| Communicable E63: Does oseltamivir harm critically ill patients? The REMAP-CAP results | 20 Sep 2026 | 01:03:09 | |
At the Critical Care Reviews meeting in Belfast in June this year, REMAP-CAP investigators presented results suggesting that oseltamivir may be harmful in critically ill patients with influenza, upending a long-standing clinical practice in intensive care [1]. In this fourth collaboration between SIDP’s Breakpoints and ESCMID’s Communicable podcasts, hosts Erin McCreary and Josh Davis are joined by Steve Webb (Monash University), senior REMAP-CAP investigator and 'godfather of adaptive trial design', and Steve Tong (University of Melbourne), esteemed clinical trialist and friend of both podcasts. Together, they walk through the trial domain’s design, outcomes and results, also highlighting how these findings demonstrate the importance and clinical impact of randomised clinical trials. At the time of this episode recording in August, the results discussed were available as a preprint version [1]. Resources

| Communicable E48: International Women's Day - are infections & AMR really different in women? | 08 Mar 2026 | 00:39:24 | |
Yesterday was International Women's Day. In light of that, Communicable prepared a special episode in which hosts Erin McCreary and Annie Joseph are joined by Esmita Charani (South Africa) and Annette Westgeest (Netherlands) for a discussion on gender- and sex-dependent patient-care disparities in the infectious diseases space. Together they review recent research findings that identified gender and sex as important determinants influencing patient outcomes and even decision making by prescribers. They also explore how societal and cultural norms may introduce further nuance and complexities. The panel remains optimistic in reaching equal healthcare for all, reflecting also on progressive steps such as increasing recognition by international organisations like the WHO, which published guidance on gender inequalities in national plans on AMR in 2024. This episode was peer reviewed by Casandra Bulescu at the Dr. Victor Babes Clinical Hospital of Infectious and Tropical Diseases in Bucharest, Romania. References

| Communicable E47: Drawing the line - the writing, reach, and limits of guidelines | 22 Feb 2026 | 01:00:09 | |
In this third collaboration between SIDP’s Breakpoints and ESCMID’s Communicable podcasts, hosts Erin McCreary and Angela Huttner invite two veteran authors of guidelines and guidances, Pranita Tamma (Philadelphia, USA) and Benedikt Huttner (WHO, Geneva, Switzerland) [1-3]. Together, they deconstruct the complex landscape of developing and implementing guidelines into digestible components: they discuss why different organizations develop guidelines and what need they hope to fulfil, the framework including the GRADE methodology under which guidelines are written, and major barriers in the uptake of guidelines. The conversation also details the distinction between guideline and guidance as well as the art and science behind formulating recommendations or suggestions, with a few anecdotal cases sprinkled in from the panel. This episode was edited by Kathryn Hostettler and Lacy Worden. It was peer reviewed for Breakpoints by Lacy Worden and for Communicable by Ljiljana Lukić of University Hospital for Infectious Diseases in Zagreb, Croatia. References

| Communicable E46: Steroids for pneumocystis pneumonia | 08 Feb 2026 | 00:55:14 | |
In this episode of Communicable, Navaneeth Narayanan and Josh Nosanchuk invite Virginie Lemiale and Elie Azoulay (Paris, France) as well as fellow editor Emily McDonald (Montreal, Canada)—this time as guest—to discuss adjunctive steroid therapy for pneumocystis pneumonia (PCP) in HIV-negative individuals. In 2025, Lemiale and Azoulay published results from their double-blind, randomised controlled trial investigating steroid treatment for severe Pneumocystis jirovecii pneumonia (PIC trial) in the Lancet Respiratory Medicine [1]. At first glance, one might dismiss the study’s clinical impact due the ‘negative' result of the primary outcome, mortality at 28 days, which just missed a statistically significant difference between groups. There was a clinical difference, however, and all other outcomes, including 90-day mortality, were significantly different between groups. Understanding how pivotal these results were to clinical practice, McDonald and colleagues sought to contextualise the results of the PIC trial through a Bayesian analysis in a follow-up publication [2]. While the discussion provides useful clinical commentary, it also helps both to demystify Bayesian analysis and to call attention to what might be lost with strict or overly concrete interpretations of traditional frequentist analyses.

| Communicable E42: Should doctors stay at X (Twitter) or leave it? | 14 Dec 2025 | 01:05:03 | |
During the COVID-19 pandemic with lockdown mandates and social distancing, doctors, researchers, and the public were able to find refuge and community online; for the infectious disease community, it was on the social media platform Twitter, and more specifically under the widely used hashtag, #IDTwitter. Under new ownership from 2022, however, Twitter’s name and brand changed to what we now know as X, and “the heyday of #IDTwitter is long since gone”. In this special episode of Communicable, Angela Huttner and Marc Bonten invite doctors and science communicators, Neil Stone (London, UK), Ilan Schwartz (Durham, USA), and Tara Smith (Kent, USA) to debate whether we should stay on X or leave it for alternatives. This episode is a follow-up from Stone and Schwartz’s commentary [1] and Smith’s response letter [2] addressing the same topic published in CMI Communications.

| Communicable E37: 'Peer review is broken' | 05 Oct 2025 | 01:07:02 | |
Contrary to popular belief, peer review has only recently become an integral step in scientific publishing. Currently seen by many as a badge of honour ensuring valid, innovative and honest research, peer review seems in reality to be increasingly thankless, exploitative, and sometimes invisible. How did we get here? In this episode of Communicable, Annie Joseph and Angela Huttner are joined by two experts, Melinda Baldwin (University of Maryland, USA) and Serge Horbach (Radboud University, Netherlands), to unpack and examine the role of peer review, why it is still essential, and how it fits within the greater editorial process. The conversation covers the history of peer review, contemporary formats including open review and the use of artificial intelligence, and thoughtful discussion on how to fix and rethink peer review.

| Communicable E34: WHO's Fungal Priority Pathogens List | 24 Aug 2025 | 00:50:24 | |
Fungal infections and disease have long been overlooked in terms of healthcare burden, with poor diagnostics and limited options for treatment and management. In 2022, the WHO published its first Fungal Priority Pathogens List as an effort to establish a global prioritised framework that addresses unmet research and development needs in fungal disease and antifungal resistance, as well as guides public health action [1]. In this episode of Communicable, Angela Huttner and Josh Nosanchuk invite Hatim Sati (WHO), the project lead in creating this list, and Dimitrios Kontoyiannis (MD Anderson Cancer Center, Houston, Texas), a clinician researcher studying fungal diagnostics and antifungal discovery, for a candid discussion on the making of and relevance of such a list. Apart from reviewing the fungal pathogens, the conversation also covers limitations of the list, what to expect for the next iteration, contextualising the list in one’s local region, and the impact the list has had already on research funding and public awareness.

| Communicable E33: Ethics in infectious diseases | 10 Aug 2025 | 00:36:51 | |
Ethics in the field of infectious disease can be a delicate interplay between treating the individual patient and protecting the collective health of a society. Sometimes these two mandates go hand in hand; at other times they can appear to be in conflict. In this episode of Communicable, Dr. Angela Huttner invites Drs. Zeb Jamrozik (Melbourne, Australia) and Beenish Syed (Karachi, Pakistan), two members of ESCMID’s Ethics Advisory Committee, to unpack different scenarios encountered in the field of infectious disease from an ethics standpoint: how one ethically allocates scarce resources like antimicrobials; whether there is ethical justification for coercive public-health measures like lockdowns; and whether the need to collect evidence to advance patient care could include other models besides opt-in informed consent.

| Communicable E32: Fluoroquinolones - to heal or harm? | 27 Jul 2025 | 00:55:56 | |
Fluoroquinolones (FQs) are valuable given their broad-spectrum activity against Gram-positive and Gram-negative bacteria and their high penetration into various tissues. Yet FQs have also caused concern, with some market withdrawals, important and sometimes long-lasting adverse drug events, and substantial collateral effects on the microbiota. In this episode of Communicable, hosts Emily McDonald and Thomas Tängdén invite Staffan Tevell (Karlstad, Sweden) and Bernadette Young (Oxford, UK) to weigh in on the pro-con debate of FQ use, especially for periprosthetic joint infections (PJIs), which can entail longer treatment durations. They review the standard of care for PJIs, including FQs in combination with rifampicin vs other antibiotic combinations, the impact of the OVIVA trial advocating for early oral switch strategies, the long list of rare but important side effects, and how best to preserve FQs for clinical indications that most need them.

| Communicable E31: Climate change and fungal spread | 13 Jul 2025 | 00:51:53 | |
The adaptability of fungi to warmer temperatures is an obvious consequence of climate change. Perhaps less obvious is the role climate change has played on fungal pathogens emerging as a global health concern. While humans are mostly protected from fungal infections by our immune system and body temperature, a warming global climate could subvert the status quo. Some fungi are already adapted to warmer temperatures and causing invasive acute infections in humans: Candidozyma auris, Cryptococcus neoformans, and Aspergillus fumigatus, to name a few. In this episode of Communicable, Angela Huttner and Josh Nosanchuk invite Arturo Casadevall, a Bloomberg Distinguished Professor at Johns Hopkins and this year’s recipient of ESCMID’s Excellence in Science Award, to discuss the world of fungi and their pathogenic potential in a warming world. Other topics include how to prepare for their emergence as a health threat, how fungi can be harnessed for applications that can benefit us, and ultimately answering the question Casadevall himself posed in the title of his recently published book, What if fungi win? This episode was edited by Kathryn Hostettler and peer reviewed by Robin Aerts of University Hospital Antwerp, Belgium.

| Communicable E30: WHO's first-ever guideline on meningitis | 29 Jun 2025 | 01:00:57 | |
Meningitis remains a major global health threat, with an estimated 2.5 million cases each year; of these, one in six results in death and one in five in long-term disabilities. Although meningitis “can strike anyone, anywhere in the world,” outbreaks disproportionately impact low- and middle-income countries, where diagnostic and treatment resources are limited. In efforts to address this, WHO launched its first-ever guideline on meningitis diagnosis and management in April this year. In this episode of Communicable, hosts Emily McDonald and Marc Bonten are joined by two experts directly involved in creating the guideline, Lorenzo Pezzoli and Nicolò Binello (WHO), as well as Jacob Bodilsen (Aalborg University), clinician-researcher and Chair of ESCMID’s Study Group for Infectious Diseases of the Brain (ESGIB). The guests offer a firsthand look behind the guideline’s development, review key recommendations for diagnosis and treatment - including the use of lumbar puncture, antibiotics, and chemoprophylaxis – and discuss how these fit into various clinical settings.

| Communicable E29: Bacterial vaginosis & male partners | 15 Jun 2025 | 00:59:33 | |
Bacterial vaginosis (BV) was long considered not to be a sexually transmitted infection (STI), and treatment was only for women to bear. That was the convention at least until Catriona Bradshaw and her team at the Melbourne Sexual Health Centre published their groundbreaking clinical trial results earlier this year, demonstrating that treating male partners of women with BV prevented recurrence in those women. In this episode of Communicable, hosts Angela Huttner and Annie Joseph welcome back Bradshaw to discuss her trial’s design, results, and clinical implications—with some guidelines already updated to include male partners in BV treatment regimens. The conversation also explores the complexities of BV diagnosis, the challenges of trial execution in general, and future research directions.

| Communicable E18: The Nightmare Series, part 4 - How to manage polio and rubella | 12 Jan 2025 | 00:59:47 | |
Rising anti-vaccine sentiment and dissemination of misinformation are threats to public health. In the US, calls to revoke certain public health mandates have been proposed by likely members of the incoming administration, among them vaccination against polio. The fourth instalment of the Nightmare Series is both a cautionary tale and an effort to preserve and share clinical expertise on how to diagnose and manage polio and rubella in a world where, until now, few doctors have had to face these illnesses in the clinical setting. Host Angela Huttner welcomes Professor Emeritus of Infectious Diseases Bernard Hirschel at the University of Geneva and Dr. Kerrigan McCarthy of the Centre for Vaccines and Immunology at South Africa’s National Institute for Communicable Diseases (NICD) for that discussion.
