Abstract
INTRODUCTION Chronic recurrent cystitis (CRC) is a complex multifaceted problem of modern uroinfectology. OBJECTIVE To study the immunological parameters of urine in patients with chronic recurrent cystitis depending on the etiological factor. MATERIALS AND METHODS The prospective study included 71 patients aged 20-45 years who had previously been diagnosed with recurrent lower urinary tract infection: chronic recurrent cystitis (CRC) during an exacerbation period. Based on the results of bacteriological and PCR studies of urine, scraping of the urethra and vagina, depending on the dominant etiological factor, the patients were divided into three groups: group 1 (n=30) - with papillomavirus CRC (PVI-CRC), group 2 (n=30) - with bacterial CRC (B - CRC), group 3 (n=11) - with candida CRC (C - CRC). Analysis of the assessment of immunological parameters of urine was carried out using an enzyme-linked immunosorbent assay (ELISA-BEST). RESULTS Based on the results of an immunological study of urine in the study groups, characteristic specific changes in the level of interleukins and interferons were identified, which made it possible to determine a protocol for the differential diagnosis of CRC. CONCLUSIONS Our study shows the advisability of testing interleukins in urine (IL-1 beta, IL-6, IL-8); these indicators can serve as scoring criteria in the differential diagnosis of CRC of various origins. CONCLUSIONS , it is reasonable to study the level of IFN-2b and IFN; when identifying the functional inferiority of the IFN system in women with CRC, correction of the IFN system is necessary.

Abstract
With rates of ECMO utilization on the rise, prevention of nosocomial infections is of paramount importance. Candida auris, an emerging highly pathogenic multidrug resistant fungus, is of particular concern as it is associated with persistent colonization of environmental surfaces, inability to be recognized by many diagnostic platforms, inconsistent laboratory susceptibility results, and high mortality rates. We describe a case of C. auris in a VV-ECMO patient successfully managed with a combination of anidulafungin, amphotericin B, and flucytosine.

Abstract
Aim This research was done to analyze the effectiveness related to herbal chemicals in tackling candidiasis. Materials and Methods Grounded and ethanol-extracted residues of plants like Avicennia marina, Fagonia indica, Portulaca oleracea, Lawsania inermis, Ziziphus spina, Asphodelus tenuifolius, and Salvadora persica were used in the study. The extract was used against candida species, after which the antibacterial as well as cytotoxicity toward the former were evaluated. Results L. inermis and P. oleracea with minimal inhibitory concentration of approx. 10 cenmL had an increased activity against candida species. The preparations of these plants acted against Candida albicans during its stages related to pathogenesis during biofilm production. Superadded infections like in case of bacterial infections along with candida can be difficult to cure. On human RBCs, these plant preparations had no toxicity at their minimum inhibitory concentration level. Conclusion We concluded that, as far as being anti-candida and acting against MDR bacterial infections, preparations of plants were effective as an alternative to allopathic drugs.

Abstract
This study aimed to design a new Benzydamine HCl (BNZ) suppo-sponge for controlled, mucoadhesive dosage form for vaginal candidiasis treatment, offering advantages over traditional creams, ointments, or gels. BNZ-loaded suppo-sponges were fabricated by simple casting / freeze-drying technique utilizing the cross-linking of chitosan (Cs) with vanillin (V). Vaginal suppo-sponges were prepared based on different vanillin cross-linking ratios (V).n), from 0 to 2%w/w. To best of our knowledge, this is the first study that uses Schiff's base between chitosan and vanillin as a drug delivery system to treat fungal vaginal infections. Schiff's base formation was confirmed by FT-IR. In-vitro appraisal showed acceptable physical and mechanical characteristics. Formulations based on cross-linking of Cs with V showed a more pronounced in-vitro antifungal activity. In-vitro drug release revealed a prolonged release pattern, becoming more noticeable with the higher cross-linked suppo-sponges (22.34% after 8 h). In-vivo testing of CsV2 suppo-sponge indicated a more pronounced reduction in fungal count than both CsV0 and Tantum® Rosa in the first week, with a peak reduction on day 7 and the 10th and 11th days of the second week. Conclusively, Chitosan/vanillin suppo-sponges represent a promising delivery system for drugs intended for local treatment of vaginal candidiasis. than both CsV0 and Tantum® Rosa in the first week, with a peak reduction on day 7 and the 10th and 11th days of the second week. Conclusively, Chitosan/vanillin suppo-sponges represent a promising delivery system for drugs intended for local treatment of vaginal candidiasis.

Abstract
Esophageal pseudodiverticulosis, a rare condition, involves small sac-like structures in the esophageal wall, stemming from dilated excretory ducts of submucosal glands. While uncommon, it can complicate Candida albicans esophagitis, a yeast infection linked to various clinical issues, including pseudodiverticula formation. This unique association underscores the importance of understanding its clinical implications and optimal management. In this case, a 68-year-old female sought medical attention for dysphagia and recurrent food impaction. The diagnostic journey revealed esophageal pseudodiverticulosis and Candida albicans esophagitis, emphasizing the complexity of esophageal disorders.

Abstract
Introduction The burden of multiple drug resistance in human pathogens has necessitated the search for and development of antimicrobial agents with a wide range of structural classes and potentials to selectively act on the several mechanisms of actions exhibited by the pathogens. However, most synthetic antimicrobial agents have been linked with adverse side effects and high costs, furthering the need to explore more options. Syzygium cumini, Moringa oleifera, and Tinospora cordifolia are three medicinal plants used in traditional medicine systems for various infectious diseases. They contain various phytochemicals that exhibit antimicrobial activities against various bacteria, fungi, and parasites. The mechanisms of their antimicrobial action may involve the disruption of microbial cell walls and membranes, the inhibition of microbial enzyme and biofilm formation, the modulation of microbial gene expression and quorum sensing, and the induction of microbial cell death. Therefore, the present study evaluated the potentials of aqueous and ethanol extracts of S. cumini, M. oleifera, and T. cordifolia in managing infections as measured by their inhibitory effects on species. Materials and method Syzygium cumini, M. oleifera, and T. cordifolia were obtained and authenticated, and their aqueous and ethanol extracts were prepared. The antibacterial properties of the aqueous and ethanol extracts were examined. In addition to broth microdilution and biofilm development experiments, we also employed disk diffusion and agar-well diffusion techniques. The inocula of various species, including krusei, parapsilosis, utilis, albicans, and glabrata, were prepared for these assays. The synergistic effect of plant extracts with fluconazole was also evaluated. Results Syzygium cumini, M. oleifera, and T. cordifolia emerge as promising sources for the development of effective and sustainable antimicrobial interventions. Interestingly, the aqueous and ethanol extracts were effective against the selected species. Also, the synergistic combination of plant extracts with fluconazole was observed to triple the potency of the extracts. Furthermore, the potency of the plant extract as an antifungal and synergistic agent was ranked as S. cumini > M. oleifera > T. cordifolia. Conclusively, the plant extracts are effective in the management of opportunistic fungal infections.

Abstract
BACKGROUND Candida auris is an emerging multidrug-resistant fungal pathogen that represents a current serious threat to healthcare settings. OBJECTIVE The objective was to determine the prevalence of C. auris in a Riyadh hospital since its initial detection in late 2019. METHODS Using an adapted risk assessment tool, we reviewed the charts and medical files of all suspected and confirmed cases of C. auris infections reported at King Khalid University Hospital, Riyadh, between November 2019 and December 2022. Anonymized data were retrieved in a pre-established datasheet and analyzed to determine the epidemiological characteristics of C. auris infections in our facility. We analyzed prevalence by age, gender, risk factors, and according to sampling source. RESULTS Of the 53 confirmed C. auris-positive cases during the study period, 33 (62%) were males. Their ages ranged between 15 and 98, with most positive cases occurring in those aged 50 and above. Only one of the confirmed cases was hospital-acquired. All patients had at least one risk factor, and urine samples yielded the greatest number of positive cases, while admission to healthcare facilities constituted the highest risk in our study. CONCLUSION Establishing a local prevalence pattern could serve as a baseline/benchmark to compare with regional and international benchmarks.

Abstract
BACKGROUND Fungal prosthetic joint infections (PJIs) after a total joint arthroplasty are a rare, yet severe, occurrence not often reported in the literature. Unlike in bacterial PJIs, no clear consensus exists on fungal PJI optimal management. METHODS A systematic review was performed using the PubMed and Embase databases. Manuscripts were assessed for inclusion and exclusion criteria. The Strengthening the Reporting of Observational Studies in Epidemiology checklist was applied for quality assessment. Individual demographic, clinical, and treatment information was retrieved from included manuscripts. RESULTS Seventy one patients who had a PJI of the hip and 126 of the knee were included. Infection recurrence occurred in 29.6% and 18.3% of patients with hip or knee PJI, respectively. Patients who had knee PJIs recurrence had a significantly higher Charlson Comorbidity Index (CCI). For knee PJIs, infection recurrence was more common in patients with Candida albicans (CA) PJIs (P = .022). Two-stage exchange arthroplasty was the most common procedure in both joints. Multivariate analysis found that CCI ≥ 3 was associated with an 18.5-fold increase in the risk of knee PJI recurrence (Odds ratio [OR] = 18.57). Additional risk factors for recurrence in the knee included CA etiology (OR = 3.56) and C-reactive protein at presentation ≥ 6 (OR = 6.54). Compared to debridement, antibiotics, and implant retention, 2-stage procedure was a protective factor for PJI recurrence in the knee (OR = 0.18). No risk factors were found in patients who had hip PJIs. CONCLUSION Treatment of fungal PJIs varies widely, but 2-stage revision is the most common. Risk factors for knee fungal PJI recurrence include elevated CCI, infection by CA, and high C-reactive protein at presentation.

Abstract
In this unique cytology case of a 64-year-old diabetic male who presented with left-sided facial swelling between the ala and lateral canthus of the left eye, conventional fine-needle aspiration cytology (FNAC) was done. FNAC of the swelling showed desquamated epithelial cells from the nasolacrimal duct and abundant proteinaceous material admixed with fungal organisms like that of budding yeast forms, morphologically resembling Candida on May-Grunwald-Giemsa stain. Special stain with periodic acid-Schiff revealed positivity for budding yeast forms. In this case report, we discuss the causes and clinical effects of nasolacrimal duct obstruction, cytological diagnostic features, and microscopic recognition of fungal organisms on routine staining as well as on special fungal stains.

Abstract
Esophageal candidiasis is the most common infectious disease of the esophagus. The diagnosis is based on gastroscopy, and in many cases, biopsy samples should be taken as well. If we do not know of any risk factors for an immunocompromised condition, it is a mutual responsibility to confirm or exclude any potential chronic disease in the background, thus not just the secondary complication but also the primary disease could be treated. Without this knowledge, in many cases, the correct diagnosis may be delayed for months or even years, which may risk the successful treatment. We present the case of a 58-year-old healthy woman without any chronic disease, who was referred to our clinic with dysphagia. Due to her complaints we performed a gastroscopy, upon which advanced esophageal candidiasis was diagnosed, hence she was started on oral systemic antifungal treatment. Although we could not explore any risk factors, further investigations behind the immunocompromised condition revealed a positive immunoserology test for HIV. The take-home message of our case is that in the case of esophageal candidiasis, the cause of immunosuppression must be searched for, of which HIV serology is crucial. Thanks to the prompt and correct diagnosis, we could start the suitable treatment of the underlying disease. Orv Hetil. 2023; 164(22): 878-880.

Abstract
A variety of Candida spp. can be found as a natural commensal fungus in various parts of the human body. This fungus may be associated with various diseases such as celiac disease (CD). Gliadin, a component of the gluten protein complex that is mostly found in wheat, is the main inducer of CD. A number of studies have demonstrated that patients infected with Candida can develop CD, and vice versa. C. albicansis presumed to induce CD because it has a protein homologous to gliadin in its cell wall called Hwp1. Despite the non-specificity of the anti-gliadin test, the detection of antibodies against anti-gliadin (AGA) and anti-tissue transglutaminase (anti-tTG) are important in the diagnosis of CD. Some evidence is now available to support the hypothetical correlation between Candida spp. and CD, as high levels of AGA have been found in patients infected with candidiasis without CD. Further study is needed to confirm this relationship.

Abstract
INTRODUCTION A diagnosis and treatment of recurrent lower urinary tract infection (UTI) in women is still one of the unresolved problems of urology. The proper identification of the etiological factor determines the treatment tactics. Therefore, the most urgent issue of recurrent lower UTI is the differential diagnosis of the causative pathogens. MATERIALS AND METHODS A cytological study of urine was performed in 151 patients with recurrent lower UTI, who, according to the results of bacteriological and PCR studies of urine, were divided into three groups, depending on the etiological factor. The group 1 (n=70) included women with recurrent lower UTI of bacterial etiology, while in group 2 (n= 70) papillomavirus etiology was found, and in group 3 (n=11) candida species were the causative pathogens. The age of the patients ranged from 20 to 45 years (32.3+/-7.8). RESULTS In the majority of patients with recurrent lower UTI of bacterial etiology, the cytological features were represented by leukocytes, plasma, epithelial cells and bacteria in combination with actively phagocytic macrophages. In group 3, in addition to a large number of leukocytes (neutrophils) and epithelial cells, Candida mycelium was found. In group 2, signs of bacterial inflammation were minimal, while a predominance of lymphocytes, epithelial cells, and the presence of single neutrophils was seen. With papillomavirus lesions of the bladder, urothelial cell dystrophy with the presence of koilocytes developed. CONCLUSIONS A cytological examination of urine can confirm the etiology of the recurrent lower UTI and be an evidence-based criterion in the differential diagnosis of bacterial, candidiasis, and papillomavirus infection. Total transformation of the urothelium and vacuolization of urothelial cells, as well as an excess of lymphocytes in the urine in the absence of neutrophils, are the characteristic features of viral recurrent lower UTI.

Abstract
Infective endocarditis (IE) carries high morbidity and mortality. Although minimal in incidence, fungal causes (mostly Candida species) carry the highest mortality among all cases of infective endocarditis. We describe a rare case of a 47-year-old male with a past medical history of cerebral vascular accident (CVA), heart failure with reduced ejection fraction status post (SP) automated implantable cardioverter defibrillator (AICD) placement, paroxysmal atrial fibrillation, coronary artery disease (CAD), infective endocarditis with mitral valve replacement and tricuspid valve replacement, and pulmonary hypertension who presented to the emergency department (ED) with complaints of shortness of breath and weakness for four days. The patient was admitted to the cardiac care unit (CCU) due to persistent hypotension despite being on a continuous milrinone drip at home. The patient was initially started on antimicrobial agents for sepsis most likely secondary to pneumonia. Echocardiographic imaging showed a large vegetation on the tricuspid valve; hence, blood cultures were sent and came back positive for Candida sp. Appropriate antifungals (micafungin) were added to the medication regimen, and the patient was transferred to a tertiary hospital for surgical intervention. Patients with bioprosthetic valve replacement require regular follow-ups as this would allow providers to catch symptoms of developing endocarditis and prevent disease progression. These appointments may also decrease other risk factors for the disease, including but not limited to infected lines.

Abstract
Time-to-positivity (TTP) may assist in predicting outcome of candidaemia. We analysed a candidaemia dataset collected prospectively in Australia over 1 year (2014-2015). Time to positivity was defined as the period from blood culture sampling to the blood culture flagging positive. Of 415 candidaemia episodes, overall 30-day mortality was 29% (120/415); mortality with Candida albicans was 35% (59/169), C. glabrata complex, 37% (43/115), C. tropicalis, 43% (10/23), Pichia kudriavzevii 25% (3/12) and C. parapsilosis complex 7% (5/71). Each day of increased TTP multiplied the odds ratio (OR) of survival at 30 days by a factor of 1.32 (95%CI 1.06-1.69). Shorter TTP was associated with increased mortality, with 1 day TTP associated with 30-day mortality 37% (41/112) (95%CI: 28%-46%) and 5-day TTP 11% (2/18) (95%CI: 2%-36%).

Abstract
Introduction Candida species (spp.) are among the leading agents of bloodstream infections. Candidemias are a major cause of morbidity and mortality. Having an understanding of Candida epidemiology and antifungal susceptibility patterns in each center is crucial in guiding the management of candidemia. In this study, the species distribution and antifungal susceptibility of Candida spp. isolated from blood culture at the University of Health Sciences, Bursa Yuksek Ihtisas Training & Research Hospital were examined and the first data on the epidemiology of candidemia in our center were presented. Methods A total of 236 Candida strains isolated from blood cultures in our hospital over a four-year period were analyzed and their antifungal susceptibilities were studied retrospectively. Strains were identified at the species complex (SC) level by the germ tube test, morphology in cornmeal-tween 80 medium, and the automated VITEK 2 Compact (bioMérieux, Marcy-l'Étoile, France) system. Antifungal susceptibility tests were performed on VITEK 2 Compact (bioMérieux, Marcy-l'Étoile, France) system. The susceptibilities of the strains to fluconazole, voriconazole, micafungin, and amphotericin B were determined according to Clinical and Laboratory Standards Institute (CLSI) guidelines and epidemiologic cut-off values. Results Of the Candida (C.) strains, 131 were C. albicans (55.5%), 40 were C. parapsilosis SC (16.9%), 21 were C. tropicalis (8.9%), 19 were C. glabrata SC (8.1%), eight were C. lusitaniae (3.4%), seven were C. kefyr (3.0%), six were C. krusei (2.6%), two were C. guilliermondii (0.8%) and two were C. dubliniensis (0.8%). Amphotericin B resistance was not detected in Candida strains. Micafungin susceptibility was 98.3%, and four C. parapsilosis SC strains (10%) were intermediate (I) to micafungin. Fluconazole susceptibility was 87.2%. Apart from C. krusei strains which intrinsically resistant to fluconazole, three C. parapsilosis (7.5%), one C. glabrata SC (5.3%) strain were resistant (R) to fluconazole, and one C. lusitaniae (12.5%) strain was wild-type (WT). Voriconazole susceptibility of Candida strains was 98.6%. Two C. parapsilosis SC strains were I to voriconazole, while one strain was R. Conclusion In this study, the first epidemiological data of candidemia agents in our hospital were presented. It was determined that rare and naturally resistant species did not cause any problem in our center yet. C. parapsilosis SC strains showed decreased susceptibility to fluconazole, whereas Candida strains were highly susceptible to the four antifungals tested. Close monitoring of these data will help guide the treatment of candidemia.

Abstract
Spondylodiscitis is a pathology with a devastating potential for functional limitation in patients, which may involve immobilization for months due to the risk of compression or even spinal cord section. It is a rare type of infection occurring in the vertebrae and discs of the spine, and most are bacterial. Fungal cases are rare. We present the clinical case of a 52-year-old female patient with a past medical history of vesicular lithiasis and degenerative disc disease of the cervical spine and no home medication. The patient was hospitalized in the surgery service for about 3.5 months due to necro-hemorrhagic lithiasic pancreatitis that evolved into septic shock and needed organ support in intensive care for 2.5 weeks. Several cycles of antibiotics and endoscopic retrograde cholangiopancreatography (ERCP) with stent placement were performed. She was readmitted for urgent care to the hospital of residence with fever, sweating, and low back pain with sciatica five days after discharge. Lumbar CT and MRI evidence showed the destruction of about two-thirds of the vertebral bodies L3-L4, L5-S1, and adjacent discs, pointing to the diagnosis of infectious spondylodiscitis. Candida albicans was found in blood cultures and lumbar biopsies. The patient was treated with oral fluconazole 400 mg/day for eight months, and the control MRIs showed slow but favorable bone sclerosis over time. She spent a total of 13.5 months in the hospital, including five months in bedbound status. The patient left the hospital walking without any assistance, with an upright mood and disposition. The most likely main fungal infectious factors were the manipulation of the bile ducts, immunosuppression associated with corticosteroid therapy, and multiorgan septic failure. The authors highlight this clinical case for its rarity, complications leading to candidemia, diagnostic and therapeutic delay, complexity, and risk of irreversible injuries to which the patient was subjected. The total recuperation of the patient after such a long physical and emotional struggle was very gratifying.

Abstract
Introduction Pulmonary tuberculosis (TB) has long been associated with opportunistic fungal infections and could prove lethal if these fungal infections are not detected in the early stages of tuberculosis. TB patients are mostly immunocompromised, and an association with a fungal infection fuels each other, thus decreasing host immunity and making it difficult to treat. Extensive use of antibiotics and steroids has resulted in increasing trends of these fungal infections globally. Material and methods This observational, retrospective hospital-based medical record review study was conducted in the Department of Microbiology at the Indira Gandhi Institute of Medical Sciences (IGIMS), Patna, Bihar, India. A total of 200 medical records of pulmonary tuberculosis patients diagnosed by using sputum as clinical samples were evaluated and analysed for two years, from January 2020 to December 2021. This study was started after approval from the institutional ethical committee. Data were obtained from the mycology test records from the Department of Microbiology and from the data files of the medical records section over a period of two years. Results Our study included the medical records of 200 pulmonary tuberculosis patients who underwent treatment at IGIMS Patna. Out of 200 patient records, 124 (62%) were males and 76 (38%) were females. The male-to-female ratio was 1.6:1. After analysis and evaluation of 200 medical records of pulmonary tuberculosis patients, fungal species were detected in 16 (8%) sputum samples. Among 16 culture-positive sputum samples, 10 (8.06%) and six (7.1%) were diagnosed in male and female patients, respectively. Fisher's exact test showed a non-significant two-sided p-value of 1.000 with a relative risk of 0.9982. The prevalence, or positivity rate, was 8% in two years. The age group of 31-45 years had the most fungal co-infection at 37.5%. Among the fungal isolates, 5/16 (31.25%) were yeasts, and the remaining 11/16 (68.75%) isolates were mycelial fungi. Conclusion According to the findings of the present study, pulmonary fungal infections co-exist in tuberculosis patients, although the prevalence rates of all the coinfections are low and statistically not significant. Being chronic in nature and with confusing clinical and radiological findings, these fungal infections are misdiagnosed as reactivation of tuberculosis. Hence, the increasing rate of morbidity and mortality can decrease if adequate measures are taken for the diagnosis at an early stage and appropriate treatment of these fungal mycoses with antifungal therapy is instituted.

Abstract
BACKGROUND The incidence of candidemia in severe COVID-19 patients (0.8-14%) is two- to ten-fold higher than in non-COVID-19 patients. METHODS This retrospective analysis aimed to analyse the incidence of bloodstream infections (BSI) due to Candida in a cohort of COVID-19 patients supported with ECMO. RESULTS Among 138 intubated and ventilated patients hospitalized for ≥10 days in the intensive care unit of a teaching hospital, 45 (32.6%) patients received ECMO support, while 93 patients (67.4%) did not meet ECMO criteria and were considered the control group. In the ECMO group, 16 episodes of candidaemia were observed, while only 13 in patients of the control group (36.0% vs. 14.0%, p-value 0.004). It was confirmed at the survival analysis (SHR: 2.86, 95% CI: 1.39-5.88) and at the multivariable analyses (aSHR: 3.91, 95% CI: 1.73-8.86). A higher candida score seemed to increase the hazard for candidemia occurrence (aSHR: 3.04, 95% CI: 2.09-4.42), while vasopressor therapy was negatively associated with the outcome (aSHR: 0.15, 95% CI: 0.05-0.43). CONCLUSIONS This study confirms that the incidence of candidemia was significantly higher in critically ill COVID-19 patients supported with VV-ECMO than in critically ill COVID patients who did not meet criteria for VV-ECMO.

Abstract
Oral lichen planus (OLP) is a chronic inflammatory disease that commonly affects the skin and mucous membranes. There is a difference of opinion among clinicians about whether OLP has been associated with oral candidiasis. Nonetheless, in OLP patients, the oral candidiasis prevalence rate ranges from 7.7 to 16.6%, as established through biopsy findings, whereas 37-50% of the prevalence rate has been noticed in culture findings. Oral candidiasis has been linked to several local and systemic factors, including salivary gland dysfunction, dental prostheses, topical or inhaled corticosteroids, smoking, and the use of systemic medications. The aim was to highlight the association of Candida in patients diagnosed with OLP, correlate the use of steroid therapy, and enumerate the factors of using steroid therapy as implicated causes for oral candidiasis. A search was made using search engines such as PubMed, Scopus, Cochrane Database of Systematic Reviews, Science Citation Index, NIH Public Access, and Clarivate Analytics (Figure 1). The keywords using the research option for this field were "Oral Candidiasis" AND "Oral Lichen planus" or "Candidiasis" AND "Corticosteroids" or "Topical Corticosteroids" AND Oral Lichen planus or "Inhalation Corticosteroids" AND "Candidiasis" or "Oral Lichen planus" AND "Corticosteroids." The database search was made for the duration of 1991 to -2021 (Table 1). Additional articles were obtained regarding the literature on OLP and oral candidiasis and were considered background material. The incidence of oral candidiasis and associated lichen planus following steroid therapy enlisted by various authors has been addressed. According to the results of this study, there is a positive correlation between the presence of oral candidiasis in the OLP's patients treated with corticosteroids. Finally, this meta-analysis concluded that there is a positive correlation between the presence of Candida species in OLP and steroid medication.

Abstract
Background and aims Abnormal vaginal discharge is a prevailing gynecological problem among women in the reproductive age group. Vaginal discharges have multiple etiologies, and the present study was conducted with the objective of determining the prevalence of common organisms causing vaginal discharge and correlating with its various types of clinical presentations in those women attending a rural health centre of a medical college in Tamil Nadu, India. Materials and methods The study was a cross-sectional descriptive study, conducted in a rural health center of a teaching hospital in Tamil Nadu, India, from February 2022 to July 2022. All the patients clinically having the symptoms of vaginitis and with a discharge were included in this study, and postmenopausal women and pregnant women were excluded. Data was collected from a total of 175 patients. Results The mean (SD) age of the study population was 34.8 (6.9) years. Almost half, 91 (52%), of the study participants were in the age group of 31-40 years. Bacterial vaginosis was found in 74 (42.3%) and was the most common cause of abnormal vaginal discharge in our study participants, followed by vulvovaginal candidiasis, 34 (19.4%). There were significant associations between high-risk sexual behavior and the presence of co-morbidities with abnormal vaginal discharge. Conclusion The most common causes of abnormal vaginal discharge were found to be bacterial vaginosis followed by vulvovaginal candidiasis. The study results help to initiate early appropriate treatment for effective management of a community health problem.

Abstract
Candida albicans is a pathobiont that inflicts serious bloodstream fungal infections in individuals with compromised immunity and gut dysbiosis. Genomic diversity in the form of copy number alteration, ploidy variation, and loss of heterozygosity as an adaptive mechanism to adverse environments is frequently observed in C. albicans. Such genomic variations also confer a varied degree of fungal virulence and drug resistance, yet the factors propelling these are not completely understood. DNA polymerase delta (Polδ) is an essential replicative DNA polymerase in the eukaryotic cell and is yet to be characterized in C. albicans. Therefore, this study was designed to gain insights into the role of Polδ, especially its non-essential subunit Pol32, in the genome plasticity and life cycle of C. albicans. PCNA, the DNA clamp, recruits Polδ to the replication fork for processive DNA replication. Unlike in Saccharomyces cerevisiae, the PCNA interaction protein (PIP) motif of CaPol32 is critical for Polδ's activity during DNA replication. Our comparative genetic analyses and whole-genome sequencing of POL32 proficient and deficient C. albicans cells revealed a critical role of Pol32 in DNA replication, cell cycle progression, and genome stability as SNPs, indels, and repeat variations were largely accumulated in pol32 null strain. The loss of pol32 in C. albicans conferred cell wall deformity; Hsp90 mediated azoles resistance, biofilm development, and a complete attenuation of virulence in an animal model of systemic candidiasis. Thus, although Pol32 is dispensable for cell survival, its function is essential for C. albicans pathogenesis; and we discuss its translational implications in antifungal drugs and whole-cell vaccine development.

Abstract
BACKGROUND Matrix-assisted laser desorption/ionisation-time of flight mass spectrometry (MALDI-TOF MS) allows rapid pathogen identification and potentially can be used for antifungal susceptibility testing (AFST). OBJECTIVES We evaluated the performance of the MALDI-TOF MS in assessing azole susceptibility, with reduced incubation time, by comparing the results with the reference method Broth Microdilution. METHODS Resistant and susceptible strains of Candida (n = 15) were evaluated against fluconazole and Aspergillus (n = 15) against itraconazole and voriconazole. Strains were exposed to serial dilutions of the antifungals for 15 h. Microorganisms' protein spectra against all drug concentrations were acquired and used to generate a composite correlation index (CCI) matrix. The comparison of autocorrelations and cross-correlations between spectra facilitated by CCI was used as a similarity parameter between them, enabling the inference of a minimum profile change concentration breakpoint. Results obtained with the different AFST methods were then compared. FINDINGS The overall agreement between methods was 91.11%. Full agreement (100%) was reached for Aspergillus against voriconazole and Candida against fluconazole, and 73.33% of agreement was obtained for Aspergillus against itraconazole. MAIN CONCLUSIONS This study demonstrates MALDI-TOF MS' potential as a reliable and faster alternative for AFST. More studies are necessary for method optimisation and standardisation for clinical routine application.

Abstract
The burden of fungal infections has been on the rise globally and remains a significant public health concern in Kenya. We estimated the incidence and prevalence of fungal infections using all mycology publications in Kenya up to January 2023, and from neighbouring countries where data lacked. We used deterministic modelling using populations at risk to calculate the disease burden. The total burden of serious fungal infections is estimated to affect 6,328,294 persons which translates to 11.57% of the Kenyan population. Those suffering from chronic infections such as chronic pulmonary aspergillosis are estimated to be 100,570 people (0.2% of the population) and probably nearly 200,000 with fungal asthma, all treatable with oral antifungal therapy. Serious acute fungal infections secondary to HIV (cryptococcal meningitis, disseminated histoplasmosis, pneumocystis pneumonia, and mucosal candidiasis) affect 196,543 adults and children (0.4% of the total population), while cancer-related invasive fungal infection cases probably exceed 2,299 and those in intensive care about 1,230 incident cases, including Candida auris bloodstream infection. The burden of fungal infections in Kenya is high; however, limited diagnostic test availability, low clinician awareness and inadequate laboratory capacity constrain the country's health system in responding to the syndemic of fungal disease in Kenya.

Abstract
This study investigated whether sphingosine is effective as prophylaxis against Aspergillus spp. and Candida spp. In vitro experiments showed that sphingosine is very efficacious against A. fumigatus and Nakeomyces glabrataa (formerly named C. glabrata). A mouse model of invasive aspergillosis showed that sphingosine exerts a prophylactic effect and that sphingosine-treated animals exhibit a strong survival advantage after infection. Furthermore, mechanistic studies showed that treatment with sphingosine leads to the early depolarization of the mitochondrial membrane potential (Δψm) and the generation of mitochondrial reactive oxygen species and to a release of cytochrome C within minutes, thereby presumably initiating apoptosis. Because of its very good tolerability and ease of application, inhaled sphingosine should be further developed as a possible prophylactic agent against pulmonary aspergillosis among severely immunocompromised patients.

Abstract
Post-tonsillectomy complications can include bleeding, dehydration, edema, airway obstruction, and infection. Oral candidiasis or thrush is a rare complication that can occur post-operatively. We describe a case of a 10-year-old female with oral candidiasis as a postoperative complication of bilateral adenotonsillectomy, presenting on postoperative day (POD) 7 for poor oral intake secondary to worsening odynophagia. A physical exam revealed an easily scrapable, white plaque located mainly over her surgical sites, tongue, and hard palate. Microscopic examination of tissue scrapings revealed pseudohyphae confirming the diagnosis of oral candidiasis. She was treated with seven days of topical nystatin therapy, including topical and systemic pain control with significant improvement of symptoms by POD 13 and complete resolution on POD 21.

Abstract
PURPOSE To describe the demographic clinical characteristics and to identify the risk factors of patients diagnosed with fungemia and secondary intraocular involvement. METHODS Retrospective cohort of 97 patients diagnosed with fungemia and with or without involvement of the posterior segment. Demographic, clinical and ophthalmological variables were identified to establish the risk of retinal seeding. RESULTS An incidence of ocular involvement of 22.68% was obtained and no clear risk factor was found for subsequent showings in patients with fungemia. A risk trend was only found in patients with diabetes with an OR: 2.85; CI 95%: (0.80-10.12) and history of HIV with an OR: 2.29 CI95%: (0.85-6.12). CONCLUSIONS In this first cohort carried out in Colombia according to our search, findings were obtained that agree with those of other authors worldwide, where there is no evidence of a decrease in incidence compared with older studies and the absence of risk factors for the compromise of the posterior pole in patients with fungemia.KEY MESSAGESSystematic fundus evaluation by an ophthalmologist in patients with candidaemia is a recommended practice based on low-quality evidence.The identification of real risk factors for retinal compromise in fungemia would allow us to be more selective with the population to be evaluated.Fungemia generally occurs in critically ill patients, where access and availability of ophthalmology evaluation are a resource that is not always available.

Abstract
Fungal lung co-infections associated with COVID-19 may occur in severely ill patients or those with underlying co-morbidities, and immunosuppression. The most common invasive fungal infections are caused by aspergillosis, mucormycosis, pneumocystis, cryptococcus, and candida. Radiologists integrate the clinical disease features with the CT pattern-based approach and play a crucial role in identifying these co-infections in COVID-19 to assist clinicians to make a confident diagnosis, initiate treatment and prevent complications.

Abstract
BACKGROUND The development of candidemia is a highly fatal condition in severe COVID-19 infection. OBJECTIVES This study aimed to develop a candidemia prediction score in COVID-19 patient based on the patient's clinical characteristics, and healthcare-related factors during intensive care units (ICU) follow-up. PATIENTS/METHODS Severe COVID-19 patients hospitalised in ICU in Ankara City Hospital during the one-year period (August 15, 2020, and August 15, 2021) were included. After univariate analysis, multivariate analysis was applied using variable selection approach to investigate the effects of variables together and to create a score model for candidemia. Statistically significant factors were included in the development process of candida prediction score. RESULTS Of 1305 COVID-19 ICU patients, 139 had a candidemia episode. According to the final model, four variables, presence of central venous catheter (CVC) (OR 19.07, CI 8.12-44.8, p < .0001), multifocal colonisation (OR 2.28, CI 1.39-3.72, p 0.001), length of ICU stays ≥14 days (OR 3.62, CI 2.42-5.44, p < .0001) and corticosteroids (OR 0.51, CI 0.34-0.76, p 0.0011) were the only statistically significant independent risk factors for candidemia. Score model was demonstrated by a nomogram, and the risk for candidemia was calculated to be high in patients who scored ≥56 points by using the criteria [CVC = 51, multifocal colonisation = 14, prolonged hospitalisation = 23, no steroid use = 12 points]. The AUC of the score is 0.84 (CI 0.81-0.87). CONCLUSION We developed and validated an easy-to-use clinical prediction score for candidemia in severe COVID-19 infection. In COVID-19 ICU patients, the risk of candidemia is high if one of the other risk factors is present together with CVC.

Abstract
INTRODUCTION Despite the availability of novel antifungals and therapeutic strategies, the rate of global mortality linked to invasive fungal diseases from fungal infection remains high. Candida albicans account for the most invasive mycosis produced by yeast. Thus, the current arsenal of medicinal chemists is focused on finding new effective agents with lower toxicity and broad-spectrum activity. In this review article, recent efforts to find effective agents against azole-resistant candidiasis, a common fungal infection, are covered. AREAS COVERED Herein, the authors outlined all azole-based compounds, dual target, and new scaffolds (non-azole-based compounds) which were effective against azole-resistant candidiasis. In addition, the mechanism of action and SAR studies were also discussed, if the data were available. EXPERT OPINION The current status of fungal infections and the drawbacks of existing drugs have encouraged scientists to find novel scaffolds based on different methods like virtual screening and fragment-based drug discovery. Machine learning and in-silico methods have found their role in this field and experts are hopeful to find novel scaffolds/compounds by using these methods.

Abstract
INTRODUCTION Multi-organ dysfunction caused by thromboembolic complications may complicate the course of SARS-CoV-2 infection. Most patients require anticoagulant therapy which predisposes them to the development of hemorrhagic syndrome. In critically ill COVID-19 patients secondary infections due to opportunistic pathogens are associated with a high mortality rate. CASE REPORT Herein, we present a COVID-19 patient with severe hemorrhage at unusual sites complicated with invasive candidiasis and an extensively drug-resistant (XDR) strain of Klebsiella enterobacter. CONCLUSIONS Clinicians should be aware of the possibility for invasive fungal infections in severely ill patients with SARS-CoV-2 infection due to pre-existing conditions, risk factors, and COVID-19 associated pathological mechanisms. Management of invasive candidiasis is challenging because of the high prevalence of comorbidities, risk of toxicities, and drug interactions.

Abstract
The epidemiology of fungal infections in Eritrea is unknown. Most cases are under‐reported due to a lack of diagnostics. This study estimates the burden of serious fungal infections and highlights treatment and diagnostic gaps in the country. All publications related to fungal infections were identified by searches using PubMed/Medline and Google Scholar. Where no data were available, data from neighbouring countries, then sub‐Saharan African countries, then other parts of the world were considered for deriving estimates. The Eritrea population was 3,546,427 in 2020. In 2020, HIV/AIDS patients numbered 1400 and TB incidence were 2875. The five‐year adult prevalence of asthma (2016–2020) was 41,390, and the total prevalence estimate of chronic obstructive pulmonary disease (COPD) was 308,328. The annual incidence of cryptococcal meningitis and Pneumocystis jirovecii pneumonia in AIDS patients was estimated at 96 and 205 cases. Oesophageal candidiasis incidence is 715 HIV‐infected patients. Chronic pulmonary aspergillosis prevalence, including post‐tuberculosis cases, was estimated at 1399 (39/100,000). Fungal asthma has a prevalence of 1035 and 1366 in adults. The estimated prevalence of recurrent vulvovaginal candidiasis and tinea capitis is 59,391 and 342,585, respectively. There are no data on candidaemia, but it is estimated at 5/100,000 (177 cases annually). Invasive aspergillosis in leukaemia, lung cancer, COPD and HIV is estimated at 540 cases and fungal keratitis in 514 cases annually. Serious fungal infections are prevalent in Eritrea with approximately 408,164 people (11.5%) affected annually. Studies on fungal diseases to improve diagnosis and treatment are required with the implementation of a national surveillance program.

Abstract
BACKGROUND Critically ill COVID-19 patients have a high risk for the development of candidemia due to being exposed to both well-defined classical risk factors and COVID-19-specific risk factors in ICU. OBJECTIVES In this study, we investigated the incidence of candidemia in critically COVID-19 patients, and the independent risk factors for candidemia. PATIENTS/METHODS COVID-19 patients hospitalised in ICU during 1-year period (August 2020 to August 2021) were included. Clinical and laboratory characteristics of all COVID-19 patients, applied treatments, and invasive procedures that may predispose to candidemia were recorded. RESULTS Of 1229 COVID-19 patients, 63 developed candidemia. Candidemia incidence rate was 4.4 episodes per 1000 ICU days. The most common species was Candida albicans (52.3%). Only 37 patients (58.7%) received antifungal therapy. The presence of central venous catheter (OR 4.7, 95% CI 1.8-12.2, p < .005), multifocal candida colonisation (OR 2.7, 95% CI 1.4-5.2, p < .005), a prolonged ICU stay (≥14 days) (OR 1.9, 95% CI 1.08-3-37, p < .05), the absence of chronic lung disease (OR 0.4, 95% CI 0.1-0.9, p < .05) and the absence of corticosteroid use (OR 0.3, 95% CI 0.14-0.52, p < .0001) were significantly associated with candidemia. CONCLUSIONS Our study filled the knowledge gap in the literature about the impact of COVID-19-associated risk factors for the development of candidemia. The classical risk factors for candidemia had a significant effect on candidemia, and contrary to expectations, corticosteroids had a protective effect against the development of candidemia. The results of these studies showing interesting effects of corticosteroids in critically ill COVID-19 patients should be confirmed by further studies.

Abstract
AbstractPilzinfektionen, die durch Candida‐Arten verursacht werden, gehören zu den häufigsten Infektionen bei Krankenhauspatienten. Die derzeitigen Methoden zum Nachweis von Candida‐Pilzzellen in klinischen Proben beruhen jedoch auf zeitaufwändigen Analysen, die eine schnelle und zuverlässige Diagnose erschweren. In diesem Beitrag beschreiben wir die rationale Entwicklung neuer Phe‐BODIPY‐Aminosäuren als kleine fluorogene Bausteine und ihre Anwendung zur Erzeugung fluoreszierender antimikrobieller Peptide für die schnelle Markierung von Candida‐Zellen im Urin. Mit Hilfe von computergestützten Berechnungen haben wir das fluorogene Verhalten von BODIPY‐substituierten aromatischen Aminosäuren analysiert und Bioaktivitäts‐ und konfokale Mikroskopieexperimente bei verschiedenen Stämmen durchgeführt, um den Nutzen und die Vielseitigkeit von Peptiden mit Phe‐BODIPYs zu bestätigen. Schließlich haben wir einen einfachen und sensitiven fluoreszensbasierten Test zum Nachweis von Candida albicans in menschlichen Urinproben entwickelt.

Abstract
Purpose To report the management of a case of candida endophthalmitis following
intubation for SARS-CoV-2 ARDS, during the first lockdown, underlining
consequently the limited access to the gold standard of care. Methods Case report. Results We have described the case of a 56-year-old Hispanic man who developed
bilateral Candida endophthalmitis after one month of hospitalization in the
intensive care unit for severe SARS-CoV-2 pneumonia. Multimodal imaging was
obtained. Full serological screening for infection was done resulting
negative. A diagnostic vitrectomy was impossible due to the limited access
at the surgery room. Diagnosis of presumed candida endophthalmitis was made,
according to a highly qualified center, and therapy with intravenous
liposomal amphotericin B was administered. At three months, we observed lack
of vitreous opacities and atrophic scars with no active lesions. Conclusions Diagnosis of candida endophthalmitis was a challenge in this pandemic
scenario, given the impossibility of performing a diagnostic vitrectomy.
Therefore, it was mainly based on patient's clinical manifestations,
multimodal imaging and on unanimity of collegiality between our hospital and
the highly specialized center.

Abstract
The landscape of fungal endocarditis (FE) has constantly been evolving in the last few decades. Despite the advancement in diagnostic methods and the introduction of newer antifungals, mortality remains high in FE. This systematic review aimed to evaluate the epidemiology, clinical features, diagnostic and therapeutic interventions in patients with FE. We also aim to examine the aforementioned factors as a determinant of mortality in FE. A literature search was performed in PubMed, Google Scholar and Scopus, and all patients ≥18 years with proven fungal endocarditis were included. A total of 220 articles (250 patients) were included in the final analysis. Candida was the commonest aetiology (49.6%), followed by Aspergillus (30%) and Scedosporium species (3.2%). The proportion of prosthetic valve endocarditis (PVE) and intravenous drug users was 35.2% and 16%, respectively. The overall mortality rate was 40%. On multivariate analysis, Aspergillus endocarditis (HR 3.7, 95% CI 1.4-9.7; p = .009) and immunocompromised state (HR 2.8, 95% CI 1.24-6.3; p = .013) were independently associated with mortality. Patients treated with surgery along antifungals had better survival (HR 0.20, 95% CI 0.09-0.42; p < .001) compared to those treated with antifungals alone. Recurrence of FE was reported in 10.4% of patients. In conclusion, FE carries significant mortality, particularly in immunodeficient and Aspergillus endocarditis. We advocate the use of surgery combined with antifungals to improve clinical outcomes.

Abstract
ABSTRACT Gastrointestinal (GI) symptoms often affect children with autism spectrum disorders (ASD) and GI symptoms have been associated with an abnormal fecal microbiome. There is limited evidence of Candida species being more prevalent in children with ASD. We enrolled 20 children with ASD and GI symptoms (ASD + GI), 10 children with ASD but no GI symptoms (ASD - GI), and 20 from typically developing (TD) children in this pilot study. Fecal mycobiome taxa were analyzed by Internal Transcribed Spacer sequencing. GI symptoms (GI Severity Index [GSI]), behavioral symptoms (Social Responsiveness Scale -2 [SRS-2]), inflammation and fungal immunity (fecal calprotectin and serum dectin-1 [ELISA]) were evaluated. We observed no changes in the abundance of total fungal species (alpha diversity) between groups. Samples with identifiable Candida spp. were present in 4 of 19 (21%) ASD + GI, in 5 of 9 (56%) ASD - GI, and in 4 of 16 (25%) TD children (overall P = 0.18). The presence of Candida spp. did not correlate with behavioral or GI symptoms (P = 0.38, P = 0.5, respectively). Fecal calprotectin was normal in all but one child. Finally, there was no significance in serum dectin-1 levels, suggesting no increased fungal immunity in children with ASD. Our data suggest that fungi are present at normal levels in the stool of children with ASD and are not associated with gut inflammation.

Abstract
Fungal infections are increasingly causing more morbidity and mortality, especially for immunocompromised people. In recent years, there is growing evidence that new medicine-resistant fungal strains are posing added challenges in the clinic. Nystatin is a known antifungal from the polyene family. Due to Nystatin limited solubility and high toxicity, it is used mainly to treat oral and dermal fungal infections. In search for new Nystatin derivatives and formulations, we obtained amide derivatives and a deoxycholate formulation that were not described previously for this compound. Furthermore, we tested the potency of the derivatives and formulation by the USP(81) method and minimum inhibitory concentration of Candida albicans and Aspergillus niger. Additionally, the in vitro toxicity and stability were tested, and it was found that the ethanol amide derivative of Nystatin was fully water-soluble (up to 100 mg/mL) with the same potency of Nystatin but with 13.5 times lower toxicity. The ethanol amide derivative of Nystatin is a promising candidate for future drug development.

Abstract
Candida is a rare cause of infected aortic aneurysms. We report the case of a diabetic patient with end stage kidney disease who underwent repair of a leaking abdominal aortic aneurysm. He was on long-term antibiotic treatment for malignant otitis externa. Candida albicans was isolated from the culture of the excised aneurysm wall. An infected aortic aneurysm due to Candida has not been previously reported in a patient with malignant otitis externa. This case report aims to highlight that Candida should be suspected as a cause of infected aortic aneurysms in patients with debilitation and chronic immunosuppression. Management of such cases can be extremely challenging, especially in resource-poor settings, and we will be touching upon the advantages and disadvantages of various treatment options.

Abstract
Tunneled hemodialysis catheters are the lifeline to patients on maintenance hemodialysis with failed arteriovenous fistulas. However, thrombosis and infection are the main causes of reduced longevity of these accesses. According to IDSA guidelines, catheter-related infection with Pseudomonas and fungi are absolute indications for catheter removal. Considering the cost and difficulties in catheter replacement, for those in whom all accesses are exhausted, retaining the same catheter may be lifesaving. We would like to present two patients in whom, 70% ethanol instillation was used to eradicate infection with these organisms as confirmed by repeat cultures post procedure. Hemodialysis is being successfully continued through the same catheter.

Abstract
Background: We describe a case of candida spondylodiscitis secondary to coronavirus disease (COVID-19). Case report: A 47-year-old man diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) required prolonged admission to the intensive care unit (ICU). Four months later, he was diagnosed with thoracic candida spondylodiscitis. Medical management was insufficient, so he eventually underwent surgery. Discussions: Fungal infections seem to be more likely in patients with COVID-19, but it is unknown whether they are directly attributed to COVID-19 or other surrounding factors. Regardless of the answer, the diagnosis is complicated, and the mortality rate is high. Lessons: COVID-19 is posing a challenge to the society, and new and unexpected diseases that had once disappeared have risen again. It is our duty to suspect them and to treat them in the most effective way possible.

Abstract
Fungal keratitis is a serious clinical infection on the cornea caused by fungi and is one of the leading causes of blindness in Asian countries. The treatment options are currently limited to a few antifungal agents. With the increasing incidence of drug-resistant infections, many patients fail to respond to antibiotics. Riboflavin-mediated corneal crosslinking (similar to photodynamic therapy (PDT)) for corneal ectasia was approved in the US in the early 2000s. Current evidence suggests that PDT could have the potential to inhibit fungal biofilm formation and overcome drug resistance by using riboflavin and rose bengal as photosensitizers. However, only a few clinical trials have been initiated in anti-fungal keratitis PDT treatment. Moreover, the removal of the corneal epithelium and repeated application of riboflavin and rose bengal are required to improve drug penetration before and during PDT. Thus, an improvement in trans-corneal drug delivery is mandatory for a successful and efficient treatment. In this article, we review the studies published to date using PDT against fungal keratitis and aim to enhance the understanding and awareness of this research area. The potential of modifying photosensitizers using nanotechnology to improve the efficacy of PDT on fungal keratitis is also briefly reviewed.

Abstract
BACKGROUND Deep tissue Candida invasion represents a special entity among neonates with invasive candidiasis. We aimed to explore the risk factors and clinical outcomes for deep tissue Candida invasion among neonates with invasive candidiasis. METHODS A retrospective data review of neonates admitted to NICU of Madinah maternity and children hospital, KSA from January 2012 to December 2019 was done. Data were analysed between infants with or without deep tissue candidiasis among infants with invasive candidiasis. Invasive candidiasis was defined as positive blood or catheter collected urine culture for Candida. Deep tissue Candida invasion was defined as an infection of the central nervous system, eyes, heart, skeletal system, lungs, liver or kidneys. RESULT A total of 14 (11%) out of 130 neonates with invasive candidiasis had deep tissue Candida invasion. Persistent positive blood culture for Candida [OR 15.2, 95% CI (2.0-114), p = .01], prematurity [OR 7.6, 95% CI (1.04-56.4), p = .04] and prolonged antibiotic duration [OR 1.3, 95% CI (1.02-1.6), p = .03] are independent risk factors for deep tissue Candida invasion. Deep tissue Candida invasion was associated with significantly higher rates of cerebral palsy, hydrocephalus, heart failure and longer length of hospital stay compared to infants without deep tissue invasion. CONCLUSION Persistent Candida growth in blood cultures, prematurity and long-term antibiotic use are significant risk factors for deep tissue Candida invasion. Deep tissue Candida invasion is associated with prolonged hospital stay and higher neonatal morbidity.

Abstract
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex multi-system disease with no cure and no FDA-approved treatment. Approximately 25% of patients are house or bedbound, and some are so severe in function that they require tube-feeding and are unable to tolerate light, sound, and human touch. The overall goal of this case report was to (1) describe how past events (e.g., chronic sinusitis, amenorrhea, tick bites, congenital neutropenia, psychogenic polydipsia, food intolerances, and hypothyroidism) may have contributed to the development of severe ME/CFS in a single patient, and (2) the extensive medical interventions that the patient has pursued in an attempt to recover, which enabled her to return to graduate school after becoming bedridden with ME/CFS 4.5 years prior. This paper aims to increase awareness of the harsh reality of ME/CFS and the potential complications following initiation of any level of intervention, some of which may be necessary for long-term healing. Treatments may induce severe paradoxical reactions (Jarisch–Herxheimer reaction) if high infectious loads are present. It is our hope that sharing this case will improve research and treatment options for ME/CFS.

Abstract
Background The increasing incidence of candidemia and emergence of drug-resistant Candida species are major concerns worldwide. Long-term surveillance studies are needed. Methods The Fungal Infection Network of Switzerland (FUNGINOS) conducted a 15-year (2004–2018), nationwide, epidemiological study of candidemia. Hospital-based incidence of candidemia, Candida species distribution, antifungal susceptibility, and consumption were stratified in 3 periods (2004–2008, 2009–2013, 2014–2018). Population-based incidence over the period 2009–2018 derived from the Swiss Antibiotic Resistance Surveillance System (ANRESIS). Results A total of 2273 Candida blood isolates were studied. Population and hospital-based annual incidence of candidemia increased from 2.96 to 4.20/100 000 inhabitants (P = .022) and 0.86 to 0.99/10 000 patient-days (P = .124), respectively. The proportion of Candida albicans decreased significantly from 60% to 53% (P = .0023), whereas Candida glabrata increased from 18% to 27% (P < .0001). Other non-albicans Candida species remained stable. Candida glabrata bloodstream infections occurred predominantly in the age group 18–40 and above 65 years. A higher proportional increase of C glabrata was recorded in wards (18% to 29%, P < .0001) versus intensive care units (19% to 24%, P = .22). According to Clinical and Laboratory Standards Institute, nonsusceptibility to fluconazole in C albicans was observed in 1% of isolates, and anidulafungin and micafungin nonsusceptibility was observed in 2% of C albicans and C glabrata. Fluconazole consumption, the most frequently used antifungal, remained stable, whereas use of mold-active triazoles and echinocandins increased significantly in the last decade (P < .0001). Conclusions Over the 15-year period, the incidence of candidemia increased. A species shift toward C glabrata was recently observed, concurring with increased consumption of mold-active triazoles.
