PRICE is a multi-college Center of Excellence that serves as the professional home for UF scientists, clinicians and trainees dedicated to improved understanding and treatment of pain. PRICE is affiliated with and supported by the UF Clinical and Translational Science Institute (CTSI), and receives strong support from the UF Institute on Aging and the UFHealth Cancer Center. PRICE provides member

investigators with several resources and services in order to facilitate clinical and translational pain research at UF, including assistance with protocol development and assistance with recruitment of research participants. Also PRICE offers facilities and services to assist investigators with collection of pain assessment data in their research protocols, via the Pain Clinical Research Unit (see below). Investigators can conduct their own studies in the PainCRU, or they can request that the PainCRU staff collect the data for their protocol. In addition, PRICE endeavors to enhance the intellectual and professional work environment for the UF pain research community by coordinating training activities related to pain, including our T32 training grant in translational pain research, as well as journal clubs, seminar series, and a monthly Pain Interest Group. In 2013, PRICE occupied its physical home in the new Clinical and Translational Research Building (CTRB), a state-of-the-art research building that serves as the home for clinical and translational research at the University of Florida. The CTRB provides offices for the PRICE Director, multiple PRICE research coordinators and staff, as well as the Director of the Pain Clinical Research Unit (see below). Pain Clinical Research Unit (PainCRU): The PainCRU (Director, Dr. Joe Riley) is a component of PRICE, which provides a patient-oriented research venue designed to facilitate and foster clinical and translational pain research at UF. The PainCRU currently occupies more than 2,000 square feet of space, which includes two CTRB locations, including the Clinical Research Center and the Institute on Aging’s Aging Rehabilitation Research Center (ARRC), as well as an additional location on the second floor of the Dental Tower at the University of Florida Health Sciences Center. Altogether, the PainCRU includes six fully equipped psychophysical testing units, each approximately 150 square feet. The laboratory space also includes multiple clinical examination and interview rooms. Each of the six sensory testing units is equipped for assessing thermal pain and pressure pain (equipment list), and four of the laboratories are also equipped for assessing cold pressor pain. All units include equipment for measuring cardiovascular responses. The PainCRU facilities in the CTRB are contiguous with the greatly expanded UF Clinical Research Center (CRC), which has multiple general use examination rooms, laboratory and sample processing facilities, as well as several infusion and procedure rooms. The UF CRC offers nursing support for PainCRU studies that involve repeated blood draws and/or administration of medications.

A psychologically based approach known as pain reprocessing therapy or PRT reduced chronic back pain (CBP) more than placebo or usual care – and the relief persisted 5 years after the original therapy was received, according to a new follow-up study.

Some study participants reported full recovery from their back pain after PRT sessions, which are based in CBT techniques.

Can a placebo you know is a placebo help with pain when combined with mindfulness?

A new study involving researchers from across the nation including Roger Fillingim, is exploring whether pairing mindfulness-based stress reduction (MBSR) with an open-label placebo (OLP), a placebo taken without any deception, can better relieve chronic pain compared to either treatment alone.

This first step is all about seeing if the study approach works smoothly, so researchers can move on to a bigger trial. If successful, it could open up new, non-opioid ways to manage chronic pain!

A new study examined how well older adults remember their levels of pain, mood, and fatigue compared to real-time reports collected throughout the day.

Researchers at UF, including Yenisel Cruz-Almeida recorded 26 participants who used a smartphone-based ecological momentary assessment to record their pain, mood and fatigue three times a day for two weeks. On the 15th day, they recalled their average levels.

Findings showed that greater fluctuations in pain intensity led to less accurate recall, even when accounting for peak and end pain levels and number of painful areas. Interestingly, this effect did not apply to mood or fatigue, suggesting that memory distortions are particularly linked to pain variability.

Every fourth Wednesday of each month, we cover new and emerging studies and breakthroughs in pain research. Take part in an open forum conducted by peers and experts in the field!

This month, Dr. Muhammad Abbas will discuss the article, GDF15 enhances proliferation of aged chondrocytes by phosphorylating SMAD2" which explores how GDF15, a protein in the TGF-β signaling pathway, affects the growth of cartilage cells (chondrocytes) in aging, which is important for osteoarthritis development.

Researchers at UF including Carlos Cruz, Folly Patterson and Kyle Allen wanted to discover if having high blood pressure (hypertension) makes osteoarthritis (OA) worse and whether this effect differs between males and females. To do this, they studied rats with and without hypertension who also had surgically induced knee OA.

During the study, it was found that when hypertension and osteoarthritis occurred together, joint damage was more severe. Female rats developed bigger bone spurs, more changes in the blood vessels around the joint, and even started limping with shorter steps. Interestingly, males didn’t show the same level of problems.

This research shows how conditions like hypertension and arthritis can interact in surprising ways and why it’s important to look at s*x differences when studying joint health!

Your mindset might be doing more than just shaping your mood, it could also be affecting how your body ages and how much pain you feel!

In a new study led by Khalid Freij; Burel Goodin, alongside researchers at the University of Alabama at Birmingham, found that optimism was linked to less depression and slower aging, which in turn related to lower pain severity. Pessimism had the opposite effect!

The article, "Serial Mediation: How Optimism Reduces and Pessimism Intensifies Chronic Low Back Pain Through Depression and Biological Aging" has been published in Biological Research for Nursing!

Older adults are turning to medical ma*****na more than ever, especially for chronic pain. However, there’s still a big gap in understanding its real benefits and risks. That’s where the SMILE study comes in!

This 12-month project, headed by Yan Wang, will follow 440 adults aged 50+ with chronic pain to track how it affects pain, physical function, emotional well-being, cognition, and quality of life. Researchers will collect data on this diverse group of individuals, consisting of some who use medical ma*****na and others who don't.

By the end, SMILE aims to give doctors, patients, and policymakers real-world evidence on whether medical ma*****na truly helps older adults in both short and long term as well as how to personalize its use for better outcomes.

Personalizing opioid prescriptions based on genetic testing and awareness of drug interactions might lead to better pain control and fewer emergency visits.

Researchers including Noor Nahid, Caitrin McDonough and Roger Fillingim found this out by looking at over 31,000 adults who were prescribed opioids that need to be processed by a specific liver enzyme called CYP2D6 (which helps turn these drugs into their active, pain-relieving forms). Some people naturally have lower CYP2D6 activity due to their genes, and others can have it reduced by certain medications.

The study found that individuals with reduced activity of a liver enzyme called CYP2D6 (thanks to genetics or other meds) had more ER visits for pain even while on opioids.

Find out more in the article, "CYP2D6 Phenotypes and Emergency Department Visits Among Patients Receiving Opioid Treatment" which has been published in JAMA Network Open!
