Bispecific antibody targeting of lipid nanoparticles.

Lipid nanoparticles (LNP) are the most clinically advanced non-viral gene delivery system. While progress has been made for enhancing delivery, cell specific targeting remains a challenge. Targeting moieties such as antibodies can be chemically-conjugated to LNPs however, this approach is complex and has challenges for scaling up.

Calcineurin/NFAT inhibitors maintain cognition in a preclinical prevention study in an aging canine model of Alzheimer disease.

Brain signaling of calcineurin (CN) and nuclear factor of activated T-cells (NFAT) transcription factor increases in Alzheimer disease (AD) and is associated with synaptic loss, neurodegeneration, neuroinflammation, amyloid-β (Aβ) production, and cognitive decline. CN/NFAT inhibitors ameliorate these neuropathologies in mouse models of AD. Further, chronic use of tacrolimus in transplant patients reduces risk of AD.

New insights into healthy ageing, inflammageing and frailty using metabolomics.

Human ageing is a normal process and does not necessarily result in the development of frailty. A mix of genetic, environmental, dietary, and lifestyle factors can have an impact on ageing, and whether an individual develops frailty. Frailty is defined as the loss of physiological reserve both at the physical and cellular levels, where systemic processes such as oxidative stress and inflammation contribute to physical decline.

Adverse Childhood Experiences (ACEs) in Unhoused Children Increase Odds of Psychiatric Illness, Physical Illness, and Psychiatric Admission.

Unhoused children and adolescents have high rates of adverse childhood experiences (ACEs). The objective of this study was to characterize a large cohort of unhoused children and investigate rates of psychiatric diagnoses, medical diagnoses, and utilization of emergency department (ED) resources depending on the presence of additional documented ACEs. A retrospective cohort of all unhoused children who presented to the ED of a large Midwestern health system from January 2014 to July 2019 were included.
