- Abstract
Although oral health care providers (OHP) are key in the secondary prevention of eating disorders (ED), the majority are not engaged in assessment, referral, and case management. This innovative pilot project developed and evaluated a web-based training program for dental and dental hygiene students and providers on the secondary prevention of ED. The intervention combined didactic and skill-based objectives to train OHP on ED and its oral health effects, OHP roles, skills in identifying the oral signs of ED, communication, treatment, and referral. Using a convenience sample of OHP (n=66), a pre-/post-test evaluated short-term outcomes and user satisfaction. Results revealed statistically significant improvements in self-efficacy (p<.001); knowledge of oral manifestations from restrictive behaviors (p<.001) and purging behaviors (p<.001); knowledge of oral treatment options (p<.001); and attitudes towards the secondary prevention of ED (p<.001). Most participants strongly agreed or agreed that the program provided more information (89 percent) and resources (89 percent) about the secondary prevention of ED than were currently available; 91 percent strongly agreed or agreed that they would access this program for information regarding the secondary prevention of ED. This pilot project provides unique training in the clinical evaluation, patient approach, referral, and oral treatment that takes a multidisciplinary approach to address ED. [ABSTRACT FROM AUTHOR]

While the use of smokeless tobacco products has increased, there has been a paucity of research evaluating interventions to help users quit. This study is the first large-scale randomized trial evaluating two levels of self-help cessation intervention with adult smokeless tobacco (SLT) users. Smokeless users in five Northwest states were recruited to call a toll-free number and 1069 users were randomized to receive one of two interventions, Manual Only (MAN) or Assisted Self-Help (ASH), who received a video and two support phone calls in addition to the manual. The study demonstrated that low-cost minimal interventions done by mail and phone can help a sizable proportion of SLT users quit both SLT and all tobacco use. Follow-up data at 6 months showed that subjects in the ASH condition had a significantly higher quit rate for both smokeless (23.4% vs. 18.4%, p < 0.05) and all tobacco use (21.1% vs. 16.5%, p < 0.05), using an intent-to-treat model. Further analysis revealed that use of the recommended cessation procedures mediated the effect of intervention condition on outcomes. This may be the result of phone counselors getting subjects to carry out behavioral cessation procedures. Public health implications for this intervention are discussed. [ABSTRACT FROM AUTHOR]

SMOKELESS tobacco ,WEIGHT loss - Abstract
This study explored the factors associated with female smokeless tobacco (ST) use and examined gender differences in factors related to use. Interviews were conducted either in person or by telephone with 51 female and 59 male users from the Pacific Northwest. The interview included both quantitative and qualitative items assessing personal, social, and substance use variables. Male and female users were found to be similar in a variety of areas, such as reasons for initiating use, use of ST in response to different mood states, and high rates of experimentation with other drugs. However, female users reported using ST for weight control more extensively, identified a greater influence by other female users, and reported fewer friends knowing about their use. Male users reported using ST more often during sports activities and in the workplace than did female users, and were almost three times more likely to be highly addicted to ST. The implications of the study for the development of prevention and cessation programs are discussed. [ABSTRACT FROM AUTHOR]

Public aspects of medicine ,RA1-1270 - Abstract
Abstract Background Web-based health behavior change programs can reach large groups of disparate participants and thus they provide promise of becoming important public health tools. Data on participant rurality can complement other demographic measures to deepen our understanding of the success of these programs. Specifically, analysis of participant rurality can inform recruitment and social marketing efforts, and facilitate the targeting and tailoring of program content. Rurality analysis can also help evaluate the effectiveness of interventions across population groupings. Methods We describe how the RUCAs (Rural-Urban Commuting Area Codes) methodology can be used to examine results from two Randomized Controlled Trials of Web-based tobacco cessation programs: the ChewFree.com project for smokeless tobacco cessation and the Smokers' Health Improvement Program (SHIP) project for smoking cessation. Results Using RUCAs methodology helped to highlight the extent to which both Web-based interventions reached a substantial percentage of rural participants. The ChewFree program was found to have more rural participation which is consistent with the greater prevalence of smokeless tobacco use in rural settings as well as ChewFree's multifaceted recruitment program that specifically targeted rural settings. Conclusion Researchers of Web-based health behavior change programs targeted to the US should routinely include RUCAs as a part of analyzing participant demographics. Researchers in other countries should examine rurality indices germane to their country.

- Abstract
Background: Evidence-based models are needed to deliver exercise-related services for knee osteoarthritis efficiently and according to patient needs ., Objective: To examine a stepped exercise program for patients with knee osteoarthritis (STEP-KOA)., Design: Randomized controlled trial. (ClinicalTrials.gov: NCT02653768)., Setting: 2 U.S. Department of Veterans Affairs sites., Participants: 345 patients (mean age, 60 years; 15% female; 67% people of color) with symptomatic knee osteoarthritis., Intervention: Participants were randomly assigned in a 2:1 ratio to STEP-KOA or an arthritis education (AE) control group, respectively. The STEP-KOA intervention began with 3 months of an internet-based exercise program (step 1). Participants who did not meet response criteria for improvement in pain and function after step 1 progressed to step 2, which involved 3 months of biweekly physical activity coaching calls. Participants who did not meet response criteria after step 2 went on to in-person physical therapy visits (step 3). The AE group received educational materials via mail every 2 weeks., Measurements: Primary outcome was Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score. Scores for the STEP-KOA and AE groups at 9 months were compared by using linear mixed models., Results: In the STEP-KOA group, 65% of participants (150 of 230) progressed to step 2 and 35% (81 of 230) to step 3. The estimated baseline WOMAC score for the full sample was 47.5 (95% CI, 45.7 to 49.2). At 9-month follow-up, the estimated mean WOMAC score was 6.8 points (CI, -10.5 to -3.2 points) lower in the STEP-KOA than the AE group, indicating greater improvement., Limitation: Participants were mostly male veterans, and follow-up was limited., Conclusion: Veterans in STEP-KOA reported modest improvements in knee osteoarthritis symptoms compared with the control group. The STEP-KOA strategy may be efficient for delivering exercise therapies for knee osteoarthritis., Primary Funding Source: Department of Veterans Affairs, Health Services Research and Development Service.

- Abstract
Introduction: Smokeless tobacco (ST) use significantly affects morbidity and mortality and remains disproportionally prevalent in rural and medically underserved communities. Few programs exist for rural smokeless tobacco users. Text-based interventions may increase the reach of cessation interventions; yet, none has tested them in ST users. We evaluated the feasibility, acceptability, and preliminary efficacy of a text-based Scheduled Gradual Reduction (SGR) intervention in rural and underserved ST users., Methods: ST users were randomized in 2:1 fashion to the SGR group (N = 65), a text-based reduction program plus text-based support counseling messages or text-based support messages only group (N = 33). We surveyed participants at 30-days post intervention initiation to assess feasibility and acceptability and examined self-report 7-day point prevalence cessation at 30-days and 6-months post intervention initiation in the two arms., Results: We achieved benchmarks for feasibility and acceptability. Among the SGR participants 51% (n = 48) reported that intervention was useful in helping them quit, 83% (n = 48) indicated that they would recommend the intervention to a friend. Over 95% (n = 39) of SGR participants said that they read all alert texts. The SGR participants had a higher quit rate at 30-days compared to support messages alone (SGR = 21.5%, Control = 9.1%, p = 0.1627, Cohen's d equivalent = 0.56, medium effect). However, the quit rate at 6-months was 21% (p = 0.9703) for both groups., Conclusions: A text-based intervention was feasible and acceptable among underserved ST users. SGR helped promote short-term cessation. The text-based interventions both had long-term efficacy. Given that text-based interventions have the potential to increase reach in underserved ST users, further testing is warranted., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

- Abstract
Introduction: Cannabis and tobacco couse is common and could expose users to higher levels of toxicants. No studies have examined biomarkers of toxicant exposure in cousers of cannabis and cigarettes, compared with cigarette smokers (CS)., Aims and Methods: Adult daily CS were recruited from 10 US sites for a study of reduced nicotine cigarettes. In this analysis of baseline data, participants were categorized as either cousers of cannabis and tobacco (cousers; N = 167; urine positive for 11-nor-9-carboxy-Δ 9-tetrahydrocannnabinol and self-reported cannabis use ≥1×/week), or CS (N = 911; negative urine and no self-reported cannabis use). Participants who did not meet either definition (N = 172) were excluded. Self-reported tobacco and cannabis use and tobacco and/or combustion-related biomarkers of exposure were compared between groups., Results: Compared to CS, cousers were younger (couser Mage = 38.96, SD = 13.01; CS Mage = 47.22, SD = 12.72; p < .001) and more likely to be male (cousers = 67.7%, CS = 51.9%, p < .001). There were no group differences in self-reported cigarettes/day, total nicotine equivalents, or breath carbon monoxide, but cousers had greater use of non-cigarette tobacco products. Compared to CS, cousers had higher concentrations of 3-hydroxypropylmercapturic acid, 2-cyanoethylmercapturic acid, S-phenylmercapturic acid, 3-hydroxy-1-methylpropylmercapturic acid (ps < .05), and phenanthrene tetraol (p < .001). No biomarkers were affected by number of cannabis use days/week or days since last cannabis use during baseline (ps > .05)., Conclusions: Cousers had higher concentrations of biomarkers of exposure than CS, but similar number of cigarettes per day and nicotine exposure. Additional studies are needed to determine whether cannabis and/or alternative tobacco products are driving the increased toxicant exposure., Implications: Cousers of cannabis and tobacco appear to be exposed to greater levels of harmful chemicals (ie, volatile organic compounds and polycyclic aromatic hydrocarbons), but similar levels of nicotine as CS. It is unclear if the higher levels of toxicant exposure in cousers are due to cannabis use or the increased use of alternative tobacco products compared with CS. It is important for studies examining biomarkers of exposure among CS to account for cannabis use as it may have a significant impact on outcomes. Additionally, further research is needed examining exposure to harmful chemicals among cannabis users., (© The Author(s) 2019.

- Abstract
Background: Physical therapy (PT) and other exercise-based interventions are core components of care for knee osteoarthritis (OA), but both are underutilized, and some patients have limited access to PT services. This clinical trial is examining a STepped Exercise Program for patients with Knee OsteoArthritis (STEP-KOA). This model of care can help to tailor exercise-based interventions to patient needs and also conserve higher resource services (such as PT) for patients who do not make clinically relevant improvements after receiving less costly interventions., Methods / Design: Step-KOA is a randomized trial of 345 patients with symptomatic knee OA from two Department of Veterans Affairs sites. Participants are randomized to STEP-KOA and Arthritis Education (AE) Control groups with a 2:1 ratio, respectively. STEP-KOA begins with 3 months of access to an internet-based exercise program (Step 1). Participants not meeting response criteria for clinically meaningful improvement in pain and function after Step 1 progress to Step 2, which involves bi-weekly physical activity coaching calls for 3 months. Participants not meeting response criteria after Step 2 progress to in-person PT visits (Step 3). Outcomes will be assessed at baseline, 3, 6 and 9 months (primary outcome time point). The primary outcome is the Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC), and secondary outcomes are objective measures of physical function. Linear mixed models will compare outcomes between the STEP-KOA and AE control groups at follow-up. We will also evaluate patient characteristics associated with treatment response and conduct a cost-effectiveness analysis of STEP-KOA., Discussion: STEP-KOA is a novel, efficient and patient-centered approach to delivering exercise-based interventions to patients with knee OA, one of the most prevalent and disabling health conditions. This trial will provide information on the effectiveness of STEP-KOA as a novel potential model of care for treatment of OA., Trial Registration: Clinicaltrials.gov, NCT02653768 (STepped Exercise Program for Knee OsteoArthritis (STEP-KOA)), Registered January 12, 2016.

- Abstract
Importance: The optimal temporal approach for reducing nicotine to minimally or nonaddictive levels in all cigarettes sold in the United States has not been determined., Objectives: To determine the effects of immediate vs gradual reduction in nicotine content to very low levels and as compared with usual nicotine level cigarettes on biomarkers of toxicant exposure., Design, Setting, and Participants: A double-blind, randomized, parallel-design study with 2 weeks of baseline smoking and 20 weeks of intervention was conducted at 10 US sites. A volunteer sample of daily smokers with no intention to quit within 30 days was recruited between July 2014 and September 2016, with the last follow-up completed in March 2017., Interventions: (1) Immediate reduction to 0.4 mg of nicotine per gram of tobacco cigarettes; (2) gradual reduction from 15.5 mg to 0.4 mg of nicotine per gram of tobacco cigarettes with 5 monthly dose changes; or (3) maintenance on 15.5 mg of nicotine per gram of tobacco cigarettes., Main Outcomes and Measures: Between-group differences in 3 co-primary biomarkers of smoke toxicant exposure: breath carbon monoxide (CO), urine 3-hydroxypropylmercapturic acid (3-HPMA, metabolite of acrolein), and urine phenanthrene tetraol (PheT, indicator of polycyclic aromatic hydrocarbons) calculated as area under the concentration-time curve over the 20 weeks of intervention., Results: Among 1250 randomized participants (mean age, 45 years; 549 women [44%]; 958 [77%] completed the trial), significantly lower levels of exposure were observed in the immediate vs gradual reduction group for CO (mean difference, -4.06 parts per million [ppm] [95% CI, -4.89 to -3.23]; P < .0055), 3-HPMA (ratio of geometric means, 0.83 [95% CI, 0.77 to 0.88]; P < .0055), and PheT (ratio of geometric means, 0.88 [95% CI, 0.83 to 0.93]; P < .0055). Significantly lower levels of exposure were observed in the immediate reduction vs control group for CO (mean difference, -3.38 [95% CI, -4.40 to -2.36]; P < .0055), 3-HPMA (ratio of geometric means, 0.81 [95% CI, 0.75 to 0.88]; P < .0055), and PheT (ratio of geometric means, 0.86 [95% CI, 0.81 to 0.92]; P < .0055). No significant differences were observed between the gradual reduction vs control groups for CO (mean difference, 0.68 [95% CI, -0.31 to 1.67]; P = .18), 3-HPMA (ratio of geometric means, 0.98 [95% CI, 0.91 to 1.06]; P = .64), and PheT (ratio of geometric means, 0.98 [95% CI, 0.92 to 1.04]; P = .52)., Conclusions and Relevance: Among smokers, immediate reduction of nicotine in cigarettes led to significantly greater decreases in biomarkers of smoke exposure across time compared with gradual reduction or a control group, with no significant differences between gradual reduction and control., Trial Registration: clinicaltrials.gov Identifier: NCT02139930.

- Abstract
Objective: To compare the effectiveness of physical therapy (PT, evidence-based approach) and internet-based exercise training (IBET), each vs a wait list (WL) control, among individuals with knee osteoarthritis (OA)., Design: Randomized controlled trial of 350 participants with symptomatic knee OA, allocated to standard PT, IBET and WL control in a 2:2:1 ratio, respectively. The PT group received up to eight individual visits within 4 months. The IBET program provided tailored exercises, video demonstrations, and guidance on progression. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC, range 0 [no problems]-96 [extreme problems]), assessed at baseline, 4 months (primary time point) and 12 months. General linear mixed effects modeling compared changes in WOMAC among study groups, with superiority hypotheses testing differences between each intervention group and WL and non-inferiority hypotheses comparing IBET with PT., Results: At 4-months, improvements in WOMAC score did not differ significantly for either the IBET or PT group compared with WL (IBET: -2.70, 95% Confidence Interval (CI) = -6.24, 0.85, P = 0.14; PT: -3.36, 95% (CI) = -6.84, 0.12, P = 0.06). Similarly, at 12-months mean differences compared to WL were not statistically significant for either group (IBET: -2.63, 95% CI = -6.37, 1.11, P = 0.17; PT: -1.59, 95% CI = -5.26, 2.08, P = 0.39). IBET was non-inferior to PT at both time points., Conclusions: Improvements in WOMAC score following IBET and PT did not differ significantly from the WL group. Additional research is needed to examine strategies for maximizing benefits of exercise-based interventions for patients with knee OA., Trial Registration: NCT02312713., (Published by Elsevier Ltd.)

- Abstract
Preventing oral-systemic health issues relies on evidence-based interventions across various system-level target groups. Although the use of theory- and evidence-based approaches has been encouraged in developing oral health behavior change programs, the translation of theoretical constructs and principles to behavior change interventions has not been well described. Based on a series of six systematic steps, Intervention Mapping provides a framework for effective decision making with regard to developing, implementing, and evaluating theory- and evidence-informed, system-based behavior change programs. This article describes the application of the Intervention Mapping framework to develop the EAT (evaluating, assessing, and treating) evidence-based intervention with the goal of increasing the capacity of oral health providers to engage in secondary prevention of oral-systemic issues associated with disordered eating behaviors. Examples of data and deliverables for each step are described. In addition, results from evaluation of the intervention via randomized control trial are described, with statistically significant differences observed in behavioral outcomes in the intervention group with effect sizes ranging from r=0.62 to 0.83. These results suggest that intervention mapping, via the six systematic steps, can be useful as a framework for continued development of preventive interventions.

- Abstract
Background: An essential component of evaluating potential modified risk tobacco products is to determine how consumers use the product and resulting effects on biomarkers of toxicant exposure., Study Design: Cigarette smokers (n=391) recruited in Minnesota and Oregon were randomised to either snus or 4 mg nicotine gum for 12 weeks. Participants were instructed to completely switch from cigarettes to these products. Urine samples were collected to analyse for carcinogenic tobacco-specific nitrosamine metabolites (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol and N'-nitrosonornicotine and their glucuronides) and nicotine metabolites (total cotinine and nicotine equivalents) levels., Results: Of the 391 participants randomised, 52.9% were male, the mean±SD age was 43.9±12.5 years, baseline number of cigarettes/day was 18.0±6.5 and Fagerstrom Test for Nicotine Dependence score was 5.1±2.0. The mean±SD number of snus pouches used/week at week 6 prior to tapering was 39.1±24.0 and nicotine gum pieces used was 37.6±26.3. Dual use of cigarettes and these products were observed in 52.9% and 58.2% of those assigned to snus and nicotine gum, respectively, at week 12. The end of treatment biochemically verified (carbon monoxide, CO<6 ppm) 7-day avoidance of cigarettes was 21.9% in the snus group and 24.6% in the nicotine gum group. Toxicant exposure in the nicotine gum group was significantly less when compared to snus., Conclusions: Snus performed similarly to nicotine gum in cigarette smokers who were interested in completely switching to these products, but was associated with less satisfaction and greater toxicant exposure than nicotine gum., Trial Registration Number: NCT: 00710034., (Published by the BMJ Publishing Group Limited.

- Abstract
Smokeless tobacco products sold in the United States vary significantly in yields of nicotine and tobacco-specific nitrosamines (TSNA). With the passage of the Family Smoking Prevention and Tobacco Control Act, the Food and Drug Administration now has the authority to establish product standards. However, limited data exist determining the relative roles of pattern of smokeless tobacco use versus constituent levels in the smokeless tobacco product in exposure of users to carcinogens. In this study, smokeless tobacco users of brands varying in nicotine and TSNA content were recruited from three different regions in the U.S. Participants underwent two assessment sessions. During these sessions, demographic and smokeless tobacco use history information along with urine samples to assess biomarkers of exposure and effect were collected. During the time between data collection, smokeless tobacco users recorded the amount and duration of smokeless tobacco use on a daily basis using their diary cards. Results showed that independent of pattern of smokeless tobacco use and nicotine yields, levels of TSNA in smokeless tobacco products played a significant role in carcinogen exposure levels. Product standards for reducing levels of TSNA in smokeless tobacco products are necessary to decrease exposure to these toxicants and potentially to reduce risk for cancer., (©2014 American Association for Cancer Research.)

- Abstract
Objectives: To compare 4 online and off-line recruiting methods., Methods: Young adult smokers (n=3353) were recruited to a trial comparing smoking cessation services with an online health risk assessment (HRA), online ads, offline materials, and quit-line screening., Results: Online ads (n=1426; $41.35) and off-line materials recruited the most smokers (n=1341; $56.23) for the lowest cost. Quitline screening was more expensive (n=189; $132.22), but enrollees used cessation services the most (34%-82%). Online HRA was least successful and most costly (n=397; $630.85) but had the highest follow-up (45%-55%)., Conclusions: Online ads and off-line materials were most effective and cost-effective methods.

- Abstract
Background: Recently, oral tobacco products have been marketed specifically towards cigarette smokers. These products come in different nicotine doses and formulations (snus vs. lozenge). To date, little research has been conducted to determine how smokers respond to these products. The goal of this study was to examine if smokers prefer certain oral tobacco products based on their specific characteristics., Methods: Smokers interested in quitting underwent a sampling phase and a treatment phase. The sampling phase consisted of testing five different products varying in nicotine dose (high vs. moderate vs. low) and formulation (snus vs. lozenge): General Snus, Camel Snus, Marlboro Snus, Stonewall and Ariva. Each product was sampled in the natural environment on separate days. At the end of the sampling period, subjects chose which product they would use during the 2-week cigarette abstinence phase., Results: General Snus (high nicotine) was not preferred by any smoker. No significant differences in preferences were observed across the other tobacco products. During the smoking cessation phase, Camel Snus was generally associated with greater craving relief and satisfaction, reduced use of cigarettes, and greater abstinence during follow-up compared to other products., Conclusion: There were no differences in preferences for four of the five oral tobacco products but higher nicotine oral tobacco products were associated with better cessation outcomes among smokers who chose these products., (Copyright © 2011 Elsevier Ireland Ltd.

- Abstract
Purpose: To assess the effect of bifocal soft contact lenses on the accommodative errors (lags) of young adults. Recent studies suggest that bifocal soft contact lenses are an effective myopia control treatment although the underlying mechanism is not understood., Methods: Accommodation responses were measured for four target distances: 100, 50, 33 and 25 cm in 35 young adult subjects (10 emmetropes and 25 myopes; mean age, 22.8 +/- 2.5 years). Measurements were made under both monocular and binocular conditions with three types of lenses: single vision distance soft contact lenses (SVD), single vision near soft contact lenses (SVN; +1.50 D added to the distance prescription) and bifocal soft contact lenses (BF; +1.50 D add)., Results: For the SVD lenses, all subjects exhibited lags of accommodation, with myopes accommodating significantly less than emmetropes for the 100 and 50 cm target distances (p < 0.05). With the SVN lenses, there was no significant difference in accommodative responses between emmetropes and myopes. With the BF lenses, both emmetropic and myopic groups exhibited leads in accommodation for all target distances, with emmetropes showing significantly greater leads for all distances (p < 0.005)., Conclusions: Overall, myopes tended to accommodate less than emmetropes, irrespective of the contact lens type, which significantly affected accommodation for both groups. The apparent over-accommodation of myopes when wearing the BF contact lenses may explain the reported efficacy as a myopia control treatment, although further studies are required to elucidate the mechanism underlying this accommodative effect.

- Abstract
Maximizing the response rate to surveys involves thoughtful choices about survey design, sampling and collection methods. This paper describes an innovative survey method, to provide immediate reinforcement for responding and to minimize the response cost. This method involves using a questionnaire printed as checks on security (anti-fraud) paper with questions and responses separated using a perforated tear off section. Once a participant completes the survey, the response area is detached from the questions, thus protecting the confidentiality of the subject, and the check is returned via the banking system. This report describes the survey-check methodology, the survey flow process, and the results from four research studies which have used this method. These studies include (1) a technology accessibility survey of parents with children enrolled in a low-income preschool program; (2) a parent report of their child's behavior used as screening criteria for inclusion in a computer-mediated parent education project; (3) a follow-up questionnaire as part of a longitudinal study of child behavior, covering home and classroom interventions, and service utilization, and; (4) a survey of dentists in support of efforts to recruit them to participate in a randomized control trial of tobacco cessation in dental offices. The results of using this method show great improvement in response rates over traditionally administered surveys for three of the four reported studies. Results are discussed in terms of future applications of this method, limitations, and potential cost savings.

- Abstract
Nicotine lozenges have been shown to increase tobacco abstinence rates in cigarette smokers, but they have not been evaluated in smokeless tobacco (ST) users. We conducted an open-label, one-arm, phase II clinical trial to evaluate the efficacy of the 4-mg nicotine lozenge for the treatment of withdrawal and craving associated with tobacco abstinence among ST users. Eligible subjects received 4-mg nicotine lozenges for 6 weeks followed by a 6-week taper. Subjects completed daily tobacco withdrawal diaries, and data on lozenge use, adverse events, and lozenge acceptability were collected. Urine anabasine was collected at 3 and 6 months for biochemical confirmation of self-reported tobacco abstinence. Participants were 30 ST users with a mean age of 35.4 years (SD=6.5) using an average of 4.2 cans or pouches (SD=3.2) of ST per week for a mean of 15.1 years (SD=6.5). Among subjects continuously tobacco abstinent for the first 2 weeks, no significant increases in composite withdrawal symptoms were observed, compared with baseline symptoms, whereas craving decreased significantly. Biochemically confirmed 7-day point-prevalence tobacco abstinence was 53% (95% CI=34%-72%) at 12 weeks (end of treatment) and 47% (95% CI=28%-66%) at 6 months. Few adverse events attributable to the nicotine lozenge occurred, and the lozenge was perceived as helpful in assisting subjects quit ST. The use of the 4-mg nicotine lozenge appears promising for the clinical treatment of withdrawal symptoms and craving associated with tobacco abstinence in ST users. Future phase III clinical trials investigating the efficacy of nicotine lozenges are warranted.

- Abstract
This article reports the results of a pilot intervention to improve the social skills and literacy preparation of behaviorally at-risk Head Start children. Teachers in eight Head Start classrooms in two Oregon communities participated during the 2002-03 school year. Children in eight classrooms were screened and identified for participation using the Early Screening Project (ESP). Participants (n=16) were randomly assigned to receive social skills training, First Step to Success, social skills plus literacy training, Early Literacy Essentials, or to a comparison condition. Participants in the two intervention groups were combined and compared with the comparison group. Results indicated statistically significant gains in social skills outcomes for the intervention group. However, parent ratings of social skills showed superior effects for the comparison group as well. Receptive vocabulary, as measured by the Peabody Picture Vocabulary Test (PPVT), yielded a large effect size (Cohen's d=.95) for the intervention group. Findings suggest that a combined intervention addressing literacy and social skills, shows promise and is worthy of further development and evaluation.

- Abstract
Tobacco cessation knowledge, attitudes, and behaviors of dentists participating in a large national managed care dental plan were assessed using a mailed survey. The survey was administered to dentists recruited to participate in an evaluation of a CD-ROM and supportive electronic detailing to promote increased tobacco cessation activities. General dentists who met specific technological criteria, had an active E-mail account, and at least 200 adult patients were eligible to participate in this study. A total of 184 dentists, located in 29 states, agreed to participate. The survey instrument included questions that addressed (a) Ask, Advise, Assess, Assist, and Arrange behaviors, (b) self-efficacy including knowledge, confidence, and success regarding tobacco cessation, (c) success of various tobacco cessation strategies, (d) barriers to tobacco cessation, and (e) demographics including year of graduation, gender, and race/ethnicity. Self-reported baseline tobacco intervention-related behaviors were low, with 28% of dentists reporting that they asked their patients about tobacco or recorded tobacco use in their patients' charts at least 41% of the time. For Advise behavior, approximately half of the dentists advised tobacco-using patients to quit at least 41% of the time. Although self-reported lack of knowledge was high, 71% of respondents indicated that their lack of knowledge was either not a barrier or a slight barrier to incorporating tobacco cessation into their practices. The survey revealed that dentists do not routinely incorporate tobacco cessation into their practices. Newer information-transfer technologies may serve as vehicles for increased smoking cessation activities by dentists.

- Abstract
In this study we determined urine concentration of the tobacco alkaloids anabasine and anatabine, nicotine and its metabolites cotinine, and nornicotine in 99 cigarette smokers and 205 smokeless tobacco users. We also investigated the possibility that anabasine and anatabine can be used as biomarkers for tobacco use during nicotine replacement therapy. Urine samples and data on self-reported tobacco use were obtained from subjects enrolled in tobacco cessation programs. Urine concentrations of tobacco alkaloids and metabolites were measured and correlated with self-reported tobacco use. Concentrations of anabasine and anatabine were used to validate abstinence in smokeless tobacco users who used nicotine gum as part of the therapy. Correlations of alkaloid concentration with self-reported tobacco use before treatment ranged from fair to poor. In subjects abstaining from smokeless tobacco but using nicotine gum, anabasine and anatabine levels were below the cut-point of 2 ng/ml despite high concentrations of nicotine and cotinine resulting from nicotine gum use. Anabasine and anatabine concentrations in urine can be used to validate abstinence or measure the extent of tobacco use in persons undergoing nicotine replacement therapy.
