The usefulness of a new indirect calorimeter in critically ill adult patients.

Background & Aims: The use of indirect calorimetry to determine energy requirements is highly recommended in critically ill patients. To facilitate this a new and easy to use calorimeter (Q-NRG+, Cosmed) was developed. The primary aim of our study was to describe the usefulness of this calorimeter and, secondarily, to investigate the agreement between measured and predicted energy needs in a large cohort of critically ill adult patients.

Association between fat-free mass and survival in critically ill patients with COVID-19: A prospective cohort study.

Background: Most critically ill patients with COVID-19 experience malnutrition and weight loss associated with negative clinical outcomes. Our primary aim was to assess body composition during acute and late phase of illness in these patients in relation to clinical outcome and secondary to tailored nutrition support.

Methods: This prospective cohort study included adult critically ill patients with COVID-19.

Posaconazole for prevention of invasive pulmonary aspergillosis in critically ill influenza patients (POSA-FLU): a randomised, open-label, proof-of-concept trial.

Purpose: Influenza-associated pulmonary aspergillosis (IAPA) is a frequent complication in critically ill influenza patients, associated with significant mortality. We investigated whether antifungal prophylaxis reduces the incidence of IAPA.

Methods: We compared 7 days of intravenous posaconazole (POS) prophylaxis with no prophylaxis (standard-of-care only, SOC) in a randomised, open-label, proof-of-concept trial in patients admitted to an intensive care unit (ICU) with respiratory failure due to influenza (ClinicalTrials.

Energy expenditure and feeding practices and tolerance during the acute and late phase of critically ill COVID-19 patients.

Background & Aims: Different metabolic phases can be distinguished in critical illness, which influences nutritional treatment. Achieving optimal nutritional treatment during these phases in critically ill patients is challenging. COVID-19 patients seem particularly difficult to feed due to gastrointestinal problems.

Relation between intra-abdominal pressure and early intestinal ischemia in rats.

Background: Little is known on early irreversible effects of increased intra-abdominal pressure (IAP). Therefore, timing of abdominal decompression among patients with abdominal compartment syndrome remains challenging. The study objective was to determine the relation between IAP and respiratory parameters, hemodynamic parameters, and early intestinal ischemia.

Intestinal fatty acid binding protein as a predictor for intra-abdominal pressure-related complications in patients admitted to the intensive care unit; a prospective cohort study (I-Fabulous study).

Purpose: Critically ill patients are at risk for intra-abdominal hypertension (IAH) and related complications such as organ failure, abdominal compartment syndrome (ACS), and death. This study aimed to determine the value of urinary and serum intestinal fatty acid binding protein (I-FABP) levels as early marker for IAH-associated complications.

Methods: A prospective observational study was conducted in two academic institutional mixed medical-surgical ICUs in the Netherlands.

Successful Reduction of Creatine Kinase and Myoglobin Levels in Severe Rhabdomyolysis Using Extracorporeal Blood Purification (CytoSorb®).

Rhabdomyolysis, if severe, can lead to acute kidney injury (AKI). Myoglobin is an iron and oxygen-binding protein that is freely filtered by the glomerulus. Precipitation of myoglobin in the nephrons' distal parts is responsible for tubular damage with AKI as a consequence.

Tool inhibitors and assays to interrogate the biology of the TRAF2 and NCK interacting kinase.

The TRAF2 and NCK interacting kinase (TNIK) has been proposed to play a role in cytoskeletal organization and synaptic plasticity and has been linked, among others, to neurological disorders. However, target validation efforts for TNIK have been hampered by the limited kinase selectivity of small molecule probes and possible functional compensation in mouse models. Both issues are at least in part due to its close homology to the kinases MINK1 (or MAP4K6) and MAP4K4 (or HGK).

Voriconazole Resistance and Mortality in Invasive Aspergillosis: A Multicenter Retrospective Cohort Study.

Background: Triazole resistance is an increasing problem in invasive aspergillosis (IA). Small case series show mortality rates of 50%-100% in patients infected with a triazole-resistant Aspergillus fumigatus, but a direct comparison with triazole-susceptible IA is lacking.

Methods: A 5-year retrospective cohort study (2011-2015) was conducted to compare mortality in patients with voriconazole-susceptible and voriconazole-resistant IA.

In-hospital cardiovascular events after liver transplantation: predictors and long-term outcome.

Introduction: Liver transplantation has emerged as a successful therapy for end-stage liver disease. However, cardiovascular mortality is the leading cause of fatality in the postoperative period. The aim of this study was to reveal the prevalence and identify risk factors of early cardiovascular events (CVEs).

Identification of a Chrysanthemic Ester as an Apolipoprotein E Inducer in Astrocytes.

The apolipoprotein E (APOE) gene is the most highly associated susceptibility locus for late onset Alzheimer's Disease (AD), and augmenting the beneficial physiological functions of apoE is a proposed therapeutic strategy. In a high throughput phenotypic screen for small molecules that enhance apoE secretion from human CCF-STTG1 astrocytoma cells, we show the chrysanthemic ester 82879 robustly increases expressed apoE up to 9.4-fold and secreted apoE up to 6-fold and is associated with increased total cholesterol in conditioned media.

Intestinal fatty acid binding protein as a marker for intra-abdominal pressure-related complications in patients admitted to the intensive care unit; study protocol for a prospective cohort study (I-Fabulous study).

Background: Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) have detrimental effects on all organ systems and are associated with increased morbidity and mortality in critically ill patients admitted to an intensive care unit. Intra-bladder measurement of the intra-abdominal pressure (IAP) is currently the gold standard. However, IAH is not always indicative of intestinal ischemia, which is an early and rapidly developing complication.

Immature granulocytes predict microbial infection and its adverse sequelae in the intensive care unit.

Background: We evaluated the predictive value of immature granulocyte (IG) percentage in comparison with white blood cell counts (WBC) and C-reactive protein (CRP), for infection, its invasiveness, and severity in critically ill patients.

Methods: In 46 consecutive patients, blood samples were collected at the day (0) of a clinical suspicion of microbial infection and at days 1 and 3 thereafter. We defined infections, bloodstream infection, and septic shock within 7 days after enrollment.

What to do when a competent ICU patient does not want to live anymore but is dependent on life-sustaining treatment? Experience from The Netherlands.

If patients on the intensive care unit (ICU) are awake and life-sustaining treatment is suspended because of the patients' request, because of recovering from the disease, or because independence from organ function supportive or replacement therapy outside the ICU can no longer be achieved, these patients can suffer before they inevitably die. In The Netherlands, two scenarios are possible for these patients: (1) deep palliative (terminal) sedation through ongoing administration of barbiturates or benzodiazepines before withdrawal of treatment, or (2) deliberate termination of life (euthanasia) before termination of treatment. In this article we describe two awake patients who asked for withdrawal of life-sustaining measures, but who were dependent on mechanical ventilation.

Noninvasive functional liver blood flow measurement: comparison between bolus dose and steady-state clearance of sorbitol in a small-rodent model.

Plasma clearance of D-sorbitol, a nontoxic polyol, occurs predominantly in the liver and has been used to measure functional liver blood flow after bolus and steady- state intravenous administration. However, it is not known which of these two administration methods is superior. Therefore, plasma D-sorbitol clearance was studied in an animal model both after a bolus dose and under steady-state (SS) conditions and compared directly with liver blood flow, under normal conditions, and after the induction of endotoxin (LPS) sepsis.

Severe group A streptococcal toxic shock syndrome presenting as primary peritonitis: a case report and brief review of the literature.

Streptococcal toxic shock syndrome (STSS) can be defined as a septic shock syndrome resulting from infection with toxin-producing group A streptococci (GAS). STSS can sporadically present as primary peritonitis in previously healthy persons. Signs of STSS are non-specific and patients generally present with flu-like symptoms and can develop a life-threatening toxic shock syndrome in just a few hours.

The effect of rosiglitazone on asymmetric dimethylarginine (ADMA) in critically ill patients.

Asymmetric dimethylarginine (ADMA) plays a crucial role in the arginine-nitric oxide pathway. Critically ill patients have elevated levels of ADMA which proved to be a strong and independent risk factor for ICU mortality. The aim of this study was to investigate the effect of the peroxisome proliferator-activated receptor (PPAR)-gamma agonist rosiglitazone on ADMA plasma levels in critically ill patients.

"Flatus profuse present in the muscles": subcutaneous emphysema of the lower abdominal wall and thighs, described in 1593 by fabricius hildanus.

Background: Between 1598 and 1641, 600 medical and surgical observations made by the famous German surgeon Guilhelmius Fabricius Hildanus (1560-1634) were published in his Observationum et curationum chirurgicarum centuriae I-VI.

Methods: Review of the extant document for evidence of infection-related cases.

Results: One of the case reports, published as Observatio LXX in the fifth Centuria, bears the title (in translation) Of flatus, profuse present in the muscles.
