Relationships between changes in pain severity and other patient-reported outcomes: an analysis in patients with posttraumatic peripheral neuropathic pain.

ABSTRACT: The objective of this study is to use the pain numeric rating scale (NRS) to evaluate associations between change in pain severity and changes in sleep, function, and mood assessed via patient-reported outcomes (PROs) in patients with posttraumatic pain.This is a secondary analysis of a clinical trial evaluating pregabalin in patients with posttraumatic peripheral neuropathic pain (N = 254). Regression models were used to determine associations between changes in pain (0-10 NRS) as the predictor and scores on the following PRO measures as the outcome: Pain Interference Index; Hospital Anxiety and Depression Scale anxiety and depression subscales; Medical Outcomes Study-Sleep Scale 9-item Sleep Problems Index and Sleep Disturbance subscale; and Daily Sleep Interference Scale (0-10 NRS).Change in pain severity showed clear, direct relationships with changes in function, anxiety, depression, and sleep PROs, all of which were statistically significant (P <.001). Results from subgroup analyses (?30% or ?50% pain responders, pregabalin or placebo treatment, age ? 51 years or > 51 years) tended to be consistent with results from the overall sample.Overall, a direct relationship exists between pain and various aspects of patient's well-being and functioning, which can provide a quantitative assessment of how improvements in pain may be expected to relate to other patient outcomes.

Project description:Peripheral nerve injury alters the expression of hundreds of proteins in dorsal root ganglia (DRG). Targeting some of these proteins has led to successful treatments for acute pain, but not for sustained postoperative neuropathic pain. The latter may require targeting multiple proteins. Since a single microRNA (miR) can affect the expression of multiple proteins, here, we describe an approach to identify chronic neuropathic pain-relevant miRs. We used two variants of the spared nerve injury (SNI): Sural-SNI and Tibial-SNI and found distinct pain phenotypes between the two. Both models induced strong mechanical allodynia, but only Sural-SNI rats maintained strong mechanical and cold allodynia, as previously reported. In contrast, we found that Tibial-SNI rats recovered from mechanical allodynia and never developed cold allodynia. Since both models involve nerve injury, we increased the probability of identifying differentially regulated miRs that correlated with the quality and magnitude of neuropathic pain and decreased the probability of detecting miRs that are solely involved in neuronal regeneration. We found seven such miRs in L3-L5 DRG. The expression of these miRs increased in Tibial-SNI. These miRs displayed a lower level of expression in Sural-SNI, with four having levels lower than those in sham animals. Bioinformatics analysis of how these miRs could affect the expression of some ion channels supports the view that, following a peripheral nerve injury, the increase of the 7 miRs may contribute to the recovery from neuropathic pain while the decrease of four of them may contribute to the development of chronic neuropathic pain. The approach used resulted in the identification of a small number of potentially neuropathic pain relevant miRs. Additional studies are required to investigate whether manipulating the expression of the identified miRs in primary sensory neurons can prevent or ameliorate chronic neuropathic pain following peripheral nerve injuries. To identify the miRs that were differentially dysregulated between Tibial-SNI and Sural-SNI, we first performed 12 microarrays in a limited number of samples (in four individual DRGs per group: Sham, Tibial-SNI and Sural-SNI; two L3-DRG and two L4-DRG). Then, miRs identified as having differential expression were corroborated with real time qRT-PCR in RNA isolated from individual DRGs (L3, L4 and L5) derived from 4 rats per group (not presented here, but in the manuscript).

Project description:BackgroundGlobally, with the COVID-19 pandemic, dental services were limited to emergency/ urgent conditions and were provided only after tele-triage referral for face-to-face management. However, no previous research explored whether the pain severity (PS) drives the tele-triage decisions. The current study examined the association between PS and tele-triage decision of whether to manage the condition remotely or refer the caller for face-to-face management.MethodsThis retrospective cross-sectional study analyzed the PS reported by hotline callers, using numerical rating scale (NRS-11), during the first wave of COVID-19 lockdown (23 March-31 August 2020) and its association with tele-triage decision controlling for age, sex, history of chronic illness, and dental discipline needed. Binomial logistic regression assessed the association between the PS (exposure) and tele-triage decision (outcome). ANOVA compared PS across tele-triage categories, dental history and tentative diagnosis.ResultsPS was significantly associated with tele-triage decisions (p < 0.05). An increase in pain score by 1 unit was associated with 1.4 times increased odds of face-face referral (95% CI: 1.26-1.54). Pediatric/ adolescent patients (9-18 years) (odds ratio (OR) = 2.07; 95% CI: 1.07-4.02), history of chronic illness (OR = 2.12; 95% CI:1.28-3.51), need for surgical specialty (OR = 1.93; 95% CI: 1.22-3.04) and orthodontic specialty (OR = 7.02; 95% CI: 3.54-13.87) were independently associated with tele-triage decision. PS was highest for the emergency triage category (8.00 ± 2.83, P < 0.0001), dental history of tooth with cavity or filling (6.65 ± 2.024, P < 0.0001), and the tentative tele-diagnosis of cellulitis (7.75 ± 2.872, P < 0.0001).ConclusionsDuring COVID-19 pandemic, tele-triage decisions were significantly influenced by patient-reported PS, adjusting for a range of variables. Despite this, referral for face-to-face management was individualized and driven by the tripartite considerations of the reported pain, clinical judgement, and the high transmission characteristics of COVID-19.
