ReviewCerebrospinal fluid biomarkers of neurodegeneration in chronic neurological diseases.
Chronic neurological diseases (CND) like amyotrophic lateral sclerosis (ALS), dementia or multiple sclerosis (MS) share a chronic progressive course of disease that frequently leads to the common pathological pathway of neurodegeneration, including neuroaxonal damage, apoptosis and gliosis. There is an ongoing search for biomarkers that could support early diagnosis of CND and help to identify responders to interventions in therapeutic treatment trials. Cerebrospinal fluid (CSF) is a promising source of biomarkers in CND, since the CSF compartment is in close anatomical contact with the brain interstitial fluid, where biochemical changes related to CND are reflected. We review recent advances in CSF biomarkers research in CND and thereby focus on markers associated with neurodegeneration.

ReviewEarly diagnosis of acute kidney injury in critically ill patients.
Acute kidney injury (AKI) is a common and serious problem in critically ill patients. Tests currently used to detect AKI (i.e., serum creatinine, serum urea and various urinary indices) often result in delayed detection of injury--becoming abnormal at 48-72 h after the initial insult. ⋯ The development of novel serum and urinary biomarkers capable of detecting AKI at an earlier phase of illness is therefore vital. This article will review the pitfalls of current conventional testing in kidney injury and discuss the emergence of novel biomarkers with the potential to revolutionize the field of critical care nephrology.
