This study investigates the diagnostic practices for mucormycosis among 30 French University Hospital mycology laboratories, in 2024. All laboratories perform both direct examination and culture, with fluorescent brighteners being the most commonly used method for direct examination. While 77 % of the participating laboratories routinely identify Mucorales to the species level, with 70 % having adopted Mucorales-specific quantitative PCR, primarily for the diagnosis of invasive fungal infections.

Background: Objective structured clinical examinations (OSCEs) are extensively used in many medical schools worldwide with the stated objective to assess students' clinical skills acquired during internships. The objective of the present study was to assess the factors associated with success in university summative OSCEs, especially the impact of previous hospital internships in corresponding disciplines and supervision during internships.

Methods: This was a cross-sectional study assessing the results in the summative OSCEs of 4th year medical students during the 2021-2022 academic year in a French medical school.

Article Synopsis
  • Candida auris is a growing threat to healthcare facilities globally, necessitating systematic screening for patients from high-risk areas to prevent widespread outbreaks.
  • A study analyzing responses from 36 French mycologists found that only 30.6% were aware of any systematic screening protocols for C. auris in their hospitals.
  • Most post-admission screening focused on specific body sites, but only a small percentage utilized specialized testing methods, highlighting the need for increased awareness and better practices among healthcare professionals regarding systematic screening for this pathogen.

Background: Meyerozyma guilliermondii is a yeast species responsible for invasive fungal infections. It has high minimum inhibitory concentrations (MICs) to echinocandins, the first-line treatment of candidemia. In this context, azole antifungal agents are frequently used.

Background: Data on the risk of invasive fungal infections (IFI) with ibrutinib treatment are scarce.

Objectives: This study aimed to determine IFI incidence and risk factors in ibrutinib-treated patients in real-life settings.

Methods: We constituted a cohort of ibrutinib incident users in the French National Healthcare Database.

Pulmonary mold infections are life-threatening diseases with high morbi-mortalities. Treatment is based on systemic antifungal agents belonging to the families of polyenes (amphotericin B) and triazoles. Despite this treatment, mortality remains high and the doses of systemic antifungals cannot be increased as they often lead to toxicity.

Few antifungal agents are currently available for the treatment of fungal infections. Antimicrobial peptides (AMPs), which are natural molecules involved in the innate immune response of many organisms, represent a promising research method because of their broad killing activity. The aim of this study was to assess the activity of a frog AMP, [K]temporin-SHa, against some species of yeasts and moulds, and to further explore its activity against .

The aim of this study was to evaluate the effect of the combination of amphotericin B (AmB) and various non-ionic surfactants on the anti- activity of AmB, the toxicity of the combination on eukaryotic cells and the modification of AmB aggregation states. Checkerboards were performed on five genera of (12 strains) using several combinations of different surfactants and AmB. These data were analyzed by an E model.

Article Synopsis
  • Chronic granulomatous disease (CGD) is an inherited immunodeficiency caused by faulty NADPH in leukocytes, leading to frequent infections and inflammation.
  • The condition is mainly due to mutations in the CYBB gene, predominantly affecting males, but females can also show symptoms based on their X-inactivation patterns.
  • A case study highlights a 67-year-old asymptomatic female carrier diagnosed with CGD after developing a rare fungal skin infection, revealing the importance of monitoring carriers for late onset diseases.

Unlabelled: Alveolar macrophages (AM) are the first-line lung defense against Mucorales in pulmonary mucormycosis. Since corticosteroid use is a known risk factor for mucormycosis, the aim of this study was to describe the role of corticosteroids on AM capacities to control Lichtheimia corymbifera spore growth using a new ex vivo model. An in vivo mouse model was developed to determine the acetate cortisone dose able to trigger pulmonary invasive infection.

Candida auris is an emerging species responsible for life-threatening infections. Its ability to be resistant to most systemic antifungal classes and its capacity to persist in a hospital environment have led to health concerns. Currently, data about environmental reservoirs are limited but remain essential in control of C.

Mucormycosis are life-threatening fungal infections especially affecting immunocompromised or diabetic patients. Despite treatment, mortality remains high (from 32 to 70% according to organ involvement). This review provides an update on mucormycosis management.

CNOT1 is a member of the CCR4-NOT complex, which is a master regulator, orchestrating gene expression, RNA deadenylation, and protein ubiquitination. We report on 39 individuals with heterozygous de novo CNOT1 variants, including missense, splice site, and nonsense variants, who present with a clinical spectrum of intellectual disability, motor delay, speech delay, seizures, hypotonia, and behavioral problems. To link CNOT1 dysfunction to the neurodevelopmental phenotype observed, we generated variant-specific Drosophila models, which showed learning and memory defects upon CNOT1 knockdown.

A female 66 year-old patient, not immunocompromised, was admitted in ICU for severe influenza complicated by severe acute respiratory distress syndrome (ARDS) leading to extra-corporeal membrane oxygenation (ECMO). During ICU hospitalization, she developed a disseminated invasive aspergillosis with cerebral access and coronary occlusion which lead to cardiac arrest. Despite a successful revascularization procedure, the patient died of refractory shock.

A survey of mycology laboratories for antifungal susceptibility testing (AFST) was undertaken in France in 2018, to better understand the difference in practices between the participating centers and to identify the difficulties they may encounter as well as eventual gaps with published standards and guidelines. The survey captured information from 45 mycology laboratories in France on how they perform AFST (number of strains tested, preferred method, technical and quality aspects, interpretation of the MIC values, reading and interpretation difficulties). Results indicated that 86% of respondents used Etest as AFST method, with a combination of one to seven antifungal agents tested.
