    Abstract The analysis of multidimensional time-varying datasets faces challenges, notably regarding the representation of the data and the visualization of temporal variations. We propose an extension of the well-known Space-Time Cube (STC) visualization technique in order to visualize time-varying 3D spatial data, taking advantage of the interaction capabilities of Virtual Reality (VR). First, we propose the Space-Time Hypercube (STH) as an abstraction for 3D temporal data, extended from the STC concept. Second, through the example of embryo development imaging dataset, we detail the construction and visualization of a STC based on a user-driven projection of the spatial and temporal information. This projection yields a 3D STC visualization, which can also encode additional numerical and categorical data. Additionally, we propose a set of tools allowing the user to filter and manipulate the 3D STC which benefits the visualization, exploration and interaction possibilities offered by VR. Finally, we evaluated the proposed visualization method in the context of 3D temporal cell imaging data analysis, through a user study (n = 5) reporting the feedback from five biologists. These domain experts also accompanied the application design as consultants, providing insights on how the STC visualization could be used for the exploration of complex 3D temporal morphogenesis data.

    Abstract We propose an extension of the well-known Space-Time Cube (STC) visualization technique in order to visualize time-varying 3D spatial data, taking advantage of the interaction capabilities of Virtual Reality (VR). The analysis of multidimensional time-varying datasets, which size grows as recording and simulating techniques advance, faces challenges on the representation and visualization of dense data, as well as on the study of temporal variations. First, we propose the Space-Time Hypercube (STH) as an abstraction for 3D temporal data, extended from the STC concept. Second, through the example of embryo development imaging dataset, we detail the construction and visualization of a STC based on a user-driven projection of the spatial and temporal information. This projection yields a 3D STC visualization, which can also encode additional numerical and categorical data. Additionally, we propose a set of tools allowing the user to filter and manipulate the 3D STC which benefits from the visualization, exploration and interaction possibilities offered by VR. Finally, we evaluated the proposed visualization method in the context of the visualization of spatio-temporal biological data. Several biology experts accompanied the application design to provide insight on how the STC visualization could be used to explore such data. We report a user study (n=12) using non-expert users performing a set of exploration and query tasks to evaluate the system.

  5. Book ; Online: Timeline Design Space for Immersive Exploration of Time-Varying Spatial 3D Data

    Abstract Timelines are common visualizations to represent and manipulate temporal data, from historical events storytelling to animation authoring. However, timeline visualizations rarely consider spatio-temporal 3D data (e.g. mesh or volumetric models) directly, which are typically explored using 3D visualizers only displaying one time-step at a time. In this paper, leveraging the increased workspace and 3D interaction capabilities of virtual reality, we propose to use timelines for the visualization of 3D temporal data to support exploration and analysis. First, we propose a timeline design space for 3D temporal data extending the timeline design space proposed by Brehmer et al. The proposed design space adapts the scale, layout and representation dimensions to account for the depth dimension and how 3D temporal data can be partitioned and structured. In our approach, an additional dimension is introduced, the support, which further characterizes the 3D dimension of the visualization. To complement the design space and the interaction capabilities of VR systems, we discuss the interaction methods required for the efficient visualization of 3D timelines. Then, to evaluate the benefits of 3D timelines, we conducted a formal evaluation with two main objectives: comparing the proposed visualization with a traditional visualization method; exploring how users interact with different 3D timeline designs. Our results showed that time-related tasks can be achieved more comfortably using timelines, and more efficiently for specific tasks requiring the analysis of the surrounding temporal context. Though the comparison between the different timeline designs were inconclusive, participants reported a clear preference towards the timeline design that did not occupy the vertical space. Finally, we illustrate the use of the 3D timelines to a real use-case on the analysis of biological 3D temporal datasets.

    Abstract Background: Recurrence after Cytomegalovirus (CMV) infection in heart transplant recipients is difficult to predict, in spite of its high incidence. Secondary prophylaxis could reduce this burden; however, its duration remains unestablished. We evaluated the QuantiFERON®-CMV test to see if it could predict CMV recurrence and help optimize the duration of secondary prophylaxis.
    Methods: This observational retrospective single center study included all heart transplant recipients who developed CMV infection between 2019 and 2021, with the CD8+ T-cell-mediated CMV immunity QuantiFERON®-CMV test assessed at the time of (val)ganciclovir curative treatment completion. The main outcomes were CMV recurrence and duration of secondary prophylaxis. Secondary outcomes included immunosuppressive regimen, rejection, lymphocyte count, CMV viral load, infection type, and duration as possible confounding factors for recurrence.
    Results: Among the 15 patients included, five (33%) experienced recurrence, of whom three (60%) had a positive QuantiFERON®-CMV test. The duration of secondary prophylaxis was similar regardless of QF-CMV positivity. No confounding factor was significantly associated with CMV recurrence; however, it occurred in only 1/7 (14%) of the patients receiving an everolimus-containing immunosuppressive regimen.
    Conclusion: In the population of heart transplant recipients, most of whom received ATG-based induction, the QuantiFERON®-CMV assay may not accurately predict CMV recurrence and would have not helped refining the duration of secondary prophylaxis in our patients. Other cell-mediated immunity tests and strategies in this specific population, including everolimus-containing regimens, may help predict and manage CMV recurrence.

    Abstract Trauma remains a leading cause of death worldwide. Hemorrhagic shock and direct injury to vital organs are responsible for early mortality whereas most delayed deaths are secondary to complex pathophysiological processes. These processes result from imbalanced systemic reactions to the multiple aggressions associated with trauma. Trauma results in the uncontrolled local and systemic release of endogenous mediators acting as danger signals [damage-associated molecular patterns (DAMPs)]. Their recognition by the innate immune system triggers a pro-inflammatory immune response paradoxically associated with concomitant immunosuppression. These responses, ranging in intensity from inappropriate to overwhelming, promote the propagation of injuries to remote organs, leading to multiple organ failure and death. Some of the numerous DAMPs released after trauma trigger the assembly of intracellular multiprotein complexes named inflammasomes. Once activated by a ligand, inflammasomes lead to the activation of a caspase. Activated caspases allow the release of mature forms of interleukin-1β and interleukin-18 and trigger a specific pro-inflammatory cell death termed pyroptosis. Accumulating data suggest that inflammasomes, mainly NLRP3, NLRP1, and AIM2, are involved in the generation of tissue damage and immune dysfunction after trauma. Following trauma-induced DAMP(s) recognition, inflammasomes participate in multiple ways in the development of exaggerated systemic and organ-specific inflammatory response, contributing to organ damage. Inflammasomes are involved in the innate responses to traumatic brain injury and contribute to the development of acute respiratory distress syndrome. Inflammasomes may also play a role in post-trauma immunosuppression mediated by dysregulated monocyte functions. Characterizing the involvement of inflammasomes in the pathogenesis of post-trauma syndrome is a key issue as they may be potential therapeutic targets. This review summarizes the current knowledge on the roles of inflammasomes in trauma.
