Involving People With Intellectual Disabilities Within Research Teams: Lessons Learned from an Irish Experience

A growing body of literature has shed light into the process of conducting research with people with intellectual disabilities (ID). However, there is limited research on the feasibility of conducting research projects including various groups of people with ID, their supporters, and researchers. This paper reviews three studies conducted with these three groups of people in light of their feasibility, the knowledge generated, and their impact on individual and social change. This study used a reflective analysis focused on the main findings from the three studies, focus groups with people with ID and supporters who conducted the research, and interviews with people to whom the findings were disseminated. The analysis suggested that a team approach including active supporters and experienced researchers was critical to their feasibility. The studies generated knowledge particularly on the perspectives of people with ID on their rights. As a result of participation in these studies, some changes at the individual and social levels occurred, but these were relatively limited. The implications of this analysis for future research are discussed in the context of the implementation of the United Nations Convention on the Rights of Persons with Disabilities.Marie Curie Action

Afrotheria genome; overestimation of genome size and distinct chromosome GC content revealed by flow karyotyping

AbstractAfrotheria genome size is reported to be over 50% larger than that of human, but we show that this is a gross overestimate. Although genome sequencing in Afrotheria is not complete, extensive homology with human has been revealed by chromosome painting. We provide new data on chromosome size and GC content in four Afrotherian species using flow karyotyping. Genome sizes are 4.13Gb in aardvark, 4.01Gb in African elephant, 3.69Gb in golden mole and 3.31Gb in manatee, whereas published results show a mean of 5.18Gb for Afrotheria. Genome GC content shows a negative correlation with size, indicating that this is due to differences in the amount of AT-rich sequences. Low genome GC content and small variance in chromosome GC content are characteristic of aardvark and elephant and may be associated with the high degree of conserved synteny, suggesting that these are features of the Afrotherian ancestral genome

Clues on syntenic relationship among some species of Oryzomyini and Akodontini Tribes (Rodentia: Sigmodontinae)

Sigmodontinae rodents represent one of the most diverse and complex components of the mammalian fauna of South America. Among them most species belongs to Oryzomyini and Akodontini tribes. The highly specific diversification observed in both tribes is characterized by diploid complements, which vary from 2n=10 to 86. Given this diversity, a consistent hypothesis about the origin and evolution of chromosomes depends on the correct establishment of synteny analyzed in a suitable phylogenetic framework. The chromosome painting technique has been particularly useful for identifying chromosomal synteny. In order to extend our knowledge of the homeological relationships between Akodontini and Oryzomyini species, we analyzed the species Akodon montensis (2n=24) and Thaptomys nigrita (2n=52) both from the tribe Akodontini, with chromosome probes of Hylaeamys megacephalus (2n=54) of the tribe Oryzomyini. The results indicate that at least 12 of the 26 autosomes of H. megacephalus show conserved synteny in A. montensis and 14 in T. nigrita. The karyotype of Akodon montensis, as well as some species of the Akodon cursor species group, results from many chromosomal fusions and therefore the syntenic associations observed probably represent synapomorphies. Our finding of a set of such associations revealed by H. megacephalus chromosome probes (6/21; 3/25; 11/16/17; and, 14/19) provides phylogenetic information for both tribes. An extension of these observations to other members of Akodontini and Oryzomyini tribes should improve our knowledge about chromosome evolution in both these groups.Fil: Suarez, Pablo.

Marsupial chromosome DNA content and genome size assessed from flow karyotypes: invariable low autosomal GC content.

Extensive chromosome homologies revealed by cross-species chromosome painting between marsupials have suggested a high level of genome conservation during evolution. Surprisingly, it has been reported that marsupial genome sizes vary by more than 1.2 Gb between species. We have shown previously that individual chromosome sizes and GC content can be measured in flow karyotypes, and have applied this method to compare four marsupial species. Chromosome sizes and GC content were calculated for the grey short-tailed opossum (2n = 18), tammar wallaby (2n = 16), Tasmanian devil (2n = 14) and fat-tailed dunnart (2n = 14), resulting in genome sizes of 3.41, 3.31, 3.17 and 3.25 Gb, respectively. The findings under the same conditions allow a comparison between the four species, indicating that the genomes of these four species are 1-8% larger than human. We show that marsupial genomes are characterized by a low GC content invariable between autosomes and distinct from the higher GC content of the marsupial × chromosome

“Anybody on this list that you're more worried about?” Qualitative analysis exploring the functions of questions during end of shift handoffs

Background Shift change handoffs are known to be a point of vulnerability in the quality, safety and outcomes of healthcare. Despite numerous efforts to improve handoff reliability, few interventions have produced lasting change. Although the opportunity to ask questions during patient handoff has been required by some regulatory bodies, the function of questions during handoff has been less well explored and understood. Objective To investigate questions and the functions they serve in nursing and medicine handoffs. Research design Qualitative thematic analysis based on audio recordings of nurse-to-nurse, medical resident-to-resident and surgical intern-to-intern handoffs. Subjects Twenty-seven nurse handoff dyads and 18 medical resident and surgical intern handoff dyads at one VA Medical Center. Results Our analysis revealed that the vast majority of questions were asked by the Incoming Providers. Although topics varied widely, the bulk of Incoming Provider questions requested information that would best help them understand individual patient conditions and plan accordingly. Other question types sought consensus on clinical reasoning or framing and alignment between the two professionals. Conclusions Handoffs are a type of socially constructed work. Questions emerge with some frequency in virtually all handoffs but not in a linear or predictable way. Instead, they arise in the moment, as necessary, and without preplanning. A checklist cannot model this process element because it is a static memory aid and questions occur in a relational context that is emergent. Studying the different functions of questions during end of shift handoffs provides insights into the interface between the technical context in which information is transferred and the social context in which meaning is created
