Repeat thyroid function tests for healthy older people are not needed

Older adults with normal thyroid function or subclinical thyroid dysfunction show notable long-term stability of their thyroid hormone levels. This suggests that it is safe for GPs not to routinely retest older adults unless they have risk factors or develop clinical symptoms of overt thyroid dysfunction. Over five years, about 0.2% older adults with normal ...

Low dose aspirin only appears to be effective at preventing stroke or heart attack for people weighing less than 70kg, while higher doses are better for people who weigh over 70kg. Researchers analysed data from 13 trials of aspirin for primary or secondary prevention of cardiovascular events, totalling over 115,000 participants. They found that 75 ...

Aspirin did not prevent deaths or disability in healthy older adults

In the ASPREE trial, older adults with no apparent cardiovascular disease who took daily aspirin saw no benefit in terms of reducing the chance of dying or having dementia or disability. Instead, it slightly increased their mortality and bleeding risk - aspirin was associated with an excess of 1.6 deaths per 1,000 people per year. ...

Complications following hip or knee surgery are more likely for people with long-term illness, but benefits are still worthwhile

People with long-term illness are just as likely to benefit from knee or hip surgery as those without. However, they are more likely to have complications following surgery and to be readmitted within three months. This study reviewed data from 70 studies to determine the chance of short-term harms and long-term benefits linked to 11 ...

Supervised exercise sessions increase physical activity and fitness of cancer survivors

Aerobic exercise and resistance sessions that include supervision help people living with cancer to meet guideline physical activity levels. Common behaviour change techniques that were shown to increase physical activity are goal setting, graded tasks (e.g. increasing exercise duration or intensity over time), and instruction on how to perform particular exercises. This review update looked ...
