Epidemiology of invasive candidiasis before and during the COVID-19 pandemic at a hospital in southeastern Brazil.

Introduction: Invasive candidiasis is an important cause of nosocomial infection and recent studies have shown an increase in the number of cases during the coronavirus disease 2019 (COVID-19) pandemic. The present study aimed to evaluate the epidemiology and incidence of invasive candidiasis before and during the COVID-19 pandemic at a reference tertiary hospital in Brazil.

Methodology: A retrospective observational study was performed with 148 patients infected with Candida spp.

Brewer's Spent Grain-Cellulose-Coated Copper Electrode-Based Extended Gate Field-Effect Transistor for Nonenzymatic Glucose Detection toward Diagnosis of Diabetes Mellitus.

The demand for environmentally friendly, reliable, and cost-effective electrodes for glucose sensor technology has become a major research area in the paradigm shift toward green electronics. In this regard, cellulose has emerged as a promising flexible biopolymer solution with unique properties such as biocompatibility, biodegradability, nontoxicity, renewability, and sustainability. Because of their large surface area and porous structure, fibrous cellulose substrates quickly adsorb and disperse analytes at detection sites.

Six-year experience with GM test in hematological patients in a public Brazilian tertiary hospital.

Unlabelled: Invasive fungal infection (IFI) is frequent in patients with hematologic malignancies or submitted hematopoietic stem cell transplantation (HSCT).

Objectives: To evaluate the role of the GM (galactomannan) test in prescribing therapeutic antifungals; to determine invasive aspergillosis (IA) frequency, the factors associated with positive GM test, and the in-hospital mortality.

Methods: We conducted a retrospective observational study including patients aged 18 or over with hematological malignancy or submitted to HSCT.
