PurposeTobacco use remains the leading preventable cause of death in France, with 75,000 deaths each year. France aims to reduce smoking and achieve a smoke-free generation by 2032. However, recent tobacco industry innovations which mainly target young people, could undermine this goal. The main objective of this study is to assess the knowledge and consumption patterns of the “puff” among French adolescents in 2022.MethodsA cross-sectional study using a structured online survey on a representative sample of 400 adolescents aged 13 to 16 years was conducted from July 4th to 20th, 2022.ResultsAround 66% of adolescents reported having heard of the puff”, and one in ten having tried it. Slightly fewer of them have tried cigarettes; 89.6% of experimenters reported that it allowed them to explore unique flavors, 81.9% found it fun to play with the puff-cloud, and 94.5% of regular consumers considered it a stylish or cool product. 76% of adolescents believe that the puff is dangerous to their health, 71.6% describe it as a polluting device, and 62.8% think it’s a gadget.ConclusionThe “puff” is widely known by French adolescents and more commonly used than cigarettes, due, in part, to marketing specifically designed to target youth. That is why it could represent a threat to the smoke-free generation objectives. Public health policy could be informed by the ecological awareness of adolescents as a new lever of counter-influence to prevent this kind of consumption, as did ACT with the #stopcigarettespollution prevention campaign.

Abstract Background Nursing homes (NHs) have been particularly affected by COVID-19. The aim of this study is to estimate the burden of COVID-19 and to investigate factors associated with mortality during the first epidemic wave in a large French NHs network. Methods An observational cross-sectional study was conducted in September-October 2020. 290 NHs were asked to complete an online questionnaire covering the first epidemic wave on facilities and resident characteristics, number of suspected/confirmed COVID-19 deaths, and preventive/control measures taken at the facility level. Data were crosschecked using routinely collected administrative data on the facilities. The statistical unit of the study was the NH. Overall COVID-19 mortality rate was estimated. Factors associated with COVID-19 mortality were investigated using a multivariable multinomial logistic regression. The outcome was classified in 3 categories: “no COVID-19 death in a given NH”, occurrence of an “episode of concern” (at least 10% of the residents died from COVID-19), occurrence of a “moderate episode” (deaths of COVID-19, less than 10% of the residents). Results Of the 192 (66%) participating NHs, 28 (15%) were classified as having an “episode of concern”. In the multinomial logistic regression, moderate epidemic magnitude in the NHs county (adjusted OR = 9.3; 95%CI=[2.6–33.3]), high number of healthcare and housekeeping staff (aOR = 3.7 [1.2–11.4]) and presence of an Alzheimer’s unit (aOR = 0.2 [0.07–0.7]) were significantly associated with an “episode of concern”. Conclusions We found a significant association between the occurrence of an “episode of concern” in a NH and some of its organizational characteristics and the epidemic magnitude in the area. These results can be used to improve the epidemic preparedness of NHs, particularly regarding the organization of NHs in small units with dedicated staff. Brief summary Factors associated with COVID-19 mortality and preventive measures taken in nursing homes in France during the first epidemic wave.

Abstract Background To ensure the success of COVID-19 vaccination, public authorities need to have the support of the entire population and build vaccine confidence. Identifying and understanding the determinants of vaccine acceptance is essential for conducting vaccine strategy. The aim was to estimate vaccine hesitancy among healthcare students in France and to investigate the associated factors. Methods A web-based cross-sectional study was conducted in a large French University in greater Paris area, among 4927 healthcare students from the different training courses such as medicine studies, midwifery studies, physiotherapy studies, nurse studies and others health studies. The study was conducted between January 21 and February 8, 2021 based on a questionnaire including 25 single or multiple-choice questions, made using the free software Limesurvey. The link of the questionnaire was distributed to the students by the teachers and the student associations. The SAGE group definition of vaccine hesitancy was used. All estimates were weighted using the gender and training courses category of all healthcare students registered for the 2020–2021 year. Crude and adjusted weighted odds ratio (wOR) and 95% confidence interval (95%CI) were estimated using logistic regression. Results A total of 1465 healthcare students answered. A proportion of 44.5% (95%CI = [41.7–47.3]) of them were considered as hesitant. Women were more hesitant (50.9, 95%CI = [48.0–53.9]) than men (21.6, 95%CI = [15.2–28.0]). Vaccine hesitancy was significantly associated with gender (wOR = 0.27, 95%CI = [0.18–0.39]) and training courses: medical students were less likely to be hesitant than students in the common and first year of several health studies (wOR = 0.48, 95%CI = [0.33–0.70]) while nursing students were more than 5 times more likely to be hesitant (wOR = 5.20, 95%CI = [3.71–7.28]). Students who did an internship during the epidemic (wOR = 0.53, 95%CI = [0.41–0.69]) and who downloaded the mobile contact-tracing mobile app “TousAntiCovid” (wOR = 0.34, 95%CI = [0.26–0.44]) were significantly less likely to be hesitant. Conclusions Overall vaccine hesitancy among healthcare students was high, substantial differences were found between training courses. To reduce these disparities, interdisciplinary lectures on vaccines for all healthcare students may be implemented and evaluated.

The COVID-19 pandemic is a unique crisis challenging healthcare institutions as it rapidly overwhelmed hospitals due to a large influx of patients. This major event forced all the components of the healthcare systems to adapt and invent new workflows. Thus, our tertiary care hospital was reorganized entirely. During the cruising phase, additional staff was allocated to a one-building organization comprising an intensive care unit (ICU), an acute care unit, a physical medicine and rehabilitation unit, and a COVID-19 screening area. The transfer of patients from a ward to another was more efficient due to these organizations and pavilion structure. The observed mortality was low in the acute care ward, except in the palliative unit. No nosocomial infection with SARS-CoV-2 was reported in any other building of the hospital since this organization was set up. This type of one-building organization, integrating all the components for comprehensive patient care, seems to be the most appropriate response to pandemics.

BackgroundSyndromic surveillance systems have been developed in recent years and are now increasingly used by stakeholders to quickly answer questions and make important decisions. It is therefore essential to evaluate the quality and utility of such systems. This study was designed to assess a syndromic surveillance system based on emergency departments' (ED) morbidity rates related to the health effects of heat waves. This study uses data collected during the 2006 heat wave in France.MethodsData recorded from 15 EDs in the Ile-de-France (Paris and surrounding area) from June to August, 2006, were transmitted daily via the Internet to the French Institute for Public Health Surveillance. Items collected included diagnosis (ICD10), outcome, and age. Several aspects of the system have been evaluated (data quality, cost, flexibility, stability, and performance). Periods of heat wave are considered the most suitable time to evaluate the system.ResultsData quality did not vary significantly during the period. Age, gender and outcome were completed in a comprehensive manner. Diagnoses were missing or uninformative for 37.5% of patients. Stability was recorded as being 99.49% for the period overall. The average cost per day over the study period was estimated to be euro287. Diagnoses of hyperthermia, malaise, dehydration, hyponatremia were correlated with increased temperatures. Malaise was most sensitive in younger and elderly adults but also the less specific. However, overall syndrome groups were more sensitive with comparable specificity than individual diagnoses.ConclusionThis system satisfactorily detected the health impact of hot days (observed values were higher than expected on more than 90% of days on which a heat alert was issued). Our findings should reassure stakeholders about the reliability of health impact assessments during or following such an event. These evaluations are essential to establish the validity of the results of syndromic surveillance systems.

L’auteur presente un bilan, 30 ans apres la loi Evin. Pour cela, il met en avant son heritage qui se retrouve dans trois dimensions selon lui. Tout d’abord, dans une dimension epidemiologique puisque la loi Evin a cree une rupture dans la consommation de tabac en France. Puis, une dimension politique dans la mesure ou la loi a permis de repousser la puissance des lobbies. Enfin, sous la forme d’un heritage porte ouverture vers le futur en etant l’axe majeur de prevention pour sortir du tabac. L’auteur precise tout de meme la fragilite de ce texte bien que depuis 30 ans, elle s’adapte aux evolutions du marche.

IS DE-NORMALIZING TOBACCO AND ITS INDUSTRY A WINNING APPROACH? The so-called "denormalization" approach has progressively imposed itself in the field of tobacco control. This strategy is no longer limited to the health and individual implications of smoking but renews the fight against tobacco by considering it as a social problem. It is therefore a question of attacking the industry's influencing practices, and even appropriating them in campaigns linking the tobacco issue to contemporary struggles such as children's rights, climate change or gender equality. Denormalization is different from previous modes of action. Three American programs are considered to be the founders of this concept, which has recently been considered and practiced in France by ACT (Alliance contre le Tabac).DÉNORMALISER LE TABAC ET SON INDUSTRIE, UNE APPROCHE GAGNANTE ? L’approche dite de « dénormalisation » s’est progressivement imposée dans le champ de la lutte contre le tabac. Ensemble varié de pratiques d’influence, cette stratégie n’entend plus se limiter aux seules implications sanitaires et individuelles du problème tabagique, mais bien renouveler la lutte contre le tabac en considérant ce dernier comme un problème social. Il s’agit dès lors de contrecarrer les pratiques d’influence de l’industrie du tabac en mettant en lumière, par les mêmes outils, les conséquences sociétales de ses activités jusqu’alors méconnues du grand public : atteintes aux droits humains, dégradation de l’environnement et aggravation des inégalités économiques et sociales. La dénormalisation se distingue des modes d’action antérieurs. Trois programmes américains sont considérés comme fondateurs de ce concept qui est, depuis peu, également envisagé et pratiqué en France par l’Alliance contre le tabac (ACT).

International audience; ackground: Familial hypercholesterolaemia (FH) is responsible for severe hypercholesterolaemia and premature cardiovascular morbidity and mortality. The first clinical event is typically an acute coronary syndrome. Unfortunately, FH is largely underdiagnosed in the general population.Aims: To assess the prevalence of clinical FH among patients with premature (aged≤50 years) acute myocardial infarction (MI) and compare it with FH prevalence in a control population.Methods: We reviewed in our database all patients with premature MI (aged≤50 years) referred to Ambroise Paré Hospital from 2014 to 2018. FH prevalence was estimated via the Dutch Lipid Clinic Network score, based on personal and family history of premature cardiovascular disease and low-density lipoprotein cholesterol concentrations. FH was "possible" with a score between 3 and 5 points, "probable" with a score between 6 and 8 and "definite" with a score above 8. FH prevalence in young patients with MI was then compared with FH prevalence in a general population of the same age from the CARVAR 92 prospective cohort.Results: Of the 457 patients with premature MI, 29 (6%) had "probable" or "definite" FH. In the CARVAR 92 cohort, 16 (0.16%) of 9900 subjects aged≤50 years had "probable" or "definite" FH. FH prevalence was 39 times greater among patients with premature MI than in the control population (P30-fold more common in patients referred for premature MI than in the general population; this highlights the need for FH screening after a first MI to enhance lipid-lowering therapy and allow early identification of family members.

According to the World Health Organization, air pollution is responsible for 90 % of deaths in Africa. However, limited data on exposure to air pollution is available, and studies are rare, particularly in French-speaking Africa. This study aims to investigate the impact of air pollution on mortality in 12 French-speaking African countries (Algeria, Burkina Faso, Burundi, Cameroon, Guinea, Ivory Coast, Madagascar, Mali, Morocco, Democratic Republic of Congo, Senegal, Tunisia). Using data from the Institute for Health Metrics and Evaluation (IHME), annual concentrations of the PM2.5 pollutant from different cities were integrated into a spatial interpolation model (IDW) at the scale of each country. The interpolation was validated using cross-validation models. For each of the considered cardiorespiratory diseases (LRI, stroke, COPD, IHD), the attributable mortality fraction was estimated using literature data and population exposure calculated using demographic data from each country. Large variations in ambient PM2.5 concentration between the 12 countries are observed, with concentrations ranging from 1.76 μg/m3 in Morocco to 64.99 μg/m3 in Cameroon. Concentrations are higher in West Africa than in Central or North Africa. In 2019, 136 457 deaths attributable to air pollution were recorded in the 12 countries: 40.8 % from ischemic heart disease, 38.5 % from stroke, 13.2 % from lower respiratory infections and 7.5 % from chronic obstructive pulmonary disease. Our model allowed us to obtain a spatial distribution and the number of deaths related to air pollution. However, the estimation of the health impact from air pollution could be improved by more systematic and comprehensive local exposure assessments from a robust air quality monitoring system.

Adolescents turning into smokers in france .Tobacco kills more than 75,000 people in France each year. Among them, a large majority started their smoking history as an adolescent. More than half of 17-years-old have already tried tobacco and 25.1% of them report daily smoking. This is the lowest prevalence of daily smoking observed in France for 20 years. The daily consumption of 16-years-old decreased from 31% in 1995 to 12% in 2019, placing France in the European average. The initiation of regular tobacco consumption results from complex combinations of social (family, peers), environmental (passive exposure, accessibility, and marketing of products) and individual elements. Passive smoking in the family sphere and the influence of peers, which is most prevalent in adolescence, are two decisive determinants of future adolescent use of cigarette. The study of the entrance into smoking in adolescence should help to adapt preventive strategies to achieve a "tobacco-free generation"."Entrée des adolescents dans le tabagisme en france. Le tabac tue en France chaque année plus de 75 000 personnes. Parmi elles, une très large majorité a commencé son histoire tabagique dès l’adolescence. Plus de la moitié des jeunes de 17 ans ont déjà essayé le tabac et 25,1 % d’entre eux déclarent fumer quotidiennement. Il s’agit de la prévalence de tabagisme quotidien la plus faible observée en France depuis 20 ans. La consommation quotidienne des jeunes de 16 ans est, quant à elle, passée de 31 % en 1995 à 12 % en 2019, plaçant la France dans la moyenne européenne. Le démarrage d’une consommation régulière de tabac résulte de combinaisons complexes entre des éléments sociaux (famille, pairs), environnementaux (exposition passive, accessibilité et marketing des produits) et individuels. Le tabagisme passif dans la sphère familiale et l’influence des pairs, majeure à l’adolescence, sont deux déterminants décisifs de la consommation future de l’adolescent. L’étude des modalités d’entrée dans le tabagisme à l’adolescence doit aider à adapter les stratégies préventives pour parvenir à une « génération sans tabac »."

Background Korian is a private group specializing in medical accommodations for elderly and dependent people. A professional data warehouse (DWH) established in 2010 hosts all of the residents’ data. Inside this information system (IS), clinical narratives (CNs) were used only by medical staff as a residents’ care linking tool. The objective of this study was to show that, through qualitative and quantitative textual analysis of a relatively small physiotherapy and well-defined CN sample, it was possible to build a physiotherapy corpus and, through this process, generate a new body of knowledge by adding relevant information to describe the residents’ care and lives. Methods Meaningful words were extracted through Standard Query Language (SQL) with the LIKE function and wildcards to perform pattern matching, followed by text mining and a word cloud using R® packages. Another step involved principal components and multiple correspondence analyses, plus clustering on the same residents’ sample as well as on other health data using a health model measuring the residents’ care level needs. Results By combining these techniques, physiotherapy treatments could be characterized by a list of constructed keywords, and the residents’ health characteristics were built. Feeding defects or health outlier groups could be detected, physiotherapy residents’ data and their health data were matched, and differences in health situations showed qualitative and quantitative differences in physiotherapy narratives. Conclusions This textual experiment using a textual process in two stages showed that text mining and data mining techniques provide convenient tools to improve residents’ health and quality of care by adding new, simple, useable data to the electronic health record (EHR). When used with a normalized physiotherapy problem list, text mining through information extraction (IE), named entity recognition (NER) and data mining (DM) can provide a real advantage to describe health care, adding new medical material and helping to integrate the EHR system into the health staff work environment.

Public health prevention requires early detection of disease outbreaks, whether naturally occurring or due to bioterrorism. Permanent surveillance and a network of laboratories are the two main pillars of effective outbreak management. Coordination of information, training, and procedures are under the responsibility of the French public health watch institute and the scientific advisory board for the Biotox-Piratox laboratory network. Protective capacities against bioterrorism are improving but efforts must continue.

The French "cancer fight plan" was launched 2 years ago and has given a new impulse to smoking prevention. Among the different measures proposed, increasing the tobacco price dramatically was the more efficient to reduce the smoking prevalence, and epidemiological effects already exist. In just 2 years, the smoking prevalence has fallen from 35.2 % to 30.4 % in the French adult population and that difference is more importance among youth. The prevalence has dropped from 44.5 % to 36.4 % in this category between 1999 and 2003 after several years of increasing. Health professionals are also concerning by this quick decrease as shown by several recent study. All of these developments are welcome but are very fragile and all of the aspects of prevention are still necessary.

Disability is a major public health issue in France. A large proportion of the population in France and throughout the world is affected by at least one form of disability and the healthcare system is increasingly involved in managing it. The constant improvement of the quality of care and the optimisation of resources are simultaneously targeted by the decision-makers who define health policies. The care pathways followed by patients with motor disabilities are becoming longer and more complex as life expectancy increases and medical techniques evolve. There are few tools and methods for analysing the individual trajectories of these patients.Furthermore, French hospitals have, through the Programme de Médicalisation du Système d'Information (PMSI), an exhaustive medico-administrative database collecting information on the venues of patients through the various medical services. This work explores the possibility of using this database, initially gathered for the economic purpose of invoicing the care provided, to develop epidemiological research tools designed to inform and facilitate the evolution of the organisation of care.This work focuses on patients with spinal cord injuries and those with traumatic brain injuries or neuromuscular disorders, who are particularly concerned by the consequences of their pathologies in terms of motor function. The study took place at the Raymond Poincaré Hospital in Garches (AP-HP, Hauts-de-Seine), which is considered to be the national reference hospital for the management of motor disability. The work consisted in exploring the possibility of using these databases. A method of identifying these patients through the diagnostic coding of hospital stays was implemented. The different hospital trajectories were reconstructed, classified into coherent groups of care consumption and compared with each other. Finally, a method for visualising the flows within the trajectories was used in order to facilitate their understanding and appropriation.The completion of these different stages confirmed the possibility of using hospital medico-administrative databases as epidemiological research tools in the field of motor disability., Le handicap représente une problématique majeure de santé publique en France. Une part importante de la population en France et dans le monde est concernée par au moins une forme de handicap et sa prise en charge par le système de santé occupe une place de plus en plus importante. L’amélioration constante de la qualité des soins et l'optimisation des ressources sont simultanément recherchées par les décideurs qui définissent les politiques de santé. Les parcours de soins suivis par les patients atteints d’un handicap moteur s’allongent et se complexifient concomitamment avec l’augmentation de l’espérance de vie et l’évolution des techniques médicales.

Ce travail explore la possibilité d’exploiter ces données, collectées initialement dans un objectif économique de facturation des soins prodigués, afin de développer des outils de recherche épidémiologique destinés à informer et faciliter l’évolution de l’organisation des soins.Ce travail s’intéresse aux patients blessés médullaires et ceux atteints d’un traumatisme crânien ou d’une affection neuromusculaire, particulièrement concernés par les conséquences de leurs pathologies sur le plan moteur.

French population is rapidly aging. Senior citizens ratio is increasing and our society needs to rethink its organization, taking into account this change, better knowing this fast growing population group.Even if numerous cohorts of elderly people already exist worldly with four in France and, even as they live in growing numbers in nursing homes and out-patient treatment clinics, knowledge of this population segment is still missing.Today several health and medico-social structures groups as Korian and Orpéa invest in big relational data bases enabling them to get real-time information about their patients/residents. Since 2010 all Korian residents’ files are dematerialized and accessible by requests. They contain at the same time, structured medico-social data describing the residents as well as their treatments and pathologies, but also free-textual data detailing their daily care by the medical staff.Through time and as the computerized resident file (DRI) was mainly conceived as a data base management application, it appeared essential to mine these data and build a decision-making tool intended to improve the care efficiency. The Ageing Well Institute becoming meanwhile the Korian Ageing Well Foundation chose then, working in a private/public partnership, to finance a research work intented to better understand these datas’ informative potential, to assess their reliability and response to public health threats. This research work and this thesis were then designed in several steps:-First, a content analysis of the data warehouse DRI, the objective being to build a research data base, with a social side and a health side. This was the first paper subject.-Then, by direct extraction of the residents’ socio-demographic information at nursing home (NH) entry, adding hospitalizations and deaths, and finally, by an iterative textual extraction process of the transmissions data and by using the Delphi method, we created twenty-four syndromes, added hospitalizations and deaths and built a syndromic data base, the Ageing Well data base. This information system of a new kind, allowed the constitution of a public health cohort for elderly people from the BBV residents’population and its syndromic longitudinal follow-up. The BBV was also scientifically assessed for surveillance and public health research through present situation analysis: content, periodicity and data quality. This cohort then gave us the opportunity to build a surveillance tool and follow the residents’ population in real-time by watching their 26 daily frequency syndromic distributions. The methodology for that assessment, Atlanta CDCs’ health surveillance systems method, was used for flu and acute gastro enteritis syndroms and was the second paper subject.-Finally, the building of a new public health tool: each syndrom’s distribution through time (transmissions dates) and space (transmissions NH ids) opened the research field to new data exploration methods. I used these to study different health problems afflicting senior citizens: frequent falls, cancer, vaccinations and the end of life.; La France connaît un vieillissement de sa population sans précédent. La part des séniors s’accroît et notre société se doit de repenser son organisation pour tenir compte de ce changement et mieux connaître cette population.De nombreuses cohortes de personnes âgées existent déjà à travers le monde dont quatre en France et, bien que la part de cette population vivant dans des structures d’hébergement collectif (EHPAD, cliniques de soins de suite) augmente, la connaissance de ces seniors reste lacunaire.Aujourd’hui les groupes privés de maisons de retraite et d’établissements sanitaires comme Korian ou Orpéa s’équipent de grandes bases de données relationnelles permettant d’avoir de l’information en temps réel sur leurs patients/résidents. Depuis 2010 les dossiers de tous les résidents Korian sont dématérialisés et accessibles par requêtes. Ils comprennent à la fois des données médico-sociales structurées décrivant les résidents et leurs traitements et pathologies, mais aussi des données textuelles explicitant leur prise en charge au quotidien et saisies par le personnel soignant.Au fil du temps et alors que le dossier résident informatisé (DRI) avait surtout été conçu comme une application de gestion de base de données, il est apparu comme une nécessité d’exploiter cette mine d’informations et de construire un outil d’aide à la décision destiné à améliorer l’efficacité des soins. L’Institut du Bien Vieillir IBV devenu entretemps la Fondation Korian pour le Bien Vieillir a alors choisi, dans le cadre d’un partenariat Public/Privé de financer un travail de recherche destiné à mieux comprendre le potentiel informatif de ces données, d’évaluer leur fiabilité et leur capacité à apporter des réponses en santé publique. Ce travail de recherche et plus particulièrement cette thèse a alors été pensée en plusieurs étapes.-D’abord l’analyse de contenu du data warehouse DRI, l’objectif étant de construire une base de données recherche, avec un versant social et un autre de santé. Ce fut le sujet du premier article.-Ensuite, par extraction directe des informations socio-démographiques des résidents dès leur entrée, de leurs hospitalisations et décès puis, par un processus itératif d’extractions d’informations textuelles de la table des transmissions et l’utilisation de la méthode Delphi, nous avons généré vingt-quatre syndromes, ajouté les hospitalisations et les décès et construit une base de données syndromique, la Base du Bien Vieillir (BBV) . Ce système d’informations d’un nouveau type a permis la constitution d’une cohorte de santé publique à partir de la population des résidents de la BBV et l’organisation d’un suivi longitudinal syndromique de celle-ci. La BBV a également été évaluée scientifiquement dans un cadre de surveillance et de recherche en santé publique au travers d’une analyse de l’existant : contenu, périodicité, qualité des données. La cohorte construite a ainsi permis la constitution d’un outil de surveillance. Cet échantillon de population a été suivi en temps réel au moyen des fréquences quotidiennes d’apparitions des 26 syndromes des résidents. La méthodologie d’évaluation était celle des systèmes de surveillance sanitaire proposée par le CDC d’Atlanta et a été utilisée pour les syndromes grippaux et les gastro entérites aiguës. Ce fut l’objet du second article.-Enfin la construction d’un nouvel outil de santé publique : la distribution de chacun des syndromes dans le temps (dates de transmissions) et l’espace (les EHPAD de transmissions) a ouvert le champ de la recherche à de nouvelles méthodes d’exploration des données et permis d’étudier plusieurs problématiques liées à la personne âgée : chutes répétées, cancer, vaccinations et fin de vie.
