Publicly-funded biobanks and networks in East Asia

Support for Research Biobanks Among Medical Students in the Republic of Kazakhstan

Background: Over the past few years, several biobanks have been organized in the Republic of Kazakhstan (RoK). As research biobanks are becoming an increasingly important tool for precision medicine, they require competent biobankers who will help disseminate the idea of biobanking throughout the society and support donation for research purposes. This study aimed to assess the support for research biobanks among medical students (MSs) in Kazakhstan. Methods: This research includes data from an anonymous, self-administered online questionnaire regarding MSs' support for research biobanks in the RoK. Results: Only 212 (31.3%) MSs have heard of biobanks and 466 (68.7%) have not. Students who were biobank-aware held more positive views regarding biobanks, were more likely to support the idea of establishing a research biobank in Kazakhstan, and expressed a greater willingness to donate their biological material for research purposes. Students' awareness of biobanks was also associated with the respondents' motivations to donate. Students who were familiar with biobanks tended to be motivated by altruistic reasons more often, and those unfamiliar with biobanks tended to indicate selfish motives. Students' attitudes toward donation to various types of research and biobanks were influenced by their awareness of biobanks, any family history of genetic disease, experience of chronic disease, declared religiousness, hospitalization history, blood donor status, and year of study. Conclusion: Since MSs' awareness of research biobanks is low, there is an urgent need for biobank education in Kazakhstan.

Increasing diversity of functional genetics studies to advance biological discovery and human health

In this perspective we discuss the current lack of genetic and environmental diversity in functional genomics datasets. There is a well-described Eurocentric bias in genetic and functional genomic research that has a clear impact on the benefit this research can bring to underrepresented populations. Current research focused on genetic variant-to-function experiments aims to identify molecular QTLs, but the lack of data from genetically diverse individuals has limited analyses to mostly populations of European ancestry. Although some efforts have been established to increase diversity in functional genomic studies, much remains to be done to consistently generate data for underrepresented populations from now on. We discuss the major barriers for this continuity and suggest actionable insights, aiming to empower research and researchers from underserved populations.

Improving Public Trust in Biobanking: Roundtable Discussions from the 2021 ISBER Annual Meeting

Biobanking is a relatively newly recognized and innovative branch of science, which includes the collection of samples and associated data from hospitals, diagnostic centers, and voluntary donations for biomedical and environmental research. It involves diverse stakeholders at the junction of society, science, ethics, law, and politics. A key element in the success of a biobank is the trust and support of public donors, clinicians, and scientists. To achieve trust, it is important to implement strategies that can increase biobank awareness in common people, and different types of communities. Biobank laws and regulations and transparent governance by the biobanks are also crucial to achieving public trust.

Challenges on the Development of Biodiversity Biobanks: The Living Archives of Biodiversity

Biodiversity biobanks or ex situ biodiversity biorepositories tend to receive less attention compared with their biomedical counterparts. In this review, we highlight the necessity for these biorepositories by presenting their significant role in health, biodiversity, linking of big data, other translational research, and biodiversity conservation efforts. Moreover, the significant challenges in developing and maintaining biodiversity biobanks based on successful biobanks in some megadiverse developing countries are examined to provide insights into what needs to be done and what can be improved by up-and-coming biodiversity biobanks. These challenges include lack of financial support and political will; availability of experts; development of standard policies; and information management system. In addition, issues regarding access and benefit sharing and Digital Sequence Information must be addressed by biodiversity biobanks.

An overview of cord blood stem cell transplantation in Hong Kong

Haematopoietic stem cell graft derived from cord blood is standard therapy for several haematological malignancies and other diseases. The study reports cases of public and private (family) cord blood biobanking services and the related hematopoietic stem cell transplantation ever performed in Hong Kong. The published original research papers and review articles from inception to Nov 2022 have been searched for on Pubmed, Microsoft Academic Search, and Google Scholar to identify reports on existing or terminated cord blood biobanking and transplantation service in Hong Kong. Moreover, all data publicly available on the official websites of the local cord blood banks and local mainstream media has been analysed. The public Hong Kong Red Cross Blood Transfusion Service delivers the highest quantity of haematopoietic stem cell transplants. Among the private sector, HealthBaby releases the most cord blood units for clinical use in diseases in both autologous and allogeneic administration, followed by Cordlife HK.  Both public and private (family) cord blood biobanks have been and continue to contribute to the Hong Kong cord blood donor registry. However, the growth of the cord blood inventory is detrimental to donor-recipient matching for lifesaving therapy.

Breast Cancer in Asia: Incidence, Mortality, Early Detection, Mammography Programs, and Risk-Based Screening Initiatives

Simple Summary

Nearly all breast cancer patients survive for more than five years when the tumor is found early and in the localized stage. Regular clinical breast examinations, mammograms, and monthly self-exams of the breasts all contribute to early detection. However, late-stage breast cancers are common in many Asian countries. Low-income countries suffer from a lack of resources for breast cancer screening. High-income countries, on the other hand, are not benefiting fully from national breast screening programs due to an underutilization of the preventive healthcare services available. Existing reviews on Asian breast cancers are heavily focused on risk factors. The question of whether we should adopt or adapt the knowledge generated from non-Asian breast cancers would benefit from an extension into screening guidelines. In addition, several Asian countries are piloting studies that move away from the age-based screening paradigm.

Abstract

Close to half (45.4%) of the 2.3 million breast cancers (BC) diagnosed in 2020 were from Asia. While the burden of breast cancer has been examined at the level of broad geographic regions, literature on more in-depth coverage of the individual countries and subregions of the Asian continent is lacking. This narrative review examines the breast cancer burden in 47 Asian countries. Breast cancer screening guidelines and risk-based screening initiatives are discussed.

Mini-Review of Laboratory Operations in Biobanking: Building Biobanking Resources for Translational Research

Biobanks have become integral to improving population health. We are in a new era in medicine as patients, health professionals, and researchers increasingly collaborate to gain new knowledge and explore new paradigms for diagnosing and treating disease. Many large-scale biobanking efforts are underway worldwide at the institutional, national, and even international level. When linked with subject data from questionnaires and medical records, biobanks serve as valuable resources in translational research. A biobank must have high quality samples that meet researcher's needs. Biobank laboratory operations require an enormous amount of support—from lab and storage space, information technology expertise, and a laboratory management information system to logistics for sample movement, quality management systems, and appropriate facilities. A paramount metric of success for a biobank is the concept of every biospecimen coming to the repository belongs to a participant who has something to contribute to research for a healthier future. This article will discuss the importance of biorepository operations, specific to the collection and storage of participants materials. Specific focus will be given to maintaining the quality of samples, along with the various levels of support biorepositories need to fulfill their purpose and ensure the integrity of each specimen is maintained.

Bioprospecting for Antibacterial Drugs: a Multidisciplinary Perspective on Natural Product Source Material, Bioassay Selection and Avoidable Pitfalls

Bioprospecting is the exploration, extraction and screening of biological material and sometimes indigenous knowledge to discover and develop new drugs and other products. Most antibiotics in current clinical use (eg. β-lactams, aminoglycosides, tetracyclines, macrolides) were discovered using this approach, and there are strong arguments to reprioritize bioprospecting over other strategies in the search for new antibacterial drugs. Academic institutions should be well positioned to lead the early stages of these efforts given their many thousands of locations globally and because they are not constrained by the same commercial considerations as industry. University groups can lack the full complement of knowledge and skills needed though (eg. how to tailor screening strategy to biological source material). In this article, we review three key aspects of the bioprospecting literature (source material and in vitro antibacterial and toxicity testing) and present an integrated multidisciplinary perspective on (a) source material selection, (b) legal, taxonomic and other issues related to source material, (c) cultivation methods, (d) bioassay selection, (e) technical standards available, (f) extract/compound dissolution, (g) use of minimum inhibitory concentration and selectivity index values to identify progressible extracts and compounds, and (h) avoidable pitfalls. The review closes with recommendations for future study design and information on subsequent steps in the bioprospecting process.

A Pilot Cancer-Phenome Biobanking System in a Low-Resource Southeast Asian Setting: The Philippine General Hospital Biobank Experience

Biobanking has become an indispensable tool for translational research and health innovations. While the field of biobanking has progressed and evolved globally, biobanking in developing Association of Southeast Asian Nations (ASEAN) countries such as the Philippines remains underrepresented because of several challenges often encountered in these low- and middle-income countries. Recently, the Philippine government has undertaken enormous efforts to advancing research and development in the country, and one of the current research pursuits is the establishment of biobanks, with the hope of attaining more discoveries and innovations in the future. Given that cancer remains a leading cause of death in the Philippines, the Philippine government supported the establishment of a cancer biobank at the Philippine General Hospital (PGH). In this study, we present a specific use case of biobanking activity at the PGH Biobank, to build a cohort of biospecimens from Filipino patients with breast, endometrial, and ovarian cancer. This initiative is part of a biomonitoring study (1) to assess environmental exposures and possible risk factors in the Philippine population and (2) to develop a system of culturing human cells from Filipino patients for subsequent in vitro studies. We discuss issues faced and the solutions developed during the implementation of the biobank. Strong research collaboration, a funding source, basic infrastructure, and appropriate technology helped initiate this pilot biobank in the Philippines. Overall, the experiences of establishing the PGH Biobank may help other institutions in low-resource countries to set up cancer biobanks.

Preservation, Characterization and Exploitation of Microbial Biodiversity: The Perspective of the Italian Network of Culture Collections

Microorganisms represent most of the biodiversity of living organisms in every ecological habitat. They have profound effects on the functioning of any ecosystem, and therefore on the health of our planet and of human beings. Moreover, microorganisms are the main protagonists in food, medical and biotech industries, and have several environmental applications. Accordingly, the characterization and preservation of microbial biodiversity are essential not only for the maintenance of natural ecosystems but also for research purposes and biotechnological exploitation. In this context, culture collections (CCs) and microbial biological resource centres (mBRCs) are crucial for the safeguarding and circulation of biological resources, as well as for the progress of life sciences. This review deals with the expertise and services of CCs, in particular concerning preservation and characterization of microbial resources, by pointing to the advanced approaches applied to investigate a huge reservoir of microorganisms. Data sharing and web services as well as the tight interconnection between CCs and the biotechnological industry are highlighted. In addition, guidelines and regulations related to quality management systems (QMSs), biosafety and biosecurity issues are discussed according to the perspectives of CCs and mBRCs.
