Published: April 2023

AbstractMega-urban regions (MURs) are important consumers or traders of resources from, or producers of wastes destined for, the global hinterlands. These roles, coupled with their concentration, clustering and centrality effects, mean MURs have a disproportionately large effect on the sustainability of global production-consumption systems (PCSs). Actions taken within MURs influence the sustainability of global PCSs, and vice versa; but that influence is complicated by complex governance intersections. Three cases are used to illustrate governance innovation in MUR-PCS interactions: industrial symbiosis in Tianjin, China; electricity production in London, UK; and the adoption of standards and labels for seafood in Bangkok, Thailand. In London and Tianjin, waste capture reduced consumption of hinterland resources, whereas in Bangkok, the aim was to improve the sustainability of resource use in coastal and marine hinterlands. We suggest an agenda for research to evaluate the potential for transferrable MUR governance innovation to enable sustainable and equitable PCSs.
Trade policy announcements can increase price volatility in global food commodity markets
Authors: Brander Michael , Bernauer Thomas , Huss Matthias 
Published: April 2023

AbstractMany countries use trade policy to insulate their domestic markets from price volatility. However, there is a widespread concern that such policies—particularly export restrictions—may amplify global price volatility, adversely affecting other countries. Here, using an original dataset on trade policy announcements on wheat and maize encompassing the food price crises of 2007–2008 and 2010–2011, we show that the announcement of trade policy changes can increase global price volatility. This effect applies not only to export restrictions but also to import liberalization measures and is most pronounced when markets are tight (stocks are low). Policymakers should work towards increasing stock levels to mitigate price volatility effects of trade policy changes. When markets are tight, export restrictions and import liberalizations should be avoided.

Context. High-redshift galaxies are expected to be more turbulent than local galaxies because of their smaller size and higher star formation and thus stronger feedback from star formation, frequent mergers events, and gravitational instabilities. However, this scenario has recently been questioned by the observational evidence of a few galaxies at z ∼ 4 − 5 with a gas velocity dispersion similar to what is observed in the local population.
Aims. Our goal is to determine whether galaxies in the first billion years of the Universe have already formed a dynamically cold rotating disk similar to the local counterparts.
Methods. We studied the gas kinematic of 22 main-sequence star-forming galaxies at z > 5 and determined their dynamical state by estimating the ratio of the rotational velocity and of the gas velocity dispersion. We mined the ALMA public archive and exploited the [C II] and [O III] observations to perform a kinematic analysis of the cold and warm gas of z > 5 main-sequence galaxies. We compared our results with what was found in the local and distant Universe and investigated the evolution of the gas velocity dispersion with redshift. We also compared the observations with theoretical expectations to assess the main driver of the gas turbulence at z > 5.
Results. The gas kinematics of the high-z galaxy population observed with ALMA is consistent within the errors with rotating but turbulent disks. We indeed infer a velocity dispersion that is systematically higher by 4–5 times than the local galaxy population and the z ∼ 5 dust-obscured galaxies reported in the literature. The difference between our results and those reported at similar redshift can be ascribed to the systematic difference in the galaxy properties in the two samples: the disks of massive dusty galaxies are dynamically colder than the disks of dust-poor galaxies. The comparison with the theoretical predictions suggests that the main driver of the velocity dispersion in high-redshift galaxies is the gravitational energy that is released by the transport of mass within the disk. Finally, we stress that future deeper ALMA high-angular resolution observations are crucial to constrain the kinematic properties of high-z galaxies and to distinguish rotating disks from kiloparsec-scale mergers.
Dépeindre la finance comme une « force pour le bien » : analyse de discours du Global Impact Investing Network (GIIN)

Published: April 2023

Cet article s’intéresse au discours de l’industrie de l’investissement d’impact à travers le cas du Global Impact Investing Network (GIIN), l’une des plus importantes organisations à faire la promotion de cette approche à travers le monde. À partir d’une analyse documentaire, nous décrivons le concept flou d’« investissement d’impact » qui se trouve au cœur de ce discours. Afin de favoriser la diffusion de ce concept et de son discours, le GIIN fait appel à deux techniques de « concrétisation » qui le rendent plus tangible : l’objectivation de l’impact social ou environnemental d’un investissement qui fait exister ce dernier à travers des mesures quantifiables et son exemplification, qui se focalise avant tout sur les investisseurs et leurs intentions plutôt que sur les entreprises bénéficiaires ou les populations et environnements visés in fine par ces investissements. Nous montrons enfin que ce concept est porté par un discours plus général qui est construit autour d’une logique dite « gagnant-gagnant ».

Abstract
Objectives The “marionette technique” for transumbilical laparoscopic cholecystectomy (m-TLC) offers improved cosmesis and possibly shorter postoperative recovery for patient undergoing laparoscopic cholecystectomy versus the four-port conventional laparoscopic cholecystectomy (CLC). We compared the outcomes of m-TLC and CLC at a tertiary care facility in New York.
Methods A retrospective chart review was conducted and data on patients who underwent m-TLC and CLC were retrieved. Hospital length of stay (LOS), operative time, and complications were compared between the two groups using linear and logistic regression, as appropriate.
Results M-TLC group patients were significantly younger, predominantly females with lower body mass index. They were less likely to have previous abdominal surgery and more likely to have noninflammatory pathology (p < 0.05 for all). Nonadjusted LOS (1 vs. 3 days, p-value < 0.0001) and operative time (50 vs. 56 minutes, p-value = 0.007) were significantly lower among patients who underwent m-TLC; however, there was no significant difference on multivariate analysis. In multivariate analysis, there was no difference in the overall complication rate (odds ratio: 1.63; 95% confidence interval 0.02–2.39).
Conclusion With careful patient selection, m-TLC offers better cosmesis with comparable safety outcomes.
Level of evidence Level III.

Authors: Lari Ali , Burhamah Waleed , Alherz Mohammad , Prada Carlos 
Published: April 2023

Abstract
Background Posttraumatic extensor carpi ulnaris (ECU) instability is an increasingly recognized cause of ulnar-sided wrist pain that occurs when the ECU subsheath is disrupted.
Purpose The purpose of this systematic review was to assess outcomes of operatively treated posttraumatic ECU instability.
Methods A systematic search of Medline, Embase, Web of Science, and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases was performed using “extensor carpi ulnaris” as the keyword. Studies were systematically screened and data extracted independently by two reviewers.
Results Eight retrospective studies met the inclusion criteria with a total of 97 wrists. The mean age was 32 years (13–61). Patients underwent either primary repair (40%) using sutures and anchors, or reconstruction (60%) using extensor retinaculum flaps. One study performed deepening of the osseous ulnar groove. Two studies compared preoperative and postoperative values. They both reported a significant improvement in pain scores, functional scoring instruments, satisfaction, and grip strength. The rest of the studies reported similarly favorable outcomes across the same outcomes. Concomitant pathologies were identified in 66% of the study population. Complications occurred in 9% of the sample size, including ECU tendinitis, ulnar sensory nerve irritation, and reintervention for concomitant pathology. None of the studies reported recurrence or reruptures. However, five patients (6.7%) did not return to their previous activity level.
Conclusion Patients can expect favorable outcomes with a potentially low complication rate. Nevertheless, the heterogeneity of the sample population, operative techniques, and outcome measures warrant further standardized studies.
Level of Evidence IV.
Surgical Management of Craniosynostosis—Between the Past and the Future: A Comprehensive Review of the Literature
Authors: Fouda Mohammed A 
Published: April 2023

AbstractCranial sutures are fibrous joints between the bones of the cranial vault, acting as centers of osteogenesis of the embryonic mesenchyme. Skull growth is a strictly regulated process, controlled by several genetic pathways. A minor perturbation of these pathways may lead to premature fusion of the cranial sutures. Craniosynostosis occurs as a result of the premature fusion of the cranial sutures. The incidence of craniosynostosis is approximately 1 in 2,500 live births. Syndromic craniosynostoses such as Apert, Crouzon, and Pfeiffer comprise 15% of patients, while nonsyndromic craniosynostosis represents 85% of all patients. By the late 1800s, Lannelongue (Paris, 1890) and Lane (San Francisco, 1892) attempted the first surgical intervention (strip craniectomy) for the management of craniosynostosis. The inadequacy of simple suturectomies and strip craniectomies in the management of craniosynostosis led to the innovation of more complex procedures such as frontoorbital advancement and posterior cranial vault distraction. However, these extensive surgical interventions are lengthy procedures and associated with more blood volume loss which requires blood transfusion. These limitations led to the modern era of minimally invasive endoscopic techniques. In this paper, we reviewed the body of the literature on the evolution of surgical management of craniosynostosis over the last century and the possible future directions.

Published: April 2023

Background Oral cavity cancers require definitive surgical resection as the primary treatment, but with advanced T stage, complete resection with pathologically negative margins might be difficult to achieve. Induction chemotherapy helps achieve the balance between resection and morbidity in locally advanced technically unresectable tumors. The aim of this study was to analyze the impact of surgery in locally advanced, technically unresectable oral cavity cancers after neoadjuvant chemotherapy (NACT).
Materials and Methods A retrospective analysis of patients with borderline resectable, locally advanced oral cavity cancers who were given NACT between February 2017 and December 2021 was conducted. Data regarding clinical and pathological characteristics, NACT, surgery, adjuvant therapy, and recurrences was analyzed.
Results Of the 69 patients in the study, 69.6% had tongue cancer, rest were gingivobuccal complex cancers. All tumors were resected based on the post-NACT tumor volume and clear margins were achieved in 42% of cases. About 85.4% of the tongue cancers required a lesser resection than anticipated, thereby following the concept of organ and functional preservation post-NACT as proposed by Licitra et al. About 30.4% had ypT0 and 17.4% had ypN0. Recurrence and survival rates noted in our study were comparable to those reported in literature. Lymph node density of more than or equal to 0.07 was found in all recurrent cases.
Conclusions Induction chemotherapy offers a chance of achieving adequate surgical resection while reducing morbidity and improving functional outcomes for patients with technically unresectable oral cavity cancers. Nodal disease may not respond to chemotherapy as well as the primary tumor. There is a need for comprehensive evaluation of prognostic factors, which could help identify the patients who will most benefit with NACT.
Spinal Epidural Collection following Lumbar Puncture in a Patient with Idiopathic Intracranial Hypertension

Published: April 2023

AbstractEpidural cerebrospinal fluid (CSF) collections after lumbar puncture are a rare and underdiagnosed entity in the pediatric population. Physicians should maintain vigilance about warning signs of severe progressive back pain extending beyond the puncture site and new neurological symptoms after lumbar puncture. Extensive symptomatic epidural collections, which may be dorsal and compromise the thecal sac, can be secondary to CSF leakage. Early diagnosis with spinal magnetic resonance imaging and prompt treatment is vital in reducing morbidity and mortality. These collections typically resolve with conservative management and no serious sequelae. We report a rare case of spinal epidural collection following a lumbar puncture in a patient with idiopathic intracranial hypertension that was successfully treated with a blood patch and surgical decompression in the setting of significant neurological deterioration.
Bacterial origin of a key innovation in the evolution of the vertebrate eye

Published: April 2023

The vertebrate eye was described by Charles Darwin as one of the greatest potential challenges to a theory of natural selection by stepwise evolutionary processes. While numerous evolutionary transitions that led to the vertebrate eye have been explained, some aspects appear to be vertebrate specific with no obvious metazoan precursor. One critical difference between vertebrate and invertebrate vision hinges on interphotoreceptor retinoid-binding protein (IRBP, also known as retinol-binding protein, RBP3), which enables the physical separation and specialization of cells in the vertebrate visual cycle by promoting retinoid shuttling between cell types. While IRBP has been functionally described, its evolutionary origin has remained elusive. Here, we show that IRBP arose via acquisition of novel genetic material from bacteria by interdomain horizontal gene transfer (iHGT). We demonstrate that a gene encoding a bacterial peptidase was acquired prior to the radiation of extant vertebrates >500 Mya and underwent subsequent domain duplication and neofunctionalization to give rise to vertebrate IRBP. Our phylogenomic analyses on >900 high-quality genomes across the tree of life provided the resolution to distinguish contamination in genome assemblies from true instances of horizontal acquisition of IRBP and led us to discover additional independent transfers of the same bacterial peptidase gene family into distinct eukaryotic lineages. Importantly, this work illustrates the evolutionary basis of a key transition that led to the vertebrate visual cycle and highlights the striking impact that acquisition of bacterial genes has had on vertebrate evolution.

ABSTRACTThere is conflicting evidence regarding the prevalence and magnitude of exercise‐induced muscle damage (EIMD) following low‐load resistance exercise with blood flow restriction (LL + BFR) that may be related to exercise protocols. The purpose of this investigation was to examine the effects of 75‐repetition (BFR‐75) (1 × 30, 3 × 15) and 4 sets to failure (BFR‐4x) protocols on indices of EIMD among untrained women. Thirteen women completed this investigation. One leg was randomly assigned to BFR‐75 and the other to BFR‐4x. Each leg performed isokinetic, unilateral, concentric‐eccentric, leg extension muscle actions at 30% of maximal strength. Indices of EIMD (muscle soreness, range of motion [ROM], limb circumference, pain pressure threshold [PPT], and maximal voluntary isometric contraction [MVIC]) were recorded before exercise, 0‐, 24‐, 48‐, 72‐, and 96‐hours post‐exercise. There were no changes for ROM, circumference, or PPT. Muscle soreness increased similarly in both conditions 0‐, 24‐, and 48‐hours post‐exercise and MVIC increased 24‐, 48‐, 72‐, and 96‐hours post‐exercise. These findings suggested BFR‐75 and BFR‐4x were not associated with EIMD and elicited similar physiological responses. The increases in muscle soreness may be due to metabolic stress associated with LL + BFR protocols apart from EIMD.
Controllability of shock waves in one-dimensional polariton condensates

Published: April 2023

Abstract
In one-dimensional incoherent pumped exciton–polariton condensates, we realize the generation and control of supersonic shock waves. By choosing a suitable initial input wave, we obtain the region of existence of various shock waves as a function of the phase of the initial wave, the coefficient of polariton interaction, the coefficient of the interaction between polariton and reservoir and the condensation rate and intensity of pumping. Using these results, we discuss the effect of different parameters on shock waves composed of two shock waves, and find that the gain and loss will result in a sloping platform between two waves. In addition, we also consider the effect of the non-adiabatic approximation and the diffusion coefficient of the reservoir on the profiles of the shock waves. We find that the non-adiabatic approximation will result in some small oscillations on the uniform background, and the platform between two waves becomes flat; however, the diffusion effect of the reservoir will clear these small oscillations and tilt the platform. Our results may pave the way to control shock waves in an incoherent pumped exciton–polariton system.

Published: April 2023

Abstract
In this paper we explore the formation of bars and present the bulge and bar properties and their correlations for a sample of lenticular barred (SB0) and lenticular unbarred (S0) galaxies in the central region of the Coma Cluster using HST/ACS data. In our sample, we identified bar features using the luminosity profile decomposition software GALFIT. We classified the bulges based on Sérsic index and Kormendy relation. We found that the average mass of the bulge in SB0 galaxies is 1.48 × 1010
M
☉ whereas the average mass of the bulge in S0 galaxies is 4.3 × 1010
M
☉. We observe that SB0 galaxies show lower bulge concentration, low mass and also smaller B/T values compared to S0 galaxies. Using the Kormendy relation, we found that among the lenticular barred galaxies, 82% have classical bulges and 18% have pseudo bulges. These classical bulges have low masses compared to the classical bulges of unbarred galaxies. S0, galaxies with massive classical bulges do not host bars. We also found that for all SB0s the bulge effective radius is less than the bar effective radius. SB0 galaxies with classical bulges suggest that the bar may have formed by mergers.

Abstract
The research of flare forecast based on the machine learning algorithm is an important content of space science. In order to improve the reliability of the data-driven model and weaken the impact of imbalanced data set on its forecast performance, we proposes a resampling method suitable for flare forecasting and a Particle Swarm Optimization (PSO)-based Support Vector Machine (SVM) regular term optimization method. Considering the problem of intra-class imbalance and inter-class imbalance in flare samples, we adopt the density clustering method combined with the Synthetic Minority Over-sampling Technique (SMOTE) oversampling method, and performs the interpolation operation based on Euclidean distance on the basis of analyzing the clustering space in the minority class. At the same time, for the problem that the objective function used for strong classification in SVM cannot adapt to the sample noise, In this research, on the basis of adding regularization parameters, the PSO algorithm is used to optimize the hyperparameters, which can maximize the performance of the classifier. Finally, through a comprehensive comparison test, it is proved that the method designed can be well applied to the flare forecast problem, and the effectiveness of the method is proved.
