Given that metabolic factors and chronic neuropathic pain are related, we evaluated potential secondary effects of 10kHz SCS on hemoglobin A1c (HbA1c) and weight in SENZA-PDN participants with type 2 diabetes (T2D).Patients and Methods: This analysis included 144 participants with T2D and lower limb pain due to PDN who received 10kHz SCS during the SENZA-PDN study. Changes in HbA1c, weight, pain intensity, and sleep were evaluated over 24 months, with participants stratified according to preimplantation HbA1c (> 7% and > 8%) and body mass index (BMI; ≥ 30 and ≥ 35 kg/m2).Results: At 24 months, participants with preimplantation HbA1c > 7% and > 8% achieved clinically meaningful and statistically significant mean reductions in HbA1c of 0.5% (P = 0.031) and 1.1%

This study aims to understand the possible contributing factors starting with Pain Medicine fellowship training.Materials and Methods: An internet-based, anonymous pilot survey was distributed to pain medicine fellows enrolled in an Accreditation Council for Graduate Medical Education (ACGME) accredited pain medicine training program during the 2021– 2022 academic year. Fellowship programs were identified using published online ACGME accreditation data. The survey was distributed via email to fellowship program directors and coordinators and was made available through pain medicine societies.Results: Seventy-one of four hundred and twenty-three pain medicine fellows (17% response rate) completed the survey. Nine percent of respondents evidence-informed opinion coincided with the most recent Polyanalgesic Consensus Conference (PACC) guidelines recommendations for IDDS treatment indication

Waves of infection led to a disjointed ability to provide care and conduct clinical research.

Though it originated as a medium for friendship, social media has evolved into an ideal venue for professional networking, scientific exchange, and brand building. As such, it is a powerful tool with which interventional pain physicians should become familiar. However, given the permanence and visibility of online posts, it is prudent for interventional pain physicians to utilize social media in a manner that is consistent with the ethical

Markham #515, Little Rock, AR, 72205, USA, Email jhgoree@uams.eduObjective: Spinal cord stimulation is a proven, evidence-based therapy for persistent spinal pain syndrome. While some patients with this disease are managed by chronic pain physicians, many are managed in primary care offices. Despite mounting evidence, dissemination of this research outside of neuromodulation related fields and implementation of this treatment in common practice has not yet occurred. We hypothesize that family medicine residents in rural training programs will have little knowledge of neuromodulation despite it being an evidence-based and common treatment of post-laminectomy syndrome.Materials and Methods: Online surveys were sent to family medicine residents in six rural family medicine training programs at the University of Arkansas for Medical Sciences Regional Programs to characterize knowledge of neuromodulation as a treatment for post-laminectomy syndrome.Results: Forty-one percent of responding rural, Arkansas family medicine residents reported treating post-laminectomy syndrome during their training, yet only 10% have referred a patient for neuromodulation consultation. Residents rated their knowledge of neuromodulation/spinal cord stimulation at 19 on a scale of 0 (no knowledge) to 100 (extensive knowledge).Conclusion: Despite proof that neuromodulation is an evidence-based treatment for post-lamin
