Manufacturing and the new ANSI S2.70-2006 hand,arm vibration exposure standard

HUMAN FACTORS AND ERGONOMICS IN MANUFACTURING & SERVICE INDUSTRIES, Issue 6 2008
Donald E. Wasserman
Since 1918, hand,arm vibration (HAV) exposure, principally from but not limited to vibrating power tools and processes, affects some 1.5 to 2 million regularly exposed U.S. workers and many more worldwide. These HAV exposures usually lead to an irreversible disease of the fingers/hands called hand,arm vibration syndrome whose prevalence is as high as 50% in exposed worker populations. HAVS results not only in hand,arm deterioration, but invariably job loss. To help combat the mounting HAV problem, domestic and international consensus HAV exposure standards were developed and promulgated in the early 1980s; but for the first time, the European Union in 2005 passed into law exposure standards for both HAV and whole-body vibration. In response, in 2006 in the United States, the American National Standards Institute (ANSI) developed, replaced, and promulgated its 1986 HAV exposure standard S3.34 with a completely revised HAV standard,S2.70-2006,thus ushering in new profound implications for power tool users and tool manufacturers and countless related manufacturing operations throughout the United States. The background, salient aspects, safety and health, and manufacturing implications of this new ANSI S2.70 HAV standard are discussed. © 2008 Wiley Periodicals, Inc. [source]


The influence of education on the interpretation of pharmaceutical pictograms for communicating medicine instructions

INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 1 2003
Ros Dowse senior lecturer
Objective To assess the influence of formal education on the interpretation of pharmaceutical pictograms. Method A total of 46 pictograms were used: 23 were extracted directly from the USP-DI, and 23 with corresponding meanings were designed in accordance with the local culture (local pictograms). One hundred and thirty Xhosa respondents, who ranged from having no formal education to tertiary level education, were interviewed with the aid of an interpreter. Demographic data were collected, a literacy test was conducted and respondents were tested for their interpretation of all 46 pictograms. Preference for either the USP-DI or the local pictogram was determined. Setting Respondents were interviewed in primary health care clinics, a variety of work settings or in their homes in Grahamstown, South Africa. Key findings Standard of education had a significant influence on the interpretation of 24 of the 46 pictograms. Generally, significant differences in interpretation were apparent between those with only primary school education and those who had completed at least some senior school education (P < 0.05). The group with tertiary education was significantly better than the other groups (P < 0.05). Only 15 of the 46 pictograms met the American National Standards Institute (ANSI) 85% correct criterion. Conclusion Interpretation was dependent on education and the development of visual literacy skills, but potential for misinterpretation in all educational groups was noted. These results suggest that pictograms should only be used as a communication aid in combination with text or verbal information from the health care provider. [source]


Antifungal susceptibility testing by flow cytometry: is it the future?

MYCOSES, Issue 4 2006
Luís André Vale-Silva
Summary The current increase in the number and significance of fungal infections, the expanding armamentarium of antifungal agents, and the emergence of the problem of antifungal drug resistance have been intensifying the importance of antifungal susceptibility testing (AST). The Clinical and Laboratory Standards Institute (CLSI, formerly NCCLS) in the United States and the Antifungal Susceptibility Testing Subcommittee of the European Committee on Antimicrobial Susceptibility Testing (AFST-EUCAST) published standard methodologies in order to achieve higher reproducibility and allow direct inter-laboratory comparison of the susceptibility results. Nevertheless, several problems remain unresolved and the methods depend on long incubation periods of a minimum of 24 h (EUCAST) or even 48 h (CLSI). Over the last 15 years, successful applications of flow cytometric techniques to AST of both yeast and moulds have been reported. These techniques are based on the analysis of a great number of fungal cells individually and frequently rely on short incubation times of no more than a few hours. Considering these attributes, flow cytometry (FC) seems to have the potential to achieve clinical usefulness in the near future. The collection of data on the reproducibility of the results and on the correlation with clinical outcomes has barely started, however. Practical validation of the experimental methodologies is not granted before a significant amount of data addressing those questions is available. [source]


Prevalence and resistance patterns of extended-spectrum and AmpC ,-lactamase in Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Salmonella serovar Stanley in a Korean tertiary hospital

Park SD, Uh Y, Lee G, Lim K, Kim JB, Jeong SH. Prevalence and resistance patterns of extended-spectrum and AmpC ,-lactamase in Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Salmonella serovar Stanley in a Korean tertiary hospital. APMIS 2010; 118: 801,8. A total of 100 clinical isolates of Escherichia coli (n = 35), Klebsiella pneumoniae (n = 63), Proteus mirabilis (n = 1), and Salmonella serovar Stanley (n = 1), showing resistance to cefoxitin, or returning positive in extended-spectrum ,-lactamase (ESBL) by Clinical and Laboratory Standards Institute (CLSI) ESBL confirmatory method, were studied. The isolates were examined by the boronic acid (BA) disk test, polymerase chain reaction, and pulsed-field gel electrophoresis (PFGE) to investigate genetic similarities. The concurrence rates for ESBLs by the CLSI and the BA disk test were 97% for E. coli and 96.7% for K. pneumoniae. A total of 41 isolates showing cefoxitin resistance yielded all positive by the BA disk test. All the 33 K. pneumoniae isolates, which showed positive by the BA disk test, were carrying AmpC genes. The TEM and CTX-M types were predominant in E. coli and the SHV and the CIT and/or DHA types were predominant in K. pneumoniae. PFGE analysis showed almost 75% of genetic similarities among K. pneumoniae isolates producing ESBLs and/or AmpC ,-lactamases (AmpCs) as each K. pneumoniae carried variable genes and showed variable antibiotic patterns. Clearly, the BA disk test was a useful method for the detection of ESBLs and AmpCs. In particular, cefoxitin resistance and BA-positive trait of K. pneumoniae do reflect the presence of AmpC genes in the organism. [source]


Exploratory evaluation of several teratogen warning symbols,

BIRTH DEFECTS RESEARCH, Issue 6 2006
Richard Goldsworthy
Abstract BACKGROUND: Previous research has noted potential inadequacies in the warning labels and symbols used with some teratogenic medications. A clear teratogen warning symbol represents an important component of risk mitigation for accidental teratogen exposure. METHODS: Several teratogen warning symbols were developed through rapid prototyping and focus groups. A nationally distributed field trial (n = 300) examined the relative effectiveness of 6 candidate symbols, including the symbol in use at the time of the study. Measures included open-ended interpretation, closed-ended preference, and demographic surveys. Each participant was shown a single symbol and asked what it meant, to whom it applied, and what that person should do. Text statements were added to the symbol and participants were asked to reinterpret the warning. Participants were told the intended message of the warning, shown all 6 symbols, and asked to choose the most effective symbol. RESULTS: Four of 6 symbols achieved levels of correct interpretation close to or exceeding the American National Standards Institute (ANSI) benchmark of 85% and none exceeded the ANSI limit of 5% critical confusion. Symbols elicited varying conceptual responses. Respondents considered 1 symbol to be the most effective, by a 4 to 1 margin. Several outcomes varied by age and by ethnicity. CONCLUSIONS: Several symbols emerged as viable alternatives to the current symbol; however, no 1 symbol was clearly found to be the most effective. Instead, the symbol considered "best" depends on the messages that are considered most essential to the warning. Additionally, it appears a symbol without the addition of text can convey most, but possibly not all, of the meaning required of the warning label. Next steps should include further symbol refinement, closer examination of text additions to symbols, and validation of the candidate symbols and warnings through a large-scale field trial.
