Eat, Sleep, Console Approach or Usual Care for Neonatal Opioid Withdrawal.

BACKGROUND: Although clinicians have traditionally used the Finnegan Neonatal Abstinence Scoring Tool to assess the severity of neonatal opioid withdrawal, a newer function-based approach - the Eat, Sleep, Console care approach - is increasing in use. Whether the new approach can safely reduce the time until infants are medically ready for discharge when it is applied broadly across diverse sites is unknown. METHODS: In this cluster-randomized, controlled trial at 26 U.S. hospitals, we enrolled infants with neonatal opioid withdrawal syndrome who had been born at 36 weeks' gestation or more. At a randomly assigned time, hospitals transitioned from usual care that used the Finnegan tool to the Eat, Sleep, Console approach. During a 3-month transition period, staff members at each hospital were trained to use the new approach. The primary outcome was the time from birth until medical readiness for discharge as defined by the trial. Composite safety outcomes that were assessed during the first 3 months of postnatal age included in-hospital safety, unscheduled health care visits, and nonaccidental trauma or death. RESULTS: A total of 1305 infants were enrolled. In an intention-to-treat analysis that included 837 infants who met the trial definition for medical readiness for discharge, the number of days from birth until readiness for hospital discharge was 8.2 in the Eat, Sleep, Console group and 14.9 in the usual-care group (adjusted mean difference, 6.7 days; 95% confidence interval [CI], 4.7 to 8.8), for a rate ratio of 0.55 (95% CI, 0.46 to 0.65; P<0.001). The incidence of adverse outcomes was similar in the two groups. CONCLUSIONS: As compared with usual care, use of the Eat, Sleep, Console care approach significantly decreased the number of days until infants with neonatal opioid withdrawal syndrome were medically ready for discharge, without increasing specified adverse outcomes.

Factors associated with discharge against medical advice in alcohol withdrawal patients.

This study aimed to examine characteristics associated with discharge against medical advice from the hospital in alcohol withdrawal patients, supporting the work of hospital staff and Alcohol Care Teams and identifying characteristics that may help target patients most likely to discharge against medical advice. We used Hospital Episode Statistics Data to identify demographic and clinical variables and compare these in alcohol withdrawal patients who discharged against medical advice from hospital, compared with those who were discharged by the clinical team. Factors significantly associated with alcohol withdrawal patients discharging against medical advice from hospital were: being admitted as an emergency; discharged on a weekend; living with no fixed abode; being male; being younger and having a shorter length of stay. This study identifies characteristics that can be used to support acute hospitals and Alcohol Care Teams, particularly in the allocation of resources to reduce discharges against medical advice and subsequent readmissions to the hospital. Particular consideration should be given to clinical provision in hospitals in emergency departments and on weekends, and also those patients who are admitted and are of no fixed abode.

Factorial, Construct, and Predictive Validity of the Motivation for Treatment Scale in Alcohol-Use Disorder Withdrawal Treatment.

INTRODUCTION: The aim of the present study was to examine for the first time the factorial, construct, and predictive validity of the motivation for treatment (MfT) scale in a cohort of patients undergoing inpatient-qualified alcohol withdrawal treatment with the goal of referring patients to further treatment. The MfT scale has previously been evaluated in different settings of substance abuse treatment, revealing factorial ambiguity. To the best of our knowledge, the present study is the first study that conducted comprehensive factor analyses versus separate analyses of the factors conducted in prior studies in order to clarify the aforementioned factorial ambiguity. METHODS: A total of 249 patients (mean age 45.2 years (SD = 10.3); 34.4% females) with alcohol dependence were assessed. Data were obtained from four inpatient clinics specialized in qualified alcohol withdrawal treatment in Germany. First, confirmatory factor analyses were carried out to examine the fit of the four models discussed in the literature. Second, an exploratory factor analysis was conducted. Correlations of the new factors with other motivational constructs and referral to a subsequent treatment were investigated as measures of construct and predictive validity. RESULTS: None of the four models showed an acceptable fit to the data in confirmatory analyses. The exploratory analysis suggested to eliminate seven items because of inappropriate factor loadings and resulted in a shortened MfT scale, which consists of three factors based on 17 items. For the latent variables "problem recognition," "desire for help," and "treatment readiness," satisfactory composite reliability was found with 0.82, 0.80, and 0.78, respectively. Evidence for predictive validity was found in the correlation between "treatment readiness" and referral to a subsequent treatment. DISCUSSION/CONCLUSION: The new shortened MfT scale exhibited remarkable parsimony, which is desirable in settings such as withdrawal treatment, where patients frequently are cognitively or physically impaired. Despite its briefness, construct and predictive validity were better than in the original version of the MfT scale. The factorial validity of the suggested scale needs to be corroborated in further research.

A Testimony of Christian Drug Rehabilitation: Transformed by the Power of God.

ABSTRACT: Drug addiction is at crisis level in the United States. Nurses caring for persons affected by substance use disorder (SUD) have a resource in Mr. Ming Ho Liu's testimony on Good TV (Taiwan)-translated and summarized in this article-of his addiction experiences and successful treatment at Operation Dawn, a Christian drug rehabilitation center. Recovery from SUD is possible by God's power. In Mr. Liu's case, his recovery was accomplished without medication.

Maternal and iatrogenic neonatal opioid withdrawal syndrome: Differences and similarities in recognition, management, and consequences.

Opioids are potent analgesics used to manage pain in both young and old, but the increased use in the pregnant population has significant individual and societal implications. Infants dependent on opioids, either through maternal or iatrogenic exposure, undergo neonatal opioid withdrawal syndrome (NOWS), where they may experience withdrawal symptoms ranging from mild to severe. We present a detailed and original review of NOWS caused by maternal opioid exposure (mNOWS) and iatrogenic opioid intake (iNOWS). While these two entities have been assessed entirely separately, recognition and treatment of the clinical manifestations of NOWS overlap. Neonatal risk factors such as age, genetic predisposition, drug type, and clinical factors like type of opioid, cumulative dose of opioid exposure, and disease status affect the incidence of both mNOWS and iNOWS, as well as their severity. Recognition of withdrawal is dependent on clinical assessment of symptoms, and the use of clinical assessment tools designed to determine the need for pharmacotherapy. Treatment of NOWS relies on a combination of non-pharmacological therapies and pharmacological options. Long-term consequences of opioids and NOWS continue to generate controversy, with some evidence of anatomic brain changes, but conflicting animal and human clinical evidence of significant cognitive or behavioral impacts on school-age children. We highlight the current knowledge on clinically relevant recognition, treatment, and consequences of NOWS, and identify new advances in clinical management of the neonate. This review brings a unique clinical perspective and critically analyzes gaps between the clinical problem and our preclinical understanding of NOWS.

A thalamic input to the nucleus accumbens mediates opiate dependence.

Chronic opiate use induces opiate dependence, which is characterized by extremely unpleasant physical and emotional feelings after drug use is terminated. Both the rewarding effects of a drug and the desire to avoid withdrawal symptoms motivate continued drug use, and the nucleus accumbens is important for orchestrating both processes. While multiple inputs to the nucleus accumbens regulate reward, little is known about the nucleus accumbens circuitry underlying withdrawal. Here we identify the paraventricular nucleus of the thalamus as a prominent input to the nucleus accumbens mediating the expression of opiate-withdrawal-induced physical signs and aversive memory. Activity in the paraventricular nucleus of the thalamus to nucleus accumbens pathway is necessary and sufficient to mediate behavioural aversion. Selectively silencing this pathway abolishes aversive symptoms in two different mouse models of opiate withdrawal. Chronic morphine exposure selectively potentiates excitatory transmission between the paraventricular nucleus of the thalamus and D2-receptor-expressing medium spiny neurons via synaptic insertion of GluA2-lacking AMPA receptors. Notably, in vivo optogenetic depotentiation restores normal transmission at these synapses and robustly suppresses morphine withdrawal symptoms. This links morphine-evoked pathway- and cell-type-specific plasticity in the paraventricular nucleus of the thalamus to nucleus accumbens circuit to opiate dependence, and suggests that reprogramming this circuit holds promise for treating opiate addiction.

Research Needs for Inpatient Management of Severe Alcohol Withdrawal Syndrome: An Official American Thoracic Society Research Statement.

Background: Severe alcohol withdrawal syndrome (SAWS) is highly morbid, costly, and common among hospitalized patients, yet minimal evidence exists to guide inpatient management. Research needs in this field are broad, spanning the translational science spectrum. Goals: This research statement aims to describe what is known about SAWS, identify knowledge gaps, and offer recommendations for research in each domain of the Institute of Medicine T0-T4 continuum to advance the care of hospitalized patients who experience SAWS. Methods: Clinicians and researchers with unique and complementary expertise in basic, clinical, and implementation research related to unhealthy alcohol consumption and alcohol withdrawal were invited to participate in a workshop at the American Thoracic Society 2019 International Conference. The committee was subdivided into four groups on the basis of interest and expertise: T0-T1 (basic science research with translation to humans), T2 (research translating to patients), T3 (research translating to clinical practice), and T4 (research translating to communities). A medical librarian conducted a pragmatic literature search to facilitate this work, and committee members reviewed and supplemented the resulting evidence, identifying key knowledge gaps. Results: The committee identified several investigative opportunities to advance the care of patients with SAWS in each domain of the translational science spectrum. Major themes included 1) the need to investigate non-γ-aminobutyric acid pathways for alcohol withdrawal syndrome treatment; 2) harnessing retrospective and electronic health record data to identify risk factors and create objective severity scoring systems, particularly for acutely ill patients with SAWS; 3) the need for more robust comparative-effectiveness data to identify optimal SAWS treatment strategies; and 4) recommendations to accelerate implementation of effective treatments into practice. Conclusions: The dearth of evidence supporting management decisions for hospitalized patients with SAWS, many of whom require critical care, represents both a call to action and an opportunity for the American Thoracic Society and larger scientific communities to improve care for a vulnerable patient population. This report highlights basic, clinical, and implementation research that diverse experts agree will have the greatest impact on improving care for hospitalized patients with SAWS.

Hyperbaric Oxygen Therapy for Pain, Opioid Withdrawal, and Related Symptoms: A Pilot Randomized Controlled Trial.

BACKGROUND: Pain, drug cravings, and opioid withdrawal symptoms can interfere with substance use disorder or opioid tapering treatment goals. AIM: This pilot study investigated the feasibility of a protocol designed to test opioid withdrawal symptom relief relative to a sham condition after two consecutive days of hyperbaric oxygen therapy (HBOT) for adults prescribed daily methadone for opioid use disorder. METHOD: Using a double-blind protocol, eight adults were randomized to receive either a full 90-minute HBOT dose in a pressurized chamber with 100% oxygen at 2.0 atmospheres absolute (ATA) or a sham condition receiving 21% oxygen (equivalent to room air within the chamber) at a minimal pressure of ≤1.3 ATA. Measures included study retention, treatment satisfaction, and pre- and post-intervention effects for opioid withdrawal symptoms, drug cravings, pain intensity and interference, sleep quality, and mood. RESULTS: Study retention and treatment satisfaction was high. All measurements improved more, on average, for participants receiving full-dose HBOT treatment than among participants receiving sham treatments except for clinically observed withdrawal symptoms. The largest positive effects were observed in measurements of pain intensity and drug craving. CONCLUSIONS: These pilot results provide evidence to support a fully powered study of HBOT as a potential treatment adjunct for adults receiving methadone for opioid use disorder. Trends towards symptom improvements were detected from pre- to post-HBOT in the full treatment arm versus sham condition. More research into novel non-pharmacologic options to relieve distressing symptoms related to pain and opioid use disorder is essential to improve clinical outcomes.

A Cluster-Randomized Trial Comparing Songwriting and Recreational Music Therapy via Craving and Withdrawal in Adults on a Detoxification Unit.

BACKGROUND: Craving and withdrawal can contribute to the development and maintenance of substance use disorder (SUD), relapse, and overdose. Although music therapy can positively impact craving and withdrawal in adults with SUD on a detoxification unit, there is a lack of randomized research comparing different music therapy interventions as well as studies measuring within-session changes in these critical constructs. OBJECTIVE: The purpose of this effectiveness study was to compare motivational-educational songwriting (MESW) and recreational music therapy (RMT) via measures of craving and withdrawal in adults with SUD on a detoxification unit using a two-group pre- and posttest design. METHOD: Participants (N = 134) were cluster-randomized to a single group MESW or RMT condition. Established craving and withdrawal psychometric instruments were used as pre- and posttests to determine potential within- and between-group differences. RESULTS: There were significant within-group differences in craving subscales of urges and coping as well as withdrawal, all p < .001. Within-group effect sizes ranged from .244 to .456 with favorable changes from pre- to posttest. There was no between-group difference among the MESW and RMT conditions, all p > .05. CONCLUSIONS: Although the specific music therapy intervention did not impact craving or withdrawal, a single MESW or RMT session can have an immediate and significant positive impact on craving and withdrawal in adults with SUD on a detoxification unit. As the MESW condition also addressed motivational and educational aspects of recovery, perhaps MESW interventions are ideal in detoxification settings.

The Effects of Electroacupuncture via Chronically Implanted Electrodes on Alcohol Drinking and Withdrawal Signs in Rats.

BACKGROUND: In the United States, more than 14 million adults suffer from alcohol use disorder (AUD). We proposed a stress-free method of electroacupuncture (EA) using chronically implanted electrodes. We aimed to develop an effective method of EA for treating AUD by testing various stimulation locations and parameters, and then investigate the effects of the daily EA on alcohol consumption and withdrawal signs in rats. MATERIALS AND METHODS: Sprague-Dawley rats were trained to voluntarily drink ethanol under the intermittent access two-bottle choice procedure. By the end of four weeks, rats with ethanol consumption ≥1.5 g/kg/24 h were considered alcohol-dependent and included in an acute and prolonged experiments. The acute study was designed to investigate the effects of EA with different parameters and at different locations. EA treatment was applied at bilateral ST36 alone or bilateral ST36 and HT7 acupoints for 30 minutes. We investigated the effects of EA on 24-hour alcohol consumption, preference ratio (alcohol drink vs total drink), alcohol withdrawal signs (AWS), and prolonged alcohol consumption. Each animal served as its own control. RESULTS: 1) By the end of week 4, 70% of rats became alcohol-dependent. 2) Following ethanol withdrawal, there was a gradual increase in AWS over time that peaked at two hours and dropped at six hours. Among the tested stimulation parameters and locations: 3) The best stimulation location was ST36 alone, and the best stimulation parameters were a combination of 100 and 2 Hz. EA at best stimulation location and parameters reduced ethanol intake by 27% (p < 0.05 vs baseline) and marginally reduced preference ratio by 23% (p = 0.05 vs baseline). 4) EA reduced AWS at two- and four-hours following ethanol withdrawal (p ≤ 0.03 each vs no EA). 5) Daily EA (for five consecutive days) resulted in a substantial reduction in ethanol intake and preference ratio by 44% and 47%, respectively (p = 0.002 each). CONCLUSIONS: This work shows the potential of this novel method of EA for the treatment of AUD. Further studies are warranted to investigate the mechanisms through which EA exerts its effects.

[The Pharmacological Management of Emergencies in Child and Adolescent Psychiatry]. / Das pharmakologische Management kinder- und jugendpsychiatrischer Notfälle.

The Pharmacological Management of Emergencies in Child and Adolescent Psychiatry Abstract. Emergencies in child and adolescent psychiatry are highly prevalent and often pose significant challenges to physicians, since substantial danger to the patient or others must be avoided through the application of largely moderate interventions. Besides using de-escalating strategies and exploiting psychotherapeutic options, the physician frequently employs psychopharmacological interventions. because of a lack of systematically assessed data, however, in emergencies in child and adolescent psychiatry most administrations of psychotropic drugs occur "off label." This review deduces practice-relevant recommendations for the pharmacological management of occurring child and adolescent emergencies such as acute suicidality, acute psychotic episodes, delirium, disorders of consciousness, acute intoxication, and alcohol withdrawal syndrome. We discuss the issue of quality and safety in pharmacological emergency strategies.

The effect of daily aerobic cycling exercise on sleep quality during inpatient cannabis withdrawal: A randomised controlled trial.

Sleep disturbance is a common symptom encountered by cannabis-dependent individuals abstaining from cannabis use. In the present study, we investigated the effect of daily aerobic cycling exercise versus control stretching on sleep quality during inpatient cannabis withdrawal in treatment-seeking dependent cannabis users. The protocol incorporated three consecutive phases: a 4-Day (4-Night) (at-home) 'Baseline' phase, a 6-Day (5-Night) 'Treatment' phase (within a 7-Day inpatient hospital stay) and a 3-Day (4-Night) (at-home) 'Post-Treatment' phase. Participants performed 35 min of monitored activity per day during the Treatment phase. The intervention group (n = 19) cycled at ~60% aerobic capacity (VO2max ), while the control group (n = 12) performed a stretching routine. Objective sleep quality was measured nightly throughout the study using wrist actigraphy ratings of subjective sleep quality were also recorded during the Treatment phase. There were no group differences in sleep measures during the Baseline phase (all p > .05). Objective sleep onset latency increased from the Baseline to the Treatment phase in the control (stretching) group (p = .042). In contrast, the Cycling group exhibited improvements in sleep duration (p = .008) and sleep efficiency (p = .023) during the Treatment phase compared to the Baseline phase. Cycling also increased sleep duration (p = .005), decreased average wake bout (p = .040) and tended to increase sleep efficiency (p = .051) compared to stretching during the Treatment phase. Subjective sleep quality ratings did not differ between groups (p > .10). These preliminary findings suggest that moderate-intensity aerobic exercise may attenuate the sleep disturbances associated with cannabis withdrawal.

QuitNic: A Pilot Randomized Controlled Trial Comparing Nicotine Vaping Products With Nicotine Replacement Therapy for Smoking Cessation Following Residential Detoxification.

INTRODUCTION: The QuitNic pilot trial aimed to test the feasibility of providing a nicotine vaping product (NVP) compared with combination nicotine replacement therapy (NRT) to smokers upon discharge from a smoke-free residential substance use disorder (SUD) treatment service. METHODS: QuitNic was a pragmatic two-arm randomized controlled trial. At discharge from residential withdrawal, 100 clients received telephone Quitline behavioral support and either 12-week supply of NRT or an NVP. Treatment adherence and acceptability, self-reported abstinence, cigarettes smoked per day (CPD), frequency of cravings, and severity of withdrawal symptoms were assessed at 6 and 12 weeks. Results are reported for complete cases and for abstinence outcomes, penalized imputation results are reported where missing is assumed smoking. RESULTS: Retention on was 63% at 6 weeks and 50% at 12 weeks. At 12 weeks, 68% of the NRT group reported using combination NRT while 96% of the NVP group used the device. Acceptability ratings for the products were high in both groups. At 12 weeks, 14% of the NVP group and 18% of the NRT group reported not smoking at all in the last 7 days. Mean CPD among continued smokers decreased significantly between baseline to 12 weeks in both groups; from 19.91 to 4.72 for the NVP group (p < .001) and from 20.88 to 5.52 in the NRT group (p < .001). Cravings and withdrawal symptoms significantly decreased for both groups. CONCLUSIONS: Clients completing residential withdrawal readily engaged with smoking cessation post-treatment when given the opportunity. Further research is required to identify the most effective treatments postwithdrawal for this population at elevated risk of tobacco-related harm. TRIAL REGISTRATION NUMBER: ACTRN12617000849392. IMPLICATIONS: This pilot study showed that smoking cessation support involving options for nicotine replacement and Quitline-delivered cognitive behavioral counseling is attractive to people after they have been discharged from SUD treatment. Both nicotine vaping products and nicotine replacement therapies were highly acceptable and used by participants who reported reductions in cravings for cigarettes and perceptions of withdrawal symptoms and reductions in number of cigarettes smoked. Some participants self-reported abstinence from cigarettes-around one in five reported having quit smoking cigarettes at 12 weeks postdischarge. The results have significant public health implications for providing quit support following discharge from SUD treatment.

Specialist alcohol inpatient treatment admissions and non-specialist hospital admissions for alcohol withdrawal in England: an inverse relationship.

AIMS: We assessed the relationship between specialist and non-specialist admissions for alcohol withdrawal since the introduction of the UK government Health and Social Care Act in 2012. METHODS: Using publicly available national data sets from 2009 to 2019, we compared the number of alcohol withdrawal admissions and estimated costs in specialist and non-specialist treatment settings. RESULTS: A significant negative correlation providing strong evidence of an association was observed between the fall in specialist and rise in non-specialist admissions. Significant cost reductions within specialist services were displaced to non-specialist settings. CONCLUSIONS: The shift in demand from specialist to non-specialist alcohol admissions due to policy changes in England should be reversed by specialist workforce investment to improve outcomes. In the meantime, non-specialist services and staff must be resourced and equipped to meet the complex needs of these service users.

Influence of Pennsylvania liquor store closures during the COVID-19 pandemic on alcohol withdrawal consultations.

INTRODUCTION: Alcohol withdrawal syndrome (AWS) is a serious consequence of alcohol use disorder (AUD). Due to the current COVID-19 pandemic there was a closure of Pennsylvania (PA) liquor stores on March 17, 2020. METHODS: This is a retrospective, observational study of AWS patients presenting to a tertiary care hospital. We used descriptive statistics for continuous and categorical variables and compared AWS consults placed to the medical toxicology service for six months preceding liquor store closure to those placed between March 17, 2020 and August 31, 2020. We compared this to consults placed to the medical toxicology service placed from October 1, 2019 through March 16, 2020. Charts were identified based on consults placed to the medical toxicology service, and alcohol withdrawal was determined via chart review by a medical toxicologist. This study did not require IRB approval. We evaluated Emergency Department (ED) length of stay (LOS), weekly and monthly consultation rate, rate of admission and ED recidivism, both pre- and post-liquor store closure. RESULTS: A total of 324 AWS consults were placed during the ten month period. 142 (43.8%) and 182 (56.2%) consults were pre- and post-liquor store closure. The number of consults was not statistically significant comparing these two time frames. There was no significant difference by patient age, gender, or race or by weekly or monthly consultation rate when comparing pre- and post-liquor store periods. The median ED LOS was 7 h (95% Confidence Interval (CI) Larson et al. (2012), Pollard et al. (2020) [5, 11]) and did not significantly differ between pre- and post-liquor store periods (p = 0.78). 92.9% of AWS patients required admission without significant difference between the pre- and post-liquor store closure periods (94.4% vs. 91.8%, p = 0.36). There was a significant increase in the number of AWS patients requiring a return ED visit (Odds Ratio 2.49; 95% CI [1.38, 4.49]) post closure. CONCLUSION: There were nearly 2.5 times greater odds of ED recidivism among post-liquor store closure AWS patients compared with pre-closure AWS patients.

Care of the Patient Using Cannabis.

The past 2 decades have seen a revolution in legal access to cannabis, driven largely by activists and business interests. As a result, the population of cannabis users nationwide-especially daily users-has grown significantly. An estimated 4.5-7 million persons in the United States now meet criteria for cannabis use disorder annually. This article focuses on the effects of cannabis use, intoxication, and withdrawal while also reviewing the developmental pathways of cannabis use disorder as well as evidence-based pharmacologic and psychosocial treatments.

Alcohol Withdrawal Syndrome in Neurocritical Care Unit: Assessment and Treatment Challenges.

Alcohol withdrawal syndrome (AWS) can range from mild jittery movements, nausea, sweating to more severe symptoms such as seizure and death. Severe AWS can worsen cognitive function, increase hospital length of stay, and in-hospital mortality and morbidity. Due to a lack of reliable history of present illness in many patients with neurological injury as well as similarities in clinical presentation of AWS and some commonly encountered neurological syndromes, the true incidence of AWS in neurocritical care patients remains unknown. This review discusses challenges in the assessment and treatment of AWS in patients with neurological injury, including the utility of different scoring systems such as the Clinical Institute Withdrawal Assessment and the Minnesota Detoxification Scale as well as the reliability of admission alcohol levels in predicting AWS. Treatment strategies such as symptom-based versus fixed dose benzodiazepine therapy and alternative agents such as baclofen, carbamazepine, dexmedetomidine, gabapentin, phenobarbital, ketamine, propofol, and valproic acid are also discussed. Finally, a treatment algorithm considering the neurocritical care patient is proposed to help guide therapy in this setting.

Enriched Environment Ameliorates Cognitive Deficits and Locomotor Sensitization in Morphine-Withdrawn Rats Receiving Methadone Maintenance Treatment.

OBJECTIVE: This study was designed to examine whether enriched environments (EE) would attenuate object recognition and spatial learning and memory deficits and locomotor sensitization induced by methadone maintenance treatment (MMT) in morphine-withdrawn rats. METHODS: Male Wistar rats (170 ± 10 g) were injected with bi-daily doses (10 mg/kg, 12-h intervals) of morphine for 14 days. Rats receiving MMT were reared in the standard environment (SE) or EE during 30 days of morphine withdrawal. Then, the rats were tested for object recognition (the object recognition memory test, ORMT) and spatial learning and memory (the water maze) and then challenged with morphine (1 mg/kg, i.p.) and evaluated for locomotor activity (open-field box). RESULTS: The results revealed that the dependent/saline/EE (D/Sal/EE) and D/methadone/EE (D/Meth/EE) rats exhibited significant preference for the new object (p = 0.006 and p = 0.049), spent more time in the target zone (p = 0.045 and p = 0.005) on the water maze, and displayed a lower level of distance traveled (p = 0.002 and p = 0.0001) compared to their control groups reared in SE. CONCLUSIONS: We conclude that exposure to EE could ameliorate the object recognition and spatial memory deficits and also decrease locomotor sensitivity in morphine-withdrawn rats receiving MMT. Thus, EE may be beneficial in the treatment of addiction during MMT.

Transition of Patients with Opioid Use Disorder from Buprenorphine to Extended-Release Naltrexone: A Randomized Clinical Trial Assessing Two Transition Regimens.

BACKGROUND AND OBJECTIVE: When patients seek to discontinue buprenorphine (BUP) treatment, monthly injectable extended-release naltrexone (XR-NTX) may help them avoid relapse. The efficacy of low ascending doses of oral NTX vs placebo for patients transitioning from BUP to XR-NTX is evaluated in this study. METHODS: In a phase 3, hybrid residential/outpatient study, clinically stable participants with opioid use disorder (N = 101), receiving BUP for more than or equal to 3 months and seeking antagonist treatment, were randomized (1:1) to 7 residential days of descending doses of BUP and low ascending doses of oral NTX (NTX/BUP, n = 50) or placebo (PBO-N/BUP, n = 51). Both groups received standing ancillary medications and psychoeducational counseling. Following negative naloxone challenge, participants received XR-NTX (day 8). The primary endpoint was the proportion of participants who received and tolerated XR-NTX. RESULTS: There was no statistical difference between groups for participants receiving a first dose of XR-NTX: 68.6% (NTX/BUP) vs 76.0% (PBO-N/BUP; P = .407). The mean number of days with peak Clinical Opiate Withdrawal Scale (COWS) score less than or equal to 12 during the treatment period (days 1-7) was similar for NTX/BUP and PBO-N/BUP groups (5.8 vs 6.3; P = .511). Opioid withdrawal symptoms during XR-NTX induction and post-XR-NTX observation period (days 8-11) were mild and similar between groups (mean peak COWS score: NTX/BUP, 5.1 vs PBO-N/BUP, 5.4; P = .464). Adverse events were mostly mild/moderate. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Low ascending doses of oral NTX did not increase induction rates onto XR-NTX compared with placebo. The overall rate of successful induction across treatment groups supports a brief BUP taper with standing ancillary medications as a well-tolerated approach for patients seeking transition from BUP to XR-NTX.

One million screened: Scaling up SBIRT and buprenorphine treatment in hospital emergency departments across Maryland.

PURPOSE: Identification of problematic alcohol use and substance use in the population has been a clinical challenge, especially during the heightened years of the opioid epidemic. Bringing Screening, Brief Intervention, and Referral to Treatment (SBIRT) to scale in medical settings, such as hospital emergency departments (EDs) could facilitate broad identification of substance use disorders, timely delivery of brief interventions, and successful linkages to treatment. PROCEDURES: This large-scale data analysis pulled electronic health record (EHR) data from 23 hospitals in the state of Maryland for over 1 million patient visits between July 2014 and November 2018. FINDINGS: Of the 1,097,142 ED patients screened, 17.2% screened positive for problematic alcohol or any drug use in the previous 12 months. During this same period, 79,899 brief interventions were delivered, 15,961 referrals to outpatient treatment were made and 38.3% of those were successfully linked to treatment. Of the 950 patients exhibiting withdrawal symptoms, over two-thirds patients (70.1%; n = 666) were administered buprenorphine, 94.6% (n = 630) accepted a referral to buprenorphine treatment in the community, and 64.6% (n = 430) attended their first outpatient buprenorphine treatment visit. A total of 2382 patients presented to the ED with a suspected opioid overdose, over half were referred to the intervention program (53.8%) and 63.2% were successfully engaged by the PRCs in the ED. CONCLUSIONS: This analysis supports the scalability of SBIRT in hospital EDs and presents an implementation model that can be replicated in EDs nationwide.
