Purpose: Emergency departments (EDs) are a vital component of the United States healthcare system and care for over 130 million patient visits annually. Nonurgent ED visits can contribute to crowding, delays in care, and adverse effects. Many high-utilizing ED patients may present with complex medical, behavioral, and social needs that are not necessarily emergent or urgent in nature.

The classical amyloid cascade hypothesis postulates that the aggregation of amyloid plaques and the accumulation of intracellular hyperphosphorylated Tau tangles, together, lead to profound neuronal death. However, emerging research has demonstrated that soluble amyloid-β oligomers (SAβOs) accumulate early, prior to amyloid plaque formation. SAβOs induce memory impairment and disrupt cognitive function independent of amyloid-β plaques, and even in the absence of plaque formation.

This paper analyzes the technical assistance program for research and fishery development, implemented by the Food and Agriculture Organization (FAO) in Brazil, between 1955 and 1978. We argue what were the motivations of the developed countries, the FAO and Brazil to mobilize this knowledge and how the socio-institutional support for its achievement was built. Following the itinerary of experts and attending to the characteristics of the field of fishing biology, we show how the Brazilian field of research, policies and fishing activity were built simultaneously.

Introduction: Modeling supporting recommendations for colonoscopy and stool-based colorectal cancer (CRC) screening tests assumes 100% sequential participant adherence. The impact of observed adherence on the long-term effectiveness of screening is unknown. We evaluated the effectiveness of a program of screening colonoscopy every 10 years vs annual high-sensitivity guaiac-based fecal occult blood testing (HSgFOBT) using observed sequential adherence data.
