Abstract

Abstract In recent years, agroecology has gained prominence as one of the innovative approaches to agriculture that could positively contribute to achieving sustainable food systems. As a transdisciplinary science, agroecology could benefit from the contribution of socio-economic sciences. This study aims to give an overview of how scholars have approached socio-economic issues in the field of agroecology. A scoping review was conducted by using the PRISMA-ScR method, searching both Scopus and Web of Sciences databases. The selected body of literature (183 articles) provides an overview of the key socio-economic dimensions analysed in the literature on agroecology and the results achieved by scholars. The findings allowed drawing the research gaps and the future research directions in this domain.

Abstract

Background: Cesarean scar pregnancy (CSP) has become more frequent as a direct consequence of the increased number of cesarean deliveries and the advances in imaging. Although some cases are characterized by spontaneous resolution, unrecognized or mishandled CSP has the potential to cause both fetal and maternal morbidity and mortality. However, due to its infrequency, there is no agreement on the best management. Objective: The purpose of this study was to evaluate the safety, the risks and effectiveness of medical therapy with methotrexate and mifepristone to better understand its role in CSP therapy. Design: This study is a systematic review. Data Sources and Methods: The electronic databases PubMed, Medline, and Scopus were comprehensively searched until December 2023. Medical Subject Headings terms (Cesarean scar pregnancy) AND (Methotrexate) AND (Mifepristone) AND (Medical Therapy) were used to identify the relevant records. Due to the rarity of this pathology, the studies included are all case reports or case series. The methodological quality of the included studies was assessed using the JBI Critical Appraisal Checklist for case reports. Results: We included in our review a total of seven cases reported in five manuscripts at the end of the screening process. Our review suggests that this type of combination treatment can be considered. The success rate is 71.4%. Treatment seems to be most effective when beta human chorionic gonadotropin (B-hCG) is below 5,000 mUi/ml and when the gestational sac is less than 20 mm. The absence of fetal heartbeat seems to be a positive prognostic factor for a positive outcome. Conclusion: Methotrexate and mifepristone administration can be considered as an alternative first-line effective treatment, especially in case of pregnancy with B-hCG

Abstract

Objetivo: Apresentar o perfil dos pacientes transplantados pelo projeto PROADI SUS na Instituição. Métodos: Estudo de coorte retrospectivo composto por 41 pacientes de ambos os sexos, com idades entre 3 e 66 anos. Os critérios de exclusão foram pacientes indeferidos pelo time assistencial. Todos os pacientes foram regulados via SNT. Foram analisados dados demográficos, clínicos, de comorbidade, doença, transplante, doador e desfecho. Resultados: Dos 41 pacientes atendidos, 51% (21) eram provenientes do estado de São Paulo, 27% (11) do Distrito Federal, 12% (5) de Sergipe, 4,9% (2) da Bahia, 2,4% (1) do Pará e 2,4% (1) do Espírito Santo. Em relação aos dados da doença, os diagnósticos predominantes foram leucemia mieloide aguda (41%) e leucemia linfoblástica aguda (20%). Os dados do transplante indicaram que 51% foram alogênicos haploidênticos, 39% alogênicos aparentados e 9,8% alogênicos não aparentados. Ao avaliar o tipo de condicionamento, 56% foram mieloablativos. No pós-transplante, 46% dos pacientes tiveram Doença do Enxerto Contra Hospedeiro (DECH), mas nenhum apresentou DECH crônica. Analisando a sobrevida pelo método Kaplan-Meier, a sobrevida em 30 dias foi de 95,12% e em 100 dias foi de 87,07%, comparado a dados do CIBMTR que estimam uma sobrevida de 80,0%. Conclusão: Este estudo demonstrou que os pacientes atendidos pelo projeto na Instituição apresentaram taxas de sobrevida superiores às estimativas do CIBMTR. A oportunidade de garantir acesso ao transplante de medula óssea, reforçando a importância de iniciativas como essa para a qualificação contínua dos programas de TMO no Brasil.

Abstract

Objetivo: Identificar os obstáculos na execução das atividades de melhorias propostas em 9 instituições transplantadoras participantes do Projeto PROADI SUS- MAIS TMO. Material e método: Trata- se de um estudo descritivo realizado com equipes de TMO de nove Instituições transplantadoras de 4 regiões do Brasil participantes do Projeto PROADI SUS- MAIS TMO no período de agosto de 2022 a dezembro de 2023. Foram realizados nas unidades de TMO de cada Instituição, uma visita diagnóstica com a finalidade de conhecer estrutura, fluxos, processos e indicadores e proposto plano de ação de melhorias. Cada plano de ação apresentou em média 60 atividades propostas a serem realizadas pelos centros. Essas atividades foram monitoradas por compartilhamento do plano via Sharepoint, reuniões quinzenais gravadas via internet, visitas de monitoria para discussão, apresentação das melhorias e a aplicação do método TRACER para verificar a aplicabilidade das melhorias no fluxo do paciente. As atividades de melhoria foram classificadas no plano de ação como: Concluída, Em andamento, Não iniciadas ou Inexecutáveis. Os dados foram analisados de forma qualitativa. Resultados: Após o acompanhamento das 9 instituições foram totalizadas 534 ações de melhoria monitoradas. Dentre estas 311 (58%) foram concluídas, 50 (10%) estavam em andamento, 26 (5%) não foram iniciadas, 60 (11%) permaneceram em atraso e 87(16%) foram consideradas como inexecutáveis pelo centros. Discussão: As atividades de melhorias propostas não concluídas, não iniciadas e em atraso tiveram como principais motivos a morosidade dos processos, dimensionamento de recursos humanos e tempo hábil para a execução das ações. As classificadas pelos centros como inexecutáveis, foram por falta de processos definidos, recursos financeiros, RH insuficiente, fragilidades de estrutura física e pendências de contratos administrativos. Conclusão: As equipes participantes do projeto demonstraram interesse e engajamento para realização das atividades propostas, porém os motivos das atividades não finalizadas e inexecutáveis podem gerar obstáculos na melhoria dos processos para crescimento do serviços principalmente em aumentar o número de transplantes realizados visando qualidade nos processos e segurança do paciente.

Abstract

A relação com o corpo e com a alimentação tem sido impactada pelo ambiente obesogênico, tema escasso na literatura que afeta mulheres e necessita de métodos de investigação em profundidade. O objetivo deste estudo foi acessar e explorar o reconhecimento da relação com o corpo e a alimentação de mulheres participantes de uma intervenção educativa para a consciência alimentar por meio do mapa corporal narrado, uma metodologia visual. Trata-se de uma pesquisa qualitativa, conduzida com 19 mulheres brasileiras, que construíram o mapa corporal individualmente, analisado considerando representações visuais e narrativas. Formas de autodenominação foram reconhecidas por temas que demonstraram como aspectos da identidade definiram ou intensificaram a relação com o corpo e a alimentação. Este estudo contribuiu com uma estratégia para programas educativos de alimentação e nutrição para o fortalecimento da saúde de mulheres.

Abstract

O regime internacional de responsabilidade civil e compensação em casos de poluição por derramamento de óleo é composto por quatro convenções de características próprias no âmbito internacional, adotando o princípio da canalização da responsabilidade objetiva na figura do dono do navio e competência territorial baseada no local do dano. Conta, ainda, com dois Fundos que visam garantir a compensação das vítimas. Paralelamente, realidade inegável na atualidade do comércio marítimo atual, as bandeiras de conveniência ganharam grande visibilidade após se envolverem em vários dos maiores desastres marítimo-ambientais ocorridos nos últimos 50 anos. Através dos métodos indutivo, histórico e empírico-quantitativo, propõe-se a conceituar e definir “bandeiras de conveniência”; analisar os dados relativos ao transporte marinho de óleo por petroleiros a fim de se determinar se esses registros de fato acarretam maiores níveis de poluição em comparação com outras bandeiras e em que proporção e, a partir disso, apontar perspectivas e impressões que permitam realizar um balanço das convenções de responsabilidade e compensação, juntamente com os Fundos IOPC, no que toca o combate à poluição marítima por petroleiros. Observou-se que, embora bandeiras de conveniência tenham acompanhado uma tendência positiva, sua prática complacente ainda representa uma grande ameaça socioeconômica e ambiental uma vez que potencializa riscos em uma atividade que por si só já é de alto grau de risco, preocupando, principalmente, pela severidade dos acidentes.

Abstract

Hypereosinophilic syndromes (HES) represent a group of rare dis-immune conditions characterized by blood hyper-eosinophilia and eosinophilic related burden. Especially the idiopathic subtype (I-HES) is particularly difficult to diagnose because of its heterogeneous clinical presentation, the lack of specific findings on physical exam, lab tools, and imaging informative enough to unequivocally confirm the diagnosis and the overlap with other entities, including eosinophilic organ-diseases or systemic dis-immune conditions other than I-HES (from atopy to eosinophilic granulomatosis with polyangiitis [EGPA], the last often extremely difficult to distinguish from HES). Taken together, all the features mentioned above account for an extremely difficult early recognition HES and on-time referral to a specialized centre. The referral itself is challenging due to a not univocal specialist identification, because of the variability of physicians managing HES in different settings (including allergist/clinical immunologist, haematologist, internal medicine doctors, pulmonologist, rheumatologist). Furthermore, the approach in terms of personalized treatment identification and follow-up plan (timing, organ assessment), is poorly standardized. Further translational and clinical research is needed to address the mentioned unmet needs, but on practical grounds increasing the overall clinicians’ awareness on HES and implementing healthcare pathways for HES patients represent a roadmap that every clinician might try to realize in his specific setting.The present review aims at providing an overview about the current challenges and unmet needs in the practical approach to HES and rare hypereosinophilic allergo-immunological diseases, including a proposal for an innovative multidisciplinary organizational model.

Abstract

When the Canonical Ramsey's Theorem by Erd\H{o}s and Rado is applied to regressive functions one obtains the Regressive Ramsey's Theorem by Kanamori and McAloon. Taylor proved a "canonical" version of Hindman's Theorem, analogous to the Canonical Ramsey's Theorem. We introduce the restriction of Taylor's Canonical Hindman's Theorem to a subclass of the regressive functions, the $\lambda$-regressive functions, relative to an adequate version of min-homogeneity and prove some results about the Reverse Mathematics of this Regressive Hindman's Theorem and of natural restrictions of it. In particular we prove that the first non-trivial restriction of the principle is equivalent to Arithmetical Comprehension. We furthermore prove that this same principle strongly computably reduces the well-ordering-preservation principle for base-$\omega$ exponentiation., Comment: Corrected proofs of Proposition 2. Added Theorem 2

Abstract

The Gaia mission of the European Space Agency (ESA) has been routinely observing Solar System objects (SSOs) since the beginning of its operations in August 2014. The Gaia data release three (DR3) includes, for the first time, the mean reflectance spectra of a selected sample of 60 518 SSOs, primarily asteroids, observed between August 5, 2014, and May 28, 2017. Each reflectance spectrum was derived from measurements obtained by means of the Blue and Red photometers (BP/RP), which were binned in 16 discrete wavelength bands. We describe the processing of the Gaia spectral data of SSOs, explaining both the criteria used to select the subset of asteroid spectra published in Gaia DR3, and the different steps of our internal validation procedures. In order to further assess the quality of Gaia SSO reflectance spectra, we carried out external validation against SSO reflectance spectra obtained from ground-based and space-borne telescopes and available in the literature. For each selected SSO, an epoch reflectance was computed by dividing the calibrated spectrum observed by the BP/RP at each transit on the focal plane by the mean spectrum of a solar analogue. The latter was obtained by averaging the Gaia spectral measurements of a selected sample of stars known to have very similar spectra to that of the Sun. Finally, a mean of the epoch reflectance spectra was calculated in 16 spectral bands for each SSO. The agreement between Gaia mean reflectance spectra and those available in the literature is good for bright SSOs, regardless of their taxonomic spectral class. We identify an increase in the spectral slope of S-type SSOs with increasing phase angle. Moreover, we show that the spectral slope increases and the depth of the 1 um absorption band decreases for increasing ages of S-type asteroid families., Comment: 30 pages, 26 figures

Abstract

With the most recent Gaia data release the number of sources with complete 6D phase space information (position and velocity) has increased to well over 33 million stars, while stellar astrophysical parameters are provided for more than 470 million sources, in addition to the identification of over 11 million variable stars. Using the astrophysical parameters and variability classifications provided in Gaia DR3, we select various stellar populations to explore and identify non-axisymmetric features in the disc of the Milky Way in both configuration and velocity space. Using more about 580 thousand sources identified as hot OB stars, together with 988 known open clusters younger than 100 million years, we map the spiral structure associated with star formation 4-5 kpc from the Sun. We select over 2800 Classical Cepheids younger than 200 million years, which show spiral features extending as far as 10 kpc from the Sun in the outer disc. We also identify more than 8.7 million sources on the red giant branch (RGB), of which 5.7 million have line-of-sight velocities, allowing the velocity field of the Milky Way to be mapped as far as 8 kpc from the Sun, including the inner disc. The spiral structure revealed by the young populations is consistent with recent results using Gaia EDR3 astrometry and source lists based on near infrared photometry, showing the Local (Orion) arm to be at least 8 kpc long, and an outer arm consistent with what is seen in HI surveys, which seems to be a continuation of the Perseus arm into the third quadrant. Meanwhile, the subset of RGB stars with velocities clearly reveals the large scale kinematic signature of the bar in the inner disc, as well as evidence of streaming motions in the outer disc that might be associated with spiral arms or bar resonances.

Abstract

The third Gaia data release provides photometric time series covering 34 months for about 10 million stars. For many of those stars, a characterisation in Fourier space and their variability classification are also provided. This paper focuses on intermediate- to high-mass (IHM) main sequence pulsators M >= 1.3 Msun) of spectral types O, B, A, or F, known as beta Cep, slowly pulsating B (SPB), delta Sct, and gamma Dor stars. These stars are often multi-periodic and display low amplitudes, making them challenging targets to analyse with sparse time series. All datasets used in this analysis are part of the Gaia DR3 data release. The photometric time series were used to perform a Fourier analysis, while the global astrophysical parameters necessary for the empirical instability strips were taken from the Gaia DR3 gspphot tables, and the vsini data were taken from the Gaia DR3 esphs tables. We show that for nearby OBAF-type pulsators, the Gaia DR3 data are precise and accurate enough to pinpoint them in the Hertzsprung-Russell diagram. We find empirical instability strips covering broader regions than theoretically predicted. In particular, our study reveals the presence of fast rotating gravity-mode pulsators outside the strips, as well as the co-existence of rotationally modulated variables inside the strips as reported before in the literature. We derive an extensive period-luminosity relation for delta Sct stars and provide evidence that the relation features different regimes depending on the oscillation period. Finally, we demonstrate how stellar rotation attenuates the amplitude of the dominant oscillation mode of delta Sct stars.

Abstract

Gaia Data Release 3 (DR3) provides a wealth of new data products for the astronomical community to exploit, including astrophysical parameters for a half billion stars. In this work we demonstrate the high quality of these data products and illustrate their use in different astrophysical contexts. We query the astrophysical parameter tables along with other tables in Gaia DR3 to derive the samples of the stars of interest. We validate our results by using the Gaia catalogue itself and by comparison with external data. We have produced six homogeneous samples of stars with high quality astrophysical parameters across the HR diagram for the community to exploit. We first focus on three samples that span a large parameter space: young massive disk stars (~3M), FGKM spectral type stars (~3M), and UCDs (~20K). We provide these sources along with additional information (either a flag or complementary parameters) as tables that are made available in the Gaia archive. We furthermore identify 15740 bone fide carbon stars, 5863 solar-analogues, and provide the first homogeneous set of stellar parameters of the Spectro Photometric Standard Stars. We use a subset of the OBA sample to illustrate its usefulness to analyse the Milky Way rotation curve. We then use the properties of the FGKM stars to analyse known exoplanet systems. We also analyse the ages of some unseen UCD-companions to the FGKM stars. We additionally predict the colours of the Sun in various passbands (Gaia, 2MASS, WISE) using the solar-analogue sample., Comment: 35 pages, (incl 6 pages references, acknowledgements, affiliations), 37 figures, A&A accepted

Abstract

The Gaia Galactic survey mission is designed and optimized to obtain astrometry, photometry, and spectroscopy of nearly two billion stars in our Galaxy. Yet as an all-sky multi-epoch survey, Gaia also observes several million extragalactic objects down to a magnitude of G~21 mag. Due to the nature of the Gaia onboard selection algorithms, these are mostly point-source-like objects. Using data provided by the satellite, we have identified quasar and galaxy candidates via supervised machine learning methods, and estimate their redshifts using the low resolution BP/RP spectra. We further characterise the surface brightness profiles of host galaxies of quasars and of galaxies from pre-defined input lists. Here we give an overview of the processing of extragalactic objects, describe the data products in Gaia DR3, and analyse their properties. Two integrated tables contain the main results for a high completeness, but low purity (50-70%), set of 6.6 million candidate quasars and 4.8 million candidate galaxies. We provide queries that select purer sub-samples of these containing 1.9 million probable quasars and 2.9 million probable galaxies (both 95% purity). We also use high quality BP/RP spectra of 43 thousand high probability quasars over the redshift range 0.05-4.36 to construct a composite quasar spectrum spanning restframe wavelengths from 72-100 nm., Comment: Accepted to A&A

Abstract

The Gaia DR3 Catalogue contains for the first time about eight hundred thousand solutions with either orbital elements or trend parameters for astrometric, spectroscopic and eclipsing binaries, and combinations of them. This paper aims to illustrate the huge potential of this large non-single star catalogue. Using the orbital solutions together with models of the binaries, a catalogue of tens of thousands of stellar masses, or lower limits, partly together with consistent flux ratios, has been built. Properties concerning the completeness of the binary catalogues are discussed, statistical features of the orbital elements are explained and a comparison with other catalogues is performed. Illustrative applications are proposed for binaries across the H-R diagram. The binarity is studied in the RGB/AGB and a search for genuine SB1 among long-period variables is performed. The discovery of new EL CVn systems illustrates the potential of combining variability and binarity catalogues. Potential compact object companions are presented, mainly white dwarf companions or double degenerates, but one candidate neutron star is also presented. Towards the bottom of the main sequence, the orbits of previously-suspected binary ultracool dwarfs are determined and new candidate binaries are discovered. The long awaited contribution of Gaia to the analysis of the substellar regime shows the brown dwarf desert around solar-type stars using true, rather than minimum, masses, and provides new important constraints on the occurrence rates of substellar companions to M dwarfs. Several dozen new exoplanets are proposed, including two with validated orbital solutions and one super-Jupiter orbiting a white dwarf, all being candidates requiring confirmation. Beside binarity, higher order multiple systems are also found., Comment: 60 pages, 60 figures. Accepted for publication in Astronomy & Astrophysics (2022-06-09). The catalogue of binary masses is available for download from the ESA Gaia DR3 Archive and will be available from the CDS/VizieR service

Abstract

Gaia DR3 opens a new era of all-sky spectral analysis of stellar populations thanks to the nearly 5.6 million stars observed by the RVS and parametrised by the GSP-spec module. The all-sky Gaia chemical cartography allows a powerful and precise chemo-dynamical view of the Milky Way with unprecedented spatial coverage and statistical robustness. First, it reveals the strong vertical symmetry of the Galaxy and the flared structure of the disc. Second, the observed kinematic disturbances of the disc -- seen as phase space correlations -- and kinematic or orbital substructures are associated with chemical patterns that favour stars with enhanced metallicities and lower [alpha/Fe] abundance ratios compared to the median values in the radial distributions. This is detected both for young objects that trace the spiral arms and older populations. Several alpha, iron-peak elements and at least one heavy element trace the thin and thick disc properties in the solar cylinder. Third, young disc stars show a recent chemical impoverishment in several elements. Fourth, the largest chemo-dynamical sample of open clusters analysed so far shows a steepening of the radial metallicity gradient with age, which is also observed in the young field population. Finally, the Gaia chemical data have the required coverage and precision to unveil galaxy accretion debris and heated disc stars on halo orbits through their [alpha/Fe] ratio, and to allow the study of the chemo-dynamical properties of globular clusters. Gaia DR3 chemo-dynamical diagnostics open new horizons before the era of ground-based wide-field spectroscopic surveys. They unveil a complex Milky Way that is the outcome of an eventful evolution, shaping it to the present day (abridged)., Comment: Astronomy and Astrophysics (accepted, in press)

Abstract

Stimulator of interferon genes (STING) is a mediator of immune recognition of cytosolic DNA, which plays important roles in cancer, cytotoxic therapies, and infections with certain pathogens. Although pharmacologic STING activation stimulates potent antitumor immune responses in animal models, clinically applicable pharmacodynamic biomarkers that inform of the magnitude, duration, and location of immune activation elicited by systemic STING agonists are yet to be described. We investigated whether systemic STING activation induces metabolic alterations in immune cells that can be visualized by PET imaging. Methods: C57BL/6 mice were treated with systemic STING agonists and imaged with 18F-FDG PET after 24 h. Splenocytes were harvested 6 h after STING agonist administration and analyzed by single-cell RNA sequencing and flow cytometry. 18F-FDG uptake in total splenocytes and immunomagnetically enriched splenic B and T lymphocytes from STING agonist-treated mice was measured by γ-counting. In mice bearing prostate or pancreas cancer tumors, the effects of STING agonist treatment on 18F-FDG uptake, T-lymphocyte activation marker levels, and tumor growth were evaluated. Results: Systemic delivery of structurally distinct STING agonists in mice significantly increased 18F-FDG uptake in the spleen. The average spleen SUVmax in control mice was 1.90 (range, 1.56-2.34), compared with 4.55 (range, 3.35-6.20) in STING agonist-treated mice (P < 0.0001). Single-cell transcriptional and flow cytometry analyses of immune cells from systemic STING agonist-treated mice revealed enrichment of a glycolytic transcriptional signature in both T and B lymphocytes that correlated with the induction of immune cell activation markers. In tumor-bearing mice, STING agonist administration significantly delayed tumor growth and increased 18F-FDG uptake in secondary lymphoid organs. Conclusion: These findings reveal hitherto unknown functional links between STING signaling and immunometabolism and suggest that 18F-FDG PET may provide a widely applicable approach toward measuring the pharmacodynamic effects of systemic STING agonists at a whole-body level and guiding their clinical development.

Abstract

Objective Given fibromyalgia (FM) frequently co‐occurs with autoimmune disease, this study was initiated to objectively evaluate FM in a multiracial/ethnic cohort of patients with systemic lupus erythematosus (SLE). Methods Patients with SLE were screened for FM using the 2016 FM classification criteria during an in‐person rheumatologist visit. We evaluated hybrid Safety of Estrogens in Lupus National Assessment (SELENA)‐SLE Disease Activity Index (SLEDAI) scores, SLE classification criteria, and Systemic Lupus International Collaborating Clinics damage index. We compared patients with and without FM and if differences were present, compared patients with FM with patients with non‐FM related chronic pain. Results 316 patients with SLE completed the FM questionnaire. 55 (17.4%) met criteria for FM. The racial composition of patients with FM differed from those without FM (P = 0.023), driven by fewer Asian patients having FM. There was no difference in SLE disease duration, SELENA‐SLEDAI score, or active serologies. There was more active arthritis in the FM group (16.4%) versus the non‐FM group (1.9%) (P

Abstract

Abstract Hematopoietic stem cell gene therapy (GT) using a γ-retroviral vector (γ-RV) is an effective treatment for Severe Combined Immunodeficiency due to Adenosine Deaminase deficiency. Here, we describe a case of GT-related T-cell acute lymphoblastic leukemia (T-ALL) that developed 4.7 years after treatment. The patient underwent chemotherapy and haploidentical transplantation and is currently in remission. Blast cells contain a single vector insertion activating the LIM-only protein 2 (LMO2) proto-oncogene, confirmed by physical interaction, and low Adenosine Deaminase (ADA) activity resulting from methylation of viral promoter. The insertion is detected years before T-ALL in multiple lineages, suggesting that further hits occurred in a thymic progenitor. Blast cells contain known and novel somatic mutations as well as germline mutations which may have contributed to transformation. Before T-ALL onset, the insertion profile is similar to those of other ADA-deficient patients. The limited incidence of vector-related adverse events in ADA-deficiency compared to other γ-RV GT trials could be explained by differences in transgenes, background disease and patient’s specific factors.

Abstract

Abstract Background Leveraging the Accelerating Medicines Partnership (AMP) Lupus Nephritis (LN) dataset, we evaluated longitudinal patterns, rates, and predictors of response to standard-of-care therapy in patients with lupus nephritis. Methods Patients from US academic medical centers with class III, IV, and/or V LN and a baseline urine protein/creatinine (UPCR) ratio ≥ 1.0 (n = 180) were eligible for this analysis. Complete response (CR) required the following: (1) UPCR 50% reduction in UPCR; (2) normal serum creatinine or, if abnormal, ≤ 125% of baseline; and (3) prednisone dose ≤ 15 mg/day. Results Response rates to the standard of care at week 52 were CR = 22.2%; PR = 21.7%; non-responder (NR) = 41.7%, and not determined (ND) = 14.4%. Only 8/180 (4.4%) patients had a week 12 CR sustained through week 52. Eighteen (10%) patients attained a week 12 PR or CR and sustained their responses through week 52 and 47 (26.1%) patients achieved sustained PR or CR at weeks 26 and 52. Week 52 CR or PR attainment was associated with baseline UPCR > 3 (ORadj = 3.71 [95%CI = 1.34–10.24]; p = 0.012), > 25% decrease in UPCR from baseline to week 12 (ORadj = 2.61 [95%CI = 1.07–6.41]; p = 0.036), lower chronicity index (ORadj = 1.33 per unit decrease [95%CI = 1.10–1.62]; p = 0.003), and positive anti-dsDNA antibody (ORadj = 2.61 [95%CI = 0.93–7.33]; p = 0.069). Conclusions CR and PR rates at week 52 were consistent with the standard-of-care response rates observed in prospective registrational LN trials. Low sustained response rates underscore the need for more efficacious therapies and highlight how critically important it is to understand the molecular pathways associated with response and non-response.

Abstract

Gaia-CRF3 is the celestial reference frame for positions and proper motions in the third release of data from the Gaia mission, Gaia DR3 (and for the early third release, Gaia EDR3, which contains identical astrometric results). The reference frame is defined by the positions and proper motions at epoch 2016.0 for a specific set of extragalactic sources in the (E)DR3 catalogue. We describe the construction of Gaia-CRF3, and its properties in terms of the distributions in magnitude, colour, and astrometric quality. Compact extragalactic sources in Gaia DR3 were identified by positional cross-matching with 17 external catalogues of quasars (QSO) and active galactic nuclei (AGN), followed by astrometric filtering designed to remove stellar contaminants. Selecting a clean sample was favoured over including a higher number of extragalactic sources. For the final sample, the random and systematic errors in the proper motions are analysed, as well as the radio-optical offsets in position for sources in the third realisation of the International Celestial Reference Frame (ICRF3). The Gaia-CRF3 comprises about 1.6 million QSO-like sources, of which 1.2 million have five-parameter astrometric solutions in Gaia DR3 and 0.4 million have six-parameter solutions. The sources span the magnitude range G = 13 to 21 with a peak density at 20.6 mag, at which the typical positional uncertainty is about 1 mas. The proper motions show systematic errors on the level of 12 ${\mu}$as yr${}^{-1}$ on angular scales greater than 15 deg. For the 3142 optical counterparts of ICRF3 sources in the S/X frequency bands, the median offset from the radio positions is about 0.5 mas, but exceeds 4 mas in either coordinate for 127 sources. We outline the future of the Gaia-CRF in the next Gaia data releases.
