Using Smartwatches to Monitor Smoking in Real-life Situations
Background: It is important to quickly identify when people are at risk of smoking. Most current methods rely on people reporting when they smoke or what makes them want to smoke. But this can be hard for people to do and may not always be accurate. Other methods use special gadgets to identify smoking movements, but these may not always work well in real life. We want to see if we can use devices available on the market such as smartwatches to identify signs in the body and hand movements that might indicate when someone is about to smoke, is currently smoking, or has just smoked. Objective: To record body signs and hand movements before, during, and after smoking in real-life and in a lab to see how they change when someone is craving cigarettes, while a person is smoking, and after a person has smoked. Eligibility: People who are 21 years or older and smoke, have no college degree or be currently enrolled in college, and are low-income earners. To participate in the study, participants have to pass a breath test that shows they smoke cigarettes and, for women, a urine test to show that they are not currently pregnant. Design: Participants will complete an eligibility survey to see if they qualify to be in the study. If they qualify, they will answer a brief baseline survey that includes questions about themselves, their health, and their smoking behavior. Participants will get a smartwatch to wear for 3 days at home, log each time they are about to smoke and have finished smoking, and answer a 5-question health survey via the app. They will get instructions on how to set up and wear the smartwatch. They will download a mobile application on their phone. The app will collect data from the smartwatch. Participants will then come to the lab but will be asked not to smoke or drink alcohol for at least 12 hours. They will have to take a breath test to show they have not smoked or had alcohol. They will also give a blood sample. In the lab, they will sit in a room where they will be hooked to devices that monitor their vitals such as heart rate and blood pressure for one hour. They will also wear a smartwatch on each hand. While they are in the smoking room, they will go through 3 different phases: (a) pre-smoking where they will be asked to stay seated for about 25 minutes, (b) smoking where they will be asked to smoke as many cigarettes of their choice as they want for about 10 to 15 minutes, (c) post-smoking where they will be asked to stay seated, not smoking, for about 25 minutes. They will answer a brief 10-minute health survey before and after the session. Participation will last for 3 days of home monitoring and 2 visits to the research clinic that last about 2 hours.

Racial Differences in Circadian and Sleep Mechanisms for Nicotine Dependence, Craving, and Withdrawal
The number one preventable cause of death in the world is tobacco use. Cigarette smoking in particular, costs an estimated $300 billion due to expenses related to medical care and lost productivity. Despite similar smoking prevalence rates, blacks suffer disproportionately from smoking-related harms compared to whites.Sleep disparities such as shortened sleep duration, shorter circadian periodicity, earlier chronotype, and increased variability of sleep timing have been reported more frequently in blacks compared to whites. Given that poor sleep quality predicts relapse from smoking cessation programs, particularly among socioeconomically disadvantaged adults, sleep deficiencies and irregular timing of sleep may impact smoking craving and withdrawal symptoms over the course of the 24-hour day. Surprisingly, few studies have examined these temporal patterns of smoking and craving, and none with regard to sleep disruption, chronotype or racial disparities. A better understanding of these factors may explain heterogeneity within the smoking population, especially in minorities. Thus, the purpose of this proposal is to test the central hypothesis that the impact of chronotype and impaired sleep on cigarette usage as well as smoking dependence, urge/craving, and withdrawal depends on race.

Negative Pressure Wound Therapy Devices in Total Knee Arthroplasty
This study is a single-center, prospective, randomized, open-label clinical trial evaluating three commercially available closed-incision negative pressure wound therapy (ciNPWT) devices: NPseal, PICO, and Prevena, in adult patients undergoing primary total knee arthroplasty (TKA) who meet predefined high-risk criteria for wound complications. A total of approximately 300 participants will be enrolled and randomized in a 1:1:1 fashion to receive one of the three study dressings applied over the closed surgical incision at the end of the procedure. All participants will otherwise receive standard perioperative and postoperative care. The primary follow-up period will extend through 90 days after surgery. The primary objective is to compare the incidence of 90-day surgical site complications, including superficial infection, wound dehiscence, seroma, and hematoma, across the three dressing groups. Secondary objectives include evaluation of device usability, patient experience, and device-related issues (such as loss of seal, alarms, tubing or pump problems, fluid saturation, and premature dressing changes), as well as assessment of the interaction between skin closure method and device performance. Research-specific activities are limited to eligibility confirmation, informed consent, randomization, administration of a brief postoperative patient survey at approximately postoperative day 7 and/or dressing removal, provider assessment of the dressing at removal, and collection of clinical outcomes from the medical record. No additional blood draws, imaging, or invasive procedures are required for participation. This study is designed to address a gap in the literature by providing head-to-head comparative data on commonly used ciNPWT systems in a high-risk primary TKA population, with the goal of informing postoperative wound management strategies in clinical practice.

Project DEDUCE: Digital Envirotyping to Develop Understanding of Cigarette Smoking and the Environment
Tobacco use is a chronic relapsing condition. That is, even with state-of-the-art treatment, \>70% of smoking cessation attempts end in a return to regular smoking. Research demonstrates that everyday environments associated with smoking trigger craving for cigarettes, provoke smoking, and lead to relapse. However, despite this knowledge, understanding of environmental correlates of smoking has been limited by a reliance on self-report, leading to imprecise information about the physical environments in which people live. To overcome this challenge, the research team has pioneered the development of digital envirotyping, which uses digital tools (e.g., sensors, cameras, artificial intelligence) to efficiently and accurately characterize and categorize environments with the goal of identifying environmental markers of behavior and health. Foundational to the digital envirotyping research is computer vision (CV), a type of artificial intelligence (AI) that enables computer systems to recognize objects and scenes in digital images, mimicking how humans perceive and understand visual information. With CV researchers can extract detailed and accurate information (i.e., objects and location types) about the everyday environments of people who smoke (PWS) and relate that information to smoking behavior. After validating the use of CV, the researchers used CV to develop enviromarkers of relapse risk. Importantly, they identified a novel enviromarker in which people at greater risk for relapse when they quit are exposed to a more consistent level of environment-related smoking risk as they move between their smoking and nonsmoking environments. Research is now needed to advance digital envirotyping and enviromarker development in the field of tobacco addiction. The study will recruit a diverse, national sample of n=500 adults who are interested in quitting smoking. For two weeks prior to quitting, they will undergo photoEMA in which they will take two pictures of their current environment when they smoke, and randomly 10 times per day resulting in \>300,000 images total. Cessation will be supported by nicotine replacement therapy (i.e., nicotine patch). The primary clinical outcome will be days to relapse. Specific aims are to (1) further develop, refine, and validate methods for efficient digital envirotyping at scale, (2) leverage CV and AI approaches to develop enviromarkers of smoking relapse, and (3) conduct analyses to increase understanding of environmental smoking risk in women and individuals with low socioeconomic status.

Literacy and Smoking Risk Communications
Objectives: Smokers with varying levels of health literacy as assessed by the S-TOFHLA (i.e., inadequate, marginal, adequate) recruited from the community will listen to one of 4 different types of messages emphasizing the health consequences of smoking recorded on a computer in the form of audio scripts (i.e., a human voice pre-recorded on a computer will read each message). Messages written at a 5th to 6th grade reading level will be concurrently presented in written form via a computer monitor and be manipulated in terms of 1) emotionality (i.e., primarily fact- vs. primarily emotion-based), and 2) framing (i.e., gain-framed messages that highlight the potential benefits of quitting smoking vs. loss-framed messages that emphasize the potential costs of failing to quit smoking). Emotionality and framing will be completely crossed to create four different types of messages, 1) factual gain-framed (FGF), 2) factual loss-framed (FLF), 3) emotional gain-framed (EGF), and 4) emotional loss-framed (ELF). The primary objectives are to: 1. Examine whether main effects emerge for health literacy as assessed by the S-TOFHLA (inadequate, marginal, adequate) and the different message types (fact- vs. emotion-based and gain- vs. loss-framed) on the primary explicit and implicit outcomes: a) intention to quit, and b) implicit and explicit attitudes toward smoking. 2. Examine whether health literacy interacts with the different types of messages (fact-based vs. emotion-based and gain-framed vs. loss-framed) to influence the primary explicit and implicit outcome measures: a) intention to quit smoking, and b) implicit and explicit attitudes toward smoking. A secondary, exploratory aim is to: 3. Examine potential associations between a) the primary explicit and implicit outcomes, and b) the secondary explicit and implicit outcomes: knowledge, risk perception, attitudes, self-efficacy, message evaluations, implicit fear of disease, and implicit associations between smoking and disease.

Impact of Ban on Smoking in Pubs, Restaurants and Nightclubs on Endothelial Function in Workers
Endothelium is considered a real member, so it is contributing to determine the vascular homeostasis. The presence of endothelial dysfunction, evaluated in peripheral arteries by non-invasive study of the variation of gauge of the brachial artery as a result of post-ischemic hyperemia (FMD), is predictive of occurrence of major cardiovascular events. Several recent studies have shown that passive smoking is correlated with endothelial dysfunction and, therefore, non-smokers exposed subjects to passive smoking, have an increased risk of occurrence cardiovascular pathologies. From January 2008, a ministerial decree will ban smoking in bars, restaurants and nightclubs. The impact of exposure end to smoking in non-smoking subjects, as part of a prospective study and controlled, has never been evaluated.

CPT-SMART for Treatment of PTSD and Cigarette Smoking
Smoking is the leading cause of preventable illness, disability, and death in the United States. The rate of smoking is disproportionately higher among Veterans with posttraumatic stress disorder (PTSD). Unfortunately, smoking cessation efforts that are effective in the general population have shown limited effectiveness in smokers with PTSD. The high smoking rate and difficulty with achieving abstinence indicate a critical need to develop effective interventions for Veterans who smoke and have PTSD. The investigators' data indicate that negative emotions and trauma reminders are associated with relapse for smokers with PTSD. In this context, an ideal strategy may be to combine evidence-based PTSD treatment with intensive smoking cessation treatment to maximize quit rates. Cognitive processing therapy (CPT) is a well-established evidence-based treatment for PTSD. The investigators have successfully developed a treatment manual that combines CPT with cognitive-behavioral counseling for smoking cessation. Contingency management (CM) is another intensive behavioral treatment that has been shown to help with reducing smoking. CM provides positive reinforcers such as money to individuals misusing substances contingent upon abstinence from use. The primary goal of this study is to evaluate the efficacy of a treatment that combines CM with cognitive-behavioral smoking cessation counseling, smoking cessation medication, and CPT. Proposed is a randomized, two-arm clinical trial in which 120 Veteran smokers with PTSD will be randomized to either: 1) COGNITIVE PROCESSING THERAPY with SMOKING ABSTINENCE REINFORCEMENT THERAPY (CPT-SMART) or 2) COMBINED CONTACT CONTROL, an intervention identical to CPT-SMART in PTSD and smoking treatment, except for using payment that is not contingent on abstinence. Specific aims include: AIM 1) To evaluate the efficacy of CPT-SMART on rates of short- and long-term abstinence from cigarettes; AIM 2) To evaluate the impact of CPT-SMART on treatment engagement and utilization; and an EXPLORATORY AIM) To explore mechanisms of CPT-SMART on long-term smoking abstinence. The positive public health impact of reducing smoking among Veterans with PTSD could be enormous as it would prevent significant smoking-related morbidity and mortality.

Smoking Cessation for Depressed Smokers
Objectives: Primary Aim: To conduct a preliminary randomized trial in smokers with current recurrent major depressive disorder (MDD), current MDD with a single episode of 2 years or more, and current dysthymia comparing combined cognitive behavioral analysis system of psychotherapy (CBASP) and standard smoking cessation treatment (ST) (CBASP/ST) to combined Health Education and ST treatment (HE/ST) to: 1\. Examine the effects of CBASP/ST on both short and long-term point prevalence abstinence Secondary Aims: 1. To test the hypothesis that depressed smokers in the CBASP/ST treatment will experience greater decreases in depressive symptoms from baseline to each of our follow-up assessment points, compared to depressed smokers in the HE/ST treatment, and; 2. That depressed smokers in the CBASP/ST treatment will experience greater improvements in psychosocial functioning from baseline to follow-up assessment points, compared to depressed smokers in the ST treatment. 3. To evaluate between subject neurophysiological predictors of abstinence at 3 and 6 months, and: 4. To evaluate within-subject changes in neurophysiological responses to emotional and smoking-related stimuli across treatment sessions, and the relation of these changes to abstinence and depressive symptoms at end of treatment, and 3- and 6-months.
