Abstract
OBJECTIVES To evaluate surgical outcomes of invasive fungal rhinosinusitis MATERIALS AND METHODS: The National Inpatient Sample Database (2000-2015 Q3) was queried for patients with a diagnosis of aspergillosis and/or mucormycosis and a diagnosis of acute sinusitis using the International Classification of Diseases, Ninth Edition. Factors associated with inpatient mortality were then identified with multivariate logistic regression. RESULTS 514 adult patients with a median age of 57.0 years were identified, of which 231 (44.9 %) underwent sinus surgery. Surgical patients had a longer length of stay (17.0 vs 9.0 days, p < 0.001) and higher total charges ($139,762.00 vs $57,945.00, p < 0.001). The number of sinus procedures was associated with reduced odds of inpatient mortality (OR 0.69; p < 0.001) in multivariate analysis. Hypertension (OR 0.34, p = 0.002) and chronic kidney disease (OR 0.23, p = 0.034) were associated with reduced odds of inpatient mortality. Total number of procedures (OR 1.24; p = 0.002), mucormycosis (OR 2.75, p = 0.002), age (OR 1.03, p = 0.006) and acid-base disorders (OR 2.85, p = 0.012) were associated with increased odds of inpatient mortality. CONCLUSION This represents the first large scale study to evaluate outcomes for invasive fungal rhinosinusitis. These findings suggest the odds of inpatient mortality decrease with greater extent of sinus surgery performed. The potentially protective roles of hypertension and chronic kidney disease should be evaluated in future research.

Abstract
Mucormycosis is the third most frequent invasive mycosis, following candidiasis and aspergillosis. It is frequently neglected due to its rare occurrence; but recently attend the status of notifiable disease due to its higher incidence in both developed and developing nations. India has received global notice since its estimated instances were greater than the global estimated figures. Mucormycosis has several clinical manifestations, including rhino-orbital-cerebral (ROCM), pulmonary, gastrointestinal, cutaneous, renal, and diffuse Mucormycosis. ROCM is the most frequent clinical manifestation in India, although pulmonary mucormycosis is prevalent worldwide. This review also discusses host defenses, pre disposing risk factors and fungal virulence factors that impair host's ability to prevent fungus invasion and disease establishment. The diagnosis of the disease depends on clinical interventions, histological or microbiological procedures along with molecular methods to obtain timely results. But there are still unmet challenges for rapid diagnosis of the disease. Treatment of the disease is achieved by multimodal approaches such as reversal of underlying predisposing factors, rapid administration of antifungals in optimal doses and surgical procedures to remove infected tissues. Liposomal Amphotericin B, Posaconazole and Isavuconazoles are preferred as the first line of treatment procedures. clinical trials. Different studies have improved the existing drug and under clinical trials while several studies predicted the new potential targets as CotH and Ftr1 as shown in infection and in vitro models. Therefore, current scenario demands a multidisciplinary approach is needed to investigate the prevalence, pathogenesis which is highly important for the advancement of rapid diagnosis and effective treatment.

Abstract
Although mucormycosis may have reached an epidemic situation during the COVID-19 pandemic, the term was much more familiar even before the COVID-19 period. The year 2020 showed an outbreak of novel coronavirus (SARS-CoV-2) which affected millions of people all over the world. One of the noticeable complications observed to be associated with this disease is mucormycosis. It is an opportunistic infection caused by members of the Order Mucorales existing worldwide and has been commonly reported as a laboratory contaminant for a long time. However, nowadays due to the changes in the host environment, they have been emerging as potent opportunistic pathogens responsible for causing primary infections or coinfections with other diseases eventually resulting in morbidity and even mortality in severe cases. Although immunocompromised patients are more susceptible to this infection, few cases have been reported in immunocompetent individuals. Various risk factors which are responsible for the acquisition of mucormycosis include diabetes mellitus type 2, ketoacidosis, hematological malignancies, organ transplants, and chemotherapy recipients. Among the various etiological agents, Rhizopus is found to be the most common, and rhino-cerebral to be the most frequent clinical presentation. As far as pathogenesis is concerned, host cell invasion, thrombosis, and necrosis are the main events in the progression of this disease. The aim of the present review is to address a complete spectrum of mucormycosis and COVID-19-associated mucormycosis (CAM) in a single article. Both global and Indian scenarios of mucormycosis are taken into account while framing this review.

Abstract
Combatting the ever-increasing threat from invasive fungal pathogens faces numerous fundamental challenges, including constant human exposure to large reservoirs of species in the environment, the increasing population of immunocompromised or immunosuppressed individuals, the unsatisfactory efficacy of current antifungal drugs and their associated toxicity, and the scientific and economic barriers limiting a new antifungal pipeline. DectiSomes represent a new drug delivery platform that enhances antifungal efficacy for diverse fungal pathogens and reduces host toxicity for current and future antifungals. DectiSomes employ pathogen receptor proteins - C-type lectins - to target drug-loaded liposomes to conserved fungal cognate ligands and away from host cells. DectiSomes represent one leap forward for urgently needed effective pan-antifungal therapy. Herein, we discuss the problems of battling fungal diseases and the state of DectiSome development.

Abstract
Introduction Mucormycosis is a rare systemic fungal infection, mainly observed in immunocompromised patients. It is responsible for surface and deep tissue destruction leading to perforations and hemorrhage. Its pathogenesis represented by an angio-invasion is at the origin of a local infarction and a vascular thrombosis. We report a case of gastrointestinal (GI) mucormycosis-induced multiple gastric ulcers, GI bleeding and rectal perforation. Case Presentation A 75-year-old man, with type II diabetes mellitus, was admitted to the intensive care unit for an acute abdominal pain associated with massive hematochezia. Clinical examination was that of an acute peritonitis and a hemorrhagic shock state. Abdominal and pelvic CT scan with intravenous contrast concluded to a perforation of the anterior wall of the rectum. He underwent immediate laparotomy with temporary colostomy. Several upper GI endoscopies had shown multiple gastric ulcer lesions. Lower GI endoscopy showed a fistulous orifice of the rectum on its anterior surface. Histopathology of the gastric biopsy showed acute and subacute inflammatory changes with filamentous elements suggesting mucormycosis. Histopathology of the rectal biopsy showed a subacute non-specific inflammation. Culture of the secretions from the rectal fistula orifice showed the strain Rhizopus sp. Antifungal susceptibility testing reported sensitivity to liposomal amphotericin B. The diagnosis of GI mucormycosis-induced multiple gastric ulcers, rectal perforation and pulmonary embolism in the patient with type II diabetes mellitus was retained. The outcomes were favorable after 6 weeks of treatment with liposomal amphotericin B associated with temporary colostomy and appropriate diabetes management. Conclusion GI mucormycosis remains a multidisciplinary diagnostic challenge, less frequent in clinical practice, with a long diagnostic pathway. This opportunistic systemic mycosis can lead to numerous GI complications including perforation, massive GI bleeding and even multiple extra-GI complications. GI mucormycosis has a good prognosis if it is treated early with medical and surgical treatment.

Abstract
Mucormycosis is a deadly opportunistic disease caused by a group of fungus named mucormycetes. Fungal spores are normally present in the environment and the immune system of the body prevents them from causing disease in a healthy immunocompetent individual. But when the defense mechanism of the body is compromised such as in the patients of diabetes mellites, neustropenia, organ transplantation recipients, and other immune-compromised states, these fungal spores invade our defense mechanism easily causing a severe systemic infection with approximately 45-80% of case fatality. In the present scenario, during the COVID-19 pandemic, patients are on immunosuppressive drugs, glucocorticoids, thus are at high risk of mucormycosis. Patients with diabetes mellitus are further getting a high chance of infection. Usually, the spores gain entry through our respiratory tract affecting the lungs and paranasal sinuses. Besides, they can also enter through damage into the skin or through the gastrointestinal route. This review article presents the current statistics, the causes of this infection in the human body, and its diagnosis with available recent therapies through recent databases collected from several clinics and agencies. The diagnosis and identification of the infection were made possible through various latest medical techniques such as computed tomography scans, direct microscopic observations, MALDI-TOF mass spectrometry, serology, molecular assay, and histopathology. Mucormycosis is so uncommon, no randomized controlled treatment studies have been conducted. The newer triazoles, posaconazole (POSA) and isavuconazole (ISAV) (the active component of the prodrug isavuconazonium sulfate) may be beneficial in patients who are refractory to or intolerant of Liposomal Amphotericin B. but due to lack of early diagnosis and aggressive surgical debridement or excision, the mortality rate remains high. In the course of COVID-19 treatments, there must be more vigilance and alertness are required from clinicians to evaluate these invasive fungal infections.

Abstract
There are limited data on the clinical outcomes of percutaneous coronary intervention (PCI) in patients with acquired immunosuppression who are frequently underrepresented in clinical trials. All PCI procedures between October 2015 and December 2018 in the Nationwide Inpatient Sample were retrospectively analyzed, stratified by immunosuppression status. Multivariable logistic regression models were performed to examine (1) the association between immunosuppression status and in-hospital outcomes, expressed as adjusted odds ratio (aOR) with 95% confidence intervals (CIs) and (2) predictors of mortality among patients with severe acquired immunosuppression. In this contemporary analysis of nearly 1.5 million PCI procedures, approximately 4% of patients who underwent PCI had acquired immunosuppression. Of these, chronic steroid use accounted for approximately half of the cohort who underwent PCI who had acquired immunosuppression, with the remainder divided between hematologic cancer, solid organ active malignancy, and metastatic cancer, with the latter group having the highest rates of composite of in-hospital mortality or stroke (9.3%) (mortality 7.5% and acute ischemic stroke 2.4%). In conclusion, immunosuppression was independently associated with increased adjusted odds of adverse clinical outcomes, specifically mortality or stroke (aOR 1.11, 95% CI 1.06 to 1.15, p <0.001) and in-hospital mortality (aOR 1.21, 95% CI 1.13 to 1.29, p <0.001), with outcomes dependent on the cause of immunosuppression.

Abstract
INTRODUCTION During Operation Enduring Freedom in Afghanistan, an outbreak of combat-related invasive fungal wound infections (IFIs) emerged among casualties with dismounted blast trauma and became a priority issue for the Military Health System. METHODS In 2011, the Trauma Infectious Disease Outcomes Study (TIDOS) team led the Department of Defense IFI outbreak investigation to describe characteristics of IFIs among combat casualties and provide recommendations related to management of the disease. To support the outbreak investigation, existing IFI definitions and classifications utilized for immunocompromised patients were modified for use in epidemiologic research in a trauma population. Following the conclusion of the outbreak investigation, multiple retrospective analyses using a population of 77 IFI patients (injured during June 2009 to August 2011) were conducted to evaluate IFI epidemiology, wound microbiology, and diagnostics to support refinement of Joint Trauma System (JTS) clinical practice guidelines. Following cessation of combat operations in Afghanistan, the TIDOS database was comprehensively reviewed to identify patients with laboratory evidence of a fungal infection and refine the IFI classification scheme to incorporate timing of laboratory fungal evidence and include categories that denote a high or low level of suspicion for IFI. The refined IFI classification scheme was utilized in a large-scale epidemiologic assessment of casualties injured over a 5.5-year period. RESULTS Among 720 combat casualties admitted to participating hospitals (2009-2014) who had histopathology and/or wound cultures collected, 94 (13%) met criteria for an IFI and 61 (8%) were classified as high suspicion of IFI. Risk factors for development of combat-related IFIs include sustaining a dismounted blast injury, experiencing a traumatic transfemoral amputation, and requiring resuscitation with large-volume (>20 units) blood transfusions. Moreover, TIDOS analyses demonstrated the adverse impact of IFIs on wound healing, particularly with order Mucorales. A polymerase chain reaction (PCR)-based assay to identify filamentous fungi and support earlier IFI diagnosis was also assessed using archived formalin-fixed, paraffin-embedded tissue specimens. Although the PCR-based assay had high specificity (99%), there was low sensitivity (63%); however, sensitivity improved to 83% in tissues collected from sites with angioinvasion. Data obtained from the initial IFI outbreak investigation (37 IFI patients) and subsequent TIDOS analyses (77 IFI patients) supported development and refinement of a JTS clinical practice guideline for the management of IFIs in war wounds. Furthermore, a local clinical practice guideline to screen for early tissue-based evidence of IFIs among blast casualties at the Landstuhl Regional Medical Center was critically evaluated through a TIDOS investigation, providing additional clinical practice support. Through a collaboration with the Uniformed Services University Surgical Critical Care Initiative, findings from TIDOS analyses were used to support development of a clinical decision support tool to facilitate early risk stratification. CONCLUSIONS Combat-related IFIs are a highly morbid complication following severe blast trauma and remain a threat for future modern warfare. Our findings have supported JTS clinical recommendations, refined IFI classification, and confirmed the utility of PCR-based assays as a complement to histopathology and/or culture to promote early diagnosis. Analyses underway or planned will add to the knowledge base of IFI epidemiology, diagnostics, prevention, and management.

Abstract
Biological sex, which comprises differences in host sex hormone homeostasis and immune responses, can have a substantial impact on the epidemiology of infectious diseases. Comprehensive data on sex distributions in invasive fungal diseases (IFDs) is lacking. In this review we performed a literature search of in vitro/animal studies, clinical studies, systematic reviews, and meta-analyses of invasive fungal infections. Females represented 51.2% of invasive candidiasis cases, mostly matching the proportions of females among the general population in the United States and Europe (>51%). In contrast, other IFDs were overrepresented in males, including invasive aspergillosis (51% males), mucormycosis (60%), cryptococcosis (74%), coccidioidomycosis (70%), histoplasmosis (61%), and blastomycosis (66%). Behavioral variations, as well as differences related to biological sex, may only in part explain these findings. Further investigations concerning the association between biological sex/gender and the pathogenesis of IFDs is warranted.

Abstract
BACKGROUND Invasive mucormycosis (IM) is a rare and often life-threatening fungal infection, for which clinical and epidemiological understanding is lacking. Electronic health record (EHR) data can be utilized to elucidate large populations of patients with IM to address this unmet need. This study aimed to descriptively assess data on patients with IM using the Optum® EHR dataset. METHODS US patient data from the Optum® deidentified EHR dataset (2007-2019) were analyzed to identify patients with IM. Patients with hematologic malignancies (HM), at high risk of IM, were selected and sorted by IM diagnosis (ICD9 117.7; ICD10 B46). Demographics, comorbidities/other diagnoses, and treatments were analyzed in patients with IM. RESULTS In total, 1133 patients with HM and IM were identified. Most were between 40 and 64 years of age, Caucasian, and from the Midwest. Essential primary hypertension (50.31%) was the most common comorbidity. Of the 1133 patients, only 33.72% were prescribed an antifungal treatment. The most common antifungal treatments were fluconazole (24.27%) and posaconazole (16.33%), which may have been prophylactic, and any AmB (15.62%). CONCLUSIONS A large population of patients with IM were identified, highlighting the potential of analyzing EHR data to investigate epidemiology, diagnosis, and the treatment of apparently rare diseases.

Abstract
The aim of the work is to attract the attention of specialists: dentists, oncologists, hematologists to thorough sanitation of the oral cavity of patients preparing for chemotherapy treatment, to transplantation of hematopoietic stem cells. Two clinical cases described in the article were observed at the R.M. Gorbacheva First Saint-Petersburg State Medical University from 2010 to 2019. They confirm the possibility of the occurrence of infectious complications with damage to the maxillofacial region caused by rare pathogens of invasive mycosis, which debuted as an odontogenic inflammatory process. The success of the treatment of Invasive Mycosis depends on early diagnosis and antimycotic therapy; active surgical tactics in relation to the affected tissues in a controlled course of the underlying disease and the restoration of effective hematopoiesis.

Abstract
Background Gastrointestinal mucormycosis (GIM) is a rare, opportunistic fungal infection with poor prognosis. Clinically, it is difficult to diagnose GIM owing to its nonspecific clinical symptoms and poor suspicion. The estimated incidence of GIM is inaccurate, and most cases are diagnosed accidentally during surgery or upon postmortem examination. GIM usually occurs in patients with immune deficiencies or diabetes. Here, we report two cases of immunocompetent young patients with GIM who had good prognosis after treatment. Compared to other case reports on GIM, our cases had unusual infection sites and no obvious predisposing factors, which make it important to highlight these cases. Case presentation The first case was that of a 16-year-old immunocompetent boy who was admitted with gastrointestinal bleeding and perforation due to a gastric ulcer. Strategies used to arrest bleeding during emergency gastroscopy were unsuccessful. An adhesive mass was then discovered through laparoscopy. The patient underwent type II gastric resection. Pathological examination of the mass revealed bacterial infection and GIM. The second case was of a 33-year-old immunocompetent woman with a recent history of a lower leg sprain. The patient subsequently became critically ill and required ventilatory support. After hemodynamic stabilization and extubation, she presented with hematemesis due to exfoliation and necrosis of the stomach wall. The patient underwent total gastrectomy plus jejunostomy. The pathology results revealed severe bacterial infection and fungal infection that was confirmed as GIM. The patient fully recovered after receiving anti-infective and antifungal treatments. Conclusions Neither patient was immunosuppressed, and both patients presented with gastrointestinal bleeding. GIM was confirmed via pathological examination. GIM is not limited to immunocompromised patients, and its diagnosis mainly relies on pathological examination. Early diagnosis, timely surgical treatment, and early administration of systemic drug treatment are fundamental to improving its prognosis.

Abstract
Pulmonary mucormycosis and aspergillosis with disseminated mucormycosis involving gastrointestinalin is a very rare but lethal infection leading to extreme mortality. Herein, we present a unique case of pulmonary coinfection with Cunninghamella bertholletiae and Aspergillus flavus, with disseminated mucormycosis involving the jejunum caused by C. bertholletiae in an acute B-lymphocytic leukemia (B-ALL) patient with familial diabetes. Early administration of active antifungal agents at optimal doses and complete resection of all infected tissues led to improved therapeutic outcomes.

Abstract
Mucormycosis is an opportunistic fungal infection caused by molds within the order Mucorales. The rhino-orbital-cerebral localization is the most frequent. It is a destructive, necrotizing and potentially fatal disease. The treatment involves aggressive surgical debridement combined with antifungal drugs. The course is quickly fatal in the event of delayed diagnosis and / or treatment. This infection usually affects immunocompromised and diabetic patients, but cases of mucormycosis in immunocompetents are increasingly reported. Chronic mucormycosis is extremely rare and affects both immunocompromised and immunocompetent patients, its clinical evolution is nonspecific and its treatment is not standardized. We report the case of a destructive rhino-orbital and pulmonary involvement in a 59 years old immunocompetent patient who presented a right periorbital edema associated and a vision loss and a notion of nasal obstruction and progressive onset headache four months before admission. Her condition progressed with rapidly extensive necrosis. She underwent extensive surgical resection but soon succumbed to multiple organ failure. The diagnosis of mucormycosis was confirmed post mortem on the excisional piece. The purpose of this article is to draw attention to chronic mucormycosis in the immunocompetent and to emphasize the importance of early diagnosis and adequate management of this fatal infection.

Abstract
BACKGROUND Invasive fungal infection is a major source of morbidity and mortality. The usage of microbial cell-free DNA for the detection and identification of invasive fungal infection has been considered as a potential alternative to invasive procedures allowing for rapid results. OBJECTIVE This analysis aimed to assess the budget implications of using the Karius® Test in patients suspected of invasive fungal infection in an average state in the USA from a healthcare payer perspective. METHODS The analysis used a decision tree to capture key stages of the patient pathway, from suspected invasive fungal infection to either receiving treatment for invasive fungal infection or being confirmed as having no invasive fungal infection. The analysis used published costs and resource use from a targeted review of the literature. Because of the paucity of published evidence on the reduction of diagnostic tests displaced by the Karius Test, the analysis used a 50% reduction in the use of bronchoscopy and/or bronchoalveolar lavage. The impact of this reduction was tested in a scenario analysis. RESULTS The results of the analysis show that the introduction of the Karius Test is associated with a cost saving of US$2277 per patient; when multiplied by the estimated number of cases per year, the cost saving is US$17,039,666. The scenario analysis showed that the Karius Test only had an incremental cost of US$87 per patient when there was no reduction in bronchoscopy and bronchoalveolar lavage. CONCLUSIONS The Karius Test may offer a valuable and timely option for the diagnosis of invasive fungal infection through its non-invasive approach and subsequent cost savings.

Abstract
Rhizopus infection is an often-fatal complication after transplant. We present a 3-year-old pediatric patient with end-stage renal disease due to congenital hypoplastic kidneys who underwent deceased donor renal transplant. Approximately 3 months after transplant, the patient underwent renal biopsy for a presentation of fevers, acute kidney injury, and imaging evidence of hydronephrosis. The patient was found to have a Rhizopus infection of the transplanted kidney and underwent transplant nephrectomy. In addition to surgical debridement of the infection, the patient was treated with long-term antifungal therapy for complete eradication. After intervention, the patient has had no clinical or imaging evidence of residual or recurrent disease and has been reactivated on the transplant wait list. The positive outcome in this case highlights the importance of rapid diagnosis and treatment of a lethal complication.

Abstract
OBJECTIVE To evaluate outcomes, healthcare resource utilization, and costs associated with mucormycosis in inpatient settings in Japan. METHODS We performed a systematic literature review, followed by a retrospective database study using hospital health claims for patients in Japan hospitalized with a diagnosis of mucormycosis between January 2010 and January 2019. Outcomes assessed included duration of index hospitalization; index stay mortality; hospital readmission within 30, 60, and 90 days after index hospitalization discharge; drug/treatment utilization and patterns; number of patients examined for mucormycosis during the index hospitalization; and index stay inpatient costs. RESULTS From our systematic literature review of articles describing 133 patients with mucormycosis, mortality in the index hospitalization was 55.6%. From our database study of 126 patients hospitalized for mucormycosis, mortality during the index hospitalization was 35.7% and mean index stay duration was 94 days. Hematologic malignancies were the most common risk factor in the literature review and the most common comorbidity in the database study. During the index stay, 39 patients (31.0%) received liposomal amphotericin B (L-AMB) treatment and 74 patients (58.7%) received other antifungal treatments. Median total inpatient costs for the index hospitalization were equivalent to approximately US$60,945, including US$29,283 in drug costs. CONCLUSIONS This study investigated the healthcare resource utilization and cost of medical resources caused by mucormycosis in Japan. The drug costs for antifungal treatments comprised about half of total inpatient costs. Mucormycosis leads to high mortality, high healthcare resource utilization, and high costs.

Abstract
BACKGROUND Fungal diseases range from relatively-minor superficial and mucosal infections to severe, life-threatening systemic infections. Delayed diagnosis and treatment can lead to poor patient outcomes and high medical costs. The overall burden of fungal diseases in the United States is challenging to quantify, because they are likely substantially underdiagnosed. METHODS To estimate the total, national, direct medical costs associated with fungal diseases from a healthcare payer perspective, we used insurance claims data from the Truven Health MarketScan 2014 Research Databases, combined with hospital discharge data from the 2014 Healthcare Cost and Utilization Project National Inpatient Sample and outpatient visit data from the 2005-2014 National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey. All costs were adjusted to 2017 dollars. RESULTS We estimate that fungal diseases cost more than $7.2 billion in 2017, including $4.5 billion from 75055 hospitalizations and $2.6 billion from 8993230 outpatient visits. Hospitalizations for Candida infections (n = 26735, total cost $1.4 billion) and Aspergillus infections (n = 14820, total cost $1.2 billion) accounted for the highest total hospitalization costs of any disease. Over half of outpatient visits were for dermatophyte infections (4981444 visits, total cost $802 million), and 3639037 visits occurred for non-invasive candidiasis (total cost $1.6 billion). CONCLUSIONS Fungal diseases impose a considerable economic burden on the healthcare system. Our results likely underestimate their true costs, because they are underdiagnosed. More comprehensive estimates of the public health impact of these diseases are needed to improve their recognition, prevention, diagnosis, and treatment.

Abstract
BACKGROUND Invasive fungal infection (IFI) in solid organ transplant (SOT) recipients is associated with significant morbidity and mortality. The long-term probability of post-transplant IFI is poorly understood. METHODS We conducted a population-based cohort study using linked administrative healthcare databases from Ontario, Canada, to determine the incidence rate; 1-, 5-, and 10-year cumulative probabilities of IFI; and post-IFI all-cause mortality in SOT recipients from 2002 to 2016. We also determined post-IFI, death-censored renal allograft failure. RESULTS We included 9326 SOT recipients (median follow-up: 5.35 years). Overall, the incidence of IFI was 8.3 per 1000 person-years. The 1-year cumulative probability of IFI was 7.4% for lung, 5.4% for heart, 1.8% for liver, 1.2% for kidney-pancreas, and 1.1% for kidney-only allograft recipients. Lung transplant recipients had the highest incidence rate and 10-year probability of IFI: 43.0 per 1000 person-years and 26.4%, respectively. The 1-year all-cause mortality rate after IFI was 34.3%. IFI significantly increased the risk of mortality in SOT recipients over the entire follow-up period (hazard ratio: 6.50, 95% CI: 5.69-7.42). The 1-year probability of death-censored renal allograft failure after IFI was 9.8%. CONCLUSION Long-term cumulative probability of IFI varies widely among SOT recipients. Lung transplantation was associated with the highest incidence of IFI with considerable 1-year all-cause mortality.

Abstract
INTRODUCTION Prophylaxis and treatment of invasive aspergillosis (IA) and mucormycosis (IM) within a real-world US inpatient setting is undocumented since the introduction of isavuconazole. This retrospective medical record review aimed to describe characteristics, triazole use, and outcomes among inpatients across the USA who initiated antifungal monotherapy (AFMT) as prophylaxis or treatment of IA/IM. METHODS A convenience sample of US physicians abstracted data from randomly selected records of hospitalized patients aged ≥ 18 years initiating AFMT (amphotericin B, isavuconazole, voriconazole, or posaconazole) as prophylaxis or treatment of IA/IM between 2013 and 2017. Retrieved data included background characteristics, dosage and duration of AFMT, healthcare resource use, and survival. Characteristics and outcomes were compared (prophylaxis vs treatment) using Fisher's exact and one-way analysis of variance tests where applicable. Exploratory Kaplan-Meier analyses described overall and inpatient survival. RESULTS Physicians (n = 23) retrieved 124 patient records (43 prophylaxis; 81 treatment). Median duration of first-line AFMT was 14 days (range 1-603 days) and 19 days (range 3-351 days) in the prophylaxis and treatment groups, respectively. One patient received second-line therapy. Median duration of hospitalization was 29 days (range 4-259 days) and 31 days (range 6-980 days) in the prophylaxis and treatment groups, respectively. Admission to intensive care occurred in 14% and 52% of patients in the prophylaxis and treatment groups, respectively. At the time of data retrieval, overall and inpatient survival rates in the prophylaxis group were 88% and 87%, respectively, and in the treatment group were 66% and 76%, respectively. CONCLUSIONS This study documented real-world prophylactic and therapeutic AFMT use for IA/IM and associated outcomes among hospitalized patients in the USA since approval of isavuconazole. IA/IM were associated with lengthy hospital stays commonly requiring intensive care. Prophylactic and therapeutic AFMT dosages and duration generally followed recommendations and switching between agents was rare. FUNDING Astellas Pharma Global Development, Inc., Northbrook, IL, USA.

Abstract
Background Though invasive aspergillosis (IA) complicates care of up to 13% of patients with immunocompromise, little is known about its morbidity and mortality burden in the United States. Methods We analyzed the Health Care Utilization Project's data from the Agency for Healthcare Research and Quality for 2009-2013. Among subjects with high-risk conditions for IA, IA was identified via International Classification of Diseases, Ninth Revision, Clinical Modification codes 117.3, 117.9, and 484.6. We compared characteristics and outcomes between those with (IA) and without IA (non-IA). Using propensity score matching, we calculated the IA-associated excess mortality and 30-day readmission rates, length of stay, and costs. Results Of the 66634683 discharged patients meeting study inclusion criteria, 154888 (0.2%) had a diagnosis of IA. The most common high-risk conditions were major surgery (50.1%) in the non-IA and critical illness (41.0%) in the IA group. After propensity score matching, both mortality (odds ratio, 1.43; 95% confidence interval, 1.36-1.51) and 30-day readmission (1.39; 1.34-1.45) rates were higher in the IA group. IA was associated with 6.0 (95% confidence interval, 5.7-6.4) excess days in the hospital and $15542 ($13869-$17215) in excess costs per hospitalization. Conclusions Although rare even among high-risk groups, IA is associated with increased hospital mortality and 30-day readmission rates, excess duration of hospitalization, and costs. Given nearly 40000 annual admissions for IA in the United States, the aggregate IA-attributable excess costs may reach $600 million annually.

Abstract
Emerging evidence has shown that vitamin D deficiency may be related with community-acquired pneumonia (CAP), but individually published studies showed inconclusive results. The aim of this study was to quantitatively summarize the association between vitamin D and the CAP.We conducted this meta-analysis though a systematic literature search of PubMed, Medline, and EMBASE up to 31 September 2018 with the following keywords 'vitamin D' or 'cholecalciferol' or '25-hydroxyvitamin D' or '25(OH)D' in combination with 'community-acquired pneumonia' or 'CAP' or 'pneumonia' with no limitations. This meta-analysis was performed following the guidelines of Meta-analysis of Observational Studies in Epidemiology. The association between vitamin D levels and CAP were measured as odds ratio (OR) and weighted mean difference (WMD). Results were combined using a random-effect or a fix-effect meta-analysis, and sensitivity analyses were conducted to explore potential factors.Eight observational studies involving 20,966 subjects were included. In this meta-analysis, CAP patients with vitamin D deficiency (serum 25(OH)D levels <20 ng/mL) experienced a significantly increased risk of CAP (odds ratio (OR) = 1.64, 95% confidence intervals (CI): 1.00, 2.67), and an obvious decrease of -5.63 ng/mL (95% CI: -9.11, -2.14) in serum vitamin D was demonstrated in CAP patients. Sensitivity analysis showed that exclusion of any single study did not materially alter the overall combined effect.The evidence from this meta-analysis indicates an association between vitamin D deficiency and an increased risk of CAP patients. However, well-designed trails are required to determine the explicit effect of vitamin D supplementation.

Abstract
A retrospective data analysis using 2004-2014 Healthcare Cost and Utilization Project Nationwide Inpatient Sample was conducted to examine in-hospital mortality among adults with autism spectrum disorders in the United States compared to individuals in the general population. We modeled logistic regressions to compare inpatient hospital mortality between adults with autism spectrum disorders (n = 34,237) and age-matched and sex-matched controls (n = 102,711) in a 1:3 ratio. Adults with autism spectrum disorders had higher odds for inpatient hospital mortality than controls (odds ratio = 1.44, 95% confidence interval: 1.29-1.61, p < 0.001). This risk remained high even after adjustment for age, sex, race/ethnicity, income, number of comorbidities, epilepsy and psychiatric comorbidities, hospital bed size, hospital region, and hospitalization year (odds ratio = 1.51, 95% confidence interval: 1.33-1.72, p < 0.001). Adults with autism spectrum disorders who experienced in-hospital mortality had a higher risk for having 10 out of 27 observed Elixhauser-based medical comorbidities at the time of death, including psychoses, other neurological disorders, diabetes, hypothyroidism, rheumatoid arthritis collagen vascular disease, obesity, weight loss, fluid and electrolyte disorders, deficiency anemias, and paralysis. The results from the interaction of sex and autism spectrum disorders status suggest that women with autism spectrum disorders have almost two times higher odds for in-hospital mortality (odds ratio = 1.95, p < 0.001) than men with autism spectrum disorders. The results from the stratified analysis also showed that women with autism spectrum disorders had 3.17 times higher odds (95% confidence interval: 2.50-4.01, p < 0.001) of in-hospital mortality compared to women from the non-autism spectrum disorders matched control group; this difference persisted even after adjusting for socioeconomic, clinical, and hospital characteristics (odds ratio = 2.75, 95% confidence interval: 2.09-3.64, p < 0.001). Our findings underscore the need for more research to develop better strategies for healthcare and service delivery to people with autism spectrum disorders.

Abstract
The diagnosis and treatment of mucormycosis are challenging. The incidence of the disease seems to be increasing. Hematological malignancies are the most common underlying disease in countries with high income and uncontrolled diabetes in developing countries. Clinical approach to diagnosis lacks sensitivity and specificity. Radiologically, multiple (≥10) nodules and pleural effusion are reportedly associated with pulmonary mucormycosis. Another finding on computerized tomography (CT) scan, which seems to indicate the presence of mucormycosis, is the reverse halo sign. Microscopy (direct and on histopathology) and culture are the cornerstones of diagnosis. Molecular assays can be used either for detection or identification of mucormycetes, and they can be recommended as valuable add-on tools that complement conventional diagnostic procedures. Successful management of mucormycosis is based on a multimodal approach, including reversal or discontinuation of underlying predisposing factors, early administration of active antifungal agents at optimal doses, complete removal of all infected tissues, and use of various adjunctive therapies. Our armamentarium of antifungals is slightly enriched by the addition of two newer azoles (posaconazole and isavuconazole) to liposomal amphotericin B, which remains the drug of choice for the initial antifungal treatment, according to the recently published guidelines by ECIL-6, as well as those published by ECMM/ESCMID. Despite the efforts for better understanding of the pathogenesis, early diagnosis and aggressive treatment of mucormycosis, the mortality rate of the disease remains high.

Abstract
BACKGROUND Invasive mucormycosis (IM) is a rare invasive fungal infection with a high mortality rate. However, data concerning the clinical and economic burden of IM are scarce. AIM To evaluate the direct treatment costs and additional expenditures of patients with IM. METHODS A retrospective cost-of-illness analysis of cases with IM extracted from FungiScope - Global Registry for Emerging Fungal Infections, accessible through the epidemiological research platform www.ClinicalSurveys.net, was undertaken. Results of patients with IM were compared with those of matched patients with similar underlying conditions based on the German Diagnosis Related Group (G-DRG) coding. FINDINGS Out of 46 patients with probable/proven IM, 31 (67%) patients were male and the median age was 53 years (range 11-88 years). Forty-two patients (92%) had haematological diseases as the most common risk factor. Analysis of cost factors identified antifungal treatment due to IM as the primary cost driver [€22,816, 95% confidence interval (CI) €15,036-32,346], with mean overall direct treatment costs of €53,261 (95% CI €39,660-68,825). Compared with matched patients, patients with IM were treated in hospital for 26.5 additional days (standard deviation 31.8 days; P < 0.001), resulting in mean additional costs of €32,991 (95% CI €21,558-46,613; P < 0.001). Probable IM, as well as absence of chemotherapy, surgical measures due to IM, and antifungal prophylaxis were associated with lower overall costs. Nineteen patients (41.3%) died during hospitalization. CONCLUSION This study demonstrates the considerable healthcare burden of IM. The choice of antifungal agent for treatment of IM had no impact on overall cost.

In Vitro Activity of Isavuconazole against Opportunistic Fungal Pathogens from Two Mycology Reference Laboratories. Antimicrob Agents Chemother 2018; 62:AAC.01230-18. [PMID: 30061288 PMCID: PMC6153788 DOI: 10.1128/aac.01230-18] [Citation(s) in RCA: 40] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Accepted: 07/19/2018] [Indexed: 12/21/2022] Open
Abstract
Monitoring antifungal susceptibility patterns for new and established antifungal agents seems prudent given the increasing prevalence of uncommon species associated with higher antifungal resistance. We evaluated the activity of isavuconazole against 4,856 invasive yeasts and molds collected worldwide. The 4,856 clinical fungal isolates, including 2,351 Candida species isolates, 97 non-Candida yeasts, 1,972 Aspergillus species isolates, and 361 non-Aspergillus molds, including 292 Mucorales isolates collected in 2015 to 2016, were tested using CLSI methods. The MIC values for isavuconazole versus Aspergillus ranged from 0.06 to ≥16 μg/ml. The modal MIC for isavuconazole was 0.5 μg/ml (range, 0.25 [A. nidulans and A. terreus species complex] to 4 μg/ml [A. calidoustus and A. tubingensis]). Eight A. fumigatus isolates had elevated isavuconazole MIC values at ≥8 μg/ml (non-wild type). Isavuconazole showed comparable activity to itraconazole against the Mucorales The lowest modal isavuconazole MIC values were seen for Rhizopus spp., R. arrhizus var. arrhizus, and R. microsporus (all 1 μg/ml). Candida species isolates were inhibited by ≤0.25 μg/ml of isavuconazole (range, 96.1% [C. lusitaniae] to 100.0% [C. albicans, C. dubliniensis, C. kefyr, and C. orthopsilosis]). MIC values were ≤1 μg/ml for 95.5% of C. glabrata isolates and 100.0% of C. krusei isolates. Isavuconazole was active against the non-Candida yeasts, including Cryptococcus neoformans (100.0% at ≤0.5 μg/ml). Isavuconazole exhibited excellent activity against most species of Candida and Aspergillus Isavuconazole was comparable to posaconazole and voriconazole against the less common yeasts and molds. Isavuconazole was generally less active than posaconazole and more active than voriconazole against the 292 Mucorales isolates. We confirm the potentially useful activity of isavuconazole against species of Rhizopus as determined by CLSI methods.

Abstract
Despite the recent introduction of mold-active agents (posaconazole and isavuconazole), in addition to amphotericin B products, to our armamentarium against mucormycosis, many uncertainties remain for the management of this uncommon opportunistic infection, as there are no data from prospective randomized clinical trials to guide therapy. In this mini-review, we present the current status of treatment options. In view of the heterogeneity of the disease (different types of affected hosts, sites of infection, and infecting Mucorales), mucormycosis management requires an individualized management plan that takes into account the net state of immunosuppression of the host, including comorbidities, certainty of diagnosis, site of infection, and antifungal pharmacological properties.

Abstract
Aim: Invasive mold diseases (IMDs) are associated with significant morbidity and mortality. Approved treatments include voriconazole (VORI), liposomal amphotericin B (L-AMB), posaconazole (POSA) and isavuconazole (ISAV). A UK-based economic model was developed to explore the cost of treating IMDs with ISAV versus L-AMB followed by POSA. Materials & methods: As indirect comparisons have demonstrated similar efficacy between the comparators, a cost-minimization approach was taken. Drug acquisition, administration & monitoring, and hospitalization costs were evaluated from the healthcare system perspective. Results: Per-patient costs were UK£14,842 with ISAV versus UK£18,612 with L-AMB followed by POSA. Savings were driven by drug acquisition, and administration & monitoring costs. Conclusion: ISAV has the potential to reduce IMD treatment costs relative to L-AMB followed by POSA.

Abstract
AIM Mucormycosis is a fungal infection associated with high mortality. Until recently, the only licensed treatments were amphotericin B (AMB) formulations. Isavuconazole (ISAV) is a new mucormycosis treatment. A UK-based economic model explored treatment costs with ISAV versus liposomal AMB followed by posaconazole. MATERIALS & METHODS As a matched case-control analysis showed similar efficacy for ISAV and AMB, a cost-minimization approach was taken. Direct costs - drug acquisition, monitoring and administration, and hospitalization costs - were estimated from the National Health Service perspective. RESULTS Per-patient costs for ISAV and liposomal AMB + posaconazole were UK£26,810 and UK£41,855, respectively, with savings primarily driven by drug acquisition and hospitalization costs. CONCLUSION ISAV may reduce costs compared with standard mucormycosis therapy.

Abstract
BACKGROUND Invasive aspergillosis (IA) and mucormycosis contribute to substantial mortality, especially among immunocompromised persons, including those with hematopoietic stem cell transplant (HSCT), hematologic malignancy (HM), and solid organ transplant (SOT). METHODS Using International Classification of Diseases, Ninth Revision codes available in the National Inpatient Sample, a hospital discharge database, we estimated IA-related hospitalizations (IA-RH), mucormycosis-RH (M-RH), HSCT-RH, HM-RH, and SOT-RH during 2000-2013. United States census data were used to calculate overall M-RH and IA-RH rates and present trends; estimated annual numbers of HSCT-RH, HM-RH, and SOT-RH served as denominators to calculate M-RH and IA-RH rates occurring with these conditions. Weighted least-squares technique was used to test for linear trends and calculate average annual percentage change (APC). RESULTS There were an estimated 169 110 IA-RH and 9966 M-RH during 2000-2013. Overall, IA-RH and M-RH rates per million persons rose from 32.8 to 46.0 (APC = +2.9; P < .001) and 1.7 to 3.4 (APC = +5.2%; P < .001), respectively, from 2000 to 2013. Among HSCT-RH, there was no significant change in M-RH rate, but a significant decline occurred in IA-RH rate (APC = -4.6%; P = .004). Among HM-RH, the rate of M-RH increased (APC = +7.0%; P < .001), but the IA-RH rate did not change significantly (APC = +1.2%; P = .073). Among SOT-RH, M-RH (APC = +6.3%; P = .038) and IA-RH rates (APC = +4.1%; P < .001) both increased. CONCLUSIONS Overall IA-RH and M-RH rates increased during 2000-2013, with a doubling of M-RH. Mucormycosis-related hospitalization occurring in conjunction with certain comorbidities increased, whereas IA-RH rates among patients with the comorbidities, decreased, remained stable, or increased to a lesser extent than M-RH.

Abstract
Background Mucormycosis is a rare but devastating fungal infection primarily affecting immunocompromised patients such as those with hematological malignancy, bone marrow and solid organ transplantation, and patients with diabetes, and, even more rarely, immunocompetent patients. The objective of this study was to assess the prevalence and burden, both clinical and economic, of mucormycosis among hospitalized patients in the U.S. Methods This is a retrospective study using the Premier PerspectiveTM Comparative Database, with more than 560 participating hospitals covering 104 million patients (January 2005-June 2014). All hospitalizations in the database were evaluated for the presence of mucormycosis using either an ICD-9 code of 117.7 or a positive laboratory result for Mucorales. Hospitalizations were further required to have prescriptions of amphotericin B or posaconazole to be considered as mucormycosis-related hospitalizations. The prevalence of mucormycosis-related hospitalizations among all hospital discharges was estimated. Mortality rate at discharge, length of hospital stay, and readmission rates at 1 and 3 months were evaluated among mucormycosis-related hospitalizations. Cost per hospital stay and average per diem cost (inflated to 2014 USD) were reported. Results The prevalence of mucormycosis-related hospitalizations was estimated as 0.12 per 10,000 discharges during January 2005-June 2014. It increased to 0.16 per 10,000 discharges if the definition of mucormycosis was relaxed to not require the use of amphotericin B or posaconazole. The median length of stay was 17 days, with 23% dead at discharge; readmission rates were high, with 30 and 37% of patients readmitted within one and three months of discharge, respectively. The average cost per hospital stay was $112,419, and the average per diem cost was $4,096. Conclusions The study provides a recent estimate of the prevalence and burden of mucormycosis among hospitalized patients. The high clinical and economic burden associated with mucormycosis highlights the importance of establishing active surveillance and optimizing prophylactic and active treatment in susceptible patients.

Abstract
OBJECTIVE In the phase III SECURE trial, isavuconazole was non-inferior to voriconazole for all-cause mortality for the primary treatment of invasive mold disease (IMD) caused by Aspergillus spp. and other filamentous fungi. This analysis assessed whether hospital resource utilization was different between patients treated with isavuconazole vs voriconazole in SECURE. METHODS The analysis population comprised adults with proven/probable/possible IMD enrolled in SECURE. The primary endpoint was hospital length of stay (LOS) in the overall trial population. Patients were also stratified by estimated glomerular filtration rate-modification of diet in renal disease category (< 60 mL/min/1.73 m(2) [moderate-to-severe impairment] and ≥60 mL/min/1.73 m(2) [mild or no impairment]), body mass index (BMI; <25, ≥25-<30, and ≥30 kg/m(2)), and age (≤45, >45-≤65, and >65 years). RESULTS Data from 516 patients (258 per arm) were evaluated. Overall, median LOS was not statistically significantly different between the isavuconazole (15.0 days) and voriconazole (16.0 days; p = 0.607) arms. Median LOS was statistically significantly shorter in patients with moderate-to-severe renal impairment treated with isavuconazole (9.0 days) vs voriconazole (19.0 days; hazard ratio [HR]: 3.44; 95% confidence interval [CI] = 1.51-7.83). Median LOS was shorter, but not significantly, in patients with a BMI ≥30 kg/m(2) (isavuconazole 13.5 days vs voriconazole 22 days; HR = 1.57; 95% CI = 0.70-3.52) or aged >65 years (isavuconazole 15.0 days vs voriconazole 20.0 days; HR = 1.37; 95% CI = 0.87-2.16). LIMITATIONS As the patient subgroups analyzed were small, sub-group findings should be interpreted with caution in light of the lack of statistical significance for each sub-group-by-treatment interaction. CONCLUSIONS Isavuconazole may reduce hospital LOS in certain subgroups of patients with IMD, especially those with moderate-to-severe renal impairment.

Abstract
BACKGROUND AND OBJECTIVES Robotic-assisted cholecystectomy (RAC) was introduced several years ago. With its more extensive use by surgeons, more information is needed regarding clinical and economic outcomes. METHODS The Nationwide Inpatient Sample from the Health Cost Utilization Project was analyzed using HCUPnet, National Inpatient Sample (NIS) datasets and SAS 9.2 for the years 2010-2011. Queries were made for RAC and laparoscopic cholecystectomy (LC) procedures with a primary diagnosis of gallbladder disease. Overall charges, costs, number of chronic conditions, comorbidities, and length of stay were calculated. RESULTS RAC was $7518, +54 % (p < 0.05), and $4044, +29 % (p < 0.05), more costly compared to LC in 2010 and 2011, respectively. Total costs for RAC decreased by 14.6 % (p = 0.27) between 2010 and 2011, even though RAC was still costlier than LC in 2011. There was no significant difference in the LOS between RAC and LC in either years. Patients undergoing RAC had an increased number of chronic conditions compared to patients undergoing LC in both 2010 and 2011. CONCLUSION LOS of RAC is similar to LC. Cost of RAC remains higher compared to LC although there was reduction in cost of RAC in 2011 versus 2010.

Abstract
Mucormycosis (MCM) is a life-threatening infection that carries high mortality rates despite recent advances in its diagnosis and treatment. The objective was to report 14 cases of mucormycosis infection and review the relevant literature. We retrospectively analyzed the demographic and clinical data of 14 consecutive patients that presented with MCM in a tertiary-care teaching hospital in northern Mexico. The mean age of the patients was 39.9 (range 5-65). Nine of the patients were male. Ten patients had diabetes mellitus as the underlying disease, and 6 patients had a hematological malignancy (acute leukemia). Of the diabetic patients, 3 had chronic renal failure and 4 presented with diabetic ketoacidosis. All patients had rhinocerebral involvement. In-hospital mortality was 50%. All patients received medical therapy with polyene antifungals and 11 patients underwent surgical therapy. Survivors were significantly younger and less likely to have diabetes than nonsurvivors, and had higher levels of serum albumin on admission. The clinical outcome of patients with MCM is poor. Uncontrolled diabetes and age are negative prognostic factors.
