Our ability to rationalise the activity of heterogeneous catalytic materials relies on a precise understanding of both the structure and composition of the catalyst under reaction conditions to resolve active sites. Their highly dynamic nature means that catalysis suffers from an observer effect, where the act of measuring activity and/or structure will modify the structure itself. Herein, we present a well-defined catalyst consisting of 2 nm Pt nanoparticles supported on SiO2 that can be dynamically modified and regenerated without irreversibly changing the underlying structure or activity of the catalyst. Using in situ diffuse reflectance infrared Fourier transform spectroscopy and transmission electron microscopy we identify that the catalyst is resistant to oxidative and reductive treatments, but irreversibly restructures in reactive environments (CO + O2) at moderate pressures and temperatures. We show that by using transient pressure pulse experiments it is possible to minimise the restructuring in reactive environments, which when coupled with kinetic modelling can be used to identify site and state dependent activity while simultaneously quantifying the number of active sites. The well-defined nature of this 2 nm Pt/SiO2 catalyst means it can be utilised to gain molecular insight into catalytic processes and act as a new material for use in heterogeneous catalytic surface science. Further, the rapid restructuring of the catalyst during CO oxidation demonstrates that it is not a benign characterisation tool for comparison of catalysts. [ABSTRACT FROM AUTHOR]

Police presence on social media has become increasingly common in recent years and has arguably altered policing in many ways. Although research in this area is increasing, the growing presence of police on a range of social media platforms requires further examination of the various nuances that continue to emerge regarding this symbiosis. To that end, only a small number of studies have examined this topic from the perspective of police personnel in the Canadian context. Accordingly, drawing on in-depth interviews with police personnel overseeing police social media sites, this article examines how Canadian police services manage negativity and conflict online. The findings suggest that police services address negativity and conflict on their social media sites by drawing on the principles of procedural justice to guide their interactions. We discuss the implications of these findings and how police–public social media interactions might be improved. [ABSTRACT FROM AUTHOR]

This study introduces a novel iterative Bragg peak removal with automatic intensity correction (IBR-AIC) methodology for X-ray absorption spectroscopy (XAS), specifically addressing the challenge of Bragg peak interference in the analysis of crystalline materials. The approach integrates experimental adjustments and sophisticated post-processing, including an iterative algorithm for robust calculation of the scaling factor of the absorption coefficients and efficient elimination of the Bragg peaks, a common obstacle in accurately interpreting XAS data, particularly in crystalline samples. The method was thoroughly evaluated on dilute catalysts and thin films, with fluorescence mode and large-angle rotation. The results underscore the technique's effectiveness, adaptability and substantial potential in improving the precision of XAS data analysis. While demonstrating significant promise, the method does have limitations related to signal-to-noise ratio sensitivity and the necessity for meticulous angle selection during experimentation. Overall, IBR-AIC represents a significant advancement in XAS, offering a pragmatic solution to Bragg peak contamination challenges, thereby expanding the applications of XAS in understanding complex materials under diverse experimental conditions.

A detailed knowledge of reaction kinetics is key to the development of new more efficient heterogeneous catalytic processes. However, the ability to resolve site dependent kinetics has been largely limited to surface science experiments on model systems. Herein, we can bypass the pressure, materials, and temperature gaps, resolving and quantifying two distinct pathways for CO oxidation over SiO2-supported 2 nm Pt nanoparticles using transient pressure pulse experiments. We find that the pathway distribution directly correlates with the distribution of well-coordinated (e.g., terrace) and under-coordinated (e.g., edge, vertex) CO adsorption sites on the 2 nm Pt nanoparticles as measured by in situ DRIFTS. We conclude that well-coordinated sites follow classic Langmuir-Hinshelwood kinetics, but under-coordinated sites follow non-standard kinetics with CO oxidation being barrierless but conversely also slow. This fundamental method of kinetic site deconvolution is broadly applicable to other catalytic systems, affording bridging of the complexity gap in heterogeneous catalysis.Kim and co-workers introduce a new ‘kinetic site deconvolution’ method to identify active sites on heterogeneous catalysts by linking reaction rates to specific adsorption environments.

Aims: In VICTORIA, vericiguat compared with placebo reduced the risk of cardiovascular death (CVD) and heart failure hospitalization (HFH) in patients enrolled after a worsening heart failure (WHF) event. We examined clinical outcomes and efficacy of vericiguat as it relates to background use of loop diuretics in patients with WHF. Methods and results: We calculated the total daily loop diuretic dose equivalent to furosemide dosing at randomization and categorized these as: no loop diuretic, 1–39, 41–80, 40, and >80 mg total daily dose (TDD). The primary composite outcome of CVD/HFH and its components were evaluated based on TDD loop diuretic and expressed as adjusted hazard ratios with 95% confidence intervals. Post‐randomization rates of change in TDD were also examined. Of 4974 patients (98% of the trial) with diuretic dose information available at randomization, 540 (10.8%) were on no loop diuretic, 647 (13.0%) were on 1–39, 1633 (32.8%) were on 40, 1185 (23.8%) were on 41–80, and 969 (19.4%) were on >80 mg TDD. Patients with higher TDD had a higher rate of primary and secondary clinical outcomes. There were no significant interactions with TDD at randomization and efficacy of vericiguat versus placebo for any outcome (all pinteraction > 0.5). Post‐randomization diuretic dose changes for vericiguat and placebo showed similar rates of up‐titration (19.6 and 20.2/100 person‐years), down‐titration (16.8 and 18.1/100 person‐years), and stopping diuretics (22.9 and 24.2/100 person‐years). Conclusions: Loop diuretic TDD at randomization was independently associated with worse outcomes in this high‐risk population. The efficacy of vericiguat was consistent across the range of diuretic doses. [ABSTRACT FROM AUTHOR]

Juveniles contribute to crime in natural resource-based boom communities, but there has been very little research examining the extent of their involvement. To respond to this gap in the literature, two indicators of youth arrests and court referrals in North Dakota—the state hardest hit by the 2000s oil boom—were examined. Although arrest rates for North Dakota youth were more than two times higher than the national average in 2019, almost three-quarters of them were for minor offenses. In addition, arrest and court referral rates in oil-producing counties were lower than those for non oil-producing counties. When controlling for demographic and economic factors, and county-specific fixed effects in panel analyses from 2011 to 2019, oil production is negatively associated with youth arrest rates, but positively associated with juvenile court referrals. However, oil-producing counties had very strong county-specific fixed effects which on average raised youth arrest and court referral rates. Arrest rates were also positively associated with unemployment rates while median household income was negatively associated with Group B offenses and juvenile court referrals. Implications for future research into the boom-crime relationship are discussed in light of these findings. [ABSTRACT FROM AUTHOR]

Aim: To investigate the effects of Cimlanod, a nitroxyl donor with vasodilator properties, on water and salt excretion after an administration of an intravenos bolus of furosemide. Methods and results: In this randomized, double‐blind, mechanistic, crossover trial, 21 patients with left ventricular ejection fraction <45%, increased plasma concentrations of N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) and receiving loop diuretics were given, on separate study days, either an 8 h intravenous (IV) infusion of cimlanod (12 μg/kg/min) or placebo. Furosemide was given as a 40 mg IV bolus four hours after the start of infusion. The primary endpoint was urine volume in the 4 h after the bolus of furosemide during infusion of cimlanod compared with placebo. Median NT‐proBNP at baseline was 1487 (interquartile range: 847–2665) ng/L. Infusion of cimlanod increased cardiac output and reduced blood pressure without affecting cardiac power index consistent with its vasodilator effects. Urine volume in the 4 h post‐furosemide was lower with cimlanod (1032 ± 393 ml) versus placebo (1481 ± 560 ml) (p = 0.002), as were total sodium excretion (p = 0.004), fractional sodium excretion (p = 0.016), systolic blood pressure (p < 0.001), estimated glomerular filtration rate (p = 0.012), and haemoglobin (p = 0.010), an index of plasma volume expansion. Conclusions: For patients with heart failure and congestion, vasodilatation with agents such as cimlanod reduces the response to diuretic agents, which may offset any benefit from acute reductions in cardiac preload and afterload.

Aims Methods and results Conclusions Reverse ventricular remodelling, defined as a decrease in left ventricular end‐systolic volume indexed to body surface area (LVESVI) or an increase in left ventricular ejection fraction (LVEF), is associated with improved clinical outcomes in patients with heart failure with reduced ejection fraction (HFrEF). However, the underlying pathophysiological mechanisms remain unclear.We evaluated paired core‐lab assessed echocardiograms and measurements of 92 biomarkers at baseline and 8 months thereafter in 419 participants with HFrEF. Reverse ventricular remodelling was defined as a >5% LVEF increase or >15% LVESVI relative decrease between baseline and 8 months. We evaluated the association between baseline biomarkers and their changes with reverse ventricular remodelling in the prospectively randomized controlled VICTORIA (Vericiguat Global Study in Subjects With Heart Failure With Reduced Ejection Fraction) trial. Of 419 patients (median age 66 [interquartile range 57–74] years, 27.4% women), 206 (49.2%) had reverse ventricular remodelling (either a 5% LVEF increase or a 15% LVESVI decrease). There were no differences in baseline biomarker concentrations between patients with versus those without reverse ventricular remodelling on follow‐up. However, in patients with reverse ventricular remodelling there were significant decreases in biomarkers relating to inflammation and cardiac metabolism; particularly the tumour necrosis factor superfamily member 13B (ratio 0.82, 95% confidence interval [CI] 0.77–0.88), growth differentiation factor‐15 (ratio 0.74, 95% CI 0.66–0.84), and insulin‐like growth factor binding protein 7 (ratio 0.80, 95% CI 0.73–0.88).Reverse ventricular remodelling in patients with HFrEF is associated with a decrease of biomarkers related to inflammation and cardiac metabolism.

Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous syndrome that may emerge from overlapping systemic processes associated with comorbidities. We assessed whether unique clusters of circulating proteins are associated with specific clinical characteristics and functional status at baseline and follow-up in a well-phenotyped cohort of patients with HFpEF., Methods: We evaluated 368 proteins associated with cardiovascular disease and inflammation in prerandomization blood samples from 763 VITALITY-HFpEF (Vericiguat to Improve Physical Functioning in Daily Living Activities of Patients With HFpEF) participants who had a left ventricular ejection fraction ≥45% and a heart failure decompensation event within 6 months. Proteins were clustered, and their associations with clinical characteristics, baseline, and 24-week functional outcomes (Kansas City Cardiomyopathy Questionnaire Physical Limitation Score, 6-minute walk distance [6MWD], and Fried frailty phenotype) were estimated with linear regression. Elastic net regression was used to derive a proteomic summary composite to predict changes in 24-week functional outcomes., Results: Four unique protein clusters were identified, containing 24, 66, 197, and 81 proteins. At baseline, 2 protein clusters with the hub proteins caspase-3 and Dickkopf-related protein 1 were associated with increased frailty, whereas the cluster with tumor necrosis factor receptor 1 as a hub protein was associated with lower Kansas City Cardiomyopathy Questionnaire Physical Limitation Score and shorter 6MWD. By contrast, the cluster with protein C as a hub protein was associated with less frailty and longer a 6MWD. The 24-week increase in 6MWD was negatively correlated with the protein cluster with caspase-3; the protein C cluster was correlated with less frailty at 24 weeks. The baseline proteomic summary composite predicted observed changes in Kansas City Cardiomyopathy Questionnaire Physical Limitation Score and 6MWD at 24 weeks (r=0.42 and 0.30; P <0.001 for both)., Conclusions: Proteomics differentiate specific baseline functional traits associated with HFpEF and may facilitate phenotyping in a heterogeneous disease. These proteins also provide insights into the diverse pathophysiology of HFpEF and which patients may improve functional status during follow-up., Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03547583.

Background and Aims: In the VICTORIA trial of participants with heart failure (HF) and reduced ejection fraction, vericiguat (V) reduced the primary composite outcome [time to first HF hospitalization (HFH) or cardiovascular death (CVD)] (897 events) compared to placebo (P) (972 events) (hazard ratio, 0.90; 95% confidence interval [CI], 0.82-0.98; p=0.02). In this prespecified secondary analysis, we applied the weighted composite endpoint (WCE) and the win ratio (WR) methods to provide complementary assessments of treatment effect., Methods and Results: The WCE method estimated the mean HFH-adjusted survival based on prespecified weights from a Delphi panel of the VICTORIA executive committee and national leaders: mild (weight per event: 0.39), moderate (0.5) or severe (0.67) HFH, and CVD (1.0). The unmatched WR was estimated for the descending hierarchy of CVD, then recurrent HFH. The WCE used all 3412 primary clinical events: 875(V:416/P:459) severe HFH, 1614(767/847) moderate HFH and 68(38/30) mild HFH, 855(414/441) CVD. Improved HFH-adjusted survival occurred with vericiguat [mean 78.2% vs. 75.6%; difference (95% CI): 2.4% (1.7%-3.2%); p<0.0001]. Based on the comparison of 6,375,624 pairs, the WR of 1.13 (95% CI, 1.03-1.24, p=0.01) also indicated improved clinical outcomes with vericiguat., Conclusions: The results of the WCE and WR methods were consistent with the primary analysis of the time to first HFH or CVD. Whereas both WCE and WR assessed recurrent events, the WCE allowed inclusion of all recurrent events, insights on the severity of HFH events, and an absolute measure of the participant-treatment experience.

Background: Optimal medical therapy (OMT) scoring may stratify clinical risk in real-world chronic heart failure with reduced ejection fraction (HFrEF) by integrating use and dosing of guideline-directed medical therapy (GDMT) for HFrEF., Objectives: The purpose of this study was to characterize patients and associated long-term clinical outcomes by OMT score-derived treatment groups., Methods: CHAMP-HF (Change the Management of Patients with Heart Failure) included U.S. outpatients with chronic HFrEF receiving ≥1 GDMT. OMT subgroups were defined as suboptimal (score <3), acceptable (score = 3), and optimal (score ≥4) by baseline use and dose of GDMT, as proposed by the HF Collaboratory consortium. Cox proportional hazard analyses were used to assess for all-cause and cardiovascular death across subgroups, after adjusting for demographic and clinical covariates., Results: The authors studied 4,582 participants enrolled in CHAMP-HF with available 2-year follow-up. Median age was 68 years, 1,327 (29%) were women, and 2,842 (62%) were White, non-Hispanic. Median OMT score across the population was 4 (Q1-Q3: 2-5), and 1,628 (35%) had suboptimal, 665 (14%) had acceptable, and 2,289 (50%) had optimal therapy. Participants with optimal treatment were younger, had higher annual household income, and were enrolled from practices with dedicated HF clinics (all P < 0.001) than participants with acceptable or suboptimal treatment. Participants with optimal treatment had lower all-cause death (adjusted HR: 0.77; 95% CI: 0.64-0.92) and cardiovascular death (adjusted HR: 0.79; 95% CI: 0.65-0.96) than those with suboptimal treatment., Conclusions: Across a large cohort of chronic ambulatory HFrEF, OMT scores stratified risk of all-cause and cardiovascular death., Competing Interests: Funding Support and Author Disclosures CHAMP-HF was supported by Novartis Pharmaceuticals.

Over the past decade, the field of heart failure (HF) has witnessed remarkable progress in drug development, resulting in the approval of numerous groundbreaking drugs by the U.S. Food and Drug Administration. To address some of these challenges, the U.S. Food and Drug Administration has issued guidance documents that have been critical in contemporary HF drug development; however, there are still many challenges in need of investigation. This article leverages efforts of the Heart Failure Collaboratory and the scientific community to discuss the critical need for innovative trial designs, important concepts in clinical trials in the modern era, and the utilization of big data to accelerate HF drug development. At this inflection point in HF drug development, it is imperative that, as a global scientific community, we foster increased collaboration among researchers, clinicians, patients, and regulatory bodies. Only through such unified efforts can we navigate the complexities of HF, accelerate the development process, and ultimately deliver effective therapies that transform patient outcomes., Competing Interests: Funding Support and Author Disclosures Dr Januzzi has a board position with Imbria Pharma; has received grant support from Abbott, Applied Therapeutics, AstraZeneca, BMS, and Novartis Pharmaceuticals; has received consulting income from Abbott Diagnostics, Beckman-Coulter, Jana Care, Janssen, Novartis, Prevencio, Quidel, and Roche Diagnostics; and has served on clinical endpoint committees/data safety monitoring boards for Abbott, AbbVie, Amgen, CVRx, Medtronic, Pfizer, and Roche Diagnostics.
