Background: Primary care providers (PCPs) may modify their antibiotic prescription practices if aware of their potentially damaging impact.
Methods: We conducted a cluster randomized controlled trial at 12 Veterans Affairs community-based outpatient clinics. PCPs at clinics randomized to the intervention group received quarterly antibiotic use reports with feedback about antibiotics prescribed for acute respiratory infections and adverse event letters alerting about infection or antibiotic-resistant gram-negative bacteria among their patients.
Here, the dynamics of inverse tapered granular chains, which are alignments of beads with progressively increasing radii, are investigated. These chains are subjected to harmonic excitation by a moving wall and probed at the tapered end. Intermediate taperings using Ni-Ti (metal) and Teflon (plastic) granules are considered.

In the present study, we used a model of lupus-like cognitive impairment that is initiated when antibodies that crossreact with excitatory neuronal receptors penetrate the hippocampus, causing immediate, self-limited, excitotoxic death of hippocampal neurons, which is then followed by a significant loss of dendritic complexity in surviving neurons. This injury creates a maladaptive equilibrium that is sustained in mice for at least 1 year.

Objective: To determine whether providing NH clinicians with a urinary antibiogram improves empirical antibiotic treatment of urinary tract infections (UTIs).
