Falls affect more than 29 million American adults ages ≥65 years annually. Many older adults experience recurrent falls requiring medical attention. These recurrent falls may be prevented through screening and intervention. In 2014 to 2015, records for 199 older adult patients admitted from a major urban teaching hospital’s emergency department were queried. Open-ended variables from clinicians’ notes were coded to supplement existing closed-ended variables. Of the 199 patients, 52 (26.1%) experienced one or more recurrent falls within 365 days after their initial fall. Half (50.0%) of all recurrent falls occurred within the first 90 days following discharge. A large proportion of recurrent falls among older adults appear to occur within a few months and are statistically related to identifiable risk factors. Prevention and intervention strategies, delivered either during treatment for an initial fall or upon discharge from an inpatient admission, may reduce the incidence of recurrent falls among this population.
Minute amounts of white or brown adipose tissue can be localized in situ within seconds by covering the organ surfaces with an alkaline solution of dithizon (diphenylthiocarbazone) in alcohol and water. The adipose tissues stain deep green, while the other organs remain unstained, or appear in various shades of pink and red. This technique has been successfully applied to various groups of vertebrates (mammals, birds, reptiles, amphibians and fishes), and it works in fresh, in deep frozen and in formalin-fixed specimens. It fails after tissue fixation in mercuric chloride-containing fluids. In vitro studies show that the staining reaction is due to ( 1 ) a preferential solubility of small amounts of dithizon in adipose tissue lipids, and (2) the development of a green color, which appears when dithizon dissolves in lipids or organic solvents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
