In this study, visible light (VL) was adopted for permanganate (PM) activation without additional catalyst, where sulfamethazine (SMT) was selected as the probe compound. Experiment results showed that the VL/PM system can effectively degrade SMT through pseudo-first-order reaction kinetics. Influencing factors including PM dosage, solution pH, humid acid (HA) and coexisting anions (CO32-, SO42-, Cl- and NO3-) which affect SMT photo-degradation were also examined. Pyrophosphate (PP) had an inhibitory effect on SMT degradation due to the complexation of PP with Mn (III). Electron spin resonance (ESR) spectrometry and UV-Vis spectrophotometer proved that VL can activate PM to generate ·O2- and Mn (III) reactive species. Furthermore, based on the active site prediction, intermediates identification and Density Functional Theory (DFT) calculation, two main degradation pathways involving SMT molecular rearrangement and cleavage of S-N bond were proposed. Moreover, the energy barriers of the two degradation pathways were also calculated. This study offers a novel approach for aqueous SMT removal and deepens our understanding of the degradation mechanism of SMT through DFT calculation, which hopes to shed light on the future development of VL/PM treatment.Imaging methods for hyperpolarized (HP) 13C agents must sample the evolution of signal from multiple agents with distinct chemical shifts within a very brief timeframe (typically less then 1 min), which is challenging using conventional imaging methods. In this work, we compare two of the most commonly used HP spectroscopic imaging methods, spectral-spatial selective excitation and multi-echo chemical shift encoding (CSE, also referred to as IDEAL), for a typical preclinical HP [1-13C]pyruvate imaging scan at 7 T. Both spectroscopic encoding techniques were implemented and validated in HP experiments imaging enzyme phantoms and the murine kidney. SNR performance of these two spectroscopic imaging approaches was compared in numerical simulations and phantom experiments using a single-shot flyback EPI readout for spatial encoding. With identical effective excitation angles, the SNR of images acquired with spectral-spatial excitations and CSE were found to be effectively equivalent.
To compare the atherosclerosis disease burden between ankylosing spondylitis (AS) and non-radiographic (nr) axial spondyloarthritis (axSpA) and establish a model that allows to identify high-cardiovascular (CV) risk in axial spondyloarthritis patients.

Cross-sectional study from the AtheSpAin cohort, a Spanish multicenter cohort aimed to study atherosclerosis in axSpA. Carotid ultrasound (US) was performed to determine the carotid intima-media wall thickness (cIMT) and detect the presence of carotid plaques. The European cardiovascular disease risk assessment model, the Systematic COronary Risk Evaluation (SCORE), was also applied.

A set of 639 patients with AS and 167 patients with nr-axSpA without history of CV events were recruited. AS patients were older showing more CV risk factors and higher values of C reactive protein and erythrocyte sedimentation rate (ESR) than those with nr-axSpA. However, no difference in the prevalence of carotid plaques or in the cIMT was found between both groups in the aa clinically relevant proportion of them can be detected by applying a model containing age, BASFI and ESR.
To compare the efficacy and safety of TCZ in monotherapy (TCZ
) vs. combined with conventional immunosuppressive drugs (TCZ
) in Giant Cell Arteritis (GCA) in a clinical practice scenario.

Multicenter study of 134 patients with refractory GCA. Patients on TCZ
(n=82) were compared with those on TCZ
(n=52). Drugs were methotrexate (MTX) (n=48), azathioprine (n=3), and leflunomide (n=1). The main outcomes were prolonged remission (normalization of clinical and laboratory parameters for at least 6 months) and the number of relapses.

Patients on TCZ
were younger (68.8±8.0vs 71.2±9.0 years; p=0.04), with a trend to a longer GCA duration (median [IQR],18.5 [6.25-34.0] vs. Novobiocin in vitro 13.0 [7.75-33.5] months; p=0.333), higher C-reactive protein (CRP) levels (2.1[1-4.7] vs 1.2 [0.2-2.4] mg/dL; p=0.003), and more prevalence of extra-cranial large-vessel vasculitis (LVV) (57% vs. 34.1%; p=0.007). In both groups, rapid and sustained improvement was observed. Despite the longer GCA duration, and the higher CRP levels and prevalence of LVV in the TCZ
, the improvement was similar in both groups at 12 months. Moreover, in the TCZ
group, prolonged remission was significantly higher at 12-month. Relapses and serious adverse events were similar in both groups.

In clinical practice, TCZ in monotherapy or combined with conventional immunosuppressive agents is effective and safe in patients with GCA. Nevertheless, the addition of immunosuppressive drugs, usually MTX, seems to allow a higher rate of prolonged remission, even in patients with a longer GCA duration, more extra-cranial LVV involvement, and higher acute-phase reactants.

Acute Kidney Injury (AKI), induced by Checkpoint Inhibitors therapies (CPI-induced AKI), is an uncommon but severe Immune-Related Adverse Event (IRAE). The aim was to describe the epidemiology, risks factors, clinical, and laboratory characteristics of these renal adverse events (AEs) in a real-life cohort treatment.

Consecutive patients undergoing a checkpoint inhibitor (CPI) therapy at the Hôpital Lyon Sud from January 2015 to July 2017 were included. A systematic retrospective analysis of medical files was performed, monthly serum creatinine levels, associated treatments, and occurrence of other IRAEs data were collected. AKI episodes explained by classic AKI aetiologies (prerenal, obstructive, septic) were excluded from the analysis.

CPI-induced AKI incidence was 3.7% (13/352)and appeared to be time-dependent (7.7% (11/143) for patients with >3months of CPI exposure), ranging from 1 to 16months. All cases with available histology were acute tubulointerstitial nephritis (ATIN), with poor urinary sediment.
