We present CCD observations of 102 Landolt standard stars obtained with the Ritchey‐Chrétien spectrograph on the Cerro Tololo Inter‐American Observatory 1.5 m telescope. Using stellar atmosphere models, we have extended the flux points to our six spectrophotometric secondary standards, in both the blue and the red, allowing us to produce flux‐calibrated spectra that span a wavelength range from 3050 Å to 1.1 μm. Mean differences betweenUBVRIspectrophotometry computed using Bessell’s standard passbands and Landolt’s published photometry were determined to be 1% or less. Observers in both hemispheres will find these spectra useful for flux‐calibrating spectra, and through the use of accurately constructed instrumental passbands, will be able to compute accurate corrections to bring instrumental magnitudes to any desired standard photometric system (S‐corrections). In addition, by combining empirical and modeled spectra of the Sun, Sirius, and Vega, we calculate and compare synthetic photometry to observed photometry taken from the literature for these three stars.

Investments in strong research networks are essential to ensure that public health research provides adequate and robust evidence for informed policy-making. There is a need for close collaboration and mutual knowledge translation between researchers from various disciplines, as well as between research, practice and policy to effectively shape the health promotion and prevention landscape. In the German federal state of Baden-Württemberg (BW), the Competence Network Preventive Medicine BW (KNPM), established in 2021 and funded by the BW Ministry of Science, Research and Arts, unites the five medical faculties in BW. Within the KNPM and its seven working groups (WG), we have invested heavily in building relationships with ministries, the public health service, health insurance companies, and other local actors. We have learned that such cross-linked networks are crucial for evaluating interventions and generating actionable evidence for implementing effective preventive measures. The collection and use of data from a variety of areas and sources is important here. In our work, we emphasise that we can only achieve sustainable public health by applying innovative scientific methods, but also through evidence that is understandable, applicable, and relevant to a range of actors in practice and policy. Objectives In line with the EPH conference theme Investing for sustainable health and well-being, this session has the aim to explore the role of cross-linked research networks in generating evidence, translating it into practice and thus transforming health promotion and prevention. It targets an interdisciplinary audience from academia, policy and practice. The following topics will be explored: • Transforming landscapes: Potentials of research networks to shape health promotion and prevention. • Navigating Complexity: Strategies to address the challenges of cross-linked research networks. • Co-Producing Knowledge: Fostering interdisciplinary collaboration and co-production of evidence to enhance research impact across different contexts. • Evidence for action: Mechanisms for effective evidence translation and targeted dissemination to a range of audiences. Format This session will provide an overview of the KNPM research network. Four of its WGs will contribute brief thematic presentations in Pecha Kucha-style, offering insights into their current scientific work. The presentations will be followed by an interactive discussion inviting the audience to share their perspectives, experiences and reflections on the topics. Key messages • Investment in research networks contributes to evidence-based health promotion and prevention landscapes by strengthening infrastructures, pooling resources and diverse expertise. • Challenges of translating evidence between public health research, policy and practice can be addressed by taking into account the different needs and perspectives within a cross-linked network.

Purpose - The aim of this paper is to demonstrate that, with a bit of creative thinking, elements of certain university-wide projects (in this case study, establishing an iTunes U site) can be incorporated into student studies and assessment as real-world learning opportunities. Design/methodology/approach - Describes three different approaches adopted by Swinburne University of Technology to provide real-world learning opportunities for its students through its project to establish an iTunes U presence. Highlights the problems encountered with these approaches and what Swinburne would do differently to overcome these issues. Findings - iTunes U provides a real opportunity for showcasing student work and talent beyond the university. The key to success lies in embedding what you want the students to do deeply within assessment processes to ensure the work provides a relevant and valid learning experience. Part of this is establishing a realistic client-service-provider relationship with the students. Research limitations/implications - This paper is based on the observations and anecdotal feedback given to the content coordinator for iTunes U at Swinburne. Future research should seek ethics clearance so that students and staff can be interviewed about their experiences in more depth. Practical implications - This paper offers advice to other institutions looking to engage students in broader university projects, through integration with coursework. Originality/value - Hundreds of universities have iTunes U sites, or are exploring the use of iTunes U and/or YouTube. Ideas for how to successfully involve students in these broader university initiatives will be of interest to all these institutes. [PUBLICATION ABSTRACT]

This round table is co-organized by EUPHA-HL, EUPHA-CAPH, EUPHA-PHMR, and the WHO Collaborating Centre for Health Literacy. The event will share unique insights into novel evidence from international studies and young people's information ecosystems, how health mis- and disinformation are detrimental, and what public health and societies can do about it. Young people are growing up in digital environments where social media and online platforms are primary sources of health information, but also major channels for the rapid spread of disinformation. Evidence shows that 58% of young adults regret a health decision made based on misinformation, despite 72% expressing confidence in their ability to distinguish truth from falsehoods. While young people in Europe are ill-equipped with health literacy, this gap highlights the complex interplay between empowerment and vulnerability, as adolescents are both creators and consumers in participatory online spaces where peer influence and emotional content can override accuracy. Exposure to false health information is linked to poorer health choices, increased anxiety, and the erosion of trust in health institutions - a menacing phenomenon going on globally. Schools and education systems are vital in addressing these challenges. Integrating health literacy and critical thinking into curricula empowers students to navigate complex information environments and resist misinformation. However, many teachers lack the training and resources needed to effectively address these issues, and disparities in access to quality media literacy education persist. To promote health literacy, public health practitioners, educators, and teachers must receive targeted training in media and health literacy, as well as ongoing support to model trustworthiness and foster open dialogue. As young people face increasing pressures and uncertainties in a rapidly evolving information landscape, urgent action is needed to strengthen support systems, improve access to trustworthy health information, and build the capacity of schools and educators to empower the next generation to navigate digital health ecosystems safely and confidently. After a short introduction by the chairs, the panel members will share a short 2-to-3-minute statement from their point of view on the matter of information ecosystems and health disinformation. Following, the chairs will prepare individual questions for each panellist and engage them in a discussion, which shortly after will open towards the audience for them to participate actively with the panellists in a 30-minute discussion, also using the online Slido platform. Key messages • Gain exclusive insights into how health misinformation impacts young people and learn proven strategies to boost digital health literacy and resilience. • Connect with experts and peers to discover actionable solutions for empowering youth to navigate online health information safely and confidently.

Abstract Background There is limited evidence on point-of-care ultrasound for tuberculosis (TB), but studies suggest high sensitivity, especially for lung ultrasound (LUS). However, insufficient data are available on specificity of the examination and its generalizability to a broader patient population. Aims Our study aimed to establish accuracy for lung, chest, and abdominal ultrasound, individually and in combination, for TB diagnosis. Methods We conducted a prospective diagnostic accuracy study among consecutive adult out- and inpatients with probable TB in three German referral hospitals. We applied a comprehensive standardized ultrasound protocol. TB diagnosis was established by a microbiological reference standard including polymerase chain reaction and culture. Results A total of 102 participants originating from 30 different countries were enrolled. HIV prevalence was 7/99 (7%) and 73/102 (72%) had confirmed TB. TB was limited to the lungs in 15/34 (44%) of refugees and 27/39 (69%) in nonrefugees. Focused assessment with sonography for HIV-associated tuberculosis had a sensitivity of 40% (95% confidence interval [CI], 30–52) and specificity of 55% (95% CI, 38–72). Additional findings, such as small subpleural consolidations on LUS had a high sensitivity (88%; 95% CI, 78–93), but a low specificity (17%; 95% CI, 8–35). Larger consolidations in the lung apices had a sensitivity of 19% (95% CI, 12–30) and a specificity of 97% (95% CI, 83–100). Conclusions Our study establishes the first data on LUS performance against a comprehensive reference standard. Overall, our data suggest that ultrasound does not meet the requirements for triage but previously described and novel ultrasound targets in combination could aid in the clinical decision making. Registry: DRKS00026636 This German multicenter study prospectively investigated lung and abdominal point-of-care ultrasound in patients with presumed tuberculosis and revealed limited accuracy. Point-of-care ultrasound has limited value as a standalone test but could be part of an algorithmic approach for diagnosis. Lay Summary Tuberculosis (TB) is a serious lung disease. Using ultrasound to diagnose TB shows promise, especially for the lungs, but more information is needed about its accuracy. To use of lung ultrasound for triage, it would need to correctly identify at least 90% of persons with TB and not be falsely positive in more than 30% of persons without TB. Our study aimed to determine how well lung, chest, and abdominal ultrasounds could predict TB. We examined adults who might have TB at three hospitals in Germany, using a thorough ultrasound method and confirmed TB diagnoses with culture or polymerase chain reaction. We studied 102 participants from 30 countries, with 7% having HIV. TB was confirmed in 72% of the participants. The focused assessment with sonography for HIV-associated tuberculosis method for HIV-associated TB had a 40% chance of correctly identifying TB and a 55% chance of correctly identifying those without TB. Small lung abnormalities seen on ultrasound had high sensitivity (88%) but low specificity (17%). Larger abnormalities in the top part of the lungs had low sensitivity (19%) but high specificity (97%). In conclusion, lung ultrasound alone does not meet the set expectations for a test to diagnose TB or triage patients for further testing. Nonetheless, combining different ultrasound findings could help doctors make better decisions about TB diagnosis.

The passbands of the MACHO blue and red photometric bands have been synthesized and tested by comparing the synthetic photometry of the Vilnius spectra with the actual photometry of the Landolt field Ru 149 taken with the MACHO telescope. Transformations betweenB maandR maand standard CousinsVandRwere derived. The effect of interstellar reddening on theV−RandB ma−R macolors of F stars has been calculated. A new calibration ofV−R,T eff, andBC V for metal‐poor A–K stars is presented.

Herzog & de Meuron of Basel bailed out of a commission from the University of Texas because of difficulties with the Board of Regents, who blindsided the architects with a style debate. The school lost a chance to have a great art museum and a great architecture dean.
