An Intersectional Analysis of Child and Adolescent Inclusion in Local Participation Processes
Educational and social initiatives promoting participation among children and adolescents struggle with the widely‐held notion that non‐adult stages of life are merely transitory and that, therefore, non‐adults' views on public life are of less value. Apart from this hurdle of adult‐centrism, there are other obstacles to the full participation of this segment of the population. The present study analyses the inbuilt structures that help or hinder children and adolescents' participation in the local arena. Being ascribed to one or other of the social categories (gender, origins, racialisation, economic status, functional diversity, physical and mental health, gender identity), in addition to being a child or adolescent, involves a further difficulty in exercising one's rights in general and the right of participation in particular, and this weakens young people's social inclusion and exercise of citizenship, deepening their social vulnerability. This is where the intersectional approach can help us avoid the exclusion of children and adolescents with added social barriers. In this article, we survey 191 local youth workers to determine their perceptions of inclusivity in child participation bodies in their municipality. The specific measures in place are also discussed. Lastly, we identify the challenges to children's inclusion in local participation processes and some strategies for advancing towards the creation of more diverse and inclusive arenas of participation
Large T cell clones expressing immune checkpoints increase during multiple myeloma evolution and predict treatment resistance
Large T cell; Immune checkpoints; Multiple myelomaCèl·lules T grans; Punts de control immunitari; Mieloma múltipleCélulas T grandes; Puntos de control inmunitario; Mieloma múltipleTumor recognition by T cells is essential for antitumor immunity. A comprehensive characterization of T cell diversity may be key to understanding the success of immunomodulatory drugs and failure of PD-1 blockade in tumors such as multiple myeloma (MM). Here, we use single-cell RNA and T cell receptor sequencing to characterize bone marrow T cells from healthy adults (n = 4) and patients with precursor (n = 8) and full-blown MM (n = 10). Large T cell clones from patients with MM expressed multiple immune checkpoints, suggesting a potentially dysfunctional phenotype. Dual targeting of PD-1 + LAG3 or PD-1 + TIGIT partially restored their function in mice with MM. We identify phenotypic hallmarks of large intratumoral T cell clones, and demonstrate that the CD27− and CD27+ T cell ratio, measured by flow cytometry, may serve as a surrogate of clonal T cell expansions and an independent prognostic factor in 543 patients with MM treated with lenalidomide-based treatment combinations.This work was supported by grants from the Instituto de Salud Carlos III/Subdireccion General de Investigacion Sanitaria and co-financed by FEDER funds (CB16/12/00233, CB16/12/00369, PI17/01243, PI19/00818 and PI20/00048), and together with Fundación Científica de la Asociación Española Contra el Cáncer (FCAECC) for iMMunocell Transcan-2 (AC17/00101), FCAECC Predoctoral Grant Junta Provincial Navarra, the Cancer Research UK (C355/A26819), FCAECC and Italian Association for Cancer Research (AIRC) under the Accelerator Award Program (EDITOR), 2017 Multiple Myeloma Research Foundation Immunotherapy Networks of Excellence, Black Swan Research Initiative of the International Myeloma Foundation, European Hematology Association nonclinical advanced research grant (3680644), European Research Council 2015 Starting Grant (MYELOMANEXT grant 680200), the Cancer Research Innovation in Science Cancer Foundation (PR_EX_2020-02), the Leukemia Lymphoma Society, unrestricted grants from Bristol-Myers Squibb/Celgene and Takeda, Roche imCORE program (NAV-4 and NAV-15), Fondazione Regionale per la Ricerca Biomedica (Regione Lombardia) (Project ID 065 JTC 2016), ERA-NET TRANSCAN-2, and by My First AIRC Grant 2020 (n. 24534, 2021/2026), and by the Riney Family Multiple Myeloma Research Program Fund
Lenalidomide and dexamethasone with or without clarithromycin in patients with multiple myeloma ineligible for autologous transplant: a randomized trial
Mieloma; Assajos controlats aleatorisMieloma; Ensayos controlados aleatoriosMyeloma; Randomized controlled trialsAlthough case-control analyses have suggested an additive value with the association of clarithromycin to continuous lenalidomide and dexamethasone (Rd), there are not phase III trials confirming these results. In this phase III trial, 286 patients with MM ineligible for ASCT received Rd with or without clarithromycin until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). With a median follow-up of 19 months (range, 0–54), no significant differences in the median PFS were observed between the two arms (C-Rd 23 months, Rd 29 months; HR 0.783, p = 0.14), despite a higher rate of complete response (CR) or better in the C-Rd group (22.6% vs 14.4%, p = 0.048). The most common G3–4 adverse events were neutropenia [12% vs 19%] and infections [30% vs 25%], similar between the two arms; however, the percentage of toxic deaths was higher in the C-Rd group (36/50 [72%] vs 22/40 [55%], p = 0.09). The addition of clarithromycin to Rd in untreated transplant ineligible MM patients does not improve PFS despite increasing the ≥CR rate due to the higher number of toxic deaths in the C-Rd arm. Side effects related to overexposure to steroids due to its delayed clearance induced by clarithromycin in this elderly population could explain these results. The trial was registered in clinicaltrials.gov with the name GEM-CLARIDEX: Ld vs BiRd and with the following identifier NCT02575144. The full trial protocol can be accessed from ClinicalTrials.gov.

Novel Therapeutic Approaches to Prevent Atherothrombotic Ischemic Stroke in Patients with Carotid Atherosclerosis
Atherothrombotic stroke represents approximately 20% of all ischemic strokes. It is caused by large-artery atherosclerosis, mostly in the internal carotid artery, and it is associated with a high risk of early recurrence. After an ischemic stroke, tissue plasminogen activator is used in clinical practice, although it is not possible in all patients. In severe clinical situations, such as high carotid stenosis (≥70%), revascularization by carotid endarterectomy or by stent placement is carried out to avoid recurrences. In stroke prevention, the pharmacological recommendations are based on antithrombotic, lipid-lowering, and antihypertensive therapy. Inflammation is a promising target in stroke prevention, particularly in ischemic strokes associated with atherosclerosis. However, the use of anti-inflammatory strategies has been scarcely studied. No clinical trials are clearly successful and most preclinical studies are focused on protection after a stroke. The present review describes novel therapies addressed to counteract inflammation in the prevention of the first-ever or recurrent stroke. The putative clinical use of broad-spectrum and specific anti-inflammatory drugs, such as monoclonal antibodies and microRNAs (miRNAs) as regulators of atherosclerosis, will be outlined. Further studies are necessary to ascertain which patients may benefit from anti-inflammatory agents and how
Presence of Ceramidase Activity in Electronegative LDL
Electronegative low-density lipoprotein (LDL(−)) is a minor modified fraction of human plasma LDL with several atherogenic properties. Among them is increased bioactive lipid mediator content, such as lysophosphatidylcholine (LPC), non-esterified fatty acids (NEFA), ceramide (Cer), and sphingosine (Sph), which are related to the presence of some phospholipolytic activities, including platelet-activating factor acetylhydrolase (PAF-AH), phospholipase C (PLC), and sphingomyelinase (SMase), in LDL(−). However, these enzymes' activities do not explain the increased Sph content, which typically derives from Cer degradation. In the present study, we analyzed the putative presence of ceramidase (CDase) activity, which could explain the increased Sph content. Thin layer chromatography (TLC) and lipidomic analysis showed that Cer, Sph, and NEFA spontaneously increased in LDL(−) incubated alone at 37 °C, in contrast with native LDL(+). An inhibitor of neutral CDase prevented the formation of Sph and, in turn, increased Cer content in LDL(−). In addition, LDL(−) efficiently degraded fluorescently labeled Cer (NBD-Cer) to form Sph and NEFA. These observations defend the existence of the CDase-like activity's association with LDL(−). However, neither the proteomic analysis nor the Western blot detected the presence of an enzyme with known CDase activity. Further studies are thus warranted to define the origin of the CDase-like activity detected in LDL(−)

Impact of prior lenalidomide or proteasome inhibitor exposure on the effectiveness of ixazomib–lenalidomide–dexamethasone for relapsed/refractory multiple myeloma: A pooled analysis from the INSURE study
Objectives: To characterize the impact of prior exposure and refractoriness to lenalidomide or proteasome inhibitors (PIs) on the effectiveness and safety of ixazomib–lenalidomide–dexamethasone (IRd) in relapsed/refractory multiple myeloma (RRMM). Methods: INSURE is a pooled analysis of adult RRMM patients who had received IRd in ≥2 line of therapy from three studies: INSIGHT MM, UVEA‐IXA, and REMIX. Results: Overall, 391/100/68 were lenalidomide‐naïve/−exposed/−refractory and 37/411/110 were PI‐naïve/−exposed/−refractory. Median duration of therapy (DOT) was 15.3/15.6/4.7 months and median progression‐free survival (PFS) was 21.6/25.8/5.6 months in lenalidomide‐naïve/exposed/refractory patients. Median DOT and PFS in PI‐naïve/exposed/refractory patients were 20.4/15.2/6.9 months and not reached/19.8/11.4 months, respectively. The proportion of lenalidomide‐naïve/exposed/refractory patients in INSIGHT and UVEA‐IXA who discontinued a study drug due to adverse events (AEs) was ixazomib, 31.6/28.2/28.0% and 18.6/6.7/10.5%; lenalidomide, 21.9/28.2/16.0% and 16.1/6.7/10.5%; dexamethasone, 18.4/20.5/16.0% and 10.6/0/10.5%, respectively. The proportion of PI‐naïve/exposed/refractory patients in INSIGHT and UVEA‐IXA who discontinued a study drug due to AEs was: ixazomib, 44.4/28.8/27.8% and 22.2/16.7/15.7%; lenalidomide, 33.3/22.0/19.4% and 16.7/15.9/11.8%; dexamethasone, 33.3/17.4/16.7% and 16.7/9.5/7.8%, respectively. REMIX AE discontinuation rates were unavailable. Conclusion: IRd appeared to be effective in RRMM patients in routine clinical practice regardless of prior lenalidomide or PI exposure, with better outcomes seen in lenalidomide‐ and/or PI‐nonrefractory versus refractory patients
Immunophenotype of normal vs. myeloma plasma cells: Toward antibody panel specifications for MRD detection in multiple myeloma
In recent years, several studies on large series of multiple myeloma (MM) patients have demonstrated the clinical utility of flow cytometry monitoring of minimal residual disease (flow-MRD) in bone marrow (BM), for improved assessment of response to therapy and prognostication. However, disturbing levels of variability exist regarding the specific protocols and antibody panels used in individual laboratories. Overall, consensus exists about the utility of combined assessment of CD38 and CD138 for the identification of BM plasma cells (PC); in contrast, more heterogeneous lists of markers are used to further distinguish between normal/reactive PCs and myeloma PCs in the MRD settings. Among the later markers, CD19, CD45, CD27, and CD81, together with CD56, CD117, CD200, and CD307, have emerged as particularly informative; however, no single marker provides enough specificity for clear discrimination between clonal PCs and normal PCs. Accordingly, multivariate analyses of single PCs from large series of normal/reactive vs. myeloma BM samples have shown that combined assessment of CD138 and CD38, together with CD45, CD19, CD56, CD27, CD81, and CD117 would be ideally suited for MRD monitoring in virtually every MM patient. However, the specific antibody clones, fluorochrome conjugates and sources of the individual markers determines its optimal (vs. suboptimal or poor) performance in an eight-color staining. Assessment of clonality, via additional cytoplasmic immunoglobulin (CyIg) κ vs. CyIgλ evaluation, may contribute to further establish the normal/reactive vs. clonal nature of small suspicious PC populations at high sensitivity levels, provided that enough cells are evaluatedGrant sponsor: Red Tematica de Investigacion Cooperativa en Cancer (RTICC) of the Instituto de Salud Carlos III (Ministry of Economy and Competitivity, Madrid, Spain) – FEDER; Grant number: RD12/0036/0048; Grant sponsors: EuroFlow Consortium; the International Myeloma Foundation-Black Swan Research Initiative.Peer Reviewe
