Acute Infusion-Related Side Effects of Amphotericin B Lipid Complex (ABLC) in Oncohematological Patients: Real-World Data from Brazilian Reference Centers.

Introduction: Amphotericin B lipid complex (ABLC) is an effective antifungal agent for treating invasive fungal infections (IFIs) even though its formulation is associated with potential adverse events, including those related to its infusion. This study aimed to analyze the incidence of acute infusion-related side effects (IRSE) associated with ABLC and their relationship with the profile of patients with oncohematological disease admitted in Brazilian reference tertiary hospitals.

Methods: This is an observational retrospective study that included clinical records of patients hospitalized, in a period of 6 years, diagnosed with probable or proved IFI and treated with at least two doses of ABLC.

HSP90 buffers deleterious genetic variations in .

Protein-folding chaperone HSP90 buffers genetic variation in diverse organisms, but the clinical significance of HSP90 buffering in disease remains unclear. Here, we show that HSP90 buffers mutations in the BRCT domain of BRCA1. HSP90-buffered mutations encode protein variants that retain interactions with partner proteins and rely on HSP90 for protein stability and function in cell survival.

Interpolyelectrolyte complexes of a biguanide cationic polyelectrolyte: formation of core/corona nanoparticles with double-hydrophilic diblock polyanion.

Biguanide-based cationic polyelectrolytes are used as key components of interpolyelectrolyte complexes bolstering alginate hydrogel microcapsules employed in cell therapies. Nevertheless, electrostatic complexation of these unique polycations has not been studied before. In this study, the interaction between biguanide condensates and anionic polyelectrolytes with carboxylate groups was studied on a model system of a metformin condensate (MFC) and an anionic diblock polyelectrolyte poly(methacrylic acid)--poly(ethylene oxide) (PMAA-PEO).

[Porto sinusoidal vascular disease: an unusual cause of digestive bleeding].

Portal hypertension (PHT) is defined as an increase in pressure at the level of the portal vein above 5 mmHg, the most common cause being liver cirrhosis. Among the presinusoidal intrahepatic causes of PHT with portal venular involvement, what was traditionally known as idiopathic non-cirrhotic portal hypertension (NCIH) is described, with the requirements of excluding those patients who did not present PHT, as well as those with the presence of liver cirrhosis and thrombosis. portal venous vein (PVT).
