Establishment and clinical impacts of decision-support system for older patients with aortic valve stenosis: A retrospective observational study.

Objectives: Treatment decisions for severe aortic stenosis (AS) are complex, since there are two active and comparable options: transcatheter aortic valve implantation and surgical aortic valve replacement. The disease predominantly affects older individuals, who are frequently comorbid with from cognitive impairment. This study aimed to establish a screening-triggered system to assess the decision-making capacity of patients with AS, support their decision-making, and facilitate referrals to specialists when necessary.

Can the clinical sign "head-turning sign" and simple questions in "Neucop-Q" predict amyloid β pathology?

Background: To establish simple screening tests to suspect Alzheimer's disease (AD) pathology, the clinical sign "head-turning sign" (HTS), which is a patient's behavior of turning their head towards their partner to seek assistance with questions posed by the examiner during the interview, and the simple screening questionnaire for dementia named "Neucop-Q" were validated in participants diagnosed with amyloid and tau positron emission tomography (PET).

Methods: We enrolled 155 patients: 47 cognitive normal, 36 with mild cognitive impairment, 64 with dementia, and 8 with psychiatric disorders. All participants underwent Neucop-Q [three questions: Consciousness/self-awareness of cognitive disabilities (C) normal/impaired (nor/imp), Pleasure/pastime (P) nor/imp, and News/knowledge on current topics (N) nor/imp] and amyloid/tau PET.
