Effect of Inappropriate Treatment in Hospitalized Patients with Pyelonephritis Treated with Cefuroxime: A Cohort Study.

The aim of this study was to evaluate the effect of inappropriate therapy in adult patients with community-acquired pyelonephritis caused by receiving empirical treatment with cefuroxime during hospital stay and readmission. A retrospective cohort study was performed. Inappropriate treatment was considered treatment for a nonsusceptible isolate according to the results of the urine culture.

First case of Aspergillus caelatus airway colonization in a Chronic Obstructive Pulmonary Disease patient.

Background: During a cross-sectional study on allergic aspergillosis in Chronic Obstructive Pulmonary Disease patients in Bogotá, Colombia, we reported the case of a 65-year-female patient with GOLD 2011 D classification, presenting dyspnea at the time of visit and aspergillus in repeated sputum cultures.

Methods: The isolate was identified at the section level based on macroscopic and microscopic characteristics and gene sequencing was used for precise molecular identification. Antifungal sensibility was determined by Sensititre YeastOne™ while virulence was assessed using a Galleria mellonella larvae model.

The use of monoclonal antibodies anti-lectin from freshwater prawn Macrobrachium rosenbergii (DeMan, 1879) in the recognition of protein with lectin activity in Decapod's hemolymph.

We determined the cross-reactivity of a monoclonal antibody against the Macrobrachium rosenbergii lectin with proteins in the hemolymph from Procambarus clarkii (Pc), Procambarus americanus (Pa), Litopenaeus setiferus (Ls), and Pseudothelphusa americana (Psa). Crustaceans' hemolymph agglutinated erythrocytes from rat, mouse, guinea pig, and rabbit. Decapods' hemolymph hemagglutinating activity was inhibited by N-acetylated carbohydrates as well as by antibodies.

The effect of sugars and free amino acids from the freshwater prawn Macrobrachium rosenbergii hemolymph on lectin activity and on oxidative burst.

We determined the effect of low molecular weight components (LMWC) from healthy juvenile and adult Macrobrachium rosenbergii hemolymph on lectin activity and oxidative burst (OB) in hemocytes. In an attempt to identify the LMWC that affect the lectin's hemagglutinating activity or oxidative burst, we determined the hemolymph carbohydrates and free amino acids (FAA) concentration. The LMWC (<2000 Da) were obtained after dialysis of the hemolymph.

Participation of serum and membrane lectins on the oxidative burst regulation in Macrobrachium rosenbergii hemocytes.

Using a spectrophotometric NBT reduction assay and phagocytosis, we identified that production of superoxide anions and phagocytic activity of hemocytes from Macrobrachium rosenbergii were significantly higher in the presence of rat, rabbit, and chicken erythrocytes than with human, pig, or horse erythrocytes. Hemocytes stimulated with MrL, MrLMab, or PMA increased 4.7, 5.
