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.

Long-term efficacy of a new 6-session cognitive behavioral therapy for adults with attention-deficit/hyperactivity disorder: A randomized, controlled clinical trial

BACKGROUND

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that affects about 2.8 % of the adult population. Cognitive behavioral therapy (CBT) has been demonstrated to be the most effective psychological intervention for ADHD. The aim of this study was to explore the efficacy of a new 6-session CBT program in comparison with a 12-session CBT program for adults with ADHD at short- and long-term.

METHODS

81 adults with ADHD (58 % males; mean age = 41.27±9.26 years old) were randomly assigned to each treatment condition (6- or 12-session CBT). Validated instruments were used to assess ADHD symptoms, comorbidities (anxiety and depression), and functional impairments at post treatment, and at 3- and 6-month follow-up.

RESULTS

A significant improvement in ADHD severity, comorbidities (anxiety and depression) and functional impairments were found in both CBT programs after treatment. Furthermore, this improvement was also reported at 3- and 6-month follow-up.

CONCLUSION

The current study highlights that a 6-session CBT program is as effective as a 12-session CBT program for ADHD improvement at post treatment and follow-up. The newly developed 6-session CBT program can be used to treat a larger number of patients, reducing the financial cost.

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.

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.

The clinical course of comorbid substance use disorder and attention deficit/hyperactivity disorder: protocol and clinical characteristics of the INCAS study

BACKGROUND

Substance use disorders (SUD) often co-occur with attention deficit hyperactivity disorder (ADHD). Although the short-term effects of some specific interventions have been investigated in randomized clinical trials, little is known about the long-term clinical course of treatment-seeking SUD patients with comorbid ADHD.

AIMS

This paper presents the protocol and baseline clinical characteristics of the International Naturalistic Cohort Study of ADHD and SUD (INCAS) designed and conducted by the International Collaboration on ADHD and Substance Abuse (ICASA) foundation. The overall aim of INCAS is to investigate the treatment modalities provided to treatment-seeking SUD patients with comorbid ADHD, and to describe the clinical course and identify predictors for treatment outcomes. This ongoing study employs a multicentre observational prospective cohort design. Treatment-seeking adult SUD patients with comorbid ADHD are recruited, at 12 study sites in nine different countries. During the follow-up period of nine months, data is collected through patient files, interviews, and self-rating scales, targeting a broad range of cognitive and clinical symptom domains, at baseline, four weeks, three months and nine months.

RESULTS

A clinically representative sample of 578 patients (137 females, 441 males) was enrolled during the recruitment period (June 2017-May 2021). At baseline, the sample had a mean age (SD) of 36.7 years (11.0); 47.5% were inpatients and 52.5% outpatients; The most prevalent SUDs were with alcohol 54.2%, stimulants 43.6%, cannabis 33.1%, and opioids 14.5%. Patients reported previous treatments for SUD in 71.1% and for ADHD in 56.9%. Other comorbid mental disorders were present in 61.4% of the sample: major depression 31.5%, post-traumatic stress disorder 12.1%, borderline personality disorder 10.2%.

CONCLUSIONS

The first baseline results of this international cohort study speak to its feasibility. Data show that many SUD patients with comorbid ADHD had never received treatment for their ADHD prior to enrolment in the study. Future reports on this study will identify the course and potential predictors for successful pharmaceutical and psychological treatment outcomes.

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.

Online interventions for cannabis use among adolescents and young adults: Systematic review and meta-analysis

BACKGROUND

Young people present high rates of cannabis use, abuse, and dependence. The United Nations estimates that roughly 3.8% of the global population aged 15-64 years used cannabis at least once in 2017. Cannabis use in young people may impair cognitive skills, interfere with learning, impact relationships, and lead to long term behavioural and psychological consequences. Online cannabis interventions (OCI) are increasingly popular, but their dissemination is not often supported by empirical evidence.

AIM

To systematically compile and analyse the effectiveness of OCI for the reduction of cannabis use among adolescents and young adults (AYA).

METHODS

Pooled effect sizes of cannabis use between treatment and control groups were estimated. For each comparison, Hedge's g was calculated using a random effects model.

RESULTS

The search strategy yielded 4531 articles. Of those, a total of 411 articles were retrieved for detailed evaluation resulting in 17 eligible studies (n = 3525). Analyses revealed that online interventions did not significantly reduce cannabis consumption (Hedge's g = -0.061, 95% CI [-0.363] to [-0.242], p = .695) and high heterogeneity was noted (Q = 191.290). More recent studies using structured interventions, daily feedback, AYA centred designs, and peer support, specifically targeting CU seemed to have positive effects to address CU in this population.

CONCLUSIONS

The lack of positive outcomes suggests that more specific and targeted interventions may be necessary to promote cannabis-related behavioural change among young people. These targeted interventions may include structured CU modules, daily feedback, peer support for increased adherence, user-centred design procedures, and input from key stakeholders such as families and service providers.

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.

The impact of insomnia disorder on adult attention-deficit/hyperactivity disorder severity: A six-month follow-up study

BACKGROUND AND OBJECTIVES

The longitudinal relationship between insomnia disorder and adult attention-deficit/hyperactivity disorder (ADHD) has been scarcely investigated. This study aimed to evaluate the relationship between the remission of insomnia disorder and adult ADHD clinical severity, psychiatric and medical comorbidities, and the health-related quality of life (HRQoL) in a 6-month follow-up.

METHODS

Ninety-two adult patients with ADHD and insomnia disorder (52.2% males; mean age 39.5 ± 11.0 years) were comprehensively assessed at baseline, 3 months, and 6 months of a follow-up period. The evaluation included semi-structured interviews (for ADHD and comorbidity assessment), the Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Epworth Sleepiness Scale. The diagnosis of ADHD and insomnia disorder was performed according to DSM-5 criteria. At baseline and follow-up, psychoeducation/sleep hygiene and, if necessary, pharmacological were prescribed for insomnia.

RESULTS

Eighty-seven patients completed the 6-month follow-up. Insomnia disorder remission was reported in 72.4% of cases and was related to a greater improvement in ADHD symptoms and severity throughout the follow-up period. Additionally, an improvement in psychiatric comorbidities and better HRQoL were associated with insomnia disorder remission.

CONCLUSION

The current study highlights that the treatment of insomnia disorder in ADHD adult patients may have an important role in the outcome of ADHD therapeutic approaches by reducing their severity.

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.

Medically Serious Suicide Attempts in Personality Disorders

Medically serious suicide attempts (MSSA) represent a subgroup of clinically heterogeneous suicidal behaviors very close to suicides. Personality disorders (PD) are highly prevalent among them, together with affective and substance use disorders. However, few studies have specifically analyzed the role of PD in MSSA. These suicide attempts (SA) are usually followed by longer hospitalization periods and may result in severe physical and psychological consequences. The aim of this study is to compare the profile of MSSA patients with and without PD. MSSA were defined according to Beautrais 'criteria, but had to remain hospitalized ≥48 h. Overall, 168 patients from two public hospitals in Barcelona were evaluated during a three-year period. Mean hospital stay was 23.68 (standard deviation (SD) = 41.14) days. Patients with PD (n = 69) were more likely to be younger, female, make the first and the most serious SA at a younger age, reported recent stressful life-events and more frequently had previous suicide attempts compared to those without PD. However, no differences were found with regards to comorbid diagnoses, current clinical status, features of the attempt, or their impulsivity and hopelessness scores. Therefore, focusing on the subjective, qualitative experiences related to MSSA among PD patients may increase understanding of the reasons contributing to these attempts in order to improve prevention strategies in the future.

Impact of COVID-19 on Families of Pediatric Solid Organ Transplant Recipients

OBJECTIVE

The COVID-19 pandemic and lockdown measures have had a clear psychological impact on families, and specifically those with children with chronic illnesses have reported greater overloads and exhaustion. The objective of this study was to evaluate the exposure, impact and experience of the pandemic on families of pediatric solid organ transplant (SOT) recipients compared to families of healthy children and adolescents.

METHODS

We recruited 96 families, 48 with a pediatric SOT recipient and 48 healthy controls, matched by child age and gender. A primary caregiver from each family responded to an online sociodemographic questionnaire and the COVID-19 Exposure and Family Impact Survey (CEFIS), which explores the exposure, impact and experience of the pandemic and lockdown on families.

RESULTS

Exposure to the pandemic was greater in families of healthy children and adolescents. The impact was mostly negative in both groups: caregivers reported increased anxiety (76%) and mood disturbances (71.9%) and hindered quality of sleep (64.6%) and health habits (58.3%). On the positive side, family relationships improved. Qualitatively, the SOT group positively perceived isolation and established hygienic measures as protective and destigmatizing, although they reported fear of virus transmission to their child.

CONCLUSIONS

The psychological impact of the pandemic has been similar in both groups, although families of transplant recipients have protected themselves more, probably because they are used to prevention measures and they see contagion as a graver risk. Additionally, SOT recipients' families presented some idiosyncratic elements, especially a decrease in their perception of stigma associated with the medical condition.

Insomnia at the onset of addiction treatment may be related to earlier relapses: A one-year follow-up study

Introduction

Insomnia has been related to a more severe substance use disorder presentation (1). There are few longitudinal studies in outpatients center for SUD treatment that evaluate how insomnia impacts on relapses.

Objectives

To analyze how insomnia impacts on the time of the first substance relapse in SUD outpatients after the onset of addiction treatment.

Methods

This is a one-year follow-up study performed on 116 patients (73.3% males; mean age 43.4±14.3) for whom we had information from baseline insomnia and the time for the first relapse. A Kaplan-Meier survival analysis was performed. This is part of a greater research on Alexithymia in SUD in a longitudinal study.

Results

The initial sample consisted of 116 patients, information on relapses was available for 113 patients. The main substances used at baseline were alcohol (62.1%), cocaine (56.0%), cannabis (42.2%), and opiates (30.2%).

Conclusions

It is important to evaluate insomnia at the onset of addiction treatment because insomnia may be related to earlier relapses. Furthermore, it should be analyzed further on how insomnia treatment impact on substance relapses. REFERENCES 1. Miller MB, Donahue ML, Carey KB, Scott-Sheldon LAJ. Insomnia treatment in the context of alcohol use disorder: A systematic review and meta-analysis. Drug Alcohol Depend. 2017;181:200-207. doi:10.1016/j.drugalcdep.2017.09.029

Treatment retention and abstinence of patients with substance use disorders according to addiction severity and psychiatry comorbidity: A six-month follow-up study in an outpatient unit

INTRODUCTION

The impact of psychiatric comorbidity and addiction features throughout the course of addiction has been widely studied. This is a naturalistic study conducted in an outpatient unit, where treatment follow-up studies are scarce compared to studies including inpatients or those under experimental conditions. Therefore, this follow-up study aims to analyze the treatment adherence and abstinence of outpatients with SUD (Substance Use Disorders) according to addiction severity and psychiatric comorbidity.

METHODS

The current six-month follow-up study examined 404 SUD outpatients. Psychiatric comorbidity, addiction severity, substance consumption and treatment adherence were systematically evaluated using semistructured interviews. Survival analyses were conducted to compare the time of treatment adherence and abstinence in a bivariate and multivariate level.

RESULTS

A progressive dropout was observed, reaching 32.2% of dropouts at the six-month follow-up. More than 50% achieved abstinence during the first month and similar percentages were found until the six-month follow-up. At the multivariate level, treatment adherence, cannabis use disorder and polyconsumption were independently associated with earlier dropout. ADHD was the only mental disorder significantly related with dropout. Regarding substance consumption, the time of abstinence was independently associated with months of treatment adherence and the achievement of abstinence before starting treatment. In general, dual diagnosis was associated with less time of abstinence, but only depressive disorder across the lifespan was related to less time of abstinence in the multivariate model.

CONCLUSION

These findings highlight the importance of an accurate diagnosis at the beginning of treatment, especially in an outpatient setting, addressing the treatment needs and promoting strategies that improve treatment adherence and reduce the risk of relapses.

Psychiatric Comorbidity and Addiction Severity Differences in Patients With ADHD Seeking Treatment for Cannabis or Cocaine Use Disorders

Objective: The objective of this study was to compare psychiatric comorbidity and consumption-related variables in ADHD patients seeking treatment for cocaine, cannabis, or both. Method: Assessment was conducted using European Addiction Severity Index (EuropASI), Conners' Adult ADHD Diagnostic Interview (CAADID), Structured Clinical Interview for DSM Disorders (SCID), Adult Self-Report Scale (ASRS), Wender Utah Rating Scale (WURS), Barratt Impulsiveness Scale-11 (BIS-11), and FIDI, with statistical analyses of analysis of variance (ANOVA), Student's t test, chi-square test, and multinomial regression model. Results: In total, 1,538 patients with substance use disorder (SUD) were evaluated for ADHD; 239 (15.5%) had ADHD, with cannabis 41, cannabis/cocaine 36, and cocaine 74. Men represented 80%, with mean age of 32.9 ± 10 years. Significant variables were-in bivariate analysis-more years of cannabis use in cannabis group and younger age for cocaine use disorder in cannabis/cocaine group, and-in multivariate analysis-lifetime anxiety disorder and younger age at onset of any SUD in cannabis group and working affected scale in cannabis and polysubstance use in cannabis/cocaine group. Conclusion: Groups with cannabis use had higher severity. ADHD features were similar in all groups. The assessment of ADHD and comorbid disorders is important.

Patients with substance use disorder who have higher alexithymia levels present more suicidality history: Preliminary results in an outpatient addiction treatment center in Spain

Introduction

Patients with substance use disorders (SUD) have higher alexithymia levels and present frequently suicidal ideation (SI) and suicide (SA) [1,2]. Beside, alexithymia has been related to suicidal behaviors in several psychiatric disorders[3]. Although, there are some studies on alexithymia and suicidality in SUD patients, to our knowledge there are no studies on this issue in Spanish population.

Objectives

To compare the alexithymia levels in SUD patients with and without SI and SA in an outpatient addiction treatment center in Spain.

Methods

This is a cross-sectional study performed on 110 patients (74.3%males; mean age 43.6±14.5years old) for whom we had information from the Toronto Alexithymia Scale(TAS-20) and the presence or not of lifetime SI and SA.

Results

Lifetime SI and SA were present in 55.5% and 35.5% of the sample respectively. The mean score of TAS-20, difficulties identifying feelings (DIF), difficulties describing feelings (DDT), and externally-oriented thinking(EOT) were 57.2±13.3, 20.0±7.0, 14.7±4.5, and 22.5±4.5 respectively.

Conclusions

SI and SA may be related to alexithymia levels. Hence, alexithymia should be further analyzed in SUD patients in longitudinal studies in order to analyze the bilateral association with suicidal spectrum behaviors.

Catatonia Related to Cannabis and Synthetic Cannabinoids: A Review

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.

Exploring allele specific methylation in drug dependence susceptibility

Drug dependence is a neuropsychiatric condition that involves genetic, epigenetic and environmental factors. Allele-specific methylation (ASM) is a common and stable epigenetic mechanism that involves genetic variants correlating with differential levels of methylation at CpG sites. We selected 182 single-nucleotide polymorphisms (SNPs) described to influence cis ASM in human brain regions to evaluate their possible contribution to drug dependence susceptibility. We performed a case-control association study in a discovery sample of 578 drug-dependent patients (including 428 cocaine-dependent subjects) and 656 controls from Spain, and then, we followed-up the significant associations in an independent sample of 1119 cases (including 589 cocaine-dependent subjects) and 1092 controls. In the discovery sample, we identified five nominal associations, one of them replicated in the follow-up sample (rs6020251). The pooled analysis revealed an association between drug dependence and rs6020251 but also rs11585570, both overcoming the Bonferroni correction for multiple testing. We performed the same analysis considering only cocaine-dependent patients and obtained similar results. The rs6020251 variant correlates with differential methylation levels of cg17974185 and lies in the first intron of the CTNNBL1 gene, in a genomic region with multiple histone marks related to enhancer and promoter regions in brain. Rs11585570 is an eQTL in brain and blood for the SCP2 and ECHDC2 genes and correlates with differential methylation of cg27535305 and cg13461509, located in the promoter regions of both genes. To conclude, using an approach that combines genetic and epigenetic data, we highlighted the CTNNBL1, SCP2 and ECHDC2 genes as potential contributors to drug dependence susceptibility.

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.

End of Life Intervention Program During COVID-19 in Vall d'Hebron University Hospital

Introduction: The coronavirus disease 19 (COVID-19) and its consequences have placed our societies and healthcare systems under pressure. Also, a major impact on the individual and societal experience of death, dying, and bereavement has been observed. Factors such as social distancing, unexpected death or not being able to say goodbye, which might predict Prolonged Grief Disorder (PGD), are taking place. Moreover, hospitals have become a habitual place for End of Life (EOL) situations but not in the usual conditions because, for example, mitigation measures prevent families from being together with hospitalized relatives. Therefore, we implemented an EOL program with a multidisciplinary team involving health social workers (HSW) and clinical psychologists (CP) in coordination with the medical teams and nursing staff. Objectives: We aim to describe an EOL intervention program implemented during COVID-19 in the Vall d'Hebron University Hospital (HUVH). We present its structure, circuit, and functions. Descriptive analyses of the sample and the interventions that required psychological and social attention are reported. Material and methods: The total sample consists of 359 relatives of 219 EOL patients. Inclusion criteria were families cared for during the COVID-19 pandemic with family patients admitted to the HUVH in an EOL situation regardless of whether or not the patient was diagnosed with COVID-19. Results: Our program is based on family EOL care perceptions and the COVID-19 context features that hinder EOL situations. The program attended 219 families, of which 55.3% were COVID-19 patients and 44.7% had other pathologies. The EOL intervention program was activated in most of the EOL situations, specifically, in 85% of cases, and 78% of relatives were able to come and say goodbye to their loved ones. An emotional impact on the EOL team was reported. It is necessary to dignify the EOL situation in the COVID-19 pandemic, and appropriate psychosocial attention is needed to try to minimize future complications in grief processes and mitigate PGD.

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.

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.

Insomnia Symptoms in Patients With Substance Use Disorders During Detoxification and Associated Clinical Features

Background: Insomnia is highly prevalent in patients with substance use disorders (SUD), and it has been related to a worse course of addiction. Insomnia during detoxification in a hospital has not been adequately studied. This study aims to compare sociodemographic, clinical, and psychopathological characteristics of SUD patients undergoing a detoxification program, by comorbidity and insomnia symptoms. Methodology: We recruited 481 patients who received pharmacological and psychotherapeutic treatment for detoxification. They were evaluated through semi-structured interviews, standardized questionnaires, and a specific sleep log. A bivariate and multivariate analysis of the data was performed. Results: Insomnia was reported by 66.5% patients, with sleep-maintenance insomnia the most frequent issue, followed by early morning awakening and sleep-onset insomnia. Patients with alcohol use disorder and cannabis use disorder had higher prevalence of sleep-onset insomnia. Patients with cocaine and heroin use disorder had higher prevalence of sleep-maintenance insomnia. Independent factors that allowed the identification of insomnia symptoms included being female (OR: 3.43), polysubstance use (OR: 2.85), comorbid anxiety disorder (OR: 2.02), and prior admission for detoxification (OR: 1.22). Conclusions: Insomnia symptoms are very prevalent in patients admitted for detoxification. The diagnosis and therapeutic strategies for the insomnia symptoms should be improved, especially in women and in patients with greater addiction severity and with anxiety disorders.

Psychiatric Comorbidity in Treatment-Seeking Alcohol Dependence Patients With and Without ADHD

Objective: To estimate the prevalence of ADHD in adult patients treated for alcohol dependence and to analyze the characteristics of consumption and psychiatric comorbidity, in function of a possible ADHD in adulthood. Method: We administered the Adult ADHD Self-Report Scale (ASRS) to 726 alcohol-dependent patients. Clinical diagnosis, following Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR) criteria was made in the first four weeks of treatment. A subsample of 297 patients was evaluated using Conners' Adult ADHD Diagnostic Interview for DSM-IV (CAADID-II) to test the psychometric properties of ASRS. Results: After analyzing the properties of the ASRS (sensitivity: 83.3%; specificity: 66.1%), the prevalence of ADHD, in the whole sample, was estimated to be 16.2%. Being younger, lifetime history of cocaine dependence and the presence of an affective, anxiety or personality disorder were associated with a possible ADHD. Conclusion: The estimated prevalence of ADHD in patients being treated for alcohol dependence is high, and the presence of a possible ADHD in adulthood is associated with an increase in psychiatric comorbidity.

Cocaine relapse and health-related quality of life: a 23 weeks study

INTRODUCTION

Cocaine dependence is a disorder where relapses are frequently presented and many factors are involved. Furthermore, cocaine dependence is associated with poor health-related quality of life (HRQoL) outcomes. This study aims to explore perceived HRQoL as an indicator of drug relapse in cocaine-dependent patients (CDP).

SUBJECTS AND METHODS

A longitudinal study was carried out in CDP during 23 weeks. A consecutive sampling method was applied, 39 participants composed the initial sample (mean age 35.6 years), only 15 participants completed outpatient follow-up period. CDP were assessed with psychiatric and HRQoL instruments (SCID-I, SCID-II, BDI, STAI scale and SF-36) in different points of the study. The patients were followed up, and cocaine relapses were assessed. The sample was divided according with the relapse (early vs. late relapse). Data were compared and analyzed in order to evaluate whether HRQoL measure could be related to cocaine relapse.

RESULTS

There are differences in perceived HRQoL measures between CDP with/without early relapse, especially in Mental health and Social functioning dimensions (p<0.05). Furthermore, Late/relapse-patients have higher improvement of HRQoL than patients with early relapse.

CONCLUSIONS

Perceived HRQoL might predict early relapse and could be a possible predictor tool of potential future relapses. More research in this field is needed.

Sex differences in an old adult sample with substance use disorder: A 6 months follow-up study

Substance use disorder (SUD) is a worldwide concern that has its own particularities regarding age and sex. This study aims to assess the differences between old SUD women and men regarding socio-demographics, clinical factors and outcomes. A 6-months follow-up longitudinal study was conducted in an outpatient center, on a convenience sample of 115 SUD old adults (≥65 years old, average age of 71.57). Descriptive, bivariate, and multivariate analyses were performed. Data showed statistical significant differences between men and women related to sociodemographic variables (marital status, coexistence, criminal records and stress factors), medical and psychiatric conditions (women suffer higher rates of depression and anxiety, with worse health-related quality of life), family records (women had more presence of family psychiatric records) and SUD related parameters (men tend to use more alcohol, had an early onset, consume higher doses, report more craving and more tobacco life use while women had higher rates of prescription drugs use). At 6-month follow-up, the whole sample showed excellent rates of adherence and abstinence, without sex differences. The study points out sex differences on several sociodemographic and clinical variables, indicating their specific needs. This research could facilitate better approaches by considering a sex perspective in SUD old adults.

Benzodiazepine Use Disorder and Cognitive Impairment in Older Patients: A Six-Month-Follow-Up Study in an Outpatient Unit in Barcelona

OBJECTIVE

Adverse health effects including cognitive impairment have been described in older adults with benzodiazepine misuse, although the literature about this issue is scarce. The present study aimed to assess cognitive decline in older adults with benzodiazepine use disorder and changes in cognitive state at the 6-month follow-up, as well as whether patients achieved abstinence.

METHOD

A 6-month follow-up longitudinal study was conducted in an outpatient drug center in Barcelona in a sample of older adults (≥65 years old) who had benzodiazepine use disorder. The sample was compared with an equivalent control group. A neuropsychological protocol was performed at baseline and after 6-month follow-up covering the most important cognitive domains.

RESULTS

The final sample comprised 33 patients with an average age of 73.5 years. At baseline, patients presented impairment in several domains compared with the control group: visual immediate recall (p < .001), visual delayed recall (p < .001), copy (p < .001), working memory (p < .003), immediate verbal learning (p < .002), total words learned (p < .009), set switching (p < .001), verbal fluency (p < .007), speed processing (p < .002), solving problems (p < .006), nonverbal fluency (p < .004), and sustained attention in all three areas omissions (p < .001), variability (p < .001), and perseverance (p < .005). At 6-month follow-up, patients achieving abstinence showed improvement compared with patients in active consumption in visual delayed recall (p < .006), total words learned (p < .010), and verbal fluency (p < .013).

CONCLUSIONS

Benzodiazepine misuse in older adults may produce negative effects on cognitive skills. Recovery of some of these cognitive deficits may be possible with benzodiazepine abstinence.

Pharmacological Treatment of Insomnia Symptoms in Individuals with Substance Use Disorders in Spain: A Quasi-Experimental Study

INTRODUCTION

Pharmacological treatment of insomnia in patients with addictions has been hardly investigated and there are few researches about it in an inpatient detoxification. The aim of this study was to describe the outcomes of the pharmacological treatment of insomnia in SUD patients admitted to a detoxification unit in Spain, with a focus on the primary substance of abuse and co-occurring mental disorders.

METHODS

A quasi-experimental study was conducted in 481 addicted in patients, who were admitted for substances detoxification in Vall d´Hebron University Hospital, Barcelona, Spain, from 2010 to 2015. The patients underwent systematic evaluation of axes I and II psychiatric disorders (SCID-I, SCID-II, and CAADID). Insomnia was evaluated using a night time sleep log. Substance-dependent patients, who had insomnia during hospital detoxification, received a psychotropic medication with hypnotic effect, keeping the regular clinical practice without randomization.

RESULTS

At discharge, insomnia was considered to have been alleviated in 63.8% (n = 204) of patients while 36.2% (n = 116) of patients remained with insomnia disturbances. Comparing hypnotic treatments it was observed that mirtazapine and clotiapine were the treatment that corrected the insomnia more frequently.

DISCUSSION

Since insomnia is not corrected in all patients, it should be further investigated in medications with hypnotic purpose. Based on the results of this work, randomized clinical trials might be proposed.

Factors associated with lifetime suicidal ideation and suicide attempts in outpatients with substance use disorders

Risks factors for suicide are multiple and highly prevalent in addicted patients (previous suicide attempts, substance abuse, impulsivity, history of sexual abuse and other factors). The aim of this study is to identify and to compare the clinical and socio-demographic profile of SUD outpatients with lifetime suicidal behavior (previous suicidal ideation and/or suicide attempts) and to analyze the factors related to it. A retrospective cohort study of 696 addicted patients, according to DSM-IV-TR criteria (APA, 2000) were collected from the Addiction Unit of Vall d'Hebron University Hospital. Lifetime suicidal ideation in addicted patients is associated with presence of: borderline personality disorder (BPD), depressive disorders, sexual abuse, polydrug abuse, attention-deficit hyperactivity disorder, and motor impulsivity. The factors associated with suicide attempts were: borderline personality disorder, lifetime abuse (whether emotional, physical or sexual), co-occurrent psychotic disorders, polydrug abuse, anxiety disorders and depressive symptoms. We conclude that previous suicidal ideation and lifetime suicide attempts should be considered in the clinical care of addicted patients. Factors related to both suicidal behaviors share similarities and differences according to our findings and need to be deeply explored in the future.

Anxiety and Depression in Drug-Dependent Patients with Cluster C Personality Disorders

OBJECTIVE

Comorbidity between personality disorders (PD) and substance-use disorders (SUD) is one of the most common findings in the psychiatric field. The patients with Cluster C disorders present maladjustment traits often characterized by high levels of anxiety. The main aim of this study was to find evidences about higher anxiety and depression prevalence on Cluster C than others Clusters, analyzing similarities and differences within, with other Cluster A and B PD patients and patients without PD.

METHOD

A total of 822 substance dependent patients (ages18-78; Mean = 38.35, SD = 10.14) completed the structured clinical interview for DSM-IV Axis I and Axis II disorders, Beck Depression Inventory, and State-Trait Anxiety Inventory.

RESULTS

Results supported poly-consumption in Cluster C patients, being greater alcohol consumption as well as abuse of both stimulants and depressants. Anxiety and depression did not show just one pattern for all patients with SUD-Cluster C PD. There was a relation between anxiety and depression for all the groups except for the Dependent-PD.

CONCLUSION

Interventions should focus on aspects like depression and anxiety more than on the substance consumed.

Early cannabis use and its relation to the development of psychiatric disorders: a review

Background. Cannabis is the most widely used illegal drug in the world. Both an early cannabis use onset and the amount used contribute to the risk of suffering mental disorders in adulthood. Objective. Review longitudinal studies conducted on adolescents associating early cannabis use with the subsequent occurrence of mental disorders. Method. A search was conducted in PubMed until December 2016, focusing on longitudinal researches and prioritizing studies that clearly distinguished between an early and late onset of cannabis use. To achieve the objective, the word “cannabis” was used in combination with the main psychiatric diseases. A manual search of articles that appeared in the references was also conducted. Results. Fifteen studies met the inclusion criteria, but only five studies discriminated clearly between early and late onset of cannabis use. An association was found between early onset of cannabis use and mental disorders, particularly psychosis. The information regarding affective and anxiety disorders is more controversial. Discussion and conclusion. Early onset of cannabis use is associated with mental disorders, especially psychosis. Prevention plans for cannabis use in adolescents should be developed in order to decrease the risk of mental disorders.

The role of dual diagnosis in health-related quality of life among treatment-seeking patients in Spain

PURPOSE

The comorbidity of any substance use disorder and another mental disorder is defined as dual diagnosis. Dual diagnosis is very common and clinical and therapeutic consequences have been described. This cross-sectional study aimed to analyse health-related quality of life (HRQoL) according to clinical characteristics and psychiatric comorbidities in patients with substance dependence.

METHODS

A total of 1276 substance-dependent patients seeking treatment were recruited. HRQoL was evaluated by the Short-Form 36 (SF-36) questionnaire. The SCID-I, SCID-II and Conners' adult ADHD diagnostic interview were used to evaluate dual diagnosis. A visual analogue scale was used to measure craving. Bivariate and multivariate analyses were performed, and correction for multiple tests was conducted.

RESULTS

Substance-dependent patients had impaired quality of life, especially in the mental component. SF-36 physical and mental component scores were 47.7 ± 10.9 and 36.1 ± 14.1, respectively. Furthermore, 65% of the patients had dual diagnosis, 51% had an Axis I DSM-IV-TR mental disorder and 35% had some personality disorder. Impaired physical quality of life was independently associated with medical condition, age, being female, depressive disorder and anxiety disorder. Depression disorder, any personality disorder, active consumption last month, Attention deficit hyperactivity disorder, anxiety disorder, suicide attempt were independently associated with worse mental quality of life.

CONCLUSION

These findings emphasize the significance of dual diagnosis in the impairment of HRQoL in substance-dependent patients, particularly with regard to mental component. In addicted patients with low scores on SF-36, psychiatric comorbidity should be evaluated and treated in an integrated approach.

Cognitive impairment associated with drug use in old age people

Introduction

Substance use disorder is a growing phenomenon among old adults. It is usually significantly undervalued, misidentified, under diagnosed and poorly treated. It has been related to cognitive impairment but there are few studies focused on the elderly.

Aim

To evaluate the relationship between drug use and cognitive impairment in old adults.

Methods

We conducted a prospective study (basal and 6 month follow up) in 67 patients over 65 years old seeking for treatment for drug misuse (alcohol and prescription drugs, mainly benzodiacepines) in addiction and dual diagnosis unit in Barcelona. A specific protocol was performed to evaluate attention, executive function, working memory, learning capacity, fonetic and visual fluency, decision-making, visual construction and cognitive flexibility (FCT, CPT-II, N-BACK, COWAT FAS, TAP, SDMT, IGT, CVLT, TOL, RFFT, STROOP). Patients were compared with a control group (healthy non drug users) with same characteristics (gender, age range and education status). The protocol consisted in two separated sessions of 90 minutes each one performed by a neuropsychologist.

Results

Results obtained suggested that patients under drug misuse had worse scores in fluency, visual construction, memory and attention compared with controls. After 6 month treatment and achieving abstinence patients improve in cognitive skills as verbal learning, short-term memory and free recall of verbal information. Cognitive impairment profile changes depending on the substance abused (alcohol or benzodiacepines).

Conclusions

Drug use can produce deleterious effects in old adults. However, those who achieve abstinence may improve some cognitive functioning as verbal learning, short-term memory and free recall of verbal information.

Comparative study of psychiatric comorbidity differences in patients with ADHD and cocaine substance use disorders and patients ADHD and cannabis use disorders

Substance Use Disorders (SUD) and Attention Deficit Hyperactive Disorder (ADHD) are frequent conditions in out drug treatment centers. There are evidences about the high prevalence of ADHD in SUD patients (20%) compared with just ADHD in general population (1–7.3%). Both disorders and psychiatric comorbidity are important in the diagnosis proceeding. The objective of this study is search the difference in psychiatric comorbidity conditions between patients with ADHD and Cocaine SUD and ADHD and Cannabis SUD. ADHD was present in 158 patients of a total sample in which 46,8% used cocaine, 17.1% cannabis and 36.1% used both. Mood disorders were 26.8% in cocaine users, 21.7% in cannabis and 18.9% in both. Anxiety disorders were 20.3% in cocaine users, 37.5 in cannabis and 13% in both users. Primary psychotic disorders were 2.9% in cocaine users, none in cannabis and 11,1% in both drug users. Personality disorders by cluster were, Cluster A: 11.3% in cocaine group, 36% in cannabis group and 24.5 in cannabis and cocaine group. Cluster B: 33.8% in cocaine group, 44% in cannabis group and 51.9% in cannabis and cocaine group. Cluster C: 9.9% in cocaine group, 28% in cannabis group and 19.2% in cannabis and cocaine group. There could be common pathways of neuronal damage related to psychiatric comorbidity depending of used drug, the differences in comorbidity found in this study could explain a little part of it. It is important to manage SUD-ADHD and other psychiatric comorbidity in order to improve the outcomes of these patients.

Clinical differences between cocaine-dependent patients with and without antisocial personality disorder

The aim of this study is to compare the features of two groups of cocaine dependent patients in treatment, one of them with co-morbid diagnosis of antisocial personality disorder and the other not. Cross-sectional design, with 143 cocaine-dependent patients attending a drug unit, distributed in two groups: patients with and without Antisocial Personality Disorder. As results, we found that the 15.38% of the sample were diagnosed with an Antisocial Personality Disorder. In relation to socio-demographic variables, Antisocial Personality Disorder patients have less probability of being working or studying (9.1% vs. 47.9%). After multivariate analysis it was found that significantly Antisocial Personality Disorder patients have more opiates dependence (OR: 0.219; 95% IC 0.072-0.660), sedative dependence (OR: 0.203; 95% IC 0.062-0.644) and in more cases show Borderline Personality Disorder (OR: 0.239; 95% IC 0.077-0.746). This study highlights significant differences between cocaine addicts with or without an Antisocial Personality Disorder. All these differences are good indicators of the complexity of the patients with this personality disorder. Better knowledge of their profile will help us to improve the design of specific treatment programs.

Higher severity of cocaine addiction is associated with tactile and somatic hallucinations

BACKGROUND

The aim of this study is to describe the features of cocaine-dependent patients who have had cocaine-induced tactile/somatic hallucinations (CITSH), and to analyze the association with addiction-related variables and psychiatric comorbidity, comparing patients with CITSH, patients with cocaine psychotic symptoms (CIP) and no CITSH, and patients without any psychotic symptom.

METHOD

A cross-sectional study was conducted in 767 cocaine-dependent patients in an outpatient treatment center for addictions. The following data were obtained: sociodemographic characteristics, CIP information, addiction-related variables and psychiatric comorbidity. A bivariate and multivariate analysis was performed.

RESULTS

Of the whole sample, 6.6% reported CITSH at some point of their lives, 48.4% had suffered some CIP other than CITSH, and 45% had not experienced any psychotic symptom. According to multivariate analysis, risk of overdose increases by 12.1 (OR) times the probability of having had CITSH compared patients with CIP-no-CITSH. Other variables associated to patients with CITSH were: age of drug use onset, presence of episodes of overdose, prevalence of psychotic disorder induced by cocaine. In general, in all variables studied, patients with CITSH presented worse clinical features (addiction variables and psychiatric comorbidity) than patients with CIP without CITSH and non-CIP group.

CONCLUSION

CITSH are usually associated with other psychotic symptoms induced by cocaine. The patients who experienced CITSH are more severe cases compared both with patients with CIP without CITSH and patients without CIP. Increased risk of overdose is an important issue in this type of patients.

Impulsivity and addiction severity in cocaine and opioid dependent patients

BACKGROUND

Impulsivity as a personality trait is a risk factor for the development and maintenance of cocaine and opioid dependence. The objective of this study is to analyze the relationship between impulsivity and addiction severity in cocaine and opioid dependent patients.

METHODS

A cross-sectional, observational study of 526 patients with lifetime cocaine dependence (CD, n=351), opiate dependence (OD, n=51) and comorbid cocaine and opiate dependence (COD, n=124) to throughout life, according to DSM-IV-TR, was conducted. The sample was recruited at the Addiction and Dual Diagnosis Unit of Vall d'Hebron University Hospital from January 2006 to April 2013. Patients were evaluated with the EuropASI, the SCID I and II interviews, and the Barratt Impulsivity Scale (BIS-11). Descriptive statistics of the main variables (including mean, standard deviation) was performed. Chi square test was used to compare categorical variables and Kruskal-Wallis test to compare continuous variables. Spearman correlation was used to analyze the relationship between EuropASI scores and BIS-11 scores.

RESULTS

The mean age of the patients was 36.37years±8.08 (19-66). CD and COD were more impulsive and had higher addiction severity than OD. OD patients had worse medical status than CD and COD patients while COD patients had more severe drug use and legal problems than the other groups. However, impulsivity and addiction severity were only positively correlated in CD patients.

CONCLUSIONS

Impulsivity should be appropriately screened and addressed in cocaine dependents as it may be related to addiction severity.

Risk factors for temporary work disability

INTRODUCTION

The relationship among labor difficulties and psychiatric disorders is important and bidirectional. However, current information about the influence of psychiatric disorders in temporary work disability in Spain is inconclusive. For this reason, we aimed to describe the prevalence of the conclusions of psychiatric expert&#8217;s reports including maintain o revoke the temporary disability (TD). We also aimed to compare sociodemographic, clinical and therapeutic variables according with the decision of maintain or revoke this condition.

METHODOLOGY

A descriptive study was conducted in psychiatric patients that were examined by psychiatric experts during one year. At the examination time, the patients had a sick leave mean of 5 months. The psychiatric experts assessed their ability to work according to the interference of the psychiatric symptoms.

RESULTS

A total of 380 patients were included (66.8% women, 42±10.9 years), 87.9% had a result of revoke the temporary work disability. No sociodemographic or therapeutic factors were associated with the continuity of sick leave. The most common diagnosis of patients who obtained a revoked temporary work disability was adjustment disorder (66.2% vs 13%, p=0.001) and patients who maintained the temporary work disability was major depressive disorder (45.7% vs 3.9%, p=0.001).

CONCLUSIONS

After a psychiatric expert&#8217;s examination the most of the results suggest to revoke the temporary work disability. Major depressive disorder is the most commonly diagnostic associated to continue sick leave.

Administrative prevalence of insomnia and associated clinical features in patients with addiction during active substance use

INTRODUCTION

A bidirectional relation between substance use and insomnia has been described, although there are few studies examining insomnia in the population of people with addiction. The aim of this study was to describe the prevalence of insomnia during active substance use in patients with addiction and its associated clinical features.

PATIENTS AND METHODS

Descriptive study in patients diagnosed with substance dependence disorder admitted to a Hospital Detoxification Unit. The existence of insomnia prior to admission was assessed using the Oviedo Sleep Questionnaire (OSQ). Demographic variables, consumptionrelated clinical variables, and diagnostic variables were collected and the SCID-I and -II (Structured Clinical Interview for DSM-IV) and CAADID (Conners&#8217; Adult ADHD Diagnostic Interview for DSM-IV) were administered to evaluate the psychiatric diagnoses. Bivariate and multivariate analyses were made of the data.

RESULTS

481 patients (72.6% men, age 40.6±10.1 years) were enrolled. 64.3% of the patients reported insomnia during active substance use. The most common type of insomnia was fragmented nocturnal sleep (49.9%). The factors significantly associated with insomnia were polysubstance drug use, medical comorbidities (most notably, infectious diseases), anxiety disorder, personality disorder (particularly cluster C), a greater number of previous admissions for detoxication, and early age at onset of substance use.

CONCLUSIONS

Insomnia is highly prevalent in patients with addiction during active use of the substance. Fragmented nocturnal sleep was the most common type of insomnia. Patients with addiction and comorbid anxiety disorder, medical comorbidity, and early onset of dependence were more likely to experience insomnia.

Related factors with substance use in old adults

Intro

Substance use disorder is a growing phenomenon among the elderly. It is undervalued, misidentified, underdiagnosed and poorly treated.

Aim

Study prevalence, characteristics and risk factors associated with drug use among the elderly.

Method

A 6-month prospective study of substance use in elderly patients (65+) who attended the addiction and dual diagnosis unit, Vall d’Hebron University Hospital.

Results

Fifty-nine patients evaluated, mean age 70.04 years, 60% men. A total of 49.1% are married, 35.8% divorced and 53.8% live with a partner and/or children. A total of 67.3% have basic studies and 78.8% are pensioners. A total of 82.7% have no criminal record.

Medical comorbidity presents in 90.4% of the sample, psychiatric and addictive family background in 42.3% and 37.3%. A total of 67.3% have comorbid Axis I (mainly affective disorders) and 25% Axis II (cluster B most). A total of 7.7% attempted suicide at least once.

The main substance is alcohol (76.9%), followed by prescription drugs (19.3%). A total of 28.8% are multi-drug users. A total of 67.3% have used tobacco in their life and 63.5% are currently dependent. The average age of onset for a disorder for any substance consumption is 28.19, being lower for alcohol and illegal substances and higher for prescription drugs.

A total of 61.5% have gone through treatment before but only 32.7% has been admitted because of addiction. The adherence rate is 90.4% and the relapse rate 8.3% at first month and 13% at 6 months.

Conclusions

Old adults present differences compared to overall drug user population: prevalence by gender is almost equal, lower Axis II, less multi-drug consumption and both dropout and relapse rate are drastically lower.

Risk factors for accidents among cocaine-dependent patient seeking treatment

Introduction

Accident rate have a high social cost. Cocaine consumption increases the risk of traffic crashes (Monras, 2011; Fierro, 2011). However, there is not extensively studies in addicts.

Objective

Compare and analyze the history of accidents and risk behaviors while driving in cocaine dependent patients (DC) and of other substances (OtherD).

Methods

One hundred and eighty-two patients seeking treatment since January 2014 to September 2015. Sociodemographic and accident-related variables were collected, also administered the MDBQ. Descriptive analysis and bivariate analysis using Chi-square test for categorical variables and Student t test was performed for quantitative.

Results

Of women, 30.3%, and 69.7% men, mean age 43.67 years (SD = 13). 65.6% currently driving or above. 45.2% DC vs. 54.8 DOther (35.6% alcohol, cannabis 8.3%, 5.8% opioid and 5.1% other drugs).

Comparing accident rate on the DC is a tendency to have suffered more accidents (χ2: 2.62 P=.072). Patients addicted to cocaine referred further potentially dangerous activities both under the influence of consumption (65.9% vs. 33.3%) and abstinence (41.7% vs. 12%).

As for the results of MDBQ, it has been detected that cocaine addicts show more errors and traffic violations. No differences in the lapses identified by patients of different groups.

Conclusion

Patients with cocaine dependence have more accidents, reduced risk perception and recognize more mistakes and traffic violations. Cocaine implies a high risk of road accidents and exposure to high-risk situations compared to the use of other substances.

Self-perceived quality of life in cocaine dependents with or without dual diagnosis

Abstract Introduction. Although impairment in the quality of life is common among cocaine dependent patients, there are but a few researches about the interaction between addiction and quality of life. Objective. To study different parameters of quality of life in a sample of cocaine dependent patients and to compare patients with or without dual diagnosis. Also, to promote the importance of subjectivity in the quality of life and to propose to incorporate patients’ self-perception into their treatment. Method. Three diagnostic interviews were administered (SCID-I, SCID-II and PRISM) and a quality of life questionnaire (SF-36) was applied between two different patient groups: Group I (cocaine dependent patients) and Group II (cocaine dependent patients with other mental disorder). Results. Patients diagnosed with dual disorders (Group II) showed broader differences in perceptions of their quality of life in comparison with their clinicians. The perception of quality of life may vary depending on the presence and severity of mental disorders, and these different appreciations may explain the difficulties that clinicians face in understanding their patients’ expectations and motivations. Discussion and conclusion. A systematic evaluation of the subjective quality of life should be included in the management of cocaine dependent patients in order to more accurately understand the patients’ perception of their treatment, motivations and expectations.

Motivational interviewing group at inpatient detoxification, its influence in maintaining abstinence and treatment retention after discharge

The relapse rate after discharge from inpatient detoxification is high. The objective of this pilot study is to assess the sociodemographic, clinical and therapeutic factors associated with maintaining abstinence in patients who participated in a brief motivational interviewing group during admission for detoxification. A total of 46 patients, diagnosed substance dependent according to DSM -IV, and admitted to the Hospital Detoxification Unit, participated in a brief motivational interviewing group. Sociodemographic, clinical, motivation to change (University of Rhode Island Change Assessment, URICA) and satisfaction with the treatment group (Treatment Perceptions Questionnaire, CPT) data were collected. Abstinence and treatment retention two months after discharge were assessed by weekly telephone calls. A survival analysis was performed. Being male, having more cognitions of the maintenance stage of change at discharge, being satisfied with group therapy and therapist during hospitalization are associated with longer abstinence after discharge. The brief motivational interviewing group approach with patients admitted for detoxification is related to greater likelihood of maintaining abstinence and subsequent treatment retention.

Adult ADHD screening in alcohol-dependent patients using the Wender-Utah Rating Scale and the adult ADHD Self-Report Scale

OBJECTIVE

The aim was to analyze the psychometric properties of two screening instruments, Wender-Utah Rating Scale (WURS) that evaluates childhood ADHD and Adult ADHD Self-Report Scales (ASRS) that assesses symptoms in adulthood, in alcohol-dependent patients.

METHOD

A total of 355 outpatients were included. Conners' adult ADHD diagnostic interview results were used as a gold standard in childhood and adulthood ADHD.

RESULTS

The WURS with a 41 cutoff had a sensitivity of 79.6% and a specificity of 60.3%. The ASRS with a 14 cutoff had a sensitivity of 86.7% and specificity of 66.1%. Analyzing both rating scales in combination, it was observed that patients with positive ASRS and WURS presented a sensitivity of 92.3%. Patients with positive ASRS, but negative WURS, presented a specificity of 73.6%.

CONCLUSION

WURS and ASRS are useful tools in the diagnosis of adult ADHD in alcohol-dependent patients; with the use of both instruments, the psychometric properties are substantially improved.

Changes in brain-derived neurotrophic factor (BDNF) during abstinence could be associated with relapse in cocaine-dependent patients

Brain-derived neurotrophic factor (BDNF) is involved in cocaine craving in humans and drug seeking in rodents. Based on this, the aim of this study was to explore the possible role of serum BDNF in cocaine relapse in abstinent addicts. Forty cocaine dependent subjects (DSM-IV criteria) were included in an inpatient 2 weeks abstinence program. Organic and psychiatric co-morbidities were excluded. Two serum samples were collected for each subject at baseline and at after 14 abstinence days. After discharge, all cocaine addicts underwent a 22 weeks follow-up, after which they were classified into early relapsers (ER) (resumed during the first 14 days after discharge,) or late relapsers (LR) (resumed beyond 14 days after discharge). The only clinical differences between groups were the number of consumption days during the last month before detoxification. Serum BDNF levels increased significantly across the 12 days of abstinence in the LR group (p=0.02), whereas in the ER group BDNF remained unchanged. In the ER group, the change of serum BDNF during abstinence negatively correlated with the improvement in depressive symptoms (p=0.02). These results suggest that BDNF has a role in relapse to cocaine consumption in abstinent addicts, although the underlying neurobiological mechanisms remain to be clarified.
