Do you pay attention to the haematocrit? In case you’d forgotten, it should lie between 39% and 54%, and in case you thought it’s a waste of time, here is a study to prove otherwise. […]

This meta-analysis of rosiglitazone and cardiovascular events appeared on the NEJM website some weeks ago, and few readers with an interest in diabetes can have failed to read something or other about it, or even the paper itself. I think most people will find it extraordinarily difficult to analyze. […]

Diagnostic studies are abundant, but I continue to be amazed that senior researchers often write about things like “specificity” and “sensitivity” as if they are not context-dependent. […]

In the stories of Russia 120 years ago, by Turgenev, Chekhov and Tolstoy, there is a recurring scene: the landowner or his bailiff meets a crowd of discontented peasants and eventually placates them by handing around buckets of vodka. […]

The kidney is really just a sophisticated extension of the cardiovascular system, and in end-stage cardiac disease, measures of renal function provide the strongest prognostic markers (apart from B-type natriuretic peptide). […]
Plant of the Week: Geranium x Magnificum
When I first started writing about plants in these reviews, I concentrated on neglected treasures, until a reader complained that he could never find a single plant I described. […]

Nothing illustrates the abasement of primary care in the UK better than the saga of chronic kidney disease and the estimation of glomerular filtration rate. On the flimsiest clinical evidence we were ordered to tell all our patients with an eGFR under 60 that their kidneys might pack up, and collect a few pence for […]

“Read, mark, learn and inwardly digest” is a phrase the teachers of my youth liked to use (it comes from Cranmer’s Collect for Bible Sunday, in the Book of Common Prayer). That’s what we need to do with articles about diseases we don’t come across often but shouldn’t miss […]

Another negative trial of homocysteine-lowering therapy: this is a substudy of HOPE-2 and shows that oral supplements of folic acid, pyridoxine and cobalamin lower HCy but do not reduce venous thromboembolism. […]
