[Perspectives] Abortion narratives: moving from statistics to stories

The Lancet - Me, 09/05/2018 - 09:00
A Nigerian obstetrician once asked me why I didn't—as he did in his campaigning work—display photographs of haemorrhaging teenage girls, perforated uteri, and prolapsed bowels: the images from the front-line of his daily battle against death from unsafe abortion. In high-income countries with permissive legal regimes and fairly easy access to safe abortion services, people are protected from the bloody consequences of illegal abortion. It has been an easy badge of honour for pro-choice advocates that we draw on research and avoid mirroring the inflammatory language and graphic imagery used by some anti-abortion groups.

New Scientist - Lu, 07/05/2018 - 12:00

[Comment] Contemporary cardiovascular risk prediction

The Lancet - Sa, 05/05/2018 - 00:30
Cardiovascular disease remains an important health problem, accounting for 3·9 million deaths every year in Europe alone.1 To reduce the incidence of cardiovascular disease, risk prediction models are widely used for risk-tailored management, such as antihypertensive and lipid-lowering treatment. More than 350 risk prediction models have been developed for cardiovascular disease in the past decades. These models are mainly based on long-standing cohort data, but only a few models have been validated externally to test their generalisability in present settings.

[Articles] Cardiovascular disease risk prediction equations in 400 000 primary care patients in New Zealand: a derivation and validation study

The Lancet - Sa, 05/05/2018 - 00:30
We constructed a large prospective cohort study representing typical patients in primary care in New Zealand who were recommended for cardiovascular disease risk assessment. Most patients are now at low risk of cardiovascular disease, which explains why the PCEs based mainly on old cohorts substantially overestimate risk. Although the PCEs and many other equations will need to be recalibrated to mitigate overtreatment of the healthy majority, they also need new predictors that include measures of socioeconomic deprivation and multiple ethnicities to identify vulnerable high-risk subpopulations that might otherwise be undertreated.
