mHealth Coping Skills Training for Symptom Management (mCOPE) for colorectal Cancer patients in early to mid-adulthood: Study protocol for a randomized controlled trial

Background

Colorectal cancer (CRC) patients in early to mid-adulthood (≤50 years) are challenged by high symptom burden (i.e., pain, fatigue, distress) and age-related stressors (e.g., managing family, work). Cognitive behavioral theory (CBT)-based coping skills training interventions reduce symptoms and improve quality of life in cancer patients. However, traditional CBT-based interventions are not accessible to these patients (e.g., in-person sessions, during work day), nor designed to address symptoms within the context of this stage of life. We developed a mobile health (mHealth) coping skills training program for pain, fatigue and distress (mCOPE) for CRC patients in early to mid-adulthood. We utilize a randomized controlled trial to test the extent to which mCOPE reduces pain, fatigue and distress (multiple primary outcomes) and improves quality of life and symptom self-efficacy (secondary outcomes).

Methods/Design

Patients (N = 160) ≤50 years with CRC endorsing pain, fatigue and/or distress are randomized 1:1 to mCOPE or standard care. mCOPE is a five-session CBT-based coping skills training program (e.g., relaxation, activity pacing, cognitive restructuring) that was adapted for CRC patients in early to mid-adulthood. mCOPE utilizes mHealth technology (e.g., videoconference, mobile app) to deliver coping skills training, capture symptom and skills use data, and provide personalized support and feedback. Self-report assessments are completed at baseline, post-treatment (5-8 weeks post-baseline; primary endpoint), and 3- and 6-months later.

Conclusions

mCOPE is innovative and potentially impactful for CRC patients in early to mid-adulthood. Hypothesis confirmation would demonstrate initial efficacy of a mHealth cognitive behavioral intervention to reduce symptom burden in younger CRC patients.

Microbiota-Pain Association; Recent Discoveries and Research Progress

The relationship between gut microbiota and pain, such as visceral pain, headaches (migraine), itching, prosthetic joint infection (PJI), chronic abdominal pain (CAP), joint pain, etc., has received increasing attention. Several parts of the evidence suggest that microbiota is one of the most important pain modulators and they can regulate pain in the central and peripheral nervous systems. Any alteration in microbiota by diet or antibiotics mediation may characterize a novel therapeutic strategy for pain management. The present study includes the most up-to-date and influential scientific findings on the association of microbiota with pain, despite the fact that the underlying mechanism is not identified in most cases. According to recent research, identifying the molecular mechanisms of the microbiota-pain pathway can have a unique perspective in treating many diseases, even though there is a long way to reach the ideal point. This study will stress the influence of microbiota on the common diseases that can stimulate the pain with a focus on underlying mechanisms.

Modulation of Glia-Mediated Processes by Spinal Cord Stimulation in Animal Models of Neuropathic Pain

Glial cells play an essential role in maintaining the proper functioning of the nervous system. They are more abundant than neurons in most neural tissues and provide metabolic and catabolic regulation, maintaining the homeostatic balance at the synapse. Chronic pain is generated and sustained by the disruption of glia-mediated processes in the central nervous system resulting in unbalanced neuron–glial interactions. Animal models of neuropathic pain have been used to demonstrate that changes in immune and neuroinflammatory processes occur in the course of pain chronification. Spinal cord stimulation (SCS) is an electrical neuromodulation therapy proven safe and effective for treating intractable chronic pain. Traditional SCS therapies were developed based on the gate control theory of pain and rely on stimulating large Aβ neurons to induce paresthesia in the painful dermatome intended to mask nociceptive input carried out by small sensory neurons. A paradigm shift was introduced with SCS treatments that do not require paresthesia to provide effective pain relief. Efforts to understand the mechanism of action of SCS have considered the role of glial cells and the effect of electrical parameters on neuron–glial interactions. Recent work has provided evidence that SCS affects expression levels of glia-related genes and proteins. This inspired the development of a differential target multiplexed programming (DTMP) approach using electrical signals that can rebalance neuroglial interactions by targeting neurons and glial cells differentially. Our group pioneered the utilization of transcriptomic and proteomic analyses to identify the mechanism of action by which SCS works, emphasizing the DTMP approach. This is an account of evidence demonstrating the effect of SCS on glia-mediated processes using neuropathic pain models, emphasizing studies that rely on the evaluation of large sets of genes and proteins. We show that SCS using a DTMP approach strongly affects the expression of neuron and glia-specific transcriptomes while modulating them toward expression levels of healthy animals. The ability of DTMP to modulate key genes and proteins involved in glia-mediated processes affected by pain toward levels found in uninjured animals demonstrates a shift in the neuron–glial environment promoting analgesia.
