Report of a workshop on respiratory viral infections: epidemiology, diagnosis, treatment, and prevention.

An international workshop to review the epidemiology, diagnosis, treatment, and prevention of respiratory viral infections was held in Turku, Finland, in May 1991. This workshop emphasized the following points. (1) In epidemiological studies of influenza virus, serological, clinical, and gene-sequencing methods have been used to produce a full picture of genetic evolution. Less complete information exists about other viruses, although new data on respiratory syncytial virus are emerging. (2) Tools for the diagnosis of respiratory viral infections have been developed in conjunction with the use of solid-phase immunoassays. A role remains for tissue culture in surveillance and epidemiological studies. Detection of bacterial involvement in respiratory infections has been more difficult. (3) Treatment of infections due to respiratory viruses has advanced with the use of amantadine and aerosolized ribavirin. On the other hand, many viruses remain refractory to treatment. Means for preventing influenza are established, but barriers to the development of other viral vaccines--including the existence of multiple serotypes, imperfect natural immunity, and paradoxical hypersensitivity--have proven difficult to surmount.

EMBO workshop report. An eclipse over the cell nucleus functional organization of the cell nucleus Prague, August 9-12, 1999.

The EMBO workshop 'Functional Organization of the Cell Nucleus' held in Prague at the Hotel of the Postgraduate School of Medicine was attended by 110 participants (49 invited speakers and 61 selected participants) from 22 countries. Such a full range of topics devoted to the cell biology of the nucleus has not been discussed previously in such an intimate meeting in Europe. The workshop not only offered an opportunity for junior scientists to benefit from having an international meeting within Europe and a chance to discuss their work with internationally recognized experts, but it also offered a unique opportunity for interactions among the more established investigators. The fruits of a number of presentations are gathered together in a Special Issue of the Journal of Structural Biology which appeared in spring 2000. Last but not least, it is worth mentioning that while stepping through a packed scientific program, the participants did find the time to observe the solar eclipse just before the lunch break of August 11.

Fantastic microbes and where to find them: evaluating learning-by-doing outcomes in a crowdfunded metagenomics workshop.

Metagenomics offers a powerful framework for authentic, interdisciplinary learning, yet it remains underrepresented in undergraduate education due to technical and infrastructural barriers. We hypothesized that a research-based, learning-by-doing metagenomics workshop supported by accessible bioinformatics tools could enhance students' perceived skills, self-efficacy, and conceptual understanding of metagenomic analysis. To test this hypothesis, we designed and evaluated a hybrid hands-on workshop in which undergraduate and postgraduate students analyzed real environmental shotgun metagenomic datasets generated from soil samples collected during a citizen science initiative. Using the graphical workflow platform KBase, participants completed an end-to-end metagenomic analysis, from quality control and assembly to genome reconstruction, taxonomic classification, functional annotation, and scientific presentation of results. Educational outcomes were assessed through validated retrospective pre-post questionnaires, self-efficacy scales, and an open-ended conceptual understanding task. Participants showed significant increases in perceived metagenomic skills and confidence in performing metagenomic analyses, while gains in perceived learning showed a positive trend. Conceptual understanding improved across educational levels, particularly among participants with limited prior experience. Together, these findings demonstrate that authentic, data-driven metagenomics activities can effectively lower barriers to computational biology and foster meaningful learning through hands-on research experiences.

The Family Stories Workshop: stories for those who cannot remember.

The Family Stories Workshop (FSW) is a process through which family members and friends of persons with dementing disorders living in nursing homes develop stories of these residents' lives. The stories are meant to help staff members to develop a better, more deeply felt understanding of the lives of the residents, persons who can no longer tell their own stories. The workshop is product-oriented and is not meant as a support group and works best in organizations emphasizing individualized care. This article describes the process of the FSW as well as outcomes from preliminary implementation. It suggests ways of using elements of the process to more broadly accomplish the FSW purposes.

Transgender HIV prevention: implementation and evaluation of a workshop.

Virtually no HIV prevention education has specifically targeted the transgender community. To fill this void, a transgender HIV prevention workshop was developed, implemented and evaluated. A 4 h workshop, grounded in the Health Belief Model and the Eroticizing Safer Sex approach, combined lectures, videos, a panel, discussion, roleplay and exercises. Evaluation using a pre-, post- and follow-up test design showed an increase in knowledge and an initial increase in positive attitudes that diminished over time. Due to the small sample size (N = 59) and limited frequency of risk behavior, a significant decrease in unsafe sexual or needle practices could not be demonstrated. However, findings suggested an increase in safer sexual behaviors such as (mutual) masturbation. Peer support improved significantly. Future prevention education should make special efforts to target the more difficult-to-reach, high-risk subgroups of the transgender population.

Primary care workshops can reduce and rationalize antibiotic prescribing.

We describe a controlled study comparing the effects on primary care prescribing in west Gloucestershire, UK, where antibiotic workshops were offered, with those in east Gloucestershire, where microbiology tutorials were given. The year-on-year changes in quantity and costs of antibiotics dispensed following general practice prescriptions were measured. There was no significant difference in the number of antibiotic items prescribed across the county, but the number of prescriptions for broad-spectrum agents (quinolones, cephalosporins and co-amoxiclav) declined by 15.4% in west Gloucestershire, compared with a 6.5% increase in east Gloucestershire (P: = 0.002). Use of narrow-spectrum antibiotics (penicillin V, trimethoprim and nitrofurantoin), whose use was encouraged, did not change in west Gloucestershire practices, but decreased by 12% in east Gloucestershire practices (P: = 0.003). There was increased use of clarithromycin and azithromycin in both groups of practices. Antibiotic workshops held in the primary care setting can rationalize antibiotic prescribing. This can reduce prescribing costs and selection pressure by broad-spectrum antimicrobial agents and, perhaps, go some way to reducing the development of resistance.

Introduction to the 3rd Amino Acid Assessment Workshop.

A series of Amino Acid Assessment Workshops (AAAWs) are being organized and conducted to bring together experts in amino acid nutrition, metabolism, cell and molecular biology, toxicology, and regulation/policy with the eventual goal to establish a paradigm for the characterization of risks associated with ingestion of specific intakes of amino acids by humans. In this brief introductory article, I present the rationale behind these AAAWs, which basically emerges from the fact that there is little systematic information about the adverse effects and the pathophysiological mechanisms of excessive intakes of single amino acids or of mixtures of amino acids in human subjects. This 3rd AAAW extends, as well as builds upon, the information collected at the 1st and 2nd AAAWs. The previous two workshops focused attention largely on the metabolism, mechanism of action, and functions of amino acids. This 3rd AAAW will focus particular attention on intakes needed to meet physiological requirements and above, host and diet factors that affect these needs and responses, as well as variation in responses to and levels of intake of amino acids among individuals. In this context, the overall objective is to establish the science and knowledge base required for use in determining and/or predicting the upper level of the safe range of intake of specific amino acids under various host, agent (diet), and environmental conditions.

Addressing the soy and breast cancer relationship: review, commentary, and workshop proceedings.

The impact of soyfood intake on breast cancer risk has been investigated extensively. Much of this focus can be attributed to the soybean being a dietary source that is uniquely rich in isoflavones. The chemical structure of isoflavones is similar to that of estrogen, and isoflavones bind to both estrogen receptors (ER alpha and ER beta) (although they preferentially bind to and activate ER beta) and exert estrogen-like effects under some experimental conditions. Isoflavones also possess nonhormonal properties that are associated with the inhibition of cancer cell growth. Thus, there are several possible mechanisms by which soy may reduce the risk of breast cancer. However, the role of isoflavones in breast cancer has become controversial because, in contrast to the possible beneficial effects, some data from in vitro and animal studies suggest that isoflavones, especially genistein, the aglycone of the main soybean isoflavone genistin, may stimulate the growth of estrogen-sensitive tumors. Limited human data directly address the tumor-promoting effects of isoflavones and soy. Because the use of soyfoods and isoflavone supplements is increasing, it is important from a public health perspective to understand the impact of these products on breast cancer risk in women at high risk of the disease and on the survival of breast cancer patients. To this end, a workshop was held in November 2005 to review the existing literature and to make research recommendations. This paper summarizes the workshop findings and recommendations. The primary research recommendation is that the impact of isoflavones on breast tissue needs to be evaluated at the cellular level in women at high risk for breast cancer.

Workshop on phase I study design. Ninth NCI/EORTC New Drug Development Symposium, Amsterdam, March 12, 1996.

Many of the methods currently used in phase I trial design date back to the 1970's. Recently, some investigators have considered whether it might be possible to perform more efficient phase I trials that minimize the number of patients treated at biologically ineffective doses, maximize the precision of recommended phase II doses, and maintain patient safety. The objective of this Workshop was to examine aspects of phase I trial design, with consideration of both standard and novel approaches. Topics included choice of starting dose level, definition of dose-limiting toxicity, development and incorporation of non-toxicity endpoints, use of alternate dose escalation schemes, and definitions of tumor response and clinical benefit, including consideration of whether these determinations from phase I studies should alter the decision to proceed to phase II drug evaluation. For each topic, this summary includes a description of the standard approach, a summary of the speaker's presentation, and commentary. The Workshop initiated discussion and reassessment that are expected to lead to testing of some of the suggested alternate approaches.

Research on first-episode psychosis: report on a National Institute of Mental Health Workshop.

The need to focus increased research on patients experiencing their first episode of psychosis was emphasized in A National Plan for Schizophrenia Research. To develop strategies for enhancing research in this area, a National Institute of Mental Health Workshop on First-Episode Psychosis was held in 1991. The topics discussed at that workshop are summarized, with key issues including the following: (1) the need for better operational definitions of onset, end of an episode, and relapse of psychosis; (2) careful consideration of inclusion and exclusion criteria related to age, gender, prior treatment, comorbid substance abuse, and similar issues; (3) the challenge of finding patients never exposed to neuroleptics and the value of entering first-episode patients into standardized treatment protocols; (4) the design of followup studies; (5) strategies to increase the pool of applicants; and (6) approaches for increasing power through data sharing and collaboration between groups.

In vitro human tissue models in risk assessment: report of a consensus-building workshop.

Advances in the technology of human cell and tissue culture and the increasing availability of human tissue for laboratory studies have led to the increased use of in vitro human tissue models in toxicology and pharmacodynamics studies and in quantitative modeling of metabolism, pharmacokinetic behavior, and transport. In recognition of the potential importance of such models in toxicological risk assessment, the Society of Toxicology sponsored a workshop to evaluate the current status of human cell and tissue models and to develop consensus recommendations on the use of such models to improve the scientific basis of risk assessment. This report summarizes the evaluation by invited experts and workshop attendees of the current status of such models for prediction of human metabolism and identification of drug-drug interactions, prediction of human toxicities, and quantitative modeling of pharmacokinetic and pharmaco-toxicodynamic behavior. Consensus recommendations for the application and improvement of current models are presented.

Workshop overview: use of genomic data in risk assessment.

The completion of the Human Genome Project has provided the foundation to analyze the expression of all genes transcribed in a specific cell, as well as a reference against which to assess genetic variability and its impact on susceptibility. Recent advances in genomic technologies have set the stage for better understanding and predicting individual adaptive and toxicological responses after toxicant exposure. Thus, it is now possible to simultaneously assess expression levels for thousands of different genes using DNA microarrays, as well as assess posttranscriptional and posttranslational events using high throughput proteomics. Similarly, the risk of toxicant exposure-induced disease used to be estimated across populations with widely varying responses. However, new high-throughput genomic technologies have the potential to greatly improve the accuracy of risk assessment, allowing identification of sensitive subpopulations at risk and ultimately leading to personalized risk profiles based on genetic composition. Recognizing the importance these technologies will have on the practice of risk assessment and the development of regulatory guidelines, the Society of Toxicology sponsored a workshop to evaluate the current status of genomic research; the ethical, legal, and social issues associated with these approaches; and, in this context, how data derived from these technologies would impact risk assessment. This article summarizes the evaluation by experts in genomic research and risk assessment in the first workshop to provide a forum for interaction between these scientific disciplines.

Workshop overview: Hepatotoxicity assessment for botanical dietary supplements.

Botanical dietary supplements (herbal products) have flooded the market in the United States over the past decade, and studies show a significant percentage of Americans use them. With increasing frequency and duration of exposure, some serious adverse effects, though relatively uncommon, have been reported. Among the most troublesome is the association of some botanicals with serious hepatotoxicity. In some cases, hepatotoxicity has been linked to the consumption of botanicals with recognized hepatotoxic components (e.g., pyrrolizidine alkaloids). However, in other cases, the causative agent(s) is less clear and, overall, the mechanisms of hepatotoxicity are poorly understood. To help create a scientific basis for understanding botanical-induced hepatotoxicity and better tools for hepatotoxicity assessment and prediction, the National Center for Natural Product Research (NCNPR) hosted a workshop (September 8 and 9, 2003) in cooperation with the Center for Food Safety and Applied Nutrition (CFSAN) of the Food and Drug Administration (FDA). The workshop featured presentations by 22 experts and was attended by 65 individuals. The agenda can be found in the supplementary data at www.toxsci.oupjournals.org.

Classification and grading of gastritis. The updated Sydney System. International Workshop on the Histopathology of Gastritis, Houston 1994.

The Sydney System for the classification of gastritis emphasized the importance of combining topographical, morphological, and etiological information into a schema that would help to generate reproducible and clinically useful diagnoses. To reappraise the Sydney System 4 years after its introduction, a group of gastrointestinal pathologists from various parts of the world met in Houston, Texas, in September 1994. The aims of the workshop were (a) to establish an agreed terminology of gastritis; (b) to identify, define, and attempt to resolve some of the problems associated with the Sydney System. This article introduces the Sydney System as it was revised at the Houston Gastritis Workshop and represents the consensus of the participants. Overall, the principles and grading of the Sydney System were only slightly modified, the grading being aided by the provision of a visual analogue scale. The terminology of the final classification has been improved to emphasize the distinction between the atrophic and nonatrophic stomach; the names used for each entity were selected because they are generally acceptable to both pathologists and gastroenterologists. In addition to the main categories and atrophic and nonatrophic gastritis, the special or distinctive forms are described and their respective diagnostic criteria are provided. The article includes practical guidelines for optimal biopsy sampling of the stomach, for the use of the visual analogue scales for grading the histopathologic features, and for the formulation of a comprehensive standardized diagnosis. A glossary of gastritis-related terms as used in this article is provided.

Report from the society for biological therapy and vascular biology faculty of the NCI workshop on angiogenesis monitoring.

The field of tumor angiogenesis has seen explosive growth over the last 5 years. Preclinical as well as early clinical evaluation of novel compounds is progressing at a rapid pace. To gain a perspective on the field and to take stock of advances in the understanding of molecular mechanisms underlying the process of tumor angiogenesis as well as ways of monitoring the activity of agents, the Society for Biologic Therapy and the National Cancer Institute's Vascular Biology Faculty convened a Workshop on Angiogenesis Monitoring in November 2002. The Workshop was composed of invited speakers and participants from academia, industry, and government. It was divided into 3 sessions, each chaired by leaders in the field. The first focused on advances in the understanding of the cellular and molecular mechanisms of angiogenesis in tumors. The second examined preclinical assay systems that are useful in vascular biology. The third addressed the translation to the clinic and monitoring of antiangiogenic activity of agents in patients and novel trial designs. What follows is a summary of the discussions and findings of each session.

Exposure guidelines for low-frequency electric and magnetic fields: report from the Brussels workshop.

The EMF Exposure Guidelines Science Workshop was held to evaluate the information base for guidelines for electric and magnetic field exposures at extremely low frequencies, to identify research needs, and to discuss how best to apply scientific knowledge in developing exposure recommendations. Although the existing guideline values are based on electrostimulation of nerve and muscle tissues, guidelines must also consider controversial studies of potential health effects from chronic exposures at environmental levels that are far too weak to cause electrostimulation. The size of the safety factor applied in specifying exposure limits reflects a variety of factors that introduce uncertainties. These include confidence in existing dose-effect relationships, population diversity, the reliability and precision of techniques to control over-exposure, and completeness of the information base, particularly regarding long-term effects. Specific research questions that can change the level of uncertainty meaningfully were identified in these areas: biophysical mechanisms of electrostimulation; the range of thresholds throughout exposed populations; cancer causation in children and adults, including a possible role for contact currents; cognitive, behavioral, and physiological effects on the central nervous system; improved dosimetry; and better understanding of electromagnetic interference with implanted biomedical devices such as pacemakers, defibrillators, and physiological monitors. This report introduces ten papers from the workshop that address these and related topics in detail.
