The destructive capacity of drug abuse: an overview exploring the harmful potential of drug abuse both to the individual and to society

Neck Abscess Due to Pocket Shot: Is It Just the Tip of the Iceberg?

A 45-year-old Caucasian male presented to the emergency department for pain and swelling on the left side of his neck for the past 10 days. His medical history revealed that he was an intravenous (IV) drug abuser. Physical examination demonstrated a 5×5 cm red, swollen bump with a positive fluctuation on the left supraclavicular area concerning for an abscess. Fluid aspiration from the abscess was performed, and three sets of blood cultures were obtained, which later all came back positive for methicillin-resistant Staphylococcus aureus (MRSA). His initial blood tests revealed elevated levels of platelets, leukocytes, and C-reactive protein (CRP) and anemia. The computed tomography (CT) scan showed an enlarged pectoralis major with the presence of air. The retrosternal, infraclavicular, and supraclavicular regions also contained air. The clinical diagnosis was therefore supported by the laboratory results and imaging. Additionally, transthoracic echocardiography showed no vegetations, and transesophageal echocardiography was scheduled. Antibacterial treatment was initiated empirically from the emergency room with meropenem and vancomycin, planned for four weeks. Repeat cultures were obtained for the following three days, which were all negative. However, the patient left the hospital against medical advice and did not complete his antibiotic treatment. The risk of a peripherally inserted central catheter (PICC) line being misused for illegal narcotics was considered too high; hence, it was not recommended for continued IV antibiotic therapy at home. Those with a history of intravenous drug use, after using the most accessible injection sites, oftentimes resort to finding alternative and potentially more dangerous injection sites. The major veins of the neck, such as the jugular, subclavian, or brachiocephalic veins, are commonly used. This technique is referred to as a "pocket shot" by intravenous drug abusers (IVDAs). Apart from the apparent abscess, clinicians should oversee for other complications including underlying pus collections, pneumothorax, mediastinitis, osteomyelitis, and hemothorax.

Post-Traumatic Growth and Quality of Life among World Trade Center Health Registry Enrollees 16 Years after 9/11

A recent study of World Trade Center Health Registry enrollees found that about one-third experienced post-traumatic growth (PTG) in the wake of the 9/11 attacks and that PTG was associated with social support and social integration. However, the implications of PTG for the enrollees' overall quality of life are unknown. The present study investigated the prevalence of PTG and its association with the SF-12 physical and mental functioning quality of life scales in a sample of 4760 enrollees from the Registry's Health and Quality of Life Study (HQoL) who completed the first four surveys, were older than 18 on 9/11, reported English as their primary spoken language, and provided consistent self-report of 9/11 physical injury at the Registry's baseline and HQoL surveys. We employed multivariable linear regression to evaluate the association between PTG and the SF-12 physical and mental scales, controlling for sociodemographic and other variables. We found that 31% of the sample enrollees experienced PTG and that PTG exhibited a clinically and statistically significant association with the SF-12 mental scale but not the physical scale (physical: b = 0.15 (-0.45, 0.75), mental: b = 3.61 (2.85, 4.37)). Those who were physically injured during 9/11 showed larger improvements in mental functioning than those who were not. PTG has implications for the overall mental quality of life that should be further investigated.

The SEEKING Drive and Its Fixation: A Neuro-Psycho-Evolutionary Approach to the Pathology of Addiction

Neuro-ethological studies conducted by Panksepp and his colleagues have provided an understanding of how the activity of the mesolimbic dopaminergic (ML DA) system leads to the emotional disposition to SEEK/Explore, which is involved in all appetitive motivated behavior and mental activity. In pathological addiction phenomena, this emotional disposition “fixes” itself on certain obsessive-compulsive habits, losing its versatility and its natural predisposition to spontaneous and unconditioned activation. Overall, the result is a consistent disinterest in everything that is not the object of addiction. From a neuro-psycho-evolutionary point of view, the predisposition to develop addictive behavior can be attributed to a loss of “functional autonomy” of the SEEKING/Explorative disposition. Indeed, as shown by animal and human studies, the tendency to be conditioned by situations and contexts that provide an immediate reward can be closely related to a deficit in the tonic endogenous activity of the ML DA-SEEKING system.

Exploring substance use disorders and relapse in Mauritian male addicts

Background

Substance Use Disorder (SUD) places a heavy burden on societal and health systems given its association with high mortality and morbidity rates worldwide, including Mauritius. Illicit substances act as a positive reinforcement and stimulate addiction through its pleasure-seeking attributes.

Aim

This study focused on identifying the risk factors leading to SUD among Mauritian male addicts as well as examining the potency of those factors in SUD development. The study also aimed at determining the prevalence of relapse and its causation.

Research setting

A cross-sectional study was conducted over a period of six months using a sample of 180 male addicts registered in a public hospital. A questionnaire investigating dimensions such as risk factors, self-esteem and peer pressure was administered.

Findings

A high percentage of relapse was noted amongst users within the first year of abstinence. Majority of respondents originated from nuclear or single parents’ family and were deprived of adequate social supports given their marital status. 57.5% of participants had a positive family history of SUD. Cannabis was the most commonly abused substance and 76.2% of the addicts were introduced to drugs through curiosity. Transposing the results against the Gateway Drug Theory showed a constant progression from soft to hard drugs for male addicts, a trend which was consistent with literature. Lastly, a theoretical model was developed based on the strong statistical association found between impulsivity and reduced thought processes prior to relapse; data revealing increased impulsivity which is a common trait in antisocial personality disorder and borderline personality disorder as being largely responsible for relapse.

Conclusion

The study was successful in bringing out the most common risk factors of SUDs which are linked to low socioeconomic status. The inability of addicts to progress with their rehabilitation given the alarming 92% of relapse was related to social pressure as prime deterrent to successful remission. Programmes involving relapse prevention must implemented in the first year of abstinence to facilitate rehabilitation.

Koori voices: self-harm, suicide attempts, arrests and substance use among Aboriginal and Torres Strait Islander adolescents following residential treatment

BACKGROUND

Complex interacting social, economic and historical factors influence the availability and uptake of alcohol and drugs, including among Indigenous communities. Self-harm and suicide as well as homelessness and incarceration, can both precede and result from drug and alcohol use. Rates of self-harm, suicide and incarceration among Aboriginal and Torres Strait Islander people in Australia are among the highest in the world and drug and alcohol treatment programs need to address these underlying complexities. This study examines whether an 'holistic' residential drug and alcohol treatment program for adolescents, with over 30% of clients identifying as Aboriginal and Torres Strait Islander, can improve outcomes post-discharge, including reducing self-harm, suicide attempts, arrests and alcohol and drug use. The program addresses substance use, mental health, employment, accommodation, social/community and family life. Program admission and 3 months' post-discharge data from 2007 to 2016 were analysed.

RESULTS

From 2007 to 2016, 619 Aboriginal and Torres Strait Islander young people were admitted to the program; 247 stayed in the program for 30 days or more; 89 were successfully followed up three months post-discharge to determine whether there was a significant improvement from baseline using the McNemar's Test and the Wilcoxon Signed Ranks Test. On admission, 18 people (20%) of the study population reported attempting suicide in the last 3 months and 23 people (30%) reported self-harm. Most had been engaged in the criminal justice system, with 67 people (75%) having been to court and 62 people (70%) arrested one or more times in the past 3 months, with 35 people (41%) in unstable housing, reporting having lived in three or more places in the previous 6 months. At 3 months post-treatment, all (n = 18) who reported suicide attempts in the 3 months prior to admission reported no attempts in the prior 3 months at follow-up. There was also a significant reduction in self-harm with 23 young people out of the 27 who reported self-harm at baseline not reporting self-harm at follow up (85%) and in the proportion of adolescents who reported using cannabis, amphetamines and alcohol, as well as a reduction in the proportion who reported being arrested.

CONCLUSIONS

The findings provide support for an 'holistic' residential treatment program as an approach to improve health and related outcomes for Aboriginal and Torres Strait Islander young people. In addition to a focus on multiple aspects of a young person's life in treatment, culturally relevant modes of treatment and support should be a future focus to further strengthen programs when Aboriginal and Torres Strait Islander young people are over-represented in the client group.

Drug use among Teenagers and Young Adults in Bhutan

BACKGROUND

Use, possession, and illegal transactions of controlled substances have increased in recent years in Bhutan. This study aimed to determine the national prevalence of ever drug use and identify its associated factors amongst teenagers and young adults.

METHODS

This study was conducted using data from the National Health Survey 2012 of Bhutan. The outcome variable of interest was ever drug use in teenagers and young adults. The questionnaire was developed following the WHO STEPwise approach to surveillance of non-communicable diseases (STEP). Univariate and multivariate logistic regression were performed to identify correlates of ever drug use.

RESULTS

The prevalence of ever drug use among teenagers and young adults was 3.2% (n = 672). The factors associated with ever drug use were: being men; being single; being in age group of 18-24 years; having a primary school, high school, monastic, university, or diploma education; being technicians or salespersons; feeling always lonely; having ever consumed alcohol, and having ever smoked.

CONCLUSION

Compared to the other countries in the WHO South-east Asia region, the prevalence of ever drug use in Bhutan is low. Use of other substances, including smoking and alcohol use, was associated with ever drug use. For greater effect, drug use prevention strategies should include prevention of smoking and alcohol use.

Early life adversity potentiates expression of addiction-related traits

Many individuals sporadically and circumstantially sample addictive drugs, yet few become addicted. The individual vulnerabilities underlying the development of addiction are not well understood. Correlational findings show that early life adversity is associated with a greater propensity to develop drug addiction. However, the mechanisms by which early life adversity increases addiction vulnerability are unknown. Separate lines of research have found that several traits are associated with addiction. Here, we examined the effects of early life adversity on addiction-related traits in adulthood. We weaned male and female Sprague-Dawley rats (postnatal day - PND21) and randomly assigned them to either a non-adversity group (N-ADV) or an adversity group (ADV). ADV rats experienced adversity from PND 21-35, they were: a) singly housed, b) food restricted for 12h/day, c) subjected to forced-swim sessions, and d) restrained and exposed to predator odour (1h). As adults, rats were tested for impulsivity, anxiety-like behaviour, novelty preference, and attribution of incentive salience to a reward cue. ADV rats showed enhanced novelty preference and attributed greater incentive value to a reward cue. Compared to N-ADV rats, a greater proportion of ADV rats expressed multiple addiction risk traits. Furthermore, fewer ADV rats expressed no addiction risk traits. This effect was most evident in female ADV rats.

Utilization of outpatient medical care and substance use among rural stimulant users: Do the number of visits matter?

Rural substance users are less likely than their urban peers to use formal substance use treatment. It is therefore important to understand how the utilization of potentially more appealing care options, such as outpatient medical care (OMC), may affect substance use over time. This study sought to examine whether the number of OMC visits, after controlling for important covariates, was associated with days of alcohol, crack and powder cocaine, and methamphetamine use among a sample of rural stimulant users over a three year period. Data were collected from a natural history study of 710 stimulant users living in rural communities in Arkansas, Kentucky, and Ohio. Participants were adults, not in drug treatment, and reporting stimulant use in the last 30days. In terms of alcohol use, for participants with higher employment-related problems, having 3 or more OMC visits (relative to none) was associated with fewer days of alcohol use. The results for days of cocaine and methamphetamine use were mixed. However, we did find that for participants reporting at least one substance use treatment or mutual help care visit in the past 6-months, having 1-2 OMC visits (compared to none) was associated with fewer days of crack cocaine use. Regarding methamphetamine use, results showed that for participants without medical insurance, having 3 or more OMC visits (compared to none) was associated with significantly fewer days of methamphetamine use if they also reported greater than or equal to a high school education. The findings from this study may help us begin to understand some of the characteristics of rural drug users, who utilize OMCs, associated with reductions in substance use. These findings may help health care administrators better plan, coordinate, and allocate resources to rural OMCs to more effectively address substance use in this population.

Refining Measurement of Substance Use Disorders Among Women of Child-Bearing Age Using Hospital Records: The Development of the Explicit-Mention Substance Abuse Need for Treatment in Women (EMSANT-W) Algorithm

Substance use disorder (SUD) in women of reproductive age is associated with adverse health consequences for both women and their offspring. US states need a feasible population-based, case-identification tool to generate better approximations of SUD prevalence, treatment use, and treatment outcomes among women. This article presents the development of the Explicit Mention Substance Abuse Need for Treatment in Women (EMSANT-W), a gender-tailored tool based upon existing International Classification of Diseases, 9th Edition, Clinical Modification diagnostic code-based groupers that can be applied to hospital administrative data. Gender-tailoring entailed the addition of codes related to infants, pregnancy, and prescription drug abuse, as well as the creation of inclusion/exclusion rules based on other conditions present in the diagnostic record. Among 1,728,027 women and associated infants who accessed hospital care from January 1, 2002 to December 31, 2008 in Massachusetts, EMSANT-W identified 103,059 women with probable SUD. EMSANT-W identified 4,116 women who were not identified by the widely used Clinical Classifications Software for Mental Health and Substance Abuse (CCS-MHSA) and did not capture 853 women identified by CCS-MHSA. Content and approach innovations in EMSANT-W address potential limitations of the Clinical Classifications Software, and create a methodologically sound, gender-tailored and feasible population-based tool for identifying women of reproductive age in need of further evaluation for SUD treatment. Rapid changes in health care service infrastructure, delivery systems and policies require tools such as the EMSANT-W that provide more precise identification methods for sub-populations and can serve as the foundation for analyses of treatment use and outcomes.

Treatment outcomes for substance use disorder among women of reproductive age in Massachusetts: a population-based approach

INTRODUCTION

Longitudinal patterns of treatment utilization and relapse among women of reproductive age with substance use disorder (SUD) are not well known. In this statewide report spanning seven years we describe SUD prevalence, SUD treatment utilization, and differences in subsequent emergency department (ED) use and post-treatment relapse rates by type of treatment: none, 'acute only' (detoxification/stabilization), or 'ongoing' services.

METHODS

We linked a statewide dataset of hospital discharge, observation stay and ED records with SUD treatment admission records from hospitals and freestanding facilities, and birth/fetal death certificates, in Massachusetts, 2002-2008. We aggregated episodes into individual woman records, identified evidence of SUD and treatment, and tested post-treatment outcomes.

RESULTS

Nearly 150,000 (8.5%) of 1.7 million Massachusetts women aged 15-49 were identified as SUD-positive. Nearly half of SUD-positive women (71,533 or 48.3%) had evidence of hospital or facility-based SUD treatment; among these, 12% received acute care/detoxification only while 88% obtained 'ongoing' treatment. Treatment varied by substance type; women with dual diagnosis and those with opiate use were least likely to receive 'ongoing' treatment. Treated women were older and less likely to have a psychiatric history or chronic illness. Women who received 'acute only' services were more likely to relapse (12.4% vs. 9.6%) and had a 10% higher rate of ED visits post-treatment than women receiving 'ongoing' treatment.

CONCLUSIONS

Many Massachusetts women of reproductive age need but do not receive adequate SUD treatment. 'Ongoing' services beyond detoxification/stabilization may reduce the likelihood of post-treatment relapse and/or reliance on the ED for subsequent medical care.
