BACKGROUND: Substantial morbidity and excessive care variation are seen with pediatric pneumonia. Accurate risk-stratification tools to guide clinical decision-making are needed. METHODS: We developed risk models to predict severe pneumonia outcomes in children (<18 years) by using data from the Etiology of Pneumonia in the Community Study, a prospective study of community-acquired pneumonia hospitalizations conducted in 3 US cities from January 2010 to June 2012...

Over the past half century, coronary care units have expanded from specialized ischemia arrhythmia monitoring units into intensive care units (ICUs) for acutely ill and medically complex patients with a primary cardiac diagnosis. Patients admitted to contemporary coronary intensive care units (CICUs) are at risk for common and preventable critical care complications, yet many CICUs have not adopted standard-of-care prevention protocols and practices from general ICUs. In this article, we (1) review evidence-based interventions and care bundles that reduce the incidence of ventilator-associated pneumonia, excess sedation during mechanical ventilation, central line infections, stress ulcers, malnutrition, delirium, and medication errors and (2) recommend pragmatic adaptations for common conditions in critically ill patients with cardiac disease, and (3) provide example order sets and practical CICU protocol implementation strategies...

BACKGROUND: Metabolic acidosis frequently is present in surgical patients; however, different types of metabolic acidosis (hyperlactatemia, hyperchloremia, and others) may have different relationships to perioperative outcomes. We hypothesized that in postoperative surgical patients, distinctive types of metabolic acidosis would correlate differently with the outcomes of high-risk surgeries. METHODS: A prospective, multicenter observational study was performed in 3 different tertiary care hospitals...

Cardiovascular (CV) risk assessment is not easy in chronic kidney disease (CKD) patients. Age, male sex, race, family history of CV disease, smoking status and diabetes should be considered as CV risk factors as the general population. It is also accepted that hypertension (HTN) is associated with the greater risk of CV complications in this population. However, there are some concerns in this issue.First, supporting evidence for specific blood pressure (BP) targets in CKD is scarce. Many observational studies reported a J-shaped association between BP level and CV mortality unlike a linear association in the general population...

BACKGROUND: Normal saline (NS) is the most commonly used crystalloid solution worldwide but contains an excess of chloride and may cause metabolic acidosis and hyperchloraemia. Such abnormalities may be attenuated by the use of a balanced solution such as Plasma-Lyte 148 (PL-148). OBJECTIVE: To assess the feasibility, safety and biochemical and physiological effects of resuscitation with NS versus PL-148 in critically ill patients. DESIGN, SETTING AND PARTICIPANTS: An exploratory, multicentre, doubleblind, randomised controlled trial involving patients aged ≥ 18 years who were prescribed crystalloid fluid resuscitation by the treating clinician between 16 July and 22 October 2015, in three multidisciplinary intensive care units in Melbourne, Victoria, Australia...

BACKGROUND: Meta-analyses based on individual participant data (IPD-MAs) allow more powerful and uniformly consistent analyses as well as better characterisation of subgroups and outcomes, compared to those which are based on aggregate data (AD-MAs) extracted from published trial reports. However, IPD-MAs are a larger undertaking requiring greater resources than AD-MAs. Researchers have compared results from IPD-MA against results obtained from AD-MA and reported conflicting findings...

The central venous pressure, CVP, is an important variable in the management of selected perioperative and intensive care cases and in clinical decision support systems, CDSS. In current routine, when measuring CVP the health care provider may use anatomical landmarks and a spirit level, SL, to adjust the pressure transducer to the level of the tricuspid valve, i.e. the phlebostatic axis. The aim of the study was to assess the agreement in the postoperative setting between the SL method and electromagnetic 3D positioning (EM)...

BACKGROUND: This cohort study compared the prognostic significance of strong ion gap (SIG) with other acid-base markers in the critically ill. METHODS: The relationships between SIG, lactate, anion gap (AG), anion gap albumin-corrected (AG-corrected), base excess or strong ion difference-effective (SIDe), all obtained within the first hour of intensive care unit (ICU) admission, and the hospital mortality of 6878 patients were analysed. The prognostic significance of each acid-base marker, both alone and in combination with the Admission Mortality Prediction Model (MPM0 III) predicted mortality, were assessed by the area under the receiver operating characteristic curve (AUROC)...

Influenza, an infectious respiratory disease, is one of the main causes of excess winter deaths (EWDs) in Europe. Annual flu epidemics are associated with high morbidity and mortality rates, especially among the elderly, those with underlying health conditions and pregnant women. Health Care Workers (HCWs) are also considered at high risk of both contracting influenza and spreading the virus to vulnerable patients. During the 2014/2015 season, the excess winter mortality rates observed in countries of the northern hemisphere (EuroMOMO network) and in Italy (+13%) were strongly related to the intensity of influenza circulation...

PURPOSE: Following repeated weaning failures in acute care services, spinal cord injury (SCI) patients who require prolonged mechanical ventilation and tracheostomy are discharged to their homes or skilled nursing facilities, with a portable mechanical ventilator (MV) and/or tracheostomy tube (TT) with excess risk of complications, high cost and low quality of life. We hypothesized that many difficult-to-wean patients with cervical SCI can be successfully managed in a rehabilitation clinic...

AIM: Hyperchloremic acidosis may have an important role as a precursor of acute kidney injury (AKI) in the hyperchloremic environment induced by chloride-rich fluids, but this remains unclear. We tested the hypothesis that hyperchloremic acidosis assessed by the Stewart approach is associated with postoperative AKI. METHODS: A historical cohort study was conducted in adult patients who had normal renal function preoperatively and required admission to the intensive care unit after elective abdominal surgery...

OBJECTIVES: Low tidal volume (TVe) ventilation improves outcomes for ventilated patients, and the majority of clinicians state they implement it. Unfortunately, most patients never receive low TVes. 'Nudges' influence decision-making with subtle cognitive mechanisms and are effective in many contexts. There have been few studies examining their impact on clinical decision-making. We investigated the impact of 2 interventions designed using principles from behavioural science on the deployment of low TVe ventilation in the intensive care unit (ICU)...

The phosphorus and nitrogen discharge via effluent of intensive trout farming system was quantified through the use of environmental indicators. The nutrient loads, the mass balance, the estimated amount of nutrients in feed and the amount of nutrients converted in fish biomass were calculated based on the concentrations of phosphorus (P) and nitrogen (N) in the feed and in the water. Of the offered feed, 24.75 kg were available as P and 99.00 kg as N, of these, 9.32 kg P (38%) and 29.12 kg N (25%) were converted into fish biomass and 15...

OBJECTIVE: We previously demonstrated a significant reduction in our incidence of chronic lung disease in our NICU using potentially better practices of avoiding delivery room endotracheal intubation and using early nasal CPAP. We sought to demonstrate whether these improvements were sustained and or improved over time. STUDY DESIGN: We conducted a retrospective, cross-sectional analysis of infants 501-1500 grams born at our hospital between 2005 and 2013. Infants born during the 2005-2007, 2008-2010 and 2011-2013 epochs were grouped together, respectively...

INTRODUCTION: Acute liver failure (ALF) is an ideal condition for use of a checklist. Our aims were to develop a checklist for the management of ALF in the intensive care unit (ICU) and assess the usability of the checklist among multiple providers. METHODS: The initial checklist was developed from published guidelines and expert opinion. The checklist underwent pilot testing at 11 academic liver transplant centers in the US and Canada. An anonymous, written survey was used to assess the usability and quality of the checklist...

In this review to the authors provide evidence-based definitions of organ failure in patients with acute decompensation of cirrhosis, describe the prevalence and prognostic impact of organ failure in these patients, and highlight current knowledge of the mechanisms responsible for its development. Excessive inflammatory response and a reduction of the capacity of organs to respond adequately to stress may sensitize cirrhotic patients to inflammation-driven organ damage and failure. The dynamic evolution of organ failure during early intensive management may provide a useful tool for guiding subsequent management strategies, or in some cases, for defining the futility of care...

BACKGROUND: The prevailing obstetric practice of planned cesarean delivery for triplet gestations is largely empiric and data on the optimal route of delivery are limited. OBJECTIVE: The primary objectives of this study are to determine the likelihood of success in an attempted vaginal delivery and assess maternal and neonatal outcomes of attempted vaginal vs planned cesarean delivery of triplets using a multiinstitution obstetric cohort. STUDY DESIGN: We performed a retrospective cohort study using data from the Consortium on Safe Labor, identifying triplet pregnancies with delivery at a gestational age ≥28 weeks...
