    Published electronically October 2020BACKGROUND AND OBJECTIVES: despite growing support for the clinical application of frailty, including regular frailty screening for older adults, little is known about how older adults perceive frailty screening. The purpose of this study was to examine older adults' perspectives on frailty screening to inform knowledge translation and service improvements for older adults with frailty. RESEARCH DESIGN: interpretive descriptive qualitative design. PARTICIPANTS: a total of 39 non-frail (18%), pre-frail (33%) and frail or very frail (49%) South Australian older adults aged 62-99 years, sampled from community, assisted living and residential aged care settings. METHODS: seven focus groups were conducted and analysed by two independent investigators using inductive thematic analysis. RESULTS: three themes were identified. First, older adults question the necessity and logic of an objective frailty measure. Second, older adults believe any efforts at frailty screening need to culminate in an action. Third, older adults emphasise that frailty screening needs to be conducted sensitively given negative perceptions of the term frailty and the potential adverse effects of frailty labelling. DISCUSSION AND IMPLICATIONS: previous screening experiences and underlying beliefs about the nature of frailty as inevitable shaped openness to, and acceptance of, frailty screening. Findings correspond with previous research illuminating the lack of public awareness of frailty and the nascent stage of frailty screening implementation. Incorporating consumer perspectives, along with perspectives of other stakeholder groups when considering implementing frailty screening, is likely to impact uptake and optimise suitability-important considerations in person-centred care provision.Mandy M.

    OnlinePublGiven the high prevalence of chronic conditions and multimorbidity in older adults, there is a need to better conceptualize and measure self-care and self-management to promote a person-centered approach. This scoping review aimed to identify and map instruments measuring self-care and self-management of chronic conditions by older adults. We searched six electronic databases, charted data from the studies and tools and reported the results in accordance with the PRISMA-ScR guidelines. A total of 107 articles (103 studies) containing 40 tools were included in the review. There was substantial variation in the tools in terms of their aims and scope, structure, theoretical foundations, how they were developed, and the settings in which they have been used. The quantity of tools demonstrates the importance of assessing self-care and self-management. Consideration of the purpose, scope, and theoretical foundation should guide decisions about tools suitable for use in research and clinical practice.Michael T. Lawless, Matthew Tieu, Raymond J.

    Although somatic mutations in Histone 3.3 (H3.3) are well-studied drivers of oncogenesis, the role of germline mutations remains unreported. We analyze 46 patients bearing de novo germline mutations in histone 3 family 3A (H3F3A) or H3F3B with progressive neurologic dysfunction and congenital anomalies without malignancies. Molecular modeling of all 37 variants demonstrated clear disruptions in interactions with DNA, other histones, and histone chaperone proteins. Patient histone posttranslational modifications (PTMs) analysis revealed notably aberrant local PTM patterns distinct from the somatic lysine mutations that cause global PTM dysregulation. RNA sequencing on patient cells demonstrated up-regulated gene expression related to mitosis and cell division, and cellular assays confirmed an increased proliferative capacity. A zebrafish model showed craniofacial anomalies and a defect in Foxd3-derived glia. These data suggest that the mechanism of germline mutations are distinct from cancer-associated somatic histone mutations but may converge on control of cell proliferation

    Whole-genome sequencing reveals host factors underlying critical COVID-19

    Critical COVID-19 is caused by immune-mediated inflammatory lung injury. Host genetic variation influences the development of illness requiring critical care1 or hospitalization2,3,4 after infection with SARS-CoV-2. The GenOMICC (Genetics of Mortality in Critical Care) study enables the comparison of genomes from individuals who are critically ill with those of population controls to find underlying disease mechanisms. Here we use whole-genome sequencing in 7,491 critically ill individuals compared with 48,400 controls to discover and replicate 23 independent variants that significantly predispose to critical COVID-19. We identify 16 new independent associations, including variants within genes that are involved in interferon signalling (IL10RB and PLSCR1), leucocyte differentiation (BCL11A) and blood-type antigen secretor status (FUT2). Using transcriptome-wide association and colocalization to infer the effect of gene expression on disease severity, we find evidence that implicates multiple genes—including reduced expression of a membrane flippase (ATP11A), and increased expression of a mucin (MUC1)—in critical disease. Mendelian randomization provides evidence in support of causal roles for myeloid cell adhesion molecules (SELE, ICAM5 and CD209) and the coagulation factor F8, all of which are potentially druggable targets. Our results are broadly consistent with a multi-component model of COVID-19 pathophysiology, in which at least two distinct mechanisms can predispose to life-threatening disease: failure to control viral replication; or an enhanced tendency towards pulmonary inflammation and intravascular coagulation. We show that comparison between cases of critical illness and population controls is highly efficient for the detection of therapeutically relevant mechanisms of disease

    Micro-Sized Enterprises, Innovation and Universities: A Welsh Perspective

    No full text
    his study considers the linkage between micro-sized enterprises and other organizations, especially universities, in relation to the innovation process. The focus of the research is on non-start-up enterprises in Wales and how they develop their products. The research methodology adopted is a thematic literature review and the case study approach. The findings demonstrate that there are additional barriers to innovation in terms of legislation and regulation when micro-sized enterprises endeavour to overcome their knowledge gap through collaborating with universities. It is noted that there has been minimal research examining the knowledge gap encountered by micro-sized enterprises and how they attempt to overcome the barriers to collaborating with universities

    Rethinking the Emergence of Relationship Marketing

    No full text
    In this article, the history of relationship marketing (RM) is challenged. Similar to discussions of the marketing concept, the debates surrounding RM are largely ahistorical. This is despite numerous scholars indicating that RM has a far longer history than is currently appreciated. In contrast to received wisdom that RM emerged in the late 1970s, it is demonstrated that RM themes have been present in the marketing literature for longer than is recognized by the contemporary scholars

    Association between Vitamin D Levels and Nonalcoholic Fatty Liver Disease: Potential Confounding Variables

    Get PDF
    Nonalcoholic fatty liver disease (NAFLD), historically considered to be the hepatic component of the metabolic syndrome, is a spectrum of fat-associated liver conditions, in the absence of secondary causes, that may progress to nonalcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. Disease progression is closely associated with body weight or fatness, dyslipidemia, insulin resistance, oxidative stress, and inflammation. Recently, vitamin D deficiency has been linked to the pathogenesis and severity of NAFLD because of vitamin D "pleiotropic" functions, with roles in immune modulation, cell differentiation and proliferation, and regulation of inflammation. Indeed, several studies have reported an association between vitamin D and NAFLD/NASH. However, other studies have failed to find an association. Therefore, we sought to critically review the current evidence on the association between vitamin D deficiency and NAFLD/NASH, and to analyze and discuss some key variables that may interfere with this evaluation, such as host-, environment-, and heritability-related factors regulating vitamin D synthesis and metabolism; definitions of deficient or optimal vitamin D status with respect to skeletal and nonskeletal outcomes including NAFLD/NASH; methods of measuring 25(OH)D; and methods of diagnosing NAFLD as well as quantifying adiposity, the cardinal link between vitamin D deficiency and NAFLD
