ReviewAKI in the ICU: definition, epidemiology, risk stratification, and outcomes.
Acute kidney injury (AKI) has emerged as a major public health problem that affects millions of patients worldwide and leads to decreased survival and increased progression of underlying chronic kidney disease (CKD). Recent consensus criteria for definition and classification of AKI have provided more consistent estimates of AKI epidemiology. Patients, in particular those in the ICU, are dying of AKI and not just simply with AKI. ⋯ The detrimental effects of AKI are not limited to classical well-known symptoms such as fluid overload and electrolyte abnormalities. AKI can also lead to problems that are not readily appreciated at the bedside and can extend well beyond the ICU stay, including progression of CKD and impaired innate immunity. Experimental and small observational studies provide evidence that AKI impairs (innate) immunity and is associated with higher infection rates.

Despite the availability of renal replacement therapy, acute kidney injury (AKI) is associated with high mortality and morbidity. In humans, it is difficult to determine whether AKI is a cause or consequence of excess morbidity. In animal models, however, it is increasingly clear that AKI induces distant organ dysfunction. ⋯ Specifically, growing evidence implicates renal injury as an instigator and multiplier of pulmonary, cardiac, hepatic, and neurologic dysfunction. Accurate identification of these pathways will be critical in developing targeted therapies to improve outcomes in AKI. The purpose of this review is to summarize both clinical and preclinical studies of AKI and its role in distant organ injury.

ReviewA systematic review of RIFLE criteria in children, and its application and association with measures of mortality and morbidity.
The RIFLE criteria were developed to improve consistency in the assessment of acute kidney injury. The high face validity, collaborative development method, and validation against mortality have supported the widespread adoption of the RIFLE to evaluate adult patients; however, its inconsistent application in adult studies is associated with significant effects on the estimated incidence of acute kidney injury. ⋯ Limited and conflicting associations between the RIFLE and mortality, length of stay, illness severity, and measures of kidney function were found. Thus, although the RIFLE was developed to improve the consistency of defining acute kidney injury, there are still major discrepancies in its use in pediatric patients that may undermine its potential utility as a standardized measure of acute kidney injury in children.

ReviewA mission in evolution: the International Society of Nephrology in the past 10 years--2001-2010.
The International Society of Nephrology is now 50 years old. It has dedicated the year 2010 to celebrate its Gold Anniversary in many ways, including documentation of its progress during the past decade, following an earlier article addressing the period 1960-2000. The present article describes the changing mission of the Society in the direction of achieving its ultimate vision of "global elimination of kidney disease." While maintaining its leadership in the promotion of science, it became the prime driving force in capacity building for the diagnosis, prevention and management of kidney disease in the developing world. ⋯ This required the acquisition of new skills in publishing, marketing, politics and fund-raising, which could only be handled by professional management, which the Society has utilized since 2003. It also necessitated enlargement of the leadership circle to include members from all over the world, for which reason the constitution had to be amended twice during the past decade, and the bylaws re-written in 2007. The pride that International Society of Nephrology takes from its scientific and outreach achievements is the fuel that drives its machinery to endless horizons in the humanitarian arena.

ReviewDo meta-analyses in nephrology change the way we treat patients?
There has been an exponential increase in the number of nephrological meta-analyses published, but their relative contribution to the nephrology literature is unclear and their influence on physician behavior and evidence-based patient care is poorly understood. We studied the nephrology literature, point-of-care resources, guidelines, and a questionnaire survey of the New York Society of Nephrology membership to understand the role and perception of meta-analyses in nephrology. ⋯ The results of our practitioner survey and our review of the nephrology literature suggest an increasing influence at the level of the individual practitioner of meta-analyses. This underlines the need to develop a better understanding of the contributions and role of meta-analyses in the literature.
