Engaging youth in visualizing sustainable urban plans using geographic information systems coupled with computer visualization

In this chapter, we present results from an out-of-school time STEM (science, technology, engineering and mathematics) education program in the United States in which we engage urban youth in urban planning projects for sites in their neighbourhoods. In the field of urban planning today, it is nearly impossible to create any urban plan without the use of GIS technologies. In our work, youth have been using sophisticated GIS modelling technologies to create and evaluate different urban plans for particular areas within their own city. As part of their projects, youth visit a site to collect basic phsyical data, talk with residents, and identify the resources that are available to the neighbourhood. With that information in hand, the youth create different site designs using a software package, CommunityViz, and evaluate the economic and ecological impacts of their different designs, In doing this, youth learn about (1) the urban planning process; (2) GIS skills and the role that GIS plays in the urban planning process; and (3) evaluating and comparing the economic and ecological impact of different site designs

Time to definitive KPS deterioration (≥10-point KPS decrease from baseline) was calculated using the Kaplan–Meier method. A larger decrease from baseline (≥20 points) was investigated as a sensitivity analysis. A Cox proportional hazards model analyzed the effect of baseline factors (including treatment) potentially associated with time to definitive deterioration.Results: The two treatment arms had generally comparable time to any KPS deterioration, similar KPS at 3 and 6 months after randomization and at 1 month before disease progression, and no significant difference in time to definitive deterioration. Baseline KPS, neutrophil-to-lymphocyte ratio, age, liver metastases, and region had a significant effect on time to definitive KPS deterioration, but treatment arm did not.Conclusion: The increased survival observed with nab-paclitaxel plus gemcitabine was not associated with adverse effects on performance status.

A healthy lifestyle is positively associated with mental health and well-being and core markers in ageing

BACKGROUND: Studies often evaluate mental health and well-being in association with individual health behaviours although evaluating multiple health behaviours that co-occur in real life may reveal important insights into the overall association. Also, the underlying pathways of how lifestyle might affect our health are still under debate. Here, we studied the mediation of different health behaviours or lifestyle factors on mental health and its effect on core markers of ageing: telomere length (TL) and mitochondrial DNA content&nbsp;(mtDNAc). METHODS: In this study, 6054 adults from the 2018 Belgian Health Interview Survey (BHIS) were included. Mental health and well-being outcomes included psychological and severe psychological distress, vitality, life satisfaction, self-perceived health, depressive and generalised anxiety disorder and suicidal ideation. A lifestyle score integrating diet, physical activity, smoking status, alcohol consumption and BMI was created and validated. On a subset of 739 participants, leucocyte TL and mtDNAc were assessed using qPCR. Generalised linear mixed models were used while adjusting for a priori chosen&nbsp;covariates. RESULTS: The average age (SD) of the study population was 49.9 (17.5) years, and 48.8% were men. A one-point increment in the lifestyle score was associated with lower odds (ranging from 0.56 to 0.74) for all studied mental health outcomes and with a 1.74% (95% CI: 0.11, 3.40%) longer TL and 4.07% (95% CI: 2.01, 6.17%) higher mtDNAc. Psychological distress and suicidal ideation were associated with a lower mtDNAc of - 4.62% (95% CI: - 8.85, - 0.20%) and - 7.83% (95% CI: - 14.77, - 0.34%), respectively. No associations were found between mental health and TL. CONCLUSIONS: In this large-scale study, we showed the positive association between a healthy lifestyle and both biological ageing and different dimensions of mental health and well-being. We also indicated that living a healthy lifestyle contributes to more favourable biological&nbsp;ageing.</p

Using MRI to evaluate and predict therapeutic success from depot-based cancer vaccines

In the preclinical development of immunotherapy candidates, understanding the mechanism of action and determining biomarkers that accurately characterize the induced host immune responses is critical to improving their clinical interpretation. Magnetic resonance imaging (MRI) was used to evaluate in vivo changes in lymph node size in response to a peptide-based cancer vaccine therapy, formulated using DepoVax (DPX). DPX is a novel adjuvant lipid-in-oilâbased formulation that facilitates enhanced immune responses by retaining antigens at the injection site for extended latencies, promoting increased potentiation of immune cells. C57BL/6 mice were implanted with C3 (HPV) tumor cells and received either DPX or control treatments, 5 days post-implantation. Complete tumor eradication occurred in DPX-vaccinated animals and large volumetric increases were observed in the vaccine-draining right inguinal lymph node (VRILN) in DPX mice, likely corresponding to increased localized immune response to the vaccine. Upon evaluating the relative measure of vaccine-potentiated immune activation to tumor-induced immune response (VRILN/VLILN), receiver-operating characteristic (ROC) curves revealed an area under the curve (AUC) of 0.90 (±0.07), indicating high specificity and sensitivity as a predictive biomarker of vaccine efficacy. We have determined that for this tumor model, early MRI lymph node volumetric changes are predictive of depot immunotherapeutic success
