Filter by: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.
This study is being done to develop new methods to help smokers with schizophrenia to successfully reduce their smoking and/or quit. This is not a treatment study, but will help find new techniques to create better treatments. Specifically, the investigators are interested in learning more about how thoughts and attention problems associated with schizophrenia might play a role in smoking, as well as the impact of cognitive (thinking, reasoning, and remembering) training and brain stimulation on these symptoms and on actual smoking.
Cigarette smoking constitutes the greatest preventable cause of mortality and morbidity in the US. The most critical period for long term success of smoking cessation appears to be in the first 7 days after the quit date. A metaanalysis of 3 pharmacotherapy trials revealed that abstinence during the first 7 days was the strongest predictor of 6 month outcomes (n=1649; Odds ratio: 1.4, P <0.0001; Ashare et al. 2013). Prodigious relapse rates during this first week of smoking cessation are likely due to behavioral and neurobiological factors that contribute to high cue-associated craving and low executive control over smoking. The long term goal of the research is to develop evidence-based transcranial magnetic stimulation protocols to facilitate abstinence during this critical period.
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.
