Assessment of Dietary Intake Using Food Photography and Video Recording in Free-Living Young Adults: A Comparative Study.

Background: Conventional methods of dietary assessment are prone to recall bias and place burden on participants.

Objective: Our aim was to compare the performance of image-based dietary assessment (IBDA), including food photography (FP) and video recording (VR), with the criterion of weighed food records (WFR).

Design: In this comparative study, participants captured meals using FP and VR before and after consumption, over 2 days.

Atypical presentations in the hospitalised older adult testing positive for SARS-CoV-2: a retrospective observational study in Glasgow, Scotland.

Understanding of how SARS-CoV-2 manifests itself in older adults was unknown at the outset of the pandemic. We undertook a retrospective observational analysis of all patients admitted to older people's services with confirmed COVID-19 in one of the largest hospitals in Europe. We detail presenting symptoms, prognostic features and vulnerability to nosocomial spread.

Does vitamin D stop inpatients falling? A randomised controlled trial.

Background: Vitamin D deficiency is common in older people and may increase risk of falls and fracture. Hospital inpatients are at particular risk of falling. Previous studies suggest that vitamin D improves neuromuscular function and reduces falls.

Can doctors predict patients' abbreviated mental test scores.

Objectives: the abbreviated mental test is widely used in the assessment of cognitive impairment in elderly patients. However, many doctors do not administer the full 10 questions, preferring to estimate the patient's score instead. We have studied the accuracy of doctors in predicting patients' abbreviated mental test scores.
