Implementation of a free-format request profile in a system for retrieving references to scientific publications.

A process is described whereby a set of instructions in free format can be used to control a search of a data file in an efficient manner. The implications of the effectiveness of this process are considered in relation to a system for the storage and retrieval of references to published works in a typical scientific research establishment. Details of this system have been described earlier.

An effective and reliable computerised system for storage and retrieval of references to scientific publications.

A suite of programs has been implemented to facilitate the storage and retrieval of references to published works in a typical scientific research establishment. The retrieval process is governed by searches for specified combinations of keywords, author names, individual references, and lengths of time that references have been held on file. The system currently caters for approximately 1290 journals together with abstracts, reports, supplements, symposia, proceedings and books. Five years experience has proved the system to be reliable and effective, and it requires only 1.5 technician-days per week to operate it and to input about 25 000 articles annually. This system fulfills a requirement felt by many specialised institutions in providing localised control over quantities of information which are too large to be processed manually.

Thyroxine screening values in premature infants.

OBJECTIVES: Premature infants often have low thyroxine levels when compared to fullterm infants. We sought to determine gestational age specific normal ranges for thyroxine screening results for premature infants in neonatal intensive care units. METHODS: Thyroid screening results for infants less than 38 weeks gestation admitted to two NICUs were examined. For each sample the thyroxine Z-score was computed using parameters from fullterm infants. The mean thyroxine Z-score was calculated for each gestational age for days of life 1, 2, 3-7, 8-14, 15-21, 22-28, and 29-60. RESULTS: There were 1144 specimens obtained from 543 premature infants. The mean thyroxine Z-score was below 0 for almost every gestational age and days-of-life category. The mean thyroxine Z-score increased with gestational age, but did not rise with increasing postpartum age. CONCLUSION: The data show that normal thyroxine Z-scores for premature infants are lower than for fullterm infants and remain low at least as long as the infants remain ill.
