This study examined the effects of the nicotine patch on craving and withdrawal symptoms, safety, and compliance among adolescents. The secondary goal was to conduct a preliminary investigation of the effectiveness of the nicotine patch in helping adolescents quit smoking. The study design was a double-blind, placebo-controlled, randomized trial of the(More)
The accurate assessment of both tobacco withdrawal and the impact of the nicotine patch on withdrawal may be compromised by attrition of subjects, or by subjects smoking during withdrawal. To reduce these occurrences, 211 participants were provided with intensive cessation counseling while trying to quit smoking with either nicotine (21 mg) or placebo(More)
AIMS To examine the effects of reduced nicotine cigarettes on smoking behavior, toxicant exposure, dependence and abstinence. DESIGN Randomized, parallel arm, semi-blinded study. Setting University of Minnesota Tobacco Use Research Center. INTERVENTIONS Six weeks of: (i) 0.05 mg nicotine yield cigarettes; (ii) 0.3 mg nicotine yield cigarettes; or (iii)(More)
This study employs a rigorous inpatient laboratory setting to test the hypothesis that withdrawal symptomatology in short-term smoking cessation in women is increased in the late luteal phase when pre-menstrual symptomatology is the highest. Twenty-one female smokers with clinical, anatomical, and hormonal verification of their menstrual cycle phase were(More)
Rates of smoking relapse remain high, despite the wide availability of cessation aids. Presumably factors such as craving, withdrawal symptoms, and smoking urges are key contributors to relapse, but empirical support for this presumption is not conclusive and is complicated by the high variability in symptoms across individuals and time, as well as by the(More)
Gender differences in nicotine response with regard to nicotine sensitivity and withdrawal symptomatology have been reported, with the suggestion that ovarian hormones play a role. Few studies, however, have directly assessed hormonal influences on nicotine response. This study focused on the effects of a transdermal nicotine patch in women during acute(More)
This study extends our understanding of smoking behavior, withdrawal, and premenstrual symptomatology in smoking women, as well as energy intake as a function of cycle phase. Thirty-two women age 18 to 40 years, smoking ad lib, were followed for an average of two menstrual cycles with hormonal verification. Withdrawal and premenstrual symptomatology as well(More)
AIMS To examine if menstrual phase affects relapse in women attempting to quit smoking. DESIGN An intent-to-treat randomized smoking cessation trial where women were assigned to quit smoking in either the follicular (F) or luteal (L) menstrual phase and were followed for up to 26 weeks. They were assessed for relapse by days to relapse and relapse phase(More)
BACKGROUND Humoral-mediated as well as cell-mediated immunity is compromised in myeloma patients receiving treatment. Immunocompromised patients are at risk of developing herpes zoster. There is evidence from clinical trials that bortezomib therapy is associated with a significant risk of herpes zoster. It is the authors' clinical policy to administer(More)
STUDY OBJECTIVES To assess the effect of continued smoking and smoking reduction on cardiovascular biomarkers (eg, WBC count, cholesterol concentrations, BP, heart rate). DESIGN, SETTING, AND PARTICIPANTS This study, conducted at the University of Minnesota, randomized smokers interested in significantly reducing cigarette use but not quitting to either(More)
