Role of cytotechnologists in rapid onsite adequacy assessment of cytology materials for diagnostic workup and specimen allocation for ancillary testing using a standardized protocol.

INTRODUCTION: Data on the performance of cytotechnologists in assessing specimen adequacy of needle core biopsies (NCB) is scant and their role in specimen triaging for ancillary studies have not been well established. MATERIALS AND METHODS: We retrospectively analyzed rapid onsite evaluation (ROSE) performed exclusively by cytotechnologists on 248 NCB and fine-needle aspiration (FNA) specimens. Overall adequacy and accuracy rates were determined by comparing to final diagnosis. We also reviewed the process of specimen allocation for ancillary testing to determine whether specimens were appropriately triaged at the time of ROSE. RESULTS: Of the 248 cases, 222 (89.5%) were touch imprint and 26 (10.5%) were FNA smears. The overall adequacy rate was 73.4% (182 of 248). Concordance for "adequate" interpretation by ROSE with unequivocal malignant or benign diagnoses on final interpretation was 95.6%. The sensitivity, specificity, and accuracy of ROSE for a final "positive for malignancy" were 89.2% (95% CI 83.04% to 93.69%), 43.24% (95% CI 31.77% to 55.28%), and 73.87% (95% CI 67.57% to 55.28%), respectively. Cases with "positive for malignancy" on final diagnosis were "adequate" by ROSE in 89.1% (132 of 148) and "inadequate" in 10.8% (16 of 148), P < 0.0001. Ancillary tests were performed in 168 of 248 (67.7%); the majority were immunohistochemical stains for determining tumor subtype. Predictive biomarkers were performed successfully in 100% of metastatic breast cancers. CONCLUSIONS: Cytotechnologists performed at a high level of competency in providing ROSE and allocating specimens for ancillary testing, which were performed successfully in the majority of cases. Implementation of a standardized protocol for tissue management/prioritization is of paramount importance to maximize tissue preservation and minimize wastage.

Bridging the gap between science and policy: an international survey of scientists and policy makers in China and Canada.

BACKGROUND: Bridging the gap between science and policy is an important task in evidence-informed policy making. The objective of this study is to prioritize ways to bridge the gap. METHODS: The study was based on an online survey of high-ranking scientists and policy makers who have a senior position in universities and governments in the health sector in China and Canada. The sampling frame comprised of universities with schools of public health and medicine and various levels of government in health and public health. Participants included university presidents and professors, and government deputy ministers, directors general and directors working in the health field. Fourteen strategies were presented to the participants for ranking as current ways and ideal ways in the future to bridge the gap between science and policy. RESULTS: Over a 3-month survey period, there were 121 participants in China and 86 in Canada with response rates of 30.0 and 15.9 %, respectively. The top strategies selected by respondents included focus on policy (conducting research that focuses on policy questions), science-policy forums, and policy briefs, both as current ways and ideal ways to bridge the gap between science and policy. Conferences were considered a priority strategy as a current way, but not an ideal way in the future. Canadian participants were more in favor of using information technology (web-based portals and email updates) than their Chinese counterparts. Among Canadian participants, two strategies that were ranked low as current ways (collaboration in study design and collaboration in analysis) became a priority as ideal ways. This could signal a change in thinking in shifting the focus from the "back end" or "downstream" (knowledge dissemination) of the knowledge transfer process to the "front end" or "upstream" (knowledge generation). CONCLUSIONS: Our international study has confirmed a number of previously reported priority strategies to bridge the gap between science and policy. More importantly, our study has contributed to the future work on evidence-based policy making by comparing the responses from China and Canada and the current and ideal way for the future. Our study shows that the concept and strategies of bridging the gap between science and policy are not static but varying in space and evolving over time.

Awareness and practice of safety precautions among healthcare workers in the laboratories of two public health facilities in Nigeria.

AIMS AND OBJECTIVES: To determine the level of awareness and practice of SP among laboratory workers at two tertiary public health facilities in Nigeria. METHODS: A semi-structured, self-administered questionnaire was used to assess the awareness, attitude and adherence to SP among laboratory workers. Information on the availability of safety equipment was also sought. The laboratory safety practice of respondents was assessed based on self-reported observance of basic principles of universal precautions in clinical settings. RESULTS: Study participants were 130, mean age: 28.2 years (SD±6.6), number of years in hospital employment: 3.7 years (SD±2.4) and the male to female ratio was 1.8:1. Many (41.5%) were unaware and 25.4% do not observe SP. Participants attest to availability of various safety devices and equipment including hand gloves (86.2%), disinfectants (84.6%), HBV immunisation (46.2%) and post exposure prophylaxis (PEP) for HIV and HBV (79.6%). Attitude to safety is unsatisfactory as 60.0% eat and drink in the laboratory, 50.8% recap needles and 56.9% use sharps box. Even though 83.1% are willing to take PEP, only 1.5% will present self following laboratory injury. CONCLUSION: This study shows the deficit in the awareness of SP among laboratory personnel and demonstrates that attitude and practice of safety rules are unsatisfactory. Training and re-training on SP is therefore desired. Counselling to induce a positive attitudinal change on HBV immunisation and PEP is similarly necessary.

Using qualitative methods to investigate risk perception of Canadian medical laboratory workers in relation to current prion disease infection control policies.

The aim of this study was to determine the rationale, methodology, and progress of risk perceptions of laboratory workers in relation to existing prion disease infection control policies in Canadian medical laboratories. This study developed a Web survey that investigated the knowledge, behavior, and attitudes of laboratory staff in order to (1) identify strengths, weaknesses, and gaps of current prion infection prevention and control guidelines and (2) inform the development of national medical lab specific guidelines. The use of qualitative methods to develop a relevant survey is described and future research activities are outlined. Preliminary, qualitative data indicate that, among laboratory staff, there is a high degree of perceived susceptibility toward prion transmission in medical laboratories. Significant barriers to following existing prion infection control guidelines are reported with few benefits of following these guidelines. As a result, laboratories take precautions above those that are required when processing suspect prion-infected specimens, which may result in testing delays. A focused survey for laboratory staff that addresses these issues will provide insight on the necessary steps that will ensure safe and efficient diagnostic testing for suspect prion specimens.

Graphical methods and Cold War scientific practice: the Stommel Diagram's intriguing journey from the physical to the biological environmental sciences.

In the last quarter of the twentieth century, an innovative three-dimensional graphical technique was introduced into biological oceanography and ecology, where it spread rapidly. Used to improve scientists' understanding of the importance of scale within oceanic ecosystems, this influential diagram addressed biological scales from phytoplankton to fish, physical scales from diurnal tides to ocean currents, and temporal scales from hours to ice ages. Yet the Stommel Diagram (named for physical oceanographer Henry Stommel, who created it in 1963) had not been devised to aid ecological investigations. Rather, Stommel intended it to help plan large-scale research programs in physical oceanography, particularly as Cold War research funding enabled a dramatic expansion of physical oceanography in the 1960s. Marine ecologists utilized the Stommel Diagram to enhance research on biological production in ocean environments, a key concern by the 1970s amid growing alarm about overfishing and ocean pollution. Before the end of the twentieth century, the diagram had become a significant tool within the discipline of ecology. Tracing the path that Stommel's graphical techniques traveled from the physical to the biological environmental sciences reveals a great deal about practices in these distinct research communities and their relative professional and institutional standings in the Cold War era. Crucial to appreciating the course of that path is an understanding of the divergent intellectual and social contexts of the physical versus the biological environmental sciences.

What does it mean to go public? The American response to Lysenkoism, reconsidered.

The American response to Lysenkoism took place at a crucial moment in the evolving relationship between science and the public. Like many professional scientific organizations in the early Cold War, the Genetics Society of America (GSA) resisted involvement in political issues. In contrast to similar societies in the physical sciences, however, the geneticists' silence cannot be explained solely by the fear of financial or political repercussions. Rather, the GSA's reluctance to engage in political discussion reflected an ongoing debate within the scientific community on the proper role for professional societies in political controversy. Those geneticists who did become embroiled in the controversy did so as individuals rather than as emissaries of the profession. Geneticists H.J. Muller, L.C. Dunn, and Theodosius Dobzhansky attempted to reach the public through a variety of outlets, including books, magazines, newspapers, and the radio, but their interventions were shaped by their individual personal and political commitments. The GSA, in contrast, attempted to combat the spread of Lysenkoism with the help of a public relations firm and a Golden Jubilee celebration of the rediscovery of Mendel's laws. The messy story of the American response to the Lysenko crisis demonstrates the limits of scientists' political involvement during the early Cold War.

Self-regulation of recombinant DNA technology in Japan in the 1970s.

Recombinant DNA technology was developed in the United States in the early 1970s. Leading scientists held an international Asilomar Conference in 1975 to examine the self regulation of recombinant DNA technology, followed by the U.S. National Institutes of Health drafting the Recombinant DNA Research Guidelines in 1976. The result of this conference significantly affected many nations, including Japan. However, there have been few historical studies on the self-regulation of recombinant technologies conducted by scientists and government officials in Japan. The purpose of this paper is to analyze how the Science Council of Japan, the Ministry of Education, Science adn Culture, and the Science and Technology Agency developed self-regulation policies for recombinant DNA technology in Japan in the 1970s. Groups of molecular biologist and geneticists played a key role in establishing guidelines in cooperation with government officials. Our findings suggest that self-regulation policies on recombinant DNA technology have influenced safety management for the life sciences and establishment of institutions for review in Japan.

[The historical meaning of serological surveys as a laboratory technology applied to the immunization campaigns. The case of poliomyelitis in Spain]. / El significado histórico de las encuestas de seroprevalencia como tecnología de laboratorio aplicada a las campañas de inmunización. El caso de la poliomielitis en España.

The aim of the paper is to analyse the introduction, use and diffusion of the serological surveys, a public health technology on the borderline between epidemiology and laboratory, in connection with poliomyelitis in Spain during the Francoism period. Within the framework of the "new history" of medical technologies and innovations, the serological surveys played an important role both in the improvement of knowledge on socio-demographic distribution and the health politics arena.

"Do not eat those apples; they've been on the ground!": polio epidemics and preventive measures, Sweden 1880s-1940s.

This article will address how Swedish scientists, physicians and public health officers tried to combat the polio epidemics in the pre-vaccine era. It shows that once polio was considered as an epidemic disease the preventive measures used were based on the hindrance of other infectious diseases. It also illustrates how epidemiological and laboratory studies to some degree affected the thoughts of how polio should be prevented, and that Swedish ideas and experiences differed from those put forward in the USA.

Master of the master gland: Choh Hao Li, the University of California, and science, migration, and race.

This essay examines the origins of the relationship between Choh Hao Li and the University of California, Berkeley. Li came to the United States from China in 1935 for graduate study at the University of Michigan, but ended up enrolling at Berkeley. Over the course of the next two decades, Li went from being a foreign graduate student in chemistry on a temporary visa to an internationally recognized leader in the biochemistry of endocrinology at the head of his own laboratory and a naturalized citizen of the United States. At what was otherwise a dark time for Americans of Chinese descent, Li was garnering adulation in the popular press. He was called the "master of the master gland" for his successes both in isolating and in synthesizing pituitary hormones. Specifically, the essay explores the making of the "master of the master gland" from the perspectives of the history of science and the history of race and migration in the United States, tracing the interplay among Li's scientific work, his migrations, his career aspirations, and his legal status in the United States. A Chinese intellectual cast adrift by the shifting geopolitics of World War II and the early Cold War, Li danced delicately along the margins of membership in American society during the 1940s, only arriving at what turned out to be his final destination after careful and protracted negotiations with officials of the U.S. government, with influential members of the international scientific community, and with representatives of the University of California, Berkeley.

Manhattan transfer: lethal radiation, bone marrow transplantation, and the birth of stem cell biology, ca. 1942-1961.

This study investigates how, in the late 1940s and 1950s, fears of nuclear accidents and nuclear warfare shaped postwar radiobiology. The new and intense forms of radiation generated by nuclear reactor technology, and which would be released in the event of a nuclear war, created concerns about a public-health hazard unprecedented in form and scale. Fears of inadvertent exposure to acute and potentially lethal radiation launched a search for anti-radiation therapies, out of which emerged the new technique of bone marrow transplantation (BMT). This study analyzes the use of BMT first as a research tool to explore the biological effects of ionizing radiation, and then as an adjunct to radiotherapy for the treatment of cancer. In highlighting how BMT became the province of different research and clinical constituencies, this study develops an understanding of the forces and contingencies that shaped its development. Exploring the emergence of BMT and the uses to which it was put, it reveals that BMT remained a technique in the making -- unstable and far from standardized, even as it became both a widely used research tool and rapidly made its way into the clinic. More broadly, it casts new light on one route through which the Manhattan Project influenced postwar radiobiology; it also affords new insights into one means by which radiobiology came to serve the interests of the Cold War state. In its focus on BMT this paper provides a new perspective on the evolving relationship between radiobiology and biomedicine in the postwar period.

Psychosocial work environment of hospital workers: validation of a comprehensive assessment scale.

BACKGROUND: Studies have shown that adverse workplace factors can increase the risk of ill-health in hospital workers, but more comprehensive measures of the psychosocial work environment are needed. OBJECTIVES: To test a comprehensive and theory-based psychosocial work environment questionnaire and analyze associations with mental health in a sample of Danish hospital workers. DESIGN AND PARTICIPANTS: Questionnaire-based cross-sectional study with 343 female employees from a large Danish hospital, including patient care workers (nurses, nurse assistants, midwives) and laboratory technicians. METHODS: The psychosocial work environment was measured with 14 scales from the Copenhagen psychosocial questionnaire, version I, covering three main areas: demands at work, work organization and interpersonal relations at work. We further measured self-rated mental health and sociodemographic and employment characteristics of the participants. Cronbach's alphas, analyses of covariance, one-sample t-tests, partial correlations and linear regression models were used to analyze data. RESULTS: Of the 14 work psychosocial workplace scales 12 showed a satisfactory internal consistency (alpha>0.70). Patient care workers had more quantitative, emotional and cognitive demands (all p-values <0.001), higher work pace (p<0.001) and more role conflicts (p=0.01) than laboratory technicians, but also better work organization, including more influence at work, better possibilities for development and a higher meaning of work (all p-values <0.001). Both patient care workers and laboratory technicians had substantially higher scores on the demand scales and lower scores on the influence at work scale than the general Danish working population. Further analyses showed that high levels of demands at work and low levels of work organization and problematic interpersonal relations at work were associated with lower self-rated mental health. CONCLUSION: The Copenhagen psychosocial questionnaire is a suitable instrument to measure the psychosocial work environment of hospital workers. The comprehensive assessment of the psychosocial work environment helps tailoring interventions to the specific needs of different occupational groups.

Decision makers' and scientists' opinion about contingent valuation and choice experiments for measuring willingness to pay in health care: results from a survey in Germany.

OBJECTIVES: Assessment of willingness to pay (WTP) by contingent valuation (CV) and choice experiments (CE) is increasingly performed in economic evaluation of health care. However, the question of whether the methods for measuring WTP are acceptable to decision makers and scientists has remained largely unacknowledged. The aim of this study was to learn more about decision makers' and scientists' opinion concerning these methods. METHODS: An expert group developed a questionnaire consisting of key items that may influence the opinion about CV and CE according to the constructs "attitude toward behavior," "subjective norm," and "behavioral intention" as defined by the Theory of Reasoned Action by Ajzen and Fishbein. In a survey, seventy-seven decision makers representing key institutions in the German healthcare system and forty-two scientists in health economics completed the questionnaire. RESULTS: Scientists and decision makers in particular did not show a high intention to use methods for measuring WTP. Skepticism regarding precision of the methods and subjects' capability to imagine paying an amount of money for a certain health commodity were stated along with the assertion that the hypothetical decision-making scenario was rather a distant reality. Nevertheless, the majority of scientists and decision makers did not state rejection of the methods. CONCLUSIONS: Increasing the probability of using methods for measuring WTP in health care, the hypothetical scenarios should be made more realistic and payment vehicles should be used to help patients relate payment to a real health benefit. Moreover, an intensive discussion on the potential usefulness of CV/CE without excluding ethical concerns in comparison to existing alternatives has to be resumed.
