    • Animals across phyla can detect early cues of infection in conspecifics, thereby reducing the risk of contamination. It is unknown, however, if humans can detect cues of sickness in people belonging to communities with whom they have limited or no experience. To test this, we presented Western faces photographed 2 h after the experimental induction of an acute immune response to one Western and five non-Western communities, including small-scale hunter-gatherer and large urban-dwelling communities. All communities could detect sick individuals. There were group differences in performance but Western participants, who observed faces from their own community, were not systematically better than all non-Western participants. At odds with the common belief that sickness detection of an out-group member should be biased to err on the side of caution, the majority of non-Western communities were unbiased. Our results show that subtle cues of a general immune response are recognized across cultures and may aid in detecting infectious threats.

  • A putative role for cytokines in the impaired appetite in depression
  • 2007
  • Ingår i: Brain Behavior and Immunity. - : Elsevier BV. - 1090-2139 .- 0889-1591. ; 21:2, s. 147-152

    • Impaired appetite and weight changes are commonly seen in patients with depression, but the pathophysiology behind this imbalance between energy intake and energy expenditure remains largely unknown. The aim of this paper is to review the literature regarding a possible role for cytokines in the regulation of appetite and body weight, with special emphasis on depression. There now exists a substantial amount of evidence that depressed patients show signs of immune activation including increased levels of proinflammatory cytokines. Cytokines, which by themselves have anorectic properties, stimulate the release of the cytokine-like anorexogenic peptide leptin. In addition to their anorectic properties, both proinflammatory cytokines and leptin interact with the hypothalamic-pituitary-adrenal (HPA) axis, the sympathetic nervous system (SNS) and the immune system. In turn, these systems regulate energy balance as well as they are dysfunctional in depression. Furthermore, both proinflammatory cytokines and leptin can induce anhedonia, one of the cardinal symptoms of depression. In view of the different effects on appetite and/or body weight observed in melancholic versus atypical depression, we suggest that cytokines are differentially altered in these subtypes of depression, and that this may explain some of the inconsistency in the reported findings of cytokine as well as leptin levels in depressed patients. Finally, we propose that the immune system uses the interoceptive pathway projecting to the insular cortex, a brain region where cytokine-induced changes in appetite could be partly mediated, and that this pathway is activated in depression.

  • Internet-delivered cognitive behavioral therapy for adolescents with insomnia : Feasibility and preliminary efficacy
  • 2024
  • Ingår i: Clinical Child Psychology and Psychiatry. - : Sage Publications. - 1359-1045 .- 1461-7021. ; 29:3, s. 1159-1173

    • Background Insomnia is common in adolescents. This study evaluated feasibility and preliminary efficacy of a six-week internet-delivered cognitive-behavioral therapy for insomnia (ICBT-I) in adolescents.Methods In this uncontrolled pilot study, participants (n = 27, 78% female) completed assessments pre- and post intervention. Data on recruitment, adherence to treatment, treatment activity, satisfaction and credibility was collected to assess feasibility. Self-reported insomnia symptoms, sleep parameters as well as depression, anxiety and daytime function were also assessed.Results Participants showed good adherence to treatment and found the intervention overall credible and satisfactory. From pre- to post-assessment, statistically significant improvements were found for insomnia symptoms (p < .001; d = 1.02), sleep onset latency (p < .001; d = .39), wake after sleep onset (p = .001; d = .34), sleep efficiency (p < .001; d = .5) and depression (p = .01, d = .37). Changes in scores of total sleep time, generalized anxiety, daytime sleepiness and functional disability were not significant.Conclusions The present study indicates that ICBT-I is well accepted by adolescents, that insomnia symptoms and sleep parameters can improve following the intervention, and that co-morbid symptoms of depression can be reduced. Due to the limited sample size and the uncontrolled design, the suggested results need to be replicated in well-powered controlled clinical trials.
