Charge markups for health care are variable and inflated several times beyond cost. Using the 2015 Medicare Provider Fee-For-Service Utilization and Payment Data file, we identified providers who billed for critical care hours and related procedures, including CPR, EKG interpretation, central line placement, arterial line placement, chest tube/thoracentesis, and emergent endotracheal intubation. Markup ratios (MRs), defined as the amount charged divided by the amount allowable, were calculated and compared; 42...

BACKGROUND: Cardiogenic shock (CS) is the most life-threatening manifestation of acute heart failure. Its complexity and high in-hospital mortality may justify the need for invasive monitoring with a pulmonary artery catheter (PAC). METHODS: Patients with CS included in the CardShock Study, an observational, prospective, multicenter, European registry, were analyzed, aiming to describe the real-world use of PAC, evaluate its impact on 30-day mortality, and the ability of different hemodynamic parameters to predict outcomes...

BACKGROUND: The results of neonatal aortic arch surgery using cerebro-myocardial perfusion were analyzed. Selective cerebral and myocardial perfusion, using two separate pump rotors, was compared with standard, using a single pump rotor with an arterial line Y-connector. METHODS: Between 5/2008-5/2016, 69 consecutive neonates underwent arch repair using either selective cerebro-myocardial perfusion (Group A, n=34) or standard (Group B, n=35). The groups were similar for age, weight, BSA, prevalence of one-stage or staged repair and single ventricle palliation; male gender was more frequent in Group A...

AIMS/HYPOTHESIS: The macrophage-specific glycoprotein sCD163 has emerged as a biomarker of low grade inflammation in the metabolic syndrome and related disorders. High sCD163 levels are seen in acute sepsis as result of direct lipopolysaccharide-mediated shedding of the protein from macrophage surfaces including Kupffer cells. The aims of this study were to investigate if low grade endotoxinemia in human subjects results in increasing levels of sCD163 in a cortisol-dependent manner. METHODS: We studied eight male hypopituitary patients and eight age and gender matched healthy controls during intravenous low dose LPS or placebo infusion administered continuously over 360 min...

BACKGROUND: To date it has not been possible to obtain a comprehensive 3D assessment of fetal hemodynamics because of the technical challenges inherent in imaging small cardiac structures, movement of the fetus during data acquisition, and the difficulty of fusing data from multiple cardiac cycles when a cardiac gating signal is absent. Here we propose the combination of volumetric velocity-sensitive cardiovascular magnetic resonance imaging ("4D flow" CMR) and a specialized animal preparation (catheters to monitor fetal heart rate, anesthesia to immobilize mother and fetus) to examine fetal sheep cardiac hemodynamics in utero...

BACKGROUND: Vascular access devices are widely used in healthcare settings worldwide. The insertion of a vascular access device creates a wound, vulnerable to irritation, injury and infection. Vascular access-associated skin complications are frequently reported in the literature, however very little evidence is available regarding the incidence and risk factors of these conditions to inform practice and technology development. OBJECTIVES: To estimate the incidence of vascular access-associated skin complications, and to identify patient, catheter and healthcare-related characteristics associated with skin complication development...

Brain inflammation is associated with various types of neurodegenerative diseases, including Alzheimer's disease. Quantifying inflammation with PET is a challenging and invasive procedure, especially in frail patients, because it requires blood sampling from an arterial catheter. A widely used alternative to arterial sampling is a supervised clustering algorithm (SVCA), which identifies the voxels with minimal specific binding in the PET images, thus extracting a reference region for noninvasive kinetic modeling...

OBJECTIVES: To characterize renin in critically ill patients. Renin is fundamental to circulatory homeostasis and could be a useful marker of tissue-perfusion. However, diurnal variation, continuous renal replacement therapy and drug-interference could confound its use in critical care practice. DESIGN: Prospective observational study. SETTING: Single-center, mixed medical-surgical ICU in Europe. PATIENTS: Patients over 18 years old with a baseline estimated glomerular filtration rate greater than 30 mL/min/1...

The accurate quantification of cardiac output (CO) is given vital importance in modern medical practice, especially in high-risk surgical and critically ill patients. CO monitoring together with perioperative protocols to guide intravenous fluid therapy and inotropic support with the aim of improving CO and oxygen delivery has shown to improve perioperative outcomes in high-risk surgical patients. Understanding of the underlying principles of CO measuring devices helps in knowing the limitations of their use and allows more effective and safer utilization...

BACKGROUND: The distending intravascular pressure at no flow conditions reflects the stressed volume. While this haemodynamic variable is recognised as clinically important, there is a paucity of reports of its range and responsiveness to volume expansion in patients without cardiovascular disease and no reports of correlations to echocardiographic assessments of left ventricular filling. METHODS: Twenty-seven awake (13 male), spontaneously breathing patients without any history of cardiopulmonary, vascular or renal disease were studied prior to induction of anaesthesia...

BACKGROUND: Persistent pulmonary hypertension of the newborn (PPHN) is due to a failure of pulmonary vascular relaxation. Vasopressin, a systemic vasoconstrictor acting on smooth muscle AVPR1a receptors, is used in treatment of PPHN. We sought to determine acute effects of vasopressin infusion on pulmonary hemodynamics in a large animal model of hypoxic PPHN. METHODS: PPHN was induced in 6 newborn piglets by 72 h normobaric hypoxia (FiO2 = 0.10); controls were 7 age-matched 3-day-old piglets...

BACKGROUND: Indirect blood pressure measurements are often used to guide clinical decisions, but few studies have verified their agreement with direct arterial blood pressure in nonhuman primates. Here, the accuracy and precision of Doppler (DOP) and oscillometric (OS) [systolic (OSsys), mean (OSmean), and diastolic (OSdias)] blood pressure readings were assessed in rhesus macaques. METHODS: DOP and OS were utilized to measure blood pressure values in nine anesthetized rhesus macaques, which were compared to direct measurements via a saphenous arterial catheter...
