Prevalence of anxiety disorders and its co-occurrence with substance use disorder: a clinical study

Background

Epidemiological studies are necessary to develop diagnostic standards for mental disorders. Therefore, this study investigated the prevalence of anxiety disorders, and its correlation with different substances used by patients diagnosed with substance use disorder referred to the Iran Psychiatric Hospital located in Tehran, Iran. Two hundred ninety-two male patients aged 18–65 (Meanage = 36.11, SD = 10.55) were recruited according to the available participant pool. Structured Clinical Interview for DSM-V Axis I Disorders was used to investigate their simultaneous anxiety disorders, and then the correlations with the different substances used during the past year before our study were considered. Based on clinical evaluation and structured psychiatric interviews, we investigated panic disorder, agoraphobia, social anxiety disorder, and generalized anxiety disorder.

Results

Results revealed that generalized anxiety disorder was the most common type of anxiety disorder among subjects of the current study. Further investigations revealed that panic disorder was significantly correlated with the abuse of cannabis (r = 0.116, p value = 0.047), tramadol (r = 0.205, p value < 0.001), and LSD (r = 0.197, p value = 0.001). Moreover, social anxiety disorder was correlated with cannabis (r = 0.124, p value = 0.035), opium (r = 0.186, p value = 0.001), methadone (r = 0.152, p value = 0.010), tramadol (r = 0.258, p value < 0.001), alcohol (r = 0.133, p value = 0.023), LSD (r = 0.123, p value = 0.036), and benzodiazepines (r = 0.168, p value = 0.004). The results indicated that none of the substances was correlated with generalized anxiety disorder as well as agoraphobia. However, agoraphobia had correlations with the intravenous injection as the main route of administration (r = 0.174, p value = 0.004).

Conclusions

Here this study supports the notion that co-occurrence of psychiatric disorders is relatively common and must be taken into consideration when assessing a patient and following up the treatment.

A life-course theory exploration of opioid-related maternal mortality in the United States

BACKGROUND AND AIMS

Between 2007 and 2016, pregnancy-associated mortality resulting from overdose more than doubled in the United States. This study explored the circumstances surrounding maternal opioid-related morbidity and mortality, using the life-course theory as a sensitizing framework to examine how each participant's life-course contributed to her substance use, relapse, recovery or overdose.

DESIGN

A mixed-methods study using semi-structured, in-depth face-to-face interviews and focus groups were conducted.

SETTING

Texas, United States.

PARTICIPANTS

Women who had relapsed into opioid use or experienced a 'near-miss' overdose and family members of women who had died during the maternal period due to opioid overdose were interviewed (n = 99).

MEASUREMENTS

A socio-demographic questionnaire captured participants' ethnicity, age, marital status, medical and mental health history and employment status. The Stressful Life Events Screening Questionnaire-revised (SLESQ-R) assessed life-time exposure to trauma.

FINDINGS

Women reported histories of abuse and loss of a loved one through homicide or suicide. Participants indicated that limited social support, interpersonal conflict with their partner and unaddressed mental illness made recovery more challenging. Additionally, losing their children through the child welfare system was described as punitive and placed them at greater risk for relapse and overdose.

CONCLUSIONS

A life-course theory approach to examining maternal opioid-related morbidity and mortality in Texas, United States reveals the complex needs of women at risk for opioid use relapse and overdose and the significant role of previous traumatic experiences.

Prevalence and Predictors of Symptoms of Depression Among Individuals Seeking Treatment from Australian Drug and Alcohol Outpatient Clinics

This study examined the prevalence of and sociodemographic characteristics associated with elevated symptoms of depression among clients seeking alcohol or other drug (AOD) treatment. Consenting clients attending two AOD outpatient clinics answered demographics, treatment questions and the Patient Health Questionnaire to assess depressive symptoms. Counts and percentages were calculated to determine the prevalence of elevated depressive symptoms. Logistic regression was used to model the odds of having elevated depressive symptoms for client demographics. Of the 203 clients who completed the survey (87% consent rate), 55% (n = 111) demonstrated elevated depressive symptoms. Females were twice as likely to experience elevated symptoms of depression compared to males (OR 2.07; 95% CI 1.05, 4.08; P = 0.037). The high rates of elevated depressive symptoms among individuals seeking AOD treatment highlight the importance of ongoing research to provide effective treatments for this comorbidity. Routine screening and clear treatment pathways may assist with providing high quality care.

Characterizing Anxiety Among Individuals Receiving Treatment for Alcohol and Substance Use Disorders

BACKGROUND

Despite high prevalence of generalized anxiety disorder (GAD) substance use disorder (SUD) comorbidity, little is known regarding demographic characteristics associated with GAD in SUD treatment seekers.

OBJECTIVE

To characterize demographic differences between inpatient SUD treatment seekers reporting varying levels of GAD symptomatology.

DESIGN

General linear models, chi-square test, t test, and correlational analyses were utilized to assess group differences. Groups included those with no history of significant anxiety (No GAD; n = 256), subclinical anxiety (Subclinical; n = 85), and those meeting GAD diagnostic criteria (GAD; n = 61).

RESULTS

The No GAD group differed substantially from Subclinical and GAD individuals. With the exception of polysubstance use, no differences were found regarding Subclinical and GAD groups.

CONCLUSION

Individuals with subclinical GAD symptoms and those meeting diagnostic criteria were nearly identical regarding precursors to problematic substance use, severity of use, and key mental health indicators. Findings suggest subclinical levels of GAD should not be overlooked when assessing and treating SUDs.

The Mothering Experiences of Women With Substance Use Disorders

The aim of this qualitative study was to describe the mothering experiences of women with substance use disorders. We conducted semistructured, individual interviews with 15 mothers. Using thematic analysis, 5 themes were identified: (1) facing the reality of a pregnancy complicated by substance use, trauma, and loss, (2) finding a higher meaning, (3) dealing with the consequences, (4) managing the details of daily life, and (5) looking toward a future with my children. Moreover, the women described entering motherhood with uncertainty, fear, shame, and stress. We hope that these findings will lead to more compassionate nursing care for this population.

Cytokines and chemokines as biomarkers of ethanol-induced neuroinflammation and anxiety-related behavior: role of TLR4 and TLR2

Recent evidence supports the influence of neuroimmune system activation on behavior. We have demonstrated that ethanol activates the innate immune system by stimulating toll-like receptor 4 (TLR4) signaling in glial cells, which triggers the release of inflammatory mediators and causes neuroinflammation. The present study aimed to evaluate whether the ethanol-induced up-regulation of cytokines and chemokines is associated with anxiety-related behavior, 24 h after ethanol removal, and if TLR4 or TLR2 is involved in these effects. We used WT, TLR4-KO and TLR2-KO mice treated with alcohol for 5 months to show that chronic ethanol consumption increases the levels of cytokines (IL-1β, IL-17, TNF-α) and chemokines (MCP-1, MIP-1α, CX3CL1) in the striatum and serum (MCP-1, MIP-1α, CX3CL1) of WT mice. Alcohol deprivation for 24 h induces IFN-γ levels in the striatum and maintains high levels of some cytokines (IL-1β, IL-17) and chemokines (MIP-1α, CX3CL1) in this brain region. The latter events were associated with an increase in anxiogenic-related behavior, as evaluated by the dark and light box and the elevated plus maze tests. Notably, mice lacking TLR4 or TLR2 receptors are largely protected against ethanol-induced cytokine and chemokine release, and behavioral associated effects during alcohol abstinence. These data support the role of TLR4 and TLR2 responses in neuroinflammation and in anxiogenic-related behavior effects during ethanol deprivation, and also provide evidence that chemokines and cytokines can be biomarkers of ethanol-induced neuroimmune response.

Efficacy and tolerability of antidepressants in the treatment of adolescents and young adults with depression and substance use disorders: a systematic review and meta-analysis

AIMS

To measure the effectiveness of antidepressants for adolescents and young adults with co-occurring depression and substance use disorder.

DESIGN, SETTING AND PARTICIPANTS

Meta-analysis of randomized controlled clinical trials. A comprehensive literature search of PubMed, Cochrane, Embase, Web of Science and PsychINFO was conducted (from 1970 to 2013). Prospective, parallel groups, double-blind, controlled trials with random assignment to an antidepressant or placebo on young patients (age ≤ 25 years) who met diagnostic criteria of both substance use and unipolar depressive disorder were included. Five trials were selected for this analysis and included 290 patients.

MEASUREMENTS

Our efficacy outcome measures were depression outcomes (dichotomous and continuous measures) and substance-use outcomes (change of frequency or quantity of substance-use). Secondary analysis was conducted to access the tolerability of antidepressant treatment.

FINDINGS

For dichotomous depression outcome, antidepressants group was significantly more effective than placebo group [risk ratio (RR) = 1.21; 95% confidence interval (CI) 1.01-1.45], with low heterogeneity (I(2)  = 0%). Although no statistically significant effects for continuous depression outcome [standardized mean differences (SMD) = -0.13; 95% CI, -0.55 to 0.30] were found with moderate heterogeneity (I(2)  = 63%), subgroup analysis showed that the medicine group with a sample size of more than 50 showed statistically significant efficacy compared with the placebo group (SMD -0.53, 95% CI -0.82 to -0.25). Moreover, there was no significant difference for substance-use outcomes and tolerability outcomes between the medication and placebo groups.

CONCLUSIONS

Antidepressant medication has a small overall effect in reducing depression in young patients with combined depressive and substance-use disorders, but does not appear to improve substance use outcomes.

The frequency and nature of resolution of potential police provoked shooting encounters

Helping people in acute psychiatric crisis has become an increasingly common part of modern community policing. In certain extreme cases, police may be faced with a suicidal individual who intends to intentionally provoke police to shoot them. While fatalities are fortunately rare, anecdotal reports from frontline police suggest that these kinds of encounters are occurring on a regular basis. This paper explores 2350 psychiatric crisis incidents over an eight-month period in Victoria, Australia, and assesses the frequency and nature of potential police-provoked shootings resolved through non-fatal means. Contextual factors relating to the person's behaviour and police responses, and the person's psychiatric and criminal histories were considered to elucidate characteristics common to these incidents. Results suggest that police are potentially encountering a person who is suicidal and trying to provoke police to shoot them more than twice a week. These individuals share a number of common characteristics with those who have been fatally shot in similar circumstances and are quite different from those who attempt self-inflicted suicide. Results are discussed in relation to the impact of previous criminal contact from both the suspect and police perspectives.

Mikocka-Walus A, Keage H, Churches O, Andrews J. A novel treatment resource for co-occurring symptoms

Purpose

– This paper describes the development of a novel integrative self-directed treatment tool which uses cognitive behavioural therapy techniques to reduce anxiety symptoms in patients presenting to treatment for alcohol-related problems. More specifically, the purpose of this paper is to explore patient and health practitioner perceptions of the booklet, in order to determine its suitability and utility in the context of existing alcohol treatment services. The extent of cross-informant agreement between patient and health practitioner responses is also examined.

Design/methodology/approach

– This research utilises a cross-sectional qualitative research design using semi-structured interview methods with patients presenting to hospital for alcohol-related diseases/illnesses/accidents/injuries (n=15) and practitioners (n=10) working at inpatient, outpatient and residential substance treatment facilities.

Findings

– The present study found that the majority of patients (80 per cent) and practitioners (90 per cent) expressed a motivation to utilise the proposed booklet, agreeing that the booklet was a practical, achievable and educational resource for patients suffering from co-occurring anxiety symptoms in substance abuse facilities. Participants outlined limitations of the resource, suggesting that the booklet would be most suitable for patients with moderate to high cognitive ability, who also exhibit a motivation to change alcohol consumption and have access to additional support.

Practical implications

– Findings from the present study suggest that the booklet may be most effective in improving treatment accessibility and patient treatment seeking behaviours; rather than reducing practitioner-patient contact.

Originality/value

– This paper focuses on the development and utility of a novel resource suitable for substance abuse treatment facilities. The findings and feedback produced from the present study can assist with modifications of the intervention and in improving the effectiveness of future trials.

Enhancing health-care workers' understanding and thinking about people living with co-occurring mental health and substance use issues through consumer-led training

BACKGROUND

Stigma and judgemental assumptions by health workers have been identified as key barriers to accessing health care for people living with co-occurring mental health and substance use issues (dual diagnosis).

OBJECTIVE

To evaluate the effectiveness of consumer-led training by people with dual diagnosis in improving the knowledge, understanding and role adequacy of community health staff to work with this consumer group.

METHODS

A controlled before-and-after study design with four waves of quantitative data collection was used. Qualitative data were collected to explore participants' views about training. Participants were staff from two community health services from Victoria, Australia. Recruitment occurred across various work areas: reception, oral health, allied health, counselling and health promotion. At baseline, all participants attended a 4-h clinician-led training session. The intervention consisted of a 3-h consumer-led training session, developed and delivered by seven individuals living with dual diagnosis. Outcome measures included understanding of dual diagnosis, participants' feelings of role adequacy and role legitimacy, personal views, and training outcomes and relevance.

RESULTS

Consumer-led training was associated with a significant increase in understanding. The combination of clinician-led and consumer-led training was associated with a positive change in role adequacy.

CONCLUSIONS

Consumer-led training is a promising approach to enhance primary health-care workers' understanding of the issues faced by dual-diagnosis consumers, with such positive effects persisting over time. Used alongside other organizational capacity building strategies, consumer-led training has the potential to help address stigma and judgemental attitudes by health workers and improve access to services for this consumer group.

Reflections on capacity‐building initiatives in an Australian state

Purpose

The integration of health or social services is an enduring challenge and especially so in relation to people experiencing “dual diagnosis”, the co‐occurrence of mental health and substance use problems. The emergence of the “dual diagnosis” concept has highlighted the tension between specialist treatment for single problems and complex, individualised care. The purpose of this paper is to examine the evolving nature of dual diagnosis initiatives in an Australian state during recent decades.

Design/methodology/approach

Interpretive, case study analysis of policy documents and key informant interviews (19) illuminates the experience of dual diagnosis initiatives.

Findings

In the case of Victoria, dual diagnosis responsiveness has evolved slowly over the last 20 years, delayed by the inherent difficulty of practice change, a weak perception of need, interprofessional tensions and shortcomings in data collection, coordination and resources. Key enablers have been champions and leaders in policy, management and clinical practice, directive government policy and targeted funding. Achieving a wrap‐around service system entails investment in interpersonal relationship‐building and stigma reduction, as well as technical or structural changes.

Originality/value

The paper presents a unique and independent view of a 20‐year period and indicates progress in attitudinal change that merits wider acknowledgement and application to other settings throughout health and social care.

Individual differences in elevated plus-maze exploration predicted higher ethanol consumption and preference in outbred mice

Psychiatric illnesses, such as anxiety, are highly comorbid with drug use disorders in general and alcohol abuse in particular. Unfortunately, the causal role of anxiety in ethanol addiction is still unclear. We asked the question whether high anxiety predicts predilection of mice to voluntarily consume more alcohol than water. In the current study, we used the voluntary alcohol intake in two bottle choice drinking paradigm to explore whether high anxiety predicts higher alcohol preference and intake in outbred Tuck-Ordinary "TO" mice. To this end, mice were tested for their anxiety-like behavior using the elevated plus maze, open field and the marble burying test prior to voluntary continuous access to increasing concentrations of alcohol solutions. To assess their taste discrimination, mice had access to saccharin and quinine solutions. Results showed that compared to low-anxious mice (LAM), high-anxious mice (HAM) showed greater consumption and preference for ethanol but not for saccharin and quinine suggesting alterations in the rewarding effects of alcohol. Taken together, these findings suggest a correlative link between trait anxiety and the behavioral responses to ethanol.
