Brief Summary:
This pilot research study is being performed to learn more about pain and look at how pain changes brain chemistry and function. The research team would like to learn new information to better control chronic pain after surgery. This information collected in this research will be used to plan possible future visits. Participants in this study are being asked to participate because they are scheduled for an upcoming surgery. The research team would like to observe them before and after their surgery.

Condition or disease
Chronic Post-surgical Pain

Detailed Description:
This study is a pilot feasibility study in 30 healthy, preoperative children and young adults undergoing major surgery with high risk for chronic post-surgical pain (CPSP) to characterize the brain metabolite status of the Anterior cingulate cortices (ACC) and insula in pre-surgical adolescents and to understand the relationship between metabolite levels and CPSP. The investigators will also examine whether neurochemical tone in these regions is related to resting state functional connectivity with other brain regions. Correlations between differentially methylated CpG sites in genes enriching gamma aminobutyric acid (GABA) and Dopamine-DARPP-32 pathways and Glu/GABA levels in insula/ACC will be analyzed.

Study Type : Observational
Estimated Enrollment : 30 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Pilot Study Evaluating Neuro-Imaging Correlates of Epigenetic Finding in Prediction of Chronic Postsurgical Pain
Actual Study Start Date : December 14, 2020
Estimated Primary Completion Date : December 1, 2022
Estimated Study Completion Date : December 1, 2022



Primary Outcome Measures :
  1. Chronic post-surgical pain; Unabbreviated scale title "Chronic post-surgical pain scores" [ Time Frame: 2-6 months after surgery ]
    Pain scores over prior 2 weeks reported 2-6 months after surgery; minimum value = 0, maximum value = 10; higher score means more severe pain


Secondary Outcome Measures :
  1. Evoked pressure pain measures; Unabbreviated scale title "Evoked pressure pain measures" [ Time Frame: 1-2 weeks after surgery ]
    Average of 3 measurements taken using a hand-held algometer; minimum value = 0, maximum value = None; higher measurement means better pain tolerance

  2. Resting state connectivity [ Time Frame: 1 - 8 weeks before surgery ]
    Pressure cuff measurements while undergoing MRI scan

  3. Correlation of DNAm of specified gene regions with outcomes [ Time Frame: 1-8 weeks before surgery or day of surgery ]
    Differential DNAm measured by array/sequencing


Biospecimen Retention:   Samples With DNA

DNA will be isolated from blood samples and be used for pyrosequencing studies to obtain DNA methylation information for a specified set of genes or use of the Methylation EPIC array.

DNA samples gathered will be held for future analysis.
