Abstract
Fungal infections can be challenging to diagnose in returning travellers due to their non-specific clinical manifestations and changing epidemiology. We present a case of progressive disseminated histoplasmosis in a returning traveller from Bangladesh. The patient had a progressive and prolonged respiratory illness necessitating mechanical ventilatory support. The clue to potential fungal aetiology was provided by serum fungal markers - 1-3-β-D-glucan and Aspergillus galactomannan. Diagnosis was eventually made using panfungal PCR on bronchioalveolar lavage fluid.

Abstract
Almost 380,000 new cases of oral cancer were reported worldwide in 2020. Oral squamous cell carcinoma (OSCC) accounts for 90% of all types of oral cancers. Emerging studies have shown association of Toll-like receptors (TLRs) in carcinogenesis. The present study aimed to investigate the expression levels and tissue localization of TRL1 to TRL10 and NF-κB between OSCC and healthy oral mucosa, as well as effect of Candida colonization in TRL expression in OSCC. Full thickness biopsies and microbial samples from 30 newly diagnosed primary OSCC patients and 26 health controls were collected. The expression of TLR1 to TLR10 and NF-κB was analyzed by immunohistochemistry. Microbial samples were collected from oral mucosa to detect Candida. OSCC epithelium showed lower staining intensity of TRL1, TRL2 TRL5, and TRL8 as compared to healthy controls. Similarly, staining intensity of TRL3, TRL4, TRL7, and TRL8 were significantly decreased in basement membrane (BM) zone. Likewise, OSCC endothelium showed lower staining intensity of TLR4, TLR7 and TLR8. Expression of NF-κB was significantly stronger in normal healthy tissue compared to OSCC sample. Positive correlation was found between the expression of NF-κB, TRL9 and TRL10 in basal layer of the infiltrative zone OSCC samples (P = 0.04 and P = 0.002, respectively). Significant increase in TRL4 was seen in BM zone of sample colonized with Candida (P = 0.01). According to the limited number of samples, our data indicates downregulation of TLRs and NF-κB in OSCC, and upregulation of TLR4 expression with presence of Candida.

Abstract
The objectives of this study were to assess Candida spp. distribution and antifungal resistance of candidaemia across Europe. Isolates were collected as part of the third ECMM Candida European multicentre observational study, conducted from 01 to 07-07-2018 to 31-03-2022. Each centre (maximum number/country determined by population size) included ∼10 consecutive cases. Isolates were referred to central laboratories and identified by morphology and MALDI-TOF, supplemented by ITS-sequencing when needed. EUCAST MICs were determined for five antifungals. fks sequencing was performed for echinocandin resistant isolates. The 399 isolates from 41 centres in 17 countries included C. albicans (47.1%), C. glabrata (22.3%), C. parapsilosis (15.0%), C. tropicalis (6.3%), C. dubliniensis and C. krusei (2.3% each) and other species (4.8%). Austria had the highest C. albicans proportion (77%), Czech Republic, France and UK the highest C. glabrata proportions (25-33%) while Italy and Turkey had the highest C. parapsilosis proportions (24-26%). All isolates were amphotericin B susceptible. Fluconazole resistance was found in 4% C. tropicalis, 12% C. glabrata (from six countries across Europe), 17% C. parapsilosis (from Greece, Italy, and Turkey) and 20% other Candida spp. Four isolates were anidulafungin and micafungin resistant/non-wild-type and five resistant to micafungin only. Three/3 and 2/5 of these were sequenced and harboured fks-alterations including a novel L657W in C. parapsilosis. The epidemiology varied among centres and countries. Acquired echinocandin resistance was rare but included differential susceptibility to anidulafungin and micafungin, and resistant C. parapsilosis. Fluconazole and voriconazole cross-resistance was common in C. glabrata and C. parapsilosis but with different geographical prevalence.

Abstract
Invasive candidiasis, including bloodstream infection (candidemia), encompasses the most severe forms of Candida infection. Several species-specific and non-specific serological assays are commercially available to aid in diagnosis. This study compared the performance of five such biomarker assays. Serum samples from 14 patients with proven or probable invasive candidiasis, and from 10 control patients, were included in the analysis. A total of 50 serum samples were tested using C. albicans germ tube antibody (CAGTA) assay (Vircell), C. albicans IgM, C. albicans IgG and Candida mannan assays (Dynamiker Biotechnology). Among these samples, the β-1-3-D-glucan (BDG) assay (Fungitell), a laboratory standard for the diagnosis of invasive candidiasis, was positive in 20 (40%), intermediate in five (10%) and negative in 25 (50%). In cases of proven or probable candidemia, the sensitivity and specificity of the BDG assay was 86% and 80%, respectively; the Candida mannan assay, 14% and 86%; the CAGTA test, 57% and 60%; the C. albicans IgM assay, 71% and 60%; and C. albicans IgG assay 29% and 90%. In 4/8 (50%) cases with multiple serum samples, C. albicans IgM was positive sooner than BDG. Thus, when used as a rule-out test for invasive candidiasis, our data suggest that the C. albicans IgM assay may assist antifungal stewardship (over serum BDG).

Abstract
The COVID-19 pandemic has undoubtedly highlighted the detrimental effect of secondary pathogens in patients with a primary viral insult. In addition to superinfections with bacterial pathogens, invasive fungal infections were increasingly reported. While the diagnosis of pulmonary fungal infections has always been challenging, it became even more problematic in the setting of COVID-19 especially when it comes to the interpretation of the radiological findings and mycology test results in these patients. Moreover, the long duration of hospitalization in intensive care units coupled with underlying host factors such as multiple comorbidities including preexisting immunosuppression, the use of immunomodulatory agents and pulmonary compromise caused additional vulnerability to fungal infections in this patient population. In addition, the heavy workload during the COVID-19 outbreak, the redeployment of untrained staff, and sometimes the lack of gloves, gown and masks has made it more difficult for many healthcare workers to strictly adhere to infection control preventive measures. Taken together, these factors favored patient to patient spread of fungal infections such as those caused by Candida auris or environment to patient transmission such as nosocomial aspergillosis. Because fungal infections were associated with increased morbidity and mortality, empiric treatment was overly used and abused in COVID-19 infected patients, potentially contributing to increased resistance in fungal pathogens. In this paper, we aim to focus on essential elements of antifungal stewardship in COVID-19 for three fungal infections, namely COVID-19 associated candidemia (CAC), pulmonary aspergillosis (CAPA) and mucormycosis (CAM).

Abstract
Secondary infections caused by the pulmonary fungal pathogen Aspergillus fumigatus are a significant cause of mortality in patients with severe coronavirus disease 19 (COVID-19). Even though epithelial cell damage and aberrant cytokine responses have been linked to susceptibility to COVID-19-associated pulmonary aspergillosis (CAPA), little is known about the mechanisms underpinning copathogenicity. Here, we analyzed the genomes of 11 A. fumigatus isolates from patients with CAPA in three centers from different European countries. CAPA isolates did not cluster based on geographic origin in a genome-scale phylogeny of representative A. fumigatus isolates. Phenotypically, CAPA isolates were more similar to the A. fumigatus A1160 reference strain than to the Af293 strain when grown in infection-relevant stresses, except for interactions with human immune cells wherein macrophage responses were similar to those induced by the Af293 reference strain. Collectively, our data indicate that CAPA isolates are genomically diverse but are more similar to each other in their responses to infection-relevant stresses. A larger number of isolates from CAPA patients should be studied to better understand the molecular epidemiology of CAPA and to identify genetic drivers of copathogenicity and antifungal resistance in patients with COVID-19. IMPORTANCE Coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) has been globally reported as a life-threatening complication in some patients with severe COVID-19. Most of these infections are caused by the environmental mold Aspergillus fumigatus, which ranks third in the fungal pathogen priority list of the WHO. However, little is known about the molecular epidemiology of Aspergillus fumigatus CAPA strains. Here, we analyzed the genomes of 11 A. fumigatus isolates from patients with CAPA in three centers from different European countries, and carried out phenotypic analyses with a view to understanding the pathophysiology of the disease. Our data indicate that A. fumigatus CAPA isolates are genomically diverse but are more similar to each other in their responses to infection-relevant stresses.

Abstract
Molds are ubiquitous in the environment, and immunocompromised patients are at substantial risk of morbidity and mortality due to their underlying disease and the resistance of pathogenic molds to currently recommended antifungal therapies. This combination of weakened-host defense, with limited antifungal treatment options, and the opportunism of environmental molds renders patients at risk and especially vulnerable to invasive mold infections such as Aspergillus and members of the Order Mucorales. Currently, available antifungal drugs such as azoles and echinocandins, as well as combinations of the same, offer some degree of efficacy in the prevention and treatment of invasive mold infections, but their use is often limited by drug resistance mechanisms, toxicity, drug-drug interactions, and the relative paucity of oral treatment options. Clearly, there is a need for agents that are of a new class that provides adequate tissue penetration, can be administered orally, and have broad-spectrum efficacy against fungal infections, including those caused by invasive mold organisms. Ibrexafungerp, an orally bioavailable glucan synthase inhibitor, is the first in a new class of triterpenoid antifungals and shares a similar target to the well-established echinocandins. Ibrexafungerp has a very favorable pharmacokinetic profile for the treatment of fungal infections with excellent tissue penetration in organs targeted by molds, such as the lungs, liver, and skin. Ibrexafungerp has demonstrated in vitro activity against Aspergillus spp. as well as efficacy in animal models of invasive aspergillosis and mucormycosis. Furthermore, ibrexafungerp is approved for use in the USA for the treatment of women with vulvovaginal candidiasis. Ibrexafungerp is currently being evaluated in clinical trials as monotherapy or in combination with other antifungals for treating invasive fungal infections caused by yeasts and molds. Thus, ibrexafungerp offers promise as a new addition to the clinician's armamentarium against these difficult-to-treat infections.

Abstract
Recurrent vulvovaginal candidiasis (RVVC) is a debilitating, chronic condition that affects over 138 million (6%) women of reproductive age annually. We performed a retrospective audit of RVVC referrals to our tertiary care Candida clinic to evaluate the impact of the significantly updated British Association of Sexual Health and HIV (BASHH) 2019 vulvovaginal candidiasis guidelines on patient outcomes, the principles of which were implemented at our centre at the onset of the guideline revision process in 2017. A total of 78 women referred with suspected RVVC in 2017–2020 were included. Their mean symptom duration prior to referral was 6.7 years. RVVC was the definitive diagnosis in 73% of cases. In the 27% of patients without RVVC, the most common diagnoses were acute VVC (29%), vulval eczema (14%), dry skin (14%) and vulvodynia (10%). Of those with RVVC, 60% were diagnosed with an additional diagnosis, most commonly vulval eczema or vulvodynia. Only 12% of women had been counselled on appropriate vulval skin care, the mainstay of RVVC management. Long-term antifungal suppression was initiated in 68% of women. Azole-resistant Candida, for which there is no licensed treatment available in the UK, was identified in 23% of women with RVVC. In the follow-up, 82% of patients reported good control of symptoms using antifungal suppression therapy and recommended skin care, 16% had partial symptom control with some “flare-ups” responding to treatment, none reported poor control and for 2% this information was not available. RVVC-related morbidity can be reduced by following the principles outlined in the BASHH guidelines.

Abstract
INTRODUCTION Intra-abdominal infections represent the second most frequently acquired infection in the intensive care unit (ICU), with mortality rates ranging from 20% to 50%. Candida spp. may be responsible for up to 10-30% of cases. This study assesses risk factors for development of intra-abdominal candidiasis (IAC) among patients admitted to ICU. METHODS We performed a case-control study in 26 European ICUs during the period January 2015-December 2016. Patients at least 18 years old who developed an episode of microbiologically documented IAC during their stay in the ICU (at least 48 h after admission) served as the case cohort. The control group consisted of adult patients who did not develop episodes of IAC during ICU admission. Matching was performed at a ratio of 1:1 according to time at risk (i.e. controls had to have at least the same length of ICU stay as their matched cases prior to IAC onset), ICU ward and period of study. RESULTS During the study period, 101 case patients with a diagnosis of IAC were included in the study. On univariate analysis, severe hepatic failure, prior receipt of antibiotics, prior receipt of parenteral nutrition, abdominal drain, prior bacterial infection, anastomotic leakage, recurrent gastrointestinal perforation, prior receipt of antifungal drugs and higher median number of abdominal surgical interventions were associated with IAC development. On multivariate analysis, recurrent gastrointestinal perforation (OR 13.90; 95% CI 2.65-72.82, p = 0.002), anastomotic leakage (OR 6.61; 95% CI 1.98-21.99, p = 0.002), abdominal drain (OR 6.58; 95% CI 1.73-25.06, p = 0.006), prior receipt of antifungal drugs (OR 4.26; 95% CI 1.04-17.46, p = 0.04) or antibiotics (OR 3.78; 95% CI 1.32-10.52, p = 0.01) were independently associated with IAC. CONCLUSIONS Gastrointestinal perforation, anastomotic leakage, abdominal drain and prior receipt of antifungals or antibiotics may help to identify critically ill patients with higher probability of developing IAC. Prospective studies are needed to identify which patients will benefit from early antifungal treatment.

Abstract
INTRODUCTION Fungal PCR has undergone considerable standardization and together with the availability of commercial assays, external quality assessment schemes and extensive performance validation data, is ready for widespread use for the screening and diagnosis of invasive fungal disease (IFD). AREAS COVERED Drawing on the experience and knowledge of the leads of the various working parties of the Fungal PCR initiative, this review will address general considerations concerning the use of molecular tests for the diagnosis of IFD, before focussing specifically on the technical and clinical aspects of molecular testing for the main causes of IFD and recent technological developments. EXPERT OPINION For infections caused by Aspergillus, Candida and Pneumocystis jirovecii, PCR testing is recommended, combination with serological testing will likely enhance the diagnosis of these diseases. For other IFD (e.g. Mucormycosis) molecular diagnostics, represent the only non-classical mycological approach towards diagnoses and continued performance validation and standardization has improved confidence in such testing. The emergence of antifungal resistance can be diagnosed, in part, through molecular testing. Next-generation sequencing has the potential to significantly improve our understanding of fungal phylogeny, epidemiology, pathogenesis, mycobiome/microbiome and interactions with the host, while identifying novel and existing mechanisms of antifungal resistance and novel diagnostic/therapeutic targets.

Abstract
Background Candida species are a major cause of invasive and mucocutaneouls infections. There are limited oral treatment options available for patients with Candida infections who are unresponsive to or who are intolerant of currently available antifungals. Oral ibrexafungerp is an investigational broad-spectrum glucan synthase inhibitor antifungal with activity against Candida and Aspergillus species, including azole- and echinocandin-resistant strains. A Phase 3 open-label, single-arm study of ibrexafungerp (FURI; NCT03059992) is ongoing for the treatment of patients intolerant of or with fungal disease refractory to standard antifungal therapy. We present an analysis of patient outcomes from the FURI study by fungal disease type. Table 1: FURI Outcomes by Fungal Disease ![]()
Methods FURI patients were eligible for enrollment if they have proven or probable, severe mucocutaneous candidiasis, invasive candidiasis or invasive aspergillosis,other fungal diseases and evidence of failure to, intolerance to, or toxicity related to a currently approved standard-of-care antifungal treatment or can not receive approved oral antifungal options (e.g., susceptibility of the organism) and a continued IV antifungal therapy is clinically undesirable or unfeasible. Results An independent Data Review Committee (DRC) provided an assessment of treatment response for 74 patients enrolled in the FURI study from 22 centers in US, UK and EU treated with ibrexafungerp for mucocutaneous or invasive fungal infections from 2016- 2020. A total of 39 (52.7%) patients had invasive candidiasis, 32 (43.2%) had mucocutaneous candidiasis and 3 (4.5%) patients had invasive aspergillosis. The percent of patients who were determined to have a complete response (CR), partial response (PR), clinical improvement (CI) was 63.5%, stable disease (SD) was 23.0%, patients with progression of disease 6.8% and 4 patients were indeterminate. Additionally, there was 1 death in the FURI study that was not related to fungal disease. Table 1 shows outcomes by fungal disease type as determined by the DRC. Conclusion Analysis of 74 patients from the FURI study indicates that oral ibrexafungerp provides a favorable therapeutic response in patients with challenging fungal disease and limited treatment options.

Abstract
Abstract
Background
Candida albicans is the predominant organism causing esophageal candidiasis (EC) and oropharyngel candidiasis (OPC). These infections may arise from subjects colonized with Candida who are predisposed due to illness, debility or a local reduction in host resistance to an overgrowth of their own indigenous flora. Patients with mucocutaneous Candida infections can be treated in the outpatient setting, yet there are limited oral treatment options available for patients who are unresponsive to or who are intolerant to currently available antifungals. Oral ibrexafungerp is an investigational broad-spectrum glucan synthase inhibitor antifungal with activity against Candida species, including azole- and echinocandin-resistant strains. A Phase 3 open-label, single-arm study of ibrexafungerp (FURI; NCT03059992) is ongoing for the treatment of patients intolerant of or with fungal disease refractory to standard antifungal therapy.
Table 1. FURI Outcomes in OPC and EC
Methods
FURI subjects were eligible for enrollment if they had proven or probable severe mucocutaneous candidiasis, invasive candidiasis, invasive aspergillosis, or other fungal diseases with evidence of treatment failure, intolerance, or toxicity related to a currently approved standard-of-care antifungal treatment or if they were unable to receive an approved oral antifungal option (e.g., susceptibility of the organism) and a continued IV antifungal therapy was clinically undesirable or unfeasible.
Results
An independent Data Review Committee (DRC) provided an assessment of treatment response for 74 subjects enrolled in the FURI study from 22 centers in US, UK and EU treated with ibrexafungerp for mucocutaneous or invasive fungal infections from 2016- 2020. A total 32 subjects (43.2%) had mucocutaneous candidiasis and 24 subjects were diagnosed with OPC or EC. The percent of patients who were determined to have a complete response (CR) or partial response (PR) was 62.5%, stable disease (SD), 20.8%, and progression of disease, 16.7%. Table 1 shows outcomes by EC and OPC as determined by the DRC.
Conclusion
Analysis of 24 EC and OPC patients from the FURI study indicates that oral ibrexafungerp provides a favorable therapeutic response in patients with challenging mucocutaneous fungal disease and limited treatment options.

Abstract
Objectives Chronic pulmonary aspergillosis (CPA) can complicate recovery from pulmonary TB. CPA may also be misdiagnosed as bacteriologically negative TB. This study aimed to determine the incidence of CPA in patients treated for TB in Indonesia, a country with a high incidence of TB. Methods In this prospective, longitudinal cohort study in patients treated for pulmonary TB, clinical, radiological and laboratory findings were analysed. Sputum was collected for fungal culture and TB PCR. Patients were assessed at baseline (0–8 weeks) and at the end (5–6 months) of TB therapy. CPA diagnosis was based on symptoms (≥3 months), characteristic radiological features and positive Aspergillus serology, and categorised as proven, probable and possible. Results Of the 216 patients recruited, 128 (59%) were followed up until end of TB therapy. At baseline, 91 (42%) had microbiological evidence for TB. Aspergillus-specific IgG was positive in 64 (30%) patients and went from negative to positive in 16 (13%) patients during TB therapy. The incidence rates of proven and probable CPA at baseline were 6% (n=12) and 2% (n=5) and end of TB therapy 8% (n=10) and 5% (n=7), respectively. Six patients (two with confirmed TB) developed an aspergilloma. Diabetes mellitus was a significant risk factor for CPA (p=0.040). Persistent cough (n=5, 50%; p=0.005) and fatigue (n=6, 60%; p=0.001) were the most common symptoms in CPA. Conclusion CPA should be considered a relatively frequent differential diagnosis in patients with possible or proven TB in Indonesia. Lack of awareness and limited access to Aspergillus-specific IgG tests and CT imaging are obstacles in establishing a CPA diagnosis.

Abstract
Topical antiseptics are used to assist and further increase the effect of mechanical biofilm eradication and to potentially prevent new biofilm formation in periodontal treatment. This is of importance in treatment-resistant infections with 10% prevalence of all periodontitis cases to avoid the need for antibiotic therapy. The purpose of this study was to evaluate the antimicrobial activity of DL-2-hydroxyisocaproic acid on human pathogenic obligate anaerobic bacteria related to periodontitis. In this study antimicrobial activity of 2-hydroxyisocaproic acid was observed against 14 bacterial reference strains and clinical isolates of obligate anaerobic bacterial species using a microdilution method in 1.25 to 160 mg/mL concentrations of 2-hydroxyisocaproic acid. The 11 strains of bacteria included in this study are typically associated with periodontal disease; Porphyromonas gingivalis, Fusobacterium nucleatum, Tannerella forsythia, Aggregatibacter actinomycetemcomitans, and Parvimonas micra. Three strains of Cutibacterium acnes, normally associated with skin diseases, were tested for comparison. 90% inhibitory concentration was determined at 48 hours and minimum bactericidal concentration was determined after 72 hours incubation. The 2-hydroxyisocaproic acid was bactericidal at ⩾160 mg/mL for all isolates tested. The reference strain of T. forsythia, and the reference strain and the clinical isolates of C. acnes were the most tolerant ones. The reference strains and clinical isolates of F. nucleatum and A. actinomycetemcomitans were killed at ⩾40 mg/mL concentration. In conclusion, topical use of 2-hydroxyisocaproic acid could eventually be a well-tolerated and useful method in the therapy of patients with difficult-to-treat periodontal disease or other superficial infections to avoid unnecessary antibiotic use and the emergence of antibiotic resistance.

Abstract
This single-centre retrospective study reports the dynamics of candida bloodstream infection (CBSI) incidence in 145 patients receiving venovenous ECMO for respiratory support, between January 2014 and December 2018. Incidence rate and odds ratio (OR) of CBSI were calculated, stratified by week of ECMO exposure. Weekly incidence increased throughout the ECMO run, with a rising trend in OR (P = 0.005), and a window of continued risk after decannulation was observed. Of the 13 patients that developed CBSI, five (38%) received empirical micafungin treatment before positive culture due to clinical suspicion. Prospective studies, aiming to improve ECMO diagnostic stewardship practices and discourage antifungal prophylaxis or empiric management where unnecessary, are needed.

Abstract
AIM To develop a defined multispecies root canal biofilm model ex vivo, and to perform viable compositional analysis following D,L-2-hydroxyisocaproic acid (HICA), alpha-mangostin, Calcicur® , and Odontopaste® exposure. METHODOLOGY Time-kill assays were conducted in vitro using HICA, alpha-mangostin, Calcicur® , Odontopaste® , and saline solution on the planktonic cultures of C. albicans, E. faecalis, L. rhamnosus, and S. gordonii. Human root dentine blocks were prepared (n = 100) ex vivo, and multispecies suspensions containing each of 1.5 × 108 CFU/mL C. albicans, E. faecalis, L. rhamnosus, and S. gordonii in brain heart infusion (BHI) were incubated within the root canals for 21 days. Canals (n = 20/group) were then exposed to medicaments for 7 days. Samples taken from the inner (first 0.1 mm) and deeper (second 0.1 mm) dentine by drilling with Ash Steel Burs No. 5 and No. 6, and residual roots were cultured in broth for 24 h. Cell growth was detected by spectrophotometry and confirmed by culture on agar. The other set of inner dentine, deeper dentine, and residual root samples were sonicated, and then exposed with 50 μM PMA before DNA was extracted using the QIAamp DNA mini kit. Real-time quantitative PCR was performed to determine the biofilm composition as well as the number of live and total cells remaining in the biofilm following each treatment. The OD data were analysed with Kruskal-Wallis and Friedman with Wilcoxon signed-rank test between and within groups, respectively, agar culture and qPCR data with Pearson chi-square with Mann-Whitney and Cochran with McNemar tests, respectively (p < .0001). RESULTS Time-kill assays revealed that HICA and Calcicur® killed all planktonic organisms within 24 h, whilst alpha-mangostin killed the organisms within 72 h. However, Odontopaste® was a slow-killing agent: 10 cells of planktonic organisms survived after exposure to the agent for 7 days. The ex vivo tooth model demonstrated that HICA and alpha-mangostin significantly inhibited the cell growth in all sampling depths (p < .0001). All species-specific data revealed the effectiveness of each medicament on the biofilm composition. CONCLUSIONS D,L-2-hydroxyisocaproic acid and alpha-mangostin had antimicrobial activity against multispecies bacterial-fungal biofilms.

Abstract
Objectives Coronavirus disease 2019 (COVID-19) -associated pulmonary aspergillosis (CAPA) has emerged as a complication in critically ill COVID-19 patients. The objectives of this multinational study were to determine the prevalence of CAPA in patients with COVID-19 in intensive care units (ICU) and to investigate risk factors for CAPA as well as outcome. Methods The European Confederation of Medical Mycology (ECMM) conducted a multinational study including 20 centres from nine countries to assess epidemiology, risk factors and outcome of CAPA. CAPA was defined according to the 2020 ECMM/ISHAM consensus definitions. Results A total of 592 patients were included in this study, including 11 (1.9%) patients with histologically proven CAPA, 80 (13.5%) with probable CAPA, 18 (3%) with possible CAPA and 483 (81.6%) without CAPA. CAPA was diagnosed a median of 8 days (range 0–31 days) after ICU admission predominantly in older patients (adjusted hazard ratio (aHR) 1.04 per year; 95% CI 1.02–1.06) with any form of invasive respiratory support (HR 3.4; 95% CI 1.84–6.25) and receiving tocilizumab (HR 2.45; 95% CI 1.41–4.25). Median prevalence of CAPA per centre was 10.7% (range 1.7%–26.8%). CAPA was associated with significantly lower 90-day ICU survival rate (29% in patients with CAPA versus 57% in patients without CAPA; Mantel–Byar p < 0.001) and remained an independent negative prognostic variable after adjusting for other predictors of survival (HR 2.14; 95% CI 1.59–2.87, p ≤ 0.001). Conclusion Prevalence of CAPA varied between centres. CAPA was significantly more prevalent among older patients, patients receiving invasive ventilation and patients receiving tocilizumab, and was an independent strong predictor of ICU mortality.

Abstract
Background Infections caused by triazole drug-resistant Aspergillus fumigatus are an increasing problem. The sensitivity of standard culture is poor, abrogating susceptibility testing. Early detection of resistance can improve patient outcomes, yet tools for this purpose are limited. Objectives To develop and validate a pyrosequencing technique to detect resistance-conferring cyp51A polymorphisms from clinical respiratory specimens and A. fumigatus isolates. Methods Method validation was performed by Sanger sequencing and pyrosequencing of 50 A. fumigatus isolates with a spectrum of triazole susceptibility patterns. Then, 326 Aspergillus quantitative PCR (qPCR)-positive respiratory samples collected over a 27 month period (January 2017–March 2019) from 160 patients at the UK National Aspergillosis Centre were assessed by cyp51A pyrosequencing. The Sanger sequencing and pyrosequencing results were compared with those from high-volume culture and standard susceptibility testing. Results The cyp51A genotypes of the 50 isolates analysed by pyrosequencing and Sanger sequencing matched. Of the 326 Aspergillus qPCR-positive respiratory specimens, 71.2% were reported with no A. fumigatus growth. Of these, 56.9% (132/232) demonstrated a WT cyp51A genotype and 31.5% (73/232) a resistant genotype by pyrosequencing. Pyrosequencing identified the environmental TR34/L98H mutation in 18.7% (61/326) of the samples in contrast to 6.4% (21/326) pan-azole resistance detected by culture. Importantly, pyrosequencing detected resistance earlier than culture in 23.3% of specimens. Conclusions The pyrosequencing assay described could detect a wide range of cyp51A polymorphisms associated with triazole resistance, including those not identified by commercial assays. This method allowed prompt recognition of resistance and the selection of appropriate antifungal treatment when culture was negative.

Abstract
Quantitative real-time PCR (qPCR) is increasingly used to detect Pneumocystis jirovecii for the diagnosis of Pneumocystis pneumonia (PCP), but there are differences in the nucleic acids targeted, DNA only versus whole nucleic acid (WNA), and also the target genes for amplification. Through the Fungal PCR Initiative, a working group of the International Society for Human and Animal Mycology, a multicenter and monocenter evaluation of PCP qPCR assays was performed. For the multicenter study, 16 reference laboratories from eight different countries, performing 20 assays analyzed a panel consisting of two negative and three PCP positive samples. Aliquots were prepared by pooling residual material from 20 negative or positive- P. jirovecii bronchoalveolar lavage fluids (BALFs). The positive pool was diluted to obtain three concentrations (pure 1:1; 1:100; and 1:1000 to mimic high, medium, and low fungal loads, respectively). The monocenter study compared five in-house and five commercial qPCR assays testing 19 individual BALFs on the same amplification platform. Across both evaluations and for all fungal loads, targeting WNA and the mitochondrial small sub-unit (mtSSU) provided the earliest Cq values, compared to only targeting DNA and the mitochondrial large subunit, the major surface glycoprotein or the beta-tubulin genes. Thus, reverse transcriptase-qPCR targeting the mtSSU gene could serve as a basis for standardizing the P. jirovecii load, which is essential if qPCR is to be incorporated into clinical care pathways as the reference method, accepting that additional parameters such as amplification platforms still need evaluation.

Abstract
INTRODUCTION Isolation of Exophiala species from sputum samples has become increasingly reported in Cystic Fibrosis (CF). However, the clinical significance of Exophiala spp. with regards to the paediatric CF population is unknown. METHODS A case control study was undertaken to compare CF children with and without chronic Exophiala spp. in their sputum samples. Demographic and clinical data were collected retrospectively for each case from the date of Exophiala isolation and for 12 months preceding isolation. Each case was compared to three age and year-matched controls. To determine the effect of Exophiala on clinical course, patients were then followed for 12 months post isolation. RESULTS In total, 27 of 244 eligible paediatric CF patients (11%) isolated Exophiala spp. on more than one occasion. There were no significant differences in the key clinical parameters: spirometry, mean number of intravenous (IV) antibiotic days and body mass index (BMI), between cases and controls (p = 0.91, p = 0.56 and p = 0.63 respectively). A higher proportion of cases isolated Candida spp. (67% vs 21%, p < 0.0001) and Aspergillus fumigatus (37% vs 26%, p = 0.37). There was no clinically significant difference in spirometry, mean number of IV antibiotic days and BMI in cases pre and post Exophiala spp. isolation. Posaconazole was the only drug used that successfully eradicated Exophiala. CONCLUSION Despite the frequent isolation of Exophiala spp. in this cohort, in most patients it is not associated with significant clinical deterioration. It does however seem to be associated with isolation of other fungi.

Abstract
Molecular fungal genotyping techniques developed and employed for epidemiological studies have understandably concentrated on establishing the genetic diversity of Aspergillus fumigatus in invasive aspergillosis due to its severity, the urgency for treatment, and the need to demonstrate possible sources. Some early studies suggested that these strains were phenotypically, if not genotypically, different from others. However, with improved discrimination and evaluations, incorporating environmental as well as clinical isolates from other Aspergillus conditions (e.g., chronic pulmonary aspergillosis and cystic fibrosis), this premise is no longer upheld. Moreover, with the onset of increased global triazole resistance, there has been a concerted effort to incorporate resistance profiling into genotyping studies and the realisation that the wider population of non-immunocompromised aspergillosis patients are at risk. This review summarises the developments in molecular genotyping studies that incorporate resistance profiling with attention to chronic pulmonary aspergillosis and an example of our UK experience.

Abstract
OBJECTIVES To evaluate the efficacy of single-dose antibiotic prophylaxis (AP) in the prevention of bacteraemia following tooth extractions at our clinic. MATERIAL AND METHODS Fifty patients undergoing tooth extractions were enrolled. The need of AP was determined according to the health status and possible allergies of the patients. Blood culture samples were collected at baseline, 5 min after the first tooth extraction and 20 min after the last extraction. RESULTS The majority (76%) received prophylactic oral amoxicillin or intravenous ampicillin (AMX/AMP) (2 g), 12% received clindamycin (CLI) (600 mg) and 12% received no prophylaxis (NO AP). All baseline blood cultures were reported negative. The prevalence of bacteraemia was significantly higher in the CLI and NO AP groups compared to the AMX/AMP group 5 min after the first tooth extraction (p < .0001 and p = .015, respectively). Twenty minutes after the last extraction positive blood cultures were reported only for CLI (p = .0015) and NO AP groups. There was no significant difference in the prevalence of positive blood cultures between CLI and NO AP groups. CONCLUSIONS Appropriately administered AMX/AMP proved its efficacy in reducing both the prevalence and duration of bacteraemia following tooth extractions whereas CLI was not effective in preventing bacteraemia following tooth extractions.

Abstract
Background
Candida infections resistant to currently available antifungals are an emerging global threat. Ibrexafungerp is an investigational broad-spectrum glucan synthase inhibitor antifungal with activity against Candida and Aspergillus species, including azole- and echinocandin-resistant strains. A Phase 3 open-label, single-arm study of oral ibrexafungerp (FURI) (Clinicaltrials.gov NCT03059992) is ongoing for the treatment of patients (≥18 years) with fungal diseases who are intolerant of or refractory to standard antifungal therapies.
Methods
An independent Data Review Committee (DRC) provided an assessment of treatment response for 41 patients. Patients were enrolled in 22 centers from 6 countries. Patients were eligible for enrollment if they had proven or probable, invasive or severe mucocutaneous candidiasis and documented evidence of failure of, intolerance to, or toxicity related to a currently approved standard-of-care antifungal treatment or could not receive approved oral antifungal options (e.g., susceptibility of the organism) and a continued IV antifungal therapy was undesirable or unfeasible.
Results
The 41 patients assessed had the following infection types: intra-abdominal abscesses, oropharyngeal candidiasis, esophageal candidiasis, candidemia, and others. The DRC adjudicated 23 patients (56%) as achieving complete or partial response, 11 patients (27%) maintaining stable disease, 6 patients (15%) with progression of disease and one case was considered as indeterminate. The efficacy of oral ibrexafungerp by pathogen is shown in Table 1. Ibrexafungerp was well-tolerated with the most common treatment-related adverse events being of gastrointestinal origin. No deaths due to progression of fungal disease were reported.

Conclusion
Preliminary analysis of these 41 cases indicate that oral ibrexafungerp provides a favorable therapeutic response in the majority of patients with difficult to treat Candida spp. infections, including those caused by non-albicans Candida species.

Abstract
OBJECTIVES The objective of this study was to investigate the association between p53 expression and microbial acetaldehyde production in patients with oral squamous cell carcinoma (OSCC). STUDY DESIGN Oral mucosal biopsies from 22 patients with OSCC and 24 healthy controls (HCs) were collected. p53 expression was analyzed by immunohistochemistry. Microbial samples were collected from the mucosa and microbial acetaldehyde production from ethanol was measured by gas chromatography. RESULTS The majority of all OSCC (77%) and HC samples (67%) produced mutagenic levels of acetaldehyde (>100 µM). A significant positive correlation between microbial acetaldehyde production and p53 expression levels in OSCC samples was seen in the intermediate and superficial layers of the epithelium of the infiltrative zone (P = .0005 and P = .0004, respectively) and in the superficial layer of the healthy appearing mucosa next to the tumor (P = .0391). There was no significant correlation between acetaldehyde levels and p53 expression in HC samples. CONCLUSIONS Our results show an association between microbial acetaldehyde production and immunostaining of p53 in OSCC samples.

Abstract
Background In the UK there is limited coverage of antimicrobial stewardship across postgraduate curricula and evidence that final year medical students have insufficient and inconsistent antimicrobial stewardship teaching. A national undergraduate curriculum for antimicrobial resistance and stewardship is required to standardize an adequate level of understanding for all future doctors. Objectives To provide a UK national consensus on competencies for antimicrobial resistance and stewardship for undergraduate medical education. Methods Using the modified Delphi method over two online survey rounds, an expert panel comprising leads for infection teaching from 25 UK medical schools reviewed competency descriptors for antimicrobial resistance and stewardship education. Results There was a response rate of 100% with all 28 experts who agreed to take part completing both survey rounds. Following the first-round survey, of the initial 55 descriptors, 43 reached consensus (78%). The second-round survey included the 12 descriptors from the first round in which agreement had not been reached, four amended descriptors and 12 new descriptors following qualitative feedback from the panel members. Following the second-round survey, a total of 58 consensus-based competency descriptors within six overarching domains were identified. Conclusions The consensus-based competency descriptors defined here can be used to inform standards, design curricula, develop assessment tools and direct UK undergraduate medical education.

Abstract
The emergence of azole-resistant Aspergillus fumigatus (ARAf) complicates the treatment of aspergillosis and can nearly double the mortality from invasive aspergillosis (IA). ARAf has been isolated from many different environmental sites and indoor environments and thus presents a significant risk for susceptible patients. Local surveillance of environmental ARAf can guide antifungal prescribing and improve patient outcomes. In this study, seventy-four soils samples collected from the surface of a variety of root vegetables from farm shops and private gardens covering a wide geographical area of the UK, were cultured to assess the presence of A. fumigatus, and the prevalence and nature of any resistance mechanisms. A high-throughput in-house antifungal susceptibility screening method was developed and validated using the EUCAST MIC reference method, E.DEF 9.3.1. A total of 146 isolates were recovered and analysed. Even though the study premise was that soil-covered root vegetables and other fresh produce could represent a conduit for ARAf exposure in vulnerable patients, no ARAf were found in the soil samples despite 55% of samples harbouring A. fumigatus. The sample type and screening method used could be suitable for more extensive monitoring of the soil to detect trends in the prevalence of ARAf.

Abstract
Talaromycosis is a fungal infection endemic in Southeast Asia. We report a case of a renal transplant recipient who developed infection after a trip to South China. She presented with constitutional symptoms and was found to have an FDG-avid lung mass. Histopathology demonstrated small yeast cells and culture grew Talaromyces marneffei. The patient was treated with 2 weeks of liposomal amphotericin B followed by itraconazole. The dose of tacrolimus was significantly reduced because of the interaction with itraconazole. Mycophenolate mofetil was discontinued. After 12 months of treatment, the mass had completely resolved. Talaromycosis has mainly been reported in patients with AIDS and is uncommon among solid organ transplant recipients. The immune response against T. marneffei infection is mediated predominantly by T cells and macrophages. The diagnosis may not be suspected outside of endemic areas. We propose a therapeutic approach in transplant patients by extrapolating the evidence from the HIV literature and following practices applied to other endemic mycoses.

Abstract
Pulmonary tuberculosis (TB) is one of the common risk factors for chronic pulmonary aspergillosis (CPA). A positive Aspergillus IgG is a key element of the diagnosis of CPA but this has not been studied in Indonesia. We conducted studies with patients at the end of TB therapy in Indonesia. We performed receiver operating curve (ROC) analysis to determine the optimum cutoff of the Aspergillus-specific IgG level (Immulite and Dynamiker ELISA) in those patients who met criteria of CPA in relation to control groups. In 203 TB patients, 26 (13%) patients had clinical and radiological features of CPA. We derived optimum cutoffs for Immulite Aspergillus-specific IgG of 11.5 mg/L and Dynamiker anti-galactomannan IgG of 106.8 AU/mL (sensitivity 89% and 83%, specificity 78% and 51%, respectively). The currently accepted Aspergillus-specific IgG cutoff of Immulite and Dynamiker assays for CPA diagnosis may require slight adjustment for the Indonesian population.

Abstract
BACKGROUND Posaconazole delayed-release tablets offer better bioavailability than the liquid suspension, but no post-marketing data are available in immunocompetent hosts such as those with chronic pulmonary aspergillosis (CPA). OBJECTIVES To explore the pharmacokinetics and adverse event (AE) profile of posaconazole tablets in patients with CPA. METHODS Patients started on posaconazole tablets at the National Aspergillosis Centre (NAC), Manchester, UK between February 2014 and October 2015 were identified from the NAC database and analysed retrospectively. The medical records were reviewed for factors that could affect posaconazole serum levels and the development of AEs. RESULTS Seventy-two patients were included; 50 (69%) were male and the mean age was 48.5 ± 12 years. Therapeutic levels (≥1 mg/L) were achieved in 90% of cases on 200 mg versus 90% of cases on 300 mg daily (P = not significant). Based on multivariate analysis, female sex (P = 0.041), a 100 mg daily dose (P < 0.001), asthma (P = 0.01) and bronchiectasis (P = 0.001) were associated with subtherapeutic levels. Forty-nine (68%) patients developed AEs, mainly fatigue (37%), dyspnoea (18%) and nausea (12%). AEs were present on 115/196 (59%) occasions on 300 mg/day and on 45/115 (39%) occasions on 200 mg/day (P < 0.01). The mean level was 1.81 ± 0.96 mg/L for patients reporting no AEs and 1.90 ± 1.11 mg/L for those reporting AEs (P = not significant). Factors associated with AEs of grade ≥2 were a daily dose of 300 versus 200 mg (P = 0.001) and asthma (P = 0.008). CONCLUSIONS A lower-than-recommended posaconazole tablet dose achieved therapeutic levels in most patients and was better tolerated. Males were more likely to achieve a therapeutic level. Underlying conditions affected the degree and frequency of AEs.

Abstract
Abstract
OBJECTIVES
Surgical resection is one treatment modality for chronic pulmonary aspergillosis (CPA), and sometimes a preoperative presumption of lung cancer turns out to be CPA. We have audited our surgical experience with regard to risk factors for relapse, and the value of postoperative monitoring of Aspergillus-immunogolubulin G (IgG) titres.
METHODS
All patients with CPA surgically treated at National Aspergillosis Centre (NAC), Manchester, UK (2007–2018), were retrospectively evaluated. Surgical procedures, underlying disorders, Aspergillus-IgG titres (ImmunoCap) and antifungal therapy were evaluated for symptom control, operative complications, CPA relapse and mortality.
RESULTS
A total of 61 patients with CPA (28 males, 33 females) were operated on primarily for antifungal therapy failure (51%, n = 31) and presumed lung malignancies (38%, n = 23). Procedures included lobectomy (64%, n = 39), wedge resection (28%, n = 17), segmentectomy (n = 3), pneumonectomy (n = 3) and decortication (n = 2). Overall, 25 (41%) patients relapsed, 26 months (standard deviation: 24.8 months) after surgery. Antifungal therapy before surgery (P = 0.002) or both before and after surgery (P = 0.005) were protective for relapse. The relapse rate within 3 years after surgery (33%, n = 20) was higher than the 3–10 years after surgery (8%, n = 5). At the end of follow-up, the median Aspergillus-IgG titre was lower than at relapse in 12 patients (67 vs 126 mg/l) (P = 0.016).
CONCLUSIONS
Surgery in these selected patients with CPA resulted in favourable outcomes. Relapse is common after surgical treatment of CPA but can be minimized with antifungal therapy, emphasizing the importance of an accurate diagnosis prior to surgery.

Abstract
OBJECTIVES Difficult-to-treat invasive fungal infections require infectious diseases expert consultation to improve treatment outcome and increase survival rates. METHODS The European Confederation of Medical Mycology (ECMM) intends to provide expert help free of charge by a newly founded ECMM Expert Consultation Service for medical centres around the globe seeking advice when there is no fungal infection consultant available. The expert consult will provide recommendations and broad expertise on difficult-to-treat invasive fungal infections (eg azole-resistant Aspergillus species, Candida auris, mucormycosis) to improve diagnostic and therapeutic management and outcome. RESULTS The initiative plans global outreach through video conferencing between ECMM Excellence Centers and treating physicians. FungiScope® registries will be used to structure case information and to evaluate the impact of the collegial advice system at regular intervals. Advice will follow recent guidelines, and EQUAL Scores will be used to measure guideline adherence. CONCLUSIONS Infectious diseases expert consultation should be an integral component of care for patients with difficult-to-treat invasive fungal infections. The ECMM Expert Consult will attend to this matter on a global scale.

Abstract
Guidelines on the diagnosis and management of Aspergillus disease recommend a multi-test approach including CT scans, culture, fungal biomarker tests, microscopy and fungal PCR. The first-line treatment of confirmed invasive aspergillosis (IA) consists of drugs in the azole family; however, the emergence of azole-resistant isolates has negatively impacted the management of IA. Failure to detect azole-resistance dramatically increases the mortality rates of azole-treated patients. Despite drug susceptibility tests not being routinely performed currently, we suggest including resistance testing whilst diagnosing Aspergillus disease. Multiple tools, including DNA sequencing, are available to screen for drug-resistant Aspergillus in clinical samples. This is particularly beneficial as a large proportion of IA samples are culture negative, consequently impeding susceptibility testing through conventional methods. Pyrosequencing is a promising in-house DNA sequencing method that can rapidly screen for genetic hotspots associated with antifungal resistance. Pyrosequencing outperforms other susceptibility testing methods due to its fast turnaround time, accurate detection of polymorphisms within critical genes, including simultaneous detection of wild type and mutated sequences, and—most importantly—it is not limited to specific genes nor fungal species. Here we review current diagnostic methods and highlight the potential of pyrosequencing to aid in a diagnosis complete with a resistance profile to improve clinical outcomes.

Abstract
Clinically relevant members of the Mucorales group can grow and are found in diverse ecological spaces such as soil, dust, water, decomposing vegetation, on and in food, and in hospital environments but are poorly represented in mycobiome studies of outdoor and indoor air. Occasionally, Mucorales are found in water-damaged buildings. This mini review examines a number of specialised biotic environments, including those revealed by natural disasters and theatres of war, that support the growth and persistence of these fungi. However, we are no further forward in understanding exposure pathways or the chronicity of exposure that results in the spectrum of clinical presentations of mucormycosis.

Abstract
OBJECTIVES Sputum culture is an insensitive method for the diagnosis of pulmonary aspergillosis. Growth of the organism allows identification of the causative species and susceptibility testing, both of which can inform treatment choices. The current practice is to culture an aliquot of diluted sputum. We assessed the value of culturing large volumes of unprocessed sputum, a method that we have termed high-volume culture (HVC). METHODS Specimens were processed by conventional culture (using an aliquot of homogenized, diluted sputum on Sabouraud agar at 37°C and 45°C for up to 5 days) and HVC (using undiluted sputum on Sabouraud agar at 30°C for up to 14 days). A separate specimen was tested by quantitative real-time PCR. Antifungal susceptibility testing was performed by the EUCAST standard. RESULTS We obtained sputum specimens from 229 individuals with the following conditions: chronic pulmonary aspergillosis (66.8%, 153/229), allergic bronchopulmonary aspergillosis (25.3%, 58/229) and Aspergillus bronchitis (7.9%, 18/229). Individuals with invasive pulmonary aspergillosis were not included. The positivity rate of conventional culture was 15.7% (36/229, 95% CI 11.6%-21.0%) and that of HVC was 54.2% (124/229, 95% CI 47.7%-60.5%) (p < 0.001). The higher positivity rate of HVC was demonstrated regardless of administration of antifungal treatment. Quantitive real-time PCR had an overall positivity rate of 49.2% (65/132, 95% CI 40.9%-57.7%), comparable to that of HVC. CONCLUSION Detection of Aspergillus spp. in sputum is greatly enhanced by HVC. HVC allows for detection of azole-resistant isolates that would have been missed by conventional culture. This method can be performed in any microbiology laboratory without the need for additional equipment.

Abstract
Objectives A concise invasive candidosis guideline (based on the ESCMID candidaemia guideline) utilizing an informative biomarker [serum β-1-3-d-glucan (BDG)] was developed in 2013 by an antifungal stewardship (AFS) team and implemented with the help of an AFS champion in 2014. The main aims of the AFS programme were to reduce inappropriate use of antifungals and improve patient outcomes. The aim of this project was to evaluate the compliance of the ICU teams with the invasive candidosis guideline and the impact of the AFS programme on mortality and antifungal consumption on the ICUs (total of 71 beds). Methods All patients who were prescribed micafungin for suspected or proven invasive candidosis during 4 month audit periods in 2014 and 2016 were included. Prescriptions and patient records were reviewed against the guideline. Antifungal consumption and mortality data were analysed. Results The number of patients treated for invasive candidosis decreased from 39 in 2014 to 29 in 2016. This was mainly due to the reduction in patients initiated on antifungal therapy inappropriately: 18 in 2014 and 2 in 2016. Antifungal therapy was stopped following negative biomarker results in 12 patients in 2014 and 10 patients in 2016. Crude mortality due to proven or probable invasive candidosis decreased to 19% from 45% over the period 2003-07. Antifungal consumption reduced by 49% from 2014 to 2016. Conclusions The AFS programme was successful in reducing the number of inappropriate initiations of antifungals by 90%. Concurrently, mortality due to invasive candidosis was reduced by 58%. BDG testing can guide safe cessation of antifungals in ICU patients at risk of invasive candidosis.

Abstract
BACKGROUND Recent outbreaks of Candida auris further exemplify that invasive Candida infections are a substantial threat to patients and healthcare systems. Even short treatment delays are associated with higher mortality rates. Epidemiological shifts towards more resistant Candida spp. require careful surveillance. OBJECTIVES Triggered by the emergence of C auris and by increasing antifungal resistance rates the European Confederation of Medical Mycology developed an international Candida Registry (FungiScope™ CandiReg) to allow contemporary multinational surveillance. METHODS CandiReg serves as platform for international cooperation to enhance research regarding invasive Candida infections. CandiReg uses the General Data Protection Regulation compliant data platform ClinicalSurveys.net that holds the electronic case report forms (eCRF). Data entry is supported via an interactive macro created by the software that can be accessed via any Internet browser. RESULTS CandiReg provides an eCRF for invasive Candida infections that can be used for a variety of studies from cohort studies on attributable mortality to evaluations of guideline adherence, offering to the investigators of the 28 ECMM member countries the opportunity to document their cases of invasive Candida infection. CandiReg allows the monitoring of epidemiology of invasive Candida infections, including monitoring of multinational outbreaks. Here, we describe the structure and management of the CandiReg platform. CONCLUSION CandiReg supports the collection of clinical information and isolates to improve the knowledge on epidemiology and eventually to improve management of invasive Candida infections. CandiReg promotes international collaboration, improving the availability and quality of evidence on invasive Candida infection and contributes to improved patient management.

Abstract
Pulmonary cryptococcosis is an important opportunistic invasive mycosis in immunocompromised patients, but it is also increasingly seen in immunocompetent patients. The main human pathogens are Cryptococcus neoformans and C. gattii, which have a worldwide distribution. In contrast to cryptococcal meningitis, pulmonary cryptococcosis is still underdiagnosed because of limitations in diagnostic tools. It can mimic lung cancer, pulmonary tuberculosis, bacterial pneumonia, and other pulmonary mycoses both clinically and radiologically. Pulmonary nodules are the most common radiological feature, but these are not specific to pulmonary cryptococcosis. The sensitivity of culture of respiratory samples for Cryptococcus is poor and a positive result may also reflect colonisation. Cryptococcal antigen (CrAg) with lateral flow device is a fast and sensitive test and widely used on serum and cerebrospinal fluid, but sera from patients with pulmonary cryptococcosis are rarely positive in the absence of disseminated disease. Detection of CrAg from respiratory specimens might assist the diagnosis of pulmonary cryptococcosis but there are very few data. Molecular detection techniques such as multiplex reverse transcription polymerase chain reaction (RT-PCR) could also provide better sensitivity but these still require validation for respiratory specimens. The first line of treatment for pulmonary cryptococcosis is fluconazole, or amphotericin B and flucytosine for those with central nervous system involvement. Pulmonary cryptococcosis worsens the prognosis of cryptococcal meningitis. In this review, we summarize the biological aspects of Cryptococcus and provide an update on the diagnosis and management of pulmonary cryptococcosis.

Abstract
Background The objective of this study was to assess the cumulative incidence of invasive candidiasis (IC) in intensive care units (ICUs) in Europe. Methods A multinational, multicenter, retrospective study was conducted in 23 ICUs in 9 European countries, representing the first phase of the candidemia/intra-abdominal candidiasis in European ICU project (EUCANDICU). Results During the study period, 570 episodes of ICU-acquired IC were observed, with a cumulative incidence of 7.07 episodes per 1000 ICU admissions, with important between-center variability. Separated, non-mutually exclusive cumulative incidences of candidemia and IAC were 5.52 and 1.84 episodes per 1000 ICU admissions, respectively. Crude 30-day mortality was 42%. Age (odds ratio [OR] 1.04 per year, 95% CI 1.02–1.06, p < 0.001), severe hepatic failure (OR 3.25, 95% 1.31–8.08, p 0.011), SOFA score at the onset of IC (OR 1.11 per point, 95% CI 1.04–1.17, p 0.001), and septic shock (OR 2.12, 95% CI 1.24–3.63, p 0.006) were associated with increased 30-day mortality in a secondary, exploratory analysis. Conclusions The cumulative incidence of IC in 23 European ICUs was 7.07 episodes per 1000 ICU admissions. Future in-depth analyses will allow explaining part of the observed between-center variability, with the ultimate aim of helping to improve local infection control and antifungal stewardship projects and interventions.

Abstract
BACKGROUND Long-term oral triazole antifungal therapy is the cornerstone of management for patients with chronic pulmonary aspergillosis (CPA). Itraconazole is the first-line choice of treatment. Voriconazole, posaconazole or isavuconazole can be used as alternative treatments in case of resistance or intolerance. All of these can cause significant adverse drug reactions. OBJECTIVES To evaluate how CPA patients tolerate voriconazole and isavuconazole after prior triazole therapy. METHODS We performed a retrospective observational study at the UK National Aspergillosis Centre. Medical records for all consecutive CPA patients started on isavuconazole and voriconazole during an observation period of 12 and 6 months respectively were analysed. RESULTS During this study period, 20 patients were started on isavuconazole and 21 patients on voriconazole. Adverse events were seen in 18 of 21 (86%) the patients in the voriconazole group and 12 of 20 (60%) in the isavuconazole group (P = 0.02). For those who developed adverse events to these agents, the rates of discontinuation of therapy were comparable (ie 10/18 [56%], voriconazole vs 8/12 [67%], isavuconazole; P = 0.54). Five (25%) patients in the isavuconazole group who were intolerant to other triazoles tolerated the standard dose of isavuconazole. CONCLUSIONS Compared with isavuconazole, adverse events were significantly higher in CPA patients commenced on voriconazole. Isavuconazole may be an option for those patients who are intolerant to other triazoles.

Abstract
Aspergillus conida are ubiquitous in the environment, including freshwater, water for bathing, and in drinking water. Vulnerable patients and those suffering from allergic diseases are susceptible to aspergillosis. Avoidance of Aspergillus is of paramount importance. Potential outbreaks of aspergillosis in hospital facilities have been described where the water supply has been implicated. Little is known regarding the risk of exposure to Aspergillus in water. How does Aspergillus survive in water? This review explores the biofilm state of Aspergillus growth based on recent literature and suggests that biofilms are responsible for the persistence of Aspergillus in domestic and healthcare facilities' water supplies.

Abstract
Recurrent vulvovaginal candidiasis is a debilitating, long-term condition that can severely affect the quality of life of affected women. No estimates of the global prevalence or lifetime incidence of this disease have been reported. For this systematic review, we searched PubMed, Embase, and Web of Science databases for population-based studies published between 1985 and 2016 that reported on the prevalence of recurrent vulvovaginal candidiasis, defined as four or more episodes of the infection every year. We identified 489 unique articles, of which eight were included, consisting of 17 365 patients from 11 countries. We generated estimates of annual global prevalence, estimated lifetime incidence and economic loss due to recurrent vulvovaginal candidiasis, and predicted the number of women at risk to 2030. Worldwide, recurrent vulvovaginal candidiasis affects about 138 million women annually (range 103-172 million), with a global annual prevalence of 3871 per 100 000 women; 372 million women are affected by recurrent vulvovaginal candidiasis over their lifetime. The 25-34 year age group has the highest prevalence (9%). By 2030, the population of women with recurrent vulvovaginal candidiasis each year is estimated to increase to almost 158 million, resulting in 20 240 664 extra cases with current trends using base case estimates in parallel with an estimated growth in females from 3·34 billion to 4·181 billion. In high-income countries, the economic burden from lost productivity could be up to US$14·39 billion annually. The high prevalence, substantial morbidity, and economic losses of recurrent vulvovaginal candidiasis require better solutions and improved quality of care for affected women.

Abstract
Candida auris has emerged as a significant global nosocomial pathogen. This is primarily due to its antifungal resistance profile but also its capacity to form adherent biofilm communities on a range of clinically important substrates. While we have a comprehensive understanding of how other Candida species resist and respond to antifungal challenge within the sessile phenotype, our current understanding of C. auris biofilm-mediated resistance is lacking. In this study, we are the first to perform transcriptomic analysis of temporally developing C. auris biofilms, which were shown to exhibit phase- and antifungal class-dependent resistance profiles. A de novo transcriptome assembly was performed, where sequenced sample reads were assembled into an ~11.5-Mb transcriptome consisting of 5,848 genes. Differential expression (DE) analysis demonstrated that 791 and 464 genes were upregulated in biofilm formation and planktonic cells, respectively, with a minimum 2-fold change. Adhesin-related glycosylphosphatidylinositol (GPI)-anchored cell wall genes were upregulated at all time points of biofilm formation. As the biofilm developed into intermediate and mature stages, a number of genes encoding efflux pumps were upregulated, including ATP-binding cassette (ABC) and major facilitator superfamily (MFS) transporters. When we assessed efflux pump activity biochemically, biofilm efflux was greater than that of planktonic cells at 12 and 24 h. When these were inhibited, fluconazole sensitivity was enhanced 4- to 16-fold. This study demonstrates the importance of efflux-mediated resistance within complex C. auris communities and may explain the resistance of C. auris to a range of antimicrobial agents within the hospital environment.IMPORTANCE Fungal infections represent an important cause of human morbidity and mortality, particularly if the fungi adhere to and grow on both biological and inanimate surfaces as communities of cells (biofilms). Recently, a previously unrecognized yeast, Candida auris, has emerged globally that has led to widespread concern due to the difficulty in treating it with existing antifungal agents. Alarmingly, it is also able to grow as a biofilm that is highly resistant to antifungal agents, yet we are unclear about how it does this. Here, we used a molecular approach to investigate the genes that are important in causing the cells to be resistant within the biofilm. The work provides significant insights into the importance of efflux pumps, which actively pump out toxic antifungal drugs and therefore enhance fungal survival within a variety of harsh environments.

Abstract
OBJECTIVES To determine the frequency of oral infection with potential for spread (OIPS) and behavioural risk factors in patients referred to a regional tertiary care-centre for OIPS assessment and clearance. MATERIALS AND METHODS A database search of all referrals to the Oral and Maxillofacial Diseases unit of HUH in 2009 was performed. Of the 2807 referrals, 408 were due to a known or suspected OIPS. The electronic patient records of these patients were analysed for patient demographics, lifestyle factors, radiological findings and clinical oral findings. Risk factors for OIPS were analysed using logistic regression and using the significant factors in univariate analyses in the multivariate models. RESULTS The mean age of the patients was 58 years. Most patients (n = 270, 66%) were referred due to upcoming cancer or other immunosuppressive therapy. The majority (n = 314, 77%) were diagnosed with one or more OIPS. In univariate analyses, smoking (OR 3.2, 95% CI 1.6-6.4; p = 0.0006), male gender (OR 1.7, 95% CI 1.1-2.8; p = 0.02), excessive alcohol use (OR 3.0, 95% 1.1-7.9; p = 0.03) and irregular dental care (OR 4.8, 95% CI 2.6-8.8; p < 0.0001) were risk factors for OIPS. However, in multivariate analyses, smoking was the only independent risk factor for OIPS (OR 3.6, 95% CI 1.2-11.8; p = 0.02). CONCLUSIONS OIPS are common in patients referred for OIPS clearance, and smoking was identified as an independent behavioural risk factor for them. These findings highlight the burden of disease in this patient group and the importance of smoking cessation encouragement. CLINICAL RELEVANCE To identify patients at increased risk of OIPS.

Abstract
Background Urogenital atrophy (UA) is a common treatment-limiting side effect of endocrine therapies. Topical estrogen is effective but systemic absorption may counter aromatase inhibitor efficacy. Numerous complementary approaches are marketed for use in UA without rigorous testing of their estrogenicity. We tested multiple essential oils in cancer cell growth and estrogen reporter assays in vitro and assessed clinical outcomes with the essential oil pessaries (EOPs) in breast cancer survivors with UA. Methods Effects on cell growth were tested in hormone-dependent (MCF-7) and -independent (MDA-MB-231) cell lines using the sulforhodamine-B assay. An estrogen response element (ERE) luciferase reporter assay was used to assess estrogenicity directly. Antifungal activity against two common pathogenic yeasts was assessed using standard microdilution methods. EOPs were offered to breast cancer survivors with symptomatic UA and the service evaluated using serial questionnaires. Results Two essential oils, Cymbopogon martinii and Pelargonium graveolens, demonstrated marked estrogenicity, stimulating ER+ cell growth and ERE-luciferase reporter activity to levels seen with premenopausal estradiol concentrations. Additional oils were screened for estrogenicity and Lavandula angustifolia and Chamaemelum nobile identified as non/minimally estrogenic. The antifungal activity of this combination of oils was confirmed. A second cohort of breast cancer survivors with UA received the second generation EOP with comparable improvement in symptom scores suggesting that estrogenicity may not be required for optimal therapy of UA. Conclusion Certain essential oils demonstrate profound estrogenicity and caution should be exercised before their use in breast cancer survivors. Our minimally estrogenic pessary will be formally tested in clinical trials.

Abstract
Candida species frequently cause blood stream infections and are reported to be the third to tenth most commonly isolated pathogens. Guidelines and standardised treatment algorithms provided by professional organisations aim to facilitate decision-making regarding diagnosis, management and treatment of candidaemia. In routine clinical practise, however, it may be challenging to comply with these guidelines. The reasons include lack of familiarity or feasibility to adherence, but also their length and complexity. There is no tool to measure guideline adherence currently. To provide such a tool, we reviewed the current guidelines provided by the European Society for Clinical Microbiology and Infectious Diseases (ESCMID) and by the Infectious Diseases Society of America (IDSA), and selected the strongest recommendations for management quality as the bases for our scoring tool. Factors incorporated were diagnostic (blood cultures, echocardiography, ophthalmoscopy, species identification) and follow-up procedures (repeat blood cultures until negative result) as well as key treatment parameters (echinocandin treatment, step down to fluconazole depending on susceptibility result, CVC removal). The EQUAL Candida Score weighs and aggregates factors recommended for the ideal management of candidaemia and provides a tool for antifungal stewardship as well as for measuring guideline adherence.
