A Stage I Pilot Study of Acceptance and Commitment Therapy for Methadone Detoxification

BACKGROUND While agonist replacement therapies are effective for managing opioid dependence, community treatment programs are increasingly choosing detoxification. Unfortunately, success rates for opioid detoxification are very low, in part, due to physical and psychological symptoms associated with opioid withdrawal. Few behavior therapies specifically address the distressing experiences specific to opioid withdrawal. A novel behavioral treatment, acceptance and commitment therapy (ACT), works from the premise that the avoidance of unpleasant private experiences (thoughts, feelings, bodily sensations) is ubiquitous yet may be pathogenic, resulting in treatment drop-out and further drug use. METHODS This Stage I pilot study developed and tested an ACT-based opioid detoxification behavioral therapy. Opioid dependent patients (N=56) who were attending a licensed methadone clinic were randomized to receive either 24 individual therapy sessions of ACT or drug counseling (DC) in the context of a 6-month methadone dose reduction program. RESULTS While no difference was found on opioid use during treatment, 37% of participants in the ACT condition were successfully detoxified at the end of treatment compared to 19% of those who received DC. Fear of detoxification was also reduced across time in the ACT condition relative to DC. CONCLUSION This first study of ACT to assist opioid detoxification indicates promise. Research is needed to refine specific treatment strategies for this population to further strengthen effects.

Initiation and Persistence of Alcohol Use in United States Black, Hispanic, and White Male and Female Youth

BACKGROUND The relation between early and frequent alcohol use and later difficulties is quite strong. However, the degree that alcohol use persists, which is often a necessary cause for developing alcohol-related problems or an alcohol use disorder, is not well studied, particularly with attention to race and gender. A novel statistical approach, the Multi-facet Longitudinal Model, enables the concurrent study of age of initiation and persistence. METHODS The models were applied to longitudinal data on youth alcohol use from ages 12 through 19, collected in the (U.S.) National Longitudinal Survey of Youth 1997 cohort (N=8984). RESULTS Results confirmed that Black adolescents initiate alcohol use at later ages than do White youth. Further, after initiation, White adolescents were substantially more likely than Black adolescents to continue reporting alcohol use in subsequent years. Hispanic teens showed an intermediate pattern. Gender differences were more ambiguous, with a tendency for boys to be less likely to continue drinking after initiation than were girls. CONCLUSIONS Novel findings from the new analytic models suggest differential implications of early alcohol use by race and gender. Early use of alcohol might be less consequential for males who initiate alcohol use early, Black, and Hispanic youth than for their female and White counterparts.

A qualitative assessment of the perceived risks of electronic cigarette and hookah use in pregnancy

BackgroundStudies reveal that electronic cigarette (e-cigarette) and hookah use are increasing among adolescents and young adults. However, the long-term health effects are unknown, especially with regards to pregnancy. Because of the increased use in women of reproductive age, and the unknown long-term health risks, our primary objectives were to determine the perceived risks of e-cigarette and hookah use in pregnancy, and learn common colloquial terms associated with e-cigarettes. Furthermore, we sought to determine if there is a stigma associated with e-cigarette use in pregnancy.MethodsEleven focus groups including 87 participants were conducted immediately following regularly scheduled CenteringPregnancy® prenatal care with women at three different clinics in the greater Houston area. A minimum of two facilitators led the groups, using ten lead-in prompts, with Spanish translation as necessary. Facilitators took notes which were compared immediately following each group discussion and each group was audio recorded and transcribed. Three facilitators utilized NVivo 9.0 software to organize the transcribed data into nodes to identify major themes. To increase rigor, transcripts were further analyzed by two obstetricians who were instructed to find the major themes.ResultsAnalyses revealed contradicting themes concerning e-cigarette use. In general, e-cigarettes were perceived as safer alternatives to regular tobacco cigarettes, especially if used as smoking cessation devices. A major theme is that use in pregnancy is harmful to the fetus. However, it was perceived that use for smoking cessation in pregnancy may have fewer side effects. We found that a common term for e-cigarettes is “Blu.” In our discussion of hookah use, participants perceived use as popular among teenagers and that use in pregnancy is dangerous for the fetus.ConclusionsAlthough a strong theme emerged against hookah use, we found contradicting themes in our discussions on e-cigarette use in pregnancy. It is possible that e-cigarette use will not carry the same stigma as regular cigarette smoking in pregnancy. In addition, the impression of e-cigarettes as a healthier alternative to smoking may influence use in pregnancy. Clinicians need to be prepared for questions of e-cigarette safety and efficacy as smoking cessation devices from their pregnant patients who smoke, and women who smoke and are planning to become pregnant.

Feasibility and efficacy of an intervention to reduce secondhand smoke exposure among infants discharged from a neonatal intensive care unit

Objective:To examine the feasibility and efficacy of a hospital-based, motivational intervention to reduce secondhand smoke exposure (SHSe) with mothers of infants in a neonatal intensive care unit (NICU).Study Design:One-hundred and forty-four mothers with infants (⩽1500 g at birth or ⩾12 h ventilation) in a NICU who reported a smoker in the household were randomized to two sessions of motivational interviewing (MI) conducted in the hospital, usual care (UC) or usual care-reduced measurement (UC-RM); follow-up occurred at 1- and 6-months post discharge.Result:For households that did not have a total smoking ban at baseline, 63.6% of those in the MI group instituted a ban by 1-month post discharge compared with 20% of the UC group, P<0.02. Six months post discharge, fewer smoking bans were noted in the UC-RM group relative to MI and UC, P<0.01.Conclusion:A need for SHSe interventions among NICU parents exists and initial evidence suggests MI can impact SHSe after discharge.

Thirdhand smoke contamination in hospital settings: assessing exposure risk for vulnerable paediatric patients

Background Tobacco has regained the status of the worlds number two killer behind heart/vascular disease. Thirdhand smoke (THS) residue and particles from secondhand smoke (SHS) are suspected health hazards (eg, DNA damage) that are likely to contribute to morbidity and mortality, especially in vulnerable children. THS is easily transported and deposited indoors, where it persists and exposes individuals for months, creating potential health consequences in seemingly nicotine-free environments, particularly for vulnerable patients. We collected THS data to estimate infant exposure in the neonatal ICU (NICU) after visits from household smokers. Infant exposure to nicotine, potentially from THS, was assessed via assays of infant urine. Methods Participants were mothers who smoked and had an infant in the NICU (N=5). Participants provided surface nicotine samples from their fingers, infants’ crib/incubator and hospital-provided furniture. Infant urine was analysed for cotinine, cotinines major metabolite: trans-3′-hydroxycotinine (3HC) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), a metabolite of the nicotine-derived and tobacco-specific carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). Results Incubators/cribs and other furniture had detectable surface nicotine. Detectable levels of cotinine, 3HC and NNAL were found in the infants’ urine. Discussion THS appears to be ubiquitous, even in closely guarded healthcare settings. Future research will address potential health consequences and THS-reduction policies. Ultimately, hospital policies and interventions to reduce THS transport and exposure may prove necessary, especially for immunocompromised children.

Secondhand smoke risk in infants discharged from an NICU: potential for significant health disparities?

INTRODUCTION Secondhand smoke exposure (SHSe) threatens fragile infants discharged from a neonatal intensive care unit (NICU). Smoking practices were examined in families with a high respiratory risk infant (born at very low birth weight; ventilated > 12 hr) in a Houston, Texas, NICU. Socioeconomic status, race, and mental health status were hypothesized to be related to SHSe and household smoking bans. METHODS Data were collected as part of The Babys Breath Project, a hospital-based SHSe intervention trial targeting parents with a high-risk infant in the NICU who reported a smoker in the household (N = 99). Measures of sociodemographics, smoking, home and car smoking bans, and depression were collected. RESULTS Overall, 26% of all families with a high-risk infant in the NICU reported a household smoker. Almost half of the families with a smoker reported an annual income of less than

Opioid withdrawal, craving, and use during and after outpatient buprenorphine stabilization and taper: A discrete survival and growth mixture model

25,000 reported having a total smoking ban in place relative to almost 60% of families earning more (p < .01). African American and Caucasian families were less likely to have a smoking ban compared with Hispanics (p < .05). Mothers who reported no smoking ban were more depressed than those who had a household smoking ban (p < .02). CONCLUSIONS The most disadvantaged families were least likely to have protective health behaviors in place to reduce SHSe and, consequently, are most at-risk for tobacco exposure and subsequent tobacco-related health disparities. Innovative SHSe interventions for this vulnerable population are sorely needed.

Baby’s Breath II protocol development and design: A secondhand smoke exposure prevention program targeting infants discharged from a neonatal intensive care unit

Purpose:This study investigated potential associations between maternal depression and specific infant health conditions, smoking, and socioeconomic characteristics among mothers of high-risk infants during medical follow-up visits. Study Design and Methods:Cross-sectional self-report, and interview data were collected from 114 mothers of high-risk infants previously discharged from a neonatal intensive care unit. Mothers were assessed at a postdischarge clinic visit. Results:Prevalence rates for a Center for Epidemiological Studies-Depression Scale score ≥16) suggestive of a depressive disorder exceeded 20% at all time points for this sample of predominantly low-income, minority-race mothers. A greater number of mothers who had infants with a highly visible illness (e.g., surgical necrotizing enterocolitis) were depressed. Depression was also associated with the presence of a household smoker, younger age, and less education and income. Clinical Implications:Given the prevalence rates, routine screening for postpartum depression in mothers of high-risk infants is imperative, with particular attention to the infants health, smoking, and socioeconomic variables.

Thirdhand smoke: State of the science and a call for policy expansion

INTRODUCTION Most patients relapse to opioids within one month of opioid agonist detoxification, making the antecedents and parallel processes of first use critical for investigation. Craving and withdrawal are often studied in relationship to opioid outcomes, and a novel analytic strategy applied to these two phenomena may indicate targeted intervention strategies. METHODS Specifically, this secondary data analysis of the Prescription Opioid Addiction Treatment Study used a discrete-time mixture analysis with time-to-first opioid use (survival) simultaneously predicted by craving and withdrawal growth trajectories. This analysis characterized heterogeneity among prescription opioid-dependent individuals (N=653) into latent classes (i.e., latent class analysis [LCA]) during and after buprenorphine/naloxone stabilization and taper. RESULTS A 4-latent class solution was selected for overall model fit and clinical parsimony. In order of shortest to longest time-to-first use, the 4 classes were characterized as 1) high craving and withdrawal, 2) intermediate craving and withdrawal, 3) high initial craving with low craving and withdrawal trajectories and 4) a low initial craving with low craving and withdrawal trajectories. Odds ratio calculations showed statistically significant differences in time-to-first use across classes. CONCLUSIONS Generally, participants with lower baseline levels and greater decreases in craving and withdrawal during stabilization combined with slower craving and withdrawal rebound during buprenorphine taper remained opioid-free longer. This exploratory work expanded on the importance of monitoring craving and withdrawal during buprenorphine induction, stabilization, and taper. Future research may allow individually tailored and timely interventions to be developed to extend time-to-first opioid use.
