Comparing nurses attending a specialised mental health programme with and without substance use disorder: a retrospective, observational study in Spain.

OBJECTIVES: To analyse the differences between nurses with and without substance use disorders (SUDs) admitted to a specialised mental health programme. DESIGN: Retrospective, observational study. SETTING: Specialised mental health treatment programme for nurses in Catalonia, Spain. PARTICIPANTS: 1091 nurses admitted to the programme from 2000 to 2021. INTERVENTIONS: None. PRIMARY AND SECONDARY OUTCOMES: Sociodemographic, occupational and clinical variables were analysed. Diagnoses followed Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision criteria. RESULTS: Most nurses admitted to the programme were women (88%, n=960) and came voluntarily (92.1%, n=1005). The mean age at admission was 45 (SD=10.4) years. The most common diagnoses were adjustment disorders (36.6%, n=399), unipolar mood disorders (25.8%, n=282), anxiety disorders (16.4%, n=179) and SUDs (13.8%, n=151). Only 19.2% (n=209) of the sample were hospitalised during their first treatment episode. After multivariate analysis, suffering from a SUD was significantly associated with being a man (OR=4.12; 95% CI 2.49 to 6.82), coming after a directed referral (OR=4.55; 95% CI 2.5 to 7.69), being on sick leave at admission (OR=2.21; 95% CI 1.42 to 3.45) and needing hospitalisation at the beginning of their treatment (OR=12.5; 95% CI 8.3 to 20). CONCLUSIONS: Nurses with SUDs have greater resistance to voluntarily asking for help from specialised mental health treatment programmes and have greater clinical severity compared with those without addictions. SUDs are also more frequent among men. More actions are needed to help prevent and promote earlier help-seeking behaviours among nurses with this type of mental disorder.

Abstinence duration and psychopathology among addiction outpatients during 18 months of COVID-19.

Background: The COVID-19 pandemic has impacted the mental health of patients with substance use disorder (SUD). However, few longitudinal studies have been done which examine associations between the pandemic, SUD patients' mental health and their drug use. Objectives: This study aimed to examine duration of abstinence according to psychiatric status among SUD outpatients followed-up for 18 months from the pandemic related lockdown. Methods: A follow-up study of 316 SUD outpatients was undertaken. Sociodemographic features, and clinical and consumption related variables were recorded. Pre, during and post lockdown information was evaluated. Abstinence/substance use was monitored at the patient's scheduled follow-up appointments, and psychiatric disorders and psychological variables were revaluated at 18 months. Results: Survival analyses were used to compare the duration of abstinence (in months) from the beginning of the lockdown. It was observed that 70% of patients consumed the main substance for which they were being treated at some point during the follow-up. Men, younger patients, those with more symptoms of anxiety and personality disorders, and patients who experienced increased craving during follow-up, showed shorter duration of abstinence. While patients who had previously maintained at least one year of abstinence, achieved better results. Conclusions: During the first year and a half of the pandemic, SUD outpatients presented alterations in mental health, such us anxiety, depression and maladaptive personality traits and a high rate of relapse. For this reason, despite the health and social crisis and their restrictive measures, a comprehensive treatment should be ensured.

CLINICAL VIEW ON SUBSTANCE-INDUCED PSYCHOTIC SYMPTOMS IN A MEDICALLY SUPERVISED INJECTING ROOM: A DECADE OF EXPERIENCE.

Medically supervised injecting rooms (MSIRs) are extremely important facilities for people who inject drugs (PWID) as MSIRs provide a safe place for the consumption of street-sourced drugs, impacting overdose rates and viral transmitted infections.

Shared decision making in patients with substance use disorders: A one-year follow-up study.

Patient-centered care in therapeutic processes has been associated with better clinical outcomes, however, it remains a poorly studied aspect in Substance Use Disorder (SUD). The study aimed to evaluate patient's preferences, perceived participation in treatment decisions and activation level; and how they predict retention, pharmacological adherence and substance use during one-year follow-up. Logistic regression models were used to analyze the association between independent variables, along with a wide number of sociodemographic and clinical covariates, and outcomes. Most patients prefer a shared or passive role when making decisions about their treatment, and showed concordance between their preferred and perceived roles. In the univariate models, perceiving more involvement than desired showed a higher likelihood of treatment discontinuation at 12 months, and substance use at 6 and 12 months. No significant associations were found between the remaining decisional variables or the degree of activation with the assessed outcomes. A majority of SUD patients prefer and perceive to be involved in the decision-making process about their treatment. Patients perceiving more involvement than desired might experience an excess of responsibility that could negatively influence treatment continuation and substance use. Limitations of the study preclude any definitive conclusion, and more research is needed to confirm these results.

Combined COVID-19 vaccination and hepatitis C virus screening intervention in marginalised populations in Spain.

BACKGROUND: COVID-19 has hindered hepatitis C virus (HCV) and HIV screening, particularly in marginalised groups, who have some of the highest rates of these conditions and lowest rates of COVID-19 vaccination. We assessed the acceptability of combining HCV testing with COVID-19 vaccination in a centre for addiction services (CAS) in Barcelona and a mobile testing unit (MTU) in Madrid, Spain. METHODS: From 28/09/2021 to 30/06/2022, 187 adults from marginalised populations were offered HCV antibody (Ab) testing along with COVID-19 vaccination. If HCV Ab+, they were tested for HCV-RNA. MTU participants were also screened for HIV. HCV-RNA+ and HIV+ participants were offered treatment. Data were analysed descriptively. RESULTS: Findings show how of the 86 CAS participants: 80 (93%) had been previously vaccinated for COVID-19, of whom 72 (90%) had the full first round schedule; none had a COVID-19 vaccine booster and all received a COVID-19 vaccine; 54 (62.8%) were tested for HCV Ab, of whom 17 (31.5%) were positive, of whom all were tested for HCV-RNA and none were positive. Of the 101 MTU participants: none had been vaccinated for COVID-19 and all received a COVID-19 vaccine; all were tested for HCV Ab and HIV and 15 (14.9%) and 9 (8.9%) were positive, respectively; of those HCV Ab+, 9 (60%) were HCV-RNA+, of whom 8 (88.9%) have started treatment; 5 (55.6%) of those HIV+ had abandoned antiretroviral therapy, of whom 3 (60%) have re-started it. CONCLUSIONS: The intervention was accepted by 54 (62.8%) CAS participants and all MTU participants and can be used in marginalised communities.

The COVID-19 pandemic has reduced the numbers of people being screened to determine whether they are infected with the hepatitis C virus (HCV) or HIV. This is particularly the case for marginalised populations, which include people with substance use disorders (e.g., injecting drug use), those who are experiencing homelessness, and those with mental health disorders. This study explored whether these populations were willing to be tested for HCV after receiving a COVID-19 vaccination in a centre for addiction services in Barcelona and a mobile testing unit (MTU) in Madrid, Spain. Those attending the MTU were also screened for HIV. Most participants were both vaccinated and tested for HCV and HIV, as applicable, when offered. Applying this approach more widely could improve healthcare reach among marginalised populations.

Clinical features and factors related to lifetime suicidal ideation and suicide attempts in patients who have had substance-induced psychosis across their lifetime.

Suicidal behaviors are common among patients with substance use disorders (SUD). However, the prevalence and clinical factors related to suicide behaviors among patients who have had substance-induced psychosis (SIP) is unknown. This study aims to explore the prevalence, clinical features, and factors related to lifetime suicidal ideation (SI) and suicide attempts (SA) in patients who have had SIP across their lifetime. A cross-sectional study was conducted in an outpatient center for addiction treatment between 01/01/2010 and 12/31/2021. 601 patients were evaluated with validated scales and questionnaires (79.03% males; M age 38.11±10.11 years). The prevalence of SI and SA was 55.4% and 33.6%, respectively. SI was independently related to any type of lifetime abuse, depressive spectrum disorders, benzodiazepine use disorder, borderline personality disorder, and the level of depressive symptoms. SA was independently associated with lifetime physical abuse, benzodiazepine use disorder, the number of psychotic symptoms, borderline personality disorder, and the level of depressive symptoms. The main factors related to SI and SA in those patients should be evaluated in daily clinical practice and considered in any approach to clinical practice as well as in health policies targeting suicide prevention.

Validity of the ADHD module of the Mini International Neuropsychiatric Interview PLUS for screening of adult ADHD in treatment seeking substance use disorder patients: ADHD screening with MINI-Plus.

OBJECTIVE: This study aims to assess the validity of the ADHD module of the Mini-International Neuropsychiatric Interview (MINI-Plus) in patients with substance use disorders (SUD), using the Conners' Adult ADHD Diagnostic Interview for DSM-IV (CAADID) as the external criterion. METHOD: A cross sectional international multi-center study in 10 countries was conducted in treatment seeking SUD patients. A sample of 1263 patients with both MINI-Plus and CAADID was analyzed to determine the psychometric properties of the MINI-Plus. RESULTS: According to the CAADID, 179 patients (14.2%) met criteria for adult ADHD, whereas according to the MINI-Plus 227 patients (18.0%) were identified as having adult ADHD. Sensitivity of the MINI-Plus ADHD module was 74%, specificity was 91%, positive predictive value was 60% and negative predictive value was 96%. Kappa was 0.60. CONCLUSION: The MINI-Plus has acceptable criterion validity for the screening of adult ADHD in treatment seeking SUD patients. SCIENTIFIC SIGNIFICANCE: On the basis of the results, The MINI-Plus may be used for the screening of ADHD in SUD patients.

Spanish validation of the Brief Problem Gambling Screen in patients with substance use disorders. / Validación al castellano de la escala Brief Problem Gambling Screen en pacientes con Trastorno por Uso de Sustancias.

Problematic Gambling or Gambling Disorder (GD) can act by initiating and maintaining the problem of substance addiction. Despite this, there are no rapid screening tools validated in Spanish. The Brief Problem Gambling Screen (BPGS) has proven to be one of the most sensitive tools for detecting GD and populations at risk. This study aims to validate the Spanish version of the original five-item BPGS. A sample of 100 Spanish-speaking adults with substance use disorder were recruited from an addiction treatment center. The participants were administered the Spanish version of BPGS. It showed strong item reliability properties (Ω = 0.93). Sensitivity and specificity values were excellent (0.93 each), also positive (0.7) and negative (0.99) predictive values suggest high discriminant power when compared to non-GD subjects. Statistically significant strong correlation with a gold-standard measure (Problem Gambling Severity Index) was found (r = 0.8, p < 0.01). Similar psychometric properties were found in at-risk gambler patients. In conclusion, the BPGS seems to be an adequate screening instrument in Spanish-speaking clinical population, and also identifies at-risk of GD subjects.

El juego patológico (JP) puede actuar iniciando y manteniendo el problema de la adicción a sustancias. A pesar de ello, no existen herramientas de cribado rápido validadas en español. La Breve evaluación del juego problemático (BPGS) ha demostrado ser una de las herramientas más sensibles para detectar JP y poblaciones en riesgo. Este estudio tiene como objetivo validar la versión en español de la BPGS original de cinco factores. Se reclutó una muestra de 100 adultos hispanohablantes con trastorno por uso de sustancias de un centro de tratamiento de adicciones. A los participantes se les administró la versión en español de la BPGS. El instrumento mostró propiedades de fiabilidad de los ítems evaluados (Ω = 0,93). Los valores de sensibilidad y especificidad fueron excelentes (0,93 cada uno), también los valores predictivos positivos (0,7) y negativos (0,99) sugieren un alto poder discriminante en comparación con los sujetos sin JP. Se encontró una fuerte correlación significativa con la medida gold-estándar (índice de severidad del juego problemático, PGSI) (r = 0,8, p < 0,01). Se encontraron propiedades psicométricas similares en pacientes en riesgo de JP. En conclusión, la BPGS parece un buen instrumento de cribado en la población clínica española, y también identifica a los sujetos en riesgo de desarrollar JP.

Confirmatory factor analysis of 20-item toronto alexithymia scale in spanish patients with substance use disorder.

Alexithymia is highly prevalent in patients with substance use disorders (SUDs) and has been implied in SUD pathogenesis and treatment outcomes. However, the psychometric properties of the most-used instrument for evaluating alexithymia (the 20-item Toronto Alexithymia Scale, TAS-20) have been scarcely studied in relation to SUD patients.

A Feasibility Study of Patients with Major Depression and Substance Use Disorders: Vortioxetine as Maintenance Treatment.

Background: Limited studies have evaluated the effectiveness of vortioxetine in real-world settings, and none of them has involved patients with dual depression (major depressive disorder [MDD] and substance use disorder [SUD]). The objective of the study was to describe the effectiveness of vortioxetine in clinical practice and determine its effect on affective symptoms, cognitive function, quality of life, and substance use in patients with MDD and SUD. Methods: Post-authorization, retrospective, multicenter, descriptive, and observational study in 80 patients with MDD and SUD receiving a maintenance treatment with vortioxetine for six months between January 2017 and April 2021. Results: Compared with baseline, scores significantly decreased after 3 and 6 months of treatment in the Montgomery-Åsberg Depression Rating Scale total (from 28.9 to 17.7 and 12.0), and global functional impairment of the Sheehan Disability Inventory (from 26.3 to 19.1 and 16.7). The number of correct answers in the symbol digit modalities test significantly improved during vortioxetine treatment (from 40.4 to 43.8 and 48.4). Regarding the clinical global impression scale, the score for disease severity significantly decreased from 3.8 to 3.0 and 2.4. Compared with baseline, there was a significant reduction in consumption of practically all substances, especially of alcohol, cannabis, and cocaine. Conclusion: Vortioxetine was effective in clinical practice for alleviating depressive symptoms and functional impairment, and in improving cognitive and executive functions and disease severity in patients with MDD and SUD. Moreover, the treatment with vortioxetine favored a reduction in substance use and the severity of the SUDs.

A Multicenter Study on the Impact of Gender, Age, and Dual Diagnosis on Substance Consumption and Mental Health Status in Outpatients Treated for Substance Use Disorders During COVID-19 Lockdown.

Objective COVID-19 and lockdown measures impacted mental health globally and had a particular impact on patients with substance use disorders (SUD). However, the impact of gender, age, and dual diagnosis on consumption patterns and mental health during COVID-19 lockdown among patients with SUD has not been analyzed in depth. Therefore, this study aimed to examine substance use and mental health status during COVID-19 lockdown considering gender, age, and previous dual diagnosis in patients with SUD treated in different outpatient addiction clinics in Catalonia. Methods: Thirteen clinics participated and 588 patients were enrolled in the study, of whom 70.7% were men and 29.3% were women. The mean age was 48 ± 11.3 years, and 63.2% had dual diagnoses. Results: Men reported significantly more frequent alcohol and cocaine consumption during lockdown, while women experienced more anxiety and depressive symptoms. Younger patients more frequently reported consuming cocaine and cannabis, breaking the lockdown rule, worsened family relationships, and reduced incomes. Older patients more frequently reported maintaining abstinence. Previous dual diagnosis was more often associated with benzodiazepine use disorder, less active working during lockdown, and more anxiety and depressive symptoms than not having previous dual diagnosis. Conclusions: Both new psychiatric symptoms and general worsening of existing symptoms were frequent during the lockdown. Differences based on the gender, age, and dual diagnosis of outpatients treated for substance use disorders should be considered in the planning of protection measures such as home confinement.

COVID-19 Lockdown and Consumption Patterns among Substance Use Disorder Outpatients: A Multicentre Study.

INTRODUCTION: COVID-19 has had a great impact on mental health in the general population. However, few studies have focused on patients with substance use disorders (SUDs). This research aimed to compare the clinical status and substance use patterns of SUD outpatients, before and during confinement due to the COVID-19 pandemic. METHODS: This multicentre study recruited 588 patients (29.2% women; M age = 47.4 ± 11.7 years) in thirteen centres for addiction treatment in Catalonia, Spain. All subjects were evaluated with validated instruments and ad hoc questionnaires. The sample was divided into 3 groups according to how the substance consumption pattern changed during lockdown (maintained pattern, worsened pattern, and improved pattern). RESULTS: More than 62% of the patients maintained or worsened their consumption pattern during confinement, and about 38% improved throughout this time. Diverse factors were associated with the changes in pattern like age, addiction severity, psychological distress during lockdown, social and familial issues, and therapeutic variables. CONCLUSION: The home lockdown during the COVID-19 pandemic was associated with major implications for substance consumption and psychiatric distress among SUD outpatients. Considering this, the need to plan appropriate interventions in cases of similar health crises is highlighted.

Barriers to linkage to care in hepatitis C patients with substance use disorders and dual diagnoses, despite centralized management.

BACKGROUND: Hepatitis C virus (HCV) management is a challenge in patients with substance use disorder (SUD). This study aimed to describe an HCV screening and linkage to care program in SUD patients, and analyze the characteristics of this population in relation to HCV infection, particularly the impact of psychiatric comorbidities (dual diagnosis). METHODS: This study was a prospective clinical cohort study using a collaborative, multidisciplinary model to offer HCV care (screening, diagnosis, and therapy) to individuals with SUD attending a dedicated hospital clinic. The characteristics of the participants, prevalence of HCV infection, percentage who started therapy, and adherence to treatment were compared according to the patients' consumption characteristics and presence of dual diagnosis. HCV screening, diagnosis, treatment initiation, and sustained virologic response were analyzed. RESULTS: 528 individuals attended the center (November 2018-June 2019) and 401 (76%) accepted screening. In total, 112 (28%) were anti-HCV-positive and 42 (10%) had detectable HCV RNA, but only 20 of the latter started HCV therapy. Among the 253 (63%) patients with a dual diagnosis, there were no differences in HCV infection prevalence versus patients with SUD alone (p = 0.28). Dual diagnosis did not lead to a higher risk of HCV infection or interfere with linkage to care or treatment. CONCLUSION: This study found a high prevalence of dual diagnosis and HCV infection in SUD patients, but dual diagnosis was not associated with an increased risk of acquiring HCV or more complex access to care. Despite use of a multidisciplinary management approach, considerable barriers to HCV care remain in this population that would need more specific focus.

[International Consensus Statement for the Screening, Diagnosis, and Treatment of Adolescents with Concurrent Attention-Deficit/Hyperactivity Disorder and Substance Use Disorder]. / Internationale Konsenserklärung zu Screening, Diagnostik und Behandlung von Jugendlichen und Heranwachsenden mit Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung und gleichzeitigen Störungen durch Substanzgebrauch.

International Consensus Statement for the Screening, Diagnosis, and Treatment of Adolescents with Concurrent Attention-Deficit/Hyperactivity Disorder and Substance Use Disorder Abstract. Background: Childhood attention-deficit/hyperactivity disorder (ADHD) is a risk factor for substance misuse and substance use disorder (SUD) in adolescence and (early) adulthood. ADHD and SUD also frequently co-occur in treatment-seeking adolescents, which complicates diagnosis and treatment and is associated with poor treatment outcomes. Research on the effect of treatment of childhood ADHD on the prevention of adolescent SUD is inconclusive, and studies on the diagnosis and treatment of adolescents with ADHD and SUD are scarce. Thus, the available evidence is generally not sufficient to justify robust treatment recommendations. Objective: The aim of the study was to obtain a consensus statement based on a combination of scientific data and clinical experience. Method: A modified Delphi study to reach consensus based upon the combination of scientific data and clinical experience with a multidisciplinary group of 55 experts from 17 countries. The experts were asked to rate a set of statements on the effect of treatment of childhood ADHD on adolescent SUD and on the screening, diagnosis, and treatment of adolescents with comorbid ADHD and SUD. Results: After 3 iterative rounds of rating and adapting 37 statements, consensus was reached on 36 of these statements representing 6 domains: general (n = 4), risk of developing SUD (n = 3), screening and diagnosis (n = 7), psychosocial treatment (n = 5), pharmacological treatment (n = 11), and complementary treatments (n = 7). Routine screening is recommended for ADHD in adolescent patients in substance abuse treatment and for SUD in adolescent patients with ADHD in mental healthcare settings. Long-acting stimulants are recommended as the first-line treatment of ADHD in adolescents with concurrent ADHD and SUD, and pharmacotherapy should preferably be embedded in psychosocial treatment. The only remaining no-consensus statement concerned the requirement of abstinence before starting pharmacological treatment in adolescents with ADHD and concurrent SUD. In contrast to the majority, some experts required full abstinence before starting any pharmacological treatment, some were against the use of stimulants in the treatment of these patients (independent of abstinence), while some were against the alternative use of bupropion. Conclusion: This international consensus statement can be used by clinicians and patients together in a shared decision-making process to select the best interventions and to reach optimal outcomes in adolescent patients with concurrent ADHD and SUD.

Effectiveness of tianeptine in patients with major depressive disorder and substance use disorder.

The depressive disorder coexists in a high prevalence with a substance-related disorder, which is asso- ciated with a worst prognosis. The therapeutic interventions for this co-morbidity lack of the appropriate scientific sup- port. The existing evidence suggest that the currently avail- able anti-depressive drugs are of minor efficacy in this group of patients. An alternative would be the use of different drugs with distinctive neurobiological mechanism of action. The aim of this study was to describe the clinical develop- ment of a series of patients affected by this comorbidity un- der treatment with tianeptine under usual clinical practices.

Efectividad de tianeptina en pacientescon depresión mayor y trastorno poruso de sustancias / Effectiveness of tianeptine in patients with major depressive disorder and substance use disorder

Introducción: La depresión coexiste frecuentemente conlos trastornos por uso de sustancias (TUS), lo que conllevaun peor pronóstico. Existe una importante falta de evidenciasobre las intervenciones terapéuticas más efectivas para estacomorbilidad. Los estudios existentes sugieren que los antidepresivos disponibles actualmente son poco eficaces paraestos pacientes. La disponibilidad terapéutica de antidepresivos con mecanismos neurobiológicos diferentes podría seruna alternativa. El objetivo es describir la evolución de ungrupo de pacientes con esta comorbilidad que han realizadotratamiento con tianeptina en condiciones de práctica clínica habitual en consultas de deshabituación.Metodología. Se diseñó un estudio postautorización,multicéntrico, retrospectivo y observacional de práctica clínica habitual. Se revisaron las historias clínicas de los 100últimos pacientes diagnosticados de depresión mayor y TUS,tratados con tianeptina durante al menos 3 meses. Se evaluaron en tres ocasiones (inicial, intermedia y final a los 3meses) las siguientes escalas: Escala de Evaluación para laDepresión de Hamilton (HDRS), Escala de Impresión ClínicaGlobal (ICG) y Escala de Gravedad de la Adicción (SDS).Resultados. La mayoría de los pacientes fueron tratadoscon una combinación de psicofármacos y psicoterapia. Alfinal del seguimiento 70 pacientes (70 %) obtuvieron unaremisión clínica según la escala HDRS y 76 pacientes (76 %)se clasificaron con mucha o moderada mejoría según ICG.Respecto al consumo, los descensos más destacados se produjeron en los trastornos por uso de alcohol y cocaína.Conclusión. Tianeptina, en monoterapia o en combinación, puede ser un tratamiento de utilidad para pacientescon depresión dual de forma conjunta con otras medidasterapéuticas que traten de forma integrada estos pacientescomplejos.

Tianeptine could be a useful drug for thetreatment of patients with dual diagnosis of depression andsubstance-related disorder, together with other therapeuticinterventions. (AU)

Insomnia Disorder in Adult Attention-Deficit/Hyperactivity Disorder Patients: Clinical, Comorbidity, and Treatment Correlates.

Introduction: Several investigations have been performed on insomnia symptoms in adult attention-deficit/hyperactivity disorder (ADHD). However, the relationship between insomnia disorder and adult ADHD has been neglected in research. The main objective of the current study is to analyze the differences between adult ADHD patients with and without insomnia disorder, in terms of ADHD clinical severity, medical and psychiatric comorbidity, psychopharmacological treatment, and quality of life. Material and Methods: Two hundred and fifty-two adult patients with ADHD (mean age 37.60 ± 13.22 years; ADHD presentations-combined: 56.7%, inattentive: 39.7%, hyperactive/impulsive: 3.6%) were evaluated with an exhaustive clinical and psychological evaluation protocol including semistructured interviews (for comorbidities and ADHD assessment) and symptom rating scales for ADHD. The diagnosis of ADHD and insomnia disorder was made according to DSM-5 criteria. Furthermore, the Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Epworth Sleepiness Scale were administered. Results: Insomnia disorder was found in 44.4% of adult ADHD patients and was more common in combined presentation (64.3%) and in patients with more ADHD severity. Comorbidities (both medical and psychiatric), especially mood disorders (42%), anxiety disorder (26.8%), personality disorder (39.3%), and any substance use disorder (11.6%), were associated with a higher insomnia disorder prevalence. ADHD stimulant treatment was related to lower insomnia disorder compared to patients without medication, as well as ADHD stable treatment. Additionally, worse health-related quality of life was associated with insomnia disorder. Conclusion: Insomnia disorder is highly prevalent in adult ADHD and is related to higher ADHD severity and more psychiatric and medical comorbidities. Some stimulants and stable pharmacological ADHD treatment are associated with better outcomes of insomnia disorder.

Alexithymia in Patients With Substance Use Disorders and Its Relationship With Psychiatric Comorbidities and Health-Related Quality of Life.

Background: Alexithymia frequently correlates with several psychiatric disorders, including substance use disorder (SUD). However, most studies reporting the associations between alexithymia and psychiatric disorders have been performed in populations without SUD. This research, therefore, evaluates alexithymia in Spanish patients with SUD and the relationship among alexithymia, psychiatric comorbidities, psychological symptoms/traits, SUD variables, and health-related quality of life (HRQoL). Methodology: A cross-sectional study was conducted with 126 Spanish outpatients with SUD (75.4% males; mean age 43.72 ± 14.61 years), correlating their alexithymia levels (using the Toronto Alexithymia Scale 20 [TAS-20]) to their psychiatric comorbidities, psychological symptoms/traits, SUD variables, and HRQoL. Results: Alexithymia was significantly higher in patients who had cannabis use disorder. Higher alexithymia scores were also related to higher levels of depression, anxiety, impulsivity, and lower HRQoL. After multivariate analysis, trait anxiety, impulsivity, and the physical component summary of the HRQoL were found to be independently related to alexithymia. Conclusions: SUD patients with higher alexithymia levels have more frequently psychiatric comorbidities, present specific psychological features, and have worse HRQoL. Hence, it is important to evaluate these factors and offer more accurate psychotherapeutic approaches for this patient population.

Catatonia Related to Cannabis and Synthetic Cannabinoids: A Review.

OBJECTIVE: Cannabis and synthetic cannabinoids (SC) are related to several neuropsychiatric symptoms and disorders, especially psychotic symptoms and disorders. Interestingly, catatonia-like symptoms associated with cannabis and SC have been generally neglected in research and scarcely described despite the clinical repercussions. Hence, this review aims to analyze current clinical publications on catatonia induced by cannabis or SC in a systematized way. Methods: A search using PRISMA guidelines was performed on three databases based on a specific inclusion and exclusion criteria. Results: 11 publications describing 14 patients (10 males; mean age 22.50 ± 6.67 years old) with catatonia apparently precipitated by the use of cannabis (n = 6) or SC (n = 8) were found. Clinical features and treatment are described and discussed. Conclusion: From a clinical perspective, cannabis and SC use may be related to catatonia-like symptoms and catatonia syndrome in the same way these substances (cannabis and SC) are related to induced-psychotic episodes. However, further research will be required to understand the exact nature of that relationship. Additionally, investigations focused on the clinical significance (i.e., prognosis, evolution, and outcomes) of catatonia-like symptoms induced by cannabis and SC use in patients are also needed.

Psychosis induced by abuse of ayahuasca: a case report.

Ayahuasca is a psychotropic infusion prepared by boiling the bark of Amazonian plants and has many psychopharmacological effects not fully understood. Some of those effects are used as treatment for different diseases. However, the side effects of ayahuasca, including ayahuasca-induced psychosis, are an important issue. Here we report the case of a patient who had a psychotic episode after taking ayahuasca and who was successfully treated with antipsychotic medication. Given the current spread of ayahuasca consumption in developed societies, the present case highlights the need for better understanding and regulation of the social-legal condition of ayahuasca and the need for further research. Additionally, psycho-education seems advisable in order to create awareness of the potential risks of the use of ayahuasca.
