Evaluation of a smoking cessation program implemented in the workplace

BACKGROUND: Acute abdominal pain due to complicated Meckel's diverticulum is an unusual event. Even the presence of biliary enterolithiasis at the onset of inflamed congenital diverticulum has rarely been reported previously. RESULTS: Despite this unusual presentation, an episode of gallstone passage through the biliary tract has not yet been described. CONCLUSIONS: Whether the stones were primarily formed in the diverticulum as enterolithiasis, or secondary to gallstone passage is discussed. The complications of Meckel's diverticulum requiring surgical treatment are reviewed, focusing on the unusual finding of biliary stones in Meckel's diverticulum and the etiogenic mechanism of enterolithiasis.     

Effectiveness of a worksite smoking cessation program in the military. Program evaluation

1. A program evaluation was conducted to evaluate the effectiveness of the smoking cessation program. Substantiating data enhances the value of health promotion programs as key components of the health care delivery system. 2. Persons enrolled in the 8 week smoking cessation program and members of a comparison group were administered an evaluation tool prior to participating in the program, with a second evaluation tool upon completion of the program. Afterward, the smoking status of the members of both groups was evaluated at 3 month intervals for a period of 1 year. 3. Of the participants, 26.7% were not smoking 12 months after the program, compared to 6.9% of the comparison group. Of those participants who resumed smoking, 64% smoked less than half the amount they smoked before taking the class.     

Strategies for smoking cessation

Smoking cessation strategies should be geared to the target group's level of motivation to quit, and degree of tobacco addiction. Motivational interventions (e.g. media campaigns) aim to encourage more people to try to stop smoking. Treatment interventions (e.g. nicotine replacement) aim to increase the chances of a quit attempt being successful. In populations which have already been saturated by motivational interventions, the overall effect of adding further motivational interventions may be rather small, and possibly non-existent in heavy smokers. As a population's smoking prevalence declines, so the balance of interventions should shift from motivational to treatment approaches. Nicotine replacement is an effective smoking cessation aid and should form the basis for treating moderate to heavy smokers. There may be a case for the development of more specialist clinics to treat motivated but addicted smokers and train health professionals how to apply effective smoking cessation methods as part of their routine work.     

Cigarette smoking under stress: the role of coping expectancies among smokers in a clinic-based smoking cessation program

This study examined 2 expectancies to explain smoking under stress: smokers' expectations about their ability to cope with stress while remaining abstinent and their expectations about the stress-ameliorating and coping benefits of smoking under stress. The interaction of the expectancies concurrently predicted smoking urge under stress, which, in turn, predicted subsequent smoking. The interaction of posttreatment expectancies prospectively predicted smoking status 3 months after treatment, although the coping benefits of smoking expectancy effect was reversed. Expectations about coping ability increased and expectations about the coping benefits of smoking decreased as a function of participating in a smoking cessation program. The discrepant concurrent and prospective findings, reasons that coping expectancies are associated with smoking under stress, and treatment implications are discussed.     

Computerized smoking cessation program for the worksite: Treatment outcome and feasibility.

This study demonstrated the effectiveness of a computer-delivered smoking cessation program for the worksite. 58 VA Medical Center employees were randomly assigned to a computer group (computerized nicotine fading and stop-smoking contest) or a contest-only group. In comparison with the contest-only group, the computer group had nonsignificantly higher abstinence rates across follow-up, had marginally lower CO levels at the 3- and 6-month follow-ups, and smoked cigarettes with lower nicotine levels at the 10-day and 6-month follow-ups.

Promoting smoking cessation among cancer patients: a behavioral model

The smoking cessation clinical practice guideline recently published by the Agency for Health Care Policy and Research (AHCPR) summarizes current knowledge on smoking cessation treatments. Among its recommendations, the guideline encourages physicians to motivate patients who indicate that they are not yet ready to quit smoking. Because medical training typically emphasizes pharmacologic rather than behavioral treatment, we believe that physicians caring for cancer patients may benefit from more extensive instruction in motivating patients to quit smoking. This article describes how a contemporary theoretical approach, the transtheoretical model of change, can be used to promote behavioral change. Multiple studies, primarily in the field of smoking cessation, provide strong empiric support for use of this model in clinical practice. The model consists of five stages of smoking cessation that describe different levels of readiness to quit: precontemplation, contemplation, preparation, action, and maintenance. A diagnostic tool is presented, and specific smoking cessation counseling strategies are suggested for each stage of change. Implications for the use of the model by physicians who counsel and treat smokers are discussed.     

Predictors of quitting and dropout among women in a clinic-based smoking cessation program.

Most cessation studies assume that dropouts are smokers. Instead, the authors analyzed these outcomes separately using multinomial regression to model the relative risk of quitting versus continued smoking and dropping out. Female (N = 281) smokers were randomly assigned to a 12-week smoking cessation program plus either a 3-times-per-week exercise program or a contact control wellness program. Higher body mass index and longer prior quit attempts predicted cessation. Self-efficacy was associated with a lower likelihood of dropout. Greater nicotine dependence and lower education predicted continued smoking or dropout versus quitting among exercisers. Patterns of smoking, dropping out, and quitting between Weeks 5 and 12 were different between exercisers and controls. Dropouts should be considered as a separate category from smokers.

Buspirone use for smoking cessation

The results of buspirone efficacy have been inconsistent and contradictory. The rate of smoking abstinence has been reported to range from 36% to 88% and 16% to 89% in buspirone and placebo treatment groups, respectively. Only one controlled study reported buspirone efficacy in reducing nicotine withdrawal symptoms, although it was based on a small sample population and only 4 weeks of follow-up. The most recent studies have been unable to demonstrate the efficacy of buspirone in smoking cessation or in the relief of withdrawal symptoms. A placebo-controlled, randomized trial with a large number of patients, relatively high doses of buspirone (30-60 mg/d), strict abstinence criteria, long-term follow-up, and the inclusion of smokers with general anxiety or anxiety reported in previous quit attempts is needed to further evaluate buspirone efficacy in smoking cessation and the reduction of nicotine withdrawal symptoms. The treatment effects of buspirone could then be specifically tested as a function of alleviating the anxiety component of the smoking withdrawal syndrome. Finally, buspirone may prove to be an alternative in patients unsuccessful with or unable to tolerate transdermal nicotine therapy. How buspirone compares with bupropion therapy for smoking cessation is also unknown.     

Efficacy of forced smoking cessation and an adjunctive behavioral treatment on long-term smoking rates.

This study evaluated the efficacy of a 6-week forced ban on smoking and brief behavioral counseling on long-term smoking rates. Participants were active-duty enrollees in U.S. Air Force basic military training over a 1-year period (N?=?25,996). All participants were under a 6-week ban from tobacco products, and 75% were randomized to a brief smoking cessation intervention, with the other 25% randomized to a control condition. At 1-year follow-up, 18% of smokers were abstinent; women, ethnic minorities, and those intending to stay quit at baseline were more likely to be abstinent. Among smokers not planning to remain abstinent at baseline, those receiving the intervention were 1.73 times more likely to be abstinent. Over time, substantial smoking initiation occurred among nonsmokers (8% of never smokers, 26% of experimental smokers, and 43% of ex-smokers). Forced cessation is associated with good levels of long-term cessation, and brief behavioral interventions enhance cessation in certain subgroups.

The role of weight concern and self-efficacy in smoking cessation and weight gain among smokers in a clinic-based cessation program

We have previously reported that Vicia graminea lectin (VGA)- and Vicia unijuga lectin (VUA)-binding glycoproteins (Vgu glycoproteins), malignant tumor-associated antigens, exist in human meconium and amniotic fluid. To examine the origin of Vgu glycoprotein, their presence, some of their chemical and serological properties and their biosynthesis in the human fetal membrane, amnion and chorion laeve and accompanying membrane cells were examined. Perchloric acid-soluble fractions were prepared from human amnion and chorion laeve, after which VUA-binding components (Vgu glycoproteins) were separated by HPLC and affinity chromatography using immobilized VUA. Biosynthesis of the antigens in primary cultured cells prepared from the amnion and chorion laeve were examined by pulse-labeling and immunoprecipitation using immobilized VUA and compared with those in cultured human cancer cells. The results indicated that the serological properties of VUA-binding components in fetal membranes were similar to those of meconium and amniotic fluid, that many molecular species of VUA-binding components were synthesized in amnion and chorion laeve cells and that about 40-50% of antigens synthesized are secreted from cells while antigens synthesized in cultured cancer cells human were hardly secreted with more than 95% of the antigens remaining in the cells. From these results, we concluded that a large part of Vgu glycoproteins found in amniotic fluid is synthesized in cells of the amnion and chorion laeve and secreted into the fluid, and that Vgu glycoproteins synthesized in cancer cells were not secreted, rather they were retained in the cells.     

Self-help interventions for smoking cessation.

Self-help interventions for smoking cessation are an important bridge between the clinical and public health approaches to smoking cessation. The current literature on self-help interventions is encouraging but incomplete. Although their quit rates are lower than those of more intensive programs, self-help interventions could have a large public health impact because of their potential for widespread distribution. Studies comparing self-help to more intensive treatment suggest that long-term cessation rates for self-help programs are potentially as high as rates for face-to-face interventions, with lower quit rates for self-help programs that are likely due to differences in program adherence. Tailored materials and personalized adjuncts (e.g., written feedback or telephone counseling) that promote program adherence may increase cessation rates.

The effect of five smoking cessation pharmacotherapies on smoking cessation milestones.

Objective: Most smoking cessation studies have used long-term abstinence as their primary outcome measure. Recent research has suggested that long-term abstinence may be an insensitive index of important smoking cessation mechanisms. The goal of the current study was to examine the effects of 5 smoking cessation pharmacotherapies using Shiffman et al.'s (2006) approach of examining the effect of smoking cessation medications on 3 process markers of cessation or smoking cessation milestones: initial abstinence, lapse, and the lapse–relapse transition. Method: The current study (N = 1,504; 58.2% female and 41.8% male; 83.9% Caucasian, 13.6% African American, 2.5% other races) examined the effect of 5 smoking cessation pharmacotherapy treatments versus placebo (bupropion, nicotine lozenge, nicotine patch, bupropion + lozenge, patch + lozenge) on Shiffman et al.'s smoking cessation milestones over 8 weeks following a quit attempt. Results: Results show that all 5 medication conditions decreased rates of failure to achieve initial abstinence and most (with the exception of the nicotine lozenge) decreased lapse risk; however, only the nicotine patch and bupropion + lozenge conditions affected the lapse–relapse transition. Conclusions: These findings demonstrate that medications are effective at aiding initial abstinence and decreasing lapse risk but that they generally do not decrease relapse risk following a lapse. The analysis of cessation milestones sheds light on important impediments to long-term smoking abstinence, suggests potential mechanisms of action of smoking cessation pharmacotherapies, and identifies targets for future treatment development.

Stage of quitting and motivational factors relevant to smoking cessation program choices.

Conducted analyses of product involvement, a motivational construct discussed in consumer research literature. Data are presented on the relationships among cessation program involvement, stage of quitting, and cessation program attribute preferences associated with extrinsic motivation. Results from 218 smokers suggest that smokers have a strong but not exclusive preference for program features associated with extrinsic motivation, even in later stages of quitting. A preference for these features was more pronounced in smokers with lower levels of cessation program involvement. Smokers in the contemplator stage were the most likely to show higher levels of involvement. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Family physicians'' utilization of a brief smoking cessation program following reinforcement contact after training: a randomized trial

Viral infections may induce an acquired form of immunodeficiency, generally lasting a few weeks. In the more severe form, such as HIV infection, the immunodeficiency is permanent. Programmed death of T cells represents one of the mechanisms by which HIV determines the T cell functional impairment, finally resulting in the destruction of T cells. In this study, we evaluated whether an altered regulation of apoptosis was also implicated in the anergy associated with the common measles or varicella-zoster virus (VZV) infections in infancy. A spontaneous apoptosis of peripheral blood mononuclear cells was observed in children who had suffered from these infections as long as 6 mo after the acute disease. Apoptosis was demonstrated through analysis of cellular DNA content, morphologic evidence of cell nuclei shrinkage, and by analysis of DNA degradation. Stimulation of T cells through anti-CD4 MAb increased the number of apoptotic cells with a maximal effect 72 h after the stimulation. Our results suggest that apoptosis may account for the anergy that follows acute viral infections in infancy.     

Self-efficacy for recovery from a lapse after smoking cessation.

Self-efficacy for avoiding any lapse after smoking cessation has often been found to predict maintaining abstinence. The authors measured recent ex-smokers' self-efficacy for recovery of abstinence (SER) after an initial lapse by using the articulated thoughts during simulated situations (G. C. Davison et al, 1983) paradigm. Ss with moderate SER maintained abstinence nonsignificantly longer than did those with high SER, significantly longer than those with low SER. This result is consistent with A. Bandura's (1986) hypothesis that SER should be high enough that ex-smokers do not become hopeless if a lapse occurs, yet not so high that they are tempted to experiment with smoking. The discussion focuses on measurement and conceptualization of SER, in particular its distinctiveness from response–outcome expectations.

Optimizing smoking cessation strategies

Smoking cigarettes remains the leading cause of preventable illnesses and premature deaths in the United States. Although approximately half of living Americans who have ever smoked have quit, recent studies show that more than 70% of current smokers would like to stop smoking. Health care providers can enhance smoking cessation in their clients by performing assessments of both the physical and psychologic addictive aspects of smoking as well as past and current cessation barriers. Based on the assessment, the clinician should formulate a treatment plan by individualizing appropriate education, counseling, motivation, and pharmacologic support. This article reviews the prevalence and hazards of smoking and supplies health care providers with interventions to assist clients in becoming and remaining nonsmokers.
