The act of giving: a pilot and feasibility study of the My Life Story programme designed to foster positive mental health and well-being in adolescents and older adults

Twelve pairs of adolescent students were linked to an older adult in aged care in this pilot study on intergenerational interaction. Triads met weekly for eight weeks with the aim of writing a Life Review Book for the older adult. At the conclusion of the study, participants were interviewed to gain an understanding of their experiences and meaning of the programme. Thematic analysis of the interviews revealed four major themes: breaking down the stereotypes, recognition of heterogeneity, satisfaction from ‘making the effort’ and personal gain through making a contribution. Measures of psychological well-being were also administered pre- and post-delivery of the programme. This revealed that both age groups could and would complete all aspects of the programme. It was concluded from the findings that the intergenerational programme is feasible in the context of adolescent and older adult intergenerational relationships, and a potential influence on well-being for those who take part.

Feasibility of conducting a palliative care randomized controlled trial in children with advanced cancer: assessment of the PediQUEST study

Pediatric palliative care randomized controlled trials (PPC-RCTs) are uncommon.

A study of the feasibility of wool bonded polyurethane for sportswear applications

This study investigates if surface modification, in conjunction with thermal transfer, will improve the adhesion of polyurethane films onto a wool fabric surface for sportswear application. Atmospheric pressure plasma and hydrogen peroxide treatments were used to enhance the surface energy of the wool fabric. Polyurethane polymer films were transferred onto the surface of treated fabrics using a hot press method. The effectiveness of different treatments to improve the adhesion of the film onto the wool surface was tested by washing fastness and the stretch recovery of polyurethane bonded fabrics. The results confirmed improvement on adhesion properties of wool bonded fabrics after different treatments.

An adaptive orientation misalignment calibration method for shoulder movements using inertial sensors : a feasibility study

Qualitative assessment of the progress in physical rehabilitation largely depends on accurate measurement of the range of movements and other kinematic parameters. In clinical practice, wearable inertial sensors have proved to be a potential candidate for such measurements, over the traditional marker based optical systems due to cost and space considerations. The accuracy of wearable sensors have a significant dependence on the initial orientation calibration and the assumption that the sensor will not slip or move with respect to the attached limb. This article introduces a novel calibration algorithm to correct initial orientation misalignment, as well as to track and correct subsequent alignment errors progressively throughout the experiment. The theoretical assertions are validated through controlled experiments with simulated accelerometer and gyroscope measurements.

Accuracy of body size estimation: Role of biopsychosocial variables

This study evaluated factors related to the perceptual disturbances of body image. Using a digital body image computer program, 191 participants (107 women, 82 men) adjusted an image of their body to the perceived actual size at five body regions; chest, waist, hips, thighs and calves. A neutral object (a vase) was also adjusted to partial out the level of perceptual distortion present with a neutral object. Men and women overestimated the size of the neutral object and their body image. Among women, overestimation was primarily predicted by high levels of depression, and media and peer influences to be thinner and increase muscles. Among men, overestimation was predicted by high BMI, media influences to lose weight and increase muscles, and peer influences to increase muscles. These findings suggest that perceptual accuracy of body image is primarily predicted by biopsychosocial influences.

How acceptable is a referral and telephone-based outcall programme for men diagnosed with cancer? A feasibility study

The objective of this study was to determine the feasibility and acceptability of a referral and outcall programme from a telephone-based information and support service, for men newly diagnosed with colorectal or prostate cancer. A block randomized controlled trial was performed involving 100 newly diagnosed colorectal and prostate cancer patients. Patients were referred to the Cancer Information Support Service (CISS) through clinicians at diagnosis. Clinicians were randomized into one of three conditions. Active referral 1: specialist referral with four CISS outcalls: (1) ≤1 week of diagnosis; (2) at 6 weeks; (3) 3 months; and (4) 6 months post diagnosis. Active referral 2: specialist referral with one CISS outcall ≤1 week of diagnosis. Passive referral: specialist recommended patient contacts CISS, but contact at the patient's initiative. Patients completed research questionnaires at study entry (before CISS contact), then 4 and 7 months post diagnosis. Overall, 96% of participants reported a positive experience with the referral process; 87% reported they were not concerned about receiving the calls; and 84% indicated the timing of the calls was helpful. In conclusion, the referral and outcall programme was achievable and acceptable for men newly diagnosed with colorectal or prostate cancer.

Comparative accuracy of magnetic resonance imaging and ultrasonography in confirming clinically diagnosed patellar tendinopathy

Background: Diagnosis of patellar tendinopathy is based primarily on clinical examination; however, it is commonplace to image the patellar tendon for diagnosis confirmation, with the imaging modalities of choice being magnetic resonance imaging (MRI) and ultrasonography (US). The comparative accuracy of these modalities has not been established.

Hypothesis: Magnetic resonance imaging and US have good (>80%) accuracy and show substantial agreement in confirming clinically diagnosed patellar tendinopathy.

Study Design: Cohort study (diagnosis); Level of evidence, 2.

Methods: Magnetic resonance imaging and US (gray scale [GS-US] and color Doppler [CD-US]) features of 30 participants with clinically diagnosed patellar tendinopathy and 33 activity-matched, asymptomatic participants were prospectively compared. Accuracy, sensitivity, specificity, positive and negative predictive values, and the likelihood of positive and negative test results were determined for each technique.

Results: The accuracy of MRI, GS-US, and CD-US was 70%, 83%, and 83%, respectively (P = .04; MRI vs GS-US). The likelihood of positive MRI, GS-US, and CD-US was 3.1, 4.8, and 11.6, respectively. The MRI and GS-US had equivalent specificity (82% vs 82%; P = 1.00); however, the sensitivity of GS-US was greater than MRI (87% vs 57%; P = .01). Sensitivity (70% vs 87%; P = .06) and specificity (94% vs 82%; P = .10) did not differ between CD-US and GS-US.

Conclusions: Ultrasonography was more accurate than MRI in confirming clinically diagnosed patellar tendinopathy. GS-US and CD-US may represent the best combination for confirming clinically diagnosed patellar tendinopathy because GS-US had the greatest sensitivity, while a positive CD-US test result indicated a strong likelihood an individual was symptomatic.

Accuracy of ARGOS locations of pinnipeds at-sea estimated using Fastloc GPS

Background: ARGOS satellite telemetry is one of the most widely used methods to track the movements of free-ranging marine and terrestrial animals and is fundamental to studies of foraging ecology, migratory behavior and habitat-use. ARGOS location estimates do not include complete error estimations, and for many marine organisms, the most commonly acquired locations (Location Class 0, A, B, or Z) are provided with no declared error estimate.
Methodology/Principal Findings: We compared the accuracy of ARGOS locations to those obtained using Fastloc GPS from the same electronic tags on five species of pinnipeds: 9 California sea lions (Zalophus californianus), 4 Galapagos sea lions (Zalophus wollebaeki), 6 Cape fur seals (Arctocephalus pusillus pusillus), 3 Australian fur seals (A. p. doriferus) and 5 northern elephant seals (Mirounga angustirostris). These species encompass a range of marine habitats (highly pelagic vs coastal), diving behaviors (mean dive durations 2–21 min) and range of latitudes (equator to temperate). A total of 7,318 ARGOS positions and 27,046 GPS positions were collected. Of these, 1,105 ARGOS positions were obtained within five minutes of a GPS position and were used for comparison. The 68^th percentile ARGOS location errors as measured in this study were LC-3
0.49 km, LC-2 1.01 km, LC-1 1.20 km, LC-0 4.18 km, LC-A 6.19 km, LC-B 10.28 km.
Conclusions/Significance: The ARGOS errors measured here are greater than those provided by ARGOS, but within the range of other studies. The error was non-normally distributed with each LC highly right-skewed. Locations of species that make short duration dives and spend extended periods on the surface (sea lions and fur seals) had less error than species like elephant seals that spend more time underwater and have shorter surface intervals. Supplemental data (S1) are provided allowing the creation of density distributions that can be used in a variety of filtering algorithms to improve the quality of ARGOS tracking data.

An Arakawa and Gins experimental teaching space - a feasibility study

Many researchers and practitioners currently teaching at Universities use the works of Arakawa and Gins within their courses and some go as far as structuring entire courses on their work. This indcates the value of Arakawa and Gins’ insight which offers many opportunities to intensify the relationship of theory to practice, disciplinary inquiry to knowledge and art to life. Having spent time in each of Arakawa and Gins’ built works, I have experienced and evaluated the benefits of constructing relationships among bodily movement, tactically posed surrounds and the discursive sequences that best constrain them. Based on my experience, I advocate going beyond the study of finished products towards the practice of coordinating history, community, person and body that occurs when inventing and assembling architectural procedures. This paper will outline my efforts over the last eighteen months to produce a feasibility study for building an experimental teaching space at my University (Griffith University, Australia). The experimental teaching space that I am proposing would commission and enact the architectural procedures of Arakawa and Gins in a constantly changing built (in-the-process-of-being-built) environment, where the guided construction of the teaching space is the curriculum. This approach would offer an alternative to the design trend in teaching and learning environments toward technologically driven smart spaces. An experimental space based on “perceptual learning”, “sited awareness” and “daily reserach” would address the disconnection between current research from the life sciences, developmental psychology, rehabilitation science and blended learning—and the enrivonments in which learning occurs. My discussions will address two issues: the link between pedagogical concerns of advanced study with the production of commual space (organism-person-surrounds) and how these goals can be implemented within the institutional planning processes while adhering to new federal funding guidelines, new performance indicatiors, and public tender guidelines. Throughout my paper, I argue that an experimental teaching space would accentuate multidisciplinarity and offer budding teachers, life scientists, sociologists, historians, and artists the enactive tools by which to affect change and provide grounded cultural leadership.

Team clinical supervision in acute hospital wards : a feasibility study

Clinical supervision provides a strategy to mitigate nurses’ workplace stress and enhance retention, but the literature provides little guidance about its implementation beyond mental health nursing. This study explored the feasibility of implementing and evaluating ward-based team clinical supervision for general nurses on two separate wards at one public and one private hospital. Nurses completed the Work Environment Questionnaire pre- (n = 36) and post intervention (n = 27), and focus groups (n = 20) explored their perceptions of supervision. Staff were unfamiliar with clinical supervision, so information sessions were required. The questionnaire may not have been suitable to evaluate this type of intervention. Focus group findings revealed that team supervision improved communication, enhanced working relationships, and empowered nurses to challenge existing practices, which had a positive impact on their perceived stress. This study provides insights to guide implementation and evaluation of clinical supervision in acute settings.

Accuracy of national mortality codes in identifying adjudicated cardiovascular deaths

Objective: This study investigated the sensitivity and specificity of the national mortality codes in identifying cardiovascular disease (CVD) deaths and documents methods of verification.

Methods: A 12-year retrospective case ascertainment of all ICD-coded CVD deaths was performed for deaths between 1990 and 2002 in the Melbourne Collaborative Cohort Study, comprising 41,528 subjects. Categories of non-CVD codes were also examined. Stratified samples of 750 deaths were adjudicated from a total of 2,230 deaths. Expert panels of cardiologists and neurologists adjudicated deaths.

Results: Of the 750 deaths adjudicated, 582 were verified as CVD [392 coronary heart disease (CHD) and 92 stroke] and 168 non-CVD. Estimated sensitivity and specificity of national mortality codes for identifying specific causes of death were: CHD 74.2% (95% CI: 69.8–78.5%) and 97.6% (96.0–99.2%), respectively; myocardial infarction 59.9% (50.9–69.0%) and 94.2% (92.4–96.0%), respectively; haemorrhagic stroke 58.9% (46.0–71.7%) and 99.8% (99.4–100.0%), respectively and; ischaemic stroke 38.7% (20.5–56.9%) and 99.9% (99.6–100.0%), respectively. Misclassification was most common for deaths with primary ICD codes for endocrine-metabolic and genito-urinary diseases.

Conclusions: National mortality coding under-estimated the true proportion of CHD and stroke deaths in the cohort by 13.6% and 50.8%, respectively.

A combined strength and balance exercise program to decrease falls risk in dialysis patients : a feasibility study

People suffering end-stage kidney disease receiving hemodialysis have a greater risk of falling and suffering debilitating injuries. The purpose of this study was to examine the feasibility and impact of a combined strength and balance exercise intervention on falls risk in hemodialysis patients. Twenty-four adults (mean age = 67.8 yrs) from two Australian outpatient hemodialysis clinics completed the intervention. Falls risk was measured using the Physiological Profile Assessment (PPA). There was a significant reduction in the median overall falls risk z-score from 1.67 to .52 (z = -3.11, P<.008; r = .45). Median reaction time improved from .30 to .26 sec (z = -2.86, P<.008; r = .41). A strength and balance intervention to reduce the falls risk for dialysis patients is feasible and may reduce falls risk for at risk patients.
