as well as direct cell counting, we found that treatment with IL-13 lead to a decrease in hOB cell number. The effect was both time and dose dependent, and after 12 days of culture, treatment with IL-13 (0.1 nmol/L) caused a 70% decrease in the number of cells. Also, IL-13 increased the levels of IL-6 messenger ribonucleic acid in hOBs, as measured by ribonuclease protection assay, and stimulated secretion of IL-6 into culture supernatants. In conclusion, IL-13 inhibits cell proliferation and increases IL-6 formation in human osteoblasts. Our findings suggest that IL-13 may cause bone loss due to impaired osteoblastic growth and IL-6-induced osteoclast recruitment.

  • Effects of an Empowerment-Based Health-Promotion School Intervention on Physical Activity and Sedentary Time among Adolescents in a Multicultural Area
  • 2018
  • In: International Journal of Environmental Research and Public Health. - Basel : MDPI. - 1661-7827 .- 1660-4601. ; 15:11
  • Journal article (peer-reviewed)abstract
    • Physical activity (PA) decreases with age, and interventions are needed to promote PA during adolescence, especially, among those in low-socioeconomic status (SES) areas. The aim of this study was to investigate whether a two-year, empowerment-based health-promotion school intervention had any effects on changes in (a) moderate-to-vigorous PA (MVPA), (b) sedentary time (SED), (c) exercise training (ET) frequency, and (d) ET duration, among adolescents. Participants (aged 12-13 years at baseline) from one intervention school and two control schools, were recruited from a multicultural area of Sweden, characterized by low-SES. During the course of the two-year intervention, a total of 135 participants (43% boys) were included in the study. The intervention was developed and implemented as a result of cooperation and shared decision-making among the researchers and the participants. MVPA and SED were measured with accelerometers, and ET frequency and duration was self-reported at the beginning of the seventh, eighth, and ninth grade, respectively. There were no significant effects of the two-year, empowerment-based health-promotion school intervention on changes in the accelerometer-measured MVPA and SED, or the self-reported ET frequency and duration, among the adolescents. Overall, the intervention was unsuccessful at promoting PA and reducing SED. Several possible explanations for the intervention's lack of effects are discussed.

  • Pre- and postnatal growth failure with microcephaly due to two novel heterozygous IGF1R mutations and response to growth hormone treatment
  • 2020
  • In: Acta Paediatrica. - : Wiley-Blackwell Publishing Inc.. - 0803-5253 .- 1651-2227. ; 109:10, s. 2067-2074
  • Journal article (peer-reviewed)abstract
    • AIM: To explore the phenotype and response to growth hormone in patients with heterozygous-mutations in the insulin-like growth factor I receptor gene (IGF1R).METHODS: Children with short-stature, microcephaly, born SGA combined with biochemical sign of IGF-I insensitivity were analyzed for IGF1R mutations or deletions using Sanger sequencing and Multiple ligation dependent probe amplification analysis.RESULTS: In two families, a novel heterozygous non-synonymous missense IGF1R variant was identified. In family 1, c.3364G>T, p.(Gly1122Cys) was found in the proband and co-segregated perfectly with the phenotype in three generations. In family 2, a de novo variant c.3530G>A, p.(Arg1177His) was detected. Both variants were rare, not present in the GnomAD database. Three individuals carrying IGF1R mutations have received rhGH treatment. The average gain in height SDS during treatment was 0.42 (range: 0.26 - 0.60) and 0.64 (range: 0.32 - 0.86) after 1 and 2 years of treatment, respectively.CONCLUSION: Our study presents two heterozygous IGF1R mutations causing pre- and postnatal growth failure and microcephaly and also indicates that individuals with heterozygous IGF1R mutations can respond to rhGH treatment. The findings highlight that sequencing of the IGF1R should be considered in children with microcephaly and short stature due to pre- and postnatal growth failure.

  • Partners in Crime: How Liars in Collusion Betray Themselves
  • 2003
  • In: Journal of Applied Social Psychology. - : Wiley-Blackwell Publishing, Inc.. - 0021-9029 .- 1559-1816. ; 33:4, s. 848-868
  • Journal article (peer-reviewed)abstract
    • The paradigmatic task for participants in studies on deception is to assess veracity on the basis of a single statement. However, in applied contexts, lie catchers are often faced with multiple statements (reported by one or several suspects). To appreciate this mismatch, we conducted a study where each member of 10 truth-telling pairs and 10 lying pairs (reporting fabricated alibis) was interrogated twice about an alibi. As predicted, lying pair members were more consistent between themselves than were truth-telling pair members, and single liars and truth tellers were equally consistent over time. Furthermore, truth tellers made more commissions than did liars. Although in line with our repeat vs. reconstruct hypothesis, these findings contrast sharply with beliefs held by professional lie catchers and recommendations found in literature on deception detection. The results are translated into an applied psycholegal context.
