{"title":"Role of surveillance cultures in prevention and treatment of fungal infections.","authors":"T J Walsh","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Fungal surveillance cultures have been studied as potential predictors of invasive or disseminated mycoses. Several studies have demonstrated that the presence of Candida tropicalis in mucosal surveillance cultures has a high predictive value for invasive fungal infection due to this pathogen in granulocytopenic patients. By comparison, surveillance cultures for Candida albicans have a poor positive predictive value for invasive fungal infection. The value of routine surveillance cultures of the nares for Aspergillus spp. has not been consistently confirmed. The use of surveillance cultures for less common fungal pathogens, such as Trichosporon beigelii, also remains unclear. Fungal surveillance cultures of the inanimate hospital environment have proven useful in identifying the source of conidia in well-defined clusters or outbreaks of nosocomial aspergillosis and other mycoses. As investigational tools, fungal surveillance cultures also may be useful for studying the effects of new antifungal agents on mucosal flora. Fungal surveillance cultures, especially for C. tropicalis and possibly Aspergillus spp. in high-risk populations, may be useful when a pathogen-directed approach to antifungal therapy is used. However, the time required, diagnostic limitations, and expense of routine mucosal fungal surveillance cultures must be balanced against the effect of this information on therapeutic decisions. Empirical antifungal therapy and early diagnostic approaches for high-risk patients may obviate the need for routine fungal surveillance cultures while decreasing the frequency of invasive mycoses.</p>","PeriodicalId":77576,"journal":{"name":"NCI monographs : a publication of the National Cancer Institute","volume":" 9","pages":"43-5"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13491677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Advertising and promotion of smokeless tobacco products.","authors":"V L Ernster","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>This paper is focused on the approaches used to advertise and promote smokeless tobacco products during the early to mid-1980s. These included traditional motifs that featured rugged-looking masculine models in sporting and outdoor settings as well as an expanded white-collar appeal. Smokeless tobacco was not affected by the ban on broadcast advertising of cigarettes that went into effect in 1971, and, until 1986, both print and broadcast media were used to advertise it. Promotional activities ranged from sponsorship of sporting events to offers for clothing bearing smokeless tobacco product logos. Despite the claims of manufacturers that advertising and promotional efforts were not targeted to youth, smokeless tobacco companies sponsored tobacco-spitting contests with teenage participants, a college marketing program, and college scholarships. In efforts that appeared designed to bolster their public image in the face of growing concern over the consequences of smokeless tobacco use by young people, companies like U.S. Tobacco Company contributed to major social programs, including, ironically, alcohol- and drug-abuse prevention programs. Spurred by public health groups, federal legislation was passed in 1986 that banned television and radio advertising of smokeless tobacco products and required manufacturers to include warning labels on their products on the potential health hazards of smokeless tobacco use.</p>","PeriodicalId":77576,"journal":{"name":"NCI monographs : a publication of the National Cancer Institute","volume":" 8","pages":"87-94"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13796016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The occurrence of events in the smoking onset process are strongly related to increases in the subsequent onset rate for smokeless tobacco use.

There were 6- and 12-month follow-ups to the initial questionnaire. Substantial levels of tobacco, alcohol, and marijuana use were reported, with 21% reporting use of more than one drug in the last week. Daily smokeless tobacco users were more likely to initiate use of cigarettes, marijuana, and alcohol than were other males. In addition, the \"having used\" smokeless tobacco variable was related to increased use of cigarettes, marijuana, and alcohol at follow-up. Discriminant analysis of concurrent data identified peer use of smokeless tobacco and experience with cigarette smoking as the primary discriminating factors between males who had tried it and those who had not. Peer use of smokeless tobacco also discriminated between daily users and those who had tried it but had not gone on to become daily users. Thus peer influence seems to be an important factor not just in trial of smokeless tobacco but also in the development of a daily use pattern.
