This single-center retrospective study included a total of 99 extracorporeal life support (ECLS) cannulated patients assigned to a traumatic extracorporeal life-support cohort (TECLS) or a non-traumatic extracorporeal life-support cohort (NTECLS). Forty-nine TECLS patients and 50 NTECLS patients were compared. The TECLS patients were significantly younger [49.9 years 16.6-86.2 vs. 57.1 (21.4-78.6); p = 0.007] and had lower body mass indices (BMIs) [27.7 kg/m(2) (20-37) vs. 32.5 (19-88.5); p = 0.001] than the NTECLS patients...

We previously experienced severe clot formation in a polyester-polymer alloy (PEPA) dialyzer and hemodialysis (HD) circuit with nafamostat mesilate (NM) as an anticoagulant. The possibility of NM adsorption to the PEPA membrane was taken into consideration, but there was not enough information. In the present study, we evaluated differences in the adsorption of NM between a PEPA membrane (FDX-120 GW, Nikkiso, Tokyo, Japan) and two different polysulfone membranes (FX-140, Fresenius Medical Care, Tokyo, Japan; NV-15U, Toray Medical, Tokyo, Japan)...

In this study, we analyzed the internal electric field E and specific absorption rate (SAR) of human biological tissues surrounding an air-core coil transcutaneous energy transmission transformer. Using an electromagnetic simulator, we created a model of human biological tissues consisting of a dry skin, wet skin, fat, muscle, and cortical bone. A primary coil was placed on the surface of the skin, and a secondary coil was located subcutaneously inside the body. The E and SAR values for the model representing a 34-year-old male subject were analyzed using electrical frequencies of 0...

Blood purification therapy using hemofilters with high adsorbing capabilities has been reported to remove excessive humoral mediators from the blood of patients with sepsis. However, there are insufficient studies of the adsorbates bound to hemofilter membranes. We hypothesized that these adsorbates in acute kidney injury (AKI) patients with sepsis were different from those in patients without sepsis and that proteome analysis of the adsorbates would identify novel substances of sepsis. This study included 20 patients who had AKI upon admission to intensive care units (ICUs) and who received continuous renal replacement therapy using polymethyl methacrylate hemofilters...

Current guidelines recommend adenosine diphosphate receptor inhibitors (ADPRi) be discontinued 5-7 days prior to cardiac surgery due to increased bleeding events, rates of re-exploration, and transfusions. However, the risks of left ventricular assist device (LVAD) implantation in patients taking an ADPRi have not previously been studied. We retrospectively identified 134 eligible patients with ischemic cardiomyopathy that underwent LVAD implantation between July 2009 and August 2013. The cohorts received an ADPRi ≤5 days of surgery (n = 25) versus >5 days prior or not at all (n = 109)...

A long-term durability test was conducted on a newly developed axial-flow ventricular assist device (VAD) with hydrodynamic bearings. The mock circulatory loop consisted of a diaphragm pump with a mechanical heart valve, a reservoir, a compliance tank, a resistance valve, and flow paths made of polymer or titanium. The VAD was installed behind the diaphragm pump. The blood analog fluid was a saline solution with added glycerin at a temperature of 37 °C. A pulsatile flow was introduced into the VAD over a range of flow rates to realize a positive flow rate and a positive pressure head at a given impeller rotational speed, yielding a flow rate of 5 L/min and a pressure of 100 mmHg...

Aortic insufficiency (AI) is a significant complication of long-term support of continuous flow left ventricular assist device (CF-LVAD) for patients with end-stage heart failure. A 26-year-old female with osteogenesis imperfecta (OI) was diagnosed with dilated phase hypertrophic cardiomyopathy (d-HCM)) and was implanted with Jarvik 2000, for bridge to transplantation. AI gradually developed and surgical intervention was indicated. We performed central aortic valve closure (CAVC) instead of valve replacement 20 months after CF-LVAD implantation...

Exhaustion of superficial veins coupled with the presence of intrathoracic central venous occlusions remains a significant obstacle for hemodialysis access creation; complex arteriovenous graft (AVG) configurations have been described. The axillary-iliac AVG was first reported in 1987, and few authors have explored this access. We evaluated our experience with this AVG configuration utilizing the early cannulation (EC) graft Flixene™ (Atrium ™, Hudson, NH, USA). Eight patients (75 % men; mean age 37 ± 10 years) with End-Stage Renal Disease (ESRD) underwent axillo-iliac AVG creation with Flixene™ grafts; all had exhausted peripheral veins, occluded thoracic central veins, and inadequate femoral veins...

Our aim was to conduct a scoping review of the regulations for hemodialyzers in the safety evaluation in Japan and the United States, and to evaluate the criteria for premarketing clinical trials and postmarketing safety reports to inform the development of a sophisticated premarketing evaluation in Japan. Regulations for approval of hemodialyzers were identified from the databases of the Ministry of Health, Labor and Welfare in Japan and the Federal Drug Agency (FDA) in the United States (US). The criteria for premarket clinical trials and postmarketing safety reports were evaluated for both countries...

This clinical study aimed to compare a novel and conventional artificial pancreas (AP) used in surgical patients for perioperative glycemic control, with respect to usability, blood glucose measurements, and glycemic control characteristics. From July in 2010 to March in 2015, 177 patients underwent perioperative glycemic control using a novel AP. Among them, 166 patients were eligible for inclusion in this study. Intensive insulin therapy (IIT) targeting a blood glucose range of 80-110 mg/dL was implemented in 82 patients (49 %), and the remaining 84 patients (51 %) received a less-intensive regime of insulin therapy...

The incidence of diabetes is increasing at an unprecedented pace and has become a serious health concern worldwide during the last two decades. Despite this, adequate glycemic control using an artificial pancreas has not been established, although the 21st century has seen rapid developments in this area. Herein, we review current topics in glycemic control for both the wearable artificial pancreas for type 1 and type 2 diabetic patients and the bedside artificial pancreas for surgical diabetic patients. In type 1 diabetic patients, nocturnal hypoglycemia associated with insulin therapy remains a serious problem that could be addressed by the recent development of a wearable artificial pancreas...

Human endothelial cells are used in experimental models for studying in vitro pathophysiological mechanisms of different diseases. We developed an original bioreactor, which can simulate human blood vessel, with capillary polysulfone membranes covered with the human umbilical vein endothelial cells (HUVECs) and we characterized its properties. The elaborated cell seeding and culturing procedures ensured formation of a confluent cell monolayer on the inside surface of capillaries within 24 h of culturing under the shear stress of 6...

Human mercaptoalbumin (HMA) is a reduced form of albumin that is associated with cardiovascular disease in dialysis patients. Albumin-leaky hemodialysis (HD) is increasingly recognized as a gold standard therapy because it is correlated with better prognosis compared to conventional HD. However, albumin-leaky HD induces low serum albumin concentration because of albumin leakage, which is a classical risk factor for mortality. The aim of this study was to explain the preferable prognosis in patients undergoing albumin-leaky HD with low serum albumin concentration...

Fulminant myocarditis is a rare but fatal serious disease that may cause prolonged native cardiac dysfunction with multiorgan failure despite temporary mechanical circulatory support with percutaneous venoatrial extracorporeal membrane oxygenation (VA-ECMO) or intraaortic balloon pumping (IABP). A 26-year-old man with fulminant myocarditis developed life-threatening multiorgan failure after 8 days support by VA-ECMO and IABP. He was transferred to our institution with prolonged cardiac dysfunction on hospital day 8; massive pulmonary edema developed into severe pulmonary dysfunction...

Recently, dialysis dose during hemodialysis treatment has been monitored by measuring the concentration of urea-like solutes such as uric acid in spent dialysate using near-ultraviolet (UV) light. The measured absorbance has been shown to have a good correlation with the time course of urea level even if the absorbance does not result from urea. However, the spent dialysate includes various solutes such as uric acid and albumin as well as unknown solutes that also absorb UV light. The effects of these solutes on monitored absorbance values are not clear...

Estimation of pressure and flow has been an important subject for developing implantable artificial hearts. To realize real-time viscosity-adjusted estimation of pressure head and pump flow for a total artificial heart, we propose the table estimation method with quasi-pulsatile modulation of rotary blood pump in which systolic high flow and diastolic low flow phased are generated. The table estimation method utilizes three kinds of tables: viscosity, pressure and flow tables. Viscosity is estimated from the characteristic that differential value in motor speed between systolic and diastolic phases varies depending on viscosity...

A 61-year-old man was implanted with a Jarvik 2000, a continuous axial flow type left ventricular assist device (LVAD), for end-stage heart failure due to dilated cardiomyopathy. One month later, his postoperative course was complicated with intractable oozing-type gastrointestinal bleeding from multiple small shallow ulcers and erosions in the colon. In addition, repeated bleeding episodes were encountered at around thoracentesis site for pleural effusion. Hematological examination showed that platelet counts and coagulation factors were kept within normal ranges...

The aggregability of red blood cell (RBCs) is associated with the contribution of plasma proteins, such as fibrinogen and lipoproteids, to blood-clotting. Hence, we hypothesized that RBC aggregability reflects the blood-clotting reaction. A noninvasive optical monitoring method to measure RBC aggregability for the assessment of blood-clotting stage during mechanical circulatory support was developed. An in vitro thrombogenic test was conducted with a rotary blood pump using heparinized fresh porcine blood. Near-infrared laser light at a wavelength of 785 nm was guided by an optical fiber...
