Does intravenous glutamine supplementation to head trauma patients leave cerebral glutamate concentration unaffected?
Intravenous glutamine in clinically relevant doses leaves cerebral glutamate unaffected. This opens the possibility of evaluating the effects of i.[Symbol: see text]v. glutamine supplementation upon outcome for neurosurgical ICU patients.
There is some evidence that case management is beneficial at improving some outcomes at certain time points, both in the person with dementia and in their carer. However, there was considerable heterogeneity between the interventions, outcomes measured and time points across the 13 included RCTs. There was some evidence from good-quality studies to suggest that admissions to care homes and overall healthcare costs are reduced in the medium term; however, the results at longer points of follow-up were uncertain. There was not enough evidence to clearly assess whether case management could delay institutionalisation in care homes. There were uncertain results in patient depression, functional abilities and cognition. Further work should be undertaken to investigate what components of case management are associated with improvement in outcomes. Increased consistency in measures of outcome would support future meta-analysis.
