Clinical, demographic, and laboratory characteristics of COVID -19 infection and risk of in-hospital mortality. A single center 4.

Background: Despite advances in preventive measures, COVID -19 spread and mortality is continuing due to delay in timely diagnosis. This problem is partly dependent on variations in disease characteristics, distribution of risk factors particularly comorbidities and demographic characteristics of patients. This study aimed to determine the clinical presentation and associated factors of mortality in patients hospitalized with COVID -19 infection.

Evaluation of the effectiveness of crocin isolated from saffron in treatment of burning mouth syndrome: A randomized controlled trial.

Objective: Burning mouth syndrome (BMS) is a debilitating disorder with few limited treatment modalities. Because of the proven association between BMS symptoms, and depression and anxiety, treatment modalities that alleviate the two latter etiologic factors can be clinically effective. Thus, owing to the antidepressant and potential analgesic effects of crocin (as an active constituent of saffron), the present study was performed to compare the effect of crocin and citalopram (as control) on BMS symptoms and depression/anxiety in patients with BMS.

Dialysis Catheter-related Bloodstream Infections in Patients Receiving Hemodialysis on an Emergency-only Basis: A Retrospective Cohort Analysis.

Background: An estimated 6500 undocumented immigrants with end-stage renal disease (ESRD) live in the United States. Those living in states that do not provide undocumented immigrants scheduled hemodialysis receive intermittent hemodialysis only when life-threatening conditions arise. Little is known about catheter-related bloodstream infections (CRBSIs) in this population.

The staining effect of different mouthwashes containing nanoparticles on dental enamel.

Background: This study aimed to evaluate the effects of several mouthwashes containing nanoparticles on discoloration of dental enamel, and compare the results with that of 0.2% chlorhexidine (CHX).

Material And Methods: Sixty intact premolars were randomly assigned to six groups.
