Prostate cancer screening: Committee says no to testing all men The UK National Screening Committee said there were more harms than benefits to using the PSA test for screening all men.

#ProstateCancer screening: Committee says no to testing all men

Bernard Rachet tells the Standard recommendations show urgent need for effective test or screening strategy that doesn't generate large numbers of false positives & add to burden on #NHS.

Le vaccin proposé contre la grippe pour les enfants en Angleterre est un spray nasal (et non une injection contrairement à la France), il est gratuit, et proposé proactivement à tous les enfants par courrier ou SMS aux parents, ce qui explique le meilleur taux de couverture.

Curious to hear from people: it is common in research to give an Amazon voucher to participants (e.g. Delphi surveys). Do you see an ethical issue with it (because, well, it's Amazon) and if so, what could be a more ethical alternative (that can be used from any country)?
