BACKGROUND Mounting pressures on the healthcare system, such as budget constraints and new, costly health technologies reaching the market, have pushed payers and manufacturers to engage in managed entry agreements (MEAs) to address uncertainty and facilitate market access. OBJECTIVES This study was conducted to illustrate the current landscape of MEAs in Europe and to analyze the main hurdles they face in implementation, providing a policy perspective. METHODS We conducted a health policy analysis based on a literature review and described the emergence, classification, current use, and implementation obstacles of MEAs in Europe. RESULTS Throughout Europe, uncertainty and high prices of health technologies have pushed stakeholders towards MEAs. Ipatasertib Two main types of MEAs were applied heavily, finance-based agreements (FBAs) and performance-based agreements, including individual performance-based agreements and coverage with evidence development (CED). Service-based agreements have not been as heavily considered so far, yet are increasingly used. Many European countries are turning to CEDs to address uncertainty and facilitate market access while negotiating the pricing and reimbursement rates of products. Despite the interest in CEDs, European countries have moved toward FBAs due to the complexities and burdens associated with PBAs. CONCLUSIONS Ultimately, in Europe, with the exception of Italy, where MEAs have proven to be inefficient, MEAs are predominantly FBAs dedicated to addressing cost containment from payers' perspective and external reference pricing from the manufacturers' perspective. It has been speculated that MEAs will disappear in the medium-term as they are counterproductive for extending patient access and emergence of innovation. To inform value-based decision making and allow early access to innovative medicines, CEDs should be revisited. Steep increases in prices and spending on prescription drugs in the United States have triggered public outrage and questions over their value. Value-based pricing has emerged as a preferred alternative to prices determined by what the market will bear. In response, manufacturers and health plans have begun to publicize their efforts to engage in outcomes-based contracts and long-term financing agreements, which they describe as value-based. Nevertheless, both contracting approaches perpetuate existing distortions in the financial incentives of supply chain and prescribing intermediaries, and fail to realign the prices of drugs to their value to patients, the healthcare system, or society. This commentary describes the challenges of managing drugs according to their value, and describes several alternatives that promise greater impact than contracting strategies. In response to rising healthcare costs, value-based arrangements (VBAs) have emerged as a mechanism for transforming how we pay for high-cost therapies. As we think about how VBAs fit into the larger effort of the United States healthcare system to transition to value-based payment, it is important to consider the strengths and limitations associated with this model and to set appropriate expectations for what VBAs can realistically achieve. For example, for VBAs to meaningfully affect overall healthcare spending, there needs to be a sufficient number of products that meet the ideal criteria for a value-based contract. These products also need to represent a meaningful share of healthcare spending, and the VBA contracts need to be designed with enough financial risk to actually influence spending. Although there are limited data about the components of current contracts (eg, how much financial risk is involved, product and class specifications), VBAs will likely not be a singular solution for improving healthcare cost containment. Instead, VBAs offer an opportunity for the US healthcare system to achieve higher value for dollars spent when implemented in combination with other value-based payment mechanisms and policies that disincentivize low-value care. The International Society for Pharmacoeconomics and Outcomes Research (ISPOR)'s "Good Practices Task Force" reports are highly cited, multistakeholder perspective expert guidance reports that reflect international standards for health economics and outcomes research (HEOR) and their use in healthcare decision making. In this report, we discuss the criteria, development, and evaluation/consensus review and approval process for initiating a task force. The rationale for a task force must include a justification, including why this good practice guidance is important and its potential impact on the scientific community. The criteria include (1) necessity (why is this task force required?); (2) a methodology-oriented focus (focus on research methods, approaches, analysis, interpretation, and dissemination); (3) relevance (to ISPOR's mission and its members); (4) durability over time; (5) broad applicability; and 6) an evidence-based approach. In addition, the proposal must be a priority specifically for ISPOR. These reports are valuable to researchers, academics, students, health technology assessors, medical technology developers and service providers, those working in other commercial entities, regulators, and payers. These stakeholder perspectives are represented in task force membership to ensure the report's overall usefulness and relevance to the global ISPOR membership. We hope that this discussion will bring transparency to the process of initiating, approving, and producing these task force reports and encourage participation from a diverse range of experts within and outside ISPOR. Management of hematologic malignancies in older patients is complex and, with recent and anticipated trends in demographics, increasingly common. As a large, nationally integrated medical system the Veterans Affairs has the potential to lead in research to benefit these patients. In this review we describe the evolving treatment paradigms of hematologic malignancies and how they are best fit with older patients through comprehensive evaluation of key vulnerabilities. We also discuss optimization of supportive care and navigation services to target identified risks and challenges aimed at ameliorating the patient's burden of cancer and treatment. Lastly, we discuss opportunities in design of prospective clinical trials to better align with real-world cases, thereby expanding enrollment of and applicability to older patients with hematologic malignancies.

They are generated in a fundamental cellular restructuring process from naive B cells upon contact with antigen. This outstanding process is guided and controlled by a complex transcriptional network accompanied by a fascinating morphological metamorphosis, governed by the combined action of Blimp-1, Xbp-1 and IRF-4. The survival of plasma cells requires the intimate interaction with a specific microenvironment, consisting of stromal cells and cells of hematopoietic origin. Cell-cell contacts, cytokines and availability of metabolites such as glucose and amino acids modulate the survival abilities of plasma cells in their niches. Moreover, plasma cells have been shown to regulate immune responses by releasing cytokines. Furthermore, plasma cells are central players in autoimmune diseases and malignant transformation of plasma cells can result in the generation of multiple myeloma. Hence, the development of sophisticated strategies to deplete autoreactive plasma cells and myeloma cells represents a challenge for current and future research. © 2020 Elsevier Inc.

Disruption of the delicate balance between beneficial and pathogenic commensals, known as dysbiosis, contributes to a variety of chronic immunologic and metabolic diseases. Complicating this paradigm are bacterial strains that can operate paradoxically both as instigators and attenuators of inflammatory responses, depending on host background. Here, we review the role of several strains in the genus Lactobacillus within the context of autoimmune and other chronic disorders with a predominant focus on L. reuteri. While strains within this species have been shown to provide immune health benefits, they have also been demonstrated to act as a pathobiont in autoimmune-prone hosts. Beneficial functions in healthy hosts include competing with pathogenic microbes, promoting regulatory T cell development, and protecting the integrity of the gut barrier. On the other hand, certain strains can also break through a dysfunctional gut barrier, colonize internal tissues such as the spleen or liver and promote inflammatory responses in host tissues that lead to autoimmune disease. This review summarizes the manifold roles that these commensals play in the context of health and disease. © 2020 Elsevier Inc.

Our understanding of the role of PI3Kδ in the immune system comes primarily from mice, and especially from the consequences of pharmacological inhibition of PI3Kδ in mouse models of human disease as well as the consequences of genetic manipulation, resulting in hyperactivation or loss of PI3Kδ function. In case of humans, in vitro studies with PI3Kδ-specific inhibitors, the consequences of treatment of hematologic malignancies with the PI3Kδ-specific inhibitor idelalisib and primary immunodeficiency disorders due to germline variants hyper- or underactivating PI3Kδ provide most of our knowledge on the role of PI3Kδ in immunity and immune regulation. In this review, we summarize the physiological and pathophysiological roles of PI3Kδ in the human immune system, focusing on immunodeficiency due to defects in PI3Kδ signaling and especially on the recently reported cases with mutations resulting in loss of PI3Kδ activity. © 2020 Elsevier Inc.

NK cells are distinct from B and T lymphocytes in that they become activated through a series of broadly expressed germ line encoded activating and inhibitory receptors or through the actions of inflammatory cytokines. They are the founding member of the innate lymphoid cell family, which mirror the functions of T lymphocytes, with NK cells being the innate counterpart to CD8 T lymphocytes. Despite the functional relationship between NK cells and CD8 T cells, the mechanisms controlling their specification, differentiation and maturation are distinct, with NK cells emerging from multipotent lymphoid progenitors in the bone marrow under the control of a unique transcriptional program. Over the past few years, substantial progress has been made in understanding the developmental pathways and the factors involved in generating mature and functional NK cells.
