Universal prescription
In April 2017 the UK Government unveiled its Cycling and Walking Investment Strategy (CWIS), the first binding legislation ensuring government investment in cycling and walking provision in England. CWIS commits 1.2 billion GBP of spending by 2020/2021, coming from central and local government as well as from local enterprise partnerships.
Special Delivery
Drug molecules, without special intervention, don't apply only where we want them to. Indeed, late last year this fact landed pharmaceutical giant Reckitt Benckiser in trouble with the Australian regulator.
Top of the tree
What do civil servants and monkeys have in common (ignoring a purportedly greater than average interest in bananas)?
Habit (re)forming
Behavioural risk factors such as smoking and excessive alcohol consumption are significant drivers of mortality and morbidity.
Making sense of senescence
Historical research we discussed previously proposed that significant increases in average life expectancy would require the cure of multiple diseases of aging. Without considering the detail of cause-of-death calculations conducted more than two decades ago, it certainly seems implausible even now that we'll cross such a dramatic Rubicon in the near-term.
Cart before horse?
Predicting the exact impact of weight upon mortality has proven to be a tricky business. That obesity is on the rise is universally acknowledged, but in recent years we have seen research studies reach differing conclusions, depending on the populations examined and the measures used.
Definitions of age
When modelling longevity, age is well-known to be a crucial risk factor. However it is also well-known that the life-expectancy upon attaining any specific age will differ between populations.
Label without a cause
To talk informally about a concept, we need only give it a recognisable name. For example, we use the label "medical error" and we all know what is meant - or at least we think we do.
Assumed or presumed?
Mortality modelling and research is often critically dependent upon assumptions, but certainty over whether those assumptions are well-founded may come only with hindsight.
Metastatic immunity
In 2013, cancers represented more than one third of the top-fifteen causes of all-age mortality in the UK, irrespective of gender. Despite intensive efforts, for some cancers survival rates have scarcely improved for decades.
