Physiotherapist-led home-based physical activity program versus community group exercise for middle-aged adults: Quasi-experimental comparison

引用

Open Journal of Preventive Medicine 2013年第2期3卷 229-237页

作者： Nicole Freene gordon waddington Wendy Chesworth Rachel Davey Tom Cochrane Centre for Research & Action in Public Health Faculty of Health University of Canberra Bruce Australia Faculty of Health University of Canberra Bruce Australia Physiotherapy Faculty of Health University of Canberra Bruce Australia

Objectives: Program method, program deliverer and participant preference may be important factors in increasing physical activity adherence and program effectiveness. To investigate this, we compared two physical activity interventions in middle-aged adults. Methods: Using a pragmatic quasi-experimental design, sedentary community dwelling 50 - 65 year olds (n = 2105) were recruited to a non-randomized 6-month community group exercise program (n = 93) or a physiotherapist-led home-based physical activity program (n = 65). The primary outcome was physical activity adherence derived from exercise diaries. Secondary outcomes included the Active Australia Survey, aerobic capacity (step- test), quality of life (SF-12v2), blood pressure, waist circumference, waist-to-hip ratio (WHR) and body mass index. Results: Home-based participants were more likely to be younger, working full-time and not in a relationship (p Thirty-three percent of the group participants attended ≥ 70% of group exercise sessions. Ninety percent of home-based participants received ≥ 4 of the planned 6 telephone support calls. Intention-to-treat analysis found adherence to the physical activity sessions prescribed was the same for both interventions (26% ± 28% vs. 28% ± 35%). Both interventions significantly increased the number of participants achieving self-reported “sufficient” physical activity (p ≤ 0.001) and significantly decreased waist circumference (p < 0.001) and WHR (p 0.05). Conclusion: The physiotherapist- led home-based physical activity program, requiring few resources, appears to have increased the adoption of physical activity and adherence to physical activity program requirements for sedentary middle-aged adults. The home-based program, providing equivalent health benefits to the group exercise program, may be particularly suitable for those not interested in or unable to attend a group exercise program.

Asymmetric variability between maximum and minimum temperatures in Northeastern Tibetan Plateau:Evidence from tree rings

引用

Science China Earth Sciences 2008年第1期51卷 41-55页

作者： Jacoby gordon Tree-Ring Laboratory Lamont-Doherty Earth Observatory Columbia University NY 10964 USA

Ecological systems in the headwaters of the Yellow River, characterized by hash natural environmental conditions, are very vulnerable to climatic change. In the most recent decades, this area greatly attracted the public's attention for its more and more deteriorating environmental conditions. Based on tree-ring samples from the Xiqing Mountain and A'nyêmagên Mountains at the headwaters of the Yellow River in the Northeastern Tibetan Plateau, we reconstructed the minimum temperatures in the winter half year over the last 425 years and the maximum temperatures in the summer half year over the past 700 years in this region. The variation of minimum temperature in the winter half year during the time span of 1578―1940 was a relatively stable trend, which was followed by an abrupt warming trend since 1941. However, there is no significant warming trend for the maximum temperature in the summer half year over the 20th century. The asymmetric variation patterns between the minimum and maximum temperatures were observed in this study over the past 425 years. During the past 425 years, there are similar variation patterns between the minimum and maximum temperatures; however, the minimum temperatures vary about 25 years earlier compared to the maximum temperatures. If such a trend of variation patterns between the minimum and maximum temperatures over the past 425 years continues in the future 30 years, the maximum temperature in this region will increase significantly.

Unlearning Descartes:Sentient AI is a Political Problem

The emergence of Large Language Models(LLMs)has renewed debate about whether Artificial Intelligence(AI)can be conscious or *** paper identifies two approaches to the topic and argues:(1)A“Cartesian”approach treats consciousness,sentience,and personhood as very similar terms,and treats language use as evidence that an entity is *** approach,which has been dominant in AI research,is primarily interested in what consciousness is,and whether an entity possesses it.(2)An alternative“Hobbesian”approach treats consciousness as a sociopolitical issue and is concerned with what the implications are for labeling something sentient or *** both enables a political disambiguation of language,consciousness,and personhood and allows regulation to proceed in the face of intractable problems in deciding if something“really is”sentient.(3)AI systems should not be treated as conscious,for at least two reasons:(a)treating the system as an origin point tends to mask competing interests in creating it,at the expense of the most vulnerable people involved;and(b)it will tend to hinder efforts at holding someone accountable for the behavior of the systems.A major objective of this paper is accordingly to encourage a shift in *** place of the Cartesian question-is AI sentient?-I propose that we confront the more Hobbesian one:Does it make sense to regulate developments in which AI systems behave as if they were sentient?

Disruption of bone and skeletal muscle in severe burns

引用

Bone Research 2015年第1期3卷 6-10页

作者： gordon L Klein Department of Orthopaedic Surgery and Rehabilitation University of Texas Medical Branch and Shriners Hospitals for Children

Severe burn injury triggers the body＇s nonspecific adaptive responses to acute insult, including the systemic inflammatory and stress responses, as well as the sympathetic response to immobilization. These responses trigger inflammatory bone resorption followed by glucocorticoid-induced apoptosis of osteoblasts and probably osteocytes. Because these patients are catabolic, they suffer concomitant muscle wasting and negative nitrogen balance. The use of anabolic agents such as recombinant human growth hormone and oxandrolone results in improved bone mineral content and muscle strength after approximately I year. Use of bisphosphonates within the first 10 days of a severe burn completely blocks the resorptive bone loss and has the added advantage of appearing to preserve muscle protein from excessive breakdown. The mechanism for the protective effect on muscle is not currently known. However, if the effect of bisphosphonates on muscle can be confirmed, it raises the possibility that bone communicates with muscle.
