The Civil Court as Risk Regulator: The Issue of its Legitimacy
Taking the Urgenda case on climate change liability as an example, this article researches the more general question into the legitimacy of risk regulation by civil courts. Which principles determine the legitimacy of a civil court’s participation, especially in the domain of societal risk regulation? The central claim is that these principles concern (amongst many other things) the position of the court, the tools of the court, and the attitude of the court. In other words, they have their source in constitutional law, civil (procedural) law, and professional ethics respectively. This claim is substantiated by an analysis of these principles, their interpretation, and the way they contribute to a normative/theoretical framework for the assessment of the legitimacy of judicial rulings.
Decorated bodies for eternal life: A multidisciplinary study of late Roman Period stucco-shrouded portrait mummies from Saqqara (Egypt)
This study focuses on the multidisciplinary investigation of three stucco-shrouded mummies with mummy portrait from Egypt dating from the late 3rd to the middle of the 4th century AD, corresponding to the late Roman Period. These three mummies were excavated in the early 17th and late 19th centuries in the Saqqara necropolis near the ancient Egyptian capital of Memphis. Two of them experienced an interesting collection history, when they became part of the collection of the Elector of Saxony and King of Poland August II in Dresden, Germany, in 1728. The investigation includes information about the mummies' discovery, collection history and shroud decoration obtained through Egyptological expertise. In addition, information on the state of preservation, technique of artificial mummification, age at death, sex, body height and health of the deceased was achieved through computed tomography (CT) analysis. Research yielded an adult male, a middle-aged female and a young female. Due to the rather poorly preserved bodies of the male and middle-aged female, a specific technique of artificial mummification could not be ascertained. Brain and several internal organs of the well-preserved young female were identified. Wooden boards, beads of necklaces, a hairpin, and metal dense items, such as lead seals, nails and two coins or medallions were discovered. Paleopathological findings included carious lesions, Schmorl's nodes, evidence of arthritis and a vertebral hemangioma. The study revealed insights on the decoration and burial preparation of individuals of upper socioeconomic status living in the late Roman Period, as well as comprehensive bioanthropological information of the deceased.
The evolution of long bone microstructure and lifestyle in lissamphibians
The compactness profile of femoral cross-sections and body size of 105 specimens of 46 species of lissamphibians was studied to assess the effect of lifestyle (aquatic, amphibious, or terrestrial). Several tests that incorporate phylogenetic information (permutational multiple linear regression incorporating phylogenetic distances, logistic regression using phylogenetic weighting, concentrated-changes tests) show that the return to a fully aquatic lifestyle is associated with an increase in the compactness of the femur and an increase in body size. However, amphibious taxa cannot be distinguished from terrestrial ones solely on the basis of size or compactness. Body size and compactness profile parameters of the femur exhibit a phylogenetic signal (i.e., closely related taxa tend to be more similar to each other than to distantly related taxa). Mathematical equations obtained from our data by using logistic regression with phylogenetic weighting are used to infer the lifestyle of four early stegocephalians. The results are generally congruent with prevailing paleontological interpretations, which suggests that this method could be applied to infer the lifestyle of early taxa whose lifestyle is poorly understood.
The intergenerational transmission of family meal practices: a mixed-methods study of parents of young children
The current mixed-methods study explored qualitative accounts of prior childhood experiences and current contextual factors around family meals across three quantitatively informed categories of family meal frequency patterns from adolescence to parenthood: (i) 'maintainers' of family meals across generations; (ii) 'starters' of family meals in the next generation; and (iii) 'inconsistent' family meal patterns across generations. Quantitative survey data collected as part of the first (1998-1999) and fourth (2015-2016) waves of the longitudinal Project EAT (Eating and Activity in Adolescents and Young Adults) study and qualitative interviews conducted with a subset (n 40) of Project EAT parent participants in 2016-2017. Surveys were completed in school (Wave 1) and online (Wave 4); qualitative interviews were completed in-person or over the telephone.ParticipantsParents of children of pre-school age (n 40) who had also completed Project EAT surveys at Wave 1 and Wave 4. Findings revealed salient variation within each overarching theme around family meal influences ('early childhood experiences', 'influence of partner', 'household skills' and 'family priorities') across the three intergenerational family meal patterns, in which 'maintainers' had numerous influences that supported the practice of family meals; 'starters' experienced some supports and some challenges; and 'inconsistents' experienced many barriers to making family meals a regular practice. Family meal interventions should address differences in cooking and planning skills, aim to reach all adults in the home, and seek to help parents who did not eat family meals as a child develop an understanding of how and why they might start this tradition with their family.
First, Do No Harm: Understanding Primary Care Providers’ Perception of Risks Associated With Discussing Weight With Pediatric Patients
Many health care providers struggle with if- and how-to discuss weight with their pediatric patients. This study used one-on-one interviews with primary care providers (n = 20) to better understand their: (1) perception of risks associated with talking about weight with pediatric patients, (2) commitment to adhering to best practices of pediatric weight management, and (3) approaches to mitigate perceived risks. Providers felt concerned that discussing weight with children during clinic visits may have unintended negative impacts. Despite perceived risks, providers continued regular BMI screening and weight-focused conversations, but took care with regard to language and approach with the goal of mitigating perceived risks. Findings suggest that pediatric primary care providers perceive that engaging in weight-related discussions with their patients has the potential to lead to negative, unintended consequences. Future research is needed to understand if weight-focused conversations should be avoided altogether or if there are approaches that can effectively mitigate risks.
Change that Matters: A Health Behavior Change and Behavioral Health Curriculum for Primary Care
Although primary care is an ideal setting in which to address behavioral influences on health, clinicians spend little time discussing preventive care, including lifestyle counseling. There is a dearth of comprehensive training and evidence-based resources to educate clinicians in how to effectively engage with patients about these topics. This study describes and evaluates the acceptability of Change that Matters: Promoting Healthy Behaviors, a ten-module curriculum to train clinicians in brief, evidence-based interventions. Each module includes three parts: interactive patient handouts, didactic training, and electronic health record templates to guide the discussion and after visit summary. A two-part, mixed-methods pilot study was used to evaluate the acceptability of the curriculum in a family medicine residency clinic. In Study 1, external family medicine faculty experts ( N  = 11) provided written feedback on the patient handouts. In Study 2, 20 residents and 20 patients completed qualitative interviews regarding their experience with curricular materials. Content analysis was used to extract qualitative themes. Experts rated the patient handouts as highly understandable and actionable. Resident themes indicated that the curriculum provided concrete tools to address health behavior change, helped structure patient discussions, and increased confidence. Patients felt empowered to make behavior changes. This new curriculum addresses a gap in existing resources, and is available for free download online which can facilitate dissemination ( https://changethatmatters.umn.edu/ ). Research has found the curriculum to be acceptable to experts, residents, and patients. Future studies need to explore its impact on the behavior of both clinicians and patients.
MRI findings differentiating tonsillar herniation caused by idiopathic intracranial hypertension from Chiari I malformation
Purpose Some patients with idiopathic intracranial hypertension (IIH) have cerebellar tonsillar herniation ≥ 5 mm mimicking Chiari malformation I (CMI), which can result in misdiagnosis and unjustified treatment. Our purpose was to identify IIH patients with tonsillar herniation ≥ 5 mm (IIH TH ) and compare with CMI patients to assess imaging findings that could distinguish the two conditions. Methods Ninety-eight patients with IIH, 81 patients with CMI, and 99 controls were retrospectively assessed. Two neuroradiologists blindly reviewed MR images. IIH TH patients were compared with CMI patients and controls regarding the extent of tonsillar herniation (ETH), bilateral transverse sinus stenosis (BTSS), hypophysis-sella ratio (HSR), and bilateral tortuosity of optic nerve (BTON). Results 13/98 (13.2%) IIH patients had tonsillar herniation ≥ 5 mm (IIH TH ) and were significantly younger and had higher BMI compared with CMI patients and controls. ETH was significantly less in the IIH TH than CMI (6.5 ± 2.4 mm vs. 10.9 ± 4.4 mm; p  < 0.001). BTSS and HSR < 0.5 were more common in IIH TH than CMI ( p  < 0.001 and p  = 0.003, respectively). No differences were seen between CMI and controls. BTON was significantly more common in IIH TH compared to control ( p  = 0.01) but not to the CMI ( p  = 0.36). Sensitivity and specificity to differentiate IIH TH from CMI were 69.2% and 96.1% for BTSS and 69.2% and 75.3% for HSR < 0.5. Conclusion The presence of BTSS and/or HSR < 0.5 in patients with ETH ≥ 5 mm should suggest further evaluation to exclude IIH before considering CMI surgery.
Blessing or curse? A survey on the Impact of Generative AI on Fake News
Fake news significantly influence our society. They impact consumers, voters, and many other societal groups. While Fake News exist for a centuries, Generative AI brings fake news on a new level. It is now possible to automate the creation of masses of high-quality individually targeted Fake News. On the other end, Generative AI can also help detecting Fake News. Both fields are young but developing fast. This survey provides a comprehensive examination of the research and practical use of Generative AI for Fake News detection and creation in 2024. Following the Structured Literature Survey approach, the paper synthesizes current results in the following topic clusters 1) enabling technologies, 2) creation of Fake News, 3) case study social media as most relevant distribution channel, 4) detection of Fake News, and 5) deepfakes as upcoming technology. The article also identifies current challenges and open issues.
Reproducible functional connectivity alterations are associated with autism spectrum disorder
Despite the high clinical burden little is known about pathophysiology underlying autism spectrum disorder (ASD). Recent resting state functional magnetic resonance imaging (rs-fMRI) studies have found atypical synchronization of brain activity in ASD. However, no consensus has been reached on the nature and clinical relevance of these alterations. Here we address these questions in the most comprehensive, large-scale effort to date comprising evaluation of four large ASD cohorts. We followed a strict exploration and replication procedure to identify core rs-fMRI functional connectivity (degree centrality) alterations associated with ASD as compared to typically developing (TD) controls (ASD: N=841, TD: N=984). We then tested for associations of these imaging phenotypes with clinical and demographic factors such as age, sex, medication status and clinical symptom severity. We find reproducible patterns of ASD-associated functional hyper- and hypo-connectivity with hypo-connectivity being primarily restricted to sensory-motor regions and hyper-connectivity hubs being predominately located in prefrontal and parietal cortices. We establish shifts in between-network connectivity from outside to within the identified regions as a key driver of these abnormalities. The magnitude of these alterations is linked to core ASD symptoms related to communication and social interaction and is not affected by age, sex or medication status. The identified brain functional alterations provide a reproducible pathophysiological phenotype underlying the diagnosis of ASD reconciling previous divergent findings. The large effect sizes in standardized cohorts and the link to clinical symptoms emphasize the importance of the identified imaging alterations as potential treatment and stratification biomarkers for ASD.
