PURPOSE: Extracorporeal life support (ECLS) is a cardiopulmonary support system used for the treatment of severe cardiac and/or respiratory failure. Mortality is high partly because of the severity of the condition that requires support. The use of ECLS is generally associated with heavy sedation. The aim of this study was to demonstrate the feasibility of stopping sedation, allowing extubation of patients supported by ECLS. METHODS: 196 patients supported by ECLS for a period of 4 years were included...

PURPOSE: Influence of therapeutic thoracentesis on the pleural pressure (Pp) has been discussed in many clinical studies, however reasons of Pp changes are not precisely established. The aim of the study was to use a previously elaborated virtual cardiopulmonary patient (VP) in analysis of impact of physiological factors on Pp during the procedure. METHODS: Simulations were performed on VP with default values of parameters for which VP simulated the respiratory system of the average 50-year-old healthy Polish woman according to spirometric examination...

PURPOSE: Many novel materials have been developed such as composite resin, ceramic, zircon or metal-supported ceramic for use in aesthetic restoration of primary teeth and permanent teeth with extensive crown damage. The aim of the present study was to compare microtensile bond strengths on materials using the microtensile bond strength test. MATERIALS AND METHODS: The microtensile bond strength on the primary tooth dentin was measured on extracted primary teeth using an indirect method and fracture patterns were evaluated...

Masashi Tagaya, Saki Nagoshi, Morihiro Matsuda, Shunsuke Takahashi, Shinya Okano, Kazunobu Hara
PURPOSE: Currently, the foreign surfaces of various extracorporeal circulation devices are coated with a biocompatible polymer coating agent (BPA), which creates a hydrophilic blood-contacting layer to reduce thrombogenicity, while the membranes in hemodialyzers are not. We aimed to clarify other side effects of BPA-coated membranes by examining the diffusion performance in in vitro experiments. METHODS: We used a polyethersulfone membrane (sieving coefficient of albumin is ≤0...

PURPOSE: To assess LVAD complications and their overall effect on mortality and determine factors associated with development of early and long-term complications. METHODS: A retrospective cohort study of patients who underwent continuous flow LVAD placement between January 1, 2000 and November 30, 2013 was performed. The incidence of complications (sepsis or bacteremia, driveline infections, gastrointestinal bleeding, pump thrombosis, cerebrovascular accidents and anemia requiring transfusion) was collected and logistic regression and Cox proportional hazards analyses were performed...

A fully implantable axial left ventricular assist device LAP31 was developed for Chinese or other heart failure patients who need partial support. Based on the 5-Lpm total cardiac blood output of Chinese without heart failure disease, the design point of LAP31 was set to a flow rate of 3 Lpm with 100-mmHg pressure head. To achieve the required pressure head and good hemolytic performance, a structure that includes a spindly rotor hub and a diffuser with splitter and cantilevered main blades was developed. Computational fluid dynamics (CFD) was used to analyze the hydraulic and hemodynamic performance of LAP31...

BACKGROUND: Continuous flow left ventricular assistance devices (CF-LVADs) have revolutionized the treatment of advanced heart failure. Pump replacement for thrombosis is a high-risk procedure with a high perioperative mortality rate with possible recurrence. We aim to summarize our experience using a conservative approach with medical therapy. METHODS: We retrospectively reviewed records of patients who experienced pump thrombosis after LVAD implantation with HeartWare HVAD at our institution, from November 2010 to March 2016...

INTRODUCTION: In times of organ shortage, death while on the heart waiting-list still represents a major problem. As a consequence, bridging to transplant as well as the decision when to escalate therapy play a very important role. METHODS AND RESULTS: We report on two young patients with dilated cardiomyopathy and acute decompensation who were successfully bridged to heart transplantation with both left and temporary right ventricular assist devices in just 2 months...

BACKGROUND: We assessed the Th17 (T-helper cell)/Treg (Regulatory T cell) imbalance in sepsis patients with multiple organ dysfunction syndrome (MODS) and the clinical benefits of continuous high-volume hemofiltration (HVHF). METHODS: 48 sepsis patients, including 22 patients with MODS (MODS group, n = 22) and 26 without (non-MODS group, n = 26), and 20 healthy volunteer controls were enrolled. The patients in MODS group were randomly divided into the continuous blood purification (CBP) group (n = 11) receiving conventional comprehensive treatment plus high-volume hemofiltration and the non-CBP group (n = 11) receiving conventional comprehensive treatment only...

BACKGROUND: Gastrointestinal bleeding (GIB) is a complication reported in patients post left ventricular assist device (LVAD) implantation that is associated with high mortality rates. Thalidomide is an anti-angiogenic compound that may offer a potential option for management of refractory LVAD-related GIB. METHODS: A single-center, retrospective review was conducted from January 2009 to October 2016 at a tertiary cardiology center. It included LVAD patients initiated on thalidomide for refractory GIB...

BACKGROUND: Total/ionized calcium ratio has been used as an indirect index of increased plasma citrate concentration during citrate anticoagulation. However, they were obtained without any adjustment of total calcium for albumin. Herein, we investigated whether the albumin-corrected total/ionized calcium ratio performed better than total/ionized calcium ratio. METHODS: 20 critically ill patients were treated with continuous venovenous hemofiltration (CVVH) using citrate anticoagulation...

BACKGROUND: Sequential peritoneal equilibration test (sPET) is based on the consecutive performance of the peritoneal equilibration test (PET, 4-hour, glucose 2.27%) and the mini-PET (1-hour, glucose 3.86%), and the estimation of peritoneal transport parameters with the 2-pore model. It enables the assessment of the functional transport barrier for fluid and small solutes. The objective of this study was to check whether the estimated model parameters can serve as better and earlier indicators of the changes in the peritoneal transport characteristics than directly measured transport indices that depend on several transport processes...

INTRODUCTION: The aim of this study was to evaluate and compare the calcium (Ca2+) and hydroxide (OH-) ion release of 4 artificially produced pulp capping materials (MTA, Biodentin, TheraCal LC, Calsimol) used for indirect pulp capping treatment. METHODS: In total, 70 freshly extracted human third molar teeth were used for the study. Cavities of extracted teeth were prepared by round burs. The remaining dentin thickness (1 ± 0.3 mm) tissue was measured by a micrometer and cone beam computerized tomography...
