Structural and vascular assessment of the optic nerve head and macula in chronic Chagas disease.

Chagas disease (CD), a parasitic infection, may have ocular repercussions in its cardiologic form, since a history of heart disease of other etiologies already has been established as a risk factor for neuropathies and maculopathies. The aim of the present study was to investigate preclinical structural and vascular optic nerve head (ONH) and macular parameters in patients with chronic CD. Nineteen patients with CD and 19 healthy subjects were evaluated with optical coherence tomography, optical coherence tomography angiography, and Laguna ONhE® software.

Guyton's hemodynamic mosaic: crafting fluid management with precision.

Sheldon Magder's article on applying Arthur Guyton's principles to clinical fluid management provides valuable insights into optimizing hemodynamics in critically ill patients. While emphasizing the role of right atrial pressure (RAP) in assessing cardiac output, challenges arise due to RAP's variable accuracy and the oversimplification of cardiovascular dynamics. Integrating RAP with dynamic assessments and bedside ultrasound can enhance fluid management strategies.

Green synthesis of silver nanoparticles derived from algae and their larvicidal properties to control .

Mosquito vectors such as . are responsible for the transmission of arboviruses that have a major impact on public health. Therefore, it is necessary to search for ways to control these insects, avoiding the use of conventional chemical insecticides that are proven to be toxic to nature.

Dosing of Bacterial Phytase (EC 3.1.3.26) in Laying Hens' Diets.

Despite the acknowledged advancements in the utilization of phytase dosing, limited research has been conducted on commercial laying hens. To assess the effectiveness of doses of exogenous phytase, a total of 320 laying hens aged between 44 and 64 weeks were utilized. These hens were divided into five treatments, which were then distributed using a completely randomized design with eight replicates, each containing eight birds.
