Early maturation and substance use across adolescence and young adulthood: A longitudinal study of Finnish twins.
2017
AbstractEarly maturation, indexed by pubertal development (PD), has been associated with earlier initiation and greater frequency of adolescent substance use, but this relationship may be biased by confounding factors and effects that change across development. Using a population-based Finnish twin sample (N = 3,632 individuals), we conducted twin modeling and multilevel structural equation modeling of the relationship between PD and substance use at ages 12–22. Shared environmental factors contributed to early PD and heavier substance use for females. Biological father absence was associated with early PD for boys but not girls, and did not account for the relationship between PD and subst…
Genetic and Environmental Influences Underlying Externalizing Behaviors, Cigarette Smoking and Illicit Drug Use Across Adolescence
2012
We investigated genetic and environmental influences common to adolescent externalizing behavior (at age 12), smoking (at age 14) and initiation of drug use (at age 17) using the FinnTwin12 cohort data. Multivariate Cholesky models were fit to data from 737 monozygotic and 722 dizygotic twin pairs. Heritability of externalizing behavior was 56%, that of smoking initiation/amount 20/32%, and initiation of drug use 27%. In the best-fitting model common environmental influences explained most of the covariance between externalizing behavior and smoking initiation (69%) and amount (77%). Covariance between smoking initiation/amount and drug use was due to additive genetic (42/22%) and common en…
Predicting patient post-detoxification engagement in 12-step groups with an extended version of the theory of planned behavior
2015
Introduction Individuals with substance use disorders can receive important abstinence-specific support in 12-step groups (TSGs). However, our understanding of key factors that influence TSG participation remains limited. This study used an extended version of the theory of planned behavior (TPB) to enhance the understanding of TSG affiliation. Methods Data were retrieved from a controlled trial of a 12-step facilitation intervention conducted on an inpatient detoxification ward in Norway (N = 140). Surveys at baseline included a TPB questionnaire. The behavioral target was to attend at least two TSG meetings per month in the 6-month follow-up period. Structural equation modeling was used t…
Treatment Needs and Service Delivery for Patients with Dual Disorders During the COVID-19 Pandemic: Findings From the WADD Survey
2021
Objective: The COVID-19 pandemic has posed a great challenge for the existing health systems. The restrictions imposed across countries on the movement of people and the realignment of health care services in response to the pandemic are likely to negatively affect the health status and delivery of mental health services to persons with dual disorders (PWDD). Methods: An online survey was conducted among mental health professionals involved in providing care to PWDD to better understand the problems encountered and identify potential solutions in providing continued treatment for PWDD during the COVID-19 pandemic. Results: The findings confirmed significant disruption in the delivery of tre…
State of Training, Clinical Services, and Research on Dual Disorders Across France, India, Israel, and Spain.
2016
This article overviews training, clinical services, and research on dual disorders across four countries: France, India, Israel, and Spain.The current dual disorders systems in each of the four countries were reviewed, with a focus on strengths and limitations of each.In France, psychiatric care occurs within the public health care system and involves little training of medical graduates for managing dual disorders. Special courses and forums for specialists have recently started to meet the growing interest of physicians in learning how to manage dual disorders. The Indian health care system grapples with a large treatment gap for mental disorders, and while some treatment services for dua…
Stability of opiates in hair fibers after exposure to cosmetic treatment.
1996
Abstract The stability of opiates in clipped natural human hair was investigated. Hair fibers were incubated with defined solutions of morphine, codeine and dihydrocodeine (pH 7.4) until saturated. Original opiate-positive hair samples collected from drug addicts also were examined. Commercially available bleaching as well as perming formulas (Poly Blonde Ultra®, Poly Lock®; Henkel, Dusseldorf, Germany) were applied in vitro to the hair strands of both groups under investigation. After these treatments, the drug concentration had decreased for both bleaching and permanent waving. In the spiked hair, only 2–18% of the starting solution could be found after bleaching. About 20–30% of the drug…
Shared genetic risk between eating disorder- and substance-use-related phenotypes: Evidence from genome-wide association studies
2020
AbstractEating disorders and substance use disorders frequently co-occur. Twin studies reveal shared genetic variance between liabilities to eating disorders and substance use, with the strongest associations between symptoms of bulimia nervosa (BN) and problem alcohol use (genetic correlation [rg], twin-based=0.23-0.53). We estimated the genetic correlation between eating disorder and substance use and disorder phenotypes using data from genome-wide association studies (GWAS). Four eating disorder phenotypes (anorexia nervosa [AN], AN with binge-eating, AN without binge-eating, and a BN factor score), and eight substance-use-related phenotypes (drinks per week, alcohol use disorder [AUD], …
Substance use, medication adherence and outcome one year following a first episode of psychosis
2016
Both substance use and poor medication adherence are associated with poor outcome in psychosis. To clarify the contributions of substance use and poor medication adherence to poor outcome in the year following a first episode of psychosis, 205 patients were evaluated for use of tobacco, alcohol, cannabis and stimulants at their psychosis onset, and in a 1-year follow-up. Data on medication adherence and symptom remission were also collected. Patients had high rates of overall substance use before (37-65%) and after psychosis onset (45-66%). 44% showed poor medication adherence and 55% did not reach remission from psychosis. Nicotine dependence and cannabis use after psychosis onset signific…
Enriched Environments for Rodents and their Interaction with Nicotine Administration
2012
An active lifestyle throughout the life cycle seems to delay cognitive aging and dementia and has also been evaluated as an intervention against addiction to cocaine and other drugs of abuse. In epidemiological studies with humans, it has proved difficult to separate the cognitive, social and physical components from other variables that influence lifestyle. Studies in animal models are useful for evaluating the impact of each of these factors and for uncovering the underlying mechanisms of the benefits of complex environments. Preclinical studies have employed the Environmental Enrichment paradigm (EE) which has been proposed as a preclinical model of positive life experiences in humans. E…
Gender differences in axis I and axis II comorbidity in patients with borderline personality disorder.
2008
<i>Background/Aims:</i> Differences in the clinical presentation of men and women with borderline personality disorder (BPD) are of potential interest for investigations into the neurobiology, genetics, natural history, and treatment response of BPD. The purpose of this study was to investigate gender differences in axis I and axis II comorbidity and in diagnostic criteria in BPD patients. <i>Methods:</i> 110 women and 49 men with BPD were assessed with the computer-based version of the Munich-Composite International Diagnostic Interview and the Structured Clinical Interview for DSM-IV Personality Disorders. Gender differences were investigated for the following outc…
