Abstract
Opioids prescribed for pain and migraine can produce opioid-induced hyperalgesia (OIH) or medication overuse headache (MOH). We previously demonstrated that pituitary adenylate cyclase activating polypeptide (PACAP) is upregulated in OIH and chronic migraine models. Here we determined if PACAP acts as a bridge between opioids and pain chronification. We tested PACAP-PAC1 receptor inhibition in novel models of opioid-exacerbated trigeminovascular pain. The PAC1 antagonist, M65, reversed chronic allodynia in a model which combines morphine with the migraine trigger, nitroglycerin. Chronic opioids also exacerbated cortical spreading depression, a correlate of migraine aura; and M65 inhibited this augmentation. In situ hybridization showed MOR and PACAP co-expression in trigeminal ganglia, and near complete overlap between MOR and PAC1 in the trigeminal nucleus caudalis and periaqueductal gray. PACAPergic mechanisms appear to facilitate the transition to chronic headache following opioid use, and strategies targeting this system may be particularly beneficial for OIH and MOH.

Abstract
OBJECTIVES This study aimed to determine the rate and context in which opioids are used to treat migraine in adolescents and young adults seen in emergency care settings. METHODS Data from 2010 to 2016 in the Cerner Health Facts electronic health record data warehouse were analyzed using multilevel logistic regression to estimate the population likelihood of an opioid being used in the emergency department (ED) to treat a primary diagnosis of migraine in adolescents and young adults and to evaluate the extent to which this likelihood varies as a function of characteristics of the patient (age, sex, race, and insurance), encounter (referral source, provider specialty, and encounter duration and year), and ED (region, setting, size, payer mix, and academic status). RESULTS The study identified 14,494 eligible ED encounters with unique patients, of which 23% involved an opioid. Likelihood of being treated with opioids was significantly higher for patients who were older, female, white, and seen by a surgeon and who had longer encounters and encounters earlier in the time period sampled. Sites varied widely in percentage of encounters involving opioids (mean, 26.4% ± 20.1%; range, 0-100%), with higher rates associated with smaller sites with relatively higher proportions of commercially insured patients. CONCLUSIONS Use of opioids in the ED to treat migraine in youth is fairly common, with rate variation reflecting broader trends in for whom opioids tend to be more likely to be prescribed. These findings may be helpful for benchmarking and informing quality improvement efforts aimed at reducing unwarranted opioid exposure in youth.

Abstract
BACKGROUND: Migraine is a common neurological disease that can have a substantial impact on patients' lives and on society. Erenumab, a fully human monoclonal antibody that targets the calcitonin gene-related peptide receptor, was specifically developed for migraine prevention. The efficacy of erenumab has been established in several clinical trials; however, the real-world comparative effectiveness of erenumab has not been fully investigated. OBJECTIVE: To evaluate the real-world impact of erenumab and onabotulinumtoxinA on acute medication usage and health care resource utilization (HCRU) among patients with migraine in the United States. METHODS: This retrospective US claims analysis (Optum's deidentified Clinformatics Data Mart Database) evaluated patients aged at least 18 years diagnosed with migraine who initiated erenumab or onabotulinumtoxinA between May 1, 2018, and September 30, 2019 (index date: first erenumab/onabotulinumtoxinA claim). Cohorts were matched 1:1 using the propensity score (PS) method (greedy match with caliper = 0.1). Stratification was performed based on gender, chronic migraine without aura diagnosis, onabotulinumtoxinA use, and acute/preventive drug use. The impact of erenumab and onabotulinumtoxinA on acute medication usage and HCRU was assessed in the 6-month post-index period. An exploratory analysis assessed the impact of erenumab and onabotulinumtoxinA on a composite endpoint of: (1) outpatient visit with a migraine diagnosis and associated acute medication claim, (2) hospital admission with a primary migraine diagnosis, or (3) emergency department visit with a primary migraine diagnosis. PS-matched data were used for comparative analyses; logistic regression with covariate adjustment was used for dichotomous variables, and a negative binomial model was used for count variables, with odds ratios or rate ratios (RRs) and 95% CIs calculated. RESULTS: Following stratified PS matching, 1,338 patients were included in both cohorts. At 6 months, the adjusted average number of claims per person for any acute medication was significantly lower in the erenumab cohort (1.13 vs 1.29 in the onabotulinumtoxinA cohort; RR = 0.88; 95% CI = 0.80-0.96; P = 0.0069), although the difference in the number of claims for triptans and barbiturates was statistically nonsignificant. The adjusted average number of all-cause and migraine-specific visits per person to health care providers was generally lower in the erenumab cohort compared with the onabotulinumtoxinA cohort. Patients in the erenumab cohort had a significantly lower number of composite events (0.44 vs 0.69 in the onabotulinumtoxinA cohort; RR = 0.63; 95% CI = 0.56-0.71; P < 0.0001). Similarly, the adjusted proportion of patients with any of the 3 composite events was lower in the erenumab cohort (31.7% vs 44.3% in the onabotulinumtoxinA cohort; OR = 0.59; 95% CI = 0.49-0.70; P < 0.0001). CONCLUSIONS: In this retrospective claims analysis study, erenumab significantly reduced acute medication usage (opioids and nonsteroidal anti-inflammatory drugs; any acute medication when analyzed together) and HCRU to a greater extent than onabotulinumtoxinA.

Abstract
OBJECTIVE Increasingly, patients are seeking same-day care at urgent care (UC) facilities. Little is known about the health care utilization patterns of patients who visit UC facilities for headache and migraine. We examined the frequency of headache and migraine visits and revisits at UC facilities. METHODS We conducted a retrospective cohort study of headache not otherwise specified (NOS) and migraine visits from 67 NYC UC facilities over an eight-month period. We report descriptive analyses, the frequency of headache NOS revisits, and the elapsed time to revisits. RESULTS There were 10,240 patients who visited UC facilities for headache NOS or migraine within the eight-month period. The majority of patients, 6,994 (68.3%), were female, and the mean age (SD) was 35.1 (15.0) years. Most (93.9%) patients (N = 9,613) lived within 60 miles of NYC; 5.5% (N = 564) had at least one revisit, and among re-visitors, there was an average (SD) of 2.2 (0.7) visits to UC facilities during the study period and an average time to revisit (SD) of 61.3 (55.2) days. CONCLUSIONS In just eight months, there were >10,000 headache NOS and migraine visits to UC facilities in NYC, with half of revisits occurring within 90 days. Future work should examine headache management in UC facilities.

Abstract
OBJECTIVE To examine the safety and efficacy of ubrogepant for acute treatment of migraine across cardiovascular (CV) disease risk categories. METHODS ACHIEVE I and II were multicenter, double-blind, single-attack, phase 3 trials in adults with migraine, with or without aura. Participants were randomized 1:1:1 to placebo or ubrogepant (50 or 100 mg in ACHIEVE I; 25 or 50 mg in ACHIEVE II), to treat one migraine attack of moderate or severe headache pain intensity. This post-hoc analysis pooled data from ubrogepant 50 mg and placebo groups from the ACHIEVE trials to examine the safety and efficacy of ubrogepant by baseline cardiovascular disease risk factors. Using a cardiovascular risk assessment algorithm, participants were categorized as having no cardiovascular risk, low cardiovascular risk or moderate-high cardiovascular risk at baseline. Treatment-emergent adverse events were documented 48 h and 30 days after taking the trial medication. Co-primary efficacy outcomes were 2-h pain freedom and 2-h absence of most bothersome migraine-associated symptom. RESULTS Overall, 3358 participants were randomized in the ACHIEVE trials (n = 2901 safety population; n = 2682 modified intent-to-treat population). In the safety population, 11% of participants were categorized as moderate-high (n = 311), 32% low (n = 920), and 58% no cardiovascular risk factors (n = 1670). The proportion of ubrogepant participants reporting a treatment-emergent adverse event was comparable across risk categories and similar to placebo. The treatment effects of ubrogepant versus placebo were consistent across cardiovascular risk categories for all efficacy outcomes. CONCLUSION The safety and efficacy of ubrogepant for the acute treatment of a single migraine attack did not differ by the presence of major cardiovascular risk factors. No evidence of increased treatment-emergent adverse events or cardiac system organ class adverse events with ≥2 major cardiovascular risk factors and no safety concerns were identified.Trial Registration: ACHIEVE I ClinicalTrials.gov number, NCT02828020; ACHIEVE II ClinicalTrials.gov number, NCT02867709.

Abstract
OBJECTIVE We sought to assess factors associated with the frequency of self-reported prescription opioid use in persons with migraine, including demographic variables, comorbidities, headache characteristics, and patterns of consultation. BACKGROUND Despite the dose-dependent effect of opioids on migraine progression and the association with negative outcomes, migraine treatment often includes opioids. The Migraine in America Symptoms and Treatment Study focuses on individuals with migraine who receive prescription acute medications, including those receiving and those not receiving opioids. METHODS This web-based panel survey identified people in the United States with migraine using a validated screener. This analysis stratified people with migraine into 4 groups based on days of monthly opioid use: non-opioid users, ≤3 days, 4-9 days, and ≥10 days per month. RESULTS Of 15,133 respondents with migraine, 4701 (31%) reported acute prescription medication use for headache/migraine in the previous 3 months (mean age 45 years, 71.6% [3367/4701] female), of whom 32.5% (1528/4701) reported opioid use. About one-third of respondents with primary care or neurology consults in the prior 6 months reported receiving an opioid, and more than half of respondents (209/391, 53.5%) with a pain clinic consultation did so. Models compared those using opioids ≤3 days/month (879/4701, 18.7%), 4-9 days/month (304/4701, 6.5%), ≥10 days/month (345/4701, 7.3%) to non-opioid users (3173/4701, 67.5%). Compared to non-opioid users, infrequent users (≤3 days/month) were more likely to be male and less likely to have chronic migraine or to screen positive for anxiety and depression; and frequent opioid users (the 4-9 days/month and the ≥10 days/month groups) were more likely to be male, to smoke, to be obese, to report greater pain interference, to have moderate to severe disability, to have symptoms of anxiety and depression, to use fewer triptans and nonsteroidal anti-inflammatory drugs, and to have poor acute treatment optimization. CONCLUSION Among prescription medication users, this cross-sectional analysis shows that increasing use of prescription opioids is associated with male gender, chronic migraine, more severe disability, anxiety and depression, poor acute treatment optimization, and treatment in a pain clinic.

Abstract
The American College of Emergency Physicians (ACEP) published guidelines in July 2019 on the diagnosis and management of acute nontraumatic headaches in the emergency department, focusing predominantly on the diagnosis of subarachnoid hemorrhage and the role of imaging and lumbar puncture in diagnosis. The ACEP Clinical Policies document is intended to aide Emergency Physicians in their approach to patients presenting with acute headache and to improve the accuracy of diagnosis, while promoting safe patient care practices. The Clinical Policies document also highlights the need for future research into best practices to distinguish primary from secondary headaches and the efficacy and safety of current treatment options for acute headaches. The following commentary on these guidelines is intended to support and expand on these guidelines from the Headache specialists' perspective, written on behalf of the Refractory, Inpatient, Emergency Care section of the American Headache Society (AHS). The commentary have been reviewed and approved by Board of Directors of the AHS.

Abstract
Migraines are consistently among the top 20 primary coded diagnoses in emergency departments, constituting 4.5% of all chief complaints. In a significant subset of these, pain arises from the occipital region innervated by the greater (GON) and lesser occipital nerve. In this case series, we present three patients with occipital migraines who received GON blockade with 1% lidocaine. The blockade was performed only after first-line treatment with metoclopramide and possibly additional medications as ordered by triage physician, failed to adequately alleviate pain by 40 minutes after medication administration. Patients were contacted a minimum of seven days following treatment. All three patients experienced significant analgesia and relief of symptoms within 15 minutes of blockade and sustained relief through a seven-day follow-up period.

Abstract
Treatment of headache, specifically migraine attacks, has always been a challenging subject, especially for neurologist and pain specialists. Triptans are generally underutilized, despite being the gold standard abortive medication for migraine attacks. On the other hand, opioid analgesics are overused as a treatment for headache. One reason for this could be physician unfamiliarity with drug interactions between opioids and other medications, especially the possibility of serotonin toxicity. The general awareness of potential serotonin toxicity with using opioid analgesics is low. In this review, we will conduct a theoretic and evidence-based review of the potential for developing serotonin syndrome in patients who are using opioids analgesics, especially in combination with antidepressants, a common co-prescribed combination. We also review the current diagnostic criteria for serotonin syndrome and identify possible shortcomings of those criteria. Our aim is to increase the awareness of health care providers about potential drug interaction of opioid analgesics with other classes of medication. We place particular emphasis on tramadol since this drug is one of the most commonly used opioid analgesics for headache. The potential for developing serotonin syndrome is relatively high in the patients who are using opioid for pain control. The use of opioids in migraine headache is already discouraged due to the high risk of medication overuse headache and also an increase in headache-related disability (Katsarava et al. Neurology 62:788-790, 2004; Bigal and Lipton. Neurology 71:1821-8, 2008; Casucci and Cevoli. Neurol Sci. 34 Suppl 1:S125-8, 2013). This is another reason that physicians and health care providers should avoid using this class of medication for pain, specifically headache and migraine treatment.

Abstract
OBJECTIVE To develop and implement an algorithm for the management of headaches presenting to the emergency department (ED) in order to decrease the frequency of opioid and barbiturate treatment both acutely as well as on discharge. BACKGROUND Headache is the fifth leading cause of ED visits in the United States. In the case of primary headache, particularly migraine, treatment in the ED can be highly variable. Patients with migraine continue to be treated with opioids more commonly than nonopioid, migraine specific medications. In addition, discharge plans seldom include measures to prevent recurrence or instructions to re-treat if pain persists. At this time, there is no standardized management protocol directed at acute headaches presenting to the ED. METHODS An ED headache treatment algorithm with step-wise instructions for diagnosis, treatment, and discharge planning was piloted at Lakewood Hospital, a regional Cleveland Clinic affiliated hospital. This non-randomized interventional study compared outcomes after implementation of the algorithm to historical controls. Patient demographic data including age, gender, and payer mix was collected. Outcomes measured included the frequency of treatment with opioids or barbiturates, imaging, neurology consults, admissions, and a patient reported pain score. Data relevant to patient disposition and follow-up, including prescriptions for opioids or barbiturates given at discharge, and ensuring PCP or neurology follow-up appointments at discharge was also reviewed. RESULTS Demographic data did not differ significantly between the pre- and post-algorithm groups. There was a significant decline in the number of patients treated with opioids and barbiturates from 66.0% pre-algorithm to 6.8% immediately after algorithm implementation (P <. 001), and to 28% (P < .001) one year after algorithm implementation, indicating both an immediate effect of the algorithm and a sustained effect. Similarly, pre-algorithm implementation, 37% of patients were discharged with a prescription for opioids or barbiturates as compared to 12% and 6% in the early post-algorithm cohort and at 1 year, respectively. There was also an increase in scheduled follow-up appointments after discharge from the ED from 59% to 98% immediately post algorithm (P < .001). Other measures including the frequency of imaging, and patient reported pain did not significantly change. There was a significant increase in neurology consults and admissions a year after the algorithm was implemented. CONCLUSIONS A quality improvement pilot study aimed at treating headache in an Emergency Department setting was successfully implemented in a regional Cleveland Clinic Hospital. Our results demonstrated significant decrease in acute treatment with opioids or barbiturates and a decrease in prescriptions written for opioids or barbiturates on discharge. This study is limited by small sample size. More data are needed to determine the reason for 1) increased consultation and subsequent admission after algorithm implementation and 2) decreased scheduled follow-up appointments at one-year post algorithm.
