Filter by:Moderate alcohol consumption is associated with a decreased risk of diabetes type 2. This association could be mediated by an improvement of insulin sensitivity with moderate alcohol consumption. Patients with diabetes type 2 or impaired glucose tolerance often may have decreased fat oxidative capacity or oxidative phosphorylation in tissue such as muscle. This could lead to accumulation triglyceride storage in muscle, which could interfere with insulin signaling. Whether such mechanism can also play a role with moderate alcohol consumption is unknown and will be investigated in this study. In addition, moderate alcohol consumption with a meal can lead to delayed hypoglycemia in type 1 diabetes patients. How moderate alcohol consumption affects postprandial glycemic response in healthy subjects is unknown. This is a secondary objective of this trial.
Aim of the project is to validate and functionally characterize the combined impact of candidate genes and stress exposure on drinking in adolescents. Lifetime and recent stress experiences and drinking are recorded in a sample of healthy young adults who are genotyped for polymorphisms in candidate genes related to alcoholism. All participants undergo a standard laboratory psychosocial stress test. Our hypothesis is that specific genes can be identified which influence drinking by modulating stress response.
The aim of the study is to test whether or not a tailored multi-component intervention program to increase the activity of general practice teams in the prevention of hazardous and harmful alcohol consumption results in increase advice giving rate to patient with hazardous and harmful alcohol consumption and a better patient outcome in terms of hazardous and harmful alcohol consumption. The primary objectives of the proposed study are: 1. to test the (cost) effectiveness of a tailored multi-component implementation program to engage general practices (i.e. GPs, nurse practitioners or practice nurses/assistants) in the prevention of hazardous or harmful alcohol consumption, changing both providers' advice giving behaviour and patients' alcohol consumption 2. to identify predictors of effect 3. to examine whether or not the implementation of a tailored multi-component implementation program to engage general practice in the prevention of hazardous or harmful alcohol consumption is feasible.
Over the past decade, many new programs intended to prevent substance use among adolescents have been developed and evaluated. There has been a recent shift towards brief interventions for youth in school (Brown, 2001; D'Amico and Fromme, 2002) and health care settings, such as emergency rooms and inpatient clinics (Barnett et al., 2001; Colby et al., 1998; Monti et al., 1999). Although the primary care setting presents a unique opportunity to intervene with youth concerning drug use, such as marijuana or inhalants, many youth are not screened for use (Friedman et al., 1990; Johnson and Millstein, 2003; Middleman et al., 1995) and preventive services in this setting are significantly below recommended levels (Halpern-Felsher et al., 2000; Klein et al., 2001; Ozer et al., 2001). The objectives of the proposed research are to: 1) explore the feasibility of adapting a brief intervention from our previous work for use in the primary care (PC) setting, and 2) assess the short-term efficacy of the intervention in the PC setting. During year 1, focus groups of high-risk youth (n=16), parents (n=8), and providers (n=8) will provide feedback on barriers to implementing a substance use brief intervention in a PC setting. We define high-risk youth as those who may have already developed regular patterns of use or have experienced some problems due to their use. In addition, the intervention will be pilot tested with 10 high-risk youth who will provide feedback on intervention content. Revisions will be made to the intervention curriculum based on this feedback and in year 2, the short-term efficacy of the intervention will be tested with a small sample of high-risk youth (n=30). This study will extend brief intervention research for youth, as it will be one of the first to examine the feasibility of implementing a brief substance use intervention to PC with high-risk youth and to determine the impact of this intervention on short-term outcomes.
This project is designed to compare college drinking interventions on outcomes and cost-effectiveness. We plan to recruit 700 students with residence hall alcohol violations to participate in a randomized study to evaluate 3 brief interventions: in-person brief motivational intervention, Alcohol 101plus (an interactive CD-ROM program), and AlcoholEdu (a Web-based tutorial). Participants will be followed over 12 months to determine changes in alcohol consumption and related problems. We will also explore which participants might respond better to one intervention vs the others.
Moderate alcohol consumption is associated with a decreased risk of cardiovascular disease and type 2 diabetes. The association of alcohol consumption with cardiovascular disease is mediated by a functional polymorphism of alcohol dehydrogenase 1c, but the effect of this polymorphism on alcohol metabolism is only investigated in vitro. The risk reduction of moderate alcohol consumption for cardiovascular disease is explained largely by an increase of HDL cholesterol, but an increase of adiponectin concentrations after moderate alcohol consumption may also be involved. It seems likely that adiponectin is a mediator for the association of moderate alcohol consumption with type 2 diabetes. The mechanism by which moderate alcohol consumption increases adiponectin concentrations is unknown, but ppar-gamma activation may be involved. effects of this polymorphism on mediators of this relation are not known. This study therefore investigates the effect of moderate alcohol consumption and the influence of alcohol dehydrogenase 1c polymorphism on ppar-gamma activated gene expression and risk factors of cardiovascular disease and type 2 diabetes.
This study evaluates multi-attribute utility, a modification of subjective expected utility, as a descriptive model of the adolescent's decision to initiate smoking or alcohol use. According to the model, the young decision maker envisions a set of consequences that will follow the two decision options, either to continue as a non-user or to initiate usage. Each consequence has three components. The components are the worth of the consequence, which may be positive or negative, the judged likelihood that the consequence will happen, and the importance of the consequence. Within an individual, importances will change with mood or circumstance, which is how the model accounts for impulsive decisions that may occur in social settings. The model will be tested by eliciting components of ten independent consequences from a large group of students early in the seventh-grade year. Current usage will also be examined; extant data suggest that most students will be non-users at that time. It is known that a fair amount of initiation takes place during the seventh and eighth grade years. The hypothesis is that those non-users whose model scores are high will be more likely to initiate usage than those whose scores are low. The same students will be queried regarding usage eighteen months later to evaluate the hypothesis. It is now well known that differential knowledge regarding the harmful effects of drug use does not distinguish adolescent users from non-users. The model approach quantifies the idea that anticipated positive consequences play a prominent role in the decision of those who choose to initiate. An important implication is that prevention campaigns might profit by addressing positive as well as negative consequences of usage.
The purpose of this study is to examine drinking behavior and decision-making while taking Naltrexone and placebo. This is a double-blind, randomized, placebo-controlled crossover study. There are two cycles: one cycle on Naltrexone and one cycle on placebo.
The purpose of this study is to examine the efficacy of a brief motivational intervention for alcohol use in incarcerated women.
The study evaluated the effectiveness of a mail-based self-guided motivational intervention based on Project CHOICES to reduce alcohol-exposed pregnancies (AEP) with female students and non-students 18 to 44 years of age living in Florida. The investigators hypothesize that the motivational intervention will significantly reduce more women's risk of an AEP than will an informational intervention aimed at preventing fetal alcohol syndrome.
