Filter by:Smokers are at higher risk of developing Erectile dysfunction (ED) independent of age and comorbidities. Sildenafil is a cytochrome p3A4 (CYP3A4) substrate used for enhancing the erectile function in males. The study purpose is to determine the effect of smoking on male sexual function based on the international index of erectile function score (IIEF) and investigate the effect of smoking (Cigarettes or marijuana) on the pharmacokinetics and pharmacodynamics of sildenafil.
This is a randomized, open-label, crossover study designed to evaluate elements of abuse liability (AL) including subjective effects, plasma nicotine uptake, and physiological measures during and following ad libitum use of the investigational products (IPs) by healthy subjects.
This proposal addresses several research priorities related to the regulatory authority of the Food and Drug Administration (FDA) Center for Tobacco Products as mandated by the Family Smoking Prevention and Tobacco Control Act. Scientific evidence supports the important role of tobacco and cigarette smoke carcinogens in the development of cancers associated with cigarette smoking. Regulation of the levels of harmful constituents in cigarette smoke is one of the tobacco control strategies that now can be employed by the FDA and may serve to reduce tobacco carcinogen exposures in those smokers who are unable or unwilling to quit smoking. Such regulation will require a valid and robust approach to the assessment of comparative toxicity and carcinogenicity among various cigarette brands. This proposal will help develop a testing approach that can produce meaningful predictions of changes in human exposure due to changes in constituent levels in cigarette smoke, and hence serve as a reliable measure for product regulation. Thus, the proposed research will generate findings and data that are directly relevant to inform the FDA's regulation of the manufacture, distribution, and marketing of tobacco products to protect public health. The human trial deals with Aims 2 and 3 of this study.
The goal of this study is to assess varenicline vs. placebo for its effect on decreasing cue reactivity in light and intermittent smokers.
This proposed research seeks to examine the behavioral and neural substrates of intranasal oxytocin compared to placebo on alcohol cue-induced alcohol and cigarette craving smokers with an alcohol use disorder (AUD). Non treatment-seeking smokers with an AUD will be recruited to participate in a between-subjects, placebo-controlled, randomized pilot functional magnetic resonance imaging (fMRI) study. Participants will undergo an fMRI scan in conjunction with an alcohol-olfactory cue-reactivity task. Secondary assessments will include alcohol and cigarette craving, alcohol and cigarette consumption, physiological measures (heart rate and blood pressure) and mood measures.
This study aims at understanding the needs and concerns of the ethnic minority in Hong Kong, including their behavior, attitudes, and experiences related to smoking and smoking cessation. Specifically, how the level of smoking-related knowledge among them differ from the rest of the Hong Kong people, will be explored. In addition, whether Hong Kong smoking policy influenced the smoking pattern of them will be investigated.
Patients with COPD who participated in the second rehabilitation program in the Pulmonary Rehabilitation unit will be included in the study. Pulmonary function tests, arterial blood gases, mMRC dyspnea perception, 6-minute walking distance, disease-specific (SGRQ) quality of life and hospital anxiety depression scale values will be compared.
The purpose of this study is to learn if a mindfulness-based smoking cessation smartphone app can help people quit smoking and stay on antiretroviral therapies.
The goal of this study is to develop and pilot test a brief intervention to increase motivation to quit and smoking cessation treatment engagement among smokers with chronic pain.
This research study aims to develop and test the effectiveness of a mobile application for patients who smoke to use while waiting in the clinic exam room to see their provider. The application will present patients with a variety of videos designed to increase their engagement in evidence-based smoking cessation treatment and offer them action steps to engage in smoking-related treatment or discussions with their provider.
