A functional cerebral endothelium is necessary to protect against cognitive decline.

A vascular insult occurring early in disease onset may initiate cognitive decline leading to dementia, while pharmacological and lifestyle interventions can prevent this progression. Mice with a selective, tamoxifen-inducible deletion of NF-κB essential modulator (Nemo) in brain endothelial cells were studied as a model of vascular cognitive impairment. Groups included NemoFl controls and three NemobeKO groups: One untreated, and two treated with simvastatin or exercise. Social preference and nesting were impaired in NemobeKO mice and were not countered by treatments. Cerebrovascular function was compromised in NemobeKO groups regardless of treatment, with decreased changes in sensory-evoked cerebral blood flow and total hemoglobin levels, and impaired endothelium-dependent vasodilation. NemobeKO mice had increased string vessel pathology, blood-brain barrier disruption, neuroinflammation, and reduced cortical somatostatin-containing interneurons. These alterations were reversed when endothelial function was recovered. Findings strongly suggest that damage to the cerebral endothelium can trigger pathologies associated with dementia and its functional integrity should be an effective target in future therapeutic efforts.

Student pharmacist perceived benefit of a sequential training model for health testing.

PURPOSE: This article describes the health testing training process used at Presbyterian College School of Pharmacy and evaluates perceptions of the sequential training model among students in their first, second, and third professional years. EDUCATIONAL ACTIVITY AND SETTING: After observing student deficiencies in the knowledge and skills necessary for performing health tests, despite receiving didactic training within the core curriculum, faculty members searched for supplemental training programs used by other schools of pharmacy. No literature regarding structured programs was found. Consequently, faculty developed test-specific training modules for a variety of health screenings. Students who participated in the sequential self-learning followed by a live skills assessment were surveyed to determine their perceptions of the training. FINDINGS: During the 2014-2015 academic year, 78 students successfully completed health testing training modules. Of these students, 56 (72%) completed an attitudinal survey designed to assess their perceptions. Nearly 93% of respondents perceived improved confidence after completing the training. Regardless of the year in pharmacy school, 88% of respondents believe they would not have been adequately prepared to conduct the health test(s) without this training. SUMMARY: Student perception and acceptance of health testing training were positive. Using sequential training modules to teach and reinforce the skills necessary for performing health tests can improve student ability and confidence. Consequently, students have the opportunity to impact the health of the community while becoming practice ready in the area of health testing.
