The opioid epidemic: Mobilizing an academic health center to improve outcomes

Exploring novel non-opioid pathways and therapeutics for pain modulation

The opioid crisis has highlighted the urgent need for alternative pain management strategies. This review explores novel non-opioid targets and pathways involved in pain modulation, highlighting advancements in understanding and therapeutic potential. Pain, a multifaceted phenomenon with nociceptive, neuropathic, and inflammatory components, involves intricate molecular signaling cascades. Key pathways reviewed include voltage-gated sodium channels (Nav1.7, Nav1.8, Nav1.9), inflammasome complexes (NLRP3), the kynurenine pathway, prostaglandins, and bradykinin-mediated signaling. Emerging therapeutics such as selective Nav channel blockers, NLRP3 inhibitors, kynurenine pathway modulators, EP receptor antagonists, and bradykinin receptor antagonists offer promising alternatives to opioids. Despite challenges in clinical translation, these developments signal a paradigm shift in pain management, with precision-focused therapies poised to address unmet needs. This review emphasizes the importance of integrating molecular insights into the development of safer, more effective analgesics, setting the stage for transformative advancements in non-opioid pain relief.

Evaluation of the New England Office Based Addiction Treatment ECHO: A Tool for Strengthening the Addiction Workforce

INTRODUCTION

Reducing substance-related morbidity requires an educated and well-supported workforce. The New England Office Based Addiction Treatment Extension for Community Healthcare Outcomes (NE OBAT ECHO) began in 2019 to support community-based addiction care teams through virtual mentoring and case-based learning. We sought to characterize the program's impact on the knowledge and attitudes of NE OBAT ECHO participants.

METHODS

We conducted an 18-month prospective evaluation of the NE OBAT ECHO. Participants registered for 1 of 2 successive ECHO clinics. Each 5-month clinic included ten 1.5-hour sessions involving brief didactic lectures and de-identified patient case presentations. Participants completed surveys at Month-0, -6, -12, and -18 to assess attitudes about working with patients who use drugs and evidence based practices (EBPs), stigma toward people who use drugs, and addiction treatment knowledge. We compared outcomes using 2 approaches: (i) between-groups, which involved comparing the first intervention group to the delayed intervention (comparison) group, and (ii) within-groups, which involved comparing outcomes at different time points for all participants. In the within-group approach, each participant acted as their own control.

RESULTS

Seventy-six health professionals participated in the NE OBAT ECHO, representing various roles in addiction care teams. Approximately half (47% [36/76]) practiced primary care, internal, or family medicine. The first intervention group reported improved job satisfaction and openness toward EBPs compared to the delayed intervention group. Within-group analyses revealed that ECHO participation was associated with increased positive perceptions of role adequacy, support, legitimacy, and satisfaction 6 months following program completion. No changes were identified in willingness to adopt EBPs or treatment knowledge. Stigma toward people who use drugs was persistent in both groups across time points.

CONCLUSIONS

NE OBAT ECHO may have improved participants' confidence and satisfaction providing addiction care. ECHO is likely an effective educational tool for expanding the capacity of the addiction workforce.

Investigation and analysis of four countries' recalls of osteosynthesis implants and joint replacement implants from 2011 to 2021

Background

Medical devices are used in almost all orthopedic surgical subspecialties, and the frequency of adverse events is increasing, which should not be ignored. To provide suggestions on how to avoid implant recalls from the perspective of manufacturers, medical institutions and supervisions, as well as how to respond promptly to adverse events.

Methods

The research extracted recalls of osteosynthesis implants and joint replacement implants from January 1, 2011, to June 30, 2021, in the CNMPA, FDA, HC and ATGA websites and collected the information on device name, recall time, recall class, recall manufacturer, device classification and affected areas. Moreover, the McKinsey 7S model and fishbone diagram were used to analyze recall reasons.

Results

A total of 315 cases of osteosynthesis implants and 286 cases of joint replacement implants were reported in China, the USA, Canada and Australia. The recalls number from 2016 to 2021 was more than that from 2011 to 2015 for osteosynthesis implant (p = 0.012) and joint replacement implant (p = 0.002), and both mainly focused on class II (76.19% and 78.32%). There were statistical differences in the four countries for both implants (p = 0.000), especially osteosynthesis implant between China and the USA (p = 0.000), China and Canada (p = 0.001), the USA and Australia (p = 0.002), and joint replacement implant between China and Australia (p = 0.000).

Conclusions

To avoid the recalls of such implants, manufacturers should strictly select implant materials and components, develop detailed labels and instructions, severely control the packaging process and establish the integrity of medical device data. Medical institutions should standardize procurement procedures, use qualified equipment and train medical workers. It also requires supervisions to conduct premarket safety assessments. In addition, regulators should strengthen supervision and establish reporting systems to deal with the occurrence of adverse events promptly.
