This study demonstrates the effectiveness of using oleogels from high oleic sunflower oil (HOSO) and monoglycerides as solid fat replacers in a sweet bakery product. Firstly, a methodology to obtain oleogels with desired properties based on mathematical models able to describe relationships between process and product characteristics variables followed by multi-objective optimization was applied. Later, muffins were prepared with the optimized oleogels and their physicochemical and textural properties were compared with those of muffins formulated using a commercial margarine (Control) or only HOSO...

BACKGROUND: Many patients with tetralogy of Fallot (TOF) who underwent surgical correction of their congenital cardiac malformation during infancy develop right ventricular dysfunction and exercise intolerance in the long term. The right ventricle (RV) dilates due to the development of severe pulmonary regurgitation (and secondary tricuspid insufficiency). To reduce RV dilation and improve exercise tolerance pulmonary valve replacement (PVR) is the common therapeutic strategy. Whether concomitant tricuspid valve repair (TVR) is beneficial in these pure volume-overload conditions is still unknown...

BACKGROUND: Adult cardiac surgery with extracorporeal circulation is known to be associated with increased risk of blood transfusion leading to adverse outcomes. Procedures like retrograde autologous priming (RAP) may reduce these negative side effects. This randomized prospective study was initiated to assess whether RAP using specifically designed RAP bag (Terumo) has immediate effects on patient outcome. METHODS: One hundred eighteen adults undergoing elective CABG or elective aortic valve replacement were randomly assigned by a computer program into two groups: the RAP group (n = 54) in which the retrograde autologous priming was applied and the non-RAP (n = 64) group in which the same setting was used without the possibility to save priming volume...

Composite membranes with defective metal-organic frameworks (MOFs) connect the emerging fields of MOF topological modification, MOF-polymer interfacial engineering and composite material functionalization. Although defective MOFs can be fabricated via thermal or chemical treatment, the relationship between hierarchical MOF structure and their performance in a polymeric membrane matrix has so far not been investigated. Here we show how a modulator fumarate-based MIL-53(Al) microwave synthesis process results in defective MOFs...

Vascular disease is a major cause of death worldwide, and the growing need for replacement vessels is not fully met by autologous grafts or completely synthetic alternatives. Tissue engineering has emerged as a compelling strategy for the creation of blood vessels for reconstructive surgeries. One promising method to obtain a suitable vessel scaffold is decellularization of donor vascular tissue followed by recellularization with autologous cells. To prevent thrombosis of vascular grafts, a confluent and functional autologous endothelium is required, and researchers are still looking for the optimal cell source and recellularization procedure...

INTRODUCTION: The acute surgical treatment of infective endocarditis (IE) carries a high risk of postoperative mortality. Most complications are linked to uncontrolled sepsis and inflammatory processes. Cytokine haemoadsorption is an extracorporeal technique which has benefits reported in haemodynamic stability and inflammatory response. CASE REPORT: A 46-year-old male patient underwent emergency cardiac surgery due to progressive IE. Postcardiotomy cardiogenic shock associated with cardiac surgery required the implantation of venoarterial (VA)-ECMO...

Right ventricular (RV) end-diastolic volume measured by cardiovascular magnetic resonance imaging (CMR) is a criterion for pulmonary valve replacement in patients with tetralogy of Fallot (TOF). We sought to determine if the ratio of echocardiographic, short-axis RV-to-left ventricular (LV) end-diastolic areas (EDA) could be used to predict RV volume on CMR. We retrospectively reviewed the echocardiograms of all patients with repaired TOF who underwent CMR at our institution from 2011 to 2015 and also had an echocardiogram within 6 months of the CMR...

Sepsis-induced changes in pharmacokinetic parameters are a well-known problem in intensive care medicine. Dosing of antibiotics in this setting is therefore challenging. Alterations to the substance-specific kinetics of anti-infective substances have an effect on the distribution and excretion processes in the body. Increased clearance and an increased distribution volume (Vd ) and particularly compromized organ function with reduced antibiotic elimination are often encountered in patients with sepsis. Renal replacement treatment, which is frequently used in intensive care medicine, represents a substantial intervention in this system...

Rhabdomyolysis is characterized by muscle cell death which can result in acute kidney injury from pigment nephropathy. We present a patient who developed rhabdomyolysis immediately after deceased donor kidney transplantation surgery and was managed with continuous renal replacement therapy that resulted in successful salvage of the kidney allograft. Patients who develop acute kidney failure requiring renal replacement therapy generally have a poor prognosis. It is worth noting that while continuous veno-venous hemofiltration (CVVHF) offers greater volume support and continuous clearance compared to hemodialysis (HD), recent studies have demonstrated no clinically significant improvement in clinical outcome between the two...

BACKGROUND: Most of the literature on shoulder arthroplasty failure comes from high-volume centers. These reports tend to exclude the experience of community orthopedic surgeons, who perform most of the shoulder joint replacements. METHODS: We analyzed the failure reports mandated by the US Food and Drug Administration for all hospitals. Each reported event from 2012 to 2016 was characterized by implant, failure mode, and year of surgery. RESULTS: For the 1673 anatomic arthroplasties, the most common failure modes were glenoid component failure (20...

Transportable normothermic kidney perfusion for 24 hours or longer could enable viability assessment of marginal grafts, increased organ utilization and improved transplantation logistics. Eleven clinically-declined kidneys were perfused normothermically, six from donors after brain stem death (DBD, median cold ischemia time 33±36.9 hours) and five from donors after circulatory death (DCD, 36.2±38.3 hours): n=3 kidneys were perfused using Ringer's lactate to replace excreted urine volume, and n=8 using urine recirculation to maintain perfusate volume without fluid replenishment...

PURPOSE: We designed and evaluated a simple method for predicting the effects of intra-fractional and/or inter-fractional motion on dose distribution during carbon ion radiotherapy (CIRT) for solitary-lesion stage I lung cancer. METHODS: The proposed method uses computed tomography (CT) images from treatment planning and intra-tumoral and/or inter-tumoral displacement. The predicted dose distribution (PDD) was calculated by replacing the current tumor region with the stopping power ratio (SPR) of the lung, and replacing the moved tumor region with the SPR of the tumor...

Decellularized matrices offer a beneficial substitute for biomimetic scaffolds in tissue engineering. The current study examines the potential of decellularized placental vessel sleeves (PVS) as a periosteal protective sleeve to enhance bone regeneration in embryonic day 18 chick femurs contained within the PVS and cultured organotypically over a 10 day period. The femurs are inserted into decellularized biocompatibility-tested PVS and maintained in an organotypic culture for a period of 10 days. In femurs containing decellularized PVS, a significant increase in bone volume (p < 0...

Anthropogenic climate change, principally induced by the large volume of carbon dioxide emission from the global economy driven by fossil fuels, has been observed and scientifically proven as a major threat to civilization. Meanwhile, fossil fuel depletion has been identified as a future challenge. Lignocellulosic biomass in the form of organic residues appears to be the most promising option as renewable feedstock for the generation of energy and platform chemicals. As of today, relatively little bioenergy comes from lignocellulosic biomass as compared to feedstock such as starch and sugarcane, primarily due to high cost of production involving pretreatment steps required to fragment biomass components via disruption of the natural recalcitrant structure of these rigid polymers; low efficiency of enzymatic hydrolysis of refractory feedstock presents a major challenge...

OBJECTIVES: To describe the relationship between the extent of primary aortic repair and the incidence of reoperations after surgery for type A aortic dissection. METHODS: A retrospective cohort of 1159 patients treated for type A aortic dissection at eight Nordic low- to medium-sized cardiothoracic centers from 2005 to 2014. Data were gathered from patient records and national registries. Patients were separately divided into 3 groups according to the distal anastomoses technique (ascending aorta [n = 791], hemiarch [n = 247], and total arch [n = 66]), and into 2 groups for proximal repair (aortic root replacement [n = 285] and supracoronary repair [n = 832])...

BACKGROUND: In chronic hemodialysis patients with high risk of bleeding, optimal anticoagulation of the extracorporeal circuit is challenging. Heparin-free hemodialysis (HD) with heparin-coated AN69ST dialyzer is now considered as a good option and recommended by experts. Predilutional hemodiafiltration (HDF) may represent also a feasible alternative but has been poorly investigated. In this study, our aim was to evaluate the performance of on-line automated predilution heparin-free HDF as compared to conventional heparin-free HD with a heparin-coated membrane...
