    Good news and bad news in the fight against AMR

    “Humans are locked in an arms race with microbes, but scientists are pursuing diverse approaches to keep one step ahead or slow down the competition.” This is the first sentence of the news feature ‘Five ways science is tackling the antibiotic resistance crisis’ published in Nature this week.

  • Staphylococcus aureus bacteremia and acute kidney injury

    Staphylococcus aureus bacteremia and acute kidney injury

    Ever wondered what the risk is of Acute Kidney Injury (AKI) in patients with Staphylococcus Aureus Bacteremia (SAB)? I did not, and I didn’t know.

  • The gastropulmonary route of infection: fact or fiction?

    The gastropulmonary route of infection: fact or fiction?

    In the 1990s – when I started my PhD – this was a relevant and intensely debated question. Now, almost 35 years later, we finally have the answer.

  • Control yourself: the self-controlled case series

    Control yourself: the self-controlled case series

    Does influenza increase the risk of acute myocardial infarction (AMI)? Do bivalent mRNA COVID-19 vaccines cause acute ischemic stroke? Relevant questions, but difficult to answer. Incidences of both outcomes are low, precluding an answer from randomised trials (in case of vaccination) and analyses from observational studies will be flawed by…

  • Solving the small crappy trial problem

    Solving the small crappy trial problem

    Randomised controlled trials (RCTs) yield the strongest evidence to inform medical practice. Each year, more than 40,000 new RCTs are registered, and some have estimated that they cost more than 80 billion US dollars. Yet RCTs are remarkably inefficient.

  • How to change RCT-based “definitive” practice 

    How to change RCT-based “definitive” practice 

    Randomised controlled trials (RCT) provide the highest level of evidence. But what to do if a disease changes? Only a new RCT can provide sufficient evidence to change the associated RCT-based practice.

  • COVID-19: An outbreak of books

    COVID-19: An outbreak of books

    Twenty-nine years ago, Bob Weinstein told me that “every outbreak is in fact three outbreaks: spread of a pathogen, followed by an outbreak of meetings, followed by an outbreak of publications.” A pandemic adds a next level: an outbreak of books.

  • How deadly is antibiotic resistance?

    How deadly is antibiotic resistance?

    How can we quantify the attribution of antibiotic resistance to detrimental patient outcome? Some believe that in 2050, 10 million people will die every year because of antibiotic resistance! But is antibiotic resistance always the cause of death? And if so, how can we explain detrimental outcomes of infections treated…

  • Nebulized amikacin and VAP prevention (part 2): the art of circular reasoning

    Nebulized amikacin and VAP prevention (part 2): the art of circular reasoning

    Three months ago, a French investigator-initiated, multicenter, double-blind, randomized, placebo-controlled study reported that nebulized amikacin reduced the occurrence of VAP. Positive cultures of endotracheal aspirates were part of (the few) diagnostic criteria for VAP. My response was that “the possibility of artificial sterilization of microbiological cultures through nebulized amikacin is…
