Improving patient safety for older people in acute admissions: implementation of the Frailsafe checklist in 12 hospitals across the UK.

Background: checklists are increasingly proposed as a means to enhance safety and quality of care. However, their use has been met with variable levels of success. The Frailsafe project focused on introducing a checklist with the aim to increase completion of key clinical assessments and to facilitate communication for the care of older patients in acute admissions.

Using geographical information systems and cartograms as a health service quality improvement tool.

Introduction: Disease prevalence can be spatially analysed to provide support for service implementation and health care planning, these analyses often display geographic variation. A key challenge is to communicate these results to decision makers, with variable levels of Geographic Information Systems (GIS) knowledge, in a way that represents the data and allows for comprehension. The present research describes the combination of established GIS methods and software tools to produce a novel technique of visualising disease admissions and to help prevent misinterpretation of data and less optimal decision making.

Differential feedback modulation of center and surround mechanisms in parvocellular cells in the visual thalamus.

Many cells in both the central visual system and other sensory systems exhibit a center surround organization in their receptive field, where the response to a centrally placed stimulus is modified when a surrounding area is also stimulated. This can follow from laterally directed connections in the local circuit at the level of the cell in question but could also involve more complex interactions. In the lateral geniculate nucleus (LGN), the cells relaying the retinal input display a concentric, center surround organization that in part follows from the similar organization characterizing the retinal cells providing their input.

Assessment of 180° rotation of the choroid as a novel surgical treatment for age-related macular degeneration.

Purpose: Our objective was to examine the feasibility of rotating choriocapillaris, Bruch's membrane (BM), and retinal pigment epithelium (RPE) through 180° on a vascular pedicle and to assess revascularization and tissue preservation postoperatively. Such an approach could be used in the treatment of age-related macular degeneration where there is focal disease at the macula with healthy tissues located peripherally.

Methods: Successful surgery was performed in six rhesus macaque monkeys, which have a very similar choroidal blood supply to humans.
