Biobancos en otorrinolaringología / Biobanks in otolaryngology

Resumen Los biobancos son una innovadora herramienta biotecnológica y un recurso fundamental para el continuo avance en la investigación científica biomédica, y para el advenimiento de la medicina de precisión. Se han desarrollado de forma exponencial durante los últimos 20 años en el mundo, como también a nivel de nuestro país, con la creación de 10 biobancos desde el año 2004. En ellos se almacenan y organizan distintos tipos de muestras biológicas, asociadas a datos epidemiológicos y genéticos de donantes voluntarios. Todos los especímenes almacenados deben ser preservados con estándares de calidad garantizados, a modo de asegurar trazabilidad, integridad y calidad de las muestras. A pesar de que la mantención de un biobanco puede significar altos costos, a fin de cuentas, abaratan costos de los estudios clínicos, dado que es precisamente el biobanco quien se encarga de la obtención de datos y muestras clínicas confiables, permitiendo realizar múltiples estudios a partir de las mismas muestras. A través de este proceso, los biobancos permiten mantener una fuente confiable de recur-sos para la investigación en diversas áreas de la medicina, dentro de ellas la otorrinolaringología. En otorrinolaringología, los biobancos han significado un gran avance, facilitando la investigación en relación con hipoacusia, presbiacusia y tinnitus, así como en el área oncológica. En un futuro, se espera que la comunidad científica haga uso de este recurso, pudiendo expandir su utilidad no solo en el área médica, sino también en otras profesiones de la salud, maximizando así su gigantesco potencial.

Abstract Biobanks are novel biotechnological tools and a fundamental resource for the constant development of biomedical research, as much as for the growing practice of precision medicine. They have proliferated worldwide over the past 20 years and Chile has not been left behind with the creation of 10 bio-banks since 2004. Biobanks store and organize different types of biological samples associated with epidemiological and genetic data from volunteer donors. These samples are stored and preserved under guaranteed quality standards to ensure their traceability, integrity, and quality. Even though the price of maintaining a biobank may seem high, after all, they reduce the costs of research, since biobanks are responsible of the acquisition and storage of data and samples, allowing the performance of multiple studies from the same collection of specimens. In this direction, biobanks grant a constant source of well-founded scientific material for investigation in a wide range of medical fields, such as otolaryngology among them. In otolaryngology, the biobanks have meant a great improvement, facilitating investigations related to deafness, presbycusis, tinnitus and oncology. In the future we hope the scientific community will expand the use this innovative tool over a broader medical field and towards other health-related professions, making the most of its enormous potential.

'We came here to stay': Making biobanks worth maintaining in Spain.

The oscillation between the promise and the disappointment of biobanks as techno-scientific infrastructures for contemporary biomedical research is frequent in the literature. In this article, we analysed how the precariousness of biobanks is leading to shifts in the focus of biobanking in Spain, where there are calls for some practices to be rearticulated. Drawing upon fieldwork and interviews with biobankers, we looked at which practices are highlighted for change to make biobanks worth maintaining and keep them afloat. We analysed these practices to unpack the values biobankers deploy to make sense of biobanking and turn it into two worthiness criteria: social return and dynamism. These criteria are intertwined and revolve around ethically calibrating the accumulation and sharing practices, 'sharing but not too much'. The porosity of biobanking practices and legislation, not to mention over a decade of austerity measures make biobanks fragile scientific infrastructures in Spain. We examine how biobanking practices are shifting in Spain to stay in the precarious techno-scientific present while challenging assumptions on cryopreservation and preparedness. Our local account highlights the relevance of further inquiries on shifts in biobanking to attend to which kinds of biomedical research and knowledge might be coproduced by such infrastructural reconfigurations.

Is It Possible to Expand Oocyte Donors by Decreasing Number of Oocytes for Own Use? Insights From a Large Single-Center Study.

Background: Currently, in China, only women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles can donate oocytes to others, but at least 15 oocytes must be kept for their own treatment. Thus, the aim of this study was to determine whether oocyte donation compromises the cumulative live birth rate (CLBR) of donors and whether it is possible to expand oocyte donors' crowd. Methods: This was a retrospective cohort study from August 2015 to July 2017 including a total of 2,144 patients, in which 830 IVF-embryo transfer (IVF-ET) patients were eligible for oocyte donation and 1,314 patients met all other oocyte donation criteria but had fewer oocytes retrieved (10-17 oocytes). All 830 patients were advised to donate approximately three to five oocytes to others and were eventually divided into two groups: the oocyte donation group (those who donated) and the control group (those who declined). The basic patient parameters and CLBR, as well as the number of supernumerary embryos after achieving live birth, were compared. These two factors were also compared in all patients (2,144) with oocyte ≥10. Results: In 830 IVF-ET patients who were eligible for oocyte donation, only the oocyte number was significantly different between two groups, and the donation group had more than the control group (25.49 ± 5.76 vs. 22.88 ± 5.11, respectively; p = 0.09). No significant differences were found between the two groups in other factors. The results indicate that the live birth rate in the donation group was higher than that in the control group (81.31% vs. 82.95%, p = 0.371), without significance. In addition, CLBR can still reach as high as 73% when the oocyte number for own use was 10. Supernumerary embryos also increased as the oocyte number increased in all patients (oocyte ≥10). Conclusions: Currently, oocyte donation did not compromise CLBR, and oocyte donation can decrease the waste of embryos. In addition, in patients with 10 oocytes retrieved, the CLBR was still good (73%). Thus, it is possible to expand oocyte donors if the number of oocyte kept for own use was decreased from 15 to 10 after enough communication with patients.

The journey to establishing an IT-infrastructure within the German Biobank Alliance.

BACKGROUND: Biobanks ensure the long-term storage and accessibility of biospecimens and corresponding data sets. Thus, they form the foundation for many research projects which may contribute to improving medical care. With the establishment of the German Biobank Node and Alliance, expertise in biobanking is bundled and strengthened. An important component within this research infrastructure is the set-up of an information technology (IT) network for allowing feasibility requests across individual biobanks. OBJECTIVE: We aim to describe relevant aspects that have shaped the journey to interconnect biobanks, to enhance their visibility within the research-community, to harmonize data, and to enable feasibility searches to support access to available data and biosamples. METHODS: To achieve this task, we resorted to a wide variety of methods: we ran a requirement analysis, decided on the mode of operation for the federated team of IT-developers and on the development approach itself, took related national and international initiatives into account, and concluded with evaluations of the developed software artefacts and the operation of the entire chain of applications. RESULTS: We drew an IT framework including all heterogeneous data aspects derived from our requirement analysis and developed a comprehensive IT infrastructure. The successful implementation benefited from a smooth interaction of a federated IT team distributed across all participating sites that was even able to manage a major technology change mid-project. Authentication and project management services from associated partners could be integrated and the graphic user interface for an intuitive search tool for biospecimens was designed iteratively. The developed code is open source to ensure sustainability and the local implementation is concluded and functioning. The evaluation of the components was positive. CONCLUSIONS: The entire project had given ample opportunity for challenges, predictable and unpredictable-from the mode of operation to changing some of the initial ideas. We learned our lessons concerning personnel, budget planning and technical as well as manual monitoring as well as some requirements arising only during the process of the project. Nevertheless, we can here report a success story of a network infrastructure, highly agile and much easier in local installation than initially anticipated.

United Kingdom Biobank (UK Biobank): JACC Focus Seminar 6/8.

An increasing number of people are now living with cardiovascular disease (CVD), with concomitant CVD-related hospitalizations, operations, and prescriptions. To ultimately deliver optimal cardiovascular care, access to population-based biobanks with data on multiomics, phenotypes, and lifestyle risk factors are crucial. UK Biobank is a cohort study that incorporated data between 2006 and 2010 from over half a million individuals (40 to 69 years of age) at recruitment from across the United Kingdom. As one of the most accessible, largest, and in-depth cohort studies in the world, UK Biobank continues to enhance the resource with the addition of data from various omics platforms (eg, genomics, metabolomics, proteomics), multimodal imaging, self-reported risk factors and health outcomes, and linkage to electronic health records. The vision of UK Biobank is to allow as many researchers as possible to apply their expertise and imagination to undertake research to prevent, diagnose, and treat a wide range of chronic conditions, including CVD.

Does bariatric surgery reduce future hospital costs? A propensity score-matched analysis using UK Biobank Study data.

OBJECTIVES: To estimate the hospital costs among persons with obesity undergoing bariatric surgery compared with those without bariatric surgery. METHODS: We analysed the UK Biobank Cohort study linked to Hospital Episode Statistics, for all adults with obesity undergoing bariatric surgery at National Health Service hospitals in England, Scotland, or Wales from 2006 to 2017. Surgery patients were matched with controls who did not have bariatric surgery using propensity scores approach with a ratio of up to 1-to-5 by year. Inverse probability of censoring weighting was used to correct for potential informative censoring. Annual and cumulative hospital costs were assessed for the surgery and control groups. RESULTS: We identified 348 surgical patients (198 gastric bypass, 73 sleeve gastrectomy, 77 gastric banding) during the study period. In total, 324 surgical patients and 1506 matched control participants were included after propensity score matching. Mean 5-year cumulative hospital costs were €11,659 for 348 surgical patients. Compared with controls, surgical patients (n = 324) had significantly higher inpatient expenditures in the surgery year (€7289 vs. €2635, P < 0.001), but lower costs in the subsequent 4 years. The 5-year cumulative costs were €11,176 for surgical patients and €8759 for controls (P = 0.001). CONCLUSIONS: Bariatric surgery significantly increased the inpatient costs in the surgery year, but was associated with decreased costs in the subsequent 4 years. However, any cost savings made up to 4 years were not enough to compensate for the initial surgical expenditure.

Leveraging natural history biorepositories as a global, decentralized, pathogen surveillance network.

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic reveals a major gap in global biosecurity infrastructure: a lack of publicly available biological samples representative across space, time, and taxonomic diversity. The shortfall, in this case for vertebrates, prevents accurate and rapid identification and monitoring of emerging pathogens and their reservoir host(s) and precludes extended investigation of ecological, evolutionary, and environmental associations that lead to human infection or spillover. Natural history museum biorepositories form the backbone of a critically needed, decentralized, global network for zoonotic pathogen surveillance, yet this infrastructure remains marginally developed, underutilized, underfunded, and disconnected from public health initiatives. Proactive detection and mitigation for emerging infectious diseases (EIDs) requires expanded biodiversity infrastructure and training (particularly in biodiverse and lower income countries) and new communication pipelines that connect biorepositories and biomedical communities. To this end, we highlight a novel adaptation of Project ECHO's virtual community of practice model: Museums and Emerging Pathogens in the Americas (MEPA). MEPA is a virtual network aimed at fostering communication, coordination, and collaborative problem-solving among pathogen researchers, public health officials, and biorepositories in the Americas. MEPA now acts as a model of effective international, interdisciplinary collaboration that can and should be replicated in other biodiversity hotspots. We encourage deposition of wildlife specimens and associated data with public biorepositories, regardless of original collection purpose, and urge biorepositories to embrace new specimen sources, types, and uses to maximize strategic growth and utility for EID research. Taxonomically, geographically, and temporally deep biorepository archives serve as the foundation of a proactive and increasingly predictive approach to zoonotic spillover, risk assessment, and threat mitigation.

Donor program for fecal microbiota transplantation: A 3-year experience of a large-volume Italian stool bank.

BACKGROUND: Due to the increasing rise of C. difficile infection, stool banks and donor programs have been launched to grant access to fecal microbiota transplantation (FMT). Our aim is to describe characteristics and outcomes of the donor program at our stool bank. METHODS: Donor candidates underwent a four-step selection process, including a clinical interview, blood and stool testing, a further questionnaire and a direct stool testing the day of each donation. From March 2020, specific changes to this process were introduced to avoid the potential transmission of COVID-19. We evaluated the rate of excluded candidates at each step of the screening, as well as the number of total fecal aliquots provided by qualified donors. RESULTS: Overall, 114 donor candidates were evaluated. Seventy-five candidates declined to join the program for logistic or personal issues, three were excluded after the questionnaire and seven for positive stool exams. Finally, 29 (25%) subjects qualified as stool donors, and provided 70 stool samples. Fifteen samples were excluded after direct molecular stool testing. A total of 127 aliquots was finally obtained. CONCLUSIONS: Donor recruitment for FMT is a challenging process, and only a small rate of candidates are eligible as donors.

The Biobanque québécoise de la COVID-19 (BQC19)-A cohort to prospectively study the clinical and biological determinants of COVID-19 clinical trajectories.

SARS-CoV-2 infection causing the novel coronavirus disease 2019 (COVID-19) has been responsible for more than 2.8 million deaths and nearly 125 million infections worldwide as of March 2021. In March 2020, the World Health Organization determined that the COVID-19 outbreak is a global pandemic. The urgency and magnitude of this pandemic demanded immediate action and coordination between local, regional, national, and international actors. In that mission, researchers require access to high-quality biological materials and data from SARS-CoV-2 infected and uninfected patients, covering the spectrum of disease manifestations. The "Biobanque québécoise de la COVID-19" (BQC19) is a pan-provincial initiative undertaken in Québec, Canada to enable the collection, storage and sharing of samples and data related to the COVID-19 crisis. As a disease-oriented biobank based on high-quality biosamples and clinical data of hospitalized and non-hospitalized SARS-CoV-2 PCR positive and negative individuals. The BQC19 follows a legal and ethical management framework approved by local health authorities. The biosamples include plasma, serum, peripheral blood mononuclear cells and DNA and RNA isolated from whole blood. In addition to the clinical variables, BQC19 will provide in-depth analytical data derived from the biosamples including whole genome and transcriptome sequencing, proteome and metabolome analyses, multiplex measurements of key circulating markers as well as anti-SARS-CoV-2 antibody responses. BQC19 will provide the scientific and medical communities access to data and samples to better understand, manage and ultimately limit, the impact of COVID-19. In this paper we present BQC19, describe the process according to which it is governed and organized, and address opportunities for future research collaborations. BQC19 aims to be a part of a global communal effort addressing the challenges of COVID-19.

La pandemia de COVID-19 ha puesto en jaque a los sistemas de salud en el mundo; la vinculación entre la investigación biomédica y la práctica asistencial ha probado ser un requisito fundamental para dar respuesta a la misma de manera eficiente y rápida. En este sentido, los biobancos se constituyen como un componente clave ya que favorecen el almacenamiento de grandes volúmenes de muestras biológicas gestionadas en base a criterios que garanticen su óptima calidad, armonización y seguridad, respetando requisitos éticos y legales que aseguran los derechos de los ciudadanos. La cesión de estas muestras a distintos grupos de investigación promueve el desarrollo de nuevas herramientas diagnósticas y terapéuticas y vacunas. Frente a la llegada del SARS-CoV-2 a la Argentina, el Biobanco de Enfermedades Infecciosas estableció rápidamente la colección COVID-19 constituida por muestras de plasma, suero y células mononucleares de sangre periférica de personas cursando la enfermedad o recuperadas. En solo seis meses se enrolaron 825 donantes, lo que significa alrededor de 14.000 viales de material biológico almacenados y a disposición de los investigadores que lo soliciten. A tal efecto, se realizaron seis actos de cesión a diversos grupos pertenecientes a instituciones de investigación, mientras que tres se encuentran en evaluación. Las muestras cedidas han permitido, por ejemplo, el desarrollo de kits serológicos de producción nacional; lo que pone de manifiesto que el rápido establecimiento de esta colección, bajo un sistema de gestión eficiente, constituye una herramienta muy valiosa en la respuesta a esta nueva enfermedad

The COVID-19 pandemic has driven an unprecedented health crisis. Cooperation between biomedical research and healthcare practice has been shown to be a fundamental requirement to provide an efficient and timely response. In this regard, biobanks are key components since they allow the storage of large volumes of biological samples with guaranteed optimum quality, harmonization and safety, ensuring ethical and legal requirements which protect citizen rights. The transfer of these samples to different research groups fosters the development of new diagnostic and therapeutic tools as well as vaccines. Upon SARS-CoV-2 arrival to Argentina, the Biobank of Infectious Diseases rapidly established the COVID-19 collection comprised by plasma, serum and peripheral blood mononuclear cells samples obtained from people within the acute phase of the infection or who have already recovered. In only 6 months, 825 donors were enrolled, representing around 14,000 vials of biological material stored and available to researchers who might require it. In this line, 6 transfer agreements have been already performed to different groups belonging to national research institutions, while 3 are under evaluation. The transferred samples have allowed, for instance, the development of nationally produced serologic kits, which shows that the rapid establishment of this collection, under an efficient management system, represents a highly valuable tool in the response to this new disease.

Utilizing a large-scale biobanking registry to assess patient priorities and preferences for cancer research and education.

Patients consented to biobanking studies typically do not specify research conducted on their samples and data. Our objective was to gauge cancer biobanking participant preferences on research topics. Patient-participants of a biobanking study at a comprehensive cancer center who had an appointment within the last 5 years, had a valid email address, and with a last known vital status of alive, were emailed a newsletter containing a link to a survey about preferences and priorities for research. The survey assessed demographics and research interest in three domains: cancer site, cancer-related topics, and issues faced by cancer patients. 37,384 participants were contacted through email to participate in the survey. 16,158 participants (43.2%) opened the email, 1,626 (4.3% overall, 10% of those who opened the email) completed the survey, and 1,291 (79.4% of those who completed the survey) selected at least one research priority. Among those who selected at least one research priorities for cancer-relevant topics, the most commonly selected were cancer treatment (66%), clinical trials (54%), and cancer prevention (53%). Similarly, the most selected priorities for cancer-related issues faced by patients were physical side effects of cancer (57%), talking to the oncologist (53%), and emotional challenges due to cancer (47%). Differences by gender were observed, with females reporting more interest in research generally. Cancer patients participating in a biobanking protocol prioritized research on treatments, prevention and side effects, which varied by gender.

Clinical and molecular practice of European thoracic pathology laboratories during the COVID-19 pandemic. The past and the near future.

BACKGROUND: This study evaluated the consequences in Europe of the COVID-19 outbreak on pathology laboratories orientated toward the diagnosis of thoracic diseases. MATERIALS AND METHODS: A survey was sent to 71 pathology laboratories from 21 European countries. The questionnaire requested information concerning the organization of biosafety, the clinical and molecular pathology, the biobanking, the workload, the associated research into COVID-19, and the organization of education and training during the COVID-19 crisis, from 15 March to 31 May 2020, compared with the same period in 2019. RESULTS: Questionnaires were returned from 53/71 (75%) laboratories from 18 European countries. The biosafety procedures were heterogeneous. The workload in clinical and molecular pathology decreased dramatically by 31% (range, 3%-55%) and 26% (range, 7%-62%), respectively. According to the professional category, between 28% and 41% of the staff members were not present in the laboratories but did teleworking. A total of 70% of the laboratories developed virtual meetings for the training of residents and junior pathologists. During the period of study, none of the staff members with confirmed COVID-19 became infected as a result of handling samples. CONCLUSIONS: The COVID-19 pandemic has had a strong impact on most of the European pathology laboratories included in this study. Urgent implementation of several changes to the organization of most of these laboratories, notably to better harmonize biosafety procedures, was noted at the onset of the pandemic and maintained in the event of a new wave of infection occurring in Europe.

Each patient is a research biorepository: informatics-enabled research on surplus clinical specimens via the living BioBank.

The ability to analyze human specimens is the pillar of modern-day translational research. To enhance the research availability of relevant clinical specimens, we developed the Living BioBank (LBB) solution, which allows for just-in-time capture and delivery of phenotyped surplus laboratory medicine specimens. The LBB is a system-of-systems integrating research feasibility databases in i2b2, a real-time clinical data warehouse, and an informatics system for institutional research services management (SPARC). LBB delivers deidentified clinical data and laboratory specimens. We further present an extension to our solution, the Living µBiome Bank, that allows the user to request and receive phenotyped specimen microbiome data. We discuss the details of the implementation of the LBB system and the necessary regulatory oversight for this solution. The conducted institutional focus group of translational investigators indicates an overall positive sentiment towards potential scientific results generated with the use of LBB. Reference implementation of LBB is available at https://LivingBioBank.musc.edu.

Artificial intelligence powered statistical genetics in biobanks.

Large-scale, sometimes nationwide, prospective genomic cohorts biobanking rich biological specimens such as blood, urine and tissues, have been established and released their vast amount of data in several countries. These genetic and epidemiological resources are expected to allow investigators to disentangle genetic and environmental components conferring common complex diseases. There are, however, two major challenges to statistical genetics for this goal: small sample size-high dimensionality and multilayered-heterogenous endophenotypes. Rather counterintuitively, biobank data generally have small sample size relative to their data dimensionality consisting of genomic variation, lifestyle questionnaire, and sometimes their interaction. This is a widely acknowledged difficulty in data analysis, so-called "p¼n problem" in statistics or "curse of dimensionality" in machine-learning field. On the other hand, we have too many measurements of individual health status, which are endophenotypes, such as health check-up data, images, psychological test scores in addition to metabolomics and proteomics data. These endophenotypes are rich but not so tractable because of their worsen dimensionality, and substantial correlation, sometimes confusing causation among them. We have tried to overcome the problems inherent to biobank data, using statistical machine-learning and deep-learning technologies.

A standardised model for stool banking for faecal microbiota transplantation: a consensus report from a multidisciplinary UEG working group.

BACKGROUND: Faecal microbiota transplantation is an emerging therapeutic option, particularly for the treatment of recurrent Clostridioides difficile infection. Stool banks that organise recruitment and screening of faeces donors are being embedded within the regulatory frameworks described in the European Union Tissue and Cells Directive and the technical guide to the quality and safety of tissue and cells for human application, published by the European Council. OBJECTIVE: Several European and international consensus statements concerning faecal microbiota transplantation have been issued. While these documents provide overall guidance, we aim to provide a detailed description of all processes that relate to the collection, handling and clinical application of human donor stool in this document. METHODS: Collaborative subgroups of experts on stool banking drafted concepts for all domains pertaining to stool banking. During a working group meeting in the United European Gastroenterology Week 2019 in Barcelona, these concepts were discussed and finalised to be included in our overall guidance document about faecal microbiota transplantation. RESULTS: A guidance document for all domains pertaining to stool banking was created. This document includes standard operating manuals for several processes involved with stool banking, such as handling of donor material, storage and donor screening. CONCLUSION: The implementation of faecal microbiota transplantation by stool banks in concordance with our guidance document will enable quality assurance and guarantee the availability of donor faeces preparations for patients.

[The Breast Cancer Cohort Study in Chinese Women: the construction and progress of the pan-shared biobank].

Objective: Biobank construction plays an irreplaceable role in the research of accurate prevention and treatment of diseases. Shared biobank network based on a large crowd queue is the way of the future. This subject is one of the key contents of national precision medicine "The Breast Cancer Cohort Study in Chinese Women: (BCCS-CW)" , aiming to solve the bottleneck of insufficient standardization and sharing. Methods: The establishment of "entity library-information library-extension library" , the widely Shared network of biobank of breast cancer specific disease cohort, and the establishment of strict standard setting and quality control standard to construct the standardized biobank. Results: This biobank provides a shared biobank resource for breast cancer risk assessment, prediction and early warning, early screening, classification, individualized treatment, efficacy and safety prediction and monitoring and other accurate prevention and treatment programs and clinical decision-making system research. Conclusion: The data of this biological sample bank is refined and complete, and the sample size of cases is sufficient, which can meet the research needs of medical big data, genomics, metabonomics, epigenetics and other fields.
