RESUMO

BACKGROUND AND OBJECTIVE: Physical frailty is associated with increased mortality and hospitalizations in older adults. We describe the prevalence of physical frailty and its prognostic impact in patients with a spectrum of fibrotic interstitial lung disease (ILD). METHODS: Patients with fibrotic ILD at the McMaster University ILD programme were prospectively followed up from November 2015 to March 2020. Baseline data were used to classify patients as non-frail (score = 0), pre-frail (score = 1-2) or frail (score = 3-5) based on modified Fried physical frailty criteria. The association between physical frailty and mortality was assessed using time-to-event models, adjusted for age, sex, lung function and diagnosis using the ILD Gender-Age-Physiology (ILD-GAP) score. RESULTS: We included 463 patients (55% male, mean [SD] age 68 [11] years); 82 (18%) were non-frail, 258 (56%) pre-frail and 123 (26%) frail. The most common ILD diagnoses were idiopathic pulmonary fibrosis (n = 183, 40%) and connective tissue disease-associated-ILD (n = 79, 17%). Mean time since diagnosis was 2.7 ± 4.6 years. There were 56 deaths within the median follow-up of 1.71 (interquartile range [IQR] 1.24, 2.31) years. Both frail and pre-frail individuals had a higher risk of death compared to those categorized as non-frail at baseline (adjusted hazard ratio [aHR] 4.14, 95% CI 1.27-13.5 for pre-frail and aHR 4.41, 95% CI 1.29-15.1 for frail). CONCLUSION: Physical frailty is prevalent in patients with ILD and is independently associated with an increased risk of death. Assessment of physical frailty provides additional prognostic value to recognized risk scores such as the ILD-GAP score, and may present a modifiable target for intervention.

RESUMO

Understanding human movement patterns at local, national and international scales is critical in a range of fields, including transportation, logistics and epidemiology. Data on human movement is increasingly available, and when combined with statistical models, enables predictions of movement patterns across broad regions. Movement characteristics, however, strongly depend on the scale and type of movement captured for a given study. The models that have so far been proposed for human movement are best suited to specific spatial scales and types of movement. Selecting both the scale of data collection, and the appropriate model for the data remains a key challenge in predicting human movements. We used two different data sources on human movement in Australia, at different spatial scales, to train a range of statistical movement models and evaluate their ability to predict movement patterns for each data type and scale. Whilst the five commonly-used movement models we evaluated varied markedly between datasets in their predictive ability, we show that an ensemble modelling approach that combines the predictions of these models consistently outperformed all individual models against hold-out data.

RESUMO

We introduce Tilt Map, a novel interaction technique for intuitively transitioning between 2D and 3D map visualisations in immersive environments. Our focus is visualising data associated with areal features on maps, for example, population density by state. Tilt Map transitions from 2D choropleth maps to 3D prism maps to 2D bar charts to overcome the limitations of each. Our article includes two user studies. The first study compares subjects' task performance interpreting population density data using 2D choropleth maps and 3D prism maps in virtual reality (VR). We observed greater task accuracy with prism maps, but faster response times with choropleth maps. The complementarity of these views inspired our hybrid Tilt Map design. Our second study compares Tilt Map to: a side-by-side arrangement of the various views; and interactive toggling between views. The results indicate benefits for Tilt Map in user preference; and accuracy (versus side-by-side) and time (versus toggle).

RESUMO

Collaborative visual analytics leverages social interaction to support data exploration and sensemaking. These processes are typically imagined as formalised, extended activities, between groups of dedicated experts, requiring expertise with sophisticated data analysis tools. However, there are many professional domains that benefit from support for short 'bursts' of data exploration between a subset of stakeholders with a diverse breadth of knowledge. Such 'casual collaborative' scenarios will require engaging features to draw users' attention, with intuitive, 'walk-up and use' interfaces. This paper presents Uplift, a novel prototype system to support 'casual collaborative visual analytics' for a campus microgrid, co-designed with local stakeholders. An elicitation workshop with key members of the building management team revealed relevant knowledge is distributed among multiple experts in their team, each using bespoke analysis tools. Uplift combines an engaging 3D model on a central tabletop display with intuitive tangible interaction, as well as augmented-reality, mid-air data visualisation, in order to support casual collaborative visual analytics for this complex domain. Evaluations with expert stakeholders from the building management and energy domains were conducted during and following our prototype development and indicate that Uplift is successful as an engaging backdrop for casual collaboration. Experts see high potential in such a system to bring together diverse knowledge holders and reveal complex interactions between structural, operational, and financial aspects of their domain. Such systems have further potential in other domains that require collaborative discussion or demonstration of models, forecasts, or cost-benefit analyses to high-level stakeholders.

RESUMO

Purpose The Access to Literacy Assessment System-Phonological Awareness (ATLAS-PA) was developed for use with children with speech and/or language impairment. The subtests (Rhyming, Blending, and Segmenting) are appropriate for children who are 3-7 years of age. ATLAS-PA is composed entirely of receptive items, incorporates individualized levels of instruction, and is adaptive in nature. Method To establish the construct validity of ATLAS-PA, we collected data from children with typical development (n = 938) and those who have speech and/or language impairment (n = 227). Results Rasch analyses indicated that items fit well together and formed a unidimensional construct of phonological awareness. Differential item functioning was minimal between the two groups of children, and scores on ATLAS-PA were moderately to strongly related to other measures of phonological awareness. Information about item functioning was used to create an adaptive version of ATLAS-PA. Conclusions Findings suggest that ATLAS-PA is a valid measure of phonological awareness that can be used with children with typical development and with speech and/or language impairment. Its adaptive format minimizes testing time and provides opportunities for monitoring progress in preschool and early elementary classrooms.

RESUMO

BACKGROUND: Early changes in acid/base and electrolyte concentrations could provide insights into the development of neuropathology at the onset of stroke. We evaluated associations between acid/base and electrolyte concentrations, and outcomes in permanent middle cerebral artery occlusion (pMCAO) model. METHODS: 18-month-old male and female Sprague-Dawley rats underwent pMCAO. Pre-, post- (7 min after occlusion), and at 72 hr of pMCAO venous blood samples provided pH, carbon dioxide, oxygen, glucose, hematocrit, hemoglobin, and electrolyte values of ionized calcium, potassium, and sodium. Multiple linear regression determined predictors of infarct and edema volumes from these values, Kaplan-Meier curve analyzed morality between males and females at 72 hr, and a Cox regression model was used to determine predictors for mortality. RESULTS: Analysis indicated significant differences in acid/base balance and electrolyte levels in aged rats not dependent on sex between the three time points in the pMCAO model. Changes in pH (from pre- to post and post- to 72 hr) and changes in sodium and ionized calcium (from post- to 72 hr) were predictors of infarct volume and edema volume, respectively. Cox Regression revealed there is a 3.25 times increased risk for mortality based on changes in bicarbonate (pre- to post-MCAO). CONCLUSIONS: These early venous blood changes in acid/base balance and electrolytes can be used to predict stroke outcomes in our rat model of stroke. This study provides potential biomarkers to be examined in the human condition that could provide profound prognostic tools for stroke patients.

RESUMO

PURPOSE: In the United Kingdom, critically ill adolescents are treated in either adult or pediatric intensive care units (AICUs or PICUs). This study explores staff perspectives on where and how best to care for this distinct group. MATERIALS AND METHODS: Semistructured interviews were conducted with 12 members of staff (3 medical, 6 nursing, and 3 allied health professionals) working in 4 ICUs; 2 general hospital AICUs and 2 tertiary centre-based PICUs in England. Interviews were audio-recorded, transcribed, and analyzed using framework analysis. FINDINGS: One overarching theme was identified, reflecting staff understanding of the term "adolescent," and this was linked to 2 further themes, each of which had several subthemes. "Needs of the critically ill adolescent" included medical needs, dignity and privacy, issues around consent, and the impact of intensive care admission. "Implications for staff" included managing parental presence and lack of familiarity, and emotional impact, of dealing with this patient group. Some of these factors are currently better accommodated in adult settings. CONCLUSIONS: Decision-making about the place of care should take into account the individual circumstances of the patient (e.g., nature of their medical condition and previous experiences, maturity, family preference) and not be based only on age at admission. We should work across disciplines to ensure we can discover, and consistently deliver, best practice to meet the needs of critically ill adolescents.

RESUMO

Safety lancets are used to collect capillary blood samples to test if neonates have rare but serious congenital conditions, such as sickle cell disease, cystic fibrosis, congenital hypothyroidism and inherited metabolic diseases. Blood samples are taken from the heel, but the procedure can cause the neonate pain or discomfort, as well as a risk of local trauma to the nerves and blood vessels, bleeding, infection and scarring. This article explores the need for blood sampling in neonates, discusses the procedure and outlines the types of lancets available. It describes the Neoheel Safety Lancet (Smiths Medical), whose features are designed to avoid pain and trauma during the procedure. Three case studies are included to describe its use in clinical practice.

RESUMO

Background: Canadian and international guidelines recommend specialized, multidisciplinary teams for the treatment of patients with idiopathic pulmonary fibrosis (IPF). The objective of this cross-sectional clinical study was to investigate the effect of a care coordinator on IPF patient satisfaction and quality of life. Methods: Forty IPF patients were enrolled from the practices of two physicians (n=20/physician), with either low (LCU) or high-coordinator use (HCU). Patient satisfaction was measured with modified FAMCARE and IPF Care UK Patient Support Program (UK-CARE) surveys. Health related quality of life (HRQoL) was assessed with the living with IPF impacts (L-IPFi) survey. An economic model assessed the impact of the coordinator; staff surveys informed patient management requirements, and costs were derived from published literature. Results: Patient satisfaction was similar between the clinics; a trend (P=0.1) towards increased satisfaction among HCU patients was observed. Patients in the HCU clinic reported increased satisfaction (P<0.05) with their current care compared with care prior to joining the tertiary-care clinic, while LCU patients did not. IPF patient HRQoL did not differ between clinics. The coordinator was estimated to alleviate approximately 30% of a physician's IPF-related work load, and to facilitate the care of more patients per physician. Modelled estimates suggest the coordinator lead to annual cost-savings of $137,212. Conclusions: Reliance upon a coordinator during routine management of IPF patients may improve patient satisfaction, spare physician time and lead to annual cost-savings. Future studies should examine the impact of a coordinator on healthcare resource utilization.

RESUMO

Preclinical studies using rodent models of stroke have had difficulty in translating their results to human patients. One possible factor behind this inability is the lack of studies utilizing aged rodents of both sexes. Previously, this lab showed that leukemia inhibitory factor (LIF) promoted recovery after stroke through antioxidant enzyme upregulation. This study examined whether LIF promotes neuroprotection in aged rats of both sexes. LIF did not reduce tissue damage in aged animals, but LIF-treated female rats showed partial motor skill recovery. The LIF receptor (LIFR) showed membrane localization in young male and aged rats of both sexes after stroke. Although LIF increased neuronal LIFR expression in vitro, it did not increase LIFR in the aged brain. Levels of LIFR protein in brain tissue were significantly downregulated between young males and aged males/females at 72 h after stroke. These results demonstrated that low LIFR expression reduces the neuroprotective efficacy of LIF in aged rodents of both sexes. Furthermore, the ability of LIF to promote motor improvement is dependent upon sex in aged rodents.

RESUMO

Objectives: To describe the case mix, resource use and outcomes for adolescents admitted to intensive care units in the UK. Methods: Analysis of national prospectively collected data for all adolescents aged 12-19 years admitted to UK adult or paediatric intensive care units. Results: There were 37,320 admissions of adolescents during the eight-year study period. Excluding elective surgery, respiratory diagnoses were the most common reason for paediatric intensive care unit (PICU) admission, with trauma and intoxication the most common reasons for adult intensive care unit (AICU) admission. Intensive care unit mortality was 6.0% and 5.7% for those admitted to PICUs and AICUs, respectively. Conclusions: Mortality is similar among adolescents admitted to AICUs and PICUs; however, these rates have not been corrected for severity of acute illness or underlying burden of chronic illness, which may be different between AICUs and PICUs. Services planned for the majority of AICU and PICU patients may not be optimal for critically ill adolescents treated in UK intensive care units, who may need special consideration.

RESUMO

Applied visualization researchers often work closely with domain collaborators to explore new and useful applications of visualization. The early stages of collaborations are typically time consuming for all stakeholders as researchers piece together an understanding of domain challenges from disparate discussions and meetings. A number of recent projects, however, report on the use of creative visualization-opportunities (CVO) workshops to accelerate the early stages of applied work, eliciting a wealth of requirements in a few days of focused work. Yet, there is no established guidance for how to use such workshops effectively. In this paper, we present the results of a 2-year collaboration in which we analyzed the use of 17 workshops in 10 visualization contexts. Its primary contribution is a framework for CVO workshops that: 1) identifies a process model for using workshops; 2) describes a structure of what happens within effective workshops; 3) recommends 25 actionable guidelines for future workshops; and 4) presents an example workshop and workshop methods. The creation of this framework exemplifies the use of critical reflection to learn about visualization in practice from diverse studies and experience.

RESUMO

Critically ill adolescents are usually treated on intensive care units optimised for much older adults or younger children. The way they access and experience health services may be very different to most adolescent service users, and existing quality criteria may not apply to them. The objectives of this pilot study were, firstly, to determine whether adolescents and their families were able to articulate their experiences of their critical care admission and secondly, to identify the factors that are important to them during their intensive care unit (ICU) or high dependency unit (HDU) stay. Participants were 14-17 year olds who had previously had an emergency admission to an adult or paediatric ICU/HDU in one of four UK hospitals (two adult, two paediatric) and their parents. Semi-structured interviews were conducted with eight mother-adolescent dyads and one mother. Interviews were transcribed and analysed using framework analysis. CONCLUSION: The main reported determinant of high-quality care was the quality of interaction with staff. The significance of these interactions and their environment depended on adolescents' awareness of their surroundings, which was often limited in ICU and changed significantly over the course of their illness. Qualitative interview methodology would be difficult to scale up for this group. What is known • Critically ill adolescents are usually treated on intensive care units optimised for older adults or younger children. • The way they access and experience health services may be different to most adolescent patients; existing quality criteria may not apply. What is new • Reported determinants of high-quality care were age-appropriateness of the environment, respectfulness and friendliness of staff, communication and inclusion in healthcare decisions. • The significance of these depended on adolescents' awareness of their surroundings, which was often limited and changed over the course of their illness.

RESUMO

Constraint programming allows difficult combinatorial problems to be modelled declaratively and solved automatically. Advances in solver technologies over recent years have allowed the successful use of constraint programming in many application areas. However, when a particular solver's search for a solution takes too long, the complexity of the constraint program execution hinders the programmer's ability to profile that search and understand how it relates to their model. Therefore, effective tools to support such profiling and allow users of constraint programming technologies to refine their model or experiment with different search parameters are essential. This paper details the first user-centred design process for visual profiling tools in this domain. We report on: our insights and opportunities identified through an on-line questionnaire and a creativity workshop with domain experts carried out to elicit requirements for analytical and visual profiling techniques; our designs and functional prototypes realising such techniques; and case studies demonstrating how these techniques shed light on the behaviour of the solvers in practice.

RESUMO

Showing flows of people and resources between multiple geographic locations is a challenging visualisation problem. We conducted two quantitative user studies to evaluate different visual representations for such dense many-to-many flows. In our first study we compared a bundled node-link flow map representation and OD Maps [37] with a new visualisation we call MapTrix. Like OD Maps, MapTrix overcomes the clutter associated with a traditional flow map while providing geographic embedding that is missing in standard OD matrix representations. We found that OD Maps and MapTrix had similar performance while bundled node-link flow map representations did not scale at all well. Our second study compared participant performance with OD Maps and MapTrix on larger data sets. Again performance was remarkably similar.

RESUMO

This 24-week-long pilot investigation of 30 men and women with a BMI > 27 kg/m(2) aimed to determine whether virtual gastric band (VGB) hypnotherapy has an effect on weight loss in overweight adults, compared to relaxation hypnotherapy and a self-directed diet. Levels of weight loss and gain ranged from -17 kg to +4.7 kg in the VGB hypnotherapy group and -9.3 kg to +7.8 kg in the relaxation group. There was no significant difference between VGB hypnotherapy as a main effect on weight loss, (X(2) = 0.67, p = .41, df = 1) and there was no evidence of differential weight loss over time, (X(2) = 4.2, p = .64, df = 6). Therefore, the authors conclude that there was no significant difference between VGB hypnotherapy and the relaxation hypnotherapy.

RESUMO

Comparing multiple variables to select those that effectively characterize complex entities is important in a wide variety of domains - geodemographics for example. Identifying variables that correlate is a common practice to remove redundancy, but correlation varies across space, with scale and over time, and the frequently used global statistics hide potentially important differentiating local variation. For more comprehensive and robust insights into multivariate relations, these local correlations need to be assessed through various means of defining locality. We explore the geography of this issue, and use novel interactive visualization to identify interdependencies in multivariate data sets to support geographically informed multivariate analysis. We offer terminology for considering scale and locality, visual techniques for establishing the effects of scale on correlation and a theoretical framework through which variation in geographic correlation with scale and locality are addressed explicitly. Prototype software demonstrates how these contributions act together. These techniques enable multiple variables and their geographic characteristics to be considered concurrently as we extend visual parameter space analysis (vPSA) to the spatial domain. We find variable correlations to be sensitive to scale and geography to varying degrees in the context of energy-based geodemographics. This sensitivity depends upon the calculation of locality as well as the geographical and statistical structure of the variable.

RESUMO

We present an efficient technique for topology-preserving map deformation and apply it to the visualization of dissimilarity data in a geographic context. Map deformation techniques such as value-by-area cartograms are well studied. However, using deformation to highlight (dis)similarity between locations on a map in terms of their underlying data attributes is novel. We also identify an alternative way to represent dissimilarities on a map through the use of visual overlays. These overlays are complementary to deformation techniques and enable us to assess the quality of the deformation as well as to explore the design space of blending the two methods. Finally, we demonstrate how these techniques can be useful in several-quite different-applied contexts: travel-time visualization, social demographics research and understanding energy flowing in a wide-area power-grid.

RESUMO

While much of the literature on caregiver burden has focused on caregiving for people living with Alzheimer's disease (AD) there is little information on the experience of caring for a loved one living with amnestic Mild Cognitive Impairment (aMCI), the group most likely to convert to AD. A hermeneutic phenomenological approach was used to understand the organizing principles that give experiences of being form and meaning in the lifeworld. Study findings highlight the precarious nature of caregiver role acquisition and the heterogeneity that is present among informal care providers. Specifically, the findings suggest that the wearing of multiple situational masks is required by the carer to cope with accumulated progressive losses suffered as they continually adjust to their new and evolving carer identity. Support groups specific to the carers of those living with aMCI are needed in an effort to remove these masks and to validate this unique caregiving experience.

RESUMO

BACKGROUND: The annual Scientific Meeting of the Canadian Association on Gerontology was held on October 24 and 25, 2008 in London, Ontario. Prior to the annual meeting, mobility and cognition experts met on October 23, 2008 to engage in a pre-conference workshop. METHODS: Discussions during the workshop addressed novel areas of research and knowledge and research gaps pertaining to the interaction between mobility and cognition in seniors. RESULTS: Workshop presenters moved from the neuromuscular, biomechanics, and neurology of gait impairments, and falls through the role of cognition and mood on mobility regulation to the whole person in the environment. Research gaps were identified. CONCLUSIONS: Despite a consensus that mobility and cognition are increasingly correlated as people age, several gaps in our understanding of mechanisms and how to assess the interaction were recognized. The gaps originally identified in 2008 are still pertinent today. Common and standardized assessments for "mobility and cognition" are still not in place in current practice. Interventions that target mobility and cognitive decline as a single entity are still lacking.
