#WeAreAllInThis Together COVID-19 Journal Club

The COVID-19 Global Pandemic has posed significant challenges to the pain community. To reinforce the message that the we—those who do human pain research—are part of a community, I put together the COVID-19 Journal Club (or as some like to call it, the #PainStars Forum). It's an opportunity to connect, to remain intellectually stimulated, to learn, and to keep up with the literature. 

We meet over Zoom every month, on a Thursday. The specifics, papers, and link to the Zoom will be posted here. We look forward to seeing you all. And #WeAreAllInThisTogether.

Title: Using fMRI hyperscanning to investigate the patient-clinician relationship in chronic pain: The role of therapeutic alliance, behavioral mirroring, and brain-to-brain concordance in therapeutic pain relief


Presented by: Dr. Dan-Mikael Ellingsen, Postdoctoral research fellow (Napadow Lab), Harvard Medical School and Martinos Center for Biomedical imaging, Boston, USA.

 

Abstract: The patient-clinician interaction can powerfully shape treatment outcomes such as pain, but is often considered an intangible “art-of-medicine”, and has largely eluded scientific inquiry. Although brain correlates of social processes such as em- pathy and theory-of-mind have been studied using single-subject designs, the spe- cific behavioral and neural mechanisms underpinning the patient-clinician interac- tion are unknown. Using a two-person interactive design, we simultaneously rec- orded functional MRI (i.e. hyperscanning) in patient-clinician dyads, who interacted via live video while clinicians treated evoked pain in chronic pain patients. Our re- sults show that patient analgesia is mediated by patient-clinician nonverbal behav- ioral mirroring and brain-to-brain concordance in circuitry implicated in theory-of- mind and social mirroring. Dyad-based analyses showed extensive dynamic cou- pling of these brain nodes with the partners’ brain activity, yet only in dyads where clinical rapport had been established prior to the interaction. These findings point to a putatively key brain-behavioral mechanism for therapeutic alliance and psycho- social analgesia.

Title: The Distributed Nociceptive System: A Framework for Understanding Pain


Presented by: Dr. Robert C. Coghill, Director, Center for Understanding Pediatric Pain (CUPP), Professor of Pediatrics Behavioral Medicine and Clinical Psychology, Cincinnati Children’s Hospital Medical Center

 

Abstract: Chronic pain remains challenging to both diagnose and treat. These challenges, in part, arise from limited systems-level understanding of the basic mechanisms that process nociceptive information and ultimately instantiate a subjectively available experience of pain. Here, I provide a framework, the distributed nociceptive system, for understanding nociceptive mechanisms at a systems level by integrat- ing the concepts of neural population coding with distributed processing. Within this framework, wide-spread engagement of populations of neurons produces representations of nociceptive information that are highly resilient to disruption. The distributed nociceptive system provides a foundation for understanding complex spatial aspects of chronic pain and provides an impetus for nonpharmacological cognitive and physical therapies that can effectively target the highly distributed system that gives rise to an experience of pain.

DATABLITZ RESULTS

I would like to start by thanking all the trainees for presenting their data at our DataBlitz. The presentations were of very high quality. It was a really successful event, and it achieved — at least for me — to build a sense of community. 

We had 29 presentations representing 25 labs.


I would also like to thank the judges, Lauren Atlas, Rachael Bosma, Iacopo Cioffi, Yenisel Cruz-Almeida, Patrick Finan, and Laura Stone, for their time and thoughtful comments. None of this would have been possible without them. 

I would also like to thank the sponsors: IASP, the Canadian Pain Society and QST-Lab.

Title: “But for pain words are lacking”: using language features to predict placebo analgesia in chronic pain. (New Data; Unpublished work)

Presented by: Dr. Paulo Branco, Postdoctoral Fellow at Apkarian Pain and Passions lab, Northwestern University, Chicago, USA.

Abstract: “But for pain words are lacking”, writes Virginia Woolf in her Magnum Opus, The Waves. And indeed, even though language is rich in meaning and is seen as “a window to the soul”, the discourse of patients with chronic illness and pain – like Woolf herself – have long been neglected. Natural language processing (NLP) is a relatively popular technique that extracts languages features out of discourse reflecting the person’s personality, behavior and mood. In this study, we hypothesize that chronic back pain patients who respond to placebo will show specific language patterns that can be picked up, quantified, and used to classify and infer the extent of analgesia after placebo pill ingestion. We were able to classify placebo responders with high accuracy (79% cross-validated). Further, with just three language features (semantic proximity to stigma, identity, and text tags associated with achievement) we were able to explain 50% of the variance in the reported pain after treatment. Predictive language features were also associated with personality traits and are not explained by treatment effects alone. Together, these show high promise to the use of quantitative language features to study placebo analgesia and have important implications for both the design of clinical trials and, conceivably, for identifying subjects that can benefit from placebo as a treatment option for chronic pain.

PANEL DISCUSSION: WHAT HAS ​IMAGING ADDED TO OUR UNDERSTANDING OF PAIN

A recent editorial in the journal Brain (https://academic.oup.com/brain/article-abstract/143/4/1045/5823483?redirectedFrom=fulltextcriticized brain imaging (in particular fMRI) and stated that it has offered little to our understanding of brain-based disease, and has little (if any) clinical utility. 

I thought it would be a good exercise to have a discussion about fMRI/sMRI papers that have had a meaningful impact on our mechanistic understanding of pain, or that have had meaningful clinical impact. This is a useful exercise for us to pull back and to think about the work we do.

SYMPOSIUM: ​PAIN AND EMOTION—BRAIN, BODY, AND BEYOND

Pain and emotion are tightly linked, but are traditionally studied and treated separately. This symposium highlights conceptual, psychological, and neural intersections between these two constructs, emphasizing opportunity for collaborations across the pain and affective science research and clinical communities. Our diverse panel of speakers combine innovative experimental methodologies and conceptual models, from basic animal and human research, to clinical research in chronic pain patients
