The Incidence and Outcomes of Acute Kidney Disease in Critically Ill Children.

Background: Acute kidney disease (AKD) includes abnormalities of kidney function present for <90 days. Acute kidney injury (AKI) is defined as a subset of AKD, with onset within seven days. There is scant data on the rates of AKD in children and its association with outcomes.

Brain derived β-interferon is a potential player in Alzheimer's disease pathogenesis and cognitive impairment.

Background: Recent research has postulated that the activation of cGAS-STING-interferon signalling pathways could be implicated in the pathogenesis of Alzheimer's disease (AD). However, the precise types of interferons and related cytokines, both from the brain and periphery, responsible for cognitive impairment in patients with AD remain unclear.

Methods: A total of 131 participants (78 [59.

Glomerular Filtration of Creatinine: Validation of a Novel Index of Muscle Mass Among Older Adults.

Rationale & Objective: Low muscle mass is common among older adults and associated with poor prognosis. Quantifying muscle mass is challenging in routine clinical practice. We hypothesized that glomerular filtration of creatinine (GF) reflects muscle mass, and previously proposed estimated GF (eGF), as a practical index of muscle mass in older adults.

Technology literacy and access to digital resources for remote assessment among adults enrolled in Alzheimer's disease research.

Background: The SARS-CoV-2 pandemic accelerated development of innovative methods for conducting research remotely via digital technologies. However, few studies have examined participant technological literacy skills or access as key social determinants of brain health in aging populations at risk of Alzheimer's disease and other dementias.

Objective: To identify associations of sociodemographic and clinical characteristics, cognitive status and geolocation with digital technology access and skill within dementia research cohorts.
