PainRelief.com: What is the background for this study?

Response:    Opioid medications tap into the body’s natural system for mitigating pain by activating pain-suppressing opioid receptors on neurons. Although meant to help, sometimes these medications do harm.  Opioid medications offer people relief from debilitating pain, but these drugs come with dangers: the risk for addiction, miserable withdrawal symptoms and the potential for fatal overdose.  New mechanistic insights into the function and regulation of the opioid receptors present the opportunity to design new, safer opioid painkillers. The team’s previous research utilized a strategy to design functionally selective “bitopic” opioids by targeting the sodium binding allosteric site in the opioid receptor.

PainRelief.com: What is the background for this study?

Response: Overprescribing is linked to opioid misuse and overdose, with household supplies of opioids associated with an increased risk of overdose as many people do not dispose of unused medications safely. In Canada, more than 7570 people died of opioid overdoses in 2021, and more than 68 000 people died in the United States in 2020 from these same drugs.

NEJM: Despite Removal of DEA Waiver Requirement, Buprenorphine Still Widely Underprescribed for Opioid Addiction

PainRelief.com: What is the background for this study?
Response: Buprenorphine is one of 3 FDA-approved medications to treat opioid addiction. It is the only one of the 3 that can be prescribed during office visits. Although buprenorphine is highly effective in treating opioid addiction, it is widely underused. Addressing this underuse is a key step towards slowing the epidemic of U.S. opioid overdose deaths.

In 2000, the federal government allowed clinicians to prescribe buprenorphine if they obtained a waiver from the Drug Enforcement Administration. Clinicians have cited the waiver requirement as a key barrier to buprenorphine prescribing. In part because of this, the government eliminated this requirement on January 12, 2023.

Neuropathy: Repeated High Concentration Capsaicin Patches Provided Back Pain Relief and Reduced Need for Opioids

PainRelief.com Interview with:
Kai-Uwe Kern MD, PhD
Institute of Pain Medicine/Pain Practice
Wiesbaden, Germany

PainRelief.com: What is the background for this study?

Response: In recent studies a progressive response to high-concentration capsaicin patch (HCCP) with repeated treatment was observed, meaning that patients with insufficient pain relief after the first application of HCCP, still may respond to a second, third, or even fourth application. Based on these latest findings, and also on my personal clinical experience, we aimed to systematically analyse the pool of patients in my Pain Practice with at least two HCCP treatments.

NCCIH Study Finds Marked Increase in Complementary Health Approaches Among US Adults, Including for Pain Management

Lead Epidemiologist

NCCIH

PainRelief.com: What is the background for this study?

Response: Millions of US adults use complementary health approaches (CHAs) each year. CHAs are health approaches typically not part of conventional medical care or with origins outside of Western medicine that are used together with conventional medical practice.

Some of the most well-known complementary health approaches include meditation, acupuncture, and yoga. While the safety and efficacy of many of these approaches previously lacked rigorous clinical trials, the last two decades saw an increase in evidence supporting the use of select approaches to manage health and pain.

PainRelief.com: What is the background for this study?


Response: Recent research from Dr Lauren Jantzie at John Hopkins found that in mice prenatal opioid exposure altered the immune system.
Our research aimed to see if the same was true in children who had been exposed to opioids in utero.

PainRelief.com: What is the background for this study?

Response: In this pilot study, we examined longer-term changes after the Mindfulness-Oriented Recovery Enhancement (MORE) intervention and immediate effects of a brief MORE guided meditation session in women with opioid use disorder (OUD) who were on medications for OUD (MOUD). Participants completed the first assessment, then the 8-week MORE intervention (once weekly for two hours) during residential treatment, and then the second assessment.


The assessments were identical and conducted at Rutgers University Brain Imaging Center in Newark.

First, participants completed an emotion regulation questionnaire, and then they entered the magnetic resonance imaging (MRI) environment for scanning. Participants listened to a 10-minute guided MORE meditation in the scanner while viewing a picture of an outdoor garden, and brain images were recorded to measure functional connectivity (i.e., brain communication) during the meditation. We examined the immediate effects of a 10-minute guided MORE meditation on mood and craving. We further examined the effects of 8-week MORE intervention on changes in emotional regulation difficulty and brain communication.

Cancer Doctors Prescribing Fewer Opioids Since Opioid Crisis

PainRelief.com Interview with:
Joshua Kra, MD
Assistant Professor of Medicine, Rutgers NJMS
Division of Hematology/Oncology
Rutgers Cancer Institute of New Jersey at University Hospital

PainRelief.com: What is the background for this study?

Response: We aimed to characterize pain management practices by medical oncologists to assess whether CDC guidelines from 2017 for nononcologic settings changed prescribing patterns for oncologists.

PainRelief.com: What are the main findings?

Response: There was a significant decrease in opioid prescriptions from medical oncologists starting in 2017, which coincided with the recognition of the opioid crisis as a national public health emergency and the publication of CDC guidelines for opiate prescribing in non-cancer settings. This would suggest these factors contributed to how oncologists changed their management of opioid prescriptions for cancer patients.

Opioid Prescriptions by Surgeons for Post-Op Pain Relief Decline, but Progress Has Slowed

PainRelief.com: What is the background for this study?

Response: Surgery is one of the most common reasons for opioid prescribing. Ensuring the appropriateness of opioid prescribing by surgeons is important, as prescriptions that exceed patient need result in leftover pills that can be a source for misuse or diversion. Although there have been numerous recent policy and clinical efforts to improve opioid prescribing by surgeons, recent national data on this prescribing are unavailable.

In this study, we analyzed a comprehensive prescription dispensing database that captures 92% of prescriptions from U.S. pharmacies. From 2016 to 2022, we found that the rate of surgical opioid prescriptions at the population level declined by 36%, while the average amount of opioids in these prescriptions declined by 46%. As a result of these two changes, the total amount of opioids dispensed to surgical patients declined by 66%.

However, there were two caveats:

First, the decline in surgical opioid prescribing was most rapid before 2020 and has slowed since then.

Second, the average surgical opioid prescription in December 2022 still contained the equivalent of about 44 pills containing 5 milligrams of hydrocodone, far higher than most patients need after surgery.

Rutgers Study Finds Modest Decrease in Non-Prescription Opioid Use with Cannabis Legalization, But Concentrated in People Addicted to Cannabis

PainRelief.com: What is the background for this study?

Response: Early studies suggesting that cannabis legalization is associated with lower rates of opioid-related harms received considerable media attention. At the time, overdose deaths were driven by prescription opioids, and medical cannabis was often framed as a policy approach to address the opioid epidemic. However, as research in this area grew, the relationship between medical cannabis legalization and opioid-related harms became less clear. Many studies of cannabis legalization were unable to examine opioid use by individual people, and individual-level studies outside the legal context showed links between cannabis use and higher risk of opioid-related harms. Thus, our goal was to build evidence of the relationship between medical cannabis legalization and individual-level opioid use.
