RESUMO

OBJECTIVE: The aim of this project was to develop and align an inpatient psychiatric safety event taxonomy that would blend well-established safety events with psychiatry-specific concerns. METHODS: A hybrid inductive-deductive thematic analysis was used to generate novel descriptive safety event categories for inpatient psychiatry and align these categories with an established taxonomic framework. In the inductive phase, an initial taxonomy was developed by describing the semantic subject and context of reported safety concerns. In the deductive phase, existing literature, national standards, and local content experts were used to align our taxonomy with the safety event measurement system at our institution. RESULTS: A total of 2291 events were extracted and 483 were analyzed. After thorough review, the data was divided into 4 domains: (1) Provision of care, (2) patient actions, (3) environment/equipment, and (4) safety culture. Each domain reflects a mutually exclusive typology of events and provides a parsimonious view of safety concerns in inpatient psychiatry. Each domain was further divided into categories, subcategories, and subcategory details. CONCLUSIONS: Safety events on inpatient psychiatric units are understudied and lack the measurement infrastructure to identify care processes that result in exposure to harm. We develop and align an inpatient psychiatric safety taxonomy based on real-world data, existing literature, and measurement standards. This taxonomy can be used by psychiatric hospitals to improve their patient safety measurement systems-and ultimately-the safety of their patients and communities.

RESUMO

SUMMARY: From climate change to hydraulic fracturing, and from drinking water safety to wildfires, environmental challenges are changing. The United States has made substantial environmental protection progress based on media-specific and single pollutant risk-based frameworks. However, today's environmental problems are increasingly complex and new scientific approaches and tools are needed to achieve sustainable solutions to protect the environment and public health. In this article, we present examples of today's environmental challenges and offer an integrated systems approach to address them. We provide a strategic framework and recommendations for advancing the application of science for protecting the environment and public health. We posit that addressing 21st century challenges requires transdisciplinary and systems approaches, new data sources, and stakeholder partnerships. To address these challenges, we outline a process driven by problem formulation with the following steps: a) formulate the problem holistically, b) gather and synthesize diverse information, c) develop and assess options, and d) implement sustainable solutions. This process will require new skills and education in systems science, with an emphasis on science translation. A systems-based approach can transcend media- and receptor-specific bounds, integrate diverse information, and recognize the inextricable link between ecology and human health.

RESUMO

Human skin equivalents (SEs) are popular three-dimensional (D) cell culture systems in fundamental and applied dermatology. They have been made to contain dendritic cells, but so far no study on the incorporation of potentially anti-inflammatory dermal macrophages has been performed. Here, we show that monocyte-derived dermal-type macrophages can be introduced into a rigid scaffold with dermal fibroblasts. They maintain their cell surface markers CD163, DC-SIGN/CD209 and HLA-DR, which discriminate them from monocytes and dendritic cells. They retain the ability to produce the anti-inflammatory cytokine IL-10 in response to lipopolysaccharide (LPS) and to phagocytose latex beads. We thus demonstrate the feasibility of creating macrophage-fibroblast 3D cultures as a first step towards generating SEs with dermal macrophages.

RESUMO

DC-SIGN is a C-type lectin of recognized importance in immunology and in the pathogenicity human pathogens. Monoclonal antibodies directed against DC-SIGN have been generated, but their systemic characterization for interfering with binding of the HIV-1 glycoprotein 120 has often been omitted. Moreover, so far, no anti-DC-SIGN monoclonal antibody has been described that recognizes its antigen after formalin fixation and paraffin embedding. In this study, we have generated new anti-DC-SIGN monoclonal antibodies using HeLa cells stably expressing DC-SIGN as immunogen. We have obtained 11 hybridoma clones producing antibodies that recognized DC-SIGN on monocyte-derived dendritic cells and on dermal-type macrophages. Seven monoclonal antibodies displayed a capacity to interfere with DC-SIGN binding to HIV-1 gp120. One recognized DC-SIGN on formalin-fixed dendritic cells and macrophages. Using this antibody we have obtained specific labelling of DC-SIGN and colocalisation with the dermal macrophage marker CD163 on human skin. The described monoclonal anti-human DC-SIGN antibodies will be of use to the scientific community to address fundamental immunology issues, in particular concerning macrophages and dendritic cells, and help elucidate infection events of pathogen targeting DC-SIGN as recognition receptor.
