Aspirin lowers heart attack risk but may cause severe internal bleeding

People without heart disease who take a daily aspirin may lower their risk of a heart attack or stroke, but a new study confirms they also have an increased risk of severe internal bleeding.

US doctors have long advised adults who have not had a heart attack or stroke but are at high risk for these events to take a daily aspirin pill, an approach known as primary prevention. Even though there is clear evidence aspirin works for this purpose, many physicians and patients have been reluctant to follow the recommendations because of the risk of rare but potentially fatal internal bleeding.

For the current study, researchers examined data from 13 clinical trials testing the effects of aspirin against a placebo or no treatment in more than 164,000 adults.

"The results demonstrate that there are cardiovascular benefits, but that they are quite closely matched by increased risks of serious bleeding," said lead study author Dr Sean Zheng of King's College London and Imperial College London.


Forum: Crack down on lack of decorum

The lack of decorum is not limited to young pupils at concert halls (Educate students on decorum at performances; Jan 22).

We see examples of it everywhere:
  • People speaking loudly among themselves or on their phones in public spaces such as trains.
  • Children treating public spaces as playgrounds and creating a din, without their guardians stepping in to control them.
  • People wearing foul-smelling and dirty clothes in public.
  • Bus and train commuters playing loud music or games without using headsets.

If Singapore wants to be home to world-class behaviour, much more needs to be done, beyond just demanding that teachers educate and discipline their students.

Parents and guardians must rein in misbehaving children immediately.

Public transport operators and the owners of buildings where people congregate must put up posters reminding the public of the expected decorum. They can also make use of periodic public announcements, like how it is done on Japanese public transport.

Only then can Singaporeans live and work peacefully.

Gum disease may cause premature labour

A study of dozens new mothers found 45% of those whose waters broke early had swollen, sore or infected gums.

In comparison, only 29% of the women who did not give birth prematurely had signs of gum disease.

Bacteria in plaque are thought to travel to the placenta via the bloodstream, causing it to became inflamed.

Having gum disease 'raises your risk of Alzheimer's

Scientists have found for the first time that bacteria which cause bleeding gums can get from the mouth into the brain.

Signs of this gum disease bacteria were found in the brains of 51 out of 53 people with Alzheimer's disease.

The findings suggest that people who brush their teeth properly could lower their risk of dementia.

However, it raises concerns for the 45% of people in Britain who already have gum disease and may be at greater risk.
