Filter by:This research is designed to assess the impact of pretreatment with puerarin (NPI-031G), a major ingredient in the plant kudzu, on alcohol drinking. Hypothesis: Short-term treatment with this compound will reduce alcohol self-administration in a simulated natural settings laboratory.
Alcohol abuse among college students is a significant and long-standing public health issue. The transition into college is marked by substantial increases in alcohol abuse and problems, suggesting the importance of interventions that take place prior to and immediately following matriculation. To date, early interventions with this population have yielded modest results with very little evidence identifying either the factors that are responsible for observed effects or specific individual or situational factors that qualify intervention efficacy. There is preliminary evidence for the efficacy of individualized feedback (IF) in reducing college student alcohol abuse. Additionally, a sizeable body of research with early adolescents and emerging work with college students point to the utility of parent-based interventions (PBI). The major aim of this research is to provide the first test of the unique and combined efficacy of these two successful interventions in reducing alcohol abuse among matriculating college students.
The goal of this project is to adapt a computerized Screening and Brief Advice (SBA) protocol that has demonstrated efficacy in reducing underage drinking among adolescent primary care patients and then to test it in a multi-site randomized controlled trial (RCT).
To monitor the inhibition of 5a-reductase (5AR) enzyme activity at 1, 3, 7, 14, 21, 28 and 42 days following administration of a single dose of dutasteride (2, 3, or 4 mg) by measuring the change in blood levels of 3a-androstanediol glucuronide (3a-diolG) and the ratio of dihydrotestosterone (DHT) to testosterone. To accomplish this aim, an open-label, between-subjects dose comparison study design will be employed with subjects receiving a 2, 3, or 4 mg dosage. Subjects (up to n=40 enrolled to allow a minimum of 24 completers) will be randomly assigned to one of the 3 dose levels. Results of this study will inform the dose selection for a subsequent placebo-controlled, within-subject, crossover study of dutasteride on the effects of alcohol. A secondary aim of this study is to examine the correlation of a genetic variation in the type I 5AR gene and baseline DHT/T ratio and effect of dutasteride at day 3. A variation in this gene which is one of the targets of dutasteride has been reported to be associated with higher baseline levels of DHT.
Aggressive behavior, both in the form of violence toward others (injury-inflicting or homicide) or toward oneself (suicide or self-injures) create problems of patient management, treatment and paroles. Biological causes of violent crime were hypothesized by Eysenck (1978), who believed that criminality resulted from a nervous system distinct from that of most people. The prefrontal cortex, regulates planning of motor acts and executive functions, which are critical for inhibitory ability and control of impulsive outburst were found to be impaired in violent subjects (Hoaken et al, 2003; Blair, 2001; Brower and Price, 2001; Filley et al, 2001; Raine et al, 2000; George et al, 2004; Dolan and Park, 2002; Stevens et al, 2003; Raine and Yang, 2006), especially in impulsive offenders murderers (Raine et al, 1997; 1998). Violence act influenced by nonplaning outboards definite as impulsive aggression (Linnoila and Charney, 1999), which one of the most important factor influenced by dangerous behavior in general (for review: Skodol, 1998, Moeller et al, 2001; Pontius, 2000; 2004; Siever, 2008). Cholesterol and fats have many roles and may influence brain function and behavior through modification of membranes; myelin; enzyme function; absorption and transport of fat-soluble vitamins and toxins; and steroid hormones and through effects on production, reuptake, or metabolism of neurotransmitters (Boston et al, 1996). Since 80-th a strong association was found between low cholesterol levels and violent behavior, an association that was not due to age, race, sex, or diagnosis (Mufti et al, 1998; New et al, 1999; Alvarez et al, 2000; Golomb et al, 2000; Hillbrand et al, 2000; Troisi and D'Argenio, 2006; Chakrabarat and Sinha, 2006). Associations between violent behavior, cognitive functioning and total cholesterol level were contradicted with difference in samples and behavioral parameters: homicide, homicide attempts, rape, physical or verbal aggression, complete suicide or suicide attempts, only partially accounted for each measure of behaviors, suggesting that further investigation is warranted. Because of the inconsistencies in the available data, we studied retrospectively a group of criminal offenders with alcohol and drug use. Our analysis of lipid constituents in serum focused on TC, HDL, LDL, and TG. Significance of the study. It is possible that cholesterol profile is a biomarker and potential predictor of violent in patients with polydrug use. The purpose of this retrospective study is to investigate the correlations between cholesterol and cognitive profiles in psychiatric patients with violent behaviour. The demographic and criminal records, clinical characteristics, cholesterol profiles, and cognitive performance data of these patients will be will be intercorrelated.
This study will determine whether a cognitive behavioral intervention that demonstrates strong evidence in the U.S. of reducing alcohol use is effective when delivered by paraprofessionals in Kenya and compared against a usual care support group.
Several personality factors have been shown to be associated with risk for alcohol and substance misuse, and differentiate substance abusers based on clinical profile, treatment response and susceptibility to other forms of mental illness. Personality-targeted interventions have been found to have significant preventative effects on onset and growth of drinking, binge-drinking and drinking problems in adolescents attending mainstream schools (Conrod, Castellanos & Mackie, 2008). The interventions concurrently reduced personality-specific emotional and behavioural problems (Castellanos & Conrod, 2006), and prevented the onset and escalation of drug-use over a two-year period (Conrod, Castellanos-Ryan & Strang, 2010). This cluster randomised controlled trial aims to examine whether these results can be replicated when interventions are delivered by trained educational professionals. In addition, the trial will evaluate the broader impact of the programme on cigarette smoking, school attendance, academic achievement and school-wide behaviours.
The purpose of the study is to determine whether a web-based ultra-brief intervention, consisting of personalized normative feedback or standardized self-help material, is effective in lowering self reported alcohol use in heavy drinkers.
Purpose of the study: This is a pilot randomized controlled trial to identify methods of involving underage youth in interventions to reduce alcohol use through the primary health care system. The trial will compare the effectiveness of using an onsite behavioral health specialist for screening, intervention and referral with basic written information and staff recommendations typically provided in primary care offices.
This study will explore the hypothesis that effects of alcohol are in part mediated by increased production of neuroactive steroids, which interact with GABAA-receptors. We propose to study non-dependent drinkers using a 4-session within-subjects design in which alcohol / placebo is paired with dutasteride / placebo pretreatment. Dutasteride is a 5-alpha steroid reductase (5AR) inhibitor that limits the production of dihydrotestosterone and the 5a-reduced neuroactive steroids allopregnanolone, pregnanolone and 3a,5a-androstanediol.
