High prevalence of CTX-M-1 group in ESBL-producing enterobacteriaceae infection in intensive care units in southern Chile

Braz. j. infect. dis; 23 (2), 2019
ABSTRACT Enterobacteria-producing extended-spectrum β-lactamases (ESBL) play an important role in healthcare infections, increasing hospitalization time, morbidity and mortality rates. Among several ESBLs that emerge from these pathogens, CTX-M-type enzymes had the most successful global spread in d...

T helper type cytokines in sepsis: time-shared variance and correlation with organ dysfunction and hospital mortality

Concentrations of rifampicin in pre-dose samples in patients with pulmonary tuberculosis

Braz. j. infect. dis; 23 (2), 2019
ABSTRACT Rifampicin is used in both phases of treatment for tuberculosis. In chronic use, the short half-life and the self-induction of metabolism can decrease the levels of the drug below the minimal inhibitory concentration. The aim of the study was to investigate whether plasma concentrations of rifam...

Correlation of the aqueous humor total antioxidant capacity, total oxidant status, and levels of IL-6 and VEGF with diabetic retinopathy status

Arq. bras. oftalmol; 82 (2), 2019
ABSTRACT Purpose: We aimed to compare the aqueous humor total oxidant status, total antioxidant capacity, and levels of interleukin-6 and vascular endothelial growth factor between patients with diabetic retinopathy and controls and to correlate these levels with the DR status. Methods: Patients who un...

Effect of contact lenses on ocular biometric measurements based on swept-source optical coherence tomography

Arq. bras. oftalmol; 82 (2), 2019
ABSTRACT Purpose: To determine the reliability of swept- source optical coherence tomography in cases in which soft contact lenses cannot be removed when acquiring biometric measurements. Methods: Eight subjects were included and only one eye per participant was analyzed. Each eye was measured six time...
