Routine care interventions with the parents of adult drug and alcohol users

Introduction and aims: To explore routine care interventions which enable parents to support the therapeutic effort of their adult child in drug and alcohol treatment.

Design and methods: Inductive content analysis was used to analyze the experiences of 31 Greek addiction professionals who participated in focus groups.

Findings: Professionals adopted various interventions which included (a) respond to parents quest for help, (b) involvement of the distant parent in treatment, (c) boundary setting, (d) facilitation of parent-child communication, and (e) support of parental changes. These interventions were perceived as necessary, both for motivating and sustaining the client’s change, and for alleviating the parents’ chronic grief and distress over their child’s addiction.

Conclusion: Overall, addiction professionals perceived low intensity interventions, information giving, and non- judgmental informal interactions as catalysts for the parents involvement in addiction treatment.     

Craving-induced effects of different drug cues on persons abstaining from heroin

Background: The key factors of inducing drug cravings in persons abstaining from drug use remain a focus of addictions research. Given the accumulating evidences, the scope of cues investigated in the cue-reactivity paradigm has increased considerably. Yet, few studies have examined the effects of the intensity and endurance of different types of cues on their ability to induce craving. This study investigated differences among drug-cue words, negative physiological-cue words, and negative social-cue words in the induction of drug cravings among persons abstaining from heroin.

Methods: The sample consisted of 149 male abstinent heroin abusers from four addiction rehabilitation centers in China. Based on their abstinence lengths, they were labeled as short-term, medium-term, and long-term abstainer participants respectively. All participants completed a stress-imagery task and rated craving by visual analog scale.

Results: There was a significant interaction of cue type and abstinence length. There was no difference on the craving induced by three types of cue words in the short-term group. In the medium-term group, craving induced by negative social-cue words was significantly stronger than that by negative physiological-cue words, but not that by drug-cue words. In the long-term group, the craving induced by negative social-cue words remained the strongest, significantly stronger than that by both drug-cue words and negative physiological-cue words.

Conclusion: Negative social-cue words presented in the current study retain the ability to induce craving in heroin abstainers; this finding suggests that negative social cues encountered under more general circumstances could be a risk factor for relapse.     

Suicidal ideation and attempts among patients with lifetime physical and/or sexual abuse in treatment for substance use disorders

Background: Several studies indicate that lifetime abuse is a relevant risk factor for suicidal ideation and/or attempts. However, little is known about this phenomenon in patients seeking treatment for substance use disorder. The prevalence rate of suicidal ideation and/or suicide attempts was explored among lifetime physically and/or sexually abused patients receiving treatment for drug addiction. The differential characteristics between these patients and those without suicidal behaviours were studied.

Method: Three hundred and seventy-five patients were assessed. Socio-demographic characteristics, addiction severity, lifetime abuse, suicidal ideation and attempts, and psychopathological symptoms were explored.

Results: Eighty-two patients (21.9%) presented with a history of lifetime abuse and were included in the study (37 men and 45 women). Sixty-two per cent of them presented with lifetime suicidal ideation (12.2% in the last month), and 30.5% with suicide attempts (1.2% in the last month). Patients with suicidal ideation or attempts showed a more severe addiction profile (assessed by the EuropASI) and more psychopathological symptoms (assessed by the SCL-90-R).

Conclusion: This study highlights the relationship between previous traumatic experiences and suicidal behaviours. According to these results, systematic screening of suicidal risk in patients seeking treatment in addiction centres with histories of abuse is recommended.     

Development Of A Smartphone Overuse Classification Scale

Background: Smartphone overuse has become prevalent worldwide. The aim of this study is to develop a self-administered scale, the Smartphone Overuse Classification Scale (SOCS) that can be used to screen for different types of smartphone overuse.

Methods: The SOCS consists of three subscales: social network app overuse (S-scale), recreational app overuse (R-scale), and information overload (I-scale). A total of 849 participants were recruited to complete questionnaires, including the SOCS, Young’s Diagnosis Questionnaire (Young’s DQ) and a demographic data form.

Results: Three factors (cognitive disorder, behavioral disorder, and mood disorder) were extracted from each subscale of the SOCS, and these explained over 60% of the variance of each subscale. The Cronbach’s alpha was 0.849 for the SOCS and 0.813, 0.726, and 0.706 for the S-scale, R-scale and I-scale, respectively. Intra-class correlations for the SOCS and its subscales ranged from 0.768 to 0.879. The SOCS and its subscales were moderately or highly correlated with Young’s DQ.

Conclusions: The SOCS may provide a basis for developing specific intervention schemes for different types of smartphone overuse.     

An evaluation of peripapillar choroidal thickness in patients receiving systemic isotretinoin treatment

Purpose: Oral isotretinoin (13-cis retinoic acid, 13-cis RA) was approved for severe acne treatment by the FDA in 1982. The ocular side effects associated with oral isotretinoin use are mostly dose-dependent. Numerous ocular pathologies affect peripapillary choroidal layer primarily or indirectly.

Objective: Evaluation of the peripapillary choroidal layer in the patients receiving oral isotretinoin therapy may aid in explaining the pathophysiology of ocular side effects.

Methods: In this study, peripapillary choroidal thickness was assessed in the patients receiving oral isotretinoin treatment via optical coherent tomography technique.

Results: Significant difference was found in the superotemporal and temporal areas.

Conclusion: Oral isotretinoin treatment may affect the thickness of the peripapillary choroidal layer.     

Lives of Substance: a mixed-method evaluation of a public information website on addiction experiences

Aims: The Lives of Substance (LoS) website presents personal experiences of drug use and ‘addiction’ in people’s own words as part of a larger project of complicating public discourses of addiction, countering stigmatising misconceptions and acting as an intervention in the social production of addiction. This article presents the findings of a mixed-method evaluation of the website, and comments on some of the methodological and practical challenges of evaluating health-related online information resources.

Method: Three data sources were used to examine such as the reach of the website (website analytics); experiences of the website audience (responses to an evaluation survey on the website); and other indicators of use and impact (including social media referrals and organisational links).

Results: In the 10-week evaluation period, 3970 unique users visited the website. Comments provided via the online survey endorsed the website as a means of challenging stereotypes and as presenting drug use as only a ‘part of a person’s whole life’. Twenty-four organisations had linked to the website and 987 social media referrals were recorded.

Conclusion: These data indicate that the LoS website is having some success as a resource for countering addiction-related stigma and offering more holistic and inclusive social understandings of addiction.     

Confidentiality and cultural competence? The realities of engaging young British Pakistanis and Bangladeshis into substance use services

Aims: This paper focuses on the reasons for the under-representation of British South Asians in substance use services. Based on a small-scale evaluation of a substance use service that delivers targeted outreach support within two predominantly Pakistani and Bangladeshi communities in the north west of England, this paper contributes to the debate around how substance use services can best engage with young British Pakistani and Bangladeshi substance users.

Methods: Semi-structured interviews (with six staff members, 18 young Pakistani and Bangladeshi service users, and 18 stakeholders and partner agencies), a detailed ethnographic observation of the service, and an analysis of routinely collected quantitative monitoring data.

Findings: The paper highlights the importance of what Fountain terms low threshold/open access services. Alongside this, the paper argues that the building of trust and confidence in a substance use service is a key when it comes to engaging with young Pakistani and Bangladeshi substance users. Yet this necessary process takes time: something that is at odds with the current trend towards short-term funding regimes and ‘quick wins’.

Conclusions: The paper concludes by advocating the need for, not only a diverse range of engagement strategies, but also a longer term approach when it comes to developing and delivering substance use services aimed at successfully engaging with this particular group of substance users.     

Use of substances among professionals and students of professional programs: a review of the literature

Background and aims: This literature review investigates the scope of information regarding self-reported substance use by professionals and students in professional programs, with a focus on anticipated and actual effects of substances.

Methods: A review of English, peer-reviewed journals and professional journals was conducted. Articles were included if they reported empirical findings of original research and specifically described an aspect of substance use (e.g. type of substance used, patterns of use, reasons for use) by professionals or students.

Results: Of the 130 articles ultimately included, 105 involved anonymous self-administered survey methodology. Self-reported data about the effects of substance use or reasons for use were reported in 35 articles. Reasons for use included positive impact on performance and experience, such as fun, pleasure, sleep, enhanced work performance, improved attention and concentration, and relaxation. Predictive associations were analysed regarding demographic factors, mental health, type of profession, and area of specialisation.

Conclusions: Little is known about the effects of substance use on the performance or experience of professionals or students in professional programs. Research is required that incorporates qualitative methodologies, elicits anticipated and actual effects of substance use, including controlled and beneficial patterns of use. Minimisation of research bias is key to future study of the effects of substance use by professionals or students in professional programs.     

Potential strategies to combat the opioid crisis

Introduction: In the last few decades, the consumption of opioid analgesics in many countries, particularly the US, has dramatically increased. This rise has been paralleled by a proportional number of opioid-related deaths.

Areas covered: The development of opioid guidelines was a response to this health crisis with the intention of reducing the risk of harm related to opioid prescribing. These guidelines have received varying responses ranging from support to criticism. Pain physicians may often provide multidimensional management as the paradigm for responsible opioid treatment. Interventions should focus on preventing new cases of opioid addiction, identifying early cases of opioid addiction, and ensuring access to effective addiction treatment.

Expert opinion: Many activities have been suggested to face the opioid epidemic. Reducing supply is one of the most relevant aspects. Clinicians should find a fine balance that meets the patient’s need for pain relief while minimizing the chance for abuse.     

Optimisation of the microencapsulation of lavender oil by spray drying

Background: Lavender oil consists of around 100 components and is susceptible to volatilisation and degradation reactions.

Aim: Microencapsulate lavender oil by spray drying using a biocompatible polymeric blend of gum acacia and maltodextrin to protect the oil components. Effect of total polymer content, oil loading, gum acacia, and maltodextrin proportions on the size, yield, loading, and encapsulation efficiency of the microparticles was investigated.

Methods: Morphology and oil localisation within microparticles were assessed by confocal laser scanning electron microscope. Structural preservation and compatibility were assessed using Fourier transform infra-red spectroscopy, differential scanning calorimetry, and gas chromatography–mass spectrometry.

Results: Lavender microparticles of size 12.42?±?1.79?µm prepared at 30 w/w% polymer concentration, 16.67 w/w% oil loading, and 25w/w% gum acacia showed maximum oil protection at high loading (12?mg w/w%), and encapsulation efficiency (77.89 w/w%).

Conclusion: Lavender oil was successfully microencapsulated into stable microparticles by spray drying using gum acacia/maltodextrin polymeric blend.     

A 30-year follow-up of substance misusers in Sweden – differences in predictors of mortality between women and men

Background: Differing results on gender specific factors related to mortality risks among substance misusers highlights the need for further research. The present article is based on a 30-year follow-up study on substance misusers treated in residential care for drug problems in Sweden in 1982-1983 aiming to identify and compare gender differences in predictors of mortality.

Method: Original data consists of personal interviews with 1163 substance misusers treated in inpatient units in Sweden during 1982-1983. The outcome variable is death retrieved from the National Cause of Death Register held by the National Board of Health and Welfare. Gender differences and similarities regarding predictors of mortality was estimated in univariate and multivariate models, using Cox proportional hazards models.

Results: School failure, imprisonment and being a parent without custody of the child seem to constitute risk factors for mortality among women, but not among men. A social network of friends seemed to be more important for men. Treatment-dropout was a significant risk factor for premature death among men, but not among women. Both gender reporting alcohol as their self-reported most dominant substance misuse showed higher mortality risks compared with those with stimulants as dominant substance misuse.

Conclusions: Imprisonment was highly predictive of mortality for the women, suggesting that this group is important to pay particular attention to. Suggested differences in the importance of social factors need to be investigated more thoroughly. The substantial hazard revealed for women with polydrug misuse including alcohol calls for attention to this in treatment for substance misuse.     

Secondary cannabis use among London drug treatment service clients

Background: Cannabis is the second most commonly used substance after alcohol among people seeking treatment for other drug use, but no statistics are available regarding secondary cannabis use among drug treatment clients.

Objectives: To investigate levels of secondary cannabis use among drug treatment clients and perceived need for support addressing this use among clients and staff.

Methods: Cross-sectional surveys of clients (N?=?295) and staff (N?=?33) were conducted in 2015 at four London drug and alcohol treatment services. Client measures included recent drug use, type of cannabis used, Severity of Dependence Scale for cannabis, and views on secondary cannabis use treatment. Staff measures included definition of problem cannabis use, importance and timing for addressing secondary cannabis use.

Results: Among clients, 39.7% reported recent secondary cannabis use, with 30.8% of these clients meeting criteria for problem use. Problem users were more likely to be interested in receiving treatment for cannabis use than non-problem users (51.4% versus 10.8%, p?<?.001). Nearly half of staff (48.5%) thought secondary cannabis use should be addressed early in treatment.

Conclusions: Two out of five drug treatment clients used cannabis and a third experienced cannabis-related problems. Many are willing to address cannabis use, but defined treatment pathways are needed.     

Efficacy of istradefylline for gait disorders with freezing of gait in Parkinson’s disease: A single-arm,open-label,prospective, multicenter study

Background: Gait disorders are common in Parkinson’s disease patients who respond poorly to dopaminergic treatment. Blockade of adenosine A_2A receptors is expected to improve gait disorders. Istradefylline is a first-in-class selective adenosine A_2A receptor antagonist with benefits for motor complications associated with Parkinson’s disease.

Research design and methods: This multicenter, open-label, single-group, prospective interventional study evaluated changes in total gait-related scores of the Part II/III Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) and Freezing of Gait Questionnaire (FOG-Q) in 31 Parkinson’s disease patients treated with istradefylline. Gait analysis by portable gait rhythmogram was performed.

Results: MDS-UPDRS Part III gait-related total scores significantly decreased at Weeks 4–12 from baseline with significant improvements in gait, freezing of gait, and postural stability. Significant decreases in MDS-UPDRS Part II total scores and individual item scores at Week 12 indicated improved daily living activities. At Week 12, there were significant improvements in FOG-Q, new FOG-Q, and overall movement per 48 h measured by portable gait rhythmogram. Adverse events occurred in 7/31 patients.

Conclusions: Istradefylline improved gait disorders in Parkinson’s disease patients complicated with freezing of gait, improving their quality of life. No unexpected adverse drug reactions were identified.

Trial registration: UMIN-CTR (UMIN000020288).     

Gender,subclinical organ damage and cardiovascular risk stratification in hypertensive patients

Background: The aims of the study were to assess subclinical organ damage in men and women with hypertension and its subsequent effect on cardiovascular risk, and use of new statistical methods for more precise estimation of cardiovascular risk using vascular cardiovascular risk factors: ankle–brachial index (ABI), intima–media thickness (IMT) and pulse wave velocity (PWV).

Methods: We studied 200 patients: 100 hypertensive and 100 normotensive. The parameters we evaluated included: patient age, ABI, IMT, PWV, serum uric acid and serum C-reactive protein (CRP). In addition, the cardiovascular risk according to the SCORE and Framingham scales was assessed.

Results: In the hypertensive group, there were significant correlations between ABI and the Framingham scale in both sexes. In hypertensive women, there were also significant correlations between IMT and the SCORE scale risk, and IMT and the Framingham scale risk.

In normotensive women, there were significant correlations between ABI and the SCORE scale risk, and between ABI and the Framingham scale risk. In normotensive men, there were significant correlations between PWV and the SCORE scale risk, and between PWV and the Framingham scale risk. Lastly, in the group of normotensive men, there were significant correlations between IMT and the SCORE scale risk, and IMT and the Framingham scale risk.

The possibility of correctly classifying a patient into the high-risk category by a logistic regression model using synchronous ABI, IMT and PWV was high – 74% for the risk according to the SCORE scale (66% in men, 88% in women), and 98% for the Framingham scale.

Conclusions: The addition of recognized subclinical target organ damage tests to the estimation of cardiovascular risk can significantly strengthen the prevention of cardiovascular disease.

Cardiovascular risk estimation follow-up with ABI, PWV and IMT increased the probability of correctly classifying people, especially women, into an at least high-risk category according to the SCORE scale, which has valuable therapeutic implications.     

The burden experienced by Brazilian family members affected by their relatives’ alcohol or drug misuse

Purpose: There is a virtual absence of previous research about the experiences of people affected by the presence of a substance misuser in the family in Brazil.

Materials and methods: A diverse sample of 3158 (80.6% female) affected family members (AFMs) was recruited in the largest cities in all five Brazilian regions. A Brazilian Portuguese translation of a set of standard measures for the assessment of AFM stress, strain, coping, hopefulness and total family burden, based on the stress–strain–coping–support (SSCS) model, was employed.

Results: Mothers and wives reported the greatest burden. Burden was also related to a number of other demographic and background variables, notably being higher for AFMs of lower socio-economic status and for those whose substance misusing relatives were currently receiving hospital treatment. Results offer some support for additive and moderation coping hypotheses, suggesting that greater engaged and tolerant-inactive coping add to stressful impact in the prediction of symptoms, and that lower engaged and tolerant-inactive coping in the face of relatively high stressful impact may be particularly useful in reducing symptom levels.

Conclusions: This is the first national sample of AFMs to be studied in Brazil and the largest to have been reported from any country. The results should help build an emerging picture of how AFMs are affected and assist in planning services for AFMs.     

Evidence of bioequivalence and positive patient user handling of a tocilizumab autoinjector

Background: The anti–interleukin-6 receptor antibody tocilizumab is approved for subcutaneous injection using a prefilled syringe (PFS). We report results from a bioequivalence study in healthy subjects and a user-handling study in patients with rheumatoid arthritis (RA) using an autoinjector (AI) for tocilizumab.

Methods: A randomized crossover study in healthy subjects (N = 161) examined the bioequivalence, safety, and tolerability of tocilizumab after a single subcutaneous injection by AI versus PFS. A nonrandomized observational, real-life human factors study in RA patients (N = 54) assessed user (RA patients, caregivers, health care providers) ability to administer tocilizumab effectively by AI.

Results: Bioequivalence criteria for tocilizumab AI versus PFS were met for key pharmacokinetic parameters. Safety was comparable between devices and consistent with the established tocilizumab profile. In the real-life human factors study, the proportion of users who successfully performed all essential tasks required to operate the AI to deliver the full dose was 92.3% at first assessment and 98.1% at second assessment, with no safety concerns.

Conclusions: Tocilizumab administration by AI was bioequivalent to administration by PFS. Intended users were successful in performing the tasks required to administer tocilizumab by AI. No new safety signals were observed in either study.

Can scare tactics and fear-based messages help deter substance misuse: a systematic review of recent (2005–2017) research

Introduction: Historically, substance use prevention relied heavily on scare tactics and fear-based messages. However, these messages were discouraged from use due to research finding them ineffective or harmful. This review sought to determine if recent research continues to support this finding.

Methods: We conducted a literature review of relevant peer-reviewed studies from 2005 to 2017, categorising results as showing clear evidence of effectiveness, mixed evidence of effectiveness or no evidence of effectiveness. Research on historical scare tactics and fear-based messages was reviewed as a baseline and research on related theoretical models was reviewed for context.

Results: We identified 17 studies that met our inclusion criteria: 10 targeting tobacco use, five targeting alcohol use, one targeting marijuana use and one targeting methamphetamine use. Eight (8) studies found that these messages were more effective at influencing substance use-related measures than positive emotion prevention messages or control messages. Five (5) studies found mixed evidence, and four (4) studies found no evidence of effectiveness.

Discussion: Though not conclusive, our results suggest that these messages may be more effective than previously shown. However, many of the studied messages differed in tone and content from similar, historical messages. Organizations interested in implementing these messages should note these differences.
