Antigenic determinants underlying IgE-mediated anaphylaxis to peanut.

Background: Studies of human IgE and its targeted epitopes on allergens have been very limited. We have an established method to immortalize IgE encoding B cells from allergic individuals.

Objective: To develop an unbiased and comprehensive panel of peanut-specific human IgE mAbs to characterize key immunodominant antigenic regions and epitopes on peanut allergens to map the molecular interactions responsible for inducing anaphylaxis.

Multicomponent Deimplementation Strategy to Reduce Low-Value Preoperative Testing.

Importance: Routine preoperative blood tests and electrocardiograms before low-risk surgery do not prevent adverse events or change management but waste resources and can cause patient harm. Given this, multispecialty organizations recommend against routine testing before low-risk surgery.

Objective: To determine whether a multicomponent deimplementation strategy (the intervention) would reduce low-value preoperative testing before low-risk general surgery operations.

Multidimensional perspectives of geo-epidemiology: from interdisciplinary learning and research to cost-benefit oriented decision-making.

Research typically promotes two types of outcomes (inventions and discoveries), which induce a virtuous cycle: something suspected or desired (not previously demonstrated) may become known or feasible once a new tool or procedure is invented and, later, the use of this invention may discover new knowledge. Research also promotes the opposite sequence-from new knowledge to new inventions. This bidirectional process is observed in geo-referenced epidemiology-a field that relates to but may also differ from spatial epidemiology.

Pathogen delivery route impacts disease severity in experimental Mycoplasma ovipneumoniae infection of domestic lambs.

M. ovipneumoniae is a respiratory pathogen that can cause mild to moderate pneumonia and reduced productivity in domestic lambs. However, studies on both natural and experimental M.
