Anesthetic Management of Adults With Epidermolysis Bullosa
Authors: Mittal Brita M. , Goodnough Candida L. , Bushell Erin , Turkmani-Bazzi Sophia , Sheppard Kelly
Published: August 2021

Epidermolysis bullosa (EB) is a group of rare, inherited diseases characterized by skin fragility and multiorgan system involvement that presents many anesthetic challenges. Although the literature regarding anesthetic management focuses primarily on the pediatric population, as life expectancy improves, adult patients with EB are more frequently undergoing anesthesia in nonpediatric hospital settings. Safe anesthetic management of adult patients with EB requires familiarity with the complex and heterogeneous nature of this disease, especially with regard to complications that may worsen during adulthood. General, neuraxial, and regional anesthetics have all been used safely in patients with EB. A thorough preoperative evaluation is essential. Preoperative testing should be guided by EB subtype, clinical manifestations, and extracutaneous complications. Advanced planning and multidisciplinary coordination are necessary with regard to timing and operative plan. Meticulous preparation of the operating room and education of all perioperative staff members is critical. Intraoperatively, utmost care must be taken to avoid all adhesives, shear forces, and friction to the skin and mucosa. Special precautions must be taken with patient positioning, and standard anesthesia monitors must be modified. Airway management is often difficult, and progressive airway deterioration can occur in adults with EB over time. A smooth induction, emergence, and postoperative course are necessary to minimize blister formation from excess patient movement. With careful planning, preparation, and precautions, adult patients with EB can safely undergo anesthesia.

Background: The yellow mealworm beetle, Tenebrio molitor, is a promising alternative protein source for animal and human nutrition and its farming involves relatively low environmental costs. For these reasons, its industrial scale production started this century. However, to optimize and breed sustainable new T. molitor lines, the access to its genome remains essential.

Methods: By combining Oxford Nanopore and Illumina Hi-C data, we constructed a high-quality chromosome-scale assembly of T. molitor. Then, we combined RNA-seq data and available coleoptera proteomes for gene prediction with GMOVE.

Results: We produced a high-quality genome with a N50 = 21.9Mb with a completeness of 99.5% and predicted 21,435 genes with a median size of 1,780 bp. Gene orthology between T. molitor and Tribolium castaneaum showed a highly conserved synteny between the two coleoptera.

Conclusions: The present genome will greatly help fundamental and applied research such as genetic breeding and will contribute to the sustainable production of the yellow mealworm.
A new Sense of Responsibility? A Levinasian Ecology of Religious Sentiment
Authors: Dickinson Colby
Published: August 2021

The aim of this essay is to look at the manner in which the philosophical ethics of Emmauel Levinas can be brought into dialogue with environmental ethics and animal rights. Though his work has often been seen as being at odds with environmental concerns is general, I wish to highlight a basic portraiture of what Levinas' ethics of responsibility and substitution might look like within such a context and to point out the deep resonance which his work has with other recent philosophical attempts to develop similar lines of environmental responsibility. In the end, this essay tries to point such Levinasian insights beyond Levinas' own approach and toward a reckoning with a more 'object oriented' approach to our most fundamental ethical concerns today. Though this presentation will certainly challenge the standard Levinasian division between moral subjects and their objects, such reasoning, it is argued, is beneficial not only for ethical quandaries, but also for re-conceiving the nature of the human-being in its interconnectedness to the environment around it.
‘Psychic Screams’: Reflections on a Howard Thurman Sermon
Authors: Lyons Ivory
Published: August 2021

The 20th century mystic/writer Howard Thurman makes a claim that there is a symbiotic relationship between the earth adn humans such that what humans experience as violence against each other is actually a reflection of the violence that humans do to the earth. The major contentions of this paper are (i) the curse as laid out in Genesis assumes that there is an intended harmony between the various elements of creation, but this harmony was disrupted ultimately by human mistrust of the divine; and (ii) that healing is possible if humans learn how to live in peace with the Earth. The paper will also explore possible ramifications for human life and for spiritual life on this plant if indeed this is the sort of harmony envisioned or entrusted to humans, animals and plant life.
Meeting of Asia and the Netherlands: On Van Gogh’s Challenge in Emulating Rembrandt
Authors: Akihiro Ozaki
Published: August 2021

The essay grew out of an issue I had been pondering for some time and is an attempt to gain an insight into a secret Van Gogh was eager to discover while comparing himself as an artist with “Rembrandt, the magician”. Van Gogh was convinced that art could succeed where religion had failed. Moreover, there was no need for art to be directly connected with Christianity as a system. For Van Gogh, in this frame of mind, the art of “Japan”, as exemplified by the genre of ukiyo-e, and such like, provided hope. Rembrandt, too, saw oriental art not so much as art in itself but as a method of expressing one’s innermost feelings that were still lacking in European art, and that were, moreover, understood as a source of inspiration for the creation of a new, ideal form of human compassion. Similarly, Van Gogh's art was distilled into a more essential form of itself as his inspiration from the ukiyo-e genre gradually deepened and became more internalized. Therefore, this is something he shared with Rembrandt and related him more closely to the oriental art apparent in work of the Old Master.
Supply Chain Coordination for E-Commerce: Risk Penalty vs. Flat Rate
Authors: Song Ju Myung , Zhao Yao
Published: August 2021

Problem definition: We study the coordination of an E-commerce supply chain between online sellers and third party shippers to meet random demand surges, induced by, for instance, online shopping holidays. Academic/practical relevance: Motivated by the challenge of meeting the unpredictable demand surges in E-commerce, we study shipping contracts and supply chain coordination between online sellers and third party shippers in a novel model taking into account the unique features of the shipping industry. Methodology: We compare two shipping contracts: the risk penalty (proposed by UPS) and the flat rate (used by FedEx), and analyze their impact on the seller, the shipper, and the supply chain. Results: Under information symmetry, the sophisticated risk penalty contract is no better than the simple flat rate contract for the shipper, against common belief. Although both the risk penalty and the flat rate can coordinate the supply chain, the risk penalty does so only if the shipper makes zero profit, but the flat rate can provide a positive profit for both. These results represent a new form of double marginalization and risk-sharing, in sharp contrast to the well-known literature on the classic supplier-retailer supply chain, where risk-sharing contracts (similar to the risk penalty) can bring benefits to all parties, but the single wholesale price contract (similar to the flat rate) can achieve supply chain coordination only when the supplier makes zero profit. We also find that only the online seller, but not the shipper, has the motivation to vertically integrate the seller-shipper supply chain. Under information asymmetry, however, the risk penalty brings more benefit to the shipper than the flat rate, but hurts the seller and the supply chain. Managerial implications: Our results imply that information plays an important role in the shipper’s choices of shipping contracts. Under information symmetry, the risk penalty is unnecessarily complex because the simple flat rate is as good as the risk penalty for the shipper; moreover, it is better for the seller-shipper coordination. However, under information asymmetry, the shipper faces additional shipping risk that can be offset by the extra flexibility of the risk penalty. Our study also explains and supports the recent practice of online sellers (e.g., Amazon.com and JD.com), but not shippers, to vertically integrate the supply chain by consistently expanding their shipping capabilities.
Common haemostatic techniques used in surgical practice
Authors: Frew Georgina H , Dick Lachlan , Young Jamie
Published: August 2021

Intraoperative bleeding can be difficult to manage and is associated with worse patient outcomes. Good intraoperative haemostasis by the surgeon is a key factor in ensuring a bloodless field and reducing intraoperative blood loss. There is a myriad of mechanical, thermal and energy-based techniques available to use, each of which has their own benefits and drawbacks. The decision of which to use will depend on patient and procedural factors as well as the surgeon's preference. This article reviews techniques commonly used in surgical practice to maintain intraoperative haemostasis.

Authors: Martin John R. , Saunders Patrick E. , Phillips Mark , Mitchell Sean M. , Mckee Michael D. , Schemitsch Emil H. , Dehghan Niloofar
Published: August 2021

Aims

The aims of this network meta-analysis (NMA) were to examine nonunion rates and functional outcomes following various operative and nonoperative treatments for displaced mid-shaft clavicle fractures.

Methods

Initial search strategy incorporated MEDLINE, PubMed, Embase, and the Cochrane Library for relevant randomized controlled trials (RCTs). Four treatment arms were created: nonoperative (NO); intramedullary nailing (IMN); reconstruction plating (RP); and compression/pre-contoured plating (CP). A Bayesian NMA was conducted to compare all treatment options for outcomes of nonunion, malunion, and function using the Disabilities of the Arm Shoulder and Hand (DASH) and Constant-Murley Shoulder Outcome scores.

Results

In all, 19 RCTs consisting of 1,783 clavicle fractures were included in the NMA. All surgical options demonstrated a significantly lower odds ratio (OR) of nonunion in comparison to nonoperative management: CP versus NO (OR 0.08; 95% confidence interval (CI) 0.04 to 0.17); IMN versus NO (OR 0.07; 95% CI 0.02 to 0.19); RP versus NO (OR 0.07; 95% CI: 0.01 to 0.24). Compression plating was the only treatment to demonstrate significantly lower DASH scores relative to NO at six weeks (mean difference -10.97; 95% CI -20.69 to 1.47).

Conclusion

Surgical fixation demonstrated a lower risk of nonunion compared to nonoperative management. Compression plating resulted in significantly less disability early after surgery compared to nonoperative management. These results demonstrate possible early improved functional outcomes with compression plating compared to nonoperative treatment. Surgical fixation of mid-shaft clavicle fractures with compression plating may result in quicker return to activity by rendering patients less disabled early after surgery.

Photonic instantaneous frequency measurement using a dense wavelength-division multiplexer
Authors: Li Xiangrui , Wen Aijun , Li Xiaoyang , Mo Yinglun , Zhuo Hao
Published: August 2021

A photonic instantaneous frequency measurement receiver based on frequency to optical power mapping is proposed and experimentally demonstrated. One channel of a dense wavelength-division multiplexer (DWDM) is used as an optical filter to establish a power ratio function related to the frequency of the microwave signal. Different from most optical filters, the DWDM filter features smooth and quasilinear roll-off over a wide bandwidth. With the help of a laser of good wavelength stability and a bias controller, large measurement range and high accuracy are simultaneously achieved without multi-step operation. The instanstaneous frequency measurement receiver can measure the frequency with an accuracy of 0.2% of the signal frequency in the range of 1–40 GHz over 1.5 h in the experiment.
Influence of jet components on the aero-optical effects of a 3D supersonic mixing layer
Authors: Xing Boyang , Zhang Bin , Guo Guangming , Li Dongdong , Liu Hong
Published: August 2021

Aero-optical effects in the mixing layer have caused significant concern due to the negative influence of high-speed vehicles with infrared imaging guidance systems. Here, we study the influence of different cooling mediums on the aero-optical effects. Four different cooling components are considered: helium (He), nitrogen (

N

2

), air, and argon (Ar). The large eddy simulation method and ray-tracing method are used, respectively, to simulate the 3D mixing layer and to calculate the optical path difference (OPD). The numerical results show that, as the molecular weight of the cooling mediums increases, the mixing layer transition advances and the 3D effect of the flow field is enhanced. The local minimum OPD values of the wavefront distortion are significantly correlated with the large-scale vortex structure of the mixing layer. The compression effect plays a dominant role in aero-optics before the large-scale structure forms. Once the large-scale vortex structure generates, the aero-optical effect is conducted by the density and compression effect. The cooling medium helium delays the development of the mixing layer and subsequently reduces the aero-optical effects. However, once the large-scale vortex structure forms, the aero-optical effect becomes serious due to the largest density difference between air and He.

DETECTOR: structural information guided artifact detection for super-resolution fluorescence microscopy image
Authors: Gao Shan , Xu Fan , Li Hongjia , Xue Fudong , Zhang Mingshu , Xu Pingyong , Zhang Fa
Published: August 2021

Super-resolution fluorescence microscopy, with a spatial resolution beyond the diffraction limit of light, has become an indispensable tool to observe subcellular structures at a nanoscale level. To verify that the super-resolution images reflect the underlying structures of samples, the development of robust and reliable artifact detection methods has received widespread attention. However, the existing artifact detection methods are prone to report false alert artifacts because it relies on absolute intensity mismatch between the wide-field image and resolution rescaled super-resolution image. To solve this problem, we proposed DETECTOR, a structural information-guided artifact detection method for super-resolution images. It detects artifacts by computing the structural dissimilarity between the wide-field image and the resolution rescaled super-resolution image. To focus on structural similarity, we introduce a weight mask to weaken the influence of strong autofluorescence background and proposed a structural similarity index for super-resolution images, named MASK-SSIM. Simulations and experimental results demonstrated that compared with the state-of-the-art methods, DETECTOR has advantages in detecting structural artifacts in super-resolution images. It is especially suitable for wide-field images with strong autofluorescence background and super-resolution images of single molecule localization microscopy (SMLM). DETECTOR has extreme sensitivity to the weak signal region. Moreover, DETECTOR can guide data collection and parameter tuning during image reconstruction.
