Abstract
We measure the molecular gas environment near recent (<100 yr old) supernovae (SNe) using ∼1″ or ≤150 pc resolution CO (2–1) maps from the PHANGS–Atacama Large Millimeter/submillimeter Array (ALMA) survey of nearby star-forming galaxies. This is arguably the first such study to approach the scales of individual massive molecular clouds (M
mol ≳ 105.3
M
⊙). Using the Open Supernova Catalog, we identify 63 SNe within the PHANGS–ALMA footprint. We detect CO (2–1) emission near ∼60% of the sample at 150 pc resolution, compared to ∼35% of map pixels with CO (2–1) emission, and up to ∼95% of the SNe at 1 kpc resolution, compared to ∼80% of map pixels with CO (2–1) emission. We expect the ∼60% of SNe within the same 150 pc beam, as a giant molecular cloud will likely interact with these clouds in the future, consistent with the observation of widespread SN–molecular gas interaction in the Milky Way, while the other ∼40% of SNe without strong CO (2–1) detections will deposit their energy in the diffuse interstellar medium, perhaps helping drive large-scale turbulence or galactic outflows. Broken down by type, we detect CO (2–1) emission at the sites of ∼85% of our 9 stripped-envelope SNe (SESNe), ∼40% of our 34 Type II SNe, and ∼35% of our 13 Type Ia SNe, indicating that SESNe are most closely associated with the brightest CO (2–1) emitting regions in our sample. Our results confirm that SN explosions are not restricted to only the densest gas, and instead exert feedback across a wide range of molecular gas densities.
Molecular Gas Properties in Young Stellar Clusters with a Suppressed Star Cluster Wind

Published: February 2023

Abstract
In compact and dense star-forming clouds a global star cluster wind could be suppressed. In this case stellar feedback is unable to expel the leftover gas from the cluster. Young massive stars remain embedded in a dense residual gas and stir it by moving in the gravitational well of the system. Here we present a self-consistent model for the molecular gas distribution in such young, enshrouded stellar clusters. It is assumed that the cloud collapse terminates and the star formation ceases when a balance between the turbulent pressure and gravity and between the turbulent energy dissipation and regeneration rates is established. These conditions result in an equation that determines the residual gas density distribution that, in turn, allows one to determine the other characteristics of the leftover gas and the star formation efficiency. It is shown that our model predictions are in good agreement with several observationally determined properties of cloud D1 in the nearby dwarf spheroidal galaxy NGC 5253 and its embedded cluster.

Abstract
We present new 0.3–21 μm photometry of SN 2021aefx in the spiral galaxy NGC 1566 at +357 days after B-band maximum, including the first detection of any Type Ia supernova (SN Ia) at >15 μm. These observations follow earlier JWST observations of SN 2021aefx at +255 days after the time of maximum brightness, allowing us to probe the temporal evolution of the emission properties. We measure the fraction of flux emerging at different wavelengths and its temporal evolution. Additionally, the integrated 0.3–14 μm decay rate of Δm
0.3–14 = 1.35 ± 0.05 mag/100 days is higher than the decline rate from the radioactive decay of 56Co of ∼1.2 mag/100 days. The most plausible explanation for this discrepancy is that flux is shifting to >14 μm, and future JWST observations of SNe Ia will be able to directly test this hypothesis. However, models predicting nonradiative energy loss cannot be excluded with the present data.
The Far-ultraviolet Variability of the Early A-type Star HD 1280 (θ And)
Authors: Monier Richard 
Published: February 2023

Abstract
The analysis of two spectra of the early A-type star HD 1280, recorded by the SWP camera on board the International Ultraviolet Explorer, reveals large variations of the far-ultraviolet flux shortwards of 1850 Å. The amplitude of these variations increases toward shorter wavelengths. In contrast, the mid-ultraviolet flux from 2200 up to 3000 Å is constant in the available spectra collected with the LWP camera. These variations could be due to large horizontal chemical or thermal gradients over the stellar surface, or stellar pulsation, or the presence of a companion.
The Effect of Multiple Low-mass Flybys Can Preserve the Orbit of Neptune-like Objects in Slightly Perturbed Orbits in Star Formation Clusters
Authors: Jiménez-Torres Juan J. 
Published: February 2023

Abstract
The objective of this work is focused on solving the problem in the regular theory where the strong effects of single impacts on proplanetary particles in the early stages of the Solar system can noticeably perturb the orbit of inner planets such as Neptune. As a first-approach solution, I propose that multiple low-mass flybys can produce the observed orbit of a Neptune-like particle. I calculated the effects of four subsequent flybys to know the difference between their effects and the effect of a massive encounter. The effects of multiple low-mass impacts deliver lower eccentricities and inclinations of the planetary particle compared to the result produced by the single encounter.

Published: February 2023

ObjectiveMedial opening wedge high tibial osteotomy (HTO) aims to improve symptoms for patients with knee osteoarthritis (OA) and varus alignment, yet the likelihood of achieving a minimum clinical threshold of response and the factors predictive of response are unclear. We evaluated the proportion of patients meeting responder criteria based on the Outcome Measures in Rheumatology–Osteoarthritis Research Society International consensus 2 years after medial opening wedge HTO and investigated predictors of response.MethodsPatients in a prospective cohort with symptomatic knee OA and varus alignment completed the Knee Injury and Osteoarthritis Outcome Score questionnaire < 3 months before and 2 years after HTO. For our primary analysis, we calculated the proportion of responders with ≥ 20% relative improvement and an absolute change of ≥ 10 points in pain and function from baseline. We performed logistic regression to evaluate the association of predictors with response and completed sex-disaggregated analyses.ResultsAt a mean of 20.3 (SD 6.2) months post-HTO, 406 patients (78%) met the responder criteria. Older age, higher BMI, and larger postoperative mechanical axis angles (ie, slight valgus) were associated with increased odds of achieving responder criteria, although odds ratios were small. When stratified by sex, 316/405 male patients (78%) and 90/118 female patients (76%) met the responder criteria.ConclusionBased on responder criteria for knee OA, 78% of patients undergoing medial opening wedge HTO were responders at 2 years postsurgery. Although patients who are younger, male, and nonobese are viewed as appropriate candidates for HTO, patients who are female, are older, and have a high BMI also achieve sizable improvements in pain and function.
Qui sont les conducteurs infractionnistes qui participent à au moins trois stages de sensibilisation à la sécurité routière en cinq ans ? Sont-ils différents de ceux qui y participent pour la première fois ?
Authors: Karras Marion , Delhomme Patricia , Csillik Antonia 
Published: February 2023

L’objectif de cette enquête est de comparer les dimensions comportementales et psychologiques des conducteurs participant à trois stages de sensibilisation à la sécurité routière en cinq ans (dits réitérants), et de ceux qui participent pour la première fois (dits primo-stagiaires), et d’étudier les ressources et vulnérabilités psychologiques qui prédisent leurs comportements routiers. Au cours de 110 stages, 241 réitérants et 560 primo-stagiaires ont complété un questionnaire « papier-crayon ». Comparés aux primo-stagiaires, les réitérants déclarent s’engager plus souvent dans des infractions et des activités distrayantes non liées à la conduite, et être davantage impliqués dans des accidents de la route. Disposition à l’attention consciente et expression agressive de la colère au volant prédisent les comportements des réitérants et des primo-stagiaires.
D’un corps mollusque à un véhicule turbo ! Comment l’inclusion scolaire est facilitée par l’entremise des objets autistiques et du double
Authors: Toussaint Hélène , Grollier Michel 
Published: February 2023

Cet article s’intéresse particulièrement aux conditions facilitatrices que permet la prise en compte des objets autistiques et du double dans le processus inclusif des enfants autistes à l’école. Cet abord s’oriente particulièrement à partir des théories psychanalytiques lacaniennes touchant le traitement de la jouissance dans l’autisme grâce à la construction de ce que nous nommons « un bord ». Cette notion va être ici dépliée dans toute sa dimension clinique et opérationnelle avec l’illustration d’un cas clinique. Il s’agit du cas de Lilian, jeune garçon autiste de quatorze ans accompagné par un Service d’éducation et de soins spécialisés à domicile (SESSAD) depuis sept ans. Les données recueillies sont issues des séances éducatives et thérapeutiques avec Lilian, ainsi que du travail en lien avec ses parents et les équipes pédagogiques.
La Convention citoyenne pour le climat a-t-elle travaillé comme une assemblée parlementaire ?
Authors: Buge Éric 
Published: February 2023

L’article compare le fonctionnement de la Convention citoyenne pour le climat française (CCC) avec celui des missions d’information de l’Assemblée nationale. D’une part, il montre que si les deux structures reposent sur une forme de division du travail entre leurs membres, cette dernière repose sur des logiques différentes : affiliation partisane dans le cas de l’Assemblée et création d’une identité collective pour la CCC. D’autre part, si l’Assemblée distingue nettement les rôles des député·es, des fonctionnaires et des expert·es auditionné·es, la Convention a fonctionné comme un « collectif hybride » réunissant citoyen·nes, Comité de gouvernance, expert·es, etc. Sur le fondement de cette comparaison, l’article se conclut par quelques suggestions de design institutionnel pour les conventions à venir.

Tomber en syncope, telle est l’invitation de l’ouvrage Vertige de l’art. Syncopes et extases (xvie-xxie siècles). Ces états de vacatio propices à la création artistique à la Renaissance perdurent et entraînent les auteures à mettre en regard des œuvres modernes et contemporaines. Une syncope insaisissable et cependant présente dans le domaine scientifique, la littérature, la philosophie et la musique. Le concept de syncope-extase permet de déconstruire les perceptions de faiblesse ou de non-action apparentes et d’affirmer une échappée paradoxale, un contre-pouvoir.Hiatus, faille ou encore disjonction que l’artiste des différentes époques de l’art provoque et dont il s’agit d’interpréter la portée sociale et anthropologique. L’ouvrage donne ainsi à voir ou à éprouver ce moment syncopal, un hors-temps de l’histoire.

Abstract
The swede midge, Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae), is invasive to North America, where it was first reported in Ontario, Canada. It is now established in eastern Canada and from eastern Minnesota in the Midwest to the northeastern seaboard of the United States of America. Swede midge is a serious pest of brassicaceous plants, including vegetable and oilseed crops. To ensure its early detection in the Northern Great Plains, a monitoring programme was established using pheromone traps located primarily along the edges of canola fields from North Dakota, United States of America, northwest to the Peace River region, in Alberta and British Columbia, Canada. In North Dakota, 117 trap sites were monitored between 2015 and 2021. In western Canada, monitoring occurred on a small scale from 2006 to 2011, and 521 trap sites were monitored from 2013 to 2021. Swede midge was not detected in canola grown in the Northern Great Plains between 2006 and 2021. Partners in North Dakota and western Canada intend to maintain the monitoring programme to support early detection of swede midge if it does continue to disperse northwestwards. The monitoring programme contributes to outreach activities and fosters farmer and agronomist participation in pest management (i.e., community science) in the Northern Great Plains.

Background: The etiologies for ambiguous genitalia with palpable gonads include gonadal dysgenesis, congenital adrenal hyperplasia, androgen biosynthetic defects or androgen insensitivity. Klinefelter syndrome (1 in 500-1000 live male births) classically presents with hypergonadotropichypogonadism, infertility and neurocognitive deficits in adult men, and less frequently as isolated hypospadias and micropenis in infants. Klinefelter syndrome rarely can present with ambiguous genitalia. We detail a child with Klinefelter syndrome and associated androgen insensitivity presenting with genital ambiguity.

Case Details: 3 year 5 months old child (DOB: 6/5/19), reared as male, presented with complaints of ambiguous genitalia and small-sized penis since birth. He was passing urine from a normally located urethralopening. Although gonads were noticed in the scrotum since birth, there was bifid scrotum. There was no history of hypoglycemia, salt-wasting crises or hyperpigmentation. Child was born out of non-consanguineous marriage, by cesarean delivery, at term, with a birth weight of 2.6 kg. Child had attained developmental milestones appropriate for age. On examination, Ht:92 cm (-1.96 Z), Wt:13kg (-1.33 Z), BP: 85/54mmhg (SBP: 50th centile, DBP: 90th centile), MPH:162.5 cm, US:LS:0.7, Arm Span: 89 cm.
On examination, he had bilateral symmetric external genitalia with palpable gonads in the labio-scrotal folds. The labioscrotal folds were non-fused, but rugosity and pigmentation were present. Phallic length was 1.8 cm with a single urethral opening at the tip of phallus. EMS score was 6 and AG ratio was 0.5. Evaluation revealed Na:138, K:4.3, Cortisol:13.5 mcg/dl, LH: 0.862 mIU/ml, FSH:2.4 mIU/ml, Testosterone: 507 ng/dl. Post-hCG stimulation Testosterone/Dihydrotestosterone ratio was 12.43, while Testosterone/Androstenedione ratio was 22.96. Karyotype was 47,XXY. Genetic analysis revealed a pathogenic variant in the androgen receptor c.2495G>A (p.Arg832Gln), suggestive of androgen insensitivitysyndrome.

Discussion: There have been isolated case reports of genital ambiguity in Klinefelter syndrome with associated AIS. The mechanisms suggested to explain genital ambiguity in Klinefelter syndrome include parental origin of the X chromosome, skewed inactivation of the X chromosome, CAG repeat polymorphism, double dosage of DAX-1 gene and androgen insensitivity. Although rare, it remains paramount to recognize Klinefelter syndrome as a cause of genital ambiguity. Genotypic-phenotypic discordance in Klinefelter syndrome should especially alert the clinician to look for associated androgen insensitivity as one of the mechanisms.
Gastrointestinal Bezoars in Paediatrics
Authors: Elghazeery Mohamed Ahmed , Hassan Alhassan Mohamed 
Published: February 2023

Introduction:Bezoars are indigestible lumps which are usually found in stomach. Types of bezoar include phytobezoar, trichobezoar, lithobezoar, pharmacobezoar, plasticobezoar, lactobezoar and metal bezoar. Trichobezoars mostly affect females in 20s and 30s with a rarity in paediatrics. Unexplained complaints with a palpable mass are commonly found in these patients. Treatment involves retrieval of mass with searching for others.Purpose:The purpose of this study was to present data and surgical management of cases with trichobezoars.Materials and Methods:We documented a retrospective review of trichobezoars done in our hospital between 2016 and 2022. All demographic data collected included gender and age of cases, composition and extent of bezoar, clinical presentation, imaging modalities, endoscopic trial, surgical approach and outcome.Results:Five cases of gastrointestinal tract (GIT) trichobezoars underwent surgery. All cases were females between (13 and 16 years). Trichobezoars were three gastric, one ileal and one of combined gastric and colonic. Complaints were abdominal pain, vomiting, weight loss and halitosis. Three cases had a palpable abdominal mass. Different radiological modalities were performed. Endoscopic retrieval was tried in one patient and the laparoscopic approach in another one, but the first route failed. Laparotomy followed by gastrotomy, enterotomy and colotomy was done without complications.Conclusions:Trichobezoars should be suspected in any child with unexplained abdominal complaints or with a palpable abdominal mass, especially in girls. Imaging can be done in different modalities for diagnosis. Endoscopic retrieval could be tried; however, its failure is common, necessitating laparotomy, which has an excellent outcome.
Atypia of Undetermined Significance/Follicular Lesion of Undetermined Significance (Bethesda Category - III) in Thyroid Cytology
Authors: Das Prateek , Patnayak Rashmi , Bhola Rajesh , Jena Amitabh 
Published: February 2023

Introduction:
Fine-needle aspiration (FNA) cytology is a reliable method to diagnose thyroid lesions. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) is universally followed for thyroid cytology reporting. Out of the six categories described, Category III, atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) is the most heterogeneous one.

Materials and Methods:
In this study conducted in a tertiary health care center in Eastern India over 2 ½-year period, 868 thyroid FNAs were performed and the cytology smears were interpreted using the TBSRTC. There were 32 FNAs in Category III. Histopathology report was available in nine cases.

Results:
The risk of malignancy (ROM) considering noninvasive follicular thyroid carcinoma with papillary nuclear features (NIFTP) as benign was 9.3% and by considering NIFTP as malignant was 21.8%.

Conclusion:
The ROM for AUS/FLUS in our study was within the revised ROM criteria. In Category III, surgery is preferable in nodules which harbor suspicious features either clinically or according to ultrasound findings.

ABSTRACT

Background:
Treatment for carcinoma larynx is dependent on the T-category, with T4a disease (major thyroid cartilage involvement and extra-laryngeal extension) requiring radical surgery while lesser stages are treated with voice conserving treatments including radiation or chemoradiation. Pre-treatment computerized tomography (CT) scan is routinely used to categorize the T-category; however, studies have reported variable accuracy.

Objective:
We aimed to ascertain the accuracy of the preoperative CT scan in determining major thyroid cartilage involvement and T-category of the tumor when compared to the postoperative histopathology report.

Materials and Methods:
This retrospective observational study was conducted between January 01, 2017, and May 31, 2021, in the Department of Radiodiagnosis at the Homi Bhabha Cancer Hospital, Sangrur, Punjab (India). We analyzed the data of 30 patients with histologically proven squamous cell carcinoma of the larynx, who had undergone preoperative CT scans followed by total laryngectomy. The diagnostic accuracy of the T-category based on the preoperative CT, including major thyroid cartilage involvement, extra-laryngeal extension along with other laryngeal subsites was compared to the postoperative histopathology report.

Results:
CT scan was highly precise in determining the preoperative T-category with an accuracy of 90%. Detection of erosion of the outer cortex of the thyroid cartilage had a sensitivity of 94.4% (95% CI, 74.2-99) for major thyroid cartilage involvement. When erosion of the outer cortex of the thyroid cartilage was combined with the soft tissue on both sides of the thyroid cartilage, the CT scan yielded an accuracy of 100% (95% CI, 88.65-100). CT showed a sensitivity of 92.9% (95% CI, 68.5-98.7) and a specificity of 87.5% (95% CI, 63.9-96.5) for extra-laryngeal extension.

Conclusion:
CT scan is an accurate and reliable preoperative investigation for diagnosing major thyroid cartilage involvement and T-category staging in patients with carcinoma larynx.
