智能健康物联网系统对血脂异常人群治疗性生活方式改变的管理效果

目的本研究旨在探索应用智能健康物联网系统对血脂异常人群进行治疗性生活方式改变(therapeutic lifestyle changes,TLC)管理的可行性和有效性。方法将52例血脂异常者作为干预对象,利用智能健康物联网系统(可穿戴设备、居家监测、智能APP)进行TLC健康管理,干预期为3个月,观察干预对象行为习惯(饮食、运动)与生理指标的变化。结果干预后,干预对象的行为习惯观察变量总获益率为5.5%~49.9%,生理指标观察变量总获益率为-6.9%~63.6%;干预对象的体质量指数、腰围、腰臀比、血压、血清总胆固醇、甘油三酯、空腹血糖均较干预前显著下降(P均<0.05)。结论利用智能健康物联网系统对血脂异常人群进行TLC管理有效、可行。     

Daily wastewater pollutant dynamics with respect to catchment population structure

To relate population structure and activity to wastewater volume and composition, field trials were conducted at the outlets of two urban catchments that have different population structures (residential-only and mixed). Macropollution and metal micropollution were both considered. In the residential-only catchment, a diurnal pattern with a morning peak (at 10:00) and an evening peak (at 20:00, corresponding to dinner) was observed for all seasons. No difference was observed throughout the year; patterns in summer days, in which daily mobility out of the catchments should be reduced, were similar to those observed in other seasons. For both catchments, N-NH₄ (from urine) and chemical oxygen demand (from urine and grey water) correlated with Cu, Zn, Al, Fe and Mn but not with alkaline earth metals. The observed diurnal pattern is associated with work and school mobility and with the general lifestyle of the population. Such an approach is useful to model expected domestic pollution patterns, with respect to lifestyle changes in the future.     

Exploring the Role of Genetic Variability and Lifestyle in Oxidative Stress Response for Healthy Aging and Longevity

Oxidative stress is both the cause and consequence of impaired functional homeostasis characterizing human aging. The worsening efficiency of stress response with age represents a health risk and leads to the onset and accrual of major age-related diseases. In contrast, centenarians seem to have evolved conservative stress response mechanisms, probably derived from a combination of a diet rich in natural antioxidants, an active lifestyle and a favorable genetic background, particularly rich in genetic variants able to counteract the stress overload at the level of both nuclear and mitochondrial DNA. The integration of these factors could allow centenarians to maintain moderate levels of free radicals that exert beneficial signaling and modulator effects on cellular metabolism. Considering the hot debate on the efficacy of antioxidant supplementation in promoting healthy aging, in this review we gathered the existing information regarding genetic variability and lifestyle factors which potentially modulate the stress response at old age. Evidence reported here suggests that the integration of lifestyle factors (moderate physical activity and healthy nutrition) and genetic background could shift the balance in favor of the antioxidant cellular machinery by activating appropriate defense mechanisms in response to exceeding external and internal stress levels, and thus possibly achieving the prospect of living a longer life.

Navigating technology: beyond a critical theory

This paper explores how the new communication technologies have impacted on the 'Graphic Information Design' BA Hons at the University of Westminster and uses a reading of the degree course documents from 1970 to the present day to identify and trace the history of this impact. The paper outlines, in particular, the development of the theoretical component of the course and argues that this component, known as contextual studies, has done little to address the impact of the new technologies and the radical paradigm shift from 'page' to 'screen'. It suggests that contextual studies should develop a more appropriate framework which would address these developments and details the content of one module 'Critical Theory' as a possible site for a more appropriate framework. In conclusion, it suggests that the Internet has greater potential than conventional teaching to deliver a more appropriate contextual studies programme; one which would also address the needs of graphic information design students into the 21st century.

Medium-Scale Anatolian Cities: Conceptual and Physical Routes of Urban Transformation

Banu Tomruk investigates the post-1980s transformation of the built environment of medium-scale Anatolian cities. She examines the subject through a conceptual and physical framework that places as much emphasis on populist rhetoric – ‘identity crisis’, ‘historicisation’, ‘the making of a tourist city’ – as on the built structures themselves and their realisation as standardised apartment blocks and gated communities.

Long-Term Effects of Lifestyle Behavior Change in Coronary Artery Disease: Effects on Recurrent Coronary Events After Percutaneous Coronary Intervention.

This study evaluated the effects of a behaviorally oriented cardiac rehabilitation and secondary prevention program on lifestyle changes and on coronary recurrence rates. Patients recently treated with percutaneous coronary intervention (PCI) were randomized to an intervention with an aggressive focus on lifestyle changes (smoking, diet, exercise, and stress; n = 46) or to a standard-care control group (n = 42). Results showed that the intervention group had significantly larger overall lifestyle changes than the control group after 12, 24, 36, and 60 months. The intervention group had significantly lower rates of all coronary events (acute myocardial infarction, coronary artery bypass graft, PCI, cardiac death; 30.4% vs. 53.7%), and of cardiovascular mortality (2.2% vs. 14.6%). The need for future large-scale and long-term evaluations of lifestyle-oriented secondary prevention interventions of this kind is emphasized.

The role of dietary polyphenols in the moderation of the inflammatory response in early stage colorectal cancer

Current focus in colorectal cancer (CRC) management is on reducing overall mortality by increasing the number of early-stage cancers diagnosed and treated with curative intent. Despite the success of screening programs in down-staging CRC, interval cancer rates are substantial and other strategies are desirable. Sporadic CRC is largely associated with lifestyle factors including diet. Polyphenols are phytochemicals ingested as part of a normal diet, which are abundant in plant foods including fruits/berries and vegetables. These may exert their anti-carcinogenic effects via the modulation of inflammatory pathways. Key signal transduction pathways are fundamental to the association of inflammation and disease progression including those mediated by NF-κB and STAT, PI3K and COX. Our aim was to examine the evidence for the effect of dietary polyphenols intake on tumor and host inflammatory responses to determine if polyphenols may be effective as part of a dietary intervention. There is good epidemiological evidence of a reduction in CRC risk from case-control and cohort studies assessing polyphenol intake. It would be premature to suggest a major public health intervention to promote their consumption; however, dietary change is safe and feasible, emphasizing the need for further investigation of polyphenols and CRC risk.
