To summarize recent evidence on prevalence, risk factors, significance, treatment, and prevention of electrolyte disorders in critically ill with a specific focus on disorders during the initiation of nutrition.
Electrolyte disturbances appear to occur often during critical illness, and most of them seem to be associated with impaired outcome. However, a recent systematic review indicated insufficient evidence to answer clinically relevant questions regarding hypophosphatemia. Similar questions (which thresholds of serum levels are clinically relevant; how serum levels should be corrected and how do different correction regimens/approaches influence outcome) are not clearly answered also for other electrolytes. The most crucial feature of electrolyte disturbances related to feeding is refeeding syndrome. Recent evidence supports that additionally to the correction of electrolyte levels, a temporary restriction of calories (reducing the magnitude of this metabolic feature, including electrolyte shifts) may help to improve outcome.
Diverse electrolyte disorders often occur in critically ill patients. Hypophosphatemia, hypokalemia, and hypomagnesemia that are encountered after initiation of feeding identify refeeding syndrome. Along with correction of electrolytes, reduction of caloric intake may improve the outcome of the refeeding syndrome.

Circulatory shock is associated with reduced splanchnic blood flow and impaired gut epithelial barrier function (EBF). Early enteral nutrition (EN) has been shown in animal models to preserve EBF. There are limited human data informing early EN in circulatory shock and critical care nutrition guidelines provide disparate recommendations regarding the optimal timing and dose. The purpose of this review is to describe the harms and benefits of early EN in circulatory shock by identifying and appraising recent human data.
The cumulative risk of nonocclusive bowel ischemia and necrosis in patients with circulatory shock is no higher than 0.3% across observational and randomized controlled trial-level data, and whether the risk is increased by EN delivery remains uncertain. JNJ-64264681 datasheet Observational data suggest that early EN in circulatory shock is associated with improved clinical outcomes but data from robust randomized controlled trials remain equivocal, so the optimal timing and dose remain unknown.
Based on the best available data, initiating restrictive dose EN into the stomach after initial resuscitation in patients with circulatory shock does not appear to be harmful. In fact, early EN may preserve EBF and improve clinical outcomes.

Repeated measures analysis of covariance and three-way analysis of variance with repeated measures are common statistical methods. For a valid interpretation of blood pressure (BP) response to exercise, a variety of additional statistical methods must be implemented. Four additional statistical methods are presented technical error of measurement (SEM), smallest real difference (SRD), magnitude-based inference and mixed effect modeling technique (MEM). The aim of this perspective article is to demonstrate how to apply already known statistical analyses regarding BP responsiveness in order to improve interpretation and achieve higher reliability for future studies in exercise science.
A total of 27 hypertensive older women (aged 68.37 ± 5.55 years) participated in the present study. A whole-body resistance training (RT) program was performed on two nonconsecutive days per week for 10 weeks. BP was monitored during the 10-week RT intervention and after 15 weeks of detraining. First, individuals were classified as high and low responders, then statistical methods to analyze data included the use of SEM, SRD, magnitude-based inference and MEM.
When magnitude-based inference was used to classify responsiveness, most participants displayed a trivial response. Decrements in SBP between 1 and 10 mmHg were not clinically meaningful but fell within the measurement error of the SBP measurements. Baseline SBP and time of training predicted post-SBP response.
Changes over time and declines in SBP might not be a SRD and fell in the SEM. Moreover, SBP responsiveness was the result of inappropriate control of covariates such as period of training.

This study was designed to demonstrate the predictive ability of quantitative indocyanine green (ICG) fluorescence angiography for the short-term postoperative outcome, the occurrence of delayed graft function (DGF), and long-term graft survival.
DGF is a relevant problem after kidney transplantation; sufficient microperfusion of the allograft is crucial for postoperative organ function. Fluorescence angiography with ICG can serve as an intraoperative quality control of microperfusion.
This prospective diagnostic study, conducted in two German transplantation centers from November 2015 to October 2018, included 128 consecutive kidney transplantations. Intraoperative assessment of the allograft microperfusion was performed by near-infrared fluorescence angiography with ICG; a software was used for quantitative analysis. The associations between perfusion parameters (e.g. ICG Ingress) and donor, recipient, periprocedural, and postoperative characteristics were evaluated.
DGF occurred in 23 (24%) kidney recipients from deceased donors. ICG Ingress (p = 0.0027), donor age (p = 0.0452), recipient age (p = 0.0139) and recipient body mass index (p = 0.0017) were associated with DGF. ICG Ingress correlated significantly with recipient age (r = -0.27662, p = 0.0016), cold and warm ischemia time (r = -0.25204, p = 0.0082; r = -0.19778, p = 0.0283), operating time (r = -0.32208, p = 0.0002), eGFR on postoperative days 1 (r = +0.22674, p = 0.0104) and 7 (r = +0.33189, p = 0.0001). The cutoff value for ICG Ingress was 106.23 AU with sensitivity of 78.3% and specificity of 80.8% (p < 0.0001) for the prediction of DGF.
Fluorescence angiography with ICG allows intraoperative quantitative assessment of microperfusion during kidney transplantation. The parameter ICG Ingress reflects recipient and procedure characteristics and is able to predict the incidence of DGF.
