| Abstract |
Lymphocyte apoptosis in critical illness is associated with immunosuppression. We explored for the first time the associations between pain ratings and expression of the apoptotic receptor Fas on B and T cells in critically ill patients and the potential mediating effects of adrenocorticotropic hormone (ACTH), cortisol, and substance P (SP). This is an exploratory correlational study with repeated measurements (14 days followup) and cross-sectional comparisons. This study was conducted in a state hospital in the metropolitan area of Athens, Greece. The participants were 36 consecutive critically ill patients and 36 matched controls. Pain measured by the self-reported numeric rating scale [NRS], the behavioral pain scale, and the pain assessment scale was the primary outcome measure. Flow cytometry (Fas), electrochemiluminescence (ACTH and cortisol) and enzyme-linked immunosorbent assay (SP) were used. Mixed linear models for repeated measurements and bivariable associations at discrete time points were employed. Significant pain at rest was noted. Pain ratings associated with Fas expression on cytotoxic T cells (P=0.041) and B cells (P=0.005), even after adjustment for a number of clinical treatment factors (P=0.006 and P=0.052, respectively). On the day that more patients were able to communicate, Fas on B cells (r=0.897, P=0.029) and cytotoxic T cells (r=0.832; P=0.037) associated with NRS ratings. Associations between pain ratings and ACTH serum levels were noted (P<0.05). When stress neuropeptide levels were added to the model, the statistical significance of the associations between pain ratings and Fas expression was attenuated (P=0.052-0.063), suggesting that stress neuropeptides may partially mediate the association. Preliminary evidence for the association between pain and lymphocyte apoptotic susceptibility is provided. The role of pain management in maintaining immunocompetence in critical illness is worth exploring. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 February 2017.
All research outputs
#15,879,822
of 25,584,565 outputs
Outputs from Journal of Pain Research
#1,123
of 1,969 outputs
Outputs of similar age
#236,934
of 422,901 outputs
Outputs of similar age from Journal of Pain Research
#31
of 50 outputs
Altmetric has tracked 25,584,565 research outputs across all sources so far. This one is in the 36th percentile – i.e., 36% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,969 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 14.3. This one is in the 40th percentile – i.e., 40% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 422,901 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 50 others from the same source and published within six weeks on either side of this one. This one is in the 34th percentile – i.e., 34% of its contemporaries scored the same or lower than it.
