question:
Question: Does fibroblast growth factor 8 regulate postnatal development of paraventricular nucleus neuroendocrine cells?
Answer: First, Fgf8 hypomorphy did not eliminate VP and CRH neurons in the mouse PVN, but rather disrupted the postnatal timing of neuropeptide expression onset in PVN neurons. Second, Fgf8 hypomorphy may, in part, be an explanation for affective disorders involving hyperactivity of the HPA axis, such as anxiety.
answer:
yes


question:
Question: Does empiric , broad-spectrum antibiotic therapy with an aggressive de-escalation strategy induce gram-negative pathogen resistance in ventilator-associated pneumonia?
Answer: In our SICU, early, empiric broad-spectrum VAP therapy followed by de-escalation to pathogen-specific agents did not alter antimicrobial resistance and is a valid practice. Further, our compliance with de-escalation practices was higher than published rates.
answer:

no
