The effects of acceptance and commitment therapy on eating behavior and diet delivered through face-to-face contact and a mobile app: a randomized co…

2018

Background Internal motivation and good psychological capabilities are important factors in successful eating-related behavior change. Thus, we investigated whether general acceptance and commitment therapy (ACT) affects reported eating behavior and diet quality and whether baseline perceived stress moderates the intervention effects. Methods Secondary analysis of unblinded randomized controlled trial in three Finnish cities. Working-aged adults with psychological distress and overweight or obesity in three parallel groups: (1) ACT-based Face-to-face (n = 70; six group sessions led by a psychologist), (2) ACT-based Mobile (n = 78; one group session and mobile app), and (3) Control (n = 71; …

Eating disorders (EDs) are characterized by marked cognitive distortions and maladaptive schemas. Cognitive models of EDs highlight the direct impact of cognitive dysfunctions on eating-related disturbances, insofar as specific cognitive contents such as thoughts about diet rules and food or loss of control may trigger disturbed eating behavior. Moreover, early maladaptive schemas that reflect perfectionist standards and relate to achievement and performance seem to be associated with disturbed eating, e.g., via their impact on situation-specific appraisals. However, so far, no study has investigated these assumptions. Hence, the present study sought to demonstrate whether and how cognitive…

Neuroimagen y adicción I: Correlatos neuroanatómicos y funcionales de la administración aguda, el craving y el consumo crónico de psicoestimulantes

2007

En los últimos años ha aumentado el interés por el estudio de los correlatos neurobiológicos del consumo de drogas psicoestimulantes, como la cocaína o el éxtasis. La aplicación de las técnicas de neuroimagen ha permitido examinar in vivo los efectos agudos de la administración de estas sustancias, los correlatos cerebrales del deseo intenso por consumirlas (craving), o las alteraciones funcionales o morfológicas asociadas al consumo crónico. Los objetivos de esta revisión son: (1) explicar brevemente las técnicas de neuroimagen utilizadas en la investigación de drogodependencias (2) presentar los hallazgos más actualizados de neuroimagen en el estudio de los correlatos cerebrales del consu…

Neuroimagen y adicción II: Correlatos neuroanatómicos y funcionales de la administración aguda, el craving y el consumo crónico de opiáceos, alcohol …

2008

En las últimas décadas las técnicas de neuroimagen han contribuido en gran medida al estudio in vivo de los efectos neurobiológicos del consumo agudo y crónico de sustancias de abuso. El incremento en los últimos años del consumo de alcohol y cannabis, así como las graves consecuencias asociadas al consumo de opiáceos han contribuido al aumento del interés por estudiar los efectos de estas sustancias en el sistema nervioso central. Los objetivos de esta revisión son: (1) presentar los hallazgos más actualizados de neuroimagen en el estudio de los correlatos cerebrales del consumo de opiáceos, alcohol y cannabis, teniendo en cuenta: (i) la administración aguda de estas sustancias, (ii) el cr…

Chronic alcohol intake abolishes the relationship between dopamine synthesis capacity and learning signals in ventral striatum

2014

Drugs of abuse elicit dopamine release in the ventral striatum, possibly biasing dopamine-driven reinforcement learning towards drug-related reward at the expense of non-drug-related reward. Indeed, in alcohol-dependent patients, reactivity in dopaminergic target areas is shifted from non-drug-related stimuli towards drug-related stimuli. Such 'hijacked' dopamine signals may impair flexible learning from non-drug-related rewards, and thus promote craving for the drug of abuse. Here, we used functional magnetic resonance imaging to measure ventral striatal activation by reward prediction errors (RPEs) during a probabilistic reversal learning task in recently detoxified alcohol-dependent pati…

Therapeutic Drug Monitoring of Naltrexone and 6β-Naltrexol During Anti-craving Treatment in Alcohol Dependence: Reference Ranges.

2018

Aims Aim of this study was to associate concentration of naltrexone and its major active metabolite 6β-naltrexol in blood with therapeutic outcome during treatment with naltrexone in subjects with alcohol dependence. Treatment with the μ-opiate receptor antagonist naltrexone has been shown to reduce craving for alcohol and alcohol intake in patients suffering from alcohol dependence. Short summary This article shows the use of therapeutic drug monitoring in alcohol dependent patients, who are treated with naltrexone. The plasma concentrations of naltrexone and 6β-naltrexol showed high inter-individual variability. They were predictive for treatment response, as they correlated significantly…

Cue exposure in alcohol dependent patients: preliminary evidence for different types of cue reactivity.

2000

Craving is considered to be an important phenomenon in addictive behaviours. However, there is still an unresolved debate on what craving for alcohol means, how it is best measured and which clinical and therapeutical consequences its presence or absence may imply. Cue reactivity paradigms have been developed to elicit craving under standardized experimental conditions. Here we present preliminary results characterizing alcohol-dependent patients with regard to subjective and psychophysiological aspects of exposure to alcohol-associated cues in a cue reactivity paradigm. Thirty-six patients fulfilling at least 5 criteria of alcohol dependence according to DSM-IV criteria were studied after …

Altered Food Behavior and Cancer: A Systematic Review of the Literature

2022

There is evidence of an association between cancer and certain types of altered eating behaviors, including orthorexia, food cravings, and food addiction. Given the growing interest in the topic throughout the scientific community we conducted a systematic review to summarize current evidence on the development of altered food behavior, including food addiction and cancer. The Cochrane Collaboration and the Meta-analysis Of Observational Studies in Epidemiology guidelines were followed to perform this systematic review. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used to report the process and results. The structured literature search was co…

Effect of adolescent exposure to WIN 55212-2 on the acquisition and reinstatement of MDMA-induced conditioned place preference.

2009

The present study employs a conditioned place preference procedure (CPP) to examine the effects of exposure to the cannabinoid agonist WIN 55212-2 (WIN) (0.1 and 0.5mg/kg) during adolescence on the reinforcing properties of +/-3,4-methylenedioxymetamphetamine hydrochloride (MDMA) (1.25 and 2.5mg/kg) in mice. On postnatal day (PD) 27, animals received a daily injection of the assigned treatment on 5 consecutive days, and three days later the place conditioning procedure was initiated (PD 35). The results suggest that pre-exposure to cannabinoids strengthens the properties of MDMA and favors reinstatement of the craving for the drug, which endorses the gateway hypothesis.

Exercise as an Adjuvant Intervention in Opiate Dependence

2013

We read with interest the article by Weinstock et al. in whichthe authors propose exercise as an adjuvant intervention inopiate agonist treatment based on current research findings(1).The use of an opiate agonist, such as buprenorphine, butmainly, methadone, for the treatment of opiate dependenceis currently an effective therapy for this type of addiction.The main benefits of this treatment occur through a relieffrom craving narcotic drugs, a temporally suppression ofwithdrawal symptoms, and by blocking the euphoric effectsof opiates (2). Unfortunately, patients needing treatment foropiatedependenceoftenfaceavarietyofco-occurringissues,suchashepatitisBandCvirusesorhumanimmunodeficiencyvirus (H…
