The application process for nurse anesthesia programs: is there room for improvement?

In summary, we have observed that competition among programs for applicants has been strong in recent years. We believe the answers to preparation of adequate numbers of CRNAs in the future should be based upon cooperation and major recruitment activities within our geographical area. In addition, the results of this study will help us focus on strengths and areas needing improvement in our application process and programs. This is important to attract well-qualified students and maintain our reputation for excellence.

An investigation of the HUMVWA31A locus in British Caucasians.

A number of short tandem repeat (STR) loci are currently being examined for their usefulness as markers of identity; HUMVWA31A is one such locus. We used a high-sieving agarose technique to type 200 British Caucasians for this locus. Comparison of the resultant allele frequencies with other published databases showed that their distributions were similar. Observed heterozygosity was similar to that reported in other population studies but significantly lower than expected. A goodness of fit analysis of observed and expected genotypes was highly significant, suggesting a deviation from Hardy-Weinberg equilibrium, although reports from other populations appeared not to show such differences. The possibility that mistyping had led to an erroneous statistic was investigated by detailed examination of samples within our own laboratory and in two other laboratories, involving verification of the agarose typing by both automated fluorescent detection techniques, and sequencing. Other reported deviations from Hardy-Weinberg equilibrium in STR systems are discussed.

Investigation of the STR locus HUMTH01 using PCR and two electrophoresis formats: UK and Galician Caucasian population surveys and usefulness in paternity investigations.

Two hundred unrelated Caucasians from the UK and 210 from Galicia (NW Spain) have been genotyped for the HUMTH01 locus using polymerase chain reaction (PCR) amplification followed by high sieving agarose electrophoresis (UK samples) and polyacrylamide electrophoresis (Galician samples). Allele and genotype frequencies obtained from both populations were in close agreement to those seen by other workers and chi 2 tests of the two populations showed that both were in Hardy-Weinberg equilibrium. The potential usefulness of HUMTH01 in paternity investigations was analysed by constructing, within each population, false family trios, each with a non-father, in order to estimate the actual exclusion rate. The observed rate of exclusion was in close agreement with the expected rate for both populations. Examination of the mother-child pairs in the false families showed a common allele in every case and no evidence of mutation or non-Mendelian inheritance was observed. The HUMTH01 locus shows an informative polymorphism and the production and analysis of population databases is easily achieved. The use of PCR followed by electrophoresis in either gel format appears to provide a quick and straightforward method for investigating the HUMTH01 locus.

Monoclonal antibodies against IgG allotypes G1m(z), G1m(a), G1m(f), G3m(b1/u) and G3m(g1): their usefulness in HAI and capture ELISA.

Monoclonal antibodies (McAbs) were produced against the IgG allotypes G1m(z), G1m(a), G1m(f), G3m(b1/u) and G3m(g1). Four out of the six McAbs described in this paper showed in the haemagglutination assay cross-reactivity with some or all IgG-coated cell samples. In the haemagglutination inhibition assay, all six McAbs are useful as typing reagent for the above allotypes. In this assay, two of the McAbs show two different specificities, which depend on the Ig-coated cell sample used. Five McAbs are useful for allotyping in a capture ELISA. The results with four of these are promising for the development of a quantitative determination of Gm allotypes.
