Is there such a thing as too much exercise?

Many middle-aged marathon runners and other endurance athletes are familiar with concerns from their loved ones – and occasionally their physicians – that they might be exercising too much and straining or harming their hearts.

For all of them, a large-scale study published recently in JAMA Cardiology should be mollifying. It finds that middle-aged men who work out often and vigorously do tend to develop worrisome plaques in their cardiac arteries.

But those men also are less likely than more sedentary people to die prematurely from a heart attack or other cause.

In essence, these results suggest that large amounts of exercise can up someone’s risk of developing plaques, while also lessening the likelihood that he will die from a heart attack precipitated by those plaques, said Dr Laura DeFina, the chief science officer for the Cooper Institute, who led the study.

Doctors need not list all possible side effects of drugs or treatment: MOH

The case of the orthopedic surgeon who was fined S$100,000 — and the severity of the punishment which triggered an outcry among the medical community — received an airing in Parliament on Monday (Feb 11), with Senior Minister of State for Health Lam Pin Min saying there could be a review of disciplinary processes and the sentencing framework for errant doctors.

He clarified that the outcome of the case, in which orthopaedic surgeon Lim Lian Arn pleaded guilty to failing to inform his patient of the complications that could arise from a steroid injection that he was giving her, did not mean that a doctor must lay out “every possible side effect and potential complications” of a drug or treatment.

“Dr Lim admitted that he was guilty of failing to inform the patient of any risks and complications; he was not found guilty for failing to inform the patient of all possible complications that could arise from the H&L Injection.”

The Singapore Medical Council, which levied the maximum S$100,000 fine on Dr Lim, said the same about two weeks ago, when it reassured doctors here that they only need to convey “relevant and material” information to their patients and do not need to inform them of all possible complications of a treatment or procedure.

Not feasible to mark GCE-level exam scripts locally: Ong Ye Kung

It is not possible to have all GCE-level examination scripts marked locally bearing in mind the wellbeing of teachers, due to the large number to be marked over a short period of time during the school vacation, said Education Minister Ong Ye Kung on Monday (Feb 11).

Each year, there are about 1.1 million answer scripts generated in the GCE-level examinations. Of these, 300,000 — that of mother tongue languages, social studies and coursework components — are marked locally. The remaining 800,000 are marked by Cambridge Assessment.

Cambridge Assessment relies on about 2,200 professors and experienced educators from universities and higher institutions to mark the scripts.

With a tight timeline between the exams and release of results, the authorities need to be “mindful (of) the workload and wellbeing” of teachers, if all subjects were to be marked locally over the school vacation period, he said.
