However, the contribution of these drugs on fall risk has not been quantified on a daily basis among the general population of nursing homes until now.

Not recognising these interferences can lead to misdiagnosis and mismanagement of patients. We present a case of a patient with chest pain and ischaemic risk factors with incongruent biochemical results.

Time horizon dependent characterization factors for acidification were calculated, whereas before only steady-state factors were available. The characterization factors indicate the change in the potential occurrence of plant species due to a change in emission, and they consist of a fate and an effect factor.

This study aimed to differentiate between patients with coronary heart symptoms and healthy subjects with high cholesterol concentrations, using other potential risk factors such as oxidation state, body iron status and the oxidative state of the LDL particle.
Methods: Healthy persons were divided in low cholesterol (<6 mmol/L) (LC) and high cholesterol (> or =6 mmol/L) (HC) groups.
