Abstract
BACKGROUND Human immunodeficiency virus (HIV) infection leads to chronic immune activation/inflammation that can persist in virally suppressed persons on fully active antiretroviral therapy (ART) and increase risk of malignancies. The prognostic role of low CD4:CD8 ratio and elevated CD8 cell counts on the risk of cancer remains unclear. METHODS We investigated the association of CD4:CD8 ratio on the hazard of non-AIDS defining malignancy (NADM), AIDS-defining malignancy (ADM) and most frequent group of cancers in ART-treated people with HIV (PWH) with a CD4 and CD8 cell counts and viral load measurements at baseline. We developed Cox proportional hazard models with adjustment for known confounders of cancer risk and time-dependent cumulative and lagged exposures of CD4:CD8 ratio to account for time-evolving risk factors and avoid reverse causality. RESULTS CD4:CD8 ratios below 0.5, compared to above 1.0, were independently associated with a 12-month time-lagged higher risk of ADM and infection-related malignancies (adjusted hazard ratio 2.61 [95% confidence interval {CI }1.10-6.19] and 2.03 [95% CI 1.24-3.33], respectively). CD4 cell counts below 350 cells/μL were associated with an increased risk of NADMs and ADMs, as did infection, smoking, and body mass index-related malignancies. CONCLUSIONS In ART-treated PWH low CD4:CD8 ratios were associated with ADM and infection-related cancers independently from CD4 and CD8 cell counts and may alert clinicians for cancer screening and prevention of NADM.

Abstract
Effective public health interventions at local level must involve communities and stakeholders beyond the health services spectrum. A dedicated venue for structured discussion will ensure ongoing multi-sectoral collaboration more effectively than convening ad hoc meetings. Such a venue can be created using existing resources, at minimal extra cost. The University Hospital in Nice (France) has established an Open Arena for Public Health which can serve as a model for promoting collaborative partnerships at local level. The Arena has been successful in implementing sustainable interventions thanks to a set of principles, including: non-hierarchical governance and operating, fair representation of stakeholders, consensus as to best available evidence internationally and locally, policy dialogues: open, free-flowing discussions without preconceived solutions, and an experimental approach to interventions.

Abstract
OBJECTIVE Antithrombotic strategies are currently recommended for the treatment of lower extremity artery disease (LEAD) but specific scores to assess the risk of bleeding in these patients are scarce. To fill the gap, the OAC3-PAD bleeding score was recently developed and validated in German cohorts. The aim of this study was to determine whether this score performs appropriately in another real world nationwide cohort. METHODS This 10 year retrospective, multicentre study based on French national electronic health data included patients who underwent revascularisation for LEAD between January 2013 and June 2022. The OAC3-PAD score was calculated and from this, the population was classified into four groups: low, low to moderate, moderate to high and high risk. A binary logistic regression model was applied, with major bleeding occurring at one year (defined using the International Classification of Diseases ICD-10) as the dependent variable. The performance of the OAC3-PAD bleeding score was investigated using a receiver operating characteristic curve. RESULTS Among 161 205 patients hospitalised for LEAD treatment in French institutions, the one year incidence of major bleeding was 13 672 patients (8.5%). The distribution of the population according to the OAC3-PAD bleeding score was: 88 835 patients (55.1%), 34 369 (21.3%), 27 914 (17.3%), and 10 087 (6.3%) in the low, low to moderate, moderate to high, and high risk groups, respectively; with an incidence of one year major bleeding of 5.0%, 9.8%, 13.2%, and 21.3%. The OAC3-PAD model achieved an AUC of 0.650 to predict one year major bleeding following LEAD repair (95% CI 0.645 - 0.655), with a sensitivity of 0.67 and a specificity of 0.57. CONCLUSION This nationwide analysis confirmed the accuracy of the OAC3-PAD model to predict one year major bleeding and served as external validation. Although further studies are required, it adds evidence and perspectives to further generalise its use to guide the management of patients with LEAD.

Abstract
Objectives To refine the clinical spectrum of a very recently identified phenotype associated with LAMB1 end-truncating pathogenic variations. Methods Detailed clinical, neuropsychological, and MRI investigation of 6 patients from 2 unrelated families segregating end-truncating LAMB1 variations. Results All patients harbored a LAMB1 end-truncating pathogenic variation. The specific association of a hippocampal type episodic memory dysfunction and a diffuse leukoencephalopathy was observed in all 4 patients aged older than 50 years, slightly worsening over time in 2 patients with several years of follow-up. Additional unspecific neurologic symptoms are reported, such as episodes of numbness, language troubles, or faintness in these 4 patients and the 2 younger ones. Discussion The association of an extensive leukoencephalopathy with an episodic memory dysfunction of the hippocampal type is strongly suggestive of a LAMB1 end-truncating variation in adults older than 50 years. Early cognitive complaints and imaging abnormalities might exist decades before. Additional transient manifestations can be observed, and this association should lead to LAMB1 screening to avoid unnecessary invasive investigations.

Abstract
Personalized medicine is a challenge for patients with acute myeloid leukemia (AML). The identification of several genetic mutations in several AML trials led to the creation of a personalized prognostic scoring algorithm known as the Knowledge Bank (KB). In this study, we assessed the prognostic value of this algorithm on a cohort of 167 real life AML patients. We compared KB predicted outcomes to real-life outcomes. For patients younger than 60-year-old, OS was similar in favorable and intermediate ELN risk category. However, KB algorithm failed to predict OS for younger patients in the adverse ELN risk category and for patients older than 60 years old in the favorable ELN risk category. These discrepancies may be explained by the emergence of several new therapeutic options as well as the improvement of allogeneic stem cell transplantation (aHSCT) outcomes and supportive cares. Personalized medicine is a major challenge and predictions models are powerful tools to predict patient's outcome. However, the addition of new therapeutic options in the field of AML requires a prospective validation of these scoring systems to include recent therapeutic innovations.

Abstract
Participation in breast cancer screening in urban settings is poor. Identifying factors accounting for participation and non-participation is essential to target priority areas, tackle health inequalities and suggest innovative approaches. We studied organized and individual opportunistic participation in breast cancer screening within the 144 aggregated units for statistical information (Ilôts regroupés pour l'information statistique: IRIS) of the city of Nice from 2019 to 2021. In each IRIS was assessed a local human development index, among potentially active women aged 50 to 59 years and retired women aged 60 to 74 years. Modelling participation and non-participation in screening according to the IRIS units' socio-economical characteristics was performed using the SURE method (Seemingly Unrelated Regression Equations). Over a 2-year period, 24,396 breast screening tests were conducted (11,173 as organised screening, 13,223 as individual opportunistic screening). The local human development index was positively correlated with the two types of screening, respectively. Access to public transport facilitated participation. Managerial status was negatively correlated with organised screening. Single working women had a higher risk of non-participation. With regard to their socio-economic characteristics, screening rates were lower than expected in 16 IRIS units in the city of Nice. Local human development index, access to public transport, family and professional context appear to be associated with breast cancer screening in an urban setting. An innovative approach targeting these factors is called for to reduce health inequalities.

Abstract
BACKGROUND AND AIMS No recommendation regarding antibiotic prophylaxis and preparation modalities are available for patients with esophageal motor disorders who benefit from Per-Oral Endoscopic Myotomy (POEM). The aim of our study was to evaluate their impact on the POEM's safety. PATIENTS AND METHODS This study was a comparative and multicentric retrospective analysis of a database prospectively collected. Patients over 18 years old with esophageal motor disorders confirmed by prior manometry, who underwent POEM were included. The primary endpoint was the occurrence of adverse events, as classified by Cotton, based on whether or not antibiotic prophylaxis was administered. RESULTS A total of 226 patients (median age 52.9 ± 19.12 years [18-105], 116 women [51.3%]) were included. The indication for POEM was mainly type 2 achalasia (n = 135, 60.3%). Antibiotic prophylaxis was administered to 170 patients (75.2%) during 3.93 ± 3.46 days [1-21]. The overall adverse events rate was 9.3% (n = 21). Antibiotic prophylaxis was associated with the occurrence of adverse events (p = .003), but had no impact on their severity (p = .238). Antibiotic prophylaxis didn't influence the effectiveness of POEM (1 [0-4] vs 1 [0-9], p = .231). The use of a liquid diet in the 48 h prior to the procedure was significantly associated with a lower adverse events rate (3.1% vs 6.19%, p = .0002). CONCLUSION The antibiotic prophylaxis during POEM does not prevent adverse events, had no impact on their severity and the efficacy of the procedure. A liquid diet before the procedure should be systematically proposed.

Abstract
Background While air pollution is a major issue due to its harmful effects on human health, few studies focus on its impact on the immune system and vulnerability to viral infections. The lockdown declared following the COVID-19 pandemic represents a unique opportunity to study the large-scale impact of variations in air pollutants in real life. We hypothesized that variations in air pollutants modify Th1 response represented by interferon (IFN) γ production. Methods We conducted a single center paired pilot cohort study of 58 participants, and a confirmation cohort of 320 participants in Nice (France), with for each cohort two samplings at six months intervals. We correlated the variations in the production of IFNγ after non-specific stimulation of participants’ immune cells with variations in key regulated pollutants: NO2, O3, PM2.5, and PM10 and climate variables. Using linear regression, we studied the effects of variations of each pollutant on the immune response. Findings In the pilot cohort, IFNγ production significantly decreased by 25.7% post-lockdown compared to during lockdown, while NO2 increased significantly by 46.0%. After the adjustment for climate variations during the study period (sunshine and temperature), we observed a significant effect of NO2 variation on IFNγ production (P=0.03). In the confirmation cohort IFNγ decreased significantly by 47.8% and after adjustment for environmental factors and intrinsic characteristics we observed a significant effect of environmental factors: NO2, PM10, O3, climatic conditions (sunshine exposure, relative humidity) on variation in IFNγ production (P=0.005, P<0.001, P=0.001, P=0.002 and P<0.001 respectively) but not independently from the BMI at inclusion and the workplace P=0.007 and P<0.001 respectively). Interpretation We show a weakening of the antiviral cellular response in correlation with an increase of pollutants exposition.

Abstract
OBJECTIVE To evaluate the impact of a wearable activity tracker used to encourage physical activity, on disease flares in spondyloarthritis patients. METHODS This randomized controlled trial involved randomizing 108 spondyloarthritis patients into tracker and non-tracker groups. The participants were then subjected to assessments of disease activity, performance (6-Minute Walk Test), and quality of life (Short-Form-36 Health Survey Questionnaire) at the 12th, 24th, and 36th week. The primary outcome of was the change in the frequency of flare episodes (categorized as no flare, flare in <3 days, and flare in >3 days) between baseline and 12 weeks. RESULTS The results of the study showed that at the 12th week, the mean change (Δ) of the number of flares improved in both groups: -0.32 (95% confidence interval (CI) -0.66, 0.02) and -0.38 (95% CI -0.68, 60.09) in the tracker and non-tracker group, respectively. However, the between-group differences were insignificant (p=0.87). Performance scores improved in both groups at the 12th, 24th, and 36th week (p<0.01, p<0.01, and p<0.01). The different dimensions of quality of life also improved at the 12th week (p<0.01). Conversely, moderate flares (p<0.01) and performance (p<0.01) improved over time; however, the influence of a wearable activity tracker was not significant (p=0.29 and p=0.66, respectively). CONCLUSION The use of a wearable activity tracker did not affect the number of flares, performance, and quality of life of spondyloarthritis patients. Nevertheless, this study confirmed the benefits of physical activity on flares, disease activity, quality of life, and physical performance in spondyloarthritis patients.

Abstract
BackgroundOther studies have shown the ability of a wearable activity tracker (TAP) to improve physical activity (PA) in different rheumatic diseases. Given the importance of PA in spondyloarthritis, our hypothesis is that the use of a TAP could improve physical activity and thus disease activity.ObjectivesThe purpose of this study is to evaluate the impact of a TAP used to encourage PA on disease activity in patients with spondyloarthritis.MethodsIn this randomized controlled trial consisting of three 12-week stages (Figure 1). Patients with spondyloarthritis were randomized to a group with TAP (GT), or a group without TAP (GST). For the first stage, both groups received physical activity counseling. In the second 12-week stage, no patients received TAP. In the third 12-week stage, all patients received supervised PA combined with TAP for GT only. Disease activity, performance (assessed by the TM6 6-minute walk test), and quality of life (assessed by the Short Form 36 Health Survey Questionnaire [SF-36]) were assessed at 12, 24, and 36 weeks. The primary endpoint was the progression of relapses between baseline and 12 weeks.Figure 1.ResultsA total of 108 patients were included in the study. At 12 weeks, both groups showed a non-significant improvement in the number of relapses: mean change (Δ), -0.32 [95% CI-0.68;60.09] in GT and Δ, -0.38 [95% CI-0.68;60.09] in GST. But, differences in outcome between groups were not significant (p=0.87). The TM6 was improved in the GT and GST groups at 12, 24, and 36 weeks (p < 0.01, and p < 0.001, respectively). We observed improvement in different dimensions of the SF36, mainly in physical function, emotional role, general health, and physical pain at 12 weeks (p < 0.01).Multivariate analysis showed improvement over time in performance (p < 0.01) and moderate flare-ups (p < 0.01) without the influence of a PAR (p = 0.29, and p = 0.66, respectively).ConclusionTo our knowledge, our study is the first to explore the impact of TAP use on disease activity in spondyloarthritis.We observed an improvement in disease activity, physical performance and quality of life without significant difference between the two groups. The lack of difference could be explained by the encouragement of physical activity to both groups. But also by the fact that our patients presented a significant number of severe relapses. Indeed, authors have shown the limits of the use of TAP in severe diseases, particularly in pulmonary pathologies [1].Our study did not show any effect of the use of a connected object on disease activity. However, this study confirmed the benefits of physical activity on disease activity, quality of life and physical performance in patients with spondyloarthritis.References[1]Bentley CL, Powell L, Potter S, et al.

Abstract
Objectives Initial studies of individuals with coronavirus disease 2019 (COVID-19) revealed that obesity, diabetes and hypertension were associated with severe outcomes. Subsequently, some authors showed that the risk could vary according to age, gender, co-morbidities and medical history. In a nationwide retrospective cohort, we studied the association between these co-morbidities and patients' requirement for invasive mechanical ventilation (IMV) or their death. Methods All French adult inpatients with COVID-19 admitted during the first epidemic wave (February to September 2020) were included. When patients were diagnosed with obesity, diabetes or hypertension for the first time in 2020, these conditions were considered as incident co-morbidities, otherwise they were considered prevalent. We compared outcomes of IMV and in-hospital death according to obesity, diabetes and hypertension, taking age, gender and Charlson's co-morbidity index score (CCIS) into account. Results A total of 134 209 adult inpatients with COVID-19 were included, half of them had hypertension (n = 66 613, 49.6%), one in four were diabetic (n = 32 209, 24.0%), and one in four were obese (n = 32 070, 23.9%). Among this cohort, IMV was required for 13 596 inpatients, and 19 969 patients died. IMV and death were more frequent in male patients (adjusted oods ratio (aOR) 2.0, 95% CI 1.9–2.1 and aOR 1.5, 95% CI 1.4–1.5, respectively), IMV in patients with co-morbidities (aOR 2.1, 95% CI 2.0–2.2 for CCIS = 2 and aOR 3.0, 95% CI 2.8–3.1 for CCIS ≥5), and death in patients aged 80 or above (aOR 17.0, 95% CI 15.5–18.6). Adjusted on age, gender and CCIS, death was more frequent among inpatients with obesity (aOR 1.2, 95% CI 1.1–1.2) and diabetes (aOR 1.2, 95% CI 1.1–1.2). IMV was more frequently necessary for inpatients with obesity (aOR 1.9, 95% CI 1.8–2.0), diabetes (aOR 1.4, 95% CI 1.3–1.4) and hypertension (aOR 1.7, 95% CI 1.6–1.8). Comparatively, IMV was more often required for patients with the following incident co-morbidities: obesity (aOR 3.5, 95% CI 3.3–3.7), diabetes (aOR 2.0, 95% CI 1.8–2.1) and hypertension (aOR 2.5, 95% CI 2.4–2.6). Conclusions Among 134 209 inpatients with COVID-19, mortality was more frequent among patients with obesity and diabetes. IMV was more frequently necessary for inpatients with obesity, diabetes and hypertension. Patients for whom these were incident co-morbidities were particularly at risk. Specific medical monitoring and vaccination should be priorities for patients with these co-morbidities.

Abstract
BACKGROUND Despite significant progress with antiprogrammed cell death protein 1 (PD-1) therapy, a substantial fraction of metastatic melanoma patients show upfront therapy resistance. Biomarkers for outcome are missing and the association of baseline immune function and clinical outcome remains to be determined. We assessed the in vitro nonspecific stimulation of immune response at baseline and during anti-PD-1 therapy for metastatic melanoma. METHODS Previously untreated metastatic melanoma patients received nivolumab and radiotherapy as part of the multicentric phase II trial NIRVANA (NCT02799901). The levels of Th1, Th2 and Th17 cytokines on in vitro non-specific stimulation of innate and adaptive immune cells were measured in patient sera before treatment, and at week 2 and week 6 after the beginning of the treatment, and correlated with tumorous response, progression-free survival (PFS) and occurrence of immune-related adverse events (irAEs). The results in melanoma patients were compared with those of a cohort of 9 sex and age-matched healthy donors. RESULTS Seventeen patients were enrolled in this ancillary study. Median follow-up was 16 months (2.2-28.4). The 12-month PFS rate was 67.7%. The incidence of irAEs of any grade was 58.8%. Without in vitro stimulation no differences in cytokines levels were observed between responders and non-responders. On in vitro stimulation, metastatic patients had lower Th1 cytokine levels than healthy donors at baseline for tumor necrosis factor-α and interferon-γ (IFN-γ) (1136 pg/mL vs 5558 pg/mL, p<0.0001; and 3894 pg/mL vs 17 129 pg/mL, p=0.02, respectively). Responders exhibited increasing cytokine levels from baseline to week 6. Non-responders had lower interleukin 17A (IL-17A) levels at baseline than responders (7 pg/mL vs 32 pg/mL, p=0.03), and lower IFN-γ levels at week 6 (3.3 ng/mL vs 14.5 ng/mL, p=0.03). A lower level of IL-17A at week 2 and a lower level of IFN-γ at week 6 correlated with worse PFS (p=0.04 and p=0.04 respectively). At baseline, patients who developed irAEs had higher IL-6 levels (19.3 ng/mL vs 9.2 ng/mL, p=0.03) and higher IL-17A levels (52.5 pg/mL vs 2.5 pg/mL, p=0.009) than those without irAEs. CONCLUSIONS Our findings indicate that cytokine levels after in vitro non-specific stimulation could be a promising biomarker to predict the outcome of PD-1 inhibition therapy.

Abstract
Importance Although bariatric surgery is effective against morbid obesity, the association of this surgery with the risk of colorectal cancer remains controversial. Objective To assess whether bariatric surgery is associated with altered risk of colorectal cancer among individuals with obesity. Design, Setting, and Participants This retrospective, population-based, multicenter, cohort study based on French electronic health data included 1 045 348 individuals with obesity, aged 50 to 75 years, and free of colorectal cancer at baseline. All inpatients with obesity having data recorded during a hospital stay between 2009 and 2018 by the French national health insurance information system database were followed up for a mean (SD) of 5.3 (2.1) years for those who did not undergo bariatric surgery and 5.7 (2.2) years for those who underwent bariatric surgery. Two groups of patients comparable in terms of age, sex, body mass index, follow-up, comorbidities, and conditions who did or did not undergo surgery were also obtained by propensity score matching. Exposures Bariatric surgery (n = 74 131), including adjustable gastric banding, sleeve gastrectomy, gastric bypass; or no bariatric surgery (n = 971 217). Main Outcomes and Measures Primary outcome was incident colorectal cancer. Standardized incidence ratios were calculated using age-, sex-, and calendar year-matched colorectal cancer incidence among the general French population during the corresponding years. Secondary outcome was incident colorectal benign polyps. Results Among a total of 1 045 348 patients, the mean (SD) age was 57.3 (5.5) years for the 74 131 patients in the surgical cohort vs 63.4 (7.0) years for the 971 217 patients in the nonsurgical cohort. The mean (SD) follow-up was 6.2 (2.1) years for patients who underwent adjustable gastric banding, 5.5 (2.1) years for patients who underwent sleeve gastrectomy, and 5.7 (2.2) years for patients who underwent gastric bypass. In total, 13 052 incident colorectal cancers (1.2%) and 63 649 colorectal benign polyps were diagnosed. The rate of colorectal cancer was 0.6% in the bariatric surgery cohort and 1.3% in the cohort without bariatric surgery. In the latter cohort, 9417 cases were expected vs 12 629 observed, a standardized incidence ratio of 1.34 (95% CI, 1.32-1.36). In the bariatric surgery cohort, 428 cases were expected and 423 observed, a standardized incidence ratio of 1.0 (95% CI, 0.90-1.09). Propensity score-matched hazard ratios in comparable operated vs nonoperated groups were 0.68 (95% CI, 0.60-0.77) for colorectal cancer and 0.56 (95% CI, 0.53-0.59) for colorectal benign polyp. There were fewer new diagnoses of colorectal cancer after gastric bypass (123 of 22 343 [0.5%]) and sleeve gastrectomy (185 of 35 328 [0.5%]) than after adjustable gastric banding (115 of 16 460 [0.7%]), and more colorectal benign polyps after adjustable gastric banding (775 of 15 647 [5.0%]) than after gastric bypass (639 of 20 863 [3.1%]) or sleeve gastrectomy (1005 of 32 680 [3.1%]). Conclusion and Relevance The results of this nationwide cohort study suggested that following bariatric surgery, patients with obesity share the same risk of colorectal cancer as the general population, whereas for patients with obesity who do not undergo bariatric surgery, the risk is 34% above that of the general population.

Abstract
INTRODUCTION Few studies on cancer incidence have been conducted since the adoption of the EU 2000/76/EC waste incineration directive which aimed to limit dioxin emission levels to less than 0.1 ng TEQ/m3 before December 31, 2005. OBJECTIVE To measure cancer incidence among the population exposed to atmospheric emissions from the waste incineration plant near the town of Nice (South-Eastern France), compared to the unexposed population of the Alpes-Maritimes department (A-M). METHODS All primary invasive cancers and haematological malignancies diagnosed among AM residents between 2005 and 2014 were recorded. The exposed surface was modeled on an average dioxin deposition model ≥4.25 ng/m2/year. Each case was geolocated and assigned to one of 36 predefined geographic units of exposed area, or one of 462 units in the unexposed area. The adjusted incidence rate, the standardized incidence ratio and the Comparative Morbidity Figure were calculated for two periods: 2005-2009/2010-2014. RESULTS We recorded 80,865 new cancers in the A-M population. Between 2005 and 2009, we observed a higher incidence among exposed women of acute myeloid leukaemia, myelodysplastic syndromes and myeloma and, among exposed men, of soft tissue sarcomas, myeloma and lung cancer. Between 2010 and 2014, there was no excess incidence among women, while among men incidence of myeloma and lung cancer remained higher. CONCLUSION Only among men, the incidence of myeloma and lung cancer remained higher in the exposed area during the second period. The EU directive resulting in the limitation of atmospheric emissions from incinerators could explain the decrease in incidence of cancers with protracted latency. Consideration of other risk factors and further data collection will be necessary to validate this hypothesis.

Abstract
Introduction
Few studies on cancer incidence have been conducted since the EU 2000/76/EC Waste incineration directive.
Objective
To measure cancer incidence among the population exposed to atmospheric emissions from the Ariane waste incineration plant near Nice, in the Alpes-Maritimes (AM), compared to the unexposed AM population.
Methods
All primary invasive cancers and malignant haematological conditions diagnosed among AM residents from 01/01/2005 to 31/12/2014 recorded by the CRISAPPACA Cancer Observatory, public and private hospitals and the ONCOPACA-Corsica Network were included. The exposed area, based on an average dioxin deposition model, was that with a concentration ≥4.25ng/m2/year. Each case was geolocated and assigned to a predefined geographic unit (IRIS): 36 units in the exposed area, 462 in the unexposed area. The adjusted incidence rate, the standardized incidence ratio (SIR) and the Comparative Morbidity Figure (CMF) were calculated for two periods: 2005-2009/2010-2014.
Results
We recorded 80,865 new cancers in the AM population (1,083,974 residents; 87,462 exposed). For the 2005-2009 period, among exposed women, excess SIR were recorded of acute myeloid leukaemia (SIR = 1.81 [1.03-2.93]), myelodysplastic syndromes (SIR = 2.58 [1.70-3.76]) and myeloma (SIR = 1.64 [1.09-2.37]); in exposed men, of soft tissue sarcomas (SIR = 1.65 [1.05-2, 48]), myeloma (SIR = 2.04 [1.39-2.90]) and lung cancer (SIR = 1.19 [1.03-1.36]). For the 2010-2014 period, there was no excess SIR among women, while among men an excess SIR of myeloma (SIR = 1.76 [1.21-2.47]) and lung cancer (SIR = 1.24 [1.08-1.41]) was observed.
Conclusions
The higher incidence of myeloma and lung cancer in both periods can be explained by their long latency and by other risk factors. The EU Directive appears to have resulted in limiting atmospheric emissions from the incinerator.
Study funded by the Nice Côte d’Azur Metropolis and with the support of the South-PACA Regional Health Agency.

Abstract
BACKGROUND Bariatric surgery (BS) has grown exponentially in France, and long-term anemia due to micronutrient deficiencies has become common. OBJECTIVES The objective of this study was to assess the long-term risk of anemia after BS and to investigate the factors associated with the occurrence of this complication. MATERIALS AND METHODS Data from the French National Health Service database on patients who had undergone gastric bypass (GB), sleeve gastrectomy (SG), or adjustable gastric banding (AGB), between 2008 and 2016 were extracted. Only patients with a primary intervention were considered. RESULTS Data from 306,298 patients (143.733 SG, 79.188 GB, and 36.413 AGB) were analyzed. Overall, 12.930 of them (5.0%) had a diagnosis of anemia due to micronutrient deficiencies as main diagnosis or related diagnosis at time of a hospital stay between 2008 and 2016. In multivariate analysis, GB surgery, female gender, age younger than 52 years, and 25-OH vitamin D deficiency were positively associated with the occurrence of anemia whereas hospital procedural volume was negatively associated. The risk to be diagnosed with anemia after BS was 13.0% after a GB, 5.6% after a SG and 4.0% after an AGB (Log-rank p < 0.0001). The hazard ratio for anemia after GB compared to SG was 2.0 (95% CI 1.9-2.1), adjusted for age and gender. CONCLUSION In France, between 2008 and 2016, 5% of patients had anemia after BS. The risk to develop anemia was 2-fold higher after a GB than after a SG. Young women should be particularly aware of this long-term risk.

Abstract
BACKGROUND Recent evidence has indicated an increased risk of Barrett's esophagus (BE) in the long term after sleeve gastrectomy (SG). AIM The aim of the study is to investigate the spectrum of gastroesophageal reflux disease (GERD) symptoms as well as the prevalence of BE, at minimum 5 years after SG in patients who underwent SG in different bariatric centers of two countries: France and Italy. PATIENTS AND METHODS Five high volume outpatient centers dedicated to bariatric surgery that routinely perform upper GI endoscopy before any bariatric procedures were invited to participate in the study. From January 2017 to June 2018, each center during scheduled postoperative evaluation after surgery asked a minimum 10 consecutive patients, which had performed SG at least 5 years before and with no evidence of BE preoperatively, to undergo another upper GI endoscopy. RESULTS Ninety (66 F) consecutive patients were enrolled. The mean follow-up was 78 ± 15 months, and the mean total body weight loss was 25 ± 12%. The prevalence of BE was 18.8% with no significant difference among centers. Weight loss failure was significantly associated with BE (p < 0.01). The prevalence of GERD symptoms, erosive esophagitis, and the usage of PPIs increased from 22%, 10%, and 22% before the SG to 76%, 41%, and 52% at the time of follow-up, respectively (p < 0.05). CONCLUSIONS This multicenter study show a high rate of BE at least 5 years after SG. Weight loss failure was significantly associated with BE. We suggest to provide systematic endoscopy in these patients to rule out this condition.

Abstract
Background Physical activity programs (PAP) in patients with cardiovascular disease require evidence of cost-utility. To assess improvement in health-related quality of life (QoL) and reduction of health care consumption of patients following PAP, a randomized trial was used. Methods Patients from a health insurance company who had experienced coronary artery disease or moderate heart failure were invited to participate (N = 1891). Positive responders (N = 50) were randomly assigned to a progressively autonomous physical activity (PAPA) program or to a standard supervised physical activity (SPA) program. The SPA group had two supervised sessions per week over 5 months. PAPA group had one session per week and support to aid habit formation (written tips, exercise program, phone call). To measure health-related quality of life EQ-5D utility score were used, before intervention, 6 months (T6) and 1 year later. Health care costs were provided from reimbursement databases. Results Mobility, usual activities and discomfort improved significantly in both group (T6). One year later, EQ-5D utility score was improved in the PAPA group only. Total health care consumption in the intervention group decreased, from a mean of 4097 euros per year before intervention to 2877 euros per year after (p = 0.05), compared to a health care consumption of 4087 euros and 4180 euros per year, in the total population of patients (N = 1891) from the health insurance company. The incremental cost effectiveness ratio was 10,928 euros per QALYs. Conclusion A physical activity program is cost-effective in providing a better quality of life and reducing health care consumption in cardiovascular patients.

Abstract
Background Tremor is an underrecognized feature in certain neuropathy subtypes. Phenomenology shown We show a patient with a disabling neuropathic tremor and mild cerebellar syndrome associated with chronic inflammatory demyelinating polyneuropathy (CIDP) and anti-neurofascin-155 (NF155) antibodies. Educational value Anti-NF155 testing should be considered in patients with CIDP and disabling tremor because of therapeutic implications.

Abstract
BACKGROUND Physical activity can slow the ageing process and preserve autonomy in the elderly. The aim of this study was to assess the combined impact of an organized urban walking circuit and individual coaching on women senior citizens' physical well-being and quality of life. METHODS Insufficiently physically active women >65 years were included in a quasi-experimental trial. Active arm: District with improved urban environment (IUE). Control arm: District without improved urban environment (WIUE). In each district, subjects were randomly allocated to receive coaching (C+ vs. C-). The main outcome measures were endurance, physical activity score, flexibility, quality of life, physical self-esteem, ageing exercise stereotypes, functional health and perceived health at baseline, three (M3) and six (M6) months. RESULTS Fifty-two insufficiently physically active women were included, 23 in IUE and 29 in WIUE. Groups were comparable at baseline. At M3, endurance and physical activity score significantly improved compared with baseline in the IUE group and in the C+ group while no statistically significant change was observed for the WIUE group and the C- group. Moreover, endurance score was higher in the IUE group, whether coupled with coaching or not. After the coaching was removed, the IUE group regresses to baseline overall and the WIUE shows a decrement in endurance. CONCLUSION Our study highlights the positive impact of an improved environment and of individual coaching on the level of physical activity and quality of life of insufficiently physically active elderly women.

Abstract
CONTEXT The objective of this study was to identify collaborative processes involved in a physical activity health promotion project in companies, conducted through a participatory approach in a cross-sectoral partnership, and to estimate the preliminary effects in terms of employee health. METHODS Action research was conducted in an industrial company comprising 240 employees over a 2-year period. This research was based on 4 criteria: description of the actors' network, the opportunities and constraints of the project, the implementation of physical activities, the participation of employees in the various activities, the impacts observed (after 3 months of activities) on physical parameters and quality of life. RESULTS Six work groups selected two activities : muscle-development exercise and Taïchi. We evaluated muscle strengthening activity. The participation rate in the activity was 16%. A higher age, female gender and being a manager or employee rather than a worker were significantly associated with participation. A tendency towards increased physical and mental scores of SF12 was observed. We identified two major barriers: logistic and communicational. CONCLUSION The participatory approach, based on a cross-sectoral partnership, is the determining element of the project's success in a context of local opportunities. Two factors were identified to perpetuate this dynamic and improve the system: rationalization of the structuring of the service and greater resources, particularly financial resources.

Abstract
Background The benefits of supervised physical activity programs in cardiac rehabilitation have been amply demonstrated, but the quantity of physical activity often declines quickly once supervision ends. This trial assesses the effectiveness of an experimental intervention drawing on habit formation theory to maintain physical activity. Methods Cardiovascular patients (N = 47) were randomly assigned to one of two groups. The first group participated in two supervised physical activity (SPA) sessions per week for 20 weeks. The second group was offered a progressively autonomous physical activity (PAPA) program as follows: the same supervised program as the SPA group for 10 weeks and then a further 10 weeks with one supervised session replaced by a strategy to build and sustain the habit of autonomous physical activity. The International Physical Activity Questionnaire (IPAQ; Craig et al. Med Sci Sports Exerc 35(8):1381–1395, 2003) was used to measure the quantity of physical activity, which was the primary outcome. The number of participants was limited, and we thus took multiple IPAQ measurements (at 0, 5, 7, 9 and 12 months after the start of the intervention) and used a mixed model for analysis. Physical condition, automaticity of the physical activity behavior, motivation, and quality of life were examined for changes. Results No significant between-group differences were noted for physical activity behaviors after the program, physical condition, motivation, or behavioral automaticity. The PAPA group nevertheless completed more PA sessions during the intervention, and their quality of life was significantly higher than that of the SPA group at 12 months. Conclusion Although the number of supervised sessions was lower, the progressively autonomous PA program resulted in the same or even higher positive outcomes than the fully supervised PA program.

Abstract
BACKGROUND In this study, we explored in a prospective cohort of morbidly obese women undergoing laparoscopic Roux-en-Y gastric bypass (LRYGP) correlations between baseline anthropometrics, metabolic parameters, resting energy expenditure (REE), body composition, and 1-year % excess body mass index loss (%EBMIL). We also investigated risk factors for insufficient %EBMIL. METHODS One hundred three consecutive women were prospectively evaluated at baseline (age 40.6 ± 11.2, weight 113.9 kg ± 15.3, BMI 43.3 ± 4.9 kg/m2) and 1 year after LRYGP. Weight, excess weight, brachial circumference, waist circumference, fat mass (FM) and fat-free mass (FFM) (measured with bioelectrical impedance analysis), REE, inflammation, insulin resistance, and lipid disturbances were determined before and 1 year after LRYGP. RESULTS At 1 year, mean weight loss was 39.8 kg ± 11.7 and mean EBMIL was 15.2 kg/m2 ± 4.2. Mean %EBMIL was 86% ± 21% (range 30-146%). Baseline brachial circumference, waist circumference and triceps skinfold thickness decreased significantly at 1 year (P < 0.001). Blood glucose and insulin levels, HDL cholesterol, LDL cholesterol, triglycerides, and CRP also decreased significantly (P < 0.001). The mean loss of initial FFM and FM was 9.1 kg ± 8.2 (15%) and 30.7 kg ± 11.8 (53%), respectively. REE on body weight ratio (REE/BW) increased from 15.3 kcal/kg ± 2.8 to 18.4 kcal/kg ± 2.5 (p < 0.0001) and REE on FFM ratio decreased from 31.2 to 28.7 kcal/day/kg (p < 0.001). Preoperative waist circumference (r = -0.3; P < 0.001), blood glucose level (r = -0.37; P < 0.001), and CRP (r = -0.28; P = 0.004) were negatively correlated with EBMIL% 1 year after surgery. Among baseline body composition parameters, only preoperative FM was negatively correlated with %EBMIL (r = -0.23; p = 0.02). One year after surgery FM change was negatively correlated with EBMIL% (r = -0.49; P < 0.001) while FFM/BW ratio was positively correlated with %EBMIL (r = 0.71; P < 0.001). Increase in REE/BW at 1 year was positively correlated with %EBMIL (r = 0.47; p < 0.001). On multivariate analysis, baseline blood glucose level (OR = 1.77; CI 95%: [1.3-2.4]) was the only predictive factor of EBMIL <60% at 1 year. CONCLUSION LRYGB has beneficial effects on clinical, biological parameters, and body composition. Increasing the proportion of FFM on total BW and REE/BW is associated with better results in terms of weight loss. Baseline glucose level may be helpful in identifying poor responders to LRYGBP.

Abstract
BACKGROUND The Chernobyl nuclear power plant accident occurred in Ukraine on April 26th 1986. In France, the radioactive fallout and thyroid radiation doses were much lower than in highly contaminated areas. However, a number of risk projections have suggested that a small excess in differentiated thyroid cancer (DTC) might occur in eastern France due to this low-level fallout. In order to investigate this potential impact, a case-control study on DTC risk factors was started in 2005, focusing on cases who were less than 15 years old at the time of the Chernobyl accident. Here, we aim to evaluate the relationship between some specific reports of potentially contaminated food between April and June 1986 - in particular fresh dairy products and leafy vegetables - and DTC risk. METHODS After excluding subjects who were not born before the Chernobyl accident, the study included 747 cases of DTC matched with 815 controls. Odds ratios were calculated using conditional logistic regression models and were reported for all participants, for women only, for papillary cancer only, and excluding microcarcinomas. RESULTS The DTC risk was slightly higher for participants who had consumed locally produced leafy vegetables. However, this association was not stronger in the more contaminated areas than in the others. Conversely, the reported consumption of fresh dairy products was not statistically associated with DTC risk. CONCLUSION Because the increase in DTC risk associated with a higher consumption of locally produced vegetables was not more important in the most contaminated areas, our study lacked power to provide evidence for a strong association between consumption of potentially contaminated food and DTC risk.

Abstract
BACKGROUND In retrospective case-control studies performed following nuclear tests or nuclear accidents, individual thyroid radiation dose reconstructions are based on fallout and meteorological data from the residential area, demographic characteristics, and lifestyle as well as dietary information. Collecting the latter is a controversial step, as dietary declarations may be affected by the subjects' beliefs about their risk behavior. This report analyses the potential for such bias in a case-control study performed in eastern France. METHODS The study included 765 cases of differentiated thyroid carcinoma matched with 831 controls. Risk perceptions and beliefs of cases and controls were compared using Chi2 tests and differences in dietary reports were analyzed using a two-way ANOVA. RESULTS In general, atmospheric pollution and living near a nuclear power plant were the two major risks that may influence thyroid cancer occurrence cited by cases and controls. When focusing in particular on the consequences of the Chernobyl accident, cases were more likely to think that the consequences were responsible for thyroid cancer occurrence than controls. Vegetable consumption during the two months after the Chernobyl accident was correlated with the status of subjects, but not to their beliefs. Conversely, consumption of fresh dairy products was not correlated with the status or beliefs of subjects. CONCLUSION We found no evidence of systematic bias in dietary reports according to the status or beliefs held by subjects about the link between thyroid cancer occurrence and Chernobyl fallout. As such, these dietary reports may be used in further studies involving individual dosimetric reconstructions.

Abstract
PURPOSE Physical activity has been hypothesized to influence cancer occurrence through several mechanisms. To date, its relation with thyroid cancer risk has been examined in relatively few studies. We pooled 2 case-control studies conducted in Cuba and Eastern France to assess the relationship between self-reported practice of recreational physical activity since childhood and thyroid cancer risk. METHODS This pooled study included 1,008 cases of differentiated thyroid cancer (DTC) matched with 1,088 controls (age range 9-35 and 17-60 years in the French and Cuban studies, respectively). Risk factors associated with the practice of recreational physical activity were estimated using OR and 95% CI. Logistic regressions were stratified by age class, country, and gender and were adjusted for ethnic group, level of education, number of pregnancies for women, height, BMI, and smoking status. RESULTS Overall, the risk of thyroid cancer was slightly reduced among subjects who reported recreational physical activity (OR = 0.8; 95% CI 0.5-1.0). The weekly frequency (i.e. h/week) seems to be more relevant than the duration (years). CONCLUSION Long-term recreational physical activity, practiced since childhood, may reduce the DTC risk. However, the mechanisms whereby the DTC risk decreases are not yet entirely clear.

Abstract
The incidence of thyroid cancer has risen over the past decade, along with a rise in obesity. We studied the role of anthropometric risk factors for differentiated thyroid cancer at the time of diagnosis and at age 20 years in a case-control study conducted in eastern France between 2005 and 2010. The study included 761 adults diagnosed with differentiated thyroid cancer before 35 years of age between 2002 and 2006. They were matched with 825 controls from the general population. Odds ratios were calculated using conditional logistic regression models and were reported for all participants, those with papillary cancer only, and women only. The risk of thyroid cancer was higher for participants with a high body surface area (BSA), great height, or excess weight and for women with a high body fat percentage. Conversely, no significant association was found between body mass index and the risk of thyroid cancer. In the present study, we provide further evidence of the role of BSA and excess weight in the risk of thyroid cancer. These epidemiologic observations should be confirmed by further exploration of the biological mechanisms responsible for the associations of obesity and BSA with thyroid cancer.

Abstract
BACKGROUND Cancer incidence and prevalence estimates are necessary to inform health policy, to predict public health impact and to identify etiological factors. Registers have been used to estimate the number of cancer cases. To be reliable and useful, cancer registry data should be complete. Capture-recapture is a method for estimating the number of cases missed, originally developed in ecology to estimate the size of animal populations. Capture recapture methods in cancer epidemiology involve modelling the overlap between lists of individuals using log-linear models. These models rely on assumption of independence of sources and equal catchability between individuals, unlikely to be satisfied in cancer population as severe cases are more likely to be captured than simple cases. METHODS To estimate cancer population and completeness of cancer registry, we applied M(th) models that rely on parameters that influence capture as time of capture (t) and individual heterogeneity (h) and compared results to the ones obtained with classical log-linear models and sample coverage approach. For three sources collecting breast and colorectal cancer cases (Histopathological cancer registry, hospital Multidisciplinary Team Meetings, and cancer screening programmes), individual heterogeneity is suspected in cancer population due to age, gender, screening history or presence of metastases. Individual heterogeneity is hardly analysed as classical log-linear models usually pool it with between-"list" dependence. We applied Bayesian Model Averaging which can be applied with small sample without asymptotic assumption, contrary to the maximum likelihood estimate procedure. RESULTS Cancer population estimates were based on the results of the M(h) model, with an averaged estimate of 803 cases of breast cancer and 521 cases of colorectal cancer. In the log-linear model, estimates were of 791 cases of breast cancer and 527 cases of colorectal cancer according to the retained models (729 and 481 histological cases, respectively). CONCLUSIONS We applied M(th) models and Bayesian population estimation to small sample of a cancer population. Advantage of M(th) models applied to cancer datasets, is the ability to explore individual factors associated with capture heterogeneity, as equal capture probability assumption is unlikely. M(th) models and Bayesian population estimation are well-suited for capture-recapture in a heterogeneous cancer population.

Abstract
Objective.To evaluate the knowledge of healthcare students after four curricula on infection control and to identify sources of information.Design.Cross-sectional study.Setting.Four healthcare schools at Rouen University (Rouen, France).Participants.Medical students, nursing students, assistant radiologist students, and physiotherapist students taking public health courses.Methods.To measure students' knowledge of infection control and their sources of information, 6 multiple-choice questions were asked about 3 specific areas: standard precautions, hand hygiene, and nosocomial infection. Each questionnaire section had 10 possible points, for an overall perfect score of 30. The sources of information for these 3 areas were also recorded: self-learning, practice training in wards, formal training in wards, and teaching during the curriculum. A logistic regression analysis was performed to identify factors associated with acceptable level of knowledge.Results.Three hundred fifty students (107 medical students, 78 nursing students, 71 physiotherapist students, and 94 assistant radiologist students) were included in the study. The mean overall score (±SD) was 21.5 ± 2.84. Nursing students had a better mean overall score (23.2 ± 2.35) than did physiotherapist students (21.9 ± 2.36), medical students (21.1 ± 2.35), and assistant radiologist students (20.5 ± 3.04; P < .001). The mean scores (±SD) for the component sections of the questionnaire were 8.5 ±1.4 for standard precautions, 7.4 ± 1.26 for hand hygiene, and 5.7 ± 1.55 for nosocomial infections (P < .001). The main source of information was material taught during the curriculum. Results of multivariate analysis indicate that the probability of attaining acceptable knowledge in each area was smaller for medical students and assistant radiologist students than for nursing students.Conclusion.The overall score for infection control indicated that instruction was effective; however, knowledge levels were different by area (the best scores were results of tests of standard precautions) and curriculum (nursing students achieved the best overall score). Ward training for daily infection control practice (ie, bedside instructions training and course work) could be improved for healthcare students.

Abstract
The incidence of thyroid cancer has increased in eastern Europe since the Chernobyl nuclear power plant accident. Although the radioactive fallout was much less severe and the thyroid radiation dose was much lower in France, a case-control study was initiated in eastern France. The present study included 633 young women who were diagnosed with differentiated thyroid cancer before 35 years of age between 2002 and 2006 and matched with 677 controls. Face-to-face interviews were conducted from 2005 to 2010. Odds ratios were calculated using conditional logistic regressions and were reported in the total group and by histopathological type of cancer ("only papillary" and "excluding microcarcinomas"). The risk of thyroid cancer was higher in women who had a higher number of pregnancies, used a lactation suppressant, or had early menarche. Conversely, breastfeeding, oral contraceptive use, and late age at first pregnancy were associated with a lower risk of thyroid cancer. No association was observed between thyroid cancer and having irregular menstrual cycle, undergoing treatment for menstrual cycle regularity shortly after menarche, having a cessation of menstruation, use of another contraceptive, history of miscarriage or abortion for the first pregnancy, or having had gestational diabetes. This study confirms the role of hormonal and reproductive factors in thyroid cancer, and our results support the fact that exposure to estrogens increases thyroid cancer risk.

Abstract
BACKGROUND Measuring adenoma detection is a priority in the quality improvement process for colonoscopy. Our aim was (1) to determine the most appropriate quality indicators to assess the neoplasia yield of colonoscopy and (2) to establish benchmark rates for the French colorectal cancer screening programme. METHODS Retrospective study of all colonoscopies performed in average-risk asymptomatic people aged 50-74 years after a positive guaiac faecal occult blood test in eight administrative areas of the French population-based programme. RESULTS We analysed 42,817 colonoscopies performed by 316 gastroenterologists. Endoscopists who had an adenoma detection rate around the benchmark of 35% had a mean number of adenomas per colonoscopy varying between 0.36 and 0.98. 13.9% of endoscopists had a mean number of adenomas above the benchmark of 0.6 and an adenoma detection rate below the benchmark of 35%, or inversely. Correlation was excellent between mean numbers of adenomas and polyps per colonoscopy (Pearson coefficient r=0.90, p<0.0001), better than correlation between mean number of adenomas and adenoma detection rate (r=0.84, p=0.01). CONCLUSION The mean number of adenomas per procedure should become the gold standard to measure the neoplasia yield of colonoscopy. Benchmark could be established at 0.6 in the French programme.

Abstract
Magstream and OC Sensor quantitative immunochemical faecal occult blood tests (IFOBT) have shown better performances than guaiac (G) tests in colorectal cancer screening, however Magstream and OC Sensor have never been compared. We hypothesized that similar performances could be observed with Magstream and OC Sensors, provided a similar cut-off (expressed in concentration of haemoglobin in the stools) is used. We performed a literature-based indirect comparison between these tests, taking into account the cut-off, the number of samples, and the way they were combined (I2+: at least one positive sample of 2; I2++: both positive samples; I1: only one sample). Six studies conducted in general average-risk populations were included in this review. For each [test]*[cut-off], positivity rate (PR) decreased and predictive positive value (PPV) increased from I2+ to I1 and I2++. For similar PR, PPV with OC Sensor was greater than with Magstream. This could be due to factors other than the test, because PPVs associated with GFOBT in studies evaluating OC Sensor were greater than PPVs associated with GFOBT in the study evaluating Magstream. Direct comparison between Magstream and OC Sensor is needed to confirm the suspected superiority of OC Sensor.

Abstract
INTRODUCTION Cancer population studies require reliable and complete baseline data, which should theoretically be available by collecting histopathology records. The completeness of such a collection was evaluated using capture-recapture analysis based on three data sources concerning breast and colorectal cancers over an identical period and within the same geographical area. METHOD The total number of breast and colon cancer cases was estimated using capture-recapture analysis based on the number of cases which were common or not between sources recording screened, diagnosed and treated cancers in the French Alpes Maritimes district. RESULT The estimated total number of new cases of breast cancer diagnosed among Alpes Maritimes residents women aged 50-75 was 791 (95% CI: 784-797) in 2008. Of these 791 cases, 729 were identified through histopathology records, thus amounting to 92.2% completeness (95% CI: 91.5-93.0%). The total estimated number of new cases of colorectal cancer diagnosed among Alpes Maritimes residents aged 50-75 was 527 (95% CI: 517-536). Of these 527 cases, 481 were identified through histopathology records, thus amounting to 91.3% completeness (95% CI: 89.7-93.0%). CONCLUSION The estimated completeness of cancer records collected from histopathology laboratories was higher than 90% for new cases of breast and colorectal cancer within the age range concerned by the screening programme. A verified and validated histopathology data collection may be useful for cancer population studies.
