Article Abstract
Chimeric antigen receptor (CAR-) T cells are revolutionizing cancer treatment, as a direct result of their clinical impact on the treatment of hematological malignancies. However for solid tumors, CAR-T cell therapeutic efficacy remains limited, primarily due to the complex immunosuppressive tumor microenvironment, inefficient access to tumor cells and poor persistence of the killer cells. In this in vitro study, an injectable, gelatin-based micro-hydrogel system that can encapsulate and deliver effective CAR-T therapy is investigated. CAR-T cells targeting TAG-72, encapsulated in these microgels possessed high viability (> 87%) after 7 days, equivalent to those grown under normal expansion conditions, with retention of the T cell phenotype and functionality. Microgel recovered CAR-T cells demonstrated potent on-target cytotoxicity against human ovarian cancer in vitro and on three-dimensional tumor spheroids, by completely eliminating tumor cells. The gelatin-based micro-hydrogels have the potential to serve as carrier systems to augment CAR-T immunotherapeutic treatment of solid tumors.
Background: A central goal of implementation science is to generate insights that allow evidence-based practices to be successfully applied across diverse settings. However, challenges often arise in preserving programs' effectiveness outside the context of their intervention development. We propose that qualitative data can inform generalizability via elucidating mechanisms of an intervention.

Background: Pancreatic ductal adenocarcinoma (PDAC) requires innovative therapeutic strategies to counteract its progression and metastatic potential. Since the majority of patients are diagnosed with advanced metastatic disease, treatment strategies targeting not only the primary tumor but also metastatic lesions are needed. Tumor-Associated Macrophages (TAMs) have emerged as central players, significantly influencing PDAC progression and metastasis.
Background: This study aims to determine the impact of a childbirth educational intervention, based on empowerment theory, on childbirth experience and empowerment in women with fetal occiput posterior and occiput transverse malpositions.
Methods: A randomized controlled trial was conducted from February 2022 to December 2022 involving pregnant women with fetal occiput posterior and occiput transverse malpositions. Eligible women were randomly assigned to either the control or study group.
Background: The COVID-19 pandemic exposed critical gaps in health system preparedness. This study, guided by a critical ecological model, examines the experiences of primary health and community services in Aotearoa New Zealand during the pandemic, focusing on their response to older people and their unpaid caregivers. The study aims to identify effective strategies for health system resilience.
