The gut microbiome (GM), a complex community of bacteria, viruses, protozoa, and fungi located in the gut of humans and animals, plays significant roles in host health and disease. Animal models are widely used to investigate human diseases in biomedical research and the GM within animal models can change due to the impact of many factors, such as the vendor, husbandry, and environment. Notably, variations in GM can contribute to differences in disease model phenotypes, which can result in poor reproducibility in biomedical research. Variation in the gut microbiome can also impact the translatability of animal models. For example, standard lab mice have different pathogen exposure experiences when compared to wild or pet store mice. As humans have antigen experiences that are more similar to the latter, the use of lab mice with more simplified microbiomes may not yield optimally translatable data. Additionally, the literature describes many methods to manipulate the GM and differences between these methods can also result in differing interpretations of outcomes measures. In this review, we focus on the GM as a potential contributor to the poor reproducibility and translatability of mouse models of disease. First, we summarize the important role of GM in host disease and health through different gut–organ axes and the close association between GM and disease susceptibility through colonization resistance, immune response, and metabolic pathways. Then, we focus on the variation in the microbiome in mouse models of disease and address how this variation can potentially impact disease phenotypes and subsequently influence research reproducibility and translatability. We also discuss the variations between genetic substrains as potential factors that cause poor reproducibility via their effects on the microbiome. In addition, we discuss the utility of complex microbiomes in prospective studies and how manipulation of the GM through differing transfer methods can impact model phenotypes. Lastly, we emphasize the need to explore appropriate methods of GM characterization and manipulation.

Cervical dislocation is a commonly used method of mouse euthanasia. Euthanasia by isoflurane inhalation is an alternative method which allows the sacrifice of several mice at the same time with an anaesthesia, in the aim to decrease pain and animal distress. The objective of our study was to assess the impact of these two methods of euthanasia on the quality of mouse oocytes. By administering gonadotropins, we induced a superovulation in CD1 female mice. Mice were randomly assigned to euthanasia with cervical dislocation and isoflurane inhalation. Oviducts were collected and excised to retrieve metaphase II oocytes. After microscopic examination, oocytes were classified into three groups: intact, fragmented/cleaved and atretic. Intact metaphase II oocytes were employed for biomedical research. A total of 1442 oocytes in the cervical dislocation group were compared with 1230 oocytes in the isoflurane group. In the cervical dislocation group, 93.1% of the oocytes were intact, versus 65.8% in the isoflurane group ( P ≤ 0.001). In light of these results, we conclude that cervical dislocation is the best method of mouse euthanasia for obtaining intact oocytes for biomedical research.

Background: Impact in research encompasses health, economic, and cultural benefits beyond adding to the knowledge base. Funders are under immense pressure to be accountable for the paybacks from funded research.Aims and objectives: The aim of this study was to look into the impact of funded biomedical research between the years 2005 and 2015 in Malaysia from the aspects of knowledge production, research targeting and capacity building, as well as health system policy and decision making.Methods: This study employed a convergent parallel mixed-methods research design. Biomedical projects related to breast cancer, coronary heart disease, and dengue, funded by the Ministry of Health (MOH), Ministry of Higher Education (MOHE), and Ministry of Science, Technology, and Innovation (MOSTI) between the years 2005 and 2015, were included.Findings: From the questionnaire responses (n=58), on average each funded project managed to produce two outputs and one higher degree student. More than half (61.4%) of the funded projects led to subsequent future research. However, low citations in systematic reviews (10.3%), health policies (6.9%), and clinical practice guidelines (5.2%) were reported. In-depth interviews with the key opinion leaders also saw that most of the local research findings were found to be irrelevant to be adopted into policies by the policymakers.Discussion and conclusions: Paybacks on knowledge production as well as research targeting and capacity building had been achieved, but impact on health system policy and decision making had not been well attained, due to the lack of relevant research findings needed by the policymakers.<br />Key messages<br /><ul><li>Payback on knowledge production was achieved, as there had been a lot of new knowledge generated as captured in academic publications, conference proceedings, policy briefs, technical reports, and research highlights, which is important to advance the frontiers of knowledge.</li><br /><li>Payback on research targeting was achieved, with the current research leading to future study with identification of the knowledge gap and generation of new ideas for new research.</li><br /><li>Payback on capacity building was achieved with the training of researchers, building up research capacity and competencies, production of MSc and PhD graduates, promotion of lecturers, and development of new partnerships and networks.</li><br /><li>Impact on health system policy and decision making was not well attained. There had been a lack of relevant research data and findings being incorporated into policymaking, due to the basic and fundamental nature of most of the funded biomedical research in Malaysia.</li></ul>

In the decades since its independence in 1965, the transformation of Singapore’s economy and its transition to a relatively developed economy has also in like manner transformed its health care system, and of the demands made of it. The emergence and availability of new medical technologies has put into sharp focus many novel legal, ethical as well as social issues. This chapter looks at how Singapore has attempted to respond to issues thrown up by genetic testing and screening technologies. A particular focus of this chapter will be the tension between privacy concerns, and the imperatives of access for biomedical research, given that biomedical research has been championed by the Singapore government as one of the future leading sectors of the economy of Singapore. This chapter also examines Singapore’s approach to the question of “genetic exceptionalism:” Does genetic information possess special qualities or attributes that remove it from the realm of ordinary personal information, and which thereby demands special treatment and protection? In this context, the impact of the doctrine of genetic exceptionalism on industry (in this case the insurance industry) is examined.

ObjectivesTo design, deliver and evaluate a programme of training workshops for biomedical researchers aimed at building confidence and skills in actively involving patients and the public (PPI) in research.DesignA bespoke programme of training workshops in PPI aimed at researchers.SettingA large National Institute for Health Research Biomedical Research Centre in London and several partner organisations.Participants721 scientists, clinicians and research managers attending dedicated training in PPI at a major London NHS (National Health Service)–university partnership.InterventionsA programme of 72 training workshops, designed to build practical skills and confidence for researchers working with patients and the public in research, was delivered at a major research-active NHS:university partnership. An iterative approach was taken to the programme, with the content of the workshops continually reviewed and refreshed to respond to the needs of researchers. Surveys before, immediately following and 6 months after training investigated the impact on researchers’ confidence and skills in PPI work, and the kind of PPI they subsequently carried out.ResultsTraining brought about immediate marked increases in researchers’ self-reported confidence to carry out PPI activities within their research, and in their knowledge of good practice. The evaluation indicates that workshop attendees were more likely to involve patients in their research following training. Researchers tended to involve patients and the public in a range of areas, including input to study design and patient information, in particular.ConclusionsWhen positioned within a broader organisational strategy for PPI in research, such training has an important role to play in progressing PPI in a major research partnership. Training appeared to provide the confidence needed to carry out PPI which enabled further development of confidence and skills. Involving researchers who have attended the training in the ongoing development of the programme and bringing in patients to the training programme are key next steps.

Idaho Institutional Development Award (IDeA) Network for Biomedical Research Excellence (INBRE) aims to build biomedical research capacity and enhance the scientific and technology knowledge of the Idaho workforce. A key INBRE Program at The College of Idaho, a primarily undergraduate institution of 1,100 students, is a 10-wk summer fellows research experience. This report documents outcomes from 2005 to present, including demographic trends, faculty and student research productivity, self-reported gains, educational attainment, and career outcomes. Of 103 participants, 83.7% were from Idaho, 26.7% from rural areas, and 23.9% first-generation college students. Faculty and student research productivity (conference presentations and peer-reviewed publications) increased threefold. We found that 91.4% of fellows entered a scientific- or healthcare-related career and that 70.7% completed or are currently enrolled in postgraduate training (51.7% doctoral and 19.0% master’s level). Anonymous surveys were uniformly positive, with gains in self-confidence and independent laboratory work. Open-ended responses indicated students valued mentoring efforts and improved awareness of scientific opportunities and competitive preparation for postgraduate training. Lastly, we observed that student research involvement increased college-wide during the award period. These data suggest that the summer fellows program is successfully meeting National Institutes of Health IDeA goals and serving as a pipeline to future health research careers and a scientifically trained Idaho workforce.
