Biomarkers of Exposure and Effect in Standardized Research E-cigarette (SREC) Users

This study is focused on characterizing the toxic and carcinogenic potential of the Standardized Research E-cigarette (SREC) developed by the National Institute on Drug Abuse. In the environment of continuously changing e-cigarette market, SREC was developed as a model e-cigarette that will remain available for an extended period of time and can be used as a bridging element in various studies aimed at evaluating the value and limitations of e-cigarettes as tobacco risk reduction tools. Our overall goal is to generate initial reference data on chemical exposures and associated effects in smokers switching to SREC.

Randomized Trial of Electronic Cigarettes With or Without Nicotine in Smoking Cessation.

Background: Electronic cigarettes (EC) mainly containing nicotine (88-95 % of users) are widely and growingly used worldwide. It is estimated that there were 1.7 million daily users in France in 2016. Although the number of publications about its use is increasing exponentially, there are no evidence based, unbiased, head-to-head comparison data about its efficacy as an aid to smoking cessation. As of today, only two head-to-head randomized studies have been published, both reported negative results at the main endpoint but they used first and second generation EC delivering nicotine with low or unknown bioavailability. Recent EC deliver nicotine with largely improved bioavailability. One of the randomized studies compared EC with and without nicotine to nicotine patch and reported similar smoking cessation rate at main outcome. However, there is no published, double blind study comparing EC use with a well-studied, licensed smoking cessation medication. Superiority of EC with nicotine compared to EC without nicotine and to a reference smoking cessation medication while collecting also straightforward information about safety, would allow proposing EC with nicotine to the large population of smokers who intend to quit and situate it among the approved smoking cessation treatments. The clinical study's hypothesis: EC containing nicotine can be considered as a nicotine replacement therapy having, probably, a better bioavailability of nicotine than the marketed pharmaceutical NRTs, first line medications of smoking cessation. It is therefore of interest to compare EC containing nicotine to EC without nicotine but also to a reference medication with demonstrated efficacy in smoking cessation. We hypothesize that EC with nicotine provides a higher smoking abstinence rate than EC without nicotine and may be as good as varenicline, our reference medication.

Trauma-Informed Care for Smoking Cessation for Pregnancy

Trauma-informed approaches have been shown to support recovery from other substance use disorders and involve four key elements: (1) Realizing the prevalence of trauma and pathways to recovery, (2) Recognizing symptoms of trauma, (3) Responding by embedding knowledge of trauma into practices and policies and (4) Resisting re-traumatization (the 4Rs). In close partnership with Breathe California and a public safety-net clinic in San Francisco that serves primarily racial and ethnic minoritized (REM) pregnant women, the 4Rs along with the Ask, Advise, Assess, Assist and Arrange (the 5As) evidence-based intervention for tobacco cessation that is delivered by health care professionals and is a US Public Health Services clinical practice guideline for treating tobacco will be used to create and implement a smoking cessation intervention for pregnant women with experiences of trauma.

Leveraging Community Pharmacists to Optimize Smoking Cessation Services for Rural Smokers in Appalachia

The goal of this clinical trial is to evaluate the effectiveness and implementation of a pharmacist-delivered MTM (medication therapy management) approach, called QuitAid, to quitting cigarette smoking in rural Appalachia. The main questions it aims to answer are: * Is QuitAid, alone or combined with other quitting tobacco treatments, effective? * What makes QuitAid easy or hard to carry out? Is it cost effective? Is it easy to maintain? Treatment: All participants will be given at least 4 weeks of the nicotine patch. Some participants will be randomized (like the flip of a coin) to receive additional treatments (listed below). These groups will be compared to each other to see which combination works best to help them quit smoking. * Smokefree TXT - a texting program that helps people quit smoking * Tobacco quitline - 4 phone sessions to help people quit smoking * 8 weeks of NRT (nicotine replacement therapy in the form of nicotine patches or nicotine patches and lozenge) medication instead of 4 weeks * QuitAid - An MTM program given by the patient's pharmacist. This is a quitting smoking coaching program * Nicotine patch AND nicotine lozenge instead of just nicotine patches

Maternal Smoking Cessation and Pediatric Obesity Prevention

The objective of this study is to test the effect of smoking cessation in pregnancy or in lactation on preventing rapid infant adiposity gain. Investigators propose a randomized, controlled experiment among smoking pregnant women from 1st prenatal care visit through 6 months of postpartum period. Two-phase randomization will be applied to separate the effects of smoking cessation in two different critical periods (i.e., pregnancy and lactation) on infant adiposity gain. Investigators will first randomly assign 40 smoking pregnant women into either the multicomponent intervention (N=30) or the education-only control group (N=10). The multicomponent intervention group will receive education and counseling, monitoring and feedback, contingent financial incentives, and family support, while the control group will receive education only. At the end of pregnancy, investigators will further randomize successful quitters (estimated N=20) from the multi-component intervention group into either the continuous multi-component intervention group in lactation (N=10) or the education-only control group (N=10). All women and their newborns will be followed from enrollment to 6 months postpartum. The key outcomes include maternal smoking abstinence confirmed by urine-cotinine and infant gain in weight-for-length z-score. Specific Aim 1 is to examine the effects of maternal smoking cessation intervention in pregnancy on infant gain in weight-for-length z-score from birth to 6 months. Specific Aim 2 is to examine the effect of maternal smoking abstinence intervention in lactation and infant post-weaning gain in weight-for-length z-score among the women who have successfully quit smoking in pregnancy.

Dyadic Financial Incentive Treatments for Dual Smoker Couples

Smokers partnered with other smokers (i.e., dual-smoker couples) represent \~2/3 of all smokers. Dual-smoker couples (DSCs) are less likely to try to quit smoking and more likely to relapse during a quit attempt, reducing overall smoking cessation rates and representing a high-risk clinical population. Despite their high prevalence and risk for persistent smoking, however, there are limited data on smoking cessation interventions among DSCs. Building on previous research that suggests a) financial incentive treatments (FITs) are effective at increasing quit rates and b) dyadic adaptations of FITs are feasible for implementation in DSCs, the proposed study will systematically two versions of FITs to enhance smoking cessation among DSCs. In addition to determining the efficacy of these dyadic FITs for smoking abstinence in DSCs, the investigators will consider the cost and cost effectiveness of each adaptation as well as mechanisms of change to inform future implementation research. The investigators will additionally consider secondary outcomes including abstinence during treatment and long-term abstinence maintenance after end of treatment. The investigators will address these questions in a three-group randomized controlled trial (RCT). In all conditions, individuals who have smoking partners (i.e., targets) will receive usual care (combination fast and slow acting Nicotine Replacement Therapy + quitting resources). In two conditions, participants will receive incentives for abstinence at three time points (1, 3, and 6 months post-baseline). In the SFIT condition, only the target in a couple will be offered incentives; in the DFIT condition, both target and partner will be offered incentives. Primary efficacy outcome is % point-prevalence abstinence at 6 months post-baseline among targets. Secondary outcomes are point-prevalence abstinence at 1 and 3 months during the treatment and 6 months post-treatment (12-months post-baseline), as well as partner outcomes. The investigators will evaluate possible mechanisms of change including partner support and individual and partner motivation to quit as well as evaluate the cost and relative cost of each abstainer within and across condition. These data on the efficacy, mechanisms, and costs of FITs for DSCs will inform population level implementation and promote successful quitting in this treatment refractory population.

Impact of Smoking on Ultrasound-Guided Infraclavicular Brachial Plexus Block Onset and Duration

The present study will be conducted involving 40 patients aged 18-65 years with ASA physical status I and II, scheduled for acute or elective hand or forearm surgery under the lateral infraclavicular block. Patients will be divided into two groups based on smoking status: Group I (non-smokers) and Group II (smokers who smoke ≥20 cigarettes/day for over 1 year). Using a high-frequency linear ultrasound transducer, the axillary artery, vein, and the three nerve cords will be identified in the lateral infraclavicular region. After disinfection with ethanol-chlorhexidine, a sterile drape will be placed, and the attending anesthesiologist will perform the ultrasound-guided infraclavicular brachial plexus block with a triple injection technique. A total of 10 mL of bupivacaine 0.25% and prilocaine 0.05% will be injected at all three nerve cords. The primary outcome will be the sensory blockade onset time, while secondary outcomes will include the duration of sensory and motor blockade, motor blockade onset time, time to first postoperative rescue analgesia, and total consumption of rescue analgesia. Postoperative pain will be assessed using the Visual Analogue Scale (VAS) within the first 24 hours at intervals of 2, 4, 8, 12, 16, and 24 hours. If VAS exceeds 30 cm, rescue analgesia with 0.05 mg/kg intravenous morphine sulfate will be administered.
