Acute kidney injury (AKI) is common among critically ill patients and results in increased mortality in this population. This review focuses on the diagnosis and management of AKI. The authors first explore new aspects of diagnosis, including new criteria that take into account even modest changes in renal function, and the development of novel biomarkers(More)
AIMS We derived and validated a clinical prediction rule that can be used to predict post-stroke pneumonia. METHODS We conducted a retrospective cohort study of patients admitted to hospital with a stroke. The cohort was subdivided into a derivation group and a validation group. Within the derivation group, a point scoring system was developed to predict(More)
Hypertension and chronic volume overload are complications often seen in hemodialysis patients. Current hemodialysis practices adopt a standard dialysate sodium prescription that is typically higher than the plasma sodium concentration of most patients. As a general rule, hemodialysis patients have stable predialysis plasma sodium concentrations, and each(More)
The physical examination has a historically prominent role in medical practice, being an important tool in diagnosis and in developing rapport with patients. Yet, physicians have lost bedside skills in recent years, with increasing use of technology at the expense of time spent with the patient. This is concerning, especially in the present era of(More)
BACKGROUND The treatment of hypertension is an essential component of stroke prevention; however, the clinical management of patients with cerebrovascular disease is complicated by orthostatic hypotension (OH). The primary objectives were to: determine the prevalence of OH in a stroke outpatient clinic; describe categories of OH; and identify factors(More)
BACKGROUND Adjudication of patient outcomes is a common practice in medical research and clinical trials. However minimal data exists on the adjudication process in the setting of Acute Kidney Injury (AKI) as well as the ability to judge different etiologies (e.g. Acute Tubular Necrosis (ATN), Pre-renal Azotemia (PRA)). METHODS We enrolled 475 consecutive(More)
Falls are a serious medical complication following stroke. The objectives of this study were to (1) confirm the prevalence of falls among patients with stroke during acute hospitalization, (2) identify factors associated with falls during the acute stay, and (3) examine whether in-hospital falls were associated with loss of function after stroke (new(More)

NEW FINDINGS What is the central question of this study? Can the change in plasma arginine vasopressin concentration (P[AVP] ) in response to osmotic stimulation (POsm ) serve as a biomarker for NMDA receptor signalling in schizophrenia and depression and thereby distinguish between these mental illnesses? What is the main finding and its importance? In(More)
