Abstract
Abstract
Background
The PARADISE-MI trial examined the efficacy of sacubitril/valsartan in patients with acute myocardial infarction (AMI) complicated by reduced left ventricular ejection fraction (LVEF), pulmonary congestion or both. Little is known about the trajectory and echocardiographic correlates of pulmonary congestion in this population.
Purpose
We sought to assess the trajectory of pulmonary congestion using lung ultrasound (LUS) and its association with cardiac structure and function in a subset of patients enrolled in PARADISE- MI.
Methods
Participants underwent 8-zone LUS at baseline and 8 months. B-lines were quantified offline, blinded to treatment group, clinical findings, timepoint and outcomes by a core laboratory. Paired t-tests, chi-squared tests, and linear regression analyses were conducted.
Results
Among 152 patients (median age 65 years, 32% women, 35% obese, mean LVEF 41%), any B-lines were detectable in 87%, the median sum of B-lines in 8 zones was 4 [IQR 2–8], and 67% had ≥3 B-lines indicative of congestion. Greater number of B-lines at baseline was associated with larger left atrial (LA) size, higher E/e' and E/A ratios, greater degree of mitral regurgitation, worse right ventricular (RV) systolic function, and higher tricuspid regurgitation velocity (P trend <0.05 for all) (Figure 1). Among 115 patients with 8-month LUS data, there was a significant decline in number of B-lines from baseline (mean ± SD: −1.6±7.3; p=0.018). Adjusted for baseline, B-lines at follow-up were on average 6 (95% CI: 3, 9) higher in a patient who experienced an intercurrent heart failure (HF) event than a non-HF patient (p=0.001). Among 75 patients with ≥3 B-lines at baseline, a decrease in B-lines to <3, indicating decongestion, occurred in 37% and was similar in the sacubitril/valsartan and ramipril groups (36% vs. 39%, p=0.83).
Conclusions
In this post-AMI cohort, sonographic B-lines, indicating pulmonary congestion, were common at baseline and were significantly higher at follow-up in those who developed HF. Worse pulmonary congestion at baseline was associated with prognostically important echocardiographic markers of LV filling pressure, pulmonary pressure, and RV function.

Abstract
This work reports on the ion transport properties and defect chemistry in anhydrous lithium thiocyanate Li(SCN), which is a pseudo-halide Li+ cation conductor. An extensive doping study was conducted, employing magnesium, zinc and cobalt thiocyanate as donor dopants to systematically vary the conductivity and derive a defect model. The investigations are based on impedance measurements and supported by other analytical techniques such as X-ray powder diffraction (XRPD), infrared (IR) spectroscopy, and density functional theory (DFT) calculations. The material was identified as Schottky disordered with lithium vacancies being the majority mobile charge carriers. In the case of Mg2+ as dopant, defect association with lithium vacancies was observed at low temperatures. Despite a comparably low Schottky defect formation enthalpy of (0.6 ± 0.3) eV, the unexpectedly high lithium vacancy migration enthalpy of (0.89 ± 0.08) eV distinguishes Li(SCN) from the chemically related lithium halides. A detailed defect model of Li(SCN) is presented and respective thermodynamic and kinetic data are given. The thiocyanate anion (SCN)- has a significant impact on ion mobility due to its anisotropic structure and bifunctionality in forming both Li-N and Li-S bonds. More details about the impact on ion dynamics at local and global scale, and on the defect chemical analysis of the premelting regime at high temperatures are given in separate publications (Part II and Part III).

Abstract
Carbonyl reductase (CBR) is an enzyme involved in protection from oxidative stress. In rainbow trout (Oncorhynchus mykiss), the hepatic mRNA abundance of the two isoforms (A and B) is increased after exposure to treated sewage effluents, as well as after exposure with β-naphthoflavone (β-NF) and the pro-oxidant paraquat. In this study, we show that the same chemicals similarly increase the single known hepatic CBR mRNA level and CBR catalytic activity in the coastal living eelpout (Zoarces viviparus). Hepatic CBR mRNA abundance and catalytic activity were also compared between eelpout collected at contaminated and reference sites on the Swedish west coast, but no differences were observed. In conclusion, CBR is a potential biomarker candidate for monitoring the exposure and effects of AhR agonists and/or pro-oxidants in the marine environment, but more research is needed to investigate temporal regulation as well as dose dependency for different chemicals. The mRNA and enzymatic assays presented in this study provide two additional tools for researchers interested in expanding their biomarker battery.
