Bladder warning for recreational drug users, earlier blood testing for Alzheimer’s and are UK women in denial about their health?

One fifth of patients on hospital drips develop complications because they are not given the right fluid levels, writes the BBC.

NICE said nurses and doctors need better training on giving fluids intravenously because too much fluids can lead to heart failure and too little to kidney problems.

Also on the BBC, the drug Ketamine – also used as an animal tranquilizer – may be reclassified as class B rather than class C because of its detrimental effect on the bladder.

The Advisory Council on the Misuse of Drugs is set to make the recommendation after new evidence was revealed, uncovering severe cases where habitual users had to have their bladders removed.

Scientists are close to developing a blood test that could diagnose Alzheimer’s disease at an early stage, reports the Telegraph.

The researchers, at Kings College London, said the findings could be used in clinical trials to develop new drugs for the condition.

Meanwhile, the Daily Mail is asking whether British women are in denial about their health after EU statistics revealed they were more likely to rate themselves as healthy than other Europeans – despite tending to suffer worse health.
