Leucine zipper-based immunomagnetic purification of CAR T cells displaying multiple receptors.

Resistance to chimaeric antigen receptor (CAR) T cell therapy develops through multiple mechanisms, most notably antigen loss and tumour-induced immune suppression. It has been suggested that T cells expressing multiple CARs may overcome the resistance of tumours and that T cells expressing receptors that switch inhibitory immune-checkpoint signals into costimulatory signals may enhance the activity of the T cells in the tumour microenvironment. However, engineering multiple features into a single T cell product is difficult because of the transgene-packaging constraints of current gene-delivery vectors.

Phase II Trial of Nivolumab Plus Doxorubicin, Vinblastine, Dacarbazine as Frontline Therapy in Older Adults With Hodgkin Lymphoma.

Purpose: We conducted a phase I/II study evaluating nivolumab plus doxorubicin, vinblastine, dacarbazine (N-AVD) as frontline therapy for treatment-naïve older adults (OA) with classical Hodgkin lymphoma (cHL; ClinicalTrials.gov identifier: NCT03033914).

Methods: Patients age ≥60 years with newly diagnosed, any stage, cHL were treated with six cycles of AVD at standard doses plus nivolumab 240 mg intravenously once every 2 weeks (on days 1 and 15) of each cycle.

Predictors and implications of renal injury after CD19 chimeric antigen receptor T-cell therapy.

Chimeric Antigen Receptor (CAR) T cells targeting CD19 induce durable remissions in patients with relapsed or refractory non-Hodgkin lymphoma (NHL), but many patients experience treatmentrelated toxicity. Cytokine release syndrome and immune effector cell-associated neurologic syndrome are extensively characterized. However, limited data exist on the burden, predictors, and implications of acute kidney injury (AKI) after CAR T cell therapy.

Cancer cachexia and weight loss before CAR T-cell therapy for lymphoma are independently associated with poor outcomes.

Chimeric antigen receptor (CAR) T-cell therapy has transformed the care of lymphoma, yet many patients relapse. Several prognostic markers have been associated with CAR T-cell outcomes, such as tumor burden, response to bridging chemotherapy, and laboratory parameters at the time of lymphodepletion or infusion. The effect of cancer cachexia and weight loss before CAR T cells on toxicity and outcomes is not well understood.

A Peer Support Intervention in Patients With Hematologic Malignancies Undergoing Hematopoietic Stem Cell Transplantation (HSCT): The STEPP Proof-of-Concept Trial.

Although peer support interventions are associated with improved patient-reported outcomes in diverse cancer populations, structured peer support programs tailored to the needs of patients undergoing hematopoietic stem cell transplantation (HSCT) are lacking. This single-arm, proof-of-concept trial aimed to refine the Supporting Transplant Experiences with Peer Program (STEPP), a structured, five-session, manualized, phone-delivered peer support intervention for patients undergoing HSCT, informed by qualitative feedback from patients. Adult patients with hematologic malignancies scheduled to undergo allogeneic or autologous HSCT were eligible to participate in the study approximately two weeks prior to their HSCT hospitalization.

CNS bridging radiotherapy achieves rapid cytoreduction before CAR T-cell therapy for aggressive B-cell lymphomas.

Chimeric antigen receptor (CAR) T-cell therapy (CART) for central nervous system lymphoma (CNSL) is a promising strategy, yet responses are frequently not durable. Bridging radiotherapy (BRT) is used for extracranial lymphoma in which it can improve CART outcomes through cytoreduction of high-risk lesions. We hypothesized that BRT would achieve similar, significant cytoreduction before CART for CNSL (CNS-BRT).

IL-18-secreting multiantigen targeting CAR T cells eliminate antigen-low myeloma in an immunocompetent mouse model.

Multiple myeloma is a plasma cell malignancy that is currently incurable with conventional therapies. Following the success of CD19-targeted chimeric antigen receptor (CAR) T cells in leukemia and lymphoma, CAR T cells targeting B-cell maturation antigen (BCMA) more recently demonstrated impressive activity in relapsed and refractory myeloma patients. However, BCMA-directed therapy can fail due to weak expression of BCMA on myeloma cells, suggesting that novel approaches to better address this antigen-low disease may improve patient outcomes.

Annual Meeting Content Analysis: Leveraging Annual Meetings to Promote Diversity, Equity, Inclusion, and Belonging in the Academy of Consultation-Liaison Psychiatry.

Background: There is an increasing need to promote diversity, equity, and inclusion (DEI) in all aspects of academic medicine, including through continuing medical education. Although professional medical organizations' annual meetings play an instrumental role in continuing medical education for physicians, there are no studies describing DEI content in the annual meeting programming of professional medical organizations, including the Academy of Consultation-Liaison Psychiatry (ACLP), the primary professional organization for consultation-liaison psychiatrists.

Objective: To examine the ACLP annual meeting titles using Content Analysis.

Gratitude, optimism, and satisfaction with life and patient-reported outcomes in patients undergoing hematopoietic stem cell transplantation.

Objective: Associations between positive psychological well-being (PPWB) and patient-reported outcomes (PROs, e.g., quality of life [QOL]) have yet to be studied extensively in patients with hematologic malignancies who are allogeneic hematopoietic stem cell transplant (HSCT) survivors, despite substantial evidence that PPWB impacts PROs of other medical populations.

A Positive Psychology Intervention for Caregivers of Hematopoietic Stem Cell Transplantation Survivors (PATH-C): Initial Testing and Single-Arm Pilot Trial.

Caregivers of patients with hematologic malignancies undergoing allogeneic hematopoietic stem cell transplantation (HSCT) play a crucial role in supporting their loved ones through physical, emotional, and practical challenges. This role has been associated with high levels of psychological distress and low levels of positive psychological well-being (PPWB). Positive psychology interventions for caregivers in other disease groups (eg, breast cancer) have been associated with improved outcomes.

Associations between Health-Related Use of Social Media and Positive Lifestyle Behaviors: Findings from a Representative Sample of US Adult Smokers.

: Cigarette smokers have elevated cardiovascular risk factors, which contributes significantly to mortality. Although social media is a potential avenue to deliver smoking interventions, its role in health promotion among smokers remains relatively unexplored.: To examine the uptake and impact of health-related social media use in cigarette smokers.

CAR T-cell therapy in large B cell lymphoma.

CD19-targeted chimeric antigen receptor (CAR) T-cells have revolutionized the treatment of lymphoid malignancies, including large B cell lymphoma (LBCL). Following seminal early phase multicenter clinical trials published between 2017 and 2020, three CD19-CAR T-cell products received FDA and EMA approval designations in lymphoma in the third-line setting, paving the way for follow-up studies in the second-line. Meanwhile, investigations into the applications of CAR T-cell therapy have further broadened to treating high-risk patients even prior to completion of first-line conventional chemo-immunotherapy.

Hypothalamic TrkB.FL overexpression improves metabolic outcomes in the BTBR mouse model of autism.

BTBR T+ Itpr3tf/J (BTBR) mice are used as a model of autism spectrum disorder (ASD), displaying similar behavioral and physiological deficits observed in patients with ASD. Our recent study found that implementation of an enriched environment (EE) in BTBR mice improved metabolic and behavioral outcomes. Brain-derived neurotrophic factor (Bdnf) and its receptor tropomyosin kinase receptor B (Ntrk2) were upregulated in the hypothalamus, hippocampus, and amygdala by implementing EE in BTBR mice, suggesting that BDNF-TrkB signaling plays a role in the EE-BTBR phenotype.

Effect of Vitamin D Supplementation on Outcomes in People With Early Psychosis: The DFEND Randomized Clinical Trial.

Importance: People with psychotic disorders have an increased risk of vitamin D deficiency, which is evident during first-episode psychosis (FEP) and associated with unfavorable mental and physical health outcomes.

Objective: To examine whether vitamin D supplementation contributes to improved clinical outcomes in FEP.

Design, Setting, And Participants: This multisite, double-blind, placebo-controlled, parallel-group randomized clinical trial from the UK examined adults 18 to 65 years of age within 3 years of a first presentation with a functional psychotic disorder who had no contraindication to vitamin D supplementation.

Applications of Artificial Intelligence in Drug Design: Opportunities and Challenges.

Artificial intelligence (AI) has undergone rapid development in recent years and has been successfully applied to real-world problems such as drug design. In this chapter, we review recent applications of AI to problems in drug design including virtual screening, computer-aided synthesis planning, and de novo molecule generation, with a focus on the limitations of the application of AI therein and opportunities for improvement. Furthermore, we discuss the broader challenges imposed by AI in translating theoretical practice to real-world drug design; including quantifying prediction uncertainty and explaining model behavior.

A multicenter phase 1 study of nivolumab for relapsed hematologic malignancies after allogeneic transplantation.

Programmed cell death-1 (PD-1)/programmed death ligand-1 blockade may potentially augment graft-vs-tumor effects following allogeneic hematopoietic cell transplantation (alloHCT), but retrospective studies of anti-PD-1 therapy reported substantial toxicity from graft-versus-host-disease (GVHD). Here, we report the results of a prospective clinical trial of PD-1 blockade for relapsed hematologic malignancies (HMs) after alloHCT (NCT01822509). The primary objective in this phase 1 multicenter, investigator-initiated study was to determine maximum tolerated dose and safety.

Vitamin D supplementation compared to placebo in people with First Episode psychosis - Neuroprotection Design (DFEND): a protocol for a randomised, double-blind, placebo-controlled, parallel-group trial.

Background: People experiencing their first episode of psychosis are often deficient in vitamin D. Observational studies have reported an association between low vitamin D concentrations and poorer subsequent health outcomes in psychosis. A vitamin D deficiency in neonates and children has been linked to a later increased risk of schizophrenia and psychotic-like experiences.

Identification of Racial Inequities in Access to Specialized Inpatient Heart Failure Care at an Academic Medical Center.

Background: Racial inequities for patients with heart failure (HF) have been widely documented. HF patients who receive cardiology care during a hospital admission have better outcomes. It is unknown whether there are differences in admission to a cardiology or general medicine service by race.

Environmental enrichment improves metabolic and behavioral health in the BTBR mouse model of autism.

BTBR T + Itpr3tf/J (BTBR) mice are an Autism Spectrum Disorder (ASD)-like model that exhibit behavioral and physiological deficits similar to those observed in patients with ASD. While behavioral therapy is a first line of treatment in ASD patients, comparable non-pharmacological treatments are less explored in murine models. Here, we administer a bio-behavioral intervention for BTBR mice by way of environmental enrichment (EE) - an experimental housing paradigm previously shown to improve systemic metabolism, learning/memory, anxious behavior, neurogenesis, locomotion, and immunocompetence in C57BL/6 mice.
