Integrated problem solving environment: the SCIRun computational steering system

Journal ArticleSCIRun is a scientific programming environment that allows the interactive construction, debugging, and steering of large-scale scientific computations. We review related systems and introduce a taxonomy that explores different computational steering solutions, Considering these approaches, we discuss why a tightly integrated problem solving environment, such as SCIRun, simplifies the design and debugging phases of computational science applications and how such an environment aids in the scientific discovery process

Progression and adherence to an individually prescribed and supervised resistance training intervention in older adults recovering in hospital from lower limb fragility fracture

This study evaluated adherence and progression with a 12-week resistance training program amongst a sample of older adults recovering in hospital from lower limb fragility fracture. Forty-nine participants (mean age 84 years) commenced the resistance training program seven days after the injury. The exercise prescription involved training of the hip and knee extensors, hip abductors, and ankle plantar- and dorsi flexors using resistive bands. Exercise sessions were completed tri-weekly for six weeks under supervision by a physiotherapist and tri-weekly for an additional six weeks independently. Adherence was assessed as the proportion of exercise sessions completed of those prescribed and any progression in resistance was documented. Level of adherence was not found to be influenced by age, gender, cognition or strength but was greater amongst those admitted from the community setting and for the first six weeks when supervision was present. Participants were able to obtain similar levels of resistance for the injured side compared to the noninjured side for all exercises excluding hip abduction and those admitted from the community setting achieved higher levels of resistance compared to those admitted from the residential care setting. These findings suggest that an early resistance training program is feasible and well tolerated amongst older adults recovering from lower limb fragility fracture. Further work is necessary to determine how this level of resistance training translates into functional improvements and how to improve adherence levels in clinical rehabilitation settings

Beverage intake and obesity in Australian children

Extent: 11p.BACKGROUND: There have been increases in the obesity and overweight rates in Australian children over the past 25 years and it has been suggested that sugar sweetened beverages (SSB) have played a role in this increase. OBJECTIVE: The objectives of this study were to: (1) examine SSB intakes in the 2007 Australian Children’s Nutrition and Physical Activity Survey (2) relate SSB intake to rates of overweight and obesity, socio-economic status (SES), TV viewing time, and activity levels and (3) compare 2007 SSB intakes with data from the 1995 National Nutrition Survey. DESIGN: A computer assisted 24 h dietary recall in 4,400 children aged 2-16 years was performed. RESULTS: In the 2007 survey 47% of all children reported drinking SSBs with 25% consuming sugar sweetened soft drinks on the day of the survey. The mean consumption of soft drink was 436 g/d/consumer. Activity levels were unrelated to SSB consumption. Television viewing was positively related to soft drink consumption with a difference of 55 g/day from bottom to top tertile of time spent TV viewing (p = 0.015) in children aged 9-16 years. 55% of SSB consumption occurred at home and 10% occurred at school. Lower SES status was associated with a greater prevalence of SSB consumption- 30% for the lowest SES quartile vs 19% in the highest quartile. The proportion of overweight who consumed SSBs (which excludes 100% fruit) was not different from the nonoverweight children although the proportion of SSB consumers in the 6% of children who were obese was significant compared with the non-overweight children (59% vs 47%, p < 0.05). In the 2007 survey 23% of children were overweight (17%) or obese (6%) while in the 1995 survey this figure was 21%. The proportion of children consuming SSBs in 1995 and 2007 for selected age groups were: 2-3 years - 25.8% and 12.8% respectively and 4-7 years - 33.6% and 20.5% respectively (p < 0.001 for both). CONCLUSIONS: This cross-sectional data set provides evidence that SSB consumption for Australian children is still high despite the decrease since 1995 in some age groups. It provides little support to conclude that overweight in children is currently being driven by excessive SSB consumption although it may be factor in some obese children. Conclusions are limited by the cross sectional nature of the study.Peter M. Clifton, Lily Chan, Chelsea L. Moss, Michelle D. Miller and Lynne Cobia

Evaluating the Effectiveness of a Formal Dementia Care Training Program: Abilities Care Experts™

Overview: Abilities Care Experts™ (ACE™) is an educational training program for nursing staff who care for individuals with dementia in skilled nursing facilities (SNF). The objective of the program is to provide the nursing staff with knowledge, and methods to engage residents’ remaining abilities in order to maximize occupational participation using a stage-specific dementia care approach. ACE™ training has yet to be evaluated for effectiveness in a controlled study design. Objectives: This study sought to evaluate the effectiveness of the ACE™ training. Design: The study employed a quantitative, cross-sectional, quasi-experimental design. Participants: A total of 29 CNAs, 13 ACE™ trained and 16 non-ACE™ trained, from two Ensign SNFs. Measurements: Participants completed a survey battery measuring key factors associated with quality of care: 1) knowledge 2) attitudes 3) self-efficacy and 4) job satisfaction. Results: Compared to non-ACE™ trained participants, ACE™ trained participants scored higher on each outcome measure. ACE™ participants demonstrated significantly higher levels of self-perception of dementia knowledge (t (27) =3.44, p=.002), knowledge of dementia care approaches (t (26) =3.57, p=.001), and self-efficacy (t (25) =2.40, p=.024). Conclusion: This study provides initial evidence that ACE™ can improve key factors associated with quality of care
