Abstract
We describe an experimental setup designed for transport measurement of thin disordered superconducting films as a function of pressure up to several GPa. We use a specially designed single screw diamond anvil cell that allows the gradual increase of high pressure at cryogenic temperatures. By depositing amorphous films of disordered superconducting indium oxide directly on the diamond, we avoid the effect of pressure-induced structural changes in the substrate. Using this technique, we are able to drive thin films through a pressure tuned superconductor-insulator transition.

Abstract
BACKGROUND In colon cancer, tumor deposits (TD) are considered in assigning prognosis and staging only in the absence of lymph node metastasis (i.e. stage III pN1c tumors). We aimed to evaluate the prognostic value of the presence and the number of TD in patients with stage III, node-positive colon cancer. PATIENTS AND METHODS All participants from the CALGB/SWOG 80702 phase III trial were included in this post hoc analysis. Pathology reports were reviewed for the presence and the number of TD, lymphovascular and perineural invasion. Associations with disease-free survival (DFS) and overall survival (OS) were evaluated by multivariable Cox models adjusting for sex, treatment arm, T-stage, N-stage, lymphovascular invasion, perineural invasion and lymph node ratio. RESULTS Overall, 2028 patients were included with 524 (26%) TD-positive and 1504 (74%) TD-negative tumors. Of the TD-positive patients, 80 (15.4%) were node negative (i.e. pN1c), 239 (46.1%) were pN1a/b (<4 positive lymph nodes) and 200 (38.5%) were pN2 (≥4 positive lymph nodes). The presence of TD was associated with poorer DFS [adjusted hazard ratio (aHR) = 1.63, 95% CI 1.33-1.98] and OS (aHR = 1.59, 95% CI 1.24-2.04). The negative effect of TD was observed for both pN1a/b and pN2 groups. Among TD-positive patients, the number of TD had a linear negative effect on DFS and OS. Combining TD and the number of lymph node metastases, 104 of 1470 (7.1%) pN1 patients were re-staged as pN2, with worse outcomes than patients confirmed as pN1 (3-year DFS rate: 65.4% versus 80.5%, P = 0.0003; 5-year OS rate: 87.9% versus 69.1%, P = <0.0001). DFS was not different between patients re-staged as pN2 and those initially staged as pN2 (3-year DFS rate: 65.4% versus 62.3%, P = 0.4895). CONCLUSION Combining the number of TD and the number of lymph node metastases improved the prognostication accuracy of tumor-node-metastasis (TNM) staging.

Abstract
At the end of December 2019, China notified the World Health Organization about a viral pneumonia epidemic soon to be named COVID-19, of which the infectious agent, SARS-CoV-2, was rapidly identified. Less than one year later, published phase 3 clinical trials underlined the effectiveness of vaccines utilizing hitherto unusual technology consisting in injection of the messenger RNA (m-RNA) of a viral protein. In the meantime, numerous clinical trials had failed to identify a maximally effective antiviral treatment, and mass vaccination came to be considered as the strategy most likely to put an end to the pandemic. The objective of this text is to address and hopefully answer the questions being put forward by healthcare professionals on the different anti-SARS-CoV-2 vaccines as regards their development, their modes of action, their effectiveness, their limits, and their utilization in different situations; we are proposing a report on both today's state of knowledge, and the 14 February 2021 recommendations of the French health authorities.

Abstract
BACKGROUND Immunization is experienced as painful and may be responsible for needle fear and noncompliance. There are rare evidence-based methods to reduce pain and improve comfort during immunization. There are no French immunization guidelines summarizing the good practices, based on recent studies. This study focused on the methods used by physicians and how they compared with those validated by clinical trials. METHODS An online questionnaire was sent to the practitioners from the Infovac network, and a PubMed bibliographic search was conducted. RESULTS Almost 2000 doctors responded to this survey. Purging the needle was a habit in 77.9% of them and aspiration before injection in 21.1%. Only one-quarter of the responding doctors injected in the deltoid muscle between 15 and 24 months, and some injected in the buttocks at any age. Half of the physicians vaccinated infants in their parent's arms, children were seated with half of the pediatricians and only one-third of the general practitioners (GPs), and teenagers were seated when vaccinated by three-quarters of the doctors. Anesthetic creams were used by 46.6% of the physicians, mostly by pediatricians (61.9%), and for infants. Breastfeeding was suggested by three-quarters of the physicians for infants under 4 months of age, and sugared solutions were used by 55.5% of the pediatricians and 32.3% of the GPs. Half of the doctors used rocking and cuddling for babies under 24 months of age and toys between 11 and 24 months. CONCLUSION Many methods are available to distract and improve comfort during immunization. Physicians should choose those they prefer, adjusting for the child's age. There should be French guidelines for immunization techniques, based to the latest clinical surveys, to help improve immunization practice.

Abstract
We find significant differences between degradation and healing at the surface or in the bulk for each of the different APbBr3 single crystals (A = CH3NH3+, methylammonium (MA); HC(NH2)2+, formamidinium (FA); and cesium, Cs+). Using 1- and 2-photon microscopy and photobleaching we conclude that kinetics dominate the surface and thermodynamics the bulk stability. Fluorescence-lifetime imaging microscopy, as well as results from several other methods, relate the (damaged) state of the halide perovskite (HaP) after photobleaching to its modified optical and electronic properties. The A cation type strongly influences both the kinetics and the thermodynamics of recovery and degradation: FA heals best the bulk material with faster self-healing; Cs+ protects the surface best, being the least volatile of the A cations and possibly through O-passivation; MA passivates defects via methylamine from photo-dissociation, which binds to Pb2+. DFT simulations provide insight into the passivating role of MA, and also indicate the importance of the Br3- defect as well as predicts its stability. The occurrence and rate of self-healing are suggested to explain the low effective defect density in the HaPs and through this, their excellent performance. These results rationalize the use of mixed A-cation materials for optimizing both solar cell stability and overall performance of HaP-based devices, and provide a basis for designing new HaP variants.

Abstract
Background DNA mismatch repair system deficiency (dMMR) is found in 15% of colorectal cancers (CRCs). Two methods are used to determine dMMR, immunohistochemistry (IHC) of MMR proteins and molecular testing of microsatellite instability (MSI). Only studies with a low number of patients have reported rates of discordance between these two methods, ranging from 1% to 10%. Materials and methods Overall, 3228 consecutive patients with CRCs from two centers were included. Molecular testing was carried out using the Pentaplex panel and IHC evaluated four (MLH1, MSH2, MSH6, and PMS2; cohort 1; n = 1085) or two MMR proteins (MLH1 and MSH2; cohort 2; n = 2143). The primary endpoint was the rate of discordance between MSI and MMR IHC tests. Results Fifty-one discordant cases (1.6%) were initially observed. Twenty-nine out of 51 discordant cases were related to IHC misclassifications. In cohort 1, after re-reading IHC and/or carrying out new IHC, 16 discordant cases were reclassified as nondiscordant. In cohort 2, after the addition of MSH6/PMS2 IHC and re-examination, 13 were reclassified as nondiscordant. In addition, 10 misclassifications of molecular tests were identified. Finally, only 12 discordant cases (0.4%) remained: 5 were proficient MMR/MSI and 7 were dMMR/microsatellite stable. Conclusions Our study confirmed the high degree of concordance between MSI and MMR IHC tests. Discordant cases must be reviewed, and if needed, tests must be repeated and analyzed by an expert team. Concordance between MMR IHC (four proteins) and MSI molecular testing (Pentaplex) is superior to 98% in CRC cases Most discordant cases are related to misinterpretation of the tests, which may lead to clinical management errors. Discordant cases must be reviewed and tests must be repeated because most cases will be reclassified as nondiscordant.

Abstract
This is a translation of the paper “Recommendations for the application and follow-up of quality controls in medical biology laboratories” published in French in the journal Annales de Biologie Clinique (Recommandations pour la mise en place et le suivi des contrôles de qualité dans les laboratoires de biologie médicale. Ann Biol Clin (Paris). 2019;77:577-97.). The recommendations proposed in this document are the result of work conducted jointly by the Network of Accredited Medical Laboratories (LABAC), the French Society of Medical Biology (SFBC) and the Federation of Associations for External Quality Assessment (FAEEQ). The different steps of the implementation of quality controls, based on a risk analysis, are described. The changes of reagent or internal quality control (IQC) materials batches, the action to be taken in case of non-conform IQC results, the choice of external quality assessment (EQA) scheme and interpretation of their results as well as the new issue of analyses performed on several automatic systems available in the same laboratory are discussed. Finally, the concept of measurement uncertainty, the robustness of the methods as well as the specificities of near-patient testing and rapid tests are described. These recommendations cannot apply for all cases we can find in medical laboratories. The implementation of an objective alternative strategy, supported with documented evidence, might be equally considered.

Abstract
PURPOSE To evaluate the utility of mural and extramural sonographic features of Crohn's Disease as potential imaging biomarkers of inflammation and fibrosis against whole-mount histological sections. METHODS Twelve Crohn's disease patients (Mean age 35(25-69), 7 males) underwent small bowel ultrasound prior to small bowel resection. Two radiologists in consensus graded multiple parameters including mural, mucosal and submucosal thickness, submucosal/mesenteric echogenicity and clarity and mural Doppler signal in 50 selected bowel cross-sections. Matching with histological sampling sites was facilitated via scanning of the resected specimen. A histopathologist scored acute and chronic inflammation, and fibrosis (using histological scoring systems) following analysis of whole mount block sections. The association between sonographic observations and histopathological scores was examined via univariable and multivariable analysis. RESULTS In univariate analyses, bowel wall thickness (regression co-efficient and 95% CI 0.8 (0.3, 1.3) p = 0.001), mesenteric fat echogenicity (8.7(3.0, 14.5) p = 0.005), submucosal layer thickness (7.4(1.2, 13.5) p = 0.02), submucosal layer clarity (4.4(0.6, 8.2) p = 0.02) and mucosal layer thickness (4.6(1.8, 7.4) p = 0.001) were all significantly associated with acute inflammation. Mesenteric fat echogenicity (674(8.67, 52404) p = 0.009), submucosal layer thickness (79.9(2.16, 2951) p = 0.02) and mucosal layer thickness (13.6(1.54, 121) p = 0.02) were significantly associated with chronic inflammation. Submucosal layer echogenicity (p = 0.03), clarity (25.0(1.76, 356) p = 0.02) and mucosal layer thickness (53.8(3.19, 908) p = 0.006) were significantly associated with fibrosis. In multivariate analyses, wall and mucosal thickness remained significantly associated with acute inflammation (p = 0.02), mesenteric fat echogenicity with chronic inflammation (p = 0.009) and mucosal thickness (p = 0.006) with fibrosis. CONCLUSION Multiple sonographic parameters are associated with histological phenotypes in Crohn's disease although there is overlap between ultrasonic stigmata of acute inflammation, chronic inflammation and fibrosis.

Abstract
OBJECTIVE Non-Alcoholic fatty liver disease (NAFLD) is becoming the most common liver disease in Western populations. While obesity and metabolic abnormalities are highly frequent in bipolar disorders (BD), no studies have been performed to estimate the prevalence of NALFD in individuals with BD. The aim of our study is to estimate the prevalence of NAFLD and to identify the potential associated risk factors in a large sample of BD individuals. METHODS Between 2009 and 2019, 1969 BD individuals from the FACE-BD cohort were included. Individuals with liver diseases, Hepatitis B or C, and current alcohol use disorders were excluded from the analyses. A blood sample was drawn from participants. Screening of NAFLD was determined using fatty liver index (FLI). Individuals with FLI> 60 were considered as having NAFLD. RESULTS The prevalence of NAFDL in this sample was estimated at 28.4%. NAFLD was observed in 40% of men and 21% of women. NAFLD was independently associated with older age, male gender, sleep disturbances, and current use of atypical antipsychotics or anxiolytics. As expected, the prevalence of NALFD was also higher in individuals with overweight and in those with metabolic syndrome. CONCLUSIONS This study reinforces the view that individuals with BD are highly vulnerable to metabolic and cardiovascular diseases. The prevalence of NAFLD in individuals with BD was two times higher than the prevalence reported in the general population. The regular screening of the MetS in individuals with BD should be therefore complemented by the additional screening of NAFLD among these vulnerable individuals.

Abstract
BACKGROUND Endoscopic follow-up after sleeve gastrectomy (SG) sometime reveals worrisome findings as the presence of major digestive lesions such as esophagitis, Barrett's esophagus (BE), and also esophageal cancer. OBJECTIVES The aim of this study was to investigate the frequency and severity of esophageal and gastric lesions after SG. METHODS Our team collected the results of esogastric endoscopies performed on patients who underwent SG up to five years before in our hospital, from April 2010 to August 2014. Summons were sent by mail to all patients operated on between those dates. The results were collected from January 2018 to June 2019. RESULTS Of the 765 patients who underwent SG up to five years before, only 78 (10.2%) agreed to undergo an upper digestive endoscopy. The average age before surgery was 51 years (range: 25-70 years). The mean preoperative body mass index (BMI) was 44.2±4.6kg/m2. For 12 out of these 78 patients (15.4%) it was revisional surgery: 9 SG after gastric banding, and 3 revisional SG (Re-SG). With an average follow-up of 6.3±0.8 years, the endoscopic results of the 78 patients were found to be normal in 31 cases (39.7%): gastritis was found in 28 patients (35.9%), severe grade C or D esophagitis was found in 15 cases (19.2%), hiatal hernia in 18 cases (23.1%), a benign gastric polyp in 2 cases (2.6%). Of the 28 patients with gastritis, HelicobacterPylori was detected in 8 cases (28.6%). No cancer was diagnosed, and BE after SG was found in only one case (1.3%) (normal before surgery). Six of 15 patients with esophagitis (40%) had reflux symptoms. Fourteen of these patients (93.3%) developed de novo esophagitis. CONCLUSION Only 10.2% of operated patients agreed to a long-term esogastric endoscopy. The frequency and severity of endoscopic anomalies observed with an average follow-up of more than 6 years pleads for a policy of systematic upper endoscopies of long-term control after SG.

Abstract
OBJECTIVE Monitoring of vaccination coverage rates (VCRs) is essential to assess the implementation of a country's vaccine policy and its effectiveness. Through the French Vaccinoscopy study, we measured the evolution of VCRs as well as mothers' opinion towards vaccination between 2008 and 2018, before and after implementation of infant mandatory vaccination extension. METHODS This is a study based on an internet-standardised questionnaire. In 2018, a representative sample of 3000 mothers of infants 0 to 35 months of age answered on their opinion on vaccination and reported all vaccinations recorded in their child's health record. RESULTS On the period considered, infant VCRs were stable and high for diphtheria, tetanus, poliomyelitis, pertussis and pneumococcus components and progressed for measles, mumps rubella, 2 doses at 24 months of age from 45.3% in 2008 to 81.0% in 2018, hepatitis B (HepB) complete primovaccination at 6 months of age from 45.9% in 2008 to 86.3% in 2017 and 95.5% in 2018, and meningococcus C (MenC) 1 dose at 6 months of age from 43.0% in 2017 to 74.2% in 2018. In 2018, 69.0% of mothers were in favour of vaccination while this rate dropped from 80.2% in 2012 to 64.0% in 2017, and 80.8 to 89.6% perceived HepB, MenC measles and pertussis vaccinations as useful/essential, percentages in progress versus 2017. CONCLUSION Following the implementation of infant mandatory vaccination in 2018, proportion of mothers in favour of vaccination increased significantly. HepB and MenC VCRs significantly progressed between 2017 and 2018.

Abstract
OBJECTIVE We aimed at identifying distinct trajectories of functioning and at describing their respective clinical characteristics in a cohort of individuals with bipolar disorders. METHODS We included a sample of 2351 individuals with bipolar disorders who have been followed-up to 3 years as part as the FondaMental Advanced Centers of Expertise in Bipolar Disorders cohort. Global functioning was measured using the Functioning Assessment Short Test. We used latent class mixed models to identify distinct longitudinal trajectories of functioning over 3 years. Multivariable logistic regression models were used to identify the baseline factors that were associated with the membership to each trajectory of functioning. RESULTS Three distinct trajectories of functioning were identified: (1) a majority of individuals (72%) had a stable trajectory of mild functional impairment, (2) 20% of individuals had a stable trajectory of severe functional impairment and (3) 8% of individuals had a trajectory of moderate functional impairment that improved over time. The membership to a trajectory of stable severe versus stable mild functional impairment was associated with unemployment, a higher number of previous hospitalizations, childhood maltreatment, a higher level of residual depressive symptoms, higher sleep disturbances, a higher body mass index and a higher number of psychotropic medications being prescribed at baseline. The model that included these seven factors led to an area under the curve of 0.85. CONCLUSION This study enabled to stratify individuals with bipolar disorders according to three distinct trajectories of functioning. The results regarding the potential determinants of the trajectory of severe functional impairment needs to be replicated in independent samples. Nevertheless, these potential determinants may represent possible therapeutic targets to improve the prognosis of those patients at risk of persistent poor functioning.

Abstract
The educational and social benefits provided by school far outweigh the risks of a possible COVID-19 contamination of children in school environments or in daycare centers. Following summer break, the back-to-school period in France is taking place in the context of an increasing viral spread and requires strict adherence to health measures to limit the risk of outbreaks in communities. Based on a critical update of the role of children in the transmission of the infection, and of children's susceptibility to infection, the French Pediatric Society published practical guidelines for school re-entry and the management of COVID-19 infections in schools.

Abstract
Les infections liées à l’herpès virus humain (HSV), au virus de la varicelle et du zona (VZV) et au virus de la grippe (Influenza A et B) sont très fréquentes en pédiatrie et sont le plus souvent bénignes avec une guérison spontanée. L’utilisation des antiviraux antigrippaux (inhibiteurs de neuraminidase) a été étudiée dans de larges essais randomisés et fait l’objet de recommandations nationales et internationales. Celle des anti-HSV et anti-VZV n’a pas fait l’objet d’études de la même ampleur et de ce fait, leur prescription est plus discutée avec des bénéfices moins bien définis et variables (à l’exception des infections néonatales et/ou neuro-méningées). L’objectif de cette mise au point est donc de proposer une synthèse des données disponibles dans la littérature concernant les indications des antiviraux en pratique de ville pour les infections liées à l’HSV (gingivostomatite, herpès récurrent, faux panaris herpétique), au VZV (varicelle, zona) et à la grippe.
