Biomedical informatics methods in pharmacogenomics.

Pharmacogenomics is the study of the genetic basis of individual variation in response to therapeutic agents. Pharmacogenomics may potentially affect on every step of health care and every drug treatment protocol. The optimal approach to pharmacogenomics in hypertension requires the integration of different disciplines, in which biomedical informatics plays an essential role. This chapter describes biomedical informatics methods used in dealing with key issues in pharmacogenomics. These key issues include the association between structure and function, the interaction between gene and drug, and the correlation between genotype and phenotype. Heterogeneous resources, including web sites, databases, and software analysis tools, are selected, organized, and integrated in practical methods to support these studies. Bioinformatics methods described in this chapter include genetic sequence searching, comparison, structural modeling, functional analysis, and systems biology studies, with emphasis on single-nucleotide polymorphism (SNP) analysis. Medical informatics methods such as disease and drug information and clinical terminology are also embraced in this chapter. This combination of both biological and medical informatics provides comprehensive methodologies to resolve complex problems in pharmacogenomics.

Prediction of human microRNA targets.

MicroRNAs (miRNAs) are small, nonprotein-coding RNAs that regulate gene expression. Although hundreds of human miRNA genes have been discovered, the functions of most of these are unknown. Computational predictions indicate that miRNAs, which account for at least 1% of human protein-coding genes, regulate protein production for thousands of or possibly all of human genes. We discuss the functions of mammalian miRNAs and the experimental and computational methods used to detect and predict human miRNA target genes. Anticipating their impact on genome-wide discovery of miRNA targets, we describe the various computational tools and web-based resources available to predict miRNA targets.

Development and dissemination of potentially better practices for the provision of family-centered care in neonatology: the family-centered care map.

OBJECTIVE: Family-centered care has become integral to the provision of quality neonatal intensive care. However, practices that reflect the core principles of family-centered care have not been described fully in the literature or implemented and evaluated consistently within newborn intensive care. The objective of this study was to create a family-centered care map that enhances the ability of the health care team to work with families to coordinate and deliver care in a holistic manner to meet the developmental, physical, and psychosocial needs of NICU patients and their families. METHODS: Potentially better practices were developed for sequential clinical phases by using standardized methods. These included focus groups with families, brainstorming sessions with staff, literature review, and input from established family advisory groups and family-centered care experts. Potentially better practices then were integrated into the family-centered care map that was configured in a Web-based format. Overall utility will be evaluated by determining the effect of the family-centered care map on length of stay, parental satisfaction, and family-centered care beliefs and practices among NICU staff. RESULTS: Sixty-three potentially better practices were identified for 7 clinical phases and 3 variations that were believed to characterize the clinical course of a typical NICU patient. A prototype of the Web-based family-centered care map that illustrates the clinical phases with links to the related potentially better practices, operational processes, and case studies was created. Baseline data from a care provider survey, from a family satisfaction survey, and on length of stay have been collected. CONCLUSIONS: Quality improvement methods and collaboration among 3 centers led to the development of an innovative Web-based resource to assist individual care providers and family advisors to provide comprehensive family-centered care to infants and families. Implementation of the family-centered care map has potential to affect positively the quality of newborn intensive care and lead to improved long-term outcomes.

Factors related to in-house agricultural animal caseloads in US veterinary teaching hospitals.

A retrospective observational study was conducted to determine whether agricultural animal caseloads at veterinary teaching hospitals declined between 1995 and 1998. Thereafter, the effect of organizational and demographic factors on 1998 in-house agricultural animal caseloads was examined. Caseload data were obtained from the American Association of Veterinary Medical Colleges. Demographic and organizational data were obtained by surveys, telephone interviews, and web-based resources. Complete data were available from 25 veterinary colleges, and data from these schools were used in subsequent analyses. In 1998, in-house food animal caseload decreased relative to 1995 in 17 schools and increased relative to 1995 in 8 schools. This trend was not significant (P = .053); however, the power of the test was limited (.50). Mean 1998 caseload was 886 +/- 504. Among schools with a discipline-based organizational structure, annual mean caseload was 464 +/- 220. Among schools with a species-based organizational structure, mean caseload was 1,167 +/- 463. The regression model that best predicted caseload was a forward-stepping model that included only organizational structure as an independent variable. No additional independent variable was significantly associated with caseload.

Using the internet to enhance physician-patient communication.

The rise in Internet use by patients with musculoskeletal problems has put orthopaedic surgeons under increased pressure to provide Web-based resources. Patients are researching musculoskeletal conditions online, and many want to communicate electronically with their physicians. Online medical information may be a useful adjunct to traditional physician-patient interaction because it is readily available, is wide in scope, and can provide the patient with basic knowledge on a given topic. A clinical encounter may then be efficiently spent refining information and answering specific questions. Orthopaedic surgeons should be aware of the advantages of using Internet resources as part of their practice as well as the potential legal and confidentiality pitfalls in electronic communication. Some patient concerns may be easily satisfied and communication enhanced through the use of e-mail. Physicians planning to incorporate electronic communication with their patients must be prepared to manage unsolicited e-mail, maintain patient confidentiality, and adopt practices that maximize the use of online resources to enhance patient education.

Analysis of palliative care content in nursing textbooks.

Overall, this study demonstrates significant deficiencies in end-of-life care content in nursing textbooks. Defining palliative care, quality of life at the end of life, and issues of policy, ethics, and law are the foundation of end-of-life care. Analysis of these topics revealed a need to clarify concepts and to apply them within the context of end-of-life care. The analysis also demonstrated a need to transfer findings from palliative care research and concepts from hospice into basic education. In March 1999 the investigators convened a conference in New York in collaboration with a group of medical investigators analyzing EOL content in medical textbooks. The conference was also attended by publishers, editors, and authors of textbooks. The investigators were very encouraged by their interest in and commitment to correcting any weaknesses in their books. The investigators provided them with specific recommendations for improvement and resources for locating both appropriate content and authors with palliative care expertise. These resources are also made available on the City of Hope Pain Resource Center Web site (http:@mayday.coh.org). Achieving the overall project goal of strengthened nursing education in end-of-life care will be reached through a variety of measures. Improving textbooks is but one important step. The various disciplines involved in palliative care can contribute to this project by working in collaboration with textbook publishers.

The effectiveness and cost-effectiveness of prophylactic removal of wisdom teeth.

BACKGROUND: Removal of wisdom teeth is one of the most common surgical procedures performed in the UK. Little controversy surrounds the removal of impacted third molars when they are associated with pathological changes such as infection, non-restorable carious lesions, cysts, tumours, and destruction of adjacent teeth and bone. However, the justification for prophylactic removal of impacted third molars is less certain and has been debated for many years. OBJECTIVES: To provide a summary of existing evidence on prophylactic removal of impacted wisdom teeth, in terms of the incidence of surgical complications associated with prophylactic removal, and the morbidity associated with retention. METHODS: A systematic review of the research literature was undertaken. METHODS - DATA SOURCES: An existing review formed the basis of this report, and additional literature searches were undertaken, including searches of electronic databases (MEDLINE, 1984-99; EMBASE, 1984-99; Science Citation Index, Cochrane Controlled Trials Register, National Research Register; Database of Abstracts of Reviews of Effectiveness), paper sources (including Clinical Evidence), and web-based resources. Relevant organisations and professional bodies were contacted for further information. METHODS - STUDY SELECTION: Studies were selected for inclusion if they met the following criteria: (1) design - randomised controlled trials (RCTs), literature reviews, or decision analyses; (2) participants - people with unerupted or impacted third molars, or those undergoing surgical removal of third molars either as prophylaxis or due to associated pathological changes; (3) reported outcomes - either the pathological changes associated with retention of third molars, or post-operative complications following extraction. There were no language restrictions on study selection. METHODS - DATA EXTRACTION AND SYNTHESIS: Data from included studies were extracted into structured tables and individual study validity was assessed against methodological checklists. Data were summarised descriptively. Decisions relating to study selection, data extraction and validity assessment were made by two independent reviewers, and disagreements were resolved by discussion. For non-English papers, translators were recruited to assist with study selection and data extraction. RESULTS: Forty studies were included in the review: two RCTs, 34 literature reviews, and four decision analysis studies. One RCT in the UK focused on the effects of retained third molars on incisor crowding (predominantly a cosmetic problem) in patients who had previously undergone orthodontic treatment. The results of this trial suggested that the removal of third molars to prevent late incisor crowding cannot be justified. Another on-going RCT in Denmark compares the effects and costs of prophylactic removal of third molars with removal according to morbidity. So far, this trial has recruited 200 participants, and preliminary results indicate that watchful waiting may be a promising strategy. However, more data and longer follow-up of patients are needed to conclude which treatment strategy is the most cost-effective. It is also known that a trial is on-going in the USA but no results are available so far. The methodological quality of the literature reviews was generally poor, and none of the reviews was systematic. Conclusions from nine reviews on anterior crowding suggested that there was only a weak association between retention of third molars and crowding. Six out of 21 reviews with a more general scope also concluded that the prophylactic removal of third molars was unjustified. Twelve general reviews did not conclude with a clear message about the management of third molars. Three reviews suggested that prophylactic removal of third molars is appropriate, but these reviews were of poorer methodological quality than the majority of other reviews. Three out of four papers focusing on surgical management expressed

A new program to reward and retain volunteer clinical faculty at the Medical College of Wisconsin.

UNLABELLED: BACKGROUND AND PROBLEM: Volunteer clinical faculty (VCF) are vital to the educational mission of medical schools. At the Medical College of Wisconsin (MCW), VCF are increasingly relied upon to meet clinical training needs in medical student and resident education. However, many VCF receive little or no preparation to excel in their teaching roles, and they are under increasing time demands that limit their availability to teach. METHODS: Beginning in 2001, the primary care departments at MCW began a series of initiatives called "ExCEED" to promote VCF teaching excellence and efficiency through two main program components: Advisory Councils, made up of VCF leaders, and Support Services, such as web-based resources and teaching workshops. RESULTS: Preliminary ExCEED findings show that VCF have acquired important knowledge, skills, and tools that have better prepared them for their teaching roles. CONCLUSION: ExCEED is a systematic, multi-method approach to engage VCF that is positively influencing the clinical education of MCW students and residents.

Smoking cessation: what works in primary care settings.

This paper presents evidence-based strategies for assisting patients in quitting smoking. Summaries of the effectiveness of advice alone, varying levels of behavioral counseling, nicotine replacement therapies, and bupropion either alone or in combinations are presented. We describe two web-based resources, one that offers guidance to practitioners and another that is intended as a training tool for students or healthcare professionals on ways to intervene with patients who smoke. The training curriculum contains both didactic material based on the U.S. Public Health Service Clinical Practice Guideline and tutorials with simulated patients depicting various types of real-life scenarios. The curriculum can meet the need for training among both students and practitioners in medicine, nursing, health education, dentistry, and other healthcare professions.

An innovative approach to enhancing the surveillance capacity of state-based diabetes prevention and control programs: the Diabetes Indicators and Data Sources Internet Tool (DIDIT).

The Diabetes Indicators and Data Sources Internet Tool (DIDIT) is an interactive Web-based resource with information on 38 diabetes indicators (e.g., diabetes-associated complications, care, lifestyle) and 12 associated data sources frequently used by state diabetes prevention and control programs. This tool is designed to strengthen the ability of states to conduct diabetes surveillance and to promote consistency in defining and tracking indicators across states. In this way, the DIDIT supports one of the 10 essential public health services: the timely and accurate assessment of public health. In addition to serving as a central repository of information on diabetes surveillance, the DIDIT also allows users to share experiences of using these indicators and data sources in their diabetes surveillance activities, data analysis, and tracking of diabetes-related objectives stated by Healthy People 2010. The DIDIT is an innovative approach to enhancing public health surveillance at the state and national levels.

Ukraine and Russia: major InterNICHE outreach.

During October 2005, InterNICHE National Contacts Anya Yushchenko and Lena Maroueva, and Co-ordinator Nick Jukes, began a large-scale promotion of alternatives across the Ukraine and Russia. The InterNICHE outreach produced a number of positive results: presentations, demonstrations and training in alternatives to over 500 teachers and students; agreements at two institutes to replace harmful animal use in education across a whole department and faculty respectively; information gathering, and discussions with teachers about potential future replacement; reaching a massive audience through positive media coverage; and empowerment of campaigners, including InterNICHE National Contacts who successfully organised the majority of the activities. To continue the successes, funds to enlarge the Russian micro-Loan System of alternatives and to make donations of alternatives to institutes are urgently needed. Support for broadening the InterNICHE impact across Ukraine, Russia and Asian republics through the distribution of translated literature, video, freeware alternatives and web-based resources is also required. Such activity not only supports the development of a progressive, humane education, but impacts positively on animal use in research and testing by creating an environment more conducive to alternatives in general. This is important now as animal testing laboratories consider relocating in or sub-contracting to ex-Soviet countries and in central Asia. New InterNICHE connections have already been made with Belarus, Armenia, Azerbaijan and Kyrgyzstan, and there are many open doors.
