Abstract
PURPOSE Various medications are administered to treat Coronavirus Disease 2019 (COVID-19) infection and prevent its complications. Some medicines have complications and long-term effects, which may mimic other conditions, making precise diagnosis difficult. This report aims to bring to light one such complication, medication-related osteonecrosis of the jaw (MRONJ), secondary to a commonly prescribed medication for preventing lung fibrosis post-COVID-19 infection. METHOD A 33-year-old male reported to our department with the typical clinical and radiological features of Mucormycosis of the upper jaw post-COVID-19 infection. However, on detailed evaluation of his history (controlled diabetic and short duration of steroid therapy) and review of the mycology staining, bacteriology, culture, and histopathological reports, we came to a negative diagnosis for Mucormycosis. The patient was, however, on treatment for the prevention of lung fibrosis with Nintedanib (tyrosine kinase inhibitor) 150 mg twice a day for one month. RESULT In the absence of predisposing factors and negative laboratory findings for mucormycosis, we arrived at a diagnosis of MRONJ, attributable to Nintedanib therapy given to prevent lung fibrosis post-COVID-19 infection. CONCLUSION The use of Nintedanib has recently increased due to the high incidence of lung fibrosis post-COVID-19 infection. However, Nintedanib should be considered a causative agent for osteonecrosis of the jaw in the absence of other obvious predisposing factors. Therefore, Nintedanib must be administered after a thorough consideration of risk factors.

Abstract
OBJECTIVES Microvascular free tissue transfer is routinely used for reconstructing midface defects in patients with malignancy, however, studies regarding reconstructive outcomes in invasive fungal sinusitis (IFS) are lacking. We aim to describe outcomes of free flap reconstruction for IFS defects, determine the optimal time to perform reconstruction, and if anti-fungal medications or other risk factors of an immunocompromised patient population affect reconstructive outcomes. METHODS Retrospective review of reconstruction for IFS (2010-2022). Age, BMI, hemoglobin A1c, number of surgical debridements, and interval from the last debridement to reconstruction were compared between patients with delayed wound healing versus those without. Predictor variables for delayed wound healing and the effect of time on free flap reconstruction were analyzed. RESULTS Twenty-seven patients underwent free flap reconstruction for IFS. Three patients were immunocompromised from leukemia and 21 had diabetes mellitus (DM). Patients underwent an average of four surgical debridements for treatment of IFS. The interval from the last IFS debridement to flap reconstruction was 5.58 months (±5.5). Seven flaps (25.9%) had delayed wound healing. A shorter interval of less than 2 months between the last debridement for IFS and reconstructive free flap procedure was associated with delayed wound healing (Fisher Exact Test p = 0.0062). Other factors including DM, BMI, HgA1c, and bone reconstruction were not associated with delayed wound healing. CONCLUSION Patients with maxillectomy defects from IFS can undergo microvascular-free flap reconstruction with good outcomes while on anti-fungal medication. Early reconstruction in the first 2 months after the last IFS debridement is associated with delayed wound healing. LEVEL OF EVIDENCE 4 Laryngoscope, 134:1642-1647, 2024.

Abstract
Introduction Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has cast a gloom spell on healthcare worldwide, infecting millions of people. Objective The aim of the present study is to determine the prevalence and review the contributing comorbidities and the precipitating factors leading to the emergence of the fungal infections in COVID-19-affected patients. To assess the utility of different laboratory techniques for confirmation of fungal infections. To assess the strengths and limitations of the diagnostic methods. Methods We have studied 252 clinical samples obtained from 121 COVID-positive patients. Results Among the 121 patients clinically diagnosed with fungal infections, 88 had diabetes and were given steroids for treatment ( p -value = 0.001). Ninety-five patients (78.5%) had a positive laboratory diagnosis (either culture positive, potassium hydroxide [KOH]-positive or positive histopathology report). Fungal culture was positive in 75 (61.9%) patients and histopathology report was positive in 62 (51.2%). Histopathology was positive in 7 (5.8%) patients in whom culture and KOH were negative. Conclusion Aggressive treatment methods, administration of immune suppressants, and antibiotics, with an intention to salvage, have made patients susceptible to the benign fungus, causing it to evade the host immunity, thus leading to invasive infections. Applying different laboratory modalities would not only aid in providing fast and valuable information but also help in understanding the pathology which would assist the clinician in selecting the correct treatment for the patient.

Abstract
Coronavirus disease 2019 attributed to severe acute respiratory syndrome has been implicated with life threatening opportunistic infections like mucormycosis. COVID-19 is a hyperferritinemic syndrome and emerging data project the role of iron in the susceptibility and pathogenesis of mucormycosis but whether high ferritin is an indicator of severity of mucormycosis is debated. The study aimed to determine the relationship between serum ferritin levels and the extent of involvement of COVID-19 associated mucormycosis. A hospital based observational study was conducted with a sample size of 70. All biopsy confirmed cases of COVID-19 associated mucormycosis were included. Retrospective data from hospital records prepared at the time of patient admission were retrieved. The imaging data was used to determine the extent of disease involvement and serum ferritin values were analysed. During the study period 40 patients had mild extent mucormycosis and 30 had severe extent. A statistically significant difference was seen in levels of serum ferritin between mild extent mucormycosis and severe extent involvement (p < 0.01). COVID-19 associated Mucormycosis patients tend to have higher serum ferritin values especially in severe extent disease and with active COVID-19 infection along with diabetes mellitus as a potent aggravating factor.

Abstract
Rhinocerebralmucormycosis, is a progressive fungal invasion of a hard palate, paranasal sinuses, orbit, and brain. Post covid the huge number of mucor cases reported in our institute. To combat them a uniform assessment scale was needed as multiple healthcare workers were involved. Thus, a novel linear grading system on nasal endoscopy was developed for the early management of patients to prevent morbidity and mortality. A Prospective study of 650 patients in Epidemic duration from April to June 2021 in a tertiary health center, Central India. Patients subjected to Nasal Endoscopy with 0degree 4 mm Telescope and classified into 5 categories according to the severity of the disease. In a novel grading system, minimum patients were of grade 0, maximum was in Grade I. Maxillary sinus was most commonly involved. This novel grading system on nasal endoscopy makes the management of patients much easier in an epidemic, reducing human errors, morbidity, and mortality of the fulminant disease.

Abstract
Mucormycosis is an invasive opportunistic fungal infection with high mortality, mainly detected in people with COVID-19, especially those with underlying diseases such as diabetes mellitus. Mucormycosis prevalence is 0.005 to 1.7 cases per million inhabitants, and it has been increasing in countries like India and Pakistan. This mycosis can affect different organs, and clinical manifestations reflect the transmission mechanism. Frequent forms are rhino-orbital-cerebral and pulmonary. This disease should be suspected in patients with necrotic injuries on mucous membranes or skin. We present a case of a patient with diabetes mellitus and diagnosed with oral mucormycosis associated with COVID-19.

Abstract
INTRODUCTION Invasive mould infections (IMIs) are a leading cause of death in patients with compromised immune systems. Proven invasive mould infection requires detection of a fungus by histopathological analysis of a biopsied specimen, sterile culture, or fungal DNA amplification by PCR in tissue. However, the clinical performance of a PCR assay on blood samples taken from patients suspected of invasive mould disease has not been fully evaluated, particularly for the differential diagnosis of invasive aspergillosis (IA) and invasive Mucormycosis (IM). OBJECTIVES To assess the diagnostic utility of our previously validated in-house real-time PCR in blood samples for diagnosis of invasive aspergillosis and mucormycosis in patients with suspected invasive mould infection. METHODS All patients with suspected invasive mould infection were prospectively enrolled from May 2021 to July 2021. Conventional fungal diagnosis was performed using tissue and respiratory samples. In-house PCR was performed on blood samples and its diagnostic performance evaluated. RESULTS A total of 158 cases of suspected invasive mould infection were enrolled in the study. The sensitivity and specificity of in-house PCR performed on blood samples was found to be 92.5% and 81.4% respectively for diagnosis of probable IA, and 65% and 84.62% respectively for diagnosis of proven and probable IM. It was also able to detect 3 out of 5 cases of possible IM where no other microbiological evidence of IM was obtained. CONCLUSIONS This assay could be helpful in minimally invasive diagnosis of IMIs for patients in whom invasive sampling is not feasible, especially as a preliminary or screening test. It can help in early diagnosis, anticipating conventional laboratory confirmation by days or weeks. Possible correlation between fungal load and mortality can help in initiating aggressive treatment for patients with high initial fungal load.

Abstract
SUMMARYThe World Health Organization has established a fungal priority pathogens list that includes species critical or highly important to human health. Among them is the order Mucorales, a fungal group comprising at least 39 species responsible for the life-threatening infection known as mucormycosis. Despite the continuous rise in cases and the poor prognosis due to innate resistance to most antifungal drugs used in the clinic, Mucorales has received limited attention, partly because of the difficulties in performing genetic manipulations. The COVID-19 pandemic has further escalated cases, with some patients experiencing the COVID-19-associated mucormycosis, highlighting the urgent need to increase knowledge about these fungi. This review addresses significant challenges in treating the disease, including delayed and poor diagnosis, the lack of accurate global incidence estimation, and the limited treatment options. Furthermore, it focuses on the most recent discoveries regarding the mechanisms and genes involved in the development of the disease, antifungal resistance, and the host defense response. Substantial advancements have been made in identifying key fungal genes responsible for invasion and tissue damage, host receptors exploited by the fungus to invade tissues, and mechanisms of antifungal resistance. This knowledge is expected to pave the way for the development of new antifungals to combat mucormycosis. In addition, we anticipate significant progress in characterizing Mucorales biology, particularly the mechanisms involved in pathogenesis and antifungal resistance, with the possibilities offered by CRISPR-Cas9 technology for genetic manipulation of the previously intractable Mucorales species.

Abstract
Mucormycosis usually occurs in immunocompromised patients or those with uncontrolled diabetes. Along the third wave of SARS-CoV-2, an associated angioinvasive opportunistic infection with Mucor, a life-threatening fungal infection, was rampant and emerging. With an increase in the usage of steroids in the COVID scenario, the rate of mucormycosis did take a rapid and alarming increase in King Edward Memorial Hospital, Pune, India. Any delay in the diagnosis and management of the disease was life-threatening. The most conventional methods to diagnose mucormycosis are microbiological culture and histopathology of the tissue. The microbiological culture method plays an important role in the diagnosis of mucormycosis. However, the technique is labour-intensive, taking seven to eight days. Histopathology leads to false-negative reports if the tissue is not biopsied from representative sites. On the other hand, molecular methods are rapid, reliable, and applicable to different body samples, such as tissue, paraffin-embedded tissue blocks, plasma, and urine. We aimed to use a reverse transcriptase polymerase chain reaction (RT-PCR) method to detect Mucor in plasma samples. Due to a lack of availability of fresh samples, nucleic acid was extracted from the tissue sections of 69 cases diagnosed as Mucor by histopathology. These samples were subjected to RT-PCR using the MucorGenius kit (Pathonostics, Maastricht, Netherlands). A total of 57 tissue samples were sent for culture, and 49% of our cases were positive by culture and equally by RT-PCR. There was 80% sensitivity and 76% specificity between culture and PCR techniques. However, the use of blood/plasma for RT-PCR for early diagnosis of mucormycosis will be the method of choice.

Abstract
Aim: The study aimed to identify quantitative parameters that increase the risk of rhino-orbito-cerebral mucormycosis, and subsequently developed a machine learning model that can anticipate susceptibility to developing this condition. Methods: Clinicopathological data from 124 patients were used to quantify their association with COVID-19-associated mucormycosis (CAM) and subsequently develop a machine learning model to predict its likelihood. Results: Diabetes mellitus, noninvasive ventilation and hypertension were found to have statistically significant associations with radiologically confirmed CAM cases. Conclusion: Machine learning models can be used to accurately predict the likelihood of development of CAM, and this methodology can be used in creating prediction algorithms of a wide variety of infections and complications.

Abstract
BACKGROUND Acute invasive fungal rhinosinusitis (AIFR) is a potentially lethal infection commonly found in immunocompromised patients. It is considered the most aggressive subtype of fungal sinusitis and can lead to severe morbidity and mortality. There was a significant increase in the incidence of AIFR in post-COVID-19 patients compared to AIFR cases before the COVID-19 pandemic. This study aimed to describe the clinical presentation of AIFR associated with COVID-19 illness. METHODS A retrospective study included 22 patients diagnosed with AIFR with a recent COVID-19 infection. RESULTS The most frequent disease associated with AIFR was diabetes mellitus (95.5%). The mycological analysis identified infection caused by Aspergillus species in 72.7% of patients. Along with stabilizing hemodynamic parameters and controlling any comorbidities, all patients in the present study underwent combined surgical debridement followed by antifungal medications. The overall survival rate was 72.7%. The chance of developing a fatal outcome was significantly higher if meningitis presented initially (odds ratio 35.63, p < 0.05). CONCLUSION The presence of meningitis upon initial diagnosis is related to a significantly higher chance of developing a fatal outcome and should be considered, especially in AIFR patients previously treated for COVID-19 infections. Early diagnosis, early use of antifungal agents, aggressive surgical debridement, and control of comorbid conditions remain crucial in managing AIFR. LEVEL OF EVIDENCE: 4

Abstract
INTRODUCTION Mucormycosis is a highly aggressive angio-invasive disease of humans caused by Mucorales fungi. Prior to the COVID-19 pandemic, mucormycosis was a rare mycosis typically seen in immunocompromised patients with hematological malignancies or in transplant recipients. During the second wave of the pandemic, there was a dramatic increase in the disease, especially in India where a unique set of circumstances led to large numbers of life-threatening and disfiguring rhino-orbital-cerebral mucormycosis (ROCM) infections. AREAS COVERED The review examines mucormycosis as a super-infection of COVID-19 patients, and the risk factors for COVID-19-associated mucormycosis (CAM) that drove the ROCM epidemic in India. The limitations of current diagnostic procedures are identified, and the measures needed to improve the speed and accuracy of detection discussed. EXPERT OPINION Despite increased awareness, global healthcare systems remain unprepared for further outbreaks of ROCM. Current diagnosis of the disease is slow and inaccurate, negatively impacting on patient survival. This is most evident in low- to middle-income countries which lack suitably equipped diagnostic facilities for rapid identification of the infecting pathogens. Rapid antigen testing using point-of-care lateral-flow assays could potentially have aided in the quick and accurate diagnosis of the disease, allowing earlier intervention with surgery and Mucorales-active antifungal drugs.

Abstract
Fungi are opportunistic eukaryotic entities often taking advantage of susceptibilities offered by a host due to its immunocompromised status, changed microbiome, or ruptured physical barriers and eventually cause infections. They either invade the skin superficially or are deep-seated. Superficial mycosis affects the skin, hair, and nails inhabiting the outermost layer, stratum corneum. In the present study, we report a case of superficial mycosis (onychomycosis in particular) in a 45-year-old immunocompetent man who was an ex-defense personnel and presently serving as a security guard at the University of Jammu, District Jammu, Jammu and Kashmir, India. The infection evolved 17 years ago and negatively affected the quality of life of the patient. For the identification of the causal agent, direct microscopy, cultural, micro-morphological, molecular characterization (ITS sequencing), and phylogenetic analysis were taken into account. A mucoralean fungal species, Thamnostylum piriforme, was isolated from the fingernails (left hand) of the investigated patient, which represents a new global report as the causal agent of superficial mycosis. In vitro antifungal susceptibility testing showed T. piriforme sensitivity to itraconazole, amphotericin B and ketoconazole while resistance to fluconazole. Careful selection of optimal therapy for fungal infection based primarily on correct identification and antifungal susceptibility testing could provide effective results during treatment against these opportunistic human fungal pathogens.

Abstract
COVID-19-associated rhino-orbital mucormycosis has become a new clinical entity. This study's aim was to evaluate the histopathological and ultramicroscopic morphological aspects of this fungal infection. This was an observational retrospective study on eight patients from three tertiary centers in Romania. The tissue samples collected during functional endoscopic sinus surgery were studied through histopathological examination, scanning electron microscopy, and transmission electron microscopy. In the histopathological examination, the morphological aspects characteristic of mucormycosis in all cases were identified: wide aseptate hyphae with right-angle ramifications, which invade blood vessels. One case presented perineural invasion into the perineural lymphatics. And in another case, mucormycosis-aspergillosis fungal coinfection was identified. Through scanning electron microscopy, long hyphae on the surface of the mucosa surrounded by cells belonging to the local immune system were identified in all samples, and bacterial biofilms were identified in half of the samples. Through transmission electron microscopy, aseptate hyphae and bacterial elements were identified in the majority of the samples. Rhino-orbital-cerebral mucormycosis associated with COVID-19 produces nasal sinus dysbiosis, which favors the appearance of bacterial biofilms. The way in which the infection develops depends on the interaction of the fungi with cells of the immune system.

Abstract
Cutaneous mucormycosis with ischemic complications is a life-threatening condition with high mortality rates, particularly in immunocompromised individuals. The incidence of mucormycosis has increased during the COVID-19 pandemic due to reduced immunity. We present the case of a 17-year-old high school student who experienced a sprained left lower extremity, followed by worsening pain and swelling due to the topical application of unknown local herbs. Eighteen days after the injury, she was admitted to our department in a comatose state with left lower limb ischemia. The patient had a history of uncontrolled diabetes mellitus and displayed a necrotic lesion on her left ankle, suggestive of invasive infectious fungi disease. Diagnostic procedures, including tissue staining and molecular analysis, identified Rhizopus oryzae as the causative organism. Administering amphotericin B yielded marked improvement, but the patient necessitated a mid-thigh amputation to curtail the infection's advance, culminating in her successful discharge post-treatment.

Abstract
BACKGROUND This study aimed to estimate the disease burden and describe the clinical presentation, risk factors, and outcome of CAM in a single centre in Iran. METHODS A case of mucormycosis was defined as one that had clinical and radiological features consistent with mucormycosis along with demonstration of the fungus in tissue via KOH mount/culture/histopathological and molecular examination. RESULTS We report 30 cases of COVID-19 associated mucormycosis (CAM). The results of this study showed the affected age group in the range of 40-79 years (median = 65.5; IQR = 5) with women (16/30, 53%) affected more than men (14/30, 47%). Among the fungi recovered, Rhizopus oryzae had the highest frequency (79%). Out of the 30 patients, 28 (93%) patients were diabetic with 24 (80%) patients having other co-morbidities. Headache followed by retro-orbital pain, proptosis/ptosis and rapid diminution of vision was a common sequence of symptoms reported by the majority of cases. Use of mechanical ventilation (58% vs. 6%, p = 0.003), O2 required (92% vs. 50%, p = 0.024), and development of renal dysfunction during hospital stay (17% vs. 0%, p = 0.041) was significantly higher in non-survivors than survivors. Temperature (C°), PR (pulse rate), mean levels of serum creatinine, BUN, troponin, and neutrophils were significantly higher in non-survivors (p < 0.05). Besides, Albumin and PO2 were also significantly higher in survivors than non-survivors. CONCLUSION Despite medical and surgical treatment, the mortality rate among CAM patients is still high. Thus, concerted efforts of revamping surveillance, diagnosis and management, along with public awareness and patient education, are the requisites for managing COVID-19 and mucormycosis.

Abstract
The second wave of COVID pandemic was associated with an outbreak of Mucormycosis. The mortality rate of Mucormycosis reaches 50-80% in cases with orbital and intracranial extension (Fadda in Acta Otorhinolaryngol Ital 41:43-50, 2021). In this outbreak we found that few of these patients had bacterial invasive sinusitis mimicking fungal sinusitis. Amphotericin the only effective drug against Mucormycosis is highly toxic and expensive and not indicated in bacterial sinusitis. Our aim was to determine the exact etiologic agent, predisposing factors and outcome of treatment of COVID associated invasive sinusitis presenting with orbital complications. It is a retrospective observational study done in 33 patients with orbital complications in COVID associated invasive sinusitis. Demographic details of the patients and clinical presentation were documented. Rhinological examination was done and a nasal swab was taken for KOH mount along with Gram`s stain and Culture and Sensitivity. All Patients underwent radiological evaluation by contrast enhanced computed tomography (CECT) or MRI. Liposomal Amphotericin B was started. Surgical debridement done. Amphotericin-B was stopped in cases reported negative for fungal elements and antibiotics administered for two weeks. Outcome of treatment was documented. A total of 33 patients were included in the study. 48.5% patients were found to have bacterial infection and 27.3% patient's fungal infections and 24.2% mixed infections.Eschar formation, necrotic tissue, erosion of the lamina papyracea was seen in both Klebsiella (33.3%) and Staphylococcal infections (16.6%) similar to Mucor and mixed infections. Persistent opthalmoplegia and deterioration of vision was associated with Mucor and mixed infections. However improvement in proptosis, ptosis, ophthalmoplegia, and vision was observed in cases associated with bacterial invasive sinusitis. Invasive bacterial sinusitis was under diagnosed during second wave of COVID. Identification of invasive bacterial sinusitis can help in de-escalation of treatment.

Abstract
To propose a surgical staging system with management protocol for post-covid Rhino-orbito-cerebral mucormycosis (ROCM) with central skull base osteomyelitis. A prospective cohort study of a total of 193 post-covid ROCM patients was conducted between May 2021 and January 2022 at a tertiary care centre. Patients were assessed radiologically and staged from I to V. Follow up period was 16 months and the surgical outcome in terms of recurrent disease was assessed. A total of 193 patients (129 primary and 64 revision) were studied. Maxilla was found to be the epicenter of anterior disease (69.3%) and pterygoid wedge was noted to be the epicenter of posterior disease (85.6%). More than 65% of our patients, at the time of presentation, presented with involvement of the central skull base. Intracranial disease was noted in 13.9% of patients and the mortality rate was 6.2%. This staging system provides a systematic step-by-step protocol for the management of ROCM, with emphasis on meticulous disease clearance at the central skull base.

Abstract
With the advent of COVID-19, the number of patients diagnosed with mucormycosis has increased, especially in developing countries. The reason behind this increase is that COVID-19 causes hypoxia that promotes the growth of fungus. To identify the association between mucormycosis and COVID-19, in critically ill or immunocompromised COVID-19 patients. The literature included in the review was researched from October 1, 2021, to November 1, 2022, by using the Google Scholar database as the search engine. Of the 20 articles included, there were 4 case reports, 2 case series, 10 narrative reviews, and 4 quantitative studies. Mucormycetes growth is caused by several factors, including hyperglycemia owing to previously existing diabetes or excessive use of steroids, increased ferritin levels owing to the inflammatory cascade initiated by COVID-19, and immunosuppression caused by the use of steroids or other immunosuppressive therapy. Reduced white-cell count and activity in COVID-19 leads to increased germination of fungal spores hence developing a catastrophic picture of rhinocerebral mucormycosis. Considering that the hematological patient is frequently treated with cortisone, immunosuppressed due to the underlying condition, but also through the administered therapy, the association with a possible diabetes makes this patient susceptible to developing rhinocerebral mucormycosis during COVID-19 infection. Despite being severe, the association between mucormycosis and COVID-19 is specific and treatable. Development of mucormycosis in hematological patients suffering from severe COVID-19 disease is dangerous, yet not compulsory and can be prevented. Using a common steroid-dose protocol with hyperbaric oxygen and necessary preventive measure reveals the disease as a superadded infection. Hypoxia, poor glycemic control and overuse of steroids or immunosuppressive drugs cause it.

Abstract
Mucormycosis is a rare disease with scarce diagnostic methods for early intervention. Available strategies employing direct microscopy using calcofluor white-KOH, culture, radiologic, and histopathologic testing often are time-intensive and demand intricate protocols. Nucleic Acid Amplification Test holds promise due to its high sensitivity combined with rapid detection. Loop-mediated isothermal amplification (LAMP) based detection offers an ultrasensitive technique that does not require complicated thermocyclers like in polymerase chain reaction, offering a straightforward means for improving diagnoses as a near-point-of-care test. The study introduces a novel magnetic nanoparticle-based LAMP assay for carryover contaminant capture to reduce false positives. Solving the main drawback of LAMP-based diagnosis techniques. The assay targets the cotH gene, which is invariably specific to Mucorales. The assay was tested with various species of Mucorales, and the limit of detections for Rhizopus microsporus, Lichtheimia corymbifera, Rhizopus arrhizus, Rhizopus homothallicus, and Cunninghamella bertholletiae were 1 fg, 1 fg, 0.1 pg, 0.1 pg, and 0.01 ng, respectively. This was followed by a clinical blindfolded study using whole blood and urine samples from 30 patients diagnosed with Mucormycosis. The assay has a high degree of repeatability and had an overall sensitivity of > 83%. Early Mucormycosis detection is crucial, as current lab tests from blood and urine lack sensitivity and take days for confirmation despite rapid progression and severe complications. Our developed technique enables the confirmation of Mucormycosis infection in < 45 min, focusing specifically on the RT-LAMP process. Consequently, this research offers a viable technique for quickly identifying Mucormycosis from isolated DNA of blood and urine samples instead of invasive tissue samples.

Abstract
Mucormycosis presents a formidable challenge to clinicians and researchers. Animal models are an essential part of the effort to decipher the pathogenesis of mucormycosis and to develop novel pharmacotherapeutics against it. Diverse model systems have been established, using a range of animal hosts, immune and metabolic perturbations, and infection routes. An understanding of the characteristics, strengths, and drawbacks of these models is needed to optimize their use for specific research aims.

Abstract
In India, the incidence of mucormycosis reached high levels during 2021-2022, coinciding with the COVID-19 pandemic. In response to this, we established a multicentric ambispective cohort of patients hospitalised with mucormycosis across India. In this paper, we report their baseline profile, clinical characteristics and outcomes at discharge. Patients hospitalized for mucormycosis during March-July 2021 were included. Mucormycosis was diagnosed based on mycological confirmation on direct microscopy (KOH/Calcofluor white stain), culture, histopathology, or supportive evidence from endoscopy or imaging. After consent, trained data collectors used medical records and telephonic interviews to capture data in a pre-tested structured questionnaire. At baseline, we recruited 686 patients from 26 study hospitals, of whom 72.3% were males, 78% had a prior history of diabetes, 53.2% had a history of corticosteroid treatment, and 80% were associated with COVID-19. Pain, numbness or swelling of the face were the commonest symptoms (73.3%). Liposomal Amphotericin B was the commonest drug formulation used (67.1%), and endoscopic sinus surgery was the most common surgical procedure (73.6%). At discharge, the disease was stable in 43.3%, in regression for 29.9% but 9.6% died during hospitalization. Among survivors, commonly reported disabilities included facial disfigurement (18.4%) and difficulties in chewing/swallowing (17.8%). Though the risk of mortality was only 1 in 10, the disability due to the disease was very high. This cohort study could enhance our understanding of the disease's clinical progression and help frame standard treatment guidelines.

Abstract
The occurrence of mucormycosis has been observed in individuals with COVID-19. However, there is limited information on the epidemiological factors, presentation, diagnostic certainty, and outcome of this infection in children. PubMed, MEDLINE, Scopus, Embase, Web of Science, LitCovid, and back-references of the identified manuscripts were systematically searched from December 2019 to March 2023. We have identified 14 cases of pediatric mucormycosis in patients with COVID-19. The median age of patients was 10.7 years. Among these cases, 10 were associated with active COVID-19. In 7 cases, the patients had pre-existing diabetes mellitus and concomitant diabetic ketoacidosis. Corticosteroids were administered to treat COVID-19 in 7 of the patients. The most common clinical presentation of the disease was rhino-orbital cerebral mucormycosis. Seven patients died (50%). Given the high mortality rate, clinicians should maintain a high level of clinical suspicion of mucormycosis in pediatric patients with COVID-19.

Abstract
Mucormycosis is a fungal infection caused by moulds from the Mucorales order. Concerns have been mounting due to the alarming increase in severe morbidity and mortality associated with mucormycosis during the COVID-19 pandemic. This condition, known as COVID-19-associated mucormycosis (CAM), has been linked to various environmental, host-related, and medical factors on a global scale. We have categorized the most significant potential risk factors for developing mucormycosis in individuals with a previous history of coronavirus infection into 10 major categories. These categories include acute hyperglycemia, the impact of cytokine release, immune response deficiencies in COVID-19 patients, microvasculopathy and dysfunction of endothelial cells, imbalances in iron metabolism, metabolic acidosis, organ damage resulting from COVID-19, underlying health conditions (such as diabetes), environmental factors, and medical treatments that can be iatrogenic in nature (such as inappropriate glucocorticoid use). Many of these factors can lead to potentially life-threatening infections that can complicate the treatment of COVID-19. Physicians should be vigilant about these factors because early detection of mucormycosis is crucial for effective management of this condition.

Abstract
Background The second wave of the coronavirus disease 2019 (COVID-19) pandemic recorded a surge in rhino-orbital-cerebral mucormycosis (ROCM) infection in COVID-19-positive patients with diabetes and on concomitant steroid therapy. The rapidly progressive and devastating nature of the disease necessitated prompt diagnosis and early intervention to improve patient outcomes. Histopathology and fungal culture remain essential tools; however, these investigations have long and variable turn-around times (TATs) and may delay the initiation of treatment. Frozen section is not widely available and should be avoided in COVID-19-positive cases due to the risk of aerosol production and droplet exposure. In cases with high clinicoradiologic suspicion for mucormycosis, imprint cytologic evaluation provides a rapid diagnosis. Familiarity with fungal cytomorphology, awareness of morphologic pitfalls, and implementation of a standardized reporting format aid in diagnostic accuracy. Method Eighteen COVID-19-positive patients, who were admitted to our hospital with clinical suspicion of mucormycosis during June and July 2021, were included in the study. We used nasal or oral imprint cytology for the initial, rapid detection of Mucor. Cytology findings were correlated with histopathology and fungal culture results. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. Results The sensitivity, specificity, PPV, and NPV were 100%, 100%, 100% and 100%, respectively. Conclusion This study showed that imprint cytology can be a rapid, cost-effective, first-line diagnostic modality in Mucor diagnosis.

Abstract
Background In the COVID-STEROID 2 trial there was suggestion of heterogeneity of treatment effects (HTE) between patients enrolled from Europe vs. India on the primary outcome. Whether there was HTE for the remaining patient-centred outcomes is unclear. Methods In this post hoc analysis of the COVID-STEROID 2 trial, which compared 12 mg vs. 6 mg dexamethasone in adults with COVID-19 and severe hypoxemia, we evaluated HTE by geographical region (Europe vs. India) for secondary outcomes with analyses adjusted for stratification variables. Results are presented as risk differences (RDs) or mean differences (MDs) with 99% confidence intervals (CIs) and P-values from interaction tests. Findings There were differences in mortality at day 28 (RD for Europe -8.3% (99% CI: -17.7 to 1.0) vs. India 0.1% (99% CI: -10.0 to 10.0)), mortality at day 90 (RD for Europe -7.4% (99% CI: -17.1 to 2.0) vs. India -1.4% (99% CI: -12.8 to 9.8)), mortality at day 180 (RD for Europe -6.7% (99% CI: -16.4 to 2.9) vs. India -1.0% (99% CI: -12.3 to 10.3)), and number of days alive without life support at day 90 (MD for Europe 6.1 days (99% CI: -1.3 to 13.4) vs. India 1.7 days (99% CI: -8.4 to 11.8)). For serious adverse reactions, the direction was reversed (RD for Europe -1.0% (99% CI: -7.1 to 5.2) vs. India -5.3% (99% CI: -16.2 to 5.0). Interpretation Our analysis suggests higher dose dexamethasone may have less beneficial effects for patients in India as compared with those in Europe; however, the evidence is weak, and this could represent a chance finding. Funding None for this analysis. The COVID STEROID 2 trial was funded by The Novo Nordisk Foundation and supported by Rigshospitalet's Research Council.

Abstract
Aim of the Study Mucormycosis is a rare invasive and fatal fungal infection and its resurgence in coronavirus disease 2019 (COVID-19) patients has been a matter of grave concern. It is essentially a medical disease, but surgical debridement of necrotic tissues is of paramount importance leading to severe craniofacial deformities. In this case series, we present our experience with the feasibility of early reconstruction after surgical debridement. Case Series As a Dedicated COVID Center (DCH), the institute received the largest population of COVID-19 mucormycosis patients from the entire eastern region of the country between May 2021 and August 2021. More than 5,000 COVID-19 were admitted out of which 218 patients were diagnosed with mucormycosis. Nine patients, seven males and two females, with a mean age of 39 years with craniofacial mucormycosis underwent debridement and early reconstructions (2-4 weeks from first debridement and start of antifungal therapy) with free and pedicled flaps. All flaps survived and showed no evidence of recurrence. The average time of the early reconstruction after surgical debridement was 1.7 weeks once the course of systemic amphotericin B was received. Conclusion After aggressive surgical resection and a short course of antifungal therapy, early reconstruction can be done safely based on clinical criteria, as long as there is no evidence of hyphae invasion on wound edges in the intraoperative pathology examination.

Abstract
Coronavirus disease 2019 (COVID-19) is often linked to a broad range of opportunistic bacterial and fungal infections. The second wave of the COVID-19 pandemic has witnessed an unprecedented surge in mucormycosis cases, predominantly in India, while the disease remained relatively rare in Europe. The authors describe the case of a 62-year-old female patient admitted to the hospital for consolidation therapy with chemotherapy as a part of the treatment protocol for acute myeloid leukemia. During hospitalization, she was diagnosed with nosocomial COVID-19, which later progressed to respiratory deterioration. COVID-19 with bacterial superinfection was presumed, leading to the initiation of empirical antibiotic therapy. A bronchoscopy was performed several days later due to a lack of improvement, revealing an infection by the Rhizopus microsporus complex. Despite antifungal treatment, the patient experienced an unfavorable clinical course and ultimately died. Given the high index of suspicion required to diagnose pulmonary mucormycosis, which can lead to delays in appropriate treatment and increase the burden of disease, the authors are aiming to enhance its awareness.

Abstract
AIM Mucormycosis is a rare human infection associated with Mucorales, a group of filamentous moulds found in different environmental niches. Its oral manifestations may occur in the mandible and tongue despite being rare. We aimed to systematically review the data on clinical manifestations, risk factors, diagnostic approaches, treatment options, and outcomes of mandibular and tongue mucormycosis. METHODS An electronic search of articles published between January 1975 and November 2022 in PubMed, Web of Science, and EMBASE databases was performed. A total of 22 articles met the inclusion criteria and reported 27 cases of oral mucormycosis in total. RESULTS Fourteen patients had mandibular mucormycosis signs unrelated to COVID-19 infection, 6 had SARS-CoV-2-related mandibular mucormycosis, and 6 had manifestations in the tongue. All published case reports during the COVID-19 pandemic were from India. Patient ages ranged from 4 months old to 82 years, and most patients had important comorbidities, such as blood dyscrasias related to immune deficiency and uncontrolled type 2 diabetes mellitus. The signs and symptoms of mandibular and tongue mucormycosis varied from dental pain, loose teeth, and nonhealing sockets to dysphagia and paraesthesia of the lip. Some patients also reported trismus, draining sinus tract, and facial pain. The diagnosis of oral mucormycosis was based on a combination of clinical, radiographic, and histopathologic findings by demonstrating fungal hyphae in tissue specimens. In most cases, mucormycosis was managed with systemic amphotericin B, strict glycaemic control, and aggressive surgical debridement of infected tissue, minimising the progression of the fungal infection and thus improving the survival rate. In some cases, combined antifungal therapy, antibiotic therapy, and chlorhexidine mouthwashes were used successfully. CONCLUSIONS Recognition of the signs and symptoms by oral care providers is pertinent for the early diagnosis and treatment of tongue and mandibular mucormycosis, and providers should be aware of the possibility of this opportunistic fungal infection in patients with COVID-19. A multidisciplinary approach is recommended for the management of this lethal infection.

Abstract
BACKGROUND Bacterial and fungal superinfections are commonly reported in patients with coronavirus disease 2019. CASE PRESENTATION We report the first case of brain and intramedullary abscesses caused by Pseudomonas aeruginosa and a rare case of brain abscesses caused by Aspergillus fumigatus in two post-coronavirus disease 2019 patients. The first patient-34-year-old Iranian woman-presented with weakness of the left upper limb, headaches, and lower limb paresthesia. She had a history of undiagnosed diabetes and had received corticosteroid therapy. The second patient-45-year-old Iranian man-presented with right-sided weakness and had a history of intensive care unit admission. Both patients passed away despite appropriate medical therapy. CONCLUSION The immune dysregulation induced by coronavirus disease 2019 and its' treatments can predispose patients, especially immunosuppressed ones, to bacterial and fungal infections with unusual and opportunistic pathogens in the central nervous system. Pseudomonas aeruginosa and Aspergillus fumigatus should be considered as potential causes of brain infection in any coronavirus disease 2019 patient presenting with neurological symptoms and evidence of brain abscess in imaging, regardless of sinonasal involvement. These patients should get started on appropriate antimicrobial therapy as soon as possible, as any delay in diagnosis or treatment can be associated with adverse outcomes.

Abstract
Introduction Amid the second wave of COVID 19 India witnessed a surge of mucormycosis cases. This worsened the already existing health emergency. India a diabetic capital had all the favourable factors to support the growth of black fungus. This study was conducted with objectives of ascertaining patient characteristics, clinical type of mucormycosis, predisposing factors, predictors of survival and long term outcome of survivors. Materials and methods An ambispective study of COVID 19 associated mucormycosis patients admitted in mucor ward of tertiary care hospital between May 2021- August 2021 was done. Study was approved by Institute Ethical Committee. Demographic characteristics, presence of risk factors, clinical sign and symptoms, mode of diagnosis, treatment given, final outcome and long term follow up for a period of 1 year from discharge was done. Results 367 CAM patients were included in the study. 72.5%(n = 266) were men and 27.5% (n = 101) were females. Mean age group was 51.3 years (SD 12.4 years). Most important comorbidity was diabetes( n = 320,87.2%), followed by cardiovascular disease (n = 68, 18.5%) and hypertension (n = 58,15.8%). Other predisposing factors were use of oxygen (n = 367,100%), antibiotics( n = 213,58%) and steroids (n = 272, 74.1%). Dexamethasone was the most commonly used steroid (n = 218,59.4%). Rhino orbital cerebral mucormycosis was the most common type. 83.7% patients (n = 307) survived and 16.3% (n = 60) succumbed to illness. Kaplan Meir survival analysis curve showed use of insulin (p = 0.025), early debridement ( p < 0.05) significantly increased survival rate. Similarly patients with lesions involving, face (p < 0.05) and nose (p = 0.014) had much better outcome as compared to disseminated forms. Only 96 patients remained in follow up. Of these patients no significant alteration in metabolic profile was noted and they remained euglycemic on oral hypoglycaemics. Conclusion Early debridement and insulin use are keys to improved survival. Oxygen, Steroids and antibiotics are the risk factors for mucormycosis. Diabetes is the most important comorbidity.

Abstract
PURPOSE To evaluate factors associated with the occurrence of ROCM in COVID-19 patients and to compare its related parameters and outcomes between active and recovered COVID-19 groups. METHODS A total of 35 patients of ROCM associated with COVID-19 (active and post-COVID-19) were included. This is an ambispective study with retrospective medical records review for COVID-19 analysis and prospective assessments of ROCM-associated COVID-19 during the second wave of the COVID-19 pandemic. The demographic data, clinical parameters, and outcome were recorded on MS excel sheet, and various parameters were compared between active and recovered COVID-19 groups. RESULTS ROCM in recovered COVID-19 group was higher (57.1%) as compared to active COVID-19 (42.9%) (P = 1.00). High occurrence of ROCM was seen in those who had a history of hospitalization due to severity of COVID-19 (n 33, 94.28%), oxygen support (77.14), and received systemic steroids (82.9%). The most common comorbidity was diabetes mellitus (82.9%), and new-onset hyperglycemia was noticed in 17.1% of patients. Exenteration (28.6%) was performed in severe cases who had stage IV ROCM, bilateral, and CNS involvement (RR = 7.2, 95% CI: 2.91 to 18.00). The risk of globe exenteration was 1.35 (0.7-2.29) times higher in recovered COVID-19 group, and mortality was 1.76 (0.72-3.36) times higher in active COVID-19 group. CONCLUSION Monitored use of systemic steroids and the prompt management of hyperglycemia in COVID-19 patients are important factors for favorable outcomes with reference to globe salvage and life-saving in ROCM associated with COVID-19. Even recovered COVID-19 patients should be observed for persistent hyperglycemia and occurrence of ROCM.

Abstract
BACKGROUND There was an upsurge in rhino-orbital-cerebral mucormycosis (ROCM) during the second wave of the COVID-19 pandemic in India. Histopathological examination of the biopsies witnessed greater tissue invasion in these cases. The present study aimed to evaluate the histopathological scoring system in the severity assessment and to compare the scores between ROCM that required orbital exenteration (cases) and those that were treated conservatively (controls). MATERIAL AND METHODS A retrospective study was conducted to analyze the histopathological features using a scoring system in patients diagnosed with mucormycosis on sino nasal biopsies. The scoring was based on the following parameters: the extent of necrosis (score 1 <50% and score 2 >50%), degree of angioinvasion (score 1 <3 vessels in 10 fields and score 2 > 3 vessels in 10 fields), degree of inflammation (mild, moderate or severe), and fungal load(score 1 to 4), based on which three grades (I to III) were given. The scores were compared between the case group and the control group. The data obtained were analyzed statistically. RESULTS The study included 40 controls and 10 cases. The median age of patients in the control group was 52 with 82.5%males (n = 43) and 17.5 % females (n = 7) while in the case group, the median age was 51 years, and all were males. The predominant inflammatory response was of mixed suppurative type (70 %, n = 28). The degree of necrosis was scored 2 in 57.5 % (n = 23) of controls and 70 %(n = 7) in the case group. All the samples in the case group showed scores of 2 for angioinvasion and scores of 3 and 4 for fungal load. There was a statistically significant difference in the degree of necrosis, angioinvasion, the severity of neutrophilic infiltrates, and fungal load between the cases and controls (p-value <0.05). CONCLUSION The present study analyses the predictive role of histopathology in invasive mucormycosis. Higher fungal load, degree of angioinvasion, and the absence of granulomas are associated with advanced disease in sinonasal mucormycosis. The study findings recommend incorporating the histopathological scoring criteria in evaluating patients with sinonasal mucormycosis.

Abstract
In this study, we attempt to look at the various presentations, comorbidities and association of the recent epidemic of rhino-orbital cerebral mucormycosis with Covid-19 in central India. A prospective study of 612 patients diagnosed with mucormycosis from April to July 2021. Detailed history was taken and thorough clinical examination was done. The relation of mucormycosis with Covid-19 and other morbidities was studied. Nasal endoscopy, imaging and management findings were tabulated and analyzed. Male predominance of the disease was noted. The most common age group affected was found to be 41-50 years group having 33.1% of all patients. 83.2% patients had history of Covid-19 infection. Majority of the patients (41.6%) had mucormycosis symptoms within 1 month of Covid-19 symptom onset. Nasal symptoms predominated with 61.1% patients having one or more of the several nasal symptoms. Most common comorbidity was diabetes mellitus (75.8% cases). Nasal and sinus debridement was performed in 584 patients (95.4%). Mucormycosis turned into a widespread epidemic during the second wave of Covid-19 in India. Diabetes mellitus was the most common associated comorbidity that increased the risk of mucormycosis in patients with history of Covid-19 infection. A high index of suspicion in patients presenting with early symptoms in the context of Covid-19, along with prompt diagnosis using radiological, endoscopic and microbiological tools will help reduce mortality to a great extent. Mainstay of treatment is aggressive surgical and medical management, controlling comorbidities and adequate post-operative care.

Abstract
BACKGROUND Identifying early predictors of severe Covid-19 associated mucormycosis (CAM) can help improve management and treatment outcomes. OBJECTIVES Primary: To identify clinical and radiological predictors of disease severity in CAM. Secondary: To describe patterns of central nervous system (CNS) involvement in CAM. METHODS A total of 71 patients with CAM were included in the study. Based on the anatomical extent of involvement on MRI, patients were divided into three groups: Sinus (paranasal sinuses), Orbit (orbital spread), and CNS (CNS spread). Clinical parameters and radiological patterns of involvement of sinuses and extra sinus spaces were studied between the three groups. Patterns of CNS involvement were also described. RESULTS A shorter time lag between COVID-19 infection and CAM, as well as high HbA1C levels, were found to be associated with severe disease. Involvement of the sphenoid, ethmoid and frontal sinuses, T1 hyperintense signal in the sphenoid, as well as bony involvement of the sphenoid sinus, were significantly associated with severe disease. Extra-sinus spread into pre/retroantral space, pterygopalatine fossa, and masticator spaces were also significantly associated with a severe disease course. The most common pattern of CNS spread was cavernous sinus involvement, followed by pachymeningeal spread and cranial nerve involvement. CONCLUSION Early identification of the above-described predictors in patients presenting with CAM can help detect those at risk for developing severe disease. A longer duration of amphotericin, combined with a more aggressive surgical approach in selected cases, may lead to better long-term outcomes.

Abstract
Background Mucormycosis is an aggressive opportunistic fungal infection that afflicts patients with severe underlying immunosuppression, uncontrolled hyperglycemia and/or ketoacidosis, iron overload, and occasionally healthy patients who are inoculated with fungal spores through traumatic injuries. The epidemiology of mucormycosis has changed after the COVID-19 pandemic, with mucormycosis becoming the most common and the fatal coinfection. Methods In a retrospective, cross-sectional study, 82 hospitalized patients with a definite diagnosis of mucormycosis were reported from 2007 to 2021 in a referral, tertiary care center in Tehran, Iran. Results The number of post-COVID cases increased 4.6 times per year, with 41.5% of patients admitted during the two years of the pandemic. Mucormycosis was more common in women (57.3%), and the most common underlying diseases were diabetes (43.7%), both COVID-19 and diabetes (23.2%), cancer (11%), rheumatic diseases (7.3%), COVID-19 without other underlying diseases (6.1%), and transplantation (4.9%). Rhino-orbito-cerebral Mucormycosis (54.9%) followed by Sino-orbital infection (23.2%) was the most common presentation. There was a significant relationship between the use of immunosuppressive agents and the development of Mucormycosis (P<0.005) The average mortality was 41.5%, but this ratio decreased to 35% during the pandemic era. Conclusion The COVID-19 pandemic caused a 4.6-fold increase in the number of mucormycosis patients, and there was a significant relationship between hyperglycemia, corticosteroid use, and mucormycosis. The death rate during the COVID-19 pandemic has decreased by 6.5%, and during the COVID period, the interval between the arrival of a patient with mucormycosis and the start of the correct treatment was significantly decreased.

Abstract
OBJECTIVE An unprecedented rise in mucormycosis cases; apparently called 'an epidemic within a pandemic' was seen worldwide. Therefore, the following study was conducted to know the epidemiology, underlying risk factors, diagnostic approach, and possible outcome of mucormycosis during the Covid-19 pandemic. METHODS A prospective observational study was conducted on patients with a high index of clinical suspicion of mucormycosis Data about demographics, co-morbidities, laboratory investigations, radiology, management, and outcomes were collected. RESULTS We got 45 cases of proven Rhino-orbital-cerebral-mucormycosis (ROCM) from clinically suspected cases. Covid-19 was the most common underlying risk factor (n = 41, 91.11%) followed by Diabetes mellitus (DM) (n = 39; 86.67%). Steroids and oxygen usage were noted in 53.66% (n = 22) and 41.46% (n = 17) respectively. Among the 51 suspected cases of mucormycosis, 47 were supported by radiodiagnosis. Histopathology diagnosed the highest number of mucormycosis cases (n = 44; 97.78%), followed by KOH examination (n = 36; 80%) and Culture (n = 28; 62.22%). The most common species isolated from the tissue samples was Rhizopus species (n = 17; 60.71%), followed by Mucor species (n = 7; 25%). The mortality rate was 17.14%. CONCLUSION DM, Covid-19, and corticosteroids are the chief underlying risk factor for ROCM. Rhizopus spp. was the most dominant etiological agent. Early diagnosis and management with combined medical & surgical intervention have a better survival rate.

Abstract
Background: Scarce data are available on the neurological presentations of coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) and COVID-19-unrelated rhino-orbito-cerebral mucormycosis (ROCM). This study aimed to compare the neurological presentations and their associated outcomes in patients with CAM and COVID-19-unrelated ROCM. Methods: In December 2021, a case-control analysis was conducted on the CAM (case group) and COVID-19-unrelated ROCM (control group) referrals of one center in Isfahan, Iran. Confirmed CAM patients from January 2020 to December 2021 constituted the case group, and patients with COVID-19-unrelated ROCM from 2016-2019 constituted the control group. Their data were then analyzed using proper (non) parametric tests and generalized linear models (GLM), therein P-value below 0.05 was considered as the criterion of statistical significance, and the SPSS software was used. Results: After retrieving data on 177 patients with mucormycosis, 78 patients with CAM were included as the case group and 72 patients with COVID-19-unrelated ROCM were included as the control group. Neurological presentations suggestive of second, third, and eighth cranial nerve involvement were more prevalent in the CAM group (all with P < 0.05). The mortality rate in the CAM group was 1.9 times that of the controls (P = 0.01), being explained by higher extent of corticosteroid administration among them. Higher age and presentation with gait ataxia, ptosis, and mydriasis were considered to be predictive of poor prognosis in patients with CAM (all with P < 0.05). Conclusion: The neurological manifestations of CAM differ from COVID-19-unrelated ROCM based on the presented results, some of which are associated with poor prognosis. Further replication is warranted to confirm our retrospective analyses.

Abstract
INTRODUCTION Mucormycosis has gained a huge number of cases in the second wave of post COVID-19 infection, which may be attributed to increased awareness, advancement in diagnostic techniques, and an increase in the prevalence of predisposing factors. This study evaluated the pattern, risk factors, and clinical profile of patients with mucormycosis during the second wave of the COVID-19 pandemic. METHODS A prospective observational study was conducted in the Department of Emergency Medicine of a dedicated tertiary care hospital for COVID-19. The Institutional Ethics Committee approved the study. One hundred five patients diagnosed with mucormycosis were included from June 2021 to December 2021. Informed consent was obtained from the patients. Data on demography, clinical features, predisposing factors, co-morbid conditions, and microbiological samples were obtained and analyzed. RESULTS Out of 105 patients, 71 were male, and 34 were female. The patient presented with mucormycosis between the 2nd and 3rd week of post COVID-19 infection. Incidence was mainly seen in patients in their fifties, mostly associated with diabetes mellitus (DM) (53.30%), oxygen administration (80%), and previous use of steroids (45.71%). Predominantly, males were more affected. The most common presentation was headache (50.47%), orbital pain with restricted ocular movement (47.67%), proptosis (42.85%), and diminished vision (41.90%). Rhino-orbital-cerebral mucormycosis (ROCM) was the most common presentation of mucormycosis, while only five cases of pulmonary mucormycosis were found. CONCLUSION ROCM was the most common presentation of mucormycosis between the second and third week of post COVID-19 infection. Diabetes mellitus and inadvertent use of steroids were major predisposing factors. Therefore, a high degree of suspicion and early diagnosis with initiation of treatment is warranted in cases of mucormycosis in post COVID-19 infection.

Abstract
COVID-19 pandemic highlighted the complications of secondary fungal infections that occurred globally in severe cases of coronavirus disease managed in the intensive care units. Furthermore, varied underlying host factors, such as preexisting immunosuppression, the use of immunomodulatory agents, and invasive procedures predisposing lung tissues to fungal colonization and proliferation, caused increased susceptibility to fungal infections in COVID-19 patient populations. These invasive fungal infections directly impact the overall length of hospitalization and mortality. The most commonly reported fungal infections in patients with COVID-19 include aspergillosis, invasive candidiasis, and mucormycosis. An overall worldwide increase in the prevalence of candidiasis and aspergillosis was observed in COVID-19 patients , whereas outbreaks of mucormycosis were mainly recorded from India. Diagnostic challenges and limited antifungal treatment options make secondary fungal infections among COVID-19 patients more burdensome, which results in improper management and increased mortality.

Abstract
We evaluated the activity of amphotericin B, itraconazole, posaconazole, voriconazole and caspofungin against 1468 invasive moulds collected worldwide from 2018 to 2021. Most (>92%) of the Aspergillus spp. isolates were wildtype (WT) to amphotericin B, caspofungin and the azoles. Azole-non-wildtype A. fumigatus rates were higher in Europe (9.5%) and North America (9.1%) than Latin America (0.0%; only 12 isolates) and the Asia-Pacific region (5.3%). Amphotericin B and caspofungin were active against azole-non-wildtype A. fumigatus isolates. Posaconazole and amphotericin B were the most active agents against the Mucorales. Among the less common moulds, several expressed a pan-azole-resistant phenotype; many of these species also showed elevated MIC values (MIC, >2 mg/L) for amphotericin B and caspofungin. Although most isolates of Aspergillus spp. remain WT to the azoles, azole resistance is increasing in both North America and Europe. Amphotericin B and caspofungin exhibit potentially useful activity against azole-resistant A. fumigatus.

Abstract
BACKGROUND During the spread of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) or the coronavirus disease 2019 (COVID-19) pandemic in recent times, an upsurge of invasive fungal infections (IFIs) such as mucormycosis was witnessed by many countries like India. This COVID-19-associated mucormycosis (CAM) has presented as a menace to the already creaking health infrastructure. Clinical manifestations, risk factors, and end clinical outcomes varied for every other region/country. The aim of this study is to delineate and analyze plausible clinical and epidemiological factors and associated predictors of CAM in suspected patients presenting to a tertiary care hospital in Uttarakhand, India, during the second wave of COVID-19 in India. MATERIAL AND METHODS A total of 200 cases of suspected post‑COVID-19 mucormycosis were enrolled. Data were collected taking into account parameters such as hospitalization and ICU admissions during the episode of COVID-19 infection, steroid/antibiotics/oxygen requirement, and comorbidities such as diabetes mellitus, hypertension, or any chronic illness and outcome. RESULTS Participants diagnosed with CAM using KOH examination and fungal culture were analyzed in the study (n=46). The median age of patients included was 48, 73.9% were males, and 26% were females. The major predisposing factor was found to be diabetes mellitus type 2. Our work suggests that the mean duration between COVID-19 episodes and CAM was 11.86 days with a significant statistical association. Oxygen requirement and imprudent use of steroids/antibiotics were also allied with mucormycosis. CONCLUSION The burden of such IFIs is expected to be unveiled in tropical countries during pandemics such as COVID-19, which lead to immunosuppression in masses post-treatment. Comorbidities such as diabetes, chronic kidney disease, and hypertension add to the risk of acquiring other infectious disease. Such times require competent healthcare professionals such as diagnosticians, physicians, and surgeons who are skilled to manage such IFIs timely.

Abstract
Introduction The phenomenon of coronavirus disease 2019 (COVID-19)-related candidiasis is gaining increased attention and acknowledgment as an integral component of the severe consequences of COVID-19. The aim of the present study was to assess the association between Candida albicans and COVID-19 in complete denture wearers. Materials and methods An observational study was conducted on 45 complete denture wearers, who were divided into three groups as follows: Group 1, 15 subjects with mild to moderate COVID-19 infection; Group 2, 15 subjects with severe COVID-19 infection; and Group 3, 15 subjects without COVID-19 infection. Mean colony forming units (CFU) were observed on agar plates containing Sabouraud dextrose in the salivary samples of the participants. Analysis of variance, followed by post-hoc analysis by Tukey's test, was used to compare CFU between the groups. Pearson's correlation coefficient was used to study the correlation between variables. Results The highest average colony-forming units of Candida albicans were observed in Group 2, followed by Group 1, compared to the control group, and a significant (p<0.001) difference was found. A weak positive correlation was found between the age of the patients and the duration of denture usage, as well as between age and the counts of Candida albicans in Groups 1 and 3. This correlation was more pronounced in Group 3. A strong positive correlation was observed in all groups between the Candida albicans count and the duration of denture usage by the patients. Conclusion The association between Candida albicans and denture wear was compounded by the presence of COVID-19. Consequently, the timely identification of Candida albicans infection in patients with COVID-19 is important to establish more efficacious approaches for antifungal treatment and prophylactic interventions.

Abstract
BACKGROUND Sudden upsurge in cases of COVID-19 Associated Mucormycosis (CAM) following the second wave of the COVID-19 pandemic was recorded in India. This study describes the clinical characteristics, management and outcomes of CAM cases, and factors associated with mortality. METHODS Microbiologically confirmed CAM cases were enrolled from April 2021 to September 2021 from ten diverse geographical locations in India. Data were collected using a structured questionnaire and entered into a web portal designed specifically for this investigation. Bivariate analyses and logistic regression were conducted using R version 4.0.2. RESULTS A total of 336 CAM patients were enrolled; the majority were male (n = 232, 69.1%), literate (n = 261, 77.7%), and employed (n = 224, 66.7%). The commonest presenting symptoms in our cohort of patients were oro-facial and ophthalmological in nature. The median (Interquartile Range; IQR) interval between COVID diagnosis and admission due to mucormycosis was 31 (18, 47) days, whereas the median duration of symptoms of CAM before hospitalization was 10 (5, 20) days. All CAM cases received antifungal treatment, and debridement (either surgical or endoscopic or both) was carried out in the majority of them (326, 97.02%). Twenty-three (6.9%) of the enrolled CAM cases expired. The odds of death in CAM patients increased with an increase in HbA1c level (aOR: 1.34, 95%CI: 1.05, 1.72) following adjustment for age, gender, education and employment status. CONCLUSION A longer vigil of around 4-6 weeks post-COVID-19 diagnosis is suggested for earlier diagnosis of CAM. Better glycemic control may avert mortality in admitted CAM cases.

Abstract
Introduction Mucormycosis is a rare opportunistic fungal infection caused by fungi belonging to the Mucorales order and Mucoraceae family. It ranks as the third most prevalent angioinvasive fungal infection, following aspergillosis and candidiasis. This severe infection typically affects individuals with compromised immune systems, including those with hematological malignancies like leukemia and lymphoma, individuals who have undergone stem cell transplants, and people with diabetes mellitus. Individuals in good health are rarely affected, making immunocompromised individuals particularly vulnerable to this potentially fatal fungal disease. The aim of this study was to perform a comparative analysis of survivors versus non-survivors among diabetes patients admitted with mucormycosis. Methodology This was a descriptive observational study. A total of 338 patients were enrolled in the study. The study variables included demographics, COVID-19 infection, diabetes mellitus history, steroid use, use of oxygen support, and steam inhalation. Results Of the total 338 patients enrolled in the study, 253 (74.9%) were male and 85 (25.01%) were female. The number of survivors were 305 (90.2%) and non-survivors were 33(9.8%). The mean age of survivors was 52.50 ± 11.31 and non-survivors was 54.06 ± 8.54 years. Patients who underwent steam inhalation had a higher chance of survival compared to those who did not undergo steam inhalation and this association was statistically significant (p=0.01). Males showed a higher chance of survival (93.7%) as compared to females (80.0%). The associations between oxygen support, steroid use, and COVID-19 infection with the survival status were statistically non-significant. Conclusion There was a strong association between the history of steam inhalation and the outcome of mucormycosis among diabetes patients admitted with mucormycosis. Female patients demonstrated a higher fatality rate than males indicating a significant gender disparity observed in cases. Our findings may help to better identify and treat patients who are at higher risk for severe forms of mucormycosis.

Abstract
Background and Aims A rapid surge in rhino-orbito-cerebral mucormycosis (ROCM) cases was reported during the second wave of COVID, especially in India, needing extensive surgical debridement along with medical management. The present study was planned to observe perioperative anesthesia challenges and outcomes of patients with ROCM during the second wave of the COVID-19 pandemic. The primary objective was to observe intraoperative anesthesia challenges and the secondary objectives were to observe postoperative challenges and outcomes of patients. Material and Methods This was a single-centered, bidirectional (retrospective and prospective) observational study, conducted at a tertiary care center. We enrolled 218 adult patients scheduled for surgical debridement of ROCM under general anesthesia. Demographics, COVID status, comorbid illness, intraoperative challenges (difficult airway, hemodynamic instability, blood loss), and postoperative outcome (postoperative mechanical ventilation, and mortality rate) were noted. Results The majority of the patients were males (71%) and had diabetes mellitus (54%). COVID-associated mucormycosis was seen in 67% and 41% of them received steroids. Post-induction hypotension was noted in 20.6% of patients, and 14.2% had intraoperative hypotension out of which 5.5% required vasopressor support. Difficult mask ventilation and difficult intubation were reported in 7.3% and 6.4% of patients, respectively. No significant difference was found among intraoperative challenges when COVID mucormycosis was compared to non-COVID mucormycosis. Postoperative mechanical ventilation and ICU care were required in 41.3%, whereas mortality was seen in 11.5% of patients. The mortality was significantly more (P = 0.041) in patients with COVID mucormycosis (13%) compared to that with non-COVID mucormycosis (4.2%). Conclusion Diabetic male patients who received steroids during COVID illness are at the highest risk of developing ROCM. Difficult airway and hemodynamic instability, are significant perioperative challenges encountered by anesthesiologists. Postoperative ICU management is crucial for decreasing postoperative morbidity and mortality.

Abstract
The outbreak of a fatal black fungus infection after the resurgence of the cadaverous COVID-19 has exhorted scientists worldwide to develop a nutshell by repurposing or designing new formulations to address the crisis. Patients expressing COVID-19 are more susceptible to Mucormycosis (MCR) and thus fall easy prey to decease accounting for this global threat. Their mortality rates range around 32-70% depending on the organs affected and grow even higher despite the treatment. The many contemporary recommendations strongly advise using liposomal amphotericin B and surgery as first-line therapy whenever practicable. MCR is a dangerous infection that requires an antifungal drug administration on appropriate prescription, typically one of the following: Amphotericin B, Posaconazole, or Isavuconazole since the fungi that cause MCR are resistant to other medications like fluconazole, voriconazole, and echinocandins. Amphotericin B and Posaconazole are administered through veins (intravenously), and isavuconazole by mouth (orally). From last several years so many compounds are developed against invasive fungal disease but only few of them are able to induce effective treatment against the micorals. Adjuvant medicines, more particularly, are difficult to assess without prospective randomized controlled investigations, which are challenging to conduct given the lower incidence and higher mortality from Mucormycosis. The present analysis provides insight into pathogenesis, epidemiology, clinical manifestations, underlying fungal virulence, and growth mechanisms. In addition, current therapy for MCR in Post Covid-19 individuals includes conventional and novel nano-based advanced management systems for procuring against deadly fungal infection. The study urges involving nanomedicine to prevent fungal growth at the commencement of infection, delay the progression, and mitigate fatality risk.

Abstract
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic is still difficult to be controlled. The spread of this virus and the emergence of new variants are considered a great challenge worldwide. Disturbance in infection control guidelines implementation, use of steroids, antibiotics, hospital crowdedness, and repeated use of oxygen masks during the management of critically ill COVID-19 patients lead to an increase in the rate of opportunistic infections. So, patients need to fight both the virus with its different variants and opportunistic pathogens including bacteria and fungi especially patients with diabetes mellitus, malignancy, or those who undergo hemodialysis and receive deferoxamine. During the pandemic, many cases of Mucormycosis associated with COVID-19 infection were observed in many countries. In this review, we discuss risk factors that increase the chance of infection by opportunistic pathogens, especially fungal pathogens, recent challenges, and control measures.

Abstract
Mucormycosis (MCR) is an emerging and frequently lethal fungal infection caused by the Mucorales family, with Rhizopus, Mucor, and Lichtheimia, accounting for > 90% of all cases. MCR is seen in patients with severe immunosuppression such as those with hematologic malignancy or transplantation, Diabetes Mellitus (DM) and diabetic ketoacidosis (DKA) and immunocompetent patients with severe wounds. The recent SARS COV2 epidemy in India has resulted in a tremendous increase in MCR cases, typically seen in the setting of uncontrolled DM and corticosteroid use. In addition to the diversity of affected hosts, MCR has pleiotropic clinical presentations, with rhino-orbital/rhino-cerebral, sino-pulmonary and necrotizing cutaneous forms being the predominant manifestations. Major insights in MCR pathogenesis have brought into focus the host receptors (GRP78) and signaling pathways (EGFR activation cascade) as well as the adhesins used by Mucorales for invasion. Furthermore, studies have expanded on the importance of iron availability and the complex regulation of iron homeostasis, as well as the pivotal role of mycotoxins as key factors for tissue invasion. The molecular toolbox to study Mucorales pathogenesis remains underdeveloped, but promise is brought by RNAi and CRISPR/Cas9 approaches. Important recent advancements have been made in early, culture-independent molecular diagnosis of MCR. However, development of new potent antifungals against Mucorales remains an unmet need. Therapy of MCR is multidisciplinary and requires a high index of suspicion for initiation of early Mucorales-active antifungals. Reversal of underlying immunosuppression, if feasible, rapid DKA correction and in selected patients, surgical debulking are crucial for improved outcomes.
