Is plasma neutrophil gelatinase-associated lipocalin an early biomarker for acute kidney injury in an adult ICU population?
Plasma NGAL is a useful early marker for AKI in a heterogeneous adult ICU population, in which the timing of renal insult is largely unknown. It allows the diagnosis of AKI up to 48 h prior to a clinical diagnosis based on AKI consensus definitions. Additionally, it predicts need for RRT and correlates with AKI severity. Early identification of high risk patients may allow potentially beneficial therapies to be initiated early in the disease process before irreversible injury occurs.
One out of 4 older people reported at least a fall in the last year. This study demonstrates that fear of falling, depressive symptoms and basic disability are independent variables associated with previous falls. These 3 factors can lead to a flattering spiral of falling and may be potential targets for effective functioning in the context of falls.
