Abstract

Background Sleep disturbance is associated with activation of systemic and cellular inflammation, as well as proinflammatory transcriptional profiles in circulating leukocytes. Whether treatments that target insomnia-related complaints might reverse these markers of inflammation in older adults with insomnia is not known.Methods In this randomized trial, 123 older adults with insomnia were randomly assigned to cognitive-behavioral therapy for insomnia (CBT-I), tai chi chih (TCC), or sleep seminar education active control condition for 2-hour sessions weekly over 4 months with follow-up at 7 and 16 months. We measured C-reactive protein (CRP) at baseline and months 4 and 16; toll-like receptor-4 activated monocyte production of proinflammatory cytokines at baseline and months 2, 4, 7, and 16; and genome-wide transcriptional profiling at baseline and month 4.Results As compared with sleep seminar education active control condition, CBT-I reduced levels of CRP (months 4 and 16, ps < .05), monocyte production of proinflammatory cytokines (month 2 only, p < .05), and proinflammatory gene expression (month 4, p < .01). TCC marginally reduced CRP (month 4, p = .06) and significantly reduced monocyte production of proinflammatory cytokines (months 2, 4, 7, and 16; all ps < .05) and proinflammatory gene expression (month 4, p < .001). In CBT-I and TCC, TELiS promoter-based bioinformatics analyses indicated reduced activity of nuclear factor-κB and AP-1.Conclusions Among older adults with insomnia, CBT-I reduced systemic inflammation, TCC reduced cellular inflammatory responses, and both treatments reduced expression of genes encoding proinflammatory mediators. The findings provide an evidence-based molecular framework to understand the potential salutary effects of insomnia treatment on inflammation, with implications for inflammatory disease risk.

  • The APOE ε4 allele is associated with late-life depression in humans.

    “Population-based studies reveal that apolipoprotein E (APOE) ε4 gene allele is closely associated with late-life depression (LLD).”

    From APOE4 genotype exacerbates the depression-like behavior of mice during aging through ATP decline (2021) · cites this paper as [2]

    The Introduction (page unavailable) links poor sleep and inflammatory markers to depression, but does not discuss APOE ε4. Searches of our copy for APOE ε4, apolipoprotein E, and a population-based genetic association found no passage addressing the claimed link with late-life depression. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • There are approximately as many studies of APOE ε4 and depression that report positive results as those that find null results.

    “there are approximately as many studies of APOE ε4 and depression that report positive results as those that find null results [2].”

    From APOE4 genotype exacerbates the depression-like behavior of mice during aging through ATP decline (2021) · cites this paper as [2]

    The Methods and Results passages concern inflammatory markers in a late-life insomnia trial, while the References mention depression without addressing APOE ε4. Searches for APOE ε4, apolipoprotein E, and positive versus null depression findings found no passage in our copy comparing those studies. (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • In one of the largest CBT-I studies with over 100 older adults suffering from primary insomnia, CBT-I resulted in lower levels of CRP throughout the 16-mo follow-up period compared with adults receiving sleep education, and this decrease was associated with remission of insomnia.

    “In one of the largest CBT-I studies with over 100 older adults suffering from primary insomnia, CBT-I resulted in lower levels of CRP throughout the 16-mo follow-up period compared with adults receiving sleep education, and this decrease was associated with remission of insomnia (258).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
