Or did you just perform a glycan release to make the analysis of your protein a lot easier? You have no idea how to interpret your data when a glycan is present? Fear no more! We are here to provide you with the basics in the field of mass spectrometric glycomics and glycoproteomics. The course will start with a historical overview on glycan research (i.e. how did glycans work their way up to being acknowledged as important study objects) and we will guide you through the maze of different nomenclatures. Moreover, although glycans are well known for their complexity, we will reveal to you the “rules of glycan structures” based on known biosynthetic pathways. This will be followed by an in-depth discussion on glyco(proteo)mic mass spectrometric technologies and workflows. In addition, different sample preparation steps and data analysis approaches will be covered. We will close-up with a session about glycomic biomarker discovery. The course will run over two days and time will be split between lectures and workshops (e.g. how do you recognize a glycan in a mass spectrum and how do you assign it). While not everything can be covered within these two days we will ensure that you will know your “glyco-basics” in the end. Moreover, participants are encouraged to submit any specific glyco-questions they have prior to the course and we will try to discuss them during the course. Objectives: Understand glycan nomenclature and biosynthesis to aid mass spectrometry data interpretation. Know what analytical method to choose for you specific glycomics experiment. Learn how to interpret MS1 and MS2 data of glycans and glycopeptides. Know what software to use to aid glyco(proteo)mics MS data processing. 2053

Summary Do you have data files that you would like to accumulate over time into an organized, accessible format and then visualize different aspects of the combined data in an interactive, web-based dashboard? If so, this course is for you! Reproducibility is an important principle for making data analysis trustworthy and reliable. Automation enables users to scale their data analysis steps. The R programming language is one of many tools that can help users automate data analysis workflows while adopting best practices in reproducibility, but there are several packages to choose from when developing these skills. In this short course we will introduce a combination of workflows, packages, and tools that help learners set up data analysis projects, develop pipelines for extracting and storing data, and then develop interactive visualizations to gain understanding from the data. First, we will explain how to fully utilize the RStudio integrated development environment with Projects and how the renv package ensures that code consistently produces the same output no matter where or when it is run. Next, we will cover iterative file parsing and demonstrate how this can be linked to lightweight relational databases such as SQLite and DuckDB to build a pipeline for repetitive data loading over time. In the last portion of the course, we will discuss the Quarto scientific publishing system and related visualization tools such as the flexdashboard package. This short course will be interactive, with frequent short exercises to reinforce new concepts. Familiarity with the R programming language, either from an introductory course or self-learning, is highly recommended. Finally, concepts in this short course overlap material taught in previous intermediate R courses at MSACL, but here we will focus putting together the tools to develop reproducible, automated dashboards for visualization of laboratory data and provide updates to include some of the latest developments in the R ecosystem.

Course Schedule Segment 1 : Monday 13:30 - 17:30 (4 h) Segment 2 : Tuesday 08:00 - 12:00 (4 h) Total Contact Hours: 8.00 ------------ Objectives (1) Advantages for using DBS and other microsampling techniques in clinical and metabolomics research, discovery, and applications, (2) Strategies for maximizing analytical success with the mass spectrometer and DBS with examples of existing methods and successful applications. (3) Understand the application of global metabolomics and targeted metabolomics to disease diagnostics. Summary DBS have been used for nearly 60 years in a clinical and research environment specifically in rare disease screening of newborns or health monitoring and treatment to restore a more “normal” metabolism. Although clinical chemistry workflows are still dominated by liquid blood or plasma and immunoassay platforms, they are not necessarily suitable for microsample collection as demonstrated in the choice for newborn screening (200-300 µL) versus 1-10 mL for a venous blood draw. Furthermore, a dried microsample offers better protection from infectious disease during sample handling, is less expensive to ship in the mail, may stabilize some molecules from degradation of active enzyme, light or heat, and has reduce storage requirements during and after sampling. Perhaps the biggest advantage that is now recognized in the “post” pandemic world is remote patient sampling in an ever-expanding telemedicine environment. This course will describe the advantages of filter paper for mass spec workflows in areas of sample cleanup, extraction, manipulation as well as examples of successful analysis. We will provide examples of existing method in use in clinical analysis. As important are its advantages, we will discuss limitations from the lack of precision of classic Guthrie cards because of volume uncertainties to the problems of some mass spectrometry analysis of molecules like proteins. Finally we will correlate these issues with the ever expanding area of metabolomics, how research might benefit from small microsamples and remote sample collection especially on diseases that are rare in a patient that might be a continent away.

Objectives The objective of the workshop is to identify and overcome potential roadblocks preventing mass spectrometry-guided surgery to become routinely used in the clinical interventional world. The workshop will focus on the side-by-side comparison of existing technology and clinical needs, as also on the embedding of the technology into existing healthcare settings and regulatory aspects. The workshop is envisioned to outline the strategy for the clinical translation of these technologies. Summary The need for in-situ, real-time tissue identification has been dramatically increasing with the development and deployment of robotic and other high-precision surgical approaches. While surgical mass spectrometry techniques have been continuously developed, published and demonstrated in human surgical environment, none of these approaches have reached regulatory approval and routine application in surgery. We are planning to use the meeting to understand where the roadblocks are and how we can get around them to deliver the technology for patients and healthcare professionals equally needing it. The workshop is envisioned to map out the current technology landscape and identify the strengths and weaknesses of each solution together with their respective low-hanging fruit applications as the first main topic. This mapping exercise will be followed by discussing the embedding of the approach both into existing oncology and clinical diagnostic systems. The approach is expected to change how interventional cancer care (and potentially a few other treatments) is delivered, hence it is of utmost importance to understand this aspect from the point of view of pathologists, oncologists and medical imaging professionals. Furthermore, the technology will also be the forerunner of a universal, mass spectrometry-based diagnostic system, bringing LC-MS and MS imaging experts to the table. Beyond the embedding of the technology, we are also keen to discuss the regulatory and health economic aspects of the approach in the third part of the workshop. Syllabus/Topics Surgical mass spectrometry methods – strengths, weaknesses, applications and future perspectives Embedding of technology into healthcare systems.

Financial Disclosures (past 24 months as of Feb 12, 2024) : none Finnur Eiriksson, PhD ArticMass Financial Disclosures (past 24 months as of Feb 13, 2024) : none Objectives The objective of the workshop is to provide an introduction into design of experiments (DoE) for clinical application with special focus on optimization of MS-based clinical assays. The workshop is focused on practical implementation of DoE and will demonstrate how method development of sample preparation and UPLC-MS/MS method for quantification of clinical biomarkers can become much more efficient by utilizing DoE. Summary Design of experiments (DoE) is an efficient tool for development and optimization of UPLC-MS/MS platform for quantification of biomarkers in complex biological matrices. The UPLC-MS/MS platform is composed of several processes which involve many experimental factors that need to be simultaneously optimized to obtain a true maximum sensitivity with adequate resolution at minimum retention time. DoE offers a practical approach for performing experiments in accordance with a predefined plan, modelling by empirical functions, and graphical visualization. Basic concept of DoE will be presented with emphasis on practical implementation of DoE which includes the three main stages, screening, optimization, and robustness testing. To demonstrate the cost-effective benefit of DoE, which allows the effect of variables to be assessed with only a fraction of the experiments that would be required by changing one-separate-factor-at-time (COST) approach, two case studies will be presented. The first case is optimization of sample preparation in bottom-up targeted protein LC-MS workflow using DoE. The second case is an optimization of a UPLC-MS/MS assay for clinical diagnostic and therapeutic drug monitoring of patients with adenine phosphoribosyltransferase (APRT) deficiency, which is an inborn error of purine metabolism. A polynomial model which corresponds to the objective of the case study is specified and an experimental design that supports the selected model is generated. Significant factors were studied via central composite design and related to responses utilizing partial least square (PLS)-regression. Both cases showed that DoE is an excellent tool for optimization of sample preparation for biological samples and UPLC-MS/MS quantification method for clinical biomarkers. A significant reduction of sample preparation time was achieved with increased yields for selected peptides and a reliable UPLC-MS/MS assay for simultaneous quantification of urinary 2,8-dihydroxyadenine (DHA) and adenine was optimized efficiently with DoE.

Financial Disclosures (past 24 months as of Feb 13, 2024) : none Objective Attendees will learn the basic principles of ion mobility, benefits and challenges to routine implementation in the clinical lab, method development, and current applications. Summary Ion mobility-mass spectrometry (IM-MS) has become a cornerstone of biomedical analysis, with applications ranging from isomeric small molecule differentiation to the study of protein structure. Despite its advantages, IM-MS has yet to see routine implementation in the clinical lab due to challenges in quantitation, limited universal standards, data processing software, and reproducibility across different IM techniques/vendor platforms. This workshop will introduce common IM techniques and their operating principles, expanding upon the benefits of incorporating IM into conventional LC-MS/MS workflows and discussing its challenges. A discussion of method design and development will focus on how users might go about integrating IM into their existing (or new) assays. Finally, an overview of current applications (including metabolomics, lipidomics, and proteomics examples) will be provided. Objective 1: Understand the basic operating principles of IMS and the differences between the different techniques (e.g., drift tube, traveling wave, FAIMS/DMS, etc.) Objective 2: Recognize the benefits and limitations to incorporating IMS into conventional LC-MS/MS workflows in the clinic Objective 3: Become familiar with method design and development and current/future applications Syllabus Basic Operating Conditions of IMS: Electric field application, experimental conditions (temperature, pressure, gas composition) Different IMS techniques: Drift tube/traveling wave, field asymmetric/differential mobility, emerging techniques (i.e., TIMS, SLIM, cIMS, etc.) Applications: Current examples from metabolomics, lipidomics, and proteomics 2079

Objectives Recognize the role of laboratory developed tests (LDTs) in patient care Describe the current regulatory landscape of LDTs Define the VALID act and discuss its potential implications to the practice of laboratory medicine and patient care Summary Laboratory Developed Tests (LDTs) play a critical role in patient care. They are developed by expert laboratorians to bridge gaps between patient needs and available FDA-approved assays. LDTs are used to help diagnose and manage treatment for a variety of health conditions. These tests undergo extensive validation prior to implementation and, within the United States, are federally regulated by CLIA. The proposed Verifying Accurate Leading-edge IVCT Development Act of 2022 (“VALID Act”) includes additional regulation of LDTs by the FDA. If passed, the VALID Act would limit LDT access and the ability to provide timely laboratory testing to providers and patients, resulting in significant care gaps. This interactive workshop will provide an overview on what LDTs are, how they are validated and the current regulatory framework, highlighting papers published in the recent JMSACL special issue – Laboratory Developed Tests: Regulation, Assay Development, and Impact on Patient Care. We’ll also provide an overview on the status and potential implications of the VALID act. In the second half of the workshop, the audience will have a chance to share their opinions, questions, and concerns in a flipped classroom Q & A. 2080

Bendt, PhD Singapore Lipidomics Incubator (SLING), National University of Singapore Anne K Bendt studied Biology focusing on marine biotechnology (Greifswald University, Germany), followed by a PhD in Biochemistry (Cologne University, Germany) employing proteomics and transcriptomics. Driven by her fascination for infectious diseases, she joined the National University of Singapore (NUS) in 2004 to develop lipidomics tools for tuberculosis studies. She is now a Principal Investigator at the Life Sciences Institute, NUS, focussing on translation of mass spec technologies into clinical applications, and serving as the Deputy Director of the Singapore Lipidomics Incubator (SLING) taking care of operations and commercialization. Financial Disclosures (past 24 months as of Feb 13, 2024) : none Bo Burla, PhD Sling @ National University of Singapore I studied biology at the University of Zurich, Switzerland, and made my PhD in Molecular Plant Physiology in the lab of Prof. Enrico Martinoia, focusing on ABC transporters and comparative molecular phylogenetics. Subsequently, I became as researcher at the University Hospital of Zurich, where I was involved in establishing an LC/MS-based assay for the peptide hormone hepcidin and in projects studying Fabry Disease mechanisms. Biological processes, bioanalysis, clinical applications and the use of informatics to improve workflows have been my constant research interests. With this background I am now working as a senior researcher at the Singapore Lipidomics Incubator (SLING), heading our new data team that is focusing on developing workflows and software pipelines for the analytical data processing, QA/AC and exploration of the diverse lipidomics datasets generated by our lab. Financial Disclosures (past 24 months) : Not reported Objectives It is the objective of the workshop to provide an introduction into pre-analytical considerations for clinical application of MS-based analytics, with a special focus on lipids. However, these considerations are in many cases independent of specific analytes of interest and can hence be applied for polar metabolites as well as proteins. The workshop is focused on main hurdles to be considered when performing clinical research using LC-MS based determination of lipids namely: (I) pre-analytical sample handling, (II) frequent generation of patient samples as well as (III) overall cohort and study design. Summary Lipids are involved in a broad spectrum of functionalities in the organism and implicated in a variety of physiological and pathological processes. Changes in lipid levels are promising biomarkers for early diagnosis, prognosis of disease progression, or guidance for selecting promising therapeutic approaches. However, biomarker discovery in the field of lipidomics is a very challenging process since lipids require specific procedures regarding sampling (including selection of sample type and collection procedures, storage conditions and number of freeze-thaw cycles), sample preparation and analysis for reliable determination. As especially pre-analytical sample handling is a critical step for the reliable analysis of the lipidome, a close cooperation with the clinicians is necessary. This ensures following a highly standardized protocol for venous blood sampling to avoid several pre-analytical pitfalls potentially changing the lipid profile ex vivo. As collecting venous blood samples is very laborious for patients as well as clinicians, other ways for a more frequent sample collection are necessary. Therefore, capillary blood sampling using microsampling devices is an auspicious way to complement the strategy of analyzing venous blood-based samples taken in the clinics. Besides considering the right sampling strategy, the structured recording of sampling details and subject metadata, the overall planning of the study and also the cohorts to be included is of high relevance. All mentioned points have to be considered before starting a clinical research project applying lipidomics to generate high quality data making biomarker discovery possible. 2078

Objective The objective of this workshop is to walk attendees through the process of acquiring/installing an instrument, developing their first assay, validating the assay as a laboratory developed test, and then ensuring adequate performance once live. This will be done using the presenters experience implementing a liquid chromatography tandem mass spectrometry (LC-MS/MS) assay to quantify buprenorphine in human urine. At the end of the workshop, attendees should be able to: Justify the acquisition of an LC-MS/MS for clinical use Explain the major steps involved in developing a small molecule LC-MS/MS assay List the required elements for clinical validation of a small molecule LC-MS/MS assay Propose the steps necessary to ensure accurate results once live on a validated LC-MS/MS method Summary The continuing expansion of mass spectrometry into the clinical laboratory involves both expanding what testing can and should be done by mass spectrometry as well as expanding the number of labs implementing and utilizing existing/established assays. Unfortunately, too often the barrier of entry into mass spectrometry can be quite high. This workshop is designed to help walk attendees through the process of acquiring/installing an instrument, developing their first assay, validating the assay as a laboratory developed test, and then ensuring adequate performance once live (post-implementation monitoring). In particular, attendees will be given an overview of how these steps were done when the presenter setup and implemented a liquid chromatography tandem mass spectrometry (LC-MS/MS) assay to quantify buprenorphine in human urine in a College of American Pathologists (CAP) accredited laboratory. Special attention will be given resources that are available to assist labs undertaking the development and validation of clinical LC-MS/MS assays, resources such as published papers and CLSI guidelines. Practical factors such as sourcing consumables and necessary operating procedures will also be included. While the focus will be on implementing this specific assay, the goal is to share general best practices that were used that can be applicable to other assays.

Sponsored by: MICHAEL S. BEREMAN AWARD LECTURE 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)–associated proteins. The validated clinical assay provides insight into a patient’s cholesterol efflux capacity (the ability of HDL cholesterol to transport cholesterol away from the artery wall). The assay helps assess the patient’s risk for developing coronary artery disease and, ultimately, cardiovascular death. The assay is also a component in several clinical studies to further assess its utility. Furthermore, the research framework upon which this assay was designed continues to yield new insights into other pathologies, including non-alcoholic fatty liver disease (NAFLD), metabolic syndrome, and diabetes. In this presentation I will summarize our efforts, our successes, and lessons learned on the road from basic research to clinical deployment.

Financial Disclosures (past 24 months as of Dec 15, 2023) : none The Award Medal (100% metal) On the Award. Underlying precision medicine is the concept that an individual’s Omic signature (including the proteome) will provide a physician with clinically actionable diagnosis and a subsequent mechanistic therapeutic route. This requires i) having an array of mechanistic therapies for each disease and ii) a means to diagnosis (identify) which therapy (or combination) will be appropriate for a particular person. Proteomics has played a role in discovery and defining potential mechanistic routes, but it is now time to move into implementation. This will, we hope, drive democratize of precision medicine.

Sunrise Tai Chi / Qigong Activity @ Ferrantes (10th Floor @ Marriott) Tai Chi and Qigong (pronounced chee-gong) explore the underlying internal practices and approach to fitness training beyond merely moving the body. Ideal for stress reduction this experience involves the interpenetration of mind and body during movement; meaning it can’t just be the mind, or just the body separately. Qigong exercise includes opening energy centers, joints, and tendons. This is achieved in part through abdominal breathing to calm the mind and in turn relax the body in movement. During the relaxation phase you will learn to activate and sense energy kinesthetically in “felt” terms through simple moving practices. Practice session includes Healing Sounds which function in discharging heat and toxins trapped within the fascia around the internal organs. Qigong exercises together with Tai Chi aim to produce a mental and physical sense of balance, centeredness, and harmony. What to wear: One principle of Tai Chi and Qigong is relaxed, unrestricted movement, therefore casual loose-fitting clothing is recommended. Avoid tight fitting clothing. Skin breathes, body moves freely with more mobility. Remove any belts during practice. Footwear: Flat soled shoes preferable to feel balanced and rooted or connected to the floor, as opposed to high arched athletic shoes or raised heels. Shoes off OK as long as you aren’t subject to easily slipping or sliding. 2083

Financial Disclosures (past 24 months) : Not reported 1. Is There a Better Way to Plan and Perform Experiments? Introduction to Experimental Design Margrét Thorsteinsdóttir & Finnur Eiriksson Experimental design (DOE) is a technique that allows to be more efficient in planning, conducting and interpreting results of experiments. In Analytical Chemistry, DOE can be used during method development and optimization, troubleshooting performance and method evaluation. The DOE technique is also very helpful for identifying critical parameters, which have the most significant effect on performance of the methods, products, processes, or systems. The participants will learn why DOE is better than performing experiments by changing one variable at a time, learn about cause-and-effect relationships and interactions between factors. The participants will be introduced to several types of DOE, will learn some of the principles and guidelines for planning experiments. 2. Do Identical Instruments Produce Comparable Patient Results? A Stumbling Block of Harmonizing LC-MS/MS Assays in Clinical Laboratories Joyce Liao Clinical mass spectrometry laboratories usually validate individual assays on more than one instrument for continuous operation. Instrument comparison is a requirement of the College of American Pathologists and should be monitored at least twice a year to ensure comparability of results. Although the same style of liquid chromatography-tandem mass spectrometry system is preferred to minimize the variations between instruments, labs will inevitably encounter bias between two or more identical LC-MS/MS systems. Even in the absence of bias, the same instrument model with two different serial numbers may require different instrument settings to obtain similar sensitivity and specificity. In this roundtable session, we will review several comparison data sets from the same extractions injected and analyzed on two LC-MS/MS systems of the same make and model. We will discuss the potential factors, including mass spectrometer hardware (probe type and cleanness) and software settings (gradients, transitions, cone voltages, and collision energies) that could bias patient results and how to establish quality assurance policies to ensure adequate data review and accurate resulting. Examples of challenges we have faced and approaches we have found useful will be presented as a starting point for discussion. 3. Challenges and Possible Solutions on Direct Metabolome Profiling for Clinical Applications Liang Li Metabolomics is mainly used for disease biomarker discovery with an objective of translating newly discovered metabolite biomarkers into clinical applications. On the other hand, direct metabolome profiling of human biofluids may be used for monitoring health status of individuals on a population scale. However, there are a number of challenges in realizing this goal. This roundtable discussion will focus on exchanging views on several key areas of technical development that are needed to bring large-scale metabolome profiling to clinical settings. These include sample type, sample handling, analytical platforms, data processing, clinical metabolome informatics, cost and scale, etc. 4. Thyroid Function Testing Interference and How Mass Spectrometry Can Help: Interactive Case Studies Adam McShane Thyroid disease affects approximately 20 million Americans, and can lead to a multitude of symptoms. These are often grouped into 2 categories: hyperthyroidism (e.g., anxiety, weight loss, and sleep loss) and hypothyroidism (e.g. fatigue, weight gain, and forgetfulness). Clinicians rely heavily on biochemical assessment of the thyroid for accurate diagnosis to ensure prompt treatment. Routine thyroid function tests utilize immunoassays for their availability, speed, and automation. However, this testing suffers from a variety of interferences which can delay diagnosis or worse lead to miss diagnosis. Liquid chromatography-mass spectrometry (LC-MS) is a much more specific platform than immunoassays that can be utilized in the investigation of potential inferences. This session will utilize real-life, interactive cases to exemplify common thyroid function testing interferences, investigatory considerations, and how LC-MS can be utilized. 5.

Financial Disclosures (past 24 months) : Not reported The human genome project is recognized as being one of the most successful big science projects in modern history. One of the primary motivational underpinnings to undertake the HGP was to better understand what made us human and healthy - and how to use this code to improve the human condition by better understanding disease and potential treatment. While the frontiers of our knowledge expanded dramatically, we also uncovered profound biological complexity that we could not understand. This led to the current frontier in the measurement science of molecular phenomics, to catalog the broad-scale changes in the molecular inventory in cells, tissues, and biological fluids at a specific biological state, or in response to exposures and lifestyle choices. In phenomics, we seek to characterize the comprehensive molecular basis of biology (including DNA, RNA, proteins, lipids, carbohydrates, metabolites, and all of their nuances), in both space (e.g. at a cell, tissue, and organismal level) and time (e.g. healthy versus disease state). This places enormous demands on measurement technologies (including minimal sample preparation, fast measurements, high concentration dynamic range, low limits of detection, and high selectivity) and computational approaches to organize the millions of potential species present in vanishingly small spatial coordinates. The interplay between phenomic datasets and bioinformatics forms the nexus of translating phenomics data into actionable information and understanding. Advances in computational biology rely heavily on the experimental capacity to make omics measurements, i.e. integrated proteomics, metabolomics, lipidomics, glycomics, among many others. Ion mobility-mass spectrometry (IM-MS) provides rapid (ms) gas-phase electrophoretic separations on the basis of molecular structure and is well suited for integration with rapid (us) mass spectrometry detection techniques. This report will describe the fundamental strategies for IM separations and recent advances in IM-MS integrated omics measurement strategies in the analyses of complex biological samples of interest in systems, synthetic, and chemical biology. New advances in artificial intelligence and machine learning based on developments in internet commerce and astronomy will also be described to approach biological queries from an unbiased and untargeted perspective and to quickly mine these massive datasets. These techniques will be highlighted through selected examples ranging from clinical applications of targeted panels, to the creation of microfluidic human-organs-on-chip to replace animal testing in drug development workflows, to probing the outcomes of fast genetic editing experiments (using CRISPR) in the optimization of synthetic biology for fine and commodity chemical production to potential advances in clinical measurements. While enormous challenges remain, the promise is immense – comprehensive diagnostics and predictive capabilities for health and medicine of importance to society and beyond.

Advancing Neuroscience Research via Novel Application of Ion Mobility Mass Spectrometry (IM-MS) @ Steinbeck Ballroom Lingjun Li, PhD School of Pharmacy and Department of Chemistry, University of Wisconsin - Madison Lingjun Li is a Vilas Distinguished Achievement Professor and the Charles Melbourne Johnson Distinguished Chair Professor of Pharmaceutical Sciences and Chemistry at the University of Wisconsin-Madison (UW-Madison). Dr. Li received her B.E. degree in Environmental Analytical Chemistry from Beijing University of Technology, China and her Ph.D. degree in Analytical Chemistry/Biomolecular Chemistry from the University of Illinois at Urbana-Champaign (UIUC). She did three-way postdoctoral research at the Pacific Northwest National Laboratory, Brandeis University, and UIUC before joining the faculty at UW-Madison in December 2002. Her research interests are in analytical neurochemistry, neuroproteomics and biological mass spectrometry. Dr. Li published more than 300 papers and has given over 200 invited talks. She was the recipient of the ASMS Research Award, NSF CAREER Award, Sloan Fellowship, PittCon Achievement Award, and ASMS Biemann Medal, and was named one of the Top 50 most influential women in the analytical sciences and featured in the 2019 and 2021 Top 100 Power List by the Analytical Scientist. Dr. Li is currently an Associate Editor for the Journal of the American Society for Mass Spectrometry (JASMS) and served on the Board of Directors for the US HUPO. Financial Disclosures (past 24 months) : Not reported Naturally occurring D-amino acid substitution, also known as amino acid D-isomerization, has been observed in many disease-associated peptides and proteins, including amyloid beta (Aβ), one of the putative biomarkers and drug targets for Alzheimer’s disease. Aβ is of significant interest due to the prevalence of post-translational D-isomerization in AD brain samples. While many prior reports have described technical advancements associated with the chiral discrimination and separation of D-amino acid containing peptides, there remains a dearth of tools capable of targeting Aβ42 stereochemistry. Ion mobility-mass spectrometry (IM-MS) has increasingly become an important alternative for the chiral separation of Aβ stereoisomers. IM-MS offers high analytical speed, low sample consumption and the ability to resolve small structural differences in peptide analytes, driven by recent technological advancements in IM-MS. In this talk, I will present a multi-dimensional IM-MS-based structural analysis strategy to facilitate the study of the chiral effects on monomer structure, oligomeric propensity, and receptor binding for Aβ peptides. Furthermore, analytical strategies to enhance peptide epimer differentiation and for site-specific localization of D-amino acid containing peptides will be presented. Finally, I will discuss our recent efforts in developing a high-resolution ion mobility-enabled sn-position resolved lipidomics strategy for probing phospholipid dysregulation in the brain of a mouse model for Alzheimer’s disease.

Differential Ion Mobility Spectrometry: Understanding the Chemistry in the Mass Spectrometer and How That Affects What Is Detected @ Steinbeck Ballroom Gary Glish, PhD University of North Carolina Professor Gary L. Glish earned his Ph.D. from Purdue University under the guidance of Graham Cooks. He spent 12 years as a staff scientist and group leader at Oak Ridge National Laboratory during which time he designed and built the first QTOF instrument and his group was the first to interface ESI to a quadrupole ion trap mass spectrometer. He left Oak Ridge to take his current position as a faculty member in the Department of Chemistry at the University of North Carolina. His group there focused a lot on the fundamentals and development of applications for quadrupole ion traps. More recently the lab has been involved in the development of differential ion mobility spectrometry and development of ionization techniques for real-time analysis of aerosols. He was an associate editor for the Journal of the American Society for Mass Spectrometry for 17 years and has served as VP for Arrangements, VP for Programs, and President of the American Society for Mass Spectrometry. Financial Disclosures (past 24 months) : Not reported Differential Ion Mobility Spectrometry (DIMS) is a powerful tool that can help improve targeted detection of analytes using mass spectrometry (MS). DIMS has a number of advantages over more conventional drift type ion mobility techniques, but currently lacks the ability to determine collisional cross-sections. Some of the advantages of DIMS are: it is readily compatible with any type of mass analyzer; it is more orthogonal to MS because the separation is not based just on cross-section; and gas phase chemistry can be used to dramatically affect separation of analytes that are isomeric/isobaric and even have the same cross-section. A very under-appreciated aspect of DIMS is its ability to provide insight into the ionization chemistry and how that chemistry can significantly distort the resulting mass spectrum. This presentation will provide an overview of DIMS, examples of improvement of targeted analysis using DIMS with and without gas phase chemistry, and examples of how DIMS can provide understanding of chemistry occurring in the mass spectrometry experiment that can lead to inaccurate conclusions.

Heather Stieglitz, PhD, DABCC The Ohio State University Wexner Medical Center Dr. Stieglitz is currently an Assistant Professor at The Ohio State University Wexner Medical center and Co-Director of Clinical Chemistry and Toxicology. She received her PhD from Emory University and completed a postdoctoral fellowship in Clinical Chemistry at the University of North Carolina before joining Ohio State. She is board certified in Clinical Chemistry by the American Board of Clinical Chemistry. Her interests are in mass spectrometry-based clinical toxicology testing in adults and newborns. Financial Disclosures (past 24 months) : Not reported Confirmatory urine drug testing by liquid chromatography tandem mass spectrometry (LC-MS/MS) remains a corner stone of clinical mass spectrometry testing. This testing offers significant financial and patient care advantages and thus represents an excellent opportunity for new labs looking to establish or expand their LC-MS/MS testing. A clinical laboratory aiming to setup such testing will be faced with what can seem like an overwhelming number of options and decisions, especially if the laboratory is new or has limited experience with LC-MS/MS testing. This interest group discussion aims to help labs navigate these complex decisions by highlighting some approaches used by three clinical chemists who oversee toxicology testing at three medical centers. Topics that will be discussed include 1. choosing what drug classes and analytes (parent drug, metabolites, etc) to include, 2. whether to detect conjugated or unconjugated drugs, and 3. determining appropriate measuring and reportable intervals. This interactive session will begin with an introduction of the topic using case examples of how each speaker approached the issue followed by an open discussion with the audience on the advantages and limitations of different approaches. 2076

Discussion : Use of Reference Materials for Calibration and Validation in Clinical Mass Spectrometry Applications @ Colton Johanna Camara, PhD NIST Johanna began her employment at NIST as an NRC Postdoctoral Associate. Her activities have encompassed a wide variety of areas, including: MALDI-ToF mass spectrometry of bacteria, molecular cloning of stable-isotope labeled proteins for mass spectral internal standards, and the quantification of small organic molecules in pharmaceuticals, foods, and biological SRMs with liquid chromatography-mass spectrometry. She has participated in the Summer Undergraduate Research Fellowship program at NIST as an application reviewer and research mentor. Johanna is also the Clinical SRM Program Coordinator, the Quality Manager for the Organic Chemical Metrology Group, and the Deputy Quality Manager for the Chemical Sciences Division. Financial Disclosures (past 24 months) : Not reported Reference materials (RMs), including certified reference materials (CRMs), are provided by the National Institute of Standards and Technology (NIST) and other RM producers to support global clinical measurement standardization. These materials are available in various forms, including neat powders, solutions, and clinical matrices. The intended RM uses include calibration and validation, depending on the material. Calibration with RMs may provide traceability to higher-order references when incorporated into specific measurement schemes. The choice of which RM to use and how to incorporate it into a measurement system depends on laboratory goals. This roundtable is designed to discuss RM production, availability, and options for incorporating RMs into clinical laboratory measurement applications. Many RMs are ideally suited for mass spectrometry-based measurement procedures. Many matrix matched RMs (blood serum, plasma, urine) are value assigned based on mass spectrometry-based Reference Measurement Procedures (RMPs). These RMPs typically separate and quantify individual metabolites, epimers, or other chemical variations of clinically relevant measurands that are not necessarily separated and detected by other laboratory techniques, such as immunoassays or microbiological assays. RM users may also need to propagate the measurement uncertainty of RM or other calibrator values to measurement results. NIST provides a publicly available online application ABACUS (Apps for Bayesian Analysis of Chemical quantities Using Shiny) intended as a tool for users to use all data from their experiments to calculate results with rigorous estimates of measurement uncertainty. 2019

Discussion : Clinical LC-MS/MS User Training is Lacking : Moving Towards Training and Certification @ Stevenson 1 Judy Stone, MT (ASCP), PhD, DABCC Clinical Chemist (retired) Judy Stone, MT (ASCP), PhD, DABCC has worked with LC-MS in diagnostic laboratories since 1999. Her clinical practice involved small molecule method development, instrument to instrument and instrument to LIS interfacing, LC-MS automation, monitoring quality of LC-MS methods in production and staff training for clinical LC-MSMS. She served as faculty chair for the 2009 AACC online certificate program “Using Mass Spectrometry in the Clinical Laboratory”, as a scientific committee member for the MSACL Practical Training track, and was editor-in-chief for the AACC Clinical Laboratory News quarterly feature series on Clinical LC-MS. She enjoys documenting and presenting esoteric as well as absurdly common LC-MS problems in creative ways in order to help trainees learn troubleshooting (and avoid repeating her mistakes). Financial Disclosures (past 24 months as of Feb 15, 2024) : none Currently, there exist no formal training programs or licensure prerequisites for medical laboratory quantitative LC-MS/MS method development scientists or technologists. Although rudimentary LC-MS/MS theory may be part of Medical Laboratory Scientist (MLS) or Medical Laboratory Technologist (MLT) programs, quantitative LC-MS/MS method development is highly complex and typically not included. Lab Directors who are authorized to approve LDT methods are not necessarily trained in the details of technical quantitative LC-MS/MS validation. We see a need for training and certification. This round table aims to get input and discuss a way forward and discussion topics will include: (1) Training options Traveling Trainer Laboratory Participant Training Sites (2) Certification how can we move forward? What certification body is best? This session is geared towards lab directors, lab scientists, and lab technologists. The goal is to get input from the community about what is needed and how the needs can be addressed. 2020

Sunrise Tai Chi / Qigong Activity @ Ferrantes (10th Floor @ Marriott) Tai Chi and Qigong (pronounced chee-gong) explore the underlying internal practices and approach to fitness training beyond merely moving the body. Ideal for stress reduction this experience involves the interpenetration of mind and body during movement; meaning it can’t just be the mind, or just the body separately. Qigong exercise includes opening energy centers, joints, and tendons. This is achieved in part through abdominal breathing to calm the mind and in turn relax the body in movement. During the relaxation phase you will learn to activate and sense energy kinesthetically in “felt” terms through simple moving practices. Practice session includes Healing Sounds which function in discharging heat and toxins trapped within the fascia around the internal organs. Qigong exercises together with Tai Chi aim to produce a mental and physical sense of balance, centeredness, and harmony. What to wear: One principle of Tai Chi and Qigong is relaxed, unrestricted movement, therefore casual loose-fitting clothing is recommended. Avoid tight fitting clothing. Skin breathes, body moves freely with more mobility. Remove any belts during practice. Footwear: Flat soled shoes preferable to feel balanced and rooted or connected to the floor, as opposed to high arched athletic shoes or raised heels. Shoes off OK as long as you aren’t subject to easily slipping or sliding. 2084

IVDR : The Regulation Environment in the EU Michael Vogeser As of May 2022, the In Vitro Diagnostics Regulation (IVDR) regulates items (such as calibration and QC materials) manufactured and used in individual medical laboratories in the European Union. The interpretation of the IVDR is still controversial on several points. 5. Testing in Dried Spots, Microcollection Devices and Self-Collection: What’s trending? Jessica Colon-Franco The COVID-19 pandemic led to an unprecedented increase of digital health visits. This practice is seen as an effective strategy to manage patients with chronic diseases, although the long term sustainability and impact beyond the pandemic is still evolving. Decentralized sample collection for laboratory testing is projected as a major cornerstone to sustain telemedicine efforts, and could increase remote access to testing and outcomes. Although promising, the literature regarding self-collection and outcomes remains scarce. Moreover, only a few laboratories offer testing in these devices likely due to the technical limitations of these devices, and considerably increased technical and regulatory needs. The purpose of this roundtable is to foster a discussion about the potential clinical applications of testing in dried spots and other self-collection devices, some of the existing literature and technology, clinical practice trends, and foreseeable needs and gaps. The format will consist of presenting brief case studies/vignettes related to testing in these devices, followed by guided and open discussions. 2022
