Filter by:Cigarette smoking during pregnancy increases risk for catastrophic pregnancy complications, growth retardation, other adverse infant health problems, and later-in-life chronic conditions. One group that is particularly at risk for these complications are Alaska Native (AN) women. Prevalence of smoking during pregnancy is disproportionally high among AN women compared to US pregnant women overall (i.e., ~36% and ~13%, respectively) and few smoking-cessation interventions have been evaluated among this population. A substantive barrier to offering evidence-based interventions to AN women is the geographic remoteness of Alaska. The most effective intervention for promoting smoking cessation during pregnancy is financial incentives in which participants earn incentives (e.g., cash) contingent on objective evidence of smoking abstinence. This intervention has been adapted to be delivered entirely through a smartphone meaning that the geographic remoteness of Alaska will not be a barrier with this intervention. Participants submit videos of themselves completing breath and saliva tests, and incentives are then delivered through the application if the tests indicate smoking abstinence. Through a collaboration between the University of Vermont and the Alaska Native Tribal Health Consortium, the goal of this study is to examine the preliminary feasibility and efficacy of this smartphone-based incentives intervention among AN women. Pregnant AN women will be recruited through ads posted on social media. Eligible participants who complete the informed consent process will be randomized to either: Best Practices or Best Practices + Incentives. In the Best Practices condition, participants will receive three brief educational sessions and a referral to the Alaska state quitline. In the Best Practices + Incentives condition, participants will receive the same education sessions and quitline referral, plus financial incentives contingent on the smartphone-based testing of breath and saliva specimens indicating abstinence from recent smoking. Outcomes will include point prevalence smoking abstinence at assessments conducted in late pregnancy and 4-, 8-, 12-, and 24-weeks postpartum, continuous abstinence during antepartum and postpartum, and perceived barriers and facilitators of treatment engagement. Overall, this project has the potential to address disparities in access to efficacious, evidence-based smoking cessation treatments among AN pregnant women.
This single arm study will assess whether smoking cessation counseling offered to chronic pain patients is effective in reducing pain and cigarette use.
This project from the University Hospital of Parma (AOUPR) aims to verify the feasibility of a prevention program in our district, relying on advanced technological resources and highly experienced team in lung cancer early diagnosis, in order to identify useful elements towards the applicability of such a prevention program on a large scale (regional, national). Uncontrolled, monocentric experimental study with dynamic enrollment and prospective data collection, aimed at implementing a prevention program based on scientific evidence. This study is set to verify the applicability and feasibility of a lung cancer prevention program in a real context, including a preliminary evaluation at the smoking cessation clinic and a LDCT assessment with subsequent LDCT follow-up for participants who show indeterminate findings at the first LDCT (LDCT baseline) exam. The main objective of the study is to verify the feasibility of a lung cancer prevention program according to internationally validated scientific methods. Secondary objectives: 1. To evaluate the use of local smoking cessation clinics and their effects in terms of smoking cessation (primary prevention) 2. To evaluate the outcomes of the program in terms of number of patients with early (presymptomatic) lung cancer treated with minimally invasive surgery (secondary prevention) 3. To evaluate the number of false positives and their diagnostic work-up (PET-CT, CT-guided biopsy, bronchoscopy) Primary endpoint: - Percentage of enrolled subjects to whom the program was offered within 60 days from the date of enrolment and percentage of those who stop smoking for at least 12 months Secondary endpoints: - To describe the organizational model, human resources employed, difficulties encountered and elements that have favoured its realization - To measure the variation in smoking habits in enrolled smokers - To describe the effect of annual LDCT on lung cancer diagnosis rates, considering size, shape, histology and site - To measure the consequent demand for further diagnostic investigations and treatment - To measure the number of false positives Subjects at high risk of lung cancer screened by the medical team of the AOUPR or by GPs to join the prevention program. Inclusion criteria - Age between 50 and 75 years - Equivalent tobacco intoxication of ≥ 15 cigarettes per day for ≥25 years or ≥ 10 cigarettes per day for ≥30 years - Status of current smoker or ex-smoker for <10 years. Exclusion criteria • Personal history of cancer within the prior 5 years We expect to recruit around 500 people in 1 year. This sample size is considered adequate based on the available resources, both human and economic. After closing and adjusting the database and before data analysis, a document called Statistical Analysis Plan (SAP) will be drawn up. It will consist of the following paragraphs: - Statistical methods planned in the study protocol; - Size of the sample; - Management of missing data; - Evaluation of the endpoints; - Statistical models that will be applied in the analysis. The socio-demographic characteristics of the enrolled subjects, the adopted organizational methods and the effects of the prevention program (endpoints) will be analyzed and described using tables and figures. The project "PRogetto Salute Parma: Primary and secondary prevention of smoking-related lung cancer" will be started once approved by the institutional Ethics Committee and authorized by the General Manager. The study is expected to be carried out over 2 years (from the inclusion of the first subject), with an expected period of 1 year for the enrolment and 1 further year for follow-up.
The main objective of this study is to show that the repeated (twice-daily) measurement of expired CO during hospitalization helps reduce smoking.
While e-cigs are commonly represented as safer alternatives to tobacco cigarettes, little is known regarding the health effects of their short- or long-term use. The responses and the e-cig components exerting these effects on the airways are largely unknown. This study will identify if specific e-cig flavors modify respiratory immune responses. This study will determine the effects of cinnamaldehyde (CA)-containing e-cigarettes on airway epithelial cell ciliary function (i.e., MCC) in humans. Additionally the study will determine the effects of CA-containing e-cigarettes on airway immune cells obtained through induced sputum (SI) after inhalation of CA-containing e-cig aerosols to determine CA-induced effects on a) immune cell function (e.g., phagocytosis, respiratory burst), b) immune cell surface phenotype, and c) mediator production in humans in vivo.
Pulmonary (lung) rehabilitation, which is done under the guidance of lung specialists/therapists. It includes breathing exercises, physical exercises, and exercises to increase tolerance of activity (stamina). This type of lung rehab has been shown to improve symptoms, quality of life, breathing, and walking distance. It has also been shown to decrease hospitalization and death rates in chronic obstructive pulmonary disease (COPD) and lung cancer patients. Comprehensive Care Management Program (CCMP), a program that includes educational sessions for tobacco cessation, phone calls, and a home action plan has also demonstrated benefit in addition to the pulmonary rehabilitation. In this study, the investigators have an opportunity to identify and intervene with COPD patients. The vast majority of early stage lung cancer patients are much more scared of their cancer than their COPD. Upon identification of COPD and recognition of patient tobacco habits for patients planned to undergo SBRT, interventions can potentially be made that will reduce COPD hospitalization rates, second primary lung cancer rates, and likely death rates. The interventions are broadly available and relatively easily instituted and include the following: seeing a doctor to diagnose their other underlying illness or illnesses (both respiratory and cardiovascular), smoking cessation if they are smokers, and CCMP's and pulmonary rehabilitation which have shown measurable COPD benefits in prior trials.
This project aims to develop electroretinogram as a new putative marker for dopamine release, and as a predictor of treatment response among patients seeking treatment for smoking cessation. Tobacco smoking continues to be a major public health challenge. Dopamine is a neurotransmitter released in the brain. Several lines of evidence suggest that dopamine release deficit in the brain is involved in the development and maintenance of nicotine dependence. The investigators hypothesize that smokers who do not have a deficit in dopamine release will more readily respond to behavioral treatment for smoking cessation, and in particular, financial incentives contingent on abstinence (Contingency Management). Previous pilot data suggest electroretinogram (ERG), which records electrical signals from the retina in response to light, is a clinically accessible correlate to dopamine release in the brain. The project proposes an ERG-based biomarker, and a pilot clinical trial to apply this biomarker to personalize smoking cessation treatment. This clinically tractable biomarker of central dopamine release may have a large number of future applications in the diagnosis and treatment of other mental illnesses and substance use disorders. The study will recruit normal controls and smokers, measure ERG before and after a standard dose of oral immediate release methylphenidate. Smokers will undergo a 12-week standardized treatment course of CM. The investigators will test whether smoking status and the response to CM are correlated to changes in ERG in response to methylphenidate challenge.
This is a prospective study comparing 4 groups: (1) non-smoking controls, (2) smokers without chronic obstructive pulmonary disease (COPD), (3) smokers with COPD, (4) severe asthma. Bronchial biopsy specimens from each subject will be obtained to produce air-liquid-interface cell cultures. These will then be used to make observations concerning cilia and mucus rheology. This is a first pilot study. The working hypothesis is that the largest group differences will be found for cilia densities; the latter metric was thus chosen as a primary criterion.
Hookah (water pipe) smoking is a new global epidemic. The World Health Organization wants to prohibit all claims that hookah is less harmful than cigarettes and wants hookah products to bear the same warning labels as cigarettes. But there is little scientific evidence to substantiate this proposal. Cigarettes, cigars, medicinal nicotine, and e-cigarettes all acutely impair brachial artery endothelial function (flow-mediated dilation, FMD). Also, cigarettes cause both acute and chronic impairment in coronary endothelial function, but the comparative effects of hookah are unknown. Hookah tobacco is heated with burning charcoal. So, the smoke contains "tar" and nicotine plus charcoal combustion products. These include carbon monoxide (CO) and proatherogenic oxidants (especially carbon-rich nanoparticles) that the study team expected to impair endothelial function.
This study will evaluate the impact of a proactive, EHR-supported enrollment strategy that links LDCT-eligible smokers with an evidence-based intervention comprised of a web-based program and integrated text messaging. The goal is to provide actionable findings about how to most effectively and cost efficiently promote abstinence in LDCT clinics.
