Development of a reference standard to assign bacterial versus viral infection etiology using an all-inclusive methodology for comparison of novel diagnostic tool performance.

Background: Diagnostic test evaluation requires a reference standard. We describe an approach for creating a reference standard for acute infection using unrestricted adjudication and apply it to compare biomarker tools.

Methods: Adults and children with suspected acute infection enrolled in three prospective studies at emergency departments and urgent cares were included.

The association between objective measurements of sleep quality and postural control in adults: A systematic review.

We systematically reviewed the association between objective sleep quality and postural control based on objective measurements. We searched the electronic databases PUBMED, CINAHL, SCOPUS and Web of Science for studies assessing the relationship between objective measurements of sleep and postural control or gait performance among adults above age 18. All types of articles until April 2020 were considered.

Why Do They Fall? The Impact of Insomnia on Gait of Older Adults: A Case-Control Study.

Study Objectives: To compare gait and cognitive performance conducted separately as a single- (ST) and simultaneously as a dual-task (DT), ie, when a cognitive task was added, among community-dwelling older adults with and without insomnia.

Methods: Participants included: 39 (28 females) community-dwelling older adults with insomnia, 34 (21 females) controls without insomnia. Subject groups were matched for age, gender, and education.

Exceptionally Long-Lived Individuals (ELLI) Demonstrate Slower Aging Rate Calculated by DNA Methylation Clocks as Possible Modulators for Healthy Longevity.

Exceptionally long-lived individuals (ELLI) who are the focus of many healthy longevity studies around the globe are now being studied in Israel. The Israeli Multi-Ethnic Centenarian Study (IMECS) cohort is utilized here for assessment of various DNA methylation clocks. Thorough phenotypic characterization and whole blood samples were obtained from ELLI, offspring of ELLI, and controls aged 53-87 with no familial exceptional longevity.
