Irradiation of spinal metastases: should we continue to include one uninvolved vertebral body above and below in the radiation field?
Isolated local failures of the unirradiated adjacent vertebral bodies may occur in<5% of patients with isolated spinal metastasis. On the basis of the data, the current practice of irradiating one vertebral body above and below seems unnecessary and could be revised to irradiate only the involved level(s) of the spine metastasis.
This study suggests that a liberal intake of energy may decrease the risk of developing frailty in the elderly without increasing the risk of developing obesity, diabetes, hypertension or hyperlipidaemia. Caution should remain however in the prescription of diets high in saturated fat as the link established with hyperlipidaemia in young adults appears to be consistent in the elderly. Further research is required to explore the optimal sources of energy for a liberalised diet and the effect of a liberalised diet on other diet related health conditions.
