Abstract
AIM The study aimed to identify the potential for aged care placements to deliver benefits for second year nursing students when conducted within a supportive framework with debriefing and critical reflection opportunities. BACKGROUND Given the ageing population and complex care needs of aged care facility residents, exacerbated by the high prevalence of dementia, the healthcare workforce's ability to meet older people's care needs is paramount. Yet research shows that nursing students are disengaged from aged care. METHODS Using a quasi-experimental mixed method design within an action research framework, 40 students were allocated a 3-week supported placement in 2011-2012 at one of the two intervention residential aged care facilities in Tasmania, Australia. Staff formed mentor action research groups in each facility and participated in a pre-placement capacity-building programme. Thirty-nine students were placed across 14 control facilities. Data were collected via meetings with students and pre-post placement questionnaires on placement experiences, attitudes and dementia knowledge. RESULTS The intervention facility placement programme led to mentors and students being well prepared for the placement and to students experiencing enhanced teaching and learning derived from high levels of mentor support and increased autonomy. Students' knowledge, understanding and attitudes around aged care and dementia improved. DISCUSSION Mentors working together within an action research framework can provide a supported residential aged care placement for nursing students that improves students' aged care attitudes and understandings. CONCLUSION AND IMPLICATIONS FOR NURSING AND HEALTH POLICY Provision of quality, supported aged care student placements is vital to prepare a new generation of nurses who will have to deal with the complex chronic healthcare needs associated with an ageing population.

Abstract
Genetic studies indicate that chromosome 7q is likely to contain an autism susceptibility locus (AUTS1). We have followed a positional candidate gene approach to identify the relevant gene and report the analysis of four adjacent genes localised to a 800 kb region in 7q32 that contains an imprinted domain: PEG1/MEST, COPG2, CPA1 and CPA5-a previously uncharacterised member of the carboxypeptidase gene family. Screening these genes for DNA changes and association analysis using intragenic single nucleotide polymorphisms (SNPs) provided no evidence for an etiological role in IMGSAC families. We also searched for imprinting mutations potentially implicated in autism: analysis of both DNA methylation and replication timing indicated a normal imprinting regulation of the PEG1/COPG2 domain in blood lymphocytes of all patients tested. The analysis of these four genes strongly suggests that they do not play a major role in autism aetiology, and delineates our strategy to screen additional candidate genes in the AUTS1 locus.

Abstract
OBJECTIVES To examine racial and state differences in the use of advance directives and surrogate decision-making in a nursing home population. DESIGN A retrospective cohort study. SETTING Nursing homes in the states of California (CA), Massachusetts (MA), New York (NY), and Ohio (OH). PARTICIPANTS Nursing home residents: 130,308 in CA, 59,691 in MA, 112,080 in NY, and 98,954 in OH. MEASUREMENTS Minimum Data Set information concerning resident race and whether or not residents have a living will (LW), a do not resuscitate (DNR) order, or a surrogate decision-maker (SDM). RESULTS The proportion of LWs, DNR orders, and SDMs varied significantly (P < .0001) by racial categories in each state. In general, whites were distinctly different from other racial categories. Whites were significantly more likely to have a LW (odds ratio (OR) = 1.9 (CA), OR = 2.2 (NY), OR = 4.9 (OH)), a DNR order (OR = 2.4 (CA), OR = 2.4 (MA), OR = 3.3 (NY), OR = 3.2 (OH)), and a SDM (OR = 1.1 (CA), OR = 1.2 (NY), OR = 1.6 (OH)) than were nonwhites, after adjusting for potentially confounding factors. Significant state differences (P < .0001) were observed in LWs, DNR orders, and SDMs and were most pronounced in residents of Ohio, who were significantly more likely to have a LW than were residents in other states (OR = 9.3). CONCLUSIONS Various resident characteristics explain some of the racial differences, although whites are still more likely to have a LW, a DNR order, or an SDM independent of various resident characteristics included in the adjusted analyses. This pattern is observed in all states, although the ORs varied by state. Some of these differences may be due to distinct cultural approaches to end-of-life care and lack of knowledge and understanding of advance directives. The distinctly higher rates of LWs among all racial groups in Ohio than in other states suggest that states can potentially increase the use of advance directives through intervention.

Abstract
OBJECTIVE To replicate the 1987 survey, referring to the original 1977 study, regarding opinions about treatment for critically ill neonates. STUDY DESIGN A long-term follow-up survey of American Academy of Pediatrics Massachusetts membership, maintaining the 1987 instrument, was initiated. RESULTS A notable demographic shift in respondents from a majority of male practitioners in 1977 (89.6%), to 73% in 1987, to more equal numbers of men and women in 1997 (55% and 45%, respectively; p < 0.001; 1987 vs 1997) was apparent. Pediatricians' attitude changes over the 20-year period were relatively modest and were statistically associated with active medical intervention. In 1997, 75% of respondents rejected review committees as mediators, a marked change from 1987. Regardless of healthcare maintenance organization affiliations, 95% indicated that restrictive fiscal policies would not affect decision-making. CONCLUSION This study indicates stability and consensus in pediatricians' attitudes toward active intervention for critically ill neonates compared with 1977 and 1987 surveys and reveals several claims to professional autonomy.

Abstract
Previous studies have suggested that the serotonin transporter (5-HTT) gene and the gamma-aminobutyric acid receptor subunit beta3 (GABRB3) gene, or other genes in the 15q11-q13 region, are possibly involved in susceptibility to autism. To test this hypothesis we performed an association study on the collection of families from the International Molecular Genetic Study of Autism (IMGSA) Consortium, using the transmission disequilibrium test. Two polymorphisms in the 5-HTT gene (a functional insertion-deletion polymorphism in the promoter and a variable number tandem repeat in the second intron) were examined in 90 families comprising 174 affected individuals. Furthermore, seven microsatellite markers spanning the 15q11-q13 region were studied in 94 families with 182 affected individuals. No significant evidence of association or linkage was found at any of the markers tested, indicating that the 5-HTT and the GABRB3 genes are unlikely to play a major role in the aetiology of autism in our family data set.

Abstract
This paper addresses a collaborative preceptorship program involving a group of undergraduate nursing students, their registered nurse preceptors employed on the paediatric ward of an acute care hospital, and academic staff from a university school of nursing. The project utilised a fourth generation evaluation model, adapted from action research methods, which comprised a series of parallel focussed group discussions with a registered nurse preceptor group and a student nurse group. During the project, members of the two groups explored the issues around the supervision of students in practice in an acute paediatric context. This resulted in the development of innovative approaches to the supervisory practices utilised by preceptors. It also highlighted the benefits of collaboration between universities and hospital staff in developing preceptorship programs which respond appropriately to the needs of both preceptors and students.

Abstract
OBJECTIVE To investigate linkage of candidate disease susceptibility genes to rheumatoid arthritis (RA) in affected sibling pair families stratified for specific clinical features. METHOD Two hundred RA affected sibling pair families were genotyped for informative microsatellite markers mapping within or less than 3cM from: INF alpha, INF gamma, INF beta, IL1 alpha, IL1 beta, IL1R, IL2, IL6, IL5R, IL8R, BCL2, CD40L, NOS3, NRAMP, alpha 1 anti-trypsin, and alpha 1 anti-chymotrypsin, using fluorescence based automated technology. Linkage was examined by defining allele sharing sibling pairs. This was assessed by maximum likelihood-inheritance by descent methods. RESULTS An increase in allele sharing was seen for IL5R in female sibling pairs (LOD 0.91, p = 0.03), for INF gamma in sibling pairs with an affected male (LOD 0.96, p = 0.03) and most significantly for IL2 in sibling pairs where one or both were persistently seronegative (LOD 1.05, p = 0.02). CONCLUSION Weak evidence of linkage of RA to IL5R, IFN gamma, and IL2 has been detected in clinical subsets of sibling pairs suggesting that RA is a genetically heterogeneous disease.

Abstract
OBJECTIVE To determine if there is any evidence of linkage between the natural resistance associated macrophage protein gene, NRAMP1, and rheumatoid arthritis (RA). METHODS Two dinucleotide markers, D2S1471, a highly polymorphic marker within 160 kb of NRAMP1, and a less polymorphic marker in the promoter region of NRAMP1, have been analyzed in 115 affected sib-pair RA families (35 with 2 parents, 18 with one parent) from the Arthritis and Rheumatism Council (ARC) National Repository and an additional 85 probands from the ARC National Twin Study and 96 controls. Individuals were typed for both markers by fluorescence based semiautomated polymerase chain reaction analysis. RESULTS No evidence of increased allele sharing in affected sib-pairs was obtained using identity by descent (IBD), identity by state, and maximum likelihood score (MLS) analysis for the whole data set. A significant increase in allele sharing was observed with marker D2S1471 (LOD 0.74; p 0.05) in the HLA discordant subgroup using IBD and MLS-IBD. No significant differences in allele frequencies were observed for any markers in the association study. CONCLUSION In a subset of sib-pairs that shared one or zero HLA haplotypes, LOD scores suggestive of linkage were observed. This suggests a role for NRAMP1 polymorphism in a subset of patients who do not possess HLA susceptibility alleles.

Abstract
Our aim was to compare the sensitivity of 4 analytical methods to detect linkage to a known disease susceptibility locus, HLA-DRB1, in 100 rheumatoid arthritis sibling pair families with incomplete parental genotype information. Genotypes for the HLA-DRB1 and HLA-A loci were analyzed using (1) identity-by-descent (IBD), considering inheritance of maternal and paternal alleles separately; (2) maximum likelihood score-IBD (MLS-IBD), which infers missing parental genotypes; (3) identity-by-state (IBS), which does not require parental genotypes; and (4) transmission disequilibrium test (TDT), which uses affected offspring with a heterozygous parent. Due to the small number of informative meoisis for HLA-DRB1, the IBD analysis was not significant for linkage (p = 0.014). HLA-A was more informative (p = 0.0002). The MLS-IBD method for HLA-DRB1 (p = 0.00004) and HLA-A (p < or = 0.00001) was significant. Using IBS both loci gave highly significant evidence of linkage, (p < < 0.00001). The TDT detected HLA-DRB1*0401 as the allele associated with RA; no HLA-A allele was associated. Thus, sib pair families with limited parental genotypes can be used to detect disease susceptibility loci, but when selecting the method of analysis the informativeness of the markers should be taken into account.

Abstract
It has been estimated that a number of non-HLA susceptibility loci exist in rheumatoid arthritis (RA), each making relatively small contributions (lambda s < 2). Previous approaches for whole genome screening are unlikely to be sufficiently sensitive to detect such loci. As the pathology of RA already indicates several molecules that may be of potential importance in disease susceptibility, we propose an alternative approach, targeting candidate genes directly. Highly polymorphic dinucleotide markers within a candidate gene sequence or close to the gene can be used as markers, and the selection of the most appropriate markers is discussed. RA sibling pair families from the Arthritis and Rheumatism Council National Repository (n = 200) are used in linkage analysis studies. The data generated are analyzed using sib pair analysis methods to examine evidence of linkage. The interpretation of such results is also discussed, in particular, minimizing the possibility of type I errors, and the interpretation of negative results.

Abstract
Risks for breast cancer when there is a family history of the disease are usually calculated using data from segregation analyses which favour a single dominant gene with high penetrance. There are, however, at least three loci known to be associated with familial breast cancer (p53, BRCA1, and an as yet unpublished locus) and the frequencies and penetrances of these genes are not likely to be the same. We have attempted to address the problem of which genetic parameters should be used to calculate risks for different patterns of familial breast cancer. Data from 384 nuclear families ascertained through a proband selected for early onset breast cancer were subjected to complex segregation analysis, correcting for ascertainment bias resulting from selection for severe phenotype. Age of onset of breast cancer, incorporated as severity, provides additional information to the segregation model over and above that given by assigning liability classes on the basis of age at observation. The use of this additional parameter in the analysis is described. There is fair agreement between estimates from this sample and previous predictions from consecutive probands and consultands. The differences suggest more than one rare dominant gene for susceptibility to breast cancer, with different penetrances. Although refinements of segregation analysis will help to delineate these different genes, perfect resolution will require identification of the mutant alleles. Methods to estimate genetic parameters under genotype specific mortality need to be developed. Meanwhile, we suggest that high and low estimates of penetrance be used in risk estimation for genetic counselling, and as a guide to candidates for entry into clinical trials of screening and chemoprevention in breast cancer.
