Sepsis is considered today a major public health problem. Despite that mortality has been consistently associated with organ compromise, the mechanisms by which sepsis causes multiple organ dysfunction are not well understood, and hence, therapy remains reactive and non-specific. ⋯ This finding suggests that mechanisms other than hypoperfusion may be at play, and that adaptive responses of the tubular epithelial cell may be key to understanding the origin of organ dysfunction in the setting of sepsis. In this review, we discuss evidence suggesting that the activation of energy regulatory processes and mitochondrial quality control processes may not only be drivers of this response, but also be factors that may alter the course of organ dysfunction during sepsis in clinically relevant ways.

Review Meta Analysis
Effect of ultrafiltration versus intravenous furosemide for decompensated heart failure in cardiorenal syndrome: a systematic review with meta-analysis of randomized controlled trials.
Ultrafiltration is an adjunctive treatment for decompensated heart failure patients with cardiorenal syndrome. The efficacy and safety of ultrafiltration in the patient cohort are still unknown. ⋯ Ultrafiltration is a safe and effective strategy in the treatment of cardiorenal syndrome without increasing the risk of renal deterioration.

The study of acute kidney injury (AKI) has expanded with the increasing availability of electronic health records and the use of standardized definitions. Understanding the impact of AKI between settings is limited by heterogeneity in the selection of reference creatinine to anchor the definition of AKI. In this mini-review, we discuss different approaches used to select reference creatinine and their relative merits and limitations. ⋯ Choosing reference creatinine for AKI calculation is important for AKI classification and study interpretation. We recommend obtaining data on pre-hospital kidney function, wherever possible. In studies where surrogate estimates are used, transparency in how they are applied and discussion that informs the reader of potential biases should be provided. Further work to refine the estimation of reference creatinine is needed.

Recent technical advances in the stem cell field have enabled the in vitro generation of complex structures resembling whole organs termed organoids. Most of these approaches employ three-dimensional (3D) culture systems that allow stem cell-derived or tissue progenitor cells to self-organize into 3D structures. ⋯ Here, we outline historical advances in the field and describe some of the major recent developments in 3D human organoid formation. Finally, we underline current limitations and highlight examples of how organoid technology can be applied in biomedical research.

Electronic health records (EHRs) have become an integrated part of medical practice in most clinical settings around the world. Appropriate use of EHR potentially improves patient care while poorly designed EHR can cause harm. In recent years, EHR has been used as a platform to identify patients who have or may develop acute kidney injury (AKI). ⋯ Appropriate utilization of intelligent EHR can provide timely, appropriate and accurate information to the clinicians in order to improve the quality of care provided to critically ill patients and assist investigators to generate new knowledge. In this review paper, we discuss the past and present states of EHR role in the field of AKI. We also share our views regarding the future potentials and directions of these devices.
