RESUMEN
OBJECTIVE: To estimate the prevalence and trend of congenital eye anomalies (CEAs) and the rate of prenatal diagnosis over a 10-year period. DESIGN: Retrospective population-based registry study. SETTING: All maternity units in Paris, France, from 2010 to 2020. POPULATION: A cohort of 115 cases of CEA detected among all live births or stillbirths, after 22 weeks of gestation, and terminations of pregnancy. METHODS: The total prevalence of CEAs and prevalence of each specific CEA were calculated using 95% Poisson exact confidence intervals. MAIN OUTCOME MEASURES: The total prevalence of CEAs and the proportion of prenatal diagnosis of CEAs, and their evolution. RESULTS: The prevalence of CEAs was 4.1 (95% CI 3.4-5.0) cases, ranging between 3.1 and 5.7 cases, per 10 000 births. CEAs were prenatally diagnosed in 23.5% of cases. CEAs were bilateral in 51 cases (44.3%), unilateral in 43 cases (37.4%) and missing or unknown in 21 cases (18.3%). Of those with CEAs, 20.9% had genetic anomalies and 53.0% had at least one other extraocular anomaly. When detected prenatally, CEAs were bilateral in 15 cases (55.6%), unilateral in eight cases (29.6%) and missing in the four remaining cases. The prenatal diagnosis rate of CEAs associated with genetic anomalies, CEA cases with at least one other malformation and isolated CEA cases were 29.2%, 26.2% and 13.3%, respectively. CONCLUSIONS: In total, 115 cases of CEAs were observed during the study period, representing a total prevalence of 4.1 cases per 10 000 births. The overall prenatal detection rate of CEAs in our population was 23.5%, which dropped to 13.3% for isolated cases of CEAs.

Neonatal herpes simplex virus (HSV) infection (HSV infection in infants less than 6 weeks of age) is rare but mortality and morbidity rates are high after disseminated disease and encephalitis. In France, the epidemiology is poorly described, and two decades ago, incidence was estimated to be 3 per 100,000 live births a year. We describe determinants, epidemiologic and clinical characteristics of neonatal HSV infection in a managed-care population attending in two major obstetric and paediatric centres, Paris, France, over a 10-year period. This retrospective case series study was conducted from 2013 to 2023, in infants less than 42 days of age who had virologically confirmed HSV infection. We report an overall rate of neonatal herpes of 5.5 per 100,000 live births a year and an incidence of symptomatic cases of 1.2 per 100,000 live births a year. HSV-1 was the major serotype involved (84.2%) and post-natal acquisition through the orolabial route reached 63.2%. All neonates who had neonatal HSV PCR screening (owing to clinical signs in parents) and who received prompt acyclovir treatment remained asymptomatic. Symptomatic forms accounted for 21.1% cases of the total and mortality was high (62.5% of symptomatic forms). Conclusion: This case series confirms that neonates at risk for HSV disease and poor outcome are those born to HSV-seronegative mothers, preterm infants, and those who received acyclovir after onset of symptoms (mainly because mothers did not present evidence of acute HSV infection). Our study confirms the major role of HSV-1 and the frequency of its early post-natal acquisition. What is known: ⢠Neonatal herpes simplex virus infection is rare but motality and morbidity rates are high after disseminted disease and encephalitis. National recommendations exist worldwide but mangement of this disease is not always easy. What is new: ⢠As in France epidemiology of neonatal herpes is poorly described, our report is potentially an important addition to the existing literature. Moreover, we describe local practice that may be useful to physicians.

BackgroundDuring the 2022 mpox outbreak in Europe, primarily affecting men who have sex with men, a limited number of cases among children and adolescents were identified. Paediatric cases from outbreaks in endemic countries have been associated with a higher likelihood of severe illness. Detailed clinical case descriptions and interventions in school settings before 2022 are limited.AimTo describe clinical characteristics of mpox cases among children (<â¯15 years) and adolescents (15-17 years) in the greater Paris area in France, and infection control measures in schools.MethodsWe describe all notified laboratory-confirmed and non-laboratory-confirmed cases among children and adolescents identified from May 2022 to July 2023, including demographic and clinical characterisation and infection control measures in school settings, i.e. contact tracing, contact vaccination, secondary attack rate and post-exposure vaccination uptake.ResultsNineteen cases were notified (13 children, 6 adolescents). Four adolescent cases reported sexual contact before symptom onset. Ten child cases were secondary cases of adult patients; three cases were cryptic, with vesicles on hands, arms and/or legs and one case additionally presented with genitoanal lesions. Five cases attended school during their infectious period, with 160 at-risk contacts identified, and one secondary case. Five at-risk contacts were vaccinated following exposure.ConclusionCases among children and adolescents are infrequent but require a careful approach to identify the source of infection and ensure infection control measures. We advocate a 'contact warning' strategy vs 'contact tracing' in order to prevent alarm and stigma. Low post-exposure vaccination rates are expected.

BackgroundSome migrant men who have sex with men (MSM) acquire HIV in France.AimsWe investigated, in migrant MSM receiving HIV care in France, the (i) rate of post-migration-HIV acquisition in France, (ii) delay between arrival and HIV acquisition and (iii) factors affecting HIV acquisition within 1 year after migration.MethodsThis cross-sectional study focused on ≥ 18-year-old MSM born outside France, receiving HIV care in the Paris region. Information on migration history, socioeconomic condition, sexual activity, and health was collected in May 2021-June 2022 through self-administered questionnaires and medical records. Post-migration-HIV-acquisition rate and delay between arrival in France and HIV acquisition were estimated from biographical data and CD4+ T-cell counts. Predictors of HIV acquisition within 1 year after migration were determined using logistic regression.ResultsOverall post-migration HIV-acquisition rate was 61.7% (715/1,159; 95%CI: 61.2-62.2), ranging from 40.5% (95%CI: 39.6-41.6) to 85.4% (95%CI: 83.9-86.0) in participants from Latin America and North Africa. Among post-migration-HIV acquisitions, those within 1 year after migration represented 13.1% overall (95%CI: 11.6-14.6), being highest in participants from sub-Saharan Africa (25%; 95%CI: 21.5-28.3). Participants ≥ 15-years old at migration, with post-migration-acquired HIV, had a 7.5-year median interval from arrival in France to HIV acquisition (interquartile range (IQR): 3.50-14.75). Older age at arrival, region of origin (sub-Saharan Africa and Asia), degree of social disadvantage and numbers of sexual partners were independently associated with acquiring HIV within 1 year in France.ConclusionOur findings may guide HIV prevention policies for most vulnerable migrants to Europe.

BackgroundWastewater surveillance is an effective approach to monitor population health, as exemplified by its role throughout the COVID-19 pandemic.AimThis study explores the possibility of extending wastewater surveillance to the Paris 2024 Olympic and Paralympic Games, focusing on identifying priority pathogen targets that are relevant and feasible to monitor in wastewater for these events.MethodsA list of 60 pathogens of interest for general public health surveillance for the Games was compiled. Each pathogen was evaluated against three inclusion criteria: (A) analytical feasibility; (B) relevance, i.e. with regards to the specificities of the event and the characteristics of the pathogen; and (C) added value to inform public health decision-making. Analytical feasibility was assessed through evidence from peer-reviewed publications demonstrating the detectability of pathogens in sewage, refining the initial list to 25 pathogens. Criteria B and C were evaluated via expert opinion using the Delphi method. The panel consisting of some 30 experts proposed five additional pathogens meeting criterion A, totalling 30 pathogens assessed throughout the three-round iterative questionnaire. Pathogens failing to reach 70% group consensus threshold underwent further deliberation by a subgroup of experts.ResultsSix priority targets suitable for wastewater surveillance during the Games were successfully identified: poliovirus, influenza A virus, influenza B virus, mpox virus, SARS-CoV-2 and measles virus.ConclusionThis study introduced a model framework for identifying context-specific wastewater surveillance targets for a mass gathering. Successful implementation of a wastewater surveillance plan for Paris 2024 could incentivise similar monitoring efforts for other mass gatherings globally.

BACKGROUND: Sjögren's disease is a heterogenous autoimmune disease with a wide range of symptoms-including dryness, fatigue, and pain-in addition to systemic manifestations and an increased risk of lymphoma. We aimed to identify distinct subgroups of the disease, using cluster analysis based on subjective symptoms and clinical and biological manifestations, and to compare the prognoses of patients in these subgroups. METHODS: This study included patients with Sjögren's disease from two independent cohorts in France: the cross-sectional Paris-Saclay cohort and the prospective Assessment of Systemic Signs and Evolution of Sjögren's Syndrome (ASSESS) cohort. We first used an unsupervised multiple correspondence analysis to identify clusters within the Paris-Saclay cohort using 26 variables comprising patient-reported symptoms and clinical and biological manifestations. Next, we validated these clusters using patients from the ASSESS cohort. Changes in disease activity (measured by the European Alliance of Associations for Rheumatology [EULAR] Sjögren's Syndrome Disease Activity Index [ESSDAI]), patient-acceptable symptom state (measured by the EULAR Sjögren's Syndrome Patient Reported Index [ESSPRI]), and lymphoma incidence during follow-up were compared between clusters. Finally, we compared our clusters with the symptom-based subgroups previously described by Tarn and colleagues. FINDINGS: 534 patients from the Paris-Saclay cohort (502 [94%] women, 32 [6%] men, median age 54 years [IQR 43-64]), recruited between 1999 and 2022, and 395 patients from the ASSESS cohort (370 [94%] women, 25 [6%] men, median age 53 years [43-63]), recruited between 2006 and 2009, were included in this study. In both cohorts, hierarchical cluster analysis revealed three distinct subgroups of patients: those with B-cell active disease and low symptom burden (BALS), those with high systemic disease activity (HSA), and those with low systemic disease activity and high symptom burden (LSAHS). During follow-up in the ASSESS cohort, disease activity and symptom states worsened for patients in the BALS cluster (67 [36%] of 186 patients with ESSPRI score <5 at month 60 vs 92 [49%] of 186 at inclusion; p<0·0001). Lymphomas occurred in patients in the BALS cluster (five [3%] of 186 patients; diagnosed a median of 70 months [IQR 42-104] after inclusion) and the HSA cluster (six [4%] of 158 patients; diagnosed 23 months [13-83] after inclusion). All patients from the Paris-Saclay cohort with a history of lymphoma were in the BALS and HSA clusters. This unsupervised clustering classification based on symptoms and clinical and biological manifestations did not correlate with a previous classification based on symptoms only. INTERPRETATION: On the basis of symptoms and clinical and biological manifestations, we identified three distinct subgroups of patients with Sjögren's disease with different prognoses. Our results suggest that these subgroups represent different heterogeneous pathophysiological disease mechanisms, stages of disease, or both. These findings could be of interest when stratifying patients in future therapeutic trials.

OBJECTIVES: To examine the association between life-course body silhouette changes and oral conditions in adulthood. METHODS: At study recruitment (2008-2012), 5430 adults underwent a full-mouth clinical examination and recalled their body silhouettes at ages 8, 15, 25, 35 and 45. Life-course trajectories of body silhouettes were computed using group-based trajectory modelling. Gingival inflammation, dental plaque, masticatory units, numbers of healthy, missing, decayed and filled teeth at study recruitment were clustered. The associations between body silhouette trajectories and clusters of oral conditions were assessed by multinomial logistic regression. RESULTS: The final analysis included 4472 participants. Five body silhouette trajectories were established: lean-stable (30.0%), lean-increased (19.3%), moderate stable (18.1%), lean-marked increased (25.8%) and heavy stable (6.7%). Three clusters of oral conditions were identified: optimal oral health and preserved masticatory capacity (70.0%, cluster 1), moderate oral health and moderately impaired masticatory capacity (25.4%, cluster 2) and poor oral health and severely impaired masticatory capacity (4.7%, cluster 3). Participants with a lean-increased trajectory were 58% more likely than those with a lean-stable trajectory to be in cluster 3 (aOR 1.58 [95% CI 1.07; 2.35]) relative to cluster 1, independently of covariates measured at study recruitment and including age, sex, smoking, socioeconomic status, BMI, hypertension, type 2 diabetes, cholesterol and triglycerides. CONCLUSIONS: A life-course lean-increased body silhouette trajectory is associated with higher likelihood of poor oral health and severely impaired masticatory capacity in adulthood.

Importance: Children with profound hearing loss (HL) and vestibular impairment have worse cochlear implant outcomes compared with those without vestibular impairment. However, the decision for cochlear implantation is rarely based on vestibular function assessment as a complement to audiologic testing. Objectives: To identify the prevalence of vestibular impairment according to HL origin and to assess the association between vestibular impairment and delayed posturomotor development in children with profound HL. Design, Setting, and Participants: This cohort study was conducted in a pediatric referral center for cochlear implantation in Paris, France, using medical records data on HL origin, vestibular assessment, and ages of developmental milestone achievement. The cohort included children with profound HL (loss >90 dB HL) who completed vestibular assessment prior to cochlear implantation between January 1, 2009, and December 31, 2019. Data analyses were conducted between January and June 2023. Main Outcomes and Measures: The primary outcome was prevalence of vestibular impairment according to HL origin. Children were classified into 3 groups according to their responses to vestibular testing: normal vestibular function (NVF), partially impaired vestibular function (PVF), and complete bilateral vestibular loss (CBVL). Generalized logit models were performed to evaluate the association between vestibular impairment and causes of HL as well as posturomotor development delay. Results: A total of 592 children were included (308 males [52.0%]; mean [SD] age, 38 [34] months). In children with documented HL origin (n = 266), 45.1% (120) had HL with genetic origin, 50.0% of which were syndromic (mainly Usher and Waardenburg syndromes) and 50.0% were nonsyndromic (mainly associated with connexin 26). Among patients with infectious HL origin (n = 74), 70.3% (52) had cytomegalovirus (CMV) infection. Vestibular impairment was found in 44.4% (263 of 592) of the children; it was mostly symmetrical in 88.9% (526) and was CBVL in 5.7% (34) of the cases. Vestibular impairment was present in 78.3% (47) of children with genetic syndromic HL (56.7% [34] with PVF; 21.7% [13] with CBVL) and in 69.2% (36) of children with CMV infection (57.7% [30] with PVF; 11.5% [6] with CBVL). Genetic syndromic HL origin was found to be more often associated with both PVF and CBVL than other HL causes. The odds of having delays in 4 developmental milestones (head holding, sitting, standing with support, and independent walking) were higher in both PVF and CBVL (eg, head-holding odds ratios: 2.55 and 4.79) compared with NVF, and the age of achieving these milestones was higher in CBVL than PVF (eg, head holding: 7.33 vs 4.03 years; P < .001). All 4 developmental milestones were associated with the degree of vestibular impairment. Conclusions and Relevance: This cohort study found that among children with profound HL, vestibular impairment was prevalent, varied according to HL origin, and associated with posturomotor development; while all developmental milestones were associated with vestibular impairment severity, not all HL causes were associated with vestibular impairment severity. Children with profound HL may benefit from complete vestibular assessment before cochlear implantation, which would support early and adapted management, such as physical therapy for CBVL and cochlear implantation strategy.

OBJECTIVES: The anticipated increase in international tourist flows and the first locally acquired dengue cases in the Paris region in October 2023 have raised concerns about potential arbovirus outbreaks during the 2024 Olympics. Unlike previous mass sporting events at risk of arbovirus outbreaks, Paris is a nonendemic arbovirus area, requiring a unique investigation. METHODS: Therefore, we analyzed factors conducive to possible arbovirus epidemics in temperate regions: vector distribution in the Paris area, seasonal global arboviral disease patterns, projected visitor demographics, and international flight bookings. RESULTS AND CONCLUSION: Our results suggest that the expected visitors' profile for the summer of 2024 should not increase the risk of arbovirus importation into the Paris region compared to a typical year. Conversely, the primary risk of arbovirus outbreaks is likely to come from within France, particularly from the French West Indies, where a notable, albeit declining, dengue outbreak is underway. Vigilant surveillance by French health authorities will ensure that this trend continues.

Athletes are vulnerable to Staphylococcus aureus infections due to skin-to-skin contact and skin abrasions during training and competitions involving sharied sport equipment or toiletries, which promote the spread of the bacteria between athletes and within sport teams. This results not only in higher prevalence of S.aureus carriage among athletes compared to the general population, but also in outbreaks of infections, particularly skin infections, within sports teams. To limit the spread of S. aureus among athletes, a decolonization protocol can be applied when clustered cases of S. aureus infections occur, especially if Panton-Valentine leukocidin-producing strains are implicated. Finally, to avoid exposing athletes to S.aureus transmission/colonization, it is recommended to establish strict and clearly formulated individual and collective hygiene rules and to regularly disinfect shared sports equipment.

INTRODUCTION: The prevalence of Barrett's esophagus (BE) in France is unknown. However, the management of dysplastic BE in expert centers is recommended and reduces the risk of developing invasive adenocarcinoma. Our aim was to determine the burden of BE patients in the Paris Region. METHODS: We performed a retrospective study using the data from electronic medical records from the data warehouse of the 39 Greater Paris public hospitals (Entrepôt de données de santé de l' Assistance Publique- Hôpitaux de Paris) for the year 2018, and used natural language processing to search for occurrences of Barrett's esophagus in endoscopy and pathology reports. RESULTS: we observed a 2.2 % prevalence of Barrett's esophagus. Patients with Barrett's esophagus were older, more frequently males, with a hiatal hernia, proton pump inhibitor users, and less frequently infected by H. Pylori. Gastro-esophageal reflux symptoms were not more frequently encountered in Barrett's patients. Eleven percent of patients with Barrett's esophagus had dysplasia or adenocarcinoma. DISCUSSION: Over 200 000 patients with Barrett's esophagus are expected in the Paris Region, of which 11 % harbor dysplasia or adenocarcinoma. This data should be taken into account to tailor healthcare offer in France.

OBJECTIVE: To prevent post-partum haemorrhage (PPH), national and international guidelines recommend the administration of a prophylactic injection of oxytocin after all vaginal births. Although additional maintenance oxytocin is not recommended in the immediate postpartum, its administration is quite common (30 % of French births in 2021). To assess in a single center, the frequency and determinants associated with the administration of maintenance oxytocin in immediate postpartum. STUDY DESIGN: A retrospective observational single-centre study was conducted in a tertiary-care university centre in Paris (France), with data from April-May 2022. All women who gave birth vaginally at or after 37 weeks, except for those with immediate PPH. Univariate and multivariate analysis were performed to compare determinants between the group receiving maintenance oxytocin and the control group without this intervention. A sensitivity analysis in a population of women at low risk of PPH was performed. Maternal, obstetrical, perinatal and organisational determinants were collected. RESULTS: This study included 584 patients, 278 (47.6 %) of whom received maintenance oxytocin. We observed a significantly higher rate of maintenance oxytocin administration to parous women (OR 1.57, 90 %CI 1.09-2.27) and women with a history of PPH (OR 2.88, 90 %CI 1.08-9.08). Additional maintenance oxytocin was also administered more often when the midwife handling the birth had more than 5 years of practice since completion of training (OR 1.77, 1.24-2.53) or during night-time births (OR 1.47, 90 %CI 1.03-2.10). CONCLUSION: Maintenance oxytocin administration is a frequent practice, performed for almost half the patients in our center. This practice is associated with maternal and obstetric factors, but also with health professionals' individual decisions and practices.

BACKGROUND: France has the sixth highest incidence of oropharyngeal cancer (OPC) in Europe, but the epidemiological impact of high-risk HPV (HR-HPV) remains poorly documented. The objective of our study was to assess the proportion of OPCs caused by HR-HPV in Paris, and its suburbs, over the four past decades. This area accounts for almost one-fifth of the total population of France. METHODS: OPCs diagnosed in 1981, 1986, 1991, 1996, 2001, 2006, 2011, 2016 and 2020/2021 in two of the main referral cancer centers for HNCs in Paris and its suburbs were retrieved from the tumor biobanks. HPV status was determined by p16-staining and HPV-DNA detection. Samples were considered HPV-driven if both assays were positive. Results were compared to the French cancer registry data. RESULTS: Samples from 697 OPC patients were assessed (including 82â¯% of all samples diagnosed in 2001, 2006, 2011, 2016, 2021). The proportion of HPV-driven cases rose from 2.7â¯% to 53â¯% between 1981 and 2021. HPV16 was the dominant genotype during the study period. Of patients with HPV-driven OPC, 81â¯% were male and 42â¯% were smokers versus 80â¯% and 92â¯% in their HPV-negative counterparts. The age of OPC patients increased significantly, during the study period, independent of their HPV status CONCLUSION: The proportion of HPV-driven OPCs has significantly increased in Paris and its suburbs, during the last four decades. OPCs has become the 2nd predominant type of head and neck cancer, in France. This may be linked to the rise in HPV-driven cases and the decrease of tobacco and alcohol consumption in men.

BACKGROUND: Recreational nitrous oxide (N2O) use has become more widespread worldwide, leading to an increase in myelopathies and peripheral neuropathies. The aim of this study was to describe clinical and socioeconomical characteristics of severe N2O-induced (NI) neurological disorders (NI-NDs), to determine its incidence in the Greater Paris area and to compare it with that of similar inflammatory neurological disorders. METHODS: We performed a retrospective multicentric cohort study of all adult patients with severe NI-NDs in the neurology and general internal medicine departments of the Greater Paris area from 2018 to 2021. The incidence was compared with that of non-NI-myelitis and Guillain-Barré syndrome (GBS) using a sample of 91,000 hospitalized patients sourced from health insurance data. RESULTS: Among 181 patients, 25% had myelopathy, 37% had peripheral neuropathy and 38% had mixed disease. Most were aged between 20 and 25 years, lived in socially disadvantaged urban areas, and exhibited high rates of unemployment (37%). The incidence of NI-NDs increased during 2020 and reached a peak mid-2021. The 2021 incidence in 20-25-year-olds was 6.15 [4.72; 8.24] per 100,000 persons for NI-myelopathy and 7.48 [5.59; 9.37] for NI-peripheral neuropathy. This was significantly higher than for non-NI-myelitis (0.35 [0.02; 2.00]) and GBS (2.47 [0.64; 4.30]). The incidence of NI-NDs was two to three times higher in the most socially disadvantaged areas. CONCLUSION: The recent increase in recreational N2O use has led to a rise in the incidence of severe NI-NDs, particularly in young adults with low socioeconomic status for whom NI-NDs strongly outweigh similar neurological disorders.

INTRODUCTION: Registries of congenital anomalies (CAs) play a key role in the epidemiological surveillance of CAs. The objective was to estimate the prevalence of CAs and proportions of prenatal diagnosis, terminations of pregnancy for fetal anomaly (TOPFA) and infant mortality in the Paris Registry of Congenital Malformations (remaPAR) over 40 years, from 1981 to 2020. MATERIAL AND METHODS: remaPAR records all births (live births, stillbirths ≥22 weeks of gestation and TOPFA at any gestational age) with CAs detected prenatally until the early neonatal period. We estimated the prevalence of CAs and proportions of prenatal diagnosis, TOPFA and infant mortality, overall and for a selected group of CAs in 3-year intervals. RESULTS: The prevalence of CAs remained stable during the study period: 2.9 % of total births and 2.1 % of live births. Genetic anomalies were the most frequent subgroup (about 23 %), followed by congenital heart defects (about 22 %) and limb defects (about 20 %). Among non-genetic anomalies, the prevalence per 10,000 births was the highest for hypospadias (about 18 %) and the lowest for bilateral renal agenesis (about 1 %). Prenatal diagnoses increased from about 17 % in the 1980s to approximately 70 % in the most recent period (2018-2020), whereas the proportion of early TOPFA <16 weeks of gestation increased from 0.4 % to 14 %. Infant mortality ranged from 0 % for transverse limb reduction defects to 86 % for hypoplastic left heart syndrome. CONCLUSION: The overall prevalence of CAs was fairly stable in Paris from 1981 to 2020. Prenatal diagnoses substantially increased, accompanied by much smaller increases in TOPFA.

BACKGROUND: Controlled donation after circulatory death (cDCD) in post-anoxic brain injury is a valuable source of organs that is still underused in some countries. We assessed the number of potential cDCD donors after out-of-hospital cardiac arrest (OHCA) in Paris and its suburbs and extrapolated the results to the French population. METHODS: Using the large regional registry of the Great Paris area, we prospectively included all consecutive adults with OHCA with a stable return of spontaneous circulation (ROSC) who ultimately died in the intensive care unit (ICU) after withdrawal of life-sustaining treatments (WLST) due to post anoxic brain injury. The primary endpoint was potential for organ donation by cDCD in this population. The number of potential cDCD donors was calculated and extrapolated to the entire French population. RESULTS: Between 2011 and 2018, 4638 patients with stable ROSC were admitted to ICUs after OHCA, and 3170 died in ICU, of which 1034 died after WLST due to post-anoxic brain injury. When considering French criteria, 421/1034 patients (41%) would have been potential cDCD donors (55 patients per year in a 4.67 million population). After standardization for age and sex, the potential for cDCD was 515 (95% CI 471-560) patients per year in France corresponding to an annual incidence of 1.18 per 100 000 inhabitants per year. CONCLUSIONS: Organ donation by cDCD after cardiac arrest could provide a large pool of donors in France.

OBJECTIVE: Little is known about the effect of gut microbial and extended-spectrum ß-lactamase-producing Enterobacterales (ESBL-E) carriage, particularly in the general population. The aim of this study was to identify microbiota signatures uniquely correlated with ESBL-E carriage. METHODS: We conducted a case-control study among individuals seeking care at the Sexual Health Clinic or Department of Infectious and Tropical Diseases, Saint-Antoine Hospital, Paris, France. Using coarsened exact matching, 176 participants with ESBL-carriage (i.e. cases) were matched 1:1 to those without ESBL-carriage (i.e. controls) based on sexual group, ESBL-E prevalence of countries travelled in <12 months, number of sexual partners in <6 months, geographic origin, and any antibiotic use in <6 months. 16S rRNA gene amplicon sequencing was used to generate differential abundances at the genus level and measures of α- and ß-diversity. RESULTS: Participants were mostly men (83.2%, n = 293/352) and had a median age of 33 years (interquartile range: 27-44). Nine genera were found associated with ESBL-E carriage: Proteus (p < 0.0001), Carnobacterium (p < 0.0001), Enterorhabdus (p 0.0079), Catonella (p 0.017), Dermacoccus (p 0.017), Escherichia/Shigella (p 0.021), Kocuria (p 0.023), Bacillus (p 0.040), and Filifactor (p 0.043); however, differences were no longer significant after Benjamini-Hochberg correction (q > 0.05). There were no differences between those with versus without ESBL-E carriage in measures of α-diversity (Shannon Diversity Index, p 0.49; Simpson Diversity Index, p 0.54; and Chao1 Richness Estimator, p 0.16) or ß-diversity (Bray-Curtis dissimilarity index, p 0.42). DISCUSSION: In this large carefully controlled study, there is lacking evidence that gut microbial composition and diversity is any different between individuals with and without ESBL-E carriage.

Noise pollution is one of the major environmental problems of contemporary societies. In urban areas, road transport is the main source impacting the spatio-temporal variation of air quality. This work aims to analyse the spatio-temporal variability of the noise level in the 13th arrondissement during peak hours, focusing on the comparison of noise levels between the COVID-19 lockdown and non-lockdown days. This paper provides data that could be used to evaluate noise mitigation options. Mobile surveys, using EXTECH 4017764 sensors, were used to cover 272 points. In this work, the mobile measurements use the median of instant noise levels measured every 5 s over a 5-min period during the peak period. This study confirms that road traffic appears to be the determining factor in noise pollution. The noise levels calculated in 2020 show a strong spatio-temporal variability explained by the proximity of the emission sources, but also that the noise level decreases by 6-10 dB (A) during the lockdowns. Indeed, near the main roads, 57-63 dB (A) are recorded during the lockdowns, compared to 67-72 dB (A) outside the lockdowns. Mainly the number of vehicles contribute to a large part of the noise level, to which the noise of construction sites can occasionally be added as in the south-eastern part of the study area.

BACKGROUND: Data on the management of patients with cancer presenting with sudden cardiac arrest (SCA) are scarce. We aimed to assess the characteristics and outcomes of SCA according to cancer history. METHODS: Prospective, population-based registry including every out-of-hospital SCA in adults in Paris and its suburbs, between 2011 and 2019, with a specific focus on patients with cancer. RESULTS: Out of 4069 patients who had SCA admitted alive in hospital, 207 (5.1%) had current or past medical history of cancer. Patients with cancer were older (69.2 vs 59.3 years old, p<0.001), more often women (37.2% vs 28.0%, p=0.006) with more frequent underlying cardiovascular disease (41.1% vs 32.5%, p=0.01). SCA happened more often with a non-shockable rhythm (62.6% vs 43.1%, p<0.001) with no significant difference regarding witness presence and cardiopulmonary resuscitation (CPR) performed. Cardiac causes were less frequent among patients with cancer (mostly acute coronary syndromes, 25.5% vs 46.8%, p<0.001) and had more respiratory causes (pulmonary embolism and hypoxaemia in 34.2% vs 10.8%, p<0.001). Still, no difference regarding in-hospital survival was found after SCA in patients with cancer versus other patients (26.2% vs 29.8%, respectively, p=0.27). Public location, CPR by witness and shockable rhythm were independent predictors of in-hospital survival after SCA in the cancer group. CONCLUSIONS: One in 20 SCA occurs in patients with a history of cancer, yet with fewer cardiac causes than in patients who are cancer-free. Still, in-hospital outcomes remain similar even in patients with known cancer. Cancer history should therefore not compromise the initiation of resuscitation in the context of SCA.

BACKGROUND: General practitioners (GPs) were on the front line of the COVID-19 outbreak. Identifying clinical profiles in COVID-19 might improve patient care and enable closer monitoring of at-risk profiles. OBJECTIVES: To identify COVID-19 profiles in a population of adult primary care patients, and to determine whether the profiles were associated with negative outcomes and persistent symptoms. DESIGN, SETTING AND PARTICIPANTS: In a prospective multicentre study, 44 GPs from multiprofessional primary care practices in the Paris area of France recruited 340 consecutive adult patients (median age: 47 years) with a confirmed diagnosis of COVID-19 during the first two waves of the epidemic. METHOD AND OUTCOME: A latent class (LC) analysis with 11 indicators (clinical signs and symptoms) was performed. The resulting profiles were characterised by a 3-month composite outcome (COVID-19-related hospital admission and/or death) and persistent symptoms three and 6 months after inclusion. RESULTS: We identified six profiles: 'paucisymptomatic' (LC1, 9%), 'anosmia and/or ageusia' (LC2, 12.9%), 'influenza-like syndrome with anosmia and ageusia' (LC3, 15.5%), 'influenza-like syndrome without anosmia or ageusia' (LC4, 24.5%), 'influenza-like syndrome with respiratory impairment' (LC5) and a 'complete form' (LC6, 17.7%). At 3 months, 7.4% of the patients were hospitalised (with higher rates in LC5), and 18% had persistent symptoms (with higher rates in LC5 and LC6). At 6 months, 6.4% of the patients had persistent symptoms, with no differences between LCs. CONCLUSION: Our findings might help GPs to identify patients at risk of persistent COVID-19 symptoms and hospital admission and then set up procedures for closer monitoring.
