White Paper AGA: An Episode-of-Care Framework for the Management of Obesity-Moving Toward High Value, High Quality Care: A Report From the American Gastroenterological Association Institute Obesity Episode of Care and Bundle Initiative Work Group.

The American Gastroenterological Association acknowledges the need for gastroenterologists to participate in and provide value-based care for both cognitive and procedural conditions. Episodes of care are designed to engage specialists in the movement toward fee for value, while facilitating improved outcomes and patient experience and a reduction in unnecessary services and overall costs. The episode of care model puts the patient at the center of all activity related to their particular diagnosis, procedure, or health care event, rather than on a physician's specific services.

Neutrophil chemotaxis by pathogen-associated molecular patterns--formylated peptides are crucial but not the sole neutrophil attractants produced by Staphylococcus aureus.

The chemotactic migration of phagocytes to sites of infection, guided by gradients of microbial molecules, plays a key role in the first line of host defence. Bacteria are distinguished from eukaryotes by initiation of protein synthesis with formyl methionine. Synthetic formylated peptides (FPs) have been shown to be chemotactic for phagocytes, leading to the concept of FPs as pathogen-associated molecular patterns (PAMPs).

Targeting metalloenzymes: a strategy that works.

Faced with a wealth of antibacterial drug discovery targets as a result of bacterial genomics, we need to carefully select which ones to work with. Choosing bacterial metalloenzymes is one possible approach that can increase the probability of success. Metalloenzymes can be identified through specific motif searches of bacterial genomes.

N-alkyl urea hydroxamic acids as a new class of peptide deformylase inhibitors with antibacterial activity.

Peptide deformylase (PDF) is a prokaryotic metalloenzyme that is essential for bacterial growth and is a new target for the development of antibacterial agents. All previously reported PDF inhibitors with sufficient antibacterial activity share the structural feature of a 2-substituted alkanoyl at the P(1)' site. Using a combination of iterative parallel synthesis and traditional medicinal chemistry, we have identified a new class of PDF inhibitors with N-alkyl urea at the P(1)' site.
