Headache Attributed to a Substance or Its Withdrawal

Identification of substances that may cause or trigger headache is important to start effective treatment early to prevent unnecessary suffering, deterioration in quality of life, and the development of chronic pain. Treatment in case of medication overuse and other chronic headache should be decisive and effective. Drug withdrawal and introduction of effective prophylactic medication for the underlying headache disorder should be the primary treatment strategy. Typical headache-inducing substances are nitric oxide, phosphodiesterase, cocaine, alcohol, histamine, carbon oxide, and calcitonin gene-related peptide. The withdrawal of caffeine, estrogen, and opioids is most often associated with the development of headache.

Association between breakfast skipping and psychosomatic symptoms among Canadian adolescents

This cross-sectional study aimed to examine the mediating roles of gender and substance use in the influence of breakfast skipping on psychosomatic symptoms. The study used data among a nationally-representative sample of 2855 Canadian adolescents who participated in the 2018 Health Behavior in School-aged Children (HBSC) survey. Sequential logistic regressions were used to estimate the associations between breakfast skipping and psychosomatic symptoms. Path analysis using a non-parametric bootstrapping technique tested the hypothesized mediating roles. Results showed that adolescents who skipped breakfast were 2.55 times more likely to report higher psychosomatic symptoms compared to non-breakfast skippers (AOR = 2.55; 95% CI = 1.75-3.82). The bootstrapping mediation models showed that breakfast skipping indirectly influenced psychosomatic symptoms through substance use and gender, accounting for 18.47% ( β = 0.0052, Boots 95% CI = 0.0025, 0.00730) and 10.70% ( β = 0.0091, Boots 95% CI = 0.0052, 0.0125), respectively, of the total effect. Our findings have important implications for targeted public and mental health interventions to address both breakfast skipping and psychosomatic symptoms among adolescents.  Conclusion: The study compellingly underscores the significance of incorporating gender-specific factors and substance use in understanding the correlation between breakfast skipping and psychosomatic symptoms. These insights hold importance for tailoring public health interventions to alleviate the prevalence of psychosomatic symptoms among adolescents by actively addressing breakfast skipping. What is Known: • Breakfast is considered the most important meal of the day due to its role in providing the brain with the energy necessary to enhance cognitive functions. • Adolescents commonly exhibit a prevalent lifestyle behaviour of skipping breakfast. What is New: • This study provides robust evidence supporting the association between breakfast skipping and elevated psychosomatic symptoms in adolescents. • Gender and substance use mediate this association, offering novel insights into the complex interplay that contributes to psychosomatic symptoms among this demographic group. • Longitudinal research is needed to unravel causal relationships and illuminate the underlying mechanisms of this intricate connection.

Unveiling the unique role of iron in the metabolism of methanogens: A review

Methanogens are the main participants in the carbon cycle, catalyzing five methanogenic pathways. Methanogens utilize different iron-containing functional enzymes in different methanogenic processes. Iron is a vital element in methanogens, which can serve as a carrier or reactant in electron transfer. Therefore, iron plays an important role in the growth and metabolism of methanogens. In this paper, we cast light on the types and functions of iron-containing functional enzymes involved in different methanogenic pathways, and the roles iron play in energy/substance metabolism of methanogenesis. Furthermore, this review provides certain guiding significance for lowering CH4 emissions, boosting the carbon sink capacity of ecosystems and promoting green and low-carbon development in the future.

Frequency of Smoking, Alcohol Consumption, and Substance Use in Relation to General Health Indicators in Guilan University of Medical Sciences

Background

The risk of substance use is increasing among university students, especially medical students. This study aimed to investigate the frequency of smoking, alcohol consumption, and substance use and its relationship with general health indicators among the students of Guilan University of Medical Sciences (GUMS) in 2020. The differences in the frequency of substance use were also investigated from 2005.

Methods

This was a cross-sectional analytical study conducted on 406 students of GUMS, Iran, in 2020. The data were collected through three online questionnaires including a demographic questionnaire, the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST), and the General Health Questionnaire (GHQ). The data were entered into SPSS software version 22 and analyzed using Chi-square, Fisher's Exact tests, and logistic regression at a significance level of 0.05.

Findings

In this study, 53.9% of the participants were female, 46.1% were male, and 54.4% of them experienced using substances in their lifetime. The highest prevalence of use was in consumers of tobacco (46.8%), alcoholic beverages (34.7%), and cannabinoid compounds (19%). Besides, 48.5% of the participants were suspected of having some degree of psychiatric disorders, among which depression (11.6%) and anxiety (8.4%) were the most common. Moreover, substance use during students' lifetime had a statistically significant association with anxiety, depression, and mental health.

Conclusion

The results of this study showed the prevalence of smoking, alcohol consumption, and substance use among the students of GUMS is worrying. The relationship between consumption and consumer's health indicators highlights the necessity of intervention and purposeful planning by policymakers in this field.

Pathways to care for substance use treatment among tribal patients at a psychiatric hospital: A comparative study

Objectives

According to the national mental health survey, substance use disorders (SUDs) are prevalent in 22.4% of the population above 18 years, whereas the same is 26% among the tribal population. The treatment gap is also high in substance-addictive disorders. Our study aimed to compare the severity of substance use, pathways to psychiatric care, and treatment-seeking behavior among the tribal and non-tribal populations.

Materials and Methods

The study was conducted at a tertiary psychiatric teaching institute in India. It was a cross-sectional comparative study. Patients fulfilling the International Classification of Disease 10 diagnostic criteria of mental and behavioral disorders due to substance use, with active dependence, were taken without comorbidity. Forty patients in tribal and non-tribal groups were recruited with consecutive sampling. The samples were assessed with a semi-structured interview schedule, addiction severity index, attitudes toward help-seeking, and pathways-to-care.

Results

Excessive substance use median was for 7.00 (± 5.00) years in tribal and 6.00 (± 4.00) years in non-tribal; in tribal, substance intake was younger than non-tribal (P = 0.167), and general health-care system more distance than the non-tribal (P < 0.001). Around 65% of the persons with SUD never consulted their general practitioner and primary health-care facilities. Alcohol severity was higher in the tribal population than in the non-tribal population. The cannabis and opioid severity was high in the non-tribal population. Help-seeking behavior was deficient in both groups.

Conclusion

Most of the substance abuse tribal and non-tribal populations reach healthcare very late and do not consider it as a health issue initially. The major reason for the delayed pathway is a lack of awareness about mental health care facilities and stigma in both populations. The stigma is high in non-tribal communities compared to the tribal community. There is a need to improve the identification and treatment of alcohol morbidity in primary care.

Trends of cannabis use and related harms before and after legalization for recreational purpose in a developing country in Asia

BACKGROUND

Thailand was the first country in Asia to legalize the use and purchase of cannabis leaves in February 2021 and the whole plant in June 2022 after the 2019 allowance for medical purposes. The study explored trends in cannabis use in Thailand before and after the recreational cannabis allowance was imposed.

METHODS

Cannabis and other variables of substance use, cannabis use disorder, and attitude towards cannabis of the Thai population aged 18 to 65 years in 2019 (n = 5,002), 2020 (n = 5,389) and 2021 (n = 5,669) were obtained from annual surveys conducted in the last two months of each year by the Centre for Addiction Studies. The surveys were repeat cross-sectional surveys of the general population of Thailand. Repeated variables from at least two annual surveys were included for analysis using the Chi-square test and the t-test.

RESULTS

The prevalence of cannabis use in the past year had increased from 2.2% in 2019 to 2.5% and 4.2% in 2020 and 2021 respectively, while those of methamphetamine, alcohol, and tobacco use had decreased. Trends in past-year drinking/eating cannabis products had increased, especially among the middle age group (40-49 years) from 2.1% (95% confidence interval (CI): 1.3, 3.1) in 2019 and 1.1% (95% CI: 0.6, 1.9) in 2020 to 3.8% (95% CI: 2.8, 5.0) in 2021. The younger population aged 18-19 had an increase in cannabis smoking from 0.9% (95% CI: 0.1, 3.3) in 2019 to 2.0% (95% CI: 0.5, 5.1) and 2.2% (95% CI: 0.7, 5.1) in 2020 and 2021 respectively. Symptoms of cannabis use disorder among cannabis users increased from 2019 to 2020 and then reversed afterwards in 2021. Thais had greater health knowledge about the benefits and harms of cannabis and had attitudes toward more harm of cannabis in 2021; however, 35.6% or a third of the sample in 2021 truly believed that cannabis was a cure for cancer, and 23.2% or one-fourth were uncertain or did not believe that cannabis was addictive.

CONCLUSIONS

Although most of the substances had a lower prevalence of use during the COVID-19 pandemic in Thailand, cannabis had a higher use after legalization. Thai youth had a growing trend to smoke cannabis.

Sleep profile status based on substance use, lipids and demographic variables in Tabari cohort study

BACKGROUND

This study aims to investigate the situation of sleep profile and its related factors in the Tabari Cohort Tabari (TCS) population.

METHODS

The information of 10255 of the Tabari cohort population in the enrolment phase was used in this study. The sleep profile data was collected and recorded by trained questioners. The sleep duration in day & night, the time interval between going bed and falling asleep, continuous use of sedatives, involuntary nap, limb hypermobility during sleep and shift working were determined for each person. Data analysis was performed by independent T test and Pearson correlation coefficient.

RESULTS

Mean, standard deviation, median, minimum and maximum of sleep duration in this population were 7.6, 1.6, 7.5, 0.5 and 17 h. Frequency of sleeping less than 6 h, 6-10 h and more than 10 h were 1168(11.4%), 8463(82.5%) and 624(6.1%) respectively. Prevalence of sleeping more than 10 h among men and women were 5% and 6.8% respectively (P < 0.001). Prevalence of sedative routine use among men and women were 4.7% and 9.6% respectively (P < 0.001). There were significant relationships between sleep duration and area residence, age group (P < 0.001), education level (P < 0.001), socioeconomic level (P < 0.001), triglyceride (P = 0.002), HDL-cholesterol (P = 0.013) and Cholesterol total (P = 0.021). There was a negative correlation between age and sleep duration (r = -0.062, P < 0.001).

CONCLUSION

The results showed the association of the quality and quantity of sleep with personal, social, environmental and biological factors such as gender, age, economic status, educational status, and lipid profile. Therefore without proper intervention, the incidence of outcomes associated with these risk factors can be predicted in TCS In later years.

Neurobehavioral effects of environmental enrichment and drug abuse vulnerability: An updated review

Environmental enrichment consisting of social peers and novel objects is known to alter neurobiological functioning and have an influence on the behavioral effects of drugs of abuse in preclinical rodent models. An earlier review from our laboratory (Stairs and Bardo, 2009) provided an overview of enrichment-specific changes in addiction-like behaviors and neurobiology. The current review updates the literature in this extensive field. Key findings from this updated review indicate that enrichment produces positive outcomes in drug abuse vulnerability beyond just psychostimulants. Additionally, recent studies indicate that enrichment activates key genes involved in cell proliferation and protein synthesis in nucleus accumbens and enhances growth factors in hippocampus and neurotransmitter signaling pathways in prefrontal cortex, amygdala, and hypothalamus. Remaining gaps in the literature and future directions for environmental enrichment and drug abuse research are identified.

Young Adult Substance Use and Healthcare Use Associated With Screening, Brief Intervention and Referral to Treatment in Pediatric Primary Care

PURPOSE

Screening, brief intervention, and referral to treatment (SBIRT) may impact future comorbidity and healthcare utilization among adolescents screening positive for substance use or mood problems.

METHODS

In a randomized trial sample, we compared an SBIRT group to usual care for substance use, mental health, medical diagnoses, and healthcare utilization over 7 years postscreening.

RESULTS

In logistic regression models adjusting for patient characteristics, the SBIRT group had lower odds of any substance (Odds Ratio[OR] = 0.80, 95% Confidence Interval [CI] = 0.66-.98), alcohol (OR = 0.69, 95% CI = 0.51-0.94), any drug (OR = 0.73, 95% CI = 0.54-0.98), marijuana (OR = 0.70, 95% CI = 0.50-0.98), and tobacco (OR = 0.83, 95% CI = 0.69-1.00) diagnoses, and lower odds of any inpatient hospitalizations (OR = 0.59, 95% CI = 0.41-0.85) compared with usual care. Negative binomial models examining number of visits among adolescents with at least one visit of that type found that those in the SBIRT group had fewer primary care (incidence rate ratio[iRR] = 0.90, p < .05) and psychiatry (iRR = 0.64, p < .01) and more addiction medicine (iRR = 1.52, p < .01) visits over 7 years compared with usual care. In posthoc analyses, we found that among Hispanic patients, those in the SBIRT group had lower odds of any substance, any drug and marijuana use disorder diagnoses compared with usual care, and among Black/African American patients, those in the SBIRT group had lower odds of alcohol use disorder diagnoses compared with usual care.

DISCUSSION

Beneficial effects of adolescent SBIRT on substance use and healthcare utilization may persist into young adulthood.

A novel home- and community-based mobile outreach detoxification service for individuals identifying problematic substance use: implementation and program evaluation

SETTING

Substance use remains a pervasive public health issue throughout Canada, exerting substantial economic, social, and political pressure on health care systems, while impacting lives of affected individuals. The advent of COVID-19 has been doubly perilous; it restricts existing programming, while exacting a worsening toll on mental health and substance use fronts across the demographic landscape.

INTERVENTION

In response to the crisis, the Mobile Withdrawal Management Service (MWMS) was established in 2019 through a Winnipeg-based community health centre. MWMS is a community-based outreach withdrawal service that supports individuals for up to 30 days. Clients may choose where services are accessed in the community, including their own home. For those without safe housing, short-term accommodation is offered. Additionally, Indigenous cultural support, peer support, trauma counselling, and linkage to primary care are available.

OUTCOMES

The MWMS approach is resolutely patient-centred. The program meets people where they are at, both figuratively and literally. Agility and adaptability-particularly in the context of substance use treatment-is uniquely advantageous in maintaining service delivery to the broad demographic cross-section revealed in the data. Moreover, relative to inpatient detoxification services, MWMS holds significant potential for system-wide cost savings.

IMPLICATIONS

The presented approach addresses a significant gap in addiction services. There is substantial capacity for both increased access and system savings with implementation of this approach. Furthermore, the principles behind the program are readily transferable to different contexts and easily modifiable to local conditions. There is particular potential for servicing hard-to-reach populations, with respect to both physical and social geography.

Drug and Alcohol Use with Condomless Anal Sex among Men Who Have Sex with Men in Melbourne, Australia: A Retrospective Data Analysis from 2011 to 2017

Rises in condomless anal sex among men who have sex with men (MSM) have been reported over the last decade but there is less certainty about the role that drugs, alcohol, play in this change. We examined the changes in drug and alcohol use among 22,255 MSM reporting condomless anal sex at Melbourne Sexual Health Centre in 2011-2017. There was a 7% annual increase in using drugs before and/or during condomless anal sex but a 3% annual reduction in condomless anal sex while drunk. MSM taking PrEP were more likely to report condomless anal sex with drug use (AOR: 1.21; 95%CI: 1.07-1.37) and alcohol use (AOR: 1.29; 95%CI: 1.14-1.46) compared with MSM not taking PrEP.

Consideration of sex and gender differences in addiction medication response

Substance use continues to contribute to significant morbidity and mortality in the United States, for both women and men, more so than another other preventable health condition. To reduce the public health burden attributable to substances, the National Institute on Drug Abuse and the National Institute on Alcohol Abuse and Alcoholism have identified that medication development for substance use disorder is a high priority research area. Furthermore, both Institutes have stated that research on sex and gender differences in substance use medication development is a critical area. The purpose of the current narrative review is to highlight how sex and gender have been considered (or not) in medication trials for substance use disorders to clarify and summarize what is known regarding sex and gender differences in efficacy and to provide direction to the field to advance medication development that is consistent with current NIH 'sex as a biological variable' (SABV) policy. To that end, we reviewed major classes of abused substances (nicotine, alcohol, cocaine, cannabis, opioids) demonstrating that, sex and gender have not been well-considered in addiction medication development research. However, when adequate data on sex and gender differences have been evaluated (i.e., in tobacco cessation), clinically significant differences in response have been identified between women and men. Across the other drugs of abuse reviewed, data also suggest sex and gender may be predictive of outcome for some agents, although the relatively low representation of women in clinical research samples limits making definitive conclusions. We recommend the incorporation of sex and gender into clinical care guidelines and improved access to publicly available sex-stratified data from medication development investigations.

A "4D" systemic view on meridian essence: Substantial, functional, chronological and cultural attributes

The term Jingluo, translated as meridian or channel, is a core component of traditional Chinese medicine (TCM) and has played a fundamental role in guiding the clinical practice of acupuncture for thousands of years. However, the essence of the meridian remains elusive and is a source of both confusion and debate for researchers. In this study, a "4D" systemic view on the essence of the meridian, namely substantial, functional, chronological, and cultural dimensions, was proposed based on a review of the ancient medical classics, recent research developments, and results from clinical practice. Previous studies have primarily focused on the substantial dimension of the meridian system, with scant interpretation about its functional domain. Neither systemic data nor evaluations have been adequately documented. Additionally, a limited but increasing number of studies have focused on the chronological and cultural dimensions. More investigations that embody the holistic concept of TCM and integrate the systemic modes and advanced techniques with dominant diseases of TCM need to be performed to obtain a more comprehensive understanding of the essence of meridians. The goal of this study is to yield useful information in understanding the essence of meridians and provide a reference and perspective for further research.

State lockdown policies, mental health symptoms, and using substances

Objective

Previous literature finds an increase in depressive symptoms, substance use, and suicidal ideation following the COVID-19 pandemic in the US – suicides do not appear to increase. We examine whether 1) state lockdown policies in the US precede an increase in mental health symptoms; and 2) the extent to which using substances amplifies or attenuates the relation.

Methods

We specified, as our exposure variable, the timing of state-level lockdown orders. We used, as the outcome variable, the 4-item Patient Health Questionnaire (PHQ-4) that measures anxiety and depression symptoms. We utilized the Understanding America Study (UAS), a nationally representative sample of 7,597 adults across 50 states in the US, surveyed biweekly between March 10, 2020 and November 11, 2020. Linear fixed effect analyses controlled for time-invariant individual factors, as well as employment status, household income, and previous mental health diagnosis.

Results

Regression results indicate an increase in PHQ-4 scores of approximately 1.70 during lockdown, relative to no lockdown (p < 0.05). Relative to no lockdown, an increase in alcohol use corresponds with a 0.08 unit decrease in PHQ-4 scores during lockdown (p < 0.05).

Conclusion

State lockdown policies precede greater mental health symptoms. Increases in consuming alcohol attenuates the relation between state lockdown policies and mental health symptoms. Results may portend greater addiction following the pandemic warranting further investigation into utilization of substance use treatment.

The Use of Chatbots as Supportive Agents for People Seeking Help with Substance Use Disorder: A Systematic Review

INTRODUCTION

The use of chatbots in healthcare is an area of study receiving increased academic interest. As the knowledge base grows, the granularity in the level of research is being refined. There is now more targeted work in specific areas of healthcare, for example, chatbots for anxiety and depression, cancer care, and pregnancy support. The aim of this paper is to systematically review and summarize the research conducted on the use of chatbots in the field of addiction, specifically the use of chatbots as supportive agents for those who suffer from a substance use disorder (SUD).

METHODS

A systematic search of scholarly databases using the broad search criteria of ("drug" OR "alcohol" OR "substance") AND ("addiction" OR "dependence" OR "misuse" OR "disorder" OR "abuse" OR harm*) AND ("chatbot" OR "bot" OR "conversational agent") with an additional clause applied of "publication date" ≥ January 01, 2016 AND "publication date" ≤ March 27, 2022, identified papers for screening. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to evaluate eligibility for inclusion in the study, and the Mixed Methods Appraisal Tool was employed to assess the quality of the papers.

RESULTS

The search and screening process identified six papers for full review, two quantitative studies, three qualitative, and one mixed methods. The two quantitative papers considered an adaptation to an existing mental health chatbot to increase its scope to provide support for SUD. The mixed methods study looked at the efficacy of employing a bespoke chatbot as an intervention for harmful alcohol use. Of the qualitative studies, one used thematic analysis to gauge inputs from potential users, and service professionals, on the use of chatbots in the field of addiction, based on existing knowledge, and envisaged solutions. The remaining two were useability studies, one of which focussed on how prominent chatbots, such as Amazon Alexa, Apple Siri, and Google Assistant can support people with an SUD and the other on the possibility of delivering a chatbot for opioid-addicted patients that is driven by existing big data.

DISCUSSION/CONCLUSION

The corpus of research in this field is limited, and given the quality of the papers reviewed, it is suggested more research is needed to report on the usefulness of chatbots in this area with greater confidence. Two of the papers reported a reduction in substance use in those who participated in the study. While this is a favourable finding in support of using chatbots in this field, a strong message of caution must be conveyed insofar as expert input is needed to safely leverage existing data, such as big data from social media, or that which is accessed by prevalent market leading chatbots. Without this, serious failings like those highlighted within this review mean chatbots can do more harm than good to their intended audience.

The effect of opium on severity of COVID-19 infection:An original study from Iran

Background: The COVID-19 infection is a novel virus without any specific targeted therapies; thus, focusing on primary epidemiologic concerns, preventive strategies, risk factors, exacerbation factors, and mortality-related factors are of great importance to better control this disorder. There are some controversies about the factors associated with COVID-19 in different theories, and addiction is no exception.

Methods: We conducted a large cross-sectional study of 513 hospitalized Iranian patients with COVID-19 infection to evaluate the severity of disease courses in patients with or without history of opium addiction. We recorded these data retrospectively after patients’ discharge from the hospital. For the quantitative data, we used independent-samples t and Mann-Whitney tests. The qualitative data were calculated using Fisher exact and chi-square tests in IBM SPSS Statistics Version 22. Also, p<0.05 was considered statistically significant.

Results: There was no significant difference regarding mean days of hospitalization in opium positive and negative groups (7.95±8.39 vs 8.35±5.11, respectively) (p=0.771); however, the need for intensive care unit (ICU) admission was significantly higher in the opium positive group (36% vs 11%) (p=0.005). The mean days of ICU stay was significantly higher in the opium positive group (2.36±3.81 vs 0.86±2.90) (p=0.026). The percentage of febrile patients, anosmia/hyposmia, and dysgeusia at the initiation of hospitalization was significantly lower in the opium positive group (39% vs 66%; 8% vs 23%; 8% vs; 20%, respectively) (p=0.002, 0.018, and.031, respectively). In the laboratory tests, only the white blood cell (WBC) count and the segmented cells were higher in the opium positive group (10.1±6.60 vs 7.38±4.14 and 73±20.47 vs 56.5±32.60, respectively) (p=0.018 and.001, respectively) and lymphocytes were lower in the opium positive (15.60±8.25 vs18.70±10.12) (p=0.048). Opium addicts had a significantly lower rate of azithromycin and lopinavir/ritonavir prescription in their initiation therapy (19% vs 34%, and 47% vs 70%, respectively) (p=0.038 and 0.012, respectively).

Conclusion: Opium addict patients with COVID infection may be more febrile and experience more disease-specific symptoms and more severe disease course. These patients may show more evidence of laboratory inflammation and probable superinfections, so may manage with more caution and somehow different therapeutic regimen.

The relationship of lifetime substance-use disorder with family functioning, childhood victimisation, and depression, among juvenile offenders in Malaysia

INTRODUCTION

Adolescent substance use is a multifactorial social issue that leads to detrimental outcomes. The aim of this study is to understand the association of a lifetime history of substance abuse or dependence with family functioning, childhood victimisation, and depression, among adolescent male inmates in a juvenile detention centre in Malaysia.

METHODS

This study was cross-sectional involving 230 inmates and was conducted in a juvenile detention centre in Malaysia. The mean age of the participants was 16.65 years, with the highest percentage from the Malay ethnicity (87.8% where n = 202). The Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID), Adolescent Alcohol and Drug Involvement Scale (AADIS), Family Adaptability and Cohesion Evaluation Scale (FACES) IV and Juvenile Victimization Questionnaire Second Revision (JVQ-R2) were used as instruments.

RESULTS

The prevalence of a lifetime history of substance abuse and substance dependence is 72.6% and 58.3%, respectively. A lifetime history of substance abuse and dependence had a significant association with age, race, religion, and peer/sibling victimisation. Further analysis reveals that an increase in age can be a predictor of both lifetime history of substance abuse and dependence while peer/sibling victimisation may predict lifetime history of substance abuse. There was no significant association of lifetime substance-use disorder with family functioning and depression in the juvenile offenders.

CONCLUSIONS

Adolescents exposed to peer/sibling victimisation might be at a higher risk of developing a substance-use disorder. At-risk groups need to be identified, assessed, and have intervention early to prevent adverse outcomes.

Illicit Drug Use in Older Adults: An Invisible Epidemic?

Illicit drug use/misuse among older adults is understudied, although current trends point to older adults being the fastest-growing segment in the United States and other developed countries. There is a need for further insight into drug use patterns in older adults, who face their own set of socioeconomic, medical, and psychiatric problems. We reviewed the literature for data related to use/misuse of heroin and stimulants (cocaine, amphetamines, and methamphetamines) among people over the age of 40 years. We focused on prevalence rates of use/misuse of these substances, comorbidities, diagnostic challenges, screening tools, and treatment recommendations specific to the geriatric population.

Effects of the "Unplugged" school-based substance use prevention program in Nigeria: A cluster randomized controlled trial

BACKGROUND

School-based programs are the most convenient interventions to tackle substance use among youth. "Unplugged" is a Social Influence universal school curriculum developed and tested in the "EU-Dap" project. In 2015, Nigeria implemented a large-scale project to promote healthy lifestyles in schools, families and communities. Within the project, the effectiveness of "Unplugged" was evaluated through a cluster randomized controlled trial.

METHODS

The program was adapted to the Nigerian context, assembling suggestions from monitoring forms and interviews, and performing fidelity checks on content and method. Thirty-two secondary schools were extracted from a list provided by the Federal Ministry of Education, and randomly allocated to intervention and control arms. A self-completed anonymous questionnaire was used for baseline and follow-up surveys. The analysis sample finally included 2685 pupils (mean age 14.2 years). Multilevel models were run to estimate program effects on prevalence of self-reported cigarettes, alcohol, and marijuana use. Mediation analysis was performed to identify possible mediators of program effect on alcohol use.

RESULTS

Unplugged significantly reduced the prevalence of recent alcohol use in intervention vs control pupils. The effect on prevalence of cigarette and marijuana use was not statistically significant. The program prevented progress and encouraged regress across stages of intensity of alcohol use. Negative beliefs, risk perceptions, and class climate mediated the effect of Unplugged on alcohol use.

CONCLUSIONS

Unplugged was effective in preventing alcohol use improving beliefs, class climate and risk perceptions among Nigerian students. The implementation of the program at a larger scale in the country should be supported.

Emotional and behavioural pathways to adolescent substance use and antisocial behaviour: results from the UK Millennium Cohort Study

This study examines the emotional and behavioural pathways to adolescent substance use and antisocial behaviour. Using a sample of 17,223 participants from the UK Millennium Cohort Study, we applied parallel-process growth mixture modelling on emotional and behavioural symptoms in those aged 3-14 and employed latent class analysis to identify patterns of substance use and antisocial behaviours at age 14. We then performed a multinomial regression analysis to explore the association between emotional and behavioural trajectories and patterns of adolescent substance use and antisocial behaviours, including sociodemographic, family, and maternal factors. We found five trajectories of emotional and behavioural symptoms and four classes of adolescence substance use and antisocial behaviour. Children and adolescents in the 'high externalising and internalising' and 'moderate externalising' trajectories were more likely to belong to any problematic behaviour class, especially the 'poly-substance use and antisocial behaviours' class. Inclusion in the 'moderate externalising and internalising (childhood limited)' class was associated with higher odds of belonging to the 'alcohol and tobacco' class. These associations remained significant after adjusting for important sociodemographic and contextual factors, such as maternal substance use, poverty, and parental status. Interventions on adolescent health promotion and risk behaviour prevention need to address the clustering of substance use and antisocial behaviour as well as the significant influence of early and chronic internalising and externalising symptoms on the aetiology of these behaviours.

A longitudinal examination of alcohol cessation and academic outcomes among a sample of Canadian secondary school students

INTRODUCTION

The negative effects of alcohol consumption on learning ability and intellectual development of youth may be recovered after cessation. This study explored to what extent reduction or complete cessation of alcohol consumption affects school performance of secondary school students.

METHODS

Alcohol use was self-reported by 37,223 grade 9-12 students attending 89 secondary schools across Ontario (n = 79) and Alberta (n = 10), Canada, participating in the COMPASS study over four years (school years 2013-14 to 2016-17). Measures included past-year frequency of drinking and frequency of binge drinking. A first-order autoregressive multinomial logistic regression was used to establish the impact of reduction or cessation of alcohol use on school performance.

RESULTS

During follow-up, 1465 (6.4%) reductions and 1903 (8.3%) cessations in alcohol consumption, and 1447 (10.1%) reductions and 2147 (14.9%) cessations of binge drinking were reported. Male students reported more cessation in both drinking (9.7% male vs 7.1% female) and binge drinking (15.6% male vs 14.4% female), though female students had higher rates of reductions. Students who quit or reduced their drinking or binge drinking were less likely to skip classes, leave their homework incomplete, or expect to get or to aspire to educational qualifications above a high school diploma compared to those who continued their alcohol use.

CONCLUSIONS

Aside from health benefits, reduction or cessation of alcohol use may improve students' academic rigor. Prioritising school-based alcohol prevention efforts may therefore be beneficial for aspects of academic performance.

Effectiveness of N-acetylcysteine in Treating Clinical Symptoms of Substance Abuse and Dependence: A Meta-analysis of Randomized Controlled Trials

Objective

Treatment with N-acetylcysteine (NAC) is believed to reduce the clinical symptoms among individuals with substance abuse or dependence. We conducted a meta-analysis of randomized controlled trials to evaluate the effectiveness of NAC in treating substance abuse and dependence.

Methods

PubMed, EMBASE, ClinicalTrials.gov registry, and the Cochrane Library were searched for trials published before June 2020.

Results

A total of 16 trials were analyzed. The treatment effectiveness domains assessed in this study were craving and depressive symptoms, withdrawal syndrome, adverse events, and smoking frequency. Standardized mean difference (SMD), weighted mean difference (WMD), and odds ratio (OR) were used for evaluation where appropriate. A significant decrease in craving symptoms was observed in the NAC treatment group compared with the control group (SMD, −0.67; 95% confidence interval [CI], −1.21 to 0.21). When withdrawal and depressive symptoms were considered as a single domain, the NAC treatment group demonstrated a significantly higher overall improvement than the control group (SMD, −0.35; 95% CI, −0.64 to −0.06). No between-group differences in term of the OR of adverse events (OR, 1.18; 95% CI, 0.68 to 2.06) and a non-significant trend toward reduction in smoking frequency was observed in the NAC treatment group compared with the control group (WMD, −3.09; 95% CI, −6.50 to 0.32).

Conclusion

NAC provides certain noticeable benefits in attenuating substance craving and might help alleviate depressive symptoms and withdrawal syndrome. Precautious measures should be considered when using NAC although no difference in adverse effects was found between NAC treatment and control group.

Adverse childhood experiences and co-occurring psychological distress and substance abuse among juvenile offenders: the role of protective factors

OBJECTIVE

The purpose of this study was to estimate associations between cumulative exposure to adverse childhood experiences (ACEs), protective factors, and co-occurrence among male and female juvenile offenders.

STUDY DESIGN

Cross-sectional study.

METHODS

Validated measures of ACEs, internal resilience, external youth assets, psychological distress, and substance abuse were collected from 429 youths involved in the juvenile justice system in Nevada. A three-level outcome variable was created using the psychological distress and substance use measures: no problems, one problem, or co-occurring problems. Hierarchical multinomial logistic regression models were used to determine the independent, direct, and moderating impact of the protective factors on ACEs and the outcome.

RESULTS

Internal resilience, family communication, school connectedness, peer role models, and non-parental adult role models were associated with lower odds of co-occurrence compared to having no problems (adjusted odds ratios [AORs] ranged from 0.11 to 0.33). When ACEs were added to the model, internal resilience and all assets except for one (non-parental adult role models) continued to offer protection against co-occurrence. Internal resilience was the only protective factor that significantly moderated the association between ACEs and co-occurrence (AOR, 0.24; 95% CI, 0.06, 0.99).

CONCLUSION

Most protective factors decreased co-occurring mental health and substance abuse problems in the presence of ACE exposure and internal resilience moderated the relationship between ACEs and co-occurrence. Juvenile justice systems should use positive youth development approaches to help prevent co-occurrence among youths.

Substance use among refugees in three Lebanese camps: A cross-sectional study

BACKGROUND

There is a strong link between conflict exposure and ill health, including substance use. However, this widely acknowledged problem has not been studied yet in refugee camps in Lebanon.

AIM

To investigate substance use among civilians following war or displacement, and to assess its association with socio-demographic characteristics.

METHOD

Cross-sectional observational study carried out in three Palestinian camps in Lebanon using the World Health Organization Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). Participants were Palestinian adults born in Lebanon and Palestinian and Syrian adults recently displaced from Syria due to war. The percentage of people reporting substance use and the associations between lifetime and last three months substance use and demographic features were assessed using a multivariate logistic regression.

RESULTS

In general, lifetime substance use was higher among Palestinians born in Lebanon compared to Syrians and Palestinians displaced from Syria (OR 7.241, 95% CI [3.781-13.869], P <0.0001). Results from ASSIST score during last three months showed that moderate and high-risk use of cannabis and cocaine were higher among Palestinians born in Lebanon than Palestinians and Syrians displaced from Syria. The multivariate analysis showed that women had lower lifetime (OR 0.188, 95%CI [0.080-0.442], P <0.0001) and lower last three months substance use than men, whereas single people were more likely to use substances than married people (OR: 2.78, 95%CI [1.588-4.866], P <0.0001). Tobacco was significantly associated with higher risk of substance use.

CONCLUSION

These findings suggest a higher rate of lifetime substance use among Palestinians born in Lebanon than in Palestinians and Syrians recently displaced from Syria. Substance use is influenced by different socio-demographic factors in the two groups of refugees. However, many factors other than socio-demographic characteristics and refugee status may influence substance use, particularly quality of life and health status that should be assessed in future studies.

Clinical Efficacy and Possible Mechanism of Endoscopic Vidian Neurectomy for House Dust Mite-Sensitive Allergic Rhinitis

BACKGROUND/AIMS

Endoscopic vidian neurectomy (EVN) for allergic rhinitis (AR) has good clinical effects. However, the pathophysiological basis of the effect of EVN on AR is still poorly understood. This study aimed to investigate the efficacy of EVN on house dust mite (HDM)-sensitive AR and the dynamic changes of serum immunoglobulin E and some immune regulatory factors.

METHODS

Twenty HDM-sensitive AR patients were treated with bilateral EVN (EVN group), 15 HDM-sensitive AR patients were treated with subcutaneous immunotherapy (SCIT group), and 15 healthy subjects served as healthy controls. Quality of daily life was assessed by the scores of the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQs). The visual analog scale was used to assess clinical efficacy. Serum molecules were measured by ELISA and the UNICAP system.

RESULTS

Compared with the SCIT group, the RQLQs in the EVN group were lower 12 months after treatment (both p < 0.05). There was no significant difference in improving nasal itching and sneezing (both p > 0.05), but the clinical efficacy of bilateral EVN was greater than SCIT in improving nasal obstruction, rhinorrhea, eye itching, and lachrymation 12 months after treatment (all p < 0.05). Compared with before treatment, the serum levels of total immunoglobulin E (tIgE), Dermatophagoides pteronyssinus- and Dermatophagoides farinae-specific immunoglobulin E (sIgE), and tumor necrosis factor (TNF)-α in the EVN group and the serum levels of TNF-α and interleukin-4 in the SCIT group were lower 12 months after treatment (all p < 0.05).

CONCLUSION

The short-term efficacy of bilateral EVN is more effective than SCIT in treating HDM-sensitive AR. This may be because the surgery reduced the tIgE and sIgE levels. TNF-α may be involved in the therapeutic mechanism.

Prevalence and Sociodemographic Determinants of Substance Use in Turkey

BACKGROUND

Substance use disorder is a serious public health problem. It is essential to know who is prone to substance use in order to adopt appropriate measures.

OBJECTIVES

This study aims to determine the use prevalence ratios of substance use (tobacco, alcohol, cannabis, cocaine, synthetic cannabinoids, ecstasy, and others) in a large-scale sample of a general population. It also intends to examine related sociodemographic factors.

METHODS

This study is based on a cross-sectional survey conducted with a nationally representative sample of 24,494 individuals in face-to-face interviews conducted by a trained team of 125 clinical psychologists.

RESULTS

Lifetime prevalence of single substance use and polysubstance use are 4.5 and 2.6%, respectively (nicotine and alcohol excluded). Age, gender, education level, and marital status are important sociodemographic determinants for other substance use. Similarly, smoking and alcohol consumption are important determinants for other substance use. The multinomial regression analysis results showed that compared with adults aged 39 years and older, early-emerging adults (aged 18-23 years), late-emerging adults (aged 24-29 years), and young adults (aged 30-39 years) are more likely to turn to single substance use and polysubstance use.

CONCLUSION

Tobacco, alcohol, and other substance use are serious health concerns in Turkey. Sociodemographic status is an important determinant of several aspects of tobacco, alcohol, and other substance use and, therefore, should be examined thoroughly to be able to develop effective protective and preventive strategies.

I just knew that something was not right! Coping strategies of parents living with adolescents misusing substances

Substance misuse is a major problem affecting young people of all races, globally and in South Africa. This article focuses on the coping strategies of parents living with adolescents misusing substances. It is based on a study that received an in-depth understanding of the experiences, challenges, and coping strategies of parents living with adolescents abusing chemical substances in the community of Ramotse in Hammanskraal, Gauteng. A qualitative research approach with purposive and snowball sampling was used. Data was collected through semi-structured interviews and analysed using Tesch's eight steps. Data verification was conducted using Guba's model. The findings showed that most parents living with adolescents misusing substances are struggling to cope with their day-to-day lives. The findings highlighted the following themes which were: Parents avoided talking to adolescents to avoid pain and hurt, parents received comfort in their religion by praying or going to church, parents get spiritual support from the church and their pastors, parents opted to give the adolescents money and finally parents shared that they still have hope that their adolescent child's behaviour will change.

Assessment and treatment of substance use in adults with ADHD: a psychological approach

Over half of young people and adults diagnosed with Attention Deficit Hyperactivity Disorder [ADHD] also have substance use disorder [SUD]. Their use of substances may arise from an attempt to self-medicate and/or to cope with their difficulties. This manuscript reviews key research in the literature and identifies that traditional SUD psychological interventions are an effective treatment for those presenting with a dual diagnosis of ADHD and SUD. However, typically, this is only available to those presenting to specialist SUD services for treatment of harmful use and/or dependency. This misses an opportunity to intervene much earlier, before drug use escalates to these levels. The manuscript aims to provide practical guidance for healthcare practitioners, by detailing a psychological framework for earlier assessment and intervention of problematic drug use in young people and adults with ADHD. Specific techniques are outlined drawing on psychoeducation, motivational interviewing and cognitive behavioural therapy in a phased approach to address factors that motivate initial use of substances and those that maintain use.

Physical activity and the prevention, reduction, and treatment of alcohol and other drug use across the lifespan (The PHASE review): A systematic review

The aim of this review is to systematically describe and quantify the effects of PA interventions on alcohol and other drug use outcomes, and to identify any apparent effect of PA dose and type, possible mechanisms of effect, and any other aspect of intervention delivery (e.g. key behaviour change processes), within a framework to inform the design and evaluation of future interventions. Systematic searches were designed to identify published and grey literature on the role of PA for reducing the risk of progression to alcohol and other drug use (PREVENTION), supporting individuals to reduce alcohol and other drug use for harm reduction (REDUCTION), and promote abstinence and relapse prevention during and after treatment of alcohol and other drug use (TREATMENT). Searches identified 49,518 records, with 49,342 excluded on title and abstract. We screened 176 full text articles from which we included 32 studies in 32 papers with quantitative results of relevance to this review. Meta-analysis of two studies showed a significant effect of PA on prevention of alcohol initiation (risk ratio [RR]: 0.72, 95%CI: 0.61 to 0.85). Meta-analysis of four studies showed no clear evidence for an effect of PA on alcohol consumption (Standardised Mean Difference [SMD]: 0.19, 95%, Confidence Interval -0.57 to 0.18). We were unable to quantitatively examine the effects of PA interventions on other drug use alone, or in combination with alcohol use, for prevention, reduction or treatment. Among the 19 treatment studies with an alcohol and other drug use outcome, there was a trend for promising short-term effect but with limited information about intervention fidelity and exercise dose, there was a moderate to high risk of bias. We identified no studies reporting the cost-effectiveness of interventions. More rigorous and well-designed research is needed. Our novel approach to the review provides a clearer guide to achieve this in future research questions addressed to inform policy and practice for different populations and settings.

Substance use profile, treatment compliance, treatment outcomes and related factors in probation: a retrospective file review

OBJECTIVE

In this study, we aimed to investigate the sociodemographic characteristics of the individuals who mandated to the probation unit as the substances they use, their compliance with the programs, treatment outcomes and the relationships between these parameters. Secondly we aimed to determine the predictive factors that guide in taking protective measures.

METHODS

The files of the individuals who applied to probation clinic of Gaziantep 25 Aralik State Hospital between 01.01.2019-31.12.2019 were examined retrospectively. SPSS 22.0 program was used to statistical analysis.

RESULTS

Totally 1024 cases were included in the study. Most of the cases were between the ages of 16-35 (84.1%) and 68.3% of individuals were primary school graduates. Most (n: 607, 59.3%) were single in terms of marital status. Substance was detected in the urine of 30.3% of the applicants (n: 311). Among the substances detected in urine, amphetamine-methamphetamine was in the first place with 13.6%. In terms of treatment compliance levels of probation, it was seen that 593 (57.9%) reports were prepared as "no treatment required", 117 (11.4%) were "compliant to treatment" and 303 (29.6%) were "noncompliant to treatment". A statistically significant difference was found between working status and treatment outcomes (p = 0.001). When the first urine result of the patients were grouped as negative and positive; A statistically significant difference was found between the first urine test and the treatment outcomes and criminal score (for both p = 0.001).There was a statistically significant difference between the status of being a probation measure previously and the outcome of treatment (p = 0.019).

CONCLUSION

In our study, the most used substance type was found to be amphetamine-methamphetamine (13.6%). Prevalence in substance use appears to be changing. This is an important finding about the prevalence of use of amphetamine-methamphetamine in Turkey. We suggest that those who have irregular jobs in the probation process, those with substance metabolites detected in the first urine, and those who have previously had probation precautions may have a poor prognosis and that it may be more effective to apply to those profiles in a general program that includes social and occupational fields.

Genera and species vs. laws of nature two epistemic frameworks and their respective ideal worlds

This paper seeks to exhibit and explain, by way of comparison, two ideal kinds of knowledge: knowledge based on classifications according to genera and species, as in Aristotelianism and common sense, and scientific knowledge based on the application of laws of nature. I will proceed by attempting (1) to determine the role that presuppositions play in knowledge in general by means of the distinction between content and form; (2) to describe and explain the main features of both ideal forms of knowledge; and, finally, (3) to analyze the relation between these two forms of knowledge as it is presented in Eddington's celebrated discussion of the "two tables". I will be critical of the widespread view that modern science is the correct form of knowledge, and that common sense is merely an illusion.

The physical and psychological wellbeing of caregivers of individuals suffering from substance addiction

OBJECTIVE

This paper seeks to examine the physical and psychological wellbeing of caregivers of individuals suffering from substance addiction.

METHOD

To obtain knowledge of the needs of caregivers of substance addicted individuals and investigating their wellbeing, this paper presents a systematic literature review. Both electronic and manual searches were done on EBSCO host, eBooks collection, Academic search complete, CINAHL Plus, Health source (academic, nursing and consumer edition), Medline, Masterfile, PsycARTICLES and Google Scholar. Books relevant to the topic searched were also used.

RESULTS

The results gave an overview of needs and wellbeing issues concerning the caregivers of individuals suffering from substance addiction and what can be implemented to address their wellbeing such as confidence, maintenance of relationships, engaging with the world, being productive and coping with stress.

CONCLUSIONS

This review indicated that future research should aim to ensure the psychological and physical wellbeing of caregivers of individuals addicted to substances as these individuals' experiences and perspectives are almost always neglected. Avenues for avoidance and early intervention of deterioration of wellbeing of these individuals should be explored.

Evaluation of selective outcome reporting and trial registration practices among addiction clinical trials

BACKGROUND AND AIMS

Selective outcome reporting occurs when trialists pre-specify primary and secondary outcomes during trial planning but alter the definitions in the published report. Here, we investigate selective outcome reporting in published addiction randomized controlled trials (RCTs) and evaluate whether particular funding sources are associated with an increased likelihood of selective outcome reporting.

DESIGN

We conducted a cross-sectional study of published addiction clinical trials. A PubMed search was performed to identify RCTs in addiction journals from 2013 to 2017. Included studies used a randomized design to address one of the following topics: (1) drug, alcohol and tobacco addiction prevention, (2) stabilization following excessive use of a substance, (3) relapse prevention or (4) recovery maintenance.

SETTING

Single-center, medical research institution.

PARTICIPANTS

Our sample included 162 RCTs that were prospectively registered with a clearly defined primary outcome.

MEASUREMENT

We extracted the following items from addiction RCTs: journal, funding source, trial registry number (if included), sample size, dates of subject enrollment, whether primary and secondary outcomes were denoted, all published outcomes, P-value for all outcomes and whether authors mentioned any deviations from the trial protocol as it related to RCT outcomes.

FINDINGS

In total, 47 of 162 RCTs (29.0%) had at least one major discrepancy between the trial registry and published RCT. Overall, these 47 RCTs included 54 major discrepancies. The most common major discrepancy was demotion of a primary registered outcome (19/54, 35.2%). The majority of RCTs (132/162, 81.5%) were funded from public sources. Additionally, 166 RCTs were excluded from our sample because registration could not be confirmed.

CONCLUSIONS

There is evidence suggestive of selective outcome reporting in addiction randomized controlled trials (RCTs). The most common major discrepancies pertained to the primary outcome.

A Latent Class Analysis of Parental Alcohol and Drug Use: Findings from the Avon Longitudinal Study of Parents and Children

•

We identified four parental substance use classes using quantity-frequency measures.

•

Heavy use of alcohol formed a class which also included a large proportion of drug users.

•

Mothers’ and their partner’s tended to have similar patterns of substance use behaviours.

Previous measures of parental substance use have often paid limited attention to the co-occurrence of alcohol and drugs, or to the between-parent dynamics in the use of substances. These shortcomings may have important implications for our understandings of the relationship between parental substance use and child wellbeing. Using data from the Avon Longitudinal Study of Parents and Children, a UK community-based cohort study from 1990 onwards (n = 9,451), we identified groups of parental substance use using latent class analysis. The 4-class solution offered the best fit, balancing statistical criteria and theoretical judgement. The results show distinct classes across the range of parental substance use, including very low users, low users, moderate users and heavy users. These classes suggest that substance use patterns among mothers are somewhat mirrored by those of their partners, while heavy use of alcohol by mothers and their partners is related to increased mothers drug use. We suggest that studies that investigate the effects of parental substance use on child wellbeing should pay greater attention to the dynamics of substance use by parental figures.

Prevalence and associated predictors for patients developing chronic neuropathic pain following burns

BACKGROUND

Chronic pain, unrelated to the burn itself, can manifest as a long-term complication in patients sustaining burn injuries. The purpose of this study was to determine the prevalence of chronic neuropathic pain (CNP) and compare burn characteristics between patients who developed CNP and patients without CNP who were treated at a burn center.

METHODS

A single-center, retrospective analysis of 1880 patients admitted to the adult burn center was performed from 1 January 2014 to 1 January 2019. Patients included were over the age of 15 years, sustained a burn injury and were admitted to the burn center. CNP was diagnosed clinically following burn injury. Patients were excluded from the definition of CNP if their pain was due to an underlying illness or medication. Comparisons between patients admitted to the burn center with no pain and patients admitted to the burn center who developed CNP were performed.

RESULTS

One hundred and thirteen of the 1880 burn patients developed CNP as a direct result of burn injury over 5 years with a prevalence of 6.01%. Patients who developed CNP were a significantly older median age (54 years vs. 46 years, p = 0.002), abused alcohol (29% vs. 8%, p < 0.001),abused substances (31% vs. 9%, p < 0.001), were current daily smokers (73% vs. 33%, p < 0.001), suffered more full-thickness burns (58% vs. 43%, p < 0.001), greater median percent of total body surface area (%TBSA) burns (6 vs. 3.5, p < 0.001), were more often intubated on mechanical ventilation (33% vs. 14%, p < 0.001), greater median number of surgeries (2 vs. 0, p < 0.001) and longer median hospital length of stay (LOS) (10 days vs. 3 days, p < 0.001), compared to those who did not develop CNP, respectively. Median patient follow-up was 27 months.

CONCLUSIONS

The prevalence of CNP over 5 years was 6.01% in the burn center. Older ages, alcohol abuse, substance abuse, current daily smoking, greater percent of total body surface area (%TBSA) burns, third degree burns, being intubated on mechanical ventilation, having more surgeries and longer hospital LOS were associated with developing CNP following burn injury, compared to patients who did not develop CNP following burn injury.

Perceived discrimination in addiction recovery: Assessing the prevalence, nature, and correlates using a novel measure in a U.S. National sample

BACKGROUND

Alcohol and other drug (AOD) problems are among the most stigmatized conditions globally diminishing help-seeking due to fear of discrimination. Discrimination is common also among people already in AOD recovery, but little is known about the prevalence and nature of perceived discrimination. Greater knowledge would inform treatment and policy.

METHOD

Nationally representative cross-sectional sample of U.S. adults who reported resolving an AOD problem (final weighted sample n = 2002). Participants were asked, "Since resolving your problem with alcohol or drugs, how frequently have the following occurred because someone knew about your alcohol or drug history?".

MEASURES

Item response models yielded two types of discrimination: 1. Micro discrimination (personal slights) 2. Macro discrimination (violations of personal rights); psychological distress, quality of life, and recovery capital.

RESULTS

About one quarter of participants reported some type of micro discrimination (e.g., held to a higher standard) with slightly less reporting a violation of personal rights (e.g., couldn't get a job). After adjusting for addiction severity and years since problem resolution, greater micro and macro discrimination were associated with higher psychological distress (β = .45, 95% CI = .35,.55 and β = .59, 95% CI = .45,.73), lower quality of life (β =-.41, 95% CI=-.57,-.26 and β =-.49, 95% CI=-.76,-.21) and recovery capital (β =-.33, 95% CI=-.54,-.12 and β =-.68, 95% CI=-.97,-.40) respectively.

CONCLUSIONS

Despite being in recovery, different types of discrimination are experienced. These are associated with increased distress, and lower quality of life and recovery capital. Prospective studies are needed to help clarify the exact nature and impact of such discrimination on AOD problem recurrence.

Dynamic Systems, Process and Development

In this article, I answer the questions from Witherington and Boom's introduction to this special issue in the form of an imaginary interview, led by David Boom, equally imaginary editor of The Processual Inquirer, an obscure but interesting journal that appears in imaginary physical print only, and which, as a consequence, has so far left no traces on the Internet….

A state-level study of opioid use disorder treatment access and neonatal abstinence syndrome

Background

Adult opioid use and neonatal abstinence syndrome (NAS) are growing public health problems in the United States (U.S.). Our objective was to determine how opioid use disorder treatment access impacts the relationship between adult opioid use and NAS.

Methods

We conducted a cross-sectional state-level ecologic study using 36 states with available Healthcare Cost and Utilization Project State Inpatient Databases in 2014. Opioid use disorder treatment access was determined by the: 1) proportion of people needing but not receiving substance use treatment, 2) density of buprenorphine-waivered physicians, and 3) proportion of individuals in outpatient treatment programs (OTPs). The incidence of NAS was defined as ICD-9 code 779.5 (drug withdrawal syndrome in newborn) from any discharge diagnosis field per 1000 live births in that state.

Results

Unmet need for substance use disorder treatment correlated with NAS (r = 0.54, 95% CI: 0.26–0.73). The correlation between adult illicit drug use/dependence and NAS was higher in states with a lower density of buprenorphine-waivered physicians and individuals in OTPs.

Conclusions

Measures of opioid use disorder treatment access dampened the correlation between illicit drug use/dependence and NAS. Future studies using community- or individual-level data may be better poised to answer the question of whether or not opioid use disorder treatment access improves NAS relative to adult opioid use.

An Investigation of the Impact of Childhood Trauma on Quality of Caregiving in High Risk Mothers: Does Maternal Substance Misuse Confer Additional Risk?

The quality of caregiving is often compromised when mothers have co-occurring difficulties such as substance misuse and problems associated with extreme emotional dysregulation. These, in turn, are associated with poor child outcomes. The aim of the current study was twofold. First, to investigate the potential differences in risk factors associated with poor child outcome by comparing three groups: substance misusing mothers (Substance Misusing Mothers; SMM); mothers matched on demographic characteristics (Matched Comparison Mothers; MCM) and mothers recruited from the community (Matched Control Comparison; MCC). Second, to investigate the underlying mechanisms which are associated with poor child outcome by testing a mediated moderation model to ascertain (i) whether environmental risk and borderline psychopathology was a mediator between maternal childhood trauma and quality of caregiving and (ii) maternal substance misuse status moderated outcome. There were no significant differences found between the SMM and MCM groups on the key variables, but significant differences on all variables for both SMM and MCM compared to CCM. The moderated mediation analysis found that while there was significant mediation of environmental risk and borderline pathology between maternal childhood trauma and child outcome, this was not moderated by maternal substance abuse status. The importance of environmental-risk as a mechanism leading to reduced caregiving quality suggest treatment programs need to consider targeting these factors in high risk families.

"Five-year changes in population newborn health associated with new preventive services in targeted risk-group pregnancies"

Backgrounds

In 2009, the prevention service “Familieambulatoriet” (FA) was established in three pilot hospital areas offering psychosocial support and health monitoring to parents in high risk regarding mental health and substance use, for the purpose of preventing child mental health and developmental problems through preschool years. This study selected new-born health as a preliminary endpoint for evaluation of population effects in three pilot areas, utilizing national statistics for birth cohorts from 2005 to 2013. The aim of the study is to evaluate changes in population new born health incidences associated with the establishment of new supportive and preventive FA-services at three pilot sites from 2009 in contrast to previous years and the remaining country. This quasi-experimental design evaluated changes in populations with new services available not those receiving the services, and controlled for national historical changes, variation between hospital districts, and random variation across the years before or years after the pilot services were introduced. Our hypothesis was to expect reduced frequencies of preterm births, SGA births, low APGAR scores, pediatric transfer, and new born abstinence symptoms in the pilot areas.

Methods

The baseline was established through 4 years preceding 2009, contrasting changes at pilot sites the following 4 years 2009–2013 using the remaining hospital area populations in Norway 2005–2008 and 2009–2013 as contrasts.

Results

Related to the introduction of FA services, we found three significant improvements in new born health using mixed effects logistic regression. 1) In the population rate of babies born prematurely with small for gestational age (SGA), using the 10th percentile criteria as the definition; odds ratio (OR) = 0.73 (95% Cl: 0.60 to 0.88). 2) A similar reduction using the 2.5th percentile criteria, although with wider confidence limits; OR = 0.73 (95% Cl: 0.54 to 0.99). 3) A decrease in the frequency of low APGAR scores (0–6) 5 min. after birth; OR = 0.80 (95% Cl: 0.68 to 0.95). Thus, the FA-areas remained significantly lowered on SGA rates or Low APGAR rates across the years after FA establishment, despite considerable variation, in contrast to the baseline years and to the remaining country. No significant effect was found for the outcomes frequency of premature births (unrelated to SGA), SGA among full-term babies, child abstinence symptoms or pediatric transfer of the baby. False negative findings may result from low-rate outcomes or studying the population rather than users.

Conclusions

Population rates suggest that introducing FA services offering support and monitoring in high-risk families may contribute to improving aspects of new born infant health. Intervention components and strategies should be studied more closely using individual data.

Feasibility and acceptability of integrated psychological therapy versus treatment as usual for people with bipolar disorder and co-morbid alcohol use: A single blind randomised controlled trial

BACKGROUND

Alcohol use is a common problem in bipolar disorder (BD) and evidence indicates more promising outcomes for alcohol use than other substances. No trials have evaluated individual integrated motivational interviewing and cognitive behaviour therapy (MI-CBT) for problematic alcohol use in BD. We therefore assessed the feasibility and acceptability of a novel MI-CBT intervention for alcohol use in BD.

METHODS

A single blind RCT was conducted to compare MI-CBT plus treatment as usual (TAU) with TAU only. MI-CBT was delivered over 20 sessions with participants followed up at 3, 6, 9 and 12 months post-randomisation. Primary outcomes were the feasibility and acceptability of MI-CBT (recruitment to target, retention to follow-up and therapy, acceptability of therapy and absence of adverse events). We also conducted preliminary analyses of alcohol and mood outcomes (frequency and severity of alcohol use and time to mood relapse).

RESULTS

44 participants were recruited with 75% retention to 6 and 12 months follow-up. Therapy participants attended a mean of 17.6 (SD 4.5) sessions. Therapy alliance and treatment fidelity were acceptable. Qualitative interviews indicated the intervention was experienced as collaborative, and helpful, in addressing mood and alcohol issues, although risk of overconfidence following therapy was also identified. Clinical outcomes did not differ between arms at 12 months follow-up.

LIMITATIONS

As a feasibility and acceptability trial any secondary results should be treated with caution.

CONCLUSIONS

Integrated MI-CBT is feasible and acceptable, but lack of clinical impact, albeit in a feasibility study, suggests need for further development. Potential adaptations are discussed.

Insomnia severity during early abstinence is related to substance use treatment completion in adults enrolled in an intensive outpatient program

BACKGROUND

Insomnia and other types of sleep disturbance are highly prevalent during withdrawal across many different types of substance use disorders (SUDs). It is largely unknown how sleep impacts SUD treatment outcomes, including treatment completion.

METHODS

A retrospective chart review was conducted to obtain information about sleep disturbance and treatment completion in individuals beginning an intensive outpatient (IOP) SUD treatment program. Demographic data were collected along with number of sessions completed, treatment completion, comorbid psychiatric diagnosis, pertinent lab results, and scores on three self-reported measures of sleep: the Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS).

RESULTS

Pertinent information was available for 110 individuals. The majority had clinically significant scores on the ISI and PSQI but not the ESS. ISI, but not PSQI or ESS, was associated with treatment completion, such that those with more insomnia were less likely to complete treatment.

CONCLUSION

The high prevalence of insomnia symptoms and poor sleep quality coupled with the relationship between insomnia severity and treatment completion may indicate that more severe symptoms of insomnia are a risk factor for treatment completion and subsequent relapse across many substance types. Applying evidence-based insomnia interventions in SUD treatment programs may have meaningful implications for outcomes.

Fundamental Characteristics, Attitudes and Behaviors Regarding Substance Use Focusing on Cannabis: Findings from the General Population Survey in Turkey, 2011

Cannabis is the most prevalent illicit drug used in the world. We aimed to determine prevalence and some characteristics of cannabis use in Turkey. The study was based on a cross-sectional survey conducted with a nationally representative sample of 8045 individuals with in-house interviews. The life-time prevalence of substance use was found as 2.8%. Cannabis with 0.7% life-time prevalence, was the most commonly used substance. Cannabis users were concerned about some adverse outcomes such as anxiety with withdrawal (14%), losing control about using the drug (14%), daily performance problems (10.9%) and problems about interpersonal violence (6.9%). 35.1% of them wanted to quit and 18% regretted using cannabis. Prevalence of cannabis use is lower in Turkey compared with most of the other countries in the world. Nevertheless, it is a significant health concern. Identifying characteristics and attitudes related with cannabis use may help to improve policies about protective measures.

Abuse and Effects of Salvia divinorum in a Sample of Patients Hospitalized for Substance Dependence

The study goal is to document the prevalence of salvia use among patients admitted for detoxification of other illicit drug use and to determine its effect. This cross-sectional study included 47 heavy drug users who were admitted for detoxification of other illicit drug abuse at a psychiatric hospital in Lebanon. The prevalence of salvia use was 66%. The salvia effect started and dissipated rapidly (15 min). No significant difference was found between salvia and non-salvia users in terms of affect, cognition and somaesthesia subscales of the Hallucinogen Rating Scale. Ratings of intensity and volition subscales were higher in non-salvia users than salvia users, while perception score was higher in users. Salvia use was correlated with perceptual alteration and hallucinogenic effects.

CuDDI: A CUDA-Based Application for Extracting Drug-Drug Interaction Related Substance Terms from PubMed Literature

Drug-drug interaction (DDI) is becoming a serious issue in clinical pharmacy as the use of multiple medications is more common. The PubMed database is one of the biggest literature resources for DDI studies. It contains over 150,000 journal articles related to DDI and is still expanding at a rapid pace. The extraction of DDI-related information, including compounds and proteins from PubMed, is an essential step for DDI research. In this paper, we introduce a tool, CuDDI (compute unified device architecture-based DDI searching), for identification of DDI-related terms (including compounds and proteins) from PubMed. There are three modules in this application, including the automatic retrieval of substances from PubMed, the identification of DDI-related terms, and the display of relationship of DDI-related terms. For DDI term identification, a speedup of 30–105 times was observed for the compute unified device architecture (CUDA)-based version compared with the implementation with a CPU-based Python version. CuDDI can be used to discover DDI-related terms and relationships of these terms, which has the potential to help clinicians and pharmacists better understand the mechanism of DDIs.

Substance use among treatment seeking Indian adolescent girls: Are they unique?

INTRODUCTION

Substance use among adolescents is on the rise across the globe along with a diminution of gender gap observed earlier posing a huge public health burden. Unfortunately, there is a paucity of literature on adolescent substance use. The literature is even sparse about substance use among adolescent girls. The current study aims to provide a glimpse of the profile and pattern of substance use among Indian adolescent girls seeking treatment for substance use problems in a specialty addiction treatment centre in India.

MATERIALS AND METHODS

This study is retrospective in design. Information regarding socio-demographics and substance use were extracted from the medical records of adolescent girls (≤ 19 years) who sought treatment for substance use problems during 2004-2018, at the adolescent clinic of a tertiary addiction treatment centre located in north India was retrieved carried out. The data was statistically analysed using SPSS.

RESULTS

A total of 28 girls sought treatment during this period. The mean age of the girls was 15.89 ± 2.72 years. Most of the girls were students (6/28) or had never started working (12/28). Majority of them were coming from an urban background (89.3%) and were educated up to 10^th class (85.5%). A total of 17 (60.7%) girls sought treatment for opioids use of which 11 were using illicit opioids like heroin and five (29.9%) of them reported taking opioids by injecting route primarily. History of past abstinence attempts, and treatment attempt were present in very few of them (10.7% and 14.3%).

CONCLUSION

Our study suggests a distinct substance use profile of adolescent girls. There is a need for further systematic studies to assess their clinical needs.

#digital hood: Engagement with Risk Content on Social Media among Black and Hispanic Youth

The digital neighborhood is the amalgamation of the spaces online where youth connect with others. Just as Black and Hispanic youth live in neighborhoods that influence their health, they are also influenced by online digital neighborhoods. Youth are exposed to social media content featuring substance use, sexual risk, and violence, yet little is known about the extent to which youth engage with such content. Using a modified venue sampling strategy, we administered CASI surveys to 145 Black and Hispanic youth aged 13-24 living in low-income urban neighborhoods. Across social media platforms, respondents reported high levels of exposure to sexual, alcohol, drug, and violence-related content (65-84%). Users reported lower levels of engagement with risk-related content (on an engagement continuum), ranging from passive exposure to dissemination. While negative risks may be amplified in the digital neighborhood, youth appear to strategically limit their engagement with that content. However, because risk behavior messaging is common in these digital neighborhoods, these spaces provide opportunities for health promotion interventions.

Leveraging calcium imaging to illuminate circuit dysfunction in addiction

Alcohol and drug use can dysregulate neural circuit function to produce a wide range of neuropsychiatric disorders, including addiction. To understand the neural circuit computations that mediate behavior, and how substances of abuse may transform them, we must first be able to observe the activity of circuits. While many techniques have been utilized to measure activity in specific brain regions, these regions are made up of heterogeneous sub-populations, and assessing activity from neuronal populations of interest has been an ongoing challenge. To fully understand how neural circuits mediate addiction-related behavior, we must be able to reveal the cellular granularity within brain regions and circuits by overlaying functional information with the genetic and anatomical identity of the cells involved. The development of genetically encoded calcium indicators, which can be targeted to populations of interest, allows for in vivo visualization of calcium dynamics, a proxy for neuronal activity, thus providing an avenue for real-time assessment of activity in genetically and anatomically defined populations during behavior. Here, we highlight recent advances in calcium imaging technology, compare the current technology with other state-of-the-art approaches for in vivo monitoring of neural activity, and discuss the strengths, limitations, and practical concerns for observing neural circuit activity in preclinical addiction models.
