WT1-TCB-treated T cells exhibited higher cytotoxicity against primary AML cells than an HLA-A*02 RMF-specific T-cell clone. Combining WT1-TCB with the immunomodulatory drug lenalidomide further enhanced antibody-mediated T-cell cytotoxicity against primary AML cells (mean specific lysis on day 3-4 45.4±9.0% vs 70.8±8.3%; p=0.015; ±SEM; n=9-10). In vivo, WT1-TCB-treated humanized mice bearing SKM-1 tumors showed a significant and dose-dependent reduction in tumor growth. In summary, we show that WT1-TCB facilitates potent in vitro, ex vivo and in vivo killing of AML cell lines and primary AML cells; these results led to the initiation of a phase I trial in patients with r/r AML (NCT04580121).Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a severe adverse effect of ChAdOx1 nCoV-19 COVID-19 vaccine (Vaxzevria) and COVID-19 vaccine Janssen (Ad26.COV2.S), and associated with unusual thrombosis. VITT is caused by anti-platelet factor 4 (PF4) antibodies activating platelets through their FcgRIIa receptors. Antibodies activating platelets through FcgRIIa receptors have also been identified in COVID-19 patients. These findings raise concern that vaccination-induced antibodies against anti-SARS-CoV-2 spike protein cause thrombosis by cross-reacting with PF4. Immunogenic epitopes of PF4 and SARS-CoV-2 spike protein were compared using in-silico prediction tools and 3D-modelling. The SARS-CoV-2 spike protein and PF4 share at least one similar epitope. Reactivity of purified anti-PF4 antibodies from patients with VITT was tested against recombinant SARS-CoV-2 spike protein. However, none of the affinity-purified anti-PF4 antibodies from 14 VITT patients cross-reacted with SARS-CoV-2 spike protein. Sera from 222 PCR-confirmed COVID-19 patients from five European centers were tested by PF4/heparin ELISA and PF4-dependent platelet activation assays. We found anti-PF4 antibodies in 19 of 222 (8.6%) COVID-19 patient sera. However, only four showed weak to moderate platelet activation in the presence of PF4, and none of these patients developed thrombotic complications. Among 10 of 222 (4.5%) COVID-19 patients with thrombosis, none showed PF4-dependent platelet-activating antibodies. In conclusion, antibodies against PF4 induced by vaccination do not cross-react with the SARS-CoV-2 spike protein, indicating that the intended vaccine-induced immune response against SARS-CoV-2 spike protein is not the trigger of VITT. PF4-reactive antibodies found in COVID-19 patients of the present study were not associated with thrombotic complications.
Despite numerous examples of health policy transfer in Western health systems, the nature of such "inspired" reforms has received little detailed attention. The aim of this article is to apply and refine a specific theoretical angle for the analysis of these reforms, using the theoretical frameworks of transfer and translation.

The design is based on a comparative case study the introduction of disease management programs (DMPs) for diabetes in Germany in 2002 and in France in 2008, drawing on a literature review and semi-structured interviews.

In introducing its DMP, Germany chose and combined several components in a process of selective borrowing, while France opted for copying a specific foreign program and adapting it. Such differences in process are linked to distinct system structures, in particular the setup of health insurance and the representation of physicians. Further, the displayed versus actual degree of inspiration varied significantly, with a branding strategy in Germany (high display of foreign influence) and the inverse picture in France (high degree of actual inspiration).

This analysis has applied the dual perspective of transfer and translation. Both proved complementary and necessary, and translation appeared as a main determinant of implementation success.

Goal-directed behavior is elicited by introducing prior beliefs on the underlying generative model. In contrast to prior beliefs, which constrain all realizations of a random variable, we propose an alternative approach through chance constraints, which allow for a (typically small) probability of constraint violation, and demonstrate how such constraints can be used as intrinsic drivers for goal-directed behavior in ActInf. We illustrate how chance-constrained ActInf weights all imposed (prior) constraints on the generative model, allowing, for example, for a trade-off between robust control and empirical chance constraint violation. mTOR kinase assay Second, we interpret the proposed solution within a message passing framework. Interestingly, the message passing interpretation is not only relevant to the context of ActInf, but also provides a general-purpose approach that can account for chance constraints on graphical models. The chance constraint message updates can then be readily combined with other prederived message update rules without the need for custom derivations. The proposed chance-constrained message passing framework thus accelerates the search for workable models in general and can be used to complement message-passing formulations on generative neural models.
Professional deontology can be defined as a set of principles, values and rules of conduct to be applied in the exercise of functions and inherent to a given profession. Nephrology was one of the medical specialties most affected by the mismatch between the accelerated technological development and the ethical dilemmas resulting from it. Recently, the Brazilian Society of Nephrology (SBN) edited its code of conduct, which until then did not exist.

Qualitative study with content analysis of the chapters and articles of the SBN Code of Conduct, from the perspective of principlism bioethics.

The four moral principles of beneficence, non-maleficence, autonomy and justice were found asymmetrically throughout the document, with beneficence predominating over the others.

The SBN Code of Conduct predominantly expresses the ethical duties that an associate must comply with, but also restrictions on malfeasance, autonomy and justice, anchoring decision-making by managers and including the distribution of possible punishments. It is an unfinished document; therefore, it must be periodically revised, as expected, due to the rapid technological changes, as well as the need for constructive moderation in the relations of nephrologists with each other and, between them, with the Industry, as well as all the ethical consequences arising from these factors.

The patient's age, tumor size, lymph node status, histological type, histological grade, lymphovascular invasion, hormonal receptor status, human epidermal growth factor receptor 2 (Her2neu) expression, and Ki-67 labeling index for proliferation rate can help determine the appropriate management strategy in these patients. The authors conducted this descriptive retrospective study to assess the association of Ki-67 with clinicopathological parameters in a newly established institute. This may help guide treatment planning in developing countries. Methodology Patients diagnosed with primary breast cancer in our institute between January 2017 and March 2020 were included in this study. The clinicopathological prognostic factors were retrieved from the records. Results A total of 129 cases of core needle biopsy and mastectomy specimens were included in this study. The patient's mean age and median age were 47.41 and 47 years, respectively. Only 56 specimens of mastectomy were received. T2 (26/56) was the most common tumor size. Grading was done in 46 cases, and grade 2 (23/46) was the most common. Estrogen, progesterone, and Her2neu were positive in 65, 61, and 59 cases, respectively. Only estrogen receptor (ER) expression (p = 0.035) and Her2neu (p = 0.035) overexpression were significantly correlated with Ki-67. Conclusions Ki-67 expression was correlated with clinicopathological factors. Only ER expression and Her2neu overexpression were significantly associated with Ki-67. Hence, patients with high Ki-67 expression may have better responses to hormonal therapy and chemotherapy.We have recently demonstrated that the function of T follicular helper (Tfh) cells from lymph nodes (LN) of HIV-infected individuals is impaired. We found that these cells were unable to provide proper help to germinal center (GC)-B cells, as observed by altered and inefficient anti-HIV antibody response and premature death of memory B cells. The underlying molecular mechanisms of this dysfunction remain poorly defined. Herein, we have used a unique transcriptional approach to identify these molecular defects. We consequently determined the transcriptional profiles of LN GC-Tfh cells following their interactions with LN GC-B cells from HIV-infected and HIV-uninfected individuals, rather than analyzing resting ex-vivo GC-Tfh cells. We observed that proliferating GC-Tfh cells from HIV-infected subjects were transcriptionally different than their HIV-uninfected counterparts, and displayed a significant downregulation of immune- and GC-Tfh-associated pathways and genes. Our results strongly demonstrated that MAF (coding for the transcription factor c-Maf) and its upstream signaling pathway mediators (IL6R and STAT3) were significantly downregulated in HIV-infected subjects, which could contribute to the impaired GC-Tfh and GC-B cell functions reported during infection. We further showed that c-Maf function was associated with the adenosine pathway and that the signaling upstream c-Maf could be partially restored by adenosine deaminase -1 (ADA-1) supplementation. Overall, we identified a novel mechanism that contributes to GC-Tfh cell impairment during HIV infection. Understanding how GC-Tfh cell function is altered in HIV is crucial and could provide critical information about the mechanisms leading to the development and maintenance of effective anti-HIV antibodies.Cytokines made by macrophages play a critical role in determining the course of Legionella pneumophila infection. Prior murine-based modeling indicated that this cytokine response is initiated upon recognition of L. pneumophila by a subset of Toll-like receptors, namely TLR2, TLR5, and TLR9. Through the use of shRNA/siRNA knockdowns and subsequently CRISPR/Cas9 knockouts (KO), we determined that TRIF, an adaptor downstream of endosomal TLR3 and TLR4, is required for full cytokine secretion by human primary and cell-line macrophages. By characterizing a further set of TLR KO's in human U937 cells, we discerned that, contrary to the viewpoint garnered from murine-based studies, TLR3 and TLR4 (along with TLR2 and TLR5) are in fact vital to the macrophage response in the early stages of L. pneumophila infection. This conclusion was bolstered by showing that i) chemical inhibitors of TLR3 and TLR4 dampen the cytokine output of primary human macrophages and ii) transfection of TLR3 and TLR4 into HEK cells conferred an ability to sense L.
