IntroductionSleep-disordered breathing (SDB) can range from habitual snoring to severe obstructive sleep apnea (OSA). A common characteristic of SDB in children is mouth breathing, yet it is commonly overlooked and inconsistently diagnosed. The primary aim of this study is to construct a deep learning algorithm in order to automatically detect mouth breathing events in children from polysomnography (PSG) recordings.MethodsThe PSG of 20 subjects aged 10–13 years were used, 15 of which had reported snoring or presented high snoring and/or high OSA values by scoring conducted by a sleep technologist, including mouth breathing events. The separately measured mouth and nasal pressure signals from the PSG were fed through convolutional neural networks to identify mouth breathing events.ResultsThe finalized model presented 93.5% accuracy, 97.8% precision, 89% true positive rate, and 2% false positive rate when applied to the validation data that was set aside from the training data. The model's performance decreased when applied to a second validation data set, indicating a need for a larger training set.ConclusionThe results show the potential of deep neural networks in the analysis and classification of biological signals, and illustrates the usefulness of machine learning in sleep analysis.

IntroductionOptimal planning and minimally invasive surgical approach are essential to complete craniopharyngiomas (CP) resection with limited postoperative morbidity. Given the nature of craniopharyngioma recurrence, complete resection of the neoplasm is crucial. Since CP arise from the pituitary stalk and may grow anteriorly or laterally, some cases require an extended endonasal craniotomy. The extension of the craniotomy is crucial to expose the whole tumor and to make its dissection from the surrounding structures feasible. In order to guide the extension of the approach, the intraoperative use of ultrasound is helpful for the surgeons. The objective of this paper is to describe and to demonstrate the applicability of the utilization of intraoperative ultrasound (US) guidance for planning and confirmation of craniopharyngioma resection in EES.MethodThe authors selected one operative video of a sellar-suprassellar craniopharyngioma gross-totally resected by EES. The authors demonstrate the extended sellar craniotomy, the anatomic landmarks that guide bone drilling and dural opening, the aspect of the intraoperative real time US, tumor resection and dissection from the surrounding structures.ResultsThe solid component of the tumor was mostly isoechogenic in texture compared to the anterior pituitary gland, with several wide spread hyperechogenic images corresponding to calcifications and hypoechogenic vesicles corresponding to cysts inside the CF (“salt-and-pepper” pattern).DiscussionThe intraoperative endonasal US is a new surgical tool that allows for real-time active imaging for skull base procedures, such as sellar region tumors. Besides tumor evaluation, the intraoperative US helps the neurosurgeon to determine the size of craniotomy, to anticipate the relation between the tumor and vascular structures and to guide the best strategy for gross-total resection of the tumor.ConclusionThe EES allows a straight access to the craniopharyngiomas located in the sellar region or that grow anteriorly or superiorly. This approach allows the surgeon to dissect the tumor with minimal manipulation of the surrounding structures, when compared to craniotomy approaches. In order to accomplish that, the use of intraoperative endonasal ultrasound helps the neurosurgeon to perform the most suitable strategy, optimizing the rate of success.

Published: February 2023

BackgroundSitus inversus totalis (SIT) is a congenital condition wherein organs in abdominal or thoracic cavity are mirrored from their normal positions. Abdominal cocoon, is a rare disease of unknown aetiology that is characterised by total or partial small intestine encapsulation by a compact fibrocollagenous membrane. Aside from having two extremely rare conditions (SIT and Abdominal cocoon), our patient developed renal cell carcinoma (RCC), which makes this case even more uncommon.Case PresentationWe report the case of a 64-year-old man who was admitted to our hospital with an extremely rare case of localized RCC in the left kidney complicated with SIT and abdominal cocoon. Computer tomography urography (CTU) and angiography (CTA) showed that the patient was confirmed as having SIT, for the space-occupying lesion in the left kidney, clear cell RCC (ccRCC) was considered, the lesion in the right kidney was probably cystic. We diagnosed our patient as having a cT1aN0M0 left RCC, and the RENAL score was 7x. With partial nephrectomy (PN) being the preferred treatment approach, robot-assisted laparoscopic partial nephrectomy (RALPN) was performed after obtaining informed consent. After insertion of the laparoscope, adhesions were observed between the entire colon and the anterior abdominal wall. Then, abdominal cocoon was diagnosed. The surgery was uneventful, and the tumour was resected successfully while preserving the tumour capsule. No intestinal injury or any other complication occurred in the intraoperative or postoperative, and the patient recovered well after the operation.ConclusionPN is an extremely challenging procedure in patients with SIT and abdominal cocoon. The da Vinci Xi surgical system and thorough preoperative assessment allowed the surgeon to overcome stereotyping, visual inversion, and successfully perform PN in a patient with SIT and abdominal cocoon without increasing the risk of complications and preserving as much renal function as possible. Considering the satisfactory outcomes, this report may hopefully provide a practical reference for the treatment of RCC in patients with other special conditions.

AimThe aim of this study was to investigate the effect of the largest metastatic lymph node (MLN) size on postoperative outcomes of patients with stage II-III gastric cancer (GC).MethodsA total of 163 patients with stage II/III GC who underwent curative surgery were included in this single-center retrospective study. The lymph nodes were counted, each lymph node was analyzed for metastatic involvement by histopathological examination, and the diameter of the largest metastatic lymph node was recorded. The severity of postoperative complications was assessed by Clavien–Dindo classification system. Two groups of 163 patients were defined according to ROC analysis with cut-off value of histopathologically maximum MLN diameter. A comparative analysis of demographic and clinicopathological characteristics of the patients and their postoperative outcomes were performed.ResultsThe median hospital stay was significantly longer in patients with major complications compared to patients without major complications [18 days (IQR: 13–24) vs. 8 days (IQR: 7–11); (p &lt; 0.001)]. The median MLN size was significantly larger in deceased patients compared to survived [1.3 cm (IQR: 0.8–1.6) vs. 0.9 cm (IQR: 0.6–1.2), respectively; (p &lt; 0.001)]. The cut-off value of MLN size predicting mortality was found as 1.05 cm. MLN size ≥1.05 cm had nearly 3.5 times more negative impact on survival.ConclusionsThe largest metastatic lymph node size had a significant association with survival outcomes. Particularly, MLN size over 1.05 cm was associated with worse survival outcomes. However, the largest MLN was not shown to have any effect on major complications. Further prospective and large-scale studies are required to draw more precise conclusions.

AbstractHumans read the minds of others to predict their actions and efficiently navigate social environments, a capacity called mentalizing. Accumulating evidence suggests that the cerebellum, especially Crus 1 and 2, and lobule IX are involved in identifying the sequence of others’ actions. In the current study, we investigated the neural correlates that underly predicting others’ intentions and how this plays out in the sequence of their actions. We developed a novel intention prediction task, which required participants to put protagonists’ behaviors in the correct chronological order based on the protagonists’ honest or deceitful intentions (i.e., inducing true or false beliefs in others). We found robust activation of cerebellar lobule IX and key mentalizing areas in the neocortex when participants ordered protagonists’ intentional behaviors compared with not ordering behaviors or to ordering object scenarios. Unlike a previous task that involved prediction based on personality traits that recruited cerebellar Crus 1 and 2, and lobule IX (Haihambo et al., 2021), the present task recruited only the cerebellar lobule IX. These results suggest that cerebellar lobule IX may be generally involved in social action sequence prediction, and that different areas of the cerebellum are specialized for distinct mentalizing functions.

Published: February 2023

La presente revisión narrativa tiene como objeto describir el rol de los micronutrientes y su relación con la respuesta inmunitaria en el individuo adulto con la finalidad de caracterizar su sitio de acción, función y repercusiones en la eficacia de la misma. Los micronutrientes son considerados elementos con una proporcionalidad mínima en los requerimientos nutricionales diarios, sin embargo su significancia va más allá de su valor numérico puesto que cumple un papel protagónico como mediador metabólico, bioquímico e inmunitario. El mantenimiento y el desempeño de la función inmunitaria natural y celular se ha correlacionado con elementos como : vitamina C con acciones de efecto antioxidante, vitamina D migración celular y neutrofílica, Zinc expresión de receptores linfocitarios para una respuesta efectiva celular, sulforafano acción proinflamatoria, quercetina inducción de enzimas antioxidantes de fase II, agente antiviral mediante inhibición de peroxidación lipídica y agregación plaquetaria. Resulta pertinente proporcionar niveles óptimos de los oligoelementos mediante la dieta balanceada y diversa y evitar caer en estados carenciales que merman la eficacia del sistema inmune .

Abstract
We report the discovery of two companion sources to a strongly lensed galaxy SPT0418-47 (“ring”) at redshift 4.225, targeted by the JWST Early Release Science program. We confirm that these sources are at a similar redshift to the ring based on Hα detected in the NIRSpec spectrum and [C ii] λ158 μm line from the Atacama Large Millimeter/submillimeter Array (ALMA). Using multiple spectral lines detected in JWST/NIRSpec, the rest-frame optical to infrared images from NIRCam and MIRI and far-infrared dust continuum detected by ALMA, we argue that the newly discovered sources are actually lensed images of the same companion galaxy SPT0418-SE, hereafter referred to “SE,” located within 5 kpc in the source plane of the ring. The star formation rate derived using [C ii] and the dust continuum puts a lower limit of 17 M
☉ yr−1, while the SFRHα
is estimated to be >2 times lower, thereby confirming that SE is a dust-obscured star-forming galaxy. Analysis using optical strong line diagnostics suggests that SE has near-solar elemental abundance, while the ring appears to have supersolar metallicity O/H and N/O. We attempt to reconcile the high metallicity in this system by invoking early onset of star formation with continuous high star-forming efficiency or by suggesting that optical strong line diagnostics need revision at high redshift. We suggest that SPT0418-47 resides in a massive dark-matter halo with yet-to-be-discovered neighbors. This work highlights the importance of joint analysis of JWST and ALMA data for a deep and complete picture of the early universe.
Early Stages of Galilean Moon Formation in a Water-depleted Environment

Published: February 2023

Abstract
A key feature of the Galilean satellite system is its monotonic decrease in bulk density with growing distance from Jupiter, indicating an ice mass fraction that is zero in the innermost moon Io and about half in the outer moons Ganymede and Callisto. Jupiter-formation models, and perhaps the Juno spacecraft water measurements, are consistent with the possibility that the Jovian system may have formed, at least partly, from ice-poor material. And yet, models of the formation of the Galilean satellites usually assume abundant water ice in the system. Here, we investigate the possibility that the Jovian circumplanetary disk was populated with ice-depleted chondritic minerals, including phyllosilicates. We show that the dehydration of such particles and the outward diffusion of the released water vapor allow condensation of significant amounts of ice in the formation region of Ganymede and Callisto in the Jovian circumplanetary disk. Our model predicts that Europa, Ganymede, and Callisto should have accreted little, if any, volatiles other than water ice, in contrast to the comet-like composition of Saturn’s moon Enceladus. This mechanism allows for the presence of ice-rich moons in water-depleted formation environments around exoplanets as well.
Hypervelocity Stars Track Back to the Galactic Center in Gaia DR3

Published: February 2023

Abstract
Based on the proper motions and radial velocities from Gaia Data Release 3, we identify two hypervelocity stars (HVSs) that may originate from the Galactic center (GC). We select the candidates by first filtering for all Gaia stars with Galactocentric radial velocities >500 km s−1. We also require the candidates cross the Galactic midplane only once at 80% confidence, as determined by backwards orbit integration in several models of the Galactic potential, given the uncertainties in the Gaia measurables. The final two HVS candidates are the only such stars in our sample whose backwards-integrated trajectories pass within 1 kpc of the GC, suggesting a potential GC origin. We discuss possible ejection scenarios for these HVSs, in particular, by finding that ejection via the Hills mechanism is unlikely unless the HVS trajectories were significantly altered by local or large-scale perturbations to the assumed Galactic potential, e.g., the Large Magellanic Cloud. Interestingly, one of the HVSs ejects in a direction that is curiously aligned with the clockwise stellar disk around Sgr A*, suggesting a possible connection. We also discuss that the two stars may be ejected by other mechanisms.
Les certificats d’économie d’énergie entre économie et politique

Published: February 2023

Les certificats d’économie d’énergie (CEE) encouragent la rénovation des bâtiments et le remplacement de vieux équipements en obligeant les fournisseurs de gaz naturel, d’électricité et de fioul à réduire leurs livraisons. L’analyse microéconomique permet de relier le marché des certificats au marché des travaux d’économies d’énergie et à celui de l’énergie. Le handicap informationnel des ménages pour évaluer le lien entre travaux et consommation d’énergie et l’appartenance des travaux à la catégorie des « biens de confiance » expliquent la faible efficacité quantitative et financière du dispositif. Nous expliquons aussi pourquoi les CEE gardent les faveurs des pouvoirs publics malgré leurs mauvaises performances en mettant en avant leur appartenance à la panoplie des micropolitiques non punitives, non fiscales, décentralisées et créatrices d’emplois locaux.

La capitalisation du prix des vins dans le prix des vignes en Côte-d’Or
Authors: Ay Jean-Sauveur , Diallo Abdoul , Pham Hai-Vu 
Published: February 2023

Le prix des vignes sous appellation d’origine contrôlée (AOC) a fortement augmenté ces dernières décennies, au point de questionner sa connexion aux revenus issus de la vente de vin. Dans cet article, nous utilisons le modèle de capitalisation pour confronter les prix observés lors des mutations foncières aux revenus d’exploitation estimés à partir du prix des vins. Nous obtenons que les prix des vignes entre AOC augmentent plus fortement que les différences de revenus associés. Nous montrons que cette déconnexion peut s’expliquer par des effets de gamme pour l’acheteur, issus de la diversification de l’offre permise par l’achat de vigne. Par contre, la dynamique des prix n’est pas significativement différente de celle prédite par le modèle de capitalisation, ce qui va à l’encontre d’une potentielle spéculation foncière.

Sortir de la lutte armée : dissonances cognitives et contradictions normatives. Le cas du PKK
Authors: Guibet Lafaye Caroline 
Published: February 2023

Alors que l’engagement dans les organisations terroristes et les mouvements sociaux a suscité une littérature pléthorique, peu de travaux existent sur la sortie de ces deux types de collectifs. Pour saisir la pluralité des facteurs intervenant dans ces processus, nous nous sommes appuyés sur une enquête de sociologie empirique menée auprès de 64 militant.e.s du Partiya Karkerên Kurdistan (PKK). En effet, ce parti a connu une importante vague de départs de la guérilla au début des années 2000. L’étude microsociologique des trajectoires de désengagement conduit à nuancer le rôle de l’idéologie mis en avant par l’analyse méso-sociologique comme facteur explicatif des sorties de la violence. Elle est en outre utile pour mettre en évidence l’effet de la synergie entre facteurs méso (tels que les dysfonctionnements organisationnels) et facteurs micro (raisons personnelles, dissonances cognitives induites par l’identification de contradiction avec les valeurs qui motivent l’enrôlement et la réalité de la vie au sein de la guérilla) pour justifier la sortie de la clandestinité.
