Improving Medical and Nurse Practitioner Student Confidence and Clinical Skill in Advance Care Plan Development: A Multidisciplinary Mentorship Model.

BACKGROUND: Advance care planning (ACP) is an integral aspect of patient-centered care, however medical (MD) and Adult-Gerontology Acute Care Nurse Practitioner (AGACNP) students receive minimal education on how to facilitate ACP discussions and ultimately feel uncomfortable having these discussions with patients.1-4 The aim of this project was to increase MD and AGACNP students' perceived ability and confidence in leading ACP conversations through an ACP educational program called the Letter Project Pilot (LPP). METHODS: The LPP consisted of faculty-supervised interactions in the inpatient setting during which students were able to lead ACP discussions with patients by guiding them through an advance directive worksheet that was structured in the format of a letter. Student participants were recruited from the MD and AGACNP programs associated with the academic medical center. Patients were recruited from inpatient medicine and geriatrics units at the academic medical center. At the end of the 3-month pilot, a voluntary, anonymous REDCap survey was used to evaluate 2 primary outcomes of interest:1) the association of the LPP pilot on perceived ACP skills, and 2) the perceived impact of the LPP pilot on ACP in future practice. RESULTS: Students perceived that their experiences positively enhanced their current ACP skills and their ability to have ACP conversations in their future practice. CONCLUSION: The results support that the LPP is a scalable, cost-effective project that increases students' perceived ability and confidence in leading ACP conversations.

Adverse Vascular Risk Relates to Cerebrospinal Fluid Biomarker Evidence of Axonal Injury in the Presence of Alzheimer's Disease Pathology.

BACKGROUND: Vascular risk factors promote cerebral small vessel disease and neuropathological changes, particularly in white matter where large-caliber axons are located. How Alzheimer's disease pathology influences the brain's vulnerability in this regard is not well understood. OBJECTIVE: Systemic vascular risk was assessed in relation to cerebrospinal fluid concentrations of neurofilament light, a biomarker of large-caliber axonal injury, evaluating for interactions by clinical and protein markers of Alzheimer's disease. METHODS: Among Alzheimer's Disease Neuroimaging Initiative participants with normal cognition (n = 117), mild cognitive impairment (n = 190), and Alzheimer's disease (n = 95), linear regression related vascular risk (as measured by the modified Framingham Stroke Risk Profile) to neurofilament light, adjusting for age, sex, education, and cognitive diagnosis. Interactions were assessed by cognitive diagnosis, and by cerebrospinal fluid markers of Aß42, hyperphosphorylated tau, and total tau. RESULTS: Vascular risk and neurofilament light were not related in the main effect model (p = 0.08). However, interactions emerged for total tau (p = 0.01) and hyperphosphorylated tau (p = 0.002) reflecting vascular risk becoming more associated with cerebrospinal fluid neurofilament light in the context of greater concentrations of tau biomarkers. An interaction also emerged for the Alzheimer's disease biomarker profiles (p = 0.046) where in comparison to the referent 'normal' biomarker group, individuals with abnormal levels of both Aß42 and total tau showed stronger associations between vascular risk and neurofilament light. CONCLUSION: Older adults may be more vulnerable to axonal injury in response to higher vascular risk burdens in the context of concomitant Alzheimer's disease pathology.

Tau positron emission tomographic imaging in aging and early Alzheimer disease.

OBJECTIVE: Detection of focal brain tau deposition during life could greatly facilitate accurate diagnosis of Alzheimer disease (AD), staging and monitoring of disease progression, and development of disease-modifying therapies. METHODS: We acquired tau positron emission tomography (PET) using (18)F T807 (AV1451), and amyloid-ß PET using (11)C Pittsburgh compound B (PiB) in older clinically normal individuals, and symptomatic patients with mild cognitive impairment or mild AD dementia. RESULTS: We found abnormally high cortical (18)F T807 binding in patients with mild cognitive impairment and AD dementia compared to clinically normal controls. Consistent with the neuropathology literature, the presence of elevated neocortical (18)F T807 binding particularly in the inferior temporal gyrus was associated with clinical impairment. The association of cognitive impairment was stronger with inferior temporal (18)F T807 than with mean cortical (11)C PIB. Regional (18)F T807 was correlated with mean cortical (11)C PiB among both impaired and control subjects. INTERPRETATION: These findings suggest that (18)F T807 PET could have value as a biomarker that reflects both the progression of AD tauopathy and the emergence of clinical impairment.
