RESUMO

The tetracycline transactivator (tTA) system provides controllable transgene expression through oral administration of the broad-spectrum antibiotic doxycycline. Antibiotic treatment for transgene control in mouse models of disease might have undesirable systemic effects resulting from changes in the gut microbiome. Here we assessed the impact of doxycycline on gut microbiome diversity in a tTA-controlled model of Alzheimer's disease and then examined neuroimmune effects of these microbiome alterations following acute LPS challenge. We show that doxycycline decreased microbiome diversity in both transgenic and wild-type mice and that these changes persisted long after drug withdrawal. Despite the change in microbiome composition, doxycycline treatment had minimal effect on basal transcriptional signatures of inflammation the brain or on the neuroimmune response to LPS challenge. Our findings suggest that central neuroimmune responses may be less affected by doxycycline at doses needed for transgene control than by antibiotic cocktails at doses used for experimental microbiome disruption.

RESUMO

OBJECTIVE: The aim of this review was to assess pharmacist and pharmacy services being provided and identify opportunities to improve patient satisfaction. METHODS: Studies published between January 2006 and July 2016 examining patient satisfaction with pharmacy and pharmacist services, which were written in English, were identified in PubMed. Studies were excluded if they only looked at pharmacy student-provided services. KEY FINDINGS: A total of 50 studies were ultimately included in the review. Of these studies, 28 examined services traditionally provided by community pharmacists such as dispensing and counseling, while 16 examined a new in-person service being offered by a pharmacy, and the remaining six involved a new technology-assisted service. While study findings were generally positive for patient satisfaction of pharmacy services, several opportunities were identified for pharmacies to improve. CONCLUSION: Overall, patient satisfaction is high across pharmacy services; however, this satisfaction is related to prior patient exposure to services and their level of expectation. Pharmacists have multiple opportunities to improve the services they provide, and there are additional services pharmacists may consider offering to expand their role within the health care system.
