Many malignant cancers, including breast cancer, have a propensity to invade bones, leading to excruciating bone pain. Opioids are the primary analgesics used to alleviate this cancer-induced bone pain (CIBP) but are associated with numerous severe side effects, including enhanced bone degradation, which significantly impairs patients' quality of life. In contrast, agonists activating only peripheral CB1 receptors (CB1Rs) have been shown to effectively alleviate multiple chronic pain conditions with limited side effects, yet no studies have evaluated their role(s) in CIBP...

Pain and fatigue are the most common problems reported by women in the early postpartum period. Pain can interfere with a woman's ability to care for herself and her infant. Untreated pain is associated with a risk of greater opioid use, postpartum depression, and development of persistent pain. Nonpharmacologic and pharmacologic therapies are important components of postpartum pain management. Because 81% of women in the United States initiate breastfeeding during the postpartum period, it is important to consider the drug effects of all prescribed medications on the mother-infant dyad...

Screening for opioid use disorder should be considered in chronic non-cancer pain (CNCP) patients with long-term use of opioids. The aim of our study was to assess the effectiveness of an individualized treatment plan (ITP) for prescription opioid dependence that included screening of pharmacogenetic markers. An observational prospective study was performed using prescription opioid-dependent CNCP outpatients (n = 88). Patients were divided into nonresponders, responders, or high responders according to their response to the ITP...

Recent studies have shown that persistent pain facilitates the response to morphine reward. However, the circuit mechanism underlying this process remains ambiguous. In this study, using chronic constriction injury (CCI) of the sciatic nerve in mice, we found that persistent neuropathic pain reduced the minimum number of morphine conditioning sessions required to induce conditioned place preference (CPP) behavior. This dose of morphine had no effect on the pain threshold. In the medial prefrontal cortex (mPFC), which is involved in both pain and emotion processing, corticotropin-releasing factor (CRF) expressing neuronal activity was increased in CCI mice...

Activation of the cholecystokinin type B receptor (CCKBR) by cholecystokinin octapeptide (CCK-8) inhibits opioid analgesia. Chronic opiate treatment leads to an increase in the CCK-8 concentration and thus enhances the antagonism of CCK-8 against opioid analgesia; the underlying molecular mechanisms remain of great interest. In the present study, we validated the colocalization of the μ-opioid receptor (MOR) and CCKBR in pain signal transmission-related spinal cord dorsal horn and dorsal root ganglion neurons of rats...

Older adults who take analgesics for chronic pain are at increased risk for adverse drug events (ADEs). The purpose of this descriptive pilot survey was to examine how older adults self-identify analgesic ADEs, and actions they take in response to analgesic ADEs. Twenty-two community dwelling older adults with chronic pain who reported an analgesic ADE associated with their chronic pain management were interviewed and asked to describe their analgesic related ADE. Written responses were content analyzed. Nineteen opioids were reported by 15, 11 NSAIDs were reported by 8, and acetaminophen was reported by 2 older adults as associated with an ADE...

High levels of pain, significant anxiety, and/or depressive symptoms prior to surgery put patients at elevated risk forchronic pain and prolonged opioid use following surgery. The purpose of this preliminary study was to assess the efficacy of a one-day Acceptance and Commitment Therapy (ACT) workshop in "at-risk" Veterans for the prevention of chronic pain and opioid use following orthopedic surgery. In a randomized controlled trial, 88 at-risk Veterans undergoing orthopedic surgery were assigned to Treatment as Usual (TAU; N =44) or TAU plus a 1-day ACT workshop (N = 44)...

Acute mesenteric ischemia is a highly morbid affliction which requires urgent care. Acute mesenteric ischemia consists in an ischemia injury of the small bowel, secondary to vascular insufficiency, either occlusive (thrombosis, embolism, arterial, venous) or non-occlusive (low flow or vasospasm). Given that the superior mesenteric artery supplies the small bowel as well as the right part of the colon, any ischemic process involving the right colon should be considered an acute mesenteric ischemia until proven otherwise...

Latent sensitization is a model of chronic pain in which an injury triggers a period of hyperalgesia followed by an apparent recovery, but in which pain sensitization persists but is suppressed by opioid and adrenergic receptors. One important characteristic of latent sensitization is that hyperalgesia can be triggered by acute stress. To determine whether the effect of stress is mimicked by the activation of corticotropin-releasing factor (CRF) signaling in the brain, rats with latent sensitization induced by injecting complete Freund's adjuvant (CFA, 50 μl) in one hind paw were given an intracerebroventricular (i...

Pain is highly prevalent among the adult Latin American population. However, many patients with moderate to severe pain do not have access to effective pain management with opioids due to limited access to healthcare, overuse of nonopioid analgesics, regulatory barriers and lack of appropriate information about opioids. There is scarce training on use of opioids among physicians and other healthcare providers, which leads to misconceptions, mainly related to a fear of prescribing opioids. Although opioids are safe and effective drugs for the treatment of moderate to severe chronic pain, the use of opioids in Latin American nations is clearly below standards compared with developed countries...

Exercise-induced analgesia is a phenomenon discussed worldwide. This effect began to be investigated in the early 1970s in healthy individuals and rodents during and after an acute or chronic session of running or swimming. Thereafter, studies found this effect was also induced by resistance exercises. Over the years, many studies have demonstrated the importance of exercise-induced analgesia in relieving pain caused by different conditions, such as fibromyalgia, low back pain, neuropathy, and osteoarthritis...

Introduction: Opioids have been used for millennia for the treatment of pain. However, the long-term efficacy of opioids to treat chronic non-cancer pain continues to be debated. To evaluate opioids' efficacy in chronic non-cancer pain, we performed a meta-analysis of published clinical trials for μ-opioid receptor agonists performed for US Food and Drug Administration approval. Methods: MEDLINE and Cochrane trial register were searched for enriched enrollment randomized withdrawal studies (before June 2016)...

Background: There is limited real-world, population-level data on the prevalence and treatment of pain in children. An understanding of pediatric pain conditions and its management can help inform provider education, treatment guidelines, and design of pediatric pain studies. Therefore, in this study, we aimed to describe the prevalence of conditions associated with acute and chronic pain in pediatric patients and to characterize pediatric pain treatment with nonsteroidal anti-inflammatory drugs, cyclooxygenase-2 (COX-2) inhibitors, opioids (immediate release or extended release), antidepressants, topical analgesics, anticonvulsants, and other therapies based on a large, real-world sample...

Chronic pelvic pain(CPP) is a common condition in women that can have a devastating effect on quality of life. Some of the most severe forms of CPP are related to peripheral nerve injuries causing persistent neuropathic pain. This is a case of a young woman with severe opioid dependent chronic pelvic and right groin pain due to obturator neuralgia. She had failed a multitude of treatments including multiple medications, manual physical therapy, nerve blocks, surgical neurolysis and spinal cord stimulation without significant benefit...

Opioid misuse is regularly associated with disrupted functioning in those with chronic pain. Less work has examined whether alcohol misuse may also interfere with functioning. This study examined frequency of opioid and alcohol misuse in 131 individuals (61.1% female) prescribed opioids for the treatment of chronic pain. Participants completed an anonymous survey online, consisting of measures of pain, functioning, and opioid and alcohol misuse. Cut-scores were used to categorize individuals according to substance misuse status; individuals were categorized as follows: 35...
