Reevaluating ADHD and its First-Line Treatment: Insights from DSM-5-TR and Modern Approaches.

Is Attention Deficit Hyperactivity Disorder (ADHD) a "brain disorder"? Should it be managed regularly with stimulant drugs? This article critically examines the evolving biomedical discourse surrounding these questions through a close inspection of the latest edition of the influential psychiatric manual - the DSM-5-TR - as well as additional authoritative sources (e.g., previous DSM editions, consensus statements, FDA communications). The DSM-5-TR acknowledges that "no biological marker is diagnostic for ADHD" and that "meta-analyses of all neuroimaging studies do not show differences between individuals with ADHD and control subjects." The authors of the DSM-5-TR, therefore, conclude that "until these issues are resolved, no form of neuroimaging can be used for diagnosis of ADHD." These statements, along with biases in the neuroimaging literature and additional empirical evidence presented in the article, challenge popular myths about the neurobiological basis of ADHD. Similarly, common beliefs about the first-line treatment of ADHD with stimulant drugs are being increasingly questioned today. For instance, the DSM-5-TR's section on Stimulant-Related Disorders introduces a new diagnostic entity named: Stimulant-Induced Mild Neurocognitive Disorder. This addition aligns with a recent FDA Drug Safety Communication for "all prescription stimulants," which highlights longstanding concerns regarding the safety of medications prescribed to millions of diagnosed individuals, primarily children. The FDA now mandates that "the Boxed Warning, FDA's most prominent warning, will describe the risks of misuse, abuse, addiction, and overdose," emphasizing that such "misuse and abuse of prescription stimulants can result in overdose and death." In light of these challenges to the biomedical discourse, this article offers a neurodiversity-oriented alternative. Using evolutionary principles and historical context, it argues that most cases of ADHD fall under the DSM's socio-philosophical category of "conflicts that are primarily between the individual and society" (similar to homosexuality, which was removed from the DSM in 1973), and are therefore "not mental disorders".

Unraveling how hydrogen-bonding networks affect the capture of amphetamine-type stimulants by polymerized deep eutectic solvent modified magnetic biochar: Coupling quantum chemical calculations with experiment

The abuse of amphetamine-type stimulants (ATSs) has caused irreversible harm to public safety and ecosystems. A novel polymerized deep eutectic solvent modified magnetic pomelo peel biochar (PMBC) was prepared, and the differences in adsorption of four abused amphetamine-type stimulants (ATSs: AMP, MAMP, MDA and MDMA) were due to varying hydrogen bonds quantities and strengths. PMBC showed excellent chemical reactivity to MDMA, with a maximum adsorption capacity of 926.13 μg g−1, which was 3.25, 2.52 and 1.15 times higher than that of AMP, MAMP and MDA, respectively. Modern spectral analysis showed that there were a series of active centers (-COOH, -NH2 and -OH) on the PMBC, which could form hydrogen bond networks with the nitrogen and oxygen functional groups of ATSs. In various chemical environments: pH level (4–11), inorganic ion and organic matter (humic acid), PMBC maintained high activity towards four ATSs. Additionally, the quantum chemical calculations revealed that the methylenedioxy bridge of ATSs can increase the active sites, and the -NH- and -NH2 groups had different hydrogen bond formation capabilities, which together resulted in the adsorption order of PMBC on the four ATSs: MDMA > MDA > MAMP > AMP. Moreover, the hydrogen-bonding binding energies of several common hydrogen-bonding types were compared, including O-H····O, N-H····O/O-H····N and N-H···N. This study laid an empirical and theoretical foundation for the efficient capture of ATSs in water and contributed to the innovative design of materials.

Effects of Dual Inhibition at Dopamine Transporter and σ Receptors in the Discriminative-Stimulus Effects of Cocaine in Male Rats.

Previous studies demonstrated that sigma receptor (σR) antagonists alone fail to alter cocaine self-administration despite blocking various other effects of cocaine. However, σR antagonists when combined with dopamine transporter (DAT) inhibitors substantially decrease cocaine self-administration. To better understand the effects of this combination, the present study examined the effects of σR antagonist and DAT inhibitor combinations in male rats discriminating cocaine (10 mg/kg, i.p.) from saline injections. The DAT inhibitors alone [(-)-2-β-carbomethoxy-3-β-(4-fluorophenyl)tropane 1,5-naphthalenedisulfonate monohydrate (WIN 35,428) and methylphenidate] at low (0.1-mg/kg) doses that were minimally active failed to shift the dose-effect function for discriminative-stimulus effects of cocaine to the left more than 2-fold. At 0.32 mg/kg the DAT inhibitors alone shifted the cocaine dose-effect function leftward 24- or 6.6-fold, respectively. The σR antagonists (BD1008, BD1047, and BD1063) failed to fully substitute for cocaine, although BD1008 and BD1047 substituted partially. At 10 mg/kg, BD1008, BD1047, or BD1063 alone shifted the cocaine dose-effect function leftward less than 6.0-fold. In combination with 0.1 mg/kg WIN 35,428, the 10 mg/kg doses of σR antagonists shifted the cocaine dose-effect function from 12.3- to 36.7-fold leftward, and with 0.32 mg/kg WIN 35,428 from 14.3- to 440-fold leftward. In combination with 0.1 mg/kg methylphenidate, those σR antagonist doses shifted the cocaine dose-effect function from 5.5- to 55.0-fold leftward, and with 0.32 mg/kg methylphenidate from 10.5- to 48.1-fold leftward. The present results suggest that dual DAT/σR inhibition produces agonist-like subjective effects that may promote decreases in self-administration obtained in previous studies. SIGNIFICANCE STATEMENT: There is currently no approved medication for treating stimulant abuse, although dopamine uptake inhibitors in combination with sigma receptor (σR) antagonists decrease cocaine self-administration in laboratory animals. The present study assessed how this combination alters the discriminative-stimulus effects of cocaine in male rats. Results suggest that concurrent dopamine uptake inhibition and σR antagonism together may promote decreases in self-administration, possibly by mimicking the subjective effects extant when subjects cease continued cocaine self-administration.

Changes in Substance Use Diagnoses in the Great Plains during the COVID-19 Pandemic.

As drug overdose mortality rises in the United States, healthcare visits present critical opportunities to mitigate this trend. This study examines changes in healthcare visits for substance use disorders (SUDs) and remission prior to and during the COVID-19 pandemic in the Great Plains, with a focus on identifying the characteristics of those served. Data were analyzed from 109,671 patient visits (mode = one visit per patient), encompassing diverse demographics, including sex, age, race, ethnicity, and geographic location. Visits analyzed included those for Alcohol Use Disorder (AUD), Opioid Use Disorder (OUD), or Stimulant Use Disorder (StUD) and those in remission of these disorders between March 2019 and March 2021. Patient demographic information and geographic factors, like rurality and Medicaid expansion status, were considered, and logistic regression was utilized. Visits were primarily by White (70.83%) and Native American (21.39%) patients, non-Hispanic (91.70%) patients, and males (54.16%). Various demographic, geographic, and temporal trends were observed. Findings indicated that males were more likely to receive an AUD diagnosis, while females were more likely to receive an OUD or StUD diagnosis. Metropolitan-residing patients were more likely to receive an AUD diagnosis, while non-metropolitan patients were more likely to receive an OUD diagnosis. Remission odds increased for StUD during the pandemic but decreased for AUD and OUD. These findings illuminate the demographic and geographic patterns of SUD-related healthcare visits, suggesting critical touchpoints for intervention. The results emphasize the urgent need for targeted healthcare strategies, especially in rural and underserved areas, to address persistent health disparities.

A case of severe opioid and methamphetamine use disorder in a 14 year old

We present the case of a 14-year-old who established care at our primary care clinic after hospitalization for unintentional fentanyl overdose. They were diagnosed with severe opioid use disorder (OUD) and stimulant use disorder (StUD) and initiated buprenorphine while inpatient. They were then transitioned to the only known outpatient primary care clinic in her county who was actively providing medications for opioid use disorder (MOUD) in adolescents.At the first visit, they reported a history of 20 overdoses, struggling with adherence to buprenorphine and continued opioid cravings. An overdose safety plan was reviewed with them and their parent including providing them naloxone kits, fentanyl test strips, and education handout sheets. Due to their significant overdose history and adherence challenges with sublingual buprenorphine, they were started on long-acting injectable buprenorphine (LAIB) with weekly provider visits and urine toxicology screening. In collaboration with the treatment team, they initiated behavioral treatment with contingency management (CM), with incentives for appointment completion, expected urine results, and successful medication administration. Over the next 19 months, and to date, they have increasingly engaged with care and have remained abstinent. LAIB may be an appealing alternative for adolescents with OUD to improve adherence and reduce risk of recurrent use and overdose. Adjunctive treatment with CM may improve retention in MOUD and have the benefit of treating StUD. There is a need for further research to explore innovative, community-based treatment for youth with OUD.

Trends in peripheral artery disease and critical limb ischemia hospitalizations among cocaine and methamphetamine users in the United States: a nationwide study.

Peripheral artery disease (PAD) is on the rise worldwide, ranking as the third leading cause of atherosclerosis-related morbidity; much less is known about its trends in hospitalizations among methamphetamine and cocaine users. We aim to evaluate the overall trend in the prevalence of hospital admission for PAD with or without the use of stimulant abuse (methamphetamine and cocaine) across the United States. Additionally, we evaluated the PAD-related hospitalizations trend stratified by age, race, sex, and geographic location. We used the National Inpatient Sample (NIS) database from 2008 to 2020. The Cochran Armitage trend test was used to compare the trend between groups. Multivariate logistic regression was used to examine adjusted odds for PAD and CLI hospitalizations among methamphetamine and cocaine users. Between 2008 and 2020, PAD-related hospitalizations showed an increasing trend in Hispanics, African Americans, and western states, while a decreasing trend in southern and Midwestern states (p-trend <0.05). Among methamphetamine users, an overall increasing trend was observed in men, women, western, southern, and midwestern states (p-trend <0.05). However, among cocaine users, PAD-related hospitalization increased significantly for White, African American, age group >64 years, southern and western states (p-trend <0.05). Overall, CLI-related hospitalizations showed an encouraging decreasing trend in men and women, age group >64 years, and CLI-related amputations declined for women, White patient population, age group >40, and all regions (p-trend <0.05). However, among methamphetamine users, a significantly increasing trend in CLI-related hospitalization was seen in men, women, White & Hispanic population, age group 26-45, western, southern, and midwestern regions. There was an increasing trend in PAD-related hospitalizations among methamphetamine and cocaine users for both males and females. Although an overall decreasing trend in CLI-related hospitalization was observed for both genders, an up-trend in CLI was seen among methamphetamine users. The upward trends were more prominent for White, Hispanic & African Americans, and southern and western states, highlighting racial and geographic variations over the study period.

Comparison of Treatment Receipt and Hospitalization Among Patients With Stimulant Use Disorder and/or Opioid Use Disorder in the Veterans Health Administration.

Stimulant use is a growing problem, but little is known about service utilization among patients with stimulant use disorder (StUD). In the context of the overdose crisis, much research has focused on patients with opioid use disorder (OUD). It is unclear how the characteristics, treatment receipt, and hospitalization of patients with StUD differ from patients with OUD. Electronic health record data were extracted for national Veterans Health Administration patients with a visit from March 1, 2020, to February 28, 2021 with StUD and/or OUD (N = 132,273). We compared patients with StUD without OUD to those with (1) co-occurring StUD + OUD and (2) OUD without StUD. Patient characteristics, substance use disorder treatment, and hospitalizations in the year following patients' first study period visit were descriptively compared. Treatment and hospitalization were also compared in adjusted regression models. Compared with patients with OUD + StUD, those with StUD without OUD were less likely to receive outpatient (adjusted odds ratio [aOR] 0.49, 95% confidence interval [CI] 0.47-0.50) or any treatment (aOR 0.47, 95% CI 0.46-0.49). Compared with patients with OUD without StUD, those with StUD without OUD were less likely to receive outpatient (aOR 0.51, 95% CI 0.49-0.52) or any treatment (aOR 0.56, 95% CI 0.54-0.58) and more likely to receive residential treatment (aOR 2.18, 95% 2.05-2.30) and to be hospitalized (aOR 1.62, 95% 1.56-1.69). Patients with StUD may be less likely to receive treatment and more likely to be hospitalized than patients with OUD. Efforts focused on mitigating hospitalization and increasing treatment receipt for patients with StUD are needed.

Interrelation between subjective assessment of mental state and perception of family relations by relatives caring for patients with addiction

The addictive disorder often becomes a difficult experience for the all family. Studying the factors influencing the level of psychological distress of addicted patients’ relatives is necessary to create an effective system of psychological assistance for them.Purpose: to reveal the interrelations between the subjective assessment of the mental state and the perception of family relationships among relatives of patients with pathological gambling (PG) and relatives of patients with stimulant use disorder (SUD).Materials and methods. In a cross-sectional study 100 and 41 patients’ relatives were included in the PG and SUD groups respectively. The Symptom Checklist-90-Revised (SCL-90-R) and the Family Environment Scale (FES) was used as an assessment tools. Socio-demographic and clinical data were also collected.Results. The analysis of interrelations between the severity of psychopathological symptoms and the perception of family relationships in the studied groups determined both general and specific correlations. In both groups there are multiple negative correlations between the majority of SCL-90-R scales and the “Cohesion” scale (FES). The specific interrelations included, for example, multidirectional correlations between the “Expressiveness” scale (FES) and psychopathological symptoms scales of the SCL-90-R. Increased expressiveness in the PG group was associated with less severity of psychopathological symptoms and level of distress, and, on the contrary, a greater severity of psychological distress in respondents of the SUD group. Analysis of the correlations in PG compared to SUD showed greater predictability of the connections between psychopathological symptoms and perception of family relationships in the PG group. Thus, the indicators of psychopathological symptoms and psychological distress are negatively associated with parameters reflecting the perception of family cohesion, trust in intrafamily relations, social activity and family organization and, at the same time, have positive interrelations with the indicator of conflict in family relationships.Conclusion. The perception of the family cohesion function as the intrapsychic protection that facilitate the relatives’ adaptation in the emerging life situation, regardless of the form of patients’ addiction.

Iraq's Meth Crisis: Prioritizing Research to Combat Suicidal Ideation

As dedicated readers of Al-Kindy College Medical Journal, we are writing to highlight a critical and profoundly concerning matter that requires urgent research attention: the alarming surge in suicidal ideation among users of Iraqi crystal methamphetamine. Expert psychiatrists at Baghdad Medical City and Ibn-Rushd Psychiatry Teaching Hospital have observed this worrisome trend. In tandem, previous studies regarding suicidal ideation among Iraqi medical students have revealed an unexpectedly high prevalence (64.9%). The escalating global trend in amphetamine-type stimulant (ATS) abuse and the distinct challenges posed by crystal meth addiction necessitate comprehensive investigation into the resultant psychological toll.According to the World Drug Report 2022, amphetamines' popularity and use, including methamphetamine, have surged globally, ranking as the second most commonly abused illicit substance after cannabis. This rise in ATS abuse has not spared Iraq, where illicit methamphetamine and captagon use have dramatically increased, notably in Al-Basrah governorate. The transition from opioid-related overdose deaths to the abuse of stimulants like methamphetamine signifies the urgency for novel strategies to monitor and combat this growing public health concern. As methamphetamine misuse becomes more prevalent, it is imperative to prioritize research that explores the mental health consequences of its abuse.

Injury Pattern Analysis to Optimize Burn Injury Prevention in the Unhoused Community.

Unhoused patients are an overrepresented group in burn injury, and are a uniquely vulnerable population. Current research focuses on the consequences of homelessness on burn outcomes, with little known about the specific circumstances and behaviors leading to burn injury that may represent specific targets for injury prevention efforts. The burn registry at an urban regional burn center was queried for burn admissions in unhoused adults from 2019 to 2022. Registry data pulled included demographics, urine toxicology, mechanism of injury, and injury subjective history. Subjective injury history was reviewed to determine more specific injury circumstances and activities during which accidental burns occurred. Demographic and mechanistic trends in burn admissions were explored via descriptive statistics. Among 254 admissions for burns from the unhoused community, 58.1% of patients were positive for stimulants on admission. Among accidental injuries (69.7%), common circumstances included preparing food or beverages, cooking or using methamphetamine, smoking cannabis or tobacco, bonfires, and candles. A specific common circumstance was lighting a cigarette while handling accelerants (6.7%). Interventions for stimulant abuse, as well as outreach efforts to educate unhoused patients about situational awareness, safe handling of accelerants, safe smoking practices, and safe cooking practices, may be effective tools in reducing burn admissions in this vulnerable population.

Amphetamine increases vascular permeability by modulating endothelial actin cytoskeleton and NO synthase via PAR-1 and VEGF-R

Abuse of amphetamine-type stimulants is linked to cardiovascular adverse effects like arrhythmias, accelerated atherosclerosis, acute coronary syndromes and sudden cardiac death. Excessive catecholamine release following amphetamine use causes vasoconstriction and vasospasms, over time leading to hypertension, endothelial dysfunction or even cardiotoxicity. However, immediate vascular pathomechanisms related to amphetamine exposure, especially endothelial function, remain incompletely understood and were analyzed in this study. Pharmaco-pathological effects of acute d-amphetamine-sulfate (DAM) were investigated ex vivo using contraction–force measurements of rat carotid artery rings and in vitro using label-free, real-time electrochemical impedance spectroscopy (EIS) on endothelial and smooth muscle cells. Specific receptor and target blocking was used to identify molecular targets and to characterize intracellular signaling. DAM induced vasodilation represented by 29.3±2.5% decrease in vascular tone (p<0.001) involving vascular endothelial growth factor receptor (VEGF-R) and protease activated receptor 1 (PAR-1). EIS revealed that DAM induces endothelial barrier disruption (−75.9±1.1% of initial cellular impedance, p<0.001) also involving VEGF-R and PAR-1. Further, in response to DAM, Rho-associated protein kinase (ROCK) mediated reversible contraction of actin cytoskeleton resulting in endothelial barrier disruption. Dephosphorylation of Serine1177 (−50.8±3.7%, p<0.001) and Threonine495 (−44.8±6.5%, p=0.0103) of the endothelial NO synthase (eNOS) were also observed. Blocking of VEGF-R and PAR-1 restored baseline eNOS Threonine495 phosphorylation. DAM induced vasodilation, enhanced vascular permeability and actin cytoskeleton contraction and induced eNOS hypophosphorylation involving VEGF-R, PAR-1 and ROCK. These results may contribute to a better understanding of severe adverse cardiovascular effects in amphetamine abuse.

Stimulant Drug Using, Road Traffic Accidents, and Illegal Activities among Highway Drivers in Iraq in 2022: A Nation-Wide Cross-Sectional Survey

Background: Drug and stimulant abuse is especially common in low and middle- income countries, such as Iraq and certain populations, such as highway drivers. Moreover, Iraq has high rates of traffic and road accidents. Objective: Our objective was to assess the associations of using stimulants with traffic events among highway drivers in Iraq. Methods: We used a cross-sectional study design, in which a self-administered questionnaire was distributed online on different social media platforms. The study included male highway drivers who used drugs from all provinces of Iraq. The questionnaire consisted of demographic questions and an addiction questionnaire about stimulants specially validated for the Arabic language. We followed a convenience sampling method to recruit participants. Results: A total of 1700 participants from 18 provinces were included with a median (IQR) age of 34 (24:55) years. Around 58% used drugs for reasons other than medical indications, while 81% reported abusing prescription drugs. Amphetamine and cocaine were used by 52% and 20% of the participants, respectively. Around 84% of the drivers had at least 56 driving hours per week, while 87% were involved in illegal activities due to drug use. Most of the participants (78%) had accidents at least three times per month. Most of the participants had social and medical issues. Conclusion: Drug use, especially stimulant use, is a major contributor to road accidents and thus, increased morbidity and mortality rates in Iraq. Urgent policies and regulations are needed regarding the dispensing of drugs and the working hours of the drivers.

Reduced brain connectivity underlying value-based choices and outcomes in stimulant use disorder

BACKGROUND: Patients with stimulant use disorder (SUD) show impairments when making value-based choices that are associated with disruptions in neural processing across brain networks. Making optimal choices requires learning from outcomes to update knowledge and further optimise ongoing behaviour. The optimal functioning of neural systems that underpin the ability to make favourable choices is an essential component for life functioning, and successful recovery in patients with SUD. Therefore, we sought to investigate the neural processes that underpin value-based choices in SUD patients. We hypothesise that patients with SUD have reduced functional connectivity while making financial choices during a probabilistic reinforcement learning task. METHODS: We investigated connectivity associated with loss and reward value-based choices and their outcomes in patients with SUD and healthy control participants during a pharmacological magnetic resonance imaging study. Participants received a single dose of a dopamine receptor agonist, pramipexole, and a dopamine receptor antagonist, amisulpride, in a randomised, double-blind, placebo-controlled, balanced, crossover design. Functional task-related connectivity was analysed taking a whole brain connectomics approach to identify networks that are differentially modulated by dopaminergic receptor functioning. RESULTS: SUD patients showed widespread reductions in connectivity during both reward and loss value-based choices and outcomes, which were negatively correlated with the duration of stimulant drug use. Disturbances to functional brain connectivity in SUD patients during task performance were not modulated acutely by either amisulpride or pramipexole. CONCLUSIONS: Reductions in brain connectivity, particularly when making value-based choices and processing outcomes, may underlie learning impairments in SUD patients. Given that acute dopaminergic modulation did not improve brain connectivity impairments in SUD patients, it is likely that alternative treatments are needed.

Стационарная помощь пациентам с зависимостью от новых психоактивных веществ: Исследование тренда

Introduction. The growing number of cases of use of new psychoactive substances (NPS) poses a significant problem for the entire public health of the country, as it requires improved clinical approaches to the treatment of such conditions. At the same time, there is a growing need to analyze the needs for such services. Purpose of this study: was to determine the trend in the provision of inpatient drug treatment services to people with NPS addictions over a five-year period (2016-2020), as well as the dynamic characteristics of NPS drug use patterns over a three-year period (2018-2020). Methods. A longitudinal observational study design was used, e.g. trend analysis for the period from 2016 to 2020. We analyzed exclusively cases of receiving inpatient drug treatment for the first time in each calendar year with diagnoses of synthetic cannabinoid and synthetic stimulant use disorders. Results. A preliminary screening of medical records identified 344 cases in 2018, 614 in 2019, and 708 in 2020. Thus, in the country as a whole, there was a stable increase in the share of initial hospitalizations per year with diagnoses of NPS addiction: from 3.91% (3.2%; 4.7%) in 2016 to 23.91% (22.41%; 25.48%) in 2020. In all regions where patients with NPS addiction were identified, an upward trend was observed. The exception was the North Kazakhstan region and the city of Astana. When assessing the use of NPS, it was revealed that the prevalence of abuse of synthetic stimulants had an upward trend and made up the absolute majority of the observed cases. Conclusions. This study demonstrated a stable exponential increase in the number of inpatients with NPS dependence, while remaining uneven in this indicator in different regions over the five-year period from 2016 to 2020. Over a three-year period, the absolute majority of synthetic stimulant use disorders has persisted among the entire class of NPS. The dynamics of NPS use patterns remain largely stable (methods of anesthesia, frequency and rhythm of NPS use per week and during the day). However, there has been an increase in the proportion of addicts combining NPS and alcohol, which requires further assessment and interpretation.

Gender differences in the prevalence of stimulant misuse in the United States: 2015-2019.

The gender gap in prevalence of substance-use disorders has narrowed. However, gender differences in stimulant misuse have not been well-characterized in recent years. The aim of this study was to quantify gender differences in past-year stimulant misuse and stimulant-use disorder, separated by stimulant type (cocaine/crack, prescription stimulants, and methamphetamine). In an exploratory aim, we investigated whether gender differences were moderated by age or sexual orientation. We combined data from the National Survey on Drug Use and Health from 2015 to 2019 (unweighted N = 282,768) to test gender differences in the prevalence of past-year stimulant misuse. Results indicated that stimulant misuse was significantly more prevalent in men than women for all stimulant types for both past-year use and past-year use disorder. The magnitude of this sex difference was smallest for prescription stimulants, where men had 1.37 times higher odds of past-year misuse and no gender difference was observed in the prevalence of prescription stimulant-use disorder. The magnitude of gender differences also varied based on both age and sexual orientation. Illicit stimulant misuse continues to be more common in men than in women; however, gender differences are more modest for prescription stimulant misuse, suggesting a narrowing of this historical gender difference.

Agenda-setting in policies related to high-risk sexual behaviours, stimulants, and alcohol abuse in Iranian adolescents

BackgroundThis research article retrospectively analyses the agenda-setting approach of policies concerning high-risk sexual behaviours, stimulant and alcohol abuse among Iranian adolescents.MethodsThis qualitative case study policy analysis involved analysing 51 national documents and conducting interviews with 49 policy-makers and executives. Purposive sampling with a snowball strategy and semi-structured interviews were used. The data was analysed using the framework analysis method, with Kingdon’s multiple streams framework serving as the analytical framework.ResultsThe study has identified the confluence of several factors, including the problem stream, the policy stream and the political stream. Within the problem stream, several factors contributed, such as the prevalence of high-risk behaviours, strong scientific evidence on these behaviours, changes in human immunodeficiency virus (HIV) transmission patterns, increased statistics of poisoning and deaths related to alcohol abuse, and the visit of Iran’s supreme leader to the slums of Mashhad city. The policy stream has two periods of denial and acceptance. The denial period includes considering these high-risk behaviours to be the consequences of western culture, emphasis on the religious aspects and sinfulness of these behaviours, resisting the prevalence of anomalous behavioural patterns, abstinence and religious obligation of chastity, and avoiding ethical corruption. The acceptance period includes adolescents training, fear messages, promotional and cultural activities, parent training, school staff training, providing psychiatric services for withdrawal, counselling and reference to receive specialized services. The political stream involves global attention towards non-communicable diseases and high-risk behaviours, and the significant impact of preventing these behaviours during adolescence on the health status of society. Also, the supreme leader’s attention to social harms, and the establishment of the National Committee for Prevention and Control of Alcohol, have played significant roles.ConclusionsWhile the problem stream helped to highlight the problem and increase policy-makers’ attention, the politics stream played a significant role. Despite international evidence on the effectiveness of training in sexual issues in reducing high-risk behaviours, it did not succeed in being added to the agenda. The policy stream was heavily influenced by ideology and the political parties in power, affecting evidence-based policy-making. In countries with an ideological approach, the political stream plays a vital role in setting problems on the agenda.

Impact of COVID-19 on stimulant use disorder treatment: A national cohort study in the Veterans Health Administration

ObjectiveRates of stimulant overdose have increased dramatically, which may have been exacerbated by treatment disruptions during the pandemic, but no recent studies have examined use of stimulant use disorder (StUD) treatment. MethodsIn this retrospective cohort study (March 2018 to February 2022) of national Veterans Health Administration patients, we use an interrupted time-series analysis to examine the impact of COVID-19 (starting in March 2020) on treatment use for StUD. ResultsThe number of patients receiving StUD care was increasing pre-COVID (22,640–23,020, February 2018-February 2020) but dropped post-pandemic to 18,578 in February 2022. The monthly number of patients receiving StUD care increased by 34.6 patients per month (95% CI, 1.1–68.0; P=0.04) before March 2020, decreased by 2803.3 patients (95% CI, −3912.3 to −1694.3; P <0.001) in March 2020, and, accounting for pre-COVID trends, further decreased by 85.85 patients per month (95% CI,−148.9.2 to −23.0; P =0.01) after March 2020. ConclusionsCare for StUD drastically declined during the COVID-19 pandemic and has yet to show signs of a return to pre-pandemic levels despite surging rates of stimulant-involved overdose deaths and a critical need to engage people with StUD in care.

Starting the Discussion: A Call to Enhance Care for People With Stimulant Use Disorder.

Stimulant use disorder (StUD) significantly contributes to substance-related morbidity and mortality in the United States. Overshadowed by the country's focus on opioid-related overdose deaths, stimulant and stimulant/opioid overdose deaths have increased dramatically over the last decade. Many individuals who use stimulants illicitly or have StUD have multiple, intersecting stigmatized characteristics which exacerbate existing barriers and create new obstacles to attaining addiction treatment. Illicit stimulant use, StUD, and stimulant-related overdose disproportionately impact minoritized racial and gender, and sexuality diverse groups. Historically, people who use illicit stimulants and those with StUD have been highly stigmatized, criminalized, and overly ignored by health care providers, policymakers, and the public compared to people who use other drugs and alcohol. As a result, most people needing treatment for StUD do not receive it. This is partly due to the lack of evidence-based treatment for StUD, which has resulted in few programs specializing in the care of people with StUD. The lack of available treatment is compounded by high rates of StUD in marginalized groups already reluctant to engage with the health care system. As health care professionals, we can improve outcomes for people with StUD by changing how we talk about, document, and respond to illicit stimulant use, related characteristics, behaviors, and social and structural determinants of health. To do this, we must seek to understand the lived realities of people with StUD and illicit stimulant use and use this knowledge to amend existing models of care.

Synaptic remodeling of GluA1 and GluA2 expression in the nucleus accumbens promotes susceptibility to cognitive deficits concomitant with downstream GSK3β mediated neurotoxicity in female mice during abstinence from voluntary oral methamphetamine

Stimulant-use disorders can present with long-term cognitive and mental health deficits. Little is known about the underlying molecular mechanisms perpetuating sex differences in cognitive and behavioral deficits in preclinical models of addiction to stimulants such as methamphetamine (MA). The current study investigated the neurochemical shifts underlying sex disparities in MA-induced working memory deficits and an addictive phenotype following abstinence from chronic MA abuse. We used our previously reported mouse model of voluntary oral methamphetamine administration (VOMA) consisting of an acquisition phase (days 1–14) characterized by escalating doses of MA and a binge phase (days 14–28) characterized by static doses. Female VOMA mice exhibited sustained MA consumption during the binge phase, demonstrating sex-specific vulnerabilities to the maintenance of MA addiction. The 8-arm radial maze was used to test spatial working memory performance following abstinence from VOMA. Results indicate working memory deficits correlated to higher MA consumption in females only. Hippocampal and accumbal tissue were collected and analyzed by immunoblotting. Female VOMA mice had decreased GluA1, but not GluA2, in the hippocampus, which may perpetuate synaptic destabilization and working memory deficits. Female-specific increases in GluA1 and p-GSK3β expression in accumbal tissue suggest vulnerability toward abstinence-induced drug craving and heightened downstream neurotoxicity. Our study reveals female-specific neurochemical shifts in hippocampal and accumbal AMPA receptor signaling following abstinence from chronic MA consumption that may perpetuate female susceptibility to MA-induced cognitive deficits. These data demonstrate a novel molecular pathway that would exacerbate memory deficits and perpetuate an addictive phenotype in female populations following MA abuse.
