Prescription-related opioid misuse, especially in chronic pain populations, is an ongoing problem and is related to increased mortality. The purpose of this study was to assess the utility of two restructured scales of the MMPI-2-RF: the Personality Psychopathology Five (PSY-5-RF) and the Higher-Order Scales to determine which of their subscales may be beneficial for identifying the risk of opioid misuse in a chronic pain population. A sample of 136 patients with chronic disabling occupational musculoskeletal disorders completed the MMPI-2-RF and the Current Opioid Misuse Measure (COMM) upon admission to a functional restoration program. The PSY-5-RF and H-O subscales were correlated with the baseline COMM scores. Correlation analyses, ROC curve analyses, and multiple binary logistic regression models were developed to determine which subscales were most associated with elevated COMM scores. The results of the regression analyses suggest that Scale elevations on two of the PSY-5-RF Scales and two Higher-Order Scales of the MMPI-2-RF demonstrated significant associations with elevated COMM scores, thus exhibiting the utility of these subscales in identifying the risk of opioid misuse among chronic pain patients. These findings are clinically meaningful in underscoring the importance of identifying specific personality traits as potential predictors of opioid misuse, and identifying those at risk through careful screening. Clinical implications based on each of the PSY-5-RF and H-O scales significantly associated with elevated COMM scores are discussed.

Learn More >The appropriate recognition and assessment of pain in animals is an essential tool that can be used by veterinary professionals, rehabilitators, household caregivers, and others to provide supportive care and analgesia to patients. Although the use of behavioral, postural, and facial changes to recognize pain have been studied in popular domestic species such as dogs (), cats (), and rabbits (), very little is known relative to avian species. The purpose of this article is to provide a literature review comprising structured searches on the topic of avian pain recognition. The emphasis of the searches were based on the behavioral and postural alterations that have thus far been explored. The literature review was performed in the months of August-September 2020 over 5 online databases: MEDLINE/ PubMed, CAB Direct, Biosis, Zoological Record, and Scopus. Additional "snowballing" was incorporated by looking at the references and articles that cited the 126 articles from the initial abstract and full-text screening. Of the 194 full-text articles reviewed, 132 sources of literature were included in the final analysis. From these 132 sources of literature, 31.8% were general review articles in which avian pain behaviors were described irrespective of species, with others being specific to a particular species (chickens 47.8%, turkeys 7.6%, parrots 3.8%, pigeons [] 3%, raptors 3%, and "other" 3%-2 on ducks, 1 on emus [], and 1 on Eurasian blue tits []). Pain stimulus varied depending on species, although the vast majority of the pain stimuli involved welfare issues such as beak trimming, limb abnormalities, and keel bone fractures in chickens. Although information regarding this topic remains limited for many avian species, this review provides a more thorough understanding of behavioral indicators of pain in species such as chickens, turkeys, psittacines, pigeons, raptors, and select others. It is the hope that this review will motivate further interest and future analgesia research for the improvement of avian welfare.
Learn More >The COVID-19 pandemic resulted in a novel challenge for healthcare delivery and implementation in the United States (US) in 2020 and beyond. Telemedicine arose as a significant and effective medium for safe and efficacious physician-patient interactions. Prior to the COVID-19 pandemic, telemedicine while available, had infrequently been utilized in pain medicine practices due to difficulties with reimbursement, the learning curve associated with new technology usage, and the need for new logistical systems in place to implement telemedicine effectively. Given the unique constraints on the healthcare system during the COVID-19 pandemic, the ubiquitous utilization of telemedicine among pain medicine physicians increased, giving insight into potential future roles for the technology beyond the pandemic.
Learn More >Neonatal maternal separation (NMS), a major kind of early life stress, increases the risk of visceral pain, anxiety- and depression-like behaviors in adulthood. An enriched environment (EE) has been shown to successfully rescue the brain from various early life psychological stressors. Therefore, this study aimed to investigate whether NMS induces visceral pain, anxiety- and depression-like behaviors in adolescents and to evaluate the impact of EE in infancy on these symptoms.
Learn More >Complementary and integrative health (CIH) approaches have gained empirical support and are increasingly being utilized among veterans to treat a myriad of conditions. A cluster of medically unexplained chronic symptoms including fatigue, headaches, joint pain, indigestion, insomnia, dizziness, respiratory disorders, and memory problems, often referred to as Gulf War Illness (GWI) prominently affect US Gulf War era (GWE) veterans, yet little is known about CIH use within this population. Using data collected as part of a larger study (n = 1153), we examined the influence of demographic characteristics, military experiences, and symptom severity on CIH utilization, and utilization differences between GWE veterans with and without GWI. Over half of the sample (58.5%) used at least one CIH modality in the past six months. Women veterans, white veterans, and veterans with higher levels of education were more likely to use CIH. GWE veterans with a GWI diagnosis and higher GWI symptom severity were more likely to use at least one CIH treatment in the past six months. Over three quarters (82.7%) of veterans who endorsed using CIH to treat GWI symptoms reported that it was helpful for their symptoms. Almost three quarters (71.5%) of veterans indicated that they would use at least one CIH approach if it was available at VA. Results provide a deeper understanding of the likelihood and characteristics of veterans utilizing CIH to treat health and GWI symptoms and may inform expansion of CIH modalities for GWE veterans, particularly those with GWI.
Learn More >This clinical trial investigated the effect of an Emotional Freedom Techniques (EFT) intervention on brain activation in chronic pain sufferers using functional magnetic resonance imaging (fMRI). EFT is a brief stress reduction technique which combines stating a cognitive statement with somatic tapping on acupressure points. Twenty-four adults were allocated to a six-week online group EFT treatment and underwent resting-state fMRI pre and post the intervention. A repeated measures MANOVA indicated significant differences in the levels of pain severity (-21%), pain interference (-26%), quality of life (+7%), somatic symptoms (-28%), depression (-13.5%), anxiety (-37.1%), happiness (+17%), and satisfaction with life (+8.8%) from pre-to post-test. Cohen's effect sizes ranged from small (0.2) to large (0.75) values suggesting significance for the intervention. fMRI analysis showed post-EFT treatment significantly decreased connectivity between the medial prefrontal cortex (a pain modulating area) and bilateral grey matter areas in the posterior cingulate cortex and thalamus, both areas being related to modulating and catastrophizing of pain. There were no brain areas that showed significantly increased connectivity post-EFT treatment. Coupled with the psychological measures the findings support the effects of the EFT intervention in reducing chronic pain and its impacts. Recommendations for future research are discussed.
