Physics - Accelerator Physics - Abstract
The number of cells in a $\pi$-mode standing wave (SW) accelerating structure for the Compact linear Collider (CLIC) project is limited by mode overlap with nearby modes. The distributed coupling scheme avoids mode overlap by treating each cell as independent. Designs of cells suitable for distributed coupling with strong wakefield damping have not previously been studied. In this paper we develop a SW cell to be used in a distributed coupling structure that can satisfy the CLIC transverse wakepotential limit. From the middle cell of the CLIC-G* travelling wave (TW) structure, a SW cell is designed. The cell is adapted to be suitable for distributed coupling. Its wakepotentials in an ideal case of open boundaries are reduced to satisfy the wakepotential threshold. An electric boundary is added to the model to simulate total reflection at the distribution network. A horizontal coupler cell that connects to the distribution network such that the reflected wakefields remain similar to the open boundary case is simulated. A triplet module which takes advantage of cell-to-cell coupling to reduce reflected wakepotential is presented., Comment: 6 pages, 11 figures

With the advent of high cadence, all-sky automated surveys, supernovae (SNe) are now discovered closer than ever to their dates of explosion. However, young pre-maximum light follow-up spectra of Type Ic supernovae (SNe Ic), probably arising from the most stripped massive stars, remain rare despite their importance. In this paper we present a set of 49 optical spectra observed with the Las Cumbres Observatory through the Global Supernova Project for 6 SNe Ic, including a total of 17 pre-maximum spectra, of which 8 are observed more than a week before V-band maximum light. This dataset increases the total number of publicly available pre-maximum light SN Ic spectra by 25% and we provide publicly available SNID templates that will significantly aid in the fast identification of young SNe Ic in the future. We present detailed analysis of these spectra, including Fe II 5169 velocity measurements, O I 7774 line strengths, and continuum shapes. We compare our results to published samples of stripped supernovae in the literature and find one SN in our sample that stands out. SN 2019ewu has a unique combination of features for a SN Ic: an extremely blue continuum, high absorption velocities, a P-cygni shaped feature almost 2 weeks before maximum light that TARDIS radiative transfer modeling attributes to C II rather than H$\alpha$, and weak or non-existent O I 7774 absorption feature until maximum light., Comment: Submitted to the Astrophysical Journal. 15 pages, 6 figures

Medicine - Abstract
Introduction First steps for knee osteoarthritis (OA) is a cluster randomised implementation trial examining the effect of an educational reminder message included in knee X-ray reports on the proportion of people subsequently referred to exercise professionals for their knee OA. Evaluating the processes supporting the completion of the study and the efficacy of the reminder message is essential to interpreting the outcomes of the study and aiding translation into practice.Methods and analysis We will conduct a concurrent process evaluation throughout the current study using a previously published framework for examining cluster randomised trials. This framework divides processes into those occurring at the cluster level and those at the target population level. For the current study, the cluster level is within radiology clinics. The target population is people with newly diagnosed radiologically evident, structural knee OA. A mixed methods design, incorporating survey data, administrative records, field notes and semi-structured interviews with representatives from radiology clinics and people with knee OA, will evaluate these processes. The focus of the evaluation will be recruitment and response processes of the radiology clinics and delivery and response processes for the people with knee OA. We will also describe the context and explore how the nudge theory of behavioural change influences the outcome of the study.Ethics and dissemination The study protocol, inclusive of the process evaluation, was approved by Macquarie University Human Research Ethics Committee (#520221190343842). Findings will be disseminated through national and international conferences, national industry stakeholders and patient advocacy groups to reach all levels of healthcare. Staff at radiology clinics and people with knee OA involved in interviews provide written, informed consent to participate in the process evaluation. Specific findings will be incorporated into training modules aimed at radiology clinics and will be developed by our industry partners.Trial registration Prospectively registered with the Australian New Zealand Clinical Trials Registry (ACTRN12622001414707p). Registration occurred in December 2022

Summary: Background: Genetic variants in COL4A1 and COL4A2 (encoding collagen IV alpha chain 1/2) occur in genetic and sporadic forms of cerebral small vessel disease (CSVD), a leading cause of stroke, dementia and intracerebral haemorrhage (ICH). However, the molecular mechanisms of CSVD with ICH and COL4A1/COL4A2 variants remain obscure. Methods: Vascular function and molecular investigations in mice with a Col4a1 missense mutation and heterozygous Col4a2 knock-out mice were combined with analysis of human brain endothelial cells harboring COL4A1/COL4A2 mutations, and brain tissue of patients with sporadic CSVD with ICH. Findings: Col4a1 missense mutations cause early-onset CSVD independent of hypertension, with enhanced vasodilation of small arteries due to endothelial dysfunction, vascular wall thickening and reduced stiffness. Mechanistically, the early-onset dysregulated endothelium-dependent hyperpolarization (EDH) is due to reduced collagen IV levels with elevated activity and levels of endothelial Ca2+-sensitive K+ channels. This results in vasodilation via the Na/K pump in vascular smooth muscle cells. Our data support this endothelial dysfunction preceding development of CSVD-associated ICH is due to increased cytoplasmic Ca2+ levels in endothelial cells. Moreover, cerebral blood vessels of patients with sporadic CSVD show genotype-dependent mechanisms with wall thickening and lower collagen IV levels in those harboring common non-coding COL4A1/COL4A2 risk alleles. Interpretation: COL4A1/COL4A2 variants act in genetic and sporadic CSVD with ICH via dysregulated EDH, and altered vascular wall thickness and biomechanics due to lower collagen IV levels and/or mutant collagen IV secretion. These data highlight EDH and collagen IV levels as potential treatment targets. Funding: MRC, Wellcome Trust, BHF.

Determining soil nitrogen (N) availability is essential in agriculture to minimise over-application, maximise growers’ returns and reduce potential environmental consequences. The present study assesses soil mineral N (nitrate-N and ammonium-N) using the diffusive gradients in thin-films (DGT) technique against the conventional potassium chloride (KCl) extraction. The DGT technique has demonstrated reliable predictability for plant-available P, Cu and Zn. However, the use of DGT to quantify soil N bioavailability is underreported and N measurements made with DGT have not been compared to plant growth responses or N uptake. A pot trial using wheat was performed to determine the suitability of the DGT technique to predict N plant uptake and plant biomass. Four contrasting soil types from South Australia were used, and four rates of N were applied to the soil. DGT devices and KCl extraction were used at sowing to measure soil mineral N. These data were then compared with plant relative yield (YR) and N uptake after harvesting the plants. Soil mineral N, as measured by both the DGT and KCl extraction techniques, demonstrated a significant positive correlation with YR, with an R2 value of 0.6; however, DGT-N extracted comparatively more nitrate (NO3–, >87 % of CN) than KCl-N (65 % of EN). Mineral N and NO3– extracted by both DGT and KCl significantly correlated with plant N uptake albeit this correlation was stronger for KCl (R2 = 0.8) than DGT (R2 = 0.6). The same parameters also positively and significantly correlated with YR, however in this case, both correlations were similar and only modest (R2

Background Renal cell carcinoma is the most common type of kidney cancer, comprising approximately 85% of all renal malignancies. Patients with advanced renal cell carcinoma are the focus of this National Institute for Health and Care Excellence multiple technology appraisal. A patient’s risk of disease progression depends on a number of prognostic risk factors; patients are categorised as having intermediate/poor risk or favourable risk of disease progression. Objectives The objectives of this multiple technology appraisal were to appraise the clinical effectiveness and cost-effectiveness of lenvatinib plus pembrolizumab versus relevant comparators listed in the final scope issued by the National Institute for Health and Care Excellence: sunitinib, pazopanib, tivozanib, cabozantinib and nivolumab plus ipilimumab. Methods The assessment group carried out clinical and economic systematic reviews and assessed the clinical and cost-effectiveness evidence submitted by Eisai, Hatfield, Hertfordshire, UK (the manufacturer of lenvatinib) and Merck Sharp & Dohme, Whitehouse Station, NJ, USA (the manufacturer of pembrolizumab). The assessment group carried out fixed-effects network meta-analyses using a Bayesian framework to generate evidence for clinical effectiveness. As convergence issues occurred due to sparse data, random-effects network meta-analysis results were unusable. The assessment group did not develop a de novo economic model, but instead modified the partitioned survival model provided by Merck Sharp & Dohme. Results The assessment group clinical systematic review identified one relevant randomised controlled trial (CLEAR trial). The CLEAR trial is a good-quality, phase III, multicentre, open-label trial that provided evidence for the efficacy and safety of lenvatinib plus pembrolizumab compared with sunitinib. The assessment group progression-free survival network meta-analysis results for all three risk groups should not be used to infer any statistically significant difference (or lack of statistically significant difference) for any of the treatment comparisons owing to within-trial proportional hazards violations or uncertainty regarding the validity of the proportional hazards assumption. The assessment group overall survival network meta-analysis results for the intermediate-/poor-risk subgroup suggested that there was a numerical, but not statistically significant, improvement in the overall survival for patients treated with lenvatinib plus pembrolizumab compared with patients treated with cabozantinib or nivolumab plus ipilimumab. Because of within-trial proportional hazards violations or uncertainty regarding the validity of the proportional hazards assumption, the assessment group overall survival network meta-analysis results for the favourable-risk subgroup and the all-risk population should not be used to infer any statistically significant difference (or lack of statistically significant difference) for any of the treatment comparisons. Only one cost-effectiveness study was included in the assessment group review of cost-effectiveness evidence. The study was limited to the all-risk population, undertaken from the perspective of the US healthcare system and included comparators that are not recommended by the National Institute for Health and Care Excellence for patients with untreated advanced renal cell carcinoma. Therefore, the extent to which resource use and results are generalisable to the NHS is unclear. The assessment group cost-effectiveness results from the modified partitioned survival model focused on the intermediate-/poor-risk and favourable-risk subgroups. The assessment group cost-effectiveness results, generated using list prices for all drugs, showed that, for all comparisons in the favourable-risk subgroup, treatment with lenvatinib plus pembrolizumab costs more and generated fewer benefits than all other treatments available to NHS patients. For the intermediate-/poor-risk subgroup, treatment with lenvatinib plus pembrolizumab costs more and generated more benefits than treatment with cabozantinib and nivolumab plus ipilimumab. Conclusions Good-quality clinical effectiveness evidence for the comparison of lenvatinib plus pembrolizumab with sunitinib is available from the CLEAR trial. For most of the assessment group Bayesian hazard ratio network meta-analysis comparisons, it is difficult to reach conclusions due to within-trial proportional hazards violations or uncertainty regarding the validity of the proportional hazards assumption. However, the data (clinical effectiveness and cost-effectiveness) used to populate the economic model are relevant to NHS clinical practice and can be used to inform National Institute for Health and Care Excellence decision-making. The assessment group cost-effectiveness results, generated using list prices for all drugs, show that lenvatinib plus pembrolizumab is less cost-effective than all other treatment options.

Several drug treatment options are available for NHS patients with advanced or metastatic disease, and the choice of treatment varies depending on a patient’s risk of disease progression. A new drug combination, lenvatinib plus pembrolizumab, may soon become available to treat NHS patients. This review explored whether treatment with lenvatinib plus pembrolizumab offered value for money to the NHS. What did we do? We reviewed the effectiveness of treatment with lenvatinib plus pembrolizumab versus other NHS treatment options. We also estimated the costs and benefits of treatment with lenvatinib plus pembrolizumab versus current NHS treatments for patients with higher and lower risks of disease progression. What did we find? Compared with current NHS treatments, treatment with lenvatinib plus pembrolizumab may increase the time that people with a higher risk of disease progression (i.e. worsening disease) were alive. However, for patients with a lower risk of disease progression, the available evidence is limited and only shows that treatment with lenvatinib plus pembrolizumab may prolong the time that patients have a stable level of disease. For all patients, compared to all current NHS treatments, treatment with lenvatinib plus pembrolizumab is very expensive. What does this mean? Compared with current NHS treatments for untreated renal cell carcinoma, using published prices (which do not include any discounts that are offered to the NHS), treatment with lenvatinib plus pembrolizumab may not provide good value for money to the NHS. Scientific summary Background Renal cell carcinoma (RCC) is the most common type of kidney cancer, comprising approximately 85% of all renal malignancies. Patients with advanced RCC (aRCC) have Stage 3 (locally advanced) or Stage 4 (metastatic) disease. A patient’s risk of disease progression depends on a number of prognostic risk factors. The International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) model is used in NHS clinical practice to categorise patients into one of two groups, namely favourable risk or intermediate/poor risk. This systematic review and cost-effectiveness analysis has been conducted to inform the following National Institute for Health and Care Excellence (NICE) multiple technology appraisal: lenvatinib with pembrolizumab for untreated aRCC (ID3760). In November 2021, the Medicines and Healthcare products Regulatory Agency approved the use of lenvatinib plus pembrolizumab as a treatment for all patients with untreated aRCC. Objectives The comparators listed in the final scope issued by NICE differ depending on the risk of disease progression. The objectives of this assessment were to appraise the clinical effectiveness and cost-effectiveness of lenvatinib plus pembrolizumab versus: cabozantinib and nivolumab plus ipilimumab in the intermediate-/poor-risk subgroup sunitinib, pazopanib and tivozanib in the favourable-risk subgroup sunitinib, pazopanib and tivozanib in the all-risk population. Clinical and economic systematic review methods The assessment group (AG) carried out a systematic review of clinical effectiveness evidence following the general principles outlined by the Centre for Reviews and Dissemination (CRD). The review was reported using the criteria recommended in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Searches were conducted between 11 October 2021 and 22 November 2021 in accordance with the general principles recommended by the European Network for Health Technology Assessment. The protocol is registered with PROSPERO (registration number: CRD42021285879). The AG reviewed only randomised controlled trials (RCTs) and full economic analyses identified by the searches. However, the group also considered evidence provided by the manufacturers of lenvatinib (Eisai Ltd) and pembrolizumab (Merck Sharp & Dohme, Whitehouse Station, NJ, USA) provided in submissions to NICE; company submission (CS) reference lists were searched for relevant RCTs. In line with the final scope issued by NICE, the outcomes considered by the AG were overall survival (OS), progression-free survival (PFS), objective tumour response rate, adverse events (AEs), health-related quality of life (HRQoL), incremental cost per life-year gained and incremental cost per quality-adjusted life-year (QALY) gained. Clinical effectiveness results Direct clinical effectiveness evidence (CLEAR trial) The AG systematic review included one RCT, the CLEAR trial. The CLEAR trial was a good-quality, phase III, multicentre, open-label RCT (with an ongoing extension phase) that provided evidence for the comparison of the efficacy of lenvatinib plus pembrolizumab versus sunitinib. Results for all outcomes were assessed at the third interim analysis (August 2020, median OS follow-up of 26.6 months), that is the final data cut-off for PFS. The companies also presented OS results from an updated OS analysis (March 2021, median OS follow-up of approximately 33 months). At the time of the third interim analysis, the CLEAR trial hazard ratio (HR) results showed statistically significant improvements in PFS and objective tumour response rate for patients treated with lenvatinib plus pembrolizumab versus patients treated with sunitinib for the intermediate-/poor-risk subgroup, the favourable-risk subgroup and the all-risk population. The HR results from the updated OS analysis showed a statistically significant improvement for patients treated with lenvatinib plus pembrolizumab versus patients treated with sunitinib for the intermediate-/poor-risk subgroup and the all-risk population; there were too few events in the favourable-risk subgroup for robust OS conclusions to be drawn. Eisai carried out a treatment-switching analysis to test whether adjusting for the effect of subsequent treatments affected OS results. Results were generated only for the all-risk population and were marked as academic-in-confidence. Nearly all the patients in the CLEAR trial lenvatinib plus pembrolizumab and sunitinib arms experienced at least one all-grade AE, with more Grade ≥ 3 AEs reported in the lenvatinib plus pembrolizumab arm than in the sunitinib arm. The proportion of patients who discontinued treatment of either lenvatinib or pembrolizumab due to AEs was approximately twice as high as patients who discontinued treatment of sunitinib; the proportion of patients who withdrew treatment of both lenvatinib and pembrolizumab due to AEs was approximately the same as the proportion of patients who withdrew treatment with sunitinib. Health-related quality of life was measured using three tools, including the EuroQol-5 Dimensions, three-level version questionnaire. When compared with treatment with sunitinib, treatment with lenvatinib plus pembrolizumab did not result in any clinically meaningful differences (as measured by predefined minimally important differences) in HRQoL measured using any of the three tools. Indirect clinical effectiveness evidence To compare the effectiveness of lenvatinib plus pembrolizumab versus relevant comparators other than sunitinib, the AG carried out Bayesian HR network meta-analyses. It was decided not to undertake a flexible modelling approach for network meta-analysis (NMA), which relaxes the proportional hazards (PH) assumption, such as fractional polynomial network meta-analyses because interpretation of the estimates provided by these complex modelling techniques can be difficult and results are often not intuitive. While deviance information criterion (DIC) statistics provide an approach to compare the fit of different models, they do not provide information about whether a model is a good fit to the data or whether the estimates generated by the model, including projections of results beyond the follow-up times of trials included in the NMA, are clinically plausible. Furthermore, flexible models, which appear similar according to model fit (i.e. according to DIC statistics), may generate very different long-term survival estimates. The AG assessed the feasibility of conducting Bayesian HR NMAs for the three population risk groups (intermediate-/poor-risk subgroup, favourable-risk subgroup and all-risk population) for all outcomes listed in the final scope issued by NICE. However, due to limited data availability, it was not possible to carry out NMAs for all outcomes for all three patient risk groups. Further, as networks were sparse, it was only possible to generate results using fixed-effect NMAs. The AG PFS NMA results for the intermediate-/poor-risk subgroup, the favourable-risk subgroup and the all-risk population should not be used to infer any statistically significant difference (or lack of statistically significant difference) for any of the treatment comparisons because of within-trial PH violations or uncertainty regarding the validity of the PHs assumption. The AG OS NMA results for the intermediate-/poor-risk subgroup suggested that there was a numerical, but not statistically significant, improvement in the OS for patients treated with lenvatinib plus pembrolizumab compared with patients treated with cabozantinib or nivolumab plus ipilimumab. Because of within-trial PH violations or uncertainty regarding the validity of the PH assumption, the AG OS NMA results for the favourable-risk subgroup and the all-risk population should not be used to infer any statistically significant difference (or lack of statistically significant difference) for any of the treatment comparisons. The AG objective tumour response rate NMA results for the intermediate-/poor-risk subgroup suggested that, although treatment with lenvatinib plus pembrolizumab led to a statistically significant improvement in objective tumour response rate compared to treatment nivolumab plus ipilimumab, it did not lead to a statistically significant improvement in objective tumour response rate for the comparison of lenvatinib plus pembrolizumab versus cabozantinib. It was not possible to generate results for the IMDC/MSKCC (Memorial Sloan-Kettering Cancer Center) favourable-risk subgroup due to data limitations. The AG objective tumour response rate NMA results for the all-risk population suggest that treatment with lenvatinib plus pembrolizumab led to a statistically significant improvement in objective tumour response rate versus treatment with sunitinib and versus treatment with pazopanib. The AG Grade ≥ 3 AE NMA results for the intermediate-/poor-risk subgroup suggested that treatment with lenvatinib plus pembrolizumab led to statistically significantly more Grade ≥ 3 AEs versus treatment with cabozantinib. It was not possible to generate results for the IMDC/MSKCC favourable-risk subgroup. The AG Grade ≥ 3 AE NMA results for the all-risk population suggested that treatment with lenvatinib led to statistically significantly more Grade ≥ 3 AEs versus treatment with sunitinib and versus treatment with pazopanib. Economic systematic review results The AG systematic review identified one relevant cost-effectiveness study. This study compared the cost-effectiveness of lenvatinib plus pembrolizumab versus sunitinib (and vs. other treatments). However, the study was undertaken from the perspective of the US healthcare system and generated results only for the all-risk population and included comparators that are not recommended by NICE as treatment options for patients with aRCC. Therefore, the extent to which these results were generalisable to the NHS was unclear. Cost-effectiveness analysis methods The Eisai and Merck Sharp & Dohme CSs to NICE included partitioned survival models built in Microsoft Excel. The AG considered that results from both models could be used to inform decision-making but that, in some instances, the companies could have made more appropriate assumptions and parameter choices. The AG did not develop a de novo economic model; instead, it modified the model provided by Merck Sharp & Dohme [referred to as the Merck Sharp & Dohme/Assessment Group (MSD/AG) model]. Neither of the companies produced cost-effectiveness results for the comparison of lenvatinib plus pembrolizumab versus nivolumab plus ipilimumab (intermediate-/poor-risk subgroup) despite both models having the functionality for this comparison. Furthermore, Eisai did not generate any cost-effectiveness results for the favourable-risk subgroup. The MSD/AG model was populated with OS, PFS and time to treatment discontinuation (TTD) data from the CLEAR trial (lenvatinib plus pembrolizumab versus sunitinib for favourable-risk subgroup and the all-risk population). The AG PFS and OS NMA results were used to estimate effectiveness for the comparison of lenvatinib plus pembrolizumab versus cabozantinib and versus nivolumab plus ipilimumab for the intermediate-/poor-risk population. NICE appraisal committees have concluded that sunitinib and pazopanib are of equivalent effectiveness and that, at best, tivozanib may have a similar effect to sunitinib or pazopanib. These conclusions were based on all-risk population data; the AG has assumed that this assumption holds for the favourable-risk population. The most important changes made by the AG to the Merck Sharp & Dohme model were different choices for estimating PFS, OS and TTD for the intervention and comparator treatments and for modelling two lines, rather than one line, of subsequent treatment. Cost-effectiveness analysis results The AG cost-effectiveness results presented in this report were estimated using list prices. Also, the AG cost-effectiveness results generated using confidential discounted prices were supplied to NICE in a confidential appendix, but cannot be presented here. For the intermediate-/poor-risk subgroup, the AG base-case cost-effectiveness results suggested that treatment with lenvatinib plus pembrolizumab generated more QALYs versus treatment with cabozantinib and versus nivolumab plus ipilimumab, but at a greater overall cost than either of these two treatments. Using list prices, the incremental cost-effectiveness ratios per QALY gained for the comparison of lenvatinib plus pembrolizumab versus cabozantinib and versus nivolumab plus ipilimumab exceed £100,000. For the favourable-risk subgroup, the AG base-case cost-effectiveness results suggested that treatment with sunitinib generated more QALYs than treatment with lenvatinib plus pembrolizumab at a lower overall cost, that is treatment with lenvatinib plus pembrolizumab was dominated by treatment with sunitinib (and, using the assumption of equivalent effectiveness, by pazopanib and tivozanib). The AG carried out extensive one-way sensitivity analyses, scenario analyses and probabilistic sensitivity analyses. Results from these analyses demonstrate that the AG base-case cost-effectiveness results are robust. Clinical and cost-effectiveness conclusions Good-quality clinical effectiveness evidence for the comparison of lenvatinib plus pembrolizumab versus sunitinib was available from the CLEAR trial. For most of the AG Bayesian HR NMA comparisons, it was difficult to reach conclusions due to within-trial PH violations or uncertainty regarding the validity of the PHs assumption. However, the data (clinical effectiveness and cost-effectiveness) used to populate the MSD/AG model are relevant to NHS clinical practice and can be used to inform NICE decision-making. The all-risk population comprises patients with intermediate-/poor-risk and patients with favourable-risk disease. The AG cost-effectiveness analyses have focused on the two subgroups, and the AG cost-effectiveness results, generated using list prices for all drugs, show that lenvatinib plus pembrolizumab is less cost-effective than all other treatment options.

ABSTRACT Mycobacterium tuberculosis (Mtb) as well as nontuberculous mycobacteria are intracellular pathogens whose treatment is extensive and increasingly impaired due to the rise of mycobacterial drug resistance. The loss of antibiotic efficacy has raised interest in the identification of host-directed therapeutics (HDT) to develop novel treatment strategies for mycobacterial infections. In this study, we identified amiodarone as a potential HDT candidate that inhibited both intracellular Mtb and Mycobacterium avium in primary human macrophages without directly impairing bacterial growth, thereby confirming that amiodarone acts in a host-mediated manner. Moreover, amiodarone induced the formation of (auto)phagosomes and enhanced autophagic targeting of mycobacteria in macrophages. The induction of autophagy by amiodarone is likely due to enhanced transcriptional regulation, as the nuclear intensity of the transcription factor EB, the master regulator of autophagy and lysosomal biogenesis, was strongly increased. Furthermore, blocking lysosomal degradation with bafilomycin impaired the host-beneficial effect of amiodarone. Finally, amiodarone induced autophagy and reduced bacterial burden in a zebrafish embryo model of tuberculosis, thereby confirming the HDT activity of amiodarone in vivo. In conclusion, we have identified amiodarone as an autophagy-inducing antimycobacterial HDT that improves host control of mycobacterial infections.IMPORTANCEDue to the global rise in antibiotic resistance, there is a strong need for alternative treatment strategies against intracellular bacterial infections, including Mycobacterium tuberculosis (Mtb) and non-tuberculous mycobacteria. Stimulating host defense mechanisms by host‐directed therapy (HDT) is a promising approach for treating mycobacterial infections. This study identified amiodarone, an antiarrhythmic agent, as a potential HDT candidate that inhibits the survival of Mtb and Mycobacterium avium in primary human macrophages. The antimycobacterial effect of amiodarone was confirmed in an in vivo tuberculosis model based on Mycobacterium marinum infection of zebrafish embryos. Furthermore, amiodarone induced autophagy and inhibition of the autophagic flux effectively impaired the host-protective effect of amiodarone, supporting that activation of the host (auto)phagolysosomal pathway is essential for the mechanism of action of amiodarone. In conclusion, we have identified amiodarone as an autophagy-inducing HDT that improves host control of a wide range of mycobacteria.

We present approaches using stochastic processes for the calculation of line broadening in plasmas. The derivation of model microfield methods (MMM) based on analytic formulations is recalled, as well as an approach using a simulation of the stochastic process. We discuss the possibility of an improvement of the stochastic process by comparing our first results to ab initio particle simulations coupled to a numerical integration of the emitters Schrödinger equation.

The prostone analog, lubiprostone, is approved to manage constipation-predominant irritable bowel syndrome. Lubiprostone also protects intestinal mucosal barrier function in animal models of colitis. The aim of this study was to determine if lubiprostone improves barrier properties in isolated colonic biopsies from Crohn's disease (CD) and ulcerative colitis (UC) patients. Sigmoid colon biopsies from healthy subjects, CD and UC patients in remission, and CD patients with active disease were mounted in Ussing chambers. Tissues were treated with lubiprostone or vehicle to determine the effects on transepithelial electrical resistance (TER), FITC-dextran 4kD (FD4) permeability, and electrogenic ion transport responses to forskolin and carbachol. Localization of the tight junction protein, occludin, was determined by immunofluorescence. Lubiprostone significantly increased ion transport across control, CD and UC remission biopsies but not active CD. Lubiprostone selectively improved TER in both CD remission and active disease biopsies but not in control or UC biopsies. The improved TER was associated with increased membrane localization of occludin. Lubiprostone selectively improved barrier properties of biopsies from CD patients vs. UC and independent of an ion transport response. These data indicate that lubiprostone has potential efficacy in improving mucosal integrity in Crohn's disease.

* Context.--Progressive independence in medicine is critical to building confidence and decisiveness in trainees. However, this can be difficult to accomplish in the strict regulatory environment of pathology. Objective.--To pilot and adopt a process whereby surgical pathology fellows independently manage a subset of cases and release preliminary reports. Design.--Upon program approval, board-certified surgical pathology fellows were eligible for preliminary report sign-out at their discretion. Eligible cases were sent from outside institutions for confirmatory review. Preliminary reports were viewable in the electronic medical record. Safety measures were used to ensure timely release of final reports by attending pathologists. Results.--Fellows participating in the pilot (n = 4) released 59 preliminary reports out of 101 cases reviewed (58%), with 1 potentially significant discrepancy between preliminary and final report. Turnaround time was not affected. The process was endorsed by all participants and adopted as standard practice. During the first year, eligible fellows (n = 8) released 123 preliminary reports out of 1260 cases reviewed (9.8%). There were no major diagnostic discrepancies and no effects on turnaround time. The number of preliminary reports released by each fellow was variable (range, 2-48; median, 8), likely a reflection of both external factors (number of trainees on service, volume) and trainee-specific factors (confidence, efficiency). Conclusions.--Fellows showed good judgment when independently managing cases, with just 1 potentially significant discrepancy out of 182 cases ( doi: 10.5858/arpa.2022-0223-OA, Increasing resident and fellow independence as they progress through training is a cornerstone of medical education. Medical educators and trainees perceive many benefits from resident/fellow autonomy, including increased confidence and [...]

Condensed Matter - Materials Science - Abstract
Surface strain often controls properties of the material including charge transport and chemical reactivity. Localized surface strain is measured with atomic resolution on (111) ceria nanoparticle surfaces using environmental transmission electron microscopy under different redox conditions. Density Functional Theory (DFT) coupled with TEM image simulations have been used for aid in interpreting the experimental data. Oxygen vacancy creation/annihilation introduces strain at surface and near surface regions on cation sublattice. Static and fluxional strainmaps are generated from images at these different conditions and compared. While fluxional strain is highest at locations associated with unstable vacancies at active sites, highly inhomogeneous static strain fields comprising of alternating tensile/compressing strain is seen at surface and subsurfaces linked to the presence of stable oxygen vacancies. Interestingly, both stable and unstable oxygen vacancies are found within a few atomic spacing of each other on the same surface. The static strain pattern depends on the ambient inside TEM. Oxidizing environments tend to lower vacancy concentrations at the surface whereas a highly reducing environment created using high electron dose creates oxygen vacancies everywhere (bulk and surfaces) in the nanoparticle.

Computer Science - Computer Vision and Pattern Recognition ,Computer Science - Artificial Intelligence - Abstract
Ophthalmic images and derivatives such as the retinal nerve fiber layer (RNFL) thickness map are crucial for detecting and monitoring ophthalmic diseases (e.g., glaucoma). For computer-aided diagnosis of eye diseases, the key technique is to automatically extract meaningful features from ophthalmic images that can reveal the biomarkers (e.g., RNFL thinning patterns) linked to functional vision loss. However, representation learning from ophthalmic images that links structural retinal damage with human vision loss is non-trivial mostly due to large anatomical variations between patients. The task becomes even more challenging in the presence of image artifacts, which are common due to issues with image acquisition and automated segmentation. In this paper, we propose an artifact-tolerant unsupervised learning framework termed EyeLearn for learning representations of ophthalmic images. EyeLearn has an artifact correction module to learn representations that can best predict artifact-free ophthalmic images. In addition, EyeLearn adopts a clustering-guided contrastive learning strategy to explicitly capture the intra- and inter-image affinities. During training, images are dynamically organized in clusters to form contrastive samples in which images in the same or different clusters are encouraged to learn similar or dissimilar representations, respectively. To evaluate EyeLearn, we use the learned representations for visual field prediction and glaucoma detection using a real-world ophthalmic image dataset of glaucoma patients. Extensive experiments and comparisons with state-of-the-art methods verified the effectiveness of EyeLearn for learning optimal feature representations from ophthalmic images., Comment: 10 pages

Computer Science - Sound ,Electrical Engineering and Systems Science - Audio and Speech Processing ,Mathematics - Number Theory - Abstract
Equal temperament, in which semitones are tuned in the irrational ratio of $2^{1/12} : 1$, is best seen as a serviceable compromise, sacrificing purity for flexibility. Just intonation, in which intervals are given by products of powers of $2$, $3$, and $5$, is more natural, but of limited flexibility. We propose a new scheme in which ratios of Gaussian integers form the basis of an abstract tonal system. The tritone, so problematic in just temperament, given ambiguously by the ratios $\tfrac{45}{32}$, $\tfrac{64}{45}$, $\tfrac{36}{25}$, $\tfrac{25}{18}$, none satisfactory, is in our scheme represented by the complex ratio $1 + \rm{i} : 1$. The major and minor whole tones, given by intervals of $\tfrac{9}{8}$ and $\tfrac{10}{9}$, can each be factorized into products of complex semitones, giving us a major complex semitone $\tfrac{3}{4}(1 + \rm{i})$ and a minor complex semitone $\tfrac{1}{3}(3 + \rm{i})$. The perfect third, given by the interval $\tfrac{5}{4}$, factorizes into the product of a complex whole tone $\tfrac{1}{2}(1 + 2\rm{i})$ and its complex conjugate. Augmented with these supplementary tones, the resulting scheme of complex intervals based on products of low powers of Gaussian primes leads to the construction of a complete system of major and minor scales in all keys., Comment: 35 pages, to appear in Journal of Mathematics and Music

Boland, Geraldine and Guerin, Suzanne
- Abstract
Deinstitutionalisation has increased the likelihood of adults with intellectual disabilities residing in neighbourhoods either in staff-supported accommodation or in their family home. However, it raises the question of whether national policies on disability have translated into practice actions by service providers that result in positive social inclusion outcomes for individuals. This study examined the practice initiatives supporting social inclusion in neighbourhoods in specialist state-funded service providers for adults with intellectual disabilities. Using a mixed methods design, CEOs/service leaders of 40 organisations completed an online survey. Follow-up interviews were completed with a randomised sample. Shifting towards new service models and strategic links with mainstream organisations were most often mentioned as furthering social inclusion goals. A wide range of service initiatives were reported, with positive outcomes alongside a range of challenges. Service providers play an important role in providing individualised supports that foster local engagement. However, the service context is complex and service leaders have reported many challenges that may impede progress on social inclusion.

Abstract Background In 2021, an Ebola virus disease (EVD) outbreak was declared in Guinea, linked to persistent virus from the 2014–2016 West Africa Epidemic. This paper analyzes factors associated with contact tracing reliability (defined as completion of a 21-day daily follow-up) during the 2021 outbreak, and transitively, provides recommendations for enhancing contact tracing reliability in future. Methods We conducted a descriptive and analytical cross-sectional study using multivariate regression analysis of contact tracing data from 1071 EVD contacts of 23 EVD cases (16 confirmed and 7 probable). Results Findings revealed statistically significant factors affecting contact tracing reliability. Unmarried contacts were 12.76× more likely to miss follow-up than those married (OR = 12.76; 95% CI [3.39–48.05]; p
