A randomized comparison trial was carried out at Queen's Hospital, Burton-on-Trent, to compare patient outcomes on the RIK mattress (KCI) and the Nimbus 3 mattress (Huntleigh Healthcare). One hundred and fifty-eight patients, who were assessed to be at particular risk of development of pressure ulcers using the Waterlow score (85 on RIK mattress, 83 on Nimbus), completed the trial. There were no statistically significant differences in baseline parameters at recruitment or pressure ulcer progress. Lack of difference can be as useful as evidence of superiority. Other factors such as nursing interventions required accessible equipment, and costs are important when making equipment choices. For a significant proportion of patients, a static (RIK) mattress can be as effective as an active (Nimbus 3) mattress for management of pressure ulcers.
Growth and development of six hand-reared red bird of paradise chicks was documented at the New York Zoological Park from March 1988 to May 1989. A total of 16 eggs were laid, of which 10 were fertile. Clutches consisted of two eggs and the female left the next infrequently during incubation. Two chicks left in the nest were apparently victims of parental abuse. Eggs were subsequently removed from the nest after 10-14 days, candled, and if fertile, were artificially incubated. The average incubation period was 16.6 days. Newly hatched chicks were without down and their eyes remained closed until approximately 6 days of age. Hand-reared chicks were maintained in Air Shield Infant Isolettes. The weight of newly hatched chicks was about 8 g, and the weight typically doubled during the first week. Ratios of food intake to body weight were highest between day 4 and 10. Pin feathers were visible on the wings after 4 days, and after 3 weeks, the chicks were fully feathered. Analysis of the diet revealed acceptable levels of iron, but vitamin A and E levels were higher than recommended for poultry chicks. This paper documents the first successful hand-rearing of any species of birds of paradise from hatching to fledging.
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.
