Sustained Care Smoking Cessation Intervention for Individuals Hospitalized for Psychiatric Disorders: The Helping HAND 3 Randomized Clinical Trial.

Importance: Smoking among individuals with serious mental illness (SMI) represents a major public health problem. Intervening during a psychiatric hospital stay may provide an opportunity to aid engagement in smoking cessation treatment and facilitate success in quitting. Objective: To examine the effectiveness of a multicomponent, sustained care (SusC) smoking cessation intervention in adults with SMI receiving inpatient psychiatric care. Design, Setting, and Participants: The Helping HAND 3 randomized clinical trial compared SusC with usual care (UC) among individuals with SMI who smoked daily and were receiving inpatient psychiatric care in Austin, Texas, in a single hospital. The study was conducted from July 2015 through August 2019. Interventions: The UC intervention involved brief smoking cessation information, self-help materials and advice from the admitting nurse, and an offer to provide nicotine replacement therapy during hospitalization. The SusC intervention included 4 main components designed to facilitate patient engagement with postdischarge smoking cessation resources: (1) inpatient motivational counseling; (2) free transdermal nicotine patches on discharge; (3) an offer of free postdischarge telephone quitline, text-based, and/or web-based smoking cessation counseling, and (4) postdischarge automated interactive voice response calls or text messages. Main Outcomes and Measures: The primary outcome was biochemically verified 7-day point-prevalence abstinence at 6-month follow-up. A secondary outcome was self-reported smoking cessation treatment use at 1, 3, and 6 months after discharge. Results: A total of 353 participants were randomized, of whom 342 were included in analyses (mean [SD] age, 35.8 [12.3] years; 268 White individuals [78.4%]; 280 non-Hispanic individuals [81.9%]; 169 women [49.4%]). They reported smoking a mean (SD) of 16.9 (10.4) cigarettes per day. Participants in the SusC group evidenced significantly higher 6-month follow-up point-prevalence abstinence rates than those in the UC group (8.9% vs 3.5%; adjusted odds ratio, 2.95 [95% CI, 1.24-6.99]; P = .01). The number needed to treat was 18.5 (95% CI, 9.6-306.4). A series of sensitivity analyses confirmed effectiveness. Finally, participants in the SusC group were significantly more likely to report using smoking cessation treatment over the 6 months postdischarge compared with participants in the UC group (74.6% vs 40.5%; relative risk, 1.8 [95% CI, 1.51-2.25]; P < .001). Conclusions and Relevance: The findings of this randomized clinical trial provide evidence for the effectiveness of a scalable, multicomponent intervention in promoting smoking cessation treatment use and smoking abstinence in individuals with SMI following hospital discharge.

Adaptation of a sustained care cessation intervention for smokers hospitalized for psychiatric disorders: Study protocol for a randomized controlled trial.

BACKGROUND: Individuals with serious mental illness (SMI) smoke at disproportionately higher rates than those without SMI, have lifespans 25-32 years shorter, and thus bear an especially large burden of tobacco-related morbidity and mortality. Several recent studies demonstrate that smokers with SMI can successfully quit smoking with adequate support. Further evidence shows that using technology to deliver sustained care interventions to hospitalized smokers can lead to smoking cessation up to 6 months after discharge. The current comparative effectiveness trial adapts a technology-assisted sustained care intervention designed for smokers admitted to a general hospital and tests whether this approach can produce higher cessation rates compared to usual care for smokers admitted to a psychiatric inpatient unit. METHODS: A total of 353 eligible patients hospitalized for psychiatric illness are randomized by cohort into one of two conditions, Sustained Care (SusC) or Usual Care (UC), and are followed for six months after discharge. Participants assigned to UC receive brief tobacco education delivered by a hospital nurse during or soon after admission. Those assigned to SusC receive a 40-min, in-hospital motivational counseling intervention. Upon discharge, they also receive up to 8 weeks of free nicotine patches, automated interactive voice response (IVR) telephone and text messaging, and access to cessation counseling resources lasting 3 months post discharge. Smoking cessation outcomes are measured at 1-, 3- and 6-months post hospital discharge. CONCLUSION: Results from this comparative effectiveness trial will add to our understanding of acceptable and effective smoking cessation approaches for patients hospitalized with SMI.

Impact of Gabapentin Adjunct use with Benzodiazepines for the Treatment of Alcohol Withdrawal in a Psychiatric Hospital.

Introduction: Benzodiazepines are currently the gold standard for treatment of alcohol withdrawal. Gabapentin has growing evidence to support its use in the treatment of alcohol use disorder, however there is limited evidence regarding its role in the treatment of alcohol withdrawal. The purpose of this study was to determine if adjunctive gabapentin reduces the need for benzodiazepine (BZD) administration during alcohol withdrawal. Methods: This was a retrospective single-center cohort study. Patients were included if they were 18-89 years old, had an underlying alcohol use disorder, and were initiated on the Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised (CIWA-Ar) protocol with or without scheduled gabapentin. They were excluded if they had a BZD use disorder, were on concomitant anti-epileptics, as-needed gabapentin, or BZDs outside the CIWA-Ar protocol. Results: A total of 129 patients met inclusion criteria (n = 63 gabapentin group and 66 non-gabapentin group). There was a significant difference in as-needed BZD requirements, with the gabapentin group requiring a higher number of as-needed BZDs in the initial 72 hours of treatment (gabapentin 6 [IQR 0.5-10] non-gabapentin 2 [IQR 0-4]; p = 0.01) and overall (gabapentin 6 [IQR 0.5-10] vs. non-gabapentin 2 [IQR 0-5.5]; p = 0.01). The gabapentin group also had higher maximum CIWA-Ar scores in the initial 72 hours of treatment, and higher anxiety item scores in the initial 48 hours. Conclusion: Gabapentin was not shown to reduce as-needed BZD requirements in patients with a diagnosis of alcohol use disorder admitted for alcohol withdrawal.

Increased Orbitofrontal Brain Activation after Administration of a Selective Adenosine A(2A) Antagonist in Cocaine Dependent Subjects.

BACKGROUND: Positron Emission Tomography imaging studies provide evidence of reduced dopamine function in cocaine dependent subjects in the striatum, which is correlated with prefrontal cortical glucose metabolism, particularly in the orbitofrontal cortex. However, whether enhancement of dopamine in the striatum in cocaine dependent subjects would be associated with changes in prefrontal cortical brain activation is unknown. One novel class of medications that enhance dopamine function via heteromer formation with dopamine receptors in the striatum is the selective adenosine A(2A) receptor antagonists. This study sought to determine the effects administration of the selective adenosine A(2A) receptor antagonist SYN115 on brain function in cocaine dependent subjects. METHODOLOGY/PRINCIPLE FINDINGS: Twelve cocaine dependent subjects underwent two fMRI scans (one after a dose of placebo and one after a dose of 100 mg of SYN115) while performing a working memory task with three levels of difficulty (3, 5, and 7 digits). fMRI results showed that for 7-digit working memory activation there was significantly greater activation from SYN115 compared to placebo in portions of left (L) lateral orbitofrontal cortex, L insula, and L superior and middle temporal pole. CONCLUSION/SIGNIFICANCE: These findings are consistent with enhanced dopamine function in the striatum in cocaine dependent subjects via blockade of adenosine A(2A) receptors producing increased brain activation in the orbitofrontal cortex and other cortical regions. This suggests that at least some of the changes in brain activation in prefrontal cortical regions in cocaine dependent subjects may be related to altered striatal dopamine function, and that enhancement of dopamine function via adenosine A(2A) receptor blockade could be explored further for amelioration of neurobehavioral deficits associated with chronic cocaine use.

Criminal conviction, impulsivity, and course of illness in bipolar disorder.

OBJECTIVE: Criminal behavior in bipolar disorder may be related to substance use disorders, personality disorders, or other comorbidities potentially related to impulsivity. We investigated relationships among impulsivity, antisocial personality disorder (ASPD) or borderline personality disorder symptoms, substance use disorder, course of illness, and history of criminal behavior in bipolar disorder. METHODS: A total of 112 subjects with bipolar disorder were recruited from the community. Diagnosis was by Structured Clinical Interview for DSM-IV (SCID-I and SCID-II); psychiatric symptom assessment by the Change version of the Schedule for Affective Disorders and Schizophrenia (SADS-C); severity of Axis II symptoms by ASPD and borderline personality disorder SCID-II symptoms; and impulsivity by questionnaire and response inhibition measures. RESULTS: A total of 29 subjects self-reported histories of criminal conviction. Compared to other subjects, those with convictions had more ASPD symptoms, less education, more substance use disorder, more suicide attempt history, and a more recurrent course with propensity toward mania. They had increased impulsivity as reflected by impaired response inhibition, but did not differ in questionnaire-measured impulsivity. On logit analysis, impaired response inhibition and ASPD symptoms, but not substance use disorder, were significantly associated with criminal history. Subjects convicted for violent crimes were not more impulsive than those convicted for nonviolent crimes. CONCLUSIONS: In this community sample, a self-reported history of criminal behavior is related to ASPD symptoms, a recurrent and predominately manic course of illness, and impaired response inhibition in bipolar disorder, independent of current clinical state.

Long-acting injectable naltrexone for the management of patients with opioid dependence.

Opioid dependence is a condition with serious clinical ramifications. Treatment has focused on detoxification, agonist therapy with methadone or buprenorphine, or remission maintenance with the opioid antagonist, naltrexone. Treatment with oral naltrexone has been limited by poor treatment adherence and relapse. Studies with long-acting formulations have shown increased treatment adherence. Extended-release injectable naltrexone has been used for the treatment of alcohol dependence, and has recently received an indication for treatment of opioid dependence from the US Food and Drug Administration. Dosing occurs once monthly and existing data with long-acting naltrexone supports efficacy of treatment for opioid dependence; however published data is sparse. Treatment with long-acting naltrexone should be monitored for hepatotoxicity, and patients should be made aware of increased risk of overdose with administration of opioids during and immediately after discontinuation of long-acting naltrexone.

Neuropsychiatry of aggression.

Aggression is a serious medical problem that can place both the patient and the health care provider at risk. Aggression can result from medical, neurologic, and/or psychiatric disorders. A comprehensive patient evaluation is needed. Treatment options include pharmacotherapy as well as nonpharmacologic interventions, both of which need to be individualized to the patient.

Relationship between impulsivity and decision making in cocaine dependence.

Impulsivity and decision making are associated on a theoretical level in that impaired planning is a component of both. However, few studies have examined the relationship between measures of decision making and impulsivity in clinical populations. The purpose of this study was to compare cocaine-dependent subjects to controls on a measure of decision making (the Iowa Gambling Task or IGT), a questionnaire measure of impulsivity (the Barratt Impulsiveness Scale or BIS-11) and a measure of behavioural inhibition (the immediate memory task or IMT), and to examine the interrelationship among these measures. Results of the study showed that cocaine-dependent subjects made more disadvantageous choices on the IGT, had higher scores on the BIS and more commission errors on the IMT. Cognitive model analysis showed that choice consistency factors on the IGT differed between cocaine-dependent subjects and controls. However, there was no significant correlation between IGT performance and the BIS total score or subscales or IMT commission errors. These results suggest that in cocaine-dependent subjects there is little overlap between decision making as measured by the IGT and impulsivity/behavioural inhibition as measured by the BIS and IMT.

Working memory fMRI activation in cocaine-dependent subjects: association with treatment response.

Functional magnetic resonance imaging (fMRI) studies of early abstinence cocaine users offer information about the state of the brain when most cocaine users seek treatment. This study examined the relationship between pretreatment brain function and subsequent treatment response in 19 treatment-seeking early abstinence cocaine-dependent (CD) subjects. These subjects and 14 non-drug-using control subjects underwent fMRI while performing a working memory task with three levels of difficulty. CD subjects were then randomized to treatment studies. Results showed CD subjects had significantly lower (random effects, corrected for multiple comparisons) brain activation in caudate, putamen, cingulate gyrus, middle and superior frontal gyri, inferior frontal gyrus pars triangularis and pars opercularis, precentral gyrus, and thalamus compared with non-drug-using controls. Within CD subjects, thalamic activation significantly correlated with treatment response. This study shows CD subjects in early abstinence have alterations of brain function in frontal, striatal, and thalamic brain regions known to be part of a circuit associated with motor control, reward, and cognition. Subjects with pretreatment thalamic deactivation showed the poorest treatment response, possibly related to thalamic involvement in mesocortical and mesolimbic dopamine projections.

Use of stimulants to treat cocaine and methamphetamine abuse.

The concept of using stimulants to treat cocaine and methamphetamine dependence is largely based on the "replacement" therapy model that has shown efficacy for treating nicotine and opiate dependence. Although results have been mixed, some evidence supports using stimulant medication to reduce cocaine use. There are not enough data to date to determine the efficacy of stimulants for methamphetamine dependence. Drawbacks of stimulants as treatments include the potential for abuse of the treatment, which necessitates careful screening and monitoring of patients. Possible reasons for efficacy of stimulants include enhancement of monoamine function dysregulated by chronic cocaine or methamphetamine use. Newer medications that enhance dopamine function but lack the abuse potential of older stimulants are being studied. It is hoped that these medications will provide safe, effective treatment for cocaine and methamphetamine dependence, but more research on this topic is needed.
