The contribution of staff call light response time to fall and injurious fall rates: an exploratory study in four US hospitals using archived hospital data

BMC Health Services Research, 2012
Background Fall prevention programs for hospitalized patients have had limited success, and the effect of programs on decreasing total falls and fall-related injuries is still inconclusive.

Towards an Accelerometer-Based Elderly Fall Detection System Using Cross-Disciplinary Time Series Features

IEEE Access, 2021
Fall causes trauma or critical injury among the geriatric population which is a second leading accidental cause of post-injury mortality around the world. It is crucial to keep elderly people under supervision by ensuring proper privacy and comfort. Thus

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Fall Recognition System to Determine the Point of No Return in Real-Time

Applied Sciences, 2021
In this study, we collected data on human falls, occurring in four directions while walking or standing, and developed a fall recognition system based on the center of mass (COM).

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Increased Motor Time in the Lower Extremity Is Related to Fall History in Older Women

Applied Sciences
Our aim was to determine whether a temporal deterioration in central or peripheral processing was related to a history of falls in older women and observe the relationship between muscular strength in the lower extremity and information processing speed.

Theory and observations of ice particle evolution in cirrus using Doppler radar: evidence for aggregation [PDF]

, 2006
Vertically pointing Doppler radar has been used to study the evolution of ice particles as they sediment through a cirrus cloud. The measured Doppler fall speeds, together with radar-derived estimates for the altitude of cloud top, are used to estimate a

The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Time since falling and fear of falling among community-dwelling elderly

International Psychogeriatrics, 2007
A fall experienced by an elderly person is of special note because it appears to hold a reciprocal causal association with the fear of falling. This study attempts to determine the temporal relationship between the fear of falling and falling among community-dwelling elderly.Data on falls experienced during the previous three years were obtained from ...
