Phenotypic variation of Staphylococcus epidermidis isolated from a patient with native valve endocarditis.

Two colonial variants of Staphylococcus epidermidis were isolated from the valvular tissue of a patient with native valve endocarditis. In addition to differing in colonial morphology, the two variants differed in hemolysis on blood-containing media, in adherence capacity, and in the expression of certain enzymes. Under suitable conditions, both variants were themselves capable of phenotypic variation, although they differed in the rate at which variants were generated. The variants yielded identical profiles on restriction endonuclease analysis of plasmid DNA and pulsed-field gel electrophoresis of whole-cell DNA. This report suggests a possible role for phenotypic variation in coagulase-negative staphylococcal virulence. Congo red agar would be an excellent medium for studying the contribution of variation to the virulence of these organisms.

Relationships between mood around slip-up and recovery of abstinence in smoking cessation attempts.

Data are presented from 201 slip-up episodes in attempts at smoking cessation. Analysis as a function of whether the person recovered and resumed abstinence broadly confirmed previous findings. Emotions immediately before and after the slip-up episode were assessed, as were feelings about having slipped-up. Feeling bad prior to the slip-up cigarette was associated with reduced recovery. By contrast, reporting that the slip-up cigarette made the person feel worse was associated with increased recovery. Feeling bad about slipping-up was not associated with relapse, contrary to predictions from Marlatt and Gordon's theorizing about the Abstinence Violation Effect.

Predicting attempts and sustained cessation of smoking after the introduction of workplace smoking bans.

Examined predictors of smoking cessation attempts and predictors of the outcome of those attempts after the introduction of a workplace smoking ban. Smokers were surveyed in the month before the ban came into force, and variables collected at that time were used to predict outcomes 6 months later. Data from 491 respondents who were smokers at the time of the initial survey were used, and a set of potential predictor variables was chosen on both theoretical and empirical grounds. Making a cessation attempt was predicted by the strength of desire to quit and, to less extent, by not having been subject to extensive restrictions on smoking before the mandated ban, having tried to quit before, perceiving oneself high in ability to quit, and being worried about smoke at work. For the outcome of cessation attempts among those who tried, success was best predicted by low levels of a composite habit strength variable and, to less extent, by desire to quit, no previous attempts to quit, the existence of social supports for quitting, and educational status. Although cognitive variables were important in predicting attempts, they played only a minor role in predicting maintenance. Behavioral and environmental variables contributed slightly to prediction of attempts and strongly to prediction of maintenance.

Development of a strategy to encourage attendance for screening mammography.

The present study describes a method for the data-driven structuring of interventions to increase participation in screening mammography. We interviewed 668 randomly selected women from the target population of an Australian pilot screening mammography program before this Program commenced. The aims of the study were to use cross-sectional data to determine factors which predicted women's intentions regarding attendance at the Program, and on the basis of these results to develop optimal strategies to encourage attendances. Of the sample, 64% said they intended to go to the Program, while 11% were unsure. A number of variables were significantly associated with intention and regression analysis was used to determine the best model for predicting intention. Ten variables entered the final regression model: the intensity of thought about getting breast cancer; a belief that early detection is extremely desirable and that screening mammograms are accurate; having had a Pap test within the last 2 years; a belief that health is controlled by chance; perceived ease of getting to the hospital; subjective familiarity with the hospital location of the Program; age; having heard about screening mammography; and a feeling of personal susceptibility to breast cancer. This model explained 20% of the variance in intention to have a mammogram (R 2 = 0.20, F(10,492) = 12.08; P less than 0.0001). The practical applications of these findings are discussed in this report. It is recommended that if a campaign were to concentrate on changing women's perceptions on the dimensions found to be significantly associated with intention, then it would have maximum chance of encouraging attendance amongst women in the target population. The strategies we have developed based on these findings are discussed in this paper.

Centre for behavioural research in cancer.

The Centre for Behavioural Research in Cancer (CBRC) is one of two research centres housed at the Anti-Cancer Council of Victoria, the other being an epidemiological research centre. The CBRC's main focus for research is in smoking behaviour. A feature of the Centre is its close organizational and professional links with Victoria's large publicly funded smoking prevention programme. This provides opportunities to conduct programme-related research, to influence the nature of tobacco reduction interventions and to evaluate outcomes.

Cancer-related beliefs and behaviours in Australia.

A sample of 3527 adults aged 16 years and over was interviewed in their homes to obtain Australian data on selected behavioural risk factors for cancer. Four fifths of those interviewed nominated at least one step that individuals may take to reduce their risk of cancer, while 14 per cent believed there were no preventive measures available. Most salient among the preventive steps mentioned were 'not smoking' (58 per cent), dietary measures (30 per cent) and protection of the skin against the sun (13 per cent). Various psychological factors were mentioned by 7 per cent. Beliefs about dietary factors associated with cancer and the direction of the relationship tended to be accurate but there appeared to be some confusion with heart disease dietary risk factors. One third of respondents had at some time noticed a skin sign they thought might be cancer, and this was related (as expected) to latitude of residence. Nearly half had at some time systematically checked their skin for lesions, and 13 per cent said they had done this at least six times in the preceding year. Overall, 78 per cent of women respondents said they had been screened for cervical cancer, and 51 per cent said this had taken place in the past two years. Twelve per cent reported having had a mammogram, 7 per cent that were apparently diagnostic and 5 per cent that were reported to be routine screening mammograms. Overall, 78 per cent said they had done systematic breast self-examination at least once, including 41 per cent who said they had done breast self-examination in the past month and 23 per cent who reported having done it monthly over the previous year.

Changes in smoking behaviour after a total workplace smoking ban.

This paper reports data on changes in smoking behaviour after the introduction of a total workplace smoking ban in Telecom Australia. A sample of 1089 Telecom staff were surveyed in the months before the introduction of the ban and 620 were resurveyed six months after the ban had been implemented. A further sample of 1424 was drawn from the same parts of the organisation 18 months after implementation. Among the smokers in these samples, the bans produced a reduction in workday cigarette consumption of between three and four cigarettes a day and this reduction was maintained at 18 months. Over the two-year period from six months before the ban to 18 months after it, smoking prevalence dropped about 5 per cent, which we estimate is about twice the decline found in the general community. Workplace smoking bans can produce public health and can assist individual smokers to regulate their habit.

A total ban on workplace smoking is acceptable and effective.

The acceptability and effectiveness of a total workplace smoking ban in Telecom Australia was evaluated in a series of studies. Staff in a sample of representative areas were surveyed prior to the introduction of the bans, then 6 and 18 months afterward. By 18 months 81% of all staff, including 53% of smokers, approved of the bans. Sixty-six percent of staff reported a total ban was operative, and 31% reported a total ban except for a smoking room, leaving only 3% reporting lesser restrictions. Smokers were smoking between three and four less cigarettes per work day, and the numbers of smokers had decreased by about double the community rate. The policy had little perceived effect on productivity but resulted in some tension between staff that progressively decreased and now is limited to the few areas where there were problems with compliance. A subsample of managers and staff were interviewed and factors relevant to successful implementation of the policy were identified. These included a clear statement of policy, strong managerial support via equipping managers with leadership and negotiating skills, and the use of occupational health nurses. It is important to provide assistance to affected staff to help them adjust to the ban both before as well as in the months after implementation.

Changes in acceptance of workplace smoking bans following their implementation: a prospective study.

Recent cross-sectional and retrospective studies suggest that the attitudes of employees toward workplace smoking bans may become more positive after the bans have been introduced. Using a prospective design, we found that the attitudes of nonsmokers, ex-smokers, and smokers became more favorable over the 6 months following the introduction of smoking bans to Australian Government Offices. The magnitude of changes in approval ratings was greatest for smokers, but smokers were also more likely to disapprove of the bans before and after their introduction than were nonsmokers and ex-smokers. Among smokers, there was a strong relationship between the extent to which they saw themselves inconvenienced by the bans and the extent to which they disapproved of them. Overall, the bans were accepted and viewed in a positive light, but there was nevertheless a significant minority of smokers who remained disgruntled with them. Some ways in which the concerns of this subgroup of smokers may be addressed are considered.

Hygienic hand disinfection: a comparative study with chlorhexidine detergents and soap.

The efficacy of two chlorhexidine hand-wash detergents and liquid soap was compared in a laboratory trial using artificial contamination of fingers with Micrococcus and Serratia. Agents were assessed for both a rapid and sustained effect after a single contact, and for a cumulative persistent effect after multiple contact over four days. Disinfectant activities were compared by statistical analysis of log reduction factors and log count time gradients (decimal reduction times). The latter analysis attempted to accommodate significant subject variation in response to both agent and organism. All handwashing methods significantly reduced contamination levels. Both chlorhexidine formulations were significantly better than soap in their activity against Micrococcus, but were not more effective than soap in removing contamination with Serratia. Both chlorhexidine preparations showed significant skin persistence and were generally acceptable to subjects after prolonged use. Some effect of the formulation of the hand-wash on chlorhexidine activity was demonstrated.

Slip-ups and relapse in attempts to quit smoking.

This paper is concerned with documenting the contexts in which slip-ups in attempts to stop smoking occur, and of the consequences of the slip-up on the continuation of smoking cessation. A sample of people who had called a Quit Smoking telephone service for information was recontacted three months later. A total of initial 216 slip-up episodes was reported, 44 of which resulted in a resumption of abstinence and 172 which led to relapse. Slip-ups were found to occur in a broad range of contexts, and context was also related to outcome. Slip-ups when in a positive mood, when socializing and drinking alcohol were associated with higher levels of recovery of abstinence, as were those that occurred after more than two weeks of abstinence. Sex differences were also found, with men more likely to slip-up at work, and women to slip-up in a broader variety of contexts.

Two-month follow-up on callers to a telephone quit smoking service.

The results of a 2-month follow-up on a sample of individuals who rang a telephone quit smoking service to get advice on how to quit smoking are reported. Calls were in response to large-scale media campaigns carried out in Victoria each year from 1984 through 1986. The calls to the service came more from women than men and tended to come from better educated white collar workers. There were few differences in short-term quit rates as a function of basic demographic variables. There was some evidence that after 3 years of campaigning a greater proportion of telephone service users were making a major effort to quit and that younger smokers at whom the campaign was directed were more likely to quit.

Effects of workplace smoking bans on cigarette consumption.

A sample of staff working in the Australian Public Service (n = 2113) were surveyed two to four weeks before a mandated total ban on workplace smoking was introduced, and again five to six months later. Among the 391 smokers on whom complete data were available, the workplace smoking bans were associated with reduced rates of smoking, particularly among heavier smokers where the reduction in consumption was over 25 percent.

Why the tobacco industry fears the passive smoking issue.

The tobacco industry has identified the passive smoking issue as the single most important problem confronting its economic future. During the 1980s, the industry has been engaged in an elaborate and expensive international campaign seeking to refute the evidence against passive smoking's effects on health and to position the issue as one essentially concerned with civil liberties and smokers' "rights." There are three main reasons for the industry's concern: first, the passive smoking issue allows a widening of the definition of smoking beyond its discussion as a personal habit, legitimizing it as a social problem; second, successful cases of litigation against employers by workers with histories of chronic exposure to environmental tobacco smoke have created an industrial climate of concern leading to workplace smoking restrictions and bans, and third, the proliferation of smoking restrictions reduces smoking opportunities and thus reduces total cigarette consumption and hence financial returns to the industry. Based on the results of a large Australian study of a workplace smoking ban, an estimated 654.88 million cigarettes with a retail value of $A6,549 thousand would be forgone annually in Australia alone if 50 percent of white-collar worksites were to ban smoking. Finally, the passive smoking issue can be considered a Trojan horse to its less discussed effects: the reduced morbidity and mortality likely to result in smokers from the significant reductions in smoking frequency that occur with the proliferation of smoking restrictions introduced in the name of concern for the health of nonsmokers.

Staff members' acceptance of the introduction of workplace smoking bans in the Australian public service.

The acceptability to employees of workplace smoking bans is an important factor in their introduction and in subsequent compliance. This study describes the acceptance by affected staff members before the ban on smoking in Australian public-service premises. Four thousand, two hundred and fifteen (79% of those who were approached) public servants were surveyed from areas of six departments across three states. Twenty-five per cent of the sample were current smokers. Support for the bans was strong, with 76% of the sample approving over all. Approval among smokers was less, with 40% of smokers approving, compared with 82% of ex-smokers and 90% of "never" smokers. Thus, the results show a generally favourable attitudinal milieu among employees who were facing an impending ban on smoking, and far-from-unanimous opposition from smokers. Among smokers, acceptance of the bans was predictable from the attitudes towards smoking acceptance of the bans was predictable from the attitudes towards smoking in general, and from the perceived impact of the bans on smokers. The existence of restrictions on smoking at the time of the survey was associated with slightly higher levels of approval of the impending total ban, especially when the restrictions were not seen as being imposed on the respondents by others.
