Despite current standard of care, the average 5-year mortality after an initial diagnosis of heart failure (HF) is about 40%, reflecting an urgent need for new therapeutic approaches. Previous studies demonstrated that the epigenetic reader protein bromodomain-containing protein 4 (BRD4), an emerging therapeutic target in cancer, functions as a critical coactivator of pathologic gene transactivation during cardiomyocyte hypertrophy. However, the therapeutic relevance of these findings to human disease remained unknown...

BACKGROUND: Functional status (FS) before intensive care unit (ICU) admission is associated with short-term and long-term outcomes among critically ill patients. However, measures of FS are generally not integrated into ICU-specific mortality prediction models. METHODS: This retrospective cohort study used prospectively collected data from 9638 consecutive patients admitted to a single ICU between 1 October 2005 and 30 September 2015. For each ICU admission, FS was prospectively determined and classified into three discrete categories based on performance of basic daily living activities (FS1 - fully independent; FS2 - partly dependent; FS3 - completely dependent)...

The pathophysiology of delirium remains poorly understood. Low leptin level has been associated with features leading to delirium such as dysregulated immune functions and loss of neuroprotective effects. The purpose of the present study was to investigate the relationship between plasma leptin level at intensive care unit (ICU) entry and subsequent occurrence of delirium in critically ill patients. This single-center prospective cohort study in China allocated 336 critically ill patients admitted to ICU between 05/2015 and 05/2016 into a delirium group (n=102) and non-delirium group (n=234) based on whether delirium occurred during their stay at the ICU...

This prospective study aimed to assess the association between prior functional status and hospital mortality for patients admitted to four intensive care units in Spain between 2006 and 2012. Prior functional status was classified into three groups, using a modification of the Glasgow Outcome Scale (GOS), including group 1 with no limitations on activities of daily living; group 2 with some limitations but self-sufficient; and group 3 who were dependent on others for their activities of daily living. Of the 1,757 patients considered (mean Simplified Acute Physiology Score [SAPS] predicted mortality 14...

REVIEW
Craig Hutto, Mindy French
Dysnatremia is a common finding in the intensive care unit (ICU) and may be a predictor for mortality and poor clinical outcomes. Depending on the time of onset (ie, on admission vs later in the ICU stay), the incidence of dysnatremias in critically ill patients ranges from 6.9% to 15%, respectively. The symptoms of sodium derangement and their effect on brain physiology make early recognition and correction paramount in the neurologic ICU. Hyponatremia in brain injured patients can lead to life-threatening conditions such as seizures and may worsen cerebral edema and contribute to alterations in intracranial pressure...

Good clinical practice is based on a secure and accurate diagnosis. Poor nutrition is frequently associated with disorders of the liver, and a specific nutrition diagnosis is needed for providing best care and experiencing successful outcome. There is opportunity for better-structured approaches to making secure and consistent nutritional diagnoses in patients with liver disease. Nutrition is the set of integrated processes by which cells, tissues, organs and the whole body acquire the energy and nutrients to retain normal structure and perform the required functions...

BACKGROUND: Despite the central role of nurses in intensive care, a relationship between intensive care nurse workload/staffing ratios and survival has not been clearly established. We determined whether there is a threshold workload/staffing ratio above which the probability of hospital survival is reduced and then modeled the relationship between exposure to inadequate staffing at any stage of a patient's ICU stay and risk-adjusted hospital survival. METHODS: Retrospective analysis of prospectively collected data from a cohort of adult patients admitted to two multi-disciplinary Intensive Care Units was performed...

In vitro cultures provide a valuable tool in studies examining the survival, morphology and function of cells in the auditory system. Primary cultures of primary auditory neurons have most notably provided critical insights into the role of neurotrophins in cell survival and morphology. Functional studies have also utilized in vitro models to study neuronal physiology and the ion channels that dictate these patterns of activity. Here we examine what influence time-in-culture has on the activity of primary auditory neurons, and how this affects our interpretation of neurotrophin and antibiotic-mediated effects in this population...

In this paper, we develop a personalized real-time risk scoring algorithm that provides timely and granular assessments for the clinical acuity of ward patients based on their (temporal) lab tests and vital signs; the proposed risk scoring system ensures timely intensive care unit (ICU) admissions for clinically deteriorating patients. METHODS: The risk scoring system is based on the idea of sequential hypothesis testing under an uncertain time horizon. The system learns a set of latent patient subtypes from the offline electronic health record data, and trains a mixture of Gaussian Process (GP) experts, where each expert models the physiological data streams associated with a specific patient subtype...

With an eye on the sequence of two Indian papers concurrently published in Diabetes Therapy, this paper analyzes skin differences among races and points to a lack of organized structured education sessions as the main cause of the high prevalence of lipodystrophy (LD) and consequent poor metabolic control. Only half of all insulin-treated patients reach their therapeutic targets worldwide. The factors involved in this are manifold, including the choice of overlong and repeatedly reused needles, as well as a failure to systematically rotate injection sites, all of which lead to skin LD...

BACKGROUND: Standardized late preterm infant (LPI) discharge criteria ensure best practice and help guide the neonatal provider to determine the appropriate level of care following birth. However, the location can vary from the well newborn setting to the neonatal intensive care unit (NICU). PURPOSE: The purpose of this review is to examine differences in LPI discharge criteria between the well newborn setting and the NICU by answering the clinical questions, "What are the recommended discharge criteria for the LPI and do they differ if admitted to the well newborn setting versus the NICU?" SEARCH STRATEGY: Databases searched include CINAHL, TRIP, PubMed, and the Cochrane Library...

The increasing aging of the population in highly developed countries poses a profound impact on intensive care services. This is illustrated by a finding from a large Austrian database showing that 20% of all intensive care patients are aged ≥80 years. Age per se is not an exclusion criteria for admission to the intensive care unit, but older patients are frequently affected by multiple comorbidities and experience a decreased physiologic reserve. Due to the very heterogeneous population of aged patients and since no generally accepted criteria for admission and treatment of these patients exist, any treatment decision must be made taking into consideration the individual situation...

Importance: Latent cytomegalovirus (CMV) infection is present in more than half the adult population, and a viral reactivation (ie, when the virus becomes measurable in body fluids such as blood) can occur in up to one-third of these individuals during episodes of critical illness. Objective: To determine whether antiviral therapy is safe and effective for preventing CMV reactivation in a general population of critically ill patients. Design, Setting, and Participants: A single-center, open-label, randomized, controlled clinical trial recruited 124 CMV-seropositive patients undergoing mechanical ventilation for at least 24 hours in the intensive care unit between January 1, 2012, and January 31, 2014...
