Nurses have expanded and developed their roles to meet the needs of patients. This review evaluates the safety, effectiveness and health outcomes of nurses practising in autonomous roles, using advanced practice skills, within the context of a dedicated bronchiectasis clinic. ⋯ This review has found one trial that does not demonstrate significant differences in clinical outcomes between nurse led care and doctor led care within the setting of a specialist clinic is, but there may be increased cost implications. Further research is required to review whether nurse led care provides the same outcomes in the community or secondary care setting.

ReviewEarly intravenous nutrition for the prevention of neonatal jaundice.
The early institution of enteral feeding in the first few days of life is known to impact on the development of unconjugated hyperbilirubinaemia. However, the effect of early intravenous nutrition on neonatal jaundice remains unknown. ⋯ Decisions regarding the institution of early intravenous nutrition must continue to be based upon factors others than its effect on neonatal jaundice.

Review Meta AnalysisAntiplatelet and anticoagulation for patients with prosthetic heart valves.
Patients with prosthetic heart valves are at increased risk for valve thrombosis and arterial thromboembolism. Oral anticoagulation alone, or the addition of antiplatelet drugs, has been used to minimize this risk. An important issue is the effectiveness and safety of the latter strategy. ⋯ Adding antiplatelet therapy, either dipyridamole or low-dose aspirin, to oral anticoagulation decreases the risk of systemic embolism or death among patients with prosthetic heart valves. The risk of major bleeding is increased with antiplatelet therapy. These results apply to patients with mechanical prosthetic valves or those with biological valves and indicators of high risk such as atrial fibrillation or prior thromboembolic events. The effectiveness and safety of low dose aspirin (100 mg daily) appears to be similar to higher dose aspirin and dipyridamole.

Review Meta AnalysisInhaled nitric oxide for acute hypoxemic respiratory failure in children and adults.
Acute hypoxemic respiratory failure affects all age groups and may result from a number of systemic diseases. It continues to be associated with high mortality and morbidity. Initial studies examining the effect of inhaled nitric oxide in respiratory failure demonstrated transient improvement in oxygenation but did not examine mortality or other significant morbidity outcomes. ⋯ Nitric oxide did not demonstrate any statistically significant effect on mortality and transiently improved oxygenation in patients with hypoxemic respiratory failure. Lack of data prevented assessment of other clinically relevant end points. If further trials comparing inhaled nitric oxide with an inhaled placebo are to proceed, they should be stratified for primary disease, assess the impact of other combined treatment modalities for respiratory failure, and must specifically evaluate clinically relevant outcomes, before any benefit of inhaled nitric oxide for respiratory failure can be excluded.

Dementia with Lewy bodies (DLB) was first described in 1983, and clinical diagnostic criteria were published in the early to mid 1990s. It has been suggested DLB may account for up to 15-25% of cases of dementia among people aged over 65, although autopsy suggests much lower rates. Characteristic symptoms are dementia, marked fluctuation of cognitive ability, early and persistent visual hallucinations and spontaneous motor features of Parkinsonism. Falls, syncope, transient disturbances of consciousness, neuroleptic sensitivity, and hallucinations in other modalities are also common. This combination of features can be difficult to manage as neuroleptics can make the Parkinsonian and cognitive symptoms worse. There is evidence to suggest that the cholinesterase inhibitors may be beneficial in this disorder; small case series indicate that cholinesterase inhibitors are safe, and will improve both cognitive deficits and neuropsychiatric symptoms in DLB. ⋯ Patients with dementia with Lewy bodies who suffer from behavioural disturbance oS CONCLUSIONS: Patients with dementia with Lewy bodies who suffer from behavioural disturbance or psychiatric problems may benefit from rivastigmine if they tolerate it, but the evidence is weak. Further trials using rivastigmine are needed, as are trials of other cholinesterase inhibitors in dementia with Lewy bodies.
