BackgroundEvaluation of sensitive myocardial mechanics with speckle tracking echocardiography (STE) across the lifespan may reveal early indicators of cardiovascular disease (CVD) risk. Epicardial adipose tissue (EAT) and left ventricular (LV) myocardial dyssynchrony; subclinical risk-factors of CVD, are of particular clinical interest. However, the evolution of EAT and LV-dyssynchrony across the lifespan, and their influence on myocardial dysfunction remains unclear. We aimed to establish a profile of the healthy aging-heart using conventional, tissue-Doppler imaging (TDI) and speckle-tracking echocardiography (STE), while also exploring underlying contributions from EAT and LV-dyssynchrony towards LV myocardial mechanics, independent of blood biology.MethodsHealthy males aged 19–94 years were recruited through University-wide advertisements in Victoria and New-South Wales, Australia. Following strict exclusion criteria, basic clinical and comprehensive echocardiographic profiles (conventional, TDI and STE) were established. LV-dyssynchrony was calculated from the maximum-delay of time-to-peak velocity/strain in the four LV-annulus sites (TDI), and six LV-segments (STE longitudinal and circumferential axes). Epicardial fat diameter was obtained from two-dimensional grey-scale images in the parasternal long-axis. Blood biological measures included glycemia, hsCRP, triglycerides, total cholesterol, high-density and low-density lipoprotein levels.ResultsThree groups of 15 were assigned to young (<40 years), middle (40–65 years), and older (>65) aged categories. Five participants were excluded from STE analyses due to inadequate image quality. Decreased longitudinal strain, increased circumferential apical strain and LV twist were age-related. Moreover, independent of blood biology, significant increases were observed across age categories for EAT (young: 2.5 ± 0.9 mm, middle: 3.9 ± 1.0 mm, older 5.7 ± 2.4 mm; p < 0.01), longitudinal STE-dyssynchrony (young: 42 ± 7.7 ms, middle: 58.8 ± 18.9 ms, older 88.6 ± 18.2 ms; p < 0.05), and circumferential-basal STE-dyssynchrony (young: 50.2 ± 20.5 ms, middle: 75.9 ± 20.6 ms, older 97.9 ± 20.2 ms; p < 0.05). These variables collectively explained 37% and 31% (p < 0.01) of longitudinal strain and LV twist, respectively.ConclusionsThis study enabled comprehensive profiling of LV mechanics at different stages of aging using sensitive echocardiographic technology. Novel findings included increased epicardial fat, and both longitudinal and circumferential LV-dyssynchrony across the healthy age groups. These factors may be key underlying contributors to myocardial dysfunction during aging, and their recognition may promote an advanced understanding of early signs of cardiovascular disease.
The needs of community-dwelling older Chinese people in the Xiacheng District are not being fully met and much remains be done to increase community and regional capacity before ageing in place can be promoted as a policy strategy. More generally, nursing and health policies geared to enhance the self-sufficiency of older people residing in their communities must draw upon evidence of assessed needs and client perspectives of their requirements before services can be designed and delivered.
As we approach the seventh month of the latest pandemic to wreak havoc and death across all societies, it beggars belief that many world and national leaders have acted surprised at the speed and destructive efficiency of COVID‐19. Nurses are not surprised by the level of misery and devastation that infectious diseases can cause. We have seen it all before. In every outbreak through history, nurses have responded to the dangers that direct engagement with such crises entails. The inherent risks nurses face in controlling potentially fatal pathogens are compounded by flaccid public policy and incompetent management, resulting in poorly resourced preparedness for the epidemics and pandemics that routinely punctuate our history. That nurses are repeatedly placed in such precarious work environments is an indictment on all involved. Over time, nurses responding to populations in crisis have learned not to rely too heavily on those occupying leadership positions for front‐line resources and protection or even early warnings or open disclosure about contagion risk, case numbers and outcomes. Once the danger has passed, the usual public expressions of gratitude for nurses who put themselves in harm’s way to help victims of these catastrophes seem to fade, amid hasty efforts to consolidate policies, processes and hierarchies back to the same settings that allowed the current crisis to flourish. So far in this pandemic, an unconfirmed number of nurses and other health workers have either died usually as a result of their involvement with infectious patients or become infected themselves. Data collection on this is haphazard at best, with nurse deaths absorbed within the aggregated morbidity data reported on during pandemics. This is despite nurses being the prominent professional workforce providing crucial front‐line interventions to protect public health. It is time nurses involved themselves with the overdue reformation of public health policies, information management and health systems that would seek to return nurses to precarious work environments and trivialize foreseeable risks to us, our communities and patients.
This research, based in China, presents an instructive tale for all countries that need support on the types and amounts of management for nurses working at the clinical interface, and on the consequences of management neglect of relevant policies and procedures.
This study aimed to test the utility of the Long-Term Care Quality-of-Life assessment scale within community home care contexts and to compare the scale against the World Health Organization Quality-of-Life scale in terms of reliability and validity. Both scales were administered concurrently to 109 older adults receiving home care. Analysis revealed the Long-Term Care Quality-of-Life scale to have good test-retest reliability, modest but acceptable internal consistency, and pairwise comparison between the Long-Term Care Quality-of-Life and World Health Organization Quality-of-Life scales' scores suggesting moderate-to-strong correlation of criterion validity and comparability between scales. The results showed that the assessment of individual perceptions of life quality within home care contexts can be monitored and recorded, and that Long-Term Care Quality-of-Life scale monitoring in home and residential care can identify opportunities for quality-of-life support and care continuity, even with transitions between care services and systems. The implications of the present study lie in having access to a validated quality-of-life assessment scale that can be used across care contexts to support evidence-based practice, continuity of care, and acknowledgement of individual circumstances in services and care planning.

Researchers have refined the concept of QoL and developed theoretical models to explain how individual measures, with methodologic rigor and practical applications, can fit within care services' contexts (Henchoz et al., 2017). Borowiak and Kostka (2004) note that policies and programs are increasingly focused on finding ways to improve life quality, rather than just extending the length of life. The increasing likelihood of an older person moving between services to obtain care and support means that reliable tools need to be available for the consistent assessment of their reactions to their surroundings across all care contexts. Stakeholders also have an interest in ensuring that government-funding subsidies are used appropriately; therefore, most national funding systems include regulatory frameworks that assess clinical care quality, and more recently, report on patient experiences of life quality because of where they are and the services they receive. The Long-Term Care QoL (LTC-QoL) scale was developed, tested, and published to provide a life quality assessment suitable for people
The study displays the benefits and challenges of participation in policy and forums that help nurse scholars and practitioners understand the development of nurse education in China.
