The current treatment of Chagas disease is based on monopharmacology where the used drugs have limited efficacy and severe side effects. In order to overcome these limitations, some tools have been described including the development or isolation of new drugs, drug repositioning, and polypharmacology. Here, we review the polypharmacology strategy where compounds belonging to different structural chemotypes were combined in order to affect different biochemical pathways of T. cruzi parasite. Therefore ergosterol biosynthesis inhibitors, anti-inflammatory agents, cardiac dysfunction drugs, trypanothione reductase inhibitors, vitamins, between others, were combined looking for new anti-Chagas treatment. Natural products were also used in the application of this strategy.

Background: The relationship between plasmatic fatty acid (FA) composition and liver fibrosis remains scarce in people living with HIV/AIDS (PLWHA). We aimed to evaluate the association of plasmatic FAs and liver fibrosis in HIV mono-infected individuals.
Methods: This case-control study included PLWHA with liver fibrosis (cases) and randomly selected subjects without fibrosis (controls) from the PROSPEC-HIV study (NCT02542020).

The high plasticity of cells undergoing epithelial-mesenchymal transition (EMT) promotes increased tumor heterogeneity, and its interaction with tumor-associated stromal cells appears to contribute to developing a stemness phenotype. Cells with these characteristics exhibit increased resistance to chemotherapy and radiotherapy, leading to disease relapse and metastasis. Here, we discuss the activation of the Wnt/β-catenin pathway in promoting EMT and stemness within the context of cellular resistance to these therapies.

We hypothesized that melatonin (Mel) supplementation may offer therapeutic benefits for obesity, particularly in women. Therefore, the study evaluated Mel's effects on white adipose tissue (WAT) in diet-induced obese female mice. Four-week-old C57BL/6 females were assigned to either a control diet (C group) or a high-fat diet (HF group) for 6 weeks (n = 20/group).

Advanced heart failure primarily manifests during and after hospitalization for decompensation. Identifying prognostic factors is crucial for distinguishing patients who may benefit from drug therapy from those with end-stage disease. This study aimed to evaluate the prognostic significance of systemic vasoconstriction in patients with decompensated heart failure with a reduced ejection fraction.

Background: Pregnant women constitute a vulnerable population occasionally affected by zoonotic sporotrichosis. Treatment is challenging due to potentially teratogenic oral medications (itraconazole and saturated potassium iodide solution) or lack of clinical experience during pregnancy (terbinafine). Literature is scarce on sporotrichosis and pregnancy, mainly consisting of case reports.
