Abstract

BackgroundTranscatheter edge-to-edge mitral valve repair (TMVr) improves symptoms and survival for patients with heart failure with reduced left ventricular ejection fraction (HFrEF) and severe secondary mitral regurgitation despite guideline-recommended medical therapy (GRMT). Whether TMVr is cost-effective from a UK National Health Service (NHS) perspective is unknown.MethodsWe used patient-level data from the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) trial to perform a cost-effectiveness analysis of TMVr +GRMT versus GRMT alone from an NHS perspective. Costs for the TMVr procedure were based on standard English tariffs and device costs. Subsequent costs were estimated based on data acquired during the trial. Health utilities were estimated using the Short-Form 6-Dimension Health Survey.ResultsCosts for the index procedural hospitalisation were £18 781, of which £16 218 were for the TMVr device. Over 2-year follow-up, TMVr reduced subsequent costs compared with GRMT (£10 944 vs £14 932, p=0.006), driven mainly by reductions in heart failure hospitalisations; nonetheless, total 2-year costs remained higher with TMVr (£29 165 vs £14 932, pConclusionsFor patients with HFrEF and severe secondary mitral regurgitation similar to those enrolled in COAPT, TMVr increases life expectancy and quality-adjusted life expectancy compared with GRMT at an ICER that represents good value from an NHS perspective.

Abstract

Li4SiO4 and Li2TiO3 have long been recognized as two excellent promising tritium breeding materials. In this paper, two kinds of ceramic pebbles, Li4SiO4 pure phase ceramic pebbles and Li4SiO4-xLi2TiO3 multiphase ceramic pebbles were prepared by a melt spraying method at a superheating temperature of 100 ℃ and then tested for their performance. The proportion of pebbles with a particle diameter of 0.8∼1.2 mm reached the maximum of 24.02 % when the spraying pressure is 0.04 MPa. The surface of the pebbles prepared by the spraying method was smooth, and the surface roughness was reported for the first time to reach 2.039 μm. The sphericity reached 1.027. When the Ti/Si molar ratio was 0.5, the crush load of the pebbles after heat treatment reached 71.6 N and the thermal conductivity of the materials reached its maximum of 3.098 W/(m·K) at 700 ℃.

Abstract

This study proposed a new ethanol-lactic type fermentation (ELTF) and explored the optimal control strategy. Using batch experiments, the effects of pH, temperature and organic loading (OL) on ELTF were investigated. The sum of ethanol and lactic acid yield was highest at whole-control pH value of 4.0, 35°C temperature and OL of 33 gCOD/L. To improve ELTF, the dynamic pH control in the long-term CSTR was adjusted at 4.0 (1-28 days), 5.0 (29-44 days) and 4.0 (46-62 days) successively. The high concentration of ethanol and lactic acid was 8190.5 mg/L at 16th day of pH 4.0. At pH of 5.0, the average acidogenesis rate and total concentration of fermentation products increased 111.0% and 128.0%, respectively. Organisms of Lactobacillus and Bifidobacterium were the predominant bacteria in reactor. It can achieve the directional regulation of ELTF and provides parameter support for the application of two-phase anaerobic digestion.
