Editors in Conversation

There are a number of regulatory proposals under consideration which could have important effects on clinical microbiology labs, and clinical labs more generally. First, the VALID act would change how clinical tests are regulated with particularly important implications for laboratory-developed tests. Second, the Centers for Medicare and Medicaid Services has proposed changes to the educational requirements for lab directors under CLIA and additional changes that would increase the fees that clinical labs pay to CMS. If you have been waiting for someone to explain these changes and how they could affect your lab, you've come to the right podcast.

Infections caused by Mycobacterium abscessus appear to be increasing in frequency among the immunocompromised population and are challenging to treat. Antibiotic options in these cases are scarce, prolonged therapy is required and new options are needed. We will discuss this important topic with experts in the field.

• Define M. abscessus as an opportunistic pathoge
• The intrinsic phenotypic characteristics of M. abscessus, including resistance to common antimicrobials
• Treatment approaches and rationale for these strategies

• Kelly Dooley, MD. PhD, MPH. Professor of Medicine, Johns Hopkins University and Editor of AAC
• Charles L. Daley, MD, Professor and Chief of the Division of Mycobacterial and Respiratory Infections. National Jewish Health

The inoculum effect of antibiotic susceptibility testing is often discussed at playgrounds and infectious diseases conferences, but many of us don't really have a clear definition of what it is or a good understanding of its importance.

We'll be talking about the inoculum effect and susceptibility testing of Staphylococcus aureus with cefazolin.

Some of the questions we'll discuss are: • What exactly is the inoculum effect and how is it measured? • Does the inoculum effect have clinical significance? • How common is the inoculum effect with Staph aureus and cefazolin?

As July 26, the world has documented 19,188 cases of monkeypox, with 3,591 cases in the US alone, making the US the country with the most known infections amid the global outbreak. The WHO has declared monkeypox a public health emergency. Although this disease has been known for years, certain features suggest that we are facing a unique outbreak of monkeypox with the potential for worldwide spreading.

In this special podcast edition of Editors in Conversation we will discuss the diagnosis and treatment of monkeypox with experts in the field who have dealt with significant number of cases in the US.

Topics:

• The significance of the monkeypox outbreak • The approach for the diagnosis of monkeypox • The treatment approaches and prevention tools for monkeypox

This special episode is brought to you by Journal of Clinical Microbiology and Antimicrobial Agents and Chemotherapy journals.

Hosts: - Cesar A. Arias, Editor in Chief of AAC, - Dr. Elli Theel, Editor of JCM

This podcast is supported by the American Society for Microbiology, which publishes both JCM and AAC. Don't forget to check the latest issues of JCM and AAC with outstanding papers on microbial diagnostics, mechanisms of resistance, pharmacology of antimicrobial agents, epidemiology and clinical therapeutics, among others.

Joining us to discuss this important topic are:

• Jason Zucker, MD. Assistant Professor of Medicine at Columbia University Medical Center and Infectious Diseases physician at New York-Presbyterian / Columbia University Irving Medical Center • Benjamin Pinsky, MD, PhD, Associate Professor of Pathology and of Medicine (Infectious Diseases). Stanford University, palo Alto, CA. Medical Director of the Clinical Virology Laboratory for Stanford Health Care and the Stanford Children's Health.

Dr. Bobbi Pritt aka @parasitegal, creator of the blog Creepy Dreadful Wonderful Parasites, is a pathologist and clinical microbiologist with specialty interests in parasitic and vector-borne infections, and the pathology of infectious diseases. Dr. Pritt discusses her career and how she became an expert in clinical parasitology, her work internationally and how others can participate in global health work and how technology (digital pathology, AI, automation, etc.) will affect the lab and technicians in the future.

Infections caused by Stenotrophomonas maltophilia appear to be increasing in frequency among the immunocompromised population and are challenging to treat. Moreover, resistance to traditional drugs used against these organisms is now becoming more common. Antibiotic options in these circumstances are scarce and new options are needed. We discuss this important topic with experts in the field. Recorded live in Washington DC at ASM Microbe 2022.

Topics

• Stenotrophomas maltophilia as an opportunistic pathogen and • The intrinsic ability of Stenotrophomonas maltophilia to resist common antimicrobials • Common mechanisms of resistance in Pseudomonas aeruginosa • Debate on treatment approaches and rationale for these strategies.

Guests:

• Maria Fernanda Mojica PhD Senior Instructor, Case VA Center for Antimicrobial Resistance and Epidemiology. Case Western Reserve University
• Samuel Aitken, PharmD. Adjunct Clinical Professor of Pharmacy, University of Michigan.

We are just back from the Molecular Virology Workshop in West Palm Beach. This is a terrific meeting that is organized by the Pan-American Society for Clinical Virology or PASCV. The workshop immediately precedes the Clinical Virology Symposium that ASM organizes and many of us like to attend both. Today we'll be talking about some of the high points of the Molecular Virology Workshop, with two members of the organizing committee from PASCV.

• Dr. Erin Graf, Director, Clinical Microbiology at Mayo Clinic in Phoenix Arizona.
• Dr. Stephanie Mitchell, Director of Medical Affairs at Cepheid.

It is estimated that anywhere from 575,000 to 677,000 bloodstream infections occur annually in North America, with approximately 40,000 of those directly linked to patient mortality in the United States, making bloodstream infections the 11th most common cause of death in the US according to the Centers for Disease Control and Prevention. The detection of bloodstream infections and subsequent identification of the etiologic agent or agents is an essential role played by all clinical microbiology laboratories, day-in and day-out for routine patient care. So, today, we are going to dive into a recently published study in JCM, looking at organism-specific bloodstream infection prevalence rates and their individual mortality risks relative to patients with either negative blood cultures and in those for whom blood cultures were not ordered.

Guests: - Dr. Nick Daneman - senior author on the manuscript, is a Clinical Scientists in the Division of Infectious Diseases at Sunnybrook Health Sciences Centre at the University of Toronto, and a Adjunct Physician at Public Health Ontario. - Dr. Kevin Brown is a Scientist at Public Health Ontario and Assistant Professor at the University of Toronto

This episode is dedicated to the memory of the late George A. Jacoby, who was a pillar in the B-lactamase research community and a leader in the field of antimicrobial resistance. Assigning names to b-lactamase variants has been inconsistent and has led to confusion in the published literature. The common availability of whole genome sequencing has resulted in an exponential growth in the number of new b-lactamase genes. In November 2021 an international group of b-lactamase experts met virtually to develop a consensus for the way naturally-occurring b-lactamase genes should be named.

• The inconsistencies in B-lactamase nomenclature
• Guidelines for publication of new alleles and newly discovered B-lactamases
• Future needs of consensus among the b-lactamase community

• Patricia Bradford PhD., Antimicrobial Development Specialists LLC
• Karen Bush PhD, Professor of Practice, Biotechnology and Interim Director, Biotechnology Program, Indiana University.
• Robert Bonomo MD, Professor Case Western Reserve University, Director VA CARES Research Collaborative
