The immune system is a key player in the onset and progression of neurodegenerative disorders. While brain resident immune cell-mediated neuroinflammation and peripheral immune cell (eg, T cell) infiltration into the brain have been shown to significantly contribute to Alzheimer's disease (AD) pathology, the nature and extent of immune responses in the brain in the context of AD and related dementias (ADRD) remain unclear. Furthermore, the roles of the peripheral immune system in driving ADRD pathology remain incompletely elucidated.

Design: Secondary analysis of data collected in the PeppeR develOpMental ProjecT (PROMPT) at the University of Florida (Gainesville, FL, USA).
Methods: Forty-three older adults (n = 20 women) were included in the study.
Background: It is unclear whether chronically training close to volitional failure influences motor unit recruitment strategies during fatigue.
Purpose: We compared resistance training to near volitional failure . non-failure on individual motor unit action potential amplitude (MUAP) and surface electromyographic excitation (sEMG) during fatiguing contractions.
: Older adults in residential aged care facilities (RACFs) experience disproportionate levels of poor oral health relative to other groups in the general population, affecting their physical and mental wellbeing. The Oral Health Assessment Tool (OHAT) is a validated and widely used dental assessment tool; however, recent systematic reviews have identified shortcomings with respect to its measurement properties. : The objective of this protocol is to provide a detailed overview of a multidisciplinary qualitative study that aims to (a) co-design and develop a modified OHAT for RACFs and (b) inform the development of an OHAT training package and implementation strategies.
