    Abstract Childhood, adolescent, and young adult (CAYA) cancer survivors may be at risk for a severe course of COVID-19. Little is known about the clinical course of COVID-19 in CAYA cancer survivors, or if additional preventive measures are warranted. We established a working group within the International Late Effects of Childhood Cancer Guideline Harmonization Group (IGHG) to summarize existing evidence and worldwide recommendations regarding evidence about factors/conditions associated with risk for a severe course of COVID-19 in CAYA cancer survivors, and to develop a consensus statement to provide guidance for healthcare practitioners and CAYA cancer survivors regarding COVID-19. + ID der Publikation: unilu_50168 + Sprache: Englisch + Bemerkungen: doi: 10.1002/pbc.28702 + Letzte Aktualisierung: 2020-11-04 18:28:47

    COVID-19 infection caused by SARS-CoV-2 pathogen has been a catastrophic pandemic outbreak all over the world, with exponential increasing of confirmed cases and, unfortunately, deaths. In this work we propose an AI-powered pipeline, based on the deep-learning paradigm, for automated COVID-19 detection and lesion categorization from CT scans. We first propose a new segmentation module aimed at automatically identifying lung parenchyma and lobes. Next, we combine the segmentation network with classification networks for COVID-19 identification and lesion categorization. We compare the model's classification results with those obtained by three expert radiologists on a dataset of 166 CT scans. Results showed a sensitivity of 90.3% and a specificity of 93.5% for COVID-19 detection, at least on par with those yielded by the expert radiologists, and an average lesion categorization accuracy of about 84%. Moreover, a significant role is played by prior lung and lobe segmentation, that allowed us to enhance classification performance by over 6 percent points. The interpretation of the trained AI models reveals that the most significant areas for supporting the decision on COVID-19 identification are consistent with the lesions clinically associated to the virus, i.e., crazy paving, consolidation and ground glass. This means that the artificial models are able to discriminate a positive patient from a negative one (both controls and patients with interstitial pneumonia tested negative to COVID) by evaluating the presence of those lesions into CT scans. Finally, the AI models are integrated into a user-friendly GUI to support AI explainability for radiologists, which is publicly available at http://perceivelab.com/covid-ai. The whole AI system is unique since, to the best of our knowledge, it is the first AI-based software, publicly available, that attempts to explain to radiologists what information is used by AI methods for making decisions and that proactively involves them in the decision loop to further improve the COVID-19 understanding.

    In this work, we release COVID-Twitter-BERT (CT-BERT), a transformer-based model, pretrained on a large corpus of Twitter messages on the topic of COVID-19. Our model shows a 10-30% marginal improvement compared to its base model, BERT-Large, on five different classification datasets. The largest improvements are on the target domain. Pretrained transformer models, such as CT-BERT, are trained on a specific target domain and can be used for a wide variety of natural language processing tasks, including classification, question-answering and chatbots. CT-BERT is optimised to be used on COVID-19 content, in particular social media posts from Twitter.

We aimed to study whether there is risk of incident depression, suicidal ideation or psychosis associated with HCQ as used for RA.MethodsWe performed a new-user cohort study using claims and electronic medical records from 10 sources and 3 countries (Germany, UK and USA). RA patients ≥18 years of age and initiating HCQ were compared with those initiating SSZ (active comparator) and followed up in the short (30 days) and long term (on treatment). Study outcomes included depression, suicide/suicidal ideation and hospitalization for psychosis. Propensity score stratification and calibration using negative control outcomes were used to address confounding. Cox models were fitted to estimate database-specific calibrated hazard ratios (HRs), with estimates pooled where I2 l40%.ResultsA total of 918 144 and 290 383 users of HCQ and SSZ, respectively, were included. No consistent risk of psychiatric events was observed with short-term HCQ (compared with SSZ) use, with meta-analytic HRs of 0.96 (95% CI 0.79, 1.16) for depression, 0.94 (95% CI 0.49, 1.77) for suicide/suicidal ideation and 1.03 (95% CI 0.66, 1.60) for psychosis. No consistent long-term risk was seen, with meta-analytic HRs of 0.94 (95% CI 0.71, 1.26) for depression, 0.77 (95% CI 0.56, 1.07) for suicide/suicidal ideation and 0.99 (95% CI 0.72, 1.35) for psychosis.ConclusionHCQ as used to treat RA does not appear to increase the risk of depression, suicide/suicidal ideation or psychosis compared with SSZ. No effects were seen in the short or long term. Use at a higher dose or for different indications needs further investigation.Trial registrationRegistered with EU PAS (reference no.

    Background Evidence about the impact of the pandemic of COVID-19 on the incidence rates of blood cultures contaminations and bloodstream infections in intensive care units (ICUs) remains scant. The objective of this study was to investigate the nationwide epidemiology of positive blood cultures drawn in ICUs during the first two pandemic waves of COVID-19 in Switzerland. Methods We analyzed data on positive blood cultures among ICU patients, prospectively collected through a nationwide surveillance system (ANRESIS), from March 30, 2020, to May 31, 2021, a 14-month timeframe that included a first wave of COVID-19, which affected the French and Italian-speaking regions, an interim period (summer 2020) and a second wave that affected the entire country. We used the number of ICU patient-days provided by the Swiss Federal Office of Public Health as denominator to calculate incidence rates of blood culture contaminations and bloodstream infections (ICU-BSI). Incidence rate ratios comparing the interim period with the second wave were determined by segmented Poisson regression models. Results A total of 1099 blood culture contaminations and 1616 ICU-BSIs were identified in 52 ICUs during the study. Overall, more episodes of blood culture contaminations and ICU-BSI were observed during the pandemic waves, compared to the interim period. The proportions of blood culture contaminations and ICU-BSI were positively associated with the ICU occupancy rate, which was higher during the COVID-19 waves. During the more representative second wave (versus interim period), we observed an increased incidence of blood culture contaminations (IRR 1.57, 95% CI 1.16–2.12) and ICU-BSI (IRR 1.20, 95% CI 1.03–1.39). Conclusions An increase in blood culture contaminations and ICU-BSIs was observed during the second COVID-19 pandemic wave, especially in months when the ICU burden of COVID-19 patients was high.

    Background: Children with and without disabilities consider playgrounds as significant places in their life, which offer opportunities for play and social interactions. Playgrounds are especially important in times when opportunities to meet are restricted, for example, due to the Covid-19 pandemic. Even though the primary purpose of playgrounds is to be a place for children to play, playground design is mainly determined by adults. Children`s voices regarding their use of playgrounds, and their wishes and needs to enhance participation on playgrounds are seldom addressed. In particularly perspectives of children with disabilities are often absent. The aim of this presentation is to give insight into how the perspectives of children with disabilities may contribute to playground design. Method: The presentation draws on an international project that explores children's perspectives through literature reviews and semi-structured interviews. Results: Children make important contributions to playground design. For example, children with disabilities show a unique understanding of their own situation and propose inclusive playground adjustments. Their unique perspectives on play could help playground providers to adapt playgrounds to their needs and wishes to ensure participation in play including opportunities for social interactions and challenges according to their abilities. Discussion: Children are the main user group of playgrounds. Child-focused participatory methods that include children with different abilities and a variety of needs and backgrounds should be included in processes of playground planning, evaluating, and monitoring to enhance playground design. This project has received funding from the European Union & Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 861257.

    Cough audio signal classification has been successfully used to diagnose a variety of respiratory conditions, and there has been significant interest in leveraging Machine Learning (ML) to provide widespread COVID-19 screening. However, there is currently no validated database of cough sounds with which to train such ML models. The COUGHVID dataset provides over 20,000 crowdsourced cough recordings representing a wide range of subject ages, genders, geographic locations, and COVID-19 statuses. First, we filtered the dataset using our open-sourced cough detection algorithm. Second, experienced pulmonologists labeled more than 2,000 recordings to diagnose medical abnormalities present in the coughs, thereby contributing one of the largest expert-labeled cough datasets in existence that can be used for a plethora of cough audio classification tasks. Finally, we ensured that coughs labeled as symptomatic and COVID-19 originate from countries with high infection rates, and that their expert labels are consistent. As a result, the COUGHVID dataset contributes a wealth of cough recordings for training ML models to address the world's most urgent health crises. 11 pages, 3 figures

    Der gesellschaftliche Wandel wirkt sich auf unsere Bildung und die sozialen Strukturen aus. Der Alltag von Kindern und Jugendlichen wird immer komplexer und fluider. Aktuell ist die Covid-19-Pandemie eine weitere Herausforderung und eine Belastung für deren Entwicklung. All’ das kann sich negativ auf die psychische Gesundheit auswirken, was unter anderem in der Schule sichtbar wird. Die Schulsozialarbeit bietet Schüler*innen Unterstützungsangebote, auch Einzelfallberatungen. Das professionelle Handeln richtet sich dabei stets nach den Bedürfnissen der Schüler*innen und hat zum Ziel, diese zu befähigen, die Herausforderungen und Belastungen zu meistern. Was sie dazu befähigt und Krisen meistern lässt, wurde in mehreren Langzeitstudien untersucht und wird unter dem «Konzept der Resilienz» zusammengefasst. Die Literatur zur Resilienzförderung zeigt auf, dass sich die sogenannten Resilienzfaktoren durch eine wertschätzende Beziehung fördern lassen. Dieser Arbeit nimmt die wichtigsten Erkenntnisse und Grundlagen der Resilienzforschung auf und prüft anhand der Arbeitsprinzipien für die Beratung, ob sich die Resilienz im Rahmen der Einzelfallberatung durch die Schulsozialarbeit fördern lässt. Anhand des ausgewählten Aspektes der Gewaltfreien Kommunikation wird in praktischen Beispielen aufgezeigt, wie sich die Resilienz, insbesondere durch eine wertschätzende Beziehung, aufbauen lässt. Ziel ist es, Gewaltfreie Kommunikation als Methode für die Förderung der Resilienz zugänglich zu machen. + Code Diss LU: hslusa basa be + Code Diss LU: hslusa basp be + Code Diss LU: hslusa bask be + Fussnote: Bachelor-Arbeit, Hochschule Luzern – Soziale Arbeit, Studienrichtung Soziokultur & Sozialarbeit & Sozialpädagogik, 2021 + NL-Code: NLLUHSA202110

    Objectives: Seroprevalence studies to assess the spread of SARS-CoV-2 infection in the general population and subgroups are key for evaluating mitigation and vaccination policies and for understanding the spread of the disease both on the national level and for comparison with the international community. Methods: Corona Immunitas is a research program of coordinated, population-based, seroprevalence studies implemented by Swiss School of Public Health (SSPH+). Over 28,340 participants, randomly selected and age-stratified, with some regional specificities will be included. Additional studies in vulnerable and highly exposed subpopulations are also planned. The studies will assess population immunological status during the pandemic. Results: Phase one (first wave of pandemic) estimates from Geneva showed a steady increase in seroprevalence up to 10.8% (95% CI 8.2-13.9, n = 775) by May 9, 2020. Since June, Zurich, Lausanne, Basel City/Land, Ticino, and Fribourg recruited a total of 5973 participants for phase two thus far. Conclusions: Corona Immunitas will generate reliable, comparable, and high-quality serological and epidemiological data with extensive coverage of Switzerland and of several subpopulations, informing health policies and decision making in both economic and societal sectors.
