ABSTRACT
BACKGROUND AND PURPOSE: Apathy is an important neuropsychiatric feature of Parkinson's disease (PD), which often emerges before the onset of motor symptoms. Patients with rapid eye movement sleep behaviour disorder (RBD) have a high probability of developing PD in future. Neuropsychiatric problems are common in RBD, but apathy has not previously been detailed in this key prodromal population. METHODS: Eighty-eight patients with polysomnographically proven RBD, 65 patients with PD and 33 controls were assessed for apathy using the Lille Apathy Rating Scale. Cognition and depression were also quantified. The sensitivity of the Unified Parkinson's Disease Rating Scale screening questions for apathy and depression was calculated. RESULTS: A total of 46% of patients with RBD were apathetic, compared with 31% of patients with PD in our sample. Most patients with RBD with depression were apathetic but more than half of apathetic patients were not depressed. The sensitivity of the single Unified Parkinson's Disease Rating Scale screening question was only 33% for mild apathy and 50% for severe apathy. CONCLUSIONS: Apathy is common in RBD and is underestimated by a single self-report question. Recognition of apathy as a distinct neuropsychiatric feature in RBD could aid targeted treatment interventions and might contribute to the understanding of prodromal PD.

BACKGROUND.: Prolonged invasive mechanical ventilation (IMV) is a frequent challenge, and an increasing number of patients are transferred from intensive care units to long-term acute care hospitals or specialized weaning units. There are few published data for discharge home rates, use of noninvasive ventilation (NIV), or long-term survival. METHODS.: A case-note and database review was conducted of patients admitted to a UK national specialized weaning unit for weaning from IMV between 1992 and 2012. Patients were grouped into diagnostic categories according to the predominant cause of weaning failure. Weaning outcomes and long-term survival were assessed according to diagnostic group and mode of ventilation on discharge. RESULTS.: Four hundred and fifty-eight patients were transferred for weaning from IMV. Four hundred and seventeen (91%) survived to hospital discharge, of whom at least 343 (82%) were ultimately discharged to their own home. Three hundred and thirty (72%) weaned from IMV, of whom 142 weaned from all ventilation and 188 weaned to nocturnal NIV. Weaning success was highest for patients with chronic obstructive pulmonary disease and chest wall disorders. Median survival from unit discharge was 25 months (interquartile range 5-74), with the longest survival seen for patients discharged with nocturnal NIV [37 (12-81) months]. CONCLUSIONS.: These results confirm successful weaning outcomes for patients transferred to a specialized weaning and long-term ventilation service. In contrast to other service models, most patients achieved discharge to their own home.

Twenty-two asymptomatic women with rising CA 125 levels after chemotherapy for ovarian cancer were entered into a trial of isotretinoin combined with calcitriol. Tumours were evaluated according to precise criteria based on serial CA 125 levels and by comparing regression slopes of CA 125 before and during therapy. There was no evidence based on CA 125 of any responses or significant change in tumour growth rate.
