Development of the Crisis and Emergency Intervention Skills Scale (CEISS) and an analysis of its psychometric properties.

Emergency psychology is a branch of psychology that, although it began several years ago due to dramatic events around the world, is increasingly being established in the day-to-day work of the emergency department. Due to the very specific nature of this type of intervention, it is essential that, in addition to proper training and experience, emergency psychologists have a series of competencies. In this study, we developed a questionnaire, the Crisis and Emergency Intervention Skills Scale (CEISS), ad hoc for this research, and we determined the relationship of the CEISS score with the most relevant competencies.

Multidimensional profiling of cancer microenvironments in FFPE tissues by imaging mass cytometry.

In recent years, significant advancements have been achieved in the development of multiplex imaging methodologies for immunophenotyping, enabling a comprehensive characterization of the complexity of tumor microenvironments. Imaging mass cytometry combines the detection of over 40 cellular targets with spatial information, enabling the identification of not only which cells are present in a tissue but also their localization relative to each other. Here, we present an easy-to-implement imaging mass cytometry workflow that ranges from antibody selection and testing to running a full panel.

Enabling next-generation engineered TCR-T therapies based on high-throughput TCR discovery from diagnostic tumor biopsies.

Adoptive cell therapy with tumor-infiltrating lymphocytes (TIL) can mediate tumor regression, including complete and durable responses, in a range of solid cancers, most notably in melanoma. However, its wider application and efficacy has been restricted by the limited accessibility, proliferative capacity and effector function of tumor-specific TIL. Here, we develop a platform for the efficient identification of tumor-specific TCR genes from diagnostic tumor biopsies, including core-needle biopsies frozen in a non-viable format, to enable engineered T cell therapy.
