Targeting histone deacetylases for the treatment of immune, endocrine and metabolic disorders

The 'histone code' is a well-established hypothesis describing the idea that specific patterns of post-translational modifications to histones act like a molecular "code" recognised and used by non-histone proteins to regulate specific chromatin functions. One modification which has received significant attention is that of histone acetylation. The enzymes which regulate this modification are described as histone acetyltransferases or HATs, and histone deacetylases or HDACs. Due to their conserved catalytic domain HDACs have been actively targeted as a therapeutic target. The proinflammatory environment is increasingly being recognised as a critical element for both degenerative diseases and cancer. The present review will discuss the current knowledge surrounding the clinical potential & current development of histone deacetylases for the treatment of diseases for which a proinflammatory environment plays important roles, and the molecular mechanisms by which such inhibitors may play important functions in modulating the proinflammatory environment. © 2009 Bentham Science Publishers Ltd.

Nurses’ views on the implementation of Individualised Medication Administration Guides in patients with dysphagia in care homes

As conditions such as stroke, cancer, Parkinson's disease and Huntingdon's chorea are commonly found in care homes between 15% and 30% of residents in care homes have been found to have difficulties in swallowing their medicines.To address the difficulties associated with administering medicines to patients who cannot swallow (with dysphagia), Individualised Medication Administration Guides (I-MAGs) were introduced by a specialised pharmacist in Care for Elderly wards in a general hospital in East Anglia. The guides contained detailed information about how to administer each medication and they were individualised to the needs of the patient. The I-MAGs were printed in green forms and attached to the medication chart in order to be used in conjunction with it. The ward nurses reported an increase in their confidence when administering medication when I-MAGs were present in the ward. Some patients with I-MAG were discharged to care homes where the I-MAG might have been equally useful. However, the design of such guides is not known to be suitable for care homes environment where they have never been used before. This study aims to explore the opinions of nurses and carers within care homes on the relevance and acceptability of individualised medication administration guides for patients with dysphagia (PWD).
