'It's much more grey than black and white': clinical geneticists' views on the oversight of consumer genomics in Europe

Chinese expert consensus on standard technical specifications for a gut microecomics laboratory (Review)

The intestinal microbiota is a complex ecosystem that not only affects various physiological functions, such as metabolism, inflammation and the immune response, but also has an important effect on the development of tumors and response to treatment. The detection of intestinal flora enables the timely identification of disease-related flora abnormalities, which has significant implications for both disease prevention and treatment. In the field of basic and clinical research targeting gut microbiome, there is a need to recognize and understand the laboratory assays for gut microbiomics. Currently, there is no unified standard for the experimental procedure, quality management and report interpretation of intestinal microbiome assay technology. In order to clarify the process, the Tumor and Microecology Committee of China Anti-Cancer Association and the Tumor and Microecology Committee of Hubei Provincial Immunology Society organized relevant experts to discuss and put forward the standard technical specifications for gut microecomics laboratories, which provides a basis for further in-depth research in the field of intestinal microecomics.

Survey of Professionals of the European Public Health Association (EUPHA) towards Direct-to-Consumer Genetic Testing

BACKGROUND

The increasing availability of Direct-to-Consumer Genetic Tests (DTC-GTs) has great implications for public health (PH) and requires literate healthcare professionals to address the challenges they pose. We designed and conducted a survey to assess the state of knowledge, attitudes and behaviours of PH professionals members of the European Public Health Association (EUPHA) towards DTC-GTs.

METHODS

EUPHA members were invited to participate and fill in the survey. We performed multivariable logistic regression to evaluate associations between selected covariates and knowledge, attitudes and behaviours of healthcare professionals towards DTC-GT.

RESULTS

Three hundred and two professionals completed the survey, 66.9% of whom were not involved in genetics or genomics within their professional activities. Although 74.5% of respondents were aware that DTC-GTs could be purchased on the web, most of them reported a low level of awareness towards DTC-GTs applications and regulatory aspects. The majority did not approve the provision of DTC-GTs without consultation of a healthcare professional (91.4%), were doubtful about the test utility and validity (61%) and did not feel prepared to address citizens' questions (65.6%). Predictors of knowledge on DTC-GT were the involvement in genetics/genomics and receiving training during the studies (P < 0.0001 and P = 0.043). Predictors of attitudes were medical degree and knowledge about DTC-GTs (P = 0.006 and P = 0.027).

CONCLUSIONS

Our results revealed a high level of awareness of DTC-GT web purchasing and a moderate to low level of awareness towards their applications. Despite the overall positive attitudes, PH professionals reported a high need for strengthening regulatory aspects of DTC-GTs provision process.

Direct-to-consumer genetic testing: an updated systematic review of healthcare professionals' knowledge and views, and ethical and legal concerns

Direct-to-consumer genetic testing (DTC-GT) is becoming increasingly widespread. The aim of this research was to systematically review the literature published on healthcare professionals' knowledge and views about DTC-GT, as an update to a 2012 systematic review. The secondary aim was to assess the knowledge and views of healthcare professionals on the ethical and legal issues pertaining to DTC-GT. A systematic search was performed to identify all relevant studies that have been conducted since 2012. Studies fulfilled the inclusion criteria if they were primary research papers conducted on healthcare professionals about their knowledge and views on health-related DTC-GT. PubMed, Embase, CINAHL, PsycINFO and Medline databases were searched from 2012 to May 2021. Title and abstract were screened, and full texts were reviewed by two study authors independently. New papers included were appraised and data were extracted on study characteristics, knowledge and views on DTC-GT, and ethical and legal issues. A narrative synthesis was conducted. Nineteen new papers were included, along with eight papers from the previous review. There was considerable variation in study participants with differing views, awareness levels, and levels of knowledge about DTC-GT. Genetic counsellors and clinical geneticists generally had more concerns, experience, and knowledge regarding DTC-GT. Ten ethical concerns and four legal concerns were identified. Healthcare professionals' knowledge and experience of DTC-GT, including awareness of DTC-GT ethical and legal concerns, have only minimally improved since the previous review. This emphasises the need for further medical learning opportunities to improve the gaps in knowledge amongst healthcare professionals about DTC-GT.
