Abstract

Context
Pituitary apoplexy (PA) has been traditionally considered a neurosurgical emergency, yet retrospective single-institution studies suggest similar outcomes among patients managed medically.

Objective
We established a multicenter, international prospective registry to compare presentation and outcomes in PA patients treated with surgery or medical management alone.

Methods
A centralized database captured demographics, comorbidities, clinical presentation, visual findings, hormonal status, and imaging features at admission. Treatment was determined independently by each site. Key outcomes included visual, oculomotor, and hormonal recovery, complications, and hospital length of stay. Outcomes were also compared based on time from symptom onset to surgery, and from admission or transfer to the treating center. Statistical testing compared treatment groups based on 2-sided hypotheses and P less than .05.

Results
A total of 100 consecutive PA patients from 12 hospitals were enrolled, and 97 (67 surgical and 30 medical) were evaluable. Demographics, clinical features, presenting symptoms, hormonal deficits, and imaging findings were similar between groups. Severe temporal visual field deficit was more common in surgical patients. At 3 and 6 months, hormonal, visual, and oculomotor outcomes were similar. Stratifying based on severity of visual fields demonstrated no difference in any outcome at 3 months. Timing of surgery did not affect outcomes.

Conclusion
We found that medical and surgical management of PA yield similar 3-month outcomes. Although patients undergoing surgery had more severe visual field deficits, we could not clearly demonstrate that surgery led to better outcomes. Even without surgery, apoplectic tumor volumes regress substantially within 2 to 3 months, indicating that surgery is not always needed to reduce mass effect.

Abstract
Various forms of artificial intelligence (AI) applications are being deployed and used in many healthcare systems. As the use of these applications increases, we are learning the failures of these models and how they can perpetuate bias. With these new lessons, we need to prioritize bias evaluation and mitigation for radiology applications; all the while not ignoring the impact of changes in the larger enterprise AI deployment which may have downstream impact on performance of AI models. In this paper, we provide an updated review of known pitfalls causing AI bias and discuss strategies for mitigating these biases within the context of AI deployment in the larger healthcare enterprise. We describe these pitfalls by framing them in the larger AI lifecycle from problem definition, data set selection and curation, model training and deployment emphasizing that bias exists across a spectrum and is a sequela of a combination of both human and machine factors.

Published: September 2023

Background: The aim of this study was to collect and analyze the experiences in regard to the application of criminalistic and criminological protocols and procedures, which were used to carry out the intervention in the premises of Thomas Restobar in Peru, in the context of the declaration of sanitary measures to control COVID 19. This police intervention resulted in the death of 13 people. Methods: For the collection of information, we used the focus group technique, for which a script was designed and validated by five experts, considering six major subcategories: C1SC1: Joint investigation and prosecution work, C1SC2: Protocols and guidelines, C1SC3: Chain of custody (police, experts, and prosecutor), C1SC4: Quality of results; C2SC1: Participation of agents of Thomas Restobar and the municipality, C2SC2: Compliance with DIGESA-DIRIS health regulations. The study was approved by the Institutional Research Ethics Committee of the Universidad Norbert Wiener, with approval file N°864-2021. Results: From the criminological analysis it became evident that the deficiencies identified in the six structured subcategories have led to the tragic death of thirteen people from asphyxiation. The people who attended this bar did not comply with the sanitary norms, exposing the health and life of their relatives and other people. The security agents of the premises and of the Municipality of Los Olivos did not comply with the norms of supervision and control, which finally led to the unfortunate death of 13 people from asphyxiation, closely related to the case of Utopia, in 2002. Conclusions: When evaluated by the experts of the focus group, it has generated two emerging categories: creation of a School of Experts and the categorization of the experience, which would prevent cases like Utopia and Thomas Restobar from happening again.

Published: September 2023

Background: Suitable aortic neck is one of the essential components for thoracic endovascular aortic repair (TEVAR) and endovascular aortic repair (EVAR). Advanced techniques were developed to adjust and compromise the aneurysm neck angulation but with adding additional devices and complexity to the procedure. We proposed a simple technique to modify severe neck angulation and/or iliac artery tortuosity by using the multiple stiff wire (MSW) technique. Method: Two femoral accesses were required for the MSW technique. A guidewire with a support catheter was inserted through the right and left femoral arteries and positioned in the abdominal or thoracic aorta. Wire exchanges were done with extra stiff wire in both femoral accesses. It can be considered to add multiple stiff wires to align the torturous neck / iliac artery. Delivery of the stent graft main body can be done via one of the accesses. Result: Six patients with different aortic pathology were admitted to our hospital. Four patients undergo EVAR procedure and two patients undergo TEVAR procedure. All patients had aortic neck angulation problems with one patient having iliac artery tortuosity. MSW technique was performed on the patients with good results. Follow-up CTA after 3 months revealed a good stent position without stent migration and no endoleak was found in all but one patient. Conclusion: MSW technique is a simple and effective technique to modify aortic neck/artery angulation in TEVAR or EVAR procedure.
Bounds on the Optimal Radius When Covering a Set with Minimum Radius Identical Disks
Authors: Birgin Ernesto G. , Gardenghi John L. , Laurain Antoine 
Published: September 2023

The problem of covering a two-dimensional bounded set with a fixed number of minimum-radius identical disks is studied in the present work. Bounds on the optimal radius are obtained for a certain class of nonsmooth domains, and an asymptotic expansion of the bounds as the number of disks goes to infinity is provided. The proof is based on the approximation of the set to be covered by hexagonal honeycombs and on the thinnest covering property of the regular hexagonal lattice arrangement in the whole plane. The dependence of the optimal radius on the number of disks is also investigated numerically using a shape-optimization approach, and theoretical and numerical convergence rates are compared. An initial point construction strategy is introduced, which, in the context of a multistart method, finds good-quality solutions to the problem under consideration. Extensive numerical experiments with a variety of polygonal regions and regular polygons illustrate the introduced approach.

BackgroundThe Ascertain Dementia 8-item Questionnaire (AD8) is a screening tool for cognitive impairment that can be administered to older persons and/or their informants.ObjectivesTo evaluate the diagnostic accuracy and compare the predictive parameters of the informant and participant-completed Ascertain Dementia 8-item Questionnaire (iAD8 and pAD8, respectively) in older adults with cognitive impairment.Methods/DesignWe searched ten electronic databases (including MEDLINE (Ovid), Embase) from tool inception to March 2022. We included studies with patients ≥60 years old that were screened for cognitive impairment using AD8 in any healthcare setting. Predictive parameters were assessed against reference standards to estimate accuracy and diagnostic ability using bivariate random-effects meta-analyses. We used QUADAS-2 criteria to assess risk of bias.ResultsA cut-off of ≥2/8 was used to classify mild cognitive impairment (MCI), dementia, and cognitive impairment (MCI or dementia). Seven studies using the iAD8 (n = 794) showed a sensitivity of 80% and specificity of 79% to detect MCI. Nine studies using the iAD8 (n = 2393) established 91% sensitivity and 64% specificity to detect dementia. To detect MCI using the pAD8, four studies (n = 836) showed 57% sensitivity and 71% specificity. To detect dementia using the pAD8, four studies (n = 3015) demonstrated 82% sensitivity and 75% specificity. Recurring high or unclear risk of bias was noted in the domains of “Index test” and “reference standard”.ConclusionsThe diagnostic accuracy of iAD8 is superior to that of pAD8 when screening for cognitive impairment. The AD8 may be an acceptable alternative to screen for cognitive impairment in older adults when there are limitations to formal testing.
Postdemokratie als Problematisierungskonzept
Authors: Wille Katrin 
Published: September 2023

Abstract
Comparing Rancière’s and Crouch’s respective concepts of post-democracy and the way they problematise the state of contemporary (Western) societies, this article opts for a third way to state the problem, associated with the idea of democracy as a form of life. Common to all three approaches is the critique of an ‘engineering attitude’ that conceives problems as disturbances that have merely to be fixed. All three also warn against the dominant influence of economics in politics and the increase of right-wing populism. However, they diverge in their basic understanding of what problems are and how they are constituted. This article will show that the way we conceive the notion of a problem itself has important implications for our understanding of the problems of democracy and our engagement with them.
Pragmatistische Kritik der Postdemokratie
Authors: Reder Michael 
Published: September 2023

Abstract
Post-democracy has become an important contribution to the discourse on democratic theory. On the one hand, this article appreciates the impulses opened up by the diagnosis of post-democracy. On the other hand, it criticizes some problematic presuppositions. Especially the thesis of post-democracy seems to imply an ideal of democracy that is oriented toward a certain type of democracy, without critically discussing it. The tradition of philosophical pragmatism is drawn upon to show how an alternative critical diagnosis of democracy might look. The pragmatist tradition, it is argued, avoids the problems of the diagnosis of post-democracy outlined and develops a normatively grounded concept of democracy. The normative aim of democracy consists in focusing on the experience of vulnerability in the face of violence and suffering. Thus, democracy should be conceptualised as a reflexive practice that asks how to deal with these experiences of vulnerability.

Published: September 2023

Abstract
The effects of steam explosion (SE) on the physicochemical, functional and structural characteristics of soluble dietary fiber (SDF) extracted from pomelo peel were evaluated. At the treatment condition of 0.9 MPa,120 s, the extraction yield of SDF increased by 156.7 %, and the water holding capacity, oil holding capacity, and swelling capacity increased by 36.6 %, 42.7 %, and 21.4 %, respectively. Additionally, in vitro hypoglycemic capacity, cation exchange capacity, nitrite ion adsorption capacity, and antioxidant capacity were all improved. It was observed that a large number of cracks in the SDF, and the structure of SDF became loose and porous and specific surface area of SDF increased to 1.41 times. In addition, the results from differential scanning calorimetry indicated that SDF treated with SE had better thermal stability, and the degradation temperature increased from 311.93 °C to 316.28 °C. So, SE could be used as an effective method for modifying dietary fiber.

Published: September 2023

Abstract
The goal of the current work was to develop and validate web-based measures for assessing English vocabulary knowledge. Two existing paper-and-pencil assessments, the Vocabulary Size Test (VST) and the Word Familiarity Test (WordFAM), were modified for web-based administration. In Experiment 1, participants (n = 100) completed the web-based VST. In Experiment 2, participants (n = 100) completed the web-based WordFAM. Results from these experiments confirmed that both tasks (1) could be completed online, (2) showed expected sensitivity to English frequency patterns, (3) exhibited high internal consistency, and (4) showed an expected range of item discrimination scores, with low frequency items exhibiting higher item discrimination scores compared to high frequency items. This work provides open-source English vocabulary knowledge assessments with normative data that researchers can use to foster high quality data collection in web-based environments.

Targeting PTBP1 blocks glutamine metabolism to improve the cisplatin sensitivity of hepatocarcinoma cells through modulating the mRNA stability of glutaminase
Authors: Tian Ruimin , Li Yanfei , Shen Xiaojie , Li Ying 
Published: September 2023

Abstract
Hepatocellular carcinoma (HCC) is a frequently diagnosed malignancy with a high mortality rate. Cisplatin (CDDP) is a widely applied anti-cancer drug. However, a large population of liver cancer patients developed CDDP resistance. The polypyrimidine tract binding protein (PTBP1) is an RNA-binding protein involving in progressions of diverse cancers. Here we report PTBP1 was significantly upregulated in liver tumors and cell lines. Silencing PTBP1 effectively sensitized HCC cells to CDDP. From the established CDDP-resistant HCC cell line (HepG2 CDDP Res), we observed that CDDP-resistant cells were more sensitive to CDDP under low glutamine supply compared with that in HCC parental cells. CDDP-resistant HCC cells displayed elevated glutamine metabolism rate. Consistently, PTBP1 promotes glutamine uptake and the glutamine metabolism key enzyme, glutaminase (GLS) expression. Bioinformatics analysis predicted that the 3′-UTR of GLS mRNA contained PTBP1 binding motifs which were further validated by RNA immunoprecipitation and RNA pull-down assays. PTBP1 associated with GLS 3′-UTR to stabilize GLS mRNA in HCC cells. Finally, we demonstrated that the PTBP1-promoted CDDP resistance of HCC cells was through modulating the GLS–glutamine metabolism axis. Summarily, our findings uncovered a PTBP1-mediated CDDP resistance pathway in HCC, suggesting that PTBP1 is a promisingly therapeutic target to overcome chemoresistance of HCC.

Abstract
The twofold purpose of this study was to: (a) analyze Physical Education Teacher Education (PETE) students’ self-efficacy in teaching students with disabilities and (b) examine similarities and differences in PETE students’ self-efficacy toward teaching students with disabilities between South Korea and the United States (U.S.). Grounded in self-efficacy theory, the research design was a multiple-case study. The participants were undergraduate PETE students from South Korea (n = 8 Korean students, 6 men and 2 women) and the U.S. (n = 6 White students, 5 men and 1 women). Purposive (criterion) sampling was used identifying and recruiting participants. The data sources were a demographic questionnaire and interviews via Zoom technology. The data were analyzed using within-case analysis and cross-case analysis. Four major themes were exposed, which were: (a) self-efficacy differed, (b) school-based experiences, (c) education and rights, and (d) feelings and reactions. Further, there were similarities and differences in the participants’ experiences. We discussed these findings and the implications.
A novel method for measurements of surface topography in previously inaccessible areas
Authors: Becker Nils , Ulrich Carsten , Körner Chris , Schlecht Berthold 
Published: September 2023

Abstract
Since mechanical properties of parts in mechanical engineering are influenced in many ways by their surface structure, detailed knowledge of the surface structure is essential for predicting and describing these properties. Tactile and optical measurement methods are well established but cannot always reach every area of a part due to geometric constraints. To enable measurements in these areas, a method utilizing impressions and a laser scanning microscope is proposed. It is easy to use and able to correctly reproduce surface structures of technical surfaces, which is proven by a comparison of original parts and impressions of three surface areas on an example specimen. Two application examples from the domain of fatigue strength tests are shown. The surface structure is measured directly in the notch radius of shaft shoulders and inside hollow shafts made in different manufacturing processes. Utilizing modern optical measurement instruments, the proposed method enables accurate measurements of surface structure in previously inaccessible areas.
Die Erkenntnisgrenzen einer rein monetären Wirtschaftstheorie
Authors: Schröder Adrian 
Published: September 2023

Zusammenfassung
Im Beitrag „Was ist Modern Monetary Theory?“ haben Dirk Ehnts und Maurice Höfgen (2022) in dieser Zeitschrift die derzeit viel erörterte gleichnamige Geldtheorie präsentiert. Adrian Schröder findet ihre Ausführungen nicht überzeugend. Er kritisiert den Beitrag besonders in Hinblick auf die Thesen, es gebe kein Problem der Staatsfinanzierung, die staatliche Geldschöpfung sei nur durch selbstgewählte Restriktionen begrenzt und die Verwendung von Geld gehe auf die Verpflichtung privater Akteure zurück, Steuern zu zahlen. Als fundamentalen Unterschied zwischen gängiger ökonomischer Theoriebildung und Modern Monetary Theory (MMT) arbeitet er heraus, dass Letztere die monetären Ströme analytisch von ihren realwirtschaftlichen Implikationen trennt.
Mortuary palisades, single graves and cultural admixture: The establishment of Corded Ware culture on the Jutland Peninsula
Authors: Nielsen Simon K. , Johannsen Niels N. 
Published: September 2023

Abstract
The emergence and nature of the supra-regional Corded Ware complex in the 3rd millennium BCE is a longstanding, classical question in European archaeology. While recent genomic and genome-wide aDNA analyses have shown that migration was part of the process by which this phenomenon spread across a vast part of Central and northern Europe, the archaeological record of the same area makes equally clear that the character of its more specific regional manifestations was not uniform. This combination calls for renewed regional studies aimed at understanding the pre-existing contexts, the situated processes and the variable outcomes of this new cultural formation, taking a contribution of migration as a starting premise rather than an explanatory end goal. This article presents such a study, focusing on a particular aspect of the so-called Single Grave burial custom on the Jutland Peninsula, which constitutes the most obvious element of Corded Ware culture in the region. Dating to the early part of this tradition (c. 2850–2600 BCE), circular arrangements of wooden posts or planks lodged vertically in a ditch to form a circular palisade are frequently found encircling a contemporaneous human grave. Here, we provide the first systematic study of these structures, which we argue are most meaningfully referred to as mortuary palisades. We present their distribution, chronology and basic morphology as well as their association with graves and relation to burial mounds, leading to a discussion of their probable ritual function in connection with a particular, processual understanding and handling of death. Based on this general presentation, we then analyse geographical variation in the manifestation of the mortuary palisade custom and discuss potentially underlying causes, emphasizing widely differing degrees of cultural admixture of Corded Ware culture and local, pre-existing traditions and preferences in different parts of the Jutland Peninsula.
