Exploring Attentional Bias toward Alcohol Content: Insights from Eye-Movement Activity.

INTRODUCTION: Attentional bias (AB) is an implicit selective attention toward processing disorder-significant information while neglecting other environmental cues. Considerable empirical evidence highlights the clinical implication of AB in the onset and maintenance of substance use disorder. An innovative method to explore direct measures of AB relies on the eye-movement activity using technologies like eye-tracking (ET). Despite the growing interest regarding the clinical relevance of AB in the spectrum of alcohol consumption, more research is needed to fully determine the AB patterns and its transfer from experimental to clinical applications. The current study consisted of three consecutive experiments. The first experiment aimed to design an ad-hoc visual attention task (VAT) consisting of alcohol-related and neutral images using a nonclinical sample (n = 15). The objective of the second and third experiments was to analyze whether the effect of type of image (alcohol-related vs. neutral images) on AB toward alcohol content using the VAT developed in the first experiment was different for type of drinker (light vs. heavy drinker in the second experiment [n = 30], and occasional social drinkers versus alcohol use disorder (AUD) patients in the third experiment [n = 48]). METHODS: Areas of interest (AOIs) within each type of image (neutral and alcohol-related) were designed and raw ET-based data were subsequently extracted through specific software analyses. For experiment 1, attention maps were created and processed for each image. For experiments 2 and 3, data on ET variables were gathered and subsequently analyzed through a two-way ANOVA with the aim of examining the effects of the type of image and drinker on eye-movement activity. RESULTS: There was a statistically significant interaction effect between type of image and type of drinker (light vs. heavy drinker in experiment 2, F(1, 56) = 13.578, p < 0.001, partial η2 = 0.195, and occasional social drinker versus AUD patients in the experiment 3, F(1, 92) = 35.806, p < 0.001, partial η2 = 0.280) for "first fixation" with large effect sizes, but not for "number of fixations" and "dwell time." The simple main effect of type of image on mean "first fixation" score for AUD patients was not statistically significant. CONCLUSION: The data derived from the experiments indicated the importance of AB in sub-clinical populations: heavy drinkers displayed an implicit preference for alcohol-related images compared to light drinkers. Nevertheless, AB fluctuations in patients with AUD compared to the control group were found. AUD patients displayed an early interest in alcohol images, followed by an avoidance attentional processing of alcohol-related images. The results are discussed in light of recent literature in the field.

Destination Matters More: Relapse following Hospital-Based Treatment of Substance Use Disorders With and Without Co-Occurring Disorders.

OBJECTIVES: Addressing substance use in psychiatric care encounters significant barriers, but the emergence of specialized services offers an opportunity to advance and scale up the integration of addiction services within psychiatric settings. However, research gaps still exist in this field, particularly in understanding the substance relapse rates of people with co-occurring disorders after a psychiatric hospitalization. This study aimed to investigate and compare the relapse rates of patients under inpatient care with exclusively addiction-related issues and those with co-occurring disorders after a hospitalization in a psychiatric ward and gain insights into differences in outcomes for these two patient groups. METHODS: This retrospective analysis examined electronic medical records of patients admitted to the Acute Psychiatry Ward of the Hospital Clinic of Barcelona with a substance use disorder diagnosis between January 2019 and February 2021. Cox regression was used to identify variables independently associated with the first relapse episode. RESULTS: From a total of 318 admissions (79.2% with psychiatric comorbidity), 76.1% relapsed during the study follow-up, with a median survival time of 54 days. Younger age, female gender, voluntary admission, and outpatient follow-up were independently associated with relapse. The presence of a co-occurring disorder was not associated with relapse. CONCLUSION: This study highlights the need for interventions aimed at improving post-discharge abstinence rates for addiction-related hospitalizations. It also challenges the notion that co-occurring disorders automatically imply a worsened prognosis and emphasizes the importance of addressing addiction and psychiatric comorbidity in a comprehensive, integrated, and specialized manner.

Passive exposure to electronic cigarette aerosol in pregnancy: A case study of a family.

BACKGROUND: Passive exposure to the aerosols of electronic cigarettes (e-cigarettes) has been little studied. We assessed this exposure in late pregnancy in a woman and her 3-year-old child, exposed through e-cigarette use by another household member. METHODS: This prospective longitudinal case study involved a family unit consisting of an e-cigarette user, a pregnant woman who delivered an infant during the study, and the couple's older 3-year-old son. At 31, 36, and 40 weeks of the pregnancy, we measured biomarkers (nicotine metabolites, tobacco-specific nitrosamines, propanediols, glycerol, and metals) in the urine and hair of all three participants and in the saliva of the adults, in cord blood at delivery, and in the breast milk at the postpartum period. RESULTS: Samples from the e-cigarette user showed quantifiable concentrations of all analytes assessed (maximum urinary cotinine concentration, 4.9 ng/mL). Among samples taken from the mother, nicotine and its metabolites were found mainly in urine and also in saliva and hair, but not in cord blood. During the postpartum period, we found cotinine concentrations of 2.2 ng/mL in the mother's urine and 0.22 ng/mL in breast milk; 1,2-propanediol was generally detected in urine and saliva, but not in cord blood or breast milk. The maximum urinary cotinine concentration in the 3-year-old child was 2.6 ng/mL and propanediols also were detected in his urine. Nitrosamines were not detected in samples taken from the mother or the 3-year-old. Metals found in the refill liquid were detected at low levels in both the mother and the 3-year-old. CONCLUSIONS: We detected low but not negligible concentrations of e-cigarette-related analytes (including cord blood and breast milk) in an exposed pregnant non-user and in a 3-year-old child also living in the home. Passive exposure to e-cigarette aerosols cannot be disregarded and should be assessed in larger observational studies.

Sodium Oxybate for Alcohol Dependence: A Network Meta-Regression Analysis Considering Population Severity at Baseline and Treatment Duration.

AIMS: The estimated effect of sodium oxybate (SMO) in the treatment of alcohol dependence is heterogeneous. Population severity and treatment duration have been identified as potential effect modifiers. Population severity distinguishes heavy drinking patients with <14 days of abstinence before treatment initiation (high-severity population) from other patients (mild-severity population). Treatment duration reflects the planned treatment duration. This study aimed to systematically investigate the effect of these potential effect moderators on SMO efficacy in alcohol-dependent patients. METHODS: Network meta-regression allows for testing potential effect modifiers. It was selected to investigate the effect of the above factors on SMO efficacy defined as continuous abstinence (abstinence rate) and the percentage of days abstinent (PDA). Randomized controlled trials for alcohol dependence with at least one SMO group conducted in high-severity and mild-severity populations were assigned to a high-severity and mild-severity group of studies, respectively. RESULTS: Eight studies (1082 patients) were retained: four in the high-severity group and four in the mild-severity group. The high-severity group was associated with larger SMO effect sizes than the mild-severity group: abstinence rate risk ratio (RR) 3.16, P = 0.004; PDA +26.9%, P < 0.001. For PDA, longer treatment duration was associated with larger SMO effect size: +11.3% per extra month, P < 0.001. In the high-severity group, SMO showed benefit: abstinence rate RR 2.91, P = 0.03; PDA +16.9%, P < 0.001. In the mild-severity group, SMO showed benefit only in PDA for longer treatment duration: +23.9%, P < 0.001. CONCLUSIONS: In the retained studies with alcohol-dependent patients, high-severity population and longer treatment duration were associated with larger SMO effect sizes.

Education and Training in Addiction Medicine and Psychology across Europe: A EUFAS Survey.

INTRODUCTION: Training in addiction medicine and addiction psychology is essential to ensure the quality of treatment for patients with substance use disorders. Some earlier research has shown varying training between countries, but no comprehensive study of addiction training across Europe has been performed. The present study by the European Federation for Addiction Societies (EUFAS) aimed to fill this gap. METHODS: A Delphi process was used to develop a questionnaire on specialist training in addiction treatment in 24 European countries. The final questionnaire consisted of 14 questions on either addiction medicine or addiction psychology, covering the nature and content of the training and institutional approval, the number of academic professorial positions, and the estimated number of specialists in each country. RESULTS: Information was not received from all countries, but six (Belgium, Denmark, Ireland, Italy, Poland, and Romania) reported no specialized addiction medicine training, while 17 countries did. Seven countries (Belgium, France, Ireland, Italy, Russia, Switzerland, and the Netherlands) reported no specialized addiction psychology training, while 14 countries did. Training content and evaluation methods varied. Approval was given either by governments, universities, or professional societies. Eighteen countries reported having professorships in addiction medicine and 12 in addiction psychology. The number of specialists in addiction medicine or psychology varied considerably across the countries. DISCUSSION: The survey revealed a large heterogeneity in training in addiction medicine and addiction psychology across Europe. Several countries lacked formal training, and where formal training was present, there was a large variation in the length of the training. Harmonization of training, as is currently the case for other medical and psychology specializations, is warranted to ensure optimal treatment for this under-served patient group.

Development of community strategies supporting brief alcohol advice in three Latin American countries: a protocol.

Brief alcohol advice offered to patients was shown to be a clinically- and cost-effective intervention to prevent and manage alcohol-related health harm. However, this intervention is not yet optimally implemented in practice. A suggested strategy to improve the implementation of brief alcohol advice is through community actions which would enhance the environment in which primary healthcare providers must deliver the intervention. However, there has been scarce research conducted to date regarding which community actions have most influence on the adoption and implementation of brief alcohol advice. The current protocol presents the development of a package of community actions to be implemented in three Latin American municipalities, in Colombia, Mexico and Peru. The community actions were based on the Institute for Health Care Improvement's framework for going to full scale, and include: (i) involvement of a Community Advisory Board, (ii) involvement of a project champion, (iii) adoption mechanisms, (iv) support systems and (v) a communication campaign. By presenting a protocol for developing community actions with input from local stakeholders, this article contributes to advancing the public health field of alcohol prevention by potentially stimulating the sustainable adoption and implementation of brief alcohol advice in routine practice.

Systematic review on the clinical management of chronic pain and comorbid opioid use disorder. / Revisión sistemática sobre el manejo clínico del dolor crónico y el trastorno por uso de opioides simultáneo.

The crisis caused by prescribed opioids and their related side effects are a public health problem worldwide. Most of these are prescribed for coping with chronic pain. The coexistence of opioid use disorder (OUD) in patients with chronic pain represents a complex challenge due to the need for managing both pain and OUD. The aim of this systematic review is to evaluate the efficacy of feasible treatments for this population with OUD and comorbid chronic pain for both conditions. A systematic database search has been performed using Cochrane Library, MEDLINE, PsycINFO and ClinicalTrials.gov in compliance with PRISMA guidelines. Eligible articles addressed the outcomes in chronic pain patients with comorbid opioid use disorder after treatment interventions were applied. Of 593 identified articles, nine were eligible for qualitative review (n = 7 pharmacological interventions; n = 2 psychological interventions). Methadone, buprenorphine, cognitive-behavioral and mindfulness showed promising results, but data were inconclusive (<2 RCT with low risk of bias). It is unclear whether the opioid agonist treatment should be maintained or tapered and which drug should be prescribed for the opioid substitution therapy (methadone or buprenorphine/naloxone). Mindfulness and cognitive behavioral therapy have a discrete effect on improving negative affect but not pain. The therapeutic approach might be individualized under a shared decision-making basis.

La crisis causada por los opioides recetados y sus efectos secundarios relacionados son un problema de salud pública en todo el mundo. La mayoría de estos medicamentos se recetan para el afrontamiento del dolor crónico. La coexistencia del trastorno por uso de opioides (TUO) en pacientes con dolor crónico representa un desafío complejo debido a la necesidad de controlar tanto el dolor como el TUO. El objetivo de esta revisión sistemática es evaluar la eficacia de los tratamientos posibles para dicha población con TUO y dolor crónico. Se ha realizado una revisión sistemática usando las bases de datos Cochrane Library, MEDLINE, PsycINFO y ClinicalTrials.gov, conforme a las pautas PRISMA. Los artículos elegibles abordaron los resultados en pacientes con dolor crónico y diagnóstico comórbido de TUO, después de aplicar una intervención. De 593 artículos identificados, nueve eran elegibles para la revisión cualitativa (n = 7 intervenciones farmacológicas; n = 2 intervenciones psicológicas). La metadona, la buprenorfina, la terapia cognitivo-conductual y el mindfulness mostraron resultados prometedores, pero los datos no eran concluyentes (<2 ECA con bajo riesgo de sesgo). No está claro si el tratamiento con agonistas opioides debe mantenerse o disminuirse y qué fármaco debe prescribirse para la terapia de sustitución de opioides (metadona o buprenorfina/naloxona). El mindfulness y la terapia cognitivo-conductual tienen un efecto discreto en la mejora del afecto negativo, pero no del dolor. El enfoque terapéutico podría individualizarse sobre la base de una toma de decisiones conjunta.

The relevance of patterns of use: A survey to assess cannabis use related harm. / La importancia de los patrones de consumo: Diseño de una encuesta que permita evaluar daño relacionado al consumo de cannabis.

Lifetime prevalence of cannabis use is estimated 192 million adults worldwide (2017) and has increased by 16% in the last decade. However, data on quantity and frequency of use that can lead to harm is lacking. We have developed a survey to assess patterns of cannabis use and related harms in a sample of cannabis users. This paper focuses on evaluating the feasibility of the survey and the users' satisfaction in a pilot sample. Forty cannabis users were recruited (>18 years old, living in Spain, cannabis use at least once during the last 12 months) between December 2018 and January 2019. Participants answered an online survey (mental health, organic harm and injury) and an ad hoc questionnaire to assess accessibility, feasibility, satisfaction, design and content appropriateness. Of the participants, 93.23% (n = 37.3) were satisfied with the design, 94.92% (n = 38.2) were satisfied with the content, and 94.73% (n = 37.0) were satisfied with the accessibility of the survey; only minor changes were required to improve feasibility and accessibility. Participants used a median of 1.0 Standard Joint Unit per day (Interquartile Range [IQR] 1.0-2.0). Of the sample, 92.5% reported at least one related harm and suffers a median of 4.0 disorders (IQR, 1.25-5.0). The present study allows for designing a feasible online survey to conduct a cross-sectional study with a larger sample.

Globalmente, 192 millones de adultos han consumido cannabis alguna vez en su vida (2017), un consumo que se ha incrementado en un 16% en la última década. Sin embargo, seguimos sin tener información clara sobre qué cantidad y qué frecuencia de consumo va a causar daño. Por tanto, este proyecto desarrolla una encuesta para evaluar los patrones de consumo de cannabis y los daños relacionados en una muestra de consumidores. Este artículo se centra en mostrar la factibilidad de la encuesta y la satisfacción de los usuarios en una muestra piloto. Cuarenta usuarios de cannabis fueron reclutados (>18 años, viviendo en España, consumo de cannabis mínimo una vez en los últimos 12 meses) entre diciembre de 2018 y enero de 2019. Los participantes respondieron una encuesta en línea (consumo cannábico, salud mental, organicidad y lesiones) y un cuestionario ad hoc para evaluar la accesibilidad, factibilidad, satisfacción, diseño y contenido. El 93,23% de participantes estaba satisfecho con el diseño; el 94,92% estaba satisfecho con el contenido y el 94,73% estaba satisfecho con la accesibilidad de la encuesta, y fueron necesarios solo cambios menores para mejorar la factibilidad y la accesibilidad de algunos ítems. Los participantes consumieron una mediana de 1,0 Unidades de Porro Estándar por día (Rango Intercuartílico [RIQ] 1,0-2,0). El 92,5% de la muestra puntuó como mínimo en un daño relacionado y con una mediana de 4,0 patologías (RIQ 1,25-5,0). El presente estudio nos permite diseñar una encuesta en línea con determinada factibilidad que pueda ser usada en un estudio transversal a gran escala.

Rehabilitation Gaming System for Alcohol-Related Cognitive Impairment: A Pilot Usability Study.

AIMS: Cognitive impairment in patients with alcohol use disorder (AUD) is highly prevalent, and it negatively impacts treatment outcome. However, this condition is neither systematically assessed nor treated. Thus, we aimed to explore the usability of a virtual reality-based protocol ('Rehabilitation Gaming System', RGS) for patients with AUD. METHODS: Twenty AUD patients (50% also cognitive impairment) underwent a single session of the RGS protocol (four cognitive training tasks, 10 minutes each). System Usability Scale (SUS) and Post-Study System Usability Questionnaire (PSSUQ) were applied to assess the RGS usability and patients' satisfaction with it. Also, the Perceived Competence Scale was administered to assess the patients' feelings of competence when using the training protocol. Comparisons of the responses to these questionnaires were performed between AUD patients with cognitive impairment and those without cognitive impairment. RESULTS: RGS usability was very positively rated (median SUS score = 80, Interquartile Range, IQR = 68.13-86-88). No significant differences were found in the median SUS scores for any of the sociodemographic or clinical variables, excepting for gender (women median score = 85; IQR = 80-94.38 vs. men median score = 71.25; IQR = 61.25-89.25; P-value = 0.035). The quality of the information provided by the RGS training scenarios and the usability were positively rated (PSSUQ), and patients experienced high feelings of competence. CONCLUSIONS: The RGS has been found to be usable in the short term and patients with AUD stated to be satisfied with it. Future larger, randomized trials are needed to explore the effectiveness of this tool to help overcome the cognitive deficits in AUD patients.

Primary care provider expectations of addiction services and patients in Spain.

BACKGROUND: Primary care (PC) is crucial in the care of substance use disorder (SUD) patients. However, the relationship between PC and addiction settings is complex and collaboration issues stand out. Available evidence suggests that integration of SUD and PC services can improve physical and mental health of SUD patients and reduce health expenses. OBJECTIVE: To explore the experiences, views and attitudes of PC professionals towards the interaction between PC and SUD services. METHODS: Twenty-seven GPs took part in three focus groups. The focus group sessions were audio-taped, transcribed verbatim and analysed using reflexive thematic analysis. Recurrent themes were identified. RESULTS: Four main themes were devised: (1) Differences and specificities of SUD patients, (2) Interaction between providers of PC and addiction services, (3) Patient management (4) Addiction stigma. These main themes reflect the consideration that SUD patients are a specific group with specific care needs that yield specific challenges to GPs themselves. Improved training, availability of a shared medical record system, increased feedback between GP and addiction specialists and the efficiency of the circuit are to be considered the main priority for the majority of the participants. CONCLUSIONS: An efficient and effective referral circuit, with increased feedback and shared medical records is considered key to GPs. Its implementation should keep in mind the specific features of both SUD patients and GPs.

Impact of Training and Municipal Support on Primary Health Care-Based Measurement of Alcohol Consumption in Three Latin American Countries: 5-Month Outcome Results of the Quasi-experimental Randomized SCALA Trial.

PURPOSE: We aimed to test the effects of providing municipal support and training to primary health care providers compared to both training alone and to care as usual on the proportion of adult patients having their alcohol consumption measured. METHODS: We undertook a quasi-experimental study reporting on a 5-month implementation period in 58 primary health care centres from municipal areas within Bogotá (Colombia), Mexico City (Mexico), and Lima (Peru). Within the municipal areas, units were randomized to four arms: (1) care as usual (control); (2) training alone; (3) training and municipal support, designed specifically for the study, using a less intensive clinical and training package; and (4) training and municipal support, designed specifically for the study, using a more intense clinical and training package. The primary outcome was the cumulative proportion of consulting adult patients out of the population registered within the centre whose alcohol consumption was measured (coverage). RESULTS: The combination of municipal support and training did not result in higher coverage than training alone (incidence rate ratio (IRR) = 1.0, 95% CI = 0.6 to 0.8). Training alone resulted in higher coverage than no training (IRR = 9.8, 95% CI = 4.1 to 24.7). Coverage did not differ by intensity of the clinical and training package (coefficient = 0.8, 95% CI 0.4 to 1.5). CONCLUSIONS: Training of providers is key to increasing coverage of alcohol measurement amongst primary health care patients. Although municipal support provided no added value, it is too early to conclude this finding, since full implementation was shortened due to COVID-19 restrictions.

Abstinence Among Alcohol Use Disorder Patients During the COVID-19 Pandemic: Insights From Spain.

BACKGROUND: Patients with alcohol use disorder (AUD) are likely to suffer disproportionate harms related to the COVID-19 pandemic and related policy measures. While many surveys have been conducted, most are focused on drinking changes in the general population and validation with biological markers is lacking. METHOD: We performed a retrospective cohort study among patients with AUD attending a urine drug screening program. With mixed-effects logistic regression models, we assessed the probability of screening positive for ethyl glucuronide according to patients' main clinical characteristics and time of analysis (either prior to or after a lockdown was implemented in Spain). RESULTS: A total of 362 patients provided 2,040 urine samples (1,295 prior to lockdown, 745 during lockdown). The mean age of participants was 52.0 years (SD 12.6), and 69.2% were men. Of the 43% of patients tested for other drugs 22% screened positive. After adjusting for all covariates, the odds of screening positive for ethyl glucuronide during lockdown almost doubled (OR = 1.99, 95% CI 1.20 to 3.33, p = 0.008). Other significant covariates included testing positive for other drugs (OR = 10.79, 95% CI 4.60 to 26.97) and length of treatment (OR = 0.59, 95% CI 0.47 to 0.74). CONCLUSIONS: Our data support an association between the lockdown due to COVID-19 and increased alcohol use in patients with AUD. Thus, addiction healthcare systems could face significant challenges ahead. In light of these findings, it is essential to evaluate prospectively how patients with AUD are affected by the pandemic and how health systems respond to their needs.

Baseline severity and the prediction of placebo response in clinical trials for alcohol dependence: A meta-regression analysis to develop an enrichment strategy.

BACKGROUND: There is considerable unexplained variability in alcohol abstinence rates (AR) in the placebo groups of randomized controlled trials (RCTs) for alcohol dependence (AD). This is of particular interest because placebo responses correlate negatively with treatment effect size. Recent evidence suggests that the placebo response is lower in very heavy drinkers who show no "spontaneous improvement" prior to treatment initiation (high-severity population) than in a mild-severity population and in studies with longer treatment duration. We systematically investigated the relationship between population severity, treatment duration, and the placebo response in AR to inform a strategy aimed at reducing the placebo response and thereby increasing assay sensitivity in RCTs for AD. METHODS: We conducted a systematic literature review on placebo-controlled RCTs for AD.We assigned retained RCTs to high- or mild-severity groups of studies based on baseline drinking risk levels and abstinence duration before treatment initiation. We tested the effects of population severity and treatment duration on the placebo response in AR using meta-regression analysis. RESULTS: Among the 19 retained RCTs (comprising 1996 placebo-treated patients), 11 trials were high-severity and 8 were mild-severity RCTs. The between-study variability in AR was lower in the high-severity than in the mild-severity studies (interquartile range: 7.4% vs. 20.9%). The AR in placebo groups was dependent on population severity (p = 0.004) and treatment duration (p = 0.017) and was lower in the high-severity studies (16.8% at 3 months) than the mild-severity studies (36.7% at 3 months). CONCLUSIONS: Pharmacological RCTs for AD should select high-severity patients to decrease the magnitude and variability in the placebo effect and and improve the efficiency of drug development efforts for AD.

Motivational Interviewing for Cannabis Use Disorders: A Systematic Review and Meta-Analysis.

BACKGROUND: Cannabis is one of the most used drugs worldwide. There is no gold standard treatment for cannabis use disorder (CUD). Motivational interviewing (MI) has shown efficacy in some substance use disorders. Therefore, a systematic review was conducted to assess the effectiveness of MI in CUD. METHODS: Randomized controlled trials or open-label studies published until September 2019 from 3 different databases (Pubmed, Scopus, and PsycINFO) were included, following the PRISMA guidelines and a predetermined set of criteria for article selection. Meta-analyses were conducted. The end point was determined as month 3, and 4 outcomes were analysed (abstinence rates, reduction in frequency of use, reduction in quantity of use, and reduction in cannabis use disorder symptoms) in 2 populations (adolescents and adults). RESULTS: Forty studies were identified, of which 24 were performed in adults and 16 in adolescents. MI showed efficacy in achieving abstinence in both adults (odds ratio [OR] = 3.84, 95% confidence interval [CI] 2.40-6.16, p < 0.0001) and adolescents (OR = 2.02, 95% CI 1.42-2.89, p < 0.0001). MI showed efficacy in reducing frequency and quantity of use in adults but not in adolescents. Those adults who were in the MI group consumed less joints per day than those in the control group (mean difference = -0.69 joints per day, 95% CI -0.84 to -0.53, p < 0.001), and they consumed on less days per month (mean difference = -3.9 days per month, 95% CI -7.47 to -0.34, p = 0.0317) than those in the control group. CONCLUSIONS: MI is an effective intervention to reduce cannabis use and achieve abstinence, especially among adults and patients with no prior history of psychotic disorder. Further investigation is needed to assess the effect on CUD symptoms. MI should be included in guidelines for treating cannabis use disorder as one of the essential psychological interventions.

Factors associated with primary health care providers' alcohol screening behavior in Colombia, Mexico and Peru.

Background: Screening for unhealthy alcohol use in routine consultations can aid primary health care (PHC) providers in detecting patients with hazardous or harmful consumption and providing them with appropriate care. As part of larger trial testing strategies to improve implementation of alcohol screening in PHC, this study investigated the motivational (role security, therapeutic commitment, self-efficacy) and organizational context (leadership, work culture, resources, monitoring, community engagement) factors that were associated with the proportion of adult patients screened with AUDIT-C by PHC providers in Colombia, Mexico and Peru. Additionally, the study investigated whether the effect of the factors interacted with implementation strategies and the country. Methods: Pen-and-paper questionnaires were completed by 386 providers at the start of their study participation (79% female, Mage = 39.5, 37.6% doctors, 15.0% nurses, 9.6% psychologists, 37.8% other professional roles). They were allocated to one of four intervention arms: control group; short training only; short training in presence of municipal support; and standard (long) training in presence of municipal support. Providers documented their screening practice during the five-month implementation period. Data were collected between April 2019 and March 2020. Results: Negative binomial regression analysis found an inverse relationship of role security with the proportion of screened patients. Self-efficacy was associated with an increase in the proportion of screened patients only amongst Mexican providers. Support from leadership (formal leader in organization) was the only significant organizational context factor, but only in non-control arms. Conclusion: Higher self-efficacy is a relevant factor in settings where screening practice is already ongoing. Leadership support can enhance effects of implementation strategies.

The relationship between motivations for cannabis consumption and problematic use. / Relación entre las motivaciones para consumir y el consumo problemático de cannabis.

INTRODUCTION: Systematic screening of problematic cannabis use does not include the motivations that lead to consumption, although from a person-centered perspective this is fundamental. The present study explores the motivations for cannabis use in adults and its relationship with cannabis use patterns and problematic use. METHOD: Adult cannabis users (previous 60 days) were recruited in the province of Barcelona (n = 468). Information on their sociodemographic data, cannabis use pattern, Cannabis Abuse Screening Test (CAST) and the main motivation for use were collected. Motivations were categorized a posteriori according to the Marijuana Motives Measures (MMM). A descriptive and inferential analysis was carried out to link the motivations to sociodemographic variables, consumption pattern and probability of suffering problematic cannabis use (CAST). RESULTS: Using cannabis to heighten positive feelings (35%), out of habit (29%) and to cope with negative feelings (25%) were the most frequent motivations. In comparison to other motivations, coping is related to a greater quantity of cannabis used (4 vs 3 joints per day, p = 0.005), higher probability of problematic cannabis use (77% vs 64%, p = 0.05), and greater social vulnerability (unemployment 56% vs 37%, p = 0.001; and low educational level 14% vs 8%, p = 0.042). CONCLUSIONS: Coping as a motivation for cannabis use is present in one out of four users and is a marker of social vulnerability, greater quantity of cannabis used and higher risk of problematic use. Patient-centered care together with preventive (emotional and social education) and clinical strategies (psychotherapy) can be useful for this population at higher risk.

Introducción. El cribado sistemático del consumo problemático de cannabis no incluye las motivaciones que llevan al consumo, aunque desde una perspectiva de atención centrada en la persona, este dato sea fundamental. El presente estudio explora las motivaciones de consumo de cannabis en adultos y su relación con el patrón de consumo y consumo problemático.  Método. Consumidores adultos de cannabis (en los últimos 60 días) fueron reclutados en la provincia de Barcelona (n=468). Se pasó un cuestionario para explorar datos sociodemográficos, patrón de uso, la Cannabis Abuse Screening Test (CAST) y la motivación principal para el consumo. Los motivos de consumo se categorizaron a posteriori según la Marijuana Motives Measures (MMM). Se realizó un análisis descriptivo e inferencial para explorar la relación entre la motivación categorizada y variables sociodemográficas, patrón de consumo y puntuaciones de la CAST.Resultados. Consumir cannabis para mejorar las emociones positivas (35%), por costumbre (29%) y para afrontar emociones negativas (25%) fueron las motivaciones más frecuentes. Respecto a otras motivaciones, el "afrontamiento" se relaciona con mayor cantidad consumida (4 vs 3 porros/día, p = 0,005), mayor probabilidad de tener un consumo problemático (77% vs 64%, p = 0,05), y mayor vulnerabilidad social (desempleo 56% vs 37%, p = 0,001; y bajo nivel de estudios (14% vs 8%, p = 0,042)). Conclusiones. El afrontamiento está presente en uno de cada cuatro usuarios de cannabis, es un marcador de vulnerabilidad social y de mayor cantidad de consumo de cannabis y probabilidad de consumo problemático. Una atención centrada en la persona junto con estrategias preventivas (educación emocional y social) y clínicas (psicoterapia) pueden ser de utilidad en esta población de mayor riesgo.

"The post-COVID era": challenges in the treatment of substance use disorder (SUD) after the pandemic.

BACKGROUND: Citizens affected by substance use disorders are high-risk populations for both SARS-CoV-2 infection and COVID-19-related mortality. Relevant vulnerabilities to COVID-19 in people who suffer substance use disorders are described in previous communications. The COVID-19 pandemic offers a unique opportunity to reshape and update addiction treatment networks. MAIN BODY: Renewed treatment systems should be based on these seven pillars: (1) telemedicine and digital solutions, (2) hospitalization at home, (3) consultation-liaison psychiatric and addiction services, (4) harm-reduction facilities, (5) person-centered care, (6) promote paid work to improve quality of life in people with substance use disorders, and (7) integrated addiction care. The three "best buys" of the World Health Organization (reduce availability, increase prices, and a ban on advertising) are still valid. Additionally, new strategies must be implemented to systematically deal with (a) fake news concerning legal and illegal drugs and (b) controversial scientific information. CONCLUSION: The heroin pandemic four decades ago was the last time that addiction treatment systems were updated in many western countries. A revised and modernized addiction treatment network must include improved access to care, facilitated where appropriate by technology; more integrated care with addiction specialists supporting non-specialists; and reducing the stigma experienced by people with SUDs.

A systematic review of treatments for alcohol-related cognitive impairment: lessons from the past and gaps for future interventions.

Alcohol-related cognitive impairment (ARCI) is highly prevalent among patients with alcohol dependence. Although it negatively influences treatment outcome, this condition is underdiagnosed and undertreated. The aim of this systematic review is to investigate the existing evidence regarding both cognitive and pharmacological interventions for ARCI. We systematically reviewed PubMed, Scopus and Science direct databases up to May 2019 and followed the PRISMA guidelines. The quality of the studies was assessed using the Jadad Scale. Twenty-six studies were eligible for inclusion (14 referring to neuropsychological interventions and 12 to pharmacological treatments). Among neuropsychological interventions, computerised treatments, errorless learning and component method showed positive effects on working memory, memory measures and general cognitive function. On the other hand, thiamine, memantine and methylphenidate improved working memory, long-term memory and general cognitive function. Nevertheless, these studies have several limitations, such as small sample size, lack of replication of the results or low specificity of the interventions. Therefore, no gold-standard intervention can yet be recommended for clinical practice, and further research based on promising strategies (e.g. digital interventions, thiamine) is required.

e-INEBRIA Special Interest Group Roadmap for Best Practices for Research on Brief Digital Interventions for Problematic Alcohol and Illicit Drug Use.

There is great potential for scaling up the delivery of brief interventions for alcohol and illicit drug use, given the increasing coverage of mobile devices and technologies for digital interventions, including apps for smartphones and tablets. However, while the number of digital interventions is increasing rapidly, the involvement of brief-intervention researchers and the development of good practices has just begun. In 2018, the Special Interest Group on digital interventions of the International Network on Brief Interventions for Alcohol & Other Drugs (e-INEBRIA SIG) initiated a conversation regarding possible avenues of future research, which subsequently became a roadmap for digital interventions. This roadmap consists of points considered relevant for future research, ongoing technological developments, and their implementation across a continuum of prevention and care. Moreover, it outlines starting points for the diversification of brief digital interventions, as well as next steps for quality improvement and implementation in public health and clinical practice. The roadmap of the e-INEBRIA SIG on digital interventions is a starting point that indicates relevant next steps and provides orientation for researchers and interested practitioners with regard to the ambiguous literature and the complexity of current digital interventions.

Role of Alcohol and Drug Detection by Regular Urine Sample Testing in pre-transplant evaluation for Alcohol Liver Disease. / Papel de la detección regular de sustancias en orina en pacientes en valoración pre-transplante hepático por hepatopatía alcohólica.

Alcohol Liver Disease (ALD) is one of the most prevalent conditions leading to liver transplantation for end-stage liver disease. There is lacking evidence of regular urine screening testing (RUST) impact on survival or liver transplantation of ALD patients. The aims of this study were to compare the sensitivity of RUST, to assess its impact on survival and liver transplantation, and to evaluate factors associated with adherence to RUST. We performed a single-centered retrospective study (N = 84) with ALD candidates for liver transplantation. Demographic, biochemical and clinical variables were recorded at baseline. Adherence to RUST was evaluated during follow-up. The sensitivity of both RUST and self-reports were calculated for all drugs. Multivariable logistic and survival regression analyses were performed to explore associated factors and the impact of adherence to RUST, and positive results on survival. RUST had high sensitivity for identifying active drinkers (76.9%), smokers (78.9%) and cannabis users (83.3%). High adherence to RUST was inversely associated with mortality during follow-up. Presence of personality disorders negatively impacted (OR 0.29, CI 95% 0.08-0.97) adherence to RUST. Both RUST and self-reports should be carried out in this setting. Professionals involved in liver transplantation programs must promote adherence to RUST, primarily in patients with personality disorders.

La enfermedad hepática alcohólica (EHA) es una de las causas más frecuentes de trasplante hepático en enfermedad hepática terminal. No hay evidencia de impacto de la detección regular de sustancias en orina (DRSO) sobre la supervivencia de los pacientes con EHA. Los objetivos de este estudio fueron comparar la sensibilidad de la DRSO, evaluar su impacto en la supervivencia y en el trasplante de hígado, y evaluar el impacto de la adherencia a la DRSO. Realizamos un estudio retrospectivo (N = 84) con candidatos para trasplante de hígado por EHA. Registramos las variables demográficas, bioquímicas y clínicas al inicio del estudio. Evaluamos la adherencia a la DRSO durante el seguimiento. Calculamos la sensibilidad tanto de la DRSO como de las declaraciones de los pacientes para todas las sustancias. Realizamos análisis multivariables (regresión logística) y de supervivencia para explorar los factores asociados y el impacto de la adherencia a la DRSO, y de los resultados positivos en la DRSO sobre la supervivencia. La DRSO tuvo una alta sensibilidad para identificar bebedores activos (76,9%), fumadores (78,9%) y consumidores de cannabis (83,3%). Alta adherencia a la DRSO tuvo una asociación inversa con mortalidad durante el seguimiento. La presencia de trastornos de la personalidad tuvo un impacto negativo (RM ,29, IC 95% ,08-,97) sobre la adherencia a la DRSO. Tanto la DRSO como las declaraciones deben llevarse a cabo en este perfil de pacientes. Los profesionales que participan en programas de trasplante hepático deben promover el cumplimiento de la DRSO, principalmente en pacientes con trastornos de la personalidad.
