Published: February 2023

AbstractBackgroundRobot-assisted distal pancreatectomy (RDP) has been suggested to hold some benefits over laparoscopic distal pancreatectomy (LDP) but consensus and data on specific subgroups are lacking. This systematic review and meta-analysis reports the surgical and oncological outcome and costs between RDP and LDP including subgroups with intended spleen preservation and pancreatic ductal adenocarcinoma (PDAC).MethodsStudies comparing RDP and LDP were included from PubMed, Cochrane Central Register, and Embase (inception-July 2022). Primary outcomes were conversion and unplanned splenectomy. Secondary outcomes were R0 resection, lymph node yield, major morbidity, operative time, intraoperative blood loss, in-hospital mortality, operative costs, total costs and hospital stay.ResultsOverall, 43 studies with 6757 patients were included, 2514 after RDP and 4243 after LDP. RDP was associated with a longer operative time (MD = 18.21, 95% CI 2.18–34.24), less blood loss (MD = 54.50, 95% CI ﻿− 84.49–24.50), and a lower conversion rate (OR = 0.44, 95% CI﻿ 0.36–0.55) compared to LDP. In spleen-preserving procedures, RDP was associated with more Kimura procedures (OR = 2.23, 95% CI﻿ 1.37–3.64) and a lower rate of unplanned splenectomies (OR = 0.32, 95% CI﻿ 0.24–0.42). In patients with PDAC, RDP was associated with a higher lymph node yield (MD = 3.95, 95% CI ﻿1.67–6.23), but showed no difference in the rate of R0 resection (OR = 0.96, 95% CI﻿ 0.67–1.37). RDP was associated with higher total (MD = 3009.31, 95% CI ﻿1776.37–4242.24) and operative costs (MD = 3390.40, 95% CI ﻿1981.79–4799.00).ConclusionsRDP was associated with a lower conversion rate, a higher spleen preservation rate and, in patients with PDAC, a higher lymph node yield and similar R0 resection rate, as compared to LDP. The potential benefits of RDP need to be weighed against the higher total and operative costs in future randomized trials.

AbstractBackgroundIn recent years, the use of Indocyanine Green (ICG) fluorescence-guided surgery during open and laparoscopic procedures has exponentially expanded across various clinical settings. The European Association of Endoscopic Surgery (EAES) initiated a consensus development conference on this topic with the aim of creating evidence-based statements and recommendations for the surgical community.MethodsAn expert panel of surgeons has been selected and invited to participate to this project. Systematic reviews of the PubMed, Embase and Cochrane libraries were performed to identify evidence on potential benefits of ICG fluorescence-guided surgery on clinical practice and patient outcomes. Statements and recommendations were prepared and unanimously agreed by the panel; they were then submitted to all EAES members through a two-rounds online survey and results presented at the EAES annual congress, Barcelona, November 2021.ResultsA total of 18,273 abstracts were screened with 117 articles included. 22 statements and 16 recommendations were generated and approved. In some areas, such as the use of ICG fluorescence-guided surgery during laparoscopic cholecystectomy, the perfusion assessment in colorectal surgery and the search for the sentinel lymph nodes in gynaecological malignancies, the large number of evidences in literature has allowed us to strongly recommend the use of ICG for a better anatomical definition and a reduction in post-operative complications.ConclusionsOverall, from the systematic literature review performed by the experts panel and the survey extended to all EAES members, ICG fluorescence-guided surgery could be considered a safe and effective technology. Future robust clinical research is required to specifically validate multiple organ-specific applications and the potential benefits of this technique on clinical outcomes.

Abstract
Background
Diabetes mellitus type 2 is a common disease that poses a challenge to the healthcare system. The disease is very often diagnosed late. A better understanding of the relationship between the gut microbiome and type 2 diabetes can support early detection and form an approach for therapies. Microbiome analysis offers a potential opportunity to find markers for this disease. Next-generation sequencing methods can be used to identify the bacteria present in the stool sample and to generate a microbiome profile through an analysis pipeline. Statistical analysis, e.g., using Student’s t-test, allows the identification of significant differences. The investigations are not only focused on single bacteria, but on the determination of a comprehensive profile. Also, the consideration of the functional microbiome is included in the analyses. The dataset is not from a clinical survey, but very extensive.

Results
By examining 946 microbiome profiles of diabetes mellitus type 2 sufferers (272) and healthy control persons (674), a large number of significant genera (25) are revealed. It is possible to identify a large profile for type 2 diabetes disease. Furthermore, it is shown that the diversity of bacteria per taxonomic level in the group of persons with diabetes mellitus type 2 is significantly reduced compared to a healthy control group. In addition, six pathways are determined to be significant for type 2 diabetes describing the fermentation to butyrate. These parameters tend to have high potential for disease detection.

Conclusions
With this investigation of the gut microbiome of persons with diabetes type 2 disease, we present significant bacteria and pathways characteristic of this disease.
High Costs and Low Benefits: Analysis and Evaluation of the “I’m Not Stupid” Argument
Authors: Jansen Henrike 
Published: February 2023

AbstractThis article presents an analysis and evaluation of what I call the “I’m not stupid” argument. This argument has ancient roots, which lie in Aristotle’s famous description of the weak man’s and strong man’s arguments. An “I’m not stupid” argument is typically used in a context of accusation and defense, by a defendant who argues that they did not commit the act of which they have been accused. The analysis of this type of argument takes the shape of an argumentative pattern, which displays a full-fledged representation of its argumentation structure. It is based on a collection of ten contemporary instances of the “I’m not stupid” argument. Although ten instances constitute a small collection, the wide variation in the argumentative elements that they express explicitly or leave implicit made it possible to identify five new key premises in comparison with previous analyses of the weak man’s and strong man’s arguments (Walton, Tindale and Gordon 2014 in Argumentation 28:85–119, 2014; Walton 2019 in Argumentation 33:45–74, 2019). These new premises show that the crucial point of an evaluation of this argument is the arguer's supposedly rational character in making a gain-loss calculation. They also show that we need empirical data to strengthen our analyses of argument schemes and argumentation structures.
The Pragma-Dialectical Approach to the Fallacies Revisited
Authors: van Eemeren Frans H. , Garssen Bart 
Published: February 2023

AbstractThis article explains the design and development of the pragma-dialectical approach to fallacies. In this approach fallacies are viewed as violations of the standards for critical discussion that are expressed in a code of conduct for reasonable argumentative discourse. After the problem-solving validity in resolving differences of opinion of the rules of this code has been discussed, their conventional validity for real-life arguers is demonstrated. Starting from the extended version of the theory in which the strategic maneuvering taking place in argumentative discourse is included, the article explains that the violations of the rules that are committed in the fallacies involve derailments of strategic maneuvering. This culminates in a discussion of the exploitation of hidden fallaciousness as an unreasonable way of increasing the effectiveness of argumentative discourse – a vital topic of research in present-day pragma-dialectics.

AbstractLGBTQ+ individuals experience health care disparities and difficulty accessing affirming care. Little is known regarding the health and experiences among subpopulations of specific sexual orientations and gender identities (SOGI). We implemented the first LGBTQ + health needs assessment survey in Nassau and Suffolk Counties, New York, to assess individuals’ health care experiences, behaviors, access to care, and health care needs. The sample (N = 1150) consisted of many SOGI subgroups. Greater than 60% of respondents reported symptoms of chronic depression; over one third reported disrespectful health care experiences; and two thirds experienced verbal harassment. Bisexual/bicurious, pansexual, queer, gender nonconforming and transgender individuals experienced highest rates of mental health concerns and difficulty accessing care. Behavioral health concerns were also high among Black, multiracial, Hispanic, Asian, young adult, and lower-income respondents. Gaining an understanding of unique differences among LGBTQ+ subgroups can guide implementation of services targeting specific subpopulations to improve access to care and reduce disparities.
Reducing the Individual Carbon Impact of Video Streaming: A Seven-Week Intervention Using Information, Goal Setting, and Feedback

Published: February 2023

AbstractThis online intervention study examined whether system- and action-related information alone, together with goal setting, or together with goal setting and feedback helps people change their video streaming activities in a pro-environmental way. The participants (N = 92) documented their video streaming activities for one week prior to the intervention (week 1), three weeks after the onset of the intervention (weeks 2–4), and in a follow-up period two weeks later (week 7). A reduction of greenhouse gas emissions associated with video streaming was observed over the course of the intervention, together with reduced streaming durations and lowered resolution settings across all groups. There were no differences between the groups. It appears that as regards video streaming, information combined with self-monitoring has considerable potential to change individual behaviour and its associated ecological impact.
Idleness as work? How public defenders do their job by waiting
Authors: Ang Milena 
Published: February 2023

AbstractHow can public defenders provide adequate legal representation when they are underbudgeted and overworked? Mexican public defenders represent 75-90% of those facing a judicial process (either through the entire process or at some points of it) and receive around one tenth of the budget allocated for their counterparts, prosecutors or fiscalías. Drawing from fieldwork conducted in Oaxaca city, Mexicali, and Tijuana, I find that the public defenders spend a considerable amount of time waiting: waiting in the office for their next case to be assigned, waiting to receive a file, or waiting for the judge to show up in court. Although superficially this waiting can be interpreted as idleness, I identify three ways in which defenders do their jobs during their down-time. First, they interchange key information about specific cases with other operators of the system and families and acquaintances of the accused, thus building legal strategies. Second, down time allows them to socialize with agents of the fiscalía, cops, and other courthouse workers, a crucial activity for the establishment of cordial interagency relations. Finally, they also use this down time to do what I call “forced encroachment,” meaning the undertaking of activities—such as professionalization of legal translators—that are not necessarily their responsibility but that are nevertheless crucial for the jobs. Waiting, in a way, allows public defenders to provide a legal defense in the absence of time and money to investigate, thus keeping the criminal justice system running.
Intermediary liability and trade in follow-on innovation
Authors: Cuntz Alexander , Sahli Matthias 
Published: February 2023

AbstractIntellectual property rights have changed the market value and direction of artistic innovation throughout art history, in particular when new creations built on the art of predecessors. In this paper, we test how changes in legal frameworks and litigation risks affected market value and commercial trade around artistic reuses in the figurative arts and the ‘Appropriation Art’ movement in particular. Appropriation artists borrow images from different sources and incorporate them into new, derivative works of art. By doing so, they risk infringing copyright but also put auction trade and artwork availability at litigation risk as liability can extend to market intermediaries, such as auction houses, museums, or galleries. Using a differences-in-differences model and large-scale online data, we investigate the causal impact of the prominent Cariou v. Prince U.S. higher court decision on intermediary trade and the availability of artworks on sale in the Appropriation Art. As an exogenous shock, this decision changed the perceived litigation risk for market intermediaries around what constitutes fair use. Following the court decision, we find a temporary decline in the total number of global auctions in the Appropriation Art, a lower sales probability of these artworks, and a relocation of related auctions to non-U.S. houses.
Assessing bird habitat occupancy from gradient-based landscape metrics and principal polar spectral indices in the colombian andean region

Published: February 2023

Abstract
Context
The patch-mosaic model (PMM) is the most common way to describe the landscape in ecological research. Despite this, the gradient model (GM) was proposed as a more accurate representation of the heterogeneity of landscapes; however, little has been explored on the behavior and performance of continuous variables and surface-based metrics from GM under different analytical scenarios.

Objectives
We address the question: which landscape metrics, patch-based or surface-based, best explain habitat occupancy patterns of six bird species with different ecological preferences?

Methods
We generated detection histories for six bird species in a fragmented Andean landscape from Colombia. We obtain patch-based metrics from a land cover classification and surface-based metrics from the principal polar spectral indices (PPSi) to describe the landscape. Finally, we fitted dynamic occupancy models using variables derived from landscape models and compared their performance using quasi-AIC for each species.

Results
We obtained 909 detections for the six selected bird species. We found that PPSi and surface-based metrics were more informative when assessing occupancy patterns for five of the six species studied. In addition, surface-based metrics allowed to detect interspecific differences between species beyond an affinity for a particular cover type.

Conclusions
Surface-based metrics can be an alternative for assessing species response to landscape heterogeneity, particularly those that may be more sensitive to fine-scale changes in vegetation cover. However, there is no single “best” model to describe the landscape for all cases. PPSi can be very useful for land cover analysis in landscape ecology studies as an alternative to more popular vegetation indices.
Optimization of human gait using singular-value decomposition-based design variables
Authors: Guzelbulut Cem , Shimono Satoshi , Suzuki Katsuyuki 
Published: February 2023

AbstractAge, walking speed, the presence of walking problems, the slope of the ground, and many other parameters affect human gait. Understanding gait variations and obtaining a reference behavior under different conditions is important for identifying abnormal walking behaviors and designing walking assistive devices, orthoses, and prostheses. Predictive dynamics can be used to determine a reference motion for a given task. In the predictive dynamics approach, the motion of a human is generated using design variables, and the equation of motion is considered a constraint. Several design variables were used to generate the motion, and the biological limits of the joints were considered additional constraints in previous studies. A foot-ground contact model was used to generate vertical and horizontal ground reaction forces using the nonlinear spring-damper model. This study proposed a singular value decomposition-based joint angle generation method to reduce the number of design variables and additional constraints. First, the joint angles were calculated using the motion capture data of 225 participants. Then, a joint angle matrix containing the joint angles of all participants in the experiments was created. The modes of the joint angles were extracted using singular-value decomposition. The joint angles were generated by summing the multiplication of the first nine modes of the joint angles and their corresponding design variables. Therefore, the number of design variables was significantly reduced. Moreover, the constraints related to the joint angle limits were intrinsically satisfied. Joint angles, moments, and power were obtained for the optimal energy and moment square cases at different walking speeds. The optimal results were found to be consistent with experimental results in the literature.
Do students learn more from failing alone or in groups? Insights into the effects of collaborative versus individual problem solving in productive failure
Authors: Brand Charleen , Hartmann Christian , Loibl Katharina , Rummel Nikol 
Published: February 2023

AbstractProductive Failure (PF) is an instructional design that implements a problem-solving phase which aims at preparing students for learning from a subsequent instruction. PF has been shown to facilitate students’ conceptual knowledge acquisition in the mathematical domain. Collaboration has been described as a vital design component of PF, but studies that have investigated the role of collaboration in PF empirically so far, were not able to confirm the necessity of collaboration in PF. However, these studies have diverged significantly from prior traditional PF studies and design criteria. Therefore, the role of collaboration in PF remains unclear. In an experimental study that is based on the traditional design of PF, we compared a collaborative and an individual problem-solving setting. It was hypothesized that collaboration facilitates the beneficial preparatory mechanisms of the PF problem-solving phase: prior knowledge activation, awareness of knowledge gaps, and recognition of deep features. In a mediation analysis, the effects of collaborative and individual problem solving on conceptual knowledge acquisition as mediated through the preparatory mechanisms were tested. In contrast to the hypotheses, no mediations or differences between conditions were found. Thus, collaboration does not hold a major preparatory function in itself for the design of PF.
Dialysevorschrift
Authors: Pirklbauer Markus 
Published: February 2023

Zusammenfassung
Hintergrund
Empfehlungen für das intradialytische Elektrolytmanagement basieren derzeit ausschließlich auf Beobachtungsstudien, pathophysiologischen Überlegungen und Expertenmeinungen.

Fragestellung
Darstellung praxistauglicher Empfehlungen und Diskussion der zugrunde liegenden Evidenz für die Dialysevorschrift (Kalium, Natrium, Kalzium und Bikarbonat) bei chronischen Hämodialysepatient*innen mit und ohne Elektrolytstörungen.

Material und Methode
Bewertung der vorhandenen Studienlage und daraus abgeleiteter Therapieempfehlungen.

Ergebnisse
Der Einsatz niedriger Dialysatkaliumkonzentrationen ermöglicht eine adäquate Serumkaliumsenkung und geht bei hyperkaliämen chronischen Dialysepatient*innen nicht mit einem erhöhten kardiovaskulären Risiko einher. Die Verwendung fixer vs. individualisierter Dialysatnatriumkonzentrationen hat sich bei Normonatriämie bislang als gleichwertig erwiesen. Bei schwerer Hypo- bzw. Hypernatriämie können kontinuierliche Hämofiltrationsverfahren mit entsprechend adaptierter Substituatnatriumkonzentration eingesetzt werden. Alternativ können bei schwerer Hyponatriämie tägliche kurze Dialysesitzungen mit niedrigem Blutfluss und niedrigstmöglichem Dialysatnatrium verwendet werden. Intermittierende Dialyseverfahren sind bei schwerer Hypernatriämie kontraindiziert. Empfohlene Dialysatkalziumkonzentrationen (1,25–1,5 mmol/l) führen häufig zu intradialytischer Kalziumbeladung. Trotz der Empfehlung, Serumbikarbonatwerte von mehr als 22 mmol/l anzustreben, sollte aufgrund der Assoziation zwischen postdialytischer Alkalose und Mortalität eine Dialysatbikarbonatkonzentration von 35 mmol/l nicht überschritten werden.

Schlussfolgerungen
Randomisierte, kontrollierte Outcome-Studien sind notwendig, um die Dialysevorschrift im Hinblick auf das intradialytische Elektrolytmanagement zu optimieren.
