Karamanoglu I, Nielsen DE. Healthcare Professional Clinical Actions following Nutrigenomics Testing in Practice. Public Health Genomics 2020; 23:237-245.

Abstract
<b><i>Background:</i></b> Clinical demand for nutrigenomics testing (NGT) is increasing, underscoring the importance of assessing healthcare professional (HCP) competence and clinical actions with NGT in practice. While previous studies have explored HCP perceptions of NGT, no study has examined real HCP experiences with NGT in practice. <b><i>Objective:</i></b> The objective of this study was to evaluate the clinical experience of providing NGT among early adopter HCPs who have used NGT in their practice. We hypothesized that HCP clinical actions after NGT would differ according to HCP personal experience undergoing genetic testing (GT) as well as years in practice. <b><i>Design:</i></b> An online survey questionnaire was administered to HCPs (<i>n</i> = 70) who have provided NGT in practice. χ<sup>2</sup> tests, tests for trend, and logistic regression were used to compare HCP characteristics with post-NGT outcomes. <b><i>Results:</i></b> HCPs with fewest years in practice (<5 years) comprised the lowest proportion of respondents (16%). Most HCPs reported good understanding of NGT results and 92% made genetic-based dietary recommendations to patients following NGT. HCP personal use of GT increased significantly with increasing years in practice (<5 years: 36%, 5–10 years: 53%, 11–20 years: 70%, and >20 years: 85%, <i>p</i> trend = 0.003). Requesting patient bloodwork because of NGT results increased significantly with HCP years in practice when HCPs with <5 years in practice were not considered (5–10 years: 19%, 11–20 years: 28%, and >20 years: 60%, <i>p</i> trend = 0.010). A near significant difference was observed where a greater proportion of HCPs who had personally undergone GT reported requesting patient bloodwork (personal use: 46% vs. no personal use: 23%, <i>p</i>-χ<sup>2</sup> = 0.066). <b><i>Conclusion:</i></b> Early HCP adopters of NGT utilize the test results to provide genetic-based dietary recommendations to patients. Clinical action after NGT currently appears to be driven by HCP years in practice, but HCP personal use of GT may also be a factor.

Abstract
Individualized nutrition counseling and care is a cornerstone of practice for registered dietitian nutritionists (RDNs). The term personalized nutrition (PN) refers to "individual-specific information founded in evidence-based science to promote dietary behavior change that may result in measurable health benefits." PN technologies, which include the "omics" approaches, may offer the potential to improve specificity of nutrition care through assessment of molecular-level data, such as genes or the microbiome, in order to determine the course for nutrition intervention. These technologies are evolving rapidly, and for many RDNs, it is unclear whether, when, or how these technologies should be incorporated into the nutrition care process. In order to provide guidance in these developing PN fields, International Life Sciences Institute North America convened a multidisciplinary panel to develop guiding principles for PN approaches. The objective of this article is to inform RDN practice decisions related to the implementation of PN technologies by examining the alignment of proposed PN guiding principles with the Code of Ethics for the Nutrition and Dietetics Profession, as well as Scope and Standards of Practice. Guiding principles are described as they apply to each stage of the nutrition care process and include identifying potential beneficiaries, communicating effects transparently, and protecting individual privacy. Guiding principles for PN augment standard guidance for RDNs to pose relevant questions, raise potential concerns, and guide evaluation of supporting evidence for specific PN technologies. RDNs have a responsibility to think critically about the application of PN technologies, including appropriateness and potential effectiveness, for the individual served.

"Omics" Education in Dietetic Curricula: A Comparison between Two Institutions in the USA and Mexico. Lifestyle Genom 2019; 11:136-146. [PMID: 31067544 DOI: 10.1159/000499202] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Accepted: 02/26/2019] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND/AIMS The completion of sequencing of the human genome and a better understanding of epigenomic regulation of gene expression have opened the possibility of personalized nutrition in the near future. This has also created an immediate need for trained personnel qualified to administer personalized nutrition education. Of all the allied healthcare personnel, dietitians are the most likely to undertake this role. However, dietitians and dietetic students are still deficient in their knowledge of nutrigenomics and other "omics" technologies. Therefore, with the eventual goal of dietetic curriculum reorganization, the International Society of Nutrigenetics/Nutrigenomics (ISNN) has set out to evaluate nutrigenomic knowledge among dietetic students from different countries. In this study, we compared nutrition and dietetic students from Texas Woman's University (TWU) and the Universidad Autónoma de Nuevo León (UANL) for their perceived need for, interest in, and knowledge of different topics within nutritional genomics. METHODS Students from both universities were sent an e-mail link to the survey which was located at psychdata.com. One hundred twenty-seven students completed the survey. The survey assessed the students' knowledge of, perceived need for, and interest in different omics technologies, as well as their basic knowledge of basic nutrition and genetic topics. Differences were assessed using the χ2 test for homogeneity and Fisher's exact test. RESULTS Students from TWU and UANL exhibited differences in their knowledge, desire to learn more, and perceived need for omics science in some but not all categories. CONCLUSIONS Undergraduate nutrition students from both the USA and Mexico lack a high level of knowledge in different omics topics but recognize the role that omics will play in their future as dietitians. There were differences between the 2 universities in terms of the desire to learn more about different omics technologies and to take more classes covering different topics with nutritional genomic components. In order to make personalized nutrition a reality, future dietitians will need to become fluent in different omics technologies.
