Filter by:The team's ultimate goal is to improve health care quality and effectiveness and support patient-centered care. In this project, we, the investigators, will test whether providing patients with guideline based-recommendations regarding tobacco use, physical activity and mental and physical health-related quality of life (patient reported measures: PRMs) using health information technology increases doctor-patient discussions regarding these topics and results in improvements in PRMs. We will randomize physicians in a single general internal medicine practice. Patients seeing intervention physicians will receive guideline-based recommendations regarding PRMs, those seeing control physicians will not. We will compare differences in doctor-patient discussions regarding PRMs between the intervention and control groups. The successful completion of this project will provide evidence the effectiveness of involving patients in their care through the use guideline-based feedback.
The purpose of this study is to determine if an assessment protocol that measures the need for support with smoking cessation and that will be administered by primary health care nurses helps patients with obstructive pulmonary disease (COPD) quit smoking.
The purpose of this study is to determine whether subjects following a high protein diet will gain less in weight after smoking cessation compared to subjects following a low fat diet due to the effects of protein on metabolic rate and hunger.
The primary aim of this research study (STEP) is to compare the effectiveness of two smoking cessation programs that integrate counseling and nicotine replacement with either a wellness program or exercise. This will help us to determine whether different lifestyle interventions (wellness or exercise) help increase the effectiveness of current standard programs for smoking cessation.
In the present study the investigators will measure the effects of nicotine and non-nicotine factors on brain function during cognitive processes that are differentially sensitive to these factors. One process—continuous working memory (CWM)—is implemented via a network of frontal and parietal brain regions and is highly dopamine dependent. Smoking cessation results in significant deficits in CWM which can persist for weeks and are reversed by resumption of nicotine administration in the form of smoking or nicotine replacement. Additionally, CWM deficits are observed during smoking of denic cigarettes. Brain function during CWM is modulated by smoking abstinence and subsequent nicotine administration and activity in the dlPFC is implicated in these effects. Collectively, these data suggest that CWM is highly sensitive to the nicotine, but not non-nicotine components of smoking. Brain function during CWM is altered by smoking abstinence and nicotine, but the effect of smoking, in the absence of nicotine, has not been evaluated. Another process—cue-reactivity (CR)—results from the repeated pairing of otherwise neutral stimuli with nicotine administration. Acute smoking cessation has not been shown to have strong effects on CR in the form of cue-provoked craving, nor has nicotine replacement been shown to have robust effects on CR. Likewise, the direct effects of smoking abstinence on brain CR have been small; though craving has been shown to modulate relations between abstinence and CR. Moreover, recent data from our lab suggest larger 'doses' of abstinence (~ 24 hrs) may amplify brain responses to cues. The effect of smoking in the absence of nicotine, on CR has not, to our knowledge, been evaluated. Collectively, these data suggest that CR in the form of cue-induced craving is not highly sensitive to the effects of short-term smoking abstinence or nicotine. Brain CR is modulated by abstinence-induced craving and longer-term abstinence, but it is unclear whether abstinence from nicotine or non-nicotine components is responsible for these effects. In the present study, we propose to evaluate the effects of non-nicotine and nicotine factors on CWM and CR using functional magnetic resonance imaging. This method allows for the non-invasive assessment of brain function. We will also examine the role of genes in moderating and mediating the effects of nicotine and non-nicotine factors on cognitive function
The primary aim of this project is to test the effect of exercise on acute nicotine withdrawal. Acute nicotine withdrawal is characterized by a complex array of symptoms associated with increased risk of relapse among individuals attempting smoking cessation. The available remedies do not target all aspects of withdrawal. For example, pharmacologic treatments reduce withdrawal-based craving, but have no effect on cue-related craving, altered sleep, and mood disturbances during withdrawal. Therefore, non-pharmacologic behavioral techniques with the potential to attenuate persistent withdrawal symptoms are needed. We hypothesized that exercise can be a valid non-pharmacologic strategy to improve these domains.
Choices Plus, a randomized controlled study, will determine the efficacy of the Project CHOICES intervention plus a referral to an evidence-based smoking cessation program in reducing the risk of alcohol- and tobacco-exposed pregnancies.
This study will develop: 1. Develop the computer-based brief intervention and Contingency Management (CM) components, with repeated feedback from experts, prenatal clinic staff, and participants. 2. Recruit 110 pregnant women who are actively smoking, and randomly assign recruited women to Brief Intervention, CM, combined, or control conditions. 3. Conduct follow-up evaluation at 12 weeks post-intervention to measure self-reported smoking, breath carbon monoxide (CO), and urinary cotinine levels. 4. Collect data regarding birth outcomes and evaluate the feasibility of various methods of post-partum follow-up.
Bupropion and varenicline are indicated for smoking cessation. The objectives of this study are two-fold: (1) to explore the logistic feasibility of distributing bupropion and varenicline free of charge to treatment-seeking smokers in the province of Ontario, Canada and (2) to evaluate the real-world effectiveness of bupropion and varenicline treatment in Ontario compared to a no-drug comparison group. In an open label study, Ontario smokers who smoke 10 or more cigarettes per day and intend to quit smoking in the next 30 days, will enroll via the study website, visit their physician to receive a prescription for bupropion or varenicline for 12 weeks or neither if they so choose, forming the no-drug comparison group. All participants will receive weekly motivational emails for 12 weeks. Abstinence measures will be taken at 4, 8 and 12 weeks and at 6 and 12 months. The proportion of eligible participants who were able to confirm an appointment with a physician to receive the prescription will be also measured.
Smoking causes 90% of all lung cancer deaths among men and 80% of lung cancer deaths in women. Surgery is a great opportunity to help patients quit smoking. Smokers are at increased risk for heart, lung, and wound complications around the time of surgery. Even a brief abstinence from smoking can produce benefits. Surgery can also motivate smokers to quit spontaneously. If the investigators can take advantage of this great opportunity, they may be able to help many smokers quit using simple means. However, currently most smokers continue to smoke cigarette on the morning before surgery, as shown by the measurement of exhaled carbon monoxide (CO) on the morning of surgery. CO is one of the many poisons in cigarette smoke. It only stays in the body for a few hours. By asking smokers to blow into a small machine, the investigators can test the CO level in the smokers' body and thus know if they have just smoked within the past few hours. The goal of this study is to determine the role of carbon monoxide monitoring as a means to decrease cigarette smoking before surgery. The investigators will identify a group of smokers who are scheduled for surgery and invite them to participate. One or two days before surgery, half of the patients will receive a brief advice about quit smoking. The other half of patients will be told that their CO will be checked before surgery, in addition to the brief advice. On the morning of surgery, the investigators will then check their CO level to determine if they have followed the advice. In order to have a better understanding about the factors influencing patients' intent to quit smoking, the investigators will ask all study participants to fill out a questionnaire. The questionnaire is constructed according to behavioral theories which provide good framework for studying people's intent and behavior. If the investigators are successful, they will determine how much of an impact the message of CO testing has on smoking before surgery. The investigators will also gain insights into facilitators and barriers to smoking cessation around the time of surgery. The brief intervention evaluated in this study has potential to be disseminated and to promote the long term health of surgical patients.
