Association Between Household Deprivation and Living in Informal Settlements and Incidence of Diarrhea in Children Under 5 in Eleven Latin American Cities.

Diarrhea is a leading cause of death in children globally, mostly due to inadequate sanitary conditions and overcrowding. Poor housing quality and lack of tenure security that characterize informal settlements are key underlying contributors to these risk factors for childhood diarrhea deaths. The objective of this study is to better understand the physical attributes of informal settlement households in Latin American cities that are associated with childhood diarrhea.

Evaluation of Microscopic Structure-Function Relationships of PEGylated Small Intestinal Submucosa Vascular Grafts for Arteriovenous Connection.

Vascular grafts are used as vascular access for hemodialysis, the most common renal replacement therapy to artificially clean blood waste after kidney malfunction. Despite that they are widely used in clinical practice, upon implantation, synthetic vasculars show complications such as thrombogenesis, reduced patency rates, low blood pressure, or even complete collapse. In this study, a C-shaped vascular graft was manufactured with small intestinal submucosa (SIS) and modified on the surface and the bulk of the material via conjugation of polyethylene glycol (PEG) to obtain a biocompatible and less thrombogenic vascular graft than the commercially available polytetrafluoroethylene (ePTFE) vascular grafts.
