delirium is a frequent neuropsychiatric syndrome affecting medical and surgical elderly patients. Cholinergic dysfunction has been implicated in delirium pathophysiology and plasmatic acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) activities are suppressed in patients with delirium. In this cohort study, we investigated whether these changes emerge during delirium or whether they are present before its onset. ⋯ plasma cholinesterase activity can be a useful candidate biomarker to identify subjects at greater risk of developing postoperative delirium.

Randomized Controlled Trial Multicenter Study
Non-invasive ventilation in elderly patients with acute hypercapnic respiratory failure: a randomised controlled trial.
older patients usually receive less invasive and costly hospital care, even if they meet the criteria for Intensive Care Unit admission or have a 'do not intubate'(DNI) order. The aim of this randomised, controlled trial was to assess the effectiveness of non-invasive mechanical ventilation (NIV) versus the standard medical therapy (SMT) in reducing the need of intubation, improving survival and reducing respiratory distress in very old patients with acute hypercapnic respiratory failure (AHRF). ⋯ compared with SMT, NIV decreased the rate of meeting the ETI criteria and the mortality rate of very old patients with AHRF. NIV should be offered as an alternative to patients considered poor candidates for intubation and those with a DNI order.

in Auckland, New Zealand in 1988, 7.7% of those aged over 65 years lived in licenced residential aged care. Age-specific rates approximately doubled for each 5-year age group after the age of 65 years. Even with changes in policies and market forces since 1988, population increases are forecast to drive large growth in demand. This study shows previously unrecognised 20-year trends in rates of care in a geographically defined population. ⋯ growth predicted in the residential aged care sector is not yet evident. The introduction of standardised needs assessments before entry, increased availability of home-based services, and growth in retirement villages may have led to reduced utilisation.
