Innovative strategies to conduct clinical trials under difficult circumstances were required. We will discuss these strategies with some people who created them! Objectives: • Understand the main challenges to conduct clinical trials in the middle of a pandemic both in the developed and developing world • Discuss strategies for patient recruitment and evaluation. • Deliberate on future strategies to study new therapies for emerging pathogens. Guests: • David Boulware, MD MPH. Professor of Medicine and Infectious Diseases, University of Minnesota. • Eduardo López-Medina, MD. Assistant Professor of Pediatrics at Universidad del Valle, and Director of Pediatric Infectious Diseases, Centro Medico Imbanaco, Cali Colombia.

  • Mythbusting in Susceptibility Testing (JCM ed.)

    25/06/2021 Duração: 36min

    Accurate antibiotic susceptibility testing, or AST, is a key tool in addressing the rise in antibiotic-resistant bacteria. But AST is one of the most complicated and rapidly changing areas in the clinical microbiology, and the resulting confusion can make it difficult for clinical laboratories to keep up with best practices. Dr. Romney Humphries joins to talk about controversies and myths about AST. This episode was recorded with a live, remote audience at the World Microbe Forum. It is brought to you by the Journal of Clinical Microbiology, available at jcm.asm.org and on twitter @JClinMicro. Visit asm.org/eic for links.

  • Staphylococcus argenteus: another coagulase positive Staphylococcus (JCM ed.)

    28/05/2021 Duração: 28min

    In addition to Staphylococcus aureus, there are a small number of other coagulase-positive staphylococci. We have become increasingly aware of these due to improvements in identification methods used in clinical laboratories. Staphylococcus argenteus is a coagulase-positive Staphylococcus that, until now, had mainly been detected in Australia, the Pacific Islands and Thailand. It was thought that the species might be geographically restricted, however a paper in the June issue of the Journal of Clinical Microbiology describes a large number of isolates collected from patients in North America. We’ll be talking to two of the authors of this paper. Guests: Dr. Julianne Kus, Dr. Audrey Schuetz

  • Reconciling Genotypic and Phenotypic Susceptibility Tests (JCM ed.)

    30/04/2021 Duração: 40min

    Our options for susceptibility testing have greatly increased in recent years. In addition to classical phenotypic susceptibility testing by disk diffusion and measurement of the minimum inhibitory concentration, genotypic tests are increasingly available. Genotypic tests range from tests for a single organism and one resistance gene to tests for 20 or more organisms and multiple resistance genes. But what should the clinical microbiologist do when the results of phenotypic and genotypic are in conflict? Welcome to Editors in Conversation. This episode is brought to you by the Journal of Clinical Microbiology, available at jcm.asm.org and on twitter @JClinMicro. I'm JCM Editor in Chief, Alex McAdam. This podcast is supported by the American Society for Microbiology, which publishes JCM. Guests: Dr. Patricia Simner, Dr. Jennifer Dien Bard Visit https://jcm.asm.org to read more

  • Gaps in Laboratory Diagnosis of Fungal Diseases (JCM ed.)

    02/04/2021 Duração: 46min

    The incidence of fungal infections is rising in immunocompromised people, and the morbidity and mortality of these infections are high. Recent threats include multi-drug resistant Candida auris, however antifungal resistance is rising in other species as well, such as Aspergillus fumigatus. But have advances in diagnostic testing kept up with the accelerating threats of fungal infections?

  • Pandemic Built Environment (mSystems ed.)

    29/03/2021 Duração: 33min

    During the pandemic researchers who focus on the microbiology of built environments suddenly found themselves at the center of attention. Understanding how SARS-CoV-2 may be spreading indoors became incredibly important to ensure we can operate indoors in a safe manner. We now know that SARS-CoV-2 transmits through the air in droplets and as particles, and this information has helped us to provide comprehensive advice on how people should manage the indoor environment. Last year my guests published a review in mSystems: 2019 Novel Coronavirus (COVID-19) Pandemic: Built Environment Considerations To Reduce Transmission. This is published with co-authors David A. Coil, Mark Fretz, and Jonathan A. Eisen. This paper was the most downloaded article for mSystems in 2020, and was in the top ten most downloaded articles across all ASM journals. This is maybe not surprising based on the topic covered. Guests: Leslie Dietz, Patrick Horve, Kevin Van Den Wymelenberg Links mentionoed: Microbes and social equity working

  • Optimizing Blood Cultures with Dr. Eric Ransom and Dr. Valeria Fabre (JCM ed.)

    05/03/2021 Duração: 43min

    Blood cultures for bacteria and yeast are among the most clinically important and high-volume tests performed by clinical microbiology labs. Because these cultures are so important to clinical care, we want to make sure that blood cultures are performed as quickly and accurately as possible, and that they are ordered, collected and utilized appropriately. We are going talk about two recent papers. The first is about diagnostic stewardship for improving utilization of blood cultures and the second is about reporting blood culture results more quickly. Guests: Maria Valeria Fabre, M.D., Eric Ransom, Ph.D. Some of the questions we’ll discuss include: • What steps can be taken to reduce the number of inappropriate blood cultures ordered in non-neutropenic adult patients? • Can the final results of blood cultures be reported earlier than the canonical 5 days?

  • Susceptibility testing for Staphylococci Other Than S. aureus (JCM ed.)

    12/02/2021 Duração: 38min

    Susceptibility testing for staphylococci other than S. aureus, or SOSA, has become increasingly complicated, as more laboratories use MALDI-TOF to routinely identify these bacteria to the species level. In particular, accurate identification of methicillin resistance has become more complex as the different species are distinguished by the accuracy of different susceptibility testing methods and breakpoints for interpreting MICs and zone sizes.  Some of the questions we’ll discuss include: What is the gold standard for detecting methicillin resistance in SOSA? How will the recommended breakpoints for detection of methicillin-resistant SOSA change? Why should we call these bacteria SOSA instead of coagulase-negative staphylococci? Guests: Dr. Romney Humphries, Dr. Lars Westblade Links mentioned: Evaluation of Surrogate Tests for the Presence of mecA-Mediated Methicillin Resistance in Staphylococcus capitis, Staphylococcus haemolyticus, Staphylococcus hominis, and Staphylococcus warneri The End of Coagulase-
