Dr. Ganetzky runs a research group focused on understanding the biochemical sequelae of mitochondrial complex V deficiency. She is highly involved in metabolic training and leads the biochemical fellowships. She also sees patients with mitochondrial disease and other inborn errors of metabolism, with particular clinical interest in primary lactic acidosis, mitochondrial hepatopathy and disorders of pyruvate metabolism.

Inherited mitochondrial diseases can lead to disruptions in energy metabolism and abnormalities in the mitochondrial redox state because of impaired oxidation of NADH, the main reducing equivalent in the cell. As a result, the NADH/NAD+ ratio becomes elevated, which causes widespread secondary metabolic abnormalities in NAD+ utilizing pathways. Measuring the NADH/NAD+ ratio directly can be challenging due to its instability. However, there is a direct proportionality between the intramitochondrial NADH/NAD+ ratio and the ratio of the physiologic ketone bodies beta-hydroxybutyrate (BHB) and acetoacetate (AcAc). Therefore, assessing the ketone body ratio offers a more stable approach to estimate the mitochondrial redox state.

Measurement of the ketone body ratio is analytically challenging due to the instability of AcAc and the presence of BHB structural isomers like alpha-hydroxybutyrate (AHB), gamma-hydroxybutyrate (GHB), and beta-hydroxyisobutyrate (BHIB). Therefore, there was no clinically validated assay available to measure BHB, AcAc, and their ratio as a single test. Existing assays typically quantify AcAc and BHB separately using methods such as spectrophotometry, enzymology, or indirect measurements through gas chromatography. However, these methods often result in reduced accuracy of the ratio and require larger specimen quantities.

To enhance clinical care, a new rapid LC-MS/MS-based multiplex ketone body panel has been developed and clinically validated. This innovative panel only requires 10

The process of translating mass spectrometry (MS)-based proteomic assays from basic research to the clinical laboratory remains a significant challenge for many laboratorians. The road to using innovative assays to aid in patient treatment is often fraught with obstacles, be they technical, financial, or regulatory. Over the past several years, our laboratory has had success in the research and development, validation, and commercialization of a multi-marker assay of high-density lipoprotein (HDL)

Dr. Tim Van Den Bossche is currently working as postdoctoral researcher in the CompOmics lab of Prof. Lennart Martens in the field of microbial community proteomics, commonly known as metaproteomics. Here, he led the first-ever, community-driven, multi-site experiment that compared the effects of different state-of-the-art metaproteomics analysis pipelines (wet-lab and computational), and also compared the results with the taxa obtained from metagenomic and metatranscriptomic experiments - commonly known as the CAMPI study. With this momentum, he co-founded the Metaproteomics Initiative (www.metaproteomics.org) to further help accelerate the metaproteomics field. Next to this benchmark study and his work in the Initiative, he develops bioinformatics tools to metaproteomics data analysis.

Through connecting genomic and metabolic information, metaproteomics is an essential approach for understanding how microbiomes function in space and time. The international metaproteomics community is delighted to announce the launch of the Metaproteomics Initiative (www.metaproteomics.org), the goal of which is to promote dissemination of metaproteomics fundamentals, advancements, and applications through collaborative networking in microbiome research.

We will discuss past, present and future of this project as well as possible clinical implementations.

Academics are more likely to suffer from mental health disorders yet are less likely to seek treatment. Stigma is one of the highest ranked barriers to help-seeking for mental health problems. Sharing faculty stories is a powerful mechanism to reduce stigma, promote more open communication, and foster cultural change around mental health issues. Olya did her MD, PhD, and postdoc in translational medicine and mass spec. Currently she works as a scientific communications officer and devotes her spare time to academic mental health advocacy.

My research focuses on developing multimodal chemical instrumentation from a chemometric perspective, improving high spatial resolution mass spectrometry imaging capabilities, and applying semi-targeted complex mixture analysis methodologies. I'm interested in the development of new chemical imaging instrumentation because I see an increasing need for imaging instruments that produce high quality data that can can be easily interpreted by clinicians and applied scientists. To that end, I am working to build multimodal instruments, develop experiment methodologies, and create data analysis pipelines that are able to produce higher-quality chemical information more rapidly and with fewer steps than existing imaging instruments and workflows.

Most mass spectrometry imaging (MSI) is performed one pixel at a time at a rate below 1,000 pixels per second. Recently, researchers at the M4i institute at Maastricht University developed an MSI technique called fast mass microscopy [1] which acquires many mass spectra in parallel and is capable of imaging at over 1 million pixels per second. This improvement of >1,000 times imaging speed opens new opportunities for MSI in clinical applications as experiments that would otherwise take months can now be done in less than an hour. This seminar will focus on fast mass microscopy and strategies for its future clinical translation.

Metabolomics is a relatively newcomer of the Omics family for large-scale characterization of small molecules of biological systems. A key step in metabolomics is to determine metabolic differences among different samples. We want to detect and quantify as many metabolites as possible, ideally covering the entire chemical space of the metabolome. High-coverage metabolome analysis will benefit many research areas, including disease biomarker discovery, population-based health analytics and clinical applications. This presentation will focus on the discussion of current challenges and potential solutions for translating global metabolomics into clinical applications.

Joshua is currently the Chief of Chemistry at NortonHealthcare. He earned his PhD in chemistry from Carnegie Mellon University. He conducted postdoctoral research at Massachusetts Institute of Technology before completing a two-year clinical chemistry fellowship at University of Washington and 4 years as Assistant Professor at Weill Medical College. Joshua has special expertise developing and overseeing mass spectrometry assays in the clinical laboratory.

Setting up a clinical mass spectrometry lab presents a host of challenges with a great deal of attention understandably paid to developing and validating high quality assays. Rarely do laboratorians consider the reimbursement aspect of the testing they are setting up. This is unfortunate given the importance financial success has in determining whether or not an organization will invest in such testing. Reimbursement and appropriate billing is especially important to consider when it comes to more complex testing such as urine toxicology; appropriate billing of this testing is essential to ensure labs get adequately reimbursed and stay in compliance with applicable laws and regulations. This CONNECT webinar will focus on lessons learned establishing urine toxicology testing from the billing aspect. It will include an overview of how such testing should be billed, mistakes that are often made when establishing such testing, and the tools available to labs to help ensure testing is properly billed (and more likely reimbursed). Ample time will be given to ensure the audience can share their own struggles in this area and can ask questions about the topics raised.

Peter VERHAERT was full professor Analytical Biotechnology and Innovative Peptide Biology at Delft University of Technology [Netherlands; 2005 – 2016] before founding his company ProteoFormiX (www.proteoformix.com). His Flemish research startup is alumnus of JLABS, the J&J Innovation Center, and was born at JLABS@BE on the Campus of Janssen Pharmaceuticals in Beerse [Belgium; 2017].

Peter is recognized worldwide as one of the pioneers in Peptidomics, Peptides in Biology being the common theme in his >35 years of research.

Prior to taking up his academic position in Delft and ultimately starting his own research company in Beerse, Peter's international career already combined academic and industrial positions:
He obtained an MSc in Biology (Zoology Group) and a PhD in Comparative Neurobiology at the University of Leuven, where he held a position as assistant professor [Belgium; 1983-1987].
He then took on a postdoc position at the Laboratory of Toxicology and Biochemistry in the Biology Department of the University of Waterloo [Canada; 1988].
Upon returning to the University of Leuven, he became an associate professor in Histology and Biological Mass Spectrometry [Belgium; 1988-1999].
After an industrial sabbat year at the Flemish Biotech Innogenetics in Ghent [Belgium; 1998-1999], Peter was appointed group leader Proteomics at the Dutch Pharma company Organon (now MSD) in Oss [Netherlands; 2000-2004].

His other professional activities include:
• Co-founder and president of the European Pharmaceutical Proteomics Laboratories (EPPL) [2000-2004];
• Proteomics expert at the Flemish Institute of Biotechnology (VIB) [2000-2004];
• Visiting professor Biomedical Proteomics at the Biomedical Research Institute at the Faculty of Medicine of Hasselt University [Belgium; 2004-2014];
• Editor-in-chief of the Elsevier Open Access Journal EuPA Open Proteomics [2013-2016]
• Co-director of the Center of Excellence in Biomedical Mass Spectrometry (CEBMMS) at the Faculty of Medicine (Clinical Sciences Department) of Lund University [Sweden; 2016];
• Honorary professor Mass Spectrometry Histochemistry at the Maastricht Multimodal Molecular Imaging Institute (M4i) of Maastricht University [Netherlands; 2017-].

The lack of biomarkers still prevents the discovery and development of therapeutics and diagnostics for several serious diseases. Some of the latter can only be correctly diagnosed under the microscope by scrutinizing tissue sections of biopsy or even autopsy material.

Histopathologists all over the globe archive precisely annotated samples preferably in FFPE (formaldehyde-fixed paraffin-embedded) tissue banks. These represent a virtually unlimited resource of accurately diagnosed and stratified patients of all (stages of) diseases, which unfortunately today remains largely underexplored in biomarker research.

What if there would be a molecular discovery technology that could detect and identify biomarker candidates from the very same FFPE tissue sections?
What if this would be a label-free multiplex technology?
What if this technology would work on material stored for decades?
What if this technology could be spatially resolved?
What if this technology could generate molecule specific images that can be overlaid with other imaging modalities?
What if this technology would have single cell resolution in combination with single cell sensitivity?
What if this technology could localize molecules which are specifically produced and released from cells?
What if this technology would be multi-omics?

In this webinar I will argue that a technology already exists today that appears to combine all of the above.

Mass spectrometry histochemistry (MSHC), which combines atmospheric pressure MALDI with high resolution top-down MS, deserves this extra attention, as it may be(come) a welcome complement (or even alternative) to current LC-MS/MS biomarker discovery strategies that analyze extracts of tissues and body fluids.

Once live with mass spectrometry-based testing, clinical laboratories face the challenge of ensuring adequate data review and accurate resulting. Inevitably, labs will encounter patient results that raise the question - should I report this? This interactive discussion will attempt to address issues related to questionable patient results including those with (i) unknown interferences that might impact the accuracy of the results, (ii) low internal standard recovery, and (iii) potential carryover. The discussion will be led by three individuals currently overseeing clinical toxicology mass spectrometry testing. Examples of challenges they have faced and (occasionally) approaches they have found useful will be presented as a starting point for discussion.

Leroy "Lee" Edward Hood is an American biologist who has served on the faculties at the California Institute of Technology (Caltech) and the University of Washington. He is currently Professor and Chrief Strategy OFficer at the Institute for Systems Biology. Dr Hood has developed ground-breaking scientific instruments which made possible major advances in the biological sciences and the medical sciences. These include the first gas phase protein sequencer (1982), for determining the sequence of amino acids in a given protein; a DNA synthesizer (1983), to synthesize short sections of DNA; a peptide synthesizer (1984), to combine amino acids into longer peptides and short proteins; the first automated DNA sequencer (1986), to identify the order of nucleotides in DNA; ink-jet oligonucleotide technology for synthesizing DNA and nanostring technology for analyzing single molecules of DNA and RNA.

Dr Hood believes that a combination of big data and systems biology has the potential to revolutionize healthcare and create a proactive medical approach focused on maximizing the wellness of the individual. He coined the term "P4 medicine" in 2003.

The vision of this project is that we will develop the infrastructure to employ a data-driven approach to optimizing the health trajectory of individuals for body and brain. We have two large populations (5,000 and 10,000) that have validated this approach for body and brain health, respectively. These studies have led to us pioneering the science of wellness and prevention. This project will require the acquisition of key partners for execution, which will be delineated. We are approaching the Federal Government for funding, as we did for the first Human Genome Project. This project will lead to striking new knowledge about medicine, it will catalyze the initiation of start-up companies and it will catalyze a paradigm shift in healthcare from a disease orientation to a wellness and prevention orientation. This will catalyze the largest paradigm shift in medicine, ever.

We will be talking with Thomas Durant and Edward Lee about recent advances in machine learning (ML) for mass spectrometry (MS) data analysis. The primary focus will be the alignment of these two fields (ML and MS) and how this offers a promising synergy that can be used to optimize workflows, improve result quality, and enhance our understanding of high-dimensional datasets, as well as their inherent relationship with disease biology. We will also dig deeper to understand a basic overview of ML and an ML-based experiment. Overall, we will have a opportunity go through the fundamental principles of supervised ML, outline the steps that are classically involved in an ML-based experiment, and discuss the purpose of good ML practice in the context of a binary MS classification problem.

I'm interested in the development of new chemical imaging instrumentation because I see an increasing need for imaging instruments that produce high quality data that can can be easily interpreted by clinicians and applied scientists. To that end, I am working to build multimodal instruments, develop experiment methodologies, and create data analysis pipelines that are able to produce higher-quality chemical information more rapidly and with fewer steps than existing imaging instruments and workflows.

Graphics are what grab attention at your poster, what people see when they skim your paper, and what they remember from your presentation. Although it is possible to create professional quality graphics using a variety of approaches and software, there are only a few that provide flexibility to be useful across all scientific disciplines. Many of these are expensive, are not available on all popular operating systems, or use proprietary file formats. In this interactive MSACL Early Career Network event, you will learn how to use free and open source graphics software, specifically Inkscape and GIMP, to produce high quality scientific graphics that meet scientific journal requirements. We will cover (1) importing and saving different graphic file formats; (2) recoloring, cropping, and layering raster graphics; (3) editing and annotating plots; (4) creation of simple scientific workflow diagrams and schematics, and (5) assorted software

New therapies targeting immune checkpoint (IC) proteins have revolutionized oncology therapeutics, but heterogeneous expression of IC proteins between individuals and tumor types complicates development of cancer immunotherapies. Although typically framed in the context of companion diagnostics, the need to reliably quantify drug targets is critical in the preclinical and clinical development of new drugs, especially for the design and interpretation of clinical trials. Quantification of drug target status can inform interpretation of target abundance and outcomes. Targeted mass spectrometry (MS) uniquely enables sensitive and precise measurement of IC proteins, coregulators and immune cell markers. MS measurements can be performed in formalin-fixed, paraffin-embedded (FFPE) samples and are multiplexed, thereby enabling simultaneous analysis of multiple IC proteins, immune cell markers, and related pathway markers in the same sample.

New immunotherapeutics targeting the IC protein TIGIT are in clinical development with PD-1/PD-L1 inhibitors for solid tumor indications, but without reliable TIGIT protein biomarkers to guide trial design and interpretation. We used targeted mass spectrometry (MS) to precisely quantify TIGIT, DNAM1, PVR, PVRL2, PD-1, PD-L1, and PD-L2 in 97 primary non-small cell lung cancers (NSCLC) and matched tumor draining lymph node metastases (TDLN). Only 56% of NSCLC cases expressed TIGIT, which was quantifiable almost exclusively in TDLN. TIGIT, DNAM1 and PVR abundance varied over approximately 25-fold and they were co-expressed only in some tumors. PD-1/PD-L1 axis proteins were quantified in virtually all samples over an even broader abundance range than TIGIT/DNAM1 axis proteins. Combined quantitation of TIGIT/DNAM1 and PD-1/PD-L1 axis proteins may indicate the sufficiency of the target system to respond to combined anti-TIGIT anti-PD-1/PD-L1 therapeutics.

Dr. Shuford will accept this award with a presentation : Breakthrough or Bust? Thyroglobulin Measurement by LC-MS/MS.

Proteolysis-aided workflows can effectively eliminate autoantibody complexes and allow for interference-free protein quantification by mass spectrometry with surrogate peptides. Owing to the prevalence of autoantibodies in thyroid cancer patients and associated interference among immunoassay platforms, the purported poster child for mass spectrometry-based protein measurements has been Thyroglobulin (Tg). However, many other factors contribute to the utility of measurement procedures for tumor makers such as Tg, including throughput, ruggedness, trueness, and sensitivity. This presentation will focus on these limitations

I grew up in San Diego, CA and Arlington, VA. I attended Santa Clara University where I received a B.S. in chemistry. I joined the MD PhD program at UCSD in 2007 and completed a PhD in Biomedical Sciences with a specialization in Anthropogeny. I continued at UCSD for residency training in internal medicine and completed a year as chief resident in 2019-2020. In June of 2020, I started my Endocrinology Fellowship. I plan to pursue a career in academic medicine that combines clinical endocrinology with outcomes research in Vitamin D metabolism.

Using the MrOS database and mass spectrometry, we demonstrate that 1,25(OH)2 Vitamin D, 24,25(OH)2 Vitamin D, and their associated metabolite ratios are associated with gut microbial diversity in older community dwelling men. Notably, 25(OH) Vitamin D levels did not show this association. We also demonstrate that firmicutes which frequently produce butyrate are associated with higher levels of activated Vitamin D. Overall, the project demonstrates that quantifying Vitamin D metabolites may provide more clinically relevant measures of Vitamin D metabolism.

I am a PhD student in the Microbiology, Immunology, and Cancer Biology (MICaB) program at the University of Minnesota. The goal of my research is to study the molecular mechanisms of PARP inhibition in HGSOCs containing BRCA1/2 mutations and comparing these responses to wild-type BRCA1/2 ovarian cancers. By studying the differential responses that HGSOCs have on PARP inhibition at the level of the proteome, we can ascertain which type of HGSOCs would benefit most with PARP inhibition with minimal risk of relapse. Finally, studying changes in the proteome upon PARP inhibition will reveal other sets of genes besides BRCA1/2 that are involved in homologous recombination dysfunction.

Imaging mass spectrometry is a powerful technology that enables the visualization of biochemical processes directly in tissues by combining the molecular specificity of mass spectrometry with the spatial fidelity of microscopic imaging. Especially when studying lipids, there are many isobaric and isomeric molecules that complicate spectral analysis, with each isoform having a potentially unique cellular function. While traditional tandem mass spectrometry (MS/MS) approaches can distinguish amongst these compounds in select instances, this is often not the case. Our group is developing gas-phase reactions that afford the ability to provide improved molecular specificity without manipulating the sample. These gas-phase transformations are fast, efficient, and specific, making them ideally suited for implementation into imaging mass spectrometry workflows to enable novel structural identification and separation based on chemical reactivity. While traditional analytical analyses oftentimes simply use the mass spectrometer as a detector of molecular mass, we instead use the mass spectrometer as a reaction vessel to perform unique gas-phase transformations to provide unparalleled levels of chemical resolution.

Dr Catarina Horro Pita possesses a BSc in Chemistry and Environmental Chemistry and a PhD in Synthetic Organic Chemistry. After concluding her PhD, she initiated her professional career as a Synthetic Chemist, prior to moving into Analytical Chemistry and Bioanalysis. She has been working in the field of Bioanalysis for 15 years, holding both scientific and managerial positions. Catarina currently works as a PK Project Manager at A4P Consulting. During her career, she has gained significant experience in the development, validation and management of LC-MS/MS assays for the analysis of both xenobiotic compounds and small molecule biomarkers. In addition, due to her expertise in Organic Chemistry, she also has an extensive knowledge of derivatization techniques for the improvement of LC-MS/MS methods.

Derivatization is a simple chemical reaction, often used in Bioanalysis to transform a “not so ideal” candidate for LC-MS/MS analysis into a molecule with enhanced phys-chem properties, which leads to improved detectability of the compound.

The objective of this presentation is to describe some of the most commonly used derivatization procedures and explain the benefits and drawbacks of these techniques.

When performing analysis by LC-MS/MS, the ideal analyte should be chemically stable and have moderate retention on the LC column. The molecule should also be ionisable under ESI or APCI conditions and have an efficient fragmentation upon collision. In addition, the target compound should be selectively separated from other xenobiotics or endogenous products present in the extracted matrix. When the analyte does not meet all of the above criteria, derivatisation can be used to modify its chemical structure and address these issues.

A range of derivatization processes will be reviewed, indicating their bioanalytical applications and type of chemical reactions involved. In addition, examples of derivatization reagents and reaction conditions will be described.

Although the application of derivatization procedures can lead to an improved bioanalytical performance, these techniques also present a range of disadvantages, such as extended method development times, lengthy extraction procedures and increased method variability.

Despite all the recent technological improvements in the field of Bioanalysis, derivatization remains a very powerful tool to overcome problems associated with analyte instability, poor chromatographic performance, inadequate analyte ionization or unacceptable method selectivity. However, the application of derivatization procedures can often lead to an increase in assay complexity and may reduce method robustness. Therefore, both the advantages and disadvantages of these procedures should always be considered before their application to a bioanalytical method.

Ivayla Roberts is a doctoral researcher at the University of Liverpool in Prof. Kell system biology group. Originally coming from computer science background (MSc, Montpellier France) Iva transitioned to molecular biology research via a Translational Molecular Medicine MRes (Manchester, UK).
Iva’s research interests are metabolomics, mass-spectrometry, and the application of statistical and machine learning computational approaches to metabolomics.
Iva’s PhD is focused on metabolomics in COVID-19.

The diagnosis of COVID-19 is normally based on the qualitative detection of viral nucleic acid sequences. Properties of the host response are not measured but are key in determining outcome. Although metabolic profiles are well suited to capture host state, most metabolomics studies are either underpowered, measure only a restricted subset of metabolites (‘targeted metabolomics’), compare infected individuals against uninfected control cohorts that are not suitably matched, or do not provide a compact predictive model.

We here provide a well-powered, untargeted metabolomics assessment of 120 COVID-19 patient samples acquired at hospital admission. The study aims to predict patient’s infection severity (i.e. mild or severe) and potential outcome (i.e. discharged or deceased).

High resolution untargeted LC-MS/MS analysis was performed on patient serum using both positive and negative ionization. A subset of 20 intermediary metabolites predictive of severity or outcome were selected based on univariate statistical significance and a multiple predictor Bayesian logistic regression model. The predictors were selected for their relevant biological function and include cytosine and ureidopropionic acid (reflecting viral load), kynurenine (reflecting host inflammatory response), and multiple short chain acylcarnitines (energy metabolism) among others.

Currently, this approach predicts outcome and severity with a Monte Carlo cross validated area under the ROC curve of 0.792 (SD 0.09) and 0.793 (SD 0.08), respectively. A blind validation study on additional 90 patients predicted outcome and severity at ROC_AUC of 0.83 (CI 0.74 – 0.91) and 0.76 (CI 0.67 – 0.86). Prognostic tests based on the markers discussed in this paper could allow improvement in the planning of COVID-19 patient treatment.

When analysing patient samples the concentration of the analyte measured should mirror the concentration during sample collection; therefore consideration should be given to the pre analytical conditions of the samples. One such consideration in multi-analyte studies is the potential for interconversion between analytes, which can compromise this quantification, leading to potential overestimation of one analyte and underestimation of another. In this session the root causes of interconversion shall be discussed, from the reversible hydrolysis of lactones e.g. statin drugs to cleavage of ester bonds by esterases. We will be examining the entire life-cycle of a patient sample to allow identification of problem areas in a methodology. We shall examine how to create a robust and accurate method with particular focus on stabilisation protocols and practicalities for the clinical laboratory. How to calculate levels of interconversion shall be demonstrated and the ability to assess impact upon data discussed.

Introduction.
Breast cancer is a very serious problem worldwide. Breast cancer is accompanied by the metastatic lesion of the lymph nodes in 40-50% of cases. Currently, histology analysis is used during the surgery in order to verify the occurrence of metastasis in lymph nodes. Faster and more specific methods are urgently required for the identification of metastatic lesion in lymph nodes directly during the surgery.

Methods.
We present the new method based on the internal extractive electrospray ionization (iEESI) combined with high-resolution mass spectrometry analysis. It allows us to perform rapid (less than 5 minutes) molecular profiling of breast tissue and signal lymph nodes tissue with regard to presence of metastatic lesion. The distinctive feature of proposed ionization method allows the direct extraction of whole-volume biopsy tissue samples rather than just their surface. It makes it possible to substantially increase the sensitivity, accuracy and reproducibility of analysis compared with existing analogues. New analytical advancements were implemented which allow the sequential ionization of lipids, metabolites and proteins from the same single biopsy tissue sample.

Results.
Rapid diagnosis of the metastatic lesion of the signal lymph nodes upon invasive breast cancer on the biopsy tissue samples was performed in 50 patients. The signals of differential metabolites associated with the occurrence of lymphatic lesion were identified using high-resolution tandem MS analysis and reference LC-MS analysis. Bioinformatics approaches were developed in order to study the complex relationships between the identified metabolites. This led us to create of a molecular model of metastasis process.

Conclusions.
A minimally invasive method has been developed for the diagnosis of metastatic lesions of signal lymph nodes in invasive breast cancer based on direct mass spectrometric analysis. A mechanism for metastasis to the signal lymph nodes in breast cancer was proposed.
Novel Aspect.
A new method for mass spectrometric analysis of biopsy samples based on internal extractive electrospray ionization has been developed.

Angela is interested in the development of highly sensitivity, high throughput, well validated mass spectrometry assays for steroid analysis. Application of these assays to answer important clinical questions is critical to her research. She feels the truly translational aspect of the work conducted at the Steroid Metabolome Analysis Core (SMAC) means the work is both analytically enjoyable and socially beneficial.
Angela has an analytical chemistry master’s degree from Swansea University (2005). In 2009 she received her PhD from Swansea University investigating steroid metabolism in the human endometrium using mass spectrometry. This was followed by post-doctoral work at the University of Birmingham working for Prof Wiebke Arlt, which cumulated in setting up the SMAC facility in 2016. The SMAC lab now conducts steroid research from wet lab based projects to clinical trials.

Translation of a test from the initial hypothesis to routine clinical use is a long and challenging journey. In this session I will discuss my experiences in the research laboratory focusing on the development of ‘urinary steroids metabolomics’ a combination of mass spectrometry and machine learning for diagnosis of adrenocortical carcinoma (ACC).

The journey starts with the hypothesis developed by Wiebke Arlt and Cedric Shackleton that urinary steroid excretion in patients with adrenal cancers would differ from those with benign adrenal adenomas (ACA). Initial studies were undertaken investigating 32 steroid metabolites using gas chromatography mass spectrometry (GC-MS). Through collaboration with computer scientists Michael Biehl and statisticians Alice Sitch and John Deeks, we were able to identify a malignant steroid fingerprint that differentiated ACC from ACA. When compared to current available imaging technologies, this urine steroid metabolomic assay demonstrated improved diagnostic sensitivity and specificity.

GC-MS is technically challenging and time consuming making it an expensive assay unsuitable for routine clinical use. Therefore, we selected the most relevant steroids when distinguishing between ACC and ACA and developed and validated a liquid chromatography tandem mass spectrometry (LC-MS/MS) assay for a subset of 15 steroids. Firstly, this was cross-validated to GC-MS to compare quantitation and diagnostic performance. Secondly, we prospectively validated the assay in a cohort of approximately 2000 unbiasedly recruited patients with adrenal tumours. Finally, we were able to determine the optimal stage in the patient pathway to place our assay to aid the diagnosis of ACC.
We are currently working towards the implementation of this assay into routine clinical biochemistry. It has taken us 10 years from the initial concept to its implementation, only possible through the work of a multi-disciplinary team. There have been many challenges on this pathway, I will discuss how we overcame these in this session.

Gwen Wark is a consultant clinical biochemist employed within the Blood Sciences department of Berkshire and Surrey Pathology Services. She has worked at the Royal Surrey County Hospital in Guildford for over 22 years where she is now Director of the Supraregional Assay Service (SAS) Peptide Hormones Laboratory which specialises in the investigation of hypoglycaemia (includes a forensic case load) and the role of insulin-like growth factors and their binding proteins. Since 2002, she has also been the Scheme Director of the UK National External Quality Assessment Service (UK NEQAS) Guildford Peptide Hormones Scheme which covers the analytes insulin, C-peptide, gastrin, insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-3 (IGFBP-3). Since 2019, she has also been Director of the UK NEQAS Trace Elements schemes. She is involved in developing accuracy-based proficiency testing for all scheme analytes.

Gwen is also involved in promoting the development of reference methods/measurement systems. She is a member of the British Standards Institution (BSI) CH/212 committee which is responsible for standardisation in the field of in vitro diagnostics and reviewing/developing ISO standards. She is a member of the IFCC working group (collaboration with ADA and EASD) for the standardisation of insulin assays and a guest member of the NIDDK led C-peptide standardisation committee. In collaboration with the National Institute for Biological Standards and Control (NIBSC), she has been involved in the development of the WHO International Standards for IGF-I, insulin, C-peptide and proinsulin. She collaborated in the workshop that culminated in the ‘Consensus Statement on the Standardisation and Evaluation of Growth Hormone and Insulin-like Growth Factor Assays’ and also development of mass spectrometric assays for the measurement of IGF-I. Current LC-MS/MS assay development is focussed on developing further LC-MS/MS peptide assays for implementation into the routine laboratory e.g. insulin and C-peptide.

In the routine laboratory, the use of LC-MS/MS is becoming more widespread and is often used to overcome issues encountered with immunoassays. In this presentation, issues with peptide hormone analyses by LC-MS/MS and consensus statement recommendations will be discussed. Insulin and IGF-I will be used to highlight analytical approaches that be adopted to enable implementation of LC-MS/MS into the routine laboratory.

Dr. Uta Ceglarek, PhD, EuSpLM is senior scientist at the University Hospital Leipzig, Institute of Laboratory Medicine, Clinical Chemistry and Molecular Diagnostics (ILM). She is board certified in Clinical Chemistry and Laboratory medicine (EuSpLM), in Toxicology and passed her postdoctoral lecture qualification in Clinical Chemistry and Laboratory Medicine.
Her research efforts are focused on the development of new mass spectrometric concepts for metabolome and proteome analysis in human body fluids and the investigations of metabolic alterations and lipid-modification in dyslipidemia, metabolic syndrome and cardiovascular diseases.

Over the past two decades clinical mass spectrometry becomes increasingly importance as analytical tool in routine diagnostics. LC-MS/MS offers a rapid, effective and economical way to analyze metabolic alterations of pre-defined target metabolites in biological samples. Recent developments open the way to implement quantification of proteins into clinical routine, too. Until now, access to clinical applications of LC-MS/MS have been restricted to specialist centers. The increasing availability of commercial assays, certified instruments, and a growing number of commercial solutions for mass spec lab automation will help to overcome this limitation.

However, for implementation into 24/7 patient care special requirements to laboratory diagnostic approaches have to be addressed. This presentation will give an overview to the current status aof LC-MS/MS applications like newborn screening, therapeutic drug monitoring, steroid analysis and quantitative protein analysis. Experiences from more than 20 years of implementation and maintenance of LC-MS/MS in our 24/7 diagnostic laboratory will be discussed. Perspectives for future developments in laboratory medicine directing to the clinical aim of predictive, preventive and personalized medicine by metabolomic and proteomic approaches will be depicted.

Lucia Grenga is a researcher in the laboratory of Innovative Technologies for Detection and Diagnostics at the French Alternative Energies and Atomic Energy Commission (CEA). She is interested in the development of tandem mass spectrometry‐based methodologies and their integration with other omics approaches for the characterization of clinically relevant microbiomes.

Proteomics offers a wide collection of methodologies to study biological systems at the finest granularity. Faced with COVID-19, the most worrying pandemic in a century, a collective mass spectrometry effort was launched to study COVID-19 and propose alternative solutions for the detection of SARS-CoV-2. Since then, proteomics researchers have made significant progress in understanding how its causative virus SARS-CoV-2 hijacks the host's cellular machinery and multiplies exponentially, how the disease can be diagnosed, and how it develops, as well as its severity predicted. Numerous cellular targets of potential interest for the development of new antiviral drugs have been documented. The main findings gathered by our group and other proteomists will be discussed while pointing out how they could represent game-changers in the COVID-19 battlefield and in deciphering the long-term consequences of the infection.

After successfully completing my Master in Pharmaceutical Care, I graduated as pharmacist in 2020. Mainly due to the interesting research performed during my Master’s thesis in the laboratory of Toxicology of prof. Christophe Stove, I decided to further pursue a career in science and research and started my PhD a few months after graduating. Currently, my work is mainly focusing on automation of microsampling-based analysis, including hematocrit prediction of dried blood microsamples (conventional dried blood spots and samples collected via volumetric absorptive microsampling) and the development of automated microsampling-based LC-MS/MS methods for the analysis of vitamins. Apart from research, I have also been involved in the organization of the last two Young Scientist Symposia of the European Bioanalysis Forum (EBF). I am (co-)author of 6 peer-reviewed publications.

I graduated in 2001 as a Master of Sciences in Chemistry at Ghent University. From 2001 to 2007 I did my PhD in the Laboratory of Analytical Chemistry at the Faculty of Pharmaceutical Sciences at Ghent University, followed by a post-doc in the same laboratory. Since October 2014 I'm a postdoctoral fellow at the Laboratory of Toxicology at Ghent University, where I am the quality manager and technical supervisor of the ISO17025 and ISO15195 accredited reference laboratory (Ref4U) section and the forensic service section of the lab. Besides this, I am the scientific secretary of the International Federation of Clinical Chemistry and Laboratory Medicine Committee for Standardization of Thyroid Function Tests.

I have expertise in development and validation of targeted GC or LC/MS (higher order reference) measurement procedures and their applications, with profound experience with method comparisons. Within the reference laboratory, the focus of the research activities is standardization and harmonization of thyroid function tests. Within the forensic applications, the focus is on determination of alcohol markers and new psychoactive substances. In 2020, I also participated in the development of a Sars-COV-2 LC/MS method.

Several biomarkers for alcohol (ab)use have been used throughout the years, including direct and indirect biomarkers. As indirect biomarkers show a low specificity and sensitivity for the detection of alcohol abuse, attention has shifted towards direct biomarkers such as ethanol itself and products derived thereof (ethyl glucuronide, ethyl sulfphate, etc.). Within the group of direct biomarkers, phosphatidylethanol (PEth) has been valued more and more since it increases the sensitivity of uncovering alcohol consumption and monitoring abstinence. With a half-life of 7-8 days, PEth provides a long detection window meaning it can take weeks for positive PEth values to drop below the decision limit for monitoring abstinence (20 ng/mL). Consequently, the question arises whether abstinence can be confirmed based on two consecutive PEth positive results.

In the first part of this session a detailed overview will be given of the abovementioned alcohol biomarkers. In the second part, the results of a large-scale PEth monitoring study will be discussed.

Methods
A large scale PEth monitoring study was set up in which over 500 participants agreed to stay sober for one month. During this period, they took 3 finger prick samples via self-sampling at home using volumetric absorptive micro sampling devices (VAMS, Mitra

Introduction
Surgery of solid tumors is a difficult process and the quality of surgery is central for patient outcome. Despite important improvements in surgical practices, the completeness of tumor removal remains scarce and surgeons are still struggling in the decision making. The gold standard currently remains the collection of biopsies and examination by expert pathologist. This process is long and laborious while showing an important rate of wrong assessment. We recently introduced SpiderMass technology based on water-assisted laser desorption-ionization (WALDI) which enables to retrieve the necessary molecular information directly in-vivo and in real-time. Yet, the device was demonstrated for manual profiling of tissues. However, for intraoperative diagnostics and excision margins evaluation, the device must be integrated onto a robotic device to provide precise imaging of the defined area within the body.

Methods
The SpiderMass system is composed of a remote laser microprobe, a transfer line and the MS instrument. The laser microprobe is fibered and equipped with a handpiece and tuned to 2.94

In vitro diagnostics in the European Union (EU) is facing fundamental change with the implementation of Regulation (EU) 2017/746 on in vitro diagnostic medical devices, known as IVDR. With its full entry into force from May 2022, the IVDR will affect a population of 447 million people in 27 countries. The regulation addresses - beyond commercially distributed products - devices manufactured in healthcare facilities. In many ways, it is not yet clear how the IVDR will actually impact in-house MS-based measurement procedures. This presentation will discuss recent documents and guidance and provide an update on the implementation process - which is the responsibility of member states. An IVDR-compliance checklist will also be presented.

Dirk Lefeber, Ph.D., is Professor at the Radboud University Medical Center, Translational Metabolic Laboratory, Department of Neurology. After a PhD in chemical and analytical glycosciences at Utrecht University, followed by a post-doctoral training in polysaccharide infectiology at Utrecht UMC, he took a position as staff member Glycosylation Disorders at the Radboud UMC to establish an independent research group. He completed a training to Laboratory specialist clinical genetics in 2008, founded the Radboudumc Expertise Center for Disorders of Glycosylation, formally recognized by the Dutch government, and received several awards, including the SSIEM award (2010&2016) and prestigious personal VIDI and VICI grants from the Netherlands Scientific Organisation. He has established the world-wide quality control scheme for CDG diagnostics within ERNDIM.

Congenital Disorders of Glycosylation (CDG) form a fast growing group of genetic defects, that are characterized by abnormal glycosylation of proteins and lipids. With already more than 140 different genetic diseases discovered in all glycosylation pathways, the need for better biomarkers is increasing. This includes diagnostic biomarkers with increased specificity and sensitivity, as well as biomarkers that can predict disease progression and therapy response.

This presentation will mainly focus on CDGs due to defects in protein N-glycosylation. Screening for defects in protein N-glycosylation is occurring broadly via analysis of plasma transferrin by isofocusing, HPLC or capillary electrophoresis. Increased specificity and sensitivity is obtained by high-resolution QTOF mass spectrometry of intact plasma transferrin, which allows for screening and CDG subtyping in a single diagnostic test. For example, diagnostic glycan profiles are obtained for intellectual disability due to MAN1B1-CDG and exercise intolerance due to PGM1-CDG.

More sophisticated glycomics and glycoproteomics techniques are being applied and developed for CDG gene discovery, by stratification of patient groups. Moreover, these technologies are applied to diagnose CDG defects that don

Dr. Markus Kostrzewa is currently the Senior Vice President of Microbiology & Diagnostics R&D, Regulatory Affairs and Scientific Affairs at Bruker. He completed his PhD in 1993 at the Justus-Liebig-University in Giessen Germany, and his post-doc at the institute of Human Genetics in 1997. He joined Bruker in 1998, where he developed DNA analysis by MALDI-TOF mass spectrometry, Clinical Proteomics methods, consumables and software for mass spectrometry profiling of body fluids and tissues, and microorganism identification by MALDI-TOF mass spectrometry, which is produced and marketed by Bruker under the brand name, MALDI Biotyper.

Already at the end of the last century, MALDI-TOF mass spectrometry protein profiles were proposed as specific fingerprints for microorganisms which can be used for their unequivocal identification by comparison of dedicated reference databases. Nevertheless, it took a further decade until the technology entered routine diagnostic laboratories, suddenly considered as a revolution in microbiology diagnostics. After introduction into the first routine laboratories, it took only a few. years until it became the new microbial identification standard.

A prerequisite of success was the offering of a comprehensive system, a package consisting of the mass spectrometer including user friendly software for data acquisition, interpretation and report, reference databases, standard procedures, and consumables. Reliable service for the instrument and software, but also application support had to be offered to gain confidence of microbiologists and lab technicians in the novel technology. Regulatory approvals are prerequisite for diagnostic in most countries. This could only be achieved by companies who took over the central responsibility for the new diagnostic system.

Three main arguments made MALDI-TOF MS successful, being faster, better and more cost-effective than the previously applied techniques, i.e. biochemical and other phenotypical tests. Superior quality of MALDI-TOF based identification was demonstrated already with early versions of reference databases. Over the years, the libraries for different organism groups have been significantly expanded, today covering thousands of species from different microorganism groups. Species previously not considered to be pathogenic for humans have been detected as causative for infections, and even new microbial species have been discovered. Time to identification has been shortened by at least one day, and even more for slow-growing organisms and for microbes isolated directly from positive blood cultures. Although the initial investment for a MALDI-TOF instrument is considerably higher than for former standard identification systems, the very low running costs make it more cost-effective at least for medium and high throughput laboratories.

While MALDI-TOF is undisputed as the standard routine identification tool for microbiology laboratories, further applications have been proposed which might increase the value of MALDI-TOF MS for clinical microbiology. The considerable diversity in mass spectra that can be observed for many species was proposed for subtyping and epidemiology purposes. Several different approaches have been published for antibiotic resistance or even susceptibility testing. A first IVD-CE marked test for detection of a resistance mechanism has been introduced. Simple detection of specific marker peaks in the mass spectra enables detection of particular strains exhibiting antibiotic resistance. Other procedures comprise the observation of incorporation of isotope-labelled nutrients or the semi-quantitative determination of microbial biomass for susceptibility testing. Recently, besides proteins also lipids get into the focus of MALDI-TOF MS analysis as specific markers, for resistance detection as well as for identification or typing purposes.

My talk will describe the evolution of MALDI-TOF mass spectrometry in the microbiology lab, the conditions for its success and status of today, and I will give an outlook for its future potential.

The interdisciplinary nature of the research projects is focused on the elucidation of the metabolic interaction between the gut microbiota and their human host. His laboratory develops new Chemical Biology tools to extend the scope of metabolomics research for discovery of unknown biomarkers and bioactive metabolites.

One of the most exciting scientific developments in the past decade has been the understanding that gut microbiota profoundly impact human physiology. The complex consortium of trillions of microbes possesses a wide range of metabolic activity. This metabolic interspecies communication represents a tremendous opportunity for the discovery of unknown bioactive molecules as only limited information on this co-metabolism has been elucidated on a molecular level. Mass spectrometry-based metabolomics analysis is the method of choice for the analysis of known and discovery of unknown metabolites. Chemical Biology tools are still limited in metabolomics compared to other

A native of Florida, Kelly completed her undergraduate studies in Chemistry at the University of Florida. After graduating with honors in 2009, Kelly joined the Department of Chemistry at Vanderbilt University as a graduate student. Her research in the lab of John A. McLean focused on the development of ion mobility-mass spectrometry (IM-MS) methods for the identification of metabolite, lipid, and peptide biomolecular signatures of disease from complex biological samples. After receiving her Ph.D. in 2014, Dr. Hines completed a one-year postdoctoral fellowship in the Mayo Clinic Regional Metabolomics Core where she established quantitative MS methods for lipidomics and protein metabolism using isotope labeling. In 2015, Dr. Hines joined the lab of Libin Xu at the University of Washington.

I'm currently a second-year graduate student in the Hines lab at the University of Georgia. My focus now is looking into lipid composition variability caused by external growth factors or gene mutation using reversed-phase liquid chromatography mass spectrometry.

I graduated from Samford University in Birmingham, Alabama in spring 2020 with a bachelor’s degree in chemistry and biochemistry and joined UGA’s Chemistry Ph.D. program in the fall of 2020. As an undergraduate, I worked on organometallic research involving transition metal catalyzed synthesis reactions. Now as a member of the Hines lab, my research focuses on high-throughput flow-injection mass spectrometry and lipid isomer identification through determining carbon-carbon double bond location via ion-mobility.

Our goal is to better understand the ways in which lipids and small molecules contribute to diseases affecting human health and use this knowledge to develop diagnostic and prognostic tools based on molecular signatures of the disease. To achieve this, the Hines Lab develops and applies bioanalytical methods using ion mobility-mass spectrometry (IM-MS) to enhance the throughput and dimensionality of lipidomics and metabolomics experiments. One focus of the group is antibiotic resistance, where we are characterizing the metabolic alterations in antibiotic resistant pathogens and developing IM-MS methods for antibiotic susceptibility testing and small molecule screening.

Dr. Hamid's PhD studies in Prof. M. Samy El-Shall’s research laboratory in Virginia Commonwealth University were focused on studying ion-molecule kinetics, thermochemistry, and structures using drift tube ion mobility spectrometer measurements associated with quantum mechanics calculations. Then, Ahmed joined Purdue University to work under the supervision of Prof. R. Graham Cooks where he focused on the applications of mass spectrometry to various biological systems, in particular on differentiation of microorganisms using various ambient ionization techniques coupled to mass spectrometry which resulted in novel approaches in the ionization and the identification of bacteria and fungi with high prediction rates without sample preparation. To learn new skills, Dr. Hamid joined the team of Dr. Richard D. Smith in Pacific Northwest National Laboratory to work on the development of novel Structures for Lossless Ion Manipulations (SLIM) which allows previously unattainable ion mobility resolution and remarkable ion manipulations. Moreover, as a senior scientist in MOBILion Systems, Ahmed transferred and further developed the SLIM technology. In summary, Dr. Hamid has more than 14 years of experience researching in the fields of technology development and the applications of mass spectrometry and ion mobility spectrometry which resulted in more than 29 peer-reviewed publications in high impact journals and 7 patents.

CDC estimates that each year 48 million people get sick from a foodborne illness where 128,000 are hospitalized leading to 3,000 deaths. They are caused by pathogenic bacteria, parasites, or viruses that enter the body through the consumption of contaminated food or beverages followed by growth inside the host body. Therefore, rapid methods are crucial for the effective detection of foodborne pathogens in food products to provide safe food supply and to prevent outbreaks of foodborne diseases and the spread of foodborne pathogens. In addition, developing fast robust diagnosis techniques will increase the recovery rates of patients suffering from foodborne infections and will lead to reduced antibiotic resistance.

The membrane of these bacteria contains varying lipid composition that can be utilized as diagnostic biomarker for foodborne disease diagnosis. However, their full characterization remains analytically challenging due to their enormous structural diversity and complexity (e.g., varying acyl chain positions and/or double bond geometries). This presentation will demonstrate the advantages of interfacing liquid chromatography and structurally-based ion mobility with tandem mass spectrometry in the resolution of isomeric lipids. Moreover, this presentation will demonstrate the developments of ambient ionization techniques when coupled to high-resolution ion mobility spectrometry. We expect these developments to enable portable diagnosis devices that can be used for sensitive detection and superior separation power in the analysis of contaminated food samples and foodborne clinical samples without any prior sample preparation. This will enable high throughput analyses that is affordable and can be performed by less-skilled users, such as nurses and farmers.

Hoda Safari Yazd is a Ph.D. candidate in analytical chemistry at the University of Florida and working under the supervision of Prof. Richard Yost and Dr. Timothy Garrett. She received her B.Sc. in chemistry from Sharif University of Technology in 2015 and her M.Sc. in computational chemistry from the same school in 2017. Hoda's research at UF primarily focuses on combining analytical chemistry tools and scientific programming for the metabolomic discovery of rare disorders. She is currently working on two projects; the first project concentrates on the detection of new biomarkers in meningiomas to improve early detection of this disease by employing machine learning as a tool on mass spectrometry-based metabolomics data. The second project is focused on the characterization of rare X-chromosome deletion disorders using metabolomics and lipidomics workflows by UHPLC-HRMS on neural progenitor cells. Hoda is one of the founding members and main organizers of the MSACL Early Career Network (MSACL-ECN).

Dr. Garrett has over 20 years of experience in the field of mass spectrometry spanning both instrument and application development. He received his PhD from the University of Florida, under Dr. Richard A. Yost, working on the first imaging mass spectrometry-based ion trap instrument. He has also developed MALDI-based approaches to analyze proteins in bacteria and small molecules in tissue specimens. His current interests include the translation of LC-HRMS, MALDI, DESI and LMJSSP in metabolomics to clinical diagnostics. He is an Associate Professor in the Department of Pathology at the University of Florida, and an Associate Director for the Southeast Center for Integrated Metabolomics (SECIM).

Hoda Safari Yadz and Tim Garrett, from the Garrett lab in Florida, join us today for a presentation and discussion of their work on the metabolomic and lipidomic characterization of an X-chromosome deletion disorder in neural progenitor cells, hosted by the JMSACL podcast group.

X linked disorders are considerably rare and research analysing human samples is under-
represented. Research undertaken in this study used neural progenitor cells from an afflicted patient to begin exploring this rare disorder. While most experimental work focuses on the
neurodevelopmental impacts of X-chromosome associated diseases, this work demonstrates that
they should also be considered metabolic disorders owing to their perturbations on metabolite and
lipid biochemistry. This work aims to use mass spectrometry to improve our understanding of these
conditions and guide novel interventions by characterizing disease associated metabolic alterations.

Prenatal exposure to ethanol has long been associated with several long-term negative health consequences for the newborn including physical, cognitive, social, and behavioral impairments. The prevalence of FASD in North America may be as high as 5% of the population which represents an enormous public health concern (Flannigan, Coons-Harding, Anderson, Wolfson, Campbell, Mela, & Pei, 2020). Early identification of those affected is critical to address the special needs of these children to improve their outcomes. Outside of maternal self-report, there are limited strategies to objectively identify PAE at or near the time of birth.

Current testing strategies to detect prenatal exposure to ethanol is limited in scope and utility Unfortunately, a rapid immunoassay test does not exist leaving us with a very expensive and time-consuming liquid chromatography tandem mass spectrometry screening method. The objective of this presentation is to demonstrate a newly developed and validated a method for the detection of ethyl glucuronide in umbilical cord tissue using Laser Diode Thermal Desorption-Tandem Mass Spectrometry. The Laser Diode Thermal Desorption (LDTD), allows for a significant decrease in time and expense when compared to the current methodology.

The method was developed and validated according to the guidelines of the Scientific Working Group on Forensic Toxicology. Briefly, Umbilical Cord Tissue was weighed out (0.5 g), deuterated internal standard is added and homogenized in 3 mL of deionized water. Following centrifugation, the supernatant was purified using a solid phase extraction technique. The final reconstituted extract (8

He is going to start to work at Peking University Third Hospital as a urologist in August 2021. Dr. Li is also proud to win the Young Investigator Grant in MSACL EU 2019 and to have a podium presentation of his research there. Recently, he has become a member of the Japanese Society for Biomedical Mass Spectrometry (JSBMS). While studying at Kyoto University he became interested in the clinical application of MALDI-TOF/MS, especially when using it in the urinary lipid analysis. Dr. Li and his supervisors, especially Dr. Kenji Nakayama who is an Asia Outreach Committee of MSACL and also one of the JSBMS council members, developed a simple relative-quantitative MALDI-TOF/MS system for urinary lipidomics, and they are applying it in the screening of urinary biomarkers for genitourinary disorders. Now, they are aiming at promoting the "qShot MALDI” system as a simple application for the MALDI analysis.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) has been used for lipid analysis since the 2000s. However, the poor reproducibility and quantitative ability hinder its application in clinical biomarker screenings. To improve the clinical usage of MALDI-TOF/MS, especially for quantitative detection of the urinary phospholipids (PLs) and lysophospholipids (LPLs), we have adopted three main strategies including the selection of a proper matrix, a specially designed plate, and a spike of ionization standards. This system, named

Mr. Huidong Gu is a Principal Scientist in the Clinical Biomarker Immunoassays and Mass Spec Department at Bristol-Myers Squibb Company. For the past 17 years, Huidong has been working in the area of LC-MS/MS bioanalysis of small molecules, biologics and biomarkers with over 30 peer-reviewed publications. Huidong developed a novel approach for calculating and mitigating isotopic interferences in LC-MS/MS quantitative analysis. This approach has a significant impact in the area of microdosing absolute bioavailability studies using LC-MS/MS analysis of both the oral dosed non-labeled drug and the IV microdosed stable labeled drug. His recent work of in-sample calibration curve (ISCC) with multiple isotopologue reaction monitoring (MIRM) technique allows the instant and accurate measurement of biomarkers, biotherapeutics and small-molecule drugs in biological samples without using external calibration curves. This methodology can bring unique values of eliminated external calibration curves, simplified the workflows and improved throughput in the areas where absolute quantitation and overall sample turnaround still remain great challenges.

External calibration curves are commonly used in LC-MS/MS quantitative bioanalysis. In this presentation, a novel methodology of In-Sample Calibration Curves (ISCC) using Multiple Isotopologue Reaction Monitoring (MIRM) of a SIL-analyte for instant LC-MS/MS bioanalysis will be discussed. The theoretical isotopic abundances of a SIL-analyte in its MIRM channels can be accurately calculated based on the isotopic distributions of its daughter ion and neutral loss. The isotopic abundances in these MIRM channels can also be accurately measured with a triple quadrupole mass spectrometer. By spiking a known amount of the SIL-analyte into each sample, an ISCC can be established based on the relationship between the calculated isotopic abundances and the measured LC-MS/MS peak areas in each sample for the quantitative bioanalysis. With this novel MIRM-ISCC-LC-MS/MS methodology, instant, accurate and reliable LC-MS/MS bioanalysis of biomarkers, biotherapeutics and small molecule drugs can be achieved without using external calibration curves. Moreover, this methodology can bring unique values of eliminated external calibration curves, simplified workflows and improved throughput in the areas where absolute quantitation and overall sample turnaround still remain great challenges. The potential applications in quantitative proteomics, clinical laboratories and other areas will also be discussed.

Cam has recently discovered mass spectrometry imaging and found a home with data analysis. He hopes to continue MSI development and exploration through the completion of his undergraduate degree and pursue analytical chemistry in graduate school. Cam enjoys time in the outdoors when not camping out behind a computer screen.

Mass spectrometry imaging returns large dimensionally complex datasets. Traditional analysis in imaging utilizes a mindset focused on target molecule identification that parses data with a narrow view of molecular exploration. These data analysis methods are specifically focused on exploring differences between a traditional organic acid matrix when compared to using nanoparticles for MSI, which results in very different ionization of small molecules. Analysis methods have taken a shotgun approach using both supervised and unsupervised machine learning to reveal critical trends in MSI datasets. A workflow is being prepared which enables select regions of interest to be compared using powerful machine learning algorithms to offer a holistic approach to data analysis and class comparison.

Kate's primary job is as an educator at a Primarily Undergraduate Institution (PUI). In her spare time, she works with students on mass spectrometry imaging projects.

Mass spectrometry imaging (MSI) is a powerful analytical method for the simultaneous analysis of hundreds of compounds within a biological sample. Despite the broad applicability of this technique, there is a critical need for advancements in methods for small molecule detection. Some molecular classes of small molecules are more difficult than others to ionize, e.g., neurotransmitters (NTs). The chemical structure of NTs (i.e., primary, secondary, and tertiary amines) affects ionization and has been a noted difficulty in the literature. In order to achieve detection of NTs using MSI, strategies must focus on either changing the chemistry of target molecules to aid in detection or focus on new methods of ionization. This presentation will introduce a new method of ionization, using gold nanoparticles (AuNPs), and the bigger picture of NPs for MSI.

Lipids play a vital role in maintaining cellular functions. Altered lipid metabolism is currently considered a hallmark of many diseases, which highlights the importance of the characterization of lipid composition in understanding, diagnosing, and treating pathologies. Discrimination of isomeric species is challenging in lipidomics. In this talk, I will introduce the microdroplet electrochemical methods capable of resolving different types of isomers commonly encountered in lipid samples using electrospray ionization mass spectrometry. The methods take advantage of the voltage-controlled and dramatically accelerated electrochemical derivatization of lipid isomers in microdroplets to achieve structural elucidation. Applications of the electrochemical mass spectrometry methods in real sample analysis will also be included.

Shane Ellis completed his Undergraduate studies (B.Nanotechnology) and PhD in the field of ambient ionisation mass spectrometry and lipidomics the University of Wollongong, Australia. In 2012 he began a post-doctoral positional at the FOM-Institute AMOLF where he worked on the development of innovative active-pixel detectors for charged particle detection with applications in imaging mass spectrometry and ion mobility spectrometry. From 2014-2019 he was an Assistant Professor within the M4I Institute (Maastricht University, The Netherlands) where he led the Instrumentation and Application Development Group. His research develops and applies state-of-the-art mass spectrometry imaging methods to reveal localised biochemical processes within complex tissues and how they altered with disease. His group has developed a variety of innovative methods that significantly enhance the sensitivity and spatial resolution of MSI experiments and enabled precise and comprehensive structural identification of the many molecules detected by MSI. This research was supported by numerous Dutch and European grants. In 2020 he returned to Australia as an ARC Future Fellow and started a new mass spectrometry imaging group within the new Molecular Horizons Institute where he continues to further develop and apply mass spectrometry imaging technologies and apply them to challenging biological and chemical problems.

Dr Shane Ellis's group develops and applies mass spectrometry imaging (MSI) technologies to study the distributions of various molecular species throughout tissues and cells. His research covers both the development of new instrumentation to improve the performance of MSI (e.g., sensitivity, spatial resolution and molecular coverage) as well as the application of MSI to studying altered molecular processes occurring in diseased tissues and the spatially-resolved classification of such tissues. A particular focus is in the field of lipidomics, where he applies state-of-the-art MSI technologies to visualize and understand altered lipid biochemistry occurring in diseased tissues and cells.

Pieter Dorrestein uses mass spectrometry to eavesdrop on the molecular conversations between microbes and their world. To produce the image, researchers swabbed every surface in the room, including the people, several hundred times, then analysed the swabs with mass spectrometry to identify the chemicals present.

Kiana is currently a post-doctoral researcher in the Dorrestein Lab at UCSD. She is applying a reference data-driven approach to generate food readouts from metabolomics data acquired from clinical biospecimens. These readouts, proxies for diet consumption, are used to investigate interactions between diet, disease, and the gut microbiome. Her primary clinical focus is Inflammatory Bowel Disease (IBD), but she is also involved in other projects such as Alzheimer’s disease. Kiana received a PhD in Clinical Medicine Research from Imperial College London where she studied metabolomics and microbiomics. Her research at Imperial focused on uncovering metabolic/bacterial signatures associated with altered human development, such as adverse pregnancy outcomes and Autism Spectrum Disorder.

Untargeted metabolomics experiments suffer from large proportions of unannotated molecules. Using a reference data-driven approach, we increase the spectral annotation rate by assigning potential sources to molecular features. We have applied this approach using a food reference database to generate diet readouts from clinical samples. Surveying the food-associated compounds detected in clinical samples, we can differentiate patients with specific diet types, such as predominantly animal protein- versus plant-based diet. In addition, we can identify specific foods associated with clinical outcomes in disease cohorts. With its broad applications, we envision this approach becoming invaluable in nutrition research as well as many other fields once additional reference datasets become available.

The novel coronavirus SARS-CoV-2, the causative agent of COVID-19 respiratory disease is evolving during the current pandemic. New variants show enhanced replication and the potential to evade therapeutic antibodies. In the near future, variants may even evade first generation vaccines. The currently approved direct acting antiviral remdesivir targets the viral RNA-dependent RNA polymerase which is subject to rapid evolution as it is encoded by the viral RNA genome. In order to develop therapeutic approaches which act in a pan-coronavirus manner we and our colleagues at the QBI Coronavirus Research Group (QCRG) have mapped the human proteins (host factors) which multiple Coronaviruses rely on for replication. Through a rapid drug repurposing effort we have identified zotatifin, a clinical eIF4A inhibitor as a host factor targeted therapeutic. Zotatifin which is based on the natural product rocaglamide A works as a molecular glue to trap eIF4A on its target, the (+) RNA viral genome. Other examples of targeting essential host factors, including those for immune evasion will be discussed.

When transitioning from discovery proteomics to targeted protein biomarker quantification, the MRM-based LC/MS method plays an important role in clinical research. To ensure analytical reproducibility and robustness, implementing standard flow-based triple quadrupole LC/MS system has tremendous benefit when involving a large cohort. This webinar will discuss the analytical performance under standard-flow and low LC flow conditions using the Agilent 6495 triple quadrupole LC/MS system.

Renee Ruhaak holds a PhD from the Leiden University Medical Center (LUMC, supervisor Prof. M. Wuhrer) and did a post-doc at UC Davis in the lab of Prof. C.B. Lebrilla prior to joining the department of Clinical Chemistry and Laboratory Medicine at the LUMC. She is currently an associate professor with a research focus on the application of mass spectrometry within the clinical setting. This entails both development and implementation of quantitative protein mass spectrometry, as well as the role of mass spectrometry in metrology and test standardization.

Quantitative protein mass spectrometry is a promising, yet complex technology that enables precision diagnostics. It allows for the multiplexed and direct quantitation of analytes at the molecular level, potentially including identification of proteoforms. Therefore, MS based tests are now proposed more and more often. Yet, quantitative protein mass spectrometry is a complex technique, which has hampered its applications. To ensure efficient test development, novel tests should target clinical gaps in the contemporary clinical pathways, and each of five key elements of test evaluation, as identified by the European Federation for Clinical Chemistry and Laboratory Medicine should be considered. Here we present our experience in the development and application of quantitative protein mass spectrometry, and aim to take away the concerns that have kept laboratory medicine from implementing this promising technology.

Our research integrates the role of new technologies, workflow and software for the analysis of molecules of biological interest. The overall goal is to develop innovative analytical tools and solutions that will benefit the detection and understanding of disease, and the discovery and development of appropriate therapeutics. All aspects of analytical sciences from sample collection to assay validation are considered in our research where mass spectrometric detection plays a central role. In addition to the application of separation sciences (GC, LC, SFC) combined to mass spectrometry, disruptive approaches based on MALDI or ion mobility for high throughput, multiplexed and low cost analyses of biomarkers and pharmaceuticals are investigated.

Our scientific interests include: separation sciences, sample preparation, automation, bioanalysis, metabolism, metabolomics, analytical proteomics, toxicology, high resolution mass spectrometry, ion mobility mass spectrometry, data independent acquisition techniques (SWATH), MS/MS spectra interpretation, ionization, data analysis and mass spectrometry imaging.

The general topic of interest in our research group is the study of the mechanisms involved in photooxidative damage to biological systems, particularly in the human eye. Photooxidative damage is implicated in a number of ocular disorders such as age‐related cataract formation and age‐related macular degeneration (AMD; the leading cause of blindness in older adults). Light damage to biological systems may not manifest itself on a macroscopic level for decades, but the damage is initiated by short‐lived, electronically excited species that participate in Type I or Type II oxidative chemistry. We use a wide variety of experimental methods to study these systems, including laser‐based time‐resolved spectroscopy. By determining the sequence of events that leads to tissue injury and identifying the reactive species along the reaction pathway, we may be able to develop methods to slow down or stop these processes.

Immunoassay urine drug screening has been the mainstay for the detection of drug exposure in patients for decades despite many limitations this approach presents. Positive samples are batched for confirmatory testing by LC-MS/MS targeted methods. Testing is limited to one matrix, a limited list of drugs/metabolites, and manual batch testing restricting interpretation, window of detection and timeliness of results to impact patient care. Utilization of alternative matrices, such as breath and oral fluid, is emerging for specific toxicological questions. Alternative analytical approaches, such as broad-spectrum drug testing with high resolution mass spectrometry, direct-to-mass spec testing with ambient ionization, and ion mobility mass spectrometry have the potential to change the landscape of drug testing in clinical laboratories. This talk will discuss alternative matrices and novel mass spectrometry-based approaches for drug detection.

The use of cannabis and cannabis-derived products by both young and older patients continues to increase. The COVID pandemic has forced people to remain home and be socially distance such that loneliness has increased both the use of alcohol as well as cannabis. A recent news report indicated cannabis sales has increased nearly 25% because of COVID-induced stress and social loneliness. The recent election added four additional states to those allowing legal use of recreational cannabis. There are also many anecdotal reports on the effectiveness of CBD and associated cannabis-derived products which has attracted a passionate following of those who believe using these products helps their ailments.

With these trends it should not be surprising that an increasing number of patients have cannabis-derived chemicals in their body fluids. Although patient ailments may or may not be attributed to cannabis compounds and their metabolites, the

A wide array of analytical instrumentation exist to perform quantitative and qualitative analysis on complex mixtures. The choice of chemical analysis tool, in conjunction with appropriate sample preparation, allows the lens to be focused on a particular sample dimension. Loosely, different sample dimensions can be equated to different classes of analytes contained in a sample. While, we ultimately will likely use very different strategies to characterize e.g. fatty acids vs. proteins in a biological sample, there is potentially value in monitoring each of these analyte classes for correlations with physiological changes that may results as part of a disease or some other abnormality. In fact, if one were trying to classify samples that were normal vs. abnormal, it could be argued that, while the monitoring of one sample dimension might be more diagnostic than another, monitoring and combining data from multiple sample dimensions would like provide additional information to aid the classification. This concept of chemical multi-fingerprinting (CMF) could ultimately help draw lines between different sample classifications, where they were previously difficult to discern. We are currently working to define useful strategies for the combination of multiple analytical techniques for CMF of various sample types. This includes the development of highly featured targeted and non-targeted methods using:

Current studies are focused on the analysis of vitamin D-insensitivity in T lymphocytes from the inflamed joints of patients with rheumatoid arthritis. This may provide an explanation for the limited success of vitamin D supplementation in some clinical trials. Other projects have explored the role of cell metabolism pathways in mediating the immunomodulatory effects of vitamin D, and the opportunities this may provide for improved therapeutic use of vitamin D. The Hewison group has also pioneered a range of studies to explore alternative markers of vitamin D ‘status’. This includes development of novel high throughput liquid chromatography-tandem mass spectrometry technology to measure multiple metabolites of vitamin D – the vitamin D metabolome – and analysis of the role of the serum vitamin D binding protein as a determinant of vitamin D bioavailability within the immune system. Prof. Hewison is a recipient of a Royal Society Wolfson Fellowship. His research is supported by grants from the Medical Research Council and Biotechnology and Biological Sciences Research Council (UK), and the National Institutes of Health (USA).

This is a 2-Day Course with 7 total contact hours.

Overview: Over the past two decades we have seen considerable scientific and technological advancements in imaging mass spectrometry (IMS), as these approaches continue to be implemented in research and industry. There has, however, been limited adoption of these techniques into the clinical arena, in part due to gaps between the mass spectrometrists developing these tools, and the clinical stakeholders, such as surgeons and pathologists, who may one day use them in their practices.

The goal of this course is to bridge these gaps by (1) providing an overview of the principles, strengths, limitations and applications of IMS techniques, such as MALDI-IMS and ambient mass spectrometry (AMS), and (2) offering insight into clinical workflows and potential opportunities for applications. The target audiences include both clinicians, surgeons, and pathologists interested in learning more about IMS applications as well as mass spectrometrists interested in clinical applications of IMS. The first day will focus on MALDI IMS, while the second day will cover ambient MS.

I grew up in rural Michigan and during these formative years greatly enjoyed flyfishing and woodworking. Putting the latter interest to practical use, I constructed several riverboats (for fishing) while in high school and college. Chemistry interested me, especially Analytical Chemistry, as it offered an avenue to continue “building”. Not boats, but chemical instrumentation. To escape the cold I joined the Chemistry graduate program at the University of Florida and worked with Willard Harrison. Professor Harrison didn’t just guide my research, he taught me how to write, present, and think like a scientist. He was a gentleman in every sense of the word. Upon graduation in 2002, I moved to Charlottesville, Virginia to join the laboratory of Professor Don Hunt. At Virginia I met John Syka. Don and John both shared a passion for science that was as infectious as it was inspiring. Together we worked to develop electron transfer dissociation (ETD). ETD worked just as we had hoped and the dissociation technique is now commonly used for proteomics and has been commercially introduced by no fewer than four major instrument vendors. In 2005 I moved to Wisconsin to start my own program. And though we have been productive and impactful with ~ 200 published manuscripts, I am most proud to have produced nearly 20 Ph.D. scientists, and our academic family continues to grow.

The sequencing of the human genome marked the beginning of a collective scientific expedition to understand complex organisms. Genes, of course, merely contain the instructions for which proteins will populate the cell. Untangling the multi-faceted networks that regulate complex organisms and their diseases will require innovative technologies to globally monitor many classes of biomolecules, including nucleic acids, proteins, and metabolites. High-throughput technologies for gene and transcript measurement are well-developed and broadly accessible, and, as such, have had a fantastic and transformative impact on modern biology and medicine. For numerous reasons, methods for global analysis of proteins and metabolites – crucial biological effector molecules – are less evolved and markedly less accessible. The overarching mission of my program is to (1) facilitate expedient, comprehensive analysis of proteins and metabolites by innovating new mass spectrometric technologies and (2) apply these techniques to advance biomedical research.

In this presentation I will describe numerous projects related to the development and application of high-throughput quantitative multi-omics. Examples include new proteomic methods and technologies to permit the deepest analysis of the human proteome to date and the discovery of thousands of alternatively spliced proteins and protein isoforms resulting from single nucleotide polymorphisms. In another example we use high throughput multi-omics to map the proteomes, lipidomes, and metabolomes of nearly 1,000 single gene knockout cell lines for large-scale functional mapping of genes. Finally, we use these same quantitative multi-omic technologies to study the molecular changes that occur during Covid-19 infection in a human cohort.

# Originally scheduled for MSACL2020 US in the Scientific Session : Fentanyl at the Forefront : Using Non-traditional Approaches to Identify Fentanyl Analogs

Introduction

Deaths due to opioid overdoses have been on the rise in the United States, with a particular spike in this trend caused by the emergence of synthetic opioids including fentanyl and analogues. There have been numerous reported cases of synthetic opioids as adulterants in heroin, methamphetamine, cocaine, and counterfeit pills. As a result, they are often times consumed unknowingly, causing mixed toxidromes and confounding diagnosis. Proper routine drug monitoring is essential in addressing the ever-expanding magnitude of the opioid epidemic.

Objectives

The primary objective of this study was to observe prevalence of fentanyl analogs and other false positives in positive fentanyl screens of emergency medicine populations in order to evaluate trends in the dynamic landscape of substance abuse.

Methods

Analysis of remnant clinical samples was approved by the UCSF Institutional Review Board. Urine samples from emergency department (ED) patients with drugs-of-abuse screens performed were monitored from October 2018 to March 2019 for presence of fentanyl (via immunoassay). Samples with a positive fentanyl screen were collected and further characterized by high resolution mass spectrometry (LC-HRMS). Urine samples were diluted 1:5. Chromatography was performed using a Kinetex C18 column with a 10-minute gradient from 2%-100% organic. Data was collected on a SCIEX TripleTOF

Marijuana is increasingly being used for both medical and recreational purposes. In the US, medical use of marijuana is legal in 33 states while recreational marijuana is available in 11 states. With more widespread use, there is growing concern about the effect of marijuana on driving performance.

The University of California-San Diego (UCSD) Center for Medical Cannabis Research (CMCR) recently completed a placebo controlled, double blinded study on the effects of smoked marijuana and driving performance. 200 subjects were randomized to smoking a joint containing placebo, 5.9% or 13.4% THC. Oral fluid, breath, and whole blood samples were collected along with driving performance on a simulator. THC and nine metabolites were measured using isotope dilution tandem mass spectrometry and the sensitivity and specificity of these compounds were examined using cutoffs commonly used by some state

The applications of mass spectrometry in the clinical laboratory continue to expand.
Unfortunately, not all clinical laboratories have mass spectrometers and there are substantial barriers to bringing in this instrumentation. This webinar will discuss some of these barriers and how we have been able to overcome them in our path towards setting up clinical mass spectrometry testing.

This session will serve as an introduction to a 4 part series in which Dr. Hayden will invite attendees to witness in real time his journey bringing mass spec testing to a clinical lab. During these interactive sessions, attendees will be encouraged to help troubleshoot, and offer advice as desired.

Subsequent sessions anticipated include:
1. Getting going with mass spectrometry: Josh learns chromatography
2. Getting going with mass spectrometry: Josh tries to do sample preparation
3. Getting going with mass spectrometry: Josh analyzes peaks

Laura Owen is a Consultant Clinical Scientist at Salford Royal NHS Foundation Trust and honorary senior lecturer at the University of Manchester where she teaches chromatography and mass spectrometry at Master’s level. Laura is also proud to be the chair of the practical training committee of MSACL EU and a past member of the endocrinology committee. While working at Wythenshawe hospital and in collaboration with the Christie hospital she became interested in the limitations of immunoassay measurement especially when using it in the breast cancer population. Laura developed and implemented the UK’s first LC-MS/MS assay for oestradiol in an NHS UKAS accredited laboratory which was made available for patient care and clinical trials.

Oestradiol (also spelled Estradiol) measurement by LC-MS/MS has demonstrated superior sensitivity and specificity over immunoassay but despite this, use of immunoassay remains commonplace. Measuring oestradiol by LC-MS/MS is not without its challenges for which there are several approaches. One particular challenge is the very low levels that there is a clinical need to measure accurately, especially in patients with breast cancer. This presentation will look at the issues around accurate measurement and review how different authors have approached them. It will also examine how oestradiol measurement is used in a breast cancer population as a guide for treatment decisions and how different analytical approaches might impact upon these decisions.

Jona Walk is a resident physician specializing in Internal Medicine at the Canisius Wilhelmina Hospital in Nijmegen. She conducted her PhD research on cellular immune responses after vaccination with the human malaria parasite Plasmodium falciparum at the Radboud university medical center in Nijmegen. She is currently studying vitamin K metabolism as a possible factor in pulmonary damage and coagulopathy in COVID-19, and the potential role for vitamin K supplementation in the treatment of severe SARS-CoV-2 infections.

In this webinar we will present results from our recent study on vitamin K status in SARS-CoV-2 patients. We found severely impaired vitamin K-dependent activation of matrix-Gla-protein (MGP), strongly correlated with increased elastic fiber degradation (as measured by levels of plasma desmosine with LC-MS/MS). Our data suggest a mechanism of pneumonia-induced extrahepatic vitamin K depletion leading to accelerated elastic fiber damage in severe COVID-19 due to impaired activation of MGP. The talk includes a detailed description of the role of vitamin K in hepatic as well as extrahepatic metabolism and its inter-relationship with elastin calcification and elastin degradation as pathological processes that impair elastin

Dr. Rob Haselberg is an assistant professor at the Vrije Universiteit Amsterdam in the department of Chemistry and Pharmaceutical Sciences. He specialized over the last 10+ years in capillary electrophoresis and liquid chromatography hyphenated with mass spectrometry to characterize intact proteins. He is interested in determining protein heterogeneity, getting insights in degradation processes, mapping intentional modifications and studying protein-protein interactions. All of this is done in the context of biopharmaceutical, clinical, and doping analysis.

Classical electrophoresis has a long history in clinical diagnostics. Being used to separate proteins and nucleic acids, it is still an indispensable tool. Over the years, technological advances have allowed for these slab-gel format to be performed in capillaries enabling higher throughput and more accurate quantitation. However, capillary electrophoresis (CE) also has other application areas for clinical diagnostics, especially when hyphenated with mass spectrometry (MS). To show this added values and to understand and appreciate the diversity of this technique, in this seminar the basics of CE and its hyphenation with mass spectrometry will be covered. Separation mechanisms and technical / practical aspects will be covered, using (amongst others) data obtained in our lab. Moreover, some key applications of CE-MS related to clinical diagnostics will be highlighted. They focus on small molecules, lipids, but also intact proteins. Throughout the seminar and at the end there will be ample opportunity to ask questions.

The COVID-19 pandemic has introduced challenge upon challenge for health care systems throughout the US and the world, from implementing new workflows in support of delivering routine care to improving access to testing to navigating constrained supply chains. Clinical laboratories have been critical to the COVID-19 response, as identification of cases with testing is a critical step in containing and managing the SARS-CoV-2 virus. The University of Washington Virology Laboratory has played a key role expanding access to COVID-19 testing across the Pacific Northwest, scaling from performing 5,000 tests per month to 5,000 tests per day and growing. Open source software tools have supported this rapid growth along every step of our journey. In this talk, we will discuss the key capabilities R and Python have enabled that have helped us navigate the daily challenges of managing staffing and turnaround times, adjusting operations in response to supply chain limitations, and enabling testing at scale for the population outside of typical health care settings.

Speaker: Dr. Dan Holmes
