How Flexible Should Bus Service Be? Frequent Networks As a Tool For Permanent Change

Buses are often hailed for their "flexibility" as a transport mode, compared to rail-based technologies. Many cities, though, need certainty about where high-quality services will be in the long term, so that they can guide both land use and road design in harmony with them. Bus Rapid Transit is an obvious example of "bus service made permanent." The infrastructure of BRT represents a fixed government investment in service in a certain place, which in turn provides the certainty that other city actors need as they decide how to grow the city, and whether they can rely on the permanence of the service as they do so. This paper asks: Can we seek similar permanence for frequent local-stop bus lines? A generation of North American land use planners and urbanists has decided that when it comes to local-stop services, trams matter and buses do not. But people make location decisions based on the mobility offered by public transport, so there is at least theoretical reason to believe that we would get better long-term patronage (and urbanist) outcomes if we fixed our best local bus services far in advance. The paper reviews current practice in “Frequent Network” strategies and branding to this end.Institute of Transport and Logistics Studies. Faculty of Economics and Business. The University of Sydne

Assessing physical activity and function in patients with chronic kidney disease: a narrative review

Physical activity potentially improves health outcomes in patients with chronic kidney disease (CKD) and recipients of kidney transplants. Although studies have demonstrated the beneficial effects of physical activity and exercise for primary and secondary prevention of non-communicable diseases, evidence for kidney patients is limited. To enlarge this evidence, valid assessment of physical activity and exercise is essential. Furthermore, CKD is associated with a decline in physical function, which may result in severe disabilities and dependencies. Assessment of physical function may help clinicians to monitor disease progression and frailty in patients receiving dialysis. The attention on physical function and physical activity has grown and new devices have been developed and (commercially) launched on the market. Therefore the aims of this review were to summarize different measures of physical function and physical activity, provide an update on measurement instruments and discuss options for easy-to-use measurement instruments for day-to-day use by CKD patients. This review demonstrates that large variation exists in the different strategies to assess physical function and activity in clinical practice and research settings. To choose the best available method, accuracy, content, preferable outcome, necessary expertise, resources and time are important issues to consider.Clinical epidemiolog

Exhaled breath reflects prolonged exercise and statin use during a field campaign

Volatile organic compounds (VOCs) in exhaled breath provide insights into various metabolic processes and can be used to monitor physiological response to exercise and medication. We integrated and validated in situ a sampling and analysis protocol using proton transfer reaction time-of-flight mass spectrometry (PTR-ToF-MS) for exhaled breath research. The approach was demonstrated on a participant cohort comprising users of the cholesterol-lowering drug statins and non-statin users during a field campaign of three days of prolonged and repeated exercise, with no restrictions on food or drink consumption. The effect of prolonged exercise was reflected in the exhaled breath of participants, and relevant VOCs were identified. Most of the VOCs, such as acetone, showed an increase in concentration after the first day of walking and subsequent decrease towards baseline levels prior to walking on the second day. A cluster of short-chain fatty acids including acetic acid, butanoic acid, and propionic acid were identified in exhaled breath as potential indicators of gut microbiota activity relating to exercise and drug use. We have provided novel information regarding the use of breathomics for non-invasive monitoring of changes in human metabolism and especially for the gut microbiome activity in relation to exercise and the use of medication, such as statin
