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.

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

BONUS FUN ACTIVITY:
We are certain there is a very catchy title for this series. "The Real World: Clinical Mass Spec" and "Josh vs The World" didn't make the cut. If you think you have the perfect titles, let us know (Twitter handle @MSACL). Your ideas could be featured right here on MSACL Connect!

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’s “per se” (by definition presumed to be impaired) laws.

There was no relationship between whole blood concentrations of THC and performance on a driving simulator. Smoking active drug produced a significant (p< 0.05) decrement in driving performance that lasted for 2-3 hours. The sensitivity and specificity of THC and metabolites as recent markers of marijuana varied according to the selected cutpoint.

Recognition of driving impairment will likely continue to depend on both officer observations and toxicology results.

I graduated in analytical chemistry from the faculty of chemistry at Shahid Beheshti University (Tehran,Iran).For my Master's thesis I was working on the Optimization of solid phase microextraction and electromembrane extraction techniques to measure certain pollutants and drugs. During my studies,I was also awarded medals and honorary diplomas from international and national competitions and expositions because of my inventions. In June 2017, I started my Glysign PhD project, conducting research at Genos Ltd., Zagreb, Croatia, and the Leiden University Medical Centre in Leiden, the Netherlands. My research is geared towards the quantification of serum protein glycosylation for patient stratification in early-onset and other diabetes types.

# Originally scheduled to be presented at MSACL 2020 US. Moved from August 10 make-up session due to timing conflict.

Introduction

Type 2 diabetes mellitus (T2D) represents a major public health challenge. The total plasma N-glycome (TPNG) reflects the levels and glycosylation of major plasma glycoproteins, among which are immunoglobulins, acute-phase proteins and apolipoproteins. Although associations of TPNG with T2D have been recently reported by us and others, data on the association between TPNG and T2D complications are scarce. Here, we applied our new ultrahigh-resolution MS method to assess associations of TPNG with T2D complications.

Methods

We determined the TPNG in a subsample of the Hoorn Diabetes Care System cohort (n = 1519 T2D cases and 192 nondiabetic controls from the New Hoorn study cohort) using our Fourier-transform ion cyclotron resonance MS method. Blood plasma samples were randomized over 21 96-well plates, together with technical replicates. Prior to MS analysis, N-glycans were released using PNGase F. For stabilization and linkage differentiation, sialic acids were derivatized. Released glycans were purified and spotted using an automated liquid handling platform. In total, 68 individual glycan compositions were quantified after total-area normalization and summarized into derived traits representing structural features. By applying logistic regression models, we tested for associations of TPNG with case-control status and micro- or macrovascular complications, such as nephropathy, retinopathy, or cardiovascular disease (cross-sectional). T2D complications were also assessed prospectively by Cox regression. Models were adjusted for age, sex, and T2D risk factors. The outputs were meta-analyzed together with our MALDI-TOF-MS data from the independent cohort DiaGene (1815 T2D cases and 836 controls) which we obtained and described previously.

Results

The recently developed method using MALDI-FTICR-MS improved resolution, mass accuracy, dynamic range and the signal-to-noise ratio, especially for larger glycans, in comparison to our previous MALDI-TOF workflow. The relative standard deviation over the 68 detected glycan species was on average 6.6%, based on the relative intensities from 93 technical replicates of pooled plasma, representing total method repeatability.

We found significant associations of all major glycosylation traits, i.e. sialylation, fucosylation, galactosylation, bisection, and glycan complexity with T2D in the meta-analyses of both cross-sectional and prospective data. For example, the bisection and galactosylation of immunoglobulin-related glycans were associated with macrovascular complications and nephropathy. We aim to confirm these results in the near future on protein-specific level, by isolating IgG prior to released-glycan analysis.

Conclusions

Our new method improved the detection of several glycan species, thus providing possible new insights into the association between TPNG and T2D. Our results will be taken forward to improve personalized approaches in T2D and related complications in the future.

*This talk was originally scheduled to be presented at MSACL 2020 US. It is expected to be about 35-45 minutes, not including Q&A.

Background: The detection and quantitation of siderophores in urine represents an innovative early indication of pathogenic microorganisms in a host [1]. In this presentation, we document why the general application of siderophores in invasive infectious diagnostics will soon represent the same clinical breakthrough as ribosomal protein typing ten years ago. In addition to handling co-infections or polymicrobial frenemies, with mass spectrometry, we can monitor the antimicrobial drug metabolism [2].

Methods: A database of 700 microbial siderophores was used for screening a patient’s status with invasive infections caused by Aspergillus fumigatus, Pseudomonas aeruginosa, and zygomycetes. Human urine samples were examined by liquid chromatography and Fourier-transform ion cyclotron resonance (FTICR) mass spectrometer [3]. The biomarkers were quantified against matrix-matched standards, and our in-house tool called CycloBranch (https://ms.biomed.cas.cz/cyclobranch) was used for compound dereplication [4].

Results: For the diagnosis of aspergillosis, we used an array of ferri-triacetylfusarinine C (TAFC)/ferri-ferricrocine (FC)/gliotoxin (GTX) in a cohort of 28 patients (14 positive and 14 negative controls). LOD for TAFC in human urine was 0.1 ng/mL. The maximum experienced concentration was 1.7 ug/mL. In the working dataset of critically ill, mostly non-neutropenic humans, the TAFC/FC/GTX sensitivity in urine was 93% compared to standard GM in serum (36%). The kinetic profiles upon antimycotic treatment showed a quick drop in siderophore production in vivo. In the same cohort, ferri-pyoverdines and pyochelin were detected as urinal biomarkers in the patients with Pseudomonas aeruginosa. The LOD for Fe-PVD in urine was 10 ng/mL. In serum samples, the LOD and LOQs were 1 and 5 ng/mL, respectively. In the seminar I will also show the co-infecting frenemies studied in animal models of bacterial [5] or fungal infections [6].

Conclusion: Urinal samples are analytically attractive due to less chemical background compared to serum and clinically interesting due to non-invasive applications. Optimized sample preparation could soon move siderophore analysis from FTICR equipment to standard MALDI-Biotyper-type labs.

# 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®5600 using a positive-ion mode TOF-MS survey scan with IDA-triggered collection of high resolution product ion spectra (20 dependent scans). Data was screened for fentanyl, norfentanyl, 13 literature-reported synthetic opioids, and compounds reported/suspected to cause false positives with fentanyl immunoassays.

Results

158 emergency department patient samples screened positive via EMIT fentanyl immunoassay (7.44% of all ED samples screened for drugs of abuse). These samples were analyzed via LC-HRMS and analysis was targeted for 15 synthetic opioids and commonly prescribed or over-the-counter pharmaceuticals with chemical structures similar to that of fentanyl. 6.9% of samples were found to be positive for both fentanyl and acetyl fentanyl. Additionally, risperidone, its metabolite 9-hydroxyrisperidone (paliperidone), and loperamide with its metabolite desmethylloperamide were discovered as sources of false positive for fentanyl screens.

Conclusion

This data reveals the non-trivial prevalence of fentanyl in the ED patient population being screened for drugs of abuse. In many of the cases, fentanyl was not suspected or discovered as exposure agent prior to more comprehensive testing or patient discharge. The identification of acetyl fentanyl along with fentanyl via HRMS analysis can hint to a changing trend in provenance of illicitly manufactured fentanyl. Finally, HRMS is a valuable tool to identify compounds responsible for reoccurring false positives that can inform better patient care and offer a more accurate picture of the continually evolving opioid epidemic.

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.

Assistant Professor at the Maastricht MultiModal Molecular Imaging (M4I) institute, I have more than 8 years of experience in the MSI imaging fields and had the opportunity to gain insights on different aspects, including instrumental development, sample preparation and quantification. Since I have earned my PhD at the School of Pharmaceutical Sciences (University of Geneva), I am now devoted to demonstrate how MSI can be employed to improve the accuracy of cancer diagnostics. I am strongly motivated by the translational aspect between the development of innovative instrumentation and direct application to clinical research – with a special focus on intraoperative mass spectrometry – and by the close collaboration with the Surgeons and Pathologists of the Maastricht University Medical Center + (MUMC+), and with the RWTH Aachen in Germany.

One of the predominant challenges in systems-wide analyses and molecular phenomics is the broad-scale characterization of the molecular inventory in cells, tissues, and biological fluids. Advances in computational systems biology rely heavily on the experimental capacity to make omics measurements, i.e. integrated metabolomics, proteomics, lipidomics, glycomics, etc., accompanied with fast minimal sample preparation, fast measurements, high concentration dynamic range, low limits of detection, and high selectivity. This confluence of figures-of-merit place demanding challenges on analytical platforms for such analyses. 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 recent advances in IM-MS integrated omics measurement strategies in the analyses of complex biological samples of interest in systems, synthetic, and chemical biology in clinical chemistry applications. New advances in bioinformatics and biostatistics will also be described to approach biological queries from an unbiased and untargeted perspective and to quickly mine the massive datasets gathered to provide targeted and actionable information.

This is a VIRTUAL 2-Day Course with 8 total contact hours. CE to be provided.

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.

Course material will be provided electronically.

Prof. Hewison is currently Professor of Molecular Endocrinology within the Institute of Metabolism and Systems Research (IMSR) at the University of Birmingham, UK, having worked from 2005 – 2014 at the University of California Los Angeles. Prof. Hewison’s main research interest is vitamin D and its importance to human health. He has published over 230 research papers on classical (skeletal) and non-classical (extra-skeletal) actions of vitamin D. Prof. Hewison’s group is at the forefront of research linking vitamin D and the immune system, with implications for a wide range of clinical disorders including infectious, inflammatory and autoimmune disease. 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).

Online Format

This is a virtual version of the short course that has been presented at MSACL. This online course includes 2.5-5 hours of live lecture each day for four days. Using Zoom (live online lectures, breakout rooms for interactive sessions) and Google Classroom (forms and job aids for download, on demand short lecture videos) provides additional opportunities for interactive and self-paced learning, both during the four-day course and beyond.

The resources posted in Google Classroom will be available to registrants for at least 3 months. We can’t give you hands-on experience with cutting PEEK tubing or changing check valves in an online course. But the potential with a virtual platform for networking and updates with actionable information to help you with your daily LC-MS/MS clinical practice seems almost limitless.

Course Content Description

Is your laboratory under pressure to purchase an LC-tandem MS or is the ROI you wrote last year haunting you now? This short course is designed for attendees implementing quantitative LC-tandem MS for patient testing who have laboratory medicine experience but no mass spectrometry training - CLS bench analysts, supervisors, R&D scientists, and laboratory directors. Theoretical concepts necessary for a robust implementation of clinical mass spectrometry will be presented – but the emphasis is on practical recommendations for:

1. LC-MS/MS system purchasing
2. site preparation and installation
3. defining preliminary MSMS and LC parameters for your first method
4. selecting and optimizing sample preparation for your first method
5. choosing internal standards, solvents, and water, making reagents and calibrators
6. adjusting sample preparation, LC and MSMS parameters to achieve the desired assay performance
7. establishing data analysis & batch review criteria
8. pre-validation stress testing and method validation
9. preventative maintenance and troubleshooting
10. maintaining quality in production.

Our goal is to present just enough theory so you can report high quality results, while opening a window to the depth and complexity of clinical mass spectrometry such that your appetite is whetted to learn more. The IFCC Committee for Distance Learning published a curriculum guideline for post-graduate trainees in laboratory medicine in 2017. This course includes all of the IFCC mass spectrometry curriculum listed in the “Principles of Analysis X-MS” section, except that we focus only on triple quadrupole mass spectrometry; metabolomics, proteomics and inborn errors of metabolism are not discussed. See also this reference by one of the team of short course instructors “Liquid chromatography-mass spectrometry education for clinical laboratory scientists”.

Previous exposure to the principles of clinical method validation, either didactic or practical, is assumed. A post-course online exam will be available, with a certificate of completion for those who take and pass the exam within the examination window of two weeks after the four day short course.

Dr. Xin Yan received her Ph.D. in Chemistry from Purdue University in 2015 under the supervision of Professor R. Graham Cooks. After graduation, she did her postdoctoral research with Professor Richard N. Zare at Stanford University.
Dr. Xin Yan joined the chemistry department, Texas A&M University as an assistant professor in the summer of 2018. Her research centers around the development and application of droplet chemistry in lipid/metabolite analysis, reaction acceleration, and new synthetic methods.

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.

R. Graham Cooks is the Henry Bohn Hass Distinguished Professor in the Department of Chemistry at Purdue University. He has served as major professor to 140 PhD students. Dr. Cooks’ was a pioneer in the conception and implementation of tandem mass spectrometry (MS/MS) and of desorption ionization, especially molecular secondary ionization mass spectrometry (SIMS). In 2015 his lab performed exploratory analysis of small molecules in cerebrospinal fluid from which the MRM-profiling method emerged. His work also includes the development of miniature portable mass spectrometers using ambient ionization and application of this combination to problems of trace chemical analysis at point-of-care. His interests in the fundamentals of ion chemistry focus on chiral analysis based on the kinetics of cluster ion fragmentation. His group also studies collisions of ions at surfaces for new methods of molecular surface tailoring and analysis, and nanomaterials preparation by soft-landing of ions and charged droplets. Dr. Cooks also launched new method of preparative mass spectrometry based on accelerated reactions in microdroplets. Dr. Cooks has been recognized with the Mass Spectrometry and the Analytical Chemistry awards of the American Chemical Society, the Robert Boyle Medal and the Centennial Prize of the Royal Society of Chemistry, and the Camille & Henry Dreyfus Prize in the Chemical Sciences. He is an elected fellow of the American Academy of Arts and Sciences, the Academy of Inventors and the U.S. National Academy of Sciences.

Nicolás is a third year PhD student under the supervision of Prof. Graham Cooks at Purdue University. He earned two bachelor’s degrees, one in Chemistry (cum laude, 2017) and one in Industrial Engineering (summa cum laude, 2018), from the Universidad de los Andes (Bogotá, Colombia). Since joining the Cooks’ group his research has focused on several applications of ambient ionization mass spectrometry for the rapid and simple analysis of complex mixtures, particularly oriented towards forensics and high throughput bioanalysis. Recently he was awarded the 2020-2021 Charles H. Viol Memorial fellowship for his work during his first years as doctoral student.

We describe an automated high throughput screening system which is used to acquire mass spectra at a rate of 6,000 samples/hour using desorption electrospray ionization (DESI). The system has been used to screen organic reactions and select optimum conditions for scaled-up drug synthesis, to analyze biological fluids without sample workup, to examine tissue library arrays and to perform label-free quantitative measurements of enzyme kinetics. Extensions of the instrumentation to collection of small amounts of synthesis products for in situ bioassays are also described.

Overview:

Having completed your first steps into the wonderful world of data analysis with R, would you like to go further? You’ve learned the basics of R, so now it’s time to put that knowledge to work and tackle some interesting clinical applications. Along the way you will also be introduced to even more of capabilities of R and the tools developed by the amazing R community.

The 4-DAY ONLINE ONLY virtual (via Zoom) short course will be split between lecture sessions, individual problem solving, and a highly interactive group-level data mining of real data sets. Like the introductory course, this class will maintain the “no student left behind policy”. Students will be given time to solve problems taken from real-life laboratory work and to do some more advanced analysis on large scale data sets. All attendees will need access to a laptop with both R language and R Studio interface installed. Students may use Windows, Mac OSX or Linux environments. Both R and R studio are free and open-source.

Students should be prepared to continue to expand their skill in programming – which, as you learned in the introductory course (Data Science 101) can be a little frustrating, but not as frustrating as not being able to get the computer to do what you want at all!
