Malnutrition is common in patients with heart failure (HF) and is associated with poor prognosis. We evaluated the prognostic and clinical impact of a nutritional intervention in malnourished patients with chronic HF. ⋯ In patients with chronic HF and some degree of malnutrition, individualized nutritional intervention may reduce the risk of all-cause mortality or HF hospitalisations and improve nutritional status and functional capacity. These results underline the need for further randomized controlled trials with this approach to confirm the potential prognostic benefit.

The objective was to evaluate its effectiveness for the early diagnosis of dementia in patients with mild cognitive impairment (MCI). ⋯ There is insufficient evidence to recommend routine brain MRI for the early diagnosis of dementia in patients with MCI.
