Authors: Wittek Agnes , Recker Florian , Neubacher Melissa , Siebers Pauline 
Published: August 2024

AbstractEffective healthcare relies on well-trained professionals, and the quality of their training is dependent on appropriate learning methods and assessment techniques. Gamification, the use of game mechanics in non-game environments, has emerged as a promising strategy in medical education. This review explores the applicability and effectiveness of gamification in obstetrics and gynecology education.Adhering to PRISMA guidelines, a comprehensive search was conducted on PubMed, Google Scholar, Embase, and Medline databases from January to March 2023. The search terms included “medical students OR residents OR physicians OR midwives AND games OR educational games OR serious games AND gynecology OR obstetrics”. The inclusion criteria encompassed studies published in English or German from 1990 to March 2023, focusing on gamification in gynecology and obstetrics education. Data extraction and analysis were structured using the PICOS framework.The review identified various studies demonstrating the effectiveness of gamification in obstetrics and gynecology education. Gaming shows like Jeopardy significantly boosted knowledge retention and engagement. VR technologies, such as Second Life, enhanced emergency and surgical training. Improvisational games improved empathy skills, though requiring reinforcement. Video games and laparoscopy trainers showed promise in enhancing surgical skills, with gamers performing better in initial tasks. Custom-developed games like Play and Learn for Surgeons significantly improved procedural skills.Gamification in obstetrics and gynecology education boosts learner engagement, knowledge retention, and practical skills. VR technologies and video games are effective for surgical training, while custom games can enhance specific procedural skills. Further research is needed to optimize and integrate gamification strategies into standard curricula, offering a modern approach to equip healthcare professionals with essential skills and knowledge.

Published: August 2024

Abstract
Background  Near-infrared fluorescence (NIRF) imaging using indocyanine green (ICG) allows perfusion to be visualized and objective perfusion parameters can be provided after additional measurements. Therefore, it has great potential in predicting adequate tissue perfusion. However, regarding bone tissue, evidence of the feasibility and usefulness of NIRF imaging using ICG is very limited.
Methods A prospective monocentric pilot study was carried out at a tertiary hospital in the Netherlands. Patients undergoing autologous breast reconstruction from August 2021 to August 2022 were included. During surgery, ICG (0.1 mg/kg) was injected intravenously and a fluorescent angiogram of 4 minutes was made directly after injection. Post hoc time-intensity curves were generated for a 5-mm region of interest (ROI) positioned on the cross-sectional lateral surface of the rib. The first moment of increase of intensity was defined as t0. Fluorescent parameters included ingress and egress of ICG.
Results Nine patients and 11 ribs were included for further analysis. Time-intensity curves were generated for endosteal measurement in 10 ribs. Three of the curves showed a steep and well-defined ingress and egress. In all other patients, the curves showed a much more flattened ingress and egress. Periosteal measurement was performed in nine ribs. No adverse events related to the ICG injection were observed intraoperatively.
Conclusion This feasibility study suggests that quantitative NIRF imaging using ICG can provide objective parameters of endosteal rib perfusion. Larger prospective series are needed to investigate the value of NIRF imaging using ICG to assess bone perfusion intraoperatively and to establish cutoff values for adequate bone perfusion.

Abstract
Background The timing of free flap reconstruction after lower extremity trauma has been a controversial debate since Marko Godina's original 72-hour recommendation. Recent advances in microsurgery warrant an evaluation of the optimal time to reconstruction.
Methods The Nationwide Readmission Database (2014–2019) was used to identify patients undergoing free flap reconstruction after lower extremity trauma. Risk-adjusted statistical methods were used to identify optimal time where risk of infectious and microsurgical complications increase and to quantify the risk associated with time delays.
Results A total of 1,030 patients undergoing reconstruction were identified. The mean time to flap coverage was 24.3 days. Thirty-three percent were performed within 72 hours, 24% from 72 hours to 10 days, 18% from 10 to 30 days, and 24% after 30 days. Flaps performed after 10 days were associated with increased risk of surgical site infection, osteomyelitis, and other wound complications, compared with those performed within 72 hours. There was no increased risk in the period of 72 hours to 10 days. Revision amputation and microsurgical complications were not increased after 10 days. The predicted optimal cutoff was 9.5 days for microsurgical complications and 14.5 days for infectious complications.
Conclusion Advances in microsurgery may be responsible for extending the time in which definitive soft tissue coverage is required for wounds resulting from lower extremity trauma. Although it appears the original 72-hour time window can be safely extended, efforts should be made to refer patients to specialty limb salvage centers in a timely fashion.
Computer-Aided Design and Manufacturing to Facilitate Microvascular Free Tissue Transfer in Extremity, Pelvic, and Spinal Reconstructions

Published: August 2024

Abstract
Background Numerous surgical fields have embraced computer-aided design and computer-aided manufacturing (CAD/CAM), including plastic and reconstructive surgery. However, most of the literature and clinical use pertains to reconstruction of the head and neck. Herein, we provide a case series and systematic review of the literature, documenting the use of CAD/CAM in facilitating complex microvascular free tissue transfer for reconstructions involving the extremities, pelvis, and spine (EPS).
Methods This study consisted of two components: a case series and a systematic review of the literature. For the case series, the senior author's cases that included CAD/CAM to assist microvascular free tissue transfer reconstructions of the EPS were included. For the systematic review, all PubMed-, Scopus-, and Google Scholar–indexed studies describing the use of CAD/CAM to facilitate free tissue transfer in the EPS were identified and included using PRSMA guidelines.
Results The case series identified 10 patients who received CAD/CAM-assisted microvascular reconstruction. Our systematic review identified 15 articles, representing 124 patients and 133 CAD/CAM-assisted free tissue transfers. Most authors believed that CAD/CAM facilitated a more efficient operation by shifting much of the intraoperative planning to the preoperative phase, ultimately translating to a shorter and more accurate surgery with improved function and cosmesis.
Conclusion CAD/CAM can be used to facilitate microvascular reconstruction of the EPS. Our cases series and systematic review suggest that CAD/CAM for EPS surgery may improve outcomes.
Discordant High Activated Partial Thromboplastin Time Relative to Anti-Xa Values in Hospitalized Patients is an Independent Risk Factor for Increased 30-day Mortality
Authors: Jin Jing , Gummidipundi Santosh , Hsu Joe , Sharifi Husham , Boothroyd Derek , Krishnan Anandi , Zehnder James L. 
Published: August 2024

Abstract
Background The activated partial thromboplastin time (aPTT) and anti-factor-Xa levels (anti-Xa) are both used to monitor patients on unfractionated heparin. Our previous study demonstrated that patients with discordant high aPTT relative to anti-Xa had higher rates of mortality and bleeding events.
Objective To determine if underlying patient characteristics drive both discordance and adverse outcomes or if discordance is an independent risk factor to adverse outcomes.
Methods We analyzed all patients hospitalized at the Stanford Hospital between January 2011 and December 2019 who had simultaneous aPTT and anti-Xa levels performed. From the electronic medical record, we extracted and analyzed 51 patient features including baseline coagulation laboratory results, demographics, values of other common laboratories (basic metabolic panel, complete blood count, etc.), diagnostic procedures, medications, and death.
Results A total of 17,728 patients had 78,701 paired aPTT and anti-Xa levels. Patients with discordant aPTT and anti-Xa where aPTT (seconds) was elevated beyond the expected therapeutic range had a higher 30-day mortality (odds ratio [OR]: 2.16, 95% confidence interval [CI]: 1.78–2.63, p < 0.001). Sectioning the patients based on the degree of discordance and whether aPTT or anti-Xa were signaling excess anticoagulation, we found those with an elevated aPTT discordant to their anti-Xa level had the highest odds of death (OR: 2.46, 95% CI: 1.99–3.10) compared with the concordant group. This finding was still present after controlling for patient comorbidity and other laboratory results at hospital admission.
Conclusion After controlling for patient features strongly associated with increased mortality in heparinized patients, we identified that the discordant pattern of high aPTT to anti-Xa served as an independent predictor of 30-day all-cause mortality, with a higher degree of discordance associated with increased odds of 30-day mortality.

Published: August 2024

Abstract
Introduction Binge-watching is a popular activity among people of all ages. It involves watching a television series or movies for a longer duration. The activity pleasures the viewers as it stimulates the “reward center” or “pleasure pathway” of the brain, which releases certain chemicals. However, excessive binge-watching can lead to internet addiction disorders, which is a growing concern among young people.
Objectives To address this concern, a study was conducted to identify binge-watching behavior and ways to overcome it among undergraduates in professional colleges.
Methodology The study involved 227 participants who were selected through a proportionate stratified simple random sampling technique. A descriptive survey design was adopted to collect data, and the participants were assessed using the “assessing binge-watching behavior—Binge-Watching Engagement and Symptoms Questionnaire” and a self-structured rating scale.
Results The results indicated that the majority of participants (78.9%) were engaged in binge-watching behavior. The highest percentage of binge-watching behavior was noted in the desire category (60.0%), and the lowest percentage was in positive emotions (44.0%). The mean percentages of dependency (57.7%) and loss of control (59%) were almost similar to the mean percentages of desire (60%) and engagement (59.2%). These results reflect the negative effects of binge-watching behavior. Moreover, the study revealed that 51.5% of binge-watchers were in the age group of 20 to 21 years, and 85% of them were female. This finding highlights the need to educate young people, particularly women, about the negative effects of binge-watching behavior.
Conclusion In conclusion, the study emphasizes the need to address the growing trend of binge-watching behavior among young people. The study recommends various strategies to overcome this behavior, such as limiting screen time, engaging in physical activities, and cultivating hobbies and interests.

Abstract
In this study, we investigate the use of two pairs of Russian prepositions—v‍/‍na (‘in/on’) and iz/s (‘from’) with the noun Ukraine in X discourse. Since Ukrainian independence in 1991, v Ukraine and iz Ukraine have been used to indicate Ukrainian sovereignty and na and s used as their unmarked counterparts as defined by Russian linguistic tradition. Using a web-based set of tools called TWIG, we examine how posts containing the prepositional phrases construct stances toward the Russian invasion of Ukraine. Specifically, we examine the frequency of the prepositional phrases, their collocations, and the semantics conveyed by the collocational patterns. Our findings show notable differences in the collocational patterns of posts using v Ukraine versus na Ukraine. Analysis of these collocations suggests that posts using v Ukraine have a proximation effect to the conflict, while those using na Ukraine have a distancing effect.

Abstract
This article reports on the linguistic and cultural adaptation of Items of the National Quality of Life Survey
(NQLS 2018), which are included in a National Survey that explores the availability of reasonable accommodation for Deaf users in
a health care setting as well as health care access. We document the cultural and linguistic adaptation step-by-step, guided by a
literature review, participatory group discussions, and qualitative testing. This research addresses the dearth of accessible
research instruments for D‍/‍deaf persons in low and middle-income countries. This lack of accessible tools leads to double layers
of exclusion, and data gaps often lead to erroneous generalizations that do not accurately represent D‍/‍deaf populations.
Evidence gaps may result in poor service planning and inadequate policymaking. This study contributes to good practices in
language interpreting in research settings, disability research, and global health.
Quantum geometric perspective on the origin of quantum-conditioned curvatures

Published: August 2024

Abstract
The quantization of the gravitational field, which includes the metric field, has been investigated using various methods such as loop quantum gravity, quantum field theory, and string theory. Nevertheless, an alternative strategy to tackle the challenge of merging the fundamentally different theories of general relativity (GR) and quantum mechanics (QM) is through a quantum geometric approach. This particular approach entails extending QM to relativistic energies and finite gravitational fields, while also expanding the continuous Riemann to a discretized (quantized) Finsler–Hamilton geometry. By embracing this method, it may be feasible to bridge the gap between GR and QM or even achieve their unification. The resulting fundamental tensor appears to blend its original classical and quantum characteristics, effectively integrating quantum-mechanically induced revisions to the affine connections and spacetime curvatures. Our study primarily focuses on investigating the Ricci curvature tensor in the context of the Einstein–Gilbert–Straus metric. By employing both analytical and numerical methods, we have identified quantum-conditioned curvatures (QCC) that act as additional sources of gravitation. These QCC exhibit a fundamental difference from the traditional curvatures described by Einsteinian GR. While the Ricci curvatures are predominantly positive across most regions, the quantized Ricci curvatures display negativity. We conclude that the QCC (a) possess an intrinsic, essential, and real character, (b) should not be disregarded due to their significant magnitude, and (c) are fundamentally different from the curvatures found in classical GR. Moreover, we conclude that the proposed quantum geometric approach may offer an alternative mathematical framework for understanding the emergence of quantum gravity.

Abstract
In the last few decades, interference has been extensively studied in both the quantum and classical fields, which reveals light volatility and is widely used for high-precision measurements. We have put forward the phenomenon in which the discrete diffraction and interference phenomena, presented by the time-varying voltage of a Su–Schrieffer–Heeger circuit model with an anti-PT (APT) symmetry. To demonstrate Young’s double-slit phenomenon in an APT circuit, we initially explore the coupled mode theory of voltage in the broken phase, observe discrete diffraction under single excitation and interference under double excitations. Furthermore, we design a phase-shifting circuit to observe the effects of phase difference and distance on discrete interference. Our work combines the effects in optics with condensed matter physics, show the Young’s double-slit phenomenon in electrical circuits theoretically and experimentally.

Published: August 2024

Abstract
We study a model of Ising spins in which direct exchange interactions compete with the Ruderman–Kittel–Kasuya–Yosida (RKKY) coupling, which may arise effectively from itinerant electrons. We consider the model in the two-dimensional square lattice and focus on values of the RKKY coupling constant (

J

RKKY

) and the Fermi momentum (

k
F

) that induce strong frustration. We study the low-temperature magnetic field phase diagram using Monte Carlo simulations, considering several nearest neighbors in the RKKY interaction. Magnetic frustration yields a rich phase diagram with a variety of exotic phases. We compute the structure factors and define appropriate order parameters to describe the transitions. We also discuss the validity of the approximation made for long-range couplings and analytically demonstrate the change in the coexistence lines in the phase diagram by including up to the tenth nearest neighbors.

Abstract
We report the synthesis, crystal structure, magnetization and specific heat studies of YCo3(OH)6.55Br2.45 single crystal. YCo3(OH)6.55Br2.45 crystallizes in trigonal structure, in which Co2+ ions form a perfect kagomé lattice. The magnetic susceptibility reveals successive magnetic transitions at 6.5 and 7.8 K and the Curie–Weiss fitting demonstrates that YCo3(OH)6.55Br2.45 has strong antiferromagnetic coupling and pronounced magnetic frustration effect. Specific heat data suggest that low-T magnetic transitions are attributed to antiferromagnetic ordering of Co2+ ions and the magnetic entropy points to effective 1/2 spin in the system. These results indicate that an unusual magnetic ordering state with effective spin-1/2 is realized in kagomé lattice system YCo3(OH)6.55Br2.45.
Depinning of charge density waves of different dimensionalities in 1T-TiSe2 and NbSe3

Abstract
Nonlinear transport behavior is one of the signatures of the formation of electronic crystals such as charge density wave (CDW), as it provides evidence for their collective motion. Such experimental evidence has been widely reported in quasi-one-dimensional (1D) materials but is rarely studied in 2D systems. Only a few studies on the RTe3 materials have been previsouly reported. Here we report for the first time the observation of CDW depinning and sliding in the layered 1T-TiSe2 compound, based on the observation of (1) nonlinear voltage-current characteristics and (2) the electrical noise, which are associated with the CDW depinning and sliding process. Similar measurements are also conducted on quasi-1D system NbSe3. The depinning behavior of the CDWs with different dimensionalities in these two systems are compared. It is found that the threshold electric field (E

T
) increases linearly with decreasing temperature for the 2D case, consistent with previous results on RTe3, while it demonstrated an activated behavior in 1D, as expected within the weak-pinning Fukuyama–Lee–Rice framework. Such a distinction of the threshold behavior in CDW systems of different dimensions therefore indicates a possible strong pinning picture in higher-dimensional CDW systems in general. E

T
is found to be much higher in 1T-TiSe2, consistent with a strong pinning picture, and could account for the scarcity of the depinning study in these 2D systems. Our results thus pave the way for a unified understanding of the CDW collective motion in different dimensionalities.
