Abstract
During the Zwicky Transient Facility (ZTF) Phase I operations, 78 hydrogen-poor superluminous supernovae (SLSNe-I) were discovered in less than 3 yr, constituting the largest sample from a single survey. This paper (Paper I) presents the data, including the optical/UV light curves and classification spectra, while Paper II in this series will focus on the detailed analysis of the light curves and modeling. Our photometry is primarily taken by ZTF in the g, r, and i bands, and with additional data from other ground-based facilities and Swift. The events of our sample cover a redshift range of z = 0.06 − 0.67, with a median and 1σ error (16% and 84% percentiles) of

mag. The light curves evolve slowly with a mean rest-frame rise time of t
rise = 41.9 ± 17.8 days. The luminosity and timescale distributions suggest that low-luminosity SLSNe-I with a peak luminosity ∼−20 mag or extremely fast-rising events (<10 days) exist, but are rare. We confirm previous findings that slowly rising SLSNe-I also tend to fade slowly. The rest-frame color and temperature evolution show large scatters, suggesting that the SLSN-I population may have diverse spectral energy distributions. The peak rest-frame color shows a moderate correlation with the peak absolute magnitude, i.e., brighter SLSNe-I tend to have bluer colors. With optical and UV photometry, we construct the bolometric luminosity and derive a bolometric correction relation that is generally applicable for converting g, r-band photometry to the bolometric luminosity for SLSNe-I.
Early Insights for Atmospheric Retrievals of Exoplanets Using JWST Transit Spectroscopy

Abstract
We have entered the era of the James Webb Space Telescope (JWST). We use the first JWST transmission spectrum of the hot Saturn-mass exoplanet, WASP-39 b, obtained with the NIRSpec instrument in the 3–5 μm range to investigate (a) what atmospheric constraints are possible with JWST-quality data in this spectral range, (b) requirements for atmospheric models used in retrievals, (c) effect of differences between data reduction pipelines on retrieved atmospheric properties, and (d) complementarity between JWST data in the 3–5 μm range and Hubble Space Telescope (HST) observations at shorter wavelengths. JWST spectra in the 3–5 μm range provide a promising avenue for chemical detections while encompassing a window in cloud opacity for several prominent aerosols. We confirm recent inferences of CO2, SO2, H2O, and CO in WASP-39 b; report tentative evidence for H2S; and retrieve elemental abundances consistent with Saturn’s metallicity. We retrieve molecular abundances with ∼0.3–0.6 dex precision with this relatively limited spectral range. When considering the 3–5 μm data alone, reported differences in spectra with different reduction pipelines can affect abundance estimates by up to ∼1 dex and the detectability of less prominent species. Complementing with data at shorter wavelengths, e.g., with other JWST instruments or HST WFC3 (∼0.8–1.7 μm), can significantly improve the accuracy and precision of the abundance estimates. The high data quality enables constraints on aerosol properties, including their composition, modal size, and extent, motivating their consideration in retrievals. Our results highlight the promise of JWST exoplanet spectroscopy, while underscoring the importance of robust data reduction and atmospheric retrieval approaches in the JWST era.
Addictions et psychotraumatismes : aide au repérage
Authors: Camille Charles 
Published: January 2023

L’actualité médiatique bouleverse notre société : la dénonciation des abus sexuels subis dans l’enfance, les violences conjugales, l’errance des enfants placés, etc. Ces violences dénoncées libèrent la parole de ceux qui peuvent parler. Nous décrirons ici des modes d’usage spécifiques des patients qui utilisent les produits pour survivre à leurs traumatismes et donc les particularités cliniques des patients psychotraumatisés en addictologie. Ces symptômes du psychotraumatisme peuvent être déroutants pour les professionnels dans leurs accompagnements. Les résistances sont doubles : celle des spécialistes en addictologie dont la formation aux psychotraumatismes n’est pas établie, celle des patients qui n’ont pas identifié ou eu la possibilité de verbaliser la répercussion psychique de l’exposition à de tels événements. À partir d’une pratique de soins dans un service d’addictologie et d’une équipe mobile (EMTCA) dédiée à l’accompagnement des troubles des conduites alimentaires, nous proposons une aide au repérage des psychotraumatismes intriqués dans des conduites addictives.
L’analyse interprétative spécifique des œuvres plastiques en maternelle
Authors: Sanchez-Iborra Corinne 
Published: January 2023

L’objet de cet article sera de décrire et d’analyser de manière qualitative les interactions verbales, gestuelles, corporelles entre les élèves et leur enseignant de maternelle (cycle 1), lors de la fréquentation de certaines œuvres d’art plastiques. Nous nous interrogerons sur les effets en termes de compétences, d’attitudes chez de jeunes élèves, des dispositifs choisis en classe ou au musée. Ces moments montrent l’importance des corps des acteurs qui agissent plus ou moins librement. Peut-on repérer des usages récurrents ou des variations autour des œuvres reproduites et projetées ? Ces pratiques discursives semblent permettre une pratique interprétative progressive des élèves mais également des productions créatives. Quels sont les gestes professionnels de quatre professeurs des écoles stagiaires dans ces situations spécifiques ?
Ecrire l’histoire du la
Authors: Gribenski Fanny 
Published: January 2023

Alors qu’elle constitue une référence incontournable dans le monde musical occidental, la note la accordée à 440 hertz n’est devenue le ton de concert standard qu’à l’issue d’une conférence internationale organisée à Londres en 1939. Si l’histoire des variations du diapason a été étudiée dans la perspective d’une interprétation historiquement informée des répertoires musicaux, elle n’a jamais été envisagée comme un processus historique, social et politique, ce qui est surprenant au regard de la richesse des travaux consacrés à de semblables processus de standardisation (temps, poids et mesures) dans le domaine des études des sciences. Par cet article, je propose de remédier à cette lacune et de montrer, ce faisant, ce que les études des sciences apportent à la compréhension des pratiques musicales et, en retour, en quoi l’histoire du son constitue une source de renouvellement pour l’étude des processus de standardisation.
Vers une micropolitique des formats

Cet article croise des perspectives issues des études de sciences, des sciences de l’information et de la communication et des cultural studies. Il s’intéresse au dispositif Content ID édité par l’entreprise et site de publication de vidéos YouTube, qui permet d’identifier et de monétiser les morceaux de musique présents dans les vidéos. Il s’agit d’analyser la construction d’une innovation dans les marchés de la musique et de l’Internet. Ce dispositif s’inscrit dans la filiation d’enjeux stratégiques et de techniques liés à l’industrie musicale et à l’économie du Web, qui concernent l’arbitrage entre circulation des formes culturelles et leur contrôle comme œuvres et marchandises par le droit d’auteur : dans ce cadre, Content ID est présenté comme un compromis idéal. La mise en œuvre de cet idéal repose sur l’ancrage de l’œuvre musicale dans le son, sa modélisation informatique, et la naturalisation de ce modèle. Au-delà d’un équipement technique des règles de marché, il s’agit d’une semi-automatisation de jugements culturels et juridiques d’originalité. Content ID redéfinit ainsi discrètement les valeurs de la musique enregistrée, et la façon dont elles sont instituées.

Published: January 2023

La conférence de Seelisberg (1947) est la seconde conférence internationale réunissant Juifs et chrétiens dans l'après-guerre. L'article traite des difficultés de sa longue préparation et de son déroulement, mais aussi de ses retombées médiatiques, plutôt modestes dans un premier temps, avant que les « Dix Points » de Seelisberg s'imposent comme un texte majeur dans l'histoire des relations judéo-chrétiennes.

Published: January 2023

Background:
Gut microbiota plays an important role in the development of different diseases including colorectal cancer. The geography, lifestyle, and dietary habits of Indians are different from Western world, thus microbiome studies of Western population could not be extrapolated to their Indian counterparts.

Method:
Therefore, we have conducted a study on gut microbiota in Indian healthy subjects and patients of colon cancer using 16S ribosomal RNA Amplicon sequencing. Operational taxonomic units were calculated for different bacterial taxon including phylum, class, order, family, and genus level.

Results:
Observed results indicated a considerable difference in the bacterial diversity in both the groups. Phylum Firmicutes was significantly dominated in both the groups followed by Bacteroidetes, Actinobacteria, and Proteobacteria which clearly indicates the dominance of phylum Firmicutes in Indian population. Phylum Firmicutes and Actinobacteria were significantly abundant in the healthy group while phylum Bacteroidetes in the colon cancer group. Bacterial genera Megamonas, Megasphaera, Mitsuokella, and Streptococcus were significantly abundant in the healthy group and Veillonella, Prevotella, and Eubacterium in the colon cancer group. Bacterial genus Bradyrhizobium was present in the healthy group and Alistipes, Coprococcus, Dorea, and Rhodococcus were present in the colon cancer group but absent in the healthy group.

Conclusion:
There was a considerable difference in bacterial diversity in both the study groups indicating dysbiosis in the colon cancer group.

Published: January 2023

Objective:
To analyze data on socio-demographic and clinical characteristics of SARS-CoV-2 infected population whose samples were received from Medical Research Institute, Sri Lanka.

Methods:
Laboratory based retrospective study was done on patient samples which were tested positive for SARS-CoV-2 by National Reference Virology Laboratory at the Medical Research Institute, Sri Lanka, from November, 2020 to November, 2021. Data on socio-demographic characteristics and clinical presentation of 13 126 patients were examined.

Results:
The mean age of the study population was (36.0±7.2) years and the majority were men (64.0%). The highest number of positive cases were found in the 21-30 years-of-age group. Two distinct peaks were noted in the incidence of SARS-CoV-2 positive individuals. In addition, 42.5% of the positive samples tested positive (42.5%) were from Medical Officer of Health collection centres. Furthermore, 60.6% (7 951) of the infected subjects were asymptomatic whereas the remaining were symptomatic. The highest percentage of symptomatic patients were observed in the 91-100 years-of-age group while the highest asymptomatic subjects were found in the 31-40 years-of-age group. The percentage of asymptomatic children (65.3%) was significantly (P<0.05) higher than that of adults (43.4%).

Conclusions:
The findings of this study aid decision makers to focus on the vulnerable groups, and geographic and temporal distribution of patients in the public health strategies that aim at preventing the spread of the disease and reducinig its mortalities.

Published: January 2023

Objective:
To assess the knowledge of healthcare workers on the measles vaccine and its cold chain management.

Method:
An institutional-based cross-sectional study was conducted from February 1 to March 30, 2022 in Gondar City Administration public health institutions among 165 healthcare workers. Data were collected using a structured questionnaire. In addition, an on-spot observation checklist was used to assess the availability, status and management of the cold chain. A logistic regression model was used to assess the relationship between the outcome and predictor variables. Crude and adjusted odds ratios were calculated with 95% confidence intervals.

Results:
Overall, 87 (52.7%; 95% Cl 44.8%-60.5%) of the healthcare workers had unsatisfactory knowledge regarding the measles vaccine and its cold chain management. One hundred thirty-six (82.4%) healthcare workers correctly mentioned the recommended range of temperature (2-8 °C) for measles vaccine storage. Healthcare workers aged 18-29 years (P=0.001) and 30-44 years (P=0.014) were observed as determinants of unsatisfactory knowledge on the measles vaccine and its cold chain management. One hundred and five (63.6%) of the healthcare workers did not correctly mention the type of measles vaccine used in routine immunization. More than one-third (36.4%) of the healthcare workers perceived that the measles vaccine is not safe and could cause measles.

Conclusions:
More than half of the healthcare workers in the study area had unsatisfactory knowledge on the measles vaccine and its cold chain management. It is necessary to provide technical support and in-service training for healthcare workers to ensure optimal immunization effectiveness.

Authors: Gupta Ashutosh , Singh Inderpal , Gupta Meenu , Puri Isha 
Published: January 2023

Background:
Cancers in the head-and-neck region are the sixth most common cancers worldwide with an increasing incidence in developing countries.

Methods:
This study was carried out in the department of ENT and head-and-neck surgery in collaboration with the department of radiotherapy for a period of 1 year extending from May 01, 2014, to April 30, 2015. A total of 48 cases of metastatic secondary nodes were included in the study.

Results:
The male-to-female ratio in the present study was 4.33:1. Maximum number of patients were seen in the seventh decade. The youngest patient was a female 30 years old and the oldest was a male of 80 years. About 95.84% of primary tumors were squamous cell carcinomas and 40.47% of the patients of head-and-neck cancer with metastatic lymph nodes had well-differentiated squamous cell carcinomas. Majority of cases presented with N2 nodes, while N1 nodes were highest in cases of carcinomas larynx.

Conclusions:
Metastatic neck disease is a major problem in patients with head-and-neck cancer. The therapeutic goal includes not only known disease but also the elimination of possible subclinical disease. The judicious use of moderate doses of irradiation and modified surgical procedures should be used in specific clinical situations to significantly decrease neck recurrences while eliminating morbidity.

Published: January 2023

Purpose:
Recurrent nasopharyngeal carcinoma (NPC) after previous radiation therapy is a significant problem. This study was to determine the potential benefits from re-irradiation by fractionated stereotactic body radiotherapy (FSRT) on survival benefits and effects of severe late toxicities.

Materials and Methods:
Between 2009 and 2018, treatment outcomes were evaluated retrospectively in 26 patients with locally recurrent NPC treated using FSRT with CyberKnife. Five patients who had metastatic disease and one who had second recurrence were excluded from the study, and the remaining 20 patients were analyzed. The median age was 52 years (range, 28–80 years); re-treatment T stage was as follows: 6 (30%) – T2, 5 (25%) – T3, and 9 (45%) – T4. The median time from initial RT to recurrence was 22 months (range, 8–159 months). The median re-irradiation FSRT dose was 30 Gy in 5 fractions.

Results:
The median follow-up was 44 months; the overall survival (OS), local failure-free survival, and disease progression-free survival rates at 3 years were 89%, 73%, and 53%, respectively. All patients were evaluated for response after treatment: 9 (45%) had complete, 3 (15%) had partial, and 6 (30%) had no response. Univariate analysis demonstrated that higher cumulative total radiotherapy dose, gross tumor volume, and recurrent time interval were prognostic factors for local failure-free survival. The recurrent time interval was also an independent factor for progression-free survival and OS. The incidence of temporal lobe necrosis and trismus was 10% and 20%, respectively. One patient had Grade 5 toxicity to treatment-related bleeding.

Conclusion:
Tumor dose coverage is important for treating recurrent NPC, and treatment-related mortality was vascular in nature. FSRT is a promising treatment modality for recurrent NPC.
Evaluation of enzyme-linked immunosorbent assay plasma p16INK4a protein in squamous cell carcinoma in uterine cervix
Authors: Raju Kalyani , Raghuveer C. V. , Sheela S. R. , Natarajan Arvind , Jagadish T. V. , Sunil B. N. , Sharat B. 
Published: January 2023

Background:
Cervical cancer is one of the common cancers in females. The common method of screening is Pap test which has low sensitivity. Hence, better methods are explored with different biomarkers, of which estimation of P16 protein can be opted in early detection of cervical cancer.

Materials and Methods:
Seventy cases and seventy controls were considered for the study. Cases were invasive squamous cell carcinoma (SCC) of cervix confirmed by histopathology. Controls were healthy age-matched females. The blood sample of cases and controls was collected in K2 Ethylenediaminetetraacetic acid vacutainer, and the separated plasma was subjected to estimation of P16 protein by quantitative sandwich Enzyme-Linked ImmunoSorbent Assay method. The data were analyzed for the association between p16 protein in plasma in cases and controls.

Results:
The age among cases and controls ranged from 30 to 80 years. The P16 levels among cases ranged from 3.4 to 19.6 ng/ml with a mean of 7.24 ± 2.35 ng/ml. The plasma P16 level in controls ranged between 0.9 and 9.7 ng/ml with mean of 4.1 ± 2.22 ng/ml. At cutoff more than 4.8 ng/ml in cases, the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were 92.86%, 72.86%, 77.4%, 91.1%, and 82.86%, respectively. The specificity increased with increase in plasma p16 levels. The P16 levels were maximum in stage IV disease.

Conclusion:
This was a pilot study to detect the plasma p16INK4a levels in SCC of cervix. The levels of plasma p16 protein between 3.9 and 5 ng/ml can be considered as the range for the test to be positive. In clinically suspected cases of cervical cancer, levels more than 4.8 ng/ml can be considered for the diagnosis as point of care test.
Radiotherapy for locally advanced unresectable gallbladder cancer - A way forward
Authors: Sinha Shwetabh , Engineer Reena , Ostwal Vikas , Ramaswamy Anant , Chopra Supriya , Shetty Nitin 
Published: January 2023

Background:
For nonmetastatic locally advanced gallbladder cancer (LAGBC) which remains unresectable and nonmetastatic after chemotherapy, there is no consensus on whether to continue chemotherapy or add local radiotherapy (RT) for improving outcomes.

Materials and Methods:
Forty-five patients of surgically unresectable nonmetastatic LAGBC were analyzed. Twenty patients did not receive RT (no RT cohort) and received only chemotherapy, while 25 patients received RT (RT cohort) with conformal techniques along with concurrent gemcitabine-based chemotherapy. No RT and RT cohorts were compared for disease-related outcomes and toxicities.

Results:
Median follow-up of the entire cohort was 11.5 months. Two-year progression-free survival (18.6% vs. 0%, P = 0.0001) and overall survival (37.3% vs. 5%, P = 0.0001) were significantly better in the RT cohort as compared to a no RT cohort. More number of patients had locoregional progression in the no RT cohort (85% vs. 32%, P = 0.0002). Radiation-induced acute and late gastrointestinal toxicity ≥ RTOG Grade 3 were seen in one and two patients, respectively.

Conclusion:
Addition of local RT to chemotherapy improves the survival outcomes and can be considered as a definite treatment modality for nonmetastatic LAGBC patients not amenable to surgery who have responded to chemotherapy.
