Mucormycosis is a life-threatening opportunistic angioinvasive fungal infection. We aimed to describe the frequency, presentations, predictors, and in-hospital outcome of mucormycosis patients in the scope of CoronaVirusDisease-19 (COVID-19) during the third viral pandemic wave. This cross-sectional retrospective study included all patients who fulfilled the criteria of mucormycosis with concurrent confirmed covid19 infection admitted to Assuit University Hospital between March 2021 and July 2021. Overall, 433 patients with definite covid-19 infection, of which 33 (7.63%) participants were infected with mucormycosis. Mucormycosis was predominantly seen in males (21 vs. 12; p = 0.01). Diabetes mellitus (35% vs. 63.6%; p < 0.001), hypertension (2% vs.45.5%; p 0.04), and Smoking (26.5% vs. 54.5%; p < 0.001) were all significantly higher in mucormycosis patients. Inflammatory markers, especially E.S.R., were significantly higher in those with mucormycosis (p < 0.001). The dose of steroid intake was significantly higher among patients with mucormycosis (160 mg vs. 40 mg; p < 0.001). Except for only three patients alive by residual infection, 30 patients died. The majority (62%) of patients without mucormycosis were alive. Male sex; Steroid misuse; D.M.; Sustained inflammation; Severe infection were significant risk factors for mucormycosis by univariate analysis; however, D.M.; smoking and raised E.S.R. were predictors for attaining mucormycosis by multivariate analysis.

Background: As COVID-19 has neither a standard treatment protocol nor guidelines, there are many treatment protocols for anti-inflammatory corticosteroids and anti-coagulations for severe COVID-19 pneumonia patients. This study aimed to assess the most suitable modality in this high-risk group. Methods: A prospective, experimental study design was adopted that included 123 severe COVID-19 pneumonia patients admitted at Assiut University Hospital. Patients were divided into three groups according to a combined corticosteroid and anticoagulants therapy protocol. Group A included 32 patients, group B included 45 patients, and group C included 46 patients. Assessment of cases was conducted according to the treatment type and duration, weaning duration from oxygen therapy, length of hospital and ICU stay, and complications during treatment. Three months follow-up after discharge was performed. Results: the three patient groups showed significant differences regarding the 3-month outcome, whereas Group C showed the highest cure rate, lowest lung fibrosis, and lowest mortality rate over the other two groups. The in-hospital outcome, the development of pulmonary embolism, bleeding, hematoma, acute kidney disease, and myocardial infarction showed a significant difference between groups (p values < 0.05). Mortality predictors among severe COVID-19 patients by multivariable Cox hazard regression included treatment modality, history of comorbid diseases, increased C reactive protein, high neutrophil-lymphocyte ratio, and shorter ICU and hospital stay. Conclusion: the use of combined methylprednisolone and therapeutic Enoxaparin, according to a flexible protocol for COVID-19 patients with severe pneumonia, had two benefits; the prevention of disease complications and improved clinical outcome.

Background: Myocardial blush grading is considered to be a novel tool for assessment of coronary microvasculature and myocardial perfusion in patients undergoing coronary angiography and angioplasty, and its reduction identifies patients at high risk. Our study aimed to evaluate the association between acute insulin resistance and myocardial blush in non-diabetic patients with ST-segment elevation myocardial infarction (STEMI).Methods: Two hundred forty non-diabetic patients with STEMI who underwent primary percutaneous coronary intervention were consecutively recruited. The relationship of homeostasis model assessment—estimated insulin resistance (HOMA-IR) to myocardial blush and in-hospital outcome was investigated.Results: Higher HOMA-IR tertile was observed in obese patients, with hyperinsulinemia, had Killip class &gt;1, with higher CPK-MB level and was correlated to impaired myocardial blush after adjusting for the other confounding risk factors. It was also concluded that higher HOMA-IR was independently associated with no/minimal myocardial blush after STEMI. Moreover, it was founded to be an independent predictor of pulmonary edema and impaired left ventricular systolic function.Conclusion: This study revealed that acute insulin resistance was prevalent in non-diabetic patients with STEMI and was an independent predictor for post-infarction myocardial and microvascular injury and poor in-hospital outcome.Trial Registration: The trial was registered at the registry of Clinicaltrials.gov, ClinicalTrials.gov Identifier: NCT04651842, Date of registration: 2nd December 2020 Registry URL, https://clinicaltrials.gov/ct2/show/NCT04385589?cond=Dapagliflozin+in+diabetic+patients&amp;cntry=EG&amp;draw=2&amp;rank=1.
