EMU: Why and How It Might Happen

'It might happen or it might not': how patients with multiple sclerosis explain their perception of prognostic risk.

This qualitative study aimed to examine risk perception and seriousness of wheelchair dependence in patients with multiple sclerosis. Perceived absolute risk and perceived seriousness were assessed for 2-year, 10-year and lifetime prognosis of wheelchair dependence using visual analogue scales (VAS). In semi-structured interviews, patients (n = 85) were asked to elucidate these VAS scores. Expl...

Clustering in heavy ion collisions . Why it could happen and how to observe it ?

We argue that Clustering in heavy ion collisions could be the missing element in resolving the so-called HBT puzzle, and briefly discuss the different physical situations where clustering could be present. We then propose a method by which clustering in heavy ion collisions could be detected in a model-independent way

Left ventricular hypertrophy: why does it happen?

Patients with end-stage renal disease (ESRD) have much higher rates of cardiovascular disease than the healthy population. Left ventricular hypertrophy (LVH), in particular, is common in this patient group. The impact of a decline in haemoglobin concentration on left ventricular mass index has been well documented. Partial correction of anaemia with recombinant human erythropoietin (epoetin) tr...

Domestic violence: why does it happen? How can it be stopped?

Recruitment to trials - why is it hard and how might we make it less so?

Background Recruiting participants to trials can be extremely difficult. Estimates of just how difficult vary but around half of trials fail to recruit their original target sample size. Poor recruitment can lead to an underpowered study, which may report clinically relevant effects to be statistically non-significant. A non-significant finding increases the risk that an effective intervention ...
