    Communicable E13 - The Wild West of publishing today: predatory journals and how to deal with them

    The market of predatory publishing is as lucrative as it is unethical. Predatory journals are disguised as legitimate entities, and prey on both early-career academics and the naïve. In this episode of Communicable, hosts Angela Huttner and Marc Bonten are joined by Editors-in-chief Ursula Hofer (Lancet Infect Dis) and Leonard Leibovici (CMI) to discuss the various schemes of the ‘Wild West’ of publishing, and how to avoid them.    This episode was edited by Kathryn Hostettler and peer-reviewed by Dr. Özlem Türkmen Recen, Izmir Public Health Laboratory, Izmir, Türkiye.   Literature    Research4Life https://www.research4life.org/    Benedictus R et al.

    Communicable E12 - The Nightmare Series, part 3: How to deal with vancomycin-resistant enterococci

    Enterococci are commensal microbes, part of the healthy microflora populating the human gut. But they are also opportunistic pathogens and notorious nosocomial agents with intrinsic traits that promote their pathogenesis and make them difficult to kill. In the third instalment of the Nightmare Series, hosts Angela Huttner and Thomas Tängdén are joined by enterococcal experts Kimberly Kline (University of Geneva) and Louis Rice (Brown University) to discuss what make vancomycin-resistant enterococci, or VRE, such a clinical nightmare. Enterococcus faecalis and Enterococcus faecium are the focus.   This episode was edited by Kathryn Hostettler and peer-reviewed by Dr. Nunzia Esposito of the University of Naples Federico II, Naples, Italy.   Literature    Stellfox ME et al.

    Communicable E11 - Nightmare series, part 2: How to deal with carbapenemase producers

    Carbapenemase producers are a nightmare for clinicians. Not only are they resistant to carbapenems, a last resort β-lactam antibiotic, they are notorious for developing multidrug and pandrug resistances resulting in limited to no treatment options.  In this episode of Communicable, hosts Angela Huttner and Thomas Tängdén sit down with Dr. David Paterson (National University of Singapore) and Dr. Souha Kanj (American University of Beirut Medical Center, Lebanon), two ID physicians from regions where carbapenem-resistant Enterobacteriaceae or CRE, and carbapenem-resistant Acinetobacter are widespread.  The episode begins with the history and emergence of CRE and reviews current epidemiology, diagnosis (including the Ambler classification of β-lactamases) and treatment options. Lessons and insights from personal experiences are shared to reflect the current clinical challenges caused by carbapenem-resistant bacteria and the importance of infection prevention and control measures to mitigate further spread.   This episode was edited by Kathryn Hostettler and peer-reviewed by Dr. Filippo Medioli of Policlinico di Modena, Italy.

    Communicable E10 - Pipeline update: new antibiotics & other antimicrobials that you might actually use

    On the verge of a post-antibiotic reality, there is an urgent clinical need for new antibiotics. Luckily, new candidates are in the pipeline and older agents are getting a second breath of life through combination therapy.    In this episode of Communicable, host Erin McCreary invites Dr. Markus Zeitlinger of the University of Vienna (Austria) and scientific expert for the European Medicines Agency (EMA) and Dr. Michael Dudley, president and CEO of Qpex Biopharma, to discuss antimicrobials in the clinical development pipeline.  Together they unpack how the WHO curate the priority list of pathogens and how companies adapt such lists into their antimicrobial development business plans. They also discuss the unique challenges and complexities of developing antibiotics, from return on investments and defining the ‘novelty’ of an agent to the conundrum of balancing post-market approval and antimicrobial stewardship. Beta-lactamase inhibitors and oral carbapenems in the pipeline targeting ‘the big three’ (Enterobacterales, Pseudomonas and Acinetobacter) are the primary focus.   This episode was edited by Kathryn Hostettler and peer-reviewed by Dr. Benjamin Berinson of the Medical Centre Hamburg-Eppendorf (UKE), Germany.

  5. Communicable E9 - Avian flu: an update

    9 DE SET.

    Communicable E9 - Avian flu: an update

    The current H5N1 avian flu outbreak in poultry and dairy cows in the US has raised the alarm on bird flu and its transmission risk across species. At present, the virus has infected 100 million birds across 48 states and 196 dairy herds across 14 states. Luckily, the H5N1 avian flu, which is very lethal in birds, does not transmit easily into humans nor does it generally cause severe and systemic symptoms when humans are infected. Still, workers most exposed to these infected animals are testing positive with 14 human cases reported so far since 2022.  In this Communicable episode, hosts Angela and Nav are joined by avian flu expert Ron Fouchier (Erasmus MC Rotterdam, Netherlands) to discuss the most recent developments of the outbreak in the US and the potential risks H5N1 virus poses to humans. Understanding of the virus from its first reported outbreak in Hong Kong in 1997 to its global prevalence today is reviewed. While H5N1 bird flu does not pose as a global human health concern at present, unchecked practices in the dairy, meat, and agricultural industry sectors, in which workers are exposed to the virus, threaten to change the status quo. Learn why the threat is even more paramount in fall when human influenza or seasonal flu is widespread, and to what extent the government should also be involved in prevention and containment measures before it becomes, in Ron’s words, another “missed opportunity.”           This episode was edited by Kathryn Hostettler and peer-reviewed by Dr. Simon Galmiche of the Institut Pasteur, Université Paris Cité, Paris, France.

    Communicable E8 - The Nightmare Series, part 1: How to deal with Candida auris

    Only known to us since 2008, Candida auris is an emerging fungal pathogen spreading quickly around the world; alarmingly, it is most commonly found in healthcare settings. C. auris sets itself apart from other Candida species with its unique tolerance to high saline and temperature environments and propensity to develop antifungal resistances that promote its survival in hospitals and healthcare facilities.  Hosts Emily McDonald and Navaneeth Narayanan are joined by fungal experts Dr. Jeffrey Rybak (St. Jude, Memphis TN) and Dr. Graham Snyder (UPMC, Pittsburgh PA) on their quest to better understand C. auris infections, the clinical challenges and knowledge gaps in C. auris research and discuss measures for prevention and containment on the levels of both the patient and the institution.  The recent emergence of C. auris as a multidrug-resistant nosocomial pathogen and its global prevalence has raised more questions than answers. Why now? Why healthcare facilities? Does climate change play a role? Are humans to blame? Tune in to find out what the experts have to say on these questions, and stay to learn about the current therapies available, what is in the antifungal pipeline and how to approach treatment from a stewardship standpoint.

    Communicable E7 - Melioidosis goes global

    Once considered endemic only to tropical and subtropical climates such as Southeast Asia and northern Australia, melioidosis is expanding to non-endemic areas such as the southern US. Climate change is impacting infectious diseases, melioidosis being no exception. Now is the time to inform and prepare: as this Communicable episode’s title indicates, melioidosis is going global. Join hosts Angela Huttner and Josh Davis on their in-depth exploration of melioidosis with invited experts Dr. Ella Meumann and Prof. Bart Currie from Royal Darwin Hospital, Darwin, Australia. Topics range from melioidosis discovery, clinical presentation, diagnostic approaches and host risk factors to the disease’s expanding endemicity. Melioidosis is an infectious disease caused by the sapronotic agent Burkholderia pseudomallei and contracted by both people and animals through direct contact with contaminated soil, air or waters. Current burden estimates of 169’000 cases and 89’000 deaths per year are thought to be grossly underreported due to limited access to laboratory diagnostics and lack of clinical awareness. Experts call for melioidosis to be recognized as a neglected tropical disease in order to give this disease the urgent attention and resources it deserves.
