Abstract	The main aim of this study was to validate 500 true-false general-knowledge questions in Russian. These norms are valuable to researchers in many fields, as is shown by the impact and relevance of similar norms available in other languages. Although the Russian language is widely spoken, there are no norms available in this language for this type of questions. True-false questions are very useful for measuring semantic memory, among other topics, in neurocognitive studies where there is a trade-off between experimental time and the need for many trials. These types of experimental materials are heavily rooted in cultural background knowledge, making the mere translation from one language to another insufficient. The present research aims to fill this gap. One hundred fifty-five participants answered 500 true-false general knowledge questions split over several consecutive days and three topics: Social Sciences, Natural Sciences, and Culture & Sport. The participants' task was to indicate whether the statements were true or not, as well as the confidence they had in the correctness of their answer. Despite obtaining questions on each of the topics covering all difficulty levels, grouped analyses showed that Social Science's accuracy was higher than for Natural Science's or Culture & Sport questions. In relation to confidence, the grouped perceived difficulty was higher for questions about Culture & Sports when compared with the other two topics. Thus, this study reports and makes available a large pool of Russian true-false general knowledge questions covering different levels of difficulty.

Title translation	Bad news communication protocols in health. Limitations, challenges and proposals.
Abstract	Bad news communication is a frequent and difficult task for health care professionals. There are valuable protocols that systematize this task through a series of steps. However, these protocols have important limitations. The objective of this work is to analyze the main shortcomings of the protocols for CMN, according to the available ethical and clinical evidence. An orientation by objectives is recommended, considering that communication of bad news is a contextual process that involves different actors, and that requires reflection and flexibility to determine the best course of action according to the circumstances of each particular case. The importance of affectionate attention for patients and their relatives is highlighted.

Abstract	Purpose: Bile duct injury is a significant problem in laparoscopic cholecystectomy and can have grave consequences for patient outcomes. Automatic identification of the critical structures (cystic duct and cystic artery) could potentially reduce complications during surgery by helping the surgeon establish Critical View of Safety, or eventually may even provide real time intra-operative guidance. Methods: A computer vision model was trained to identify the critical structures. Label relaxation enabled the model to cope with ambiguous spatial extent and high annotation variability. Pseudo-label self-supervision allowed the model to use unlabelled data, which can be particularly beneficial when scarce labelled data is available for training. Intrinsic variability in annotations was assessed across several annotators, quantifying the extent of annotation ambiguity and setting a baseline for model accuracy. Results: Using 3050 labelled and 3682 unlabelled cholecystectomy frames, the model achieved an IoU of 65% and presence detection F1 score of 75%. Inter-annotator IoU agreement was 70%, demonstrating the model was near human-level agreement on average in this dataset. The model's outputs were validated by three expert surgeons, who confirmed that its outputs were accurate and promising for future usage. Conclusion: Identification of critical structures can achieve high accuracy, and is a promising step towards computer-assisted intervention in addition to potential applications in analytics and education. High accuracy and surgeon approval is maintained when detecting the structures separately as distinct classes. Future work will focus on guaranteeing safe identification of critical anatomy, including the bile duct, and validating the performance of automated approaches.

Abstract	The aim of this study was to describe the initial oral microbiota and how delivery mode and feeding practices impact its diversity in 0-2-month-old infants. This was a cross-sectional study that consisted of one collection of saliva samples from 0-2-month infants at baseline. Ten pairs of mothers and infants were selected. Medical health history, pregnancy, birth, feeding practices (breastfeeding or milk formula), and infant health status was obtained. Pooled microbial samples were obtained from the oral surfaces using a sterile cotton swab. Infants did not receive any breast milk before sampling. After collection, each swab was analyzed through microbiological culture-based procedures, using selective mediums. Cultures were analyzed for the presence of Streptococci, Lactobacillus, Staphylococcus, Enterobacterium , and Candida albicans . Twenty percent of the samples were serially diluted (10-2) to assess the number of bacteria expressed as CFU. Bacillota was the leading phylogenetic group in the infant's pooled microbial sample. The most prevalent genera were Streptococcus, Lactobacillus , and Staphylococcus . Two participants had a positive growth of Candida albicans . The association between genus group, type of delivery, and feeding practices was not statistically significant (p > 0.05). Lactobacillus genus was frequently present in the cesarean delivery group but with slightly higher counts in a vaginal delivery study subject. Exclusively breastfed infants showed presence of Streptococcus, Lactobacillus, Staphylococcus . The oral microbiome in infants (0-2 month-old) is highly heterogeneous and dynamic. Microbiota composition seems to be impacted by mode of delivery, with slight differences among groups. Breastmilk appears as an essential factor in maintaining the oral microbiome's stability and diversity.

Abstract	Background: The glenoid track concept is now widely accepted, and its evaluation is considered essential for making decisions about surgery. Purpose: To define preoperative descriptive data and clinical and functional features in patients with anterior glenohumeral instability according to glenoid track status and to analyze the influence of off-track Hill-Sachs (HS) lesions on preoperative shoulder function. Study design: Case-control study; Level of evidence, 3. Methods: Preoperative magnetic resonance imaging or computed tomography scans were used to measure the glenoid track. Descriptive data and preoperative objective and subjective clinical and functional features were compared between patients with on-track HS lesions versus off-track HS lesions. Multivariate regression analysis was conducted to identify potential risk factors for off-track HS lesion development. Results: A total of 235 patients (201 men, 34 women; mean age, 29.6 ± 8.6 years) were included- 134 shoulders (57%) with on-track HS lesions and 101 shoulders (43%) with off-track HS lesions. Age <20 years at first dislocation, number of dislocations, and ≥2 years between first dislocation and surgery were significantly different between the study groups ( Conclusion: Characteristics related to a history of instability (age <20 years at first instability episode, larger number of dislocations, ≥2 years between first dislocation and surgery) were found to be risk factors for the development of an off-track HS lesion in this study. Off-track lesions led to a higher degree of instability and worse objective and subjective preoperative shoulder function versus on-track HS lesions.

Abstract	Since the World Health Organization (WHO, February 2, 2020) reported that the spread of coronavirus disease has been accompanied by a "massive infodemic," the COVID-19 outbreak has become a national and international battleground of a struggle against misinformation. Fact-checking outlets around the world have been actively counteracting false and misleading information surrounding the pandemic. In this article, we conceptualize fact checkers in terms of the "interpretative power" that journalism holds in processes of political performances (Alexander in Soc Theory 22(4): 527-573, 2004, in: The performance of politics. Obama's victory and the struggle for democratic power. Oxford University Press, Oxford/New York, 2010). Drawing on virus-related fact checks from Poynter's International Fact-Checking Network (IFCN) database, we make two arguments. First, we argue that the new phenomenon of specialized "fact checking" might be considered as a further explicitly differentiated element of Alexander's model of cultural performance, which fulfills a double duty: trying to contribute to further "de-fusion" (separating audiences from actors when the latter lack authenticity and credibility) on the one hand, and working to overcome it on the other. Second, we explain how new fact-checking practices have become a reflexive supplement to the news media of the civil sphere that might be able to help the civil sphere's communicative institutions to defend truthfulness in a manner that contributes to democracy.

Abstract	Purpose: Surgical workflow estimation techniques aim to divide a surgical video into temporal segments based on predefined surgical actions or objectives, which can be of different granularity such as steps or phases. Potential applications range from real-time intra-operative feedback to automatic post-operative reports and analysis. A common approach in the literature for performing automatic surgical phase estimation is to decouple the problem into two stages: feature extraction from a single frame and temporal feature fusion. This approach is performed in two stages due to computational restrictions when processing large spatio-temporal sequences. Methods: The majority of existing works focus on pushing the performance solely through temporal model development. Differently, we follow a data-centric approach and propose a training pipeline that enables models to maximise the usage of existing datasets, which are generally used in isolation. Specifically, we use dense phase annotations available in Cholec80, and sparse scene (i.e., instrument and anatomy) segmentation annotation available in CholecSeg8k in less than 5% of the overlapping frames. We propose a simple multi-task encoder that effectively fuses both streams, when available, based on their importance and jointly optimise them for performing accurate phase prediction. Results and conclusion: We show that with a small fraction of scene segmentation annotations, a relatively simple model can obtain comparable results than previous state-of-the-art and more complex architectures when evaluated in similar settings. We hope that this data-centric approach can encourage new research directions where data, and how to use it, plays an important role along with model development.

Abstract	The misalignment between workers’ educational levels and the educational level typically required for their occupations, namely educational mismatch, has become widespread. However, despite its potential costs, there is little evidence of this situation in developing countries. Using longitudinal and retrospective data of employment histories between 2009 and 2019, this paper conducts sequence analysis to construct a typology of educational mismatch trajectories among Chilean workers. We demonstrate that mismatch is a prevalent and persistent phenomenon. Once people enter the labor market, either as undereducated or overeducated workers, they tend to stay in such positions for extended periods of time. Moreover, we find significant wage penalties for workers in a mismatch situation. Results indicate that females and young, less-educated men are more prone to follow trajectories with longer periods of mismatch or unemployment. New avenues for research and the need for public policies looking at these phenomena are required to avoid people’s dissatisfaction due to a possible false promise that more education can improve their life standards.

Abstract	Head and neck cancer (HNC) is a prevalent and aggressive form of cancer with high mortality rates and significant implications for nutritional status. Accurate assessment of malnutrition in patients with HNC is crucial for optimizing treatment outcomes and improving survival rates. This study aimed to evaluate the use of ultrasound techniques for predicting nutritional status, malnutrition, and cancer outcomes in patients with HNC. A total of 494 patients with HNC were included in this cross-sectional observational study. Various tools and body composition measurements, including muscle mass and adipose tissue ultrasound evaluations, were implemented. Using regression models, we mainly found that high levels of RF-CSA (rectus femoris cross-sectional area) were associated with a decreased risk of malnutrition (as defined with GLIM criteria (OR = 0.81, 95% CI: 0.68-0.98); as defined with PG-SGA (OR = 0.78, 95% CI: 0.62-0.98)) and sarcopenia (OR = 0.64, 95% CI: 0.49-0.82) after being adjusted for age, sex, and BMI. To predict the importance of muscle mass ultrasound variables on the risk of mortality, a nomogram, a random forest, and decision tree models were conducted. RF-CSA was the most important variable under the random forest model. The obtained C-index for the nomogram was 0.704, and the Brier score was 16.8. With an RF-CSA < 2.7 (AUC of 0.653 (0.59-0.77)) as a split, the decision tree model classified up to 68% of patients as possessing a high probability of survival. According to the cut-off value of 2.7 cm
